                                                                                                                            微量元素檢測儀體格生長測量①身高測量:3歲以下兒童取仰臥位進行測量,將兒童扶正并保持雙腿伸直,頭部緊靠量床頭版,同時移動足板至接觸足跟,兩側讀數一致時讀取身高;3歲以上兒童采用立正姿勢站立測量,要求脫鞋脫帽并保持頭部正直,測量者將滑測板下調至頭頂并水平讀數。

                                                                                                                           、隗w質量測量:微量元素檢測儀采用微量元素檢測儀電子秤于兒童晨起空腹時進行測量,要求僅穿貼身衣物,赤足站在踏板中間并保持平穩。③骨齡測量:攝取左手及腕部X線片,由兒科醫師根據圖譜法進行評價。④體格發育:微量元素檢測儀每位兒童身高、體質量和骨齡均測量兩次取平均值,然后以年齡別身高(HAZ)、年齡別體質量(WAZ)和骨齡進行評估,然后根據《中國0~18歲兒童、青少年身高、體質量的標準化生長曲線》微量元素檢測儀計算Z評分,公式為(實測身高或體質量-同性別該年齡兒童平均身高或體質量)/該年齡同性別兒童身高或體質量標準差,以HAZ<-2為生長遲緩,WAZ<-2為低體重,≥2為超重;微量元素檢測儀采用骨齡-生活年齡(BA-CA)評價骨骼發育成熟情況,其中BA-CA<0為發育延遲,≥0為超前。

                                                                                                                            1.3統計學方法應用微量元素檢測儀統計軟件分析數據。計數資料組間比較采用檢驗,符合正態分布的計量資料以均數±標準差(x-±s)表示,微量元素檢測儀多組間比較采用單因素方差分析,兩兩比較采用獨立樣本t檢驗,不符合正態分布的計量資料以中位數(四分位數)表示,微量元素檢測儀采用秩和檢驗,相關性采用微量元素檢測儀相關系數分析,采用多重線性回歸分析研究微量元素缺乏對兒童體格發育的影響。以P<0.05為差異有統計學意義。
