Learning and Developing Individual Exercise Skills (L.A.D.I.E.S.) for a Better Life: A Church-Based Physical Activity Intervention - Baseline Participant Characteristics.

ABSTRACT

OBJECTIVE: Physical activity (PA) is beneficial for health, yet most African American women do not achieve recommended levels. Successful, sustainable strategies could help to address disparities in health outcomes associated with low levels of PA. The Learning and Developing Individual Exercise Skills (L.A.D.I.E.S.) for a Better Life study compared a faith-based and a secular intervention for increasing PA with a self-guided control group. DESIGN SETTING AND PARTICIPANTS: This cluster randomized, controlled trial was conducted from 2010 - 2011 in African American churches (n=31) in suburban North Carolina. Participants were 469 self-identified low active African American women. MEASURES: Baseline data were collected on participant demographics, objective and self-reported PA, and constructs related to social ecological theory and social cognitive theory. RESULTS: Complete baseline data were available for 417 participants who were aged 51.4 ± 12.9 years, with average BMI (kg/m2) 35.8 ± 9.9; 73% of participants were obese (BMI >30). Participants averaged 3,990 ± 1,828 pedometer-assessed daily steps and 23.9 ± 37.7 accelerometer-assessed minutes of daily moderate-to-vigorous PA, and self-reported 25.4 ± 45.4 minutes of weekly walking and moderate- and vigorous-intensity PA. Baseline self-reported religiosity and social support were high. CONCLUSIONS: L.A.D.I.E.S. is one of the largest PA trials focused on individual behavior change in African American women. Baseline characteristics suggest participants are representative of the general population. Findings from the study will contribute toward understanding appropriate strategies for increasing PA in high-risk populations.
