ABSTRACT
Objective To evaluate the malnutrition status and analyze the changing trends of nutritional status among primary and middle school students in poor rural areas of Chongqing from 2013 to 2019, and to provide scientific bases for formulating measures to improve students' nutrition status. Methods In 12 poor rural areas in Chongqing, a random sampling was adopted. At least 10% of elementary and middle schools were randomly selected in each area each year. At least 40 students were sampled in each grade to measure their height and weight. The nutritional status of the students was evaluated and the changing trend of nutritional status in the five years from 2013 to 2019 was analyzed. Results From 2013 to 2019, the prevalence rate of malnutrition showed a downward trend. The prevalence rate of malnutrition of boys was higher than that of girls. The prevalence rate of growth retardation decreased more significantly than that of emaciation. Conclusion The status of malnutrition among students in poor areas of Chongqing had been improved, but had not been eliminated yet. Further attention should be paid to the changes of students' nutritional status and timely measures should be taken to improve the students' nutritional and health status.
ABSTRACT
Objective To investigate the association between milk intake at breakfast and nutritional status of students attending the Nutrition Improvement Program for Rural Compulsory Education Students (NIPRCES) in 2016,and to provide basic data for improving the nutritional status of the poor rural pupils.Methods Using the multi-stage stratified random cluster sampling method,22 315 students from grade three to nine from primary and junior high schools were randomly selected from the 50 key counties under the monitor programs,in 22 provinces of NNIPRCS.Questionnaire was used.Among all the students,with equal number of genders,morning fasting height and weight were measured by trained investigators.Status of nutrition was classified as malnutrition,normal,overweight/obesity,by age-specific height and BMI.Multivariate linear and logistic regression methods were used to analyze the relationship between milk consumption and the status of nutrition of the students.Results Only 31.4％ of the students that were on the monitoring programs would drink milk at breakfast.Proportions of milk intake at breakfast were higher in students from the western regions,in lower grades and in girls (P＜0.05).The proportions of malnutrition and overweight/obesity were 11.0％ and 10.0％ respectively.After controlling factors as gender,age,ethnicity,region of residency and types of parental employment,students who drank milk at breakfast showed an average height of 0.4 cm taller than those who did not drink milk (P=0.001).However,no significant relationships were noticed between milk intake at breakfast and weight,malnutrition or overweight/obesity.Conclusion Milk intake at breakfast seemed associated with the height of the students under study,suggesting that this program can be promoted,especially in students from the poor rural areas.

ABSTRACT
Objective@#To describe the situation and identify factors associated with malnutrition among infants and young children aged 6-23 months in poor rural areas in Hunan Province in 2015.@*Methods@#8 735 rural infants and young children aged 6-23 months in 30 poor counties of Wuling Mountains and Luoxiao Mountains in Hu'nan province were selected by township-level probability proportional to size sampling (PPS) in August 2015, infants' body length and weight were measured, and questionnaires were used to collect infants' information on personal and family, and feeding status in the past 24 h. The prevalence of stunting, underweight and wasting were calculated according to the Growth Standards of Child Aged Under 7 in China which was established in 2009 by Community Health Department of National Health and Family Planning Commission, China (formerly Chinese MOH), and the prevalence of malnutrition was calculated according to the classification of children with anthropometric failure. Multi non-conditional logistic regression model were used to analyze factors associated with malnutrition among infants and young children aged 6-23 months.@*Results@#The prevalence of malnutrition among infants and young children aged 6-23 months was 13.7% (1 198/8 735), the prevalence of stunting, underweight and wasting among infants and young children aged 6-23 months were 4.8% (419/8 735), 9.7% (849/8 735) and 6.1% (531/8 735) respectively. Compared with male group, the OR value of malnutrition for the female group was 1.16; Compared with Han ethnic group, the OR value of malnutrition for the Miao and Tujia ethnic group were 0.83 and 0.66, respectively; Compared with mother with an education level of primary school or below, the OR value of malnutrition for the mother with junior high school, senior high school and university or above education were 0.65, 0.61 and 0.56, respectively; Compared with father with an education level of primary school or below, the OR value of malnutrition for the father with senior high school and university or above education were 0.71 and 0.61 respectively; Compared with normal birth weight group, the OR value of malnutrition for the low birth weight group and high birth weight group were 2.85 and 0.27 respectively; Compared with normal delivery group, the OR value of malnutrition for the premature delivery group was 1.37; all P values<0.05.@*Conclusion@#The prevalence of malnutrition among infants and young children aged 6-23 months in poor rural areas in Hunan province in 2015 was high; Infants and young children who were female, Han ethnic, parents with low education, low birth weight and premature delivery had higher risk of malnutrition.
ABSTRACT
Objective To analyze the status of anemia among children under 5 years of age in the economically less developed rural areas from 6 western provinces of China in 2009. Methods 8141 study subjects were from the program-‘Study on Appropriate Technology of Children Under-nutrition Improvement in Poor Rural Areas'. Results In 2009, the prevalence of anemia among children under 5 years of age in the above said rural areas from 6 western provinces was 24.1％. The prevalence of anemia among male children was much higher than that among female children. The peak of anemia prevalence( 38.5％ ) was among children of 6-11 months. The prevalence of anemia decreased along with the increase of age. Conclusion Results from the study demonstrated that anemia among the preschool children was a public health problem in poor rural areas of western China, Improving the knowledge on reasonable feeding seemed a better way for the prevention and control of anemia plus providing complementary nutrients sprinkle to the affected children.
