In the vertebral bodies, the end plates are preferentially involved, giving bands of dense bones adjacent to the end plates with a central band of lower normal bone density.

Reviewing the evidence within the framework of a life-course approach highlights the importance of the adult phase of life order parlodel 2,5 mg, it being both the period during which most chronic diseases are expressed generic parlodel 2,5 mg with visa, as well as a critical time for the preventive reduction of risk factors and for increasing effective treatment (93) cheap parlodel 2,5 mg fast delivery. The most firmly established associations between cardiovascular disease or diabetes and factors in the lifespan are the ones between those diseases and the major known ‘‘adult’’ risk factors, such as tobacco use, obesity, physical inactivity, cholesterol, high blood pressure and alcohol consumption (94). Most of the studies are from developed countries, but supporting evidence from developing countries is beginning to emerge, for example, from India (104). In developed countries, low socioeconomic status is associated with higher risk of cardiovascular disease and diabetes (105). As in the affluent industrialized countries, there appears to be an initial preponderance of cardiovascular disease among the higher socioeconomic groups, for example, as has been found in China (98). It is presumed that the disease will progressively shift to the more disadvantaged sectors of society (10). There is some evidence that this is already happening, especially among women in low-income groups, for example in Brazil (106) and South Africa (107), as well as in countries in economic transition such as Morocco (108). These include the role of high levels of homocysteine, the related factor of low folate, and the role of iron (109). From a social sciences perspective, Losier (110) has suggested that socioeconomic level is less important than a certain stability in the physical and social environment. In other words, an individual’s sense of understanding of his or her environ- ment, coupled with control over the course and setting of his or her own life appears to be the most important determinant of health. Marmot (111), among others, has demonstrated the impact of the wider environment and societal and individual stress on the development of chronic disease. Along with the societal and disease transitions, there has been a major demographic shift. Although older people are currently defined as those aged 60 years and above (112), this definition of older people has a very different meaning from the middle of the last century, when 60 years of age and above often exceeded the average life expectancy, especially in industrialized countries. It is worth remembering, however, that the majority of elderly people will, in fact, be living in the developing world. Most chronic diseases are present at this period of life --- the result of interactions between multiple disease processes as well as more general 39 losses in physiological functions (113, 114). Cardiovascular disease peaks at this period, as does type 2 diabetes and some cancers. The main burden of chronic diseases is observed at this stage of life and, therefore, needs to be addressed. Changing behaviours in older people In the 1970s, it was thought that risks were not significantly increased after certain late ages and that there would be no benefit in changing habits, such as dietary habits, after 80 years old (115) as there was no epidemiological evidence that changing habits would affect mortality or even health conditions among older people. There was also a feeling that people ‘‘earned’’ some unhealthy behaviours simply because of reaching ‘‘old age’’. Then there was a more active intervention phase, when older people were encouraged to change their diets in ways that were probably overly rigorous for the expected benefit. More recently, older people have been encouraged to eat a healthy diet --- as large and as varied as possible while maintaining their weight --- and particularly to continue exercise (113, 116). It seems that, as elderly patients have a higher cardiovascular risk, they are more likely to gain from risk factor modification (118). Although this age group has received relatively little attention as regards primary prevention, the acceleration in decline caused by external factors is generally believed to be reversible at any age (119). Interventions aimed at supporting the individual and promoting healthier environments will often lead to increased independence in older age. Risk of impaired glucose tolerance has been found to be highest in those who had low birth weight, but who subsequently became obese as adults (18). Further research is needed to define optimal growth in infancy in terms of prevention of chronic disease. Raised blood pressure, impaired glucose tolerance and dyslipidaemia also tend to be clustered in children and adolescents with unhealthy lifestyles and diets, such as those with excessive intakes of saturated fats, cholesterol and salt, and inadequate intake of fibre. In older children and adolescents, habitual alcohol and tobacco use also contribute to raised blood pressure and to the development of other risk factors in early adulthood. Such clustering represents an opportunity to address more than one risk at a time. The clustering of health-related behaviours is also a well described phenomenon (127). Maternal birth size is a significant predictor of a child’s birth size after controlling for gestational age, sex of the child, socioeconomic status, and maternal age, height and pre-pregnant weight (129). There are clear indications of intergenerational factors in obesity, such as parental obesity, maternal gestational diabetes and maternal birth weight. Low maternal birth weight is associated with higher blood pressure levels in the offspring, independent of the relation between the offspring’s own birth weight and blood pressure (7). Unhealthy lifestyles can also have a direct effect on the health of the next generation, for example, smoking during pregnancy (9, 130). Genes define opportunities for health and suscep- tibility to disease, while environmental factors determine which susceptible individuals will develop illness. In view of changing socio- economic conditions in developing countries, such added stress may result in exposure of underlying genetic predisposition to chronic diseases. The dynamics of the relationships are becoming better understood but there is still a long way to go in this area, and also in other aspects, such as 41 disease prevention and control. Studies on genetic variability to dietary response indicate that specific genotypes raise cholesterol levels more than others. The need for targeted diets for individuals and subgroups to prevent chronic diseases was acknowledged as being part of an overall approach to prevention at the population level.
