The relationship between alcohol consumption and cardiovascular disease risk is complex. Low-to-moderate daily alcohol consumption (1-2 drinks/day) is associated with reduced risk, whereas greater amounts of alcohol consumption and a "binge" pattern of drinking are associated with increased cardiovascular risk and mortality. Arterial stiffness may help explain the complex relationship.

This integrated review summarizes data from studies examining the associations between alcohol consumption and pulse wave velocity, a gold standard measure of arterial stiffness. We also briefly review the concept and methodology of pulse wave velocity measurement as well as the mechanisms of alcohol-induced arterial stiffening.

Findings among the different studies reviewed were inconsistent with methodological challenges related to alcohol use assessment. While making specific conclusions regarding this relationship is tenuous; the data suggest that excessive alcohol consumption or a binge drinking pattern is associated with increased arterial stiffness.

BACKGROUND: In the context of increasing global aging, the long-term effects of alcohol consumption on cognitive function in older adults were analyzed in order to provide rationalized health recommendations to the elderly population.

METHODS: The study used the Chinese Longitudinal Healthy Longevity Survey (CLHLS) dataset, from which 5354 Chinese seniors aged 65-112 years were selected as the subjects, spanning the years 1998-2018. Data on alcohol, diet, activity, and cognition were collected by questionnaire and cognitive levels were judged by the Mini-Mental State Examination scale (also referenced to the Functional Assessment Staging Test). Data cleaning and preprocessing was implemented by R software. The dynamic Cox model was applied for model construction and data analysis.

RESULTS: The results of the dynamic Cox model suggested that seniors who drank alcohol were at higher risk of cognitive decline compared to those who never drank (HR = 1.291, 95%CI: 1.175-1.419). The risk was similarly exacerbated by perennial drinking habits (i.e., longer drinking years, HR = 1.008, 95%CI: 1.004-1.013). Compared to non-alcoholic beverages, liquor (>/= 38 degrees ), liquor (< 38 degrees ), wine and rice wine all showed negative effects. Whereas, the risk of cognitive decline was relatively lower in seniors who consumed liquors (< 38 degrees ) and rice wine compared to the high-level liquor (HR: 0.672 (0.508, 0.887) and 0.732 (0.559, 0.957), respectively).

CONCLUSIONS: Alcohol consumption has a negative and long-term effects on cognitive function in seniors. For the elderly, we suggested that alcohol intake should be avoided as much as possible.

BACKGROUND: The existing findings of the longitudinal impact of low-to-moderate drinking on symptomatic depression were controversial, as results ranged from finding no association to finding both a protective and adverse association. METHODS: The present study examined the association between low-to-moderate alcohol consumption and incident depressive symptoms by pooled analysis of three European, American and Chinese representative samples of middle-aged and older adults. RESULTS: A total of 29,506 participants (55.5% female) were included. During 278,782 person-years of follow-up, we found that subjects with low-to-moderate drinking had a significantly lower incidence of depressive symptoms compared to never-drinking subjects, with pooled hazard ratios of 0.87 (95% confidence interval [CI]: 0.79-0.96) for men and 0.87 (95% CI: 0.80-0.95) for women, whereas heavy drinkers failed to show significantly higher risk of depressive symptoms. Furthermore, a J-shaped relation between alcohol consumption and incident depressive symptoms was identified in Chinese men, US men, and UK men and women. LIMITATIONS: The classification of depressive symptoms based on the Center for Epidemiologic Studies Depression Scale may not be completely comparable to diagnosis from a clinical setting. CONCLUSIONS: Low-to-moderate alcohol consumption was significantly associated with a lower risk of depressive symptoms on a long-term basis compared to never drinking. Our results support the threshold of moderate drinking in current US guidelines. However, caution should be exercised in engaging in guideline-concordant drinking habits, for even moderate drinkers are at risk of developing heavy drinking habits and experiencing future alcohol-related problems.
