The Preliminary Study On The Reference Intervals Of Blood Calcium Contents In The Healthy Population Aged0to17in8Provinces Of China

Objectives:1. To measured eight provinces population aged0to17peripheral blood calcium levels;2. analysis of eight provinces population aged0to17peripheral blood calcium levels;3. according to the Health statistical principles, explore aged0to17years old healthy people of different ages peripheral blood calcium reference intervals;4. according to the population aged0to17element of peripheral blood calcium levels, determine the nutritional status of young people for nutrition provide scientific intervention.Methods:Adoption to entire cluster sampling method, select2006a2009eight provinces in the country. The city a total of16maternity and child care health examination population aged0to17years were101,600cases of the crowd as the object of study, the inclusion criteria:no obvious discomfort complaints, no acute or chronic disease, normal physical development, and physical examination showed no significant abnormalities. Using BH5100multi-channel detection by flame atomic absorption spectrometry in whole blood calcium levels,0years to17years and the overall level of the population of eight provinces calcium content and calcium content of all ages were analyzed, based on statistical principles to determine the value of peripheral blood calcium element reference interval using the normal distribution method.Results:1.101600cases mean serum calcium1.76mmol/L, standard deviation of0.209mmol/L, serum calcium values Sichuan highest,1.88mmol/L, Zhejiang lowest1.55mmol/L.2. on the whole, the provinces population aged0to17, but each of calcium inverse relationship with age, is decreased with increasing age, and the age of each element in the peripheral blood calcium levels significantly.3. reference values from eight provinces calcium distribution, increase with age, blood Lower calcium decreased from1.54mmol/L decreased to1.16mmol/L, ceiling from2.24mmol/L decreased to1.86mmol/L. The normal distribution method and the percentile method to establish 95%calcium reference range exactly.Conclusions:This study initially established Chinese population aged0to17years peripheral blood calcium range of reference values for determine the unified calcium reference values to provide a scientific basis, and Simultaneously and separately established and developed a range of reference values in eight provinces in the population aged0to17years old in the peripheral blood of calcium, as calcium deficiency diagnosis clinicians to provide reference and digital basis.
