| Objective This study aims to evaluate real level of weight,6inorganic elements (zinc,iron,calcium,magnesium,copper and lead) among0-3years old young children in a community and analysis the relationship between the level of weight, inorganic elements so as to provide basis for health of children.Subjects The children were outpatients of children health care clinic of a community health centre from October2009to April2011, who is health without rhachitis, infection, anemia, diarrhea, serious rickets disease, endocrine disease.There were369boys and275girls, aged from2to36months old (average10.8).Methods Weight was assessed by WHO Child Growth Standards(2006) and measured by the method of Practice of Pediatrics.6inorganic elements were measured by method of atomic absorption spectrometry and postive anode electrolysis. T-test, chi-square criterion, covariance analysis and correlation analysis in analysis of variable data were conducted with SPSS17.0software.Results The overall weight level of0to36-month-old children in the community were higher than the mean level of the WHO reference value. The overweight rate and obesity rate were20.7%and8.1%, overweight-obese rate was2.5in all ages, the highest obesity prevalence rates of all ages was0to6months old (overweight27.5%, obesity12.7%), obese boys.The rate of overweight and obesity in boys was higher than girls (boys:33.1%, girls:22.5%). Overweight and obesity prevalence were statistically significant between different gender and age groups(P<0.05). There were statistically significant differences in inorganic elements in different age groups:the boys’ blood lead levels significantly higher than girls’in0-6months (t=10.465,P=0.001); serum calcium level of girls were significantly greater than boys of7-12month group(t=5.749,P=0.017);13～36-month-old boy blood copper, lead values significantly higher than girls’(t=10.306,P=0.002). The lack of inorganic elements:calcium deficiency (29.3%), followed by followed by zinc deficiency (17.4%), magnesium deficiency (13.5%), iron deficiency (5.1%).Children of the community were without blood copper deficiency, high-lead rate was5.9%. Blood iron deficiency rate of all age groups, the difference was statistically significant (x2=6.472, P=0.039). Blood of boy and girl both contained lead elements, but the boy’s blood lead was significantly higher than girls (x2=4.432, P=003).0～36-month-old children’s serum zinc iron joint lack of rate of6.6%, which is most common in the0to6months of age group, followed by decrease with age. In addition to the blood zinc and copper, calcium and copper were outside, the other blood trace elements were significantly correlated (P<0.01). The weight and WAZ of7to12-month-old children with blood zinc, iron, calcium deficient group and normal trace elements were significantly different(P<0.05). The weight and WAZ of13to36-month-old boy with blood zinc deficiency group normal group were significantly different(t=2.538,P=0.013). Boy weight and Z value of0～6and7～12months with high blood lead group and normal blood lead level were significantly different (t=-2.247,P=0.026).Conclusion Obesity and overweight was more prominent in the community. Children’s6inorganic elments in the community were average in the middle or secondary level in the normal range, blood lead level was lower than the level of a national survey. There were relationship between blood zinc, iron deficiency and children weight. |
