Vitamin A (VA) has a negative association with body mass index (BMI) since it is involved in the regulation of body adiposity via nuclear receptors. However, few studies have investigated the relationship between VA nutritional status and the way body adipose is stored, which is the aim of this cross-sectional analytical study with Brazilian adult women in different BMI classes with the intake of VA recommended. VA nutritional status was assessed by serum retinol and ß-carotene measurements, dietary intake, and diagnosis of night blindness (NB). Results: 268 women with mean age of 38.00±5.80 years. According to the BMI, 30.97% were normal weight, 14.18% overweight, 25.37% class I obesity, 14.55% class II, and 14.93% class III.The prevalence of low serum of ß-carotene, retinol, and presence of NB in the total sample was 73.5%, 45.9%, and 20.1%, respectively. A total of 86.7% of normal weight women had inadequate visceral adiposity index (VAI) and 41.0% had inadequate body adiposity index (BAI).VAI was the body adiposity marker with the highest association with low serum retinol and b-carotene concentrations (P<.001). There was presence of NB in 100% of cases of inadequacy of BAI (P<.001). High visceral and body adiposity were associated with compromised VA nutritional status regardless of BMI and the recommended intake of VA. Additional measures to assess body adiposity, and especially its distribution, may collaborate in clinical practice to identify women at risk of compromising their VA nutritional status even when they are classified as normal weight according to their BMI.
