Swedish children with Type 1 diabetes (T1D) show a doubled mortality risk compared to the general population. This increased risk, particularly for males, persists despite good healthcare access, highlighting ongoing challenges in T1D management.

Area of Science:

  • Pediatrics
  • Endocrinology
  • Public Health

Background:

  • Type 1 diabetes (T1D) management and outcomes in pediatric populations are critical public health concerns.
  • Sweden maintains a comprehensive national registry for newly diagnosed T1D cases in children since 1977.

Purpose of the Study:

  • To assess the short-term mortality rates and causes of death in Swedish children diagnosed with Type 1 diabetes.
  • To compare the mortality risk in this pediatric T1D cohort with the general Swedish population.

Main Methods:

  • Analysis of a national Swedish registry data for children (0-14 years) diagnosed with T1D between July 1, 1977, and December 31, 1985.
  • Calculation of overall mortality rates and standardized mortality ratios (SMR) by sex.
  • Review of causes of death for registered patients.

Main Results:

  • Ten deaths (0.75 per 1000 patient-years) occurred among 3228 registered children with T1D.
  • The overall standardized mortality ratio (SMR) was 2.09 for both sexes combined, indicating a 2.09-fold increased mortality risk compared to the general population.
  • Mortality risk was significantly elevated for males (SMR = 2.61) but not for females.
  • Five deaths were attributed to diabetes, while the other five were due to accidents, other diseases, or were uncertain.

Conclusions:

  • Despite a relatively low mortality rate compared to previous studies, short-term mortality remains significantly elevated in Swedish children with Type 1 diabetes.
  • The increased mortality risk, especially in males, persists even in a setting with excellent socioeconomic status, patient education, and free healthcare access.
  • These findings underscore the need for continued efforts to improve T1D management and reduce mortality in pediatric patients.
