Study Overview
Brief Summary
This is a cluster randomized trial (CRT) to assess the effectiveness of a culturally appropriate behavioral intervention to reduce obesity levels and ultimately the risk of developing diabetes type II in immigrant Latino farm workers. Randomization is at the farm ranch level. Individuals at intervention ranches will receive a multi-week curriculum at the work-site on diabetes, diet and physical activity and optional supplemental sessions in the evening and weekends. The investigators will adopt the intent-to-treat principle for the primary analysis. Individuals on control ranches will receive no health educational instruction. The primary outcome is BMI. The investigators hypothesize that intervention ranches will achieve significant improvement in obesity and diabetes risk factors as compared to control ranches.

Outcomes
Primary Outcomes
Change in BMI
Time Frame: Measured at baseline prior to the intervention; immediately following the intervention (12 weeks after first assessment) and again at 6 months, 1 year, and 1.5 years post-intervention.
Weight and height will be assessed at each data collection point and concurrently for control and intervention participants on matched ranches.
Secondary Outcomes
- Change in hemoglobin A1c (HbA1c)(Measured at baseline prior to the intervention; immediately following the intervention (12 weeks after first assessment) and again at 1 year post-intervention.)
- Cost analysis(Quarterly beginning a year prior to implementation of the intervention and concluding 1.5 years post-intervention.)
- Change in cholesterol(Measured at baseline prior to the intervention; immediately following the intervention (12 weeks after first assessment) and again at 1 year post-intervention.)
- Change in behavior and lifestyle factors(Measured at baseline prior to the intervention; immediately following the intervention (12 weeks after first assessment) and again at 1 year post-intervention.)
- Change in waist circumference(Measured at baseline prior to the intervention; immediately following the intervention (12 weeks after first assessment) and again at 6 months, 1 year, and 1.5 years post-intervention.)
- Change in blood pressure(Measured at baseline prior to the intervention; immediately following the intervention (12 weeks after first assessment) and again at 6 months, 1 year, and 1.5 years post-intervention.)
