    In Mexico, about one third of school-age population is overweight or obese and the diet is one of the main determinants. The purpose of this study was to identify the dietary patterns of Mexican school-age children and to determine their association with the risk of overweight/obesity. This study included 8252 school-age children who participated in the 2006 National Health and Nutrition Survey (ENSANUT-2006). Dietary data were collected using a 7-day Food Frequency Questionnaire (FFQ). Foods were classified into 25 groups and dietary patterns were defined by cluster analysis. Body Mass Index and prevalence of overweight/obesity were calculated. Logistic regression models were used to evaluate the association between dietary patterns and overweight/obesity. Five dietary patterns were identified: Rural dietary pattern (high intake of tortilla and legumes), sweet cereal and corn dishes pattern (high intake of sugary cereals, tortilla, and maize products); diverse pattern (intake of several food groups); western pattern (high intake of sweetened beverages, fried snacks, industrial snack cakes, and sugary cereals), and whole milk and sweet pattern (high intake of whole milk and sweets). We found that children with sweet cereal and corn dishes and western dietary patterns showed an association with overweight and obesity (prevalence ratio 1.29 and 1.35, respectively, using as reference the rural dietary pattern). Patterns characterized by high intakes of sugary cereals, sweetened beverages, industrial snack, cakes, whole milk, and sweets were associated with a higher risk of overweight/obesity among in Mexican school-age children.

    Full Text Available OBJECTIVE: To estimate energy and nutrient intake and adequacy in preschool and school age Mexican children, using the National Nutrition Survey 1999 (NNS-1999. MATERIAL AND METHODS: Twenty four-h dietary recalls from pre-school (n=1 309 and school (n=2 611 children obtained from a representative sub-sample of the NNS-1999 were analyzed. Intakes and adequacies were estimated and compared across four regions, socio-economic strata, and between urban and rural areas, and indigenous vs. non-indigenous children. RESULTS: Median energy intake in pre-school children was 949 kcal and in school children 1 377 kcal, with adequacies 150% in both age groups. The North and Mexico City regions had the highest fat intake and the lowest fiber intake. Children in the South region, indigenous children, and those in the lowest socio-economic stratum had higher fiber and carbohydrate intakes and the lowest fat intake. These children also showed the highest risks of inadequacies for vitamin A, vitamin C, folate, iron, zinc and calcium. CONCLUSIONS: Mexico is experiencing a nutrition transition with internal inequalities across regions and socio-economic strata. Food policy must account for these differences in order to optimize resources directed at social programs.

    Dietary and lifestyle changes in Mexico have been linked to an increase in chronic diseases such as obesity and cardiovascular disease. Important dietary changes such as an increase in the consumption of energy-dense foods (high in oils, animal or processed fats, and sugars) have been recently reported. The objective of this study was to identify how key dietary energy sources correlated with other indexes of cardiovascular disease in a Mexican school-age population. From 2004 to 2006, a convenience sample (n=228) of 9- to 13-year-olds, 48.2% girls and 51.8% boys, from three public urban schools were included. Anthropometric, blood pressure, and dietary assessment (two multiple pass 24-hour recalls) were done. More than half of children did not meet the fruit and vegetable recommended intake. High-fat dairy foods (14% of total energy intake), refined carbohydrates (13.5%), red/processed meat (8.5%), added sugars/desserts (7%), corn tortilla (6.5%), and soft drinks/sweetened beverages (5%) were the highest dietary energy sources consumed. In a subgroup of children (n=185), a fasting blood sample was collected for biochemical analysis. A positive association was observed between glucose and diastolic blood pressure with the intake of soft drinks/sweetened beverages, insulin concentrations and the intake of white bread, and triglyceride concentrations with the intake of added fats. Unhealthful dietary energy sources are frequently consumed by these children. Culturally competent nutrition counseling should be offered to Mexican-American children and their families with a significant risk of cardiovascular disease. Efforts should be made to design and implement nutrition education and health promotion strategies in schools. Copyright 2010 American Dietetic Association. Published by Elsevier Inc.

The highest prevalence figures were found in Mexico City (26.6% and the North region (25.6%. When adjusting by region, rural or urban area, sex, maternal schooling, socioeconomic status, indigenous ethnicity and age, the highest prevalences of overweight and obesity were found among girls. The risks of overweight and obesity were positively associated with maternal schooling, children's age and socioeconomic status. CONCLUSIONS: Overweight and obesity are prevalent health problems in Mexican school-age children, particularly among girls, and positively associated with socioeconomic status, age, and maternal schooling. This is a major public health problem requiring preventive interventions to avoid future health consequences.

    To establish the school eating habits of Mexican children, who are prone to obesity and later to high rates of adult chronic diseases. Questionnaires for students and parents with staff questionnaires and interviews. Randomly sampled schools in a socio-economically representative district of Mexico City. Subjects were 1504 adolescents aged 10-19 years attending schools in Mexico City, 27 teachers and seven headmasters, sampled from both public and private schools and from the full range of socio-economic groups. Foods brought from home were of a higher nutritional quality than those purchased at school, where purchases were dominated by crisps, soft drinks and other items with high energy density. Girls were more inclined to purchase inappropriately; those from poorer homes purchased less. Private-school students irrespective of socio-economic grade brought more food from home and purchased more expensive food at school. School policies allowed food and drink vendors to market any products within the schools, which benefited financially from these activities. Current school food policies are conducive to amplifying the current epidemic of obesity and related adult chronic diseases, and need to change.

    Full Text Available Aim: To present the results of a community initiative focused on strengthening physical activity and the consumption of fruits, vegetables and natural water while discouraging the use of highly energetic food and sugary drinks in public schools of Morelos. Methods: A quasi-experimental study with an educational initiative focused on the school community of two primary schools and two junior high schools. Pre- and-post initiative measurements were made. The study took place in the municipality of Yautepec, Morelos, Mexico, in a rural area and an urban area, from August 2010 to July 2011.   Results: Water consumption among school-aged children increased from 15.1% to 20.1% and soda consumption decreased from 21.4% to 13.2%. A slight increase in the consumption of fruits and vegetables was also measured (oranges, jicamas, bananas, tomatoes, prickly pear pads, lettuces, that are accessible in the region. It was found that the supply of fresh food is limited and that high energy density foods have an oversupply in both study areas. Physical activity increased with actions such as football and dancing, in accordance with the baseline measurement. No changes were observed in the nutritional condition of school-aged children (n=150; 13.3% with overweight and 7.3% with emaciation, or in adults who presented a body mass index higher than normal, 60.2% to 88.4%. Conclusion: In addition to educational activities, schools need to implement strategies to improve the access and availability of fresh foods while limiting the access of high energy-density foods.

    Mexico has the highest and most alarming rates of childhood obesity worldwide. A study conducted in the State of Mexico revealed that one of every three children presents overweight or obesity. The objective of this paper is to provide a step-by-step description of the design and implementation of an educational intervention to promote healthy eating and physical activity called "Healthy Recess". The educational intervention was designed using the six stages of the Health Communication Process. This methodological model allowed identifying the needs of school-age children on information and participation in activities. In order to improve the strategy, adjustments were made to the print and audiovisual materials as well as to assessment tools. Typography was modified as well as the color of the images in student's workbook and facilitator's; special effects of the videos were increased; the narration of the radio spots was improved and common words and phrases were included. The Health Communication Process is an effective tool for program planners to design interventions aimed at managing prevalent health problems such as overweight and obesity in school-age children.

    To estimate the mean age of sexual intercourse debut (SID) and associated family and individual factors in 14-19-year-olds of both sexes in the 32 states of Mexico in 2007. A cross-sectional study was conducted of a representative sample of 9,893 students aged between 14 and 19 years old. The data were collected through a self-administered, anonymous and voluntary questionnaire. Logistic regression models were used to estimate odds ratios (OR) with 95% confidence intervals (95%CI) by category: no SID, SID at 10-15 years and SID at 16-19 years. The national mean age of SID was 16 years, being 15 years for boys (95%CI: 15.88-16.11) and 16 years for girls (95%CI: 15.26-15.42). Factors associated with SID in boys were disadvantaged socioeconomic level (OR=0.66; 95%CI: 0.46-0.94), living with parents (OR=0.65; 95%CI: 0.56-0.75), less offensive communication between parents and boys/girls (OR=0.66; 95%CI: 0.57-0.77), and high social self-esteem (OR=1.68; 95%CI: 1.35-1.77). Factors associated with SID in girls were traditional gender beliefs (OR=0.49; 95%CI: 0.32-0.74), high depressive symptoms (OR=1.88; 95%CI: 1.19-2.99), and high family self-esteem (OR= 0.50; 95%CI: 0.38-0.65). In Mexico, SID occurred early in boys. In addition, the findings of this study show that in Mexico, the age of SID and associated factors differ in boys and girls. The age of SID is strongly influenced by gender and cultural beliefs. Copyright © 2015 SESPAS. Published by Elsevier Espana. All rights reserved.

    Metabolic syndrome (MetS) is a disorder that includes a cluster of several risk factors for the development of type 2 diabetes and cardiovascular disease. The R230C variant of the ABCA1 gene has been associated with low HDL-cholesterol in several studies, but its association with MetS in children remains to be determined. The aim of this study was to analyze the association of the R230C variant with MetS and other metabolic traits in school-aged Mexican children. The study was performed in seven urban primary schools in the State of Mexico. Four hundred thirty-two Mexican school-age children 6-13 years old were recruited. MetS was identified using the International Diabetes Federation definition. The R230C variant of the ABCA1 gene was genotyped to seek associations with MetS and other metabolic traits. The prevalence of MetS was 29% in children aged 10-13 years. The R230C variant was not associated with MetS (OR = 1.65; p = 0.139). Furthermore, in the whole population, the R230C variant was associated with low HDL-cholesterol levels (β coefficient = -3.28, p children. Copyright © 2015 IMSS. Published by Elsevier Inc.

    Childhood obesity is a serious public health problem in Mexico. Adult gut microbiota composition has been linked to obesity, but few studies have addressed the role of gut microbiota in childhood obesity. The aim of this study is to compare gut microbiota composition in obese and normal-weight children and to associate gut microbiota profiles with amino acid serum levels and obesity-related metabolic traits. Microbial taxa relative abundance was determined by 16S rRNA sequencing in 67 normal-weight and 71 obese children aged 6-12 years. Serum amino acid levels were measured by mass spectrometry. Associations between microbiota composition, metabolic parameters and amino acid serum levels were tested. No significant differences in phyla abundances or Firmicutes/Bacteroidetes ratios were observed between normal-weight and obese children. However, Bacteroides eggerthii abundance was significantly higher in obese children and correlated positively with body fat percentage and negatively with insoluble fibre intake. Additionally, Bacteroides plebeius and unclassified Christensenellaceae abundances were significantly higher in normal-weight children. Abundance of both these species correlated negatively with phenylalanine serum levels, a metabolite also found to be associated with obesity in Mexican children. The study identified bacterial species associated with obesity, metabolic complications and amino acid serum levels in Mexican children. © 2017 World Obesity Federation.

    The objective of our study was to evaluate the association between consumption of food during the journey from home to school and back, with overweight and obesity, in a nationwide representative sample of school children. We assessed consumption outside the home in 9537 children, with information on availability and consumption of selected groups of food and beverages. Height, weight, total energy consumption, and sociodemographic variables were also obtained. We developed logistic regression models, and tested interactions with sociodemographic variables. The results of our study show that the prevalence of overweight and obesity was positively associated with dairy consumption in girls (OR:1.70; p = 0.01), as well as fried snacks consumption in school children living in Mexico City (OR: 1.68; p = 0.06). Consumption of fruits and vegetables in medium and high socioeconomic levels was negatively associated with the prevalence of overweight and obesity (OR: 0.54; p = 0.01 and 0.59; p = 0.07, respectively). We concluded that children during their stay away from home have a high availability of energy dense foods, which can influence their consumption and contribute to the development of overweight and obesity, so it is important to investigate this association in prospective studies.

    Full Text Available The present study deals with initial formation of concept of decimal system in second year of education at primary school in Mexico (City of Puebla. Our research is based on Activity Theory conception of teaching-learning process and of gradual introduction of scientific concepts in school age. The method has been designed and worked out with the help of actions in which logic, symbolic, spatial and mathematical aspects were implemented. All actions were introduced within divided activity of children in group guided by adult. A pretest-posttest design was used with an experimental group of Mexican school children. The results showed that children have developed the significant skills necessary for understanding the concept of decimal number system. They were also able to apply this concept for new kind if activity al the end of school year. Such new activity was solving of mathematic problems, which was not included in official school program. We consider that proposed method can be an approximation for solution of common difficulties which arise at primary school concerning teaching of mathematics.

  13. PREFACE: VI Mexican School on Gravitation and Mathematical Physics

    Alcubierre, Miguel; Cervantes-Cota, Jorge L.; Montesinos, Merced

    2005-01-01

    The Mexican School on Gravitation and Mathematical Physics, sponsored by the Mexican Physical Society, started in the early 1990s. The aim of the school is to consider different topics at the frontiers of current research on gravitation, field theory and mathematical physics. It is held every two years and a different theme is chosen on each occasion. The school, which is oriented towards advanced graduate students and non-expert researchers, has been gaining reputation because of the quality of the lectures given by leaders in each field. On previous occasions, the subjects covered have been Supergravity and Mathematical Physics, Branes, Black Holes, Early Universe and Observational Cosmology, and the speakers have included A. Ashtekar, A. Balachandran, J. Barrow, B. Carter, P. Chrusciel, G. Gibbons, M. Heusler, W. Israel, F. Müller-Hoisen, R. Kallosh, A. Linde, Y. Neeman, R. Myers, A. Peet, L. Randall, C. Rovelli, L. Smolin, R. Sorkin, P. Van Niewenhuizen, R. Wald, among other top ranked physicists. Let us now turn our attention to the current edition of the school. The two great pillars of twentieth century physics are quantum mechanics and the general theory of relativity (GR) and, in spite of their great independent successes, it has been enormously difficult to combine them into a single theoretical framework. It seems that the nonlinearities of GR and its attractive nature pose severe problems to understand its possible quantum nature, e.g. renormalization issues. In order to solve this and other quantization problems, as well as to try to unify gravity with the other quantum fields (electromagnetic, weak, and strong fields), in the past decades several different approaches to quantum gravity have been developed. In view of the fundamental importance of such topics today, the theme Approaches to Quantum Gravity was chosen for the VI Mexican School on Gravitation and Mathematical Physics. We considered that subjects like loop quantum gravity (quantum

    Full Text Available OBJECTIVE: To estimate energy and nutrient intake and adequacy in preschool and school age Mexican children, using the National Nutrition Survey 1999 (NNS-1999. MATERIAL AND METHODS: Twenty four-h dietary recalls from pre-school (n=1 309 and school (n=2 611 children obtained from a representative sub-sample of the NNS-1999 were analyzed. Intakes and adequacies were estimated and compared across four regions, socio-economic strata, and between urban and rural areas, and indigenous vs. non-indigenous children. RESULTS: Median energy intake in pre-school children was 949 kcal and in school children 1 377 kcal, with adequacies 150% in both age groups. The North and Mexico City regions had the highest fat intake and the lowest fiber intake. Children in the South region, indigenous children, and those in the lowest socio-economic stratum had higher fiber and carbohydrate intakes and the lowest fat intake. These children also showed the highest risks of inadequacies for vitamin A, vitamin C, folate, iron, zinc and calcium. CONCLUSIONS: Mexico is experiencing a nutrition transition with internal inequalities across regions and socio-economic strata. Food policy must account for these differences in order to optimize resources directed at social programs.OBJETIVO: Estimar el consumo de energía y nutrimentos y su adecuación en niños prescolares y escolares mexicanos, usando datos de la Encuesta Nacional de Nutrición 1999 (ENN-1999.

    Full Text Available The aim of this study was to analyze the relationships between three development contexts -family, school and community-, and school violence, examining psychological distress and social selfesteem from a gender perspective in Mexican adolescents. To test these relationships, 1,285 Mexican students between 12 and 18 years of age in secondary (n = 634 and high school (n = 651 were recruited. To analyze these relationships, Structural Equation Modeling With EQS was used. Results showed that familial context is directly related to school violence, and that school and community context is indirectly related to school violence through social self-esteem and psychological distress. Finally, results and their possible implications regarding gender are discussed.

    2012-01-01

    This study examined ethnic identity, perceptions of discrimination, and academic attitudes and performance of primarily first- and second-generation Mexican immigrant children living in a predominantly White community (N=204, 19 schools, mean age=9years). The study also examined schools' promotion of multiculturalism and teachers' attitudes about the value of diversity in predicting immigrant youth's attitudes and experiences. Results indicated that Latino immigrant children in this White community held positive and important ethnic identities and perceived low overall rates of discrimination. As expected, however, school and teacher characteristics were important in predicting children's perceptions of discrimination and ethnic identity, and moderated whether perceptions of discrimination and ethnic identity were related to attitudes about school and academic performance. © 2012 The Authors.

    To obtain the prevalence of disordered eating (DE) among student female adolescents from public high schools in 17 urban settings in the Mexican Republic, across age, setting and region. The sample comprised 4358 female students 15 to 19 years of age. DE was evaluated with a validated and standardized questionnaire for Mexican adolescents with 2 cutoff points: moderate-DE and high-DE. The total prevalence of moderate-DE was 14.2% and 6.8% for high-DE. Significant statistical differences were found only for high-DE across settings, were the Estado de Mexico reached the highest score (12.1%) and Aguascalientes the lowest (2.1%). The north region obtained the highest scores for both moderate (17.2%) and high-DE (9.7%), whereas the center-west region obtained the second place for moderate-DE (15.1%) and the center region for high-DE (11.5%). The center region showed the lowest scores for moderate-DE (11.5%) and the south-southeast region the lowest for high-DE (4.5%). The analysis across age showed a positive relationship for both moderate and high-DE. The total prevalence of DE was 6.8%. Age, socioeconomic status and the place of residence seem to be variables that relate to disordered eating.

    The XV Mexican School of Particles and Fields was held at Puebla, Mexico at The Old and beautiful building of the Colegio Carolino from 6-15 September 2013. It gathered more than 132 national physicists, and 10 from other countries. This school lasted seven days and consisted of pedagogical lectures, discussions and poster sessions. Experimental, and theoretical developments were presented by distinguished physicists; addressing the most recent results in particle and field physics. The school lectures included topics on collider physics, neutrino physics, physics beyond the standard model, astroparticle physics, effective theories among others. The highlight topic of the conference was the discovery of the new boson, announced on 4 July 2012 by the LHC. The discovery of a particle consistent with the long-sought Higgs boson, considered one of the most important discoveries of the 21st Century, was fully addressed. The particle represented the final piece of the standard model. The searching methods and latest results were extensively presented as well as the detector design. The physics implications of the discovery and the future of searches for physics BSM, like SUSY, were covered. The topical conference included: 'Recent results on Higgs' by John Ellis, 'The CMS experiment, Highlights and Performance' by Tiziano Camporesi (CMS spokesperson), and 'LHC physics program by Emilio' Meschi (LHC physics coordinator). For many of the participants, however, the highlight of the school may have been the Sunday excursion to the Large Millimeter Telescope and HAWC Observatory, two of the world's largest astrophysics experiments in their field. We thank all the lecturers for making this a timely and informative school. Thanks to all who encouraged the discussions and stimulated the flow of information during the question time and the discussion sessions.

    Full Text Available The objective of this research was to identify the school climate that prevails in the students of the faculty of Engineering and Architecture in a Mexican public University. This study was conducted in response to a need to take care of the recommendations of the agencies evaluating the educational programs. It was done with a quantitative approach, of a descriptive and correlational type with non-experimental transactional design. The studied dimensions of the school climate were: organization structure, functionality, pedagogical practices, climate between peer interaction and satisfaction. The data were collected using a Likert scale questionnaire, with a reliability of .880 of Cronbach’s Alpha coefficient and validity through confirmatory factorial analysis. The results obtained from the descriptive statistics pointed the favorable school climate in peer interaction and pedagogical practices. Organizational structure, however, was the lowest rated classroom climate dimension. ANOVA results showed significant statistical differences between the school climate and educational programs, the years that the students have remained in the university, the age and the school cycle. Pearson’s correlation analysis revealed weak and negative correlation between school climate and student age.

    The XI Mexican School on Particles and Fields took place on 2-13 August 2004, in the city of Xalapa, Veracruz, México. The School continued with the tradition of promoting High Energy Physics among the younger generation in Mexico. Thus, it was aimed specifically at graduate students and postdocs. The School consisted of several courses delivered by international experts on subjects of current interest to the scientific community. The length of each course was of six to eight hours, English being the language of instruction. A novelty in this edition of the School was its total duration (two weeks as opposed to one), the number of hours assigned to one subject, and the addition of some experimental courses for the students to overcome their inhibitions of a direct encounter with the equipment and its usage. There were also a few overview talks delivered by local experts on the current status of some of the research fields actively pursued in Mexico. The XI-MSPF was organized by the Particles and Fields Division of the Mexican Physical Society. It was generously sponsored by several institutions: Universidad de Veracruz, Universidad Nacional Autónoma de México, Universidad Michoacana de San Nicolás de Hidalgo, Centro de Investigaciones y Estudios Avanzados del IPN (CINVESTAV) and Consejo Nacional de Ciencia y Tecnología (CONACyT).

Due to the contribution of the Pan-American Health Organization, the association got together on a regular basis between 1959 and 1979 and the Mexican representatives participated in the discussions held to improve performance within schools and make sure they were all oriented towards the three main priorities: teaching, research and implementation of services in the community. Based upon this context, which was ruled by the OPS, we now analyze the role of the Mexican school in the generation of human resources for health and its performance within the context of Latin American Schools.

    Currently, there is limited evidence about effective strategies to manage childhood obesity and the metabolic syndrome in school settings. The present study aims to analyse changes in the prevalence of being overweight/obese and having the metabolic syndrome in relation to a 10-month lifestyle intervention based on individualised face-to-face sessions and parental education in school settings. The study sample comprised a cross-sectional sample of 96 overweight/obese Mexican children aged 6-12 years from eight schools. Clinical, anthropometric measurements and 24-h recalls were obtained during each of 13 visits. Laboratory measurements were determined at the beginning and end. The energy-reduced diet was based on dietary recommended intakes. Individualised structured daily meals and a physical activity plan, tailored-made for each child, were provided every 3 weeks at the schools. Parental attendance was required. Student's t-test, McNemar and Shapiro-Wilk tests and simple linear regression were used for the statistical analysis. The prevalence of metabolic syndrome fell significantly from 44% to 16% (P children, 32% achieved normal-weight, whereas 24% of the obese ones converted to overweight and 1% reached normal-weight. Physical activity increased 16 min/day(-1) (P = 0.02) and 2 days/week(-1) . A school-setting lifestyle intervention led to a decreased prevalence of being overweight/obese and to a striking reduction in the prevalence of the metabolic syndrome in a sample of Mexican children. © 2013 The Authors Journal of Human Nutrition and Dietetics © 2013 The British Dietetic Association Ltd.

    Full Text Available The aim of this article is to analyze the relationship between dropping out of school and the perceived quality of the last school that Mexican teenagers attended, and examine the interaction between this educational factor and the economic status of this population. Based on the 2010 National Youth Survey, the researchers used the life table to describe this relationship, and Cox regression models to analyze it, including individual, family-related and educational co-variables. The results show that the risk of dropping out of school is indirectly linked to school quality and, to a greater degree, to economic status; and that the gap between students dropping out based on school quality is slightly wider among adolescents of low academic status than among those of high status.

    Full Text Available Motivation studies have focused on three aspects that are important for their educational implications: relevant variables for assessing motivation to attend school; motivational differences between students with different academic performance, and changes in motivation as they advance in school. Considering these aspects, the present study was developed with these objectives: to develop, and to set up the validity and reliability of a psychometric instrument for investigating how people perceive different motivational variables regarding various school activities typical of the Mexican junior high school; and to find out whether there is a relationship between motivational variables and academic achievement, grade level and gender. The results indicate that academic performance is related to the way motivation is perceived, that students change their perception of motivation during their school life, and that boys and girls differ concerning this only in some respects.

    Full Text Available Background: Migration selectivity is thought to shape the health profiles of Mexican immigrants. Objective: This study examines how the experience of Mexican migration to the United States affects the health process and the quality of life in old age by age at migration, specific to sex. Methods: We use 20 years of data from the Hispanic Established Populations for the Epidemiologic Study of the Elderly to estimate the proportion of life spent disability-free prior to death across eight subgroups by sex, nativity, and age at migration among Mexican-origin elderly in the United States. Results: Female migrants are at a significant disadvantage in terms of IADL disability-free life expectancy relative to US-born women, particularly late-life migrants. Conversely, mid- and late-life male migrants exhibit an advantage in ADL disability-free life expectancy compared to their US-born counterparts. Conclusions: Foreign-born Mexican elders are not a homogeneous group. This issue merits special attention in the development of community-based long-term care programs in order to appropriately target the specific needs of different subgroups of older Mexican individuals entering their last decades of life. Contribution: This study contributes to immigrant health literature by providing a more comprehensive documentation of nativity differentials, by distinguishing subgroups of Mexican elderly by sex, nativity, and age at migration.

    Recently, multi-ethnic reference ranges for spirometry have been created for use worldwide. In comparison, forced oscillation technique (FOT) reference values are limited to specific equipment and study populations, with current FOT reference ranges created in a Caucasian population. We aimed to develop FOT reference ranges for preschool-aged Mexican children and to compare these with current FOT reference ranges. Respiratory resistance (Rrs) and reactance (Xrs) was measured in healthy Mexican children three to five years of age using commercial FOT equipment. The relationship between height and Rrs and Xrs was determined using regression analyses, taking into account age, weight, sex, and exposure to tobacco smoke. Reference equations were calculated for the Mexican children and Z-scores determined for Rrs and Xrs at 6 and 8Hz. A paired t-test assessed the difference in Z-scores between the Australian reference values and those created for the Mexican cohort. FOT was successfully measured in 584 children. Height was a significant predictor of Rrs and Xrs at 6 and 8Hz (Pchildren for both Rrs and Xrs at 6 and 8Hz (Pdevelopment of FOT reference ranges specific to Mexican preschool-aged children will allow for the correct interpretation of FOT measurements. This study also showed that current FOT reference ranges overestimate lung function in Mexican children.

Vital Aging® is a program that considers active aging as the lifelong adaptation process of maximizing health and independence, physical and cognitive functioning, positive affect regulation and control, and social engagement. Through its different versions and editions, it has demonstrated being an effective program to promote active aging. The aim of this study is to determine the effectiveness of the “face-to-face” and “combined” versions of the program to promote active aging in Mexican older adults trial. Methods: Seventy-six older adults aged 60 years and over participated in a quasi-experimental study and were recruited in a senior center to participate in the two experimental conditions: Vital Aging face-to-face (VA-FF (n=35 and Vital Aging combined (VA-C; multimedia/face-to-face (n=15, and the remaining 26 adults were assigned to a control group. Pretest and posttest assessments were performed after the theoretical–practical intervention. Mean differences and size effects were calculated for estimating the effect of the program. Results: At the end of the study, participants showed improvements in the active aging outcome measures. Positive effects were observed in the frequency of intellectual, cultural – artistic, and social activities, perceptions of aging, satisfaction with social relationships, and self-efficacy for aging. Additionally, those who participated in VA-FF showed better memory performance, meta-memory, and a trend to report less memory problems, while older persons in VA-C showed a trend to have better life satisfaction.

