Study Purpose
The purpose of this study was to determine the effects of patient age, gender, parity, education level, income, and ethnicity on sTfR levels in serum. Both male and female children were included in the study, however, only non-pregnant women of childbearing age (15-49) were included.
Summary of Findings:
Serum from children (1-5 y) had significantly higher levels of sTfR than serum from women of childbearing age (15-49 y). Levels of sTfR were higher in the serum from 1-2 year olds than 3-5 year olds, boys than girls, and non-hispanic blacks than other ethnicities. Specimens from 20-49 year old women had lower levels of sTfR than specimens from 15-19 year old women after adjusting for socio-demographic variables. Serum from non-hispanic black women had the highest levels of sTfR while serum from non-hispanic white women had the lowest levels of sTfR. Serum from women who had given birth 2 or more times contained higher levels of sTfR than serum from women who had never given birth. After adjustment for socio-demographic variables, neither patient education level, nor family income had effects on sTfR levels.
