Association between alcohol intake and incident hypertension in the Korean population

Lifestyle Factors, Sociodemographic Characteristics and Incident Hypertension: A Prospective Analysis of the Korean National Health Insurance Service Sample Cohort

BACKGROUND

Hypertension is a significant chronic disease globally, and lifestyle modifications are crucial for the prevention of this disease. We conducted a longitudinal analysis of the associations between lifestyle factors and the incidence of hypertension, stratified by sociodemographic characteristics.

METHODS

We analyzed 113,022 adults (65,315 men), aged 20 years or older from the Korean National Health Insurance Service-National Sample Cohort 2.0 who participated in health screening between 2002 and 2003. Lifestyle factors (smoking, drinking, physical activity) were assessed at baseline using self reports, and incident hypertension was defined based on physician diagnoses. Cox proportional hazards regression models were used to assess associations.

RESULTS

During an 11.6-year follow-up, 26,812 new cases of hypertension were identified. The risk of hypertension was high among men and women who smoked over 20 cigarettes daily (men: hazard ratio [HR]: 1.15; 95% confidence interval [CI], 1.08-1.21; women: HR: 1.62; 95% CI 1.17-2.25) and those who drank over 1.5 bottles of alcohol daily (men, HR: 1.18; 95% CI, 1.12-1.24; women, HR: 1.23; 95% CI 1.02-1.47). These associations tended to be high in high-income men (HR: 1.09; 95% CI, 1.04-1.14), low-income women (HR: 1.19; 95% CI, 1.05-1.35) and non-obese women (HR: 1.13; 95% CI, 1.01-1.27) who currently smoked. Physical activity was inversely associated with incident hypertension in men (HR: 0.96; 95% CI, 0.93-0.99).

CONCLUSIONS

Unhealthy lifestyle factors, such as heavy smoking and drinking, was associated with an increased risk of hypertension, with variations by income, BMI, and sex. These findings underscore the importance of tailored, population-specific prevention strategies to address hypertension disparities.

Alcohol Intake and Risk of Hypertension: A Systematic Review and Dose-Response Meta-Analysis of Nonexperimental Cohort Studies

BACKGROUND

Alcohol consumption has been associated with higher blood pressure and an increased risk of hypertension. However, the possible exposure thresholds and effect-modifiers are uncertain.

METHODS

We assessed the dose-response relationship between usual alcohol intake and hypertension incidence in nonexperimental cohort studies. After performing a systematic literature search through February 20, 2024, we retrieved 23 eligible studies. We computed risk ratios and 95% CI of hypertension incidence using a nonlinear meta-analytic model based on restricted cubic splines, to assess the dose-response association with alcohol consumption.

RESULTS

We observed a positive and almost linear association between alcohol intake and hypertension risk with risk ratios of 0.89 (0.84-0.94), 1.11 (1.07-1.15), 1.22 (1.14-1.30), and 1.33 (1.18-1.49) for 0, 24, 36 and 48 g/d, respectively, using 12 g alcohol/d as the reference value. In sex-specific analyses, the association was almost linear in men over the entire range of exposure but only observed above 12 g/d in women, although with a steeper association at high levels of consumption compared with men. The increased risk of hypertension above 12 to 24 g alcohol/d was similar in Western and Asian populations and considerably greater in White than in Black populations, mainly due to the positive association in women at moderate-to-high intake.

CONCLUSIONS

Overall, our results lend support to a causal association between alcohol consumption and risk of hypertension, especially above an alcohol intake of 12 g/d, and are consistent with recommendations to avoid or limit alcohol intake. Sex and ethnicity appear to be major effect-modifiers of such association.

Risk of diabetes and hypertension in a population with alcohol use disorders

BACKGROUND

A population-based follow-up study assessing the risk of developing hypertension and diabetes associated with alcohol use disorder (AUD) is crucial. We investigated this relationship by using insurance claims data from Taiwan.