    The XIV Mexican School on Particles and Fields took place from 8-12 November, 2010, in the colonial city of Morelia, Michoacan, Mexico. The format of the school was such that the morning sessions were devoted to theoretical and experimental reviews, whereas parallel thematic sessions were held in the afternoons. All the reviews and seminars were delivered by experts of international prestige on subjects which are of current interest to the global scientific community and are also actively pursued within Mexico. In order to equip the attending graduate students and post docs with the necessary introductory tools to allow them to benefit substantially from the specialized seminars, a series of mini-courses were offered prior to the event from 4-7 November 2010, in the Auditorium of the Faculty of Science of the University of Michoacan (UMSNH). The length of each course was about 5 hours, English being the language of instruction. An informal and friendly atmosphere was encouraged during the courses so that the students could overcome their inhibitions and actively participate in the discussions. A novel feature of this event was a colloquium aimed at the general public and younger students of pre-undergraduate level, which allowed the expert scientists to reach out to a wider community and raise their awareness and interest in one of the most fascinating and vital fields of knowledge. The XIV-MSPF was organized by the Division of Particles and Fields of the Mexican Physical Society. It was generously sponsored by several institutions: Consejo Estatal de Ciencia y Tecnológico (COECyT) del Estado de Michoacán, Universidad Michoacana de San Nicolás de Hidalgo, Universidad de Sonora, Universidad Nacional Autónoma de México, Universidad de Guanajuato, Universidad de Sinaloa, Centro de Investigaciones de Estudios Avanzados del IPN (CINVESTAV), Consejo Nacional de Ciencia y Tecnología (CONACyT), la Academia Mexicana de Ciencias and, most importantly, the Red Nacional

    Full Text Available Objective. To identify dental pain prevalence and associated factors in Mexican schoolchildren. Methods. This cross-sectional study included 1,404 schoolchildren aged 6 to 12 years from public schools in the city of Pachuca de Soto, Hidalgo, Mexico. Data were collected through a questionnaire that addressed sociodemographic and socioeconomic factors, eating and dental hygiene habits, and behavior variables. The dependent variable was self-reported dental pain in the 12 months prior to the survey. Data were analyzed using nonparametric statistics and a binary logistical regression model. Results. Dental pain prevalence among the studied children was 49.9%. The variables associated in the final model (p<0.05 were younger mother’s age, higher socioeconomic level, absence of an automobile in the home, fried food, fruit intake, lower tooth brushing frequency, never having used mouthwash or not knowing about it, and parents/guardians with regular to high levels of knowledge about oral health and a regular or good/very good perception of their child’s oral health. Conclusions. One in two children in the study had experienced dental pain in the twelve months prior to the survey. The association of socioeconomic variables with dental pain suggested inequalities among the children in terms of oral health.

    Objective To describe the third wave of the Mexican Health and Aging Study (MHAS), completed in 2012, and present preliminary results. Materials and methods Descriptive analyses by gender and age group of demographic and socioeconomic characteristics, health conditions and health behaviors, as well as social support and life satisfaction measures are presented. In addition, external validations are presented by comparing MHAS 2012 indicators with other national data sources. Results For the panel of older adults in the sample, the rate of health care insurance coverage increased greatly between 2001 and 2012, a significantly higher change in rural compared to urban areas. The results for 2012 are consistent with the previous two waves for the main indicators of health and physical disability prevalence, risk factors, and behaviors. Conclusions The MHAS offers a unique opportunity to study aging in Mexico, as well as to complete cross-national comparisons. The cumulative number of deaths in the cohort should support the study of mortality and its association with health outcomes and behaviors over the life cycle. In addition, the sub-samples of objective markers will enable methodological research on self-reports and associations of biomarkers in old age with similar health outcomes and behaviors.

    This study aimed to explore the attitudes and behaviors of Latino mothers around feeding their children. Using qualitative methods, we conducted four focus groups in Spanish with 41 Latino mothers of elementary school-age children in San Diego County, CA. Latino mothers' mean age was 41 years; 90% were foreign-born; and 74% had a high school education or less. We explored cultural viewpoints around feeding and cooking and feeding strategies used. Focus groups were analyzed based on a priori and emergent themes. The following themes around feeding emerged: feeding attitudes central to the maternal responsibility of having well-fed children and feeding behaviors that centered on cooking methods, supportive behaviors, and reinforcement strategies for "eating well." These findings increase our understanding of the Latino maternal role to feed children and can help to inform more culturally appropriate research to effectively address nutritional issues and obesity prevention in Latino children.

    School bullying incidents, particularly experiences with victimization, are a significant social and health concern among adolescents. The current study extended past research by examining the daily peer victimization experiences of Mexican-American adolescents and examining how chronic (mean-level) and episodic (daily-level) victimization incidents at school are associated with psychosocial, physical and school adjustment. Across a two-week span, 428 ninth and tenth grade Mexican-American students (51 % female) completed brief checklists every night before going to bed. Hierarchical linear model analyses revealed that, at the individual level, Mexican-American adolescents' who reported more chronic peer victimization incidents across the two-weeks also reported heightened distress and academic problems. After accounting for adolescent's mean levels of peer victimization, daily victimization incidents were associated with more school adjustment problems (i.e., academic problems, perceived role fulfillment as a good student). Additionally, support was found for the mediation model in which distress accounts for the mean-level association between peer victimization and academic problems. The results from the current study revealed that everyday peer victimization experiences among Mexican-American high school students have negative implications for adolescents' adjustment, across multiple domains.

    In developing countries, more than 50% of children have serological evidence of Helicobacter pylori infection. However, serological tests for H. pylori did not differentiate between active and past infection. The objectives of this study were to estimate the frequency of active and past H. pylori infection utilizing functional urea breath test (UBT) and serological tests and evaluate factors associated with the infection. A total of 675 school children, 6-13 years of age, participated. UBT was performed to detect active H. pylori infection. Blood samples were obtained to determine iron status and Immunoglobulin G (IgG) responses to the H. pylori whole-cell and to Cag A antigens by antigen-specific enzyme-linked immunosorbent assays. Weight, height, and sociodemographic characteristics were recorded. A total of 37.9% (95% Confidence Intervals (CI): 34.2-41.6) of school children had active or past H. pylori infection; of them, 73.8% (CI95% 68.4-79.2) were carrying CagA-positive strain, 26.5% (CI95% 23.2-29.8) had active infection, and 11.4% (95%CI: 9.0-13.8) had evidence of past H. pylori infection. School children with iron deficiency and low height for age had higher risk of H. pylori infection: [OR to active or past infection was 2.30 (CI 95% 1.01-5.23) and to active infection it was 2.64 (CI 95% 1.09-6.44)] compared to school children with normal iron status and height for age or with normal iron status but low height for age or with iron deficiency and normal height for age. The estimated prevalence of infection depends of the test utilized. Frequency of H. pylori infection and carrying CagA-positive strains was high in this population. Malnutrition was associated with active H. pylori infection. © 2013 John Wiley & Sons Ltd.

MATERIAL AND METHODS: Overweight and obesity (defined as an excess of adipose tissue in the body were evaluated through the Body Mass Index (BMI in 10,901 children, using the standard proposed by the International Obesity Task Force. Sociodemographic variables were obtained using a questionnaire administered to the children's mothers. RESULTS: The national prevalence of overweight and obesity was reported to be 19.5%. The highest prevalence figures were found in Mexico City (26.6% and the North region (25.6%. When adjusting by region, rural or urban area, sex, maternal schooling, socioeconomic status, indigenous ethnicity and age, the highest prevalences of overweight and obesity were found among girls. The risks of overweight and obesity were positively associated with maternal schooling, children's age and socioeconomic status. CONCLUSIONS: Overweight and obesity are prevalent health problems in Mexican school-age children, particularly among girls, and positively associated with socioeconomic status, age, and maternal schooling. This is a major public health problem requiring preventive interventions to avoid future health consequences.OBJETIVO: Documentar las prevalencias de sobrepeso y obesidad en niños mexicanos en edad escolar (5 a 11 años de edad obtenidas de la Encuesta Nacional de Nutrición en 1999 (ENN-1999.

    To distinguish the origins of higher weight status and determine when and why intra- and interracial/ethnic disparities emerge. The study used a longitudinal analysis of the Early Childhood Longitudinal Study-Birth Cohort (ECLS-B). The study was conducted in the United States. Participants were children of non-Hispanic white mothers and children of U.S.- and foreign-born mothers of Mexican origin from a nationally representative sample of children born in the year 2001 (N ≈ 3700). The Centers for Disease Control and Prevention growth charts determined sex- and age-specific weight status. Covariates were obtained from birth certificate records and parent interviews. Frequencies, growth curve trajectories, and ordinary least squares regression examined body mass index (BMI) and obesity across survey waves. Compared to their peers with non-Hispanic white mothers, children of Mexican-heritage mothers have higher average BMI and greater rates of obesity. The BMI of boys with Mexican-born mothers is higher relative to whites and children of U.S.-born Mexican mothers across early childhood, increasing sharply at about age 4.5 years. This divergence is driven by increases in the BMI of boys, as girls do not show the same growth. A number of measures, including descriptors of children's nutritional intake, lifestyle factors, and acculturation, do not explain the increased obesity rates among sons of Mexican mothers. Despite favorable perinatal health and weight, Mexican-American sons of foreign-born mothers show disadvantages in BMI that emerge close to the start of kindergarten. © 2016 by American Journal of Health Promotion, Inc.

    The childhood obesity epidemic is a global concern. There is limited evidence in Mexico linking the local food environment to obesity. The purpose of this study is to describe the links between the local food environment around elementary schools and schoolchildren's BMI in two Mexican cities. Cross-sectional surveys were conducted in 60 elementary schools in two Mexican cities (i.e., Cuernavaca and Guadalajara) in 2012-2013. Anthropometric measurements on schoolchildren were collected, as well as environmental direct audits and observations in a 100-m buffer around schools. Children's BMI was evaluated according to WHO-recommended procedures. In BMI models, the explanatory variable was the number of retail food sources. These models were adjusted for child's characteristics, schools' socioeconomic background, compliance with federal guidelines concerning unhealthy foods within schools' facilities, and corresponding city. Analysis was conducted in 2014. The number of mobile food vendors was higher around public schools than outside private schools (pschools. Schoolchildren from the highest tertile of mobile food vendors showed 6.8% higher BMI units than those from the lowest tertile. Children attending schools within the highest tertile of food stores also had 4.7% higher BMI units than children from schools in the lowest tertile. Health policy in Mexico should target the obesogenic environment surrounding elementary schools, where children may be more exposed to unhealthy foods.

    This 5-year follow-up of a randomized clinical trial evaluated the efficacy of a family-focused intervention delivered in middle school to increase school engagement following transition to high school (2 years post-test), and also evaluated mediated effects through school engagement on multiple problem outcomes in late adolescence (5 years post-test). The study sample included 516 Mexican American adolescents who participated in a randomized trial of the Bridges to High School Program (Bridges/Puentes). Path models representing the direct and indirect effects of the program on four outcome variables were evaluated using school engagement measured in the 9th grade as a mediator. The program significantly increased school engagement, with school engagement mediating intervention effects on internalizing symptoms, adolescent substance use, and school dropout in late adolescence when most adolescents were in the 12th grade. Effects on substance use were stronger for youth at higher risk based on pretest report of substance use initiation. There were no direct or indirect intervention effects on externalizing symptoms. Findings support that school engagement is an important prevention target for Mexican American adolescents.

    Research on the health consequences of long-term injection drug use (IDU) is limited. This article examines these consequences among aging, male Mexican American injecting heroin users. Concern for this group is crucial, given its health disparities and the association of IDU with disease transmission. Aging, male Mexican American IDUs (N = 227) were recruited through intensive outreach. Participants self-reported health status, medical and substance use history, and completed behavioral and psychometric health scales. Results: Participants had significantly poorer self-rated health and negative health conditions. Selected medical conditions not associated with the heroin-use lifestyle (i.e., hypertension, diabetes, arthritis) were lower relative to the comparison samples. This population has a complex profile of health consequences linked to a heroin-using lifestyle. The study concludes that routine screening of infectious diseases and medical and behavioral conditions among aging substance using populations may contribute to reducing Hispanic health disparities.

    To determine the association between overweight and obesity among Mexican school-aged children and participation in the Liconsa milk and the School Breakfast food assistance programs. Data from 15 003 school-aged children included in the Mexican National Health and Nutrition Survey 2006 (ENSANUT 2006) were analyzed. Information on body mass index (BMI) and participation in food assistance programs was obtained. Descriptive analyses were conducted and logistic regression models were adjusted. Prevalence of overweight and obesity was 17.3% and 9%, respectively. No significant association between overweight and obesity and participation in Liconsa was found. Among school-aged children in the middle socioeconomic status quintile, those enrolled in the School Breakfast program were more likely to be overweight than those not enrolled (OR= 1.6, 95% CI 1.1, 2.3). We found no association between the Liconsa and the School Breakfast programs and overweight or obesity in school-aged children.

    The current study aimed to determine the differences between sleep-wake habits and circadian preference in Mexican adolescents attending classes at a morning shift or an afternoon shift. The sample consisted of 568 students of a secondary school in Reynosa, northeastern Mexico, of whom 280 were boys and 288 were girls (mean age 14.08 ± 0.72 years, age range 13-16 years). In the morning shift, 287 students attend classes on a schedule from 7:30 to 13:00 and the afternoon shift, 281 students, on a schedule from 13:20 to 19:00. Students completed a general information questionnaire, the Sleep Timing Questionnaire and the Spanish version of the Morningness-Eveningness Questionnaire. The adolescents who attended the morning shift had earlier bedtime and waking time, but shorter sleep duration than those who attended the afternoon shift. Those oriented to eveningness had later bedtime, waking time, and a shorter sleep duration than those oriented to morningness. Two interactions were found between school shift and chronotype. First, with regard to waking time during weekdays, students who attended the afternoon shift and were oriented to eveningness woke up later than those who attended the morning shift and were oriented to eveningness; during weekdays, there were no differences between the waking time of morning-type and evening-type students who attended the morning shift. Second, with regard to sleep duration on weekdays, students who attended the morning shift and were oriented to eveningness had the shortest sleep duration. Furthermore, there were no differences between sleep duration on weekdays in evening-type and morning-type students of the afternoon shift. Adolescents who attend classes in the morning shift and are oriented to eveningness are the most sleep deprived. Those who attend the afternoon shift will have optimal sleep duration, regardless of their circadian preference. Copyright © 2015 Elsevier B.V. All rights reserved.

    This study evaluated 24-month outcomes of a school-based intensive lifestyle weight management program targeting overweight Mexican-American adolescents. We recruited a total of 71 adolescents (32 males; 45.1%) between the ages of 10 and 14 years, at or above the 85th percentile for body mass index (BMI). Participants were randomized to a 6-month instructor-led intervention (ILI) or a self-help (SH) program. Both interventions were aimed at modifying eating and physical activity behaviors using behavior modification strategies. We assessed changes in participants' standardized BMI and BMI percentile at baseline, 1, and 2 years. Repeated-measures analyses showed that ILI participants showed significantly greater decreases in standardized BMI at 1 and 2 years (F = 8.58, p school-based intervention resulted in improved weight outcomes in overweight Mexican-American adolescents and results were maintained over 2 years.

    To analyze the current situation of teaching occupational medicine (OM) in academic programs and medical schools in Mexico. A descriptive survey was conducted and schools were identified through the main directories of medical schools. For the analysis of information descriptive and inferential statistics were used. A total of 75 medical schools were identified. In 39 (52%) the subject is mandatory, with a predominance in public schools (pschools that offer the subject, only 15 (38%) have professors specialized in OM. Disparity in teaching basic aspects of OM in medical schools explains the little development and social and professional recognition of the specialty; it also highlights serious problems for public health, derived from the lack of prevention of risks in work environments.

    We examined whether acculturation and immigrant generation, a marker for assimilation, are associated with diabetes risk in an aging Mexican-origin population. We analyzed data on 1789 adults aged 60 to 101 years from the Sacramento Area Latino Study on Aging. We ascertained type 2 diabetes on the basis of diabetic medication use, self-report of physician diagnosis, or a fasting glucose of 126 milligrams/deciliter or greater. Logistic regression modeled prevalent diabetes. Adjusting for age and gender, we observed significant but divergent associations between immigrant generation, acculturation, and diabetes risk. Relative to first-generation adults, second-generation adults had an odds ratio (OR) of 1.8 (95% confidence interval [CI] = 1.4, 2.4) and third-generation adults had an OR of 2.1 (95% CI = 1.4, 3.1) of having diabetes. Greater US acculturation, however, was associated with a slightly decreased diabetes rate. In the full model adjusting for socioeconomic and lifestyle factors, the association between generation (but not acculturation) and diabetes remained significant. Our study lends support to the previously contested notion that assimilation is associated with an increased diabetes risk in Mexican immigrants. Researchers should examine the presence of a causal link between assimilation and health more closely.

    This paper uses register-based data to investigate the effects of school starting age on crime. Through this, we provide insights into the determinants of crime-age profiles. We exploit that Danish children typically start first grade in the calendar year they turn seven, which gives rise...... to a discontinuity in school starting age for children born around New Year. Our analysis speaks against a simple invariant crime-age profile as is popular in criminology: we find that higher school starting age lowers the propensity to commit crime at young ages. We also find effects on the number of crimes...

    To examine the association between life-space mobility and cognitive decline over a five-year period among older Mexican Americans. Longitudinal study. Hispanic Established Population for the Epidemiologic Study of the Elderly survey conducted in the southwestern of United States (Texas, Colorado, Arizona, New Mexico, and California). Four hundred thirty-two Mexican Americans aged 75 and older with normal or high cognitive function at baseline. Socio-demographic factors, living arrangement, type of household, social support, financial strain, self-reported medical conditions, Mini-Mental State Examination (MMSE), depressive symptoms, activities of daily living (ADLs), and Short Physical Performance Battery. Life-space assessment (LSA) during the past 4 weeks was assessed during in-home interview. Scores ranged from 0 (daily restriction to the bedroom) to 120 (daily trips outside of their own town without assistance) and categorized as 0 to 20, 21 to 40, 41 to 60, 61 to 80, and 81 to 120. Because of the small sample size in the category of 81 to 120, the two highest categories were combined into a single group. The mean LSA score and MMSE score of participants at baseline was 44.6 (Standard Deviation [SD], 20.7) and 25.7 (SD, 3.2), respectively. Mixed Model analyses showed that participants in the highest life-space category (≥61) experienced slower rates of cognitive decline over time compared to participants in the lowest category (0 to 20) (β = 1.03, Standard Error [SE] = 0.29, P = 0.0004), after adjusting for all covariates. Greater life-space mobility at baseline was predictor of slower rates of cognitive decline over 5 years in older Mexican Americans. © 2017, Copyright the Authors Journal compilation © 2017, The American Geriatrics Society.

  10. Precautionary Savings in Mexico: Evidence from the Mexican Health and Aging Study.

    Science.gov (United States)

    Velandia Naranjo, Durfari; van Gameren, Edwin

    2016-06-01

    Precautionary saving is the additional saving done by individuals to protect them financially in situations of uncertainty and reduce their vulnerability for negative shocks that may affect their consumption levels. This paper investigates the existence and extent of savings motivated by precaution in Mexico for people aged between 50 and 75, using data from the Mexican Health and Ageing Study 2003. The empirical strategy is based on a test of the direct relationship between the accumulated wealth and the uncertainty generated by the social security status, in particular the availability of health insurance, accounting also for the expectation to receive a retirement pension. The endogeneity-corrected estimates do not yield results that unequivocally support the existence of private savings as a risk protection mechanism, implying that the public protection system has an important role in reducing the vulnerability of the population studied.

    2015-01-01

    The purpose of this study was to explore in rural communities of Mexico, the association between physical activity (PA) in school-age children and exposure to migration. We measured PA through a questionnaire validated in school-age children and used in Mexican National Surveys. Migration status was measured as the number of years a family member had been in the US, and the amount of remittances that family member had sent to their household in Mexico. We used multivariable linear regression to measure the association between physical activity and migration. School-age children who had a migrant family member spent less time on PA per day, especially recreation activities, compared to school-age children without the migrating influence. Also, children who belonged to a family that received remittances and their migrant relative lived ≥ 5 years in US were less likely to engage in PA. Exposure to migration may predict reduction in PA in school-age children left behind in Mexican rural communities from the State of Morelos. These findings call for PA-tailored interventions that consider household migration characteristics.

    To evaluate the independent and joint effects of dietary folate, vitamin B(12) consumption and methylenetetrahydrofolate reductase (MTHFR) polymorphisms (677C>T and 1298A>C) on the circulating folate and homocysteine (Hcy) levels among Mexican women of reproductive age. A cross-sectional, population-based study. The first 130 healthy non-pregnant women (aged 16-34 years) who agreed to participate in a reproductive cohort in Morelos, Mexico. Dietary intakes of vitamin B(12) and folate were estimated using a semiquantitative food frequency questionnaire. MTHFR 677C>T and 1298A>C polymorphisms were ascertained using the PCR-based method. Serum levels of Hcy and folate were determined using high-performance liquid chromatography and radioimmunoassay, respectively. Genotype frequencies for the MTHFR 677C>T polymorphism were 21.5% (CC), 52.3% (CT) and 26.2% (TT) among Mexican women. Of the population, 22% had the MTHFR 1298AC genotype, while no individual carried the 1298CC genotype. We observed an increased level of Hcy among carriers of the 677TT genotype, compared to carriers of the 677CC genotype. The highest level of Hcy was observed among MTHFR 677TT carriers with low B(12) intake (<2.0 microg/day), which resulted with a significant interaction (P=0.01). Vitamin B(12) is an important determinant of Hcy levels in Mexico. Supplementation of folic acid with vitamin B(12) may be preferable when the MTHFR 677T variant allele is prevalent.

    The relation between cultural socialization and ethnic pride during the transition to middle school was examined for 674 fifth-grade students (50% boys; Mage = 10.4 years) of Mexican origin. The theoretical model guiding the study proposes that parent-child relationship quality is a resource in the transmission of cultural values from parent to child and that parental warmth promotes the child's positive response to cultural socialization. Results showed that mother and father cultural socialization predicted youth ethnic pride and that this relation was stronger when parents were high in warmth. The findings highlight the positive role parent cultural socialization may play in the development of adolescent ethnic pride. Furthermore, findings reveal the role of parent-child relationship quality in this process. © 2013 The Authors. Child Development © 2013 Society for Research in Child Development, Inc.

    Describe the Estudio Nacional de Salud y Envejecimiento en México (ENASEM), also known by its name in English as the Mexican Health and Aging Study (MHAS). This article summarizes the study design, its fieldwork protocol, survey contents, scope and analytical potential. It also presents descriptive results on selected topics. This is a prospective panel study on persons aged 50 or older in the year 2000. In the baseline survey, completed in 2001 with a national and urban-rural representation, about 15 200 interviews were completed. In the follow-up survey of the same persons in 2003, 90% of the attempted contacts resulted in successful interviews, and 546 interviews were completed about individuals who had died between the 2001 and 2003 visits. Descriptive results are presented on demographic characteristics, health, life style, institutional support, pensions, employment, family help, and two-year changes in health. There is evidence of large heterogeneity among older adults in Mexico, which is illustrated in a brief and precise way in the results presented. This study and its data bases have great analytical potential for exploring multiple dimensions in the health of older adults.

    2016-02-01

    Research reveals that people tend to place greater value on emotional support as they move through the life course. Older people are likely to do so because emotional support benefits them in some way. The purpose of this study was to see whether there are age differences in the relationship between emotional support and the number of chronic health conditions. In the process, an effort is made to contribute to the literature in three ways. First, an emphasis placed on assessing the relationship between emotional support and health within late life. Second, variations in the source of support are taken into account by contrasting support within religious institutions with support that is received outside church. Third, these issues are examined with data provided by a nationally representative sample of older Mexican Americans (N = 663). The findings suggest that age differences in the relationship between emotional support and health are present within late life. Moreover, the data indicate that this relationship holds for church-based social support but not support that is received outside the church.

    To assess the prevalence of IgG antibodies against Group B streptococci (GBS) among women of reproductive age in Mexico. Serum specimens were drawn from 15 to 40 year-old women, representative of all regions and socioeconomic levels of the country. The sample was randomly selected from Banco Nacional de Sueros (National Sera Bank); serum samples were collected during a national seroepidemiologic survey conducted in 1987-1988. The assays for standardization and for evaluation of seroprevalence were carried out at the Hospital de Pediatría del Centro Médico Nacional Siglo XXI (Children's Hospital) Instituto Mexicano del Seguro Social (IMSS) (Mexican Institute of Social Security) from January to November 1995. IgG antibodies against group B antigen were studied with an enzyme-linked immunosorbent assay (ELISA) developed in our lab. Group B antigen was produced and purified from the reference strain GBS 110. A total of 2669 serum samples were studied; 2405 were positive to anti-group B antigen IgG antibodies, for a seroprevalence of 90.2%. No differences in prevalence were found among the different age groups or among the different states of the country. The high seroprevalence of antibodies against GBS suggests that young women in Mexico are commonly exposed to GBS infection.

    The Satisfaction with Life Scale (SWLS) has been widely used and has proven to be a valid and reliable instrument for assessing satisfaction with life in diverse population groups, however, research on satisfaction with life and validation of different measuring instruments in Mexican adults is still lacking. The objective was to evaluate the psychometric properties of the Satisfaction with Life Scale (SWLS) in a representative sample of Mexican adults. This is a methodological study to evaluate a satisfaction with life scale in a sample of 13,220 Mexican adults 50 years of age or older from the 2012 Mexican Health and Aging Study. The scale's reliability (internal consistency) was analysed using Cronbach's alpha and inter-item correlations. An exploratory factor analysis was also performed. Known-groups validity was evaluated comparing good-health and bad-health participants. Comorbidity, perceived financial situation, self-reported general health, depression symptoms, and social support were included to evaluate the validity between these measures and the total score of the scale using Spearman's correlations. The analysis of the scale's reliability showed good internal consistency (α = 0.74). The exploratory factor analysis confirmed the existence of a unique factor structure that explained 54% of the variance. SWLS was related to depression, perceived health, financial situation, and social support, and these relations were all statistically significant (P life satisfaction between the good- and bad-health groups. Results show good internal consistency and construct validity of the SWLS. These results are comparable with results from previous studies. Meeting the study's objective to validate the scale, the results show that the Spanish version of the SWLS is a reliable and valid measure of satisfaction with life in the Mexican context.

    Full Text Available This study focuses on the research area of scholastic efficacy. It postulates the existence of certain characteristics of schools which have a personal and significant effect on the scholastic achievement of their students. In particular, the work falls into the category of studies on school effects. The effect of the school is defined as the proportion of the variance of the scholastic achievement results attributable to school policies and practices. The purpose of the study is to estimate the magnitude of the school’s effect, i.e. the relative contribution of the school in the total variation of academic achievement in Spanish and Mathematics in the three grades of the Mexican junior high school. The data employed come from the National Standard Tests for 2002 and 2003, applied to a national sample of junior high schools in Mexico. The analysis was performed with the HLM program, using Multilevel Models. The work was done with a model of two levels (student and school. The research, which is descriptive and correlational, contributes explanatory elements based on the analyses made. The key findings are these: a The estimated effect of the school through the intraclass correlation index (ICI was 12% for Spanish and 9% for Mathematics, which means that the Mexican junior high schools are quite similar to each other. Although it may seem paradoxical, we have confirmed that this effect, numerically speaking, is sufficient for us to say that the school which students attend makes the difference. b In comparing scholastic effects between the junior high schools’ modalities of operation, it was found that in the case of Mathematics, the telesecundarias (junior high schools conducted by Internet have a greater effect on student performance than do general and technical public schools, or private schools, in both Spanish and Mathematics.

    The aim of this article is to establish the association between beliefs about healthy habits and mortality in a group of Mexican older adults. This is an 11-year follow-up secondary analysis of the Mexican Health and Aging Study. There was a significant difference ( p healthy habits have the potential to improve health compared with those who did not. After adjustment for confounders, Cox regression models showed a hazard ratio (HR) of 0.17 (95% confidence interval [CI] [0.07, 0.38], p healthy habits. Although the mechanism is not completely clear, according to our results, believing that healthy habits can improve health was associated with lower rates of mortality. Further research should elucidate potential strategies for changing beliefs in older adults with the goal of improving their overall health.

