<b>Confinamiento social por SARS-COVID 19: cómo afectó a los factores modificables del estilo de vida de la población infantil en Comodoro Rivadavia</b>

Obesity is the primary risk factor for chronic diseases. Due to SARS-COVID-19, strict confinement was ordered, implying a drastic change regarding the quality of life. This study aimed to assess the impact of social confinement on modifiable lifestyle factors in children in the city of Comodoro Rivadavia. A cross-sectional descriptive study was conducted on 390 volunteers aged 6 to 11 years. With a written, signed consent, anthropometric measurements (weight, height, and waist circumference) were taken, BMI Z-scores calculated, and blood pressure measured. A semi-structured validated survey was used to gather lifestyle habits. It was observed that 49.5% of participants had overweight or were obese, and 5% had elevated blood pressure. During confinement, 96.5% had breakfast, 93.5% included fruits and vegetables in their diet, 75.3% engaged in one hour of weekly moderate physical activity, and 79.0% spent more than two hours in front of screens. After isolation, 72.1% had daily breakfast, 93.7% ate fruits and vegetables, 76.6% engaged in weekly physical activity, and 72.3% spent over two hours in front of screens (p ≤ 0.05). In neither period did participants meet recommended fruit and vegetable consumption. Cereal intake was slightly higher during isolation (94.4% vs. 92.1%) (p ≤ 0.05). Social confinement significantly impacted modifiable lifestyle factors.
