Cabbage and Sauerkraut Consumption in Adolescence and Adulthood and Breast Cancer Risk among US-Resident Polish Migrant Women.

Background: Breast cancer (BC) incidence and mortality are lower in Poland than in the United States (US). However, Polish-born migrant women to US approach the higher BC mortality rates of US women. We evaluated the association between consumption of cabbage/sauerkraut foods and BC risk in Polish-born migrants to US.

Objective: To assess the extent of error present in self-reported weight data in the Women's Health Initiative, variables that may be associated with error, and to develop methods to reduce any identified error.

Design: Prospective cohort study.

Setting: Forty clinical centres in the USA.

Racial and Ethnic Differences in Anthropometric Measures as Risk Factors for Diabetes.

Objective: The study objective was to examine the impact of race/ethnicity on associations between anthropometric measures and diabetes risk.

Research Design And Methods: A total of 136,112 postmenopausal women aged 50-79 years participating in the Women's Health Initiative without baseline cancer or diabetes were followed for 14.6 years.

Evolutionary Origins of the Differences in Osteoporosis Risk in US Populations.

Over the past 50 years, it has been increasingly evident that there are population differences in bone mass and the risk of osteoporosis. In the United States, many studies have reported a lower prevalence of osteoporosis in African Americans compared with people of European descent. If we trace the trajectory of changes in lifeways from the earliest migrations of early Homo out of Africa over the past two million years or so, to include lower vitamin D levels in higher latitudes; more meat in the diet; increasing sedentism; and a longer lifespan/longer postmenopausal period, it is not surprising that osteoporosis occurs more frequently in populations of European descent.

Hip geometry in diabetic women: implications for fracture risk.

Objective: Women with type 2 diabetes mellitus (T2DM) have a higher risk of fractures despite increased bone mineral density (BMD) as compared to women without diabetes. We hypothesized that bone strength is diminished in women with T2DM after accounting for lean body mass, which may contribute to their increased fracture risk.

Methods: Participants from Women's Health Initiative Observational Study were included in this cross-sectional study.

Longitudinal study of depot medroxyprogesterone acetate (Depo-Provera) effects on bone health in adolescents: study design, population characteristics and baseline bone mineral density.

Background: This analysis was conducted to assess the baseline data and design methodology within an observational longitudinal comparison of use vs. nonuse of the injectable (intramuscular) contraceptive depot medroxyprogesterone acetate (DMPA-IM) and its effect on bone mass in adolescent women.

Study Design: A prospective, observational, open-label, unmatched-cohort, safety study in females aged 11-18 years.

The relationship of physical activity and percentage of body fat to the risk of asthma in 8- to 10-year-old children.

To evaluate physical activity, obesity and asthma, we analyzed information from children attending a racially diverse middle-class suburban school district. Physical activity in metabolic equivalents (METS) and percent body fat were related to diagnosed asthma. On average the, 636 children were 8.

Comparisons of body size, composition, and whole body bone mass between North American and South African children.

Unlabelled: We compared whole body BMC of 811 black, white, and mixed ancestral origin children from Detroit, MI; Johannesburg, South Africa; and Cape Town, South Africa. Our findings support the role of genetic and environmental influences in the determination of bone mass in prepubertal children.

Introduction: Higher bone mass and lower fracture rates have been shown in black compared with white children and adults in North America.

Bone mineral density in postmenarchal adolescent girls in the United States: associated biopsychosocial variables and bone turnover markers.

Purpose: During adolescence, bone formation prevails over resorption, resulting in accumulation of 40% of peak bone mass throughout this time period. Although multiple studies have explored bone mass accrual during the early stages of puberty, less is known about factors that may influence bone accrual during later years of adolescence. In the present cross-sectional study we examined relationships among bone mineral density (BMD) and demographic factors, behavioral variables, and bone metabolism markers in postmenarchal adolescent girls.

Genetic determinants of bone mass do not relate with breast cancer risk in US white and African-American women.

Introduction: The association between high bone mass and increased breast cancer risk has been established. Identification of polymorphisms and the resultant variant receptors suggests the possibility of differential effects on hormone responsive genes when complexed with the hormones. Both estrogen receptor-alpha (ER) and vitamin D receptor (VDR) polymorphisms have been associated with bone density.

Sex and ethnic differences in bone architecture.

Technologic developments and applications such as dual energy x-ray absorptiometry, magnetic resonance imaging, and computed tomography have enabled researchers to assess bone quantity (ie, bone mineral density) and bone quality (ie, bone architecture), which are two important and independent contributions to bone strength. Recent studies on sex differences in bone architecture indicate that a number of biomechanical variables lead to increased bone strength in males compared with females. Ethnic differences in bone architecture are less clear-cut, indicating a need to identify and test the social and biologic variables that race and ethnicity represent.