    Little research has examined how chronic stress in different domains relates to allostatic load (AL). We examined the relationship between multiple chronic stressors with AL, and evaluated lifestyle factors as possible mediating factors. Three hundred one middle-aged Mexican-American women underwent a physical exam and completed measures of lifestyle factors and chronic stress in eight domains. A composite of 12 neuroendocrine, metabolic, cardiovascular, and inflammatory markers represented AL. Chronic work, financial, and caregiving domains related to higher AL scores after adjusting for covariates and other stressors. Lifestyle factors made little contribution to the association between stressors and AL. Chronic work, financial, and caregiving stressors are associated with physiological dysregulation in Mexican-American women. This study is among the first to examine multiple domains of chronic stress in relation to AL, in a population that has been understudied in research concerning stress and health.

    The collection of papers in this volume was presented during the X Mexican School on Gravitation and Mathematical Physics, which was held in Playa del Carmen, Quintana Roo, México, December 1-5, 2014. The Mexican School on Gravitation and Mathematical Physics is a series of conferences sponsored by the Mexican Physical Society that started in 1994 with the purposes of discussing and exchanging current ideas in gravitational physics. Each Mexican School has been devoted to a particular subject, and these have included supergravity, branes, black holes, the early Universe, observational cosmology, quantum gravity and numerical relativity. In this ocasion the theme of the school was Reaching a Century: Classical and Modified General Relativity's Attempts to explain the evolution of the Universe, which focused on the discussion of classical and modified aspects of general relativity. Following our previous Schools, world leaders in the field were invited to give courses and plenary lectures. More specialized talks were also presented in parallel sessions, and some of them have been included in these proceedings. The contributions in this volume have been reviewed and represent some of the courses, plenary talks and contributed talks presented during our X School. We are indebted to the contributors of these proceedings as well as to the rest of the participants in our Mexican School all for making of it a complete success. As for financial support we should mention the Mexican National Science and Technology Council (CONACyT), the Royal Society of London (UK), the Mexican Physical Society (SMF), as well as several Institutions including: Centro de Investigación y Estudios Avanzados (CINVESTAV), Universidad Autónoma Metropolitana Iztapalapa (UAM-I), Universidad de Guanajuato (UG), and Universidad Nacional Autónoma de México (UNAM).

    This paper reports a qualitative research that identifies Mexican high school students' social representations of mathematics. For this purpose, the social representations of 'mathematics', 'learning mathematics' and 'teaching mathematics' were identified in a group of 50 students. Focus group interviews were carried out in order to obtain the data. The constant comparative style was the strategy used for the data analysis because it allowed the categories to emerge from the data. The students' social representations are: (A) Mathematics is…(1) important for daily life, (2) important for careers and for life, (3) important because it is in everything that surrounds us, (4) a way to solve problems of daily life, (5) calculations and operations with numbers, (6) complex and difficult, (7) exact and (6) a subject that develops thinking skills; (B) To learn mathematics is…(1) to possess knowledge to solve problems, (2) to be able to solve everyday problems, (3) to be able to make calculations and operations, and (4) to think logically to be able to solve problems; and (C) To teach mathematics is…(1) to transmit knowledge, (2) to know to share it, (3) to transmit the reasoning ability, and (4) to show how to solve problems.

    Full Text Available Teachers’ attitudes play an important role in the implementation of educational reforms and innovations (Avramidis & Norwich, 2002; Fullan, 2001; Rogers, 2003; Waters, 2009; Wedell, 2009. Desired changes can successfully go through only if teachers respond positively to putting into effect those changes. Mexico is at present facing the challenge of an educational reform in basic education that involves adopting a new English as a second language program. Information about teachers’ attitudes towards the change is crucial to anticipate possible ways in which the process could unfold. This study explores the use of Appraisal Theory (Martin & White, 2005 to examine the linguistic expressions of attitude toward the Mexican National English Program for Basic Education. Data came from 12 focus group discussions conducted as part of a state-wide project with 86 secondary school teachers and supervisors in the northeastern corner of the country. Findings indicate that teachers’ negative attitudes towards the program were associated to their negative evaluation of the procedures to disseminate information about the program, and the quantity and quality of teacher training. Findings also shed light on the conventions related to the roles that teachers and administrators play in the reform implementation process. Implications of the findings are briefly discussed.

  1. Examining the career development of Mexican American middle school students: A test of social cognitive career theory

    Navarro, Rachel Leah

    This study tested portions of Lent, Brown, and Hackett's (1994) Social Cognitive Career Theory (SCCT) in the domain of mathematics and science with a sample of Mexican American middle school students. Results supported a modified path model. This study's findings supported several SCCT propositions regarding the positive relationships among background contextual affordances, learning experiences, self-efficacy, outcome expectations, interests, and goals. However, findings suggested that the influence of person inputs (i.e., gender and generational status) and some background contextual affordances (i.e., acculturation level) on learning experiences may be not be direct; instead, an indirect effect via a relationship with other background contextual affordances (i.e., perceived social support and social class) was found. Furthermore, results supported direct effects of gender on self-efficacy and learning experiences on goal intentions---two relationships not posited in SCCT. Implications for future research and counseling with Mexican American adolescents are discussed.

    nutritional intake and status of soccer players has attracted not much research attention. Many soccer players follow an inadequate nutritional intake and have a poor nutritional status. This is relevant in youngsters soccer players, in order to improve performance and promote healthy dietary practices. analyze anthropometric characterizes, evaluate nutritional intake and status, dietary habits and pre- and post-exercise meals in elite teenagers soccer players. seventy-two young male soccer players (15-20 years) from four junior teams of a soccer Club from the Mexican National Soccer League were measured for height, seat height, weight, 6 skinfolds, 6 diameters and 7 circumferences, height-for-age and BMI-for-age values. Skin, adipose, muscle, bone and residual tissue masses were calculated with the Ross and Kerr equation. Resting energy expenditure and intake was also measured. Daily dietary intake was self-recorded for 4 consecutive days (excluding the match day) using a digital food-weighing scale and a food record questionnaire. Dietary analysis was performed using the NutriBase 7 Clinical software. Several biochemical values were determined. One-way analysis of variance (ANOVA) and post hoc testing was performed using t-tests with a Bonferroni correction. all soccer players were within the normal range values for anthropometric parameters studies, when compared with other adolescent elite soccer teams. Values of plasma glucose, urea, creatinine, uric acid, lipid profile and total proteins were within normal range for young adult population, although albumin levels were high. Moreover, 14% and 20% of soccer players presented hyperuricemia and elevated total cholesterol levels respectively. Energy expenditure and intake were within normal range for all teenager elite soccer players. However, two teams shower significant lower intakes than demands. All macronutrient intakes were within recommendations, except protein that was higher. Micronutrient intake exceeded

    Children of Mexican immigrants are exposed to multiple ecological risks that heighten their likelihood of experiencing depressive symptoms. In previous studies, affirming parent-child communication has been found to be protective against depressive symptoms in Hispanic youth. Interventions focused on enhancing communication between parents and youth have the possibility of strengthening protective factors for children. The aims of this study were to (1) adapt an evidence-based parent-child communication intervention (Mission Possible) for cultural relevance for low-income, low-literacy Mexican immigrant mothers and their children and (2) assess feasibility of delivering the adapted intervention in a school setting. Adaptation took place in a series of focus groups of mother-child dyads. The revised intervention was delivered to 27 mother-child dyads in two elementary schools. Feasibility was supported by high participant satisfaction, 80% attendance rate, and 75% retention rate. This preliminary work suggests strategies for school nurses to partner with immigrant families and outlines a potential intervention that expands the school nursing role.

    Full Text Available School dropout has significant consequences for both individuals and societies. Only 21% of adults in Mexico achieve the equivalent of a high school education. We examined the relationship between school dropout and self-reported psychiatric symptoms in a middle school in a suburb of Mexico City. We used binomial logistic regression to examine the odd ratio of school dropout associated with student’s self-reported psychopathology. Two-hundred thirty seven students participated in the study. Psychosis (Odds Ratio (OR=8.0 (95% Confidence Interval (CI: 1.7-37.2, depression (OR=4.7 (95% CI: 2.2-9.7, tic disorders (OR=3.7 (95%CI: 1.4-9.5, ADHD (OR=3.2 (95%CI:1.5-6.4, and social phobia (OR=2.6 (95%CI: 1.2-5.8 were associated with increased risk of school dropout after controlling for age and gender as covariates. Our study suggested that students’ self-reported psychopathology is associated with increased school dropout in Mexico.

This study used a pretest-posttest, no control group, mixed-measures design to study 66 Mexican-American adolescents (mean age, 13.4 ± 5 years). Two plays containing subtle and overt signs of control and abuse were written and performed. Scripts were based on data from prior studies of TDV among Latino and Latina adolescents. At baseline, we measured sociodemographics, personal safety, and ethnic identity. Pre-post instruments measured acceptance of TDV, confidence to resolve conflicts nonviolently, and intentions to use nonviolent strategies to resolve conflict. We collected qualitative data via essay. At posttest, participants had less acceptance of TDV (t = -2.08; p Theater of the Oppressed was an effective way to interact with Latino adolescents. In a safe setting, participants vicariously experienced TDV, which facilitated self-reflection and cognitive rehearsal strategies to respond nonviolently to TDV.

    Full Text Available To address molecular mechanisms underlying obesity development, we examined patterns of critical metabolism-related hormones, adiponectin and leptin (adipokines, over childhood.Plasma adiponectin and leptin were measured in 80 Mexican-American children at birth and again at 2, 5, and 9 years from the ongoing prospective cohort followed by the Center for the Health Assessment of Mothers and Children of Salinas (CHAMACOS. We used a mixture modeling approach to identify patterns in adipokine trajectories from birth to 9 years.Leptin was positively related to child body size within all ages, however adiponectin had inverse and weaker associations with BMI at 2, 5, and 9 years. Correlations between adipokine levels over the 0-2, 2-5, and 5-9-year periods increased for both leptin (r = 0.06, 0.31 and 0.62 and adiponectin (r = 0.25, 0.41 and 0.46. Our mixture modeling approach identified three trajectory clusters for both leptin (1L [slowly-rising], 2L [rapidly-rising], and 3L [stable] and adiponectin (1A [steep-dropping and rebounding], 2A [moderately-dropping], and 3A [stable]. While leptin groups were most separated over the 2-9-year period, adiponectin trajectories displayed greatest heterogeneity from birth to 2 years. Children in the rapidly-rising 2L group had highest BMI and waist circumference at 9 years. Further, children with greater birth weight had increased odds of belonging to this high risk group (OR = 1.21 95% CI 1.03, 1.43, compared to stable group 3L. Children whose mothers consumed more sugar-sweetened beverages during pregnancy were at risk of being in the steep-dropping 1A group (OR = 1.08, 95% CI 1.01, 1.17, compared to stable group 3A.Our results highlight developmental differences in leptin and adiponectin over the childhood period. Leptin closely reflects child body size however factors affecting adiponectin and long-term consequences of its changes over infancy need to be further explored.

    Mexican-heritage youth living along the U.S.-Mexico border have higher rates of obesity than non-Hispanic Whites. Parenting strategies may influence youth physical activity (PA) and sedentary behaviors (SB) mitigating these obesity rates; however, parenting strategies have not been well examined in Hispanic cultures. Therefore, we examined relationships between parenting strategies and PA and SB of Mexican-heritage youth. Mother-child dyads (n = 121 dyads) were surveyed during the summer and school-year. Quantile regression estimated relationships between parenting strategies, and PA and SB. Summer. Reinforcement was negatively associated with moderate-to-vigorous PA (MVPA) among more active youth (β = -364.4); limit setting was negatively associated with SB among less sedentary youth (β = -23.3); and use of discipline was negatively associated with sedentary screen time in youth reporting less screen use (β = -3.2). School-year. Males reported more MVPA (773.9 min/week) than females (738.7 min/week). Reinforcement was positively associated with weekly MVPA among more active youth (β = 173.6), fewer sedentary minutes/week among all youth, and fewer sedentary screen time minutes among less sedentary youth (β = -6.4). Parenting strategies are related with PA and SB. Investigators should focus on identifying modifiable parenting strategies to address the various needs presented during summertime and school-year for Mexican-heritage youth.

    Full Text Available Objective. To estimate the HIV seroprevalence among Mexicans aged 15 to 49 years old and living in households, and to describe the profile of serorreactive individuals. Materials and methods. Cross-sectional study with a national probabilistic sample of individuals aged 15 to 49 years with behavioral data from direct interview (face-to-face at households and HIV screening using capillary blood collected from the same individuals. Results. A seroprevalence of 0.15% (95%CI 0.09-0.21 was estimated for Mexicans aged 15 to 49; seroprevalence among women was 0.07% (95%CI 0.03-0.11 and 0.24% (95%CI 0.11-0.36 for men. HIV serorreactive population is composed of younger men, with a higher socioeconomic level compared to the general population, and with a higher insurance coverage –social protection on health in general and social security in particular. Only 50% of the serorreactive individuals may be aware of their status as living with HIV. Conclusions. The estimated HIV seroprevalence in the NHNS 2012 suggests a stable pattern since 2000. The estimated prevalence among individuals 15 to 49 years was adjusted both for selection bias correction and to include MSM estimations (under the assumption that MSM is a population hard to reach in a household survey, resulting in a total seroprevalence of 0.23% and an estimated number of people with HIV of 140000

    The purpose of this study was to compare severity and risk status for anxiety and depression with coping skills among 130 Mexican school children with learning disabilities (LD) and 130 school children without LD. This research is the first to explore the emotional difficulties of Mexican children with LD. Children completed the Spanish version of the Spence Children's Anxiety Scale and Children's Depression Inventory, and the Cuestionario de Afrontamiento (Coping Skills Questionnaire). Results indicated that a higher percentage of children with LD were at risk for anxiety (22.3% vs. 11.5%) and depression (32% vs. 18%). No statistically significant differences were found for coping skills. Results support the idea that there is an increased awareness of comorbid depression and anxiety among students with LD and a need to promote early identification and intervention in schools. Efforts should focus on better understanding the relationship between social-emotional difficulties and academic achievement and on developing effective interventions to support children with LD.

  12. Associations between language acculturation, age of immigration, and obesity in the Mexican American Mano A Mano cohort.

    Chrisman, Matthew; Chow, Wong-Ho; Daniel, Carrie R; Wu, Xifeng; Zhao, Hua

    As Mexican immigrants to the U.S. become acculturated, they face worsening health outcomes such as obesity. The role of language acculturation in the development of obesity has not been thoroughly examined. To examine associations between language acculturation and obesity, data were drawn from the Mexican-American Mano A Mano cohort study. Participants aged 20 years and over (n=18,298) completed baseline questionnaires on socio-demographic and behavioural factors, including physical activity and sitting time. The Bi-dimensional Acculturation Scale for Hispanics assessed language acculturation. Multivariate-adjusted logistic regression was conducted to investigate associations between language acculturation, immigration age, and obesity, and whether sitting time and physical activity mediated these associations. Individuals with obesity were more linguistically acculturated than individuals who were normal weight or overweight (P<0.001); however, this relationship differed by gender and nativity. Among Mexico-born women, language acculturation score was inversely related to BMI (P<0.001). Language acculturation was associated with higher risk of obesity (OR=1.35, 95% CI: 1.12-1.62) in U.S.-born participants and lower risk in Mexico-born participants (OR=0.90, 95%CI=0.81-1.00). For Mexico-born participants, arrival in the U.S. as an adult (≥20years old) was associated with a reduced obesity risk (OR=0.74, 95% CI: 0.67-0.80). Sitting time mediated the association between language acculturation and obesity. Language acculturation may influence obesity development among the U.S.-born Mexican Americans in this cohort, but not their Mexico-born counterparts. Sitting time could be targeted in obesity prevention efforts in this population. Copyright © 2017 Asia Oceania Association for the Study of Obesity. Published by Elsevier Ltd. All rights reserved.

    This study examined differences in behavioral autonomy age expectations between Mexican-origin mothers and their adolescent daughters (N = 319 dyads); variability in behavioral autonomy age expectations as a function of nativity and maternal educational attainment also was examined. Findings indicated significant differences between mothers and daughters such that mothers reported later expectations for the timing of behavioral autonomy than did daughters. Follow-up analyses indicated that findings appeared to be driven by maternal nativity, with dyads comprised of Mexico-born mothers reporting the latest age expectations for behavioral autonomy when compared with dyads comprised of U.S.-born mothers. Findings underscore the need to examine normative development among Latino adolescents and their families with a specific focus on how sociocultural characteristics can contribute to within-family differences.

    Arthritis and vitamin D insufficiency are prevalent in older adults and are risk factors for disability. The objective of this study was to examine the effect of co-occurring arthritis and vitamin D deficiency on upper-lower extremity functional limitations and disability in older adults. We examined 1533 participants aged ≥50 years from a subsample of the Mexican Health and Aging Study. Measures included sociodemographics, body mass index, comorbid conditions, falls, physical activity, physical function tests, functional limitations, activities of daily living (ADL), and vitamin D. Participants were categorized into four groups according to arthritis and vitamin D status: no vitamin D insufficiency and no arthritis (58.80%), vitamin D insufficiency only (27.49%), arthritis only (8.47%), and arthritis and vitamin D insufficiency (5.24%). Fourteen percent reported arthritis, and 31.2% had vitamin D insufficiency. The arthritis and vitamin D insufficiency group was associated with upper-lower extremity functional limitations [odds ratio (OR) 1.82, 95% confidence interval (CI) 1.06-3.15, and OR 1.90, 95% CI 1.00-3.62, respectively] and ADL disability (OR 3.00, 95% CI 1.63-5.51) when compared with the no vitamin D insufficiency and no arthritis group (reference group). The arthritis only group was three times more likely to report upper-lower extremity functional limitations and ADL disability. The vitamin D insufficiency only group was not significantly associated with functional limitations nor ADL disability. Arthritis and vitamin D insufficiency increased the risk of ADL disability in this population. However, the effect of arthritis and vitamin D insufficiency on upper-lower extremity functional limitations was not higher than the effect of arthritis only, but higher than the effect on vitamin D insufficiency alone.

    To determine the age of immigration at which the marked increase in risk for alcohol- and drug-use problems in adulthood is observed among Mexican American adults residing in 2 distinct contexts: the U.S.-Mexico border, and cities not proximal to the border. We used 2 samples of Mexican American adults: specifically, 1,307 who resided along the U.S.-Mexico border, and 1,288 non-border adults who were interviewed as a part of the 2006 Hispanic Americans Baseline Alcohol Survey study. Survey logistic and Poisson regression methods were used to examine how immigration age during adolescence is related to alcohol- and drug-use behavior in adulthood. We found that participants who immigrate to the United States prior to age 14 have qualitatively different alcohol- and drug-related outcomes compared to those who immigrate later in life. Adults who immigrated at younger ages have alcohol- and drug-use patterns similar to those who were U.S.-born. Adults who immigrated at young ages and reside distal from the U.S.-Mexico border are at greater risk for alcohol and drug use than those who live in border contexts. Immigration from Mexico to the U.S. before age 14 results in alcohol- and drug-related behavior that mirrors the behavior of U.S.-born residents, and the alcohol- and drug-use effects were more pronounced among adults who did not reside proximal to the U.S.-Mexico border.

    Curiosity motivated consumption of illegal drugs by young people decreased during the last 5 years. At the same time the problem of school-children abusing alcohol increased. This has to be seen against the background of more general epidemiological data of alcohol consumption in the Federal Republic of Germany: --between 1961 and 1974 the expenditure for alcoholic beverages more than doubled; --according to serious estimations there are between 700,000 and 1 million of alcoholics in this country (from these about 8-10% being minors); --the average age of inmates of clinics for alcoholics dropped considerably during the last decade. Main findings of a follow-up survey conducted (size of sample: about 10,000 school-children in Hamburg, age 13-20, representative of a total of 110,000) are: --more than 25% of the above mentioned 110,000 school-children showed a rather excessive drinking behaviour (i.e. having been drunk 1-5 or more than 5 times during a period of 2 months prior to the interviews); --positive correlations were found to exist between excessive drinking habits and certain psycho-social variables (i.e. broken home, suicide-attempts, excessive consumption of alcohol by the parents, etc.); --the subgroup of those school-children who were users of illegal drugs: about 60% of them belong also to the category of "excessive alcohol user". Reasons for the general increase of alcohol consumption in Western Germany are for instance: --a change of drinking habits (more frequently, drinking at home and alone); --a shift of preferances (from relatively low percentage-beverages like beer and wine to so-called hard liquors); --an increase of alcohol consumption among those societal groups--the young and women--who formerly were almost abstinent. Some reasons and causes for the increase of alcohol consumption among school-children are: --being exposed to negative model-behaviour of adults and especially of parents; --peer-group pressure; --the discovery of school

    Little is known about the dietary behaviors of Mexican children with regard to frequency, amount, and quality of foods consumed at eating occasions and their impact on total daily energy intake. The objectives were to 1) describe foods consumed across eating occasions and 2) examine whether the number or type of total eating occasions was associated with increased total daily energy intake and differed between 2- to 5-y-old and 6- to 13-y-old Mexican children. A nationally representative sample of 5031 children from the 2012 ENSANUT (Encuesta Nacional de Salud y Nutrición) was used to examine the percentage of meals and snacks consumed, mean energy intake from meals and snacks, and the top food groups contributing to meals and snacks. Multivariate linear regression was used to examine the association between meals, snacks, and total eating occasions with daily energy intake for 2- to 5-y-old and 6- to 13-y-old children. Eating patterns were similar across age groups (per capita mean intake of 3 meals and 1.4-1.6 snacks/d). Each additional snack was associated with greater increases in mean daily energy for older children (+191-289 kcal/d; P eating occasion was associated with greater increases in mean daily energy for older children (+323 kcal/d; P eating occasion was linked to even greater increases in total daily energy intake. © 2015 American Society for Nutrition.

  1. A case study of the effects of social experiences on the science identity formation of Mexican American females in high school chemistry

    Beeton, Renee P.

    Mexican Americans are a rapidly growing ethnic group in the United States. However, they are noticeably absent from physical science fields. Little research has explored the experiences of Mexican American girls in high school chemistry. The theories of identity based on communities of practice and multicultural feminism framed this year-long case study of nine Mexican American girls in a high school chemistry course. This study explored the social encounters and experiences that shaped the participants' identities and how their views of themselves affected their attitudes towards high school chemistry and future science careers. Data collection included a focus group and in-depth interviews with the participants, classroom observations, and teacher interviews. Five main identities influenced the participants' potential to become a scientist: ethnic, gender, science, student, and college. Mexican ethnic identity was the overarching identity; however gender also influenced the participants' other identities. The participants were aware of ethnic gender stereotypes that might hinder them from being successful in science. Also, ethnic factors, such as citizenship and abilities to receive financial aid limited their views of themselves as chemists. Participatory science, student, and school identities were all needed in order for the participants to be potential scientists. Family expectations, authentic relationships with teachers, and personal connections were important factors in the development of these participatory identities.

    This article discusses the issue of assent of school-age bilingual children to participate in a research study. The article reviews cognitive, cultural, and linguistic factors influencing verbal and nonverbal concept formation in bilingual children. At the applied level, the focus of the article is on methodological considerations in using this information to obtain assent from a child who is bilingual and speaks English as a second language. Recommendations for the assessment of the child's language dominance, language proficiency, and the development of the assent form are provided. Language diversity and its potential effects on the assent process need to be formally acknowledged and appropriately addressed.

    Ballmer-Weber, B

    2012-04-01

    In young children food allergy is mainly acquired over the gastrointestinal tract and directed to egg and milk. Patients at school age or adult patients, however, often acquire a food allergy over a primary sensitisation to inhalant allergens, in Switzerland primarily over birch pollen. This type of food allergy is directed to plant foods. Apple and hazelnut are the most prevalent allergenic foods in this age group. A birch pollen related food allergy is often accompanied by mild allergic symptoms such as the oral contact urticaria. The relevant allergens are labile to heat and are often tolerated in heat processed form. Severe up to anaphylactic symptoms, however, have been reported in birch pollen related soy allergy. Physical exercise, intake of alcohol, NSAIDs, betablocking agents or eventually antacids may aggravate the severity of a food allergic reaction.

    Mexico faces malnutrition problems in the child population. Analysis of food consumption in small children allows us to identify and propose strategies focused on feeding to improve their nutritional status. We described the consumption of beverages and food groups in Mexican children Health and Nutrition Study). Dietary information was obtained through 24-h recalls. The foods and beverages consumed were divided into 17 groups. Consumption was estimated in grams or milliliters, kilocalories per day, and percentage of energy (PE) per day. The percentage of consumers was calculated for each food group and stratified by age (<6, 6-11, and 12-23 mo) and by breastfeeding status (breastfed or not breastfed). Differences in the consumption of food groups were analyzed by breastfeeding status, area of residence (urban or rural), and socioeconomic status (SES) by using linear regression adjusted for age, breastfeeding status, and survey design. Only 35% of the children consumed breast milk. Infant formula was consumed by 48% in children aged <6 mo and by 33% in children 6-11 mo old. More than 35% of the children aged 6-11 and 12-23 mo and 12% of children <6 mo old consumed nondairy sugar-sweetened beverages. Legumes and seeds and maize-based preparations contributed a higher PE in rural areas (3.4% and 1.9%, respectively) than in urban areas (11.1% and 6.4%, respectively) (P < 0.05). Children from the lowest SES category consumed less PE from cereals other than maize (2.4%) and more from maize-based preparations (10.2%) than did the middle (4.9% from other cereals and 8.0% from maize) and high (6.0% from other cereals and 4.5% from maize) SES categories (P < 0.05). Mexican children <24 mo of age do not consume a diet that meets recommendations, which is consistent with the high prevalence of malnutrition in Mexico. © 2016 American Society for Nutrition.

