An exploration of the dynamic longitudinal relationship between mental health and alcohol consumption: a prospective cohort study

Adding Nuance to Understanding the Effects of Cannabis Legalization by Using Policy Bundles: A Study of Youth Mental Health

BACKGROUND

Variation in policy design presents a challenge for understanding the positive and negative externalities of cannabis legalization. We offer an advancement on measuring state cannabis policy variation - policy bundles - and demonstrate how the measure can be used to test the effects of cannabis legalization on youth mental health.

METHODS

This research employs data from the Youth Risk Behavior Survey (YRBS), released by the Centers for Disease Control and Prevention (CDC). The research focuses on utilizing three policy bundles as main exposures. This study utilizes a logistic regression model to analyze the outcome exposures. Furthermore, we employ instrumental variables to solve endogeneity between cannabis use and mental health.

RESULTS

Both the pharmaceutical and permissive policy bundle scales are associated with mental health improvements, whereas greater fiscalization has a negative impact on mental health.

CONCLUSION

Studies of the positive and negative externalities of cannabis legalization must consider variation in policy design.

Diverging trends in alcohol-related harms: The role of comorbid mental health, suicide and self-harm behaviors in ambulance attendances for alcohol intoxication during the COVID-19 pandemic in Victoria, Australia

BACKGROUND

Alcohol harms changed significantly during COVID-19, but did not affect the population equally. Vulnerable groups including people with pre-existing mental health or suicidal behaviors may be at greater risk of alcohol-related harms, yet limited public health data are able to assess these.

METHODS

The present study utilised a novel, statewide surveillance system to examine ambulance attendances for alcohol intoxication over a four-year period prior to, and during the strictest lockdowns in Victoria, Australia.

RESULTS

While there was an overall reduction in alcohol-related attendances during lockdown (n = 15,064) compared to the 2018-19 period (n = 16,989), alcohol- intoxication attendances involving mental health symptoms increased by 40 % in Melbourne (IRR: 1.40 [1.30-1.51], p < 0.001), and by 25 % in regional Victoria (IRR: 1.25 [1.07-1.44], p = 0.005).There was also a 7 % increase in alcohol-intoxication attendances with co-morbid suicidal behaviors in Melbourne (IRR: 1.07 95%CI [1.02-1.13], p = 0.006), and a 21 % increase in regional Victoria (IRR: 1.21 [1.08-1.35], p = 0.001).

CONCLUSIONS

These findings suggest that extra services and supports for individuals with co-morbid alcohol-related harms are required to ensure their clinical care needs are being met.

Prevalence of hazardous alcohol consumption and evaluation of associated factors in university students

PURPOSE

The aim of the study was to determine the prevalence of hazardous alcohol consumption (HAC) according to gender among university students and associated factors.

METHODS

This is a cross-sectional study conducted on undergraduate students. We used a stratified sampling technique to represent 26036 students from all grade levels and 11 faculties, and the survey was administered to 2349 undergraduate students. The prevalence of HAC was determined with the Alcohol Use Disorders Identification Test (AUDIT). HAC was defined as getting 8 points or more from the AUDIT. Multivariate logistic regression analyses were performed to examine HAC related factors in both genders.

RESULTS

In this study, 53.2% of the participants were male. The prevalence of HAC in the study group was 13.5% and prevalence of lifetime drinker was 65.3%. In males; those whose fathers [OR = 1.72; 95% CI: (1.17-2.52)], mothers [1.49; (1.02-2.18)], close friends [2.42; (1.28-4.60)] drink alcohol and smoking [3.16; (2.09- 4.77)], use illicit substance [2.35; (1.66-3.34)], have mental health problems [1.65; (1.04-2.62)] were more likely to report HAC. Meanwhile in females, those whose fathers [OR = 1.92; 95%CI: (1.03-3.57)], close friends [5.81; (1.73-19.45)] drink alcohol and smoking [4.33; (2.31-8.15)], use illicit substance [4.34; (2.34-8.06)] have mental health problems [3.01; (1.67-5.43)] were more likely to report HAC.

CONCLUSIONS

HAC prevalence is high among university students. The risk of HAC increases with the use of alcohol in family and circle of friends, smoking, illicit substance use and mental health problems. The factors associated with the risk of HAC in both genders are similar.

The non-linear correlation between the severity of alcohol consumption and depressive symptoms in the Chinese Wa ethnic minority

Objective

The aim of this research was to examine the association between alcohol consumption and depressive symptoms in the Wa ethnic minority of China, a population where this relationship has been insufficiently explored.

Methods

A cross-sectional analysis was conducted on a sample of 317 current drinkers from the Wa ethnic minority, a "direct fast-forward" group in Cangyuan County, between December 1, 2022, and February 28, 2023. Utilizing a multi-stage cluster sampling approach, participants were selected, each of whom exhibited an Alcohol Use Disorder Identification Test (AUDIT) score exceeding 0. Data were collected via face-to-face interviews employing a uniform questionnaire. Quantification of alcohol use was achieved through the application of the AUDIT, while the Patient Health Questionnaire (PHQ)-9 was employed to gauge depressive symptoms. The relationship between the severity of alcohol consumption and depressive symptoms was evaluated using a multivariable logistic regression model. Subsequently, potential non-linear associations were scrutinized through the application of a smoothing plot.

Results

The study included 317 current drinkers (196 males [61.83%]; mean age 41.78 ± 12.91 years), of which 94 (29.65%) exhibited comorbid depressive symptoms. Multivariable logistic regression analysis, adjusting for confounders, revealed that higher AUDIT scores were significantly associated with an increased probability of depressive symptoms (OR = 1.09, 95% CI: 1.02-1.18, p = 0.008). The risk of depressive symptoms was notably greater in the group with alcohol dependent range in contrast the group at low-risk range (OR = 7.01, 95% CI: 1.66-29.62, p = 0.008). The smoothing plot indicated a J-shaped non-linear relationship with an inflection point at an AUDIT score of 15. To the left of this inflection point, no significant relationship was observed, whereas to the right, a positive correlation emerged (OR = 1.39, 95% CI: 1.11-1.74, p < 0.001).

Conclusion

The findings reveal a non-linear relationship between alcohol consumption and the probability of depressive symptoms within the Wa ethnic minority in China, with implications for the development of nuanced and effective treatment strategies tailored to this population.

Drinking and mental health in middle adulthood: exploring the impact of wellbeing, mental health literacy, and drinking motives on risk of alcohol dependence

OBJECTIVES

Risky drinking is a concern among UK-based middle-aged adults. We aimed to explore the relationship between risky drinking, drinking motives, wellbeing, and mental health literacy (MHL).

METHOD

Cross-sectional analysis of online survey data completed by 193 UK-based adults aged 40-65 who drank alcohol, incorporating the Alcohol Use Disorders Identification Test (AUDIT); Drinking Motives Questionnaire-Revised (DMQ-R); Warwick-Edinburgh Mental Wellbeing Scale (WEMWBS); Mental Health Literacy Scale (MHLS) and demographic questions.

RESULTS

Coping, enhancement and conformity motives and gender significantly predicted higher AUDIT scores (measuring risky drinking). Enhancement motives were found to mediate the relationship between the self-help component of MHL and AUDIT scores, while coping motives mediated the association between wellbeing and AUDIT scores.

CONCLUSION

Findings support research emphasising the influence of drinking motives on risky drinking and highlights how low wellbeing may interact with coping motives to explain risky drinking among middle-aged adults, particularly men. Interventions supporting individuals to understand the relationship between drinking motives and risky drinking, develop adaptive coping strategies, and address the causes of low wellbeing, may be beneficial. However, as the sample was 84% ethnically White, 64% women, 85% educated to at least undergraduate level, and reported a relatively high mean socioeconomic status (6.98 out of 10), the results may not generalise beyond these groups. Future research should use stratified sampling to increase generalisability, as well as exploring whether alcohol-specific, component-specific, or disorder-specific MHL is associated with risky drinking and wellbeing.

Emotional and cognitive influences on alcohol consumption in middle-aged and elderly Tanzanians: a population-based study

Alcohol consumption in Tanzania exceeds the global average. While sociodemographic difference in alcohol consumption in Tanzania have been studied, the relationship between psycho-cognitive phenomena and alcohol consumption has garnered little attention. Our study examines how depressive symptoms and cognitive performance affect alcohol consumption, considering sociodemographic variations. We interviewed 2299 Tanzanian adults, with an average age of 53 years, to assess their alcohol consumption, depressive symptoms, cognitive performance, and sociodemographic characteristics using a zero-inflated negative binomial regression model. The logistic portion of our model revealed that the likelihood alcohol consumption increased by 8.4% (95% confidence interval [CI] 3.6%, 13.1%, p < 0.001) as depressive symptom severity increased. Conversely, the count portion of the model indicated that with each one-unit increase in the severity of depressive symptoms, the estimated number of drinks decreased by 2.3% (95% CI [0.4%, 4.0%], p = .016). Additionally, the number of drinks consumed decreased by 4.7% (95% CI [1.2%, 8.1%], p = .010) for each increased cognitive score. Men exhibited higher alcohol consumption than women, and Christians tended to consume more than Muslims. These findings suggest that middle-aged and elderly adults in Tanzania tend to consume alcohol when they feel depressed but moderate their drinking habits by leveraging their cognitive abilities.

