Japan has been experiencing ever more rapid socioeconomic development and changes in eating habit, especially in children, since the end of the Second World War. These occurrences (westernized life style) have greatly affected the growth of Japanese. Nutrition is the most important factor in promoting the physical growth in childhood during food supply shortage, and for a relatively short term the secular trend in linear growth will reach a plateau if the food supply is adequate, but the secular trend is also limited. Since the condition for this limitation should be comprised by genetic factors, we are most interested in investigating and analyzing these genetic factors in the near future. Overeating adversely affects growth in childhood, with most common representatives of these ill effects being atherogenic risk factors such as obesity, hypertension and hypercholesterolaemia.

The medical effects of modest weight reduction (approximately 10% or less) in patients with obesity-associated medical complications were reviewed. The National Library of Medicine MEDLINE database and the Derwent RINGDOC database were searched to identify English language studies that examined the effects of weight loss in obese patients with serious medical complications commonly associated with obesity (non-insulin dependent diabetes mellitus (NIDDM or type II), hypertension, hyperlipidemia, hypercholesterolemia, and cardiovascular disease). Studies in which patients experienced approximately 10% or less weight reduction were selected for review. Studies indicated that, for obese patients with NIDDM, hypertension or hyperlipidemia, modest weight reduction appeared to improve glycemic control, reduce blood pressure, and reduce cholesterol levels, respectively. Modest weight reduction also appeared to increase longevity in obese individuals. In conclusion, a large proportion of obese individuals with NIDDM, hypertension, and hyperlipidemia experienced positive health benefits with modest weight loss. For patients who are unable to attain and maintain substantial weight reduction, modest weight loss should be recommended; even a small amount of weight loss appears to benefit a substantial subset of obese patients.

There is little debate that an elevated plasma cholesterol level, specifically an elevated plasma LDL cholesterol level, increases cardiovascular disease risk. Data from inter- and intrapopulation studies have clearly demonstrated that as total and LDL cholesterol levels increase, cardiovascular disease risk increases. Although this relationship is generally accepted, the specifies of the relationship generate debate. Relevant questions pertain to the actual level of plasma cholesterol at which cardiovascular disease risk is increased, whether the relationship holds true across all age groups and both sexes, and what contributions plasma HDL levels and the plasma LDL/HDL ratio make to cardiovascular disease risk independent of plasma LDL levels. Irrespective of these uncertainties, the evidence that elevated plasma LDL cholesterol levels constitute an independent risk factor for cardiovascular disease has been a major component in studying the genetic and environmental factors involved in hypercholesterolemia. Epidemiologic data reveal relationships between a number of dietary elements and elevated plasma cholesterol levels with the strongest relationships between dietary fatty acids, plasma cholesterol levels, and cardiovascular disease incidence. The data from a variety of epidemiologic investigations, both cross-cultural and cross-sectional, indicate that plasma total cholesterol levels are increased by saturated fat intake and obesity. HDL cholesterol levels are decreased by intakes of low-fat, high-carbohydrate diets, a high BMI, and lack of activity and increased by intake of dietary fat, alcohol, and physical activity. Controlled clinical trials have provided verification of these epidemiologic observations in practically every case.(ABSTRACT TRUNCATED AT 250 WORDS)

The combined syndrome of android (upper body) obesity, diabetes, hyperlipidaemia and hypertension is discussed in terms of a deranged endocrine regulation of metabolism. The syndrome is characterized by insulin insensitivity and an increased control of metabolism by cortisol. The antagonism between the two hormones appears to be partly responsible for the hyperglycaemia, hypertriglyceridaemia and hypercholesterolaemia. The synergism between insulin and cortisol in stimulating energy deposition, associated with a decreased effect of corticotropin-releasing factor in stimulating energy expenditure, is likely to contribute to the development of obesity. The efficacy of D-fenfluramine in treating the obese-diabetic-hyperlipidaemic-hypertensive syndrome probably depends on its actions on the serotoninergic system in the hypothalamus which both decreases food consumption and tends to normalize hormonal balance through the hypothalamic-pituitary-adrenal axis.

In 1987, a cardiovascular risk profile was obtained on 836 workers of the National Electricity Co in Santiago. There were 714 males and 125 females, the mean age was 45 years (ES +/- 0.3). Hypertension (systolic pressure > 160 or diastolic > 90 mmHg) was present in 17% of subjects, hypercholesterolemia (> 240 mg/dl or > 220 mg/dl associated to 2 other risk factors) in 17%, obesity (> 20% above ideal weight) in 33% and 29% were smokers. An advice to stop smoking, changes in the casino menu and hypertension, obesity and hypercholesterolemia's control programs were offered. These were attended by 108 hypertensives, 141 subjects with hypercholesterolemia and 104 obese individuals with an attendance rate of 64%, 75 and 77% respectively. Measurements repeated 2 years later revealed a reduction in diastolic pressure of 3.3 +/- 1.1 mmHg (p < 0.004) only in adherent subjects. Cholesterol levels were reduced by 24 +/- 3 mg/dl (p < 0.001) with no differences for non participants, adherent and non adherent subjects. Adherent obese subjects reduced their weight by 2.2 +/- 0.4 kg (p < 0.001). There was no change in the number of smokers.

