“…However, despite benefiting older adults, none of these programs were designed considering their specific needs. As mentioned by Lima-Costa et al (2022), Brazil has undergone a period of important cuts in social security and health program investments in the past 4 years, including the extinction of the National Council for Food and Nutrition Security (in Portuguese, Conselho Nacional de Segurança Alimentar e Nutricional -CONSEA), an important institution that fought against food insecurity in Brazil. The extinction of the council reduced the articulation of society within the federal, state, and municipal government spheres, diminishing actions and programs that help food insecure individuals and may have a greatly negative impact in the short-term (Ribeiro-Silva, Pereira, Campello, et al, 2020).…”

Food insecurity is a growing problem in Brazil, especially among older adults; however, the related sociodemographic factors remain unclear. This study aimed to analyze the relationship between social support dimensions and food insecurity among community-dwelling older adult Brazilians in São Paulo. This cross-sectional study was conducted in three cities in Sao Paulo state, Brazil. The analysis included 598 community-dwelling individuals aged ≥60-years-old, and multiple logistic regression models were used to estimate the associations between the dimensions of social support and food insecurity after adjusting for sociodemographic characteristics. We found that 42.3% of participants were food insecure. In the bivariate analysis, the higher scores in the affective, material, positive social interaction, and informational social support dimensions were statistically associated with the lower odds of food insecurity. In the multiple regression analysis, older adults who had a higher score of positive social interaction were less likely to have food insecurity, whereas the African American ethnicity and those older adults with a total family income ≤2 times of the minimum wage were more likely to have food insecurity. The results indicate that the positive social interaction emerges as an important factor associated with food insecurity among older adults, beyond that of other well-known social factors associated with food insecurity, highlighting the importance of screening for food insecurity and social support in primary care to avoid potential adverse health outcomes among older adults.

“…To ensure that the sample represents the urban and rural areas of the small, medium, and large municipalities, the ELSI‐Brazil sampling adopts a design with selection stages, combining stratification of primary sampling units (municipalities), census tracts, and households. 16 Design data from the 2010 National Brazilian Census carried out by the Brazilian Institute of Geography and Statistics (IBGE) was used as a basis to conduct the ELSI‐Brazil as a representative cohort. The estimated sample size was 10,000 individuals, from 70 municipalities across the country.…”

Introduction Subjective cognitive decline (SCD) may be an early symptom of Alzheimer's disease. We aimed to estimate the prevalence of SCD in Brazil and its association with dementia modifiable risk factors. Methods We used data of 8138 participants from the Brazilian Longitudinal Study of Aging (ELSI‐Brazil), a population‐based study that included clinical and demographic variables of individuals across the country. We calculated the prevalence of SCD and its association with dementia modifiable risk factors. Results We found that the prevalence of SCD in Brazil was 29.21% (28.22%–30.21%), varying according to region, sex, and age. SCD was strongly associated with hearing loss, low education, psychological distress, Brown/Pardo and Black races. Discussion The prevalence of SCD in Brazil is higher than in high‐income countries. Brown/Black races and dementia modifiable risk factors were associated with SCD. Public strategies that target SCD may help mitigate the incidence of dementia.

“…The Brazilian Longitudinal Study of Aging (ELSI-Brazil) is a nationally representative study of persons aged 50 years and older, conducted in 70 municipalities in the five regions of Brazil 28 . Pre-pandemic data for this analysis were obtained from the second wave of the ELSI-Brazil, conducted by faceto-face interview from August 2019 to March 2020, with 9,411 participants 29 . This pre-pandemic survey was considered the baseline for this study.…”

A decreased trajectory of loneliness among Brazilians aged 50 years and older during the COVID-19 pandemic: ELSI-Brazil

This study aimed to estimate prevalence of loneliness among older Brazilian adults over the first seven months of the COVID-19 pandemic and to identify the predictors of loneliness trajectories. Pre-pandemic data derived from face-to-face interviews of participants of the 2019-2020 Brazilian Longitudinal Study of Aging (ELSI-Brazil), which is a nationally representative study of community-dwelling individuals aged 50 years and over. Pandemic data were based on three rounds of telephone interviews among those participants, conducted from May to October 2020. Loneliness was measured by a single-item question, considering those who had at least two repeated measures. Explanatory variables included depression, living alone, leaving home in the last week, and virtual connectedness in the last month. Mixed-effects logistic regression was used to estimate odds ratios with their 95% confidence intervals (95%CI) and to investigate loneliness trajectories and their predictors. In total, 5,108 participants were included. The overall prevalence of loneliness in the pre-pandemic period was 33.1% (95%CI: 29.4-36.8), higher than the pandemic period (round 1: 23.6%, 95%CI: 20.6-26.9; round 2: 20.5%, 95%CI: 17.8-23.5; round 3: 20.6%, 95%CI: 17.1-24.6). A significant interaction (p ≤ 0.05) was evidenced only between depression and time; participants with depression showed a greater reduction in loneliness levels. Although loneliness levels in Brazil have decreased during the pandemic, this pattern is not present for all older adults. Individuals with depression had a more significant reduction, probably due to feeling closer to their social network members during the stay-at-home recommendations.
