[導(dǎo)讀] 一項新研究顯示,對孩子進行母乳喂養(yǎng)的母親,患卵巢癌的風(fēng)險較低。而且喂母乳的時間越長,對母體免于患這種癌癥的保護也就越大。

眾所周知,卵巢癌以“無聲殺手”而著稱,很多患者僅出現(xiàn)如腫脹感等不明確癥狀,往往在診斷出來時病情已相當(dāng)嚴重。在這項新的研究中,澳大利亞科學(xué)家把493名被診斷出患卵巢癌的婦女,與相似年齡的472名健康女性進行了對照研究。每位婦女都回答了有幾個孩子,以及每個孩子接受母乳喂養(yǎng)的時間有多長等問題。研究結(jié)果顯示,與對孩子進行母乳喂養(yǎng)不到7個月的婦女相比,那些讓孩子接受母乳喂養(yǎng)至少13個月的婦女,患卵巢癌的幾率減少了63%。研究還發(fā)現(xiàn),母親所生的孩子越多,這種效果就越明顯。
發(fā)表在最近出版的《美國臨床營養(yǎng)雜志》上的這項研究稱,那些有3個孩子,且喂母乳時間總共達31個月以上的婦女,要比母乳喂養(yǎng)不到10個月的婦女患此癌的幾率低91%。研究人員指出,過去有許多研究已經(jīng)證明,母乳喂養(yǎng)可降低母親患乳腺癌的風(fēng)險,而這項新研究為母乳喂養(yǎng)對母親的健康有益這一觀點增加了新的佐證。
Ovarian cancer risk is reduced by prolonged lactation: a case-control study in southern China
Background: Ovarian cancer is an important neoplasm that is difficult to diagnose and treat; therefore, prevention is the preferable strategy. Growing evidence indicates a protective effect of breastfeeding on ovarian cancer risk.
Objective: The objective was to investigate the association between lactation and the risk of ovarian cancer among southern Chinese women.
Design: A case-control study was undertaken in Guangzhou, Guangdong Province, between August 2006 and July 2008. A validated and reliable questionnaire was used to obtain information on the months of lactation and number of children breastfed in a sample of 493 incident ovarian cancer patients and 472 hospital-based controls (mean age: 59 y). Logistic regression analyses were performed to assess the association between breastfeeding and the risk of ovarian cancer.
Results: Significant inverse dose-response relations were found for both duration of lactation and the number of children breastfed. The adjusted ORs were 0.09 (95% CI: 0.04, 0.19) for women with ≥31 mo of total lactation and those with ≤10 mo of lactation and 0.38 (95% CI: 0.27, 0.55) for women with ≥3 children breastfed compared with those with one child breastfed.
Conclusion: Prolonged lactation is associated with a lower risk of ovarian cancer in parous Chinese women.
