We conducted this cross-sectional study to investigate the independent associations between lipid metabolites and osteoporotic fractures among participants aged 40-69 years from the UK Biobank. Serum lipid, lipoprotein levels and nuclear magnetic resonance (NMR) based metabolic biomarkers were measured at the baseline. We conducted multivariable logistic analyses to investigate potential independent associations between concentrations of lipid metabolites and osteoporotic fractures in both men and women. The odds ratios (ORs) for lipid metabolites were calculated based on their lowest tertile. Over a median follow-up period of 15 years, a total of 978 men and 4515 women were diagnosed with osteoporosis, whereas 138 men and 327 women encountered incident fractures. Statistically significant disparities were identified in NMR-based metabolic biomarkers among men and women with incident fractures compared to those without. Out of the 144 distinct lipid metabolites known, 35 exhibited significant associations with incident fractures in patients diagnosed with osteoporosis. Following the adjustment for confounding factors, degree of unsaturation (p = 0.0066) and docosahexaenoic acids (p = 0.0011) in male patients increased the risk of incident fractures. And high level of different metabolites of HDL (p = 0.0153), 3-Hydroxybutyrate (p = 0.0012) and Sphingomyelins (p = 0.0036) decreased the risk of incident fractures in female patients. This outcome indicates that these identified lipid metabolites may potentially have unique roles in independently contributing to the occurrence of osteoporotic fractures., (© 2024. The Author(s).)

In recent years, significant progress has been achieved in comprehending the impact of alcohol consumption on adverse health outcomes. However, the quality of evidence remains limited. Our objective was to conduct a prospective study examining the relationship between different types of alcoholic beverages and the risk of all-cause mortality, cardiovascular disease (CVD), and chronic kidney disease (CKD), and identifying the thresholds of safe dose stratified by sex using data from the UK Biobank. 502,490 participants were enrolled. These participants were initially registered between 2006 and 2010, and underwent reassessment between 2012 and 2013. All participants completed a detailed questionnaire on their alcohol consumption, including total alcohol consumption yesterday, weekly consumption of red wine, champagne plus white wine, beer, spirits, and fortified wine. All-cause mortality and the incidence of CVD and CKD were considered as the primary outcomes. 2852 participants reported CKD during a median follow-up period of 11.94 years, while 79,958 participants reported CVD over a median follow-up period of 11.35 years. Additionally, 18,923 participants died over a median follow-up period of 11.89 years. After adjusting for variables such as age, sex, education level, smoking status, diet score, and exercise score, total alcohol consumption showed a U-shaped relationship with the risk of CVD and all-cause mortality, but showed an inverse association with the risk of CKD. Upon further classification of alcoholic beverages, our analysis revealed that red wine, champagne plus white wine, beer, spirits, and fortified wine presented a U-shaped relationship with the risk of all-cause mortality and CKD. However, spirits were positively associated with the risk of CVD, only red wine, champagne plus white wine, beer, and fortified wine showed a U-shaped relationship with the risk of CVD. The safe doses of total alcohol consumption should be < 11 g/d for males and < 10 for females, red wine consumption should be < 7 glasses/week for males and < 6 for females, champagne plus white wine consumption should be < 5 glasses/week, and fortified wine consumption should be < 4 glasses/week. Red wine, champagne plus white wine, beer, and fortified wine below the corresponding thresholds of safe dose in our analysis were significantly associated with a lower risk of all-cause mortality, CVD, and CKD. And these alcoholic beverages under safe doses exhibited a protective effect against conditions like diabetes, depression, dementia, epilepsy, liver cirrhosis, and other digestive diseases, while didn't increase the risk of cancer., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2024 the Author(s).
