Insulin Levels, BMI in Youth May Be Linked to Psychosis, Depression Risk in Adulthood

Disrupted insulin sensitivity in childhood and adolescence may be a shared risk factor for cardiometabolic disorders and psychosis in adulthood, astudy inJAMA Psychiatry has found. The study also found that a major increase in BMI around puberty may indicate a greater risk for adult depression.Benjamin I. Perry, M.R.C.Psych., of the University of Cambridge School of Clinical Medicine in Cambridge, United Kingdom, and colleagues examined data from people aged 1 to 24 years in the Avon Longitudinal Study of Parents and Children, a prospective study of approximately 15,000 British people. They obtained data on fasting insulin levels for 5,790 people measured at ages 9, 15, 18, and 24 years, and BMI for 10,463 people measured at 1, 2, 3, 4, 7, 9, 10, 11, 12, 15, 18, and 24 years.Those with persistently high fasting insulin levels from age 9 years had five times the odds of psychosis and 3.22 times the odds of having a psychotic disorder at age 24. However, fasting insulin levels were not associated with depression.“Our findings complement meta-analyses reporting altered glucose-insulin homeostasis in first-episode psychosis. Moreover, our results suggest that disruptions to glucose-insulin homeostasis detectable at first-episode psychosis in adults may begin in childhood,” Perry and colleagues wrote. Alte red glucose-insulin homeostasis could be a shared mechanism for psychosis and type 2 diabetes, they added.People who experienced a major increase in BMI as they entered pube...
