This study aimed to measure the health status of a representative sample of the UK population using the EuroQoL EQ-5D questionnaire. The survey included 3,395 individuals aged 18 and over, representative of the general population in terms of age, sex, and social class. Key findings include: - One-third of respondents reported problems with pain or discomfort. - Health perceptions varied significantly based on age, social class, education, housing tenure, economic position, and smoking behavior. - The EQ-5D questionnaire effectively captures population health status and detects differences among subgroups. - Health problems increased with age, with the highest rates reported by those aged 70 and older. - Women aged 70 and older reported higher rates of problems compared to men of the same age. - Respondents with lower social classes and education levels reported more health problems. - Unemployed, sick, disabled, and retired individuals had higher rates of problems. - Renters reported more problems than owners. - Smokers reported significantly more problems than non-smokers. The study highlights the importance of including pain as a dimension in health surveys and suggests that the EQ-5D questionnaire is a practical tool for monitoring population health and detecting subgroup differences.This study aimed to measure the health status of a representative sample of the UK population using the EuroQoL EQ-5D questionnaire.
