Prevalence of hearing loss in Black and White elders: results of the Cardiovascular Health Study.

Purpose: The goal of this study was to determine the impact of age, gender, and race on the prevalence and severity of hearing loss in elder adults, aged 72-96 years, after accounting for income, education, smoking, and clinical and subclinical cardiovascular disease. Methods Air-conduction thresholds for standard and extended high-frequency pure-tones were obtained from a cohort of 548 (out of 717) elderly adults (ages 72-96 years) who were recruited during the Year 11 clinical visit (1999-2000) of the Cardiovascular Health Study (CHS) at the Pittsburgh, Pennsylvania site. Participant smoking, income, education, and cardiovascular disease histories were obtained from the CHS database and were included as factors.

The relationship between C-reactive protein and carotid intima-media wall thickness in middle-aged women with polycystic ovary syndrome.

Polycystic ovary syndrome (PCOS) is associated with premature carotid atherosclerosis. C-Reactive protein (CRP) has been implicated as a vascular disease risk factor. The objective of this study was to determine whether elevated CRP is associated with increased carotid intima-media wall thickness (IMT) in PCOS women.

Dietary intake, physical activity, and obesity in women with polycystic ovary syndrome.

Objective: To determine whether dietary intake and physical activity contribute to obesity in women with polycystic ovary syndrome (PCOS).

Design: Case-control study.

Subjects: A total of 84 cases and 79 neighborhood controls of similar age.

Long-term follow-up of the residents of the Three Mile Island accident area: 1979-1998.

The Three Mile Island (TMI) nuclear power plant accident (1979) prompted the Pennsylvania Department of Health to initiate a cohort mortality study in the TMI accident area. This study is significant because of the long follow-up (1979-1998), large cohort size (32,135), and evidence from earlier reports indicating increased cancer risks. Standardized mortality ratios (SMRs) were calculated to assess the mortality experience of the cohort compared with a local population.

Evidence for competing effects of body mass, hyperinsulinemia, insulin resistance, and androgens on leptin levels among lean, overweight, and obese women with polycystic ovary syndrome.

Objective: To evaluate the relationships between leptin, body composition, insulin resistance, androgens, and reproductive indices among women with polycystic ovary syndrome (PCOS).

Design: Matched case-control study.

Setting: Academic reproductive endocrine practice; school of public health.
