Autoantibody Screening in Sibling-Dominant Pediatric Relatives of Type 1 Diabetes Patients: Prevalence, Determinants, and Psychological Impact

MedXY Editorial Team•Sep 6, 2026•Diabetes & Endocrinology

In a sibling-dominant cohort of 440 Turkish children (2-18 years) first-degree relatives of type 1 diabetes patients, 16.4% tested positive for pancreatic islet autoantibodies, with ZnT8A being the most prevalent, especially in early childhood (ages 2-6).
Gestational age showed a strong inverse association with autoantibody positivity, suggesting perinatal factors influence risk stratification.
Disclosure of autoantibody screening results significantly increased child anxiety scores and parental state and trait anxiety in positive cases, while anxiety decreased in negative cases.
The findings advocate for personalized presymptomatic risk assessment incorporating age and perinatal history, coupled with structured psychological support integrated into screening programs.
