Background: Up-to-date information on undiagnosed type 2 diabetes and prediabetes based on current diagnostic criteria is lacking. The study aimed to model the total numbers of people with undiagnosed type 2 diabetes and prediabetes in Denmark based on existing population-based surveys. Methods: Two population-based Danish studies with information on HbA1c, date of examination, gender, age and known type 2 diabetes were identified: the Danish General Suburban Population Study, n = 21,205, and the Danish Health Examination Survey, n = 18,065. The prevalence of known, undiagnosed and pre-diabetes were estimated in the Danish General Suburban Population Study, and population-level age-specific prevalence of known type 2 diabetes was estimated from national registers. The Danish Health Examination Survey was included for sensitivity analysis. Combining estimates of the survey participation rate among known type 2 diabetes patients with known overall participation rates from the studies allowed for the correction of survey prevalence to plausible population-level estimates of age- and gender-specific prevalence. Results: The prevalence of known, undiagnosed and pre-diabetes was highest among men, increasing with age with a peak at age 70. Applying the survey-based prevalence to the entire Danish population, the estimated number (May 2011) with undiagnosed type 2 diabetes was 60,681, corresponding to 24% of all type 2 diabetes cases, and 292,715 had prediabetes, about 50% more than the total type 2 diabetes population. Conclusions: Estimates of undiagnosed type 2 diabetes and prediabetes are dramatically lower than reported in previous studies (60,681 vs 200,000 and 292,715 vs 750,000); however, whether this reflects a true decrease in incidence or the change to HbA1c-based diagnostic criteria is not clear.

AbstractWe aimed to characterize the type 2 diabetes mellitus (T2DM) epidemic and the role of key risk factors in Jordan between 1990–2050, and to forecast the T2DM-related costs. A recently-developed population-level T2DM mathematical model was adapted and applied to Jordan. The model was fitted to six population-based survey data collected between 1990 and 2017. T2DM prevalence was 14.0% in 1990, and projected to be 16.0% in 2020, and 20.6% in 2050. The total predicted number of T2DM cases were 218,326 (12,313 were new cases) in 1990, 702,326 (36,941 were new cases) in 2020, and 1.9 million (79,419 were new cases) in 2050. Out of Jordan’s total health expenditure, 19.0% in 1990, 21.1% in 2020, and 25.2% in 2050 was forecasted to be spent on T2DM. The proportion of T2DM incident cases attributed to obesity was 55.6% in 1990, 59.5% in 2020, and 62.6% in 2050. Meanwhile, the combined contribution of smoking and physical inactivity hovered around 5% between 1990 and 2050. Jordan’s T2DM epidemic is predicted to grow sizably in the next three decades, driven by population ageing and high and increasing obesity levels. The national strategy to prevent T2DM needs to be strengthened by focusing it on preventive interventions targeting T2DM and key risk factors.

Abstract Background There is scarcity of representative population-based data on the health and wellbeing of asylum seekers in Europe. The Asylum Seekers Health and Wellbeing Survey (TERTTU) was launched to provide the evidence-base for developing services for asylum seekers as well as for planning and allocation of healthcare resources at a national level. Methods A sample of all first-time asylum applicants between 19.2-30.11.2018 was drawn from the Finnish Immigration Services electronic asylum database. Altogether 784 adults aged 18 years and older took part in the standardised health examination and face-to-face interview with participation rate of 79%. Interviewed health measures included the Minimum European Health Module, conditions previously diagnosed by a physician, permanent injury due to violence or accident and somatization. Results Self-rated health was good among 66% (95% CI 62,5-69,1) and 42% (95% CI 38,5-45,4) reported having some self-reported long-term illness or health problem. The most common previously diagnosed conditions were diseases of the circulatory system (19%, 95% CI 16,5-22,0), musculoskeletal system (18%, 95% CI 15,6-21,1), mental and behavioural disorders (13%, 95% CI 10,9-15,6) and diseases of the respiratory system (10%, 95% CI 8,0-12,2 ). Nearly half (47%, 95% CI 43,7-50,8) reported having a permanent injury due to violence or accident. Somatisation was common: 23% (95% CI 20,3-26,2) reported having headache, 23% (95% CI 19,9-25,8) back ache and 13% (95% CI 10,8-15,6) other pains at least several times a week. Conclusions The overall health of newly-arrived asylum seekers was poorer compared with the general Finnish population and migrant origin populations from similar countries of origin permanently living in Finland. Significant differences in asylum seekers health were found by sex and region of origin. Survey data will be used for developing the national initial health assessment protocol for asylum seekers during 2019. Key messages The TERTTU Survey is the largest population-based health examination survey among newly-arrived asylum seekers in Europe to date. The extensive data gathered over the course of the survey will be used for developing services for asylum seekers at a national level and is of high relevance also to other European countries.

