An assessment of high risk sexual behaviour and HIV transmission among migrant oil workers in the Niger Delta area of Nigeria.
BACKGROUND
A cross--sectional behavioural survey undertaken amongst migrant oil-workers of an oil exploration outfit operating in the Niger-Delta of Nigeria with the aim of assessing the interplay of migrancy, high-risk sexual behaviour and HIV transmission.


METHODS
A total of 300 randomly selected migrant oil workers were assessed using structured questionnaires to evaluate key high - risk sexual behavioral parameters such as multiplicity of sexual partners, bisexuality (closet homosexuality), high grade sexual behaviour and lesbianism. Sampling period was two months with a control cohort of 200.


RESULTS
The prevalence of high risk sexual behaviour (HRSB) amongst the migrant oil workers was found to be 7.7% while low-risk sexual behaviour (LRSB) was 92.3%. There was no record of HRSB in the control group. We did not also encounter any lesbian sexual orientation in this study. The distribution of HRSB amongst the migrant oil workers showed that the commonest variety was bisexuality (closet homosexuality) with 10(43.5%) followed by high-risk sexual behaviour 7(30.4%), while the least common was multiplicity of sexual partners with 6 (26.1%). Furthermore, majority of these individuals 19 (82.6%) were above the age of 35 years. The index of condom-use and acceptance was high. Here 14 (60.9%) found condom-use convenient while 13 (56.5%) regularly used the condom.


CONCLUSIONS
This study confirms the existence of HRSB among migrant oil workers in the Niger delta. It is therefore advisable to focus interventionist and prevention programmes on this group which appear to be pivotal in the transmission and spread of HIV/AIDS in this environment.