    A national health objective is to reduce average U.S. sodium intake to 2,300 mg daily to help prevent high blood pressure, a major cause of heart disease and stroke. Identifying common contributors to sodium intake among children can help reduction efforts. Average sodium intake, sodium consumed per calorie, and proportions of sodium from food categories, place obtained, and eating occasion were estimated among 2,266 school-aged (6–18 years) participants in What We Eat in America, the dietary intake component of the National Health and Nutrition Examination Survey, 2009–2010. U.S. school-aged children consumed an estimated 3,279 mg of sodium daily with the highest total intake (3,672 mg/d) and intake per 1,000 kcal (1,681 mg) among high school–aged children. Forty-three percent of sodium came from 10 food categories: pizza, bread and rolls, cold cuts/cured meats, savory snacks, sandwiches, cheese, chicken patties/nuggets/tenders, pasta mixed dishes, Mexican mixed dishes, and soups. Sixty-five percent of sodium intake came from store foods, 13% from fast food/pizza restaurants, 5% from other restaurants, and 9% from school cafeteria foods. Among children aged 14–18 years, 16% of total sodium intake came from fast food/pizza restaurants versus 11% among those aged 6–10 years or 11–13 years (pschool meal on the day assessed, 26% of sodium intake came from school cafeteria foods. Thirty-nine percent of sodium was consumed at dinner, followed by lunch (29%), snacks (16%), and breakfast (15%). Sodium intake among school-aged children is much higher than recommended. Multiple food categories, venues, meals, and snacks contribute to sodium intake among school-aged children supporting the importance of populationwide strategies to reduce sodium intake. New national nutrition standards are projected to reduce the sodium content of school meals by approximately 25%–50% by 2022. Based on this analysis, if there is no replacement from other sources, sodium intake

    Purpose Understanding how the convergence between chronic and complex diseases—such as cancer—and emerging conditions of older adults—such as frailty—takes place would help in halting the path that leads to disability in this age group. The objective of this manuscript is to describe the association between a past medical history of cancer and frailty in Mexican older adults. Methods This is a nested in cohort case-control study of the Mexican Health and Aging Study. Frailty was categorized by developing a 55-item frailty index that was also used to define cases in two ways: incident frailty (incident >0.25 frailty index score) and worsening frailty (negative residuals from a regression between 2001 and 2012 frailty index scores). Exposition was defined as self-report of cancer between 2001 and 2012. Older adults with a cancer history were further divided into recently diagnosed (10 years from the initial diagnosis). Odds ratios were estimated by fitting a logistic regression adjusted for confounding variables. Results Out of a total of 8022 older adults with a mean age of 70.6 years, the prevalence of a past medical history of cancer was 3.6 % (n = 288). Among these participants, 45.1 % had been diagnosed with cancer more than 10 years previously. A higher risk of incident frailty compared to controls [odds ratio (OR) 1.53 (95 % confidence interval (CI) 1.04–2.26, p = 0.03); adjusted model OR 1.74 (95 % CI 1.15–2.61, p = 0.008)] was found in the group with a recent cancer diagnosis. Also, an inverse association between a remote cancer diagnosis and worsening frailty was found [OR = 0.56 (95 % CI 0.39–0.8), p = 0.002; adjusted model OR 0.61 (95 % CI 0.38–0.99, p = 0.046)]. Conclusions Cancer is associated with a higher frailty index, with a potential relevant role of the time that has elapsed since the cancer diagnosis. Implications for cancer survivors Cancer survivors may be more likely to develop frailty or worsening of the health status at an

    While overweight and obese children are more likely to have overweight or obese parents, less is known about the effect of parental weight status on children's success in weight management programmes. This study was a secondary data analysis of a randomized controlled trial and investigated the impact of having zero, one or two obese parents on children's success in a school-based weight management programme. Sixty-one Mexican-American children participated in a 24-week school-based weight management intervention which took place in 2005-2006. Children's heights and weights were measured at baseline, 3, 6 and 12 months. Parental weight status was assessed at baseline. Repeated measures anova and ancova were conducted to compare changes in children's weight within and between groups, respectively. Within-group comparisons revealed that the intervention led to significant decreases in standardized body mass index (zBMI) for children with zero (F = 23.16, P school-based weight management programme appears to be most efficacious for children with one or no obese parents compared to children with two obese parents. These results demonstrate the need to consider parental weight status when engaging in childhood weight management efforts. © 2015 World Obesity.

    Traditional methods of aging adult skeletons suffer from the problem of age mimicry of the reference collection, as described by Bocquet-Appel and Masset (1982). Transition analysis (Boldsen et al., 2002) is a method of aging adult skeletons that addresses the problem of age mimicry of the reference collection by allowing users to select an appropriate prior probability. In order to evaluate whether transition analysis results in significantly different age estimates for adults, the method was applied to skeletal collections from Postclassic Cholula and Contact-Period Xochimilco. The resulting age-at-death distributions were then compared with age-at-death distributions for the two populations constructed using traditional aging methods. Although the traditional aging methods result in age-at-death distributions with high young adult mortality and few individuals living past the age of 50, the age-at-death distributions constructed using transition analysis indicate that most individuals who lived into adulthood lived past the age of 50.

    Full Text Available Background. The prevalence of dysphonia in schoolchildren has been reported to be from 7.1% to 23.3% and in adolescents from 0 to 80%. In Slovenia, the study on prevalence of dysphonia in schoolchildren has not been performed yet.Methods. The voice samples of 100 4th-graders and 102 8thgraders of elementary school were recorded. A lay judge and a professional assessed independently degree of hoarseness in the voice samples. One to three months after the recording, the dysphonic children were invited to an otorhinolaryngologic examination in order to find out the cause of dysphonia. All children and their parents answered the questionnaires on illnesses and vocal habits that might cause hoarseness. The prevalence of these unfavourable factors was compared between the group of children with long lasting hoarseness and the children without it.Results. At voice samples’ recording there were 34.2% dysphonic children. One to three months later, there were still 14.9% children with hoarse voice. The most frequent causes for acute dysphonia were acute respiratory infection and exacerbation of chronic laryngitis. The most frequent causes for persistent dysphonia were allergic catarrhal laryngitis, muscle tension dysphonia with or without vocal nodules and mutational voice disorder. The fast speaking rate appeared to be characteristic for children with long lasting dysphonia.Conclusions. Dysphonia in school-age children is the result of diseases of upper respiratory tract and/or functional voice disorders. Both causes of dysphonia could be successfully treated if they are detected early and the children are advised to see an otorhinolaryngologist. Adolescence is an ideal period for treatment of functional voice disorders. It is also the period when the children must decide for their future profession.

    Full Text Available Aim. To evaluate the ability of five clinimetric instruments to discriminate between subjects >60 years of age living at home versus those living in a residency.Methods. Trained nutritionists applied five instruments (Cognition/ Depression/ Functionality/ Nutrition/ Appetite to 285 subjects with majorities of women (64%, aged <80y (61% and home residents (54%.Results. Multivariable regression models were generated for each instrument using age, gender and residency as independent variables. Age was associated with worsening scores in the five instruments whereas residency showed association in three instruments, and gender in two. Score-age regressions by place of residency showed differences suggesting that Mundet residents had increasingly worse scores with increasing age, than home dwellers for Cognition, Depression and Nutrition. Also, living at home prevented the worsening of Depression with increasing age. In contrast, Functionality and Appetite deteriorated at a similar rate for home and Mundet residents suggesting an inhability of these two instruments to dicriminate between settings. Score-age regressions by gender suggested males have less cognitive problems at 60 and 80 years of age but not at 100, and better appetite than women at all ages.Conclusions. Increasing age proved to be associated to worsening scores in the five instruments but only three were able to detect differences according to setting. An interesting observation was that living at home appeared to prevent the Depression increase with increasing age seen in Mundet residents.

    Objective Diabetes has been growing as a major health problem and a significant burden on the population and on health systems of developing countries like Mexico that are also ageing fast. The goal of the study was to estimate the future prevalence of diabetes among Mexico’s older adults to assess the current and future health and economic burden of diabetes. Design A simulation study using longitudinal data from three waves (2001, 2003 and 2012) of the Mexican Health and Aging Study and adapting the Future Elderly Model to simulate four scenarios of hypothetical interventions that would reduce diabetes incidence and to project the future diabetes prevalence rates among populations 50 years and older. Participants Data from 14 662 participants with information on self-reported diabetes, demographic characteristics, health and mortality. Outcome measures We obtained, for each scenario of diabetes incidence reduction, the following summary measures for the population aged 50 and older from 2012 to 2050: prevalence of diabetes, total population with diabetes, number of medical visits. Results In 2012, there were approximately 20.7 million persons aged 50 and older in Mexico; 19.3% had been diagnosed with diabetes and the 2001–2003 diabetes incidence was 4.3%. The no-intervention scenario shows that the prevalence of diabetes is projected to increase from 19.3% in 2012 to 34.0% in 2050. Under the 30% incidence reduction scenario, the prevalence of diabetes will be 28.6% in 2050. Comparing the no-intervention scenario with the 30% and 60% diabetes incidence reduction scenarios, we estimate a total of 816 320 and 1.6 million annual averted cases of diabetes, respectively, for the year 2020. Discussion Our study underscores the importance of diabetes as a disease by itself and also the potential healthcare demands and social burden of this disease and the need for policy interventions to reduce diabetes prevalence.

    Full Text Available This article focuses on Mexican students’ perceptions of learning the history of Mexico in English through content-based instruction, which is one of many types of bilingual pedagogical approaches that are now considered established approaches in Mexico and around the globe. A phenomenological approach was chosen in order to understand and examine participants’ lived experiences through semi-structured interviews; this in turn led to the discovery of their acceptance or rejection towards learning the history of Mexico in English. The data suggest that despite students’ initial rejection to learning a sensitive subject as is the history of Mexico in English, most students found the content-based method as being meaningful, thus, they had a sense of pride in the end.

    Full Text Available Overweight children and childhood obesity are a public health problem in Mexico. Obesity is traditionally assessed using body mass index (BMI, but an excess of adiposity does not necessarily reflect a high BMI. Thus, body composition indexes are a better alternative. Our objective was to generate body composition percentile curves in children from Mexico City. A total of 2026 boys and 1488 girls aged 6 to 12 years old were studied in Mexico City. Body weight, height, and BMI calculation were measured. Total body fat percentage (TBFP was derived from the skinfold thicknesses, and fat mass (FMI and free fat mass indexes (FFMI were calculated. Finally, age- and gender-specifıc smoothed percentile curves were generated with Cole’s Lambda, Mu, and Sigma (LMS method. In general, height, weight, waist circumference (WC, and TBFP were higher in boys, but FFM was higher in girls. TBFP appeared to increase significantly between ages 8 and 9 in boys (+2.9% and between ages 10 and 11 in girls (+1.2%. In contrast, FFM% decreased noticeably between ages 8 and 9 until 12 years old in boys and girls. FMI values peaked in boys at age 12 (P97 = 14.1 kg/m2 and in girls at age 11 (P97 = 8.8 kg/m2. FFMI percentiles increase at a steady state reaching a peak at age 12 in boys and girls. Smoothed body composition percentiles showed a different pattern in boys and girls. The use of TBFP, FMI, and FFMI along with BMI provides valuable information in epidemiological, nutritional, and clinical research.

    To determine the prevalence of edentulism in adults aged 18 years and older in Mexico and to describe its distribution in 20 of the 32 States in Mexico, highlighting the experience in the WHO age groups. A secondary analysis of the National Performance Evaluation Survey 2002-2003 (representative at the state level and part of the Word Health Survey) was undertaken. The sample design was probabilistic, stratified and through conglomerates. Data on dental conditions were available only for 20 of the 32 states of Mexico, leading to a total of 24 159 households (N = 54 638 654). The percentage of edentulism was determined as the proportion of subjects that self-reported complete loss of teeth. Data were analyzed using the SVY module for complex surveys in STATA 8.2. The mean age was 41.3 +/- 17.0 years (range 18-99). An estimated 6.3% (N = 3 437 816) of the population > or =18 years was edentulous. Lowest prevalences were observed in the states of Tlaxcala, Puebla and the Estado de Mexico with 3.4%, 3.8% and 4.5%, respectively. Highest prevalences were observed in San Luis Potosí, Colima, and Michoacán with 10.3%, 10.2% and 10.1%, respectively. Following the WHO age groups, the prevalence ranged from 2.4% in the 35-44 group through 25.5% in the 65-74 group. No obvious association between socio-economic and socio-demographic indicators at the state level and prevalence of edentulism was found. The prevalence of complete tooth loss observed in the present study varied greatly across states, although no straightforward association was found with socio-economic and socio-demographic indicators at the state level. This study could serve as a baseline to enable future evaluations of the oral status of Mexican adults and elders, following WHO age groups.

    Vitamin D deficiency was common in older adults from a country with adequate sun exposure. The variables associated with this deficiency provide insight into the next steps needed to characterize older adults with this deficiency and to treat it accordingly. The aim of this study was to describe the prevalence of and factors associated with vitamin D deficiency among Mexican older adults. This was a secondary analysis of the last wave of the Mexican Health and Aging Study. Vitamin D levels along with other biomarkers were obtained from a sub-sample of Mexican adults older than 60 years. Prevalence was described by sex and age group, and a multivariate analysis was performed to test the factors associated with this condition. Data from 1088 adults over the age of 60 years were analyzed. The mean serum vitamin D level was 23.1 ± 8.1 ng/mL and was significantly higher among men than women (25.6 ± 0.6 and 22.8 ± 0.5 ng/mL, respectively; p vitamin D deficiency, 65% of whom were women. Low 25-(OH)-vitamin D levels were associated with female sex (OR 1.74, 95% CI 1.59-2.42), current smoking (OR 2.21, 95% CI 1.47-3.39), education (OR 1.1, 95% CI 1.06-1.13), physical activity (OR 1.74, 95% CI 1.31-2.23), and high levels of glycated hemoglobin (OR 1.16, 95% CI 1.07-1.25). Vitamin D deficiency was highly prevalent in Mexican older adults and was associated with a number of factors, indicating the multifactorial causality of this deficiency.

    Migrant and seasonal farmworkers are at high risk for musculoskeletal and other occupational injuries. Although persons aged 40-80 years account for 40 % of all US farmworkers and as many as 50 % in certain regions, little is known about their occupational health issues. The current study examined work-related persistent musculoskeletal injuries (PMIs) and their association with clinical and functional indicators of disability and health-related quality of life (HRQOL) in 177 middle-aged and elderly US-Mexico border farmworkers. At interview, 68 % reported current PMI pain; 51 % had pain at multiple sites. PMI pain was associated with increased shoulder, knee, and lower extremity dysfunction and reduced HRQOL scores. However, fewer than 25 % of injured participants received any conventional medical treatment. The study results indicated that work-related PMIs, especially multiple PMIs, caused significant functional impairment, disability, and poorer HRQOL, adversely affecting the ability of the aging farmworkers to perform work, self-care, and other daily activities.

    Corruption pervades educational and other institutions worldwide and medical schools are not exempt. Empirical evidence about levels and types of corruption in medical schools is sparse. We conducted surveys in 2000 and 2007 in the medical school of the Autonomous University of Guerrero in Mexico to document student perceptions and experience of corruption and to support the medical school to take actions to tackle corruption. In both 2000 and 2007 medical students completed a self-administered questionnaire in the classroom without the teacher present. The questionnaire asked about unofficial payments for admission to medical school, for passing an examination and for administrative procedures. We examined factors related to the experience of corruption in multivariate analysis. Focus groups of students discussed the quantitative findings. In 2000, 6% of 725 responding students had paid unofficially to obtain entry into the medical school; this proportion fell to 1.6% of the 436 respondents in 2007. In 2000, 15% of students reported having paid a bribe to pass an examination, not significantly different from the 18% who reported this in 2007. In 2007, students were significantly more likely to have bribed a teacher to pass an examination if they were in the fourth year, if they had been subjected to sexual harassment or political pressure, and if they had been in the university for five years or more. Students resented the need to make unofficial payments and suggested tackling the problem by disciplining corrupt teachers. The university administration made several changes to the system of admissions and examinations in the medical school, based on the findings of the 2000 survey. The fall in the rate of bribery to enter the medical school was probably the result of the new admissions system instituted after the first survey. Further actions will be necessary to tackle the continuing presence of bribery to pass examinations and for administrative procedures. The

Students resented the need to make unofficial payments and suggested tackling the problem by disciplining corrupt teachers. The university administration made several changes to the system of admissions and examinations in the medical school, based on the findings of the 2000 survey. Conclusion The fall in the rate of bribery to enter the medical school was probably the result of the new admissions system instituted after the first survey. Further actions will be necessary to tackle the continuing presence of

    Although the relationship between health behaviors and outcomes such as smoking and obesity with longer residence in the United States among Mexican American immigrants is established, the relationship between length of residency in the United States and risk for cardiovascular disease (CVD) is not fully understood. The objective of this study was to determine the relationship between immigrant status, length of residence in the United States, age, and CVD markers in a sample of Mexican American adults living in Brownsville, Texas. We categorized participants in the Cameron County Hispanic Cohort study as immigrants in the United States for 10 years or less, immigrants in the United States for more than 10 years, or born in the United States. We conducted logistic and ordinary least squares regression for self-reported chronic conditions and CVD biomarkers. We found bivariate differences in the prevalence of self-reported conditions and 1 CVD biomarker (low-density lipoprotein cholesterol) by length of residence in the middle (41-64 y) and younger (18-40 y) age groups. After adjusting for covariates, the following varied significantly by immigrant status: stroke and high cholesterol (self-reported conditions) and diastolic blood pressure, systolic blood pressure, total cholesterol, and low-density lipoprotein cholesterol (CVD biomarkers). The association between immigrant status, length of residence in the United States, and CVD markers varied. The effect of length of residence in the United States or immigrant status may depend on age and may be most influential in middle or older age.

    Full Text Available This study was made from a random sample of students of secondary school (basic education, in urban an rural schools of the public sector of the state of Michoacán, Mexico. Significant cognitive changes of basic concepts of Ecology, during the whole academic year were assessed in each one of the three grades which conform this level of education. For such purpose, a group of six fundamental and four complementary concepts was used with which a core concept diagram was elaborated. From this diagram, a 23 task questionnaire was designed and applied as conceptual assessment instrument. The general results show that there are no significant differences, statistically speaking, between the beginning and the end of the academic year, regarding the principal Ecology concepts and other related concepts that were assessed as well. This study included an interpretative phase based in conceptual maps, which results are not included in this article.

    This study aimed to determine the frequency of Entamoeba histolytica and Entamoeba dispar infection in school children in the community of Tlaltizapan, in order to understand the dynamics of infection within the school and family spheres of this population. Amoebiasis is an unsolved public health problem and an endemic disease in Mexico. The incidence rate varies depending on the state; the most affected states show the highest numbers of new cases of amoebiasis per year. Previously, we reported the molecular frequency of infection with E. histolytica and/or E. dispar in other rural communities of the state of Morelos. Children from 3 schools were studied to estimate the frequency of intestinal parasites through microscopic examination of fresh stool samples. The number of studied individuals were 309 school children. The molecular characterization of E. histolytica or E. dispar was carried out by Polymerase Chain Reaction (PCR) using species-specific primers to amplify short tandem repeats (STR) in non-coding sequences associated with the tRNA gene; the amplified fragments were sequenced and analyzed. Eight different genotypes were obtained from E. dispar isolates with the molecular marker NKD3-D5. None of the cases in which the species E. histolytica was detected developed symptoms attributable to an invasive process of disease. Moreover, the parasitized condition appeared to have no significant impact on the development or nutritional status of affected children. Genotype 1, which corresponds to the reference strain E. dispar SAW760, considered a non-pathogenic amoeba, was the most prevalent. The comparison of the genotypes of Entamoeba species did not show a correlation between children and their relatives. In this community, the species Entamoeba dispar genotype 1 was the most widespread. Based on the indicators of growth, development and nutrition status, the studied community seems to be reasonably adapted to constant exposure to intestinal parasites, since

  20. Age at menarche, schooling, and sexual debut in northern Malawi.

    Directory of Open Access Journals (Sweden)

    Judith R Glynn

    Full Text Available BACKGROUND: Age at sexual debut is a key behavioural indicator used in HIV behavioural surveillance. Early age at menarche may precipitate early sex through perceived readiness for sex, or through school drop-out, but this is rarely studied. We investigated trends and circumstances of sexual debut in relation to schooling and age at menarche. METHODS AND FINDINGS: A cross-sectional sexual behaviour survey was conducted on all individuals age 15-59 within a demographic surveillance site in Karonga District, Malawi. Time trends were assessed using birth cohorts. Survival analysis was used to estimate the median age at menarche, sexual debut and first marriage. The 25(th centile was used to define "early" sex, and analyses of risk factors for early sex were restricted to those who had reached that age, and were done using logistic regression. Of the 8232 women and 7338 men resident in the area, 88% and 78%, respectively, were seen, and, 94% and 92% of these were interviewed. The median reported age at first sex was 17.5 for women and 18.8 for men. For women, ages at menarche, sexual debut and first marriage did not differ by birth cohort. For men, age at sexual debut and first marriage decreased slightly in later birth cohorts. For both men and women increased schooling was associated with later sexual debut and a longer delay between sexual debut and first marriage, but the associations were stronger for women. Earlier age at menarche was strongly associated with earlier sexual debut and marriage and lower schooling levels. In women early sexual debut (<16 years was less likely in those with menarche at age 14-15 (odds ratio (OR 0.31, 95%CI 0.26-0.36, and ≥16 (OR 0.04, 95%CI 0.02-0.05 compared to those with menarche at <14. The proportion of women who completed primary school was 46% in those with menarche at <14, 60% in those with menarche at 14-15 and 70% in those with menarche at ≥16.

    Full Text Available BACKGROUND: Active transport is a very important factor for increasing the level of physical activity in children, which is significant for both their health and positive physical behaviour in adult age. OBJECTIVE: The aim of the study was to establish the proportion of Czech children aged 11 to 15 who select active transport to and from school and, at the same time, describe socio-economic and socio-demographic factors influencing active transport to and from school among children. METHODS: To establish the socio-demographic factors affecting active transport, data of a national representative sample of 11 to 15 year-old elementary school children in the Czech Republic (n = 4,425. Research data collection was performed within an international research study called Health Behaviour in School Aged Children in June 2010. Statistical processing of the results was made using a logistic regression analysis in the statistical programme IBM SPSS v 20. RESULTS: Active transport to and from school is opted for in the Czech Republic by approximately 2/3 of children aged 11 to 15. Differences between genders are not statistically significant; most children opting for active transport are aged 11 (69%. An important factor increasing the probability of active transport as much as 16 times is whether a child's place of residence is in the same municipality as the school. Other factors influencing this choice include BMI, time spent using a computer or a privateroom in a family. A significant factor determining active transport by children is safety; safe road crossing, opportunity to leave a bicycle safely at school, no fear of being assaulted on the way or provision of school lockers where children can leave their items. CONCLUSIONS: Active transport plays an important role in increasing the overall level of physical activity in children. Promotion of active transport should focus on children who spend more time using a computer; attention should also be

    Physical activity is an important component of strategies for health promotion and prevention of noncommunicable diseases. It is also associated with decreased risk for cardiovascular disease in overweight and obese adults and children. This article addresses the initial description of a physical activity intervention for children attending public elementary schools in Mexico. The objective was to develop a replicable model based on a strategic public, private, academic, and social partnership that would have a short-term impact on the metabolic health of children and be useful for building effective public policy. Forty-nine schools (20 000 students) participated, and 5 schools were selected for evaluation. The intervention included a 30-minute supervised middle-effort interchangeable routine, 5 days a week for a complete school year, adapted for different school conditions and students of different ages. Evaluation included anthropometric measurements and biochemical markers. Actual prevalence of combined overweight and obesity in these children was 31.9%. The intervention was successfully implemented in all schools. No change in body mass index, waist circumference, or other anthropometric indicators was found. However, changes in biochemical markers showed a significant decrease in blood glucose, total cholesterol, and cholesterol-low-density lipoproteins, reflecting a positive effect on cardiovascular health indicators. © The Author(s) 2016.

    In Mexico, the type of foods included in the lunchboxes of school children are unhealthy. The aim of this study was to evaluate the effects of an intervention program to improve the quality of the foods in the lunchboxes. Two schools were randomly selected as the intervention group (IG) and two more as the control group (CG). The evaluation was performed by comparing a food list from 3 days before and 6 months after the intervention. The components of the intervention included: exposure to posters inside and outside the classrooms and the distribution of pamphlets to parents, the pamphlets provided recipes and information about healthy foods. A lunchbox was considered adequate (AL) if it had less than 276 cal, fruits or vegetables, and an item prepared at home; a healthy lunchbox (HL) consisted of fruits or vegetables, water, and it did not have unhealthy foods. At the beginning of the study there were no significant differences in the compliance of AL and HL in both groups. By the end of the study, 19 % of the children in the IG and 10 % of the children in the CG met the criteria of a HL (p = 0.002). The results of this study demonstrate that a simple, 6 month intervention targeting parents improved the quality of the foods in the lunchboxes of second and sixth graders.

    School connectedness includes liking school and positive relations with teachers and peers. School connectedness is associated with a variety of positive health outcomes. The goal of this study was to identify characteristics of students, schools, and school neighborhoods that are related to school connectedness. In the Health Behavior in School-Aged Children (HBSC) Study, school connectedness was reported by 13,207 students (grades 6-10) in 340 schools. HBSC measured a variety of student characteristics. Characteristics of schools were culled from data maintained by Quality Education Data, and school neighborhood characteristics were derived from the 2000 decennial census. Associations between connectedness and student, school, and school neighborhood characteristics were estimated using hierarchical linear models. Characteristics of students, schools, and school neighborhoods were associated with school connectedness. Connectedness was greater among younger students, females, students with better academic performance and greater extracurricular involvement, students with greater self-rated physical attractiveness, students with more friends, students from 2-parent families, and students whose parents were more involved with school. Connectedness was greater in smaller schools, more racially homogeneous schools, and schools with more students from relatively wealthy households. School connectedness was higher in neighborhoods with a greater percentage of non-US citizens. As the percent of renters in the neighborhood increased beyond 20%, school connectedness tended to decrease. The findings point to possible strategies for fostering school connectedness.

    The low school attainment, early marriage, and low age at first birth of females are major policy concerns in less developed countries. This study jointly estimated the determinants of educational attainment, marriage age, and age at first birth among females aged 12-25 in Madagascar, explicitly accounting for the endogeneities that arose from modelling these related outcomes simultaneously. An additional year of schooling results in a delay to marriage of 1.5 years and marrying 1 year later delays age at first birth by 0.5 years. Parents' education and wealth also have important effects on schooling, marriage, and age at first birth, with a woman's first birth being delayed by 0.75 years if her mother had 4 additional years of schooling. Overall, our results provide rigorous evidence for the critical role of education-both individual women's own and that of their parents-in delaying the marriage and fertility of young women.

    Functional gastrointestinal disorders are among the most common chronic disorders in children worldwide. Studies in schoolchildren from various Latin American countries have shown a high prevalence of functional gastrointestinal disorders, but their prevalence in Mexican schoolchildren is unknown. Our aim was to assess the prevalence of functional gastrointestinal disorders in Mexican schoolchildren in accordance with the Rome III criteria. Children and adolescents from public and private schools in Monterrey and Cuernavaca privately completed the Spanish version of the Questionnaire on Pediatric Gastrointestinal Symptoms-Rome III Version (QPGS-III) in class, using the same methods and questionnaires of previous studies conducted by our group in other Latin American countries. A total of 362 schoolchildren (public school 82, private school 280), with a mean age of 11.6±2.1 years completed the QPGS-III. Ninety-nine schoolchildren (27.3%) met the criteria for a FGID, according to the Rome III criteria. Functional constipation was the most common FGID (12.6%). Irritable bowel syndrome (6.4%) was the most common FGID associated with abdominal pain. There was no significant difference in the prevalence of FGIDs between sexes (P=.8). We found a high prevalence of FGIDs in Mexican school-aged children and adolescents. Copyright © 2016 Asociación Mexicana de Gastroenterología. Publicado por Masson Doyma México S.A.

    This study had the following aims: to verify whether children living in different environmental areas present a different development degree of the functional prerequisites of psychomotricity; to test whether a targeted psychomotricity education program could favourably modify the potential differences which may be observed; to investigate the relationship, if any, between the anthropometric differences and the functional prerequisites of psychomotricity. One hundred and sixty-five Italian children, 83 males and 82 females, 6-7 years old were enrolled in this study. Based on the provenance area, the children were subdivided into two groups: the urban one (N=85) and the rural one (N=80). Both groups underwent an initial psychomotor assessment including standardised psychomotor tests aimed at evidencing the general dynamic coordination ability and the static and dynamic balance capacity of every child. The findings of this research point out that children living in an urban setting selectively showed a lower degree of balance development, if compared to children living in rural areas; a targeted psychomotor education program favourably modified the differences in the balance development between the two examined groups, up to their disappearance. In the urban group the body mass index had a trend towards a negative relationship with balance development. Children grown up in an urban environment showed a delay in balance development, if compared to children of the same age grown up in rural areas. This study also clearly proves that such a delay may be regained by means of a targeted psychomotor education program.

