[A survey of glucose and lipid metabolism and concomitant diseases among inpatients in Guangdong province].Zhonghua Nei Ke Za Zhi. 2009 Mar; 48(3):196-200.ZN
To investigate the epidemiological and clinical characteristics of dyslipidemia as well as its treatment and influence on accompanying diseases in impaired glucose status among inpatients.
A cross-sectional survey was conducted among the inpatients registered in ten university hospitals of Guangdong, China during the week before the Diabetes Day in 2004. The fasting blood glucose (FBG), lipid profiles, BMI, waist to hip ratio (WHR) and concomitant disorders of the first screen during the hospitalization period were recorded. Those who had FBG level from 5.6 to 6.9 mmol/L and not been previously diagnosed diabetes (PDM) underwent oral glucose tolerance test (OGTT).
Of the 8753 inpatients investigated, 1067 cases had complete medical records (CMR case) including PDM cases and previously non-diagnosed diabetes ones with FBG > or = 5.6 mmol/L. Of the previously non-diagnosed diabetes cases with FBG levels from 5.6 to 6.9 mmol/L, 65.8% accepted OGTT. Of the CMR cases, 41.9% had PDM, 21.7% was newly diagnosed diabetes mellitus (NDM), 29.1% had impaired glucose regulation (IGR) and only 7.3% had normal glucose tolerance (NGT). The TG levels in NDM and PDM group were higher than those in IGR and NGT group (P < 0.05, respectively). The HDL-C levels in IGR, NDM and PDM group were lower than those in NGT group (P < 0.05, respectively). Sixty-nine point six percent of the diabetes mellitus (DM) inpatients was accompanied with dyslipidemia and the rate was higher than those in NGT (56.4%) and IGR inpatients (52.5%, P < 0.05, respectively). Only 22.8% of the PDM inpatients underwent treatment of dyslipidaemia and just 3.4% achieved the target suggested by the guideline of ATP-III. BMI was higher and waistline longer in the PDM and NDM inpatients than those in the NGT cases (P < 0.05, respectively). Seventy-two point eight percent of the PDM inpatients was complicated with more than one type of vascular diseases. Nine point seven percent and 0.2% of the NDM inpatients were tormented by diabetic nephropathy and diabetic retinopathy respectively.
More inpatients with accompany DM or IGR had concomitant dyslipidemia than those with NGT, which included hypertriglyceridemia, hypo-high-density lipoproteinemia and metabolic syndrome. Concomitant vascular diseases were more frequently found in PDM inpatients than in the others. Some of the NDM and IGT inpatients were complicated with microvascular diseases.
