The visceral adiposity index and lipid accumulation product as predictors of cardiovascular events in normal weight subjects. (December 2022) - Darroudi, Susan
Summary: Introduction: Visceral adipose tissue (VAT) has an important role in the incidence of cardiovascular disease (CVD) than obesity by itself. The visceral adiposity index (VAI) and lipid accumulation product (LAP) are surrogate indices for measuring VAT. The aimed of this study was to investigate the association of these markers with cardiovascular events among populations with different BMI category in Mashhad, northeast of Iran. Method: The present study comprised a prospective cohort of 9685 men and women (35–65 years) who were recruited from MASHAD study. BMI category was defined as normal weight (BMI <25), over weight (25 ≤ BMI<30) and obese (BMI≥30). Demographic, laboratory evaluations, anthropometric and metabolic parameters were performed. Logistic and Cox regression analyses were used to determine the association and risk of cardiovascular events with VAT and LAP. Results: The mean VAI and LAP in CVD patients were significantly higher than in healthy ones in all 3 groups. In terms of CVD event prediction, VAI and LAP had significant association with the incidence of CVD in the second (RR (95% CI): 2.132 (1.047–4.342) and 2.701 (1.397–5.222), respectively) and third tertiles (RR (95% CI): 2.541 (1.163–5.556) and 2.720 (1.159–6.386), respectively) in the normal group, but this association was only found in the third tertiles (RR (95% CI): 2.448 (1.205–4.971) and 2.376 (1.086–5.199), respectively) in the overweight group. The result couldn't find this association for the obese group. Conclusion: In this study, we found that there was a significant association between LAP and VAI and cardiovascular events in normal weight and over-weight groups; however, no significant relationship was found in the obese group.
