摘要: The World Health Organization defines overweight and obesity as an abnormal or excessive fat accumulation that impairs health. However, there are no well established cut-offs to define based on body fat. NIH, WHO, the American Association of Clinical Endocrinologist, College Endocrinology excess total fat, specifically is 20–25% weight in men, 30–35% women. But not enough data supporting these predictors adverse outcomes. Furthermore, because direct difficult measure, more widely available easier perform anthropometric measurements used clinical practice. Body mass index most commonly accepted measure obesity. It a known conditional risk factor for development several cardiovascular factors, such diabetes mellitus type 2, metabolic syndrome, systemic hypertension, dyslipidemia, obstructive sleep apnea, etc. recently scientists have questioned its usefulness slightly increased (overweight mild range) has been related improved survival fewer events when compared subjects with normal index, phenomenon “obesity paradox”. Anthropometric measures take into consideration distribution, mainly truncal and/or abdominal obesity, waist circumference specially waist-to-hip ratio appear better predict than BMI alone, but this remains be proven. Interestingly, despite being gold standard very little regarding impact predictor all-cause mortality. following chapter will analyze different including lean their mortality focus mortality, leading cause death worldwide.
