OBJECTIVE: Better understanding of the temporal development of cardiovascular risk will permit more targeted prevention of premature cardiovascular mortality in schizophrenia. METHODS: The sample for this analysis was drawn from referrals (between 2006 and '11) to an early psychosis clinic based in a U.S. urban community mental health center. 76 individuals with schizophrenia who were young (mean 22.4 years, SD 4.8), early course (median duration of illness 31 weeks) and with minimal prior antipsychotic exposure (median 2 weeks) were compared to age-, gender-, and race-matched peers drawn from the National Health and Nutrition Survey (2007-'08). Measures of cardiovascular risk at baseline, 6 months, and 1 year are reported. RESULTS: While indistinguishable from peers at entry, patients suffered pervasive adverse trajectories of cardiovascular risk factors over the subsequent year. 16 of 44 initial non-smokers became nicotine dependent and none of 32 entering smokers quit. 17 patients transitioned to overweight (BMI 25-29.9, n = 3) or obese (BMI>30, n = 14) categories, while only 24 of 38 (63%) sustained normal weight over one year. Similar adverse trends in blood pressure, lipids, and fasting glucose led to an increase in prevalence of metabolic syndrome (1.31% to 5.26%). 10-year cardiovascular risk estimates showed a small and significant increase although remaining in the low risk (<10%) category. CONCLUSIONS: The early emergence of obesity and smoking in younger schizophrenia samples provides a rational focus for primary prevention of premature cardiovascular mortality. The first year of treatment constitutes the beginning of a critical period for such preventive efforts.
