ABSTRACT OBJECTIVE To estimate the prevalences of tobacco use, tobacco experimentation, and frequent smoking among Brazilian adolescents. METHODS We evaluated participants of the cross-sectional, nation-wide, school-based Study of Cardiovascular Risks in Adolescents (ERICA), which included 12- to 17-year-old adolescents from municipalities of over 100 thousand inhabitants. The study sample had a clustered, stratified design and was representative of the whole country, its geographical regions, and all 27 state capitals. The information was obtained with self-administered questionnaires. Tobacco experimentation was defined as having tried cigarettes at least once in life. Adolescents who had smoked on at least one day over the previous 30 days were considered current cigarette smokers. Having smoked cigarettes for at least seven consecutive days was an indicator for regular consumption of tobacco. Considering the complex sampling design, prevalences and 95% confidence intervals were estimated according to sociodemographic and socio-environmental characteristics. RESULTS We evaluated 74,589 adolescents. Among these, 18.5% (95%CI 17.7-19.4) had smoked at least once in life, 5.7% (95%CI 5.3-6.2) smoked at the time of the research, and 2.5% (95%CI 2.2-2.8) smoked often. Adolescents aged 15 to 17 years had higher prevalences for all indicators than those aged 12 to 14 years. The prevalences did not differ significantly between sexes. The highest prevalences were found in the South region and the lowest ones, in the Northeast region. Regardless of sex, the prevalences were found to be higher for adolescents who had had paid jobs, who lived with only one parent, and who reported having been in contact with smokers either inside or outside their homes. Female public school adolescents were found to smoke more than the ones from private schools. CONCLUSIONS Tobacco use among adolescents is still a challenge.

The median maxillary labial frenum (MMLF) is a normal anatomic structure with inherent morphologic variations. This study sought to evaluate the prevalence of those variations in a diverse ethnic population and to educate practitioners about the prevalence of MMLF variations to prevent unnecessary biopsies. This study included adult, adolescent, and child patients at the Louisiana State University Health Science Center School of Dentistry. Among the 284 subjects examined, frenum normale was the most common frenum classification, followed by frenum with nodule and frenum with appendix. Most nodules were found in the intermediate third of the MMLF, while appendices were mainly found in the labial third. The prevalence of an appendix was significantly higher (P variations of the MMLF are inherent and do not represent a pathologic condition, nor do they require biopsy for diagnostic purposes.

Full Text Available Introduction: Body dysmorphic disorder is one of the common disorders in which adolescents give excessive attention to their appearances. In fact, it may causes disruptions in adolescents' individual and social life. Therefore, this study aimed to investigate the prevalence of body dysmorphic disorder in female adolescents of Yazd. Method: In this cross-sectional study, the population consisted of all high school female students of Yazd (N= 10737 in 2012-2013, among which 371 students were selected as the study sample by using Cochran formula and cluster sampling method. Moreover, the participants completed a series of demographic questions as well as the questionnaire of Yale-Brown Obsessive Compulsive Scale-Body Dysmorphic Disorder (Y-BOCS-BDD. Results: The findings revealed that 41% of sample were reported to have unusual concern about appearance and body shape in range of low to very severe. As a matter of fact, most of them experienced moderate severity and 7.1% showed severe body dysmorphic disorder that required immediate psychological intervention. The prevalence in female adolescents was estimated as 7.1% and most prevalent age of suffering was 17. Conclusion: In this research, it was endeavored to provide a more realistic image of body dysmorphic disorder in Yazd adolescents by utilizing a precise methodology. Considering the high prevalence of this disorder in female adolescents and its adverse consequences, some programs are recommended to be applied for diagnosis and early treatment of body dysmorphic disorder to promote adolescents mental health.

The current study determined the prevalence of severe fatigue in adolescent and young adult (AYA) cancer patients (aged 18-35 years at diagnosis) consulting a multidisciplinary AYA team in comparison with gender- and age-matched population-based controls. In addition, impact of severe fatigue on quality of life and correlates of fatigue severity were examined. AYAs with cancer (n = 83) completed questionnaires including the Checklist Individual Strength (CIS-fatigue), Quality of Life (QoL)-Cancer Survivor, Hospital Anxiety and Depression Scale (reflecting psychological distress), and the Cancer Worry Scale (reflecting fear of cancer recurrence or progression). The vast majority of participants had been treated with chemotherapy (87%) and had no active treatment at the time of participation (73.5%). Prevalence of severe fatigue (CIS-fatigue score ≥35) in AYAs with cancer (48%, n = 40/83) was significantly higher in comparison with matched population-based controls (20%, n = 49/249; p fatigued AYAs with cancer reported lower QoL compared to non-severely fatigued AYAs with cancer (p fatigue severity (p fatigue based on a validated cut-off score was highly prevalent in this group of AYAs with cancer. QoL is significantly affected by severe fatigue, stressing the importance of detection and management of this symptom in those patients affected by a life-changing diagnosis of cancer in late adolescence or young adulthood.

Full Text Available Objective. Report prevalence of functioning difficulties and disabilities among Mexican adolescent women 15-17 years old and identify differences in characteristics of those with and without a functioning difficulty or disability Materials and methods. Using data from the National Survey of Boys, Girls and Women in Mexico 2015 we estimated prevalence of functioning difficulties and disability and used chi square tests for independence and logistic regression to explore associations between this condition and various characteristics. Results. Of Mexican adolescent women 15-17 years old, 11.1% had a functioning difficulty or disability. The group of domains of functioning difficulty and disability with by far the highest prevalence was socio-emotional and behavioral functioning difficulties or disability with 8.6%. Being employed, rural residence and self-reported depression symptoms were associated with having functioning difficulties or disability. Conclusions. This survey constitutes an important initial step in collecting data on functioning difficulty and disability in Mexico although larger samples should be studied.

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.

Full Text Available Narrative reviews of paediatric NAFLD quote prevalences in the general population that range from 9% to 37%; however, no systematic review of the prevalence of NAFLD in children/adolescents has been conducted. We aimed to estimate prevalence of non-alcoholic fatty liver disease (NAFLD in young people and to determine whether this varies by BMI category, gender, age, diagnostic method, geographical region and study sample size.We conducted a systematic review and meta-analysis of all studies reporting a prevalence of NAFLD based on any diagnostic method in participants 1-19 years old, regardless of whether assessing NAFLD prevalence was the main aim of the study.The pooled mean prevalence of NAFLD in children from general population studies was 7.6% (95%CI: 5.5% to 10.3% and 34.2% (95% CI: 27.8% to 41.2% in studies based on child obesity clinics. In both populations there was marked heterogeneity between studies (I2 = 98%. There was evidence that prevalence was generally higher in males compared with females and increased incrementally with greater BMI. There was evidence for differences between regions in clinical population studies, with estimated prevalence being highest in Asia. There was no evidence that prevalence changed over time. Prevalence estimates in studies of children/adolescents attending obesity clinics and in obese children/adolescents from the general population were substantially lower when elevated alanine aminotransferase (ALT was used to assess NAFLD compared with biopsies, ultrasound scan (USS or magnetic resonance imaging (MRI.Our review suggests the prevalence of NAFLD in young people is high, particularly in those who are obese and in males.

Full Text Available The age-specific prevalence of antibodies to hepatitis A virus (anti-HAV was determined in two different population groups with low socio-economic status from Rio de Janeiro city, Brazil, whose serum samples were collected 17 years apart (Population 1, 1978; Population 2, 1995. In Population 2, analysis of the anti-HAV prevalence was also carried out with respect to environmental factors. Population 1 was composed of 520 stored sera collected from the umbilical cord of term neonates and children aged 1 month to 6 years. In population 2, 720 serum samples were collected from children and adolescents with ages ranging from 1 to 23 years. The overall prevalence rate of anti-HAV in Population 1 and Population 2 was 65.6% and 32.1%, respectively. In Population 1, the anti-HAV prevalence reached 88% at the age of 3, while in Population 2, it increased from 4.5% in children under the age of 3 to 66% in the group of adolescents over the age of 14. The low exposure to HAV infection in younger children from Population 2 could be a result of improved environmental hygiene and sanitation, as demonstrated by the presence of piped water, waste and sewage disposal systems in most houses from this population group. These findings indicate a possible change in the prevalence of hepatitis A in Rio de Janeiro

Full Text Available Background and Objective: Childhood obesity is an important risk factor for the development of metabolic syndrome (MS in children and adolescent. Because of high prevalence of insulin resistance and MS in Indian adult population, studies are needed to identify the prevalence of these metabolic abnormalities in the adolescent population. The objective of this study was to estimate the prevalence of MS using pediatric International Diabetic Federation (IDF definition and compare it with estimates of Adult Treatment Panel III (ATP III definition among adolescents in Northern India. Materials and Methods: At a total of 899 adolescents attending school (aged 10-18 years participated in this population-based prospective study. All the clinical and biochemical assessment were done after proper consent. The MS was determined by the National Cholesterol Education Program ATP III definition modified for age and pediatric IDF definition. Results: The prevalence of MS was 3.5% according to ATP III criteria and 1.5% based on IDF criteria. No significant gender difference was observed in the distribution of MS. Hypertriglyceridemia was the most common and abdominal obesity the least common constituent of MS. Conclusion: This study provides the first estimates of MS using pediatric IDF definition in the adolescent population from Northern India.

Increasing adolescent HIV prevalence in Eastern Zimbabwe--evidence of long-term survivors of mother-to-child transmission?

Directory of Open Access Journals (Sweden)

Jeffrey W Eaton

Full Text Available Recent data from the Manicaland HIV/STD Prevention Project, a general-population open HIV cohort study, suggested that between 2004 and 2007 HIV prevalence amongst males aged 15-17 years in eastern Zimbabwe increased from 1.20% to 2.23%, and in females remained unchanged at 2.23% to 2.39%, while prevalence continued to decline in the rest of the adult population. We assess whether the more likely source of the increase in adolescent HIV prevalence is recent sexual HIV acquisition, or the aging of long-term survivors of perinatal HIV acquisition that occurred during the early growth of the epidemic. Using data collected between August 2006 and November 2008, we investigated associations between adolescent HIV and (1 maternal orphanhood and maternal HIV status, (2 reported sexual behaviour, and (3 reporting recurring sickness or chronic illness, suggesting infected adolescents might be in a late stage of HIV infection. HIV-infected adolescent males were more likely to be maternal orphans (RR = 2.97, p<0.001 and both HIV-infected adolescent males and females were more likely to be maternal orphans or have an HIV-infected mother (male RR = 1.83, p<0.001; female RR = 16.6, p<0.001. None of 22 HIV-infected adolescent males and only three of 23 HIV-infected females reported ever having had sex. HIV-infected adolescents were 60% more likely to report illness than HIV-infected young adults. Taken together, all three hypotheses suggest that recent increases in adolescent HIV prevalence in eastern Zimbabwe are more likely attributable to long-term survival of mother-to-child transmission rather than increases in risky sexual behaviour. HIV prevalence in adolescents and young adults cannot be used as a surrogate for recent HIV incidence, and health systems should prepare for increasing numbers of long-term infected adolescents.

Although there have been numerous studies examining the prevalence of overweight and obesity among children and adolescents with intellectual disabilities, they have not yet been integrated and synthesized through a systematic quantitative review process. The purpose of this systematic review and meta-analysis was to determine: (i) the prevalence of overweight/obesity among children and adolescents with intellectual disabilities; (ii) the sources of heterogeneity in studies reporting the prevalence of overweight/obesity in this population; and (iii) the risk of overweight/obesity in this population compared with their typically developing peers. A systematic literature search was performed and 16 studies, published between 1985 and 2015, met the inclusion criteria. The resulting pooled prevalence estimates for overweight, overweight-obesity and obesity were respectively: (i) 15%, 30%, and 13%, in children; and (ii) 18%, 33%, and 15% in adolescents. Subgroup analyses showed significant variations in the pooled prevalence estimates as a function of geographical region, recruitment setting, additional diagnoses, and norms used to define overweight or obesity. The findings also showed adolescents with intellectual disabilities to be respectively 1.54 and 1.80 times more at risk of overweight-obesity and obesity than typically developing adolescents. Unfortunately, no such comparison is available for children. © 2016 World Obesity. © 2016 World Obesity.

The aim of the current study was to examine sleep patterns and rates of insomnia in a population-based study of adolescents aged 16-19 years. Gender differences in sleep patterns and insomnia, as well as a comparison of insomnia rates according to DSM-IV, DSM-V and quantitative criteria for insomnia (Behav. Res. Ther., 41, 2003, 427), were explored. We used a large population-based study in Hordaland county in Norway, conducted in 2012. The sample included 10,220 adolescents aged 16-18 years (54% girls). Self-reported sleep measurements included bedtime, rise time, time in bed, sleep duration, sleep efficiency, sleep onset latency, wake after sleep onset, rate and frequency and duration of difficulties initiating and maintaining sleep and rate and frequency of tiredness and sleepiness. The adolescents reported short sleep duration on weekdays (mean 6:25 hours), resulting in a sleep deficiency of about 2 h. A majority of the adolescents (65%) reported sleep onset latency exceeding 30 min. Girls reported longer sleep onset latency and a higher rate of insomnia than boys, while boys reported later bedtimes and a larger weekday-weekend discrepancy on several sleep parameters. Insomnia prevalence rates ranged from a total prevalence of 23.8 (DSM-IV criteria), 18.5 (DSM-V criteria) and 13.6% (quantitative criteria for insomnia). We conclude that short sleep duration, long sleep onset latency and insomnia were prevalent in adolescents. This warrants attention as a public health concern in this age group. © 2013 European Sleep Research Society.

Congenital heart defects (CHDs) are the most common birth defects in the United States, and the population of individuals living with CHDs is growing. Though CHD prevalence in infancy has been well characterized, better prevalence estimates among children and adolescents in the United States are still needed. We used capture-recapture methods to estimate CHD prevalence among adolescents residing in 11 New York counties. The three data sources used for analysis included Statewide Planning and Research Cooperative System (SPARCS) hospital inpatient records, SPARCS outpatient records, and medical records provided by seven pediatric congenital cardiac clinics from 2008 to 2010. Bayesian log-linear models were fit using the R package Conting to account for dataset dependencies and heterogeneous catchability. A total of 2537 adolescent CHD cases were captured in our three data sources. Forty-four cases were identified in all data sources, 283 cases were identified in two of three data sources, and 2210 cases were identified in a single data source. The final model yielded an estimated total adolescent CHD population of 3845, indicating that 66% of the cases in the catchment area were identified in the case-identifying data sources. Based on 2010 Census estimates, we estimated adolescent CHD prevalence as 6.4 CHD cases per 1000 adolescents (95% confidence interval: 6.2-6.6). We used capture-recapture methodology with a population-based surveillance system in New York to estimate CHD prevalence among adolescents. Future research incorporating additional data sources may improve prevalence estimates in this population.

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.

This study examined national trends in 12-month prevalence of major depressive episodes (MDEs) in adolescents and young adults overall and in different sociodemographic groups, as well as trends in depression treatment between 2005 and 2014. Data were drawn from the National Surveys on Drug Use and Health for 2005 to 2014, which are annual cross-sectional surveys of the US general population. Participants included 172 495 adolescents aged 12 to 17 and 178 755 adults aged 18 to 25. Time trends in 12-month prevalence of MDEs were examined overall and in different subgroups, as were time trends in the use of treatment services. The 12-month prevalence of MDEs increased from 8.7% in 2005 to 11.3% in 2014 in adolescents and from 8.8% to 9.6% in young adults (both P age range of 12 to 20 years. The trends remained significant after adjustment for substance use disorders and sociodemographic factors. Mental health care contacts overall did not change over time; however, the use of specialty mental health providers increased in adolescents and young adults, and the use of prescription medications and inpatient hospitalizations increased in adolescents. The prevalence of depression in adolescents and young adults has increased in recent years. In the context of little change in mental health treatments, trends in prevalence translate into a growing number of young people with untreated depression. The findings call for renewed efforts to expand service capacity to best meet the mental health care needs of this age group. Copyright © 2016 by the American Academy of Pediatrics.

The ever increasing epidemics of overweight and obesity in school children may be one of the reasons of the growing numbers of children with incorrect body posture. The purpose of the study was the assessment of the prevalence of incorrect body posture in children and adolescents with overweight and obesity in Poznań, Poland. The population subject to study consisted of 2732 boys and girls aged 3-18 with obesity, overweight, and standard body mass. The assessment of body mass was performed based on BMI, adopting Cole's cutoff values. The evaluation of body posture was performed according to the postural error chart based on criteria complied by professor Dega. The prevalence rates of postural errors were significantly higher among children and adolescents with overweight and obesity than among the group with standard body mass. In the overweight group, it amounted to 69.2% and in the obese group to 78.6%.  The most common postural deviations in obese children and adolescents were valgus knees and flat feet. Overweight and obesity in children and adolescents, predisposing to higher incidence of some types of postural errors, call for prevention programs addressing both health problems. What is Known: • The increase in the prevalence of overweight and obesity among children and adolescents has drawn attention to additional health complications which may occur in this population such as occurrence of incorrect body posture. What is New: • The modified chart of postural errors proved to be an effective tool in the assessment of incorrect body posture. • This chart may be used in the assessment of posture during screening tests and prevention actions at school.

We estimated the prevalence of obesity, overweight, and underweight among US adolescents with and without autism and other learning and behavioral developmental disabilities (DDs) and assessed the health consequences of obesity among adolescents with DDs. From the 2008 to 2010 National Health Interview Survey, we selected 9,619 adolescents ages 12–17 years. Parent respondents reported weight, height, presence of DDs and health conditions. We calculated body mass index (BMI) and defined obesity, overweight, and underweight as ≥95th, ≥85th to learning disorder/other developmental delay. We compared BMI outcomes among adolescents in each DD group versus adolescents without DDs using multivariable logistic regression. Socio-demographic factors and birthweight were included as confounders. Estimates were weighted to reflect the US population. Both obesity and underweight prevalences were higher among adolescents with than without DDs [adjusted prevalence ratios (aPR) 1.5 (1.25–1.75) and 1.5 (1.01–2.20), respectively]. Obesity was elevated among adolescents with all DD types, and was highest among the autism subgroup [aPR 2.1 (1.44–3.16)]. Adolescents with either a DD or obesity had higher prevalences of common respiratory, gastrointestinal, dermatological and neurological conditions/symptoms than nonobese adolescents without DDs. Adolescents with both DDs and obesity had the highest estimates for most conditions. Obesity is high among adolescents with autism and other DDs and poses added chronic health risks. Obesity prevention and management approaches for this vulnerable population subgroup need further consideration. PMID:24553796

The aim of the study was to evaluate the prevalence and severity of dental caries among 18-year-old Lithuanian adolescents and to disclose possible differences in the prevalence and severity of dental caries related to gender, urbanization, and different county. A total of 1063 18-year-old adolescents attending school, 427 boys and 636 girls from 10 Lithuanian counties including urban and rural areas, were included in the cross-sectional study on dental caries. The method of multistage cluster sampling was used. The dental examination was performed according to the methodology of oral status evaluation recommendations by the World Health Organization (WHO). The prevalence of dental caries, DMFT score, Significant Caries Index, and dental care index were determined. The overall prevalence of dental caries among 18-year-old Lithuanian adolescents was 78.3%. The study population had a mean DMFT score of 2.93 [SD, 2.81]. Considering the gender, a higher DMFT score was observed among girls than boys (3.03 [SD, 2.88] versus 2.73 [SD, 2.71]) and in rural than urban areas (3.02 [SD, 2.98] versus 2.89 [SD, 2.73]). The Significant Caries Index and the dental care index among 18-year-old adolescents were 6.14 and 62.3%, respectively. This study showed a relatively high prevalence of dental caries. The existing differences of caries experience between the urban and the rural areas as well as between the counties could be influenced by the socioeconomic differences in the country.

To evaluate the prevalence of elevated glycated haemoglobin (HbA1c) levels in a population of adolescents participating in the Study of Cardiovascular Risk in Adolescents. This is a school-based cross-sectional study based on a complex sample of adolescents 12-17years old representative at the national and macro-regional levels and for each Brazilian state capital. Blood was collected in schools and then evaluated in a single laboratory. HbA1c levels were considered elevated if ⩾5.7% (39mmol/mol) and were analyzed according to sex, age, macro-region, type of school, skin color, and nutritional status. Data from 37,804 adolescents were analyzed. The mean level of HbA1c was 5.4% (95%CI 5.4-5.4) (36mmol/mol [95%CI 36-36]), and 20.5% (95%CI 19.1-22.0) of adolescents presented values ⩾5.7% (⩾39mmol/mol). Among males, 23.6% (95%CI 21.8-25.6) showed elevated HbA1c levels compared to 17.5% (95%CI 15.9-19.2) observed in females. The prevalence of elevated levels of HbA1c was higher in adolescents with black skin color (27.6%; 95%CI 23.2-32.4) vs. white skin color (16.9%; 95%CI 15.4-18.5), and higher in those who studied in public schools (21.6%; 95%CI 20.0-23.4) vs. private schools (16.7%; 95%CI 14.7-19.0). Among obese adolescents, 29.7% (95%CI 25.4-34.3) had elevated levels of HbA1c, compared to 19.3% (95%CI 18.0-20.7) in normal weight students and 19.7% (95%CI 17.1-22.6) in overweight adolescents. Obese male adolescents of lower socioeconomic status had a higher prevalence of elevated HbA1c levels. Our findings highlight the importance of focusing on this high risk group for interventions to prevent diabetes. Copyright © 2017 Elsevier B.V. All rights reserved.

Arterial hypertension is a major public health problem and has increased considerably in young individuals in past years. Thus, identifying factors associated with this condition is important to guide intervention strategies in this population. To determine high blood pressure prevalence and its associated factors in adolescents. A random sample of 1,242 students enrolled in public schools of the city of Curitiba (PR) was selected. Self-administered questionnaires provided family history of hypertension, daily energy expenditure, smoking habit, daily fat intake, and socioeconomic status. Waist circumference was measured following standardized procedures, and blood pressure was measured with appropriate cuffs in 2 consecutive days to confirm high blood pressure. Relative frequency and confidence interval (95%CI) indicated high blood pressure prevalence. Bivariate and multivariate analyses assessed the association of risk factors with high blood pressure. The high blood pressure prevalence was 18.2% (95%CI 15.2-21.6). Individuals whose both parents had hypertension [odds ratio (OR), 2.22; 95%CI 1.28-3.85] and those with high waist circumference (OR, 2.1; 95%CI 1.34-3.28) had higher chances to develop high blood pressure. Positive family history of hypertension and high waist circumference were associated with high blood pressure in adolescents. These factors are important to guide future interventions in this population.

Voluntarily sending sexual content (e.g., photos, videos) among adolescents via the Internet and mobile phones, a phenomenon called sexting , is receiving increasing social and research attention. The aims of this study were: 1) to analyze the prevalence and trends of sexting among adolescents by gender and age and 2) to examine the personality profile of adolescents that participated in sexting. The sample consisted of 3,223 Spanish adolescents from 12 to 17 years of age (49.9% female; mean age = 14.06, SD = 1.37) who anonymously and voluntarily completed self-report questionnaires on sexting and the big five personality factors. The overall prevalence of sexting was 13.5%. The prevalence was 3.4% at 12 years old and increased to 36.1% at 17 years of age, showing a growing and significant linear trend. Overall, no differences were found between males and females. The personality profile of those involved in sexting was characterized by higher Extraversion and Neuroticism and by lower scores in Conscientiousness and Agreeableness. Given its high prevalence, beyond adopting a perspective based on the dangers of sexting, an educational approach that emphasizes responsible and informed use of information and communication technologies is necessary.

To analyze the prevalence of asthma and asthma symptoms in students of two distinct age brackets residing in the city of Tangará da Serra, Brazil. Cross-sectional, population-based study of the prevalence of asthma in children from 6 to 7 years of age and adolescents from 13 to 14, using the standardized International Study of Asthma and Allergies in Childhood, phase 1 questionnaire, validated for use in Brazil. Students who responded affirmatively to question 2 (presence of wheezing in the preceding 12 months) were classified as suffering from asthma. The study comprised 3,362 students, of whom 1,634 (48.6%) were children and 1,728 (51.4%) were adolescents. Of the 1,634 children, 816 (49.9%) were male, and 818 (50.1%) were female. Of the 1,728 adolescents, 773 (45.0%) were male, and 955 (55.0%) were female. The prevalence of asthma among the children was 25.2%, whereas that among the adolescents was 15.9% (chi2 = 8.34; p = 0.00). The children presented higher prevalences of the following symptoms of asthma than did the adolescents: wheezing ever (54.3%), nocturnal dry cough (43.9%), wheezing in the preceding 12 months (25.2%), and from 1 to 3 attacks of wheezing in the preceding 12 months (19.1%). There were no differences between the two groups regarding physician-diagnosed asthma (approximately 4.5%). There were no statistical differences regarding the prevalence of asthma by gender in the two groups. Tangará da Serra has a high prevalence of asthma in children and adolescents, and this result is compatible with other studies carried out in Brazil and Latin America using the same methodology.

To analyse the prevalence of hypovitaminosisD and associated factors in school children and adolescents living in a region of northern Spain. Cross-sectional study (convenience sampling). Primary Health Care. A total of 602 Caucasian individuals (aged 3.1 to 15.4years) were included in the study. Prevalence of hypovitaminosisD were calculated (dependent variable). HypovitaminosisD is defined according to the US Endocrine Society criteria: deficiency (calcidiol <20ng/mL), insufficiency (calcidiol: 20-29ng/mL), and sufficiency (calcidiol ≥30ng/mL). Gender, age, body mass index, residence, and season of the year were recorded (independent variables), and their association with hypovitaminosisD was analysed by multiple regression. The prevalence of hypovitaminosisD was 60.4% (insufficiency: 44.6%; deficiency: 15.8%). Multivariate analysis showed that factors associated to hypovitaminosisD were being female (OR: 1.6; 95%CI: 1.1-2.3), pubertal age (OR: 1.8; 95%CI: 1.2-2.6), autumn (OR: 9.5; 95%CI: 4.8-18.7), winter (OR: 8.8; 95%CI: 4.5-17.5) and spring time (OR: 13.2; 95%CI: 6.4-27.5), living in urban areas (OR:1.6; CI95%: 1.1-2.2), and severe obesity (OR: 4.4; 95%CI: 1.9-10.3). There is a high prevalence of hypovitaminosisD in juvenile populations. being female, pubertal age, autumn, winter and spring seasons, severe obesity, and living in urban areas are factors associated to hypovitaminosisD. Consideration should be given to the administration of vitamin supplements and/or the increase in the ingestion of natural vitaminD dietary sources. Copyright © 2017 Elsevier España, S.L.U.

Njim, Tsi; Agbor, Valirie Ndip

2017-06-26

Adolescent pregnancies are high risk due to the increased probability of adverse outcomes; as adolescents are usually considered to be ill-equipped to deal with the burden of pregnancy. We sought to determine the prevalence of adolescent deliveries in a secondary-level care hospital in semi-urban Cameroon-Bamenda, the adverse neonatal outcomes and to assess if previous obstetric history could preclude adolescents from having adverse outcomes in their present pregnancy. The prevalence of adolescent deliveries was 8.7% (95% CI 7.01-10.73%). The neonates of adolescent mothers were more likely to have severe asphyxia (OR 4.0; 95% CI 1.2-12.9; p = 0.03) and low birth weight (OR 2.4; 95% CI 1.3-4.4; p adolescents were just as likely to have complications as multipara adolescents. The prevalence of adolescent deliveries (8.7%) in the Regional Hospital Bamenda is high. Their babies are at a high risk of adverse neonatal outcomes irrespective of their previous obstetric history (previous delivery) emphasising that adolescents are generally ill-prepared to deal with pregnancy. Strategies to reduce the prevalence of adolescent deliveries should be investigated and implemented in view of attaining the sustainable development goals.

To determine the characteristics and prevalence of previous child sexual abuse among a group of Mexican junior high school students. A total of 1067 adolescents of both genders were selected to fill out a survey about child sexual abuse. The prevalence of child sexual abuse was 18.7% (n = 200). It was more frequent in girls (58%) than in boys (42%). Sexual abuse involved physical contact in 75% of those cases reporting abuse. The aggressors were neighbours (50.3%), relatives (36.8%) and strangers (13.9%). Abuse was committed through deception in 90% of the cases and involved physical mistreatment in 10% of the cases. Of the victims, 14.4% had spoken about the problem and 3.7% had taken legal action. And 9.6% of those surveyed stated that they required psychological counselling. In the population studied, the prevalency of child sexual abuse was greater than that reported in Mexico City (4.3-8.4%), although it was similar to that found in the Spanish child population (15-23%). The risk of sexual abuse is greater for girls and the principal aggressors are male neighbours, family friends and relatives; the abuse is committed in the home of the aggressor or the victim and very few cases are reported to the authorities.

The problematic use of mobile phones among adolescents has not been widely studied. There are very few instruments for assessing potential technological addiction to mobile phones, or for categorizing different types of users or uses. The most widely used scale is the Mobile Phone Problem Use Scale (MPPUS), which is used to study adult populations, and has been applied in various forms in international contexts. The aims of this study were to adapt the Spanish version of this scale (MPPUSA) to British adolescents, and then to estimate the prevalence of possible problematic users. A questionnaire was administered to a sample of 1,529 secondary school pupils aged between 11 and 18 years, with 1,026 completed questionnaires being collected. The analysis showed that the factor and construct validity and reliability were comparable to those obtained in previous studies. The prevalence of problematic users among the students was 10%, and the typical problematic user tended to be an adolescent between 11 and 14 years old, studying in a public school, who considered themselves to be an expert user of this technology, who made extensive use of his/her mobile phone, and who attributed the same problem of use among their peers. These users presented notable scores in all the symptoms covered by the scale used to assess problematic use. In conclusion, the adaptation of the MPPUSA as a screening scale for British adolescents presents good sensitivity and specificity for detecting the main addictive symptoms proposed in this validated version.

Prevalence and correlates of contraceptive use among female adolescents in Ghana.

2015-08-19

Adolescence is a critical stage in the life course and evidence suggests that even though contraceptive use has been steadily increasing among women in Ghana over the past years, contraceptive prevalence and determinants among female adolescents is quite lacking. This paper examines the prevalence and correlates of contraceptive use among female adolescents in Ghana. The paper used data from the 2008 Ghana Demographic and Health survey. Bivariate analysis was carried out to determine the contraceptive prevalence among female adolescents while logistic regression analysis was applied to examine the correlates of female adolescent contraceptive use. The study founded that female adolescent contraceptive use was significantly determined by age of adolescent, education, work status, knowledge of ovulatory cycle, visit of health facility and marital status. This has implications for adolescent sexual and reproductive health programmes in Ghana. It is therefore essential to intensify girl child education and strengthen the provision of family planning information and services for female adolescents in the country.

Mørtz, Charlotte G; Andersen, Klaus Ejner; Bindslev-Jensen, Carsten

2005-01-01

In the last decade an increased occurrence of peanut hypersensitivity and severe anaphylactic reactions to peanut have been reported. However, few prevalence studies have been performed in unselected populations. This study evaluated the point prevalence of peanut hypersensitivity in Danish...... adolescents. The point prevalence of peanut allergy confirmed by oral challenge was estimated to 0.5%. The number of adolescents sensitized to peanut by specific immunoglobulin E (IgE) (CAP FEIA) and skin prick test (SPT) were higher (5.8% resp. 3.4%). In adolescents without clinically relevant peanut...... sensitization most cases were sensitized to grass pollen and the IgE class for grass was higher than for peanut. A correlation between peanut and pollen (grass) sensitization is therefore plausible. Before a positive SPT or specific IgE measurement to peanut is considered clinically relevant in a patient...

Scarcity of reliable data on food allergy prevalence exists in Turkey. We aimed to assess reported and confirmed IgE-mediated food allergy prevalence, and define the spectrum of allergenic food. We prospectively evaluated the ISAAC Phase II study population for food allergy. Participants that reported experiencing food allergy symptom in the last year and/or were skin prick test positive for a predefined list of food allergens, were interviewed via telephone, and those considered as having food allergy were invited to undergo clinical investigation, including challenge tests. A total of 6963 questionnaires were available. Parental reported food allergy prevalence and skin prick sensitisation rate were 20.2 ± 0.9% and 5.9 ± 0.6%. According to the above-defined criteria, 1162 children (symptom positive n=909, skin prick test positive n=301, both positive n=48) were selected and 813 (70.0%) were interviewed via telephone. Out of 152 adolescents reporting a current complaint, 87 accepted clinical investigation. There were 12 food allergies diagnosed in nine adolescents, with food allergy prevalence of 0.16 ± 0.11%. The most common foods involved in allergic reactions were walnut (n=3) and beef meat (n=2), followed by hen's egg (n=1), peanut (n=1), spinach (n=1), kiwi (n=1), cheese (n=1), hazelnut (n=1) and peach (n=1). While parental reported food allergy prevalence was within the range reported previously, confirmed IgE-mediated food allergy prevalence among adolescents was at least 0.16%, and the spectrum of foods involved in allergy differed from Western countries, implying environmental factors may play a role.

We estimated the prevalence of obesity, overweight, and underweight among US adolescents with and without autism and other learning and behavioral developmental disabilities (DDs) and assessed the health consequences of obesity among adolescents with DDs. From the 2008 to 2010 National Health Interview Survey, we selected 9,619 adolescents ages 12-17 years. Parent respondents reported weight, height, presence of DDs and health conditions. We calculated body mass index (BMI) and defined obesity, overweight, and underweight as ≥95th, ≥85th to obesity and underweight prevalences were higher among adolescents with than without DDs [adjusted prevalence ratios (aPR) 1.5 (1.25-1.75) and 1.5 (1.01-2.20), respectively]. Obesity was elevated among adolescents with all DD types, and was highest among the autism subgroup [aPR 2.1 (1.44-3.16)]. Adolescents with either a DD or obesity had higher prevalences of common respiratory, gastrointestinal, dermatological and neurological conditions/symptoms than nonobese adolescents without DDs. Adolescents with both DDs and obesity had the highest estimates for most conditions. Obesity is high among adolescents with autism and other DDs and poses added chronic health risks. Obesity prevention and management approaches for this vulnerable population subgroup need further consideration.

Although the prevalence of adolescents' cigarette smoking has increased in recent decades, little is known regarding its epidemiology in certain Saudi regions, including the Madinah region. The aim of this study was to determine the prevalence and predictors of adolescent cigarette smoking in Madinah, Saudi Arabia. A school-based cross-sectional study was carried out in the Madinah region during 2013. A multistage stratified cluster sample was taken and included 3400 students (11-19 years) from 34 intermediate and secondary schools. Data concerning sociodemographic and smoking-related factors were collected using a valid and reliable self-administered questionnaire. The prevalence of smoking was estimated, and appropriate statistical analyses were performed, including univariate, predictive and multivariate regression analyses. The overall response rate was 97.7%. The prevalence of cigarette smoking in the respondents' 3322 adolescents was 15.17% (95% CI = 13.95-16.39) with significant differences in sociodemographic factors. The most important predictors were most or all friends smoking (OR = 12.5; 95% CI = 9.40-16.8). Other significant less important factors were parental smoking, belief in the harmful effects of smoking, cigarette advertisement in mass media, and pocket money. Cigarette smoking prevalence is a relatively low among adolescents in Madinah region. However, friends and parents smoking play an important role in the increased risk of smoking in the studied adolescents. These predictors must be included in any antismoking education programs targeting to this sector of population in the region.

[Spanish adaptation of the "Mobile Phone Problem Use Scale" for adolescent population].

López-Fernández, Olatz; Honrubia-Serrano, Ma Luisa; Freixa-Blanxart, Montserrat

2012-01-01

Problematic use of the mobile telephone is an emerging phenomenon in our society, and one which particularly affects the teenage population. Knowledge from research on the problematic use of this technology is necessary, since such use can give rise to a behavioural pattern with addictive characteristics. There are hardly any scales for measuring possible problematic use of mobile phones, and none at all adapted exclusively for the Spanish adolescent population. The scale most widely used internationally is the Mobile Phone Problem Use Scale (MPPUS). The aim of the present study is to adapt the MPPUS for use with Spanish adolescents. The Spanish version of the questionnaire was administered to a sample of 1132 adolescents aged 12 to 18. Reliability and factorial validity were comparable to those obtained in adult population, so that the measure of problematic mobile phone use in Spanish teenagers is one-dimensional. A prevalence of 14.8% of problematic users was detected.

Full Text Available Abstract Background The aim of this work is to estimate the French frequencies of dispensed psychotropic prescriptions in children and adolescents. Prevalence estimations of dispensed prescriptions are compared to the frequencies of use of psychotropic reported by 17 year-old adolescents. Methods Prescription data is derived from national health insurance databases. Frequencies of dispensed prescriptions are extrapolated to estimate a range for the 2004 national rates. Self-report data is derived from the 2003 and 2005 ESCAPAD study, an epidemiological study based on a questionnaire focused on health and drug consumption. Results The prevalence estimation shows that the prevalence of prescription of a psychotropic medication to young persons between 3 and 18 years is about 2.2%. In 2005, the self-report study (ESCAPAD shows that 14.9% of 17 year-old adolescents took medication for "nerves" or "to sleep" during the previous 12 months. The same study in 2003 also shows that 62.3% of adolescents aged 17 and 18 reporting psychotropic use, took the medication for anxiety and 56.8% to sleep. Only 49.7% of these medications are suggested by a doctor. Conclusion This study underlines a similar range of prevalence of psychotropic prescriptions in France to that observed in other European countries. Nevertheless, the proportion of antipsychotics and benzodiazepines seems to be higher, whereas the proportion of methylphenidate is lower. Secondly, a disparity between the prevalence of dispensed prescriptions and the self-report of actual use of psychotropics has been highlighted by the ESCAPAD study which shows that these treatments are widely used as "self-medication".

