Alcohol consumption and cardiovascular mortality among U.S. adults, 1987 to 2002

Metabolic dysfunction-associated fatty liver disease and heavy alcohol consumption increase mortality:A nationwide study

BACKGROUND

The effects of excessive alcohol consumption on the prognosis of metabolic dysfunction-associated fatty liver disease (MAFLD) remain unclear. We investigated all-cause and cause-specific mortality according to the amount of alcohol consumed by Asian individuals with MAFLD.

METHODS

This nationwide retrospective study included 996,508 adults aged 40-79 years who underwent health check-ups between 2009 and 2012. Participants were categorized by the alcohol consumption-non-alcohol, moderate alcohol, and heavy alcohol group (≥ 30 g/day for men, ≥ 20 g/day for women) and by the combination of the presence or absence of MAFLD. Hepatic steatosis was defined as the fatty liver index ≥ 30. Cox analyses were used to analyze the association between alcohol consumption and MAFLD and all-cause and cause-specific mortality.

RESULTS

MAFLD significantly increased all-cause, liver-, and cancer-related mortality. Individuals with both MAFLD and heavy alcohol consumption expressed the highest mortality risk in liver-related mortality compared to non-MAFLD and non-alcohol group (adjusted hazard ratio (HR), 9.8; 95% confidence interval (CI), 8.20-12.29). Regardless of MAFLD, heavy alcohol consumption increased the risk of liver- and cancer-related mortality.

CONCLUSIONS

MAFLD and heavy alcohol consumption increased all-cause, liver-, and cancer-related mortality. Heavy alcohol consumption and MAFLD synergistically increase liver-related mortality.

Disparities in Smoking and Heavy Drinking Behaviors by Disability Status and Age of Disability Onset: Secondary Analysis of National Health Interview Survey Data

OBJECTIVES

People with childhood-onset disabilities are living into adulthood, and the prevalence of smoking and illicit drug use among adults with disabilities is high. We evaluated the relationship between disability status and age of disability onset, current cigarette smoking status, and heavy alcohol drinking.

METHODS

We conducted a secondary data analysis of the National Health Interview Survey (NHIS), a US survey on illness and disability. Among 2020 NHIS participants aged 22-80 years (n = 28 225), we compared self-reported prevalence of current cigarette smoking and heavy alcohol drinking among those with and without disabilities and among those with childhood- versus adult-onset disabilities. We used adjusted logistic regression analysis to calculate the adjusted odds ratios (AORs) of current smoking and heavy alcohol drinking based on disability status and age of disability onset.

RESULTS

Compared with adults without disabilities, adults with disabilities were significantly more likely to report current smoking (23.5% vs 11.2%; P < .001) and significantly less likely to report heavy alcohol drinking (5.3% vs 7.4%; P = .001). The prevalence of these behaviors did not vary significantly by age of disability onset. In adjusted logistic regression models, adults with disabilities had significantly higher odds of current smoking (AOR = 1.76; 95% CI, 1.53-2.03) and similar odds of heavy alcohol drinking (AOR = 0.82; 95% CI, 0.65-1.04) compared with adults without disabilities. The odds of these health behaviors did not vary significantly by age of disability onset.

CONCLUSIONS

Adults with disabilities overall may be at high risk for these unhealthy behaviors, particularly smoking, regardless of age of disability onset. Routine screening and cessation counseling related to smoking and unhealthy alcohol use are important for all people with disabilities.

Poor Physical Health in Caregivers of Children with ADHD or ASD and its Association with Health Risk Behaviours: NHIS 2016-2018

BACKGROUND

There is a dearth of evidence regarding physical health problems and health risk behaviours (e.g., drinking, physical inactivity, smoking, and suboptimal sleep behaviour) in caregivers of children with attention deficit hyperactivity disorder or autism spectrum disorder (CCAA). The purposes of the current study were to examine differences in physical health problems between CCAA and caregivers of children without attention deficit hyperactivity disorder and autism spectrum disorder (CCWAA) and to explore health risk behaviours associated with those problems.

METHOD

Data from the 2016-2018 National Health Interview Survey were used in the current study. 10 common physical health problems were compared between CCAA and CCWAA by using multivariable logistic regressions. In addition, in order to detect associated health risk behaviours, decision tree analysis was performed for physical health problems in CCAA.

RESULTS

Of the 10 physical health problems, caregivers of children with ADHD showed significantly higher likelihood of experiencing nine (arthritis, asthma, back pain, high cholesterol, diabetes, heart problems, hypertension, neck pain, obesity), compared to CCWAA. Caregivers of children with autism spectrum disorder (ASD) showed significantly higher likelihoods of experiencing two physical health problems compared to CCWAA. The decision tree analysis revealed that age (> 42 years), and suboptimal sleep behaviour (not 7-8 hours), and smoking (current smoker) were the frequent predictors for physical health problems in CCAA.

CONCLUSION

The results of the current study represent an important milestone in further investigating physical health problems in CCAA.

Resistant hypertension: consensus document from the Korean society of hypertension

Although reports vary, the prevalence of true resistant hypertension and apparent treatment-resistant hypertension (aTRH) has been reported to be 10.3% and 14.7%, respectively. As there is a rapid increase in the prevalence of obesity, chronic kidney disease, and diabetes mellitus, factors that are associated with resistant hypertension, the prevalence of resistant hypertension is expected to rise as well. Frequently, patients with aTRH have pseudoresistant hypertension [aTRH due to white-coat uncontrolled hypertension (WUCH), drug underdosing, poor adherence, and inaccurate office blood pressure (BP) measurements]. As the prevalence of WUCH is high among patients with aTRH, the use of out-of-office BP measurements, both ambulatory blood pressure monitoring (ABPM) and home blood pressure monitoring (HBPM), is essential to exclude WUCH. Non-adherence is especially problematic, and methods to assess adherence remain limited and often not clinically feasible. Therefore, the use of HBPM and higher utilization of single-pill fixed-dose combination treatments should be emphasized to improve drug adherence. In addition, primary aldosteronism and symptomatic obstructive sleep apnea are quite common in patients with hypertension and more so in patients with resistant hypertension. Screening for these diseases is essential, as the treatment of these secondary causes may help control BP in patients who are otherwise difficult to treat. Finally, a proper drug regimen combined with lifestyle modifications is essential to control BP in these patients.

Alcohol consumption and all-cause and cause-specific mortality among US adults: prospective cohort study

BACKGROUND

Previous studies have shown inconsistent findings regarding the association of light to moderate alcohol consumption with cause-specific mortality. Therefore, this study sought to examine the prospective association of alcohol consumption with all-cause and cause-specific mortality in the US population.

METHODS

This was a population-based cohort study of adults aged 18 years or older in the National Health Interview Survey (1997 to 2014) with linkage to the National Death Index records through December 31, 2019. Self-reported alcohol consumption was categorized into seven groups (lifetime abstainers; former infrequent or regular drinkers; and current infrequent, light, moderate, or heavy drinkers). The main outcome was all-cause and cause-specific mortality.

RESULTS

During an average follow-up of 12.65 years, among the 918,529 participants (mean age 46.1 years; 48.0% male), 141,512 adults died from all causes, 43,979 from cardiovascular disease (CVD), 33,222 from cancer, 8246 from chronic lower respiratory tract diseases, 5572 from accidents (unintentional injuries), 4776 from Alzheimer's disease, 4845 from diabetes mellitus, 2815 from influenza and pneumonia, and 2692 from nephritis, nephrotic syndrome, or nephrosis. Compared with lifetime abstainers, current infrequent, light, or moderate drinkers were at a lower risk of mortality from all causes [infrequent-hazard ratio: 0.87; 95% confidence interval: 0.84 to 0.90; light: 0.77; 0.75 to 0.79; moderate 0.82; 0.80 to 0.85], CVD, chronic lower respiratory tract diseases, Alzheimer's disease, and influenza and pneumonia. Also, light or moderate drinkers were associated with lower risk of mortality from diabetes mellitus and nephritis, nephrotic syndrome, or nephrosis. In contrast, heavy drinkers had a significantly higher risk of mortality from all causes, cancer, and accidents (unintentional injuries). Furthermore, binge drinking ≥ 1 day/week was associated with a higher risk of mortality from all causes (1.15; 1.09 to 1.22), cancer (1.22; 1.10 to 1.35), and accidents (unintentional injuries) (1.39; 1.11 to 1.74).

