伦敦的免费小报Metro用了耸人听闻的手法来报道最近的那项关于避孕药的研究，我觉得这很容易误导。
找到一篇比较平实的报道：
Slightly higher rates were found among younger women who had used oral contraception, with 20 more deaths per 100,000 among those younger than 30, and four more deaths per 100,000 among 30-39 year olds.
But by the age of 50, the benefits outweighed these modest risks, with 14 fewer deaths per 100,000 among 40-49 year olds; 86 fewer deaths per 100,000 for 50-59 year olds; 122 fewer deaths per 100,000 for 60-69 year olds; and 308 fewer deaths per 100,000 for 70+ year olds.
Hannaford says: "Many women, especially those who used the first generation of oral contraceptives many years ago, are likely to be reassured by our results. However, our findings might not reflect the experience of women using oral contraceptives today, if currently available preparations have a different risk than earlier products."
The authors conclude that their results, derived from a relatively healthy UK study group, show that "oral contraception is not significantly associated with an increased long-term risk of death … indeed a net benefit was apparent." However, they point out that "the balance of risks and benefits may vary globally, depending upon patterns of oral contraception usage and background risk of disease."
我觉得这里面还是缺乏重要数据。十万人里多死亡二十人好像是很小的数字，但要注意，30岁以前的死亡率是很低的。而七十岁以上死亡率很高，308人也就不是多太多。不说出具体数字很难让我信服。
最后几句话更重要。
还有，84-86年联合国的权威性研究主要是把避孕药和乳腺癌联系起来，并且也是指出对年轻女性风险更大。
