ABSTRACT
BACKGROUND: Most children with congenital heart disease (CHD) require surgical repair, and postoperative rehabilitation is an essential step to restore the quality of life. The present study constructs and confirms the International Classification of Functioning, Disability, and Health for Children and Youth core set for children with congenital heart disease 1 year after surgery (ICF-CY-CHDS). METHODS: From February 2021 to August 2021, 340 children aged 3-6 years after CHD surgery were evaluated using the ICF-CY-CHDS and analyzed using the Rasch model. RESULTS: The final ICF-CY-CHDS contained 22 categories; it exhibited a nonsignificant χ2 test result for the item-trait interaction (χ2 = 6736.37, p = 0.8660, Bonferroni-adjusted p = 0.0023). The average severity of children was less than the average difficulty of categories (-2.26 logit <0 logit). The weighted k of all the categories was 0.964 (p < 0.001), and the item separation index was 0.96. The area under the ROC curve of children with a diagnosis result of heart failure was 0.866 (95% CI: 0.801 ~0.931) with good sensitivity (0.875) and specificity (0.759). CONCLUSION: The ICF-CY-CHDS presents a preliminary practical direction during early cardiac rehabilitation after pediatric CHD surgery, and thus provides a basis and scope for clinical evaluation and intervention program formulation.
ABSTRACT
OBJECTIVE: Central obesity is considered to be a central component of metabolic syndrome. Waist circumference (WC) has been widely used as a simple indicator of central obesity. This study is aimed to evaluate the sensitivity of WC cut-off values for predicting metabolic risk factors in middle-aged Chinese. METHODS: The study involved 923 subjects aged 40-65 years. The metabolic risk factors were defined according to the Chinese Joint Committee for Developing Chinese Guidelines on Prevention and Treatment of Dyslipidemia in Adults. WC cut-off 85-90 cm and â90 cm were used as cut-off values of central pre-obesity and central obesity in males, respectively, while WC 80-85 cm and â85 cm were used as cut-off values of central pre-obesity and central obesity in females. RESULTS: First, WC values corresponding to body mass index (BMI) 24 kg/m2 and visceral fat area (VFA) 80 cm2 were 88.55 cm and 88.51 cm in males, and 81.46 cm and 82.51 cm in females respectively. Second, receiver operating characteristic curves showed that the optimal WC cut-off of value was 88.75 cm in males, higher than that in females (81.75 cm). Third, the subjects with higher WC values were more likely to have accumulating metabolic risk factors. The prevalence of metabolic risk factors increased linearly and significantly in relation to WC levels. CONCLUSION: WC cut-off values of central pre-/central obesity are optimal to predict multiple metabolic risk factors.
