Childhood obesity in Mexico: A critical analysis of the environmental factors, behaviours and discourses contributing to the epidemic.

Mexico has the highest prevalence globally for children who are overweight. We conducted a qualitative study to understand childhood obesity in Mexico and the complex factors at play. Data were collected at three elementary schools in a low socio-economic area in Mexico City. Semi-structured interviews were conducted with 60 children, 24 parents and 28 teachers. The children interviewed were between the ages of 8 and 12 years old. Interview texts were analysed using NVivo 9 and 10 and thematic discourse analysis was used. Findings revealed how children's choices around nutrition and physical activity were constrained by their environment and discursive constructions.
