Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Are blood pressure and weight correlated? What analytical test can be used?
A
Anova
B
T-test
C
Chi-square
D
Correlation
Explanation: 

Detailed explanation-1: -Body mass index (BMI) is positively associated with both systolic blood pressure (SBP) and diastolic blood pressure (DBP). Weight loss significantly reduces blood pressure (BP), 6-8 suggesting that BMI is not merely a marker of factors associated with high BP but is causally associated.

Detailed explanation-2: -According to the national guidelines and recent research, losing weight can lower both systolic and diastolic blood pressure–and potentially eliminate high blood pressure. For every 20 pounds you lose, you can drop systolic pressure 5-20 points.

Detailed explanation-3: -Determine the regression equation of blood pressure on age: The regression equation of blood pressure on age is y = 153.6 + 0.8x. This means that for every increase of 1 unit in age, the blood pressure increases by 153.6 units, but the effect of age on blood pressure is only slightly significant (p = 0.055).

Detailed explanation-4: -According to the INTERSALT study, incidence of high BP and its increase with age is associated with high sodium intake, low potassium intake, lack of exercise, obesity and high alcohol consumption.
