2017—2021年内蒙古自治区新报告HIV/AIDS病例晚发现情况分析

目的 分析2017—2021年内蒙古自治区新报告艾滋病感染者/艾滋病病人（HIV/AIDS）晚发现的情况，为制定进一步的防控措施提供依据。方法 从艾滋病综合防治信息系统中，选取2017—2021年内蒙古自治区新报告的HIV/AIDS病例进行分析；计算晚发现比例；采用χ2趋势检验分析各年度晚发现比例的变化趋势；运用多因素logistic回归模型对其影响因素进行分析。结果 2017—2021年内蒙古自治区新报告HIV/AIDS病例共计4 464例，其中晚发现病例1 248例，晚发现比例为27.96%。各年度晚发现比例呈现上升趋势（χ2 = 7.655，P＜0.05）。蒙古族各年度晚发现比例差异无统计学意义（χ2 = 1.806，P = 0.179）。多因素logistic回归结果表明年龄、文化程度和样本来源是晚发现的主要影响因素，随着年龄的增长晚发现比例升高，其中与0～19岁组相比，50～59岁组及60岁以上病例OR值（95%CI）分别为8.859（5.078～15.456）和8.117（4.480～14.707）；与大专及以上文化程度相比，高中或中专以及初中的晚发现风险较高，其OR值（95%CI）分别为1.290（1.068～1.566）和1.270（1.055～1.533）；与医疗机构相比，检测咨询和其他来源的OR值（95%CI）分别为0.570（0.469～0.681）和0.430（0.342～0.538）。结论 2017—2021年内蒙古自治区新报告HIV/AIDS病例晚发现比例逐年升高，蒙古族各年度晚发现比例变化不明显。年龄、文化程度和样本来源是造成晚发现的主要影响因素，应当采取有效措施以推动病例的早期发现。

Analysis on late discovery of newly reported HIV/AIDS cases in Inner Mongolia Autonomous Region from 2017 to 2021

Objective To analyze the late discovery of newly reported HIV/AIDS cases in Inner Mongolia Autonomous Region from 2017 to 2021, and to provide evidence for further prevention and control measures. Methods The newly reported HIV/AIDS cases in Inner Mongolia Autonomous Region from 2017 to 2021 were selected for further analysis from AIDS Integrated Prevention and Control Information System. The proportion of late discovery was calculated. The chi-square trend test was used to analyze the change trend of the proportion of late discovery each year, and the multivariate logistic regression model its influencing factors. Results From 2017 to 2021, a total of 4 464 new HIV/AIDS cases were reported in Inner Mongolia Autonomous Region, of which 1 248 were of late discovery (27.96%). The proportion of late discovery showed an upward trend in different years (χ2=7.655, P＜0.05). There was no statistically significant difference in the proportion of late discovery of the Mongolian in each year (χ2=1.806, P=0.179). The multivariate logistic regression results showed that age, education level, and sample source were the main influencing factors of late discovery. The proportion of late discovery increased with age. Compared with age group of 0 to19 years, the OR values (95%CI) of age group of 50 to 59 years and ＞60 years were 8.859 (5.078-15.456) and 8.117 (4.480-14.707), respectively. Compared with college education or above, the risk of late discovery was higher in high school or technical secondary school and middle school, and the OR value (95%CI) was 1.290 (1.068-1.566) and 1.270 (1.055-1.533), respectively. Compared with hospital source, the OR values (95%CI) of from testing consultation institutes and other sources were 0.570 (0.469-0.681) and 0.430 (0.342-0.538), respectively. Conclusion From 2017 to 2021, Inner Mongolia Autonomous Region’s newly reported HIV/AIDS cases of late discovery have increased year by year, but the proportion of late discovery of the Mongolian has not changed significantly. Age, education level, and sample source are the main influencing factors for late discovery. Effective measures should be taken to promote early discovery of HIV/AIDS cases.
