Performance of the U.S. Office of Management and Budget's Revised Race and Ethnicity Categories in Asian Populations*.

OBJECTIVES: The U.S. Office of Management and Budget (OMB) guidelines for collecting and reporting race and ethnicity information recently divided the "Asian or Pacific Islander" category into "Asian" and "Native Hawaiian or Other Pacific Islander".

Serum ferritin and transferrin saturation in Asians and Pacific Islanders.

Background: Asians and Pacific Islanders in the Hemochromatosis and Iron Overload Screening (HEIRS) Study had the highest prevalence of elevated serum ferritin (SF) and transferrin saturation (TS) levels, but to our knowledge, the reasons for this have not been investigated.

Methods: Using multiple linear regression, we compared TS and SF distributions for 42 720 Asian, Pacific Islander, and white HEIRS Study participants recruited through 5 field centers in North America who did not have HFE C282Y or H63D alleles.

Results: Compared with their white counterparts, Asian men had a 69-ng/mL (155-pmol/L) higher adjusted mean SF level and a 3% higher TS level (P<.

Geographic and racial/ethnic differences in HFE mutation frequencies in the Hemochromatosis and Iron Overload Screening (HEIRS) Study.

Objective: To assess geographic differences in the frequencies of HFE C282Y and H63D genotypes in six racial/ethnic groups recruited in the Hemochromatosis and Iron Overload Screening (HEIRS) Study.

Design: HFE C282Y and H63D genotypes of 97,551 participants, ages > or = 25 years, who reported that they belonged to one of six racial/ethnic groups, were analyzed. HFE genotype frequencies were compared among the racial/ethnic groups and among the HEIRS Study field centers within each racial/ethnic group.

Hemochromatosis and iron-overload screening in a racially diverse population.

Background: Iron overload and hemochromatosis are common, treatable conditions. HFE genotypes, levels of serum ferritin, transferrin saturation values, and self-reported medical history were studied in a multiethnic primary care population.

Methods: Participants were recruited from primary care practices and blood-drawing laboratories.

Psychosocial and cultural factors affecting the perceived risk of genetically modified food: an overview of the literature.

The rapid globalization of the world economy has increased the need for an astute understanding of cultural differences in perceptions, values, and ways of thinking about new food technologies. In this paper, we describe how socio-psychological and cultural factors may affect public perceptions of the risk of genetically modified (GM) food. We present psychological, sociological, and anthropological research on risk perception as a framework for understanding cross-national differences in reactions to GM food.

Ethnic differences in quality of life among early breast and prostate cancer survivors.

This study assessed quality of life (QOL) in recently diagnosed breast and prostate cancer patients of European American and Asian Pacific Islanders (specifically, individuals of Filipino, Japanese, and Native Hawaiian ancestry) to investigate whether QOL varied according to ethnicity and the relative importance of ethnicity as a predictor of QOL. Participants were identified through consecutive registrations on the Hawaii Tumor Registry, based on a diagnosis of breast or prostate cancer 4-6 months previously. QOL was measured by the QLQ-C30, a standardized questionnaire widely used in cancer patient populations.
