26 January 2022 In Dementia

OBJECTIVE: To examine the moderating effect of older adults' history of drinking problems on the relationship between their baseline alcohol consumption and risk of dementia and cognitive impairment, no dementia (CIND) 18 years later.

METHOD: A longitudinal Health and Retirement Study cohort (n = 4421) was analyzed to demonstrate how older adults' baseline membership in one of six drinking categories (non-drinker, within-guideline drinker, and outside-guideline drinker groups, divided to reflect absence or presence of a history of drinking problems) predicts dementia and CIND 18 years later.

RESULTS: Among participants with no history of drinking problems, 13% of non-drinkers, 5% of within-guideline drinkers, and 9% of outside-guideline drinkers were classified as having dementia 18-years later. Among those with a history of drinking problems, 14% of non-drinkers, 9% of within-guideline drinkers, and 7% of outside-guideline drinkers were classified with dementia. With Non-Drinker, No HDP as reference category, being a baseline within-guideline drinker with no history of drinking problems reduced the likelihood of dementia 18 years later by 45%, independent of baseline demographic and health characteristics; being a baseline within-guideline drinker with a history of drinking problems reduced the likelihood by only 13% (n.s.). Similar patterns obtained for the prediction of CIND.

CONCLUSIONS: For older adults, consuming alcohol at levels within validated guidelines for low-risk drinking may offer moderate long-term protection from dementia and CIND, but this effect is diminished by having a history of drinking problems. Efforts to predict and prevent dementia and CIND should focus on older adults' history of drinking problems in addition to how much alcohol they consume.

17 November 2021 In Cardiovascular System

BACKGROUND: We investigated the association of alcohol consumption with cardiovascular and non-cardiovascular mortality in elderly Chinese men.

METHODS: Our participants were recruited from residents living in a suburban town of Shanghai (>/=60 years of age, n = 1702). Alcohol intake was classified as non-drinkers, past drinkers (stopped drinking for >/=12 months), and current light-to-moderate (1 to 299 g/week) and heavy drinkers (>/=300 g/week). Alcoholic beverages were classified as beer/wine, rice aperitif and liquor/mix drinking.

RESULTS: During 5.9 years (median) of follow-up, all-cause, cardiovascular and non-cardiovascular deaths occurred in 211, 98 and 113 participants, respectively. The corresponding incidence rates were 23.6/1000, 10.9/1000 and 12.6/1000 person-years, respectively. Both before and after adjustment for confounding factors, compared with non-drinkers (n = 843), past drinkers (n = 241), but not the current light-to-moderate (n = 241) or heavy drinkers (n = 377), had a higher risk of all-cause (adjusted hazard ratio [HR] 1.90, 95% confidence interval [CI] 1.35-2.68, P = 0.0003) and non-cardiovascular mortality (HR 2.46, 95% CI 1.55-3.91, P = 0.0001). Similar trends were observed for cardiovascular mortality (HR 1.44, 95% CI 0.85-2.44, P = 0.18). In similar unadjusted and adjusted analyses, compared with the current beer/wine drinkers (n = 203), liquor/mix drinkers (n = 142), but not aperitif drinkers (n = 273), had a significantly higher risk of all-cause (HR 3.07, 95% CI 1.39-6.79, P = 0.006), and cardiovascular mortality (HR 10.49, 95% CI 2.00-55.22, P = 0.006). Similar trends were observed for non-cardiovascular mortality (HR 1.94, 95% CI 0.73-5.16, P = 0.18).

CONCLUSIONS: Our study showed risks of mortality associated with past drinking and liquor drinking in the elderly Chinese men.

22 October 2021 In Drinking Patterns

The aim of this study was to evaluate the longitudinal changes in alcohol consumption (total alcohol and types of alcoholic beverages) of the Greek EPIC cohort participants (28,572) during a 17-year period (1994-2011), with alcohol information being recorded repeatedly over time. Descriptive statistics were used to show crude trends in drinking behavior. Mixed-effects models were used to study the consumption of total alcohol, wine, beer and spirits/other alcoholic beverages in relation to birth cohort, socio-demographic, lifestyle and health factors. We observed a decreasing trend of alcohol intake as age increased, consistent for total alcohol consumption and the three types of beverages. Older birth cohorts had lower initial total alcohol consumption (8 vs. 10 g/day) and steeper decline in wine, spirits/other alcoholic beverages and total alcohol consumption compared to younger cohorts. Higher education and smoking at baseline had a positive association with longitudinal total alcohol consumption, up to +30% (vs. low education) and more than +25% (vs. non-smoking) respectively, whereas female gender, obesity, history of heart attack, diabetes, peptic ulcer and high blood pressure at baseline had a negative association of -85%, -25%, -16%, -37%, -22% and -24% respectively. Alcohol consumption changed over age with different trends among the studied subgroups and types of alcohol, suggesting targeted monitoring of alcohol consumption.

22 October 2021 In Diabetes

OBJECTIVE: To assess the prevalence of metabolic syndrome (MetS) in Chinese adults living in Ningbo and to examine the association between alcohol consumption and MetS and its medical components.

DESIGN: A representative survey in Ningbo was conducted in 2015 covering socio-demography. A FFQ together with additional questionnaires was used to collect information on alcohol consumption, diet, demography, lifestyle and medical information. Multivariable logistic regression and generalised linear models were used to examine the association between alcohol consumption and both MetS and its medical components, respectively.

SETTING: Ningbo, China.

PARTICIPANTS: A total of 2853 adults >/= 20 years (44 % men) in this final analysis.

RESULTS: The prevalence of frequent alcohol drinkers and MetS was 29.9 % and 28.0 %, respectively. Significantly higher prevalence of MetS and mean values of medical components were found in the group of frequent alcohol drinkers with an exception for HDL-cholesterol, compared with less or non-alcohol drinkers. Frequent alcohol consumption was associated with higher odds of developing MetS and positively associated with medical components excepting waist circumference.

CONCLUSIONS: Frequent alcohol consumption contributed to a higher prevalence of MetS and unfavourable influence on MetS and its medical components among Chinese adults. A public health intervention on alcohol restriction is necessary for the prevention and control of the ongoing epidemic MetS.
