National guidance on sexual health in England recommends service development to meet the specific needs of ethnic minority populations. Our aim was to evaluate mode of referral, number of sexually transmitted infections (STIs) diagnosed, and the offering and uptake of HIV testing in patients of South Asian ethnicity. A retrospective case-control study was undertaken in two London genito-urinary (GU) medicine clinics. There were 250 case-control pairs with approximately equal numbers of men and women. South Asians were less likely to have an STI (Odds ratio [OR] 0.66, 95% confidence interval [CI] 0.45, 0.97) or to report risk factors for HIV (OR 0.45, 95% CI 0.28, 0.71). Offering and uptake of HIV antibody testing were high in both South Asian and non-South Asian groups (OR 0.62, 95% CI 0.27, 1.51). South Asians were significantly more likely than controls to have been referred by other medical services rather than self-referred (OR 2.00, 95% CI 1.32, 3.01), which is in keeping with poorer access to GU medicine services in London.

Studies have suggested that positivity can be used to estimate the prevalence of Chlamydia trachomatis in large-scale chlamydia screening programmes. A recent pilot of opportunistic screening in England estimated that the prevalence among 16-24-year-old women in Portsmouth and Wirral was 9.8% and 11.2%, respectively. This study assessed the continued validity of positivity as an approximate for prevalence. We re-analysed data from the Chlamydia Screening Pilot to estimate positivity,calculated as total positive tests divided by total tests, and compared these estimates with the previously reported prevalence, measured as the number of women testing positive divided by the total number of women screened. Overall positivity was 9.4% in Portsmouth and 11.0% in the Wirral; these estimates were not statistically different from prevalence, regardless of health-care setting, age group or symptoms. We conclude that positivity can be used as a proxy for prevalence.

ObjectivesThe aim of the paper was to describe the association of religion with HIV outcomes in newly diagnosed Africans living in London. MethodsA survey of newly diagnosed HIV-positive Africans attending 15 HIV treatment centres across London was carried out between April 2004 and February 2006. Confidential self-completed questionnaires were used, linked to clinical records. Bivariate analyses were conducted to ascertain whether religious beliefs were associated with late diagnosis, antiretroviral therapy, and immunological and virological outcome 6 months post diagnosis. ResultsA total of 246 Black Africans were eligible and included in the analysis: 62.6% were women, and the median age was 34 years. The median CD4 count at diagnosis was 194 cells/mL (range 0-1334 cells/mL) and 75.6% presented late, as defined as a CD4 count < 350 cells/mL. Most participants were religious: non-Roman Catholic Christians (55.7%), Roman Catholics (35.2%) and Muslims (6.1%). Only 1.2% stated that they did not have a religion. Participants who attended religious services at least monthly were more likely to believe that 'faith alone can cure HIV' than those who attended less frequently (37.7% vs. 15.0%; P = 0.002). A small proportion (5.2%) believed that taking antiretroviral therapy implied a lack of faith in God. Bivariate analysis found no relationship between religiousness (as measured using frequency of attendance at religious services and religious attitudes or beliefs) and late diagnosis, changes in CD4 count/viral load 6 months post diagnosis, or initiation of antiretroviral therapy. ConclusionsStrong religious beliefs about faith and healing are unlikely to act as a barrier to accessing HIV testing or antiretroviral treatment for Black Africans living in London.
