Abstract
OBJECTIVES To define pre-morbid, clinical, laboratory, and imaging features and identify prognostic factors associated with morbidity and mortality in patients with emphysematous pyelonephritis (EPN) and develop a prognostic scoring system for improving management outcomes. PATIENTS AND METHODS From January 2009 to December 2019, we performed a prospective study of all patients with a suspected diagnosis of EPN referred to a specialist tertiary centre in South India. All patients who underwent non-contrast computed tomography of the abdomen and those diagnosed with EPN were included in this study. Demographic parameters, imaging, haematological and microbiology results were recorded. Patients were divided into three groups: Group 1, patients who survived without any intervention; Group 2, those who survived with surgical intervention; and Group 3, those who died with or without intervention. A prognostic scoring system was developed from 18 different parameters and risk stratification was developed. The scores were correlated with overall prognosis. RESULTS Data from 131 patients with EPN enrolled in the study were analysed: Group 1 (n = 22), Group 2 (n = 102) and Group 3 (n = 7). By using univariate analysis, 10 factors were identified to be significantly associated with prognosis. Diabetes mellitus was the most common comorbidity. Shock at initial admission indicated a poor prognosis and warranted immediate attention (P < 0.001). CONCLUSIONS A multi-disciplinary approach, a high index of clinical suspicion, an early diagnosis and administration of culture-specific antibiotics with identification of prognostic indicators and risk stratification, allows prompt and appropriate medical and surgical treatments that could improve EPN management outcomes.

Abstract
AIM To conduct a systematic and critical review of published studies on prevalence of Type 2 diabetes mellitus (T2DM) in urban and rural areas of India. METHODS We conducted a literature search in PubMed, EMBASE and Web of Science using the terms 'prevalence', 'Type 2 diabetes, 'India', 'urban' and 'rural' for English language articles published during January 1994-December 2018. We selected articles that reported the results of original studies that randomly sampled adults aged 15-80 years, and which reported T2DM prevalence based on the actual examination of blood samples. RESULTS Of 1751 articles screened by titles and abstracts, 37 fulfilled our inclusion criteria. Majority (28 of 37; 76%) of studies were from South India, especially from the states of Tamil Nadu, Andhra Pradesh, Kerala and Karnataka. The prevalence of T2DM showed a wide range from 1.9% to 25.2%. Only 11 studies covering 24 regions separately reported the data by urban or rural location. Albeit inconsistent, 17 studies reported prevalence of T2DM by age group. CONCLUSION In this systematic review, we show that there remains an ambiguity about the actual prevalence of T2DM from India due to several factors. The findings underscore a strong need for having periodic regional surveillance involving appropriate epidemiological methods.

Abstract
Objective: The objective of the study is to analyze the risk factors determining the outcomes of patients with emphysematous pyelonephritis (EPN) by the adoption of a standardized management algorithm as well as to develop a prognostic scoring model to risk stratify these patients. Materials and Methods: The hospital records of 72 consecutive patients with EPN from February 2012 to January 2018 were retrospectively reviewed. Demographic, clinicoradiographic, and laboratory characteristics were recorded. Patients were managed with a standard management protocol and based on outcomes divided into three groups. Group I survived with conservative management, Group II survived after emergency nephrectomy, and Group III expired. The risk factors for nephrectomy and mortality were analyzed. Results: The mean age was 53 years. Male to female ratio was 4:5. There were 61 (84.7%), 4 (5.6%), and 7 (10%) patients in Groups I, II, and III, respectively. Diabetes mellitus was the most common comorbidity detected in 62 (86%) of patients. Type II EPN was the most common radiological presentation observed in 32 (44%) patients. Overall survival rate was 90%, and kidney salvage rate was 80%. Escherichia coli was the most common organism isolated. Thirty-two (45%) patients exhibited resistance to third-generation cephalosporin antibiotics. Thrombocytopenia, low body mass index (BMI), presence of >2 comorbidities, high total leukocyte count (TLC), and hypoalbuminemia were significantly associated with mortality. On adoption of the prognostic scoring system, mortality rates according to the risk subgroups were as follows: favorable - 0%, intermediate - 19%, and poor - 100%. Conclusion: Conservative management adopting appropriate algorithm reduces mortality and avoids unnecessary emergency nephrectomies. Thrombocytopenia, low BMI, presence of >2 comorbidities, high TLC, and hypoalbuminemia were significantly associated with mortality.

