【摘要】 目的:了解该地区新生儿平均出生体重的发展变化情况,指导妇幼保健工作。方法:利用深圳市妇幼卫生信息系统获得新生儿出生体重资料和数据并进行统计分析。结果:该地区新生儿平均出生体重(3 181.62±489.70)g,其中男婴(3233.59±496.65)g,女婴(3 118.18±472.87)g,比全国平均水平低。低出生体重构成比为5.62%,比全国水平高。平均出生体重呈逐年递增趋势。月平均出生体重存在明显差异(F=14.63,P<0.05),两者可以模拟一元三次方程Y=B0+B1X+B2X2+B3X3(1≤X≤12)。结论:应重视新生儿平均出生体重的研究,以进一步提高保健质量,改善孕妇营养,提高出生人口体质,降低婴儿死亡率。更多还原

【Abstract】 Objective:To grasp the developing and change of the average birth weight of newborns in local district,in order to guide the work of maternity and child health care.Methods:The data obtained from the work of maternity and child health care system of Shenzhen were analyzed.Results:The average birth weight of newborns（3 181.62±489.70）g;males was（3 233.59±496.65）g,females was（3 118.18±472.87）g was lower than those of China.The low birth weight infant was above the level of the whole country,which was 5.62 percent.The average birth weight was increasing year by year.There was significant difference of the average birth weight of newborns among 12 months（F=14.63,P<0.05）.The best-fitted mathematical model of month average birth weight was Y=B₀+ B₁X+ B₂X² + B₃X³（1≤X≤12）.Conclusion:The study of the average birth weight of newborns should be paid more attention to improve the quality of health care,the nutrition of the pregnant women,the health of the newborns to dramatically reduce infant mortality.更多还原
