目的:研究黄冈市城区3岁幼儿身高增长的季节性特点和规律,为促进幼儿体质健康发育和开展幼儿卫生保健工作提供科学依据。方法:2006年9月～2007年9月对黄冈市实验幼儿园2003年出生的90名幼儿(男43名,女47名)的四季身高增长情况进行了5次跟踪测量和统计分析。结果:黄冈市3岁幼儿身高增长的最佳季节为春季和秋季,最差增长季节为冬季,男性幼儿在春季和秋季以及夏季和冬季之间身高增长量比较差异无统计学意义,春、秋季与夏、冬季之间比较则差异有统计学意义,而女性幼儿四个季节的身高增长量比较差异均有统计学意义。两性间身高增长量季节比较,春季和夏季差异无统计学意义(P>0.05),秋季和冬季差异有统计学意义(P<0.05)。结论:黄冈市3岁幼儿身高增长表现出明显的季节性特征,且女性幼儿生长受季节因素影响的程度大于男性幼儿。
Objective: To study the seasonal characteristics and regularity of height growth of 3-year-old children in Huanggang city, and to provide a scientific basis for promoting physical health development of young children and carrying out child health care. Methods: From September 2006 to September 2007, the height growth of 90 infants (male 43, female 47) born in experimental kindergarten in Huanggang City in 2003 was measured and tracked 5 times. Results: The best height growth of 3-year-old children in Huanggang city was spring and autumn, the worst growth season was winter, and there was no significant difference in height growth among male children in spring and autumn and between summer and winter. Compared with summer and winter, the difference was statistically significant, while the height growth of female children in four seasons were statistically significant differences. There was no significant difference in the height growth between the two sexes in spring and summer (P> 0.05), but there was a significant difference between autumn and winter (P <0.05). Conclusion: The height growth of 3-year-old infants in Huanggang shows obvious seasonal characteristics, and the growth of female infants is more affected by seasonal factors than that of male infants.
