Suicidal thought in southern Brazil: Who are the most susceptible?

The global burden of suicidal behavior among people experiencing food insecurity: A systematic review and meta-analysis

BACKGROUND

Food insecurity has become a growing burden within a global context where climate change, catastrophes, wars, and insurgencies are increasingly prevalent. Several studies have reported an association between suicidal behaviors (i.e., suicide ideation, plans, and attempts) and food insecurity. This meta-analytic review synthesized the available literature to determine the pooled prevalence of suicidal behaviors among individuals experiencing food insecurity, and examined the strength of their association.

METHODS

Databases (Ovid, PubMed, Web of Science, and CINAHL) were searched from inception to July 2022 using appropriate search terms. Eligible studies reporting the number/prevalence of suicidal behaviors among individuals experiencing food insecurity or the association between food insecurity and suicidal behaviors were included. The pooled prevalence of suicidal behaviors was determined using the random-effects model. The review was registered with PROSPERO (CRD42022352858).

RESULTS

A total of 47 studies comprising 75,346 individuals having experienced food insecurity were included. The pooled prevalence was 22.3 % for suicide ideation (95 % CI: 14.7-29.9; I2 = 99.6 %, p < 0.001, k = 18), 18.1 % for suicide plans (95 % CI: 7.0-29.1; I2 = 99.6 %, p < 0.001, k = 4), 17.2 % for suicide attempts (95 % CI: 9.6-24.8; I2 = 99.9 %, p < 0.001, k = 12), and 4.6 % for unspecified suicidal behavior (95 % CI: 2.8-6.4; I2 = 85.5 %, p < 0.001, k = 5). There was a positive relationship between experiencing food insecurity and (i) suicide ideation (aOR = 1.049 [95 % CI: 1.046-1.052; I2 = 99.6 %, p < 0.001, k = 31]), (ii) suicide plans (aOR = 1.480 [95 % CI: 1.465-1.496; I2 = 99.1 %, p < 0.001, k = 5]), and (iii) unspecified suicide behaviors (aOR = 1.133 [95 % CI: 1.052-1.219; I2 = 53.0 %, p = 0.047, k = 6]). However, a negative relationship was observed between experiencing food insecurity and suicide attempts (aOR = 0.622 [95 % CI: 0.617-0.627; I2 = 98.8 %, p < 0.001, k = 15]). The continent and the countries income status where the study was conducted were the common causes of heterogeneity of the differences in the odds of the relationships between experiencing food insecurity and suicidal behaviors - with North America and high-income countries (HICs) having higher odds. For suicide attempts, all non HICs had a negative relationship with food insecurity.

LIMITATIONS

There was significant heterogeneity among the included studies.

CONCLUSION

There is a high prevalence of suicidal behaviors among individuals experiencing food insecurity. Initiatives to reduce food insecurity would likely be beneficial for mental wellbeing and to mitigate the risk of suicidal behaviors among population experiencing food insecurity. The paradoxical finding of suicide attempts having a negative relationship with food insecurity warrants further research.

Firearm-related suicides, homicides, and homicide-suicides involving security officers in two East African Countries: a press media review

BACKGROUND

Firearm violence is a growing public health problem causing death globally. With easy accessibility to firearms, suicides, homicides, and homicide-suicides have increased among security officers, especially in developing countries affected by long-standing civil wars/political insurgencies. No study has explored firearm violence in East African countries. This study describes the press media reporting of suicides, homicides, and homicide-suicides among security officers in two East African countries (Uganda and Kenya).

METHODS

Due to the absence of suicide databases among East African countries, the present study reviewed press media reports. We utilized content analysis of suicides, homicides, and homicide-suicides reports among security forces. Relevant media reports between January-2020 and May-2023 were searched. Using ANOVA and chi-square tests, we tested for statistical differences in characteristics between victims and perpetrators.

