Abstract:
ObjectiveTo understand the physical development level of 3-7 years old children in Zhag′yab， and to provide reference for local health decision-making. MethodsA cross-sectional study was conducted between June 2021 and July 2021， with a sample of 1 247 Tibetan children aged 3-7 years from kindergartens in 13 districts of Zhag′yab. Their height and weight were measured and the hemoglobin was detected by a unified method. Standard statistical method was adopted （Z-score method）. Z-scores of length /height-for-age （HAZ）， Z-scores of weight-for-age （WAZ）， Z-scores of body mass index （BMI）-for-age （BAZ） and Z-scores of weight-for-height （WHZ） were calculated by WHO Anthro v3.2.2 and WHO Anthro Plus. The nutritional status of children was evaluated according to WHO diagnostic criteria for malnutrition and anemia. ResultsThe average WAZ and HAZ of children aged 3 to 7 in Zhag′yab were lower than the WHO standards，except for the WAZ of 4-year old， the differences were statistically significant （P<0.05）. The overall detection rate of malnutrition was 25.7%， stunting， underweight， wasting， overweight， obesity and anemia were 11.6%， 11.8%， 10.8%， 3.3%， 1.8% and 29.3%， respectively. The detection rates of all indicators in boys were higher than those in girls， and the differences were not statistically significant （P>0.05）. The overweight rate and obesity rate of rural children were lower than those of urban children， and the other detection rates were higher than those of urban children. The differences of underweight rate， obesity rate and anemia rate were statistically significant between urban and rural children （P<0.05）. Among the detection rates of all indicators in different age groups， there were statistically significant differences in the overweight rate and the anemia rate （P<0.05）. The overweight rate of children aged 4 and the anemia rate of children aged 5 were the highest. ConclusionsThe physical development of children aged 3 to 7 in Zhag′yab is poor， and the prevalence of malnutrition and anemia is high. Underweight and anemia are more serious in rural children， and the overweight and obesity problem of urban children is emerging. More attention should be paid to promote their nutritional status. The prevention and intervention of children’s malnutrition should be strengthened in Zhag′yab.
