Alcohol consumption in later life and reaching longevity: the Netherlands Cohort Study

The Impact of Social Vulnerability on Alcohol Consumption and Mortality: A 20-year Age, Sex-stratified Analysis from the Taiwan Longitudinal Study of Aging

OBJECTIVE

This study aimed to use the Social Vulnerability Index (SVI) to encapsulate the complex and multidimensional nature of social determinants and their influence on alcohol intake and mortality in middle-aged and older individuals.

DESIGN

Cohort study.

SETTING AND PARTICIPANTS

Data were obtained from the Taiwan Longitudinal Study on Aging (TLSA), with 3945 study participants aged 50 years and older.

METHODS

The TLSA questionnaire defined SVI (51 items including living conditions, social support, socially oriented activities of daily living, social engagement and leisure, empowerment of life, satisfaction about life, and socioeconomic status) and alcohol intake (behavior as well as type and frequency of alcohol intake). Multivariate Cox proportional hazard models were used to estimate the association between alcohol intake and mortality, stratified by sex and SVI groups.

RESULTS

Men with high social vulnerability and high alcohol intake exhibit an elevated mortality risk [adjusted hazard ratio (aHR), 1.51; 95% CI, 1.01-2.24], whereas notably, women in similar social circumstances but with moderate alcohol intake face a quintupled mortality risk (>35 g/wk; aHR, 5.67; 95% CI, 2.37-13.61). The impact of alcohol and social vulnerability on mortality was more pronounced in men younger than 65. Among them, those with high social vulnerability and moderate (35-140 g/wk; aHR, 2.83; 95% CI, 1.50-5.36) to high (>140 g/wk; aHR, 2.24; 95% CI, 1.15-4.35) alcohol intake was associated with an increased risk of mortality.

CONCLUSIONS AND IMPLICATIONS

Various factors throughout the life course of both men and women significantly impact the risk of all-cause mortality due to alcohol intake, underscoring the importance of social vulnerability as a determinant of both alcohol intake behavior and mortality risk.

Mid-life alcohol consumption and survival to age 90 in men: The Tromsø Study 1979-1980 with follow-up to 2019

AIMS

The Tromsø Study 1979-1980 collected information on alcohol (beer, wine and spirits) consumption frequency and inebriation frequency, and the oldest male participants (aged 50-54 years) were followed for all-cause mortality. This study aimed to identify the impact of habitual alcohol consumption in mid-life on reaching up to 90 years of age.

RESULTS

Among the study sample of 778, a total of 120 (15.4%) men reached the age of 90. The most common reported alcohol consumption frequency was 'never or a few times a year', and 18.9% of those in this group reached 90 compared with 11.9% of those who reported a more frequent beer consumption. Fifty per cent survival in these groups was 80.5 and 76.9 years, respectively. The pattern was similar for spirits consumption and for inebriation but not for wine consumption. Number of deaths increased gradually with increasing beer and spirits consumption frequency and with inebriation frequency. We observed no J-shape or pattern that revealed a beneficial influence of light alcohol consumption. Daily smoking, physical inactivity, marital status, blood pressure and total cholesterol reduced the contribution of alcohol consumption to a small degree.

CONCLUSIONS

This study shows that all beer and spirits consumption frequencies in mid-life affect later life and total lifespan. Refraining from alcohol consumption or drinking only a few times a year increases one's chances of living longer, and the chance of reaching 90 years of age is 1.6-fold higher than in those with more frequent alcohol consumption.

Intrinsic and environmental basis of aging: A narrative review

Longevity has been a topic of interest since the beginnings of humanity, yet its aetiology and precise mechanisms remain to be elucidated. Aging is currently viewed as a physiological phenomenon characterized by the gradual degeneration of organic physiology and morphology due to the passage of time where both external and internal stimuli intervene. The influence of intrinsic factors, such as progressive telomere shortening, genome instability due to mutation buildup, the direct or indirect actions of age-related genes, and marked changes in epigenetic, metabolic, and mitochondrial patterns constitute a big part of its underlying endogenous mechanisms. On the other hand, several psychosocial and demographic factors, such as diet, physical activity, smoking, and drinking habits, may have an even more significant impact on shaping the aging process. Consequentially, implementing dietary and exercise patterns has been proposed as the most viable alternative strategy for attenuating the most typical degenerative aging changes, thus increasing the likelihood of prolonging lifespan and achieving successful aging.

