摘要:
目的 研究影响丙型肝炎抗体的相关因素及评价近7年来延边州对于丙型肝炎的预防效果。 方法 2020年随机筛选1184例延边地区居民,采取指尖血标本,使用胶体金法试剂检测丙型肝炎抗体,将2020年丙型肝炎抗体阳性率与2013年的数据进行对比分析。计数资料组间比较采用χ2检验或Fisher精确检验,Fisher精确检验后使用成对比较分析。 结果 2020年筛选的延边州居民丙型肝炎抗体阳性率(6.42%)低于2013年(10.60%)(χ2=11.212,P=0.001);2020年各个年龄段之间丙型肝炎抗体阳性率经Fisher精确检验(2×C)结果显示,5个年龄段之间差异具有统计学意义(χ2=29.478,P<0.001);采用Bonferroni调整后成对比较显示≥60岁组与50~59岁组、40~49岁组、30~39岁之间差异具有统计学意义(χ2值分别为11.268、14.804、9.293,P值均<0.01),其余各组间差异无统计学意义(P>0.01)。朝鲜族抗体阳性率(10.45%)显著高于非朝鲜族抗体阳性率(5.50%)(χ2=7.236,P=0.007);在农民群体中,2020年丙型肝炎抗体阳性率(7.16%)低于2013年(19.74%)(χ2=36.604,P<0.001);农村地区(7.33%)丙型肝炎抗体阳性率高于城市(4.26%)(χ2=3.882,P=0.049)。 结论 丙型肝炎抗体阳性率主要与年龄、民族、职业、地域有关。7年来延边地区丙型肝炎抗体阳性率较前下降,延边州对于丙型肝炎的初步防治效果较为显著。 Abstract:Objective To investigate the influencing factors for hepatitis C antibody and the preventive effect of hepatitis C in Yanbian Prefecture of China in the recent 7 years. Methods A total of 1184 residents in Yanbian were randomly selected in 2020, peripheral blood samples were collected, and the colloidal gold method was used to detect hepatitis C antibody. The positive rate of hepatitis C antibody in 2020 was compared with the data in 2013. The chi-square test or the Fisher's exact test was used for comparison of categorical data between groups, and then pairwise comparison was performed. Results The positive rate of hepatitis C antibody in Yanbian residents screened in 2020 was significantly lower than that in 2013 (6.42% vs 10.60%, χ2=11.212, P=0.001). The Fisher's exact test (2×C) was performed for the positive rate of hepatitis C antibody between different age groups in 2020, and the results showed that there was a significant difference between the 5 age groups (χ2=29.478, P < 0.001). Pairwise comparison after Bonferroni adjustment showed that there was a significant difference between the≥60 years group and the 50-59 years group, between the≥60 years group and the 40-49 years group, and between the≥60 years group and the 30-39 years group (χ2=11.268, 14.804, and 9.293, all P < 0.01), while there was no significant difference between the other groups (P > 0.01). The Chinese Korean population had a significantly higher positive rate of antibody than the non-Chinese Korean population (10.45% vs 5.50%, χ2=7.236, P=0.007). As for the farmers, the positive rate of hepatitis C antibody in 2020 was significantly lower than that in 2013 (7.16% vs 19.74%, χ2=36.604, P < 0.001). The positive rate of hepatitis C antibody in rural areas was significantly higher than that in urban areas (7.33% vs 4.26%, χ2=3.882, P=0.049). Conclusion The positive rate of hepatitis C antibody is mainly associated with age, nationality, occupation, and region. There is a reduction in the positive rate of hepatitis C antibody in Yanbian in the recent 7 years, suggesting that Yanbian Prefecture has achieved a marked effect in the prevention and treatment of hepatitis C. -
