AbstractHeart disease (HD) claims the lives of more than 500,000 women each year. As women grow older, the risk for HD begins to rise and continues to rise with age. Hispanic women have been found to have higher rates of HD risk factors, which can be controlled with physical activity (PA), when compared with non-Hispanic whites. Interventions designed to promote PA in Hispanic women have shown varying effectiveness. Further, there has been little attention to the development of socially and culturally relevant interventions for this population, to promote or sustain PA. Given the lack of data on effective interventions, preliminary research is essential to develop and test effective and culturally relevant interventions.
This pilot project, Intervencion de Motivation Para Actividad Fisica (IMPACTO), or Motivational Intervention for PA, focused on the development and evaluation of a theory-based motivational intervention program to promote regular PA among older Hispanic women. The Wellness Motivation Theory (WMT) guided IMPACTO, grounded in formative research, partnership with community members, and strengths of community-based PA interventions with Hispanic women. A randomized experimental design with repeated measures was used. The intervention group received a 12 week intervention, while the Attention Control group received weekly newsletters over the same time period that focus on older adult health and safety issues.
The total sample included 55 Hispanic women aged 50 and above. A repeated measures analysis of variance resulted in statistically significant changes over time for social contextual resources, behavioral change process variables, and reduction in cardiovascular health outcomes, such as percent body fat and systolic/diastolic blood pressure. There were no statistically significant changes in mean metabolic equivalents (METs) or body mass index (BMI) changes over time between groups.
Results reinforce the motivational role of the self, and highlight the importance of understanding those dimensions of behavioral change processes that are relevant to cardiovascular risk reduction. The elements of the WMT may guide clinicians in the application of feasible and culturally-relevant strategies to promote PA consistent with individual values, goals, supports and resources.
