    PURPOSE: To examine the relationships between disordered eating, menstrual irregularity, and low bone mineral density (BMD) in young female runners.

    METHODS: Subjects were 91 competitive female distance runners aged 18-26 yr. Disordered eating was measured by the Eating Disorder Inventory (EDI). Menstrual irregularity was defined as oligo/amenorrhea (0-9 menses per year). BMD was measured by dual x-ray absorptiometry.

    RESULTS: An elevated score on the EDI (highest quartile) was ...

    BACKGROUND: By one estimate, 60% of women experiencing the menopause transition perceive that they have memory problems, but most studies that have used cognitive function tests have not substantiated a relation between menopause stage and cognitive performance. We sought to describe the cross-sectional relation between menopause status, estradiol (E(2)), follicle-stimulating hormone (FSH), and measured cognitive function.

    METHODS: Cross sectional analysis of a community-based cohort of ...

    BACKGROUND: There is almost no longitudinal information about measured cognitive performance during the menopause transition (MT).

    METHODS: We studied 2,362 participants from the Study of Women's Health Across the Nation for 4 years. Major exposures were time spent in MT stages, hormone use prior to the final menstrual period, and postmenopausal current hormone use. Outcomes were longitudinal performance in three domains: processing speed (Symbol Digit Modalities Test [SDMT]), verbal ...

    BACKGROUND: A long-held view links higher socioeconomic status (SES) to higher rates of childhood leukaemia. Some recent studies exhibit associations in the opposite direction.

    METHODS: We reviewed journal literature through August 2002 for associations between childhood leukaemia and socioeconomic measures. We determined the direction of each association and its P-value. We described the results with regard to study design, calendar period, geographic locale, and level of the ...

    Left-handedness has been associated with increased fracture risk in a small number of previous studies. This study reports risks for fractures at the proximal humerus, distal forearm, pelvis, foot, and shaft of the tibia/fibula according to handedness in a case-control study conducted from October 1996 to May 2001 among members of Northern California Kaiser Permanente. Handedness was assessed by questionnaire for 2,841 cases and 2,192 controls, and subjects were categorized as ...

    OBJECTIVE: To examine the relationship between food frequency questionnaire estimated isoflavone intakes and cognitive performance.

    DESIGN: The Study of Women's Health Across the Nation (SWAN), is a multiethnic, community based, longitudinal study of women aged 42 to 52 years at entry. Dietary isoflavone intakes were estimated from an interviewer-administered food frequency questionnaire at baseline. Intakes of genistein and daidzein were highly correlated (r = 0.98); therefore, analyses ...

    A case-control study undertaken among members of five Northern California Kaiser Permanente medical centers sought to identify risk factors for foot fractures among persons aged 45 years and older. Foot fracture cases (n=920) and frequency matched controls (n=2366) were interviewed between October 1996 and May 2001 using a standardized questionnaire. Foot fractures occurred most often while walking or climbing stairs. While 60% of foot fractures resulted from falls, 20% were attributed ...
