Asociación de obesidad general y abdominal con hipertensión, dislipemia y presencia de prediabetes en el estudio PREDAPS / Association of general and abdominal obesity with hypertension, dyslipidemia and prediabetes in the PREDAPS study

Introducción y objetivos: Algunas medidas antropométricas muestran mayor capacidad que otras para discriminar la presencia de factores de riesgo cardiovascular. Este trabajo estima la magnitud de la asociación de diversos indicadores antropométricos de obesidad con hipertensión, dislipemia y prediabetes (glucemia basal o glucohemoglobina alteradas). Métodos: Análisis transversal de la información recogida en 2.022 sujetos del estudio PREDAPS (etapa basal). Se definió obesidad general como índice de masa corporal ≥ 30 kg/m2 y obesidad abdominal con 2 criterios: a) perímetro de cintura (PC) ≥ 102 cm en varones/PC ≥ 88 cm en mujeres, y b) índice cintura/estatura (ICE) ≥ 0,55. La magnitud de la asociación se estimó mediante regresión logística. Resultados: La hipertensión arterial mostró la asociación más alta con la obesidad general en mujeres (OR = 3,01; IC95%, 2,24-4,04) y con la obesidad abdominal según el criterio del ICE en varones (OR = 3,65; IC95%, 2,66-5,01). La hipertrigliceridemia y los valores bajos de colesterol unido a lipoproteínas de alta densidad mostraron la asociación más alta con obesidad abdominal según el criterio del ICE en mujeres (OR = 2,49; IC95%, 1,68-3,67 y OR = 2,70; IC95%, 1,89-3,86) y la obesidad general en varones (OR = 2,06; IC95%, 1,56-2,73 y OR = 1,68; IC95%, 1,21-2,33). La prediabetes mostró la asociación más alta con obesidad abdominal según el criterio del ICE en mujeres (OR = 2,48; IC95%, 1,85-3,33) y con obesidad abdominal según el criterio del PC en varones (OR = 2,33; IC95%, 1,75-3,08). Conclusiones: Los indicadores de obesidad abdominal mostraron la mayor asociación con la presencia de prediabetes. La relación de los indicadores antropométricos con hipertensión y con dislipemia mostró resultados heterogéneos (AU)

Introduction and objectives: Some anthropometric measurements show a greater capacity than others to identify the presence of cardiovascular risk factors. This study estimated the magnitude of the association of different anthropometric indicators of obesity with hypertension, dyslipidemia, and prediabetes (altered fasting plasma glucose and/or glycosylated hemoglobin). Methods: Cross-sectional analysis of information collected from 2022 participants in the PREDAPS study (baseline phase). General obesity was defined as body mass index ≥ 30 kg/m2 and abdominal obesity was defined with 2 criteria: a) waist circumference (WC) ≥ 102 cm in men/WC ≥ 88 cm in women, and b) waist-height ratio (WHtR) ≥ 0.55. The magnitude of the association was estimated by logistic regression. Results: Hypertension showed the strongest association with general obesity in women (OR, 3.01; 95%CI, 2.24-4.04) and with abdominal obesity based on the WHtR criterion in men (OR, 3.65; 95%CI, 2.66-5.01). Hypertriglyceridemia and low levels of high-density lipoprotein cholesterol showed the strongest association with abdominal obesity based on the WHtR criterion in women (OR, 2.49; 95%CI, 1.68-3.67 and OR, 2.70; 95%CI, 1.89-3.86) and with general obesity in men (OR, 2.06; 95%CI, 1.56-2.73 and OR, 1.68; 95%CI, 1.21-2.33). Prediabetes showed the strongest association with abdominal obesity based on the WHtR criterion in women (OR, 2.48; 95%CI, 1.85-3.33) and with abdominal obesity based on the WC criterion in men (OR, 2.33; 95%CI, 1.75-3.08). Conclusions: Abdominal obesity indicators showed the strongest association with the presence of prediabetes. The association of anthropometric indicators with hypertension and dyslipidemia showed heterogeneous results (AU)

The impact of a programme to improve quality of care for people with type 2 diabetes on hard to reach groups: The GEDAPS study.

AIMS: We investigated whether a continuous quality improvement programme in primary care for people with type 2 diabetes led to better care and outcomes in hard to reach groups. METHODS: GEDAPS was implemented in Catalonia, Spain between 1993 (n=2239) and 2002 (n=5819). Process (e.g., education), intermediate (e.g., HbA1c) and final (e.g. retinopathy) outcomes were compared between urban and rural areas, and between younger (≤74 years) and older (≥75 years) individuals as examples of harder to reach groups. RESULTS: In 1993, people in urban areas had significantly better or similar outcomes to rural areas; by 2002, most outcomes improved in urban and rural areas. For all outcomes, the improvement in rural areas was similar to or better than urban areas. Similarly, for most outcomes, the younger and older group improved, with the older group experiencing similar or better improvements than the younger group for all indicators, except coronary artery disease. CONCLUSIONS: A quality improvement programme was associated with equivalent or better outcomes in hard to reach groups, regardless of whether they were specifically targeted. The ability to apply one programme to all populations could save time and money.

