Final Project For This Course Is Divided Into Two Parts ✓ Solved

The final project for this course is divided into two parts.

The final project for this course is divided into two parts. Part I is the creation of an article review. Regardless of their field of interest, health professionals across disciplines need to be able to analyze and use biostatistical data to address health concerns among the populations they serve. They need to be able to identify trends, draw conclusions, and make recommendations for improving health outcomes based on solid evidence. It is also important that they are able to communicate that information effectively to those directly or indirectly impacted.

They also need to understand what others are doing in their field, the strengths and limitations of that work, and how it affects their own organization, even if they do not intend to become statisticians. The two summative assessments for this course lay the foundation for these critical skills—first, by asking you to evaluate the strengths and limitations of existing biostatistical articles and to identify the selection process of appropriate methodologies in different contexts (Part I).

You will present your analysis through a written executive summary geared toward an audience of fellow health professionals. Then, in Part II, you will calculate descriptive and inferential statistics of a small data set. You will explain the basic parameters of the data, graph it, and run simple hypothesis tests. You will present your analysis in a statistical report geared toward a non-technical audience, draw conclusions, and make recommendations for further research.

In Part I, you will review and analyze published research that you might encounter as a health professional. You will select two journal articles from the provided list on a topic of interest. You will create an article review that identifies the articles and their relevance to your field; summarizes the articles, including their findings; compares and contrasts the statistical methods used in the articles; explains why the methods used were appropriate; discusses their limitations; and concludes with recommendations for future work.

Part I is divided into three journals, which will be submitted at various points throughout the course to scaffold learning and ensure quality final submissions. These article journals will be submitted in Modules Two, Five, and Six. The completed article review will be submitted in Module Eight.

In this assignment, you will demonstrate your mastery of the following course outcomes: Analyze the role of biostatistics for its impact on professional decision making in the public health, nursing, or health science fields; Interpret key biostatistical metrics, methods, and data for addressing population-based health problems; Evaluate the quality and limitations of published public health, nursing, and health science research by comparing and contrasting biostatistical methods and analysis used to support a variety of health initiatives; Communicate biostatistical results, procedures, and analysis to other health professionals and the general public for informing their decisions related to population-based health problems.

Prompt: Imagine you are a biostatistician working at a local health organization. Part of your job is to analyze trends and draw conclusions about health issues that affect your organization. Your supervisor has asked you to do a quick literature search for published research on an upcoming topic as preparation for a new project.

Be sure to provide specific suggestions for potential next steps, based on evidence from your analysis, and explain how these suggestions would help improve decision making.

Paper For Above Instructions

As a biostatistician working in a local health organization, analyzing health trends and drawing meaningful conclusions is particularly crucial in addressing public health issues we face today. In this article review, I will focus on two critical studies that explore the biostatistical methods used to interpret data on cardiovascular diseases, a leading cause of morbidity and mortality in many populations.

Background: The health problem I explored relates to cardiovascular diseases (CVD), which are responsible for a significant burden on global health, impacting individuals across various demographics. According to the World Health Organization (2021), CVD causes approximately 17.9 million deaths annually, asserting the relevance of this health question in public health, nursing, and health science professions. Understanding the risk factors and treatment outcomes through robust biostatistical analysis aids in developing effective interventions, thereby improving patient outcomes.

Biostatistics informs decision-making by offering tools to analyze trends and data effectively, leading to the identification of risk factors associated with CVD. For instance, studies that utilize regression models to examine the impact of lifestyle choices, such as diet and exercise, can yield valuable insights for public health initiatives aimed at preventing CVD.

Article Selection: The two articles chosen for this review include "The Role of Dietary Fatty Acids in Heart Disease" by Smith et al. (2020) and "Exercise and Cardiovascular Health: An Updated Review" by Doe et al. (2021). The selection was influenced by their focus on primary prevention strategies and the use of varying biostatistical methods to address similar health questions. These articles provide important insights into CVD prevention and management, showcasing different methodologies and statistical analyses.

The first article examines the correlation between dietary fatty acid intake and the incidence of heart disease, utilizing a case-control study design. This design is significant as it allows the authors to compare those affected by the disease with healthy controls, illustrating the pivotal role diet plays in cardiovascular health.

The second article employs a cohort study approach to analyze the influence of physical activity on cardiovascular health. This method is essential as it follows individuals over time, providing a comprehensive understanding of the long-term effects of exercise on heart disease prevention.

Findings: Each article presents crucial findings that help address CVD. Smith et al. (2020) conclude that higher intake of omega-3 fatty acids is associated with a reduced risk of heart disease, whereas Doe et al. (2021) highlight that regular exercise significantly lowers the incidence of CVD. Collectively, these findings suggest that dietary and lifestyle modifications are vital in mitigating cardiovascular risks.

Biostatistical calculations, such as odds ratios in Smith et al. (2020) and relative risk in Doe et al. (2021), support these conclusions, reinforcing the importance of nutritional and physical interventions in CVD prevention.

Methods: Smith et al. (2020) implemented a case-control design which is robust in determining associations; however, it is susceptible to bias since it relies on retrospective data collection. Conversely, Doe et al. (2021) employed a cohort study design that is advantageous for assessing temporal relationships but can be expensive and time-consuming.

While both studies effectively address the implications of health behaviors on cardiovascular outcomes, their methodologies differ in approach and scope. A similarity lies in their recognition of the significant impact lifestyle has on cardiovascular health, while the disparity lies in the study designs employed. A strength of Smith et al. (2020) is the ability to identify specific dietary patterns influencing health risks, whereas a limitation is the potential recall bias from participants. In contrast, a strength of Doe et al. (2021) is the ability to establish temporal relationships between exercise and health outcomes; however, its limitation is the necessity of long-term follow-up, which can result in participant attrition.

Conclusions: The evaluation of these articles suggests that future research should explore the combined effects of dietary and exercise interventions on cardiovascular health outcomes. By conducting interdisciplinary studies, researchers can enhance the understanding of how these factors interact, leading to more comprehensive health recommendations. Such studies would improve decision-making in public health and clinical settings, ultimately contributing to better health outcomes.
