Of the 62,168 study participants, 17.5% individuals fulfilled the diagnosis for the cardiometabolic risk factors clustering (18.1% boys and 16.9% girls), and 8.3% were defined as having the HW phenotype, with 8.2% in boys and 8.5% in girls. A total of 6.6% of the participants were classified as having the HWHtR phenotype (8.0% in boys and 5.2% in girls), 34.3% of the participants had high WHR (32.8% in boys and 40.0% in girls). For different cardiometabolic risk factors, 25.7% had elevated BP, 0.3% had impaired FPG, 12.6% had low HDL, 3.0% had elevated LDL, 26.8% had elevated TG, and 5.4% had hypercholesterolemia. Boys had significantly higher SBP, DBP, and FPG than girls (P < 0.05). Girls had significantly higher TG, LDL, and TC than boys (P < 0.05) (Table 1 and Supplementary Table S1, available in www.besjournal.com).

Comparisons were conducted between the participants with and without the HW, HWHtR, and WHR phenotypes. As the results in Supplementary Tables S2–S4 (available in www.besjournal.com) showed, the participants with the HW, HWHtR or WHR phenotypes had significantly higher levels of LDL, TG, TC, and BP, as well as higher cardiometabolic health risk. Moreover, the participants had lower HDL levels than those without these phenotypes. Additionally, the difference of the level of FPG between the participants with and without those phenotypes was insignificant.

Multivariate adjusted ORs (95% CIs) for cardiometabolic health risk factors among the HW, HWHtR, and WHR phenotypes are presented in Table 2. With adjustment of age and sex, and BMI, the risk of cardiometabolic health risk factors in the HW or HWHtR phenotype was significantly higher than those without the phenotype among children (HW: OR = 10.79, 95% CI: 9.28–12.55; HWHtR: OR = 9.21, 95% CI: 7.45–11.39). The risks of low HDL, elevated LDL, elevated TC, and high BP were also significantly higher for children with these phenotypes compared with those for children without the HW, HWHtR or WHR phenotype. After adjusting for age, sex, BMI, area, and family income by multivariate logistic regression, the risk of cardiometabolic health risk factors clustering in the HW phenotype was 11.22-fold higher than that in the non-HW group (OR = 12.22, 95% CI: 9.54–15.67). The risk of cardiometabolic health risk factors clustering in the HWHtR phenotype was also higher that than in the non-HWHtR group (HW: OR = 9.70, 95% CI: 6.93–13.58). Those with the HW phenotype were more likely to have low HDL, elevated LDL, elevated TC, and high BP compared with non-HW group. Additionally, except for LDL and TC, there was no significant difference between the HWHtR and HW phenotypes in the OR of risk factors for cardiometabolic risk factors clustering after adjustment of the covariates. The risk of elevation of LDL with the HWHtR phenotype was significantly higher than that with the HW phenotype (HW: OR = 2.96, 95% CI: 1.84–4.75; HWHtR: OR = 6.87, 95% CI: 3.58–13.19). The OR(95%CI) for risk of elevated TC is 3.89 (95%CI: 2.65-5.73) and 4.94 (95%CI: 2.88-8.47) for HW and HWHtR phenotype, respectively. Compared with children with the HW or HWHtR phenotype, the risk of cardiometabolic risk factors clustering in the WHR phenotype was much lower and insignificant.

The results of multivariate logistic regression analysis of cardiometabolic health risk factors of the HW, HWHtR, and WHR phenotypes by sex and age stratified according to model 2 are shown in Supplementary Tables S5–S6 (available in www.besjournal.com) and Figures 1–2. The results after stratification by sex and age were similar to those without stratification. The WHR phenotype had a significantly lower and more insignificant risk of cardiometabolic risk factor aggregation than children with the HW or HWHtR phenotypes.

Predictive Ability of Hypertriglyceridemic Waist, Hypertriglyceridemic Waist-to-Height Ratio, and Waist-to-Hip Ratio for Cardiometabolic Risk Factors Clustering Screening among Chinese Children and Adolescents
-
Abstract:
Objective Hypertriglyceridemic waist (HW), hypertriglyceridemic waist-to-height ratio (HWHtR), and waist-to-hip ratio (WHR) have been shown to be indicators of cardiometabolic risk factors. However, it is not clear which indicator is more suitable for children and adolescents. We aimed to investigate the relationship between HW, HWHtR, WHR, and cardiovascular risk factors clustering to determine the best screening tools for cardiometabolic risk in children and adolescents. Methods This was a national cross-sectional study. Anthropometric and biochemical variables were assessed in approximately 70,000 participants aged 6–18 years from seven provinces in China. Demographics, physical activity, dietary intake, and family history of chronic diseases were obtained through questionnaires. ANOVA, χ2 and logistic regression analysis was conducted. Results A significant sex difference was observed for HWHtR and WHR, but not for HW phenotype. The risk of cardiometabolic health risk factor clustering with HW phenotype or the HWHtR phenotype was significantly higher than that with the non-HW or non-HWHtR phenotypes among children and adolescents (HW: OR = 12.22, 95% CI: 9.54-15.67; HWHtR: OR = 9.70, 95% CI: 6.93-13.58). Compared with the HW and HWHtR phenotypes, the association between risk of cardiometabolic health risk factors (CHRF) clustering and high WHR was much weaker and not significant (WHR: OR = 1.14, 95% CI: 0.97-1.34). Conclusion Compared with HWHtR and WHR, the HW phenotype is a more convenient indicator withhigher applicability to screen children and adolescents for cardiovascular risk factors. -
