Socioeconomic disparities in diet and physical activity in children: evidence from well-child visit electronic health records in the Canary Islands, Spain.

Background: Diet and physical activity (PA) in childhood are heavily influenced by the living environment. While diet quality follows a socioeconomic pattern, limited evidence is available in relation to PA in children. We assessed the effect of socioeconomic status at the individual (SES) and neighbourhood (NSES) levels on diet and PA among children from the general population of the Canary Islands, Spain.