CONCLUSIONS

Infrequent, light, and moderate alcohol consumption were inversely associated with mortality from all causes, CVD, chronic lower respiratory tract diseases, Alzheimer's disease, and influenza and pneumonia. Light or moderate alcohol consumption might also have a beneficial effect on mortality from diabetes mellitus and nephritis, nephrotic syndrome, or nephrosis. However, heavy or binge had a higher risk of all-cause, cancer, and accidents (unintentional injuries) mortality.

Alcohol and the vasculature: a love-hate relationship?

Alcohol consumption is a leading risk factor and increases the risk of liver diseases, cancers, tuberculosis, and injuries. The relationship between alcohol use and cardiovascular risk is complex. While it is well established that heavy alcohol use and binge drinking harm cardiovascular health, the effect of light-to-moderate alcohol consumption remains controversial. Observational studies have repeatedly confirmed the U- or J-shaped relationship between alcohol consumption and cardiovascular disease risk, with the lowest risk observed in the light-to-moderate drinking group. However, the protective effect of low-level alcohol has been challenged by recent genetic epidemiological studies with Mendelian randomization. Such studies have their own limitations, and the application of this methodology in studying alcohol has been questioned. Results from the latest Global Burden of Diseases, Injuries, and Risk Factors Study suggest that the impact of alcohol consumption on health depends on the age structure and the distribution of disease burden and underlying causes in a given population. For young adults, even small amounts of alcohol cause heath loss. For older adults facing a high burden of cardiovascular diseases, light-to-moderate alcohol consumption may improve cardiovascular health outcomes. Mechanistically, all types of alcoholic beverages, including wine, spirits, and beer, have been shown to increase the levels of high-density lipoprotein cholesterol and adiponectin, and reduce the level of fibrinogen. Nonalcoholic components of wine, especially polyphenolic compounds like resveratrol, may additionally enhance endothelial nitric oxide production, and provide antioxidant and anti-inflammatory effects.

Depressive symptoms and risk of incident cardiometabolic multimorbidity in community-dwelling older adults: The China Health and Retirement Longitudinal Study

BACKGROUND

Depressive symptoms are associated with an increased risk of developing cardiometabolic diseases (CMDs). However, the relationship between depressive symptoms and cardiometabolic multimorbidity (CMM) remains unclear. Therefore, we aimed to examine whether depressive symptoms were associated with an increased risk of incident CMM in middle-aged and older Chinese adults.

METHODS

This prospective cohort study included 6663 participants who were free of CMM at baseline from the China Health and Retirement Longitudinal Study. Depressive symptoms were assessed by the Center for Epidemiologic Studies Depression Scale-10 (CESD-10). Incident CMM refers to the coexistence of ≥2 CMDs (heart disease, stroke, or diabetes). Multivariable logistic regressions and restricted cubic splines were performed to assess the association between depressive symptoms and incident CMM.

RESULTS

The median CESD-10 score at baseline was 7 (IQR: 3 to 12). Over 4 years of follow-up, 309 participants (4.6 %) developed CMM. After adjusting for sociodemographic, behavioral, and traditional clinical risk factors, a higher frequency of depressive symptoms was associated with an increased risk of incident CMM (per 9-point higher CESD-10 score OR: 1.73; 95 % CI: 1.48-2.03). The association between the CESD-10 score and incident CMM was more obvious in women (OR: 2.02; 95 % CI: 1.63-2.51) than in men (OR: 1.16; 95 % CI: 0.86-1.56) (P_interaction = 0.005).

LIMITATIONS

Heart diseases and stroke were determined based on self-reported physician diagnoses.

CONCLUSIONS

A higher frequency of depressive symptoms at baseline increased the risk of incident CMM within four years among middle-aged and older individuals in China.

Evaluation of cardiovascular risk biomarkers after moderate consumption of red wine and cachaça in a randomized crossover trial: The Wine and Cachaça Study (WICAS)

INTRODUCTION

Moderate daily consumption of alcohol (MDCA) is associated with cardiovascular risk (CVR) reduction in observational studies. Some researches have suggested that this benefit may be associated not only with red wine consumption but also with other beverages. However, there are no clinical trials evaluating the possible CVR benefit of Brazilian spirit (cachaça) in humans.

METHODS

This is a prospective, randomized, crossover study including healthy individuals initially assigned to a MDCA of cachaça or red wine for a period of 4 weeks. After a one-week abstinence period, the type of drink was changed for another 4 weeks of intervention. The MDCA for both beverages was determined as a dose equivalent to 28 g of ethanol per day for men and 14 g for women. CVR biomarkers analyses were performed before and after each intervention to assess the serologic status of C-reactive protein, lipid profile, platelet aggregation and glycemic profile. This study is registered on the ISRCTN platform under number 15978506.

RESULTS

Of the 42 subjects initially randomized, 2 refused to continue in the study. The median age was 44.3 ± 10.3 years and 19 were male (47.5%). Adherence to the protocol was considered ideal with 100% regular use in both interventions and only 3 individuals in each intervention group reported alcohol abuse. There was no significant variation in anthropometric measurements during the study, except for weight gain (0.7 kg) in the red wine group (p = 0.005). The median of the delta of platelet aggregation for MDCA of cachaça was 1.2% (-1.1 to 5.3) and the median of the delta to the MDCA of wine was -1.6% (-4.5 to 2) (p = 0.02). The other biomarkers didn't show any statistically significant variation.

CONCLUSION

Moderate consumption of wine and cachaça was related to variation in laboratory biomarkers of CVR related to atherosclerosis. There was significant weight gain during the period of wine consumption and there was observed a difference between platelet aggregation values after both interventions.

Alcohol Consumption and Cardiovascular Health

BACKGROUND

Studies evaluating alcohol consumption and cardiovascular diseases have shown inconsistent results.

METHODS

We performed a systematic review of peer-reviewed publications from an extensive query of Ovid MEDLINE, Ovid Embase, Ovid Cochrane Database of Systematic Reviews, Scopus, and Web of Science from database inception to March 2022 for all studies that reported the association between alcohol consumption in terms of quantity (daily or weekly amounts) and type of beverage (wine, beer or spirit) and cardiovascular disease events.

RESULTS

The study population included a total of 1,579,435 individuals based on 56 cohorts from several countries. We found that moderate wine consumption defined as 1-4 drinks per week was associated with a reduction in risk for cardiovascular mortality when compared with beer or spirits. However, higher risk for cardiovascular disease mortality was typically seen with heavier daily or weekly alcohol consumption across all types of beverages.

CONCLUSIONS

It is possible that the observational studies may overestimate the benefits of alcohol for cardiovascular disease outcomes. Although moderate wine consumption is probably associated with low cardiovascular disease events, there are many confounding factors, in particular, lifestyle, genetic, and socioeconomic associations with wine drinking, which likely explain much of the association with wine and reduced cardiovascular disease events. Further prospective study of alcohol and all-cause mortality, including cancer, is needed.

Alcohol and Cardiovascular Diseases—Do the Consumption Pattern and Dose Make the Difference?

Excessive consumption of alcohol is not only a social problem, but it also significantly increases the morbidity and mortality rates of many societies. A correlation has been demonstrated between alcohol consumption and increased mortality from cancer, accidents and injuries, liver cirrhosis and other causes. Alcohol abuse increases the incidence of hemorrhagic stroke and the risk of ischemic stroke, induces serious arrhythmias, adversely affects blood pressure and damages the heart muscle. The dose and way of drinking alcohol play a crucial role in assessing whether this drink allows people to maintain health or whether it is a great health and social threat. The beneficial effects of low and moderate doses of alcohol on the occurrence of cardiovascular diseases have been shown in many population studies and meta-analyses in which the effect of U-shaped or J-shaped curves relating alcohol intake to cardiovascular mortality was observed, especially in ischemic heart disease. However, due to the fact that alcohol consumption is associated with many health hazards, it is not recommended to consume it as a preventive action of cardiovascular diseases. Moreover, recent studies suggest that association of low-to-moderate alcohol consumption with the reduction in cardiovascular risk is a result of lifestyle changes and that any reduction in alcohol consumption is in fact beneficial in terms of general health.

