Homogamy and imprinting-like effect on mate choice preference for body height in the current Japanese population

Ann Hum Biol. 2012 Jan;39(1):28-35. doi: 10.3109/03014460.2011.635695. Epub 2011 Dec 5.

Abstract

Background: Homogamy for body height has been repeatedly documented in Western societies. Nevertheless, the underlying mechanism is unclear and the reasons for its apparent absence in non-Western societies remain unexplained.

Aim: This study investigates spousal correlation and mate preference for height in the Japanese population.

Subjects and methods: This study analyses self-reported data on the height of individuals, their parents and their ideal marriage partners, collected by a series of questionnaires on university students.

Results: In contrast to a previous study, this study found a significant positive correlation between the heights of Japanese spouses, after controlling for age. It also found a positive correlation between the heights of subjects and of their ideal partners, suggesting that an individual's self-referent preference may contribute to the observed homogamy for height. However, a subject's preference is also influenced by the height of his/her opposite-sex--but not same-sex--parent, where this effect is more prominent in male subjects.

Conclusion: This study shows that homogamy for body height is present in the current Japanese population and that it may in part result from an individual's preference. It also indicates a possible role of a sexual imprinting-like mechanism in human mate choice.
