The prevalence of type 2 diabetes is escalating rapidly in Asian countries, with the rapid increase likely attributable to a combination of genetic and lifestyle factors. Recent research suggests that common genetic risk variants contribute minimally to the rapidly rising prevalence. Rather, recent changes in dietary patterns and physical activity may be more important. This nested case-control study assessed the association and predictive utility of type 2 diabetes lifestyle risk factors in participants from Malaysia, an understudied Asian population with comparatively high disease prevalence. The study sample comprised 4077 participants from The Malaysian Cohort project and included sub-samples from the three major ancestral groups: Malay (n = 1323), Chinese (n = 1344) and Indian (n = 1410). Association of lifestyle factors with type 2 diabetes was assessed within and across ancestral groups using logistic regression. Predictive utility was quantified and compared between groups using the Area Under the Receiver-Operating Characteristic Curve (AUC). In predictive models including age, gender, waist-to-hip ratio, physical activity, location, family history of diabetes and average sleep duration, the AUC ranged from 0.76 to 0.85 across groups and was significantly higher in Chinese than Malays or Indians, likely reflecting anthropometric differences. This study suggests that obesity, advancing age, a family history of diabetes and living in a rural area are important drivers of the escalating prevalence of type 2 diabetes in Malaysia.

Introduction Type 2 diabetes mellitus is a common multifactorial genetic syndrome, which is determined by several genes and environmental factors. The aim of the present study was to investigate the presence of risk factors for developing diabetes type 2 among diabetic individuals and to compare the presence of risk factors among diabetic individuals with and without positive family history for type 2 diabetes. Material and methods This study was conducted in Cuprija during the period from February to June 2002. The case group included 137 individuals having diagnosis type 2 diabetes. The control group included 129 subjects having the following diagnoses: hypertension, angina pectoris, chronic obstructive lung disease, gastric ulcer or duodenal ulcer. All participants were interviewed at the Medical Center Cuprija using structural questionnaire. The data were collected regarding demographic characteristics, exposure to various chemical and physical agents, stress, smoking, obesity, physical inactivity and family history of diabetes. In the statistical analysis chi square test was used. Results The diabetic individuals were statistically significantly older (40 and more years old) (p=0,000), and they came from rural areas more frequently (p=0,006) than the individuals without diabetes. Significantly more diabetics had lower educational level (p=0,000) and they were agriculture workers and housewives significantly more frequently (p=0,000) than nondiabetic individuals. Furthermore, obesity (p=0,000) and physical inactivity (p=0,003) were significantly more frequent among the diabetic individuals than the nondiabetics. The diabetic individuals had significanly (p=0,000) more numbers of relatives with diabetes mellitus type 2 than the nondiabetics. The diabetic individuals with positive family history of diabetes were significantly older (p=0,021) and more frequently from urban areas (p=0,018) than the diabetic individuals without the positive family history of diabetes. Also they were significantly less exposed to physical agents (p=0,004). Discussion In our study, like in many others, age, place of residence, education, occupation, obesity, physical inactivity, positive family history of diabetes type 2 and exposure to physical agents were identified as potential risk factors for diabetes type 2. Conclusion Different risk factors are probably responsible for developing type 2 diabetes among individuals with and without positive family history of type 2 diabetes.

This cross-sectional study sought to describe an association between family history of type-2 diabetes and the awareness of risk factors, perceived threat and physical activity levels in African Americans. With a prevalence of 11.8%, African Americans remain disproportionately affected by the epidemic of diabetes. A risk factor that cannot be modified, but is important and closely linked with diabetes expression, family history, can be a considerable tool in promoting behavior change and reducing the risk of developing the condition in African Americans. A self-report questionnaire was administered to 133 church going African Americans, with 55 of them with a positive family history of type-2 diabetes (41.4%) and 78 (58.6%) without. None of the participants had been previously been diagnosed with type-2 diabetes. The results from the study indicated that African Americans with positive family history had a greater knowledge of risk factors, were more likely to indicate that their concern about the disease influences their eating habits and physical activity, and engaged in significantly more physical activity than those with no family history.

The E23K variant of the Kir6.2 gene has been shown to be associated with type 2 diabetes mellitus in Caucasian subjects. Because offspring of type 2 diabetic patients have a genetically increased risk of developing diabetes, we sought to identify the E23K variant of the Kir6.2 gene in offspring of Caribbean patients with type 2 diabetes and assess the contribution of this variant to impaired glucose tolerance in these subjects. Forty-six offspring of patients with type 2 diabetes and 39 apparently healthy subjects whose immediate parents were not diabetic (‘control’) were studied after an overnight fast. Anthropometric indices were measured and blood samples were collected. Fasting and 2 h plasma glucose, insulin and lipids were subsequently determined. Insulin resistance was calculated using the homeostatic model assessment technique. The offspring and control subjects had similar frequencies of the E23K polymorphism (52.6 vs 45.5%, P>0.05) and the frequency of the E23K variant did not differ significantly between gender and ethnic distributions, irrespectively of a family history of diabetes (P>0.05). There were no significant differences in biochemical risk factors for developing diabetes in offspring carriers of the E23K variant compared with offspring non-carriers of the mutation. Offspring with the E23K mutation had even significantly higher 2 h insulin concentrations when compared with control subjects. It is concluded that the presence of the Kir6.2 E23K genotype in Caribbean subjects with an immediate positive family history of diabetes does not confer significantly higher levels of biochemical risk factors for the development of type 2 diabetes.

