Excess Weight in Spain: Current Situation, Projections for 2030, and Estimated Direct Extra Cost for the Spanish Health System.

INTRODUCTION AND OBJECTIVES: Excess weight promotes the development of several chronic diseases and decreases quality of life. Its prevalence is increasing globally. Our aim was to estimate the trend in excess weight between 1987 and 2014 in Spanish adults, calculate cases of excess weight and its direct extra costs in 2006 and 2016, and project its trend to 2030. METHODS: We selected 47 articles in a systematic literature search to determine the progression of the prevalence of overweight, nonmorbid obesity, and morbid obesity and average body mass index between 1987 and 2014. We projected the expected number of cases in 2006, 2016, and 2030 and the associated direct extra medical costs. RESULTS: Between 1987 and 2014, the prevalence of overweight, obesity, and morbid obesity increased by 0.28%/y (P=.004), 0.50%/y (P <.001) and 0.030%/y (P=.006) in men, and by 0.10%/y (P=.123), 0.25%/y (P=.078), and 0.042%/y (P=.251) in women. The mean body mass index increased by 0.10 kg/m2/y in men (P <.001) and 0.26 kg/m2/y in women (significantly only between 1987 and 2002, P <.001). We estimated 23 500 000 patients with excess weight in 2016, generating 1.95 billion €/y in direct extra medical costs. If the current trend continues, between 2016 and 2030, there will be 3 100 000 new cases of excess weight, leading to 3.0 billion €/y of direct extra medical costs in 2030. CONCLUSIONS: Excess weight in Spanish adults has risen since the creation of population registries, generating direct extra medical costs that represent 2% of the 2016 health budget. If this trend continues, we expect 16% more cases in 2030 and 58% more direct extra medical costs.

Validity Assessment of Low-risk SCORE Function and SCORE Function Calibrated to the Spanish Population in the FRESCO Cohorts.

INTRODUCTION AND OBJECTIVES: To assess the validity of the original low-risk SCORE function without and with high-density lipoprotein cholesterol and SCORE calibrated to the Spanish population. METHODS: Pooled analysis with individual data from 12 Spanish population-based cohort studies. We included 30 919 individuals aged 40 to 64 years with no history of cardiovascular disease at baseline, who were followed up for 10 years for the causes of death included in the SCORE project. The validity of the risk functions was analyzed with the area under the ROC curve (discrimination) and the Hosmer-Lemeshow test (calibration), respectively. RESULTS: Follow-up comprised 286 105 persons/y. Ten-year cardiovascular mortality was 0.6%. The ratio between estimated/observed cases ranged from 9.1, 6.5, and 9.1 in men and 3.3, 1.3, and 1.9 in women with original low-risk SCORE risk function without and with high-density lipoprotein cholesterol and calibrated SCORE, respectively; differences were statistically significant with the Hosmer-Lemeshow test between predicted and observed mortality with SCORE (P < .001 in both sexes and with all functions). The area under the ROC curve with the original SCORE was 0.68 in men and 0.69 in women. CONCLUSIONS: All versions of the SCORE functions available in Spain significantly overestimate the cardiovascular mortality observed in the Spanish population. Despite the acceptable discrimination capacity, prediction of the number of fatal cardiovascular events (calibration) was significantly inaccurate.

Age and sex inequalities in the prescription of evidence-based pharmacological therapy following an acute coronary syndrome in Portugal: the EURHOBOP study.

