The seeds of premature coronary heart disease are often sown in childhood and it is the developing arteries of children which are the most susceptible. Paediatricians and all who work with them have the earliest and most promising opportunities for prevention. Coronary protection can be added to the potential advantages of breast feeding and to ensure appropriate fatty acid balance throughout weaning. It is reasonable to accept the strong consensus of opinion on diet reflected in the reports of the eighteen national committees. They are: to reduce total fat intake to 30-35% of the energy, to restrict consumption of saturated fat, cholesterol, sugar, and salt, to increase unrefined carbohydrate and polyunsaturated fat, and to maintain a P/S balance of 1.0-1.5:1. Food is the fundamental coronary risk factor, but others may add insult to injury. Smoking, hypertension, obesity, lack of exercise, and stress, each of which is related to behaviour, may start in childhood. Smoking doubles the overall risk CHD and increases it ten times in males under 45 years old. Good habits, including food preferences and eating patterns learned early, are those most likely to be continued. School meals require and should match revised nutritional education. The co-operation of the food industry is essential and can be anticipated, but it requires a clear lead by paediatricians. The nutritional advice should come from the medical profession. Every contact with children and their parents provides an opportunity for enquiry and giving advice.

The results of total hip replacement in 39 patients 30 years old or younger were evaluated including 67 Charnley low-friction arthroplasties and one McKee total hip arthroplasty. The average age was 25.9 years with an average follow-up of 39 months, the longest being 8 years, 3 months. The diagnoses included rheumatoid arthritis, ankylosing spondylitis, CDH, Still's disease, and a miscellaneous group. Over-all function did not improve as greatly as in the 9 to 10 year series, but this was due to a higher proportion of patients with severely disabling rheumatoid polyarthritis, hemiplegia, severe obesity, or cardiovascular disease. Wear did not seem to be any greater in this younger age group as compared to previous studies in older patients.

With improvements in life expectancy and as more and more people have access to modern medicine, non-communicable diseases are emerging as a health problem in both urban and rural communities in Myanmar. Of all non-communicable diseases, cardiovascular diseases (CVD) are known to be the major health problem. Since many studies that have been conducted in both developed and developing countries have shown a difference between rural and urban communities with regard to cardiovascular diseases, our study had the objective of finding out the prevalence of ischemic heart disease, hypertensive heart disease and rheumatic heart disease in a rural and urban community. The risk of obesity and smoking in the occurrence of CVD was also studied. A cross-sectional survey was conducted in three urban townships of Yangon City (Sanchaung, Latha and Pabedan) and one rural township of Hmawbi. The results showed that CVD were a health problem in both the urban and rural communities. Coronary heart disease was seen to be more prevalent in the urban townships than in the rural Hmawbi Township, but hypertension (HT) and rheumatic heart diseases (RHD) were more prevalent in the rural township of Hmawbi. Obesity which has been blamed as the major risk factor for CHD and HT in the developed countries was not found to be a risk factor in the study townships, but smoking was.

A risk factor is a characteristic which is associated with a greater than average probability of developing coronary disease. Raised serum cholesterol and hypertension are two such factors. Intervention studies conducted to confirm the risk factor hypothesis have shown that reduction of serum cholesterol and essential hypertension may be associated with a small decreased CHD incidence, however there were almost as many deaths due to coronary disease in the intervention groups as in the control groups. These findings suggest that our approach to risk factor intervention may be a misguided attempt which needs modification. It is possible that the major risk factors develop in an attempt of our body to adapt to environmental factors such as increased intake of salt, saturated fat and cholesterol, physical inactivity, increased intake of calories and obesity and stress. Smoking may be the result of social changes. Since the body has to modify its metabolic mechanism depending upon the factor to which it adapts, development of hyperlipidemia and hypertension may be protective mechanisms of the body which it has developed while fighting against environmental factors. Reduction of major risk factors by drug therapy may mean that we are trying to prevent the body, fighting environmental factors. Thus our approach to control of the major risk factors should be to treat the causative environmental factors or alter the lifestyle.(ABSTRACT TRUNCATED AT 250 WORDS)

The relationship between erythrocyte sodium-lithium countertransport (Na-Li CT) and body fat distribution is analyzed in a sample (n = 101) of normotensive and untreated hypertensive men participating in an epidemiological study of coronary heart disease risk factors. Na-Li CT is significantly and positively associated with both subscapular skinfold and waist to hip ratio, but not with triceps skinfold. The univariate correlation between Na-Li CT and blood pressure is diminished when adjusted for body mass index and waist to hip ratio. These findings support the existence of an association between Na-Li CT and central body fat distribution and suggest that the metabolic abnormalities associated with centrally distributed body fat could explain, at least in part, the association between Na-Li CT and blood pressure. The maximal velocity of the sodium-lithium countertransport (Na-Li CT) in erythrocytes has been reported to be directly associated with blood pressure and hypertension in numerous reports from both clinical and epidemiological studies. In most of these studies, indices of weight and/or adiposity (body mass index, in particular) have been shown to be among the most important correlates of Na-Li CT. Adiposity is an important determinant of blood pressure, and there is evidence suggesting that the patterning of the fat cells in the body is linked to a number of metabolic disturbances that could lead to hypertension and an increase in other CHD risk factors. The present report analyses the relationship between Na-Li CT and body fat distribution in a sample of normotensive and untreated hypertensive men participating in an epidemiological study.

