Pregnant women who suffer lapses(忘却) in memory or concentration may no longer be able to blame it on "the bump". The idea that bearing children affects one's brain power---the "baby brain"--is a myth, researchers say.
Their study found no difference in how pregnant women or new mothers scored on tests of thinking speed and memory compared with those who were childless. Writing in the British Journal of Psychiatry, the authors said that pregnant women should be encouraged to stop attributing lapses in memory or logical thinking to their growing baby.
The findings contradict previous studies that claimed women's brains decline in size by up to 4 per cent while they are pregnant, potentially leading to worse performance on tests of memory and oral skills.
Helen Christensen, author of the latest study, said that the effect was "a myth". Professor Christensen's team recruited 1,241 women aged 20-24 in 1999 and 2003 and asked them to perform. a series of tasks. The women were followed up at four-year intervals and asked to perform. the same cognitive tests. A total of 77 women were pregnant at the follow-up assessments, 188 had become mothers and 542 remained childless.
The researchers found no significant differences in cognitive(认知的) change for those women who were pregnant or new mothers during the assessments and those who were not.
"Not so long ago, pregnancy was 'confinement' and motherhood meant the end of career aspirations," Professor Christensen said, "but our results challenge the view that mothers are anything other than the intellectual peers of their contemporaries."
Cathy Warwick, of the Royal College of Midwives, said that the difficulties of pregnancy and motherhood could explain why some women felt absent-minded or tired.
The number of infants in England dying before their first birthday is still greater than in countries such as France, Spain, the Audit Commission says.
The health of pre-school children has not significantly improved despite the Government having spent ￡10 billion, directly or indirectly, since 1998 on improving the health of children under the age of 5 in England. Infant death rates have fallen but are "still relatively high" compared with other European countries.

Next week, as millions of families gather for their Thanksgiving (感恩节) feasts, many other Americans will go without. According to the United States Department of Agriculture, more than 12 million households lack enough food for everyone in their family at some time during the year—including holidays.
Hunger is surprisingly widespread in our country—one of the world's wealthiest—yet the government estimates that we waste almost 100 billion pounds of food each year, more than one-quarter of our total supply.
Reducing this improper distribution of resources is a goal of America's Second Harvest, the nation's largest domestic hunger-relief organization. Last year, it distributed nearly 2 billon pounds of food to more than 23 million people in need.
America's Second Harvest is a network of 214 inter-connected food banks and other organizations that gather food from growers, processors, grocery stores and restaurants. In turn, the network distributes food to some 50,000 soup kitchens, homeless shelters and old people's centers in every county of every state.
A great deal of work is involved in distributing tons of food from thousands of donors (捐赠者) to hundreds of small, nonprofit organizations. Until a few years ago, America's Second Harvest lacked any effective way to manage their inventory. Without accurate and timely information, soup kitchens were sometimes empty while food was left to spoil in loading places.
In 2000, America's Second Harvest began to use a new inventory and financial-management system—Ceres. It is software designed specifically for hunger-relief operations. It is used by more than 100 America's Second Harvest organizations to track food from donation to distribution.
Ceres has helped reduce the spoiling of food and improve distribution. An evaluation found that the software streamlined food banks' operations by 23 percent in the first year alone.
With more accurate and timely reports, Ceres saves time, flees staff members to focus on finding new donors, and promises more efficient use of donations.
Hunger in America remains a troubling social problem. Technology alone cannot solve it. But in the hands of organizations such as America's Second Harvest, it is a powerful tool that is helping to make a difference—and helping more Americans to join in the feast.
According to the passage, the total supply of food in America every year reaches ______.
Mobile phones have proved to ______ with flight instruments and have a negative effect on