METHODS

From the claims data, an AUD cohort (N = 60,590) diagnosed between 2000 and 2006 and a non-AUD comparison cohort (N = 60,590) without the diagnosis of hypertension or diabetes at baseline were established and matched by propensity scores estimated by baseline demographic status and the Charlson comorbidity index (CCI). We assessed the incidence rates of hypertension and/or diabetes at the end of 2016 and used Cox's method to estimate the related hazard ratios (HRs) and 95% confidence intervals (CIs).

RESULTS

Relative to the comparison cohort, the AUD cohort had an approximately 1.70-fold higher incidence of hypertension (35.1 vs. 20.7 per 1,000 person-years), with an adjusted HR (aHR) of 1.72 (95% CI: 1.68-1.76), 2.16-fold higher incidence of diabetes (20.2 vs. 9.36 per 1,000 person-years), with an aHR of 2.18 (95% CI: 2.11-2.24), and 1.91-fold higher incidence of both diabetes and hypertension (10.3 vs. 5.38 per 1,000 person-years) with an aHR of 2.02 (95% CI: 1.94-2.10). The incidence rates of all outcomes were greater in men than in women, whereas the HRs were greater for AUD in women than for AUD in men relative to the respective comparison patients. The risk increased further for subjects with CCI ≥ 1, which was higher in the AUD cohort.

CONCLUSIONS

The increased risk of developing diabetes and hypertension in patients with AUD, especially the differences noted according to gender, indicates that clinicians should address potential comorbidities in these patients.

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.

Risk of Hypertension and Type 2 Diabetes in Relation to Changes in Alcohol Consumption: A Nationwide Cohort Study

Little is known about the risk of hypertension and type 2 diabetes in relation to changes in frequency and amount of alcohol consumption. This study investigated associations between changes in alcohol consumption and the risk of both conditions. This study included 96,129 individuals without hypertension and/or diabetes mellitus aged ≥ 20 years between 2006 and 2008, with follow-up until 31 December 2015. This study identified 29,043 and 18,784 incident cases of hypertension and type 2 diabetes, respectively, during an average follow-up period of 6.2 ± 2.6 and 6.9 ± 1.9 years. This study measured changes in frequency and amount of alcohol consumption using standardized self-administered questionnaires over approximately 2 years. Hazard ratio (HR) and 95% confidence interval (CI) were calculated for the respective risks of the two conditions. Repeated occasional or frequent binge drinking was associated with an increased risk of hypertension (HR: 1.16 or 1.32; 95% CI: 1.11, 1.21 or 1.16, 1.51) and type 2 diabetes (HR: 1.14 or 1.36; 95% CI: 1.09, 1.20 or 1.17, 1.58) compared with continuous nondrinking. Reductions as well as increases in frequency of alcohol consumption among binge drinkers were associated with higher hypertension (HR: 1.29 or 1.30; 95% CI: 1.11, 1.49 or 1.13, 1.49) and type 2 diabetes (HR: 1.26 or 1.56; 95% CI: 1.06, 1.49 or 1.34, 1.81) risk. This study demonstrated that repeated binge drinking, even with a reduction of weekly alcohol consumption frequency, was associated with a higher risk of hypertension and type 2 diabetes.

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 according to socioeconomic and hypertensive status among Korean adults

This research investigated variations in alcohol consumption by socioeconomic factors and hypertensive status in South Korean adults, aged ≥19 years. This is a secondary data analysis using the Korea National Health and Nutrition Examination Survey (KNHANES). Alcohol intake by socioeconomic and hypertensive status was examined using data from the 2013 to 2016 KNHANES. Total participants were 19,641 adults, with 8,123 men and 11,518 women. Consumption of alcohol in the Korean population was estimated from a single 24-hour dietary recall. Alcohol intake differed, according to socioeconomic status, and, particularly, by occupation among Korean adults. Women with lower education consumed more alcohol daily than those with a higher education (p = 0.018). Furthermore, adult men with hypertension consumed a greater amount of alcohol daily, 30.9 g, than those with pre-hypertension, 23.7 g, followed by those without hypertension, 15.9 g (p < 0.001). In women, adults with pre-hypertension and hypertension consumed more alcohol daily, 9.4 g and 9.0 g, respectively, than those without, 6.6 g (p < 0.001). In addition, men with hypertension who were unaware of their disease and those who were cognizant consumed a higher amount of alcohol daily, 32.4 g and 28.6 g, respectively, than individuals without hypertension, 19.7 g (p < 0.001). Moreover, men with hypertension who had not been treated for hypertension and those in treatment consumed a greater amount of alcohol daily, 32.6 g and 28.0 g, respectively, than those without hypertension, 19.7 g (p < 0.001). In conclusion, Korean adults consume alcohol differently by socioeconomic status, and alcohol intake was more prevalent among people with hypertension.