    Full Text Available Background. Although energy balance is the main factor that regulates body weight, recent studies suggest that calcium metabolism can modify the energy balance and help regulate body weight. Objective. To evaluate the association between the calcium intake in the diet and high body mass index in Mexican adults in the 20-59 age group. Material and methods. A cross-sectional secondary analytical study was conducted based on the 2006 Mexican National Health and Nutritional Survey (ENSANUT 2006. Food intake questionnaires applied to 16,494 adults were analyzed. After removing biologically implausible values or incomplete information, we arrived at a final sample of 15,662 adults grouped according to their body mass index. Linear regression was used to assess association between daily dietary calcium intake and body mass index. Results. There was an inverse association between dietary calcium consumption and a high body mass index. The mean calcium intake in subjects with normal body mass index was 903.9 mg/day versus 832.0 mg/day in obese subjects (p < 0.0001. Conclusion. The study corroborates existing evidence of an inverse association between the dietary calcium intake and a high body mass index.

    92.3% schoolchildren aged 6-13 years of a mexican rural village, suspected foci of Taenia solium cysticercosis were screened for intestinal parasites with the main purpose to know the infection rate by taeniasis. An stool sample was collected to schoolchildren of the village and 95.4% of a urban private school as comparative group. Laboratory examinations were performed with the most accurate technics, included microscopies with an ocular micrometer. The general parasitation rate was 4 times higher in the rural village, but the percentages of Taenia spp. infection were 0.6% both of them. Entamoeba histolytica was observed 1.8% and 7.2% in the city and rural village, respectively. All the cases with taeniasis passed T. saginata after treatment with niclosamide. Negative results were obtained with the same chemotherapy in a randomly selected group of 112 schoolchildren which previous stool examination was reported negative. Neither taeniasis were demonstrated in 94 adult persons. These data are suggestive of the great variability on the transmission rates of T. solium cysticercosis in endemic areas and illustrate the faced methodological problems to confirm the diagnosis of taeniasis. By other hand support the hypothesis that estimates of infection rates with E. histolytica have been overdiagnosed in the country.

    Identifying current major dietary sources of sodium can enhance strategies to reduce excess sodium intake, which occurs among 90% of US school-aged children. To describe major food sources, places obtained, and eating occasions contributing to sodium intake among US school-aged children. Cross-sectional analysis of data from the 2011-2012 National Health and Nutrition Examination Survey. A nationally representative sample of 2,142 US children aged 6 to 18 years who completed a 24-hour dietary recall. Population proportions of sodium intake from major food categories, places, and eating occasions. Statistical analyses accounted for the complex survey design and sampling. Wald F tests and t tests were used to examine differences between subgroups. Average daily sodium intake was highest among adolescents aged 14 to 18 years (3,565±120 mg), lowest among girls (2,919±74 mg). Little variation was seen in average intakes or the top five sodium contributors by sociodemographic characteristics or weight status. Ten food categories contributed to almost half (48%) of US school-aged children's sodium intake, and included pizza, Mexican-mixed dishes, sandwiches, breads, cold cuts, soups, savory snacks, cheese, plain milk, and poultry. More than 80 food categories contributed to the other half of children's sodium intake. Foods obtained from stores contributed 58% of sodium intake, fast-food/pizza restaurants contributed 16%, and school cafeterias contributed 10%. Thirty-nine percent of sodium intake was consumed at dinner, 31% at lunch, 16% from snacks, and 14% at breakfast. With the exception of plain milk, which naturally contains sodium, the top 10 food categories contributing to US schoolchildren's sodium intake during 2011-2012 comprised foods in which sodium is added during processing or preparation. Sodium is consumed throughout the day from multiple foods and locations, highlighting the importance of sodium reduction across the US food supply. Published by Elsevier

    Although the popular North American opinion of Mexico is one that paints a picture of a poor, disadvantaged country, South America sees Mexico has a richer more prosperous nation. It is observed that only in the Latin American countries of Venezuela, Suriname and Trinidad and Tobago do consumers have higher incomes than Mexican consumers. Moreover, while millions of Mexicans migrate to the United States to seek a better standard of living, several thousand Central American refugees illegally migrate to Mexico in search of a better life. This better life includes an increased age of lie expectancy from 51 years in the 1950s to 64 years in the late 1970s. There have also been improvements in health care and school enrollments and in the low cost availability of education. Tourism and the prospect of the manufacturing of energy are significant, positive factors working in favor of an improved Mexican economy and a higher overall quality of life. However, Mexico faces serious problems such as a mounting foreign debt. Also rising is Mexico's population which has doubled since 1964 and which continues to grow at a rate of 1.9%. Economic programs and reforms and family development planning have been instituted in response to the countries' current recession and population growth and have begun to show positive results.

    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.

    Food from lunch packs (LP) or food available inside and outside of school can play an important role in the development of obesity. The purpose of this study was to evaluate the LP of elementary school (ES) and preschool children (PS) in Tijuana, and the foods available to them inside and outside of school. Eight public schools participated in the study. A random sample of all the groups from a school district was conducted. A questionnaire was administered to children in first through sixth grade (ES) and to the parents of PS. LP and food available inside and outside of the school were classified as healthy, unhealthy, and adequate according to the guidelines set forth by the Secretariat of Health. A total of 2,716 questionnaires were administered and the content of 648 LP was assessed. It was observed that 99% of PS had LP prepared at home, a higher percentage than ES. None of the LP of the ES was classified as healthy, and 1% was classified as adequate. Among PS, 21% of the LP were classified as healthy and 6% as adequate. More than half of the children recognized the brand name of foods high in fat, salt, and added sugar available inside and outside of school grounds. Most of the LP of ES and PS and the foods available inside and outside of school were unhealthy and inadequate. A strategy to prevent the availability of unhealthy and inadequate food in LP and foods available inside and outside schools is recommended.

    Anemia affects approximately 25% of school-aged children (SAC-aged 5.00-14.99 years) globally. We determined in three countries the prevalence and determinants of anemia in SAC. Data on sociodemographics, inflammation and nutrition status were obtained from the 2006 Mexican National Nutrition Survey, the 2003-6 US National Health and Nutrition Examination Surveys, and the 2010 Encuesta Nacional de Nutrición Situación Colombia. In the US, vitamin A and iron deficiency (ID) were available only for girls aged 12.00-14.99 years to which our analysis was limited. Associations were evaluated by country using multivariable logistic regression adjusting for confounders and complex survey design. The prevalence of anemia and ID were: Mexico 12% (ID 18%), n = 3660; US 4% (ID 10%), n = 733; and Colombia 4% (ID 9%), n = 8573. The percentage of anemia associated with ID was 22.4% in Mexico, 38.9% in the US and 16.7% in Colombia. In Mexico, anemia was associated with ID (adjusted OR: 1.5, p = 0.02) and overweight (aOR 0.4, p = 0.007). In the US, anemia was associated with black race/ethnicity (aOR: 14.1, p Colombia, anemia was associated with black race/ethnicity (aOR: 1.6, p = 0.005), lowest socio-economic status quintile (aOR: 1.8, p = 0.0005), ID (aOR: 2.7, p < 0.0001), and being stunted (aOR: 1.6, p = 0.02). While anemia was uniformly associated with iron deficiency in Mexico, Columbia, and the United States, other measured factors showed inconsistent associations with anemia. Additional data on anemia determinants in SAC are needed to guide interventions.

    Study Goal was to determine dietary habits in school-aged children. Sampling of children was conducted in two stages. In the first stage, five schools in Nadzaladevi district of city Tbilisi were randomly selected. On the second stage the study groups from the appropriate school-aged students (10-14 years old children) were also randomly selected. All student participants filled out standardized and adopted questionnaires suggested by the American Academy of family physicians. Data were analyzed by using EpiInfo 7th version. Statistical analyses looked at correlations between criteria of unhealthy diet (such as morning without breakfast, frequent consumption of non-alcoholic beverages and fast food products) and overweight/obesity. A Body Mass Index (BMI) was calculated by using CDC tool. 175 children with ages of 10-14 years (47% boys) were included and interviewed. Half of the children noted that they love or like fast food products. 10% - visits fast food places 2-3 times a week together with a family. 11% - visits fast food places 5 times a week and even more. 34% - do not start morning with breakfast; 15% - eat only twice a day; 26% - add salt to their dishes; 58% - drink non-alcoholic beverages every day or many times during a week; 24% - are overweight; 29% suffer from obesity; 25% noted that fast food places are located near schools. Very weak correlation was found between unhealthy diet (morning without breakfast, frequent consumption of non-alcoholic beverages and fast food products) and overweight/obesity. According to study results, dietary habits of school-age children in Tbilisi is unhealthy; to improve nutritional habits is essential: (1) promote consumer (students, parents and teachers) awareness on a healthy diet, (2) educate children, adolescents and adults about nutrition and healthy dietary practices, (3) encourage to raise awareness about the salt consumption in recommended doses in children.

    Integrating U-Pb ages from zircons of syn- and postectonic intrusives emplaced in folded pre- and synorogenic marine sedimentary rocks, it is proposed that thin-skinned deformation in the Concepción del Oro salient of the Mexican Fold Thrust Belt in northern Zacatecas, Mexico, was active between 92 and 71.6 Ma. The intrusives Pico de Teyra and El Peñuelo (U-Pb zircon ages: 76.9 and 72.5 Ma) show internal tectonic foliations and horizontal shear zones that cut off aplitic veins, which apparently developed syntectonically to thin-skinned deformation. Other intrusives like Saltillito (71.6 Ma) and Concepción del Oro are clearly postectonic because they are undeformed internally, cut regional structures and are younger than syntectonic plutons. Biostratigraphic ages reported for synorogenic sediments (Concepción del Oro and Parras formations) indicate that regional thin-skinned deformation was active between Early Turonian and Late Campanian, which is in agreement with syn and postectonic intrusive emplacement ages in the area. Nevertheless, the thin-skinned structures are disrupted by a younger NNW-SSE high angle reverse and normal faults that uplifts the San Julián Block in the west and truncate the Concepción del Oro salient, suggesting a post-Paleocene thick-skinned stage of deformation. In this work, we propose that style and age of thin-skinned deformation is similar to the Sevier orogeny in the Rocky Mountains.

    The aim of this study was to analyze the relationship between creativity and physical fitness in elementary school children. Data were collected from 308 primary school students in southern Spain, ranging in age from 8 to 12 years (mean, 9.72 ± 1.25 years). They completed a fitness test battery, and the Prueba de Imaginación Creativa para Niños (PIC-N; Creative Imagination Test for Children) to analyze creativity. Significant differences were found between the sexes. Boys had better physical fitness but there were no sex differences in creativity. On clusters analysis, the highly creative groups had better physical fitness. Creativity was correlated with physical fitness. Aerobic capacity was a predictor of creativity. There is an association between creativity and physical fitness in primary school children that may have important implications for academic achievement. © 2017 Japan Pediatric Society.

    As the number of Mexican American school-aged children continues to increase, researchers, practitioners, and policymakers are in critical need of information to better understand and serve them. This study used structural equation modeling to examine the relationship among perceived parental educational involvement (PPEI), acculturation, gender, and self-esteem on the academic achievement and aspirations of Mexican American high school students (N = 298). Results revealed direct effects of perceived parental educational involvement, students' level of acculturation, and students' self-esteem on students' achievement and aspirations. Acculturation and self-esteem also revealed indirect effects on aspirations and achievement through parental educational expectations. Implications of these findings are discussed.

    The most common cause of anemia is a deficiency of iron; but it may also be caused by deficiencies of folates, vitamin B12 and protein. Some anemias are not caused by nutritional factors, but by congenital factors and parasitic diseases such as malaria. This study attempted to estimate the prevalence of anemia among pre-school and school- aged children in two rural areas of Odogbolu Local government area, and to determine whether its cause was nutritional or could be attributed to malaria. A total of 177 children between the ages of 2 and 11 years were included in the study. Children were examined for malaria parasites by microscopy. The World Health Organization (WHO) age-adjusted cut-off for hemoglobin and hematocrit were used to classify anemia. An enzyme linked immunosorbent assay for serum ferritin was compared with standard methods of determining iron deficiency. Under-nutrition (stunting, wasting and underweight) was classified according to the National Centre for Health Statistics standards. Values below-2SD were defined as mild-moderate under-nutrition, and those below-3SD as severe malnutrition. Most of the children were anemic, 87.1%, having PCV values below the 32% cut-off and 95% with hemoglobin levels lower than the 11 g/dl, although parasite prevalence and density were low. Malnutrition was patent; 36% of the children were stunted, 18.3% wasted and 44.2% underweight. Serum ferritin was more sensitive than PCV in detecting anemic children. Although anemia was higher in boys and preschoolers compared to girls and school aged children, the difference was significant only in preschoolers (P? = ?.004). Anaemia was also significantly higher in Irawo village school than in Iloti (P? = ?.0001) The anemia detected in this population may be due more to under-nutrition than to malaria.

    Associate learning is fundamental to the acquisition of knowledge and plays a critical role in the everyday functioning of the developing child, though the developmental course is still unclear. This study investigated the development of visual associate learning in 125 school age children using the Continuous Paired Associate Learning task. As hypothesized, younger children made more errors than older children across all memory loads and evidenced decreased learning efficiency as memory load increased. Results suggest that age-related differences in performance largely reflect continued development of executive function in the context of relatively developed memory processes.

    The main purpose of the study was to explore the child sexual behaviors that Italian teachers have observed in the school context. A representative sample of 227 children, from 5 to 10 years old, was rated by their teachers through the Child Sexual Behavior Inventory. Frequencies of sexual behaviors among children aged 5 to 6, 7 to 8, and 9 to 10 are presented. Younger children showed a broader range of sexual behaviors that decrease with the growing age, such as males in comparison to females. Moreover, findings showed that child sexual behavior is not only related to age and gender but also to family characteristics. These results suggested that child sexual behaviors reported by teachers through the Child Sexual Behavior Inventory may provide useful information about the development of children's sexuality. The knowledge of age appropriate sexual behaviors can help teachers discern normal sexual behaviors from problematic sexual behaviors.

    Full Text Available Purpose: The purpose of the study was to define the epidemiology of dyspraxia among children from 6 to10 years’ age, attending grades I-III of primary schools in Wrocław, Poland. Material: the study was conducted among pupils of primary schools in Wrocław, Poland. The studied groups included 48 girls and 52 boys. The study employed Polish version of Questionnaire for the screening assessment of dyspraxia’s occurrence among children from 5 to 15 years’ age (DCDQ-PL, as well as the Coordination Test for Children (KTK. Results. After assessing the occurrence of dyspraxia among studied children, it was found out that this disorder is present in the studied group. The prevalence of dyspraxia depends on studied children’s gender; however, it is not related to their age. The results of tests, conducted with the DCDQ-PL and the KTK are consistent and confirm the observed inter-dependencies. Conclusions. Dyspraxia is a widespread psychomotor disorder, which can be diagnosed among children in the early school years. A diagnosis of a child’s development with respect to this disorder should constitute a constant element of work for teachers and educationists dealing with children at this stage of education.

  16. Age Trajectories of Poverty During Childhood and High School Graduation

    Full Text Available This article examines distinct trajectories of childhood exposure to poverty and provides estimates of their effect on high school graduation. The analysis incorporates three key insights from the life course and human capital formation literatures: (1 the temporal dimensions of exposure to poverty, that is, timing, duration, stability, and sequencing, are confounded with one another; (2 age-varying exposure to poverty not only affects, but also is affected by, other factors that vary with age; and (3 the effect of poverty trajectories is heterogeneous across racial and ethnic groups. Results from the Children of the National Longitudinal Survey of Youth show that any extended exposures to poverty substantially lower children’s odds of graduating from high school. Persistent, early, and middle-to-late childhood exposures to poverty reduce the odds of high school graduation by 77 percent, 55 percent, and 58 percent, respectively, compared to no childhood exposure to poverty. The findings thus suggest that the impact of poverty trajectories is insensitive to observed age-varying confounders. These impacts are more pronounced for white children than for black and Hispanic children.

    Behavioral problems are often associated with poor sleep habits in children. We investigated whether undesirable toddler-age sleep schedules may be related to school-age behavioral problems. We analyzed the data of a nationwide longitudinal survey with available results from 2001 to 2011. The participants were 41,890 children. The predictors were waking time and bedtime at 2years of age, and the outcomes were assessed by determining the presence or absence of three attention problems and four aggressiveness problems at 8years of age. In logistic regression models with adjustments for confounding factors, we estimated odds ratios (ORs) and confidence intervals (CIs) for the association between toddler sleep schedules and behavior during primary-school age years. The outcomes of attention problems and aggressiveness problems were observed in 1.7% and 1.2% of children, respectively, at 8years of age. The OR of an irregular or late morning waking time at 2years of age with the outcome of aggressiveness problems was 1.52 (95% CI, 1.04-2.22) in comparison to an early waking time. The OR of an irregular or late bedtime with attention problems was 1.62 (95% CI, 1.12-2.36), and the OR of an irregular or late bedtime with aggressiveness problems was 1.81 (95% CI, 1.19-2.77) in comparison to an early bedtime. Poor toddler-age sleep schedules were found to predict behavioral problems during primary-school age years. Thus, good and regular sleep habits appear to be important for young children's healthy development. Copyright © 2014 The Japanese Society of Child Neurology. Published by Elsevier B.V.

    Full Text Available Childhood arterial hypertension (AH has become a global problem not only for pediatrics, but also for public health in general. Objective. The aim of this study was to determine the prevalence of arterial hypertension among school-age children and diagnostic value of pulse pressure. Materials and Methods. In total 848 children in 10–17 years of age (mean age – 13.9 ± 0.06 years, 45.4 % boys and 54.6 % girls from urban and rural areas of Chernivtsi region were examined in schools during screening for elevated blood pressure (BP. School-based ambulatory seated BP was measured by oscillometric automated recording devices with the age selection of cuffs. Elevated systolic (SAP or diastolic (DAP pressure was diagnosed in those children with indicators above the 95th percentile of age norms in accordance with the national normative values. In cases of elevated BP the measurements were verificated by aneroid device. Results. It has been established that the frequency of high blood pressure in the examined school students was 25.2 %, including 17.7 % of arterial hypertension (BP above 95 percentile and 7.5 % – pre-hypertension (90–95 percentile. The prevalence of hypertension varied with age subgroups and the highest level was in 16 years of age – 29.9 % with high blood pressure (21.9 % above 95 percentile and 8.0 % between the 90th and 95th percentiles. Increased SAP was combined with an increased DAP in 47.3 % of cases and in the study had a positive correlation with overweight (r = 0.27, p < 0.05 and negative with physical performance (r = -0.21, p < 0.05. The pulse pressure had significant correlations with SAP, AH and overweight and it could be used as additional diagnostic index of AH. Conclusions. The prevalence of elevated BP in our study is higher than in European countries and exceeds 20 % of the child population. The elevated BP in our children has positive correlation with overweight and the negative with physical performance. The

    We aimed to examine if sleep architecture was altered in school-aged children with primary snoring (PS). Children ages 6 to 13 years from 13 primary schools were randomly recruited. A validated obstructive sleep apnea (OSA) screening questionnaire was completed by their parents. Children at high risk for OSA and a randomly chosen low-risk group were invited to undergo overnight polysomnography (PSG) and clinical examination. Participants were classified into healthy controls, PS, mild OSA, and moderate to severe OSA (MS OSA) groups for comparison. A total of 619 participants underwent PSG (mean age, 10.0 ± 1.8 years; 396 (64.0%) boys; 524 (84.7%) prepubertal). For the cohort as a whole, there were no significant differences in measures of sleep architecture between PS and nonsnoring healthy controls. In the multiple regression model, percentage of nonrapid eye movement (NREM) stage 1 (N1) sleep had a significantly positive association, whereas percentage of slow-wave sleep (SWS) had a significantly negative association with sleep-disordered breathing (SDB) severity after controlling for age, gender, body mass index (BMI) z score, and pubertal status. In prepubertal children with PS, no significant disruption of sleep architecture was found. However, pubertal adolescent PS participants had significantly higher adjusted percentage of N1 sleep and wake after sleep onset (WASO) compared to healthy controls. PS did not exert significant adverse influences on normal sleep architecture in prepubertal school-aged children. Nevertheless, pubertal adolescents with PS had increased N1 sleep and WASO.

    Suicide in elementary school-aged children is not well studied, despite a recent increase in the suicide rate among US black children. The objectives of this study were to describe characteristics and precipitating circumstances of suicide in elementary school-aged children relative to early adolescent decedents and identify potential within-group racial differences. We analyzed National Violent Death Reporting System (NVDRS) surveillance data capturing suicide deaths from 2003 to 2012 for 17 US states. Participants included all suicide decedents aged 5 to 14 years (N = 693). Age group comparisons (5-11 years and 12-14 years) were conducted by using the χ 2 test or Fisher's exact test, as appropriate. Compared with early adolescents who died by suicide, children who died by suicide were more commonly male, black, died by hanging/strangulation/suffocation, and died at home. Children who died by suicide more often experienced relationship problems with family members/friends (60.3% vs 46.0%; P = .02) and less often experienced boyfriend/girlfriend problems (0% vs 16.0%; P suicide note (7.7% vs 30.2%; P suicide decedents with known mental health problems (n = 210), childhood decedents more often experienced attention-deficit disorder with or without hyperactivity (59.3% vs 29.0%; P = .002) and less often experienced depression/dysthymia (33.3% vs 65.6%; P = .001) compared with early adolescent decedents. These findings raise questions about impulsive responding to psychosocial adversity in younger suicide decedents, and they suggest a need for both common and developmentally-specific suicide prevention strategies during the elementary school-aged and early adolescent years. Further research should investigate factors associated with the recent increase in suicide rates among black children. Copyright © 2016 by the American Academy of Pediatrics.

    The Gente Joven project of the Mexican Foundation for Family Planning (MEXFAM) trains young volunteers in 19 cities to spread messages about sexually transmitted diseases and population growth to their peers. They also distribute condoms and spermicides. It also uses films and materials to spread its messages. The project would like to influence young men's behavior, but the Latin image of machismo poses a big challenge. It would like to become more responsible toward pregnancy prevention. About 50% of adolescents have sexual intercourse, but few use contraceptives resulting in a high adolescent pregnancy rate. Many of these pregnant teenagers choose not to marry. Adolescent pregnancy leads to girls leaving school, few marketable skills, and rearing children alone. Besides women who began childbearing as a teenager have 1.5 times more children than other women. Male involvement in pregnancy prevention should improve these statistics. As late as 1973, the Health Code banned promotion and sales of contraceptives, but by 1992 about 50% of women of reproductive age use contraceptives. The Center for the Orientation of Adolescents has organized 8 Young Men's Clubs in Mexico City to involve male teenagers more in family planning and to develop self-confidence. It uses a holistic approach to their development through discussions with their peers. A MEXFAM study shows that young men are not close with their fathers who tend to exude a machismo attitude, thus the young men do not have a role model for responsible sexual behavior. MEXFAM's work is cut out for them, however, since the same study indicates that 50% of the young men believe it is fine to have 1 girlfriend and 33% think women should earn more than men. A teenager volunteer reports, however, that more boys have been coming to him for contraception and information than girls in 1992 while in other years girls outnumbered the boys.

    2015-05-01

    School bullying continues to be a serious problem around the world. Thus, it seems crucial to clearly identify the risk factors associated with being a victim or a bully. The current study focused in particular on the role that age and socio-economic differences between classmates could play on bullying. Logistic and multilevel analyses were conducted using data from 53,316 5th and 9th grade students from a representative sample of public and private Colombian schools. Higher age and better family socio-economic conditions than classmates were risk factors associated with being a bully, while younger age and poorer socio-economic conditions than classmates were associated with being a victim of bullying. Coming from authoritarian families or violent neighborhoods, and supporting beliefs legitimizing aggression, were also associated with bullying and victimization. Empathy was negatively associated with being a bully, and in some cases positively associated with being a victim. The results highlight the need to take into account possible sources of power imbalances, such as age and socio-economic differences among classmates, when seeking to prevent bullying. In particular, interventions focused on peer group dynamics might contribute to avoid power imbalances or to prevent power imbalances from becoming power abuse. Aggr.

    2014-08-01

    To investigate endorsement patterns among the 18 DSM-IV symptoms of ADHD in a longitudinal sample of children with and without ADHD (n = 144), as assessed at ages 4-5, 5-6, and 6-7 years. Symptom endorsements and diagnoses were determined at all time-points via K-SADS-PL interview administered to parents and supplemented by teacher questionnaires and clinician observations. Changes in endorsement patterns over time for each of the 18 DSM-IV symptoms were ascertained. Several symptoms, particularly those of inattention, were infrequently endorsed and of apparently limited diagnostic utility at ages 4-5; hyperactive/impulsive symptoms were more frequently endorsed among young children with ADHD than were inattentive symptoms. However, by ages 6-7, inattention items were somewhat superior at discriminating ADHD from Non-ADHD children. Several DSM-IV and now DSM-V symptoms provide limited diagnostic differentiation prior to school-age, particularly those most commonly observed in the context of formal schooling. Consideration should be made in future iterations of the DSM that account for such developmental and contextual differences.

    Accurate age estimation has always been a problem for forensic scientists, and apposition of secondary dentine is often used as an indicator of age. Cameriere et al. studied the pulp/tooth area ratio by peri-apical X-ray images of the canines, to observe the apposition of secondary dentine. The present study examines the application of this technique in a Mexican identified sample coming from the Department of Physical Anthropology of the INAH, at Mexico City. The main aim of this work is to test the reliability of this method in a skeletal sample of a specific population, different from the samples used for its development. The obtained regression model explained 96.2% of total variance (R(2) = 0.962) with a standard error of estimate of 1.909 and a standard deviation of 1.947. These results demonstrate great reliability and that the age/secondary dentine relationship is not variable in this specific population. © 2011 American Academy of Forensic Sciences.

  12. The role of play in pre-school and younger school age children

    Directory of Open Access Journals (Sweden)

    Kopas-Vukašinović Emina

    2006-01-01

    Full Text Available The paper deals with the importance of play for children’s development and learning in institutionalized preschool education, as well as the opportunities it provides concerning the organization of teaching activities with younger school age children. The paper is based on the theoretical framework emphasizing educational character of children’s play, as a specific form of learning. Notwithstanding occasional attempts within pedagogic theory to deny educational values of children’s play and to emphasize instruction as the only form of systematic learning, contemporary pedagogic views consider play an important part of school education. Learning through play at younger school age helps overcome the discontinuity between preschool and school education. Curriculum subject matter can be covered through carefully selected and prepared play activities within the existing system, providing the support, encouragement and guidance by the adults involved, including their proper knowledge of children’ age-related and psycho-physical characteristics. Play facilitates gradual change over from preschool to school developmental stage, free, spontaneous and creative expression and the development of children’s potential.

    2012-01-01

    School-age children report much stress in their daily lives, which may lead to psychological and physical problems. Mindfulness-based Stress Reduction is a program of awareness-based practices effective with adults. The purpose of this study was to investigate the efficacy of mindfulness training through yoga with school-age girls to reduce perceived stress, enhance coping abilities, self-esteem, and self-regulation, and explore the relationship between the dose of the intervention and outcomes. Fourth- and fifth-grade girls were recruited from two public schools and randomly assigned to intervention and wait-list control groups. The intervention group met 1 hour a week for 8 weeks and completed 10 minutes of daily homework. Self-esteem and self-regulation increased in both groups. The intervention group was more likely to report greater appraisal of stress (p stress. Consistent with reports of mindfulness training, greater awareness of the feelings associated with stress may enhance coping abilities. However, it is possible that the increasing awareness of stressors in itself increased stress, possibly as part of the process of developing mindfulness or related to cognitive, emotional, or social development. Mindfulness in children may differ from mindfulness in adults and warrants further investigation. Copyright © 2012 National Association of Pediatric Nurse Practitioners. Published by Mosby, Inc.

