Objective To investigate the associations between intake of the dietary iron and blood lipid in the soldiers of Armed Police Forces. Methods Dietary survey for 3 days by dietary weighing method was made and the total iron content, heme-iron and non heme-iron intakes were counted in 115 soldiers. Fasting total cholesterol (TC), triglycerides (TG), HDL cholesterol (HDL-C) and LDL cholesterol (LDL-C) were also measured. Logistic regression models and one-way ANOVA were used to assess associations and prevalence between the total iron content, heme-iron and non heme-iron intakes and dyslipidemia risks after adjusting for age, BMI and energy consumption. Results The average iron intake was higher than the Chinese DRIs value. The total dietary iron, heme iron and non-heme iron contents were 47.1mg, 26.5mg and 19.9mg, respectively. The total dietary iron content and heme-iron were positively associated with the blood total cholesterol (TC), triglycerides (TG), and low density lipoprotein cholesterol (LDL-C) (P＜0.05). With increasing dietary iron content and heme-iron, dyslipidemia risks were significantly increased.Conclusion Dietary iron from animal foods may have a bad effect on the blood lipid levels.
