Longitudinal Preterm Outcome Project (LOLLIPOP)
LOLLIPOP was a community-based study on the growth and development of preterm and full-term children born in the Netherlands in 2002 and 2003. The study recruited children before their regular well-child visit, typically between the ages of three and four years. After every two preterm-born children, one full-term child was included as a control. In total, the cohort included over 1,800 preterm children and 700 full-term children, along with their parents. Data was collected from external sources, such as medical records, and participants were assessed at ages 4, 5, 7 and 13 to 14 years.
