In particular, the prevention of noncommunicable chronic diseases (NCDs), such as hypertension, diabetes, and cardiovascular diseases, is one of the priorities of PHC due to their high prevalence and significant impact on global morbidity and mortality (Starfield, 2011). Investing in PHC brings benefits ranging from reducing hospitalizations to improving patients’ quality of life. Chronic diseases pose a major challenge to health systems, especially in resource-limited countries such as Brazil. Managing these conditions requires a continuous, person-centered approach, including regular clinical follow-up, health education, and the promotion of healthy habits. In this context, PHC offers a favorable environment for the development of preventive actions and the Abstract Primary Health Care (PHC), as a major public policy, is the foundation of public health systems and plays a crucial role in health promotion, disease prevention, and the continuous and comprehensive care of the population. The prevention of noncommunicable chronic diseases (NCDs), such as hypertension, diabetes, and cardiovascular diseases, is one of the priorities of PHC due to their high prevalence and impact on global morbidity and mortality. This academic essay, based on an integrative literature review, analyzes the essential role of PHC in reducing hospitalizations, improving quality of life, and ensuring the sustainability of health systems. Emphasis is placed on health education, healthy lifestyle promotion, care coordination, and social determinants management, as well as the success of Brazil’s Family Health Strategy in addressing chronic conditions. The expansion and qualification of PHC are necessary for strengthening equitable, efficient, and person-centered health systems.

Moreover, PHC is strategically positioned to reduce health inequalities by facilitating access to basic services and ensuring care coordination, which is essential for effective prevention and management of NCDs. The expansion and qualification of PHC is a priority strategy to address the growing impact of chronic diseases, ensuring sustainability and efficiency in the health system (Paim et al., 2011). Methodology This academic essay was developed based on an integrative review of the scientific literature, addressing the importance of primary care in the prevention of chronic diseases. Articles published in national and international journals were selected, prioritizing recent studies with high academic impact, extracted from SciELO, PubMed, and Web of Science databases. The goal was to build a critical and updated analysis based on reliable scientific evidence. Development Primary health care is the preferred entry point to the health system, allowing the early identification of risk factors for chronic diseases. According to Starfield (2011), PHC strengthens the continuity of care, facilitating ongoing monitoring and the prevention of complications, which is crucial for controlling these diseases. This feature contributes to better clinical outcomes and reduced hospital costs. A key aspect of PHC in the prevention of NCDs is the promotion of healthy lifestyles. Strategies involving health education, encouragement of physical activity, balanced diet, and smoking cessation are effective in reducing the incidence of these conditions (World Health Organization, 2018). PHC enables these actions to be implemented in a contextualized manner, respecting the social and cultural conditions of the population. Care coordination is another pillar of PHC that supports chronic disease prevention. Macinko et al. (2009) emphasize that integrated monitoring across different levels of care prevents service fragmentation, ensuring that the patient receives continuous care, which is especially important for the management of diseases requiring constant monitoring. Studies show that health systems based on strong primary care exhibit better health indicators related to chronic diseases. Paim et al. (2011) show that the presence of Family Health teams reduces mortality from conditions sensitive to primary care, confirming the effectiveness of these strategies in prevention. PHC also plays an important role in identifying and managing the social determinants that influence chronic diseases. Social vulnerability, low education levels, and poverty are factors that hinder treatment adherence and disease control. Primary care enables collaboration with other sectors, such as social assistance and education, promoting intersectoral approaches (Marmot et al., 2008). Another important point is the ease of access to services. PHC is closer to the community, making care more accessible and less costly for users. This proximity increases adherence to preventive and control treatments, preventing disease progression (Shi et al., 2019). Continuous education of professionals working in PHC is essential to ensure the quality of preventive care. Training in clinical management, rational use of medications, and biopsychosocial approaches strengthens the prevention and control of NCDs (Starfield, 2011). Furthermore, the use of information technologies, such as electronic health records and monitoring systems, helps PHC organize care, identify risks, and evaluate the outcomes of preventive interventions (Gulliford et al., 2017). Primary care also plays a vital role in controlling environmental risk factors related to chronic diseases, such as pollution and exposure to toxic agents. Environmental surveillance and education integrated with PHC contribute to reducing the incidence of these conditions (WHO, 2018). In Brazil, the Family Health Strategy (FHS) has been a successful model of primary care that positively impacts chronic disease prevention. Research shows that municipalities with higher FHS coverage present better indicators of chronic disease control (Macinko et al., 2009). User empowerment promoted by PHC is another factor that supports the prevention of NCDs. The active participation of patients in their care and health-related decisions strengthens selfmanagement and adherence to preventive habits (Starfield, 2011). Finally, it is important to emphasize that PHC strengthens the sustainability of the health system by reducing the need for more complex and costly interventions, which is fundamental given the constant rise of chronic diseases (Paim et al., 2011). Conclusion PHC is a key component in the prevention of chronic diseases, promoting continuous, comprehensive, and person-centered care, as an integral patient care policy. Its role in promoting healthy lifestyles, coordinating care, and managing social determinants is indispensable for reducing morbidity and mortality related to these conditions. Investing in the expansion and qualification of primary health care is therefore an essential strategy to ensure the sustainability of the health system and improve the population's quality of life. Intersectoral collaboration, professional training, and the strengthening of the Family Health Strategy must be priorities to achieve these goals. References 1.
