Age-standardized Prevalence Of Diabetes Mellitus Research Articles

Prevalence of and factors associated with diabetes mellitus among people living with HIV in Vietnam.

Studies have shown that people living with HIV (PLWH) have a higher risk of having non-communicable diseases (NCDs) than do people without HIV. In Vietnam, HIV remains a major public health concern, and with recent rapid economic growth, NCDs such as diabetes mellitus (DM) have become a significant disease burden. This cross-sectional study was conducted to examine the prevalence of DM and the factors associated with DM among PLWH on antiretroviral therapy (ART). In total, 1,212 PLWH were included in the study. The age-standardized prevalence of DM and pre-diabetes were 9.29% and 10.32%, respectively. In the multivariate logistic regression analysis, male sex, age above 50 years, and body mass index ≥ 25 kg/m2 were associated with DM, and borderline p-value was found for associations with current smoking and years on ART. The results suggest higher DM prevalence among PLWH and that longer time on ART could be an important risk factor for DM among PLWH. These findings also suggest that interventions such as weight control and smoking cessation support could be provided at outpatient clinics. Integration of HIV/AIDS and NCDs services is essential to address health needs comprehensively and enhance health-related quality of life for PLWH.

Epidemiology of diabetes mellitus, pre-diabetes, undiagnosed and uncontrolled diabetes in Central Iran: results from Yazd health study

BackgroundOver the past few decades, the prevalence of Diabetes Mellitus (DM) has risen rapidly in Iran and other low and middle-income countries. We investigated the prevalence of DM, pre-diabetes, undiagnosed and uncontrolled diabetes and its relationship with some associated socioeconomic factors in the Yazd Greater Area in Iran.MethodsYazd Health Study is a longitudinal study conducted to determine the prevalence of non-communicable disease and related risk factors. In a two-step cluster sampling, 10,000 adults aged 20–69 years (200 clusters) were selected. In the recruitment phase, DM was considered if the patients had been either diagnosed DM by a physician or had fasting blood glucose ≥ 126 mg/dL. Chi square test was used for categorical variables to evaluate the differences and logistic regression model was applied to determine the predictors of diabetes.. P-value < 0.05 considered statistically significant.ResultsOf the 9965 individuals recruited, the crude self-reported prevalence of DM was 14.1% (95% CI: 13.4–14.7). The prevalence was higher in women than men (15.6 vs.12.4%), significantly. The age-standardized prevalence of DM was 8%. The prevalence was 14.9% in Yazd local people and 8.6% in those residents migrated from other provinces (P < 0.0001). We showed a significant association between DM prevalence and age, education, marital status, unemployment, insurance status, and positive family history (P < 0.0001). The prevalence of DM diagnosed by phycisians was 16.1% in participants (age-standardized prevalence: 8.3%). The subset analysis showed that 4.8% of patients were not aware of their disease. The prevalence of pre-diabetes was 25.8%. Of those with diabetes, 58.3% were not adequately controlled, which is not statistically significant with socio-economic status.ConclusionThe current study showed a high prevalence of DM in Yazd Greater Area which is closely related to some socio-demographic factors. The high prevalence of pre-diabetes is alarming. Effective strategies for DM prevention should be introduced. The majority of people with diabetes are aware, but half of them are not controlled. The ineffective care plan currently in use, should be reviewed. Patients needs to be encouraged to improve their lifestyle. Active follow-up of patients is recommended to ensure continuity of care.

Factors associated with medication adherence among people with diabetes mellitus in poor urban areas of Cambodia: A cross-sectional study.

BackgroundIn Cambodia, the age-standardized prevalence of diabetes mellitus has increased in both men and women. The main objective of this study was to identify factors associated with diabetes medication adherence among people with diabetes mellitus in poor urban areas of Phnom Penh, Cambodia.MethodsA cross-sectional study was conducted in 2017 using a structured questionnaire for face-to-face interviews by trained interviewers. The participants were people with diabetes mellitus who were the active members of a peer educator network, lived in poor urban areas of Phnom Penh, and attended weekly educational sessions during the survey period. Diabetes medication adherence was measured using four items of modified Morisky Medication Adherence Scale. Participants were classified into two groups based on their adherence score: 0 (high adherence) and from 1 to 4 (medium or low adherence). Sociodemographic characteristics; medical history; accessibility to health services; and knowledge, attitude, and practices related to diabetes mellitus were examined. A multiple logistic regression analysis was conducted adjusting for sex, age, marital status, and education levels.ResultsData from 773 people with diabetes were included in the analyses. Of the total, 49.3% had a high level of diabetes medication adherence. A high level of adherence was associated with higher family income (≥50 USD per month) (adjusted odds ratio [AOR] = 5.00, 95% confidence interval [CI] = 2.25–11.08), absence of diabetes mellitus-related complications (AOR = 1.66, 95% CI = 1.19–2.32), use of health services more than once per month (AOR = 2.87, 95% CI = 1.64–5.04), following special diet for diabetes mellitus (AOR = 1.81, 95% CI = 1.17–2.81), and absence of alcohol consumption (AOR = 13.67, 95% CI = 2.86–65.34).ConclusionsHigh diabetes medication adherence was associated with better family economic conditions, absence of diabetes mellitus-related complications, and healthy behaviors. It would be crucial to improve affordable access to regular follow-ups including promotion of healthy behaviors through health education and control of diabetes mellitus-related complications.

