长期的亲密伙伴易相互感染坏习惯

For better or for worse, in sickness and in health -- there's a long line of research that associates marriage with reducing unhealthy habits such as smoking, and promoting better health habits such as regular checkups. However, new research is emerging that suggests married straight couples（异性恋伴侣） and cohabiting（同居） gay and lesbian couples in long-term intimate relationships may pick up each other's unhealthy habits as well. University of Cincinnati research into how those behaviors evolve will be presented Aug. 23 at the 106th annual meeting of the American Sociological Association in Las Vegas. Corinne Reczek, a UC assistant professor of sociology, reports three distinct findings into how unhealthy habits were promoted through these long-term, intimate relationships: through the direct bad influence of one partner, through health habit synchronicity（同步性） and through the notion of personal responsibility.

Reczek reports that gay, lesbian and straight couples all described the "bad influence" theme, while in straight partnerships, men were nearly always viewed as the "bad influence."

"The finding that one partner is a 'direct bad influence' suggests that individuals converge（汇聚） in health habits across the course of their relationship, because one individual's unhealthy habits directly promotes the other's unhealthy habits," reports Reczek. An example would be how both partners eat the unhealthy foods that one partner purchases.

"Gay and lesbian couples nearly exclusively described how the habits of both partners were simultaneously promoted due to unhealthy habit synchronicity. For these individuals, one partner may not engage in what they consider an unhealthy habit on their own, but when their desire for such a habit is matched by their partners, they partake in（参加，分享） unhealthy habits," writes Reczek.

"Third, respondents utilized a discourse of personal responsibility to describe how even when they observe their partner partaking in an unhealthy habit, they do not attempt to change the habit, indicating that they were complicit in sustaining their partner's unhealthy habits. The final theme was described primarily by straight men and women," says Reczek.

Reczek adds that the study is among the first of its kind to examine how gay and lesbian couples promote each other's unhealthy habits.
