Why waist circumference is possibly your most important metric in a health screening and why females are at LOWER risk for heart disease.
++++++++++++++++++++++++++++++++++++++++++++++++++
For YEARS health care professionals, like ourselves, have suggested that BMI (Body Mass Index), is an important measurement with respect to body composition and cardio-metabolic health. In fact, we still calculate this measurement in almost all of our health screenings. Despite its widespread use for so many years, I'm sure you're aware that it has its pitfalls.
Despite this measurements uses (it does have its place in health risk assessment protocols), BMI can certainly mislead us as to whether a person is at risk for cardiovascular related illnesses and for this reason can create undue stress and inaccurate diagnosis for people in health care settings. Furthermore, BMI alone should not be the sole measure of heart and vascular health risk.
Why waist circumference?
BMI should really be looked at in conjunction with several other tests relating to body composition. One of the most important being waist circumference.
The waist circumference measurement is an extremely simple measurement to take and gives us one of the most significant indicators of cardio-metabolic health.
Research clearly indicates that obese people with visceral fat accumulation (more common in males) more frequently demonstrate impaired glucose and lipid metabolism compared to those those with subcutaneous fat accumulation (more common in females). So ladies, your thunder thighs are hardly an issue!
You see, the fat around our thighs and bums is mostly sub-cutaneous. For this reason, and several others, both physiological and psycho-social, woman are at a lower risk for heart disease.
It has been suggested that visceral adiposity is present in almost 90% of obese patients with ischemic heart disease. Even in non-obese groups, visceral fat accumulation is highly related to impaired glucose tolerance, dislipidemia and hypertension.
How do we combat visceral fat?
From clinical perspective, aging, s*x hormones, excessive sugar consumption and lack of exercise have been suggested to be the cause for visceral fat accumulation. Practically, these issues are not difficult to address:
1) Limit your sugar intake. Put the Ben & Jerry's Ice Cream DOWN!
2) Manage stress effectively. Wooossaaaah! Meditate!
3) Engage in a balanced and consistent physical activity regime. FYI - Research studies support the efficacy of short-term, high-intensity aerobic exercise training for the reduction of visceral fat in overweight adults.
Over and out....
