Association of diabetes and cancer mortality in American Indians: the Strong Heart Study.

Purpose: The metabolic abnormalities that accompany diabetes mellitus are associated with an increased risk of many cancers. These associations, however, have not been well studied in American Indian populations, which experience a high prevalence of diabetes. The Strong Heart Study is a population-based, prospective cohort study with extensive characterization of diabetes status.

Acute myocardial infarction quality of care: the Strong Heart Study.

Objectives: Evaluate the quality of care provided patients with acute myocardial infarction and compare with similar national and regional data.

Design: Case series.

Setting: The Strong Heart Study has extensive population-based data related to cardiovascular events among American Indians living in three rural regions of the United States.

Physical activity levels in American-Indian adults: the Strong Heart Family Study.

Background: A limited body of evidence, mostly based on self-report, is available regarding physical activity levels among American-Indian adults.

Purpose: This study aims to examine physical activity levels objectively using pedometers among a large cohort of American-Indian adult participants in the Strong Heart Family Study (SHFS).

Methods: Physical activity levels in 2604 American-Indian adults, aged 18-91 years, from 13 American-Indian communities were assessed using Accusplit AE120 pedometers over a period of 7 days during 2001-2003.

Subjective and objective sleep quality and aging in the sleep heart health study.

Objectives: To examine the extent to which subjective and objective sleep quality are related to age independent of chronic health conditions.

Design: Cross-sectional study.

Setting: The Sleep Heart Health Study (SHHS) is a multicenter study designed to determine the cardiovascular consequences and the natural history of sleep disordered breathing.

Different factor loadings for SF36: the Strong Heart Study and the National Survey of Functional Health Status.

Background: To increase our understanding of the psychometric characteristics and factor structure of the SF36 in older American Indian populations.

Methods: Between 1993 and 1995, SF36 data were collected from 3,488 Phase II participants of the Strong Heart Study (SHS) between the ages of 48 and 81. Comparison data were provided by an age- and gender-matched sample (n = 695) from the National Survey of Functional Health Status (NSFHS) conducted in 1989 and 1990.

Cardiovascular disease and risk factors in three Alaskan Eskimo populations: the Alaska-Siberia project.

Objectives: To determine the prevalence of CVD and to identify and characterize associated risk factors in three distinct Eskimo populations.

Study Design: Cross-sectional.

Methods: A slightly modified Strong Heart Study protocol was followed to examine 454 participants, aged 25-91, from four villages.

C-reactive protein as a predictor of cardiovascular risk in a population with a high prevalence of diabetes: the Strong Heart Study.

Background: High-sensitivity C-reactive protein (CRP) has been investigated extensively as a marker for predicting the risk of cardiovascular disease (CVD). CVD accounts for a large proportion of mortality and morbidity in American Indians; we sought to test the association of CRP and CVD in a population-based American Indian cohort 45 to 74 years old.

Methods And Results: Of 3277 participants who were CVD-free at baseline, 542 had CRP >10 mg/L and were excluded from analysis; 50.
