Effect of alcohol use disorders and alcohol intake on the risk of subsequent depressive symptoms: a systematic review and meta-analysis of cohort studies

Schoolteachers with voice handicap are twice as likely to report depressive symptoms

This study aimed to examine the association between voice disorder and depressive symptoms in schoolteachers. A cross-sectional survey was conducted with elementary and secondary schoolteachers. Voice disorders and depressive symptoms were assessed with the Voice Handicap Index-10 and the Beck Depression Inventory-II, respectively. Logistic and linear regressions models were adjusted for confounding variables. In the 389 schoolteachers studied, the prevalence of voice handicap and depressive symptoms was 18.8 and 38.8%, respectively. Voice handicap was associated with depressive symptoms on all models tested. The logistic regression showed an odds ratio of 2.21 (95% confidence interval: 1.19, 4.08; p value < 0.05), while in the linear regression each point increase on the voice disorder scale increased the Beck Depression Inventory-II score by 0.39 points (95% confidence interval: 0.26, 0.54; p value < 0.05). This study showed that teachers of public schools with voice handicap are twice as likely to report depressive symptoms.

Longitudinal reciprocal associations between depression, anxiety, and substance use disorders over three decades of life

BACKGROUND AND OBJECTIVE

Studies exploring longitudinal reciprocal associations between depressive, anxiety, and substance use disorders (DD, AD and SUD, respectively) over long periods of time are mainly lacking. Therefore, the aim of the present study is to test longitudinal associations (i.e. temporal dynamics) between DD, AD and SUD from young adulthood to middle adulthood.

METHODS

A stratified community sample of 591 participants from the canton of Zurich, Switzerland, was interviewed with the Structured Psychopathological Interview and Rating of the Social Consequences of Psychological Disturbances for Epidemiology over seven interview waves from ages 20/21 to 49/50. Diagnostic and Statistical Manual of Mental Disorders criteria were used to evaluate the presence of DD, AD and SUD. We fitted an auto-regressive cross-lagged path analysis within a Bayesian structural equation model to test longitudinal associations.

RESULTS

Regarding autoregressive effects, AD (except during young adulthood) and SUD predicted themselves over the entire time period, while DD recurrently predicted itself not consistently over time. Regarding cross-lagged effects, DD predicted SUD at different time points, and vice versa. DD predicted subsequent AD in adulthood, whereas the reverse did not happen. Female gender was associated with DD and AD at all ages while male gender was associated with SUD only in young adulthood.

CONCLUSIONS

Reciprocal longitudinal associations were found between DD and SUD and DD usually preceded AD. Our results further confirm an increased risk of DD and AD in women and a higher risk of SUD in young men. Early treatment and broad psychosocial interventions should be provided in order to prevent chronicity and further maladjustment as well as interrupting the cycle of mutual reinforcement between DD and SUD.

Socioeconomic status, alcohol use disorders, and depression: A population-based study

BACKGROUND

Depressive disorders (DD) and alcohol use disorders (AUD) frequently co-occur. They are key to understanding the current increases in "deaths of despair" among individuals with lower socioeconomic status (SES). The aim of this study was to assess the prospective bidirectional associations between AUD and DD, as well as the effect of SES on these two conditions.

METHODS

The National Epidemiologic Survey on Alcohol and Related Conditions is a cohort study representative of the US adult population, which began in 2001-2002, with follow-up interviews conducted 3 years later. SES was primarily operationalized as educational attainment. AUD, DD, and their levels of severity were defined according to the DSM-5 criteria.

RESULTS

The risk of developing an incident DD increased gradually with the recency and the severity of AUD at baseline, but the converse was not observed. Lower SES was an independent risk for incident AUD or DD. SES did not modify the prospective association between AUD and DD.

LIMITATIONS

The absence of interaction between SES and moderate or severe AUD for the incident DD must be considered with caution due to the limited number of DD cases reported in these AUD categories.

CONCLUSIONS

This result is consistent with a causal relationship between AUD and DD, and suggests that therapeutic interventions for AUD may also have beneficial effects to lower DD rates. The independent effects of a lower SES and AUD on DD may result in a vulnerable population cumulating disorders with heavy consequences on health and social well-being.

Are there non-linear relationships between alcohol consumption and long-term health?: a systematic review of observational studies employing approaches to improve causal inference

Background

Research has long found ‘J-shaped’ relationships between alcohol consumption and certain health outcomes, indicating a protective effect of moderate consumption. However, methodological limitations in most studies hinder causal inference. This review aimed to identify all observational studies employing improved approaches to mitigate confounding in characterizing alcohol–long-term health relationships, and to qualitatively synthesize their findings.

