Regional differences in the degree of glycaemic diabetes control in Spain and associated factors. IBERICAN study.

BACKGROUND AND OBJECTIVE: The prevalence of type 2 diabetes (T2D) is high, it is increasing and its degree of control seems to be improvable with important social and health consequences. The objective of this study is to determine the regional differences in the degree of glycaemic control of T2D in Spain and its associated factors. MATERIAL AND METHODS: Cross-sectional, multicentre, observational study in patients with T2D between 18 and 85 years of age selected by consecutive sampling between 2014 and 2018. The population was divided into four regions: north, centre, Mediterranean and south-east. The main variable was the value of glycated haemoglobin (HbA1c). Sociodemographic and clinical variables, presence or absence of other risk factors and treatment were recorded. RESULTS: A total of 1587 patients with T2D were analysed, with a mean age of 65.93 years (standard deviation [SD] 10.14); 54.5% were men; the mean duration of T2D was 8.63 years (SD 6.64) and the mean HbA1c value was 7.05%. Of the total, 59.8% had an HbA1c value ≤ 7% (north 59.5%, centre 59.5%, Mediterranean 60.6% and south-east 59.8%; P=.99). The factors for poor control were: in the north, duration of T2D and being sedentary; in the centre, duration of T2D and having a low income; in the Mediterranean, duration of T2D; and in the south-east, duration of T2D and having a low level of education or income. Overall, 76.2% of the subjects had hypertension, 75.1% dyslipidaemia, and 51.7% obesity, with significant differences between regions only being observed in the case of dyslipidaemia (P<.001). CONCLUSIONS: No differences were observed in the degree of diabetes control in the different regions, with the percentage of patients needing intensification in their control being high in all of them. The factors associated with poor control were the duration of the disease, a low level of education or income, and a sedentary lifestyle.

Clinical characteristics, treatment, and blood pressure control in patients with hypertension seen by primary care physicians in Spain: the IBERICAN study.

Objectives: To determine the clinical profile, according to the history of hypertension, the risk of developing hypertension, current antihypertensive treatment and BP control rates in patients with hypertension from the IBERICAN cohort. Methods: IBERICAN is an ongoing prospective cohort study, whose primary objective is to determine the frequency, incidence, and distribution of CVRF in the adult Spanish population seen in primary care settings. This analysis shows the baseline clinical characteristics of patients with hypertension. Adequate BP control was defined as BP <140/90 mmHg according to 2013 ESH/ESC guidelines. Results: A total of 8,066 patients were consecutively included, of whom 3,860 (48.0%) had hypertension. These patients were older (65.8 ± 10.9 vs. 51.6 ± 14.7 years; p < 0.001), had more cardiovascular risk factors, target organ damage and cardiovascular disease (CVD) in comparison with those without hypertension. The risk of hypertension increased with the presence of associated CV risk factors and comorbidities, particularly diabetes, obesity and the metabolic syndrome, and decreased with the intensity of physical activity. Regarding antihypertensive treatments, 6.1% of patients did not take any medication, 38.8% were taking one antihypertensive drug, 35.5% two drugs, and 19.6% three or more antihypertensive drugs. Overall, 58.3% achieved BP goals <140/90 mmHg. A greater probability of BP control was observed with increasing age of patients and the greater number of antihypertensive drugs. Blood pressure control was lower in hypertensive patients with diabetes, obesity, the metabolic syndrome, increased urinary albumin excretion, higher pulse pressure, and lack of antihypertensive treatment. Conclusions: About half of patients attended in primary care settings have hypertension in Spain. Patients with hypertension have a worse CV clinical profile than non-hypertensive patients, with greater association of CVRF and CVD. Around four out of ten patients do not achieve the recommended BP goals, and higher use of combination therapies is associated with a better BP control.

Prevalence of Hyperuricemia and Its Association with Cardiovascular Risk Factors and Subclinical Target Organ Damage.

