这项研究基于美国全国女性健康研究的数据，总共调查了 2936 名平均年龄为 45.8 岁的女性；这个数据库是目前为止可用于女性绝经过渡期研究的最大、最多样化和最具代表性的数据库。研究中的性行为是指广义的性行为，既包括性交、口交，也包括性接触和爱抚或自我刺激。After years of questionable choices, Christy is now sober and has her life mostly back on track, although she"s continually tested by her mother, Bonnie. Together, mother and daughter work to overcome their mistakes and build a better future for their family. Both are in positions they never thought they"d be in: Christy is well on her way to becoming a lawyer, while Bonnie is in a healthy romantic relationship and has just gotten married. Through it all, they rely on their support system from AA, including the wise Marjorie, the wealthy and sometimes misguided Jill, the overly emotional Wendy, and Bonnie"s foster sister, Tammy, who was recently released from prison. Collectively, they help each other stay sober in the face of whatever life throws at them.
