Trends In Prevalence Of Diabetes Research Articles

Trends of diabetes in Beijing, China.

The global rise in diabetes prevalence is a pressing concern. Despite initiatives like "The Healthy Beijing Action 2020-2030" advocating for increased awareness, treatment, and control, the specific situation in Beijing remains unexplored. This study aimed to analyze the trends in diabetes prevalence, awareness, treatment, and control among Beijing adults. Through a stratified multistage probability cluster sampling method, a series of representative cross-sectional surveys were conducted in Beijing from 2005 to 2022, targeting adults aged 18-79 years. A face-to-face questionnaire, along with body measurements and laboratory tests, were administered to 111,943 participants. Data from all survey were age- and/or gender-standardized based on the 2020 Beijing census population. Annual percentage rate change (APC) or average annual percentage rate change (AAPC) was calculated to determine prevalence trends over time. Complex sampling logistic regression models were employed to explore the relationship between various characteristics and diabetes. From 2005 to 2022, the total prevalence of diabetes among Beijing adults aged 18-79 years increased from 9.6% (95% CI: 8.8-10.4%) to 13.9% (95% CI: 13.1-14.7%), with an APC/AAPC of 2.1% (95% CI: 1.1-3.2%, P<0.05). Significant increases were observed among adults aged 18-39 years and rural residents. Undiagnosed diabetes rose from 3.5% (95% CI: 3.2-4.0%) to 7.2% (95% CI: 6.6-7.9%) with an APC/AAPC of 4.1% (95% CI: 0.5-7.3%, P<0.05). However, diabetes awareness and treatment rates showed annual declines of 1.4% (95% CI: -3.0% to -0.2%, P<0.05) and 1.3% (95% CI: -2.6% to -0.2%, P<0.05), respectively. The diabetes control rate decreased from 21.5% to 19.1%, although not statistically significant (APC/AAPC=-1.5%, 95% CI: -5.6% to 1.9%). Overweight and obesity were identified as risk factors for diabetes, with ORs of 1.65 (95% CI: 1.38-1.98) and 2.48 (95% CI: 2.07-2.99), respectively. The prevalence of diabetes in Beijing has significantly increased between 2005 and 2022, particularly among young adults and rural residents. Meanwhile, there has been a concerning decrease in diabetes awareness and treatment rates, while control rates have remained stagnant. Regular blood glucose testing, especially among adults aged 18-59 years, should be warranted. Furthermore, being male, elderly, overweight, or obese was associated with higher diabetes risk, suggesting the needs for targeted management strategies.

Trends in diabetes prevalence, awareness, treatment, and control in French-speaking Switzerland

Diabetes is increasing in Switzerland, but whether its management has improved is unknown. We aimed to assess diabetes prevalence, diagnosis, treatment, and control in French-speaking Switzerland. Our study used cross-sectional data for years 2005–2019 from a population-based study in Geneva, Switzerland. Overall prevalence (self-reported diagnosis and/or fasting plasma glucose level ≥ 7 mmol/L), diagnosed, treated (among diagnosed participants) and controlled diabetes (defined as a fasting plasma glucose FPG < 6.7 mmol/L among treated participants) were calculated for periods 2005–9, 2010–4 and 2015–9. Data from 12,348 participants (mean age ± standard deviation: 48.6 ± 13.5 years, 51.7% women) was used. Between 2005–9 and 2015–9, overall prevalence and frequency of diagnosed diabetes decreased (from 8.7 to 6.2% and from 7.0 to 5.2%, respectively). Among participants diagnosed with diabetes, treatment and control rates did not change from 44.1 to 51.9%, p = 0.251 and from 30.2 to 34.0%, p = 0.830, respectively. A trend towards higher treatment of participants with diabetes was found after multivariable adjustment, while no changes were found for overall prevalence, diagnosis, nor control. Among antidiabetic drugs, percentage of combinations increased from 12 to 23%; percentage of sulfonylureas and biguanides decreased from 15 to 6% and from 63 to 54%, respectively, while no trend was found for insulin. After multivariable analysis, women with diabetes were less likely to be treated but more likely to be controlled, the opposite association being found for obesity. In conclusion, in Canton Geneva, antidiabetic combination therapy is gaining importance, but only half of participants diagnosed with diabetes are treated, and glycaemic control remains poor.

