子の年齢と親の身体活動との関連：スポーツライフ・データ2020の二次分析

抄録

BACKGROUND： Childbirth and parenthood induce lessened parental physical activity; however, this period of inactivity remains undetermined. Moreover, few studies have evaluated males. OBJECTIVE：Consequently, in this cross-sectional study, we evaluated the sufficiency of the World Health Organization’s（WHO’s） 2020 guidelines on physical activity for adults, particularly focusing on their youngest child’s age. METHODS：Using the 2020 Sasakawa Sports Foundation Sports-Life Survey, 847 adults, residing with their children aged 0-17-years-old, were included in the analysis. The adults’ factors included age; body mass index; marital status; city size; number of children; age of the youngest child; occupation; highest level of education; annual household income; subjective health; and the Global Physical Activity Questionnaire score. We assessed whether the WHO guidelines had been met, examining the correlation thereof with the youngest child’s age, using multiple logistic regression analysis. RESULTS：Of the 847 adults, 433 and 414 were male and female, respectively. The odds ratios［95% confidence intervals］ for meeting the WHO guidelines were statistically significantly higher for male with children aged 6-8 - （2.99［1.46-6.11］）, 9-11 - （2.34［1.00-5.50］）, and 15-17-years-old（2.85［1.14-7.11］）, and for female with children aged 3-5 - （2.12［1.06-4.26］） and 6-8-years-old（2.71［1.17-6.29］）, compared to those living with children aged 0-2-years-old. Domain-specific analyses revealed no statistically significant correlations with any of the domains for male, and a statistically significant correlation with leisure time for female. CONCLUSION：The probability of meeting the WHO guidelines increased when the youngest child was aged 6-8-, 9-11-, and 15-17-years-old for male; and 3-5-and 6-8-years-old for female.
