Hyperglycemia and hyperinsulinemia are central features of the metabolic syndrome and type 2 diabetes mellitus, which contribute to the pathogenesis of coronary heart disease (CHD). Recent data indicate that increased dietary glycemic load (GL) due to replacing fats with carbohydrates or increasing intake of rapidly absorbed carbohydrates (ie, high glycemic index) can create a self-perpetuating insulin resistance state and predicts greater CHD risk. In this paper, we discuss the historic development of the GI and GL concepts and summarize metabolic experiments and epidemiologic observations relating to clinical utilities of these measures. On balance, increased consumption of low-GI foods leads to improvements in glycemia and dyslipidemia in metabolic studies, and a low-GL diet has been associated with lower risk of type 2 diabetes and CHD in prospective cohort studies. We conclude that decreasing dietary GL by reducing the intake of high-glycemic beverages and replacing refined grain products and potatoes with minimally processed plant-based foods such as whole grains, fruits, and vegetables may reduce CHD incidence in sedentary individuals and populations with a high prevalence of overweight. Because of advances in food-processing technologies and changes in ingredients in our food supply, the composition and physiologic effects of foods are likely to change over time. Future efforts should continue to quantify and monitor the metabolic impacts of different foods, and such information should be routinely incorporated into long-term prospective studies to allow for the assessment of the interactive effects of diets and other metabolic determinants on chronic disease risk.

We propose an explanation for variation in disease outcomes based on patient adaptation to the conditions of chronic disease. We develop a model of patient adaptation using the example of Type 2 diabetes mellitus and assumptions about the process entailed in transforming self-care behaviors of compliance with treatment, compliance with glucose monitoring, and patient's knowledge seeking behavior into health outcomes of glycemic control and patient satisfaction. Using data from 609 adults with diagnosed Type 2 diabetes we develop an efficiency (fitness) frontier in order to identify best practice (maximally adapted) patients and forms (archetypes) of patient inefficiency. Outcomes of frontier patients are partitioned by categories of returns to scale. Outcomes for off-frontier patients are associated with disease severity and patient archetype. The model implicates strategies for improved health outcomes based on fitness and self-care behaviors.

As the leading cause of chronic disease mortality in developed nations, cardiovascular disease is a widely prevalent condition that is integral to evaluation of aging populations. Chronic diseases such as coronary heart disease, hypertension and type 2 diabetes have been associated with adulthood body composition-namely excess body fat, altered lipid levels and elevated blood pressures. The Fels Longitudinal Study conducted at the Lifespan Health Research Center at Wright State University's School of Medicine has examined these same health status indicators-body composition, blood pressure, lipids, maturation, and hormones-during early life and their relationships to developing risk factors for these chronic diseases in adulthood. Research conducted during the past 10 years has shown health status indicators to track over time from childhood to adulthood. Furthermore, chronic disease risk factors attained during childhood, adolescence or early adulthood may represent an early warning system for future risk of developing cardiovascular disease.

The worldwide epidemic of obesity is being mirrored in worldwide epidemics of metabolic syndrome and of type 2 diabetes. The theme of the 2002 Future Forum conference is that these conditions are a certainty, given that the changing worldwide environment requires less physical activity for daily living and assures an abundant, energy-dense food supply at all times. This paper focuses on the roles of physical activity and weight reduction in reducing the risk for development of type 2 diabetes and the metabolic syndrome. The mechanisms by which obesity and detraining lead to insulin resistance and type 2 diabetes are discussed and, conversely, the mechanisms by which insulin resistance might be reversed by physical activity are addressed. Finally, the evidence from recent randomised clinical trials is reviewed. The Finnish Diabetes Prevention Study and the Diabetes Prevention Program in the USA both demonstrate that lifestyle change can significantly reduce the risk of development of type 2 diabetes in individuals with impaired glucose tolerance. Furthermore, these studies demonstrate that modest weight change and achievable physical activity goals can translate into significant risk reduction. Societies cannot afford to ignore the evidence of health benefit associated with physical activity and healthy weight in favour of medicating when morbidities develop. For a successful public health approach to chronic disease prevention, we cannot rely completely on pharmaceuticals, but must implement environmental changes to encourage healthy lifestyles.

The glycemic index (GI) has proven to be a useful nutritional concept, providing new insights into the relationship between foods and chronic disease. Observational studies suggest that diets with a high glycemic load (GI x carbohydrate content) are independently associated with increased risk of type 2 diabetes and cardiovascular disease. Postprandial hyperglycemia plays a direct pathogenic role in the disease process. Lower glucose and insulin levels are associated with improved risk profile, including high-density lipoprotein cholesterol, glycosylated proteins, oxidative status, hemostatic variables, and endothelial function. Limited evidence suggests that a low-GI diet may also protect against obesity, colon cancer, and breast cancer. Diets with a high glycemic load may affect health differently in insulin-resistant and insulin-sensitive individuals. Improvements in postprandial hyperglycemia can be brought about by manipulating either the type (i.e., GI) or amount of dietary carbohydrate, or both; at present, the GI appears to be more effective.

