NWQ-CS = Neighborhood Walking Questionnaire - Chinese version for Seniors; r = correlation coefficient; min = minutes; wk = week; PA = physical activity; MVPA = moderate-to-vigorous physical activity; LVPA = light-to-vigorous physical activity. Positively skewed variables were log-transformed. a p < .05; b p < .01; c p < .001
