A randomized trial of a diet and exercise intervention for overweight and obese women from economically disadvantaged neighborhoods: Sisters Taking Action for Real Success (STARS).

ABSTRACT:

Background

Lower socioeconomic status at both the individual and neighborhood level is associated with increased health risks. Weight loss can reduce this risk, but few high quality weight-loss studies target this population.

Objectives

STARS tests a culturally appropriate, group-based behavioral and social support intervention on body weight and waist circumference in women from financially disadvantaged neighborhoods.

Design

A stratified (by BMI) randomized trial. Randomization to group was generated by a random numbers table with allocation concealment by opaque envelopes.

Methods

Participants 25-50 years who had a BMI ? 25 kg/m(2) and a waist circumference ? 88 cm were recruited from 18 census tracts in Columbia, SC with high rates of poverty between November 2008 and November 2010. All participants received a dietary and exercise counseling session. Intervention participants then receive 16 theoretically-based and tailored weekly group sessions followed by 8 weeks of telephone maintenance counseling. Control participants receive 16 weekly health education mailings. Measurements correspond to baseline, post-group intervention, and post-telephone counseling, and for intervention participants, after a 12-week no-contact period. Measurement staff was blinded to group assignment.

Results

Participants (N=155; n=80 intervention, n=75 minimal intervention control) were primarily African American (86.5%) and averaged 38.9 years with a mean BMI of 40.1 kg/m(2) and waist circumference of 115.4 cm. Food insecurity was reported by 43% of participants.

Summary

STARS targets an underserved population with an innovative, tailored, and theoretically-grounded, group-based intervention followed by telephone maintenance. If effective, the approach has the potential to be feasible and cost-effective for community delivery.

Project description:BackgroundEnhancing physical activity in overweight and obese individuals is an important means to promote health in this target population. The Health Action Process Approach (HAPA), which was the theoretical framework of this study, focuses on individual self-regulation variables for successful health behavior change. One key self-regulation variable of this model is action control with its three subfacets awareness of intentions, self-monitoring and regulatory effort. The social context of individuals, however, is usually neglected in common health behavior change theories. In order to integrate social influences into the HAPA, this randomized controlled trial investigated the effectiveness of a dyadic conceptualization of action control for promoting physical activity.Methods/designThis protocol describes the design of a single-blind randomized controlled trial, which comprises four experimental groups: a dyadic action control group, an individual action control group and two control groups. Participants of this study are overweight or obese, heterosexual adult couples who intend to increase their physical activity. Blocking as means of a gender-balanced randomization is used to allocate couples to conditions and partners to either being the target person of the intervention or to the partner condition. The ecological momentary intervention takes place in the first 14 days after baseline assessment and is followed by another 14 days diary phase without intervention. Follow-ups are one month and six months later. Subsequent to the six-months follow-up another 14 days diary phase takes place.The main outcome measures are self-reported and accelerometer-assessed physical activity. Secondary outcome measures are Body Mass Index (BMI), aerobic fitness and habitual physical activity.DiscussionThis is the first study examining a dyadic action control intervention in comparison to an individual action control condition and two control groups applying a single-blind randomized control trial. Challenges with running couples studies as well as advantages and disadvantages of certain design-related decisions are discussed.
