The purpose of the present study was to delineate a health profile of professional Danish army personnel. Two-hundred twenty officers, noncommissioned officers, and gunners on active duty at Varde Barracks, housing the South Jutland Artillery Regiment and the Danish Army Artillery School, were asked about their physical and psychological health, interpersonal relations, and working conditions as well as their dietary, drinking, and smoking habits. Measurements were made of resting pulse rate, blood pressure, height, weight, waist and hip girth, and pulmonary function. The ratio of waist-to-hip girth and body mass index (BMI) were calculated. Psychological well-being was evaluated using the 12-item version of the General Health Questionnaire (GHQ). Psychosomatic symptoms were frequently reported, but very few of those surveyed appeared to have psychiatric disorders as measured by the GHQ. Also, somatic health problems were frequently reported, the most frequent being lower-back pain, mild chest pain, and sensory disorders. Differences in interpretation and reporting of "lasting health problems" may explain the relatively high score for this question. The interpersonal relations, both upward and downward in the hierarchy rank order, received high scores. Compared with the general population, alcohol consumption was very low, whereas smoking-in particular heavy smoking-was much more frequent among professional Danish army personnel. Lung function testing showed significantly poorer mean values of forced expiratory volume in 1st second of expiration and mean forced expiratory flow 25 to 75% of forced vital capacity among smokers compared with nonsmokers, although the mean values for the whole group of both smokers and nonsmokers were well above reference values for all lung function parameters. The frequency of moderately overweight individuals (25 < BMI < or = 30) was significantly higher among the male army personnel than in the general population, whereas this was not the case for obesity (BMI > 30). Abdominal obesity, regarded as an independent risk factor for the development of ischemic heart disease, stroke, diabetes, hypertension, and all-cause mortality, was present in 5%, and 3% belonged to the highest-risk group by having a low BMI as well as abdominal obesity.

This study examined, through a randomized controlled trial, the effects of cross-training (combined resistance and endurance exercise) on markers of insulin resistance, (e.g., dyslipidemia, intra-abdominal obesity, hyperinsulinemia, and hypertension), body composition, and performance in hyperinsulinemic individuals. Sedentary adult males characterized as hyperinsulinemic (fasting insulin > 2 OuU.mL-1), randomly assigned to two groups (N = 8 each), completed 14 wk of training at 3 d.wk-1. An endurance-only (E) group performed both continuous cycle exercise and walking (30 min each at 60-70% heart rate reserve). A cross-training (C) group performed both endurance and resistance exercise (8 exercises, 4 sets/exercise, 8-12 repetitions/set) in a single session. Both E and C groups demonstrated similar increases in VO2max (25% and 27%) while only C demonstrated an increase in 1 RM bench press (19%) and leg press (25%). The changes induced by C training were significantly greater than those from E training alone in percent fat (6.9 +/- 1.3 vs 1.4 +/- 1.4), insulin concentration (8.5 +/- 2.7 vs 3.0 +/- 1.3 uU.mL-1), glucose levels (11.1 +/- 2.9 vs 5.9 +/- 2.6 mg.dL-1), HDL-C levels (5.1 +/- 1.3 vs 2.9 +/- 1.6 mg.dL-1), triglyceride concentration (43.8 +/- 13.6 mg.dL-1), and systolic blood pressure (14.6 +/- 5.5 vs 8.3 +/- 6.8 mm Hg). Results indicate that the addition of resistance training to an endurance training program will induce significantly greater differences in markers of insulin resistance and body composition in individuals with hyperinsulinemia than endurance training alone.

At least one-third of Americans are obese, as defined by body mass indexes corresponding to body weight > or = 120% of ideal body weight, and this figure is rising steadily. Women and nonwhites have particularly high rates of obesity. Obesity greatly increases risks for many serious and morbid conditions, including diabetes mellitus, hypertension, dyslipidemia, coronary artery disease, and some cancers. Obesity is clearly associated with increased risk for mortality, but there has been controversy regarding optimal weight with respect to mortality risk. We review the literature concerning obesity and mortality, with reference to body fat distribution and weight gain, and consider potential effects of sex, age, and race on this relation. We conclude that when appropriate adjustments are made for effects of smoking and underlying disease, optimal weights are below average in both men and women; this appears to be true throughout the adult life span. Central obesity, most commonly approximated by the waist-to-hip ratio, may be particularly detrimental, although this requires further study. Weight gain in adulthood is also associated with increased mortality. These observations support public health measures to reduce obesity and weight gain, including recent recommendations to limit weight gain in the adult years to 4.5 kg (10 lb).

