What is the PIPAH Study?

The Prospective Investigation of Pesticide Applicators' Health (PIPAH) Study is the newest of the long term health studies run by the Health and Safety Executive. It was established in 2013, with the aim of investigating whether there is any evidence of a link between working with pesticides and health. The PIPAH study builds on the work of the Pesticide Users' Health Study by collecting more detailed information about the study participants. In the long term, the information from the study will help to ensure that any risks identified are properly controlled.


How do pesticide users become part of the survey?

Men and women who are certified pesticide users are eligible to join the study. The PIPAH study began in 2013, with the assistance of City & Guilds, by inviting all the members of the National Register of Sprayer Operators (NRoSO) and the National Amenity Sprayer Operators' Register (NAsOR) to take part in the study. Members of HSE's other long term health study on pesticides, the Pesticide Users' Health Study, were invited to join in 2014. The study continues to grow as new members of NRoSO and NAsOR also join.


How do we collect information about the study participants' health?

When certified pesticide users agree to take part in the study, they are asked to complete a questionnaire. This includes questions about the types of pesticides they have used, their health and other factors that can affect their health such as lifestyle, diet, smoking habit and alcohol intake. In the future, study participants will be invited to complete further questionnaires about pesticide use and particular health conditions.

In addition to this, members of the study who consented are 'flagged' with the NHS central databases through the Health and Social Care Information Centre (HSCIC). This means that the study team will be notified whenever a study member dies, is diagnosed with cancer, or emigrates from or returns to Great Britain. In this way, the long term health status of all study participants can be followed up.


How do we use the study participants' data?

The data collected by the study is used for medical research purposes only, and is kept strictly confidential. The data will be used to investigate whether there is any evidence of a link between working with pesticides and health. The PIPAH study data may also be pooled with data from similar studies in other countries, in order to study the relationships between pesticides and health for less common health conditions.

The study findings will be freely available online in Health and Safety Executive Research Reports, other published articles and in the study newsletter. The findings will be used to inform future policy.


How is the study funded?

The PIPAH study is funded by the Health and Safety Executive and by the Department for Environment, Food and Rural Affairs.