Widening disparities in the national prevalence of diabetes mellitus for people with disabilities in South Korea

ObjectivesIn Korea, diabetes mellitus has a high disease burden, based on disability-adjusted life years. However, the disease burden is disproportionately distributed, with people with disabilities (PWD) experiencing higher rates of health disparities. Our study investigated long-term trends in diabetes prevalence and risk according to disability status, grade, and type. Study designRetrospective cohort study. MethodsApproximately 10 million individuals aged ≥30 years were included yearly from the National Health Information Database (NHID) and national disability registration data in Korea between 2008 and 2017, corresponding to 40 % of those aged ≥30 years in Korea. In 2017, 12, 975, 757 individuals were included; 5.5 % had disabilities. We estimated annual diabetes age-standardized prevalence and used multiple logistic regression analyses to estimate the odds of having diabetes in 2017, according to disability status, severity, and type. ResultsDiabetes age-standardized prevalence consistently increased over 2008–2017 in PWD and people without disabilities. However, the prevalence increased more rapidly and was higher in all years among PWD, with widening disparities based on disability status. Additionally, diabetes prevalence was high in all years for specific subgroups, including women, individuals with intellectual or mental disabilities or autism, and individuals with severe disabilities, suggesting further disparities among PWD. ConclusionsOur findings reveal health disparities between those with and without disabilities and among PWD subgroups. In addition to timely prevention, diabetes screening and management among PWD is vital. Public investment in improving disparities in the root causes of diabetes is essential, including health behaviours, healthcare utilization, and self-care.

Trends and risk factors of diabetes and prediabetes in US adolescents, 1999–2020

AimsTo assess the national trends in prevalence of diabetes and prediabetes and their major risk factors among adolescents in the US. MethodsWe analyzed data on 6,936 adolescents aged 12 to 19 years from the National Health and Nutrition Examination Surveys (NHANES) between 1999 and 2020. Diabetes was defined by self-reported physician-diagnosis (diagnosed) and by fasting plasma glucose and HbA1c levels (undiagnosed). Prediabetes was identified by fasting plasma glucose and HbA1c levels. Logistic regression was performed to estimate the associations of major risk factors with diabetes and prediabetes. ResultsThe prevalence of prediabetes in adolescents increased from 11.5% in 1999–2002 to 36.3% in 2015–2020. The prevalence of diabetes increased from 0.82% (0.62% of diagnosed and 0.20% of undiagnosed) in 1999–2002 to 1.14% (0.76% of diagnosed and 0.38% of undiagnosed) in 2015–2020, but the increase was not statistically significant (P value = 0.69). Obesity was significantly associated with higher odds of diabetes and prediabetes while boys and Mexican Americans had a significantly higher risk of prediabetes than their counterparts. ConclusionsThe prevalence of prediabetes among adolescents in the US has more than tripled from 1999 to 2020. Obese adolescents are at the greatest risk for diabetes and prediabetes.

The levels and trends of diabetes prevalence at national and sub-national levels in Iran (1990 - 2016).

The increasing trends in Diabetes prevalence and its attributed burden emphasized as an important issue that needs serious and urgent attention, all over the word. We estimated the mean Fasting Plasma Glucose (FPG) and the prevalence of Diabetes in aged 25years or older Iranian adults, by sex, age, province, and year through the time period of 1990 to 2016. In order to access the most comprehensive relevant data at the same time the systematic data searched added to the data of 5 national surveys and 7 sub-national population based investigations. Two round of modeling, including the Age-Spatio-Temporal and Gaussian Process Regression were used for estimation of mean FPG trend and uncertainties. To estimate Diabetes estimations in target groups, a crosswalk model was applies to the FPG estimates. The model reiterated separately for women and men. All of estimations standardized based on the Iran national census population of 2016 by year, age groups and sexes at national and sub-national levels. In 2016, the number of the diabetic population was 4.43 (3.93-4.99) million (2.38 million women). Between 1990 and 2016, the age-standardized mean of FPG increased from 84.69mg/dl (79.8-89.8) to 100.5mg/dl (97.9-103.3) in women and from 82.7mg/dl (78.3-87.5) to 98.8mg/dl (96.2-101.4) in men. Simultaneously, with considerable difference, the Diabetes prevalence, has increased from 6.1% (4.7-7.8) to 9.8% (8.7-11.1) in women and from 5.0% 18 (3.8-6.3) to 8.1% (7.2-9.2) in men (75% attributed to population growth). Considering the geographical patterns, the greatest increment in the prevalence of Diabetes detected in the northwestern and the central provinces. Significant increasing trends of Diabetes led to alarming threat, which can make the strategies and goals of our prevention programs out of control. We should plan for more effective communicative interventions for prevention and management of Diabetes, to be designed, implemented and monitored based on the updated scientific evidence.