Relation of Patient's Opinion of Alcohol's Health Effects and Drinking Habits Among Hospitalized Patients With Cardiovascular Disease

Media reports frequently cite observational studies and meta-analyses to promote the reputed cardiovascular benefits of moderate alcohol consumption; however, it is unclear whether public opinion or drinking behavior align with these reports. We administered an anonymous, single-center, 35-question, cross-sectional survey among patients hospitalized for acute cardiac illnesses from June to September 2019, who were eligible for cardiac rehabilitation. We assessed patient opinions toward alcohol use, perceptions of alcohol's health impact, and role of media in forming these beliefs. We hypothesized that drinking habits are associated with beliefs about the health benefits of alcohol consumption. Of 300 patients approached, 290 completed the survey (97%). Most (69%) reported having heard moderate alcohol use is heart healthy from 1 or more sources including: TV (61%), family/friends (33%), newspapers (21%), and the internet (10%); although, only 19% reported believing these reports. In total, 12 patients (4%) reported intentionally increasing alcohol intake because of the reported beneficial health effects. There was a strong association between binge drinking and increasing alcohol used to improve cardiac health (odds ratio 8.8, 95% confidence interval 2.7, 29). Given the known cardiotoxic effects of alcohol, particularly in large doses, strategies aimed at population-based education regarding the unhealthy cardiovascular impact of alcohol use is needed, especially among binge drinkers.

Modifiable Lifestyle Behaviors and CKD Progression: A Narrative Review

Living a healthy lifestyle is one of the safest and most cost-effective ways to improve one's quality of life and prevent and/or manage chronic disease. As such, current CKD management guidelines recommend that patients adhere to a healthy diet, perform ≥150 minutes per week of physical activity, manage their body weight, abstain from tobacco use, and limit alcohol. However, there are limited studies that investigate the relationship between these lifestyle factors and the progression of CKD among people with established CKD. In this narrative review, we examine the reported frequencies of health lifestyle behavior engagement among individuals with non-dialysis-dependent CKD and the existing literature that examines the influences of diet, physical activity, weight management, alcohol consumption, and tobacco use on the progression of CKD, as measured by decline in GFR, incident ESKD, or elevated proteinuria or albuminuria in individuals with CKD. Many of the available studies are limited by length of follow-up and small sample sizes, and meta-analyses were limited because the studies were sparse and had heterogeneous classifications of behaviors and/or referent groups and of CKD progression. Further research should be done to determine optimal methods to assess behaviors to better understand the levels at which healthy lifestyle behaviors are needed to slow CKD progression, to investigate the effect of combining multiple lifestyle behaviors on important clinical outcomes in CKD, and to develop effective techniques for behavior change. Despite the lack of evidence of efficacy from large trials on the ability of lifestyle behaviors to slow CKD progression, maintaining a healthy lifestyle remains a cornerstone of CKD management given the undisputed benefits of healthy lifestyle behaviors on cardiovascular health, BP control, and survival.

Alcohol Consumption and Cardiovascular Disease Risk: Placing New Data in Context

Purpose of Review

A clear link between excessive alcohol consumption and cardiovascular disease (CVD) has been established, but no consensus exists on the effects of moderate alcohol consumption on CVD.

Recent Findings

A lower risk of coronary heart disease and myocardial infarction among moderate drinkers compared to abstainers has been consistently observed in epidemiological studies and meta-analyses of these studies. However, ambiguity remains on the effect of alcohol on other CVDs and all-cause mortality. Short-term randomized controlled trials (RCT) have identified potentially beneficial effects of alcohol consumption on cardiovascular risk factors, but studies investigating genetic polymorphisms that influence alcohol consumption (i.e., Mendelian randomization) have yielded inconclusive results. To date, a long-term RCT providing causal evidence is lacking but urgently needed.

Summary

Triangulation of evidence from different study designs, including long-term RCTs, pragmatic trials and the evaluation of policy measures, combined will lead to the best available evidence.

Fit and Tipsy? The Interrelationship between Cardiorespiratory Fitness and Alcohol Consumption and Dependence

PURPOSE

To examine whether higher levels of cardiorespiratory fitness are related to increased alcohol consumption and dependence among a large sample of adults attending a preventive medicine clinic.

METHODS

A cross-sectional study of 38,653 apparently healthy patients who visited the Cooper Clinic (Dallas, TX) for preventive medical examinations (1988-2019) and enrolled in the Cooper Center Longitudinal Study. The primary independent variable was cardiorespiratory fitness, based on a maximal treadmill test, and the dependent variables were alcohol consumption and dependence (self-reported). The relations between fitness category (low, moderate, high) and alcohol consumption (low, moderate, heavy) and suggested alcohol dependence (Cut down, Annoyed, Guilty, Eye opener score ≥2) among women and men were estimated via multivariable regression while adjusting for covariates (e.g., age, birth year cohort, marital status, and body mass index).

RESULTS

Women within the moderate and high fitness categories had 1.58 (95% confidence interval [CI], 1.32-1.91) and 2.14 (95% CI, 1.77-2.58) greater odds of moderate/heavy alcohol consumption, respectively, in comparison to their low fitness counterparts. Similarly, moderate and high fit men had 1.42 (95% CI, 1.30-1.55) and 1.63 (95% CI, 1.49-1.80) times greater odds of moderate-to-heavy alcohol consumption, respectively, in comparison to the low fitness group. In addition, among men who were heavy drinkers (but not women), higher fitness levels were related to lower rates of suggested alcohol dependence. Specifically, these men had 45.7%, 41.7%, and 34.9% proportions of clinically relevant alcohol problems across low, moderate, and high fitness categories (adjusted P for trend <0.001).

CONCLUSIONS

Higher fitness levels are significantly related to greater alcohol consumption among a large cohort of adult patients. Interventions focusing on increasing fitness (via physical activity promotion) might consider concurrently aiming to reduce alcohol consumption.

Stroke and death-findings from a 25-year follow-up of a cohort of employed Swedish middle-aged men of the Coeur study

Aim

In 1993, a study of 1000 automotive workers in Sweden and France looked into national differences of cardiovascular disease. Here, we evaluate the proportion of the Swedish cohort that suffered a stroke or died over a 25-year period and associated risk factors.

Subject and methods

Data from 1993 included a life-style questionnaire, a health examination and laboratory data. Figures on stroke and survival status up until the end of 2018 were collected from national registers. Survival analysis was used for both univariable and multivariable analyses to study associations between potential risk factors and stroke and death, respectively.

Results

By the end of 2018, 65 individuals had suffered a stroke and 160 had died. In the univariable analysis, we found age, systolic blood pressure, Framingham risk index and diabetes at baseline to be significantly associated with stroke during follow-up.

For death, most of the traditional risk factors were significantly associated with the outcome, as was blue-collar work and living alone. In the multivariable analysis, age and diabetes at baseline remained significantly associated with stroke, whereas eight factors (age, blue-collar work, living alone, systolic blood pressure, waist–hip ratio, smoking habits, diabetes and hypertension at baseline) were significantly associated with death during follow-up.

Conclusion

Few of the traditional risk factors were significantly associated with stroke possibly explained by low power and/or different pathogenetic mechanism than for myocardial infarction.

Partly because death occurred more often, we did find a number of potential risk factors to be significantly associated with this outcome.