The role of uric acid levels in the cardiovascular continuum is not clear. Our objective is to analyze the prevalence of hyperuricemia (HU) and its association with cardiovascular risk factors (CVRF), subclinical target organ damage (sTOD), and cardiovascular diseases (CVD). We evaluated the prevalence of HU in 6.927 patients included in the baseline visit of the IBERICAN study. HU was defined as uric acid levels above 6 mg/dL in women, and 7 mg/dL in men. Using adjusted logistic regression models, the odds ratios were estimated according to CVRF, sTOD, and CVD. The prevalence of HU was 16.3%. The risk of HU was higher in patients with pathological glomerular filtration rate (aOR: 2.92), heart failure (HF) (aOR: 1.91), abdominal obesity (aOR: 1.80), hypertension (HTN) (aOR: 1.65), use of thiazides (aOR: 1.54), left ventricular hypertrophy (LVH) (aOR: 1.36), atrial fibrillation (AFIB) (aOR: 1.29), and albuminuria (aOR: 1.27). On the other hand, being female (aOR: 0.82) showed a reduced risk. The prevalence of HU was higher in men, in patients presenting CVRF such as HTN and abdominal obesity, and with co-existence of LVH, atrial fibrillation (AFIB), HF, and any form of kidney injury. These associations raise the possibility that HU forms part of the early stages of the cardiovascular continuum. This may influence its management in Primary Healthcare because the presence of HU could mean an increased CV risk in the patients.

Prevalence of Chronic Heart Failure, Associated Factors, and Therapeutic Management in Primary Care Patients in Spain, IBERICAN Study.

BACKGROUND: The prevalence of chronic heart failure (CHF) in patients assisted in primary care is not well known. We investigated the prevalence of CHF, its associated factors, and its therapeutic management. METHODS AND FINDINGS: This was a cross-sectional, multicenter study conducted in primary care (PC) in baseline patients of the IBERICAN study (Identification of the Spanish Population at Cardiovascular and Renal Risk). CHF was defined as the presence of this condition in the medical history, classifying patients according to the type of ventricular dysfunction in CHF with preserved ejection fraction (pEF), or CHF with reduced ejection fraction (rEF). Clinical characteristics, relationship between CHF and main cardiovascular risk factors (CVRF), and drug treatments used according to ejection fraction (EF) were analyzed. RESULTS: A total of 8066 patients were included (54.5% women), average age (SD) was 57.9 (14.8) years, of which 3.1% (95% CI: 2.3-3.7) presented CHF, without differences between men and women. CHF with pEF (61.8%; 95% CI: 55.5-67.6) was more frequent in women, and CHF with rEF (38.1%; 95% CI: 33.2-45.5) (p = 0.028) was similar in both genders (65.9%; 95% CI: 57.1-73.4 vs. 57.3%; 95% CI: 47.7-65.8) (p = 0.188). A progressive increase of the prevalence with age (15.2% in ≥80 years) and with the aggregation of CVRF was observed. The most prescribed treatments were beta-blockers (54.7%) followed by angiotensin converting enzyme inhibitors (42.8%) and angiotensin II receptor antagonists (41.3%), without differences between pEF and rEF. The variables that are most associated with the probability of suffering CHF were a personal history of left ventricular hypertrophy (OR: 5.968; p < 0.001), of atrial fibrillation (OR: 3.494; p < 0.001), and of peripheral vascular disease (OR: 2.029; p < 0.001). CONCLUSIONS: Three in every 100 patients included in the IBERICAN study presented CHF, of which two thirds had pEF. The condition increased exponentially with age and aggregation of CVRF. We did not find any differences in drug treatment according to the type of ventricular dysfunction. The treatment of HF with rEF has much room for improvement.

Prevalence of Chronic Kidney Disease in Patients with Diabetes in Extremadura (Spain) during the Years 2012, 2013 and 2014: An Observational Study.