Impacts of alcohol consumption on farmers' mental health: Insights from rural China

The global mental health crisis presents a significant challenge to sustainable development, and this crisis is more pronounced in China's rural areas versus urban areas. Alcohol consumption has increased in rural areas with China's economic growth, but the number of studies on the relationship between farmers' alcohol consumption and their mental health is limited. Based on data from the China Labor Force Dynamics Survey (CLDS), this study uses the endogenous switching regression model (ESR) to analyze the influence of alcohol consumption on farmers' mental health. On this basis, the study further conducts a counterfactual analysis to estimate the average treatment effect of alcohol consumption on farmers' mental health. The results show that: (1) There is a significant positive relationship between alcohol consumption and farmers' mental health. Specifically, the mental health index of drinking farmers increases by 19.7 % compared to non-drinking farmers. (2) Heterogeneity analysis shows that alcohol consumption is more beneficial for improving the mental health of male farmers, elderly farmers, and employed farmers. Furthermore, drinking alcohol almost every day, consuming Baijiu, and each drinking consumption ranging from 0 to 100 mL per occasion are more conducive to improving farmers' mental health. These findings have implications for relieving depressive symptomology and improving farmers' mental health in developing countries. The results of this study also provide guidance for addressing the global mental health crisis.

Risky Alcohol Use and Romantic Relationships Among College Students: A Longitudinal Study

BACKGROUND

Risky alcohol use is frequent among college students and can be associated with functional outcomes. Bidirectional associations have been shown between alcohol use and the stability of romantic relationships, though little is known about the longitudinal association between risky alcohol use and romantic relationships in college and about college students' perceived stress regarding one's love life. Objectives: The present study aims to explore these relationships both cross-sectionally and at one-year follow-up.

METHOD

Data were drawn, from the French portion of the World Mental Health International College Student Survey initiative (WMH-ICS). First-year college students who completed an online survey (n = 1,624) and a second survey at one-year follow-up (n = 727) were included. Current romantic relationship status and stress regarding one's love life, past-year risky alcohol use, lifetime presence of DSM-5 mental health disorders and sociodemographic correlates were assessed.

RESULTS

Risky alcohol use was cross-sectionally associated with dating in multivariate models adjusting for lifetime mental disorders (aOR = 1.70, 95%CI = 1.31-2.20), and in particular with unsteady relationships (aOR = 2.87, 95%CI = 2.01-4.10), but was no longer associated with both one year later. Risky alcohol use was, however, not associated with severe perceived stress regarding one's love life in multivariate models adjusting for lifetime mental disorders in both cross-sectional and longitudinal analyses, while it was associated in bivariate models for both analyses.

CONCLUSIONS

These findings extend our understanding of the association between excessive drinking and romantic relationship patterns among college students underlying the importance of comorbid disorders.

Mental health is positively associated with biodiversity in Canadian cities

Cities concentrate problems that affect human well-being and biodiversity. Exploring the link between mental health and biodiversity can inform more holistic public health and urban planning. Here we examined associations between bird and tree species diversity estimates from eBird community science datasets and national forest inventories with self-rated mental health metrics from the Canadian Community Health Survey. We linked data across 36 Canadian Metropolitan Areas from 2007-2022 at a postal code level. After controlling for covariates, we found that bird and tree species diversity were significantly positively related to good self-reported mental health. Living in a postal code with bird diversity one standard deviation higher than the mean increased reporting of good mental health by 6.64%. Postal codes with tree species richness one standard deviation more than the mean increased reporting of good mental health by 5.36%. Our results suggest that supporting healthy urban ecosystems may also benefit human well-being.

Exploring experiences with alcohol and how drinking has changed over time among minority ethnic groups with a diagnosed mental health problem

INTRODUCTION

Minority ethnic groups are more likely to experience poor mental health but less likely to seek formal support. Mental health problems and alcohol use (including non-drinking) co-occur, the reasons for this among minority ethnic groups are not well understood. This study explored i) alcohol use among minority ethnic individuals with a mental health problem,ii) how alcohol was used before individuals received support for their mental health,iii) how alcohol changed whilst and after individuals received treatment for their mental health.

METHODS

Participants were purposively sampled through community/online mental health organisations. Participants took part if they i)were not White British, ii) had a mental health diagnosis, iii) drank at hazardous and above levels or former drinkers. Telephone/online semi-structured interviews were conducted. Data were analysed using framework analysis with an intersectional lens.

RESULTS

25 participants took part. Four themes were developed; "drinking motivations", "mental health literacy and implications on drinking behaviour", "cultural expectations and its influence on mental health problems and drinking practices", and "reasons for changes in drinking". Themes reflect reasons for drinking and the role of understanding the range of mental health problems and implicit cultural expectations. An intersectional lens indicated gendered, ethnic and religious nuances in experiences with alcohol and seeking support. Engaging with formal support prompted changes in drinking which were facilitated through wider support.

CONCLUSION

There were specific reasons to cope among minority ethnic individuals who have a mental health problem. Applying an intersectional lens provided an insight into the role of cultural and gendered expectations on mental health and drinking practices. Mental health literacy and implicit cultural expectations within specific minority ethnic groups can affect both mental health and drinking practices. Healthcare professionals and wider community play an important role in prompting changes in drinking among minority ethnic groups who have a mental health problem.

Examining the association between psychological distress and alcohol use in Australian adolescents over a period of declining consumption

INTRODUCTION

Youth drinking rates have declined over the past 15 years while self-reported psychological distress has increased, despite a well-recognised positive relationship between the two. The current study aimed to identify changes in the relationship between psychological distress and alcohol use in adolescents from 2007 to 2019.

METHODS

This study used survey responses from 6543 Australians aged 14-19 years who completed the National Drug Strategy Household Survey in 2007, 2010, 2013, 2016 or 2019. Logistic and multivariable linear regressions with interactions (psychological distress × survey wave) predicted any alcohol consumption, short-term risk and average quantity of standard drinks consumed per day.

RESULTS

Psychological distress was a positive predictor of alcohol use and this association remained stable across survey waves as alcohol consumption decreased.

DISCUSSION AND CONCLUSIONS

The relationship between distress and alcohol consumption remained relatively steady, even as youth drinking declined and distress increased. The proportion of drinkers experiencing distress did not increase as consumption rates dropped, suggesting that the decline in youth drinking is occurring independently of the increase in self-reported and diagnosed mental health issues.

Physical activity and specific symptoms of depression: A pooled analysis of six cohort studies

BACKGROUND

The association between physical activity (PA) and depression is well-established, but the details that explain this association remain elusive. We examined whether PA is differentially associated with specific symptoms of depression (e.g., cognitive vs somatic symptoms), and whether these associations follow a dose-response pattern with respect to intensity or frequency of PA.

METHODS

Cross-sectional analyses were based on 6 samples of the continuous U.S. National Health and Nutrition Examination Surveys (NHANES) carried out between 2007 and 2018 (n = 28,520). Depressive symptoms were assessed with Patient Health Questionnaire 9 (PHQ-9). Information about PA (vigorous, moderate, and daily commuting by foot or bike) and covariates was self-reported.

RESULTS

After adjusting for education, health behaviors, body-mass index, physical functioning, and all the other depressive symptoms, lower PA was specifically associated with four depressive symptoms: loss of interest/pleasure, feeling down/hopeless, fatigue, and changes in appetite (odds ratios from 0.94 to 0.59). A monotonic dose-response pattern on PA amount was observed only for interest/pleasure and fatigue, and these associations were independent of PA intensity.

LIMITATIONS

Cross-sectional data did not allow us to assess temporal ordering. Both depressive symptoms and PA were self-reported, which may induce bias.

CONCLUSION

Low PA may be linked to depressive symptoms particularly through the symptoms of anhedonia and fatigue. Given that their association with PA amount follows a dose-response pattern and is independent of PA intensity, we hypothesize that behavioral activation and exposure to rewarding experiences might help to explain why PA alleviates depression.

Understanding alcohol use and changes in drinking habits among people with a severe mental illness: a qualitative framework analysis study

Introduction

Individuals with a severe mental illness (SMI) are more likely to drink at harmful levels or abstain. While it is known that drinking patterns change over time, the reasons for this among those with a SMI are unclear. This study aimed to (i) explore the experiences with alcohol, particularly in relation to mental health symptoms, and (ii) how drinking patterns have changed over time, among individuals who have a SMI diagnosis, who either currently drink alcohol or no longer drink.

Methods

One-to-one semi-structured telephone interviews were conducted to address the study aims. Current drinkers' alcohol use was assessed using the Alcohol Use Disorder Identification Test. A framework analysis was used to address the study aims with a specific focus on the differences in the experiences with alcohol use between current and former drinkers.

