Abstract
OBJECTIVES: Aimed to demonstrate the association of VC and metabolism in the obesity or overweight and determine VC changes after laparoscopic sleeve gastrectomy (LSG). METHODS: A total of 253 overweight or people with obesity were recruited, including 61 with LSG. They were divided into group A (VC < 34 ug/ml) and group B (VC ≥ 34 ug/ml). Glucose-lipid metabolic parameters were compared, and VC status before and 6 and 12 months after LSG were measured. RESULTS: (1) Body weight, body mass index (BMI), neck circumference (NC), waist circumference (WC), hip circumference (HC), waist-to-hip ratio, heart rate (HR), diastolic systolic pressure (DBP), 2-hour postprandial glucose (2h-BG), fasting insulin (FINS), 2-hour postprandial insulin (2h-INS), glycosylated hemoglobin (HBG), homeostasis model of insulin resistance (HOMA-IR), total cholesterol (TCH), triglyceride (TG) and free fatty acid (FFA) were higher while high-density lipoprotein (HDL-C) was lower in group A than group B (p < 0.05). (2) VC was negatively correlated with body weight, BMI, NC, WC and HC, HR, SBP, DBP, and 2h-BG, FINS, 2h-INS, HGB, HOMA-IR, TG and FFA, while positively with HDL-C (p < 0.05). (3) Patients with obesity or hypertriglyceridemia or low HDL-C had lower VC than corresponding group. (p < 0.05). (4) Logistic regression analysis showed that VC was the independent risk factor of hypertriglyceridemia, obesity and low HDL-C 5) VC concentrations were slightly increased in 6 months after LSG, and unchanged in 12 months after LSG. CONCLUSION: VC was closely associated with glucose-lipid metabolism, and may play a protective role in metabolic disorders. LSG would not worsen the VC status or deficiency.