Alcohol Exerts a Shifted U-Shaped Effect on Central Blood Pressure in Young Adults

BACKGROUND

Consumption of 1-2 alcoholic beverages daily has been associated with a lower risk of cardiovascular disease and all-cause mortality in middle-aged and older adults. Central blood pressure has emerged as a better predictor of cardiovascular risk than peripheral blood pressure. However, the effects of habitual alcohol consumption on central blood pressure particularly in young adults, who are among the largest consumers of alcohol in North America, have yet to be investigated.

OBJECTIVE

We aimed to study the effect of alcohol consumption on central and peripheral blood pressure, and arterial stiffness in young adults.

DESIGN

Cross-sectional observational study.

MAIN MEASURES

Using a standardized questionnaire, alcohol consumption (drinks/week) was queried; participants were classified as non- (< 2), light (2-6), moderate (women 7-9, men 7-14), and heavy drinkers (women > 9, men > 14). Central blood pressure and arterial stiffness were measured using applanation tonometry.

KEY RESULTS

We recruited 153 healthy, non-smoking, non-obese individuals. We found a U-shaped effect of alcohol consumption on blood pressure. Light drinkers had significantly lower central systolic and mean arterial blood pressure, but not peripheral blood pressure when compared to non- and moderate/heavy drinkers (P < 0.05). No significant associations with arterial stiffness parameters were noted.

CONCLUSIONS

A U-shaped relationship was found between alcohol consumption and central and mean arterial blood pressure in young individuals, which importantly, was shifted towards lower levels of alcohol consumption than currently suggested. This is the first study, to our knowledge, that examines the effect of alcohol consumption on central blood pressure and arterial stiffness exclusively in young individuals. Prospective studies are needed to confirm the relationships observed herein.

Frequency of Hazardous and Binge Drinking Alcohol Among Hospitalized Cardiovascular Patients

Excessive alcohol use is a risk factor for most cardiac diseases. The prevalence of unhealthy alcohol use among hospitalized cardiac patients is uncertain as is the frequency with which it is addressed. We performed a single center, patient-level anonymous survey among hospitalized cardiac patients eligible for cardiac rehabilitation. Hazardous drinking was defined as an Alcohol Use Disorders Identification Test (AUDIT) score of 8 or greater. Binge drinking was defined as 5+ drinks for men or 4+ for women on ≥1 occasion within the past 30 days. Unhealthy drinking was defined as either hazardous or binge drinking. Of 300 patients approached, 290 (96.7%) completed the survey. Mean ( ± SD) age was 69 ± 11 years; 70% were male and 31% were cardiac surgical patients. The proportion (95% CI) of hazardous, binge, and unhealthy drinking was 12% (9 to 16), 16% (12 to 20), and 18% (14-23), respectively. Overall, 58% of subjects reported being screened for alcohol use, mostly by nurses (56%). Those with unhealthy drinking reported being counseled more frequently about their alcohol use compared to non-unhealthy drinkers (11% versus 3%, p = 0.03), but the large majority (89%) of unhealthy drinkers reported receiving no advice about their alcohol use while admitted. In conclusion, almost one-fifth of hospitalized cardiac patients reported unhealthy drinking, these patients were only screened about half of the time, and were rarely counseled about their alcohol use.

The positive association between physical activity and alcohol use in African American adults

•

Alcohol intake positively associated with physical activity in African Americans.

•

This association appears to be driven by females, with no association in males.

•

Alcohol intake not associated with Body Mass Index in this African American sample.

African Americans have highest incidence and mortality from obesity-related cancers. Physical activity (PA), minimal alcohol use, and maintaining a low body mass index (BMI) are important cancer prevention behaviors, though there is little research on how these behaviors are associated with one another in African Americans. The purpose of this study is to assess the relationship between PA, alcohol use, and BMI using secondary data from an African American cohort recruited from Houston-area churches. Self-administered questionnaires measured self-reported PA, alcohol use, height, weight, and sociodemographic factors. Univariate and multivariable analyses assessed the relation between PA, alcohol use, BMI, controlling for covariates. Participants (N = 1009) were mostly female (77%), employed (72%), and college graduates (55%). Most (53%) reported both light-to-moderate alcohol use & moderate-to-high levels of PA. There was a statistically significant positive linear association between PA and alcohol use (Pearson’s r = 0.15, p < 0.001). We also found that every one hour increase per week in PA was associated with 3% increased odds of being a heavy drinker (>2 drinks/day men, >1 drink/day women), as compared to an abstainer (Adjusted OR = 1.03, 95%CI 1.01–1.06). There was a statistically significant inverse association between PA and BMI, but no statistically significant association between alcohol use and BMI. In this sample of African Americans, PA and alcohol use were positively associated, mirroring results among Non-Hispanic Whites. However, alcohol use and BMI were not statistically significantly associated. Cancer and obesity prevention for African Americans should stress PA promotion while emphasizing messaging to curtail any associated increases in alcohol use.

A Matched Control Analysis on the Effects of Alcohol Use Disorder After Primary Total Knee Arthroplasty in Medicare Patients

INTRODUCTION

Several studies have found the negative impact of alcohol use disorder (AUD), most notably coagulation derangements. We sought to investigate the effects of AUD after primary total knee arthroplasty (TKA) for (1) postoperative complications, (2) lengths of stay, and (3) costs of care.

METHODS

This was a retrospective database analysis of Medicare patients with AUD undergoing primary TKA performed between 2005 and 2014. Patients with AUD were matched to controls in a 1:5 ratio by age, sex, and medical comorbidities. The query yielded 354,690 TKA patients: 59,126 with AUD and 295,564 without AUD.

RESULTS

Patients with AUD had significantly greater odds ratio (OR) of medical complications, including venous thromboembolism (VTE) within 90 days (OR: 1.41, P < 0.0001) and at 1 year (OR: 1.51, P < 0.0001) and greater 2-year implant-related complications after primary TKA. Furthermore, patients with AUD had significantly longer lengths of stay (4 versus 3 days, P < 0.0001) and incurred a significantly higher episode of care costs ($15,569.76 versus $13,763.06, P < 0.0001).

DISCUSSION

The present study demonstrated a significant association between AUD and the development of VTE. We hope this research will aid in risk stratification and tailoring of VTE chemoprophylaxis and postoperative management in this at-risk group after TKA.

LEVEL OF EVIDENCE

Level III.

Drugs of Abuse and Heart Failure

Substance use is common among those with heart failure (HF) and is associated with worse clinical outcomes. Alcohol, tobacco, cannabis, and cocaine are commonly abused substances that can contribute to the development and worsening of HF. Heavy alcohol consumption can lead to dilated cardiomyopathy, whereas moderate intake may decrease incident HF. Tobacco increases the risk of HF through coronary artery disease and coronary artery disease-independent mechanisms. Continued smoking worsens outcomes for those with HF and cessation is associated with an improved risk of major adverse cardiac events. Cannabis has complex interactions on the cardiovascular system depending on the method of consumption, amount consumed, and content of cannabinoids. Delta-9-tetrahydrocannabinol can increase sympathetic tone, cause vascular dysfunction, and may increase the risk of myocardial infarction. Cannabidiol is cardioprotective in preclinical studies and is a potential therapeutic target. Cocaine increases sympathetic tone and is a potent proarrhythmogenic agent. It increases the risk of myocardial infarction and can also lead to a dilated cardiomyopathy. The use of beta-blockers in those with HF and cocaine use is likely safe and effective. Future studies are needed to further elucidate the impact of these substances both on the development of HF and their effects on those who have HF.

Alcohol, health and cardiovascular disease

Recent epidemiological studies have shown that alcohol consumption can increase the risk of arterial hypertension, atrial fibrillation and gastrointestinal and breast cancer. Various sectors are therefore promoting abstinence from alcohol. However, light alcohol consumption has once again been shown to reduce the risk of myocardial infarction and diabetes but with an unclear effect on cerebrovascular disease. The decision to consume alcohol should therefore be an individual one based on personal factors. A level of consumption <100g/week for men (less for women) appears not to increase all-cause mortality, while high consumption or binge drinking significantly increases mortality risk. All measures to prevent this type of consumption, especially among the younger population, should therefore be applied. There are data indicating an advantage of wine over other beverages, but they are not conclusive.