RESULTS

Among the 56 perpetrated reports, most of them were homicides 44.64% (n = 25/56), 30.36% (n = 17/56) were homicide-suicides, and 25% (n = 14/56) were suicides. Perpetrators' age ranged from 21 to 47 years, majority being males [53/56 (94.64%)]. Victims were 58, mostly Ugandans [41/58 (73.21%)] with a mean age of 33.5 ± 8.81 years. Among the three main outcomes, statistically significant difference existed by country (χ2 = 23.88, p < 0.001), and perpetrators' age (F = 8.59, p = 0.005). There was a significant difference between perpetrators and the number of victims lost by age of victims (F = 10.37, p = 0.002). Among victims, type of security of perpetrator and citizenship of victims (χ2 = 24.18, p < 0.001) showed statistical difference with Ugandans having more victims to army officers while Kenyans to police officers. Brief incident descriptions pointed towards relationship dysfunctions, alcohol/substance abuse, intentional harm, and financial disagreements, as the potential causes. Only two perpetrators were reported to have mental health-related conditions.

CONCLUSION

This study shows that media reported firearms-related suicides, homicides, and homicide-suicides among security forces commonly involve males. Perpetrators in Uganda are mainly army officers while in Kenya the perpetrators are mostly police officers. Mental health conditions were not frequently reported among perpetrators. We recommend strengthening and enforcing gun regulation policies among security officers to curb this growing problem in these countries. Routine screening of mental health problems to enable early interventions is recommended among security officers.

Food Insecurity and Suicidal Behaviors Among US High School Students

BACKGROUND

Food insecurity (FI) rates in the United States are particularly high among households with children. This research set aims to analyze if high school students experiencing FI had higher risk for mental health and suicidal behaviors.

METHODS

Using combined data from 11 states that conducted the 2017 Youth Risk Behavior Survey, a total of 26,962 and 24,051 high school students were used to estimate race/ethnicity and sex-stratified prevalence ratios (PRs) from Poisson regression models. A single-question was used to measure the exposure of FI and outcomes of mental health and suicidal behaviors.

RESULTS

Overall, 10.8% of students reported FI. Students experiencing FI had increased risk for all mental health and suicide behavior outcomes, regardless of their race/ethnicity or sex. PRs ranged from 1.9 (95% confidence interval [CI]:1.8, 2.0) to 3.1 (CI: 2.7, 3.6). Among males, PRs for the association between FI and all outcomes were highest among non-Hispanic black students (PRs ranged from 2.4 [CI: 1.7, 3.2] to 5.5 [CI: 2.3, 13.3]). Among females, PRs were highest among non-Hispanic white students (PRs ranged from 1.9 [CI:1.7, 2.1] to 3.6 [CI:2.9, 4.5]).

CONCLUSIONS

FI is consistently associated with mental health and suicidal behaviors among different subgroups of students.

Association between food insecurity and major depressive episodes amid Covid-19 pandemic: results of four consecutive epidemiological surveys from southern Brazil

OBJECTIVE

To assess the association between household food insecurity (FI) and major depressive episodes (MDE) amid Covid-19 pandemic in Brazil.

DESIGN

Cross-sectional study carried out with data from four consecutive population-based studies.

SETTING

The study was conducted between May and June 2020, in Bagé, a Brazilian southern city. Household FI was measured using the short-form version of the Brazilian Food Insecurity Scale. Utilising the Patient Health Questionnaire-9, we used two different approaches to define MDE: the cut-off point of ≥ 9 and the diagnostic criteria proposed by the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR). Association between FI and MDE was analysed using crude and adjusted Poisson regression models.

PARTICIPANTS

1550 adults (≥ 20 years old).

RESULTS

The prevalence of household FI was 29·4 % (95 % CI 25·0, 34·4). MDE prevalence varied from 4·4 % (95 % CI 3·1, 6·0), when we used the DSM-IV-TR criteria to define this condition, to 9·6 % (95 % CI 7·3, 12·5) of the sample, when we used the cut-off point of ≥ 9 as definition. The prevalence of MDE was more than two times higher in those individuals living with FI, independent of the criteria adopted to define the outcome. Adjustment for potential confounders did not change the association's magnitude.

CONCLUSIONS

Household FI has been positively associated with MDE amid Covid-19 pandemic, independent of socio-demographic characteristics of participants. Actions are needed to warrant basic living conditions to avoid FI and hunger and its consequences for the Brazilian population, especially those consequences linked to mental health disorders.

Prevalence and Associated Risk Factors of Suicidal Ideation Among Brazilian Pregnant Women: A Population-Based Study

BACKGROUND

Suicide is a leading cause of death during the perinatal period in high-income countries (HIC). There remains a lack of population-based studies about suicidal ideation (SI) during pregnancy among low and middle income countries (LMIC).

