Abstract
Lifestyle habits seem interconnected and extant studies suggest that a lifestyle-related modification can impact other related behaviors. For instance, interventions targeting physical activity (PA) could potentially impact dietary patterns and quality. Therefore, we hypothesized that a web-based intervention to increase PA would lead to changes in diet quality without explicit dietary guidance. Our aim was to evaluate changes in diet quality, measured by the Healthy Eating Index 2020 (HEI-2020), following a 12-week web-based PA intervention in adults with obesity. The study consisted of secondary analysis of a 12-week pilot randomized controlled trial, wherein participants (N = 82) were randomized to the Physical Activity for The Heart (PATH) intervention group, which included workout videos and virtual coaching, or a wait-list control group. Diet quality was assessed at baseline and post-intervention using the HEI-2020 based on recalls collected through the Automated Self-Administered 24-h recall (ASA-24) system. Baseline characteristics were similar across groups. Both groups showed small improvements in HEI-2020 total scores after 12 wk (PATH: 65.11 vs. Control: 62.24). Stratification by moderate to vigorous physical activities increase (<60 min. vs. ≥60 min.) revealed greater improvements in specific HEI-2020 components in the ≥60 min group, though overall changes remained modest. The PA intervention led to small improvements in certain diet quality components, suggesting potential interconnectedness between PA and dietary habits. However, overall changes in HEI-2020 scores were modest. Future research with larger samples should explore the effects of PA intervention alone vs. combined with dietary guidance on diet quality in adults with obesity.
期刊介绍:
Behavioral Medicine is a multidisciplinary peer-reviewed journal, which fosters and promotes the exchange of knowledge and the advancement of theory in the field of behavioral medicine, including but not limited to understandings of disease prevention, health promotion, health disparities, identification of health risk factors, and interventions designed to reduce health risks, ameliorate health disparities, enhancing all aspects of health. The journal seeks to advance knowledge and theory in these domains in all segments of the population and across the lifespan, in local, national, and global contexts, and with an emphasis on the synergies that exist between biological, psychological, psychosocial, and structural factors as they related to these areas of study and across health states.
Behavioral Medicine publishes original empirical studies (experimental and observational research studies, quantitative and qualitative studies, evaluation studies) as well as clinical/case studies. The journal also publishes review articles, which provide systematic evaluations of the literature and propose alternative and innovative theoretical paradigms, as well as brief reports and responses to articles previously published in Behavioral Medicine.
