Alcohol use in adolescence and risk of disability pension: a 39 year follow-up of a population-based conscription survey

Assessment of the Prevalence of Alcoholic Beverage Consumption and Knowledge of the Impact of Alcohol on Health in a Group of Polish Young Adults Aged 18-35: A Cross-Sectional Study

Alcoholic beverages are widely consumed worldwide, especially by young adults. Their excessive consumption is associated with numerous health, social and financial damages. The level of knowledge of young adults about the health effects of consuming alcoholic beverages is low, and research in this area is conducted on small, unrepresentative groups. This cross-sectional study aimed to assess the prevalence of alcoholic beverage consumption and the level of knowledge about the impact of ethyl alcohol on health in a group of people aged 18−35. The survey results indicate that the majority of respondents regularly consume alcoholic beverages (94.6%), and they are at a low risk of excessive consumption (p < 0.0001). The most frequently chosen alcoholic beverage in the studied group was beer, and the least chosen one was vodka. The main motive for reaching for alcoholic beverages was the desire to improve mood. Respondents did not indicate significant changes in alcohol consumption during the COVID-19 pandemic, but participants in the high-risk group more often indicated an increase in alcohol consumption (p = 0.0025). The analysis of the level of knowledge showed that the participants in the study had an average or low level of knowledge about the effects of ethanol on health, with no significant relationships between the study groups. The obtained results indicate a strong need for the continuous education of young people on the effects of the excessive consumption of alcoholic beverages on the body, with particular emphasis on the consequences of using alcohol as a mood-enhancing agent.

Gender specific early treatment for women with alcohol addiction (EWA): Impact on work related outcomes. A 25-year registry follow-up of a randomized controlled trial (RCT)

BACKGROUND

Alcohol contributes to substantial economic burden, at both individual and community levels. We investigated the effect of the Early treatment for Women with Alcohol Addiction (EWA) treatment program on sickness leave, income, unemployment and early retirement pension up to 25 years following intake to treatment.

METHODS

The EWA RCT included 200 women with alcohol use disorder from 1983 to 1984 at the Karolinska University Hospital, Sweden. Participants were randomized to the EWA program, a two-year specialized woman only treatment including psychiatric, interpersonal and family concerns, or treatment as usual (TAU) in a mixed gender setting. We followed the participants in the RCT from 1985 to 2009 through linkage with a national labor market registry and applied latent growth curve modeling to estimate level and change in sickness leave, income, unemployment and early retirement pension.

FINDINGS

Relative to TAU, the EWA group had less increase in sickness leave up to 21 years after treatment. Overall, we found no differences in income between treatment groups, yet, a two-year interval analysis showed greater rise in income up to 8 years after treatment for the EWA group. Level and change in unemployment and early retirement pension did not differ between treatment groups.

CONCLUSIONS

Gender specific treatment emphasizing psychiatric, interpersonal and family issues for women with alcohol addiction had long-term positive effects on sickness leave and income. These findings complement positive clinical outcomes of the EWA treatment program on drinking patterns, mental health and mortality.

Employment trajectories among those treated for alcohol use disorder: A register-based cohort study

BACKGROUND AND AIMS

Employment during and following treatment for alcohol use disorder (AUD) is important for the individual's health and well-being and for reducing the societal costs associated with benefit payments. Nonetheless, this is an under-researched topic. This study aimed to identify trajectories of labour force participation among people enrolled in AUD treatment and describe the characteristics of those following contrasting pathways.

DESIGN

Using trajectory analysis, we modelled employment trajectory groups among AUD patients during the year of treatment entry and the 4 subsequent years, applying Norwegian longitudinal register data.

SETTING

Norway.

PARTICIPANTS

Patients who entered treatment with AUD as the primary diagnosis during 2009 and 2010 (9000 patients, age 20-61 years).

MEASUREMENTS

The outcome variable 'labour force attachment' was measured as being in full-time employment, partly employed, on temporary welfare benefits or on permanent disability pension. Predictors were age, gender, education and comorbid mental health and drug use disorders.

FINDINGS

We distinguished six employment trajectories among AUD patients: 15.8% were on permanent disability pension throughout, 8.7% exited the labour force on permanent disability pension during the observation period, 32.1% had a medium attachment throughout follow-up, and 9.2% had a decreasing attachment; 23.3% had a high labour force attachment throughout, and 10.9% experienced increasing attachment. High attachment throughout was negatively associated with being female (P < 0.001), having lower educational attainment (P < 0.001), and having comorbid mental health (P < 0.001) and drug use disorders (P < 0.001).

CONCLUSIONS

Norwegian patients treated for alcohol use disorder in 2009 and 2010 followed six employment trajectories during the 5 years following treatment entry and had lower labour force participation than the general population. Nearly a quarter had a high labour force attachment throughout treatment, which was positively associated with being male, having higher educational attainment and having fewer comorbid mental health and drug use disorders.

