Brown Adipose Tissue Activity and Childhood Exposure to Cold Are Associated With Hot Flashes at Menopause
OBJECTIVE: Hot flashes (HFs) are experienced as sudden sensations of heat. We hypothesized that brown adipose tissue (BAT) activation could increase the likelihood of HFs in winter. The aim of this study was to test whether women with more BAT activity were more likely to experience self-reported or biometrically measured HFs. METHODS: Women aged 45-55 years (n = 270) participated in face-to-face interviews and anthropometric and ambulatory measu…
Hand grip strength, standing balance, and rapid foot tapping in relation to the menopausal transition in Campeche, Mexico
OBJECTIVES: This cross-sectional study investigated menopause status in relation to hand grip strength, standing balance, and rapid foot tapping. A secondary aim was to examine the relationship between physical performance and urban/rural residence with a focus on habitual daily tasks. METHODS: Maya and non-Maya women (40-60 years) were drawn from urban and rural sites in Campeche, Mexico (n = 543). Demographic, reproductive, and lifestyle inform…

When Does Fertility End? The Timing of Tubal Ligations and Hysterectomies, and the Meaning of Menopause
We applied a biocultural lens to examine the temporal order of biological, behavioral, and medical events related to fertility across the female reproductive lifespan in three sites, two in Mexico and one in the United States. Using a mixed-method design, we expanded our thinking about the end of fertility in order to examine the timing of hysterectomies and tubal ligations. We discovered that menopause is not the end of fertility for a surprisin…
Hot Flashes Associated with Menopause in the State of Campeche, Mexico
The purpose of this study was to apply a phenomenological perspective in order to better understand hot flashes among 87 Maya, 60 non-Maya, and 8 uncategorized women from rural and urban communities in the state of Campeche, Mexico. We combined in-depth interviews with ambulatory hot flash monitors to show that while the majority of women had biometrically measurable sternal (75%) and nuchal (81%) hot flashes, they were less likely to report hot …
Physical activity level and body composition in a multiethnic sample of school children in Hawaii
PAL and PTI are moderately related to adiposity measures, and there are no ethnic differences in physical activity or fitness measures in this sample
Variation in levels of AMH among Maya and non‐Maya women in Campeche, Mexico
OBJECTIVES: The purpose of this study was to examine anti-Müllerian hormone (AMH) levels among women of Maya and non-Maya ancestry in the city of Campeche, Mexico. Levels of AMH can potentially predict age at menopause. Previous studies have indicated an early mean age at menopause among the Maya. MATERIALS AND METHODS: Women aged 40-60 (n = 97) participated in semistructured interviews, anthropometric measures, and blood samples. Maya/non-Maya e…
Ambulatory blood pressure and blood lipids in a multiethnic sample of healthy adults
OBJECTIVES: Elevated blood pressure (BP), elevated serum cholesterol, and aberrant lipoprotein fractions (low levels of high-density lipoprotein (HDL) and high levels of low-density lipoprotein fractions and triglycerides) have all been used as measures that assess the "metabolic syndrome" and more recently in indexes of allostatic load, which are designed to assess the degree of integrated metabolic pathology. While there are ample data regardin…
Relationships between diurnal changes in blood pressure and catecholamines among Filipino‐American and European‐American women
The relationships between diurnal BP and catecholamine variations differ by ethnicity. Further research is needed to better understand the mechanisms behind the differences and to evaluate whether this vascular tonic relationship has been the focus of natural selective processes
Voices From the Hilo Women's Health Study
Our purpose in conducting this qualitative study was to examine how a multiethnic sample of women living in Hilo, Hawai'i, describe menopause. Interviews were conducted with 185 pre-, peri-, and post-menopausal women aged 45 to 55. We found that pre-menopausal women felt anxious compared with peri- and post-menopausal women's more affirmative attitudes of increasing confidence and freedom in this new cycle of life. A dominant theme was the constr…
Prevalence and determinants of headaches in Hawaii
Standardized measures of daily hassles, life and job satisfaction were not associated with headaches. The relationship between headaches and having young children suggests that the everyday stress of family life is a headache risk. This may be particularly true in Hilo, Hawaii, where the value of family is culturally prioritized
Relationship Between Hot Flashes and Ambulatory Blood Pressure
OBJECTIVES: To examine ambulatory blood pressure (BP) differences between women who report hot flashes (HFs) and those who do not, and to observe whether an objectively measured HF is associated with transient changes in BP. HFs have been associated with elevated BP, but studies have not examined the relationship between objectively measured HFs and blood pressure during normal daily activities. METHODS: A sample of 202 women in Hilo, Hawaii, age…
Measures of adiposity in two cohorts of Hawaiian school children
Ethnic disparity in adiposity among Native Hawaiians compared with non-Hawaiian age mates occurs after the age of 6 years, and is confined to males in this sample. For older girls, father's, but not mother's, educational attainment was inversely related to adiposity
Relation between C‐reactive protein levels and body composition in a multiethnic sample of school children in Hawaii
OBJECTIVES: Adipose cells secrete proinflammatory cytokines that stimulate hepatic production of C-reactive protein (CRP). CRP levels are associated with adiposity levels in adults, adolescents, and older children but not in young children (age 2-3). This study examined the relation between CRP, adiposity, and cardiovascular and metabolic variables including blood pressure, glucose, and blood lipids in two young cohorts of children, averaging app…
Effects of ethnicity and socioeconomic status on body composition in an admixed, multiethnic population in Hawaii
This study determined ethnic differences in anthropometric measures of a sample of adults in Hawaii, examining the effects of differing degrees of ethnic admixing and socioeconomic status (SES) on the measures. Adults who had attended elementary school in Hawaii underwent anthropometric measurements and answered questionnaires about their educational attainment, income, age, cultural identity, ethnic ancestry, and health. Individuals reporting As…
Exhaled nitric oxide decreases upon acute exposure to high-altitude hypoxia
Nitric oxide (NO) is a vasodilator that plays a role in blood flow and oxygen delivery. Acute hypoxia down regulates NO synthesis, a response that may exacerbate hypoxic stress by decreasing blood flow. This study was designed to test the hypotheses that pulmonary NO decreases upon acute exposure to high-altitude hypoxia and that relatively low levels of NO at altitude are associated with greater stress as reflected in more symptoms of acute moun…
Occupational Differences in Job Strain and Physiological Stress
OBJECTIVES: The two objectives are to test the hypothesis that women in a profession with low decision latitude will have greater catecholamine excretion and higher blood pressure than women in a profession with greater decision latitude, and to assess the influence of ethnicity on the occupational comparison. METHODS: Premenopausal women who were either full-time teachers in public schools (teachers; N = 92) or nurses or nurse's aides (nurses; N…
Effects of age, ethnicity and menopause on ambulatory blood pressure
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…
Physiological Stress Responses in Filipino-American Immigrant Nurses
OBJECTIVE: The purpose of this study was to evaluate the relationship between measures of Americanization (the adoption of American life-style and culture) and physiological measures of stress in Filipino-American immigrants. METHODS: Ambulatory blood pressure monitors and timed urine collections were used to evaluate blood pressure and urinary catecholamine excretion across the work, home, and sleep daily settings among 31 healthy, premenopausal…
Comparison of factors affecting daily variation of blood pressure in Filipino-American and Caucasian nurses in Hawaii
Although several studies have examined differences in daily blood pressure variability between African-American and Caucasian groups in the United States, little is known about the blood pressure variation of other ethnic groups. This study examined the effects of emotional state, setting, posture, and ethnicity on the ambulatory blood pressure of female health care workers (nurses and nurse's aides) from 2 ethnic groups: Filipino-Americans (N = …
The Biological Stress Response and Lifestyle
Many measures in human biology that are studied as immutable traits are actually fluctuating physiological functions that adjust body systems to rapid changes in the environment. This overview discusses what has been learned about the response to the stressors inherent in continuously changing microenvironments in modern Western societies of two related physiological functions: the release of catecholamines and blood pressure. The review shows th…