First degree relatives of patients with non-insulin-dependent diabetes mellitus (NIDDM) have a 40% risk of developing NIDDM during their lifetime and the risk seems to be greater if the disease is inherited from the mother than from the father. It has also become clear that metabolic abnormalities are demonstrable long before the disease becomes manifest. The prediabetic state is associated with a predisposition to abdominal obesity, insulin resistance, lipid disorders, high blood pressure, and microalbuminuria, ie, the metabolic or insulin resistance syndrome. It is, however, not yet known whether treatment of these abnormalities is able to prevent progression to manifest NIDDM.

A variety of studies indicates that the process of atherosclerosis begins in childhood and progresses during adulthood. Chronic obesity, inadequate caloric intake, and hypertension and smoke, are associated with an increased cardiovascular disease. The aim of this study is to investigate if the presence of some risk factors during adolescence may involve in accelerated atherosclerosis disease. 50 subjects, median age 11 +/- 0.6 SD (27 females, and 23 males) are admitted to the study. After overnight fasting we have investigated: lipoproteina A (nephelometric test), glycemia and insulin baseline and after load 120', tryglycerides, cholesterolo, apolipoproteina A, B, plasma concentrations. In addition to general medical evaluation, anthropometric measurements of weight, height, blood pressure, BMI, overnight ratio were calculated according to Tanner's charts. The means anthropometric and metabolic values in different groups were compared. One group affected with abdominal obesity state (waist-hips ratio > 0.9), the second with mid obesity condition (waist-hip ratio < 0.9). Tryglycerides, cholesterolo, insulin plasma concentrations in both groups were considered similar. However in the first group higher levels of apolipoproteina A (means 102 + 10.2 SD) and lipoproteina A were demonstrated (P = 0.03 in males, P = 0.01 Statview for Mann Whitney test). Childhood is an important period for the development of the atherosclerosis such as the presence of obesity during this time has a very high likelihood of persisting into adulthood. The severity of obesity in adults is greater in those who were obese as adolescents. In accord with other authors we have not observed abnormal tryglicerides and cholesterolo plasma concentrations, which probably are found in adulthood obesity. We believe indeed the risk factors are different in obesity of childhood, atherosclerosis may be induced by high endogenous insulin secretion and abnormal uptake of lipoprotein. However the potential consequence of excessive insulin secretion could be due in part to insulin effects on recruitment of histiocytosis cells during the development of atheroma and through the modulation of hepatic production and peripheral uptake of lipoproteins.

Generalised obesity is a major risk factor for cardiovascular disease, diabetes, hypertension and premature death, but abdominal or central obesity is even more closely related to these. Diabetes causes accelerated atherosclerosis and this results in peripheral vascular and ischaemic heart disease and stroke, major causes of death in diabetics in the Caribbean. Diabetics who have abdominal obesity are therefore at increased risk for these events. 485 patients attending the Diabetes Referral Clinic at the University Hospital of the West Indies, Jamaica, were evaluated for abdominal obesity based on the ratio between their waist and hip measurements. There was an increase in the numbers of diabetics with increasing age. Abdominal obesity was significantly more prevalent among females (90%) than among males (34.9%) (mean 2 = 142; p < 0.0001), and massive obesity was detected in 31.1% of females. However, the prevalence of abdominal obesity among males and females was not significantly age-related. Given the high prevalence of obesity in this clinic population, more precise studies of abdominal obesity associated morbidity in diabetics should be undertaken.

Truncal obesity judged by increased waist-hip ratio (WHR) is an important risk factor for atherosclerosis. One of the mechanisms postulated by which truncal obesity increases coronary risk is high blood pressure (BP). Studies of correlation of WHR with systolic and diastolic BP have shown conflicting results. A study on 443 persons (250 males, 193 females) for WHR measurement during a comprehensive cardiovascular survey in an urban population of Rajasthan was undertaken. The mean WHR in males was 0.90 +/- 0.07 and in females 0.87 +/- 0.08. The median value was 0.91 in males and 0.88 in females. Correlational analysis of WHR with anthropometric and clinical parameters showed that in males there was a positive relationship of WHR with weight (r = 0.11), body mass index (r = 0.13) and systolic (r = 0.11) and diastolic BP (r = 0.11) but not with age and height. In females no significant relationship was seen with these variables. When classified according to the US Fifth Joint National Committee (JNC-V) recommendations for diagnosis of truncal obesity (WHR males > 0.95, females > 0.85) it was seen in 42 (17%) males and 131 (68%) females. Sub-analysis of these two groups showed that mean values of systolic and diastolic BP were not significantly different in truncally obese subjects. However, stratified analysis after classifying WHR in four groups (WHR < 0.85, 0.85-0.89, 0.90-0.95 and > 0.95) showed that in males there was a significantly rising trend of weight, body mass index, systolic and diastolic BP with increasing WHR. WHR of > or = 0.85 was associated with higher systolic and diastolic BP.

