The importance of age groups in estimates of alcohol-attributable mortality: impact on trends in Switzerland between 1997 and 2011

Effects of current alcohol use on brain volume among older adults in the Gothenburg H70 Birth Cohort study 2014-16

Brain gray- and white matter changes is well described in alcohol-dependent elderly subjects; however, the effect of lower levels of alcohol consumption on the brain is poorly understood. We investigated the impact of different amounts of weekly alcohol consumption on brain structure in a population-based sample of 70-year-olds living in Gothenburg, Sweden. Cross-sectional data from 676 participants from The Gothenburg H70 Birth Cohort Study 2014-16 were included. Current alcohol consumers were divided into seven groups based on self-reported weekly amounts of alcohol consumption in grams (g) (0-50 g/week, used as reference group, 51-100 g/week, 101-150 g/week, 151-200 g/week, 201-250 g/week, 251-300 g/week, and > 300 g/week). Subcortical volumes and cortical thickness were assessed on T1-weighted structural magnetic resonance images using FreeSurfer 5.3, and white matter integrity assessed on diffusion tensor images, using tract-based statistics in FSL. General linear models were carried out to estimate associations between alcohol consumption and gray- and white matter changes in the brain. Self-reported consumption above 250 g/week was associated with thinning in the bilateral superior frontal gyrus, the right precentral gyrus, and the right lateral occipital cortex, in addition to reduced fractional anisotropy (FA) and increased mean diffusivity (MD) diffusively spread in many tracts all over the brain. No changes were found in subcortical gray matter structures. These results suggest that there is a non-linear relationship between alcohol consumption and structural brain changes, in which loss of cortical thickness only occur in non-demented 70-year-olds who consume more than 250 g/week.

Methodological guidelines for the estimation of attributable mortality using a prevalence-based method: The STREAMS-P tool

BACKGROUND

There is evidence of strong links between exposure to different risk factors and life-threatening diseases. Assessing the burden of a risk factor on the population's mortality due to a given disease provides a clear picture of these links. The estimation of attributable mortality to a risk factor is the most widely used procedure for doing this. Although different methods are available to estimate attributable mortality, the prevalence-based methodology is the most frequent. The main objective of this paper is to develop guidelines and checklists to STrengthen the design and REporting of Attributable-Mortality Studies using a Prevalence-based method (STREAMS-P) and also to assess the quality of an already published study which uses this methodology.

METHODS

The design of the guideline and checklists has been done in two phases. A development phase, where we set recommendations based on the review of the literature; and a validation phase, where we validated our recommendations against other published studies that have estimated attributable mortality using a prevalence-based method.

RESULTS

We have developed and tested a guideline that includes the information required to perform a prevalence-based attributable mortality study to a given risk factor; a checklist of aspects that should be present when a report or a paper on attributable mortality is written or interpreted and a checklist of quality control criteria for reports or papers estimating attributable mortality.

CONCLUSION

To our knowledge, the STREAMS-P is the first set of criteria specifically created to assess the quality of such studies and it could be valuable for authors and readers interested in performing attributable mortality studies or interpreting their reliability.

Distinct health-related risk profiles among middle-aged and older adults with risky alcohol use from the Danish general population

BACKGROUND

Knowledge is lacking on distinct health-related risk profiles among the substantial group of middle-aged and older adults with risky alcohol use (AU). Such profiles could inform the planning of interventions and prevention.

AIMS

To 1) identify distinct health-related profiles based on different types of health-related functioning limitations and distress and 2) assess associations between these profiles and age, sex, and health-relevant behaviors (e.g., smoking).

METHODS

Cross-sectional nation-wide Danish health survey with n = 6630 adults aged 55-64 and n = 7605 aged 65-74 with at least risky AU (>84 g ethanol/week in women, >168 in men). Health-related risk profiles were identified with Latent Class Analysis (LCA). Multinomial regression was applied for the association between risk profiles and auxiliary variables.