Methods

Eligible studies met the above description, were longitudinal (with pre-defined exceptions), discretized alcohol consumption, and were conducted with human populations. MEDLINE, PsycINFO, Embase and SCOPUS were searched in May 2020, yielding 16 published manuscripts reporting on cancer, diabetes, dementia, mental health, cardiovascular health, mortality, HIV seroconversion, and musculoskeletal health. Risk of bias of cohort studies was evaluated using the Newcastle-Ottawa Scale, and a recently developed tool was used for Mendelian Randomization studies.

Results

A variety of functional forms were found, including reverse J/J-shaped relationships for prostate cancer and related mortality, dementia risk, mental health, and certain lipids. However, most outcomes were only evaluated by a single study, and few studies provided information on the role of alcohol consumption pattern.

Conclusions

More research employing enhanced causal inference methods is urgently required to accurately characterize alcohol–long-term health relationships. Those studies that have been conducted find a variety of linear and non-linear functional forms, with results tending to be discrepant even within specific health outcomes.

Alcohol and other substance use during the COVID-19 pandemic: A systematic review

BACKGROUND

Although evidence suggests substance and alcohol use may change during the Covid-19 pandemic there has been no full review of the evidence around this.

METHODS

A systematic review of all available evidence was carried out to document and interpret the frequency and severity of alcohol and other substance use during the Covid-19 pandemic and their relationship to demographic and mental health variables that may suggest further clinical implications. Peer reviewed articles in MEDLINE, Embase, PsycINFO, CINAHL complete and Sociological Abstracts were searched from December 2019 until November 2020.

RESULTS

The search and screening identified 45 articles from 513 deduplicated records. The evidence suggests a mixed picture for alcohol use. Overall, there was a trend towards increased alcohol consumption. The proportion of people consuming alcohol during the pandemic ranged from 21.7% to 72.9% in general population samples. Unlike alcohol use, there was a clear trend towards increased use of other substances use during the COVID-19 pandemic. The proportion of people consuming other substances during the pandemic ranged from 3.6% to 17.5% in the general population. Mental health factors were the most common correlates or triggers for increased use of both alcohol and other substances.

CONCLUSION

There is an increased need for treatment for alcohol and other substance use related problems during the pandemic. Increased targeting and evidence-based interventions will also be important in the period which follows this pandemic, to improve the quality of life for individuals and families, but also to prevent additional costs to society and health systems.

Symptoms of major depressive disorder during the COVID-19 pandemic: results from a representative sample of the Canadian population

INTRODUCTION

Since the outbreak of COVID-19, numerous studies from around the world have reported declines in mental health. However, most of these studies were of low-to-moderate quality and many were based on convenience samples or used mental health measures with low validity, or both. Consequently, it has been difficult to draw conclusions.

METHODS

Both the 2020 Survey on COVID-19 and Mental Health (SCMH) and the Canadian Community Health Survey (CCHS) (2015-2019) used the Patient Health Questionnaire-9 to screen for major depressive disorder (MDD) in adults aged 18 or older. The prevalence of MDD was compared between the SCMH and the CCHS. Risk and protective factors for MDD in the SCMH were examined using bivariate and logistic regression analyses.

RESULTS

Based on SCMH data, 15.2% (95% CI: 14.2-16.2) of Canadians screened positive for MDD. The prevalence of MDD was more than two times higher in the SCMH (during COVID-19) than in the CCHS (predating COVID-19). In bivariate analysis, Canadians reporting five or more COVID-19-related risk factors were close to 30 times more likely to have MDD than those reporting no risk factors. Mastery and a sense of community belonging were protective factors for MDD.

CONCLUSION

After remaining stable for two decades, the prevalence of depression among Canadians increased substantially with the onset of COVID-19. Ongoing monitoring of this common condition associated with major morbidity is vital to determine if elevated levels of MDD persist as we progress through and beyond future waves of COVID-19.

