Aims: Individuals with intellectual developmental disabilities (IDD) face unique challenges in managing type 2 diabetes mellitus (T2DM), but evidence on their impact on mortality is limited. This study assessed the association between IDD and mortality in T2DM using nationwide Korean data.
Methods: A retrospective cohort of 2,522,244 individuals with T2DM who underwent health screenings through the Korea National Health Insurance Service 2015-2016 was analyzed. IDD presence and severity were evaluated, and mortality risks were estimated using multivariable Cox proportional hazards models.
Results: Among a total population, 0.22 % (n = 5,627) had IDD. Over a six-year median follow-up, 201,153 deaths (7.98 %) occurred. Individuals with IDD had significantly higher risk of all-cause mortality (hazard ratio [HR] 3.40, 95 % CI: 3.14-3.68), with greater severity correlating with higher risk (P < 0.001). Cause-specific mortality risks were significantly elevated for cardiovascular (HR 3.77, 95 % CI: 3.12-4.55), cancer (HR 1.52, 95 % CI: 1.24-1.86), and respiratory diseases (HR 7.71, 95 % CI: 6.27-9.48). Younger individuals showed stronger associations.
Conclusions: Individuals with T2DM and IDD, particularly those with severe IDD, have a significantly higher mortality risk. Tailored healthcare strategies and enhanced social support are urgently required to reduce disparities in this vulnerable population.

Aim: Early identification of limited intellectual functioning is important for providing support. This study investigated whether a universal child development score (D-score) at 12, 24 and 36 months can predict limited intellectual functioning at 5-10 years of age, in addition to neonatal and parental characteristics.
Methods: A case-control study using developmental milestones and health records from three Dutch child healthcare organisations.

Introduction: There is a gap between individuals with intellectual and developmental disabilities (IDD) who need treatment for self-injurious behavior (SIB) and those who receive it. One contributing factor may be a multiplicity of beliefs about the nature of SIB and its treatment.
Methods: Using reflexive thematic analysis, we interviewed and integrated two knowledge sources: the perspectives of family caregivers for individuals with SIB and IDD and the perspectives of clinicians and researchers who treat and study self-injury.

ObjectivesTo (1) understand the challenges and benefits of providing pregnancy care to people with disabilities and (2) identify strategies to address challenges, from the perspectives of health care and social service providers and decision-makers.MethodsWe undertook a qualitative descriptive study in Ontario, Canada, of 31 health care and social service providers and decision-makers. Participants completed semi-structured interviews about their education, training, and clinical or administrative experience working with pregnant and/or parenting people with physical, sensory, and intellectual or developmental disabilities, including challenges and benefits in pregnancy care provision, programming, and policies, as well as their recommendations to improve care.
