RESUMO
Potential environmental determinants of BP and hypertension in older adults are far less known than their lifestyle risk factors. Manganese (Mn) is an essential element for life that may induce changes in blood pressure (BP), but the direction of the association is unclear. We aimed to examine the association of blood manganese (bMn) with 24-h-based brachial, central BP (cBP), and pulse-wave velocity (PWV). With this purpose, we analyzed data from 1009 community-living adults aged >65 years without BP medication. bMn was measured using inductively-coupled plasma-mass spectrometry and 24-h BP with validated devices. The association of bMn (median: 6.77 µg/L; IQR: 5.59-8.27) with daytime brachial and central systolic (SBP) and with diastolic BP (DBP) was non-linear, with BP increases up to around the median of Mn and then stabilization or slight rightward decrease. Mean BP differences (95% confidence interval) comparing Mn Q2 to Q5 (vs Q1 quintile) for brachial daytime SBP were 2.56 (0.22; 4.90), 3.59 (1.22; 5.96), 3.14 (0.77; 5.51) and 1.72 (-0.68; 4.11) mmHg, respectively; and 2.22 (0.70, 3.73), 2.55 (1.01, 4.08), 2.45 (0.91; 3.98), and 1.68 (0.13; 3.24), respectively, for DBP. Daytime central-pressures showed a similar dose-response relationship with bMn as daytime brachial-pressures. The association with nighttime BP was linearly positive for brachial BPs, and only increasing for Q5 for cBP. Regarding PWV, a tendency to significant linear increase along bMn levels was observed (p-trend = 0.042). The present findings extend the scarce evidence on the association between Mn and brachial BP to 2 other vascular parameters, suggesting Mn levels as a candidate risk factor for increasing levels of both brachial and cBPs in older adults, yet further research is needed with larger cohort studies in adults at all age ranges.

Falls are a major health problem in older adults, but their relationship with alcohol consumption in this population remains unclear. In a cohort with 2170 older adults followed up for 3.3 years, both moderate drinking and the Mediterranean drinking pattern were associated with a lower risk of falls and injurious falls. INTRODUCTION: This study aims to examine the association between certain patterns of alcohol consumption, including the Mediterranean drinking pattern (MDP), and the risk of falls in older adults. METHODS: A prospective cohort with 2170 community-dwelling individuals aged ≥60 years was recruited in Spain in 2008-2010 and followed up through 2012. At baseline, participants reported alcohol consumption and, at the end of follow-up, their falls during the previous year. The MDP was defined as moderate alcohol consumption (threshold between moderate and heavy intake was 40 g/day for men and 24 g/day for women) with preference for wine and drinking only with meals. Analyses were conducted with negative binomial or logistic regression, as appropriate, and adjusted for the main confounders. RESULTS: Compared with never drinkers, the number of falls was lower in moderate drinkers (incidence rate ratio (95% confidence interval), 0.79 (0.63-0.99)) and drinkers with MDP (0.73 (0.56-0.96)). Also, moderate drinkers and those with MDP showed a lower risk of ≥2 falls (odds ratio (95% confidence interval), 0.58 (0.38-0.88) and 0.56 (0.34-0.93), respectively) and of falls requiring medical care (0.67 (0.46-0.96) and 0.61 (0.39-0.96), respectively). CONCLUSION: Both moderate drinking and the MDP were associated with a lower risk of falls and injurious falls in older adults. However, sound advice on alcohol consumption should balance risks and benefits.

OBJECTIVE: Review of some of the best-known biological and non-biological complementary/alternative therapies/medicines (CAM) and their relationship with blood pressure (BP) and hypertension (HT). SEARCH STRATEGY: Narrative review assessing a recent series of systematic reviews, meta-analyses, and clinical trials published in recent years, focusing on the effects of CAM on BP and HT. SELECTION OF STUDIES: We searched EMBASE, MEDLINE, Cochrane Library and Google Scholar, obtaining a total of 4336 articles, finally limiting the search to 181 after applying filters. SYNTHESIS OF RESULTS: Some studies on biological therapies show some usefulness in BP reduction with an adequate benefit-risk balance, although there is a scarcity of high-quality trials that support these results. Some mind-body therapies have shown hypothetical benefit; in contrast, others lack robust evidence. CONCLUSIONS: Although some therapies present a reasonable risk-benefit ratio, they should in no case replace pharmacological treatment when indicated.

