Epidemiology of Type 2 Diabetes and HIV: A Comparative Analysis
This paper presents a comparative epidemiological analysis of two health conditions: type 2 diabetes (chronic) and HIV (infectious). Using established epidemiological frameworks, the paper examines predisposing, enabling, and reinforcing factors for each disease; their effects on daily living and behavioral functioning; natural and medicinal treatment options; health-promoting behaviors; and institutional influences on those behaviors. The paper further identifies appropriate behavioral learning theories — operant conditioning for diabetes and classical conditioning for HIV — and applies the Health Belief Model (HBM) as the primary health behavior theory for both conditions. The analysis concludes with a review of two peer-reviewed studies that apply HBM constructs to self-care and prevention in each disease population.

What makes this paper effective
- The parallel structure — addressing diabetes and HIV side by side within each thematic section — allows for clear, organized comparison throughout the paper.
- The paper grounds its analysis in named theoretical frameworks (PRECEDE model factors, operant conditioning, classical conditioning, and the Health Belief Model), demonstrating the ability to apply academic concepts to real health conditions.
- Citations are well-integrated, with direct quotations used selectively to support key definitions and claims rather than to substitute for original analysis.
Key academic technique demonstrated
The paper demonstrates systematic comparative analysis within a public health framework. Each section applies the same analytical lens to both conditions in turn, allowing the reader to track similarities and differences. The use of the PRECEDE framework's predisposing/enabling/reinforcing factor taxonomy to structure the opening section shows facility with epidemiological models beyond simple description.
Structure breakdown
The paper opens with a brief introduction identifying the two conditions, then moves through six substantive sections. Each section is divided into labeled subsections (a) Diabetes and (b) HIV. The paper progresses from etiology and social factors, through treatment and prevention, to theoretical frameworks, and closes with a review of two primary research studies — one per condition — that apply the Health Belief Model to intervention design.
Introduction
The two health conditions selected for this analysis are type 2 diabetes — the most common form of diabetes and a chronic condition — and human immunodeficiency virus (HIV), an infectious disease. The subsequent sections examine both conditions from multiple epidemiological perspectives, including predisposing factors, treatment options, behavioral theories, and health promotion strategies.
Predisposing, Enabling, and Reinforcing Factors
Predisposing factors have been defined by Merrill, Frankenfeld, Mink, and Freeborne (2015) as "antecedents to behavioral change that provide the rationale or motivation for the behavior" (p. 52). Some of the predisposing factors associated with type 2 diabetes include race, age, genetics, and beliefs and attitudes. Whereas race, age, and genetics are non-modifiable predisposing factors, beliefs and values are modifiable. With regard to the non-modifiable factors, the Centers for Disease Control and Prevention (CDC, 2022) indicates that type 2 diabetes risk is associated with belonging to certain racial categories (such as African American and Latino), being age 45 or older, and having a sibling or parent diagnosed with diabetes. When it comes to beliefs and attitudes, Friis and Sellers (2009) point out that certain cultural perspectives can increase people's susceptibility to diabetes. For instance, in the island of Nauru, being overweight is culturally associated with wealth and prosperity.
Enabling factors have been defined by Merrill et al. (2015) as "antecedents to behavior or environmental change that allow a motivation or environmental policy to be realized" (p. 52). Enabling factors can play a prominent role in the spread of disease. One key enabling factor in the case of diabetes is the absence of health education classes or programs to sensitize people about diet and other preventive measures — a gap that tends to have a negative impact on self-care behaviors.
According to Merrill et al. (2015), reinforcing factors include "factors following a behavior that provide the continuing reward or incentive for the persistence or repetition of the behavior" (p. 52). In the context of diabetes, the focus is largely on positive reinforcing factors — those that support prevention efforts and promote healthy outcomes among diagnosed individuals. Family support is one key reinforcing factor, and it can take various forms: providing emotional and mental support to diagnosed family members, and ensuring that meals recommended by healthcare professionals are available and accessible.
When it comes to HIV, some of the predisposing factors associated with the disease include attitudes and values, knowledge of health risks, and self-confidence. Beliefs and attitudes can influence whether a person chooses to engage in risky sexual behavior — shaped by life experiences such as early exposure to sex and familial perspectives on intimacy. An individual's knowledge of health risks associated with unprotected sex — beyond the risk of unwanted pregnancy — can also influence their behavior. Self-confidence plays a role as well; for example, whether an individual feels capable of declining a partner's request for unprotected sex.
Enabling factors can also play a crucial role in the spread of HIV or in frustrating efforts to control it. One key enabling factor is the inaccessibility of healthcare resources, particularly for those living in low-income areas. Critical services — such as HIV testing and treatment — may be financially out of reach for lower-income individuals. Another enabling factor is the failure to adequately address prostitution in certain jurisdictions, which can increase exposure to HIV among those who engage with sex workers who may be carriers of the virus.
Reinforcing factors associated with HIV include familial support, peer support, and community support. Family support can be instrumental in helping those diagnosed with HIV cope with the disease. As Friis and Sellers (2009) note, "family support can improve the confidence of HIV patients and it can lead to a longer life if it encourages the HIV patient to take their antiretroviral therapy (ARV) medicine" (p. 107). Peer support involves constructive engagement between persons living with HIV, allowing them to share experiences and encourage one another. According to Friis and Sellers (2009), peer support has been associated with improved wellbeing among those diagnosed with HIV. Both family and peer support are positive reinforcing factors.
Effects on Daily Living and Behavioral Functioning
Beyond physical health, diabetes has a notable impact on day-to-day life. Most people with diabetes must dedicate significant time to managing the disease, which reduces time available for other daily activities. They may also need to avoid certain types of food, sometimes requiring special meals to be prepared while those around them eat differently. There are also financial implications to consider, particularly regarding the cost of diabetes management medications — a burden that falls disproportionately on those in lower income brackets, adding to their overall cost of living.
Various studies have also indicated that blood sugar fluctuations can result in mood disturbances. As Coreil (2010) notes, "among diabetics, higher blood glucose, or hyperglycemia, has historically been associated with anger or sadness, while blood sugar dips, or hypoglycemia, has been associated with nervousness" (p. 79).
Friis and Sellers (2009) point out that persons living with HIV are more prone to a wide range of opportunistic infections. This means that people living with HIV must take extra preventive measures to maintain their immunity, which can carry cost implications and create significant inconvenience. Furthermore, although the situation has improved over recent decades, negative and irrational attitudes about HIV persist in many communities. HIV stigma can result in discriminatory practices at the workplace or in social settings, exposing persons living with HIV to depression, anxiety, and stress. As the CDC (2021) notes, "HIV stigma and discrimination affect the emotional well-being and mental health of people living with HIV... people living with HIV often internalize the stigma they experience and begin to develop a negative self-image."
