Objective: This study aimed to investigate the relationship between drinking status and kidney stones occurrence among United States (US) adults who consume alcohol. Methods: We conducted a cross-sectional analysis using data from the National Health and Nutrition Examination Survey (NHANES 2007–2018). Questionnaires yielded information on alcohol consumption and kidney health. Drinking status was categorized into four groups—former, mild, moderate, and heavy—based on alcohol consumption patterns. The aim was to explore the relationship between drinking status and the prevalence of kidney stones occurrence. For this analysis, we examined a group of individuals diagnosed with kidney stones. With survey weights applied, the total weight of the group was 185,690,415. Results: We used logistic regression to measure the relationship between drinking status and the likelihood of developing kidney stones. In a fully adjusted model, former drinkers were less likely to have previously experienced kidney stones (OR 0.762, 95% CI 0.595–0.977, P < 0.05). In subgroup analysis, heavy alcohol consumption was associated with a significantly reduced likelihood of kidney stones occurrence in various populations. The adjusted odds ratios (with 95% confidence intervals) of kidney stones risk for heavy alcohol consumption were 0.745 (0.566–0.981) for young individuals, 0.566 (0.342–0.939) for older individuals, 0.708 (0.510–0.981) for individuals of white race, 0.468 (0.269–0.817) for individuals with underweight/normal BMI, 0.192 (0.066–0.560) for widowed people, 0.538 (0.343–0.843) for smoking individuals, 0.749 (0.595–0.941) for individuals without a cancer history, and 0.724 (0.566–0.925) for individuals without a stroke history. Conclusions: In US adults who consume alcohol, a negative linear relationship is apparent between drinking status and the prevalence of kidney stones, with heavy drinking showing a lower prevalence compared to former drinkers. However, the causal relationship between drinking status and kidney stones requires further investigation in future research endeavors. [ABSTRACT FROM AUTHOR]

Background: Numerous studies have shown that the dietary inflammatory index (DII) is associated with adverse health effects. However, the relationship between DII and prostate cancer (PCa) remains controversial. Although alcohol is included in DII as a dietary factor, the various adverse health effects of alcohol consumption are not only related to inflammation. On the other hand, it has been a long-standing debate whether alcohol consumption is linked to the risk of PCa. Therefore, to clarify whether drinking affects the relationship between DII and PCa, we evaluated the correlation between DII and prostate-specific antigen (PSA) based on the National Health and Nutrition Examination Survey (NHANES) database. Methods: We used data from the NHANES spanning from 2005 to 2010 to analyze the relationship between PCa and DII. Out of the 31,034 NHANES participants, we enrolled 4,120 individuals in our study, utilizing dietary intake data from a twenty-four-hour period to determine DII scores. Demographic data, physical and laboratory test results were collected to compare between low PSA and high PSA groups, and to calculate the odds ratio between both groups, we employed a logistic regression analysis. Results: In this cross-sectional investigation of PCa, drinkers and non-drinkers had different relationships between DII and PSA levels (OR: 1.2, 95% Cl: 1-1.44 vs. OR: 0.98, 95% Cl: 0.9–1.07), and DII and abstaining from alcohol were effective in reducing the incidence of PSA (p-value for significant interaction = 0.037). Conclusion: The results of our study suggest that drinking may influence the relationship between DII and PSA levels. DII is likely to be a reliable indicator for estimating PSA levels among non-drinkers, who may limit their intake of pro-inflammatory ingredients to lower the incidence and death of PCa.

• Study finds smoking status affects the association between selenium intake and PSA • Smokers had lower odds of high PSA • Interaction suggests smoking modifies selenium's effect on prostate cancer risk. Conflicting results regarding the impact of selenium on reducing prostate cancer have been reported. The current analysis aimed to understand whether there are potential factors affecting the relationship between selenium and prostate cancer. To clarify the relationship between dietary selenium intake and prostate cancer, we evaluated the correlation between dietary selenium intake and prostate-specific antigen (PSA) based on the National Health and Nutrition Examination Survey (NHANES) database. After screening the NHANES survey data from 2005 to 2010, data for 3,614 of 31,034 participants were considered suitable to include in our study. Dietary selenium intake was the independent variable of our study, while PSA was the dependent variable. We stratified participants into current, former, and never smokers and performed an interaction test on the relationship between selenium intake and PSA using multivariable logistic regression for each smoking-status subgroup. For our subgroup analysis, we grouped participants based on smoking status and investigated the association between dietary selenium intake and PSA levels. Among the 242 participants with a PSA level of 4 or higher, the mean age was 58.5 years (±12.1). After adjusting for covariates, we did not find a significant association between dietary selenium and the odds of having a high PSA level. However, we observed a significant interaction between smoking status and dietary selenium in relation to PSA levels (P =.007). Specifically, smokers had lower odds of having high PSA levels, while nonsmokers had higher odds. This suggests that smoking status may modify the effect of dietary selenium on PSA levels. Our findings suggest that smoking status affects the relationship between dietary selenium intake and PSA and that smokers are at lower odds of having a high PSA level. [ABSTRACT FROM AUTHOR]
