Full Text Available BACKGROUND: Scabies is recognised as a major public health problem in many countries, and is responsible for significant morbidity due to secondary bacterial infection of the skin causing impetigo, abscesses and cellulitis, that can in turn lead to serious systemic complications such as septicaemia, kidney disease and, potentially, rheumatic heart disease. Despite the apparent burden of disease in many countries, there have been few large-scale surveys of scabies prevalence or risk factors. We undertook a population-based survey in Fiji of scabies and impetigo to evaluate the magnitude of the problem and inform public health strategies. METHODOLOGY/PRINCIPAL FINDINGS: A total of 75 communities, including villages and settlements in both urban and rural areas, were randomly selected from 305 communities across the four administrative divisions, and all residents in each location were invited to participate in skin examination by trained personnel. The study enrolled 10,887 participants. The prevalence of scabies was 23.6%, and when adjusted for age structure and geographic location based on census data, the estimated national prevalence was 18.5%. The prevalence was highest in children aged five to nine years (43.7%, followed by children aged less than five (36.5%, and there was also an indication of prevalence increasing again in older age. The prevalence of scabies was twice as high in iTaukei (indigenous Fijians compared to Indo-Fijians. The prevalence of impetigo was 19.6%, with a peak in children aged five to nine years (34.2%. Scabies was very strongly associated with impetigo, with an estimated 93% population attributable risk. CONCLUSIONS: As far as we are aware, this is the first national survey of scabies and impetigo ever conducted. We found that scabies occurs at high levels across all age groups, ethnicities, and geographical locations. Improved strategies are urgently needed to achieve control of scabies and its complications in

Ciguatera is a widespread ichthyosarcotoxism which causes gastrointestinal, neurological and cardiovascular disturbances. Investigations conducted by ORSTOM in 1992 highlighted a prevalence of 25% in the adult population of Noumea, New Caledonia. The main objective of our study was to estimate the prevalence of ciguatera and the persistence of symptoms by sex and by ethnicity among adult patients of a nurse clinic in Noumea in 2005. Investigations were conducted from 1st January to 15th June 2005. During this period, 559 patients were included: 165 males and 394 females. Among them, 37.8% were poisoned at least once in their life. This rate was independent of gender and ethnicity, but was significantly higher in age groups above 40 years. Neurological signs were more frequent (>80%) than gastrointestinal (ciguatera prevalence, and its chronicity for 1/5 of European cases. Copyright 2009 Elsevier Ltd. All rights reserved.

Full Text Available Abstract Background The global rise and spread of antibiotic resistance is limiting the usefulness of antibiotics in the prevention and treatment of infectious diseases. The use of antibiotic stewardship programs guided by local data on prescribing practices is a useful strategy to control and reduce antibiotic resistance. Our objective in this study was to determine the prevalence and indications for use of antibiotics at the Korle-Bu Teaching Hospital Accra, Ghana. Methods An antibiotic point prevalence survey was conducted among inpatients of the Korle-Bu Teaching Hospital between February and March 2016. Folders and treatment charts of patients on admission at participating departments were reviewed for antibiotics administered or scheduled to be administered on the day of the survey. Data on indication for use were also collected. Prevalence of antibiotic use was determined by dividing the number of inpatients on antibiotics at the time of survey by the total number of patients on admission. Results Of the 677 inpatients surveyed, 348 (51.4%, 95% CI, 47.6–55.2 were on treatment with antibiotics. Prevalence was highest among Paediatric surgery where 20/22 patients (90.9%, 95% CI, 70.8–98.9 were administered antibiotics and lowest among Obstetrics patients with 77/214 (36%, 95% CI, 29.5–42.8. The indications for antibiotic use were 245/611 (40.1% for community-acquired infections, 205/611 (33.6% for surgical prophylaxis, 129/611 (21.1% for healthcare associated infections and 33/611 (5.4% for medical prophylaxis. The top five antibiotics prescribed in the hospital were metronidazole 107 (17.5%, amoxicillin-clavulinic acid 82 (13.4%, ceftriaxone 17(12.1%, cefuroxime 61 (10.0%, and cloxacillin 52 (8.5% respectively. Prevalence of meropenem and vancomycin use was 12(2% and 1 (.2% respectively. The majority of patients 181 (52% were being treated with two antibiotics. Conclusion This study indicated a high prevalence of antibiotic use among

In China, several measures have been adopted to decrease unnecessary antimicrobial overuse since 2010. This study aimed to identify characteristics of antimicrobial use in Chinese hospitals after implementing these measures and to explore additional targets for future antimicrobial stewardship. In 2012, point prevalence surveys conducted in Chinese hospitals included inpatients who were admitted for at least 24 hours. Details regarding infection, antimicrobial use, and bacterial cultures were recorded. A survey of 786,028 inpatients in 1,313 hospitals included prevalence of health care-associated (3.22%) and community-acquired infections (22.52%); antimicrobial use prevalence (AUP, 38.39%); bacterial culture rate (BCR, 40.16%); and proportions of administration of a single antimicrobial (75.33%), therapeutic (23.16%), prophylactic (11.99%), and therapeutic plus prophylactic (3.24%) AUP rates. Prophylactic AUP rates of hospitals with AUP rates for surgical patients with classes I, II, and III wounds were 45.19%, 68.18%, and 68.47%, respectively. Prophylactic AUP rates for surgical patients decreased with increasing hospital bed numbers. These indices varied among different hospital departments. More efforts are needed toward small hospitals, prophylactic antimicrobial use for surgical patients, and departments with low BCRs to optimize the clinical antimicrobial use.

There are not enough data on the epidemiology of asthma in the Kingdom of Saudi Arabia (KSA). We analyzed data from a national household survey conducted in KSA in 2013 to estimate prevalence, associated risk factors and control measurements of asthma. The Saudi Health Interview Survey was a cross-sectional national multistage survey of 10,735 individuals aged 15 years or older. The survey included a detailed household questionnaire and a physical exam. We used self-reported clinical diagnosis of asthma to assess prevalence of asthma. The prevalence of asthma in KSA was 4.05 % (95 % confidence interval [CI]: 3.54-4.62 %). Asthma was less frequent in individuals with higher education but higher in former smokers and obese individuals. Around 76.7 % of asthma patients (95 % CI: 70.6-82.0 %) experienced an asthmatic attack, and 61.6 % (95 % CI: 54.4-68.4 %) visited a hospital/emergency room because of asthma during the past year. Asthma attack was less frequent in older patients (odds ratio [OR] = 0.78, 95 %CI: 0.59-0.96 for each decade of life). Current use of medication for asthma was highly associated with asthma attacks (OR = 9.14, 95 % CI: 3.29-25.38). Asthma attack was also more frequent in individuals who were exposed to secondhand smoking (OR = 2.17, 95 %CI: 1.05-4.45) and those who were obese (OR = 3.01, 95 %CI: 1.34-6.78). Saudi Arabia has a relatively low prevalence of diagnosed asthma; however, many of the patients with known asthma do not have it under good control. Our study calls for programs to inform patients about the importance and proper means of controlling their condition. Implementing and monitoring of clinical guidelines can also help to improve asthma control among patients as well as identify undiagnosed cases.

Very little is known regarding the global variations in the prevalence of food allergies. The EuroPrevall-INCO project has been developed to evaluate the prevalence of food allergies in China, India and Russia using the standardized methodology of the EuroPrevall protocol used for studies in the European Union. The epidemiological surveys of the project were designed to estimate variations in the prevalence of food allergy and exposure to known or suspected risk factors for food allergy and to compare the data with different European countries. Random samples of primary schoolchildren were recruited from urban and rural regions of China, Russia and India for screening to ascertain possible adverse reactions to foods. Cases and controls were then selected to answer a detailed questionnaire designed to evaluate the possible risk factors of food allergies. Objective evidence of sensitisation including skin-prick test and serum specific IgE measurement was also collected. More than 37 000 children from the three participating countries have been screened. The response rates for the screening phase ranged from 83% to 95%. More than 3000 cases and controls were studied in the second phase of the study. Further confirmation of food allergies by double blind food challenge was conducted. This will be the first comparative study of the epidemiology of food allergies in China, India, and Russia using the same standardized methodology. The findings of these surveys will complement the data obtained from Europe and provide insights into the development of food allergy.

Trachoma, caused by ocular infection with Chlamydia trachomatis, is the leading infectious cause of blindness worldwide. We conducted the first population-based trachoma prevalence survey in the Casamance region of Senegal to enable the Senegalese National Eye Care Programme (NECP) to plan its trachoma control activities. The World Health Organization (WHO) guidelines state that any individual with trachomatous trichiasis (TT) should be offered surgery, but that surgery should be prioritised where the prevalence is >0.1%, and that districts and communities with a trachomatous inflammation, follicular (TF) prevalence of ≥10% in 1-9 year-olds should receive mass antibiotic treatment annually for a minimum of three years, along with hygiene promotion and environmental improvement, before re-assessing the prevalence to determine whether treatment can be discontinued (when TF prevalence in 1-9 year-olds falls 1% in all districts. With a prevalence <5%, TF does not appear to be a significant public health problem in this region. However, TF monitoring and surveillance at sub-district level will be required to ensure that elimination targets are sustained and that TF does not re-emerge as a public health problem. TT surgery remains the priority for trachoma elimination efforts in the region, with an estimated 1819 TT surgeries to conduct.

Several epidemiological studies have been done on conduct disorder in the Middle East, but no systematic review has been conducted on this topic. Thus, we aimed at investigating the prevalence of conduct disorder in the Middle East in this systematic review of the literature. We searched all the cross-sectional studies in the scientific databases of PubMed, Scopus, Google Scholar, Index Medicus for the Eastern Mediterranean Region, Islamic World Science Citation Center, and Grey Literature including conference proceedings, and hand searching of key journals from 1995 to the end of 2014. Included studies described the prevalence of conduct disorder prior to age of 18, with any type of random or non-random sampling for at least one gender in the general or school-based populations who resided in Middle Eastern countries. Two reviewers assessed the quality of the included studies independently and extracted the relevant data. Twenty-four studies were included in this review. Sample sizes varied from 136 to 9636 with the age range of 6-18 years. These studies were conducted in Iran, Turkey, Israel, Cyprus, Egypt, United Arab Emirates, Iraq, Afghanistan, Yemen, and Palestine. Strengths and Difficulties Questionnaire (SDQ) was used in most of the included studies. The prevalence of conduct disorder was reported from 2.4% by diagnostic criteria taken from DSM-IV-TR in Iraq to 32.9% by SDQ in Iran; the prevalence rates ranged from 1 to 29.9% for females and from 3.3 to 34.6% for males. However, the prevalence of conduct disorder was reported 0.34% by the diagnostic instrument of Kiddie Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime in Iranian children and adolescents. The prevalence of conduct disorder in this study was higher than the worldwide prevalence, thus, it seems essential to design preventive and treatment programs for children and adolescents with conduct disorder.

In 2006, the Hospital Infection Society was funded by the respective health services in England, Wales, Northern Ireland and the Republic of Ireland to conduct a prevalence survey of healthcare-associated infection (HCAI). Here, we report the prevalence of pneumonia and lower respiratory tract infection other than pneumonia (LRTIOP) in these four countries. The prevalence of all HCAIs was 7.59% (5743 out of 75 694). Nine hundred (15.7%) of these infections were pneumonia, and 402 (7.0%) were LRTIOP. The prevalence of both infections was higher for males than for females, and increased threefold from those aged <35 to those aged >85 years (P<0.001). At the time of the survey or in the preceding seven days, 23.7% and 18.2% of patients with pneumonia and LRTIOP, respectively, were mechanically ventilated compared to 5.2% of patients in the whole study population. Meticillin-resistant Staphylococcus aureus (MRSA) was the cause of pneumonia and LRTIOP in 7.6% and 18.1% of patients, respectively (P<0.001). More patients with LRTIOP (4.2%) had concurrent diarrhoea due to Clostridium difficile compared to patients with pneumonia (2.4%), but this did not reach statistical significance. Other HCAIs were present in 137 (15.2%) of patients with pneumonia and 66 (16.4%) of those with LRTIOP. The results suggest that reducing instrumentation, such as mechanical ventilation where possible, should help reduce infection. The higher prevalence of MRSA as a cause of LRTIOP suggests a lack of specificity in identifying the microbial cause and the association with C. difficile emphasises the need for better use of antibiotics.

Full Text Available Although the largest buffalo herd in the occident is in the north region of Brazil, few studies have been conducted to assess the prevalence of selected parasitic diseases in buffalo herd. The present study was therefore conducted to investigate the epidemiological of Toxoplasma gondii, Neospora caninum, Anaplasma marginale, Babesia bigemina, and Babesia bovis in water buffaloes in the north region of Brazil. A total of 4796 buffalo blood samples were randomly collected from five provinces and simultaneously analyzed by the IFAT and ELISA. The serological prevalence of T. gondii and N. caninum was 41.3% and 55.5% in ELISA and 35.7% and 48.8% in IFAT, respectively. The overall prevalence of A. marginale, B. bovis, and B. bigemina was 63%, 25%, and 21% by ELISA and 50.0%, 22.5%, and 18.8% by IFAT, respectively. This study shows valuable information regarding the serological survey of selected bovine pathogens in water buffaloes in the north region of Brazil which will likely be very beneficial for the management and control programs of this disease.

Estimating micro area behavioural risk factor prevalence from large population-based surveys: a full Bayesian approach

Directory of Open Access Journals (Sweden)

L. Seliske

2016-06-01

Full Text Available Abstract Background An important public health goal is to decrease the prevalence of key behavioural risk factors, such as tobacco use and obesity. Survey information is often available at the regional level, but heterogeneity within large geographic regions cannot be assessed. Advanced spatial analysis techniques are demonstrated to produce sensible micro area estimates of behavioural risk factors that enable identification of areas with high prevalence. Methods A spatial Bayesian hierarchical model was used to estimate the micro area prevalence of current smoking and excess bodyweight for the Erie-St. Clair region in southwestern Ontario. Estimates were mapped for male and female respondents of five cycles of the Canadian Community Health Survey (CCHS. The micro areas were 2006 Census Dissemination Areas, with an average population of 400–700 people. Two individual-level models were specified: one controlled for survey cycle and age group (model 1, and one controlled for survey cycle, age group and micro area median household income (model 2. Post-stratification was used to derive micro area behavioural risk factor estimates weighted to the population structure. SaTScan analyses were conducted on the granular, postal-code level CCHS data to corroborate findings of elevated prevalence. Results Current smoking was elevated in two urban areas for both sexes (Sarnia and Windsor, and an additional small community (Chatham for males only. Areas of excess bodyweight were prevalent in an urban core (Windsor among males, but not females. Precision of the posterior post-stratified current smoking estimates was improved in model 2, as indicated by narrower credible intervals and a lower coefficient of variation. For excess bodyweight, both models had similar precision. Aggregation of the micro area estimates to CCHS design-based estimates validated the findings. Conclusions This is among the first studies to apply a full Bayesian model to complex

To analyse trends in diarrhoea prevalence by maternal education, access to clean water and improved sanitation, household wealth index; to identify the sources of variation and assess contribution of changes in socioeconomic characteristics in the Democratic Republic of Congo (DRC). Consecutive cross-sectional surveys. DRC. The databases contain information on 9748 children from the 2001 Multiple Indicators Cluster Survey and 7987 children from the 2007 Demographic and Health Survey. N/A. Whether the child had diarrhoea 14 days preceding the survey. The overall prevalence of diarrhoea decreased by 26 percent (from 22.1% in 2001 to 16.4% in 2007). Findings from the three complementary statistical methods are consistent and confirm a significant decrease in diarrhoea regardless of socioeconomic characteristics. Changes in behaviour and/or in public health policy seem to be the likely main source of the change. There were no significant changes in diarrhoea prevalence associated with variation of the population structure. It is worth mentioning that the decrease in diarrhoea prevalence is in contrast to the generalised poor living conditions of the population. Therefore, it is difficult to ascertain whether the decline in diarrhoea prevalence was due to real improvement in public-health policy or to data quality issues. The decline of diarrhoea prevalence in our study need to be further investigated by conducting district-based or provincial-based studies to validate findings from household surveys such as Demographic and Health Surveys and Multiple Indicators Cluster Survey taking into account the current context of the country: ongoing conflict, poor socioeconomic and poor health infrastructure. However, improvement in living conditions such as access to clean water and improved sanitation will contribute to accelerate the reduction of diarrhoea prevalence as well as reduction of child mortality.

Obesity is recognised as a serious public health issue, due to its associated morbidity and mortality. This study aimed at estimating the prevalence of overweight and obesity in the Portuguese population through direct measurements obtained by the 1st National Health Examination Survey (INSEF 2015) and to identify its associated sociodemographic factors. INSEF was a nationally representative cross-sectional prevalence study conducted on 4911 Portuguese adults aged 25-74 years, in 2015. Height and weight were measured according to the European Health Examination Survey procedures. Poisson regression was used to estimate the adjusted prevalence ratios of overweight and obesity according to age, marital status, occupational activity, education, urbanization of living area and smoking status. Overall prevalences of overweight and obesity were 39.1% and 28.6%, respectively. The prevalence of overweight was higher among men (45.5% vs 33.2%) while the prevalence of obesity was higher among women (32% vs 25%). The sociodemographic factors associated with overweight and obesity were age, marital status and education. Smoking status was associated with overweight and obesity but only in women. INSEF suggests that a high prevalences of overweight and obesity are found in older individuals, married, with lower education levels and non-smoking women. Public health interventions are urgently required for obesity prevention, namely throughout health literacy strategies. Copyright © 2017 Asia Oceania Association for the Study of Obesity.

A prevalence survey is a time-saving and useful tool for obtaining an overview of healthcare-associated infection (HCAI) either in a single hospital or nationally. Direct comparison of prevalence rates is difficult. We evaluated the impact of case-mix adjustment on hospital-specific prevalences. All five tertiary care, all 15 secondary care and 10 (25% of 40) other acute care hospitals took part in the first national prevalence survey in Finland in 2005. US Centers for Disease Control and Prevention criteria served to define HCAI. The information collected included demographic characteristics, severity of the underlying disease, use of catheters and a respirator, and previous surgery. Patients with HCAI related to another hospital were excluded. Case-mix-adjusted HCAI prevalences were calculated by using a multivariate logistic regression model for HCAI risk and an indirect standardisation method. Altogether, 587 (7.2%) of 8118 adult patients had at least one infection; hospital-specific prevalences ranged between 1.9% and 12.6%. Risk factors for HCAI that were previously known or identified by univariate analysis (age, male gender, intensive care, high Charlson comorbidity and McCabe indices, respirator, central venous or urinary catheters, and surgery during stay) were included in the multivariate analysis for standardisation. Case-mix-adjusted prevalences varied between 2.6% and 17.0%, and ranked the hospitals differently from the observed rates. In 11 (38%) hospitals, the observed prevalence rank was lower than predicted by the case-mix-adjusted figure. Case-mix should be taken into consideration in the interhospital comparison of prevalence rates. Copyright 2010 The Hospital Infection Society. Published by Elsevier Ltd. All rights reserved.

The use of 'poppers' (volatile alkyl nitrites) has been associated with the development of visual symptoms secondary to the development of maculopathy. There are currently no data regarding the prevalence of this condition among poppers users. The aim of this study was to quantify the presence of visual symptoms among poppers users from a global cohort. The Global Drug Survey (GDS) conducts annual anonymous online surveys of drug and alcohol use. Within the 2012 GDS, questions were inserted regarding the presence of visual symptoms in poppers users. The GDS received a total of 21 575 valid responses, with a total of 17 479 from the UK, Australia, USA and Eurozone. Within these areas, 5152 (29.5%) had used poppers within their lifetime and 1322 (7.6%) within the previous year. Of the 'last year' users, when asked the question: 'Do you think poppers use has affected your eyesight?', 29 (2.2%) people responded 'yes', 130 (10.0%) responded 'maybe' and 1146 (87.8%) responded 'no (17 people did not answer). Both multiple choice and free-text responses regarding the nature of visual symptoms correlated with the central visual disturbance that would be expected from maculopathy. There was significant increased symptom prevalence with age (likelihood ratio (χ 2 )=19.0; ppoppers users have visual symptoms. Clinical correlation is required to determine whether these reported symptoms are due to poppers associated maculopathy, or an alternative cause.

To investigate the change in the prevalence of dental erosion, over time, by a review of the data from the published national dental surveys of young people in the UK. A subsidiary objective was to investigate the relationship between erosion and possible associated risk factors. The review was based on cross-sectional prevalence studies incorporating a clinical dental examination and structured interviews. The data were collated from the 1993 UK childrens' dental health survey and the dental report of the two National Diet and Nutrition Surveys (NDNS) of children aged 1(1/2)-4(1/2) in 1992/3 and 4-18 years in 1996/7. The criteria used for data collection were comparable between the three different studies. Comparing the data from the different studies, the prevalence of erosion was seen to increase from the time of the childrens' dental health survey in 1993 and the NDNS study of 4-18-year-olds in 1996/7. There was a trend towards a higher prevalence of erosion in children aged between 3(1/2) and 4(1/2) and in those who consumed carbonated drinks on most days compared with toddlers consuming these drinks less often. Drinks overnight were associated with an increased prevalence of erosion. More 4-6-year-olds with reported symptoms of gastro-oesophageal reflux had erosion compared with symptom-free children. On multivariate analysis, the strongest independent association with erosion was geography, with children living in the North having twice the odds of having erosion compared with those in London and the South-east. Comparing prevalence data from cross-sectional national studies indicates that dental erosion increases between different age cohorts of young people over time. Dietary associations with erosion are present but weak. Similarly, there is an association apparent between erosion, symptoms of gastro-oesophageal reflux and socio-demographic variables such as region of domicile, social class, and receipt of social benefits.

Tic disorders are common causes of morbidity in Israel but their prevalence in this country needs further study. To assess the prevalence of mental disorders in Israeli youth including tic disorders, as part of the Israel Survey of Mental Health among Adolescents (ISMEHA). The ISMEHA was conducted in a representative sample of 957 adolescents aged 14-17 and their mothers during 2004-2005. We interviewed the adolescents and their mothers in their homes and collected demographic information about the use of services. We also administered a psychiatric interview, the Development and Well-Being Assessment inventory (DAWBA), which included a question on tic disorder. The prevalence of tic disorders was calculated based on the adolescents' and maternal reports. The relationships among demographic data, comorbidity rates, help-seeking behaviors and tic disorder are presented. The prevalence of tics was 1.3% according to maternal reports and 4.4% according to adolescents' reports. The prevalence correlated with externalizing disorders and learning disabilities. A higher prevalence of tics was found in the Arab population compared with Jewish adolescents. The prevalence of tic disorders in Israel, as measured by a direct question in this epidemiological study, and associated comorbidities concurs with previous reports. The complexities of prevalence estimations, comorbidities, demographic correlates, and help-seeking behaviors are discussed.

Due to rapid population aging and a tidal wave of dementia, dementia has become an urgent public health issue in China. Few large-scale surveys on dementia have been conducted in China and little was known about the magnitude of dysfunction and disability caused by dementia. In this study, using national sample survey data, we aimed to describe the prevalence rate of dementia-associated disability, its associated factors, and daily activities and social functions of people with dementia-associated disability in Chinese older adults. We used the second China National Sample Survey on Disability, comprising 2,526,145 persons from 771,797 households. Identification for dementia was based on consensus manuals. Standard weighting procedures were used to construct sample weights considering the multistage stratified cluster sampling survey scheme. Population weighted numbers, weighted prevalence, and the odd ratios (ORs) were calculated. The prevalence rate of dementia-associated disability was 4.64% (95% CI: 4.26-5.01) and it accounted for 41.03% of mental disability among Chinese older adults. Urban residence (OR: 1.33 [1.12-1.57]), older age (80+ years) (OR: 4.12 [3.38-.03]), illiteracy (OR: 1.79 [1.27-2.53]), and currently not married (OR: 1.15 [1.00-1.32]) were associated with increased risk of dementia-associated disability. Compared with those with mental disability of other causes and those with other types of disabilities, older adults with dementia-asscoiated disability were more likely to have severe or extreme difficulty in daily activities and social functions. Countermeasures are warranted to obtain a more precise overview of dementia in China, and strategies on enhancing early identification, treatment, and rehabilitation should be developed for people with dementia.

Consistently low prevalence of syphilis among female sex workers in Jinan, China: findings from two consecutive respondent driven sampling surveys.

Directory of Open Access Journals (Sweden)

Meizhen Liao

Full Text Available BACKGROUND: Routine surveillance using convenient sampling found low prevalence of HIV and syphilis among female sex workers in China. Two consecutive surveys using respondent driven sampling were conducted in 2008 and 2009 to examine the prevalence of HIV and syphilis among female sex workers in Jinan, China. METHODS: A face-to-face interview was conducted to collect demographic, behavioral and service utilization information using a structured questionnaire. Blood samples were drawn for serological tests of HIV-1 antibody and syphilis antibody. Respondent Driven Sampling Analysis Tool was used to generate population level estimates. RESULTS: In 2008 and in 2009, 363 and 432 subjects were recruited and surveyed respectively. Prevalence of syphilis was 2.8% in 2008 and 2.2% in 2009, while no HIV case was found in both years. Results are comparable to those from routine sentinel surveillance system in the city. Only 60.8% subjects in 2008 and 48.3% in 2009 reported a consistent condom use with clients during the past month. Over 50% subjects had not been covered by any HIV-related services in the past year, with only 15.6% subjects in 2008 and 13.1% in 2009 ever tested for HIV. CONCLUSIONS: Despite the low prevalence of syphilis and HIV, risk behaviors are common. Targeted interventions to promote the safe sex and utilization of existing intervention services are still needed to keep the epidemic from growing.

High blood pressure (BP) is a major risk factor for cardiovascular disease. The urgency of the problem was underlined by the World Health Organization (WHO) Global Action Plan for the prevention and control of noncommunicable diseases, which recommends a 25% relative reduction in the prevalence of raised BP by 2020. A surveillance system represents a useful tool to monitor BP in the general population. Since 1980s, the National Institute of Health has conducted several surveys of the adult general population, measuring cardiovascular risk factors by standardized procedures and methods. To describe mean BP levels and high BP prevalence from 1978 to 2012 by sex and quinquennia of age. Data were derived from the following three studies: (i) Risk Factors and Life Expectancy (RIFLE), conducted between 1978 and 2002 in 13 Italian regions (>70,000 persons); (ii) Osservatorio Epidemiologico Cardiovascolare (OEC), conducted between 1998-2002 in the general population from all Italian regions (>9000 persons); and (iii) Osservatorio Epidemiologico Cardiovascolare/Health Examination Survey (OEC/HES), conducted between 2008-2012 in the general population from all Italian regions (>9000 persons). A significant decrease in mean systolic and diastolic BP levels and prevalence of high BP from 1978 to 2012 was observed both in men and women. BP and high BP increased by age classes in all considered periods. BP awareness and control also improved. Our data suggest that BP control could be achieved by 2020, as recommended by WHO.

Full Text Available Introduction: Due to an insufficient knowledge of the real asthma prevalence rate among children and adults in Belarus, we conducted a population-based respiratory health survey. Aim of the study: The study aimed at estimating the prevalence rate of asthma and major respiratory symptoms among students of the Grodno Region (Western Belarus. Material and methods: The cross-sectional study was conducted in 2014 and included 833 students aged 20-40 (young adults. Physician-diagnosed respiratory diseases and symptoms were ascertained using electronic version of the ISAAC questionnaire (web LimeSurvey. Results: The prevalence of asthma was 2.88% (physician-diagnosed. The obstructive (asthmatic bronchitis (without established diagnosis of asthma was found in 5.04% of the respondents. A chronic respiratory symptom occurring in the past 12 months and suggestive of asthma included attacks of dyspnea at rest, cough (5.88% or in previous periods (8.88%, and wheezing in the chest (one of the most characteristic symptoms of asthma - 8.04%, which may indicate a higher prevalence of asthma among patients. Wheezing and wheeze without diagnosed asthma, colds or infections were reported in a small number of cases (about 1.0%. 32 respondents (3.84% can be attributed to the group of risk for asthma due to the presence of specific respiratory symptoms. Conclusions: The findings show a low prevalence of physician-diagnosed asthma among students of Western Belarus. Relatively low prevalence of allergic disorders among respondents of Belarus suggest underdiagnosis of allergic diseases, in particular of asthma. Presumably, cases of asthma might be diagnosed as spastic bronchitis, “obstructive bronchitis”, “asthmatic bronchitis”, a traditional label for clinical manifestation of asthma in medical practice in the region.

Recent research conducted in high-income countries suggests psychotic experiences are common in the general population, but evidence from low- and middle-income countries (LMIC) remains limited. Sri Lanka is a LMIC affected by three decades of civil conflict and, in 2004, a devastating tsunami. This study aimed to investigate the prevalence of psychotic experiences in a general population sample in Sri Lanka and associations with conflict- and tsunami-related trauma. This is a first National Mental Health Survey conducted in Sri Lanka. A cross-sectional, multi-stage, cluster sampling design was used to estimate the prevalence of psychotic symptoms. Data on socio-demographic characteristics, conflict- and tsunami-related trauma, and psychotic experiences were collected using culturally validated measures in a sample of 5927 participants. The weighted prevalence of psychotic symptoms was 9.7%. Exposure to one or more conflict-related events (adj. OR 1.79, 95% CI 1.40-2.31, pconflict (adj. OR, 1.83, 95% CI 1.42-2.37, pconflicts and natural disasters may be important socio-environmental factors in the development of psychotic experiences. Copyright © 2016 Elsevier B.V.

The WHO definition of trachomatous trichiasis (TT) is "at least one eyelash touching the globe, or evidence of recent epilation of in-turned eyelashes", reflecting the fact that epilation is used as a self-management tool for TT. In Fiji's Western Division, a high TT prevalence (8.7% in those aged ≥15 years) was reported in a 2012 survey, yet a 2013 survey found no TT and Fijian ophthalmologists rarely see TT cases. Local anecdote suggests that eyelash epilation is a common behaviour, even in the absence of trichiasis. Epilators may have been identified as TT cases in previous surveys. We used a preliminary focus group to design an interview questionnaire, and subsequently conducted a population-based prevalence survey to estimate the prevalence of epilation in the absence of trichiasis, and factors associated with this behaviour, in the Western Division of Fiji. We sampled 695 individuals aged ≥15 years from a total of 457 households in 23 villages. 125 participants (18%) reported epilating their eyelashes at least once within the past year. Photographs were obtained of the eyes of 121/125 (97%) individuals who epilated, and subsequent analysis by an experienced trachoma grader found no cases of trachomatous conjunctival scarring or trichiasis. The age- and sex- adjusted prevalence of epilation in those aged ≥15 years was 8.6% (95% CI 5.7-11.3%). iTaukei ethnicity, female gender, and a higher frequency of drinking kava root were independently associated with epilation. Epilation occurs in this population in the absence of trichiasis, with sufficient frequency to have markedly inflated previous estimates of local TT prevalence. Individuals with epilated eyelashes should be confirmed as having epilated in-turned eyelashes in an eye with scarring of the conjunctiva before being counted as cases of TT.

With an overall adult HIV prevalence of 15.3%, Namibia is facing one of the largest HIV epidemics in Africa. Young people aged 20 to 34 years constitute one of the groups at highest risk of HIV infection in Namibia. However, little is known about the impact of HIV on this group and its access to healthcare. The purpose of this study was to estimate HIV prevalence, to assess the knowledge of and attitudes towards HIV/AIDS, and to assess access to healthcare among university students in Namibia. We assessed HIV/AIDS knowledge and attitudes, HIV prevalence and access to healthcare among students at the Polytechnic of Namibia and the University of Namibia. HIV prevalence was tested through anonymous oral fluid-based tests. Half (n = 2790/5568) of the university students and 45% (n = 2807/6302) of the Polytechnic students participated in the knowledge and attitudes surveys. HIV/AIDS knowledge was reasonable, except for misperceptions about transmission. Awareness of one's own HIV status and risks was low. In all, 55% (n = 3055/5568) of university students and 58% (n = 3680/6302) of Polytechnic students participated in the HIV prevalence survey; 54 (1.8%) university students and 103 (2.8%) Polytechnic students tested HIV positive. Campus clinics were not the major providers of healthcare to the students. Meaningful strategies addressing the gap between knowledge, attitude and young people's perception of risk of HIV acquisition should be implemented. HIV prevalence among Namibian university students appears relatively low. Voluntary counselling and testing should be stimulated. Efforts should be made to increase access to healthcare through the campus clinics.

Objective was to determine the prevalence and regional distribution ofsickle cell disease in Saudi children. A sample size of 45,682 children andadolescents from newborn to 19 years of age was selected by multistage randomprobability sampling of the Saudi households from each of the 13 regions ofthe country. The study is cross-sectional, community based and conducted over2 years from 2004 to 2005. Data including history and clinical examinationwere collected with house-to-house survey of all selected households. Datamanagement and analysis was carried out at King Saud University, Riyadh,Saudi Arabia. Sickle cell disease was detected in 108 of 45,682 children andadolescents with a prevalence of 24 per 10,000. The regional distribution ofsickle cell disease showed eastern region dominance with a prevalence of 145per 10,000, followed by the southern region with a prevalence of 24 per10,000, western region 12 per 10,000and central region with 6 per 10,000. Nocases were found in the northern region. The male to female ratio wasapproximately 1:1. The results of this national wide community-based surveyshow a high prevalence of sickle cell disease. In the community and thedisease is more common in eastern and southern regions of the country.National or regional newborn screening programs for sickle cell disease usinghematological tests should be planned. This study shows that the populationat risk has an uneven geographical distribution. For this reason, selectiverather than universal neonatal screening is likely to be more appropriate inthe country.

Full Text Available Abstract Background Current US surveillance data provide estimates of diabetes using laboratory tests at the national level as well as self-reported data at the state level. Self-reported diabetes prevalence may be biased because respondents may not be aware of their risk status. Our objective was to estimate the prevalence of diagnosed and undiagnosed diabetes by state. Methods We estimated undiagnosed diabetes prevalence as a function of a set of health system and sociodemographic variables using a logistic regression in the National Health and Nutrition Examination Survey (2003-2006. We applied this relationship to identical variables from the Behavioral Risk Factor Surveillance System (2003-2007 to estimate state-level prevalence of undiagnosed diabetes by age group and sex. We assumed that those who report being diagnosed with diabetes in both surveys are truly diabetic. Results The prevalence of diabetes in the U.S. was 13.7% among men and 11.7% among women ≥ 30 years. Age-standardized diabetes prevalence was highest in Mississippi, West Virginia, Louisiana, Texas, South Carolina, Alabama, and Georgia (15.8 to 16.6% for men and 12.4 to 14.8% for women. Vermont, Minnesota, Montana, and Colorado had the lowest prevalence (11.0 to 12.2% for men and 7.3 to 8.4% for women. Men in all states had higher diabetes prevalence than women. The absolute prevalence of undiagnosed diabetes, as a percent of total population, was highest in New Mexico, Texas, Florida, and California (3.5 to 3.7 percentage points and lowest in Montana, Oklahoma, Oregon, Alaska, Vermont, Utah, Washington, and Hawaii (2.1 to 3 percentage points. Among those with no established diabetes diagnosis, being obese, being Hispanic, not having insurance and being ≥ 60 years old were significantly associated with a higher risk of having undiagnosed diabetes. Conclusion Diabetes prevalence is highest in the Southern and Appalachian states and lowest in the Midwest and the Northeast

To examine trends in leisure time physical activity and inactivity in Australians aged 15 years or older from 1989 to 2011. We used data from six Australian National Health Surveys conducted from 1989/90 to 2011/12 in which physical activity was assessed using comparable questions. Analyses examined trends in the prevalence of sufficient physical activity (≥150 minutes/week moderate-to-vigorous physical activity) and of inactivity (benefits from sufficient physical activity. Maintenance of consistent physical activity questions in future National Health Surveys will facilitate long term tracking of physical activity levels in the Australian population. © 2017 The Authors.

Full Text Available BACKGROUND: Cameroon is known to be endemic with trachoma. To appreciate the burden of the disease and facilitate the national planning of trachoma control in the integrated control program for the neglected tropical diseases, an epidemiological mapping of trachoma was conducted in the Far North region in 2010-11. METHODOLOGY: A cross-sectional, cluster random sampling survey was carried out. The survey focused on two target populations: children aged 1 to 9 years for the prevalence of active trachoma and those aged 15 and over for the prevalence of trichiasis (TT. The sample frame was an exhaustive list of villages and neighborhoods of Health Districts (HDs. The World Health Organization simplified trachoma grading system was used for the recognition and registration of cases of trachoma. PRINCIPAL FINDINGS: 48,844 children aged 1 to 9 years and 41,533 people aged 15 and over were examined. In children aged 1-9 years, the overall prevalence of trachomatous inflammation-follicular (TF was 11.2% (95% confidence intervals (CI: 11.0-11.5%. More girls were affected than boys (p = 0.003. Thirteen (13 of 27 HDs in the region showed TF prevalence of ≥10%. The overall TT prevalence was 1.0% (95% CI: 0.9-1.1%. There were estimated 17193 (95% CI: 12576-25860 TT cases in the region. The prevalence of blindness was 0.04% (95% CI: 0.03-0.07% and visual impairment was 0.09% (95% CI: 0.07-0.13%. CONCLUSIONS/SIGNIFICANCE: The survey confirmed that trachoma is a public health problem in the Far North region with 13 HDs qualified for district-level mass drug administration with azithromycin. It provided a foundation for the national program to plan and implement the SAFE strategy in the region. Effort must be made to find resources to provide the surgical operations to the 17193 TT cases and prevent them from becoming blind.

The overall aim of this study was to describe preventive interventions among persons with pressure ulcer (PU) in three nationwide PU prevalence surveys in Sweden. A cross-sectional research design was used; more than 70 000 persons from different hospitals and nursing homes participated in the three prevalence surveys conducted in March 2011, October 2011 and March 2012. The methodology used was that recommended by the European Pressure Ulcers Advisory Panel. The overall prevalence of PU categories I-IV in hospitals was 16.6%, 14.4% and 16.1%, respectively. Corresponding figures for nursing homes were 14.5%, 14.2% and 11.8%, respectively. Heel protection/floating heels and sliding sheets were more frequently planned for persons with PU category I. Despite the three prevalence studies that have showed high prevalence of PU the use of preventing interventions is still not on an acceptable level. Heel protection/floating heels and sliding sheets were more frequently planned for persons with PUs, and individual-planned repositioning also increased. However, when persons already have a PU they should all have pressure-reducing preventive interventions to prevent the development of more PUs. Preventing PUs presents a challenge even when facilities have prevention programmes. A PU prevention programme requires an enthusiastic leader who will maintain the team's focus and direction for all staff involved in patient care. © 2013 John Wiley & Sons, Ltd.

Full Text Available Workaholism has become an increasingly popular area for empirical study. However, most studies examining the prevalence of workaholism have used non-representative samples and measures with poorly defined cut-off scores. To overcome these methodological limitations, a nationally representative survey among employees in Norway (N = 1,124 was conducted. Questions relating to gender, age, marital status, caretaker responsibility for children, percentage of full-time equivalent, and educational level were asked. Workaholism was assessed by the use of a psychometrically validated instrument (i.e., Bergen Work Addiction Scale. Personality was assessed using the Mini-International Personality Item Pool. Results showed that the prevalence of workaholism was 8.3% (95% CI  = 6.7-9.9%. An adjusted logistic regression analysis showed that workaholism was negatively related to age and positively related to the personality dimensions agreeableness, neuroticism, and intellect/imagination. Implications for these findings are discussed.

Background: Chronic kidney disease is an important risk factor for death and cardiovascular-related morbidity, but estimates to date of its prevalence in Canada have generally been extrapolated from the prevalence of end-stage renal disease. We used direct measures of kidney function collected from a nationally representative survey population to estimate the prevalence of chronic kidney disease among Canadian adults. Methods: We examined data for 3689 adult participants of cycle 1 of the Canadian Health Measures Survey (2007–2009) for the presence of chronic kidney disease. We also calculated the age-standardized prevalence of cardiovascular risk factors by chronic kidney disease group. We cross-tabulated the estimated glomerular filtration rate (eGFR) with albuminuria status. Results: The prevalence of chronic kidney disease during the period 2007–2009 was 12.5%, representing about 3 million Canadian adults. The estimated prevalence of stage 3–5 disease was 3.1% (0.73 million adults) and albuminuria 10.3% (2.4 million adults). The prevalence of diabetes, hypertension and hypertriglyceridemia were all significantly higher among adults with chronic kidney disease than among those without it. The prevalence of albuminuria was high, even among those whose eGFR was 90 mL/min per 1.73 m2 or greater (10.1%) and those without diabetes or hypertension (9.3%). Awareness of kidney dysfunction among adults with stage 3–5 chronic kidney disease was low (12.0%). Interpretation: The prevalence of kidney dysfunction was substantial in the survey population, including individuals without hypertension or diabetes, conditions most likely to prompt screening for kidney dysfunction. These findings highlight the potential for missed opportunities for early intervention and secondary prevention of chronic kidney disease. PMID:23649413

Population surveys are frequently used to assess prevalence, correlates and health benefits of physical activity. However, nonsampling errors, such as question order effects, in surveys may lead to imprecision in self reported physical activity. This study examined the impact of modified question order in a commonly used physical activity questionnaire on the prevalence of sufficient physical activity. Data were obtained from a telephone survey of adults living in Queensland, Australia. A total of 1243 adults participated in the computer-assisted telephone interview (CATI) survey conducted in July 2008 which included the Active Australia Questionnaire (AAQ) presented in traditional or modified order. Binary logistic regression analyses was used to examine relationships between question order and physical activity outcomes. Significant relationships were found between question order and sufficient activity, recreational walking, moderate activity, vigorous activity, and total activity. Respondents who received the AAQ in modified order were more likely to be categorized as sufficiently active (OR = 1.28, 95% CI 1.01-1.60). This study highlights the importance of question order on estimates of self reported physical activity. This study has shown that changes in question order can lead to an increase in the proportion of participants classified as sufficiently active.

The number of patients with primary hyperparathyroidism (PHP) seen at theAsir Central Hospital (ACH) is remarkably low. This observation has raisedthe question of whether there is a low prevalence of PHP in the Asir region,whether it is underdiagnosed, or perhaps a combination of other both factors.A survey of 15 hospitals in the Asir region was conducted for the cases ofPHP. All case notes of the patients with PHP are seen at ACH were reviewed.Also a sample of patients seen at ACH was chosen randomly. The charts ofthose found to have hypercalcemia were reviewed for the inclusion of PHP inthe diagnostic work-up. Only 13 patients with PHP were discovered. The eightpatients with PHP seen at ACH had advanced bone manifestations and seven ofthem had renal manifestations. Hypercalcemia was found in 39 out of 655patients seen at ACH. None of these had been investigated for PHP. The numberof patients with PHP seen in hospitals in the Asir region is very low.Underdiagnosis seems to be an important factor. Therefore, it is felt thatthere is a need for greater awareness of disease in the region. Furthermore,there is a need for national survey to measure the prevalence of PHP in SaudiArabia. (author)

We conducted a national survey among medical students in China to estimate the prevalence of depressive symptoms and explore associated risk factors based on an established questionnaire composed of demographic information, life events in the past four weeks before survey, and the validated Chinese version of the 21-item Beck's Depression Inventory (BDI). The mean age of enrolled 9010 students was 20.7 (standard deviation: 1.6) years. BDI scores indicated that 19.9% had depressive symptoms based on the cut-off score of 14. Socioeconomic factors and student characteristics such as male sex, low monthly income per capita, father's poor education background, and higher year of study were associated with higher prevalence of depressive symptoms among medical students. Students who studied in comprehensive universities were more likely to have depressive symptoms compared with those from medical universities. Habitual smoking and alcohol drinking, sleep deprivation, and hospitalization or medication for one week or more in the last four weeks also predisposed students to higher risk of depressive symptoms. Our results indicate that depressive symptoms are becoming a highly prevalent health problem among Chinese medical students. Primary and secondary prevention should be prioritized to tackle this issue based on potential risk factors.

