Abstract:
Objective To supply a scientific basis for laying out a unified standard of reference value of Chinese newborn boys' hemoglobin. Methods After the reference values of 5169 Chinese healthy newborn boys' hemoglobin tested in 78 areas were collected, a research was made on the relationship between the reference value of Chinese newborn boys' hemoglobin and altitude by using curvilinear regression analysis. Results As the altitude gradually increased, the reference value of Chinese newborn boys' hemoglobin gradually increased by index law, with significant correlation (R=0.601, F=43.05, P= 0.0000). One curvilinear regression model was given out: =176.9e 0.00008662x?25.3. Conclusion If altitude of a particular area is known, the reference value of Chinese newborn boys' hemoglobin in this area can be established by using regression model. According to the correlation between Chinese newborn boys' hemoglobin and altitude, China can be divided into three regions: Qinghai-Tibet Region, Central Region, Eastern Region.
