Alcohol as a risk factor for fall injury events among elderly persons living in the community

Levels of vitamin D and a bone resorption marker in the sera of young women with alcohol use disorder

BACKGROUND

Excessive alcohol drinking negatively affects bone metabolism and leads to a risk of decreased bone mass, which is a major component of the pathogenesis of osteoporosis. However, the potential influence of alcohol on bones has not been fully recognized, particularly among the young to middle-aged generation.

OBJECTIVES

This study aimed to investigate the status of serum markers related to bone metabolism in young to middle-aged women with alcohol use disorder (AUD).

METHODS

Levels of vitamin D and the bone-resorption marker tartrate-resistant acid phosphatase 5b were measured in the sera of 25 women with AUD (mean age, 39.5 ± 7.5 years) who were enrolled in an AUD rehabilitation program. Data of samples obtained on admission and those after eight weeks were compared.

RESULTS

Of the 25 women with AUD, 19 (76%) had vitamin D deficiency (<20 ng/mL), and most of the patients showed relatively higher tartrate-resistant acid phosphatase 5b levels at baseline considering their premenopausal age. Although the levels did not change significantly at week eight of the AUD rehabilitation program, vitamin D levels tended to increase initially in patients with vitamin D deficiency. Although further investigations and detailed nutritional assessment are necessary, the results of this study may support the presence of a relatively unknown influence of AUD on the bone health of the young to middle-aged population. Along with psychological and physical care, persons with AUD should be treated as a high-risk group for future osteoporosis regardless of age.

Association between usual alcohol consumption and risk of falls in middle-aged and older Chinese adults

Background

Previous studies exploring usual alcohol consumption and falls risk were scarce in China. In addition, the dose–response relationship has not been explored so far. This study aims to estimate the association between usual alcohol consumption and risk of falls among middle-aged and older Chinese adults based on data from the China Health and Retirement Longitudinal Study (CHARLS), which is representative of the population of the entire country.

Methods

Baseline survey data in 2015 and follow-up data in 2018 in CHARLS were utilized. Alcohol consumption was calculated in grams per day (gr/day) according to self-reported drinking data and categorized accordingly to The Dietary Guidelines for Chinese Residents (DGC) 2016. Fall was obtained from self-reported information. Multivariable logistic regression analyses were performed to estimate the association of usual alcohol consumption with risk of falling. The dose–response relationship was also explored using restricted cubic splines.

Results

A total of 12,910 middle-aged and older participants were included from the CHARLS 2015, of which 11,667 were followed up in 2018. We found that former, moderate, and excessive drinkers were at higher fall risk compared to never drinkers (former: OR, 1.24; 95% CI, 1.05–1.46; moderate: OR, 1.22; 95% CI, 1.06–1.41; excessive: OR, 1.36; 95% CI, 1.15–1.61) in the longitudinal analysis. Similarly, individuals with moderate and excessive alcohol consumption were at increased risk of falling in the cross-sectional analysis (moderate: OR, 1.18; 95% CI, 1.02–1.37; excessive: OR, 1.32; 95% CI, 1.11,1.57). No significant increased risk of falls was found for former drinkers (former: OR, 1.13; 95% CI, 0.96–1.34). We observed a significant non-linear relationship.

Conclusions

Our study suggests that usual alcohol consumption was associated with a higher risk of falls, highlighting the key role of alcohol intake on the fall risk, which needed consideration in developing intervention and prevention strategies for reducing falls among middle-aged and older Chinese adults.

Epidemiology of at-risk alcohol use and associated comorbidities of interest among community-dwelling older adults: a protocol for a systematic review

INTRODUCTION

There is little epidemiological evidence and knowledge about at-risk alcohol use among community-dwelling older adults and their chronic and acute alcohol-related comorbidities of interest. This systematic review will summarise and examine relevant studies about the epidemiology of at-risk alcohol use and associated comorbidities of interest in this population.

METHODS

We will search the following databases, without language or date restrictions, from inception to 31 August 2019: Embase.com, Medline Ovid SP, Pubmed (NOT medline[sb]), CINAHL EBSCO, PsycINFO Ovid SP, Central-Cochrane Library Wiley and Web of Science (Core Collection). Search strategies will be developed in collaboration with a librarian. We will use predefined search terms for alcoholism, epidemiology, the elderly, living place and comorbidities of interest, as well as terms related to the identification of "measurements", "tools" or "instruments" for measuring harm from alcohol use. At-risk status will be determined by the amount of alcohol consumed and any comorbidities of interest associated with at-risk alcohol use, with the latter being documented separately or using an assessment tool for at-risk drinking. We will also examine the bibliographies of all the relevant articles found and search for unpublished studies. We will consider publications in all languages.

ETHICS AND DISSEMINATION

No ethical approval is necessary. Results will be presented in national and international conferences on addiction and published in a peer-reviewed journal.

Patterns of alcohol consumption and risk of falls in older adults: a prospective cohort study

Falls are a major health problem in older adults, but their relationship with alcohol consumption in this population remains unclear. In a cohort with 2170 older adults followed up for 3.3 years, both moderate drinking and the Mediterranean drinking pattern were associated with a lower risk of falls and injurious falls.

