Hunger Afflicts One-Sixth of World's People: U.N.
The global economic crisis and high food prices are major reasons why 1.02 billion people (one-sixth of the world's population) don't have enough to eat, says a United Nations' agency report released Friday. Most of those going hungry -- defined as consuming less than 1,800 calories a day -- are in developing nations.
The Food and Agriculture Organization said there are 100 million more people going hungry this year than in 2008, and that more aid and agricultural investment are needed to help people in poor countries get enough to eat, the Associated Press reported.
The largest number of hungry people (642 million) are in Asia and the Pacific region, while the highest rate of hunger (32 percent) is in sub-Saharan Africa.
"The silent hunger crisis, affecting one-sixth of all of humanity, poses a serious risk for world peace and security," said agency Director-General Jacques Diouf, the AP reported.
To highlight the connection between hunger and peace, officials noted that rising prices for staples such as rice caused riots in the developing world last year, the AP reported.
U.S. Gives $6 Billion in New Child Insurance Funding
The U.S. government will give $6 billion in new funding to states and territories to maintain existing Children's Health Insurance Program (CHIP) enrollment and expand their programs.
The new funds were made available by the Children's Health Insurance Program Reauthorization Act of 2009, which provides additional funding for CHIP programs.
Of the $6 billion in new funding, more than $1 billion has been released and the remainder is expected to be allocated by the end of September.
"Through CHIPRA, states and territories will receive additional funds to provide health insurance to 11 million children, including 4 million who were previously uninsured. Parents now have more help if their children fall ill," Health and Human Services Secretary Kathleen Sebelius said in a news release.
CHIP provides health insurance for children in working families whose incomes are too low for either employer-sponsored family plans or private plans, but too high for traditional Medicare.
Undiagnosed Condition Increases Women's Osteoporosis Risk
A delay in diagnosing a menopause-like condition called primary ovarian insufficiency in young women increases their risk of low bone density and osteoporosis later in life, says a U.S. National Institutes of Health study.
The condition occurs in girls and women younger than 40 when their ovaries stop working normally and no longer release eggs or produce estrogen. The main symptom -- irregular or stopped menstrual periods -- is often disregarded by women and their doctors, the study authors said.
