Descriptors of alcohol consumption among noninstitutionalized nonalcoholic elderly

Moderate alcohol intake and risk of functional decline: the Health, Aging, and Body Composition study

OBJECTIVES

To investigate the prospective relationship between alcohol consumption and incident mobility limitation.

DESIGN

Cohort study.

SETTING

The Health Aging and Body Composition study, conducted in Memphis, Tennessee, and Pittsburgh, Pennsylvania.

PARTICIPANTS

Three thousand sixty-one adults aged 70 to 79 without mobility disability at baseline.

MEASUREMENTS

Incidence of mobility limitation, defined as self-report at two consecutive semiannual interviews of any difficulty walking one-quarter of a mile or climbing stairs, and incidence of mobility disability, defined as severe difficulty or inability to perform these tasks at two consecutive reports. Alcohol intake, lifestyle-related variables, diseases, and health status indicators were assessed at baseline.

RESULTS

During a follow-up time of 6.5 years, participants consuming moderate levels of alcohol had the lowest incidence of mobility limitation (total: 6.4 per 100 person-years (person-years); men: 6.4 per 100 person-years; women: 7.3 per 100 person-years) and mobility disability (total: 2.7 per 100 person-years; men: 2.5 per 100 person-years; women: 2.9 per 100 person-years). Adjusting for demographic characteristics, moderate alcohol intake was associated with lower risk of mobility limitation (hazard ratio (HR)=0.70, 95% confidence interval (CI)=0.55-0.89) and mobility disability (HR=0.66, 95% CI=0.45-0.95) than never or occasional consumption. Additional adjustment for lifestyle-related variables substantially reduced the strength of the associations (HR=0.85, 95% CI=0.66-1.08 and HR=0.81, 95% CI=0.56-1.18, respectively). Adjustment for diseases and health status indicators did not affect the strength of the associations, suggesting that lifestyle is most important in confounding this relationship.

CONCLUSION

Lifestyle-related characteristics mainly accounted for the association between moderate alcohol intake and lower risk of functional decline over time. These findings do not support a direct causal effect of alcohol intake on physical function.

Alcoholic liver disease in the elderly

Although per capita alcohol consumption, and thus the prevalence of alcoholic liver disease, decreases generally with age in Europe and in the United States, recently an increase in alcohol consumption has been reported in individuals over 65 years. Reasons explaining this observation may include an increase in life expectancy or a loss of life partners and, thus, loneliness and depression. Although ethanol metabolism and ethanol distribution change with age, and an elderly person's liver is more susceptible to the toxic effect of ethanol, the spectrum of alcoholic liver diseases and their symptoms and signs is similar to that seen in patients of all ages. However, prognosis of alcoholic liver disease in the elderly is poor. In addition, chronic alcohol consumption may enhance drug associated liver disease and may also act as a cofactor in other liver diseases, such as viral hepatitis and nonalcoholic fatty liver disease.

Alcohol consumption among the elderly in a general population, Erie County, New York

OBJECTIVES

Relatively few studies of drinking among the elderly have been completed despite the growing proportional representation of the elderly in the US population. This study sought to estimate the prevalence of and to observe whether active or health-oriented lifestyles are associated with heavy drinking among the elderly.

METHODS

Random-digit dialing telephone interviews were conducted with 2325 Erie County, New York, general population residents aged 60 years or older.

RESULTS

The prevalence of heavy drinking was 6%. Adjusted analyses showed positive associations between heavy drinking and being male, having suburban residency, and currently using cigarettes. Negative relationships were observed between heavy drinking and socioeconomic status, rural residency, and degree of health orientation. Age and level of active lifestyle were not significant contributors to the model.

CONCLUSIONS

Of the studied variables, health orientation offers the greatest opportunity to address heavy drinking among the elderly.

Addictive behavior of older adults

Very little is known about addictive alcohol use by older people. In the present paper personal effects reasons for drinking (i.e. drinking for the effects of alcohol) and concerns about drinking were used as indicators of addictive drinking behavior among a sample of 826 people aged 65 and older who participated in survey interviews in their homes. The relationship of addictive drinking behavior to frequency of drinking, quantity of drinks per occasion, and depressant drug use was examined. Alcohol use was higher among males and young-old (aged 65-74), while depressant medication use was higher among females and old-old (aged 75+). However, with the exception of use of over-the-counter medications containing codeine (which was significantly higher among current drinkers), no relationship existed between alcohol use and use of depressant medications. Personal effects reasons for drinking and concerns about drinking were related both to alcohol and depressant medication use. Frequency of drinking was associated with higher endorsement of both personal effects and social reasons, whereas volume of alcohol consumption (drinks per drinking day) was associated only with personal effects drinking. In addition, use of depressant medications by drinkers was significantly related to consuming alcohol for personal effects reasons (but unrelated to consuming for social reasons) and with having concerns about one's own drinking. These results suggest that even within the generally low levels of alcohol consumption of older people, addictive-use patterns emerge. In addition, the results confirm the importance of including depressant medication use in evaluating the drinking behavior of older people.

