[目的]探讨沈阳地区消化性溃疡患者的入院时间的规律性。[方法]对中国医科大学附属第一医院2005~2015年收治的1 956例消化性溃疡患者病例资料进行回顾性分析,采用圆形分布统计方法确定其入院高峰日、高峰期及高峰季节。[结果]2005~2015年消化性溃疡患者入院高峰在春、冬季,11年数据分析提示合计平均角为75.563 1°,相当于高峰日为3月19日(Z=2.9957,Z>Z_(0.05),P<0.05),入院高峰期为11-16至次年07-24。[结论]沈阳地区消化性溃疡患者发病有明显季节性,在消化性溃疡防治工作中要充分考虑其发病的季节特点,并采取相应措施以降低其发病率。
[Objective] To study the regularity of admission time in patients with peptic ulcer in Shenyang area. [Methods] The data of 1 956 cases of peptic ulcer patients admitted to the First Affiliated Hospital of China Medical University from 2005 to 2015 were retrospectively analyzed. The circular distribution statistics method was used to determine the peak day, peak period and peak season of admission. [Results] The data of 15 years from spring to winter and 11 years from 2005 to 2015 showed that the average angle of admission was 75.563 1 °, corresponding to the peak day of March 19 (Z = 2.9957, Z> Z 0.05 ), P <0.05). The peak period of admission was 11-16 and the following year was 07-24. [Conclusion] The incidence of patients with peptic ulcer in Shenyang is obviously seasonal. In the prevention and treatment of peptic ulcer, we should take full account of the seasonal characteristics of its onset and take corresponding measures to reduce its incidence.
