PURPOSE: To assess the feasibility of a home-based, individually-tailored physical activity print (HIPP) intervention for African American women in the Deep South. METHODS: A pilot randomized trial of the HIPP intervention (n = 43) versus wellness contact control (n = 41) was conducted. Recruitment, retention, and adherence were examined, along with physical activity (7-Day PARs, accelerometers) and related psychosocial variables at baseline and 6 months. RESULTS: The sample included 84 overweight/obese African American women aged 50 to 69 in Birmingham, AL. Retention was high at 6 months (90%). Most participants reported being satisfied with the HIPP program and finding it helpful (91.67%). There were no significant between group differences in physical activity (p = 0.22); however, HIPP participants reported larger increases (mean +73.9 minutes/week, SD 90.9) in moderate intensity or greater physical activity from baseline to 6 months than the control group (+41.5, SD 64.4). The HIPP group also reported significantly greater improvements in physical activity goal-setting (p = 0.02) and enjoyment (p = 0.04) from baseline to 6 months than the control group. There were no other significant between group differences (6MWT, weight, physical activity planning, behavioral processes, stage of change); however, trends in the data for cognitive processes, self-efficacy, outcome expectations, and family support for physical activity indicated small improvements for HIPP participants (p > 0.05) and declines for control participants. Significant decreases in decisional balance (p = 0.01) and friend support (p = 0.03) from baseline to six months were observed in the control arm and not the intervention arm. CONCLUSION: The HIPP intervention has great potential as a low cost, high reach method for reducing physical activity-related health disparities. The lack of improvement in some domains may indicate that additional resources are needed to help this target population reach national guidelines.
