At the study level, weaknesses in the assessment of exposure and outcome may have introduced bias. Most studies investigated a cohort subgroup that may have resulted in selection bias. At the review level, there is a risk of publication bias and, in addition, narrative analyses are more prone to subjectivities than meta-analyses. Diet may potentially influence the risk of depression, although the evidence is not yet conclusive. Strengthening healthy-eating patterns at the public health level may have a potential benefit. Robust prospective cohort studies specially designed to study the association between diet and depression risk are needed.

Resumo Objetivo Analisar a associação entre as desigualdades sociais e sanitárias, condições socioeconômicas, segregação espacial e letalidade por COVID-19 em Fortaleza, Ceará, Brasil. Métodos Estudo ecológico de casos confirmados e óbitos por COVID-19, tendo como unidades de análise os 119 bairros de Fortaleza. Calcularam-se os indicadores de incidência, mortalidade e letalidade aparente por COVID-19, entre 1º de janeiro e 8 de junho de 2020. Indicadores socioeconômicos foram extraídos do Censo Demográfico do Brasil de 2010. Foi realizada análise espacial e calculados índice global e local de Moran. Resultados Foram encontrados 22.830 casos confirmados, 2.333 óbitos e uma letalidade aparente de 12,7% (IC95% 11,6;13,9). Observaram--se autocorrelações espaciais significativas para letalidade aparente (I=0,35) e extrema pobreza (I=0,51), sobrepostas em diversos bairros da cidade. Conclusão A letalidade aparente por COVID-19 está associada a piores condições socioeconômicas e de saúde, demonstrando a relação entre desigualdades sociais e desfechos de saúde em tempos de pandemia.

This article aims to assess the sociodemographic and epidemiological factors associated with AIDS and tuberculosis-HIV coinfection mortality in the Chilean adult population between 2000 and 2017. This is a retrospective observational study, evaluating the incidence density of TB-HIV coinfection mortality in the population over 14 years of age. We used data from the Chilean AIDS Cohort database, 17,512 people enrolled in highly active antiretroviral therapy in the public health system in Chile. The Kaplan-Meier survival function and Cox regression were applied. Incidence density of 0.05 for 39,283 person-years for mortality with TB-HIV coinfection was recorded, with an increase in new cases in people living with AIDS among Aymara and Mapuche indigenous populations. Risk factors included CD4 < 500 cells/mm3 (HR = 3.2; 95%CI: 2.2-4.9), viral load at the start of treatment > 10,000 copies/uL (HR = 1.3; 95%CI: 1.2-1.6). Having high school or higher education (HR = 0.76; 95%CI: 0.6-0.9) is a protective factor for mortality for coinfection. Mortality was concentrated in TB-HIV coinfected people with increasing mortality among women and indigenous populations. The paper contributes to the growing recognition of the role of social determinants in disease outcomes, and the requirement to improve community-focused and community-based testing, sex education in schools, and structural interventions to reduce the adult mortality in Chilean population.

Objetivo: Analisar a associação entre as desigualdades sociais e sanitárias, condições socioeconômicas, segregação espacial e letalidade por COVID-19 em Fortaleza, Ceará, Brasil. Métodos: Estudo ecológico de casos confirmados e óbitos por COVID-19, tendo como unidades de análise os 119 bairros de Fortaleza. Objective: To analyze the association between social inequalities and sanitation, socioeconomic conditions, spatial segregation and case-fatality rate (CFR) due to COVID-19 in Fortaleza, Ceará, Brazil. Methods: Ecological study of confirmed cases and deaths due to COVID-19, in 119 neighborhoods in Fortaleza as units of analysis. We calculated the indicators of incidence, mortality and apparent CFR of COVID-19, between January 1 to June 8, 2020. The socioeconomic indicators were extracted from the Demographic Census of Brazil, 2010. Spatial analysis was performed and Moran´s Global and Local index were calculated. Results: We found 22,830 confirmed cases, 2,333 deaths and an apparent lethality of 12.7 (95%CI 11.6;13.9). We observed significant spatial autocorrelations for apparent CFR (I=0.35) and extreme poverty (I=0.51) that overlap in several neighborhoods in the city. Conclusion: Apparent CFR due to COVID-19 is associated with worse socioeconomic and sanitary conditions, demonstrating the relationship between social inequalities and health outcomes in times of pandemic.

Background Outbreaks of Chikungunya virus (CHIKV) occurred in Brazil during 2015–2017. Fortaleza was the city that reported the most cases. Methods The first round of a cohort study was conducted among women aged 15–39 y in Fortaleza, Brazil, in 2018 (Zika in Fortaleza). We collected sera to detect CHIKV IgG and IgM antibodies. Factors for CHIKV infection were identified using a Poisson regression model. Results We evaluated 1466 serum samples and 13.8% and 37.2% of women were found positive for CHIKV IgM and IgG antibodies, respectively. Living with more than four others in the same house and having an abandoned house nearby were associated with CHIKV infection. Being currently pregnant was associated with a decreased probability of CHIKV infection, which was also associated with pregnant women reporting using more repellent, both inside and outside the house, than non-pregnant women. Conclusions Crowding in households and abandoned houses nearby can increase potential transmission. Policies providing better living conditions and regulation of abandoned sites and buildings are necessary to control the mosquito population. Programmes providing repellant at low or no cost to pregnant women should be implemented in the neighbourhoods where arbovirus infections are endemic.
