Sex-Specific Associations Between Alcohol Consumption and Incidence of Hypertension: A Systematic Review and Meta-Analysis of Cohort Studies

Alcohol and Binge Drinking Frequency and Hypertension: A National Cross-Sectional Study in the U.S

INTRODUCTION

The relationship between alcohol consumption and hypertension is multifaceted and a major public health concern. The association becomes even more complicated when hypertension is undiagnosed. This study investigates how alcohol consumption patterns are linked to measured, diagnosed, undiagnosed, and composite hypertension (any indications of hypertension from blood pressure readings, professional diagnosis, or reported medication use) in the United States.

METHODS

Data from the National Health and Nutrition Examination Survey 2015-2020, a nationally representative cross-sectional study, were analyzed in 2023-2024. The final analytic sample was 12,950 participants. Complex-survey weighted multivariable linear and logistic regression models estimated the effect of different alcohol consumption levels on hypertension.

RESULTS

Descriptive findings show that those who consumed alcohol more than 3 times weekly exhibited the highest prevalence of measured (52.5%), undiagnosed (27.0%), and composite hypertension (69.4%) compared to other levels of alcohol drinking. Multivariable linear regression analysis indicated a notable elevation in systolic (4.8 unit) and diastolic (2.46 unit) blood pressure among individuals with frequent binge drinking episodes compared to individuals with infrequent drinking. Logistic regression models estimated that drinking over 3 times weekly increases the odds of measured, undiagnosed, and composite hypertension by 64%, 70%, and 54%, respectively, while frequent binge drinking episodes raise these odds by 82%, 65%, and 47%.

CONCLUSIONS

Contrary to some studies suggesting moderate alcohol intake has protective cardiovascular effects, the findings did not corroborate a "J-shaped" curve. This underscores the importance of regular blood pressure monitoring among individuals with binge drinking episodes and emphasizes the need for public health interventions to mitigate alcohol consumption and its associated hypertension risks.

The association between the urinary chromium and blood pressure: a population-based study

BACKGROUND AND AIM

The impact of trace elements and heavy metals on human health has attracted widespread attention. However, the correlation between urinary chromium concentrations and blood pressure remains unclear and inadequately reported, and the aim of this study was to investigate the relationship between urinary chromium concentrations and blood pressure in adults in the United States (US).

METHODS

We utilized data from the National Health and Nutrition Examination Survey (NHANES) 2017-2018 for this study. Multivariate logistic regression and multivariate linear regression were used to explore the association of urinary chromium concentrations with hypertension and blood pressure. Additionally, we also performed subgroup analysis and restricted cubic splines (RCS).

RESULTS

A total of 2958 participants were enrolled in this study. The overall mean systolic blood pressure and diastolic blood pressure were 123.98 ± 0.60, 72.66 ± 0.57 mmHg, respectively. The prevalence of hypertension was found in 41.31% of the whole participants. In the fully adjusted model, we did not observe a correlation between urinary chromium concentrations and the risk of hypertension and systolic blood pressure. However, we found a negative association between urinary chromium concentrations and diastolic blood pressure. In subgroup analysis, we observed a positive association between urinary chromium and the risk of hypertension among participants older than 60 years of age and those who were Non-Hispanic Black. The interaction term highlighted the influence of age and race on this positive association. We also found a negative association of urinary chromium with diastolic blood pressure in male, participants who were current smokers, overweight, and other races, as well as those without alcohol use and anti-hypertensive drug use. However, the interaction term only revealed the influence of alcohol consumption on the negative association.

CONCLUSION

Our study suggested that urinary chromium concentrations may show a negative association with diastolic blood pressure and this association was significantly dependent on alcohol consumption. Besides, a positive association between urinary chromium and the risk of hypertension was also found among participants older than 60 years of age and those who were Non-Hispanic Black.

Stakeholder-Informed Solutions To Address Barriers for Alcohol Screening and Brief Intervention in Thai Hypertension Care

Premature deaths from NCDs disproportionately affect people in low- and middle-income countries. Since alcohol use is one of the most common causes of reversible hypertension, interventions targeting alcohol use may be a feasible and effective low-cost approach to synergistically reduce the prevalence of harmful drinking and high blood pressure. This study sought to identify key factors in successfully implementing alcohol use screening and brief intervention in hypertension care in Thailand. For this purpose, we surveyed participants (NRound 1 = 91, NRound 2 = 27) from three different groups of Thai stakeholders (policy- and decisionmakers, primary healthcare practitioners, and patients diagnosed with hypertension) in a two-round stakeholder elicitation. In round 1, we identified limited resources, lack of clear guidelines for lifestyle intervention, stigmatization, and inconsistent monitoring of patients' alcohol use as important barriers. In round 2, we sought to elicit solutions for the barriers identified in round 1. While stakeholders emphasized the need for adaptability to existing realities in Thai primary healthcare such as a high workload and limited digitization, they favorably evaluated a digital alcohol assessment tool with integrated, tailored advice for brief intervention as a potential scalable solution. Findings suggest that as one possible route to reduce the NCD burden caused by hypertension in Thailand, primary healthcare services may be enhanced by digital tools that support resource-effective, intuitive, and seamless delivery of alcohol screening and brief intervention.

Is coffee, tea, and red wine consumption beneficial for individuals with hypertension?

OBJECTIVE

To investigate the associations of tea, coffee, and red wine intakes with health risks among individuals with hypertension.

METHODS

This prospective cohort study included participants with hypertension from the UK Biobank cohort. Study exposures included self-reported intakes of coffee, tea, and red wine. The primary outcome was all-cause mortality, and the secondary outcomes were cardiovascular mortality and cardiovascular disease. The associations of beverage intake with outcomes were analyzed using Cox regression models. The hazard ratios and 95% confidence intervals were estimated.

RESULTS

A total of 187 708 participants with hypertension were included. The median follow-up period was 13.8 years. In individuals with hypertension, drinking one to two cups/day of coffee or three to four cups/day of tea was significantly associated with the lowest risk of all-cause mortality compared with less than one cup/day [hazard ratio for coffee, 0.943 (95% confidence interval, 0.908-0.979); hazard ratio for tea, 0.882 (95% confidence interval, 0.841-0.924)]. Red wine intake was inversely associated with all-cause mortality risk. Dose-response analysis revealed that high coffee intake (approximately greater than or equal to six cups/day) was significantly associated with increased risks of cardiovascular mortality and cardiovascular disease, but high tea and red wine intakes were not. Furthermore, replacing plain water with tea, but not coffee, significantly reduced the risks of all-cause mortality and cardiovascular disease. Replacing other alcoholic beverages with red wine also significantly reduced the risks of all three outcomes.

CONCLUSIONS

These findings suggest that tea and red wine, but not coffee, can be part of a healthy diet for the hypertensive population.

Different minimal alcohol consumption in male and female individuals with metabolic dysfunction-associated fatty liver disease

BACKGROUND AND AIMS

The relationship between moderate alcohol intake and health outcomes among individuals with metabolic dysfunction-associated fatty liver disease (MAFLD) is complex. Our aim was to investigate the association of minimal alcohol consumption with all-cause and cause-specific mortality among MAFLD individuals of different genders.

METHODS

Our study included 2630 MAFLD individuals from the Third National Health and Nutrition Examination Survey. Cox regression analysis was performed to assess the association between alcohol use measures and all-cause and cause-specific mortality. Restricted cubic spline curves were used to evaluate the relationship between alcohol consumption per week and all-cause mortality.

RESULTS

In the entire MAFLD cohort, we observed significant disparities in clinical characteristics between male and female individuals with MAFLD. Higher weekly alcohol consumption was significantly associated with all-cause and cause-specific mortality (male, hazard ratios [HRs]: 1.009, 95% CIs: 1.004-1.014; female, HRs: 1.032, 95% CIs: 1.022-1.042). In males with MAFLD, a linear association with all-cause mortality was observed for weekly alcohol consumption (p for non-linearity = .21). Conversely, in females with MAFLD, the risk of all-cause mortality remained relatively stable until 2 drinks per week, after which it rapidly increased with each additional drink consumed, and the increase in mortality risk was higher than that observed in males (p for non-linearity < .05).

CONCLUSIONS

Our findings indicate that any increase in weekly alcohol consumption was associated with increased all-cause mortality in men with MAFLD. Conversely, consuming less than 2 drinks per week had minimal impact on the risk of mortality among female.

The Role of Diet in the Prevention of Hypertension and Management of Blood Pressure: An Umbrella Review of Meta-Analyses of Interventional and Observational Studies

High blood pressure (BP) is a major pathological risk factor for the development of several cardiovascular diseases. Diet is a key modifier of BP, but the underlying relationships are not clearly demonstrated. This is an umbrella review of published meta-analyses to critically evaluate the wide range of dietary evidence from bioactive compounds to dietary patterns on BP and risk of hypertension. PubMed, Embase, Web of Science, and Cochrane Central Register of Controlled Trials were searched from inception until October 31, 2021, for relevant meta-analyses of randomized controlled trials or meta-analyses of observational studies. A total of 175 publications reporting 341 meta-analyses of randomized controlled trials (145 publications) and 70 meta-analyses of observational studies (30 publications) were included in the review. The methodological quality of the included publications was assessed using Assessment of Multiple Systematic Reviews 2 and the evidence quality of each selected meta-analysis was assessed using NutriGrade. This umbrella review supports recommended public health guidelines for prevention and control of hypertension. Dietary patterns including the Dietary Approaches to Stop Hypertension and the Mediterranean-type diets that further restrict sodium, and moderate alcohol intake are advised. To produce high-quality evidence and substantiate strong recommendations, future research should address areas where the low quality of evidence was observed (for example, intake of dietary fiber, fish, egg, meat, dairy products, fruit juice, and nuts) and emphasize focus on dietary factors not yet conclusively investigated.

