目的通过对宝安区小儿发锌、钙、铅元素水平的测定与分析,探讨预防和治疗措施。方法采用原予吸收分光光度计测定237名0.5~12岁小儿的头发标本。结果锌、钙、铅三元素含量与年龄有关,其中发钙含量有性别差异。四组中铅高(73.42%)占第一位,其次为钙缺乏(54.85%)和锌缺乏(8.43%)。有害元素发铅阳性率依次为幼儿、学龄前、婴儿和学龄组;但学龄组发铅较高率显著性高于其他组(X^2〉11.94,P〈0.01)。幼儿组钙缺乏率最高,且钙缺乏率有随年龄降低的趋势。锌缺乏率无组问差异,但有随年龄增高的趋势。结论高铅和钙营养不足是本地区小儿最主要的健康问题。幼儿和学龄前儿童是防治铅高和钙缺乏的重点对象,应采取均衡营养、科学饮食和合理补充等综合防治措施以降低微量元素缺乏或过多给儿童生长发育带来的危害。 相似文献

In this study the hair zinc levels of 115 healthy subjects, 50 girls and 65 boys, between the age groups 0 to 15 years were determined by using atomic absorption spectrophotometry. The hair zinc levels obtained generally agree with those reported in the literature. The hair zinc levels of the subjects were studied as a function of age, sex and color of hair. It was found that the levels of hair zinc increased as a function of age, whereas no statistically significant differences with respect to sex and color of hair were observed. In a protein-calorie malnourished group of 11 girls and six boys between the ages 0 to 3 years, it was found that the hair zinc levels were significantly higher than a group of healthy subjects of the same age range. In a protein-calorie malnourished group of seven subjects no correlation was found between hair zinc and serum levels. 相似文献

Background
While annual influenza vaccination is recommended by the CDC for children 6 months and older, vaccination rates remain suboptimal. For healthy, US children 2 years of age and older, influenza vaccine is available as an intramuscular injection (TIV) or an intranasal spray (LAIV), respectively. Little is known about children's experiences and preferences for influenza vaccine attributes.Objective
To examine preferences for influenza vaccine attributes and their relative importance among children.Methods
A quantitative web-survey was administered to children aged 8-12 years sampled from a standing online panel representative of the US population. Children were stratified by age, gender and parent's influenza vaccination behavior. The survey included questions to ascertain children's preferences for influenza vaccine attributes, including efficacy, chance of common side effects, and mode of administration. It included conjoint (trade-off) questions in which children traded-off different attributes in their choice between two influenza vaccines with differing features. We also surveyed children's comprehension of and ability to complete the conjoint questions.Results
544 children completed the survey (response rate 37%). Children most frequently selected efficacy as the most important vaccine attribute followed by mode of administration (45% and 31%, respectively). When asked for their preference to receive influenza vaccine as a “shot” or a “nose spray”, the majority (69%) preferred the nose spray. An evaluation of children's ability to complete the conjoint survey demonstrated that 85% of the sample was able to complete the conjoint tasks. Analysis of the conjoint responses demonstrated that mode of administration and efficacy had the greatest impact on preferences, with a relative importance of 40.5% and 30.6%, respectively. In a direct comparison of vaccine profiles representing the efficacy, side effects, and other characteristics of LAIV and TIV, 79% of children preferred the LAIV-like profile.Conclusion
Children in the sample had consistent opinions regarding influenza vaccine attributes and consider vaccine efficacy and mode of administration to be important. Children can be informed participants in influenza prevention and can be included in discussions regarding influenza vaccination. 相似文献14.
The calcium, magnesium, zinc, iron, and copper content found in scalp hair of 40 children with mental retardation were compared with 37 healthy normal children who were between the ages of 4 and 14 yr. The hair of children with mental retardation showed significantly lower levels of iron, copper, and magnesium (p less than .001) and higher levels of calcium (p less than .001). The zinc content did not differ between the two groups. The differences in levels of hair trace elements between normal children and those with mental retardation could be of particular interest in the investigation of the cause of mental retardation among children. 相似文献

The results of two methods for the estimation of calcium and phosphorus in daily rations of children aged up to 1 year were compared by simple statistical tests. Ca and P contents were determined by the analytical method; moreover, the theoretical Ca and P contents were calculated from the bills of fare menus and food composition tables. The analytical procedure was accepted as reference method. Ca and P contents determined by the analytical method accounted, on the average, for ca. 90% of those obtained by the calculation method. The coefficients of correlation between the results obtained by both methods (x and y) amounted to: rCa = 0.456 and rP = 0.786. There were significant differences between Ca and P contents obtained by both methods at significance level alpha = 0.05. 相似文献
