二、如何评价小儿体格生长身体健康和营养状况良好的儿童,体格生长是按正常规律。由于儿童生长的遗传潜力不同,因而每个儿童生长的模式也不相同,但正常儿童的体洛生长都围绕在均值(中位数P_(50))周围,而不是沿着一条特定的线(不是沿着均值这条特定的线)。换句话说,不均值加减两个标准差(相当于在P_(97)与P_3)之间是正常范围。许多研究结果表明,均值减两个标准差(第3百分位P_3)是“临界线”,这条临界线将正常儿童与营养不良儿童分开。近年来,许多学者认为采用按年龄的体
Second, how to assess the physical growth of children in good health and nutritional status of children, physical growth is based on normal laws. Because of the different genetic potential of children’s growth, the pattern of growth varies from child to child, but normal children’s body mass growth is centered around the median (median P 50) rather than along a specific line Not along the mean of this particular line). In other words, adding or subtracting two standard deviations (equivalent to between P_ (97) and P_3) is a normal range. Many studies show that the mean minus two standard deviations (the 3rd percentile P_3) is the “critical line” that separates normal and undernourished children. In recent years, many scholars believe that using the body by age