BACKGROUND AND AIM: No previous study has assessed the association between major dietary patterns and the risk of coronary heart disease (CHD) in a large cohort from a Mediterranean country. METHODS AND RESULTS: We studied prospectively 40,757 persons, aged 29-69 years, participating in the Spanish cohort of the EPIC study. Food consumption was collected between 1992 and 1996 with a validated history method. Individuals were followed-up until 2004 through record linkage with hospital discharge registers, population-based registers of myocardial infarction, and mortality registers to ascertain CHD events (fatal and non-fatal acute myocardial infarction or angina requiring revascularization). Two major dietary patterns were identified from factor analysis. The first pattern was labeled as Westernized, because of the frequent consumption of refined cereals and red meat; the second was called the evolved Mediterranean pattern, because of the frequent intake of plant-based foods and olive oil. During a median follow-up of 11 years, 606 CHD events were ascertained. No association was found between the Westernized pattern and CHD risk. In contrast, the score for the evolved Mediterranean pattern was inversely associated with CHD risk (p for trend = 0.0013); when compared with the lowest quintile of the evolved Mediterranean pattern score, the multivariable hazard ratios for CHD were 0.77 (95% confidence interval 0.61-0.98) for the second quintile, 0.64 (95% CI 0.50-0.83) for the third quintile, 0.56 (95% CI 0.43-0.73) for the fourth quintile, and 0.73 (95% CI 0.57-0.94) for the fifth quintile. CONCLUSION: A Mediterranean diet, as consumed in this study population, was associated with a lower risk of CHD.

OBJECTIVES: To examine the type of cardiovascular disease (CVD) and treatment and achievement of treatment goals in blood pressure and lipids in hypertensive patients in primary care. PATIENTS AND METHODS: A cross-sectional study of all medical records of hypertensive patients, from which patients with antihypertensive treatment who visited the 25 Primary Health Care Centers of the 6(th) sanitary district of Madrid during 2008 were selected. RESULTS: From a total of 92,079 patients, 19,501 (21 2%) with an arterial hypertension had a previous diagnosis of CVD (23.9% in males and 19.1% in females). In hypertensive with CVD, the most frequent diagnosis and their proportion in males and females were: ischemic heart disease 35.6% (43.7%/27.6%), atrial fibrillation 29.5% (25%/33.9%), stroke 24% (22%/26.7%), chronic renal disease 15.7% (18.2%/13.2%), heart failure 15.3% (10.4%/20.2%) and peripheral artery disease 7.5% (8.7%/6.4%) (P<.05). Antihypertensive drugs, lipid-lowering drugs and antiplatelet therapy were used more often by males, with women predominating in the prescription of diuretics and angiotensin receptor blockers and anticoagulants, (P<.05).The proportion of patients with blood pressure<140/90 mmHg was 60.5% and 59.1%, and that of LDL-cholesterol <100mg/ dl was 40.4% y 31% (P<.005), in males and females, respectively. CONCLUSIONS: In almost all the 20,000 patients with CVD studied, substantial gender differences in the prevalence, therapy and achievements of goals in the different types of CVD were observed. These results suggest the convenience of homogenization of the computerized registries at the present, for monitoring results over time, with no need of continuous sampling-based studies.

Hypertension (HYP) is the first cause of death and disability worldwide. In Spain, one in 3 adults was hypertensive in 2010 (62% in those >65 years in 2017). Despite improvement in HYP management over time, only half of treated hypertensive patients are adequately controlled, which translates in 30,000 annual cardiovascular deaths attributable to HYP. Among modifiable determinants of lack of blood pressure (BP) control in Spain are: (a) the white-coat phenomenon (accounting for 20-50% of apparent lack of control) due to not using ambulatory BP monitoring (ABPM, use ≈20%) or self-measurement of home BP (HBPM, use ≈60%) for confirming HYP diagnosis; (b) insufficient patients adherence to BP-lowering lifestyles (e.g., only 40% of hypertensive patients have a sodium intake <2.4g/day, or follow a weight reduction advice), and (c) use of drug monotherapy (≈50% currently), usually insufficient to achieve an optimal control. It is necessary to implement strategies to monitor the evolution of the proportion of subjects with HYP with reasonable national update, to promote population's knowledge of their BP figures and of other cardiovascular risk factors, to improve the degree of HYP control and vascular risk in Spain.

