The health-related effects of alcohol use in older persons: a systematic review

The association between alcohol consumption and all-cause mortality: An umbrella review of systematic reviews using lifetime abstainers or low-volume drinkers as a reference group

BACKGROUND AND AIMS

Systematic reviews of the relationship between alcohol consumption and all-cause mortality have reported different relative risk (RR) curves, possibly due to the choice of reference group. Results have varied from 'J-shaped' curves, where low-volume consumption is associated with reduced risk, to monotonically increased risk with increasing consumption. We summarised the evidence on alcohol consumption and all-cause mortality exclusively from systematic reviews using lifetime abstainers or low-volume/occasional drinkers as the reference group.

METHODS

We conducted a systematic umbrella review of systematic reviews of the relationship between alcohol consumption and all-cause mortality in prospective cohort studies using a reference group of lifetime abstainers or low-volume/occasional drinkers. Several databases (PubMed/Medline/Embase/PsycINFO/Cochrane Library) were searched to March 2022. Reviews were assessed for risk of bias, and those with reference groups containing former drinkers were excluded.

RESULTS

From 2149 articles retrieved, 25 systematic reviews were identified, and five did not include former drinkers in the reference group. Four of the five included reviews had high risk of bias. Three reviews reported a J-shaped relationship between alcohol consumption and all-cause mortality with significant decreased risk for low-volume drinking (RR range 0.84 to 0.95), while two reviews did not. The one review at low risk of bias reported monotonically increased risk with greater consumption (RRs = 1.02, 1.13, 1.33 and 1.52 for low-, medium-, high- and higher-volume drinking, respectively, compared with occasional drinking). All five reviews reported significantly increased risk with higher levels of alcohol consumption (RR range 1.28 to 3.70). Sub-group analyses were reported by sex and age; however, there were evidence gaps for many important factors. Conversely, 17 of 20 excluded systematic reviews reported decreased mortality risk for low-volume drinking.

CONCLUSIONS

Over 70% of systematic reviews and meta-analyses published to March 2022 of all-cause mortality risk associated with alcohol consumption did not exclude former drinkers from the reference group and may therefore be biased by the 'sick-quitter effect'.

Factors associated with the intrinsic capacity in older adults: A scoping review

INTRODUCTION

In 2015, the term 'intrinsic capacity' (IC) was proposed by the World Health Organisation to promote healthy aging. However, the factors associated with IC are still discrepant and uncertain.

AIM

We aim to synthesise the factors connected with IC.

METHODS

This scoping review followed the five-stage framework of Arksey and O'Malley and was reported using PRISMA-ScR guidelines.

RESULTS

In all, 29 articles were included. IC of older adults is associated with demographic characteristics, socioeconomic factors, disease conditions, behavioural factors, and biomarkers. Age, sex, marital status, occupation status, education, income/wealth, chronic diseases, hypertension, diabetes, disability, smoking status, alcohol consumption, and physical activity were emerged as important factors related to the IC of older adults.

CONCLUSIONS

This review shows that IC is related to multiple factors. Understanding these factors can provide the healthcare personnel with the theoretical basis for intervening and managing IC in older adults.

RELEVANCE TO CLINICAL PRACTICE

The influencing factors identified in the review help to guide older adults to maintain their own intrinsic capacity, thereby promoting their health and well-being. The modifiable factors also provide evidence for healthcare personnel to develop targeted intervention strategies to delay IC decline.

Association between alcohol use and frailty among elder adults in three Chinese cities

BACKGROUND

Frailty is often described as a condition of the elderly and alcohol use is associated with frailty. The aim of this study is to examine the associations between alcohol use and frailty in three cities in elder adults.

METHODS

A cross-sectional study was conducted in three cities in China from June 2017 to October 2018. In total, 2888 residents aged ≥65 years old were selected by using a multi-level stage sampling procedure. Alcohol use was assessed by Focusing on Cutting down, Annoyance by criticism, Guilty feeling, and Eye-openers (CAGE) four-item questionnaire. Frailty was measured by a validated Chinese version of the Fatigue, Resistance, Ambulation, Illness, and Loss of weight (FRAIL) scale. Multinomial logistic regressions were used to examine the association of alcohol use with pre-frailty and frailty after controlling for varied covariates.

RESULTS

In general, the prevalence of pre-frailty and frailty was 38.64 and 20.26%, respectively. After controlling for covariates and interaction of age and problematic drinking, non-problematic drinkers neither had association with pre-frailty (OR: 1.15, 95%CI:0.86-1.52) nor with frailty (OR:0.90, 95%CI:0.60-1.36), and problematic drinkers neither had association with frailty (OR: 1.21, 95%CI:0.83-1.76), while problematic drinkers had high odd ratios of frailty (OR:3.28, 95%CI:2.02-5.33) compared with zero-drinker.

CONCLUSIONS

Our study found a positive association between problematic drinking and frailty, no relationship between non-problematic drinking and (pre-)frailty compared with zero-drinking among Chinese elder adults. Based on previous findings and ours, we conclude it is important for the prevention of frailty to advocate no problematic drinking among elder adults.

Emergency Department Visits for Alcohol-Associated Falls Among Older Adults in the United States, 2011 to 2020

STUDY OBJECTIVE

The aim of this study was to examine the epidemiology of alcohol-associated fall injuries among older adults aged ≥65 years in the United States.

METHODS

We included emergency department (ED) visits for unintentional fall injuries by adults from the National Electronic Injury Surveillance System-All Injury Program during 2011 to 2020. We estimated the annual national rate of ED visits for alcohol-associated falls and the proportion of these falls among older adults' fall-related ED visits using demographic and clinical characteristics. Joinpoint regression was performed to examine trends in alcohol-associated ED fall visits between 2011 and 2019 among older adult age subgroups and to compare these trends with those of younger adults.

RESULTS

There were 9,657 (weighted national estimate: 618,099) ED visits for alcohol-associated falls, representing 2.2% of ED fall visits during 2011 to 2020 among older adults. The proportion of fall-related ED visits that were alcohol-associated was higher among men than among women (adjusted prevalence ratio [aPR]=3.6, 95% confidence interval [CI] 2.9 to 4.5). The head and face were the most commonly injured body parts, and internal injury was the most common diagnosis for alcohol-associated falls. From 2011 to 2019, the annual rate of ED visits for alcohol-associated falls increased (annual percent change 7.5, 95% CI 6.1 to 8.9) among older adults. Adults aged 55 to 64 years had a similar increase; a sustained increase was not detected in younger age groups.

CONCLUSION

Our findings highlight the rising rates of ED visits for alcohol-associated falls among older adults during the study period. Health care providers in the ED can screen older adults for fall risk and assess for modifiable risk factors such as alcohol use to help identify those who could benefit from interventions to reduce their risk.

Concurrent serum lead levels and cognitive function in older adults

Introduction

In this study, we investigated the relationship between serum lead levels and cognitive functioning in a sample of older adults in the US.

