Obstructive sleep apnea syndrome is the most common organic sleep disorder resulting in excessive daytime somnolence. It is almost as common as asthma. According to recent epidemiologic studies, the prevalence of obstructive sleep apnea syndrome is probably about 2% in women and somewhere around 4% in adult men in general. Many elderly people have the syndrome, and it is very common among patients who are morbidly obese, acromegalic, asthmatic; patients with arterial hypertension and heart disease, those with adult onset diabetes; and among patients with craniofacial abnormalities. In those groups, more than 30% or 40% of patients may have obstructive sleep apnea syndrome. Even more patients may have sleep apnea without daytime symptoms or partial upper airway obstruction during sleep. Among children, symptoms such as snoring and apneic episodes are relatively rare, but a high proportion of children with these symptoms have hypoxic respiratory events. Some recent methodologic issues and use of questionnaires are discussed.

The widely propagated morbidity and mortality risks of obesity appear somewhat exaggerated, except for morbid obesity (BMI > 40 kg/m2) and for high risk obese subgroups concerning diabetes mellitus, hypertension, metabolic syndrome and obstructive sleep apnea syndrome. Non-medical reasons represent a major component of the social pressure that is presently experienced by obese persons in our society. Weight reduction represents the primary therapeutic approach in overweight patients with type 2 diabetes, hypertension, metabolic syndrome and obstructive sleep apnea, and it may be recommended in high-risk individuals for primary prevention of these diseases. Massive obesity is associated with excess mortality, especially in younger, physically inactive men with upper-body-segment obesity. It is widely assumed that weight reduction will lead to a reduction of excess mortality in these individuals; so far, however, there is no proof for this assumption. Non-medicamentous conservative therapeutic approaches to weight reduction have the advantage of safety, even though their long-term efficacy is generally disappointing. There are no randomized, controlled trials to prove a reduction of morbidity or mortality risks and of therapeutic safety for pharmacological, invasive or surgical methods to treat obesity.

Several epidemiological studies have suggested that sleep-disordered breathing is a risk factor for cardiovascular disease, particularly hypertension, stroke and IHD. The relative risk for IHD among obstructive SAS(OSAS) patients is 1.2 to 6.9 higher compared with the general population. The prevalence of SAS with an apnea-hypopnea index(AHI) of 10 and over was 35 to 40% in IHD, while 23.8% of SAS patients had IHD. These evidence suggests that IHD is an important prognostic factor in SAS patients. Characteristic pathophysiological conditions such as sleep apnea-induced hypoxemia and sympathetic activation may play an important role in the genesis of nocturnal angina pectoris. Most patients with OSAS are obese, and the complication of non-insulin dependent diabetes mellitus is quite a few. Insulin resistance is also attracting great attention as a cause of the cardiovascular complication of SAS.

Obesity has become an increasingly important medical problem in children and adolescents. In national surveys from the 1960s to the 1990s, the prevalence of overweight in children grew from 5% to 11%. Outcomes related to childhood obesity include hypertension, type 2 diabetes mellitus, dyslipidemia, left ventricular hypertrophy, nonalcoholic steatohepatitis, obstructive sleep apnea, orthopedic problems, and psychosocial problems. Once considered rare, primary hypertension in children has become increasingly common in association with obesity and other risk factors, including a family history of hypertension and an ethnic predisposition to hypertensive disease. Obese children are at approximately a 3-fold higher risk for hypertension than nonobese children. In addition, the risk of hypertension in children increases across the entire range of body mass index (BMI) values and is not defined by a simple threshold effect. As in adults, a combination of factors including overactivity of the sympathetic nervous system (SNS), insulin resistance, and abnormalities in vascular structure and function may contribute to obesity-related hypertension in children. The benefits of weight loss for blood pressure reduction in children have been demonstrated in both observational and interventional studies. Obesity in childhood should be considered a chronic medical condition that is likely to require long-term management. Ultimately, prevention of obesity and its complications, including hypertension, is the goal.

The prevalence of obesity is increasing worldwide. In the United States, in 1999, 27% of adults had a body mass index >30 kg/m(2), almost double the prevalence of 20 years earlier. The estimated mortality from obesity-related diseases in the United States is approximately 300,000 annually and growing. In the future, mortality related to obesity is expected to exceed that of smoking. Numerous diseases are caused or made worse by obesity. These include type 2 diabetes; hypertension; dyslipidemia; ischemic heart disease; stroke; obstructive sleep apnea; asthma; nonalcoholic steatohepatitis; gastroesophageal reflux disease; degenerative joint disease of the back, hips, knees, and feet; infertility and polycystic ovary syndrome; various malignancies; and depression. Type 2 diabetes is perhaps the most visible obesity-related problem. Present in at least 14 million Americans, it leads to serious complications and premature death. It is largely caused by obesity, and is generally cured by weight loss. The quality of life of the obese is markedly reduced, and the costs to health care systems are great. Preventive programs have yet to affect the rising prevalence. An effective solution is needed.

