Objective: To determine the prevalence and barriers to human papillomavirus (HPV) vaccine uptake among 11-18 year olds in the Hawai'i's four major ethnic groups-Native Hawaiians, Filipinos, Japanese, and Caucasians. Study design: A telephone survey assessed parents' knowledge of HPV and the HPV vaccine, status of their child's HPV vaccine uptake, variables operationalizing the Health Belief Model, and barriers and motivators to uptake. Results: Across the groups, 799 parents completed the survey. About 35% of daughters and 19% of sons had received all three shots. Although ethnic differences in vaccine uptake were seen in bivariate analysis (with significantly lower uptake in Filipino youth), in multivariable logistic regression analysis, only Caucasian parents were significantly less likely to start their sons on the HPV vaccine series compared with Japanese parents (reference group). Having heard about the vaccine, believing in its effectiveness, and older age of the child were also associated with vaccine uptake. Motivators for HPV vaccination were physician's recommendation and wanting to protect one's child. The primary barrier to uptake was lack of knowledge about the vaccine. Conclusions: Findings reinforce the fact that a physician's recommendation and receipt of information about the vaccine are strong motivators for parents to vaccinate their children, regardless of ethnicity.

Data on dementia in Native Hawaiians and many Asian subgroups in the United States are limited. Inpatients with dementia have higher costs, longer stays, and higher mortality than those without dementia. This study compared rates of inpatients with a dementia diagnosis for disaggregated Asian and Pacific Islanders (Native Hawaiian, Chinese, Japanese, Filipino) with those of whites according to age (18-59, 60-69, 70-79, 80-89, ≤90) for all adults hospitalized in Hawai'i between December 2006 and December 2010; 13,465 inpatients with a dementia diagnosis were identified using International Classification of Diseases, Ninth Revision, codes. Rates were calculated using population size denominators derived from the U.S. Census. In all age categories, Native Hawaiians had the highest unadjusted rates of inpatients with dementia and were more likely to have a dementia diagnosis at discharge at younger ages than other racial and ethnic groups. In adjusted models (controlling for sex, residence location, and insurer), Native Hawaiian inpatients aged 18 to 59 (aRR = 1.50, 95% CI = 0.84-2.69), 60 to 69 (aRR = 2.53, 95% CI = 1.74-3.68), 70 to 79 (aRR = 2.19, 95% CI = 1.78-2.69), and 80 to 89 (aRR = 2.53, 95% CI = 1.24-1.71) were significantly more likely to have dementia than whites, as were Japanese aged 70 to 79 (aRR = 1.30, 95% CI = 1.01-1.67), 80 to 89 (aRR = 1.29, 95% CI = 1.05-1.57), and 90 and older (aRR = 1.51, 95% CI = 1.24-1.85). Japanese aged 18 to 59 had were significantly less likely to have dementia than whites (aRR = 0.40, 95% CI = 0.17-0.94). These patterns have important public health and clinical care implications for Native Hawaiians and older Japanese populations. Future studies should consider whether preventable medical risk, caregiving, socioeconomic conditions, genetic disposition, or a combination of these factors are responsible for these findings., (© 2014, Copyright the Authors Journal compilation © 2014, The American Geriatrics Society.)

Elderly (65+) Native Hawaiian, Filipino, and Japanese men and Filipino women have a higher risk of diabetes-related potentially preventable hospitalizations than Whites even when demographic factors and the higher diabetes prevalence in these populations is considered. The study objective was to determine if similar disparities are seen among the non-elderly (< 65). We used discharge data for all non-maternity hospitalizations by working-age adults (18-64 years) in Hawai'i from December 2006 to December 2010. Annual diabetes-related preventable hospitalization rates (by population diabetes prevalence) were compared by race/ethnicity (Japanese, Chinese, Native Hawaiian, Filipino, and White) and gender. Adjusted rate ratios (aRR) were calculated relative to Whites using multivariable models controlling for insurer, comorbidity, residence location, and age. After adjusting for ethnic-specific prevalence of diabetes and demographic factors, preventable hospitalizations rates were significantly higher for Native Hawaiians males (aRR:1.48; 95%CI:1.08-2.05) compared to Whites, but significantly lower for Chinese men (aRR:0.43;95%CI:0.30-0.61) and women (aRR:0.18;95%CI: 0.08-0.37), Japanese men (aRR:0.33;95%CI: 0.25-0.44) and women (aRR:0.34; 95%CI:0.23-0.51), and Filipino men (aRR:0.35;95%CI:0.28-0.43) and women (aRR:0.47;95%CI: 0.36-0.62). Rates for Native Hawaiian females did not differ significantly from Whites. Disparities in diabetes-related preventable hospitalizations were seen for working-age (18-64) Native Hawaiian men even when their higher population-level diabetes prevalence was considered. Further research is needed to determine factors affecting these disparities and to develop targeted interventions to reduce them. Significantly lower preventable hospitalization rates were seen among Asian groups compared to Whites. A better understanding of these findings may provide guidance for improving rates among Asian elderly as well as other non-elderly groups with disparities.

To identify the disease locus of familial hypertrophic cardiomyopathy (FHC) in a Chinese family, a genetic linkage study was performed using polymorphisms from various chromosomal regions. This family has eight affected members, including a case with typical features of apical hypertrophic cardiomyopathy of the Japanese type. The results revealed significant evidence of linkage of polymorphisms on chromosome 11p13-q13 and FHC in this family with a maximal lod score of 3.38 at theta = 0.00. Our data suggest that the locus responsible for FHC in this family maps to chromosome 11 and that the molecular basis of FHC in the case of apical hypertrophic cardiomyopathy of the Japanese type might be similar to that of other affected members in the same family. Further studies are needed to elucidate the whole spectrum of the genetic basis of apical hypertrophic cardiomyopathy of the Japanese type.

A retrospective analysis was performed in 926 consecutive Chinese persons, aged 14 to 68 years, in whom congenital heart disease had been diagnosed and catheterization had been performed over the past 24 years. The incidence of various congenital cardiac malformations was compared with that in other series reported world-wide. About 60% of the 926 patients underwent surgery, and anatomic details of the malformations were examined. Congenital aortic valvular stenosis and coarctation of the aorta were uncommon (2.4% and 1.2%, respectively) among the Chinese adults, and the ethnic differences with Western countries in the incidence of these 2 defects were apparent and real. In contrast, aneurysm of the sinus of Valsalva, either ruptured or nonruptured, was more common (4.3%) and the incidence of outlet muscular type (or type 1) of ventricular septal defect was 4 to 9 times as common as has been reported in the West. Genetic differences rather than environmental factors or dietary habits may explain these special features.