RESULTS

A six-class LCA solution was found among 55-64 year-olds (classes: 'Normative' [61%], 'Distress' [6%], 'Mental health limitations [5%]', 'Pain-related distress [10%]', 'Broad limitations and pain distress [7%]', 'High overall burden' [11%]) and a five-class solution among 65-74 year-olds. Most classes were comparable across age groups. The 'Distress'-class characterized by pain-distress, tiredness-distress, and sleep-related distress (6%) only showed in the younger group. In both age groups, auxiliary covariates (high-risk AU, possible alcohol use disorder, weekly smoking) were positively associated with problematic profile membership (vs. normative class membership).

CONCLUSION

Middle-aged and older adults with risky AU have distinct health-related profiles relevant for the form and content of prevention and interventions. Despite their distinct features, almost all problematic health profiles warrant careful attention regarding high-risk AU and probable alcohol use disorder.

Trends and differences in alcohol-related mortality rates by gender and by prefectures in Japan between 1995 and 2016

BACKGROUND

This study aimed to identify increases in 100 % alcohol-related death (ARD) and any differences among prefectures between 1995-2016.

METHODS

Data from the national death registry on 100 % ARDs between 1995-2016 were extracted. Age-standardized mortality rate (ASMR) of 100 % ARD by year, gender, and gender ratio were calculated. After dividing the period into 1995-2005 and 2006-2016, the ASMRs of 100 % ARDs were calculated by prefecture. Additionally, based on geographical area, municipality size, or annual alcohol sales per adult in each prefecture, prefectures were divided into groups and analysed.

RESULTS

In total, 95,455 deaths were caused by 100 % ARD from 1995-2016. Men's ASMRs of 100 % ARD markedly increased from 4.0 per 100,000 in 1995 to 5.2 between 2010 and 2013, and gradually declined to 5.0 in 2016. Women's ASMRs increased steadily from 0.3 in 1995 to 0.8 in 2016. The gender ratio of ASMRs decreased from 13.3 in 1995 to 6.3 in 2016. The ASMR of one prefecture, which had reduced alcohol tax rates, was higher for both genders. Both men's and women's ASMRs were higher in the prefectures that had higher alcohol sales (6.3 [5.0-7.7] and 0.8 [0.6-1.1], respectively) compared to the prefectures that had lower alcohol sales (4.3 [4.0-4.7] p < 0.001 and 0.6 [0.5-0.6] p = 0.045, respectively).

CONCLUSIONS

The ASMR of 100 % ARD remained high for men and increased for women, and prefecture-level higher alcohol sales and lower tax rates correlated with the higher mortality rate. Increasing prices and taxes and reducing alcohol sales may contribute to a decrease in alcohol-related mortality.

Mortality of treatment-seeking men and women with alcohol, opioid or other substance use disorders - A register-based follow-up study

BACKGROUND

Alcohol (AUD), opioid (OUD) and other substance use disorders (SUD) are associated with an increased risk of premature death. The aim of this register-based follow-up study was to compare the risk of death between individuals who had sought treatment for AUDs, OUDs and other SUDs in Finland.

DESIGN, SETTING, PARTICIPANTS

Data included 10,888 individuals who had sought help from three clinics at some point between 1990 and 2009. Treatment data were linked to national register data concerning education, hospitalizations and death by the year 2018.

MEASUREMENTS

Individuals were categorized into four groups: only alcohol (AUD-only), all OUDs (OUD-all), other or multiple SUDs (SUD-other) and outpatients without substance-related diagnoses or hospitalizations (SU-NAS); in mortality analyses, those who had started in opioid substitution treatment (OST) were analyzed separately. COX regression analyses were used to calculate the risk of death by the year 2018 or up to 15 years after seeking treatment.

