Latino Youth Agricultural Study

Reducing Pesticide Exposure Among Latino Adolescents Through a Promotora-based Intervention

This project implements and evaluates a promotora-based intervention targeted at adolescent farm workers. The goal of the project is to determine the effectiveness of each intervention in promoting increased knowledge and practice of pesticide safety behaviors.

Study Overview

• Status: Completed
• Conditions: Pesticide Safety
• Intervention / Treatment: Behavioral: Safety Education Program

Detailed Description

This project implements and evaluates a promotora-based intervention targeted at adolescent farm workers. The intervention will be delivered to two different treatment groups: 1) adolescent only, adolescents receive the adapted adolescent version of La Familia Sana program and 2) family enhanced, adolescent and mother both receive the La Familia Sana program. In addition, there will be a control group where adolescent farmworkers will not be exposed to any pesticide safety program. Our project will:

1. Determine if a promotora-based intervention targeting pesticide safety in the workplace is effective in increasing knowledge about safety behaviors among Latino adolescents engaged in farm work.
2. Delineate variation by group among adolescents' knowledge about safety behaviors.
3. Delineate variation in adolescents' pesticide safety behaviors and neurological outcomes after intervention between all groups.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Youth-only; Only the youth receives the education program	Behavioral: Safety Education Program; this is a pesticide safety education program

No Intervention: Control; neither parent, nor youth receives the education program

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
knowledge of pesticide safety behaviors	This outcome measure will be assessed by a series of nine questions asking adolescents "How do you believe that farmworkers can come in contact with pesticides while working?" Additionally, nine additional questions will be asked that assess "How do you believe that farmworkers can have contact with pesticides while at home?" All responses for these questions are "yes" or "no"	7 weeks
Self-protective behaviors	Self-protective behaviors will be assessed by items asking adolescents about their clothes wearing and handling and their hand washing behaviors. Items regarding clothes wearing and handling include self-reported frequency of removing shoes and clothes prior to entering their home and wearing the same clothes more than one day. Additionally, several questions ask about the frequency of wearing shorts, sandals, gloves, etc. Regarding hand washing behavior, adolescents will self-report their hand washing behaviors at pretest and posttest. These questions ask youth about the frequency in which they wash their hands prior to eating, drinking, chewing gum, using the restroom, touching co-workers, etc. All self-protective behavior questions have a response option of "never", "sometimes", "usually", and "always"	7 weeks

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Neurological functioning	Neurological functioning in the form of coordination and fine motor skills will be assessed by the finger tapper test. This measure focuses specifically on speed and is sensitive to the effects of neurotoxicants. The finger tapper test produces a mean score for both the participant's dominant and non-dominant hand as a result of a series of 10 second tapping exercises.	7 weeks