Association between the incidence of hypertension and alcohol consumption pattern and the alcohol flushing response: A 12-year follow-up study

BACKGROUND

Alcohol consumption is associated with hypertension, and this association depends on the alcohol consumption pattern and alcohol flushing response. In this 12-year follow-up study, we investigated the relationship between the alcohol consumption pattern and incidence of hypertension in the Korean population.

METHODS

We analyzed 1,366 Korean participants in the Ansung-Ansan cohort study without hypertension at baseline. The subjects were classified into four alcohol consumption patterns: never-drinking, light alcohol consumption, moderate alcohol consumption, and heavy alcohol consumption, and as flushers or non-flushers in response to alcohol.

RESULTS

In flushers, moderate and heavy alcohol consumption patterns increased the risk of incident hypertension compared with never-drinkers [moderate: HR 1.811 (95% CI 1.084-3.028); heavy: HR 2.494 (95% CI 1.185-5.247)], but non-flushers were not associated with increased risk of incident hypertension according to the alcohol consumption pattern. In addition, a heavy alcohol consumption pattern increased the risk of hypertension among flushers compared with non-flushers [HR 2.232 (95% CI 1.054-4.728)].

CONCLUSION

In this 12-year follow-up study, we observed that moderate and heavy alcohol consumption was associated with an increased risk of hypertension in flushers. Especially, a heavy alcohol consumption pattern in flushers markedly increased the risk of hypertension.

Mortality Rate Due to Circulatory and Alcohol-Dependent Diseases in Different Climatic Zones of Russia

AIM

Evaluation of the impact of climatic factors on the formation of mortality due to circulatory diseases and a group of diseases related to alcohol consumption identified as alcohol-dependent.

METHODS

The study subject was the adult population residing in different climatic zones of Russia: in the second, third and fourth zones, with different conditions: average annual temperature (5.2°C; 1-2°C; -2.0°C), snow cover duration (≤ 150 days, ≤ 180 days, ≈ 220 days) sunshine duration and the presence of polar night and polar day in the territory of the fourth climatic zone. The assessment "impact-case of death" was carried out by calculating the standardized incidence ratio (SIR) with 95% confidence intervals (CI) for circulatory system diseases (CSD) and alcohol-dependent diseases (ADD) in accordance with the international classification of diseases (ICD-X).

RESULTS

The SIR of death from alcohol-dependent diseases for the female population in the 4th climatic zone (Murmansk Region) was the highest: the SIR of death from ADD 1.87; 95% CI (1.5-2.7), the SIR of death from CSD 1.3; 95% CI (1.2-2.3). For the female population in the 3rd climatic zone (Novosibirsk Region), the SIR of death has amounted to: SIRADD 1.52; 95% CI (1.2-1.87), SIRCSD 1.14; 95 CI (1.01-1.3). Living in the 3rd climatic zone was not so important for the health of the male population: the SIR of death from CSD 1.1; 95% CI (1.05-1.13); the SIR of death from ADD 0.8; 95% CI (0.65-0.98). However, living in the 4th climatic zone (Murmansk Region) poses a higher risk of death for the male population: SIRCSD 1.22 (22.0%); 95% CI (1.02-3.95); SIRADD 1.45 (45.0%); 95% CI (0.98-2.1).

CONCLUSION

Living in high northern latitudes contributes to higher levels of mortality, both female and male, from circulatory and alcohol-dependent diseases.