Disability Status, Unemployment, and Alcohol-Related Liver Disease (ALD) Mortality: A Large Sample Individual Level Longitudinal Study

Purpose

Unlike previous research, we evaluate disability within expanded employment status factors and stratify gender, race and ethnicity in alcohol-related liver disease (ALD) mortality in a large sample individual level longitudinal study.

Materials and Methods

The National Longitudinal Mortality Study (NLMS) was used covering the period 1990–2011. Statistical analysis involved the use of proportional hazards regression on a sample of almost 1.4 million people aged 18 and older, of whom 2638 died of ALD by the end of the follow-up period.

Results

With expanded employment status factors, disability (HR=3.76 [95%] CI 3.22, 4.39), unemployment (HR=1.90, CI 1.56, 2.31), and those not otherwise in the labor force (HR=2.31, CI 2.08, 2.56) were strongly related to ALD mortality compared to the employed. When stratified, gender, race, and ethnicity were not important modifiers in the relationships between disability, unemployment, those not in the labor force and subsequent ALD mortality. Consistent with other studies, males, minority status, living in a highly urban area, renting as opposed to owning a home, lower educational attainment, marital statuses other than marriage, low income, and age were related to ALD mortality.

Conclusion

In addition to unemployment which has been previously studied in a large longitudinal sample, disabled people who were unable to work and those not looking for work had a higher risk of ALD mortality. Alcohol consumption, abuse and morbidity in these populations are of considerable clinical concern.

Alcohol Use Disorders in Adolescents

Alcohol use during adolescence is an important and modifiable health risk behavior given the significant acute consequences and long-term impacts on the developing brain. Alcohol is the most common substance used by young adults 12 to 17 years old, with binge drinking, polysubstance use, and co-occurring mental health disorders posing particular concerns in this age group. Physicians can play a crucial role in screening and responding to alcohol use, with targeted brief interventions designed to delay or decrease use.

Predictors of employment in young adults with psychiatric work disability

AIM

Mental disorders are the leading cause of work disability among young adults in the industrialized world. Factors predicting employment after long-term psychiatric work disability are largely unknown.

METHODS

We linked personal and clinical information from the benefit applications and medical certificates of 1163 young adults (18-34 years) with a new-onset fixed-term psychiatric disability pension in 2008 with employment records between 2005 and 2013. The outcomes were starting employment during and being employed at the end of follow-up.

RESULTS

Of the participants, 48% had been employed during and 22% were employed at the end of follow-up. Sustained employment history, university education (master's degree) and no recorded psychological symptoms in childhood were associated with both subsequent employment outcomes. Women and participants under 25 years were more likely to start employment. Depression and other mental disorders (vs psychotic diagnose) and having no comorbid mental disorders or substance abuse were associated with employment at the end of follow-up.

CONCLUSIONS

Sustained employment history, university education and no recorded psychological symptoms during childhood predict a return to employment among young adults after a fixed-term psychiatric work disability pension. Pro-active interventions in psychological problems during childhood could enhance employment after a period of work disability.

Health-related lifestyles and obesity among adults with and without disability in Australia: Implication for mental health care

BACKGROUND

Numerous studies have reported people with disabilities are more likely to be obese and engaged in unhealthy lifestyles. Few studies explored the mechanism of health-related lifestyles and obesity among people with disabilities.

OBJECTIVE

We aimed to investigate health-related lifestyles and obesity in relation to disability among Australian adults. We further aimed to explore the potential mediating effect of psychological distress for disability in relation to health related lifestyles and obesity.

METHODS

Using the National Health Survey conducted in 2015 in Australia, we considered non-institutionalised adult participants (aged 18 + years old) as our study population (n = 11,598). Study outcomes included currently smoking, smoking daily, alcohol consumption, physical exercises, and obesity. We considered high psychological distress (Kessler 10 scores ≥ 22) a potential mediator for the disability-lifestyles and disability-obesity associations. Sample weights were calculated allowing for complex survey design. Adjusted Odds Ratios and 95% Confidence Intervals were evaluated using weighted Logistic regression models.

RESULTS

Compared to their disability-free counterparts, people with disabilities were more likely to be current smokers (aOR: 1.26, 95%CI: 1.08-1.47) and have obesity problems (1.44, 1.27-1.64), and were less likely to do physical exercises (0.67, 0.58-0.77), after controlling for socio-environmental factors. In the presence of high psychological distress, the disability-smoking association was no longer significant, and associations of disability-exercise (0.72, 0.62-0.84) and disability-obesity (1.38, 1.22-1.57) were influenced but remained significant.

CONCLUSION

High psychological distress demonstrated important mediating effects. Tailored mental health care for people with disabilities might have the utility to reduce unhealthy behaviors.

Social class, social mobility and alcohol-related disorders in Swedish men and women: A study of four generations

Objectives

To investigate whether and how social class and social mobility in grandparents and parents predict alcohol-related disorders (ARDs) in males and females aged 12+ years, and whether intergenerational social prediction of ARDs varies across time periods.

