Body Quest Parent: A Text Message Parent Education Intervention to Supplement a School-Based Obesity Prevention Initiative for Third-Graders

School-based nutrition interventions can be a tool for encouraging parents to improve home food environments. However, interventions should address barriers to receiving and applying nutrition education such as time, money, transportation, preferences of family members, and limited cooking skills.1 Text-based education may address these barriers. Research shows that 91% of American adults are cell phone owners and 78% of lower-income cell phone owners send and receive texts.2

My Quest, an Intervention Using Text Messaging to Improve Dietary and Physical Activity Behaviors and Promote Weight Loss in Low-Income Women

Objective: To evaluate changes in dietary and physical activity behaviors and weight after implementation of a 12‐week text messaging initiative (My Quest). Design: The researchers conducted a 1‐group, pre‐ to posttest study design to determine changes after implementation of a text messaging initiative developed using the tenets of the Social Cognitive Theory. Setting: A total of 55 Alabama counties (84% rural) with high rates of poverty, overweight/obesity, and chronic diseases. Participants: Convenience sample of low‐income, primarily overweight/obese women (n = 104). Intervention: Short texts (n = 2–3/d) provided health tips, reminders, and goal‐setting prompts. Weekly electronic newsletters provided tips and recipes. Participant self‐monitored body weight weekly. Main Outcome Measure: Outcomes included goal setting, self‐efficacy, behavioral and environmental factors, self‐monitoring, and body weight; data collection occurred through text message response and online surveys. Analysis: Analyses were conducted using McNemar test (dichotomous data), Wilcoxon signed rank test (ordinal data), or paired t test (continuous data). Results: Participants significantly (P < .05) improved dietary and physical activity behaviors and food environment; increased dietary and physical activity goal setting; and reduced body weight. Conclusions and Implications: A low‐cost, text messaging initiative particularly targeting women residing in rural communities with high rates of poverty and obesity can promote weight loss and improve dietary and physical activity behaviors. Future studies may include a control group and social support component such as group text messaging.