Method

Using the National Health and Nutrition Examination Survey (NHANES) 2011-2013, a total of 768 older adults aged ≥60 years were included in the analysis. Lead concentrations in the whole blood samples were assessed using mass spectrometry. We used the immediate and delayed memory portions of the Consortium to Establish a Registry for Alzheimer's Disease Word Learning Subtest (CERAD-WL), the Animal Fluency Test (AFT), and the Digit Symbol Substitution Test (DSST) to assess the participants' cognitive performance. Using sample averages and standard deviations (SDs), we computed test-specific and global cognition z-scores. To assess the relationships between the quartiles of serum lead levels and cognitive performance, we built multiple linear regression models and adjusted for covariates, including age, sex, race/ethnicity, education, depressive symptoms, alcohol usage, and body mass index.

Results

The average age of the participants was 69.6 (SD 6.6) years. Approximately half of the participants were women (52.6%), non-Hispanic white (52.0%), and had completed at least some college education (51.8%). The average serum lead concentration was 1.8 g/dL (SD 1.6) for these participants. The results of multiple linear regression using individuals in the lowest serum lead quantile as a reference group revealed that the serum lead level was not associated with test-specific (CERAD-WL, AFT, and DSST) or global cognitive z-scores.

Conclusions

In older adults, concurrent serum lead concentration is not related to cognitive performance. Early or continuous lead exposure may exert a greater effect on the etiology of accelerated cognitive decline with old age.

Alcohol and the Risk of Injury

Globally, almost four and a half million people died from injury in 2019. Alcohol's contribution to injury-related premature loss of life, disability and ill-health is pervasive, touching individuals, families and societies throughout the world. We conducted a review of research evidence for alcohol's causal role in injury by focusing on previously published systematic reviews, meta-analyses and where indicated, key studies. The review summarises evidence for pharmacological and physiological effects that support postulated causal pathways, highlights findings and knowledge gaps relevant to specific forms of injury (i.e., violence, suicide and self-harm, road injury, falls, burns, workplace injuries) and lays out options for evidence-based prevention.

The importance of alcohol in elderly's hospital admissions for fall injuries: a population case-control study

Background:

Fall injuries account for a substantial part of the health burden among elderly persons, and they often affect life quality severely and impose large societal costs. Alcohol intoxication is a well-known risk factor for accidental injuries, but less is known about this association among elderly people. In this study, our aim was to assess whether risk of fall injuries among the elderly is elevated with an intoxication-oriented drinking pattern.

Method:

We applied a population case-control design and data from persons aged 60 years and over in Norway. Cases comprised patients with fall injuries admitted to a hospital emergency department ( n = 424), and controls were participants in general population surveys ( n = 1859). Drinking pattern was assessed from self-reports of drinking frequency and intoxication frequency. Age and gender-adjusted association between fall injury and drinking pattern was estimated in logistic regression models. Fall injuries were considered alcohol-related if blood alcohol concentration exceeded 0.01% and/or the patient reported alcohol intake within six hours prior to injury.

Results:

The risk of fall injuries was highly elevated among those reporting drinking to intoxication monthly or more often ( OR = 10.2, 95% CI 5.5–19.0). Among cases, the vast majority of those with alcohol-related fall injuries (64 of 68) reported drinking to intoxication.

Conclusions:

A drinking pattern comprising alcohol intoxication elevated the risk of fall injuries among elderly people. As alcohol use is a modifiable risk factor, the findings suggest a potential to curb the number of fall injuries and their consequences by employing effective strategies to prevent intoxication drinking among the elderly.

Fall-related emergency department visits involving alcohol among older adults

PROBLEM

Falls are the leading cause of injury deaths among adults aged 65 years and older. Characteristics of these falls may vary with alcohol use.

OBJECTIVE

Describe and compare characteristics of older adult fall-related emergency department (ED) visits with indication of alcohol to visits with no indication.

METHODS

Using nationally-representative 2015 National Electronic Injury Surveillance System-All Injury Program data, we compared demographic characteristics for fall-related ED visits by indication of alcohol consumption. Alcohol-indicated ED visits were matched on age group, sex, treatment month, and treatment day to ED visits with no alcohol indication using a 1:4 ratio and injury characteristics (i.e., diagnosis, body part injured, disposition) were compared.

RESULTS AND DISCUSSION

Of 38,640 ED records, 906 (1.9%) indicated use of alcohol. Fall-related ED visits among women were less likely to indicate alcohol (1.0%) compared to ED visits among men (3.8%). ED visits indicating alcohol decreased with age from 4.1% for those 65-74 years to 1.5% for those 75-84 and <1% for those 85+. After controlling for age-group, sex, and month and day of treatment, 17.0% of ED visits with no alcohol indication had a traumatic brain injury compared to 34.8% of alcohol-indicated ED visits. Practical applications: Alcohol-indicated fall ED visits resulted in more severe head injury than those that did not indicate alcohol. To determine whether alcohol use should be part of clinical risk assessment for older adult falls, more routinely collected data and detailed information on the amount of alcohol consumed at the time of the fall are needed.

Impact of Individual and Combined Lifestyle Factors on Mortality in China: A Cohort Study

INTRODUCTION

Although numerous studies have suggested that lifestyle-related factors are associated with chronic diseases and preventable deaths, limited evidence is available for the Chinese population.

METHODS

This study established a prospective cohort of >360,000 residents on the basis of the Yinzhou Health Information System in China during 2004-2017 and calculated the combined effects of lifestyle-related factors, including BMI, smoking, alcohol consumption, and physical activity, using a points system. A Cox regression model estimated the combined effects of lifestyle-related factors on total mortality, and a competing risk model estimated the combined effects on cancer and cardiovascular disease mortality. All data analyses were conducted in 2018‒2019.

RESULTS

During 3,755,879 person-years of follow-up, 11,791 deaths were identified, including 4,983 from cancer and 3,143 from cardiovascular disease. Having a standard BMI, never smoking, never drinking, and engaging in physical activity more than 4 times per week had protective effects on total mortality. Overall, the risk of total and cause-specific mortality increased with the increment of risk score. Compared with subjects in the lowest quartile, the risk of total and cause-specific mortality peaked among individuals in the fourth quartile (total mortality: hazard ratio=1.87, 95% CI=1.77, 1.98; cancer mortality: hazard ratio=2.05, 95% CI=1.87, 2.25; cardiovascular disease mortality: hazard ratio=1.51, 95% CI=1.35, 1.68). Sensitivity analyses excluding individuals with follow-up <3 years did not materially change the results.

CONCLUSIONS

The combined effects of lifestyle-related factors, including BMI, smoking, alcohol drinking, and physical activity, are associated with total, cancer, and cardiovascular disease mortality among the Chinese population.