Methods

The study sample included four successive generations (G) of Swedish families from the Uppsala Birth Cohort Multigenerational Study: G0 born 1851–1912; G1 born 1915–1929; G2 born 1940–1964 and G3 born 1965–1989. Two study populations were created, each consisting of grandparents, parents and offspring: population I ‘G0-G1-G2’ (offspring n = 18 430) and population II ‘G1-G2-G3’ (offspring n = 26 469). Registers and archives provided data on ancestors’ socio-demographic factors and ARD history, together with offspring ARD development between 1964–2008. Cox regression models examined the hazard of offspring ARD development according to grandparental social class and grandparental-to-parental social trajectories, controlling for offspring birth year, grandmother’s and mother’s marital status and parental ARDs.

Results

Disadvantaged grandparental social class predicted increased ARD risk in offspring in population I, although the effect attenuated and became non-significant in males after adjusting for parental characteristics (adjusted hazard ratio (HR) = 1.80 (95%CI; 1.07, 3.03) in females, HR = 1.32 (95%CI; 0.93, 1.89) in males). In population II, no increase in ARD risk by grandparental social was evident. In both populations, males were at the highest ARD risk if both parents and grandparents belonged to disadvantaged social class (population I: HR = 1.82 (95%CI; 1.22–2.72); population II: HR = 1.68 (95%CI; 1.02–2.76)).

Conclusions

Intergenerational social patterning of ARDs appears to be time-contextual and gender-specific. The role of grandparental social class in developing ARDs in grandchildren seems to decline over time, while persistent grandparental-to-parental social disadvantage remains associated with higher ARD risk in males. When targeting higher risk groups, continuity of familial social disadvantage, particularly among males, should be considered.

Health, lifestyle and employment beyond state-pension age

Background

The factors influencing one’s choice to retire vary, with financial and health considerations being some of the main factors impacting or associated with people’s timing of retirement. The aim of the study is to investigate the differences in current health and health-related behaviours, such as smoking, drinking and exercising, between people who kept on working beyond state-pension age and those who retired before or at state-pension age.

Methods

Data from six waves (2003, 2008–2012) of the Scottish Health Survey (SHeS) are used. Descriptive analyses were used to characterise the population. Multivariate logistic regression was undertaken to analyse the relationship between retirement groups and gender, age, deprivation, marital status, housing tenure, general health, longstanding illness, cigarette smoking status, amount of exercise and mental health, using Stata.

Results

Reporting poor self-rated health or having a long-standing illness was associated with increased odds of retiring before state pension age (SPA) in groups with a medium deprivation profile in almost all the survey years. For the least deprived there was little evidence of an association between poor health and extended-working-life, while significant associations were observed for the most deprived. An increasing trend was observed for both genders in the number of people extending their working life. Similar associations between reporting poorer self-rated health and extended working lives were observed for men and women. Distinct gender differences were observed for the associations with reporting poor mental health and no exercise. In the adjusted models, both were significantly associated with retiring at or before SPA in almost every year for women, whereas no significant associations were observed (except in 1 year) for men.

Conclusions

This study shows an increasing trend in the number of people extending their working lives and demonstrates significant associations between health and lifestyle behaviours and employment status past SPA. The results suggest that good health – both physically and mentally – along with either a need or a want to stay in employment could be important reasons for continuing to work beyond SPA.

Effects of increased alcohol availability during adolescence on the risk of all-cause and cause-specific disability pension: a natural experiment

AIM

To test if being exposed to increased alcohol availability during adolescence is associated with an increased risk of receiving disability pension due to all-cause, alcohol use disorders and mental disorders.

DESIGN

Register-based population-based study using a natural experiment setting, the alcohol policy change in Sweden (1967-68), with increased access to strong beer in a narrow time window and geographical area. The individuals exposed to the policy change were compared with non-exposed individuals living in the rest of Sweden, excluding a border area.

SETTING

Sweden.

PARTICIPANTS

A total of 518 810 individuals (70 761 in the intervention group; 448 049 in the control group) born 1948-1953, aged 14-20 years during the policy change.

MEASUREMENTS

Date and diagnosis of the outcome variable of disability pension due to all-cause, alcohol use disorders and mental disorders were obtained from the Swedish National Social Insurance Agency database from 1971 to 2013. Individual and family level socio-demographic and health-related covariates, as well as a regional level covariate, were included.

FINDINGS

Compared with the control group, adolescents exposed to the alcohol policy change were at an increased risk of receiving disability pension due to all-causes [hazard ratio (HR) = 1.09, 95% confidence interval (CI) = 1.07-1.11], alcohol use disorders (HR = 1.17, 95% CI = 1.05-1.30) and mental disorders (HR = 1.19, 95% CI = 1.15-1.23).

CONCLUSION

In Sweden, a natural experiment with a 43-year follow-up suggests that exposure to increased alcohol availability during adolescence is associated with an increased risk of receiving a disability pension due to all-cause, alcohol use disorder and mental disorder diagnoses.

