2. STI BEHAVIORAL EPIDEMIOLOGY: NEW PARADIGM Population-level parameters, including sexual network patterns Pattern of linkages critical in STI transmission –e.g., sexual interaction between subpopulations African Americans –Dissortative mixing (peripheral blacks 5x as likely as whites to choose partner from core) –Segregated partner choices (more likely to choose other blacks as partners) –Laumann E, Youm Y. STDs 1999; 26:250 Prevalence of concurrent partnerships

10. FOCUS GROUPS Employment and economic opportunities “There are no jobs for anybody coming right out of high school…” “You can have all the schooling in the world, but if you’re black you can’t get a good job.” “Most of the temporary agencies …like to send the blacks to jobs in factories…” “Every job here is dead end with terrible pay.”

11. FOCUS GROUPS Racism/Race relations “A lot of things are divided racially… you have a white side of town, and the black side…doesn’t usually mix. It’s sort of covert. You don’t have white folks walking around in robes or anything, but in the schools and things you can see it.” “It’s hard to get a loan to get a house. Banks don’t just give black people loans. You got to know somebody.”

12. FOCUS GROUPS Racism/Race relations (cont) “I would say it was greatly polarized. When I was going to school here in the high school, the type of classes you could get into, like the college prep courses, had a lot to do with what type of family you came from, your race,…”

13. FOCUS GROUPS Relationships between men and women “To get to the next semi-urban city, if you don’t have a job, or a good education, you’ve got to depend on somebody to get you there. For young black women, it’s not a good position to be in without a good job or a good education.” “The choices in men are very limited around here. I guess the women put up with the men they have because there aren’t that many.”

14. FOCUS GROUPS Relationships between men and women “There’s so many black men in prison, strung out on drugs, or dead, that if a decent black lady finds a decent black man, she’s going to do whatever it takes to get him.” “It’s not that many good men worth anything in this area.” “The ratio of women to men is very high.”

15. FOCUS GROUPS Concurrent partnerships “Most [unmarried] couples aren’t going to be true to each other.” “If they aren’t planning on getting married, they’re probably going to have relationships on the side.” “I say it’s quite common for people to be involved in relationships with more than one person at a time.”

16. FOCUS GROUPS Respondents described: Pervasive economic and racial oppression Lack of community recreation, boredom, resultant substance abuse Shortage of black men (higher mortality and incarceration rates Widespread concurrency among unmarried people Conclusion: Contextual features may promote sexual patterns that transmit STIs Adimora, Schoenbach, et al.