Falls Among the Elderly in Peruvian Andean Communities and the Rural far South of Brazil: Prevalence and Associated Factors

Falls are the fifth leading cause of death and are one of the main causes of hospitalization. The literature about falls prevalence among older adults living in rural/remote communities in South America is scarce. To compare falls prevalence among the elderly in the Andes, Peru, and in the rural area of the municipality of Rio Grande, Rio Grande do Sul state, Brazil. Two separate cross-sectional studies were conducted in Peru, Andes (N = 413), and Brazil, Rio Grande, Rio Grande do Sul state (N = 1029). We stratified all data analysis according to location (Andes/Rio Grande). Characteristics of the samples were compared and the chi square test for proportions was used. Falls prevalence was then calculated for each independent variable and crude and adjusted prevalence ratios were estimated using Poisson Regression with robust variance. Falls prevalence in the last year was much higher in the Andes (64.1%) than in Rio Grande (25.3%). For most characteristics assessed, falls prevalence in Peru was at least double that found in Rio Grande. According to the adjusted analysis for the Andes, age (80 or more), being married, divorced and alcohol intake were significantly associated with falls. In Rio Grande, female gender and being in the 70-79 and 80 or more age ranges were associated with falls as well as those who self-rated their health as poor. This paper contributes to knowledge about falls prevalence among the elderly from rural and remote communities in two South American countries. Longitudinal multicentre studies with standardized methodologies are recommended.

Lifestyle Risk Factors and All-Cause and Cardiovascular Disease Mortality: Data from the Korean Longitudinal Study of Aging

This study examined the association between lifestyle risk factors and all-cause and cardiovascular disease (CVD) mortality in 9945 Korea adults (56% women) aged 45 years and older. Smoking, heavy alcohol intake, underweight or obesity, physical inactivity, and unintentional weight loss (UWL) were included as risk factors. During 9.6 ± 2.0 years of follow-up, there were a total of 1530 cases of death from all causes, of which 365 cases were from CVD. Compared to a zero risk factor (hazard ratio, HR = 1), the crude HR of all-cause mortality was 1.864 (95% CI, 1.509–2.303) for one risk factor, 2.487 (95% confidence interval, CI, 2.013–3.072) for two risk factors, and 3.524 (95% CI, 2.803–4.432) for three or more risk factors. Compared to a zero risk factor (HR = 1), the crude HR of CVD mortality was 2.566 (95% CI, 1.550–4.250) for one risk factor, 3.655 (95% CI, 2.211–6.043) for two risk factor, and 5.416 (95% CI, 3.185–9.208) for three or more risk factors. The HRs for all-cause and CVD mortality remained significant even after adjustments for measured covariates. The current findings showed that five lifestyle risk factors, including smoking, at-risk alcohol consumption, underweight/obesity, physical inactivity, and UWL, were significantly associated with an increased risk of all-cause and CVD mortality in Korean adults.

Alcohol use and dementia: a systematic scoping review

BACKGROUND

Alcohol use has been identified as a risk factor for dementia and cognitive decline. However, some patterns of drinking have been associated with beneficial effects.

METHODS AND RESULTS

To clarify the relationship between alcohol use and dementia, we conducted a scoping review based on a systematic search of systematic reviews published from January 2000 to October 2017 by using Medline, Embase, and PsycINFO. Overall, 28 systematic reviews were identified: 20 on the associations between the level of alcohol use and the incidence of cognitive impairment/dementia, six on the associations between dimensions of alcohol use and specific brain functions, and two on induced dementias. Although causality could not be established, light to moderate alcohol use in middle to late adulthood was associated with a decreased risk of cognitive impairment and dementia. Heavy alcohol use was associated with changes in brain structures, cognitive impairments, and an increased risk of all types of dementia.

CONCLUSION

Reducing heavy alcohol use may be an effective dementia prevention strategy.

Association of Fruit and Vegetable Intake and Frailty among Chinese Elders: A Cross-Sectional Study in Three Cities

OBJECTIVES

To examine the association of FVI and frailty in Chinese elders.

DESIGN

A sectional study was conducted in three cities (Shanghai, Zhengzhou, and Baoji) in China from June 2017 to June 2018.

PARTICIPANTS

A total of 5699 participants from 49 districts were included in the current study by two-stage sampling methods.

MEASUREMENTS

Frailty was measured by a validated Chinese version of the FRAIL scale. FVI per day was measured by two single questions.

RESULTS

The sample proportion with sufficient fruit intake was 36.7%, and 44.7% reported sufficient vegetable intake. The sample proportions that were robust, pre-frail, and frail were 43.6%, 38.3%, and 18.1%, respectively. Compared with low FVI, after including covariates, the odds ratio (OR) of frailty was 0.84 (95% CI: 0.73-0.97) for moderate fruit intake and 0.81 (95% CI: 0.70-0.94) for enough fruit intake; the OR of frailty was 0.83 (95% CI: 0.68-0.91) for moderate vegetable intake and 0.77 (95% CI: 0.64-0.93) for enough vegetable intake.

CONCLUSION

High FVI was negatively associated with the OR of frailty in Chinese elders. This finding implies it is important to promote FVI among adults to prevent frailty.

Increased Alcohol Consumption Among Swedish 70-Year-Olds 1976 to 2016: Analysis of Data from The Gothenburg H70 Birth Cohort Studies, Sweden

BACKGROUND

The older adult population is increasing worldwide, as is the number of older adults who consume alcohol. Although there is a growing body of research on alcohol consumption among older people, few studies focus on changes in at-risk consumption over time across well-defined birth cohorts of older adults.

METHODS

This study used a serial cross-sectional design in order to compare alcohol consumption patterns among birth cohorts of Swedish 70-year-olds (total n = 2,268) examined in 1976 to 1977 (n = 393), 1992 to 1993 (n = 248), 2000 to 2002 (n = 458), and 2014 to 2016 (n = 1,169). Participants took part in a multidisciplinary study on health and aging. Face-to-face interviews were conducted by healthcare professionals. Protocols regarding alcohol consumption were similar for all cohorts. The volume of weekly alcohol consumption was estimated during the past month. At-risk consumption was defined as ≥100 g alcohol/wk corresponding roughly to the National Institute on Alcohol Abuse and Alcoholism definition of heavy consumption.

RESULTS

The proportion of at-risk consumers among men increased from 16.1% in 1976 to 1977 to 29.9% in 2000 to 2002 (p = 0.001) and 45.3% in 2014 to 2016 (p < 0.001). In women, proportions were low in 1976 to 1977 (0.5%) and 1992 to 1993 (2.0%; p = 0.134), but increased to 9.5% in 2000 to 2002 (p < 0.001) and 24.3% in 2014 to 2016 (p < 0.001). The male:female ratio regarding consumption of ≥100 g/wk decreased from 32.2:1 in 1976 to 1977 to 3.1:1 in 2000 to 2002 to 1.9:1 in 2014 to 2016. Spirit consumption decreased dramatically among men during the study period, while women reported very low spirit consumption at all examinations. Wine consumption increased in both sexes between 2000 to 2002 and 2014 to 2016. Beer consumption increased among men between 2000 to 2002 and 2014 to 2016.

