<p>Objective: This study was conducted to identify lifestyles related to overweight among elementary school students by gender and developmental stages.</p><p>Methods: In this cross-sectional study, Fukushima Prefectural Board of Education conducted a self-completed questionnaire diet survey among 2,369 third and fifth graders in 19 public elementary schools in Fukushima Prefecture, Japan in June 2015. Body size and lifestyles by gender and grade were compared using chi-square tests. To examine lifestyles related to overweight, an adjusted logistic regression analysis was conducted by using body size as the dependent variable and lifestyle as the independent variable.</p><p>Results: A total of 2,168 students (1,011 third graders, 1,157 fifth graders) were analyzed (response rate: 91.5%). The rate of being overweight was higher in fifth graders than that in third graders (26.7%, 22.3%, p=0.016) and among fifth graders it was higher in boys than in girls (29.4%, 23.8%, p=0.032). Lifestyles that were positively related to overweight were eating fast in boys, having less breakfast in girls, having less breakfast in third graders, and eating fast and engaging in less exercise other than physical education class in fifth graders. In addition, spending a long time between dinner and bedtime was related to overweight in fifth grade girls.</p><p>Conclusion: Lifestyles related to overweight among elementary school students were different according to gender and developmental stages.
