of age. Also, let us assume that the average SBP for a 50-year-old woman is 125 mm Hg, with a standard deviation of 15 mm Hg, and that SBP is normally distributed. 5.71 What proportion of 50-year-old women is hyperten- sive, if hypertension is defined as SBP 2 140 mm Hg? From previous clinical trials, it is estimated that for every 10 lbs. of weight loss there is, on average, a corresponding reduction in mean SBP of 3 mm Hg. 5.72 Suppose an average woman did not gain any weight from age 18 to 50. What average SBP for 50-year-old women would be expected under these assumptions? 5.73 If the standard deviation of SBP under the assumption in Problem 5.72 remained the same (15 mm Hg), and the distribution of SBP remained normal, then what would be the expected proportion of hypertensive women under the assumption in Problem 5.72? 5.74 What percentage of hypertension at age 50 is attrib- utable to the weight gain from age 18 to 50?

Cardiovascular Disease Obesity is an important determinant of cardiovascular dis- ease because it directly affects several established cardio- vascular risk factors, including hypertension and diabetes. It is estimated that the average weight for an 18-year-old woman is 123 lbs. and increases to 142 lbs. at 50 years

Expert Solution
Step 1

Given Information:

The average weight of an 18-year-old woman is 123 lbs and increases to 142 lbs at 50 years of age.

Mean μ=125 mm Hg

Standard deviation σ=15 mm Hg

For every 10 lbs of weight loss, there is, on average, a corresponding reduction in mean SBP of 3 mm Hg.