Cannabis and binge alcohol use among older individuals with major depressive episode

BACKGROUND

Research shows significant associations of major depression with cannabis and binge alcohol use. However, despite increasing cannabis and binge alcohol use rates among the 50+ age group, research on this age group is scant. Methods: We used the 2015-2019 National Survey on Drug Use and Health data (n = 44,007 age 50+) and multinomial logistic regression models to examine associations of a major depressive episode (MDE) with cannabis and binge alcohol use and co-use and associations of binge alcohol use with nonmedical and medical cannabis use. Results: Of individuals age 50+, 89.6% had no history of MDE, 5.7% had prior-to-past-year MDE, and 4.7% had past-year MDE. The rates of past-month cannabis use were 4.3%, 7.7%, and 11.6% and binge alcohol use were 17.3%, 18.7%, and 19.9% among those with no MDE history, prior-to-past-year MDE, and past-year MDE, respectively. Compared to no MDE history, prior-to-past-year MDE (RRR = 1.70, 95% CI = 1.30-2.23) and past-year MDE (RRR = 1.80, 95% CI = 1.27-2.55) were significantly associated with past-month cannabis use (with or without binge alcohol use). However, MDE status was not associated with past-month binge alcohol use. Among cannabis users, binge alcohol use was significantly associated with nonmedical cannabis use only (RRR = 2.50, 95% CI = 1.95-3.21). Users of cannabis and/or binge alcohol also had a higher likelihood of using tobacco products and illicit drugs. Conclusions: Healthcare professionals treating individuals age 50+ with depression should screen for substance use, provide education on the potential adverse effects of polysubstance use, and help them access treatment for co-occurring depression and substance use problems.

The Association Between Alcohol Use and Suicidal Ideation Among Employees

OBJECTIVE

The risk of suicide is assessed by identifying the relationship between alcohol-use patterns and suicidal ideation in Korean employees.

METHODS

The study involved 13,858 employees who underwent workplace mental health screening at the Workplace Mental Health Institute of Kangbuk Samsung Hospital over a 6-year period between 2014 and 2019. Analysis was performed separately for Alcohol Use Disorders Identification Test-Korea (AUDIT-K) items related to the frequency/volume of alcohol consumption (items 1 to 3, AUDIT-C) and those regarding alcohol dependence/related problems (items 4 to 10, AUDIT-D/P). Subjects were then classified into three groups on the basis of the presence or absence of clinical depression and suicidal ideation. The groups' sociodemographic factors and clinical features of depression, anxiety, and alcohol-use patterns were analyzed with a chi-square test as well as one-way analysis of variance, followed by a post hoc test using the Bonferroni correction.

RESULTS

AUDIT-K and AUDIT-D/P scores were significantly associated with the presence or absence of clinical depression as well as the presence or absence of suicidal ideation (p<0.05). However, no significant differences were found among the three groups with regard to the AUDIT-C score (p=0.054).

CONCLUSION

Identifying or treating alcohol dependence/related problems can help lower the occurrence of mental health problems, and suicidal ideation in particular, in employees and reduce social costs.

Alcohol drinking, especially light drinking, and depressive symptoms in adolescents

BACKGROUND

The association of depressive symptoms with moderate and heavy drinking in adolescents have been reported in many studies, but that with light drinking is unclear.

METHODS

In a 2012-13 school-based survey, 20,951 secondary school students (aged 11-20 years, 51.3 % boys) from 44 schools in Hong Kong reported their sociodemographic information, depressive symptoms, drinking patterns and other lifestyle factors. The associations of depressive symptoms with drinking status, drinking frequency and quantity, and the usual type of alcohol beverage consumed were examined using robust Poisson regression accounting for school clustering and covariates.

RESULTS

The prevalence of current drinking and depressive symptoms was 13.6 % and 19.0 %, respectively. Depressive symptoms were associated with former drinking (adjusted prevalence ratio 1.48, 95 % confidence interval 1.30-1.68) and measures of light drinking: experimental drinking (1.29, 1.19-1.39), less-than-monthly drinking (1.40, 1.18-1.67) and consuming half a drink or less (1.33, 1.12-1.58), and such associations were stronger in younger adolescents. Associations were also observed for light drinking patterns of 1-2 drinks less than monthly (1.72, 1.40-2.11) and half a drink monthly (1.51, 1.21-1.88). Consuming fruit wine (1.51, 1.27-1.79) and beer (1.63, 1.42-1.88) with relatively low alcohol contents was also associated with depressive symptoms.

CONCLUSIONS

Our study provided first evidence that even light drinking in terms of the amount, frequency and type of alcohol beverages or light drinking patterns such as consuming 1-2 drinks less than monthly and half a drink monthly were associated with depressive symptoms in adolescents. Our results support total alcohol abstinence in adolescents.

