The ministry of health was interested in the relationship between office habits of workers and health issues. Each year, they distributed a survey to all workers in the public sector that contained various questions on work habits as well as a standard health questionnaire.

A health questionnaire is a list of questions about someone's health issued by underwriters before accepting a person as a risk.

Failure to volunteer full information on a health questionnaire can result in coverage being voided during a claim.

If the health questionnaire reveals that you have been treated for a certain disease, such as cancer or heart disease, the insurer may add a rider to the policy that excludes the condition.

Furthermore, health surveys can shed light on the level of healthcare the population is being offered, as well as understand health insurance coverages given to the audience. In certain cases, health surveys can be focussed to understand specific diseases or disorders by conducting longitudinal surveys or frequent surveys so as to track patterns and trends, thus allowing the survey owner to make appropriate decisions accordingly. Health surveys are an effective method to collect data from a large population or a target group.