CONCLUSIONS

Recent cohorts of 70-year-olds in Sweden report significantly higher levels of alcohol consumption than previous cohorts. There was a dramatic increase in at-risk consumption among 70-year-olds from the 1970s to the mid-2010s, and this was particularly pronounced among women.

Associations of smoking and alcohol consumption with healthy ageing: a systematic review and meta-analysis of longitudinal studies

OBJECTIVES

The number of older people is growing across the world; however, quantitative synthesis of studies examining the impact of lifestyle factors on the ageing process is rare. We conducted a systematic review and meta-analysis of longitudinal studies to synthesise the associations of smoking and alcohol consumption with healthy ageing (HA).

METHODS

Major electronic databases were searched from inception to March 2017 (prospectively registered systematic reviews registration number CRD42016038130). Studies were assessed for methodological quality. Random-effect meta-analysis was performed to calculate pooled ORs and 95% CI.

RESULTS

In total, we identified 28 studies (n=184 543); 27 studies reported results on smoking, 22 on alcohol consumption. 23 studies reported a significant positive association of never or former smoking with HA and 4 non-significant. 12 studies reported a significant positive association of alcohol consumption with HA, 9 no association and 1 negative. Meta-analysis revealed increased pooled OR of HA for never smokers compared with current smokers (2.36, 95% CI 2.03 to 2.75), never smokers compared with former smokers (1.32, 95% CI 1.23 to 1.41), former or never smokers compared with current smokers (1.72, 95% CI 1.20 to 2.47), never smokers compared with past or current smokers (1.29, 95% CI 1.16 to 1.43); drinkers compared with non-drinkers (1.28, 95% CI 1.08 to 1.52), light drinkers compared with non-drinkers (1.12, 95% CI 1.03 to 1.22), moderate drinkers compared with non-drinkers (1.35, 95% CI 0.93 to 1.97) and high drinkers compared with non-drinkers (1.25, 95% CI 1.09 to 1.44). There was considerable heterogeneity in the definition and measurement of HA and alcohol consumption.

CONCLUSIONS

There is consistent evidence from longitudinal studies that smoking is negatively associated with HA. The associations of alcohol consumption with HA are equivocal. Future research should focus on the implementation of a single metric of HA, on the use of consistent drinking assessment among studies and on a full-range of confounding adjustment. Our research also highlighted the limited research on ageing in low-and-middle-income countries.

Adverse Childhood Experiences and Substance Use History among Vulnerable Older Adults Living in Public Housing

Previous research shows strong correlations between adverse childhood experiences (ACE) and later life health. The current study examines the relationship between ACEs and substance use among older adults living in public housing. Results show that about one-third of participants had four or more ACEs, and ACE score predicted likelihood of substance use history. Over half of older adults with four or more ACEs experienced substance abuse in their lifetime compared to one out of ten older adults with less than four ACEs. Findings shed light on a vulnerable group and point to next steps in research and practice.

Relationship of moderate alcohol intake and type of beverage with health behaviors and quality of life in elderly subjects

PURPOSE

This work was aimed to study the relationships of moderate alcohol intake and the type of beverages consumed with health behaviors and quality of life in elderly people.

METHODS

In this observational study, 231 subjects (55-85 years) voluntarily answering to advertisements were enrolled and divided in three study groups: abstainers and occasional consumers (ABS; n = 98), moderate drinkers of beer (BEER; n = 63) and moderate drinkers of all sorts of alcoholic beverages (MIXED; n = 70). Variables assessed included physical activity, activities of daily living, Mediterranean diet-adherence score, tobacco consumption, quality of sleep, body composition, medication and perception of health through the SF-36 questionnaire. Their relationship with alcohol consumption was assessed through general linear models including confounding variables (age, sex, chronic disease prevalence and socioeconomic status). ABS were also compared to moderate drinkers (MOD = BEER + MIXED).

RESULTS

The mean daily alcohol consumption in each group was (mean ± SD): ABS: 0.7 ± 1.1; BEER: 12.7 ± 8.1; MIXED: 13.9 ± 10.2 g/day. MOD and MIXED showed significantly higher physical activity (metabolic standard units; METs) than ABS (p = 0.023 and p = 0.004, respectively). MOD spent significantly less time doing housework activities than ABS (p = 0.032). Daily grams of alcohol consumption were significantly associated with METs (B = 21.727, p = 0.023). Specifically, wine consumption (g/day) was associated with METs (B = 46.196, p = <0.001) and showed borderline significant relationships with mental health (B = 0.245, p = 0.062) and vitality perception (B = 0.266, p = 0.054).

CONCLUSION

Moderate alcohol consumption, and in particular wine consumption, is associated with a more active lifestyle and better perception of own health in the Spanish elderly subjects studied.

Alcohol use, socioeconomic deprivation and ethnicity in older people

OBJECTIVES

This study explores the relationship between alcohol consumption, health, ethnicity and socioeconomic deprivation.

PARTICIPANTS

27,991 people aged 65 and over from an inner-city population, using a primary care database.

PRIMARY AND SECONDARY OUTCOME MEASURES

Primary outcome measures were alcohol use and misuse (>21 units per week for men and >14 for units per week women).

RESULTS

Older people of black and minority ethnic (BME) origin from four distinct ethnic groups comprised 29% of the sample. A total of 9248 older drinkers were identified, of whom 1980 (21.4%) drank above safe limits. Compared with older drinkers, older unsafe drinkers contained a higher proportion of males, white and Irish ethnic groups and a lower proportion of Caribbean, African and Asian groups. For older drinkers, the strongest independent predictors of higher alcohol consumption were younger age, male gender and Irish ethnicity. Independent predictors of lower alcohol consumption were Asian, black Caribbean and black African ethnicity. Socioeconomic deprivation and comorbidity were not significant predictors of alcohol consumption in older drinkers. For older unsafe drinkers, the strongest predictor variables were younger age, male gender and Irish ethnicity; comorbidity was not a significant predictor. Lower socioeconomic deprivation was a significant predictor of unsafe consumption whereas African, Caribbean and Asian ethnicity were not.

CONCLUSIONS

Although under-reporting in high-alcohol consumption groups and poor health in older people who have stopped or controlled their drinking may have limited the interpretation of our results, we suggest that closer attention is paid to 'young older' male drinkers, as well as to older drinkers born outside the UK and those with lower levels of socioeconomic deprivation who are drinking above safe limits.

Examining the Impact of Separate Components of a Multicomponent Intervention Designed to Reduce At-Risk Drinking Among Older Adults: The Project SHARE Study

BACKGROUND

Health promotion interventions often include multiple components and several patient contacts. The objective of this study was to examine how participation within a multicomponent intervention (Project SHARE) is associated with changes in at-risk drinking among older adults.

