Abstract

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.

巴西成年人的休闲屏幕时间和食物消费。

背景：屏幕时间，包括看电视（TV）、使用平板电脑、手机和电脑（电子设备）等活动，与不健康食品的消费有关。本研究旨在分析巴西成年人（≥18 岁）的长时间休闲屏幕时间与健康和不健康食品消费指标之间的关联：方法：采用2019年进行的全国健康调查（NHS）数据（n = 88,531）。从三个维度分析了长时间闲暇屏幕时间（屏幕时间≥3小时/天）：观看电视、使用电子设备和总屏幕时间（电视和电子设备）。食品消费从两个维度进行分析：健康食品（天然食品和微加工食品）和不健康食品（超加工食品）。使用泊松回归模型计算社会人口因素（性别、年龄、受教育程度、收入、居住地区和种族/肤色）和健康因素（体重状况、自评健康状况和是否患有非传染性疾病）的流行率（粗略比率和调整比率 (PRa)），以评估长时间使用屏幕与食物消费指标之间的关联：在巴西成年人中，长时间看电视的比例为 21.8%，长时间使用其他休闲电子设备的比例为 22.2%。女性、老年人以及收入和受教育程度较低的人群中，长时间看电视的频率最高。长时间使用电子设备在年轻人和中等教育及收入人群中更为常见。长时间使用屏幕与不健康的饮食习惯有关，因为不健康食品的消费量较高（电视的PRa = 1.35，电子设备的PRa = 1.21，两种类型的PRa = 1.32），而健康食品的消费量较低（电视的PRa = 0.88，电子设备的PRa = 0.86，两种类型的PRa = 0.86）：结论：在巴西成年人中，长时间使用屏幕与健康食品的消费呈负相关，而与不健康食品的消费呈正相关。

期刊介绍： International Journal of Environmental Research and Public Health (IJERPH) (ISSN 1660-4601) is a peer-reviewed scientific journal that publishes original articles, critical reviews, research notes, and short communications in the interdisciplinary area of environmental health sciences and public health. It links several scientific disciplines including biology, biochemistry, biotechnology, cellular and molecular biology, chemistry, computer science, ecology, engineering, epidemiology, genetics, immunology, microbiology, oncology, pathology, pharmacology, and toxicology, in an integrated fashion, to address critical issues related to environmental quality and public health. Therefore, IJERPH focuses on the publication of scientific and technical information on the impacts of natural phenomena and anthropogenic factors on the quality of our environment, the interrelationships between environmental health and the quality of life, as well as the socio-cultural, political, economic, and legal considerations related to environmental stewardship and public health.
