江苏省吕四港渔民艾滋病／性病高危行为流行病学研究

High-risk behaviors related to AIDS/STDs infections among fishermen in Lv-si harbor, Jiangsuprovince

目的了解江苏省吕四港地区渔民艾滋病，陛病相关高危行为，分析其影响因素。方法以横断面调查方法收集目标人群的人口学信息、艾滋病，性病高危行为及潜在影响因素等信息，采用非条件logistic回归分析高危行为的影响因素。结果共有817名渔民参与调查。临时性行为和商业性行为是渔民感染艾滋病广陛病的主要高危行为，报告率分别为18．1％和28．9％。渔民高危性行为的危险因素：流动性（OR=1．516，P=0．038）、平时性生活频次高（OR=1．422，P=0．002）、离异或丧偶婚姻状态等（OR=7．527，P=0．014）；保护因素有饮酒少（OR=0．803，P=0．053）、无性病史（OR=0．268，P=0．001）、初次性行为≥22岁（OR=0．440，P=0．000）、不接受多性伴（OR=O．662，P=0．023）和商业性行为合法化的态度（OR=0．612，P=0．007）。结论渔民中存在着感染艾滋病／性病的风险；临时性行为与商业性行为是常见的高包行为。

Objective To investigate the high-risk behaviors related to acquared immunedeficiency syndrome/sexually transmitted disease （AIDS/STDs） infection among fishermen in Lv-si harbor, Jiangsu province. Methods A cross-sectional study was designed to investigate the research participants＇ demographic characteristics, high-risk behaviors that related to AIDS/STDs. Logistic regression was performed to measure the associations between potential risk factors and reported potential high-risk sexual behavior. Results 817 fishermen participated in the study and casual or commercial sex activities appeared to be the main high-risk behavior for AIDS/STDs infection in the target population. The rates of casual and commercial sex reported were 18.1% and 28.9% among fishermen. Risk factors associated with AIDS/STDs related high-risk behaviors among fishermen were high mobility （OR= 1.516, P=0.038）, higher lifetime sex frequency （OR= 1.422, P=0.002） and unmarried status （OR=7.527, P=0.014）. Protective factors against high-risk behaviors were low intake of alcohol （OR=0.803, P=0.053） , negative STD history （OR=0.268, P=0.001） , age of initial sexual intercourse at or older than 22 years （OR=0.440, P= 0.000） of age, as well as negative attitude toward multiple sexual partners （OR=0.662, P=0.023） and legitimation for commercial sex （OR=0.612, P=0.007）. Conclusion There were risk behaviors of AIDS/STDs in those infected fishmen. Casual and commercial sex were common high-risk behaviors.
