Summary Introduction

To determine: The trend of cigarette smoking among high school students in the time period between 1991-2015.

Introduction: Current smoking is defined as smoking cigarettes on at least one day in the 30 days preceding the survey. The U.S Center for Disease Control and Prevention (CDC) conducts biennial Youth Risk Behavior Surveys (YRBS) in which the high school students are asked to self-report their risky behaviors such as alcohol consumption and smoking. The results obtained were represented in the form of graphs.

b.

Summary Introduction

To determine: The high school students that are most likely found to be smokers.

Introduction: The high school students of three different races/ethnicity (white, black, and Hispanic) and gender (males and females) were involved in the study to observe the trend of current smoking between them. The results obtained were represented in the form of a graph.

A case-control study is conducted to estimate the association between sedentary lifestyle and stroke. Researchers enroll 100 patients who had a stroke in the past year and 400 patients who have never had a stroke. Researchers conclude that the prevalence of stroke in the past year in the population is 20%. This conclusion is: Correct Incorrect because prevalence cannot be estimated from a case-control study Incorrect because the prevalence is 25%
A case-control study was conducted to evaluate the relationship between physical activity and coronary heart disease (CHD) in men. A total of 406 men newly diagnosed with CHD were included together with 406 men of similar ages who did not have CHD. The risk of CHD (measured by the OR) was higher among men who were inactive or only moderately active (collectively called ‘inactive’) than among those who were physically active: (See attached image)  Odds ratio for inactive men compared to active men= (299 x 136)/(270 x 107)=1.41Suppose there is no misclassification in these data.What would the observed OR have been... 1. If 20% of all the inactive men had been misclassified as active?  2. If 10 % of inactive cases had been misclassified as active?
