Sex differences for predicting metabolic syndrome by adipose dysfunction markers in institutionalized elderly

Aims Recent studies have emphasized that metabolic syndrome (MetS) was the most important modifiable risk factor for cardiovascular and cerebrovascular diseases in the institutionalized elderly. In addition, the occurrence of MetS was higher in those with longer age-adjusted institutionalization time. The present study was conducted to assess predictive value of markers of adipose tissue dysfunction for the early screening of MetS in this population. Methods and results Two hundred and eleven institutionalized older adults (132 women, aged 74.3 +/- 7.3 years; 79 men, aged 71.5 +/- 7.3 years) were enrolled in the current cross-sectional study. Lipid accumulation product (LAP), visceral adiposity index (VAI), body adiposity index (BAI), and triglycerides (TG)/high-density lipoprotein (HDL)-cholesterol ratio were determined. The receiver operating characteristic curve was calculated to compare the area under the curve of each index. The total prevalence of MetS was 23.8%. In female group, VAI and TG/HDL ratio presented moderate-high sensitivity (77.78% and 78.38%, respectively) and specificity (77.62% and 73.49%, respectively). In males group, LAP presented moderate-high sensitivity (75%) and specificity (76.9%). Conclusion Gender played a key role on the prediction of MetS by adipose dysfunction markers in institutionalized elderly. Accordingly, VAI and TG/HDL-cholesterol ratio showed the highest predictive value for MetS in female elderly. LAP was the strongest predictor of MetS in male elderly.

Automated summary

Recent studies have highlighted the importance of metabolic syndrome (MetS) as a modifiable risk factor for cardiovascular and cerebrovascular diseases in institutionalized elderly. The study found that markers of adipose tissue dysfunction, such as visceral adiposity index (VAI) and triglycerides (TG)/high-density lipoprotein (HDL) ratio, had the highest predictive value for MetS in female elderly, while lipid accumulation product (LAP) was the strongest predictor for MetS in male elderly.
