Introduction:

overweight and obesity achieve a high prevalence among children and adolescents in Spain. Modifiable habits, combined with the genetic load and weight perception, declines over the years making children overweight adults. Our aim was to analyze the relevance in excess weight of various modifiable factors (dietary habits, physical activity, sedentary lifestyle and sleep), heredity and body image perception in children and adolescents.

Methods:

a retrospective observational study of 101 schoolchildren in Madrid (mean age 10 years) was performed with collection of anthropometric (weight, height, skinfold thickness and waist circumference), dietary (KidMed), physical activity (IPAQ adapted), sedentary lifestyle, sleep and perception of weight and body image data.

Results:

31% of children had excess weight. 53.4% ​​needed diet improvement. The number of participants with normal weight who did not follow a high adherence to the Mediterranean diet was greater than those with overweight-obesity who did adhered. No statistically significant results between weight status (according to weight percentile) and body parental characteristics were obtained, but according to BMI. 70% of obese and 50% of malnourished would like to stay in their weigh.

Conclusion:

modifiable factors were not associated with an increased excess weight. Parents' weight had some influence on the weight status of children, although no statistically significant results were obtained when both modifiable factors and heredity were analyzed altogether.