Full Text Available ABSTRACT OBJECTIVE To estimate the prevalence of hypertension among adolescent Brazilian students. METHODS A systematic review of school-based cross-sectional studies was conducted. The articles were searched in the databases MEDLINE, Embase, Scopus, LILACS, SciELO, Web of Science, CAPES thesis database and Trip Database. In addition, we examined the lists of references of relevant studies to identify potentially eligible articles. No restrictions regarding publication date, language, or status applied. The studies were selected by two independent evaluators, who also extracted the data and assessed the methodological quality following eight criteria related to sampling, measuring blood pressure, and presenting results. The meta-analysis was calculated using a random effects model and analyses were performed to investigate heterogeneity. RESULTS We retrieved 1,577 articles from the search and included 22 in the review. The included articles corresponded to 14,115 adolescents, 51.2% (n = 7,230 female. We observed a variety of techniques, equipment, and references used. The prevalence of hypertension was 8.0% (95%CI 5.0–11.0; I2 = 97.6%, 9.3% (95%CI 5.6–13.6; I2 = 96.4% in males and 6.5% (95%CI 4.2–9.1; I2 = 94.2% in females. The meta-regression failed to identify the causes of the heterogeneity among studies. CONCLUSIONS Despite the differences found in the methodologies of the included studies, the results of this systematic review indicate that hypertension is prevalent in the Brazilian adolescent school population. For future investigations, we suggest the standardization of techniques, equipment, and references, aiming at improving the methodological quality of the studies.

Studies investigating the prevalence of positive mental health and its correlates are still scarce compared to the studies on mental disorders, although there is growing interest of assessing positive mental health in adolescents. So far, no other study examining the prevalence and determinants of positive mental health in Chinese adolescents has been found. The purpose of this study was to assess the prevalence and correlates of positive mental health in Chinese adolescents. This cross-sectional study used a questionnaire including Mental Health Continuum-Short Form (MHC-SF) and items regarding multiple aspects of adolescent life. The sample involved a total of 5399 students from grade 8 and 10 in Weifang, China. Multivariate Logistic regression analyses were performed to evaluate the associations between potential indicators regarding socio-economic situations, life style, social support and school life and positive mental health and calculate odds ratios and 95% confidence intervals. More than half (57.4%) of the participants were diagnosed as flourishing. The correlated factors of positive mental health in regression models included gender, perceived family economy, the occurrence of sibling(s), satisfaction of self-appearance, physical activity, sleep quality, stress, social trust, desire to learn, support from teachers and parents as well as whether being bullied at school (OR ranging from 1.23 to 2.75). The Hosmer-Lemeshow p-value for the final regression model (0.45) indicated adequate model fit. This study gives the first overview on prevalence and correlates of positive mental health in Chinese adolescents. The prevalence of positive mental health in Chinese adolescents is higher than reported in most of the previous studies also using MHC-SF. Our findings suggest that adolescents with advantageous socio-economic situations, life style, social support and school life are experiencing better positive mental health than others.

Population-based studies estimating prevalence's of white-coat, masked and sustained hypertension in non-European adolescents are needed, particularly in developing countries. Aiming to determine these estimates and, additionally identify factors associated to these conditions this study was conducted. Cross-sectional study with a representative sample of secondary school students from a Brazilian state capital. Office measurements were performed with validated semi-automatic devices. Home BP (blood pressure) monitoring protocol included two day-time and two evening-time measurements over 6 days. Adolescents' were classified as: normotensives (office and home BP coat hypertensives (office BP ≥95th percentile and home BP coat, masked and sustained hypertension. In a sample of 1024 adolescents, prevalence of white-coat, masked and sustained hypertension was 7.5%, 2.2% and 1.7%, respectively. Male sex was positively associated with white-coat hypertension (OR 2.68; 95%CI 1.58-4.54; p coat (OR 1.23; 95%CI 1.16-1.30; p coat hypertension, masked and sustained hypertension in a population of non-European adolescents assessed by home BP monitoring was 7.5%, 2.2% and 1.7% respectively. Male sex was positively associated with white-coat hypertension in these adolescents while BMI was positively associated with both white-coat and sustained hypertension.

Methods: This was a cross-sectional school-based epidemiological study with 2874 high school adolescents with age 14-19 years (57.8% female from public and private schools in the city of João Pessoa, PB, Northeast Brazil. Excessive screen time was defined as watching television and playing video games or using the computer for more than 2 h/day. The associated factors analyzed were: sociodemographic (gender, age, economic class, and skin color, physical activity and nutritional status of adolescents. Results: The prevalence of excessive screen time was 79.5% (95%CI 78.1-81.1 and it was higher in males (84.3% compared to females (76.1%; p<0.001. In multivariate analysis, adolescent males, those aged 14-15 year old and the highest economic class had higher chances of exposure to excessive screen time. The level of physical activity and nutritional status of adolescents were not associated with excessive screen time. Conclusions: The prevalence of excessive screen time was high and varied according to sociodemographic characteristics of adolescents. It is necessary to develop interventions to reduce the excessive screen time among adolescents, particularly in subgroups with higher exposure.

Family violence is a social and public health issue across the world for many populations and affects many different types of people, for example, children, women, and vulnerable adults. Adolescents are one of the main victims of this important phenomenon. This article estimates the prevalence of family violence in adolescents and associated factors. The study was carried out in 2012 with a probability and representative sample of 656 adolescents aged between 11 and 17 years who were enrolled at public schools located in the extreme South of the city of São Paulo. The association was tested by the proportion test, Pearson's chi-square or Fischer's exact test, and Poisson regression adjusted by robust variance estimation, considering a level of significance of 5%. Among adolescents, 38.9% reported having been victims of family violence. Women were victimized with higher frequency (44.1%). The factors associated with prevalence of family violence were being of the female sex (prevalence ratio [PR] = 1.47; 95% confidence interval [CI] = [1.20, 1.80]) and living only with the father (PR = 1.52; 95% CI = [1.11, 2.08]). The prevalence of adolescents who were victims of family violence is high; however, special attention must be paid to women and adolescents who live only with their father-they were established, in this study, as a risk group. Epidemiological studies of this nature are important to reveal the reality of family violence and to aid the construction of intersectoral public policies to promote health, prevent violence, and foster a peaceful culture. © The Author(s) 2015.

The main purpose of this study was to examine the prevalence of symptoms of an emotional and behavioral nature, as well as prosocial type capabilities, measured using the Strengths and Difficulties Questionnaire, in non-clinical adolescents. The final sample was composed of a total of 508 students, 208 male (40.9%). The age of participants ranged from 11 to 18 years (M=13.91 years; SD=1.71). The results show that a significant number of adolescents self-reported emotional and behavioral problems. The mean scores of the Strengths and Difficulties Questionnaire subscales varied according the gender and age of the adolescents. In the present study, the prevalence of psychological difficulties among adolescents was similar to that reported in other national and international studies. In view of these results, there is a need to develop programs for the early detection of these types of problems in schools in children and adolescents ages. Copyright © 2013 SEP y SEPB.

The present study aimed to assess the adequacy of Ca intake and major food sources of Ca in Korean children and adolescents. A cross-sectional study. Data from the Korean National Health and Nutrition Examination Survey (KNHANES) 2007-2010. We analysed the daily Ca intake, major food sources of Ca and the prevalence of inadequate Ca intake in the study population. Ca intake was categorized as inadequate when the participant's daily Ca intake was less than the Estimated Average Requirement. Subject The study population consisted of 7233 children and adolescents (3973 boys, 3260 girls; aged 1-18 years). Mean Ca intake was 510·2 mg/d in boys and 431·7 mg/d in girls. Overall, 75·0 % of adolescents (boys 71·6 %, girls 79·1 %) had inadequate Ca intake. The prevalence of inadequate Ca intake increased significantly from toddlers (45-55 %) to adolescents (78-86 %) in both genders. The highest ranked food sources for Ca were dairy products (35·0 %), followed by vegetables (17·3 %), grains (11·3 %) and seafood (9·9 %). Ca intake from dairy products decreased significantly from 57 % in toddlers to 30 % in adolescents, while Ca intakes from other foods increased with age. Inadequate Ca intake is highly prevalent and increased with age in Korean children and adolescents. It should be emphasized to encourage children and adolescents to eat more Ca-rich products to meet their Ca needs.

Despite evidence that children of male war veterans with combat-related posttraumatic stress disorder (PTSD) are at particularly high risk for behavior problems, very little is currently known about suicidal behaviors in this population of youth. This study aimed to examine the prevalence and psychosocial correlates of suicide attempts among psychiatrically hospitalized adolescent offspring of Croatian male PTSD veterans. Participants were psychiatric inpatients, ages 12-18 years. Self-report questionnaires assessed demographics, suicide attempts, psychopathology, parenting style, and family functioning. The prevalence of suicide attempts was 61.5% (65.2% for girls and 58.0% for boys). Internalizing symptoms, family dysfunction, lower levels of maternal and paternal care, and paternal overcontrol were significantly associated with suicide attempts. Our findings suggest that suicide attempts are common among inpatient adolescent offspring of male PTSD veterans and that interventions targeting both adolescent psychopathology and family relationships are needed for adolescents who have attempted suicide.

Full Text Available ABSTRACT OBJECTIVE To describe the prevalence of common mental disorders in Brazilian adolescent students, according to geographical macro-regions, school type, sex, and age. METHODS We evaluated 74,589 adolescents who participated in the Cardiovascular Risk Study in Adolescents (ERICA, a cross-sectional, national, school-based study conducted in 2013-2014 in cities with more than 100,000 inhabitants. A self-administered questionnaire and an electronic data collector were employed. The presence of common mental disorders was assessed using the General Health Questionnaire (GHQ-12. We estimated prevalence and 95% confidence intervals of common mental disorders by sex, age, and school type, in Brazil and in the macro-regions, considering the sample design. RESULTS The prevalence of common mental disorders was of 30.0% (95%CI 29.2-30.8, being higher among girls (38.4%; 95%CI 37.1-39.7 when compared to boys (21.6%; 95%CI 20.5-22.8, and among adolescents who were from 15 to 17 years old (33.6%; 95%CI 32.2-35.0 compared to those aged between 12 and 14 years (26.7%; 95%CI 25.8-27.6. The prevalence of common mental disorders increased with age for both sexes, always higher in girls (ranging from 28.1% at 12 years to 44.1% at 17 years than in boys (ranging from 18.5% at 12 years to 27.7% at 17 years. We did not observe any significant difference by macro-region or school type. Stratified analyses showed higher prevalence of common mental disorders among girls aged from 15 to 17 years of private schools in the North region (53.1; 95%CI 46.8-59.4. CONCLUSIONS The high prevalence of common mental disorders among adolescents and the fact that the symptoms are often vague mean these disorders are not so easily identified by school administrators or even by health services. The results of this study can help the proposition of more specific prevention and control measures, focused on highest risk subgroups.

Full Text Available Background: Dyslipidemia is considered as an important modifiable risk factor for cardiovascular disease (CVD. The link between childhood dyslipidemia and occurrence of atherosclerosis and its sequels in adulthood are well-documented. This study aimed to systematically review the prevalence of dyslipidemia among Iranian children and adolescents. Materials and Methods: An electronic search was conducted on studies published from January 1990 to January 2014. The main international electronic data sources were PubMed and the NLM Gateway (for MEDLINE, Institute of Scientific Information (ISI, and SCOPUS. For Persian databases, we used domestic databases with systematic search capability including IranMedex, Irandoc, and Scientific Information Database (SID. We included all available population-based studies and national surveys conducted in the pediatric age group (aged <21 years. Results: In this review, 1772 articles were identified (PubMed: 1464; Scopus: 11; ISI: 58; SID: 90; IranMedex: 149; Irandoc: 57. During three refine steps and after removing of duplicates, 182 articles related to the study domain were selected. After quality assessment, 46 studies were selected for text appraisal, of which 26 qualified articles were evaluated at the final step. The prevalence range of hypercholesterolemia, hypertriglyceridemia, elevated low-density lipoprotein cholesterol, and low high-density lipoprotein cholesterol (HDL-C were 3-48%, 3-50%, 5-20% and 5-88%, respectively. Low HDL-C and hypertriglyceridemia were the most prevalent lipid disorders in this group of population. Conclusion: Dyslipidemia is a common health problem among Iranian children and adolescents. Few data were available in preschool children. This finding provides useful information for health policy makers to implement action-oriented interventions for prevention and early control of this important CVD risk factor.

Little is known about the prevalence of intimate partner violence (IPV) and its associated factors among adolescents and younger women. This study analyzed data from nine countries of the WHO Multi-country Study on Women's Health and Domestic Violence against Women, a population based survey conducted in ten countries between 2000 and 2004. The lifetime prevalence of IPV ranged from 19 to 66 percent among women aged 15 to 24, with most sites reporting prevalence above 50 percent. Factors significantly associated with IPV across most sites included witnessing violence against the mother, partner's heavy drinking and involvement in fights, women's experience of unwanted first sex, frequent quarrels and partner's controlling behavior. Adolescent and young women face a substantially higher risk of experiencing IPV than older women. Adolescence and early adulthood is an important period in laying the foundation for healthy and stable relationships, and women's health and well-being overall. Ensuring that adolescents and young women enjoy relationships free of violence is an important investment in their future.

Monitoring changes in adolescent sexual risk behaviors and sexually transmitted infections is critical for evaluating the effectiveness of human immunodeficiency virus and other prevention programs, but population-based data on adolescents in Thailand are limited. We report findings from 2 cross-sectional surveys conducted in 1999 and 2002 among 15-to 21-year-old vocational students. In 1999 and 2002, 1725 and 966 students, respectively, were interviewed using computer-assisted self-interview methods. Urine samples were collected and tested for Chlamydia trachomatis and Neisseria gonorrhoeae by polymerase chain reaction. From 1999 to 2002 C. trachomatis prevalence increased from 3.2% to 7.5% (P partners among both men (3.4-4.7, P = 0.01) and women (2.5-3.3, P partners among men (1.1-2.1, P use decreased significantly among women with casual partners (43%-19%, P = 0.03) but not among men (25%-31%, P = 0.31). Our study identified important increases in the prevalence of chlamydial infection and in sexual risk behaviors among Thai adolescents over a 3-year period. These findings are consistent with other studies suggesting profound social changes are changing norms of adolescent sexual behavior in Thailand, and highlight the need for adolescent sexual health services and prevention programming.

Objectives To systematically review studies of the epidemiology of tinnitus and hyperacusis in children and young people, in order to determine the methodological differences implicated in the variability of prevalence estimates and the influence of population characteristics on childhood tinnitus and hyperacusis. Data sources Articles were retrieved from PubMed, EMBASE and Scopus databases and from the relevant reference lists using the methods described in the study protocol, which has previously been published. Reporting Items for Systematic Review (PRISMA) guidelines were followed. Eligibility criteria Studies addressing childhood prevalence, for example, children and young people aged 5–19 years. Data selection 2 reviewers independently assessed the studies for eligibility, extracted data and assessed study consistency. Owing to the heterogeneity in the methodologies among the reported studies, only narrative synthesis of the results was carried out. Results Having identified 1032 publications, 131 articles were selected and 25 articles met the inclusion criteria and had sufficient methodological consistency to be included. Prevalence estimates of tinnitus range from 4.7% to 46% in the general paediatric population and among children with normal hearing, and from 23.5% to 62.2% of population of children with hearing loss. Reported prevalence ranged from 6% to 41.9% when children with hearing loss and normal hearing were both included. The prevalence of hyperacusis varied from 3.2% to 17.1%. Conclusions Data on prevalence vary considerably according to the study design, study population and the research question posed. The age range of children studied was varied and a marked degree of variation between definitions (tinnitus, hyperacusis) and measures (severity, perception, annoyance) was observed. The lack of consistency among studies indicates the necessity of examining the epidemiology of tinnitus and hyperacusis in children and adolescents with a set of

Background Cyberbullying has established links to physical and mental health problems including depression, suicidality, substance use, and somatic symptoms. Quality reporting of cyberbullying prevalence is essential to guide evidence-based policy and prevention priorities. The purpose of this systematic review was to investigate study quality and reported prevalence among cyberbullying research studies conducted in populations of US adolescents of middle and high school age. Methods Searches of peer-reviewed literature published through June 2015 for “cyberbullying” and related terms were conducted using PubMed, PsycINFO, CINAHL Plus, and Web of Science. Included manuscripts reported cyberbullying prevalence in general populations of U.S. adolescents between the ages of 10 and 19. Using a review tool based on the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) statement, reviewers independently scored study quality on study methods, results reporting, and reported prevalence. Results Search results yielded 1,447 manuscripts; 81 manuscripts representing 58 unique studies were identified as meeting inclusion criteria. Quality scores ranged between 12 and 37 total points out of a possible 42 points (M = 26.7, SD = 4.6). Prevalence rates of cyberbullying ranged as follows: perpetration, 1% to 41%; victimization, 3% to 72%; and overlapping perpetration and victimization, 2.3% to 16.7%. Conclusions Literature on cyberbullying in US middle and high school aged students is robust in quantity but inconsistent in quality and reported prevalence. Consistent definitions and evidence-based measurement tools are needed. PMID:26576821

Body dysmorphic disorder typically begins in adolescence, yet little is known about the prevalence and correlates of the disorder in this age group. The current study aimed to explore the presenting features of adolescents meeting probable criteria for body dysmorphic disorder in a large community sample, and compare levels of comorbid psychopathology, quality of life and mental health service use between adolescents with probable body dysmorphic disorder and those without. Questionnaires were completed at school by 3149 adolescents: 63% male, aged 12-18 years ( M = 14.58). These assessed Diagnostic and Statistical Manual of Mental Disorders (4th ed.) body dysmorphic disorder criteria, past mental health service use and symptoms of body dysmorphic disorder, anxiety, depression, obsessive-compulsive disorder and eating disorders. In male participants, additional measures assessed quality of life, muscularity concerns, emotional symptoms, peer problems, conduct problems and hyperactivity. The prevalence of probable body dysmorphic disorder was 1.7%; there was no sex difference in prevalence, but older adolescents reported higher prevalence than younger adolescents. Probable body dysmorphic disorder participants reported substantially elevated levels of psychopathology, quality of life impairment and mental health service use compared to non-body dysmorphic disorder participants. The prevalence of body dysmorphic disorder in adolescents is similar to adult samples, and probable body dysmorphic disorder is associated with comorbidity, distress and functional impairment in a community sample. Further research is required to better understand the presentation of body dysmorphic disorder in adolescents, and to improve diagnosis and treatment.

Full Text Available Despite high prevalence of human papillomavirus (HPV infection and cervical cancer in Indian women, no study has been done in tribal populations whose socio-sexual lifestyle is different. Therefore, HPV screening has been carried out in pre-adolescent, adolescent and young adult tribal girls using self-collected urine samples.20-35 ml self-collected midstream urine samples were obtained from a total of 2278 healthy tribal girls (9-25 years comprising pre-adolescent, adolescent and young adults from three Indian states: Madhya Pradesh, Jharkhand and Chhattisgarh. β-globin positive 2034 samples were employed for HPV detection and genotyping.The overall prevalence of HPV infection in tribal girls was 12.9% (262/2034. More than 65% (172/262 of them were infected with HR-HPV types of which HPV16 was the most predominant type (54%. Young adult girls aged 18-25 years showed a significantly higher prevalence of HPV infection (19.2%; OR = 3.36; 95% CI 2.97-6.34, P<0.001 as compared to that in adolescent (11.4%; OR = 1.82; 95% CI 1.20-2.76, P<0.01 or pre-adolescent girls (6.6%.This is a first study showing significantly a very high prevalence of HPV infection in adolescent and young adult tribal girls possibly due to different socio-sexual behavior, indicating a serious health concern for Indian tribal women.

Body weight is highly associated with overall health status. Being severely thin or obese may impose the risk of many health problems. Early detection of body mass index (BMI) status may help to reduce the associated comorbidities. Although many studies in the literature have investigated the BMI of school adolescents in Malaysia, the data on status of body weight among school adolescents in suburban states like Terengganu is limited. This study aimed to describe the body weight status of the whole population of school adolescents in all seven districts in Terengganu, Malaysia. Using a cross-sectional study design, body weight and height were measured, and BMI was calculated and classified using WHO BMI-for-age Z-score. Data was obtained using the National Fitness Standard (SEGAK) assessment, which was uploaded in a specific Health Monitoring System (HEMS). From a total of 62,567 school adolescents, 50.7% were boys and 49.3% were girls. Girls had significantly higher BMI than boys in age groups of 13 to 15 and 16 to 17 years old. Among boys and girls, there were significant differences in mean BMI of school adolescents between rural and urban school locations in all age groups (p < 0.001). There were also significant differences in BMI between boys and girls in all districts in Terengganu, except Kemaman and Kuala Terengganu, for all age groups (p < 0.001). Overall, the prevalence of thinness, normal, overweight and obesity were 8.4, 64.6, 15.0 and 12.0%, respectively. There were significant differences between BMI categories and genders in total participants, and within rural and urban school locations (p < 0.05). In all districts except Marang and Dungun, significant difference was also found between BMI categories and genders. The prevalence of thinness, overweight and obesity in Terengganu were substantial. In this study, BMI category was associated with gender, age, school location and district. However, the actual effects of these factors on the

Most studies comparing prevalence of periodontal disease and risk factors by using partial protocols were performed in adult populations, with several studies being conducted in clinical settings. The aim of this study is to assess the accuracy of partial protocols in estimating the prevalence of periodontal outcomes in adolescents and young adults from two population-based birth cohorts from Pelotas, Brazil, and to assess differences in the estimation and strength of the effect measures when partial protocols are adopted compared to full-mouth examination. Gingival bleeding at probing among adolescents (n = 339) and young adults (n = 720) and dental calculus and periodontal probing depth among young adults were assessed using full-mouth examinations and four partial protocols: Ramfjord teeth (RT), community periodontal index (CPI), and two random diagonal quadrants (1 and 3, 2 and 4). Socioeconomic, demographic, and periodontal health-related variables were also collected. Sensitivity, absolute and relative bias, and inflation factors were calculated. Prevalence ratio for each periodontal outcome for the risk factors was estimated. Two diagonal quadrants showed better accuracy; RT had the worst, whereas CPI presented an intermediate pattern when compared to full-mouth examination. For bleeding assessment in adolescence, RT and CPI underestimated by 18.4% and 16.2%, respectively, the true outcome prevalence, whereas among young adults, all partial protocols underestimated the prevalence. All partial protocols presented similar magnitude of association measures for all investigated periodontal potential risk factors. Two diagonal quadrants protocol may be effective in identifying the risk factors for the most relevant periodontal outcomes in adolescence and in young adulthood.

Adults of the peri-urban Peruvian shantytown of Lomas de Zapallal have a high prevalence of risk factors for developing cardiovascular disease (CVD)-likely due to behavioral choices established during childhood and adolescence. To guide the development of community-based risk reduction programs, we assessed the prevalence of risk factors for developing CVD among adolescents. We collected cross sectional data from adolescents of Peruvian peri-urban shantytown to evaluate four domains of CVD risk factors: (1) clinical (blood pressure, fasting blood glucose, and blood lipids), (2) anthropometric (height, weight, and waist circumference), (3) behavioral (physical activity, diet, and substance abuse), and (4) psychosocial (mental health and violence). We enrolled 275 adolescents (56.4% female, mean age 14 years). Prevalence of overweight or obese status was 27.8%. High blood pressure was more common in males (37.4%) than females (20.5%) (p = 0.002). Total cholesterol was elevated (>170 mg/dL) in nearly half (45.5%) of the adolescents, and 71% had impaired fasting blood glucose (>100 mg/dL). Females were less likely to exercise daily (95.4%) than males (84.2%) (p = 0.002) but reported higher rates of depression (66.4%), anhedonia (67.6%), and self-harm behavior (37.9%) (all p < 0.01). Adolescents living in the peri-urban population of Puente Piedra had high prevalence of risk factors for future development of CVD; preventative efforts focused on improving nutrition, increasing physical inactivity, and addressing mental health conditions could reduce such risk factors.

This study aimed to assess the prevalence of borderline personality symptoms in 16-18 year old adolescents. In this cross sectional - descriptive study, 422 high school students (211 boys, 211 girls) aged 16-18 were selected by cluster random sampling and simple random sampling in 2011-2012. The participants were assessed using the revised diagnostic interview for borderline questionnaire (DIB-R) and demographic questionnaire. Data were analyzed using Pearson correlation coefficient and Spearman correlation coefficient. Of the participants, 0/9% (0/22 % of the 16 year olds, 0.45 % of the 17 year olds and 0/22% of the 18 year olds) were diagnosed with borderline personality symptoms. Also, the prevalence of borderline personality symptoms in boys was 0/45 % of the total sample and it was 0/45 % of the total sample in girls. With respect to the relationship between demographic variables (age, sex, location, parents' occupation, parents' kinship, parents' education and birth order) and borderline personality symptoms, only parents' kinship showed a weak correlation with borderline personality symptoms. In the view of the prevalence of 0.9% of the borderline personality symptoms in adolescents, attention should be paid to the diagnosis and treatment of this disorder. Furthermore, works need to be done to improve the mental health and quality of life of adolescents.

High blood pressure (HBP) and obesity is a well-established major risk factor for stroke and coronary heart disease. However, the literatures are scarce about these informations in adolescents from low-and-middle income countries. This school-based survey was carried out among students from Maringá (Brazil) and Buenos Aires (Argentina) selected random sampling. We studied 991 Brazilian adolescents (54.5% girls) in the age range of 14-18 years. In Argentina, we studied 933 adolescents (45.9% female) in the age range of 11-17 years. The outcomes of this study are general obesity, abdominal obesity and HBP. The associated factors analysed were gender, age and health behaviours. The prevalence of obesity was 5.8% in Brazil and 2.8% in Argentina, the prevalence of abdominal obesity was 32.7% in Brazil and 11.1% in Argentina, the prevalence of HBP was 14.9% in Brazil and 13.5% in Argentina. The multilevel analysis showed that older adolescents (>14 years old) have a little likelihood of being overweight, whereas male adolescents are more likely to be obese and have HBP. The abdominal obesity in both indicators were not associated with the independent variables. The prevalence of cardiovascular risk factors is high in Latin American adolescents independent of each country, and was associated with male gender.

Full Text Available Iron deficiency anemia is the world most prevalent nutritional problem. To investigate anemia prevalence and its relation to nutritional status, 526 children and adolescents, 284 males and 242 females, aged 7 to 14 years old, were evaluated. The studied subjects take part in a program of the Social Action Department of the city of Londrina, state of Paraná, and attend Public Educational Centers which provides them three daily meals and pedagogic assistance. These individuals belong to deprived areas in the city outskirts, where the per capita income is lower than US$500 a year. The hemoglobin dosage was determined by digital puncture and read by Hemocue portable photometer. Anemia prevalence was verified in 41.3% of the assessed population, with no significant statistical differences between males and females (p=0.412. No association between anemia and malnutrition was found. In conclusion, high prevalence of anemia was observed in this population.

Full Text Available Abstract Background Anxious parents have many concerns about the future health of their atopic infants. Paediatricians and primary care practitioners need to seek knowledge on long-term outcomes in order to cope with the increasing caseload of suspected allergy and the concerns of parents. The aim of the study was to assess suspected and diagnosed allergy in infancy as predictors of allergy and asthma in adolescence. Methods Families expecting their first baby and making their first visit to a maternity health care clinic in 1986 were selected as the study population in a random sample. There were 1278 eligible study families. The data were provided of the children at the ages of 9 and 18 months and 3, 5, 12, 15 and 18 years by health care professionals, parents, and adolescents (themselves. Results At the age of 9 months, the prevalence of allergy suspicions was distinctly higher than that of allergy diagnoses. At the age of five years suspected allergy approaches were nil, and the prevalence of diagnosed allergy was about 9%. During the adolescence, the prevalence of self-reported allergy increases steadily up to the age of 18 years, and that of asthma remains at approximately 5%. Suspected allergy at the age of 9 or 18 months and at the 5 years of age does not predict allergy at adolescence. Compared with non-allergic children, children with definite allergy at the age of 5 were over 8 times more likely to have allergy and nearly 7 times more likely to have asthma in adolescence. Conclusion An early ascertained diagnosis of allergy, but not suspicions of allergy, predicts prevailing allergy in adolescence. Efforts need to be focused on accurate diagnosis of early childhood allergies.

OBJECTIVE To describe the prevalence of eating habits considered healthy in adolescents according to sex, age, education level of the mother, school type, session of study, and geographic region. METHODS The assessed data come from the Study of Cardiovascular Risks in Adolescents (ERICA), a cross-sectional, national and school-based study. Adolescents of 1,247 schools of 124 Brazilian municipalities were evaluated using a self-administered questionnaire with a section on aspects related to eating behaviors. The following eating behaviors were considered healthy: consuming breakfast, drinking water, and having meals accompanied by parents or legal guardians. All prevalence estimates were presented proportionally, with their respective 95% confidence intervals. The Chi-square test was used to evaluate the differences in healthy eating habits prevalences according to other variables. The module survey of the Stata program version 13.0 was used to analyze complex data. RESULTS We evaluated 74,589 adolescents (72.9% of the eligible students). Of these, 55.2% were female, average age being 14.6 years (SD = 1.6). Among Brazilian adolescents, approximately half of them showed healthy eating habits when consuming breakfast, drinking five or more glasses of water a day, and having meals with parents or legal guardians. All analyzed healthy eating habits showed statistically significant differences by sex, age, type of school, session of study, or geographic region . CONCLUSIONS We suggest that specific actions of intersectoral approach are implemented for the dissemination of the benefits of healthy eating habits. Older female adolescents (15 to 17 years old) who studied in public schools, resided in the Southeast region, and whose mothers had lower education levels, should be the focus of these actions since they present lower frequencies concerning the evaluated healthy habits.

Background Despite high prevalence of human papillomavirus (HPV) infection and cervical cancer in Indian women, no study has been done in tribal populations whose socio-sexual lifestyle is different. Therefore, HPV screening has been carried out in pre-adolescent, adolescent and young adult tribal girls using self-collected urine samples. Methods 20–35 ml self-collected midstream urine samples were obtained from a total of 2278 healthy tribal girls (9–25 years) comprising pre-adolescent, adolescent and young adults from three Indian states: Madhya Pradesh, Jharkhand and Chhattisgarh. β-globin positive 2034 samples were employed for HPV detection and genotyping. Results The overall prevalence of HPV infection in tribal girls was 12.9% (262/2034). More than 65% (172/262) of them were infected with HR-HPV types of which HPV16 was the most predominant type (54%). Young adult girls aged 18–25 years showed a significantly higher prevalence of HPV infection (19.2%; OR = 3.36; 95% CI 2.97–6.34, P<0.001) as compared to that in adolescent (11.4%; OR = 1.82; 95% CI 1.20–2.76, P<0.01) or pre-adolescent girls (6.6%). Conclusion This is a first study showing significantly a very high prevalence of HPV infection in adolescent and young adult tribal girls possibly due to different socio-sexual behavior, indicating a serious health concern for Indian tribal women.

Full Text Available Abstract Background Age at menarche is considered a reliable prognostic factor for idiopathic scoliosis and varies in different geographic latitudes. Adolescent idiopathic scoliosis prevalence has also been reported to be different in various latitudes and demonstrates higher values in northern countries. A study on epidemiological reports from the literature was conducted to investigate a possible association between prevalence of adolescent idiopathic scoliosis and age at menarche among normal girls in various geographic latitudes. An attempt is also made to implicate a possible role of melatonin in the above association. Material-methods 20 peer-reviewed published papers reporting adolescent idiopathic scoliosis prevalence and 33 peer-reviewed papers reporting age at menarche in normal girls from most geographic areas of the northern hemisphere were retrieved from the literature. The geographic latitude of each centre where a particular study was originated was documented. The statistical analysis included regression of the adolescent idiopathic scoliosis prevalence and age at menarche by latitude. Results The regression of prevalence of adolescent idiopathic scoliosis and age at menarche by latitude is statistically significant (p Conclusion Late age at menarche is parallel with higher prevalence of adolescent idiopathic scoliosis. Pubarche appears later in girls that live in northern latitudes and thus prolongs the period of spine vulnerability while other pre-existing or aetiological factors are contributing to the development of adolescent idiopathic scoliosis. A possible role of geography in the pathogenesis of idiopathic scoliosis is discussed, as it appears that latitude which differentiates the sunlight influences melatonin secretion and modifies age at menarche, which is associated to the prevalence of idiopathic scoliosis.

In Germany, smoking prevalence among adolescents has significantly declined since the early 2000s. However, data show that adolescent smoking rates considerably differ between different types of secondary schools. The aim of our study was to examine how educational inequalities in adolescent smoking behaviour have developed over time. Data were used from four population-based studies (each consisting of repeated cross-sectional surveys from 2001-2015): the representative surveys of the Federal Centre for Health Education, the German Health Interview and Examination Survey for Children and Adolescents, the Health Behaviour in School-aged Children Study, and the European School Survey Project on Alcohol and Other Drugs. Each study comprised different age groups (within the age range of 11-17 years) and used different smoking measures. Adolescents' educational status was based on the attended type of secondary school. Absolute and relative educational inequalities were presented as prevalence differences and prevalence ratios, respectively. Despite methodical differences, all four studies similarly reveal that adolescent smoking rates have significantly declined in all educational groups. However, lower smoking rates among secondary school students attending higher educational tracks could be observed. While absolute educational inequalities tended to decrease over time, relative inequalities between educational groups remained rather stable or even increased. Declining adolescent smoking rates suggest that smoking may have lost some of its attractiveness for young people. Our findings further emphasize the importance of tobacco control measures such as raising cigarette taxes, smoking bans, and increasing minimum legal age for tobacco purchase. As relative educational inequalities in adolescent smoking rates did not diminish over time, setting- and target group-specific interventions should focus more on students in middle and lower secondary school tracks.

Emotional and behavioural problems are key health issues in adolescence. The aim of this study was to evaluate the prevalence of emotional and behavioural problems in Chinese school adolescents and to explore associated factors. This cross-sectional study was conducted during the period of November/December 2009. A questionnaire including the Strengths and Difficulties Questionnaire (SDQ) self-reported version, and the characteristics of child (age, gender, only child and study pressure), parents (parent-adolescent relationship and parental expectations) and families (living area, family structure, socio-economic status and negative life events) was distributed to our study population. A total of 5220 Chinese adolescents (aged 11-18) from 30 public schools in Liaoning province completed the questionnaire. Multivariate logistic analysis was used to explore the factors associated with emotional and behavioural problems. The average problem score was 11.28 (SD = 5.86) and the 10.7% scored above the cut-off for emotional and behavioural problems. Factors that increased the risk of having emotional and behavioural problems were: poor parent-adolescent relationship, experiencing more negative life events, older age, having study pressure, living in rural areas, boys and lower parental expectations. The prevalence of emotional and behavioural problems among Chinese adolescents was lower level compared with those reported in other countries. We found parent-adolescent relationship, negative life events and age to be the strongest contributing factors of emotional and behavioural problems. © 2013 John Wiley & Sons Ltd.

Prevalence, change, and correlates of adolescent Internet addiction were examined in this study on the basis of six waves of longitudinal data collected over 6 years. DESIGN, SETTING, PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES: Over 6 years, students responded to a questionnaire containing measures of sociodemographic characteristics, positive youth development, family processes, and Internet addiction behavior. The prevalence rates of Internet addiction in Hong Kong adolescents ranged from 17% to 26.8% during the high school years. Male students consistently showed a higher prevalence rate of Internet addiction and more Internet addictive behaviors than did female students. Longitudinal data suggested that although family economic disadvantage served as a risk factor for youth Internet addiction, the effects of family intactness and family functioning were not significant. Students' overall positive youth development and general positive youth development qualities were negatively related to Internet addictive behaviors and prosocial attributes had a positive relationship with youth Internet addiction. The results suggest that promotion of positive youth development is a promising direction for preventing Internet addiction in Hong Kong adolescents. Gender and family economic disadvantage must be considered in design of the related prevention programs. Copyright © 2016 North American Society for Pediatric and Adolescent Gynecology.

BACKGROUND Acne is a common disease in adolescents, but there are no epidemiological data for acne in Brazil. OBJECTIVES To estimate the prevalence and degree of acne in adolescents from Sao Paulo and study socio-demographic factors, family history and lifestyle, associated with the disease. METHODS Cross-sectional study with 452 adolescents aged between 10 and 17 (mean=13.3 years), students from elementary and high school, examined by 3 independent evaluators. RESULTS 62.4% were female, 85.8% white and 6.4% were aged 14. The prevalence was 96.0% and increased with age - all students over 14 had acne. The most prevalent form of acne was comedonal (61.1%), followed by mild (30.6%) and moderate (7.6%) papular-pustular, which affected mostly the face (97.5%). About half of the adolescents reported family history for acne in mother or father, and 20.6% reported previous treatment for acne. There was a higher chance of presenting non-comedonal acne with increased age (pacne in adolescents varies widely due to the clinical features and diagnostic methods used. Adolescents whose brothers/sisters had acne (OR=1.7-p=0.027) and those over 13 (OR=8.3-pacne. CONCLUSION This study showed high prevalence of acne in adolescents from Sao Paulo, predominantly the comedonal form on the face, with a higher chance of presenting non-comedonal acne with increased age.

