Multivitamins  Urged for All Pregnant Women

    A recent study in Tanzaniafound that when pregnant women took vitamins every day, fewer babies were bom too small. Babies that weigh less than two and one-half kilograms at birth have a greater risk of dying. Those that survive are more likely to experience problems with their development. And experts say that as adults they have a higher risk of diseases including heart disease and diabetes. The World Health Organization¹ estimates that every year twenty million babies are bom with low birth weight. Nine out of ten of them are bom in developing countries.

    The new study took place inDar es Salaam. 4,200 pregnant women received multivitamins. The pills contained all of the vitamins in the B group along with² vitamins C and E. They also contained several times more iron and folate than the levels advised for women in developed nations. Pregnant women especially in poor countries may find it difficult to get enough vitamins and minerals from the foods in their diet.

    The scientists compared the findings with results from a group of 4,000 women who did not receive the vitamins. A report by the scientists, from theUnited StatesandTanzania, appeared in the New England Journal of Medicine,³ Wafaie Fawzi of the Harvard University School of Public Health⁴ led the study. None of the women in the study had HTV, the virus that causes AIDS. The scientists reported earlier that daily multivitamins were a low-cost way to reduce fetal deaths in pregnant women infected with ⁵HIV. The earlier work inTanzaniaalso found improvement in the mothers in their number of blood cells known as lymphocytes. Lymphocytes increase the body’s immunity against infection.

    The new study in pregnant women who were not infected with the AIDS virus found that multivitamins reduced the risk of low birth weight. Just under eight percent of the babies bom to women who took the multivitamins weighed less than 2,500 grams. The rate was almost nine and one-half percent in the group of women who received a placebo, an inactive pill, instead of the vitamins. But the vitamins did not do much to reduce the rates of babies being bom too early or dying while still a fetus. Still, the researchers say multivitamins should be considered for all pregnant women in developing countries.

Obesity： the Scourge of the Western World

    Obesity is rapidly becoming a new scourge of the western world, delegates agreed at the 11th European Conference on the issue in Vienna¹ Wednesday to Saturday. According to statements before the opening of the conference _ of 2,000 specialists from more than 50 countries 一 1. 2 billion people worldwide are overweight, and 250 million are obese.
    Professor Bernhard Ludvik of Vienna General Hospital said，“ Obesity is a chronic illness. In Germany，20 per cent of the people are already affected，but in Japan only one per cent. ” But he said that there was hope for sufferers thanks to the new scientific discoveries and medication.
    Professor Friedrich Hopichler of Salzberg said, "We are living in the new age (but) with the metabolism of a stone-age man.²" “I have just been to the United States. It is really terrible. A pizza shop is springing up³ on every corner. We have been overrun by fast food and Coca-Cola-ization. ”⁴
    Many of the experts stressed that obesity was a potential killer. Hopichler said, “Eighty percent of all diabetics are obese，also fifty per cent of all patients with high blood pressure and fifty per cent with adipose tissue complaints. ” "Ten per cent more weight means thirteen per cent more risk of heart disease. Reducing one"s weight by ten per cent leads to thirteen per cent lower blood pressure. ”
    Another expert Hermann Toplak said that the state health services should improve their financing of preventive programs. "Though the health insurance pays for surgery (such as reducing the size of the stomach) when the body-mass index⁵ is more than 40. That is equivalent to⁶ a weight of 116 kilograms for a height of 1.70 meters. One should start earlier. ”
    Ludvik said that prevention should begin in school. “ Child obesity (fat deposits) correlates with⁷ the time which children spend in front of TV sets. ”
　　The consequences were only apparent later on. No more than fifteen per cent of obese people lived to the average life expectancy⁸ for their population group.
