Sex/gender differences in metabolic syndrome among cancer survivors in the US: an NHANES analysis

BackgroundThe purpose of this study was to assess the association of metabolic syndrome (MetS) and its individual components in cancer survivors (CS) by gender, in comparison to participants without a history of cancer who have at least one chronic disease (CD) and those without a chronic disease diagnosis (NCD).MethodsData from participants 40 years and older (n = 12,734) were collected from the 2011 to 2018 National Health and Nutrition Examination Survey dataset. MetS was defined based on the National Cholesterol Education Program's Adult Treatment Panel III. Chi-square test and multivariate-adjusted logistic regression was used to assess group comparisons and associations respectively.ResultsCompared to NCD, CS and CD men had increased odds of meeting MetS, OR 2.60 (CI 1.75-3.87) and OR 2.18 (CI 1.59-2.98) respectively. For women, CS and CD participants also had higher odds of meeting MetS criteria compared to their healthy counterparts, OR 2.05 (CI 1.44-2.93) and OR 2.14 (CI 1.63-2.81) respectively. In subgroup analysis by cancer site, CS men with a history of hematologic malignancies (OR 4.88, CI 1.30-18.37) and CS women with cervical cancer (OR 4.25, CI 1.70-10.59) had highest odds of developing MetS, compared to NCD. CS men also showed a strong association with elevated waist circumference, low high density lipoprotein-c, and elevated triglycerides, even by cancer site, but there were no consistent findings among women.ConclusionThis study indicates that CS men have a strong association with MetS, especially among those with blood-related cancers.