Lifestyle management of hypertension: International Society of Hypertension position paper endorsed by the World Hypertension League and European Society of Hypertension

Hypertension, defined as persistently elevated systolic blood pressure (SBP) >140 mmHg and/or diastolic blood pressure (DBP) at least 90 mmHg (International Society of Hypertension guidelines), affects over 1.5 billion people worldwide. Hypertension is associated with increased risk of cardiovascular disease (CVD) events (e.g. coronary heart disease, heart failure and stroke) and death. An international panel of experts convened by the International Society of Hypertension College of Experts compiled lifestyle management recommendations as first-line strategy to prevent and control hypertension in adulthood. We also recommend that lifestyle changes be continued even when blood pressure-lowering medications are prescribed. Specific recommendations based on literature evidence are summarized with advice to start these measures early in life, including maintaining a healthy body weight, increased levels of different types of physical activity, healthy eating and drinking, avoidance and cessation of smoking and alcohol use, management of stress and sleep levels. We also discuss the relevance of specific approaches including consumption of sodium, potassium, sugar, fibre, coffee, tea, intermittent fasting as well as integrated strategies to implement these recommendations using, for example, behaviour change-related technologies and digital tools.

Factors influencing blood pressure variability in postmenopausal women: evidence from the China Health and Nutrition Survey

BACKGROUND

The aim is to identify the factors influencing blood pressure variability in postmenopausal women based on the China Health and Nutrition Survey (CHNS).

MATERIAL AND METHODS

The data on postmenopausal women between 1993 and 2015 were extracted from the CHNS. Group-based trajectory modeling was used to analyze the development track of blood pressure changes, based on which the subjects were separately divided into two groups for systolic blood pressure (SBP) and diastolic blood pressure (DBP). Univariate and multivariate analyzes were performed to analyze the factors influencing SBP and DBP.

RESULTS

A total of 346 women were eligible for the study. Group-based trajectory modeling showed two different trajectories of blood pressure, including the low-level, slowly developed type and the high-level, rapidly developed, stable type of SBP, as well as the low-level, slowly developed type and the high-level, slowly developed type of DBP. In multivariate analysis, age (odds ratio [OR]: 1.118, 95% confidence interval [CI]: 1.082-1.156), body mass index (BMI) (OR: 2.239, 95%CI: 1.010-4.964), antihypertensive agents (OR: 7.293, 95%CI: 2.191-24.275), hip circumference (OR: 1.069, 95%CI: 1.014-1.128) and marital status (OR: 3.103, 95%CI: 1.028-9.361) were found to be the significant factors influencing SBP; age (OR: 1.067, 95%CI: 1.039-1.096), alcohol consumption (OR: 2.741, 95%CI: 1.169-6.429), antihypertensive agents (OR: 4.577, 95%CI: 1.553-13.492), hip circumference (OR: 1.093, 95%CI: 1.049-1.138), and marital status (OR: 3.615, 95%CI: 1.228-10.644) were the predominant factors influencing DBP.

CONCLUSIONS

In postmenopausal women, age, BMI, antihypertensive agents, hip circumference, and marital status are associated with SBP changes, while age, alcohol consumption, antihypertensive agents, hip circumference, and marital status with DBP variability.

Alcohol intake including wine drinking is associated with decreased platelet reactivity in a large population sample

BACKGROUND

Alcohol consumption is linked to decreased platelet function. Whether this link is dependent on sex or type of beverage remains unclear.

METHODS

Cross-sectional data were obtained from the Framingham Heart Study (N = 3427). Alcohol consumption was assessed by using standardized medical history and Harvard semi-quantitative food frequency questionnaires. Five bioassays measured 120 platelet reactivity traits across agonists in whole-blood and platelet-rich plasma samples. Linear mixed-effects models adjusted for age, sex and aspirin use, hypertension, body mass index, cholesterol, high-density lipoprotein, triglycerides, smoking and diabetes evaluated associations between platelet reactivity and alcohol consumption. Beta effects, the regression coefficients that estimate the amount of change in each unit of the predictor variable whereas all other predictor variables remain fixed, for heavy alcohol consumption were compared with effects of aspirin use.

RESULTS

Alcohol consumption was associated with decreased platelet reactivity, with more associations among wine and liquor compared with beer. Many platelet-alcohol associations in the full sample (86%, P < 0.01) had larger effect sizes in females. Lower light transmission aggregometry adenosine diphosphate (1.82 µM) maximum aggregation (P = 2.6E-3, 95% CI = -0.07, -0.02, β = -0.042) and area under the curve (P = 7.7E-3, 95% CI = -0.07, -0.01, β = -0.039) were associated with white wine consumption; however, red wine had no associations with platelet reactivity. The effect of aspirin use was on average 11.3 (±4.0) times greater than that of heavy drinking in our full sample.

CONCLUSIONS

We confirm associations between alcohol consumption and decreased platelet reactivity. Effects appeared larger for liquor and wine intake and in our female cohort. Red wine consumption is not associated with lower platelet function, contrasting with prior population studies. Although we report an inhibitory relationship between alcohol intake and platelet function, these effects appear much smaller than that of aspirin use.

Abstinence Restores Cardiac Function in Mice with Established Alcohol-Induced Cardiomyopathy

Alcohol-induced cardiomyopathy (ACM) has a poor prognosis with up to a 50% chance of death within four years of diagnosis. There are limited studies investigating the potential of abstinence for promoting repair after alcohol-induced cardiac damage, particularly in a controlled preclinical study design. Here, we developed an exposure protocol that led to significant decreases in cardiac function in C57BL6/J mice within 30 days; dP/dt max decreased in the mice fed alcohol for 30 days (8054 ± 664.5 mmHg/s compared to control mice: 11,188 ± 724.2 mmHg/s, p < 0.01), and the dP/dt min decreased, as well (-7711 ± 561 mmHg/s compared to control mice: -10,147 ± 448.2 mmHg/s, p < 0.01). Quantitative PCR was used to investigate inflammatory and fibrotic biomarkers, while histology was used to depict overt changes in cardiac fibrosis. We observed a complete recovery of function after abstinence (dP/dt max increased from 8054 ± 664 mmHg/s at 30 days to 11,967 ± 449 mmHg/s after abstinence, p < 0.01); further, both inflammatory and fibrotic biomarkers decreased after abstinence. These results lay the groundwork for future investigation of the molecular mechanisms underlying recovery from alcohol-induced damage in the heart.

Association Between Changes in Alcohol Consumption Before and After the Great East Japan Earthquake and Risk of Hypertension: A Study Using the Ministry of Health, Labour and Welfare National Database

BACKGROUND

The 2011 Great East Japan Earthquake has resulted in a nuclear accident, forcing residents of the surrounding areas to evacuate. To determine any association between excessive drinking and hypertension in the setting of disaster, we assessed whether the proportion of excessive drinkers increased and if post-disaster excessive drinking was a risk factor for hypertension.

METHODS

This retrospective study assessed data from the Japanese National Database. Cumulative population data for Fukushima Prefecture (3,497,576 people) were analyzed by categorizing residents into four areas-evacuation, coastal, central, and mountainous-to calculate the proportion of excessive, heavy (equivalent to binge drinking), and at-risk drinkers for 2008-2017. The hazard ratios (HRs) for the incidence of hypertension for 2012-2017 were examined in association with changes in drinking status pre- and post-disaster, which included 136,404 people who received specific health checkups pre-disaster (2008-2010) and post-disaster (2011-2012).

RESULTS

The proportion of excessive drinkers among women increased after the disaster in all areas examined. The association between excessive drinking and the incidence of hypertension was determined among men and women in all areas; it was stronger among women in the evacuation areas, with the sex- and age-adjusted HRs for the incidence of hypertension of 1.41 for pre-disaster excessive drinking, 2.34 for post-disaster excessive drinking, and 3.98 for pre- and post-disaster excessive drinking, compared with not excessive drinking pre- and post-disaster.

CONCLUSION

Excessive drinking post-disaster may be associated with an increased risk of hypertension among men and women, especially among women in the evacuation areas.

Extrahepatic Health Effects of Alcohol Use and Alcohol-associated Liver Disease

PURPOSE

Alcohol use disorder (AUD) is a growing public health concern and an important contributor to global morbidity and mortality. While the hepatotoxic effects of alcohol are well known, the adverse effects of alcohol are manifested in almost every organ system. With the growing public health impact of AUD, the aim of this narrative review is to highlight the epidemiology and burden of AUD and its association with extrahepatic diseases including malignancy and disorders of the gastrointestinal (GI), cardiovascular, immunologic, neurologic, endocrine, and hematologic systems.

METHODS

A narrative review of the literature was performed to identify studies addressing the epidemiology, pathophysiology, clinical manifestations, and therapy of extrahepatic health manifestations of alcohol use.

FINDINGS

In the United States, an estimated 14.5 million people have AUD and approximately 88,000 adults die yearly due to alcohol-related causes. The consumption of alcohol and AUD is associated with injuries, violence, cancers, nonmalignant conditions of the GI system, infections, effects on the cardiovascular system, and neurodegenerative diseases. These conditions contribute to the increased mortality associated with AUD and are burdensome to patients and caregivers.

IMPLICATIONS

Increased awareness of the extrahepatic manifestations of AUD, screening for AUD using validated screening tools, such as the Alcohol Use Disorders Identification Test-Concise (AUDIT-C) score, and offering evidence-based interventions to patients with AUD is imperative to reduce the public health burden of AUD. Although historically controversial, recent evidence suggests that any level of alcohol consumption can have negative health consequences. Further research is warranted to determine if any amount of alcohol is safe for consumption. Public health efforts are warranted to help curtail the growing burden of AUD.

