Abstract Background The incidence rate of type 2 diabetes mellitus (T2DM) is rapidly increasing in Brazil, Russia, India, China, and South Africa (BRICS). The present study analyzed trends in T2DM incidence rate across the BRICS and associations with age, period, and birth cohort. Methods The incidence rate was estimated by the data obtained from GBD 2019 (Global Burden of Disease Study 2019) and was analyzed with the age-period-cohort framework. Incidence rates of T2DM (1990–2019) were collected for each 5-year age group (from 25 to 29 to 85–89 age group) stratified by gender from the Global Burden of Disease 2019 Study. Results In 2019, the the incidence rate of T2DM was 280.2 per 100,000 across the BRICS. Between 1990 and 2019, the incidence rate of T2DM among the BRICS population increased by 83.3%. In each period, as age increases, the incidence rate of T2DM in China and Russia first increased and then decreased, while the incidence rate of T2DM in Brazil, India and South Africa first increased and then decreased slightly with age group. Deteriorating period and cohort risks for incidence rate of T2DM were generally found across the BRICS. Conclusions The number of diabetic patients in the BRICS countries has continued to increase and the growth rate has been stable in the past 30 years, which is dependent on age and some other environmental factors. Some possible factors influencing T2DM incidence are analyzed and hypotheses generated through the age and period effects.

Abstract Background The United Nations acknowledged diabetes as an epidemic of the 21st century. Global trends demonstrate a continuing growth in its prevalence at approximately 2.5 % per year. The aim of the study was to analyse selected epidemiological factors for type 2 diabetes mellitus in Poland, Central Europe and the World. Methods This study presents Global Burden of Disease (GBD) data. Study describes the type 2 diabetes burden in the studied populations based on years lived with disability (YLD), years of life lost (YLL), and disability-adjusted life years (DALYs). Results Type 2 diabetes has been demonstrated to be a determinant of reduced life expectancy, as in the analysed period the condition presented an increasing trend, compared to other diseases. Conclusions In recent years the observed YLL, YLD and DALY values for type 2 diabetes have been comparable to the expected ones. Thus the prognosis presented by GBD may be used as a reliable source of information and a basis for a health policy that reduces the number of patients with diabetes and related complications, comorbidities or mortality.

Background The burden of diabetes is considerable not only globally but also nationally within Korea. The Global Burden of Disease study derived the disability-adjusted life years (DALYs) of diabetes depending on its complications as individual severity using prevalence-based approach from 2017. Conversely, the Korean National Burden of Disease study based on an incidence-based approach does not incorporate the severity of diseases. This study aimed to simulate incidence-based DALYs of type 2 diabetes mellitus (T2DM), given diabetic complications as disease severity using a Markov model. Methods We developed a model with six Markov states, including incident and existing prevalent cases of diabetes and its complications and death. We assumed that diabetes and its complications would not be cured. The cycle length was one year, and the endpoint of the simulation was 100 years. A 5% discount rate was adopted in the analysis. Transition cases were counted by 5-year age groups above 30 years of age. Age- and sex-specific transition probabilities were calculated based on the incident rate. Results The total DALY estimates of T2DM were 5,417 and 3,934 per 100,000 population in men and women, respectively. The years of life lost in men were relatively higher than those in women in most age groups except the 80–84 age group. The distribution of years lived with disability by gender and age group showed a bell shape, peaking in the 55–59 age group in men and 65–69 age group in women. Conclusions The burden of T2DM considering its complications was larger compared to the outcomes from previous studies, with more precise morbid duration using the Markov model.

