Lifestyle Modification Education for Obesity Management in Primary Care: A Capstone Proposal

Lifestyle Modification Education for Obesity Management in Primary Care: A Capstone Proposal

The obesity epidemic is a public health problem that disproportionately affects low-income and Hispanic communities, as well as urban communities, and is one of the most crisis-stricken in the United States. These rates are even higher in Miami-Dade County, FL, where more than 67% of adults are either overweight or obese, and need systematic, evidence-based intervention through the primary care channel/Centers for Disease Control and Prevention, 2023). The prevalence of adult obesity nationally has risen to 40.3% from August 2021 to August 2023, and for those who were already overweight, the prevalence of severe obesity was 9.4% over this period (Karam et al., 2025). These figures equate with elevated rates of Type 2 diabetes and cardiovascular disease, and hypertension – an economic burden for patients and the healthcare system. Nevertheless, few primary care offices have an obesity-focused education program that is consistent from one office to another, and patients are not knowledgeable enough or equipped to lower their body weight to a healthy level. This is a proposed Capstone project: To implement a structured lifestyle modification education program in PC clinics in Miami-Dade County, which will be administered to overweight and obese adults for 8-12 weeks.

PICOT Question

The clinical question guiding this project is: In overweight or obese adults attending primary care clinics in Miami-Dade County (P), how does structured lifestyle modification education (I), compared to no standardized education (C), affect body weight or BMI reduction (O) over 8–12 weeks (T)? The population consists of adults who are overweight (BMI ≥ 25) or obese and seek health care in primary care settings in counties with a majority Hispanic and Latino population, and often have challenges with access to nutritious food, health care literacy, and safe recreation areas (Williams et al., 2024). The intervention comprises one-on-one counseling provided by Advanced Practice Registered Nurses (APRNs) on nutrition, portion control, physical activity, behavioral self-monitoring, and goal setting. Comparisons are with the current standard of care—the absence of any structured obesity education, with patients only receiving general clinical advice. The target is to lose a clinically significant amount of weight or BMI (around 5% of body weight compared with baseline level). A properly structured behavioural programme, as evidenced, can actively produce measurable anthropometric changes in 8-12 weeks time (Krishnasamy et al., 2024).

Vulnerable Population and Setting

The target population includes overweight and obese adults in Miami-Dade County, home to nearly 2.5 million residents, the majority identifying as Hispanic or Latino. The intersecting social determinants of food insecurity, low household income, limited English language ability, and lack of affordable, nutritious food make this community vulnerable. Studies have found that racial and ethnic minorities and adults with low SES are at higher risk for obesity and less likely to access quality obesity treatment (Williams et al., 2024). Cultural dietary habits and community access to physical activity also contribute to weight gain and to the progression of chronic diseases. Primary care clinics are an ideal setting because they are the first point of contact between the patient and the healthcare system, allowing for early detection, frequent monitoring, and reinforcement of healthy behaviors during the intervention period.

Review of Evidence

There is significant peer-reviewed evidence for the effectiveness of structured lifestyle modification education programs in the primary care setting for weight and BMI reduction. Karam et al. (2025) conducted a review of obesity interventions that utilized primary care settings and identified behavioral therapies, such as motivational interviewing and lifestyle modification counseling, to be consistently associated with clinically significant weight loss, suggesting that APRNs and primary care providers are well-equipped to facilitate these therapies. Krishnasamy et al. (2024) assessed a nurse-led intervention in overweight and obese urban adults and found weight loss, BMI, waist circumference, and blood pressure levels to be lower at follow-up; participants' perception of the intervention's success was due to the structured educational material and the ongoing nursing care. A systematic review and meta-analysis by García-Rodríguez et al. (2024) showed that nurse-led interventions resulted in an average weight loss of 2.59 kg, with an average BMI reduction of 1.05 kg/m² and a waist circumference reduction of 2.52 cm compared to traditional care, demonstrating that nurse-led education interventions have a consistent and measurable impact on anthropometric changes across diverse patient populations. Williams et al. (2024) also found that culturally responsive, social determinants of health-focused programming is needed to achieve equity in minority-majority communities like Miami-Dade. Overall, this information demonstrates the viability and efficacy of the intervention selected for the population and intervention setting.

Proposed Intervention

The intervention will be an eight to twelve-week structured lifestyle modification education program provided in primary care clinics by APRNs and trained nurses. The screening of patients will be done during the routine visits according to the standard BMI evaluation, and patients will be enrolled when their BMI ≥ 25 kg/m². It will consist of at least four, 45-60 minute, individually scheduled sessions focusing on nutrition literacy, caloric balance, physical activity guidelines, portion control, and behavioral self-monitoring strategies every two weeks. To meet the linguistic need of Miami-Dade residents, all educational materials will be available in English and Spanish. For assessment of outcomes, anthropometric data such as weight, BMI and waist circumference will be collected at the start and end of the program. The program does not require any specific equipment other than the clinical equipment used in primary care and is designed to be integrated into clinical practice without a large financial investment. The implementation process takes 12 weeks; staff orientation (weeks 1-2), patient education (weeks 3-10) and outcome measurement and documentation (weeks 11-12).

Theoretical Framework

The project is based on Self-Care Deficit Nursing Theory (Orem, 1971) and Change Theory (Kurt Lewin, 1962). According to Orem's theory, nursing intervention must be implemented when patients don't know or have the ability to participate in needed self-care behaviors. There is a self care deficit in understanding what patients need to do in terms of diet, exercise and behavior modification for obesity management. The educational program proposed explicitly meets this need, and thus helps patients to learn how to manage their weight on their own for the long term. Isik and Fredland (2023) validated that Orem's theory is applicable to the development of self-care behaviors of patients through structured nursing education, which is very relevant to this intervention. Lewin's Change Theory is a model that helps to understand the process of change within behavioral change and how it can be made easier by unfreezing, changing and refreezing. In the unfreeze stage, patients will identify obesity as a risk factor that can be changed and express readiness for change through motivational discussion.Patients will voice readiness for change and recognize obesity as a modifiable risk in the unfreeze stage through motivational discussion. In the transition period, education will provide encouragement of new behaviors and reinforcement of healthier habits. Follow up visits and tools for self monitoring, embedded in the daily routine, continue to increase improvements in the refreezing stage. As such, the application of Lewin's theory in this primary care obesity education program was supported by the work of Amina et al. (2022) who showed that the theory is effective in guiding systematic improvements in healthcare and maintaining patient outcomes in the long-term. These frameworks work together to foster patient empowerment, evidence-based practice, and sustained patient behavior.

Conclusion

Obesity disproportionately burdens Miami-Dade County residents and contributes to preventable chronic disease, increased healthcare costs, and reduced quality of life. A proposed evidence-based, structured lifestyle modification education program will be investigated as a way to address the critical lack of standardized obesity counseling offered in primary care within Primary Care Settings, having been inspired by complementary nutrition theories and strong evidence. This Capstone project is intended to achieve measurable BMI and weight loss within this viable, culturally responsive, APRN-led intervention for vulnerable adults over an 8–12 week period. It represents the critical need for advanced practice nursing to make a major contribution that significantly reduces population-level health disparities through education, advocacy, and evidence-based practice in perhaps the most limited setting possible: the quiet realm of routine primary care.