Results

16 participants were interviewed, and five themes were developed. The analysis highlighted how alcohol was increasingly used to cope with (i) trauma, (ii) SMI-related symptoms, or (iii) stress. Among those with a SMI, non-drinking was facilitated through declines in SMI-related symptoms, previous negative consequences due to alcohol and changing the social environment. Current drinking habits were facilitated through changes in the reasons for drinking and adopting different alcohol moderation techniques.

Discussion

Among those with a SMI diagnosis and who either currently drink alcohol or no longer drink, our findings support the self-medication hypothesis and drinking motives model. However, our findings indicate the need for further development of drinking to cope with a focus on symptoms of a SMI and trauma. Our findings also have implications on specialist alcohol and mental health services, the need to improve individuals' understanding of SMI, and the need to identify reasons for drinking among those with a recent diagnosis of a SMI.

Gender differences in alcohol abuse/dependence among medical undergraduates during the post-COVID‑19 pandemic period (October 20, 2020-April 5, 2021) in China

BACKGROUND

This study aimed to assess the prevalence and the gender-specific risk factors of alcohol abuse/dependence among medical undergraduates during the post-COVID‑19 pandemic period in China.

METHOD

The Alcohol Use Disorders Identification Test-Consumption (AUDIT-C) was used to identify respondents with alcohol abuse/dependence. A questionnaire on basic demographics and mental distresses (learning burnout, depression symptoms, anxiety symptoms, excessive daytime sleepiness, and history of mental disorders) was used. The logistic regression model was used to explore the associations between the above characteristics and alcohol abuse/dependence.

RESULTS

A total of 3,412 medical undergraduates were included in the analysis. Males showed a higher prevalence of alcohol abuse/dependence than females (16.6% vs 7.4%, p < 0.001). Alcohol abuse/dependence was associated with learning burnout (OR: 2.168, p < 0.001) and having a partner (OR: 1.788 p = 0.001) among female medical undergraduates. Among male medical undergraduates, excessive daytime sleepiness (OR: 1.788 p = 0.001) and older age (OR: 1.788, p = 0.001) were independently associated with alcohol abuse/dependence.

CONCLUSION

Alcohol abuse/dependence was common among medical undergraduates during the post-COVID‑19 pandemic period. Substantial gender differences in the prevalence and risk factors of alcohol abuse/dependence were found among medical undergraduates in this study, which highlighted the need for timely gender-specific screening and interventions. However, the cross-sectional design adopted in this study has limited the examination of causality, thus further longitudinal studies are warranted.

Longitudinal patterns of alcohol use and psychological symptoms during COVID-19 pandemic and role of alexithymia: A latent transition analysis in the FinnBrain Birth Cohort Study

BACKGROUND

The COVID-19 pandemic has been posing widespread influence on mental well-being. However, research on the dynamic relations between alcohol use and psychological symptoms in the context of the pandemic and the role of alexithymic traits in predicting the development of mental health problems longitudinally remains scarce.

METHODS

Latent profile and transition analyses were conducted to model the longitudinal patterns of transitions in the profiles of alcohol use and psychological symptoms across 10 months during the pandemic (from May 2020 to March 2021) and to investigate the role of alexithymia and its dimensions Difficulty Identifying and Describing Feelings (DIF and DDF), and Externally Oriented Thinking (EOT) in 720 parents from the FinnBrain Birth Cohort Study.

RESULTS

Three profiles, Risky Drinking, Distressed Non-Risky Drinking, and Non-Distressed, Non-Risky Drinking, and their transitions were identified. The role of alexithymia appeared to be stronger in Risky Drinking than Non-Distressed, Non-Risky Drinking. DIF predicted the development of symptoms in Risky Drinking, whereas DDF predicted Risky Drinking remaining stable over time and showed a trend towards psychological distress in Risky Drinking and Non-Distressed, Non-Risky Drinking. EOT was more likely to be a risk factor for Risky Drinking remaining constant and Non-Distressed, Non-Risky Drinking becoming Risky Drinking.

LIMITATIONS

This study was mainly limited by the generalizability of the findings.

CONCLUSIONS

Our findings add deeper insights into the longitudinal development of alcohol use and psychological symptoms as well as evidence on the role of alexithymia in shaping mental health, providing implications for tailoring clinical preventive and therapeutic measures.

Is the association between psychological distress and risky alcohol consumption shifting over time? An age-period-cohort analysis of the Australian population

This study explored age, period, and cohort effects associated with trends in psychological distress and risky alcohol consumption. Data came from 108,536 Australians aged 14-79 years old from birth cohorts between 1925-2005, endorsing past year alcohol use in the 2004-2019 Australian National Drug Strategy Household Surveys. Risky alcohol consumption was split into exceeding weekly national drinking limits (>10 drinks per week) or daily limits (>4 drinks per day). An extended hierarchical age-period-cohort model was used to investigate differential effects on trends in psychological distress. Psychological distress showed an inverse U-shape throughout the lifespan with a peak in distress at age 60. Exceeding weekly alcohol limits was positively related to psychological distress prior to age 40 while exceeding daily alcohol limits remained positively related across the lifespan. There were relatively flat period effects, with no alcohol-related changes in psychological distress across years. Lastly, psychological distress gradually increased across birth cohorts until a notable spike among Australians born from 1980-2005 alongside weakening alcohol-related cohort effects. Overall, the recent increases in psychological distress did not appear to be meaningfully explained by risky alcohol consumption though risky alcohol consumption remained an important factor to consider alongside psychological distress.

Association of alcohol consumption and fatigue in SLE: A cross-sectional study from Lupus Registry of Nationwide Institution (LUNA) cohort

OBJECTIVE

Fatigue is one of the most common complaints and is a potentially modifiable issue in systemic lupus erythematosus (SLE). Studies suggest that alcohol consumption has a protective effect against the development of SLE; however, an association between alcohol consumption and fatigue in patients with SLE has not been studied. Here, we assessed whether alcohol consumption was associated with fatigue using lupus patient-reported outcomes (LupusPRO).

METHODS

This cross-sectional study, conducted between 2018 and 2019, included 534 patients (median age, 45 years; 87.3% female) from 10 institutions in Japan. The main exposure was alcohol consumption, which was defined as the frequency of drinking [<1 day/month (none group), ≤1 day/week (moderate group), and ≥2 days/week (frequent group)]. The outcome measure was the Pain Vitality domain score in LupusPRO. Multiple regression analysis was performed as the primary analysis after adjusting for confounding factors, such as age, sex, and damage. Subsequently, the same analysis was performed as a sensitivity analysis after multiple imputations (MIs) for missing data (n = 580).

RESULTS

In total, 326 (61.0%) patients were categorized into the none group, 121 (22.7%) into the moderate group, and 87 (16.3%) into the frequent group. The frequent group was independently associated with less fatigue compared with none group [β = 5.98 (95% CI 0.19-11.76), p = 0.04], and the results did not substantially deviate after MI.

CONCLUSIONS

Frequent drinking was associated with less fatigue, which highlights the need for further longitudinal studies focusing on drinking habits in patients with SLE.

Mental health problems and admissions to hospital for accidents and injuries in the UK military: A data linkage study

PURPOSE

Accidents are the most common cause of death among UK military personnel. It is a common misconception in the general public that accidental injuries are always the result of random events, however research suggests that mental health problems and the increased levels of risky behaviour in military personnel may play a role. The objective of this study was to further our understanding of injuries and deaths not related to deployment by examining the associations of mental health, alcohol misuse and smoking with inpatient admission to hospital for accidents and injuries, and attendance to accident and emergency (A&E) departments.

METHODS

Data on all hospital admissions for accidents and injuries and A&E attendance at NHS hospitals in England, Scotland and Wales were linked to data on self-reported mental health problems, alcohol misuse and smoking from a large, representative UK military cohort of serving and ex-serving personnel (n = 8,602). Logistic regression was used to examine the associations between having a hospital admission for an accident or injury with self-reported mental health problems, alcohol misuse and smoking. Cox proportional-hazards regression was then conducted to assess the associations of mental health problems, alcohol misuse and smoking with time to hospital admission for an accident or injury. Finally, negative binomial regression was used to examine associations between the number of A&E attendances with mental health problems, alcohol misuse and smoking.

RESULTS

Personnel reporting symptoms of common mental disorder (CMD) or probable post-traumatic stress disorder (PTSD) were more likely to have an admission to hospital for an accident or injury (fully adjusted odds ratio 1.39, 95% confidence interval [CI] 1.05-1.84), than those who did not report these symptoms, and also had more attendances to A&E (fully adjusted incidence rate ratio [IRR] 1.32, 95% CI 1.16-1.51). A&E attendances were also more common in personnel who were smokers (fully adjusted IRR 1.21, 95% CI 1.09-1.35) following adjustment for demographic, military and health characteristics.

CONCLUSIONS

The findings suggest that accidents and injuries among military personnel are not always random events and that there are health and behavioural factors, including poor mental health and smoking, which are associated (with small effect sizes) with an increased risk of being involved in an accident. Clinicians treating individuals attending hospital after an accident should consider their healthcare needs holistically, including issues related to mental health and health damaging behaviours.