Aims. Population-based incidence data are paramount to assess the effects of prevention strategies for diabetes, yet the relevant studies in mainland China are scarce. This study is aimed at estimating the type 2 diabetes mellitus (T2DM) incidence and time trends in Chinese adults. Material and Methods. Based on the Diabetes Surveillance System of Zhejiang Province, 879,769 newly diagnosed T2DM cases were identified from January 1, 2007, to December 31, 2017. Annual incidence, incidence rate ratios (IRRs), and average annual percentage change with their 95% confidence intervals (CIs) were reported. Results. The age-standardized overall incidence rate of T2DM was reported to be 281.73 (95% CI: 281.26-282.20) per 100,000 person-years, 293.19 (95% CI: 292.51-293.87) in males and 270.42 (95% CI: 269.76-271.09) in females. Compared with the ≥80 years age group, younger adults were at lower risk for T2DM (IRRs ranged from 0.035 to 0.986 and the 95% CIs did not include the null), except for the 70-79 years age group (IRR: 1.087, 95% CI: 1.077-1.097). Compared with females and rural areas, the risk for T2DM was higher in males (IRR: 1.083, 95% CI: 1.079-1.088) and urban areas (IRR: 1.005, 95% CI: 1.001-1.009), respectively. The standardized annual incidence rate increased from 164.85 in 2007 to 268.65 per 100,000 person-years in 2017, with an average annual increase of 4.01% and grew more rapidly in male, younger, and rural area populations. Conclusions. Our study suggested a significant increase in the incidence rate of T2DM among Chinese over the past decade, especially in adults characterized by male sex, younger age, and rural areas.

BackgroundEpidemiological trends of type 2 diabetes mellitus attributable to fine particulate matter (PM2.5) pollution remain unclear. Here, we estimated spatiotemporal trends of type 2 diabetes mellitus burden attributable to PM2.5 pollution, including ambient particulate matter pollution (APMP) and household air pollution (HAP), from 1990–2019.MethodsData were obtained from the Global Burden of Disease Study 2019 and were analyzed by age, sex, year, and location. Joinpoint regression analysis was applied in the analysis of temporal trends in type 2 diabetes mellitus burden over the 30 years.ResultsGlobally, PM2.5 pollution contributed to 292.5 thousand deaths and 13 million disability-adjusted life-years (DALYs) in 2019. APMP ranked third among all risk factors, causing an increase in type 2 diabetes mellitus burden from 1990, whereas the impact of HAP significantly fell during the same period. Both APMP and HAP contributed the most to deaths and DALYs of type 2 diabetes mellitus among older people. However, the age-standardized death and DALY rates of type 2 diabetes mellitus attributable to APMP were greater among males and people in the middle socio-demographic index countries, especially in Southern Sub-Saharan Africa. For HAP, type 2 diabetes mellitus burden was modestly higher in females and was highest in Oceania, which was the only region with an increase from 1990.ConclusionsPM2.5 pollution resulted in substantial and increasing type 2 diabetes mellitus burden worldwide. Hence, governments and health systems should take steps to reduce air pollution to mitigate this increasing burden.

Background: All these metabolic derangements exist for many years in the asymptomatic phase of type 2 diabetes and they predispose to development of complications even before clinical diagnosis. Metabolic syndrome is considered to be a precursor of type 2 diabetes. Present study is primarily aimed to study the prevalence of micro vascular complications and metabolic syndrome in newly diagnosed type 2 diabetes mellitus patients of low socio-economic group.Methods: This is a cross sectional prospective study conducted in the dept. of general medicine Konaseema institute of medical science Amalapuram, Andhra Pradesh, India from November 2016 to October 2018. Based on exclusion and inclusion criteria 103 patients were enrolled for this study. Various parameters like age, sex, body mass index, waist circumference, lipid profile, systolic and diastolic blood pressure, neuropathy, nephropathy and retinopathy was measured.Results: The mean age of the patient was 48±10.0 years. Fasting and 2 hours OGTT was 174.6±46.8 mg/dl and 255.6±75.6 mg/dl. The mean of total cholesterol was 204.7±41.9 (mg/dl), Triglycerides was 218±83.4 (mg/dl) and HDL was 44±5.3 (mg/dl). Symptomatic neuropathy constituted 35.6% in 51-60 age group and 27.1% in 31-40 and 41-50 age groups. Objective neuropathy constituted highest (36.6%) in 51-60 age group. Retinopathy constituted highest (60%) in 51-60 age group and nephropathy constituted 26.3 % in 21-30 and 51-60 age groups.Conclusions: Prevalence of microvascular complications in newly diagnosed diabetics of low socioeconomic group were as follows: symptomatic neuropathy-57.3%, objective neuropathy-39.8%, retinopathy-4.9%, nephropathy-18.4%. These were similar to published studies from general population from the same geographical area.

