BACKGROUND: Alcohol intake is widely assumed to contribute to excess body fatness, especially among young men; however, the evidence is inconsistent. We have addressed this research question by investigating associations between reported alcohol consumption and body composition from large representative national surveys in a high alcohol-consuming country with a high obesity prevalence.

METHODS: The present study comprised a secondary analysis of combined cross-sectional nationally representative Scottish Health Surveys (1995-2010). Reported alcohol-drinking frequency was divided into five groups: from 'nonfrequent drinking' (reference) to daily/'almost every day' among 35 837 representative adults [mean (SD) age: 42.7 (12.7) years (range 18-64 years)]. Quantitative alcohol consumption was categorised into seven groups: from '1-7 to >/=50 10 g units per week'. Regression models against measured body mass index (BMI) and waist circumference (WC) were adjusted for age, physical activity, income, smoking, deprivation category and economic status.

RESULTS: Among alcohol-consuming men, heavier drinking (21-28 units per week) was associated with a higher BMI by +1.4 kg m(-2) [95% confidence interval (CI) = 1.38-1.43] and higher WC by +3.4 cm (95% CI = 3.2-3.6) than drinking 1-7 units per week. However, those who reported daily drinking frequency were associated with a lower BMI by -2.45 kg m(-2) (95% CI = -2.4 to -2.5) and lower WC by -3.7 cm (95% CI = -3.3 to -4.0) than those who reported less-frequent drinking. Similar associations were found for women. Most of these associations were restricted to subjects aged >30 years. Unexplained variances in BMI and WC are large.

CONCLUSIONS: Quantitative alcohol consumption and frequency of consumption were positively and inversely associated, respectively, with both BMI and WC among alcohol-consuming adults. Surveys are needed that evaluate both the quantity and frequency of consumption. The lowest BMI and WC were associated with a 'Mediterranean' drinking style (i.e. relatively little, but more frequently).

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.

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.