Abstract
OBJECTIVE Prevalence of type 2 diabetes varies by region and ancestry. However, most guidelines for the prevention of diabetes mellitus (DM) are based on European or non-Hispanic white populations. Two ethnic minority populations-Mexican Americans (MAs) in Texas, USA, and South Indians (SIs) in Tamil Nadu, India-have an increasing prevalence of DM. We aimed to understand the metabolic correlates of DM in these populations to improve risk stratification and DM prevention. RESEARCH DESIGN AND METHODS The Cameron County Hispanic Cohort (CCHC; n=3023) served as the MA sample, and the Population Study of Urban, Rural, and Semi-Urban Regions for the Detection of Endovascular Disease (PURSE; n=8080) served as the SI sample. Using design-based methods, we calculated the prevalence of DM and metabolic comorbidities in each cohort. We determined the association of DM with metabolic phenotypes to evaluate the relative contributions of obesity and metabolic health to the prevalence of DM. RESULTS In the CCHC (overall DM prevalence 26.2%), good metabolic health was associated with lower prevalence of DM, across age groups, regardless of obesity. In PURSE (overall prevalence 27.6%), probability of DM was not strongly associated with metabolic phenotypes, although DM prevalence was high in older age groups irrespective of metabolic health. CONCLUSION Our study provides robust, population-based data to estimate the prevalence of DM and its associations with metabolic health. Our results demonstrate differences in metabolic phenotypes in DM, which should inform DM prevention guidelines in non-European populations.

Abstract
INTRODUCTION Diabetes is a known risk factor for asymptomatic bacteriuria (ASB). However, the influence of diabetes on antenatal ASB was previously not addressed. AIM The prevalence of ASB, effect of risk factors and type of isolates and susceptibility patterns were studied in diabetic pregnancy. MATERIALS AND METHODS A total of 311 pregnant women were recruited for this study of which 103 were diabetic and 208 non-diabetic. A clean catch midstream urine samples were collected and cultured. The isolates were identified and antibiotic sensitivity was studied. The data was analysed by Chi-square test. RESULTS The prevalence of ASB in diabetic pregnancy was 38.83% (40/10(3); 95% CI: 23.73 - 53.94) and in non-diabetic pregnancy was 37.98% (79/208; CI: 27.28- 48.68). The odds ratio was not significant 1.0225 (95% CU: 0.65 - 1.599; p=0.922) and associated factors such as age and gestational period had no effect. The major isolates were Escherichia coli (25.0%), Staphylococcus aureus (22.5%), Coagulase negative staphylococci (CONS) (20.00%), and Klebsiella pneumonia (20.00%) in diabetic pregnancy and CONS (31.7%), E.coli (24.0%) and K.pneumonia (16.5%) in non-diabetic pregnancy. The isolates of diabetic pregnancy showed highest susceptibility to nitrofurantoin (56.4%), gentamicin (38.5%) and cotrimoxazole (38.5%) whereas that of non-diabetic pregnancy to gentamicin (43.0%), azithromycin (32.9%) and norfloxacin (30.4). There was no significant (p<0.05) difference in the type and susceptibly of the isolates between diabetic and non-diabetic pregnancy. CONCLUSION Diabetes has no significant influence on the prevalence of ASB in diabetic pregnancy both in terms of isolates and antibiotic susceptibility pattern.

Abstract
Type 2 diabetes (T2D) generally follows prediabetes (PD) conditions such as impaired fasting glucose (IFG) and/or impaired glucose tolerance (IGT). Although studies reported an association of IGT or IFG with cataract, the experimental basis for PD associated cataract is not known. Hence, we evaluated neonatal streptozotocin (nSTZ) induced rat model to study PD associated cataractogenesis by injecting STZ to two-day old rats. While majority (70%) of nSTZ injected pups developed IGT (nSTZ-PD) by two months but not cataract even after seven months, remaining (30%) nSTZ rats developed hyperglycemia (nSTZ-D) by two months and mature cataract by seven months. Lens biochemical analysis indicated increased oxidative stress as indicated by increased SOD activity, lipid peroxidation, and protein carbonyl levels in nSTZ-D cataractous lens. There was also increased polyol pathway as assessed by aldose reductase activity and sorbitol levels. Though nSTZ-PD animals have not shown any signs of lenticular opacity, insolubilization of proteins along with enhanced polyol pathway was observed in the lens. Further there was increased oxidative stress in lens of IGT animals. These results suggest that oxidative stress along with increased polyol pathway might play a role in IGT-associated lens abnormalities. In conclusion, nSTZ-PD rat model could aid to investigate IGT-associated lens abnormalities.