Effect of moderate beer consumption (with and without ethanol) on cardiovascular health in postmenopausal women

BACKGROUND

The main aim of this 2-year non-randomized parallel controlled clinical pilot trial was to evaluate the long-term effect of a moderate daily intake of beer (with and without alcohol) on cardiovascular health in postmenopausal women. A total of 34 participants were grouped into three study arms: 16 were administered alcoholic beer, 6 consumed non-alcoholic beer, and 12 were in the control group. Changes in glucose metabolism, lipid profile, liver enzymes, anthropometric measurements, body composition, and blood pressure variables were monitored. Data on medical history, diet, and exercise were collected, and gustatory capacities were determined.

RESULTS

Moderate consumption of beer, both alcoholic and non-alcoholic, seemed to have positive effects on biochemical indicators of cardiovascular health in postmenopausal women, with 660 mL day-1 of non-alcoholic beer reducing low-density lipoprotein cholesterol blood levels, and 330 mL day-1 of alcoholic beer increasing high-density lipoprotein cholesterol. The evolution of changes in android and gynoid fat percentage and their ratio differed significantly between study groups, which was attributable to either the interventions or the disparity between groups regarding the time elapsed since menopause onset. Iso-α-acids recognition threshold could be involved in intervention group election, whereas the sensory phenotypes studied were not associated with alcohol drinking frequency.

CONCLUSIONS

Moderate beer consumption was found to improve the lipid profile of postmenopausal women, although their effects in preventing cardiometabolic alterations deserve further research (trial registration number: ISRCTN13825020; https://doi.org/10.1186/ISRCTN13825020). © 2023 The Authors.

Susceptibility to hypertension based on MTHFR rs1801133 single nucleotide polymorphism and MTHFR promoter methylation

Background

The aetio-pathologenesis of hypertension is multifactorial, encompassing genetic, epigenetic, and environmental factors. The combined effect of genetic and epigenetic changes on hypertension is not known. We evaluated the independent and interactive association of MTHFR rs1801133 single nucleotide polymorphism (SNP) and MTHFR promoter methylation with hypertension among Taiwanese adults.

Methods

We retrieved data including, MTHFR promoter methylation, MTHFR rs1801133 genotypes (CC, CT, and TT), basic demography, personal lifestyle habits, and disease history of 1,238 individuals from the Taiwan Biobank (TWB).

Results

The distributions of hypertension and MTHFR promoter methylation quartiles (β < 0.1338, 0.1338 ≤ β < 0.1385, 0.1385 ≤ β < 0.1423, and β ≥ 0.1423 corresponding to

Conclusion

Independently, rs1801133 TT was associated with a higher risk of hypertension, but methylation was not. Based on genotypes, lower methylation was dose-dependently associated with a higher risk of hypertension in individuals with the CC genotype. Our findings suggest that MTHFR rs1801133 and MTHFR promoter methylation could jointly influence hypertension susceptibility.

Alcohol Intake and Blood Pressure Levels: A Dose-Response Meta-Analysis of Nonexperimental Cohort Studies

BACKGROUND

Alcohol consumption may increase blood pressure but the details of the relationship are incomplete, particularly for the association at low levels of alcohol consumption, and no meta-analyses are available for nonexperimental cohort studies.

METHODS

We performed a systematic search of longitudinal studies in healthy adults that reported on the association between alcohol intake and blood pressure. Our end points were the mean differences over time of systolic (SBP) and diastolic blood pressure (DBP), plotted according to baseline alcohol intake, by using a dose-response 1-stage meta-analytic methodology.

RESULTS

Seven studies, with 19 548 participants and a median follow-up of 5.3 years (range, 4-12 years), were included in the analysis. We observed a substantially linear positive association between baseline alcohol intake and changes over time in SBP and DBP, with no suggestion of an exposure-effect threshold. Overall, average SBP was 1.25 and 4.90 mm Hg higher for 12 or 48 grams of daily alcohol consumption, compared with no consumption. The corresponding differences for DBP were 1.14 and 3.10 mm Hg. Subgroup analyses by sex showed an almost linear association between baseline alcohol intake and SBP changes in both men and women, and for DBP in men while in women we identified an inverted U-shaped association. Alcohol consumption was positively associated with blood pressure changes in both Asians and North Americans, apart from DBP in the latter group.

CONCLUSIONS

Our results suggest the association between alcohol consumption and SBP is direct and linear with no evidence of a threshold for the association, while for DBP the association is modified by sex and geographic location.

Reactive Oxygen Species Are Central Mediators of Vascular Dysfunction and Hypertension Induced by Ethanol Consumption

Consumption of high amounts of ethanol is a risk factor for development of cardiovascular diseases such as arterial hypertension. The hypertensive state induced by ethanol is a complex multi-factorial event, and oxidative stress is a pathophysiological hallmark of vascular dysfunction associated with ethanol consumption. Increasing levels of reactive oxygen species (ROS) in the vasculature trigger important processes underlying vascular injury, including accumulation of intracellular Ca2+ ions, reduced bioavailability of nitric oxide (NO), activation of mitogen-activated protein kinases (MAPKs), endothelial dysfunction, and loss of the anticontractile effect of perivascular adipose tissue (PVAT). The enzyme nicotinamide adenine dinucleotide phosphate (NADPH) oxidase plays a central role in vascular ROS generation in response to ethanol. Activation of the renin-angiotensin-aldosterone system (RAAS) is an upstream mechanism which contributes to NADPH oxidase stimulation, overproduction of ROS, and vascular dysfunction. This review discusses the mechanisms of vascular dysfunction induced by ethanol, detailing the contribution of ROS to these processes. Data examining the association between neuroendocrine changes and vascular oxidative stress induced by ethanol are also reviewed and discussed. These issues are of paramount interest to public health as ethanol contributes to blood pressure elevation in the general population, and it is linked to cardiovascular conditions and diseases.

The Relationship Between Drinking Patterns and Chronic Health Conditions: New Evidence From Two U.S. National Alcohol Surveys

OBJECTIVE

The association of many chronic disease conditions with alcohol consumption is well established, and research on drinking patterns following diagnosis suggests that those with a chronic condition drink less than their healthy counterparts. However, these studies have not controlled for confounding influences on this relationship. This article reports current drinking patterns of those with one of four chronic disease conditions (hypertension, diabetes, heart disease, cancer) compared to those without, controlling for covariates.

METHOD

Data were analyzed from a merged sample of the two National Alcohol Surveys of the U.S. adult population (2014-2015 and 2019-2020; n = 9,597). Those reporting any one of the four disease conditions were matched to healthy control respondents on demographic characteristics and history of drinking using propensity score weighting (PSW).

RESULTS

Those with hypertension and heart disease appeared to drink less than controls during the last year, but after models were adjusted for covariates or PSW, no significant differences were found. For diabetes, only the PSW models showed no significant difference in drinking from controls, whereas both unadjusted and adjusted models for cancer showed no differences from controls.

CONCLUSIONS

Controlling for covariates and PSW appeared to make cases and their healthy controls more similar in past-year drinking patterns. Observed similarity in drinking patterns of those with and without a chronic disease may serve as an impetus for a greater focus on screening and identification of those with chronic conditions who would benefit from focused harm-reduction messages and implementation of effective alcohol interventions.

Dietary factors and hypertension risk in West Africa: a systematic review and meta-analysis of observational studies

BACKGROUND

Contrary to North America and Europe, the prevalence of hypertension is rising in West Africa. Although diet is implicated as a contributor to this trend, nutritional guidelines in West Africa are not tailored to address this concern. This study aimed to address this limitation by investigating dietary factors common to West Africa and evaluating their association with hypertension.

METHODS

PubMed, Scopus, Web of Science, and Medline were searched to identify studies that investigated diet and hypertension in West African adults. All meta-analyses used a generic inverse-variance random effects model, with subgroup analyses by age, BMI, and study location, and were performed in R.

RESULTS

Three thousand, two hundred ninety-eight studies were identified, of which 31 ( n  = 48 809 participants) satisfied inclusion criteria - all cross-sectional. Meta-analyses of the association between dietary factors and hypertension included dietary fat [odds ratio (OR) = 1.76; 95% confidence interval (95% CI) 1.44-2.14; P  < 0.0001], red meat (OR = 1.51; 95% CI: 1.04-2.18; P  = 0.03), junk-food (OR = 1.41; 95% CI: 1.19-1.67; P  < 0.0001), dietary salt (OR = 1.25; 95% CI: 1.12-1.40; P  < 0.0001), alcohol (OR = 1.17; 95% CI: 1.03-1.32; P  = 0.013), and 'fruits and vegetables' (OR = 0.80; 95% CI: 0.24-1.17; P  < 0.0001). Subgroup analyses suggested that 'fruit and vegetable' consumption is less protective in the elderly.

CONCLUSION

High consumption of dietary salt, red meat, dietary fat, junk food, and alcohol are associated with increased odds of hypertension, whereas high fruit and vegetable appear protective. This region-specific evidence will support the development of nutritional assessment tools for clinicians, patients, and researchers aiming to reduce hypertension in West Africa.

Associations between smoking and alcohol consumption with blood pressure in a middle-aged population

INTRODUCTION

Inconsistent association between tobacco smoking, alcohol consumption and hypertension have been highlighted. The purpose of our study was to investigate the associations between smoking use and alcohol with systolic and diastolic blood pressure (SBP, DBP) and hypertension in a middle-aged population.

METHODS

Smoking status was based on smoking pack-years and cigarettes per day, and alcohol consumption was measured in units/day. Gender associations between smoking and alcohol consumption with BP and hypertension were estimated using multiple linear regressions. Synergistic effects between smoking and alcohol were investigating in both genders.

RESULTS

A total of 290913 individuals of the UK Biobank population were included (133950 men and 156963 women). Current smoking was significantly associated with lower SBP, DBP and lower hypertension prevalence, in both genders (p<0.001). However, cigarettes per day were associated with higher SBP in men current smokers [B=0.05 (0.02), p<0.001] with higher hypertension (p=0.001) but not with DBP (p=0.205). Similar results were observed in women current smokers [SBP: B=0.10 (0.02), p<0.001; DBP, p=0.217 and hypertension, p=0.019]. The number of smoking pack-years was only associated with higher levels in SBP in men (p=0.047) and in women (p<0.001). In both genders, alcohol consumption was associated with higher SBP, DBP and hypertension (p<0.001). Synergistic effects were observed for alcohol consumption on smoking pack-years and cigarettes per day with SBP and DBP.