Role of dietary factors in the prevention and treatment for depression: an umbrella review of meta-analyses of prospective studies

The role of diet in depression is becoming increasingly acknowledged. This umbrella review aimed to summarize comprehensively the current evidence reporting the effects of dietary factors on the prevention and treatment of depression. PubMed, Embase, and the Cochrane Library were searched up to June 2021 to identify relevant meta-analyses of prospective studies. Twenty-eight meta-analyses, with 40 summary estimates on dietary patterns (n = 8), food and beverages (n = 19), and nutrients (n = 13) were eligible. The methodological quality of most meta-analyses was low (50.0%) or very low (25.0%). Quality of evidence was moderate for inverse associations for depression incidence with healthy diet [risk ratio (RR): 0.74, 95% confidential interval (CI), 0.48-0.99, I2 = 89.8%], fish (RR: 0.88, 95% CI, 0.79-0.97, I2 = 0.0%), coffee (RR: 0.89, 95% CI, 0.84-0.94, I2 = 32.9%), dietary zinc (RR: 0.66, 95% CI 0.50-0.82, I2 = 13.9%), light to moderate alcohol (<40 g/day, RR: 0.77, 95% CI, 0.74-0.83, I2 = 20.5%), as well as for positive association with sugar-sweetened beverages (RR: 1.05, 95% CI, 1.01-1.09, I2 = 0.0%). For depression treatment, moderate-quality evidence was identified for the effects of probiotic [standardized mean difference (SMD): -0.31, 95% CI, -0.56 to -0.07, I2 = 48.2%], omega-3 polyunsaturated fatty acid (SMD: -0.28, 95% CI, -0.47 to -0.09, I2 = 75.0%) and acetyl-L-carnitine (SMD: -1.10, 95% CI, -1.65 to -0.56, I2 = 86.0%) supplementations. Overall, the associations between dietary factors and depression had been extensively evaluated, but none of them were rated as high quality of evidence, suggesting further studies are likely to change the summary estimates. Thus, more well-designed research investigating more detailed dietary factors in association with depression is warranted.

Racial discrimination, depressive symptoms, ethnic-racial identity, and alcohol use among Black American college students

BACKGROUND

Racial discrimination is prevalent among Black Americans, and may increase risk for alcohol use and related problems. Understanding the mediating and moderating factors in the pathways linking racial discrimination to alcohol use outcomes is important for prevention and intervention efforts. We tested depressive symptoms as a mediator and ethnic-racial identity as a moderator in the relation between racial discrimination and alcohol use outcomes among Black American young adults.

METHODS

We used data from 2 independent samples of Black American young adults recruited from different regions in the United States. The first sample included 383 Black American young adults (Mage = 20.65, SD = 2.28; 81% female), and the second sample included 165 Black American young adults (Mage = 21.56, SD = 4.92; 75% female).

RESULTS

Racial discrimination was associated with alcohol consumption and problems indirectly via depressive symptoms across the 2 independent samples. Moderation was evident for one sample such that high private regard levels buffered the association between racial discrimination and alcohol consumption, whereas high public regard levels exacerbated the association between racial discrimination and depressive symptoms.

CONCLUSIONS

Racial discrimination experiences put Black American young adults at risk for alcohol use and related problems through increased depressive symptoms. Ethnic-racial identity may buffer or exacerbate these associations depending on the specific dimension. The findings imply the need to target depressive symptoms and alcohol use simultaneously to promote health and well-being among Black Americans.

Impulsivity Scale-12 and its utilization in alcohol use disorder

INTRODUCTION

One of the core symptoms of alcohol use disorder (AUD) is impulsivity. The recently published study on the Impulsivity Scale 12 (IS-12) offers a promising tool to use in clinics working with clients with AUD due to its simplicity. IS-12 includes subscales related tocognitive impulsivity and behavioral impulsivity, which are related to different aspects of AUD symptomatology. The aim of the study was to adapt IS-12 to polish and test its utility in a sample of patients diagnosed with AUD.

METHODS

Using a Confirmatory Factor Analysis, we compared the two-factor model of the Polish adaptation of the BIS-11 and the IS-12 on a sample of 615 patients diagnosed with AUD. Additionally, we explored the association between the IS-12's cognitive impulsivity and behavioral impulsivity subscales and depressive symptoms, AUD severity, and suicidal ideation using Structural Equation Modeling on a subsample of 450 patients with AUD.

RESULTS

The IS-12 demonstrated a better model fit and good reliability compared to the BIS-11. Moreover, cognitive impulsivity predicted suicidal ideation, but not AUD severity, while behavioral impulsivity predicted AUD severity, but not suicidal ideation. Both subscales of IS-12 predicted depressive symptoms.

CONCLUSION

Consistent with prior work, findings indicate that the second-order factor model of the BIS-11 had reliability issues and evidenced poor model fit. In contrast, the IS-12 demonstrated a satisfactory model fit and was predictive of clinical symptomatology. Thus, utilizing an easy tool, such as IS-12, might be beneficial for researchers and clinicians working with patients with AUD.

