Abstract:
OBJECTIVEThe level of blood hemoglobin and the anemia status of Chinese urban residents in 2010-2012 was analyzed.
METHODSAll the data in this study came from the China Nutrition and Health Survey in 2010-2012. By using multi-stage stratified sampling and population proportional stratified random sampling method, 74 276 residents aged above 6 from 34 metropolis and 41 middle-sized and small cities were included in this study. The concentration of blood hemoglobin was determined by cyanmethemoglobin method. Anemia was judged by the anemia standard recommended by WHO, combined with elevation correction standard. The level of blood hemoglobin, the prevalence of anemia and the 95%CI value were analyzed by using the complex sampling weighted processing, combined with the population figures released by the National Bureau of Statistics in 2009.
RESULTSIn 2010-2012, the level of blood hemoglobin of Chinese city population was(144.16 ± 0.78)g/L, (152.88 ± 0.94)g/L for male and(135.01 ± 0.71)g/L for female, while (145.65 ± 1.22)g/L for metropolis and (143.90 ± 0.89)g/L for small and medium-sized. The anemia prevalence of Chinese city population (pregnant women were not included) was 9.7%(95%CI: 9.4%-10.1%), 6.8%(95%CI: 6.4%-7.3%) for male and 12.8%(95%CI: 12.2%-13.4%) for female, while 8.5%(95% CI: 8.0%-9.0%) for metropolis and 10.0%(95%CI: 9.5%-10.4%) for small and medium-sized. The anemia prevalence of 18-44 women (15.4%, 95%CI: 14.3%-16.6%) was the highest among all the age-groups, and the average anemia prevalence of people more than 60 years-old (including) (12.5%, 95%CI: 11.8%-13.2%) was higher than the other age-groups.
CONCLUSIONThe anemia prevalence of Chinese city population in 2010-2012 was obviously decreased in comparison of 10 years ago, while, more attention and improvement measures should be take upon women at reproductive age and the elder people.