AIM: To assess the proportion of patients receiving pharmacological therapy for secondary prevention after an acute coronary syndrome (ACS) in Portugal and to identify age and sex inequalities. DESIGN: Retrospective cohort study. METHODS: We studied 747 episodes of ST-segment elevation myocardial infarction (STEMI) and 1364 of non-ST-segment elevation ACS (NSTE-ACS), within a sample of ACS cases consecutively discharged from 10 Portuguese hospitals, in 2008-2009. We estimated adjusted odds ratios (OR) for the association of age and sex with the use of each pharmacological treatment. RESULTS: In STEMI and NSTE-ACS patients, the proportion of patients discharged with aspirin was 96 and 88%, clopidogrel 91 and 78%, aspirin+clopidogrel 88 and 71%, beta-blockers 80 and 76%, angiotensin-converting enzyme (ACE) inhibitors/ARB 82 and 80%, statins 93 and 90%, 3-drug (aspirin/clopidogrel+beta-blocker+statin) 76 and 69%, and 5-drug treatment (aspirin+clopidogrel+beta-blocker+ACE inhibitor/ARB+statin) 61 and 48%, respectively. Among STEMI patients, those aged ≥80 years were substantially less often discharged with clopidogrel (OR 0.22, 95% confidence interval, CI, 0.08-0.56), aspirin+clopidogrel (OR 0.34, 95% CI 0.15-0.76), beta-blockers (OR 0.39, 95% CI 0.18-0.82), 3-drug (OR 0.41, 95% CI 0.21-0.83), and 5-drug treatments (OR 0.44, 95% CI 0.23-0.83) than those <60 years; women were less likely to be discharged with aspirin+clopidogrel (OR 0.52, 95% CI 0.29-0.91). Among NSTE-ACS patients, those aged ≥80 years were much less likely to be discharged with beta-blockers (OR 0.58, 95% CI 0.36-0.93), statins (OR 0.35, 95% CI 0.19-0.64), and 3-drug treatment (OR 0.47, 95% CI 0.30-0.75); sex had no significant effect on treatment prescription. CONCLUSIONS: The vast majority of younger patients were discharged on evidence-based secondary preventive medications, but only half received the 5-drug combination. Recommended therapies were substantially underprescribed in older patients.

Assessment of the value of a genetic risk score in improving the estimation of coronary risk.

BACKGROUND: The American Heart Association has established criteria for the evaluation of novel markers of cardiovascular risk. In accordance with these criteria, we assessed the association between a multi-locus genetic risk score (GRS) and incident coronary heart disease (CHD), and evaluated whether this GRS improves the predictive capacity of the Framingham risk function. METHODS AND RESULTS: Using eight genetic variants associated with CHD but not with classical cardiovascular risk factors (CVRFs), we generated a multi-locus GRS, and found it to be linearly associated with CHD in two population based cohorts: The REGICOR Study (n=2351) and The Framingham Heart Study (n=3537) (meta-analyzed HR [95%CI]: ~1.13 [1.01-1.27], per unit). Inclusion of the GRS in the Framingham risk function improved its discriminative capacity in the Framingham sample (c-statistic: 72.81 vs.72.37, p=0.042) but not in the REGICOR sample. According to both the net reclassification improvement (NRI) index and the integrated discrimination index (IDI), the GRS improved re-classification among individuals with intermediate coronary risk (meta-analysis NRI [95%CI]: 17.44 [8.04; 26.83]), but not overall. CONCLUSIONS: A multi-locus GRS based on genetic variants unrelated to CVRFs was associated with a linear increase in risk of CHD events in two distinct populations. This GRS improves risk reclassification particularly in the population at intermediate coronary risk. These results indicate the potential value of the inclusion of genetic information in classical functions for risk assessment in the intermediate risk population group.

[Trends in leisure time physical activity practice in the 1995-2005 period in Girona]. / Tendencias en la práctica de actividad física en el tiempo libre en el periodo 1995-2005 en Girona.

INTRODUCTION AND OBJECTIVES: The aims of the study were: to describe the distribution of physical activity practice; to determine the prevalence and trends of sedentary lifestyle in the population aged 35 to 74 years of Girona in the 1995-2005 period; and to identify the variables associated to sedentary lifestyle at the population level. METHODS: Data from three independent population-based cross-sectional studies undertaken in 1995 (n=1419), 2000 (n=2499), and 2005 (n=5628) were analyzed. Physical activity was measured using the Minnesota Leisure Time Physical Activity questionnaire. Sedentary lifestyle was defined as an energy expenditure in moderate physical activity (4-5.5 METs) <675 kcal/week or <420 kcal/week in intense PA (≥ 6 METs). Logistic regression was used to determine the variables associated with sedentary lifestyle. RESULTS: The age-standardized prevalence of sedentary lifestyle was 53.8%, 39.5%, and 32.6% in 1995, 2000, and 2005 respectively. The prevalence of sedentary lifestyle has decreased especially in women older than 50 years living in the urban areas. An increase in light and moderate physical activity practice in men older than 50 years and in light physical activity practice in women older than 50 years was observed. Female gender, age, smoking and lower educational level were associated with a higher prevalence of sedentary lifestyle. CONCLUSIONS: Prevalence of sedentary lifestyle has decreased in the 1995-2005 period in Girona, especially in women, but is still high. Health promotion programs should include physical activity practice as a key element and should take into account gender and social inequalities.

