[HIV prevalence and risk factors among left-behind women in high HIV epidemic rural areas of Yunnan province].

OBJECTIVE

To understand the status of HIV infection and risk factors among those left-behind women (LBW) in high HIV epidemic rural areas.

METHODS

A cross-sectional investigation was conducted between March and May, 2015 in Dehong and Lincang prefectures, Yunnan province, where HIV appeared highly epidemic. Probability Proportion to Size (PPS) sampling method was used, and 500 cases were involved and tested for HIV antibody.

RESULTS

The total rate of HIV infection among LBW was 8.2% (41/500). The rate of HIV infection among LBWs whose husbands were on medication was 22.7% (30/132). Data from Multi-factor logistic regression analysis showed that the risk factors of HIV infection were: being minorities, education background lower than junior high school, widowed, living in Lincang prefecture, husband infected with HIV but did not consistently use condoms,etc. The rate of HIV infection among other LBWs was 2.8% (10/363). Data from Multi-factor logistic regression analysis showed that the risk factors of HIV infection would include: aged between 30-40 years, being minorities, education background lower than junior high school, divorced, living in Dehong prefecture, having had multiple-sex partners, husband coming home less than once a year,etc. The rate of HIV infection among drug users whose husbands did not take HIV medication was 20.0% (1/5).

CONCLUSION

HIV prevalence among LBWs in highly HIV epidemic areas was high, and the major risk factors related to their husbands were: being drug users or with HIV infected. Further effort should be made on consistently use of anti-HIV drugs and prevention of inter-marital sexual transmission. Comprehensive intervention should be carried out for LBWs who were having lower education background, being minority and having multiple-sex partners.
