Examining the association of sociodemographic characteristics on self-reported changes in health-related behaviors, mental health, and quality of life during the COVID-19 pandemic in Brazil.
Article in BMC public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe challenges faced during COVID-19 for the public health were unprecedent in the last 100 years. The necessity to adapt lifestyles during this period highlighted inequalities in health-related behaviors, quality of life and mental health of the population, especially in unequal countries like Brazil.
aimTo analyze the associations of sociodemographic characteristics and recalled changes in health-related behavior, mental health, and quality of life during the COVID-19 pandemic Brazil.
methodsQuantitative, web-based representative survey study of Brazilian adults (≥ 18 years). Sampling procedures proportionally considered state population and characteristics to complete quotas based on gender, age group, and socioeconomic status. Health-related outcomes included changes, from before the COVID-19 pandemic to during the COVID-19 pandemic, in habitual physical activity (no change, decrease and, increase), diet behaviors (no change, growth), quality of life (no change, decrease and, increase), and mental health tertile (4–6, 7–9 and 10–16). Variables used to characterize inequalities included gender (male/female), race (white, black, pardo and, other), and educational attainment (less than high school, high school and, higher education). Frequency distribution and multinomial regression were performed with SPSS 23.0 with a significance level 0.05.
resultsMost participants changed physical activity behaviors (77.5%), diet (56.5%), and perceived quality of life (37.9%). Women were less likely to decrease their physical activity, quality of life, and mental health. Among ethnic groups, blacks were less likely to increase unhealthy food consumption. Finally, groups with less than a high school education were more likely to have an unhealthy diet and lower odds of negative mental health scores.
conclusionBeing a woman, black, or having lower educational attainment was found to be associated with changes in health-related behaviors during the COVID-19 pandemic in Brazil, underscoring the contribution of COVID-19 to widening health inequities.
