AbstractEngaging in physical activity (PA) has been proved to reduce the risk of developing cardiovascular diseases. In patients with peripheral arterial disease (PAD), diminished PA predicts high overall mortality. However, the extent of the association of participation in PA with PAD severity is unknown. Therefore, the overarching aim of this study was to investigate the association between PAD severity, PA levels and patterns using the Hispanic Community Health Study/Study of Latinos. This was a cross-sectional cohort study that included 495 participants with PAD and a total of 12,281 participants without PAD from the Hispanic Community Health Study/Study of Latinos database. The Global Physical Activity Questionnaire was administered to assess the time spent weekly in performing moderate-to-vigorous PA (MVPA) during work, leisure time, and transportation. The ankle-brachial index (ABI) was used to measure PAD. PA status was categorized on the basis of MVPA as follows: physically active and physically inactive to insufficient. In addition, all participants were classified as follows: those with normal ABI who were physically active, those with normal ABI but who were physically inactive, those with PAD but were physically active, and those with PAD who were physically inactive. Complex sample for regression models were used to investigate the association between PA and the severity of PAD. Of the participants, 235 (47.5%) were physically inactive to insufficient, and 260 participants (52.5%) engaged in at least 150 min/wk of MVPA, which is the recommended PA level according to the guidelines of World Health Organization. Compared with who were highly active, the participants who engaged in low PA were twice as likely to have moderately severe ABI and 4 times as likely to have severe ABI, after adjustment for the covariates (age, smoking status, and body mass index). Hispanic/Latino adults with sever PAD in the US showed pattern of physical inactivity. Findings of this study highlight the association between PA and severity of PAD. These findings highlight the necessity of interventions in increasing PA in these participants. Future studies are required to identify appropriate exercise regimens or home-based programs to help patients with severe PAD meet the current PA recommendations.Copyright © 2022 the Author(s).