A mechanistic perspective on the health promoting effects of alcohol - A focus on epigenetics modification

While the detrimental effects of binge drinking are well recognized, low-to-moderate alcohol consumption may be beneficial to health, although the underlying mechanism(s) remains elusive. In this opinion article, we will examine the effects of low dose alcohol consumption from the perspective of epigenetic modulation. Biochemically, alcohol is metabolized into acetate and subsequently to acetyl-coA, which can modulate histone acetylation levels. While elevated levels of acetyl-CoA are detrimental for longevity, we argue that diminished acetyl-CoA also negatively affects fatty acid biosynthesis and histone acetylation, which play a critical role in gene expression and, ultimately, health span. Since mitochondrial function and glucose metabolism, which provide the main source of nucleocytoplasmic acetyl-CoA, are compromised with age, alcohol-derived acetate could be an alternative source of acetyl-CoA to compensate. Hence, the health benefits of low ethanol consumption may be more pronounced after midlife, since mitochondrial function and/or glucose metabolism are diminished in this phase of the life course. Indeed, various clinical alcohol consumption studies concur with this notion, and have shown that a low dose of regular alcohol intake after midlife brings about various health and survival benefits. The requirement for regular alcohol intake may also reflect the transient nature of ethanol-induced histone acetylation. Conversely, ethanol may also stimulate carcinogenesis by inhibiting DNA methylation, as it was shown to reduce various pathways leading to DNA and histone methylation. However, unlike acetylation, where ethanol directly increases the substrate for acetylation, this effect was only observed in the high alcohol exposure cohort. While alcohol-derived acetate may be beneficial for health after midlife, various detrimental effects of alcohol consumption remain, and hence, we do not advocate excessive drinking to increase acetate. This opinion article establishes a possible role of ethanol-derived acetate in achieving homeostasis and sustaining an organism's health span.

Association of Lifestyle Behaviors With Hearing Loss: The UK Biobank Cohort Study

OBJECTIVE

To examine the combined association of five healthy lifestyle behaviors with hearing loss (HL) in the UK Biobank cohort, established between 2006 and 2010 in the United Kingdom.

METHODS

This longitudinal analysis included 61,958 participants aged 40 to 70 years from April 2007 to December 2016. The healthy behaviors examined were: never smoking, high level of physical activity, high diet quality, moderate alcohol intake, and optimal sleep. Hearing loss was self-reported at baseline and in any physical exam during the follow-up.

RESULTS

Over a median follow-up of 3.9±2.5 years, 3072 (5.0%) participants reported incident HL. After adjustment for potential confounders, including age, social factors, exposure to high-intensity noise, ototoxic medication, and comorbidity, the HRs of HL associated with having 1, 2, 3, and 4 to 5 vs 0 behaviors were: 0.85 (95% CI, 0.75 to 0.96), 0.85 (95% CI, 0.75 to 0.96), 0.82 (95% CI, 0.71 to 0.94), and 0.80 (95% CI, 0.67 to 0.97), respectively (P for trend, 0.02). We estimated that the population attributable risk percent for not adhering to any five low-risk lifestyle behaviors was 15.6%.

CONCLUSION

In this large study, an increasing number of healthy behaviors was associated with decreased risk of HL.

Associations between patterns of modifiable risk factors in mid-life to late life and longevity: 36 year prospective cohort study

Objective

To examine the associations between patterns of mid-life to late life modifiable risk factors and longevity.

Design

Prospective cohort study.

Setting

Data collected from the Nurses' Health Study starting in 1984 and the Health Professionals Follow-up Study starting in 1986.