Prevalence of cardiovascular risk factors in men with stable coronary heart disease in France and Spain.

BACKGROUND: Cigarette smoking, raised blood pressure, unfavourable lipid concentrations, diabetes and - more indirectly - obesity, are responsible for most coronary heart disease events in developed and developing countries. AIMS: The objective of our study was to compare prevalence, treatment and control of cardiovascular risk factors in two samples of men with stable coronary heart disease, recruited in France and Spain. METHODS: Standardized measurements of body mass index, systolic and diastolic blood pressures, plasma lipids, glycaemia, and smoking were collected and drug use was registered. Cross-sectional comparisons were made between French and Spanish samples. RESULTS: Data from 982 individuals were analysed (420 French and 562 Spanish men). Current smoking was more frequent in Spain (p<0.001), whereas hypertension and uncontrolled blood pressure were more frequent in France (p<0.001). Mean concentrations of low-density lipoprotein cholesterol and triglycerides were significantly higher in France (p<0.001). No significant differences were observed regarding obesity, high-density lipoprotein cholesterol and diabetes. More than 97% of participants presented with at least one of the following conditions: hypertension, dyslipidaemia, diabetes, obesity or smoking. Antiplatelet agents, calcium inhibitors, diuretics and hypoglycaemic drugs were used more frequently in France, whereas angiotensin-converting enzyme inhibitors and lipid-lowering treatments were used more frequently in Spain. CONCLUSION: Prevalence of cardiovascular risk factors is high among French and Spanish patients with stable coronary heart disease, with differences between countries regarding the distribution of the various risk factors. A great proportion of patients do not reach the recommended levels for risk factor control.

Waist circumference and impaired fasting glucose screening in a Mediterranean population.

We evaluate the merits of routine waist circumference measurements for screening of impaired fasting glucose (IFG). Waist circumference and body mass index showed a strong association with the risk of IFG. The present data indicate the need for routine anthropometric measurements in clinical practice screening for IFG.

Qualitative assessment of previous evidence and an updated meta-analysis confirms lack of association between the ESR1 rs2234693 (PvuII) variant and coronary heart disease in men and women.

BACKGROUND: Coronary heart disease (CHD) is the leading cause of mortality worldwide. CHD clusters in families but this familial aggregation remains largely unexplained. ESR1 is a candidate gene for CHD although recent meta-analyses of the rs2234693 variant reported inconsistent evidence for association with myocardial infarction (MI) in men. The objectives of this study were to perform a qualitative and a quantitative assessment of all evidence to date regarding this association. METHODS: We performed structured literature searches for studies addressing the association between the ESR1 rs2234693 and CHD. We assessed the quality of these studies collectively and individually according to recently published guidelines on the reporting and interpretation of genetic association studies. We also performed a meta-analysis of all studies to date, including a sample of MI cases and controls from our region. RESULTS: The qualitative assessment indicated that many studies met a low proportion of the criteria proposed by the current guidelines. No significant association between ESR1 rs2234693 and MI was observed in our sample or in the meta-analysis (16 studies; N approximately 32,000; OR approximately 1). Strong between-study heterogeneity was largely explained by a quality score based on the quality criteria. Studies that reported significant associations were generally of poorer quality. CONCLUSION: We confirm the lack of association between the ESR1 rs223469 and CHD, and show that inconsistencies between previous studies is explained by differences in their quality.

[Validity of the MONICA cardiovascular questionnaire compared with clinical records]. / Validez del cuestionario cardiovascular MONICA comparado con la historia clínica.