BACKGROUND: Diabetes is the leading cause of morbidity and mortality amongst the people of Pakistan. In 2015, 7 million people had diabetes and the number is still on raise. Family history of diabetes, high body mass index, and other sociodemographic factors are the risk factors of diabetes. Persistent exposure to excessive glucose may be a reason behind diabetic complications like nephropathy, neuropathy, retinopathy, cardiomyopathy and gestational diabetes mellitus.METHODS: For the evaluation of laboratory parameters, 600 blood samples were collected at Akhuwat Diabetic Centre and from Jinnah Hospital, Lahore. Demographic data of the participants was collected by filling a questionnaire. Lipid profile, liver enzymes, and renal function tests were performed and statistical analysis was done.RESULTS: Type 2 diabetes mellitus among other types is the most prevalent form of diabetes in our population. Family history of diabetes (p=0.002), Body Mass Index (>25) p<0.001, high cholesterol (p=0.04), high triglyceride p<0.001, high LDL p<0.001 and low HDL p<0.001 are significantly associated with the incidence of diabetes. Hypertension among the other comorbidities is more common in diabetic patients.CONCLUSION: Type 2 Diabetes Mellitus is highly prevalent in the local population. Improved lifestyle and proper medical monitoring can help to manage diabetes in our population.

Type 2 diabetes mellitus is reaching epidemic proportions among children and adolescents. School health fairs offer an opportunity to identify children with risk factors for the development of type 2 diabetes mellitus. This study identified selected risk factors (i.e., high-risk racial/ethnic group, obesity, elevated blood pressure, elevated casual blood glucose, elevated total cholesterol, and the presence of acanthosis nigricans) for development of type 2 diabetes mellitus in rural children with or without a family history of diabetes during annual school health fairs. Of the children screened, 40% (673) presented with two or more of the identified risk factors for type 2 diabetes mellitus. The presence of multiple risk factors in participants reporting a positive family history of diabetes mellitus versus those with no family history was not statistically significant. Based on the study results, factors other than family history may be more predictive for the development of type 2 diabetes mellitus in rural school children.

Aim: This study evaluated the prevalence of prediabetes and type 2 diabetes mellitus in the Gwalior-Chambal region of India. Methods: A cross-sectional house-to-house survey was conducted on a population of 7608 subjects, aged between 20 and 79 years for fasting blood glucose level in finger-prick blood. Participants were stratified based on blood glucose levels, gender, age, family history, etc. to assess their impact. Result: The prevalence of type 2 diabetes and prediabetes in the Gwalior-Chambal region was found to be 11.4% and 5.7%, respectively. The prevalence of diabetes was significantly higher in the urban population (12.7%) while that of prediabetes was higher in the rural population (7.9%). Male subjects recorded a higher prevalence of prediabetes (8.2%, OR 1.54 in rural; 5.1%, OR 1.26 in urban) as well as diabetes (rural 9.2%, OR 3.15; urban 16.5%, OR 1.57). Both prediabetes and diabetes were recorded as being higher in those subjects leading a sedentary lifestyle and in the aged population. The prevalence of hyperglycemia was much higher in those with a family history of type 2 diabetes (30.6% in rural, 21.5% in urban). Almost half of the diabetics in the rural population were diagnosed for the first time. The multivariate regression analysis identified male gender, increasing age of 30 years and above, and positive family history as significant risk factors for diabetes whereas age of 40 to 79 and less physical activity were significant risk factors for prediabetes. Conclusion: Family history of diabetes, and sedentary lifestyle appeared as key factors promoting prediabetes and diabetes in the Gwalior-Chambal region. A lack of awareness appeared as one of the major causes of the high prevalence in the rural region.

Background: The prevalence of Type 2 diabetes mellitus (T2 DM) in children and adolescents is on the increase, therefore, prevention and early detection are important.Objective: To assess for easily identifiable risk factors (overweight/obesity, hypertension, Impaired Fasting Glucose (IFG) and family history of diabetes) for T2DM in adolescents in public secondary schoolsResult: Eight hundred and eighty adolescents aged 10 to 19 years were screened and 124(14.1%) were overweight/obese. 457 (51.9%) of students had none of the risk factors while 272(30.9%) had at least one risk factor. Using the American Diabetes Association criteria for identification of those at risk for T2DM, 21(2.4%) were identified. The frequency of presence of risk factors was more in females (3.3%), mid adolescent age group (3.1%) and those with positive family history of diabetes. These findings were however not statistically significant. There was a statistically significant association between presence of hypertension and impaired fasting glucose and risk factor for type 2 DM.Conclusion: The significant risk factors identified in this study were prehypertension/hypertension and impaired fasting blood glucose.Key words: Adolescence, Risk factors, Type 2 diabetes mellitus

