“An additional four years of education lowers five-year mortality by 1.8 percentage points; it also reduces the risk of heart disease by 2.16 percentage points, and the risk of diabetes by 1.3 percentage points” (Cutler & Lleras-Muney, 2006).
Education has a strong positive relationship with health status. Its effect is facilitated through several different pathways. Let’s explore them.
A basic education develops individuals’ skills in crucial areas such math, reasoning, problem solving, and literacy. These abilities impact income potential and job security, which in turn are components of socioeconomic status – another determinant of health. These skills are also important for people to feel like they have a sense of control over their lives, so that they can be self-determining. The less control people have over their circumstances, the more their health suffers.
More directly, literacy allows people to find and understand information related to their health. On the most obvious level, it ensures that patients are able to read and follow instructions on a prescription. However, people with higher education may also tend to engage in more health-promoting behaviours, such as avoiding smoking, being physically active, and eating a healthy diet. Research work on the concept of “health literacy” tries to elicit this empowerment towards health status (Nutbeam, 2000).
In developing countries, it is said that if you ‘educate a girl, you educate an entire family.’ This is because in these situations, women manage domestic household affairs and make decisions that can impact the health of the entire family. For example, educating women about the use of oral rehydration therapy in Bangladesh has drastically reduced infant mortality in that country (Chowdhury, Karim, Sarkar, Cash, & Bhuiya, 1997). Educating girls in math can later help women balance a household budget. Hygiene practices, such as hand washing before preparing or eating food, can also be taught in school.
Canada has a strong education system, with secondary school students consistently placing in the top 10 countries globally for skills such as math, reading, and science (OECD, 2012). 86.7% of Canadians aged 25-29 graduated high school, and 62.6% of those aged 25-54 have a university degree (CANSIM, 2006). The difference literacy and higher education can make is huge. 7.8% of high school graduates are unemployed, while only 4.4% of those with a university education are out of work (CANSIM, 2014). 19% of Canadians with less than a high school education rank their health as ‘excellent,’ compared to 30% of university graduates (Public Health Agency of Canada, 2013). It is clear that investing in education is an important part of improving health status across the globe.
