Abstract
Much evidence exists for the health benefits associated with individual movement behaviors, which include light-intensity physical activity (LPA), moderate-to-vigorous physical activity, sedentary behavior, and sleep. However, individual movement behaviors are codependent in nature and exist within a finite period of 24-hours, further underlying the importance of examining the integration of movement behaviors. Despite the absence of 24-hour movement guidelines in the U.S., the benefits of adhering to such guidelines outweigh the potential harms, such as with various levels of physical activity intensity. Moreover, many intervention studies focus on one individual movement behavior underscoring the need for studies to examine intervention effects on integrated movement behaviors. Thus, the primary purpose of this study was to examine the prevalence of adults meeting 24-hour movement guidelines and potentially correlated sociodemographic factors. The secondary purpose of this study was to investigate the effects of a Health Action Process Approach (HAPA)-informed text message intervention on movement behaviors. Participants at three large universities in the southeast region of the U.S. completed an online survey about their sociodemographic characteristics and movement behaviors. A subsample of undergraduate students who completed the baseline survey participated in a 6-week HAPA-informed text message study. Based on a final analytic sample of 1,430, 12.2% adhered to overall movement guidelines. Black (AOR = 0.29, 95% CI [0.11, 0.82]) and Hispanic/Latinx adults (AOR = 0.23, 95% CI [0.06, 0.97]) had lower odds of meeting overall guidelines. For the text message study, a significant time effect was found for sedentary behavior, F(4, 438) = 7.79, p < .001, ��2 = 0.08, and LPA, F(4, 438) = 7.27, p < .001, ��2 = 0.08. Relative to baseline, time spent in sedentary behavior decreased, and time spent in LPA increased at all time points, respectively. The proportion of adults adhering to overall movement guidelines in the southeast region of the U.S. is low. Associations between race/ethnicity and adherence to overall guidelines are evident. Messaging strategies to promote 24-hour movement guidelines should be developed and tailored to targeted groups. Future text message studies should include an initial one-on-one session and individualize text message frequency and delivery time.