Full Text Available Abstract Background Body weight is highly associated with overall health status. Being severely thin or obese may impose the risk of many health problems. Early detection of body mass index (BMI status may help to reduce the associated comorbidities. Although many studies in the literature have investigated the BMI of school adolescents in Malaysia, the data on status of body weight among school adolescents in suburban states like Terengganu is limited. This study aimed to describe the body weight status of the whole population of school adolescents in all seven districts in Terengganu, Malaysia. Methods Using a cross-sectional study design, body weight and height were measured, and BMI was calculated and classified using WHO BMI-for-age Z-score. Data was obtained using the National Fitness Standard (SEGAK assessment, which was uploaded in a specific Health Monitoring System (HEMS. Results From a total of 62,567 school adolescents, 50.7% were boys and 49.3% were girls. Girls had significantly higher BMI than boys in age groups of 13 to 15 and 16 to 17 years old. Among boys and girls, there were significant differences in mean BMI of school adolescents between rural and urban school locations in all age groups (p < 0.001. There were also significant differences in BMI between boys and girls in all districts in Terengganu, except Kemaman and Kuala Terengganu, for all age groups (p < 0.001. Overall, the prevalence of thinness, normal, overweight and obesity were 8.4, 64.6, 15.0 and 12.0%, respectively. There were significant differences between BMI categories and genders in total participants, and within rural and urban school locations (p < 0.05. In all districts except Marang and Dungun, significant difference was also found between BMI categories and genders. Conclusion The prevalence of thinness, overweight and obesity in Terengganu were substantial. In this study, BMI category was associated with gender, age, school location and

Abstract The major infectious diseases in Chile encompass the periodontal diseases, with a combined prevalence that rises up to 90% of the population. Thus, the population-based surveillance of periodontal diseases plays a central role for assessing their prevalence and for planning, implementing, and evaluating preventive and control programs. Self-report questionnaires have been proposed for the surveillance of periodontal diseases in adult populations world-wide. Objective This study aimed to develop and assess the content validity and reliability of a cognitively adapted self-report questionnaire designed for surveillance of gingivitis in adolescents. Material and Methods Ten predetermined self-report questions evaluating early signs and symptoms of gingivitis were preliminary assessed by a panel of clinical experts. Eight questions were selected and cognitively tested in 20 adolescents aged 12 to 18 years from Santiago de Chile. The questionnaire was then conducted and answered by 178 Chilean adolescents. Internal consistency was measured using the Cronbach’s alpha and temporal stability was calculated using the Kappa-index. Results A reliable final self-report questionnaire consisting of 5 questions was obtained, with a total Cronbach’s alpha of 0.73 and a Kappa-index ranging from 0.41 to 0.77 between the different questions. Conclusions The proposed questionnaire is reliable, with an acceptable internal consistency and a temporal stability from moderate to substantial, and it is promising for estimating the prevalence of gingivitis in adolescents.

Stimulants are recommended as a first-line treatment for attention- deficit/hyperactivity disorder (ADHD); however, a subset of the patient population augments their stimulant treatment with other medications. The objective of this study was to estimate the 1 year period prevalence of concomitant psychotropic medication use among children and adolescents with ADHD during 2009. Patients 6-17 years of age with one or more primary ADHD diagnoses between July 1, 2008 and December 31, 2009 and one or more stimulant prescription fills during 2009 were identified from a large United States commercial claims database. Concomitant psychotropic medication use, defined as 30 days of continuous medication supply overlap between the augmenting agent and stimulant, was evaluated for 14 distinct psychotropic medication categories (6 with a United States Food and Drug Administration (FDA) approved indication for ADHD, 8 without an indication for ADHD). The 1 year period prevalence of concomitant psychotropic medication use (both overall and within each medication category) was calculated and compared between patients with and without psychiatric or neurologic comorbidities. Children (6-12 years) and adolescents (13-17 years) were evaluated separately. A total of 71,201 children and 49,959 adolescents met the inclusion criteria. The 1 year period prevalence of concomitant psychotropic medication use among children and adolescents was 20.3% and 23.4%, with 5.7% and 6.7% augmenting with two or more medication categories, respectively. The most common concomitant medication categories were selective serotonin reuptake inhibitors (SSRIs) (children: 6.2%; adolescents: 11.4%), atypical antipsychotics (5.8%; 6.8%) and clonidine immediate release (5.4%; 2.9%). Children and adolescents with psychiatric or neurologic comorbidities had higher rates of augmentation than did those without comorbidities (all p<0.001). This epidemiologic study found that the prevalence of concomitant psychotropic

There is currently a debate about whether frequent use of these media might have adverse effects on health, especially on headaches, which are among the most-reported health complaints in adolescents. The aim of the present study was to assess associations between frequent use of electronic media and the prevalence of different types of headache in adolescents. Methods Data were derived from a population-based sample (n = 1,025, ages 13-17 years. Type of headache (i.e. migraine, tension-type headache, unclassifiable headache was ascertained by standardized questionnaires for subjects reporting headache episodes at least once per month during the last six months. Duration of electronic media use was assessed during personal interviews. Associations were estimated with logistic regression models adjusted for age group, sex, family condition and socio-economic status. Results Most of the adolescents used computers (85%, watched television (90% or listened to music (90% daily, otherwise only 23% of the participants used their mobile phones and only 25% played with game consoles on a daily basis. A statistically significant association between listening to music and any headache (odds ratio 1.8; 95% confidence interval 1.1-3.1 for 30 minutes per day, 2.1; 1.2-3.7 for 1 to 2 hours per day; 2.0; 1.2-3.5 for 3 hours and longer listening to music per day was observed. When stratifying for type of headache, no statistically significant association was seen. Conclusions Apart from an association between listening to music on a daily basis and overall headache, no consistent associations between the use of electronic media and different types of headache were observed.

To assess the period prevalence and severity of dizziness and vertigo in adolescents. In 1661 students in 8th-10th grade in twelve grammar schools in Munich, Germany information on vertigo/dizziness was assessed by a questionnaire in the class room setting. Three month prevalence of dizziness/vertigo was estimated; symptoms were categorized as orthostatic dizziness, spinning vertigo, swaying vertigo or unspecified dizziness. Duration of symptoms and impact on daily life activities were assessed. 72.0% (95%-CI = [69.8-74.2]; N = 1196) of the students (mean age 14.5±1.1) reported to suffer from at least one episode of dizziness or vertigo in the last three months. Most adolescents ticked to have symptoms of orthostatic dizziness (52.0%, 95%-CI = [49.5-54.4], N = 863). The period prevalence for the other types of vertigo were spinning vertigo: 11.6%, 95%-CI = [10.1-13.3], N = 193; swaying vertigo: 12.2%, 95%-CI = [10.6-13.8], N = 202; and unspecified dizziness: 15.2%, 95%-CI = [13.5-17.1], N = 253. About 50% of students with spinning vertigo and swaying vertigo also report to have orthostatic dizziness. Most vertigo/dizziness types were confined to less than one minute on average. The proportion of students with any dizziness/vertigo accounting for failure attending school, leisure activities or obliging them to stay in bed were more pronounced for spinning or swaying vertigo. Dizziness and vertigo in grammar school students appear to be as common as in adults. In face of the high period prevalence and clinical relevance of dizziness/vertigo in adolescents there is a need for prevention strategies. Risk factors for dizziness/vertigo need to be assessed to allow for conception of an intervention programme.

Because of the increased risks associated with unplanned pregnancy for males and females with congenital heart disease (CHD), we investigated sexual intercourse and contraception use in these adolescents and young adults (AYA) and compared the same with national and state population data. We recruited 337 AYA with structural CHD aged 15-25 years (Mage = 19 years, standard deviation = 3.1; 53% male, 84% white) from an outpatient cardiology clinic to participate in a larger study assessing genetic knowledge and health behaviors. Cumulative lifetime prevalence of adolescent (aged 15-18 years) sexual intercourse was compared with the 2011 Youth Risk Behavior Surveillance System and the 2007 Ohio Youth Risk Behavior Survey. Cumulative lifetime prevalence of young adult (aged 19-25 years) sexual intercourse and contraception use at last sex were compared with the 2006-2008 National Survey of Family Growth. Reported rates of ever having sexual intercourse, 26% of adolescents and 74% of young adults with CHD, were significantly lower than general population rates (47% and 86% respectively; p contraception at last intercourse, whereas 25% used dual effective methods and 23% used no effective method. Lower rates of ever having sexual intercourse in this population suggest that the psychosexual development of AYA with CHD may lag behind their peers. As nearly one in four participants reported using no effective method of contraception, health care providers should increase discussions of contraception with males and females with CHD.

Despite anti-smoking prevention programs, many adolescents start smoking at school age. The main objectives of this study were to determine the prevalence and risk factors associated with smoking in adolescents living in Uruguaiana, RS, Brazil. A prospective study was conducted in adolescents (12-19 years), enrolled in municipal schools, who answered a self-administered questionnaire on smoking. 798 adolescents were enrolled in the study, with equal distribution between genders. The tobacco experimentation frequency (ever tried a cigarette, even one or two puffs) was 29.3%; 14.5% started smoking before 12 years of age and 13.0% reported smoking at least one cigarette/day last month. Having a smoking friend (OR: 5.67, 95% CI: 2.06-7.09), having cigarettes offered by friends (OR: 4.21, 95% CI: 2.46-5.76) and having easy access to cigarettes (OR: 3.82, 95% CI: 1.22-5.41) was identified as factors associated with smoking. Having parental guidance on smoking (OR: 0.67, 95% CI: 0.45-0.77), having no contact with cigarettes at home in the last week (OR: 0.51, 95% CI: 0.11-0.79) and knowing about the dangers of electronic cigarettes (OR: 0.88, 95% CI: 0.21-0.92) were identified as protection factors. The prevalence of smoking among adolescents in Uruguaiana is high. The implementation of measures to reduce/stop tobacco use and its new forms of consumption, such as electronic cigarettes and hookah, are urgent and imperative in schools.

The few epidemiological studies on asthma and allergic diseases performed in Africa have shown that the prevalence of these diseases is high or increasing. No such studies have been performed in Angola. To determine the prevalence of asthma and other allergic diseases in Angolan adolescents. This was a descriptive, observational, cross-sectional study in the province of Luanda, Angola, using the International Study of Asthma and Allergies in Childhood study methodology in adolescents aged 13 and 14 years. Twenty-three (12%) public schools were randomly selected. Data were analysed using the Statistical Package for the Social Sciences version 22.0 software. A total of 3128 adolescents were included. The prevalence of asthma (wheezing in the previous 12 months) was 13.4%. The prevalence of rhinitis (sneezing, runny or blocked nose in the previous 12 months) was 27% and that of eczema (itchy skin lesions in the previous 12 months) was 20%; both were more prevalent in girls. Rhinitis was associated with a greater number of episodes of night cough in adolescents with asthma. Rhinitis and eczema, a split-type air conditioning system, and frequent intake (more than once per month) of paracetamol were associated with a higher risk of having asthma. Asthma and related allergic diseases are a public health problem in adolescents from Luanda. Preventive and control measures should be implemented.

Adolescents with psychiatric conditions may be at risk for xerostomia. In this preliminary study, we estimated xerostomia prevalence in adolescents ages 9 to 17 years from an inpatient psychiatric clinic (N = 25) and examined whether: (1) gender and age were associated with xerostomia and (2) xerostomia was associated with self-reported cavities. We used a modified 11-item Xerostomia Index to identify xerostomia (no/yes) and asked if adolescents ever had or currently have cavities (no/yes). The mean age was 14 years (SD = 2.3) and 72% were male. Sixty percent reported xerostomia (SD = 50). There were no significant associations between xerostomia and gender (p = 0.99) or age (p = 0.66), or between xerostomia and past (p = 0.26) or current cavities (p = 0.11). Larger proportions of adolescents with xerostomia reported previous and current cavities. Sixty percent of adolescents from an inpatient psychiatric clinic reported having xerostomia, which may lead to increased caries risk over time. Additional research should examine the prevalence and consequences of xerostomia in high-risk adolescents. © 2015 Special Care Dentistry Association and Wiley Periodicals, Inc.

To describe the prevalence of anemia in Mexican children and adolescents from ENSANUT 2012. Data had the power to make distinctions at the national, regional and rural/urban dwelling. Hemoglobin was measured by Hemocue. Descriptions were made by adjusted frequencies and 95%CI. Confounders were tested in a logistic regression models. The prevalence of anemia in 2012 was: in children 1-4 y, 23.3%; 5-11y, 10.1%, and 12-19 y, 5.6%. The prevalence in female adolescents was 7.7% and 3.6% in males. Reductions in the prevalence of anemia from 1999 was 8.3pp in <5y, 5.1pp in children 5-11y and 3.6pp from 2006 in adolescents. Despite the decrease in the prevalence of anemia in children 1-4 y in the last 13 years, it still is of great concern. There is a need of awareness among social and medical communities about this, to extend the distribution of micronutrient supplements in children <3y, and to promote nutritional education to incentive mothers to provide foods rich in iron.

The aim of this study was to analyze the prevalence and association of barriers to physical activity among adolescents. This cross-sectional study evaluated a representative sample of public high school students in Curitiba-PR, Brazil. A total of 1,609 school adolescents (59.7% male) between 14 and 18 years of age answered a questionnaire on physical activity status and barriers to physical activity. Logistic regressions were conducted for each barrier investigated to verify the association between the prevalence of barriers and physical activity, adjusting for confounding variables (age and socioeconomic status). Analyses were done separately for boys and girls. Only 22% of boys and 9% of girls achieved the current physical activity recommendation. Among the 12 barriers investigated, only "there is nobody to take" did not differ between boys and girls. The perception of barriers was higher for girls than boys (p barriers. "Lack of friends company" and "feel lazy" were the barriers most often reported by boys (30.4%) and girls (51.8%) respectively; however, the barrier most strongly associated with prevalence of physical inactivity was "prefer to do other things" for both boys (OR = 5.02 (2.69 - 9.37); p barriers for the practice of physical activity were more prevalent in girls and differed as to the extent of importance between genders.

With psychopathology rising during adolescence and evidence suggesting that adult mental health burden is often due to disorders beginning in youth, it is important to investigate the epidemiology of adolescent mental disorders. We analysed data gathered at ages 11 (baseline) and 19 years from the population-based Dutch TRacking Adolescents' Individual Lives Survey (TRAILS) study. At baseline we administered the Achenbach measures (Child Behavior Checklist, Youth Self-Report) and at age 19 years the World Health Organization's Composite International Diagnostic Interview version 3.0 (CIDI 3.0) to 1584 youths. Lifetime, 12-month and 30-day prevalences of any CIDI-DSM-IV disorder were 45, 31 and 15%, respectively. Half were severe. Anxiety disorders were the most common but the least severe whereas mood and behaviour disorders were less prevalent but more severe. Disorders persisted, mostly by recurrence in mood disorders and chronicity in anxiety disorders. Median onset age varied substantially across disorders. Having one disorder increased subjects' risk of developing another disorder. We found substantial homotypic and heterotypic continuity. Baseline problems predicted the development of diagnosable disorders in adolescence. Non-intact families and low maternal education predicted externalizing disorders. Most morbidity concentrated in 5-10% of the sample, experiencing 34-55% of all severe lifetime disorders. At late adolescence, 22% of youths have experienced a severe episode and 23% only mild episodes. This psychopathology is rather persistent, mostly due to recurrence, showing both monotypic and heterotypic continuity, with family context affecting particularly externalizing disorders. High problem levels at age 11 years are modest precursors of incident adolescent disorders. The burden of mental illness concentrates in 5-10% of the adolescent population.

Full Text Available Objective. The aim of this study was to find out the prevalence of overweight and obesity among adolescents in seven Arab countries using similar reference standard. Methods. A school-based cross-sectional study was carried out in seven cities in Arab countries, namely, Algeria, Jordan, Kuwait, Libya, Palestine, Syria, and United Arab Emirates. A multistage stratified random sampling technique was used. The total sample included was 4698 adolescents aged from 15 to 18 years (2240 males, 2458 females. The International Obesity Task Force (IOTF reference standard was used to classify the adolescents as nonobese, overweight, and obese. Results. Among males, overweight was highest among Kuwaiti adolescents (25.6%, followed by Jordanian (21.6%, and Syrian (19.7% adolescents. Among females, the highest prevalence of overweight was reported in Libyan adolescents (26.6%, followed by Kuwaiti (20.8%, and Syrian (19.7% adolescents. As for obesity, Kuwaiti adolescents showed the highest prevalence of obesity for both males (34.8% and females (20.6%. Conclusion. There is an urgent need to establish a plan of action to combat obesity in schoolchildren in these countries.

Objective: To investigate the prevalence and trend of overweight and obesity in children and adolescents aged 6-17 years between 2002 and 2012 in Guangdong province. Methods: A total of 7 075 children and adolescents aged 6-17 years were selected in Guangdong for nutritional survey in 2002 and a total of 2 319 children and adolescents aged 6-17 years were selected in nine counties/districts of Guangdong for nutritional survey during 2009-2012 through multi-stage random cluster sampling. The body height and weight of all the children and adolescents were measured. Results: The result of 2009-2012 survey indicated the average prevalence of overweight and obesity in the children and adolescents surveyed were 7.3% and 4.5 %, respectively. The prevalence of overweight and obesity were higher in boys (8.9% and 6.5%) than in girls (5.3% and 2.2%), in rural area (9.3% and 5.6%) than in urban area (4.7% and 3.2%). Children and adolescents aged 9-11 years had a higher overweight and obesity rates compared with other age groups. Compared with 2002, except for obesity rate in urban girls, the prevalence of overweight and obesity in children and adolescents obviously increased. The increase rate was higher in rural area than urban area and in boys than in girls. Conclusions: Compared with 2002, the prevalence of overweight and obesity in children and adolescents in Guangdong obviously increased. The prevalence was much higher in boys, those living in rural area and those aged 9-11 years, thus more attention should be paid to them.

Tobacco smoking is a major risk factor for non-communicable diseases such as ischaemic heart disease, stroke, chronic obstructive airways disease and several cancers. There is little data about the prevalence and determinants of smoking among adolescents in southern Africa. This study aimed to determine the prevalence and determinants of cigarette smoking among adolescents in Blantyre City, Malawi. Cross-sectional data were obtained from school-going adolescents in Blantyre in 2001 using the Global Youth Tobacco Survey data collection instrument. Data were analysed to determine prevalence of current and ever cigarette smoking, and predictors of smoking. The prevalence of current smoking and ever smoking were 3.0% and 15.6%, respectively. Predictors of current tobacco smoking included male gender, having friends or parents who smoked, having been exposed to advertisements about tobacco brands on television and having seen a lot of advertisements in newspapers and magazines. School programmes that included being taught about smoking in class and a class discussion on the dangers of tobacco were not associated with reduced current smoking. Intervention programmes aiming to curb tobacco smoking among adolescents should focus on dealing also with parental smoking, peer influence and pay special attention toward male gender. School-based programmes to prevent smoking should be evaluated as some may have little impact in influencing current smoking status.

Objective Earlier epidemiological studies have shown that headaches are frequent among adolescents, especially girls. In particular, recurrent primary headache disorders such as migraine and tension-type headaches are common complaints in this age group. Headaches are increasingly being recognized as a significant health problem in adolescents and can lead to significant disabilities by affecting their lives, their school performance and their social lives. The aim of this study was to compare the prevalence of primary headaches among adolescents aged 16-20 years in Norway in two periods. Very few replicate studies have re-evaluated the prevalence of primary headaches in this age range and it is uncertain whether the prevalence is increasing. Methods Two cross-sectional, population-based studies were conducted in Norway from 1995 to 1997 (Young-HUNT 1) and from 1999 to 2001 (Young-HUNT 2). In Young-HUNT 1, 2594 adolescents in 2nd and 3rd grade in upper secondary school (aged 16-20 years) completed a comprehensive questionnaire including one question regarding headache during the last 12 months. In addition, 1730 of the students were interviewed about their headache complaints. In Young-HUNT 2, 2373 adolescents aged 16-20 years completed the same questionnaire and 1655 were interviewed in the same way as the earlier survey. The interviews were performed by trained nurses, and respondents were asked if they had experienced recurrent headache during the last year. If so, the headache was classified as migraine (MI), tensiontype headache (TTH) or non-classifiable headache (NCH). Headache frequency during the past year was recorded according to the following categories: Less than 1 day per month (less than monthly), 1-3 days per month (monthly), 1-5 days per week (weekly), or more than 5 days per week (daily). Results The participation rate was 88% in Young-HUNT 1 and 81% in Young-HUNT 2. The overall prevalence of having had headaches during the last 12 months did not

The recent increase in both childhood obesity and adolescent anorexia nervosa in developed countries has underlined the important consequences that these trends may have on public health, as there is an increased risk that these conditions may become chronic diseases in adulthood. Therefore, it is necessary to monitor prevalence rates and trends in thinness and overweight (including obesity) among children and adolescents at different levels: international, national and sub-national. Since 2001/2002, a nutritional surveillance system has been implemented in the Tuscany Region to estimate the nutritional status and lifestyles of children and adolescents. The main objectives were to assess the prevalence of thinness, overweight and obesity among Tuscan children and adolescents and to provide baseline information on the prevalence of thinness, for the first time calculated according to the new international definitions, for geographical comparisons and descriptions of time trends. Independent cross-sectional sample surveys were conducted in 2002, 2004 and 2006 in Tuscany, North-Central Italy. Data were collected from stratified two-stage cluster samples of children aged 9 years (n = 3,048 in 2002 and n = 1,430 in 2006) and of adolescents aged 11-13-15 years (n = 1,066, n = 1185 and n = 1,160 in 2004 and n = 1,189, n = 1,211 and n = 1,178 in 2006, respectively). Weights and heights of primary school children were measured by means of standardized methods, while those of adolescents were self-reported. Decimal age was calculated from the date of birth to the date of measurement. Body Mass Index classes were calculated according to the International Obesity Task Force standards. Instead of the term underweight in children, we used the term thinness, which the World Health Organization uses to mean low Body Mass Index for age in adults and adolescents. According to Cole's recently published cut-offs for thinness, we divided our Body Mass Index values below 18.5 into three

To determine the prevalence of overweight and obesity among children and adolescents in Chennai, India, using national and international age- and sex- specific body mass index (BMI) cut-off points. The Obesity Reduction and Awareness and Screening of Non communicable diseases through Group Education in Children and Adolescents (ORANGE) project is a cross-sectional study carried out on 18,955 children (age 6-11 years) and adolescents (age 12-17 years) across 51 schools (31 private and 20 government) of Chennai. Overweight and obesity was classified by the International Obesity Task Force (IOTF 2000) and Khadilkars criteria (2012), and Hypertension by the IDF criteria (in children ≥10 years and adolescents). The prevalence of overweight/obesity was significantly higher in private compared to government schools both by the IOTF criteria [private schools: 21.4%, government schools: 3.6%, (OR: 7.4, 95% CI:6.3-8.6; POverweight/obesity was higher among girls (IOTF: 18%, Khadilkar: 21.3%) compared to boys (IOTF: 16.2%, Khadilkar: 20.7%) and higher among adolescents (IOTF: 18.1%, Khadilkar: 21.2%) compared to children (IOTF: 15.5%, Khadilkar: 20.7%). Prevalence of hypertension was 20.4% among obese/overweight and 5.2% among non-obese (OR 4.7, 95%CI: 4.2-5.3, Poverweight and obesity is high among private schools in Chennai, and hypertension is also common.

Suicidal behaviour is prevalent among adolescents and is a significant predictor of future suicide attempts (SAs) and suicide death. Data on the prevalence and epidemiological characteristics of suicidal behaviour in Chinese adolescents are limited. This study was aimed to examine the prevalence, characteristics and risk factors of suicidal behaviour, including suicidal thought (ST), suicide plan (SP) and SA, in a large sample of Chinese adolescents. This report represents the first wave data of an ongoing longitudinal study, Shandong Adolescent Behavior and Health Cohort. Participants included 11 831 adolescent students from three counties of Shandong, China. The mean age of participants was 15.0 (s.d. = 1.5) and 51% were boys. In November-December 2015, participants completed a structured adolescent health questionnaire, including ST, SP and SA, characteristics of most recent SA, demographics, substance use, hopelessness, impulsivity and internalising and externalising behavioural problems. The lifetime and last-year prevalence rates were 17.6 and 10.7% for ST in males, 23.5 and 14.7% for ST in females, 8.9 and 2.9% for SP in males, 10.7 and 3.8% for SP in females, 3.4 and 1.3% for SA in males, and 4.6 and 1.8% for SA in females, respectively. The mean age of first SA was 12-13 years. Stabbing/cutting was the most common method to attempt suicide. Approximately 24% of male attempters and 16% of female attempters were medically treated. More than 70% of attempters had no preparatory action. Female gender, smoking, drinking, internalising and externalising problems, hopelessness, suicidal history of friends and acquaintances, poor family economic status and poor parental relationship were all significantly associated with increased risk of suicidal behaviour. Suicidal behaviour in Chinese adolescents is prevalent but less than that previously reported in Western peers. While females are more likely to attempt suicide, males are more likely to use lethal methods

The prevalence of mental health problems among children and adolescents is of growing importance. Intervening in children's mental health early in life has been shown to be more effective than trying to resolve these problems when children are older. With respect to prevention activities in community settings, the prevalence of problems should be estimated, and the required level of services should be delivered. The prevalence of children's mental health disorders has been reported for many countries. Preventive intervention has emphasized optimizing the environment. Because parents are the primary influence on their children's development, considerable attention has been placed on the development of parent training to strengthen parenting skills. However, a public-health approach is necessary to confirm that the benefits of parent-training interventions lead to an impact at the societal level. This literature review clarifies that the prevalence of mental health problems is measured at the national level in many countries and that population-level parenting interventions can lower the prevalence of mental health problems among children in the community.

To analyze calcium intake in adolescents according to sociodemographic variables, health-related behaviors, morbidities, and body mass index. This was a cross-sectional population-based study, with a two-stage cluster sampling that used data from a survey conducted in Campinas, São Paulo, Brazil, between 2008 and 2009. Food intake was assessed using a 24-hour dietary recall. The study included 913 adolescents aged 10-19 years. Average nutrient intake was significantly lower in the segment with lower education of the head of the family and lower per capita family income, in individuals from other cities or states, those who consumed fruit less than four times a week, those who did not drink milk daily, those who were smokers, and those who reported the occurrence of headaches and dizziness. Higher mean calcium intake was found in individuals that slept less than seven hours a day. The prevalence of calcium intake below the recommendation was 88.6% (95% CI: 85.4-91.2). The results alert to an insufficient calcium intake and suggest that certain subgroups of adolescents need specific strategies to increase the intake of this nutrient.

This manuscript examined the prevalence and extrinsic risk factors for dental erosion (DE) in early and middle adolescents in Pasto, Colombia. Dental erosion was evaluated in a random sample of 384 individuals aged 10-15 years attending three primary and high schools in this cross-sectional study. Clinical dental assessment for DE was done using O'Sullivan index. Data on general sociodemographic variables and extrinsic risks factors were obtained. Descriptive and univariate binary logistic regression analyses were performed. Dental erosion was observed in 57.3% of individuals. The univariate binary logistic regression analysis showed that frequency of drinking natural fruit juices (OR 2.670, 95% CI 1.346 - 5.295, P=0.004) and their pH (OR 2.303, 95% CI 1.292 - 4.107, P=0.004) were more associated with the odd of DE in early adolescence. However, a high SES (OR 10.360, 95% CI 3.700 - 29.010, P<0.001) and frequency of snacks with artificial lemon taste (OR 3.659, 95% CI 1.506 - 8.891, P=0.003) were highly associated with the risk of DE in middle adolescence. The results suggest that DE is a prevalent condition in adolescents living in a city in southern Colombia. The transition from early to middle adolescence implies new bio-psychosocial changes, which increase the risk for DE.

To determine the prevalence and geographic variations of the symptoms associated with asthma in Galician children and adolescents. A cross-sectional epidemiological study following ISAAC (International Study of Asthma and Allergies in Childhood) methodology, and using a written questionnaire distributed in schools. The study sample included 10,371 6-7 year-old children and 10,372 13-14 year-old adolescents, all of them from Galician Health Areas. A logistic regression model was used to analyse geographic variations. In the 6-7 year-old group, wheezing in the last 12 months varied from 11.4% (Santiago) to 15.7% (Vigo) and in the adolescents varied from 8.8% (Ourense) to 18.8% (Vigo). The distribution by gender showed a predominant significance in 6-7 year-old males (Pchildren and 2.39 (95% CI, 1.82-3.13) for adolescents. The estimated prevalence of asthma in the Autonomous Community of Galicia was 13.6% in younger children and 12.2% in adolescents. The prevalence of wheezing in the last 12 months in the different areas of Galicia is considerably higher than the rest of Spanish ISAAC cities in the 6-7 years group and very similar in the 13-14 years group, except in Vigo where it is considerably higher. We found a clearly defined geographic pattern in the adolescent group, with higher prevalences in coastal areas than in the interior. Copyright © 2010 SEPAR. Published by Elsevier Espana.

Conclusion: Through this study, we found that our statistics matched those of internationally published reports concerning the early age of onset of the disease and its corresponding bilateralism. However, contrary to the international reports, it was evident that this condition was more prevalent among the females in our study sample, and no other associated pathologies were found.

Incidence and prevalence of patellofemoral pain: A systematic review and meta-analysis.

Benjamin E Smith

Full Text Available Patellofemoral pain is considered one of the most common forms of knee pain, affecting adults, adolescents, and physically active populations. Inconsistencies in reported incidence and prevalence exist and in relation to the allocation of healthcare and research funding, there is a clear need to accurately understand the epidemiology of patellofemoral pain.An electronic database search was conducted, as well as grey literature databases, from inception to June 2017. Two authors independently selected studies, extracted data and appraised methodological quality. If heterogeneous, data were analysed descriptively. Where studies were homogeneous, data were pooled through a meta-analysis.23 studies were included. Annual prevalence for patellofemoral pain in the general population was reported as 22.7%, and adolescents as 28.9%. Incidence rates in military recruits ranged from 9.7-571.4/1,000 person-years, amateur runners in the general population at 1080.5/1,000 person-years and adolescents amateur athletes 5.1%-14.9% over 1 season. One study reported point prevalence within military populations as 13.5%. The pooled estimate for point prevalence in adolescents was 7.2% (95% Confidence Interval: 6.3%-8.3%, and in female only adolescent athletes was 22.7% (95% Confidence Interval 17.4%-28.0%.This review demonstrates high incidence and prevalence levels for patellofemoral pain. Within the context of this, and poor long term prognosis and high disability levels, PFP should be an urgent research priority.CRD42016038870.

Morey, Carolyn

2008-01-01

BACKGROUND: Deliberate self harm is major public health problem, in particular among young people. Although several studies have addressed the prevalence of deliberate self harm among young people in the community, little is known about the extent to which deliberate self harm comes to the attention of medical services, the self harm methods used and the underlying motives. The aim of this study was to determine the prevalence of deliberate self harm in adolescents and the methods, motives and help seeking behaviour associated with this behaviour. METHODS: A cross-sectional survey using an anonymous self-report questionnaire was administered in 39 schools in the Southern area of the Health Service Executive, Ireland. Of the 4,583 adolescents aged 15-17 years who were invited to participate in the survey, 3,881 adolescents took part (response: 85%). RESULTS: A lifetime history of DSH was reported by 9.1% (n = 333) of the adolescents. DSH was more common among females (13.9%) than males (4.3%). Self cutting (66.0%) and overdose (35.2%) were the most common DSH methods. A minority of participants accessed medical services after engaging in DSH (15.3%). CONCLUSION: DSH is a significant problem in Irish adolescents and the vast majority do not come to the attention of health services. Innovative solutions for prevention and intervention are required to tackle DSH in adolescents.

In industrialized countries atopic diseases have been reported to be less likely in children and adolescents with a migrant background compared to non-migrants. This paper aimed at both examining and comparing prevalence of asthma, allergic rhinoconjunctivitis and atopic dermatitis and allergic sensitization to specific IgE antibodies in children and adolescents with and without a migrant background. Using data of the population-based German Health Interview and Examination Survey for children and adolescents (KiGGS;n = 17,450; 0-17 years), lifetime and 12-month prevalence of atopic diseases and point prevalence of 20 common allergic sensitizations were investigated among migrants compared to non-migrants. Multiple regression models were used to estimate the association of atopic disease and allergic sensitization with migrant background. In multivariate analyses with substantial adjustment we found atopic dermatitis about one-third less often (OR 0.73, 0.57-0.93) in participants with a two-sided migrant background. Statistically significant associations between allergic sensitizations and a two-sided migrant background remained for birch (OR 0.73, 0.58-0.90), soybean (OR 0.72, 0.54-0.96), peanut (OR 0.69, 0.53-0.90), rice (OR 0.64, 0.48-0.87), potato (OR 0.64, 0.48-0.85), and horse dander (OR 0.58, 0.40-0.85). Environmental factors and living conditions might be responsible for the observed differences.

Dysmenorrhea is commonly categorized into two types; primary and secondary. Primary dysmenorrhea (PD) is the focus of this review. PD is defined as painful menses with cramping sensation in the lower abdomen that is often accompanied by other symptoms, such as sweating, headache, nausea, vomiting, diarrhea, and tremulousness. All these symptoms occur just before or during the menses in women with normal pelvic anatomy. In adolescents the prevalence of PD varies between 16% and 93%, with severe pain perceived in 2% to 29% of the studied girls. Several studies suggest that severe menstrual pain is associated with absenteeism from school or work and limitation of other daily activities. One-third to one-half of females with PD are missing school or work at least once per cycle, and more frequently in 5% to 14% of them. The wide variation in the prevalence rates may be attributed to the use of selected groups of subjects. Many risk factors are associated with increased severity of dysmenorrhea including earlier age at menarche, long menstrual periods, heavy menstrual flow, smoking and positive family history. Young women using oral contraceptive pills (OCP) report less severe dysmenorrhea. The considerably high prevalence of dysmenorrhea among adolescents verified that this condition is a significant public health problem that requires great attention. SUMMARY OF MAIN RESULTS: Many methodological problems are encountered during quantifying and grading severity of pain related to dysmenorrhea. Quantifying and assessment tools depend on women's self-reporting with potential bias. There is a scarcity of longitudinal studies on the natural history of dysmenorrhea as well as the possible effects of many modifiable risk factors. In addition, the duration of follow-up in the available studies is relatively short. Therefore, several aspects are still open for research. Medical treatment for dysmenorrhea includes anti-inflammatory drugs (NSAIDs), OCP or surgical intervention

Head injuries are the main cause of death in bicycle-related accidents among children and adolescents. According to a Cochrane Review, the risk of head injury (OR 0.31; 95% CI 0.26-0.37) or brain injury (OR 0.31; 95% CI 0.23-0.42) decreases by 69% if a helmet is worn. This study presents the prevalence of helmet use in cycling children and adolescents in Germany and the proportion of head injuries that could be prevented by wearing helmets. The potential effects of increased helmet wearing rates on the population attributable risk percentage for head injuries (PAR%) are demonstrated. The prevalence of helmet use in children aged 3-17 years was analysed using data from the German Health Interview and Examination Survey for Children and Adolescents (KiGGS). The percentage of head injuries preventable by helmet use in this group is estimated by calculating PAR%. Prevalence rates of helmet use and odds ratios from a Cochrane Review about the effectiveness of bicycle helmets for the prevention of head injuries were used for analysis. The potential effect of increased helmet use is shown in 3 scenarios by means of differences of PAR% values in the most relevant age groups. The older the children, the less likely they are to wear a helmet: 89.5% (95% CI 88.0%-90.8%) of the 3- to 6-year-old children wear a helmet when cycling but only 11.0% (95% CI 9.3%-12.9%) of 14- to 17-year-old adolescents do. In the youngest group (3-6 years) 19% of bicycle-related head injuries are attributable to the non-use of helmets, but this proportion rises to 67% in the oldest group (14-17 years). The PAR% of head injuries associated with not wearing a helmet may be reduced by more than a third by increasing the helmet wearing rate to 67% (2 out of 3) among adolescents, and may be reduced to half if 75% of adolescents wore a helmet. Particularly older children and adolescents hardly use bicycle helmets, hence the rate of preventable head injury is high. Efforts towards increasing helmet use

Full Text Available Abstract Background Non-suicidal self-injury (NSSI is a proposed new “condition for further study” in the DSM-5. To date no prevalence data has been available on this diagnostic entity from a representative sample of the general population. Methods A representative sample of the German population (N = 2509, mean age = 48.8 years, SD = 18.1, female 55.4 % completed the NSSI section of the German version of the Self-Injurious Thoughts and Behaviors Interview (SITBI-G. Results A history of NSSI at least once during lifetime was reported by 3.1 % of all participants, with higher lifetime prevalence rates in younger age groups. DSM-5 NSSI disorder criteria were met by 0.3 %. The most common function of NSSI was automatic negative reinforcement (e.g. to alleviate negative feelings. Conclusions To the best of our knowledge, this is the first study reporting rates for the proposed NSSI category in DSM-5 from a representative sample of the general population. In comparison to findings from community samples of adolescents, adults seem to have lower lifetime prevalence rates of NSSI, thus making it necessary to emphasize prevention and treatment efforts in younger age groups.

