Background: Screen time, involving activities like watching television (TV), and using tablets, mobile phones, and computers (electronic devices), is associated with the consumption of unhealthy foods. This study aimed to analyze the association between prolonged leisure screen time and healthy and unhealthy food consumption indicators among Brazilian adults (≥18 years). Methods: Data from the National Health Survey (NHS), conducted in 2019 (n = 88,531), were used. Prolonged leisure screen time (screen time ≥ 3 h/day) was analyzed in three dimensions: watching TV; use of electronic devices; and total screen time (TV and electronic devices). Food consumption was analyzed in two dimensions: healthy (in natura and minimally processed foods) and unhealthy (ultra-processed foods). Poisson regression models were used to calculate prevalence ratios (crude and adjusted (PRa)) by sociodemographic factors (sex, age, schooling, income, area of residence, and race/color) and health factors (weight status, self-rated health, and presence of noncommunicable disease), to assess the association between prolonged screen time and food consumption indicators. Results: Among Brazilian adults, the prevalence of prolonged screen time was 21.8% for TV and 22.2% for other electronic devices for leisure. The highest frequency of watching TV for a prolonged time was observed among women, older adults, and those with a lower income and schooling. Prolonged use of electronic devices was more common among young adults and those with intermediate schooling and income. Prolonged screen time was associated with an unhealthy diet, due both to the higher consumption of unhealthy foods (PRa = 1.35 for TV, PRa = 1.21 for electronic devices, and PRa = 1.32 for both types) and the lower consumption of healthy foods (PRa = 0.88 for TV, PRa = 0.86 for electronic devices, and PRa = 0.86 for both). Conclusions: Prolonged screen time was negatively associated with the consumption of healthy foods and favored the consumption of unhealthy foods among Brazilian adults.

Resumo Objetivo: Descrever e comparar os resultados dos principais fatores de risco e proteção para doenças crônicas não transmissíveis, nas 26 capitais brasileiras e no Distrito Federal, obtidos pela Pesquisa Nacional de Saúde (PNS) e pelo Sistema de Vigilância de Fatores de Risco e Proteção para Doenças Crônicas por Inquérito Telefônico (Vigitel) em 2019. Métodos: Estudo transversal, no qual se calculou a diferença na prevalência entre os indicadores de comportamentos de saúde investigados pela PNS e Vigitel. Resultados: As maiores discrepâncias entre os inquéritos, PNS (n = 32.111) e Vigitel (n = 52.443), foram observadas para prática de atividade física no lazer (6,8 pontos percentuais - p.p.), prática recomendada no deslocamento (7,4 p.p.) e tempo elevado de tela (21,8 p.p.). Foram semelhantes nos dois inquéritos as prevalências do estado nutricional, consumo alimentar, tabagismo, consumo abusivo de álcool e de autoavaliação negativa do estado de saúde. Conclusão: Os inquéritos apresentaram prevalências com pequenas diferenças, mas que apontam resultados na mesma direção.

Adequate fruit and vegetable consumption is recognized for its health benefits, including preventing noncommunicable diseases, therefore it should be monitored over the years. This study aimed to investigate the temporal trend of fruit and vegetable consumption among Brazilian adults (≥ 18 years) residing in 26 Brazilian capitals and the Federal District from 2008-2023. A time-series analysis of the Surveillance of Risk and Protective Factors for Chronic Diseases by Telephone Survey (Vigitel) was conducted. Regular (≥ 5 days/week) and recommended (≥ 5 servings/day on ≥ 5 days/week) fruit and vegetable consumption were analyzed for total population and sociodemographic groups. Prais-Winsten regression models were used to identify trends in the entire (2008-2023), initial (2008-2014) and most recent (2015-2023) periods. Regular and recommended consumption remained stable from 2008 to 2023. From 2008 to 2014, regular consumption increased in total population (0.71pp/year) and all sociodemographic groups, except for adults aged 25-34 years. From 2015 to 2023, regular consumption decreased in the total population (-0.56pp/year), mainly among men (-0.70pp/year), adults aged 25-34 years (-0.84pp/year), and with higher schooling (-0.96pp/year). The recommended consumption increased from 2008 to 2014 (0.81pp/year), mainly among women (0.90pp/year), adults aged 55-64 years (0.96pp/year), and those with higher schooling (0.77pp/year). The recommended consumption decreased from 2015 to 2023 in total population (-0.52pp/year) and all sociodemographic groups, except for men and adults aged ≥ 65 years. The Brazilian fruit and vegetable consumption increased from 2008 to 2014 but reduced recently (2015-2023).

We aimed to identify the temporal trend of multimorbidity of noncommunicable disease (NCDs) among Brazilian adults (n = 784,479) over a 16-year period of time. This is a time series of cross-sectional studies based on data from the Surveillance System of Risk and Protective Factors for Chronic Diseases by Telephone Survey (Vigitel) from 2006 to 2021. The presence of multimorbidity was assessed from the co-occurrence of (1) obesity and diabetes; (2) obesity and hypertension; and (3) obesity and diabetes and/or hypertension. Linear regression models (Prais–Winsten) were used to identify significant trends for the complete period (2006–2021) and the most recent quinquennium (2017–2021). Multimorbidity of obesity and diabetes and/or hypertension increased in the complete period (5.5% to 9.6%; 0.22 pp/year) and the most recent period (8.3% to 9.6%; 0.40 pp/year) studied. The highest increase occurred especially among men, older adults, and those with fewer years of education. Additionally, there was a high prevalence and an intense increase in multimorbidity among adults with poor self-rated health. These results reinforce the need for expanding and strengthening public health actions focused on individuals with multimorbidity especially with obesity.

Our objective was to analyze temporal trends in the prevalence of self-reported hypertension among Brazilian adults and to investigate differences in health behaviors between individuals with and without hypertension between 2006 and 2019. Data from the Surveillance System for Risk Factors and Protection for Chronic Diseases by Telephone Survey were analyzed (n = 730,309). Prais–Winsten regression was used to identify linear trends in the prevalence of hypertension for the entire period (2006–2019) and for the past 5 years. Poisson regression models were used to investigate the differences in health behaviors among individuals with and without hypertension. The prevalence of hypertension (approximately 24.0%) remained stable from 2006 to 2019 and decreased from 25.1% to 24.6% from 2015 to 2019. In the adjusted analyses, individuals with hypertension showed a significant association with unhealthy lifestyle habits: lower recommended intake of fruits and vegetables (APR = 0.97; p = 0.022), lower regular intake of fruits (APR = 0.98; p < 0.001), lower regular intake of beans (APR = 0.97; p < 0.001), lower leisure-time exercising (APR = 0.89; p < 0.001), higher abusive consumption of alcoholic beverages (APR = 1.04; p = 0.004), higher prevalence of overweight (APR = 1.40; p < 0.001), and higher prevalence of obesity (APR = 2.17; p < 0.001). Hypertension prevalence has remained stable during the entire period and decreased in the most recent period. Individuals with hypertension reported unfavorable scenarios for healthy habits.
