Prevalence of Obesity and the Factors Associated with Low Obesity Awareness among Urban Adolescents in Harare, Zimbabwe.

Obesity is a global health problem. In developing countries such as Zimbabwe, obesity is both an emerging health problem and a grey area, particularly among adolescents. This study assessed the prevalence of obesity and factors associated with low obesity awareness among adolescents. METHOD: A cross-sectional survey was performed using an interviewer-administered questionnaire. The participants were 423 adolescents aged 14-19 years recruited from 10 schools in Harare using a stratified random sampling technique. Data were analyzed using SPSS software (version 23) and binary logistics regression was used to examine the factors associated with low obesity awareness. The level of significance was set at p < 0.05. RESULTS: The median± IQR age was 16 (14-18) years, and overweight and obesity affected 15.8% of the participants with higher proportions among girls (73.1%, p = 0.002). Low obesity awareness was observed in 27.1% of the adolescents with a higher proportion among girls (67.0%, p = 0.001), 14-16-year-olds (51.3%, p = 0.317), and obese adolescents (56.7%, p = 0.001). Significant factors associated with low obesity awareness were household heads lacking formal education [OR = 9.41 (2.20-40.36), p = 0.003] and inadequate (poor) food habits [OR = 2.58 (1.33-5.01), p = 0.005]. CONCLUSIONS: Our study showed that adolescents had different obesity awareness levels and diverse perceptions in terms of obesity causes, and a range of potential solutions. Obesity awareness and nutrition education should address adolescents' poor eating habits while taking cognizance of the different education levels of household heads.

The relationship between parental mealtime behavior and subjective diet-related quality of life (SDQOL) of Japanese adolescents: A cross sectional study in Kumamoto prefecture.

BACKGROUND AND OBJECTIVES: Family meals favor adolescent dietary quality and mental health. The aim of this study was to explores the relationships between parental behavior during family meals, and the subjective dietrelated quality of life (SDQOL) of Japanese adolescents. METHODS AND STUDY DESIGN: Participants comprised 664 second-year junior high school students aged 13-14 years from Kumamoto Prefecture, Japan. Survey items included sex, age, family structure, parental behavior during mealtimes (frequency of warnings/listening to children), frequency of family meals (number of meals taken together), and SDQOL. Participants were divided into two groups (low and high) based on the median SDQOL score. Logistic regression analysis was performed to examine the relationships among parental behavior during meals, frequency of family meals, and SDQOL. The dependent variable was SDQOL; independent variables were parental mealtime behavior and family meal frequency. RESULTS: The high-SDQOL group comprised 150 boys (45.3%) and 167 girls (51.1%). Compared to those who ate with family 0-5.5 times per week, those who did so 7-9.5 (OR: 2.56, 95% CI: [1.64-4.00]) or 11.5-14.0 (OR: 2.87, 95% CI: [1.83-4.50]) times per week had a better SDQOL. Those whose parents listened during meals on four or more days per week, compared with three days or less, had a better SDQOL (OR: 4.06, 95% CI: [2.76- 5.98]). CONCLUSIONS: Eating together more than seven times a week and having parents listen to them during meals are associated with better adolescent SDQOL.

Associations of body-related teasing with weight status, body image, and dieting behavior among Japanese adolescents.

Background: Body-related teasing is known to be linked to body dissatisfaction and dieting behavior in adolescents. However, little is known about it in non-Western countries. This study aims to examine the prevalence of body-related teasing among Japanese adolescents and its connection to weight status, body image, and dieting behavior to consider implications for public health. Methods: The design of this study is a cross-sectional study. An anonymous self-administrated survey was conducted with 1172 junior high school students in Higashi-Osaka City in Osaka Prefecture in Japan. The sampling method was non-random design. The survey items included self-reported height and weight, history and source of teasing, body image perception, and dieting behavior. A chi-square test and logistic regression analysis were used to examine the associations. Results: A history of teasing was reported by 16.4% of boys and 32.5% of girls (P < 0.001, effect size = 0.19). The most common answer for source of teasing was friends (84.7% of boys' teasing, 67.1% of girls' teasing, P = 0.003, effect size = 0.19). Students who were overweight, of an upper-normal weight status, and perceived themselves as "fat" were at a greater risk of being teased. Additionally, students with a history of teasing were significantly likelier to display dieting behavior (odds ratios with confidence intervals: boys 4.06 [2.08-7.93], girls 2.40 [1.53- 3.75]). Conclusion: Body-related teasing has a significant association with body image and dieting behavior in Japanese adolescents. A school-based education should be provided to reduce body-related teasing.
