Background:

the prevalence of overweight and obesity in childhood and adolescence in Spain is alarming. The high consumption of processed products of low nutritional quality but high caloric density, together with sedentary lifestyle, are two of the main causes.

Objective:

to know the nutritional status of a population of children and adolescents, and some of their eating habits, tastes and preferences, and physical activity practice.

Methods:

a cross-sectional descriptive study based on an anthropometric assessment and a survey on food habits and lifestyle in 1,939 schoolchildren between seven and 16 years of school age in the Community of Madrid. Updated indexes such as the body mass index (BMI) adapted according to the Cole cut-off points and the waist-height index (CTI), which have a high correlation with infant adiposity, are used.

Results:

the rates of overweight and obesity are high in both children and adolescents. It should be noted that abdominal obesity according to ICT represents a greater percentage than global obesity diagnosed with BMI (overweight + total obesity according to BMI: 27.23%, and according to ICT: 35.17%). The sedentariness is high (25.12%), as well as the consumption of highly caloric products, but of low nutritional value mainly at breakfast, mid-morning and snack.

Conclusions:

the prevalence of overweight and obesity is high, especially at the abdominal level, probably associated with the increasing consumption of ultra-processed products and the high rates of sedentary lifestyle. The conclusion is the need to develop programs to prevent obesity and nutritional education.
