Only 10 percent of U.S. adults have low heart risk

Ninety percent of American adults have at least one risk factor for heart disease, researchers reported on Monday.

Virtually all Americans either have high blood pressure, high cholesterol, high blood sugar, are overweight, smoke or exercise too little, the team led by the Centers for Disease Control and Prevention reported.

“Unfortunately, the limited strides that were made toward this goal during the 1970s and 1980s were eroded by the increases in excess weight, diabetes and hypertension during more recent decades,” the CDC’s Dr. Earl Ford, who led the study, said in a statement.

Ford’s team looked at four national studies covering tens of thousands of Americans aged 25 to 74.

Only 10 percent had low risk scores in all five categories, they reported in the journal Circulation.

“Until the early 90s, we were moving in a positive direction, but then it took a turn and we’re headed in a negative direction,” said Ford.

“When you look at the individual factors, tobacco use is still headed in the right direction and so are cholesterol levels, although that has leveled off. The problem is that blood pressure, BMI (body mass index, a measure of obesity) and diabetes are all headed in the wrong direction.”

Heart disease is the No. 1 killer in the United States and many other countries.

Healthy Eating

[media id=6 width=500 height=400]

Healthy Eating makes you feel better and look better. This video by syndicated columnist Rita Heikenfeld shows you recipes, cooking tips and is a guide to healthy eating.

For an overall eating plan, consider the DASH eating plan. “DASH” stands for “Dietary Approaches to Stop Hypertension,” a clinical study that tested the effects of nutrients in food on blood pressure. Study results indicated that elevated blood pressures were reduced by an eating plan that emphasizes fruits, vegetables, and lowfat dairy foods and is low in saturated fat, total fat, and cholesterol. The DASH eating plan includes whole grains, poultry, fish, and nuts and has reduced amounts of fats, red meats, sweets, and sugared beverages.

A second clinical study, called “DASH-Sodium,” looked at the effect of a reduced dietary sodium intake on blood pressure as people followed either the DASH eating plan or a typical American diet. Results showed that reducing dietary sodium lowered blood pressure for both the DASH eating plan and the typical American diet. The biggest blood pressure-lowering benefits were for those eating the DASH eating plan at the lowest sodium level (1,500 milligrams per day).

The DASH-Sodium study shows the importance of lowering sodium intake whatever your diet. But for a true winning combination, follow the DASH eating plan and lower your intake of salt and sodium.

U.S. pre-term babies die despite medical care: study

Very early pre-term babies kept alive with ventilators, chest tubes and drugs to support the heart may live a little longer than they did 10 years ago, but are just as likely to die before ever going home, U.S. researchers reported on Monday.

Their study suggests the emotionally taxing and expensive care given these tiny newborns, delivered at 22 to 24 weeks gestation, does not in the end save their lives. Babies born at 22 weeks included in the study all died as infants, regardless of care.

“This is a very difficult ethical dilemma for everyone involved,” Pamela Donohue of Johns Hopkins Childrens Center in Baltimore, who led the study, said in a telephone interview.

Most pregnancies last about 40 weeks, and babies born earlier than 37 weeks of pregnancy are considered premature.

Donohue’s team studied 160 women who gave birth at 22-24 weeks during separate two-year periods — 1993-1995 and 2001-2003.

Those who gave birth during the current decade were more likely to receive higher-level care around the time of delivery, including sonograms, antibiotics and steroids to help with fetal lung development.

After birth, their children were more likely to be put on ventilators, drugs to boost heart and blood pressure rates and to have chest tubes inserted.

Infants born in 2001-2003 lived longer on average — seven days, compared to two days in the 1990s.

But mortality rates did not fall, and the researchers urged greater discussion and further study both on intervention and the degree of suffering imposed on children, their families and healthcare providers.
