Suicide burden in Latin America, 1990–2019: findings from the Global Burden of Disease Study 2019

Excess suicides in Brazil during the first 2 years of the COVID-19 pandemic: Gender, regional and age group inequalities

BACKGROUND

While the COVID-19 pandemic's total impact on global mortality is uncertain, an estimated 15 million excess deaths occurred during the first two pandemic years, suggesting that a broad impact, since several causes of death showed a substantial rise.

AIMS

To estimate excess suicides in Brazil and evaluate differences within and between subgroups during the first 2 years of the COVID-19 pandemic.

METHOD

Based on suicide data from the mortality information system of the Brazilian Ministry of Health, the expected number of suicides was estimated by age group, gender, 4-month periods and regions through quasi-Poisson generalized additive models. Analyses were performed in R software and RStudio.

RESULTS

Between March 2020 and February 2022, 29,295 suicides were reported in Brazil, close to what would be expected (30,116; 95% Confidence Interval (95% CI): [28,009, 32,224]), albeit in males and females aged 30 to 59 years and 60 years and over, there were excess suicides in at least one of the six 4-month periods evaluated, especially in the second pandemic year. In the Southeast region, a 28% increase was observed in women 60 years and older during the second year. In the North region, suicide increased 23% and 32% among women aged 30 to 59 years during the first and second pandemic years, respectively. The Northeast region had a 16% excess in suicides among men aged 30 to 59 years and 61% among women 60 years old and older during the second pandemic year, reaching 83% in July to October 2021.

CONCLUSIONS

During the first 2 pandemic years, the pattern of suicides was not homogeneous in Brazil. There were substantial excess suicides in women aged 30 to 59 years from the North and Northeast, while among the elderly and men there was a consistent pattern in several four-month periods throughout Brazil.

Sexual orientation disparities in the prevalence of suicidal ideation among U.S adults aged 20 to 59 years: Results from NHANES 2005-2016

Existing studies have been limited in providing nationally representative data on the relationship between sexual orientation and suicidal ideation (SI) among adults in the U.S. particularly in terms of gender and racial differences. To fill this research gap, we conducted a study using data from the NHANES conducted between 2005 and 2016. Survey-weighted logistic regression models were used to investigate the relationship between sexual orientation and SI risk. Additionally, we performed further analysis by stratifying the data based on demographic variables and performed sensitivity analysis to ensure the reliability of our findings. This study included a weighted sample of 16,564 adults, representing a noninstitutionalized U.S population of 840.1 million. The overall age-adjusted prevalence of SI was found to be 3.5 %. After adjusting for relevant covariates, the study revealed that individuals who identified as something else, homosexual, and bisexual had a higher prevalence risk of suicidal ideation (SI) compared to heterosexual participants. Additionally, the study found that heterosexual participants were 74.4 % less likely to experience SI compared to bisexual individuals. These findings highlight the urgent requirement for inclusive and supportive prevention strategies to effectively address SI among adult sexual minorities in the U.S.
