Overweight and obesity characterized by excess body fat resulting from a positive energy balance (i.e., an
energy intake greater than energy expenditure).
Persian physician Avicenna viewed obesity as a health hazard, devoting an entire chapter to it in his Canon of
Medicine
percentage of adults worldwide that are obese 20%
percentage of adults in the united states that are obese 40%
number of deaths BMI has accounted for worldwide 4.7 million deaths
What is rank is BMI as a risk factor 4th
highest prevalency of obesity black females
Lowest prevalence of obesity asian
most accurate way of assessing body fat Quetelets body mass index (BMI)
Underweight BMI <18.5 kg/m2
Normal BMI 18.5-24.9 kg/m2
Overweight BMI 25-29.9 kg/m2
Obesity BMI I 30.0-34.9 kg/m2
Obesity BMI II 35-39.9 kg/m2
Extreme obesity BMI >_40 kg/m2
Waist circumference positively correlated with abdominal fat content and provides a clinically
acceptable measurement for assessing a patient's abdominal fat content before
and during weight loss treatment
Waist circumference considered risky for men 102 cm (40 in.)
Waist circumference considered risky for women 88 cm (35 in.)
Waist-to-Hip Ratio predicts the patterning of visceral fat. Excess fat above the waist, so-called
androidal fat, increases risk for CHD more than does excess fat below the waist,
so-called gynoidal fat.
, metabolic syndrome the co-occurrence of obesity with diabetes or prediabetes, hypertension, and
dyslipidemia increasing the absolute risk for CHD & cardiovascular mortality
According to NHANES, what is the age-adjusted 34%
prevalence of metabolic syndrome among U.S. Adults
Set Point Theory hypothesizes that the body has an internal control mechanism, a set point,
located in the lateral hypothalamus of the brain, that regulates metabolism to
maintain a certain level of body fat.
Settling point theory proposed by obesity researcher James Hill of the University of Colorado to help
explain why overweight and obesity are more than problems of metabolism. His
idea is that weight loss and gain in most humans are more related to the patterns
of diet and physical activity that people settle into as habits based on the
interaction of their genetic dispositions, learning, and environmental cues to
behavior.
Harvard Alumni Study & Obesity Being physically active can reduce the risk of death even in the presence of
obesity. The 25% to 33% reduction in all-cause deaths among men who expended
at least 2000 kcal/week was still present regardless of smoking, high BMI, or gains
in body weight during the years of follow-up
Nurses health study & obesity Findings showed that higher levels of physical activity reduced, but did not
eliminate, the elevated risk of death associated with high BMI.
Womens health study & obesity - High BMI and physical inactivity were each related to elevated risk of CHD.
- the risk of CHD associated with high BMI was reduced but not eliminated by
physical activity.
Lipid research clinics morality study Men who were fit and fat had the same mortality risk as those who were fit and
not fat, but the risk ratios were about 75% higher in the unfit men, regardless of
fatness. Among U.S. men, low fitness and fatness each increased mortality risks by
about 40% to 50%. Thus, fitness eliminated the risks of obesity in Russian men, but
in American men, fitness and fatness were associated with mortality
independently of each other
Women's Ischemia Syndrome Evaluation Each 1-MET level of estimated fitness was associated with an 8% decrease in the
risk of major adverse cardiovascular events during follow-up independently of
CAD risk factors.
Aerobics Center longitudinal study & Obesity Lower mortality risk in higher fitness groups remained after adjustment for
smoking, baseline health, and either BMI, waist circumference, or percent body
fat. The association between waist circumference and mortality was eliminated
after adjustment for fitness
NHANES follow up study & Obesity A low level of physical activity reported in the follow-up survey was strongly
related to major weight gain.
