Weight-Related Health Risks
There are several adverse effects on health caused by obesity and excessive weight.
Weight and Hypertension
The age-adjusted prevalence of hypertension (raised blood pressure) in overweight U.S. adults is 22.1 percent for men with body mass index >25 and < 27; 27.0 percent for men with body mass index > 27 and < 30; 27.7 percent for women with body mass index > 25 and < 27; and 32.7 percent for women with body mass index > 27 and < 30.
In comparison, the prevalence of hypertension in adults who are not overweight (body mass index <25) is 14.9 percent for men and 15.2 percent for women.
The prevalence in adults who are obese (body mass index > 30) is 41.9 percent for men and 37.8 percent for women.17.
Note: Hypertension is defined as mean systolic blood pressure > 140 mm Hg, mean diastolic > 90 mm Hg, or currently taking antihypertensive medication.
Blood Pressure/Obesity Study
In the Intersalt Study, the relationship between body mass index (body mass index) and blood pressure was studied in over 10,000 men and women, aged 20-59 years of age. Body mass index was significantly associated with systolic and diastolic blood pressure, independent of age, alcohol intake, smoking habit, and sodium and potassium excretion.
In the Framingham Offspring Study, 78% of cases of hypertension in men and 64% in women were attributable to obesity.
Cholesterol and Weight
The age-adjusted prevalence of high blood cholesterol (> 240 mg/dL) in overweight U.S. adults is 19.1 percent for men with body mass index > 25 and < 27; 21.6 percent for men with body mass index > 27 and < 30; 30.5 percent for women with body mass index > 25 and < 27; and 29.6 percent for women body mass index > 27 and < 30.
In comparison, the prevalence of high cholesterol in adults who are not overweight (body mass index <25) is 13.0 percent for men and 13.4 percent for women. The prevalence for adults who are obese (body mass index > 30) is 22.0 percent for men and 27.0 percent for women.
Cancer and Weight
A recent study found that people whose body mass index was 40 or more had death rates from cancer that were 52 percent higher for men and 62 percent higher for women than rates for normal-weight men and women.
In both men and women, higher body mass index is associated with higher death rates from cancers of the esophagus, colon and rectum, liver, gallbladder, pancreas, and kidney. The same trend applies to cancers of the stomach and prostate in men and cancers of the breast, uterus, cervix, and ovaries in women.
Almost half of post-menopausal women diagnosed with breast cancer have a body mass index > 29.
