In an article published in the journal Evidence Based Nursing, I comment on a recent Cochrane review of general health checks. These are checks that aim to detect risk factors and diseases in healthy people, with the aim of either preventing a disease from developing, or treating a disease earlier in its course. The systematic review of randomised controlled trials (RCTs) of general health checks found that they did not reduce morbidity or mortality, but did increase the number of new diagnoses. The review did though have several limitations. The trials included differed markedly in their definition of what constituted a ‘general health check’ and in the disease they were aiming to address. They also differed in how any newly identified risk factors or disease would be managed. In many studies, the only intervention offered was brief lifestyle advice. Some of the trials were also old, dating from the 1960s. Many of the currently available risk reduction interventions (such as the widespread use of electronic patient records for targeting specific patient groups, tools for measuring individual cardiovascular risk, and low-cost statins for primary prevention) were unavailable at the time most of these trials were carried out.
Primordial prevention and primary prevention are both crucial strategies for promoting health, but they operate at different levels. Primordial prevention aims to address the root causes of health problems and improve the wider determinants of health. It focuses on preventing the emergence of risk factors in the first place by tackling the underlying social, economic, and environmental determinants of health. This involves broad, population-wide interventions such as: Policies that promote healthy food choices: Think about initiatives like taxing sugary drinks to discourage unhealthy consumption, or providing subsidies for fruits and vegetables to make them more accessible. Urban planning that prioritises well-being: This could include creating walkable neighborhoods with safe cycling routes, ensuring access to green spaces for recreation and relaxation, and designing communities that foster social connections. Social programs that address inequality: Initiatives aimed at reducing pov...
