Men rule on the playing field: they can generally run faster,
lift more, and throw things farther than women can. In medical terms,
though, men are the weaker sex, reports the January 2010 issue of
Harvard Men’s Health Watch. Why? It depends on a complex mix of
biological, social, and behavioral factors.
Biological factors include the fact that, compared with men, women
have substantially higher levels of HDL (good) cholesterol, which
protects against heart disease. In addition, excess weight – although
common in both sexes – is more of a problem for males. Women tend to
carry excess weight on their hips and thighs, while men add it to their
waistlines. This abdominal obesity is more damaging to health than
lower-body obesity, sharply increasing the risk of heart attack and
stroke.
Among the important social factors are a set of traits that tend to
be more common in men than in women. Type A behavior, stress, hostility,
and anger have all been implicated as heart disease risk factors.
Conversely, women generally have larger and more reliable social
networks than men. Strong interpersonal
relationships and support
networks reduce the risk of many maladies.
As for behavioral factors, smoking, drinking, and drug abuse are
traditionally male problems. Although the gap has narrowed to some
degree, males still dominate in these self-destructive habits. Women
also reap the health benefits of better diets. Meat-and-potatoes guys
don’t eat veggies – but they should.
Harvard Men’s Health Watch offers 10 ways for men to achieve long and healthy lives. Among them are these:
Avoid tobacco.
Eat more whole grains, fruits, and vegetables, and less red meat,
whole-milk dairy products, high-sodium processed foods, sweets, and
trans fats.
Exercise regularly, at least 30 minutes of moderate exercise nearly every day, including strength and balance work.
Reduce stress, get enough sleep, and build social ties and community support.
Seek joy and share it with others.
How old are your arteries? From the Harvard Heart LetterArteries age
slowly and gracefully when nurtured with daily exercise, a healthful
diet, and good relationships with family and friends. They age faster
when they’re constantly assaulted by cigarette smoke, foods laden with
saturated and trans fats, chronic stress, and other traumas. Knowing the
true age of your arteries can give a clearer picture of overall heart
health.
Two available tools estimate artery “age” based on physical
characteristics. Measurement of these physical variables in many people
has allowed researchers to identify ranges for each that correspond to
different chronological ages. A third tool relies on age, cholesterol,
and blood pressure information.
Pulse wave velocity. Each heartbeat sends a wave of blood through the
arteries. The stiffer the arteries, the faster this wave travels.
Measuring the speed of the pulse wave provides information about how
stiff or how flexible the arteries are. This is usually done in a
doctor’s office.
Carotid intima-media thickness. The innermost layer of an artery’s
wall is called the intima. The media is the middle layer. The thicker
the intima and the media, the more likely the artery is choked with
cholesterol-filled plaque. Using ultrasound, a doctor can measure the
thickness of the intima and media in the carotid arteries, located in
the neck.
Framingham score. Data from the Framingham Heart Study have helped
researchers create a cardiovascular risk profile. With answers to a few
questions, this tool estimates a person’s chances of having a heart
attack or stroke, needing bypass surgery or angioplasty, or developing
peripheral vascular disease or heart failure. It also estimates the age
of the blood vessels.