INTRODUCTION

This study aims to examine the association between certain patterns of alcohol consumption, including the Mediterranean drinking pattern (MDP), and the risk of falls in older adults.

METHODS

A prospective cohort with 2170 community-dwelling individuals aged ≥60 years was recruited in Spain in 2008-2010 and followed up through 2012. At baseline, participants reported alcohol consumption and, at the end of follow-up, their falls during the previous year. The MDP was defined as moderate alcohol consumption (threshold between moderate and heavy intake was 40 g/day for men and 24 g/day for women) with preference for wine and drinking only with meals. Analyses were conducted with negative binomial or logistic regression, as appropriate, and adjusted for the main confounders.

RESULTS

Compared with never drinkers, the number of falls was lower in moderate drinkers (incidence rate ratio (95% confidence interval), 0.79 (0.63-0.99)) and drinkers with MDP (0.73 (0.56-0.96)). Also, moderate drinkers and those with MDP showed a lower risk of ≥2 falls (odds ratio (95% confidence interval), 0.58 (0.38-0.88) and 0.56 (0.34-0.93), respectively) and of falls requiring medical care (0.67 (0.46-0.96) and 0.61 (0.39-0.96), respectively).

CONCLUSION

Both moderate drinking and the MDP were associated with a lower risk of falls and injurious falls in older adults. However, sound advice on alcohol consumption should balance risks and benefits.

Alcohol Consumption at Any Level Increases Risk of Injury Caused by Others: Data from the Study on Global AGEing and Adult Health

BACKGROUND

Alcohol use is a well-known risk factor for injury. However, information is needed about alcohol drinking patterns and the risk of injury among older adults in low- and middle-income countries as this population grows. We aimed to examine the influence of drinking patterns on the burden of injury and investigate factors associated with different types of injury in older populations in six emerging economies.

METHODS

Data from more than 37,000 adults aged 50 years and older were included from the Study on Global AGEing and Adult Health (SAGE) Wave 1 conducted in six emerging economies, namely, China, Ghana, India, Mexico, Russia, and South Africa. We investigated past-year reported injuries from falls, traffic accidents, and being hit or stabbed. Alcohol drinking patterns were measured as lifetime abstinence, ever but not past- week use, and gender-specific past-week low-risk and high-risk use. We stratified by gender and used logistic regression models to observe the association between alcohol drinking pattern and risk of injury by controlling for other factors.

RESULTS

During the year prior to interview, 627 (2.2%) subjects reported bodily injury resulting from a car accident, 1,156 (4.2%) from a fall, and 339 (0.9%) from being hit or stabbed during the past year. For women, only being a high-risk drinker increased the risk of being hit or stabbed, whereas for men, all levels of drinking were associated with an increased risk of being hit or stabbed. We observed a higher risk of being hit or stabbed from past-week high-risk drinking among women (odds ratio [OR] = 6.09, P < 0.01) than among men (OR = 3.57, P < 0.01). We observed no association between alcohol drinking pattern and injury due to car accidents for either women or men.

CONCLUSIONS

The risk of experiencing injury due to violence increased with level of alcohol exposure of the victim. The increase in alcohol use in emerging economies calls for further study into the consequences of alcohol use and for public health initiatives to reduce the risk of violence in older adult populations, with special attention to the experience of older adult women.

Prevalence and Determinants of Falls among Older Adults in Ecuador: An Analysis of the SABE I Survey

The present study based on a nationally representative sample of older adults living in the Andes mountains and coastal region of the country indicates that 34.7% of older adults had fallen in the previous year in Ecuador. Among fallers, 30.6% reported a fall-related injury. The prevalence of falls was higher in women and among older adults residing in the rural Andes mountains. In the multivariate model, women, subjects with cognitive impairment, those reporting urinary incontinence, and those being physically active during the previous year were variables found independently associated with increased risk of falling among older adults in Ecuador. Moreover, a gradual and linear increase in the prevalence of falls was seen as the number of risk factors increased. Falls represent a major public health problem among older adults in Ecuador. The present findings may assist public health authorities to implement programs of awareness and fall prevention among older adults at higher risk of falls.

Risk factors for falls and fall-related injuries in adults 85 years of age and older

Falls are a leading cause of morbidity and mortality in older adults. No previous studies on risk factors for falls have focused on adults 85 years and older, the most rapidly growing segment of adults. We examined demographic, health, and behavioral risk factors for falls and fall-related injuries in adults 65 years and older, with a particular focus on adults 85 years and older. We analyzed self-reported information from the Behavioral Risk Factor Surveillance System (BRFSS) for 2008. Data was available for 120,923 people aged 65 or older and 12,684 people aged 85 or older. Of those aged 85 or older, 21.3% reported at least one fall in the past 3 months and 7.2% reported at least one fall related injury requiring medical care or limiting activity for a day or longer. Below average general health, male sex, perceived insufficient sleep, health problems requiring assistive devices, alcohol consumption, increasing body mass index and history of stroke were all independently associated with a greater risk of falls or fall related injuries. The greater risk of falling in those 85 years and older appeared to be due to the deterioration of overall health status with age; among those with excellent overall health status, there was no greater risk of falling in adults 85 years and older compared to those 65-84 years of age. Our results suggest that those with risk factors for falls and fall-related injuries may be appropriate targets for evidence-based fall prevention programs.

