Abstract : Our study aimed to assess the nutritional status of Women of reproductive age in Morocco using body mass index (BMI) and an anthropometric-based prediction equation. A total of 2012 women of reproductive age (15–49 years), from the different regions of Morocco was included in this study. Socio-demographic, anthropometric measurements height and weight were collected. The mean of age, weight; height and BMI were 32.8 ± 9.3 years, 69.1 ± 14.4 kg, 159.7 ± 7.1 cm, and 27.1 ± 5.8 kg/m2, respectively. The mean of different body compartments (TBW, FFM, FM, FM%, FFMI and FMI) was 31.8 kg, 43.3 kg, 25.7 kg, 36.5%, 16.9 kg/m2 and 10.1 kg/m2 respectively. According to BMI, 32.4% of women were overweight and 27.5% were obese elsewhere according to FM%, 55.1% presented an excess of fat. However, 23.6% of women assumed to have a normal BMI were in excess of fat and 37% of women who were classified as overweight had no fat excess. In conclusion, the prevalence of excess of fat is higher in women of reproductive age in Morocco. The use of BMI seems to be unprecise in the case of normal-weight and overweight.