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.

The prevalence of and risk factors for diabetes mellitus and impaired glucose tolerance among Tibetans in China: a cross-sectional study.

The prevalence of diabetes mellitus (DM) and impaired glucose tolerance (IGT) has increased worldwide, although their prevalence and determinants among Tibetans are currently unknown. We thus aimed to explore the prevalence of and risk factors for DM and IGT among Tibetans in China. In 2011, 1659 Tibetan adults (aged ≥ 18 years) from Changdu, China, were recruited to this cross-sectional study. They completed a questionnaire and underwent physical examinations and laboratory testing to assess risk factors for DM and IGT. The age-standardized prevalence of DM and IGT among Tibetans was 6.2% and 19.7%, respectively. A higher annual family income, alcohol consumption, and higher fasting plasma glucose (FPG) level were risk factors for DM, with odds ratio (ORs) and 95% confidence intervals (CIs) of 3.48 (1.43–8.48; P = 0.006) for those with family incomes of > 1600 USD/year, 3.06 (1.31–7.17; P = 0.010) for alcohol consumption, and 13.99 (7.76–25.22; P < 0.001) for FPG level. However, altitude was found to be negatively associated with the risk of DM; compared to individuals living at < 3500 meters, the risk of DM decreased by 65% for those living at 3500–3999 meters (P = 0.034) and by 89% for those living at ≥ 4000 meters (P = 0.015). Age, FPG levels, and low-density lipoprotein cholesterol levels were significantly associated with IGT among Tibetans aged ≥ 18 years. These findings suggest that the prevalence of DM in Tibetans may continue to increase in future decades following rapid economic development, and it is crucial to address the management of conventional risk factors for reducing the disease burden of DM among Tibetans.

Prediabetes, diagnosed and undiagnosed diabetes, their risk factors and association with knowledge of diabetes in rural Bangladesh: The Bangladesh Population-based Diabetes and Eye Study.

The aim of the present study was to determine the prevalence and risk factors of prediabetes and diagnosed and undiagnosed diabetes mellitus (DM) in rural Bangladesh. Using a population-based cluster random sampling strategy, 3104 adults aged ≥30 years were recruited. Fasting capillary blood glucose, blood pressure, height, weight, waist circumference, and knowledge, attitudes, and practice related to diabetes were recorded. Diabetes was defined as fasting glucose (FG) ≥7.0 mmol/L or a self-reported diagnosis of diabetes; impaired FG (IFG) was defined as FG ≥ 6.1 and <7.0 mmol/L. The overall crude prevalence of DM was 7.2% (95% confidence interval [CI] 6.3%-8.1%; n = 222), of which 55% (n = 123) was previously undiagnosed (UDM). The prevalence of IFG was 5.3% (95% CI 4.5%-6.1%; n = 163). The age-standardized prevalence of DM and IFG was 6.6% and 5.0%, respectively. The prevalence of UDM was higher in people of lower socioeconomic status (59% vs. 31%; P < 0.001). Of those with known DM, 56% had poor glycemic control (FG ≥ 7.0 mmol/L) and 37% were not on medication. Overall knowledge of DM was poor; only 16.3%, 17.8%, and 13.4% of those with UDM, IFG, and normal FG knew that diabetes causes eye disease, compared with 55.6% of those with known DM (Ptrend < 0.001). In this rural Bangladeshi community, UDM was high. Lower socioeconomic status was associated with a higher risk of UDM. Overall knowledge of DM was poor. Public health programmes should target those of low socioeconomic status and aim to increase knowledge of DM in rural Bangladesh.

Increasing Prevalence of Type 2 Diabetes in a Rural Bangladeshi Population: A Population Based Study for 10 Years

BackgroundTo observe changes in the prevalence of type 2 diabetes mellitus (DM) and impaired fasting glucose (IFG) and its associated risk factors in a rural Bangladeshi population over a 10-year period.MethodsThree cross-sectional studies were undertaken in a rural community (aged ≥20 years) in 1999, 2004, and 2009. Structured questionnaires including sociodemographic parameters, anthropometric measurements, blood pressure, and blood glucose values were recorded. DM and IFG were diagnosed using 1999 World Health Organization criteria.ResultsAge standardized prevalence of DM increased significantly (P<0.001) from 1999 to 2009 (2.3%, 6.8%, and 7.9% in 1999, 2004, and 2009, respectively). The prevalence of IFG increased significantly (P=0.011) from 4.6% to 5.8% between 1999 and 2004 but then decreased from 5.8% to 5.3% during 2004 to 2009. Significant linear trends were shown in both sexes for general and central obesity as indicated by body mass index, waist circumference, and waist hip ratio (WHR). Increasing age and systolic blood pressure were significant risk factors for DM in all three studies. WHR for males was also significantly associated with the risk of DM in all three studies. WHR for females was only significantly associated with DM in 2009.ConclusionA significant rise in the prevalence of DM was observed in this population over 10 years. This increase was seen in both sexes, and in all age groups. A significant increase in the prevalence of the associated risk factors of general and central obesity was observed in both sexes.

