Brief Summary

The investigators propose a church-based health promotion program designed to reduce colon cancer risk in a mostly African American community served by the Lincoln Memorial Church in South Los Angeles. The investigators propose involving 20 overweight/obese community members in a 10-session health promotion program featuring weekly cooking classes, didactic nutrition instruction and brief bouts of exercise. Behavioral aim is to increase participants' fiber intake from commonly consumed plant foods and reduce their intake of pro-inflammatory foods. They will be followed for 3 months from time of enrollment. Intervention is expected to increase participants' mean stool weight and improve their Bristol Stool Chart score. Intervention is expected to reduce waist circumference and systolic blood pressure of participants. These effects are expected to be accompanied by self-reports of increased fiber intake and reduced intake of saturated fat and refined sugar as well as evidence of increased physical activity.

Detailed Description

The investigators propose a church-based health promotion program designed to reduce colon cancer risk in a mostly African American community served by the Lincoln Memorial Church in South Los Angeles. The Los Angeles County of Public Health has divided the county into nine service planning areas (SPAs), of which South LA is one. Of all the SPAs, the South LA SPA has the highest prevalence of obesity and the lowest adherence to federal nutrition recommendations. With seed grant funds from a cooperative NIH grant shared by the Drew School of Medicine and University of California-Los Angeles (UCLA), the Lincoln Memorial Church of Los Angeles is sponsoring a behavioral intervention featuring 10 weekly sessions composed of cooking demonstrations, brief didactic nutrition education and 10-minute exercise bouts. All sessions will take place in the church kitchen and meeting room. Participants are expected to be 20 mostly African American, overweight/obese community members. The behavioral goal of the health promotion sessions is to encourage participants to eat more fiber-rich plant foods, minimally processed, to consume fewer pro-inflammatory foods including foods rich in saturated fat, sodium and refined sugar, and to engage in federally recommended amounts of physical activity. If research resources become available to enable blood chemistry results and/or fecal metagenomic results, the investigators would predict that 3 months after participant enrollment in the study, participants would experience a reduction in their high-sensitivity-C-reactive protein concentration and an increase in the relative abundance of obligate anaerobic bacteria relative to other bacteria in fecal samples. As seems likely, however, results will be limited to evaluating the weight and form of participant stool samples using the Bristol Stool Chart and evaluating participants' waist circumference and systolic blood pressure. The 3 month follow-up assessment is expected to show increased stool weight, improved Bristol Stool Chart score, decreased waist circumference, decreased systolic blood pressure, reduced intake of saturated fat and refined sugar, and increased weekly physical activity.

Study Design

• Allocation Method: NA
• Intervention Model: SINGLE_GROUP
• Primary Study Purpose: PREVENTION
• Blinding Strategy: NONE

Study Groups

Garden-fresh produce and exercise (GFPE)

Participants are encouraged to double their consumption of minimally processed fiber-rich plant foods, especially garden-fresh produce from the church community garden. Participants are also encouraged to limit pro-inflammatory foods rich in saturated fat, sodium and added sugar. Participants are also encouraged to engage in 150 minutes of moderate to vigorous physical activity per week, most likely in the form of brisk walking.

Group Type: EXPERIMENTAL

Garden-fresh produce and exercise

Intervention Type: BEHAVIORAL

The Garden-fresh produce and exercise (GFPE) health promotion intervention features 10 weekly sessions that take place after Sunday services in the Lincoln Memorial Church kitchen/meeting space. Each session includes a cooking demonstration focused on how to prepare and cook a meal composed of fiber-rich plant foods minimally processed. Each session also includes brief, didactic nutrition instruction and a 10-minute bout of physical activity.