    The purpose of this study was to (i) investigate attitude and menstruation-related practices in Jordanian school-aged girls; (ii) identify the influence of premenstrual preparation on girls' attitude and menstruation-related practices. A descriptive cross-sectional design was used. Data was collected from a convenience sample of 490 school-age girls (12-18 years) from different districts in Jordan. Self-report instruments [Menstrual Attitude Questionnaire (MAQ), and Menstrual Practices Questionnaires (MPQ)] were used to assess the study variables. Descriptive statistics, correlation and chi-square tests were used to analyze the data. It was found that menstrual attitude and practices were positively correlated. Poor attitude toward menstruation and low menstrual practices were significantly associated with inadequate premenstrual preparation. There is a need to prepare girls for menstruation before menarche. The role of the schools and teachers should be reinforced through formal and well planned reproductive health educators for girls and their mothers. © 2012 Blackwell Publishing Asia Pty Ltd.

    To provide head circumference references for school-aged children in western Romania, and compare them with references from other European countries. A total of 2742 children, aged 6-19 years, from Timis county, were examined by medical students, between February 2010-June 2011. Head circumference references were constructed by Cole's LMS method with LMSChartMaker software. The Romanian 3rd, 50th and 97th percentiles for head circumference were compared with recent references from Belgium and Germany. Generally, boys show significantly larger head circumference compared to girls at any age. The head circumference increments between 6 and 19 years are Romania to those from Germany and Belgium, we found lower median head circumference in Romanian boys and girls, that could be explained by a taller stature of boys and girls in Germany and Belgium compared to Romania.

The present series of studies aimed to shed light on sleep patterns, on the longitudinal association of sleep with school performance, and on practical intervention strategy for Chinese school-aged children. METHODS AND FINDINGS: A serial sleep researches, including a national cross-sectional survey, a prospective cohort study, and a school-based sleep intervention, were conducted in China from November 2005 through December 2009. The national cross-sectional survey was conducted in 8 cities and a random sample of 20,778 children aged 9.0±1.61 years participated in the survey. The five-year prospective cohort study included 612 children aged 6.8±0.31 years. The comparative cross-sectional study (baseline: n = 525, aged 10.80±0.41; post-intervention follow-up: n = 553, aged 10.81±0.33 was undertaken in 6 primary schools in Shanghai. A battery of parent and teacher reported questionnaires were used to collect information on children's sleep behaviors, school performance, and sociodemographic characteristics. The mean sleep duration was 9.35±0.77 hours. The prevalence of daytime sleepiness was 64.4% (sometimes: 37.50%; frequently: 26.94%. Daytime sleepiness was significantly associated with impaired attention, learning motivation, and particularly, academic achievement. By contrast, short sleep duration only related to impaired academic achievement.

    2017-06-01

    Full Text Available Background: Children between the ages of 5 and 14 appear to have a lower risk of dying than both younger and older individuals. Objective: We looked for possible factors influencing the mortality rates of school-age children in Norway during the German occupation from 1940 to 1945, i.e., at a time of poverty and moderate food shortage - and before the general use of vaccines. Methods: We used Norwegian mortality data by age and sex, during the period of 1930-1954, from the Human Mortality Database and obtained the main causes of death, as well as age-specific data from different regions of Norway, from Statistics Norway. Results: Boys and girls aged 5-14 years had lower mortality rates than any other age group below 40, even during the German occupation. However, 5-14-year-old boys as well as 5-9-year-old girls had significantly increased mortality during 1941-1945 as compared to the previous decade. Mortality as a result of diphtheria, pertussis, scarlet fever, and measles increased more than five-fold, surpassing mortality as a result of accidents, whereas mortality from these infections only doubled in adults up to 39 years. During that same period, the body weight of schoolchildren aged 8-13 years dropped slightly. Conclusions: Proper nourishment, being of the utmost importance for a functioning immune system, is key to understanding the potential vulnerability of children at any age. Our study shows how vulnerable even the most resistant children can be. Contribution: The vulnerability of children 5-14 years old may not have been properly taken into account, as was also shown in the recent upward UN revision of 5-14 age mortality in low- and middle-income countries.

The sample consists of 90 typical developed children, aged between 6 and 9. The sample includes 47 (52.2% girls and 43 (47.8% boys from preschool institutions and elementary schools in Pirot and Belgrade. Action representation in dynamic drawings was evaluated using three types of drawings: a man who runs, a man shooting a ball and a man lifting a ball from the floor. We determined that a very small number of the respondents reaches the highest level of graphical representation of figures in motion, and that girl’s achievements are better than boy’s achievements. However, this result is on the border of statistical significance (p=0.052. Also, there is a statistically significant trend of progress to higher levels of action representation (p=0.000 with the increase in chronological age of the respondents.

    Converging data suggest recovery from injury in the preterm brain. We used functional magnetic resonance imaging (fMRI) to test the hypothesis that cerebral connectivity involving Wernicke's area and other important cortical language regions would differ between preterm (PT) and term (T) control school age children during performance of an auditory language task. Fifty-four PT children (600-1250 g birth weight) and 24 T controls were evaluated using an fMRI passive language task and neurodevelopmental assessments including: the Wechsler Intelligence Scale for Children - III (WISC-III), the Peabody Individual Achievement Test - Revised (PIAT-R) and the Peabody Picture Vocabulary Test - Revised (PPVT-R) at 8 years of age. Neural activity was assessed for language processing and the data were evaluated for connectivity and correlations to cognitive outcomes. We found that PT subjects scored significantly lower on all components of the WISC-III (planguage function at school age differently than T controls; these alterations may represent a delay in maturation of neural networks or the engagement of alternate circuits for language processing.

    Exposure to traumatic events during childhood is often associated with the development of psychiatric disorders, cognitive impairment, and poor functioning in adulthood. However, few studies have examined cognitive function, including executive function, memory, and attention, in school-aged children with early trauma compared with age- and sex-matched controls. We recruited 30 medication-naive children between 5 and 12 years of age with a history of early severe trauma from a foster care home, along with 30 age- and sex-matched controls. Psychiatric diagnoses were based on Kiddie Schedule for Affective Disorders and Schizophrenia Epidemiologic Version (K-SADS-E) for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria and were confirmed with a clinical interview. The neuropsychologic battery was tailored to assess broad cognitive domains such as learning/working memory, executive function, attention, verbal/premorbid intellectual functioning, and impulsivity. There was a higher prevalence of subsyndromal symptoms in children with a history of childhood trauma, although they rarely met all of the diagnostic criteria for a disorder. Moreover, lower estimated intellectual functioning scores were associated with subsyndromal symptoms in children with a history of trauma, and they performed more poorly on the Digits Span Test of the Wechsler Intelligence Scale for Children-III Edition, suggesting attention impairment. There is a high prevalence of subsyndromal symptoms in school-aged children with trauma and an attention impairment, which may contribute to a cumulative deficit early in cognitive development. These findings further support the need for early interventions that can prevent cognitive impairment when childhood trauma occurs. Copyright © 2012 Elsevier Inc. All rights reserved.

    Research regarding executive functioning (EF) in children rarely focuses on populations in African or Middle-Eastern Arabic-speaking countries. The current study used a cross-sectional design to examine the developmental trajectories of school-age Tunisian children in three domains of executive control (inhibition of prepotent responses, cognitive flexibility, and working memory) as well as their mutual interactions and the effects of gender and parents' education level. Inhibitory processes, cognitive flexibility, and working memory were assessed using the Stroop test, a version of the Hayling test adapted for children, simple and alternating tasks of verbal fluency, and verbal and visuospatial span tasks (forward and backward spans). The study population included 120 7- to 12-year-old Tunisian children (60 girls, 60 boys) who were grouped and matched for age, gender, and parents' education level. The results revealed an overall effect of age on executive performance, whereas gender and parents' education level showed non-significant effects. In addition, executive indices were significantly associated with fluid intelligence level. Partial correlation analyses (controlled for age) found significant links between indices that assessed the same executive process, except for inhibitory processes; the temporal indices for inhibitory processes showed relative independence. The correlations between indices that assessed distinct executive processes were weaker (but significant). Overall, the results suggest that executive components in school-age Tunisian children operate according to relatively homogeneous developmental trajectories, marked by peaks of maturity that differ according to the assessed index. A transcultural approach to EF is discussed in terms of the unity and diversity of its components.

    Purpose To investigate the association of age-related macular degeneration (AMD)–high risk alleles of the complement factor H (CFH), complement factor B (CFB), complement component 2 (C2), complement component 3 (C3), and age-related maculopathy susceptibility 2 (ARMS2) genes in a Mexican population for the first time. Methods Genotyping was performed for the Y402H variant of CFH, for the L9H, R32Q, and K565E variants of CFB, the E318D variant of C2, the A69S variant of ARMS2, and the R102G variant of C3 in 159 Mexican mestizo patients at advanced stages of AMD, i.e., CARMS (Clinical Age-Related Maculopathy Staging System) grade 4 or 5. The frequency of these variants was also investigated in a group of 152 control subjects without AMD. Genomic DNA was extracted from blood leukocytes, and genotyping was performed using PCR followed by direct sequencing. Allele-specific restriction enzyme digestion was used to detect the R102G polymorphism in C3. Results There were significant differences in the allelic distribution between the two groups for CFH Y402H (p=1×10−5), ARMS A69S (p=4×10−7), and CFB R32Q (p=0.01). The odds ratios (95% confidence interval) obtained for the risk alleles of these three variants were 3.8 (2.4–5.9), 3.04 (2.2–4.3), and 2.5 (1.1–5.7), respectively. Haplotype analysis including the two most significantly associated alleles (CFH Y402H and ARMS A69S) indicated that the C-T combination conferred an odds ratio (95% confidence interval) of 6.9 (3.2–14.8). The exposed attributable risk for this particular haplotype was 85.5%. Conclusions This is the first case-control investigation of AMD–high risk alleles in a Latino population. Our results support that CFH, ARMS2, and CFB AMD-risk alleles are consistently associated with the disease, even in ethnic groups with a complex admixture of ancestral populations such as Mexican mestizos.

    2012-01-01

    This project examined the unique predictive validity of parent ratings of toddler-age aggression, oppositionality, inattention, and hyperactivity-impulsivity to academic achievement at school-age in a sample of 566 high-risk children and families. The study also investigated potential indirect effects of the Family Check-Up on school-age academic achievement through changes in child behavior problems. The results demonstrated that toddler-age aggression was most consistently associated with school-age academic achievement, albeit modestly. Moreover, findings showed that the intervention predicted greater decreases in aggression from ages 2-3 to 4-5 compared to controls. The results suggest that in high-risk toddler-aged children, aggression may be a more consistent predictor of school-age academic achievement than other externalizing dimensions, which has implications for early identification and efforts to promote children's adaptation.

    Rural women have limited access to breast cancer education, which partially contributes to late diagnosis and treatment. In this pilot study, we tested the feasibility of implementing a school-based breast cancer educational program for adolescents in a rural Mexican community. We hypothesized that the adolescents' knowledge on breast cancer would increase as a result of the program, and that there would be intergenerational transmission of that knowledge to their older female relatives. Female adolescents from a rural middle school received the educational program. The program would be considered feasible and acceptable if more than 75% reported being satisfied with its contents. Changes in knowledge in the students and their relatives were evaluated using baseline and 4 months follow-up questionnaires. One hundred twenty-six students were enrolled. The program was considered acceptable by 96% of the participants. The students' knowledge regarding breast cancer increased significantly from baseline to 4 months follow-up (63% to 82%). One hundred ninety-four female relatives completed the initial knowledge questionnaires. The relatives' knowledge regarding breast cancer showed a significant increase from baseline to 4 months follow-up (55% to 61%). Implementing breast cancer educational programs for adolescents in rural communities is feasible and acceptable. The program increased the adolescents' knowledge on breast cancer, and promoted the intergenerational transmission of that knowledge to their female relatives. Intergenerational transmission of knowledge represents a potential method for providing population-based health awareness education globally. In limited-resource settings, education is a valuable tool for achieving early detection and downstaging of breast cancer. Unfortunately, rural women lack access to educational opportunities and information about breast cancer, which is a factor contributing to late diagnosis and treatment. In this study, we

    The objective of this study was to develop and evaluate the effectiveness of a school-based sleep education program aimed at improving the sleep and academic performance of school-age children. Using a community-based participatory research approach, we created a school-based sleep education program, "Sleep for Success"™ (SFS), composed of four distinct modules that addressed the children, their family and community, the school staff, and decision makers within the school setting. Implementation was carried out in three elementary schools. Seventy-one students participated in the evaluation of the program. The effectiveness of the SFS program was evaluated using non-randomized controlled before-and-after study groups (intervention and control) assessed over two time points (pre- and post-program implementation). Before (baseline) and after implementation, sleep and academic performance were measured using actigraphy and report card marks, respectively. In the intervention group, true sleep was extended by 18.2 min per night, sleep efficiency improved by 2.3%, and sleep latency was shortened by 2.3 min, and report card grades in mathematics and English improved significantly. No changes were noted in the control group. Participation in the sleep education program was associated with significant improvements in children's sleep and academic performance.

    This study explored the ability of elementary school age children to comprehend six idiomatic expressions. Eighty linguistically normal children, 20 from each of four different grade levels (kindergarten, second grade, fourth grade, and sixth grade) participated as subjects. All of the children completed a task designed to probe comprehension of specific idioms. A short story was presented, after which the subjects were required to identify events in the story, which were described using idiomatic phrases. When examined as a group, comprehension of the idioms studied improved with increasing age. However, when examined individually, performance was found to be highly variable from idiom to idiom. These results are discussed with regard to clinical implications in the assessment and management of language-disordered children.

    Objective: The study examined executive function deficits (EFD) in school-age children (7 to 14 years) with ADHD. Method: A clinical sample of children diagnosed with ADHD (n = 49) was compared to a population sample (n = 196) on eight executive function (EF) measures. Then, the prevalence of EFD...... in clinical and non-clinical children was examined at the individual level according to three methods previously applied to define EFD, and a fourth method was included to control for the effect of age on performance. Results: Children with ADHD were significantly more impaired on measures of EF than children...... without ADHD at the group level. However, only about 50% of children with ADHD were found to have EFD at the individual level, and results appeared relatively robust across methods applied to define EFD. Conclusion: As a group, children with ADHD displayed more problems on neuropsychological measures...

    The objective of this study, focused on parents and children to reduce sedentary behavior, consumption of soft drinks and high-fat and salt containing snacks, and increase the consumption of fruits and vegetables, was to assess the effect of a six month intervention and an 18 month follow-up intervention on the body mass index, food consumption and physical activity of 2nd and 3rd grade elementary school children. This was a randomized cluster controlled trial. School children were selected from 2nd and 3rd (n = 532) grade. BMI z-score for age and sex was calculated and classified according to the WHO (2006). Abdominal obesity was defined as WC > 90th of NHANES III. At six months of the study differences were observed in BMI, -0.82 (p = 0.0001). At 24 months, results such as an increase of z-score BMI and waist circumference, a decrease in abdominal obesity, eighth per cent remission and an incidence of 18% of overweight and obesity were observed. Additionally, an increase (p = 0.007) in vegetable intake and physical activity (p = 0.0001) was also reported, along with a decrease in sedentary activities and the consumption of snacks high in fat and salt. The results of this study indicate that with a comprehensive intervention there is a positive response to lifestyle changes and a reduction of abdominal obesity.

    Mexican-origin parents’ work experiences are a distal extra-familial context for adolescents’ adjustment. This two-wave multi-informant study examined the prospective mechanisms linking parents’ work conditions (i.e., self-direction, work pressure, workplace discrimination) to adolescents’ adjustment (i.e., educational expectations, depressive symptoms, risky behavior) across the transition to high school drawing on work socialization and spillover models. We examined the indirect effects of parental work conditions on adolescent adjustment through parents’ psychological functioning (i.e., depressive symptoms, role overload) and aspects of the parent-adolescent relationship (i.e., parental solicitation, parent-adolescent conflict), as well as moderation by adolescent gender. Participants were 246 predominantly immigrant, Mexican-origin, two-parent families who participated in home interviews when adolescents were approximately 13 and 15 years of age. Results supported the positive impact of fathers’ occupational self-direction on all three aspects of adolescents’ adjustment through decreased father-adolescent conflict, after controlling for family socioeconomic status and earner status, and underemployment. Parental work pressure and discrimination were indirectly linked to adolescents’ adjustment, with different mechanisms emerging for mothers and fathers. Adolescents’ gender moderated the associations between fathers’ self-direction and girls’ depressive symptoms, and fathers’ experiences of discrimination and boys’ risk behavior. Results suggest that Mexican-origin mothers’ and fathers’ perceptions of work conditions have important implications for multiple domains of adolescents’ adjustment across the transition to high school.

    Chronic school absenteeism and frequent school changes, particularly among younger children, may be antecedents for the high rates of school failure and subsequent dropout among youth in foster care. However, the relationship of foster care experience to absenteeism and school change has not been well studied. This study examined the association of placement experience with absenteeism and changing schools among 209 urban children in foster care enrolled in public elementary schools. A cohort of children aged 5 to 8 years who entered non-relative or kinship foster care from 2006-2008 were followed longitudinally for 2 years from entry into foster care. Children residing in foster care were categorized at the end of the study as early stable, late stable, or unstable, if they achieved a permanent placement prior to 45 days, between 45 days and 9 months, or failed to do so within 9 months, respectively. Children who reunified home were classified as a fourth category. Poisson regression, controlling for baseline factors, was used to compare days absent and number of schools attended across categories of placement experience. Among the 209 children, 51% were male, 79% were African American, and 55% were initially placed with kin. One third of children reunified home; among children who did not reunify, one half was early stable, and a third was unstable. Adjusted rates of school absenteeism increased in stepwise fashion as children's placements became more unstable; children with unstable placements were 37% more likely to be absent than those with early placement stability (p=0.029). Children who reunified during the study demonstrated the highest rates of absenteeism; however, there was no significant difference in absenteeism before or after reunification. Number of schools attended increased as stability worsened, with the standardized rate of schools attended reaching 3.6 schools (95% CI 3.1-4.1) over a two year period among children in unstable placements.

    In this study, curvilinear regression was applied to the relationship between BMI and body fat percentage, and an analysis was done to see whether there are characteristic changes in that curvilinear regression from elementary to middle school. Then, by simultaneously investigating the changes with age in BMI and body fat percentage, the essential differences in BMI and body fat percentage were demonstrated. The subjects were 789 boys and girls (469 boys, 320 girls) aged 7.5 to 14.5 years from all parts of Japan who participated in regular sports activities. Body weight, total body water (TBW), soft lean mass (SLM), body fat percentage, and fat mass were measured with a body composition analyzer (Tanita BC-521 Inner Scan), using segmental bioelectrical impedance analysis & multi-frequency bioelectrical impedance analysis. Height was measured with a digital height measurer. Body mass index (BMI) was calculated as body weight (km) divided by the square of height (m). The results for the validity of regression polynomials of body fat percentage against BMI showed that, for both boys and girls, first-order polynomials were valid in all school years. With regard to changes with age in BMI and body fat percentage, the results showed a temporary drop at 9 years in the aging distance curve in boys, followed by an increasing trend. Peaks were seen in the velocity curve at 9.7 and 11.9 years, but the MPV was presumed to be at 11.9 years. Among girls, a decreasing trend was seen in the aging distance curve, which was opposite to the changes in the aging distance curve for body fat percentage.

    Background Given that it is not feasible to use dual x-ray absorptiometry (DXA) or other reference methods to measure adiposity in all pediatric clinical and research settings, it is important to identify reasonable alternatives. Therefore, we sought to determine the extent to which other adiposity measures were correlated with DXA fat mass in school-aged children. Methods In 1110 children aged 6.5-10.9 years in the pre-birth cohort Project Viva, we calculated Spearman correlation coefficients between DXA (n=875) and other adiposity measures including body mass index (BMI), skinfold thickness, circumferences, and bioimpedance. We also computed correlations between lean body mass measures. Results 50.0% of the children were female and 36.5% were non-white. Mean (SD) BMI was 17.2 (3.1) and total fat mass by DXA was 7.5 (3.9) kg. DXA total fat mass was highly correlated with BMI (rs=0.83), bioimpedance total fat (rs=0.87), and sum of skinfolds (rs=0.90), and DXA trunk fat was highly correlated with waist circumference (rs=0.79). Correlations of BMI with other adiposity indices were high, e.g., with waist circumference (rs=0.86) and sum of subscapular plus triceps skinfolds (rs=0.79). DXA fat-free mass and bioimpedance fat-free mass were highly correlated (rs=0.94). Conclusions In school-aged children, BMI, sum of skinfolds, and other adiposity measures were strongly correlated with DXA fat mass. Although these measurement methods have limitations, BMI and skinfolds are adequate surrogate measures of relative adiposity in children when DXA is not practical. PMID:23799991

    Consumption of sugar-sweetened beverages (SSB) has been associated with risk of obesity, but little evidence exists to evaluate if age of introduction and cumulative SSB consumption increases risk in children. The objective of the study was to estimate the relationship between age of introduction and cumulative SSB consumption with risk of obesity in 227 Mexican children. SSB intake was measured every 6 months; age of introduction and cumulative consumption during the pre-school period were calculated. Height, weight, waist circumference, SSB intake and other relevant variables were measured at age 8-14 years and obesity defined using standard criteria. All participants were introduced to SSB before age 24 months and most (73%) before 12 months. Early SSB introduction (≤12 months) was not significantly associated with increased odds of obesity (odds ratio [OR] = 2.00, 95% confidence interval [CI]: 0.87, 4.59). However, children in the highest tertile of cumulative SSB consumption, compared with the lowest, had almost three times the odds of general (OR = 2.99, 95% CI: 1.27, 7.00) and abdominal (OR = 2.70, 95% CI: 1.03, 7.03) obesity at age 8-14 years. High SSB consumption increased the likelihood of obesity in 8-14-year-old children. Our results suggest that SSB intake should be delayed and excessive SSB consumption in pre-school period should be avoided. © 2015 World Obesity.

The sample of girls consisted of 305 girls aged 7-11 that were not engaged in organized physical activities, as well as 300 girls engaged in the program of development gymnastics. According to decimal years, the girls were divided into four age groups within range of one calendar year. The test Raven’s Progressive Matrices in Color was applied for assessment of intellectual functioning with an aim to determine intellectual abilities of the two groups of girls. Results of chisquare test indicated statistically significant differences between the two groups of subjects in age groups of 8-9 and 9-10 applying a more relaxed criterion of statistical conclusion (p=0.05. Analyzing the distribution of female subjects within three intellectual groups (below-average, average, and above-average, a lower number of girls included in the program of development gymnastics was observed in the category of below-average intellectual abilities, especially in the two oldest groups. In addition, in most age groups, a higher number of girls with average and above-average intellectual abilities were observed among those engaged in the program of development gymnastics. According to the results of this research, authors concluded that successful practice of development gymnastics requires at least average intellectual abilities of younger school girls.

    The nutrition transition promotes the development of childhood obesity. Currently, Mexico is affected by this serious public health problem. The nutritional and functional characterization of a whole menu has a number of advantages over the study of single nutrients. Since breakfast is considered the most important meal of the day, this study aimed to evaluate the metabolite profile produced by in vitro human colonic fermentation of the isolated indigestible fraction (IF) from three different Mexican breakfast (M-B) menus (Modified "MM-B", traditional "TM-B", and alternative "AM-B"), previously identified as commonly consumed by Mexican schoolchildren in Nayarit State, Mexico. The M-B's consist of egg, corn tortilla, beans (higher in TM-B), sugar and chocolate powder (higher in AM-B) and milk, combined in different proportions. The IF in all breakfasts was about 4.7-5.6g/100g FW, with a relatively high content of protein (≈21%), which might have negative physiological implications. Fermentation of IF from TM-B resulted in the largest pH decrease after 72h (pH=6.07), with a low short chain fatty acid (SCFA) production (0.75 to 47.23mmol/L), but greater relative concentration of other fatty acids (FA) (C7, C8, C9). Besides, 55 volatile compounds were detected in the fermentation media by SPME-GC-MS and three principal components (PC) were identified. PC1 was influenced by SCFA production, low FA esters production (<8C), and low volatile organic acids production. PC2 was influenced by the decrease in pH and an increase in antioxidant capacity (p<0.0001). These results suggest that the production of different metabolites in the luminal medium may affect the pH and antioxidant status in the colon. Fermentation of IF from TM-M, assessed after 48 and 72h, showed the highest correlation for PC2; the metabolic pattern registered for this IF maybe considered beneficial.

    The objective of this review is to present an overview of some of the most commonly consumed artisanal Mexican cheeses, as well as those cheeses that show potential for a protected designation of origin. A description is given for each of these cheeses, including information on their distinguishing characteristics that makes some of them potential candidates for achieving a protected designation of origin status. This distinction could help to expand their frontiers and allow them to become better known and appreciated in other parts of the world. Due to the scarcity of scientific studies concerning artisanal Mexican cheeses, which would ultimately aid in the standardization of manufacturing processes and in the establishment of regulations related to their production, more than 40 varieties of artisanal cheese are in danger of disappearing. To preserve these cheeses, it is necessary to address this challenge by working jointly with government, artisanal cheesemaking organizations, industry, academics, and commercial partners on the implementation of strategies to protect and preserve their artisanal means of production. With sufficient information, official Mexican regulations could be established that would encompass and regulate the manufacture of Mexican artisanal cheeses. Finally, as many Mexican artisanal cheeses are produced from raw milk, more scientific studies are required to show the role of the lactic acid bacteria and their antagonistic effect on pathogenic microorganisms during aging following cheese making.

    Objective Nocturnal enuresis is a common psychosocial concern for both parents and children. In the present study we have determined the prevalence of nocturnal enuresis in Urmia, Iran children and associated personal and familial factors with this problem. Methods A cross sectional epidemiological study for detection of nocturnal enuresis prevalence rate and evaluation of associated familial and personal factors in elementary school children (7-11 years old) from Urmia were investigated. The subjects were selected by cluster sampling method. Chi square test and logistic regression were used in univariate and multivariate respectively. Findings Of the 1600 questionnaires distributed, 918 (57%) were completed and included in the final analysis. The rest, which were not filled by parents and also those out of our study age range were excluded. Gender of the subjects was almost equally distributed (48.6% males and 51.4% females). Prevalence of nocturnal enuresis was 18.7% (n = 172) and prevalence of day time incontinence was 5.5% (n=51). There was no significant gender difference between these two groups. Enuretics had crowded families, positive family history, low educational level of parents, jobless father, working mother, single parent, poor school performance, positive history of urinary tract infection (UTI). Conclusion Our results with enuresis prevalence and associated factors were comparable to other epidemiological studies from various countries. We found that Iranian families do not pay sufficient attention to their enuretic children. PMID:23550208

    This study was carried out to determine the internet use and psychosocial health of school aged children. Children in grades 4-7 and their parents were invited to participate. The study group consisted of 737 children. Data were collected using a descriptive form and Pediatric Symptom Checklist-17. Majority of children used internet, one of each five children had psychosocial problem risk. Risk of psychosocial problem was higher in males, children who have 'not working father', use internet 5 years and over, use internet for 3h and over per day. These results suggest that families should be informed about associations between internet use and psychosocial problems that measures should be taken for providing controlled internet use for children.

    In Jyväskylä Longitudinal Study of Dyslexia, we have investigated neurocognitive processes related to phonology and other risk factors of later reading problems. Here we review studies in which we have investigated whether dyslexic children with familial risk background would show atypical auditory/speech processing at birth, at six months and later before school and at school age as measured by brain event-related potentials (ERPs), and how infant ERPs are related to later pre-reading cognitive skills and literacy outcome. One half of the children came from families with at least one dyslexic parent (the at-risk group), while the other half belonged to the control group without any familial background of dyslexia. Early ERPs were correlated to kindergarten age phonological processing and letter-naming skills as well as phoneme duration perception, reading and writing skills at school age. The correlations were, in general, more consistent among at-risk children. Those at-risk children who became poor readers also differed from typical readers in the infant ERP measures at the group level. ERPs measured before school and at the 3rd grade also differed between dyslexic and typical readers. Further, speech perception at behavioural level differed between dyslexic and typical readers, but not in all dyslexic readers. These findings suggest persisting developmental differences in the organization of the neural networks sub-serving auditory and speech perception, with cascading effects on later reading related skills, in children with familial background for dyslexia. However, atypical auditory/speech processing is not likely a sufficient reason by itself for dyslexia but rather one endophenotype or risk factor. Copyright © 2011. Published by Elsevier SAS.

