The Health Survey combines questionnaire answers and physical measurements as well as other objective measures such as analysis of blood samples, ecg readings and lung function tests.
The Health Survey for England contains a 'core' which is repeated each year and each survey year has one or more modules on subjects of special interest.
The 'core' includes:
- questions on general health and psycho-social indicators
- demographic and socio-economic indicators
- questions about use of health services and prescribed medicines - the focus for these may vary from year to year to suit the modular content of the survey.
- blood pressure
- measurements of height, weight and blood pressure
The modules may be about a single topic, several topics or about population groups. The following years included the following modules:
- 1993 cardiovascular disease
