Leisure activities were interviewed about their engagement in 6 typical activities (i.e., housework tasks, personal outdoor activities, gardening, rearing domestic animals/pets, playing cards/mahjong, and attending in social activities). A weighted genetic risk score (GRS) was constructed based on 11 lifespan-related loci and divided into two groups according to the median scores (0.21). The Cox proportional risk model was used to assess the association between different types of PAs and genetic risk with all-cause mortality.</p><p><strong>Results: </strong>During 63,832 person-years of follow-up, 5678 deaths were documented. The hazard ratios (HRs) for all-cause mortality between different PAs (lowest activity vs highest activity) were 0.85 (95% CI 0.79-0.92) for leisure activities, 0.93 (95% CI 0.87-0.99) for regular exercise, and 0.93 (95% CI 0.86-1.01) for physical work, respectively. Compared with low leisure activities, high leisure activities were associated with 16% reduction in all-cause mortality for individuals with low longevity GRS (HR 0.84, 95% CI 0.76-0.93), and 14% reduction in all-cause mortality for individuals with high longevity GRS (HR 0.86, 95% CI 0.78-0.96). Adherence to regular exercise was associated with 11% reduction in all-cause mortality for individuals with high longevity GRS (HR 0.89, 95% CI 0.81-0.97), while there was no statistically significance for those with low longevity GRS (HR 0.97, 95% CI 0.89-1.06) compared with those without regular exercise. There was no additive or multiplicative interaction between PAs and longevity genetics (P<sub>interaction</sub> > 0.05).</p><p><strong>Conclusions: </strong>Leisure activities, as a low-risk, low-intensity, simple and inexpensive PA, rather than regular exercise, might bring the greatest health benefits, even for individuals with less longevity genes, highlighting the importance of providing individualized PA recommendations for older adults.</p>","PeriodicalId":9188,"journal":{"name":"BMC Medicine","volume":"23 1","pages":"361"},"PeriodicalIF":7.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12220457/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144538886","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition to effects on arterial vascular tone, associations between serum uric acid concentrations-even in the physiological range-and arterial hypertension and vascular-mediated end-organ damage due to an impact on vascular stiffness have been postulated.</p><p><strong>Methods: </strong>Therefore, we aim to investigate a possible cross-sectional association between serum uric acid concentrations in the physiological range and differences in arterial pulse wave velocity (PWV), an indicator of vascular remodeling, with a focus on possible differences between female and male individuals. We analyzed cross-sectional phenotypic and laboratory parameters, including PWV from 70,649 individuals in the population-based German National Cohort (NAKO) in a sex-specific manner. In parallel, we applied a machine learning approach to identify and quantify factors associated with PWV in a hypothesis-free manner.</p><p><strong>Results: </strong>Our analysis uncovered a positive association between serum uric and PWV which was detected even if only individuals with urate values in the physiological range were included (n = 64,095). This correlation was more pronounced in women than in men. In multivariable linear regression models, we observed an association of uric acid (mmol/l) with PWV (m/s) of β = 1.12 (95% confidence interval (CI): 0.78; 1.45) in males and β = 1.35 (1.05; 1.66) in females, independent of other factors known to affect vascular stiffness. In addition, the machine learning approach identified uric acid as a major factor associated with PWV. The positive association was not restricted to hyperuricemia but evident even in the physiological concentration range. Based on the data from studies on the impact of aging on PWV, it is estimated that an increase in serum uric acid concentration by 0.1 mmol/l corresponds to an increase of approx. 7 years of age in females and of 4 years in males.</p><p><strong>Conclusions: </strong>Already in the physiological concentration range, uric acid is positively associated with parameters of arterial stiffness. This association is more pronounced in females as compared to males. This finding provides a mechanistic explanation for the increased risk of vascular end-organ damage associated with higher serum uric acid concentrations and supports the observed greater benefit of therapeutic uric acid lowering in female. Future intervention studies have to address the mechanistic causality of the observed effect.</p>","PeriodicalId":9188,"journal":{"name":"BMC Medicine","volume":"23 1","pages":"356"},"PeriodicalIF":7.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12211650/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144538887","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
