Quantifying cancer risk from exposures to medical imaging in the Risk of Pediatric and Adolescent Cancer Associated with Medical Imaging (RIC) Study: research methods and cohort profile.

Purpose: The Risk of Pediatric and Adolescent Cancer Associated with Medical Imaging (RIC) Study is quantifying the association between cumulative radiation exposure from fetal and/or childhood medical imaging and subsequent cancer risk. This manuscript describes the study cohorts and research methods.

Methods: The RIC Study is a longitudinal study of children in two retrospective cohorts from 6 U.

Prevalence of diabetes and glucose intolerance in an ethnically diverse rural community of Hawaii.

Background: We report the prevalence of diabetes in a rural, multiethnic community in Hawaii, of predominantly Asian and Native Hawaiian ancestry, by using 1997 World Health Organization diagnostic criteria applied to a two-hour oral glucose tolerance test.

Methods: This cross-sectional survey included 1452 men and nonpregnant women who were >18 years of age. Blood was drawn in the fasting and postchallenge states.

Association between angiotensin-converting enzyme gene polymorphisms and QT duration in a multiethnic population in Hawaii.

Objectives: Recent studies have suggested that heart-rate corrected QT interval (QTc) in normal populations may be influenced by genetic factors. We report findings of a study of the relationship between QTc, increased QTc (> 440 ms) and angiotensin-converting enzyme (ACE) genotype in a multiethnic, population-based study completed in rural Hawaii.

Methods: Blood samples were obtained while fasting and after an oral glucose challenge from 1452 individuals between 1997 and 2000.

Native Hawaiian Birth Weight and Infant Mortality: Is Birth in Hawai'i Protective?

PURPOSE OF THE PAPER: This study provides baseline information on the characteristics of Native Hawaiian mothers and the health status of their infants, comparing residents of Hawaii with those of the continental U.S. The impact of Hawaii residence on low birth weight and infant mortality among Native Hawaiians is assessed.

Pregnancy outcomes among Whites and Filipinos: A paradoxical birth weight-neonatal mortality relationship.

Evidence from the Philippines suggests that, compared to Whites, infants born to Filipino women are more likely to be low birth weight. A paucity of information is available regarding birth outcomes of U.S.