OBJECTIVES

Using the case of Brazil, we aim to estimate the prevalence of SI during pregnancy and its association with antenatal depression (AD) and sociodemographic factors in a LMIC.

METHOD

We used data from the Brazilian National Survey (PNS-2019), a population-based study, with a complex and probabilistic sampling method. Of the 27,136 women of reproductive age (15 to 49 years old) who participated in the PNS, a total of 769 women reported being pregnant at the time of the interview. All PNS participants answered the Patient Health Questionnaire-9 (PHQ-9) and a questionnaire with sociodemographic data. SI was defined as any answer to the PHQ-9 item 9 other than 0 (not at all). Logistic regression models were performed to obtain crude and adjusted odds ratios (aOR) and 95% confidence intervals (95% CI) for the association between explanatory variables and SI during pregnancy.

RESULTS

Among 769 women, 33 (3.9%, 95% CI: 3.0-5.1%) reported SI during pregnancy. In the adjusted analysis, higher odds of SI were associated with being 20 to 34 years old (aOR:0.24, 95% CI: 0.08-0.74) or 35 to 49 years old (aOR:0.15; 95% CI: 0.04-0.50), having 9 to 11 years of education (aOR 0.23, 95% CI: 0.61-0.86), acheiving the highest family income category (aOR:0.08, 95% CI: 0.01-0.58), not living in the South/Southeast regions of Brazil (aOR:5.52, 95% CI: 2.36-12.9), and having probable mild AD (aOR:10.5 95% CI: 2.3-47.9) or moderate AD (aOR:241.3, 95% CI: 58.4-996.7).

CONCLUSIONS

In Brazil, SI affects almost 4% of pregnant women and is associated with sociodemographic vulnerability. Clinically, women with mild symptoms of depression may also experience SI during pregnancy. These findings are important for designing effective perinatal mental health interventions in LMICs.

Factors associated with suicide ideation of healthcare university students

ABSTRACT Objectives: to analyze the factors associated with suicidal ideation in students from healthcare graduation courses. Methods: quantitative, cross-sectional study, with 251 students from the courses of radiology, speech-language therapy, medicine, nutrition, health service management, and nursing, from a federal higher education institution in the Southeast of Brazil. Data were collected from August to October 2019, using an electronic questionnaire. Results: the prevalence of suicidal ideation among participants was 26.33%. In the final logistic regression model, only depressive symptoms were associated with suicidal ideation. Having symptoms of depression increased the chances of suicidal ideation 2.6 times. Conclusion: the high prevalence of suicidal ideation and its associated factors constitutes a situational diagnosis that demands the elaboration of public and institutional policies, focused on the promotion and attention to the mental health of the students.

Psychological and financial impact of the COVID-19 pandemic during the first stages of the pandemic: Brazilian orthodontists´ perspective

Introduction:

Brazil faced a catastrophic situation in the coronavirus pandemic. Due to the high risk of contamination and spread of COVID-19, dentist have been attending only urgency and emergency services in Brazil at the beginning of the pandemic.

Objective:

This research aimed to evaluate the psychological and financial impacts caused by the coronavirus pandemic in Brazilian orthodontists.

Methods:

This population-based cross-sectional study collected demographic data and mental health measurements from 404 orthodontists. Depression, anxiety, insomnia, and distress were evaluated through Brazilian versions of the 9-item Patient Health Questionnaire (9-PHQ), the 7-item Generalized Anxiety Disorder scale and Mini-Tracking (GAD), the 7-item Insomnia Severity Index (ISI), and the 22-item Impact of Event Scale-Revised (IES-R), respectively. The demographic data of the sample was described using descriptive statistics. The data was analyzed according to sex, professional status, and economic income. Comparisons were performed using Chi-square tests, Mann-Whitney U tests, and Kruskal-Wallis followed by post-hoc tests.

Results:

Females, graduate students, and lower incomes subgroups showed higher levels of depression, anxiety, insomnia, and distress. Most orthodontists showed moderate to extreme financial and professional concerns during the pandemic.

Conclusion:

The coronavirus pandemic negatively affected the psychological health and increased the financial concerns of the Brazilian orthodontists, mainly female, graduate students, and with income below 10k participants.

