BackgroundA multidimensional construct of social capital was employed to understand the relationship between social capital and migrants' HIV risk at destination place.MethodsThe study was undertaken among Rajasthani migrants of age 18 and above in Mumbai and Ahmedabad in India to collect data from 1598 migrants through survey method and from 93 migrants through qualitative methods from January to June 2007. Social capital was measured in terms of three domains: bonding, bridging and linking. HIV risk had three measures: having casual partner in last 12 months in the city; sex with a sex worker in the city in last 12 months; and no or inconsistent condom use with a sex worker in last 12 months.ResultsMigrants had substantial risk behaviour at destination: 385 respondents (24.1%) reported having one or more casual partners; 218 migrants (13.6%) had had sex with a sex worker; and 123 respondents (7.7%) reported no or inconsistent condom use with a sex worker in the last 12 months in the city. Migrants reported higher risk in Ahmedabad compared to Mumbai for all the three risk measures: 251 (31.6%) vs 134 (16.7%) reported casual partners; 138 (17.4%) vs 80 (10%) reported having had sex with a sex worker; and 96 (12.1%) vs 27 (3.4%). Bonding and linking domains of social capital had higher values for migrants in Ahmedabad than Mumbai. Bridging social capital was higher in migrants in Mumbai as compared to migrants in Ahmedabad. All the components of bridging social capital had higher values for migrants in Mumbai than Ahmedabad. Bonding and linking social capital behaved differently in Mumbai and Ahmedabad. In Mumbai, migrants had lower HIV risk if they had high linking social capital and had higher risk if they had high bonding social capital. In Ahmedabad, bonding social capital at high levels was associated with lower risk behaviour while linking social capital at high level was associated with higher risk. On the other hand, high levels of bridging social capital and components of bridging social capital were protective of HIV risk in both the cities see Abstract O2-S5.01 table 1.Abstract O2-S5.01 Table 1Multivariate relations of HIV risk with social capital (components) in Mumbai and AhmedabadScaleCasual partnersSex with commercial sex workerCondom use with CSWModel 1Model 2Model 1Model 2Model 1Model 2OR (CI)AOR (CI)OR (CI)AOR (CI)OR (CI)AOR (CI)Mumbai BO_communitaraian sense (low)0.53 (0.32 to 0.86)0.78 (NS)0.31 (0.17 to 0.60)0.47 (0.24 to 0.92) BR_particiaption (low)1.97 (1.19 to 3.27)1.90 (1.13 to 3.19)1.60 (NS)1.71 (NS) LI_personal trust in services (low)2.33 (1.31 to 4.15)2.39 (1.29 to 4.44)2.45 (1.08 to 5.52)2.84 (1.23 to 6.54) LI_reciprocal trusting relations with services (low)2.18 (1.11 to 4.28)2.96 (1.11 to 7.83)3.10 (1.16 to 8.31) Married or not (ref: married)0.16 (0.04 to 0.69) No. of working days in a month (ref: low)3.83 (1.31 to 11.2) Income (ref: low)1.67 (1.25 to 2.23)1.84 (1.26 to 2.67) Income steady/fluctuating (ref: fluctuating)1.93 (1.08 to 3.45) Mode of salary receipt (daily)1.39 (1.07 to 1.82)Ahmedabad BO_differences in community (low)2.34 (1.34 to 4.11)4.65 (2.39 to 9.02)6.71 (3.31 to 13.6) BO_personal trust and help (low)0.36 (0.23 to 0.57)0.36 (0.23 to 0.58)0.37 (0.19 to 0.72)0.30 (0.15 to 0.62)0.29 (0.14 to 0.61)0.28 (0.13 to 0.64) BO_generalized trust & help (low)1.96 (1.34 to 2.87)2.03 (1.36 to 3.03)2.68 (1.59 to 4.51)3.35 (1.88 to 5.98)3.38 (1.83 to 6.23)4.04 (2.14 to 7.62) BR_generalized trust & help (low)2.00 (1.17 to 3.42)1.90 (1.07 to 3.37)2.51 (1.26 to 4.99)2.61 (1.27 to 5.37) Living with wife or alone (ref: with wife)1.77 (1.45 to 2.17)2.42 (1.76 to 3.33)2.50 (1.73 to 3.61) Nature of job (ref: daily wage)1.49 (1.21 to 1.82) No. of working days in a month (ref: low)2.77 (1.12 to 6.88) Income (ref: low)1.66 (1.14 to 2.43)1.90 (1.22 to 2.96) Income steady or fluctuating (ref: steady)1.78 (1.26 to 2.51)1.91 (1.18 to 3.10)2.31 (1.29 to 4.14) Mode of salary receipt (daily)68 (0.48 to 0.96)0.61 (0.43 to 0.88)The table has results from the final logistic regression models.The low, medium and high category of social capital were treated as categorical categories and high social capital category for each component was selected as the reference category.Model 1: Social Capital Domains Only; Model 2: Social Capital Domains and Co-factors.Only significant associations shown here.High value of social capital measures is the reference category.BO, Bonding social capital; BR, Bridging Social Capital; LI, Linking social capital.ConclusionThis study was able to explore the mediating effect of social capital on migrants' HIV risk at the domain levels. Bridging kind of social capital with the host community and migrants from other states was associated with lower HIV risk behaviour. Further research should be undertaken in different epidemiological contexts to validate the findings of this study.