The aim of this study was to determine the prevalence of dissociative identity disorder (DID) and other dissociative disorders among adolescent psychiatric outpatients. A total of 116 consecutive outpatients between 11 and 17 years of age who were admitted to the child and adolescent psychiatry clinic of a university hospital for the 1st time were evaluated using the Adolescent Dissociative Experiences Scale, adolescent version of the Child Symptom Inventory-4, Childhood Trauma Questionnaire, and McMaster Family Assessment Device. All patients were invited for an interview with the Structured Clinical Interview for DSM-IV Dissociative Disorders (SCID-D) administered by 2 senior psychiatrists in a blind fashion. There was excellent interrater reliability between the 2 clinicians on SCID-D diagnoses and scores. Among 73 participants, 33 (45.2%) had a dissociative disorder: 12 (16.4%) had DID, and 21 (28.8%) had dissociative disorder not otherwise specified. There was no difference in gender distribution, childhood trauma, or family dysfunction scores between the dissociative and nondissociative groups. Childhood emotional abuse and family dysfunction correlated with self-reported dissociation. Of the dissociative adolescents, 93.9% had an additional psychiatric disorder. Among them, only separation anxiety disorder was significantly more prevalent than in controls. Although originally designed for adults, the SCID-D is promising for diagnosing dissociative disorders in adolescents, its modest congruence with self-rated dissociation and lack of relationship between diagnosis and childhood trauma and family dysfunction suggest that the prevalence rates obtained with this instrument originally designed for adults must be replicated. The introduction of diagnostic criteria for adolescent DID in revised versions of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, would refine the assessment of dissociative disorders in this age group.

There are wide-ranging differences in human growth, not only between ethnic groups but also between regions. Shandong is one of the most populous provinces in China, with inequalities of regional economic status. However, no studies on the differences in development among children and adolescents in different districts have been reported. This study assessed the differences in height, weight and prevalence of obesity among children and adolescents of different socioeconomic status (SES) districts in Shandong, China. Data for this study were obtained from a large cross-sectional survey of schoolchildren. A total of 42 286 students (21 222 boys and 21 064 girls) aged 7-18 years from 16 districts participated in this study. Height and weight of all subjects were measured and BMI was calculated from their height and weight. Prevalence rates of obesity and overweight were determined by comparing calculated BMIs (kg/m(2)) to International Obesity Task Force (IOTF) cut-offs. Each of the 16 districts was assigned an SES ranking (low, moderate, high) based on per capita GDP and income in urban and rural areas. Comparisons of height, weight and the prevalence of overweight and obesity among different groups were made. Significant differences between SES groups were observed for height, weight and the prevalence of overweight and obesity. Boys and girls from high SES group were taller, heavier and more likely to be obese than their peers from moderate and low SES groups. The prevalences of combined overweight and obesity in the three SES groups were 18.46%, 21.08% and 27.31% in boys and 10.43%, 12.42% and 15.18% in girls, respectively. There have been obvious regional variations in development and the prevalence of obesity in children and adolescents in Shandong, China, These variations in development and prevalence of obesity in children and adolescents among different SES districts being related to the local SES, process of urbanization, living environments, nutritional

Full Text Available Background: In the last twenty years a marked rise in overweight and obesity among children and adolescents in developed countries was observed. Obesity in this age group is a significant risk factor for type 2 diabetes and cardiovascular diseases in adulthood. So far no comparative data on overweight and obesity in Slovene children and adolescents existed. In our study the data collected during preventive examinations of five-year-old and adolescents was analysed and guidelines for management of children with high body mass index (BMI were proposed.Methods: Using the methods of descriptional statistics the data on BMI of 4685 randomly collected five-year-old children and 2474 randomly collected adolescents aged 15–16 years were analysed. Data was collected in the years 2003–2005, evaluated according to the international reference values, and compared to other populations.Results: The prevalence of overweight among five-year-old children is 18.4% and 20.9% in boys and girls respectively. The obesity criteria are fulfilled in 9.0% boys and 7.9% girls. Among adolescents 17.1% boys and 15.4% girls are overweight and 6.2% boys and 3.8% girls are obese. These results indicate that the prevalence of obesity in Slovenia is similar as in other developed European countries.Conclusions: The study showed that obesity in childhood and adolescence in Slovenia is a problem that deserves more concern in medical institutions and on national level. Further research on reasons for this condition and new programs for stimulation of physical activity and healthy nutrition of children and adolescents are warranted.

Psychiatric disorders, including conduct disturbances, substance abuse, and affective disorders, emerge in approximately 20% of adolescents. In parallel with the rise in internet use, the prevalence of depression among adolescents has increased. It remains unclear whether and how internet use impacts mental health in adolescents. We assess the association between patterns of internet use and two mental health outcomes (depression and anxiety) in a healthy adolescent population. A total of 126 adolescents between the ages of 12 and 15 years were recruited. Participants reported their typical computer and internet usage patterns. At baseline and one-year follow-up, they completed the Beck Depression Index for primary care (BDI-PC) and the Beck Anxiety Inventory for Primary Care (BAI-PC). Individual linear regressions were completed to determine the association between markers of internet use at baseline and mental health outcomes at one-year follow-up. All models controlled for age, gender, and ethnicity. There was an inverse correlation between minutes spent on a favorite website per visit and BAI-PC score. No association was found between internet use and BDI-PC score. There is no relationship between internet use patterns and depression in adolescents, whereas internet use may mitigate anxiety in adolescents with higher levels of baseline anxiety. ©Robyn Pauline Thom, David S Bickham, Michael Rich.

Resultados: A prevalência de insatisfação com a IC foi de 60,4% (masculino = 54,5%, feminino = 65,7%; p OBJECTIVE: To investigate the prevalence of body image (BI dissatisfaction in adolescents. The study enrolled 641 adolescents aged 11 to 17 from the town of Saudades, Santa Catarina, Brazil. The prevalence of BI dissatisfaction was 60.4% (males = 54.5%, females = 65.7%; p < 0.05. Boys were more likely to wish to increase the size of their body silhouette (26.4% while girls wished to reduce theirs (52.4%. Adolescents from urban areas manifested greater prevalence of BI dissatisfaction and were more likely to want to reduce their body silhouette. The reasons given by these adolescents for why they were dissatisfied with their body images were similar for both sexes (p = 0.156. When analyzed by neighborhood the urban adolescents said that their dissatisfaction was esthetic, whereas the rural adolescents said it was based on self-esteem. An association was detected between perceived BI and the reasons for dissatisfaction. Conclusions: Esthetics, self-esteem and health were the most common reasons for BI dissatisfaction among these adolescents. More than half of them were dissatisfied with their body silhouettes. Therefore, there is a need for interventions by health services and professionals in this age range in order to avoid possible future problems with eating disorders (anorexia, bulimia and vigorexia.

Full Text Available Background: Metabolic syndrome (MetS, a cluster of cardiovascular risk factors, is one of the most common metabolic disorders, which lead to many chronic diseases. The link between childhood MetS and occurrence of atherosclerosis and its sequels in adulthood is well documented. This study aims to systematically review the prevalence of MetS among Iranian children and adolescents. Materials and Methods: An electronic search was conducted on studies published from January 1990 to January 2015. The main international electronic data sources were PubMed and the NLM Gateway (for MEDLINE, Institute of Scientific Information (ISI, and SCOPUS. For Persian databases, we used domestic databases. We included all available population-based studies and national surveys conducted in the pediatric age group aged 3–21-year-old. Results: In this review, 2138 articles were identified (PubMed: 265; SCOPUS: 368; ISI: 465; Scientific Information Database: 189; IranMedex: 851; Irandoc: 46. After quality assessment, 13 qualified articles were evaluated. The number of total population and points of data were 24,772 and 125, respectively. Regarding the geographical distribution, we found 2 national, 6 provincial, and 5 district level points of data. The prevalence range of MetS among children was 1–22% using different definitions. Reported range of pediatric MetS defined by different criteria was as follows: National Cholesterol Education Program-Adult Treatment Panel III; 3–16%, International Diabetes Federation; 0–8%, American Heart Association; 4–9.5%, The National Health and Nutrition Examination Survey III; 1–18%, de Ferranti; 0–22%. Conclusion: MetS is a common metabolic disorder among Iranian children and adolescents, with increasing trends during the last decades. This finding provides baseline useful information for health policy makers to implement evidence based-health promotion for appropriate controlling of this growing health problem for the

There is limited research on sexually transmitted infections (STIs) among adolescents in Korea. The objective of this study was to explore the prevalence of and risk factors for STIs among Korean adolescents under probation. A cross-sectional analysis was conducted in one juvenile-delinquent center and five probation offices in Korea to determine the prevalence of STIs caused by the following pathogens: Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis, herpes simplex virus (HSV), human immunodeficiency virus (HIV), Treponema pallidum, Mycoplasma hominis, Mycoplasma genitalium, Ureaplasma urealyticum, and Ureaplasma parvum. Of the 237 (208 male and 29 female) participating adolescents, 152 (64.1%) had a history of coitus. Overall, 133 (56.1%) subjects tested positive for at least one microorganism in their genitourinary tract. The most prevalent pathogen was U. urealyticum (24.7%, n = 65), followed by U. parvum (24.1%, n = 57), M. hominis (17.3%, n = 41), C. trachomatis (13.9%, n = 33), N. gonorrhoeae (1.7%, n = 4), T. vaginalis (0.8%, n = 2), and HSV (0.8%, n = 2). The prevalence of syphilis was 0.8% (n = 2). There were no reported cases of HIV infection. Fifty-four participants (35.5%) were positive with more than two pathogens. We did not find any significant difference between STIs and socioeconomic factors, behavioral factors or sexual practices. In conclusion, the prevalence of STIs among adolescents under probation was high. Systematic screening programs, more practical sexual education, and adequate provision of treatment are essential for the prevention and management of STIs among adolescents, especially those under probation.

Full Text Available Background: Hypertension is a chronic condition of concern due to its role in the causation of coronary heart disease, stroke and other  complications. It is one of the major risk factors for cardio-vascular mortality accounting for 20-50% of all deaths. Children with higher blood pressure tend to maintain those levels during adulthood also. Objectives:  Assess the prevalence of hypertension in adolescents (11-18 years, its risk factors and their socio-demographic co-relates. Material and Method:  Prevalence of adolescent hypertension in previous studies was 7% and the sample size accordingly came to be 1314 with a relative precision of 20%. Multistage sampling technique was used. Half each of the sample size was covered in urban and rural areas . Households in the selected colonies in the urban areas and villages were randomly selected and the adolescents interviewed and examined. Their responses were recorded on a pretested questionnaire and results drawn. Data were analysed using Epi-info and SPSS and chi-square test applied. Results:   Prevalence of adolescent hypertension was found to be 5.3% (72 out of 1340; significantly associated with type of family (P<0.001, educational status (P<0.001, occupation (P<0.001, BMI (P<0.01, and smoking habit (P<0.05. However, no relationship of hypertension was found with salt intake, type of diet, exercise, alcohol consumption, stress and family history of hypertension. Conclusion: Socio-demographic factors certainly influence the prevalence and probability of occurrence of adolescent hypertension but the effect of established risk factors (for adult hypertension needs to be further evaluated for adolescent hypertension and more studies are required in this area.

Much is known about the prevalence and correlates of dating violence, especially the perpetration of physical dating violence, among older adolescents. However, relatively little is known about the prevalence and correlates of the perpetration of cyber dating abuse, particularly among early adolescents. In this study, using a predominantly ethnic-minority sample of sixth graders who reported ever having had a boyfriend/girlfriend (n = 424, 44.2 % female), almost 15 % reported perpetrating cyber dating abuse at least once during their lifetime. Furthermore, using a cross-sectional design, across multiple levels of the socio-ecological model, the individual-level factors of (a) norms for violence for boys against girls, (b) having a current boyfriend/girlfriend, and (c) participation in bullying perpetration were correlates of the perpetration of cyber dating abuse. Collectively, the findings suggest that dating violence interventions targeting these particular correlates in early adolescents are warranted. Future studies are needed to establish causation and to further investigate the relative importance of correlates of the perpetration of cyber dating abuse among early adolescents that have been reported among older adolescents.

To investigate the incidence and prevalence of developmental odontogenic cysts in children and adolescents and compare the features of the two most common types, dentigerous cyst and keratocystic odontogenic tumor (KCOT). A retrospective review in a series of 369 patients with all histological diagnoses of developmental odontogenic cysts in children (≤12 years) and adolescents (13-18 years) was conducted. Among these, 361 (97.8%) patients were diagnosed as dentigerous cyst (n = 281) and KCOT (n = 80), with the male-to-female ratios of dentigerous cyst and KCOT both being 2:1. The average age of the patients with KCOT was older than that of those with dentigerous cyst (14.7 years vs 11.8 years, p < 0.001). Dentigerous cyst (59.1%) was more common in children, but KCOT (78.8%) was more common in adolescents (p < 0.001). Dentigerous cyst (57.6%) predominantly located on the maxilla, but KCOT (60.3%) predominantly located on the mandible (p = 0.010). Adolescent patients with lesions located on the mandible would favor KCOT over dentigerous cyst. This study aids in better knowledge of the prevalence of developmental odontogenic cysts in a large pediatric population, and shows that a well-supported early diagnosis is indispensable for a more adequate treatment.

Full Text Available Background : Adolescence is one of the most critical growth periods in the human's life. Eating disorder is one of the most common nutritional-psychological disorders in this period, which can lead to acute and chronic physical and mental problems. Therefore, regarding the importance of the topic, the present study was designed to determine the prevalence of weight – controlling attitude and eating disorders, and their association with anthropometric indices in female adolescent school students. Materials and Methods: The present study was a cross-sectional descriptive analytical study. 594 high school adolescent girls were selected using multi-stage random sampling method. Nutritional attitude was assessed by use of a nutritional attitude questionnaire. Another specific questionnaire was used to gather demographic and anthropometric information. Data analysis was done using SPSS software, independent t- test and Chi-square (P˂0.05. Results: The information shows that 80% of the studied population are at risk of eating disorders. The number of the obese , over weight and underweight students were significantly more in the group with nutritional attitude disorders. Conclusion: Due to the high prevalence of eating disorders in adolescent girls, and the concomitant obesity and underweight with these disorders, the correction of these attitude could be mentioned as a health priority in this city

Introduction The aims of this study were to assess the prevalence of dental caries and the DMFT index, as well as the distribution pattern of pit and fissure sealants on permanent teeth in a Portuguese sample of adolescents, and to assess whether the existing usage of sealants and socio-demographic factors are correlated to caries prevalence on the examined sample. Materials and Methods A cross-sectional study was designed with a sample of 447 adolescents aged 12 to 18 years old, attending a public school in Sátão, Portugal. A self-administered questionnaire with questions about oral health behaviours and socio-economic status was answered by adolescents in the classroom. Clinical examination of oral health status and assessment of fissure sealants were accomplished by only one trained member of the research team. Results We obtained a DMFT index of 3.32 (2.92), which indicates a moderate level of prevalence of dental caries. When considering a DMFT = 0, we found significant statistical differences between the parents´ level of education (≤ 4th grade = 26.3 vs 5th–12th grade = 18.8 vs Portuguese adolescents. The establishment of a more targeted preventive program with better and more effective oral health education is essential, having into account socio-demographic aspects. PMID:25803849

Full Text Available Adolescent sexuality is a relevant public health issue, as it affects risk to contract HIV and other sexually transmitted infections. The assessment of prevalence of sexual intercourse among adolescents may guide policies and programmes aimed at reducing the transmission of sexually transmitted infections among this age group. Using data from the Thailand Global School-Based Student Health Survey (GSHS 2008, we assessed the prevalence of sexual intercourse in the last 12 months and its associated factors among adolescents (=2758. Overall the prevalence of sexual intercourse in the past 12 months was 11.0% (14.6% males and 7.6% females. Variables positively associated with the outcome in multivariable analysis were male gender (OR=1.66; 95% CI 1.14–242, older age, ≥15 years (OR=2.60, 1.80–3.74, current alcohol use (OR=2.22, 1.46–3.36, psychosocial distress (OR=2.11, 1.44–3.09 and among females current smoking (OR=5.47, 1.62–18.48, lifetime drug use (AOR=4.35, 1.04–18.3 and lack of parental or guardian bonding (AOR=0.51, 0.27–0.97. Efforts to control unhealthy lifestyles (substance use and psychosocial distress may impact on adolescents' sexual activity.

The aim of this study was to determine the prevalence of headache in adolescents and its association with excessive use of electronic devices and games. The sample comprised 954 adolescents of both sexes (14 to 19 years) who answered a questionnaire about use of computers and electronic games, presence of headache and physical activity. The binary and multinomial logistic regression, with significance level of 5% was used for inferential analysis. The prevalence of headache was 80.6%. The excessive use of electronics devices proved to be a risk factor (OR = 1.21) for headache. Subjects aged between 14 and 16 years were less likely to report headache (OR = 0.64). Regarding classification, 17.9% of adolescents had tension-type headache, 19.3% had migraine and 43.4% other types of headache. The adolescents aged form 14 to 16 years had lower chance (OR ≤ 0.68) to report the tension-type headache and other types of headache. The excessive use of digital equipment, electronic games and attending the third year of high school proved to be risk factors for migraine-type development (OR ≥ 1.84). There was a high prevalence of headache in adolescents and high-time use of electronic devices. We observed an association between excessive use of electronic devices and the presence of headache, and this habit is considered a risk factor, especially for the development of migraine-type.

Evidence is mixed as to whether meeting sexual partners online ('internet-partners') is associated with risky sexual behaviour and/or sexually transmitted infection transmission. Accordingly, we sought to estimate the prevalence of reporting various online romantic and sexual activities among Norwegian adolescents, including internet-partners, and the reason for meeting them and to examine differences in sexual behaviour, partnership characteristics and chlamydia infection prevalence among those reporting internet-partners versus those reporting only offline partners. Population-based cross-sectional survey among sexually experienced girls and boys, 15-20 years, using electronic questionnaires and collecting urine samples for Chlamydia trachomatis PCR testing (79% provided both, n=1023). We used logistic regression to examine associations, adjusting for potentially confounding variables. Overall, 30% of both genders reported internet-partners (ever). Boys (but not girls) with internet-partners had higher chlamydia prevalence than those reporting meeting sexual partners only offline (8.1%, 95% CI 4.3% to 13.7% vs 1.6%, 0.5% to 3.7%). Two-thirds of girls and 37% of boys reported meeting their most recent internet-partner to start a romantic relationship, while the remainder did so with the specific intention of having sex. Among both genders, reporting sexual (vs romantic) reasons for meeting their most recent internet-partners was associated with reporting several risky sexual behaviours, including multiple recent sex partners (adjusted OR girls: 3.27, boys: 2.48) and three-fold higher chlamydia prevalence. This population-based study suggests that internet-partners are common among adolescents in Norway, and the reason for meeting them was more strongly associated with additionally reporting sexual risk behaviours and prevalent chlamydia infection than the internet itself as a meeting venue.

To assess the prevalence of type 2 diabetes mellitus (T2DM) and maturity onset diabetes of the young (MODY) in children and adolescents aged 0-20 yr in Baden-Württemberg (BW), Germany, and to compare our results with those from other European countries. Our study involved every children's hospital (n = 31), each diabetologist in private practice (n = 122), and every internal medicine unit (n = 164) in BW. A written questionnaire and a telephone survey were used to identify children with T2DM and MODY who had been examined at any of these institutions between 2004 and 2005. Population data were drawn from the national census of 1987 and the subsequent annual updates. The prevalence of T2DM for the age range from 0 to 20 yr is 2.30/100 000, whereas the prevalence of MODY in the same age range is 2.39/100 000. The median age of patients with T2DM was 15.8 yr, and 13.9 yr for MODY patients. The majority of patients with either T2DM or MODY were treated in children's hospitals and by consultant diabetologists. A molecular genetic analysis was done to substantiate the clinical diagnosis in less than half of the recruits (14.3% of T2DM and 44.8% of MODY patients). The prevalence of T2DM and MODY is considerably lower than the prevalence of type 1 diabetes. Type 2 diabetes thus continues to be a rare disease in children and adolescents in Germany, as is also the case in other European countries.

Full Text Available Objectives: To estimate the prevalence of obsessive-compulsive symptoms (OCS and disorder (OCD among adolescents and to describe OCD characteristics according to gender. Methods: Participants were selected by cluster sampling at seven high-schools in southern Brazil. In the first stage, 2,323 students were screened for OCS; in the second stage, adolescents scoring ≥ 21 on the OCI-R scale were individually interviewed. OCD diagnosis was established using a semi-structured interview (Schedule for Affective Disorders and Schizophrenia for School Aged Children: Present and Lifetime Version - K-SADS-PL. Results: The past-month estimated prevalence of OCS was 18.3%, and the point estimated prevalence of OCD, 3.3%. Girls showed higher scores (OCS: 24.8 vs. 14.4%; OCD: 4.9 vs. 1.4%; p < 0.001. Only 9.3% of OCD adolescents had been diagnosed and 6.7% received treatment. The most frequent/severe DY-BOCS dimensions were miscellaneous (86.7%; mean score 6.3±3.8 and symmetry (85.3%; 5.9±3.8. Female OCD adolescents predominantly showed depression (p = 0.032, and male adolescents, tic disorders (p = 0.006. Conclusions: OCD is underdiagnosed in adolescents, and few are treated. Future studies should investigate the relationship between OCS and the onset of OCD.

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.

: Gastrointestinal (GI) disorders in early life contribute to a lower quality of life and more persistent GI symptoms during the rest of life. Epidemiologic data on adolescence GI disorders are scarce. We aimed to perform a population-based study to assess the prevalence of GI symptoms in adolescents and their relation to sex, age, and socioeconomic status. : A multistage random sample of Tehran middle and high school students (ages 14-19 years) was selected. A validated Persian version of the Rome II questionnaire was used to measure the frequency of different GI disorders as well as demographic socioeconomic variables. : A total of 1436 participants were enrolled in the study, 736 (51.3%) of whom were men. Mean (SD) age was 16.9 (1.8) years. The frequency of at least 1 GI symptom was 32.4%. The 4 most prevalent GI symptoms were bloating (16.9%), heartburn (4.9%), incontinence (4.3%), and irritable bowel syndrome (4.1%). Bloating, irritable bowel syndrome, and proctalgia fugax were significantly more common in girls (P < 0.05). Incontinence was significantly more prevalent in lower socioeconomic status levels (P = 0.01). In logistic regression, age was a risk factor for abdominal bloating and dysphagea and a protective factor for incontinence. : Our study indicates that GI symptoms are common among adolescents. Girls are more prone to these disorders. Special psychological and medical interventions are necessary for high-risk groups.

Full Text Available Background: One of the main reasons for recent scientific interest in screen-based behaviour (SB is the relationship between SB and risk of being overweight or obese. The primary mechanism for overweight and obesity is an imbalance of energy intake versus energy expenditure and one reason for the interest in SB is its association with reduced energy expenditure relative to other activities. Objective: The aim of this study is to provide a basic overview of the level and structure of SB in Czech adolescents on the basis of age and gender while taking into account the differences between weekday and weekend screen based activities. Methods: Data from the Health Behaviour in School-aged Children (HBSC study conducted in May-June 2010 in the Czech Republic were used. The sample consisted of 4365 Czech pupils (48.5% boys; age 11, n = 1406; age 13, n = 1446; age 15, n = 1513. Binomial logistic regression and Chi-square test of independence were used to provide basic comparison on the basis of gender and age groups. Results: The prevalence of SB rise with growing age with the most visible increase in prevalence is between ages 11 and age 13. SB is significantly more prevalent among adolescent boys compared with adolescent girls. Czech adolescents are more likely to not meet the recommendation of 2 hours for watching TV at weekends compared to weekdays. Playing computer games is more common among boys contrary to chatting online, which is more common among girls. The overall patterns of playing computer games and chatting online during weekends were similar to those at weekdays but increased. Conclusions: Most children in the Czech Republic do not meet the limit for total SB time of 4 or fewer hours while the prevalence of SB rises with growing age and at weekends. Interventions and strategies aiming at reducing SB in children focusing on the family and school environment in the Czech Republic are required.

Abstract Several studies have reported high prevalence of risk factors for cardiovascular disease in adolescents. To perform: i) systematically review the literature on the prevalence of high blood pressure (HBP) in adolescents; ii) analyze the possible methodological factors associated with HBP; and iii) compare the prevalence between developed and developing countries. We revised 10 electronic databases up to August 11, 2013. Only original articles using international diagnosis of HBP were considered. The pooled prevalence's of HBP were estimated by random effects. Meta-regression analysis was used to identify the sources of heterogeneity across studies. Fifty-five studies met the inclusion criteria and total of 122,053 adolescents included. The pooled-prevalence of HBP was 11.2%, 13% for boys, and 9.6% for girls (P < 0.01). Method of measurement of BP and year in which the survey was conducted were associated with heterogeneity in the estimates of HBP among boys. The data indicate that HBP is higher among boys than girls, and that the method of measurement plays an important role in the overall heterogeneity of HBP value distributions, particularly in boys.

This cross-sectional survey of a low socioeconomic patient group was designed to determine the prevalence and severity of parentally perceived behavioral problems in adolescents as well as to investigate the correlation between such problems and single parenting, family communications, and medical care delivered. The sample population consisted of 79 parents and 121 teenagers selected from a family practice center. The medical record and telephone interview were the sources of information. Results include a parental perception of a high prevalence of problems with school grades (48 percent), school attendance (38 percent), and household problems (chores and sibling rivalry). Of low prevalence but high severity were perceived problems related to suicidal ideation, running away, sexual activity, and gang membership. Single-parent homes had a threefold higher incidence of behavioral problems, a greater degree of communication, and a lower use of community resources than two-parent families. None of the approximately 400 perceived behavioral problems listed by parents was found in the family physicians' master problem list. The results indicate the need for physician education of low socioeconomic and single-parent patients with regard to communication and coping style. In addition, it appears that training programs should provide more education in the care of adolescents.

Respiratory symptoms during exercise are common and might limit adolescents' ability to take part in physical activity. To estimate the prevalence, determinants and consequences of exercise-induced dyspnea (EID) on daily life in a general population of 12-13 year old adolescents. A letter was sent to the parents of all 12-13 year old adolescents in the city of Uppsala (n = 3838). Parents were asked to complete a questionnaire together with their child on EID, asthma and allergy, consequences for daily life (wheeze, day time- and nocturnal dyspnea) and physical activity. The response rate was 60% (n = 2309). Fourteen percent (n = 330) reported EID, i.e. had experienced an attack of shortness of breath that occurred after strenuous activity within the last 12 months. Female gender, ever-asthma and rhinitis were independently associated with an increased risk of EID. Ever-asthma was reported by 14.6% (n = 338), and 5.4% (n = 128) had both EID and ever-asthma. Sixty-one percent (n = 202) of the participants with EID did not have a diagnosis of asthma. In addition to rhinitis, participants with EID reported current wheeze and day-time as well as nocturnal dyspnea more often than the group without EID. No difference was found in the level of physical activity between participants with and without EID. Adolescents with undiagnosed exercise-induced dyspnea have respiratory symptoms and are affected in daily life but have the same level of physical activity as adolescents without exercise-induced respiratory symptoms.

Adolescents' leisure activities are increasingly focusing on Internet activities, and today, these coexist with traditional leisure activities such as sport and meeting friends. The purpose of the present study was to investigate leisure activities, particularly Internet activities, among boys and girls with ADHD, and compare these with boys and girls from the general population. The objective was also to explore how traditional leisure activities and Internet activities interrelate among adolescents with ADHD. Adolescents with ADHD (n = 102) were compared with adolescents from the general population on leisure activities and Internet use. Leisure activities among adolescents with ADHD tended to focus on Internet activities, particularly online games. Internet activities were broadening leisure activities among adolescents with ADHD, rather than being a substitute for traditional leisure activities. Internet activities may provide adolescents with ADHD accessible means of social interaction. © The Author(s) 2015.

Depression among adolescents has been recognized as a major public health issue. The objective of this study was to determine the prevalence and correlates of depression among school-going adolescents in Malaysia. Data from the Malaysia Global School-based Health Survey (GSHS) 2012 were analyzed with additional data from the validated DASS21 (Depression, Anxiety, and Stress) questionnaire. The study revealed that 17.7% of respondents had depressive symptoms. Multivariate analysis further showed that feeling lonely (adjusted odds ratio [aOR] = 2.99; 95% CI = 2.57-3.47), Indian ethnicity (aOR = 2.00; 95% CI = 1.63-2.44), using drugs (aOR = 1.85; 95% CI = 1.21-2.82), and being bullied (aOR = 1.79; 95% CI = 1.60-1.99) were significantly associated with depressive symptoms. Lack of parental supervision, alcohol use, and tobacco use were also significant risk factors. Addressing depressive symptoms among adolescents may have implications for managing their risks of being bullied and substance use. This study also highlights the need to further investigate depressive symptoms among adolescents of Indian ethnicity. © 2014 APJPH.

To determine the prevalence of Chlamydia trachomatis, Neisseria gonorrhoeae, and Trichomonas vaginalis infection in sexually active Chilean adolescents and young adults. A comparative analysis was performed between genders to identify demographic, clinical, and sexual behavior characteristics to predict the occurrence of C trachomatis. Analytical observational study. Santiago, Chile. Two hundred eighty-six sexually active volunteers aged 24 years or younger (171 female and 115 male); 82.9% (237/286) of them were classified as having high socioeconomic status. Confidential survey and self-collected samples (urine for men and vaginal swabs for women). Prevalence, demographic characteristics, symptoms, and sexual behavior characteristics. The prevalence rate of C trachomatis was 8.7% (10/115) in men and 8.8% (15/171) in women (P = .58). N gonorrhoeae was detected in 1 subject, whereas no T vaginalis cases were detected. In multivariate analysis, having some college education was protective (odds ratio [OR], 0.28; 95% confidence interval [CI], 0.09-0.89), whereas having a higher number of sexual partners was a risk factor (OR, 1.19; 95% CI, 1.1-1.3) for C trachomatis infection. The latter was also predicted by postcoital bleeding (OR, 4.6; 95% CI, 1.30-16.23) in the female model. C trachomatis infection rates were similar between both genders. Protective characteristics for the occurrence of this infection were having some college education, lower number of sexual partners, and if female, the absence of postcoital bleeding. This study highlights the importance of C trachomatis screening among the Chilean affluent population younger than 25 years. However, further studies are needed in a more diverse and representative sample to recommend universal screening in Chilean adolescents and young adults.

We present guidance on electronic nicotine delivery systems (ENDS) for health care professionals who care for adolescents. ENDS provide users with inhaled nicotine in an aerosolized mist. Popular forms of ENDS include e-cigarettes and vape-pens. ENDS range in disposability, customization, and price. Growth of ENDS usage has been particularly rapid in the adolescent population, surpassing that of conventional cigarettes in 2014. Despite surging use throughout the United States, little is known about the health risks posed by ENDS, especially in the vulnerable adolescent population. These products may potentiate nicotine addiction in adolescents and have been found to contain potentially harmful chemicals. The growth in these products may be driven by relaxed purchasing restrictions for minors, lack of advertising regulations, and youth friendly flavors. Taken together, ENDS represent a new and growing health risk to the adolescent population, one that health care professionals should address with their patients. We suggest a patient centered strategy to incorporate ENDS use into routine substance counseling. Copyright © 2015 Society for Adolescent Health and Medicine. Published by Elsevier Inc.

The prevalence of overweight and obesity in children in Mexico are high, as well as the complications associated with their presence. The objective of this work was to estimate the prevalence of metabolic syndrome in obese children and adolescents attending a Hospital Clinic and identify the associated factors. Cross sectional design with 120 children and adolescents; of either sex, with exogenous obesity and BMI > 2.0 standard deviations. Personal and family history was collected, blood pressure was measured and determination of serum glucose, insulin, lipoprotein HDL cholesterol and triglycerides were performed. The presence of metabolic syndrome with the ATPIII, WHO and International Diabetes Federation criteria was identified. The association of metabolic syndrome with different variables was identified with chi square test and calculation of odds ratio. Mean age was 10.6 ± 2.7 years. The prevalence of metabolic syndrome was 37.5% to 54.5% depending on the criteria used. The presence of metabolic syndrome was associated with a history of large birth weight (OR= 2.21 [1.01-4.82]), and insulin resistance (OR= 6.53 [2.40-18.2]). The prevalence of metabolic syndrome is high in this group of children and adolescents with obesity. The history of large birth weight and the presence of insulin resistance should alert us to the presence of the disease.

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.

To investigate the prevalence of autism spectrum disorder (ASD) and attention-deficit-hyperactivity disorder (ADHD) in a population-based group of children and adolescents with Down syndrome, and to relate the findings to level of intellectual disability and to medical conditions. From a population-based cohort of 60 children and adolescents with Down syndrome, 41 individuals (29 males, 12 females; mean age 11y, age range 5-17y) for whom parents gave consent for participation were clinically assessed with regard to ASD and ADHD. The main instruments used were the Autism Diagnostic Interview-Revised, Autism Diagnostic Observation Schedule, Swanson, Nolan, and Pelham-IV Rating Scale, and the Adaptive Behavior Assessment System-II. High rates of ASD and ADHD were found: 17 (42%) and 14 (34%) of the 41 children met DSM criteria for ASD and ADHD respectively. Children with Down syndrome and coexisting neurodevelopmental/neuropsychiatric disorders in addition to intellectual disability and medical disorders constitute a severely disabled group. Based on the results, we suggest that screening is implemented for both ASD and ADHD, at the age of 3 to 5 years and early school years respectively, to make adequate interventions possible. © 2016 Mac Keith Press.

South America is now at a stage of epidemiological transition, changing the condition of high prevalence of underweight and stunting, to a scene marked by increases in obesity that accompanies chronic diseases, such us cardiovascular disease, diabetes and cancer. Surveillance of risk factors associated with them is considered a priority. To establish the prevalence of risk factors associated with cardiovascular disease in adolescents in public and private schools in the city of Salta, and observe the socioeconomic characteristics and presence of cardiovascular risk factors in parents. Cross-sectional design, adolescents aged 16 to 20 years of public and private schools. Anthropometric, biochemical, food, social, lifestyle and family history variables. Adolescents of private schools had higher average values of cholesterol, LDL and glucose. The prevalence of overweight and obesity in public schools was 15% and 14.2% in private, and of hypertension 11.3% and 12.2%, respectively. It was noted higher consumption of sweets, sodas and juices; 35.1% and 42.5% of adolescents in public and private schools, did not perform physical activity, 14.2% and 27.1% smoked and 66.2% and 54.7%, respectively, consumed alcohol at weekend. The prevalence of obesity in mothers of public school students was significantly higher. There is evidence of the emergence of risk factors associated with cardiovascular disease in adolescents with different characteristics as belonging to public or private schools, but both groups involved in an unhealthy family environment.

Full Text Available Background: Currently, there is a well-publicised worldwide increase in obese patients. The origins of adult obesity, in the majority of cases, are in children. Objective: Our aim was to study the prevalence and gender features of excess weight and obesity in adolescents in Perm. Methods: The study included adolescents aged 13–14, living in the city of Perm. Medical examinations were compared in statistics from 2005 and 2013. Weight, height and waist circumference were measured on all children. Body mass index was calculated, as was a standard deviation coefficient. Sexual development was evaluated according to the criteria of Tanner. Results: 828 adolescents were viewed (444 in 2005 and 384 in 2013. The prevalence of overweight adolescents in 2005 was 12.5%, including 3.1% who were obese. In 2013, 20.3% of adolescents were diagnosed as overweight, with 5.5% being diagnosed as obese. Abdominal obesity to type was diagnosed in 52.4% of obese children. Over the past 8 years, the number of adolescents who are overweight and obese has increased by more than half. A statistically significant increase has beenrecorded for overweight adolescents (ᵪ2 = 5,16; p = 0,023. In adolescents with excess body weight, growth rates were higher than in those children with either normal body weight or obesity; these differences were statistically significant in boys (p = 0.016.

Full Text Available After the worldwide steep increase in child and adolescent overweight and obesity during the last decades, there is now evidence of a levelling off in the prevalence in many countries in the Western world.To examine whether there still is a plateau in the prevalence of overweight and obesity in Danish children and adolescents, or whether the prevalence is decreasing or rising again.THE TRENDS IN THE PREVALENCE RATES WERE BASED ON THREE DATA SETS PROVIDING COMPARABLE REPEATED ESTIMATES: 1 the Danish Health Visitors Child Health Database (DHVCHD with measurements on infant and childhood height and weight from 2002 to 2011 (n up to 39,984, 2 the Danish National Birth Cohort (DNBC with maternal reports of measured infant and childhood height and weight from 1998 to 2010 (n up to 56,826 and 3 the Danish part of the Health Behaviour in School-aged Children survey (HBSC with self-reported information on adolescent height and weight from the years 2002 to 2010 (n = 16,557. Overweight and obesity were categorized according to WHO growth standards. Trends were assessed by repeated point estimates and linear regression analyses providing regression coefficients for changes in per cent per year with 95% confidence intervals (CI.The prevalence rates of overweight and obesity for infants, children and adolescents showed a mixed pattern of decline, stability and increase (ranging from -1.10 through 0.29 per cent per year with CI's from -3.10 through 2.37. Overall, there were no consistent statistically significant trends upwards or downwards, although some significant downward trends in childhood and adolescence were observed.This study, based on data from 1998 through 2011, showed that the prevalence rates of overweight and obesity among Danish infants, children and adolescents were largely still on a plateau with tendencies for a decline among children and adolescents.

