【摘要】 目的:对广州市2岁以下城市儿童的生长发育和营养状况进行评价和分析。方法:选择8个社区共计1874例健康儿童,测量儿童的身高、体重,同时对儿童家庭状况、喂养史、父母受教育的程度进行调查。结果:本次调查2岁以下城市儿童各年龄组男女性别差异无显著性(P>0.05)。各年龄组内男女之间比较身高、体重和BMI差异均无统计学意义(P>0.05),提示生长发育呈正态分布。但各个年龄组儿童的体重、身高(长)与2005年全国标准相比较,在较多的组别低于全国的标准,且差异具有统计学意义。年龄别体重(WAZ)评价指标:低体重的检出率较低,各个年龄组男女童有0.74%～3.8%的WAZ小于-2,各个年龄组都有WAZ大于2的情况。年龄别身高(长)(HAZ)评价指标:各个年龄组男女童有0.68%～7.59%的HAZ小于-2的情况,1.85%～7.14%儿童的HAZ大于2。BMI在各年龄组男、女童呈正态分布,男女之间差异均无统计学意义(P>0.05)。结论:体重、身长、BMI三项指标综合考虑能更客观反映该地区儿童的生长发育和营养状况。更多还原

【Abstract】 Objective To analyze and evaluate the growth and nutritional status of urban children under 2 years old in Guangzhou. Methods A total of 1 874 healthy children in 8 communities in Guangzhou were included , the height and weight were measured, and the family status, feeding history, parental educational degree were surveyed. Results There was no significant difference of the gender in urban children under 2 years old (P > 0.05). The height, weight and BMI were not significantly different between male and female (P > 0.05), and were lower than the 2005 national standards (P < 0.05). The detection rate of low weight was low, and there were 0.74%-3.8% of children whose WAZ < -2, also there were cases whose WAZ > 2. Meanwhile, there were 0.68%-7.59% of children whose HAZ < -2, and were 1.85%-7.14% of children whose HAZ > 2. Conclusion The combination of weight, height, and BMI could more objectively reflect the children′s growth and nutritional status.更多还原