Psychotropic Drugs and Falls in the Elderly People: Updated Literature Review and Meta-Analysis

Objective: To carry out meta-analyses on psychotropic drugs and to provide an update of the risk of falling in the elderly people related to psychotropic drugs. Design: Meta-analyses of studies on psychotropic drugs. Results: 177 studies are included, of which 71 have data on risk factors associated with psychotropic drugs. The odds ratio and 95% Cl for associations between use of psychotropic drugs and fall are 1.78 and 1.57-2.01, respectively. This result is statistically heterogeneous. This heterogeneity disappears in the group of very old participants for each class. Conclusion: Our study confirms the association between falls in the elderly people and psychotropic drugs. These results are similar to those of former meta-analyses but with different methods. It shows that these meta-analyses on psychotropic drugs have a small impact on prescribing habits. They only give evidence to support the association between psychotropic drugs and falls even if there is no proven link.

Episodes of falling among elderly people: a systematic review and meta-analysis of social and demographic pre-disposing characteristics

CONTEXT

The multifactorial nature of falls among elderly people is well-known. Identifying the social-demographic characteristics of elderly people who fall would enable us to define the typical profile of the elderly who are at risk of falling.

OBJECTIVE

We aimed to isolate studies in which the social-demographic risk factors for falls among the elderly have been evaluated and to carry out a meta-analysis by combining the results of all of these selected studies.

METHOD

We did a systematic literature review using the key words "accidental fall / numerical data" and "risk factors." Inclusion criteria entailed the selection of articles with the following characteristics: population of subjects aged 60 years or over, falls that took place in everyday life, and social-demographic risk factors for falls.

RESULTS

3,747 indexed articles published between 1981 and 2007 were identified, and 177 studies with available data were included, of which 129 had data on social-demographic risk factors for falls. Difficulties in activities of daily living (ADL) or in instrumental activities of daily living (IADL) double the risk of falling: The OR and 95% Cl were 2.26 (2.09, 2.45) for disturbance ADL and 2.10 (1.68, 2.64) for IADL. The OR and 95% Cl for Caucasians were 1.68 (0.98 - 2.88) and 0.64 (0.51 - 0.80) for Hispanics. In the subgroup of patients older than eighty, being married protected people from falling with an OR and 95% Cl =0.68 (0.53 - 0.87).

CONCLUSION

Defining factors that create a risk of falling and protect elderly people from falls using social-demographic characteristics lets us focus on an "at risk" population for which a specific program could be developed.

The contribution of alcohol to falls at home among working-aged adults

The role of alcohol in the occurrence and burden of fall related injury at home is unclear. We examined the contribution of alcohol to fatal and hospitalized injuries due to unintentional falls at home among working-aged adults. We conducted a population-based case-control study in Auckland, New Zealand between July 2005 and July 2006. Cases were 335 people aged 25-60 years who were admitted to hospital or died as a result of unintentional falls at home. Control subjects were 352 people randomly selected from the electoral roll from the same age band as the cases. The participants or next-of-kin completed a structured interview that ascertained data on sociodemographic, personal, and lifestyle factors including alcohol consumption. After controlling for confounding, the consumption of two or more standard alcoholic drinks in the preceding 6h relative to none was associated with a significantly increased risk of fall related injury (for two standard drinks: odds ratio: 3.7, 95% confidence interval: 1.2-10.9; for three or more drinks: odds ratio: 12.9, 95% confidence interval: 5.2-31.9). Approximately 20% of unintentional falls at home in this population may be attributable to the consumption of two or more alcoholic drinks in the preceding 6h. Drinking is strongly associated with unintentional falls at home that result in admission to hospital or death. Moreover, a substantial proportion of falls at home among working-age people can be attributed to alcohol consumption. This largely unrecognized problem should be addressed in falls prevention programs.

Falls in the community-dwelling older adult: a review for primary-care providers

Falls in the elderly are an important independent marker of frailty. Up to half of elderly people over 65 experience a fall every year. They are associated with high morbidity and mortality and are responsible for greater than 20 billion dollars a year in healthcare costs in the United States. This article presents a review and guide for the primary care provider of the predisposing and situational risk factors for falls; comprehensive assessment for screening and tailored intervention; and discussion of single and multicomponent measures for fall prevention and management in the older person living in the community. Interventions for the cognitively impaired and demented elderly will also be addressed.

Circumstances and consequences of falls in community-dwelling older women

AIMS

To describe the circumstances and consequences of falls reported by community-dwelling older women.

METHODS

This prospective study collected data for approximately 2 years for women aged>or=70 years at risk for falling who were enrolled in the Fall Evaluation and Prevention Program.

RESULTS

Participants (263) completed a median of 24 months of follow-up. A total of 143 participants reported 341 falls; 70 reported 1 fall, and 73 reported 2 or more. A majority of falls (62%) occurred in/around the home, primarily during the daytime, and in living rooms or kitchens/dining rooms. Falls frequently occurred while walking, carrying objects, or reaching/leaning. Many falls did not result in injury (53%); however, 31% resulted in minor injuries, 10% in moderate injuries, and 6% in major injuries. Soft tissue injuries were common, and 5% of falls resulted in fractures. Nine falls resulted in hospitalization.

