Prevalence and Risk Factors for Chronic Kidney Disease in Belize: A Population-based Survey

Association between alcohol consumption and chronic kidney disease: a population-based survey

BACKGROUND

Alcohol consumption is associated with both beneficial and harmful effects, and the role of alcohol consumption in chronic kidney disease (CKD) remains inconclusive. This study aimed to investigate the relationship between alcohol consumption and CKD or estimated glomerular filtration rate (eGFR).

METHODS

This study enrolled adults from the second Taiwanese Survey on Prevalences of Hypertension, Hyperglycemia, and Hyperlipidemia, conducted in 2007. Participants were categorized into frequent drinkers, occasional drinkers, and nondrinkers. The amount of alcohol consumption was assessed by standard drinks per week. The primary outcome was the presence of CKD, and the secondary outcome was the eGFR.

RESULTS

Among 3967 participants with a mean age of 47.9 years and a CKD prevalence of 11.7%, 13.8% were frequent drinkers, and 23.1% were occasional drinkers. The average amount of alcohol consumed was 3.3 drinks per week. Frequent drinkers (odds ratio [OR] 0.622, 95% confidence interval [CI] 0.443-0.874) and occasional drinkers (OR 0.597 95% CI 0.434-0.821) showed a lower prevalence of CKD than nondrinkers. Consumption of a larger number of standard drinks was associated with a lower prevalence of CKD (OR 0.872, 95% CI 0.781-0.975). Frequent drinkers and those who consumed a larger number of standard drinks per week showed higher eGFRs.

CONCLUSION

Within the range of moderate alcohol intake, those who consumed more alcohol had a higher eGFR and reduced prevalence of CKD. The potentially harmful effects of heavy drinking should be taken into consideration, and alcohol intake should be limited to less than light to moderate levels.

Prevalence and risk factors for chronic kidney disease in Indonesia: An analysis of the National Basic Health Survey 2018

Background

The prevalence of chronic kidney disease (CKD) in Indonesia is rising, but the exact extent of the burden of CKD in Indonesia is unknown. To design a screening program for individuals at high-risk, more knowledge is required regarding the prevalence and risk factors of CKD in Indonesia. The latter could have a big impact on the prevention and management of patients with CKD in Indonesia.

Methods

For this purpose, we analysed data from The National Basic Health Survey 2018 (Riset Kesehatan Dasar, Riskesdas 2018), a descriptive cross-sectional study in 34 provinces, 416 districts and 98 cities in Indonesia. We included subjects aged ≥18 years and analysed the prevalence of CKD. Using multiple logistic regression, we investigated the association between CKD and potential risk factors such as demographic factors (age, gender, occupational status, level of education), lifestyle and behaviours (consumption of salty food, consumption of fruit and vegetables, smoking, alcohol consumption, carbonated drink consumption, physical activity), comorbid conditions (hypertension, heart disease, diabetes mellitus, hepatitis, stroke, nutritional status) and others (clean water supply, pregnancy complication, access to health care).

Results

We included 389 093 subjects in this study out of 713 783 subjects that participated in Riskesdas 2018 survey. The prevalence of CKD was 0.5%. The survey included mostly younger adults age 18-59 years (83.1%) with a mean (SD) age of 44.3 (15.1) years. The majority of subjects were female (60.3%), unemployed (58.4%), and the proportion of obese subject was 25.4%. Hypertension was the major comorbid condition (40.8%), while the proportion of diabetes mellitus (DM), heart disease, stroke and hepatitis were quite low (3.3%, 2.6%, 1.7% and 0.5%; respectively). Despite the high proportion of hypertension, only 36.2% of subjects did receive a prescription for anti-hypertensive medication of which only 21.7% used this medication regularly. The multiple logistic regression analysis demonstrated that hepatitis was the strongest risk factor of CKD (odds ratio (OR) = 3.406; 95% confidence interval (CI) = 2.496-4.648), exceeding the risk of CKD in patients with physical inactivity (OR = 1.236; 95% CI = 1.128-1.354), low education status (OR = 1.307; 95% CI = 1.191-1.434), male (OR = 1.527; 95% CI = 1.398-1.668), stroke (OR = 1.916; 95% CI = 1.570-2.338), heart disease (OR = 2.941; 95% CI = 2.356-3.671), and DM (OR = 2.462; 95% CI = 1.979-3.063). We also observed that DM (OR = 4.280; 95% CI = 3.756-4.876) and male subjects (OR = 1.474; 95% CI = 1.352-1.606) were identified as independent risk factors for CKD in hepatitis-positive subjects.

Conclusions

This population-based survey confirmed the increasing burden of CKD in Indonesia and suggested that besides traditional metabolic risk factors, viral hepatitis has proven to be an independent risk factor for CKD in Indonesia. Furthermore, the risk of CKD is greater in male hepatitis patients with DM. The result of this study demonstrates the need for an aggressive screening program for patients with a high risk for the development of CKD. Apart from patients with traditional cardiometabolic risk factors, such a program should include patients with viral hepatitis.
