简要总结
The purpose of the Deaf Weight Wise 2.0 (DWW 2.0) study is to test an evidence-based, comprehensive program to modify obesity-related health behaviors with Deaf people ages 21 to 70 who use American Sign Language (ASL) as their primary language. Participants will be randomized to one of four arms: immediate intervention vs. intervention delayed one year, and in-person group intervention vs. individual intervention delivered via videophone. The investigators' primary hypothesis is that participants in the immediate DWW 2.0 intervention will increase their physical activity and reduce their caloric intake and body weight compared with those in the delayed intervention group (no intervention yet).

入选标准
- •Deaf men and women ages 21-70 years who use sign language and live in the Rochester Metropolitan Statistical Area (MSA),
- •have a body mass index (BMI) of 25-
- •Eligible subjects must also have permission to participate from a primary healthcare provider if: 1) self-reported diagnosis of a recent cardiovascular disease event (heart attack or stroke in past 6 months), 2) self-reported heart condition, chest pain, dizziness, or other reason not to participate in physical activity, 3) had weight loss surgery in the previous 2 years (self-reported), and 4) are pregnant (self-reported).
- •Subjects must also be willing to follow a healthy dietary pattern and to abstain from using weight loss medications during the study, and be willing and able to attend either group or videophone sessions, and to participate in data collection requirements.
排除标准
- •Exclusion criteria include: subjects without medical clearance who had 1) a cardiovascular disease event in the past six months, 2) or heart condition, chest pain, dizziness, or other reason not to participate in physical activity, 3) or weight loss surgery in the past two years, or 4) are pregnant. Participants with these conditions (as determined by the PAR-Q Physical Activity Readiness-Questionnaire and other questions administered during the initial study screening visit) must obtain medical clearance from their primary healthcare clinician (or maternity care clinician for pregnancy) to be eligible. Those who are unable or unwilling to provide written, informed consent, and inability to see and interact with computer-based questionnaires and educational interventions will be excluded.
结局指标
主要结局
Change in BMI (Body Mass Index)
时间窗: 6-month BMI - baseline BMI
measure mean change = 6-month BMI - baseline BMI, for the immediate and delayed intervention groups (change from pre to post intervention).
Change in Physical Activity
时间窗: 6-month MET-min/wk - baseline MET-min/wk
change in amount of physical activity = 6-month MET-minutes/week - baseline MET-minutes/week (change from pre to post intervention), using the International Physical Activity Questionnaire. IPAQ score is a continuous measure and reports median MET-minutes per week (a combination of walking met-minutes/week + moderate activity MET-minutes/week + vigorous activity MET-minutes/week).
Change in Body Weight (kg)
时间窗: 6 month weight (kg) - baseline weight (kg)
measure mean change = 6-month weight - baseline weight, for the immediate and delayed intervention groups (change from pre to post intervention).
