Qualitative study explores Mexican mothers' perspectives on peer-led childhood obesity prevention

This qualitative study, embedded within a cluster randomized trial, explored the perspectives of 25 Mexican and Mexican American mothers whose children attended childcare centres implementing the Healthy Change program—a brief, peer-led intervention for early childhood obesity prevention. The study did not include a comparator group and focused exclusively on mothers from intervention sites. No quantitative outcomes, effect sizes, or comparative data were reported.

Mothers expressed generally favourable impressions of the program, citing practical advice, relatable peer facilitators, and a supportive group atmosphere as positive elements. They reported making intentional changes to family diet, routines, and physical activity opportunities. However, learning their child's weight status initially caused shock or discomfort, though this was often followed by greater recognition of obesity risk. Mothers identified program needs including broader content, clearer communication, and some professional involvement to complement peer support. Family encouragement facilitated change, while competing schedules and communication gaps served as barriers to participation.

No safety, tolerability, or adverse event data were reported. Key limitations include the small sample size (n=25), lack of a control group, and absence of quantitative measures of program effectiveness or child health outcomes. Findings are based solely on self-reported perceptions from a specific cultural subgroup within the intervention arm. The study suggests peer-led programs in childcare settings may be feasible and acceptable for supporting healthier family lifestyles, but these qualitative insights require validation through rigorous quantitative research measuring actual obesity prevention outcomes.
