摘要
应用Poisson周期回归模型对全国29省、市、自治区脊柱裂1072例出生监测资料进行分析,借助逐步回归法对模型中的三角函数项进行筛选,以判断各省、市、自治区有无季节波动,并进一步计算其高峰位置。结果表明在我国脊柱裂存在季节波动的地区基本在北方,北方的高峰位置大都出现在冬春季节,与国外多数报道一致。结论有助于脊柱裂病因探讨。
The Poisson periodic regression models were employed to detect the seasonal variations of the monthly incidence rates of spina bifida in monitoring data from Oct.1986 to Sep. 1987 in 29 provinces of China. The stepwise technique was used in fitting models to select the periodic functions. The peak times were also calculated if the seasonal variations were detected. The authors concluded that the spina bifida of many provinces in north China occurred in seasonality with one peak in Winter , and the other in Spring , which isthe same as most of the reports.