Continued smoking abstinence in diabetic patients in primary care: a cluster randomized controlled multicenter study.

AIMS: To assess the effectiveness of an intensive smoking cessation intervention based on the transtheoretical model of change (TTM) in diabetic smokers attending primary care. METHODS: A cluster randomized controlled clinical trial was designed in which the unit of randomization (intervention vs. usual care) was the primary care team. An intensive, individualized intervention using motivational interview and therapies and medications adapted to the patient's stage of change was delivered. The duration of the study was 1 year. RESULTS: A total of 722 people with diabetes who were smokers (345 in the intervention group and 377 in the control group) completed the study. After 1 year, continued abstinence was recorded in 90 (26.1%) patients in the intervention group and in 67 (17.8%) controls (p=0.007). In patients with smoking abstinence, there was a higher percentage in the precontemplation and contemplation stages at baseline in the intervention group than in controls (21.2% vs. 13.7%, p=0.024). When the precontemplation stage was taken as reference (OR=1.0), preparation/action stage at baseline showed a protective effect, decreasing 3.41 times odds of continuing smoking (OR=0.293 95% CI 0.179-0.479, p<0.001). Contemplation stage at baseline also showed a protective effect, decreasing the odds of continuing smoking (OR=0.518, 95% CI 0.318-0.845, p=0.008). CONCLUSIONS: An intensive intervention adapted to the individual stage of change delivered in primary care was feasible and effective, with a smoking cessation rate of 26.1% after 1 year.

Chronic kidney disease in the type 2 diabetic patients: prevalence and associated variables in a random sample of 2642 patients of a Mediterranean area.

BACKGROUND: Kidney disease is associated with an increased total mortality and cardiovascular morbimortality in the general population and in patients with Type 2 diabetes. The aim of this study is to determine the prevalence of kidney disease and different types of renal disease in patients with type 2 diabetes (T2DM). METHODS: Cross-sectional study in a random sample of 2,642 T2DM patients cared for in primary care during 2007. Studied variables: demographic and clinical characteristics, pharmacological treatments and T2DM complications (diabetic foot, retinopathy, coronary heart disease and stroke). Variables of renal function were defined as follows: 1) Microalbuminuria: albumin excretion rate & 30 mg/g or 3.5 mg/mmol, 2) Macroalbuminuria: albumin excretion rate & 300 mg/g or 35 mg/mmol, 3) Kidney disease (KD): glomerular filtration rate according to Modification of Diet in Renal Disease < 60 ml/min/1.73 m2 and/or the presence of albuminuria, 4) Renal impairment (RI): glomerular filtration rate < 60 ml/min/1.73 m2, 5) Nonalbuminuric RI: glomerular filtration rate < 60 ml/min/1.73 m2 without albuminuria and, 5) Diabetic nephropathy (DN): macroalbuminuria or microalbuminuria plus diabetic retinopathy. RESULTS: The prevalence of different types of renal disease in patients was: 34.1% KD, 22.9% RI, 19.5% albuminuria and 16.4% diabetic nephropathy (DN). The prevalence of albuminuria without RI (13.5%) and nonalbuminuric RI (14.7%) was similar. After adjusting per age, BMI, cholesterol, blood pressure and macrovascular disease, RI was significantly associated with the female gender (OR 2.20; CI 95% 1.86-2.59), microvascular disease (OR 2.14; CI 95% 1.8-2.54) and insulin treatment (OR 1.82; CI 95% 1.39-2.38), and inversely associated with HbA1c (OR 0.85 for every 1% increase; CI 95% 0.80-0.91). Albuminuria without RI was inversely associated with the female gender (OR 0.27; CI 95% 0.21-0.35), duration of diabetes (OR 0.94 per year; CI 95% 0.91-0.97) and directly associated with HbA1c (OR 1.19 for every 1% increase; CI 95% 1.09-1.3). CONCLUSIONS: One-third of the sample population in this study has KD. The presence or absence of albuminuria identifies two subgroups with different characteristics related to gender, the duration of diabetes and metabolic status of the patient. It is important to determine both albuminuria and GFR estimation to diagnose KD.

Trends in chronic complications of type 2 diabetic patients from Spanish primary health care centres (GEDAPS study): ten year-implementation of St. Vincent recommendations.

