目的 :为了解该病的流行规律及分布特点 ,对今后的防治工作提供科学依据。方法 :用统一的流调表格和人口资料进行统计分析。结果 :我市乙型病毒性肝炎 (乙肝 )发病率为 0 .0 8‰ ,男女发病之比为 2 .6 9∶ 1,男性发病率高于女性 (χ2 =15 7.87,P<0 .0 1) ;年龄以 2 0岁组较高为 0 .14 (χ2 =90 .45 ,P<0 .0 1) ,其次为 30岁组 ;农民较高占 5 0 .5 7 ,发病率则以干部较高为 2 .76 (P<0 .0 1) ;平原地区发病率较高为 0 .10 ,其次为丘岭及山区 (χ2 =2 0 .2 5 ,P<0 .0 1) ;每年发病以夏秋季较多 ,但发病高峰不明显。该组病例构成比以夏季较多 ,占 2 9.94 ,其次是秋季 (χ2 =10 .34,P<0 .0 1)。结论 :性别间、不同职业间及地区间的发病均有高度显著性差异 ,10岁至 30岁组发病较高 ,是我市今后防治的重点 ,季节间发病有高度显著性差异 ,其原因有待继续探讨
Objective: To understand the epidemic pattern and distribution characteristics of the disease, provide scientific basis for prevention and treatment work in the future. Methods: Statistical analysis was conducted with a uniform flow chart and population data. Results: The incidence of hepatitis B in our city was 0.08 ‰, the ratio of male to female was 2.69: 1, the incidence of male was higher than that of female (χ2 = 15 7.87, P <0. 0 1). The age was higher in the 20-year-old group than in the 14-year-old group (χ2 = 90.45, P <0.01), followed by the 30-year-old group The highest was 2.76 (P <0. 01) in the cadres; the highest in the plain was 0.10, followed by the mound and mountains (χ2 = 20.25, P <0. 0 1); annual incidence in summer and autumn more, but the peak incidence is not obvious. This group of patients constituted more than in summer, accounting for 29.94%, followed by autumn (χ2 = 10.34, P <0.01). Conclusions: There is a highly significant difference in incidence among different sexes, occupations and regions, and the higher incidence among 10-year-olds and 30-year-olds is the focus of future prevention and treatment in our city. The reason for this is due to the highly significant difference between the seasons Continue to explore
