目的:调查北京农村地区婴幼儿智力及运动发育特点及分析影响因素。方法:以经济状况为依据,采用分层抽样法随机抽取北京远郊地区10个县区2~30月龄共计356例健康婴幼儿,用贝利婴幼儿发展量表(BSID)测评智力发展指数(MDI)和运动发展指数(PDI)。结果:356例婴幼儿智力及运动发展总体状态良好,其中3、4、8、16、17、19、21月龄与中国城市婴幼儿智力量表粗分比较差异有统计学意义(P<0.05),2、3、4、8、9、12、15、17月龄与中国城市婴幼儿运动量表粗分比较差异有统计学意义(P<0.05)。母亲文化程度不同的婴幼儿间MDI差异有统计学意义(P<0.05),母亲文化程度为初中、本科的婴幼儿PDI相比差异有统计学意义(P<0.05);人工喂养、母乳喂养和混合喂养儿MDI相比差异有统计学意义(P<0.05),不同喂养方式之间PDI比较差异无统计学意义(P>0.05);家庭经济收入、家庭知识性与MDI呈正相关(P<0.05),其他影响因素与PDI无相关性(P>0.05)。结论:北京农村与中国城市婴幼儿智力运动的发育水平相比较差异不大,城市版量表内容基本适合北京农村的婴幼儿。不同的喂养方式、母亲文化程度、家庭经济收入、家庭知识性对婴幼儿智力运动发育有影响。 Objective: To investigate the characteristics of infant mental and physical development in Beijing rural areas and analyze the influencing factors. Methods: Based on the economic status, a total of 356 healthy infants from 2 to 30 months old in 10 counties in Beijing suburbs were randomly selected by stratified sampling method. The infant mental retardation index (BSID) MDI) and motor development index (PDI). Results: The intelligence and motor development of 356 infants and young children were in good condition. The difference of the scores of intelligence scores of infants and young children at 3, 4, 8, 16, 17, 19, 21 months in China was statistically significant (P <0.05 ), And there was significant difference between the age of 2, 3, 4, 8, 9, 12, 15 and 17 months and the gross score of infant city scale in China (P <0.05). There was significant difference in MDI between infants and toddlers with different education level of mother (P <0.05), and there was significant difference in PDI among junior high school and undergraduate infants (P <0.05). Artificial feeding, breastfeeding and (P <0.05). There was no significant difference in PDI between different feeding ways (P> 0.05). The family income and family knowledge were positively correlated with MDI (P <0.05) ), Other influencing factors had no correlation with PDI (P> 0.05). Conclusion: The developmental level of intelligence in infants and young children in Beijing rural areas and in Chinese cities is not different from that in other cities. The contents of urban scale basically fit the infants in rural Beijing. Different ways of feeding, mother’s education, family income and family knowledge have an impact on the development of mental and physical education in infants and young children.