Prevalence and Factors Associated With Alcohol Use in Selected Urban Communities in Ibadan, Nigeria

Nigeria is ranked high among African countries in the consumption of alcohol and the national adult per capita consumption was estimated at 12.3litres. Harmful alcohol use is the sixth leading cause of disability and deaths in Nigeria. This study assessed the prevalence and factors associated with alcohol use in selected urban communities in Ibadan, Nigeria. This community-based cross sectional study was conducted among 500 respondents in two selected urban communities in Ibadan, Nigeria. The World Health Organization STEPS tool was used to collect data on socio-demographic characteristics of respondents and the history of alcohol use. Alcohol users were categorized into ever consumed, current consumers, consumers within last 12 months, and frequent consumers within 30 days (low, medium, and high consumers).Chi-square analysis was used to identify factors associated with the different categories of alcohol consumption. The mean age of the respondents was 35.36 ± 12.24 years. Almost one third of the participants (29.0%) reported they had ever consumed alcohol and (13.6%) had consumed alcohol within 30 days prior to the study. Factors significantly associated with the ever-use of alcohol were gender (p = 0.000), and income (p = 0.000). Current use of alcohol had a statistically significant relationship with male gender (p = 0.000). The prevalence of high alcohol use is low in the sample of urban communities studied, and factors influencing include sex, marital status, level of education, income. These results should inform policy decisions to address the alcohol use in urban communities in Southwest Nigeria.

Blood markers of endothelial dysfunction and their correlation to cerebrovascular reactivity in patients with chronic hepatitis C infection

Although liver cirrhosis and hepatocellular carcinoma are major consequences of hepatitis C (HCV), there has been an increasing number of studies examining extrahepatic manifestations, especially those caused by systemic chronic inflammation and metabolic complications that might predispose HCV patients to atherosclerosis and ischemic cerebrovascular disease (CVD). The aim of our study was to assess E-selectin, VCAM-1, ICAM-1 and VEGF-A serum levels in patients with chronic HCV infection and to correlate them with cerebrovascular reactivity. A blood sample was taken from eighteen patients with chronic hepatitis C infection and from the same number of healthy blood donors in the control group. The aim was to analyse markers of endothelial dysfunction and to correlate them with cerebrovascular reactivity expressed as breath-holding index (BHI) determined using transcranial color Doppler. The obtained results revealed significant differences between the groups in all endothelial markers except for the E selectin. While the ICAM-1 and sVCAM-1 were significantly increased in the hepatitis group, VEGF-A was significantly decreased. A significant reduction of 0.5 (95% CI 0.2, 0.8) in the mean BHI was found in the hepatitis group (mean BHI 0.64) compared to controls (mean BHI 1.10). No significant association between the BHI and any of the endothelial markers was found in the control group, while in the hepatitis group, the scatter plot of ICAM-1 vs BHI suggested that the association might be present. In conclusion, the results of this study confirm an association between a chronic HCV infection and altered cerebrovascular reactivity as well as higher levels of markers of endothelial activation (ICAM-1, VCAM-1) as possible indicators of an increased CVD risk.

The J-shaped curve-conceptual and methodological challenges

Purpose

The purpose of this paper is to review the conceptual and methodological challenges of a J-shaped association between alcohol consumption (AC), coronary heart disease (CHD) and all-cause mortality. In associated papers in this journal, Skovenborg et al., 2021 reviews the evidence for the J-shaped curve, and Ellison et al., 2021 examines the advantages and drawbacks of Mendelian randomization studies of the J-shaped curve.

Design/methodology/approach

A number of methodological problems are common in observational research in general, and some of the methodological problems suggested for the J-shaped alcohol-CHD-associations are discussed. The extent of the methodological problems in studies of the J-shaped curve is reviewed, and the possibility that the J-shaped curve is an artifact created by reverse causality and residual confounding is discussed. Further, the issue of interaction with drinking pattern and type of alcohol is discussed.

Findings

Imprecise categorization of alcohol intake information seems to have had little effect on the J-shaped alcohol-CHD-associations, nor has it affected the ability of these studies to show increasing mortality from a range of causes with increasing AC. The problem of “sick quitters” has been resolved by large studies using lifelong abstainers or infrequent drinkers as reference group. Many studies lack information on drinking patterns with regard to regular, moderate consumption versus binge drinking. Stratified analyses by important risk factors for CHD have not significantly changed the J-shaped association observed in most epidemiologic studies.

Originality/value

Potential biases and residual confounding probably do not overcome the J-shaped alcohol-CDH-association observed in most epidemiologic studies; however, the existence of a J-shaped curve is challenged by some degree of uncertainty. The actual review together with the associated papers by Skovenborg et al., 2021 and Ellison et al., 2021 offers a possibility to “update your priors” and achieve greater certainty when giving your patients information on the pros and cons of alcohol intake.

Promoting Successful Cognitive Aging: A Ten-Year Update

A decade has passed since we published a comprehensive review in this journal addressing the topic of promoting successful cognitive aging, making this a good time to take stock of the field. Because there have been limited large-scale, randomized controlled trials, especially following individuals from middle age to late life, some experts have questioned whether recommendations can be legitimately offered about reducing the risk of cognitive decline and dementia. Despite uncertainties, clinicians often need to at least make provisional recommendations to patients based on the highest quality data available. Converging lines of evidence from epidemiological/cohort studies, animal/basic science studies, human proof-of-concept studies, and human intervention studies can provide guidance, highlighting strategies for enhancing cognitive reserve and preventing loss of cognitive capacity. Many of the suggestions made in 2010 have been supported by additional research. Importantly, there is a growing consensus among major health organizations about recommendations to mitigate cognitive decline and promote healthy cognitive aging. Regular physical activity and treatment of cardiovascular risk factors have been supported by all of these organizations. Most organizations have also embraced cognitively stimulating activities, a heart-healthy diet, smoking cessation, and countering metabolic syndrome. Other behaviors like regular social engagement, limiting alcohol use, stress management, getting adequate sleep, avoiding anticholinergic medications, addressing sensory deficits, and protecting the brain against physical and toxic damage also have been endorsed, although less consistently. In this update, we review the evidence for each of these recommendations and offer practical advice about behavior-change techniques to help patients adopt brain-healthy behaviors.

Dietary fat and alcohol in the prediction of indices of vascular health among young adults

OBJECTIVES

Arterial stiffness, particularly of the aorta, is an independent predictor of future cardiovascular disease, all-cause mortality, and hypertension. Arterial stiffening may be caused or exacerbated by the composition of the diet. Current research has indicated that habitual dietary patterns may influence arteriosclerosis, or the thickening and hardening of the artery walls, but has yet to identify a specific food group as the culprit. In young, college-aged adults, dietary fat intake and alcohol consumption tend to be higher compared to other periods throughout the life cycle. Therefore, the purpose of this study was to determine the influence of dietary fat and alcohol consumption on the vascular health of apparently healthy young adults.

METHODS

The data collected were assessed to determine if dietary fat and alcohol in young (18-30 y), college-aged adults (n = 50) were independent predictors of an increase in arterial stiffening. Vascular health was determined by the carotid-femoral pulse-wave velocity and the augmentation index corrected for a heart rate of 75 beats/min; dietary patterns were assessed using the Dietary Health Questionnaire II.

RESULTS

The gold standard marker of aortic stiffness, carotid femoral pulse-wave velocity, was positively correlated with cheese consumption (R² = 0.092, P = 0.033), alcohol consumption (R² = 0.102, P = 0.024), and total energy/calories (%) from alcohol (R² = 0.118, P = 0.015) in univariate analysis. In forward-selection multiple regression analysis, energy from alcohol and cheese consumption accounted for 23.7% of the variance in carotid-femoral pulse-wave velocity (P = 0.009). The augmentation index wave reflection marker was positively correlated with total dietary fat (R² = 0.110, P = 0.019), trans fatty acids (R² = 0.092, P = 0.032), saturated fatty acids (R² = 0.124, P = 0.012), monounsaturated fatty acids (R² = 0.012, P = 0.015), red-meat consumption (R² = 0.094, P = 0.030), and discretionary fat from solids in univariate analysis (R² = 0.137, P = 0.008). Discretionary fat from solids accounted for 13.7% of the variation in augmentation index in forward-selection multiple regression analysis (P = 0.008).

