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 Effects of age, ethnicity and menopause on ambulatory blood pressure: Japanese-American and Caucasian school teachers in Hawaii(2001-01-01) Brown, Daniel E.; Sievert, Lynnette Leidy; Aki, Sue L.; Mills, Phoebe S.; Etrata, Michaelyn B.; Paopao, Rena N. K.; James, Gary D.Ambulatory blood pressure (BP) measurements of 120 female teachers of Japanese-American or Caucasian ethnicity working in public schools located in Hilo, Hawaii, were recorded. BP was measured at 15-min intervals during waking hours and 30-min intervals during sleep over a 24-hr period that included a full work day. These measurements were averaged during three daily settings: at work, at home while awake (“home”), and during sleep. ANCOVAs using ethnicity as a predictor variable of BP, with age and the body mass index (BMI) as covariates, show a significant interaction effect between age and ethnicity in some daily settings. Among Japanese-Americans partial correlations between age and systolic BP controlling for the BMI are significant in these settings, while among Caucasians none of the correlations are significant. Menopausal status is not significantly related to BP when age is controlled in analyses. There was no significant ethnic difference in number of symptoms reported, including frequency of “hot flushes/flashes,” within the past two weeks. Those who reported hot flushes had significantly elevated BP in waking settings but not during sleep. The greater increase in BP with age in Japanese-Americans may be related to their elevated risk for development of hypertension. The lack of a significant relationship between menopausal status and BP may be due to the high rate of usage of hormonal replacement therapy in this sample, as well as an unusually high rate of hysterectomy.Publication Frequencies and clustering of somatic symptoms at mid-life: Comparing quantitative and qualitative responses(2009-01-01) Sievert, LL; Obermeyer, CMPublication Publication The effect of migration on ovarian reserve in adult Bangladeshi women(2009-01-01) Begum, K; Muttukrishna, S; Sharmeen, T; Sievert, LL; Chowdhury, O; Bentley, GRPublication Menopause as a measure of population health: An overview(2001-01-01) Sievert, Lynnette LeidyPublication The medicalization of female fertility - Points of significance for the study of menopause(2003-01-01) Sievert, LLPublication Measurement of hot flashes by sternal skin conductance and subjective hot flash report in Puebla, Mexico(2002-01-01) Sievert, LL; Freedman, RR; Garcia, JZ; Foster, JW; Soriano, MDR; Longcope, C; Franz, CPublication Hot flashes are associated with increased systolic blood pressure.(2005-01-01) Gerber, LM; Sievert, LL; Pickering, TG; Schwartz, JEPublication Marital status and age at natural menopause: Considering pheromonal influence(2001-01-01) Sievert, Lynnette Leidy; Waddle, Diane; Canali, KristophorMarried women generally report a later mean age at menopause. The results reported here, from a study carried out in Greene County, New York, are no exception. Married and widowed women report a later mean age at natural menopause compared to single and divorced women (P < 0.05). To better understand the relationship between marital status and age at menopause, possible mechanistic and confounding variables are examined, in particular parity, sexual activity, smoking habits, level of education, and income. Parity and income 10 years prior to interview are significant factors, along with marital status, that explain part of the variation in age at natural menopause. An alternative explanation is the pheromonal influence of a male in the household. This would explain the consistency of results across populations. This pilot study supports further biochemical investigation.Publication Validating signals of ovulation: Do women who think they know, really know?(2005-01-01) Sievert, LL; Dubois, CA
