背景:研究的目的是调查住院儿童营养不良的频率,并将国家生长标准与世界卫生组织(WHO)的标准进行比较。
方法:获得高度后,体重,250名1个月至5岁儿童的中上臂围值,根据Neyzi和WHO标准分别评估营养状况.年龄体重z评分(WAZ),身高体重z评分(WHZ),身高年龄z评分(HAZ),根据年龄计算上臂中围z评分(MUACz).WHZ<-2的患者被认为患有急性营养不良,而根据WHO的定义,HAZ<-2的人被认为患有慢性营养不良。
结果:根据WHO和乃子标准,z得分如下:WAZ(-0.53±1.54/-0.61±1.52),HAZ(-0.42±1.61/-0.45±1.38),WHZ(-0.33±1.26/无),MUACz(-0.58±1.31/无)。两个标准的WAZ评分之间的差异非常显着(P=0.0001),HAZ评分差异无统计学意义(P=0.052)。在我们的研究中,当根据世界卫生组织的标准进行评估时,急性和慢性营养不良的患病率分别为9.6%和13.6%,分别。<2岁人群的慢性营养不良患病率高于2-5岁人群(16.8%和4.5%,分别;P=0.012)。
结论:根据WAZ标准,WHO和国家Neyzi对营养不良的评估存在非常显著的差异,与世卫组织曲线可以普遍适用的说法相矛盾。在我们的研究中,急性和慢性营养不良的发生率很高,这表明营养不良在我国仍然是一个重大的营养问题。
BACKGROUND: The aim of the study was to investigate the frequency of malnutrition in hospitalized children and compare national growth standards with World Health Organization (WHO) standards.
METHODS: After obtaining height, weight, and mid-upper arm circumference values for 250 children aged 1 month to 5 years, nutrition status was assessed separately according to Neyzi and WHO standards. Weight-for-age z score (WAZ), weight-for-height z score (WHZ), height-for-age z score (HAZ), and mid-upper arm circumference z score (MUACz) were calculated based on age. Patients with WHZ < -2 were considered to have acute malnutrition, while those with HAZ < -2 were considered to have chronic malnutrition per WHO\'s definition.
RESULTS: According to the WHO and Neyzi standards, the z scores were as follows: WAZ (-0.53 ± 1.54/-0.61 ± 1.52), HAZ (-0.42 ± 1.61/-0.45 ± 1.38), WHZ (-0.33 ± 1.26/none), MUACz (-0.58 ± 1.31/none). The difference between WAZ scores for the two standards was highly significant (P = 0.0001), whereas the difference between HAZ scores didn\'t reach statistical significance (P = 0.052). In our study when evaluated according to WHO standards, the prevalence of acute and chronic malnutrition was 9.6% and 13.6%, respectively. The prevalence of chronic malnutrition in those aged <2 years was higher than in the 2-5 years age group (16.8% and 4.5%, respectively; P = 0.012).
CONCLUSIONS: There were highly significant differences in the assessment of malnutrition between the WHO and national Neyzi according to WAZ standards, contradicting the claim that WHO curves can be universally applicable. The high rates of acute and chronic malnutrition in our study indicate that malnutrition remains a significant nutrition problem in our country.