CONCLUSIONS

Smoking and alcohol were associated with higher BP in current smokers with synergistic effects. The findings suggest the importance of considering smoking and alcohol consumption in BP control in addition to antihypertensive medication and public health practice.

Mineralocorticoid receptors contribute to ethanol-induced vascular hypercontractility through reactive oxygen species generation and up-regulation of cyclooxygenase 2

The effects on blood pressure produced byethanol consumption include both vasoconstriction and activation of the renin-angiotensin-aldosterone system (RAAS), although the detailed relationship between these processes is yet to be accomplished. Here, we sought to investigate the contribution of mineralocorticoid receptors (MR) to ethanol-induced hypertension and vascular hypercontractility. We analyzed blood pressure and vascular function of male Wistar Hannover rats treated with ethanol for five weeks. The contribution of the MR pathway to the cardiovascular effects of ethanol was evaluated with potassium canrenoate, a MR antagonist (MRA). Blockade of MR prevented ethanol-induced hypertension and hypercontractility of endothelium-intact and -denuded aortic rings. Ethanol up-regulated cyclooxygenase (COX)2 and augmented vascular levels of both reactive oxygen species (ROS) and thromboxane (TX)B₂, a stable metabolite of TXA₂. These responses were abrogated by MR blockade. Hyperreactivity to phenylephrine induced by ethanol consumption was reversed by tiron [a scavenger of superoxide (O₂∙^-)], SC236 (a selective COX2 inhibitor) or SQ29548 (an antagonist of TP receptors). Treatment with the antioxidant apocynin prevented the vascular hypercontractility, as well as the increases in COX2 expression and TXA₂ production induced by ethanol consumption. Our study has identified novel mechanisms through which ethanol consumption promotes its deleterious effects in the cardiovascular system. We provided evidence for a role of MR in the vascular hypercontractility and hypertension associated with ethanol consumption. The MR pathway triggers vascular hypercontractility through ROS generation, up-regulation of COX2 and overproduction of TXA₂, which will ultimately induce vascular contraction.

Consumption frequencies of beverages and the hypertension risk in adults: a cohort study in China

OBJECTIVE

To explore the associations between the consumption frequencies of alcohol, tea and sugar-sweetened beverages (SSBs) and the hypertension risk among Chinese adults.

DESIGN

A longitudinal study of the effect of beverage consumption on hypertension risk.

SETTING

Nine provinces in China, including Jiangsu, Hubei, Hunan, Guangxi, Guizhou, Liaoning, Heilongjiang, Shandong and Henan.

PARTICIPANTS

The longitudinal data of the China Health and Nutrition Survey from 2004 to 2015 were used. A total of 4427 participants from 9 provinces were included at baseline.

OUTCOME

First incidence of hypertension.

RESULTS

During a mean follow-up of 8.7 years, 1478 participants developed hypertension. Alcohol consumption more than twice a week in young men (HR 1.86, 95% CI 1.09 to 3.18) or middle-aged men (HR 1.37, 95% CI 1.01 to 1.87) was associated with a higher hypertension risk. Middle-aged women who consumed tea frequently (HR 0.71, 95% CI 0.52 to 0.97), or young women who consumed SSBs less than once a week (HR 0.31, 95% CI 0.14 to 0.67) had a lower risk of hypertension.

CONCLUSIONS

High-frequency alcohol consumption increased the risk of hypertension in men, and frequent tea consumption and low-frequency SSBs consumption were associated with lower risk of hypertension in women. Consumption frequency of beverages was also suggested to be considered in the prevention and control of hypertension.

A Dose-Dependent Association between Alcohol Consumption and Incidence of Proteinuria and Low Glomerular Filtration Rate: A Systematic Review and Meta-Analysis of Cohort Studies

Previous cohort studies have reported conflicting associations between alcohol consumption and chronic kidney disease, characterized by proteinuria and low glomerular filtration rate (GFR). This systematic review, which included 14,634,940 participants from 11 cohort studies, assessed a dose-dependent association of alcohol consumption and incidence of proteinuria and low estimated GFR (eGFR) of <60 mL/min/1.73 m2. Compared with non-drinkers, the incidence of proteinuria was lower in drinkers with alcohol consumption of ≤12.0 g/day (relative risk 0.87 [95% confidence interval 0.83, 0.92]), but higher in drinkers with alcohol consumption of 36.1–60.0 g/day (1.09 [1.03, 1.15]), suggesting a J-shaped association between alcohol consumption and the incidence of proteinuria. Incidence of low eGFR was lower in drinkers with alcohol consumption of ≤12.0 and 12.1–36.0 than in non-drinkers (≤12.0, 12.1–36.0, and 36.1–60.0 g/day: 0.93 [0.90, 0.95], 0.82 [0.78, 0.86], and 0.89 [0.77, 1.03], respectively), suggesting that drinkers were at lower risk of low eGFR. In conclusion, compared with non-drinkers, mild drinkers were at lower risk of proteinuria and low eGFR, whereas heavy drinkers had a higher risk of proteinuria but a lower risk of low eGFR. The clinical impact of high alcohol consumption should be assessed in well-designed studies.

Alcohol Intake and Arterial Hypertension: Retelling of a Multifaceted Story

Alcoholic beverages are common components of diets worldwide and understanding their effects on humans' health is crucial. Because hypertension is the leading risk factor for cardiovascular diseases and all-cause mortality, the relationship of alcohol consumption with blood pressure (BP) has been the subject of extensive investigation. For the purpose of this review, we searched the terms "alcohol", "ethanol", and "arterial hypertension" on Pubmed MeSH and selected the most relevant studies. Short-term studies showed a biphasic BP response after ingestion of high doses of alcohol, and sustained alcohol consumption above 30 g/day, significantly, and dose-dependently, increased the risk for hypertension. These untoward effects of alcoholic beverages on BP can be mediated by a multiplicity of neurohormonal mechanisms. In addition to the effects on BP, excess alcohol intake might contribute to cardiac and renal hypertensive organ damage, although some studies suggest possible benefits of moderate alcohol consumption on additional cardiovascular risk factors, such as diabetes and lipoprotein(a). Some intervention studies and cumulative analyses support the evidence of a benefit of the reduction/withdrawal of alcohol consumption on BP and cardiovascular outcomes. This is why guidelines of scientific societies recommend avoidance or limitation of alcohol intake below one unit/day for women and two units/day for men. This narrative article overviews all these topics, providing an update of the current knowledge on the relationship between alcohol and BP.

The Alcohol Use Disorders Identification Test and Mortality 20 Years later

The objective was to test whether Alcohol Use Disorders Identification Test (AUDIT) results may predict mortality after 20 years. An observational study was conducted. It included an interview of a general population sample aged 18 to 64 in northern Germany in the years 1996 − 1997 (baseline) and a mortality-follow-up in the years 2017 − 2018. Study participants were 3581 persons who had consumed alcohol during the last 12 months prior to the baseline assessment. It included the AUDIT which was filled in by study participants. At follow-up, death cases were ascertained including the date of death. Official records and death certificates from local health authorities were used. Cox proportional hazards regression revealed that the AUDIT predicted time to death. The hazard ratio was 1.70 (95% confidence interval: 1.43 − 2.02) with the lowest AUDIT zone of values as the reference group. Competing risks regression analysis for diagnosis-specific mortality data revealed that the AUDIT predicted cardiovascular mortality (subhazard ratio, 1.84; 95% confidence interval, 1.49 − 2.27). It is concluded that the alcohol screening predicted total and cardiovascular mortality in this adult general population sample.

Association of alcohol types, coffee and tea intake with mortality: prospective cohort study of UK Biobank participants

The present study examines how alcohol intake from wine and non-wine alcoholic beverages (non-wine) in g/d, as well as cups of coffee and tea included as continuous covariates and mutually adjusted are associated with all-cause, cancer, non-cancer and CVD mortality. Consumption was assessed in 354 386 participants of the UK Biobank cohort who drank alcohol at least occasionally and survived at least 2 years after baseline with 20 201 deaths occurring over 4·2 million person-years. Hazard ratios (HR) for mortality were assessed with Cox proportional hazard regression models and beverage intake fitted as penalised cubic splines. A significant U-shaped association was detected between wine consumption and all-cause, non-cancer and CVD mortality. Wine consumption with lowest risk of death (nadir) ranged from 19 to 23 g alcohol/d in all participants and both sexes separately. In contrast, non-wine intake was significantly and positively associated in a dose-dependent manner with all mortality types studied except for CVD in females and with the nadir between 0 and 12 g alcohol/d. In all participants, the nadir for all-cause mortality was 2 cups coffee/d with non-coffee drinkers showing a slightly increased risk of death. Tea consumption was significantly and negatively associated with all mortality types in both sexes. Taken together, light to moderate consumption of wine but not non-wine is associated with decreased all-cause and non-cancer mortality. A minor negative association of coffee consumption with mortality cannot be excluded whereas tea intake is associated with a consistently decreased risk of all mortality types studied.