A national survey of the prevalence of schistosomiasis and soil transmitted helminths in Malaŵi

Full Text Available Abstract Background Past estimates have put the prevalence of schistosomiasis between 40% and 50% in the Malawi population overall based on studies undertaken ten years or more ago. More recent surveys in known high risk areas find similar levels. However control measures, changing ecology and migration may have led to changes in the prevalence of schistosomiasis in different parts of Malawi. A national schistosomiasis and soil-transmitted helminth (STH survey was undertaken to measure the distribution, prevalence and intensity of infection in November 2002. Methods A school was selected randomly from a random sample of 30 Traditional Authorities stratified by six distinct ecological zones, and 1,664 year 3 pupils (9–10 year olds were questioned about recent illnesses and "red urine". Samples of urine and faeces were examined for the presence of eggs using the standard Kato-Katz technique for soil-transmitted helminths and intestinal schistosomiasis and urine samples using the filtration technique for Schistosoma haematobium. Results The prevalence of Schistosoma mansoni is 0.4% (95% CI 0–1.3%, S. haematobium 6.9% (95% CI 1.9 – 11.9%, hookworm 1.3% (95% CI 0.4–2.3%, Ascariasis 0.5% (95% CI 0.1–1.0% and trichuriasis 0% in year 3 pupils (modal age 10 years of age. Intensity of infection is low for all infections except for 2.5% who have high intensity S. haematobium infection. The "red urine" question is 67% sensitive and 80% specific for positive S. haematobium microscopy. Conclusions The reduction in prevalences may be real as a result of recent control measures, or false if historical results were based on surveys of high risk populations. Another explanation is that this survey used an unrepresentative sample of schools. Detailed analysis suggests this is unlikely. Recommendations include the use of a 30% positive threshold for the "red urine" screening question to be used in schoolchildren in high prevalence areas. This survey

Previously considered as a disease of the affluent, west or urban people and not of public health importance, diabetes mellitus is increasingly becoming a significant cause of morbidity and mortality in sub-Saharan Africa. However, population-based data to inform prevention, treatment and control are lacking. Using the WHO STEPwise approach to chronic disease risk factor surveillance, a population-based, nationwide cross-sectional survey was conducted between July and September 2009 on participants aged 25-64 years. A multi-stage cluster sample design and weighting were used to produce a national representative data for that age range. Detailed findings on the magnitude of diabetes mellitus and impaired fasting blood glucose are presented in this paper. Fasting blood glucose measurement was conducted on 3056 participants (70.2% females, 87.9% from rural areas). The age- sex standardised population-based mean fasting blood glucose was 4.3 mmol/L (95% CI 4.1-4.4 mmol/L) with no significant differences by age, sex and location (urban/rural). The overall prevalence of impaired fasting blood glucose was 4.2% (95% CI 3.0%-5.4%). Prevalence of impaired blood glucose was higher in men than in women, 5.7% (95% CI 3.9%-7.5%) vs 2.7% (95% CI 1.6%- 3.8%), p prevalence of raised fasting blood glucose or currently on medication for diabetes was 5.6% (95% CI 2.6%- 8.5%). Although the prevalence of diabetes was higher in men than women, 6.5% (95% CI 2.6%-10.3%) vs 4.7% (95% CI 2.4%-7.0%), in rural than urban, 5.4% (95% CI 2.4%-8.4%) vs 4.4% (95% CI 2.8%-5.9%) and in males in rural than males in urban, 6.9% (95% CI 2.8%-11.0%) vs 3.2% (95% CI 0.1%-6.3%), the differences were not statistically significant, p > 0.05. Compared to previous estimates, prevalence of diabetes increased from prevalence of impaired fasting blood glucose and diabetes mellitus call for the implementation of primary healthcare approaches such as the WHO package for essential non-communicable diseases

This paper describes an integrated detection system that has been developed to conduct radiological surveys of sites suspected of contamination of materials such as depleted uranium. This system utilizes cerium activated lanthanum bromide and thallium activated sodium iodide gamma detectors and can be easily adapted to include units for detecting neutrons. The detection system includes software controlling the collection of radiological spectra and GPS data. Two different platforms are described for conducting surveys, a modified zero turn radius (ZTR) mower and a three-wheeled cart that is manually pushed. The detection system software controlling data collection has components that facilitate completing a grid-less survey on user specified spacings. Another package confirms that all data quality activities (calibrations, etc.) are conducted prior to beginning the survey and also reviews data to identify areas that have been missed for which data quality falls below user designated parameters. Advanced digital signal processing algorithms are used to enhance the interpretation of spectra for conducting background subtractions and for mapping. Data from radiation detection instruments and GPS antennae are merged and made compatible with mapping using Geosoft Oasis montaj software. A summary of system performance during field-testing is included in the paper. This includes survey rate, detection limits, duty cycle, supporting ancillary equipment/material, and manpower requirements. The rate of false positives and false negatives is discussed with the benefits of surveys conducted using synergetic detection systems such as electromagnetic induction imaging. (authors)

The global burden of conduct disorder is a major public health concern. Although there are different reports on the prevalence of conduct disorder in different Middle Eastern countries, to date, no research has reviewed them. Therefore, we aimed to conduct a systematic review and meta-analysis on the literature and present the prevalence of conduct disorder among children and adolescents in Middle Eastern countries. Those cross-sectional studies with any type of random or non-random sampling, which described the prevalence of conduct disorder prior to age of 18, for at least one gender in the general or school-based populations who resided in Middle Eastern countries were included in this review. The scientific databases of PubMed, Scopus, Google Scholar, Index Medicus for the Eastern Mediterranean Region (IMEMR), Islamic World Science Citation Center (ISC), and Grey Literature including conference proceedings, and hand searching of key journals were searched from 1995 to the end of 2014. Two reviewers assessed the quality of the included studies independently and extracted the relevant data. This review provided a picture of different frequencies of conduct disorder in Middle Eastern countries and analyzed the sources of heterogeneity. PROSPERO CRD42014014996.

Abstract. In stable transmission areas, malaria is the leading cause of anemia in children. Anemia in children is proposed as an added sensitive indicator for community changes in malaria prevalence. We report short-term temporal variations of malaria and anemia prevalence in rural Malawian children. Data from five repeated cross-sectional surveys conducted over 1 year in rural communities in Chikwawa District, Malawi, were analyzed. Different households were sampled per survey; all children, 6–59 months, in sampled household were tested for malaria parasitemia and hemoglobin levels using malaria rapid diagnostic tests (mRDT) and Hemocue 301, respectively. Malaria symptoms, recent treatment (2 weeks) for malaria, anthropometric measurements, and sociodemographic details were recorded. In total, 894 children were included from 1,377 households. The prevalences of mRDT positive and anemia (Hb anemia and parasite prevalence varied differently. Overall, unadjusted and adjusted relative risks of anemia in mRDT-positive children were 1.31 (95% CI: 1.09–1.57) and 1.36 (1.13–1.63), respectively. Changes in anemia prevalence differed with short-term changes in malaria prevalence, although malaria is an important factor in anemia. PMID:28820717

A nationwide survey was conducted to obtain an estimate of Chagas disease prevalence among pregnant women in Ecuador. As part of a national probability sample, 5,420 women seeking care for delivery or miscarriage at 15 healthcare facilities were recruited into the study. A small minority of participants reported knowing about Chagas disease or recognized the vector. A national seroprevalence of 0.1% (95% confidence interval [95% CI] = 0.0–0.2%) was found; cases were concentrated in the coastal region (seroprevalence = 0.2%; 95% CI = 0.0–0.4%). No cases of transmission to neonates were identified in the sample. Seropositive participants were referred to the National Chagas Program for evaluation and treatment. Additional studies are necessary to determine if areas of higher prevalence exist in well-known endemic provinces and guide the development of a national strategy for elimination of mother-to-child transmission of Chagas disease in Ecuador.

The care-associated infections (HAI) are the most serious complication associated with medical care. They are the cause of diseases for patients and economic damage to public health. The University "Federico II" of Naples decided to monitor the HAI, repeating the prevalence survey conducted earlier in 2011 in order to analyze the phenomenon of infection and to evaluate the possible correlation with risk factors. The Survey was conducted according to ECDC criteria. Considered that the study carried out in 2011 was conducted following the same methodology, to compare the results of the year 2012 the prevalence rates of both years were standardized. For the year 2012, the number of patients enrolled in the study and stratification of patients by age and sex were similar to data collected in 2011. It was very interesting to find the prevalence of HAI standardized reduced in 2012 compared to 2011. As a matter of fact, in fact, that the standardized prevalence of HAI for the year 2012 was 3.1%, one percentage point lower than in 2011 (4.4%). The practical training and direct regarded as the most appropriate approach in order to make health professionals aware in the field of health care-associated infections, as well as the system of selfcontrol peripheral for the correct application of the procedures, as well as epidemiological surveillance active, measured through rates of incidence, at the same time allow the monitoring of the phenomenon is infectious and the application of corrective measures that prevent its onset. The choice to make again an epidemiological study of prevalence with the same methodology ensures, in fact, two advantages: the comparability of the data, both at intra-company both at regional, national and international evaluation of the effectiveness of corrective actions.

Prevalence of sexual abuse among children with conduct disorder: a systematic review.

Science.gov (United States)

Maniglio, Roberto

2014-09-01

Many clinicians and researchers have speculated that child sexual abuse and conduct disorder co-occur frequently, yet no systematic reviews of literature have specifically addressed both these conditions. To estimate the prevalence of sexual abuse among children with conduct disorder, the pertinent literature was systematically reviewed. Ten databases were searched, supplemented with hand search of reference lists from retrieved papers. Blind assessments of study eligibility and quality were conducted by two independent researchers. Disagreements were resolved by consensus. Twenty-three studies meeting minimum quality criteria that were enough to insure objectivity and not to invalidate results and including 7,256 participants with either conduct disorder or child sexual abuse were examined. The prevalence of child sexual abuse among participants with conduct disorder was 27 %; however, such figure might be underestimated due to selection, sampling, and recall biases; poor assessment methods; and narrow definitions of abuse in included studies. Participants with conduct disorder, compared with healthy individuals, reported higher rates of child sexual abuse. However, compared with other psychiatric populations, they reported similar or lower rates. There was also some evidence suggesting that children with conduct disorder might be more likely to report child physical abuse. Female participants with conduct disorder, compared with males, were significantly more likely to report child sexual abuse. Youths with conduct disorder are at risk of being (or having been) sexually abused, although such risk seems to be neither more specific to nor stronger for these individuals, compared with people with other psychiatric disorders.

We aimed to determine the prevalence of, and factors associated with, breastfeeding initiation in Canadian Inuit. We used data from the Nunavut Inuit Child Health Survey, a population-based, cross-sectional survey conducted in the Canadian territory of Nunavut. Inuit children aged 3-5 years in 2007 or 2008 were randomly selected for the survey. Select household, maternal, infant and community characteristics were collected from the child's primary caregiver and entered into logistic regression models as potential predictors of breastfeeding initiation. Analyses were repeated in a subgroup of caregiver reports from biological mothers. The reported prevalence of breastfeeding initiation was 67.6% (95% CI 62.4-72.8) overall and 85.1% (95% CI 80.2-90.1) in a subgroup of caregiver reports from biological mothers. Adjusted prevalence odds ratios (pOR) indicate the primary caregiver was an important determinant of breastfeeding (adopted parent vs. biological mother: pOR = 0.03, 95% CI 0.01-0.07; other vs. biological mother: pOR = 0.33, 95% CI 0.14-0.74). Maternal smoking during pregnancy and having access to a community birthing facility were also potentially important, but not statistically significant (p > 0.05). In conclusion, data from the Nunavut Inuit Child Health Survey indicate breastfeeding is initiated for more than two-thirds of children, but rates are below the national average and this may be one of several pathways to poor health outcomes documented in many Inuit communities. Considered in the particular context of birthing facilities utilization and postnatal care arrangements in Inuit communities, these results suggest that increasing breastfeeding initiation will require health interventions that effectively engage all types of primary caregivers.

Malaria is endemic in 13 districts of Bangladesh. A baseline malaria prevalence survey across the endemic districts of Bangladesh was conducted in 2007, when the prevalence was reported around 39.7 per 1000 population. After two rounds of Global Fund to Fight AIDS, Tuberculosis and Malaria (GFATM)-funded intervention by the National Malaria Control Programme (NMCP) and a BRAC-led NGO consortium, a follow-up survey was conducted across the malaria-endemic districts of Bangladesh to measure the change in prevalence rate and in people's knowledge of malaria. The survey was carried out from August to November 2013 in 70 upazilas (sub-districts) of 13 malaria-endemic districts of Bangladesh, following the same multi-stage cluster sampling design and the same number of households enrolled during the baseline prevalence survey in 2007, to collect 9750 randomly selected blood samples. For on-the-spot diagnosis of malaria, a rapid diagnostic test was used. The household head or eldest person available was interviewed using a pre-coded structured questionnaire to collect data on the knowledge and awareness of malaria in the household. Based on a weighted calculation, the overall malaria prevalence was found to be 1.41 per 1000 population. The proportion of Plasmodium falciparum mono-infection was 77.78% while both Plasmodium vivax mono-infection and mixed infection of the two species were found to be 11.11%. Bandarban had the highest prevalence (6.67 per 1000 population). Knowledge of malaria signs, symptoms and mode of transmission were higher in the follow-up survey (97.26%) than the baseline survey. Use of bed nets for prevention of malaria was found to be high (90.15%) at respondent level. People's knowledge of selected parameters increased significantly during the follow-up survey compared to the baseline survey conducted in 2007. A reduced prevalence rate of malaria and increased level of knowledge were observed in the present malaria prevalence survey in Bangladesh.

Full Text Available Child undernutrition is a major public health concern in Ethiopia (stunting national prevalence: 44%; wasting: 10%, despite the overall improvement in child health status during the last decade. Hundreds of small-scale surveys are conducted in Ethiopia’s emergency pockets under ENCU’s supervision. We reviewed the evidence from small-scale surveys conducted between 2008 and 2013 with two objectives: to provide a summary estimate of wasting prevalence from emergency pockets and to examine reasons for variation in prevalence estimates. We created a dataset by combining data from the Complex Emergency Database, the Famine Early Warning System Network and the Armed Conflict Location Event Data. We conducted a meta-analysis of small-scale surveys using a random effects model with known within-study heterogeneity. The influence of survey covariates on estimated prevalence was investigated with meta-regression techniques. We included 158 surveys in the analysis. A high degree of heterogeneity among surveys was observed. The overall estimate of wasting prevalence was 10.6% (95% CI 9.8–11.4, with differences among regions and between residents and refugees. Meta-regression results showed that vaccination coverage, child mortality, diarrhea prevalence and food insecurity are significantly associated with wasting prevalence. Child care and displacement status were not. Aggregated analysis of small-scale surveys provides insights into the prevalence of wasting and factors explaining its variation. It can also guide survey planning towards areas with limited data availability.

A stratified probability sample survey of the British general population, aged 16 to 44 years, was conducted from 1999 to 2001 (N = 11,161) using face-to-face interviewing and computer-assisted self-interviewing. We used these data to estimate the population prevalence of masturbation, and to identify sociodemographic, sexual behavioral, and attitudinal factors associated with reporting this behavior. Seventy-three percent of men and 36.8% of women reported masturbating in the 4 weeks prior to interview (95% confidence interval 71.5%-74.4% and 35.4%-38.2%, respectively). A number of sociodemographic and behavioral factors were associated with reporting masturbation. Among both men and women, reporting masturbation increased with higher levels of education and social class and was more common among those reporting sexual function problems. For women, masturbation was more likely among those who reported more frequent vaginal sex in the last four weeks, a greater repertoire of sexual activity (such as reporting oral and anal sex), and more sexual partners in the last year. In contrast, the prevalence of masturbation was lower among men reporting more frequent vaginal sex. Both men and women reporting same-sex partner(s) were significantly more likely to report masturbation. Masturbation is a common sexual practice with significant variations in reporting between men and women.

There have been few cross-national studies of the prevalence of the frailty phenotype conducted among low or middle income countries. We aimed to study the variation in prevalence and correlates of frailty in rural and urban sites in Latin America, India, and China. Cross-sectional population-based catchment area surveys conducted in 8 urban and 4 rural catchment areas in 8 countries; Cuba, Dominican Republic, Puerto Rico, Venezuela, Peru, Mexico, China, and India. We assessed weight loss, exhaustion, slow walking speed, and low energy consumption, but not hand grip strength. Therefore, frailty phenotype was defined on 2 or more of 4 of the usual 5 criteria. We surveyed 17,031 adults aged 65 years and over. Overall frailty prevalence was 15.2% (95% confidence inteval 14.6%-15.7%). Prevalence was low in rural (5.4%) and urban China (9.1%) and varied between 12.6% and 21.5% in other sites. A similar pattern of variation was apparent after direct standardization for age and sex. Cross-site variation in prevalence of frailty indicators varied across the 4 indicators. Controlling for age, sex, and education, frailty was positively associated with older age, female sex, lower socioeconomic status, physical impairments, stroke, depression, dementia, disability and dependence, and high healthcare costs. There was substantial variation in the prevalence of frailty and its indicators across sites in Latin America, India, and China. Culture and other contextual factors may impact significantly on the assessment of frailty using questionnaire and physical performance-based measures, and achieving cross-cultural measurement invariance remains a challenge. A consistent pattern of correlates was identified, suggesting that in all sites, the frailty screen could identify older adults with multiple physical, mental, and cognitive morbidities, disability and needs for care, compounded by socioeconomic disadvantage and catastrophic healthcare spending.

Breastfeeding is recommended by international bodies as the only source of infant nutrition during the first 6 months of life. Sometimes infants prefer to nurse on one breast for no obvious reason (hereafter called infant's unexplained breast preference [IUBP]). IUBP might reduce the rate of exclusive breastfeeding. The prevalence of IUBP is unknown because most of the literature on IUBP so far has been anecdotal. This study's objective was to investigate the prevalence and characteristics of IUBP among healthy infants in Al-Ahsa, Saudi Arabia. We conducted a population-based, cross-sectional study between March and August 2013 in the Al-Ahsa area, Eastern Province, Saudi Arabia. Healthy infants who had been born at full term (≥37 weeks of gestation) and were 2-24 months of age were included. We distributed 600 self-administered surveys to mothers who attended vaccination clinics in nine primary healthcare centers. Of 478 mothers who responded to the survey, 121 (25.3%) reported unilateral breastfeeding. IUBP was the most common reason for unilateral breastfeeding, with a prevalence of 13.6% (65/478). IUBP developed at a median age of 1 month (range, 1 day-9 months) and was familial in 42.9% of cases. It was the only reason for formula feeding during the first 6 months of life in 18.5% of cases. IUBP is common, develops very early in life, and can be familial and a reason for formula feeding. However, these findings need to be confirmed in other studies of other populations.

Major depressive disorder (MDD) is the most prevalent mental disorder in the general population and has been associated with socioeconomic factors. Beijing has undergone significant socioeconomic changes in last decade, however no large-scale community epidemiological surveys of MDD have been conducted in Beijing since 2003. To determine the prevalence of MDD and its socio-demographic correlates in a representative household sample of the general population in Beijing, China. Data were collected from the 2010 representative household epidemiological survey of mental disorders in Beijing. The multistage cluster random sampling method was used to select qualified subjects in 18 districts and counties, and then face-to-face interviews were administered using the Chinese version of Structured Clinical Interview for DSM-IV-TR Axis I Disorders-Patient Edition (SCID-I/P) during November 1, 2010 to December 31, 2010. 19,874 registered permanent residents were randomly identified and 16,032 (response rate=80.7%) completed face-to-face interviews. The time-point and life-time prevalence rates of MDD were estimated to be 1.10% (95% CI: 0.94-1.26%) and 3.56% (95% CI: 3.27-3.85%) respectively. Significant differences were found in sex, age, location of residence, marital status, education, employment status, personal/family monthly income, perception of family environment and relationship with others, when comparing residents with MDD to those without MDD. Those who were female, aged 45 or above, reported low family income, or reported an "average" or "poor" family environment were associated with a higher risk of MDD. The prevalence of MDD reported in this survey is relatively lower than that in other western countries. Female sex, age older than 45, low family income, and poor family environment appear to be independent risk factors for MDD. Copyright © 2015 Elsevier B.V. All rights reserved.

To explore whether lower tuberculosis notification rates among women are due to a reduced access to health care, particularly diagnostic services, for women. Age- and sex-specific tuberculosis prevalence rates of smear-positive tuberculosis were obtained from tuberculosis prevalence surveys reported to the WHO or published in the literature. Age- and sex-specific notification rates from the same countries in 1996 were used. Prevalence data and notifications from 29 surveys in 14 countries were used. Notification rates varied strongly among countries, but the female/male ratio was below 1 and decreased with increasing age in almost all. The female/male (F/M) prevalence ratios were less than 0.5 in surveys in the South-East Asia and Western Pacific Region, and approximately 1 in the African Region. In most countries the F/M sex ratio in prevalent cases was similar or lower than that in notified cases, suggesting that F/M differences in notification rates may be largely due to epidemiological differences and not to differential access to health care. However, available data are limited as the prevalence surveys in Africa were carried out many years ago, and in Asia notification rates may be distorted by a large private sector with deficiencies in notification.

The health and wellbeing of midwives are important considerations for workforce retention and quality care. The occurrence and relationships among mental health conditions such as burnout and depression have received little attention. We investigated the prevalence of burnout, depression, anxiety and stress in Australian midwives. An online survey was conducted in September 2014. Participants were recruited through the Australian College of Midwives and professional networks. The survey sought personal and professional details. Standard measures included the Copenhagen Burnout Inventory (CBI) (Personal, Work and Client subscales), and Depression, Anxiety, and Stress Scale (DASS). The sample was collapsed into two groups according to DASS clinical cut-offs (normal/mild versus moderate/severe/extreme). Effect size statistics were calculated and judged according to Cohen's guidelines. One thousand thirty-seven surveys were received. Respondents were predominantly female (98%), with an average age of 46.43 years, and 16.51 years of practice. Using a CBI subscale cut-off score of 50 and above (moderate and higher), 64.9% (n = 643) reported personal burnout; 43.8% (n = 428) reported work-related burnout; and 10.4% (n = 102) reported client-related burnout. All burnout subscales were significantly correlated with depression, anxiety and stress, particularly personal and work-related burnout with Spearman's rho correlations ranging from .51 to .63 (p stress (22.1%) symptoms. Mann-Whitney U tests revealed significant differences between groups with depression (r = .43), anxiety (r = .41) and stress (r = 48) having a medium size effect on burnout. Prevalence of personal and work-related burnout in Australian midwives was high. The physical and psychological exhaustion associated with the different types of burnout were reflected in symptoms of depression, anxiety and stress symptoms. Further research is needed to support the personal well-being of

Full Text Available Background. Although binge drinking prevalence and correlates among young people have been extensively studied in the USA and Northern Europe, less is known for Southern Europe countries with relatively healthier drinking cultures. Objective. We aimed at analyzing prevalence and correlates of binge drinking in a representative sample of young adults in Italy. Methods. We conducted a cross-sectional survey among alcohol-consuming young adults. We carried out univariate and multivariate analyses to assess associations between recent binge drinking and candidate variables. Results. We selected 654 subjects, with 590 (mean age: 20.65 ± 1.90 meeting inclusion criteria. Prevalence for recent binge drinking was 38.0%, significantly higher for females than males. Multivariate analysis showed that high alcohol expectancies, large amount of money available during the weekend, interest for parties and discos, female gender, cannabis use, influence by peers, and electronic cigarettes smoking all were significantly associated with recent binge drinking, whereas living with parents appeared a significant protective factor. Conclusions. More than a third of young adults using alcohol are binge drinkers, and, in contrast with findings from Anglo-Saxon countries, females show higher risk as compared with males. These data suggest the increasing importance of primary and secondary prevention programmes for binge drinking.

A recent American Thoracic Society and European Respiratory Society joint Task Force report recommends using a lower limit of normal (LLN) of forced expiratory volume in one second/forced vital capacity as opposed to a fixed ratio of definitions of airflow obstruction based on post-bronchodilator spirometry is not known. Detailed written questionnaires, full pulmonary function tests (including pre- and post-bronchodilator flow-volume loops) and atopy testing were completed in 749 subjects recruited from a random population sample. The GOLD-defined, age-adjusted prevalence (95% confidence interval) for adults aged >or=40 yrs was 14.2 (11.0-17.0)% compared with an LLN-defined, age-adjusted, post-bronchodilator prevalence in the same group of 9.0 (6.7-11.3)%. The prevalence of chronic obstructive pulmonary disease varied markedly depending on the definition used. Further research using longitudinal rather than cross-sectional data will help decide the preferred approach in chronic obstructive pulmonary disease prevalence surveys.

In 2008, the global urban population surpassed the rural population and by 2050 more than 6 billion will be living in urban centres. A growing body of research has reported on poor health outcomes among the urban poor but not much is known about HIV prevalence among this group. A survey of nearly 3000 men and women was conducted in two Nairobi slums in Kenya between 2006 and 2007, where respondents were tested for HIV status. In addition, data from the 2008/2009 Kenya Demographic and Health Survey were used to compare HIV prevalence between slum residents and those living in other urban and rural areas. The results showed strong intra-urban differences. HIV was 12% among slum residents compared with 5% and 6% among non-slum urban and rural residents, respectively. Generally, men had lower HIV prevalence than women although in the slums the gap was narrower. Among women, sexual experience before the age of 15 compared with after 19 years was associated with 62% higher odds of being HIV positive. There was ethnic variation in patterns of HIV infection although the effect depended on the current place of residence. Copyright © 2012 Elsevier Ltd. All rights reserved.

Full Text Available Background: The global burden of conduct disorder is a major public health concern. Although there are different reports on the prevalence of conduct disorder in different Middle Eastern countries, to date, no research has reviewed them. Therefore, we aimed to conduct a systematic review and meta-analysis on the literature and present the prevalence of conduct disorder among children and adolescents in Middle Eastern countries.Methods: Those cross-sectional studies with any type of random or non-random sampling, which described the prevalence of conduct disorder prior to age of 18, for at least one gender in the general or school-based populations who resided in Middle Eastern countries were included in this review. The scientific databases of PubMed, Scopus, Google Scholar, Index Medicus for the Eastern Mediterranean Region (IMEMR, Islamic World Science Citation Center (ISC, and Grey Literature including conference proceedings, and hand searching of key journals were searched from 1995 to the end of 2014. Two reviewers assessed the quality of the included studies independently and extracted the relevant data.Discussion: This review provided a picture of different frequencies of conduct disorder in Middle Eastern countries and analyzed the sources of heterogeneity.Systematic Review Registration:PROSPERO CRD42014014996

Nutrition and mortality surveys are the main tools whereby evidence on the health status of populations affected by disasters and armed conflict is quantified and monitored over time. Several reviews have consistently revealed a lack of rigor in many surveys. We describe an algorithm for analyzing nutritional and mortality survey reports to identify a comprehensive range of errors that may result in sampling, response, or measurement biases and score quality. We apply the algorithm to surveys conducted in Darfur, Sudan. We developed an algorithm based on internationally agreed upon methods and best practices. Penalties are attributed for a list of errors, and an overall score is built from the summation of penalties accrued by the survey as a whole. To test the algorithm reproducibility, it was independently applied by three raters on 30 randomly selected survey reports. The algorithm was further applied to more than 100 surveys conducted in Darfur, Sudan. The Intra Class Correlation coefficient was 0.79 for mortality surveys and 0.78 for nutrition surveys. The overall median quality score and range of about 100 surveys conducted in Darfur were 0.60 (0.12-0.93) and 0.675 (0.23-0.86) for mortality and nutrition surveys, respectively. They varied between the organizations conducting the surveys, with no major trend over time. Our study suggests that it is possible to systematically assess quality of surveys and reveals considerable problems with the quality of nutritional and particularly mortality surveys conducted in the Darfur crisis.

Previous point prevalence surveys (PPSs) revealed the potential for improving antimicrobial usage (AU) in German acute care hospitals. Data from the 2016 German national PPS on healthcare-associated infections and AU were used to evaluate efforts in antimicrobial stewardship (AMS). A national PPS in Germany was organized by the German National Reference Centre for Surveillance of Nosocomial Infections in 2016 as part of the European PPS initiated by the ECDC. The data were collected in May and June 2016. Results were compared with data from the PPS 2011. A total of 218 hospitals with 64 412 observed patients participated in the PPS 2016. The prevalence of patients with AU was 25.9% (95% CI 25.6%-26.3%). No significant increase or decrease in AU prevalence was revealed in the group of all participating hospitals. Prolonged surgical prophylaxis was found to be common (56.1% of all surgical prophylaxes on the prevalence day), but significantly less prevalent than in 2011 (P < 0.01). The most frequently administered antimicrobial groups were penicillins plus β-lactamase inhibitors (BLIs) (23.2%), second-generation cephalosporins (12.9%) and fluoroquinolones (11.3%). Significantly more penicillins plus BLIs and fewer second-generation cephalosporins and fluoroquinolones were used in 2016. Overall, an increase in the consumption of broad-spectrum antimicrobials was noted. For 68.7% of all administered antimicrobials, the indication was documented in the patient notes. The current data reaffirm the points of improvement that previous data identified and reveal that recent efforts in AMS in German hospitals require further intensification.

Full Text Available The Prevalence and persistence of ADHD have not been described in young Australian adults and few studies have examined how conduct problems (CP are associated with ADHD for this age group. We estimate lifetime and adult prevalence and persistence rates for three categories of ADHD for 3795 Australian adults, and indicate how career, health and childhood risk factors differ for people with ADHD symptoms and ADHD symptoms plus CP.Trained interviewers collected participant experience of ADHD, CP, education, employment, childhood experience, relationship and health variables. Three diagnostic definitions of ADHD used were (i full DSM-IV criteria; (ii excluding the age 7 onset criterion (no age criterion; (iii participant experienced difficulties due to ADHD symptoms (problem symptoms.Prevalence rates in adulthood were 1.1%, 2.3% and 2.7% for each categorization respectively. Persistence of ADHD from childhood averaged across gender was 55.3% for full criteria, 50.3% with no age criterion and 40.2% for problem symptoms. ADHD symptoms were associated with parental conflict, poor health, being sexually assaulted during childhood, lower education, income loss and higher unemployment. The lifetime prevalence of conduct problems for adults with ADHD was 57.8% and 6.9% for adults without ADHD. The greatest disadvantage was experienced by participants with ADHD plus CP.The persistence of ADHD into adulthood was greatest for participants meeting full diagnostic criteria and inattention was associated with the greatest loss of income and disadvantage. The disadvantage associated with conduct problems differed in severity and was relevant for a high proportion of adults with ADHD. Women but not men with ADHD reported more childhood adversity, possibly indicating varied etiology and treatment needs. The impact and treatment needs of adults with ADHD and CP and the report of sexual assault during childhood by women and men with ADHD also deserve further study.

The prevalence of disability varies between countries ranging from less than 1% to up to 30% in some countries, thus, the estimated global disability prevalence is about 15%. However, it is unknown what the current estimate of disability and its types and severity are in Saudi Arabia. Thus, the objective of this study is to estimate national and regional prevalence rates of any disability, types of disability, and their severity among Saudi populations. Data on disability status were extracted from the national demographic survey conducted in 2016 as reported by the General Authority for Statistics, Saudi Arabia (N = 20,064,970). Prevalence rates per a population of 100,000 of any disability, type of disability, and its severity were calculated at the national level and in all 13 regions. Out of 20,064,970 Saudi citizens surveyed, 667,280 citizens reported disabilities, accounting for a prevalence rate of 3326 per a population of 100,000 (3.3%). Individuals aged 60 years and above (11,014) and males (3818) had a higher prevalence rate of disability compared with females (2813). The Tabuk region has the highest rate of reported disability, at 4.3%. The prevalence rates of extreme disabilities in mobility and sight were higher in Madinah (57,343) and Northern border (41,236) regions, respectively. In Saudi Arabia, more than half a million Saudi citizens (1 out of every 30 individuals) reported the presence of disability during the year 2016. A higher prevalence rate of disability was seen among those aged 60 years and above, and males. Targeted efforts are required at the national and regional levels to expand and improve rehabilitation and social services for all people with disabilities.

Contraception is one of the most important health interventions currently available and yet, many women and couples still do not have reliable access to modern contraceptives. The best indicator for monitoring family planning is the proportion of women using contraception among those who need it. This indicator is frequently called demand for family planning satisfied and we argue that it should be called family planning coverage (FPC). This indicator is complex to calculate and requires a considerable number of questions to be included in a household survey. We propose a model that can predict FPC from a much simpler indicator - contraceptive use prevalence - for situations where it cannot be derived directly. Using 197 Multiple Indicator Cluster Surveys and Demographic and Health Surveys from 82 countries, we explored least-squares regression models that could be used to predict FPC. Non-linearity was expected in this situation and we used a fractional polynomial approach to find the best fitting model. We also explored the effect of calendar time and of wealth on the models explored. Given the high correlation between the variables involved in FPC, we managed to derive a relatively simple model that depends only on contraceptive use prevalence but explains 95% of the variability of the outcome, with high precision for the estimated regression line. We also show that the relationship between the two variables has not changed with time. A concordance analysis showed agreement between observed and fitted results within a range of ±9 percentage points. We show that it is possible to obtain fairly good estimates of FPC using only contraceptive prevalence as a predictor, a strategy that is useful in situations where it is not possible to estimate FPC directly.

Full Text Available Abstract Background Educational attainment is an important determinant of diverse health outcomes. Truancy among adolescents jeopardizes chances of achieving their educational goals. Truant behaviors are also associated with various psychosocial problems. There is however limited data on the prevalence and factors associated with truancy among adolescents in Africa. Methods We used data from the Swaziland Global School-Based Health Survey (GSHS conducted in 2003 to estimate the prevalence of self-reported truancy within the last 30 days among adolescents. We also assessed the association between self-reported truancy and a selected list of independent variables using logistic regression analysis. Results A total of 7341 students participated in the study. In analysis of available data, 2526 (36.2% and 4470 (63.8% were males and females respectively. The overall prevalence of truancy within the last 30 days preceding the study was 21.6%. Prevalence of truancy was 27.4% (605 and 17.9% (723 in males and females respectively. In multivariate logistic regression analysis, being a male, having been bullied, lower school grades, and alcohol use were positively associated with truancy. Adolescents who perceived themselves as having parental support were less likely to have reported being truant. Conclusion Truancy among adolescents in Swaziland should be regarded as an important social problem as it is relatively prevalent. The design and implementation of intervention programs aimed to reduce truant behaviours should incorporate our knowledge of the factors identified as associated with bullying.

Full Text Available Abstract Background Nutrition and mortality surveys are the main tools whereby evidence on the health status of populations affected by disasters and armed conflict is quantified and monitored over time. Several reviews have consistently revealed a lack of rigor in many surveys. We describe an algorithm for analyzing nutritional and mortality survey reports to identify a comprehensive range of errors that may result in sampling, response, or measurement biases and score quality. We apply the algorithm to surveys conducted in Darfur, Sudan. Methods We developed an algorithm based on internationally agreed upon methods and best practices. Penalties are attributed for a list of errors, and an overall score is built from the summation of penalties accrued by the survey as a whole. To test the algorithm reproducibility, it was independently applied by three raters on 30 randomly selected survey reports. The algorithm was further applied to more than 100 surveys conducted in Darfur, Sudan. Results The Intra Class Correlation coefficient was 0.79 for mortality surveys and 0.78 for nutrition surveys. The overall median quality score and range of about 100 surveys conducted in Darfur were 0.60 (0.12-0.93 and 0.675 (0.23-0.86 for mortality and nutrition surveys, respectively. They varied between the organizations conducting the surveys, with no major trend over time. Conclusion Our study suggests that it is possible to systematically assess quality of surveys and reveals considerable problems with the quality of nutritional and particularly mortality surveys conducted in the Darfur crisis.

The aim of this study is to determine the prevalence and correlates of depressive symptoms in a school-based sample of 7-17-year-old children and adolescents in west-central China. A large cross-sectional sample survey of 10657 children and adolescents was conducted in Chongqing, a municipality in west-central China. Data were collected from the Children's Depression Inventory (CDI), Adolescent Self-Rating Life Events Checklist (ASLEC) and social-demographic variables which were evaluated with a structured scale. The total prevalence of depression risk was 23.9%. The risk factors for depressive symptoms included age older than 12 years, grade lower than 10, having unmarried parents, being taken care of by people other than two parents (single parent, grandparent(s), other relatives, or others), and living in a low-income family. The pressures of health and adaptation, interpersonal relationship, and study were also strong predictors of depressive symptoms. The prevalence of depressive symptoms among children and adolescents in Chongqing of China is relatively high compared with most figures reported in other cities. There is an urgent need to develop efficacious interventions aimed at the prevention and early recognition of childhood and adolescent depression. Copyright © 2016 Elsevier Ireland Ltd.

This study investigates sociodemographic and health-related correlates of use of a spiritual healer for medical help. A large national, multiracial-multiethnic data source permits a more comprehensive investigation than was possible in previous studies. It also enables a closer focus on socioeconomic disadvantage and health need as determinants of utilization. Respondents are from the National Survey of American Life: Coping with Stress in the 21st Century (NSAL), a nationally representative multi-stage area-probability survey of U.S. adult African Americans, Caribbean Blacks, and non-Hispanic Whites conducted from 2001 to 2003. The sample contains 6082 adults aged 18 and over. NSAL respondents were surveyed about lifetime use of alternative providers for medical care or advice. Response categories included two types of spiritual healers: faith healers and psychics. These outcomes were logistically regressed, separately, onto 10 sociodemographic or health-related indicators: race/ethnicity, age, gender, marital status, education, household income, region, medical care use, insurance coverage, and self-rated health. Lifetime utilization of a faith healer is more prevalent among respondents in good health and less prevalent among Caribbean Blacks and never married persons. Users of a psychic healer are more likely to be educated, residents of the Northeast or West, and previously married, and less likely to report excellent health. Use a spiritual healer is not due, on average, to poor education, marginal racial/ethnic or socioeconomic status, dire health straits, or lack of other healthcare options. To some extent, the opposite appears to be true. Use of a spiritual healer is not associated with fewer social and personal resources or limitations in health or healthcare.

Full Text Available Background & objectives: Studies conducted to assess the prevalence of cardiovascular (CV risk factors among different regions of the country show variation in risk factors in different age groups and urban and rural population. We undertook this study to determine the prevalence of cardiovascular risk factors among urban adults in a north Indian city. Methods: In a cross-sectional survey, 2227 subjects aged ≥ 20 yr were studied from April 2008 to June 2009 in Urban Chandigarh, a north Indian city. Demographic history, anthropometry and blood pressure were assessed. Fasting, and 2 h capillary plasma glucose after 75 g glucose load, HDL-C and triglycerides were estimated. Results: The most prevalent cardiovascular risk factors in the age group of 20-29 yr was sedentary lifestyle (63%, while from fourth decade and onwards, it was overweight/obesity (59-85%. The second most common prevalent cardiovascular risk factor in the age group of 20-29 yr was overweight/obesity, in 30-49 yr sedentary lifestyle, in 50-69 yr hypertension and in subjects ≥70 yr, it was hypertriglyceridaemia. The prevalence of overweight/obesity, hypertension, dysglycaemia and smoking was almost double in subjects in the fourth decade of life, as compared to those in the third decade of life. The prevalence of CV risk factors significantly increased with age irrespective of gender and prevalence of low HDL-C was significantly more common in women as compared to men. Interpretation & conclusions: Sedentary lifestyle, obesity and low HDL-C are the most prevalent CV risk factors in subjects in the third and fourth decade of life in this north Indian population and clustering of these cardiovascular risk factors increases with advancing age. Strategies need to be formulated to target this population to prevent the epidemic of cardiovascular disease.

The aim of this study was to determine the prevalence of substance use and addiction in Egypt and study its sociodemographic correlates. A total of 44,000 subjects were interviewed from 8 governorates by stratified sampling. A questionnaire derived from the Addiction Severity Index (ASI) was individually administered. The lifetime prevalence of any substance use varies between 7.25% and 14.5%. One-month prevalence varies between 5.4% and 11.5% when adjusted to different population parameters. A total of 4832 subjects were identified as using illicit substances at least once in their life (9.6%), including 1329 experimental and social use (3.3%), 1860 regular use (4.64%), and 629 substance dependence (1.6%). The prevalence of substance use in males is 13.2% and 1.1% in females. Prevalence increases significantly in males of Bedouin origin, in seaside governorates, with lesser levels of education, and in certain occupations. The 15-19 age group showed the highest onset of substance use. Cannabis is the drug mostly misused in Egypt; alcohol is a distant second. The prevalence of substance use is lower than Western countries and higher compared with a 1996 survey. The true population prevalence is probably higher due to underreporting. The demographic pattern reflects availability and accessibility to drugs.

Reliability of Nationwide Prevalence Estimates of Dementia: A Critical Appraisal Based on Brazilian Surveys.

Directory of Open Access Journals (Sweden)

Flávio Chaimowicz

Full Text Available The nationwide dementia prevalence is usually calculated by applying the results of local surveys to countries' populations. To evaluate the reliability of such estimations in developing countries, we chose Brazil as an example. We carried out a systematic review of dementia surveys, ascertained their risk of bias, and present the best estimate of occurrence of dementia in Brazil.We carried out an electronic search of PubMed, Latin-American databases, and a Brazilian thesis database for surveys focusing on dementia prevalence in Brazil. The systematic review was registered at PROSPERO (CRD42014008815. Among the 35 studies found, 15 analyzed population-based random samples. However, most of them utilized inadequate criteria for diagnostics. Six studies without these limitations were further analyzed to assess the risk of selection, attrition, outcome and population bias as well as several statistical issues. All the studies presented moderate or high risk of bias in at least two domains due to the following features: high non-response, inaccurate cut-offs, and doubtful accuracy of the examiners. Two studies had limited external validity due to high rates of illiteracy or low income. The three studies with adequate generalizability and the lowest risk of bias presented a prevalence of dementia between 7.1% and 8.3% among subjects aged 65 years and older. However, after adjustment for accuracy of screening, the best available evidence points towards a figure between 15.2% and 16.3%.The risk of bias may strongly limit the generalizability of dementia prevalence estimates in developing countries. Extrapolations that have already been made for Brazil and Latin America were based on a prevalence that should have been adjusted for screening accuracy or not used at all due to severe bias. Similar evaluations regarding other developing countries are needed in order to verify the scope of these limitations.

To describe the prevalence of mental disorders (period prevalence across aggregated disorders, 12 month and lifetime prevalence) among Māori in Te Rau Hinengaro: The New Zealand Mental Health Survey. Te Rau Hinengaro: The New Zealand Mental Health Survey, undertaken between 2003 and 2004, was a nationally representative face-to-face household survey of 12,992 New Zealand adults aged 16 years and over, including 2,595 Māori. Ethnicity was measured using the 2001 New Zealand census ethnicity question. A fully structured diagnostic interview, the World Health Organization World Mental Health Survey Initiative version of the Composite International Diagnostic Interview (CIDI 3.0), was used to measure disorder. The overall response rate was 73.3%. This paper presents selected findings for the level and pattern of mental disorder prevalence among Māori. Māori lifetime prevalence of any disorder was 50.7%, 12 month prevalence 29.5% and 1 month prevalence 18.3%. The most common 12 month disorders were anxiety (19.4%), mood (11.4%) and substance (8.6%) disorders and the most common lifetime disorders were anxiety (31.3%), substance (26.5%) and mood (24.3%) disorders. Levels of lifetime comorbidity were high with 12 month prevalence showing 16.4% of Māori with one disorder, 7.6% with two disorders and 5.5% with three or more disorders. Twelve-month disorders were more common in Māori females than in males (33.6%vs 24.8%) and in younger age groups: 16-24 years, 33.2%; 25-44 years, 32.9%; 45-64 years, 23.7%; and 65 years and over, 7.9%. Disorder prevalence was greatest among Māori with the lowest equivalized household income and least education. However, differences by urbanicity and region were not significant. Of Māori with any 12 month disorder, 29.6% had serious, 42.6% had moderate and 27.8% had mild disorders. Mental disorders overall and specific disorder groups (anxiety, mood and substance) are common among Māori and measures of severity indicate that disorders

Full Text Available Abstract Background Child maltreatment can cause significant physical and psychological problems. The present study aimed to investigate the prevalence and determinants of child maltreatment in Guangzhou, China, where such issues are often considered a taboo subject. Methods A school-based survey was conducted in southern China in 2005. 24 high schools were selected using stratified random sampling strategy based on their districts and bandings. The self-administered validated Chinese version of parent-child Conflict Tactics Scale (CTSPC was used as the main assessment tool to measure the abusive experiences encountered by students in the previous six months. Results The response rate of this survey was 99.7%. Among the 6592 responding students, the mean age was 14.68. Prevalence of parental psychological aggression, corporal punishment, severe and very serve physical maltreatment in the past 6 months were 78.3%, 23.2%, 15.1% and 2.8% respectively. The prevalence of sexual abuse is 0.6%. The most commonly cited reasons for maltreatment included 'disobedience to parents', 'poor academic performance', and 'quarrelling between parents'. Age, parental education, places of origins and types of housing were found to be associated with physical maltreatments whereas gender and fathers' education level were associated with sexual abuse. Conclusion Though largely unspoken, child maltreatment is a common problem in China. Identification of significant determinants in this study can provide valuable information for teachers and health professionals so as to pay special attention to those at-risk children.

