The prevalence of Diabetes Mellitus (DM) in the Caribbean is high. BMI has been criticized as a measure for predicting T2 DM development because it does not discern between fat mass and muscle mass, nor does it reect an individual's fat distribution. The primary objective of the study was to determine the association between Indices using height, waist, hip, thigh, arm, and wrist circumference (cm) with development of T2 DM by comparing it to existing markers in test subjects and assessing their feasibility as predictive indicators for the development of Type 2 DM. In a cross-sectional study, a total of 331 subjects were involved in the study utilizing health centers and health camps in St Kitts (West Indies). Height was measured using Stadiometer, Weight using a calibrated digital weighing scale. Waist, hip, thigh, arm, and wrist circumference (cm) was measured using calibrated tape. ABI (Arav Body Index) is measured using a ratio of Waist and Combined Thigh & Height, Thigh to waist ratio (TWR) and Wrist to arm ratio (WAR) was compared to WHtR, WHR and BMI. ABI had the highest AUROC value among the ve adiposity indices (0.803, 95% condence interval [CI], 0.755 to 0.851; 0.785, 95% CI, 0.735 to 0.835 for WHtR; WHtR (0.785), WTR (0.672), WAR (0.652) and BMI (0.626). The cutoff values for ABI were 0.43. Among subjects with ABI less than 0.42, 83.8% (129) did not have type 2 DM and ABI more than 0.48, 90.2 % (51) had T2 DM. Hence, higher ABI strongly correlates with development of T2 DM. We conclude that ABI could be a more reliable tool for identifying individuals at risk of developing type 2 DM. This will help at-risk individuals to take preventive measures like lifestyle modication.
Introduction: The prevalence of hypertension in the Caribbean is high [26% in Saint (St.) Kitts]. It contributes to 51% of deaths secondary to ischemic heart disease and hence being a leading cause of death in the Caribbean region. Aim: To determine the association between Indices using height, waist, hip, thigh, arm, and wrist circumference (cm) with development of hypertension and to compare existing markers in test subjects and assessing their feasibility as predictive indicators for the development of hypertension. Materials and Methods: In the present cross-sectional study, a total of 635 subjects were involved in the study which included health centres and health camps in St. Kitts (West Indies). Study was conducted from December 2019 to November 2020. Height to Waist Ratio (HtWR), Arav Body Index (ABI), Waist to Thigh Ratio (WTR) and Wrist to Arm Ratio (WAR) was compared to common existing markers such as Waist to Height Ratio (WHtR), Waist to Hip Ratio (WHR) and Body Mass Index (BMI). Statistical analysis was done using using IBM Statistical Package for the Social Sciences (SPSS) version 23.0. Results: A total of 635 participants were included with most of the participants (n=540) between age group of 40 to 70 years, 35.4% (n=225) of participants were males and 64.6% (n=410) were females. In the present study, 47.92% (n=304) were non hypertensive and 52.1% (n=331) were hypertensive. In males, Area Under Receiver Operating Curve (AUROC) of HtWR (0.690) and Inverse ABI (0.632) was superior as compared to other anthropometric markers for predicting the development of hypertension and Waist to Thigh Ratio (WTR) (0.687) was superior in females. Among females recommended cut-off values for WTR is 1.6 and among males for HtWR and Inverse ABI were 2.3 and 2.84, respectively. Conclusion: Height to waist ratio and inverse ABI were more reliable markers in males for predicting the development of hypertension whereas, WTR being more reliable in females in population of St. Kitts. This will help at risk individuals to take preventive measures like lifestyle modification.
