Much research has been conducted to improve food environment or an individual’s diet in low food access areas, but the influence of living in a low food access area on behavioral dietary intervention compliance is still unknown. The purpose of this study was to determine if food access within a residential area influenced a dietary intervention effect. SISTAS (Sistas Inspiring Sistas Through Activity and Support) is a 12-week dietary and physical activity intervention for obese African-American women living in South Carolina. Participants were randomly assigned to intervention (n=68) or control (n=48) group. Participants in the intervention group received 12 weekly nutrition and physical activity educational sessions. A single 24-hour dietary recall was collected at baseline and post-intervention (12 weeks). Low access areas were defined as census tracts with at least one third of the ...

Teleconference Support circumvents barriers such as transportation to participation but few evaluations have been reported about teleconference support.

While many reports have espoused its advantages, few investigations have focused on comparing CBPR-oriented recruitment and retention. Consequently, the purpose of this analysis was to report and compare two different CBPR approaches in two cancer prevention studies. We utilized frequencies and Chisquared tests to compare and contrast subject recruitment and retention for two studies that incorporated a randomized, controlled intervention design of a dietary and physical activity intervention among African Americans (AA). One study utilized a de-centralized approach to recruitment in which primary responsibility for recruitment was assigned to the general AA community of various church partners whereas the other incorporated a centralized approach to recruitment in which a single lay community individual was hired as research personnel to lead recruitment and intervention delivery. Both studies performed equally well for both recruitment and retention (75 and 88 % recruitment rates and 71 and 66 % retention rates) far exceeding those rates traditionally cited for cancer clinical trials (*5 %). The de-centralized approach to retention appeared to result in statistically greater retention for the control participants compared to the centralized approach (77 vs. 51 %, p \ 0.01). Consequently, both CBPR approaches appeared to greatly enhance recruitment and retention rates of AA populations. We further note lessons learned and challenges to consider for future research opportunities.