Mediterranean Alcohol-Drinking Pattern and Arterial Hypertension in the "Seguimiento Universidad de Navarra" (SUN) Prospective Cohort Study

Alcohol drinking patterns may determine the risk of hypertension and may also modify the detrimental effect of high alcohol intake. We prospectively evaluated the effect of the Mediterranean alcohol-drinking pattern and its interaction with the amount of alcohol consumed on the incidence of arterial hypertension. In the “Seguimiento Universidad de Navarra” (SUN) cohort, we followed-up 13,805 participants, all of them initially free of hypertension, during a maximum period of 16 years. Information about diet, chronic diseases, lifestyle and newly diagnosed hypertension was collected using validated questionnaires. We used a 7-item score (0 to 9 points) that jointly considered moderate alcohol consumption, distributed over the week, with meals, and a preference for red wine and avoidance of binge-drinking. During 142,404 person-years of follow-up, 1443 incident cases of hypertension were identified. Low adherence (score < 2) to the Mediterranean alcohol-drinking pattern was significantly associated with a higher incidence of hypertension (multivariable-adjusted hazard ratio 1.81, 95% confidence interval 1.09−2.99) as compared to the high-adherence (score > 7) category. Among alcohol consumers, a high adherence to the MADP is associated with a lower incidence of hypertension. Compared with abstinence, a high adherence did not seem to differ regarding its effect on hypertension risk.

Sociodemographic and behavioral factors associated with controlled hypertension after 9 years of observation of a PURE Poland cohort study

Introduction

Despite some improvement in awareness and treatment of hypertension, blood pressure control is still below expectations in Poland. The aim of the study was to analyze the secular trend of hypertension prevalence in the PURE Poland cohort study over 9 years of observation and to analyze factors associated with controlled HT.

Methods

The study group consisted of 1,598 participants enrolled in a Prospective Urban and Rural Epidemiological Study (PURE), who participated both in baseline (2007-2010) and 9-year follow-up (2016-2019). Hypertension was ascertained on the basis of (1) self-reported hypertension previously diagnosed by the physician, (2) self-reported anti-hypertensive medication, and/or (3) an average of two blood pressure measurements ≥140 mmHg systolic BP and/or ≥90 mmHg diastolic BP.

Results

The prevalence of hypertension increased from 69.4% at baseline to 85.9% at 9-year follow-up. The chance of HT was 8.6-fold higher in the oldest vs. the youngest age group [OR 8.55; CI 4.47-16.1]. Male sex increased the chance for hypertension over 3-fold [OR 3.23; CI 2.26-4.73]. Obesity, according to BMI, increased the chance of HT 8-fold [OR 8.01; CI 5.20-12.8] in comparison with normal body weight. Male sex decreased the chance of controlled HT after 9 years [OR 0.68; CI 0.50-0.92]. There was no statistically significant association between controlled HT and age or place of residence. Higher and secondary education increased the chance of controlled HT over 2-fold in comparison with primary education [OR 2.35; CI 1.27-4.34, OR 2.34; CI 1.33-4.11]. Obesity significantly decreased the chance of controlled HT after 9 years in comparison with normal body weight [OR 0.54; CI 0.35-0.83].

Conclusion

Factors significantly increasing the chance for controlled hypertension after 9 years were female sex, secondary and tertiary education, normal body weight, and avoiding alcohol drinking. Changes in lifestyle, with special emphasis on maintaining normal body weight, should be the basis of prevention and control of HT.

Association of short-term changes in drinking after onset of a serious health condition and long-term heavy drinking

BACKGROUND

Literature on changes in drinking following diagnosis of chronic health conditions is limited, especially differential response to specific conditions or across demographic subgroups. Methods Data were analyzed from the 2020 National Alcohol Survey of the U.S. adult population (n = 9968). Predictors of change in drinking following first diagnosis of hypertension, heart disease, diabetes, and cancer, and how the short-term post-disease change in drinking was associated with a change in long-term heavy (5 +) drinking from the decade before diagnosis to the decade following diagnosis were analyzed. Results The majority of respondents reported no change in drinking after diagnosis. Men were more likely than women to reduce drinking after hypertension (OR=1.47) but less likely to quit after heart disease (OR=0.46). Black and Hispanic/Latinx drinkers were more likely than white or other drinkers to reduce (OR=2.68, 2.35, respectively) or quit (OR=2.69, 2.34) after hypertension, and more likely to quit after diabetes (OR=3.44, 2.74) and cancer (OR=5.00, 5.27). Black drinkers were more likely to quit after heart disease (OR=3.26). Heavier drinkers were more likely to reduce or quit drinking than lighter drinkers. For all disease types, those who quit drinking after disease onset were less likely to report heavy drinking in the following decade. Conclusions Just cutting down had little effect on subsequent long-term heavy drinking compared to quitting. These data are important for informing efforts aimed at harm reduction in patients diagnosed with a chronic health condition and suggest specific demographic subgroups.

Implementation of non-pharmacological interventions for the treatment of hypertension in primary care: a narrative review of effectiveness, cost-effectiveness, barriers, and facilitators

BACKGROUND

The current guidelines for the prevention, detection, evaluation, and management of hypertension recommend six types of non-pharmacological interventions: alcohol reduction, salt intake reduction, increased potassium intake, physical activity, weight loss, and heart-healthy diets. However, the non-pharmacological interventions are still not widely used in primary care. In this paper, we, therefore, reviewed and summarised the evidence on the effectiveness, cost-effectiveness, barriers, and facilitators of non-pharmacological interventions for the treatment of hypertension in primary care.

METHODS

A thorough literature search was conducted in Embase, Google Scholar, and PubMed databases, to identify the most recent reviews or, in their absence, primary studies on alcohol reduction, salt intake reduction, potassium supplementation, physical activity, weight reduction, heart-healthy diets, and other non-pharmacological interventions for the treatment of hypertension in primary care.

RESULTS

Alcohol reduction is a non-pharmacological intervention for the treatment of hypertension in primary care with proven effectiveness, feasibility, and acceptability. Interventions for sodium intake reduction, physical activity, and weight reduction are effective but there is insufficient evidence regarding their feasibility and acceptability in primary care settings. Evidence on the effectiveness of potassium intake and heart-healthy diets is limited and inconsistent. There is a lack of evidence on the cost-effectiveness of non-pharmacological interventions in the treatment of hypertension. The most common barriers to deliver such interventions related to healthcare providers include a lack of time, knowledge, self-confidence, resources, clear guidelines, and financial incentives. The most common barriers related to patients include a lack of motivation and educational resources. Less evidence is available on facilitators of implementing non-pharmacological interventions in primary care. Besides, facilitators differed by different types of interventions.

CONCLUSIONS

Available evidence suggests that more pragmatic, clinically feasible, and logistically simple interventions are required for sodium intake reduction, physical activity, and weight reduction in primary care settings. Future studies should provide further evidence on the effectiveness of weight control, potassium intake, and heart-healthy diets. More research is also needed on cost-effectiveness and facilitators of all types of effective non-pharmacological interventions for the treatment of hypertension in primary care.

Prevalences of cardiometabolic risk and lifestyle factors in young parents: evidence from a German birth cohort study

Background

Studies show that parents significantly impact their children’s health through their cardiometabolic risk profile and health behavior. There is only little information about the prevalence of cardiometabolic risk factors and lifestyle factors among new parents yet. The aims of this study are therefore to evaluate the prevalences of cardiometabolic risk factors in parents of infants in Germany and to examine their lifestyle and health behavior.

Methods

In the KUNO-Kids health study, an ongoing birth cohort, parents (n = 930 mothers and 769 fathers) were asked about cardiometabolic risk factors (obesity/hypertension/type 2 diabetes mellitus) and lifestyle factors (dietary/sports/smoking habits/alcohol consumption) during the first year after the birth of their children via questionnaires. Chi-square as well as fisher exact tests were conducted to analyse associations between lifestyle factors and cardiometabolic risk factors.

Results

34.2% of mothers and 58.5% of fathers were overweight or obese. In 11.8% of the families, at least one parent suffered from hypertension, in 2.4% from type 2 diabetes mellitus. One year after delivery, 8.5% of mothers were smoking, 6.9% showed a risky alcohol consumption (> 10 g/d). 16.0% of fathers were smoking 4 weeks after childbirth, 10.7% showed risky alcohol consumption (> 20 g/d). 21.6% of mothers carried out sports activity for more than 2 h a week then. Parental hypertension was linked to a higher prevalence of risky alcohol consumption, obesity to a lower prevalence of daily fruits consumption.

Conclusions

Cardiometabolic risk factors were widespread among new parents with obesity and overweight having the highest prevalences. A considerable number of parents also practiced an unhealthy lifestyle showing that there is potential for improvement to promote the healthy development of their children.

Trends in concurrent tobacco use and heavy drinking among individuals 15 years and older in Mongolia

The study aimed to evaluate trends in the prevalence and correlates of current tobacco use only (= CT), current heavy drinking only (= CHD), and current tobacco use and current heavy drinking (= CTHD) in people 15 years and older from 2009 to 2019 in Mongolia. Cross-sectional data were analyzed from 5,438 individuals (15-64 years) of the Mongolia STEPS 2009 survey, 6,013 (15-69 years) of the Mongolia STEPS 2013 survey, and 6,654 persons (15-69 years) of the Mongolia STEPS 2019 survey and responded to questions about substance use, other health risk behaviours and physical measurements. Trend analysis shows that the prevalence of CT increased from 14.4% in 2009 to 15.3% in 2019, and the prevalence of CHD significantly decreased from 13.3% in 2009 to 10.3% in 2019, and the prevalence of CTHD significantly decreased from 14.2% in 2009 to 9.4% in 2019. Middle and older age, male sex (13 times higher for CT, 3.4 times higher for CHD, and 28 times higher for CTHD) and high physical activity significantly increased the odds of CT, CHD and CTHD. Higher education decreased the odds of CT but increased the odds of CHD. Urban residence was positively associated with CT, and among women with CTHD. Underweight decreased the odds of CT, CHD, and CTHD, and obesity decreased the odds of CT and CTHD and increased the odds of CHD. Hypertension was positively associated with CHD and CTHD, while sedentary behaviour was positively associated with CT and CTHD. Being Khalkh by ethnicity increased the odds of CT and inadequate fruit and vegetable intake increased the odds of CHD. More than one in six persons 15 years and older engaged in CT and more than one in ten engaged in CHD and CTHD. Several sociodemographic factors, such as male sex and middle and/or older age, and health variables, such as obesity and hypertension for CHD, were identified associated with CT, CHD, and CTHD that can help in guiding public interventions.