The increasing prevalence of traditional atherosclerotic risk factors have been documented in Asia but the real impact on prevalence of coronary heart disease (CHD) remains unclear. Smoking, hypertension, hypercholesterolaemia, diabetes mellitus and obesity are present in only 50% of CHD. In community studies of Chinese in Hong Kong and southern mainland-China, aging, smoking and hypercholesterolaemia were found to have a less impact on endothelial function in the Chinese compared with Caucasians in London and Sydney. As endothelial dysfunction is an early event in atherogenesis, there will be a strong need to search for newer risk factors for CHD in Asia, which may become more important in many Asian countries now in the process of modernization. Recently, heterozygous hyperhomocysteinaemia (with or without folate deficiency) was found to be an independent risk factor for arterial endothelial dysfunction, and hyperhomocysteinaemia in association with smoking was a significant risk factor for premature coronary heart disease in Hong Kong Chinese. Other newer factors which have emerged include folate deficiency, low HDL-cholesterol, insulin resistance, abdominal obesity, Methylene-tetrahydrofolate Reductase and Angiotensin Converting Enzyme gene polymorphism.

Black people in the UK, in the Caribbean, and to a lesser extent in the USA, experience coronary heart disease events at different rates than white people. Despite having higher prevalence of hypertension, cigarette smoking and diabetes, black males have significantly lower coronary heart disease rates than white males, whereas no significant differences have been detected in females. The only known risk factor differences that could account for the difference in CHD rates are higher HDL cholesterol and lower triglycerides that are seen in blacks compared with whites. Obesity and, in particular abdominal obesity, seems to determine TG and HDL cholesterol levels: black males are less centrally obese than whites, while total adiposity and central distribution of fat is more predominant in black females compared with white females. We propose that the less degree of abdominal adiposity observed in black males is related with an increased anti-lipolytic effect of insulin, which could account for low triglycerides and high HDL cholesterol levels, and consequently explain the higher protection from coronary heart disease experienced by black males compared with whites and black females.

The prevention of coronary artery disease is based on the control of several factors associated with a disease or clinical condition and suspected to play a pathogenetic role, defined as 'risk factors'. Smoking is a powerful risk factor for coronary artery disease, with risk of events increasing in relation to the number of cigarettes smoked daily. Smoking cessation is associated within 3-4 years, with a significant reduction in cardiovascular risk. Hyperlipidaemia is a powerful predictor of coronary disease with a strong, independent, continuous and graded positive association between cholesterol levels and risk of coronary events. Several large studies have shown the benefit of cholesterol reduction, and there is clear evidence of the efficacy of statins in the reduction of events in primary and secondary prevention. Hypertension is a significant, strong and independent risk factor for coronary artery disease morbidity and mortality and the reduction of events and mortality by antihypertensive treatment is well documented. Obesity is associated with an increase in all-cause mortality and cardiovascular mortality, with a particularly high risk for subjects with central obesity. Central obesity is also part of the so-called 'metabolic X syndrome' including insulin resistance, which appears to be associated with a particularly high risk of coronary artery disease. Type 1 and type 2 diabetes mellitus are associated with an increased risk of cardiovascular disease, especially in women. Several studies have shown that good metabolic control and multifactorial risk factor reduction significantly lower the coronary risk in these patients. Recent evidence is accumulating that some clotting factors (fibrinogen, factor VII, von Willebrand factor) and fibrinolytic factors (t-PA and PAI-1) are associated with an increased risk of coronary artery disease. The European Concerted Action on Thrombosis (ECAT) showed that the levels of fibrinogen, von Willebrand factor antigen, and t-PA antigen are independent predictors of subsequent coronary syndromes in patients with angina pectoris, and that low fibrinogen is associated with a low risk of events despite high cholesterol levels. Post-menopausal status is associated with increased risk of coronary artery disease, particularly when menopause is premature (before the age of 45) or abrupt (surgical). There is strong, thought not yet completely definite evidence that post-menopausal hormone replacement therapy may significantly reduce the risk of events and improve survival. Hyperhomocysteinaemia is an emerging risk factor independently associated with an increased risk of coronary artery disease, cerebral vascular disease, and peripheral vascular disease. The administration of vitamin B6, B12 or folate seems to be useful and is currently under further evaluation. Recently, attention has been focused on the correlation between coronary artery disease and genetic factors, such as ACE gene polymorphism or the gene polymorphism for the IIIa-moiety of the platelet fibrinogen receptor IIb-IIIa. In primary prevention, control of the major risk factors mainly in patients with clustered factors will substantially reduce the risk of ischaemic events. Secondary prevention of CHD is based on: aggressive behavioural advice, blood pressure reduction in hypertensives, good metabolic control of diabetes, and cholesterol reduction. Aspirin, beta-blockers, ACE inhibitors, and oral anticoagulants, may be useful in selected patients.