Full Text Available Suicide is recognised as the third leading cause of death among adolescents globally. There is however limited data on the prevalence and factors associated with suicide particularly in Ghana. To explore the prevalence and risk and protective factors associated with suicide in Ghana, a nationwide Global School-based Student Health Survey data collected among senior high school adolescents in Ghana was used. The prevalence of suicidal behaviours was 18.2%, 22.5% and 22.2% for suicidal ideation, suicidal plan and suicidal attempt respectively. In the final analysis, anxiety increases the odds of suicidal behaviour, even after controlling for other variables. Loneliness increases the odds of suicidal behaviour but after adjusting for other factors the odds remained for only suicidal plan. Being bullied, physically attacked, involved in a physical fight and food insecurity remained risk factors for suicidal behaviour (i.e. ideation, plan and attempt after adjusting for other factors. Truancy was found as a risk factor for both suicidal ideation and plans but such effect diminished for suicidal plan after adjusting for other variables. Increasing number of close friends remained a risk factor for both suicidal plan and attempt but such effect diminished for suicidal ideation after adjusting for other variables. Parental understanding of adolescents’ problems and worries remained a significant protective factor for all the indices of suicidal behaviour after adjusting for other variables. Parental respect for privacy was protective of suicidal attempt but was not significant after adjusting for other variables. Early identification and intervention for at-risk adolescents in senior high schools, for example those experiencing different forms of physical abuse, drug and substance use and hunger can potentially reduce the prevalence of suicide among this population in Ghana.

Full Text Available We aimed to conduct a review to investigate the prevalence of anxiety disorders among Iranian children and adolescents.We systematically reviewed the literature up to June 2014. We searched three Persian databases (Magiran, IranMedex and SID and three English databases: PubMed, Scopus and PsycINFO. All original studies that investigated the current prevalence of anxiety in a sample of Iranian children and adolescents were entered into the study. All studies conducted on special samples or in special settings were excluded. By searching English databases, we obtained 124 original studies. After removing duplicate papers, 120 articles remained. In the next step, we screened the articles based on their title. In sum, 95 Persian and English articles had relevant titles. After screening based on the abstract and full text, 26 studies remained. After screening based on the full text, all selected studies were qualitatively assessed by two evaluators separately.Twenty five studies were eligible and reported different types of anxiety disorders (i.e., generalized anxiety, separation anxiety, obsessive-compulsive disorder, phobias and panic disorder. The samples varied from 81 to 2996 among studies and their age range was 5 to 18 years. These studies were conducted in different cities of Iran. SCL-90 is a frequently used questionnaire. All anxiety disorders were mostly investigated with the prevalence rates ranging from 6.8% in Saravan to 85% in Bandar Abbas. OCD was the second common study with prevalence rates ranging from 1% in Tabriz to 11.9% in Gorgan.Our findings revealed considerable amount of anxiety disorder among Iranian children and adolescents. Given the fact that anxiety disorder has negative effects on the well-being and function of individuals and can lead to severe problems, this disorder should be considered in mental health programs designed for children and adolescents.

Despite the large number of adolescents of East Asian origin in Canada, there is limited research on sexual health among this population. A first step to develop strategies for sexual health promotion for adolescents is to document the prevalence of sexual behaviours. This study thus estimated the prevalence of sexual health and risk behaviours among East Asian adolescents in grades 7 to 12, using the province-wide, school-based 2008 British Columbia Adolescent Health Survey (unweighted N = 4...

Full Text Available Abstract Background Prevalence of depressive disorders among adolescents has varied across studies. The present study aims to assess current and lifetime prevalence and characteristics of adolescent Major Depressive Disorder (MDD, Dysthymia and Depression NOS among adolescents in Central Norway in addition to socio-demographics and use of mental health care. Method In the Youth and Mental Health Study a representative sample of 2432 junior high school students (mean age 14.9 years, SD = 0.6 from two counties in Central Norway were screened with the Mood and Feelings Questionnaire (MFQ. A subset of 345 of these adolescents (72.5% girls, 220 high scorers (MFQ = > 26, 74 middle scorers (MFQ 7-25, and 50 low scorers (MFQ Results Almost one in four subjects (23% had life-time depression. Prevalences of current Major Depressive Disorder (MDD, Dysthymia and "Double depression" were 2.6%, 1.0% and 0.6%, respectively, and for Depression NOS 6.3%. All depressive disorders were characterized by long duration of episodes with large variations, and for any depressive disorder onset before 12 years of age. In multivariate analyses MDD and Dysthymia were most strongly associated with gender and not living with both biological parents. There was no gender difference for Depression NOS. Although a considerable number of depressed subjects had received mental health care, the reason for contact with services was seldom due to affective symptoms. Less than 20% had been in contact with specialist mental health services. Conclusion High rates of Depression NOS, early onset of depressive episodes, long duration, and low use of specialized services point to the need for improved diagnostic assessment and treatment for young individuals.

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.

Migraine is the most important cause of headache leading to a decrease in the quality of life in children and adolescents. The prevalence of episodic (EM) and chronic migraine (CM) increases with increasing age, which especially focused in recent years. To evaluate the prevalence and determinants of migraine in children and adolescents, we performed this school-based epidemiological study. First part of the study was performed in 2001 that included 5562 children. Second part of the study was performed in 2007 in adolescents including 1155 young. After the main reports published, we made a new analysis in the database that focused on migraine. Totally, 10.4% of the children, predominantly the girls, received the diagnosis of migraine when they grew older (1.7% CM, 8.6% EM). CM frequency increased with increasing ages (doubled at 12 years, P = 0.035). The significant risk factors for having CM were found to be age, gender, and father and sibling headache histories. Most of the clinical characteristics of migraine are far from classical knowledge in children with CM. In adolescents, 18.6% were diagnosed as migraine (1.5%CM, 17.1%EM) with a predominance of girls without age difference. When they reached puberty after 6 years, double the number of cases with CM was headache free. Most of the young changed their headache characteristics during the follow-up period independent from management strategies. Our results showed that CM is an important cause of headache in both children and adolescents with some defining headache characteristics and risk factors concentrated in different age-groups. © 2012 The Author(s) European Journal of Neurology © 2012 EFNS.

The aim of the present study was to gain insight into the prevalence of depression and its association with self-esteem, family, peer and school factors in a large-scale representative Taiwanese adolescent population. A total of 12,210 adolescent students were recruited into the present study. Subjects with a score >28 on the Center for Epidemiological Studies' Depression Scale were defined as having significant depression; the Rosenberg Self-Esteem Scale, Adolescent Family and Social Life Questionnaire and Family C-APGAR Index were applied to assess subjects' self-esteem, family, peer and school factors. The association between depression and correlates were examined on t-test and chi(2) test. The significant factors were further included in logistic regression analysis. Among 9586 participants (response rate: 86.3%), the prevalence of depression was 12.3%. The risk factors associated with depression in univariate analysis included female gender, older age, residency in urban areas, lower self-esteem, disruptive parental marriage, low family income, family conflict, poorer family function, less satisfaction with peer relationships, less connectedness to school, and poor academic performance. After adjusting the effects of sex, age and location, only subjects with lower self-esteem, higher family conflict, poorer family function, lower rank and decreased satisfaction in their peer group, and less connectedness to school were prone to depression on logistic regression. The prevalence of depression is high in Taiwanese adolescents, and the multiple factors of family, peer, school and individuals are associated with adolescent depression. The factors identified in the present study may be helpful when designing and implementing preventive intervention programs.

Full Text Available Abstract Background This study describes the prevalence of dementia and major dementia subtypes in Spanish elderly. Methods We identified screening surveys, both published and unpublished, in Spanish populations, which fulfilled specific quality criteria and targeted prevalence of dementia in populations aged 70 years and above. Surveys covering 13 geographically different populations were selected (prevalence period: 1990-2008. Authors of original surveys provided methodological details of their studies through a systematic questionnaire and also raw age-specific data. Prevalence data were compared using direct adjustment and logistic regression. Results The reanalyzed study population (aged 70 year and above was composed of Central and North-Eastern Spanish sub-populations obtained from 9 surveys and totaled 12,232 persons and 1,194 cases of dementia (707 of Alzheimer's disease, 238 of vascular dementia. Results showed high variation in age- and sex-specific prevalence across studies. The reanalyzed prevalence of dementia was significantly higher in women; increased with age, particularly for Alzheimer's disease; and displayed a significant geographical variation among men. Prevalence was lowest in surveys reporting participation below 85%, studies referred to urban-mixed populations and populations diagnosed by psychiatrists. Conclusion Prevalence of dementia and Alzheimer's disease in Central and North-Eastern Spain is higher in females, increases with age, and displays considerable geographic variation that may be method-related. People suffering from dementia and Alzheimer's disease in Spain may approach 600,000 and 400,000 respectively. However, existing studies may not be completely appropriate to infer prevalence of dementia and its subtypes in Spain until surveys in Southern Spain are conducted.

Attention deficit/hyperactivity disorder (ADHD), the most common childhood neurobehavioural disorder, can produce a series of negative effects on children, adolescents, and even adults as well as place a serious economic burden on families and society. However, the prevalence of ADHD is not well understood in China. The goal of this study was to estimate the pooled prevalence of ADHD among children and adolescents in China using a systematic review and meta-analysis. A systematic literature search was conducted in PubMed, Web of Science, MEDLINE, CNKI, Wanfang, Weipu and CBM databases, and relevant articles published from inception to March 1, 2016, that provided the prevalence of ADHD among children and adolescents in China were reviewed. The risk of bias in individual studies was assessed using the Risk of Bias Tool for prevalence studies. Pooled-prevalence estimates were calculated with a random-effects model. Sources of heterogeneity were explored using subgroup analyses. Sixty-seven studies with a total of 275,502 individuals were included in this study. The overall pooled-prevalence of ADHD among children and adolescents in China was 6.26% (95% CI: 5.36-7.22%) with significant heterogeneity (I 2  = 99.0%, P China is generally consistent with the worldwide prevalence and shows that ADHD affects quite a large number of people under 18 years old. However, a nationwide study is needed to provide more accurate estimations.

Substance Use among Adolescent Mothers: A Review.

Maternal substance abuse is a critical problem, and adolescent mothers appear to be at high risk for such behaviors. We review studies on postpartum adolescent substance use to explore the extent of this problem and avenues for new research. Authors screened 1,300 studies, identifying 12 articles on substance use among postpartum adolescent mothers for this review. Adolescent mothers reported greater substance use before pregnancy compared to other adolescent females. Although some adolescents continued substance use during pregnancy, most stopped using only to resume within six months after birth. Comparisons of use to national samples of nulliparous adolescent females showed a higher prevalence of substance use in this population. Substances used often varied by race/ethnicity, with white mothers more likely to smoke cigarettes and use marijuana, and Black mothers more likely than whites to drink and use drugs. Of all identified studies, only one focused on Hispanics. Beliefs about drug use grew less negative as girls transitioned from pregnancy to parenthood. As they transitioned to adulthood, substance use remained prevalent and stable. Psychological distress and low self-esteem appeared to influence continued use. Friends' cigarette smoking predicted early initiation of and persistent smoking, while increased education predicted quitting. Early initiation of substances often predicted problem behaviors. Adolescent mothers are a vulnerable population, implicating use of problem behavior theory or the self-medication hypothesis in future research. Multiple avenues for new studies are needed to help identify effective treatment and intervention for this understudied population.

Few studies have investigated the prevalence and correlates of risk factors for noncommunicable diseases among Brazilian adolescents. We evaluated the clustering of risk factors and their associations with sociodemographic variables. We used a cross-sectional study carried out in 2011 comprising 1132 students aged 14-19 years from Santa Maria, Brazil. The cluster index was created as the sum of the risk factors. For the correlates analysis, a multinomial logistic regression was used. Furthermore, the observed/expected ratio was calculated. Prevalence of individual risk factors studied was as follows: 85.8% unhealthy diets, 53.5% physical inactivity, 31.3% elevated blood pressure, 23.9% overweight, 22.3% excessive drinking alcohol, and 8.6% smoking. Only 2.8% of the adolescents did not present any risk factor, while 21.7%, 40.9%, 23.1%, and 11.5% presented 1, 2, 3, and 4 or more risk factors, respectively. The most prevalent combination was between unhealthy diets and physical inactivity (observed/expected ratio =1.32; 95% CI: 1.16-1.49). Clustering of risk factors was directly associated with age and inversely associated with socioeconomic status. Clustering of risk factors for noncommunicable diseases is high in Brazilian adolescents. Preventive strategies are more likely to be successful if focusing on multiple risk factors, instead of a single one.

To study the prevalence, distribution and severity of dental erosion among 16-year-old adolescents in the Troms region of Norway. Study design: The participants were recruited through the Tromsø-study ("Fit Futures"), and 392 16-year-olds were examined for dental erosion using clinical intraoral photographs. Three calibrated clinicians used the Visual Erosion Dental Examination (VEDE) system to register and grade the dental erosive wear. More than one third (38%) of the participants showed dental erosion on at least one tooth surface, 18% were limited to the enamel, while 20% of the adolescents showed erosive wear extending into the dentine. The occlusal surfaces of the lower first molars, and the palatal surfaces of the maxillary incisors were the most often and most severely affected. Of the participants showing dental erosion, 93% exhibited "cuppings" on the molars, with 48% limited to the enamel and 52% extending into the dentine. The highest prevalence of "cuppings" (73%) was found on the first lower molars, especially the mesiobuccal cusp of the teeth. The prevalence and severity of dental erosion was found to be higher in male than in female participants (p dental erosion among adolescents in Troms and stress the importance of information, early and effective diagnostics and implementation of prevention strategies.

Determine the prevalence of celiac disease in children and adolescents with type 1 diabetes mellitus (DM1) in attendance in Instituto Estadual de Diabetes e Endocrinologia Luiz Capriglione (IEDE). Blood samples were analyzed in 120 children and adolescents with DM1 from IEDE Diabetes Clinic for the IgA antitissue-transglutaminase antibody and dosage of the seric IgA. Those with positive serology were guided for upper endoscopy with small-bowel biopsy to confirm the celiac disease. The antibody was positive in 3 of the 120 patients. The small-bowel biopsy was confirmatory in all of the positive patients, leading to a prevalence of celiac disease of 2.5% in the studied group. The prevalence of celiac disease is increased in children and adolescents with DM1 when compared with normality. As most are asymptomatic, it is recommended periodical screening of celiac disease in children with DM1.

Smoking represents a public health problem, one which begins during adolescence. The main objective of this study was to analyze the association between smoking and parental and school factors. The study sample consisted of the students from the 20 secondary schools in the region of Osona, Barcelona, Spain. A self-report questionnaire was used to obtain information on the following variables: smoking habit, age of initiation, frequency, type of school (state school or private-subsidized), sex, age, persons living in the home, town, whether the student had lunch at school, whether the student often had lunch or dinner alone at home. A total of 2280 students participated in the study (91%). Mean age was 15.5 years. Of the participants, 20% said they were smokers; 5%, ex-smokers; 34% had tried smoking at least once, and 41% had never smoked. Factors significantly associated with smoking in the multivariate analysis were age, rural town, state school, single parent family, eating alone, and not lunching at school. Smoking prevalence is high among adolescents in our society and there is no gender difference. Our results show that family structure and dynamics can influence smoking in adolescents. Smoking is less prevalent among adolescents who have lunch at school.

Objective: To understand and evaluate the characteristics of geographic distribution of high blood pressure prevalence in children and adolescents aged 7-18 years in China in 2014, and provide evidence for the prevention of hypertension in children and adolescents. Methods: The data of 2014 Chinese National Surveys on Students Constitution and Health conducting 31 provinces (except Hong Kong, Macao and Taiwan) were collected. A total of 216 299 children and adolescents who had complete blood pressure records were selected as study subjects. The low, middle and high prevalence areas were identified according to their high blood pressure detection rates in the children and adolescents,7 % , to analyze the geographic distribution of high blood pressure prevalence in the children and adolescents. The environmental data in the capitals of 31 provinces in 2014 were collected to analyze the correlation between environmental factors and blood pressure Z score in the children and adolescents. Results: The average detection rates of high blood pressure was 6.4 % in 31 provinces (1.5 % -14.2 % ). The high prevalence areas were mainly distributed in the eastern China, especially the Circum-Bohai sea area, low prevalence areas were mainly distributed in the central and western areas of China and some provinces in the east. Correlation analysis results showed that the annual average temperature, annual average air humidity and local altitude were negatively correlated with blood pressure Z score, including diastolic and systolic blood pressure, in both boys and girls. The annual average sunshine time, PM(2.5) and PM(10) concentrations, content of SO(2) were positively correlated with blood pressure Z score in both boys and girls. Conclusions: There was a significant difference in high blood pressure of children and adolescents among 31 provinces. More attention should be paid to the children and adolescents living high prevalence area. And it is necessary to understand

The main aim of the present study is to establish the prevalence of eating disorders (ED) in adolescents of both genders. To our knowledge, such data have not previously been published using both DSM-IV and DSM-III-R criteria. The study sample consisted of 1960 adolescents (1026 girls and 934 boys), 14-15 years of age. The participants completed the Survey for Eating Disorders (SEDs), including DSM-III-R and DSM-IV diagnoses for all subcategories of ED. Lifetime prevalence of any ED among girls was 17.9% anorexia nervosa (AN) 0.7%, bulimia nervosa (BN) 1.2%, binge eating disorder (BED) 1.5%, and EDs not otherwise specified (EDNOS) 14.6%. Corresponding numbers for boys for any ED is 6.5%, AN 0.2%, BN 0.4%, BED 0.9%, and EDNOS 5.0%. Our prevalence rates on AN, BN, and BED largely support previous school/community-based studies, while our figures on EDNOS were rather high. Generally, we found high numbers for boys with ED.

Full Text Available Background: Cigarettes smoking is a common mode of consuming tobacco in India. This habit usually starts in adolescence and tracks across the life course. Interventions like building decision making skills and resisting negative influences are effective in reducing the initiation and level of tobacco use. Aims and Objectives: The purpose of this study was to assess the prevalence of adolescent current cigarette smoking behavior and to investigate the individual and social factors, which influence them both to and not to smoke. Methodology: A cross-sectional study was carried out among school going adolescents in Shimla town of North India. After obtaining their written informed consent, a questionnaire was administered. Results: The overall prevalence of current cigarette smoking was 11.8%. The binary logistic regression model revealed that parents′ and peers′ smoking behavior influence adolescent smoking behavior. Individual self-harm tendency also significantly predicted cigarette smoking behavior. Parental active participation in keeping a track of their children′s free time activities predicted to protect adolescents from taking this habit. Conclusion: Our research lends support to the need for intervention on restricting adolescents from taking up this habit and becoming another tobacco industries′ addicted customer. Parents who smoke should quit this habit, which will not only restore their own health, but also protect their children. All parents should be counseled to carefully observe their children′s free time activities.

From a clinical point of view, the prevalence of allergic contact dermatitis (ACD) among children and adolescents seems to be low. However, many children have dermatitis, most often atopic dermatitis. In selected cases, ACD is suspected, and the child is tested. The question remains, whether...... the prevalence of ACD in children really is low or whether the possibility of ACD is not sufficiently considered. During the last decade, reports have appeared on series of children and adolescents with contact allergy and ACD. Few cases have been reported in infants, but the development of contact allergy...... and ACD increases with age. Most studies include selected groups of children and adolescents with suspected ACD. Few studies have examined unselected populations, and most consider only the prevalence of contact allergy without evaluating the clinical relevance, e.g., the prevalence of ACD. Furthermore...

To establish the prevalence of psychoactive drug consumption in an obese population. We collected data from the clinical records of obese patients attending the Endocrinology and Nutrition Department and Psychiatry Department of Hospital del Mar between June 2005 and May 2006 (n=259). We recorded anthropometric, epidemiological and toxicological data. We also investigated the prevalence of concomitant diseases in this population. Psychoactive drugs were consumed by 37% of obese patients, mainly antidepressants (27%), anxiolytics, sedatives and hypnotics, and anticonvulsants. Moreover, 15% of all patients received combination treatment with two or more psychoactive drugs, mostly the association of an antidepressant and an antiepileptic drug. The prevalence of psychoactive drug consumption in our sample was higher than prevalence data observed in the general population, with antidepressant consumption being three-fold higher.

The prevalence of overweight and obesity has increased among children and adolescents, as well as among adults, and television viewing has been suggested as one cause. Playing digital games (video, computer and console games), or using computer may be other sedentary behaviors related to the development of overweight and obesity. To study the relationships of times spent on viewing television, playing digital games and using computer to overweight among Finnish adolescents. Mailed cross-sectional survey. Nationally representative samples of 14-, 16-, and 18-y-old (N=6515, response rate 70%) in 2001. Overweight and obesity were assessed by body mass index (BMI). The respondents reported times spent daily on viewing television, playing digital games (video, computer and console games) and using computer (for e-mail, writing and surfing). Data on timing of biological maturation, intensity of weekly physical activity and family's socio economic status were taken into account in the statistical analyses. Increased times spent on viewing television and using computer were associated with increased prevalence of overweight (obesity inclusive) among girls: compared to girls viewing television or =4 h daily on viewing television. In girls using computer > or =1 h daily, the OR for being overweight was 1.5 compared to girls using computer games was not associated with overweight. Overweight was associated with using information and communication technology (ICT), but only with certain forms of ICT. Increased use of ICT may be one factor explaining the increased prevalence of overweight and obesity at the population level, at least in girls. Playing digital games was not related to overweight, perhaps by virtue of game playing being less sedentary or related to a different lifestyle than viewing television and using computer.

Developmental anomalies of the dentition are not infrequently observed by the dental practitioner. The aim of the present study was to determine the prevalence of dental anomalies in the Indian population. A retrospective study of 4133 panoramic radiographs of patients, who attended the Department of Oral Medicine and Radiology, Jodhpur Dental College General Hospital between September 2008 to December 2012 was done. The ages of the patients ranged from 13 to 38 years with a mean age of 21.8 years. The orthopantomographs (OPGs) and dental records were examined for any unusual finding such as congenitally missing teeth, impactions, ectopic eruption, supernumerary teeth, odontoma, dilacerations, taurodontism, dens in dente, germination and fusion, among others. 1519 (36.7%) patients had at least one dental anomaly. The congenitally missing teeth 673 (16.3%) had the highest prevalence, followed by impacted teeth 641 (15.5%), supernumerary teeth 51 (1.2%) and microdontia 41 (1.0%). Other anomalies were found at lower prevalence ranging from transposition 7 (0.1%) to ectopic eruption 30 (0.7%). The most prevalent anomaly in the Indian population was congenitally missing teeth (16.3%), and the second frequent anomaly was impacted teeth (15.5%), whereas, macrodontia, odontoma and transposition were the least frequent anomalies, with a prevalence of 0.2%, 0.2% and 0.1% respectively. While the overall prevalence of these anomalies may be low, the early diagnosis is imperative for the patient management and treatment planning. Key words:Dental anomaly, prevalence, panoramic radiography.

Chronic widespread pain prevalence in the general population: A systematic review.

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. This analyses

Little is known about the prevalence of nonalcoholic fatty liver disease (NAFLD) among severely obese adolescents or factors that determine its development. We investigated the prevalence of NAFLD in a multicenter cohort of adolescents undergoing bariatric surgery and the factors associated with it. We enrolled 242 adolescents undergoing bariatric surgery between March 2007 and February 2012 at 5 tertiary care centers into a multicenter, prospective observational cohort study. Intraoperative core liver biopsies were collected from 165 subjects; 17 were excluded because of insufficient liver tissue or use of hepatotoxic medications, so 148 remained in the study (mean age, 16.8 ± 1.6 years; median body mass index = 52 kg/m(2)). Liver tissues were analyzed by histology using validated criteria. Hepatic gene expression was analyzed in 67 samples. NAFLD was present in 59% of this predominantly female (72%), white (68%), non-Hispanic (91%) cohort. Of subjects with NAFLD, 24% had borderline and 10% had definite nonalcoholic steatohepatitis (NASH). Mild fibrosis (stage 2 or lower) was observed in 18% of liver biopsies and stage 3 was observed in 0.7%, but cirrhosis was not detected. Dyslipidemia was present in 78% of subjects, hypertension in 44%, and diabetes in 14%. More severe NAFLD was associated with increasing levels of alanine aminotransferase, fasting glucose level, hypertension (each P adolescents undergoing bariatric surgery in this cohort had NAFLD, yet the prevalence of severe or fibrotic NASH was low. Increasing severity of NAFLD was associated with level of alanine aminotransferase and cardiometabolic risk factors, but not body mass index. Based on gene expression analysis, borderline and definite NASH were associated with abnormal immune function, intestinal cholesterol absorption, and lipid metabolism. Copyright © 2015 AGA Institute.

Although the epidemiology of Eating Disorders (ED) has been highly developed in Spain, further research considering false negatives and also the prevalence of these disorders in males are needed. They were the aims of the present study. One thousand and seventy six adolescents (500 males and 576 females) participated in a two-stage survey. At the age of 13, apart from exploring numerous clinical and psychosocial variables, they were assessed by means of self-administered screening instruments, the eating attitude test (EAT), bulimic investigatory test Edinburgh (BITE), and body shape questionnaire (BSQ). The subjects were interviewed again 2 years later. Afterwards, 159 probable cases and 150 controls were interviewed by means of the structured interview SCAN. Prevalence of ED in adolescents was 3.71% (95% CI 2.58-4.83; 6.4% of females, 0.6% of males): anorexia nervosa 0.1%, bulimia nervosa 0.75%, eating disorder not otherwise specified (EDNOS) = 2.88%. The rate of false negative was 2.6% of the control group and most of them were EDNOS. The prevalence of ED obtained in our study, higher than others found in previous Spanish research, and a relatively high percentage of false negatives both indicate that up to now the prevalence of ED in Spanish adolescents could be underestimated.

Background After the worldwide steep increase in child and adolescent overweight and obesity during the last decades, there is now evidence of a levelling off in the prevalence in many countries in the Western world. Aim To examine whether there still is a plateau in the prevalence of overweight and obesity in Danish children and adolescents, or whether the prevalence is decreasing or rising again. Methods The trends in the prevalence rates were based on three data sets providing comparable repeated estimates: 1) the Danish Health Visitors Child Health Database (DHVCHD) with measurements on infant and childhood height and weight from 2002 to 2011 (n up to 39,984), 2) the Danish National Birth Cohort (DNBC) with maternal reports of measured infant and childhood height and weight from 1998 to 2010 (n up to 56,826) and 3) the Danish part of the Health Behaviour in School-aged Children survey (HBSC) with self-reported information on adolescent height and weight from the years 2002 to 2010 (n = 16,557). Overweight and obesity were categorized according to WHO growth standards. Trends were assessed by repeated point estimates and linear regression analyses providing regression coefficients for changes in per cent per year with 95% confidence intervals (CI). Results The prevalence rates of overweight and obesity for infants, children and adolescents showed a mixed pattern of decline, stability and increase (ranging from -1.10 through 0.29 per cent per year with CI’s from -3.10 through 2.37). Overall, there were no consistent statistically significant trends upwards or downwards, although some significant downward trends in childhood and adolescence were observed. Conclusion This study, based on data from 1998 through 2011, showed that the prevalence rates of overweight and obesity among Danish infants, children and adolescents were largely still on a plateau with tendencies for a decline among children and adolescents.

Full Text Available Espen Enerly, Cecilia Olofsson, Mari NygårdDepartment of Research, Cancer Registry of Norway, Oslo, NorwayAbstract: Human papillomavirus (HPV is the main cause of cervical cancer, and many countries now offer vaccination against HPV to girls by way of government-funded national immunization programs. Monitoring HPV prevalence in adolescents could offer a near-term biological measure of vaccine impact, and urine sampling may be an attractive large-scale method that could be used for this purpose. Our objective was to provide an overview of the literature on HPV DNA detection in urine samples, with an emphasis on adolescents. We searched the PubMed database using the terms “HPV” and “urine” and identified 21 female and 14 male study populations in which HPV prevalence in urine samples was reported, four of which included only asymptomatic female adolescents. We provide herein an overview of the recruitment setting, age, urine sampling procedure, lesion type, HPV assay, and HPV prevalence in urine samples and other urogenital samples for the studies included in this review. In female study populations, concordance for any HPV type and type-specific concordance in paired urine and cervical samples are provided in addition to sensitivity and specificity. We concluded that few studies on HPV prevalence in urine samples have been performed in asymptomatic female adolescent populations but that urine samples may be a useful alternative to cervical samples to monitor changes in HPV prevalence in females in the post-HPV vaccination era. However, care should be taken when extrapolating HPV findings from urine samples to the cervix. In males, urine samples do not seem to be optimal for monitoring HPV prevalence due to a low human genomic DNA content and HPV DNA detection rate compared to other urogenital sites. In each situation the costs and benefits of HPV DNA detection in urine compared to alternative monitoring options should be carefully

ABSTRACT The nutrition transition with associated lifestyle-related non-communicable diseases has rapidly reached many developing countries, including Saudi Arabia. Therefore, the objective of this study was to examine the prevalence of overweight, obesity, and abdominal obesity among Saudi adolescents. This school-based multicentre cross-sectional study was conducted during 2009-2010 in three major cities in Saudi Arabia: Al-Khobar, Jeddah, and Riyadh. Participants included 2,908 students of secondary schools (1,401 males and 1,507 females) aged 14 to 19 years, randomly selected using a multistage stratified cluster-sampling technique. Weight, height, and waist-circumference were measured; prevalence of overweight and obesity was determined using age- and sex-specific BMI cutoff reference standards of the International Obesity Task Force (IOTF). Abdominal obesity was determined using waist-to-height ratio (WHtR) cutoffs (above 0.5). The prevalence of overweight was 19.5% in males and 20.8% in females while that of obesity was 24.1% in males and 14% in females. The prevalence of abdominal obesity in males and females was 35.9% and 30.3% respectively. Higher prevalence of obesity was observed among adolescents in private schools. Across all ages, overweight and obesity ranged from 39.9% to 45.6% in males and from 30.4% to 38.7% in females. ANCOVA, controlling for age, showed significant interaction effects (city by gender). It is concluded that the proportions of overweight, obesity, and abdominal obesity, observed among Saudi adolescents were remarkably high. Such high prevalence of overweight and obesity is a major public-health concern. PMID:25895197

The increasing prevalence of overweight and obesity among children is now an important health problem. This fact, however, does not reflect the scale of the problem. The aim of the present study was to find how much the BMI threshold was exceeded in a population from Kraków. The study was based on three cross-sectional surveys conducted in 1983, 2000 and 2010. The prevalence of overweight and obesity was estimated based on the International Obesity Task Force cut-off points. In addition to these, an extent of overweight (EOW) index was calculated. Poland. Children aged 3-18 years (n 14 534) from Kraków. Between the populations examined in 1983 and 2010, the EOW index in boys rose by almost 10 %, and the prevalence of overweight and obesity by 39 %. In girls, however, the EOW index decreased by 45 %, while the prevalence of overweight and obesity remained at similar levels. Analyses in separate age groups showed that the EOW index increased only among early adolescents (150 % for boys, 94 % for girls) and late adolescents (390 % and 64 %, respectively). The observed increased prevalence of overweight and obesity mainly concerned boys and was accompanied by an increase in the amount by which the BMI threshold values were exceeded.

Full Text Available Abstract Background The condition of obesity has become a significant public health problem in the United States. In children and adolescents, the prevalence of overweight has tripled in the last 20 years, with approximately 16.0% of children ages 6–19, and 10.3% of 2–5 year olds being considered overweight. Considerable research is underway to understand obesity in the general pediatric population, however little research is available on the prevalence of obesity in children with developmental disorders. The purpose of our study was to determine the prevalence of overweight among a clinical population of children diagnosed with attention deficit hyperactivity disorder (ADHD and autism spectrum disorders (ASD. Methods Retrospective chart review of 140 charts of children ages 3–18 years seen between 1992 and 2003 at a tertiary care clinic that specializes in the evaluation and treatment of children with developmental, behavioral, and cognitive disorders. Diagnostic, medical, and demographic information was extracted from the charts. Primary diagnoses of either ADHD or ASD were recorded, as was information on race/ethnicity, age, gender, height, and weight. Information was also collected on medications that the child was taking. Body mass index (BMI was calculated from measures of height and weight recorded in the child's chart. The Center for Disease Control's BMI growth reference was used to determine an age- and gender-specific BMI z-score for the children. Results The prevalence of at-risk-for-overweight (BMI >85th%ile and overweight (BMI > 95th%ile was 29% and 17.3% respectively in children with ADHD. Although the prevalence appeared highest in the 2–5 year old group (42.9%ile, differences among age groups were not statistically significant. Prevalence did not differ between boys and girls or across age groups (all p > 0.05. For children with ASD, the overall prevalence of at-risk-for-overweight was 35.7% and prevalence of overweight

Many researchers and professionals have reported nonsubstance addiction to online entertainments in adolescents. However, very few scales have been designed to assess problem Internet use in this population, in spite of their high exposure and obvious vulnerability. The aim of this study was to review the currently available scales for assessing problematic Internet use and to validate a new scale of this kind for use, specifically in this age group, the Problematic Internet Entertainment Use Scale for Adolescents. The research was carried out in Spain in a gender-balanced sample of 1131 high school students aged between 12 and 18 years. Psychometric analyses showed the scale to be unidimensional, with excellent internal consistency (Cronbach's alpha of 0.92), good construct validity, and positive associations with alternative measures of maladaptive Internet use. This self-administered scale can rapidly measure the presence of symptoms of behavioral addiction to online videogames and social networking sites, as well as their degree of severity. The results estimate the prevalence of this problematic behavior in Spanish adolescents to be around 5 percent.

Diabetes is an important contributor to global morbidity and mortality. The contributions of population aging and macroeconomic changes to the growth in diabetes prevalence over the past 20 years are unclear. We used cross-sectional data on age- and sex-specific counts of people with diabetes by country, national population estimates, and country-specific macroeconomic variables for the years 1990, 2000, and 2008. Decomposition analysis was performed to quantify the contribution of population aging to the change in global diabetes prevalence between 1990 and 2008. Next, age-standardization was used to estimate the contribution of age composition to differences in diabetes prevalence between high-income (HIC) and low-to-middle-income countries (LMICs). Finally, we used non-parametric correlation and multivariate first-difference regression estimates to examine the relationship between macroeconomic changes and the change in diabetes prevalence between 1990 and 2008. Globally, diabetes prevalence grew by two percentage points between 1990 (7.4 %) and 2008 (9.4 %). Population aging was responsible for 19 % of the growth, with 81 % attributable to increases in the age-specific prevalences. In both LMICs and HICs, about half the growth in age-specific prevalences was from increasing levels of diabetes between ages 45-65 (51 % in HICs and 46 % in LMICs). After age-standardization, the difference in the prevalence of diabetes between LMICs and HICs was larger (1.9 % point difference in 1990; 1.5 % point difference in 2008). We found no evidence that macroeconomic changes were associated with the growth in diabetes prevalence. Population aging explains a minority of the recent growth in global diabetes prevalence. The increase in global diabetes between 1990 and 2008 was primarily due to an increase in the prevalence of diabetes at ages 45-65. We do not find evidence that basic indicators of economic growth, development, globalization, or urbanization were related

Child and Adolescent Twin Study and national patient register, Sweden. 19, 993 twins (190 with autism spectrum disorder) and all children (n=1,078,975; 4620 with autism spectrum disorder) born in Sweden over a 10 year period from 1993 to 2002. Annual prevalence of the autism symptom phenotype (that is, symptoms on which the diagnostic criteria are based) assessed by a validated parental telephone interview (the Autism-Tics, ADHD and other Comorbidities inventory), and annual prevalence of reported diagnoses of autism spectrum disorder in the national patient register. The annual prevalence of the autism symptom phenotype was stable during the 10 year period (P=0.87 for linear time trend). In contrast, there was a monotonic significant increase in prevalence of registered diagnoses of autism spectrum disorder in the national patient register (Pautism symptom phenotype has remained stable in children in Sweden while the official prevalence for registered, clinically diagnosed, autism spectrum disorder has increased substantially. This suggests that administrative changes, affecting the registered prevalence, rather than secular factors affecting the pathogenesis, are important for the increase in reported prevalence of autism spectrum disorder. © Lundström et al 2015.

Stress-related eating is associated with unhealthy eating and drinking habits and an increased risk of obesity among adults, but less is known about factors related to stress-driven eating behaviour among children and adolescents. We studied the prevalence of stress-related eating and its association with overweight, obesity, abdominal obesity, dietary and other health behaviours at the age of 16. Furthermore, we examined whether stress-related eating is predicted by early-life factors including birth size and maternal gestational health. The study population comprised 3598 girls and 3347 boys from the Northern Finland Birth Cohort 1986 (NFBC1986). Followed up since their antenatal period, adolescents underwent a clinical examination, and their stress-related eating behaviour, dietary habits and other health behaviours were assessed using a postal questionnaire. We examined associations using cross-tabulations followed by latent class analysis and logistic regression to profile the adolescents and explain the risk of obesity with behavioural traits. Stress-related eating behaviour was more common among girls (43%) than among boys (15%). Compared with non-stress-driven eaters, stress-driven eaters had a higher prevalence of overweight, obesity and abdominal obesity. We found no significant associations between stress-eating and early-life factors. Among girls, tobacco use, shorter sleep, infrequent family meals and frequent consumption of chocolate, sweets, light sodas and alcohol were more prevalent among stress-driven eaters. Among boys, the proportions of those with frequent consumption of sausages, chocolate, sweets, hamburgers and pizza were greater among stress-driven eaters. For both genders, the proportions of those bingeing and using heavy exercise and strict diet for weight control were higher among stress-eaters. Besides a 'healthy lifestyle' cluster, latent class analysis revealed two other patterns ('adverse habits', 'unbalanced weight control') that

Depression in adolescents is a matter of concern because of its high prevalence, potential recurrence and impairment of functioning in the affected individual. The study sought to determine the prevalence of depressive symptoms among adolescents in Nairobi (Kenya) public secondary schools; make a comparison between day and boarding students; and identify associated factors in this population. A random sample of school going adolescents was taken from a stratified sample of 17 secondary schools out of the 49 public secondary schools in Nairobi province. The sample was stratified to take into account geographical distribution, day and boarding schools, boys only, girls only and mixed (co-education) schools in the capital city of Kenya. Self administered instruments (EMBU and CDI) were used to measure perceived parental behaviour and levels of depression in a total of 1,276 students excluding those who had no living parent. The prevalence of clinically significant depressive symptoms was 26.4%. The occurrence was higher in girls than it was in boys p<0.001. Students in boarding schools had more clinically significant depressive symptoms compared to day students (p=0.01). More girls exhibited suicidal behaviour than boys (p<0.001). There was a significant correlation between depressive symptoms and suicidal behaviour (p<0.001). CDI scores correlated positively with age (p<0.001) with an increase in CDI score with unit increase in age among students 14-17 years old, perceived rejecting maternal parenting behaviour (p<0.001), perceived no emotional attachment paternal behaviour (p<0.001), perceived no emotional attachment maternal behaviour (p<0.001), and perceived under protective paternal behaviour (p=0.005). Perceived maladaptive parental behaviours are substantially associated with the development of depressive symptoms and suicidal behaviour in children.

