Insegurança alimentar e nutricional e os comportamentos de risco e proteção para saúde em adolescentes durante a pandemia de covid-19

Abstract

ABSTRACT The COVID-19 pandemic has reduced access to food and increased food insecurity. The objectives were to analyse the prevalence of Food and Nutritional Insecurity (FNI) in Brazilian adolescents during the COVID-19 pandemic according to sociodemographic characteristics and to examine the association between FNI and risk and protective behaviours in Brazilian adolescents during the that period. Cross-sectional study with data from the ‘ConVid teenagers – Behaviour Survey,’ carried out between June and October 2020, using a self-administered questionnaire via mobile phone or computer. The population was made up of teenagers aged 12 to 17, totalling 9,470. The Prevalence Ratio (PR) and 95% Confidence Interval (95% CI) were used, using Poisson regression with robust variance. The prevalence of FNI (26.1%) was higher among adolescents of black and mixed race/colour and who study in public schools. Adolescents who reported FNI had lower consumption of vegetables and fruits, less physical activity, and greater use of cigarettes and alcohol. FNI was more prevalent in adolescents with worse socioeconomic conditions, and adolescents with FNI showed a higher frequency of health risk behaviours, highlighting the importance of intersectoral public policies to reduce inequalities.
