Abstract Background Japan has experienced a low prevalence of childhood obesity. The Japanese nationwide school lunch program is suggested to have helped this phenomenon, but it has not been proven. Methods From official statistics, we combined annual data for 2006–15 about the prefecture-level school lunch coverage rate for public junior high school students and the prefecture-level nutritional indicators calculated by randomly selected age–sex groups of 13–15-year olds: the percentage of overweight, obese or underweight children, who are 20% heavier, 30% heavier or 20% lighter than the standard weight by sex, age and height; and mean body weight (kg) or height (cm). We estimated the impact of the school lunch coverage rate on the nutritional indicators in subsequent years, adjusting for the lagged dependent variable and dummies for prefecture, age and year. Results A 10 percentage point increase in the prefecture-level school lunch coverage rate significantly decreased the percentage of overweight (0.37%, 95% CI: 0.18–0.56) and obesity (0.23%, 0.10–0.37) in subsequent years among boys, but not among girls. No significant effect on the percentage of underweight or mean body weight/height was observed for either sex. Conclusions Appropriate nutritional intake through school lunch may be effective to reduce childhood obesity.

The perceptions concerning weight, dieting practices, and nutrition of 326 adolescent girls attending an upper middle-class parochial high school were studied in relation to their body weight. Underweight or overweight students were those with greater than 10% body weight differential for height. The high school students reported an exaggerated concern with obesity regardless of their body weight or nutrition knowledge. Underweight, normal weight, and overweight girls were dieting to lose weight and reported frequent self-weighing practices. As many as 51% (n = 60) of the underweight adolescents described themselves as extremely fearful of being overweight and 36% (n = 43) were preoccupied with body fat. A distorted perception of ideal body weight was documented, particularly among the underweight students; the greater the underestimation of perceived ideal body weight, the greater the actual deficit in ideal body weight for height of the students (r = .73; P < .001). Normal weight and overweight girls had better concordance between their actual and perceived ideal body weight for height. The frequency of bingeing and vomiting behaviors was similar among the three weight categories. The data suggest that fear of obesity and inappropriate eating behaviors are pervasive among adolescent girls regardless of body weight or nutrition knowledge.

ABSTRACT Purpose: to verify the association between self-perception of health, gender, age, economic status, quality of life, cultural aspects and contexts of violence in high school adolescents. Methods: an observational analytical cross-sectional study with a probabilistic sample composed of 386 high school students aged 15-19 years. The data collection was made in 16 public schools. Descriptive, bivariate and multivariate data analyses were made. Models with hierarchical entry of the blocks according to the level of determination established in the theoretical model were built, and for the evaluation of associations in the logistic regression models, the significance level of 5% was considered. The Odds Ratio and its respective confidence interval of 95% were used as a measure of the magnitude of the associations. Results: the data revealed that more than two-thirds of the participants reported a positive self-perception of health and, in the hierarchical multiple logistic regression model, to have own house, to practice any religion, and the quality of life remained associated with positive Self-perception of health. Conclusion: having their own house, practicing a given religion and having a better quality of life increased the chances of a positive self-perception of health.