The United Kingdom Prospective Diabetes Study (UKPDS) is one of the longest and largest clinical trials ever conducted. It explored the effects of intensive blood glucose and blood pressure control on the development of complications in patients with type 2 diabetes. Patients took part in this trial for up to 20 years and the drop-out rate was extremely low. The aim of this discussion paper is to explore patients' motivations for joining the UKPDS and for remaining in the trial, and to examine the implications of findings for good practice before, during, and after clinical trials. A qualitative, exploratory study was undertaken, involving former UKPDS patients (n = 10) at Northampton General Hospital, England. In-depth, semi-structured interviews were undertaken and the data analysed using grounded theory approaches. The results showed that patients were motivated to join the UKPDS because they believed this would give them the best clinical care and reduce the threat of the disease. However, all of the patients identified unanticipated benefits of trial participation, to which they attributed their strong commitment to the UKPDS. These included the reassurance provided by regular clinical examinations, the personal nature of clinical care, and the welcome discipline imposed by UKPDS professionals. Transition back to primary care at trial closure could be a lonely experience, despite follow-up being seen as competent. Practitioners involved in recruiting patients for clinical trials should be aware that participants may be motivated by the desire for better clinical care, irrespective of randomisation consequences. Those taking back the clinical care of trial participants with chronic disease may wish to consider a 're-entry' interview, to minimise trial bereavement.

The emergence of type 2 diabetes mellitus in the American Indian/Alaska Native pediatric population presents a new challenge for pediatricians and other health care professionals. This chronic disease requires preventive efforts, early diagnosis, and collaborative care of the patient and family within the context of a medical home.

Aging is associated with a number of physiologic and functional declines that can contribute to increased disability, frailty, and falls. Contributing factors are the loss of muscle mass and strength as age increases, a phenomenon called sarcopenia. Sarcopenia can result or be exacerbated by certain chronic conditions, and can also increase the burden of chronic disease. Current research has demonstrated that strength-training exercises have the ability to combat weakness and frailty and their debilitating consequences. Done regularly (e.g., 2 to 3 days per week), these exercises build muscle strength and muscle mass and preserve bone density, independence, and vitality with age. In addition, strength training also has the ability to reduce the risk of osteoporosis and the signs and symptoms of numerous chronic diseases such as heart disease, arthritis, and type 2 diabetes, while also improving sleep and reducing depression. This paper reviews the current research on strength training and older adults, evaluating exercise protocols in a variety of populations. It is clear that a variety of strength-training prescriptions from highly controlled laboratory-based to minimally supervised home-based programs have the ability to elicit meaningful health benefits in older adults. The key challenges as this field of exercise science moves forward are to best identify the most appropriate strength-training recommendations for older adults and to greatly increase the access to safe and effective programs in a variety of settings.

The Talking Circle, a culturally appropriate, 12-week educational intervention, was employed on two Northern Plains American Indian reservations to provide information on type 2 diabetes. In a phenomenological study, funded as a minority supplement to the Talking Circle intervention, the authors asked 8 American Indian participants of the Talking Circle to describe their experience of being an American Indian Talking Circle participant. Seven common themes describe the phenomenon of participating in a Talking Circle diabetic intervention. The Talking Circle technique was effective in providing information on type 2 diabetes through culturally appropriate community sharing. Type 2 diabetes is viewed by both outsiders and those involved as a chronic disease of the utmost concern in American Indian communities.

Family context is thought to influence chronic disease management but few studies have longitudinally examined these relationships. Research on families and chronic illness has focused almost exclusively on European American families. In this prospective study we tested a multidimensional model of family influence on disease management in type 2 diabetes in a bi-ethnic sample of European Americans and Latinos. Specifically, we tested how baseline family characteristics (structure, world view, and emotion management) predicted change in disease management over one year in 104 European American and 57 Latino patients with type 2 diabetes. We found that emotion management predicted change in disease management in both groups of patients as hypothesized, while family world view predicted change in both ethnic groups but in the predicted direction only for European Americans. Examining family context within ethnic groups is required to elucidate unique cultural patterns. Attending to culturally unique interpretations of constructs and measures is warranted. The import of family emotion management, specifically conflict resolution, in disease management deserves further study to support clinical intervention development. Examining multiple domains of family life and multidimensional health outcomes strengthens our capacity to develop theory about family contexts and individual health.
