Social Support and HIV Risks Among Migrant and Non-Migrant Market Workers in Almaty, Kazakhstan.

(1) higher level of perceived social support [Enhancing Recovery in Coronary Heart Disease (ENRICHD) Social Support Instrument (ESSI score)] was associated with a lower likelihood of having sex with a female sex worker (FSW) [OR = 0.952 (0.927, 0.978) p < .001]; (2) higher availability of friends was associated with a higher likelihood of having STIs [OR = 1.244 (1.007, 1.537), p < .05]; (3) larger network size was associated with a higher likelihood of having STIs [OR = 1.201 (1.026, 1.407), p < .05]; (4) loneliness was associated with an increased likelihood of having unprotected sex with any female partner [RR = 1.102 (1.027, 1.182), p < .05]. Results suggest that social support factors should be considered as a component of HIV and STI prevention programs for male migrant workers from Central Asia in Kazakhstan.