Hypertension is the most important risk factor for global disease burden. Detection and management of hypertension are considered as key issues for individual and public health, as adequate control of blood pressure levels markedly reduces morbidity and mortality associated with hypertension. Aims of these practice guidelines for the management of arterial hypertension of the Spanish Society of Hypertension include offering simplified schemes for diagnosis and treatment for daily practice, and strategies for public health promotion. The Spanish Society of Hypertension assumes the 2018 European guidelines for management of arterial hypertension developed by the European Society of Cardiology and the European Society of Hypertension, although relevant aspects of the 2017 American College of Cardiology/American Heart Association guidelines and the 2020 International Society of Hypertension guidelines are also commented. Hypertension is defined as a persistent elevation in office systolic blood pressure ≥ 140 and/or diastolic blood pressure ≥ 90 mmHg, and assessment of out-of-office blood pressure and global cardiovascular risk are considered of key importance for evaluation and management of hypertensive patients. The target for treated blood pressure should be < 130/80 for most patients. The treatment of hypertension involves lifestyle interventions and drug therapy. Most people with hypertension need more than one antihypertensive drug for adequate control, so initial therapy with two drugs, and single pill combinations are recommended for a wide majority of hypertensive patients.

BACKGROUND: Selenium (Se) is a trace element with a narrow safety margin. OBJECTIVES: To evaluate the cross-sectional and longitudinal dose-response association between Se exposure and measures of impaired physical function and disability in older adults. DESIGN: NHANES 2011-2014 cross-sectional (US, n = 1733, age ≥60 years) and Seniors-ENRICA-2 2017-2019 cross-sectional and longitudinal (Spain, n = 2548 and 1741, respectively, age ≥65 years) data were analyzed. Whole blood and serum Se levels were measured using inductively coupled plasma-mass spectrometry. Lower-extremity performance was assessed with the Short Physical Performance Battery, and muscle weakness with a dynamometer. Incident mobility and agility limitations, and disability in instrumental activities of daily living (IADL) were ascertained with standardized questionnaires. Analyses were adjusted for relevant confounders, including physical activity. Results across studies were pooled using random-effects meta-analysis. RESULTS: Meta-analyzed odds ratios (95% confidence interval) per log2 increase in whole blood Se were 0.54 (0.32; 0.76) for weakness, 0.59 (0.34; 0.83) for impaired lower-extremity performance, 0.48 (0.31; 0.68) for mobility limitations, 0.71 (0.45; 0.97) for agility limitations, and 0.34 (0.12; 0.56) for disability in at least one IADL. Analyses for serum Se in NHANES showed similar results. Findings suggest the inverse association with grip strength is progressive below 140 µg/L (p-value for non-linear trend in the Seniors-ENRICA-2 study = 0.13), and above 140 µg/L (p-value for non-linear trend in NHANES = 0.11). In the Seniors-ENRICA-2 cohort, with a 2.2 year follow-up period, a doubling in baseline Se levels were associated with a lower incidence of weakness [odds ratio (95% confidence interval): 0.45 (0.22; 0.91)], impaired lower-extremity performance [0.63 (0.32; 1.23)], mobility [0.43 (0.21; 0.91)] and agility [0.38 (0.18; 0.78)] limitations. DISCUSSION: In US and Spanish older adults, Se concentrations were inversely associated with physical function limitations. Further studies are needed to elucidate underlying mechanisms.

OBJECTIVE: Prevalence of cardiovascular disease is high in schizophrenia. Our aim is to estimate the prevalence of cardiovascular risk factors (CVRF) among schizophrenia patients. METHOD: National cross-sectional study in patients diagnosed with schizophrenia under treatment with second generation antipsychotics and admitted to short-stay hospitalisation units. RESULTS: A sample of 733 consecutively admitted patients was enrolled; the most prevalent CVRFs were smoking 71% (95% CI: 67-74%) and hypercholesterolemia 66% (61-70%) followed by hypertriglyceridemia 26% (26-32%), hypertension 18% (15-21%) and diabetes 5% (4-7%). Metabolic syndrome showed 19% (95% CI: 16-23%) prevalence or, according to updated definitions (Clin Cornerstone 7 [2005] 36-45), 24% (95% CI: 20-28%). The rate of patients within the high-risk range of a 10-year fatal cardiovascular event was 6.5%. CVRFs under routine management were diabetes (60%), hypertension (28%) and, to a lesser extent, dyslipemia (14%). Treatment for CVRFs was associated to gender, men for hypertension OR = 25.34, p < 0.03 and women for diabetes OR = 0.02, p < 0.03. CONCLUSION: We found that CVRFs in schizophrenia were prevalent and under-diagnosed, and thus with insufficient therapeutic management.

