Abstract

Background: The study aimed to investigate the association of Body Roundness Index (BRI), A Body Shape Index (ABSI), and Conicity Index with nutritional status and cardiovascular risk factors in South African rural young adults.

Methods: The study included a total of 624 young adults aged 21-30 years from the Ellisras rural area. Anthropometric indices, blood pressure (BP), and biochemical measurements were measured.

Results: BRI was significantly correlated with insulin (0.252 males, females 0.255), homeostatic model assessment (HOMA)-β (0.250 males, females 0.245), and TG (0.310 males, females 0.216). Conicity Index was significantly associated with pulse rate (PR) (β 0.099, 95% confidence interval (CI) 0.017, 0.143, < 0.013; β 0.081, 95% CI 0.000 0.130, < 0.048), insulin (β 0.149, 95% CI 0.286 0.908, < 0.001; β 0.110, 95% CI 0.123 0.757, < 0.007). Conicity Index is associated with insulin resistance (IR) (odds ratio (OR) 7.761, 95% CI 5.783 96.442, < 0.001; OR 4.646, 95% CI 2.792 74.331, < 0.007), underweight (OR 0.023, 95% CI 0.251 0.433, < 0.001; OR 0.031, 95% CI 0.411 0.612, < 0.001), and obesity (OR 1.058, 95% CI 271.5 4.119, < 0.001; OR 1.271, 95% CI 0.672 1.099, < 0.001).

Conclusion: Conicity Index was positively associated with insulin resistance, hypertension and dyslipidaemia. Further investigation of these indices and their association with nutritional status and cardiovascular diseases (CVDs) could assist in efforts to prevent CVD in the rural South African population.