CONCLUSIONS

The high rate of injurious falls seen here and the detailed information on activity at the time of the fall emphasize the need to increase awareness of behaviors and the environment to reduce fall risk. Previous studies have identified risk factors for falls, some of which cannot be modified, such as age or gender. In contrast, this study describes the activity at the time of the fall: many falls occur in the home environment, some with modifiable circumstances.

Alcohol consumption, bone density, and hip fracture among older adults: the cardiovascular health study

INTRODUCTION

Previous studies have found inconsistent relationships of alcohol consumption with risk of hip fracture, and the importance of bone mineral density and risk of falls in mediating such a relationship has not been determined.

METHODS

As part of the Cardiovascular Health Study, a population-based cohort study of adults aged 65 years and older from four U.S. communities, 5,865 participants reported their use of beer, wine, and liquor yearly. We identified cases of hip fracture unrelated to malignancy or motor vehicle accidents using hospitalization discharge diagnoses. A subgroup of 1,567 participants in two communities underwent dual-energy x-ray absorptiometry scans to assess bone mineral density.

RESULTS

A total of 412 cases of hip fracture occurred during an average of 12 years of follow-up. There was a significant U-shaped relationship between alcohol intake and risk of hip fracture (p quadratic 0.02). Compared with long-term abstainers, the adjusted hazard ratios for hip fracture were 0.78 (95% confidence interval [CI], 0.61-1.00) among consumers of up to 14 drinks per week and 1.18 (95% CI, 0.77-1.81) among consumers of 14 or more drinks per week. Alcohol intake was associated with bone mineral density of the total hip and femoral neck in a stepwise manner, with approximately 5% (95% CI, 1%-9%) higher bone density among consumers of 14 or more drinks per week than among abstainers. These relationships were all similar among men and women.

CONCLUSIONS

Among older adults, moderate alcohol consumption has a U-shaped relationship with risk of hip fracture, but a graded positive relationship with bone mineral density at the hip.

Alcohol-drinking history and fatal injury in older adults

Although most clinical guidelines for older adults allow for one drink a day in persons without a history of alcoholism, diabetes, or cardiovascular disease, alcohol may contribute to fatal injury in the elderly. Using two national surveys, this case-control study determined the associations between drinking history and fatal injuries from falls, motor vehicle crashes and suicides. We performed a case-control study using 1,735 cases who died of falls, motor vehicle crashes, or suicides selected from the 1993 National Mortality Follow-Back Survey; controls (n=13,381) were a representative sample of the U.S. population from the 1992 National Longitudinal Alcohol Epidemiologic Survey. Cases and controls were restricted to ages 55 years and older. Having 12 or more drinks in the year before death or interview for the controls was used to assess alcohol-drinking history. The unadjusted relative odds for drinkers versus nondrinkers for falls, motor vehicle crashes, and suicides were 1.7, 1.7, and 1.6, respectively. Adjustment for age, gender, marital status, education, and working in the last year did not change these effect estimates, which all excluded the null value. Drinking increased the risk of suicide more for women than for men. Drinking history in older adults is associated about equally with an increased risk of fatal injury from falls, motor vehicle crashes, and suicides.

Alcohol Intake and Its Relationship with Bone Mineral Density, Falls, and Fracture Risk in Older Men

OBJECTIVES

To examine the association between alcohol intake and problem drinking history and bone mineral density (BMD), falls and fracture risk.

DESIGN

Cross-sectional and prospective cohort study.

SETTING

Six U.S. clinical centers.

PARTICIPANTS

Five thousand nine hundred seventy-four men aged 65 and older.

MEASUREMENTS

Alcohol intake and problem drinking histories were ascertained at baseline. Follow-up time was 1 year for falls and a mean of 3.65 years for fractures.

RESULTS

Two thousand one hundred twenty-one participants (35.5%) reported limited alcohol intake (<12 drinks/y); 3,156 (52.8%) reported light intake (<14 drinks/wk), and 697 (11.7%) reported moderate to heavy intake (> or =14 drinks/wk) in the year before baseline. One thousand one men (16.8%) had ever had problem drinking. In multivariate models, as alcohol intake increased, so did hip and spine BMD (P for trend < .001). Greater alcohol intake was not associated with greater risk for nonspine or hip fractures. Men with light intake, but not moderate to heavy intake, had a lower risk of two or more incident falls (light intake: relative risk (RR) = 0.77, 95% confidence interval (CI) = 0.65-0.92; moderate to heavy intake: RR = 0.83, 95% CI = 0.63-1.10) than abstainers. Men with problem drinking had higher femoral neck (+1.3%) and spine BMD (+1.4%), and a higher risk of two or more falls (RR = 1.59; 95% CI = 1.30-1.94) than those without a history of problem drinking and similar total hip BMD and risk of fracture.

CONCLUSION

In older men, recent alcohol intake is associated with higher BMD. Alcohol intake and fracture risk is unclear. Light alcohol intake may decrease the risk of falling, but a history of problem drinking increased fall risk.