Full Text Available BACKGROUND: Despite historical evidence of blinding trachoma, there have been no widespread contemporary surveys of trachoma prevalence in the northern states of Sudan. We aimed to conduct district-level surveys in this vast region in order to map the extent of the problem and estimate the need for trachoma control interventions to eliminate blinding trachoma. METHODS AND FINDINGS: Separate, population based cross-sectional surveys were conducted in 88 localities (districts in 12 northern states of Sudan between 2006 and 2010. Two-stage cluster random sampling with probability proportional to size was used to select the sample. Trachoma grading was done using the WHO simplified grading system. Key prevalence indicators were trachomatous inflammation-follicular (TF in children aged 1-9 years and trachomatous trichiasis (TT in adults aged 15 years and above. The sample comprised 1,260 clusters from which 25,624 households were surveyed. A total of 106,697 participants (81.6% response rate were examined for trachoma signs. TF prevalence was above 10% in three districts and between 5% and 9% in 11 districts. TT prevalence among adults was above 1% in 20 districts (which included the three districts with TF prevalence >10%. The overall number of people with TT in the population was estimated to be 31,072 (lower and upper bounds = 26,125-36,955. CONCLUSION: Trachoma mapping is complete in the northern states of Sudan except for the Darfur States. The survey findings will facilitate programme planning and inform deployment of resources for elimination of trachoma from the northern states of Sudan by 2015, in accordance with the Sudan Federal Ministry of Health (FMOH objectives.

Control of rodent adventitial infections in biomedical research facilities is of extreme importance in assuring both animal welfare and high-quality research results. Sixty-three U.S. institutions participated in a survey reporting the methods used to detect and control these infections and the prevalence of outbreaks from 1 January 2014 through 31 December 2015. These results were then compared with the results of 2 similar surveys published in 1998 and 2008. The results of the current survey demonstrated that the rate of viral outbreaks in mouse colonies was decreasing, particularly in barrier facilities, whereas the prevalence of parasitic outbreaks has remained constant. These results will help our profession focus its efforts in the control of adventitial rodent disease outbreaks to the areas of the greatest needs.

Associations between psychosocial job characteristics and past myocardial infarction (MI) prevalence for employed males were tested with the Health Examination Survey (HES) 1960-61, N = 2,409, and the Health and Nutrition Examination Survey (HANES) 1971-75, N = 2,424. A new estimation method is used which imputes to census occupation codes, job characteristic information from national surveys of job characteristics (US Department of Labor, Quality of Employment Surveys). Controlling for age, we find that employed males with jobs which are simultaneously low in decision latitude and high in psychological work load (a multiplicative product term isolating 20 per cent of the population) have a higher prevalence of myocardial infarction in both data bases. In a logistic regression analysis, using job measures adjusted for demographic factors and controlling for age, race, education, systolic blood pressure, serum cholesterol, smoking (HANES only), and physical exertion, we find a low decision latitude/high psychological demand multiplicative product term associated with MI in both data bases. Additional multiple logistic regressions show that low decision latitude is associated with increased prevalence of MI in both the HES and the HANES. Psychological workload and physical exertion are significant only in the HANES.

Full Text Available Abstract Background Psychiatric surveys conducted in prison populations find high prevalence rates, but diagnoses may be difficult in this particular context. None of these surveys have been conducted in France. Methods 800 incarcerated male were sampled at random. Each prisoner was interviewed by a group of 2 clinicians, at least one of them being a senior psychiatrist. One of the clinicians used a structured clinical interview which generated DSM IV diagnosis (MINI plus; the second completed the procedure with an open clinical interview. Results Prevalence rates for a diagnosis given independently by both clinicians and for a consensual diagnosis were respectively: 3.8% (6.2% for schizophrenia, 17.9% (24% for major depressive disorder, 12.0% (17.7% for generalized anxiety and 10.8% (14.6% for drug dependence. Conclusion Psychiatric diagnosis can be difficult to interpret in prison, especially using traditional standardized interviews. The approach proposed here, with good reliability and closer to a day-to-day clinical practice, yields high prevalence rates.

Full Text Available Hypertension has become the leading cause of death worldwide; data on hypertension among Nanchang adults are sparse. The aim of this study was to investigate the prevalence and gender-specific influencing factors of hypertension in adults in Nanchang, China. A cross-sectional survey was conducted with a representative sample of 2722 Chinese residents aged 18 years and above between May and September 2016, with a response rate of 92.4% (2516/2722. A stratified cluster sampling method was adopted in this study. Data on prevalence and influencing factors were obtained from a standard questionnaire and physical measurements. Univariate and multivariate logistic regressions were performed to analyze the influencing factors. The age-standardized prevalence was 19.8% (18.2–21.3 (male: 19.5% (18.0–21.1; female, 20.01% (18.5–21.6. Factors positively associated with hypertension prevalence were past smoking, diabetes mellitus (DM, and overweight and obesity in both genders. Abdominal obesity and family history of cardiovascular diseases (CVD were risk factors only in males; sleeping time and consumption of fresh vegetables and fruits were related to the prevalence of hypertension only in females. These findings will form the baseline information for the development of more effective approaches to enhance current prevention and control management of hypertension.

Duc Anh Ha

Full Text Available Cardiovascular disease (CVD is one of the leading causes of morbidity and mortality in Vietnam and hypertension (HTN is an important and prevalent risk factor for CVD in the adult Vietnamese population. Despite an increasing prevalence of HTN in this country, information about the awareness, treatment, and control of HTN is limited. The objectives of this study were to describe the prevalence, awareness, treatment, and control of HTN, and factors associated with these endpoints, in residents of a mountainous province in Vietnam.Data from 2,368 adults (age≥25 years participating in a population-based survey conducted in 2011 in Thai Nguyen province were analyzed. All eligible participants completed a structured questionnaire and were examined by community health workers using a standardized protocol.The overall prevalence of HTN in this population was 23%. Older age, male sex, and being overweight were associated with a higher odds of having HTN, while higher educational level was associated with a lower odds of having HTN. Among those with HTN, only 34% were aware of their condition, 43% of those who were aware they had HTN received treatment and, of these, 39% had their HTN controlled.Nearly one in four adults in Thai Nguyen is hypertensive, but far fewer are aware of this condition and even fewer have their blood pressure adequately controlled. Public health strategies increasing awareness of HTN in the community, as well as improvements in the treatment and control of HTN, remain needed to reduce the prevalence of HTN and related morbidity and mortality.

2018-02-06

Based on a survey of 9512 ninth-grade students conducted in Lower Saxony in 2013, this paper examines the prevalence of cyberbullying perpetration and the correlates of this behavior. Binary logistic multilevel regression was used in order to analyze correlates of sexual and psychological cyberbully perpetration. In the preceding semester, 2.4% of the adolescents were perpetrators of psychological cyberbullying and 0.4% bullied someone online sexually. Low levels of empathy, frequent consumption of violent media, and being victims of aggressive online behaviors are correlated with the risk that a child will become a bully. Female adolescents are less likely than boys to engage in sexual cyberbullying perpetration, but they are more likely to engage in psychological cyberbullying perpetration. Only a small share of adolescents engage in sexual and psychological cyberbullying perpetration. Both behaviors differ in their correlates, however being a victim of aggressive online behaviors increase the risk for perpetration of both behaviors, respectively.

Full Text Available BackgroundDiabetic nephropathy is a leading cause of end stage renal disease and is associated with an increased risk of cardiovascular mortality. It manifests as albuminuria or impaired glomerular filtration rate (GFR, and the prevalence of diabetic nephropathy varies with ethnicity. The prevalence of diabetic nephropathy and its determinants in Korean adults have not previously been studied at the national level. This cross-sectional study was undertaken to ascertain the prevalence and determinants of albuminuria and chronic kidney disease (CKD in Korean patients with diabetes.MethodsThe Korea National Health and Nutrition Examination Survey (KNHANES V, conducted in 2011, was used to define albuminuria (n=4,652, and the dataset of KNHANES IV-V (2008-2011 was used to define CKD (n=21,521. Selected samples were weighted to represent the entire civilian population in Korea. Albuminuria was defined as a spot urine albumin/creatinine ratio >30 mg/g. CKD was defined as a GFR <60 mL/min/1.73 m2.ResultsAmong subjects with diabetes, 26.7% had albuminuria, and 8.6% had CKD. Diabetes was associated with an approximate 2.5-fold increased risk of albuminuria, with virtually no difference between new-onset and previously diagnosed diabetes. Only systolic blood pressure was significantly associated with albuminuria, and old age, high serum triglyceride levels, and previous cardiovascular disease (CVD were related with CKD in subjects with diabetes.ConclusionKorean subjects with diabetes had a higher prevalence of albuminuria and CKD than those without diabetes. Blood pressure was associated with albuminuria, and age, triglyceride level, and previous CVD were independent determinants of CKD in subjects with diabetes.

The 2015 National Mental Health Survey aimed to expand our knowledge about the real mental state of children in Colombia, taking into account the fact that most mental disorders in adults begin during childhood or adolescence. It is essential to have an improved knowledge of the magnitude of this issue and to design timely interventions that reduce long term complications. The aim of the study was to determine the prevalence of the disorders in the last 12 months and 30 days according to the DSM-IV, as well as to collect data about social and demographic variables. The structured Diagnostic Interview Schedule for Children (DISC-P), which provides DSM-IV diagnoses, was applied to carers of non-institutionalised children between 7 and 11 years old. The disorders evaluated included: major depressive disorder, dysthymia, generalised anxiety disorder, separation anxiety disorder, attention deficit hyperactivity disorder in its three kinds (mixed, inattentive, and hyperactive), oppositional defiant disorder, and conduct disorder. The instrumentation was computer-assisted. Prevalences of the disorders are present both in the last 30 days and in the last 12 months. In general, there is a prevalence of any of the disorders of 3% (95% CI, 2.2-4.0) in the last 30 days, and 4.7% (95% CI, 3.6-6.2) in the last 12 months. When evaluated individually, attention deficit hyperactivity disorder is the most frequent disorder, with a prevalence of 2.3% and 3.0% in the last 30 days and the last 12 months, respectively. In addition, the disorders that are known to frequently begin during childhood are the most common disorders in the age group studied, with a prevalence of 2.5% in the last 30 days and 3.2% in the last year. The 2015 National Mental Health Survey provides precise information about the real mental situation in children between the ages of 7 and 11 years in Colombia, compared with past epidemiological studies in the country, which were restricted to specific populations.

Several studies in The Netherlands revealed ethnic disparities in hypertension prevalence, but none have focused on the Moluccan-Dutch, a migrant group from Indonesia that settled in The Netherlands in 1951. The Moluccan-Dutch are considered to be fairly well integrated in Dutch society. The aim of this study was to compare hypertension prevalence among the Moluccan-Dutch to the native Dutch and to explore the contribution of known risk factors. A health interview survey was conducted from August 2012 till March 2013 among nineteen Moluccan neighborhoods, resulting in the inclusion of 708 participants. The primary outcome variable was self-reported prevalence of hypertension. Explanatory variables were BMI, exercise, smoking, alcohol intake and mental health status. Data on the control group was extracted from the Dutch National Health Survey 2011, using a similar questionnaire. Differences in risk factor exposure were explored using Chi-square tests and the contribution of risk factors, separately and combined, was explored using multivariate logistic regression analysis. Moluccan-Dutch showed higher odds for reporting hypertension when compared to native Dutch, after adjusting for age and level of education (OR = 1.38; 95% CI = 1.13-1.69) and additional risk factors (OR = 1.49; 95% CI = 1.19-1.88). A higher prevalence of hypertension was found in both Moluccan-Dutch men (26.4% vs. 16.7%; p Dutch men showed higher prevalence of hypertension. The Moluccan-Dutch may be at increased risk for reporting hypertension. These results suggest that long-term stay over several generations does not necessarily result in similar levels of hypertension prevalence as the host population.

This cross-sectional study sought to determine the prevalence of attention-deficit/hyperactivity disorder (ADHD) and conduct disorder among adults admitted to 2 chemical dependency treatment centers. It was hypothesized that ADHD alone or in combination with conduct disorder would be overrepresented in a population of patients with psychoactive substance use disorders. Two hundred one participants were selected randomly from 2 chemical dependency treatment centers. Standardized clinical interviews were conducted using the Structured Clinical Interview for DSM-IV, the Addiction Severity Index, and DSM-IV criteria for ADHD. Reliabilities for the diagnostic categories were established using the Cohen kappa, and the subgroups of individuals with and without ADHD and conduct disorder were compared. Forty-eight (24%) of the participants were found to meet DSM-IV criteria for ADHD. The prevalence of ADHD was 28% in men (30/106) and 19% in women (18/95; NS). Seventy-nine participants (39%) met criteria for conduct disorder, and 34 of these individuals also had ADHD. Overall, individuals with ADHD (compared with those without ADHD) were more likely to have had more motor vehicle accidents. Women with ADHD (in comparison with women without ADHD) had a higher number of treatments for alcohol abuse. Individuals with conduct disorder (in comparison with those without conduct disorder) were younger, had a greater number of jobs as adults, and were more likely to repeat a grade in school, have a learning disability, be suspended or expelled from school, have an earlier age at onset of alcohol dependence, and have had a greater number of treatments for drug abuse. They were more likely to have a lifetime history of abuse of and/or dependence on cocaine, stimulants, hallucinogens, and/or cannabis. A significant overrepresentation of ADHD exists among inpatients with psychoactive substance use disorders. Over two thirds of those with ADHD in this sample also met criteria for conduct

Cross-sectional blindness prevalence surveys are essential to plan and monitor eye care services. Incomplete or inaccurate reporting can prevent effective translation of research findings. The Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) statement is a 32 item checklist developed to improve reporting of observational studies. The aim of this study was to assess the completeness of reporting in blindness prevalence surveys in low and middle income countries (LMICs) using STROBE. MEDLINE, EMBASE and Web of Science databases were searched on April 8 2016 to identify cross-sectional blindness prevalence surveys undertaken in LMICs and published after STROBE was published in December 2007. The STROBE tool was applied to all included studies, and each STROBE item was categorized as 'yes' (met criteria), 'no' (did not meet criteria) or 'not applicable'. The 'Completeness of reporting (COR) score' for each manuscript was calculated: COR score = yes / [yes + no]. In journals with included studies the instructions to authors and reviewers were checked for reference to STROBE. The 89 included studies were undertaken in 32 countries and published in 37 journals. The mean COR score was 60.9% (95% confidence interval [CI] 58.1-63.7%; range 30.8-88.9%). The mean COR score did not differ between surveys published in journals with author instructions referring to STROBE (10/37 journals; 61.1%, 95%CI 56.4-65.8%) or in journals where STROBE was not mentioned (60.9%, 95%CI 57.4-64.3%; p = 0.93). While reporting in blindness prevalence surveys is strong in some areas, others need improvement. We recommend that more journals adopt the STROBE checklist and ensure it is used by authors and reviewers.

Full Text Available Prior studies show that perceived smoking prevalence is a significant predictor of smoking initiation. In this study, we examine racial/ethnic differences in perceived smoking prevalence and racial/ethnic differences in exposure to contextual factors associated with perceived smoking prevalence. We used cross-sectional time series data from the Legacy Media Tracking Surveys (LMTS, a national sample of 35,000 12- to 17-year-olds in the United States. Perceived smoking prevalence was the primary outcome variable, measured using an LMTS question: “Out of every 10 people your age, how many do you think smoke?” Multivariable models were estimated to assess the association between perceived smoking prevalence; race/ethnicity; and exposure to social contextual factors. Findings indicate that African American, Hispanic, and American Indian youth exhibit the highest rates of perceived smoking prevalence, while white and Asian youth exhibit the lowest. Minority youth are also disproportionately exposed to social contextual factors that are correlated with high perceived smoking prevalence. These findings suggest that disproportionate exposure to social contextual factors may partially explain why minority youth exhibit such high levels of perceived smoking prevalence.

Objectives To determine optimum measurements for abdominal obesity and to assess the prevalence and determinants of metabolic syndrome in Qatar. Design National health survey. Setting Qatar National STEPwise Survey conducted by the Supreme Council of Health during 2012. Participants 2496 Qatari citizens aged 18–64 representative of the general population. Primary and secondary outcome measures Measure of obesity (body mass index, waist circumference or waist-to-height ratio) that best identified the presence of at least 2 other factors of metabolic syndrome; cut-off values of waist circumference; frequency of metabolic syndrome. Results Waist circumference ≥102 for men and ≥94 cm for women was the best predictor of the presence of other determinants of metabolic syndrome (raised blood pressure, fasting blood glucose, triglycerides and reduced high-density lipoprotein cholesterol). Using these values, we identified 28% of Qataris with metabolic syndrome, which is considerably lower than the estimate of 37% calculated using the International Diabetes Federation (IDF) criteria. Restricting the analysis to participants without known elevated blood pressure, elevated blood sugar or diabetes 16.5% would be classified as having metabolic syndrome. In a multivariable logistic regression analysis, the prevalence of metabolic syndrome increased steadily with age (OR=3.40 (95% CI 2.02 to 5.74), OR=5.66 (3.65 to 8.78), OR=10.2 (5.98 to 17.6) and OR=18.2 (7.01 to 47.5) for those in the age group ‘30–39’, ‘40–49’, ‘50–59’, ‘60–64’ vs ‘18–29’; pQatar. Approximately 28% of adult Qatari citizens satisfy the criteria for metabolic syndrome, which increased significantly with age. Education and physical activity were inversely associated with this syndrome. PMID:27601485

Paulo A. Lotufo

Full Text Available Abstract Background: Data on the prevalence of dyslipidemia in Brazil are scarce, with surveys available only for some towns. Objective: To evaluate the prevalence of the self-reported medical diagnosis of high cholesterol in the Brazilian adult population by use of the 2013 National Health Survey data. Methods: Descriptive study assessing the 2013 National Health Survey data, a household-based epidemiological survey with a nationally representative sample and self-reported information. The sample consisted of 60,202 individuals who reported a medical diagnosis of dyslipidemia. The point prevalence and 95% confidence interval (95%CI for the medical diagnosis of high cholesterol/triglyceride by gender, age, race/ethnicity, geographic region and educational level were calculated. Adjusted odds ratio was calculated. Results: Of the 60,202 participants, 14.3% (95%CI=13.7-14.8 never had their cholesterol or triglyceride levels tested, but a higher frequency of women, white individuals, elderly and those with higher educational level had their cholesterol levels tested within the last year. The prevalence of the medical diagnosis of high cholesterol was 12.5% (9.7% in men and 15.1% in women, and women had 60% higher probability of a diagnosis of high cholesterol than men. The frequency of the medical diagnosis of high cholesterol increased up to the age of 59 years, being higher in white individuals or those of Asian heritage, in those with higher educational level and in residents of the Southern and Southeastern regions. Conclusion: The importance of dyslipidemia awareness in the present Brazilian epidemiological context must be emphasized to guide actions to control and prevent coronary heart disease, the leading cause of death in Brazil and worldwide.

Rapid integrated clinical survey to determine prevalence and co-distribution patterns of lymphatic filariasis and onchocerciasis in a Loa loa co-endemic area: The Angolan experience

2017-08-01

Full Text Available The Republic of Angola is a priority country for onchocerciasis and lymphatic filariasis (LF elimination, however, the co-distribution of the filarial parasite Loa loa (loiasis is a significant impediment, due to the risk of severe adverse events (SAEs associated with ivermectin used in mass drug administration (MDA campaigns. Angola has a high risk loiasis zone identified in Bengo Province where alternative interventions may need to be implemented; however, the presence and geographical overlap of the three filarial infections/diseases are not well defined. Therefore, this study conducted a rapid integrated filarial mapping survey based on readily identifiable clinical conditions of each disease in this risk zone to help determine prevalence and co-distribution patterns in a timely manner with limited resources. In total, 2007 individuals from 29 communities in five provincial municipalities were surveyed. Community prevalence estimates were determined by the rapid assessment procedure for loiasis (RAPLOA and rapid epidemiological mapping of onchocerciasis (REMO together with two questions on LF clinical manifestations (presence of lymphoedema, hydrocoele. Overall low levels of endemicity, with different overlapping distributions were found. Loiasis was found in 18 communities with a prevalence of 2.0% (31/1571, which contrasted to previous results defining the area as a high risk zone. Onchocerciasis prevalence was 5.3% (49/922 in eight communities, and LF prevalence was 0.4% for lymphoedema (8/2007 and 2.6% for hydrocoeles (20/761 males in seven and 12 communities respectively. The clinical mapping survey method helped to highlight that all three filarial infections are present in this zone of Bengo Province. However, the significant difference in loiasis prevalence found between the past and this current survey suggests that further studies including serological and parasitological confirmation are required. This will help determine levels

The development of epidemiological instruments has enabled the assessment of mental disorders in youth in countries that plan policy according to evidence-based principles. The Israel Survey of Mental Health among Adolescents (ISMEHA) was conducted in 2004-2005 in a representative sample of 957 adolescents aged 14-17 and their mothers. The aims of this study were to estimate prevalence rates of internalizing and externalizing mental disorders and their socio-demographic and health correlates. Disorders were ascertained with the Development and Well-Being Assessment inventory and verified by child psychiatrists. The prevalence rates were 11.7%, 8.1% and 4.8% for any disorder, internalizing disorders and externalizing disorders, respectively. Distinct risk factors were associated with the different types of disorders: internalizing disorders were associated with female gender, chronic medical conditions and being cared for by a welfare agency. Risk factors for externalizing disorders were male gender, having divorced or single parents, being an only child or having only one sibling. Learning disability was associated with both types of disorders. The risk and protective factors related to internalizing and externalizing disorders are interpreted within the framework of family composition in this multicultural society.

Ecological study of socio-economic indicators and prevalence of asthma in schoolchildren in urban Brazil

Genser Bernd

2007-08-01

Full Text Available Abstract Background There is evidence of higher prevalence of asthma in populations of lower socio-economic status in affluent societies, and the prevalence of asthma is also very high in some Latin American countries, where societies are characterized by a marked inequality in wealth. This study aimed to examine the relationship between estimates of asthma prevalence based on surveys conducted in children in Brazilian cities and health and socioeconomic indicators measured at the population level in the same cities. Methods We searched the literature in the medical databases and in the annals of scientific meeting, retrieving population-based surveys of asthma that were conducted in Brazil using the methodology defined by the International Study of Asthma and Allergies in Childhood. We performed separate analyses for the age groups 6–7 years and 13–14 years. We examined the association between asthma prevalence rates and eleven health and socio-economic indicators by visual inspection and using linear regression models weighed by the inverse of the variance of each survey. Results Six health and socioeconomic variables showed a clear pattern of association with asthma. The prevalence of asthma increased with poorer sanitation and with higher infant mortality at birth and at survey year, GINI index and external mortality. In contrast, asthma prevalence decreased with higher illiteracy rates. Conclusion The prevalence of asthma in urban areas of Brazil, a middle income country, appears to be higher in cities with more marked poverty or inequality.

To describe the prevalence of metabolic syndrome among older adults in Ecuador. A secondary objective was to examine the relationship between metabolic syndrome and its components and insulin resistance among non-diabetic participants. The National Survey of Health, Wellbeing, and Aging survey was used to examine the prevalence of metabolic syndrome according to demographic, behavioral, and health characteristics of the participants. Logistic regression models adjusted for covariates were used to examine the independent association of metabolic syndrome and its components and insulin resistance in non-diabetic older adults. Of 2298 participants with a mean age of 71.6 (SD 8.1) years, the prevalence of metabolic syndrome was 66.0% (95% CI, 62.6%, 69.3%) in women and 47.1% (95% CI, 43.2%, 50.9) in men. However, even higher prevalence rates were seen among literate individuals, residents from urban areas of the coastal and Andes Mountains region, obese subjects, those diagnosed with diabetes, and participants with≥2 comorbidities. Overall, abdominal obesity followed by elevated blood pressure were the metabolic syndrome components more prevalent and associated with insulin resistance among older Ecuadorians. Moreover, after adjustment for covariates, older adults defined as having metabolic syndrome had a 3-fold higher odds of having insulin resistance as compared with those without. The prevalence of metabolic syndrome is high among older adults in Ecuador. The present findings may assist public health authorities to implement programs of lifestyle and behavioral modification targeting older adults at increased risk for this cardio metabolic disorder.

Full Text Available BACKGROUND: Accurate information on the prevalence and causes of musculoskeletal impairment (MSI is lacking in low income countries. We present a new survey methodology that is based on sound epidemiological principles and is linked to the World Health Organisation's International Classification of Functioning. METHODS: Clusters were selected with probability proportionate to size. Households were selected within clusters through compact segment sampling. 105 clusters of 80 people (all ages were included. All participants were screened for MSI by a physiotherapist and medical assistant. Possible cases plus a random sample of 10% of non-MSI cases were examined further to ascertain diagnosis, aetiology, quality of life, and treatment needs. FINDINGS: 6757 of 8368 enumerated individuals (80.8% were screened. There were 352 cases, giving an overall prevalence for MSI of 5.2%. (95% CI 4.5-5.9 The prevalence of MSI increased with age and was similar in men and women. Extrapolating these estimates, there are approximately 488,000 MSI diagnoses in Rwanda. Only 8.2% of MSI cases were severe, while the majority were moderate (43.7% or mild (46.3%. Diagnostic categories comprised 11.5% congenital, 31.3% trauma, 3.8% infection, 9.0% neurological, and 44.4% non-traumatic non infective acquired. The most common individual diagnoses were joint disease (13.3%, angular limb deformity (9.7% and fracture mal- and non-union (7.2%. 96% of all cases required further treatment. INTERPRETATION: This survey demonstrates a large burden of MSI in Rwanda, which is mostly untreated. The survey methodology will be useful in other low income countries, to assist with planning services and monitoring trends.

Spiegel Paul B

2007-06-01

Full Text Available Abstract Background Malnutrition prevalence and mortality rates are increasingly used as essential indicators to assess the severity of a crisis, to follow trends, and to guide decision-making, including allocation of funds. Although consensus has slowly developed on the methodology to accurately measure these indicators, errors in the application of the survey methodology and analysis have persisted. The aim of this study was to identify common methodological weaknesses in nutrition and mortality surveys and to provide practical recommendations for improvement. Methods Nutrition (N = 368 and crude mortality rate (CMR; N = 158 surveys conducted by 33 non-governmental organisations and United Nations agencies in 17 countries from October 1993 to April 2004 were analysed for sampling validity, precision, quality of measurement and calculation according to several criteria. Results One hundred and thirty (35.3% nutrition surveys and 5 (3.2% CMR surveys met the criteria for quality. Quality of surveys varied significantly depending on the agency. The proportion of nutrition surveys that met criteria for quality rose significantly from 1993 to 2004; there was no improvement for mortality surveys during this period. Conclusion Significant errors and imprecision in the methodology and reporting of nutrition and mortality surveys were identified. While there was an improvement in the quality of nutrition surveys over the years, the quality of mortality surveys remained poor. Recent initiatives aimed at standardising nutrition and mortality survey quality should be strengthened. There are still a number of methodological issues in nutrition and mortality surveys in humanitarian emergencies that need further study.

Excessive weight gain has been reported to occur in captive cynomolgus macaques with little to no change in diet. Overweight body condition can result in development of hyperglycemia and type 2 diabetes and should be avoided. The purpose of this survey was to assess the prevalence of overweight cynomolgus macaques in North American research facilities, including breeding colonies and short-term and long-term facilities, and to describe current methods used to assess body condition. The survey consisted of 51 questions covering animal population demographics, body weight and body condition scoring, feeding, and behavior. Voluntary participants included veterinarians and animal care managers. Respondents from 13 facilities completed the survey, and information was collected on 17,500 cynomolgus macaques. The majority of surveyed facilities housed juvenile and young adult macaques. The reported prevalence of overweight (greater than 10% of ideal body weight) animals ranged between 0% and 20% and reportedly was more frequent in animals younger than 10 y. Most facilities had weight reduction strategies in place. Despite these programs, a significant proportion of animals were reported as being overweight. The results of this survey demonstrate that most North American facilities housing cynomolgus macaques recognize the importance of tracking body condition regularly. However, implementing effective weight reduction programs may be difficult in captive housing environments. Because of the potential for adverse health effects, facilities should have a means of regularly tracking body weight as well as an action plan for managing overweight animals.

To measure the prevalence of domestic violence (DV) experienced by women seeking termination of pregnancy (TOP) in a UK abortion clinic. A cross-sectional anonymous questionnaire survey of all women aged over 16 years accessing a TOP clinic in inner London between 20 May 2012 and 2 July 2012. The main outcome measures were: distribution of questionnaires, response rate, lifetime prevalence of abuse, past-year prevalence of physical and sexual abuse, prevalence of physical abuse during current pregnancy, relationship of lifetime abuse to number of terminations, and receptivity to DV services. Questionnaires were distributed to 46% (383/828) of women accessing the clinic. Response rate was 50% (190/383). Lifetime prevalence of abuse was 16%. Past-year prevalence of physical abuse was 11% and sexual abuse was 4%. Prevalence of physical abuse during the current pregnancy was 4%. Prevalence of lifetime abuse was lower in women having a first termination (12%) versus one (20%) or two or more previous terminations (24%), although this was not statistically significant (p=0.192). The majority (75%) of participants expressing an opinion on the possibility of having a support service for DV in the abortion clinic setting were positive, unrelated to their personal experience, but some concerns were raised about implementation. In order to provide effective support for women, services require a needs assessment of their local population. Asking women presenting for abortion about DV, even anonymously, is challenging but feasible. Future work should be directed to women's unmet safety needs.

Full Text Available OBJECTIVE: To estimate the prevalence of risk factors for HIV infection among Mexican migrants and immigrants (MMIs in different geographic contexts, including the sending communities in Mexico, the receiving communities in the United States (US, and the Mexican North border region. MATERIAL AND METHODS: We conducted a probability survey among MMIs traveling through key border crossing sites in the Tijuana (Baja California, Mexico-San Diego (California, US border region (N=1 429. RESULTS: The survey revealed substantial rates of reported sexually transmitted infections, needle-sharing and sexual risk practices in all migration contexts. CONCLUSIONS: The estimated levels of HIV risk call for further binational research and preventive interventions in all key geographic contexts of the migration experience to identify and tackle the different personal, environmental, and structural determinants of HIV risk in each of these contexts.

To describe the prevalence of lipid abnormalities found in the Mexican National Health and Nutrition Survey 2006 (ENSANut 2006). Information was obtained from 4 040 subjects aged 20 to 69 years, studied after a 9- to 12-hour fast. Median lipid concentrations were: cholesterol 198.5 mg/dl, triglycerides 139.6 mg/dl, HDL-cholesterol 39.0 mg/dl, non-HDL-cholesterol 159.5 mg/dl and LDL-cholesterol 131.5 mg/dl. The most frequent abnormality was HDL-cholesterol below 40 mg/dl with a prevalence of 60.5% (95%CI 58.2-62.8%). Hypercholesterolemia (> 200 mg/dl) had a frequency of abnormality of 43.6% (95%CI 41.4-46.0%). Only 8.6% of the hypercholesterolemic subjects knew their diagnosis. Hypertriglyceridemia (>or= 150 mg/dl) was observed in 31.5% (IC 95% 29.3-33.9%) of the population. The ENSANUT 2006 data confirm that the prevalence of hypoalphalipoproteinemia and other forms of dyslipidemia in Mexican adults is very high.

The prevalence of diabetes is increasing worldwide. The objective of this study is to estimate the prevalence of self-reported diabetes in Brazilian adults and to describe its population correlates as well as the clinical characteristics of the reported cases. We analyzed basic and supplementary data of 54.144 subjects participating in VIGITEL 2011 (Surveillance System for Risk and Protective Factors for Chronic Diseases), a telephone survey based on a probabilistic sample of subjects ≥ 18 years old residing in Brazilian state capitals and the Federal District. Estimates reported are weighted so as to represent the surveyed population. The prevalence of self-reported diabetes was 6.3% (95% CI 5.9-6.7), increasing markedly with age and nutritional status, and decreasing with level of education. Prevalence was higher among those self-declaring their race/color as black. Most cases (90%) reported the diagnosis being made at 35 years or older. The vast majority (99.8%) of self-reported cases informed having previously performed at least one glucose test, and 76% of those not reporting diabetes also informed having previously performed glucose testing. Most cases (92.6%) reported following some form of diabetes treatment, 79% taking medication. The estimated prevalence of known diabetes found, 6.3%, is consistent with estimates given by international summaries. The additional data collected in VIGITEL 2011 regarding previous glucose testing and current treatment support the use of telephone-based information to monitor the prevalence of known diabetes in Brazilian capitals.

Globally, per-capita, South Africa reports a disproportionately high number of cases of multidrug-resistant (MDR) tuberculosis and extensively drug-resistant (XDR) tuberculosis. We sought to estimate the prevalence of resistance to tuberculosis drugs in newly diagnosed and retreated patients with tuberculosis provincially and nationally, and compared these with the 2001-02 estimates. A cross-sectional survey was done between June 15, 2012-June 14, 2014, using population proportionate randomised cluster sampling in the nine provinces in South Africa. 343 clusters were included, ranging between 31 and 48 per province. A patient was eligible for inclusion in the survey if he or she presented as a presumptive case during the intake period at a drug resistance survey enrolling facility. Consenting participants (≥18 years old) completed a questionnaire and had a sputum sample tested for resistance to first-line and second-line drugs. Analysis was by logistic regression with robust SEs, inverse probability weighted against routine data, and estimates were derived using a random effects model. 101 422 participants were tested in 2012-14. Nationally, the prevalence of MDR tuberculosis was 2·1% (95% CI 1·5-2·7) among new tuberculosis cases and 4·6% (3·2-6·0) among retreatment cases. The provincial point prevalence of MDR tuberculosis ranged between 1·6% (95% CI 0·9-2·9) and 5·1% (3·7-7·0). Overall, the prevalence of rifampicin-resistant tuberculosis (4·6%, 95% CI 3·5-5·7) was higher than the prevalence of MDR tuberculosis (2·8%, 2·0-3·6; p=0·01). Comparing the current survey with the previous (2001-02) survey, the overall MDR tuberculosis prevalence was 2·8% versus 2·9% and prevalance of rifampicin-resistant tuberculosis was 3·4% versus 1·8%, respectively. The prevalence of isoniazid mono-resistant tuberculosis was above 5% in all provinces. The prevalence of ethionamide and pyrazinamide resistance among MDR tuberculosis cases was 44·7% (95% CI 25

Learning lessons from field surveys in humanitarian contexts: a case study of field surveys conducted in North Kivu, DRC 2006-2008

Full Text Available Abstract Survey estimates of mortality and malnutrition are commonly used to guide humanitarian decision-making. Currently, different methods of conducting field surveys are the subject of debate among epidemiologists. Beyond the technical arguments, decision makers may find it difficult to conceptualize what the estimates actually mean. For instance, what makes this particular situation an emergency? And how should the operational response be adapted accordingly. This brings into question not only the quality of the survey methodology, but also the difficulties epidemiologists face in interpreting results and selecting the most important information to guide operations. As a case study, we reviewed mortality and nutritional surveys conducted in North Kivu, Democratic Republic of Congo (DRC published from January 2006 to January 2009. We performed a PubMed/Medline search for published articles and scanned publicly available humanitarian databases and clearinghouses for grey literature. To evaluate the surveys, we developed minimum reporting criteria based on available guidelines and selected peer-review articles. We identified 38 reports through our search strategy; three surveys met our inclusion criteria. The surveys varied in methodological quality. Reporting against minimum criteria was generally good, but presentation of ethical procedures, raw data and survey limitations were missed in all surveys. All surveys also failed to consider contextual factors important for data interpretation. From this review, we conclude that mechanisms to ensure sound survey design and conduct must be implemented by operational organisations to improve data quality and reporting. Training in data interpretation would also be useful. Novel survey methods should be trialled and prospective data gathering (surveillance employed wherever feasible.

Full Text Available Abstract Background Developing countries are undergoing an epidemiological transition, from Communicable or Infectious to 'Non-Communicable' diseases (NCDs, such that cardiovascular disease, chronic respiratory diseases, cancer, and diabetes were responsible for 60% of all deaths globally in 2005, with more than 75% of these deaths occurring in developing countries. A survey was conducted to determine among other objectives the prevalence of diabetes and its association with physical fitness and biological factors. Methods A cross sectional study utilizing a modified World Health Organization's STEPwise approach to surveillance of NCDs was conducted in Lusaka district, Zambia. A multi-stage cluster sampling technique was used to select study participants of age 25 years or older. All eligible members of a household that was selected were invited to participate in the study. Unadjusted odds ratios (OR, and adjusted odds ratios (AOR together with their 95% Confidence Intervals (CI were obtained using Complex samples logistic regression Results A total of 1928 individuals participated in the survey, of which 33.0% were males. About half of the participants were of age 25-34 years (53.2%, and about a third of the respondents had attained secondary level of education (35.8%. The combined prevalence for impaired glucose level or diabetes was 4.0%. Age and mild hypertension were significantly associated with impaired levels of glucose or diabetes. Compared to participants in the age group 25-34 years, older participants were more likely to have impaired glucose level or diabetes (AOR = 2.49 (95%CI [1.35, 2.92] for 35-44 years age group, and AOR = 3.80 (95%CI [2.00, 7.23] for 45 + years age group. Mild hypertension was associated with impaired glucose level or diabetes (AOR = 2.57 (95%CI [1.44, 4.57]. Conclusions The prevalence of diabetes in Lusaka district has not reached an alarming level and it is now that interventions targeting the younger age

To effectively shape mental healthcare policy in modern-day China, up-to-date epidemiological data on mental disorders is needed. The objective was to estimate the prevalence, age-of-onset (AOO) and sociodemographic correlates of mental disorders in a representative household sample of the general population (age ⩾ 18) in the Tianjin Municipality in China. Data came from the Tianjin Mental health Survey (TJMHS), which was conducted between July 2011 and March 2012 using a two-phase design. 11 748 individuals were screened with an expanded version of the General Health Questionnaire and 4438 subjects were selected for a diagnostic interview by a psychiatrist, using the Structured Clinical Interview for the Diagnostic and Statistical Manual - fourth edition (SCID). The lifetime and 1-month prevalence of any mental disorder were 23.6% and 12.8%, respectively. Mood disorders (lifetime: 9.3%; 1-month: 3.9%), anxiety disorders (lifetime: 4.5% 1-month: 3.1%) and substance-use disorders (lifetime: 8.8%; 1-month: 3.5%) were most prevalent. The median AOO ranged from 25 years [interquartile range (IQR): 23-32] for substance-use disorders to 36 years (IQR: 24-50) for mood disorders. Not being married, non-immigrant status (i.e. local 'Hukou'), being a farmer, having mental disorder. Results from the current survey indicate that mental disorders are steadily reported more commonly in rapidly-developing urban China. Several interesting sociodemographic correlates were observed (e.g. male gender and non-immigrant status) that warrant further investigation and could be used to profile persons in need of preventive intervention.

Conduction Mechanism of Valence Change Resistive Switching Memory: A Survey

Directory of Open Access Journals (Sweden)

Ee Wah Lim

2015-09-01

Full Text Available Resistive switching effect in transition metal oxide (TMO based material is often associated with the valence change mechanism (VCM. Typical modeling of valence change resistive switching memory consists of three closely related phenomena, i.e., conductive filament (CF geometry evolution, conduction mechanism and temperature dynamic evolution. It is widely agreed that the electrochemical reduction-oxidation (redox process and oxygen vacancies migration plays an essential role in the CF forming and rupture process. However, the conduction mechanism of resistive switching memory varies considerably depending on the material used in the dielectric layer and selection of electrodes. Among the popular observations are the Poole-Frenkel emission, Schottky emission, space-charge-limited conduction (SCLC, trap-assisted tunneling (TAT and hopping conduction. In this article, we will conduct a survey on several published valence change resistive switching memories with a particular interest in the I-V characteristic and the corresponding conduction mechanism.

Fatigue has a profound impact on patients with spinal cord injury (SCI), but only limited treatments are available. The aim of this study was to determine the prevalence of fatigue in SCI and its association with clinical and demographic factors. We used an internet-based survey and a face-to-face interview to estimate the prevalence of fatigue in a SCI population. Fatigue was measured using the Fatigue Severity Scale (FSS). Clinically significant fatigue was defined as FSS scores greater than or equal to four. A total of 253 participants with SCI were included in the study. Clinically significant fatigue was present in one third of our sample. There was no relationship between fatigue and injury level or completeness. We found significant correlations between depression, pain, and level of injury. The relation of fatigue with completeness of injury and spasticity is less clear. Moreover, the online survey and the standard face-to-face interview showed similar results concerning fatigue evaluation. Several factors may contribute to fatigue, however. Future studies should be conducted to clarify which are the most relevant ones and, if possible, to determine which factors are modifiable.

To examine trends in the prevalence of domestic violence since 1997, 1 year prior to the introduction of legislative countermeasures and accompanying services in South Korea, and to analyze what socio-demographic characteristics of perpetrators contribute to spousal violence and whether there were any changes in risk factors over time. This study used two sets of nationally representative household samples: married or cohabiting couples of 1,540 from the 1999 national survey and 3,269 from the 2010 National Survey of Domestic Violence. Frequency analysis was used to measure the prevalence of intimate partner violence (IPV), and cross-tabulation, correlation, and logistic regression analyses were used to look for socio-demographic risk factors of spousal physical violence and patterns of change over time. The frequency analysis showed that the IPV prevalence dropped by approximately 50%, from 34.1% in 1999 to 16.5% in 2010, though it was still higher than many other countries. The cross-tabulation and logistic regression analyses suggested that men with low socio-demographic characteristics were generally more violent, though this tendency did not apply to women. Instead, younger women seemed to be more violent than older women. Last, different levels of household income were associated with different levels of IPV in 2010, but no linear trend was detected. In this study, IPV prevalence trends and risk factors of two different time periods were discussed to provide implications for tackling the IPV problem. Future countermeasures must build on understanding about men with low socio-demographic status and younger women, who were more violent in marital relationships. © The Author(s) 2015.

Hypertension is the most common non-communicable disease and risk factor for heart failure, stroke, chronic kidney disease and ischemic heart disease in sub-Saharan Africa. Few population-based studies have been conducted recently in Nigeria and, in Abia State, no previous study has been conducted on the prevalence and correlates of hypertension among the populace. The purpose of our study was, therefore, to determine the prevalence and determinants of high blood pressure in Abia State, southeastern Nigeria. We hypothesise that high blood pressure burden is high in Abia State. The study was a community based cross-sectional house-to-house survey aimed at ascertaining the burden/prevalence of hypertension in the state as well as identifying related risk factors associated with them. The study was conducted in rural and urban communities in Abia State, Nigeria. Participants in the study were men and women aged > or =15 years and were recruited from the three senatorial zones in the state. A total of 2,999 respondents were selected for the survey and, 2,983 consented to be interviewed giving a response rate of 99.5%. The data for 2,928 participants were suitable for analysis. Of these, 1,399 (47.8%) were men. The mean age of the population was 41.7 +/- 18.5 years (range 18-96 years). About 54% of the population were < or =40 years. Ninety percent had at least primary education with about 47% having completed secondary education. Expectedly, 96% of the respondents were Ibos, the predominant tribe in the southeastern part of the country. Women had significantly higher BMI than the men. Similarly, waist circumference was also larger in women but waist-to-hip ratio was only significantly higher in women in the urban areas compared to those in rural areas. Thirty-one percent of all participants had systolic hypertension (33.5% in men and 30.5% in women). This sex difference was statistically different in the urban area. On the other hand, diastolic hypertension was 22

Full Text Available Abstract Background Birth Defects are a series of diseases that seriously affect children's health. Birth defects are generally caused by several interrelated factors. The aims of the article is to estimate the prevalence rate and types of birth defects in Inner Mongolia, China, to compare socio-demographic characteristics among the children with birth defects and to analyze the association between risk factors and birth defects. Methods Data used in this study were obtained through baseline survey of Inner Mongolia Birth Defects Program, a population-based survey conducted from 2005 to 2008. The survey used cluster sampling method in all 12 administrative districts of Inner Mongolia. Sampling size is calculated according to local population size at a certain percentage. All live births, stillbirths and abortions born from October 2005 to September 2008, whose families lived in Inner Mongolia at least one year, were included. The cases of birth defects were diagnosed by the clinical doctors according to their experiences with further laboratory tests if needed. The inclusion criteria of the cases that had already dead were decided according to death records available at local cites. We calculated prevalence rate and 95% confidence intervals of different groups. Outcome variable was the occurrence of birth defects and associations between risk factors and birth defects were analyzed by using Poisson regression analysis. Results 976 children with birth defects were diagnosed. The prevalence rate of birth defects was 156.1 per 10000 births (95%CI: 146.3-165.8. The prevalence rate of neural tube defect (20.1 per 10000 births including anencephaly(6.9 per 10000, spina bifida (10.6 per 10000, and encephalocele (2.7 per 10000 was the highest, followed by congenital heart disease (17.1 per 10000. The relative risk (RR for maternal age less than 25 was 2.22 (95%CI: 2.05, 2.41. The RR of the ethnic Mongols was lower than Han Chinese (RR: 0.84; 95%CI: 0

As a common tool for subsurface archaeological prospection, ground penetrating radar (GPR) is a useful method for increasing the efficiency of archaeological excavations. Archaeological sites are often temporally and financially constrained, therefore having limited ability to reschedule surveys compromised by weather. Furthermore, electromagnetic GPR surveys are especially sensitive to variations in water content, soil type, and site-specific interference. In this work, GPR scans of a partially excavated Roman villa consisting of different construction materials and phases (limestone, andesite, brick) in central Romania are compared. Surveys were conducted with a 500 MHz GPR antenna in both dry (pre-rain event) and wet (post-rain event) conditions. Especially in time or depth slices, wet surveys present additional archaeological features that are not present or clear in the standard dry conditions, while simultaneously masking the clutter present in those scans. When dry, the limestone has a similar dielectric constant to the soil and does not provide enough contrast in electromagnetic properties for strong reflections despite the significant difference in their physical properties. Following precipitation, however, the electromagnetic properties of these two materials is dominated by their respective water content and the contrast is enhanced. For this reason, the wet surveys are particularly necessary for revealing reflections from the limestone features often invisible in dry surveys. GPR surveys conducted in variable environmental conditions provide unique archaeological information, with potential near-surface geophysical applications in nondestructive material characterization and identification.

