In a health examination survey of more than 2,000 middle-aged men the prevalence of hypertension, defined as supine DBP greater than or equal to 105 mmHg and including those on treatment, was 7.5%. Half of the hypertensives were untreated. A satisfactory BP control was present in 27.6% of the total hypertensive population. Untreated hypertensives had a higher relative body weight and a greater skinfold thickness, indicating a greater degree of obesity, than a population sample from the same survey. They also had more hyperuricaemia, hypertriglyceridaemia and hyperinsulinaemia, fasting as well as during i.v. glucose tolerance test. However, when the hypertensives were compared to normotensive, weight-matched controls, most of these differences were eliminated. The findings indicate that the metabolic disturbances in hypertensives are associated with overweight and suggest that weight reduction might be beneficial not only for the BP but also for correcting the metabolic pattern.

A random sample of 2,854 subjects aged 35-64 was examined in the town of Vicenza (Italy) as part of the 'Hypertension Management Audit Project'. Pearson's correlation coefficient and multivariate analysis considering systolic and diastolic blood pressure, age and body mass index (BMI) were performed. SBP was more closely correlated with age than DBP. BMI correlated with both SBP and DBP, but very little with age. Fifty-seven percent of the men had a BMI of 25.5 or more and 49% of the women had a BMI of 24.5 or more. The quality of BP control in the treated patients was worse in the overweight when compared with the lean patients, although overweight and lean patients are treated with the same frequency.

The status of selected cardiovascular risk factors was ascertained in a consecutive sample of 661 (222 men and 439 women) African-American adults who were screened for the Northeast Oklahoma City Cholesterol Education Program, a church-based cholesterol intervention program. Hypertension was present in 48.4% and 44.7% of men and women, respectively. Average systolic blood pressure levels were similar in men and women (132.0 vs 131.5 mm Hg, P = 0.40) although average diastolic blood pressure levels were higher in men (84.0 vs 81.1 mm Hg; P < .0001). A substantial proportion of the screenees were unaware of their hypertension, and blood pressure normalization (SBP < 140 and DBP < 90 mm Hg) was uncommon in drug-treated hypertensives. Average cholesterol levels were slightly higher in women compared to men (206.0 vs 199.6 mg/dL, P = 0.11). The majority of persons with elevated cholesterol levels (> or = 240 mg/dL) were unaware of their condition and were infrequently treated with cholesterol-lowering drugs. Overweight was highly prevalent, was more common with advancing age, and was related to the presence of hypertension in both men and women. In addition, a strong linear relation between overweight and blood pressure was present in both sexes. Overweight was more common in young men (< 35 years old) compared to age-matched women; however, women were increasingly more overweight than men after 35-44 years of age. In fact, by age 65, 90% of the women were overweight. These data indicate an excessive prevalence and high mean levels of modifiable cardiovascular risk factors in these church-attending African-American adults. Because churches are a central institution in most African-American communities, and their congregations appear to have an excessive cardiovascular disease risk factor burden, churches may be appropriate sites for the implementation of community-based risk factor control programs.

We observed 170 obese patients during 55 weeks in order to study the influence of insulin resistance and insulin sensitivity on cardiovascular risk factors in such patients as well as the changes occurring on these subjects as a result of weight loss. At the beginning of the study, the patients were divided into two groups, according to the results of an oral glucose tolerance test (OGTT) performed with 75 g of glucose: Group A, glucose tolerant subjects (n = 81), Group B, glucose intolerant subjects (n = 89). Initially Group B patients showed higher values for fasting blood glucose, 2 h after OGTT, systolic and diastolic blood pressure, cholesterol, triglycerides and cholesterol/HDL-cholesterol ratio when compared to Group A patients (p less than 0.05). Fasting and 1 h-post glucose load serum insulin levels in both Group A and Group B patients were higher than those found out in non over-weight tolerant subjects, but there were no differences between both groups. The serum glucose descent slope after an insulin tolerance test (ITT) was lower for group B than for group A (p less than 0.05), whereas both groups demonstrated lower descent slopes than non overweight tolerant subjects (p less than 0.05). After a 55 weeks follow-up period, the patients in Group A had lost 4.6 +/- 0.7 kg and those in Group B 6.2 +/- 1.1 kg. In both groups, the values for SBP, DBP, FBG, triglycerides and cholesterol/HDL-cholesterol ratio had dropped significantly, with a rise in the HDL-cholesterol level.(ABSTRACT TRUNCATED AT 250 WORDS)

