Prevalence of Abnormal Glucose Tolerance and Risk Factors in Urban and Rural Malaysia

OBJECTIVE To determine the prevalence of prediabetes and diabetes among rural and urban Malaysians. RESEARCH DESIGN AND METHODS This cross-sectional survey was conducted among 3,879 Malaysian adults (1,335 men and 2,544 women). All subjects underwent the 75-g oral glucose tolerance test (OGTT). RESULTS The overall prevalence of prediabetes was 22.1% (30.2% in men and 69.8% in women). Isolated impaired fasting glucose (IFG) and impaired glucose tolerance (IGT) were found in 3.4 and 16.1% of the study population, respectively, whereas 2.6% of the subjects had both IFG and IGT. Based on an OGTT, the prevalence of newly diagnosed type 2 diabetes was 12.6% (31.0% in men and 69.0% in women). The prediabetic subjects also had an increased prevalence of cardiovascular disease risk factors. CONCLUSIONS The large proportion of undiagnosed cases of prediabetes and diabetes reflects the lack of public awareness of the disease.

SD 0.5). They reported inadequate time to have learners perform EPs, however (mean 2.1, SD 1.3). Inter-rater reliability on the 20 EPs showed substantial agreement for Searching (j = 0.70) and Application of Evidence (j = 0.72); moderate agreement for Overall Competence (j = 0.57) and Evaluation of Evidence (j = 0.44); and fair agreement for Question Formation (j = 0.22). Residents reported that using the EP improved their EBM skills and allowed them to apply previous EBM teaching. Both teaching staff and residents reported lack of time as a barrier to performing EPs in the inpatient setting and recommended online versions of the forms. The EP is feasible to use during inpatient rotations with modest faculty training. Inter-rater reliability was generally good, but requires further assessment. The EP can be a useful method for determining residents’ EBM competence.

Gene expression profiling in ethnic Malays with type 2 diabetes mellitus, with and without diabetic nephropathy.

BACKGROUND Diabetic nephropathy (DN) is the most common cause of end-stage renal disease (ESRD) among type 2 diabetes mellitus patients (DM) in Malaysia. This study used microarray analysis to determine the gene expression profiling in ethnic Malay patients with type 2 DM. METHODS A total of 312 patients were recruited; 25 were on dialysis due to ESRD, 128 were classified as normoalbuminuric, 93 as microalbuminuric and 66 as macroalbuminuric, based on urine albumin to creatinine ratio of <3.5, between 3.5 and 35 and =35 mg/mmol, respectively. RESULTS Microalbuminuria was associated with up- and down-regulation of 2,694 and 2,538 genes, respectively, while macroalbuminuria was associated with up-regulation of 2,520 genes and down-regulation of 2,920 genes. There was significant up-regulation of 1,135 genes and down-regulation of 908 genes in the ESRD samples. Thirty-seven significantly up-regulated genes and 40 down-regulated genes were commonly expressed in all 3 groups of patients with worsening of renal functions. Up-regulated genes included major histocompatibility complex (HLA-C), complement component 3a receptor 1 (C3AR1), solute carrier family 16, member 3 (SLC16A3) and solute carrier family 9 (sodium/hydrogen exchanger) (SLC9A8). Consistently down-regulated genes included were bone morphogenetic phosphatase kinase (BMP2K), solute carrier family 12, member 1 (SLC12A1), solute carrier family 7 (SLC7A2), paternally expressed 10 (PEG10) and protein phosphatase 1 regulatory (inhibitor unit) (PPP1R1C). CONCLUSION This study has identified several genes of interest, such as HLA-C, SLC16A3, SLC9A8, SLC12A1 and SLC7A2, that require verification of their roles as susceptibility genes for diabetic nephropathy in ethnic Malays with type 2 DM.
