Description of intervention(s) / exposure
The respiratory assessment is taking place in one 3-hour visit undertaken by a research nurse.
It includes the below study procedures:
• A clinical assessment including respiratory and general medical histories, current respiratory symptoms and severity, recent respiratory events, and a clinical examination (height, weight, heart rate, breathing rate, blood pressure, listening to particpant's chest breathing and heart sounds, ear nose and throat examination)
• Assessment of lung function with spirometry
• Completing Quality of Life (St. George’s Respiratory Questionnaire and EuroQol five dimensions questionnaire) and sleep questionnaires (Epworth Sleepiness Scale Questionnaire)
• Having blood tests and chest x-ray

Outcomes
Primary outcome [1] 319419 0
Forced Expiratory Volume in 1 second (FEV1) z-score standardised for height, gender and age (ATS/ERS criteria using Global Lung Initiative reference values) as a continuous variable. The FEV1 z-score will be dichotomised to an indicator of z-score < -1.64 for the purpose of estimating population attributable risk.

Summary
Brief summary
Respiratory disease causes 69,000 hospitalisations per year in New Zealand. Pacific peoples bear the greatest burden of this disease and have much greater risk than other New Zealanders of developing different lung conditions such as asthma, bronchiectasis, bronchiolitis, pneumonia, chronic obstructive pulmonary disease and obstructive sleep apnoea. It is now thought that early childhood events affect lung growth and function in young adulthood and the risks of developing respiratory conditions. The current study is an extension of the longitudinal Pacific Islands Families (PIF) study. The purpose of the study is to examine the current respiratory health of Pacific youth at the age of 18-19 years. We will see how this compares with earlier life assessments – looking for risks but also protective effects on lung function and the presence or absence of respiratory conditions.