Characteristics of people who have received treatment for late-onset problem drinking and alcohol use disorder: A systematic review and narrative synthesis

Aims: The current review investigated the psychosocial characteristics of late-onset problem drinkers, an under-researched area of alcohol harm that accounts for one-third of older problem drinkers. Method: Following the PRISMA model, the protocol and search strategy included a scoping search and main search of nine databases. A total of 1,595 papers were identified; after screening, 26 papers were considered eligible and were included in the review. The review used an investigative framework comprising three categories: standardising age of onset; gender differences; and psychosocial and mental health characteristics. The review also investigated how meaning and purpose in life, and treatment have been reported in relation to this cohort. Findings/Conclusions: The combined onset ages of the reviews’ 26 papers (mean age = 52.69 years) and the participants’ self-reported age at onset (mean age = 56.79 years), suggest that late-onset alcohol use disorder (AUD)/problem drinking is likely to emerge at the age of 55 years and older. Moreover, there is a high prevalence of co-morbid mental health disorders among elderly, late-onset drinkers. Retirement was reported as the most prevalent psychosocial risk factor for late-onset problematic drinking; other late-life events included bereavement, loneliness and social isolation, and boredom. In the context of gender, women are at greater risk of developing late-onset problem drinking than men. Furthermore, late-onset problem drinkers, particularly women, are more treatment compliant than their early-onset counterparts, highlighting the case for bespoke treatments/interventions for late-onset problem drinkers. Finally, the role that meaning and purpose in life plays in late-onset problem drinking has been under-reported and requires further investigation.

Gender-specific characteristics of alcohol use in community-dwelling older adults in Belgium

OBJECTIVES

Gender has been identified as an important social determinant for health. This study investigates gender-specific characteristics for alcohol use (AU) among community-dwelling older adults.

METHODS

This is a retrospective cross-sectional study in 1.406 community-dwelling older adults. We used standardized questionnaires to collect self-reported data on alcohol use behavior, mental health, drinking motives and resilience by using, respectively, the Alcohol Use Identification Test (AUDIT), the Brief Symptom Inventory (BSI), the Drinking Motives Questionnaire (DMQ), and the Connor-Davidson Resilience Scale (CD-RISC). Multiple linear regression was used to identify the joint contribution of those factors on AU. Hierarchical regression was used to investigate the influence of the interaction between gender and those factors on AU.

RESULTS

Linear regression analyses showed different associations with AU in men and women. Hierarchical regression analyses showed that gender presented a two-way interaction effect with enhancement and anxiety variables related to AU.

CONCLUSIONS

Different characteristics were found as predictors for AU among older men and women.

CLINICAL IMPLICATIONS

Clinicians and health-care providers should be aware of these differences in order to provide tailored screening and intervention programs to reduce AU in older adults.

Flourishing mental health and lifestyle behaviours in adults with Type 1 and Type 2 Diabetes Mellitus: results from the Diabetes MILES - The Netherlands Study

OBJECTIVE

To examine the associations between mental health and lifestyle in adults with type 1 and type 2 diabetes mellitus (T1DM and T2DM).

METHODS

Online survey data from the cross-sectional Diabetes MILES - The Netherlands Study was analysed, including 270 adults with T1DM and 325 with T2DM. Mental health status (flourishing, moderate and languishing) in relation to diet, physical activity, alcohol consumption and smoking was analysed with ANCOVA and logistic regressions (adjusted for confounders).

RESULTS

47% of T1DM-, and 55% of T2DM participants reported flourishing mental health. Due to an insufficient number, participants with languishing mental health were excluded. In T2DM, participants with flourishing mental health had more optimal diet quality (mean ± SEM: 70 ± 1 vs 68 ± 1 diet quality score, p = 0.015), and physical activity levels (mean ± SEM: 3484 ± 269 vs 2404 ± 273 MET minutes/week, p = 0.001) than those with moderate mental health, but did not differ with respect to alcohol consumption and smoking. In T1DM, no significant associations were found.

CONCLUSION

Only in T2DM, people with flourishing mental health had more optimal lifestyle behaviours compared to people with moderate mental health. Further research is needed to determine if mental health is more important for specific lifestyle behaviours, and if the mental health effect differs across diabetes types.

Do symptoms of depression and anxiety contribute to heavy episodic drinking? A 3-wave longitudinal study of adult community members

Heavy episodic drinking (or binge drinking) is a significant public health concern. Self-medication using alcohol is often thought to explain the co-occurrence of heavy episodic drinking with depression and anxiety. Yet, there is little longitudinal work examining both depressive and anxiety symptoms and how they are independently related to heavy episodic drinking in adult community samples. To this end, we invited adult community members (N = 102) to come to the lab to complete validated measures of depressive symptoms (composite of CES-D-SF, SCL-90-D, and DASS-21-D), anxiety symptoms (DASS-21-A), and heavy episodic drinking (composite of frequency, severity, and perceptions) at baseline, and again three and six months later. Using a three-wave cross-lagged panel model, we tested reciprocal relations between heavy episodic drinking and each internalizing symptom. We found strong temporal stability in our study variables. Depressive symptoms were associated with increases in heavy episodic drinking, and anxiety symptoms were associated with decreases in heavy episodic drinking. In contrast, heavy episodic drinking did not predict either internalizing symptom over time. Results are consistent with the notion that individuals with greater depressive symptoms use alcohol to self-medicate, and that anxiety symptoms (particularly autonomic arousal) may be potentially protective against future heavy episodic drinking.

Associations of common mental disorder with alcohol use in the adult general population: a systematic review and meta-analysis

BACKGROUND AND AIMS

Research has shown that alcohol use and common mental disorders (CMDs) co-occur; however, little is known about how the global prevalence of alcohol use compares across different CMDs. We aimed to (i) report global associations of alcohol use (alcohol use disorder (AUD), binge drinking and consumption) comparing those with and without a CMD, (ii) examine how this differed among those with and without specific types of CMDs and (iii) examine how results may differ by study characteristics.

METHODS

We used a systematic review and meta-analysis. Cross-sectional, cohort, prospective, longitudinal and case-control studies reporting the prevalence of alcohol use among those with and without a CMD in the general population were identified using PsycINFO, MEDLINE, PsyARTICLES, PubMed, Scopus and Web of Science until March 2020. Depression, anxiety and phobia were included as a CMD. Studies were included if they used a standardized measure of alcohol use. A random-effects meta-analysis was conducted to generate pooled prevalence and associations of AUD with CMD with 95% confidence intervals (CI). A narrative review is provided for binge drinking and alcohol consumption RESULTS: A total of 512 full-texts were reviewed, 51 included in our final review and 17 in our meta-analyses (n = 382 201). Individuals with a CMD had a twofold increase in the odds of reporting an AUD [odds ratio (OR) = 2.02, 95% CI = 1.72-2.36]. The odds of having an AUD were similar when stratified by the type of CMD (mood disorder: OR = 2.00, 95% CI = 1.62-2.47; anxiety/phobic disorder: OR = 1.94, 95% CI = 1.35-2.78). An analysis of study characteristics did not reveal any clear explanations for between-study heterogeneity (I²  > 80%). There were no clear patterns for associations between having a CMD and binge drinking or alcohol consumption, respectively.

CONCLUSIONS

People with common mental disorders (depression, anxiety, phobia) are twice as likely to report an alcohol use disorder than people without common mental disorders.

Testing both affordability-availability and psychological-coping mechanisms underlying changes in alcohol use during the COVID-19 pandemic

Two theoretical perspectives have been proffered to explain changes in alcohol use during the pandemic: the ‘affordability-availability’ mechanism (i.e., drinking decreases due to changes in physical availability and/or reduced disposable income) and the ‘psychological-coping’ mechanism (i.e., drinking increases as adults attempt to cope with pandemic-related distress). We tested these alternative perspectives via longitudinal analyses of the COVID-19 Psychological Consortium (C19PRC) Study data (spanning three timepoints during March to July 2020). Respondents provided data on psychological measures (e.g., anxiety, depression, posttraumatic stress, paranoia, extraversion, neuroticism, death anxiety, COVID-19 anxiety, intolerance of uncertainty, resilience), changes in socio-economic circumstances (e.g., income loss, reduced working hours), drinking motives, solitary drinking, and ‘at-risk’ drinking (assessed using a modified version of the AUDIT-C). Structural equation modelling was used to determine (i) whether ‘at-risk’ drinking during the pandemic differed from that recalled before the pandemic, (ii) dimensions of drinking motives and the psychosocial correlates of these dimensions, (iii) if increased alcohol consumption was predicted by drinking motives, solitary drinking, and socio-economic changes. The proportion of adults who recalled engaging in ‘at-risk’ drinking decreased significantly from 35.9% pre-pandemic to 32.0% during the pandemic. Drinking to cope was uniquely predicted by experiences of anxiety and/or depression and low resilience levels. Income loss or reduced working hours were not associated with coping, social enhancement, or conformity drinking motives, nor changes in drinking during lockdown. In the earliest stage of the pandemic, psychological-coping mechanisms may have been a stronger driver to changes in adults’ alcohol use than ‘affordability-availability’ alone.