METHODS

We analyzed observational data from a cluster-randomized trial of 31 primary care physicians and their patients aged ≥60 years, at a community-based practice with 7 clinics. Recruitment occurred between 2005 and 2007. At-risk drinkers in a particular physician's practice were randomly assigned as a group to usual care (n = 640 patients) versus intervention (n = 546 patients). The intervention included personalized reports, educational materials, drinking diaries, in-person physician advice, and telephone counseling by health educators (HEs). The primary outcome was at-risk drinking at follow-up, defined by scores on the Comorbidity Alcohol Risk Evaluation Tool (CARET). Predictors included whether a physician-patient alcohol risk discussion occurred, HE call occurred, drinking agreement with the HE was made, and patients self-reported keeping a drinking diary as suggested by the HE.

RESULTS

At 6 months, there was no association of at-risk drinking with having had a physician-patient discussion. Compared to having had no HE call, the odds of at-risk drinking at 6 months were lower if an agreement was made or patients reported keeping a diary (odds ratio [OR] 0.58, 95% confidence interval [CI] 0.37 to 0.90), or if an agreement was made and patients reported keeping a diary (OR 0.52, CI 0.28 to 0.97). At 12 months, a physician-patient discussion (OR 0.61, CI 0.38 to 0.98) or an agreement and reported use of a diary (OR 0.45, CI 0.25) were associated with lower odds of at-risk drinking.

CONCLUSIONS

Within the Project SHARE intervention, discussing alcohol risk with a physician, making a drinking agreement, and/or self-reporting the use of a drinking diary were associated with lower odds of at-risk drinking at follow-up. Future studies targeting at-risk drinking among older adults should consider incorporating both intervention components.

Secular changes in at-risk drinking in Sweden: birth cohort comparisons in 75-year-old men and women 1976-2006

Background: little is known about the prevalence of at-risk drinking in older adults.

Objective: to compare rates of at-risk drinking in 75-year-olds examined in 1976–77 and in 2005–06.

Design: cross-sectional survey.

Setting: two samples representative of the general population in Gothenburg, Sweden.

Participants: 75-year-olds born in 1901–02 (n = 303) and in 1930 (n = 753).

Methods: participants took part in a multidisciplinary study on health and ageing. Protocols regarding alcohol consumption were identical for both cohorts. Total weekly alcohol intake was estimated and at-risk drinking was defined as ≥100 g alcohol/week.

Results: the proportion abstaining differed significantly between birth cohorts (18% in 1976–77 versus 9% in 2005, P < 0.001). Frequencies of drinking beer and liquor were similar in the two cohorts for men, but were lower for women in the later-born cohort. Proportions drinking wine were higher in the later-born cohort for both sexes. Total weekly alcohol intake was higher for both men and women. At-risk drinking was observed in 19.3% of the men in the earlier-born cohort, and in 27.4% in the later-born cohort (P = 0.117). Corresponding figures for women were 0.6 and 10.4% (P < 0.001). At-risk drinking was significantly associated with birth cohort in women (OR: 13.77, CI: 1.82–104.0, P = 0.011) and the occupational group in men (OR: 1.60, CI: 1.13–2.26, P = 0.008).

Conclusions: alcohol consumption in 75-year-olds has changed markedly, especially in women. Studies need to be carried out in varied settings in order to evaluate the clinical and public health implications of changing trends in alcohol consumption.

Alcohol and trauma--in every age group

BACKGROUND

The purpose was to determine the proportion of alcohol-positive (AlcPos) trauma patients in different age groups and any association with mortality using the National Trauma Data Bank.

METHODS

Several variables were extracted from the National Trauma Data Bank (version 6.2) using MS Access 2007: age, alcohol presence, Injury Severity Score (ISS), and discharge status (alive vs dead). Age groups for logistic regression were arbitrarily defined as follows: 0 to 10, 11 to 20, 21 to 39, 40 to 64, and older than 64 years.

RESULTS

Approximately 47% of all trauma survivors were tested for alcohol (621,174 of a total of 1,311,137), and 28% of those were AlcPos (176,107/621,174). The proportion of AlcPos patients gradually increased to maximum at 22 years, when 46% (6797/14,732) tested were AlcPos. The proportion AlcPos gradually declined to 35% by age 50 years, then to 15% (2516/16,244) by age 66 to 70 years. The ISSs were significantly higher in AlcPos patients in all age groups (P < .01). Mortality rates were higher in AlcPos children (up to age 20 years) and in adults older than 40 years. The AlcPos patients who were 21 to 39 years old had lower mortality compared with alcohol-negative patients. Logistic regression analysis (controlling for ISSs) revealed that being AlcPos did not play a role in mortality until age 21 to 39 years (AlcPos lower mortality) and in age 40 to 64 years and older than 65 years (AlcPos higher mortality).

CONCLUSIONS

Trauma patients of all ages may be AlcPos. Being AlcPos is a marker for greater injury in all age groups. After controlling for ISSs, trauma patients 40 years and older who were AlcPos have increased mortality. This study suggests a role for alcohol testing in all age groups.

Moderate alcohol consumption predicts long-term mortality in elderly subjects with chronic heart failure

OBJECTIVE

Moderate alcohol consumption is related to a reduction of mortality. However, this phenomenon is not well established in the elderly, especially in the presence of chronic heart failure (CHF). The aim of the study was to verify the effect of moderate alcohol consumption on 12-year mortality in elderly community-dwelling with and without CHF.

SETTINGS

community-dwelling from 5 regions of Italy.

PARTICIPANTS

A cohort of 1332 subjects aged 65 and older.

MEASUREMENT

Mortality after 12-year follow-up in elderly subjects (≥65 years old) with and without CHF was studied. Moderate alcohol consumption was considered ≤250 ml/day (drinkers).

RESULTS

In the absence of CHF (n=947), mortality was 42.2% in drinkers vs. 53.7% in non-drinker elderly subjects (p=0.021). In contrast, in the presence of CHF (n=117), mortality was 86.5% in drinkers vs. 69.7% in non-drinker elderly subjects (p=0.004). Accordingly, Cox regression analysis shows that a moderate alcohol consumption is protective of mortality in the absence (HR=0.79; CI 95% 0.66-0.95; p<0.01) but it is predictive of mortality in the presence of CHF (HR=1.29; CI 95% 1.05-1.97; p<0.05).

CONCLUSIONS

Our data demonstrates that moderate alcohol consumption is associated with an increased long-term mortality risk in the elderly in the presence of CHF.

Drinking patterns and the development of functional limitations in older adults: longitudinal analyses of the health and retirement survey

OBJECTIVE

To examine whether consistent low-risk drinking is associated with lower risk of developing functional limitations among older adults.

METHOD

Data were obtained from five waves of the Health and Retirement Study. Function was assessed by questions measuring four physical abilities and five instrumental activities of daily living. Five different drinking patterns were determined using data over two consecutive survey periods.

