Unadjusted means ± SD; MVPA: moderate-to-vigorous intensity physical activity; AA: African Americans; “Separated” category includes those who reported being separated, widowed, or divorced; indicates adjusted model which includes armband wear time and all other demographics factors identified in this table. Groups (e.g., males and females) within the same category (e.g., gender) that have dissimilar superscripts indicate that the categories are significantly different from one another ().
