We observed that the prevalence of active pregnant women, as well as duration,
frequency and intensity of their exercise, are lower than that of adult women
and exercise is practiced at an insufficient level to assure the benefits of
an active lifestyle
自己翻的版本
我们观察到积极运动的孕妇的患病率会低于其他的成年女性(运动的时间，频率，强度皆
有连带影响)
还有，运动应维持在不过量的水准以确保对积极生活方式的益处
请问该怎么把 and exercise 后面那句
跟上句接起来
感谢各位高手解答