What is the role of falls?

There is now firm evidence to support interventions in the prevention of falls in older people, and emerging data support prevention of falls as a method of fracture prevention. This chapter discusses the epidemiology of falls, risk factors associated with an increased risk of falling, assessment of the older faller, and evidence-based approaches to the prevention of falls in the older person. Several randomized controlled trials have found that hip protectors, if worn, probably prevent hip fractures, but that poor compliance is a major issue limiting the effectiveness of this form of intervention. More data are needed to support the role of prevention of falls in preventing fractures, as well as comparative cost-effectiveness data with other evidence-based approaches to preventing fractures in an older population.

Risk factor for accidental injuries within senior citizens' homes: analysis of the Canadian Survey on Ageing and Independence

Using data from the Survey on Ageing and Independence (SAI), risk factors for unintentional injuries occurring within the homes of individuals older than 65 are identified. For the SAI, conducted by Statistics Canada in 1991, data were collected on a representative sample of approximately 20,000 individuals between ages 45 and 102. For each household contacted, one individual older than 45 was interviewed via the telephone. For the present analysis, only individuals older than 65 (n = 10,059) were used. Approximately 5% of senior citizens experienced an injury that limited their activity for at least 1 day. Using logistic regression, the following risk factors for injury were identified: education, alcohol consumption, smoking, rest and sleep patterns, support, and interactions between age and gender, activity limitations and age, and home maintenance and gender. The present findings are important to the body of research concerning injuries among older adults. The results expand current univariate analysis of data identifying risk factors for injuries within the literature and provide comprehensive information pertaining to risk factors for accidental injuries at the multivariate level. Identification of risk factors provides health care professionals, particularly front line nurses, with insight into factors that, if modified, have the potential to decrease accidental injuries and improve or maintain quality of life.

Correlates of falling during 24 h among elderly Danish community residents

OBJECTIVES

To identify dietary, medical, and environmental correlates of falling during the last 24 h among elderly community residents. The limited accuracy of recall of falls in the elderly in previous studies was the reason for a 24-h time frame.

METHODS

The study composes 4281 community residents aged 66+ years. The statistical analyses included Pearson's chi(2) test and multiple logistic regression.

RESULTS

Mutually independent correlates of falls were a family history of fracture (OR, 3.0; 95% CI: 1.3-7.1); osteoarthrosis of the knee (OR, 2.9; 95% CI: 1.3-6.2); dizziness (OR, 4.1; 95% CI: 1.9-8.9); a diet not including sour dairy products (OR, 3.0; 95% CI: 1.4-6.3) or fish (OR, 3.4; 95% CI: 1.5-7.5); drinking tea (OR, 5.8; 95% CI 2.15-15.30); needing help for shopping (OR, 3.9; 95% CI: 1.6-9.3); and for administration of medicine (OR, 9.0; 95% CI: 2.0-40.6). Independent environmental correlates were vinyl on the floor in the bathroom (OR, 6.6; 95% CI: 2.1-20.9) and using indoor footwear without soles (OR, 5.5; 95% CI: 2.3-13.4).

CONCLUSION

The present analyses suggest that several factors are associated to the risk of falling among elderly community residents. It appears relevant for further studies to test if modifications of the potential risk factors identified may reduce falls among community dwelling older persons.

Self-Reported Alcohol Consumption and Falls in Older Adults: Cross-Sectional and Longitudinal Analyses of the Cardiovascular Health Study

OBJECTIVES

To assess the cross-sectional and longitudinal associations between alcohol consumption and risk of falls in older adults.

DESIGN

Cross-sectional and longitudinal analyses.

SETTING

Four U.S. communities.

PARTICIPANTS

A total of 5,841 older adults enrolled in the Cardiovascular Health Study, an ongoing, population-based, prospective cohort study, participated.

MEASUREMENTS

Self-reported alcohol consumption at baseline, self-reported frequent falls at baseline, and the 4-year risk of falls of participants who denied frequent falls at baseline.

RESULTS

Cross-sectional analysis indicated an apparent inverse association between alcohol consumption and risk of frequent falls (adjusted odds ratio in consumers of 14 or more drinks per week=0.41; 95% confidence interval (CI)=0.14-1.17; P for trend=.06), but longitudinal analysis indicated a similar 4-year risk of falls in abstainers and light to moderate drinkers but a 25% higher risk in consumers of 14 or more drinks per week (95% CI=3-52%; P for trend=.07). Similar results were found in analyses stratified by age, sex, race, and physical activity.

CONCLUSION

Consumption of 14 or more drinks per week is associated with an increased risk of subsequent falls in older adults. Cross-sectional studies may fail to identify this risk of heavier drinking, perhaps because older adults at risk for falls decrease their alcohol use over time or because heavier drinkers at risk for falls tend not to enroll in cohort studies. However, because this study relied upon annual reporting of falls, further prospective studies should be conducted to confirm these findings.

