NCT02929953

Brief Summary

The aims of this study are:

  1. 1.To assess the prevalence of prematurity, especially early prematurity, among T1D patients, and compare it to the prematurity prevalence among the non-diabetic general population in Israel.
  2. 2.To characterize epidemiological and clinical factors that differ between premature-born patients that developed T1D and those that have not, including the nutritional and therapeutic properties in NICU.

Sampling MethodNon-Probability Sample
Study Population

All T1D patients in Israel, born during 1990-2013 and diagnosed prior to January 2015, time of data collection. Inclusion criteria included all patients diagnosed as T1D by a pediatric endocrinologist according to the American Diabetes Association criteria, and treated for their T1D with insulin. Patients are identified from registries of the 13 participating centers.

You may qualify if:

  • Patients diagnosed with T1D
  • Patients treated in one of the 13 participating centers
  • For the case-control portion of the study, all children born between 1.1.1990-31.12.2013 and admitted to NICU medical centers that have been included in the original cohort portion
  • Patients for whom a complete medical record is available

You may not qualify if:

  • Lack of birth data
  • Unknown type of diabetes
  • For case control portion, an incomplete medical record/inadequate documentation