Using Mendelian randomization analysis to better understand the relationship between mental health and substance use: a systematic review

BACKGROUND

Poor mental health has consistently been associated with substance use (smoking, alcohol drinking, cannabis use, and consumption of caffeinated drinks). To properly inform public health policy it is crucial to understand the mechanisms underlying these associations, and most importantly, whether or not they are causal.

METHODS

In this pre-registered systematic review, we assessed the evidence for causal relationships between mental health and substance use from Mendelian randomization (MR) studies, following PRISMA. We rated the quality of included studies using a scoring system that incorporates important indices of quality, such as the quality of phenotype measurement, instrument strength, and use of sensitivity methods.

RESULTS

Sixty-three studies were included for qualitative synthesis. The final quality rating was '-' for 16 studies, '- +' for 37 studies, and '+'for 10 studies. There was robust evidence that higher educational attainment decreases smoking and that there is a bi-directional, increasing relationship between smoking and (symptoms of) mental disorders. Another robust finding was that higher educational attainment increases alcohol use frequency, but decreases binge-drinking and alcohol use problems, and that mental disorders causally lead to more alcohol drinking without evidence for the reverse.

CONCLUSIONS

The current MR literature increases our understanding of the relationship between mental health and substance use. Bi-directional causal relationships are indicated, especially for smoking, providing further incentive to strengthen public health efforts to decrease substance use. Future MR studies should make use of large(r) samples in combination with detailed phenotypes, a wide range of sensitivity methods, and triangulate with other research methods.

Combined healthy lifestyle and depressive symptoms: a meta-analysis of observational studies

BACKGROUND

To systematically summarize the association between combined lifestyle (at least three factors, including but not limited to smoking, drinking, physical activity, body mass index, diet) and depressive symptoms by a meta-analysis in general populations.

METHODS

Multiple electronic databases were searched for observational studies investigating combined lifestyle factors and depressive symptoms published before September 2020. Pooled risk estimates were calculated using random-effects models. Publication bias was conducted using the Egger's and Begg's tests.

RESULTS

A total of 12 studies with 185,899 participants were included. The pooled OR of depressive symptoms in meta-analysis of 7 cross-sectional studies was 0.53 (0.39, 0.72), I² = 83.6%, P for heterogeneity <0.001 and the pooled RR was 0.33 (0.12, 0.89), I² = 95.3%, P for heterogeneity <0.001 in meta-analysis of 5 cohort studies for people with the highest versus lowest score of heathy lifestyles. In sensitivity analyses, the heterogeneity was significantly reduced in cross-sectional studies (pooled OR = 0.74 [0.65, 0.85], I² = 21.7%, P for heterogeneity = 0.27) and cohort studies (pooled RR = 0.53 [0.38, 0.74], I² = 15.2%, P for heterogeneity = 0.32). The publication bias corrected by "trim-and-fill" analysis yielded unchanged results.

LIMITATIONS

Limitations included residual confounding in original studies, heterogeneity between studies, and potential publication bias in the analysis of cross-sectional studies.

CONCLUSION

The healthy lifestyle was associated with a reduced risk of depressive symptoms. Adherence to overall healthy lifestyles is essential for the primary prevention of depression in general populations.

Association between successful aging transitions and depressive symptoms among older Korean adults: findings from the Korean longitudinal study of aging (2006-2018)

Background

The importance of SA (Successful aging) has been emphasized in recent years, with focus shifting towards attaining healthier aging rather than longevity. However, the influence of SA and its changes on mental health such as depression remains a relatively unexplored area in gerontology. Therefore, we investigated the longitudinal association between changes in SA and depressive symptoms in Korean older adults.

Methods

This study comprised a longitudinal sample of older adults aged ≥ 45 years, drawn from the Korean Longitudinal Study of Aging (2006–2018). Changes in SA status was determined using the Rowe and Kahn model over two consecutive years. Using an adjusted generalized estimating equation model, we examined the association between changes in successful aging status, namely SA and NSA (Non-successful aging), and depressive symptoms.

Results

Compared to the SA→SA group, depressive symptom risk in the NSA→NSA and SA→NSA groups were higher in men [(OR, 1.16; 95 % CI, 1.13–1.18), (OR, 1.11; 95 % CI, 1.08–1.13), respectively] and in women [(OR, 1.15; 95 % CI, 1.13–1.18), (OR, 1.11; 95 % CI, 1.09–1.14), respectively]. Subgroup analysis of the dimensions of successful aging revealed that low or worsening criteria of successful aging status in men and women were associated with depressive symptoms.

