That dietary fat increases breast cancer risk has been strongly supported by international data collected among developed countries during the past few decades. Population aggregates with elevated lipid intake have tended to report elevated breast cancer incidence and mortality. This study is an ecological analysis of the association of various indicators of lipid intake with breast cancer mortality in 65 county-wide population aggregates in the People's Republic of China. Although the result is consistent with a positive association between lipid intake and breast cancer risk, the observed association is weaker than the association previously observed. This finding provides only modest support for the possibility of a diet-breast cancer link.
过去几十年间，在发达国家收集的国际数据有力地支持了膳食脂肪会增加患乳腺癌风险这一观点。脂质摄入量较高的人群往往报告乳腺癌发病率和死亡率也较高。本研究是一项生态学分析，旨在研究中华人民共和国65个县级人群中各种脂质摄入指标与乳腺癌死亡率之间的关联。尽管结果与脂质摄入和乳腺癌风险之间的正相关一致，但观察到的关联比之前观察到的关联要弱。这一发现仅为饮食与乳腺癌之间存在联系的可能性提供了适度的支持。
