ABSTRACT To study the prevalence of stunting, underweight, overweight and obesity among adolescents in a predominantly rural district in north-west Russia, and to assess the agreement between the findings obtained using international and Russian criteria.
Cross-sectional study.
Body weight and height were measured in 1066 schoolchildren aged 14-17 years, and body mass index values were calculated. The prevalences of stunting, underweight, overweight/obesity and obesity were estimated according to the World Health Organization 2007 (WHO-2007), Centers for Disease Control and Prevention 2000 (CDC-2000), Russian and International Obesity Task Force (IOTF) criteria. Pearson's Chi-squared test and McNemar's test were used to compare categorical data. The agreement between estimates obtained using Russian and international criteria was assessed by Cohen's kappa.
The prevalence of stunting was 3.3%, 5.2% and 4.5% using the WHO-2007, CDC-2000 and Russian criteria, respectively. The prevalence of overweight/obesity was 10.3%, 8.6%, 8.6% and 9.0% as estimated using the WHO-2007, CDC-2000, Russian and IOTF criteria. The corresponding proportions for obesity were 4.7%, 2.6%, 2.3% and 2.0%, and for underweight were 3.6%, 3.1%, 2.3% and 1.8%. The Russian criteria led to lower estimates for the prevalence of overweight/obesity in boys but not in girls. The agreement between the estimates obtained using international and Russian criteria varied between 0.3 and 0.9 in boys and between 0.2 and 1.0 in girls.
The prevalence of stunting was higher in the study population than in most European countries, whereas the prevalences of underweight, overweight/obesity and obesity were lower. The choice of reference population considerably influences the prevalence estimates. Moreover, the agreement between the estimates varies by gender.

    ABSTRACT: Overweight and obesity prevalence among children is increasing globally. Health promoting school policy has been initiated in Thailand to tackle this problem. The schools that best conduct obesity management programs are rated as diamond level health promoting schools (DLHPS). However, the methods used by these schools and their efficacies have not been well-documented. This qualitative study aims to analyze the processes and activities used by four DLHPSs in obesity management programs. In-depth interviews were used to obtain information from school directors, teachers, and cooks, whereas focus group discussions were used for students. School-based obesity management programs have resulted from health promoting school policy and the increasing prevalence of overweight students. Teamwork has been a key strategy in program implementation. Policy diffusion and division of labor have been effected by school directors. A monitoring process is put in place to ensure program delivery. The most evident success factor in the present study has been intersectoral cooperation. Challenges have included confusion about the criteria in obtaining the DLHPS status, parental involvement, and students' resistance to consume vegetables and other healthy foods. From the student focus groups discussions, three activities were most valued: class health and nutrition learning; provision of healthy foods and drinks, together with removal of soft drinks and seasoning from the cafeteria; and exercise for health. Intersectoral cooperation is the key success factor for the operationality of DLHPS, especially in making healthy foods available and physical activity the norm, at school and home.

    ABSTRACT: To describe the prevalence of 'graded thinness' in children aged 11, 13 and 15 years in eleven developed countries and to identify trends in the prevalence of 'thinness' (BMI < 17 kg/m2 at age 18 years) by age and gender. Cross-sectional study using data collected through self-reported questionnaires. Data were taken from the 1997/1998, 2001/2002 and 2005/2006 surveys of the Health Behaviours in School-aged Children (HBSC) Study. Children and adolescents from ten European countries and the USA (n 158 000). Prevalence of grades 1, 2 and 3 of thinness was higher among 11-year-old students compared with the 13- and 15-year-olds in all countries. A higher prevalence of thinness was observed in girls than in boys. Since 1998 the prevalence of thinness decreased steadily in Czech boys and girls, while it increased for French girls. In the total European sample of females, thinness decreased from 1998 to 2006 (χ 2 for trend, P < 0·01). Age-adjusted logistic regression analysis showed that Czech boys and girls, and Flemish and American girls were less likely to be thin in 2006 than in 1998; while a noteworthy increment, even if borderline significant, was observed for French girls with a 41 % increase in the likelihood to be thin. Our findings suggest that thinness is an important overlooked phenomenon with wide variation in prevalence and trends across developed countries. It deserves further longitudinal studies in a multinational context that could increase the understanding of the factors associated with thinness and contribute to developing preventive and nutritional programmes targeted at controlling obesity and chronic diseases, while monitoring thinness.

    ABSTRACT: In the last two decades there has been an increase in the number of children who have increased body weight or become obese. This statement confirms the fact that the affected population of children are not only in developed countries, but also in those who have a lower economic standard. Therefore, strategies for prevention and treatment of obesity have become a top priority for public health Aim of this study was to determine whether there is a difference in the level of motor skills with regard to the level of nutrition. Based on the obtained result, it could be confirmed hypothesis of this study that girls of normal body weight had a significantly better motor skills of the students who were overweight or obese. For students who have a problem with obesity must be developed intervention programs with a view to immediately engage in regular physical exercise to reduce body weight.
