Weight Management in Rural Communities
The goal of this study is to evaluate the effect of three weight management interventions
(group phone conference calls, individual phone calls, and enhanced usual care) on weight
across 18 months in overweight and obese adults recruited through and treated by rural
primary care clinics.
(group phone conference calls, individual phone calls, and enhanced usual care) on weight
across 18 months in overweight and obese adults recruited through and treated by rural
primary care clinics.
The rates of overweight/obesity are significantly higher among residents of rural areas
compared to their urban counterparts. Recent focus to provide whole-person health care
suggests that rural primary care clinics may provide an ideal setting for delivery of weight
management.
This study is a 3 group randomized trial to evaluate intervention delivery. The investigators
will randomize 200 overweight/obese adult residents of rural towns (town population < 50,000)
who obtain health care at primary care clinics to one of three groups for an 18 month trial
(6 month weight loss; 12 month weight maintenance).
Group 1) Group phone (GP)/Portion-Controlled Meals (PCM)
Group 2) Individual phone (IP)/PCM
Group 3) Enhanced usual care (EUC)/Conventional Diet (CD)
All participants will receive a progressive physical activity program. Physical activity will
progress from 45 min/wk in month 1 to 225 min/wk in month 4 and remain at 225 min/wk for the
duration of the 18 month study for Group 1 & 2. Physical activity will progress from 45
min/wk in month 1 to 150 min/wk in month 4 and remain at 150 min/wk for the duration of the
18 month study for Group 3.
Participants on the CD will be asked to consume a nutritionally balanced, reduced energy,
high volume, lower fat (fat= 20-30% energy) diet recommended by the Academy of Nutrition and
Dietetics and the USDA's MyPlate approach. Examples of meal plans consisting of suggested
servings of proteins, grains, fruits and vegetables, dairy and fats based on individuals
energy needs will be provided. Participants using PCM will consume PCMs with the addition of
5 fruits and vegetables per day during weight loss.
EUC will meet with a health educator every 6 months to discuss weight management topics. GP &
IP will receive the weight management intervention over the phone weekly during weight loss
and biweekly during weight maintenance tracking diet and physical activity and will submit
the results to a health educator prior to every meeting.
