The aim of the present study was to compare the factors associated with sports participation in females with children and females with no children of similar age. We analyzed data from the National Sports-Life Survey 2018 in adults and potential correlates of sports participation (females with children: n=269, median: 38.0 years (1st-3rd quartiles: 34.0-42.0 years) and females with no children: n=181, 29.0 years (23.0-43.5 years)). Sports participation and associated factors including demographic, behavioral, and environment factors were assessed by questionnaire. After controlling for age and sociodemographic variables, the results of logistic regression indicated that only the highest sedentary behaviour on weekdays (Odds ratio (OR)=2.22 (95% confidential interval: 1.10-4.47), p=0.03) was significantly negatively correlated with sports participation. Moreover, the interactions between females with children or females with no children and each factor were examined. As a result, for females with no children, a parent at home (OR=0.27 (0.10-0.71), p=0.01), skipping breakfast (OR=3.48 (1.41-8.60), p=0.01) and the longest time spent doing housework and laundry (OR=0.20 (0.05-0.79), p=0.02) were significantly negatively correlated with sports participation. The availability of bicycle facilities (OR=2.45 (1.03-5.82), p=0.04) was also significantly positively correlated with sports participation. The findings of this study suggest that sports participation was related with less sedentary time in females, a parent at home, lifestyle, and neighborhood environment in females with no children. In conclusion, lifestyle changes such as reducing sitting time and breakfast consumption may be beneficial in promoting sports participation among females in the lower and middle age groups.
