Background
Body mass index, an estimate of body fat percentage, has been previously shown to be associated with metabolic disorders. However, there is little data on the associations between a body shape index (ABSI) or modified body adiposity index (MBAI), which provide valuable definitions of body fat, with serum biochemical parameter levels. Therefore, this study was conducted to find either ABSI or MBAI associations with serum biochemical parameter levels in bariatric surgery candidates.
Methods
This cross-sectional study was conducted on 776 bariatric surgery candidates (age range 18–69 years) between November 2010 and September 2017. Demographic data, anthropometric indices, biochemical parameters, and body composition analysis data were drawn from the National Obesity Surgery Database, Iran. ABSI and MBAI were calculated using related equations. A stepwise multivariate linear regression was used to evaluate whether ABSI or MBAI was associated with each serum biochemical parameter.
Results
ABSI, age, and multivitamin/mineral supplementation (MVMS) were independently associated with serum vitamin D (β = 24.374, SE 10.756, P value 0.026; β = 0.022, SE 0.007, P value 0.002; β = 0.639, SE 0.235, P value 0.008). However, a negative association was observed between MBAI and vitamin D (β = − 0.037, SE 0.016, P value 0.025) in a model adjusted for age and MVMS. Additionally, MBAI and age showed a significant positive association with serum HDL-c (β = 0.185, SE 0.085, P value 0.028; β = 0.171, SE 0.033, P value < 0.001), although there was a negative association between male sex and HDL-c (β = − 4.004, SE 0.891, P value < 0.001).
Conclusion
ABSI and MBAI may be appropriate indices in predicting serum vitamin D and HDL-c levels.