IntroductionDiabetes mellitus is a growing public health epidemic in Asia. We examined the impact of type 2 diabetes, glycemic control and microvascular complications on mortality and cardiovascular outcomes in a multiethnic population-based cohort of Asians without prior cardiovascular disease.Research design and methodsThis was a prospective population-based cohort study in Singapore comprising participants from the three major Asian ethnic groups: Chinese, Malays and Indians, with baseline examination in 2004–2011. Participants with type 1 diabetes and those with cardiovascular disease at baseline were excluded. Type 2 diabetes, Hemoglobin A1c (HbA1c) levels and presence of microvascular complications (diabetic retinopathy and nephropathy) were defined at baseline. The primary outcome was all-cause mortality and major adverse cardiovascular events (MACEs), defined as a composite of cardiovascular mortality, myocardial infarction, stroke and revascularization, collected using a national registry.ResultsA total of 8541 subjects were included, of which 1890 had type 2 diabetes at baseline. Subjects were followed for a median of 6.4 (IQR 4.8–8.8) years. Diabetes was a significant predictor of mortality (adjusted HR 1.74, 95% CI 1.45 to 2.08, p<0.001) and MACE (adjusted HR 1.64, 95% CI 1.39 to 1.93, p<0.001). In those with diabetes, higher HbA1c levels were associated with increased MACE rates (adjusted HR (per 1% increase) 1.18, 95% CI 1.11 to 1.26, p<0.001) but not mortality (p=0.115). Subjects with two microvascular complications had significantly higher mortality and MACE compared with those with only either microvascular complication (adjusted p<0.05) and no microvascular complication (adjusted p<0.05).ConclusionDiabetes is a significant predictor of mortality and cardiovascular morbidity in Asian patients without prior cardiovascular disease. Among patients with type 2 diabetes, poorer glycemic control was associated with increased MACE but not mortality rates. Greater burden of microvascular complications identified a subset of patients with poorer outcomes.

AimsThe risks associated with diabetes, obesity and hypertension for severe COVID-19 may be confounded and differ by sociodemographic background. We assessed the risks associated with cardiometabolic factors for severe COVID-19 when accounting for socioeconomic factors and in subgroups by age, sex and region of birth.Methods and resultsIn this nationwide case–control study, 1.086 patients admitted to intensive care with COVID-19 requiring mechanical ventilation (cases), and 10.860 population-based controls matched for age, sex and district of residency were included from mandatory national registries. ORs with 95% CIs for associations between severe COVID-19 and exposures with adjustment for confounders were estimated using logistic regression. The median age was 62 years (IQR 52–70), and 3003 (24.9%) were women. Type 2 diabetes (OR, 2.3 (95% CI 1.9 to 2.7)), hypertension (OR, 1.7 (95% CI 1.5 to 2.0)), obesity (OR, 3.1 (95% CI 2.4 to 4.0)) and chronic kidney disease (OR, 2.5 (95% CI 1.7 to 3.7)) were all associated with severe COVID-19. In the younger subgroup (below 57 years), ORs were significantly higher for all cardiometabolic risk factors. The risk associated with type 2 diabetes was higher in women (p=0.001) and in patients with a region of birth outside European Union(EU) (p=0.004).ConclusionDiabetes, obesity and hypertension were all independently associated with severe COVID-19 with stronger associations in the younger population. Type 2 diabetes implied a greater risk among women and in non-EU immigrants. These findings, originating from high-quality Swedish registries, may be important to direct preventive measures such as vaccination to susceptible patient groups.Trial registration numberClinicaltrial.gov (NCT04426084).
