Consider the following example:Over the last weekend, six people went to the Alcan City Hospital emergency room with similar symptoms. The laboratory results for the six patients were indicative of an infection due to Escherichia coli (E. coli). Patient interviews revealed they had all eaten a meal at Sam’s Sandwich Food Truck during the Alcan City Fair within 48 hours of going tothe hospital. Further inquiries by the Alcan City public health officials identified that the source of the E. coli contamination was the lettuce that Sam’s had purchased from M&L Produce (a produce supplier located in Tempe, Arizona). Epidemiologists from the Arizona State Health Department determined that the lettuce that M&L supplied Sam’s was from a farm located in Xion, California (the key supplier for M&L Produce).Aside from the six patients who sought treatment, epidemiologists tracked down and conducted interviews with 400 of the fair attendees to identify any potential cases who did not seek treatment and compare data with those who attended but did not become ill. Interview questions pertained to descriptive aspects of the outbreak (person, place, and time). Analysis of data collected on foods eaten allowed the epidemiologists to narrow it down and identify sandwiches served by Sam’sSandwich Food Truck at the fair on Saturday as the source of infection. Alcan City public health officials were quick to visit the food truck to inquire into their food management and handling. The food truck owner was cooperative and helpful in providing licensing, permits, operations, and sales information.Descriptive epidemiologic studies are often conducted as precursors to analytic studies. Epidemiologic concepts are used to gather data to better understand and evaluate health trends in populations. Data, such as characteristics of the persons affected, place where an incident occurred, and time of occurrence, are collected and analyzed to look for patterns in an effort to identify emerging health problems. It was in just this way that the HIV/AIDS epidemic was first identified.In this Discussion, you will apply the epidemiologic concepts of time, place, and person to a specific population health problem. You will also consider methods for obtaining data to study an issue.ResourcesBe sure to review the Learning Resources before completing this activity.

It occurs when the body becomes resistant to insulin or does not produce enough insulin to maintain normal blood sugar levels. Using theepidemiologic model, this disease can be described based onperson, place, and time:·Person: Type 2 diabetes mostly affectsadults aged 45 and older, but in recent years, younger individuals, including teenagers, have also been diagnosed due to rising obesity rates. Individuals with risk factors such asobesity, poor diet, lack of physical activity, genetic predisposition, and underlying health conditions like hypertensionare more likely to develop this disease. Socioeconomic factors also play a role, as low-income populations may haveless access to healthcare, healthy food, and opportunities for physical activity.·Place: Type 2 diabetes is prevalent worldwide, but the highest rates are found in countries withhigh obesity rates and sedentary lifestyles. It is common in urban areas where fast food consumption is high and physical activity is low. In contrast, rural populations with limited healthcare access also experience high diabetes rates due to lack of awareness and medical support. Studies show that regions withlimited grocery stores and more processed food optionscontribute to higher diabetes risks.·Time: The incidence of Type 2 diabetes hassteadily increased over the past few decades, mainly due to changing lifestyles, increased processed food consumption, and sedentary behaviors. It is also achronic disease, meaning once diagnosed, individuals must manage it for life. Certain times of the· year, such as the holiday season, may lead to an increase in blood sugar levels due to excessive eating and reduced activity.·Sampling Methods for Primary Data Collection· To effectively study and describe Type 2 diabetes in a specific population, differentsampling methodscan be used:·Stratified Sampling– This method divides the population into subgroups based on characteristics such asage, BMI, ethnicity, and lifestyle. Researchers can then collect data from each subgroup to ensure a representative sample. This method helps compare risk factors across different groups.·Convenience Sampling– This method collects data frompatients visiting hospitals, clinics, or community health events. It is quick and cost-effective but may not fully represent the general population, as it focuses on individuals who actively seek healthcare.·Secondary Data Sources·Centers for Disease Control and Prevention (CDC) Reports– The CDC provides national and state-level statistics on diabetes, includingincidence rates, demographic trends, and risk factors. This data helps researchers analyze long-term trends and develop prevention strategies.·Electronic Health Records (EHRs)– Medical records from hospitals and clinics provide valuable data onpatient history, blood sugar levels, medication use, and disease progression. This data helps track diabetes patterns and evaluate treatment effectiveness.Case Identification and Definition·Primary data collectionhelps identify undiagnosed cases and providesdirect insights into risk factors, lifestyle choices, and disease management. It allows researchers to examine new cases and track individual health behaviors.·Secondary dataoffers a broaderunderstanding of population-wide trends, helping define case criteria and monitor disease progression over time. It is useful for comparing diabetes rates across different regions and demographic groups.··ReplyPreviousNextimage1.jpegWK2Discu.Epidermology.docxDescriptive Epidemiology: Data Sources and Data CollectionDescriptive epidemiology deals with describing disease patterns using three major categories: person, place, or time (Friis & Sellers, 2021).