The Trend in the Prevalence of Diabetes Mellitus in the Mexican Indigenous Population From 2000 to 2018

Diabetes is a worldwide public health problem. In Mexico, diabetes was the third leading cause of death in the total population in 2020. The indigenous people in Mexico are approximately 6%. This study aims to estimate the trends in diabetes prevalence from 2000 to 2018 in the group of Mexican indigenous language speakers and to analyze the main sociodemographic (e.g., age, educational and socioeconomic level, and the urbanicity of the area of residence) and clinical (e.g., age of diabetes onset, years with diabetes, and BMI) characteristics of this group. This cross-sectional study included participants aged ≥20 years from 4 National Health Surveys, 2000-2018. We presented the analyses for indigenous and nonindigenous strata. Logistic models adjusted were used to estimate the trend of diabetes in the study period. We found a significant increase in the prevalence of diabetes in the indigenous group. This trend in the ORs was maintained when adjusting for age, sex, waist circumference, and area of residence. For the study period, the prevalence change in diagnosed diabetes in the indigenous group was greater than that in the nonindigenous group (OR=6.4, 95% CI=4.1, 8.8 and OR=3.3, 95% CI=2.5, 4.1, respectively). We also found a significant prevalence change in undiagnosed diabetes for the indigenous group (OR=7.7, 95% CI=1.3, 14.6). In contrast to the results in nonindigenous populations, our main result reveals an increasing probability of being diabetic in the indigenous population from 2006 to 2018. It is necessary to clarify the origin of the accelerated change in diabetes prevalence among the indigenous population in Mexico.

Evolving Landscape of Diabetes Epidemic in Southeast Asia: Insights from National Family Health Survey.

Limited evidence on diabetes prevalence trends from the Indian subcontinent prompted this study to estimate the trends in diabetes prevalence using the National Family Health Survey (NFHS) data. A cross-sectional survey carried out between 2015-2016 (NFHS-4) and 2019-2021 (NFHS-5) in a nationally representative sample of adults (aged 20 to 54 years) was used. Diabetes was defined as the presence of: diagnosed diabetes (self-reported), fasting plasma glucose (FPG) ≥ 126 mg/dl, or a random plasma glucose (RPG) ≥200 mg/dl. "Fasting" was defined as the last food intake >8 hours and "random" as irrespective of the last meal. Diagnosed diabetes was defined as the presence of "self-reported diabetes" and undiagnosed diabetes was defined as FPG > 126 mg/dl or RPG ≥200 mg/dl. The crude prevalence of total diabetes increased from 3.5% (95% confidence interval (CI): 3.46-3.55) in 2015-2016 to 3.99% (95% CI: 3.94-4.04) in 2019-2021, a relative change of 14%. The increase was more in the poorest (1.77% vs 2.48%; P < 0.001) as compared to the rich (5.35%% vs· 5.43%; P = 0.847), rural areas (2.71% vs 3.38%; P < 0.001) as compared to urban (4.95% vs. 5.26%; P = 0.051), in normal weight individuals (1.87% vs. 2.16%; P < 0.001) as compared to obese (7.12% vs. 7.03%; P = 0.384). While the absolute prevalence of diabetes is highest amongst individuals residing in urban areas belonging to the rich wealth centile, the relative increase in the prevalence is disproportionately higher in those residing in rural areas, belonging to the poorest wealth centiles and having normal weight.

