Community perceptions of bloody diarrhoea in an urban slum in South Asia: implications for introduction of a Shigella vaccine.

Understanding local perceptions of disease causation could help public health officials improve strategies to prevent bloody diarrhoea. A cross-sectional survey was conducted in Dhaka, Bangladesh to elicit community beliefs about the causes of and prevention strategies for bloody diarrhoea. Between March and June 2003, we interviewed 541 randomly selected respondents. Overall, 507 (93%) respondents perceived that a vaccine could prevent bloody diarrhoea. If a vaccine provided lifetime protection, 445 (83%) respondents stated that they would opt to get the vaccine and would pay a median of $0·05 (range U.S.$0·01-0·15) for it, equivalent to <1% of their median weekly income. There was almost universal perception that an effective vaccine to prevent bloody diarrhoea was highly beneficial and acceptable. While respondents valued a vaccine for prevention of bloody diarrhoea, they were only willing to pay minimally for it. Therefore, achieving a high rate of Shigella vaccine coverage may require subsidy of vaccine purchase.

High prevalence of asymptomatic STDs in incarcerated minority male youth: a case for screening.

BACKGROUND AND OBJECTIVES: To assess STD prevalence among a sample of incarcerated minority male youth in a southern US city. METHODS: A consecutive entrant, cross-sectional study of 284 minority males 14 to 18 years was performed. All adolescents were screened for gonorrhea and chlamydia using ligase chain reaction tests. RESULTS: Eighteen percent of youth were identified as having either gonorrhea, chlamydia, or both. Approximately 84% of those with sexually transmitted diseases (STDs) self-reported having no symptoms. Failure to use condoms in the past month was significantly associated with a positive test result for STDs (odds ratio = 1.9, 95% CI = 1.1-3.3). CONCLUSIONS: The findings indicate an urgent need for routine STD screening and STD-prevention programs for adolescent males in detention facilities. A study of 284 detained black male adolescents revealed 18% prevalence of gonorrhea, chlamydia, or both. Approximately 84% of those with sexually transmitted diseases self-reported not having symptoms.

Changes in incarcerated adolescents' human immunodeficiency virus knowledge and selected behaviors from 1988 to 1996.

Data were collected from juveniles in Alabama and Florida correctional facilities. The samples were closely demographically matched. Analysis indicated significant increases in knowledge about human immunodeficiency virus between 1988 and 1996 and increased sexual risk behaviors. Knowledge levels were lower for ethnic minority groups and boys, suggesting ethnic- and gender-specific pedagogical aids are needed.

Health risk behaviors of African American adolescents with mild mental retardation: prevalence depends on measurement method.

Health risk behaviors (e.g., substance use, violence, suicide, and car safety) of 194 14- to 17-year-old African American urban adolescents with mild mental retardation from special education classes were measured. One group was assessed using a confidential individual interview method, and an individually matched group was assessed with an anonymous group survey method. Participants completing the anonymous survey reported engaging more frequently in risk behaviors that respondents typically consider sensitive. In comparison to national and state populations of African American adolescents, urban African American adolescents with mild mental retardation appear to be at substantial elevated risk for engaging in alcohol binge drinking and weapon and gun carrying. Findings were discussed relative to cognitive and social deficits inherent in mild mental retardation.
