Prevalência e fatores associados aos comportamentos de risco para doenças crônicas não transmissíveis em adolescentes e adultos jovens do Brasil

Abstract

Title: Prevalence and factors associated with disease risk behaviors non-communicable diseases in adolescents and young adults in Brazil Introduction: Unhealthy lifestyle behaviors such as smoking, alcohol consumption, unhealthy diet, physical inactivity and excess weight are highly prevalent in adolescents and young adults, and can contribute to the development of NCDs and premature mortality in the adult. Objective: Estimate the magnitude and factors associated with risk behaviors for NCDs in adolescents and young adults in Brazil. Methods: Cross-sectional, baseline study population, which used as a data source the National Health Survey conducted in 2019. The population analyzed were teenagers and young people aged 15 to 24. The data were collected through individual interviews during home visits, through a standardized form. The dependent variables included the main risk factors for Chronic Noncommunicable Diseases (NCDs). The demographic variables and socioeconomic variables were used as independent. Multiple regression models Poisson were applied to investigate the magnitude of the association between the independent variables and the dependent variables. The PNS 2019 was approved by the National Ethics Commission in Research (opinion: 3,529,376). Results: 10,460 individuals (5,001 men and 5,459 women). Regardless of gender, the most common risk factors prevalent were the nonrecommended consumption of fruits and vegetables (92.6%) and physical inactivity during leisure time (43.3%). The prevalence of tobacco smokers, consumption of alcoholic drinks once or more a month and alcohol abuse were 8.9%, 28.7%, 18.5%, respectively. The prevalence of regular consumption of soft drinks and/or artificial juices was 17.2%. The prevalence of excess weight was 32.5%. Compared to women, men had a higher prevalence of smoking, consumption of alcoholic beverages once or more a month, abusive consumption of alcoholic beverages, insufficient consumption of fruits and vegetables and consumption of ultra-processed. On the other hand, women had a higher prevalence of physical inactivity during leisure time and being overweight. Young adults, males and individuals with less education, of black race/color, with lower family income and Residents of urban areas had a higher prevalence for most risk factors. risk. Conclusions: There was a high prevalence of risk factors in adolescents and young Brazilian adults, mainly among young men and women individuals with less education, of black race/color, with lower family income and residents of urban areas. These results indicate the need for policies to reduction in the magnitude of risk factors for NCDs in adolescents and young adults in Brazil. Relevance and impact: This is the first comprehensive study that estimated the prevalence and factors associated with risk behaviors in adolescents and adults young people, including the non-student population. The results of the study can support specific actions for this population within the Strategic Action Plan for the Coping with Chronic Diseases and Non-Communicable Diseases in Brazil 2021-2030 of the Ministry of Health, including intensification of health promotion actions and disease prevention in subpopulations with a higher prevalence of risk factors.
