Physical Activity Intervention for Osteoporosis Prevention in Black Older Adults

Abstract

BackgroundPhysical activity (PA) is one of the lifestyle behaviors considered important in osteoporosis prevention. This study examined the effect of the Revised Health Belief Model theory‐based education program on osteoporosis prevention. The PA component is reported here.Research methodA repeated measure, randomized, wait‐list control design with 6‐weekly education sessions was offered to 130 consented black older adults in community settings in South Florida. The two groups were evaluated on the effect of the program on changes in calcium intake and PA after the program. PA benefits/barriers were discussed and demonstrated along with nutrition topics. PA was measured using Physical Activity, Osteoporosis Self‐Efficacy and other questionnaires based on the constructs of the theory.ResultsA total of 110 (experimental 59, wait‐list 51) completed all assessments. Mean age was 70.15±10.44 yrs and 90.0% were female. Reported PA scores were not significantly different (p>.05, η2 =.02), however osteoporosis self‐efficacy scores indicated participants perceived they could change their behaviors to impact their health (p<.05, η2=.20).ConclusionThough a combined dietary and PA program was effective with an Asian group, this population has more resistance to change PA behavior. Further studies are needed to explore alternative strategies to improve PA in this minority group.Grant Funding Source: N/A
