Research also showed that Brazilian boys and girls are more obese

A recent study published in The Lancet Regional Health – Americas revealed that Brazilian children are growing more and showing higher rates of overweight and obesity. The research, conducted by experts from Cidacs/Fiocruz Bahia in partnership with UFMG and University College London, observed an average increase of 1 cm in children’s height and an increase in the prevalence of overweight and obesity.

The analysis was based on longitudinal data from more than five million children, aged 3 to 10, collected between 2001 and 2014. The results point to a global challenge in meeting the WHO target of reducing the prevalence of obesity by 2030.

The researchers used information from three Brazilian administrative systems, dividing children into two cohorts: born from 2001 to 2007 and from 2008 to 2014. An increase in height and BMI was observed, especially in the most recent cohort, with differences between boys and girls.

Despite the positive aspects associated with greater height, such as a lower risk of heart disease and greater longevity, the increase in overweight and obesity rates is a cause for concern. Changes in diet, such as the consumption of ultra-processed foods, and an increase in sedentary lifestyle are contributing factors.

The study highlights the need for prevention policies focused mainly on the poorest children, where obesity has increased significantly. These measures are essential to combat the risk of chronic non-communicable diseases associated with obesity.