Abstract
BACKGROUND Diabetes mellitus is one of the diseases considered to be the main constituents of the global non-communicable disease (NCD) pandemic. Despite the large impact that NCDs are predicted to have, particularly in developing countries, estimates of disease burden are sparse and inconsistent. This systematic review transparently estimates prevalence of type 2 diabetes mellitus in Southern Asia, its association with urbanization and provides insight into the policy challenges facing the region. METHODS The databases Medline and PubMed were searched for population-based studies providing estimates of diabetes prevalence in the Southern Asia region. Studies using WHO diagnostic criteria of fasting plasma glucose (FPG) ≥7.0mmol/L and/or 2h-plasma glucose (2hPG) ≥11.1mmol/L were included. Data from eligible studies was extracted into bubble graphs, and trend lines were applied to UNPD figures to estimate age-specific prevalence in the regional population. Estimates specific to sex, area of residency, and diagnostic method were compared and trends analysed. RESULTS A total of 151 age-specific prevalence estimates were extracted from 39 studies. Diabetes prevalence was estimated to be 7.47% for 2005 and 7.60% for 2010. Prevalence was strongly associated with increased age, male gender and urban residency (P < 0.001). CONCLUSION Diabetes prevalence in Southern Asia is high and predicted to increase in the future as life expectancy rises and the region continues to urbanise. Countries in this region need to improve NCD surveillance and monitoring so policies can be informed with the best evidence. Programs for prevention need to be put in place, and health system capacity and access needs to be assessed and increased to deal with the predicted rise in NCD prevalence.

Abstract
Obesity is a worldwide pandemic, and the prevalence rate has doubled since the 1980s. Asian countries are also experiencing the global epidemic of obesity with its related health consequences. The prevalence of overweight and obesity are increasing at an alarming rate across all age groups in Asia. These increases are mainly attributed to rapid economic growth, which leads to socio-economic, nutrition and lifestyle transitions, resulting in a positive energy balance. In addition, fat mass and obesity-associated gene variants, copy number variants in chromosomes and epigenetic modifications have shown positive associations with the risk of obesity among Asians. In this review highlights of prevalence and related ecological and genetic factors that could influence the rapid rise in obesity among Asian populations are discussed.

Abstract
In 2011 census, 5.3% of the Indian population was > 65 years of age. This number has steadily grown over past few years and is steeply growing. Healthcare burden of elderly diabetics is immense and proper diagnosis and treatment alone can prevent further complications. According to the most recent surveillance data in U.S., the prevalence of diabetes among U.S. adults aged ≥65 years varies from 22 to 33%, depending on the diagnostic criteria used. In CSIR-NEERI, India, we have healthcare system wherein a fixed and limited number of patients are treated for their lifetime by qualified practitioners with negligible financial burden of the treatment costs. The patients have regular monthly follow up and hence we diagnose Diabetes and evaluate the control and diagnose micro vascular and macro vascular complications in all patients. We did retrospective analysis of all elderly patients following up in NEERI Hospital to find the exact prevalence of T2DM in elderly. It was observed that from total 585 elderly people, 178 had T2DM (30.42%- Prevalence). The sex ratio of Diabetic males to females was almost equal (1:0.97). Obesity was present in 114 people (64%). High prevalence of hypertension was found in Diabetic elderly population (80%). Comparing our prevalence rates with few other studies, it was found that our prevalence rates are quite high. The contributing factors may be urban living, with high prevalence of central obesity and Asian ethnicity, over and above, data of all patients undergoing treatment is available. We treated all diabetics with persistent values of Systolic BP > 130 mm of Hg and Diastolic values of BP > 80mm of Hg as Hypertensives, in order to achieve reduction in cardiovascular mortality and morbidity. This paper is for awareness of disease burden, in real primary care setup. It is not cross-sectional study but study with 100% inclusion of beneficiaries'. This is real world urban diabetes prevalence, also associated hypertension and central obesity prevalence.

