title: Association of body mass index with hemoglobin concentration and iron parameters in Iranian population.
abstract: Background. Studies have reported that obesity has an adverse effect on iron metabolism. Obesity is characterized by chronic, low-grade, systemic inflammation and anemia of chronic disease with elevated serum ferritin and decreased level of serum iron, transferrin saturation, and hemoglobin. Therefore, we examined the association of body mass index with hemoglobin concentration and iron parameters in this study. Methods. This cross-sectional study was conducted in Yazd to assess the relation of body mass index with hemoglobin and iron parameters among 406 adult patients 18-65 years old. Diabetes and conditions that could influence body iron stores were excluded. Results. There is no difference in hemoglobin concentrations, MCV, serum iron, TIBC, transferrin saturation index, and ferritin between normal weight, overweight, and obese persons. Conclusion. Nutritional status of persons and intake of high iron foods by obese persons should be considered. Also, other inflammatory markers should be evaluated in the future studies.