The Prevalence of High-Risk HPV Types and Factors Determining Infection in Female Colombian Adolescents.

Directory of Open Access Journals (Sweden)

Luisa Del Río-Ospina

Full Text Available This study reports six HR-HPV types' infection prevalence discriminated by species and multiple infection in unvaccinated Colombian female adolescents, as well as some factors modulating the risk of infection. HPV DNA for six high-risk viral types was identified in cervical samples taken from 2,134 12-19 year-old females using conventional generic and type-specific PCR. Binomial logistical regression analysis was used for modelling HR-HPV infection and multiple infection risk. The interaction between variables in a stepwise model was also included in such analysis. Viral DNA was detected in 48.97% of the females; 28.52% of them had multiple infections, HPV-16 being the most frequently occurring type (37.44%. Cytological abnormality prevalence was 15.61%. Being over 16 years-old (1.66: 1.01-2.71 95%CI, white ethnicity (4.40: 1.16-16.73 95%CI, having had 3 or more sexual partners (1.77: 1.11-2.81 95%CI and prior sexually-transmitted infections (STI (1.65: 1.17-2.32 95%CI were associated with a greater risk of HPV infection. Having given birth was related to a higher risk of infection by A7 species and antecedent of abortion to less risk of coinfection. Where the females in this study came from also influenced the risk of infection by A7 species as female adolescents from the Andean region had a lower risk of infection (0.42: 0.18-0.99 95%CI. The presence of factors related to risky sexual behaviour in the study population indicated that public health services should pay special attention to female adolescents to modify the risk of infection by high-risk HPV types and decrease their impact on this age group.

2013-01-01

Background: The recommended anthropometric methods to assess the weight status include body mass index (BMI), skinfold thickness, and waist circumference. However, these methods have advantages and disadvantages regarding the classification of overweight and obesity in adolescents. Aims: The study was to analyze the correlation between the measurements of BMI, skinfold thickness and waist circumference to assess overweight and obesity in Portuguese adolescents. Materials and Methods: A sample of 966 students of Portugal was used. Of them, 437 (45.2%) were males and 529 (54.8%) were females aged between 10 and 16 years. The evaluations included BMI calculation, skinfold thickness, and waist circumference measurements. Results: This study revealed a high prevalence of overweight and obesity with values ranging from 31.6%, 61.4%, and 41.1% according to the measurement of BMI, skinfold thickness, and waist circumference, respectively. The results found a high level of correlation between BMI and skinfold thickness (P < 0.001, r = 0.712), between BMI and waist circumference (P < 0.001, r = 0.884), and waist circumference and skinfold thickness (P < 0.001, r = 0.701). Conclusions: This study revealed a high prevalence of overweight and obesity in Portuguese adolescents using three different anthropometric methods, where the BMI showed the lowest values of prevalence of overweight and obesity and the skinfold thickness showed the highest values. The three anthropometric methods were highly correlated. PMID:24404544

Studies from a number of countries have indicated an increased risk of obesity in adolescents with intellectual disability. Whether risk factors for adults with intellectual disability apply to adolescents however is uncertain. This study examines obesity in a community sample of adolescents with intellectual disability in Australia, and investigates risk factors associated with obesity and overweight. A cross-sectional survey and medical record review on 261 adolescents with intellectual disability attending special education facilities in South-East Queensland, Australia between January 2006 and September 2010 was conducted. Information on age, gender, weight, height, syndrome specific diagnoses, problematic behaviours, mobility, taking psychotropic or epileptic medication, and perceived household financial difficulties was collected. Body mass index (BMI) was calculated and participants categorised as normal/underweight, overweight or obese according to the International Obesity Taskforce definitions. Overall 22.5% (95% CI: 17.8-28.0%) of adolescents were obese, and 23.8% (95% CI: 19.0-29.4%) were overweight, a marked increase compared to Australian norms. Adolescents with Down syndrome were more likely to be obese than other participants (odds ratio=3.21; 95% CI: 1.41-7.30). No association was found with other risk factors examined. Prevalence of obesity and overweight were increased compared to general Australian adolescents. The only significant risk factor was the presence of Down syndrome. These findings reinforce the need for a health policy and practice response to obesity that is inclusive of individuals with intellectual disability.

Methods: Secondary analysis of a study on the Behavior of Adolescents from Santa Catarina (CompAC 2. Cross-sectional school-based study of 6,529 high-school students (males, n=2,903 from the state of Santa Catarina public education system in 2011, aged 15 to 19 years. Multinomial logistic regression (crude and adjusted was used to measure the association. Results: The highest and lowest prevalence rates were found in the maintenance (43.9% and precontemplation stages (7.0%, respectively. The stages of action, preparation and contemplation showed similar results: 16.2%; 17.0% and 15.6%; respectively. Male adolescents show higher prevalence in the maintenance stage in relation to females and these show a higher prevalence in preparation, contemplation and precontemplation. All the assessed variables (gender, age, area of residence, employment status, family income, maternal education and school grade, with the exception of school shift, were associated with at least one of the stages. Conclusions: A large proportion of adolescents are in the pre-adoption stages and most of these have the intention to start regular physical activity. With the exception of school shift, the assessed variables were associated with stages in different ways, showing different profiles in relation to sociodemographic and economic characteristics in each subgroup.

To examine differences in lifetime prevalence of mental disorder and service use among U.S. adolescents by both immigrant generation and race/ethnicity. A total of 6,250 adolescents aged 13 to 18 years in the National Comorbidity Survey Replication Adolescent Supplement were assessed for lifetime prevalence of mood and/or anxiety disorders, behavior disorders, and mental health service use. Twelve groups defined by self-identified race/ethnicity (non-Hispanic white, Hispanic, non-Hispanic black, Asian) and immigrant generation (first, second, third, or more) were compared. Differences in prevalence of lifetime mental disorder were most apparent when immigrant generation and race/ethnicity were considered jointly. Compared to third+generation non-Hispanic white adolescents, the odds of mood/anxiety disorder were increased among second-generation Asian (adjusted odds ratio [AOR] = 2.51; 95% CI = 1.22-5.17) and third+generation Hispanic (AOR = 1.28; 95% CI = 1.00-1.63) but reduced among first-generation Asian (AOR = 0.27; 95% CI = 0.10-0.71) and second-generation non-Hispanic white adolescents (AOR = 0.50; 95% CI = 0.30-0.81). The odds of behavior disorder were lower among first-generation Asian (AOR = 0.26; 95% CI = 0.09-0.71) and all generations of non-Hispanic black adolescents (AOR range 0.43-0.55). Adjusting for lifetime disorder, first-generation Hispanic and non-Hispanic white adolescents and all generations of non-Hispanic black adolescents were less likely to receive mental health services (AOR range 0.24-0.55). Variation in risk of disorder by immigrant generation and race/ethnicity underscores the importance of considering social, economic, and cultural influences in etiologic and treatment studies of adolescent psychopathology. Lower rates of service use, particularly among first-generation immigrant adolescents, highlight the need to identify and address barriers to recognition and treatment of mental disorders among adolescents from immigrant

Full Text Available Background: Periodontitis is a group of inflammatory diseases affecting the supporting tissues of the tooth. Both aggressive periodontitis (AP and chronic periodontitis (CP have a multifactorial etiology, with dental plaque as the initiating factor. However, the initiation and progression of periodontitis are influenced by other factors including microbiologic, social and behavioral and systemic and genetic factors. The prevalence of periodontal diseases varies in different regions of the world according to the definition of periodontitis and the study population, and there are indications that they may be more prevalent in developing than in developed countries. Materials and Methods: A cross-sectional study was conducted among the adolescents of 15-18 years of age in Mangalore City. One thousand one hundred students aged 15-18 years were selected for the study from the schools and colleges in Mangalore City using a convenient sampling method. The prevalence of AP and CP were assessed in the study using a community periodontal index. Students who were diagnosed clinically and radiographically were subjected to microbiological examination to confirm AP. Results: A high prevalence of gingivitis and periodontitis was found in students belonging to the lower socioeconomic status group compared with the higher socioeconomic groups, which were associated with poor oral hygiene habits. The prevalence of AP was found to be 0.36% and that of CP was found to be 1.5%. Conclusion: Oral diseases have a significant impact on the social and psychological aspects of an individual′s life. Exposure to risk factors, such as age, low socio-economic status, poor education, low dental care utilization, poor oral hygiene levels, smoking, psychosocial stress and genetic factors are significantly associated with an increased risk of periodontitis among adolescents. Although genetic factors play a major role in periodontitis, the treatment outcome will still be

Full Text Available Abstract Background Harmful social conditions in early life might predispose individuals to dental status which in turn may impact on adolescents' quality of life. Aims To estimate the prevalence of oral health impacts among 12 yr-old Brazilian adolescents (n = 359 and its association with life course socioeconomic variables, dental status and dental services utilization in a population-based birth cohort in Southern Brazil. Methods Exploratory variables were collected at birth, at 6 and 12 yr of age. The Oral Impacts on Daily Performances index (OIDP was collected in adolescence and it was analyzed as a ranked outcome (OIDP from 0 to 9. Unadjusted and adjusted multivariable Poisson regression with robust variance was performed guided by a theoretical determination model. Results The response rate was of 94.4% (n = 339. The prevalence of OIDP = 1 was 30.1% (CI95%25.2;35.0 and OIDP ≥ 2 was 28.0% (CI95%23.2;32.8. The most common daily activity affected was eating (44.8%, follow by cleaning the mouth and smiling (15.6%, and 15.0%, respectively. In the final model mother schooling and mother employment status in early cohort participant's life were associated with OIDP in adolescence. As higher untreated dental caries at age 6 and 12 years, and the presence of dental pain, gingival bleeding and incisal crowing in adolescence as higher the OIDP score. On the other hand, dental fluorosis was associated with low OIDP score. Conclusion Our findings highlight the importance of adolescent's early life social environmental as mother schooling and mother employment status and the early and later dental status on the adolescent's quality of life regardless family income and use of dental services.

Pediatric both-bone diaphyseal forearm fractures are commonly treated in a variety of clinical settings. Most often, closed reduction followed by immobilization leads to satisfactory results. However, in the adolescent population (10-16 years of age), forearm fractures are more challenging due to less remodeling potential. The purpose of this review was to provide an overview of the anatomy, biomechanics, and treatment options relevant to adolescent patients. A systematic review of peer-reviewed publications and abstracts related to the treatment for pediatric both-bone diaphyseal forearm fractures in adolescents was carried out. Forearm fractures in the pediatric population are most common following indirect blows to the forearm. When treating these fractures using closed reduction, it is important to recognize the muscular attachments of the forearm. In roughly 70-90% of cases, closed reduction leads to adequate alignment. In all cases, return to function is the primary goal; however, exact alignment parameters remain controversial. In the adolescent population, surgical treatment has risen substantially in the last few decades. Intramedullary nailing and open reduction using plate fixation are the two most common operative techniques. Unfortunately, recent results have shown that nonunion, malunion, and overall complication rates are higher in older pediatric patients. Moreover, no consensus exists regarding one technique over another. Both-bone diaphyseal fractures in the adolescent population present unique challenges regarding optimal treatment, especially when considering surgical intervention. Further research is necessary to better understand indications for specific surgical treatment.

According to World Health Organization, for every committed suicide there were 20 suicide attempts at least. In the last decade, despite the increasing awareness on suicide attempts among adolescents in China, there has been no comprehensive system reporting vital statistics. Consequently, the prevalence of suicide attempts reported in some studies ranged variedly. Therefore, the purpose of this study was to provide the first meta-analysis of cross-sectional studies of suicide attempts to fill this gap. Two reviewers independently screened potentially relevant cross-sectional studies of suicide attempts through PubMed-Medline, Embase, Wanfang Data, Chongqing VIP and Chinese National Knowledge Infrastructure databases using the core terms 'suicid*'/'suicide attempt*'/'attempted suicide' and 'adolescen*'/'youth'/'child*'/'student*' and 'China'/'Chinese' in the article titles, abstracts and keywords. Chi-square based Q test and I(2) statistic assessed the heterogeneity. Forest plot was used to display results graphically. Potential publication bias was assessed by the funnel plot, Begg's and Egger's test. In total, 43 studies with 200,124 participants met the eligibility criteria. The pooled prevalence of suicide attempts among Chinese adolescents was 2.94% (95% CI: 2.53%-3.41%). Substantial heterogeneity in prevalence estimates was revealed. Subgroup analyses showed that the prevalence for males was 2.50% (95% CI: 2.08%-3.01%), and for females was 3.17% (95% CI: 2.56%-3.91%). In sum, abstracting across the literatures, the prevalence of suicide attempts among Chinese adolescents was moderate compared with other countries around the world. Necessary measures should be set out prevent them in the future. Copyright © 2015 Elsevier Inc. All rights reserved.

Full Text Available Introduction: The pattern of skin diseases in any community is influenced by genetic constitution, climate, socioeconomic status, occupation, education, hygienic standards, customs and quality of medical care. The burden of skin disease also has an impact on the Quality of Life of adolescents. This study aims to investigate the level of awareness and assess the prevalence of different types of skin diseases among adolescents in Mauritius. Material and Methods: 500 adolescents and young adults of both sexes and aged between 11-23 years were recruited. A questionnaire was used to elicit information and to assess the knowledge status of skin diseases and to determine possible risk factors. In addition, a validated questionnaire based on Quality of Life Index was used to determine the psychosocial effect of adolescents suffering from skin diseases. Data was analysed using IBM Statistics SPSS version 20 and Microsoft Excel 2007. Results: Incidence of skin diseases was 22.9% in males and 24.7% females respectively. Acne was the most common skin problems in both gender followed by fungal infection (2.9% in males and eczema (2.4% in females. Climatic conditions (e.g summer, consumption of oily and spicy foods, sports practice and familial history were correlated positively with prevalence of skin diseases. Conclusion: Acne, eczema and fungal infection were the most common skin diseases identified. The findings also indicate that more respondents between 15-19 years old were more prone to skin diseases.

Prior research has not yet investigated the prevalence of body dysmorphic disorder (BDD) in adolescents and young adults based on criteria from the Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5). In the current study, the point prevalence of BDD, comorbid symptoms, and associated features, such as appearance-related suicidality, level of insight or history of plastic surgeries, were examined in a non-clinical sample of German adolescents and young adults (n=308), between 15 and 21 years old, using self-report measures. Eleven participants (3.6%; 95% CI=[1.9, 5.8]) met DSM-5 criteria for BDD. Self-reported BDD (vs. no-BDD) was related to respondents showing significantly more obsessive-compulsive (OC) symptoms and lower degrees of insight regarding appearance concerns. Significantly more adolescents and young adults with vs. without self-reported BDD (36.4% vs. 8.8%) reported appearance-related suicidal ideation. In conclusion, body dysmorphic symptoms are common in adolescents and young adults and are associated with high rates of comorbid symptoms and suicidal ideation.

Obesity prevalence has increased among children and adolescents during recent decades, leading to a rise in Type 2 diabetes mellitus (DM II prevalence in these two age brackets. Hence, the aim of this study was to assess impaired glucose tolerance and insulin resistance, and gather metabolic findings in obese children and adolescents.Methods and materials: We studied 110 obese children and adolescents (body mass index > 95th percentile for age and gender 4–18 years of age referred to the endocrine clinic of the Children’s Hospital at Tabriz University in a descriptive cross-sectional study. ­Fasting glucose, insulin, and lipid profile in all subjects were determined. Oral glucose tolerance test after eating 75 g/kg glucose was performed. Homeostatic model assessment was used to ­estimate insulin resistance.Results: Impaired glucose tolerance and insulin resistance prevalence in 68 obese adolescents was 14.7% and 31.8%, respectively. Impaired glucose tolerance and insulin resistance was not seen in 23.8% of 42 obese children. No case of DM II was seen. There was a significant statistical difference in glucose (P = 0.003 and insulin (P < 0.001 level at minute 120 in individuals with impaired glucose tolerance compared to obese children and adolescents without impaired glucose tolerance. Rate of insulin resistance in patients with impaired glucose tolerance was greater and had a significant statistical difference (P = 0.03.Conclusion: Obesity has a close relationship with increased risk of impaired glucose tolerance and insulin resistance in children and adolescents.

Full Text Available The prevalence and age distribution of Epstein-Barr virus infection varies in different populations and there is little information about the epidemiology of this infection in Brazil. We studied the prevalence of EBV antibodies in a sample of 283 children and adolescents between 1 and 21 years old. The sample was taken from two neighborhoods in Vitória (capital city of Espirito Santo, Brazil. The São Pedro (SP neighborhood represented an area with lower socioeconomic status and the Praias (P neighborhood represented an area with higher SES. Anti-VCA (Virus Capsid Antigen antibodies were detected by ELISA and anti-EBNA (Epstein-Barr Nuclear Antigen antibodies were detected by an anti-complement immunofluorescence method, both using commercial kits. The results showed an overall prevalence rates of anti-VCA and anti-EBNA of 71% and 54% respectively. The prevalence for both anti-EBV antibodies was higher and probably the infection occurred earlier in the SP neighborhood. Among the various socioeconomic factors studied only low family income and maternal education level were significantly correlated with a higher frequency of positive serology for anti-VCA. These results demonstrate that there is a high prevalence of EBV antibodies in children and adolescents living in Vitória, that occurs more frequently at a younger age in children from families with low socioeconomic status. In addition, the results demonstrate an intermediate age distribution pattern between those reported in developed and underdeveloped countries.

Full Text Available An observational study of the Kaiser Permanente Northern California (KPNC BMI coding distributions was conducted to ascertain the trends in overweight and obesity prevalence among KPNC members aged 2–19 between the periods of 2003–2005 and 2009-2010. A decrease in the prevalence of overweight (−11.1% change and obesity (−3.6% change and an increase in the prevalence of healthy weight (+2.7% change were demonstrated. Children aged 2–5 had the greatest improvement in obesity prevalence (−11.5% change. Adolescents aged 12–19 were the only age group to not show a decrease in obesity prevalence. Of the racial and ethnic groups, Hispanics/Latinos had the highest prevalence of obesity across all age groups. The KPNC prevalence of overweight and obesity compares favorably to external benchmarks, although differences in methodologies limit our ability to draw conclusions. Physician counseling as well as weight management programs and sociodemographic factors may have contributed to the overall improvements in BMI in the KPNC population. Physician training, practice tools, automated BMI reminders and performance feedback improved the frequency and quality of physician counseling. BMI screening and counseling at urgent visits, in addition to well-child care visits, increased the reach and dose of physician counseling.

Full Text Available Background: With a rising trend of Non-Communicable Diseases (NCDs in the present world, overweight and obesity has gained importance as it is not only a disease in itself but also risk factor for majority of other NCDs. A dramatic increase in overweight and obesity among children and adolescent has raised the concern of various public health physicians especially in developing country like India. Aims & Objective: To study the prevalence of overweight and obesity & its correlates among school going adolescents of Haldwani block. Material & Methods: School based cross sectional study was done among the adolescents of 8th to 12th standard. To calculate the maximum sample size prevalence of obesity was assumed to be 50%, taking absolute error of 5%, design effect of 2 and 10% non-response rate the sample was calculated to be 880, rounded off to 900. Samples were collected from 30 clusters/schools using simple random sampling. Data was collected using a pre-designed, semi-structured and pre-tested questionnaire and analyzed by using SPSS version 22. Results: Prevalence of overweight and obesity was 13% (CI = 10.8 - 15.2%. Overweight and obesity was found to be significantly associated with urban area, private school, Socio-economic class I, non-vegetarian diet, physical inactivity and playing videogames, working on laptops and computer on univariate analysis. On applying binary logistic regression factors like private schools, socioeconomic class I, non-vegetarian diet and physical inactivity were again found to be significantly associated with overweight and obesity. Conclusion: Prevalence of obesity was found to be more in adolescents having modifiable risk factors.

Intention to smoke is a valid and reliable factor for predicting future smoking habits among adolescents. This factor, however, has received inadequate attention in Malaysia. The present paper elaborates the prevalence and factors associated with intent to initiate or to cease smoking, among adolescent nonsmokers and smokers in Kota Tinggi, Johor, Malaysia. A total of 2,300 secondary school students aged 13-16 years were selected through a two-stage stratified sampling method. A set of standardized questionnaires was used to assess the smoking behavior among adolescents and the inter-personal and intra-personal factors associated with smoking intention (intention to initiate smoking or to cease smoking). Multivariable logistic regression was used to identify factors related to smoking intention. The prevalence of intention to smoke in the future or to cease smoking among non- smoking adolescents and current smokers were 10.7% and 61.7% respectively. Having friends who smoke, social influence, and poor knowledge about the ill effects on health due to smoking showed significant relationships with intention to smoke in the future among non-smokers. Conversely, perceived lower prevalence of smoking among peers, weak contributory social influence, and greater awareness of the ill effects of smoking are factors associated with the intention to cease smoking sometime in the future. The study found that prevalence of intention to initiate smoking is low among non-smokers while the majority of current smokers intended to cease smoking in the future. Existing anti-smoking programmes that integrate the factors that have been identified in the current study should be put in motion to reduce the prevalence of intention to initiate smoking and increase the intention to cease smoking among adolescents.

Full Text Available OBJECTIVE: To assess the prevalence and the factors associated with common mental disorders among adolescents in Pelotas, a southern Brazilian city. METHOD: A population based cross-sectional study was carried out in the urban area of Pelotas. Multi-stage sampling was used to obtain a sample of adolescents aged between 15 and 18 years. Adolescents were interviewed using a self-report confidential questionnaire. The presence of common mental disorders was assessed using the Self-Reporting Questionnaire 20 (SRQ-20. Multivariate analysis was carried out using the Poisson regression with a robust adjustment of variance and control for design effect. RESULTS: Nine hundred and sixty adolescents were interviewed. The prevalence of common mental disorders was 28.8%. Adolescents aged 17 years showed prevalence of 1.37 (95% CI 1.06-1.78 times greater than the 15 year olds. Adolescents whose mothers had between 5 and 8 years of schooling had a prevalence 1.42 (95% CI 1.01-1.51 times greater than those whose mothers had more than 8 years of schooling. Smoking and sedentary behavior were also associated with an increased prevalence of common mental disorders. Those who were dissatisfied with their body image showed a prevalence of 1.47 (95% CI 1.07-2.02. CONCLUSIONS: Maternal schooling, tobacco smoking, sedentary behavior and body image dissatisfaction were factors associated with the presence of common mental disorders.OBJETIVO: Avaliar a prevalência e os fatores associados à presença de transtornos mentais comuns entre adolescentes em Pelotas, uma cidade do sul do Brasil.

Back pain affects people of all ages. This may be associated with physical inactivity, and in the case of physical activity in different domains, the relationship with back pain is not clear in the literature. The aim of this study was to estimate the prevalence of low back and neck pain and investigate their association in different domains of physical inactivity. 1011 randomly selected students participated in this study. Neck and back pain were assessed using the Nordic questionnaire, whereas the Baecke Physical Activity questionnaire was used to measure physical activity domains. Separate Binary Logistic Regression models were performed to investigate the association of physical activity domains with neck or back pain. 17.4% of the students reported cervical pain, while 18.0% reported low back pain. Older adolescents had a higher prevalence of cervical pain (24.4%) than younger adolescents (11.9%) (p value pain, being 25.1% in older adolescents and 12.4% in younger (p value pain in the cervical region [OR 0.67 (0.44-0.99)] or back pain [OR 0.60 (0.40-0.91)]. Being inactive in occupational activities was associated with cervical pain [OR 1.49 (1.06-2.10)]. Being inactive in the sports environment presented a marginal relationship with pain in the cervical region [OR 1.41 (0.99-2.02)]. The prevalence of neck and low back pain was higher in older adolescents and physical inactivity in the sporting context and occupational activities could be a risk factor to increase the chances of back pain.

To study the prevalence of menstruation-related headache and the impact of associated factors in adolescents. This cross-sectional study was conducted in seven randomly selected high schools, and 3,886 girls attending those schools were invited. After the consent of the school principals, a final total of 2,485 girls (63.9%) were involved in the study. A specific questionnaire was distributed to adolescent girls (14-19 years old). The first part of the survey investigated the features of menstruation (age of first menstruation, duration of period, pad fully soaked per day). The last part of the questionnaire surveyed the presence of headache during the menstruation period. The severity of headache was measured by a visual analogue scale. Lastly, participants were requested to complete the Beck Depression Inventory (BDI). The prevalence of menstruation-related headache and associated factors were studied. The mean age of the study group was 15.89 ± 1.07 (14-19) years old. The age of onset of menarche was younger than 12 years old in 32.4% of girls, and mean age of onset of menarche was 12.96 ± 1.09 years old. The prevalence of menstruation-related headache was calculated to be 25.9% (n = 646). The onset of menstruation before the age of 12 years old, longer duration of menstruation period, dysmenorrhea, daily consumption of coffee and cola and smoking significantly affected the frequency of menstruation-related headache. The mean scores of the BDI were calculated as 21.68 ± 13.65 and a significant relationship was found between headache and BDI scores. Our study indicates that menstruation-related headache is a common problem of adolescent girls. It might be associated with different comorbidities such as depression. Accordingly, a multidisciplinary treatment approach must be considered to improve their life quality. This article is protected by copyright. All rights reserved.

2016-01-01

BACKGROUND: Atopic diseases are among the most common chronic diseases in adolescents, and it is uncertain whether the prevalence of atopic diseases has reached a plateau or is still increasing. The use of the ISAAC (International Study of Asthma and Allergy in Childhood) questionnaire has provided......: The children were examined eight times from birth to 14 years. Visits included questionnaire-based interviews, clinical examination, skin prick test, and specific IgE. RESULTS: Follow-up rate at 14 years was 66.2%. The 12-month prevalence of any atopic disease was high (40.3%) mostly due to a high prevalence...... comparable prevalence rates from many countries, whereas studies including clinical examinations and strict diagnostic criteria are scarce. We aimed to investigate the prevalence of atopic diseases, the pattern of sensitization, and comorbidities at 14 years in a prospective birth cohort. METHODS...

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.

Full Text Available Georgios D Floros 2nd Department of Psychiatry, Medical School, Aristotle University of Thessaloniki, Thessaloniki, Greece Abstract: Research on adolescence gambling over the past twenty years has revealed significant incidence and prevalence rates and highlighted the possible negative effects on an adolescent’s well-being. Several risk and protective factors have also been identified. Over the course of the past few years, technological advances have heralded the advent of new avenues for gambling as well as new opportunities to gamble without any direct monetary exchange. This review article examines those established trends as well as the new issues that we are faced with, in order to accurately portray the current challenges in research, prevention, and treatment.

2007-07-01

Full Text Available Abstract Background To present and compare population-based and antenatal-care (ANC sentinel surveillance HIV prevalence estimates among women in a rural South African population where both provision of ANC services and family planning is prevalent and fertility is declining. With a need, in such settings, to understand how to appropriately adjust ANC sentinel surveillance estimates to represent HIV prevalence in general populations, and with evidence of possible biases inherent to both surveillance systems, we explore differences between the two systems. There is particular emphasis on unrepresentative selection of ANC clinics and unrepresentative testing in the population. Methods HIV sero-prevalence amongst blood samples collected from women consenting to test during the 2005 annual longitudinal population-based serological survey was compared to anonymous unlinked HIV sero-prevalence amongst women attending antenatal care (ANC first visits in six clinics (January to May 2005. Both surveillance systems were conducted as part of the Africa Centre Demographic Information System. Results Population-based HIV prevalence estimates for all women (25.2% and pregnant women (23.7% were significantly lower than that for ANC attendees (37.7%. A large proportion of women attending urban or peri-urban clinics would be predicted to be resident within rural areas. Although overall estimates remained significantly different, presenting and standardising estimates by age and location (clinic for ANC-based estimates and individual-residence for population-based estimates made some group-specific estimates from the two surveillance systems more predictive of one another. Conclusion It is likely that where ANC coverage and contraceptive use is widespread and fertility is low, population-based surveillance under-estimates HIV prevalence due to unrepresentative testing by age, residence and also probably by HIV status, and that ANC sentinel surveillance over

Depression currently affects 350 million people, and its prevalence among adolescents is 4% to 8%. Adolescents who abandon antidepressant treatment or drop out of clinical trials are less likely to recover or experience a remission of symptoms because they are not being followed up by a medical team. The objective of this study was to analyze the dropout rates of randomized clinical trials of depressed adolescents receiving treatment with antidepressant drugs and the factors associated with nonadherence by summarizing this information in a systematic review and meta-analysis. Articles were retrieved from MEDLINE, EMBASE, Cochrane, Clinical Trial, PsycINFO, and Web of Science using the MeSH terms "depressive disorder," "randomized trials," and "adolescents." The evaluation of study quality was performed by using the Cochrane Handbook for Systematic Reviews of Interventions and the Jadad scale. The final sample included 50 articles, of which 44 presented dropout rates. The overall dropout prevalence was 23% (95% CI, 20-27; P dropout prevalence, respectively (33% [95% CI, 27-39], 45% [95% CI, 31-64], and 15% [95% CI, 13-17]). The adverse effects most associated with dropout were attempted suicide followed by mania, skin rash, and headache. Problems relating to clinical trials and family arbitration were also related with dropout. Serotonin/norepinephrine reuptake inhibitor treatment, adolescent age >16 years, and receiving medication were the only factors demonstrating a higher association with dropout rates. Selective serotonin reuptake inhibitors were linked to the lowest prevalence, probably due to fewer perceived problems with related adverse effects and higher efficacy in adolescents. Cognitive-behavioral therapy combined with pharmacotherapy produced a lower nonadherence prevalence; this approach can be an alternative to avoid dropouts and relapse.

Application of the Eating Attitudes Test (EAT-26) in a rural, Zulu speaking, adolescent population in South Africa

Science.gov (United States)

Szabo, Christopher P; Allwood, Clifford W

2004-01-01

This study was undertaken as part of an exploration of the potential risk for future eating disorders in the black female population of South Africa. Previous research has documented eating attitudes suggesting that such a risk exists in urban populations. A translated version of the Eating Attitudes Test (EAT-26) was applied in a Zulu speaking, rural population (n=361). A prevalence of 3% for abnormal eating attitudes was established. In keeping with the hypothesis, the findings suggest that the risk for developing an eating disorder in a rural population is somewhat lower. In this regard, there does appear to be an urban-rural divide, which may have implications for the prevention of the emergence of eating disorders in black, South African adolescents. However, the validity of the EAT-26 in this population is a consideration in interpreting the data. PMID:16633489

2006-02-01

the correspondents in English "fibromyalgia" and "prevalence" had been used. It was selected 97 articles and after reading the summaries, the ones related to the fibromyalgia prevalence with oher diseases were excluded. Only 30 articles evoked the subject prevalence of the fibromyalgia in the population. The selected articles were grouped in five items: a the prevalence of fibromyalgia in adult populations; b prevalence of fibromyalgia in women; c prevalence of fibromyalgia in children and adolescents; d prevalence of fibromyalgia in specific populations; e prevalence of chronic and diffuse pain in the population according to the ACR criteria. RESULTS: Literature points that the prevalence of fibromyalgia in the general population has values between 0,66 and 4,4%, being more prevalent in women than in men, especially in individuals aged between 35 to 60 years. Studies involving children, adolescents or other special groups are few or inconclusive. The prevalence of chronic and diffuse pain in general population althoug rarily been studied points to values between 11 and 13%. CONCLUSION: More studies on prevalence of chronic and diffuse pain must be stimulated, as well as the ones concerning prevalence in the adult population, children and young.

The validity of borderline personality disorder (BPD) in children and adolescents has not been studied in a rigorous manner reflecting the criteria of Robins and Guze first detailed in 1970. This paper and the others in this series address some aspects of this multifaceted validation paradigm, which requires that a disorder has a known clinical presentation, can be delimited from other disorders, 'runs' in families, and something of its aetiology, treatment response and course is known. Three groups of subjects were studied: 104 adolescent inpatients meeting the Revised Diagnostic Interview for Borderlines and DSM-IV criteria for BPD, 60 psychiatrically healthy adolescents and 290 adult inpatients meeting the Revised Diagnostic Interview for Borderlines and DSM-III-R criteria for BPD. Adolescents with BPD had significantly higher prevalence rates of 22 of the 24 symptoms studied than psychiatrically healthy adolescents. Only rates of serious treatment regressions and countertransference problems failed to reach the Bonferroni-corrected level of 0.002. Adolescents and adults with BPD had only four symptomatic differences that reached this level of significance, with adolescents with BPD reporting significantly lower levels of quasi-psychotic thought, dependency/masochism, devaluation/manipulation/sadism and countertransference problems than adults with BPD. Taken together, the results of this study suggest that adolescents report BPD as severe as that reported by adults. They also suggest that BPD in adolescents is not a tumultuous phase of normal adolescence. Copyright © 2017 John Wiley & Sons, Ltd. Copyright © 2017 John Wiley & Sons, Ltd.

This study aimed to determine the trends in prevalence of childhood overweight and malnutrition in a large Chinese ethnic minority population from 1991 to 2010. In the Chinese National Survey on Students' Constitution and Health from 1991 to 2010, multistage stratified sampling was conducted in the series of cross-sectional studies. Participants were 7-18-year-old students randomly selected by sex and region, and included Han and 26 ethnic minorities. During the survey period, the overall prevalence of overweight increased from 5.8% to 13.5%, and malnutrition trend increased from 3.6% to 4.1% in ethnic minority children and adolescents. Moreover, Korean and Mongol children were more likely than Han children to be obese (Korean: RR = 1.52; 95% CI: 1.48-1.56; Mongol: RR = 1.24; 95% CI: 1.20-1.28). Among these minorities, the Dongxiang and Li children were more likely to be malnourished (Li: RR = 1.47; 95% CI: 1.37-1.57; Dongxiang: RR = 1.45; 95% CI: 1.34-1.58). Shui, Khalkhas, Lisu, and Monguor children were less likely to be overweight and malnourished compared with the Hans. The prevalence of overweight among ethnicities increased yearly while that for malnutrition has fluctuated over the past few decades.

Full Text Available Background: With a rising trend of Non-Communicable Diseases (NCDs in the present world, overweight and obesity has gained importance as it is not only a disease in itself but also risk factor for majority of other NCDs. A dramatic increase in overweight and obesity among children and adolescent has raised the concern of various public health physicians especially in developing country like India. Aims & Objective: To study the prevalence of overweight and obesity & its correlates among school going adolescents of Haldwani block. Material & Methods: School based cross sectional study was done among the adolescents of 8th to 12th standard. To calculate the maximum sample size prevalence of obesity was assumed to be 50%, taking absolute error of 5%, design effect of 2 and 10% non-response rate the sample was calculated to be 880, rounded off to 900. Samples were collected from 30 clusters/schools using simple random sampling. Data was collected using a pre-designed, semi-structured and pre-tested questionnaire and analyzed by using SPSS version 22. Results: Prevalence of overweight and obesity was 13% (CI = 10.8 - 15.2%. Overweight and obesity was found to be significantly associated with urban area, private school, Socio-economic class I, non-vegetarian diet, physical inactivity and playing videogames, working on laptops and computer on univariate analysis. On applying binary logistic regression factors like private schools, socioeconomic class I, non-vegetarian diet and physical inactivity were again found to be significantly associated with overweight and obesity. Conclusion: Prevalence of obesity was found to be more in adolescents having modifiable risk factors.

Full Text Available OBJECTIVE: To assess the association between regular physical activity in adolescence and leisure-time physical activity in adulthood, with emphasis on gender differences. METHODS: A population-based cross-sectional study was carried out in Pelotas, Southern Brazil, in 2003. A representative sample of households was selected in multiple stages and subjects aged 20-59 years were interviewed. Leisure-time physical activity was evaluated using the International Physical Activity Questionnaire. Data on adolescent physical activity were based on subjects' recall. RESULTS: Of 2,577 subjects interviewed, 27.5% were classified as adequately active, and 54.9% reported regular physical activity in adolescence. Subjects who engaged in regular physical activity during adolescence were more likely to be adequately active in adulthood (adjusted prevalence ratio 1.42; 95% CI: 1.23; 1.65. This effect was stronger in women (adjusted prevalence ratio: 1.51; 95% CI: 1.22; 1.86 than men (adjusted prevalence ratio: 1.35; 95% CI: 1.10; 1.67. CONCLUSIONS: Promoting physical activity in school age may be a successful intervention against the epidemic of adult inactivity. Although women were less likely to report regular physical activity in adolescence, the effect of this experience on adult behavior was stronger than in men.OBJETIVO: Avaliar a associação entre a prática de atividades físicas sistematizadas na adolescência e o nível de atividade física no lazer na idade adulta, com ênfase nas diferenças quanto ao gênero.