Abstract
CONTEXT: The rise in diabetes mellitus (DM) portends a disaster of major proportion worldwide. AIM: To study the determinants of type-2 DM in people who are ≥45 years of age by selective screening methodology in rural area of Wardha district. SETTINGS AND DESIGN: A cross-sectional study in a rural area of Wardha district. METHODOLOGY: A cross-sectional population-based study was conducted among those who are at risk of developing DM, as per the WHO guidelines on Laboratory Diagnosis and monitoring of Diabetes Mellitus 2002. Blood glucose estimation was done using a blood glucose meter. STATISTICAL ANALYSIS USED: Multiple Logistic Regression. RESULTS: Eight point four nine percent of the 306 persons above the age of 45 years were diabetic. This study also revealed that the proportion of people diagnosed with DM increases with increasing age groups. Mean fasting and post meal blood glucose level (in mg%) among the study participants (nondiabetics) were 83.6 ± 1.6 and 129.9 ± 1.9 and mean fasting and post meal blood glucose level among diabetics were 138.8 ± 2.1 and 220.7 ± 1.9, respectively. The difference between the post meal blood glucose level among the diabetics and nondiabetics was statistically significant. The proportion of diabetics was more among those who had family history of diabetes (8.6%), BMI more than 25 (24.1%) and those with sedentary lifestyle (10.4%). CONCLUSIONS: Implementation of preventive measures to reduce the burden of diabetes is needed. Identification of the environmental factors adversely related to glucose intolerance helps evolve preventive strategies.

Abstract
AIMS To describe differences in prevalence of Type 2 diabetes mellitus with its associated risk factors between rural and urban populations in Bangladesh. Diagnostic criteria [fasting blood glucose (FBG) and oral glucose tolerance tests (OGTT)] were compared and reviewed for both populations. METHODS A total of 1555 subjects from urban and 4757 from rural communities (age > or = 20 years) with similar cultural and ethnic backgrounds were randomly selected in a cross-sectional survey. FBG values were determined from all and 2-h post-glucose capillary blood samples were determined after a 75-g oral glucose load for a selected number (urban 476, rural 1046). RESULTS A higher prevalence of diabetes was found in urban (8.1%) compared with rural populations (2.3%). Age, sex and waist-to-hip ratio for men were significant risk factors for both urban and rural subjects following fasting and 2-h post-glucose values adjusted for a number of confounding variables. Poor agreement was observed between FBG and OGTT for both urban (kappa 0.41) and rural (kappa 0.40) areas. CONCLUSIONS A higher prevalence of diabetes mellitus (DM) in the urban population was observed compared with rural subjects despite similar body mass indexes (BMI). Differences in obesity, waist/hip ratio or hypertension failed to explain the increasing occurrence of T2DM in the urban population.

Abstract
OBJECTIVE The aim of this study was to assess the association of intima-media thickness (IMT) and arterial stiffness with diabetic retinopathy in an Asian-Indian population that has very high prevalence rates of diabetes and coronary artery disease. RESEARCH DESIGN AND METHODS The study was conducted on 600 type 2 diabetic subjects randomly selected from the Chennai Urban Rural Epidemiology Study (CURES), which is an ongoing population-based study of a representative population of Chennai. When present, retinopathy was graded according to a modified Early Treatment Diabetic Retinopathy Study grading system. IMT was determined using high-resolution B-mode ultrasonography. Arterial stiffness was measured by assessing the augmentation index (AI) using the Sphygmocor apparatus. RESULTS Retinopathy was diagnosed in 116 of 590 (19.6%) subjects in whom retinal photography was possible. Mean values of IMT (0.93 +/- 0.36 vs. 0.85 +/- 0.21 mm, P = 0.001) and AI (27.9 +/- 8.9 vs. 25.8 +/- 9.6%, P = 0.031) were significantly higher among diabetic subjects with retinopathy compared with those without. Both IMT (P = 0.024) and AI (P = 0.050) showed a significant association to diabetic retinopathy, even after adjusting for age, duration of diabetes, HbA(1c), serum cholesterol, serum triglycerides, and microalbuminuria. CONCLUSIONS Diabetic retinopathy is associated with IMT and AI, suggesting that common pathogenic mechanisms might predispose to diabetic micro- and macroangiopathy.

