Cardiovascular Disease Obesity is an important determinant of cardiovascular disease because it directly affects several established cardiovascular risk factors, including hypertension and diabetes. It is estimated that the average weight for an 18-year-old woman is 122 lbs. and increases to 143 lbs. at 50 years of age. Also, let us assume that the average SBP for a 50-year-old woman is 124 mm Hg, with a standard deviation of 14 mm Hg, and that SBP is normally distributed. (Assume that SBP can be measured exactly and no continuity correction is necessary.) USE SALT (a) What proportion of 50-year-old women are hypertensive, If hypertension defined as SBP ≥ 140 mm Hg? (Round your answer to four decimal places.) (b) From previous clinical trials, it is estimated that for every 10 lbs. of weight loss there is, on average, a corresponding reduction mean SBP of 3 mm Hg. Suppose an average woman did not gain any weight from age 18 to 50. What average SBP (in mm Hg) for 50-year-old women would be expected under these assumptions? mm Hg (c) If the standard deviation of SBP under the assumption in part (b) remained the same (14 mm Hg), and the distribution SBP remained normal, then what would be the expected proportion f hypertensive women under the assumption in part (b)? (Round your answer to four decimal places.) (d) What percentage % hypertension at age 50 is attributable to the weight gain from age 18 to 50? (Round your answer to two decimal places.)
