Key Risk Factors Affecting Farmers' Mental Health: A Systematic Review

Recently, concern has increased globally over farmers' mental health issues. We present a systematic review of the outcomes, locations, study designs, and methods of current studies on farmers' mental health. In particular, this review aims to fill an important gap in understanding of the potential key risk factors affecting farmers' mental health around the world. 167 articles on farmer mental health were included in a final systematic review using a standardized electronic literature search strategy and PRISMA guidelines. The four most-cited influences on farmers' mental health in the reviewed literature respectively were pesticide exposure, financial difficulties, climate variabilities/drought, and poor physical health/past injuries. The majority of studies were from developed countries, most specifically from the United States, Australia, and the United Kingdom. Comparative studies on the mental health of farmers and other occupational workers showed mixed results, with a larger portion identifying that psychological health disturbances were more common in farmers and farm-workers. Knowledge of farmer psychological disorder risk factors and its impacts are essential for reducing the burden of mental illness. Further research will be required on climate change impacts, developing country farmers' mental health, and information on how to reduce help-seeking barriers amongst farmers.

The impact of depressive symptoms on exit from paid employment in Europe: a longitudinal study with 4 years follow-up

Background

Mental health problems are a risk factor for loss of paid employment. This study investigates (i) the relation between depressive symptoms and different involuntary pathways of labour force exit and (ii) explores gender and geographical differences in this relation.

Methods

The study population consisted of 5263 individuals in paid employment aged between 50 years and the country-specific retirement age from 11 European countries participating in the longitudinal Survey of Health, Ageing and Retirement in Europe (SHARE). Self-reported depressive symptoms at baseline were assessed using the EURO-D. Employment status was derived from interviews after 2 and 4 years. Cox proportional hazards regression analyses were used to investigate the association between depressive symptoms and labour force exit via disability benefit and unemployment. Population attributable fractions (PAFs) were calculated to estimate the contribution of depressive symptoms to these pathways of labour force exit.

Results

Both men and women with a EURO-D score ≥4 had a >2-fold increased risk of a disability benefit (HR: 2.46, 95%CI 1.68–3.60) after adjustment for demographics and work-related characteristics. Among men depressive symptoms elevated the risk of becoming unemployed at follow-up (HR 1.55; 95%CI: 0.94–2.57). The PAF was 0.18 for disability benefit and 0.04 for unemployment, and varied across European regions.

Conclusions

Individuals with depressive symptoms are at increased risk of losing paid employment, which in turn may aggravate their symptoms. Targeting depressive symptoms with public health and occupational policies should be considered to reduce the burden of mental diseases in Europe.

Mental Health and Disability Pension Onset: Changes in Consumption of Antianxiety and Hypnotic Drugs

Introduction:

In Norway, disability pension (DP) has been more prevalent over the later years, with mental disorders being a frequent cause. Previous analyses have questioned whether receiving DP is beneficial for mental health by considering changes in antidepressant drug consumption. To explore this further, we examined changes in antianxiety and hypnotic drug consumption following DP onset.

Methods:

Based on national Norwegian register data, this retrospective study encompassed 8617 working-age individuals (25-50 years) who became DP during 2005 to 2013. We compared their benzodiazepines (BZD) and Z-hypnotic consumption 1 year pre- and postdisability pension onset.

Results:

About 80% of the individuals did not change their altogether benzodiazepine/Z-hypnotic consumption. Among individuals with an initial consumption ≤1 defined daily dose (DDD), 18.9% increased their consumption to above 1 DDD. Individuals in the age-group 45 to 50 versus 24 to 34 years had a lower risk of dose escalation (odds ratio [OR], 0.756, 95% confidence interval [CI]: 0.601-0.957). Individuals who used Z-hypnotics only had a higher risk of dose escalation compared to the joint benzodiazepine/Z-hypnotic user group (OR, 1.594, 95%CI: 1.284-1.970).

Conclusion:

In general, we cannot see that DP is associated with changes in benzodiazepine/Z-hypnotic consumption, but younger users and individuals using Z-hypnotics only had a greater risk of dose escalation compared to the older users and users with combined BZD and Z-hypnotic use.