Conventional blood pressure (BP) measurement in clinical practice is the most used procedure for the diagnosis and treatment of hypertension (HT), but is subject to considerable inaccuracies due to, on the one hand, the inherent variability of the BP itself and, on the other hand biases arising from the measurement technique and conditions, Some studies have demonstrated the prognosis superiority in the development of cardiovascular disease using ambulatory blood pressure monitoring (ABPM). It can also detect "white coat" hypertension, avoiding over-diagnosis and over-treatment in many cases, as well detecting of masked hypertension, avoiding under-detection and under-treatment. ABPM is recognised in the diagnosis and management of HT in most of international guidelines on hypertension. The present document, taking the recommendations of the European Society of Hypertension as a reference, aims to review the more recent evidence on ABPM, and to serve as guidelines for health professionals in their clinical practice and to encourage ABPM use in the diagnosis and follow-up of hypertensive subjects. Requirements, procedure, and clinical indications for using ABPM are provided. An analysis is also made of the main contributions of ABPM in the diagnosis of "white coat" and masked HT phenotypes, short term BP variability patterns, its use in high risk and resistant hypertension, as well as its the role in special population groups like children, pregnancy and elderly. Finally, some aspects about the current situation of the Spanish ABPM Registry and future perspectives in research and potential ABPM generalisation in clinical practice are also discussed.

To examine the association between several eating behaviours and obesity, data were taken from a cross-sectional study conducted with 34,974 individuals aged 25-64 years, representative of the non-institutionalised Spanish population. Obesity was defined as BMI >or= 30 kg/m2. Study associations were summarised with OR obtained from logistic regression, with adjustment for socio-demographic and lifestyle factors. The results showed that those skipping breakfast were more likely to be obese, both in men (OR 1.58; 95 % CI 1.29, 1.93) and women (OR 1.53; 95 % CI 1.15, 2.03). Moreover, obesity was more prevalent in those having only two meals per day than in those having three or four meals in men (OR 1.63; 95 % CI 1.37, 1.95) and women (OR 1.30; 95 % CI 1.05, 1.62). Also, snacking was associated with obesity in women (OR 1.51; 95 % CI 1.17, 1.95). However, no association was observed between obesity and having one or more of the main meals away from home, in either sex. In conclusion, skipping breakfast and eating frequency were associated with obesity. The lack of association between eating away from home and obesity is in contrast to most previous research conducted in Anglo-Saxon countries. Differences in the type of establishment frequented when eating out or in the characteristics of restaurant customers in a Mediterranean population might explain these conflicting results.

The American College of Cardiology (ACC) and the American Heart Association (AHA) have recently published their guidelines for the prevention, detection, evaluation, and management of hypertension in adults. The most controversial issue is the classification threshold at 130/80mmHg, which will allow a large number of patients to be diagnosed as hypertensive who were previously considered normotensive. Blood pressure (BP) is considered normal (<120mmHg systolic and <80mmHg diastolic), elevated (120-129 and <80mmHg), stage 1 (130-139 or 80-89mmHg), and stage 2 (≥140 or ≥90mmHg). Out-of-office BP measurements are recommended to confirm the diagnosis of hypertension and for titration of BP-lowering medication. In management, cardiovascular risk would be determinant since those with grade 1 hypertension and an estimated 10-year risk of atherosclerotic cardiovascular disease ≥10%, and those with cardiovascular disease, chronic kidney disease and/or diabetes will require pharmacological treatment, the rest being susceptible to non-pharmacological treatment up to the 140/90mmHg threshold. These recommendations would allow patients with level 1 hypertension and high atherosclerotic cardiovascular disease to benefit from pharmacological therapies and all patients could also benefit from improved non-pharmacological therapies. However, this approach should be cautious because inadequate BP measurement and/or lack of systematic atherosclerotic cardiovascular disease calculation could lead to overestimation in diagnosing hypertension and to overtreatment. Guidelines are recommendations, not impositions, and the management of hypertension should be individualized, based on clinical decisions, preferences of the patients, and an adequate balance between benefits and risks.
RESUMO
The early and accurate diagnosis of hypertension is essential given its importance in the development of cardiovascular disease. The boundaries between normal blood pressure (BP) and hypertension are arbitrary and based on the benefits of treating exceeding those of not treating. Conventional BP measurement at the clinic only offers information of a particular time and presents multiple biases dependent on inherent variability of BP and measurement technique itself. Multiple studies have demonstrated the prognosis superiority in the development of cardiovascular disease of ambulatory blood pressure monitoring (ABPM), allows detection of white coat hypertension, avoiding overdiagnosis and overtreatment, and the detection of patients with masked hypertension who are at risk of underdetection and undertreatment. ABPM also assess nightime BP and circadian variability, providing additional prognostic value. ABPM is recognized in the diagnosis of hypertension in 2011 British NICE Guidelines, very argued at the 2013 European Society of Hypertension guidelines, and recommended in the US Preventive Services Task Force in 2015, 2016 Canadian Guidelines and the 2016 Spanish Program of Preventive Activities and Health Promotion (PAPPS). Its generalization is likely to be only a matter of time.

