简要总结
The goal of The LEAN project intervention is to promote weight loss, healthy dietary habits, increased physical activity, improved blood glucose and cholesterol, and weight related quality of life in obese African American adults through a sustainable, technology enhanced, church-based program.
详细描述
The LEAN Project is a community-based weight loss program that is delivered through churches serving lower-income, obese, African American adults. The intervention will involve training community health coaches to deliver the intervention. These community health coaches will be individuals who are members of the church and who are willing to be trained on how to deliver behaviorally-based, empirically proven, lifestyle change interventions. These community health coaches will be trained by the staff at Pennington Biomedical, who have experience training and delivering these types of interventions. The community health coaches will deliver the intervention through their respective church after being trained. Weekly text messages will be sent to participants in order to supplement the intervention sessions and provide support. The primary aim is to determine if the trained community health coach church-based intervention will result in significant weight loss. Secondary aims will assess blood glucose, cholesterol, physical activity, food intake, and weight related quality of life.

研究组 & 干预措施
Weight loss intervention
Churches randomized to the intervention condition will receive the community health coach delivered church based intervention for 6 months followed by 6 months of weight maintenance.
干预措施: Weight loss intervention (Behavioral)
Delayed Treatment Control Group
Churches in the delayed treatment control condition will receive information on various health topics relevant to African Americans, such as strokes, lupus, sickle cell, etc. via text message during the first six months. Participants in this group will not receive any behavioral strategies designed to alter weight, physical activity, or diet during this time. They will receive the community health coach delivered church based weight loss intervention after 6 months.
干预措施: Weight loss intervention (Behavioral)
