  1. Note. Asterisks signify significant post-hoc differences (Bonferroni corrected) between respondents in the target category and those without children. ANCOVAs controlled for age, body mass index, marital status, education, ethnicity, income adequacy, and self-rated health. All estimates rounded to one decimal point based on Statistics Canada’s rounding guidelines in order to avoid implying greater precision than actually exists. CI = Confidence interval. MVPA = moderate-to-vigorous physical activity.