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

Increased alcohol consumption is associated with substantial morbidity and mortality in young and middle-aged adult populations, but its effects on the health of older adults have received less attention. The objective of the study was to review published studies that assessed the effects of alcohol on falls or fall injuries, functional impairment, cognitive impairment, and all-cause mortality among older adults. MEDLINE database and bibliographies of selected citations were searched for English language studies published between 1966 and 1998 that examined the relationship between alcohol and one or more of the above outcomes. Also a study was analyzed if it included participants 60 years of age or older, or a broader age range of participants and reported results for older subgroups, or predominantly older participants as evidenced by a mean age of 65 years of age or above. Information on studies' sample sizes, exposure and outcome measures, and risk estimates were extracted, and articles were evaluated for methodologic quality using predetermined criteria. Eighty-four studies were identified that examined 91 potential exposure-outcome associations including falls or fall injuries (n = 26); functional impairment (n = 13); cognitive impairment (n = 32); and all-cause mortality (n = 20). The percentage of studies demonstrating harm, no association, or benefit by outcome included falls (15% vs. 81% vs. 4%); functional disability (38% vs. 46% vs. 16%); cognitive impairment (31% vs. 66% vs. 3%); and all-cause mortality (15% vs. 65% vs. 20%). Studies (n = 84) inconsistently adhered to methodologic standards. Although 90% provided eligibility criteria; 61% cited participation rates; and 73% described the methods used to measure alcohol exposure; only 44% adjusted for potentially important confounding factors; and 26% distinguished former drinkers from nondrinkers. Of the cohort studies (n = 47), 30% assessed for change in participants' exposure status over time, and 17% determined whether losses to follow-up varied by exposure status. The magnitude of risk posed by alcohol use for falls or fall injuries, functional disability, cognitive impairment, and all-cause mortality among older adults remains uncertain. Prospective studies are needed to better define the health-related effects of alcohol use in older populations.

Oral care for successful aging in long-term care

The oral health of frail elders residing in long-term care facilities is very poor, probably because access to dental services is limited and help with daily mouth care is almost nonexistent. Recent concerns and interest have been raised through the cooperation of administrators, nursing staff, and dental personnel to address this apparent neglect. Moreover, evidence shows that caries and periodontal disorders can be managed successfully in geriatric populations. Consequently, there is a basis on which to develop a practical strategy for mouth care that should reduce the morbidity and early mortality in long-term care and to assist an increasingly frail and dependent population to age successfully.

Alcohol use in late life: disability and comorbidity

Alcohol use by older adults is common, yet the risks and/or benefits of drinking, especially moderate drinking, are not well understood. Heavy drinking is a well-established factor in causing disability and excessive mortality among all age groups, including the elderly. However, literature is emerging that suggests that among elders with chronic medical and emotional health disorders, even modest alcohol consumption can lead to excessive disability and poorer perceived health. This article reviews the current literature on alcohol use and the relationship to common health problems in late life and suggests a model for examining the interaction of alcohol use and disability. Implications for intervention development are also discussed.

The effect of alcohol abuse on the health status of older adults seen in the emergency department

OBJECTIVE

To examine the effect of alcohol abuse on the subsequent health status of elderly patients seen in an emergency department (ED).

PATIENTS AND METHODS

A sample of 966 patients aged 65 or older who presented to one urban academic ED between the hours of 8 A.M. and 12 midnight was followed for 1 year. A personal interview was administered during the ED visit. Current problem drinkers had a score of 1 or greater on the CAGE questionnaire at ED presentation and drank within the prior 6 months; former problem drinkers had a score of 1 or greater on the CAGE questionnaire at ED presentation and a last drink more than 6 months previously. We used 13 items from the Medical Outcomes Study short form adapted to the ED setting and 6 items from the Index of Activities of Daily Living (ADL) to measure health status.

RESULTS

In multivariate models for repeated-measures controlling for potential confounding factors, current problem drinkers had worse overall health (parameter estimate beta -3.6; 95% CI -7.1 to -0.04), and former problem drinkers had worse mental health (beta -3.6; CI -6.9 to -0.24) on follow-up. We could find no effect of problem drinking on physical health or social function.

CONCLUSIONS

Current problem drinking is associated with worse self-perceived health among elderly patients in the year following presentation to an ED. The magnitude of decline in health perception may approximate the effect of having back pain, sciatica, or other musculoskeletal complaints. Elderly former problem drinkers suffer from more severe mental health problems over that same period.

Medical risks for women who drink alcohol

OBJECTIVE

To summarize for clinicians recent epidemiologic evidence regarding medical risks of alcohol use for women.

METHODS

MEDLINE and PsychINFO, 1990 through 1996, were searched using key words "women" or "woman," and "alcohol." MEDLINE was also searched for other specific topics and authors from 1980 through 1996. Data were extracted and reviewed regarding levels of alcohol consumption associated with mortality, cardiovascular disease, alcohol-related liver disease, injury, osteoporosis, neurologic symptoms, psychiatric comorbidity, fetal alcohol syndrome, spontaneous abortion, infertility, menstrual symptoms, breast cancer, and gynecologic malignancies. Gender-specific data from cohort studies of general population or large clinical samples are primarily reviewed.

