This study aims to examine the social, economic, and behavioral characteristics of HIV patients in East London. The research focuses on ethnicity, gender, sexuality, education, employment, housing, HIV treatment, stigma, discrimination, religion, migration, and sexual risk behavior. The study involved 2680 HIV patients attending outpatient clinics at six hospitals in East London over a 4-6 month period in 2004-2005. Of these, 2299 were eligible and 1687 completed the questionnaire, resulting in a 73% response rate. The data collected will provide valuable information for planning and delivering appropriate clinical care, social support, and health promotion for people living with HIV in East London and elsewhere in the UK. East London has a diverse population, with a higher proportion of black African patients compared to other parts of the capital. The study found that nearly 90% of the sample consisted of gay/bisexual men and black African heterosexual men and women, who are the groups most affected by HIV in the UK. The study also highlights the importance of understanding the social and behavioral factors that contribute to HIV transmission, including socioeconomic disadvantage, ethnicity, and migration patterns. The findings from this study will help inform public health strategies and interventions for HIV prevention and care in East London and beyond.This study aims to examine the social, economic, and behavioral characteristics of HIV patients in East London.