The high availability and accessibility of online gambling have recently caused public concern regarding the potential increase of gambling-related problems among young people. Nonetheless, few studies among adults and none among adolescents have explored specific characteristics of gamblers as a function of gambling venues to date. This study sought to analyze the prevalence of gambling among a sample of adolescents in the last year, as well as sociodemographic and gambling-related characteristics as possible predictors of at-risk and problem gambling. The sample comprised 1313 adolescents aged 14-18 years. Participants were asked to respond to several questions regarding their gambling behavior. Chi square and ANOVA tests were performed in order to explore differences between groups, and a set of multinomial regressions established significant severity predictors. The prevalence of at-risk and problem gambling was 4 and 1.2 %, respectively. Regression analyses showed that having a relative with gambling problems predicted at-risk gambling. Both living with only one parent or not living with parents at all, and the prevalence of Electronic Gambling Machines in the last year were associated with problem gambling. Mixed-mode gambling was a predictor of both at-risk and problem gambling. Our findings extend previous research on gambling among adolescents by exploring gambling behavior according to different modes of access. Although the prevalence of exclusive online gambling among the total sample was low, these results support the need to consider specific subgroups of gamblers and their concrete related features when conducting both indicated prevention and treatment protocols for adolescents.

The fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) includes a considerably revised eating disorder section. The aim of this study was to establish the prevalence and severity of eating disorders based on the new DSM-5 criteria in a community cohort of adolescents. This study is part of TRAILS (TRacking Adolescents' Individual Lives Survey), a Dutch cohort study on mental health and social development from preadolescence into young adulthood. At baseline, the participants (n = 2,230) were about 11 years old. Body mass index was measured at all four assessment waves. At age 19, the Composite International Diagnostic Interview was administered to 1,584 of the participants. A two-stage screening approach was used to estimate the prevalence of DSM-5 eating disorders. Adolescents at high risk for eating disorders (n = 312) were selected for an additional interview administered by eating disorder experts. Of the high-risk group n = 296 (95%) could be interviewed. Among the women, the lifetime prevalence of DSM-5 anorexia nervosa was 1.7%, of bulimia nervosa 0.8% and of binge eating disorder 2.3%. Eating disorders were relatively rare among the men. The severity of most cases was mild to moderate and detection and treatment rates depended on the level of severity. The most common DSM-5 eating disorder diagnoses in adolescents in the community are anorexia nervosa and binge eating disorder. Severity ratings for eating disorders seem valid in terms of both the distribution in the community and the correlation with detection and treatment by health care services. © 2014 Wiley Periodicals, Inc.

Factors Influencing the Prevalence of Animal Cruelty During Adolescence.

Connor, M; Currie, C; Lawrence, A B

2018-04-01

Adolescents' interactions with animals are of increasing interest and their beneficial developmental outcomes are well known. However, negative interactions such as perpetrating cruelty toward animals during childhood and adolescence have been related with child abuse, domestic violence, and later interpersonal violence. Cruelty toward animals by adolescents has been reported predominately in criminal and clinical samples, and links have been made between animal cruelty and interpersonal violence. However, studies often lack a clear definition of animal cruelty and the animal involved. The present study addresses methodological shortcomings by providing a clear definition of the cruelty acts and the animals involved and the time frame within which cruelty acts have been taken place. Therefore, we investigated the prevalence of animal cruelty of 979 British adolescents (419 male, 497 female, M age = 15.1 ± 1.57 years) by means of a survey questionnaire administered in school. Animal cruelty was investigated encompassing deliberate and nondeliberate cruelty acts, a clear definition of the target animals was included and a time frame was provided. Furthermore, acceptability of animal cruelty, engaging in antisocial behavior, and family affluence were investigated. Results show high reliabilities for the measures applied. Exploratory factor analysis reveals different types of animal cruelty. Gender differences were observed for deliberate and accidental cruelty acts, with boys reporting higher levels than girls. Younger adolescents reported higher accidental cruelty acts than older ones. Acceptance of animal cruelty played a significant role in predicting animal cruelty, together with antisocial behaviors and place of living. The present study shows for the first time the importance of distinguishing between different types of animal cruelty and defining the animals involved.

The previous literature about comorbidity between eating disorders (ED) and other DSM-IV psychiatric disorders in adolescence has employed cross-sectional studies with clinical samples, where the comorbid disorders were diagnosed retrospectively. The present study aims to overcome these limitations by the analysis of comorbidity in a community population during 2-year follow-up. A semi-structured interview was applied to a teenager sample. Firstly, a cross-sectional and non-randomized study on psychiatric morbidity was conducted with 993 teenagers between the ages of 12 and 16 from five schools. Secondly, 326 students between 14 and 17 years old of one school were reassessed 2 years later in order to detect ED new cases and find associations with previous psychiatric disorders. The ED prevalence was 3.6%. Cross-sectional analysis revealed that 62.9% of individuals with an ED had comorbid disorders: anxiety disorders (51.4%), Attention Deficit Hyperactivity Disorder (31.4%), oppositional defiant disorder (11.4%), and obsessive compulsive disorder (8.6%). Prospective longitudinal analysis showed an ED incidence rate of 2.76% over the course of 2 years. 22.2% of new cases had received previous psychiatric diagnoses, of which all were anxiety disorders. Thus, ED exhibited a high comorbidity rate among adolescent populations and anxiety disorders were the most common comorbid diagnosis. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Full Text Available This study was conducted to estimate the prevalence and associated factors of subjective halitosis in adolescents. In total, 359,263 participants were selected from the Korea Youth Risk Behavior Web-based Survey (KYRBWS from 2009 through 2013. Demographic data including age, sex, obesity and residency; psychosocial factors such as subjective health, stress, and economic levels; and dietary factors such as alcohol consumption; smoking; and fruit, soda, fast food, instant noodle, confection, and vegetable consumption were analyzed for correlations with halitosis using simple and multiple logistic regression analyses with complex sampling. In total, 23.6% of the participants reported the presence of halitosis. The following subjectively assessed factors were related to halitosis: poor health status (adjusted odds ratio [AOR] = 2.56, overweight or obese (AOR = 1.37, stress (AOR = 2.56, and lower economic levels (AOR = 1.85. The high intake of fast food (AOR = 1.15, instant noodles (AOR = 1.17, and confections (AOR = 1.17 and the low intake of fruits (AOR = 1.22 and vegetables (AOR = 1.19 were also related to halitosis. The prevalence of subjective halitosis in the studied adolescents was 23.6%. Specific psychosocial factors and dietary intake were related to halitosis.

The aim of this study is to examine the prevalence and correlates of adolescents' resistance training (RT) skill competence. Participants were 548 adolescents (14.1 ± 0.5 years) from 16 schools in New South Wales, Australia. RT skills were assessed using the Resistance Training Skills Battery. Demographics, BMI, muscular fitness, perceived strength, RT self-efficacy, and motivation for RT were also assessed. The proportion demonstrating "competence" and "near competence" in each of the six RT skills were calculated and sex differences explored. Associations between the combined RT skill score and potential correlates were examined using multi-level linear mixed models. Overall, the prevalence of competence was low (range = 3.3% to 27.9%). Females outperformed males on the squat, lunge and overhead press, whereas males performed better on the push-up (p fitness was moderately and positively associated with RT skills among both males (β = 0.34, 95%CIs = 0.23 to 0.46) and females (β = 0.36, 95%CIs = 0.23 to 0.48). Our findings support a link between RT skills and muscular fitness. Other associations were statistically significant but small in magnitude, and should therefore be interpreted cautiously.

Major Depressive Disorder (MDD) among youth is a public health concern. Our aim was to examine the current body of knowledge to better characterize the prevalence and morbidity associated with subthreshold forms of MDD among youth. Given that MDD tends to develop gradually over time, we hypothesized a high prevalence and considerable impairment associated with youth suffering from depressive symptoms that fall short of full, syndromic status. A literature search was conducted using PubMed exclusively to identify studies assessing the prevalence and clinical characteristics of subthreshold MDD in adolescents. Six scientific papers that met our priori inclusion and exclusion criteria were identified. All papers sampled adolescents. The prevalence of subthreshold MDD ranged from 5% over the past year, to 29% over the two weeks prior to screening. These papers reported clinically significant morbidity associated with subthreshold MDD among adolescents, with evidence for elevated rates of psychiatric comorbidities, impaired functioning in social and familial domains, increased suicidality, and frequent mental health service utilization. Though we examined a sizeable and diverse sample, we only identified six cross-sectional informative studies for this review. Variability of subthreshold MDD and major outcome definitions across studies, likely limits the specificity of findings. Subthreshold MDD is prevalent among youth, and is associated with emotional and social impairments that reach the level of obtaining clinical care. These findings could lead to early intervention efforts aimed at mitigating the adverse outcomes associated with subthreshold MDD as well as the progression to full syndrome MDD. Our review documents that regardless of whether progression to full diagnostic status occurs, this condition is morbid. Copyright © 2016 Elsevier B.V. All rights reserved.

BaCKGROUND. The prevalence of dental erosion seems to be rising in young populations, particularly among individuals of higher socioeconomic status. AIM. To assess the prevalence and associated factors of dental erosion in children and adolescents of a private dental practice. DESIGN. A total of 232 participants, aged 2-20 years, were examined. Dietary habits, oral hygiene, and medical data were collected from dental records. Logistic regression analyses were conducted. RESULTS. Dental erosion prevalence was of 25.43% and was highest on the occlusal surfaces (76%). Associated factors were: frequent consumption of soft drinks (OR = 2.33; 95% CI = 1.01-5.38) and candies (OR = 3.23; 95% CI = 1.25-8.32); and interaction between these two factors (OR = 3.95; 95% CI = 1.60-9.75). On anterior teeth, associated factors were: frequent consumption of fruits (OR = 2.53; 95% CI = 1.09-5.91); and age (OR = 1.07 95% CI = 1.01-1.14). Milk consumption was associated with a lower prevalence of dental erosion (OR = 0.40; 95% CI = 0.17-0.94). CONCLUSIONS.  A relatively high prevalence of erosion was found in association with frequent intake of soft drinks, candies, and fruits. The consumption of milk seemed to protect against dental erosion on anterior teeth. © 2011 The Authors. International Journal of Paediatric Dentistry © 2011 BSPD, IAPD and Blackwell Publishing Ltd.

Dietary habits in the Mexican population have changed dramatically over the last few years, which are reflected in increased overweight and obesity prevalence. The aim was to examine the prevalence of metabolic syndrome (MetS) and associated risk factors in Northern Mexican adults aged ≥ 16 years. The study was a population-based cross-sectional nutritional survey carried out in the State of Nuevo León, Mexico. The study included a sub-sample of 1,200 subjects aged 16 and over who took part in the State Survey of Nutrition and Health-Nuevo León 2011/2012. Anthropometric measurements, physical activity, blood pressure and fasting blood tests for biochemical analysis were obtained from all subjects. The prevalence of MetS in Mexican adults aged ≥ 16 years was 54.8%, reaching 73.8% in obese subjects. This prevalence was higher in women (60.4%) than in men (48.9%) and increased with age in both genders. Multivariate analyses showed no evident relation between MetS components and the level of physical activity. Obese adults, mainly women, are particularly at risk of developing MetS, with the associated implications for their health. The increasing prevalence of MetS highlights the need for developing strategies for its early detection and prevention.

Children with Down syndrome (DS) are more likely to be overweight or obese than the general population of youth without DS. To review the prevalence of overweight and obesity and their determinants in youth with DS. The health consequences and the effectiveness of interventions were also examined. A search using MEDLINE, Embase, Web of Science, Scopus, CINAHL, PsycINFO, SPORTDiscus, LILACS, and COCHRANE was conducted. From a total of 4280 studies, we included 45 original research articles published between 1988 and 2015. The combined prevalence of overweight and obesity varied between studies from 23% to 70%. Youth with DS had higher rates of overweight and obesity than youths without DS. Likely determinants of obesity included increased leptin, decreased resting energy expenditure, comorbidities, unfavorable diet, and low physical activity levels. Obesity was positively associated with obstructive sleep apnea, dyslipidemia, hyperinsulinemia, and gait disorder. Interventions for obesity prevention and control were primarily based on exercise-based programs, and were insufficient to achieve weight or fat loss. Population-based research is needed to identify risk factors and support multi-factorial strategies for reducing overweight and obesity in children and adolescents with DS.

The aim of the current study was to establish the prevalence of subthreshold body dysmorphic disorder (subthreshold-BDD) in a community sample of adolescents, and to compare disorder correlates in individuals with subthreshold-BDD to those with probable full-syndrome BDD (probable-BDD) and those without BDD (non-BDD). Self-report questionnaires assessing DSM-IV BDD criteria, past mental health service use, and symptoms of body dysmorphic disorder, anxiety, depression, obsessive-compulsive disorder and eating disorders, were completed by 3149 Australian high school students (mean age =14.6 years, 63.5% male). Male participants also completed measures assessing quality of life, muscularity concerns, emotional symptoms, conduct problems, hyperactivity, and peer problems. The prevalence of subthreshold-BDD was 3.4%, and probable-BDD was 1.7%. Compared to the non-BDD group, subthreshold-BDD was associated with elevated symptoms of comorbid psychopathology and greater past mental health service use, and in male-only measures, with poorer quality of life and elevated muscularity concerns. Subthreshold-BDD participants reported significantly lower mental health service use, and fewer symptoms of depression, eating disorders, and hyperactivity than probable-BDD participants, however, other comorbid symptoms did not differ significantly between these groups. These findings indicate that subthreshold-BDD is associated with substantial difficulties for adolescents in the general community. BDD screening should include subthreshold presentations, as these may be an important target for early intervention programs. Copyright © 2017 Elsevier Ireland Ltd. All rights reserved.

Sexual activity during adolescence can lead to unwanted pregnancy, which in turn can result in serious maternal and fetal complications. The present study aimed to evaluate the complications related to adolescent pregnancy, through a systematic review using the Medical Subject Headings: "pregnancy complication" AND "adolescent" OR "pregnancy in adolescence". Only full original articles in English or Portuguese with a clearly described methodology, were included. No qualitative studies, reviews or meta-analyses, editorials, case series, or case reports were included. The sample consisted of 15 articles; in that 10 were cross-sectional and 5 were cohort studies. The overall prevalence of adolescent pregnancy was 10%, and among the Brazilian studies, the adolescent pregnancy rate was 26%. The cesarean delivery rate was lower than that reported in the general population. The main maternal and neonatal complications were hypertensive disorders of pregnancy, prematurity and low birth weight, respectively. Adolescent pregnancy is related to increased frequency of neonatal and maternal complications and lower prevalence of cesarean delivery.

Psychotherapeutic approaches to non-suicidal self-injury in adolescents

2012-03-01

Full Text Available Abstract Non-suicidal self-injury (NSSI among adolescents is gaining increasing attention in both clinical and scientific arenas. The lifetime prevalence of NSSI is estimated to vary between 7.5% to 8% for preadolescents, increasing to between 12% and 23% for adolescents. Despite the prevalence and the increasing interest in NSSI, few psychotherapeutic treatments have been designed specifically for NSSI, and no treatments have been evaluated specifically for the treatment of NSSI among adolescents. Consequently, child and adolescent clinicians are left with little evidence-based guidance for treating this challenging population. To provide some guidance, evaluations of treatments for adults with NSSI and for adolescents with related conditions, such as deliberate self-harm and borderline personality disorder, are reviewed. Clinical guidelines and resources are also discussed to assist with the gaps in the knowledge base for treatment of NSSI among adolescents.

Full Text Available Abstract Background Obesity is a one of the most common nutritional disorder worldwide, clearly associated with the metabolic syndrome, condition with implications for the development of many chronic diseases. In the poorest countries of Latin America, malnourishment is still the most prevalent nutritional problem, but obesity is emerging in alarming rates over the last 10 years without a predictable association with metabolic syndrome. The objective of our study was to determine the association between insulin-resistance and components of the metabolic syndrome in a group of Bolivian obese children and adolescents. The second objective was determining the relation of acanthosis nigricans and insulin-resistance. Methods We studied 61 obese children and adolescents aged between 5 and 18 years old. All children underwent an oral glucose tolerance test and fasting blood sample was also obtained to measure insulin, HDL, LDL and triglycerides serum level. The diagnosis of metabolic syndrome was defined according to National Cholesterol Education Program-Adult Treatment Panel (NCEP-ATP III criteria adapted for children. Results Metabolic syndrome was found in 36% of the children, with a higher rate among males (40% than females (32.2% (p = 0.599. The prevalence of each of the components was 8.2% in impaired glucose tolerance, 42.6% for high triglyceride level, 55.7% for low levels of high-density lipoprotein cholesterol, and 24.5% for high blood pressure. Insulin resistance (HOMA-IR > 3.5 was found in 39.4% of the children, with a higher rate in males (50% than females (29%. A strong correlation was found between insulin resistance and high blood pressure (p = 0.0148 and high triglycerides (p = 0.002. No statistical significance was found between the presence of acanthosis nigricans and insulin resistance. Conclusion Metabolic syndrome has a prevalence of 36% in children and adolescent population in the study. Insulin resistance was very common among

To describe clinical and epidemiological features of children and adolescents with interdisciplinary diagnosis of non-verbal learning disorder and to investigate the prevalence of inter-hemispheric asymmetry in this population group. Cross-sectional study including children and adolescents referred for interdisciplinary assessment with learning difficulty complaints, who were given an interdisciplinary diagnosis of non-verbal learning disorder. The following variables were included in the analysis: sex-related prevalence, educational system, initial presumptive diagnoses and respective prevalence, overall non-verbal learning disorder prevalence, prevalence according to school year, age range at the time of assessment, major family complaints, presence of inter-hemispheric asymmetry, arithmetic deficits, visuoconstruction impairments and major signs and symptoms of non-verbal learning disorder. Out of 810 medical records analyzed, 14 were from individuals who met the diagnostic criteria for non-verbal learning disorder, including the presence of inter-hemispheric asymmetry. Of these 14 patients, 8 were male. The high prevalence of inter-hemispheric asymmetry suggests this parameter can be used to predict or support the diagnosis of non-verbal learning disorder.

Economic and dietary changes in the Indian state of Tamil Nadu have led to compromised oral health status of the adolescent population. Adequate epidemiological data are not available to address the prevention or treatment needs in this region of India. The aim of this study was to measure the prevalence and severity of dental caries among adolescents of Tamil Nadu, a southern state of India. The study sample included 974 adolescent school students (12-15 years of age) from both rural and urban areas of Tamil Nadu, India. The decayed, missing and filled teeth (DMFT) index of these students was measured using the World Health Organization oral health survey method, in a quantitative cross-sectional study. The oral health survey indicated that the prevalence of dental caries among adolescents in rural and urban areas of Tamil Nadu was 61.4%, with an average DMFT score of 2.03. Multiple regression analyses indicated factors such as gender, mother's education, type of school and caste as significant predictors of dental caries. Female gender, Scheduled Caste and Tribes attending public schools in rural areas were identified as the more vulnerable populations to be affected by dental caries. Oral health policies should be targeted to these adolescent populations in the Tamil Nadu region. © 2016 FDI World Dental Federation.

To analyze prevalence and factors associated with stages of behavior change for physical activity in adolescents. A search was performed in SciELO, PubMed, PsycINFO, SPORTDiscus and LILACS. The search terms were "behavior change" OR "stages of change" OR "stages of readiness" OR "readiness to change" OR "transtheoretical model" OR "process to change" OR "decisional balance", and "motor activity" OR "physical activity" OR "physical exercise" and "adolescent" OR "students". After the eligibility criteria, 18 articles were selected. The highest prevalence of adolescents in the precontemplation, contemplation, and preparation stages was found in the Germany, South Korea, and Iran while there were more adolescents in the action and maintenance in South Korea and Brazil. The evidence of association indicated that females are more likely to be in precontemplation, contemplation and preparation. The evidence was inconclusive for age (in relation to the precontemplation, contemplation, action and maintenance stages), economic status (all stages), shift of study (when stratified by gender) and body composition (all stages). No association was found with parental level of education. The findings can help to guide interventions and further research on the topic of behavior changes for physical activity in adolescents.

This paper aims to describe the prevalence of parent-adolescent conversations about eating, physical activity and weight across sociodemographic characteristics and to examine associations with adolescent BMI, dietary intake, physical activity and sedentary behaviors. Data from two linked epidemiological studies were used for cross-sectional analysis. Parents (n=3,424; 62% females) and adolescents (n=2,182; 53.2% girls) were socioeconomically and racially/ethnically diverse. Fathers reported more parent-adolescent conversations about healthful eating and physical activity with their sons and mothers reported more weight-focused conversations with their daughters. Parents of Hispanic/Latino and Asian/Hmong youth and parents from lower SES categories engaged in more conversations about weight and size. Adolescents whose mothers or fathers had weight-focused conversations with them had higher BMI percentiles. Adolescents who had two parents engaging in weight-related conversations had higher BMI percentiles. Healthcare providers may want to talk about the types of weight-related conversations parents are having with their adolescents and emphasize avoiding conversations about weight specifically.

Full Text Available Objectives: Given the paucity of research on adolescent ADHD, this study aimed to establish the prevalence of DSM-IV ADHD in a cohort of South African adolescents who had been diagnosed with the disorder in childhood. It also aimed to establish the prevalence of psychiatric comorbidities and adjustment difficulties in this sample. Method: Data regarding age of diagnosis, current ADHD status, current ADHD-related pharmacological management, current psychopathology and current adjustment were gathered from 64 adolescents and their guardians via self-report questionnaire. Descriptive statistics were calculated with regard to current ADHD status, comorbid psychopathology and adjustment difficulties, as well as current ADHD-related medication. Results: According to parent reports, 59.38% of the sample met DSM-IV criteria for ADHD Inattentive subtype, while 37.50% met the criteria for ADHD Hyperactive/Impulsive subtype. Approximately sixty-four percent (64.06% of the adolescents were still using stimulant medication. Based on the adolescent self-report, 43.75% of the sample reported clinically significant symptoms of psychopathology or maladjustment. Furthermore, 39.28% of the adolescents met the diagnostic criteria for at least one psychiatric comorbidity. Conclusion: ADHD did persist into adolescence in the current sample. A significant psychopathological and maladjustment load appears evident amongst adolescents previously diagnosed with ADHD despite continuous pharmacological management of the condition.

Although prevalence and incidence of type 2 diabetes mellitus (T2DM) are reportedly increasing among adolescents, national data are lacking, particularly in regard to undiagnosed T2DM. To estimate the prevalence of diagnosed and undiagnosed T2DM among US adolescents, we analyzed a nationally representative cross-section of 11,888 adolescents aged 12-19 years who received a diabetes interview in the Continuous National Health and Nutrition Examination Survey during 1999-2010. Among them, a random subsample of 4,661 adolescents also had fasting blood samples collected. Persons who reported a previous diabetes diagnosis and were either taking no medication or taking an oral hypoglycemic agent (with or without insulin) were classified as having T2DM; persons who reported using insulin alone were classified as having type 1 diabetes. Undiagnosed diabetes was defined as a fasting plasma glucose concentration of ≥126 mg/dL and was assumed to be type 2. In the fasting subsample, 31 diabetes cases (types 1 and 2) were identified, representing a prevalence of 0.84% (weighted 95% confidence interval (CI): 0.51, 1.40) (276,638 cases; 95% CI: 134,255, 419,020). Estimates of the prevalences of type 1 and type 2 diabetes were 0.48% (95% CI: 0.23, 1.02) and 0.36% (95% CI: 0.20, 0.67), respectively, indicating that T2DM accounted for 43% of all cases. Further, undiagnosed T2DM prevalence was 0.12% (95% CI: 0.05, 0.31), representing 34% of T2DM cases (40,611 cases; 95% CI: 2,850, 78,373). T2DM accounts for approximately half of adolescent diabetes in the United States, and one-third of these cases are undiagnosed.

Background: The prevalence of temporomandibular disorder (TMD) in children and adolescents is in the range of 6-68% and can be triggered or aggravated by emotional stress. Aim: The study was to investigate the prevalence of TMD in Portuguese children and adolescents and its association with emotional stress. Materials and Methods: The sample comprised 3,260 students aged 5-19 years. The questionnaire was used to assess the presence of TMD, and was applied in a single moment. Results: TMD was observed in 821 (25.2%) students. The most common symptoms of TMD were: if considered tense or nervous (52%), have headaches (36.8%), and habit of clenching or grinding teeth (27.3%). The girls had a 1.36 higher probability of developing TMD than boys (95% CI: 1.14-1.63; p < 0.001); moreover, students from the older age group had a 2.31 higher probability of developing the disorder (95% CI: 1.85-2.89; p < 0.001). Students who considered themselves tense or nervous presented 8.74 higher probability (95% CI: 7.03-10.86; p < 0.001) of developing TMD. Conclusion: This study showed a high prevalence of TMD in children and adolescents in southern Portugal, and revealed a significant association between this dysfunction and the levels of emotional stress. Female students, older students, and those considered tense or nervous have a higher probability of developing TMD. PMID:24741551

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.

Methods: The study population was a sample of 512 students of secondary education (high school from 3 public schools in Milan, Italy. Two hundred and fourty-nine boys and 263 girls aged 15 to 21 years old (M = 16.2, SD = 2.1 answered a specially structured anonymous questionnaire. Results: Recent problem drinking (‘every day’ or ‘once a week’ was reported from 9% (‘wine’ up to 28% (‘beer’ of students. Cannabis and rave drugs usage (ranged from ‘every day’ to ‘once only in a while’ were reported by up to 38% (‘cannabis’ and 2% (‘rave drugs’ of students. Beer was the most popular type of alcoholic beverage (81% with respect to wine (62% and hard liquor (66%. Only a small percentage of participants stated that they were informed about the possible addiction to alcohol (5% and its negative social consequences (3%. Nevertheless, almost all the students (92% declared that alcohol consumption was less dangerous than other psychoactive substances. Finally, most students stated to know DFSA phenomenon (77% and were victims or witness (13% of a DFSA event. Conclusion: Psychoactive substances consumption remains a serious problem among Italian adolescents. For a successful alcohol strategy there is a need to implement preventive measures and counseling approaches in school. Increasing the knowledge of the negative effects of alcohol/drugs use might also lead to a better prevention of the DFSA phenomenon.

To document the prevalence of harassment on the basis of weight, race/ethnicity, and socioeconomic status, as well as sexual harassment, among a diverse population of adolescents. Specifically, this study examined rates of each type of harassment reported across groups within the corresponding sociodemographic category (e.g., racial/ethnic category differences in prevalence of racial harassment), and also explored patterns of "cross-harassment" (i.e., differences in prevalence of each harassment type across all other sociodemographic characteristics). We used data from Project Eating and Activity in Teens 2010 for the study. The sample was composed of 2,793 adolescents (53% female; 81% nonwhite). We conducted regression analyses to yield prevalence estimates of each type of harassment in each demographic and body mass index category. Weight- and race-based harassment (35.3% and 35.2%, respectively) was most prevalent, followed by sexual harassment (25.0%) and socioeconomic status-based harassment (16.1%). Overweight and obese adolescents reported disproportionately higher rates of all forms of harassment than did normal-weight and underweight adolescents. In addition, Asian and mixed-/other race adolescents were more vulnerable to harassment overall compared with those from other racial/ethnic groups. Harassment experiences are prevalent among adolescent boys and girls. Differential rates of each type of harassment are reported across groups within the corresponding sociodemographic category, but a pattern of cross-harassment also is evident, such that differences in prevalence of each type of harassment emerge across a variety of sociodemographic characteristics. Adolescents from various intersecting sociodemographic and weight-status groups are particularly vulnerable to certain types of harassment.

Evidence indicates that central adiposity has increased to a higher degree than general adiposity in children and adolescents in recent decades. However, waist circumference is not a routine measurement in clinical practice. This study aimed to determine the prevalence of abdominal obesity based on waist circumferences (WC) and waist to height ratio (WHtR) in Spanish children and adolescents aged 6 to 17 years. Further, the prevalence of abdominal obesity (AO) among normal and overweight individuals was analyzed. Data were obtained from a study conducted from 1998 to 2000 in a representative national sample of 1521 children and adolescents aged 6 to 17 years (50.0% female) in Spain. WC and WHtR measurements were obtained in addition to BMI. AO was defined as WHtR ≥0.50 (WHtR-AO), sex and age specific WC≥90(th) percentile (WC-AO1), and sex and age specific WC cut-off values associated with high trunk fat measured by by dual-energy X-ray absorptiometry (WC-AO2). IOTF- based overweight and obsity prevalence was 21.5% and 6.6% in children and 17.4% and 5.2% in adolescents, respectively. Abdominal obesity (AO) was defined as WHtR≥0.50 (WHtR-AO), sex- and age-specific WC≥90th percentile (WC-AO1), and sex- and age-specific WC cut-off values associated with high trunk fat measured by dual-energy X-ray absorptiometry (WC-AO2). The respective prevalence of WHtR-AO, WC-AO1, and WC-AO2 was 21.3% (24.6% boys; 17.9% girls), 9.4% (9.1% boys; 9.7% girls), and 26.8% (30.6% boys;22.9% girls) in children and 14.3% (20.0% boys; 8.7% girls), 9.6% (9.8% boys; 9.5% girls), and 21.1% (28.8% boys; 13.7% girls) in adolescents. The prevalence of AO in Spanish children and adolescents is of concern. The high proportion of AO observed in young patients who are normal weight or overweight indicates a need to include waist circumference measurements in routine clinical practice.

Thinness in children and adolescents is largely under studied, a contrast with abundant literature on under-nutrition in infants and on overweight in children and adolescents. The aim of this study is to compare the prevalence of thinness using two recently developed growth references, among children and adolescents living in the Seychelles, an economically rapidly developing country in the African region. Weight and height were measured every year in all children of 4 grades (age range: 5 to 16 years) of all schools in the Seychelles as part of a routine school-based surveillance program. In this study we used data collected in 16,672 boys and 16,668 girls examined from 1998 to 2004. Thinness was estimated according to two growth references: i) an international survey (IS), defining three grades of thinness corresponding to a BMI of 18.5, 17.0 and 16.0 kg/m2 at age 18 and ii) the WHO reference, defined here as three categories of thinness (-1, -2 and -3 SD of BMI for age) with the second and third named "thinness" and "severe thinness", respectively. The prevalence of thinness was 21.4%, 6.4% and 2.0% based on the three IS cut-offs and 27.7%, 6.7% and 1.2% based on the WHO cut-offs. The prevalence of thinness categories tended to decrease according to age for both sexes for the IS reference and among girls for the WHO reference. The prevalence of the first category of thinness was larger with the WHO cut-offs than with the IS cut-offs while the prevalence of thinness of "grade 2" and thinness of "grade 3" (IS cut-offs) was similar to the prevalence of "thinness" and "severe thinness" (WHO cut-offs), respectively.

Childhood Experiences of Adolescents in Boarding Schools. A Comparison with Adolescents in Residential Care and with the General Population Various studies indicate that students in boarding schools experience a lot of violence during their accommodation. However, it is not proved whether adolescents in boarding schools are also a burdensome group regarding early childhood experiences such as neglect and abuse. The aim of the study was to find out more about the experiences of adolescents in boarding schools and to determine whether there are differences between adolescents in residential care and between the general population. Furthermore, it should be examined whether boys and girls differ in their experiences. In the study, adolescents of boarding schools and of residential care all over Germany, starting at the age of 15 (n = 322), were asked regarding physical and emotional neglect/abuse, light/severe parent violence, negative/positive educational behavior of the parents. The results show that students in boarding schools were less likely to be affected by childhood maltreatment and more likely to have experienced positive parental behavior compared to children in residential care. Compared to the general population, students in boarding schools were more often and more severely affected by parental violence. Moreover, girls had experienced parental violence more often than boys. The results indicate that in boarding schools there is a need for support offers for adolescents with a history of violent experiences and that the risk group should be identified directly at the admission to the school.

Prevalence of intestinal parasitic infections in the population of Central Asia on the example of inhabitants of Eastern Afghanistan

Science.gov (United States)

Korzeniewski, Krzysztof

Parasitic diseases of the gastrointestinal tract are a major health problem worldwide, especially in the Third World countries, where poor standards of hygiene and sanitation as well as the lack of medical care facilitate the spread of food and waterborne infections. To estimate the prevalence of intestinal parasitic infections in Central Asia on the example of the population inhabiting the Ghazni Province in eastern part of the country and to assess the validity of the WHO recommended mass deworming campaign carried out in Afghanistan. Taking into consideration the fact that hundreds of thousands of immigrants from Asia and Africa have recently been flooding into Europe, it has become necessary to investigate the epidemiology of intestinal parasitoses in areas characterized by different climatic conditions and poor standards of sanitation. The study was conducted in eastern Afghanistan between November 2011 and April 2014. Parasitological examination was performed on 3 different study groups: 110 soldiers from the Afghan National Army (adults), 1,167 patients hospitalized at the Ghazni Provincial Hospital (807 children and adolescents aged 1–18 and 360 adults), and 1,869 students (7–18 years) frequenting local schools. The study involved 3,146 people including: 2,248 females and 898 males; 2,676 children and adolescents (1–18 years) and 460 adults (19–85 years). Three stool samples were collected from each study subject at the intervals of 2 to 3 days. The samples were fixed in 10% formalin and then transported by air to the Department of Epidemiology and Tropical Medicine (Military Institute of Medicine) in Poland, where they were examined by light microscopy using 3 different diagnostic methods (direct smear in Lugol’s solution, decantation with distilled water, Fülleborn’s flotation). In total, 1,220 Afghans were found to be infected with pathogenic intestinal parasites (38.8%): 44/110 soldiers (40.0%), 322/807 hospitalized children and adolescents

Full Text Available This study aimed to monitor diet quality and associated factors in adolescents, adults and older adults from the city of São Paulo, Brazil. We conducted a cross-sectional population-based study involving 2376 individuals surveyed in 2003, and 1662 individuals in 2008 (Health Survey of São Paulo, ISA-Capital. Participants were of both sexes and aged 12 to 19 years old (adolescents, 20 to 59 years old (adults and 60 years old or over (older adults. Food intake was assessed using the 24-h dietary recall method while diet quality was determined by the Brazilian Healthy Eating Index (BHEI-R. The prevalence of descriptive variables for 2003 and 2008 was compared adopting a confidence interval of 95%. The means of total BHEI-R score and its components for 2003 and 2008 were compared for each age group. Associations between the BHEI-R and independent variables were evaluated for each survey year using multiple linear regression analysis. Results showed that the mean BHEI-R increased (54.9 vs. 56.4 points over the five-year period. However, the age group evaluation showed a deterioration in diet quality of adolescents, influenced by a decrease in scores for dark-green and orange vegetables and legumes, total grains, oils and SoFAAS (solid fat, alcohol and added sugar components. In the 2008 survey, adults had a higher BHEI-R score, by 6.1 points on average, compared to adolescents. Compared to older adults, this difference was 10.7 points. The diet quality remains a concern, especially among adolescents, that had the worst results compared to the other age groups.

Clinicopathological significance of psychotic experiences in non-psychotic young people: evidence from four population-based studies.

LENUS (Irish Health Repository)

2012-07-01

Epidemiological research has shown that hallucinations and delusions, the classic symptoms of psychosis, are far more prevalent in the population than actual psychotic disorder. These symptoms are especially prevalent in childhood and adolescence. Longitudinal research has demonstrated that psychotic symptoms in adolescence increase the risk of psychotic disorder in adulthood. There has been a lack of research, however, on the immediate clinicopathological significance of psychotic symptoms in adolescence.

To describe prevalence of anisometropia, defined in terms of both sphere and cylinder, examined cross-sectionally, in school-aged members of a Native American tribe with a high prevalence of astigmatism. Cycloplegic autorefraction measurements, confirmed by retinoscopy and, when possible, by subjective refraction were obtained from 1041 Tohono O'odham children, 4 to 13 years of age. Astigmatism > or =1.00 diopter (D) was present in one or both eyes of 462 children (44.4%). Anisometropia > or =1.00 D spherical equivalent (SE) was found in 70 children (6.7%), and anisometropia > or =1.00 D cylinder was found in 156 children (15.0%). Prevalence of anisometropia did not vary significantly with age or gender. Overall prevalence of significant anisometropia was 18.1% for a difference between eyes > or =1.00 D SE or cylinder. Vector analysis of between-eye differences showed a prevalence of significant anisometropia of 25.3% for one type of vector notation (difference between eyes > or =1.00 D for M and/or > or =0.50 D for J0 or J45), and 16.2% for a second type of vector notation (between-eye vector dioptric difference > or =1.41). Prevalence of SE anisometropia is similar to that reported for other school-aged populations. However, prevalence of astigmatic anisometropia is higher than that reported for other school-aged populations.

Alcohol is deleterious to physical and mental health as well as social well-being. This study aims to examine the prevalence of alcohol consumption and factors associated with its use among school-going Malaysian adolescents. The Global School-Based Student Health Survey (GSHS) 2012 employed 2-stage clustering design to Malaysian secondary school respondents aged 12 to 17 years. The prevalence of current alcohol usage was 8.9% (95% confidence interval [CI]: 7.8-10.07) overall, 11.2% (95% CI: 9.80-12.80) among males, and 23.4 (95% CI: 21.40-25.50) among Chinese students. Multivariate logistic regression showed that adolescents who had used alcohol were more likely to have used substance (adjusted odds ratio [aOR] = 3.39; 95% CI: 2.33-4.99), experienced injury (aOR = 1.53; 95% CI: 1.20-1.95), and engaged in sexual behaviors (aOR = 1.42, 95% CI: 1.12-1.79), and fights (aOR = 1.23; 95% CI: 1.08-1.41). The current national policies on alcohol should be strengthened to curb alcohol consumption among adolescents. © 2014 APJPH.