Full Text Available The prevalence of diabetes is increasing worldwide. The objective of this study is to estimate the prevalence of self-reported diabetes in Brazilian adults and to describe its population correlates as well as the clinical characteristics of the reported cases.We analyzed basic and supplementary data of 54.144 subjects participating in VIGITEL 2011 (Surveillance System for Risk and Protective Factors for Chronic Diseases, a telephone survey based on a probabilistic sample of subjects ≥ 18 years old residing in Brazilian state capitals and the Federal District. Estimates reported are weighted so as to represent the surveyed population.The prevalence of self-reported diabetes was 6.3% (95% CI 5.9-6.7, increasing markedly with age and nutritional status, and decreasing with level of education. Prevalence was higher among those self-declaring their race/color as black. Most cases (90% reported the diagnosis being made at 35 years or older. The vast majority (99.8% of self-reported cases informed having previously performed at least one glucose test, and 76% of those not reporting diabetes also informed having previously performed glucose testing. Most cases (92.6% reported following some form of diabetes treatment, 79% taking medication.The estimated prevalence of known diabetes found, 6.3%, is consistent with estimates given by international summaries. The additional data collected in VIGITEL 2011 regarding previous glucose testing and current treatment support the use of telephone-based information to monitor the prevalence of known diabetes in Brazilian capitals.

A survey on 10.000 adults between the age of 20 and 79 years out of a total population of 66.186 persons in rural settlements under the inrisduction of Union Territory of Chandigarh between June 1993 to June 1995 was conducted to find out the prevalence and various causes of vertigo. In general community, in rural population, we found that more people suffer from non-otologic vertigo rather than otologic vertigo. We found overall prevalence of vertigo in rural adult community to be 0.71%. Vertigo secondary to cardiovascular disease was most common and prevalent in 0.32% of population. Neurologic disease accounted for vertigo in 0.14%, metabolic disease in 0.09% and otologic disease 0.08%. Miscellaneous disorders were present in remaining 0.08% of population studied. To the best of our knowledge this study represents the first population based survey of prevalence of various causes of vertigo in general community in adult rural population.

In Bangladesh DOTS has been provided free of charge since 1993, yet information on access to TB services by different population group is not well documented. The objective of this study was to assess and compare the socio economic position (SEP) of actively detected cases from the community and the cases being routinely detected under National Tuberculosis Control Programme (NTP) in Bangladesh. SEP was assessed by validated asset item for each of the 21,427 households included in the national tuberculosis prevalence survey 2007-2009. A principal component analysis generated household scores and categorized in quartiles. The distribution of 33 actively identified cases was compared with the 240 NTP cases over the identical SEP quartiles to evaluate access to TB services by different groups of the population. The population prevalence of tuberculosis was 5 times higher in the lowest quartiles of population (95.4, 95% CI: 48.0-189.7) to highest quartile population (19.5, 95% CI: 6.9-55.0). Among the 33 cases detected during survey, 25 (75.8%) were from lower two quartiles, and the rest 8 (24.3%) were from upper two quartiles. Among TB cases detected passively under NTP, more than half of them 137 (57.1%) were from uppermost two quartiles, 98 (41%) from the second quartile, and 5 (2%) in the lowest quartile of the population. This distribution is not affected when adjusted for other factors or interactions among them. The findings indicate that despite availability free of charge, DOTS is not equally accessed by the poorer sections of the population. However, these figures should be interpreted with caution since there is a need for additional studies that assess in-depth poverty indicators and its determinants in relation to access of the TB services provided in Bangladesh.

To compare the prevalence estimates of selected health indicators and chronic diseases or conditions among three national health surveys in the United States. Data from adults aged 18 years or older who participated in the Behavioral Risk Factor Surveillance System (BRFSS) in 2007 and 2008 (n=807,524), the National Health Interview Survey (NHIS) in 2007 and 2008 (n=44,262), and the National Health and Nutrition Examination Survey (NHANES) during 2007 and 2008 (n=5871) were analyzed. The prevalence estimates of current smoking, obesity, hypertension, and no health insurance were similar across the three surveys, with absolute differences ranging from 0.7% to 3.9% (relative differences: 2.3% to 20.2%). The prevalence estimate of poor or fair health from BRFSS was similar to that from NHANES, but higher than that from NHIS. The prevalence estimates of diabetes, coronary heart disease, and stroke were similar across the three surveys, with absolute differences ranging from 0.0% to 0.8% (relative differences: 0.2% to 17.1%). While the BRFSS continues to provide invaluable health information at state and local level, it is reassuring to observe consistency in the prevalence estimates of key health indicators of similar caliber between BRFSS and other national surveys.

Previous studies have reported a possibly increasing HIV prevalence among men who have sex with men (MSM) in China. However there have been limited systematic analyses of existing surveillance data to learn the trend of HIV prevalence and factors driving the trend. The aims of this study were to examine the trend of HIV prevalence among MSM in Guangzhou and to explore the role of unprotected anal intercourse (UAI) in the trend. Snow-ball sampling was applied in the subject recruitment for the annual serological and behavioral surveys among MSM from 2008 to 2013. Data collected in the behavioral survey include demographic information, HIV related sexual behavior with men and women, access to HIV prevention services, and symptoms of sexually transmitted infections. Chi-square test was used to analyze the trend of HIV prevalence. Multivariate logistic regression was conducted to test the factors associated with HIV infection. HIV prevalence increased significantly from 5.0% in 2008 to 11.4% in 2013 while syphilis prevalence decreased from 17.4% to 3.3% in the same period. UAI rates were high and stable in every single year, ranging from 54.5% to 62.0%. Those who were having UAI (OR = 1.80, 95% confidence interval (CI): 1.26-2.58), being migrants, having more than 10 partners, and infected with syphilis had higher risk for HIV infection. HIV epidemic is expanding in Guangzhou. The persistently high UAI may have played a major role in the increasing trend of HIV prevalence. Targeted prevention program should be conducted among MSM who are migrants, low educational level, syphilis infected, or having multiple partners to encourage HIV test and change UAI behavior. The general high UAI calls for tailored intervention program to promote healthy culture and form a safe sex social norm in the MSM community.

Respondent-driven sampling (RDS) is a form of chain-referral sampling that is increasingly being used for HIV behavioural surveillance. When used for surveillance purposes, a sampling method should be relatively inexpensive and simple to operate. This study examined whether an RDS survey of people who inject drugs (PWID) in Sydney, Australia, could be successfully conducted through the use of minimal and existing resources. The RDS survey was conducted on the premises of a local needle and syringe program (NSP) with some adjustments to take into account the constraints of existing resources. The impact of the survey on clients and on staff was examined by summarizing NSP service data and by conducting post-survey discussions with NSP staff. From November 2009 till March 2010, 261 participants were recruited in 16 waves. A significant increase was found in the number of services provided by the NSP during and after data collection. Generally, staff felt that the survey had a positive impact by exposing a broader group of people to the NSP. However, conducting the survey may have led to privacy issues for NSP clients due to an increased number of people gathering around the NSP. This study shows that RDS can be conducted with the use of minimal and existing resources under certain conditions (e.g., use of a self-administered questionnaire and no biological samples taken). A more detailed cost-utility analysis is needed to determine whether RDS' advantages outweigh potential challenges when compared to simpler and less costly convenience methods.

The aim of this article was to estimate HIV prevalence and the factors associated with HIV seropositivity in the population living and working at the informal artisanal small-scale gold mining (IASGM) site of Kokoyo in Mali, using data from the Sanu Gundo survey. Our main hypothesis was that HIV prevalence is higher in the context of IASGM than in the country as a whole. The ANRS-12339 Sanu Gundo was a cross-sectional survey conducted in December 2015. The quantitative survey consisted of face-to-face administration of questionnaires. Five focus groups were conducted for the qualitative survey. HIV prevalence was calculated for the sample, and according to the type of activity performed in IASGM. The IASGM site of Kokoyo, one of the largest sites in Mali (between 6000 and 1000 people). 224 respondents: 37.5% were gold-diggers, 33% retail traders, 6.7% tombolomas (ie, traditional guards) and 9% female sex workers. The remaining 13.8% reported another activity (mainly street vending). HIV prevalence and HIV prevalence according to subgroup, as defined by their activity at the Kokoyo IASGM. A probit logistic regression was implemented to estimate the characteristics associated with HIV seropositivity. HIV prevalence for the total sample was 8% (95% CI 7.7% to 8.3%), which is much higher than the 2015 national prevalence of 1.3%Joint United Nations Programme on HIV/AIDS (UNAIDS). The probability of HIV seropositivity was 7.8% (p=0.037) higher for female non-sex workers than for any other category, and this probability increased significantly with age. Qualitative data revealed the non-systematic use of condoms with sex workers; and long distance from health services was the main barrier to accessing care. Integrated policymaking should pay special attention to infectious diseases among populations in IASGM zones. Bringing information/prevention activities closer to people working in gold mining zones is an urgent public health action. © Article author(s) (or their

Background and Objectives The hearing loss of workers can occur when they are affected by age, otologic disease, and work-related risks such as noise and chemicals. Based on the Korean Working Conditions Survey (KWCS) in 2010, this research aimed to estimate the prevalence rate of hearing loss and to identify the risk factors affecting its occurrence. Subjects and Methods The subjects were 10019 employees who completed an interview conducted as part of KWCS in 2010. The prevalence rate of hearing loss according to sex, age, education, income, smoking, drinking, hypertension, industrial type, occupations, employment status, working period, and hazards at the workplace were assessed. The factors that could affect the occurrence of hearing loss were investigated based on a logistic regression analysis. Results The prevalence rate of hearing loss was 2.7%. In a logistic multivariate analysis, sex, age, occupations, working period, noise, and exposure to chemicals showed statistically significant correlations to the occurrence of hearing loss. The adjusted odd ratios were as follows: 1.74 [95% confidence interval (CI), 1.03-2.96] for males, 2.11 (95% CI, 1.14-3.89) for those in their 40s, 2.24 (95% CI, 1.19-4.20) for those in their 50s, 2.21 (95% CI, 1.18-4.15) for manage/professional works, 2.73 (95% CI, 1.69-4.41) for manufacturing, 2.07 (95% CI, 1.36-3.15) for those who have worked for more than 20 years, 1.72 (95% CI, 1.14-2.58) for noise exposure, 1.53 (95% CI, 1.02-2.30) for vibration exposure and 1.58 (95% CI, 1.11-2.24) for chemical exposure. Conclusions The overall occupational and non-occupational risk factors related to employees' hearing loss were reviewed. In addition to the exposure to noise, occupational risks of hearing loss, such as isolated exposure to vibration and chemicals, and combined exposure to noise and these hazards, were identified. Multiple exposure to hazards, along with prolonged noise exposure increased the risk of hearing loss. PMID

Bullying has public health importance. It has been reported that both the victims and perpetrators of bullying are more likely to have suicidal ideation and other suicidal behaviours. Moreover, bullying can be a precursor for school violence and can contribute to poor academic performance. The purpose of the study was to raise awareness on the subject in China. We, therefore conducted an analysis of secondary data to determine the prevalence and correlates of having been bullied among in-school adolescents. The data was taken from the Beijing Global School-Based Health Survey conducted in 2003. A weighted analysis to reduce bias due to differing patterns of non-response was conducted using statistical software (SPSS version 14.0). We conducted a backward logistic regression analysis to determine independent predictors for being bullied. Out of a total of 2,348 in-school adolescents who participated in the survey, 20% (23% males, and 17% females) reported having been bullied. Risk factors for having been bullied were loneliness (adjusted odds ratio (AOR) = 1.44; 95% confidence interval (CI) 1.42-1.45), being worried (AOR = 1.30; 95% CI 1.29-1.32), being sad or having feelings of hopelessness (AOR = 1.21; 95% CI 1.19-1.22), smoking cigarettes (AOR = 1.09; 95% CI 1.08-1.11), drinking alcohol (AOR = 1.31; 95% CI 1.29-1.32), and being truant (AOR = 1.24; 95% CI 1.22-1.27). Meanwhile protective factors were having close friends (AOR = 0.84; 95% CI 0.83-0.86), receiving parental supervision (AOR = 0.80; 95% CI 0.80-0.81), and ever been drunk (AOR = 0.86; 95% CI 0.84-0.87). We believe the results of this study will raise awareness among school health practitioners and administrators, paediatric psychiatrists and psychologists on the prevalence and correlates of bullying among adolescents in Beijing, China.

Kundel, Harold L.

2000-04-01

A survey of 12 studies of lung cancer detection with cancer prevalence ranging from 0.9 to 476 cancers per 1000 showed that the unit-slope index of detectability, d', decreased from a high value of 3.9 at low prevalence to 1.4 at high prevalence. A proposed explanation is that the readers are operating on an ROC curve with a slope that is less than unity approximating 0.6. On such a curve, a shift to more stringent criteria that occurs with decreasing prevalence in order to minimize false positives, would result in a increased unity- slope d'.

To systematically review surveys of 12-month prevalence of homeopathy use by the general population worldwide. Studies were identified via database searches to October 2015. Study quality was assessed using a six-item tool. All estimates were in the context of a survey which also reported prevalence of any complementary and alternative medicine use. A total of 36 surveys were included. Of these, 67% met four of six quality criteria. Twelve-month prevalence of treatment by a homeopath was reported in 24 surveys of adults (median 1.5%, range 0.2-8.2%). Estimates for children were similar to those for adults. Rates in the USA, UK, Australia and Canada all ranged from 0.2% to 2.9% and remained stable over the years surveyed (1986-2012). Twelve-month prevalence of all use of homeopathy (purchase of over-the-counter homeopathic medicines and treatment by a homeopath) was reported in 10 surveys of adults (median 3.9%, range 0.7-9.8%) while a further 11 surveys which did not define the type of homeopathy use reported similar data. Rates in the USA and Australia ranged from 1.7% to 4.4% and remained stable over the years surveyed. The highest use was reported by a survey in Switzerland where homeopathy is covered by mandatory health insurance. This review summarises 12-month prevalence of homeopathy use from surveys conducted in eleven countries (USA, UK, Australia, Israel, Canada, Switzerland, Norway, Germany, South Korea, Japan and Singapore). Each year a small but significant percentage of these general populations use homeopathy. This includes visits to homeopaths as well as purchase of over-the-counter homeopathic medicines.

Full Text Available OBJECTIVES: To estimate prevalence of chronic conditions among patients seeing a general practitioner (GP, patients attending general practice at least once in a year, and the Australian population. DESIGN SETTING AND PARTICIPANTS: A sub-study of the BEACH (Bettering the Evaluation and Care of Health program, a continuous national study of general practice activity conducted between July 2008 and May 2009. Each of 290 GPs provided data for about 30 consecutive patients (total 8,707 indicating diagnosed chronic conditions, using their knowledge of the patient, patient self-report, and patient's health record. MAIN OUTCOME MEASURES: Estimates of prevalence of chronic conditions among patients surveyed, adjusted prevalence in patients who attended general practice at least once that year, and national population prevalence. RESULTS: Two-thirds (66.3% of patients surveyed had at least one chronic condition: most prevalent being hypertension (26.6%, hyperlipidaemia (18.5%, osteoarthritis (17.8%, depression (13.7%, gastro-oesophageal reflux disease (11.6%, asthma (9.5% and Type 2 diabetes (8.3%. For patients who attended general practice at least once, we estimated 58.8% had at least one chronic condition. After further adjustment we estimated 50.8% of the Australian population had at least one chronic condition: hypertension (17.4%, hyperlipidaemia (12.7%, osteoarthritis (11.1%, depression (10.5% and asthma (8.0% being most prevalent. CONCLUSIONS: This study used GPs to gather information from their knowledge, the patient, and health records, to provide prevalence estimates that overcome weaknesses of studies using patient self-report or health record audit alone. Our results facilitate examination of primary care resource use in management of chronic conditions and measurement of prevalence of multimorbidity in Australia.

Objective Assess the national prevalence of current workplace exposure to potential skin hazards, secondhand smoke (SHS), and outdoor work among various industry and occupation groups. Also, assess the national prevalence of chronic workplace exposure to vapors, gas, dust, and fumes (VGDF) among these groups. Methods Data were obtained from the 2010 National Health Interview Survey (NHIS). NHIS is a multistage probability sample survey of the civilian non-institutionalized population of the US. Prevalence rates and their variances were calculated using SUDAAN to account for the complex NHIS sample design. Results The data for 2010 were available for 17,524 adults who worked in the 12 months that preceded interview. The highest prevalence rates of hazardous workplace exposures were typically in agriculture, mining, and construction. The prevalence rate of frequent handling of or skin contact with chemicals, and of non-smokers frequently exposed to SHS at work was highest in mining and construction. Outdoor work was most common in agriculture (85%), construction (73%), and mining (65%). Finally, frequent occupational exposure to VGDF was most common among mining (67%), agriculture (53%), and construction workers (51%). Conclusion We identified industries and occupations with the highest prevalence of potentially hazardous workplace exposures, and provided targets for investigation and intervention activities.

The course of conduct disorder (CD) is heterogeneous. Moffitt proposed the heuristic of life course persistent (LCP) and adolescence limited (AL) to differentiate etiologically distinct forms of antisocial behavior (AB), each with distinct predictors and consequences, although a few studies have assessed this demarcation within the context of CD. The objective of this study was to apply Moffitt's taxonomy in a nationally representative US sample to investigate the prevalence, predictors, and outcomes of LCP and AL CD. Data come from the Collaborative Psychiatric Epidemiology Studies, a set of population-based nationally representative cross-sectional surveys (N = 20,130). Predictors included harsh discipline, maternal and paternal closeness, poverty in childhood, history of learning disability, parental deviance, and nativity. Outcomes included substance use, employment status, education attainment, marital status, income level, and self-rated mental and physical health. The prevalence of LCP and AL CD was 0.5 and 4.6%, respectively, for females, and 1.9 and 5.1%, respectively, for males. Low childhood SES [Odds Ratio (OR) = 3.49], lack of maternal closeness (OR = 2.50), and history of harsh discipline (OR = 2.17) increased odds of LCP group membership. The LCP group had higher odds of developing substance use disorders (OR = 2.00) relative to AL. LCP CD is more strongly influenced by childhood environment and confers increased odds for substance use problems in adulthood relative to AL CD.

We study Danish adult gambling behavior with an emphasis on discovering patterns relevant to public health forecasting and economic welfare assessment of policy. Methodological innovations include measurement of formative in addition to reflective constructs, estimation of prospective risk for developing gambling disorder rather than risk of being falsely negatively diagnosed, analysis with attention to sample weights and correction for sample selection bias, estimation of the impact of trigger questions on prevalence estimates and sample characteristics, and distinguishing between total and marginal effects of risk-indicating factors. The most significant novelty in our design is that nobody was excluded on the basis of their response to a 'trigger' or 'gateway' question about previous gambling history. Our sample consists of 8405 adult Danes. We administered the Focal Adult Gambling Screen to all subjects and estimate prospective risk for disordered gambling. We find that 87.6% of the population is indicated for no detectable risk, 5.4% is indicated for early risk, 1.7% is indicated for intermediate risk, 2.6% is indicated for advanced risk, and 2.6% is indicated for disordered gambling. Correcting for sample weights and controlling for sample selection has a significant effect on prevalence rates. Although these estimates of the 'at risk' fraction of the population are significantly higher than conventionally reported, we infer a significant decrease in overall prevalence rates of detectable risk with these corrections, since gambling behavior is positively correlated with the decision to participate in gambling surveys. We also find that imposing a threshold gambling history leads to underestimation of the prevalence of gambling problems.

In recent years, there has been an increase in emergence and use of novel psychoactive substances (NPS) in the US and worldwide. However, there is little published epidemiological survey data estimating the prevalence of use in the US. Data on self-reported NPS use came from the National Survey of Drug Use and Health (2009-2013), a national representative sample of non-institutionalized individuals in the US. Subjects were asked to provide names of (non-traditional) drugs they used that they were not specifically asked about. We examined lifetime prevalence and sociodemographic correlates of self-reported use of new and uncommon synthetic drugs (NPS) among subjects ages 12-34-years-old. 1.2% of subjects self-reported any use of the 57 NPS we examined. Use of psychedelic tryptamines (primarily DMT) was most common, followed by psychedelic phenethylamines (e.g., 2C series) and synthetic cannabinoids. Prevalence of self-reported use of NPS increased from 2009 to 2013 and use was most common among males, whites, older subjects, those of lower income, and among those residing in cities. Lifetime use of various other illicit drugs (e.g., LSD, cocaine, ecstasy/MDMA) was highly prevalent among NPS users. This the first study reporting on use of a variety of NPS in a nationally representative US sample; however, use appears to be underreported as other national data suggest higher rates of NPS (e.g., synthetic cannabinoid) use. Developing more adaptable survey tools and systematically assessing NPS use would allow researchers to ask about hundreds of NPS and improve reporting as new drugs continue to rapidly emerge.

As part of the Third Healthcare Associated Infection (HCAI) Prevalence Survey of the United Kingdom and Ireland, HCAI point prevalence surveys were carried out in Northern Ireland (NI) and the Republic of Ireland (RoI). Here we explore the potential benefits of comparing results from two countries with different healthcare systems, which employed similar methodologies and identical HCAI definitions. Forty-four acute adult hospitals in the RoI and 15 in NI participated with a total of 11 185 patients surveyed (NI 3644 patients and RoI 7541). The overall HCAI prevalence was 5.4 and 4.9 in NI and the RoI, respectively. There was no significant difference in prevalence rates of HCAI, device-related HCAI or HCAI associated with bloodstream infection but there was a difference in meticillin-resistant Staphylococcus aureus-related HCAI (P = 0.02) between the two countries. There were significantly more urinary tract infections and Clostridium difficile infections recorded in NI (P = 0.002 and P < 0.001). HCAIs were more prevalent in patients aged >65 years and in the intensive care unit in both countries. HCAIs were also more prevalent if patients were mechanically ventilated, had had recent non-implant surgery (RoI) or had more recorded HCAI risk factors. This is the first time that HCAI prevalence rates have been directly compared between NI and the RoI. By closely examining similarities and differences between HCAI prevalence rates in both countries it is hoped that this will influence healthcare planning and at the same time reassure the public that HCAI is important and that measures are being taken to combat it.

To determine the magnitude and determinants of the ratio between prevalence of low vision and prevalence of blindness in rapid assessment of avoidable blindness (RAAB) surveys globally. Standard RAAB reports were downloaded from the repository or requested from principal investigators. Potential predictor variables included prevalence of uncorrected refractive error (URE) as well as gross domestic product (GDP) per capita, health expenditure per capita of the country across World Bank regions. Univariate and multivariate linear regression were used to investigate the correlation between potential predictor variables and the ratio. The results of 94 surveys from 43 countries showed that the ratio ranged from 1.35 in Mozambique to 11.03 in India with a median value of 3.90 (Interquartile range 3.06;5.38). Univariate regression analysis showed that prevalence of URE (p = 0.04), logarithm of GDP per capita (p = 0.01) and logarithm of health expenditure per capita (p = 0.03) were significantly associated with the higher ratio. However, only prevalence of URE was found to be significant in multivariate regression analysis (p = 0.03). There is a wide variation in the ratio of the prevalence of low vision to the prevalence of blindness. Eye care service utilization indicators such as the prevalence of URE may explain some of the variation across the regions.

Full Text Available Recreational sun exposure accounts for a large number of acute and chronic dermatological diseases, including skin cancer. This study aimed at estimating the one-year prevalence of sun exposure and skin health-associated knowledge and attitudes among Austrian citizens. The population-based UVSkinRisk survey investigated a representative sample of Austrian adults using a structured questionnaire. In total, 1500 study subjects (median age 33.0 years, 50.5% females participated in this questionnaire survey. Among study participants, prevalence of sun exposure was 47%, with slightly higher rates in males (48% compared to females (46%. Younger age, lower professional category, darker skin type, motives to tan, sunbed use, sunburn, and outdoor sport activity increased the odds for prevalent sun exposure. This is the first population-based study evaluating the prevailing sun exposure and recreational habits influencing skin health among Austrian citizens. Despite public media campaigns educating on the harmful effects of sunlight exposure, we found a high prevalence of self-reported sunlight exposure. The results suggest that multifaceted socio-cultural characteristics stimulate recreational sun exposure and tanning habits. Communicating individualized Public (Skin Health messages might be the key to prevent photo-induced skin health hazards in light-skinned populations. The practical and theoretical implications of these findings are discussed.

Communication disabilities, including speech, language and voice disabilities, can significantly impact a person's quality of life, employment and health status. Despite this, little is known about the prevalence and etiology of communication disabilities in the general adult population. To assess the prevalence and etiology of communication disabilities in a nationally representative adult sample. We conducted a cross-sectional study and analyzed the responses of non-institutionalized adults to the Sample Adult Core questionnaire within the 2012 National Health Interview Survey. We used respondents' self-report of having a speech, language or voice disability within the past year and receiving a diagnosis for one of these communication disabilities, as well as the etiology of their communication disability. We additionally examined the responses by subgroups, including sex, age, race and ethnicity, and geographical area. In 2012 approximately 10% of the US adult population reported a communication disability, while only 2% of adults reported receiving a diagnosis. The rates of speech, language and voice disabilities and diagnoses varied across gender, race/ethnicity and geographic groups. The most common response for the etiology of a communication disability was "something else." Improved understanding of population prevalence and etiologies of communication disabilities will assist in appropriately directing rehabilitation and medical services; potentially reducing the burden of communication disabilities.

Lower urinary tract symptoms (LUTS) consist of storage, voiding and postmicturition symptoms and cause discomfort in approximately 15.8 to 82.0 % of adults worldwide. Despite the wide range in prevalence rates, certain potential risk factors for LUTS have been identified, advanced age being the most noted one. However, the true extent of symptom discomfort among the affected population may be underestimated because of the considerable underreporting of the problem. The objective of this study was to evaluate the prevalence, risk factors and discomfort caused by LUTS in China. This population-based, cross-sectional survey was conducted in five geographical regions of China. A stratified, clustered, systematic sample of individuals aged ≥18 years was selected to answer demographic questionnaires and the International Consultation on Incontinence Questionnaire Male/Female Lower Urinary Tract Symptoms Long Form. A total of 3,023 participants (1,551 men; 1,472 women) were included in this study, and 61.2 % (61.2 % men; 61.1 % women) reported at least one LUTS. The prevalence of storage symptoms (59.8 % men; 60.5 % women) was greater than that of voiding (23.6 % men; 8.8 % women) plus postmicturition symptoms (14.6 % men; 6.3 % women). Nocturia (58.2 % men; 56.9 % women) was the most common specific LUTS. Advanced age, alcohol consumption and smoking were risk factors for LUTS among participants of both sexes. Enlarged prostate, diabetes mellitus and lower education levels correlated positively with LUTS in men, whereas higher parity and hypertension correlated positively with LUTS in women. Subjects with LUTS had great discomfort. Nocturia was the least bothersome symptom in both sexes, whereas nocturnal enuresis and urge urinary incontinence were the most bothersome in men and women respectively. Lower urinary tract symptoms are highly prevalent in China and many known risk factors are associated with these bothersome symptoms. However, the perception of the extent

Cardiovascular diseases are becoming with their risk factors a real health problem in Africa. The objectives of this study were to assess the prevalence of risk factors for cardiovascular diseases in the general population in Saint-Louis, Senegal. This is a cross-sectional, descriptive and analytical made in May 2010, in the Senegalese aged 15, residing in the city of Saint-Louis, Senegal. A systematic random sampling and stratified cluster has been achieved. Cardiovascular risk factors for research were: hypertension, diabetes, dyslipidemia, smoking, obesity, physical inactivity and metabolic syndrome. The survey involved 1424 individuals with 983 women (69%). The average age was 43.4±17.8years. The prevalence of risk factors was: hypertension (46%), diabetes (10.4%), total cholesterol (36.3%), hyperLDLcholesterol (20.6%), obesity (body mass index≥30kg/m(2)) (23%), abdominal obesity (48.7% according to International Diabetes Federation and 33.2% according to National Cholesterol Education Program) physical inactivity (64.7%), smoking (5.8%) and metabolic syndrome (15.7%). There was predominance in women of risk factors except for smoking and diabetes. The overall cardiovascular risk was high in 24.9% according to the Framingham model, 28.8% (European Society of Hypertension) and 6.1% (SCORE). This survey found a high prevalence of cardiovascular risk factors in a general population in Senegal, predominant in women. This should lead to better develop a strategy to prevent cardiovascular diseases. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

Full Text Available Recent research has suggested a possible link between Parkinson's disease (PD and Fabry disease. To test this relationship, we administered a self-report and family history questionnaire to determine the prevalence of PD in Fabry disease patients and family members with likely pathogenic alpha-galactosidase A (GLA mutations. A total of 90 Fabry patients (77 from the online survey and 13 from the Icahn School of Medicine at Mount Sinai (ISMMS were included in the analysis. Two of the Fabry disease patients who completed the online survey were diagnosed with PD (2/90, 2.2%. Among probands older than 60, 8.3% (2/24 were diagnosed with PD. Using Kaplan Meier survival analysis, the age-specific risk of PD by age 70 was 11.1%. Family history was available on 72 Fabry families from the online study and 9 Fabry families from ISMMS. Among these 81 families, 6 (7.4% had one first degree relative who fit the criteria for a conservative diagnosis of PD. The results of this study suggest that there may be an increased risk of developing PD in individuals with GLA mutations, but these findings should be interpreted with caution given the limitations of the study design.

To describe the prevalences of asthma and rhinitis in adolescents (13-14 years of age) in the city of Fortaleza, Brazil, in 2010, comparing the results with those obtained in a prevalence survey conducted in 2006-2007. This was a cross-sectional study involving probabilistic samples of 3,015 and 3,020 adolescents in surveys conducted in 2006-2007 and 2010, respectively. The International Study of Asthma and Allergies in Childhood protocol was used on both occasions. Comparing the two periods, there were no significant differences regarding cumulative wheezing, active asthma, four or more wheezing attacks within the last year, sleep disturbed by wheezing more than one night per week, and speech-limiting wheezing. The prevalences of exercise-induced wheezing, dry cough at night, and physician-diagnosed asthma were significantly higher in 2010 than in the 2006-2007 period (p school students than in public school students (p school students.

Physical and emotional violence against adolescents is a neglected, but growing problem globally. Violence against adolescents negatively affects the victim in terms of physical health, school attendance and performance and social adjustment. The literature on the prevalence and associated factors of bullying against adolescents is sparse in southern Africa outside South Africa. Such data are even sparser for Malawi. The current study was conducted to estimate the prevalence of self-reported bullying and its personal and social correlates. A secondary analysis of the Malawi School-Based Student Health Survey (2009) was done. Descriptive analyses were done to describe the sample and estimate the prevalence of reporting history of bullying in the past 30 days preceding the survey. Logistic regression analysis was done to assess the association between several factors and being a victim of bullying. Crude and adjusted odds ratios are reported. A total of 2,264 in-school adolescents participated in the Malawi School-Based Student Health Survey of 2009. Just under half (44.5%) reported having been bullied in the previous month to the survey (44.1% among boys versus 44.9% among girls). Compared to adolescents of age 16 years or older, those who were 12 years old or younger and those who were 14 years of age were more likely to be bullied (AOR=1.54; 95% CI [1.41, 1.76]) and OR=1.26; 95% CI [1.21, 1.31]) respectively. The other risk factors that were identified in the analysis were loneliness (AOR = 2.23; 95% CI [2.20, 2.27]), and being worried (AOR = 2.80; 95% CI [2.76, 2.85[). Adolescents who had no close friends were 14% (AOR = 1.14; 95% CI [1.11-1.17]) more likely to be reporting bullied compared to adolescents who reported having close friends. Adolescents who smoked cigarettes were more than three times more likely to reporting be bullied compared to non-smokers (AOR=3.97; 955 CI [3.83, 4.10]), while those who drank alcohol were more than twice as likely to be

Two common ways of measuring disease prevalence include: (1) using self-reported disease diagnosis from survey responses; and (2) using disease-specific diagnosis codes found in administrative data. Because they do not suffer from self-report biases, claims are often assumed to be more objective. However, it is not clear that claims always produce better prevalence estimates. Conduct an assessment of discrepancies between self-report and claims-based measures for 2 diseases in the US elderly to investigate definition, selection, and measurement error issues which may help explain divergence between claims and self-report estimates of prevalence. Self-reported data from 3 sources are included: the Health and Retirement Study, the Medicare Current Beneficiary Survey, and the National Health and Nutrition Examination Survey. Claims-based disease measurements are provided from Medicare claims linked to Health and Retirement Study and Medicare Current Beneficiary Survey participants, comprehensive claims data from a 20% random sample of Medicare enrollees, and private health insurance claims from Humana Inc. Prevalence of diagnosed disease in the US elderly are computed and compared across sources. Two medical conditions are considered: diabetes and heart attack. Comparisons of diagnosed diabetes and heart attack prevalence show similar trends by source, but claims differ from self-reports with regard to levels. Selection into insurance plans, disease definitions, and the reference period used by algorithms are identified as sources contributing to differences. Claims and self-reports both have strengths and weaknesses, which researchers need to consider when interpreting estimates of prevalence from these 2 sources.

Multiple studies have found an increased prevalence, younger age at onset, and more severe course of glaucoma in people of African descent, but these findings are based on studies conducted outside Africa. To determine the prevalence of glaucoma in an urban West African population of adults. A population-based, cross-sectional study of adults 40 years and older conducted from September 1, 2006, through December 31, 2008, from 5 communities in Tema, Ghana. Participants from randomly selected clusters underwent a screening examination that consisted of visual acuity, frequency doubling perimetry, applanation tonometry, and optic disc photography. Participants who failed any of these tests were referred for complete examination, including gonioscopy, standard automated perimetry, and stereoscopic optic disc photography. A total of 6806 eligible participants were identified, and 5603 (82.3%) were enrolled in the study. The field examination referred 1869 participants (33.3%) to the clinic examination, and 1538 (82.2%) came for complete examination. A total of 362 participants were identified as having glaucoma of any type and category. Primary open-angle glaucoma was the underlying diagnosis in 342 participants (94.5%). The prevalence of primary open-angle glaucoma was 6.8% overall, increasing from 3.7% among those 40 to 49 years old to 14.6% among those 80 years and older, and was higher in men than in women in all age groups, with an overall male-female prevalence ratio of 1.5. Of the participants with glaucoma, 9 (2.5%) were blind using World Health Organization criteria, and only 12 (3.3%) were aware that they had glaucoma. The prevalence of glaucoma is higher in this urban West African population than in previous studies of people of East or South African and of non-African descent. Strategies to identify affected persons and effectively manage the burden of glaucoma are needed in West Africa.

The information on the changes of prevalence of MetS in China is limited. Our objective was to assess a 10-year's change of the prevalence of MetS in a Chinese elderly population between 2001 and 2010. We conducted two cross-sectional surveys in a representative sample of elderly population aged 60 to 95 years in Beijing in 2001 and 2010 respectively. MetS was defined according to the 2009 harmonizing definition. A total of 2,334 participants (943 male, 1,391 female) in 2001 and 2,102 participants (848 male, 1,254 female) in 2010 completed the survey. The prevalence of MetS was 50.4% (95%CI: 48.4%-52.4%) in 2001 and 58.1% (95%CI: 56.0%-60.2%) in 2010. The absolute change of prevalence of MetS was 7.7% over the 10-year's period (pdislipidemia.

Tobacco smoking surveillance: is quota sampling an efficient tool for monitoring national trends? A comparison with a random cross-sectional survey.

Directory of Open Access Journals (Sweden)

Full Text Available OBJECTIVES: It is crucial for policy makers to monitor the evolution of tobacco smoking prevalence. In France, this monitoring is based on a series of cross-sectional general population surveys, the Health Barometers, conducted every five years and based on random samples. A methodological study has been carried out to assess the reliability of a monitoring system based on regular quota sampling surveys for smoking prevalence. DESIGN / OUTCOME MEASURES: In 2010, current and daily tobacco smoking prevalences obtained in a quota survey on 8,018 people were compared with those of the 2010 Health Barometer carried out on 27,653 people. Prevalences were assessed separately according to the telephone equipment of the interviewee (landline phone owner vs "mobile-only", and logistic regressions were conducted in the pooled database to assess the impact of the telephone equipment and of the survey mode on the prevalences found. Finally, logistic regressions adjusted for sociodemographic characteristics were conducted in the random sample in order to determine the impact of the needed number of calls to interwiew "hard-to-reach" people on the prevalence found. RESULTS: Current and daily prevalences were higher in the random sample (respectively 33.9% and 27.5% in 15-75 years-old than in the quota sample (respectively 30.2% and 25.3%. In both surveys, current and daily prevalences were lower among landline phone owners (respectively 31.8% and 25.5% in the random sample and 28.9% and 24.0% in the quota survey. The required number of calls was slightly related to the smoking status after adjustment for sociodemographic characteristics. CONCLUSION: Random sampling appears to be more effective than quota sampling, mainly by making it possible to interview hard-to-reach populations.

To measure trends in the pulmonary tuberculosis burden between 2002 and 2011 and to assess the impact of the DOTS (directly observed treatment, short-course) strategy in Cambodia. Cambodia's first population-based nationwide tuberculosis survey, based on multistage cluster sampling, was conducted in 2002. The second tuberculosis survey, encompassing 62 clusters, followed in 2011. Participants aged 15 years or older were screened for active pulmonary tuberculosis with chest radiography and/or for tuberculosis symptoms. For diagnostic confirmation, sputum smear and culture were conducted on those whose screening results were positive. Of the 40,423 eligible subjects, 37,417 (92.6%) participated in the survey; 103 smear-positive cases and 211 smear-negative, culture-positive cases were identified. The weighted prevalences of smear-positive tuberculosis and bacteriologically-positive tuberculosis were 271 (95% confidence interval, CI: 212-348) and 831 (95% CI: 707-977) per 100,000 population, respectively. Tuberculosis prevalence was higher in men than women and increased with age. A 38% decline in smear-positive tuberculosis (P = 0.0085) was observed with respect to the 2002 survey, after participants were matched by demographic and geographical characteristics. The prevalence of symptomatic, smear-positive tuberculosis decreased by 56% (P = 0.001), whereas the prevalence of asymptomatic, smear-positive tuberculosis decreased by only 7% (P = 0.7249). The tuberculosis burden in Cambodia has declined significantly, most probably because of the decentralization of DOTS to health centres. To further reduce the tuberculosis burden in Cambodia, tuberculosis control should be strengthened and should focus on identifying cases without symptoms and in the middle-aged and elderly population.

This paper reviews and discusses the main procedures and policies that need to be followed when designing and implementing a binational survey such as the United States of America (U.S.)-Mexico Border Diabetes Prevalence Study that took place between 2001 and 2002. The main objective of the survey was to determine the prevalence of diabetes in the population 18 years of age or older along U.S.-Mexico border counties and municipalities. Several political, administrative, financial, legal, and cultural issues were identified as critical factors that need to be considered when developing and implementing similar binational projects. The lack of understanding of public health practices, implementation of existing policies, legislation, and management procedures in Mexico and the United States may delay or cancel binational research, affecting the working relation of both countries. Many challenges were identified: multiagency/multifunding, ethical/budget clearances, project management, administrative procedures, laboratory procedures, cultural issues, and project communications. Binational projects are complex; they require coordination between agencies and institutions at federal, state, and local levels and between countries and need a political, administrative, bureaucratic, cultural, and language balance. Binational agencies and staff should coordinate these projects for successful implementation.

In population surveys, up to 30% of participants reported chronic pain. Reports of chronic pain do not necessarily imply disability associated with pain. We assessed the prevalence of chronic disabling noncancer pain and associated demographic and medical variables in a sample of the general German population. A cross-sectional survey was conducted with 4360 people aged 14 years and above, who were representative of the German population. Measures were obtained for demographic variables, presence of chronic pain (based on the definition of the International Association for the Study of Pain), chronic pain stages (based on a chronic pain grade questionnaire), and disease load (based on the self-reported comorbidity questionnaire). Responses were received from 2508 people. The prevalence of chronic pain was 28.3% (95% [confidence interval] CI, 26.5%-30.1%). In all, 7.3% (95% CI, 5.9%-8.7%) of participants met the criteria of chronic disabling noncancer pain. Chronic disabling noncancer pain was associated with age above 65 years (odds ratios [OR]=4.81 [95% CI, 1.57-14.79]), low family income (OR=2.54 [95% CI, 1.36-4.74]), obesity (OR=3.58 [95% CI, 2.21-5.79]), heart disease (OR=2.23 [95% CI, 3.69-11.40]), stomach disease (OR=4.24 [95% CI, 2.12-8.49]), and rheumatic disease (OR=3.67 [95% CI, 2.16-6.23]) when compared with no chronic pain. Chronic disabling noncancer pain was associated with low family income (OR=2.29 [95% CI, 1.23-4.27]), obesity (OR=2.14 [95% CI, 1.30-3.52]), and depression (OR=3.26 [95% CI, 1.90-5.66]) when compared with chronic nondisabling noncancer pain. Prevalence rates of chronic disabling pain in the general population rather than prevalence rates of chronic pain might provide evidence in support of pain specialist care. The association of chronic disabling noncancer pain with mental disorders highlights the need for psychosocial services in chronic pain management.

The employment of professional interviewers from academic survey centers to conduct surveys has been standard practice. Because one goal of community-engaged research is to provide professional skills to community residents, this paper considers whether employing locally trained lay interviewers from within the community may be as effective as employing interviewers from an academic survey center with regard to unit and item nonresponse rates and cost. To study a nutrition-focused intervention, 1035 in-person household interviews were conducted in East Los Angeles and Boyle Heights, 503 of which were completed by lay community interviewers. A chi-square test was used to assess differences in unit nonresponse rates between professional and community interviewers and Welch's t tests were used to assess differences in item nonresponse rates. A cost comparison analysis between the two interviewer groups was also conducted. Interviewers from the academic survey center had lower unit nonresponse rates than the lay community interviewers (16.2% vs. 23.3%; p < 0.01). However, the item nonresponse rates were lower for the community interviewers than the professional interviewers (1.4% vs. 3.3%; p < 0.01). Community interviewers cost approximately $415.38 per survey whereas professional interviewers cost approximately $537.29 per survey. With a lower cost per completed survey and lower item nonresponse rates, lay community interviewers are a viable alternative to professional interviewers for fieldwork in community-based research. Additional research is needed to assess other important aspects of data quality interviewer such as interviewer effects and response error.