The most common component was low HDL cholesterol, 83·3 % in women and 78·9 % in men. Prevalence was positively associated with age. In women, metabolic syndrome was inversely related to education level whereas in men it was positively associated with household food security and height, after adjustment. The metabolic risk score in children was inversely related to parental height, and positively associated with height-for-age and with having parents with the metabolic syndrome. Metabolic syndrome is highly prevalent in Mesoamerica. The burden of metabolic risk factors disproportionately affects women and children of lower socio-economic status and men of higher socio-economic status.

    Full Text Available BACKGROUND: The theory of relative age effect assumes that children and adolescents - athletes born at the beginning of the calendar year in sports competitions are more successful than those who were born in the later months of the same year. This percentage is based on advantage of fitness, morphological and psychological assumptions of the older athletes. AIM: The research objective of the present study was to verify the assumption of competitive success of older players in the elite boys and girls tennis groups in the older school age. METHODOLOGY: The data from groups of 13 year old boys and girls (13 years and 0 months to 13 years and 11 months were included into the analysis. These players were registered in the first one hundred ranking of International Tennis Federation (ITF according to the total number of ranking points in each year during the period 2007-2011 (500 boys, 500 girls. An ANOVA was used for analysis with a total ranking score as an indicator of competitive success with the age factor (12 levels = 12 months of birth (α = .05. The same analysis was used in sub-groups of boys, respectively girls, registered in ITF separately for each year of the period 2007-2011. Dates of birth of children were obtained from official sources of ITF. In the event of the significance factor of age we performed a simple regression analysis depending on the number of ITF points on the month of birth (p < .05. Analyses were processed in SPSS 21 software (IBM, USA. RESULTS: The analysis showed no significance of age, respective of the month of birth on the total number of points in a boys group (n = 500 (p = .624 and girls group (n = 500 (p = .152 from ITF ranking during five-year period. No significance was found in the boys' groups (n = 100, respective girls' groups (n = 100 registered in ITF ranking in each year of the five-year period.

    2017-01-01

    Multitasking requires individuals to allocate their cognitive resources across different tasks. The purpose of the current study was to assess school-age children's multitasking abilities during degraded speech recognition. Children (8 to 12 years old) completed a dual-task paradigm including a sentence recognition (primary) task containing speech that was either unprocessed or noise-band vocoded with 8, 6, or 4 spectral channels and a visual monitoring (secondary) task. Children's accuracy and reaction time on the visual monitoring task was quantified during the dual-task paradigm in each condition of the primary task and compared with single-task performance. Children experienced dual-task costs in the 6- and 4-channel conditions of the primary speech recognition task with decreased accuracy on the visual monitoring task relative to baseline performance. In all conditions, children's dual-task performance on the visual monitoring task was strongly predicted by their single-task (baseline) performance on the task. Results suggest that children's proficiency with the secondary task contributes to the magnitude of dual-task costs while multitasking during degraded speech recognition.

    Parental monitoring has been described as a protective factor and useful strategy to prevent substance misuse among youths. The aim of this study was to examine whether perceived parental monitoring influences frequency of alcohol use, age of drinking onset and risky drinking among entering public high school and university students in Mexico City. The study is a cross-sectional survey of entering first year students in the high school and university school system of a large public university in Mexico City conducted during registration at the beginning of the school year. In 2008, of 34,840 students accepted to the affiliated high schools, 28,996 students (51.8% female) completed the alcohol survey and of 37,683 students accepted into university 30,084 students (51.5% female) completed the alcohol survey. The findings suggest that compared to students with higher perceived parental monitoring those reporting lower perceived parental monitoring were more likely to report risky behavior. They were more likely to be ever drinkers, frequent drinkers, have earlier age of onset and high AUDIT scores. Overall, higher parental monitoring was strongly associated with being female and lower parental monitoring with being male. Our findings suggest that more research on parental monitoring as a protective strategy against alcohol misuse is needed. Research focusing on cultural factors including gender and age-related norms and familismo would increase knowledge of the association of parental monitoring and alcohol use among Mexican youths, Mexican American youths and potentially youths from other Hispanic backgrounds.

  20. The age of school shootings: a sociological interpretation on masculinity

    Directory of Open Access Journals (Sweden)

    Celis, Jorge

    2015-01-01

    Full Text Available Over the past two decades there has been a growing interest in the study of the horrendous massacres perpetrated by students at school premises. These massacres, known as school shootings, haven been predominantly analyzed by employing psychological approaches. Despite the fact that empirical research clearly reveals that school shooters tend not to present life-long histories of mental illness, these approaches usually put a strong emphasis on the perpetrator’s individual pathologies, ignoring the influence that social values such as masculinity exert on perpetrators’ actions. Consequently, perpetrators are viewed as lone wolf shooters and school shootings as isolated cases. Based on data derived from scholarly works published mainly in peer-review journals and the sociological theory of P. Berger and T. Luckmann, the aim of this essay is to offer a sociological interpretation on school shootings by explaining why school shooters commit violent actions against teachers and classmates as a form of retrieving their masculinity. In this regard, the essay finds that male rather than female students commit school shootings. At the same time, the majority of perpetrators have had parents who were gun collectors. It is no coincide that shooters mostly use family guns to commit the massacres. Additionally, shooters see school as a social entity that has diminished their masculinity, and the way to reaffirm their masculinity is to attack randomly students and teachers in full view of the rest of school members during school hours.

    During a health supervision visit, the father of a 7.5-year-old African American second-grader asked about his son's progress in reading. He was concerned when, at a recent teacher-parent conference to review Darren's progress, the teacher remarked that Darren was not keeping up with reading skills compared with others in his class. She said that he had difficulty sounding out some words correctly. In addition, he could not recall words he had read the day before. The teacher commented that Darren was a gregarious, friendly child with better-than-average verbal communication skills. His achievement at math was age-appropriate; spelling, however, was difficult for Darren, with many deleted letters and reversals of written letters. A focused history did not reveal any risk factors for a learning problem in the prenatal or perinatal periods. Early motor, language, and social milestones were achieved on time. Darren had not experienced any head injury, loss of consciousness, or chronic medical illness. He had several friends, and his father denied any behavioral problems at home or at school. His teacher completed a DSM-IV-specific behavioral survey for attention-deficit/hyperactivity disorder (ADHD). It did not show any evidence of ADHD. Darren's father completed 1 year of college and is currently the manager of a neighborhood convenience store. His mother had a high school education; she recalled that she found it difficult to complete assignments that required reading or writing. She is employed as a waitress. Darren does not have any siblings. The pediatrician performed a complete physical examination, the results of which were normal, including visual acuity, audiometry, and a neurological examination. It was noted that Darren seemed to pause several times in response to questions or commands. On two occasions, during finger-nose testing and a request to assess tandem gait, directions required repetition. Overall, he was pleasant and seemed to enjoy the visit. His

To assess the validity of our tools, we tested the relations among the School-Age Assessment of Attachment, the Family Drawing and children's risk status. We used the Dynamic-Maturational Model of Attachment and Adaptation to interpret the assessments in the hope of identifying a gradient of risk, and explore whether a new coding method improved the validity of Family Drawings and their utility as a tool to complement the School-Age Assessment of Attachment. The participants were 89 children, aged between 5 and 12 years; 32 children were involved with mental health services or child protection. Each child completed a School-Age Assessment of Attachment and a Family Drawing. Both assessments differentiated between clinical and normative referrals with moderate effect sizes when dichotomizing risk versus non-risk attachment. When the analysis incorporated a gradient of six attachment classifications, the effect sizes decreased, but specificity of risk increased. The School-Age Assessment of Attachment had greater validity for discriminating risk, and type of risk, than the Family Drawings. With a School-Age Assessment of Attachment and family history, the Family Drawing can provide information about distress that some children do not provide verbally. Integration of the two assessment tools alongside information about parental and family functioning appears to be the key to formulating children's problems.

    Introduction Prevention programs have not achieved the expected results in preventing mortality from breast and cervical cancer in Mexico. Therefore, we propose a complementary strategy. Methodology An educational strategy for high school students in Mexico (2011–2013) was designed (longitudinal design, two measurements and a single intervention). The postintervention assessment included: 1) knowledge acquired by students about cancer prevention and 2) The performance of the student as a health promoter in their household. The strategy was based on analysis of cases and developed in three sessions. An assessment tool was designed and validated (Test–Retest). The levels of knowledge according to the qualifications expected by chance were determined. Wilcoxon test compared results before and after intervention. Results An assessment instrument with 0.80 reliability was obtained. 831 high school students were analyzed. Wilcoxon rank-sum test showed a significant learning after the intervention (Z = − 2.64, p = 0.008) with improvement of levels of knowledge in a 154.5%. 49% of students had a good performance as health promoters. Conclusions The learning in preventive measures is important to sensitize individuals to prevention campaigns against cancer. This strategy proved to improve the level of knowledge of students in an easy and affordable way. PMID:26844079

    Full Text Available Mental health disorders are prevalent in children in all societies. The onset of most mental disorders is in youth (12–24 years of age, but most of the time they are first detected later in life. Poor mental health is strongly related to other health and development concerns so it is common to show high grade of stress, substance use, violence, and depression. The effectiveness of some interventions has been strongly established, although more researches are needed to improve the range of affordable and feasible interventions. The shortage of educational and fiscal policies and the fairly low attention to this subject is the main challenge addressing mental-health needs. Therefore, universal or early intervention programs are needed to develop protective factors by increasing competence or skills, to reduce existing negative behaviors. Moreover child discipline problems can be reduced by school multicomponent intervention strategies and as a result promotion in student’s achievement becomes evident.

    Full Text Available Resumen:El objetivo del presente estudio consiste en identificar la manera en que se reorganizaron los Centros de Atención Múltiple para atender los retos implícitos en la integración educativa y cómo valoran dichos cambios los integrantes de la comunidad educativa. Los cambios en la legislación que se realizaron en México con motivo del inicio de la integración educativa abarcaban a la educación especial en su conjunto. Con respecto a las escuelas de educación especial (ahora Centros de Atención Múltiple, CAMs, se mencionó que incorporarían sólo a alumnos con discapacidades muy severas, difíciles de atender en la educación regular; además, se señaló que, en la medida de lo posible, facilitarían la integración de los alumnos a las escuelas regulares en el corto o mediano plazos. Se realizó un estudio cualitativo en cu atro CAMs urbanos en la región central de México. Se aplicaron entrevistas a cuatro directores, doce integrantes del equipo multidisciplinario, once docentes y doce madres de familia, quienes participaron en el estudio de manera informada y voluntaria. Los resultados muestran que estos CAMs han seguido diferentes trayectorias desde que se inició la integración educativa. Dos de ellos realizaron cambios estructurales incorporando hasta cierto punto los nuevos lineamientos de la integración educativa, mientras que los otros funcionan como las antiguas escuelas de educación especial, con cambios superficiales. En general, los directores, docentes y especialistas tienden a valorar de manera negativa los cambios y a cuestionar su fundamento técnico, por lo que se puede afirmar que es una reforma fallida.Abstract:The purpose of the present study is to identify the changes performed by the Centers for Multip le Attention – CAMs - in order to address the challenges of inclusive education and to determine if these changes produced inclusive practices.

    Dyslipidemia often affects overweight and obese adolescents and can be present along with hypertension, insulin resistance, type 2 diabetes, and polycystic ovarian syndrome. This article is the third of six discussing the comorbidities of childhood obesity and will focus on the individual parts of the lipid profile and the impact of dyslipidemia on the heart and other body systems. Since few pharmacologic therapies are approved to treat dyslipidemia in children and adolescents younger than 18, treatment consists of lifestyle changes that can be supported and modeled by the school nurse. The school nurse can also be an advocate for a healthy lifestyle in the school district and community. More success in the treatment of dyslipidemia will be realized with less attention to changing the individual and more attention to changing the wider populations, including schools and the community. © 2015 The Author(s).

    We conducted a cross-sectional study among 1,717 children and adolescents of Mexican origin ages 5-19 years living in Mexico and Texas to explore the influence of country of birth and country of longest residence on their overweight and obesity status. Descriptive statistics were used to compare demographic and anthropometric characteristics of participants born and raised in Mexico (Mexicans), born in Mexico and raised in the United States (Mexican immigrants), and born and raised in the United States (Mexican-Americans). Univariate and multivariate nominal logistic regression was used to determine the demographic predictors of obesity adjusted by country of birth, country of residence, age, and gender. Almost half (48.8%) of the Mexican-Americans and 43.2% of the Mexican immigrants had body mass index at the 85th percentile or above, compared to only 29.3% of the Mexicans (P obese than their Mexican peers [Mexican-Americans: odds ratio (OR) = 2.5 (95% confidence interval [CI] 1.8-3.4); Mexican immigrants: OR = 2.2 (95% CI 1.6-3.0)]. In addition, males were more likely than females to be obese [OR = 1.6 (95% CI 1.2-2.1)], and adolescents 15-19 years of age were less likely than their younger counterparts [OR = 0.5 (95% CI 0.4-0.7)] to be obese. The high prevalence of obesity among children of Mexican origin in the United States is of great concern and underscores the urgent need to develop and implement obesity preventive interventions targeting younger children of Mexican origin, especially newly arrived immigrant children. In addition, future obesity research should take into consideration the country of origin of the study population to develop more culturally specific obesity interventions.

    As a result of the accelerated growth of the elderly population, reconfiguration of families and member roles, and the increase of mental disorders, it is necessary to investigate the effects of this set of factors on the caregivers of patients with dementia in Mexico. Mental disorders of individuals have a negative impact on their physical and emotional quality of life, leading to greater dependence and making the caring experience a heavy burden. Several studies (none in Mexico) have used either the characteristics of the patient or caregiver to determine the burden, but few studies have included both profiles within a single study. The objective of the present study was to analyze the characteristics of the patients and caregivers associated with caregiver burden. A multicenter study was carried out in six health institutions located in Mexico City, including 175 patients (and their caregivers) diagnosed with different types of dementia. We used the Spanish Caregiver Burden Screen. Descriptive analysis and logistic regressions were used to estimate the effect of the covariates on the caregiver burden. The results showed that patient variables have a greater impact on caregiver burden than caregiver-associated variables. Dysexecutive syndrome, sleep disorders, schooling and caregiver depression are associated with a higher level of caregiver burden. Caregiver burden is a complex phenomenon. The results of the present study showed the need to implement multifactorial interventions targeting the caregiver to reduce the burden, strengthen the skills for patient management to avoid depression, improve patient health, and diminish functional dependence and future hospitalization. © 2013 Japan Geriatrics Society.

  3. Introduction to the Special Issue on Normal Neuropsychological Development in the School-Age Years.

    2001-01-01

    In neuropsychological research on normal development relatively little interest has been devoted to age-related changes in school age. This is surprising in light of the significance of the changes that take place in this period of life, the availability of normative data, and the ongoing research on neural development. The studies included in this issue take a closer look at normative data from school-age children of various ages in performances of attention, language, sensorimotor functions, perceptual functions, memory and learning, and functional asymmetries. A finding evident in many of the studies is that age effects seem to be more accentuated below 9 to 10 years than after that age. It is hoped that this special issue will draw attention to the scarcity of data in this realm and to the possibilities of utilizing existing databases for study on normal development in school age.

    2010-01-01

    Full Text Available Instruction of Italian language at primary school level has not been studied more comprehensively in our expert and scientific literature so far, since Italian has been studied as a compulsory foreign language in Serbian schools since the school year 2001/2002. This paper discusses some peculiarities of learning and teaching a foreign language, with emphasis on the socio-cultural aspect and functional usage of the language as the primary task of instruction. The paper presents the results of one part of a larger empirical research that studies the attitude of primary school students towards learning Italian as a foreign language. The goal of the research refers to identifying the competences that students acquire by learning this language and the possibility of applying the linguistic knowledge and skills in real-life situations of students' interaction with the members of other culture, as well as identifying learning difficulties. The sample comprised 185 fifth grade students and 110 seventh grade students from three primary schools where the Italian language has been studied the longest. Research findings indicate that there is an initial positive attitude towards learning Italian and the sensitivity for extralinguistic and cultural elements of instruction of foreign language. Students pointed out to the need for a more active participation in instruction and selection of teaching contents, for more modern approaches to learning, and for a larger degree of applicability of linguistic knowledge and skills in real-life situations.

    Full Text Available Abstract Background In Mexico, as in other developing countries, micronutrient deficiencies are common in infants between 6 and 24 months of age and are an important public health problem. The objective of this study was to determine the prevalence of anemia and of iron, folic acid, and zinc deficiencies in Mexican children under 2 years of age who use the health care services provided by the Mexican Institute for Social Security (IMSS. Methods A nationwide survey was conducted with a representative sample of children younger than 2 years of age, beneficiaries, and users of health care services provided by IMSS through its regular regimen (located in urban populations and its Oportunidades program (services offered in rural areas. A subsample of 4,955 clinically healthy children was studied to determine their micronutrient status. A venous blood sample was drawn to determine hemoglobin, serum ferritin, percent of transferrin saturation, zinc, and folic acid. Descriptive statistics include point estimates and 95% confidence intervals for the sample and projections for the larger population from which the sample was drawn. Results Twenty percent of children younger than 2 years of age had anemia, and 27.8% (rural to 32.6% (urban had iron deficiency; more than 50% of anemia was not associated with low ferritin concentrations. Iron stores were more depleted as age increased. Low serum zinc and folic acid deficiencies were 28% and 10%, respectively, in the urban areas, and 13% and 8%, respectively, in rural areas. The prevalence of simultaneous iron and zinc deficiencies was 9.2% and 2.7% in urban and rural areas. Children with anemia have higher percentages of folic acid deficiency than children with normal iron status. Conclusion Iron and zinc deficiencies constitute the principal micronutrient deficiencies in Mexican children younger than 2 years old who use the health care services provided by IMSS. Anemia not associated with low ferritin values

    This study aimed to examine the association between child development at 5 years of age and mathematics ability and schooling outcomes at 12 years of age in Malawian children. A prospective cohort study looking at 609 rural Malawian children. Outcome measures were percentage of correctly answered mathematics questions, highest school grade completed and number of times repeating school grades at 12 years of age. A child development summary score obtained at 5 years of age was the main exposure variable. Regression analyses were used to estimate the association and adjust for confounders. Sensitivity analysis was performed by handling losses to follow-up with multiple imputation (MI) method. The summary score was positively associated with percentage of correctly answered mathematics questions (p = 0.057; p = 0.031 MI) and with highest school grade completed (p = 0.096; p = 0.070 MI), and negatively associated with number of times repeating school grades (p = 0.834; p = 0.339 MI). Fine motor score at 5 years was independently associated with the mathematic score (p = 0.032; p = 0.011 MI). The association between child development and mathematics ability did not depend on school attendance. Child development at 5 years of age showed signs of positive association with mathematics ability and possibly with highest school grade completed at 12 years of age. © 2012 The Author(s)/Acta Paediatrica © 2012 Foundation Acta Paediatrica.

    Full Text Available The study was designed to examine the school age experiences of university students, specifically the roles their school teachers, parents, and they themselves played in their preparation for higher education. One thousand students from twenty universities were randomly selected. Data collected through developed questionnaire was tabulated, analysed and discussed. Chi Square was applied to determine whether the observed frequencies were significantly different from the expected frequencies. Main conclusions of study were that the students negated the role of school teachers, student self, peers and school environment with the preparation skills needed for university level work, while only parents’ role was found significant in preparing students for higher education.

    Associations of the strength of school smoking policies with cigarette, e-cigarette and cannabis use in Wales were examined. Nationally representative cross-sectional survey of pupils aged 11-16 years (N=7376) in Wales. Senior management team members from 67 schools completed questionnaires about school smoking policies, substance use education and tobacco cessation initiatives. Multi-level, logistic regression analyses investigated self-reported cigarette, e-cigarette and cannabis use, for all students and those aged 15-16 years. Prevalence of current smoking, e-cigarette use and cannabis use in the past month were 5.3%, 11.5% and 2.9%, respectively. Of schools that provided details about smoking policies (66/67), 39.4% were strong (written policy applied to everyone in all locations), 43.9% were moderate (written policy not applied to everyone in all locations) and 16.7% had no written policy. There was no evidence of an association of school smoking policies with pupils' tobacco or e-cigarette use. However, students from schools with a moderate policy [OR = 0.47; 95% (confidence interval) CI: 0.26-0.84] were less likely to have used cannabis in the past month compared to schools with no written policy. This trend was stronger for students aged 15-16 years (moderate policy: OR = 0.42; 95% CI: 0.22-0.80; strong policy: OR = 0.45; 95% CI: 0.23-0.87). School smoking policies may exert less influence on young people's smoking behaviours than they did during times of higher adolescent smoking prevalence. Longitudinal studies are needed to examine the potential influence of school smoking policies on cannabis use and mechanisms explaining this association. © The Author 2016.

    Characterization of academic functioning in children with autism spectrum disorder (ASD), particularly predictors of achievement, may have important implications for intervention. The current study aimed to characterize achievement profiles, confirm associations between academic ability and concurrent intellectual and social skills, and explore preschool predictors of school-age academic achievement in a sample of children with ASD. Children with ASD (n = 26) were evaluated at the approximate ages of two, four, and ten. Multiple regression was used to predict school-age academic achievement in reading and mathematics from both concurrent (i.e. school-age) and preschool variables. Children with ASD demonstrated a weakness in reading comprehension relative to word reading. There was a smaller difference between mathematics skills; math reasoning was lower than numerical operations, but this did not quite reach trend level significance. Concurrent IQ and social skills were associated with school-age academic achievement across domains. Preschool verbal abilities significantly predicted school-age reading comprehension, above and beyond concurrent IQ, and early motor functioning predicted later math skills. Specific developmental features of early ASD predict specific aspects of school-age achievement. Early intervention targeting language and motor skills may improve later achievement in this population.

    Full Text Available The study examined age and gender differences in aggression using three representative samples for Slovenia: 4th grade elementary school students; 8th grade elementary school students; 4th grade secondary school students in Matura programs. The results were based on the LA aggression scale that measures general aggression and four specific types of aggression: physical aggression (TA, verbal aggression (BA, internal aggression (NA and aggression towards authority (AA. Based on the results of two-way ANOVA we found important effects of age, gender and their interaction. The gender differences were significant in the groups of elementary school students but not in secondary school students. Male elementary school students, 4th and 8th grade, were more aggressive compared to female elementary school students. 8th grade elementary school students were more physically, verbally, internally aggressive and more aggressive towards authority when compared to 4th grade elementary school students. Secondary school students were significantly less physically and verbally aggressive, and on the other hand more internally aggressive when compared to both groups of elementary school students. Secondary school students reported higher level of aggression towards authority than 4th grade elementary students, and lower level then 8th grade elementary students. The results were congruent with the findings of the research literature indicating higher aggression of males when compared to females and different developmental paths for different types of aggression in question. The study introduced important findings regarding age and gender differences in representative school samples in Slovenia and proposed future research mostly in direction of including measures of indirect aggression that is linked to female gender and older students.

    School-age children have attracted relatively little attention as a group in need of special measures to protect them against malaria. However, increasing success in lowering the level of malaria transmission in many previously highly endemic areas will result in children acquiring immunity to malaria later in life than has been the case in the past. Thus, it can be anticipated that in the coming years there will be an increase in the incidence of both uncomplicated and severe malaria in school-age children in many previously highly endemic areas. In this review, which focuses primarily on Africa, recent data on the prevalence of malaria parasitaemia and on the incidence of clinical malaria in African school-age children are presented and evidence that malaria adversely effects school performance is reviewed. Long-lasting insecticide treated bednets (LLIN) are an effective method of malaria control but several studies have shown that school-age children use LLINs less frequently than other population groups. Antimalarial drugs are being used in different ways to control malaria in school-age children including screening and treatment and intermittent preventive treatment. Some studies of chemoprevention in school-age children have shown reductions in anaemia and improved school performance but this has not been the case in all trials and more research is needed to identify the situations in which chemoprevention is likely to be most effective and, in these situations, which type of intervention should be used. In the longer term, malaria vaccines may have an important role in protecting this important section of the community from malaria. Regardless of the control approach selected, it is important this is incorporated into the overall programme of measures being undertaken to enhance the health of African school-age children. © 2014 The Authors.

    We describe the frequency and variations in bullying among a representative national sample of school-age children and examine whether sociodemographic characteristics are associated with bullying. This study is based on a cross-sectional school-based survey-the Icelandic contribution to the international research network Health Behaviour in School-aged Children (HBSC). The study population included all students in Iceland in grades 6, 8 and 10 (mean ages: 11, 13 and 15years, respectively) (participation rate: 84%; n=11,018). The students completed an anonymous standardized questionnaire administered in the classroom. The self-reported frequency of being victimized by bullying at least 2-3 times every month was 5.5%. A younger age, speaking a foreign language at home, not living with one's parents, and living in a rural area, were all associated with higher frequencies of being bullied. Despite efforts to reduce bullying in school, experiences of being victimized through bullying are still too common among Icelandic school-age children. Stakeholders and school health administrators should consider sociodemographic antecedents when planning interventions to reduce bullying at school. Copyright © 2017 Elsevier Inc.

    Drug use among older adults is a growing concern, particularly for the burgeoning Hispanic population. Older adults seeking drug treatment will double over the next decade to almost 6 million. Cultural factors influence drug use, and more specifically, Hispanic cultural values influence heroin use. This study explored Mexican-American injection drug users' adherence to traditional Hispanic cultural values and their impact on cessation. Ethnographic interviews endorsed contextualized influences of values on heroin use. Cultural values functioned dichotomously, influencing both initiation and cessation. Understanding the impact of cultural values on substance abuse is critical given the changing demographics in American society.

    Childhood obesity is associated with a number of metabolic abnormalities leading to increased cardiovascular risk. Metabolites can be useful as early biomarkers and new targets to promote early intervention beginning in school age. Thus, we aimed to identify metabolomic profiles associated with obesity and obesity-related metabolic traits. We used data from the Obesity Research Study for Mexican children (ORSMEC) in Mexico City and included a case control (n = 1120), cross-sectional (n = 554) and a longitudinal study (n = 301) of 6-12-year-old children. Forty-two metabolites were measured using electrospray MS/MS and multivariate regression models were used to test associations of metabolomic profiles with anthropometric, clinical and biochemical parameters. Principal component analysis showed a serum amino acid signature composed of arginine, leucine/isoleucine, phenylalanine, tyrosine, valine and proline significantly associated with obesity (OR = 1.57; 95%CI 1.45-1.69, P = 3.84 × 10(-31)) and serum triglycerides (TG) (β = 0.067, P = 4.5 × 10(-21)). These associations were validated in the cross-sectional study (P < 0.0001). In the longitudinal cohort, the amino acid signature was associated with serum TG and with the risk of hypertriglyceridemia after 2 years (OR = 1.19; 95%CI 1.03-1.39, P = 0.016). This study shows that an amino acid signature significantly associated with childhood obesity, is an independent risk factor of future hypertriglyceridemia in children.

    Children in the school-aged period are those most likely to sustain a fractured femur. One method of treatment for this age group is immobilization of the fracture in 90/90 traction. Specific needs of these children are discussed, and related nursing problems are identified. The physiologic and psychosocial aspects of nursing care are also addressed. Emphasis is placed on the developmental tasks inherent in this age group. Mastery of illness and hospitalization are central issues for the school-aged child and can be facilitated through the efforts of nursing and hospital staff. A therapeutic play program is also a beneficial adjunct to treatment and nursing care.

