Geographic identification of high gonorrhea transmission areas in Baltimore, Maryland.

Geographic approaches to sexually transmitted infection (STI) research frequently seek to identify areas where outreach STI testing may most effectively interrupt continued transmission of STIs. Many of the studies are limited, however, in that they fail to control for racial/ethnic composition of the high prevalence areas. These studies thus may be merely identifying the broader sexual networks of the high morbidity population and not the high transmission networks within them. Cluster detection analysis may be an appropriate approach to identify critical STI disease transmission locations. This study determined whether statistically significant geographic clusters of high prevalence gonorrhea cases can be located after controlling for race/ethnicity. Using a spatial scan statistic, the authors analyzed reported cases of gonorrhea (n = 32,454) in Baltimore City, Maryland, from 1994 to 1999 geocoded to the primary address and aggregated to census block groups (n = 709). They adjusted for the underlying distribution of the population aged 15-39 years and percent African American per census block group. The results identified eight significant clusters of high STI prevalence areas, reinforcing the inference that risks for gonorrhea are associated with definable sociogeographic spaces. The areas identified may be critical to control STIs and may provide important direction for further study and targeted interventions.

Defining core gonorrhea transmission utilizing spatial data.

Spatial distribution of repeat and singly occurring gonorrhea in Baltimore, Maryland, was examined to identify clusters of core transmitters. Gonorrhea reported between 2001 and 2002 was geocoded and mapped. Those with more than one gonorrhea infection separated by more than 14 days during the 2-year period were considered repeaters. Other cases were treated as isolated events. Six definitions of core transmission were examined by census tracts with the highest quintiles of 1) cases for 2001, 2) cases for 2002, 3) rates for 2001, 4) rates for 2002, 5) counts of repeaters over the 2-year period, and 6) proportion of total cases that were repeaters. Of the 6,108 gonorrhea cases analyzed, 9% were repeaters. Repeaters were more likely to be female and younger. Core areas identified by definitions based on overall disease burden agreed well with each other but had poor agreement with definitions based upon repeat infections. Repeaters clustered to a greater extent at smaller distances than did singly occurring gonorrhea cases. Repeat gonorrhea infections are prevalent in Baltimore and likely represent behavior consistent with core transmission. Census tracts of core transmission defined by geographic distribution of repeat infections may indicate foci of highest risk sexual behaviors and high transmission.

Perceived social cohesion and prevalence of sexually transmitted diseases.

BACKGROUND: Although physical attributes have been shown to be associated with sexually transmitted disease (SD) rates, there is little information about the association between social attributes and STD rates. GOAL: The objective of this study was to determine the association between gonorrhea prevalence and perceptions of social cohesion in impoverished, urban neighborhoods. STUDY DESIGN: We conducted a street-based survey of 18- to 24-year-olds residing in selected census block groups in Baltimore City, Maryland. Census block groups eligible for selection were defined as impoverished (greater than 20% in poverty) and unstable (lowest 25th percentile for stability). From the eligible census block groups, 5 from high gonorrhea rate (greater than the 75th percentile) census block groups and 5 from the lower gonorrhea rate (lowest 25th percentile to equal or greater than the 75th percentile) census block groups were randomly selected. Participants within the 10 selected census block groups were recruited using a street-intercept method. Participants were asked about perceived social cohesion and control. RESULTS: Results showed that for young adults 18 to 24 years of age residing in high gonorrhea census block groups, the mean social cohesion index scores were 1.7 points lower than mean social cohesion index scores of the participants residing in the low gonorrhea census block groups (P <0.01). CONCLUSION: Future research needs to be conducted to determine the temporal association between gonorrhea prevalence and local social cohesion dynamics.

Discordant sexual partnering: a study of high-risk adolescents in San Francisco.

BACKGROUND: In sexual networks, bridge members engaging in discordant partnering play key roles in maintaining and transmitting sexually transmitted infections (STIs) within a population. GOAL: The goal was to characterize adolescents likely to engage in discordant sexual relationships with main and casual sex partners. STUDY DESIGN: Egocentric data about adolescents and their most recent sex partner(s) collected over 6 months were analyzed with use of logistic regression. RESULTS: History of STI, drug use, and meeting venue were significantly associated with discordant sexual partnering among high-risk adolescents. Participants with histories of high-risk behavior, e.g., hard drug use or STI, were more likely to have had a recent, dissimilar partner than those with lower-risk profiles. Particular meeting venues, such as clubs and street locations, were more likely to be associated with age-discordant, race-discordant, and drug use-discordant partnerships for females. CONCLUSION: Bridge members of adolescent sexual networks were more likely to have a history of STI, hard drug use, or meeting their sex partner through particular venues.