RESULTS

Over the follow-up periods, 38.6% of older adults developed functional limitations. Consistent low-risk drinkers had lower odds of developing functional limitations compared with consistent abstainers, and the effect of consistent low-risk drinking was greater among those aged 50 to 64 years compared with those aged ≥65 years. Other drinking patterns were not associated with lower odds of incident functional limitation.

DISCUSSION

Consistent low-risk drinking was associated with lower odds of developing functional limitations, and this association was greater among older middle-aged adults aged 50 to 64 years.

Alcohol consumption and health status in very old veterans

Previous research has linked drinking with health, but has yet to address alcohol consumption and the relationship between drinking and health among very old veterans. To help fill this gap, the authors present a cross-sectional self-report study on 1105 veterans age 90 and older who completed the national Veteran's Affairs (VA) Survey of the Health Experiences of Patients (SHEP) for fiscal year (FY) 2005. Alcohol consumption was measured using Alcohol Use Disorders Identification Test scores (AUDIT-C). Health status was measured using the Veterans Rand Health Survey: VR-12. Among men (n = 1063), 60% were abstainers. No significant differences in mental health component (MCS; F(3,1040) = 1.80, P = .15) or physical health component (PCS; F(3,1040) = 1.48, P = .22) scores were detected across consumption categories. Among women (n = 42), 47% were abstainers. These results suggest many very old veterans abstain from alcohol and, among men, the associations between health status and drinking observed in younger groups may not be present in very old age.

Correlates of alcohol-related discussions between older adults and their physicians

OBJECTIVES

To identify predictors of alcohol-related patient-physician discussions.

DESIGN

Cross-sectional study using baseline data from a randomized controlled trial.

SETTING

Community-based group practice.

PARTICIPANTS

Thirty-one physicians in Project Senior Health and Alcohol Risk Education and 3,305 of their patients aged 60 and older who use alcohol and completed a survey that included the Comorbidity Alcohol Risk Evaluation Tool (CARET).

MEASUREMENTS

At study baseline, older adults were asked whether alcohol-related discussions with a physician had occurred in the prior year. This outcome was modeled using logistic regression models with physician random effects. Predictor variables included patient-level variables such as demographics and seven CARET-defined risk factors, specifically a medical or psychiatric comorbidity that alcohol might worsen, a potentially alcohol-related symptom, use of a medication that may interact negatively with alcohol, excessive quantity or frequency of alcohol use, binge drinking, concern from others about drinking, and drinking and driving. Physician-level predictors (age, sex, years since graduation, specialty) were also included.

RESULTS

The probability of reporting alcohol-related discussions declined with patient age (e.g., odds ratio (OR)=0.40 for patients aged ≥80) and was significantly lower for Latinos (OR=0.38). Drinking and driving (OR=1.69) or concern from others (OR=6.04) were significantly associated with alcohol-related discussions; having comorbidities or using medications that may interact with alcohol were not.

CONCLUSION

Although patient demographics, including age and ethnicity, are associated with the occurrence of alcohol-related discussions, clinical factors that may negatively interact with alcohol to increase risk are not. This suggests that physicians may not be attuned to the entire spectrum of alcohol-related risks for older adults.

How Gender and Religion Influence Alcohol Use in Elderly Korean Immigrants

This study examined the effects of religion and gender on drinking behaviors among a sample of 148 older Korean immigrants living in a metropolitan area in Canada. Face-to-face interviews were conducted using standardized questions. The mean age of the participants was 74 years (range: 60-97 years). Logistic regression models were used to assess the effects of religion on drinking and heavier drinking and gender differences in correlates of current drinking and heavier drinking. Results revealed that being married and having lower religiosity were significant correlates that increased the odds of being a current drinker. Older Korean men tend to engage in heavier drinking behavior. Higher religiosity, not mere affiliation to Protestant churches, decreased the odds of heavier drinking for both men and women. The odds of heavier drinking increased for depressed men. Study limitations and implications are presented in a cultural context.

Patterns of drug use and abuse among aging adults with and without HIV: a latent class analysis of a US Veteran cohort

This study characterized the extent and patterns of self-reported drug use among aging adults with and without HIV, assessed differences in patterns by HIV status, and examined pattern correlates. Data derived from 6351 HIV-infected and uninfected adults enrolled in an eight-site matched cohort, the Veterans Aging Cohort Study (VACS). Using clinical variables from electronic medical records and socio-demographics, drug use consequences, and frequency of drug use from baseline surveys, we performed latent class analyses (LCA) stratified by HIV status and adjusted for clinical and socio-demographic covariates. Participants were, on average, age 50 (range 22-86), primarily male (95%) and African-American (64%). Five distinct patterns emerged: non-users, past primarily marijuana users, past multidrug users, current high consequence multidrug users, and current low consequence primarily marijuana users. HIV status strongly influenced class membership. Non-users were most prevalent among HIV uninfected (36.4%) and current high consequence multidrug users (25.5%) were most prevalent among HIV-infected. While problems of obesity marked those not currently using drugs, current users experienced higher prevalences of medical or mental health disorders. Multimorbidity was highest among past and current multidrug users. HIV-infected participants were more likely than HIV-uninfected participants to be current low consequence primarily marijuana users. In this sample, active drug use and abuse were common. HIV-infected and uninfected Veterans differed on extent and patterns of drug use and on important characteristics within identified classes. Findings have the potential to inform screening and intervention efforts in aging drug users with and without HIV.

Alcohol consumption and all-cause mortality among elderly in Finland

AIMS

To estimate the gender-specific prevalences of alcohol consumption levels and to investigate the association between heavy drinking and all-cause mortality among elderly males.

DESIGN

A cohort derived from a nationally representative sample of Finns aged >65 years was followed for six years. Number of subjects was 1569 (72.7% of the original sample, 65.3% females, weighted n=1357).

MEASUREMENTS

Alcohol consumption was retrospectively measured by beverage-specific quantity and frequency over a 12-month period. Mortality data were obtained from the official Cause-of-Death Register. Cox proportional hazards models were used to analyse the relative risks (RRs) of death.

FINDINGS

The prevalence of heavy drinking (>8 standard drinks per week) was 20.3% in males and 1.2% in females. Over one-tenth (11.4%) of males reported drinking > or =15 standard drinks per week. Relative death risks suggested a J-curved relationship between alcohol consumption levels and mortality. However, significant curvilinear relationship was not found, when using alcohol consumption as continuous variable. The multivariate adjusted RR of death among moderate drinkers (1-7 drinks per week) vs. abstinent subjects was 0.41 (95% CI=.23-.72). Males drinking > or =15 standard drinks per week had a two-fold multivariate adjusted risk of death (RR=2.11, 95% CI=1.19-3.75) compared with abstinent males. The level of alcohol consumption by females was too low for analysis.

