Brief Summary
The purpose of the HAPI project is to study the overall health of preterm infants once they reach adulthood. The investigators would like to compare the health of adults born preterm with that of adults born full-term. They would also like to find the early signs, or biomarkers, of chronic diseases such as high blood pressure, diabetes, osteoporosis, and chronic lung diseases. Such biomarkers would allow for early diagnosis and prevention. Furthermore, the investigators would like to understand why some people born preterm are more likely to develop chronic disease. They believe that inflammation and oxidative stress may play a part. Oxidative stress is present when the body is not able to defend itself against oxygen-derived products that can damage our cells. To carry out this study, the investigators will examine 6 aspects of the health: (1) heart and circulation, (2) kidneys, (3) lungs, (4) metabolism - sugars and fats in the blood, (5) bones, and (6) eyes.

Outcome Measures
Primary Outcomes (4)
Markers of inflammation
Blood samples for measurements of biomarkers of inflammation are collected in the morning the day of the visit. Monocyte chemoattractant-1 (pg/mL), Interleukine-6 (pg/mL), tumor necrosis factor-alpha (pg/mL), intercellular adhesion molecule-1 (pg/mL), vascular cell adhesion molecule-1 (pg/mL), high-sensitivity C-reactive protein (pg/mL).
1 hour
Markers of oxydative stress in the blood
Blood samples for measurements of biomarkers of oxidative stress are collected in the morning the day of the visit. Blood : Glutathione (GSH and GSSG (nmol/mg of proteins)) and Redox potential using the Nernst equation and the values of GSH and GSSG (mV).
1 hour
Markers of oxydative stress in the urine
Urine 8-prostaglandin F2-alpha (pg/mL).
1 hour
Markers of oxydative stress in the plasma
Oxidized LDL (U/L)

Study Arms (2)
Extremely preterm (EPT)
All adults born at gestational age (GA) \<29 wks at CHU Sainte-Justine (CHUSJ), the Royal Victoria Hospital (RVH), and the Jewish General Hospital (JGH), Montreal, in 1987-97. Inclusion criteria: (a) Birth at GA\<29 wks, (b) age 18-29 years at the time of assessment (age of peak human physiological function). Exclusion criteria: (a) currently pregnant due to X-ray related risks, (b) severe neurosensory deficit preventing test completion. In case of twins (or +), if both fulfil inclusion criteria, only one will selected (random) to participate to the study.
Term or controls
Same-sex friends identified by EPT subject who have accepted to be contacted. Inclusion criteria: (a) Birth at GA ≥37 wks, (b) born in Quebec, to account for health care access during pregnancy and throughout infancy/childhood, (c) birth date within 2 years of index case, (d) age 18-29 years at the time of assessment, (e) same self-reported race as preterm participant. Exclusion criteria: (a) currently pregnant due to X-ray related risks, (b) severe neurosensory deficit preventing test completion.
Interventions
The study compares young adult subjects born premature (\< 29 weeks) versus term (-\> 37 weeks)
Eligibility Criteria
All adults born at GA\<29 wks at CHU Sainte-Justine, the Royal Victoria Hospital, and the Jewish General Hospital, Montreal, in 1987-97. For each EPT subject, a friend control matched on sex is selected to control in part for lifestyle and social factors (e.g. diet, physical activity, health care visits), and environmental exposure that may affect inflammatory status and disease risk. Indeed, given the known link between lower socio-economic status, lifestyle habits and CVD risk factors, and that women from lower SES and with poor lifestyle behaviors are at increased risk to deliver prematurely, a friend control, who is more likely to have evolved in a similar milieu, will allow us to better isolate the effect of preterm birth on studied outcomes from socio-environmental factors.
You may qualify if:
- EPT :
- Birth at GA\<29 wks
- Age 18-29 years at the time of assessment (age of peak human physiological function)
- Terms:
- Birth at GA ≥37 wks
- Born in Quebec, to account for health care access during pregnancy and throughout infancy/childhood
- Birth date within 2 years of index case
- Age 18-29 years at the time of assessment
- Same self-reported race as preterm participant.
You may not qualify if:
- Both groups :
- Currently pregnant due to X-ray related risks
- Severe neurosensory deficit preventing test completion.
