Diabetes Prevention Program for Obese Latino Youth (ELSC)
Community-Based Diabetes Prevention Program for Obese Latino Youth: Every Little Step Counts
調査の概要
詳細な説明
Obesity in the United States has reached epidemic proportions and Latinos youth are disproportionally impacted. Pediatric obesity is associated with several chronic health conditions including insulin resistance and type 2 diabetes. However, very few interventions specifically targeting diabetes prevention for obese Latino adolescents have been developed.
Therefore, the purpose of this study is to examine the effects a culturally-grounded, community-based lifestyle intervention on psychosocial and health outcomes among obese Latino adolescents. Eligible participants of this study will be randomly selected to the intervention group or the delayed-intervention group (control group) after an initial health screening for eligibility.
Participants selected to the intervention group will attend weekly healthy lifestyle education sessions with their parent(s)/guardian(s) and three physical activity sessions / week with other youth. After which, participants will attend monthly booster group meetings for three months.
All participants will be assessed at baseline, 3 months, 6 months, and 12 months for insulin sensitivity, glucose tolerance, quality of life, fitness, and nutrition and physical activity behaviors.

実験的:Every Little Step Counts Intervention
Exercise classes (3/week) Lifestyle sessions (1/week)
|
Youth participants randomized to participate in the experimental group will attend weekly healthy lifestyles education session with their parent(s)/guardian(s) and will also attend exercise sessions 3 times a week for 12 weeks.
The education sessions will cover topics such as healthy eating choices, roles and responsibilities of both parents and youth in the realm of the family unit as well as in youth's own health, and self esteem among other topics.
The exercise sessions will incorporate both aerobic and resistance training as well as other "free-play" physical activities i.e. basketball, volleyball etc.

These secondary outcomes measures aim to explore the mechanisms of the intervention by assessing the "mediated effect" on the outcomes of insulin sensitivity and weight-specific QoL through the following putative mediators targeted in the program: self-efficacy for healthy eating and exercise.
