Mice that were born via a c-section put on about 30 percent more weight than their counterparts who'd had a natural birth.

剖腹產(chǎn)出生的小鼠比順產(chǎn)出生的小鼠大約重30%。

Females, specifically, who had been delivered by c-section had gained a staggering 70 percent more weight than the mice born vaginally.

具體來說，剖腹產(chǎn)出生的雌性小鼠比其順產(chǎn)出生的同類超重多達(dá)70%,。

The drastic increase is credited to a difference in the bacteria found in the stomachs of the two groups of mice.

體重明顯增長是因為兩組小鼠腸道細(xì)菌的差異,。

The microbiome, which houses such bacteria, in mice born vaginally progressed normally throughout the course of the study.

能培養(yǎng)此類細(xì)菌的微生物菌群在自然分娩降生的小鼠體內(nèi)生長正常。

However, that of mice born by c-section, matured too quickly at first and then regressed later in their lives.

然而,，剖腹產(chǎn)出生的小鼠起初成熟速度過快,，隨后發(fā)育出現(xiàn)倒退。

Study author Dr Maria Dominguez-Bello said: 'Our study is the first to demonstrate a causal relationship between c-section and increased body weight in mammals.'

研究報告的作者瑪麗亞 多明格斯-貝羅稱：“我們的研究首次證明了剖腹產(chǎn)和哺乳動物體重增加之間的因果關(guān)系?！?/p>

The research team said that c-sections, while critical in about 15 percent of births, are widely overused, citing that 50 percent of births in Brazil, Iran and the Dominican Republic are performed via the operation.

該研究團隊表示,，雖然在人類的生產(chǎn)中約15%的剖腹產(chǎn)是必要的，但很多地方都在濫用剖腹產(chǎn)手術(shù),，例如巴西,、伊朗和多米尼加共和國的剖腹產(chǎn)比例為50%。

They are hopeful that their work will curb unnecessary cesareans and bring down the growing obesity rate in the US.

該團隊希望他們的研究可以扼制不必要的剖腹產(chǎn)手術(shù),，降低美國日益嚴(yán)重的肥胖率,。