CONCLUSIONS

These results indicate the potential roles of dietary fat and alcohol consumption in early vascular aging by stiffening the arteries of young, college-aged adults, which may in turn contribute to future adverse cardiovascular disease outcomes.

Leisure-Time Physical Activity and Mortality in CKD: A 1999-2012 NHANES Analysis

BACKGROUND

For patients with CKD, evidence on the optimal dose of physical activity and possible harm with excessive exercise is limited. This study aimed to analyze the dose-response association between leisure-time physical activity (LTPA) and mortality in those with CKD and explore the optimal dose or possible harm associated with increased levels of LTPA.

METHODS

4,604 participants with CKD from the 1999 to 2012 National Health and Nutrition Examination Surveys with linked mortality data obtained through 2015 were classified into 6 groups: 0, 1-149, 150-299, 300-599, 600-899, and ≥900 min/week based on the total duration of the self-reported LTPA. Multivariable-adjusted Cox proportional hazards models were used to examine dose-response associations between LTPA and mortality.

RESULTS

During the median follow-up of 114 months, 1,449 (31%) all-cause deaths were recorded. Compared to the inactive group (0 min/week), we observed a 22% lower risk of all-cause mortality (hazard ratio [HR], 0.78; 95% confidence interval [CI], 0.63-0.97) among participants who performed 1-149 min per week for LTPA. The corresponding HRs and 95% CIs for all-cause mortality for 150-299 and 300-599 min/week of LTPA were 0.79 (0.64-0.97) and 0.74 (0.56-0.98). The benefit appeared to reach a threshold of a 43% (HR, 0.57; 95% CI, 0.36-0.91) lower risk of all-cause mortality among individuals performing 600-899 min/week for LTPA. Importantly, for ≥900 min/week of LTPA, the continued benefits were observed (HR, 0.62; 95% CI, 0.44-0.87).

CONCLUSION

LTPA was associated with lower mortality in those with CKD. The optimal dose was observed at the LTPA level of approximately 600-899 min/week, and there were still benefits rather than the excess risk with LTPA levels as high as ≥900 min/week. Therefore, clinicians should encourage inactive CKD patients to perform LTPA and do not need to discourage CKD patients who already adhere to long-term physical activity.

Alcohol-Related Disparities Among Women: Evidence and Potential Explanations

Although research on alcohol-related disparities among women is a highly understudied area, evidence shows that racial/ethnic minority women, sexual minority women, and women of low socioeconomic status (based on education, income, or residence in disadvantaged neighborhoods) are more likely to experience alcohol-related problems. These problems include alcohol use disorder, particularly after young adulthood, and certain alcohol-related health, morbidity, and mortality outcomes. In some cases, disparities may reflect differences in alcohol consumption, but in other cases such disparities appear to occur despite similar and possibly lower levels of consumption among the affected groups. To understand alcohol-related disparities among women, several factors should be considered. These include age; the duration of heavy drinking over the life course; the widening disparity in cumulative socioeconomic disadvantage and health in middle adulthood; social status; sociocultural context; genetic factors that affect alcohol metabolism; and access to and quality of alcohol treatment services and health care. To inform the development of interventions that might mitigate disparities among women, research is needed to identify the factors and mechanisms that contribute most to a group's elevated risk for a given alcohol-related problem.

Association of Liver Transaminase Levels and Long-Term Blood Pressure Variability in Military Young Males: The CHIEF Study

Background: An inverse relationship of serum liver transaminases and mortality might be due to better blood pressure control in hypertensive patients. Whether it holds true regarding such an association for long-term blood pressure variability (BPV) in those without antihypertensive therapy is unclear. Methods: A population of 1112 military males without antihypertensive medications, aged 32 years, was collected from a retrospective longitudinal study in Taiwan. Serum liver aspartate and alanine transaminase (AST and ALT) levels were obtained from a 12 h-fast blood sample of each participant. BPV was assessed by standard deviation (SD) and average real variability (ARV) of systolic and diastolic blood pressure (SBP and DBP), respectively across 4 visits during the study period (2012–2014, 2014–2015, 2015–2016, and 2016–2018). Multivariable linear regression analysis was utilized to determine the association adjusting for demographics, anthropometric indexes, SBP, DBP, and lipid profiles. Results: In the unadjusted model, ALT was significantly and positively correlated with SD_DBP and ARV_DBP (β (standard errors) = 0.36 (0.16) and 0.24 (0.12), respectively), and so was AST (β = 0.19 (0.08) and 0.14 (0.06), respectively). All the associations were insignificant with adjustments. However, ALT was significantly and negatively correlated with SD_SBP and ARV_SBP (β = −0.35 (0.14) and −0.25 (0.11), respectively) and so was AST (β = −0.14 (0.07) and −0.12 (0.06), respectively) with adjustments. Conclusion: Our findings suggested that serum liver transaminases were negatively correlated with long-term systolic BPV in young male adults without antihypertensive therapy, and the clinical relevance needs further investigations.

The impact of lifestyle behaviours, physical activity and smoking on morbidity and mortality in patients with rheumatoid arthritis

Rheumatoid arthritis (RA) is associated with pain, disability and increased risk of developing comorbidities and premature mortality. While these poor outcomes have improved in line with advances in the treatment of RA, they still persist to some degree today. Physical activity and smoking are two areas of patients' lives where changes may have a substantial impact on the poor outcomes associated with RA. Physical activity in RA has been well studied, with many randomised trials indicating the benefits of physical activity on pain and disability. A number of observational studies have assessed the impact of smoking on RA, also indicating the benefits of quitting smoking on RA-related outcomes, but with less consistent findings, potentially due to epidemiological challenges (e.g. collider bias, recall bias). There are also a number of barriers preventing patients making these positive lifestyle changes, such as lack of time and motivation, lack of knowledge and advice, as well as disease-specific barriers, such as pain and fatigue.

The role of physical activity in the association between multimorbidity and depressive symptoms: Data from 60,202 adults from the Brazilian National Health Survey

OBJECTIVE

Depression is commonly associated to physical multimorbidity and there is an urgent need to identify modifiable risk factors. Physical activity (PA) is good for health, but the association between PA and multimorbidity with depressive symptoms is unclear. Thus, we investigated whether meeting weekly recommended PA guidelines influences the association between multimorbidity and depressive symptoms.

METHODS

Data were used from a national survey conducted in Brazil in 2013 with 60,202 adults (≥ 18 years). Information regarding depressive symptoms (PHQ-9), PA, and chronic disease was collected via interview-administered questionnaires. Data on covariates (age, educational status, employment status, tobacco smoking, alcohol consumption, and TV-viewing) were also assessed. Adjusted logistic regression models were used.

RESULTS

Overall, men and women with one or more chronic conditions who were inactive (engaging in <150 min PA per week) had higher odds of elevated depressive symptoms than active individuals with no chronic condition. However, only in men, physical inactivity interacts with heart disease (OR: 2.59; 95%CI: 1.10 to 6.09), cancer (OR: 21.54; 95%CI: 2.67 to 173.94) and chronic obstructive pulmonary disease (COPD) (OR: 8.26; 95%CI: 2.20 to 31.01) regarding elevated depressive symptoms.

CONCLUSION

Our data suggest that engaging in weekly recommended PA targets may attenuate association of heart disease, cancer and COPD with depressive symptoms among men.

