Brief summary
This is a study 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. Workers enrolled in a 2:1 ratio by random allocation into an intervention or control arm of the study. The intervention participants received weekly classes for 10 weeks with education on diabetes, diet and physical activity and practical exercises. Both control and intervention were measured for weight, waist circumference, fasting blood glucose and interviewed before and after the study intervention. The main hypothesis was that intervention, but not control participants, would experience reduction in body measurements after the intervention.

Interventions
BEHAVIORALBehavioral Intervention
Intervention participants attended up to 10 educational sessions teaching them about diabetes, and modifiable lifestyle factors (behaviors) to reduce the risk of diabetes by controlling weight. Sessions were conducted by Promotoras using culturally sensitive and appropriate materials and themes. Group activities and support were also emphasized. The control participants like the intervention were measured and interviewed before and again after the intervention sessions, but received no educational instruction or materials.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in BMI | Before intervention and after (12-14 weeks after first assessment) | Weight and Height assessed for both control and intervention participants before intervention program and then assessed 2-3 weeks after the intervention period completed. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in Waist Circumference | Measured before and after intervention (12 - 13 weeks after first assessment | Waist circumference measured in both control and intervention participants using a standard protocol. Conducted before intervention started and again 2-3 weeks after the intervention sessions finished. |
Other
| Measure | Time frame | Description |
|---|---|---|
| Change in fasting blood glucose | Measured before intervention and after (12-13 weeks after first assessment) | Fasting blood glucose was a voluntary assessment and therefore not conducted in all participants. Blood glucose was assessed from a middle digit using a sterile lancet and Accu-Check Advantage Blood Glucose Meter. It was assessed before the start of the intervention and after completion in both controls and intervention participants. |