AIMS: To assess the implementation of St. Vincent recommendations in Catalonia (Spain) between 1993 and 2003 following a program of Continuous Quality Improvement. METHODS: 65 health centres (433 health professionals) took part in the study. From 1993 to 2003, 34 workshops on consensus guidelines and feedback referring to the variables that needed to be improved were carried out. Data collection was obtained concerning, socio-demographic information, and disease characteristics and complications from patients with type 2 diabetes mellitus (DM). RESULTS: Most cardiovascular risk factors improved: glycosilated haemoglobin (HbA1c) was reduced by 0.7% (95% CI: -0.49:-0.90); total cholesterol by 0.54mmol/L (95% CI: -0.53:-0.55); non-high density lipoprotein cholesterol by 0.81mmol/L (95% CI: -0.80:-0.82); systolic blood pressure (SBP) by 6.02mmHg (95% CI: -5.79:-6.25), and diastolic blood pressure (DBP) by 2.65mmHg (95% CI: -2.4:-2.9), with the exception of smoking and obesity, which increased by 2.1% and 5.9%, respectively. Retinopathy and albuminuria decreased by 40.7% and 46% (p<0.001), respectively. The incidence of diabetic foot lesions and amputations decreased by 65.7% and 61.1% (p<0.001), respectively. The prevalence of macrovascular complications showed a slight reduction (p=0.037). Ischemic cardiomyopathy and cerebrovascular accidents decreased by 7.7% and 17.6%, respectively. CONCLUSIONS: Our Continuous Quality Improvement program based on St. Vincent recommendations, had a positive impact on cardiovascular risk factors. We observed a reduction of chronic complications in type 2 DM patients.

Multifactorial control and treatment intensity of type-2 diabetes in primary care settings in Catalonia.

BACKGROUND: Many studies on diabetes have demonstrated that an intensive control of glycaemia and the main associated risk factors (hypertension, dislipidaemia, obesity and smoking) reduce cardiovascular morbi-mortality. Different scientific societies have proposed a multifactorial approach to type 2 diabetes.The objective of this study was to identify the degree of control of glycosylated haemoglobin (HbA1c) and of cardiovascular risk factors in type 2 diabetic patients, using the GedapS 2004 guidelines, and to analyse the type and intensity of drug treatment. METHODS: This cross-sectional, multicentre, epidemiological study was conducted in a primary care setting in Vallès Occidental South, Catalonia. Data were collected of 393 patients aged 18 and above who were diagnosed with diabetes mellitus type 2. Biodemographic and clinical data, cardiovascular risk factors, associated cardiovascular disease, and treatment were assessed. Descriptive and multivariable analysis with logistic regression was realized. RESULTS: A total of 392 patients with a mean age of 66.8 years (SD = 10.6) (45.4% male patients) were analyzed. The duration of diabetes was 8.4 years (SD = 7.6). The degree of multifactorial control of risk factors was only 2.6%, although in more than 50% individual cardiovascular risk factor was controlled, except for LDL cholesterol (40.6%) and systolic blood pressure (29.6%). Furthermore, only 13.0% of subjects had an optimal BMI, 27.5% an optimal waist circumference. Treatment for diabetes was prescribed in 82.7% of patients, for hypertension 70.7%, for dyslipidaemia 47.2% and 40.1% were taking antiplatelets. CONCLUSION: Over 50% of type 2 diabetic patients presented optimal control of the majority of individual cardiovascular risk factors, although the degree of multifactorial control of diabetes was insufficient (2.6%) and should be improved. Drug treatment can be intensified using a larger number of combinations, particularly in patients with target organ damage and associated clinical cardiovascular disease.

Cluster randomized trial in smoking cessation with intensive advice in diabetic patients in primary care. ITADI Study.

BACKGROUND: It is a priority to achieve smoking cessation in diabetic smokers, given that this is a group of patients with elevated cardiovascular risk. Furthermore, tobacco has a multiplying effect on micro and macro vascular complications. Smoking abstinence rates increase as the intensity of the intervention, length of the intervention and number and diversity of contacts with the healthcare professional during the intervention increases. However, there are few published studies about smoking cessation in diabetics in primary care, a level of healthcare that plays an essential role in these patients. Therefore, the aim of the present study is to evaluate the effectiveness of an intensive smoking cessation intervention in diabetic patients in primary care. METHODS/DESIGN: Cluster randomized trial, controlled and multicentric. Randomization unit: Primary Care Team. STUDY POPULATION: 546 diabetic smokers older than 14 years of age whose disease is controlled by one of the primary care teams in the study. OUTCOME MEASURES: Continuous tobacco abstinence (a person who has not smoked for at least six months and with a CO level of less than 6 ppm measured by a cooximeter) , evolution in the Prochaska and DiClemente's Transtheoretical Model of Change, number of cigarettes/day, length of the visit. Point of assessment: one- year post- inclusion in the study. INTERVENTION: Brief motivational interview for diabetic smokers at the pre-contemplation and contemplation stage, intensive motivational interview with pharmacotherapy for diabetic smokers in the preparation-action stage and reinforcing intevention in the maintenance stage. STATISTICAL ANALYSIS: A descriptive analysis of all variables will be done, as well as a multilevel logistic regression and a Poisson regression. All analyses will be done with an intention to treatment basis and will be fitted for potential confounding factors and variables of clinical importance. Statistical packages: SPSS15, STATA10 y HLM6. DISCUSSION: The present study will try to describe the profile of a diabetic smoker who receives the most benefit from an intensive intervention in primary care. The results will be useful for primary care professionals in their usual clinical practice. TRIAL REGISTRATION: Clinical Trials.gov Identifier: NCT00954967.