Latent growth trajectories of county-level diabetes prevalence in the United States, 2004–2017, and associations with overall environmental quality

Background:The prevalence of type 2 diabetes (T2D) has increased in the United States, and recent studies suggest that environmental factors contribute to T2D risk. We sought to understand if environmental factors were associated with the rate and magnitude of increase in diabetes prevalence at the county level.Methods:We obtained age-adjusted diabetes prevalence estimates from the CDC for 3,137 US counties from 2004 to 2017. We applied latent growth mixture models to these data to identify classes of counties with similar trends in diabetes prevalence over time, stratified by Rural Urban Continuum Codes (RUCC). We then compared mean values of the US EPA Environmental Quality Index (EQI) 2006–2010, overall and for each of the five domain indices (air, water, land, sociodemographic, and built), with RUCC-specific latent class to examine associations of environmental factors and class of diabetes prevalence trajectory.Results:Overall diabetes prevalence trends between 2004 and 2017 were similar across all RUCC strata. We identified two classes among metropolitan urbanized (RUCC 1) counties; four classes among non-metro urbanized (RUCC 2) counties; and three classes among less urbanized (RUCC 3) and thinly populated (RUCC 4) counties. Associations with overall EQI values and class of diabetes prevalence trends differed by RUCC strata, with the clearest association between poor air EQI and steeper increases in diabetes prevalence among rural counties (RUCC 3 and 4).Conclusions:Similarities in county-level diabetes prevalence trends between 2004 and 2017 were identified for each RUCC strata, although associations with environmental factors varied by rurality.

The Joint Secular Trends of Sleep Quality and Diabetes Among US Adults, 2005-2018.

Sleep quality has been related to the risk of diabetes; however, little is known about the prevalence of diabetes in the United States according to the levels of sleep quality. To examine the joint secular trends of the overall sleep quality and diabetes among US adults from 2005-2006 to 2017-2018. Seven cycles of cross-sectional National Health and Nutrition Examination Survey (NHANES) data between 2005-2006 and 2017-2018 were included. Nonpregnant adults aged 20 years or older were eligible for the study. A healthy sleep score was calculated to represent overall sleep quality. The prevalence of diabetes was estimated and mean levels of fasting plasma glucose (FPG), glycated hemoglobin, and insulin resistance were calculated. Both the estimated age-standardized prevalence of diabetes and changing trend in prevalence of diabetes varied by the overall sleep quality groups. The highest prevalence of diabetes was consistently observed in the low sleep quality group in each cycle, in which a significantly increasing trend was also noted across cycles (P for trend = .004). In contrast, the lowest prevalence of diabetes was consistently observed in the high sleep quality group in each cycle, in which no increasing trend over time was observed (P for trend = .346). Overall sleep quality decreased significantly between 2005-2006 and 2017-2018 among US adults. The estimated prevalence of diabetes and related measures only increased in participants with low or medium overall sleep quality but remained stable in participants with high sleep quality.

Abstract P166: The Joint Secular Trends Of Sleep Quality And Diabetes Among The US Adults

Introduction: Despite the extensive efforts in controlling diabetes-related modifiable risk factors, two recent studies showed that the estimated prevalence of diabetes in the U.S. has still increased in the past two decades. The sleep quality has been related to the risk of diabetes. Hypothesis: We examined the secular trends of the overall sleep quality, and the joint trends in the prevalence of diabetes by the overall sleep quality among US adults from 2005 to 2018. Methods: A total of 17,046 participants aged 20 years or older, from seven cycles of National Health and Nutrition Examination Survey (NHANES) data between 2005 to 2018, were eligible for the study. A healthy sleep score was calculated based on sleep 7-8 hours, no trouble sleeping, no snoring, no nocturia and no excessive daytime sleepiness to represent an overall sleep quality. The trends in estimated prevalence of diabetes were examined in different sleep quality groups. Results: From 2005 to 2018, the overall sleep quality significantly declined among US adults ( P for trend&lt;0.001). Both the estimated age-standardized prevalence of diabetes and changing trend in prevalence of diabetes varied by the overall sleep quality groups. The highest prevalence of diabetes was consistently observed in the low sleep quality group in each cycle, in which a significantly increasing trend was also noted across cycles ( P for trend=0.004). In contrast, the lowest prevalence of diabetes was consistently observed in the high sleep quality group in each cycle, in which no increasing trend over time was observed ( P for trend=0.346). Such differential secular trends by sleep quality were more significant among Non-Hispanic Whites than other racial/ethnic minorities. Conclusions: The overall sleep quality decreased significantly between 2005-2018 in U.S. adults. The estimated prevalence of diabetes only increased in participants with low or medium overall sleep quality but remained stable in participants with high sleep quality.

