In general, Asian women have been reported to experience lower rates of symptoms during their menopausal transition compared with women from Western countries. Also, studies showed that the patterns of menopausal symptoms experienced by Asian women also differed from their Western counterparts. Recently, researchers began to argue that these findings cannot be generalized to all Asian midlife women because of the diversity within Asian populations and because they are inconsistent. Yet, very few studies compared Asian women's menopausal symptom experience by sub-ethnicity and very little is known about the sub-ethnic variations especially within Asian American women. The purpose of this study was to compare the menopausal symptom experiences of five sub-ethnic groups (Chinese, Korean, Asian Indian, Filipino, and others) of Asian American women in the U.S. A feminist perspective was used to theoretically guide the data collection, analysis, and interpretation process. For example, this study was based on the feminist assumption that the inadequate management of menopausal symptoms reported by Asian American women, stems not only from biology, but also from these women's continuous historical interactions with their environment, as well as biases that reflect the ways that they and their health care providers view the world. The study was announced to both Internet communities/groups for midlife women and Internet communities/groups for Asian American women in the U.S. Ninety one self-identified Asian American midlife women aged 40 to 60 years who could read and write English were recruited using a quota sampling method. The women were asked to fill out the Internet survey questionnaire that included questions about background characteristics, ethnic identity, and health and menopausal status, and the Midlife Women's Symptom Index. The data were analyzed using descriptive and inferential statistics, including ANOVA and chi-square analyses. The findings indicated that there were significant sub-ethnic variations in the most frequently reported symptoms and the most severe symptoms. Also, the findings indicated that there were significant differences in the number of physical, psychosomatic, and psychological symptoms by sub-ethnicity and that there were significant differences in the total severity scores of menopausal, psychosomatic, and psychological symptoms by sub-ethnicity. Especially, the findings indicated that the menopausal symptom experience of Filipino women was significantly different from that of Korean and Chinese women. The perceived causes of and management strategies for menopausal symptoms also differed according to sub-ethnicity. Some of these findings are consistent with those of previous studies; others are not. These findings may stem from the unique cultural backgrounds within each of the major Asian American ethnic groups, and may not be easily generalizable to other Asian American women, especially those with low socioeconomic status. The findings suggest further in-depth studies on sub-ethnic variations in menopausal symptom experiences with a large number of Asian American women from diverse sub-ethnic groups. The findings also suggest that researchers and clinicians should respect this diversity when providing health care for Asian American women.