MAIN RESULTS

Women develop many alcohol-related medical problems at lower levels of consumption than men, probably reflecting women's lower total body water, gender differences in alcohol metabolism, and effects of alcohol on postmenopausal estrogen levels. Mortality and breast cancer are increased in women who report drinking more than two drinks daily. Higher levels of alcohol consumption by women are associated with increased menstrual symptoms, hypertension, and stroke. Women who drink heavily also appear to have increased infertility and spontaneous abortion. Adverse fetal effects occur after variable amounts of alcohol consumption, making any alcohol use during pregnancy potentially harmful.

CONCLUSIONS

In general, advising nonpregnant women who drink alcohol to have fewer than two drinks daily is strongly supported by the epidemiologic literature, although specific recommendations for a particular woman should depend on her medical history and risk factors.

Alcohol and injuries in elderly people

Injuries are a common cause of morbidity and mortality among elderly people. Falls are the most common type of accident, accounting for around 40% of injuries. There is substantial evidence that heavy alcohol use is an important risk factor for injuries in younger people, but results of the few studies of alcohol and injuries among elderly people have been inconsistent. In this paper, we review the literature on the effects of alcohol on gait and balance and present reasons that a causal relationship between alcohol and injuries is biologically plausible. We review the epidemiological studies of the relationship between alcohol and falls, hip fractures and other injuries in the elderly population and discuss sources of error in these studies. Selection bias, small sample sizes, measurement error and potential confounders such as age, gender, health status and medications may have played a substantial role in negative results from several studies. Further research that will help clarify the relationship between alcohol and injuries in elderly people is sorely needed.

Menopause

The area of menopausal medicine is undergoing rapid evolution as millions of baby boomers enter this life stage. This group came of age at a time when all cultural values and institutions, including the basic assumptions underlying the healthcare of women, underwent intense scrutiny. As a result, alternative approaches to everything from childbirth to menopause have become increasingly mainstream. This article gives the healthcare provider both the philosophical background and practical solutions necessary to assist the menopausal woman in choosing an individualized program to minimize her risk for disease and maximize her postmenopausal health potential by combining the best of both conventional and alternative medical approaches.

Geriatric substance use disorders

AUDs are increasingly recognized as common problems among older adults. The magnitude of this problem is likely to increase over ensuing decades as baby boomers reach retirement age with drinking habits that are significantly different from current cohorts of older adults. Barriers to detection are numerous and include nonspecificity of alcohol-related presentations, patient denial, and clinicians' unwillingness to recognize that patients can and do develop alcohol problems in later life. Despite the limitations of current screening and diagnostic instruments, the authors recommend use of the CAGE as a formal screening tool for older patients because of its brevity, demonstrated efficacy, and convenience. In patients who answer affirmatively to any CAGE question, diagnostic certainty can be increased by use of follow-up questions or referral to an alcohol treatment specialist. Referral of patients with established alcohol abuse or dependence is essential for definitive treatment, and successful outcomes can be expected and are gratifying once achieved. In patients with less severe AUDs, brief interventions with frequent follow-up are recommended. Age-specific screening and diagnostic instruments for older AUD patients, once fully developed and validated, will facilitate identification. Much less is known about other substance use disorders in older adults. Psychoactive drug use is not uncommon in this patient population and may result in adverse health outcomes. Treatment interventions proposed for AUDs are advocated for older adults found to have other substance use disorders as well and are likely to yield improved outcomes. Future investigations that better define the epidemiology, detection, and treatment of other substance use disorders in older populations are clearly warranted at this time.

Risk factors for injuries among the elderly in Greece

Extrinsic and intrinsic risk factors for injuries among the elderly in Greece were investigated in a hospital based case-control study. Cases were 200 elderly persons, residents of the Greater Athens area, who contacted the "Laiko" University Hospital for accident-related injuries, during a 10-month period, whereas the control series comprised 385 elderly who, during the same period, contacted the same hospital for non-injury related medical reasons. Data were analyzed by modeling through multiple logistic regression. Statistically significant associations were found for smoking vs non-smoking [odds ratio (OR) 2.40; 95% confidence interval (CI) 1.22-4.70], moderate use of alcoholic beverages vs non use (OR 0.37; CI 0.23-0.61) and house safety score (OR 0.72; CI 0.56-0.93 for an improvement by 1 unit). Non statistically significant positive associations were noted with history of previous hospitalizations for injury, chronic central nervous system conditions, defective hearing, refractive eye disorders, current use of psychoactive drugs, excessive use of alcoholic beverages, other than ground floor residency, cohabitation with fewer members and other than currently married status. Restricted activity was assessed in subsamples of cases and controls and was associated with somewhat reduced risk for injury (OR for one unit increase in a 10 unit modified Groningen activity scale is 1.06; CI 0.99 to 1.13). Overall, these results suggest that there is a constellation of plausible risk factors for injuries among the elderly.