The association between naturalistic use of psychedelics and co-occurring substance use disorders

OBJECTIVE

Classic psychedelics (LSD, psilocybin, and peyote/mescaline) have been used to support addiction treatment in a variety of contexts ranging from ceremonial use to clinical trials. The aim of this study was to test the hypothesis that past naturalistic use of classic psychedelics would be associated with decreased prevalence of substance use disorder, when controlling for known confounders.

METHODS

This cross-sectional study used 2017 NSDUH survey data to evaluate the association between past use of the classic psychedelics LSD, psilocybin and peyote/mescaline and past year substance dependence or abuse. We calculated adjusted odds ratios by multivariate logistic regression, controlling for a range of sociodemographic variables, use of non-psychedelic illicit drugs and mental health related variables.

RESULTS

A total of 56,276 participants were included in this study. Past use of LSD and psilocybin were associated with increased odds of substance dependence or abuse compared to those who had never used psychedelics before, and this was more likely for those who had used LSD more recently. However, prior use of peyote or mescaline was associated with lower odds of past year substance dependence or abuse compared to people who had never used psychedelics before (aOR = 0.68, p < 0.001). Past use of classic psychedelics was not associated with nicotine dependence.

CONCLUSION

Past use of peyote/mescaline was associated with decreased odds of substance use disorder compared to people who had never used psychedelics before, while past use of LSD or psilocybin was not. It remains unclear whether this difference is due to pharmacological differences between these compounds or simply due to the context in which peyote/mescaline are traditionally taken. Future research should investigate why naturalistic use of different psychedelics is associated with different substance use disorder effects.

The Moderating Role of Social Support in the Relationship between Poor Mental Health and Excessive Alcohol Consumption: A Gender-Specific Analysis

Background: Social support can potentially attenuate the positive relationship between poor mental health and excessive drinking. The present study tried to understand: (1) whether there is a gender-specific relationship between poor mental health and excessive drinking; and (2) if and how social support moderates the relationship between poor mental health and excessive drinking. Methods: We analyzed the data from 2016 Behavioral Risk Factor Surveillance System (BRFSS; N = 33,705). Weighted data were stratified by gender and controlled for demographic variables. We assessed poor mental health and social support as correlates of heavy and binge drinking, followed by analyzing the moderation effect of social support X poor mental health interaction terms. Results: Poor mental health is linked with excessive drinking across genders. The interaction analysis shows that social support moderates the effect of ever having a poor mental health day in men's heavy drinking, but the interaction term is not significant in all other excessive drinking models, suggesting that social support may not buffer the negative impact of poor mental health on problem drinking, particularly among women. Conclusion: Individuals with greater mental health challenges are more likely to drink hazardously, regardless of gender. Those who have low level of social support and poor mental health, particularly men, are at risk for heavy drinking. Given the majority of the interaction results is not significant, the study provides limited support for the buffering role of social support between poor mental health and problem drinking.

Role of psychological distress on long-term risky and heavy-episodic drinking patterns in major cities and rural and remote areas

OBJECTIVE

Psychological distress and alcohol consumption are associated but few studies have focused on the association with problematic drinking in semi-urban and rural settings. In this study, we assessed the role of psychological distress on various measures of problematic drinking in urban, semi-urban and rural settings.

DESIGN

Retrospective descriptive study Setting SETTING: National Drug Strategy Household Survey population health survey data PARTICIPANTS: 151,341 Australian residents MAIN OUTCOME MEASURES: Problematic alcohol consumption categorised as either heavy-episodic drinking (defined as drinking 5 or more standard drinks at least once in the last 12 months) or long-term risky drinking (defined as drinking more than 730 standard drinks in the past 12 months) was the outcome variables. Psychological distress was identified from the K10 questionnaire. Participants were grouped into area of residence: urban, semi-urban and rural. Sex differences were also explored.

RESULTS

Poor-to-severe psychological distress was associated with higher odds of both long-term and heavy-episodic drinking. Being male alone increased the risk of both long-term and heavy-episodic drinking in all areas. When stratified by sex, being female and severe levels of psychological distress increased the risk of both long-term risky and heavy-episodic drinking. These risks were greater in non-urban environments.

CONCLUSIONS

Poor mental health outcomes may exacerbate problematic drinking amongst females, especially those living in non-urban environments. Public health campaigns could both target these at-risk groups of females in non-urban settings and also account for the interplay between problematic drinking and mental health.

Alcohol Consumption during the COVID-19 Lockdown Period: Predictors of At-Risk Drinking at Different AUDIT-C Cut-Off Thresholds

During the COVID-19 pandemic, alcohol consumption was largely confined to drinking in the home. There has been little research examining variables associated with risk in home drinking. The study employed an online survey of (n = 1128) individuals who had been recruited for their face recognition skills (n = 838, 70.9% females, mean age 45.05 (12.3 SD)). The main dependent variables were three different AUDIT-C cut-off scores for at-risk drinking: (a) 5 for both genders as recommended by Public Health England, (b) 7 for females and 8 for males (cut-off for students and young people) and (c) 8 for both genders (individuals seeking online help for their drinking). Among the independent variables were gender and age, motivations for home drinking using the Home Drinking Assessment Scale (HDAS), purchasing patterns, context of drinking and health and wellbeing. The predictors following hierarchical logistic regressions were for (a) purchasing alcohol online or at a supermarket and emotional HDAS scores, (b) purchasing alcohol online or at a supermarket and for parties, drinking alone and with other members of the household and emotional and practical reason HDAS scores, (c) as for b with the addition that men were more likely to be at-risk drinkers. At-risk drinking in the pandemic was explained by motivational reasons, purchasing patterns and situational factors.

The Association between Dietary Habits, Substance Use, and Mental Distress among Adults in Southern Norway: A Cross-Sectional Study among 28,047 Adults from the General Population

The aim of the present study was to examine associations between dietary habits, substance use, and mental distress among adults. This cross-sectional study was conducted in 2019 using an online questionnaire and included 28,047 adults (≥18 years) from Southern Norway. Multivariable logistic regression models stratified by gender were used to examine the associations between different lifestyle behaviors and mental distress. The results showed increased odds of mental distress among males and females with low consumption of vegetables (OR:1.26; 95% CI:1.08–1.47 and 1.14; 1.02–1.28) and fish (1.28; 1.12–1.46 and 1.36; 1.22–1.52), and among females, but not males, with high consumption of sugar-sweetened beverages (1.25; 1.06–1.48) compared to those with a healthier consumption of these foods and beverages. The results also showed increased odds of mental distress among male and female smokers (1.38; 1.19–1.60 and 1.44; 1.26–1.64), and among females, but not males, reporting current use of smokeless tobacco (1.20; 1.03–1.40), compared to male and female non-smokers and female non-users of smokeless tobacco. Overall, unhealthy dietary habits, smoking and the use of smokeless tobacco was associated with increased odds of mental distress, but the relationship varied according to gender. Future studies are needed to confirm any possible causal relationships.

Associations of alcohol use, mental health and socioeconomic status in England: Findings from a representative population survey

BACKGROUND

Alcohol use and mental health problems often co-occur, however, little is known about how this varies by type of mental health problem and to what extent associations are explained by socioeconomic status (SES). Our study examined the prevalence and associations of non-drinking, hazardous use, and harmful/probable dependence in individuals who do and do not meet criteria for different mental health problems and whether associations remained after adjustment for SES.

METHODS

A secondary analysis of an English dataset, 2014 Adult Psychiatric Morbidity Survey (N = 7,218), was conducted. The Alcohol Use Disorder Identification Test was used to categorise participants as non-drinking, low risk, hazardous use and harmful/probable dependence. Mental health problems were screened using a range of validated tools. Multinomial logistic regression analyses were used to address study aims.

RESULTS

The prevalence of non-drinking, hazardous and harmful/probable dependence was higher among those meeting criteria for a mental health problem. After adjustment for SES, non-drinking was most common in those meeting criteria for probable psychotic disorder (MOR = 3.42, 95 %CI = 1.74-6.70), hazardous use in those meeting criteria for anti-social personality disorder (MOR = 2.66, 95 %CI = 1.69-4.20) and harmful/probable dependence in those meeting criteria for borderline personality disorder (MOR = 9.77, 95 % CI = 4.81-19.84).

CONCLUSIONS

There were marked increases in the odds of reporting both non-drinking and harmful drinking among those meeting criteria for a mental health problem, particularly more severe problems. Our findings indicate that the relationship between alcohol and mental health is more complex and comorbid alcohol and mental health problems should be treated in parallel with access to both services.

Alcohol consumption and internalising disorders in young adults of ALSPAC: a population-based study

Introduction

Depression and harmful alcohol consumption contribute significantly to the global health burden, but in young adults, this relationship is under-researched and conflicted. The aim of this study was to determine the sex-based prevalence and the association between internalising disorders such as depression and alcohol use disorders.

Method

Using the Avon Longitudinal Study of Parents and Children, we assessed the sex-specific prevalence of International Classification of Diseases, Tenth Revision diagnosed generalised anxiety disorder (GAD), depression and fear-based anxieties (FBA) at 24 years (n=3572). We examined the association between internalising disorders and alcohol consumption using the Alcohol Use Disorder Identification Test for Consumption 5+ threshold and Diagnostic and Statistical Manual on Mental Disorders defined criteria for alcohol dependence.