Hypertension (HT) is the most important risk factor in the development of cardiovascular disease. Classically diagnosis and management have been based on conventional office blood pressure (BP) but it has as main limitation that only offers information of a particular time and presents multiple biases dependent on inherent variability of blood pressure and measurement technique itself. Ambulatory blood pressure monitoring (ABPM) consists of performing multiple measurement of blood pressure, performed automatically, outside the medical setting, during the normal activities of the individual and in a 24-hour period. Multiple studies have demonstrated the prognosis superiority in the development of cardiovascular disease of ABPM, it allows detection of white coat HT as well, avoiding overdiagnosis and overtreatment and the detection of patients with masked H T, who contrarily are at risk of underdetection and undertreatment. Also it provides nighttime BP and circadian variability that provides additional prognostic value. © 2017 SEHLELHA. Published by Elsevier España, S.L.U. All rights reserved.

Hypertension (HT) is the first cause of death and disability worldwide. One in 3 adults in Spain is hypertensive (66% in those > 60 years). Despite improvement in hypertension management over time, only half of treated hypertensive patients are adequately controlled. This translates in 40,000 annual cardiovascular deaths attributable to H T. Among modifable determinants of lack of blood pressure (BP) control in Spain are: a) the white coat phenomenon (accounting for 20-50% of false lack of control) due to not using ambulatory BP monitoring (current use, 20%) or self-BP measurement (use, 60%) for confirming HT diagnosis; b) insufficient patients adherence to BP reducing lifestyles (e.g., only 40% of hypertensive patients have a sodium intake < 2.4 g/day, or follow a weight reduction advice), and c) use of drug monotherapy (≈50%), usually insufficient to achieve adequate control. © 2017 SEHLELHA.

This study assesses the association of childhood socioeconomic circumstances, height, and obesity with components of blood pressure. We selected 4009 people representative of the Spanish population aged 60 years and older, and estimated systolic blood pressure (SBP), diastolic blood pressure (DBP), and pulse pressure (PP) according to childhood social class, height, and obesity. No association was found between childhood social class and blood pressure. SBP showed an inverse gradient and DBP a direct gradient with height, although an independent association between height and DBP was found only in women. Stature was independently associated with increased DBP in women with central obesity, but there was no association between height and DBP in women without central obesity. Short stature was independently associated with increased PP. Body mass index and waist-to-hip ratio were independently associated with increased DBP in women, and waist-to-hip ratio was independently associated with increased PP in men, while waist circumference was independently associated with increased DBP and increased PP in women. These results do not support the assumed effect of socioeconomic circumstances in early life on blood pressure, which may depend on the context and/or study population. The relations observed between height and blood pressure support the hypothesis that PP could be a mediator of the association between short stature and increased cardiovascular risk. The relationship between obesity measures and components of blood pressure reinforces the recommendation to reduce body weight in order to reduce blood pressure.

This study analyzed the relationship between blood pressure and all-cause mortality according to objectively measured walking speed in a Mediterranean population-based sample of older persons. We used data from the longitudinal 'Peñagrande' Cohort Study, initiated in 2008 in a sex- and age-stratified random sample of 1250 people aged ⩾65 years living in Madrid (Spain). A total of 814 individuals participated in the first study wave. The average of two standardized blood pressure readings was used. Walking speed was measured over a 3-m walk and classified as faster (⩾0.8 m s(-1)) or slower. A total of 314 individuals were slower walkers, 475 were faster walkers and 25 did not complete the walk test. Cox proportional hazards models stratified by walking speed were used to assess the association between blood pressure and all-cause death. Non-linear relationship between BP and mortality was explored by a restricted cubic spline analysis. There were 171 deaths from study entry through 31 March 2013. Systolic blood pressure <140 mm Hg and diastolic blood pressure <90 mmHg were associated with higher mortality than blood pressure values above 140 and 90 mm Hg, respectively, but this association reached statistical significance only for systolic blood pressure and only in the slower walkers. In conclusion, systolic blood pressure levels <140 mm Hg were found associated with higher risk of total mortality among slower walkers in an old Spaniard population cohort.

