RELATIONSHIP BETWEEN FOOD CONSUMPTION, BODY COMPOSITION AND SEDENTARY BEHAVIOR IN CHILDREN AND ADOLESCENTS WITH AUTISTIC SPECTRUM DISORDER
Autism Spectrum Disorder; Sedentary Behaviors; Food Intake; Screen time; Consumption of ultra-processed foods.
Introduction: It is important to emphasize that overweight is endemic in autistic children and adolescents, with inadequate nutrition and sedentary behavior being some of its etiological factors. Objective: To evaluate the relationship between dietary consumption, sedentary behavior, anthropometric profile, and body composition of children and adolescents with Autism Spectrum Disorder. Methodology: This is a quantitative cross-sectional and descriptive study. A total of 100 children and adolescents (8.53±2.95 years) of both sexes diagnosed with Autism Spectrum Disorder participated in the study, receiving care from the Specialized Care Center of Jaguaruana and the Specialized Educational Care. Questionnaires were used to assess the participants' socioeconomic profile, screen time, level of physical activity, and 24-hour dietary recalls. Body composition was assessed by measuring weight, height, waist, hip, and abdominal circumferences, as well as subscapular and tricipital skinfolds. Results: 75% of the participants demonstrated excess screen time. 74% of the children and adolescents (n=74) were classified as inactive. The majority presented obesity (40%, n=40) and overweight (27%, n=27) according to the Body Mass Index for Age. The body fat percentage showed a prevalence of low body fat distribution (37%), however, 36% of the participants had a moderately high to high percentage of body fat. Regarding dietary consumption, the main source of calories identified was from minimally processed or unprocessed foods, totaling 58.04%. However, ultra-processed foods contributed 35.25% of the caloric intake. Regarding the relationship between dietary consumption, sedentary behavior, screen time, and body composition, there were correlations between the variables. Conclusion: Statistically significant correlations were found between the consumption of ultra-processed foods, body composition, and sedentary behaviors in this population. As the intake of this food group increases, levels of body fat and anthropometric indicators of adiposity also increase. Additionally, the less time dedicated to physical activity, the higher the levels of body fat. At the same time, the more time spent on screen activities, the higher the percentage of body fat and indicators of excess body weight.