Cannabis, Tobacco, Alcohol Use, and the Risk of Early Stroke: A Population-Based Cohort Study of 45 000 Swedish Men

BACKGROUND AND PURPOSE

Current knowledge on cannabis use in relation to stroke is based almost exclusively on clinical reports. By using a population-based cohort, we aimed to find out whether there was an association between cannabis use and early-onset stroke, when accounting for the use of tobacco and alcohol.

METHODS

The cohort comprises 49 321 Swedish men, born between 1949 and 1951, who were conscripted into compulsory military service between the ages of 18 and 20. All men answered 2 detailed questionnaires at conscription and were subject to examinations of physical aptitude, psychological functioning, and medical status. Information on stroke events up to ≈60 years of age was obtained from national databases; this includes strokes experienced before 45 years of age.

RESULTS

No associations between cannabis use in young adulthood and strokes experienced ≤45 years of age or beyond were found in multivariable models: cannabis use >50 times, hazard ratios=0.93 (95% confidence interval [CI], 0.34-2.57) and 0.95 (95% CI, 0.59-1.53). Although an almost doubled risk of ischemic stroke was observed in those with cannabis use >50 times, this risk was attenuated when adjusted for tobacco usage: hazards ratio=1.47 (95% CI, 0.83-2.56). Smoking ≥20 cigarettes per day was clearly associated both with strokes before 45 years of age, hazards ratio=5.04 (95% CI, 2.80-9.06), and with strokes throughout the follow-up, hazards ratio=2.15 (95% CI, 1.61-2.88).

CONCLUSIONS

We found no evident association between cannabis use in young adulthood and stroke, including strokes before 45 years of age. Tobacco smoking, however, showed a clear, dose-response shaped association with stroke.

High Job Demands, Job Strain, and Iso-Strain are Risk Factors for Sick Leave due to Mental Disorders: A Prospective Swedish Twin Study With a 5-Year Follow-Up

OBJECTIVE

To investigate whether psychosocial work environment and health behaviors are risk factors for sick leave due to mental disorders, and whether familial confounding (genetics and shared environment) explains the associations.

METHODS

Respondents (n = 11,729), given to complete a questionnaire in 2004 to 2006, were followed up approximately 5 years for sick leave spells due to mental disorders, using national registry data. Data were analyzed using logistic regression, and conditional logistic regression for twin pairs discordant for sick leave (cotwin control).

RESULTS

High job demands, job strain, and iso-strain were independent risk factors for sick leave due to mental disorders. Familial factors seem to be of importance in the associations between job support, smoking, a combination of unhealthy behaviors and sick leave.

CONCLUSIONS

Improving the psychosocial work environment may be effective in preventing sick leave due to mental disorders.

Attachment to employment and education before work disability pension due to a mental disorder among young adults

BACKROUND

We examined attachment to employment and education among young adults before they were granted a fixed-term work disability pension due to psychiatric diagnosis, and the factors associated with this attachment.

METHODS

The data comprised all persons aged 18-34 who received a new-onset fixed-term disability pension compensation due to a mental disorder in Finland in 2008 (N = 1163). The data were derived from pension applications and the enclosed medical records, and were linked to employment records from a period of three years before the disability pension. We analysed the factors associated with attachment to employment or education with log-binomial regression analysis.

RESULTS

Fifty percent of the participants were attached to employment or education before work disability pension. The attached were more often women; had higher basic and vocational education; had mood disorder rather than psychosis diagnosis as a primary diagnosis; and had no record of harmful alcohol use or drug use, or recorded symptoms of mental disorders already at school-age.

CONCLUSIONS

The level of attachment to employment or education before work disability pension is low among young adults with mental disorders and several risk factors predict poor attachment; severe or comorbid mental disorder, early-life psychiatric morbidity, substance use, male sex, low basic education, and lacking vocational education.

Devil in disguise: Does drinking lead to a disability pension?

OBJECTIVES

To examine whether alcohol consumption in adulthood is related to the incidence of receiving a disability pension later in life.

METHODS

Twin data for Finnish men and women born before 1958 were matched to register-based individual information on disability pensions. Twin differences were used to eliminate both shared environmental and genetic factors. The quantity of alcohol consumption was measured as the weekly average consumption using self-reported data from three surveys (1975, 1981 and 1990). The disability pension data were evaluated from 1990-2004.

RESULTS

The models that account for shared environmental and genetic factors reveal that heavy drinkers are significantly more likely to receive a disability pension than moderate drinkers or constant abstainers. Heavy drinking that leads to passing out is also positively related to receiving a disability pension. The results were robust to the use of potential confounders that twins do not share, such as education years, the number of chronic diseases, physical activity at work and leisure, and stressful life events.

CONCLUSION

Drinking profiles in early adulthood are an important predictor of receiving a disability pension later in life.

Clustering of adversity in young adults on disability pension due to mental disorders: a latent class analysis

PURPOSE

Mental disorders are the leading cause of work disability among young adults. This study examined whether distinct classes could be identified among young adults on the basis of medical history before receiving a disability pension due to a mental disorder.