Participants

85 346 participants from the Nurses' Health Study and the Health Professionals Follow-up Study.

Main outcome measures

Death from any cause by 31 October 2020 for the Nurses' Health Study and Health Professionals Follow-up Study. Risk factors investigated were body mass index, physical activity, alcohol intake, smoking status, and quality of diet. Trajectories of each risk factor and trajectories of changes in the risk factor were identified from baseline with smoothing mixture models, and the joint group memberships of participants was used to most efficiently capture patterns of the factor over time. For each risk factor, three trajectories (patterns with high, medium, and low values) and three trajectories of change in the risk factor (patterns with increase, no change, and decrease in the factor from baseline) were assumed, giving nine joint patterns: high-stable, high-increase, high-decrease, medium-stable, medium-increase, medium-decrease, low-stable, low-increase, and low-decrease. Associations between patterns of modifiable risk factors and longevity (age at death ≥85 years) and life expectancy were examined with logistic regression and accelerated failure time models, respectively.

Results

The analysis included 85 346 participants, with 46 042 participants achieving longevity and 25 322 participants achieving healthy longevity (those who did not have a diagnosis of cardiovascular disease, type 2 diabetes, or cancer). Mean age at baseline was 56 years (standard deviation 5 years). Maximum longevity was achieved in participants with a low-stable pattern for body mass index (compared with a medium-stable pattern, odds ratio of longevity of 1.05, 95% confidence interval 1.00 to 1.10); those with a medium-increase pattern for physical activity (compared with a medium-stable pattern, odds ratio 1.08, 1.01 to 1.15); those with a medium-stable pattern for alcohol intake (high-increase v medium-stable pattern, odds ratio 0.83, 0.74 to 0.93); those who never smoked (low-stable v medium-stable pattern, odds ratio 3.09, 2.84 to 3.37); and those who with a high-increase pattern for quality of diet (compared with a medium-stable pattern, odds ratio 1.09, 1.01 to 1.18). The associations between each factor and life expectancy and healthy longevity (no diagnosis of cardiovascular disease, type 2 diabetes, or cancer) were similar to those for longevity.

Conclusions

During mid-life and late life, maximum longevity was achieved in participants who maintained a normal body mass index, never smoked, ate a healthy diet, and had physical activity levels and alcohol consumption that met public health recommendations.

Applying Geriatric Principles to Hazardous Drinking in Older Adults

Older adults continue to drink as they age. Aging changes alcohol kinetics just as with any other drug. Older adults have increased sensitivity to acute alcohol intake that accounts for the increased risk of falls, traffic accidents, and other injury. The Annual Medicare Wellness Exam is an excellent opportunity to introduce screening for unsafe drinking along with accumulated risks and deficits of aging. Older adults have responded well to brief interventions for unhealthy drinking. In the presence of alcohol use disorder or serious comorbidity including psychiatric illness, referral to specialized multidisciplinary care can be lifesaving.

Older patients' perspectives toward lifestyle-related secondary cardiovascular prevention after a hospital admission-a qualitative study

BACKGROUND

lifestyle-related secondary prevention reduces cardiac events and is recommended irrespective of age. However, motivation may be influenced by age and disease progression.

OBJECTIVE

to explore older cardiac patients' perspectives toward lifestyle-related secondary prevention after a hospital admission.

METHODS

a generic qualitative design was used. Semi-structured interviews were performed with cardiac patients ≥ 70 years within 3 months after a hospital admission. The interview guide was based on the Attitudes, Social influence and self-Efficacy (ASE) model. All interviews were analysed using thematic analysis.

RESULTS

eight themes emerged which were linked to the determinants of the ASE-model. The three themes (i) Perspectives are determined by general health and habits, (ii) feeling the threat as a motivator and (iii) balancing between health benefits and quality of life (QoL), were linked to attitude. Regarding social influence, the themes (iv) feeling both encouraged and hindered by family members, and (v) the healthcare professional says so, were identified. For the self-efficacy determinant, (vi) experiences from previous lifestyle changes, (vii) integrating advice in daily life and (viii) feeling limited by functional impairments, emerged as themes.

