- Conditions
- ObesityDiabetes
- Interventions
- Behavioral: Weight loss intervention
- Registration Number
- NCT02863887
- Lead Sponsor
- Pennington Biomedical Research Center
- Brief Summary
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.
- Detailed Description
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.

Group Intervention Description Weight loss intervention 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. Delayed Treatment Control Group Weight loss intervention 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.
- Primary Outcome Measures
Name Time Method Percent weight loss Month 6 and Year 1 Percent weight loss will be calculated at 6 and 12 months.
- Secondary Outcome Measures
Name Time Method Satisfaction Questionnaire 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.
Change in Quality of Life 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.
Change in Blood Cholesterol Screening, Month 6 and Year 1 The Alere Cholestech LDX® Analyzer is engineered to provide accurate, actionable, and readily accessible cholesterol testing results. The Cholestech uses fingerstick sampling and small sample size (40μL) that makes results less time consuming and easy to obtain.
Change in Body Fat Percentage Screening, Month 6 and Year 1 The participant's body fat percentage is measured using the portable Tanita Body Composition Analyzer (SC-240).
Change in Blood Glucose 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.
Change in Blood Pressure 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.
Change in Food Intake 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.
Change in Physical activity 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.
Change in Pulse Screening, Month 6 and Year 1 Pulse will be measured using an automatic blood pressure cuff (Omeron, Model BP710 or similar). Participants will rest for approximately 5 minutes prior to pulse measurement to ensure accurate at rest reading.