Addressing alcohol use among blood pressure patients in Thai primary care: Lessons from a survey-based stakeholder consultation

Alcohol use is a major risk factor for noncommunicable diseases in Thailand, and one of its pathways is high blood pressure. Given that brief intervention can effectively reduce hazardous alcohol consumption, this study aimed to investigate how hypertensive patients with concomitant alcohol use are identified and treated in Thai primary care settings and what this may mean for screening and lifestyle intervention strategies. In a cross-sectional, mixed-method design, we surveyed 91 participants from three different groups of Thai stakeholders: policy- and decisionmakers; healthcare practitioners; and patients diagnosed with hypertension. Data was collected between December 2020 and May 2021. Responses were analyzed descriptively and using open coding tools to identify current practices, barriers, facilitators, and implications for interventions. All stakeholder groups regarded alcohol use as an important driver of hypertension. While lifestyle interventions among hypertensive patients were perceived as beneficial, current lifestyle support was limited. Barriers included limited resources in primary healthcare facilities, lack of continuous monitoring or follow-up, missing tools or procedures for risk assessment and lifestyle intervention, and stigmatization of alcohol use. Our results suggest that although screening for lifestyle risk factors (including alcohol use) and lifestyle interventions are not yet sufficiently established, a wide range of stakeholders still recognize the potential of interventions targeted at hazardous alcohol use among hypertensive patients. Future interventions may establish standardized assessment tools, be tailored to high-risk groups, and include electronic or remote elements.

Reproductive lifespan in association with risk of hypertension among Chinese postmenopausal women: Results from a large representative nationwide population

Background

The association between reproductive lifespan and risk of hypertension among postmenopausal women is unclear.

Methods

A total of 94,141 postmenopausal women with a mean age of 64.8 years from the China Hypertension Survey were enrolled at baseline from 2012 to 2015. A standardized questionnaire was used to collect relevant information by well-trained interviewers. Blood pressure and physical examination of the participants were performed by trained medical staff. Logistic regression was used to estimate the odds ratios for hypertension by years of reproductive lifespan.

Results

The average years of reproductive lifespan in Chinese women was 34.0 years. Women who were longer in reproductive lifespan were more likely to have older age at recruitment, higher body mass index, larger waist circumference, lower mean systolic blood pressure, and higher mean diastolic blood pressure (p &lt; 0.05). After adjustments, odds ratios (95% confidence interval) for hypertension were 1.035 (0.988–1.085), 1.007 (0.966–1.048), 1.000 (reference), 0.932 (0.899–0.967), and 0.953 (0.909–0.997) for those with reproductive lifespan at ≤ 28, 29–31, 32–34 (reference), 35–37, and ≥ 38 years, respectively, with a significantly inverse association was seen in those with reproductive lifespan at 35–37 and ≥ 38 years. The overall risk of hypertension declined with the increase in reproductive lifespan, and the risk of hypertension was reduced by 1.1% for every 1-year increase in the reproductive lifespan (odds ratio, 0.989; 95% confidence interval, 0985–0.994) per year. The negative association between reproductive lifespan and hypertension was evident among age at recruitment groups, body mass index categories, and education levels, with the strongest association among women aged ≥ 70 years. Positive associations between reproductive lifespan and risk of hypertension were evident among women aged &lt; 60 years, and this association was stronger among current alcohol drinkers.

Conclusion

Based on the large nationally representative sample, Chinese postmenopausal women with a shorter reproductive lifespan have a higher risk of hypertension.

Urinary Sodium Excretion Enhances the Effect of Alcohol on Blood Pressure

Alcohol consumption is linked to urinary sodium excretion and both of these traits are linked to hypertension and cardiovascular diseases (CVDs). The interplay between alcohol consumption and sodium on hypertension, and cardiovascular diseases (CVDs) is not well-described. Here, we used genetically predicted alcohol consumption and explored the relationships between alcohol consumption, urinary sodium, hypertension, and CVDs.

METHODS

We performed a comparative analysis among 295,189 participants from the prospective cohort of the UK Biobank (baseline data collected between 2006 and 2010). We created a genetic risk score (GRS) using 105 published genetic variants in Europeans that were associated with alcohol consumption. We explored the relationships between GRS, alcohol consumption, urinary sodium, blood pressure traits, and incident CVD. We used linear and logistic regression and Cox proportional hazards (PH) models and Mendelian randomization in our analysis.

RESULTS

The median follow-up time for composite CVD and stroke were 6.1 years and 7.1 years respectively. Our analyses showed that high alcohol consumption is linked to low urinary sodium excretion. Our results showed that high alcohol GRS was associated with high blood pressure and higher risk of stroke and supported an interaction effect between alcohol GRS and urinary sodium on stage 2 hypertension (P_interaction = 0.03) and CVD (P_interaction = 0.03), i.e., in the presence of high urinary sodium excretion, the effect of alcohol GRS on blood pressure may be enhanced.

CONCLUSIONS

Our results show that urinary sodium excretion may offset the risk posed by genetic risk of alcohol consumption.

Diabetes, Hypertension, and the Mediating Role of Lifestyle: A Cross-Sectional Analysis in a Large Cohort of Adults

INTRODUCTION

Whether diabetes is associated with hypertension risk remains controversial, potentially owing to the confounding effect of lifestyle. This study aims to analyze the association between diabetes and hypertension in adults and the mediating impacts of lifestyle.

METHODS

A cohort of Spanish workers (aged 18-64 years) insured by an occupational risk prevention company participated in this nationwide cross-sectional study between 2012 and 2016 (data analysis was performed in 2021). Participants' lifestyle‒related factors-BMI, sleeping hours, alcohol, smoking, and physical activity-were assessed, and the prevalence of hypertension and diabetes was registered.

RESULTS

A total of 451,157 participants (33.1% women, aged 44.5 [SD=9.2] years, 3.2% with diabetes, and 29.3% with hypertension) with complete data for all variables were assessed. Having diabetes was associated with a higher prevalence of hypertension even after adjusting for all lifestyle-related factors (OR=1.44, 95% CI=1.43, 1.48), and people with diabetes and hypertension had a higher prevalence of mild kidney function impairment than people with diabetes alone (OR=1.06, 95% CI=1.01, 1.13). However, people with diabetes and an optimal lifestyle-normal weight and sleeping hours, absent-to-little alcohol drinking, nonsmoking, and regular physical activity-presented a prevalence of hypertension comparable with that of those without diabetes (OR=1.00, 95% CI=0.71, 1.32). In separate analyses among people with diabetes, an optimal lifestyle was associated with a lower prevalence of hypertension than the worse-opposite-lifestyle (OR=0.29, 95% CI=0.18, 0.53). The lifestyle-related factors showing the strongest inverse association with adjusted risk of hypertension were normal weight (OR=0.49, 95% CI=0.42, 0.53 versus overweight/obesity) and regular physical activity (OR=0.79, 95% CI=0.74, 0.82 versus inactivity).

CONCLUSIONS

Diabetes is positively and largely independently associated with hypertension risk. Yet, a healthy lifestyle can attenuate this association.

The Cardiometabolic Health of African Immigrants in High-Income Countries: A Systematic Review

In recent decades, the number of African immigrants in high-income countries (HICs) has increased significantly. However, the cardiometabolic health of this population remains poorly examined. Thus, we conducted a systematic review to examine the prevalence of cardiometabolic risk factors among sub-Saharan African immigrants residing in HICs. Studies were identified through searches in electronic databases including PubMed, Embase, CINAHL, Cochrane, Scopus, and Web of Science up to July 2021. Data on the prevalence of cardiometabolic risk factors were extracted and synthesized in a narrative format, and a meta-analysis of pooled proportions was also conducted. Of 8655 unique records, 35 articles that reported data on the specific African countries of origin of African immigrants were included in the review. We observed heterogeneity in the burden of cardiometabolic risk factors by African country of origin and HIC. The most prevalent risk factors were hypertension (27%, range: 6-55%), overweight/obesity (59%, range: 13-91%), and dyslipidemia (29%, range: 11-77.2%). The pooled prevalence of diabetes was 11% (range: 5-17%), and 7% (range: 0.7-14.8%) for smoking. Few studies examined kidney disease, hyperlipidemia, and diagnosed cardiometabolic disease. Policy changes and effective interventions are needed to improve the cardiometabolic health of African immigrants, improve care access and utilization, and advance health equity.

Prevalence of hypertension among individuals with diabetes and its determinants: Evidences from the National Family Health Survey 2015-16, India

BACKGROUND

The incidence of Diabetes mellitus (DM) has escalated in recent decades, and the risk of diabetes-related mortality has increased dramatically due to the co-existence of hypertension (HTN). DM and HTN, having similar aetiology and disease mechanism, are influenced by lifestyle factors and greatly contribute to critical health complications.

AIM

The present study attempted to explore the co-existence of DM-HTN and the potential determinants considering rapid upsurge of both the diseases.

SUBJECTS AND METHODS

National Family Health Survey data were used, which included 7092 adult diabetic individuals, to find out the prevalence rate of HTN in diabetic persons in India. Appropriate statistical analyses were performed to accomplish the study objectives.

RESULTS

Prevalence rate of HTN in diabetic individuals was approximately 37%. Higher BMI was associated with DM-HTN co-existence. In males, increased age, higher BMI, alcohol consumption, poorest wealth index, and non-smoking (tobacco) were the significant determinants of the co-existence of DM-HTN, while in females, they were increased age, higher BMI, and geographical region.

CONCLUSION

This study unveiled the significance of healthy lifestyle maintenance and equitable health care services to prevent HTN among the diabetics, along with promotion of the awareness and management of DM and HTN through appropriate pharmacological treatments.