Results

Women reported more GAD (11.6% vs 6.5%), depression (13.4% vs 6.9%) and FBA (1.3% vs 0.5%) than men (p<0.001). Harmful drinking, after adjustment for sex and socioeconomic status, was associated witha higher prevalence of depression (OR 1.8, 95% CI 1.3 to 2.4, p<0.001), anxiety (OR 1.4, 95% CI 1.0 to 2.0, p<0.001) and FBA (OR 2.4, 95% CI 1.04 to 5.56, p=0.009) compared with lower-risk drinkers. In contrast, hazardous drinking was associated with a lower prevalence of GAD (OR 0.69, 95% CI 0.54 to 0.88) and depression (OR 0.68, 95% CI 0.54 to 0.86) compared with lower-risk drinkers.

Conclusions

Young adults in the UK who drink harmfully are more likely to have depression and other internalising disorders. Further research should test whether there is a J-shaped relationship between alcohol consumption and mental health in young people and whether this varies across the life course.

Change in moderate alcohol consumption and quality of life: evidence from 2 population-based cohorts

BACKGROUND

Although the association of moderate alcohol consumption with specific disorders, such as cardiovascular disease and cancers, has been well documented, the evidence of the broader impact of alcohol consumption on health-related quality of life is less clear. Our objective was to examine the association of drinking patterns with changes in physical and mental well-being across populations.

METHODS

We conducted a multilevel analysis with multivariate responses in the population-representative FAMILY Cohort in the Hong Kong Special Administrative Region, China, to examine the association between alcohol drinking patterns across 2 waves (2009-2013) (i.e., quitters, initiators, persistent drinkers, persistent former drinkers and lifetime abstainers) and changes in physical and mental well-being (Physical and Mental Component Summary of the 12-Item Short Form Health Survey [SF-12]). Analyses were stratified by sex. We validated findings using a nationally representative cohort in the United States, the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC, 2001-2005).

RESULTS

In the FAMILY Cohort (n = 10 386; median follow-up 2.3 yr), the change in mental well-being was more favourable in female quitters than in lifetime abstainers (β = 1.44, 95% confidence interval [CI] 0.43 to 2.45; mean score change of +2.0 for quitters and +0.02 for lifetime abstainers). This association was validated in the NESARC (n = 31 079; median follow-up 3.1 yr) (β = 0.83, 95% CI 0.08 to 1.58; mean score change of -1.1 for quitters and -1.6 for lifetime abstainers).

INTERPRETATION

The change in mental well-being was more favourable in female quitters, approaching the level of mental well-being of lifetime abstainers within 4 years of quitting in both Chinese and American populations.

Associations between interrelated dimensions of socio-economic status, higher risk drinking and mental health in South East London: A cross-sectional study

AIM

To examine patterns of hazardous, harmful and dependent drinking across different socio-economic groups, and how this relationship may be explained by common mental disorder.

METHODS AND FINDINGS

Between 2011-2013, 1,052 participants (age range 17-91, 53% female) were interviewed for Phase 2 of the South East London Community Health study. Latent class analysis was used to define six groups based on multiple indicators of socio-economic status in three domains. Alcohol use (low risk, hazardous, harmful/dependent) was measured using the Alcohol Use Disorders Identification Test and the presence of common mental disorder was measured using the revised Clinical Interview Schedule. Multinomial regression was used to explore associations with hazardous, harmful and dependent alcohol use, including after adjustment for common mental disorder. Harmful and dependent drinking was more common among people in Class 2 'economically inactive renters' (relative risk ratio (RRR) 3.05, 95% confidence interval (CI) 1.07-8.71), Class 3 'economically inactive homeowners' (RRR 4.11, 95% CI 1.19-14.20) and Class 6 'professional renters' (RRR 3.51, 95% CI 1.14-10.78) than in Class 1 'professional homeowners'. Prevalent common mental disorder explained some of the increased risk of harmful or dependent drinking in Class 2, but not Class 3 or 6.

CONCLUSIONS

Across distinct socio-economic groups in a large inner-city sample, we found important differences in harmful and dependent drinking, only some of which were explained by common mental disorder. The increased risk of harmful or dependent drinking across classes which are very distinct from each other suggests differing underlying drivers of drinking across these groups. A nuanced understanding of alcohol use and problems is necessary to understand the inequalities in alcohol harms.

Association of coincident self-reported mental health problems and alcohol intake with all-cause and cardiovascular disease mortality: A Norwegian pooled population analysis

BACKGROUND

The disease burden attributable to mental health problems and to excess or harmful alcohol use is considerable. Despite a strong relationship between these 2 important factors in population health, there are few studies quantifying the mortality risk associated with their co-occurrence in the general population. The aim of this study was therefore to investigate cardiovascular disease (CVD) and all-cause mortality according to self-reported mental health problems and alcohol intake in the general population.

METHODS AND FINDINGS

We followed 243,372 participants in Norwegian health surveys (1994-2002) through 2014 for all-cause and CVD mortality by data linkage to national registries. The mean (SD) age at the time of participation in the survey was 43.9 (10.6) years, and 47.8% were men. During a mean (SD) follow-up period of 16.7 (3.2) years, 6,587 participants died from CVD, and 21,376 died from all causes. Cox models estimated hazard ratios (HRs) with 95% CIs according to a mental health index (low, 1.00-1.50; high, 2.01-4.00; low score is favourable) based on the General Health Questionnaire and the Hopkins Symptom Checklist, and according to self-reported alcohol intake (low, <2; light, 2-11.99; moderate, 12-23.99; high, ≥24 grams/day). HRs were adjusted for age, sex, educational level, marital status, and CVD risk factors. Compared to a reference group with low mental health index score and low alcohol intake, HRs (95% CIs) for all-cause mortality were 0.93 (0.89, 0.97; p = 0.001), 1.00 (0.92, 1.09; p = 0.926), and 1.14 (0.96, 1.35; p = 0.119) for low index score combined with light, moderate, and high alcohol intake, respectively. HRs (95% CIs) were 1.22 (1.14, 1.31; p < 0.001), 1.24 (1.15, 1.33; p < 0.001), 1.43 (1.23, 1.66; p < 0.001), and 2.29 (1.87, 2.80; p < 0.001) for high index score combined with low, light, moderate, and high alcohol intake, respectively. For CVD mortality, HRs (95% CIs) were 0.93 (0.86, 1.00; p = 0.058), 0.90 (0.76, 1.07; p = 0.225), and 0.95 (0.67, 1.33; p = 0.760) for a low index score combined with light, moderate, and high alcohol intake, respectively, and 1.11 (0.98, 1.25; p = 0.102), 0.97 (0.83, 1.13; p = 0.689), 1.01 (0.71, 1.44; p = 0.956), and 1.78 (1.14, 2.78; p = 0.011) for high index score combined with low, light, moderate, and high alcohol intake, respectively. HRs for the combination of a high index score and high alcohol intake (HRs: 2.29 for all-cause and 1.78 for CVD mortality) were 64% (95% CI 53%, 74%; p < 0.001) and 69% (95% CI 42%, 97%; p < 0.001) higher than expected for all-cause mortality and CVD mortality, respectively, under the assumption of a multiplicative interaction structure. A limitation of our study is that the findings were based on average reported intake of alcohol without accounting for the drinking pattern.

CONCLUSIONS

In the general population, the mortality rates associated with more mental health problems and a high alcohol intake were increased when the risk factors occurred together.

Alcohol consumption trajectories and self-rated health: findings from the Stockholm Public Health Cohort

OBJECTIVE

To investigate whether poor self-rated health and psychological distress are differentially associated with drinking trajectories over time.

METHODS

From the Stockholm Public Health Cohort, two subcohorts surveyed in 2002-2010-2014 and 2006-2010-2014 (n=23 794 and n=34 667 at baseline, respectively) were used. Alcohol consumption, self-rated health, psychological distress (measured by General Health Questionnaire-12), lifestyle factors and longstanding illness were assessed by questionnaires. Demographic and socioeconomic variables were obtained by register linkage. Logistic regression was fitted to assess the associations with eight alcohol consumption trajectories, which were constructed among 30 228 individuals (13 898 and 16 330 from the 2002 and 2006 subcohorts, respectively) with measures of consumption at three time points.

RESULTS

Compared with stable moderate drinkers, all other trajectories were associated with poor self-rated health with multiadjusted OR for stable non-drinkers of 2.35 (95% CIs 1.86 to 2.97), unstable non-drinkers (OR=2.58, 95% CI 1.54 to 3.32), former drinkers (OR=2.81, 95% CI 2.31 to 3.41) and stable heavy drinkers (OR=2.16, 95% CI 1.47 to 3.20). The associations were not fully explained by sociodemographic and lifestyle factors and longstanding illness. Former drinking, but no other trajectories, was associated with psychological distress (OR=1.24; 95% CI 1.10 to 1.41).

