Paternal and Maternal Support on Children's Weekday and Weekend Moderate-to-vigorous Physical Activity: a Cross-sectional Study

Abstract

Background: Most studies about parental support behaviors for physical activity (PA) on children’s moderate-to-vigorous intensity physical activity (MVPA) were conducted in developed countries, and most of them focused on mother’s or parent’s (with no differentiation between father’s or mother’s) support behaviors. Besides, children’s MVPA time interval was not differentiated adequately. This paper aimed at investigating the associations between paternal and maternal support behaviors for PA, and children’s MVPA on weekdays, weekends and the whole week in China.Methods: Cross-sectional data of 517 father-child dyads and 1,422 mother-child dyads were analyzed. Children’s consecutive 7-day PA diary were recorded to assess their MVPA time, and MVPA time on weekdays, weekends and the whole week were further calculated, respectively. Father or mother completed a questionnaire on their support behaviors for children’s PA. Multivariate logistic regression was conducted to investigate the independent effect of paternal and maternal support behaviors for PA on children’s meeting MVPA recommendation on weekdays, weekends and the whole week, respectively.Results: The proportion of children’s meeting MVPA recommendation on weekends (37.8%) was significantly lower than that on weekdays (62.8%). Higher paternal (OR[95%CI]:1.098[1.009,1.195]) and maternal (OR[95%CI]:1.076[1.021,1.134]) total scores of support behaviors for PA were associated with children’s higher odds of meeting MVPA recommendation on weekends, after controlling for covariates. Paternal sharing PA knowledge with child was significantly associated with children’s meeting MVPA recommendation on weekends (OR[95%CI]:1.319[1.055,1.649]), and marginally associated with children’s meeting MVPA recommendation on weekdays (OR[95%CI]:1.220[0.974,1.528], P=0.084) and on the whole week (OR[95%CI]:1.218[0.977,1.519], P=0.080). Maternal reserving PA time for child was associated with children’s higher likelihood of meeting MVPA recommendation on weekdays (OR[95%CI]:1.160[1.025,1.313]), weekends (OR[95%CI]:1.241[1.097,1.403]) and the whole week (OR[95%CI]:1.214[1.076,1.369]), respectively.Conclusions: On weekends, paternal and maternal total support behaviors for PA deserves more practices for promoting children’s MVPA. To promote children’s MVPA on weekdays, weekends and the whole week, father’s sharing PA knowledge with child and mother’s reserving PA time for child are recommended. Longitudinal researches are needed to verify the effect of paternal and maternal support behaviors on children’s MVPA.
