당뇨병 치료제로서의 식품 (FAME-D)
음식은 약이다: 제2형 진성 당뇨병과 식량 불안정을 가진 개인을 위한 의학적으로 맞춤화된 식사의 무작위 임상 시험
The investigators propose a single-site, open-label, Phase II, community-based randomized clinical explanatory trial to test the efficacy of a medically tailored meal (MTM) interventions for adults with food insecurity and T2DM (Type 2 Diabetes Mellitus). While the efficacy of MTM needs to be established, given the nature of the population served by MTM, it is important to design the study to enhance the external validity/generalizability of the findings as much as possible. The investigators will recruit 200 participants from the referral list of Community Servings, a Boston-based MTM provider, and randomly assign them to MTM (N=100) or usual care + monthly food subsidy (N=100). MTM intervention will consist of 6 months of weekly delivery of 10 ready-to-eat meals (approximately half an individual's weekly food intake), along with telephone-based lifestyle intervention that prepares participants for the post-treatment period. The usual care + food subsidy recipients will receive usual care along with 6 months of a $40/month food subsidy.
연구 개요
상세 설명
Food insecurity, "lack of access to enough food for an active, healthy life", affects over 20% of the 30 million Americans with diabetes. Food insecurity is more common in racial/ethnic minorities and those with lower socioeconomic status. Moreover, food insecurity is associated with worse diabetes control and increased complications, even after adjusting for other risk factors. Food insecurity is a major contributor to disparities in diabetes outcomes.
Medically tailored meal (MTM) delivery programs are a promising intervention for individuals with diabetes and food insecurity. MTM programs deliver fully prepared food, tailored by a registered dietitian nutritionist to the specific medical needs of the individual, and provide education to help optimize disease self-management. Food insecurity is typically addressed with food subsidies-offering additional financial resources that can be spent on food. While both food subsidies and MTM can increase healthy food access, MTM can help overcome other barriers to diabetes management including lack of time, ability, knowledge, and skills needed to prepare appropriate meals. The use of these programs is often called 'food as medicine', as the purpose is to provide exactly the foods needed to help prevent diabetes complications. MTM are receiving increasing public attention, but there are, as of yet, no full-scale trials to test its effects on diabetes outcomes when compared with other food insecurity interventions.
Our research team has developed a medically tailored meal intervention that combines provision of healthy food, tailored to the specific nutrition needs of the individual, with an evidence-based lifestyle intervention that uses the period of meal delivery as springboard to improve diabetes self-management, both while receiving meals and after meal delivery is completed.
This study is an explanatory-focused randomized trial to assess a community-based medically tailored meals intervention (n=200). It will be conducted among diverse participants referred for medically tailored meals. Adults with type 2 diabetes, Hemoglobin A1c between 7.0% and 12.0%, and BMI ≥ 25 kg/m2 (≥ 23 kg/m2 for those with Asian ancestry) will be enrolled and randomly assigned to intervention or usual care + food subsidy. The intervention group will receive meal delivery and its attendant lifestyle intervention for 6 months, while the usual care + food subsidy group will receive a $40/month food subsidy, along with usual diabetes care.

실험적: Medically Tailored Meal (MTM)
The Medically Tailored Meal (MTM) intervention consists of weekly home meal delivery; an explanation of the medical tailoring of the meals; and a 6-session telephone lifestyle intervention change program designed to complement the period of meal delivery and prepare for the period after meal delivery with behavioral and skill-building approaches to sustain the benefit of the intervention. |

활성 비교기: Food Subsidy
As a comparison group, those not randomized to receive the MTM intervention will receive usual care provided by their clinicians not associated with the study, plus a food subsidy ($40/month) for 6 months, along with healthy eating information to guide use of that subsidy. |

Health-Related Quality of Life Score as Assessed by PROMIS (Patient-Reported Outcomes Measurement Information System)-29 at Month 6
기간: 6 months
|
The PROMIS-29 includes seven health related quality of life domains (Physical Functioning, Anxiety, Depression, Fatigue, Sleep Disturbance, Social Functioning, and Pain), and the pain domain has two subdomains (interference and intensity). Raw scores, except pain intensity, are transformed using the T-score metric based on the item response theory calibrations in which scores have a mean of 50 and standard deviation of 10 for the general population in the US. A higher PROMIS T-score implies more of the concept being measured; i.e., a higher PROMIS score on physical function indicates better functioning, whereas a higher score on depression indicates more severe depressive symptoms. These scores are then used to calculate a PROMIS-Preference (PROPr score) (PROPr scores range from -0.022 (worst) to 1.0 (best)). |