CONCLUSION

We found a U-shape association between alcohol trajectories and self-rated health, but not with psychological distress. Compared with stable moderate drinking, former drinking was associated with the highest odds of both poor self-rated health and psychological distress. The study confirms the importance of a life-course approach to examining the effect of alcohol consumption on health and highlights the poorer general and mental health status of non-drinkers who were former drinkers.

Moderate alcohol consumption and depression - a longitudinal population-based study in Sweden

BACKGROUND AND AIMS

The interrelationship between alcohol consumption and depression is complex, and the direction of the association is unclear. We investigated whether alcohol consumption influences the risk of depression while accounting for this potential bidirectionality.

METHODS

A total of 10 441 individuals participated in the PART study in 1998-2000, 8622 in 2001-2003, and 5228 in 2010. Participants answered questions on their alcohol consumption, symptoms of depression, childhood adversity, and sociodemographic, socioeconomic, psychosocial, and lifestyle factors. A total of 5087 participants provided repeated information on alcohol consumption. We used marginal structural models to analyze the association between alcohol consumption and depression while controlling for previous alcohol consumption and depressive symptoms and other time-varying confounders.

RESULTS

Non-drinkers had a higher depression risk than light drinkers (≤7 drinks/week) (risk ratio: 1.7; 95% confidence interval 1.3-2.1). Consumers of seven-fourteen drinks/week had a depression risk similar to that of light drinkers. Hazardous drinking was associated with a higher risk of depression than non-hazardous alcohol consumption (risk ratio: 1.8, 95% confidence interval: 1.4-2.4).

CONCLUSION

Light and moderate alcohol consumption and non-hazardous drinking were associated with the lowest risk of subsequent depression after accounting for potential bidirectional effects. Hazardous drinking increased the risk of depression.

Associations of education and income with heavy drinking and problem drinking among men: evidence from a population-based study in Japan

Background

Some studies in Western countries have suggested that education and income are differentially associated with different drinking patterns. This study aimed to examine the associations of education and income with heavy drinking and problem drinking among community-dwelling Japanese men.

Methods

A questionnaire survey was conducted in metropolitan areas in Japan from 2010 to 2011 among residents aged 25 to 50 years; valid responses were received from 2004 men. Drinking patterns were categorized as non-to-moderate drinking, non-problematic heavy drinking, and problem drinking. Multiple logistic regression analyses were conducted to determine whether educational attainment or income was associated with drinking patterns, after adjustment for age, marital status, working status, income/education, self-rated health, and psychological distress.

Results

The study population included 84.4% non-to-moderate drinkers, 8.9% non-problematic heavy drinkers, and 6.7% problem drinkers. Lower educational attainment (high school or less) was significantly associated with increased risks of both non-problematic heavy drinking (odds ratio [OR], 1.80; 95% confidence interval [CI], 1.21–2.67) and problem drinking (OR, 2.06; 95% CI, 1.34–3.16), compared with university education or higher. Lower income (lowest tertile) was significantly associated with a lower risk of non-problematic heavy drinking (OR, 0.66; 95% CI, 0.43–1.00), but not of problem drinking (OR, 0.80; 95% CI, 0.50–1.30), compared with the highest income tertile.

Conclusions

These findings indicate that education and income are differentially associated with alcohol drinking patterns among community-dwelling Japanese men.

Does social capital and a healthier lifestyle increase mental health resilience to disability acquisition? Group-based discrete trajectory mixture models of pre-post longitudinal data

Poor mental health is strongly associated with disability acquisition. Social capital and healthier lifestyles pre-disability onset may help promote mental health resilience (i.e. a state of seemingly being unaffected by the event), or the capacity to 'bounce back', post-acquisition. This paper used a novel methodology (discrete trajectory mixture models) to examine discrete trajectories in mental health before and after disability acquisition in the Household Income Labour Dynamics in Australia (HILDA) survey. Group membership in association with pre-onset social capital and healthy lifestyles were then examined using multinomial logistic regressions. Four discrete trajectory groups were identified in 2904 Australians reporting onset of ongoing disability, with about 28.4% demonstrating mental health resilience. Three other groups were identified, each demonstrating increasingly severe reductions in mental health. No clear 'bounce back' group was observed. Group membership was associated with participants who felt they had 'no-help from others' prior to disability acquisition. Pre-disability acquisition measures of social capital and unhealthy behaviours moderated the association between disability acquisition and mental health trajectories. Social capital was protective only for the respondents who had poorer mental health before disability onset and had less resilience after onset, and long working hours and less resilience were positively associated. Public policies that help to enhance levels of social capital and reduce unhealthy behaviours at a population level may help to promote mental health resilience to adversities such as the acquisition of disability.

Longitudinal prospective associations between psychological symptoms and heavy episodic drinking from adolescence to midlife

AIM

This study examined whether development of psychological symptoms (PS) differed between persons with different longitudinal profiles of heavy episodic drinking (HED) from adolescence to midlife. In addition, the reciprocal associations between PS and HED were studied.

METHODS

Participants of a Finnish cohort study in 1983 at age 16 ( N = 2194) were followed up at ages 22 ( N = 1656), 32 ( N = 1471), and 42 ( N = 1334). HED was assessed with frequency of intoxication (16-22 years) and having six or more drinks in a session (32-42 years). Using latent class analysis, the participants were allocated to steady high, increased, moderate, and steady low groups according to their longitudinal profiles of HED. The PS scale (16-42 years) covered five mental complaints. The latent growth curve of PS was estimated in the HED groups for comparisons. In addition, the prospective associations between symptoms and HED were examined using cross-lagged autoregressive models.

RESULTS

PS grew from 16 to 32 years, but declined after that, with women having higher level of PS than men. PS trajectory followed a path at highest and lowest level in the steady high and steady low HED groups, respectively. Symptoms predicted later HED, but the association in the opposite direction was not found.

CONCLUSIONS

The more the HED trajectory indicated frequent HED, the higher was the level of PS throughout the follow-up. Results support the self-medication hypothesis, suggesting that alcohol is used to ease the burden of PS. More attention should be paid to alcohol use of people with mental symptoms in health services.

The Cedar Project: exploring determinants of psychological distress among young Indigenous people who use drugs in three Canadian cities

BACKGROUND

Mental health and wellbeing, including addressing impacts of historical trauma and substance use among young people, has been identified as a key priority by Indigenous communities and leaders across Canada and globally. Yet, research to understand mental health among young Indigenous people who have used drugs is limited.

AIMS

To examine longitudinal risk and strengths-based factors associated with psychological distress among young Indigenous people who use drugs.

METHOD

The Cedar Project is an ongoing cohort study involving young Indigenous people who use drugs in Vancouver, Prince George, and Chase, British Columbia, Canada. This study included participants who completed the Symptom Checklist-90-Revised, returned for follow-up between 2010 and 2012, and completed the Childhood Trauma Questionnaire. Adjusted linear mixed-effects models estimated effects of study variables on changes in area T-scores of psychological distress.

RESULTS

Of 202 eligible participants, 53% were women and the mean age was 28 years. Among men, childhood maltreatment (emotional abuse, physical abuse, sexual abuse, physical neglect), any drug use, blackouts from drinking, and sex work were associated with increased distress. Among women, childhood maltreatment (emotional abuse, physical abuse, physical neglect), blackouts from drinking, and sexual assault were associated with increased distress, while having attempted to quit using drugs was associated with reduced distress. Marginal associations were observed between speaking their traditional language and living by traditional culture with lower distress among men.

CONCLUSION

Culturally safe mental wellness interventions are urgently needed to address childhood trauma and harmful coping strategies that exacerbate distress among young Indigenous people who use drugs.

Trajectories of alcohol use in the UK military and associations with mental health

INTRODUCTION

There are higher levels of alcohol misuse in the military compared to the general population. Yet there is a dearth of research in military populations on the longitudinal patterns of alcohol use. This study aims to identify group trajectories of alcohol consumption in the UK military and to identify associations with childhood adversity, deployment history and mental disorder.

METHODS

Data on weekly alcohol consumption across an eight year period and three phases of a UK military cohort study (n=667) were examined using growth mixture modelling.

RESULTS

Five alcohol trajectory classes were identified: mid-average drinkers (55%), abstainers (4%), low level drinkers (19%), decreasing drinkers (3%) and heavy drinkers (19%). Alcohol consumption remained stable over the three periods in all classes, other than in the small decreasing trajectory class. Individuals in the heavy drinking class were more likely to have deployed to Iraq. Abstainers and heavy drinkers were more likely to report post-traumatic stress disorders at baseline compared to average drinkers.

CONCLUSIONS

Heavy drinkers in the UK military did not change their drinking pattern over a period of eight years. This highlights the need to develop effective preventive programmes to lessen the physical and psychological consequences of long-term heavy alcohol use. Individuals with a mental health problem appeared more likely to either be drinking at a high level or to be abstaining from use.

Alcohol and depression: Evidence from the 2014 health survey for England

BACKGROUND

A relatively large body of literature examines the association between depression and alcohol consumption, with evidence suggesting a bidirectional causal relationship. However, the endogeneity arising from this reverse causation has not been addressed in the literature.