CONCLUSIONS

Heavy drinking is common among Finnish elderly males but not among females. The present study shows an increased all-cause mortality risk for males drinking, on average, more than two standard drinks per day.

Heterogeneity in red wine polyphenolic contents differentially influences Alzheimer's disease-type neuropathology and cognitive deterioration

We recently found that moderate consumption of two unrelated red wines generate from different grape species, a Cabernet Sauvignon and a muscadine wine that are characterized by distinct component composition of polyphenolic compounds, significantly attenuated the development of Alzheimer's disease (AD)-type brain pathology and memory deterioration in a transgenic AD mouse model. Interestingly, our evidence suggests that the two red wines attenuated AD phenotypes through independent mechanisms. In particular, we previously found that treatment with Cabernet Sauvignon reduced the generation of AD-type amyloid-beta (Abeta) peptides. In contrast, evidence from our present study suggests that muscadine treatment attenuates Abeta neuropathology and Abeta-related cognitive deterioration in Tg2576 mice by interfering with the oligomerization of Abeta molecules to soluble high-molecular-weight Abeta oligomer species that are responsible for initiating a cascade of cellular events resulting in cognitive decline. Collectively, our observations suggest that distinct polyphenolic compounds from red wines may be bioavailable at the organism level and beneficially modulate AD phenotypes through multiple Abeta-related mechanisms. Results from these studies suggest the possibility of developing a "combination" of dietary polyphenolic compounds for AD prevention and/or therapy by modulating multiple Abeta-related mechanisms.

Functional limitations, socioeconomic status, and all-cause mortality in moderate alcohol drinkers

OBJECTIVES

To determine whether the survival benefit associated with moderate alcohol use remains after accounting for nontraditional risk factors such as socioeconomic status (SES) and functional limitations.

DESIGN

Prospective cohort.

SETTING

The Health and Retirement Study (HRS), a nationally representative study of U.S. adults aged 55 and older.

PARTICIPANTS

Twelve thousand five hundred nineteen participants were enrolled in the 2002 wave of the HRS.

MEASUREMENTS

Participants were asked about their alcohol use, functional limitations (activities of daily living, instrumental activities of daily living, and mobility), SES (education, income, and wealth), psychosocial factors (depressive symptoms, social support, and the importance of religion), age, sex, race and ethnicity, smoking, obesity, and comorbidities. Death by December 31, 2006, was the outcome measure.

RESULTS

Moderate drinkers (1 drink/d) had a markedly more-favorable risk factor profile, with higher SES and fewer functional limitations. After adjusting for demographic factors, moderate drinking (vs no drinking) was strongly associated with less mortality (odds ratio (OR)=0.50, 95% confidence interval (CI)=0.40-0.62). When traditional risk factors (smoking, obesity, and comorbidities) were also adjusted for, the protective effect was slightly attenuated (OR=0.57, 95% CI=0.46-0.72). When all risk factors including functional status and SES were adjusted for, the protective effect was markedly attenuated but still statistically significant (OR=0.72, 95% CI=0.57-0.91).

CONCLUSION

Moderate drinkers have better risk factor profiles than nondrinkers, including higher SES and fewer functional limitations. Although these factors explain much of the survival advantage associated with moderate alcohol use, moderate drinkers maintain their survival advantage even after adjustment for these factors.

Light to moderate alcohol consumption and disability: variable benefits by health status

In adults, light to moderate alcohol consumption is associated with lower risks for heart disease, diabetes, and mortality. This study examined whether light to moderate alcohol use is also associated with lower risk of incident physical disability over two 5-year periods in 4,276 noninstitutionalized adults in the United States, aged 50 years or older, by using data from 3 waves of the National Health and Nutrition Examination Survey Epidemiologic Follow-up Study surveys from 1982 to 1992. Light/moderate drinking (<15 drinks per week and <5 per drinking day or 4 per drinking day for women) was associated with reduced risk for incident disability or death over 5 years, compared with abstention (adjusted odds ratio = 0.77; P = 0.008). Among survivors, light/moderate drinking was associated with lower risk for incident disability, compared with abstention (adjusted odds ratio = 0.75; P = 0.009). In stratified analyses, disability risk decreased with light/moderate drinking in a dose-dependent fashion in men and women with good or better self-reported health but not in men or women with fair or worse self-reported health. Alcohol consumption in moderation might reduce the risk of developing physical disability in older adults in good health but not in those in poor health.

Association between antihypertensive medication use and non-cardiovascular outcomes in older men

BACKGROUND

Antihypertensive drugs are prescribed commonly in older adults for their beneficial cardiovascular and cerebrovascular effects, but few studies have assessed antihypertensive drugs' adverse effects on non-cardiovascular outcomes in routine clinical practice.

OBJECTIVE

To evaluate, among older adults, the association between antihypertensive medication use and physical performance, cognition, and mood.

DESIGN AND SETTING

Prospective cohort study in a Veterans Affairs primary care clinic, with patients enrolled in 2000-2001 and assessed for medication use, comorbidities, health behaviors, and other characteristics; and followed-up 1 year later.

PARTICIPANTS

544 community-dwelling hypertensive men over age 65 years.

MEASUREMENTS

Timed chair stands; Trail Making Test part B; and Centers for Epidemiologic Studies Depression (CES-D) scores.

RESULTS

Participants had a mean age of 74.4 +/- 5.2 years and took a mean of 2.3 +/- 1.2 antihypertensive medications at baseline. After adjustment for age, comorbidities, level of blood pressure, and other confounders, each 1-unit increase in antihypertensive medication "intensity" was associated with a 0.11-second (95% confidence interval, 0.05-0.16) increase in the time required to complete the timed chair stands. No significant relationship was found between antihypertensive medication intensity and outcomes for Trail Making B or CES-D scores.

CONCLUSIONS

A higher cumulative exposure to antihypertensive medications in community-living older men was associated with adverse effects on physical performance, but not on the cognitive or depression measures available in this study. Clinicians should consider non-cardiovascular related adverse effects when treating older males taking multiple antihypertensive medications.

The role of medication use and health on the decision to quit drinking among older adults

OBJECTIVE

To determine the extent to which changes in medication use and health influence the decision to quit drinking among older adults.

METHOD

The sample consisted of 8,883 elderly enrolled in Pennsylvania's Pharmaceutical Assistance Contract for the Elderly (PA-PACE) program who completed surveys in 2000 and 2002. Survey data were linked with prescription claims to examine medication and health factors associated with drinking cessation between baseline and follow-up.

RESULTS

Overall, 3.9% of those using alcohol at baseline quit drinking during the study period. Logistic regression results showed that individuals who initiated antipsychotic (OR = 2.92) and antineoplastic therapies (OR = 2.67) were the most likely to quit drinking.

DISCUSSION

These findings support the hypothesis that elderly quit drinking in response to ill health. Results have implications for alcohol interventions in older adults and underscore the importance of separating former drinkers from lifetime abstainers in the study of alcohol-health relationships.

