ABSTRACT
Anemia, iron deficiency (ID), and iron deficiency anemia (IDA) are common disorders. This study was undertaken to determine the prevalence of anemia, ID, and IDA in Korean females. We examined the associations between IDA, heavy metals in blood, vitamin D level and nutritional intakes. The study was performed using on data collected from 10,169 women (aged ≥ 10 yr), including 1,232 with anemia, 2,030 with ID, and 690 with IDA during the fifth Korea National Health and Nutrition Examination Survey (KNHANES V; 2010-2012). Prevalence and 95% confidence intervals were calculated, and path analysis was performed to identify a multivariate regression model incorporating IDA, heavy metals in blood, vitamin D level, and nutritional intakes. The overall prevalence of anemia, ID and IDA was 12.4%, 23.11%, and 7.7%, respectively. ID and IDA were more prevalent among adolescents (aged 15-18 yr; 36.5% for ID; 10.7% for IDA) and women aged 19-49 yr (32.7% for ID; 11.3% for IDA). The proposed path model showed that IDA was associated with an elevated cadmium level after adjusting for age and body mass index (ß=0.46, P<0.001). Vitamin D levels were found to affect IDA negatively (ß=-0.002, P<0.001). This study shows that the prevalence of anemia, ID, and IDA are relatively high in late adolescents and women of reproductive age. Path analysis showed that depressed vitamin D levels increase the risk of IDA, and that IDA increases cadmium concentrations in blood. Our findings indicate that systematic health surveillance systems including educational campaigns and well-balanced nutrition are needed to control anemia, ID, and IDA.