RESULTS

Among the 10,888 treatment-seeking individuals the cumulative mortality rates during 1-, 5- and 15-year follow-up were 2.5% (n = 271), 10.9% (n = 1191) and 28.4% (n = 3096), respectively. The mean age at death varied according to substance of use (55.0 years for AUD-only, 35.8 OUD-all, 45.8 SUD-other and 55.6 SU-NAS). The patients who had started in OST had a lower risk of death compared to the other groups, as did the SU-NAS group that likely included individuals with a less severe course of AUDs/SUDs. There were no differences between the AUD-only, OUD-other and SUD-other groups for the risk of death during the 15-year follow-up period when gender and year of birth were included as covariates.

CONCLUSIONS

The mortality rates were very high; however, most of the deaths occurred several years after seeking treatment. The lower mortality amongst the patients who had initiated OST solidifies previous knowledge on the benefits of OST and efforts should be made to improve access to treatment. These results show that treatment plays a role in lowering the risk of death among individuals with AUDs/SUDs.

DSM-5 alcohol use disorder features among treatment-seeking older adults

Abstract. Background: The number of older adults with alcohol use disorder (AUD) is expected to rise. Adapted treatments for this group are lacking and information on AUD features in treatment seeking older adults is scarce. The international multicenter randomized-controlled clinical trial “ELDERLY-Study” with few exclusion criteria was conducted to investigate two outpatient AUD-treatments for adults aged 60+ with DSM-5 AUD. Aims: To add to 1) basic methodological information on the ELDERLY-Study by providing information on AUD features in ELDERLY-participants taking into account country and gender, and 2) knowledge on AUD features in older adults seeking outpatient treatment. Methods: baseline data from the German and Danish ELDERLY-sites (n=544) were used. AUD diagnoses were obtained with the Mini International Neuropsychiatric Interview, alcohol use information with Form 90. Results: Lost control, desired control, mental/physical problem, and craving were the most prevalent (> 70 %) AUD-symptoms. 54.9 % reported severe DSM-5 AUD (moderate: 28.2 %, mild: 16.9 %). Mean daily alcohol use was 6.3 drinks at 12 grams ethanol each. 93.9 % reported binging. More intense alcohol use was associated with greater AUD-severity and male gender. Country effects showed for alcohol use and AUD-severity. Conclusion: European ELDERLY-participants presented typical dependence symptoms, a wide range of severity, and intense alcohol use. This may underline the clinical significance of AUD in treatment-seeking seniors.

Comparison of different approaches for estimating age-specific alcohol-attributable mortality: The cases of France and Finland

Background

Accurate estimates of the impact of alcohol on overall and age-specific mortality are crucial for formulating health policies. However, different approaches to estimating alcohol-attributable mortality provide different results, and a detailed comparison of age-specific estimates is missing.

Methods

Using data on cause of death, alcohol consumption, and relative risks of mortality at different consumption levels, we compare eight estimates of sex- and age-specific alcohol-attributable mortality in France (2010) and Finland (2013): five estimates using cause-of-death approaches (with one accounting for contributory causes), and three estimates using attributable fraction (AF) approaches.

Results

AF-related approaches and the approach based on alcohol-related underlying and contributory causes of death provided estimates of alcohol-attributable mortality that were twice as high as the estimates found using underlying cause-of-death approaches in both countries and sexes. The differences across the methods were greatest among older age groups An inverse U-shape in age-specific alcohol-attributable mortality (peaking at around age 65) was observed for cause-of-death approaches, with this shape being more pronounced in Finland. AF-related approaches resulted in different estimates at older ages: i.e., mortality was found to increase with age in France; whereas in Finland mortality estimates depended on the underlying assumptions regarding the effects of alcohol consumption on cardiovascular mortality.

Conclusions

While the most detailed approaches (i.e., the AF-related approach and the approach that includes underlying and contributory causes) are theoretically able to provide more accurate estimates of alcohol-attributable mortality, they–especially the AF approaches- depend heavily on data availability and quality. To enhance the reliability of alcohol-attributable mortality estimates, data quality for older age groups needs to be improved.