The present study analyzes the influence of the nutritional status on the functional capability of 11 institutionalized elderly living in Madrid (Spain). Nutritional status was evaluated by dietetic, anthropometric, hematological and biochemical data and functional status was evaluated considering adiposity, strength in hands and legs bent and stretched and flexibility. The most important nutritional problems that conditional functional wastages are obesity, hypercholesterolemia and protein and micronutrient deficiency. The adverse influence of obesity and hypercholesterolemia on the functional capacity of the elderly is shown by the inverse relationship between flexibility and strength in hands and legs with the adiposity degree, with the thickness of skin folds and the cholesterolemia. In reference to the diet's influence, there are positive correlations between food intake and most of the nutrients with hand and legs strength, and there are statistical significances for proteins, iron, zinc, magnesium and pyridoxine, and also for vitamin C, niacin, thiamin, folic acid and vitamin E. For blood values, the mayor correlation exists between functional parameters and iron, ferritin and vitamin C levels. Our results contribute to confirm the influence of nutrition on the functional capacity of the influence of nutrition on the functional capacity of the elderly and manifest the necessity of improving the elderly's diet, to prevent micronutrient deficiency and also the necessity of increasing their physical activity. Both measures will mean an important help for sanitary and functional improvement of the elderly.

The author analyses distant results of the Polish vascular prostheses implantation to 227 patients with aorto-iliac occlusive disease. Eighty two (29.6%) patients died within 5 years following the operation. Therefore, an analysis of the distant results of therapy included 145 patients. An excellent result was achieved in 20.7% of the treated patients, satisfactory result in 53.9%, no improvement or worsening in 20.7% of cases. Statistically significant relationship between the degree of pre-operative ischemia and outcome of surgery has been noted. Considering blood hypertension, diabetes mellitus, obesity, hypercholesterolemia, and tobacco smoking prior to and after surgery as risk factors, no statistically significant relationship between the distant result of the treatment and the number of risk factor in a single patient has been observed.

Coronary heart disease (CHD) is still relatively uncommon in the black population of South Africa. We embarked on a study to determine the prevalence of risk factors leading to CHD in the black population of Durban. The study sample was selected from patients attending a dental clinic at a hospital. A total of 458 patients (age range 16-69 years) was studied. The prevalence of CHD was 2.4%. The percentage prevalences of selected risk factors were: hypertension (blood pressure > or = 140 mmHg systolic and/or > or = 90 mmHg diastolic) 28% (31.9% for males, 25.4% for females); protective levels of high-density lipoprotein/total cholesterol > or = 20%, 81.3%; diabetes mellitus 4.9% for males, 2.9% for females; smoking > or = 10 cigarettes per day 28.1% for males, 3.4% for females; obesity 3.7% for males 22.6% for females. We found the Minnesota Coding System for electrocardiographic changes of CHD and the Rose questionnaire to be unreliable for eliciting CHD in blacks. Hypercholesterolaemia is less common, and this may explain the low incidence of CHD in blacks. Epidemics of CHD as seen in Indian, coloured and white South Africans can still be prevented in the black population, but preventive measures must be instituted rapidly.

In the hypertensive patient, the presence of other cardiovascular risk factors, particularly smoking, hypercholesterolemia, obesity, and diabetes, greatly influences the prognosis. In many patients, these other risk factors are linked, perhaps by adverse effects of pressure on endothelial function. The newer antihypertensive agents may have better effects on prognosis by ameliorating these other risk factors, as well as lowering pressure. We await trials to see if this promise is fulfilled.

Several epidemiological studies have shown that obesity is related to the mortality from cardiovascular disease. In this study, the epidemiology of obesity and the correlation between body mass index and other cardiovascular risk factors was studied in a representative sample of the adult population of Catalonia. It was obtained a random sample (n = 704) of the adult population of Catalonia aged 15 or more years. Height and weight were measured and body mass index (BMI) was calculated (height in Kg/weight2 in m2). Obesity was defined as a BMI greater than 30, and overweight as a BMI from 25 to 30. In the first 314 participants, it was determined the concentration of total cholesterol, cholesterol-HDL and triglyceride, and it was measured the blood pressure. The correlation between BMI and other cardiovascular risk factors was analysed. The study was carried out in 1989. The mean of BMI increased with age in both sexes. BMI was significantly higher in men (26 kg/m2) than women (25 kg/m2). The prevalence of obesity was of 12% in both men and women, and the prevalence of overweight was of 48.5% in men and 38% in women. The prevalence of arterial hypertension, hypercholesterolemia and diabetes was greater individuals with obesity, with differences statistically significant for hypertension (odds ratio of 3.26). The multiple logistic regression analysis showed that the association between obesity and hypertension was not statistically significant (OR adj. = 2.09), when the effect of the other risk factors, the age and sex were controlled.(ABSTRACT TRUNCATED AT 250 WORDS)