Background: Type 2 diabetes mellitus is a chronic, debilitating disease characterized by insulin resistance, impaired insulin secretion and hyperglycemia. It represents more than 90% of total prevalence of diabetes in the world and is responsible for 9% of the global mortality corresponding to four million deaths per year. The objective of the study was to assess the prevalence of diabetes mellitus type-2 in a rural population of age 30 years and above.Methods: A community based cross sectional study carried out in population 30 years and above in rural area of Khammam district in Telangana during the study period from 1st January to 31st December 2015. A total of 910 persons aged 30 years or more were included in study.Results: Near about 74 (8.1%) were diagnosed as type -2 diabetes mellitus. The prevalence of DM was 16.22% in 30-40 years age group, 24.32% in 41-50 years age group, 43.34% in 51-60 years age group and 16.2% in 61-70 years age group which shows that DM increases with age and the association between age and prevalence of type 2 DM was found to be statistically significant.Conclusions: There is a need to increase awareness of type–2 diabetes mellitus in the general population. Health education should be given in terms of risk factors of diabetes. They should be made aware about early screening methods.

Correction: The page numbers were changed from 98-100 to 81-93 on 31/08/2020. Background: Obesity is regarded as worldwide health problems which may put a person at a higher risk of serious health conditions leading to morbidity and mortality. Obesity is a risk factor for many diseases of which hypertension and type-2 diabetes mellitus are the most important. Hypertension, diabetes mellitus and obesity together form 24% of the global risk for mortality. Cardiovascular diseases related to these life-style disorders has major effect on life expectancy and impaired quality of life. Objectives: The study was done to evaluate the drug prescribing pattern of type - 2 diabetes and hypertension in both obese and non-obese patients. Along with it, this study also attempt to find the contributing factors associated with it and different types of drugs selected in those conditions respectively. Method: A descriptive cross-sectional study was conducted in 2074 at Manmohan memorial teaching hospital. A total of 101 out-patient were interviewed, measurements were done to calculate BMI and waist to hip ratio and their prescriptions were reviewed. For Treatment Guideline of HTN, JNC 8[20] was followed and Updated Treatment Guidelines for Type 2 Diabetes by the American Diabetes Association (ADA) [21] was followed in case of diabetes. Result: Among 101 patients studied, 58 were males and 43 were females. Regarding physical activity, only 26.7% of total patients were involved in morning walk and 3% in yoga, remaining 71% of study patients did not involve in any kind of physical exercise. Regarding food habits, 22.8% were smokers, 49.5% were alcoholics and 96% were non-vegetarians. Waist to hip ratio was also observed higher in both males (35.6%) and females (39.6%). Among the101 total participants, the age group of 41-55 years were found to be more obese than other age group (34 in numbers) followed by age group 56-70 which were 16 in numbers. Male patients were more obese (41) than female patients (31). Highest number (31) of the obese patients were diagnosed with type 2 diabetes mellitus, followed by second highest number (26) of patients diagnosed with hypertension and 15 patients with both the conditions. The commonly prescribed oral hypoglycemic drugs were metformin (35.60%) followed by glimepiride (24.80%). Among anti-hypertensive drugs, amlodipine (22.80%) was most common in prescriptions followed by losartan (18.80%) and Telmisartan (17.80%). Conclusion: The results of the present study show that higher number of male patients (41) were obese than female patients (31). About 30% of patients were found obese-diabetic, 26% were obese-hypertensive and 15% were with both obese diabetic and hypertensive condition. Among oral hypoglycemic drugs, metformin (35.60%) was mostly prescribed followed by glimepiride (24.80%). Among antihypertensives, amlodipine (22.8%) was mostly prescribed followed by losartan (18.80%). Atorvastatin (11.9%) was mostly prescribed oral hypolipidemic agent.
