It’s not too late . . .
Let’s face it. Most young people don’t lead such healthy lifestyles. Due to a variety of factors, they’re more likely to smoke, overindulge in unhealthy food and alcohol (think of your college days), and often don’t exercise much. The prevalence of obesity among young people has also hit all time highs in many countries.
Each of these unhealthy behaviors alone damages the body, in particular the heart. In fact, unhealthy lifestyle choices synergistically cause blockages in the main blood vessels supplying blood to the heart. Fortunately, in most cases it takes decades for significant heart disease to develop. That means that we have ample opportunity to get our acts together.
That’s exactly what the Coronary Artery Risk Development in Young Adults (CARDIA) study published in Circulation set out to prove. CARDIA study researchers followed over 3500 young adults (age 18-30) over 20 years. At baseline, fewer than 10% of the study participants were keeping all 5 healthy lifestyle behaviors mentioned above (not smoking, not drinking too much alcohol, exercising, keeping a healthy diet, and keeping a healthy weight). At the end of the study, roughly 25% of the participants added at least one healthy lifestyle factor; unfortunately 40% kept fewer.
The good news for those who did improve was that for each healthy factor that was added, the risk of calcification in the blood vessels supplying the heart (which is a good predictor of heart disease) decreased by 15%. Conversely, each decrease in healthy lifestyle behaviors increased the risk of heart disease by 17%.
The bottom line is that if you’re young, even if you haven’t been living the healthiest life until now, it isn’t too late to change things around. Even making small changes can yield great benefits. On the flip side, if you used to be slim, more active, and eat a healthier diet, but have strayed over the years, then you should realize that real damage is being done and try to turn things around.
