Detailní popis

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.

Zbraně a zásahy

Skupina účastníků / Arm
Intervence / Léčba
Experimentální: 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.
The intervention will involve utilizing trained community health coaches to deliver the weight loss intervention. There will be 10 group based sessions conducted at each church over 6 months. Session frequency will be 4 weekly sessions (4) for the first month, bimonthly sessions for 2 months (4) and monthly sessions for 2 months (2). The study is based upon weight loss strategies that have been utilized in the Diabetes Prevention Program. The group sessions will be augmented by utilizing text messages. The text messages will be delivered weekly and three types of messages will be delivered: 1) lesson content, 2) motivational, 3) behavioral prompts.
Experimentální: 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.

Sekundární výstupní opatření

Měření výsledku
Popis opatření
Časové okno
Change in Body Fat Percentage
Časové okno: Screening, Month 6 and Year 1
The participant's body fat percentage is measured using the portable Tanita Body Composition Analyzer (SC-240).
Screening, Month 6 and Year 1
Change in Blood Glucose
Časové okno: Screening, Month 6 and Year 1
The Alere Cholestech LDX® Analyzer is engineered to provide accurate, actionable, and readily accessible glucose testing results. The Cholestech uses fingerstick sampling and small sample size (40μL) that makes results less time consuming and easy to obtain.
Screening, Month 6 and Year 1
Change in Blood Pressure
Časové okno: Screening, Month 6 and Year 1
Blood pressure will be measured using an automatic blood pressure cuff (Omeron, Model BP710 or similar). Participants will rest for approximately 5 minutes prior to blood pressure measurement to ensure accurate at rest reading.
Screening, Month 6 and Year 1
Change in Food Intake
Časové okno: Screening, Month 6 and Year 1
The National Cancer Institute (NCI) fat screener estimates the percentage of energy from fat by asking patients to report the frequency of consuming specific foods over the past 12 months. A standard 7-item fruit and vegetable screener developed by the NCI and National 5 a Day Program grantees asks how often fruit and vegetables were consumed in the past month.
Screening, Month 6 and Year 1
Change in Physical activity
Časové okno: Screening, Month 6 and Year 1
The International Physical Activity Questionnaire (IPAQ) questionnaire is a self-report measure of physical activity. The metabolic equivalent task (MET) minutes in each domain of leisure time activity, that is, sedentary, light, moderate, and vigorous intensity, will be calculated. The IPAQ has been shown to be a reliable and valid measure of physical activity and has been sensitive to changes in physical activity resulting from intervention programs.
Screening, Month 6 and Year 1
Change in Quality of Life
Časové okno: Screening, Month 6 and Year 1
. Each participant's quality of life will be assessed using the Impact of Weight on Quality of Life Survey.
Screening, Month 6 and Year 1
Satisfaction Questionnaire
Časové okno: Month 6 and Year 1
Each participant's satisfaction with the different elements of the study, including the community health coaches, the intervention, and the text messages, will be measured using a questionnaire developed by the investigators.