METHODS

Medical history was obtained from pension applications and attached medical certificates for 1163 individuals aged 18-34 years who, in 2008, received a disability pension due to a mental disorder. Using latent class analysis, 10 clinical and individual adversities and their associations with sex, age and diagnostic category were examined.

RESULTS

Three classes were identified: childhood adversity (prevalence, 33%), comorbidity (23%), and undefined (44%). The childhood adversity class was characterized by adverse events and symptoms reported during childhood and it associated with depressive disorders. The comorbidity class was characterized by comorbid mental disorders, suicide attempts and substance abuse and associated with younger age and bipolar disorder. The undefined class formed no distinct profile; individuals in this class had the lowest number of adversities and it associated with psychotic disorders.

CONCLUSIONS

The identification of subgroups characterized by childhood circumstances and comorbidity may help planning of prevention and support practices for young adults with mental disorders and risk of work disability.

Harm to Others from Substance Use and Abuse: The Underused Potential in Nationwide Registers

This article considers the potential in using nationwide registers to study harm to others from substance use and abuse. The advantages of using registry data include the opportunity to include the data on the entire population nationwide and continuously updated longitudinal datasets; they allow for studying small subpopulations and have little missing data. Personal identification numbers and family numbers enable linkage of data from different registers. Such datasets can include extensive information on individual and family levels. In this article, we provide an introduction to nationwide registers and explain how they can be applied to investigate two types of third-party harms: harm to children and harm to partners/spouses from substance use and abuse in parents and partners/spouses. Finally, we discuss challenges, benefits, and ethical considerations regarding the use of such data.

Fathers' intelligence measured at age 18-20 years is associated with offspring smoking: linking the Swedish 1969 conscription cohort to the Swedish Survey of Living Conditions

Background

An association between lower IQ of parents, measured early in life, and smoking among their offspring has been reported. The extent to which other background factors account for this association is unknown.

Methods

Data on IQ, smoking, mental health, social class, parental divorce and social problems in a cohort of men born during 1949–1951 and conscripted for military service in 1969 were linked to smoking data on 682 offspring interviewed in the Swedish Surveys of Living Conditions 1984–2009.

Results

In an age-adjusted model, a one-step decrease on a stanine scale was associated with an OR of 1.19 (95% CI 1.04 to 1.35) for offspring smoking. Adjusting for father's socioeconomic background and smoking, mental illness and social problems in youth only marginally lowered the OR's.

Conclusions

Lower IQ among fathers measured at ages 18–20 years was associated with smoking in their offspring. The association was not explained by father's social class in childhood or a higher prevalence of mental illness, social problems or smoking measured among the fathers in their late adolescence.

Cigarette smoking and alcohol use as predictors of disability retirement: A population-based cohort study

BACKGROUND

This study investigated how cigarette smoking and alcohol use predict disability retirement.

METHODS

Data from the longitudinal nationwide Finnish Twin Cohort study were analyzed, with clustered study design applied when computing 95% confidence intervals (CI). The sample included 21,719 individuals. Smoking and alcohol use were assessed with a questionnaire in 1975. Registry data on retirement events up till end of 2004 were obtained from the Social Insurance Institution and the Finnish Centre for Pensions.

RESULTS

Disability pension was granted to 4251 participants. Among men, adjusted for age and alcohol use, former (HR=1.45, 95%CI 1.28, 1.65, p<.001) and daily smokers (HR=1.93, 95%CI 1.71, 2.17, p<.001) showed elevated disability pension risk compared to never smokers. Among women, daily smokers (HR=1.25, 95%CI 1.11, 1.40, <.001) had elevated risk. The age and smoking adjusted risk estimates for alcohol were elevated among abstainers (men HR=1.41, 95%CI 1.21, 1.65, p<.001; women HR=1.36, 95%CI 1.23, 1.52, p<.001) and heavy drinkers (men HR=1.30, 95%CI 1.18, 1.43, p<.001; women HR=1.34, 95%CI 1.04, 1.72, p=.026). Those being persistent smokers and binge drinkers had over three-fold disability risk compared to those who were binge drinkers but had only a few smoking years (men: HR=3.32, 95%CI 2.43, 4.54, p<.001; women: HR=4.05, 95%CI 2.05, 8.00, p<.001). Among men and women who were not binge drinkers, longer smoking duration was needed for elevated disability risk.

CONCLUSIONS

Both smoking and excess alcohol use significantly predict disability retirement. In order to extend working careers, more attention should be paid to health behaviors, in addition to working conditions.

Patients Undergoing Substance Abuse Treatment and Receiving Financial Assistance for a Physical Disability Respond Well to Contingency Management Treatment

Physical illness and disability are common in individuals with substance use disorders, but little is known about the impact of physical disability status on substance use treatment outcomes. This study examined the main and interactive effects of physical disability payment status on substance use treatment. Participants (N = 1,013) were enrolled in one of six prior randomized clinical trials comparing contingency management (CM) to standard care; 79 (7.8%) participants reported receiving disability payments, CM improved all three primary substance use outcomes: treatment retention, percent negative samples and longest duration of abstinence. There was no significant main effect of physical disability payment status on treatment outcomes; however, a significant treatment condition by physical disability status interaction effect emerged in terms of retention in treatment and duration of abstinence achieved. Patients who were receiving physical disability payments responded particularly well to CM, and their time in treatment and durations of drug and alcohol abstinence increased even more markedly with CM than did that of their counterparts who were not receiving physical disability assistance. These findings suggest an objectively defined cohort of patients receiving substance use treatment who respond particularly well to CM.