This study examined the relationship between erythrocyte sodium-stimulated lithium countertransport (Na-Li CT) and systolic blood pressure (SBP) response to exercise in 22 white normotensive men (mean age 40.6 years) completing a submaximal (85% of target heart rate) graded exercise tolerance test. These men were assessed to be at risk of hypertension on the basis of a high normal diastolic blood pressure (DBP; 80-89 mmHg), being overweight and having a rapid resting pulse rate. Na-Li CT was positively and significantly associated with the maximal SBP reached during exercise (P less than 0.01) and the lowest SBP achieved during post-exercise supine rest (P less than 0.01). The relationship with resting blood pressure was not significant. Standing DBP was the only resting blood pressure measurement significantly associated with Na-Li CT (P less than 0.05). We found an association between Na-Li CT, a membrane sodium transport system associated with blood pressure and hypertension, and the maximal SBP reached during exercise, a blood pressure measurement predictive of future hypertension, in people with normotensive resting blood pressure. This suggests that altered membrane sodium transport may occur before the establishment of hypertension, and supports the possibility that Na-Li CT may be a risk factor for this disease.

There is evidence of an association between obesity and hypertension. This association occurs more frequently in industrialized population. Weight gain in young adult life is a potent risk factor for later development of hypertension. In this study we used cross-sectional data of medical students, between 17 and 24 years old. The relationship among blood pressure and relative weight were examined through assessment of mean blood pressure levels and prevalence of hypertension. We found that in males, the 21.89% was overweight or obese and in females, the 25.98% was in this range. The blood pressure was greater in males. For all the risk groups, except for the hazardous group about DBP. The regression analysis showed a linear relative weight-blood pressure relation for both sexes and both systolic blood pressure and diastolic blood pressure. The prevalence ratio was greater than 1 in all cases. The observations founded suggest that the mechanism that protect females in young adult life are nulified by the overweight. It's necessary to foment preventive ways against overweight in young adult life because in this age it's possible to revert the higher blood pressure levels. Obesity; hypertension; adolescents.

Between 1991-93 a specially trained team of nurses screened 19,435 subjects from various workforces in different regions of Scotland to identify cardiovascular disease risk factor levels in the Scottish working population. The regions visited provided a wide geographical spread. Name, age, occupation, social class, personal and family history of cardiovascular disease were recorded along with consumption of tobacco, alcohol and salt. Height and weight were measured and Body Mass Index (BMI) calculated; systolic (SBP) and diastolic (DBP) blood pressure, blood glucose and blood cholesterol were also measured. The proportion of social class I-IV in men studied was 49, 22, 22, and 7% respectively and in women 28, 29, 39 and 5%. Fifty two per cent of men and 61% of women had never smoked and 24% of men and 17% of women had previously stopped smoking. Twenty one per cent of both sexes were still smoking. Eighteen per cent of men drank more than 21 units of alcohol per week and 3.4% of women drank more than 14 units per week. Mean values of SBP and DBP increased with age and the percentage with hypertension (> or = 148/90 mm Hg) in men and women was 5% and 24% respectively. Mean BMI was slightly higher in men than women (25.3 & 24.5 respectively) and there was a significant (p < 0.01) rise in BMI with age in both sexes. Forty six per cent of men and 32% of women were classified as overweight (BMI > 25) while 9% of men and 9% of women were classified as obese (BMI > 30).(ABSTRACT TRUNCATED AT 250 WORDS)

