La Vida Buena Childhood Obesity Program

Study Overview
=================
Brief Summary
-----------------
Mariposa Community Health Center, a health center in Nogales, Arizona on the US-Mexico border, will provide a program to prevent obesity in children and create a community environment that supports a healthy lifestyle. Mariposa designed and implemented the La Vida Buena (The Good Life) program and already know that helps families eat more healthily and exercise. Mariposa Community Health Center will test this program on younger children aged 5-8 years old. Providers will refer children who are overweight or obese to the La Vida Buena Program. In order to determine if the La Vida Buena program works, Mariposa Community Health center will implement the 8-week program with 100 overweight or obese children in their Nogales clinic. They will measure their weight (BMI), exercise levels and food habits at the beginning of the program and then 3- months and 6-months after the program ends. Mariposa will compare these results to children in the nearby Rio Rico clinic who do not receive the La Vida Buena program. These 100 overweight or obese children in Rio Rico will instead receive one educational session, and the same information will be collected regarding BMI, exercise level and food habits. After the 6-month period, the children from Rio Rico will be able to receive the full La Vida Buena program.

Detailed Description
-----------------
La Vida Buena is a Mariposa project to educate children and families about healthy eating and exercise habits. The Health providers at Mariposa Nogales and Rio Rico clinics will refer children between 5-8 years old who are overweight or obese and their parents. Each child must participate with a parent or adult caregiver who is at least 18 years old. Before the program begins, the participant will attend an informational consent/registration session where they will be asked to sign a consent form for themselves and their child if they want to participate. The study will ask for certain information from each participant in order to determine if the program is working. Each family will respond to a questionnaire at three points: at the beginning of the program, three months after beginning the program, and six months after beginning the program, for a total of six months. The questionnaire will include questions about fruit, vegetable and carbohydrate consumption, family behavior and habits regarding eating and exercise, moderate and vigorous physical activity, sedentary behavior, local foods and environment factors that impact the family. In addition, the child's weight will be measured at each time point. Participation in La Vida Buena will take 6 months. At the Nogales site, participants will be invited to a series of weekly classes over the course of 8 weeks that are being offered by the Mariposa clinic related to child healthy weight, exercise and nutrition. At the Rio Rico site, participants will be offered one face to face educational session about child healthy weight with Mariposa staff. Participants will be scheduled for BMI measurements and questionnaires three months after initiating the program, as well as six months after initiating the La Vida Buena Program.
