Biological Science Theories And Determinants In Public Healt

Biological Science Theories and Determinants in Public Health Interventions

In this assignment, your task is to focus solely on biological determinants. While not nearly as common as social determinants, biological determinants can have a major impact on an individual's quality of life. You will pair a biological determinant with a selected biological theory to demonstrate several real-world public health actions. This is divided into two parts.

Part 1: Choose one biological science theory from the following options: Evolution, Cell, or Genetics. Select a biological determinant of health that you have not previously discussed in the Week 3 Global Determinants forum. Also, choose a social determinant of health that is different from those previously shared. Compare and contrast the relationship between the chosen social determinant and the biological determinant, and analyze how these interrelate with the selected biological science theory. Support your evaluation with scholarly and government research. Additionally, hypothesize how communicable diseases such as malaria, polio, or COVID-19 could affect your chosen biological determinant.

Part 2: Write an evaluation addressing the following:

• Explain the social implications of utilizing biological science theories in public health interventions. Discuss the advantages and disadvantages, citing scholarly or government research.
• Assess the relationship between biological science theories and biological determinants of health, supported by scholarly research.
• Describe how biological science theories at national and international levels address biological determinants of health, providing supporting scholarly sources.
• Compare and contrast a real-world public health intervention targeting a biological determinant with one targeting a social determinant.
• Evaluate the outcomes and overall impact of these interventions.
• Discuss why public health interventions sometimes overlook biological determinants and theories compared to social determinants, considering social and political factors. Explain how these interventions vary between biological and social perspectives.

Paper For Above instruction

Public health strategies have historically concentrated more on social determinants of health; however, biological determinants are equally critical in understanding and improving population health. These determinants, including genetic predispositions, cellular functioning, or biological processes, influence an individual's susceptibility to diseases, response to treatment, and overall health outcomes. Integrating biological science theories such as evolution provides a deep understanding of how biological mechanisms evolve and adapt, informing targeted interventions.

Part 1: Biological and Social Determinants Interrelation through Evolutionary Theory

For this analysis, the selected biological theory is evolution, a process explaining how genetic variations occur and are selected over generations. A pertinent biological determinant of health is genetic predisposition to specific diseases, such as sickle cell anemia. The social determinant chosen is socioeconomic status (SES), which affects access to healthcare, nutrition, and living conditions. These two determinants—genetics and SES—interact significantly; for instance, individuals with genetic predispositions might experience worsened health outcomes if socioeconomic disadvantages limit their access to preventive care and treatment, thereby accelerating disease progression.

The evolutionary perspective helps explain how genetic traits like sickle cell anemia persist in populations exposed to malaria. The heterozygous advantage conferred by sickle cell trait offers resistance to malaria, demonstrating an evolutionary adaptation. This biological adaptation is influenced by social factors; impoverished regions with high malaria prevalence often have populations with higher frequencies of this trait due to selective pressures.

In contemplating communicable diseases such as COVID-19, genetic factors might influence individual susceptibility or severity, while social determinants impact exposure risk and health behavior. For example, crowded living conditions (a social determinant) facilitate virus spread, which interacts with biological susceptibility—highlighting the complex interplay between biology and social factors in public health.

Part 2: Evaluating Public Health Interventions and Theoretical Implications

Applying biological science theories in public health interventions carries significant social implications. An advantage is the precision in targeting specific biological vulnerabilities, leading to tailored treatments and prevention strategies. For instance, genetic screening programs for hereditary conditions enable early detection and management. However, drawbacks include potential stigmatization and privacy concerns when genetic data is misused or misunderstood (Kohane et al., 2018).

Biological science theories elucidate how biological determinants influence health outcomes, reinforcing the importance of integrating genetics, cell biology, and evolution into public health approaches. At national and international levels, agencies like the World Health Organization (WHO) utilize biological understandings to shape vaccination policies and disease eradication programs, exemplified by the global effort to eradicate smallpox through vaccination based on understanding viral evolution and immunology (Fenner et al., 1988).

A notable example contrasting biological and social interventions is the vaccination program for preventable diseases versus health education campaigns addressing behavioral factors such as smoking cessation. Vaccination directly targets the biological agent or host susceptibility, often leading to immediate reductions in disease incidence. In contrast, social interventions aim to modify behaviors and socio-economic conditions, which may require longer-term efforts with variable outcomes.

The effectiveness of interventions depends on addressing both biological and social factors; however, public health initiatives tend to emphasize social determinants, possibly due to political, cultural, and ethical considerations. Biological interventions, while scientifically robust, may encounter resistance linked to ethical debates about genetic modification or privacy issues (Parson et al., 2019).

In conclusion, the integration of biological science theories enhances the effectiveness of public health initiatives by providing targeted, evidence-based strategies. Nevertheless, overlooking biological determinants could lead to gaps in addressing health disparities and disease control, emphasizing the need for comprehensive approaches that consider both biological and social factors.