Relationships between macronutrient intake, handicaps, and cognitive impairments in free living elderly people

It is still unknown what if any relationships exist between intake of macronutrients by the elderly, and their functional or cognitive handicaps, particularly for free living elderly people. We investigated 226 men and 215 women, aged 65 or more, free living and in good health. They were randomly selected in the département of Bas-Rhin, after stratification for age, sex and residence (rural or urban). Handicaps and cognitive functions of each subject were assessed with the Géronte scale and the Mini-Mental State Examination (MMSE), respectively. Food intake was measured by a three-day record. A multiple correspondence analysis concluded that functional parameters and macronutrient intakes were rather independent. The relationships found were detailed by a backward stepwise logistic regression. In men, alcohol intake was associated with an improvement in functional and cognitive parameters, and polyunsaturated fatty acids with the capacity to move outside the home. In women, lipid intake increased the MMSE score. Overweight in women was linked with better functional and cognitive performances, and in men with the capacity to move outside the home. In both sexes, age worsened the score of functional and cognitive parameters. In conclusion, macronutrient intakes and functional or cognitive parameters were found to be mutually independent; this suggests that macronutrient deficiencies are of little importance in the worsening functional or mental autonomy of the elderly. The relationships found between functional variables and alcohol or polyunsaturated fatty acid intakes in men, and lipid intakes in women, and overweight in both sexes might evidence a better state of health.

Correlates of impaired function in older women

OBJECTIVE

To determine the factors associated with impaired function in older women.

DESIGN

Cross-sectional analysis of baseline data collected for a multicenter, prospective study of risk factors for osteoporotic fractures.

SETTING

Four clinical centers in Portland, Oregon, Minneapolis, Minnesota, Baltimore, Maryland, and the Monongahela Valley, Pennsylvania.

PARTICIPANTS

A total of 9,704 ambulatory, non-black women, aged 65 years and older, recruited from population-based listings.

MEASUREMENTS

Independent variables, including demographic and historical information (medical conditions, health habits, and medications) and physiologic measures (anthropometry, blood pressure, mental status, vision, and neuromuscular performance) were obtained from a baseline questionnaire, interview, and examination. Measurement of function was assessed by self-reported ability to perform six physical and instrumental activities of daily living (ADL) and impaired function (dependent variable) was defined as difficulty performing three or more physical and instrumental ADLs.

RESULTS

In order of decreasing strength of association, hip fracture, osteoarthritis, parkinsonism, slower walking speed, lower hip abduction force, back pain, greater Quetelet index, osteoporosis, former alcohol use, stroke, never drinking alcohol, lower mental status, use of anxiolytics and/or sleeping medications, inability to hold the tandem position, postural dizziness, cataracts, greater waist to hip ratio, lower physical activity in the past year, greater lifetime cigarette consumption, and lower grip strength were independently associated with impaired function in multivariate analyses. Age, low educational level, diabetes, current heavy alcohol use, postural hypotension, depth perception, and contrast sensitivity were not independent predictors. A combination of neuromuscular performance measures, including decreased muscle strength and impaired balance and gait, appeared to account for the effect of age on disability.

CONCLUSION

A combination of many factors, including medical conditions, health habits such as obesity, smoking, alcohol abstinence, and physical inactivity, and direct measures of neuromuscular performance are associated with impaired function in older women.

Alcohol use and abuse in the frail, homebound elderly: a clinical analysis of 103 persons

We studied alcohol use and abuse in 103 frail, homebound elderly individuals cared for in a long-term home health care program from July 1991 to February 1992. Their average age was 80.63 years. Eighty-four percent were abstinent at the time of the study, including 25 (25%) past heavy drinkers. Two persons were current heavy drinkers and 14 continued to drink socially. Previous alcohol use or abuse was associated with a history of smoking, cardiovascular morbidity, social isolation, and anxiety or agitation. Current social drinking was associated with sedative-hypnotic use as well as smoking. Twenty-three of 25 past heavy drinkers remained sober on our programs without the use of formal alcohol treatment. Abstinence is known to increase with age, appears to be fostered by the homebound setting, is feasible for homebound elderly persons and is often accepted.
