This is the first of two documents prepared by experts for the Brazilian S20 mental health report. These reports outline strategies aimed at addressing the exacerbated mental health challenges arising from a post-pandemic world. Ongoing psychiatric epidemiology research has yielded evidence linking mental health with intricate social determinants, including gender, race/ethnicity, racism, socioeconomic status, social deprivation, and employment. More recently, the focus has expanded to also encompass violence and social oppression. By prioritizing prevention and early intervention, harnessing technology, and fostering community support, we can mitigate the long-term impact of emerging mental disorders throughout the life course. By utilizing evidence-based practices and forging partnerships between the health and education sectors, S20 countries can promote the health and safety of their student population, paving the way for a more promising future for the next generations. The first document focuses on addressing the mental health concerns of vulnerable populations, catering to the needs of children, youth, and aging populations, assessing the current state of alcohol and drug addictions, scaling up psychosocial interventions in primary care, exploring the potential integration of health and educational systems, and emphasizing the imperative adoption of human rights in mental health policies.

Objectives: Rural residents are exposed to many risk factors for poor diet quality, such as low socioeconomic status and food insecurity. However, the differences between urban and rural residents regarding the association of fruit and vegetable consumption with cognitive performance have not been explored. The aim of this study was to investigate the association of fruit and vegetable consumption with cognitive performance in urban and rural areas in a nationally representative sample of Brazilian older adults. Methods: The sample included 9,412 adults aged 50 years or older from the Brazilian Longitudinal Study of Aging (Estudo Longitudinal da Saúde dos Idosos Brasileiros [ELSI]). The association between consumption of fruits and vegetables and cognitive performance was evaluated using linear regression. Results: In 8,158 participants (mean age 61.6 ± 9.3 years, 54% women, 44% White, and 15% from rural areas), the mean frequency of fruit and vegetable consumption was 2.0 ± 1.3 times a day. Higher intake of fruits and vegetables was associated with better memory (β = 0.031, 95%CI 0.014-0.049), verbal fluency (β = 0.030, 95%CI 0.004-0.056), and global cognition (β = 0.035, 95%CI 0.015-0.055) performance in urban, but not rural residents (p for interaction = 0.036). Conclusion: Higher frequency of fruit and vegetable intake was associated with better cognitive performance in urban, but not in rural areas in Brazil.