Trends in Prevalence of Diabetes and Control of Risk Factors in Diabetes Among US Adults, 1999-2018

Understanding population-wide trends in prevalence and control of diabetes is critical to planning public health approaches for prevention and management of the disease. To determine trends in prevalence of diabetes and control of risk factors in diabetes among US adults between 1999-2000 and 2017-2018. Ten cycles of cross-sectional National Health and Nutrition Examination Survey (NHANES) data between 1999-2000 and 2017-2018 were included. The study samples were weighted to be representative of the noninstitutionalized civilian resident US population. Adults aged 18 years or older were included, except pregnant women. Survey cycle. Diabetes was defined by self-report of diabetes diagnosis, fasting plasma glucose level of 126 mg/dL or more, or hemoglobin A1c (HbA1c) level of 6.5% or more. Three risk factor control goals were individualized HbA1c targets, blood pressure less than 130/80 mm Hg, and low-density lipoprotein cholesterol level less than 100 mg/dL. Prevalence of diabetes and proportion of adults with diagnosed diabetes who achieved risk factor control goals, overall and by sociodemographic variables, were estimated. Among the 28 143 participants included (weighted mean age, 48.2 years; 49.3% men), the estimated age-standardized prevalence of diabetes increased significantly from 9.8% (95% CI, 8.6%-11.1%) in 1999-2000 to 14.3% (95% CI, 12.9%-15.8%) in 2017-2018 (P for trend < .001). From 1999-2002 to 2015-2018, the estimated age-standardized proportion of adults with diagnosed diabetes who achieved blood pressure less than 130/80 mm Hg (P for trend = .007) and low-density lipoprotein cholesterol level less than 100 mg/dL (P for trend < .001) increased significantly, but not individualized HbA1c targets (P for trend = .51). In 2015-2018, 66.8% (95% CI, 63.2%-70.4%), 48.2% (95% CI, 44.6%-51.8%), and 59.7% (95% CI, 54.2%-65.2%) of adults with diagnosed diabetes achieved individualized HbA1c targets, blood pressure less than 130/80 mm Hg, and low-density lipoprotein cholesterol level less than 100 mg/dL, respectively. Only 21.2% of these adults (95% CI, 15.5%-26.8%) achieved all 3. During the entire study period, these 3 goals were significantly less likely to be achieved among young adults aged 18 to 44 years (vs older adults ≥65 years: estimated proportion, 7.4% vs 21.7%; adjusted odds ratio, 0.32 [95% CI, 0.16-0.63]), non-Hispanic Black adults (vs non-Hispanic White adults: estimated age-standardized proportion, 12.5% vs 20.6%; adjusted odds ratio, 0.60 [95% CI, 0.40-0.90]), and Mexican American adults (vs non-Hispanic White adults: estimated age-standardized proportion, 10.9% vs 20.6%; adjusted odds ratio, 0.48 [95% CI, 0.31-0.77]). Based on NHANES data from US adults, the estimated prevalence of diabetes increased significantly between 1999-2000 and 2017-2018. Only an estimated 21% of adults with diagnosed diabetes achieved all 3 risk factor control goals in 2015-2018.

Trends in Prevalence of Diabetes among Twin Pregnancies and Perinatal Outcomes in Catalonia between 2006 and 2015: The DIAGESTCAT Study.

The aims of our study were to evaluate the trends in the prevalence of diabetes among twin pregnancies in Catalonia, Spain between 2006 and 2015, to assess the influence of diabetes on perinatal outcomes of twin gestations and to ascertain the interaction between twin pregnancies and glycaemic status. A population-based study was conducted using the Spanish Minimum Basic Data Set. Cases of gestational diabetes mellitus (GDM) and pre-existing diabetes were identified using ICD-9-CM codes. Data from 743,762 singleton and 15,956 twin deliveries between 2006 and 2015 in Catalonia was analysed. Among twin pregnancies, 1088 (6.82%) were diagnosed with GDM and 83 (0.52%) had pre-existing diabetes. The prevalence of GDM among twin pregnancies increased from 6.01% in 2006 to 8.48% in 2015 (p < 0.001) and the prevalence of pre-existing diabetes remained stable (from 0.46% to 0.27%, p = 0.416). The risk of pre-eclampsia was higher in pre-existing diabetes (15.66%, p = 0.015) and GDM (11.39%, p < 0.001) than in normoglycaemic twin pregnancies (7.55%). Pre-existing diabetes increased the risk of prematurity (69.62% vs. 51.84%, p = 0.002) and large-for-gestational-age (LGA) infants (20.9% vs. 11.6%, p = 0.001) in twin gestations. An attenuating effect on several adverse perinatal outcomes was found between twin pregnancies and the presence of GDM and pre-existing diabetes. As a result, unlike in singleton pregnancies, diabetes did not increase the risk of all perinatal outcomes in twins and the effect of pre-existing diabetes on pre-eclampsia and LGA appeared to be attenuated. In conclusion, prevalence of GDM among twin pregnancies increased over the study period. Diabetes was associated with a higher risk of pre-eclampsia, prematurity and LGA in twin gestations. However, the impact of both, pre-existing diabetes and GDM, on twin pregnancy outcomes was attenuated when compared with its impact on singleton gestations.

