Garden-fresh Produce and Exercise Reduce Colon Cancer Risk (GFPE)

Study Description
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.

Arms and Interventions
Arm Intervention/treatment
Experimental: 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.
 Behavioral: Garden-fresh produce and exercise
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.

Outcome Measures
Primary Outcome Measures :
  1. Stool weight [ Time Frame: At baseline and 3 months post-enrollment ]
    Mean stool weight of single bowel evacuation using precision digital scale


Secondary Outcome Measures :
  1. Bristol Stool Chart score [ Time Frame: At baseline and 3 months post-enrollment ]
    Bristol Stool Chart score ranges from 1 (hard lumps) to 7 (soft, diarrhea, liquid)

  2. Waist circumference [ Time Frame: At baseline and 3 months post-enrollment ]
    Waist circumference measured over light clothing using tensioner-equipped waist circumference measuring device

  3. Systolic blood pressure [ Time Frame: At baseline and 3 months post-enrollment ]
    Resting blood pressure assessed in participant seated quietly at a table with legs uncrossed

  4. Ratio of fruit and vegetable fiber intake to total solid food intake [ Time Frame: At baseline and 3 months post-enrollment ]
    The ratio of fruit and vegetable fiber intake relative to total gram weight of foods consumed per day based on data from Block Food Frequency questionnaire.

  5. Saturated fat intake [ Time Frame: At baseline and 3 months post-enrollment ]
    Mean grams (g) of saturated fat intake consumed daily based on retrospective food consumption data obtained from administration of the Block Food Frequency questionnaire. The Daily Value for saturated fat is less than 20 g per day, based on a 2,000 calorie diet. Meat-eating Americans generally consume more than 20 g per day but usually don't exceed 80 g per day. Humans make all the saturated fat that they need, so consuming zero g of saturated fat per day is consistent with good health.

  6. Sugary beverage intake [ Time Frame: At baseline and 3 months post-enrollment ]
    Percent of daily calorie intake attributable to sugary beverage intake
