Psychosocial theories suggest that individuals' behavior is a reflect ion of their intention and ability to carry out a typical behavior. Th is study proposes to examine the psychosocial correlates of HIV-related sexual risk factor among male clients of female sex workers (FSWs). Data were used from a cross-sectional survey, collected using two-stage sampling, conducted among 2382 clients of FSWs in four states of India in November 2008. Clients were males who had engaged in paid sex with a FSW in the 12 months preceding the survey. Multiple logistic regression models were fitted to assess the effect of d ifferent psychosocial measure on HIV-related sexual risk factors: mu ltiple sexual partners, inconsistent condom use and self reported sexually transmitted infections (STIs). The odds of inconsistent condom use with FSWs was more among clients with low self-efficacy (Adjusted Odds Ratio (AOR): 2.2, 95% Confidence Interval (CI): 1.7-3.0), lo w perceived social support (AOR: 1.8, 95% CI: 1.3-2.6), lo w perceived personal norms (AOR: 1.7, 95% CI: 1.2-2.3) and lo w perceived access to condoms (AOR: 1.5, 95% CI: 1.1-2.0) than others. Similarly, experience of STI-related symptoms in the last 12 months was associated with low self-efficacy, low perceived social support and low perceived vulnerability. Findings highlight strong influence of psychosocial attitudes on HIV-related sexual risk factors among male clients of FSWs, suggesting the need for designing HIV p revention strategies to address psychosocial issues like self-efficacy, vulnerability and social support.

In this paper assignment based integer linear formulation presented for solving traveling salesman problem. Unfortunately, the assignment model can lead to infeasible solutions. Infeasibility removes by introducing additional constraints. Then this linear problem solved by open source software.