Alcohol Consumption: Medical Implications, the Liver and Beyond

Alcohol consumption represents a major factor of morbidity and mortality, with a wide range of adverse medical implications that practically affect every organ system. It is the fifth major cause of deaths in men and women and causes up to 139 million disability-adjusted life years. Solid evidence places the risk as undoubtedly correlated to the length of time and amount of alcohol consumption. While alcohol-related liver disease represents one of the most studied and well-known consequences of alcohol use, the term itself embodies a wide spectrum of progressive disease stages that are responsible for almost half of the liver-related mortality worldwide. We discuss the staged alcohol-related fatty liver, alcohol-related steatohepatitis and, finally, fibrosis and cirrhosis, which ultimately may end up in a hepatocellular carcinoma. Other comorbidities such as acute and chronic pancreatitis; central nervous system; cardiovascular, respiratory and endocrine system; renal disease; urological pathologies; type 2 diabetes mellitus and even infectious diseases are reviewed in their relation to alcohol consumption. This article reviews the impact of alcohol use on different systems and organs, summarizing available evidence regarding its medical implications. It examines current basic and clinical data regarding mechanisms to highlight factors and processes that may be targetable to improve patient outcomes. Although alcohol use is a part of many cultural and social practices, as healthcare providers we must identify populations at high risk of alcohol abuse, educate patients about the potential alcohol-related harm and provide appropriate treatment.

Association between Drinking Patterns and Incident Hypertension in Southwest China

Based on a prospective cohort study of adults from southwest China with heterogeneity in their demographical characteristics and lifestyles, we aimed to explore the association between drinking patterns and incident hypertension under the interaction of these confounding factors. The Cox proportional hazard model was used to estimate the hazard ratios (HR) and 95% confidence intervals (95% CI). Subgroup analysis was performed according to sex, ethnicity, area, occupation, smoking, and exercise to compare the differences in the association between drinking patterns and the incidence of hypertension. Blood pressure was higher in participants with a high drinking frequency than those with a low drinking frequency (p < 0.001). We found that total drinking frequency, liquor drinking frequency, rice wine drinking frequency, and alcohol consumption were significantly associated with an increased risk of hypertension. Compared with the non-drinking group, a heavy drinking pattern was positively correlated with hypertension. Drinking can increase the risk of hypertension, especially heavy drinking patterns, with a high frequency of alcohol intake and high alcohol consumption. From the analysis results of the longitudinal data, drinking alcohol is still an important risk factor for hypertension among Chinese subjects, especially for men, the rural population, the employed, the Han nationality, smokers, and certain exercise populations.

Alcohol Consumption and the Risk of Incident Atrial Fibrillation: A Meta-Analysis

Alcohol consumption is a known, modifiable risk factor for incident atrial fibrillation (AF). However, it remains unclear whether the protective effect of moderate alcohol consumption-that has been reported for various cardiovascular diseases also applies to the risk for new-onset AF. The purpose of this meta-analysis was to evaluate the role of different drinking patterns (low: <14 grams/week; moderate: <168 grams/week; and heavy: >168 grams/week) on the risk for incident AF. Major electronic databases were searched for observational cohorts examining the role of different drinking behaviors on the risk for incident AF. We analyzed 16 studies (13,044,007 patients). Incident AF rate was 2.3%. Moderate alcohol consumption significantly reduced the risk for new-onset AF when compared to both abstainers (logOR: −0.20; 95%CI: −0.28–−0.12; I2: 96.71%) and heavy drinkers (logOR: −0.28; 95%CI: −0.37–−0.18; I2: 95.18%). Heavy-drinking pattern compared to low also increased the risk for incident AF (logOR: 0.14; 95%CI: 0.01–0.2; I2: 98.13%). Substantial heterogeneity was noted, with more homogeneous results documented in cohorts with follow-up shorter than five years. Our findings suggest a J-shaped relationship between alcohol consumption and incident AF. Up to 14 drinks per week seem to decrease the risk for developing AF. Because of the substantial heterogeneity observed, no robust conclusion can be drawn. In any case, our results suggest that the association between alcohol consumption and incident AF is far from being a straightforward dose-response effect.

Association between Exercise and Blood Pressure in Hypertensive Residents: A Meta-Analysis

BACKGROUND

Exercise is recommended as an effective lifestyle behaviour for adults to prevent and treat hypertension. In this study, a randomized-effect meta-analysis was used to analyse the influence of exercise interventions on blood pressure in patients with hypertension.

METHODS

Candidate papers were retrieved from PubMed, Web of Science, Embase, and Cochrane Library electronic databases, and 46 studies were finally included and analysed.

RESULTS

It was shown that preplanned walking (systolic blood pressure (SBP): WMD (weighted mean difference) = -5.94, 95% CI: -8.57, -3.30; diastolic blood pressure (DBP): WMD = -2.66, 95% CI: -3.66, -1.67), yoga (SBP: WMD = -5.09, 95% CI: -9.28, -0.89; DBP: WMD = -3.06, 95% CI: -5.16, -0.96), aquatic sports (SBP WMD = -7.53, 95% CI: -11.40, -3.65; DBP: WMD = -5.35, 95% CI: -9.00, -1.69), and football (SBP: WMD = -6.06, 95% CI: -9.30, -2.82; DBP: WMD = -5.55, 95% CI: -8.98, -2.13) had significant effects on blood pressure reduction. However, Tai Chi (SBP: WMD = -8.31, 95% CI: -20.39, 3.77; DBP: WMD = -3.05, 95% CI: -6.96, 0.87) and Qigong (SBP: WMD = -4.34, 95% CI: -13.5, 4.82; DBP: WMD = -3.44, 95% CI: -7.89, 1.01) did not significantly reduce blood pressure. The heterogeneity of the meta-analysis was high.

CONCLUSION

Walking, yoga, aquatic sports, and football were feasible and independent lifestyle interventions, and they were effective options for treating hypertension. More scientifically designed randomized controlled trials are needed in the future to further compare different forms of exercise for the treatment of hypertension.

Are there non-linear relationships between alcohol consumption and long-term health?: a systematic review of observational studies employing approaches to improve causal inference

Background

Research has long found ‘J-shaped’ relationships between alcohol consumption and certain health outcomes, indicating a protective effect of moderate consumption. However, methodological limitations in most studies hinder causal inference. This review aimed to identify all observational studies employing improved approaches to mitigate confounding in characterizing alcohol–long-term health relationships, and to qualitatively synthesize their findings.

Methods

Eligible studies met the above description, were longitudinal (with pre-defined exceptions), discretized alcohol consumption, and were conducted with human populations. MEDLINE, PsycINFO, Embase and SCOPUS were searched in May 2020, yielding 16 published manuscripts reporting on cancer, diabetes, dementia, mental health, cardiovascular health, mortality, HIV seroconversion, and musculoskeletal health. Risk of bias of cohort studies was evaluated using the Newcastle-Ottawa Scale, and a recently developed tool was used for Mendelian Randomization studies.

Results

A variety of functional forms were found, including reverse J/J-shaped relationships for prostate cancer and related mortality, dementia risk, mental health, and certain lipids. However, most outcomes were only evaluated by a single study, and few studies provided information on the role of alcohol consumption pattern.

Conclusions

More research employing enhanced causal inference methods is urgently required to accurately characterize alcohol–long-term health relationships. Those studies that have been conducted find a variety of linear and non-linear functional forms, with results tending to be discrepant even within specific health outcomes.

Association between alcohol and bone mineral density in a Mendelian randomization study: the Dong-gu study

INTRODUCTION

Many previous studies have reported a positive relationship between alcohol and bone mineral density (BMD). However, the causality between alcohol and BMD has not been fully evaluated.

MATERIALS AND METHODS

This study enrolled 8892 participants from the Dong-gu study. Mendelian randomization (MR) using two-stage least-squared regression was used to evaluate the association between the genetically predicted amount of alcohol consumption per day and BMD. The aldehyde dehydrogenase 2 (ALDH2) rs671 polymorphism was used as instrumental variables for alcohol consumption. Age, smoking history, and BMI were adjusted in the multivariate model.

RESULTS

Self-reported alcohol consumption was positively related to total hip and lumbar spine BMD in both sexes. In multivariate Mendelian randomization analysis, the genetically predicted amount of alcohol consumption was positively associated with both total hip and lumbar spine BMD in men. Total hip BMD and lumbar spine BMD increased by 0.004 g/cm² (95% confidence interval [CI] 0.002-0.007) and 0.007 g/cm² (95% CI 0.004-0.011) with doubling of alcohol consumption. However, in women, genetically predicted alcohol consumption was not significantly associated with BMD.

CONCLUSION

In our MR study, genetically predicted alcohol consumption was positively associated with BMD in men. This result suggests that the association between alcohol consumption and BMD is causal.

Estimating the burden of hypertension and its significant risk factors among male commercial drivers in sub-Saharan Africa: A systematic review and meta-analysis

OBJECTIVE

The study was designed to assess the burden and significant risk factors among male commercial drivers in sub-Saharan Africa (SSA).

DESIGN

Systematic review and meta-analysis.

DATA SOURCES

Medline via PubMed, Google Scholar, Cochrane databases and Africa Journal Online were searched from January 2010 to December 2020.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

The authors included observational studies reporting on the burden and/or risk factors for hypertension among commercial drivers in SSA. Male adult population ≥18 years working as a commercial driver in SSA as well articles published in English.

DATA EXTRACTION AND SYNTHESIS

Two independent coauthors used a prepared data extraction form to extract data from the eligible published papers and assessed the risk of bias. DerSimonian and Laird random effects model was used to pool the burden of hypertension and significant risk factors among male commercial drivers in SSA. The presence of heterogeneity among studies was quantified by estimating variance using both Cochrane's Q statistics and the I² statistics. A subgroup and sensitivity analyses were performed.