Objectives Population-based HIV testing surveys have become central to deriving estimates of national HIV prevalence in sub-Saharan Africa. However, limited participation in these surveys can lead to selection bias. We control for selection bias in national HIV prevalence estimates using a novel approach, which unlike conventional imputation can account for selection on unobserved factors. Methods For 12 Demographic and Health Surveys conducted from 2001 to 2009 (N=138 300), we predict HIV status among those missing a valid HIV test with Heckman-type selection models, which allow for correlation between infection status and participation in survey HIV testing. We compare these estimates with conventional ones and introduce a simulation procedure that incorporates regression model parameter uncertainty into confidence intervals. Results Selection model point estimates of national HIV prevalence were greater than unadjusted estimates for 10 of 12 surveys for men and 11 of 12 surveys for women, and were also greater than the majority of estimates obtained from conventional imputation, with significantly higher HIV prevalence estimates for men in Cote d'Ivoire 2005, Mali 2006 and Zambia 2007. Accounting for selective non-participation yielded 95% confidence intervals around HIV prevalence estimates that are wider than those obtained with conventional imputation by an average factor of 4.5. Conclusions Our analysis indicates that national HIV prevalence estimates for many countries in sub-Saharan African are more uncertain than previously thought, and may be underestimated in several cases, underscoring the need for increasing participation in HIV surveys. Heckman-type selection models should be included in the set of tools used for routine estimation of HIV prevalence. PMID:23172342

Full Text Available BACKGROUND: Integrated biobehavioral surveys (IBBS have been used to evaluate the impact of HIV prevention efforts among most-at-risk groups in Ukraine since 2007. Harm reduction program coverage among injecting-drug users (IDUs increased substantially from 96,000 in 2008 to 170,000 in 2010 with support from the Global Fund, and IBBS have shown declining HIV prevalence. Aim of the study was to examine the changes in HIV prevalence, drug use patterns and risky behaviors in IDUs on national and city level.METHODS: For this analysis, three IDU-IBBS datasets were combined – 2008 (N=3711, 2009 (N=3962, and 2011 (N=9069. The analysis included 25 cities that participated in either 2008 or 2009, and 2011. Changes in HIV prevalence, drug use, and risk behaviors were compared between 2008/9 and 2011.RESULTS: The surveyed IDU population in 2011 was older than in 2008/9 (31.0 vs. 32.8 years; p<.0001, and included more females (23.5% vs. 25.5%; p=.0038, with substantial variation across cities.Overall HIV prevalence in the sample declined slightly (22.9% to 21.6%; p=.05. In eight cities, HIV prevalence decreased significantly (-5% to -18%, while significant increases were seen in five cities (8% to 15%. Prevalence among IDUs younger than 25 years declined (9.9% to 7.2%; p=.0078.The combined dataset showed no difference in opioid or stimulant past-30-day use, with variation at city level. Clean needle/syringe use during last injection increased significantly (88.8% to 97.0%; p<.0001, with no opposing trend in any city. Three cities had an increase in past-30-day needle/syringe sharing; nine – in container sharing; twelve – in use of preloaded syringes. Changes in condom use were not significant (54.1% to 54.9%, p=.32.CONCLUSIONS: IDUs in Ukraine are ageing and HIV seroprevalence among IDUs continues to decline, especially among young IDUs. However, prevention programming needs to respond to significant regional variations in risk behaviors and HIV

Women have a higher prevalence of major depressive episodes (MDE) than men, and the annual prevalence of MDE declines with age. Age by sex interactions may occur (a weakening of the sex effect with age), but are easily overlooked since individual studies lack statistical power to detect interactions. The objective of this study was to evaluate age by sex interactions in MDE prevalence. In Canada, a series of 10 national surveys conducted between 1996 and 2013 assessed MDE prevalence in respondents over the age of 14. Treating age as a continuous variable, binomial and linear regression was used to model age by sex interactions in each survey. To increase power, the survey-specific interaction coefficients were then pooled using meta-analytic methods. The estimated interaction terms were homogeneous. In the binomial regression model I (2) was 31.2 % and was not statistically significant (Q statistic = 13.1, df = 9, p = 0.159). The pooled estimate (-0.004) was significant (z = 3.13, p = 0.002), indicating that the effect of sex became weaker with increasing age. This resulted in near disappearance of the sex difference in the 75+ age group. This finding was also supported by an examination of age- and sex-specific estimates pooled across the surveys. The association of MDE prevalence with sex becomes weaker with age. The interaction may reflect biological effect modification. Investigators should test for, and consider inclusion of age by sex interactions in epidemiological analyses of MDE prevalence.

Study Objectives: Sleep bruxism (SB) is characterized by tooth grinding and jaw clenching during sleep. Familial factors may contribute to the occurrence of SB. This study aims are: (1) revisit the prevalence and characteristics of SB in a large cross-sectional survey and assess familial aggregation of SB, (2) assess comorbidity such as insomnia and pain, (3) compare survey data in a subset of subjects diagnosed using polysomnography research criteria. Methods: A sample of 6,357 individuals from the general population in Quebec, Canada, undertook an online survey to assess the prevalence of SB, comorbidities, and familial aggregation. Data on familial aggregation were compared to 111 SB subjects diagnosed using polysomnography. Results: Regularly occurring SB was reported by 8.6% of the general population, decreases with age, without any gender difference. SB awareness is concomitant with complaints of difficulties maintaining sleep in 47.6% of the cases. A third of SB positive probands reported pain. A 2.5 risk ratio of having a first-degree family member with SB was found in SB positive probands. The risk of reporting SB in first-degree family ranges from 1.4 to 2.9 with increasing severity of reported SB. Polysomnographic data shows that 37% of SB subjects had at least one first-degree relative with reported SB with a relative risk ratio of 4.625.

The annual risk of tuberculosis infection (ARTI) data in Saudi Arabia has not been updated since 1993. To estimate the prevalence of latent TB infection (LTBI) and ARTI in a population-based sample in Saudi Arabia using Tuberculin skin test (TST) and QuantiFERON TB Gold in tube (QFT-GIT) test. A population-based cross sectional study was conducted between July 2010 and March 2013. Participants were randomly selected from the population served by the primary healthcare centers of the Ministry of National Guard Health Affairs in Riyadh, Jeddah, Alhassa and Dammam, Saudi Arabia. A total of 1369 participants were included. The overall prevalence of LTBI was similar using TST and QFT-GIT (9.3% and 9.1% respectively, p=0.872) but stratified prevalence rates were variable in all sociodemographic groups except marital status. Additionally, the prevalence rates of LTBI using either test alone showed significant differences by several sociodemographic and behavioral characteristics. The overall ARTI was 0.36% using TST and 0.35% using QFT-GIT. We are reporting much lower estimates for the prevalence of LTBI and the ARTI in a population-based sample in Saudi Arabia relative to the data that have been used for more than two decades.

Hyperpalatable foods (i.e., high in salt, sugar, or fat) have been shown to have addictive properties that may contribute to overeating. Prior studies conducted on food addiction behaviors are mostly based on white and middle-aged women. Data are not available, however, on reproductive-aged women from other races/ethnicities or low-income women. The purpose of this study was to examine the prevalence and correlates of food addiction among multiethnic women of low socioeconomic status. We conducted a cross-sectional survey of health behaviors, including food addiction according to the Yale Food Addiction Scale (YFAS) between July 2010 and February 2011 among 18- to 40-year-old low-income women attending reproductive-health clinics (N = 1,067). Overall, 2.8% of women surveyed met the diagnosis of food addiction. The prevalence of food addiction did not differ by age group, race/ethnicity, education, income, or body mass index categories, tobacco and alcohol use, or physical activity. However, it did differ by level of depression (p addiction among low-income, reproductive-aged women. Racial differences were observed in the YFAS symptom count score, but not in the overall prevalence of food addition. Additionally, women with food addiction had higher levels of depression than women without food addiction.

Full Text Available Abstract Background As biobanks play an increasing role in the genomic research that will lead to precision medicine, input from diverse and large populations of patients in a variety of health care settings will be important in order to successfully carry out such studies. One important topic is participants’ views towards consent and data sharing, especially since the 2011 Advanced Notice of Proposed Rulemaking (ANPRM, and subsequently the 2015 Notice of Proposed Rulemaking (NPRM were issued by the Department of Health and Human Services (HHS and Office of Science and Technology Policy (OSTP. These notices required that participants consent to research uses of their de-identified tissue samples and most clinical data, and allowing such consent be obtained in a one-time, open-ended or “broad” fashion. Conducting a survey across multiple sites provides clear advantages to either a single site survey or using a large online database, and is a potentially powerful way of understanding the views of diverse populations on this topic. Methods A workgroup of the Electronic Medical Records and Genomics (eMERGE Network, a national consortium of 9 sites (13 separate institutions, 11 clinical centers supported by the National Human Genome Research Institute (NHGRI that combines DNA biorepositories with electronic medical record (EMR systems for large-scale genetic research, conducted a survey to understand patients’ views on consent, sample and data sharing for future research, biobank governance, data protection, and return of research results. Results Working across 9 sites to design and conduct a national survey presented challenges in organization, meeting human subjects guidelines at each institution, and survey development and implementation. The challenges were met through a committee structure to address each aspect of the project with representatives from all sites. Each committee’s output was integrated into the overall survey plan.

The aim of the current study was to estimate the prevalence and time trend of invalidating musculoskeletal pain in the Spanish population and its association with socio-demographic factors, lifestyle habits, self-reported health status, and comorbidity with other diseases analyzing data from 1993-2006 Spanish National Health Surveys (SNHS). We analyzed individualized data taken from the SNHS conducted in 1993 (n = 20,707), 2001 (n = 21,058), 2003 (n = 21,650) and 2006 (n = 29,478). Invalidating musculoskeletal pain was defined as pain suffered from the preceding 2 weeks that decreased main working activity or free-time activity by at least half a day. We analyzed socio-demographic characteristics, self-perceived health status, lifestyle habits, and comorbid conditions using multivariate logistic regression models. Overall, the prevalence of invalidating musculoskeletal pain in Spanish adults was 6.1% (95% CI, 5.7-6.4) in 1993, 7.3% (95% CI, 6.9-7.7) in 2001, 5.5% (95% CI, 5.1-5.9) in 2003 and 6.4% (95% CI 6-6.8) in 2006. The prevalence of invalidating musculoskeletal pain among women was almost twice that of men in every year (P postural hygiene, physical exercise, and how to prevent obesity and sedentary lifestyle habits should be provided by Public Health Services. This population-based study indicates that invalidating musculoskeletal pain that reduces main working activity is a public health problem in Spain. The prevalence of invalidating musculoskeletal pain was higher in women than in men and associated to lower income, poor sleeping, worse self-reported health status, and other comorbid conditions. Further, the prevalence of invalidating musculoskeletal pain increased from 1993 to 2001, but remained stable from the last years (2001 to 2006).

Full Text Available Abstract Background Sentinel surveillance for HIV in ante-natal clinics (ANC remains the primary method for collecting timely trend data on HIV prevalence in most of sub-Saharan Africa. We describe prevalence of HIV and syphilis infection and trends over time in HIV prevalence among women attending ante-natal clinics (ANC in Magu district and Mwanza city, part of Mwanza region in Northern Tanzania. HIV prevalence from ANC surveys in 2000 and 2002 was 10.5% and 10.8% respectively. In previous rounds urban residence, residential mobility, the length of time sexually active before marriage, time since marriage and age of the partner were associated with HIV infection. Methods A third round of HIV sentinel surveillance was conducted at ante-natal clinics in Mwanza region, Tanzania during 2006. We interviewed women attending 27 ante-natal clinics. In 15 clinics we also anonymously tested women for syphilis and HIV infection and linked these results to the questionnaire data. Results HIV prevalence was 7.6% overall in 2006 and 7.4% at the 11 clinics used in previous rounds. Geographical variations in HIV prevalence, apparent in previous rounds, have largely disappeared but syphilis prevalence is still higher in rural clinics. HIV prevalence has declined in urban clinics and is stable in rural clinics. The correlates of HIV infection have changed over time. In this round older age, lower gravidity, remarriage, duration of marriage, sexual activity before marriage, long interval between last birth and pregnancy and child death were all associated with infection. Conclusions HIV prevalence trends concur with results from a community-based cohort in the region. Correlates of HIV infection have also changed and more proximate, individual level factors are now more important, in line with the changing epidemiology of infection in this population.

Human immunodeficiency virus (HIV) prevalence is often high among female sex workers (FSWs) in sub-Saharan Africa. Understanding the dynamics of HIV infection in this key population is critical to developing appropriate prevention strategies. We aimed to describe the prevalence and associated risk factors among a sample of FSWs in Rwanda from a survey conducted in 2010. A cross-sectional biological and behavioral survey was conducted among FSWs in Rwanda. Time-location sampling was used for participant recruitment from 4 to 18 February 2010. HIV testing was done using HIV rapid diagnostic tests (RDT) as per Rwandan national guidelines at the time of the survey. Elisa tests were simultaneously done on all samples tested HIV-positive on RDT. Proportions were used for sample description; multivariable logistic regression model was performed to analyze factors associated with HIV infection. Of 1338 women included in the study, 1112 consented to HIV testing, and the overall HIV prevalence was 51.0%. Sixty percent had been engaged in sex work for less than five years and 80% were street based. In multivariable logistic regression, HIV prevalence was higher in FSWs 25 years or older (adjusted odds ratio [aOR] = 1.83, 95% [confidence interval (CI): 1.42-2.37]), FSWs with consistent condom use in the last 30 days (aOR = 1.39, [95% CI: 1.05-1.82]), and FSWs experiencing at least one STI symptom in the last 12 months (aOR = 1.74 [95% CI: 1.34-2.26]). There was an inverse relationship between HIV prevalence and comprehensive HIV knowledge (aOR = 0.65, [95% CI: 0.48-0.88]). HIV prevalence was high among a sample of FSWs in Rwanda, and successful prevention strategies should focus on HIV education, treatment of sexually transmitted infections, and proper and consistent condom use using an outreach approach.

Epidemiological studies of lower urinary tract symptoms (LUTS) are few in China, and none has been conducted nationwide. To estimate the prevalence and potential risk factors of LUTS and the bother they impose on adult women in China. This is the second analysis of a population-based cross-sectional survey on urinary incontinence conducted between February and July 2006 in six regions of China. Cluster samples were randomly selected for interviews. No intervention was implemented. A modified Chinese Bristol Female Lower Urinary Tract Symptoms questionnaire was administered. The participants were asked about the presence of individual LUTS and rated their symptom bother. Descriptive statistics, χ(2) tests, receiver operating characteristic curves, and multivariate logistic regressions were used for data analysis. A total of 18 992 respondents (94.96%) were included. The prevalence of any LUTS, storage symptoms, or voiding symptoms was 55.5%, 53.9%, and 12.9%, respectively, and increased with age. Nocturia was the most common symptom (23.4%), followed by urgency (23.3%) and stress urinary incontinence (SUI; 18.9%). Nocturia was most frequently rated as bothersome (93.0%) but was generally minor (80.5%). Urgency and urgency urinary incontinence (UUI) were most frequently reported as severe (11.5% and 10.8%) or moderate (18.5% and 16.8%) bothers. Any LUTS were more prevalent in urban women (57.1% vs 53.9%). Multiple factors increased the odds of bother and individual LUTS, and older age and coexisting pelvic organ prolapse were strong predictors (pfactors influenced bother and individual LUTS. The prevalence of lower urinary tract symptoms is high and increases with age in adult women in China. Urgency and urgency urinary incontinence were most frequently regarded as severe or moderate bothers and should be targeted for medical intervention. Copyright © 2014 European Association of Urology.

2017-01-01

Full Text Available This paper aims to present results of the survey on sexual harassment of students of the Faculty of Special Education and Rehabilitation, University of Belgrade. It starts with presenting and discussing different definitions of the term ‘sexual harassment’. Afterwards, a brief overview of available surveys on this subject is provided. Results of the surveys completed so far show that this kind of students’ victimization in educational institutions is frequent in all parts of the world, regardless of the economic, ethnic and religious grounds. The aim of the survey conducted at the Faculty of Special Education and Rehabilitation (FASPER was to identify the prevalence and characteristics of sexual harassment among undergraduate students, as well as possible forms of assistance and support to students who experience sexual harassment. A survey was conducted by the students of FASPER during April and May 2014 on a sample of 147 students of all four years of undergraduate studies. For data collection a victimization survey was used. The survey results suggested that sexual harassment of students of FASPER is prevalent, while it only manifests itself in a form of verbal harassment with a sexual connotation. Female students are more exposed to harassment than male students, but we need to interpret this finding with a caution due to the fact that a sample was mostly consisted of female respondents. According to the students’ opinion, possible solutions for preventing and eliminating sexual harassment of students of FASPER are education of students and employees, adoption of rules for protection of students from this kind of victimization and establishment of support service for students who experience victimization by sexual harassment.

Full Text Available Abstract Background Ghana has not conducted a national tuberculin survey or tuberculosis prevalence survey since the establishment of the National Tuberculosis Control Programme. The primary objective of this study was therefore to determine the prevalence of tuberculin skin sensitivity in Ghanaian school children aged 6-10 years in 8 out of 10 regions of Ghana between 2004 and 2006. Methods Tuberculin survey was conducted in 179 primary schools from 21 districts in 8 regions. Schools were purposively selected so as to reflect the proportion of affluent private and free tuition public schools as well as the proportion of small and large schools. Results Of the 24,778 children registered for the survey, 23,600 (95.2% were tested of which 21,861 (92.6% were available for reading. The age distribution showed an increase in numbers of children towards older age: 11% of the children were 6 years and 25%, 10 years. Females were 52.5% and males 47.5%. The proportion of girls was higher in all age groups (range 51.4% to 54.0%, p Conclusion Tuberculosis infection is still a public health problem in Ghana and to monitor the trend, the survey needs to be repeated at 5 years interval.

Neuroinfectious diseases in livestock represent a severe threat to animal health, but their prevalence is not well documented and the etiology of disease often remains unidentified. The aims of this study were to generate baseline data on the prevalence of neuroinfectious diseases in cattle in Switzerland by neuropathological survey, and to identify disease-associated pathogens. The survey was performed over a 1-year period using a representative number of brainstem samples (n=1816) from fallen cattle. In total, 4% (n=73) of the animals had significant lesions, the most frequent types of which were indicative of viral (n=27) and bacterial (n=31) etiologies. Follow-up diagnostics by immunohistochemistry, PCR protocols and next-generation sequencing identified infection with Listeria monocytogenes (n=6), ovine herpesvirus 2 (n=7), bovine astrovirus CH13 (n=2), bovine herpesvirus 6 (n=6), bovine retrovirus CH15 (n=2), posavirus 1 (n=2), and porcine astroviruses (n=2). A retrospective questionnaire-based investigation indicated that animals' owners observed clinical signs of neurological disease in about one-third of cases with lesions, which was estimated to correspond to approximately 85 cases per year in the adult fallen cattle population in Switzerland. This estimate stands in sharp contrast to the number of cases reported to the authorities and reveals a gap in disease surveillance. Systematic neuropathological examination and follow-up molecular testing of neurologically diseased cattle could significantly enhance the efficiency of disease detection for the purposes of estimating the prevalence of endemic diseases, identifying new or re-emerging pathogens, and providing "early warnings" of disease outbreaks.

Full Text Available Asthma remains poorly studied in homeless children. We sought to estimate the prevalence of asthma-like symptoms (ALS and to identify the factors associated with ALS and healthcare service utilisation.A cross-sectional survey of a random sample of sheltered homeless families was conducted by interviewing 801 parents of children (0-12 years in 17 languages. ALS were defined as wheezing or night cough without fever during the previous year. Poisson regression models with robust error variance were used to compute prevalence ratios (PR for factors associated with ALS and healthcare service utilisation for ALS.The prevalence of ALS among the children was 19.9%. Poor housing sanitation was significantly associated with ALS, as being born in the European Union. Most of the children with ALS had used healthcare services (85.4%. The main barriers to accessing such services were having lived in France for less than 49 months, having difficulties in French and living in poor housing conditions.ALS prevalence seemed lower than in the general child population, possibly because of the children's origins. Environmental factors associated with ALS point to the need to improve the indoor environment of family shelters. The relatively high rate of healthcare service utilisation should not overshadow existing barriers.

2017-01-01

Background No nationwide epidemiological study evaluating the prevalence of subclinical and overt forms of hypothyroidism and hyperthyroidism has yet been conducted in Korea. This study aimed to evaluate the reference range of serum thyroid stimulating hormone (TSH) and the national prevalence of thyroid dysfunctions in Korea. Methods Nation-wide cross-sectional data were analyzed from a representative sample of the civilian, non-institutionalized Korean population (n=6,564) who underwent blood testing for thyroid function and anti-thyroid peroxidase antibody (TPOAb) as part of the Korea National Health and Nutrition Examination Survey VI (2013 to 2015). Results The reference interval of serum TSH in the Korean reference population was 0.62 to 6.68 mIU/L. Based on this reference interval, the prevalence of overt and subclinical hypothyroidism was 0.73% (males 0.40%, females 1.10%) and 3.10% (males 2.26%, females 4.04%), respectively. The prevalence of hypothyroidism increased with age until the age group between 50 to 59 years. Positive TPOAb were found in 7.30% of subjects (males 4.33%, females 10.62%). The prevalence of overt and subclinical hypothyroidism TPOAb-positive subjects was 5.16% and 10.88%, respectively. The prevalence of overt and subclinical hyperthyroidism was 0.54% (males 0.30%, females 0.81%) and 2.98% (males 2.43%, females, 3.59%), respectively. Conclusion The Serum TSH reference levels in the Korean population were higher than the corresponding levels in Western countries. Differences were found in the prevalence of hypothyroidism and hyperthyroidism according to age, sex, and TPOAb positivity. This study provides important baseline information for understanding patterns of thyroid dysfunction and diseases in Korea. PMID:28116874

Objective: To study the prevalence and pattern of self-medication among adult males and females in Karachi, Pakistan. Methods: This cross-sectional community- based survey was carried out at five randomly selected towns of Karachi (Defence, Gulshan-e-Iqbal, North Nazimabad, Malir, Orangi town) over a period of 3 months (October, November & December 2012). A sample size of 500 adult cases (250 males & 250 females), with systemic random selection from different towns of Karachi were inducted in this study. The city was divided in 5 zones and one town from each zone was selected by systemic randomization. First available male and female from each randomly selected house were included in the study. After consent and confidentiality assurance they were interviewed on semi-structured Performa designed for this purpose. Results were analyzed and tabulated through SPSS v14.0. Result: The prevalence of self-medication in males and females in Karachi is found to be 84.8% (males 88.4% and females 81.2%). The most frequent symptoms for which self-medication used were headache (32.7%), fever (23.3%) and the medicines used were painkillers (28.8%), fever reducer medicines (19.8%). The most common reason 33.3% was previous experience with similar symptom. Conclusion: Self-medication is highly prevalent (84.8%) in Karachi. It was frequently used for headache followed by fever. Predominantly painkillers, fever reducer and cough syrups were used in the form of tablets and syrups. Main source of medicines for males were friends and for females were relatives. PMID:26649022

Full Text Available The prevalence of diabetes, dyslipidemias, and high blood pressure is increasing worldwide especially in low and middle income countries. World Health Organization has emphasized the importance of the assessment of the magnitude of the specific disease in each country. We determined the prevalence and determinant factors of high blood pressure, hyperglycemia, dyslipidemias and metabolic syndrome in Ethiopia. A community based survey was conducted from -April to June 2015 using WHO NCD STEPS instrument version 3.1. 2008. Multistage stratified systemic random sampling was used to select representative samples from 9 regions of the country. A total of 10,260 people aged 15-69 years participated in the study. Blood pressure (BP was measured for 9788 individuals. A total of 9141 people underwent metabolic screening. The prevalence of raised blood pressure (SBP ≥140 and/or DBP ≥ 90 mmHg was 15.8% (16.3% in females and 15.5% in males. The prevalence of diabetes mellitus (FBS ≥ 126 mg /dl including those on medication was 3.2% (3.5% males and 3.0% females. The prevalence of impaired fasting glucose was 9.1% with ADA criteria and 3.8% with WHO criteria. Hypercholesterolemia was found in 5.2%, hypertriglyceridemia in 21.0%, high LDL cholesterol occurred in 14.1% and low HDL cholesterol occurred in 68.7%. The prevalence of metabolic syndrome using IDF definition was 4.8% (8.6% in females and vs. 1.8% in males. Advanced age, urban residence, lack of physical exercise, raised waist circumference, raised waist hip ratio, overweight or obesity, and total blood cholesterol were significantly associated with raised blood pressure (BP and diabetes mellitus. Increased waist- hip ratio was an independent predictor of raised blood pressure, hyperglycemia and raised total cholesterol. Our study showed significantly high prevalence of raised blood pressure, hyperglycemia and dyslipidemia in Ethiopia. Community based interventions are recommended to control these

Full Text Available BACKGROUND: Although crime victimisation is as prevalent in psychiatric patients as crime perpetration (and possibly more so, few European figures for it are available. We therefore assessed its one-year prevalence and incident rates in Dutch severely mentally ill outpatients, and compared the results with victimisation rates in the general population. METHOD: This multisite epidemiological survey included a random sample of 956 adult severely mentally ill outpatients. Data on victimisation were obtained using the victimisation scale of the Dutch Crime and Victimisation Survey, which assesses crime victimisation over the preceding 12 months. Comparison data were derived from the nationwide survey on safety and victimisation in the Netherlands. Prevalence and incident rates were weighted for sex, age, ethnicity and socioeconomic status, and compared with a general population sample matched by region (N = 38,227. RESULTS: In the past year, almost half of the severely mentally ill outpatients (47% had been victim of a crime. After control for demographic differences, prevalence rates of overall and specific victimisation measures were significantly higher in severely mentally ill outpatients than in the general population. The relative rates were especially high for personal crimes such as violent threats (RR = 2.12, 95% CI: 1.72-2.61, physical assaults (RR = 4.85, 95% CI: 3.69-6.39 and sexual harassment and assaults (RR = 3.94, 95% CI: 3.05-5.09. In concordance, severely mentally ill outpatients reported almost 14 times more personal crime incidents than persons from the general population (IRR = 13.68, 95% CI: 12.85-14.56. CONCLUSION: Crime victimisation is a serious problem in Dutch severely mentally ill outpatients. Mental-healthcare institutions and clinicians should become aware of their patients' victimisation risk, and should implement structural measures to detect and prevent (re-victimisation.

In 2007 and 2012, the Global School-Based Student Health Survey (GSHS) and the Global Youth Tobacco Survey (GYTS) were implemented to estimate the prevalence of risk behaviors and protection factors among 13 to 15 year-old adolescents. To assess changes in dietary, body weight, tobacco and physical activity indicators in the past five years. Cross-sectional study. A randomized, two-stage sampling with 600 schools selected at a national level was used. Students from randomly selected courses were invited to answer a self-administered questionnaire (either the GSHS or the GYTS). In 2012, the GSHS was completed by 20 697 students from 544 schools, while the GYTS was completed by 2062 students from 73 schools. Between 2007 and 2012, overweight and obesity prevalence significantly increased (overweight: 24.5% in 2007, 28.6% in 2012; obesity 4.4% in 2007, 5.9% in 2012), while the consumption of sugar-sweetened beverages and fast food remained high. A slight improvement was observed in the level of physical activity (12.7% in 2007, 16.7% in 2012), although it remains below what is recommended. The prevalence of tobacco use was reduced (24.5% in 2007, 19.6% in 2012), but access to tobacco products and exposure to secondhand smoke remains high in public places, including schools. The spread of the overweight and obesity epidemic calls for a need to consolidate actions tending towards a healthy diet and physical activity. Despite a decrease in the prevalence of tobacco use, it is necessary to continue strengthening tobacco control actions.

Objective The information on the changes of prevalence of MetS in China is limited. Our objective was to assess a 10-year’s change of the prevalence of MetS in a Chinese elderly population between 2001 and 2010. Methods We conducted two cross-sectional surveys in a representative sample of elderly population aged 60 to 95 years in Beijing in 2001 and 2010 respectively. MetS was defined according to the 2009 harmonizing definition. Results A total of 2,334 participants (943 male, 1,391 female) in 2001 and 2,102 participants (848 male, 1,254 female) in 2010 completed the survey. The prevalence of MetS was 50.4% (95%CI: 48.4%–52.4%) in 2001 and 58.1% (95%CI: 56.0%–60.2%) in 2010. The absolute change of prevalence of MetS was 7.7% over the 10-year’s period (pdislipidemia.

There are limited data on the epidemiology of paediatric healthcare-associated infection (HCAI) and infection control in low-income countries. We describe the value of intermittent point-prevalence surveys for monitoring HCAI and evaluating infection control interventions in a Cambodian paediatric hospital. Hospital-wide, point-prevalence surveys were performed monthly in 2011. Infection control interventions introduced during this period included a hand hygiene programme and a ventilator-associated pneumonia (VAP) care bundle. Overall HCAI prevalence was 13.8/100 patients at-risk, with a significant decline over time. The highest HCAI rates (50%) were observed in critical care; the majority of HCAIs were respiratory (61%). Klebsiella pneumoniae was most commonly isolated and antimicrobial resistance was widespread. Hand hygiene compliance doubled to 51.6%, and total VAP cases/1000 patient-ventilator days fell from 30 to 10. Rates of HCAI were substantial in our institution, and antimicrobial resistance a major concern. Point-prevalence surveys are effective for HCAI surveillance, and in monitoring trends in response to infection control interventions.

The aim of this study was to determine the prevalence of overweight and obese subjects in the Shanghai population of China and its association with undiagnosed hypertension, by taking age, gender and place of residence (urban or suburban) into account. A cross-sectional population-based survey was conducted in 2007. The sample included 13,359 participants aged 15-69 years.Weight, height, and blood pressure were recorded, and information about gender, age and place of residence was obtained. Overweight and obesity prevalence were calculated by the body mass index (BMI) definition recommended by Working Group on Obesity in China (normal weight, 18.5-23.9 kg/m(2); overweight, 24-27.9 kg/m(2); obesity, ≥ 28 kg/m(2)). Undiagnosed hypertension was defined by China criteria in accord with that of WHO-ISH (subjects with systolic pressure ≥ 140 mmHg, and/or diastolic pressure ≥ 90 mmHg). Multiple logistic regression analyses were used to assess the association of overweight or obesity with undiagnosed hypertension by adjusting for age, gender and place of residence. The overall overweight, obesity, and undiagnosed hypertension prevalence were 27.6% (95% CI: 26.8-28.4), 6.6% (95% CI: 6.2-7.0), and 15.5% (95% CI: 14.9-16.1), respectively. Compared to normal weight subjects, the odds ratios (OR) for subjects who were overweight and had hypertension was 2.33 (95% CI: 2.10-2.59); that for obesity and hypertension was 4.27 (95% CI: 3.66-4.99). These data suggest that overweight and obesity prevalence and their association with undiagnosed hypertension are high in our study population.

Although acne vulgaris is a common skin disorder, limited epidemiological data exist specifically for European populations. To determine the prevalence of self-reported acne among young people in Europe and evaluate the effect of lifestyle on acne. We conducted a cross-sectional population-based online survey in representative samples of individuals aged 15-24 years in Belgium, Czech and Slovak Republics, France, Italy, Poland and Spain (n = 10 521), identified by a quota sampling method based on age, geographic location and socio-professional category. The overall adjusted prevalence of self-reported acne was 57.8% (95% confidence interval 56.9% to 58.7%). The rates per country ranged from 42.2% in Poland to 73.5% in the Czech and Slovak Republics. The prevalence of acne was highest at age 15-17 years and decreased with age. On multivariate analysis, a history of maternal or paternal acne was associated with an increased probability of having acne (odds ratio 3.077, 95% CI 2.743 to 3.451, and 2.700, 95% CI 2.391 to 3.049, respectively; both P chocolate (OR 1.276, 95% CI 1.094 to 1.488, for quartile 4 vs. quartile 1). Increasing age (OR 0.728, 95% CI 0.639 to 0.830 for age 21-24 years vs. 15-17 years) and smoking tobacco (OR 0.705, 95% CI 0.616 to 0.807) were associated with a reduced probability of acne. The overall prevalence of self-reported acne was high in adolescents/young adults in the European countries investigated. Heredity was the main risk factor for developing acne. © 2017 European Academy of Dermatology and Venereology.

2018-01-01

Chronic widespread pain (CWP) is a significant burden in communities. Understanding the impact of population-dependent (e.g., age, gender) and contextual-dependent (e.g. survey method, region, inequality level) factors have on CWP prevalence may provide a foundation for population-based strategies to address CWP. Therefore, the purpose of this study was to estimate the global prevalence of CWP and evaluate the population and contextual factors associated with CWP. A systematic review of CWP prevalence studies (1990-2017) in the general population was undertaken. Meta-analyses were conducted to determine CWP prevalence, and study population data and contextual factors were evaluated using a meta-regression. Thirty-nine manuscripts met the inclusion criteria. Study CWP prevalence ranged from 1.4% to 24.0%, with CWP prevalence in men ranging from 0.8% to 15.3% and 1.7% to 22.1% in women. Estimated overall CWP prevalence was 9.6% (8.0-11.2%). Meta-regression analyses showed gender, United Nations country development status, and human development index (HDI) influenced CWP prevalence, while survey method, region, methodological and reporting quality, and inequality showed no significant effect on the CWP estimate. Globally CWP affects one in ten individuals within the general population, with women more likely to experience CWP than men. HDI was noted to be the socioeconomic factor related to CWP prevalence, with those in more developed countries having a lower CWP prevalence than those in less developed countries. Most CWP estimates were from developed countries, and CWP estimates from countries with a lower socioeconomic position is needed to further refine the global estimate of CWP. This systematic review and meta-analysis updates the current global CWP prevalence by examining the population-level (e.g. age, gender) and contextual (e.g. country development status; survey style; reporting and methodologic quality) factors associated with CWP prevalence.

The objective of this study was to evaluate the validity of self-reported smoking prevalence in Korean adolescents by using an improved gold standard by a combined method. Using a stratified sampling method, we selected 13 schools from among 397 high schools that participated in the 2015 Korean Youth Health Risk Behavior Web-Based Survey (KYRBS). A second survey (repeated self-reporting questionnaire and urinary cotinine test) was conducted on 1058 students who completed the KYRBS. The gold standard of current smoker was defined as those either self-reporting as a smoker in the second survey or having a urinary cotinine concentration ≥50 ng/mL. The current smoking prevalence in the first survey (KYRBS) was 7.9% (boys 16.5% and girls 1.8%), which was lower than the results based on gold standard (11.3% total, boys 21.9% and girls 3.7%). The sensitivity and specificity of self-reported smoking status was 62.5% and 99.0%, respectively. In particular, the sensitivity of girls (43.5%) was lower than that of boys (67.0%). The self-reported smoking prevalence in Korean adolescents was underestimated, particularly among girls. Careful attention should be paid to interpreting adolescents' smoking prevalence, and supplementary surveys or periodic validity tests need to be considered in Asian countries.

Severe social withdrawal behaviors among young people have been a subject of public and clinical concerns. This study aimed to explore the prevalence of social withdrawal behaviors among young people aged 12-29 years in Hong Kong. A cross-sectional telephone-based survey was conducted with 1,010 young individuals. Social withdrawal behaviors were measured with the proposed research diagnostic criteria for hikikomori and were categorized according to the (a) international proposed duration criterion (more than 6 months), (b) local proposed criterion (less than 6 months) and (c) with withdrawal behaviors but self-perceived as non-problematic. The correlates of social withdrawal among the three groups were examined using multinomial and ordinal logistic regression analyses. The prevalence rates of more than 6 months, less than 6 months and self-perceived non-problematic social withdrawal were 1.9%, 2.5% and 2.6%, respectively. In terms of the correlates, the internationally and locally defined socially withdrawn youths are similar, while the self-perceived non-problematic group is comparable to the comparison group. The study finds that the prevalence of severe social withdrawal in Hong Kong is comparable to that in Japan. Both groups with withdrawal behaviors for more or less than 6 months share similar characteristics and are related to other contemporary youth issues, for example, compensated dating and self-injury behavior. The self-perceived non-problematic group appears to be a distinct group and the withdrawal behaviors of its members may be discretionary. © The Author(s) 2014.

Full Text Available Abstract Background Country level comparisons of HIV prevalence among men having sex with men (MSM is challenging for a variety of reasons, including differences in the definition and measurement of the denominator group, recruitment strategies and the HIV detection methods. To assess their comparability, self-reported data on HIV diagnoses in a 2010 pan-European MSM internet survey (EMIS were compared with pre-existing estimates of HIV prevalence in MSM from a variety of European countries. Methods The first pan-European survey of MSM recruited more than 180,000 men from 38 countries across Europe and included questions on the year and result of last HIV test. HIV prevalence as measured in EMIS was compared with national estimates of HIV prevalence based on studies using biological measurements or modelling approaches to explore the degree of agreement between different methods. Existing estimates were taken from Dublin Declaration Monitoring Reports or UNAIDS country fact sheets, and were verified by contacting the nominated contact points for HIV surveillance in EU/EEA countries. Results The EMIS self-reported measurements of HIV prevalence were strongly correlated with existing estimates based on biological measurement and modelling studies using surveillance data (R2=0.70 resp. 0.72. In most countries HIV positive MSM appeared disproportionately likely to participate in EMIS, and prevalences as measured in EMIS are approximately twice the estimates based on existing estimates. Conclusions Comparison of diagnosed HIV prevalence as measured in EMIS with pre-existing estimates based on biological measurements using varied sampling frames (e.g. Respondent Driven Sampling, Time and Location Sampling demonstrates a high correlation and suggests similar selection biases from both types of studies. For comparison with modelled estimates the self-selection bias of the Internet survey with increased participation of men diagnosed with HIV has to be

Data on the prevalence of dyslipidemia in Brazil are scarce, with surveys available only for some towns. To evaluate the prevalence of the self-reported medical diagnosis of high cholesterol in the Brazilian adult population by use of the 2013 National Health Survey data. Descriptive study assessing the 2013 National Health Survey data, a household-based epidemiological survey with a nationally representative sample and self-reported information. The sample consisted of 60,202 individuals who reported a medical diagnosis of dyslipidemia. The point prevalence and 95% confidence interval (95%CI) for the medical diagnosis of high cholesterol/triglyceride by gender, age, race/ethnicity, geographic region and educational level were calculated. Adjusted odds ratio was calculated. Of the 60,202 participants, 14.3% (95%CI=13.7-14.8) never had their cholesterol or triglyceride levels tested, but a higher frequency of women, white individuals, elderly and those with higher educational level had their cholesterol levels tested within the last year. The prevalence of the medical diagnosis of high cholesterol was 12.5% (9.7% in men and 15.1% in women), and women had 60% higher probability of a diagnosis of high cholesterol than men. The frequency of the medical diagnosis of high cholesterol increased up to the age of 59 years, being higher in white individuals or those of Asian heritage, in those with higher educational level and in residents of the Southern and Southeastern regions. The importance of dyslipidemia awareness in the present Brazilian epidemiological context must be emphasized to guide actions to control and prevent coronary heart disease, the leading cause of death in Brazil and worldwide. A prevalência de hipercolesterolemia no Brasil não é conhecida para todo o país, havendo somente inquéritos em algumas cidades.

Many animal surveys to estimate populations or index trends include protocol prohibiting counts during rain but fail to address effects of rainfall preceding the count. Prior research on Pacific Coast band-tailed pigeons (Patagioenas fasciata monilis) documented declines in use of mineral sites during rainfall. We hypothesized that prior precipitation was associated with a short-term increase in use of mineral sites following rain. We conducted weekly counts of band-tailed pigeons at 19 Pacific Northwest mineral sites in 2001 and 20 sites in 2002. Results from regression analysis indicated higher counts ???2 days after rain (11.31??5.00% [x????SE]) compared to ???3 days. Individual index counts conducted ???2 days after rain were biased high, resulting in reduced ability to accurately estimate population trends. Models of band-tailed pigeon visitation rates throughout the summer showed increased mineral-site counts during both June and August migration periods, relative to the July breeding period. Our research supported previous studies recommending that mineral-site counts used to index the band-tailed pigeon population be conducted during July. We further recommend conducting counts >3 days after rain to avoid weather-related bias in index estimation. The design of other population sampling strategies that rely on annual counts should consider the influence of aberrant weather not only coincident with but also preceding surveys if weather patterns are thought to influence behavior or detection probability of target species.

National surveys in countries outside Europe have reported a high prevalence (11-13%) of chronic kidney disease (CKD). Studies in Europe have provided a variable prevalence likely due to differences in study design, including age and extent of geographic areas, equation used to evaluate estimated glomerular filtration rate (eGFR) and CKD stages examined. The 2008-12 National Health Examination Survey in Italy randomly extracted samples from the general population aged 35-79 years, stratified by age and gender, from the resident list of each Italian region (440 persons/1.5 million of residents). We estimated the prevalence of CKD by means of urinary albumin : creatinine ratio and eGFR (CKD-EPI equation-enzymatic assay of serum creatinine). Cardiovascular (CV) risk profile was also evaluated. Three thousand eight hundred and forty-eight men and 3704 women were examined. In the whole population, mean age was 57 ± 12 and 56 ± 12 years in men and women, respectively; hypertension was prevalent in men and women, respectively (56 and 43%) and the same held true for overweight (48 and 33%), obesity (26 and 27%), diabetes (14 and 9%) and smoking (21 and 18%), whereas CV disease was less frequent (9 and 6%). Overall, the prevalence of CKD (95% confidence interval) was 7.05% (6.48-7.65). Early stages constituted 59% of the CKD population [Stage G1-2 A2-3: 4.16% (3.71-4.61) and Stage G3-5: 2.89% (2.51-3.26)]. At multivariate regression analysis, age, obesity, hypertension, diabetes, CV disease and smoking were all independent correlates of CKD. CKD has a relatively lower prevalence in Italy, in particular for advanced stages, when compared with similar national surveys outside Europe. This occurs despite older age and unfavourable CV risk profile of the whole population. © The Author 2014. Published by Oxford University Press on behalf of ERA-EDTA. All rights reserved.

Point-prevalence surveys have been used to document antimicrobial use in hospitals for >20 years. However, published surveys are inconsistent with respect to population, indication, and the details of therapy that were included. We aimed to standardize a method for surveillance of antibacterial use in hospitals from different health care systems and to identify targets for quality improvement. We adapted a Web-based reporting system from STRAMA, the Swedish Strategic Programme against antibiotic resistance. One hospital from each of 20 countries took part in the survey, which was completed during 2 calendar weeks during 1 April 2006 through 31 May 2006. The survey included all inpatient beds for adults and children and identified all patients who were receiving systemic antibacterial treatments on the day of survey and all patients who had received antibacterial prophylaxis for surgery on the previous day. On the day of survey there were 11,571 inpatients in the 20 participating hospitals, of whom 30.1% were receiving antibacterial treatment (range, 19%-59%). The most common anatomic sites of infection for which antibacterials were prescribed were respiratory tract (24%); skin, bone, and joint (18%); intra-abdominal organs (16%); and urinary tract (11%). The following 3 quality indicators were identified: indication documented in case notes (64%), prophylaxis for surgery not continued for >24 h (60%), and therapy for community-acquired pneumonia not including third-generation cephalosporins or quinolones (78.5%). A Web-based method for a point-prevalence survey was successfully piloted in 20 hospitals across Europe and offers a standardized instrument that can identify targets for quality improvement.

Full Text Available Abstract Background Coronary artery disease (CAD is a leading cause of mortality, morbidity, and disability with high health care cost in Iran. It accounts for nearly 50 percent of all deaths per year. Yet little is known about CAD and CAD risk factors in the Iranian population. We aimed to assess the prevalence of different CAD risk factors in an Iranian population. Methods A descriptive cross sectional survey was conducted involving 3000 healthy adults at 18 years of age or above who were recruited with cluster random sampling. Demographic data and risk factors were determined by taking history, physical examination and laboratory tests. Results The average age was 36.23 ± 15.26. There was 1381 female (46% and 1619 male (54% out of which 6.3% were diabetic, 21.6% were smoker, and 15% had positive familial heart disease history. 61% had total cholesterol level > 200 mg/dL, 32% triglyceride > 200 mg/dl, 47.5% LDL-c > 130 mg/dl, 5.4% HDL-c 140 mmHg, 9.1% diastolic blood pressure > 90 mmHg and 87% of them were physically inactive. Conclusion Clinical and Para-clinical data indicated that Iranian adult population are of a high level of CAD risk factors, which may require urgent decision making to address national control measures regarding CAD.

