May 31, 2006 -- The U.S. is less healthy than its northern neighbor Canada, according to a new study.

The study appears in July's American Journal of Public Health. The researchers included Karen Lasser, MD, MPH, of Harvard Medical School and the medicine department at the Cambridge Health Alliance in Massachusetts.

Data was gathered by Statistics Canada (the Canadian census office) and the U.S. National Center for Health Statistics, a branch of the CDC. Between November 2002 and March 2003, interviews were done by telephone with 3,505 Canadians and 5,183 U.S. residents.

The results: "With the important exception of having lower rates of cigarette smoking, U.S. respondents were less healthy than Canadians, with higher rates of obesity, physical inactivity, diabetes, hypertension (high blood pressure), arthritis, and chronic obstructive pulmonary disease," write Lasser and colleagues.

U.S., Canadian Health

Here's a closer look at the gap between the U.S. and Canada on various health conditions:

  • Obesity: 20.7% of U.S. respondents; 15.3% of Canadian respondents
  • Sedentary lifestyle: 13.6% of U.S. respondents; 6.5% of Canadian respondents
  • Diabetes: 6.7% of U.S. respondents; 4.7% of Canadian respondents
  • High blood pressure: 18.3% of U.S. respondents; 13.9% of Canadian respondents
  • Arthritis: 17.9% of U.S. respondents; 16% of Canadian respondents
  • Chronic obstructive pulmonary disease (COPD): 1.9% of U.S. respondents; 1% of Canadian respondents
  • Current daily smoking: 16.8% of U.S respondents; 19% of Canadian respondents

Heart disease, depression, and overweight BMI that falls short of obesity were similar in the U.S. and Canada, the study shows.

Health Care Findings

The survey also covered health care topics including routine screening, access to medical care, and satisfaction with medical care. Canada has a universal health insurance program; the U.S. doesn't.

"Compared with Canadians, U.S. residents are one-third less likely to have a regular medical doctor, one-fourth more likely to have unmet health care needs, and are more than twice as likely to forgo needed medicines," write Lasser and colleagues.

They add that "problems accessing medical care are particularly dire for the U.S. uninsured," and that while both countries had racial gaps in health, those gaps were wider in the U.S.

Your level is currently

If the level is below 70 or you are experiencing symptoms such as shaking, sweating or difficulty thinking, you will need to raise the number immediately. A quick solution is to eat a few pieces of hard candy or 1 tablespoon of sugar or honey. Recheck your numbers again in 15 minutes to see if the number has gone up. If not, repeat the steps above or call your doctor.

People who experience hypoglycemia several times in a week should call their health care provider. It's important to monitor your levels each day so you can make sure your numbers are within the range. If you are pregnant always consult with your health care provider.

Congratulations on taking steps to manage your health.

However, it's important to continue to track your numbers so that you can make lifestyle changes if needed. If you are pregnant always consult with your physician.

Your level is high if this reading was taken before eating. Aim for 70-130 before meals and less than 180 two hours after meals.

Even if your number is high, it's not too late for you to take control of your health and lower your blood sugar.

One of the first steps is to monitor your levels each day. If you are pregnant always consult with your physician.
