Question

A researcher is studying whether current excercise gudelines for reducing blood pressure are applicalbe to older person. This study design was a six month randomized controlled trial of combined aerobic and resistance training. Controls followed susual physical activity and diet advice. Participants ages 55-75 had unteated systolic BP of 130-159 or distolic 85 to 99. There were 51 exercisers and 53 controls who completed the trial. The overall mean +- sd was 63.6 +- 5.7. There were mean decreases in both SBP and DBP respectively among exercisers and among conrols (p<0.001 for all). There were no significant group difference is mean SBP change from baseline. The DBP reduction was greater amoung exercisers. Body composition improvement explained 8% of the SBP reduction (0+0.006) and 17% of the DBP reduction p<0.001) Which two pieces of data should be used to make a conclusion about this study? choose 2 answers. 1) Body composition means. 2) mean blood pressure. 3) Group BMI values. 4) P values for both groups.

Explanation / Answer

Result:

A researcher is studying whether current exercise guidelines for reducing blood pressure are applicable to older person. This study design was a six month randomized controlled trial of combined aerobic and resistance training. Controls followed usual physical activity and diet advice. Participants ages 55-75 had untreated systolic BP of 130-159 or diastolic 85 to 99. There were 51 exercisers and 53 controls who completed the trial. The overall mean +- sd was 63.6 +- 5.7. There were mean decreases in both SBP and DBP respectively among exercisers and among conrols (p<0.001 for all). There were no significant group difference is mean SBP change from baseline. The DBP reduction was greater amoung exercisers. Body composition improvement explained 8% of the SBP reduction (0+0.006) and 17% of the DBP reduction p<0.001) Which two pieces of data should be used to make a conclusion about this study? choose 2 answers.

1) Body composition means.

3) Group BMI values.

Answer: 4) P values for both groups.
