■我国现行的国家学龄前儿童生长发育标准是2003年制定的,存在许多不足。有必要构建更科学的百分位曲线和增长参考标准,中国儿童的发展和健康状况。
■基于2010年和2014年测量的中国31个省份的物理和健康数据,采用GAMLSS模型构建了增长参考标准和相关曲线。
■我们获得了身高年龄百分位数曲线和Z分数曲线的生长参考标准,坐姿的年龄,年龄体重,中国学龄前儿童的胸围。所有指标的C50百分位数在3.0~6.5岁之间呈明显的上升趋势。如,男孩和女孩的身高分别增加了21.1厘米和20.3厘米,男孩和女孩的坐姿分别增加了10.3厘米和10.1厘米,男孩和女孩的体重分别增加了7.1公斤和6.3公斤,男孩和女孩的胸围分别增加了6cm和5.2cm。
■本研究提供的儿童生长发育图表为学龄前儿童的生长发育评估提供了有效的监测和个性化评估工具,以及减少营养不良,预防和控制儿童肥胖。建议在某些领域使用,如儿童健康,医疗和公共卫生。
UNASSIGNED: The current national growth and development standard of preschool children in China was formulated in 2003, which has many deficiencies. It is necessary to construct more scientific percentile curve and growth reference standards in order to evaluate more effectively the growth, development and health status of Chinese children.
UNASSIGNED: Based on the physical and health data of 31 provinces in China measured in 2010 and 2014, the GAMLSS model was used to construct the growth reference standard and correlation curve.
UNASSIGNED: We obtained growth reference standards for percentile curve and Z-score curve of height-for-age, sitting height-for-age, Weight-for-age, Chest circumference-for-age of Chinese preschool children. The C50 percentile of all indicators showed an obvious increasing trend with aged 3.0 to 6.5. Such as, the height of boys and girls increased by 21.1cm and 20.3cm respectively, the sitting height boys and girls increased by 10.3cm and 10.1cm respectively, the weight of boys and girls increased by 7.1 kg and 6.3 kg respectively, the Chest circumference of boys and girls increased by 6cm and 5.2 cm respectively.
UNASSIGNED: The children\'s growth and development charts provided in this study provide effective monitoring and personalized evaluation tools for the growth and development assessment of preschool children, as well as for the reduction of malnutrition, prevention and control of childhood obesity. It is recommended to be used in some areas such as child health, medical treatment and public health.