Medical benefits in young adulthood: a population-based longitudinal study of health behaviour and mental health in adolescence and later receipt of medical benefits

OBJECTIVES

To examine the extent to which smoking, alcohol, physical activity and mental health problems in 15-16-year-olds are associated with receipt of medical benefits in young adulthood, after adjustment for confounders.

DESIGN

Prospective population-based cohort survey linked to national registers.

PARTICIPANTS

In the 'Youth studies' from the Norwegian Institute of Public Health, 15 966 10th graders in 6 Norwegian counties answered a health behaviour and mental health questionnaire; 88% were linked to National Insurance Administration Registers (FD-Trygd).

OUTCOME MEASURE

Time to receipt of medical benefits, based on FD-Trygd. Follow-up was from age 18 years until participants were aged 22-26 years.

METHOD

We performed Cox regression analyses to examine the extent to which variations in health behaviour and mental health problems during 10th grade were associated with receipt of medical benefits during follow-up.

RESULTS

Daily smoking at age 15-16 years was associated with a significant increase in hazard of receiving health benefits at follow-up compared with not smoking for boys, HR (95% CI) 1.56 (1.23 to 1.98), and for girls 1.47 (1.12 to 1.93). Physical activity was associated with a decrease in hazard compared with inactivity from 23% to 53% in boys and from 21% to 59% in girls, while use of alcohol showed a mixed pattern. The hazard for benefits use rose with increasing levels of emotional symptoms, peer problems, conduct problems and hyperactivity-inattention problems (Strengths and Difficulties Questionnaire) at 15-16 years among both genders.

CONCLUSIONS

Health behaviour and mental health problems in adolescence are independent risk factors for receipt of medical benefits in young adulthood.

Abstinence and current or former alcohol use as predictors of disability retirement in Finland

Aim: According to previous studies, abstinence from alcohol increases the risk of disability retirement (DR). We studied whether former alcohol users’ poor mental or physical health might have contributed to this result. Methods: Prospective population-based study of 3621 occupationally active Finns aged 30–55 years at baseline. Disability pension data for 2000−2011 was retrieved from national pension records. We examined medically certified disability retirement due to all causes and due to mental disorders among lifelong abstainers, former drinkers, those with an alcohol use disorder irrespective of consumption and current users, further classified according to weekly intake of alcohol. Chronic somatic diseases were evaluated in a clinical examination and common mental and alcohol use disorders using the Composite International Diagnostic Interview. Cox regression was used. Results: Neither lifelong abstinence nor alcohol consumption, even at hazardous levels, without alcohol use disorder was associated with disability retirement. Compared with light drinkers, former drinkers’ hazard ratio for DR due to mental disorders was 2.67 (95% CI 1.39−5.13), allowing for somatic and mental morbidity, physical and psychosocial workload, health behaviour and socio-demographic factors. The respective hazard ratio of DR due to all causes for those with alcohol use disorder was 2.17 (1.49−3.16) and of DR due to mental disorders 4.04 (2.02 to 8.06). Conclusions: Lifelong abstinence did not predict disability retirement. Former drinkers and people with alcohol use disorders were at a multi-fold risk of work disability due to mental disorders compared with light drinkers, thus it is important to support their work ability.

IQ and level of alcohol consumption—findings from a national survey of Swedish conscripts

BACKGROUND

Studies of the association between IQ and alcohol consumption have shown conflicting results. The aim of this study was to investigate the association between IQ test results and alcohol consumption, measured as both total alcohol intake and pattern of alcohol use.

METHODS

The study population consists of 49,321 Swedish males born 1949 to 1951 who were conscripted for Swedish military service 1969 to 1970. IQ test results were available from tests performed at conscription. Questionnaires performed at conscription provided data on total alcohol intake (consumed grams of alcohol/wk) and pattern of drinking. Multinomial and binomial logistic regressions were performed on the cross-sectional data to estimate odds ratios (ORs) with 95% confidence intervals (CIs). Adjustments were made for socioeconomic position as a child, psychiatric symptoms and emotional stability, and father's alcohol habits.

RESULTS

We found an increased OR of 1.20 (1.17 to 1.23) for every step decrease on the stanine scale to be a high consumer versus a light consumer of alcohol. For binge drinking, an increased OR of 1.09 (95% CI = 1.08 to 1.11) was estimated for every step decrease on the stanine scale. Adjustment for confounders attenuated the associations. Also, IQ in adolescence was found to be inversely associated with moderate/high alcohol consumption measured in middle age.