To describe the prevalence of DSM-IV disorders and comorbidity in a large population-based sample of British children and adolescents. Using a one-phase design, 10,438 children were assessed using the Development and Well-Being Assessment (DAWBA), a structured interview with verbatim reports reviewed by clinicians so that information from parents, teachers, and children was combined in a manner that emulated the clinical process. The authors' analysis examined comorbidity and the influence of teacher reports. The overall prevalence of DSM-IV disorders was 9.5% (95% confidence interval 8.8-10.1%), but 2.1% of children were assigned "not otherwise specified" rather than operationalized diagnoses. After adjusting for the presence of a third disorder, there was no longer significant comorbidity between anxiety and conduct disorder or attention-deficit/hyperactivity disorder (ADHD), or between depression and oppositional defiant disorder. A comparison of the disorders in children with and without teacher reports suggested that the prevalence of conduct disorders and ADHD would be underestimated in the absence of teacher information. Roughly 1 in 10 children have at least one DSM-IV disorder, involving a level of distress or social impairment likely to warrant treatment. Comorbidity reported between some childhood diagnoses may be due to the association of both disorders with a third. Diagnoses of conduct disorder and ADHD may be missed if information is not sought from teachers about children's functioning in school.

The Trauma Center Organizational Culture Survey (TRACCS) instrument was developed to assess organizational culture of trauma centers enrolled in the American College of Surgeons Trauma Quality Program (ACS TQIP). The objective is to provide evidence on the psychometric properties of the factors of TRACCS and describe the current organizational culture of TQIP-enrolled trauma centers. A cross-sectional study was conducted by surveying a sampling of employees at 174 TQIP-enrolled trauma centers. Data collection was preceded by multistep survey development. Psychometric properties were assessed by an exploratory factor analysis (construct validity) and the item-total correlations and Cronbach alpha were calculated (internal reliability). Statistical outcomes of the survey responses were measured by descriptive statistics and mixed effect models. The response rate for trauma center participation in the study was 78.7% (n = 137). The factor analysis resulted in 16 items clustered into three factors as described: opportunity, pride, and diversity, trauma center leadership, and employee respect and recognition. TRACCS was found to be highly reliable with a Cronbach alpha of 0.90 in addition to the three factors (0.91, 0.90, and 0.85). Considerable variability of TRACCS overall and factor score among hospitals was measured, with the largest interhospital deviations among trauma center leadership. More than 80% of the variability in the responses occurred within rather than between hospitals. TRACCS was developed as a reliable tool for measuring trauma center organizational culture. Relationships between TQIP outcomes and measured organizational culture are under investigation. Trauma centers could apply TRACCS to better understand current organizational culture and how change tools can impact culture and subsequent patient and process outcomes.

To estimate the prevalence of angina pectoris in the Brazilian adult population with the use of the Rose questionnaire for angina in the National Health Survey (PNS 2013). Population survey representing the Brazilian population aged 18 years and older, with probability carried out sampling in three stages. The interview records of 60,202 individuals were obtained in the country. The respondent was presented with the short Rose questionnaire with three questions, adapted by Lawlor in 2003 and validated in Brazil, to identify angina pectoris grade I (mild) and II (moderate/severe). The prevalence rate was calculated with a 95% confidence interval (95%CI) according to sex, age, education, and race/color. The prevalence of mild angina (grade I) was of 7.6% (95%CI 7.2 - 8.0) for the entire population, more frequently in women - 9.1% (95%CI 8.5 - 9.7) - than in men - 5.9% (95%CI 5.3 - 6.4). The frequency of moderate/severe angina (grade II) was of 4.2 (95%CI 3.9 - 4.5), also more common in women - 5.2% (95%CI 4.7 - 5.6) - than in men - 3.0% (95%CI 2.7 - 3.4). The prevalence of angina by age group increased progressively with age. The prevalence of angina of any sort was inverse to years of formal study. Despite the higher value of the presence of angina in black people, there was no significant difference by race/skin color. The high prevalence rate of angina pectoris in the population aged 18 years and above was consistent with studies in other countries, revealing the importance of coronary heart disease as a public health problem.

Surveys were conducted in 2014 and 2015 in Southern and Northern Benin, respectively, to identify the viruses infecting peppers (Capsicum spp.). The samples were screened by ELISA for cucumber mosaic virus (CMV), pepper veinal mottle virus (PVMV), potato virus Y (PVY) and tomato yellow leaf curl virus (TYLCV). A generic reverse transcription PCR (RT-PCR) was used to test for the presence of poleroviruses. ELISA tests confirmed the prevalence of all viruses, while the RT-PCR detected pepper vein yellows virus (PeVYV) which is reported for the first time in Benin. A further, divergent polerovirus isolate was detected from a single pepper sample originating from southern Benin. Screening of samples collected from solanaceous plants during virus surveys in Mali (conducted in 2009) also detected this divergent polerovirus isolate in two samples from African eggplants. The complete genome sequence was obtained from the Mali isolate using transcriptome sequencing and by conventional Sanger sequencing of overlapping RT-PCR products. Based on the sequence characteristics of this isolate we propose a new polerovirus species, African eggplant yellowing virus (AeYV).

To provide estimates of the prevalence of obesity, overweight and body fat distribution among the adult population of Greece. Epidemiological, cross-sectional nationwide survey providing self-reported data. A total of 17,341 men and women aged from 20 to 70 years and classified into five 10-year age groups participated. The selection was conducted by stratified sampling through household family members of Greek children attending school. The participants reported data on weight, height, waist and hip circumference. BMI and waist-to-hip ratio were calculated. Abdominal obesity was defined as waist circumference > or = 102 cm in men and > or = 88 cm in women. In the total population, the mean BMI was 26.5 kg/m2, (27.3 in men, 25.7 in women). The overall prevalence of obesity was 22.5%, (26% in men, 18.2% in women) while that of overweight was 35.2% (41.1% in men, 29.9% in women). The percentages of obesity and overweight in men were similar in almost all age groups, while in women they progressively increased with age. Abdominal obesity was more frequent among women than men (35.8 vs. 26.6%, respectively), especially after the age of 50. Excess body weight is reaching epidemic proportions in Greece and obesity rates are among the highest, if not the highest, in Western society. The problem affects particularly men, and women after menopause. Interestingly, more women than men present with abdominal obesity. Preventive and treatment strategies are urgently needed to stop the obesity epidemic in this Mediterranean European country. Copyright 2006 S. Karger AG, Basel.

Bronchial asthma is a common but important chronic disease in children in all over the world. To take measures against prevalence of childhood asthma, many researchers have surveyed the actual statuses of childhood asthma in developed countries, but in most Asia-Pacific developing countries including Mongolia such surveys have never been sufficiently conducted until now. We have thought that this survey, though performed in 2009, will give important and meaningful information even now in taking measures to prevent prevailing bronchial asthma in children in Mongolia or the countries under similar statuses. The asthma prevalence and patient background information in Mongolian children aged 6-7 living in Ulaanbaatar were examined using a written questionnaire modified for their parents from that prepared by the International Study of Asthma and Allergies in Childhood (ISAAC). The estimated prevalence of asthma in Mongolian children was 20.9%. The following 3 risk factors were found to be related to asthma: (1) having allergic rhinitis symptoms, (2) mothers' smoking, and (3) history of severe respiratory infection before 1-year-old. The asthma prevalence in Mongolian children was higher than that in the world and Asia-Pacific countries reported by ISAAC. The higher prevalence was probably attributable to households' (especially mothers) smoking in draft-free houses designed for the cold area and severe air-pollution due to rapid industrialization and urbanization in Mongolia. Smoking prohibition in the mother (including family members) and a reduction of exposure to air pollutants are urgently needed to prevent developing childhood asthma. Copyright © 2015 The Authors.

Familial hypercholesterolemia (FH) is a genetic disorder characterized by high levels of low density lipoprotein cholesterol (LDL-C) predisposing to premature cardiovascular disease. Its prevalence varies and has been estimated around 1 in 200-500. The Heredity survey evaluated the prevalence of potential FH and the therapeutic approaches among patients with established coronary artery disease (CAD) or peripheral artery disease (PAD) in which it is less well documented. Data were collected in patients admitted to programs of rehabilitation and secondary prevention in Italy. Potential FH was estimated using Dutch Lipid Clinic Network (DLCN) criteria. Potential FH was defined as having a total score≥6. Among the 1438 consecutive patients evaluated, the prevalence of potential FH was 3.7%. The prevalence was inversely related to age, with a putative prevalence of 1:10 in those with Definite FH (DLCN score>8) had the highest percentages of patients after an ACS (75% vs 52.5% in the whole study population). At discharge, most patients were on high intensity statin therapy, but despite this, potential FH group still had a higher percentage of patients with LDL-C levels not at target and having a distance from the target higher than 50%. Among patients with established coronary heart disease, the prevalence of potential FH is higher than in the general population; the results suggest that a correct identification of potential FH, especially in younger patients, may help to better manage their high cardiovascular risk.

Bullying is common among young students, and cyberbullying has increased due to the use of technology. This study investigates the prevalence of bullying and cyberbullying among high school students and the emotional effects of bullying on students. Students at East Chapel Hill High School, Chapel Hill, North Carolina completed the Gatehouse Bullying Scale and the Peer Relations Questionnaire. They answered questions regarding how often they had experienced certain types of bullying in school and the emotional effects the bullying had on them. The combined results from both surveys indicated that the prevalence of bullying was 55% with 18% of respondents reporting cyberbullying. Teasing and name-calling were the most common types of bullying, as 40% of students reported having been teased or called names. The most serious type of bullying, being threatened with harm, hit, or kicked, occurred in 20% of boys and 8% of girls, with 25% of respondents reported "quite upset" by the experience. The majority (79%) of students who had been bullied did not share with anyone about being bullied, and of those who did, only 50% were taken seriously. Bullying is still prevalent among high school students, and cyberbullying is becoming more widespread. Most victims do not share their bullying experience, and if they did, only half believe they are taken seriously. Both bullying among students in school and cyberbullying deserve attention due to their potentially devastating effects on victims.

Chronic disease prevalence from Italian administrative databases in the VALORE project: a validation through comparison of population estimates with general practice databases and national survey

Science.gov (United States)

2013-01-01

Background Administrative databases are widely available and have been extensively used to provide estimates of chronic disease prevalence for the purpose of surveillance of both geographical and temporal trends. There are, however, other sources of data available, such as medical records from primary care and national surveys. In this paper we compare disease prevalence estimates obtained from these three different data sources. Methods Data from general practitioners (GP) and administrative transactions for health services were collected from five Italian regions (Veneto, Emilia Romagna, Tuscany, Marche and Sicily) belonging to all the three macroareas of the country (North, Center, South). Crude prevalence estimates were calculated by data source and region for diabetes, ischaemic heart disease, heart failure and chronic obstructive pulmonary disease (COPD). For diabetes and COPD, prevalence estimates were also obtained from a national health survey. When necessary, estimates were adjusted for completeness of data ascertainment. Results Crude prevalence estimates of diabetes in administrative databases (range: from 4.8% to 7.1%) were lower than corresponding GP (6.2%-8.5%) and survey-based estimates (5.1%-7.5%). Geographical trends were similar in the three sources and estimates based on treatment were the same, while estimates adjusted for completeness of ascertainment (6.1%-8.8%) were slightly higher. For ischaemic heart disease administrative and GP data sources were fairly consistent, with prevalence ranging from 3.7% to 4.7% and from 3.3% to 4.9%, respectively. In the case of heart failure administrative estimates were consistently higher than GPs’ estimates in all five regions, the highest difference being 1.4% vs 1.1%. For COPD the estimates from administrative data, ranging from 3.1% to 5.2%, fell into the confidence interval of the Survey estimates in four regions, but failed to detect the higher prevalence in the most Southern region (4.0% in

Background The aim of this study is to estimate the lifetime and 12-month prevalence, severity, and treatment of Diagnostic and Statistical Manual of Mental Disorders 4th ed. (DSM-IV) mental disorders in Japan based on the final data set of the World Mental Health Japan Survey conducted in 2002–2006. Methods Face-to-face household interviews of 4,130 respondents who were randomly selected from Japanese-speaking residents aged 20 years or older were conducted from 2002 to 2006 in 11 community populations in Japan (overall response rate, 56%). The World Mental Health version of the World Health Organization Composite International Diagnostic Interview (WMH-CIDI), a fully structured lay administered psychiatric diagnostic interview, was used for diagnostic assessment. Results Lifetime/12-month prevalence of any DSM-IV common mental disorders in Japan was estimated to be 20.3/7.6%. Rank-order of four classes of mental disorders was anxiety disorders (8.1/4.9%), substance disorders (7.4/1.0%), mood disorders (6.5/2.3%), and impulse control disorders (2.0/0.7%). The most common individual disorders were alcohol abuse/dependence (7.3/0.9%), major depressive disorder (6.1/2.2%), specific phobia (3.4/2.3%), and generalized anxiety disorder (2.6/1.3%). While the lifetime prevalence of any mental disorder was greater for males and the middle-aged, the persistence (proportion of 12-month cases among lifetime cases) of any mental disorder was greater for females and younger respondents. Among those with any 12-month disorder, 15.3% were classified as severe, 44.1% moderate, and 40.6% mild. Although a strong association between severity and service use was found, only 21.9% of respondents with any 12-month disorder sought treatment within the last 12 months; only 37.0% of severe cases received medical care. The mental health specialty sector was the most common resource used in Japan. Although the prevalence of mental disorders were quite low, mental disorders were the second

This study describes the levels and patterns of television (TV) viewing in Brazilian adults and investigates associations of TV viewing with hypertension, type 2 diabetes, and heart disease. Data from the Brazilian Health Survey, a nationally representative survey that was conducted in 2013 (N = 60,202 men and women aged ≥18 y), were used. Information regarding TV viewing, physician diagnoses of type 2 diabetes, hypertension, and heart disease was collected via interview-administered questionnaire. Data on covariables (including chronological age, educational status, skin color, sodium consumption, sugar consumption, tobacco smoking, alcohol consumption, and leisure-time physical activity) were also self-reported. Logistic regression models and population attributable fractions were used for the etiological analyses. The prevalence (95% confidence interval) of >4 hours per day of TV viewing was 12.7% (12.0-13.4) in men and 17.5% (16.8-18.3) in women. Men and women being younger or older, moderately educated, living alone, smoking tobacco, and drinking alcohol were associated with higher reported TV viewing time. Odds ratios (95% confidence interval) revealed that >4 hours per day of TV viewing was associated with type 2 diabetes [male: 1.64 (1.23-2.17) and female: 1.33 (1.09-1.63)], hypertension [male: 1.36 (1.14-1.63) and female: 1.20 (1.05-1.37)], and heart disease [male: 1.96 (1.43-2.69) and female: 1.30 (1.00-1.68)]. Exceeding 4 hours per day of TV viewing was responsible for 6.8% of type 2 diabetes, 3.7% of hypertension, and 7.5% of heart disease cases. Independent of covariates, >4 hours per day of TV viewing was associated with type 2 diabetes, hypertension, and heart disease. High volumes of TV viewing are prevalent and appear to contribute to chronic disease burden.

Adaptive geostatistical sampling enables efficient identification of malaria hotspots in repeated cross-sectional surveys in rural Malawi.

Directory of Open Access Journals (Sweden)

Alinune N Kabaghe

Full Text Available In the context of malaria elimination, interventions will need to target high burden areas to further reduce transmission. Current tools to monitor and report disease burden lack the capacity to continuously detect fine-scale spatial and temporal variations of disease distribution exhibited by malaria. These tools use random sampling techniques that are inefficient for capturing underlying heterogeneity while health facility data in resource-limited settings are inaccurate. Continuous community surveys of malaria burden provide real-time results of local spatio-temporal variation. Adaptive geostatistical design (AGD improves prediction of outcome of interest compared to current random sampling techniques. We present findings of continuous malaria prevalence surveys using an adaptive sampling design.We conducted repeated cross sectional surveys guided by an adaptive sampling design to monitor the prevalence of malaria parasitaemia and anaemia in children below five years old in the communities living around Majete Wildlife Reserve in Chikwawa district, Southern Malawi. AGD sampling uses previously collected data to sample new locations of high prediction variance or, where prediction exceeds a set threshold. We fitted a geostatistical model to predict malaria prevalence in the area.We conducted five rounds of sampling, and tested 876 children aged 6-59 months from 1377 households over a 12-month period. Malaria prevalence prediction maps showed spatial heterogeneity and presence of hotspots-where predicted malaria prevalence was above 30%; predictors of malaria included age, socio-economic status and ownership of insecticide-treated mosquito nets.Continuous malaria prevalence surveys using adaptive sampling increased malaria prevalence prediction accuracy. Results from the surveys were readily available after data collection. The tool can assist local managers to target malaria control interventions in areas with the greatest health impact and is

To present estimations obtained from a population-level survey conducted in Mexico of prevalence rates of mono-, poly- and multidrug-resistant strains among newly diagnosed cases of pulmonary tuberculosis (TB), as well as the main factors associated with multidrug resistance (combined resistance to isoniazid and rifampicin). Study data came from the National Survey on TB Drug Resistance (ENTB-2008), a nationally representative survey conducted during 2008-2009 in nine states with a stratified cluster sampling design. Samples were obtained for all newly diagnosed cases of pulmonary TB in selected sites. Drug susceptibility testing (DST) was performed for anti-tuberculosis drugs. DST results were obtained for 75% of the cases. Of these, 82.2% (95%CI 79.5-84.7) were susceptible to all drugs. The prevalence of multidrug-resistant TB (MDR-TB) was estimated at 2.8% (95%CI 1.9-4.0). MDR-TB was associated with previous treatment (OR 3.3, 95%CI 1.1-9.4). The prevalence of drug resistance is relatively low in Mexico. ENTB-2008 can be used as a baseline for future follow-up of drug resistance.

Discrepancy between prevalence and perceived effectiveness of treatment methods in myofascial pain syndrome: Results of a cross-sectional, nationwide survey

Directory of Open Access Journals (Sweden)

Freiberg Florentina

2010-02-01

Full Text Available Abstract Background Myofascial pain is a common dysfunction with a lifetime prevalence affecting up to 85% of the general population. Current guidelines for the management of myofascial pain are not available. In this study we investigated how physicians on the basis of prescription behaviour evaluate the effectiveness of treatment options in their management of myofascial pain. Methods We conducted a cross-sectional, nationwide survey with a standardized questionnaire among 332 physicians (79.8% male, 25.6% female, 47.5 ± 9.6 years experienced in treating patients with myofascial pain. Recruitment of physicians took place at three German meetings of pain therapists, rheumatologists and orthopaedists, respectively. Physicians estimated the prevalence of myofascial pain amongst patients in their practices, stated what treatments they used routinely and then rated the perceived treatment effectiveness on a six-point scale (with 1 being excellent. Data are expressed as mean ± standard deviation. Results The estimated overall prevalence of active myofascial trigger points is 46.1 ± 27.4%. Frequently prescribed treatments are analgesics, mainly metamizol/paracetamol (91.6%, non-steroidal anti-inflammatory drugs/coxibs (87.0% or weak opioids (81.8%, and physical therapies, mainly manual therapy (81.1%, TENS (72.9% or acupuncture (60.2%. Overall effectiveness ratings for analgesics (2.9 ± 0.7 and physical therapies were moderate (2.5 ± 0.8. Effectiveness ratings of the various treatment options between specialities were widely variant. 54.3% of all physicians characterized the available treatment options as insufficient. Conclusions Myofascial pain was estimated a prevalent condition. Despite a variety of commonly prescribed treatments, the moderate effectiveness ratings and the frequent characterizations of the available treatments as insufficient suggest an urgent need for clinical research to establish evidence-based guidelines for the

Population estimates on disability prevalence inform policy makers and public health professionals. Understanding how factors capable of affecting measurement (e.g., proxy-report) vary in the population is important for establishing level of confidence in sample-derived population estimates. To establish how use of proxy-reports varies by six disability types stratified by sex, race-ethnicity, and age group. Specific aim is achieved by investigating the number of proxy-reports used amongst the disable population. Cross-sectional study using American Community Survey (ACS) Public Use Microdata Sample (PUMS) 3-year file collected during 2009-2011 survey period. Community-dwelling population in continental United States (US). The unweighted count of 6,003,183 individuals in the microdata are said to represent about 193,277,485 individuals in the continental US population. Stratified disability period estimates are computed. Amongst the disable: the number of proxy-reports; allocations; and Person Inflation Ratios (PRIs) are presented by disability type. Half of all the reported disabilities are derived through the use of proxy-report. In addition, high rates of item-allocation and PRIs are generally found in race-ethnic minorities. Proxy-report use and PRIs are lower for those aged > 65-but not allocation rates. Although use of proxy report in the ascertainment of disability varies in complex ways, data suggest prevalence of proxy reports is lowest amongst Non-Latino-Black females ages 21 to 64. Efforts toward providing clinicians with high quality descriptive epidemiology should continue as a reliable thermometer for measuring disability in the population is needed.

The aim of this study was to estimate the burden of childhood rickets-like bone deformity in a rural region of West Africa where rickets has been reported in association with a low calcium intake. A population-based survey of children aged 0.5-17.9 years living in the province of West Kiang, The Gambia was conducted in 2007. 6221 children, 92% of those recorded in a recent census, were screened for physical signs of rickets by a trained survey team with clinical referral of suspected cases. Several objective measures were tested as potential screening tools. The prevalence of bone deformity in children rickets on X-ray at the time of medical examination. This emphasises the difficulties in comparing prevalence estimates of rickets-like bone deformities from population surveys and clinic-based studies. Interpopliteal distance showed promise as an objective screening measure for bow-leg deformity. In conclusion, this population survey in a rural region of West Africa with a low calcium diet has demonstrated a significant burden of rickets-like bone deformity, whether based on physical signs under survey conditions or after clinical examination, especially in boys < 5.0 years.

The aim of this project was to detail the costs associated with the high prevalence mental disorders (depression, anxiety-related and substance use) in Australia, using community-based, nationally representative survey data. Respondents diagnosed, within the preceding 12 months, with high prevalence mental disorders using the Confidentialised Unit Record Files of the 2007 National Survey of Mental Health and Wellbeing were analysed. The use of healthcare resources (hospitalisations, consultations and medications), productivity loss, income tax loss and welfare benefits were estimated. Unit costs of healthcare services were obtained from the Independent Hospital Pricing Authority, Medicare and Pharmaceutical Benefits Scheme. Labour participation rates and unemployment rates were determined from the National Survey of Mental Health and Wellbeing. Daily wage rates adjusted by age and sex were obtained from Australian Bureau of Statistics and used to estimate productivity losses. Income tax loss was estimated based on the Australian Taxation Office rates. The average cost of commonly received Government welfare benefits adjusted by age was used to estimate welfare payments. All estimates were expressed in 2013-2014 AUD and presented from multiple perspectives including public sector, individuals, private insurers, health sector and societal. The average annual treatment cost for people seeking treatment was AUD660 (public), AUD195 (individual), AUD1058 (private) and AUD845 from the health sector's perspective. The total annual healthcare cost was estimated at AUD974m, consisting of AUD700m to the public sector, AUD168m to individuals, and AUD107m to the private sector. The total annual productivity loss attributed to the population with high prevalence mental disorders was estimated at AUD11.8b, coupled with the yearly income tax loss at AUD1.23b and welfare payments at AUD12.9b. The population with high prevalence mental disorders not only incurs substantial cost to

The current exploratory study addresses this gap using the validated PainDetect questionnaire as a screener for probable NeP in a general-population health survey conducted with a multimodal recruitment strategy to maximize demographic representativeness. Materials and methods: Adult respondents were recruited from a combination of Internet panels, telephone lists, address lists, mall-based interviews, and store-receipt invitations using a random stratified-sampling framework, with strata defined by age, sex, and race/ethnicity. Older persons and minorities were oversampled to improve prevalence estimates. Results were weighted to match the total adult US population using US Census data. Demographic information was collected, and respondents who experienced physical pain in the past 12 months completed the PainDetect and provided additional pain history. A cutoff score of 19 or greater on the PainDetect was used to define probable NeP. Results: A total of 24,925 respondents (average response rate 2.5% provided demographic data (52.2% female, mean age 51.5 years; 15,751 respondents reported pain (63.7%, of which 2,548 (15.7%, 95% confidence interval 14.9%–16.5% had probable NeP based on the PainDetect, which was 10% (95% confidence interval 9.5%–10.5% of all respondents.

Objective: To investigate the prevalence of HIV infection/STD and related factors in Vietnamese female sex workers (FSWs). Methods: Consecutive cross-sectional surveys were conducted in June 2014, December 2014, May 2015 and November 2015 in Hekou, a county bordering Vietnam in Yunnan province. Convenience sampling were adopted to select 1 058 Vietnamese FSWs aged>16 years. Questionnaire interview were used to collect the information about their demographics, sexual behaviors and drug use. Serum and urine samples were collected for HIV infection/STD detection and drug use test. Trend χ (2) test was applied for HIV infection/STD and drug use trend analysis. Multivariate logistic regression model was used to identify the related factors. Results: The consecutive cross sectional surveys indicated that the prevalence of HIV infection in Vietnamese FSWs were 3.20 % (7/219), 2.04 % (5/245), 1.89 % (5/265) and 1.82 % (6/329) respectively; the HSV-2 positive rates were 57.08 % (125/219), 58.37 % (143/245), 38.11 % (101/265) and 51.06 % (168/329) respectively. In addition, the prevalence of syphilis were 0.91 % , 1.51 % , 0.75 % and 1.22 % respectively. HSV-2 infection prevalence showed a downward trend ( χ (2)=4.823, P =0.028). By logistic regression analysis, the related factors for HIV infection in Vietnamese FSWs were being amphetamine type stimulants (ATS) positive ( OR =10.18, 95 %CI : 4.33-23.92) and being HSV-2 positive ( OR =2.89, 95 %CI : 1.09-7.88); Age ( OR =1.88, 95 %CI : 1.32-2.61), no-paid sexual partner ( OR =1.59, 95 %CI : 1.26-2.01) and being ATS positive ( OR =2.48, 95 %CI : 1.10-5.57) were related factors for HSV-2 infection. Conclusions: Compared with the results of previous studies, the HIV infection prevalence declined in Vietnamese FSWs, but the HSV-2 infection prevalence was still high. The association between ATS use and HIV infection/STD suggested the necessity of strengthening AIDS intervention in Vietnamese FSWs, including the control of new

The US Affiliated Pacific region's childhood obesity prevalence has reached epidemic proportions. To guide program and policy development, a multi-site study was initiated, in collaboration with partners from across the region, to gather comprehensive information on the regional childhood obesity prevalence. The environmental and cultural diversity of the region presented challenges to recruiting for and implementing a shared community-based, public health research program. This paper presents the strategies used to recruit families with young children (n = 5775 for children 2 - 8 years old) for obesity-related measurement across eleven jurisdictions in the US Affiliated Pacific Region. Data were generated by site teams that provided summaries of their recruitment strategies and lessons learned. Conducting this large multi-site prevalence study required considerable coordination, time and flexibility. In every location, local staff knowledgeable of the community was hired to lead recruitment, and participant compensation reflected jurisdictional appropriateness (e.g., gift cards, vouchers, or cash). Although recruitment approaches were site-specific, they were predominantly school-based or a combination of school- and community-based. Lessons learned included the importance of organization buy-in; communication, and advance planning; local travel and site peculiarities; and flexibility. Future monitoring of childhood obesity prevalence in the region should consider ways to integrate measurement activities into existing organizational infrastructures for sustainability and cost-effectiveness, while meeting programmatic (e.g. study) goals.

The majority of adults who smoke cigarettes initiated the habit when they were adolescents or young adults. While rates of smoking and associated factors are known among 13-15 year olds in Malawi, correlates of cigarette smoking among adolescents in a national representative sample in Malawi have not been studied. We, therefore, carried out this study to estimate the prevalence of current smoking and determine its correlates in a nationally representative sample of in-school adolescents in Malawi. An analysis of the Malawi Global Youth Tobacco Survey (GYTS) 2005 was conducted. Using logistic regression analysis, we estimated the association between current cigarette smoking and potential explanatory variables. Overall, 2.5% of adolescents (3.2% among males, and 1.8% among females) were current cigarette smokers. Smoking among parents was 9.6% with no significant difference between males and females (10.3% versus 10.1%). Stronger associations with smoking were observed for friends smoking status (AOR=3.07, 95%CI 2.99, 3.16), receiving pocket money (AOR=3.06, 95%CI 2.98, 3.14), and perception that smoking increases body weight (AOR=2.98, 95%CI 2.81, 3.16). Students who thought that cigarette smoking is harmful to health were 56% (AOR=0.44, 95%CI 0.43, 0.45) less likely to smoke than students who thought otherwise. Despite being the world's second leading grower of tobacco, the prevalence of cigarette smoking among adolescent is lower than has been reported elsewhere.

Background In recent years, some reports have suggested that papillary thyroid cancers are more frequently associated with lymphocytic thyroiditis or Hashimoto's thyroiditis. This study investigated a potential increase in the prevalence of chronic lymphocytic thyroiditis among papillary thyroid cancer patients. Materials and Methods We used national epidemiological survey data on thyroid cancer patients diagnosed in 1999, 2005, and 2008. A retrospective medical record survey was conducted by representative sampling of a national cancer incidence database. The analysis included 5,378 papillary thyroid cancer patients aged 20–79 years. We calculated the age-standardized prevalence and age-adjusted prevalence ratios using a binomial regression model with a log link for the prevalence of chronic lymphocytic thyroiditis among papillary thyroid cancer patients by sex for each year. Results The prevalence of chronic lymphocytic thyroiditis among papillary thyroid cancer patients was 4.0% and 12.8% for men and women in 1999, 6.5% and 24.6% in 2005, and 10.7% and 27.6% in 2008, respectively. Between 1999 and 2008, the age-standardized prevalence of chronic lymphocytic thyroiditis increased 4.1-fold in male patients and 2.0-fold in female patients with papillary thyroid cancer. The prevalence of other thyroid diseases, however, did not increase in either gender. Conclusions Among Korean papillary thyroid cancer patients, the prevalence of chronic lymphocytic thyroiditis increased between 1999 and 2008, whereas the prevalence of other thyroid disorders did not change.

Urbanisation has been described as a key driver of the evolving non-communicable disease (NCD) epidemic. In Africa, hypertension is the commonest cardiovascular problem. We determined the prevalence and risk factor correlates of hypertension in the largest Nairobi slum. In 2010 we conducted a population-based household survey in Kibera, a large informal settlement in Nairobi City; utilising cluster sampling with probability proportional to size. Households were selected using a random walk method. The WHO instrument for stepwise surveillance (STEPS) of chronic disease risk factors was administered by trained medical assistants, who also recorded blood pressure (BP) and anthropometric measures. BP was recorded using a mercury sphygmomanometer utilising the American Heart Association guidelines. Hypertension was defined as per the 7th Report of the Joint National Committee or use of prescribed antihypertensive medication. Those with hypertension or with random capillary blood sugar (RCBS) >11.1 mmol/l had an 8 hours fasting venous blood sugar sample drawn. Age standardised prevalence was computed and multivariate analysis to assess associations. We screened 2200 and enrolled 2061 adults; 50.9% were males; mean age was 33.4 years and 87% had primary level education. The age-standardised prevalence of hypertension (95% CI) was 22.8% (20.7, 24.9). 20% (53/258) were aware of their hypertensive status; 59.3% had pre-hypertension; 80% reported high levels of physical activity and 52% were classified as harmful alcohol drinkers; 10% were current smokers and 5% had diabetes. Majority of males had normal BMI and waist circumference, whereas a third of females were obese or overweight and 40% had central obesity. Older age, higher general and central obesity were independently associated with hypertension and higher SBP and DBP readings. Our findings of high prevalence of hypertension, in association with excess body weight in this poor urban slum community, point to the need

Education is important in improving economies and creating literate, self-reliant and healthy societies. However, hunger is a barrier to basic education in Malawi. Hunger is also associated with a number of health risk behaviours, such as bullying, suicide ideation and unhygienic behaviours that may jeopardize the future of children. There are, however, limited data on the prevalence and associated factors of hunger among school children in Malawi. The study used data from the Malawi Global School-Based Health Survey conducted in 2009 to estimate the prevalence of self-reported hunger within the last 30 days among primary and secondary school age group. It also assessed the association between self-reported hunger and some selected list of independent variables using frequency distribution, chi-squared test and logistic regression. A total of 2359 students were available for analysis. The overall self-reported prevalence of hunger within the last 30 days was 12.5% (18.9% (172) in the rural and 8.3% (115) in urban areas; and 11.9%(123) for male and 12.5(148) for female children). In the final analysis, geographical location, eating fruits, having been bullied, suicide ideation, and washing hands with soap were significantly associated with hunger. Hunger in both primary and secondary school children in Malawi is a major social problem. The design of school feeding programmes aimed to reduce hunger should incorporate the factors identified as associated with hunger.

To study the prevalence and determinants of cigarette smoking in Morocco. A sample of 9,195 individuals aged 15-90 years, were randomly selected, using a stratified cluster sampling technique. A cross-sectional, household, community-based survey was conducted using a tested questionnaire. The interview covered personal, social and educational characteristics of the respondents and their smoking status. The association between current smoking and sociodemographic variables was estimated. The overall prevalence of current smoking was 31.5% for males and 3.1% for females. In men, smoking was associated with lower educational level. In women, it was associated with higher educational level and social class. Cigarette smoking remains an important public health problem in Morocco. A comprehensive strategy for tobacco control is needed.

To estimate the prevalence of lower urinary tract symptoms, urinary incontinence and overactive bladder in western Turkey. This cross-sectional, population-based survey was carried out between May and October 2012. A random sample of 2128 women and men aged ≥18 years was selected from the health registries. A questionnaire including sociodemographic data, comorbid conditions, lower urinary tract symptoms, overactive bladder and urinary incontinence symptoms, body mass index, vital signs, and dipstick urinalysis was developed. The questions were answered by the participants, and remaining data were provided by the site staff. International Continence Society definitions were used. A total of 1571 (74%) individuals agreed to participate, and analysis were carried out on 1555 people (636 men [40.9%] and 919 women [59.1%]) after 16 individuals with a nitrite-positive dipstick test were excluded. Lower urinary tract symptoms were reported by 71.0% of the study population. The prevalence of storage, voiding and post-micturition symptoms were 56.1% (44.2% men, 64.1% women), 39.3% (40.9% men, 37.8% women) and 30.7% (38.6% men, 28.7% women), respectively. The most prevalent storage symptom was urgency, which was reported by 29.3% of the study population (20.1% men, 35.6% women). The prevalence of urge, stress and mixed urinary incontinence were: 6.5% (3.9% men, 8.2% women), 14.1% (3.9% men, 21.2% women) and 5.6% (0.8% men, 9.0% women), respectively. The present study is the first and largest population-based survey evaluating the prevalence of lower urinary tract symptoms, urinary incontinence and overactive bladder in Turkey. Our findings show these symptoms are highly prevalent in western Turkey. © 2014 The Japanese Urological Association.

Objective: To investigate the epidemiologic characteristics of diabetes mellitus (DM) in Uygur residents in Kashgar of Xinjiang. Methods: The survey was conducted among the Uygur residents aged ≥18 years selected through stratified cluster sampling in Kashgar by means of questionnaire survey, physical examination and basic laboratory test. The prevalence of different groups were calculated and risk factors of DM was analyzed by logistic vegression model. Results: A total of 4 608 adults were surveyed. The prevalence of DM was 11.31 % (standardized prevalence: 10.59 % ) and the prevalence was 13.65 % (standardized prevalence: 12.34 % ) in males and 10.04 % (standardized prevalence: 9.83 % ) in females. The prevalence increased with age. The prevalence of DM was higher than the prevalence of impaired fasting glucose (IFG) in people aged >60 years, especially in females. The rates of awareness, treatment and control of DM were 28.02 % , 21.31 % and 5.57 % , respectively. Multivariate logistic regression analysis indicated that people aged 45-55, 55-65 and >65 years had higher risk of DM and the odds ratio were 2.08 (95 %CI : 1.24-3.48), 2.73 (95 %CI : 1.63-4.56) and 3.90 (95 %CI : 2.24-6.78) for men and 2.63 (95 % CI : 1.71-4.02), 3.14 (95 %CI : 2.00-4.94) and 5.56 (95 %CI : 3.47-8.92) for woman, respectively. Family history of DM ( OR =2.88 for men, 95 % CI : 1.45-5.72; OR =2.52 for women, 95 % CI : 1.49-4.26) and BMI≥28.0 kg/m(2) ( OR =1.77 for men, 95 % CI : 1.19-2.64, OR =1.80 for women, 95 % CI : 1.30-2.50) were also risk factors for DM. Conclusion: The prevalence of DM was high in Uygur residents in Kashgar, but the rate of awareness, treatment and control of DM were low. It is necessary to improve the detection rate of DM and conduct targeted prevention and control of DM.

Malnutrition among the indigenous early childhood population is still currently a serious public health problem, and given that no specific studies affording the possibility of knowing the nutritional condition of this population, the question was posed of identifying the prevalence of malnutrition among the indigenous population of Mexico by means of the 1999 National Nutrition Survey. A rural sample was selected from the Northern, Central and Southern regions where 70% or more of the population speak an indigenous language. The weight/age, height/age and weight/height Score Z desviations was calculated for 3,236 preschoolers and 4,899 school-age children. Nationwide and by regions, there were no difference by age group regarding the prevalences of the three indicators. By regions, for preschoolers, the South showed the highest prevalences of underheight (69.8%) and underweight (49.8%) than the North (respectively 36.1% and 22.6%), entailing statistically significant differences (p = 0.0002 and p = 0.04). For overweight and obesity, the North showed a 14.2% prevalence, and the South 5.6% (p < 0.05) for the same age group. The nutritional condition of the children studied reveals a geographical polarization, the greatest prevalences related to underheight and underweight children being found in southern Mexico, whilst those due to overalimentation were located in the North, this phenomenon possibly being due to lifestyles and availability of food differing from one region to the other.

Full Text Available The objective of this study was to investigate and summarize the levels of incidence of Salmonella spp., Listeria monocytogenes, Staphylococcus aureus and Campylobacter spp. in poultry meat commercialized in Europe. After systematic review, incidence data and study characteristics were extracted from 78 studies conducted in 21 European countries. Pooled prevalence values from 203 extracted observations were estimated from random-effects meta-analysis models adjusted by pathogen, poultry type, sampling stage, cold preservation type, meat cutting type and packaging status. The results suggest that S. aureus is the main pathogen detected in poultry meat (38.5%; 95% CI: 25.4–53.4, followed by Campylobacter spp. (33.3%; 95% CI: 22.3–46.4%, while L. monocytogenes and Salmonella spp. present lower prevalence (19.3%; 95% CI: 14.4–25.3% and 7.10%; 95% CI: 4.60–10.8%, respectively. Despite the differences in prevalence, all pathogens were found in chicken and other poultry meats, at both end-processing step and retail level, in packed and unpacked products and in several meat cutting types. Prevalence data on cold preservation products also revealed that chilling and freezing can reduce the proliferation of pathogens but might not be able to inactivate them. The results of this meta-analysis highlight that further risk management strategies are needed to reduce pathogen incidence in poultry meat throughout the entire food chain across Europe, in particular for S. aureus and Campylobacter spp.

Dwellers of urban informal settlements in developing countries are consistently reported to be victims of high diarrhoea prevalence. Studies have frequently reported the association between high diarrhoea prevalence and other factors, such as poor living conditions, inadequate hygiene, and sanitation in these settings. However, little is known about the dynamics of diarrhoea prevalence in mountainous urban informal settlements similar to the Rwandan context. This study was conducted in the Matyazo cell of Huye town to review the prevalence and correlates of diarrhoea. A survey of 214 households and transect walks in the neighbourhoods were conducted during the rainy and dry seasons. Logistic regression was used to analyse the survey data while the thematic analysis technique was used to analyse qualitative data. Results indicated a substantial reduction of diarrhoea prevalence from the rainy to the dry season. It was also found that the prevalence was unequally distributed in the neighbourhoods according to household location. After controlling for other household characteristics and sanitation conditions of around homes, the study indicated that households established at 1800 metres or more above sea level were protected against diarrhoea during both rainy seasons (Adjusted Odds Ratio_ AOR: .42, 95% Confidence Interval_ CI: .13-.81) and dry seasons (AOR: .58, CI: .12-.90) while households found further from the road were likely to suffer from diarrhoea during rainy seasons (AOR: 3.32, CI: 1.47-7.48) as well as in dry seasons (AOR: 1.60, CI: 1.26-4.10). Poor sanitation within and around homes was also found to be associated with the increase of diarrhoea in either season. However, the evidence was not sufficient enough to confirm a significant association between diarrhoea prevalence and other household characteristics. We believe this is due to the strength of environmental factors in mountainous settings.

2015-08-01

The purpose of this study was to analyze the attitude of a group of cardiologists on the ethical conducts they would accept or adopt when encountered with different hypothetical situations of medical practice. Between August and September of 2011, 700 Argentine cardiologists were surveyed in situations which posed ethical dilemmas in the patient-physician relationship, among colleagues or involving financial agreements with employers or the pharmaceutical industry. Ethical conflicts were evidenced in a series of inappropriate conducts such as differential fees, trips and meals sponsored by laboratories, splitting fees, overbilling, self-referral, charging for patient referral, financial compensation for ordering medical procedures, and various situations derived from the relationship with employers. In general, financial compensation from the pharmaceutical industry was more accepted than the conflictive situations which directly involved patients, colleagues or employers. The rejection of these conducts, the physicians' deontological education and the improvement of financial and organizational conditions in medical practice will help to encourage better medical professionalism and avoid unseemly behaviors. © 2013 John Wiley & Sons Ltd.

To estimate the prevalence of obesity and overweight in children aged 2 to 14 years in Catalonia, its trends between 2006 and 2010-2012, and to evaluate social determinants and lifestyle associated with obesity. A cross-sectional study, using the data from 4,389 surveys from Catalonia Health Surveys of the years 2006 and 2010-2012, was conducted. Obesity and overweight were determined by World Health Organization criteria. Socioeconomic position, parent's education, usual diet and activity, and hours of sleep were assessed. The prevalence of obesity and overweight were: 15.4 and 20.2% in 2010-2012. The prevalence of obesity was higher in boys (15.5%) compared to girls (12.8%) (Pchildren ranging from 2 to 9 years old (17.5%) than children aged 10 to 14 years (7.7%) (Pobesity and overweight were similar to the prevalence in 2010-2012. Obesity was more frequent in children with parents with a low socioeconomic position and/or a primary or elementary parent's education. During the last 5 years (2006-2012), child obesity and overweight have remained stable in Catalonia, yet they are relatively high in Europe. Public health programmes against obesity must consider conducting an intersectional action taking social determinants and family life styles into account. Copyright © 2013 Elsevier España, S.L.U.

Full Text Available Abstract Background In the light of the universal healthcare coverage that was achieved in Thailand in 2002, policy makers have raised concerns about whether there is still unmet need within the population. Our objectives were to assess the annual prevalence, characteristics and reasons for unmet healthcare need in the Thai population in 2010 and to compare our findings with relevant international literature. Methods A standard set of OECD unmet need questionnaires was used in a nationally-representative household survey conducted in 2010 by the National Statistical Office. The prevalence of unmet need among respondents with various socio-economic characteristics was estimated to determine an inequity in the unmet need and the reasons behind it. Results The annual prevalence of unmet need for outpatient and inpatient services in 2010 was 1.4% and 0.4%, respectively. Despite this low prevalence, there are inequities with relatively higher proportion of the unmet need among Universal Coverage Scheme members, and the poor and rural populations. There was less unmet need due to cost than there was due to geographical barriers. The prevalence of unmet need due to cost and geographical barriers among the richest and poorest quintiles were comparable to those of selected OECD countries. The geographical extension of healthcare infrastructure and of the distribution of health workers is a major contributing factor to the low prevalence of unmet need. Conclusions The low prevalence of unmet need for both outpatient and inpatient services is a result of the availability of well-functioning health services at the most peripheral level, and of the comprehensive benefit package offered free of charge by all health insurance schemes. This assessment prompts a need for regular monitoring of unmet need in nationally-representative household surveys.

