ABSTRACT
Type 1 diabetes mellitus (T1DM) is a common chronic disease in children and young people. Living with diabetes can pose many challenges both medical and psychological. Disordered eating behaviours, intentional insulin omission and recognised eating disorders are common among young people with diabetes and are associated with increased risk of short-term and long-term complications and death. Recognition of these behaviours is important to ensure that relevant support is provided. Joint working between diabetes and mental health teams has challenges but is essential to ensure all needs are met during treatment and recovery.

OBJECTIVE: Thyroid dysfunction is associated with impaired cognitive development. Perchlorate decreases thyroidal iodine uptake, potentially reducing thyroid hormone production. It is unclear whether perchlorate exposure in early life affects neurodevelopment. DESIGN: Historical cohort analysis. PATIENTS: From 2002 to 2006, 21,846 women at gestational age <16 weeks recruited from antenatal clinics in Cardiff, UK and Turin, Italy were enrolled in the Controlled Antenatal Thyroid Screening Study (CATS). We undertook a retrospective analysis of 487 mother-child pairs in mothers who were hypothyroid/hypothyroxinemic during pregnancy and analyzed whether first trimester maternal perchlorate levels in the highest 10% of the study population were associated with increased odds of offspring IQ being in the lowest 10% at 3 years of age. MAIN OUTCOME MEASURES: Maternal urinary perchlorate, offspring IQ. RESULTS: Urine perchlorate was detectable in all women (median 2.58 µg/L); iodine levels were low (median 72 µg/L). Maternal perchlorate levels in the highest 10% of the population increased the odds of offspring IQ being in the lowest 10% OR = 3.14 (95% CI 1.38, 7.13) P = .006 with a greater negative impact observed on verbal OR = 3.14 (95% CI 1.42, 6.90) P = .005 than performance IQ. Maternal levothyroxine therapy did not reduce the negative impact of perchlorate on offspring IQ. CONCLUSIONS: This is the first study using individual-level patient data to study maternal perchlorate exposure and offspring neurodevelopment and suggests that high-end maternal perchlorate levels in hypothyroid/hypothyroxinemic pregnant women have an adverse effect on offspring cognitive development, not affected by maternal levothyroxine therapy. These results require replication in additional studies, including in the euthyroid population.