Prevalence of Diabetes Mellitus, Glycemic Control, and Associated Factors in a Malay Population in Singapore

There is substantial heterogeneity regarding diabetes mellitus prevalence and glycemic control in Asian populations. The authors examined a population-based sample of 3000 adults (52% women) of Malay ethnicity (40-80 years) in Singapore. The age-standardized prevalence of diabetes mellitus was 18.4% (95% confidence interval = 17.0% to 19.8%). Being overweight, presence of hypertension, presence of cardiovascular disease, and family history of diabetes were found to be positively associated with diabetes mellitus. Higher education, employment status, and current smoking were found to be inversely associated with diabetes mellitus. Among those treated for diabetes, 29% achieved the optimal glycemic goal (glycosylated hemoglobin <7%). Lower levels of low-density lipoprotein cholesterol, total cholesterol, and systolic and diastolic blood pressure were associated with good glycemic control. Nearly 1 in 5 middle-aged Malay adults living in a developed Asian society had diabetes mellitus and a substantial proportion had suboptimal glycemic control.

Prevalence of diabetes and impaired glucose regulation in 45‐ to 64‐year‐old individuals in three areas of Finland

To determine the prevalence of diabetes mellitus (DM), impaired glucose tolerance (IGT) and impaired fasting glycaemia (IFG) and possible regional differences in Finnish adults aged between 45 and 64 years. A population sample of 2642 subjects aged between 45 and 64 years living in three geographical areas in Finland was invited to an oral glucose tolerance test. The glucose tolerance status of 2087 subjects (79.0%) was determined. The age-standardized prevalence of DM in men and women was 10.2% and 7.4%, respectively (P = 0.020 for difference between sexes), and that of IGT 10.5% in men and 9.2% in women. IFG in men was more than twice as common as in women (13.5% vs. 5.0%, respectively, P < 0.001). Abnormal glucose tolerance was most common in southern compared with southwestern and eastern Finland. Of all diabetic subjects, 44% were previously undiagnosed. The age-standardized prevalence of DM in 45- to 64-year-old Finns was within the range defined in previous studies on Europid populations. DM and IFG were more common in men than in women. Regional differences in the prevalence of abnormal glucose regulation suggest differences in lifestyle within an ethnically homogenous population.

The burden of diabetes mellitus in renal failure patients-a plea for MORE action NOW

A recent survey of 149 806 non-institutionalized adults aged 18 years or older in the United States (US) showed that the prevalence of diabetes mellitus (DM) rose from 4.9% in 1990 to 6.5% in 1998, with an increase of 33% (2). Increases were observed in both sexes, all ages, all ethnic groups, all education levels, and nearly all states in US. The prevalence of DM in Asian-Pacific region as well as Hong Kong is also in the increasing trend (3). The age-standardized prevalence of DM in Hong Kong was 7.7% in 1990 and 8.9% in 1995. The same rate in Taiwan was 11% in 1995 and 8.1% in Singapore in 1992 (3). It is these alarming figures making us worry about the future medical burden that the society will face with DM patients. In addition, the economic burden of DM in the society will increase. In 1997, the total medical expenditure in US incurred by diabetic patients was US$ 10 071 per capita, compared with US$ 2669 for the non-diabetic population (4).

Diabetes Mellitus among Navajo Indians: Findings from the Navajo Health and Nutrition Survey ,

Noninsulin-dependent diabetes mellitus is a major health problem among most American Indian tribes. This is the first population-based reservation-wide study of the Navajo that has used oral glucose tolerance testing to determine diabetes status. Employing WHO criteria, we found an age-standardized prevalence of diabetes mellitus (DM) of 22.9% among persons aged 20 y and older. This prevalence is 40% higher than any previous age-standardized estimate for the Navajo and four times higher than the age-standardized U.S. estimate. More than 40% of Navajo aged 45 y and older had DM. About one third of those with DM were unaware of it, with men more likely to be unaware than women. Among persons with a medical history of DM, almost 40% had fasting plasma glucose values ≥200 mg/dL. Persons with DM were heavier, more sedentary and more likely to have a family history of DM than were persons without DM. Persons with DM had more hypertension, lower HDL levels and higher triglyceride levels than their counterparts without DM. Insulin usage was infrequent among persons with a history of DM, and about one third of women with such a history used no medical therapy to control their diabetes. Although important measures to combat diabetes have already been undertaken by the Navajo, additional efforts are required to slow the progression of this disease and prevent its sequelae.
