Abstract
INTRODUCTION: excess body weight among adolescents is on the increase and has become a global public health challenge. It is likely to persist to adulthood, exposing to risk of developing chronic diseases. However, there is insufficient information on the prevalence of excess body weight and associated factors among adolescent girls in secondary schools in northern Tanzania. METHODS: this cross-sectional study involved 400 secondary school adolescent girls, selected by multi-stage cluster sampling. A self-administered questionnaire was used to gather information. Anthropometric measurements were taken and body mass index calculated. Descriptive statistics summarized the data. Logistic regression was used to model excess body weight resulting into adjusted odds ratios with their 95% confidence intervals and significant level was set at p-value<0.05. RESULTS: the proportion of adolescents with excess body weight (BMI >+1SD) was 23%. The majority (63%), reported unhealthy dietary habits while half (51.5%) of them had moderate level of knowledge on healthy eating. Compared to working as a civil servant, the odds of having excess body weight among girls whose mothers/female guardians were housewives was less by 60% (aOR=0.4, 95%CI: 0.2, 0.9). Furthermore, the odds of having excess body weight among adolescents eating unhealthy foods were almost six times higher compared to their peers on healthy diet (aOR=5.8, 95%CI: 2.9, 11.3). CONCLUSION: prevalence of excess body weight among adolescent girls in northern Tanzania is high. Unhealthy dietary habits and mother's/female guardian's occupation were significant correlates of excess body weight. We recommend platforms to inform adolescents on the importance of proper food intake and to advance knowledge on dangers of excessive weight gain as a strategy towards prevention of nutrition-related diseases.