The relationship between blood leptin level and bone density is specific to ethnicity and menopausal status.

Leptin, the obesity hormone, has been linked to bone mineralization and tumorigenesis. In addition, both bone mineral density (BMD) and postmenopausal breast cancer are associated with obesity, but the interrelationships between obesity, leptin, BMD, and breast cancer are not yet clear. In particular, there is little published research comparing white and black women in terms of these variables.

Dissociation and posttraumatic stress 1 year after the World Trade Center disaster: follow-up of a longitudinal survey.

Background: We conducted a 1-year follow-up of an original mail survey of early reactions to the World Trade Center disaster.

Method: Of the 75 subjects originally surveyed, 58 (77%) responded. The survey included measures of dissociation (Dissociative Experiences Scale, Cambridge Depersonalization Scale, Clinician-Administered Dissociative States Scale), post-traumatic stress (Impact of Event Scale-Revised), social support (Interpersonal Support Evaluation List-short form), and a life quality measure (Quality of Life Enjoyment and Satisfaction Questionnaire-short form).

Comparison of cross-sectional geometry of the proximal femur in white and black women from Detroit and Johannesburg.

Unlabelled: There are known black-white differences in bone density measured by DXA but less is known about bone architecture. We compared cross-sectional geometric properties of the proximal femur in U.S.

Relationship of personality to dissociation and childhood trauma in borderline personality disorder.

Background: Dissociation is a prominent feature in some individuals with borderline personality disorder (BPD), yet our understanding of the meanings and implications of prominent dissociation in BPD remains limited. The purpose of this study was to investigate the relationship between dissociation and childhood trauma in BPD and to explore the relationships of dissociation and trauma to various personality features of BPD.

Methods: Twenty BPD subjects and 24 healthy comparison subjects of similar age and gender were administered the Dissociative Experiences Scale, the Childhood Trauma Questionnaire-short form, the Tridimensional Personality Questionnaire, the Defense Style Questionnaire, the Relationship Style Questionnaire, and the Schema Questionnaire.

Feeling unreal: a depersonalization disorder update of 117 cases.

Background: Despite a surge of interest and literature on depersonalization disorder in recent years, a large series of individuals with the disorder has not been described to date. In this report, we systematically elucidate the phenomenology, precipitants, antecedents, comorbidity, and treatment history in such a series.

Method: 117 adult subjects with depersonalization disorder (DSM-III-R/DSM-IV criteria) consecutively recruited to a number of depersonalization disorder research studies were administered structured and semistructured diagnostic interviews and the Dissociative Experiences Scale.

Examination of the pathological dissociation taxon in depersonalization disorder.

In recent years, the pathologic dissociation taxon developed by Waller, Putnam, and Carlson (Psychological Methods 1:300-321, 1996) from a Dissociative Identity Disorder (DID) sample has been increasingly used in studies of dissociation in general. However, the taxon's convergence with dissociative diagnoses other than DID, as well as the taxon's central premise that pathologic dissociation is a categorical rather than a dimensional construct, remain areas of exploration. This report examines the applicability of the pathologic dissociation taxon to Depersonalization Disorder (DPD).

Trabecular and integral bone density in adults with sickle cell disease.

Sickle cell disease (SCD) is a hereditary disorder of hemoglobin synthesis that can affect the skeletal system owing to accelerated hematopoiesis and/or bone infarction. Additionally, several studies have suggested that a low bone mass is associated with SCD, partly because of adverse effects on growth and development. The few previous studies of bone mineral density (BMD) in these patients have utilized dual-photon or dual-energy x-ray absorptiometric (DXA) techniques, which may have limited value in this population because it cannot correct for differences in bone size.

Radiographic measurements, bone mineral density, and the Singh Index in the proximal femur of white and black postmenopausal women.

Background: Radiographic measurements, bone mineral density (BMD), and the Singh Index were examined to assess ethnic differences in the architecture and trabecular patterns in the proximal femur.

Methods: We measured height (cm), weight (kg), and the following radiographic variables in 326 white and black postmenopausal women participating in the Women's Health Initiative at the Clinical Center in Detroit, MI: neck breadth, inferior neck cortical thickness, head diameter, subtrochanteric breadth, and subtrochanteric medial and lateral cortical thicknesses. Bone densitometry was performed by dual-energy x-ray absorptiometry (Hologic QDR 1000 plus; Hologic Inc, Bedford, MA) at 5 regional sites in the proximal femur.