CONCLUSIONS

We found that lower results on IQ tests are associated with higher consumption of alcohol measured in terms of both total alcohol intake and binge drinking in Swedish adolescent men.

Cannabis use in adolescence and risk of future disability pension: a 39-year longitudinal cohort study

AIMS

This study aimed at examining a possible association between cannabis use in adolescence and future disability pension (DP). DP can be granted to any person in Sweden aged 16-65 years if working capacity is judged to be permanently reduced due to long-standing illness or injury.

METHODS

Data were obtained from a longitudinal cohort study comprising 49,321 Swedish men born in 1949-1951 who were conscripted to compulsory military service aged 18-20 years. Data on DP was collected from national registers.

RESULTS

Results showed that individuals who used cannabis in adolescence had considerably higher rates of disability pension throughout the follow-up until 59 years of age. In Cox proportional-hazards regression analyses, adjustment for covariates (social background, mental health, physical fitness, risky alcohol use, tobacco smoking and illicit drug use) attenuated the associations. However, when all covariates where entered simultaneously, about a 30% increased hazard ratio of DP from 40 to 59 years of age still remained in the group reporting cannabis use more than 50 times.

CONCLUSIONS

This study shows that heavy cannabis use in late adolescence was associated with an increased relative risk of labor market exclusion through disability pension.

Non-employment histories of middle-aged men and women who died from alcohol-related causes: a longitudinal retrospective study

Background

Long-term patterning of non-employment among problem drinkers is poorly understood. We determined the level and timing of non-employment, and the relative contribution of various types of non-employment among middle-aged persons who died of alcohol-related causes.

Methods

We conducted a longitudinal retrospective register-based study of Finnish men and women aged 45–64 years who died of alcohol-related causes (n = 15 552) or other causes (n = 39 166) in the period 2000–07, or who survived (n = 204 422) until the end of 2007. We traced back the number of days in employment and non-employment for up to 17 years before death or before the end of the study period for the survivors.

Results

The majority (≥56%) of persons who died of alcohol-related causes were in employment up to ten years before death. Over the 17-year period before death, those who died of alcohol-related causes were in employment on average two years less (mean 6.3 years, 95%CI 6.2–6.4) than those dying of other causes (8.2, 8.1–8.3), and five years less than survivors (11.6, 11.5–11.7), when sex and age were adjusted for. The relative role of various types of non-employment differed markedly across the two mortality groups. Among those who died of alcohol-related causes, unemployment accounted for 54% of the total burden of non-employment, in comparison with 29% among those who died of other causes. In contrast, disability pension accounted for 41% of the total burden of non-employment among those who died of alcohol-related causes, but 65% among those who died of other causes.

Conclusions

The results indicate the feasibility of preventing movement out of employment among middle-aged men and women with severe alcohol-related harm, provided that they are identified early on during their working careers and offered effective interventions.

Alcohol screening and brief intervention for adolescents: the how, what and where of reducing alcohol consumption and related harm among young people

AIM

The aim of the study was to explore the evidence base on alcohol screening and brief intervention for adolescents to determine age appropriate screening tools, effective brief interventions and appropriate locations to undertake these activities.

METHODS

A review of existing reviews (2003-2013) and a systematic review of recent research not included in earlier reviews.

RESULTS

The CRAFFT and AUDIT tools are recommended for identification of 'at risk' adolescents. Motivational interventions delivered over one or more sessions and based in health care or educational settings are effective at reducing levels of consumption and alcohol-related harm.

CONCLUSION

Further research to develop age appropriate screening tools needs to be undertaken. Screening and brief intervention activity should be undertaken in settings where young people are likely to present; further assessment at such venues as paediatric emergency departments, sexual health clinics and youth offending teams should be evaluated. The use of electronic (web/smart-phone based) screening and intervention shows promise and should also be the focus of future research.

The effect of community-acquired bacteraemia on return to workforce, risk of sick leave, permanent disability pension and death: a Danish population-based cohort study

OBJECTIVES

Little is known about the prognosis of community-acquired bacteraemia (CAB) in workforce adults. We assessed return to workforce, risk for sick leave, disability pension and mortality within 1 year after CAB in workforce adults compared with blood culture-negative controls and population controls.

DESIGN

Population-based cohort study.

SETTING

North Denmark, 1996-2011.

PARTICIPANTS

We used population-based healthcare registries to identify all patients aged 20-58 years who had first-time blood cultures obtained within 48 h of medical hospital admission, and who were part of the workforce (450 bacteraemia exposed patients and 6936 culture-negative control patients). For each bacteraemia patient, we included up to 10 matched population controls.

PRIMARY AND SECONDARY OUTCOME MEASURES

Return to workforce, risk of sick leave, permanent disability pension and mortality within 1 year after bacteraemia. Regression analyses were used to compute adjusted relative risks (RRs) with 95% CIs.

