Pontos de corte da circunferência do punho para determinação dos níveis de excesso de peso e predição do risco cardiometabólico em adultos

Abstract

Elevated wrist circumference may indicate overweight and cardiometabolic risk. Based on this evidence, the present thesis aims to identify the cutoff points of wrist circumference (PC) for determining overweight levels and predicting cardiometabolic risk in adults. A cross-sectional study was conducted with adults aged 20 to 59 years treated at the outpatient clinic of the HU/UFS-EBSERH. Demographic, anthropometric, biochemical and blood pressure (BP) data were collected from the adults in the study. Cardiometabolic risk was assessed according to the criteria of the ERG global risk score and Framingham score. For the descriptive analysis, the medians, means, standard deviations and frequencies of anthropometric, demographic, biochemical and blood pressure variables were calculated. The Mann-Whitney test was used to compare data between groups of adults by gender and age group. Spearman's correlation coefficient and multiple regression analysis were used to evaluate the association between PC and anthropometric, biochemical and BP variables. The predictive validity of PC in the identification of overweight levels and cardiometabolic risk was analyzed using the ROC curve. The sample consisted of 1487 adults aged 20 to 59 years, 55.7% of whom were female. PC was positively correlated with other adiposity indicators such as waist circumference and Body Mass Index. PC was the anthropometric indicator that was most significantly associated with cardiometabolic risk factors. The PC cutoff points determined by the study to identify overweight and obesity were categorized by sex and age group, male gender; 20 to 40 years and > 40 years were respectively, overweight 17.1 cm; 17.3 cm ; obesity 17.9 cm; 17.5 cm and for females aged 20 to 40 years and > 40 years were overweight 15.6 cm; 15.4 cm, and for obesity 16.1 cm; 16 cm. The PC cutoff points for predicting cardiometabolic risk were as follows: female; 20 to 40 years and > 40 years, respectively 16.4 cm and 16.6 cm for risk (ERG and Framingham) and in males; 20 to 40 years and > 40 years, respectively 16.9 cm and 17 cm Framingham and 17.2 cm and 17 cm for ERG. Wrist Circumference showed a significant correlation with other adiposity indicators and can be used to identify overweight adults and predict cardiometabolic risk.
