The summary statistics for those that travel one to four, or five or more time, are compared to those that do not travel. Significance is shown with stars. On average, those who travel frequently are slightly older. The mobile population is more likely to live in urban areas, be employed and have a higher level of education. The mean number of sex partners increases with mobility. Odds ratios are calculated adjusting for age, employment status, marital status and education. Stars denote the significance according to the following P-values:
*P <0.001
*0.001≤P<0.01
0.01≤P<0.05.
Mobile women and men have a greater odds ratio of having two or more sex partners and having concurrent partnerships than those who did not travel. Concurrent partnerships are calculated amongst those who had sex in the last 12 months. Mobile men have greater odds of reporting four or more lifetime sex partners. Men who made five or more trips have greater odds of being HIV infected than those who did not travel.
