Insights
Hyperuricemia (HUA) is linked to metabolic syndrome (MetS) and cardiovascular disease (CVD). This study found HUA is strongly associated with MetS in both sexes, with a greater synergistic risk in women combining MetS and unhealthy lifestyles.
Area of Science:
- Metabolic Health
- Cardiovascular Health
- Sex-Based Medicine
Background:
- Hyperuricemia (HUA) is a growing concern due to its links with metabolic syndrome (MetS) and cardiovascular disease (CVD), increasing mortality.
- Unhealthy behaviors, MetS, and HUA can interact synergistically, elevating risk factors.
- Emerging evidence suggests sex-based differences in HUA's associations with risk factors.
Purpose of the Study:
- To investigate sex-based differences in the relationships between HUA and MetS, CVD risk factors, and lifestyle behaviors.
- To evaluate the joint effects of MetS and unhealthy lifestyles on HUA risk, stratified by sex.
Main Methods:
- Cross-sectional study using Korean National Health and Nutritional Examination Survey data (2016-2018).
- Multivariable logistic regression analysis to calculate adjusted odds ratios (ORs) and 95% confidence intervals (CIs).
- Subgroup analyses were performed based on sex and the presence of MetS with or without unhealthy lifestyle factors (tobacco use, alcohol intake).
Main Results:
- Significant associations between MetS and HUA were observed in both men and women, irrespective of smoking or alcohol consumption.
- The association between MetS and HUA was stronger in women.
- A synergistic effect of MetS and lifestyle factors on HUA risk was noted, particularly in women, with up to a fourfold increased risk compared to the reference group.
Conclusions:
- Sex-based differences exist in the associations between HUA, MetS, CVD risk factors, and lifestyle behaviors.
- A stronger synergistic effect of MetS and unhealthy lifestyles on HUA risk in women highlights the need for sex-specific clinical strategies.
- Tailored strategies are necessary to mitigate HUA complications and their socio-economic burden, considering sex-based variations.
Abstract:
Hyperuricemia (HUA) has become a significant medical concern due to its complications and links to metabolic syndrome (MetS) and cardiovascular disease (CVD), which result in increased mortality. The pathogenic processes associated with unhealthy behaviors, MetS, and HUA can be cooperative and potentially synergistic in the activation of risk factors. Recent research has shown sex-based differences in the relationship between HUA and its associated risk factors. This study aimed to investigate these differences, particularly in the context of MetS and CVD risk factors and unhealthy lifestyles. We also aimed to evaluate the joint effects of these factors based on sex. We conducted a cross-sectional study using nationally representative survey data from the Korean National Health and Nutritional Examination Survey 2016-2018. We performed multivariable logistic regression analysis, calculating adjusted odds ratios (ORs) with their 95% confidence intervals (CIs). We also conducted subgroup analyses based on sex and the presence of MetS with or without unhealthy lifestyle factors (tobacco use, alcohol intake). We found sex-based differences in the relationships between HUA and MetS, CVD risk factors, and lifestyle behaviors. Our major finding was a significant association between MetS and HUA in both men and women, regardless of alcohol consumption and smoking status, and this association was stronger in women. We also observed a synergistic effect of MetS and lifestyle factors on the risk of HUA, particularly in women, in whom the risk of HUA increased up to four times compared to the reference group. A sex-based clinical strategy for HUA is necessary to reduce related complications and their socio-economic burden.