METHODS

Using data on 5828 respondents from the Health Survey for England (HSE), this study revisits the relationship between alcohol and depression and addresses the endogenous nature of this relationship. We use information on self-assessed depression, and control for endogeneity using the Lewbel two-staged least square (2SLS) estimation technique.

RESULTS

We find that drinking alcohol promotes depression, and this is consistent across several measures of drinking behaviour including the amount of alcohol consumed, consumption intensity, alcohol dependence and risk of dependence.

CONCLUSION

While drinking may be generally accepted and in the case of England, part of the culture, this has costs in terms of both physical and mental health that ought not to be ignored. While public policy has predominantly focused on the physical aspects of excessive alcohol consumption it is possible that these policies will also have a direct positive spillover in terms of the mental health costs, through the impact of lower alcohol consumption on quality of life and wellbeing.

The association between levels of alcohol consumption and mental health problems and academic performance among young university students

PURPOSE

Mental health problems and harmful alcohol consumption have been found to be high among young university students compared to the general population in Australia. This research aimed to investigate the association between levels of drinking and mental health problems and academic performance among university students aged 18 to 24 years.

METHODS

This study used a quantitative cross-sectional design using data that were collected in 2014 as part of the Youth Alcohol Project (YAP). Participants were randomly drawn from a cross sectional sample of 6000 undergraduate students. Included in the study were only students who were within the age of 18-24, undergraduate, and internally enrolled at the main campus. A total of 2518 undergraduate students aged 18 to 24 years who were enrolled internally at Curtin University Bentley campus were randomly recruited. Data were collected through an online survey. Students were invited to participate in the study through their student email address. The email invitations coincided with the release of semester results to increase the likelihood of students accessing their emails. A further 628 students were randomly recruited through face to face intercept survey during the campus market days. Data were collected by trained research assistants. Validated instruments were used to collected data on levels of alcohol consumption, mental health, and academic performance.

RESULTS

A considerable proportion of participants (44%) reported consuming alcohol at hazardous or harmful levels. Multiple logistic regression analysis showed that students who were consuming alcohol at hazardous levels were 1.2 times more likely to report psychological distress than those with lower levels of alcohol consumption (aOR 1.2, 95% CI: 1.1-1.5). In addition, being late for class (aOR 1.7, 95% CI:1.1-2.4), missing classes (aOR = 2.6, 95% CI: 1.9-2.6), inability to concentrate in class (aOR = 2.6, 95% CI: 1.9-3.4), and inability to complete assignments (aOR = 3.5, 95% CI 2.0-6.0) independently predicted for moderate or hazardous alcohol consumption.

CONCLUSION

The study shows that a considerable proportion of undergraduate students at university consume alcohol at hazardous or harmful levels. In addition, high levels of alcohol consumption are associated with poor academic performance and mental health outcomes among students. The results of the study warrant multi-strategy interventions that focus on policy, organisational, educational, environmental and economic strategies that will help to reduce alcohol related harms among university students.

Onset of Alcohol Use Disorders and Comorbid Psychiatric Disorders in a Military Cohort: Are there Critical Periods for Prevention of Alcohol Use Disorders?

Alcohol use disorders (AUD) are commonly comorbid with anxiety and mood disorders; however, a strategy for AUD prevention remains unclear in the presence of three competing etiological models that each recommends different high-risk groups. Therefore, the investigation of the three hypotheses in a characteristically unique cohort is critical to identifying pervasive characteristics of AUD that can inform a universal prevention strategy. The current study evaluated the temporality and onset of comorbid AUD and psychiatric disorders in a representative sample of 528 Ohio Army National Guard soldiers using structured clinical interviews from 2009 to 2012. We examined temporality both statistically and graphically to identify patterns that could inform prevention. General estimating equations with dichotomous predictor variables were used to estimate odds ratios between comorbid psychiatric disorders and AUDs. An annualized rate of 13.5 % persons per year was diagnosed with any AUD between 2010 and 2012. About an equal proportion of participants with comorbid psychiatric disorders and AUD initiated the psychiatric disorder prior to the AUD and half initiated the psychiatric disorder after the AUD. Regardless of onset, however, the majority (80 %) AUD initiated during a short interval between the ages of 16 and 23. Focused primary prevention during this narrow age range (16-23 years) may have the greatest potential to reduce population mental health burden of AUD, irrespective of the sequencing of comorbid psychiatric disorder.

Longitudinal Mediation Modeling of Unhealthy Behaviors as Mediators between Workplace Demands/Support and Depressive Symptoms

Lifestyle has been regarded as a key pathway through which adverse psychosocial working characteristics can give rise to long-term health problems. The purpose of this study was to estimate the indirect/mediated effect of health behaviors in the longitudinal work characteristics-depression relationship. The analyses were based on the Swedish Longitudinal Occupational Survey of Health, including 3706 working participants with repeat survey measures on four occasions (2008, 2010, 2012 and 2014). Psychosocial work characteristics including demands and social support were analyzed in relation to depressive symptoms. Autoregressive longitudinal mediation models using structural equation modeling were used to estimate the intermediate effects of unhealthy behaviors including current smoking, excessive alcohol consumption, unhealthy diet and physical inactivity. Both workplace demands and social support were related to later depressive symptoms. In bivariate models we found no significant paths from workplace demands to health behaviors, but two out of three significant time-specific paths from workplace support to excessive drinking and from excessive drinking to depressive symptoms. Social support was also associated with subsequent unhealthy diet, and one path from unhealthy diet to depressive symptoms was found. However, despite indications of certain longitudinal relationships between psychosocial working conditions and health behaviors as well as between health behaviors and depressive symptoms, no significant intermediate effects were found (p>0.05). We conclude that changes in unhealthy behaviors over a period of two years are unlikely to act as strong intermediaries in the longitudinal relationship between job demands and depressive symptoms and between social support and depressive symptoms.

Binge drinking and subsequent depressive symptoms in young women in Australia

BACKGROUND

The long-term impact of binge drinking on subsequent depressive symptoms is unclear. The aims were to identify longitudinal patterns of binge drinking and whether binge drinking preceded depressive symptoms in the short-term (1-6 years) and long-term (10-15 years).

METHODS

Longitudinal data from 1996, 2000 and 2009 mailed surveys of 8,197 women in the 1973-78 cohort of the Australian Longitudinal Study on Women's Health. Latent class analysis was used to identify binge drinking patterns and logistic regression to estimate associations with subsequent depressive symptoms.

RESULTS

Five binge drinking trajectories were identified with predicted proportions of women who were very infrequent (24%), fluctuating infrequent (17%), frequent (17%), very frequent (26%) or extremely frequent binge drinkers (16%) between 16 and 21 years. At 22-27 years, depressive symptoms were significantly higher for extremely frequent binge drinkers (31% versus 21% in the short-term; 22% versus 16%-18% in the long-term) than for less frequent bingers. Unadjusted odds of depressive symptoms were 1.70 (95%CI:1.38;2.08) times for extremely frequent binge drinkers than very infrequent bingers and were 1.30 (95%CI:1.04;1.63) after adjusting for demographics, relationships and experience of violence. At 31-36 years, the odds of depressive symptoms were 1.34 (95%CI:1.09-1.64) times for extremely frequent than very infrequent binge drinkers, but were not significant after adjusting for relationships and violence.

CONCLUSIONS

Extremely frequent binge drinking (more than weekly) in late adolescence appears to elevate the risk of subsequent depressive symptoms in young women in their early twenties and thirties, emphasising the need for preventive strategies to curb binge drinking.

Bidirectional associations between alcohol consumption and health-related quality of life amongst young and middle-aged women

BACKGROUND

Evidence from cross-sectional studies has suggested a positive association between moderate alcohol consumption and health-related quality of life but prospective data remain scarce.

OBJECTIVES

To examine the bidirectional relationships between alcohol consumption and health-related quality of life using a longitudinal study design.

METHODS

A total of 92 448 participants of the Nurses' Health Study II reported their alcohol consumption (in 1991, 1995, 1999 and 2003) and health-related quality of life (in 1993, 1997 and 2001). Using generalized estimating equations, we modelled the physical and mental component summary (PCS and MCS) scores as a function of alcohol consumption 2 years earlier (n = 88 363) and vice versa (n = 84 621).

RESULTS

Greater alcohol consumption was associated with better PCS scores 2 years later in a dose-response manner up to ~1 serving daily [mean difference (β) = 0.67 ± 0.06 PCS units, for moderate versus infrequent drinkers]. After adjustment for previous PCS, a similar but attenuated pattern was observed (β = 0.33 ± 0.07). Moderate alcohol consumption was not related to MCS, whereas moderate-to-heavy alcohol consumption was associated with lower MCS scores (β = -0.34 ± 0.15). Higher PCS scores were associated with greater alcohol consumption 2 years later, also after adjustment for previous alcohol consumption (β = 0.53 ± 0.05 g day(-1) ). MCS was not associated with alcohol consumption 2 years later.

CONCLUSION

Amongst young and middle-aged women, moderate alcohol intake was associated with a small improvement in physical health-related quality of life 2 years later and vice versa. Moderate alcohol consumption was not associated with mental health-related quality of life in either direction.