Changes in the Diagnosis and Management of Diabetes in Mexico City Between 1998-2004 and 2015-2019.

OBJECTIVETo investigate the trends in diabetes prevalence, diagnosis, and management among Mexican adults who were participants in a long-term prospective study.RESEARCH DESIGN AND METHODSFrom 1998 to 2004, 159,755 adults from Mexico City were recruited to a prospective study, and from 2015 to 2019, 10,144 survivors were resurveyed. Diabetes was defined as self-reported diagnosis, glucose-lowering medication use, or HbA1c ≥6.5%. Controlled diabetes was defined as HbA1c <7%. Prevalence estimates were uniformly standardized for age, sex, and residential district. Cox models explored the relevance of controlled and inadequately controlled diabetes to cause-specific mortality.RESULTSDuring 1998–2004 and 2015–2019, 99,623 and 8,986 participants were aged 45–84 years. Diabetes prevalence had increased from 26% in 1998–2004 to 35% by 2015–2019. Of those with diabetes, the proportion previously diagnosed had increased from 76% to 89%, and glucose-lowering medication use among them had increased from 80% to 94%. Median HbA1c among those with diabetes had decreased from 8.2% to 7.3%, and the proportion of participants with controlled diabetes had increased from 16% to 37%. Use of blood pressure–lowering medication among those with previously diagnosed diabetes had increased from 35% to 51%, and their use of lipid-lowering therapy had increased from 1% to 14%. The excess mortality risk associated with diabetes accounted for 34% of deaths at ages 35–74 years, of which 5% were attributable to controlled and 29% to inadequately controlled diabetes.CONCLUSIONSInadequately controlled diabetes is a leading cause of premature adult death in Mexico. Improvements in diabetes management have increased diagnosis and control, but substantial opportunities remain to improve treatment, particularly with lipid-lowering therapy.

Changes in prevalence of diabetes over 15 years in a rural Australian population: The Crossroads Studies

AimsSecular trends in diabetes prevalence vary globally. We compared the prevalence of diabetes in two surveys 15 years apart in rural Australia. MethodTwo cross-sectional household surveys and clinics (biomedical assessments including oral glucose tolerance tests (OGTTs)) in 2001–2003 (Crossroads) and 2016–2018 (Crossroads-II).Setting: Four rural Victorian towns.Participants: Residents of randomly selected households (Crossroads (n = 5258), Crossroads-II (n = 2649)) with nested clinic assessments for randomly selected participants (n = 1048 and 736 respectively). Response rate 61%.Main outcome measures: Self-reported diagnosed diabetes, screening history, and diabetes defined by OGTT. ResultsThe age standardised prevalence of diagnosed diabetes increased from 5.0(4.4–5.7)% to 7.7(6.7–8.6)%, with crude prevalence increasing overall (5.4 to 10.4% p < 0.001), in the smaller towns (5.4 to 11.1% p = 0.001) and, the regional centre (4.1 to 7.3% p < 0.001). Screening for diabetes over the previous two years increased (rural towns 49.8 to 63.8%; regional centre 44.9 to 63.6%; both p < 0.001). The proportion of undiagnosed diabetes was 23.2% in 2003 and 13.7% in 2018. The age and sex adjusted change in total diabetes was (1.15(0.84–1.59)). Central obesity (adjusted odd ratio 1.28(1.00–1.64)) but not overall obesity (adjusted odd ratio 1.17(0.95–1.46)) increased over time. ConclusionsOver 15 years, the crude prevalence of diagnosed diabetes increased while the age and sex adjusted total diabetes prevalence did not change significantly. The epidemic may be slowing in some settings.