The Association between Health Insurance and All-Cause, Cardiovascular Disease, Cancer and Cause-Specific Mortality: A Prospective Cohort Study

The purpose of this study was to evaluate the association of insurance status with all-cause and cause-specific mortality. A total of 390,881 participants, aged 18-64 years and interviewed from 1997 to 2013 were eligible for a mortality follow-up in December 31, 2015. Cox proportional hazards models were used to calculate the hazards ratios (HR) and 95% confidence intervals (CI) to determine the association between insurance status and all-cause and cause-specific mortality. The sample group cumulatively aged 4.22 million years before their follow-ups, with a mean follow-up of 10.4 years, and a total of 22,852 all-cause deaths. In fully adjusted models, private insurance was significantly associated with a 17% decreased risk of mortality (HR = 0.83; 95% CI = 0.80-0.87), but public insurance was associated with a 21% increased risk of mortality (HR = 1.21; 95% CI = 1.15-1.27). Compared to noninsurance, private coverage was associated with about 21% lower CVD mortality risk (HR = 0.79, 95% CI = 0.70-0.89). In addition, public insurance was associated with increased mortality risk of kidney disease, diabetes and CLRD, compared with noninsurance, respectively. This study supports the current evidence for the relationship between private insurance and decreased mortality risk. In addition, our results show that public insurance is associated with an increased risk of mortality.

Association between employment status and risk of all-cause and cause-specific mortality: a population-based prospective cohort study

Background

Unemployment has been reported to be associated with an increased risk of mortality. While most available studies focused on the effects of temporary unemployment on mortality, it remains unclear whether similar trends can be found in subjects who were never employed or are retirement. Therefore, this study examined the associations between temporary unemployment, never employed and retirement, integrating the risk of all-cause and cause-specific mortality in US adults.

Methods

Data from the National Health Interview Survey from 2001 to 2013 Linked Mortality files through 31 December 2015 were used. A total of 282 364 participants aged 18 to 65 years were included. Their employment status was categorised into four groups: employed, never employed, temporary unemployed and retired.

Results

During the mean follow-up time of 8.2 years, 12 645 subjects died from a variety of causes. Compared with employed participants, temporary unemployed, never employed or retired participants faced an increased risk of mortality for all-cause (temporary unemployed HR 1.76, 95% CI 1.67 to 1.86; never employed HR 1.63, 95% CI 1.47 to 1.81; retired HR 1.27, 95% CI 1.17 to 1.37). Cause-specific mortality analysis showed that compared with employed participants, temporary unemployed or never employed participants faced a significantly increased risk of mortality from cancer, cardiovascular disease, chronic lower respiratory disease, diabetes and kidney disease.

Conclusion

This study showed that retired, temporary unemployed and never employed participants aged 18 to 65 years were strongly associated with higher mortality, indicating that both temporary and long-term unemployment are associated with a higher risk of mortality and adversely affect longevity.

Clarifying the neurobehavioral sequelae of moderate drinking lifestyles and acute alcohol effects with aging

Epidemiological estimates indicate not only an increase in the proportion of older adults, but also an increase in those who continue moderate alcohol consumption. Substantial literatures have attempted to characterize health benefits/risks of moderate drinking lifestyles. Not uncommonly, reports address outcomes in a single outcome, such as cardiovascular function or cognitive decline, rather than providing a broader overview of systems. In this narrative review, retaining focus on neurobiological considerations, we summarize key findings regarding moderate drinking and three health domains, cardiovascular health, Type 2 diabetes (T2D), and cognition. Interestingly, few investigators have studied bouts of low/moderate doses of alcohol consumption, a pattern consistent with moderate drinking lifestyles. Here, we address both moderate drinking as a lifestyle and as an acute event. Review of health-related correlates illustrates continuing inconsistencies. Although substantive reductions in risk for cardiovascular and T2D events are reported, robust conclusions remain elusive. Similarly, whereas moderate drinking is often associated with enhanced cognition and lower dementia risk, few benefits are noted in rates of decline or alterations in brain structure. The effect of sex/gender varies across health domains and by consumption levels. For example, women appear to differentially benefit from alcohol use in terms of T2D, but experience greater risk when considering aspects of cardiovascular function. Finally, we observe that socially relevant alcohol doses do not consistently impair performance in older adults. Rather, older drinkers demonstrate divergent, but not necessarily detrimental, patterns in neural activation and some behavioral measures relative to younger drinkers. Taken together, the epidemiological and laboratory studies reinforce the need for greater attention to key individual differences and for the conduct of systematic studies sensitive to age-related shifts in neurobiological systems.

Compared to non-drinkers, individuals who drink alcohol have a more favorable multisystem physiologic risk score as measured by allostatic load

Aims

Alcohol use is associated with both positive and negative effects on individual cardiovascular risk factors, depending upon which risk factor is assessed. The present analysis uses a summative multisystem index of biologic risk, known as allostatic load (AL), to evaluate whether the overall balance of alcohol-associated positive and negative cardiovascular risk factors may be favorable or unfavorable.

Methods

This analysis included 1255 adults from the Midlife in the United States (MIDUS) biomarker substudy. Participants, average age 54.5 (±11) years, were divided into 6 alcohol-use categories based on self-reported drinking habits. Current non-drinkers were classified as lifelong abstainers and former light drinkers, former moderate drinkers, or former heavy drinkers. Current alcohol users were classified as light, moderate, or heavy drinkers. A total AL score was calculated using 24 biomarkers grouped into 7 physiologic systems including cardiovascular, inflammation, glucose metabolism, lipid metabolism, sympathetic and parasympathetic nervous systems, and the hypothalamic-pituitary-adrenal axis. Mixed-effects regression models were fit to determine the relationship between alcohol use categories and AL with controls for covariates that may influence the relationship between alcohol use and AL.

Results

468 (37.6%) individuals were current non-drinkers while 776 (62.4%) were current drinkers. In adjusted mixed-effects regression models, all 3 groups of current drinkers had significantly lower average AL scores than the lifelong abstainer/former light drinker group (light: -0.23, 95% CI -0.40, -0.07, p < 0.01; moderate: -0.20, 95% CI -0.38, -0.02, p < 0.05; heavy: -0.30, 95% CI -0.57, -0.04, p < 0.05), while the average AL scores of former moderate and former heavy drinkers did not differ from the lifelong abstainer/former light drinker group.

Conclusions

Current alcohol use is associated cross-sectionally with a favorable multisystem physiologic score known to be associated with better long-term health outcomes, providing evidence in support of long-term health benefits related to alcohol consumption.

Alcohol, health and cardiovascular disease

Recent epidemiological studies have shown that alcohol consumption can increase the risk of arterial hypertension, atrial fibrillation and gastrointestinal and breast cancer. Various sectors are therefore promoting abstinence from alcohol. However, light alcohol consumption has once again been shown to reduce the risk of myocardial infarction and diabetes but with an unclear effect on cerebrovascular disease. The decision to consume alcohol should therefore be an individual one based on personal factors. A level of consumption <100 g/week for men (less for women) appears not to increase all-cause mortality, while high consumption or binge drinking significantly increases mortality risk. All measures to prevent this type of consumption, especially among the younger population, should therefore be applied. There are data indicating an advantage of wine over other beverages, but they are not conclusive.

Association between hours worked in paid employment and diet quality, frequency of eating out and consuming takeaways in the UK

OBJECTIVE

To examine associations between hours worked and diet quality, frequency of eating out and consuming takeaways.

DESIGN

Data were taken from the National Diet and Nutrition Survey (2008-2014). Associations between hours worked in paid employment and diet quality, assessed using the Diet Quality Index (DQI) and selected foods and nutrients, were tested using linear regression models. Associations between hours worked and frequency of eating out and consuming takeaways were tested using ordinal logistic regression models. All models were adjusted for sex, age, equivalised household income, household composition and household food role.

SETTING

UK.

PARTICIPANTS

Adults (n 2154) aged 19-64 years in employment.

RESULTS

Mean (95 % CI) hours worked per week was 36·1 (35·6, 36·6) and mean DQI score was 41·9 (41·2, 42·5) %. Hours worked was not associated with DQI score, frequency of eating out or consuming takeaways. Hours worked was positively associated with consuming red meat, processed meat and alcohol intake. Adults working more hours had lower intake of fibre but higher total fat and saturated fat intakes if they lived in households with children.