Conclusions

Korean older adults who continuously failed to attain or maintain successful aging status had the highest risk of depressive symptoms. These results could further assist in establishing policies and interventions that promote successful aging and subsequently protect the mental health of the Korean older adult population.

Prevalence of depression disorder in industrial workers: a meta-analysis

Objectives. Depression is known to be associated with a variety of occupational factors. The aim of this study was to meta-analyze the prevalence of depressive disorder in industrial workers. Methods. Three databases indexing abstracts of articles were selected and searched until August 2020: PubMed, Web of Science and Scopus. For each study, the sample size and number of depression events were extracted, and after extracting these data, the random effects method was used to assess the prevalence. I² and χ² values were used to investigate the heterogeneity. Results. The prevalence of depressive disorder in industrial workers is 21%. The prevalence of depressive disorder in men and women industrial workers is 23 and 28%, respectively. The prevalence of depressive disorder in Asia, Europe and America is equal to 22, 18 and 20%, respectively. The result of the heterogeneity test showed that the heterogeneity is high. Conclusion. The prevalence of depression in industrial workers is higher than in the general population. These differences can be due to the working conditions of industrial workers. Therefore, the work environment and the promotion of occupational health can play an important role in preventing depression.

Factors contributing to psychological distress in the working population, with a special reference to gender difference

Background

Psychological distress refers to non-specific symptoms of stress, anxiety and depression, and it is more common in women. Our aim was to investigate factors contributing to psychological distress in the working population, with a special reference to gender differences.

Methods

We used questionnaire data from the nationally representative Finnish Regional Health and Well-being Study (ATH) collected in the years 2012–2016 (target population participants aged 20 +, n = 96,668, response rate 53%), restricting the current analysis to those persons who were working full-time and under 65 of age (n = 34,468). Psychological distress was assessed using the Mental Health Inventory-5 (MHI-5) (cut-off value <=52). We studied the following factors potentially associated with psychological distress: sociodemographic factors, living alone, having children under18 years of age, lifestyle-related factors, social support, helping others outside of the home and work-related factors. We used logistic regression analysis to examine association between having work-family conflict with the likelihood for psychological distress. We first performed the models separately for men and women. Then interaction by gender was tested in the combined data for those independent variables where gender differences appeared probable in the analyses conducted separately for men and women.

Results

Women reported more psychological distress than men (11.0% vs. 8.8%, respectively, p < 0.0001). Loneliness, job dissatisfaction and family-work conflict were associated with the largest risk of psychological distress. Having children, active participation, being able to successfully combine work and family roles, and social support were found to be protective factors. A significant interaction with gender was found in only two variables: ignoring family due to being absorbed in one’s work was associated with distress in women (OR 1.30 (95% CI 1.00–1.70), and mental strain of work in men (OR 2.71 (95% CI 1.66–4.41).

Conclusions

Satisfying work, family life and being able to successfully combine the two are important sources of psychological well-being for both genders in the working population.

Association between Alcohol Drinking Status and Depressive Symptoms in Korean Adults

We investigated the association between alcohol drinking status and depressive symptoms in a representative sample of South Korean adults using data from the 2017 Korea Community Health Survey (KCHS), which included 216,771 participants (99,845 men and 116,926 women). Depression was defined as a Patient Health Questionnaire-9 score of ≥10. Multivariate logistic regression using sampling weights was used to assess the relationship between alcohol drinking status and depression after adjusting for potential confounders. Alcohol intake was nonlinearly associated with depression; the risk of depression was the lowest in men who were moderate drinkers and women who were light drinkers. In men, heavy drinkers (odds ratio [OR] 1.41, 95% confidence interval [CI] 1.19–1.67), light drinkers (OR 1.13, 95% CI 0.94–1.36), infrequent drinkers (OR 1.31, 95% CI 1.00–1.73), and lifetime abstainers (OR 1.38, 95% CI 1.09–1.75) were at a higher risk of depression than moderate drinkers. In women, moderate drinkers (OR 1.19, 95% CI 1.02–1.40) and heavy drinkers (OR 1.56, 95% CI 1.33–1.84) were at a higher risk of depression than light drinkers; however, infrequent drinkers and lifetime abstainers were not at a high risk of depression. In both men and women, former drinkers were at a higher risk of depression (OR 1.61, 95% CI 1.34–1.93 and OR 1.25, 95% CI 1.09–1.43, respectively). In conclusion, the association between alcohol drinking status and depression was nonlinear in both sexes. Further investigation of age- and sex-specific factors related to the association between alcohol use and depression is needed.

