a the estimates were obtained from the Cox proportional hazard regression model adjusting for the study covariates retained using the backward elimination approach (P < .20). The covariates retained in both models included age group, race/ethnicity, education, BMI group, marital status, and self-reported medical conditions on coronary heart disease, high cholesterol, diabetes, and walking difficulty score.
