Abstract: Nutritional assessment of women at reproductive age should identify factors that may affect fertility, periconceptional health and pregnancy outcome. The aim of this study was determination of anthropometric factors, calorie and nutrients intake as well as food habit. In a descriptive cross- sectional study, 1906 females (939 urban and 967 rural) at reproductive age were selected by multi stage sampling method. Variable including age, anthropometric factors (e.g., height, weight), calorie and nutrients intake as well as the food habit were measured for each case in 2005. Height and weight were obtained using a portable digital scale and a portable digital Stadiometer following standard technique. Body Mass Index (BMI, in kg m ²) was calculated from the women height and weight. In order to determine dietary intake, information of 24 h dietary food recall was recorded for three successive days. The prevalence of food frequency among women was evaluated using specific questionnaire. Statistical comparison of means among groups was performed with ANOVA and t-test. Weight and height of urban women were more than rural women, significantly (p < 0.05). With increase of age, BMI and obesity were increased, significantly (p < 0.05) and observed in urban women up 35 years old. The mean of daily iron and protein intakes of women were adequate. However the mean of fiber, folate, vitamins B2 and B6, calcium, zinc, selenium and calorie intake were less than dietary reference intakes (p< 0.05). Intake of some food groups such as bread, dairy and milk were adequate, but intake of unsaturated fat and fish were fewer in dietary women. In Ardebil province 13.7, 41.45, 29.4 and 15.3% of women at reproductive age had underweight, normal, overweight obese, respectively.
