“…The CAREMA cohort consists of participants of two large monitoring projects in the Netherlands living in the Maastricht region: the monitoring project on cardiovascular risk factors (PPHVZ) 1987-1991 [18] and the monitoring project on chronic disease risk factors (MORGEN Project) 1993-1997, [19] including the transition year (1992) between these projects. Each year, a random sample of people aged 20-59 years was selected from the municipal registries of Maastricht and surrounding communities: Eijsden, Margraten, Meerssen, and Valkenburg aan de Geul.…”

“…The most important reasons to be only registered in the CIS-based registry for cases with CHD, acute myocardial infarction, and unstable angina pectoris were as follows: a different discharge diagnosis in the HDR-based registry (68, 59, and 75%, respectively), mostly ICD-9 codes 413.90 (other and unspecified angina pectoris) and 414.00 (coronary atherosclerosis), a diagnosis based on outpatient files (18,6, and 21%, respectively), or a hospital admission in another Dutch hospital (1, 3, and 0%, respectively), or in a foreign hospital (4, 9, and 1%, respectively). All cases with CHD, acute myocardial infarction and unstable angina pectoris that were registered only in the HDR-based registry had a diagnosis of another (11, 100, and 40%, respectively) or no cardiovascular disease (89, 0, and 60%, respectively) according to the CIS-based registry.…”

Validity of coronary heart diseases and heart failure based on hospital discharge and mortality data in the Netherlands using the cardiovascular registry Maastricht cohort study

Incidence rates of cardiovascular diseases are often estimated by linkage to hospital discharge and mortality registries. The validity depends on the quality of the registries and the linkage. Therefore, we validated incidence rates of coronary heart disease (CHD), acute myocardial infarction, unstable angina pectoris, and heart failure, estimated by this method, against the disease registry of the cardiovascular registry Maastricht cohort study. The cohort consists of 21,148 persons, born between 1927 and 1977, who were randomly sampled from Maastricht and surrounding communities in 1987-1997. Incident cases were identified by linkage to the Netherlands causes of death registry and either the hospital discharge registry (HDR) or the cardiology information system (CIS) of the University Hospital Maastricht. Sensitivities and positive predictive values were calculated using the CIS-based registry as gold standard. Relatively high sensitivities and positive predictive values were found for CHD (72 and 91%, respectively) and acute myocardial infarction (84 and 97%, respectively). These values were considerably lower for unstable angina pectoris (53 and 78%, respectively) and heart failure (43 and 80%, respectively). A substantial number of cases (14-47%) were found only in the CISbased registry, because they were missed or miscoded in the HDR-based registry. As a consequence, the incidence rates in the HDR-based registry were considerably lower than in the CIS-based registry, especially for unstable angina pectoris and heart failure. Incidence rates based on hospital discharge and mortality data may underestimate the true incidence rates, especially for unstable angina pectoris and heart failure.

“…The contribution of nutritional factors to the development of hypertension is well recognized, in particular with reference to the four cations sodium, potassium, calcium and magnesium, [1][2][3][4][5][6] both in terms of nutrient intake quantities as well as frequency of consumption of food group. 7,8 The link between hypertension and osteoporosis have not received as much attention, in terms of common underlying pathogenetic mechanism, perhaps as both conditions are common with ageing.…”

Dietary intake, blood pressure and osteoporosis

et al. 2008

Both hypertension and osteoporosis have common underlying nutritional aetiology, with regards to dietary cations intake. We tested the hypothesis that sodium intake reflected in urinary Na/Cr and blood pressure would be negatively associated with bone mineral density (BMD), whereas other cations may have opposite associations. Subjects were part of a study of bone health in 4000 men and women aged 65 years and over. A total of 1098 subjects who were not on antihypertensive drugs or calcium supplements and who provided urine samples were available for analysis. Logistic regression was used to examine associations between total hip and lumbar spine BMD, age, gender, body mass index (BMI), urinary Na/Cr, K/Cr, calcium and magnesium intake, systolic blood pressure and diastolic blood pressure. Total hip BMD was inversely associated with age, being female and urinary Na/Cr, and positively associated with BMI, urine K/Cr and dietary calcium intake. Lumbar spine BMD was inversely associated with being female and urinary Na/Cr, and positively associated with BMI, dietary calcium intake and SBP. We conclude that sodium intake, reflected by urinary Na/Cr, is the major factor linking blood pressure and osteoporosis as shown by the inverse relationship with BMD. The findings lend further emphasis to the health benefits of salt reduction in our population both in terms of hypertension and osteoporosis.

“…3,4 However, the results of the different studies were inconsistent. [5][6][7][8][9][10][11][12][13][14][15][16] Some methodological problems were considered to be responsible for this heterogeneity. For example, differences in the method of sampling, dietary data collection and assessing calcium intake are possible causes.…”

A cross-sectional study on association of calcium intake with blood pressure in Japanese population

et al. 2002

To investigate the association of calcium intake independently of other nutrients already known as predictors of hypertension, a cross-sectional study was carried out on the same population in Japan as used for the INTERSALT study. Dietary calcium intake was estimated from a 1-day 24-h recall. Sodium and potassium intakes were evaluated by 24-h urinary excretion. Data from 476 subjects aged 20-59 years, 230 men and 246 women, were analysed. The mean dietary calcium intake ranged from 557 to 608 mg/day among men, and from 528 to 639 mg/day among women. Among men, the pooled estimate of the regression coefficients of blood pressure (mm Hg) per 100 mg increase of calcium intake, adjusted for age and body mass index (BMI), were −0.42 mm Hg for systolic blood pressure (SBP) and −0.35 mm Hg for diastolic blood pressure (DBP), but