Abstract
The diagnostic criteria for diabetes have been recently revised and the fasting plasma glucose (FPG) level reduced to 126 mg/dL, since the earlier cutoff of 140 mg/dL was considered to correspond to a much higher level than the 2-hour postglucose (2 h PG) value of 200 mg/dL. However, there are few data directly correlating FPG and 2 h PG during an oral glucose tolerance test (OGTT). This study reports on a retrospective analysis of 5,936 OGTTs performed at a diabetes center in South India and attempts to correlate the FPG and 2 h PG values. Using a 2 h PG of 200 mg/dL or higher as the diagnostic criterion, 46.7% of the cohort had diabetes. The corresponding values using the old FPG of 140 mg/dL or higher and the new FPG of 126 mg/dL or higher were 31.7% and 39.8%, respectively. If the FPG was further reduced to 118 mg/dL, the "diabetic yield" increased to 45.8%, ie, it approached the figures based on a 2 h PG of > or =200 mg/dL. Various regression equations were used to correlate FPG and 2 h PG values. When FPG was used as the dependent variable, the semilogarithmic regression equation provided the best fit, and using this model, the 2 h PG of 200 mg/dL corresponds to a FPG of 118 mg/dL. When the 2 h PG was used as the dependent variable, the log-log model provided the best fit, and using this model, a 2 h PG of 200 mg/dL corresponds to a FPG of 118 mg/dL. Thus, a FPG of 118 mg/dL seems to correlate with a 2 h PG of 200 mg/dL in South Indians.

Abstract
This cross-sectional population survey was undertaken to determine the prevalence of type 2 diabetes and impaired glucose tolerance in subjects aged 40 years or more in Kashmir Valley, India. The study was carried out in two phases. In phase one, 6091 randomly selected subjects, 40 years or older, from all six districts of the valley were surveyed for prevalence of known diabetes mellitus. In phase two, 5083 subjects, 40 years or older, were screened with oral glucose tolerance test for prevalence of undiagnosed (asymptomatic) diabetes mellitus and impaired glucose tolerance. Abnormalities of carbohydrate intolerance were determined as recommended by WHO. Of 6091 subjects interviewed, 115 were known cases of diabetes mellitus with an overall prevalence of 1.89% (1.98% in males and 1.77% in females). Results of glucose tolerance test revealed that mean fasting as well as mean 2 h blood glucose was significantly more in females as compared to males (4.68+/-0.91 and 6.40+/-2.12 vs. 4.49+/-0.96 and 5.94+/-2.03 mmol/l, respectively, P < 0.0001). Of 5083 subjects who were subjected to glucose tolerance test (GTT), 627 (12.34%) had an abnormal test; with 411 (8.09%) having impaired glucose tolerance (IGT) and 216 (4.25%) having diabetes mellitus. The prevalence of IGT as well as of diabetes was significantly more in females as compared to males (P < 0.001). Subjects who had family history of diabetes had a significantly higher prevalence of abnormal GTT. Prevalence of known diabetes as well as that of abnormal GTT steadily increased with age, with a highest prevalence in the age group of > or = 70 years (P < 0.001). Obese subjects had a significantly higher basal as well as 2 h blood glucose in males as well as in females. Subjects with diabetes on GTT had a higher waist/hip ratio. Overall the prevalence of diabetes as well as IGT was significantly higher in the urban population. We conclude that 1.89% of the general population have known diabetes, 4.25% have undiagnosed diabetes and 8.09% have impaired glucose tolerance test; making the total load of abnormal glucose tolerance 14.23% in Kashmir Valley. In subjects greater than 40 years of age having a family history of diabetes, obesity, higher age (50 years or above), female sex, and urban origin have more chance (odds ratio: 4.65, 2.30, 1.87, 1.49 and 1.16, respectively) of developing abnormal glucose tolerance.

