Several studies have reported on constipation in infants, young adults, and the elderly in Japan; however, there are not enough studies on female high school students. Therefore, we aimed to estimate the incidence of constipation and to identify factors associated with constipation in Japanese high school girls. A total of 906 high school girls answered a self-reported questionnaire. They were divided into three groups (non-constipation, semi-constipation, and constipation) based on the number of bowel movements per week, stool shape, incomplete stool sensation, the time required for bowel movement, and laxative use. Multivariable logistic regression analysis was performed with constipation as the dependent variable and lifestyle-related factors and confounders as independent variables. A total of 54.1% students were assigned to the non-constipation group and 12.9% to the constipation group. The matching rate between the objective defecation status and the subjective defecation status was 53.0%. The multivariable adjusted odds ratio (OR) and 95% confidence interval (95%CI) for the constipation group was significant among Profile of Mood States scores (OR： 1.03, 95%CI： 1.00-1.06), eating breakfast (OR： 0.51, 95%CI： 0.30-0.86), chewing (OR： 0.58, 95%CI： 0.34-0.99), and dietary variety scores (OR： 0.90, 95%CI： 0.82-1.00), respectively. Our findings suggest that high school girls need to acquire appropriate knowledge regarding constipation and practice healthy eating habits.