Rapidly accumulating evidence shows that sleep apnea is a major factor influencing personal health and public safety. Diagnosis and treatment of this syndrome may well result in significant preventive medicine outcomes. The prevalence of sleep apnea is so high that evaluation and treatment must become the province of the primary care physician. Accurate, appropriate history, physical assessment and clinical management are the mainstays of care, with the judicial application of technology. A history of snoring, particularly when it is intermittent, interrupted by snorts, and accompanied by restless sleep or daytime sleepiness suggests the need for further evaluation. When co-morbid conditions such as hypertension, cardiovascular disease or type 2 diabetes are present, formal evaluation and consideration of treatment are needed. If initial evaluation reveals severe obstructive sleep apnea with observed apneas, together with excessive daytime sleepiness, clinical management with empirical application of continuous positive airway pressure (CPAP) may suffice in experienced hands.

The science of sleep is in early stages of development, and the biochemical consequences of obstructive sleep apnea (OSA) are slowly being identified. Only recently have investigators begun to identify the commonalities and interaction between OSA and insulin resistance, the underlying pathology of type 2 diabetes. Obesity and increasing age play important parts in the natural history of both conditions, which frequently coexist. The purpose of this article is, first, to examine the extent and strength of studies that have investigated the association between OSA and increased insulin resistance or type 2 diabetes and, second, to propose a model that explains the association and cyclical interaction between OSA, obesity, and insulin resistance.

Twelve to twenty-five percent of human population suffer from sleep disorders and sleep-related breathing disorders have a frequency of 5-10%. The association between sleep-related breathing disorders and several diseases, mainly cardiovascular and dysmetabolic, is well known. The aim of this study was to assess the prevalence of this association in a group of 620 patients, aged between 18 and 78 years and referred to the Laboratory of Respiratory Pathophysiology of the Umberto I Hospital of Rome. All patients had a clinical history of a sleep-related breathing disorder and answered a specific questionnaire. One-hundred-and-thirty-seven patients (120 males and 17 females, mean age 64 years), whose questionnaire was suggestive of a sleep-related breathing disorder, underwent clinical assessment including blood tests, lung function tests, blood-gas analysis, ECG and nocturnal polysomnography, either as in- or as out-patients. The main associated pathologies were: arterial hypertension (54.7%), chronic obstructive pulmonary disease (17.9%), obesity (63.1%), dyslipidemia (41%), type 2 diabetes mellitus (6.3%), gastroesophageal reflux (27.3%) and cardiac arrhythmias (4.2%); 95 patients with obstructive sleep apnea syndrome were treated, on the basis of the polysomnography outcomes and according to the Italian Association of Sleep Medicine Guidelines, either with preventive strategies for risk factor reduction, or with medical (positive pressure ventilation, oxygen, assessment of the best drug medication) and/or ear, nose end throat surgical therapies. In most patients, the improvement in the sleep-related breathing disorder was associated with an improvement in their systemic pathology, in particular cardiovascular disease, suggesting the need of a deeper consideration and comprehension of nocturnal apneas.

The prevalence in obesity has increased dramatically over the past 30 years, more than double in the United States alone. Obesity is associated with an increased risk for type 2 diabetes mellitus, dyslipidemia, hypertension, biliary disease, obstructive sleep apnea, and certain types of cancer. The pathophysiology of obesity is complex, involving behavioral, environmental, and genetic factors. Current treatment options include behavior modification and lifestyle changes which incorporate weight-reducing diets and physical activity, FDA approved long-term anti-obesity pharmacological agents sibutramine and orlistat, non-FDA approved over-the-counter (OTC) supplements and nutriceuticals, and, when appropriate, bariatric surgery. Without adequate prevention and treatment of obesity, government agencies have suggested that the direct and indirect costs associated with obesity may overwhelm the healthcare system. This brief review explores the current data available on treatments for the obese patient including the relative merits of different types of macronutrient composition (e.g., low carbohydrate vs. high carbohydrate diets) of weight-reducing diets, the value of resistance/ strength training in physical activity programs designed for the obese patient, the safety and efficacy associated with OTC supplements and nutriceuticals for weight reduction (e.g., Ephedra, conjugated linoleic acid (CLA), Garcinia cambogia/ hydroxycitric acid (HCA), chromium, pyruvate), the safety and efficacy of FDA-approved long-term obesity treatments sibutramine and orlistat, and bariatric surgery.

The metabolic syndrome, an emerging public health problem, represents a constellation of cardiovascular risk factors. It has been suggested that the presence of obstructive sleep apnea (OSA) may increase the risk of developing some of the features of the metabolic syndrome, including hypertension, insulin resistance, and type 2 diabetes. In this article, we discuss the parallels between the metabolic syndrome and obstructive sleep apnea and describe possible OSA-related factors that may contribute to the metabolic syndrome, specifically the roles of obesity, hypertension, dyslipidemia, sex hormones, inflammation, vascular dysfunction, leptin, insulin resistance, and sleep deprivation.