    The study was done to identify toddlers who have an increased risk of developing dental decay at school age. Six variables-Cariostat score, mother's ethnicity, evidence of baby bottle tooth decay, mother;s dental health status, toddler's age at first tooth, and frequency of brushing - showed a significant association with decay status at school age with odds ratios ranging from 1.89 to 2.63. The Cariostat score and the frequency of brushing remained significant in a logistic regression. No interaction terms were significant. The Cariostat caries activity test would be a useful screening tool for identifying toddlers most likely to develop decay or could be used periodically as the deciduous molars erupt and become colonized with oral bacteria. The findings confirm that good oral hygiene practices can have an impact on future dental health, and caregivers should be encouraged to brush young children's teeth regularly.

    To study the annual incidence of injuries and the relationship between behavior problems and injuries among school-age children. A prospective cohort study on injuries for 1-year follow-up period was conducted among 2 005 school-age children selected by cluster sampling from three primary schools in Maanshan city. They subjects were divided into two groups with or without exposure according to behavior problems rated by the Rutter Child Behavior Questionnaire at the beginning of the study. Nonparametric test was performed to analyze the differences in injuries between the two groups of children, and the influential factors for injuries were analyzed with multi-classification ordinal response variable logistic regression model. The overall incidence rate for injuries in school-age children was 42.51%, while among children with and without behavior problems were 64.87% and 38.85%, respectively. There were significant differences between the two groups (u = -6.054, P = 0.000). However, the incidence rates of injuries in school-age children with antisocial (A) behavior, neurotic (N) behavior and mixed (M) behavior were 66.99%, 67.41% and 61.40%, respectively. No significant differences were found among them (u(A,N) = -0.052, P = 0.958; u(A,M) = -0.400, P = 0.689; u(N,M) = -0.364, P = 0.716). Multivariate analysis indicated that injuries in school-age children were associated with children behavior problems, maternal age at childbirth, bad conditions during mother pregnancy, education background of mother, prevention measures for safety at home and the child accompanied to travel between school and home by adults. Behavior problems of children seemed to be the major risk factors for injuries. Children with behavior problems represented a significant risk group for injuries among school-age children. When planning intervention strategies on injuries, behavior problems should be emphasized to ensure optimal effectiveness of intervention.

    Full Text Available Average paternal age is increasing in many high income countries, but the implications of this demographic shift for child health and welfare are poorly understood. There is equivocal evidence that children of older fathers are at increased risk of neurodevelopmental disorders and reduced IQ. We therefore report here on the relationship between paternal age and a composite indicator of scholastic achievement during adolescence, i.e. compulsory school leaving grades, among recent birth cohorts in Stockholm County where delayed paternity is notably common. We performed a record-linkage study comprising all individuals in Stockholm County who finished 9 years of compulsory school from 2000 through 2007 (n = 155,875. Data on school leaving grades and parental characteristics were retrieved from administrative and health service registers and analyzed using multiple linear regression. Advancing paternal age at birth was not associated with a decrease in school leaving grades in adolescent offspring. After adjustment for year of graduation, maternal age and parental education, country of birth and parental mental health service use, offspring of fathers aged 50 years or older had on average 0.3 (95% CI -3.8, 4.4 points higher grades than those of fathers aged 30-34 years. In conclusion, advancing paternal age is not associated with poorer school performance in adolescence. Adverse effects of delayed paternity on offspring cognitive function, if any, may be counterbalanced by other potential advantages for children born to older fathers.

    Full Text Available Anxiety is defined as a multidimensional response with emotional, cognitive, behavioral, and physiological domain with the anticipation of threat. Anxiety negatively interferes with the adaptive functioning of students in elementary and secondary schools and needs to be investigated in detail. The present article examines age and gender differences in representative samples of elementary (4th and 8th grade students and secondary school students (students of 4th grade in Matura programs. The LAOM anxiety scale that measures anxiety with its components (emotional and cognitive in students in schools was used. Based on the results of two-way ANOVA important age, gender and the interaction effect is evident in analyzed data. 8th grade female students are more anxious compared to 8th grade male students. The gender differences in 4th grade elementary sample and secondary school sample were not significant. 8th grade students are more anxious compared to 4th grade students, secondary school students are least anxious compared to both elementary school samples. The results are congruent with the findings of the research literature indicating higher anxiety of females when compared to males and higher anxiety of older students when compared to younger students. The paper offers important findings regarding age and gender differences in representative school samples in Slovenia and proposes future research in direction of including different age groups and different measures of anxiety in the analyses.

Mexican heritage residents (N=1,791) of the city of Brownsville, TX, aged 18 years or older, enrolled in the Cameron County Hispanic Cohort, were selected through two stage cluster sampling of randomly selected census tracts from the first and third quartile of SES using Census 2000. Among current smokers, anxiety and depression scores were highest among women who had not completed high school (panxiety and depression than never smoking women. Negative affective states may represent a greater barrier to smoking cessation among women than men.

    Full Text Available The examination of primary school children to determine the ranking of significant factors that determine the structure of their functional state depending on the level of physical health. It is shown that the main factor in the structure of the functional state of younger schoolchildren in low-and lower-middle level of physical fitness is selected morpho-functional status, which characterizes the functions of the body at rest. For children with average or above average level of physical fitness is a leading factor in physical fitness of schoolchildren.

    Full Text Available School nutrition as a component of quality of life is analyzed. A total of 180 children 10–17 years old are examined. Health indicators studied in conjunction with physiological components of quality of life. The one-sided nutrition principles with predominance of cereals and confectionery products with low consumption of dairy and meat products are determined. The deficit of the fundamental components of nutrition creates a risk factor for health problems and makes preconditions for the development of somatic pathology

    The nutritional status of school-aged children impacts their health, cognition, and subsequently their educational achievement. The school is an opportune setting to provide health and nutrition services to disadvantaged children. Yet, school-aged children are not commonly included in health and nutrition surveys. An up-to-date overview of their nutritional status across the world is not available. To provide a summary of the recent data on the nutritional status of school-aged children in developing countries and countries in transition and identify issues of public health concern. A review of literature published from 2002 to 2009 on the nutritional status of children aged 6 to 12 years from Latin America, Africa, Asia, and the Eastern Mediterranean region was performed. Eligible studies determined the prevalence of micronutrient deficiencies or child under- and overnutrition using biochemical markers and internationally accepted growth references. A total of 369 studies from 76 different countries were included. The available data indicate that the nutritional status of school-aged children in the reviewed regions is considerably inadequate. Underweight and thinness were most prominent in populations from South-East Asia and Africa, whereas in Latin America the prevalence of underweight or thinness was generally below 10%. More than half of the studies on anemia reported moderate (> 20%) or severe (> 40%) prevalence of anemia. Prevalences of 20% to 30% were commonly reported for deficiencies of iron, iodine, zinc, and vitamin A. The prevalence of overweight was highest in Latin American countries (20% to 35%). In Africa, Asia, and the Eastern Mediterranean, the prevalence of overweight was generally below 15%. The available data indicate that malnutrition is a public health issue in school-aged children in developing countries and countries in transition. However, the available data, especially data on micronutrient status, are limited. These findings emphasize

    Mexican Americans are one of the largest and fastest growing ethnic groups in the United States, yet we have limited knowledge regarding changes (i.e., developmental trajectories) in cultural orientation based upon their exposure to the Mexican American and mainstream cultures. We examined the parallel trajectories of Mexican American and mainstream cultural values in a sample of 749 Mexican American adolescents (49 % female) across assessments during the fifth grade (approximately 11 years of age), the seventh grade (approximately 13 years of age) and the tenth grade (approximately 16 years of age). We expected that these values would change over this developmental period and this longitudinal approach is more appropriate than the often used median split classification to identify distinct types of acculturation. We found four distinct acculturation trajectory groups: two trajectory groups that were increasing slightly with age in the endorsement of mainstream cultural values, one of which was relatively stable in Mexican American cultural values while the other was declining in their endorsement of these values; and two trajectory groups that were declining substantially with age in their endorsement of mainstream cultural values, one of which was also declining in Mexican American cultural values and the other which was stable in these values. These four trajectory groups differed in expected ways on a number of theoretically related cultural variables, but were not highly consistent with the median split classifications. The findings highlight the need to utilize longitudinal data to examine the developmental changes of Mexican American individual's adaptation to the ethnic and mainstream culture in order to understand more fully the processes of acculturation and enculturation.

    This research examined how environmental attributes near intersections influence the perceived crash risk among school-aged children, which provides information on the potential risks of pedestrian crashes that can guide the development of proactive countermeasures. In a sample of 799 children aged 10-12 years old in Korea, the environmental attributes of intersections perceived as having a high risk of producing crashes near elementary schools were investigated using standard negative binomial and zero-inflated negative binomial models.The results showed that a higher number of student crossings, a wider road width, the presence of crosswalks, student-friendly facilities at the intersection, and four-way intersections were significant and positively associated with perceived crash risk among school-aged children. The findings related to building characteristics indicated that a higher number of entrances at an intersection increased the perceived crash risk while higher visibility at the intersection reduced the perception of risk. Associations with traffic-calming measures were weak,suggesting that the measures used in the study areas were not effective in reducing the perceived crash risk. The results of a police-reported crash model showed that school-aged children have a relatively accurate perception of crash risk and that the perceived crash risk of school-aged children may provide valuable information on the intersection characteristics in need of attention near school sites.

    To examine the association of gestational age with school readiness in kindergarten reading and math skills. We hypothesized that compared with infants born at 39-41 weeks, infants born at lower gestational ages would have poorer school readiness. The study sample comprised 5250 children from the Early Childhood Longitudinal Study, Birth Cohort, assessed with specialized reading and math assessments at kindergarten. Poor school readiness was characterized by reading and math theta scores ≥1.5 SD below the sample mean. The aOR and 95% CI of poor school readiness were estimated using multivariate logistic regression, examining gestational age continuously and categorically (very preterm [VPT], moderate/late preterm [M/LPT], early term [ET], and term). Pairwise comparisons were performed to test for differences by gestational age category. There was an association between gestational age and poor school readiness for reading and math, with the suggestion of a threshold effect in children born at ≥32 weeks gestation. In adjusted models, in VPT infants, the aORs of poor school readiness in reading and math were 2.58 (95% CI, 1.29-5.15) and 3.38 (95% CI, 1.66-6.91), respectively. For infants born M/LPT and ET, the odds of poor school readiness in reading did not differ from those of children born full-term, however. Compared with term infants, the highest odds of poor school readiness in reading and math were seen in VPT infants, with lower odds of poor school readiness in children born at ≥32 weeks gestation. Ongoing developmental surveillance before kindergarten is indicated for VPT infants. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available Abstract Background There is growing evidence that quality, rather that quantity of fat is the determinant of cardiovascular risk. The objective of the study is to describe quantitatively the intake and adequacy of fatty acid classes among the Mexican population aged 5-90 years from a probabilistic survey. Methods Dietary intake of individual and classes of fatty acids was computed from the dataset of the 2006 Mexican National Health and Nutrition Survey (ENSANUT2006, collected by a food frequency questionnaire. Adequacy was calculated in reference to authoritative recommendations. Results The mean intake of total fatty acids (TFA ≈ 25%E fell within WHO recommendations; the intakes of saturated fatty acids (SFA among all age-groups (45-60% and of trans fatty acids (TrFA in 30% of school-age children and adolescents and 20% of adults exceeded international recommendations. The mean intake of polyunsaturated fatty acids (PUFA and particularly of n6 and n3 PUFAS, was inadequately insufficient in 50% of the sample. Conclusions The main public health concerns are the high intake of SFA and the suboptimal intake of PUFA in Mexican population. The TrFA intake represents a low public health risk.

    Macdonald, Jacqui A; Beauchamp, Miriam H; Crigan, Judith A; Anderson, Peter J

    2014-01-01

    The transition to school is associated with a greater requirement to inhibit irrelevant or inappropriate thought and behavior in order to concentrate on effective learning and to interact successfully with peers. Current knowledge of inhibitory control development in the early school years is limited due to a lack of normative data from age-appropriate, sensitive measures. In this study, three pictorial versions of the Stroop task were administered to investigate inhibitory control development in early school-aged children. Age-related trajectories of inhibition and effects of gender were examined in 80 children (42 boys) aged 5 to 8 years. All children were assessed with the Cognitive Assessment System Expressive Attention subtest (Big-Small Stroop), Fruit Stroop, and Boy-Girl Stroop. The Big-Small Stroop revealed substantial age-related improvement in inhibition from 5 to 7 years with a levelling of performance at 8 years of age, while the Fruit Stroop and Boy-Girl Stroop demonstrated clear but nonsignificant age trends. In particular, older children committed fewer errors and corrected their errors more frequently than younger children. Performance on all Stroop tasks correlated significantly, providing evidence that they tap similar cognitive abilities. Some gender differences were found. This study indicates that inhibitory skills develop rapidly in the early school years and suggests that error awareness may be a useful indicator of the development of cognitive inhibition for this age group.

  5. Relative Age in School and Suicide among Young Individuals in Japan: A Regression Discontinuity Approach.

    Directory of Open Access Journals (Sweden)

    Tetsuya Matsubayashi

    Full Text Available Evidence collected in many parts of the world suggests that, compared to older students, students who are relatively younger at school entry tend to have worse academic performance and lower levels of income. This study examined how relative age in a grade affects suicide rates of adolescents and young adults between 15 and 25 years of age using data from Japan.We examined individual death records in the Vital Statistics of Japan from 1989 to 2010. In contrast to other countries, late entry to primary school is not allowed in Japan. We took advantage of the school entry cutoff date to implement a regression discontinuity (RD design, assuming that the timing of births around the school entry cutoff date was randomly determined and therefore that individuals who were born just before and after the cutoff date have similar baseline characteristics.We found that those who were born right before the school cutoff day and thus youngest in their cohort have higher mortality rates by suicide, compared to their peers who were born right after the cutoff date and thus older. We also found that those with relative age disadvantage tend to follow a different career path than those with relative age advantage, which may explain their higher suicide mortality rates.Relative age effects have broader consequences than was previously supposed. This study suggests that policy intervention that alleviates the relative age effect can be important.

    Smoking experimentation in Mexican American youth is problematic. In light of the research showing that preventing smoking experimentation is a valid strategy for smoking prevention, there is a need to identify Mexican American youth at high risk for experimentation. A prospective population-based cohort of 1,179 adolescents of Mexican descent was followed for 5 years starting in 2005-06. Participants completed a baseline interview at a home visit followed by three telephone interviews at intervals of approximately 6 months and additional interviews at two home visits in 2008-09 and 2010-11. The primary endpoint of interest in this study was smoking experimentation. Information about social, cultural, and behavioral factors (e.g., acculturation, susceptibility to experimentation, home characteristics, and household influences) was collected at baseline using validated questionnaires. Age, sex, cognitive susceptibility, household smoking behavior, peer influence, neighborhood influence, acculturation, work characteristics, positive outcome expectations, family cohesion, degree of tension, ability to concentrate, and school discipline were found to be associated with smoking experimentation. In a validation dataset, the proposed risk prediction model had an area under the receiver operating characteristic curve (AUC) of 0.719 (95% confidence interval, 0.637-0.801) for predicting absolute risk for smoking experimentation within 1 year. The proposed risk prediction model is able to quantify the risk of smoking experimentation in Mexican American adolescents. Accurately identifying Mexican American adolescents who are at higher risk for smoking experimentation who can be intervened will substantially reduce the incidence of smoking and thereby subsequent health risks. ©2014 American Association for Cancer Research.

    To determine the effectiveness of the nutritional supplement developed for the Oportunidades programme on growth, prevalence of anaemia, morbidity and cognitive function of pre-school children. In a randomised, placebo-controlled longitudinal trial, children were assigned to one of three experimental treatment groups: Oportunidades food supplement (OFS), powdered milk (PM) and placebo (PL). Treatments were administered daily for 6 months. Weight, height and Hb were measured in all participants before and after supplementation. Morbidity was assessed two times per week for 6 months using validated questionnaires. The Bayley Scale of Infant Development Test was administered at baseline and after 6 months. Three marginal rural communities of the state of Queretaro, Mexico. A total of 224 children, mean age 22·4 (SD 5·9) months, were recruited. After the 6-month intervention, 186 completed the study. No differences were found in the adjusted changes of weight, height or anaemia between treatment groups and PL. No differences were found in the number of episodes of gastrointestinal or respiratory disease, nor were there any differences in cognitive performance between treatment and PL groups after 6 months of supplementation. Daily supplementation of 12-24-month-old children with OFS has no additional benefits in growth, anaemia, morbidity or cognitive performance.

    Since the majority of schools are housed in buildings dating from the 1960s and 1970s, a comprehensive construction and renovation program of school buildings has been carried out to improve the educational conditions in Korea. However, classrooms and computer rooms, with pressed wood desks, chairs and furnishings, as well as construction materials, might have negative effects on the indoor air quality. Furthermore, most schools have naturally ventilated classrooms. The purpose of this study was to characterize the concentrations of different indoor air pollutants within Korean schools and to compare their indoor levels within schools according to the age of school buildings. Indoor and outdoor air samples of carbon monoxide (CO), carbon dioxide (CO(2)), particulate matter (PM(10)), total microbial count (TBC), total volatile organic compounds (TVOCs) and formaldehyde (HCHO) were obtained during summer, autumn and winter from three sites; a classroom, a laboratory and a computer classroom at 55 different schools. The selection of the schools was based on the number of years since the schools had been constructed. The problems causing indoor air pollution at the schools were chemicals emitted by building materials or furnishings, and insufficient ventilation rates. The I/O ratio for HCHO was 6.32 during the autumn, and the indoor HCHO concentrations (mean = 0.16 ppm) in schools constructed within 1 year were significantly higher than the Korean Indoor Air Standard, indicating that schools have indoor sources of HCHO. Therefore, increasing the ventilation rate by means of a mechanical system and the use of low-emission furnishings can play key roles in improving the indoor air quality within schools.

    The association between schooling and old age cognitive outcomes such as memory disorders is well documented but, because of the threat of reverse causation, controversy persists over whether education affects old age cognition. Changes in state compulsory schooling laws (CSL) are treated as natural experiments (instruments) for estimating the effect of education on memory and mental status among the elderly. Changes in CSL predict changes in average years of schooling completed by children who are affected by the new laws. These educational differences are presumably independent of innate individual characteristics such as IQ. CSL-induced changes in education were used to obtain instrumental variable (IV) estimates of education's effect on memory (n = 10,694) and mental status (n = 9751) for white, non-Hispanic US-born Health and Retirement Survey participants born between 1900 and 1947 who did not attend college. After adjustment for sex, birth year, state of birth and state characteristics, IV estimates of education's effect on memory were large and statistically significant. IV estimates for mental status had very wide confidence intervals, so it was not possible to draw meaningful conclusions about the effect of education on this outcome. Increases in mandatory schooling lead to improvements in performance on memory tests many decades after school completion. These analyses condition on individual states, so differences in memory outcomes associated with CSL changes cannot be attributed to differences between states. Although unmeasured state characteristics that changed contemporaneously with CSL might account for these results, unobserved genetic variation is unlikely to do so.

    Older Mexican Americans (MAs) have consistently scored lower on the Folstein Mini-Mental State Examination (MMSE) than older European Americans (EAs). These lower scores may arise from factors other than those traditionally posited (age and education). Thus, this study examined the association between acculturation and structural assimilation and MMSE-assessed cognitive impairment, taking into account education, income, and other contextual factors. Subjects were participants in the San Antonio Longitudinal Study of Aging, a community-based study of chronic disease and functional status in 457 older MAs and 376 older EAs. Scales were used to measure two dimensions of acculturation: (family attitude, cultural values) and structural assimilation (functional integration into the broader American society). Logistic regression was used to examine the association between age, sex, acculturation, and structural assimilation and MMSE scores suggestive of cognitive impairment (impairments (hearing and vision), structural assimilation, but neither dimension of acculturation, was significantly and negatively associated with MMSE-assessed cognitive impairment. Older MAs in the lowest structural assimilation stratum were 1.89 times as likely to have MMSE-assessed cognitive impairment as those in the highest. Age, education, and visual impairment were also independently associated with cognitive impairment. These findings highlight the need for geriatricians to take contextual factors (including age, education, and structural assimilation) into account when interpreting MMSE scores of MA patients.

    Research suggests that school-age children with disruptive behavior (DB) problems frequently demonstrate impaired social skills and experience rejection from peers, which plays a crucial role in the pathway to more serious antisocial behavior. A critical question is which DB problems in early childhood are prognostic of impaired social functioning in school-age children. This study examines the hypothesis that aggression in early childhood will be the more consistent predictor of compromised social functioning than inattentive, hyperactive-impulsive, or oppositional behavior. Participants included an ethnically diverse sample of 725 high-risk children from 3 geographically distinct areas followed from ages 2 to 8.5. Four latent growth models of DB from child ages 2 to 5, and potential interactions between dimensions, were used to predict latent parent and teacher ratings of school-age social dysfunction. Analyses were conducted in a multi-group format to examine potential differences between intervention and control group participants. Results showed that age 2 aggression was the DB problem most consistently associated with both parent- and teacher-rated social dysfunction for both groups. Early starting aggressive behavior may be particularly important for the early identification of children at risk for school-age social difficulties.

    Diet and physical activity (PA) are essential components of nutritional status. Adequate nutrition and an active lifestyle are key factors during childhood, because food habits track into adulthood. Children spend more time in school than in any other environment away from home. Studying the diet factors and patterns of PA that affect obesity risk in children during school hours and the complete school day can help identify opportunities to lower this risk. We directly measured the time children spent performing moderate to vigorous PA (MVPA) at school, compared the amount and intensity of PA during school hours with after-school hours, and tried to determine if diet behaviors and PA or inactivity were associated with excess weight and body fat. This cross-sectional study included 143 normal-weight (NLW) and 48 obese children aged 8-10 y. Diet data were obtained from two 24-h recalls. Body composition was measured by bioimpedance. Screen time and sports participation data were self-reported. NLW children drank/ate more dairy servings than the obese children, who consumed more fruit-flavored water than the NLW group. Consumption of soft drinks, sugar-added juices, and fresh juices was low in both groups. Children were less active during school hours than after school. MVPA was lower during school hours in the obese group than in the NLW group. Schools, parents, and authorities should be more involved in promoting strategies to improve the dietary habits and PA levels of school-aged children, because this group is not achieving the recommended level of daily MVPA.

    To survey the sleep habits (bedtime, wake time), sleep duration, and sleep problems in school-age children of China. From November to December, 2005, a total of 19,299 school-age children from 55 elementary schools of 9 cities entered the study by a cross-sectional survey. A parent-administered questionnaire and the Chinese version of the Children's Sleep Habits Questionnaire were applied to investigate children's sociodemographic characteristics and sleep behaviors, respectively. The mean sleep duration was 9 hours and 10 minutes (9:10, SD:48 min) during the weekdays and 9:48 (SD: 63 min) during the weekends. In about 71.4% and 41.8% school-aged children the sleep duration per day did not reach the lowest criterion of 10 hours recommended by the Ministry of Education of China during weekdays and weekends, respectively. Sleep problems were common with prevalence ranging from 14.5% for sleep-disordered breathing to 75.3% for daytime sleepiness. Parasomnia (chi(2) = 13.76, P sleep-disordered breathing (chi(2) = 119.83, P sleep anxiety was more prevalent in girls than in boys (chi(2) = 19.42, P sleep problems were significantly associated with age. Inadequate sleep duration and sleep problems prevail among school-age children, which indicates that children's sleep health may be a major public health concern in China.

    To evaluate the long-term predictive value of persistent/recurrent otitis media with effusion (OME) in infants in relation with hearing levels at (early) school age. A case-cohort study among a population-based sample of school-age children screened for hearing deficits. Schoolchildren (second grade, 5-6 years of age) in the city of Utrecht, the Netherlands, who failed the hearing screening test and a sample of children invited for this screening. History of otitis media (serosa and acute) was assessed using three sources of information: a self-completion questionnaire mailed to the parents; medical records of otolaryngology visits; data from the (Ewing) hearing screening test at 9 months of age. Children who failed the primary Ewing test and children with recurrent and or persistent OME in the first 2 years of life showed an increased risk of failing school audiometry compared to children without such an OME history (OR=1.6 and 2.3, respectively). In a logistic model, the results of the primary Ewing test and the frequency of acute otitis media, proved to be moderately predictive for the screening test result at school age. OME in infants is a prognostic factor for hearing performance in the early school years.

    Full Text Available This research explores the role of symbolization in educational activity in children of late preschool and early school age. The aim of the research was to compare the efficiency of using sign and symbolic means (i.e. schemes and models in the learning of some new content in preschool and early school age. The study involved 46 children of late preschool age from one of the Moscow kindergartens, 20 girls and 26 boys (M = 78 months; and 25 first grade students of one of the Moscow schools, 16 girls and 9 boys (M = 101 months. The study consisted of the following stages: carrying out tests of mental abilities and dividing the subjects into two subgroups within each age group (that is, two subgroups of preschool children and two subgroups of school children with equal levels of development of the explored abilities; conducting developmental lessons aimed at making the children familiar with phenomena characterizing phase transitions in states of aggregation of matter — with the help of symbolic means (in the experimental group or sign means (in the control group; carrying out a posttest, that is, measuring the level of development of the concepts of aggregate states in all subgroups. The outcomes of the research indicated that symbolization may actually be an effective means of constructing learning content both in preschool and in early school age.

    In April 2012, the Turkish national education system was modified, and the compulsory school age of entry (first grade) was redefined as a minimum of 60 months and a maximum of 66 months (replacing the former minimum criterion of 72 months). In this study, we hypothesized that students starting school before 72 months (the previous age standard for the first grade) may experience (1) a greater number of symptoms of attention deficit hyperactivity disorder (ADHD) and (2) lower functioning in social, behavioral, and academic domains. We performed a cross-sectional community-based study in the first and second grades of all primary schools (4356 students) located in the Kadıköy county of Istanbul, Turkey. Teachers completed Swanson, Nolan, and Pelham version IV and Conners' Teacher's report forms for symptoms of ADHD, the Perceived Competence Scale for functioning, and a sociodemographic questionnaire. Among first graders, the group that began primary school before the age of 72 months had a higher ADHD prevalence than both of the groups that began primary school between the ages of 72 to 77 months and 78 to 83 months (p age for the first and second grade students. The probability of displaying ADHD symptoms (and caseness) is greater among the "earlier" beginners, whereas the "conventional" classmates exhibited better academic, social, and behavioral functioning.

    Increased upper respiratory infection (URI) among children at the beginning of school year is well known to parents and pediatricians. However, this phenomenon is not well documented or characterized. Computerized datasets from a large health maintenance organization in Israel were used to calculate the weekly rates of URI among children 3-14 years old for the years 2007-2012. In addition, nasopharyngeal swabs were collected in 2010-2012 from children with URI symptoms and controls during school opening time. Swabs were tested by real-time polymerase chain reaction for the presence of respiratory viruses. Time-series analysis demonstrated a peak of URI in September each year. The peaks reached their height 2 weeks after school opening and returned to baseline within 4-7 weeks. The main 3 viruses detected both in URI patients and in healthy controls during the first weeks of school opening were rhinovirus, adenovirus and enterovirus. The detection rate of any respiratory virus, and of rhinovirus in particular, was significantly higher among cases than among controls (54% vs. 16%, P age and sex cases had 5.8 times more viral detection when compared with controls. Upper respiratory symptoms were significantly more prevalent among the virus-positive cases when compared with negative ones. Back-to-school illness consisting of URI has a distinct epidemiological pattern demonstrating a rapid rise peaking within 2 weeks of school opening and is associated predominantly with rhinovirus.