Diabetes type 2 (T2D) had caused the loss of millions of lives all over the world. About 50% of the patients with T2D die because of cardiovascular disease (CVD), primarily myocardial infarction and stroke. Many of the leading risk factors for CVD coexist and act synergistically to increase cardiovascular events. The purpose of this descriptive cross-sectional study was to determine the prevalence, patterns, and certain predictive factors in the complications of T2D patients attending diabetic clinics at Mnazi Mmoja hospital. A total of 138 respondents made up of 58 females and 80 males within the age brackets of 30-40, 41-50, 51 – 60, and 61 above were recruited for this study. Data were analysed and interpreted based on certain predictive factors and variables, including smoking, alcohol, excessive salt intake, lipid intake, sedentary lifestyle, family history of diabetes, and hypertension, on how they relate to the development of complications of type 2 diabetes. Pearson Chi-Square test was used to compare the levels of significances. Probability values of less or equal to 0.05 were accepted to be significant. The combination of salt intake, sedentary lifestyle, family history of diabetes, and lipid intake was the commonest risk factor for developing complications of T2D. However, alcohol and cigarette smoking had the most negligible impact on developing complications in T2D. The result also shows the patients between the age bracket of 30 and 40 have more risk factors for developing complications. The result showed no gender difference in the number of risk factors. There was a statistically significant association between some of the risk factors (smoking, alcohol, sedentary lifestyle, and salt intake) and the gender of respondents (p<0.05). Males smoked (43.8%) and consumed alcohol (32.5%) than females, while females were prone to a sedentary lifestyle (63.8%) and consume salt (82.8%) than males. On the other hand, this research showed that the significant complication for both males and females are numbness, pain sensation, and dry skin (diabetic neuropathy). Gender and certain predictive risk factors like salt intake, sedentary lifestyle, and family history of diabetes, and lipid intake are fundamental parameters to be tackled to reduce the complications of type 2 diabetes mellitus. There is a greater need now for awareness of the risk factors through effective health promotion in Zanzibar. Also, secondary prevention through regular screening, early detection, and appropriate treatment of chronic complications could reduce the morbidity and mortality caused by diabetes mellitus.

IntroductionWe sought to investigate the relationship between serum 25-hydroxyvitamin D (25(OH)D) level and the risk of type 2 diabetes mellitus (T2DM) in adults who participated in the Trøndelag Health Study (HUNT), and the possible effect modification by family history and genetic predisposition.Research design and methodsThis prospective study included 3574 diabetes-free adults at baseline who participated in the HUNT2 (1995–1997) and HUNT3 (2006–2008) surveys. Serum 25(OH)D levels were determined at baseline and classified as <50 and ≥50 nmol/L. Family history of diabetes was defined as self-reported diabetes among parents and siblings. A Polygenic Risk Score (PRS) for T2DM based on 166 single-nucleotide polymorphisms was generated. Incident T2DM was defined by self-report and/or non-fasting glucose levels greater than 11 mmol/L and serum glutamic acid decarboxylase antibody level of <0.08 antibody index at the follow-up. Multivariable logistic regression models were applied to calculate adjusted ORs with 95% CIs. Effect modification by family history or PRS was assessed by likelihood ratio test (LRT).ResultsOver 11 years of follow-up, 92 (2.6%) participants developed T2DM. A higher risk of incident T2DM was observed in participants with serum 25(OH)D level of<50 nmol/L compared with those of ≥50 nmol/L (OR 1.72, 95% CI 1.03 to 2.86). Level of 25(OH)D<50 nmol/L was associated with an increased risk of T2DM in adults without family history of diabetes (OR 3.87, 95% CI 1.62 to 9.24) but not in those with a family history (OR 0.72, 95% CI 0.32 to 1.62, p value for LRT=0.003). There was no effect modification by PRS (p value for LRT>0.23).ConclusionSerum 25(OH)D<50 nmol/L was associated with an increased risk of T2DM in Norwegian adults. The inverse association was modified by family history of diabetes but not by genetic predisposition to T2DM.

Abstract Objective MicroRNAs are known to regulate 60% of genes at post translational level. MicroRNAs including Micro RNA-29 family play a vital role in cellular activities and have validate role in numerous metabolic disorders inclusive of diabetes mellitus and its complications. While micro RNA profile changes years before the occurrence of disease. This cross-sectional study was conducted in non-diabetic adults of diabetic and non-diabetic parents to explore the early changes in expression of micro RNA-29 family as it can be served as early biomarker of type 2 diabetes in non-diabetic adults. This study was conducted from January 2019 to January 2021. Micro RNA was extracted from plasma of 50 participants and expression was compared through qPCR. While data was analyzed through SPSS version 21.0. Results 29a and 29b had lower expression in participants with family history of DM compared to those having no family history of DM (P < 0.0001). While micro RNA 29c was found to be significantly higher in participants with positive family history of type 2 diabetes as compared to those without family history of diabetes (P = 0.001).
