Healthy lifestyle and longevity Healthy You
How is it that the Africans (To be specific, Nigeria) spends the most money on healthcare, and yet still has the one of the lowest life expectancies of all developed nations? (To be specific: ₦3,407,500.00 per capita, 79 years, and 31st.)
Maybe those of us in healthcare have been looking at it all wrong, for too long.
Researchers from the Harvard T.H. Chan School of Public Health conducted a massive studyof the impact of health habits on life expectancy, using data from the well-known Nurses’ Health Study (NHS) and the Health Professionals Follow-up Study (HPFS). This means that they had data on a huge number of people over a very long period of time. The NHS included over 78,000 women and followed them from 1980 to 2014. The HPFS included over 40,000 men and followed them from 1986 to 2014. This is over 120,000 participants, 34 years of data for women, and 28 years of data for men.
The researchers looked at NHS and HPFS data on diet, physical activity, body weight, smoking, and alcohol consumption that had been collected from regularly administered, validated questionnaires.
But What Exactly is a Healthy Life?
These 5 areas were chosen as a result of previous studies that have shown them to own an oversize impact on the risk of premature death. Here is however these healthy habits were outlined and measured:
These five areas were chosen because prior studies have shown them to have a large impact on the risk of premature death. Here is how these healthy habits were defined and measured:
1. A healthy diet, which was calculated and rated based on the reported intake of healthy foods like vegetables, fruits, nuts, whole grains, healthy fats, and omega-3 fatty acids, and unhealthy foods like red and processed meats, sugar-sweetened beverages, trans fat, and sodium.
2. Healthy physical activity level, which was measured as at least 30 minutes per day of moderate to vigorous activity daily.
3. Healthy body weight, defined as a normal body mass index (BMI), which is between 18.5 and 24.9.
4. Smoking, well, there is no healthy amount of smoking. “Healthy” here meant never having smoked.
5. Moderate alcohol intake, which was measured as between 5 and 15 grams per day for women, and 5 to 30 grams per day for men. Generally, one drink contains about 14 grams of pure alcohol. That’s 12 ounces of regular beer, 5 ounces of wine, or 1.5 ounces of distilled spirits.
Researchers also looked at data on age, ethnicity, and medication use, as well as comparison data from the National Health and Nutrition Examination Surveys and the Centers for Disease Control and Prevention’s Wide-Ranging Online Data for Epidemiologic Research.
So what is the problem?
we tend to spend outlandishly on developing fancy drugs and other treatments for diseases, rather than on trying to prevent them. This is a big problem.
Experts have suggested that the best way to help people make healthy diet and lifestyle change is at the large-scale, population level, through public health efforts and policy changes. (Kind of like motorcycle helmets and seat belt legislation…) We have made a little progress with tobacco and trans-fat legislation.
There’s a lot of pushback from big industry on that, of course. If we have guidelines and laws helping us to live healthier, big companies aren’t going to sell as much fast food, chips, and soda. And for companies hell-bent on making money at the cost of human life, well, that makes them very angry.