OBJECTIVE: To assess the validity of the questionnaire Multinational Monitoring of Trends and Determinants in Cardiovascular Disease (MONICA) compared with clinical records. METHODS: A descriptive, prospective, multicenter study was performed within the framework of the Peripheral Arterial Disease Study (PERART) in 3,329 persons aged >50 years old. The sample was selected by simple random sampling in 32 primary health care centers. The diagnoses included were acute myocardial infarction, angina pectoris, cerebrovascular disease, hypertension, diabetes mellitus, and hypercholesterolemia. Treatment variables were also considered (antihypertensive, lipid-lowering and hypoglycemic agents or insulin, as well as antiplatelet or anticoagulant agents). The sensitivity, specificity, predictive values, and kappa index were computed to test the validity of the MONICA questionnaire. RESULTS: The mean age was 65 years (SD 8.9) and 54.8% were women. The sensitivity of the questionnaire was >90% for all the variables apart from angina pectoris (89.9%) and cerebrovascular disease (86.5%). Specificity was also >90%, except for angina pectoris (88.3%) and hypercholesterolemia (77.5%). The positive predictive value was >90% for all the treatments; >80% for angina pectoris, acute myocardial infarction and hypertension; 79.4% for cerebrovascular disease; 79.1% for hypercholesterolemia and 73.4% for diabetes mellitus. The negative predictive value was >90% for all the variables. The kappa indexes were >0.80 for all the variables apart from hypercholesterolemia (0.69) and diabetes mellitus (0.79). CONCLUSIONS: The MONICA cardiovascular questionnaire is valid in the assessment of cardiovascular disease, risk factors and treatments in patients aged >50 years old.

Patterns of use and effectiveness of early invasive strategy in non-ST-segment elevation acute coronary syndromes: an assessment by propensity score.

BACKGROUND: The patterns of use and the benefit of an early invasive strategy (EIS) in patients with non-ST-segment elevation acute coronary syndrome in a real-life population are not well established. METHODS: All consecutive patients hospitalized because of non-ST-segment elevation acute coronary syndrome between November 2004 and June 2005 in 32 randomly selected hospitals were prospectively included. Patients were stratified by their baseline risk profile using the Global Registry of Acute Coronary Events (GRACE) risk score in 2 groups. Inhospital mortality and 1- and 6-month mortality or rehospitalization for acute coronary syndromes were analyzed. To ensure optimal adjustment propensity score, conventional logistic regression and Cox regression were used. RESULTS: Of 2,856 patients analyzed, 1,616 (56%) had low/intermediate risk (GRACE140). Patients who underwent EIS had lower risk than those who did not (GRACE score 128.2+/-41 vs 138.5+/-43, P<.001). Coronary angiography facility emerged as the strongest predictor of EIS (odds ratio [OR] 13.7 [95% CI 7.1-25]). Patients who underwent EIS had lower rate of the 6-month outcome in both the whole population (9% [95% CI 6.6-11.9] vs 14% [95% CI 12.5-15.6], P=.003) and in high-risk patients (16.5% [95% CI 11-23] vs 23.6% [95% CI 20.8-26.5], P=.04). However, this benefit of EIS was not apparent after statistical adjustment in the whole population (OR 0.8, CI 0.55-1.1, P=.17) or in high-risk patients (OR 0.7, CI 0.46-1.1, P=.16). CONCLUSIONS: In a real-life population, EIS was mainly performed in patients of low/intermediate risk. An obvious benefit of this strategy could not be found.

Analysis of inequalities in secondary prevention of coronary heart disease in a universal coverage health care system.

OBJECTIVE: The purpose of this study was to analyse whether differences exist in social class or education level in coronary heart disease (CHD) secondary prevention and in cardiovascular risk factor control in a universal coverage health care system. DESIGN: Cross-sectional multi-centre study. PARTICIPANTS AND SETTING: 1022 CHD patients recruited from residents in the catchment areas covered by 23 primary health care facilities in Catalonia, Spain. MAIN OUTCOME MEASURES: Demographic data, cardiovascular co-morbidity, smoking, blood pressure, fasting blood glucose, triglycerides, total cholesterol, HDL and LDL cholesterol, body mass index (BMI), drug therapy used for secondary prevention, educational level, and social class based on occupation. RESULTS: Patients at the lowest educational level were more frequently women, older, and diabetic. Patients in the middle educational level were more frequently smokers than those in the highest or the lowest level (24.7, 8.7, and 12.0%, respectively; P = 0.008) and had better systolic blood pressure levels (125 mmHg (15), 135 mmHg (16), and 134 mmHg (17), respectively; P = 0.001). All educational levels and social classes had similar adjusted rates of risk factor control. Therapeutic management was also similar among all educational levels and social classes, after adjusting for confounders. CONCLUSIONS: CHD patients in the lower SES received similar treatment for secondary prevention and achieved similar control of risk factors. No social inequalities were found in secondary prevention in CHD patients using the National Health System in Spain.

Association of time elapsed since the last coronary event with health services utilization.