RESULTS

One year after admission, 78% of patients with CAB, 85.7% of culture-negative controls and 96.8% of population controls were alive and in the workforce, and free from sick leave or disability pension. Compared with culture-negative controls, bacteraemia was associated with an increased risk for long-term sick leave (4-week duration, 40.2% vs 23.9%, adjusted RR, 1.51; CI 1.34 to 1.70) and an increased risk for mortality (30-day mortality, 4% vs 1.4%, adjusted RR, 2.34, CI 1.22 to 4.50; 1-year mortality, 8% vs 3.9%, adjusted RR, 1.73; CI 1.18 to 2.55). Bacteraemia patients had a risk for disability pension similar to culture-negative controls (2.7% vs 2.6%, adjusted RR, 0.99, CI 0.48 to 2.02) but greater than population controls (adjusted RR, 5.20; 95% CI 2.16 to 12.50).

CONCLUSIONS

CAB is associated with long duration of sick leave and considerable mortality in working-age adults when compared with blood culture-negative controls, and an increased 1-year risk for disability pension when compared with population controls.

Cognitive ability in late adolescence and disability pension in middle age: follow-up of a national cohort of Swedish males

Low cognitive ability in late adolescence has previously been shown to be associated with disability pension (DP) in young adulthood. However, most DP's are granted later in working life, and the mechanisms of the association are not fully understood. We aimed to investigate the association between cognitive ability in late adolescence and DP at ages 40-59, and investigate the role of individual and socioeconomic factors. Information on cognitive ability, health status, personality aspects and health behaviours at age 18-20 was obtained from the 1969-70 conscription cohort, comprising 49,321 Swedish men. Data on DP's 1991-2008 was obtained from the Longitudinal Database of Education, Income and Employment. Information on socioeconomic and work-related factors in childhood and adulthood was obtained from national sociodemographic databases. Hazard ratios for DP during follow-up were estimated by Cox proportional hazards models. We found a graded relationship between cognitive ability in late adolescence and DP in middle age. One step decrease on the nine-point stanine scale of cognitive ability was associated with a crude hazard ratio of 1.26 (95% CI 1.24-1.27). Socioeconomic and work-related circumstances in adulthood explained much of the association, but factors measured already in late adolescence also showed importance. The findings suggest an accumulation of risks over the life course. Although attenuated, the graded relationship remained after adjusting for all factors.

A prospective cohort study of disability pension due to mental diagnoses: the importance of health factors and behaviors

BACKGROUND

Previous studies have found associations between various health factors and behaviors and mental disorders. However, knowledge of such associations with disability pension (DP) due to mental diagnoses is scarce. Moreover, the influence of familial factors (genetics and family background) on the associations are mainly unknown. The aim of the study was to investigate associations between health factors and behaviors and future DP due to mental diagnoses in a twin cohort, accounting for familial confounding.

METHODS

A prospective cohort study of Swedish twins (N=28 613), including survey data and national register data on DP and other background factors was conducted. Cox proportional hazards regression models were used to calculate hazard ratios (HR) with 95% confidence intervals (CI) for the whole twin cohort, and for discordant twin pairs.

RESULTS

During follow-up 1998-2008 (median 10 years), 2.2% of the cohort was granted a DP with a mental diagnosis. In the fully adjusted analyses of the whole cohort, the associations of poor or moderate self-rated health (SRH), under- or overweight, former or current tobacco use, or being an abstainer from alcohol were significantly associated with risk of DP due to mental diagnoses. Analyses of discordant twin pairs confirmed all these associations, except for current tobacco use, being independent from familial confounding. Exclusion of individuals with current or previous depression or anxiety at baseline did not influence the associations found.

CONCLUSIONS

Poor or moderate SRH, under- or overweight, former tobacco use or being an abstainer from alcohol seem to be strong direct predictors of DP due to mental diagnoses, independently of several confounders of this study, including familial factors.

The Health Hazards of Marriage. A cohort study of work related disability within 12,500 Norwegian couples - the HUNT Study

AIMS

Work disability and sickness absence increase following partner's retirement, which similarities in spouses' health could explain. We therefore studied the risk of work disability within couples, taking account of baseline health, lifestyle and socioeconomic factors.

METHODS

A cohort of 12,511 couples from the HUNT Study (aged 20-67 years in HUNT2, 1995-1997) was linked to national registries, identifying all new cases of disability pension up until December 2007. Data were analysed with discrete time multilevel logistic regression and Cox regression models. Partners' disability pension was included as a time-varying covariate. Follow-up time was split to examine the association dependent of time. Analyses were adjusted for age only, adjusted for health, and for lifestyle and education along with health.

RESULTS

About 15% of an individual's propensity to receive a disability pension could be attributed couple similarity. There was an increased risk of work disability following the spouse's disability retirement [HR (hazard ratio) 1.43 (95% confidence interval 1.20-1.71) for men, HR 1.49 (95% confidence interval 1.28-1.74) for women]. The association was somewhat attenuated after adjustments for health, lifestyle and education.

CONCLUSION

There was a substantial clustering of disability pensions within couples, which cannot be explained by similarities in health, lifestyle and education. This suggests partners influence each other's work ability. From a clinical perspective, the family situation needs to be taken into account when addressing health promotion and work participation.