Prevalence of anxiety, depression and suicidal behaviors among Brazilian undergraduate students: A systematic review and meta-analysis

BACKGROUND

The university context can be an overwhelming background, being especially harmful to undergraduates' mental health. Considering that several studies have reported on the prevalence of psychological distress among Brazilian undergraduate students, this study aimed to conduct a systematic review and meta-analysis of the prevalence and associated factors of anxiety, depression and suicidal behavior in this population.

METHODS

Studies reporting on the prevalence of anxiety, depression and suicidal behavior and its associated factors among Brazilian undergraduate students were systematically searched in scientific electronic databases. Pooled prevalence was calculated using a random-effects meta-analysis. Individual associated factors were summarized, and study characteristics associated with outcome prevalence were tested through meta-regression analysis.

RESULTS

Forty-seven articles were included, of which 44 were meta-analyzed (37,486 undergraduates). The pooled prevalence estimates of anxiety, depression and suicidal behavior were 37.75%, 28.51%, and 9.10%, respectively. Meta-regression analysis showed that investigations with probabilistic samples presented a higher prevalence of anxiety and that studies conducted within public institutions and with samples of exclusively medical students presented higher frequencies of depression.

LIMITATIONS

Cross-sectional data do not allow the establishment of temporality and causal inference. Furthermore, the high heterogeneity of the included studies may also constitute a weakness of this review.

CONCLUSIONS

The prevalence of anxiety, depression and suicidal behavior among Brazilian undergraduates was high. These results have scientific and practical implications, the former regarding the need for the standardization of the methodology of studies and the latter regarding the need for comprehensive mental health care for Brazilian undergraduates.

Comparison of causes for suicidal ideation and attempt: Korean Longitudinal Survey of Women and Families

The purpose of this study was to identify factors that influence suicidal ideation and attempts among Korean women, using longitudinal data. Data from wave 4 (n = 7227), wave 5 (n = 6892), and wave 6 (n = 6632) of the Korean Longitudinal Survey of Women and Families collected on 2012, 2014, and 2016 were subjected to Kaplan-Meier and Cox regression analysis. Number of cases for suicidal ideation was 4.7% of the total cases (n = 20,751) between wave 4 through 6; number of cases for suicidal attempts was 5.7% of the cases from suicide ideation (n = 979). Depressive feelings, bad or worst health, and increased stress had significant impacts on suicidal ideation (χ² = 1867.84, p < .001; χ² = 983.61, p < .001; χ² = 884.01, p < .001) and suicidal attempts (χ² = 5.36, p < .05; χ² = 11.19, p < .01; χ² = 7.46, p < .05; χ² = 6.21, p < .05) over time, respectively. From the Cox regression analysis, non-marital status (OR = 2.50, CI = 1.40-4.48) and having more than two children (OR = 2.55, CI = 1.18-5.51) compared to not having children were identified as predictors for suicidal attempt. Although the negative effect of number of children on suicidal attempts conflicts with previous evidence, socially determined mother roles and the significance of children should be considered in culturally sensitive terms when interpreting our findings.

Perinatal suicidality: Risk factors in South African women with mental illness

Background

Maternal Mortality is a global health concern. The lack of suicide data, particularly in low and middle income countries, is concerning and needs to be addressed.

Aim

This study assessed suicidality and associated factors during pregnancy and the postpartum period amongst women with known psychiatric diagnoses.

Setting

The study sample included pregnant South African women over the age of 18 years with a psychiatric disorder who presented at two maternal mental health clinics.

Method

Suicidality was assessed by means of psychiatric interviews - the Mini International Neuropsychiatric Interview and the Montgomery Asberg Depression Rating Scale.

Results

The results revealed that women were at a higher risk of experiencing suicidality if they had attempted suicide before, presented at a later gestation for psychiatric care or were employed. It was also clear that multiple assessments, carried out by means of clinical interviews and various scales, were necessary to screen suicidality successfully in pregnant women diagnosed with psychiatric illness.

Conclusion

The results confirmed the view of the World Health Organization that in order to promote mental health and well-being, women's health should be viewed contextually, not in isolation. Screening for and treatment of perinatal mental illness, including suicidality, are essential if we hope to meet the maternal morbidity and mortality targets of the United Nations by 2030.