Moderate consumption of Cabernet Sauvignon attenuates Abeta neuropathology in a mouse model of Alzheimer's disease

Recent studies suggest that moderate red wine consumption reduces the incidence of Alzheimer's disease (AD) clinical dementia. Using Tg2576 mice, which model AD-type amyloid beta-protein (Abeta) neuropathology, we tested whether moderate consumption of the red wine Cabernet Sauvignon modulates AD-type neuropathology and cognitive deterioration. The wine used in the study was generated using Cabernet Sauvignon grapes from Fresno, California, and was delivered to Tg2576 in a final concentration of approximately 6% ethanol. We found that Cabernet Sauvignon significantly attenuated AD-type deterioration of spatial memory function and Abeta neuropathology in Tg2576 mice relative to control Tg2576 mice that were treated with either a comparable amount of ethanol or water alone. Chemical analysis showed the Cabernet Sauvignon used in this study contains a very low content of resveratrol (0.2 mg/L), 10-fold lower than the minimal effective concentration shown to promote Abeta clearance in vitro. Our studies suggest Cabernet Sauvignon exerts a beneficial effect by promoting nonamyloidogenic processing of amyloid precursor protein, which ultimately prevents the generation of Abeta peptides. This study supports epidemiological evidence indicating that moderate wine consumption, within the range recommended by the FDA dietary guidelines of one drink per day for women and two for men, may help reduce the relative risk for AD clinical dementia.

Association Between Change in Systolic Blood Pressure and Cognitive Decline Among Elderly Mexican Americans: Data from the Hispanic Established Population for Epidemiology Study of the Elderly

The longitudinal association between the rate of change in blood pressure and cognitive decline was examined in an area probability sample from a population-based survey of elderly Mexican Americans, 65 years of age or older obtained in 1993--1994, 1995--1996, 1998--1999, and 2000--2001 (n = 2859). The sample was divided into two groups at baseline: hypertensives had a systolic blood pressure (SBP) > or = 140 mm Hg, a diastolic blood pressure (DBP) > or = 90 mm Hg, or indicated a prior diagnosis of hypertension, and the normotensive group. Cognition was indexed by the Mini-Mental State Examination (MMSE). Neither SBP nor DBP at baseline predicted cognitive decline. However, the mean slope for SBP in the normotensive group showed an increase of 4.55mm Hg (increase from Time 1 to Time 2 was 123mm Hg to 132 mm Hg) and was significant in a regression model predicting cognitive decline even after adjusting for covariates. These findings suggest an association between increasing SBP and cognitive decline for normotensive elderly in this study population.

Health practices that predict recovery from functional limitations in older adults

BACKGROUND

Although previous studies show the benefits of certain health behaviors in reducing physical disability in older people, their effects on functional limitation, an antecedent of disability, are not well established. This study aims to identify health behavioral practices that affect recovery from functional limitations in older adults.

METHODS

A total of 312 community-dwelling adults aged 65 and older with functional limitations were examined in 2002 for functional recovery in 2003. Functional limitations were measured by self-reports of difficulty performing upper- and lower-body movements. Positive health practices included regular physical activity, normal body mass index (BMI), periodic medical checkups, and moderate alcohol consumption. Logistic regression models were fitted to identify individual as well as combined health practices that predict functional recovery, adjusting for sociodemographic and health-related covariates.

RESULTS

Although each of the positive health practices was significantly associated with functional recovery in the bivariate analyses, only physical activity continued to be a strong independent predictor in the multivariate analysis. The likelihood of functional recovery tended to increase with the number of health practices adopted by the elderly. Physical activity, in combination with normal BMI, proved to be one of the most influential health practice profiles, resulting in a high percentage of functional recovery.

CONCLUSIONS

Health behaviors, especially physical activity, contribute to an older person's functional independence. The benefit of an increased number of health practices on recovery from functional limitations suggests that targeting multiple behavioral risks may help delay the onset of disability in later life.

Light to moderate alcohol consumption is associated with better cognitive function among older male veterans receiving primary care

Among older persons, the effects of light to moderate alcohol consumption on cognitive function remain inadequately defined. The authors sought to determine whether light to moderate drinking is associated with better cognitive function among older men. Participants included men aged 65 years or older enrolled in a Veteran's Administration (VA) primary care clinic. Current (past 1 year) and lifetime use, cognitive functioning (as determined by the Trail Making Part B, Symbol Digit, FAS, and Hopkins Verbal Learning tests), and demographic, psychosocial, and medical status were obtained using standardized methods. Participants (N = 760) had a mean age of 74 (range, 65-89) years. Current drinkers (n = 509) as compared with never (n = 31) and former (n = 220) drinkers demonstrated significantly better cognitive performance on 3 (Trails B, Symbol Digit, and Hopkins Verbal Learning) of the 4 tests (P < .01 for all comparisons). In multiple linear regression models, current light to moderate drinking (ie, 7 or fewer drinks per week), as compared to a reference group of never and former drinkers, was associated with better performance on the Trails B, Symbol Digit, and Hopkins Verbal Learning tests (P < .01 for all comparisons). The number of years drinking 7 or fewer drinks per week also was independently associated with better cognitive performance. Current consumption of 7 or fewer drinks per week and the number of years drinking at this level are both associated with better cognitive performance in older male veterans receiving primary care. These findings are consistent with the hypothesis that light to moderate drinking confers cognitive benefits to older persons.

Older males, cognitive function, and alcohol consumption

We investigated the question, how do older men who drink alcohol differ from those who do not drink on measures of cognitive function, memory, affect, and health? Of the nonprobability sample of male participants (N = 60), 35 (58%) of the males reported some degree of alcohol consumption. Eleven men had one or more drinks per day, 14 had one or more drinks per week, and 9 were occasional drinkers. The drinkers reported significantly less depression, had higher self-reported general health and vitality, and had higher cognitive performance, cognitive flexibility, and verbal memory, and greater knowledge of memory processes.

Longitudinal patterns and predictors of alcohol consumption in the United States

OBJECTIVES

We examined demographic predictors of longitudinal patterns in alcohol consumption.

METHODS

We used mixed-effects models to describe individual alcohol consumption and change in consumption with age, as well as the associations between consumption and birth year, national alcohol consumption, and demographic factors, among 14 105 adults from the National Health and Nutrition Examination Survey I Epidemiologic Follow-Up Study.

RESULTS

Alcohol consumption declined with increasing age, and individual consumption mirrored national consumption. Higher consumption was associated with male gender, being White, being married, having a higher educational level, having a higher income, being employed, and being a smoker. Faster age-related decline in consumption was associated with earlier cohorts, being male, being married, having a lower educational level, and being a smoker.

CONCLUSIONS

Compared with alcohol consumption among earlier cohorts, that among recent cohorts declined more slowly with increasing age, suggesting that negative health effects of alcohol could increase in the future.