Abstract
OBJECTIVE To determine the prevalence of diabetes and examine its association with food intake, anthropometric and metabolic variables, and other coronary risk factors in urban and rural older Mexican populations. DESIGN A cross-sectional study. SETTING Three Mexican communities (urban areas of medium and low income and a rural area). PARTICIPANTS A total of 121 men and 223 women aged 60 years and older and 93 men and 180 women aged 35 to 59 years were selected randomly for inclusion in the survey, which was derived from the CRONOS study (Cross-Cultural Research on Nutrition in the Older Adult Study Group) promoted by the European Economic Community. MEASUREMENTS A personal interview assessed demographic information, personal medical history, and functional status, and a 24-hour diet recall was obtained. A physical examination included anthropometric and blood pressure measurements. A fasting blood sample was obtained for measurements of lipids, insulin, and glucose. RESULTS Diabetes prevalence was higher in men than in women for all age groups: 16.7% versus 9.5% in younger adults and 30.8% versus 22.8% in older adults. For all age groups, diabetes was more highly prevalent in urban communities. Using a multivariate stepwise logistic regression, variables associated independently with diabetes in older individuals were: gender (male sex: OR = 2.1; P < .009); diminished carbohydrate intake in the diet (OR = 0.77; P < .03); central distribution of adiposity (OR = 1.9; P < .03); and functional disability (OR = 2.3; P < .01). This relationship was not observed with living area, income, education, fiber and alcohol intake, body mass index, or age. Individuals 80 years and older had a diminished atherogenic risk profile. Diabetes in older people was associated significantly with hypertriglyceridemia, impaired functional status, and an increased prevalence of ischemic heart disease; in younger adults diabetes was associated with low density lipoprotein (LDL) hypercholesterolemia, hypertriglyceridemia, and a proportionally higher fat intake. CONCLUSION This survey confirms the high prevalence of diabetes in the older Mexican population - particularly in men and in individuals living in urban areas - associated with an increased prevalence of other coronary risk factors. Diabetes was associated with higher fat, low carbohydrate, low fiber diets and increased prevalence of central distribution of adiposity. In the older subjects, diabetes was associated significantly with hypertriglyceridemia, impaired functional status, and increased prevalence of ischemic heart disease. A bias produced by early mortality and a survivorship effect must be considered in studies of older individuals. The health situation in the older Mexican population presents a complex problem that needs correct diagnosis and better strategies to benefit those segments of the population at increased risk.

Abstract
The objective of this study was to estimate the prevalence of diabetes among people aged 40 or more and to compare selected factors such as systolic and diastolic blood pressure, body mass index and lipid profile in diabetic and non-diabetic subjects. This is a cross-sectional study of subjects aged over 40 in Isfahan. Selection of diabetic subjects were based on multi-stage random sampling. Diabetes status was defined by the World Health Organization criteria and was based on fasting plasma glucose and oral glucose tolerance test results. Data on age, body mass index, blood pressure and lipid profile were obtained. Results show that a total of 3910 eligible subjects were examined and classified into different diabetes status. The overall age-standardized prevalence of diabetes was 7.54% (95% CI: 6.24-8.84%) in males and 7.97% (95% CI: 6.75-9.19%) in females with no difference. Similarly, the overall age standardized prevalence was 7.76% (95% CI: 6.87-8.65%). The prevalence of diabetes was shown to increased in the older age groups. Multiple logistic regression analysis showed that age, systolic blood pressure, hypertriglyceridemia, being overweight and also obesity were independently associated with diabetes. A large number of newly-diagnosed diabetic subjects were identified, which necessitates powerful screening programs. High levels of blood pressure, body mass index and lipid profile should draw attention to probable presence of diabetes.

Abstract
Epidemiological data from Asian Indians from Madras (AI) and Mexican Americans (MA) and non-Hispanic Whites (NHW) from San Antonio heart study were compared to determine the possible contributions by the anthropometric measurements to the varied prevalence of noninsulin dependent diabetes mellitus (NIDDM) in these ethnic groups. MA had the highest rate of obesity (mean body mass index (BMI) 28.9 +/- 5.9 kg/m2) and the highest prevalence of diabetes (men 19.6%; women 11.8%, P < 0.001 vs other groups). NHW although had high rates of obesity (mean BMI 26.2 +/- 5.2 kg/m2) had low prevalence of diabetes (men 4.4%; women 5.7%) than the AI (men 9.9%; women 5.7%) (Mean BMI 22.3 +/- 4.4 kg/m2, P < 0.001). Although AI had lower BMI than MA, the risk conferred by BMI was similarly high in AI and MA and both the ethnic groups had higher risks than NHW. Impaired glucose tolerance (IGT) was also more prevalent in MA than in AI (men, MA vs AI, 11.8 vs 7.5%, P < 0.003; women 16.1 vs 5.5%, P < 0.001). NHW had lower prevalence of IGT in men (5.7%) and women (6.3%) which were significantly lower (P < 0.001) compared to MA only. Age and BMI were predictive factors of NIDDM in all, while waist to hip ratio (WHR) was significant only in AI and MA, although NHW had high WHR. This may be an indicator of differences in genetic susceptibility. This study also highlights the similarity in risk factors between AI and MA living in urban environment and the significance of distribution of adiposity in the comparatively lean AI.