Diabetes mellitus (DM) is one of the leading causes of chronic kidney disease (CKD). We analyzed the prevalence of CKD in the population with diabetes in Extremadura (Spain). retrospective observational study was carried in the diabetic population attended in the Extremadura Health System in 2012-2014. A total of 38,253 patients, ≥18 years old were included. Estimated glomerular filtration rate (eGFR) was calculated using the CKD Epidemiology Collaboration equation. CKD was defined as follow: an eGFR <60 mL/min/1.73 m2 in a time period ≥ of three months or the presence of renal damage, with or without reduced eGFR, if the urine albumin-creatinine ratio (UACR) was ≥30 mg/g, also in a time period ≥ of three months. The prevalence rate of CKD was 25.3% (27.6% in women; 23.0% in men) and increases with age (34.0% in ≥65 years-olds). 24.9% of patients with CKD were in the very-high risk category for cardiovascular events (6.3% of the diabetic population). If CKD were diagnosed without requiring sustained eGFR <60 mL/min/1.73 m2 and/or sustained UACR ≥30 mg/g (as it is frequently found in the literature) this would overestimate the prevalence of CKD by 23%.

Prevalence of diabetes and frequency of glycated haemoglobin monitoring in Extremadura (Spain) during 2012, 2013 and 2014: An observational study.

AIMS: To analyze the prevalence of diabetes and the frequency of haemoglobin A1C (HbA1C) monitoring in the population with diabetes in Extremadura (Spain). METHODS: Observational, longitudinal retrospective study in the population attended in the Extremadura Health System in 2012-2014. A total of 403,644 glycated haemoglobin determinations in 189,466 subjects (52.4% female) were studied. All patients with a prescription of antidiabetic drugs and those who, despite not having treatment, had any determination of HbA1C ≥6.5% were considered as people with diabetes. All patients without treatment but with HbA1C ≥5.7% and <6.5% were considered prediabetes patients. RESULTS: The prevalence rate of diabetes was 8.3% and the frequency of HbA1C monitoring was 0.9/patient/year in the diabetic population. 48.2% of the patients with monitoring of HbA1C had diabetes, 21.2% had prediabetes, and 30.6% did not meet the criteria for diabetes or prediabetes. 12.7% of people with diabetes did not have determinations of HbA1C and only 11.8% have had ≥6 determinations in the period analyzed. CONCLUSIONS: The frequency of HbA1C monitoring in the diabetic population is lower than that usually recommended. Moreover, there is an inadequate use of HbA1C determinations, since one out of every 3 patients does not meet the criteria for diabetes or prediabetes.

Prevalence of depression in patients with type 2 diabetes attended in primary care in Spain.

OBJECTIVES: To estimate the prevalence of known and undiagnosed depression in patients with type 2 diabetes attended in primary care setting in Spain, and to determine the factors associated with the presence of depression. METHODS: This was a cross-sectional and multicenter study performed in a random sample of patients with type 2 diabetes attended in 21 primary care centers. Depressive symptoms were measured with the self-administered Patient Health Questionnaire (PHQ-9). RESULTS: A total of 411 patients were analyzed (mean age 70.8 (SD 10.3) years; 53.8% women). 29.2% of patients met the diagnostic criteria of depression, of whom 17% had known depression and 12.2% undiagnosed depression (PHQ-9 score ≥10, without a previous diagnosis of depression). Depression was more common in women (43.4%; 95% confidence interval [CI] 34.5-52.3%), widow (33.3%; 95% CI 27.9-38.7%), and hypothyroidism (12.5%; 95% CI 8.7-16.3%). Cardiovascular risk factors, the degree of control, complications related to diabetes, antidiabetic therapy and the number of drugs were not associated with the presence of depression. CONCLUSIONS: The prevalence of depression was high in patients with type 2 diabetes. However, in approximately 40% of patients depression was undiagnosed. The complications related to diabetes and antidiabetic therapy were not associated with the presence of depression.