Abstract P363: Regional And Racial Variation In The Prevalence Of Concomitant Diabetes And Peripheral Artery Disease

Introduction and Objectives: Prior research has demonstrated regional and racial variation in the prevalence of concomitant diabetes and peripheral artery disease (PAD). However, trends in prevalence of diabetes and PAD across races has not been well explored in recent patient cohorts. Methods: Using data from the Centers for Medicare and Medicaid Services from 2003-2016, we identified patients concurrently diagnosed with both diabetes and PAD (n=10,506,254). Overall prevalence of concomitant diabetes and PAD was determined. Regional variation at the state and hospital referral region (HRR) level was then identified using zip code data. Racial demographics within Medicare data were used to stratify prevalence by race. Results: The overall prevalence of diabetes and PAD across the entire cohort was 15.3 per 1,000 Medicare patients. When stratified by HRR, prevalence of patients with concomitant diabetes and PAD varied by nearly 7-fold with a low of 5.0 and a high of 33.2 per 1,000 Medicare patients. When stratified by race, the number of new patients concomitantly diagnosed with diabetes and PAD decreased across all races, with the greatest decline seen in the Hispanic population (absolute decrease 1.84%, relative reduction 63%). The number of new black patients decreased as well (absolute decrease 1.40%, relative reduction 52%), but blacks continue to comprise the highest proportion of newly diagnosed patients at 1.29% (Figure 1). Conclusion: Significant regional and racial variation exists in the prevalence of concomitant diabetes and PAD diagnoses among Medicare patients with black patients remaining disproportionately affected. Efforts to improve prevention and care management should target these endemic regions and populations.

Potential impact of diabetes prevention on mortality and future burden of dementia and disability: a modelling study

Aims/hypothesisDiabetes is associated with an increased risk of dementia. We estimated the potential impact of trends in diabetes prevalence upon mortality and the future burden of dementia and disability in England and Wales.MethodsWe used a probabilistic multi-state, open cohort Markov model to integrate observed trends in diabetes, cardiovascular disease and dementia to forecast the occurrence of disability and dementia up to the year 2060. Model input data were taken from the English Longitudinal Study of Ageing, Office for National Statistics vital data and published effect estimates for health-state transition probabilities. The baseline scenario corresponded to recent trends in obesity: a 26% increase in the number of people with diabetes by 2060. This scenario was evaluated against three alternative projected trends in diabetes: increases of 49%, 20% and 7%.ResultsOur results suggest that changes in the trend in diabetes prevalence will lead to changes in mortality and incidence of dementia and disability, which will become visible after 10–15 years. If the relative prevalence of diabetes increases 49% by 2060, expected additional deaths would be approximately 255,000 (95% uncertainty interval [UI] 236,000–272,200), with 85,900 (71,500–101,600) cumulative additional cases of dementia and 104,900 (85,900–125,400) additional cases of disability. With a smaller relative increase in diabetes prevalence (7% increase by 2060), we estimated 222,200 (205,700–237,300) fewer deaths, and 77,000 (64,300–90,800) and 93,300 (76,700–111,400) fewer additional cases of dementia and disability, respectively, than the baseline case of a 26% increase in diabetes.Conclusions/interpretationReducing the burden of diabetes could result in substantial reductions in the incidence of dementia and disability over the medium to long term.

Trends in diabetes prevalence, awareness, treatment, control in Yangon, Myanmar between 2004-2014

Abstract Background In 2004, a survey in Yangon Region was conducted as the first STEP survey in Myanmar, which was repeated in 2014, assessing diabetes prevalence. Whether there have been any changes over time in the awareness, treatment and control status of diabetes is not known. The study aimed to assess changes in the prevalence, awareness, treatment and control of diabetes from 2004 to 2014, among adults in Yangon region. Methods The study was conducted in urban and rural areas of Yangon region, Myanmar, using two cross-sectional household based studies, in accordance with World Health Organization STEPS methodology. Men and women aged 25-74 years old participated in the studies (n = 4448 in 2004) and (n = 1372 in 2014). Logistic and linear regression were performed and outcome variables were diabetes and fasting plasma glucose. Results The overall age-standardized prevalence of diabetes were 8.3% (95% CI 6.5-10.6) in 2004 and 10.2% (7.6-13.6) in 2014 (p = 0.296). The diabetes prevalence increased from 2004 to 2014 only among participants aged ≥60 years, from 14.6% (11.7-18.1) to 31.9% (21.1-45.0) (p = 0.009). Awareness of having diabetes increased between 2004 and 2014 (44.3% (39.2, 49.6) to 69.4% (62.9-75.2)) (p &amp;lt; 0.001). Among participants who were aware of having diabetes, the proportion under treatment had increased between 2004 and 2014 from 55.1% (46.8-63.1) to 68.6% (61.5-74.8) (p = 0.015). There were no increase between 2004 and 2014 in the proportion of participants with controlled diabetes. After adjustments for age, sex and education, mean fasting plasma glucose levels in 2014 was 0.56 mmol/l (0.26-0.84) higher than in 2004. Conclusions The studies to monitor the development of diabetes prevalence in Myanmar are needed. Preventive measures to halt increases prevalence, to increase the detection rate of undiagnosed DM also treatment rate and to help people with diabetes to control their situation are needed. Key messages Mean plasma glucose levels were higher in 2014 than in 2004, but an increase in DM prevalence during this period was seen only among the oldest participants. The proportion of women being aware of having DM, as well as the proportion under treatment for most groups, had increased, however not the proportion under control.