Selective serotonin reuptake inhibitors use and hepatocellular carcinoma in patients with alcohol use disorder

BACKGROUND

Research has proposed that selective serotonin reuptake inhibitors (SSRIs) were associated with a reduction of the risk of hepatocellular carcinoma (HCC). The objective of this study is to investigate whether SSRIs use is associated with decreased risk of HCC in patients with alcohol use disorder (AUD).

PATIENTS AND METHODS

We conducted a retrospective population-based cohort study using Taiwan's National Health Insurance Research Database (NHIRD) from 1997 to 2013 and enrolled patients with newly diagnosed AUD. After propensity scores matching at a ratio 1:4, total of 4945 SSRI users and 19,785 non-SSRI users were included in the matched cohort. Patients were followed up from the 365th day after the date of first exposure to SSRIs to occurrence of HCC, the date of death, or the end of 2013. Cox proportional hazard regressions were performed to evaluate hazard ratio (HRs) for HCC in SSRI-exposed patients compared with unexposed patients.

RESULTS

In the main study cohort, SSRI use was associated with significant lower risk of HCC compared to the non-SSRI users after adjusting for age, sex, income, urbanization, alcoholic fatty liver, alcoholic hepatitis and diabetes (adjusted hazard ratio [aHR] = 0.31, 95 % CI = 0.24-0.39). The negative association of SSRI use and HCC was replicated in the matched cohort (aHR = 0.58, 95 % CI = 0.44-0.77). The effect of SSRI use on HCC was dose-related in both cohorts (p for trend < 0.0001).

CONCLUSIONS

This study showed that SSRIs use was associated with a reduction risk of HCC among AUD patients in a cumulative dose effect manner.

Should fertile women quit drinking alcohol to produce better quality oocytes?

Alcohol consumption has long been shown to affect both fetal health and pregnancy. In this study, antral follicle count, maturation level of oocytes including morphological assessment and number of metaphase I (MI), metaphase II (MII) and germinal vesicle (GV) stage oocytes obtained from young women (age < 30 years old) with or without alcohol consumption were investigated. In total, 20 healthy women who were social drinkers and 36 healthy women who do not consume alcohol were involved in this study. Women in both study and control groups were undergoing controlled ovarian stimulation. The antral follicle count and the number and quality of the oocytes retrieved were evaluated and recorded. In total, 635 antral follicles, 1098 follicles and 1014 oocytes with 820 MII, 72 MI and 78 GV stage oocytes were collected from the social drinkers. In the control group, 628 antral follicles, 1136 follicles and 1085 oocytes with 838 MII, 93 MI and 102 GV stage oocytes were evaluated. The results of this study showed that the antral follicle count was very similar in both groups. The number of oocytes and MII stage oocytes was slightly higher in the control group, although it was not a significant difference. This study showed that although the consumption of alcohol may have adverse effects post-implantation, it may not have a solid effect during oogenesis in young women. The results of this study are especially important in clinical settings as some women who are social drinkers undergo in vitro fertilization treatments.

Explaining the rise and fall of psychological distress during the COVID-19 crisis in the United States: Longitudinal evidence from the Understanding America Study

OBJECTIVES

It has been shown that psychological distress rose rapidly as the COVID-19 pandemic emerged and then recovered to pre-crisis levels as social lockdown restrictions were eased in the United States. The aim of the current study was to investigate psychosocial and behavioural factors that may explain the rise and fall of distress during the initial months of the COVID-19 crisis.

DESIGN

This study examined six waves of longitudinal nationally representative data from the Understanding America Study (UAS) collected between March and June 2020 (N = 7,138, observations = 34,125).

METHODS

Mediation analysis was used to identify whether changes in distress (PHQ-4) during the COVID-19 pandemic were explained by the following factors: perceived infection risk and risk of death, perceived financial risks, lifestyle changes resulting from the virus, perceived discrimination related to the virus, and changes in substance use and employment status.

RESULTS

All mediating factors played a role in explaining changes in distress and together accounted for 70% of the increase in distress between 10-18 March and 1-14 April and 46.4% of the decline in distress between 1-14 April and early June 2020. Changes in perceived health risks were most important in explaining changes in distress followed by changes in lifestyle and the perceived financial risks associated with COVID-19.

CONCLUSIONS

This study provides longitudinal population-based evidence detailing the mediating factors explaining changes in distress during the COVID-19 crisis. Perceived health risks associated with the virus may play a key role in explaining rising and falling levels of psychological distress during the COVID-19 pandemic.

