BACKGROUND: It is unclear whether participation in home-delivered meal programs similar to the Older Americans Act home-delivered meals program influence weight status among older adults with hypertension and/or hyperlipidemia. OBJECTIVE: To examine the influence of a home-delivered Dietary Approaches to Stop Hypertension (DASH) meal intervention on body mass index (BMI), energy consumed, and percent of energy needs consumed. DESIGN: A 1-year randomized control trial of home-delivered DASH meals and medical nutrition therapy conducted from 2003 through 2005. Participants who received DASH meals were compared with those who did not receive meals. Data were collected in participants' homes at baseline, 6 months, and 12 months. PARTICIPANTS/SETTING: The study sample was composed of 298 adults aged >60 years with hypertension and/or hyperlipidemia residing in a county in the southeastern part of North Carolina. INTERVENTION: Participants in the meals intervention group received seven frozen meals per week for 1 year. The meals were designed to meet one third of participants' energy and nutrient needs and to comply with the DASH diet. MAIN OUTCOME MEASURES: Change in BMI, energy consumed, and percent of energy needs consumed. STATISTICAL ANALYSES PERFORMED: Difference-in-differences models were used to estimate the effects of the meal intervention on BMI, energy consumed, and percent of daily energy needs consumed. Analyses were conducted among the full sample and by subgroup (ie, race, income, and baseline obesity status). RESULTS: In the full sample, receipt of meals did not have a significant effect on BMI, energy consumed, or percent of daily energy needs consumed. Among those living at or above the 165% poverty threshold, receipt of home-delivered meals was significantly associated with a decrease in energy consumed and, therefore, percent of daily energy needs consumed. CONCLUSIONS: Participation in a home-delivered DASH meal program did not lead to weight gain or weight loss in a group of mostly overweight or obese older adults with hypertension and/or hyperlidemia.
