The effects of exceeding low-risk drinking thresholds on self-rated health and all-cause mortality in older adults: the Tromsø study 1994-2020

BACKGROUND

Based on findings of increasing alcohol consumption in older adults, it is important to clarify the health consequences. Using data from the Tromsø study, we aimed to investigate the relationship between different levels of alcohol consumption in old adulthood and self-rated health trajectories and all-cause mortality.

METHODS

This is an epidemiological study utilizing repeated measures from the Tromsø study cohort. It allows follow-up of participants from 1994 to 2020. A total of 24,590 observations of alcohol consumption were made in older adults aged 60-99 (53% women).

PRIMARY OUTCOME MEASURES

Self-rated health (SRH) and all-cause mortality. SRH was reported when attending the Tromsø study. Time of death was retrieved from the Norwegian Cause of Death Registry. The follow-up time extended from the age of study entry to the age of death or end of follow-up on November 25, 2020.

PREDICTOR

Average weekly alcohol consumption (non-drinker, < 100 g/week, ≥100 g/week). We fitted two-level logistic random effects models to examine how alcohol consumption was related to SRH, and Cox proportional hazards models to examine its relation to all-cause mortality. Both models were stratified by sex and adjusted for sociodemographic factors, pathology, biometrics, smoking and physical activity. In addition, all the confounders were examined for whether they moderate the relationship between alcohol and the health-related outcomes through interaction analyses.

RESULTS

We found that women who consumed ≥100 g/week had better SRH than those who consumed < 100 g/week; OR 1.85 (1.46-2.34). This pattern was not found in men OR 1.18 (0.99-1.42). We identified an equal mortality risk in both women and men who exceeded 100 g/week compared with those who consumed less than 100 g/week; HR 0.95 (0.73-1.22) and HR 0.89 (0.77-1.03), respectively.

CONCLUSIONS

There was no clear evidence of an independent negative effect on either self-rated health trajectories or all-cause mortality for exceeding an average of 100 g/week compared to lower drinking levels in this study with up to 25 years follow-up. However, some sex-specific risk factors in combination with the highest level of alcohol consumption led to adverse effects on self-rated health. In men it was the use of sleeping pills or tranquilisers and ≥ 20 years of smoking, in women it was physical illness and older age.

35 Years of health surveys in Denmark: a backbone of public health practice and research

Denmark has a 35-year history of monitoring health status in the general population through health surveys. In this commentary, we outline the development of health surveys in Denmark from the beginning in 1987 to the present time. We describe how the current systematic framework for the Danish National Health Survey (DNHS) developed. We discuss the methodological basis for the DNHS and describe its application in public health practice and research. Over the years, the DNHS has become an important part of the Danish public health environment. Challenges for the DNHS in the future are to adapt to new trends in public health and at the same time to be able to monitor important changes consistently over time.

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.

Sex differences in at-risk drinking and associated factors-a cross-sectional study of 8,616 community-dwelling adults 60 years and older: the Tromsø study, 2015-16

BACKGROUND

Alcohol consumption among older adults is on the rise, which may be an increasing public health concern. The proportion of older adults who drink above defined low-risk drinking limits, associated characteristics and the sex distribution of at-risk drinking vary across countries. The aims of this study were to (i) estimate the prevalence of at-risk drinking among older adults in Norway, (ii) investigate factors associated with at-risk drinking, and (iii) examine sex differences in alcohol consumption in the context of sociodemographic and selected health characteristics.

METHOD

A cross-sectional study based on Tromsø 7 (2015-16), an ongoing population-based cohort survey. Data were retrieved from participants aged 60 and older (60-99 years) who answered questions about alcohol consumption (n = 8,616). Sex-stratified logistic regressions were used to assess the association between three at-risk drinking outcome variables, and sociodemographic and selected health characteristics. The outcome variables were operationalized using the Alcohol Use Disorders Identification Test (AUDIT), and Alcohol Consumption Questions (AUDIT-C), i.e. - cut off for at risk drinking, drinking any 6+ in the past year, and any alcohol problems.

