Background: Inflammation is crucial in the pathogenesis of lower urinary tract symptoms (LUTS) in men. Diet modulates inflammation. Therefore, diet could be a modifiable factor in male LUTS prevention and treatment. We aimed to investigate the association between dietary inflammatory potential and male LUTS., Methods: We used two cycles of National Health and Nutrition Examination Survey (NHANES) with self-report LUTS data. We calculated the dietary inflammatory index (DII) based on a 24 h diet recall and evaluated male LUTS. Clinical LUTS was defined as two or more coexisting symptoms. We used univariate and multivariate logistic regression models, the smooth curve fitting to analyze the relationship between clinical LUTS and the DII score. Subgroup analyses were conducted., Results: We observed a positive non-linear relationship between clinical LUTS and DII. We found that when DII was higher than the inflection point 2.39, a 1-unit increase in DII was associated with 26.1% higher adjusted odds of clinical LUTS. Subgroup analyses showed that the DII score was only positively correlated with clinical LUTS risk in non-drinkers, smokers, and non-obese people (DII >2.39)., Conclusions: Inflammation might be the key mechanism bridging dietary consumption to male LUTS. Excessive pro-inflammatory food intake (DII >2.39) warrants special vigilance, especially for non-drinkers, smokers, and non-obese men.

Purpose: This study investigated the association between Dietary Inflammatory Index and sex hormones in a large, nationally representative adult male sample., Materials and Methods: We utilized data from the 2013-2014 and 2015-2016 National Health and Nutrition Examination Survey. Males aged ≥20 years who provided a 24-hour dietary intake history and underwent serum sex hormone testing were included in analysis. Weighted proportions and multivariable analysis controlling for age, race, energy, smoking status, education level, body mass index and time of venipuncture were used to evaluate the associations between Dietary Inflammatory Index and sex hormones., Results: For 4,151 participants, Dietary Inflammatory Index ranged from -5.05 to 5.48. Mean±SD total testosterone was 419.30±176.27 ng/dl. Mean±SD total testosterone was lower among men in the highest tertile compared with men in the lowest tertile group (410.42±171.97 vs 422.71±175.69, p <0.001). A per unit increase in Dietary Inflammatory Index was related to 4.0% (95% CI 0.5-7.6) higher odds of testosterone deficiency. In the fully adjusted multivariable model, males in Dietary Inflammatory Index tertile 3 (the most pro-inflammatory) had 29.6% (3.1-63.0) higher odds of testosterone deficiency than those in tertile 1 (p trend=0.025). Interaction tests revealed no significant effect of body mass index on the association of Dietary Inflammatory Index with testosterone deficiency and all sex hormone parameters., Conclusions: Men adhering to a more pro-inflammatory diet appear to have a higher risk of testosterone deficiency, indicating the important role of diet in male reproductive health.

The purpose of this study was to evaluate the association between dietary inflammatory index (DII) and urinary incontinence (UI) among a representative sample of the US women. We performed a cross-sectional analysis of women younger than 65 years using the 1999 to 2016 NHANES (National Health and Nutrition Examination Survey) populations. DII were calculated based on baseline dietary intake using 24-h dietary recalls. UI was determined and categorized by self-reported questions. Multivariable logistic regression models were used to assess the association between DII and UI. Stratified linear regression models were applied to test for interaction in prespecified subgroup of interest. A total of 13,441 women age between 20 and 65 years were included in the final analysis. Of these participants 3230 (24.03%) complained of urgency UI, 5276 (39.25%) complained of stress UI and 2028 (15.09%) complained of mixed UI. On multivariate analysis, analysis with DII categorized as quartiles revealed significantly increase odds of urgency UI in the most pro-inflammatory quartile compared to the most anti-inflammatory quartile (OR 1.24, 95% CI 1.07-1.44, P = 0.004 for trend) in full adjustment model. Similar results were observed in SUI (OR 1.14, 95% CI 1.00-1.30, P = 0.021 for trend) and MUI (OR 1.20, 95% CI 1.02-1.43, P = 0.022 for trend). More pro-inflammatory diets, as presented by higher DII scores are associated with an increased likelihood of UI in American women younger than 65 years. Further studies are needed to explore the possible physiological mechanism and evaluate the potential therapeutic implications.

This study used National Health and Nutrition Examination Surveys data from 1999 to 2006 to investigate the association between dietary inflammatory potential, represented by dietary inflammatory index (DII) scores, and the risk of sarcopenia in U.S. adults. A total of 25,781 participants were included in the study. The DII scores were calculated based on dietary information collected from 24-hour recalls. Men and women were classified as sarcopenic if appendicular lean mass (ALM) adjusted for BMI (ALM BMI ) was <0.789 or <0.512, respectively. The covariates included comorbidities, dietary data, demographic data, and physical examination data. In a full-adjusted model, each unit of increase in DII score was associated with a 12% increase in risk of sarcopenia. When categorizing sarcopenia into tertiles, the adjusted effect size (relative to Tertile1) was 1.26 (95% CI, 1.07, 1.47) for Tertile 2 and 1.55 (95% CI, 1.31, 1.83) for Tertile 3. The trend test showed that the risk of sarcopenia increased with increasing DII tertiles, (P <0.0001). These findings demonstrate that dietary inflammatory potential correlates positively with the risk of sarcopenia and suggest that making ones diet inflammatory may reduce the incidence of sarcopenia and its associated negative health outcomes.

Objective: This study investigated the relationship between spiritual well-being (SWB) and various aspects of health-related quality of life (HRQL) of college students., Participants and Methods: Two hundred twenty-five participants were surveyed during October 2010 to assess SWB and HRQL using the Spiritual Well-Being Scale and questions from the Centers for Disease Control and Prevention's scale for HRQL, respectively. Hierarchical multiple linear regression analyses tested the relationship between SWB and multiple measures of HRQL while controlling for sex, age, and race., Results: Participants who reported higher SWB scores were more likely to participate in religious-type activities and report better HRQL compared with students who reported a moderate sense of SWB. Jointly, SWB and participation in religious activities explained 18% of the variance in HQRL in this sample., Conclusions: SWB made a significant contribution to HRQL in a sample of college students. Such a relationship should be considered by campus health program planners to improve the quality of life of young adults.