Distribution of blood pressure (as per US Joint National Committee VI classification and staging criteria) plus awareness, treatment, and control of hypertension were studied in a representative Spanish population sample of 2021 persons (age range, 35 to 64 years). Pressure was determined in accordance with World Health Organization guidelines. A total of 45.1% of subjects were hypertensive (>/=140/>/=90 mm Hg or undergoing drug therapy); 12% had isolated systolic hypertension, and 8.7% had isolated diastolic hypertension. Pulse pressure was 48.7 mm Hg. Heart rate was 81.4 bpm in untreated hypertensives and 78.9 bpm in normotensives (P<0.05). A substantial proportion of the community burden of blood pressure was attributable to stage 1 (28.3% of subjects), the most frequent category of hypertension, and to the high-normal blood pressure group (17% of subjects). A percentage breakdown showed that among hypertensives, 44.5% were aware of their condition; of these, 71.9% were undergoing drug therapy, and of those being treated, only 15.5% were controlled (5% of hypertensives). Not only are these figures consistent with the fact that Spain has a higher cerebrovascular mortality than other countries such as the United States, but they represent a great potential for improvement, particularly among those groups registering relatively worse data (younger men, rural residents, and unskilled professionals). A decrease of only 1 to 4 mm Hg in average blood pressure could reduce the prevalence of hypertension in Spain by 12.4% to 15.4%.

OBJECTIVE: To determine whether there is a relationship between season of birth and adult blood pressure, as a possible early determinant of later blood pressure. DESIGN: We studied 572 men, aged 45-64 years, whose blood pressure was measured in standardized manner as part of a nation-wide survey in Spain. To analyse the seasonal variation in blood pressure, a linear regression was performed, adjusting for age, height, body mass index, occupation and rural or urban residence. RESULTS: We found seasonal variation in mean systolic blood pressure, with maxima in adults born in autumn and winter, and minima in those born in spring and summer. The greatest difference in systolic blood pressure occurred between adults born in spring (134.1 mmHg) and those born in autumn (140.3 mmHg). After adjustment, the difference in means between spring and autumn was 5.9 mmHg (95% confidence interval 0.7 to 11.1 mmHg, P = 0.03). CONCLUSIONS: This study demonstrated differences in systolic blood pressures of adult men according to the season of their birth. Although this relationship is compatible with several hypotheses, the difference found between spring and autumn, partially independent of some other factors, might indicate that the extent of early exposure to sunlight is implicated in determining later blood pressure. This needs further investigation.

BACKGROUND: There is an apparent paradox in the geographical distribution of ischaemic heart disease (IHD) mortality in Spain. The Mediterranean regions, those with the lowest consumption of total and saturated fats, register the highest mortality due to IHD. This paper seeks to explain this paradox by examining the provincial distribution of IHD mortality in Spain and their known risk factors, dietetic and non-dietetic. METHODS: The study was based on data aggregated by province. Mortality data were taken from official vital statistics, while data on diet and other lifestyle habits were obtained from representative, large-scale, sample-based population surveys. Correlation and multiple regression analyses were run on standardized IHD mortality ratios for the period 1983-1987 and potential dietetic and non-dietetic determinants in 1989-1981. RESULTS: Intake of total lipids, saturated and polyunsaturated fatty acids, fish and wine were lower in Spain's southern and eastern provinces. Consumption of wine, fish, chicken, dairy products, vegetables and blond cigarettes, as well as unemployment, explained 53% of the variation in IHD mortality. Consumption of fish and wine alone exhibited a statistically significant relationship (P < 0.05) with IHD mortality. Moderate consumption of wine was negatively associated with IHD mortality, whereas heavy consumption patterns revealed a positive association. CONCLUSIONS: Based on correlation analyses of ecological data, lower consumption of wine and fish may explain the apparent paradox of higher IHD mortality in the presence of a lower intake of saturated fats in Spain's Mediterranean regions.