Bioinformatics identification and pharmacological validation of Kcnn3/KCa2 channels as a mediator of negative affective behaviors and excessive alcohol drinking in mice

Mood disorders are often comorbid with alcohol use disorder (AUD) and play a considerable role in the development and maintenance of alcohol dependence and relapse. Because of this high comorbidity, it is necessary to determine shared and unique genetic factors driving heavy drinking and negative affective behaviors. In order to identify novel pharmacogenetic targets, a bioinformatics analysis was used to quantify the expression of amygdala K+ channel genes that covary with anxiety-related phenotypes in the well-phenotyped and fully sequenced family of BXD strains. We used a model of stress-induced escalation of drinking in alcohol-dependent mice to measure negative affective behaviors during abstinence. A pharmacological approach was used to validate the key bioinformatics findings in alcohol-dependent, stressed mice. Amygdalar expression of Kcnn3 correlated significantly with 40 anxiety-associated phenotypes. Further examination of Kcnn3 expression revealed a strong eigentrait for anxiety-like behaviors and negative correlations with binge-like and voluntary alcohol drinking. Mice treated with chronic intermittent alcohol exposure and repeated swim stress consumed more alcohol in their home cages and showed hypophagia on the novelty-suppressed feeding test during abstinence. Pharmacologically targeting Kcnn gene products with the KCa2 (SK) channel-positive modulator 1-EBIO decreased drinking and reduced feeding latency in alcohol-dependent, stressed mice. Collectively, these validation studies provide central nervous system links into the covariance of stress, negative affective behaviors, and AUD in the BXD strains. Further, the bioinformatics discovery tool is effective in identifying promising targets (i.e., KCa2 channels) for treating alcohol dependence exacerbated by comorbid mood disorders.

Efficacy of pharmacotherapeutics for patients comorbid with alcohol use disorders and depressive symptoms-A bayesian network meta-analysis

Background

We aimed to compare and rank the efficacy of different pharmacotherapeutics for patients comorbid with alcohol use disorders and depressive symptoms.

Method

Bayesian network meta‐analysis was performed for three different outcome parameters: alcohol use disorders (AUD) remission rate, percent abstinent days, and scores of depression scales. The surface under the cumulative ranking curves (SUCRA) was used for ranking the efficacy of interventions. Sensitivity analysis and direct pairwise analysis were conducted to validate the main results.

Results

A total of 68 RCTs consisting of 5890 patients were included. Disulfiram could significantly increase the AUD remission rates (OR 5.02, 1.97‐12.95) and the percent abstinent days (MD 17.08, 3.48‐30.93). Disulfiram was associated with the best efficacy in achieving remission (SUCRA 95.1%) and increasing abstinent days (SUCRA 87.6%). Noradrenaline reuptake inhibitor was significantly more efficacious than controls (SMD −2.44, −3.53 to −1.36) and have the first rank (SUCRA 99.0%) in reducing the scores of depression scales. Antiepileptics have relatively higher ranks in efficacy for both AUD and depressive symptoms.

Conclusions

Disulfiram was associated with the best efficacy in achieving abstinence for comorbidity patients. Noradrenaline reuptake inhibitor was demonstrated to be associated with the best efficacy in reducing scores of depression scales. Antiepileptics might be beneficial to both alcohol‐related and depressive symptoms.

Contribution of Alcohol and Nicotine Dependence to the Prevalence of Depressed Mood in Different Ethnic Groups in The Netherlands: The HELIUS Study

Objective: Ethnic minorities report different levels of drinking and smoking and higher rates of depression compared to native populations. In this study we aimed to investigate in six ethnic groups whether tobacco and alcohol use were associated with depressive symptoms, which are more prevalent in ethnic minorities.Methods: Cross-sectional data from the multi-ethnic Healthy Life in an Urban Setting (HELIUS) study sample (N = 22,471) was used, comprising 4,580 native Dutch participants which were compared with participants from five ethnic minority groups (3,259 South Asian Surinamese, 4,292 African Surinamese, 2,262 Ghanaian, 3,891 Turkish, and 4,187 Moroccan).Results: Alcohol misuse was positively associated with depressed mood in all ethnic groups except for the Dutch and the Ghanaians. Nicotine dependence was positively associated with depressed mood in all ethnic groups except for the Ghanaian group.Conclusions: Alcohol misuse and nicotine dependence were significantly associated with depressed mood in most but not all ethnic groups and especially in men. However, across all groups the contribution of alcohol misuse and nicotine dependence to depressed mood was small. Prospective multi-ethnic studies should confirm whether the relations are causal and elucidate their direction.
