Abstract: Objective To analyze the change and trend of prevalence of congenital hypothyroidism(CH), and to provide scientific support for the establishment of reasonable strategy and measure for the prevention of CH. Method The information from neonatal screening program during 1994-2011 in Beijing were made by descriptive analysis and statistical inference. Results The prevalence rate of CH showed upward trend in Beijing during 18 years, the average prevalence rate was 31.80/10⁵.In 2003 the laboratory method of CH had been changed from RIA to time-resolved fluorescence immunoassay.which maybe led to the upward trend of the prevalence rate of CH in Beijing. Conclusion The prevalence rate of CH shows upward trend in Beijing during 1994-2011.
