a reasearcher is interested in the cause of neonatal jaundice . To study this condition, he selects one hundred children who were diagnosed with neonatal jaundice. He also selects another one hundred children born during the same time period at the same hospital who did not have a diagnosis of neonatal jandnice. He then reviewed the obstetrical and delivery records of their mothera to determine if there were any prenatal or perinatal exposures to risk factors.

what study design was used in this study?

cross-sectional

prospective cohort

case-control

randomized controlled trial

Expert Solution

Answer is: Case Control.

Here two population, one with diagnosis for neonatal Jaundice and one without, has been chosen. Then the delivery records of their mother has been checked in order to find the prenatal or perinatal exposures to risk factors.

Hence here two cases (one positive and one counter) has been reviewed to find the reason.

So this is a case control study.

Why other options are incorrect:

Ø In cross sectional only one population has been checked. So here this is not the case

Ø In prospective cohort the similar individuals or cohorts should be studied. But here one with and one without the diagnosis has been studied.

Ø In randomized controlled trial, the population should be allocated randomly. But here separate population has been considered and then studied.

Create a Case Study "Controlling trachoma in Morocco" Health Condition: Trachoma is the second leading cause of blindness in the world, and the number one cause of preventable blindness. More than 84 million people in 55 countries have trachoma. Economic development and improved hygiene have eliminated the disease from North America and Europe. But it plagues millions in hot, dry regions where access to clean water, sanitation, and health care is limited. In 1992, a national survey found that just...

Pre-term birth is a common cause of neonatal mortality, especially in low-income and middle-income countries. A large randomized study was conducted across six countries with high rates of pre-term birth to investigate the effectiveness of taking daily low-dose aspirin for reducing the risk of giving birth before 37 weeks. The 5,780 women randomized to the treatment group received a daily 81 milligram aspirin tablet at the start of the third trimester, while the 5,764 women randomized to the control group...

Race White All others Black Neonatal Mortalities 12164 6564 5920 75.10% 12.600% 12.30% You are interested in determining if neonatal mortality is equally likely across races in the United States. You know that at the time of analysis, the United States was composed of 75.1% white individuals, 12.3% black individuals, and 12.6% of other races and you can presume that births match these proportions. If neonatal mortality is not equally likely across all races, then determine which categories differ from...

In a cognitive psychology experiment, the researcher is interested in whether encoding condition has a significant effect on memory for a list of words. She recruits 32 subjects to participate in the experiment. Each recruited subject is randomly assigned to either encoding condition A or encoding condition B. The researcher would like to leave the hypothesis non-directional without predicting which encoding condition would lead to better memory, and she sets the significance level at α = .05 for a two-tailed...

In a cognitive psychology experiment, the researcher is interested in whether encoding condition has an effect on memory for a list of words. She recruits 16 subjects to participate in the experiment. Each subject comes to the lab twice to be tested in two different encoding conditions and their memory performance scores are listed below. The researcher would like to leave the hypothesis non-directional without predicting which encoding condition would lead to better memory, and she sets the significance level...
