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 Open Access Risk factors for hysterectomy among Mexican-American women in the US Southwest(2003-01) Hautaniemi, Susan I.; Sievert, Lynnette LeidyThe purpose of this study was to assess risk factors associated with a history of hysterectomy among Mexican-American women living in the United States Southwest. Mexican-American women ages 20–74 at time of interview were defined as a subpopulation among adults in the Hispanic Health and Nutrition Examination Survey (HHANES), 1982–1984. Language preference, reproductive history, level of education, poverty status, generation of immigration, marital status, and insurance coverage were examined in relation to risk of hysterectomy using weighted tabulation and logistic regression for data resulting from complex survey designs. Heretofore, language preference has not been a variable considered in relation to risk of hysterectomy. In the HHANES, over 60% of women who spoke English most often rather than Spanish reported a history of hysterectomy. Women who had previously been pregnant were almost four times as likely (odds ratio 3.972) to have had a hysterectomy compared to women who had never been pregnant. Women who expressed any preference for English were twice as likely (odds ratio 2.050) to have had a hysterectomy than were those who responded that they exclusively preferred Spanish. Age, higher levels of education, and higher economic status also increased the risk of hysterectomy. In contrast, reproductive history, marital status, prior tubal ligation, generation of immigration, and health insurance did not have substantial effects on the risk of hysterectomy. This study suggests that, in the future, the effect of language preference should not be overlooked when considering risk factors for hysterectomy.Publication Metadata only Measurement of hot flashes by sternal skin conductance and subjective hot flash report in Puebla, Mexico(2002-01) Sievert, LL; Freedman, RR; Garcia, JZ; Foster, JW; Soriano, MDR; Longcope, C; Franz, CPublication Metadata only Validating signals of ovulation: Do women who think they know, really know?(2005-01) Sievert, LL; Dubois, CPublication Metadata only Publication Metadata only Hot flashes are associated with increased systolic blood pressure.(2005-01) Gerber, LM; Sievert, LL; Pickering, TG; Schwartz, JEPublication Open Access Effects of age, ethnicity and menopause on ambulatory blood pressure: Japanese-American and Caucasian school teachers in Hawaii(2001-01) Brown, DE; Sievert, Lynnette Leidy; Aki, Sue L.; Mills, Phoebe S.; Etrata, Michaelyn B.; Paopao, Rena N. K.; James, GDAmbulatory 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 Metadata only Frequencies and clustering of somatic symptoms at mid-life: Comparing quantitative and qualitative responses(2009-01) Sievert, LL; Obermeyer, CMPublication Open Access Marital status and age at natural menopause: Considering pheromonal influence(2001-01) 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 Open Access Menopause as a measure of population health: An overview(2001-01) Sievert, Lynnette LeidyPublication Metadata only
