Background: Race/ethnic-specific physical activity patterns and biological responses to physical activity is one of the most understudied, yet critical aspects related to the development and adoption of physical activity recommendations. Methods: In this 6-month community walking intervention targeting African Americans, participants wore a pedometer and maintained a pedometer diary for the study duration. Outcome measures included height, weight, percent body fat, waist circumference, blood pressure, lipids and glucose. ANOVA, Pearson Correlations, and Kruskal-Wallis tests were used to examine changes in steps/day over each month of the intervention and explore associations among pedometer-determined physical activity and anthropometric/ biological change scores from month 1 to 6. Results: The 83 participants were primarily African American (98%) women (94%). There was a significant increase in the average step/day beginning with 6665 (SD = 3,396) during month 1 and increasing to 9232 (SD = 3670) steps/day during month 6 (F = 4.5, P < .0001). Associations among step counts and anthropometric/biological change scores were not significant. Conclusions: While this intervention resulted in significant increases in steps/day; it exemplifies that physical activity standards may be unachievable for some vulnerable, minority communities. Methodological considerations for exploring associations between changes in pedometer-determined step counts and anthropometric/biological outcomes are emphasized through this study.
The process of developing and implementing this CBPR walking intervention was considered successful as evidenced by the community's active contribution and participation in each phase of this research, the undertaking and application of basic research components, significant improvements in several anthropometric and biological values, and sustainability of the collaborative partnership.
Background:Limited research has been done on the compliance and acceptability of maintaining pedometer diaries for an extensive time frame in community-based interventions targeting minority populations. Methods: Community "coaches" led participants in a 6-month community-based walking intervention that included wearing pedometers and maintaining pedometer diaries for the study duration. Descriptive statistics and ANOVA tests were used to evaluate compliance rates for maintaining diaries and daily step counts. After the intervention, focus groups were used to explore opinions regarding pedometers. Audiotapes were transcribed and evaluated using systematic content analysis. Results: The 8 coaches and 75 enrolled walking participants were primarily African American (98%) women (94%). Overall, the group (N = 83) submitted 85% of all possible pedometer diaries and recorded 73% of all possible daily step counts. Walkinggroup members were significantly (P < .01) more compliant if their coach was also compliant. Identified benefits of wearing pedometers and maintaining diaries outnumbered the barriers. Participants were enthusiastic about wearing the pedometers and indicated that the weekly diaries provided a source of motivation. Conclusions: This research suggests pedometer diaries are a viable intervention tool and research method for community-based physical activity interventions targeting Afri-Zoellner, Avis-Williams, and Yadrick are with the Dept of Nutrition and Food Systems, University of Southern Mississippi, Hattiesburg, MS. Powers is with the can Americans and highlights the need for social support to promote pedometer diary compliance.
The goal of this study was to understand the unique needs and barriers to breast cancer control among African American women in the rural South. This population experiences barriers that surpass that of other minorities. Researchers conducted 6 focus groups to assess barriers of minority women in Mississippi toward breast cancer prevention and clinical trials. These women had little knowledge of treatment options and negative perceptions of screening and clinical trial participation. This research equips others to identify new health education strategies. Conclusions also provide insight into prevention for other minority populations, such as Latina, Asian, and American Indian women.
Directly involving community members in identifying health problems and solutions results in the development of interventions that are likely to have greater acceptability with the community.
