Healthier Troops in a SNAP (Scouting Nutrition & Activity Program) is a health promotion and obesity prevention program administered through Junior Girl Scout troops (for girls in grades 4-5) registered with the Girl Scouts of the USA. The intervention has three main components: (1) an interactive educational curriculum delivered by troop leaders; (2) troop meeting policies implemented by troop leaders; and (3) badge assignments completed at home by Girl Scouts with parental assistance. The focus of all three components is on physical activity, healthful eating, family meals, limiting television viewing, and choosing water over sugar-sweetened beverages. The educational curriculum consists of seven modules, delivered over the course of about 4 months. Each module includes discussion points for talking with girls about intervention target behaviors; a worksheet for goal setting and self-monitoring; a description of a recreational physical activity to be completed during the troop meeting (e.g., walking, dancing, yoga, active games); a fruit or vegetable snack recipe; suggestions for family meal role-playing (e.g., planning meals, practicing asking skills and good manners, clean-up); and a take-home assignment. The modules require 30-90 minutes to deliver, with flexibility allowed for specified program activities and module order. Badge assignments are completed at home by Girl Scouts with parental assistance.
Healthier Troops in a SNAP was created for and evaluated with Junior Girl Scout Troops. A modified version of the curriculum also has been developed for use with Brownies (i.e., for girls in grades 2-3). The study reviewed for this summary evaluated the original eight-module version of the curriculum. In response to feedback from troop leaders participating in the study, the curriculum has been consolidated into a seven-module format to take up less of the Girl Scout troops' yearly meeting programming.

Seven Girl Scout troops were stratified by size into large (n=4) and small (n=3) troops and then randomized within strata to either the intervention condition (received the SNAP program), in which there were 3 troops, 34 girls in total or the standard-care control condition in which there were 4 troops, 42 girls in total.. Girls ranged in age from 9 to 13 years (mean: 10.5 years); 77.6% of the sample was Non-Hispanic Caucasian, and 22.4% were racial/ethnic minority.
The primary outcome was child body mass index (BMI). Secondary outcomes included accelerometer-assessed physical activity levels during troop meetings and self-reported health behaviors, including fruit and vegetable consumption, habitual physical activity, sugar-sweetened beverage consumption, frequency of eating while watching television, and frequency of family meals.
To assess physical activity levels in troop meetings, a trained research assistant observed each troop during seven troop meetings over a period of about 7 months. The research assistant placed an accelerometer on each girl's right hip, using an adjustable elastic belt. The assistant recorded the starting time and the identification number of the accelerometer worn by each girl. Scouts wore the accelerometer for the duration of their meeting attendance. Using a 30-second epoch, raw accelerometer counts were processed through a customized software program for determination of time spent in moderate-to-vigorous, vigorous, moderate, light, and sedentary physical activity levels.
- During troop meetings, girls in intervention troops spent a significantly smaller percentage of Girl Scout meeting time engaged in sedentary activity (p=.011) and a significantly greater percentage of time engaged in moderate (p=.004) and moderate-to-vigorous physical activity (p<.001) compared with girls in control troops. No significant group differences were found for light or vigorous physical activity.
- No significant differences in BMI and self-reported health behaviors were observed between intervention and control groups.