Background and Aims Dietary habits in the Mexican population have changed dramatically over the last few years, which are reflected in increased overweight and obesity prevalence. The aim was to examine the prevalence of metabolic syndrome (MetS) and associated risk factors in Northern Mexican adults aged ≥16 years. Methods and Results The study was a population-based cross-sectional nutritional survey carried out in the State of Nuevo León, Mexico. The study included a sub-sample of 1,200 subjects aged 16 and over who took part in the State Survey of Nutrition and Health–Nuevo León 2011/2012. Anthropometric measurements, physical activity, blood pressure and fasting blood tests for biochemical analysis were obtained from all subjects. The prevalence of MetS in Mexican adults aged ≥16 years was 54.8%, reaching 73.8% in obese subjects. This prevalence was higher in women (60.4%) than in men (48.9%) and increased with age in both genders. Multivariate analyses showed no evident relation between MetS components and the level of physical activity. Conclusions Obese adults, mainly women, are particularly at risk of developing MetS, with the associated implications for their health. The increasing prevalence of MetS highlights the need for developing strategies for its early detection and prevention. PMID:25141255

To describe HIV testing uptake and prevalence among adolescents and adults in a home-based HIV counseling and testing program in western Kenya. Since 2007, the Academic Model Providing Access to Healthcare program has implemented home-based HIV counseling and testing on a large scale. All individuals aged ≥13 years were eligible for testing. Data from 5 of 8 catchments were included in this analysis. We used descriptive statistics and multivariate logistic regression to examine testing uptake and HIV prevalence among adolescents (13-18 years), younger adults (19-24 years), and older adults (≥25 years). There were 154,463 individuals eligible for analyses as follows: 22% adolescents, 19% younger adults, and 59% older adults. Overall mean age was 32.8 years and 56% were female. HIV testing was high (96%) across the following 3 groups: 99% in adolescents, 98% in younger adults, and 94% in older adults (P < 0.001). HIV prevalence was higher (11.0%) among older adults compared with younger adults (4.8%) and adolescents (0.8%) (P < 0.001). Those who had ever previously tested for HIV were less likely to accept HIV testing (adjusted odds ratio: 0.06, 95% confidence interval: 0.05 to 0.07) but more likely to newly test HIV positive (adjusted odds ratio: 1.30, 95% confidence interval: 1.21 to 1.40). Age group differences were evident in the sociodemographic and socioeconomic factors associated with testing uptake and HIV prevalence, particularly, gender, relationship status, and HIV testing history. Sociodemographic and socioeconomic factors were independently associated with HIV testing and prevalence among the age groups. Community-based treatment and prevention strategies will need to consider these factors.

A National Health and Nutrition Survey (ENSANUT) conducted in Mexico in 1999 identified a high prevalence of inadequate mineral intakes in the population by using 24-h recall questionnaires. However, the 1999 survey did not adjust for within-person variance. The 2012 ENSANUT implemented a more up-to-date 24-h recall methodology to estimate usual intake distributions and prevalence of inadequate intakes. We examined the distribution of usual intakes and prevalences of inadequate intakes of calcium, iron, magnesium, and zinc in the Mexican population in groups defined according to sex, rural or urban area, geographic region of residence, and socioeconomic status (SES). We used dietary intake data obtained through the 24-h recall automated multiple-pass method for 10,886 subjects as part of ENSANUT 2012. A second measurement on a nonconsecutive day was obtained for 9% of the sample. Distributions of usual intakes of the 4 minerals were obtained by using the Iowa State University method, and the prevalence of inadequacy was estimated by using the Institute of Medicine's Estimated Average Requirement cutoff. Calcium inadequacy was 25.6% in children aged 1-4 y and 54.5-88.1% in subjects >5 y old. More than 45% of subjects >5 y old had an inadequate intake of iron. Less than 5% of children aged 12 y had inadequate intakes of magnesium, whereas zinc inadequacy ranged from <10% in children aged <12 y to 21.6% in men aged ≥20 y. Few differences were found between rural and urban areas, regions, and tertiles of SES. Intakes of calcium, iron, magnesium, and zinc are inadequate in the Mexican population, especially among adolescents and adults. These results suggest a public health concern that must be addressed. © 2016 American Society for Nutrition.

To report the rate of exposure to different violent events, their demographic correlates, the prevalence of Post-Traumatic Stress Disorder (PTSD), and the impact on quality of life. The National Survey of Psychiatric Epidemiology is representative of the Mexican urban population aged 18 to 65. The survey was undertaken in 2001 and 2002 using the Composite International Diagnostic Interview (CIDI- 15) computerized version. The statistical analyses take into account the multistage, stratified, and weighted sample design. Kaplan-Meier and logistic regressions were performed. Sixty-eight percent of the population has been exposed to at least one stressful life event. Exposure varies by sex (rape, harassment, and sexual abuse are more frequent in women; accidents and being a victim of burglary among men) and by age (more frequent in children, adolescents, young adult women, and the elderly). By sex, 2.3% of women and 0.49% of men present PTSD. Rape, harassment, kidnapping, and sexual abuse are the events most associated with PTSD. The results suggest the need to increase treatment coverage to attend the consequences of violence, taking into consideration the important gender and age variations.

This study provides, for the first time, national population-based estimates describing violence during childhood and adolescence in Peru and the impact on educational outcomes. A population-based school survey was conducted among children aged 9-11 (n=1587) and adolescents aged 12-17 (n=1489). The relationship between violence and educational outcomes were analysed using bivariate logistic regressions, controlling for potential confounding factors. The results show that psychological (75.6%) and physical violence (72.5%) at home were the most prevalent forms of violence experienced by adolescent girls. Adolescent boys reported experiencing similar levels of psychological violence from their peers (69.4%) and at home (68.1%). For the younger cohort, peer-to-peer psychological violence was reported more frequently among girls (70.6%) and boys (74.0%) than other forms of violence. Equal percentages of adolescent girls and boys reported experiencing sexual violence in their lifetime (42.0%). The relationship between violence experiences and educational outcomes varied by gender with strong associations between violence at home and failing a course or repeating a grade for girls and being expelled for boys. Sexual violence experienced by boys was associated with all negative educational outcomes. The relationship between violence in childhood and poorer educational outcomes is multi-faceted, potentially bi-directional, and manifests differently between genders. This research highlights the need for targeted research, policy and programming responses for prevention of violence. © The Author 2016.

To estimate the prevalence of obesity, overweight, abdominal obesity and high blood pressure in a sample of adolescents from a low-income city in Brazil and to estimate the relationship with the socioeconomic status of the family, the education level of the family provider and the type of school. This cross-sectional study randomly sampled 1,014 adolescents (54.8% girls), between 14-19 years of age, attending high school from Imperatriz (MA). The outcomes of this study were: obesity and overweight, abdominal obesity and high blood pressure (systolic and/ or diastolic). The independent variables were: socioeconomic status (SES) of the family, education level of the family provider (ELFP) and type of school. The confounding variables were: gender, age and physical activity level. Prevalence was estimated, and the association between the endpoints and the independent variables was analyzed using a prevalence ratio (PR), with a 95% confidence interval, estimated by Poisson regression. The overall prevalence of obesity was 3.8%, overweight, 13.1%, abdominal obesity, 22.7% and high blood pressure, 21.3%. The adjusted analysis indicated that girls with high SES showed an increased likelihood to be overweight (PR=1.71 [95% IC: 1.13-2.87]), while private school boys had an increased likelihood of obesity (PR=1.79 [95% CI: 1.04-3.08]) and abdominal obesity (PR =1.64 [95% CI: 1.06-2.54]). The prevalence of CVDR is high in adolescents from this low-income region. Boys from private schools are more likely to have obesity and abdominal obesity, and girls with high SES are more likely to be overweight. Copyright AULA MEDICA EDICIONES 2014.

Data obtained from oral health surveys are very important for identifying disease-susceptible groups and for developing dental care and prevention programs. So, the purpose of the current article was to investigate the prevalence of oral mucosa lesions (OMLs) in a population of Brazilian police. Interviews and oral cavity examinations were performed on a sample of 395 police officers who were randomly selected by the calibrated researcher. The number of individuals was obtained by a sample calculation using the finite population correction. The diagnostic criteria were based on the WHO (1997) criteria and adapted to Brazilian surveys. In total, 8.61% of the population presented some OML. Traumatic injuries and benign migratory glossitis (BMG) were the most prevalent lesions. The prevalence of potentially malignant disorders was lower than among the Brazilian population.The most prevalent lesion among the police officers was related to trauma. Patients dissatisfied with oral health had a higher risk of presenting OMLs. Key words:Mouth disease, mouth mucosa, military personnel, public health, oral pathology, oral leukoplakia.

Anterior knee pain is a common disorder in female athletes with an undefined cause. The relative prevalence of specific patellofemoral disorders associated with anterior knee pain in adolescent females remains undetermined. To determine the prevalence of specific patellofemoral disorders obtained using the differential diagnosis of anterior knee pain in adolescent female athletes during preparticipation screening. Descriptive epidemiology study. Preparticipation screening evaluations at a county public school district in Kentucky. A total of 419 unique middle and high school-aged female athletes. Participants were evaluated by physicians for anterior knee pain over 3 consecutive basketball seasons. Given the longitudinal nature of this study, some participants were tested longitudinally over multiple years. Over the course of 3 basketball seasons, 688 patient evaluations were performed. Of these, 183 (26.6%) were positive for anterior knee pain. A statistically significant difference was noted in the prevalence of anterior knee pain by school level, with 34.4% (n = 67) in high school-aged athletes versus 23.5% (n = 116) in middle school-aged athletes (P patellar tendinopathy, with 38 cases (9.7%) in high school-aged and 31 (3.1%) in middle school-aged athletes (P < .05). Anterior knee pain was present in 26.6% of the adolescent female athletes screened over 3 years. Symptoms of anterior knee pain likely persist after middle school-aged onset and reach peak prevalence during the high school years.

Overweight among young people in Sweden is increasing. The aim of the present study was to investigate the frequency of overweight and obesity based on body mass index (BMI) values among children and adolescents. Overweight was defined as a BMI value > or = 91st percentile and obesity as a BMI value > 98th percentile on an international reference BMI curve. The study population included boys and girls from four age groups: 9, 12, 15 and 18 y. The data consisted of self-reported measures of height and weight that were obtained from questionnaires used in a cross-sectional study in December 1997. A validation study was performed using a part of the study population. A total of 7011 (81.7%) participants completed the questionnaire. The correlation between self-reported estimations and objective measures of height and weight was high in the oldest age groups (0.88-0.98), but lower in the 9-y-old age groups (0.37-0.72). These self-reported estimations in the 9-y-olds were excluded from further analysis. It was found that 12.3%, 11.6% and 11.4% of the boys in the 12-, 15- and 18-y-old age groups and 6.8%, 5.5% and 4.8% of the girls in the same age groups were overweight and 7.9%, 8.9% and 7.3% of the boys and 5.1%, 4.2% and 3.9% of the girls were obese. The prevalence of overweight and obesity was found to be high in the study population and is a serious public health problem. The prevalence of obesity was significantly higher (p old boys living in rural areas than in city and town dwellers of the same age.

OBJECTIVE To assess the prevalence and correlates of insufficient physical activity in adolescents in Peru. METHODS We used a self-administered questionnaire developed from Global school-based Student Health Survey to collect information from secondary school students in North Lima and Callao in 2015. We carried out Poisson regression with robust variance using generalized linear models to estimate the crude and adjusted prevalence ratios (APR) with 95% confidence intervals (95%CI) of insufficient physical activity for its correlates. RESULTS We have found that 78% of the adolescents did not meet the global recommendation of the World Health Organization on physical activity in the last week before the survey. Female respondents (APR = 1.13, 95%CI 1.04-1.21), respondents who perceived themselves as overweight (APR = 1.10, 95%CI 1.03-1.18), and respondents who consumed insufficient vegetables and fruits [no vegetables (APR = 1.30, 95%CI 1.06-1.59), no fruits (APR = 1.15, 95%CI 1.00-1.31) as compared to those who consumed ≥ 2 servings every day in the last seven days] were more likely to report insufficient physical activity. Adolescents who worked after school (APR = 0.92, 95%CI 0.84-0.99), had physical education classes five times per week (APR = 0.94, 95%CI 0.88-0.99), and had parental supervision (APR = 0.92, 95%CI 0.87-0.98) were less likely to report insufficient physical activity. CONCLUSIONS Sex, work after school, perceived body weight, physical education class, parental support, and healthy dietary behaviors were associated with insufficient physical activity. Attempts to improve physical activity should look for ways to enhance leisure-time physical activity, parental support, physical education classes, healthy dietary behaviors, and normal body weight maintenance in adolescents with integrated efforts from the family and school.

This cross-sectional study included 1,743 school children of 12 to 17 years of age selected from ten public and private educational institutions, using a randomized and stratified sample of "conglomerados" (neighborhoods). In the selected schools, weight and height were measured. For the diagnosis of overweight and obesity, criteria from the WHO and CDC were used. For data analysis, descriptive and inferential statistics were performed. According to the WHO criteria, the prevalence of overweight was 33.7% (95% CI 31.5-36.0) and obesity was 14.4% (95% CI 12.8-16.1). According to CDC criteria, the prevalence of overweight was 26.5% (95% CI 24.4-28.6) and obesity was 13.9% (95% CI 12.3-15.6). The prevalence of overweight and obesity was significantly higher in males aged 12 and 13 years old and private educational institutions (poverweight and obesity. A high prevalence of overweight and obesity was found, predominantly in male students between 12 and 13 years and private educational institutions. It is necessary to initiate intervention measures that can contribute to the prevention of chronic diseases in adulthood, secondary to obesity in adolescence.

Full Text Available Background The World Health Organization (WHO has defined adolescence as the age group of 10-19 years. Adolescents in India comprise 19.3% of the total Indian population. Adolescence is a transition phase through which a child becomes an adult. It is characterized by rapid growth and development; physiologically, psychologically and socially. This period is marked by the onset of menarche. Menstruation is a natural, normal biological process experienced by all adolescent girls and women in reproductive age. Objectives To study the menstrual pattern and prevalence of dysmenorrhea among school going adolescent girls in a rural block of Haryana. Methods There were 18 government high and senior secondary schools in block Lakhanmajra. Out of these 5 were exclusively girls’ schools, 10 were co-ed schools and 3 were exclusively boys’ schools. All the 5 schools meant exclusively for girls were included in the study. All girls studying in 6th to 12th classes from these schools, after applying the exclusion criteria were included in the study. Results The mean age at menarche was 12.83±1.326 years. The inter-menstrual interval was 21 to 35 days in majority (80.1% of the adolescent girls and the duration of menstruation was more than 7 days in 9.4% of the girls. Majority of the girls (52.1% reported the duration of menstruation to be 2-3 days.

To investigate the prevalence and risk factors of dental erosion (DE) among a group of adolescents in Stockholm County. This cross sectional cohort study was conducted at three clinics of the Public Dental Service in Stockholm County. Fifteen and 17 year old adolescents (1335) who scheduled their regular dental health examination were asked to participate. After drop-outs a sample of 1071 individuals, 547 males and 524 females were enrolled in the study. Presence of erosive wear was diagnosed (yes/no) on marker teeth by trained dentists/dental hygienists and photographs were taken. The adolescents answered a questionnaire regarding oral symptoms, dietary and behavioural factors. Two calibrated specialist dentists performed evaluation of the photographs for severity of DE using a modified version of the Simplified Erosion Partial Recording System (SEPRS). DE was clinically diagnosed in 28.3% of 15 years old and 34.3% of 17 years old. Severe erosive wear (grade 3 and 4 according to SEPRS) was found in 18.3% of the adolescents based upon the intra-oral photographs. DE was more prevalent and severe among males than females. Clinically diagnosed erosive lesions correlated significantly with soft drink consumption (p < 0.001), the use of juice or sport drinks as a thirst quencher after exercise (p = 0.006) and tooth hypersensitivity when eating and drinking (p = 0.012). Furthermore, self-assessed gastric reflux was a factor strongly associated with DE (p < 0.001). The study indicated that DE was common among adolescents in Stockholm County and associated with both internal and external risk factors.

The goal was to determine the prevalence of high-risk HPV16 using saliva in a screening population in Detroit, Michigan. Real-time quantitative polymerase chain reaction was applied to detect HPV16 in saliva DNA from 349 screening subjects without head and neck cancer (HNC), 156 with HNC, and 19 controls. Cut points for human papilloma virus (HPV) positivity were >0 and >0.001 copy/cell. Proportions were compared between groups using exact χ(2) or Fisher exact tests (P 0, each group had an overall HPV prevalence of more than 5%, with a higher prevalence of 30.8% in the HNC patient group. At a cut point >0.001, the prevalence was lower: 0% in the control, 1.2% in the screening, and 16.7% in the HNC group. In the latter, for both cut points, HPV prevalence was different across sites (0, women in the screening group had a higher prevalence of HPV than did men (P = .010), and at >0.001, the prevalence was higher for men in the HNC group than for women (P = .035). In the screening group, at >0, only African Americans had a higher prevalence than Caucasian Americans (P = .025). In the screening group, a 6.9% and 1.2% screening rate was noted at cut points >0 and >0.001, respectively. The results provide data to inform public health considerations of the feasibility of saliva as a screening tool in at-risk populations with the long-term goal of prophylactic vaccination against oral HPV.

We investigated the prevalence of juvenile weapon carrying and psychosocial and personality-related risk factors for carrying different types of weapons in a nationally representative, population-based sample of Finnish adolescents. Specifically, we aimed to investigate psychopathic-like personality features as a risk factor for weapon carrying. The participants were 15-16-year-old adolescents from the Finnish self-report delinquency study (n = 4855). Four different groups were formed based on self-reported weapon carrying: no weapon carrying, carrying knife, gun or other weapon. The associations between psychosocial factors, psychopathic-like features and weapon carrying were examined with multinomial logistic regression analysis. 9% of the participants had carried a weapon in the past 12 months. Adolescents with a history of delinquency, victimization and antisocial friends were more likely to carry weapons in general; however, delinquency and victimization were most strongly related to gun carrying, while perceived peer delinquency (antisocial friends) was most strongly related to carrying a knife. Better academic performance was associated with a reduced likelihood of carrying a gun and knife, while feeling secure correlated with a reduced likelihood of gun carrying only. Psychopathic-like features were related to a higher likelihood of weapon carrying, even after adjusting for other risk factors. The findings of the study suggest that adolescents carrying a weapon have a large cluster of problems in their lives, which may vary based on the type of weapon carried. Furthermore, psychopathic-like features strongly relate to a higher risk of carrying a weapon.

2013-01-01

Purpose The purpose of this study was to document the prevalence of harassment on the basis of weight, race/ethnicity, and socioeconomic status, as well as sexual harassment, among a diverse population of adolescents. Specifically, this study examined rates of each type of harassment reported across groups within the corresponding sociodemographic category (e.g., racial/ethnic category differences in prevalence of racial harassment), and also explored patterns of “cross-harassment” (i.e., differences in prevalence of each harassment type across all other sociodemographic characteristics). Methods Data from EAT 2010 (Eating and Activity in Teens) were used for the current study. The sample was comprised of 2,793 adolescents (53% female; 81% non-white). Regression analyses were conducted to yield prevalence estimates of each type of harassment in each demographic and BMI category. Results Weight- and race-based harassment (35.3% and 35.2%, respectively) were most prevalent, followed by sexual harassment (25.0%) and SES-based harassment (16.1%). Overweight and obese adolescents reported disproportionately higher rates of all forms of harassment than did normal-weight and underweight adolescents. In addition, Asian and mixed-/other-race adolescents were more vulnerable to harassment overall as compared to those from other racial/ethnic groups. Conclusions Harassment experiences are prevalent among adolescent boys and girls. Differential rates of each type of harassment are reported across groups within the corresponding sociodemographic category, but a pattern of “cross-harassment” also is evident, such that differences in prevalence of each type of harassment emerge across a variety of sociodemographic characteristics. Adolescents from various intersecting sociodemographic and weight-status groups are particularly vulnerable to certain types of harassment. PMID:23566562

The objectives were to describe the frequency of clinical presentation at the onset of type 1 diabetes mellitus (T1DM) and to estimate the prevalence of T1DM among children and adolescents in the AL-Baha region, Saudi Arabia, aiming for early diagnosis of T1DM. The clinical and laboratory data of 471 children and adolescents who presented with T1DM and received medical care at an AL-Baha diabetic center during the period from 2007 to 2016 were retrospectively analyzed based on the records. The prevalence of T1DM in the AL-Baha region was 355 per 100,000 population in participants aged from 0 to 19 years. T1DM was more common among girls than boys (57.5% vs. 42.5%, respectively; p=0.3), and the female/male ratio was 1.36 in favor of girls. Hyperglycemic symptoms were the most frequent symptoms at presentation [59.2% vs. 40.8% with diabetic ketoacidosis (DKA)], and 37% of them presented with loss of weight. Most of the ketoacidosis was mild to moderate (80.2%), while only 19.8% of children had the severe type and DKA was more common (55.2%) among females. The mean age at diagnosis of T1DM was 8.2±3.5 years for all patients, and 8.3±3.9 and 8.9±3.6 years for boys and girls, respectively (p=0.06). Hyperglycemic symptoms were more common in spring (15.9%). The prevalence of type 1 diabetes in the AL-Baha region was 355 per 100,000 population, which is one of the highest reported prevalences in this age group. Hyperglycemic symptoms were the most encountered symptoms at the onset of the presentation of T1DM and this may help in early detection of diabetic symptoms by patients and physicians to avoid the more severe types of presentation.

Full Text Available Abstract Objective: This study investigated the presence of musculoskeletal symptoms in high school adolescents from public schools and its association with electronic device use. Methods: The sample consisted of 961 boys and girls aged 14–19 years who answered a questionnaire regarding the use of computers and electronic games, and questions about pain symptoms and physical activity. Furthermore, anthropometric assessments of all volunteers were performed. The chi-squared test and a multiple logistic regression model were used for the inferential analysis. Results: The presence of musculoskeletal pain symptoms was reported by 65.1% of the adolescents, being more prevalent in the thoracolumbar spine (46.9%, followed by pain in the upper limbs, representing 20% of complaints. The mean time of use for computers and electronic games was 1.720 and 583 minutes per week, respectively. The excessive use of electronic devices was demonstrated to be a risk factor for cervical and lumbar pain. Female gender was associated with the presence of pain in different body parts. Presence of a paid job was associated with cervical pain. Conclusion: A high prevalence of musculoskeletal pain in adolescents, as well as an increased amount of time using digital devices was observed. However, it was only possible to observe an association between the increased use of these devices and the presence of cervical and low back pain.

Data were collected using a stratified, multistage and probability sample. Prevalence, odds ratios and 95% confidence intervals for LEs and PTSD (assessed with DSM-IV criteria) were obtained. The percentage of adolescents reporting at least one traumatic event in their lifetimes was 68.9%, with differences by sex. Prevalence for PTSD were 1.8% (2.4% females and 1.2% males), and sexual-related traumas were the LEs most associated with PTSD [OR=3.9 (CI95%=1.8-8.2)], adjusted by sex, education and age. Exposure to traumatic life events is not uncommon among Mexico City adolescents. Effort should be made to reduce child and adolescent sexual abuse, a very traumatic event highly associated with PTSD.

A cross-sectional study design was applied amongst a random sample (n = 10158) of Chinese adolescents. Self-completed questionnaires, including demographic characteristics, Internet use situation, Youth Internet Addiction Test, Youth Social Support Rating Scale and Zung Self-rating Depression Scale were utilized to examine the study objectives. Among the study population, the prevalence rate of Internet addiction was 10.4%, with 1038 (10.2%) moderately and 21 (0.2%) severely addicted to the Internet. Results from the multivariate logistic regression analyses suggested that a variety of related factors have significant effects on Internet addiction (parental control, per capita annual household income, academic performance, the access to Internet, online activities). The correlation coefficients showed that Internet addiction was negatively correlated with social support and positively associated with depression. Social support had a significant negative predictive effect on Internet addiction. The mediating effect of depression between social support and Internet addiction was remarkable.

It is important to update weight-for-length/height growth curves in China and re-examine their performance in screening malnutrition. To develop weight-for-length/height growth curves for Chinese children and adolescents. A total of 94 302 children aged 0-19 years with complete sex, age, weight and length/height data were obtained from two cross-sectional large-scaled national surveys in China. Weight-for-length/height growth curves were constructed using the LMS method before and after average spermarcheal/menarcheal ages, respectively. Screening performance in prevalence estimates of wasting, overweight and obesity was compared between weight-for-height and body mass index (BMI) criteria based on a test population of 21 416 children aged 3-18. The smoothed weight-for-length percentiles and Z-scores growth curves with length 46-110 cm for both sexes and weight-for-height with height 70-180 cm for boys and 70-170 cm for girls were established. The weight-for-height and BMI-for-age had strong correlation in screening wasting, overweight and obesity in each age-sex group. There was no striking difference in prevalence estimates of wasting, overweight and obesity between two indicators except for obesity prevalence at ages 6-11. This set of smoothed weight-for-length/height growth curves may be useful in assessing nutritional status from infants to post-pubertal adolescents.

To determine the prevalence of amblyopia and its determinants in a population-based study in Mashhad County, Iran. This cross-sectional, population-based study was conducted on the population of Mashhad County aged >1 year using randomized stratified cluster sampling. Examinations were performed after selection of the participants and their free transportation to the sampling site. The examinations included the measurement of uncorrected and corrected visual acuity, cycloplegic and non-cycloplegic refraction, cover testing, slit-lamp biomicroscopy, and ophthalmoscopy. In this study, amblyopia was defined as best corrected visual acuity (BCVA) of 20/30 or less or 2-line interocular optotype acuity differences with no pathology. After considering the exclusion criteria, the data of 2739 individuals, 65.6% of whom were women, were analyzed. The mean age of the participants was 29.5±17.5 years. The prevalence of amblyopia was 4.6% (95% CI: 3.77%-5.43%) in the total population. The lowest prevalence was 2.24% in the age group 5-15 years (95% CI: 0.99%-3.48%) and the highest prevalence was 7.14% in the age group 55-65 years (95% CI: 2.64%-11.56%). Anisometropic amblyopia was observed in 45.24% of the amblyopic participants. Isometropic, mixed (strabismic/anisometropic), and strabismic amblyopia were other common causes of amblyopia, with a prevalence of 24.6%, 16.67%, and 13.49% in amblyopic patients, respectively. The odds ratio (OR) of having amblyopia for each 1-year increase in age was 1.02 (95% CI: 1.01-1.03). Amblyopia was less common in people with better socioeconomic status. This study showed the prevalence of amblyopia in all age groups in a population-based study for the first time. The findings of this study regarding the relatively high prevalence of amblyopia in the older population and its lower prevalence in young people indicate attention to amblyopia in recent years.

The aims of the study were to determine the prevalence of ADHD in a population of high school students and to explore the factors associated with this disorder. This was a cross-sectional study that had included 447 high school students. The diagnosis of ADHD was made by the Adult ADHD Self-Report Scale translated in Arabic language. The sociodemographic and clinical characteristics were evaluated by a preestablished questionnaire. The self-esteem was assessed by the Rosenberg Self-Esteem Scale. The prevalence of ADHD was 18.1%. The logistic regression analysis showed an association between the diagnosis of ADHD and the bad relationships with parents (odds ratio [OR] = 16.43; p antecedents (OR = 12.16; p antecedents (OR = 3.16; p = .009). The prevalence of ADHD in this study was one of the highest prevalence reported. The factors associated with ADHD may have diagnostic and therapeutic implications.

In China, epidemiologic information on celiac disease autoimmunity is scarce and fragmented. We investigated the prevalence of celiac disease autoimmunity in the general Chinese population. In a cross-sectional prospective study, 19,778 undiagnosed Chinese adolescents and young adults (age, 16-25 y) were recruited from consecutive new students who underwent routine physical examinations at 2 universities in Jiangxi, China, from September 2010 through October 2013; the students were from 27 geographic regions in China. All subjects were tested for serum IgG, IgG against deamidated gliadin peptides (IgG anti-DGP), and IgA anti-tissue transglutaminase antibodies (IgA anti-tTG). We also analyzed HLA genotypes in subgroups of participants with different results from tests for serum markers of celiac disease. A total of 434 students (2.19%) tested positive for serum markers for celiac disease (95% confidence interval [CI], 1.99%-2.41%), 0.36% of the students tested positive for anti-tTG IgA (95% CI, 0.28%-0.46%), and 1.88% tested positive for anti-DGP IgG (95% CI, 1.70%-2.09%). The prevalence of celiac disease autoimmunity (positive results in assays for anti-tTG IgA and anti-DGP-IgG) was 0.06% (95% CI, 0.03%-0.10%). Celiac disease autoimmunity was associated with the consumption of wheat and female sex. The prevalence in the Shandong province in north China, where wheat is a staple in the diet, was 0.76% (95% CI, 0.21%-1.95%). The frequencies of the HLA-DQ2/-DQ8 genotypes associated with celiac disease were higher in subjects with celiac disease autoimmunity, based on detection of both serum markers, than in subjects with positive results from a single test (P celiac disease. The prevalence of celiac disease autoimmunity in the Shandong province in north China, where wheat is a staple in the diet, was 0.76%. Copyright © 2017 AGA Institute. Published by Elsevier Inc.

Previous studies assessing vitamin D status in adolescents with eating disorders showed inconsistent results. The aim of the current study was to assess vitamin D status in a large cohort of adolescent inpatients with eating disorders and its relation to bone mineral density (BMD) and depression. 25-Hydroxyvitamin D (25OHD), calcium, phosphorus, and alkaline phosphatase levels as well as BMD and depression were assessed on admission in 87 inpatients (aged 16 ± 2 years, females = 81) with eating disorders [anorexia nervosa (AN) = 64; bulimia nervosa (BN) = 5; eating disorders not otherwise specified-binge/purge type (EDNOS-B/P) = 18]. Mean 25OHD levels were 24.1 ± 7.5 ng/ml (25.0 ± 7.6, 25.4 ± 9.9, and 22.0 ± 9.9 ng/ml in patients with AB, BN, and EDNOS-B/P, respectively). Vitamin D deficiency (32 ng/ml, considered optimal by some experts. No associations were found between 25OHD levels and BMD or comorbid depression. 25OHD levels during winter were significantly lower than summer levels (p EDNOS-B/P type was low (-1.5 ± 1.1) and correlated with body mass index standard deviation score (p = .03). Adolescents with eating disorders show a high prevalence of vitamin D deficiency and insufficiency. Given the risk of osteoporosis in this population, 25OHD levels found in this group may not offer optimal bone protection. Vitamin D levels should be routinely checked and supplementation should be administered as required. © 2014 Wiley Periodicals, Inc.

To examine the prevalence of bullying victimization among adolescents referred for urgent psychiatric consultation, to study the association between bullying victimization and suicidality, and to examine the relation between different types of bullying and suicidality. A retrospective chart review was conducted for all adolescents referred to a hospital-based urgent consultation clinic. Our study sample consisted of adolescents with a history of bullying victimization. The Research Ethics Board of Queen's University provided approval. Data analysis was conducted using SPSS (IBM SPSS Inc, Armonk, NY). Chi-square tests were used for sex, suicidal ideation, history of physical and sexual abuse, and time and type of bullying, and an independent sample t test was used for age. The prevalence of bullying victimization was 48.5% (182 of 375). There was a significant association between being bullied and suicidal ideation (P = 0.01), and between sex and suicidal ideation (P ≤ 0.001). Victims of cyberbullying reported more suicidal ideation than those who experienced physical or verbal bullying (P = 0.04). Bullying victimization, especially cyberbullying, is associated with increased risk of suicidal ideation among adolescents referred for psychiatric risk assessment. The detailed history of the type and duration of bullying experienced by the victims should be considered when conducting a psychiatric risk assessment.

To determine the prevalence and correlates for current cigarette smoking. Secondary analysis of the East Timor-Leste Global Youth Tobacco Survey conducted in 2006. Public and private schools registered with the Ministry of Education. A two-stage cluster sample of 1790 students in Grades 7 to 9. Schools were selected with probability proportional to enrolment size, and classes were randomly selected in each school. All students in selected classes were eligible to participate in the survey. The school and student response rates were 96.0% and 84.5%, respectively. Prevalence of current cigarette smoking. Out of 1790 adolescents, 52.1% were of ages less than 15 years, 51.8% were males, 42.8% reported having some pocket money in a month, and 72.7% had at least a parent who was a smoker. Prevalence of current cigarette smoking was 40.3%. Current smokers also reported having bought cigarettes from peddlers (32.4%), someone bought for them (16.7%), got from someone older (13.7%), borrowed (13.3%), and stole (3.4%). Males were more likely to be smokers than females (59.0% versus 19.3%). Factors positively associated with current smoking were: parental smoking; closest friend smoking; amount of pocket money; and exposure to anti-tobacco messages. East Timor has one of the highest prevalence of cigarette smoking among adolescents. The fact that exposure to anti-tobacco messages was associated with being a smoker may be evidence suggesting that anti-tobacco messages, especially from tobacco-related industry, may have unintended consequences.

To evaluate the correlation between constipation and lower urinary tract dysfunction (LUTD) and nocturnal enuresis in a population-based study. This is a cross-sectional study. The criteria for inclusion were children and adolescents of between 5 and 17 years and who agreed to sign the informed consent form. The study excluded students with neurological problems or who had documented abnormalities of the urinary tract. To identify the presence and severity of LUTD, we used the Voiding Dysfunction Symptom Score (DVSS). To evaluate the presence of constipation, Rome III questionnaire was used. We interviewed 829 children and adolescents, of which 416 (50.18%) were male. The mean (SD) age was 9.1 (±2.9) years. The overall prevalence of LUTD was 9.1%, predominantly in girls (15 versus 3.1%, p  urinary symptoms that are independent predictors of the presence of constipation. The presence of infrequent urination ( p  = 0.004) and holding maneuvers ( p  urinary symptoms, infrequent voiding and holding maneuvers are independent factors of urinary expressions in constipated children. Children with more severe constipation have more prominent urinary symptoms. The presence of enuresis was not associated with constipation.

Background The trend towards increased psychotropic drug prescribing in children and adolescents is well recognised in North America and continental Europe. However, it is unclear to what extent these studies are applicable to clinical practice in the United Kingdom (UK). This study was conducted to estimate the prevalence of psychotropic drug prescribing in children and adolescents aged <19 years in general practice in the UK from January 1992 to December 2001. Methods Data were obtained from the General Practice Research Database (GPRD). Annual age- and sex-specific prevalence of psychotropic drug prescribing was calculated. Results A total of 143,079 prescriptions were issued to 34,398 study subjects. Stimulant prescriptions rose significantly from 0.03 per 1,000 (95% confidence interval 0.02-0.04) in 1992 to 2.9 per 1,000 (2.52-3.32) in 2001; a 96-fold increase. Methylphenidate accounted for the majority of stimulant prescriptions; 2.4% (349/14,370) of stimulant prescriptions were prescribed to children aged <6 years. Increased prescribing was also noted for antidepressants (1.6-fold), hypnotics/anxiolytics (1.3-fold), antipsychotics (1.3-fold) and anticonvulsants (1.3-fold), whilst the prevalence of clonidine and lithium prescribing remained fairly stable throughout the study period. The use of antidepressant, hypnotic/anxiolytic and anticonvulsant increased with increasing age. A high proportion of boys received stimulants, whereas antidepressants and hypnotics/anxiolytics were more likely prescribed to girls. Conclusion There is an increased trend of psychotropic drug use in children and adolescents in the UK practice. Since most psychotropic drugs are not licensed for use in children at this time, research is needed to investigate the efficacy and long-term safety in this population

This study investigates the prevalence and subtypes of conduct disorder (CD) and behavioral problems among youth in two communities characterized by prolonged parent-child separation upon immigration. CD and problem behaviors were assessed in 252 Caribbean-Canadian and Filipino-Canadian adolescents (12-19-year-old) using the DISC-C, the YSR and the CBCL cross-informant construct. Adolescents reported less problem behaviors than their host country peers, despite immigrant background or parent-child separation. The high adolescent-onset CD rate supports the hypothesis that psychosocial stressors play a role in the emergence of the disorder. Specifically, high levels of perceived racism and low collective self-esteem predicted problem behaviors in these youngsters.

This study aimed to determine the trends in prevalence of childhood overweight and malnutrition in a large Chinese ethnic minority population from 1991 to 2010. In the Chinese National Survey on Students’ Constitution and Health from 1991 to 2010, multistage stratified sampling was conducted in the series of cross-sectional studies. Participants were 7–18-year-old students randomly selected by sex and region, and included Han and 26 ethnic minorities. During the survey period, the overall prevalence of overweight increased from 5.8% to 13.5%, and malnutrition trend increased from 3.6% to 4.1% in ethnic minority children and adolescents. Moreover, Korean and Mongol children were more likely than Han children to be obese (Korean: RR = 1.52; 95% CI: 1.48–1.56; Mongol: RR = 1.24; 95% CI: 1.20–1.28). Among these minorities, the Dongxiang and Li children were more likely to be malnourished (Li: RR = 1.47; 95% CI: 1.37–1.57; Dongxiang: RR = 1.45; 95% CI: 1.34–1.58). Shui, Khalkhas, Lisu, and Monguor children were less likely to be overweight and malnourished compared with the Hans. The prevalence of overweight among ethnicities increased yearly while that for malnutrition has fluctuated over the past few decades. PMID:27881845
