Health programs focus on improving the health of individuals and communities. They aim to prevent illness, disability and death. These programs include public health interventions and social and environmental change activities. They are often aimed at addressing social and environmental factors that influence health-related risk behaviors, such as smoking, poor diet and insufficient physical activity. Many health program activities are delivered by professionals, such as physicians, nurses and pharmacists, but some are also carried out by community members, such as family members, friends and neighbors.
Health program activities are designed to address the social determinants of health, which are the economic and social conditions that determine a person’s ability to participate in society and achieve their full potential. These factors influence health-related behavior and can be modified by individual choices, such as eating healthy foods, exercising regularly, avoiding tobacco use, getting regular medical checkups and vaccinating against communicable diseases.
Increasing recognition of the need to improve the health-related behaviour of individuals and groups has resulted in a wide range of public health interventions. Most of these are geared towards the promotion of health-related knowledge, skills and abilities, but they also include the provision of various types of financial or other incentives to encourage desirable health behaviour. Ideally, all such incentives should be based on a cost-benefit methodology that measures resources used and health benefits received in commensurate units.
The success of any health program is often dependent on the participation of a variety of sectors in society, including schools, businesses, law enforcement and transportation, as well as non-governmental organizations. Partnerships can help to ensure that key objectives are achieved, such as ensuring children are healthy and ready to learn, reducing poverty through employment opportunities, eliminating racial disparities and promoting healthy aging.
A wide range of health interventions are available, and each is tailored to specific populations, health goals and local contexts. These include health systems strengthening (policies, financing, organization changes, and training), and social and behaviour change related interventions. In general, the most effective health interventions are those that are based on a scalable technical package. This approach involves selecting a set of evidence-based interventions that, when implemented together, can achieve significant and sustained improvements in a selected risk factor or disease outcome.