BACKGROUND: Patients with chronic illness use health services more often but little is known about the use that coronary heart disease patients make of primary care. OBJECTIVE: To determine whether the time elapsed and the perceived quality of life following a major acute coronary event are associated with utilization rate of primary care services. DESIGN: Cross-sectional, multicentre study. SETTING: Twenty-three primary care health centres in Catalonia (Spain). PARTICIPANTS: Patients aged 30-80 years who had suffered a major coronary event in the previous 6 years. MAIN OUTCOME MEASURES: The number of consultations with the general practitioner during the year before the beginning of the study was noted and patients who consulted nine or more times were considered frequent attenders. The time elapsed since the last major coronary event was categorized using the median (2 years) as a cut-off value. The SF-12 quality of life questionnaire was administered. RESULTS: A total of 1022 patients with coronary heart disease were included. The median number of consultations with a general practitioner within the previous year was 5 (range 0 - 36). Patients with a shorter time elapsed since the last coronary event were seen more often by their general practitioner. The probability of being frequent attender was 24% Iower among patients with less recent coronary events (adjusted odds ratio: 0.76, 95% confidence interval: 0.69 - 0.85, p < 0.001). Quality of life scores were similar in frequent and non-frequent attenders. No relationship between comorbidity and frequent attendance was found. CONCLUSIONS: The shorter time elapsed since the last coronary event was an important factor related with frequent attendance in coronary heart disease patients regardless of cardiovascular comorbidity, and perceived quality of life.

Acute myocardial infarction population incidence and in-hospital management factors associated to 28-day case-fatality in the 65 year and older.

BACKGROUND AND OBJECTIVES: The myocardial infarction (MI) incidence rate, prognosis and hospitalisation rate in the population 65 and over are rarely studied. We sought to determine MI hospitalisation and incidence rates, and 28-day case-fatality, in the 65 year and older population, and to analyse whether their management and prognosis differed from that of younger patients. METHODS: All residents in Gerona (Spain) older than 24 years with suspected fatal or non-fatal MI were investigated and included in a population registry. RESULTS: MI mortality, incidence, and case-fatality dramatically increased with age after 64. Smoking, thrombolysis, antiplatelet and betablocker drug use, coronary angiograms, and coronary revascularisation decreased with age. The risk of death of patients between 75 and 84 years (OR: 4.15, 95% confidence interval, CI: 1.70-10.15) and between 85 and 94 years (OR: 4.68, 95% CI: 1.62-13.52) was higher than in the 34-64 years age group, independently of any patient characteristic. CONCLUSIONS: The magnitude of the impact of MI in the elderly at population and hospital levels is substantially higher than in those younger than 65 years of age. After this age patients receive less treatments and procedures than their younger counterparts.

Relationship of socioeconomic status with cardiovascular risk factors and lifestyle in a Mediterranean population.

BACKGROUND: Socioeconomic status greatly affects cardiovascular risk factors and lifestyle. Aim of the study To analyse the relationship between socioeconomic status and both cardiovascular risk factors and behavioural variables. AIM OF THE STUDY: To analyse the relationship between socioeconomic status and both cardiovascular risk factors and behavioural variables. METHODS: The present random sample of 838 men and 910 women of the 25 to 74 year old general population of Gerona according to the 1991 census, included cardiovascular risk factor measurements (total cholesterol, LDL cholesterol, HDL cholesterol, triglycerides, glycaemia, systolic blood pressure, diastolic blood pressure, body mass index, waist to hip ratio, and waist circumferences) and evaluation of dietary habits, alcohol consumption, smoking, and leisure-time physical activity with corresponding questionnaires. RESULTS: In this study, we used lifestyle factors (leisure-time physical activity, tobacco consumption, and alcohol drinking habits) in addition to dietary habits to determine whether changes in these factors correlate with the socioeconomic status, classified as degree of educational level, in a representative Spanish Mediterranean population. Multiple linear regression analysis adjusted for several confounders revealed a direct association of LDL-cholesterol (p = 0.03) and body mass index (p = 0.02) with low levels of educational status in men and women, respectively. A higher educational status was directly (p = 0.04) related to the smoking status in women. The two composite dietary scores, indicating overall dietary quality and cardiovascular protecting properties, were not associated with low socioeconomic status in our population. CONCLUSION: Dietary habits, alcohol drinking, and leisure-time physical activity seems not to be affected by educational status in either gender. This finding might partially explain the relationship between cardiovascular risk factors and socioeconomic status in our population. The importance of cultural values in the rural area of the Spanish province seems to be the stronger factor compared with education.
