Home Environment-Focused Intervention Improves Dietary Quality: A Secondary Analysis From the Healthy Homes/Healthy Families Randomized Trial.

OBJECTIVE: Estimate Healthy Homes/Healthy Families (HHHF) intervention efficacy for improving dietary quality. METHODS: Low-income overweight and obese women (n = 349) recruited from rural community health centers were randomized to receive HHHF, a 16-week home environment-focused coaching intervention or health education materials by mail. Healthy Eating Index-2010 scores were calculated from 2 24-hour dietary recalls collected at baseline and 6- and 12-month follow-up. RESULTS: HHHF participants reported greater improvements in Healthy Eating Index-2010 total scores at 6-month follow-up (+3.41 ± 13.43 intervention vs +2.02 ± 12.26 control; P =.009). Subcomponent analysis indicated greater consumption of total vegetables (P = .02) and greens and beans (P = .001), whole grains (P = .02) and reduced consumption of empty calories (P = .03). Standardized intervention effect sizes were 0.16 at 6 months and 0.13 at 12 months of follow-up. CONCLUSIONS AND IMPLICATIONS: The HHHF resulted in short-term improvements in dietary quality, although more research is needed to interpret the clinical significance of effect sizes of this magnitude.

Barriers to weight loss among community health center patients: qualitative insights from primary care providers.

BACKGROUND: Community Health Centers (CHCs) are important settings for obesity prevention and control. However, few studies have explored the barriers that CHC clinicians perceive their patients face in maintaining a healthy weight. METHODS: Semi-structured in-depth interviews were conducted with thirty physicians, physician assistants, and nurse practitioners recruited from four Community Health Centers (CHCs), located in a rural, southwestern region of the state of Georgia, US. Interviews were digitally recorded, transcribed verbatim, and thematically analyzed. RESULTS: Clinicians perceived that their patients face numerous individual, interpersonal, and community-level barriers to weight loss. Perceived individual-level barriers included interrelated aspects of poverty and limited motivation to lose weight. Perceived interpersonal barriers included social and cultural norms, such as positive associations with larger body sizes, negative associations with smaller body sizes, lack of awareness of obesity as a problem, and beliefs regarding hereditary or generational body types. Perceived community-level barriers included limited healthy food options and aspects of the local food culture in the Southern US. CONCLUSIONS: Clinicians perceived that their patients face barriers to weight loss at multiple levels of the social ecology, including individual, social, and environmental factors. Results may partly explain limited provision of weight counseling in CHCs and suggest opportunities for intervention.

Impact of Improving Home Environments on Energy Intake and Physical Activity: A Randomized Controlled Trial.

OBJECTIVES: We assessed the effectiveness of an intervention targeting home food and activity environments to reduce energy intake and increase physical activity among overweight and obese patients from 3 community health centers in rural Georgia. METHODS: We conducted a randomized controlled trial (n = 349) from 2011 to 2013, with follow-up at 6 and 12 months. Health coaches delivered the 16-week intervention by using tailored home environment profiles showing areas in need of improvement and positive aspects of the home environment, behavioral contracts for healthy actions, and mailed support materials. RESULTS: Participants were mostly African American women (84.8%), with a mean age of 50.2 years and a mean body mass index (weight in kilograms divided by the square of height in meters) of 38.3. Daily energy intake decreased more for the intervention than control group at 6 (-274 vs -69 kcal) and 12 months (-195 vs -76 kcal). We observed no change for either objective or self-reported physical activity. At 12 months, 82.6% of intervention participants had not gained weight compared with 71.4% of control participants. CONCLUSIONS: The intervention was effective in changing home environments and reducing energy intake.
