Legend: ^a = includes multi-racial. A significant regression equation was found for model 1: F(6,10) = 4.57 (model 1) with a p-value of 0.017. When adding household size (model 2), the regression equation was no longer significant: F(6,10) = 4.56 with a p-value of 0.078. When adding physical activity to model 1 (model 3), a significant regression equation was found: F(7,9) = 8.06, p-value: 0.003. Reference categories were as follows: Male sex; Non-Hispanic White; Household size: two persons. Moderate recreational activities in a typical week: “no”. OR = odds ratio. CI = confidence interval. The model is based on a total n of 5264 participants.
