イラクのバスラで小児白血病が増加
最近15年でイラク南部で小児白血病が倍増した。石油火災、化学兵器、殺虫剤、道端でのガソリン販売などによる化学物質汚染が原因の可能性がある。1993-2007年に15才未満の子どもの白血病が698人発病した。2006年に最も多い211人だった。10万人あたりの発症率で3から81/2 へと増加した。比較として欧米では10万人あたり4〜5、オマーンやクウェートなどの中東の国では2〜3 である。

画像Cases in Basra more than doubled over 15 years, research shows.

THURSDAY, Feb. 18 (HealthDay News) -- Childhood leukemia rates more than doubled in a southern Iraq province over a 15-year period, although the exact cause for the increase is unclear, researchers say.

Possible reasons why so many kids in the province of Basra became ill include exposure to chemicals from petroleum fires, gasoline sold by children on the side of the road, chemical weapons and pesticides, the authors of the new study noted.

Researchers at the University of Washington in Seattle found 698 documented cases of leukemia in the province among children under the age of 15 during the period between 1993 and 2007. The highest number -- 211 -- occurred in 2006.

"By using a hospital cancer registry, we were able to measure a jump in leukemia rates from three per 100,000 youngsters in the first part of our study period, to a rate of almost 81/2 in the final three years," study author Amy Hagopian, of the University of Washington, said in a university news release.

By comparison, leukemia rates in Europe and the United States ranged from four to five per 100,000, and in the Middle Eastern countries of Oman and Kuwait the numbers ranged from two to three per 100,000. Basra and the surrounding region played major roles in three consecutive wars, the latter two with the United States and its allies.

The findings are published online Feb. 18 in the American Journal of Public Health.

Abstract

Objectives. Through a sister-university relationship between the University of Basrah and the University of Washington, we analyzed Ibn Ghazwan Hospital's leukemia registry data to evaluate trends in childhood leukemia since 1993.

Methods. We documented leukemia cases among children aged 0 to 14 years for each of the last 15 years. Population data were obtained from a 1997 census and various subsequent estimates to calculate rates.

Results. We observed 698 cases of childhood leukemia between 1993 and 2007, ranging between 15 cases (2.6 per 100000 annual rate) in the first year and 56 cases (6.9 per 100000 annual rate) in the final year, reaching a peak of 97 cases in 2006 (12.2 per 100000 annual rate).

Conclusions. Childhood leukemia rates in Basrah more than doubled over a 15-year period. The test for trend was significant (P=.03). Basrah's childhood leukemia rate compared unfavorably with neighboring Kuwait and nearby Oman, as well as the United States, the European Union, and other countries.
