a
Leisure-time activity score (ordinal score for quintiles) and pace of walking (ordinal score for pace <2, 2–3, and >3 mph) were combined into a single physical activity score ranging from 2–8
b
Participants were asked to rate “health in general” and answers were dichotomized into “good” (excellent, very good and good) and “not good” (fair and poor) for the purposes of this analysis.
