I try not to be a complainer about school on my blog. I’ll drop the occasional hint that I am stressed or that school is difficult, but let’s be real here: I am in medical school and that is to be expected. The last few weeks of school have been legitimately hard for me because I wasn’t enjoying the material. Every second of studying felt like work and by the end of the module, I was left questioning if medicine was something I was truly passionate about. It is so nice to be reminded that the answer to that question is yes! We have moved from studying infectious diseases to the cardiovascular system, and I am really enjoying. There is still a lot of work, I am still stressed and school is still difficult, but I am enjoying learning again!
The best part of this block is the practicality of it (many of my future patients will have heart disease, but I am unlikely to see a rare fungal disease that I just spent hours memorizing!). I am interested in primary care and preventative medicine, and there is no better example of the importance of lifestyle interventions than in the cardiovascular system. First some sobering statistics, then some good news, and then I have a question at the end that I would love your feedback on!
Some sobering stats:
- The newest reports show that 68% of American adults and 20% of American children are overweight (BMI > 25). The super obese (BMI > 50) is the fastest growing segment of the population. By 2025, 50% of the US will be obese (BMI > 30). This is some scary stuff! While it is commonly assumed that obesity is an American epidemic, that is not all true either. It is more prevalent here, but upward trends are beginning in many other countries as well.
- Obesity is the 2nd leading cause of cardiovascular related deaths, second to cigarette smoking. This kills more than 400,00 people per year!
- Cardiovascular disease is the leading cause of death in the US, and actually kills more women than men annually.
- Cardiovascular disease and hypertension, when combined, cost more in health care dollars than cancer and trauma-related injury.
- The estimated annual cost of cardiovascular disease, including productivity hours lost, is $287 billion dollars.
- The biggest gains in cardiovascular health come from just adding minimal physical activity. If the population is divided into five groups, 1 being sedentary and 5 being most active, a person reduces their risk of cardiovascular disease the most by moving from the first to second quintile. What does this mean? You don’t have to run a marathon to be healthy. You don’t even have to run! Just go for a walk at lunch time or before dinner a few times a week! Five 30-minute sessions of light aerobic activity is enough to cut your risk of heart disease in half. There are added gains of even more activity, but the biggest boost is the first step.
- One in seven new cases of type II diabetes can be prevented by a 7% weight loss and the addition of 150 minutes of physical activity per week. Lifestyle interventions have been proven more effective than medication therapy. 7% weight loss is pretty modest – 14lb for a 200lb person. A person can lose up to 20 lb in one year simply by cutting 125 calories (the equivalent of a can of soda or an extra slice of toast at breakfast). Again, not a major step for huge benefit.
- Cardiovascular deaths can be cut in half by national and individual efforts to reduce major preventable risk factors (smoking, obesity, high blood pressure, high cholesterol, etc.) If you are a nerd like me, check out the Million Hearts Initiative.
