Abstract
CONTEXT AND OBJECTIVE: In this prospective study, we evaluated the association of retinoic acid (RA) with the metabolic syndrome (MetS) in the Chinese population. DESIGN AND PARTICIPANTS: A total of 1042 nondiabetic adults from the population-based Nutrition and Health of Aging Population were prospectively followed up for 4 years. Serum RA concentrations was determined and its relationship with the MetS and its component was investigated. RESULTS: At baseline, higher RA levels were inversely associated with the presence of MetS (odds ratio 0.61; 95% confidence interval [CI] 0.44–0.74, P < .001) after adjustment for age, gender, body mass index, the homeostasis model assessment index for insulin resistance (HOMA-IR), and other confounding factors. Subjects with lower RA levels had a progressively worse cardiometabolic risk profile at baseline. Serum RA levels were inversely associated with 8-iso-prostaglandin F2α (P < .001), high-sensitivity C-reactive protein (P = .015), and IL-6 (P = .020) and positively correlated with high-density lipoprotein cholesterol (P = .038). Among 825 subjects without MetS at baseline, 146 had developed it at 4 years. Serum RA by quartiles was inversely correlated with the incident MetS (adjusted hazard ratio 0.67; 95% CI 0.48–0.81, P = .006). Apart from HOMA-IR (P < .001), the baseline RA level was the only independent predictor of the development of the MetS during the 4-year follow-up (odds ratio 0.53; 95% CI 0.40–0.69; P < .001) after adjustment for age, gender, body mass index, and HOMA-IR. CONCLUSIONS: The serum RA level is inversely associated with the development of MetS independently of adiposity and insulin resistance.