Trends in Diabetes Prevalence, Awareness, Treatment and Control in Yangon Region, Myanmar, Between 2004 and 2014, Two Cross-Sectional Studies.

Myanmar is currently facing the burden of non-communicable diseases due to changes in lifestyle and dietary patterns linked to socio-economic development. However, evidence is scarce about changes in the prevalence of diabetes mellitus (DM) over time. We aimed to investigate changes in the prevalence, awareness, treatment and control of DM from 2004 to 2014, among adults aged 25–74 years, in the Yangon region. Two cross-sectional household-based studies, according to World Health Organization STEPwise approach to surveillance (WHO STEPS) methodology, were conducted in 2004 (n = 4448) and 2014 (n = 1372). The overall age-standardized prevalence of DM was 8.3% (95% CI 6.5–10.6) in 2004 and 10.2% (7.6–13.6) in 2014 (p = 0.296). The DM prevalence increased between the study years among elderly participants only, from 14.6% (11.7–18.1) to 31.9% (21.1–45.0) (p = 0.009). Awareness of having DM increased from 44.3% (39.2, 49.6) to 69.4% (62.9–75.2) (p < 0.001). Among participants who were aware of having DM, the proportion under treatment increased from 55.1% (46.8–63.1) to 68.6% (61.5–74.8) (p = 0.015). There was no change in proportion with controlled DM. Adjusted for age, sex and education, mean fasting plasma glucose levels in 2014 were 0.56 mmol/L (0.26–0.84) higher than in 2004. Preventive measures to halt future increases in DM prevalence and to increase the detection of undiagnosed DM cases are needed.

Prevalence and correlates of diabetes among criminal justice–involved individuals in the United States

PurposeDiabetes is one of the most prevalent and fastest-growing adverse health conditions in the United States and disproportionately affects those demographic and socioeconomic groups that are also more likely to be involved with the criminal justice (CJ) system. This study examines the prevalence and correlates of diabetes among CJ-involved individuals in the United States. MethodsUsing traditional statistical modeling and modern machine learning methods, data from the National Study on Drug Use and Health were analyzed to compare the correlates and predictive interactions of diabetes diagnosis among those respondents on probation and parole to a sample, matched by age and gender, who were not. ResultsSubjects involved in the CJ system were 15% more likely (1.66% vs. 1.44%, P = .015) to report a past-year diagnosis of diabetes than a sample of noninvolved individuals matched by age and sex, although this association was not statistically significant after adjusting for demographic and behavioral confounders. Similar trends in diabetes prevalence emerged for the non-CJ and CJ groups with regard to income, depression (OR of 2.38 and 1.65 for the CJ and non-CJ groups, respectively) and attainment of college education (OR of 0.64 and 0.30 for the CJ and non-CJ groups, respectively, compared with those with less than a high school education). Results also suggested that a generally high propensity toward risk taking had a negative effect on diabetes for the non-CJ group (OR 0.78; 95% CI 0.69–0.87), yet increased the odds of diabetes (OR 1.38; 95% CI 1.02–1.85) for the CJ group. ConclusionsInvolvement in the U.S. CJ system is correlated with a higher prevalence of diabetes and differing risk factors for diabetes diagnosis. Further research is necessary, however, to unpack the precise causal pathways that underlie the associational trends in the current analysis.
