The impact of alcohol use in community-dwelling older adults.

The purpose of this study was to explore the use of alcohol in community-dwelling older adults and to consider differences in physical and mental health, function, cognitive status, and social supports between those who drink minimal (1 to 3 glasses weekly), moderate (4 to 7 glasses weekly), or no alcohol. A total of 3305 older adults with a mean age of 81.6 -/+ 6.0 participated in the study. Twenty-two percent (n = 709) of the participants had 1 to 3 drinks weekly, only 1% (n = 18) reported 4 to 7 drinks weekly, and none of the participants admitted to 8 or more drinks. There was no difference in drinking behavior with regard to age (F = 1.1, p >.05) or social supports (F =.39, p >.05). There was a difference in drinking behavior with regard to physical health (F = 4.9, p <.05), functional status (F = 7.7, p <.05), cognitive status (F = 11.8, p <.05), and mental health (F = 6.9, p <.05). Health care providers should use an individualized approach to alcohol use in older adults and help these individuals establish, as appropriate, safe drinking habits that will augment health and quality of life.

Effects of aerobic exercise training in community-based subjects aged 80 and older: a pilot study.

OBJECTIVES: To assess the ability of sedentary, frail subjects aged 80 and older to train in a community-based exercise program and to evaluate clinical factors that predict improvements in peak oxygen consumption (VO2peak). DESIGN: Pretest, posttest. SETTING: Charlestown Retirement Community, Catonsville, Maryland PARTICIPANTS: Twenty-two (11 male, 11 female; mean age +/- standard deviation = 84 +/- 4.0, range 80-92) self-referred. INTERVENTION: Six months of moderate-intensity aerobic exercise training, two to three sessions/week, 20 to 30 minutes per session. Training modes included treadmill walking and/or stationary cycling. MEASUREMENTS: Baseline and follow-up maximal exercise treadmill tests (ETTs) with electrocardiogram monitoring and respiratory gas analysis. RESULTS: Six months of aerobic exercise training resulted in significant increases (mean +/- standard deviation) in ETT duration (11.9 +/- 3.3 vs 15.9 +/- 4.3 minutes; P =.01), VO2peak (1.23 +/- 0.37 vs 1.31 +/- 0.36 L/min; P =.04), and oxygen pulse (9.3 +/- 2.8 vs 10.1 +/- 3.2; P =.03). Mean heart rate was significantly lower during submaximal ETT stages 1 through 4 (P <.05), and resting systolic blood pressure decreased (146 +/- 18 vs 133 +/- 14 mmHg; P =.01) after training. Multiple regression analysis indicated that baseline VO2peak (r = 0.75, P =.002) and the total amount of time spent in exercise training (r = 0.55, P =.008) were independent predictors of the training-related improvements in VO2peak. CONCLUSION: Subjects aged 80 and older can increase aerobic capacity and reduce systolic blood pressure in a community-based exercise program of moderate intensity. The most important predictors of change in VO2peak were baseline VO2peak and the time spent in exercise training. Subjects with a lower baseline VO2peak had the greatest improvements in VO2peak after training.
