Purpose This study aimed 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-d physical activity recalls, accelerometers) and related psychosocial variables at baseline and 6 months.

Results The sample included 84 overweight/obese African American women 50–69 yr old 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 of +73.9 min·wk−1 (SD 90.9)) in moderate-intensity or greater physical activity from baseline to 6 months compared with the control group (+41.5 min·wk−1 (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 compared with the control group. There were no other significant between-group differences (6-min walk test, 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 6 months were observed in the control arm and not the intervention arm.

Conclusions 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.
