Introduction
As a biological anthropologist I focus on age at menopause and symptom experience at midlife as two aspects of human variation. I am also interested in the evolution of menopause and post-reproductive aging as a human trait. Fieldwork on the topic of menopause has taken me from western Massachusetts to Mexico, Slovenia, Paraguay, Hawaii, London, and Bangladesh.

Publication Do Japanese American women really have fewer hot flashes than European Americans? The Hilo Women's Health Study(2009-01-01) Brown, Daniel E.; Sievert, Lynnette Leidy; Morrison, Lynn A.; Reza, Angela M.; Mills, Phoebe S.Objective Many studies have found a significantly lower frequency of reported hot flashes (HFs) in Japanese and Japanese American (JA) populations, leading to speculation about possible dietary, genetic, or cultural differences. These studies have relied upon subjective reports of HFs. Accordingly, the purpose of this study was to compare both reported and objective HFs measured by sternal and nuchal skin conductance among JA and European American (EA) women. Design Two surveys of hot flash frequencies were carried out among women of either EA or JA ethnicity, aged 45-55, living in Hilo, Hawaii, and not using exogenous hormones. The first was a postal questionnaire (N=325), the second was carried out during a clinical study of hot flashes (N=134). Women in the second group underwent 24-hour ambulatory and 3-hour laboratory monitoring for objective HFs measured through skin conductance at sternal and nuchal sites. Subjective HFs were recorded on the monitor, or in a diary. Results JAs were significantly less likely to report having had HFs in the previous two weeks compared with EAs (postal sample: JAs: 30.9%, EAs: 43.9%, χ2=6.9, p < .01; monitored sample: JAs: 26.1%, EAs: 46.6%, χ2=5.3, p < 0.05). JAs were also significantly less likely to report experiencing other symptoms (15 out of 30 in the postal sample; 6 of 30 in the monitored sample) than EAs. However, JAs did not significantly differ in likelihood of reporting subjective HFs during the 24-hour ambulatory period (JAs: 51.1%, EAs: 55.8%, χ2=0.3, ns), nor in percentage of individuals displaying one or more objective HFs as measured by the skin conductance monitor (JAs: 77.8%, EAs: 72.1%, χ2=0.5, ns). JAs also did not have a significantly fewer number of objective HFs (t=0.2, ns) nor of subjective HFs (t = 0.8, ns) during the monitoring period, and these results were unchanged when analyses controlled for menopausal status and BMI. Conclusions The common finding of fewer reported HFs in people of Japanese ancestry may be a consequence of reporting bias: JAs report fewer symptoms of many conditions compared to people from other ethnic groups. This is likely due to cultural conceptions of what is appropriate to report.Publication Subjective and objective hot flash experience in Sylhet, Bangladesh(2008-01-01) Sievert, LL; Sharmeen, T; Begum, K; Chowdhury, O; Muttukrishna, S; Bentley, GPublication Acre-related differences in health complaints: The Hilo women's health study(2007-01-01) Sievert, LL; Morrison, LA; Reza, AM; Brown, DE; Kalua, E; Tefft, HATPublication Considering a relationship between breast feeding and hot flashes.(2001-01-01) Sievert, LLPublication Gender and medication use: An exploratory, multi-site study(2004-01-01) Obermeyer, CM; Schulein, M; Hardon, A; Sievert, LL; Price, K; Santiago, AC; Lazcano, O; Kirumira, EK; Neuman, MPublication A comparison of menopausal symptoms among women in Sylhet, Bangladesh and Sylheti migrants in London, UK.(2008-01-01) Sharmeen, T; Sievert, L; Begum, K; Muttukrishna, S; Bentley, GRPublication Physiology of the Graafian follicle and ovulation(2004-01-01) Sievert, LLPublication Age at menopause in Puebla, Mexico: methodological considerations.(2002-01-01) Sievert, L; Hautaniemi, SPublication Are cross-population differences in hot flash frequency due to variation in women's awareness of hot flashes?(2010-01-01) Sievert, LL; Begum, K; Sharmeen, T; Murphy, L; Muttukrishna, S; Bentley, GRPublication Sources of information and HRT prescribing practices among gynecologists in Puebla, Mexico(2003-01-01) Mueller, KA; Sanchez, GJZ; Sievert, LL
