Childhood overweight and obesity rates fall slightly overall
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) --a centre supported by "la Caixa"-- 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.
In general, the findings showed that the prevalence of overweight and obesity decreased slightly in both sexes and all age groups. During the ten-year study period, rates of overweight and obesity fell from 40% to 38% in girls aged 6 to 11 years and from 42% to 40% in boys of the same age group. However, prevalence rates rose in the most deprived urban areas and in children of non-Spanish nationalities.
In areas with lower socio-economic levels, rates of overweight and/or obesity increased slightly, whereas wealthier areas saw a significant decrease, leading to a wider inequality gap. For example, between 2006 and 2016, the obesity rate in girls aged 6 to 11 years fell by 15.8% in neighbourhoods with the highest socio-economic level but increased by 7.3% in the most disadvantaged areas. The study also found that children between 6 and 7 years of age were the most vulnerable to developing overweight and/or obesity.
