Airborne Exposure to Pollutants and Mental Health: A Review with Implications for United States Veterans

PURPOSE OF REVIEW

Inhalation of airborne pollutants in the natural and built environment is ubiquitous; yet, exposures are different across a lifespan and unique to individuals. Here, we reviewed the connections between mental health outcomes from airborne pollutant exposures, the biological inflammatory mechanisms, and provide future directions for researchers and policy makers. The current state of knowledge is discussed on associations between mental health outcomes and Clean Air Act criteria pollutants, traffic-related air pollutants, pesticides, heavy metals, jet fuel, and burn pits.

RECENT FINDINGS

Although associations between airborne pollutants and negative physical health outcomes have been a topic of previous investigations, work highlighting associations between exposures and psychological health is only starting to emerge. Research on criteria pollutants and mental health outcomes has the most robust results to date, followed by traffic-related air pollutants, and then pesticides. In contrast, scarce mental health research has been conducted on exposure to heavy metals, jet fuel, and burn pits. Specific cohorts of individuals, such as United States military members and in-turn, Veterans, often have unique histories of exposures, including service-related exposures to aircraft (e.g. jet fuels) and burn pits. Research focused on Veterans and other individuals with an increased likelihood of exposure and higher vulnerability to negative mental health outcomes is needed. Future research will facilitate knowledge aimed at both prevention and intervention to improve physical and mental health among military personnel, Veterans, and other at-risk individuals.

Male Farm and Agricultural Worker Suicides in Kansas, 2016-2020

OBJECTIVES

There is limited research on the factors that contribute to suicides among farm and agriculture workers. The purpose of this analysis was to examine the socio-demographic characteristics and circumstances that may increase risk of suicide for a farm worker by using the detailed data from the Kansas Violent Death Reporting System (KS-VDRS).

METHODS

KS-VDRS is a state-based system and was used to look at suicides among farm and agricultural workers that occurred in Kansas from 2016 to 2020. Frequencies, percentages, and age-adjusted rates were calculated to compare trends between farm/agriculture workers and other major occupational groups (non-farm/agriculture). Females were not included in this analysis due to low counts in the occupational group.

RESULTS

In Kansas, male farm and agriculture workers die by suicide at a rate of 147.5 per 100,000 population, which is 3 times that of the average male workers (45.2 per 100,000 population). Male suicide decedents in farming and agriculture-related occupations were older with a mean age of 54 years and less educated (73% had a high school diploma or less) than their non-agriculture counterparts (mean age 44 years, and 57% had a high school diploma or less). Common circumstances around time of death were current depressed mood (58.6%), current mental health problem (41.4%), and physical health problem (31.4%).

CONCLUSION

KSVDRS provides valuable information on the circumstances surrounding suicides, and this can inform prevention efforts within and across states. Numerous factors may contribute to the increased risk of suicide among farmers and those who work in agriculture. Physical health problems, family relationship problems, and financial problems are more commonly reported among this population compared to other male workers. Findings from this report highlight the complexity of suicide risk within the farm and agriculture industry in Kansas and reinforce the need for state-specific data and tailored prevention efforts.

Stressor or succour? Examining the association between conflict, livestock assets, and farmers' mental health in Nigeria

Farmers are disproportionately vulnerable to violent attacks in the conflict situation in Nigeria, with potential traumatising effects due to the destruction of agricultural livelihoods. In this study, we conceptualise the links between conflict exposure, livestock assets, and depression, using a cross-sectional nationally representative survey of 3021 Nigerian farmers to quantify the relationships. We highlight three main findings. First, conflict exposure is significantly associated with farmers exhibiting depressive symptoms. Second, holding higher herds of livestock, more cattle, and more sheep and goats while exposed to conflict is associated with higher risk of depression. Third, keeping more poultry is negatively associated with depressive symptoms. Finally, this study accentuates the significance of psychosocial support for farmers in conflict situations. The relationships between different livestock species and farmers' mental health may interest further research in strengthening the evidence.

Effects of Temporary Respiration Exercise with Individual Harmonic Frequency on Blood Pressure and Autonomic Balance

This study investigated the effects of modulated respiration on blood pressure and autonomic balance to develop a healthcare application system for stabilizing autonomic balance. Thirty-two participants were asked to perform self-regulated tasks with 18 different respiration sequences, and their electrocardiograms (ECG) and blood pressure were measured. Changes in cardiovascular system functions and blood pressure were compared between free-breathing and various respiration conditions. Systolic and diastolic blood pressures stabilized after individual harmonic breathing. Autonomic balance, characterized by heart rate variability, was also stabilized with brief respiration training according to harmonic frequency. Five machine-learning algorithms were used to classify the two opposing factors between the free and modulated breathing conditions. The random forest models outperformed the other classifiers in the training data of systolic blood pressure and heart rate variability. The mean areas under the curves (AUCs) were 0.82 for systolic blood pressure and 0.98 for heart rate variability. Our findings lend support that blood pressure and autonomic balance were improved by temporary harmonic frequency respiration. This study provides a self-regulated respiration system that can control and help stabilize blood pressure and autonomic balance, which would help reduce mental stress and enhance human task performance in various fields.

