Aim: To determine the associations between the Chinese visceral adiposity index (CVAI) and the risks of all‐cause and cause‐specific mortality. Materials and Methods: A total of 3 916 214 Chinese adults were enrolled in a nationwide population cohort covering all 31 provinces of mainland China. The CVAI was calculated based on age, body mass index, waist circumference, and triglyceride and high‐density lipoprotein cholesterol concentrations. We used a Cox proportional hazards regression model to determine the hazard ratios and 95% confidence intervals (CIs) for risk of mortality associated with different CVAI levels. Results: The median follow‐up duration was 3.8 years. A total of 86 158 deaths (34 867 cardiovascular disease [CVD] deaths, 29 884 cancer deaths, and 21 407 deaths due to other causes) were identified. In general, after adjusting for potential confounding factors, a U‐shaped relationship between CVAI and all‐cause mortality was observed by restricted cubic spline (RCS). Compared with participants in CVAI quartile 1, those in CVAI quartile 4 had a 23.0% (95% CI 20.0%–25.0%) lower risk of cancer death, but a 23.0% (95% CI 19.0–27.0) higher risk of CVD death. In subgroup analysis, a J‐shaped and inverted U‐shaped relationship for all‐cause mortality and cancer mortality was observed in the group aged < 60 years. Conclusions: The CVAI, an accessible indicator reflecting visceral obesity among Chinese adults, has predictive value for all‐cause, CVD, and cancer mortality risks. Moreover, the CVAI carries significance in the field of health economics and secondary prevention. In the future, it could be used for early screening purposes. [ABSTRACT FROM AUTHOR]

Kidney transplant (KT) recipients are known to be at risk of developing several cancer types; however, cancer mortality in this population is underinvestigated. Our study aimed to assess the risk of cancer death among Italian KT recipients compared to the corresponding general population. A cohort study was conducted among 7373 individuals who underwent KT between 2003 and 2020 in 17 Italian centers. Date and cause of death were retrieved until 31 December 2020. Indirect standardization was used to estimate standardized mortality ratios (SMRs) and corresponding 95% confidence intervals (CIs). Cancer was the most common cause of death among the 7373 KT recipients, constituting 32.4% of all deaths. A 1.8‐fold excess mortality (95% CI: 1.59‐2.09) was observed for all cancers combined. Lymphomas (SMR = 6.17, 95% CI: 3.81‐9.25), kidney cancer (SMR = 5.44, 95% CI: 2.97‐8.88) and skin melanoma (SMR = 3.19, 95% CI: 1.03‐6.98) showed the highest excess death risks. In addition, SMRs were increased about 1.6 to 3.0 times for cancers of lung, breast, bladder and other hematopoietic and lymphoid tissues. As compared to the general population, relative cancer mortality risk remained significantly elevated in all age groups though it decreased with increasing age. A linear temporal increase in SMR over time was documented for all cancers combined (P <.01). Our study documented significantly higher risks of cancer death in KT recipients than in the corresponding general population. Such results support further investigation into the prevention and early detection of cancer in KT recipients. [ABSTRACT FROM AUTHOR]