RESULTS

The overall prevalence of at-risk drinking among those aged 60-99 years was equal in women and men; 44% and 46%, respectively. At-risk drinking was strongly associated with a higher level of education, with OR 2.65 (CI 2.28-3.10) in women and OR 1.73 (CI 1.48-2.04) in men.

CONCLUSIONS

Almost half of older adults in Norway exceeded sex- and older adult-specific at-risk drinking thresholds. Our findings suggest some differences in factors associated with at-risk drinking between women and men. Explicitly, at-risk drinking was associated with very good health, living with a spouse or partner, and having adequate social support in women, while it was associated with the use of sleeping pills in men. Our findings suggest that women exceed at-risk drinking thresholds with better health, while men exceed at-risk drinking thresholds regardless of good or poor health.

Association between negative life events and morbidity in homeless seeking treatment for substance abuse in Greenland

INTRODUCTION

The aim of the investigation was to describe the association between negative life events on morbidity in homeless seeking treatment for substance abuse in Greenland.

METHODS

Cross sectional study on register data comparing homeless and individuals in secure housing initiating alcohol or substance abuse treatment in Greenland between 1 January 2017 and 14 December 2019, (N = 950). Results: Homeless were socio-economically disadvantaged compared to treatment seekers in secure housing. They had a heavier burden of psychiatric morbidity and suffered more negative life experiences. Controlled for having experienced abuse, most morbidity measures' predictive value was slightly less pronounced with psychiatric morbidity as an exception.

CONCLUSION

The results indicate that both the morbidity and most analyzed negative life events are associated with being homeless and are mutually linked.

History of healthcare use and disease burden in older adults with different levels of alcohol use. A register-based cohort study

BACKGROUND

Only a minority of individuals with problematic alcohol use ever seek alcohol treatment. Knowledge of general help-seeking behavior in the healthcare system can identify possibilities for prevention and intervention.

METHOD

The current study describes healthcare use, burden of disease, and prior morbidities over a 15-year period by current alcohol use behavior among Danish adults aged 60-70. The Danish National Health Survey 2013 and the baseline assessment of the Elderly Study (2014-2016) were linked to Danish national registers to collect annual information on healthcare use and morbidity for the 15 years prior to inclusion. Participants from the 3 largest Danish municipalities were divided into 4 groups with varying drinking patterns and no recent treatment [12-month abstinent (n = 691), low-risk drinkers (n = 1978), moderate-risk drinkers (n = 602), and high-risk drinkers (n = 467)], and a group of treatment-seeking individuals with a 12-month DSM-5 alcohol use disorder (AUD; n=262). Negative binomial regression models were utilized to compare rates of healthcare use and logistic regressions were used to compare odds of diagnoses.

RESULTS

Low-, moderate-, and high-risk drinkers had similar rates of past healthcare utilization (low-risk mean yearly number of contacts for primary care 7.50 (yearly range 6.25-8.45), outpatient care 0.80 (0.41-1.32) and inpatient care 0.13 (0.10-0.21)). Higher rates were observed for both the 12-month abstinent group (adjusted RR = 1.16-1.26) and the group with AUD (ARR = 1.40-1.60) compared to the group with low-risk alcohol consumption. Individuals with AUD had higher odds of previous liver disease (adjusted OR = 6.30), ulcer disease (AOR = 2.83), and peripheral vascular disease (AOR 2.71). Twelve-month abstinence was associated with higher odds of diabetes (AOR = 1.97) and ulcer disease (AOR = 2.10).

CONCLUSIONS

Looking back in time, we found that older adults had regular healthcare contacts, with those who received treatment for AUD having had the highest contact frequency and prevalence of alcohol-related diseases. Thus, healthcare settings are suitable locations for efforts at AUD prevention and intervention.