Menarche age, fatness, and fat distribution in Hawaiian adolescents
Menarche age was assessed in 93 adolescent females in a sample of public schools in East Hawaii. Native Hawaiian girls had significantly lower reported age at menarche than non-Hawaiian classmates. Age at menarche was significantly correlated with total fatness as measured by the sum of six skinfolds in girls who had reached menarche at least 2 years previous to measurement. When fatness was controlled in comparisons, the ethnic differences were …
Relation of subcutaneous fat distribution to percentage of Polynesian ancestry in native Hawaiian children
A semilongitudinal study of the growth of Hawaiian children from four cohorts was carried out with measurements taken at four consecutive annual visits. Each visit entailed an anthropometric battery, including skinfold measurements at six sites. Additionally, interviews with children and their families elicited information on socioeconomic status, other social conditions, and degree of identification with Hawaiian culture. Genealogies were comple…
Stress and changing lifestyles in the Pacific
The lifestyles and social environments of Pacific Islanders have changed profoundly as a result of local development and migration to urban, cosmopolitan centers. These changes have often been accompanied by an increase in chronic diseases, alcoholism, and suicide. As a result, the health effects of psychological and physiological stress have become an increasing concern in Pacific Island nations and in countries with significant Pacific migrant …
General Stress in Anthropological Fieldwork
Human stress reactions are responses to physical, biotic, and sociocultural stimuli that lead to appraisal of the need for adaptive activity. Commonly used measures of stress in anthropology, such as questionnaires, are subjective in nature and inappropriate for cross-cultural comparisons. Physiological measures of stress, such as urinary levels of catecholamines and corticosteroids, are applicable for these comparisons and may have wide utility …

Physiological stress and culture change in a group of Filipino-Americans
This preliminary survey evaluates the utility of physiological measures of general stress in anthropological fieldwork. The survey was conducted in a community of Filipino-Americans whose residents share similar housing conditions and low income levels but vary in ethnicity, migration status and degree of contact with Hawaii's urban culture. General stress levels are evaluated both by a subjective stress measure--the Cornell Medical Index (CMI)--…
Acute mountain sickness and physiological stress during intermittent exposure to high altitude
The effect of intermittent exposure to high altitude (4200 m) hypoxia on symptomatology of acute mountain sickness (AMS) was observed, and the relationship between AMS and stress hormone excretion was examined among shift workers at the United Kingdom Infrared Telescope (UKIRT) facility and a control group of sea level residents. Some of the shift workers experienced AMS during their first day at altitude, but had recovered after 5 days residence…
Growth of native Hawaiian school children
A semilongitudinal survey of the growth of native Hawaiian school children, focused on the development of fatness, has been carried out on the Island of Hawaii. Four cohorts of children, first studied in grades one, four, seven, and ten, were measured annually for four years. Several factors, including percentage of Polynesian ancestry, identification with Hawaiian culture, socioeconomic status, dietary intake, and physical fitness, have been con…
Growth of native Hawaiian school children
Annual measurements of skinfold thicknesses at six sites (triceps, biceps, medial calf, subscapular, abdominal, and suprailiac) and the body mass index have been obtained from a sample of native Hawaiian school children and their non‐Hawaiian classmates in a four year semilongitudinal study. Four cohorts were measured, with the children beginning the study in grades one, four, seven and ten, respectively. Information on percentage of Polynesian a…