Obesity is associated with adverse health outcomes in people with and without disabilities; however, little is known about disability prevalence among people who are obese. The purpose of this study was to determine the prevalence and type of disability among obese adults in the United States. We analyzed pooled data from sample adult modules of the 2003-2009 National Health Interview Survey (NHIS) to obtain national prevalence estimates of disability, disability type, and obesity by using 30 questions that screened for activity limitations, vision and hearing impairment, and cognitive, movement, and emotional difficulties. We stratified disability prevalence by category of body mass index (BMI, measured as kg/m(2)): underweight, less than 18.5; normal weight, 18.5 to 24.9; overweight, 25.0 to 29.9; and obese, 30.0 or higher. Among the 25.3% of adult men and 24.6% of women in our pooled sample who were obese, 35.2% and 46.9%, respectively, reported a disability. In contrast, 26.7% of men and 26.8% women of normal weight reported a disability. Disability was much higher among obese women than among obese men (46.9% vs 35.2%, P < .001). Movement difficulties were the most common disabilities among obese men and women, affecting 25.3% of men and 37.9% of women. This research contributes to the literature on obesity by including disability as a demographic in characterizing people by body mass index. Because of the high prevalence of disability among those who are obese, public health programs should consider the needs of those with disabilities when designing obesity prevention and treatment programs.

Women are disproportionally affected by human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) in sub-Saharan Africa (SSA). The determinants of gender inequality in HIV/AIDS may vary across countries and require country-specific interventions to address them. This study aimed to identify the socio-demographic and behavioral characteristics underlying gender inequalities in HIV/AIDS in 21 SSA countries. We applied an extension of the Blinder-Oaxaca decomposition approach to data from Demographic and Health Surveys and AIDS Indicator Surveys to quantify the differences in HIV/AIDS prevalence between women and men attributable to socio-demographic factors, sexual behaviours, and awareness of HIV/AIDS. We decomposed gender inequalities into two components: the percentage attributable to different levels of the risk factors between women and men (the "composition effect") and the percentage attributable to risk factors having differential effects on HIV/AIDS prevalence in women and men (the "response effect"). Descriptive analyses showed that the difference between women and men in HIV/AIDS prevalence varied from a low of 0.68 % (P = 0.008) in Liberia to a high of 11.5 % (P distributions of HIV/AIDS risk factors, particularly age at first sex between women and men. In the majority of countries, however, observed gender inequalities in HIV/AIDS were chiefly explained by differences in the responses to risk factors; the differential effects of age, marital status and occupation on prevalence of HIV/AIDS for women and men were among the significant contributors to this component. In Cameroon, Guinea, Malawi and Swaziland, a combination of the composition and response effects explained gender inequalities in HIV/AIDS prevalence. The factors that explain gender inequality in HIV/AIDS in SSA vary by country, suggesting that country-specific interventions are needed. Unmeasured factors also contributed substantially to the difference in HIV

Urban slum populations in Africa continue to grow faster than national populations. Health strategies that focus on non-communicable diseases (NCD) in this segment of the population are generally lacking. We determined the prevalence of diabetes and associated cardiovascular disease (CVD) risk factors correlates in Kibera, Nairobi's largest slum. We conducted a population-based household survey utilising cluster sampling with probability proportional to size. Households were selected using a random walk method and consenting residents aged 18 years and above were recruited. The WHO STEPS instrument was administered. A random capillary blood sugar (RCBS) was obtained; known persons with diabetes and subjects with a RCBS >11.1 had an 8 hours fasting blood sugar (FBS) drawn. Diabetes was defined as a RCBS of  ≥ 11.1 mmol/l and a FBS of  ≥ 7.0 mmol/l, or a prior diagnosis or receiving diabetes drug treatment. Out of 2061 enrolled; 50.9% were males, mean age was 33.4 years and 87% had a minimum of primary education. Only 10.6% had ever had a blood sugar measurement. Age adjusted prevalence of diabetes was 5.3% (95% CI 4.2-6.4) and prevalence increased with age peaking at 10.5% (95% CI 6.8-14.3%) in the 45-54 year age category. Diabetes mellitus (DM) correlates were: 13.1% smoking, 74.9% alcohol consumption, 75.7% high level of physical activity; 16.3% obese and 29% overweight with higher rates in women.Among persons with diabetes the odds of obesity, elevated waist circumference and hypertension were three, two and three fold respectively compared to those without diabetes. Cardiovascular risk factors among subjects with diabetes were high and mirrored that of the entire sample; however they had a significantly higher use of tobacco. This previously unstudied urban slum has a high prevalence of DM yet low screening rates. Key correlates include cigarette smoking and high alcohol consumption. However high levels of physical activity were also reported. Findings

Prevalence and causes of ocular morbidity in Mbeere District, Kenya. Results of a population-based survey.

Kahaki Kimani

Full Text Available PURPOSE: Ocular morbidity (OM describes any eye disease regardless of resultant visual loss. Ocular morbidity may affect large numbers of people in low income countries and could lead to many episodes of care. However there is limited evidence about the prevalence of ocular morbidity or resulting health-seeking behavior. This study in Mbeere District, Kenya, set out to explore both these issues. METHODS: A cross-sectional household survey was conducted in 2011. Trained teams moved from house to house examining and questioning residents on ocular morbidity and health-seeking behavior. Data were collected on standardized proformas and entered into a database for analysis. RESULTS: 3,691 people were examined (response rate 91.7%. 15.52% (95% CI 13.86-16.92 had at least one ocular morbidity in at least one eye. The leading cause was presbyopia which affected 25.11% (95% CI 22.05-28.45 of participants over 35 and increased with age. Other leading causes of OM were conditions that affected the lens (32.58% and the conjunctiva (31.31%. No association was found between educational attainment or employment and OM. 9.63% (7.87-11.74 self-reported an ocular morbidity in the previous six months and 45.94% (95% CI 37.1-55.04 stated that they had sought treatment for the condition. CONCLUSION: A large number of people were affected by an ocular morbidity in this survey. Most of these people could potentially be managed in their own communities through primary care services (e.g. those with presbyopia. Further work is required to understand the best way of providing an effective, equitable service for ocular morbidity.

Door to door survey was done. Households were the primary sampling unit. Data analysis has been done using SPSS version 14.0. To test significance chi square test have been used as applicable. Results: 249 (29.4% ever used smoked tobacco. Out of which, 224 (26.4% respondents were current smokers and rest 25 (3% were ever smokers. A total of 311 (36.7% study subjects were found user for non smoked substances and out of these, 204 (24 % were current users and rest 107 (12.7% were ever users. A total of 422 (49.8% subjects were found user (including current and ever user both for any form of the tobacco products (either smoked, non smoked or both. Tobacco use was found significantly associated with socio-economic status, literacy level, parental tobacco use, parental education and male gender. Conclusions: The study documented prevalence and predictors of tobacco use. The study population is at risk of tobacco related morbidity and mortality and needs action targeting the most vulnerable population. Health promotion, health education and behavior change communication as tools, can prove valuable for effective control of tobacco risk behavior.

Summary Background Studies have suggested that the prevalence of dementia is lower in developing than in developed regions. We investigated the prevalence and severity of dementia in sites in low-income and middle-income countries according to two definitions of dementia diagnosis. Methods We undertook one-phase cross-sectional surveys of all residents aged 65 years and older (n=14 960) in 11 sites in seven low-income and middle-income countries (China, India, Cuba, Dominican Republic, Venezuela, Mexico, and Peru). Dementia diagnosis was made according to the culturally and educationally sensitive 10/66 dementia diagnostic algorithm, which had been prevalidated in 25 Latin American, Asian, and African centres; and by computerised application of the dementia criterion from the Diagnostic and Statistical Manual of Mental Disorders (DSM IV). We also compared prevalence of DSM-IV dementia in each of the study sites with that from estimates in European studies. Findings The prevalence of DSM-IV dementia varied widely, from 0·3% (95% CI 0·1–0·5) in rural India to 6·3% (5·0–7·7) in Cuba. After standardisation for age and sex, DSM-IV prevalence in urban Latin American sites was four-fifths of that in Europe (standardised morbidity ratio 80 [95% CI 70–91]), but in China the prevalence was only half (56 [32–91] in rural China), and in India and rural Latin America a quarter or less of the European prevalence (18 [5–34] in rural India). 10/66 dementia prevalence was higher than that of DSM-IV dementia, and more consistent across sites, varying between 5·6% (95% CI 4·2–7·0) in rural China and 11·7% (10·3–13·1) in the Dominican Republic. The validity of the 847 of 1345 cases of 10/66 dementia not confirmed by DSM-IV was supported by high levels of associated disability (mean WHO Disability Assessment Schedule II score 33·7 [SD 28·6]). Interpretation As compared with the 10/66 dementia algorithm, the DSM-IV dementia criterion might underestimate

Objective There are no published prevalence estimates of elimination disorders and their association with disruptive-behavior disorders among children in the Asian region using standardized diagnostic interviews. This study was conducted to determine the prevalence of elimination disorders and its association with disruptive-behavior disorders in a representative sample of children in Seoul, Korea. Methods The diagnosis of enuresis and encopresis was derived from parent-reported data for "enuresis and encopresis," collected using the Diagnostic Interview Schedule for Children, from a representative sample of 6- to 12-year-old children (n=1,645) who participated in the 2005 Seoul Child and Adolescent Mental Health Survey. Prevalence data for attention deficit and disruptive-behavior disorders were collected from the same sample. Results The overall 12-month prevalence of nocturnal enuresis and encopresis was 1.8% and 0.6%, respectively. Enuresis and encopresis prevalence in boys was significantly greater than that in girls. Enuresis and encopresis was most common at 7 to 9 years of age. Enuresis was significantly associated with ADHD (OR 2.6, 95% CI 1.0-6.9) and conduct disorder (CD; OR 4.7, 95% CI 1.0-22.4). Conclusion Enuresis is significantly associated with ADHD and CD, so these conditions must be assessed together during the evaluation of children with enuresis. PMID:24302948

This study aimed to identify the prevalence and predictors of anxiety and depression among family caregivers of patients with cancer in Korea. A national, multicenter, cross-sectional survey was conducted with 897 family caregivers. The Hospital Anxiety and Depression Scale was used to assess anxiety and depression in patient-family caregiver dyads. The prevalence of anxiety in family caregivers was 38.1 %:20.3 % reported mild anxiety, 13.3 % reported moderate anxiety, and 4.6 % reported severe anxiety. The prevalence of depression was 82.2 %:40.4 % reported mild depression, 25.5 % reported moderate depression, and 16.3 % reported severe depression. Family caregivers who were younger, were caring for male patients, or had a low quality of life (QOL) in relation to three of the variables measured in the Korean Caregiver Quality of Life Index-Cancer (CQOLC-K): burden, disturbance, and financial concerns reported increased anxiety. Becoming unemployed during caregiving, being the spouse of a patient and having low QOL in relation to three of the variables measured by the CQOLC-K: burden, disturbance, and positive adaptation were associated with depression among family caregivers. The predictive validity of the selected variables were 0.861 (95 % CI: 0.844-0.892) for anxiety and 0.794 (95 % CI: 0.751-0.828) for depression. Family caregivers of patients with cancer experienced high levels of anxiety and depression. Socio-demographic factors and QOL were predictors of anxiety and depression in family caregivers.

Full Text Available Abstract Background In 2009 the Uterine Bleeding and Pain Women's Research Study (UBP-WRS was conducted interviewing 21,479 women across 8 countries in order to gain patient-based prevalence data on uterine pain and bleeding indications and investigate uterine symptoms and women's treatment experiences. This article shows relevant results of the study for the indication uterine fibroids providing data on self-reported prevalence, symptomatology and management of uterine fibroids. Methods 2,500 women (USA: 4,500 women in each country (Brazil, Canada, France, Germany, Italy, South Korea, the UK, the USA completed an online survey. Women included were in their reproductive age (age group 15-49 years; USA: 18-49 years and had ever experienced menstrual bleedings. Quotas were applied for age, region, level of education and household income of respondents. Variables have been analyzed descriptively and exploratory statistical tests have been performed.

Full Text Available The US Affiliated Pacific region’s childhood obesity prevalence has reached epidemic proportions. To guide program and policy development, a multi-site study was initiated, in collaboration with partners from across the region, to gather comprehensive information on the regional childhood obesity prevalence. The environmental and cultural diversity of the region presented challenges to recruiting for and implementing a shared community-based, public health research program. This paper presents the strategies used to recruit families with young children (n = 5775 for children 2 – 8 years old for obesity-related measurement across eleven jurisdictions in the US Affiliated Pacific Region. Data were generated by site teams that provided summaries of their recruitment strategies and lessons learned. Conducting this large multi-site prevalence study required considerable coordination, time and flexibility. In every location, local staff knowledgeable of the community was hired to lead recruitment, and participant compensation reflected jurisdictional appropriateness (e.g., gift cards, vouchers, or cash. Although recruitment approaches were site-specific, they were predominantly school-based or a combination of school- and community-based. Lessons learned included the importance of organization buy-in; communication, and advance planning; local travel and site peculiarities; and flexibility. Future monitoring of childhood obesity prevalence in the region should consider ways to integrate measurement activities into existing organizational infrastructures for sustainability and cost-effectiveness, while meeting programmatic (e.g. study goals.

Background: We present the prevalence and determinants of glaucoma among subjects 40 years of age and older in Qatar. Materials and Methods: This community-based survey was held in 2009 at 49 randomly selected clusters. Demographic details and history of glaucoma was collected by the nurses. Ophthalmologists evaluated the optic disc and retina using a digital camera housed in a mobile van. Visual field was tested with an automated perimeter, the intraocular pressure with an applanation tonometer and the angle of the anterior chamber by gonioscopy. A panel of glaucoma experts diagnosed subjects with glaucoma. Results: This survey enrolled 3,149 (97.3%) participants. The age- and sex-adjusted prevalence of glaucoma in the population aged 40 years and older was 1.73% (95% confidence intervals [CI] 1.69-1.77). Accordingly, 5,641 individuals in this age group in Qatar would have glaucoma. Chronological age of 60 years and older (Odds ratio [OR] 11.1) and the presence of myopia (OR 1.78) were predictors of glaucoma. Open-angle glaucoma was diagnosed in 44 (65.7%) individuals with glaucoma. In nine (13.4%) and 15 (20.9%) subjects, angle closure glaucoma and other (post-traumatic, pseudoexfoliation) glaucoma were present. Bilateral blindness (vision glaucoma, respectively. Glaucoma was treated in 36 (54%) subjects. Conclusions: The prevalence of glaucoma among citizens of Qatar aged 40 years and older was 1.71%. Glaucoma was associated with the age of 60 years and older and the presence of myopia. PMID:21731325

Evidence is conflicting as to the whether tobacco smoking prevalence is higher in refugee than non-refugee populations. The aim of this study was to compare the prevalence and frequency of tobacco smoking in Palestine refugee and non-refugee adolescent populations in the Middle East. We conducted a cross-sectional analysis of the Global Youth Tobacco Survey (GYTS) conducted in Jordan, Lebanon, Syria, and the West Bank among adolescent Palestine refugees and non-refugees. Age- and sex-adjusted regression models assessed the association between refugee status and current (past-30 day) tobacco use prevalence and frequency. Prevalence estimates for current tobacco smoking were similar between Palestine refugee and non-refugee groups in Jordan (26.7 % vs. 24.0 %), Lebanon (39.4 % vs. 38.5 %), and the West Bank (39.5 % vs. 38.4 %). In Syria, Palestine refugees had nearly twice the odds of current tobacco smoking compared to non-refugees (23.2 % vs. 36.6 %, AOR 1.96, 95 % CI 1.46-2.62). Palestine refugees consumed more cigarettes per month than non-refugees in Lebanon (β 0.57, 95 % CI 0.17-0.97) and Palestine refugees consumed more waterpipe tobacco per month than non-refugees in Syria (β 0.40, 95 % CI 0.19-0.61) and the West Bank (β 0.42, 95 % CI 0.21-0.64). Current tobacco smoking prevalence is in excess of 20 % in both adolescent Palestine refugee and non-refugee populations in Middle Eastern countries, however Palestine refugees may smoke tobacco more frequently than non-refugees. Comparison of simple prevalence estimates may therefore mask important differences in tobacco use patterns within population groups.

Epilepsy is a major health issue in rural areas of developing countries. However, heterogeneity of epilepsy prevalence in different studies precludes assessment of the magnitude of the problem. Using similar protocols, two population-based surveys were conducted 12 years apart (2003 and 2015) in a rural Ecuadorian village (Atahualpa). The only difference was a higher people compliance with interviewers during the second survey. Epilepsy prevalence in the 2003 survey was 13.5 per 1,000 (18/1,332) in villagers aged ≥20 years. This rate increased to 26.8 per 1,000 (41/1,530) in the 2015 survey. Thirty-three persons with epilepsy detected during the second survey lived in the village in 2003; six of them had seizures starting after 2003. Of the remaining 27 cases, 13 (48%) denied their problem during the first survey. Further interview revealed that denial was related to lack of confidence with unacquainted field personnel. Social Desirability Scale-17 scores were lower in those who admitted having epilepsy than in those who denied their condition (p = 0.048). Lack of confidence with interviewers and a social desirability bias account for a sizable proportion of epilepsy denial in the study population, and may explain heterogeneity of epilepsy prevalence reported in studies conducted in poor rural settings.

To examine the prevalence of maternal near-miss (MNM) and its associated risk factors in a community setting in Central Uganda. A cross-sectional research design employing multi-stage sampling collected data from women aged 15-49 years in Rakai, Uganda, who had been pregnant in the 3years preceding the survey, conducted between August 10 and December 31, 2013. Additionally, in-depth interviews were conducted. WHO-based disease and management criteria were used to identify MNM. Binary logistic regression was used to predict MNM risk factors. Content analysis was performed for qualitative data. Survey data were collected from 1557 women and 40 in-depth interviews were conducted. The MNM prevalence was 287.7 per 1000 pregnancies; the majority of MNMs resulted from hemorrhage. Unwanted pregnancies, a history of MNM, primipara, pregnancy danger signs, Banyakore ethnicity, and a partner who had completed primary education only were associated with increased odds of MNM (all Pstudies employing organ-failure MNM-diagnostic criteria. These findings illustrate the need to look beyond mortality statistics when assessing maternal health outcomes. Concerted efforts to increase supervised deliveries, access to emergency obstetric care, and access to contraceptives are warranted.

Full Text Available Abstract Background Musculoskeletal impairment (MSI is an important cause of morbidity and mortality worldwide, especially in developing countries. Prevalence studies for MSI in the developing world have used varying methodologies and are seldom directly comparable. This study aimed to develop a new tool to screen for and diagnose MSI and to pilot test the methodology for a national survey in Rwanda. Methods A 7 question screening tool to identify cases of MSI was developed through literature review and discussions with healthcare professionals. To validate the tool, trained rehabilitation technicians screened 93 previously identified gold standard 'cases' and 86 'non cases'. Sensitivity, specificity and positive predictive value were calculated. A standardised examination protocol was developed to determine the aetiology and diagnosis of MSI for those who fail the screening test. For the national survey in Rwanda, multistage cluster random sampling, with probability proportional to size procedures will be used for selection of a cross-sectional, nationally representative sample of the population. Households to be surveyed will be chosen through compact segment sampling and all individuals within chosen households will be screened. A pilot survey of 680 individuals was conducted using the protocol. Results: The screening tool demonstrated 99% sensitivity and 97% specificity for MSI, and a positive predictive value of 98%. During the pilot study 468 out of 680 eligible subjects (69% were screened. 45 diagnoses were identified in 38 persons who were cases of MSI. The subjects were grouped into categories based on diagnostic subgroups of congenital (1, traumatic (17, infective (2 neurological (6 and other acquired(19. They were also separated into mild (42.1%, moderate (42.1% and severe (15.8% cases, using an operational definition derived from the World Health Organisation's International Classification of Functioning, Disability and Health

Background Patterns of prevalence and work-relatedness of carpal tunnel syndrome (CTS) among workers offer clues about risk factors and targets for prevention. Methods Data from an occupational health supplement to the 2010 National Health Interview Survey were used to estimate the prevalence of self-reported clinician-diagnosed CTS overall and by demographic characteristics. The proportion of these cases self-reported to have been attributed to work by clinicians was also examined overall and by demographic characteristics. In addition, the distribution of industry and occupation (I&O) categories to which work-related cases of CTS were attributed was compared to the distribution of I&O categories of employment among current/recent workers. Results Data were available for 27,157 adults, including 17,524 current/recent workers. The overall lifetime prevalence of clinician-diagnosed CTS among current/recent workers was 6.7%. The 12-month prevalence was 3.1%, representing approximately 4.8 million workers with current CTS; 67.1% of these cases were attributed to work by clinicians, with overrepresentation of certain I&O categories. Conclusions CTS affected almost 5 million U.S. workers in 2010, with prevalence varying by demographic characteristics and I&O. PMID:22495886

Reliable national data on disability which is internationally comparable is needed in Malaysia. This study aims to examine the prevalence of disability among adults in Malaysia and its determinants, particularly the socioeconomic factors and comorbidities. This study was based on the disability module, which is part of the National Health and Morbidity Survey 2015. This survey was implemented using a multi-stage stratified sampling design. A locally validated Washington Group questionnaire was used to collect data on disability. Based on the definition of having at least one domain scored "a lot of difficulty or unable to do at all" or at least "some difficulty" scored in two domains, the prevalence of disability among adults in Malaysia was 11.8% (95% CI: 11.15, 12.53). Logistic regression analysis performed showed that population at risk of having disability in Malaysia were those of older people, ethnic minority, low level of education, single, obese, physically inactive and having mental health problems. Among older people, disability was significantly higher among those with no formal education, having mental health problems and physically inactive. The prevalence of disability among adults in Malaysia is comparable to WHO estimates and most developing countries. Planning for healthcare services should consider at-risk population, particularly older people and those from disadvantaged background to ensure equity healthcare.

Medication errors in oncology may cause severe clinical problems due to low therapeutic indices and high toxicity of chemotherapeutic agents. We aimed to investigate unintentional medication errors and underlying factors during chemotherapy preparation and administration based on a systematic survey conducted to reflect oncology nurses experience. This study was conducted in 18 adult chemotherapy units with volunteer participation of 206 nurses. A survey developed by primary investigators and medication errors (MAEs) defined preventable errors during prescription of medication, ordering, preparation or administration. The survey consisted of 4 parts: demographic features of nurses; workload of chemotherapy units; errors and their estimated monthly number during chemotherapy preparation and administration; and evaluation of the possible factors responsible from ME. The survey was conducted by face to face interview and data analyses were performed with descriptive statistics. Chi-square or Fisher exact tests were used for a comparative analysis of categorical data. Some 83.4% of the 210 nurses reported one or more than one error during chemotherapy preparation and administration. Prescribing or ordering wrong doses by physicians (65.7%) and noncompliance with administration sequences during chemotherapy administration (50.5%) were the most common errors. The most common estimated average monthly error was not following the administration sequence of the chemotherapeutic agents (4.1 times/month, range 1-20). The most important underlying reasons for medication errors were heavy workload (49.7%) and insufficient number of staff (36.5%). Our findings suggest that the probability of medication error is very high during chemotherapy preparation and administration, the most common involving prescribing and ordering errors. Further studies must address the strategies to minimize medication error in chemotherapy receiving patients, determine sufficient protective measures

Background The prevalence of hypertension in emerging nations was scarcely described to date. In Brazil, many population-based surveys evaluated the prevalence in cities throughout the country. However, there is no population-based nationwide study of prevalence of hypertension. In this study, we estimated the prevalence of hypertension for the country and analyzed the trends for the last three decades. Methods Cross-sectional and cohort studies conducted from 1980 to 2010 were independently identified by two reviewers, without language restriction, in the PubMed, Embase, LILACS, and Scielo electronic databases. Unpublished studies were identified in the Brazilian electronic database of theses and in annals of Cardiology congresses and meetings. In total, 40 studies were selected, comprising 122,018 individuals. Results Summary estimates of prevalence by the former WHO criteria (BP≥160/95 mmHg) in the 1980’s and 1990’s were 23.6% (95% CI 17.3–31.4%) and 19.6% (16.4–23.3%) respectively. The prevalence of hypertension by the JNC criteria (BP≥140/90 mmHg) in the 1980’s, 1990’s and 2000’s were 36.1% (95% CI 28.7–44.2%), 32.9% (29.9–36.0%), and 28.7% (26.2–31.4%), respectively (P<0.001). In the 2000’s, the pooled prevalence estimates of self-reported hypertension on telephone inquiries was 20.6% (19.0–22.4%), and of self-reported hypertension in home surveys was 25.2% (23.3–27.2%). Conclusions The prevalence of hypertension in Brazil seems to have diminished 6% in the last three decades, but it still is approximately 30%. Nationwide surveys by self-reporting by telephone interviews underestimate the real prevalence. Rates of blood pressure control decreased in the same period, corresponding currently to only one quarter of individuals with hypertension. PMID:23118964

Full Text Available Context: Work-related musculoskeletal disorders (WRMSD had been previously reported to have a high prevalence among dentists in different parts of the world. Aims: The study aimed to assess the prevalence of self-reported WRMSD among dental professionals in India. Material and Methods: A cross-sectional survey of 646 dentists (response rate of 82.97% was done using self-administered questionnaire which consisted of 27 items based on Nordic questionnaire for screening WRMSDs. Additional items of the questionnaire were added after preliminary content validation from six experienced dentists. Participant socio-demographic characteristics, work-related physical load characteristics, musculoskeletal symptom characteristics were evaluated. Statistical analysis used: All data were analyzed descriptively using percentiles and association between work-related physical load and WRMSD prevalence was done using Chi-square test. Results: All 536 dentists had at least one work-related musculoskeletal symptom in the previous year with an overall period prevalence rate of 100%. The type of symptoms present were pain (99.06%, stiffness (3.35%, fatigue (8.39%, discomfort (12.87%, clicks/sounds (4.1%, and other neurogenic (20.14%. The regions of symptoms were neck (75.74%, wrist/hand (73.13%, lower back (72.01%, shoulder (69.4%, hip (29.85%, upper back (18.65%, ankle (12.31%, and elbow (7.46%. Number of regions affected were two (82.83%, three (51.86%, four, or more (15.11%. Recurrent symptoms were present in 76.11%. Strong association was noted between sustained work postures and symptom regions for pain in WRMSD. Conclusion: The study found an overall one-year period prevalence rate of 100% for WRMSDs among Indian dentists. Measures for improving education and ergonomic evaluations are indicated on a large scale to prevent decline in work performance and incidence of WRMSDs among Indian dentists.

To measure the 12-month prevalence of elder abuse and neglect in community-dwelling older people in Ireland and examine the risk profile of people who experienced mistreatment and that of the perpetrators. Cross-sectional general population survey. Community. People aged 65 years or older living in the community. Information was collected in face-to-face interviews on abuse types, socioeconomic, health, and social support characteristics of the population. Data were examined using descriptive statistics and logistic regression, odds ratios (OR) and 95% confidence intervals (95% CI) are presented. The prevalence of elder abuse and neglect was 2.2% (95% CI: 1.41-2.94) in the previous 12 months. The frequency of mistreatment type was financial 1.3%, psychological 1.2%, physical abuse 0.5%, neglect 0.3%, and sexual abuse 0.05%. In the univariate analysis lower income OR 2.39 (95% CI: 1.01-5.69), impaired physical health OR 3.41 (95% CI: 1.74-6.65), mental health OR 6.33 (95% CI: 3.33-12.0), and poor social support OR 4.91 (95% CI: 2.1-11.5) were associated with a higher risk of mistreatment but only social support and mental health remained independent predictors. Among perpetrators adult children (50%) were most frequently identified. Unemployment (50%) and addiction (20%) were characteristics of this group.

To estimate the current US inflammatory back pain (IBP) prevalence using four published case definitions. Analysis of an IBP data collection instrument specifically designed for the 2009-10 National Health and Nutrition Examination Survey. Subjects were 5103 US adults ages 20-69 with complete data. IBP prevalence as determined by Calin et al criteria, European Spondylarthropathy Study Group (ESSG) criteria, and Berlin criteria 8a and 7b. Age-adjusted US prevalence of IBP by Calin criteria was 5.0% (95% CI 4.2% to 5.8%). Prevalence of IBP was 5.6% (95% CI 4.7% to 6.5%) by ESSG criteria, and 5.8% (95% CI 5.2% to 6.4%) and 6.0% (95% CI 4.9% to 7.1%) by Berlin Criteria 8a and 7b, respectively. IBP prevalence did not differ significantly by age groups or between men and women. IBP prevalence was significantly lower among non-Hispanic black persons compared with non-Hispanic white persons for the Calin and ESSG IBP criteria. For the ESSG and Berlin 7b criteria, non-Hispanic white persons had significantly higher IBP prevalences compared with Mexican Americans. IBP is associated with spondyloarthritis. Awareness of the prevalence of IBP may be useful for planning future epidemiological studies as well as development and validation of diagnostic and classification criteria for specific clinically defined diseases.

Objective To examine the prevalence and trends in overweight and obesity among non-pregnant urban women in Africa over the past two and a half decades. Design Cross-sectional surveys conducted between 1991 and 2014. Settings Demographic and Health Surveys (DHS), repeated cross-sectional data collected in 24 African countries. Participants Adult non-pregnant women aged 15–49 years. The earlier DHS collected anthropometric data on only those women who had children aged 0–5 years. The main analyses were limited to this subgroup. The participants were classified as overweight (25.0–29.9 kg/m2) and obese (≥30.0 kg/m2). Results The prevalence of overweight and obesity among women increased in all the 24 countries. Trends were statistically significant in 17 of the 24 countries in the case of obesity and 13 of the 24 for overweight. In Ghana, overweight almost doubled (p=0.001) while obesity tripled (p=0.001) between 1993 and 2014. Egypt has the highest levels of overweight and obesity at 44% (95% CI 42%, 46.5%) and 39% (95% CI 36.6%, 41.8%), respectively, in 2014 and the trend showed significant increase (p=0.005) from 1995 levels. Also, obesity doubled in Kenya, Benin, Niger, Rwanda, Ivory Coast and Uganda, while tripled in Zambia, Burkina Faso, Mali, Malawi and Tanzania. Ethiopia and Madagascar had the lowest prevalence of both obesity and overweight, with overweight ranging from 7% to 12% and obesity from 1% to 4%. Conclusions Overweight and obesity are increasing among women of reproductive age in urban Africa, with obesity among this age group having more than doubled or tripled in 12 of the 24 countries. There is an urgent need for deliberate policies and interventions to encourage active lifestyles and healthy eating behaviour to curb this trend in urban Africa. PMID:29079606

Report on the results of the safety culture survey conducted in PNRI

An initial safety culture survey was conducted in the Philippine Nuclear Research Institute (PNRI). Sixty six (66) questionnaires as given in A. Adams and A. Williamson's Measurement of Safety Culture in the Nuclear Industry, UNSW, July 1999 were distributed to the different units of PNRI. The number of sets of survey sheets distributed to the different units corresponded to the number of personnel in the unit based on the information obtained from them. Results were obtained from only 33 respondents. ANSTO has been requested to analyze the results of this survey. While waiting for the results from ANSTO, we attempted to proceed with this analysis in order to learn and practice applying the procedure based on the reference cited above.The respondents from the PNRI showed on the overall neutral views towards safety and their work. Although a minority showed positive responses to safety while a small minority showed negative responses. A remarkable result is that all respondents show strong concern over the welfare of the institute, indicating that there is still a good chance for safety culture to be developed positively among the employees given the proper strategies for motivation.

Socioeconomic inequalities in HIV/AIDS prevalence in sub-Saharan African countries: evidence from the Demographic Health Surveys

Science.gov (United States)

2014-01-01

Introduction Extant studies universally document a positive gradient between socioeconomic status (SES) and health. A notable exception is the apparent concentration of HIV/AIDS among wealthier individuals. This paper uses data from the Demographic Health Surveys and AIDS Indicator Surveys to examine socioeconomic inequalities in HIV/AIDS prevalence in 24 sub-Saharan African (SSA) countries, the region that accounts for two-thirds of the global HIV/AIDS burden. Methods The relative and generalized concentration indices (RC and GC) were used to quantify wealth-based socioeconomic inequalities in HIV/AIDS prevalence for the total adult population (aged 15-49), for men and women, and in urban and rural areas in each country. Further, we decomposed the RC and GC indices to identify the determinants of socioeconomic inequalities in HIV/AIDS prevalence in each country. Results Our findings demonstrated that HIV/AIDS was concentrated among higher SES individuals in the majority of SSA countries. Swaziland and Senegal were the only countries in the region where HIV/AIDS was concentrated among individuals living in poorer households. Stratified analyses by gender showed HIV/AIDS was generally concentrated among wealthier men and women. In some countries, including Kenya, Lesotho Uganda, and Zambia, HIV/AIDS was concentrated among the poor in urban areas but among wealthier adults in rural areas. Decomposition analyses indicated that, besides wealth itself (median = 49%, interquartile range [IQR] = 90%), urban residence (median = 54%, IQR = 81%) was the most important factor contributing to the concentration of HIV/AIDS among wealthier participants in SSA countries. Conclusions Further work is needed to understand the mechanisms explaining the concentration of HIV/AIDS among wealthier individuals and urban residents in SSA. Higher prevalence of HIV/AIDS could be indicative of better care and survival among wealthier individuals and urban adults, or reflect

The current study aimed to establish the prevalence of internet gaming disorder (IGD) and its association with demographic characteristics, game genre, game use (time spent on gaming), as well as psychological distress, social phobia and well-being among current online gamers in Singapore. A total of 1251 participants aged 13 to 40 years completed the study which was administered as a web survey. The online questionnaire was designed using QuestionPro, and consisted of 8 sections and 105 questions. The 9-item Internet Gaming Disorder Questionnaire was used to establish the prevalence of IGD in the study. A series of logistic regression models were used to examine the associations between IGD, demographic characteristics and game genre, as well as IGD and psychological distress, social phobia and well-being. The prevalence of IGD established using a cutoff of 5 among those who were current online gamers was 17.7%. Multiple logistic regressions revealed that those meeting criteria of IGD were more likely to be older, reported an earlier age of onset of playing online games, had primary and secondary education versus tertiary education, were currently students versus being currently employed and played massively multiplayer online role-playing games. Distress and social anxiety were higher while satisfaction with life was significantly lower among those who met criteria for IGD than those who did not meet the criteria. The prevalence of IGD and its negative consequences in our sample of current online gamers was significant and point towards the need for further clinical studies and innovative interventions to address the problem.

To understand the prevalence of myopia in primary and middle school students in 6 provinces and the possible influencing factors. Primary and middle school students were selected through multistage cluster sampling in 60 primary and middle schools in 6 provinces in China. The questionnaire survey and eyesight test were conducted among all the students selected according to the national student's physique and health survey protocol. Pearson chi-square test and binary multivariate logistic regression analysis were done to identify the influencing factors for myopia in students. The prevalence of myopia among primary and middle school students surveyed was 55.7%, the gender specific difference was statistically significant (59.7% for girls, 51.9% for boys) (Psleep time, average outdoor activity time during last week, school sport activities in the afternoon, the size of television set at home, time spent on watching TV and playing computer were the influencing factors for myopia. The prevalence of myopia is till high in primary and middle school students. Myopia is associated with both genetic factors and individual eye health related behaviors.

The prevalence of obesity and diabetes mellitus (DM) has increased worldwide. Our objective was to examine trends in the prevalence of overweight, obesity, morbid obesity and DM in Spain from 1987 to 2012. Data were obtained from 8 waves of the national health surveys which are cross-sectional studies conducted in representative samples of the Spanish adult population. Self-reported data of 156,440 adults (≥16 years) from 1987 to 2012 were used. Body mass index (BMI) was calculated from self-reported weight and height. Overweight was defined as a BMI of 25.0 to 29.9kg/m 2 , obesity as a BMI≥30kg/m 2 and morbid obesity as a BMI≥40kg/m 2 . DM was considered present if the participant reported having been diagnosed. Age-adjusted prevalence was adjusted by the direct standardisation method to the 2003 survey population. From 1987 to 2012 age-adjusted prevalence of overweight increased from 34.0% (95% confidence interval [95% CI] 33.2-34.8) to 35.8% (95% CI 35.0-36.6), prevalence of obesity from 8.0% (95% CI 7.5-8.5) to 16.5% (95% CI 15.7-17.1%) and DM prevalence from 4.2% (95% CI 3.9-4.5) to 7.1% (95% CI 6.7-7.4%). Morbid obesity increased from 0.20% (95% CI 0.13-0.27) in 1993 to 0.88% (95% CI 0.70-1.05) in 2012. The growth rate was greater among males. An increasing trend of the prevalence of overweight, obesity, morbid obesity and DM was found in Spain from 1987 to 2012, particularly in males. Copyright © 2016 Elsevier España, S.L.U.

Full Text Available Abstract Background Several studies conducted during the 1990s indicated that childhood allergic diseases were increasing worldwide, but more recent investigations in some Western countries have suggested that the trend is stabilizing or may even be reversing. However, few data are available on the current status of allergic disease prevalence in Chinese children. The aim of the present study was to investigate the prevalence rates of asthma, allergic rhinitis, and eczema in children of three major cities of China, to determine the status of allergic diseases among Chinese children generally, and to evaluate the prevalence of allergic diseases in children of different ages. Methods We conducted a cross-sectional survey between October 2008 and May 2009 in three major cities of China (Beijing, Chongqing, and Guangzhou to evaluate the prevalence rates of childhood allergic diseases including asthma, allergic rhinitis, and eczema, using a questionnaire of the International Study of Asthma and Allergies in Childhood (ISAAC group. A total of 24,290 children aged 0-14 years were interviewed, using a multi-stage sampling method. To acquire data on children aged 3-14 years, we visited schools and kindergartens. To access children too young to attend school or kindergarten, we extended our survey to community health service centers. Each questionnaire was completed by a parent or guardian of a child after an informed consent form was signed. Results Of the 24,290 children in our study, 12,908 (53.14% were males and 11,382 (46.86% females; 10,372 (42.70% were from Beijing, 9,846 (40.53% from Chongqing, and 4,072 (16.77% from Guangzhou. Our survey indicated that in Beijing, Chongqing, and Guangzhou, the prevalence rates of asthma were 3.15%, 7.45%, and 2.09%, respectively; the rates of allergic rhinitis were 14.46%, 20.42%, and 7.83%; and the rates of eczema were 20.64%, 10.02%, and 7.22%. The prevalence of allergic diseases varied with age. Asthma was

To identify the prevalence and impact of heavy menstrual bleeding (HMB) in exercising females where anemia may have a significant effect on training and performance a ‘Female Health Questionnaire’ was designed incorporating a validated diagnostic HMB series, demographics, exercise ability data, training status, anemia, iron supplementation and whether the menstrual cycle had affected training and performance. The survey was conducted in two stages; initially online, advertised via social media, and then repeated via face-to-face interviews with runners registered for the 2015 London Marathon. 789 participants responded to the online survey, and 1073 completed the survey at the marathon. HMB was reported by half of those online (54%), and by more than a third of the marathon runners (36%). Surprisingly, HMB was also prevalent amongst elite athletes (37%). Overall, 32% of exercising females reported a history of anemia, and 50% had previously supplemented with iron. Only a minority (22%) had sought medical advice. HMB is highly prevalent in exercising females, associated with self-reported anemia, increased use of iron supplementation and a perceived negative impact on performance. Further research is needed to investigate the impact of HMB, iron deficiency and anemia in exercising females. PMID:26901873

Using data from the 2010 Baylor Religion Survey (N = 1714), this study investigates the prevalence and religious predictors of healing prayer use among US adults. Indicators include prayed for self (lifetime prevalence = 78.8 %), prayed for others (87.4 %), asked for prayer (54.1 %), laying-on-of-hands (26.1 %), and participated in a prayer group (53.0 %). Each was regressed onto eight religious measures, and then again controlling for sociodemographic variables and health. While all religious measures had net effects on at least one healing prayer indicator, the one consistent predictor was a four-item scale assessing a loving relationship with God. Higher scores were associated with more frequent healing prayer use according to every measure, after controlling for all other religious variables and covariates.

Definitions and classification schemes for suicide attempts vary widely among studies, introducing conceptual, methodological, and clinical problems. We tested the importance of the intent to die criterion by comparing self-injurers with intent to die, suicide attempters, and those who self-injured not to die but to communicate with others, suicide gesturers, using data from the National Comorbidity Survey (n = 5,877). Suicide attempters (prevalence = 2.7%) differed from suicide gesturers (prevalence = 1.9%) and were characterized by male gender, fewer years of education, residence in the southern and western United States; psychiatric diagnoses including depressive, impulsive, and aggressive symptoms; comorbidity; and history of multiple physical and sexual assaults. It is possible and useful to distinguish between self-injurers on the basis of intent to die. Copyright 2006 APA, all rights reserved.

Hypertension is a major contributing factor to the current epidemic of cardiovascular disease in India. Small studies suggest high, and increasing, prevalence especially in urban areas, with poor detection and management, but national data has been lacking. The aim of the current study was to use nationally-representative survey data to examine socio-demographic inequalities in the prevalence, diagnosis and management of hypertension in Indian adults. Using data on self-reported diagnosis and treatment, and blood pressure measurement, collected from 12,198 respondents aged 18+ in the 2007 WHO Study on Global Ageing and Adult Health in India, factors associated with prevalence, diagnosis and treatment of hypertension were investigated. 22% men and 26% women had hypertension; prevalence increased steeply with body mass index (wealth. Adequate blood pressure control was sub-optimal in urban men. Hypertension is very common in India, even among underweight adults and those of lower socioeconomic position. Improved detection is needed to reduce the burden of disease attributable to hypertension. Levels of treatment and control are relatively good, particularly in women, although urban men require more careful attention.

The Tobacco Advertising and Promotion Act (TAPA) was implemented in the United Kingdom in 2003. This study is the first to assess its impact on young people, examining smoking susceptibility (intention to smoke among never smokers) and perceived prevalence across three British cross-sectional samples (aged 11-16) before and after the introduction of the ban. Three in-home surveys (n = 1078, 1121 and 1121) were conducted before (1999 and 2002) and after (2004) the implementation of the TAPA. Significant declines in awareness of tobacco marketing and perceived prevalence occurred across the three waves. Higher levels of awareness and perceived prevalence were associated with increased susceptibility, but direct measures of susceptibility remained stable. The TAPA is protecting young people in United Kingdom from tobacco marketing and reducing perceived prevalence, both of which are linked to susceptibility. The stability of susceptibility across the three waves is probably best explained by both the partial implementation of TAPA at the final survey point and the time such effects take to emerge. The evidence from this and previous studies is, however, that, ultimately, they will appear.

To assess the prevalence of counterfeit anthelminthic medicines in Cambodia, and to determine influential factors. Commonly used anthelminthic medicines were collected from private drug outlets. Medicines were carefully observed including their registration labelling, and their authenticity was investigated with the manufacturers and the Medicines Regulatory Authorities. Samples were analysed by High-Performance Liquid Chromatography at the National Health Product Quality Control Centre, Cambodia. Two hundred and three samples of anthelminthics were collected from 137 drug stores. Domestic products constituted 36.9%. Of 196 samples which were verified for registration, 15.8% were not registered. Of 165 samples successfully investigated for their authenticity, 7 (4.2%) were identified as counterfeit. All of these medicines were purchased in open packs or containers, and most of them were foreign manufactured and/or without registration. The results of our survey urge strict implementation of drug registration and vigilance on the availability of unregistered medicines to combat counterfeit medicines in Cambodia.

To compare ethnic groups for the 12 month prevalence of mental disorders and 12 month treatment contact in Te Rau Hinengaro: The New Zealand Mental Health Survey. Te Rau Hinengaro: The New Zealand Mental Health Survey, undertaken in 2003 and 2004, was a nationally representative face-to-face household survey of 12,992 New Zealand adults aged 16 years and over, including Māori (n = 2595), Pacific people (n = 2236) and a composite Other ethnic group (predominantly European) (n = 8161). Ethnicity was measured using the 2001 census ethnicity question. A fully structured diagnostic interview, the World Health Organization World Mental Health Survey Initiative version of the Composite International Diagnostic Interview (CIDI 3.0) was used to measure disorder. The overall response rate was 73.3%. The 12 month prevalence of any mental disorder was highest in Māori (29.5%; 26.6, 32.4), followed by Pacific people (24.4%; 21.2, 27.6) and Others (19.3%; 18.0, 20.6). Adjustment for age, sex, education and household income reduced differences: Māori (23.9%; 21.3, 26.4), Pacific (19.2%; 16.4, 22.1) and Other (20.3%; 18.9, 21.6). A similar pattern was seen for serious disorder and most individual disorders or disorder groups. After adjustment, Māori were most different from Pacific people and Others for substance use disorder. Both Māori and Pacific people had a higher prevalence of bipolar disorder than Others. Pacific people had the lowest prevalence of major depressive disorder. Among those with disorder, the proportion with a visit for mental health problems to any service was highest among Others (41.1%; 38.1, 44.1), with Māori (32.5%; 28.3, 36.7) intermediate and Pacific (25.4%, 19.4, 31.4) lowest. Adjustment did not alter ethnic differences in service contact. Māori, and to a lesser extent Pacific people, have a higher prevalence of 12 month mental disorders than Others. Differences are reduced after adjusting for sociodemographic correlates. Relative to need

Secondary mapping of lymphatic filariasis in Haiti-definition of transmission foci in low-prevalence settings.