The association of hostility to behaviorally induced (i.e. smoking behavior, alcohol consumption and physical activity) and somatic coronary risk indicators (i.e. LDL- and HDL-cholesterol, systolic and diastolic blood pressure and obesity) was studied in a randomly selected representative sample of healthy adolescents and young adults (n = 1609). The question was whether the association, previously found between hostility and CHD incidence could be confirmed between hostility and CHD risk level in healthy young subjects. Results indicate that hostility is unrelated to somatic coronary risk factors, while an association with behaviorally induced risk factors was found. This association was, however, mediated by gender: current and heavy smoking, and physical inactivity were reported more commonly by hostile women, while frequent drinking by hostile men. These findings were replicated in a 3-year follow-up.

Risk of cardiovascular events was determined over 24 years of surveillance in relation to general adiposity reflected by relative weight and by regional obesity estimated by skinfolds and waist girth per inch of height. Upper quintile values of relative weight, subscapular skinfolds and waist girth were each associated with increased risks of cardiovascular disease in both sexes. Risk of total cardiovascular events increased with the degree of regional, central or abdominal obesity. Mortality from cardiovascular disease was also increased. Increased relative weight and central obesity were both associated with increased risk factors including cholesterol, blood pressure, glucose and uric acid. Changes in weight were mirrored by changes in risk factors with linear trends over a 15 lb range of weight fluctuations. Subscapular skinfold and the ratio of subscapular-to-triceps skinfold, measures of central obesity, were in either sex also associated with an increased probability of coronary attacks in particular. The subscapular skinfold contributed to CHD risk independent of body mass index (BMI). Multivariate analyses taking all the risk factors into account indicate an independent effect of abdominal obesity on stroke, cardiac failure and cardiovascular and all-cause mortality in men. In women, only the subscapular-to-triceps skinfold ratio independently contributes to CHD, cardiovascular and all cause mortality. Regional obesity appears to be an independent contributor to cardiovascular disease at a given level of general adiposity, its effect only partially mediated through promotion of other known risk factors. These data suggest that cardiovascular disease is as closely linked to abdominal as to general adiposity.

Contrary to opinions generally accepted in the past, CHD is very common in both African-American men and women, with incidence rates approaching those of US Caucasians. Higher prevalence of hypertension, diabetes, cigarette smoking, and obesity all contribute to the high level of CHD in African-Americans. Additional research is needed about the interrelations and management of various risk factors for CHD in African-Americans outside of the sudden death of African-Americans outside of the hospital is urgent, and special attention should be given to accessibility and use of health services by minority populations.

Heart disease is the leading cause of death for Asian-Americans and Pacific-Islanders, Hispanic-Americans, and Native Americans. Generally, heart disease death rates are lower in these population groups than in Caucasians, with the notable exception of Native Americans under the age of 35. Of particular interest are data for southwestern US Native Americans and Mexican-Americans, which indicate low CHD prevalence rates despite high rates of obesity, diabetes mellitus, increasing hypertension, and low socioeconomic status. Much more research is needed to explain these and other observations. Intervention in those risk factors already identified is necessary, particularly in prevention of obesity and diabetes.

Development of strategies to prevent CHD in blacks is impeded by the virtual absence of clinical trials demonstrating the feasibility and effectiveness of interventions in blacks. The wholesale generalization that interventions effective (or ineffective) in whites are similarly effective in blacks may risk the employment of worthless or even dangerous interventions in blacks. Using available epidemiologic data, a number of risk factors may be more important in blacks than whites by virtue of higher prevalence, increased relative risk, or both. These may include hypertension, lipoprotein (a), smoking, diabetes, and obesity. Thus, health agencies might emphasize these risk factors when developing preventive programs targeted at black populations. Prevention programs may best seek to prevent the onset of risk factors found highly prevalent in black communities, rather than the costly and side-effect-prone interventions to treat risk factors once established. Thus, there is a role for community-based as well as a high-risk approaches. The community-based approaches should seek to work with organizations such as churches, which traditionally play strong roles in the black community. Physicians treating black patients should be aware of the potentially different roles played by risk factors, and treat aggressively those individuals identified to be at high risk. Risk factor management should be emphasized, rather than reduced, in patients with already established CHD. CHD has been clearly shown to be preventable; both blacks and whites should benefit from specific interventions aimed toward this worthy goal.