The aim of this work was to investigate the changes of cardiac performance by both electrocardiography (ECG) and echocardiography (ECHOc), in addition to anthropometric and hormonal variables before, during and after prolonged total fasting (TF) and re-feeding in an overweight adult man. Physical examination, laboratory and hormonal measurements, ultrasonographic study of body fat distribution, ECG and ECHOc study were performed before during and after 34 days of TF and after 17 days of isocaloric re-feeding. The subject was a 52-year old Caucasian who was overweight with increased abdominal fat content (BMI: 28.6; W/H ratio: 0.95) and increased levels of arterial systolic and diastolic blood pressure (SBP, DBP). HPLC measurements of urinary catecholamine levels (HPLC), ECHOc study of cardiac performance, ultrasonographic study of body fat distribution were performed. The subject starved for 34 days losing 22kg, but after that time he was compelled to re-feed because of nausea and severe vomiting. A marked ketosis (ketonuria > 1200mg/day) was already present after 6 days of TF. After 17 days of TF norepinephrine (NE) and epinephrine (EPI) urinary levels showed a two-fold and nine-fold increase respectively, but they became undetectable at the end of TF. After 17 days of re-feeding catecholamine urinary levels were similar to those measured after 17 days of TF. After both TF and 17-day isocaloric re-feeding we found a decrease of visceral fat content and W/H ratio reached the normal values for age-matched subjects (W/H ratio after TF: 0.80, after re-feeding: 0.80).(ABSTRACT TRUNCATED AT 250 WORDS)

Interest in research on atherosclerosis involving children has been the consequence of confluent evidence that atherogenic process begins in early life and grows silently until the occurrence of clinical events in middle-age or later. We carried out a cross-study in the Mediterranean area on a random sample of a secondary school of Casteldaccia (a farming and fishing village located on the Northern coast of Sicily, East of Palermo), consisting of 186 teen-agers (103 males and 83 females) aged between 10 and 13 years (average age: 11.3 +/- 0.2 years). We determined: total cholesterol, triglycerides, HDL-cholesterol, LDL-Cholesterol, apolipoproteins A1 and B, glycaemia, body mass index (BMI), systolic and diastolic blood pressure. Dietary habits were recorded on two occasions by a weekly diary (of the 7 days food record type) with the collaboration of dieticians. The prevalence of plasma cholesterol levels between 170-200 mg% and exceeding 200 mg% was 24.2% and 12.4% respectively, of overweight (BMI > 25) was 9.7% and of hypertension (SBP > 125 and/or DBP > 85 mmHg) was 8.6%. In comparison with Mediterranean diet according to Euratom study (1969), the following are the most impressive findings: an increase of cholesterol (+54%) and fat intake (+2% of total calories), a reduction of fibre intake (-32%) and an increase of 2S-P difference (+27%) and of total fats/fibre ratio (+53%).

The importance of various factors in explaining geographical BP variations in the UK has been examined among 2,596 men and women living in nine British towns. Associations between BP and potential explanatory variables have been examined first for individual subjects (within-population), and second for towns (between-populations). The factors showing associations with BP that were consistent within-population and between-towns were BMI, urine sodium/potassium ratio (Na/K), alcohol and anxiety at examination for men, and BMI, Na/K and anxiety at examination for women. After adjustment for these factors and age, the male BP differences between the nine towns were reduced from 10.1 mmHg systolic in men (P = 0.001) to 7.1 mmHg (P = 0.04), and from 5.9 mmHg diastolic (P = < 0.0001) to 5.5 mmHg (P < 0.0001). For women, adjustment only marginally reduced the between-town systolic differences from 5.6 mmHg (P = 0.05) to 5.5 mmHg (P = 0.3) and increased the diastolic differences from 3.7 mmHg diastolic (P = 0.03) to 5.0 mmHg (P < 0.0001). It is concluded that BMI, alcohol consumption and the Na/K ratio play an important part in the pattern of male SBP variations in the UK. The factors associated with female geographical differences in BP were less clear, but BMI and Na/K ratio appear to be important. This study has been unable to identify factors associated with geographical differences in DBP, with the possible exception of BMI in men. However, as systolic pressure is recognised to be more strongly associated with cardiovascular outcome than diastolic pressure, it can be recommended that primary prevention strategies aimed at reducing the population mean level of BP should involve efforts to reduce overweight, alcohol consumption and the Na/K ratio.