Factors associated with common mental disorders among farmers in a medium-sized municipality in Northeastern Brazil

OBJECTIVE

To identify the prevalence and factors associated with common mental disorders among farmers living in a medium-sized municipality in Northeastern Brazil between 2019 and 2020.

METHODS

Trained interviewers applied the standardized questionnaire in 450 participants. Sociodemographic, health, income and working characteristics were assessed. The screening of common mental disorders was performed using the Self-Reporting Questionaire, with the cutoff point ≥ 7 for women and ≥ 5 for men. Poisson regression with robust estimation was applied to verify the prevalence ratios in the bivariate and multivariate analysis.

RESULTS

The prevalence of common mental disorders among farmers was 55.1% (95%CI: 50.4–59.6). The variables that remained significant and associated with common mental disorders were: men (PR = 1.7), > 60 years old (PR = 0.5), poor or very poor self-assessment of health (PR = 1.4), previous mental health treatment (PR = 1.2), alcohol abuse (PR = 1.2) and loss of production (PR = 1.3).

CONCLUSION

These results indicate that common mental disorders are associated with individual factors and with the farmers’ context of life and work, which shows the importance of social, economic and health services support to this group of workers.

Health-related quality of life within agriculture in England and Wales: results from a EQ-5D-3L self-report questionnaire

BACKGROUND

Mental and physical health problems among the farming community are well documented but there is limited evidence regarding the overall health status of this population. This paper offers a unique insight into this issue through presenting the findings from a survey instrument, the EQ-5D-3L, which provides a standardised measure of health-related quality of life (HRQOL).

METHODS

We conducted the largest ever survey (n = 15,296) of people living and working in agriculture in England and Wales to gather baseline data on health and wellbeing within this community. The survey included an assessment of HRQOL through the use of the EQ-5D-3L self-report questionnaire. A variety of statistical approaches were used to test for significant associations between HRQOL and sub-group characteristics, including the Chi-square test for independence, the Kruskal-Wallis test, and Mann-Whitney U-test. Binary logistic regression models were also created to assess the influence of a set of respondent characteristics on the likelihood of respondents reporting health problems in the EQ-5D-3L.

RESULTS

24% of respondents reported problems with mobility; 4% reported problems with self-care; 21% reported problems with performing their usual activities; 52% reported problems with pain/discomfort; and 31% reported problems with anxiety/depression. The mean EQ-5D index value was 0.811 (median (Md) 0.796, interquartile range (IQR) 0.275). The mean self-rated health score (EQ-VAS) was 77.6 (SD 16.1) (Md 80.0, IQR 20). In general, holding other respondent characteristics equal, women reported fewer problems with mobility, self-care, performing usual activities and pain/discomfort than men, but more problems with anxiety/depression. HRQOL in the working-aged appears to be poorer among the survey population than the wider UK population.

CONCLUSIONS

Results reveal concerning levels of physical and mental health problems, especially pain/discomfort and anxiety/depression, which appear to be more prevalent within our sample than within the wider UK population. There were important gender and age-related differences in both mental and physical health. Combatting these problems through targeted support is essential for the wellbeing of the farming community and the future sustainability of UK food production.

Analysis of Factors Associated with the Risk of Suicide in a Brazilian Capital: Cross-Sectional Study

Suicide and suicide attempts are considered global health problems. With regard to the main causes of unnatural deaths, Brazil ranks as the eighth country with the highest absolute number of suicides. The aim of this study was to analyze the factors associated with the risk of suicide in a metropolitan city in Brazil. This was a cross-sectional study carried out in Recife, in the northeast region of Brazil. Epidemiological surveillance was conducted on the information systems regarding attempted suicide, suicide, and undetermined deaths in the period from 2007 to 2017. A record linkage between the information systems was performed. Descriptive statistics, bivariate analysis, and logistic regression were performed with an adopted a significance level of 5%. In the city of Recife, there were 4495 suicide attempts in the period, and the most frequent suicide attempts were by single females, aged between 20 and 39 years old, and who used either medication or poison to die by suicide. A total of 141 individuals died by suicide, and exogenous intoxication was the most common method. Knowing the common characteristics and associated factors of those who attempt and die by suicide is key for the development of prevention policies and intervention strategies for suicide.