CONCLUSIONS

Working hours may not be the main factor driving poor-quality diets among this sample of UK adults in employment. Focusing on consumption of foods prepared outside the household may not be the most efficient way to improve diet quality as effort is needed at all levels. Although it is unclear what is driving the differences in nutrient intakes according to household composition, they are important to consider when developing interventions to improve healthy eating.

Guideline-conform statin use reduces overall mortality in patients with compensated liver disease

Statins reduce cardiovascular risk. However, “real-life” data on statin use in patients with chronic liver disease and its impact on overall and liver-related survival are limited. Therefore, we assessed 1265 CLD patients stratified as advanced (ACLD) or non-advanced (non-ACLD) stage. Statin indication was evaluated according to the 2013 ACC/AHA guidelines and survival-status was verified by national death registry data. Overall, 122 (9.6%) patients had an indication for statin therapy but did not receive statins, 178 (14.1%) patients were on statins and 965 (76.3%) patients had no indication for statins. Statin underutilization was 34.2% in non-ACLD and 48.2% in ACLD patients. In non-ACLD patients, survival was worse without a statin despite indication as compared to patients on statin or without indication (log-rank p = 0.018). In ACLD patients, statin use did not significantly impact on survival (log-rank p = 0.264). Multivariate cox regression analysis confirmed improved overall survival in patients with statin as compared to patients with indication but no statin (HR 0.225; 95%CI 0.053–0.959; p = 0.044) and a trend towards reduced liver-related mortality (HR 0.088; 95%CI 0.006–1.200; p = 0.068). This was not observed in ACLD patients. In conclusion, guideline-confirm statin use is often withhold from  patients with liver disease and this underutilization is associated with impaired survival in non-ACLD patients.

Cardiovascular Disease and Homelessness

Cardiovascular disease (CVD) is a major cause of death among homeless adults, at rates that exceed those in nonhomeless individuals. A complex set of factors contributes to this disparity. In addition to a high prevalence of cigarette smoking and suboptimal control of traditional CVD risk factors such as hypertension and diabetes, a heavy burden of nontraditional psychosocial risk factors like chronic stress, depression, heavy alcohol use, and cocaine use may confer additional risk for adverse CVD outcomes beyond that predicted by conventional risk estimation methods. Poor health care access and logistical challenges to cardiac testing may lead to delays in presentation and diagnosis. The management of established CVD may be further challenged by barriers to medication adherence, communication, and timely follow-up. The authors present practical, patient-centered strategies for addressing these challenges, emphasizing the importance of multidisciplinary collaboration and partnership with homeless-tailored clinical programs to improve CVD outcomes in this population.

Effect of Alcohol Consumption on Survival in Nonalcoholic Fatty Liver Disease: A National Prospective Cohort Study

Nonalcoholic fatty liver disease (NAFLD) comprises more than two thirds of patients with chronic liver disease in the United States. The effect of alcohol consumption on survival in patients with NAFLD is not clear. We gathered data on National Health and Nutrition Examination Survey participants from 1988 to 2010, and linked them to the National Death Index for follow-up of their survival. We diagnosed NAFLD based on a previously validated biochemical model (Hepatic Steatosis Index). We built multivariate Cox proportional hazards models to evaluate the effect of alcohol consumption on survival of patients with NAFLD. After excluding participants with significant alcohol use, viral hepatitis, or increased transferrin saturation, 4,568 participants with NAFLD were included in the analysis. In a Cox model adjusted for age, sex, and smoking history, drinking 0.5-1.5 drinks per day decreased the risk of overall mortality by 41% (hazard ratio [HR] = 0.59, 95% confidence interval [CI] 0.40-0.85, P = 0.005) compared with not drinking. Drinking ≥1.5 drinks per day showed a trend toward harm (HR = 1.16, 95% CI 0.99-1.36, P = 0.119). After further adjustment for race, physical activity, education level, diabetes, and fiber and polyunsaturated fatty acid intake, drinking 0.5-1.5 drinks per day continued to show a significant protective effect (HR = 0.64, 95% CI 0.42-0.97, P = 0.035), and drinking ≥1.5 drinks per day showed a significant harmful effect on mortality (HR = 1.45, 95% CI 1.01-2.10, P = 0.047). Among patients with NAFLD, modest alcohol consumption is associated with a significant decrease in all-cause mortality, whereas drinking ≥1.5 drinks per day is associated with an increase in mortality. These results help to inform the discussion of potential risks and benefits of alcohol use in patients with NAFLD.

Evaluation of cerebrovascular reactivity in chronic hepatitis C patients using transcranial color Doppler

Hepatitis C viral (HCV) infection is associated with systemic inflammation and metabolic complications that might predispose patients to atherosclerosis, including cerebrovascular atherosclerosis. The aim of this study was to assess cerebrovascular reactivity in patients with chronic hepatitis C. Seventeen patients with chronic hepatitis C infection, as well as 11 healthy blood donors in the control group, were assessed for cerebrovascular reactivity according to the well-established breath-holding test that uses the transcranial color Doppler for measurement of blood flow velocity. Results obtained during the breath-holding revealed significantly lower average peak systolic (AvPS start, P = 0.018), end-diastolic (AvED start, P = 0.031) and mean velocity values at the very beginning of the breath-holding procedure (AvmeanV start, P = 0.02), as well as a lower mean peak systolic velocity at the end of the breath-holding test (AvPS max, P = 0.02) in the hepatitis C group. Vascular reactivity values, calculated as the breath-holding index, were also significantly lower (P = 0.045) in the hepatitis C group. In conclusion, the results of this study suggest an association between chronic HCV infection and altered cerebrovascular reactivity which may ultimately have an unfavorable effect on cerebrovascular hemodynamics and lead to increased risk of cerebrovascular diseases.

Effects of ethanol and ethanol metabolites on intrinsic function of mesenteric resistance arteries

Evidence suggests that ethanol-induced hypertension is associated with increased cardiovascular responsiveness to vasopressors in vivo and enhanced reactivity of isolated arteries to vasopressors ex vivo. The underlying mechanisms are not well understood and the contribution of ethanol metabolites to vascular effects induced by ethanol consumption are unclear. Mesenteric resistance arteries were harvested from Sprague-Dawley rats. Pressure myography was utilized to test effects of ethanol, acetaldehyde and phosphatidylethanol on myogenic tone and on vasoconstriction induced by phenylephrine, arginine vasopressin (aVP), endothelin-1 and KCl. Ethanol, acetaldehyde and phosphatidylethanol concentrations were monitored during the experiments. Ethanol concentrations in the vessel bath decreased with a half-life of 25min; acetaldehyde and phosphatidylethanol concentrations remained constant. Pretreatment with ethanol dose-dependently increased the potency of phenylephrine to induce vasoconstriction 4-fold (p<0.01). These effects were comparable when arteries were pre-treated with a single dose of ethanol for 30min and when ethanol concentrations were kept constant during 30min and 60min of pretreatment. While ethanol also dose-dependently increased the potency of aVP to induce vasoconstriction 1.7-fold (p<0.05), it did not affect vasoconstriction induced by endothelin-1 or KCl. Acetaldehyde pre-treatment (30 min) dose-dependently increased the potency of phenylephrine to induce vasoconstriction 2.7-fold (p<0.01) but did not affect other vasoconstrictor responses. Phosphatidylethanol did not affect any vasoconstrictor responses. Ethanol and its metabolites did not affect myogenic tone. These data suggest that ethanol and acetaldehyde selectively sensitize intrinsic constrictor responses upon activation of vascular α₁-adrenergic and/or vasopressin receptors at clinically relevant concentrations. Our findings support the concept that enhanced vasoreactivity to vasoactive hormones contributes to the development of hypertension induced by ethanol consumption. Ex vivo exposure of resistance arteries to ethanol and acetaldehyde resembles effects of chronic ethanol consumption on intrinsic vascular function, and thus could serve as test platform to evaluate interventions aimed to mitigate vascular effects associated with ethanol consumption.
