Hemoglobin levels and anemia prevalence among Chinese students aged 10-11:evidence from the 2018 China education panel study primary school cohort
Objective To analyze the hemoglobin level and anemia prevalence in Chinese 10-11 years old children and to explore possible socio-economic factors.Methods Grade 4 students data from China education panel survey(CEPS)was used and there are 17 695 students with hemoglobin data.The anemia status was diagnosed by using hemoglobin of fingertip blood and adjusted with altitude of each school.All socio-economic factors were collected from questionnaire survey.Multiple logistic regression a-nalysis model was used to analyze the influencing factors of anemia prevalence.Results The mean concentrations of hemoglobin were(130.61±11.32)g/L and(131.88±11.85)g/L,and the anemia prevalence was 6.78％and 6.28％respectively in 10 and 11 years old students.The mean concentrations of hemoglobin were(131.52±11.62)g/L and(130.96±11.60)g/L,and the anemia prevalence was 6.41％and 6.64％respectively in male and female students.The students with urban Hukou had higher mean concentrations of hemoglobin than that of students with rural Hukou,the mean concentrations of hemoglobin were(132.02±11.32)g/L and(130.70±11.78)g/L,and the anemia prevalence was 5.04％and 7.59％respectively.Multivariate logistic regression analysis showed that primary school students with rural household registration had a higher risk of anemia[OR(95％CI)=1.26(1.09～1.46),P=0.002],while that of 11-year-old students[OR(95％CI)=0.85(0.75～0.96),P=0.010],Primary school students with medium or higher family economic status and parents with the highest education in high school or above had a lower risk of anemia(all OR＜1.00,P＜0.05).Conclusions The anemia is still a public health issue worthy of attention in 10 and 11 years old students and the anemia prevalence is different in different socio-economic students.The prevention and control of anemia should be focused on fragile population distribution and more targeted strategies are needed.
