| Sumario: | The objective of the present study was to evaluate the nutritional status of VA according to the biochemical marker (serum levels of retinol) and its association with anthropometric markers in individuals with class III obesity. Material and Methods: Data collection was conducted in the preoperatory of Gastric Bypass surgery in a private clinic in Rio de Janeiro. Serum levels of retinol were quantified by HPLC- UV method, with VAD cutoff of <1.05 μmol/L (WHO, 1996). The anthropometric evaluation included weight and height for calculation of the body mass index (BMI), waist circumference (WC), hip circumference (HC) and waist-hip circumference (WHC) according to the cutoffs recommended in literature. Results: One hundred and three patients of both genders with BMI >40 kg/m2 and with mean age of 36.4±11.7 years were evaluated. The prevalence of inadequate serum retinol (VAD) was 13.6%. There was negative and significant correlation between the serum levels of retinol and BMI. The correlation between serum retinol, WC and HC was negative and non significant but it presents clinical importance. Conclusion: The findings of the present study suggest that BMI, WC and HC, methods which are of easy application in clinical practice, of low cost and less invasive, may corroborate the diagnosis of VAD in individuals with class III obesity. |