Abstract
OBJECTIVES To evaluate the prevalence of diabetes mellitus in older French subjects and to examine the different aspects of quality of life in an older diabetic population. DESIGN From a random sample of 2792 people older than age 65 living in the community, a diabetic sample was selected using three items from a questionnaire: Are you diabetic? Are you on a diabetic diet? What kind of medications do you take daily? Validation of the questionnaire was carried out previously to correct the observed prevalence. MEASUREMENTS The questionnaire assessed social and demographic aspects, physical, mental, and subjective health, and functional disabilities. Because quality of life assessment was mainly subjective, demented subjects were excluded. RESULTS The diabetic group consisted of 237 subjects from the older sample of 2792 (8.5%). No age difference was demonstrated between the two groups (mean, distribution), but the male/female ratio was significantly higher in those with diabetes (49.4% vs 39.3%, P = .003). Corrected prevalence of diabetes was 10.3%. After exclusion of demented subjects, 230/2726 people were investigated. Diabetic subjects were heavier (P < .001), had higher systolic blood pressure (P < .001), and had more frequent symptoms of ischemic heart disease (P < .001) and painful peripheral arterial disease (P < .001) and dyspnea (P < .001), but antecedents of stroke were similar in both groups. Diabetics were more often lacking in autonomy according to the IADL Lawton scale (P < .001), Rosow and Breslow scale (P < .001), and Mobility scale (P = .043), but not according to the Katz ADL scale. They more often exhibited symptoms of depression on the CES-D self-rating scale (21.3% vs 12.7%, P < .001), but evaluation of cognitive function was similar in both groups. Thirteen percent of diabetics, compared with 7.6% of non-diabetics, were unsatisfied with their own situation (P = .002). Health was rated as fair, bad, or very bad by 67.8% of diabetics compared with 49% of non-diabetics (P < .001). Diabetics rated themselves as feeling worse than others (15.3% vs 9.2%, P < < .001) and worried more about their health status (78% vs 63%, P < < .001). CONCLUSION The observed prevalence of diabetes in older French people living in the community was 8.5%. Quality of life in older diabetics was poorer than that of other people of the same age.

Abstract
To determine the prevalence of diabetes and hypertension, 6847 subjects of age 15 years or older, were investigated in a suburban population in Bangladesh. Fasting and post-prandial (capillary) blood glucose (2-hPG) was estimated. According to WHO criteria the crude prevalence of impaired glucose tolerance (IGT) was 7.5% and non-insulin-dependent diabetes mellitus (NIDDM) was 4.1%. The age standardized (30-64 years) prevalence of IGT was 7.7% with 95% confidence interval (CI) 6.96-8.44 and NIDDM was 4.5%, CI 3.94-5.12. Compared with the younger subjects the older subjects (< 40 vs. > or = 40 years) showed significant association with IGT (chi2, 65.9; P < 0.001) and NIDDM (chi2, 92.0; P < 0.001). Higher BMI (< or = 22.0 vs. > 22.1) was also significantly associated with IGT (chi2, 16.6; P < 0.001) and NIDDM (chi2, 83.9; P < 0.001). The higher BMI had stronger association with NIDDM than with IGT. Lower height showed significant association only with NIDDM. The logistic regression analyses also showed that increased age, higher BMI and short stature were independent risks for NIDDM. The study showed an increased prevalence of IGT and NIDDM among the suburban population of Bangladesh and the excess risk was observed with increased age, higher BMI and short stature.

