as an epidemiologist you are going to investigate the effect of lead exposure in a Baltimore neighborhood and the incidence of lead poisining and related difficulties in early childhood. You start with a cohort of 400 babies born in 2015. At baseline, none of them have any symptoms of lead poisining, but after taking envirnomental samples from their homes you find that 250 have lead paint exposure and 150 of them do not You follow them for ten years and keep track of incident cases of lead poisining based on blood samples. In 2025 you end your study and report the following: 100 of the children previously exposed to lead paint in 2015 have lead poisining and 25 of the children that were not exposed in 2015 have lead poisining. Calculate the cumulative incidence for the exposed group and the unexposed group. Calculate the relative risk between lead paint exposure and lead poisining.

Health Epidemiology

Health is an essential factor for all human beings. For all humans, health is a critical factor. An individual's ability to meet life's challenges and retain his or her capacity for optimal functioning is reflected in his or her condition of health. This needs the physical, mental, and biological parts of one's constitution to maintain a degree of functioning that has a favorable influence and support for one another.

As an epidemiologist you are going to investigate the effect of lead exposure in a Baltimore neighborhood and the incidence of lead poisoning and related learning difficulties in early childhood. You start your study with a cohort of 400 babies born in 2015. At baseline none of them have any symptoms of lead poisoning, but after taking environmental samples from their homes you find that 250 of them have lead paint exposure and 150 of them do not. You follow them for 10 years and keep track of incident cases of lead poisoning based on blood samples. In 2025 you end your study and report the following: 100 of the children previously exposed to lead paint in 2015 have lead poisoning and 25 of the children that were not exposed in 2015 have lead poisoning. Calculate the cumulative incidence for the exposed and unexposed group. Calculate the relative risk between lead paint exposure and lead poisoning.
An epidemiologist recruits 250 people for a cohort study. Of these potential study subjects, 11 are prevalent cases. The remaining study subjects are followed for 5 years, during which time 21 individuals develop the disease being studied.What is the prevalence of disease at the start of the study Assume all of the cases are still around at the end of the study. What is the prevalence now and What is the incidence proportion over the period of observation?
What patterns do you detect? Often in disease outbreak investigations we want to see a pattern for a particular problem. Think back to the 'white board' approach from a previous question and consider the types of information about individuals that may help you look for patterns. Select from the list below attributes that may help you You can chosse all or some I choose Time of disease onset and occuption but there is more I guess Occupation Hair color Gender Weight Age Time of disease onset

You conduct a case-control study in Portland pediatric clinics to evaluate the relationship between the exposure of exclusive breastfeeding for at least the first 6 months of life, and the outcome of no ear infections during the first year of life. The exposure is “exclusive breastfeeding” (as opposed to mixed feeding or formula feeding. The outcome of interest is “no ear infections during the first year of life” (as opposed to having at least one ear infection). Your study produces an OR of 0.3, relating exposure and outcome. Assuming that the 95% Confidence Interval indicates your result is statistically significant, the interpretation for the OR in your study is: A. The odds of exclusive breastfeeding among children with no ear infections during the first year of life is 0.3 times that of those with at least one ear infection during the first year of life. B.The odds of no ear infections during the first year of life among exclusively breastfed children is 0.3 times the odds…
An epidemiological study involved 674 workers of a vinyl chloride (a plastic manufacturing chemical) manufacturing plant. The study aimed to determine an association between exposure to vinyl chloride and liver cancer. Out of 200 workers who routinely worked in vinyl chloride production area, 15 developed liver cancer. Another group of workers consisting of individuals with smoking histories similar to the plant workers, and who were unlikely to have encountered vinyl chloride, had 24 develop liver cancers and 450 who did not develop liver cancer. a. Given the above information, fill in the 2x2 table below: Exposed: Plant workers Not Exposed: Control group TOTAL b. Calculate the relative risk Developed Liver Cancer Did not Develop Liver Cancer TOTAL 674

Swaziland is a small country relative to many other nations and the age distribution has more young people than old people. Thus, the epidemiologists who collected and analyzed the data want to know how these rates compare to other countries. Before making any comparisons, the epidemiologists first perform age adjustment. Why is it important to make age adjustment before comparing the data?
According to the World Health Organization WHO, malaria is a life threatening disease caused by parasites that are transmitted to people through the bites from the infected female Anopheles mosquitoes. It is a very preventable and curable disease. There are five parasite species that cause malaria in humans.Early detection of this killer disease is important for effective management of the disease and for strong surveillance.There are three conventional methods of diagnosis of malaria which include:1. Malaria Rapid Diagnostic Test (Malaria RDT)2. Malaria Microscopy (Blood Slide For Malaria Parasites – BS for MPs)3. Nucleic Acid Amplification Test (NAAT)For each of the above tests: a). State the principle of the test. B). Mention the specimen required and how it is collected, c). List the advantages and disadvantages of each particular test, finally d). Compare and contrast these tests in a table form.