CONCLUSION

most older cardiac patients made no lifestyle modifications after the last hospital admission and balanced possible benefits against their QoL. Functional impairments frequently limit implementation, in particular of physical activity. Patients' preferences and patient-centred outcomes focusing on QoL and functional independence may be the starting point when healthcare professionals discuss lifestyle modification in older patients. The involvement of family members may help patients to integrate lifestyle-related secondary prevention in daily life.

The association of alcohol use with all-cause and cardiovascular disease-related hospitalizations or death in older, high-risk Veterans

BACKGROUND

The prevalence of alcohol misuse among older adults has grown dramatically in the past decade, yet little is known about the association of alcohol misuse with hospitalization and death in this patient population.

METHODS

We examined the association between alcohol use (measured by a screening instrument in primary care) and rates of all-cause and cardiovascular disease (CVD)-related 6-month hospitalization or death via electronic health records (EHRs) in a nationally representative sample of older, high-risk Veterans. Models were adjusted for sociodemographic and clinical characteristics, including frailty and comorbid conditions.

RESULTS

The all-cause hospitalization or death rate at 6 months was 14.9%, and the CVD-related hospitalization or death rate was 1.8%. In adjusted analyses, all-cause hospitalization or death was higher in older Veterans who were nondrinkers or harmful use drinkers compared to moderate use drinkers, but CVD-related hospitalization or death was similar in all categories of drinking.

CONCLUSIONS

These findings suggest that the complex association between alcohol and all-cause acute healthcare utilization found in the broader population is similar in older, high-risk Veteran patients. These findings do not support an association between alcohol consumption and CVD-specific hospitalizations.

Alcohol and public mental health for older people: 20 years of UK policy change

Purpose

The purpose of this paper is to detail developments in UK alcohol policy for older people over the past 20 years, based on evidence for a growing public health problem with alcohol misuse in older people.

Design/methodology/approach

A literature search was carried out using health and social care databases, including grey literature.

Findings

There has been considerable progress in areas such as screening and brief intervention, low-risk drinking and service provision for integrated care in older people with dual diagnosis.

Research limitations/implications

There remains a dearth of research and policy for older people with alcohol misuse and dual diagnosis prior to 2011. Although there remains limited empirical evidence for public health interventions to improve health outcomes from alcohol-related harm, improvements in population health from implementation of recent policy changes and intervention programmes remains to be seen.

Practical implications

This review has implications for best practice in the provision of integrated care to reduce harm and improve health and social outcomes in older people with alcohol misuse and dual diagnosis.

Originality/value

This review draws together a large area of research and policy on alcohol misuse in older people that has the potential to improve public mental health for older people who are at risk of alcohol-related harm.

The environment as a determinant of successful aging or frailty

The number of elderly persons is rising rapidly, and healthspan is a key factor in determining the well-being of individuals and the sustainability of national health systems. Environmental health is crucial for a "successful aging". Complex relationships between environmental factors and non-communicable diseases play a major role, causing or accelerating disabilities. Besides genetic factors, aging results from the concurrence of several environmental factors starting from early (i.e. in utero) life, able to increase susceptibility to diseases in adulthood, and to promote frailty in the elderly. In aged people, an unhealthy environment contributes to a fast and early decline and increases vulnerability. Exposure to pollutants facilitates the onset and progression of cardiovascular, respiratory, metabolic and neurologic diseases through direct effects and epigenetic mechanisms negatively affecting biological age. Healthy diet, healthy environment and constant physical activity could counteract, at least in part, the negative effects of environmental stressors. Almost all environmental factors generating detrimental effects on aging are modifiable, with relevant implications in terms of primary prevention measures potentially leading to decreased frailty, to an increase in the number of years lived without diseases or disability, and to a significant reduction in health expenditure.
