He and his colleagues then pulled data from the diaries about how many hours the women were spending in various activities, how many calories they likely were expending in each of those tasks, and how the activities and associated energy expenditures changed over the years.

接下来，阿彻博士和同事们开始从这些日记中提取信息，以确定美国女性在各项家务上花费的时间、消耗的热量以及这么多年来这些家务和与之相关的能量消耗有了怎样的变化。

As it turned out, their findings broadly echoed those of the occupational time-use study. Women, they found, once had been quite physically active around the house, spending, in 1965, an average of 25.7 hours a week cleaning, cooking and doing laundry. Those activities, whatever their social freight, required the expenditure of considerable energy. (The authors did not include child care time in their calculations, since the women’s diary entries related to child care were inconsistent and often overlapped those of other activities.) In general at that time, working women devoted somewhat fewer hours to housework, while those not employed outside the home spent more.

最终，他们的发现和此前对劳动者如何分配时间的研究所得出的结论大体相同。以前，美国女性曾在家中从事相当多的体力劳动。在1965年，她们花在清扫、做饭和洗衣服上的时间平均为每周25.7个小时。无论借助怎样的工具，这些家务都会消耗相当多的能量。（研究者们没有把照看孩子的时间计算在内，原因是这些女性在照看孩子方面的记录存在矛盾而且经常和其他家务重叠在一起。）总的来说，当时职业女性在家务上花的时间较少，而家庭主妇在这方面所花的时间则较多。
