OBJECTIVE To explore the risk sexual behaviors related to AIDS among different status of income among men who have had sex with men and to provide relevant interventions for AIDS control and prevention. METHODS Study objectives were recruited through target sampling and anonymous questionnaires were adopted. Men's sexual behaviors were reported under the categories as high, mid or low-income. RESULTS The total number of same-gender partners with high and mid-income was 110.17 with an average of 71.97. Among high and mid-income men, the number of partners for oral sex was 62.45, with an average of 46.6 respectively. The number of partners having anal intercourse was 52.21, with an average of 32.3, obviously more than in the low-income group (P < 0.01). The rates of condom use among high-income and mid-income men were 79.03% and 77.29% respectively and were higher than that those among low-income men (P < 0.01). The percentage of high-income men who recently had had sex with male sex workers was 3.81%, higher than that of the mid-income and the low-income men (P < 0.01). The rates of high-income and mid-income men who had paid for sex from men were 24.27% and 14.7% respectively and were all higher than that of the low-income men with the highest in the high-income group (P < 0.01). The rates of high-income and mid-income men who were male sex workers were 6.72% and 11.05% respectively, which were all lower than that from the low-income group (P < 0.01). CONCLUSION The characteristics of sexual behaviors related to AIDS were different in the three groups. In high-income group, risk sexual behaviors also existed, suggesting that different interventions for different people should be developed.
