Sponsor's own description
Ecolectivos is a type-1 hybrid-effectiveness-implementation study that uses a village-level cluster randomized controlled trial design. The goal of this study in rural Guatemala is to assess intervention strategies to reduce plastic burning in 8 intervention villages compared to 8 control villages. The intervention group participants will participate in 12 weekly behavioral working group sessions; the control group will not receive any specific activities. Two hundred women of reproductive age and other community members from these villages will be enrolled in each group. The follow-up period is 12 months. Data will be collected via interviews, focus groups, air pollution sampling, plastic waste collection, urinary biomarker assessments, and ambient air sampling. Program evaluation and results dissemination will occur in the last year of the project.
