Notes. Results from zero-inflated negative binomial regression models adjusted for mother’s age and no. of child(ren) in the household. Income and education were modelled as continuous variables (i.e., linear terms) because this yielded a substantially better model fit than when the same variables were treated as categorical. eb = exponentiated value of regression coefficient; OR = odds ratio; CI = confidence intervals; p = p-value; ref = reference category; PA = physical activity; ONR/EF = other non-residents/extended family; MVPA = moderate to vigorous physical activity. a These models provide information on the direct effects of socio-economic indicators on mothers’ MVPA and the associations of potential mediators (Presence of a domestic helper; Other non-resident/extended family members, spouse and mother undertaking three types of household activities) with mother’s MVPA (Steps 4 of mediation analysis). Bold denotes p < 0.05.
