The Metabolic Syndrome Is Associated with Reduced Central Serotonergic Responsivity in Healthy Community Volunteers
Abstract
CONTEXT: The pathobiology of the metabolic syndrome remains unclear. The central nervous system is likely to be involved via regulation of eating, physical activity, blood pressure, and metabolism. OBJECTIVE: The objective of this study was to test the hypothesis that low central serotonergic activity is associated with the metabolic syndrome. DESIGN, SETTING, PARTICIPANTS: This was a cross-sectional study of 345 healthy community volunteers, aged 30-55 yr, not taking medications for hypertension, lipid disorders, or diabetes. OUTCOME MEASURES: Central serotonergic responsivity was assessed with the iv citalopram challenge test. The serum prolactin area under the curve (AUC) over 150 min was calculated, and all analyses were adjusted for age, sex, plasma citalopram concentration, and baseline prolactin. The metabolic syndrome was defined according to the National Cholesterol Education Program (NCEP) and International Diabetes Federation (IDF) criteria. Insulin resistance was estimated by homeostasis model assessment. RESULTS: Compared with other individuals, persons meeting either NCEP or IDF criteria for the metabolic syndrome had lower mean prolactin responses (P < 0.05 for both). Using logistic regression, a decrease in prolactin AUC of 1 sd (-13.6 ng/ml.h) more than doubled the odds of having the metabolic syndrome (NCEP criteria: odds ratio, 2.38; 95% confidence interval, 1.14-4.97; P = 0.02; IDF criteria: odds ratio, 2.80; 95% confidence interval, 1.48-5.30; P = 0.002). Finally, the prolactin AUC was negatively associated with insulin resistance (beta = -0.03, P = 0.02). CONCLUSIONS: Corroborating previous evidence, the metabolic syndrome was associated with diminished brain serotonergic activity as reflected in a comparative blunting of the prolactin response to a selective serotonergic challenge. This association may have implications for the etiology, prevention, and treatment of the metabolic syndrome.

In the citing paper
“A biologically plausible shared antecedent is diminished central serotonergic function. Reduced serotonin availability has been linked to increased appetite and weight gain, central adiposity, impaired glucose tolerance, and insulin resistance, alongside depressed mood (88).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
