HLT 362V Module 3 Exercise 31 Question Paper

HLT362V

What are the two groups whose results are reflected by the t ratios in Tables 2 and 3?

Which t ratio in Table 2 represents the greatest relative or standardized difference between the pretest and 3 months outcomes? Is this t ratio statistically significant? Provide a rationale for your answer.

Which t ratio listed in Table 3 represents the smallest relative difference between the pretest and 3 months? Is this t ratio statistically significant? What does this result mean?

What are the assumptions for conducting a t-test for dependent groups in a study? Which of these assumptions do you think were met by this study?

Compare the 3 months and 6 months t ratios for the variable Exercise from Table 3. What is your conclusion about the long-term effect of the health-promotion intervention on Exercise in this study?

What is the smallest, significant t ratio listed in Table 2? Provide a rationale for your answer.

Why are the larger t ratios more likely to be statistically significant?

Did the health-promotion program have a statistically significant effect on Systolic blood pressure (BP) in this study? Provide a rationale for your answer.

Examine the means and standard deviations for Systolic BP at pretest, 3 months (completion of the treatment), and 6 months. What do these results indicate? Are these results clinically important? Provide a rationale for your answer.

Is this study design strong or weak? Provide a rationale for your answer.

Would you, as a health care provider, implement this intervention at your facility based on the Total Risk Score results? Provide a rationale for your answer.

HLT 362V Module 4 ANOVA Excel Worksheet

SYSTOLIC BLOOD PRESSURE IN DIFFERENT AGE GROUPS

The following table contains a random sample of 40 women partitioned into three groups:

Group 1: ages below 20

Group 2: ages 20 through 40

Group 3: ages over 40

The values in the table are the systolic blood pressure levels

The hypothesis test:

H0:u1=u2=u3

H1: at least one of the treatment means is different

Use the Excel Analysis ToolPak to create an Anova – Single Factor table. Is there sufficient evidence to support the claim that women in the different age categories have different mean blood pressure levels? Give reasons for your decision.

SYSTOLIC BLOOD PRESSURE IN DIFFERENT AGE GROUPS

Introduction

Blood pressure is a measure of the force that blood exerts against your arteries. It can be measured with a blood pressure cuff (also called an ambulatory sphygmomanometer) or via auscultation, which involves listening to your pulse while you take your blood pressure.

The American Heart Association offers these guidelines for blood pressure measurement in adults 18 and older:

The American Heart Association offers these guidelines for blood pressure measurement in adults 18 and older:

• Systolic blood pressure is the top number and should be less than 140 mm Hg.

• Diastolic blood pressure is the bottom number and should be less than 90 mm Hg.

The average systolic blood pressure for adults is 120 to 139 mm Hg, according to the AHA’s own research on this topic—and it’s important to note that there are no official standards for how much you should weigh in order to have healthy levels of both systolic and diastolic readings (see “Why Are Our Blood Pressure Numbers So Different?”).

What about people over the age of 80?

If you’re over 80 and have high blood pressure, the American Heart Association recommends that you be on medication. But it’s important to note that your risk of heart disease increases with age, so don’t be too quick to jump into treatment. As an example: A study published in a 2001 issue of Archives of Internal Medicine found that older men who took anti-cholesterol drugs had twice as many heart attacks than those who didn’t take them; however, men 80 years old or older weren’t included in this study (and thus weren’t counted). So if you’re past 80 and have high blood pressure but aren’t taking medication already—or if your doctor thinks it might help—talk about it with him or her before making any decisions about treatment options.

What about children and teens?

You might be wondering, “What about children and teens?” The same guidelines apply to both boys and girls.

The normal blood pressure range for most children is between 90/60 and 100/70 mm Hg, while it’s between 120/80 and 140/90 mm Hg in adults. If your child has a higher or lower systolic number than these values (or if you’re not sure where he falls), talk to his healthcare provider about his specific situation.

Always consult a healthcare professional to determine your target blood pressure.

The best way to determine your target blood pressure is by consulting a healthcare professional. Your target BP depends on the person’s age, health and family history.

Always consult a healthcare professional before taking any medication or making any changes in diet or exercise routine that have potential implications for your heart health.

Conclusion

You should always consult a healthcare professional to determine your target blood pressure. And remember that it’s important to take your blood pressure regularly, even if it’s not high. This will help you stay on top of any health issues and prevent them from worsening into potentially life-threatening conditions down the road.
