Effects of egg and milk supplementation on growth and development among children in poor rural area / 中华预防医学杂志

<p><b>OBJECTIVE</b>To evaluate the effects of egg and milk supplementation on growth and development and body composition among children in poor rural area in Tianyang County of Guangxi province.</p><p><b>METHODS</b>Total four schools were randomly selected from four towns in Tianyang County of Guangxi province as intervention group in April, 2013. The intervention measures included that these students were given salty egg (net weight: 50 g) and ultra-high-temperature-sterilization school milk (net weight: 200 g) every school day and these schools were equipped with standard kitchens. Another four schools of familiar socio-economic level, teaching quality and size from the same town were randomly chosen as control group and none of the intervention measures were implemented. About 25 students were randomly selected and stratified by grades from grade one to grade five. The height, weight, and body composition of all students were measured in April, 2013 and one year after the intervention. A total of 978 students were measured at baseline from age 6 to 13, 552 students as intervention group and 426 as control group. t-test was used to compare the differences between groups and multivariate unconditional logistic regression was used to analyze the factors of malnutrition.</p><p><b>RESULTS</b>After one year intervention, 892 students were measured randomly, with 515 students in intervention group and 377 in control one. The average weight of boys in intervention group increased (3.6 ± 1.7) kg compared with baseline. It was significantly higher than that of control group ((2.9 ± 1.5) kg) (t = 4.40, P < 0.001). The boy's lean body mass of intervention group increased (2.6 ± 1.4) kg, higher than the control group ((2.0 ± 1.2) kg) (t = 3.95, P < 0.001). The decrease of malnutrition rate of intervention schools (11.8%) was significantly higher than that of the control schools (4.7%, χ² = 16.90, P < 0.001), and the odds ratio was 0.37 (95% CI: 0.23-0.59). The risk difference of overweight and obesity was not statistically significant between the two groups (OR = 1.68, 95% CI: 0.57-4.94).</p><p><b>CONCLUSION</b>After supplementing milk and egg, the nutritional status of the poor rural pupils was improved.</p>