Directory of Open Access Journals (Sweden)

Naomi Drexler

Full Text Available To eliminate Lymphatic filariasis (LF as a public health problem, the World Health Organization (WHO recommends that any area with infection prevalence greater than or equal to 1% (denoted by presence of microfilaremia or antigenemia should receive mass drug administration (MDA of antifilarial drugs for at least five consecutive rounds. Areas of low-antigen prevalence (< 1% are thought to pose little risk for continued transmission of LF. Five low-antigen prevalence communes in Haiti, characterized as part of a national survey, were further assessed for transmission in this study. An initial evaluation of schoolchildren was performed in each commune to identify antigen-positive children who served as index cases for subsequent community surveys conducted among households neighboring the index cases. Global positioning system (GPS coordinates and immunochromatographic tests (ICT for filarial antigenemia were collected on approximately 1,600 persons of all ages in the five communes. The relationship between antigen-positive cases in the community and distance from index cases was evaluated using multivariate regression techniques and analyses of spatial clustering. Community surveys demonstrated higher antigen prevalence in three of the five communes than was observed in the original mapping survey; autochthonous cases were found in the same three communes. Regression techniques identified a significantly increased likelihood of being antigen-positive when living within 20 meters of index cases when controlling for age, gender, and commune. Spatial clustering of antigen-positive cases was observed in some, but not all communes. Our results suggest that localized transmission was present even in low-prevalence settings and suggest that better surveillance methods may be needed to detect microfoci of LF transmission.

In 2010, an estimated 8.2% of U.S. adults had current asthma, and among these persons, 49.1% had had an asthma attack during the past year (1). Workplace exposures can cause asthma in a previously healthy worker or can trigger asthma exacerbations in workers with current asthma* (2). To assess the industry- and occupation-specific prevalence of current asthma, asthma attacks, and asthma-related emergency department (ED) visits among working adults, CDC analyzed 2011-2016 National Health Interview Survey (NHIS) data for participants aged ≥18 years who, at the time of the survey, were employed at some time during the 12 months preceding the interview. During 2011-2016, 6.8% of adults (11 million) employed at any time in the past 12 months had current asthma; among those, 44.7% experienced an asthma attack, and 9.9% had an asthma-related ED visit in the previous year. Current asthma prevalence was highest among workers in the health care and social assistance industry (8.8%) and in health care support occupations (8.8%). The increased prevalence of current asthma, asthma attacks, and asthma-related ED visits in certain industries and occupations might indicate increased risks for these health outcomes associated with workplace exposures. These findings might assist health care and public health professionals in identifying workers in industries and occupations with a high prevalence of current asthma, asthma attacks, and asthma-related ED visits who should be evaluated for possible work-related asthma. Guidelines intended to promote effective management of work-related asthma are available (2,3).

Full Text Available Abstract Background The Asia-Pacific region is home to nearly half of the world’s population. The region has seen a recent rapid increase in the prevalence of obesity, type-2 diabetes and cardiovascular disease. The present systematic review summarizes the recent prevalence and trends of Metabolic Syndrome (MetS among adults in countries of the Asia-Pacific Region. Methods Data on MetS in Asia-Pacific countries were obtained using a stepwise process by searching the online Medline database using MeSH terms ‘Metabolic Syndrome X’ and ‘Epidemiology/EP’. For the purpose of describing prevalence data for the individual countries, studies that were most recent, nationally representative or with the largest sample size were included. When evaluating secular trends in prevalence in a country we only considered studies that evaluated the temporal change in prevalence between similar populations, prospective studies based on the same population or National surveys conducted during different time periods. Results This literature search yielded a total of 757 articles, and five additional article were identified by screening of reference lists. From this total, 18 studies were eligible to be included in the final analysis. Of the 51 Asia-Pacific countries (WHO we only located data for 15. There was wide between country variation in prevalence of MetS. A national survey from Philippines conducted in 2003 revealed the lowest reported prevalence of 11.9% according to NCEP ATP III criteria. In contrast, the highest recorded prevalence in the region (49.0% came from a study conducted in urban Pakistan (Karachchi, 2004. Most studies reported a higher prevalence of MetS in females and urban residents. Data on secular trends were available for China, South Korea and Taiwan. An increase in the prevalence of MetS was observed in all three countries. Conclusion Despite differences in methodology, diagnostic criteria and age of subjects studied, the Asia

Ghana has not conducted a national tuberculin survey or tuberculosis prevalence survey since the establishment of the National Tuberculosis Control Programme. The primary objective of this study was therefore to determine the prevalence of tuberculin skin sensitivity in Ghanaian school children aged 6-10 years in 8 out of 10 regions of Ghana between 2004 and 2006. Tuberculin survey was conducted in 179 primary schools from 21 districts in 8 regions. Schools were purposively selected so as to reflect the proportion of affluent private and free tuition public schools as well as the proportion of small and large schools. Of the 24,778 children registered for the survey, 23,600 (95.2%) were tested of which 21,861 (92.6%) were available for reading. The age distribution showed an increase in numbers of children towards older age: 11% of the children were 6 years and 25%, 10 years. Females were 52.5% and males 47.5%. The proportion of girls was higher in all age groups (range 51.4% to 54.0%, p < 0.001). BCG scar was visible in 89.3% of the children. The percentage of children with a BCG scar differed by district and by age. The percentage of children with a BCG scar decreased with increasing age in all districts, reflecting increasing BCG vaccination coverage in Ghana in the last ten years. The risk of tuberculosis infection was low in the northern savannah zones compared to the southern coastal zones. Using a cut-off of 15 mm, the prevalence of infection ranged from 0.0% to 5.4% and the Annual Risks of Tuberculosis Infection 0.0% to 0.6%. There was an increase in the proportion of infected children after the age of 7 years. Children attending low and middle-class schools had a higher risk of infection than children attending upper-class schools. Tuberculosis infection is still a public health problem in Ghana and to monitor the trend, the survey needs to be repeated at 5 years interval.

Objectives To investigate olfaction in general population, prevalence of olfactory dysfunction and related risk factors. Design Cross-sectional population-based survey, distributing four microencapsulated odorants (rose, banana, musk and gas) and two self-administered questionnaires (odour description; epidemiology/health status). Setting The survey was distributed to general population through a bilingual (Catalan, Spanish) newspaper in Catalonia (Spain), on December 2003. Participants Newspaper readers of all ages and gender; 9348 surveys were analysed from the 10 783 returned. Main outcome measures Characteristics of surveyed population, olfaction by age and gender, smell self-perception and smell impairment risk factors. Terms normosmia, hyposmia and anosmia were used when participants detected, recognised or identified all four, one to three or none of the odours, respectively. Results Survey profile was a 43-year-old woman with medium–high educational level, living in a city. Olfaction was considered normal in 80.6% (detection), 56% (recognition/memory) and 50.7% (identification). Prevalence of smell dysfunction was 19.4% for detection (0.3% anosmia, 19.1% hyposmia), 43.5% for recognition (0.2% anosmia, 43.3% hyposmia) and 48.8% for identification (0.8% anosmia, 48% hyposmia). Olfaction was worse (polfactory self-perception for detection; low educational level, poor self-perception and pregnancy for recognition; and older age, poor self-perception and history of head trauma and loss of smell for identification. Smoking and exposure to noxious substances were mild protective factors for smell recognition. Conclusions Sense of smell in women is better than in men suggesting a learning process during life with deterioration in older ages. Poor self-perception, history of smell loss, head trauma and pregnancy are potential risk factors for olfactory disorders. PMID:23135536

To present nationally representative findings on prevalence, sociodemographic correlates, disability, and comorbidity of narcissistic personality disorder (NPD) among men and women. Face-to-face interviews with 34,653 adults participating in the Wave 2 National Epidemiologic Survey on Alcohol and Related Conditions conducted between 2004 and 2005 in the United States. Prevalence of lifetime NPD was 6.2%, with rates greater for men (7.7%) than for women (4.8%). NPD was significantly more prevalent among black men and women and Hispanic women, younger adults, and separated/divorced/widowed and never married adults. NPD was associated with mental disability among men but not women. High co-occurrence rates of substance use, mood, and anxiety disorders and other personality disorders were observed. With additional comorbidity controlled for, associations with bipolar I disorder, post-traumatic stress disorder, and schizotypal and borderline personality disorders remained significant, but weakened, among men and women. Similar associations were observed between NPD and specific phobia, generalized anxiety disorder, and bipolar II disorder among women and between NPD and alcohol abuse, alcohol dependence, drug dependence, and histrionic and obsessive-compulsive personality disorders among men. Dysthymic disorder was significantly and negatively associated with NPD. NPD is a prevalent personality disorder in the general U.S. population and is associated with considerable disability among men, whose rates exceed those of women. NPD may not be as stable as previously recognized or described in the DSM-IV. The results highlight the need for further research from numerous perspectives to identify the unique and common genetic and environmental factors underlying the disorder-specific associations with NPD observed in this study.

To assess changes from 2007 to 2011 in the prevalence of tobacco use and tobacco-related indicators in Uganda by examining results from the Global Youth Tobacco Survey (GYTS). Both the 2007 (n=2,251) and 2011 (n=2,026) Uganda GYTS were conducted among students in primary seven, secondary one, two, and three. A two-stage cluster sample design was used to generate a representative sample of students for the surveys. Stata 12 software was used to provide weighted prevalence estimates and logistic regression models were developed to examine the relationship between factors that influence tobacco use and current tobacco use. The percentage of students who had ever smoked a cigarette, even just one or two puffs, declined from 15.6% in 2007 to 10.9% in 2011 (p=0.03). From 2007 to 2011, neither the percentage of current use of any tobacco (16.6% to 17.3%, p=0.75), nor the percentage of current (past 30 day) cigarette smoking (5.5% to 4.8%,p=0.59) changed significantly. Following adjustment, having parents [Adjusted Odds Ratio (AOR):1.9, 95% Confidence Interval (CI):1.3-2.8] and friends [AOR 2.5, 95% CI: 1.5-4.0)] who smoke, and having seen tobacco advertisements in print media [AOR 1.8(1.3-2.4)], were associated with greater odds of current tobacco use among students in 2007.Having parents who smoke [AOR;1.8, 95% CI: 1.1-3.0] was associated with greater odds of current tobacco use among students in 2011. From 2007 to 2011, no significant change occurred in the prevalence of current tobacco use or cigarette smoking among youth in Uganda. These findings underscore the importance of implementing effective population-level public health interventions, as outlined in the articles of the World Health Organization's Framework Convention on Tobacco Control, to prevent and reduce the use of tobacco among youth in Uganda.

Recently, a positive association has been reported between hypertension and periodontitis. The authors hypothesized that oral hygiene promotion activities could have an effect on hypertension prevention or the degree of hypertension control. Therefore, this study examines the relationship between oral hygiene behaviors and hypertension using data from a nationally representative survey, the Korea National Health and Nutrition Examination Survey (KNHANES). Using data from the KNHANES (2008 to 2010), 19,560 adults with complete data sets were included. The authors analyzed the relationship of the prevalence and control rate of hypertension and numerous variables, including oral hygiene behavior. As the frequency of toothbrushing increased, the prevalence of hypertension decreased in multivariate analysis after adjusting for various factors, including the presence of periodontitis. In a subgroup analysis, this relationship was also observed in individuals without periodontitis. In particular, systolic blood pressure levels progressively decreased as the frequency of toothbrushing and the number of secondary oral products used increased. The adjusted odds ratio of hypertension prevalence was 1.195 (95% confidence interval 1.033 to 1.383) for individuals who brushed their teeth hardly ever or once daily compared with those who brushed after every meal. Individuals with poor oral hygiene behavior are more likely to have a higher prevalence of hypertension, even before periodontitis is shown. Oral hygiene behavior may be considered an independent risk indicator for hypertension, and maintaining good oral hygiene may help to prevent and control hypertension.

To complete the baseline trachoma map of Sudan by estimating the prevalence of trachoma and associated risk factors in the five Darfur States and Khartoum State. Using a standardized methodology developed for the Global Trachoma Mapping Project, we undertook a cross sectional, community-based survey in each of 32 evaluation units (EUs) covering all accessible districts. We enumerated a total of 84,568 individuals, with 73,489 people (86.9%) examined from 20,242 households in 908 villages. The highest prevalence of trachomatous inflammation - follicular (TF) in children was found in El Fashir district (18.7%), and the lowest in El Malha district (0.0%). Five districts (El Fashir, Zalinji, Azoom, Maleet, and El Koma) were in the three EUs that had TF prevalences above the 10% threshold at which the World Health Organization recommends mass treatment with azithromycin, together with facial clean3liness and environmental improvement interventions, for at least 3 years. The highest trachomatous trichiasis prevalence in adults was found in the EU composed of Forbranga and Habillah (1.2%), and the lowest in the EU composed of As-salam and Belale districts in South Darfur (0.0%). TF in children was independently associated with younger age, unimproved sanitation in the household, having ≥5 children in the household, outside annual maximum temperatures Darfur, but in general the prevalence throughout Darfur and Khartoum was low.

The prevalence of abdominal aortic aneurysm (AAA) and its risk factors are well known in Western countries but few data are available from low- and middle- income countries. We are not aware of systematically collected population- based data on AAA in the African region. We evaluated the prevalence of AAA in a population- based cardiovascular survey conducted in the Republic of Seychelles in 2004 (Indian Ocean, African region). Among the 353 participants aged 50 to 64 years and screened with ultrasound, the prevalence of AAA was 0.3% (95% CI: 0- 0.9) and the prevalence of ectatic dilatations of the abdominal aorta was 1.5% (95% CI: 0.2- 2.8). The prevalence of AAA in the general population seemed lower in Seychelles than in Western countries, despite a high prevalence in Seychelles of risk factors of AAA, such as smoking (in men), high blood pressure and hypercholesterolaemia.

Premature ejaculation (PE) is suspected to be the most prevalent male sexual complaint, and the prevalence of PE is considerably high also in the younger generation. We investigated the PE prevalence based on the Diagnostic and Statistical Manual of Mental Disorders (4th ed text revision; DSM-IV-TR) definition and the risk factors of PE in Korean young men via Internet survey. Subjects (n = 3980) aged from 20 to 59, who performed sexual intercourse more than once a month during the past 6 months were asked to participate in this study. Participants were asked to complete a questionnaire that consisted of questions on general, medical, and sexual history related to ejaculation. A total of 600 subjects were included in this study. PE prevalence was found to be 18.3%. Prevalences were not significantly different across age groups, after excluding subjects with erectile dysfunction (ED). Educational level, marital status and duration, average income, sexual orientation, smoking, alcohol consumption, and circumcision status showed no difference in the PE and non-PE groups. Partners perceived satisfaction rates were 45.0% in the PE group and 63.9% in the non-PE group. Significant differences were found between the PE and non-PE groups in terms of ED, obesity, and depression prevalence. However, multiple logistic regression analysis revealed that the significant risk factors of PE were age and the frequency of conversations with partners about sexual intercourse. This Internet-based study is limited because participants probably represent a selected population of Internet users with non-representative educational and socioeconomic profiles. This study is the first to report the prevalence of both self-reported PE and PE on the basis of the DSM-IV-TR definition in the Korean population. This study demonstrates that PE in Korea is as prevalent as it is in European countries and the United States.

Purpose To evaluate the prevalence and risk factors associated with horizontal strabismus in children and adolescents in South Korea. Methods A total of 5,935 children and adolescents 5–18 years of age who participated in the fourth and fifth Korean National Health and Nutrition Examination Survey (KNHANES IV-V) from July 2008 to December 2011 were evaluated and the prevalence of horizontal strabismus was estimated. Univariate and multivariate logistic regression analyses were conducted to determine the association between demographic, socioeconomic and clinical risk factors and clinically significant exodeviation (≥15 prism diopters [PD]) and esodeviation (≥10 PD). Results Among 5,935 eligible subjects, 84 subjects had clinically significant exodeviation and 13 had clinically significant esodeviation. The overall prevalence of clinically significant horizontal strabismus was 1.6% (95% confidence interval [CI], 1.2–2.1): 1.3% (95% CI, 1.0–1.7) for clinically significant exodeviation and 0.3% (95% CI, 0.1–0.6) for clinically significant esodeviation. Clinically significant exodeviation was associated with amblyopia (adjusted odds ratio [aOR], 6.45; 95% CI, 2.14–19.44), family history of strabismus (aOR, 4.91; 95% CI, 1.71–14.08) and astigmatism ≥1.0 D (aOR, 1.84; 95% CI, 1.13–2.98). Clinically significant esodeviation was associated with hyperopia (aOR, 12.16; 95% CI, 1.31–113.04) and amblyopia (aOR, 4.70; 95% CI, 1.12–19.81). Other demographic, socioeconomic, and clinical variables were not associated with strabismus. Conclusion This study provides data on the prevalence and independent risk factors for clinically significant exodeviation and esodeviation in a representative population of children and adolescents in South Korea.

Published data shows different prevalence trends depending on the region of Europe. The aim of the study was to analyze time trends of the frequency of the respiratory symptoms and allergic diseases in school children (Silesia, Poland) over the last 21 years. We compared the results of four population-based surveys performed in a town of Chorzow in 1993, 2002, 2007 and 2014 in children aged 7-10 years. All four studies had the same study protocol, recruitment (cluster, school-based sampling), questionnaire (WHO respiratory health questionnaire) and the same principal investigator The surveys included 1130 children in 1993, 1421 children in 2002, 1661 children in 2007 and 1698 in 2014. The results covered a 21 year span and showed a statistically significant (p increase in the prevalence of the following physician-diagnosed disorders (1993-2002-2007-2014): asthma (3.4%-4.8%-8.6%-12,6%); allergic rhinitis (4.3%-11.9%-15.9%-13.9%); atopic dermatitis (3.6%-7.9%-12.0%-13.9%); allergic conjunctivitis (4.3%-7.9%-8.3%-7.9%); A simultaneous increasing trend (p increased proportion of treated children (51.3%-51.3%-69.5%-60.7%) and a lower frequency of presenting current symptoms. Our findings are in line with the concept of a real increase in the occurrence of asthma and allergic disease in children. The pattern involves not only physician-diagnosed allergic diseases but also occurrence of symptoms related to respiratory disorders. Diagnosed asthma is better treated and better controlled.

A law banning smoking in enclosed public places was implemented in Italy on January 10, 2005. The aim of this paper is to present a cross-sectional survey on two representative samples of non-smokers of two Italian towns (Florence and Belluno), conducted one year after the introduction of the ban, in order to assess prevalence of second-hand smoke exposure, to record the attitudes towards the ban, and the perception about its compliance in a representative sample of non-smokers. Computer-assisted telephone interviews were carried out in March 2006, from a random sample of households from telephone registries. Respondents were 402 non-smokers from Belluno and 1,073 from Florence. About 12% of Florentines and 7% of Belluno respondents were exposed at home; 39% and 19%, respectively, at work; 10% and 5% in hospitality venues; 20% and 10% in cars. The smoke-free law was almost universally supported (about 98%) even if a smaller proportion of people (about 90%) had the perception that the ban was observed. Second-hand smoke exposure at home and in hospitality premises has dropped to hospitality venues.

The aim of this study was to further investigate the prevalence of Molar Incisor Hypomineralisation (MIH) in the Wellington region, in order to expand on the findings of a recent study. A survey of MIH in a sample of 7-to-10-year-old children attending primary school in Central Wellington, together with data from a similar survey conducted earlier in Wainuiomata. Using the modified Developmental Defects of Enamel index, a single paediatric dentist examined students in the classroom. Any visible occurrences of demarcated opacities, post-eruptive breakdown of enamel and hypoplasia were recorded, along with dental caries experience in primary and permanent teeth. The data were combined with those from the previous study, and statistical analysis was undertaken using the combined data-set. In the Central Wellington study, examinations were conducted on 235 children (participation rate 58.8%, mean age 8.2 years). MIH prevalence was 18.8%. Demarcated opacities and post-eruptive breakdown affected 23.9% and 8.1% (respectively) of the sample. Pooling the data from Central Wellington and Wainuiomata gave a total sample of 756 (mean age 8.2), among which MIH prevalence was 15.7%. Demarcated opacities and post-eruptive breakdown (of any tooth) affected 18.0% and 4.6%, respectively. Hypoplasia of any tooth was observed in 0.7% of the pooled sample. There was no statistically significant association between MIH and either ethnicity or school decile. Although MIH prevalence was 3.9 percentage points higher in the Central Wellington schools than in Wainuiomata, socioeconomic status (measured through school decile) was not significantly associated with MIH. The presence of developmental defects of enamel was associated with greater caries experience in the permanent dentition. In the Wellington schools involved in the study, approximately one in six 7-10-year-old children had MIH. Neither school decile nor ethnicity were modifying factors in the occurrence of MIH.

The prevalence of dentin hypersensitivity is uncertain, yet appropriate diagnosis and treatment of dentin hypersensitivity require accurate knowledge regarding its prevalence. The authors conducted a study to estimate the prevalence of dentin hypersensitivity in general dental practices and to investigate associated risk factors. The authors conducted a cross-sectional survey of 787 adult patients from 37 general dental practices within Northwest Practice-based Research Collaborative in Evidence-based DENTistry (PRECEDENT). Dentin hypersensitivity was diagnosed by means of participants' responses to a question regarding pain in their teeth and gingivae, and practitioner-investigators conducted a clinical examination to rule out alternative causes of pain. Participants recorded their pain level on a visual analog scale and the Seattle Scales in response to a one-second air blast. The authors used generalized estimating equation log-linear models to estimate the prevalence and the prevalence ratios. The prevalence of dentin hypersensitivity was 12.3 percent; patients with hypersensitivity had, on average, 3.5 hypersensitive teeth. The prevalence of dentin hypersensitivity was higher among 18- to 44-year olds than among participants 65 years or older; it also was higher in women than in men, in participants with gingival recession than in those without gingival recession and in participants who underwent at-home tooth whitening than in those who did not. Hypersensitivity was not associated with obvious occlusal trauma, noncarious cervical lesions or aggressive toothbrushing habits. One in eight participants from general practices had dentin hypersensitivity, which was a chronic condition causing intermittent, low-level pain. Patients with hypersensitivity were more likely to be younger, to be female and to have a high prevalence of gingival recession and at-home tooth whitening. Given dentin hypersensitivity's prevalence, clinicians should diagnose it only after

Iftikhar Alam

2014-08-01

Full Text Available Fresh, bias-free and valid data collected using different survey modes is considered an essential requirement for smooth functioning and evolution of an organization. Surveys play a major role in making in-time correct decisions and generating reports. The aim of this study is to compare and investigate state-of-the-art in different survey modes including print, email, online, mobile and SMS-based surveys. Results indicated that existing methods are neither complete nor sufficient to fulfil the overall requirements of an organization which primarily rely on surveys. Also, it shows that SMS is a dominant method for data collection due to its pervasiveness. However, existing SMS-based data collection has limitations like limited number of characters per SMS, single question per SMS and lake of multimedia support. Recent trends in data collection emphasis on data collection applications for smart phones. However, in developing countries low-end mobile devices are still extensively used which makes the data collection difficult from man in the street. The paper conclude that existing survey modes and methods should be improved to get maximum responses quickly in low cost manner. The study has contributed to the area of surveying and data collection by analysing different factors such as cost, time and response rate. The results of this study can help practitioners in creating a more successful surveying method for data collection that can be effectively used for low budget projects in developed as well as developing countries.

Full Text Available Objective. To determine the prevalence and trend of diabetes, related glycemic control, and influential socioeconomic (SES factors in the Thai population aged ≥20 years during 2004–2014. Methods. Data from the Thai National Health Examination Survey 2004, 2009, and 2014 were used. Age-adjusted prevalence was calculated, and the associations of education levels with prevalence of diabetes and glycemic control were examined using logistic regression. Results. Age-adjusted prevalence of diabetes increased from 7.7% in 2004 to 7.8% in 2009 and 9.9% in 2014 (8.9% among men and 10.8% among women. Proportions of undiagnosed diabetes were slightly decreased but remained high in 2014 (51.2% for men and 41.3% for women. Diabetes prevalence was higher among those with primary education in both sexes; however, undiagnosed diabetes was higher among women with secondary and university educations. The percentages of those treated and controlled slightly improved among men (45.9% but not among women (36.4%. Unmet glycemic control was also higher among women with secondary education levels and among men with university-level educations. Conclusions. Epidemic diabetes continues to grow in the Thai population, particularly in individuals with lower educational attainment. Measures to detect new cases and strengthen glycemic control should be scaled up.

Waterpipe tobacco smoking is highly prevalent among young people in some settings. There is an absence of nationally representative prevalence studies of waterpipe tobacco use and dual use with other tobacco products in young people. We conducted a secondary analysis of the Global Youth Tobacco Survey, a nationally representative cross-sectional study of students aged 13-15 years. Of 180 participating countries, 25 included optional waterpipe tobacco smoking questions: 15 Eastern Mediterranean and 10 Eastern European countries. We calculated the prevalence of current (past 30-day) waterpipe tobacco use, including dual waterpipe and other tobacco use, and used logistic regression models to identify sociodemographic correlates of waterpipe tobacco smoking. Individual country results were combined in a random effects meta-analysis. Waterpipe tobacco smoking prevalence was highest in Lebanon (36.9%), the West Bank (32.7%) and parts of Eastern Europe (Latvia 22.7%, the Czech Republic 22.1%, Estonia 21.9%). These countries also recorded greater than 10% prevalence of dual waterpipe and cigarette use. In a meta-analysis, higher odds of waterpipe tobacco smoking were found among males (Adjusted odds ratio [AOR] = 1.37, 95% confidence interval [CI] = 1.18% to 1.59%), cigarette users (AOR = 6.95, 95% CI = 5.74% to 8.42%), those whose parents (AOR = 1.54, 95% CI = 1.31% to 1.82%) or peers smoked (AOR = 3.53, 95% CI = 2.97% to 4.20%) and those whose parents had higher educational attainment (Father, AOR = 1.47, 95% CI = 1.14% to 1.89%; Mother, AOR = 1.62, 95% CI = 1.07% to 2.46%).

Robotic-assisted laparoscopy (RAL) is being widely accepted in the field of urology as a replacement for conventional laparoscopy (CL). Nevertheless, the process of its integration in clinical routines has been rather spontaneous. To determine the prevalence of robotic systems (RS) in urological clinics in Germany, Austria and Switzerland, the acceptance of RAL among urologists as a replacement for CL and its current use for 25 different urological indications. To elucidate the practice patterns of RAL, a survey at hospitals in Germany, Austria and Switzerland was conducted. All surgically active urology departments in Germany (303), Austria (37) and Switzerland (84) received a questionnaire with questions related to the one-year period prior to the survey. The response rate was 63%. Among the participants, 43% were universities, 45% were tertiary care centres, and 8% were secondary care hospitals. A total of 60 RS (Germany 35, Austria 8, Switzerland 17) were available, and the majority (68%) were operated under public ownership. The perception of RAL and the anticipated superiority of RAL significantly differed between robotic and non-robotic surgeons. For only two urologic indications were more than 50% of the procedures performed using RAL: pyeloplasty (58%) and transperitoneal radical prostatectomy (75%). On average, 35% of robotic surgeons and only 14% of non-robotic surgeons anticipated RAL superiority in some of the 25 indications. This survey provides a detailed insight into RAL implementation in Germany, Austria and Switzerland. RAL is currently limited to a few urological indications with a small number of high-volume robotic centres. These results might suggest that a saturation of clinics using RS has been achieved but that the existing robotic capacities are being utilized ineffectively. The possible reasons for this finding are discussed, and certain strategies to solve these problems are offered. © 2015 S. Karger AG, Basel.

Full Text Available Sexually transmitted infections (STIs and bacterial vaginosis (BV are associated with increased transmission of HIV, and poor reproductive and sexual health. The burden of STIs/BV among young people is unknown in many high HIV prevalence settings. We conducted an acceptability, feasibility, and prevalence study of home-based sampling for STIs/BV among young men and women aged 15-24 years old in a health and demographic surveillance site (HDSS in rural KwaZulu-Natal, South Africa.A total of 1,342 young people, stratified by age (15-19 and 20-24 years and sex were selected from the HDSS sampling frame; 1,171/1,342 (87% individuals had ≥1 attempted home visit between 4 October 2016 and 31 January 2017, of whom 790 (67% were successfully contacted. Among the 645 who were contacted and eligible, 447 (69% enrolled. Consenting/assenting participants were interviewed, and blood, self-collected urine (men, and vaginal swabs (women were tested for herpes simplex virus type 2 (HSV-2, chlamydia, gonorrhoea, syphilis, trichomoniasis, and BV. Both men and women reported that sample collection was easy. Participants disagreed that sampling was painful; more than half of the participants disagreed that they felt anxious or embarrassed. The weighted prevalence of STIs/BV among men and women, respectively, was 5.3% and 11.2% for chlamydia, 1.5% and 1.8% for gonorrhoea, 0% and 0.4% for active syphilis, 0.6% and 4.6% for trichomoniasis, 16.8% and 28.7% for HSV-2, and 42.1% for BV (women only. Of the women with ≥1 curable STI, 75% reported no symptoms. Factors associated with STIs/BV included having older age, being female, and not being in school or working. Among those who participated in the 2016 HIV serosurvey, the prevalence of HIV was 5.6% among men and 19% among women. Feasibility was impacted by the short study duration and the difficulty finding men at home.A high prevalence of STIs/BV was found in this rural setting with high HIV prevalence in South

BACKGROUND: Very little is known about the prevalence of acquired brain injury (ABI) in Ireland. ABI prevalence has previously been obtained from Belgian general practitioners using a postal survey. We attempted to ascertain the prevalence of ABI in County Mayo through a postal survey of all general practitioners in the county.The specific objectives of this project were to:1. identify whether general practitioners are a. aware of patients with ABI aged 18-65 in their practices b. able to provide prevalence data on ABI in patients aged 18-65 c. able to provide data on age, gender and patient diagnosis 2. analyse prevalence of ABI from any available data from general practitioners. METHODS: A pilot postal survey was performed initially in order to assess the feasibility of the study. It was established that general practitioners did have the necessary information required to complete the questionnaire. A main postal survey was then undertaken. A postal questionnaire was administered to all general practices in County Mayo in the west of Ireland (n = 59). The response rate was 32.2% (n = 19). RESULTS: General practitioners who replied on behalf of their practice could provide data on patient age, gender and diagnosis. In the nineteen practices, there were 57 patients with ABI. The age-specific prevalence of ABI in the area surveyed was estimated at 183.7 per 100,000. The mean patient population per practice was 2,833 (SD = 950). There were found to be significantly more patients with ABI in rural areas than urban areas (p = 0.006). There were also significant differences in the ages of patients in the different ABI categories. Patients whose ABI was of traumatic origin were significantly younger than those patients with ABI of haemorrhagic origin (p = 0.002). CONCLUSION: Although this is a small-scale study, we have ascertained that general practitioners do have data on patients with ABI. Also, some prevalence data now exist where none was available before. These can

In 2011-12, the European Centre for Disease Prevention and Control (ECDC) held the first Europe-wide point-prevalence survey of health-care-associated infections in acute care hospitals. We analysed paediatric data from this survey, aiming to calculate the prevalence and type of health-care-associated infections in children and adolescents in Europe and to determine risk factors for infection in this population. Point-prevalence surveys took place from May, 2011, to November, 2012, in 1149 hospitals in EU Member States, Iceland, Norway, and Croatia. Patients present on the ward at 0800 h on the day of the survey and who were not discharged at the time of the survey were included. Data were collected by locally trained health-care workers according to patient-based or unit-based protocols. We extracted data from the ECDC database for all paediatric patients (age 0-18 years). We report adjusted prevalence for health-care-associated infections by clustering at the hospital and country level. We also calculated risk factors for development of health-care-associated infections with use of a generalised linear mixed-effects model. We analysed data for 17 273 children and adolescents from 29 countries. 770 health-care-associated infections were reported in 726 children and adolescents, corresponding to a prevalence of 4·2% (95% CI 3·7-4·8). Bloodstream infections were the most common type of infection (343 [45%] infections), followed by lower respiratory tract infections (171 [22%]), gastrointestinal infections (64 [8%]), eye, ear, nose, and throat infections (55 [7%]), urinary tract infections (37 [5%]), and surgical-site infections (34 [4%]). The prevalence of infections was highest in paediatric intensive care units (15·5%, 95% CI 11·6-20·3) and neonatal intensive care units (10·7%, 9·0-12·7). Independent risk factors for infection were age younger than 12 months, fatal disease (via ultimately and rapidly fatal McCabe scores), prolonged length of stay, and

Full Text Available Chagas disease (CD affects over six million people and is a leading cause of cardiomyopathy in Latin America. Given recent migration trends, there is a large population at risk in the United States (US. Early stage cardiac involvement from CD usually presents with conduction abnormalities on electrocardiogram (ECG including right bundle branch block (RBBB, left anterior or posterior fascicular block (LAFB or LPFB, respectively, and rarely, left bundle branch block (LBBB. Identification of disease at this stage may lead to early treatment and potentially delay the progression to impaired systolic function. All ECGs performed in a Los Angeles County hospital and clinic system were screened for the presence of RBBB, LAFB, LPFB, or LBBB. Patients were contacted and enrolled in the study if they had previously resided in Latin America for at least 12 months and had no history of cardiac disease. Enzyme-linked immunosorbent assay (ELISA and immunofluorescence assay (IFA tests were utilized to screen for Trypanosoma cruzi seropositivity. A total of 327 consecutive patients were screened for CD from January 2007 to December 2010. The mean age was 46.3 years and the mean length of stay in the US was 21.2 years. Conduction abnormalities were as follows: RBBB 40.4%, LAFB 40.1%, LPFB 2.8%, LBBB 5.5%, RBBB and LAFB 8.6%, and RBBB and LPFB 2.8%. Seventeen patients were positive by both ELISA and IFA (5.2%. The highest prevalence rate was among those with RBBB and LAFB (17.9%. There is a significant prevalence of CD in Latin American immigrants residing in Los Angeles with conduction abnormalities on ECG. Clinicians should consider evaluating all Latin American immigrant patients with unexplained conduction disease for CD.

Visual impairment has become a global challenge, especially for developing countries. This study aims to estimate the prevalence, causes and social factors of visual impairment among Chinese adults. Data were from a nationally representative population-based cross-sectional study. The study population were 1,909,199 non-institutionalized adults aged 18 years and older in mainland China. In the survey, low vision and blindness were checked by ophthalmologists according to the WHO best-corrected visual acuity (BCVA) criteria. Population weighted numbers and prevalence of low vision and blindness with 95% confidence intervals (CIs) were estimated where appropriate. Multivariable logistic regression analysis was used to identify the social factors of visual impairment. The weighted prevalence of visual impairment was 17.17 (95% CI, 16.84-17.50) per 1000 Chinese adults aged 18 years and older. Cataract (57.35%), disorders of choroid and retina (9.80%), and disorders of cornea (6.49%) contributed more than 70 percent to the visual impairment in Chinese adults. Older age groups, young or middle-aged male adults, female elders, illiterate, rural dwellers, non-eastern residents, singles, unemployment, and from family with lower income were associated with visual impairment. More efforts are warranted to enhance treatment and rehabilitation among people with eye disorders to prevent visual impairment.

Full Text Available Abstract Background Rapid socioeconomic development resulting in changing lifestyles and life expectancy appears to be accompanied by an increasing prevalence of type 2 diabetes. Genetic predisposition related to ethnicity is a major determinant of diabetes risk. This study investigates the prevalences of diabetes and prediabetes in different ethnic populations residing in the Mudanjiang area located in the northeast of China. Methods A cross-sectional survey was carried out among Han, Manchu and Korean Chinese aged 20 years or older. Diabetes and prediabetes were diagnosed using standard oral glucose tolerance tests. Results The prevalence of diabetes in Manchu (8.39% and Korean Chinese (9.42% was significantly lower than that in Han (12.10%. The prevalence of prediabetes was 18.96%, 19.36% and 20.47% in Han, Manchu and Korean populations, respectively. Korean Chinese had a lower prevalence of isolated impaired fasting glucose and higher prevalence of isolated impaired glucose tolerance than the other two ethnic groups. Most patients with diabetes, especially ethnic minority patients, were undiagnosed. A multiple logistic regression analysis showed that age, family history of diabetes, control of diet, self-monitoring of weight, central obesity, increased heart rate, hypertension, elevated plasma triglyceride level, elevated plasma low-density lipoprotein cholesterol, and Han ethnicity were significantly associated with an increased risk of diabetes. Further, Manchu Chinese were found to have the lowest risk of diabetes. Conclusions Our study indicates that diabetes is a major public health problem in the Mudanjiang area of China. Ethnicity plays a role in the different prevalences of diabetes and prediabetes among the three ethnic groups. Diabetes is less prevalent among Manchu Chinese compared with Han and Korean Chinese.

Full Text Available The information on the changes of prevalence of MetS in China is limited. Our objective was to assess a 10-year's change of the prevalence of MetS in a Chinese elderly population between 2001 and 2010.We conducted two cross-sectional surveys in a representative sample of elderly population aged 60 to 95 years in Beijing in 2001 and 2010 respectively. MetS was defined according to the 2009 harmonizing definition.A total of 2,334 participants (943 male, 1,391 female in 2001 and 2,102 participants (848 male, 1,254 female in 2010 completed the survey. The prevalence of MetS was 50.4% (95%CI: 48.4%-52.4% in 2001 and 58.1% (95%CI: 56.0%-60.2% in 2010. The absolute change of prevalence of MetS was 7.7% over the 10-year's period (p<0.001. The syndrome was more common in female than male in both survey years. Among the five components, hypertriglyceridemia and low HDL-C had increased most, with an increase of 14.8% (from 29.4% to 44.2% and 9.9% (from 28.3% to 38.2% respectively. The adjusted ORs of MetS for CHD, stroke and CVD were 1.67(95%CI: 1.39-1.99, 1.50(95%CI: 1.19-1.88 and 1.70(95%CI: 1.43-2.01 respectively in 2001, and were 1.74(95%CI: 1.40-2.17, 1.25(95%CI: 0.95-1.63 and 1.52(95%CI: 1.25-1.86 respectively in 2010.The prevalence of MetS is high and increasing rapidly in this Chinese elderly population. Participants with Mets and its individual components are at significantly elevated ORs for CVD. Urgent public health actions are needed to control MetS and its components, especially for dislipidemia.

National narcolepsy survey

LENUS (Irish Health Repository)

Doherty, L.

2010-04-01

Narcolepsy is characterised by excessive daytime sleepiness and cataplexy and has a prevalence of 25 per 100,000. We suspect this is higher than presently seen in the Republic of Ireland. We aimed to calculate the Irish prevalence of Narcolepsy and to examine current management practices. We conducted an online survey of respiratory physicians, neurologists, paediatric neurologists, and psychiatrists with an interest in sleep disorders (73% response rate). Of this group, a total of 16 physicians managed 180 patients prior to January 2009. A clinical diagnosis alone was reached in 67 (41%) patients, the remainder by polysomnography or multiple sleep latency testing. No patients were diagnosed by cerebro-spinal fluid analysis of hypocretin levels. While 70 (42%) patients received modafanil, only 7 (4%) were treated with sodium oxybate. Even allowing for missing data it is apparent that Narcolepsy is hugely under-diagnosed in Ireland, however, current practises adhere with new international guidelines.

The Guidelines for the implementation of Article 11 of the World Health Organization (WHO) Framework Convention on Tobacco Control (FCTC) require that cigarette health warning labels should include pictures and take up 50% or more of the principal display area. This study examined how the association between large pictorial warnings, those covering ≥50% of the front and back of the package, and the prevalence of cigarette smoking varies by educational attainment. We pooled individual-level tobacco use data from the Global Adult Tobacco Survey (GATS) in 18 countries between 2008 and 2013 and linked them with warning label requirements during the same period from the MPOWER database and reports regarding warnings. The respondents' self-reported exposure to warnings was examined according to education. Logistic regressions were further employed to analyze education-specific associations between large pictorial warnings and smoking prevalence, and whether such association differed by education was examined using an interaction test. At the time of the survey, eight out of 18 countries had imposed graphic warning labels that covered ≥50% of the package. These warnings were associated with a 10.0% (OR = 0.89; 95% CI: 0.81, 0.97; p ≤ 0.01) lower cigarette smoking prevalence among adults with less than a secondary education or no formal education, but not among respondents with at least a secondary education. Less educated respondents were also less likely to be exposed to warnings in all 18 countries. The association between strong warnings and lower smoking prevalence among less educated respondents could be greater if their exposure to warnings increases. Prominent pictorial warning labels can potentially reduce health disparities resulting from smoking across different education levels.

Full Text Available Abstract Background College students are vulnerable to tobacco addiction. Tobacco industries often target college students for marketing. Studies about prevalence of tobacco use and its correlates among college students in Nepal are lacking. Methods A cross-sectional survey was carried out in two cities of western Nepal during January-March, 2007. A pre-tested, anonymous, self-administered questionnaire (in Nepali adapted from Global Youth Tobacco Survey (GYTS and a World Bank study was administered to a representative sample of 1600 students selected from 13 junior colleges by two-stage stratified random sampling. Results Overall prevalence of 'ever users' of tobacco products was 13.9%. Prevalence among boys and girls was 20.5% and 2.9% respectively. Prevalence of 'current users' was 10.2% (cigarette smoking: 9.4%, smokeless products: 6.5%, and both forms: 5.7%. Median age at initiation of cigarette smoking and chewable tobacco was 16 and 15 years respectively. Among the current cigarette smokers, 58.7% (88/150 were smoking at least one cigarette per day. Most (67.8% 'Current users' purchased tobacco products by themselves from stores or got them from friends. Most of them (66.7% smoked in tea stalls or restaurants followed by other public places (13.2%. The average daily expenditure was 20 Nepalese rupees (~0.3 USD and most (59% students reported of having adequate money to buy tobacco products. Majority (82% of the students were exposed to tobacco advertisements through magazines/newspapers, and advertising hoardings during a period of 30 days prior to survey. The correlates of tobacco use were: age, gender, household asset score and knowledge about health risks, family members, teachers and friends using tobacco products, and purchasing tobacco products for family members. Conclusion School/college-based interventions like counseling to promote cessation among current users and tobacco education to prevent initiation are necessary

Clinical inference suggests the prevalence of non-celiac gluten sensitivity is substantially higher than that of celiac disease in the USA. Unfortunately, there are currently no data supporting these claims. The authors analyzed nationally representative data to estimate the prevalence of adherence to a gluten-free diet among participants without celiac disease and also to characterize the demographics and general health status of these participants. The Continuous National Health and Nutrition Examination Survey (NHANES) 2009-2010 enrolled 7762 individuals representing the civilian, non-institutionalized, US population free of celiac disease. Participants responded to interviewer administered questionnaires regarding current adherence to a gluten-free diet. Prevalence estimates were computed using SAS survey procedures. There were 49 individuals who reported current adherence to a gluten-free diet reflecting a weighted prevalence of 0.548% (95% CI 0.206-0.889). The prevalence of a gluten-free diet was higher in females (0.58%) than males (0.37%), although this was not statistically significant (p = 0.34). Participants reporting a gluten-free diet were older (46.6 vs. 40.5 years, p = 0.005), had higher high-density lipoprotein, lower iron and lower body mass index. The estimated national prevalence of non-celiac gluten sensitivity is 0.548%, approximately half that of celiac disease. Future studies are merited in order to better understand the population burden of non-celiac gluten sensitivity.

Although the prevalence of oral clefts in China is among the highest worldwide, little is known about the prevalence of speech disability associated with cleft palate in Chinese children. The data for this study were collected from the Second China National Sample Survey on Disability, and identification of speech disability associated with cleft palate was based on consensus manuals. Logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs). A weighted number of 112,070 disabled children affected by cleft palate were identified, yielding a prevalence of 3.45 per 10,000 children (95% CI: 3.19–3.71). A history of speech disability in the mother (OR = 20.266, 95% CI 5.788–70.959, p cleft palate in the offspring. Our results showed that maternal speech disability, older paternal child-bearing age, and lower levels of parental education were independent risk factors for speech disability associated with cleft palate for children in China. These findings may have important implications for health disparities and prevention. PMID:27886104
