Twenty-year cardiovascular and all-cause mortality trends and changes in cardiovascular risk factors in Gubbio, Italy: the role of blood pressure changes.

Aims: In an observational population study that lasted 20 years, the relationships between mortality trends and changes in cardiovascular risk factor levels were examined.

Methods And Results: In the town of Gubbio, in central Italy, population surveys for measurement of cardiovascular risk factors were performed 20 years apart. In a subset of the initial cohort (1927 men and 2333 women), mortality data were collected for 20 years.

Enhanced Na-Li countertransport: a marker of inherited susceptibility to type 2 diabetes.

Unlabelled: Introduction The association between type 2 diabetes and hypertension has long been described, but the mechanisms remain unclear. Na-Li countertransport (Na-Li CT) activity is viewed as a marker of inherited pre-disposition to hypertension, especially if associated with other metabolic abnormalities. Aim To evaluate whether enhanced Na-Li CT activity is a predictor of type 2 diabetes.

Is there a relationship between left ventricular mass and plasma glucose and lipids independent of body mass index? Results of the Gubbio Study.

Background And Aims: The association between left ventricular (LV) mass (M) and variables described as features of the insulin resistance syndrome, such as obesity and measures o lipid and carbohydrate metabolisms, has been reported in hypertensives. The aim of the present study was to investigate in a large, population based group of non hypertensive people, the prevalence of LV hypertrophy (H) and the relationship of LVM with some of the variables described in the insulin resistance syndrome, independently of obesity. For this reason we investigated the normotensive subjects in the age range 45-54 yrs (n = 435) of the total population of participants in the Gubbio Population Study.

Relationship between plasma insulin and left ventricular mass in normotensive participants of the Gubbio Study.

Background: There is substantial but not conclusive evidence that insulin resistance is related to left ventricular mass (LVM) in hypertensive individuals. To what extent this association is mediated by the relationship between plasma insulin and body size and build is still debated, and is poorly explored in nonhypertensive people.

Objective: To explore the relationship between insulin or insulin resistance and LVM in a population-based sample of nonhypertensive participants of the Gubbio Study.

Serum uric acid for short-term prediction of cardiovascular disease incidence in the Gubbio population Study.

Objective: The Gubbio Study is an Italian population study measuring risk factors for and incidence of major cardiovascular diseases. This analysis investigates the association of serum uric acid with the incidence of coronary and cardiovascular events.

Methods: A population sample of 2469 men and women aged 35-74 years, free from major cardiovascular diseases and in whom serum uric acid was measured in 1983 along with other standard risk factors, were followed up for 6 years and the incidence of coronary heart disease (CHD) and all cardiovascular atherosclerotic (CVD) events, both fatal and non-fatal, was computed.

Pulse pressure and isolated systolic hypertension: association with microalbuminuria. The GUBBIO Study Collaborative Research Group.

Background: The long-term risk of end-stage renal disease is high in persons with isolated systolic hypertension, that is, those with an elevation of pulse pressure and not of diastolic pressure. Other data suggest that pulse pressure is a predictor of the hypertension-induced organ damage. Microalbuminuria is considered an early sign of glomerular damage caused by hypertension.

Prospective analysis of traits related to 6-year change in sodium-lithium countertransport. Gubbio Population Study Research Group.

Sodium-lithium countertransport (Na-Li CT) activity in red blood cells relates cross-sectionally and longitudinally to blood pressure and hypertension. Lifestyle and metabolic factors relate cross-sectionally to this sodium transporter. The aim of this study was to conduct a prospective analysis of 6-year Na-Li CT change and of traits related to Na-Li CT change.

Microalbuminuria in nondiabetic adults: relation of blood pressure, body mass index, plasma cholesterol levels, and smoking: The Gubbio Population Study.

Background: Evidence exists that cardiovascular risk factors influence progression toward end-stage renal failure. We tested the hypothesis that in nondiabetic middle-aged adults without macroalbuminuria, cardiovascular risk factors are related to urinary albumin excretion and prevalence of microalbuminuria, a sign of early nephropathy.

Methods: Cross-sectional analysis of data for 1567 participants in The Gubbio Population Study (677 men and 890 women), aged 45 to 64 years, without macroalbuminuria, without diabetes mellitus, and with fasting plasma glucose levels of less than 7.

Baseline sodium-lithium countertransport and 6-year incidence of hypertension. The Gubbio Population Study.

Background: Sodium-lithium countertransport (Na-Li CT) activity is high in persons with hypertension. This study investigated whether high Na-Li CT relates to development of hypertension.

Methods And Results: At the baseline visit of the Gubbio Population Study, 4210 people of the 5376 surveyed were 18 to 74 years old; of these, 1599 were hypertensive (systolic pressure > or = 140 mm Hg, or diastolic pressure > or = 90 mm Hg, or on antihypertensive drug therapy).

Sodium-lithium countertransport and blood pressure change over time: the Gubbio study.

Sodium-lithium countertransport activity in red blood cells relates to blood pressure (BP) and the prevalence of hypertension. This study investigated in adults the relation of sodium-lithium (Na-Li) countertransport to BP change from baseline to 6-year follow-up. In the Gubbio Population Study, 4210 men and women were 18 to 74 years old at baseline (1983-1986), and 3766 had a valid baseline Na-Li countertransport measurement; of these, 2729 were reexamined at 6 years of follow-up (1989-1992) and made up the study cohort.

Urinary sodium to potassium ratio and urinary stone disease. The Gubbio Population Study Research Group.

The relation was investigated of urinary sodium to potassium ratio in first morning voided urine (spot urine) to urinary stone disease in 3,625 men and women aged 25 to 74 years participating in the baseline examination of the Gubbio Population Study. History of urinary stone disease (excretion of stone, and/or radiographic or ultrasonic evidence of urinary stone, and/or operation for urinary stone removal) was reported by 127 individuals (3.50%).