Current use of thiazide diuretics and prevention of femur fractures

A case control study of a defined population from The Netherlands was performed to evaluate the risk of femur fractures associated with the use of thiazide diuretics. Included were 386 patients hospitalized for femur fractures between 1986 and 1990 who were residents and 45 years of age and older. Per case, one age-, sex-, pharmacy-, and general practitioner-matched control was chosen from the general population. Drug use was ascertained from computerized pharmacy records. The adjusted odds ratio of current use of thiazide diuretics was 0.5 (95% confidence interval, 0.3-0.9). The protective effect of thiazide diuretics was greatest for use of 1 year or longer at relatively high doses of thiazides (odds ratio, 0.3; 95% confidence interval, 0.1-0.9). We also found that patients who discontinued thiazide use longer than 2 months were not protected against femur fractures. These results support the hypothesis that use of thiazide diuretics protects against femur fractures.

Psychoactive medication, alcohol use, and falls among older adults

The purposes of this study were to determine: (1) the prevalence of psychoactive medication and alcohol use and (2) the relationship among psychoactive medications, alcohol use, and falls in a sample of 1028 independently living women and men, aged 55 and older. Twenty-six percent of the sample reported falling, 28% were taking one or more psychoactive drugs, and 38% drank alcohol during the past year. Analyses with logistic regression indicate that predictors of falls were psychoactive drug use, age, and number of illnesses. Living alone, frequency of alcohol use, and gender were not significant predictors.

Management of trauma in the elderly patient

Injuries among the elderly are a common occurrence and, as the population ages, the elderly will constitute a prominent proportion of trauma patients. The elderly sustain the same injuries that younger people do; however, because of a variety of age-related processes, the elderly suffer more severe consequences from these injuries. Epidemiologic factors and physiologic processes are used to explain the "susceptibility" of the elderly population to traumatic injuries. Recommendations for initial resuscitation and management of specific injuries are presented along with general principles of injury prevention and rehabilitation. The socioeconomic cost of trauma in the elderly is discussed in terms of physical disabilities and financial burdens.

Diagnosis and assessment of substance abuse in older adults: current strategies and issues

Alcohol and substance abuse in older adults until recently has received little empirical attention in the literature. However, in light of the increasing number of older adults in the population, clinicians and researchers alike are recognizing the importance of evaluating specific assessment and treatment strategies for such older substance abusers. Because distinctive biological, cognitive, and psychosocial variables appear to be correlated with substance abuse in older adults, evaluation and intervention methods employed with younger cohorts may be inappropriate or ineffective with individuals 55 and over. Our article, therefore, examines these characteristics as they pertain to the unique problems and service needs of the elderly. Relevant diagnostic and assessment strategies are reviewed. Finally, suggestions for future work in this area are outlined.

Genetic susceptibility and head injury as risk factors for Alzheimer's disease among community-dwelling elderly persons and their first-degree relatives

We performed a community-based study to investigate the relationship of genetic susceptibility and head injury to Alzheimer's disease (AD) in 138 patients with AD and 193 healthy elderly control subjects. Data concerning presence or absence of dementia and certain exposures were also obtained from 799 first-degree relatives of the patients and 1,238 first-degree relatives of the control subjects. Adjusting for age, gender, and other risk factors, the odds ratio for AD associated with head injury was 3.7 (95% confidence interval [CI], 1.4-9.7). The association was highest for head injuries that occurred after age 70. The risk of AD was higher in first-degree relatives of patients with onset prior to age 70 than in relatives of control subjects (risk ratio [RR] = 2.5; 95% CI, 1.1-5.6). The risk was not increased for relatives of patients with onset of AD at age 70 or older. Compared with relatives without head injury, the risk of AD was increased among both head-injured relatives of patients (RR = 5.9; 95% CI, 2.3-14.8) and head-injured relatives of control subjects (RR = 6.9; 95% CI, 2.5-18.9). Our results are consistent with the hypothesis that severe head injury and genetic susceptibility are associated with AD. Both associations concur with current concepts regarding the role of amyloid in AD. Although we regard head injury, like genetic susceptibility, to be a putative risk factor for AD, the temporal relationship between head injury and AD warrants further investigation.

Alcohol abuse in elderly emergency department patients

OBJECTIVES

To determine the prevalence of alcohol abuse in elderly emergency department (ED) patients; to determine the prevalence of alcohol abuse for various categories of illness and injury among these patients; and to determine the frequency of detection of elderly alcohol abusers by ED physicians.

DESIGN

Cross-sectional prevalence study.

SETTING

The emergency department of a 625-bed university hospital that serves a mixed urban and rural population.

PATIENTS

205 patients aged 65 and over who came to the ED during an 8-week period.

MEASURES

A structured interview, which included the CAGE questionnaire and other questions regarding alcohol use, was administered. Emergency department records and past medical records were reviewed.

RESULTS

The prevalence of lifetime alcohol abuse (CAGE positive or self-reported drinking problem) was 24%. The prevalence of current alcohol abuse (CAGE positive or self-reported drinking problem and alcohol use within the last year) was 14%. There was a particularly high prevalence (22%) among those presenting with gastrointestinal problems and a surprisingly low prevalence (7%) among those who presented with falls or other trauma. Physicians detected only 21% of the current alcohol abusers.

CONCLUSIONS

Alcohol abuse is a prevalent and important problem among elderly ED patients. It is not well detected by physicians in this setting. Alcohol abuse appears to be less common among elderly trauma patients than their younger counterparts, but is very common among patients with gastrointestinal problems.