RESULTS

Overall, 14 articles met the inclusion criteria involving a total of 4285 male commercial drivers in SSA. The estimated pooled burden of hypertension among the male commercial drivers in SSA was 32% (95% CI 24% to 39%). The risk factors identified were age OR=1.10 (95% CI 1.06 to 1.15), overweight/obese OR=3.38 (95% CI 2.46 to 4.29), alcohol consumption OR=3.00 (95% CI 2.05 to 3.95) and duration of driving (≥5 years) OR=1.83 (95% CI 1.03 to 2.63). Funnel plot inspection and Egger's regression test of small effect (0.5838) showed no evidence of publication bias.

CONCLUSIONS

Our review showed that nearly one-third of male commercial drivers in SSA have hypertension. Reduction of modifiable risk factors such as overweight/obesity, alcohol consumption and long-term driving through multifaceted implementation strategies are recommended for prevention and control of hypertension among male commercial drivers in SSA.

Alcohol Consumption and Systemic Hypertension (from the Third National Health and Nutrition Examination Survey)

Epidemiological studies have established the association between excessive alcohol consumption and systemic hypertension (SH). However, there are conflicting reports of the association of low to moderate alcohol consumption with SH. The objective of the study was to examine the associations of alcohol consumption and blood pressure categories using the 2017 American College of Cardiology/American Heart Association high blood pressure guidelines. This analysis included 17,059 participants from the Third National Health and Nutrition Examination Survey. Alcohol consumption was ascertained by way of a questionnaire. Blood pressure (mm Hg) was measured during the in-home interview and the participant's visit to the mobile examination center. We used multivariable logistic regression models to examine cross-sectional associations of alcohol consumption and blood pressure categories based on new American College of Cardiology/American Heart Association High Blood Pressure guidelines. Models were adjusted for age, gender, income, and cardiovascular risk factors. Compared with never drinkers, moderate drinkers (7 to 13 drinks/week) had increased odds of prevalent stage 1 and stage 2 SH (odds ratio [95% confidence interval] 1.51 [1.22 to 1.87] and 1.55 [1.20 to 2.00]). Similarly, there were significantly higher odds of prevalent stage 1 and stage 2 SH among heavy drinkers (≥14 drinks/week) (odds ratio [95% confidence interval] 1.65 [1.33 to 2.05] and 2.46 [1.93 to 3.14]). We did not find any association between alcohol consumption and elevated blood pressure category. Response bias must be considered because alcohol consumption was self-reported. Our study indicates the need for further research to understand the potential mechanisms by which alcohol consumption increases the risk of SH. In conclusion, this analysis from a population-based survey showed an association between moderate and heavy alcohol consumption and a higher prevalence of SH.

Factors Associated With Hypertension Awareness, Treatment, and Control Among Adults in Kerala, India

Background: Hypertension, the most significant risk factor for cardiovascular disease, is an increasing contributor to global health burden, particularly in low- and middle-income countries (LMICs) such as India. While the rates of hypertension awareness, treatment, and control in India have been reported in several studies, the factors associated with these rates are less well-understood. Existing studies are predominantly cross-sectional, and the factors examined are limited. Understanding the predictors associated with these rates, using more rigorous study designs, is crucial for the development of strategies to improve hypertension management.

Aims: To examine a range of factors associated with hypertension awareness, treatment, and control using both cross-sectional and longitudinal analyses.

Methods: Data was derived from a population-based sample of 1,710 participants from Kerala, aged 30–60 years. We examined a comprehensive range of factors, including demographic, behavioral factors, anthropometric, clinical measures, psychosocial factors and healthcare utilization. Multilevel mixed effects logistic regression was used for both cross-sectional and longitudinal analyses (repeated measures for all variables across 2 years) to determine the factors associated with awareness, treatment, and control of hypertension.

Results: A total of 467 (27.3%) participants had hypertension at baseline. Among those, the rates of awareness, treatment, and control of hypertension were 54.4, 25.5, and 36.4%, respectively. Being male (OR 0.27, 95% CI 0.14–0.53) and consumption of alcohol (OR 0.49, 95% CI 0.31–0.80) were significant predictors of poorly controlled hypertension (longitudinal analysis). Depression (OR 2.04, 95% CI 1.15–3.61) and fair-to-poor self-perceived health status (OR 1.87, 95% CI 1.15–3.04) were associated with increased hypertension awareness, whereas anxiety (OR 1.97, 95% CI 1.04–3.71) was associated with increased hypertension treatment (cross-sectional analysis). Seeking outpatient service in the past 4 weeks was associated with higher awareness (OR 1.09, 95% CI 1.27–2.87), treatment (OR 1.73, 95% CI 1.20–2.50) and control (OR 1.96, 95% CI 1.37–2.80) (longitudinal analysis).

Conclusion: Our findings suggest the importance of considering psychosocial factors and better engagement with health services in hypertension management, as well as giving more attention to body fat control and largely male-related behaviors such as alcohol consumption, taking into account of some Indian specific attributes.

The longitudinal associations between trajectory of and quantity of alcohol consumption and subsequent changes in blood pressure levels among non-hypertensive adults

Given the dynamic characteristic of an individual's drinking behaviours, comprehensive consideration of alcohol consumption variation using repeated measures may improve insight into the nature of its association with blood pressure (BP) change. We examined the association between longitudinal alcohol consumption (trajectory and quantity) and changes in BP and pulse pressure (PP) among Korean aged ≥ 40 years living in rural areas. Totally, 1682 hypertension-free participants who completed all three health examinations (median, 5·3 years) were included. All three visits were used to determine the cumulative trajectory of and quantity of alcohol consumption and the latest two visits and the last visit were used for the recent trajectory and the most recent quantity of alcohol consumption, respectively. Changes in BP and PP from the baseline to the third visit were used as outcome. In men, ≥30 ml/d cumulative average alcohol consumption was associated with the greatest increase in systolic BP (SBP) in both baseline outcome-unadjusted (2·9 mmHg, P = 0·032) and -adjusted models (3·6 mmHg, P = 0·001), and the given association for the most recent alcohol consumption was observed in the baseline outcome-adjusted model (3·9 mmHg, P = 0·003). For PP, similar associations were observed only in the baseline outcome-adjusted model. No meaningful associations in diastolic BP in men and any BP or PP in women existed. The quantity of alcohol consumption rather than the trajectory may be significantly related to raised SBP, and a possible short-term influence of the most recent alcohol consumption may exist when baseline SBP is adjusted in men.

The Effect of Alcohol on Blood Pressure and Hypertension

PURPOSE

To examine the acute and chronic effects of alcohol on blood pressure (BP) and the incidence of hypertension. We discuss the most current understanding of the mechanisms underlining these effects and their associations with the putative cardioprotective effects of consumption of low-to-moderate amounts of alcoholic beverages.

RECENT FINDINGS

A recent meta-analysis confirmed findings of experimental studies, demonstrating an acute biphasic effect of ethanol on BP, decreasing up to 12 h of ingestion and increasing after that. This effect is mediated by vagal inhibition and sympathetic activation. A meta-analysis found that chronic consumption of alcoholic beverages was associated with a high incidence of hypertension in men and women; it also found that, in women, the risk begins at moderate alcohol consumption. The risks of alcohol consumption are higher in Blacks than in Asians or Caucasians. The mechanism underlying the chronic effects of alcohol on BP, and particularly the differential effect on Blacks, is still unknown. Short-term trials showed that alcohol withdrawal promotes BP reduction; however, the long-term effectiveness of interventions that aim to lower BP through the restriction of alcohol consumption has not been demonstrated. The harmful effects of alcohol on BP do not support the putative cardioprotective effect of low-to-moderate consumption of alcoholic beverages. The absence of a tangible mechanism of protection, and the possibility that this beneficial effect is biased by socioeconomic and other characteristics of drinkers and abstainers, calls into question the hypothesis that consuming low amounts of alcoholic beverages improves cardiovascular health. The evidence from investigations with various designs converge regarding the acute biphasic effect of ethanol on BP and the risk of chronic consumption on the incidence of hypertension, particularly for Blacks. These effects do not support the putative cardioprotective effect of consumption of low-to-moderate amounts of alcoholic beverages. Mechanisms of chronic BP increase and the demonstration of long-term benefits of reducing alcohol intake as a means to treat hypertension remain open questions.

Alcohol, cardiovascular disease and industry funding: A co-authorship network analysis of systematic reviews

BACKGROUND

Alcohol's effects on heart health is the site of a major scientific controversy. We conducted a co-authorship network analysis of systematic reviews on the impacts on alcohol on cardiovascular disease (CVD) in order to investigate patterns of co-authorship in the literature, with particular attention given to industry funding.

METHODS

We used Epistemonikos to identify systematic reviews. Review characteristics, influential authors, co-authorship subnetworks, prior histories of alcohol industry funding, study outcomes and citations were investigated.

RESULTS

60 systematic reviews with 231 unique authors met our inclusion criteria. 14 systematic reviews were undertaken by authors with histories of alcohol industry funding, including 5 that were funded directly by the alcohol industry itself. All 14 such reviews identified a cardioprotective effect of alcohol. These formed distinct co-authorship subnetworks within the literature. Of reviews by authors with no prior histories of alcohol industry funding, the findings were mixed, with 54% (25/46) concluding there was evidence of health protective effects. These two groups of reviews differed in other respects. Those with industry funding were more likely to study broader outcomes such as 'cardiovascular disease' or 'coronary heart disease' as opposed to specific CVD issues such as hypertension or stroke (93% [13/14] versus 41% [19/46]) (chi-squared 12.4, p < 0.001) and have more included studies (mean of 29 versus 20). They were also more widely cited by others. Over time the proportions of systematic reviews on CVD and alcohol undertaken by authors with no prior histories of alcohol industry funding has increased.

CONCLUSIONS

Systematic reviews undertaken by authors with histories of alcohol industry funding were more likely to study broader outcomes, and be cited more widely, and exclusively reported favorable conclusions.
