Although the overall prevalence of overweight and obesity in children and adolescents has fallen slightly over the past decade, the rates of both conditions have increased in the most disadvantaged neighbourhoods. This is the conclusion of a new study based on data from more than one million children in Catalonia, which was carried out by the Barcelona Institute for Global Health (ISGlobal) and the IDIAPJGol Institute.
Levels of childhood overweight and obesity have plateaued in many middle- and high-income countries over the past decade, but prevalence rates remain high. In Spain, around 41% of children aged 6 to 9 years were overweight and/or obese in 2015—the second-highest prevalence rate in Europe. In the Catalonia region, childhood overweight and obesity rates are similar to those of Spain as a whole.
The new study, published in Jama Network Open, was based on data from 1.1 million children and adolescents in Catalonia aged 2 to 17 years with at least one height and weight record in the Information System for Research in Primary Care (SIDIAP) between 2006 and 2016. The children were divided into three age groups: 2-5 years, 6-11 years and 12-17 years. Prevalence rates and time trends for overweight and obesity were calculated and stratified by socio-demographic characteristics: age, sex, urban/rural residence, nationality, and the socioeconomic deprivation score of the family’s census tract, as calculated using the MEDEA index.