Abstract
Several studies from the U.K. and the U.S. have shown that retinopathy was present at diagnosis of non-insulin dependent diabetes mellitus (NIDDM) indicating the likelihood of a latent phase of hyperglycaemia for a long period. This study looked for the prevalence of retinopathy at diagnosis of NIDDM in South Indian subjects who have a fairly high prevalence of diabetes and also a high rate of undetected diabetes. One thousand NIDDM subjects with varying duration of diabetes underwent detailed ophthalmoscopic examination for retinopathy. It was noted that the prevalence of retinopathy increased linearly with duration of diabetes. Among the 60 newly diagnosed NIDDM, 4 (6.7%) subjects had background diabetic retinopathy. Using a weighted linear regression analysis with percentage of retinopathy in relation to duration, it was estimated that hyperglycaemia could have been present 4.1 years prior to the diagnosis of NIDDM. Although the prevalence of retinopathy at diagnosis in South Indian NIDDM was lower than the other reported values, in view of the high prevalence of diabetes in Indians, a large number of patients would have the risk of microangiopathy even before diagnosis of diabetes is made.

Abstract
OBJECTIVE In view of the rapid increase in the prevalence of coronary artery disease (CAD) in developing countries, our aim was to determine the prevalence of CAD and its risk factors and lifestyle factors in an elderly population from north India. METHODS A random sample of 595 elderly subjects between 50 to 84 years of age was obtained from the urban population of Moradabad. The response rate was 90.1%. The survey methods included a questionnaire containing information on 7-day food intake, other lifestyle factors, Rose questionnaire for diagnosis of angina pectoris, a standard 12-lead electrocardiogram, blood pressure measurements and blood examination. RESULTS The total prevalence of CAD based on clinical history and electrocardiogram was 121/1000 (95% CI 72 to 165). The prevalence rate was slightly higher in males (130/1000) than in females (110/1000). The prevalence of CAD based on the Rose questionnaire was 57/1000 and based on electrocardiogram in 561 asymptomatic subjects was 67/1000. CAD was significantly higher in the elderly (65 to 84 years) group than in the middle-aged (50 to 64 years) group (168 vs. 97 per 1000), respectively. While the prevalence of hypertension was significantly higher in the elderly than middle-aged group respectively (214 vs. 168 per 1000), the prevalence of central obesity was significantly higher in the middle-aged than elderly group (674 vs. 632 per 1000). Other risk factors including smoking were comparable in the two subgroups. Prevalence of major risk factors and central obesity were significantly higher among patients with CAD than in the rest of the subjects. Prevalence of CAD was significantly higher in the middle and higher socio-economic groups compared to the lower income group. These higher income groups were also eating significantly higher amounts of visible fat and had a higher prevalence of physical inactivity (93.3%) compared to the lower income group. CONCLUSIONS CAD and its risk factors such as hypertension, hypercholesterolemia, diabetes and central obesity are of sufficient magnitude in the elderly population of India to be a major public health problem. The findings also indicate that CAD is more commonly associated with middle and higher socio-economic status which may be due to greater consumption of dietary fat and more sedentariness compared to lower socioeconomic groups.

Abstract
There are few data on the risk factors for diabetic nephropathy in the Asian Indian population, although several studies have shown a high prevalence of the disease in this ethnic group. This study also aimed to assess the role of hyperglycaemia and hypertension in the causation and course of nephropathy in this population, which has low rates of obesity. Retrospective analysis of two groups of non-insulin dependent diabetic (NIDDM) patients, one without proteinuria (< 100 mg/day, n = 25) and the other with proteinuria (> or = 500 mg/day, n = 25), matched for age, sex, duration of diabetes and body mass index (BMI) was done to study the factors predisposing to proteinuria and also its progression during a 2 year follow-up. Logistic regression analysis showed that the factors contributory to proteinuria were initial HbA1 and initial systolic blood pressure. The average proteinuria during the follow-up was dependent on the initial and average systolic and diastolic blood pressure values. No correlation was seen between cholesterol or triglyceride values and the change in proteinuria. Creatinine clearance deteriorated in the proteinuric group and this was related to the presence of proteinuria and initial diastolic blood pressure. This study emphasizes the importance of blood pressure in the progression of diabetic nephropathy, even in people who have low BMI. Therefore, good control of blood pressure has an important role to play in the management of this condition.
