Prevalence of diabetes mellitus in outpatients with essential hypertension in China: a cross-sectional study.

ABSTRACT:

Objectives

To investigate the prevalence of diabetes mellitus (DM) and new detection of DM using fasting plasma glucose (FPG) and 2 h plasma glucose (2-hPG) in hypertensive outpatients in China.

Design

Multicenter cross-sectional study.

Setting

46 hospitals in China.

Participants

Study patients were consecutively recruited from June to December 2009 from hypertension outpatient clinics in 46 hospitals in 22 provinces, autonomous regions and municipalities in China. At least 100 consecutive patients were recruited in each hospital. FPG was measured for all patients and 2-hPG was measured in those without a history of DM. A total of 4942 hypertensive outpatients aged ?20 years were included.

Results

Prevalence of DM was 24.3% (which included both previously and newly diagnosed cases). Among the 1202 patients with DM, 417 (34.7%) were newly detected. In patients aged <45 years, 52.6% of cases of DM were newly detected. Of the 417 cases of newly detected diabetes, 54.9% were identified using FPG tests and the remaining 45.1% by 2-hPG tests; 27.1% of patients with newly detected DM had FPG <6.1 mmol/L and 16.5% had FPG <5.6 mmol/L. Among the elderly patients (?65 years), 32.4% had normal FPG (<6.1 mmol/L) and 24.5% had optimal FPG (<5.6 mmol/L).

Conclusions

Our findings showed a high prevalence of DM and newly detected DM among Chinese hypertensive outpatients. Application of additional 2-hPG testing to FPG assay can improve the detection rate of DM, especially in elderly patients.

Project description:ObjectiveHypertension (HTN) is an important public health issue worldwide, associated with the rapid economic development and urbanisation over the last decades. This is especially the case in Shenzhen, which has benefited greatly from the reform and opening-up policies. However, there is limited information on the epidemiology of HTN in this region. This study was designed to investigate the prevalence, awareness, treatment and control of HTN and the associated factors among adult residents in Shenzhen, China.DesignPopulation-based, cross-sectional study.ParticipantsThrough the multistage stratified random sampling method, a representative sample of 10 043 urban population aged ≥18 years were selected. Three consecutive blood pressure (BP) readings were measured after resting for a 5 min seat by trained staff and HTN was defined as mean systolic BP ≥140 mm Hg and/or diastolic BP ≥90 mm Hg and/or self-reported current use of antihypertensive drugs. Participants were interviewed using a structured questionnaire. Anthropometric details, BP, blood and urine samples were also collected.Primary outcome measurePrevalence of HTN.ResultsOverall, the weighted prevalence of HTN among residents in Shenzhen was 19.2% (95% CI 18.5 to 20.0). Among patients with HTN, 55.0% (95% CI 52.9 to 57.1) were aware of their condition and 44.9% (95% CI 42.8 to 47.1) were taking antihypertensive medications, but only 21.7% (95% CI 20.0 to 23.5) achieved BP control. Among those who knew their HTN, 81.7% (95% CI 79.3 to 83.8) were under treatment and 48.3% (95% CI 45.1 to 51.5) were controlled among those with treated HTN. Male, older age, lower educational level, overweight and obesity, family history of HTN, tobacco smoking, alcohol intake, diabetes mellitus, dyslipidaemia and high uric acid were associated with HTN.ConclusionsHTN is a major public health concern in Shenzhen, which has low awareness, treatment and control rates, and is associated with several risk factors. Effective multifaceted implementation strategies are highly needed to combat the emerging burden of HTN.

Project description:BackgroundPrevious studies of inter-practice variation of the prevalence of hypertension and diabetes mellitus showed wide variations between practices. However, in these studies inter-practice variation was calculated without controlling for clustering of patients within practices and without adjusting for patient and practice characteristics. Therefore, in the present study inter-practice variation of diagnosed hypertension and diabetes mellitus prevalence rates was calculated by 1) using a multi-level design and 2) adjusting for patient and practice characteristics.MethodsData were used from the Netherlands Information Network of General Practice (LINH) in 2004. Of all 168.045 registered patients, the presence of hypertension, diabetes mellitus and all available ICPC coded symptoms and diseases related to hypertension and diabetes, were determined. Also, the characteristics of practices were used in the analyses. Multilevel logistic regression analyses were performed.ResultsThe 95% prevalence range for the practices for the prevalence of diagnosed hypertension and diabetes mellitus was 66.3 to 181.7 per 1000 patients and 22.2 to 65.8 per 1000 patients, respectively, after adjustment for patient and practice characteristics. The presence of hypertension and diabetes was best predicted by patient characteristics. The most important predictors of hypertension were obesity (OR = 3.5), presence of a lipid disorder (OR = 3.0), and diabetes mellitus (OR = 2.6), whereas the presence of diabetes mellitus was particularly predicted by retinopathy (OR = 8.5), lipid disorders (OR = 2.8) and hypertension (OR = 2.7).ConclusionAlthough not the optimal case-mix could be used in this study, we conclude that even after adjustment for patient (demographic variables and risk factors for hypertension and diabetes mellitus) and practice characteristics (practice size and presence of a practice nurse), there is a wide difference between general practices in the prevalence rates of diagnosed hypertension and diabetes mellitus.

Project description:BackgroundHypertension (HTN) is a common comorbidity among diabetic patients. Studies reported that HTN prevalence in patients with diabetes mellitus (DM) depends on many risk factors related to the disease (the type and duration of DM), patients (age, sex, race/ethnicity, BMI), and medical history (glycemic control, renal problems). Best to our knowledge, limited evidence is available in this regard among Jordanian population.ObjectivesThis retrospective cross-sectional study aimed to determine the prevalence of HTN among patients with DM in Jordan and factors that might be associated with the concurrence of both diseases.Materials and methodsA cross-sectional study was conducted to determine HTN prevalence and risk factors among diabetic outpatients in Jordan. Patients were asked about their sociodemographic information and medical history. A descriptive analysis was used to determine HTN prevalence and a fit bivariate logistic regression model was used to identify the significant risk factors of HTN in patients with type 2 DM (T2DM).ResultsHTN was found to be concurrently occurring in approximately 80% of T2DM patients. This was found to increase with age. In addition, dyslipidemia, gout disease, ischemic heart disease, renal impairment, or a family history of HTN were found to be associated with the concurrence of HTN among T2DM patients.ConclusionFindings from this study highlight the need for proper monitoring of DM patients to reduce the co-occurrence of HTN. Specific attention should be directed to control the patients' glycemic and lipid profiles as well as the cardiac and renal health using non-pharmacological and pharmacological measures. This is of particular importance in T2DM patients at old age and with family history of HTN, to reduce patients' deterioration. Results from this study will also be informative for the development of public health strategies to increase the awareness of the general population regarding T2DM and HTN since both diseases are very common among Jordanian population.
