The Health & Lifestyle Questionnaire (HLQ) was launched in 2014 to better describe TRA membership through the publication of summary statistics to both the twin and the researcher communities.
The HLQ enables identification of potential participants for specific research studies to reduce costs to researchers and unnecessary approaches to ineligible TRA members. It also enhances fast-track research by providing de-identified data to researchers for ethically approved research analyses.
The questionnaire contained demographic questions and covered a broad range of health conditions and risk factors.
• Income, employment
• General health, medical conditions, lifestyle
• Screening for breast, colon and prostate cancer
