Assignment 2: Dropbox Assignment Current Epidemiological Studies Criti

For your dropbox assignment, using the South University Online Library or the Internet, research and select three current epidemiological studies regarding risk factors that are associated with any health problem. You can also use the following websites to search for studies as they are often used as the major sources of information for health research and often report on the most current health problems affecting the United States and global populations: U.S. National Library of Medicine National Institutes of Health Centers for Disease Control and Prevention World Health Organization. Based on your research, create a report in a 3- to 4-page Microsoft Word document addressing the following questions: What were the criteria that you used to select these papers? (For example, only English language, peer-reviewed articles, only a specific age group, only United States studies, etc.) What were the types of risk factors studied in your chosen articles? (For example, environmental, socio-economic, behavioral, etc.) Which study design was used for this study? Why do you think the researchers chose this specific study design? Provide examples from your research. What are the proximate or underlying determinants of risk factors that are associated with any health problem for each study? Answer the questions posted below in the Template for

Assessment of Causality for Reviewing Epidemiological Studies, for each study. You should number each study, list the title, and state each question in the format it appears in the template. Support your responses with examples. Cite any sources in APA format. Submission Details: Name your document SU_HCM2001_W3_A2_LastName_FirstInitial.doc. Submit your document to the W3 Assignment 2 Dropbox.

Paper For Above instruction

The selection of epidemiological studies for analyzing risk factors associated with health problems requires a systematic and criteria-based approach to ensure relevance, quality, and reliability of data. For this assignment, three recent studies were chosen from reputable sources, including peer-reviewed articles and authoritative health organizations' repositories, such as the CDC, WHO, and PubMed. The criteria guiding this selection included language (English only), publication within the last five years to ensure current relevance, focus on human populations, and specific geographic or demographic parameters—most studies were based in the United States to capture national health issues.

The types of risk factors examined in these studies encompassed various dimensions such as behavioral factors (smoking, diet, physical activity), environmental exposures (pollutants, occupational hazards), and

socio-economic conditions (income level, education). For instance, one study investigated the impact of smoking and air pollution on respiratory diseases, while another focused on dietary patterns and obesity, and a third examined socio-economic disparities affecting mental health outcomes.

Regarding study design, the studies employed different methodologies, primarily cohort and cross-sectional designs. Cohort studies were utilized to observe the influence of risk factors over time, providing insights into causality and temporal relationships. Cross-sectional studies offered snapshot assessments of current risk factor prevalence and associations. The choice of these designs aligns with the research objectives: cohort studies naturally fit investigations of causality, while cross-sectional designs are suitable for prevalence and correlation assessments.

The researchers' selection of study design appears deliberate, balancing the need for causal inference and feasibility. For example, a longitudinal cohort study on cardiovascular risk factors enables tracking changes and establishing temporal sequences, crucial for causality. Conversely, cross-sectional designs are more practical for initial screening and hypothesis generation but limited in causal conclusions.

The underlying determinants of the studied risk factors further elucidate their influence on health outcomes. For example, socio-economic status determines access to healthy foods and healthcare, impacting obesity and chronic disease risk. Environmental exposures are often rooted in industrial policies and residential zoning, reflecting broader societal determinants. Behavioral factors like smoking are influenced by cultural norms, stress levels, and education, all contributing to the health problem's etiology.
