【摘要】 目的探讨烟台市学龄前儿童生长发育Z评分、身体素质状况以及Z评分与身体素质间的关系,为儿童保健工作提供科学依据。方法以2010年国民体质监测烟台地区幼儿组资料中3～4岁儿童362人为研究对象,计算年龄别体重、年龄别身高、年龄别体重指数三项Z评分,及Z评分与身体素质间进行Pearson相关分析。结果 Z评分均值均为正值,低体重、生长迟缓的发生率极低,但肥胖发生率较高(4岁男童高达16.5%);儿童的身体素质存在年龄和性别差异(P<0.05);Z评分与部分身体素质指标间存在一定相关关系(P<0.05),但密切程度不高(r值均未超过0.30)。结论烟台市学龄前儿童生长发育Z评分保持在较高水平;儿童身体素质与年龄和性别有关;Z评分与部分身体素质间有低度相关关系。应采取积极措施调整儿童饮食习惯、加强体育锻炼,预防肥胖、提高身体素质。更多还原

【Abstract】 Objective To investigate the Z scores for growth and development,physical fitness,and the relationship between them in preschool children in Yantai City,China,and to provide scientific evidence for health care in children.Methods A total of 362 children aged 3 to 4 years,whose data were recorded in the National Physical Fitness Survey in Yantai in 2010,were included in the study.Z scores for weight-for-age,height-for-age and body mass index-for-age were calculated.The relationship between Z scores and physical fitness was determined by Pearson′s correlation analysis.Results The mean Z scores were all positive numbers.The prevalence rates of underweight and growth retardation were very low,but that of obesity was relatively high(up to 16.5% in 4-year-old boys).There were differences in physical fitness between children of different ages and between boys and girls(P<0.05).The Z scores showed correlation with some physical fitness indices(P<0.05),but they were not closely correlated as the value of r was not more than 0.30.Conclusions Z scores for growth and development remain at relatively high levels in preschool children in Yantai.The physical fitness is associated with age and gender in these children.There are weak correlations between Z scores and some physical fitness indices.Effective measures should be taken to adjust dietary habits and promote exercise for children,thus preventing obesity and improving physical fitness.更多还原
