Physical Activity Among Native Hawaiians and Pacific Islanders: A Systematic Review and Meta-Analysis

Objective

To examine the proportion of Native Hawaiian and Pacific Islander (NHPI) meeting recommended physical activity guidelines for Americans (PAG) and determine differences in physical activity (PA) by sex and between NHPI and Asians when data are disaggregated.

Health Indicators of Native Hawaiian and Pacific Islanders in the United States

This study aimed to describe health indicators and behaviors of Native Hawaiian and Pacific Islander (NHPI) adults and to compare findings to previous reports on US NHPI and the US population. A sample of N = 100 (56 M, 44 F) NHPI adults aged 40–59 years completed an anonymous questionnaire addressing education and household income, tobacco use, physical activity, fruit and vegetable (F&V) consumption, cancer screening and health status. Objective measures of height and weight were taken to calculate body mass index (BMI). The study sample consisted of 49% current smokers and the majority was not meeting guidelines for physical activity (80%) or F&V consumption (99%). Cancer screening rates ranged from 0 to 57% and were higher among females. Mean BMI was 33.9 ± 7.5 kg/m² and 95% were overweight or obese. While 36.7% were hypertensive, only 11.1% were taking prescribed medication. Compared to both the general US population and available data for US NHPI, study participants reported higher prevalence of obesity and chronic conditions (hypertension, high cholesterol, diabetes, and angina/CHD) and lower levels of physical activity, F&V consumption and cancer screening rates. Study findings contribute to the limited knowledge regarding health behaviors of US NHPI. Comparisons to US data increase evidence of NHPI health disparities, while comparisons to previous NHPI studies emphasize the magnitude of unhealthy lifestyle behaviors and subsequent adverse health conditions for this particular sample. Further improvements to community outreach and recruitment strategies could successfully encourage high-risk individuals to participate in health promotion and behavior intervention studies to improve NHPI health behaviors.

Favorable Outcomes for Native Hawaiians and Other Pacific Islanders with Severe Traumatic Brain Injury

Traumatic brain injury (TBI) disproportionately impacts minority racial groups. However, limited information exists on TBI outcomes among Native Hawaiians and other Pacific Islanders (NHPI). All patients with severe TBI (Glasgow Coma Scale (GCS) <9) who were hospitalized at the state-designated trauma center in Hawai‘i from March 2006 to February 2011 were studied. The primary outcome measure was discharge Glasgow Outcome Scale ([GOS]: 1, death; 2, vegetative state; 3, severe disability; 4, moderate disability; 5, good recovery), which was dichotomized to unfavorable (GOS 1–2) and favorable (GOS 3–5). Logistic regression analyses were performed to assess factors predictive of discharge functional outcome. A total of 181 patients with severe TBI (NHPI 27%, Asians 25%, Whites 30%, and others 17%) were studied. NHPI had a higher prevalence of assault-related TBI (25% vs 6.5%, P = .046), higher prevalence of chronic drug abuse (20% vs 4%, P = .02) and chronic alcohol abuse (22% vs 2%, P = .003), and longer intensive care unit length of stay (15±10 days vs 11±9 days, P < .05) compared to Asians. NHPI had lower prevalence of unfavorable functional outcomes compared to Asians (33% vs 61%, P = .006) and Whites (33% vs 56%, P = .02). Logistic regression analyses showed that Asian race (OR, 6.41; 95% CI, 1.68–24.50) and White race (OR, 4.32; 95% CI, 1.27–14.62) are independently associated with unfavorable outcome compared to NHPI. Contrary to the hypothesis, NHPI with severe TBI have better discharge functional outcomes compared to other major racial groups.     

AIDS among Asians and Pacific Islanders in the United States

OBJECTIVE: To characterize Asians and Pacific Islanders in the United States with reported acquired immunodeficiency syndrome (AIDS). METHODS: AIDS surveillance data reported through June 1998 were analyzed. Characteristics of cumulative case patients, rates of AIDS incidence in 1996 through 1997, and trends from 1982 through 1996 were analyzed. RESULTS: Through December 1998, 4,928 Asian and Pacific Islander adults and 46 Asian and Pacific Islander children with AIDS were reported in the United States. Of the total cases, 89% were in men, and 79% of those were in men who have sex with men (MSM). Five states, which account for 63% of the Asian and Pacific Islander population in the United States, reported 78% of the cases: California (45%), Hawaii (12%), New York (15%), Texas (3%), and Washington (3%). Of the 92% of Asian and Pacific Islander patients with country of birth information, 59% were foreign-born, a percentage that corresponds to the distribution in the general population. The overall incidence rate per 100,000 for 1996 through 1997 was 12.8 (21.3 for men; 3.3 for women). The highest rate was in the Northeast (15.9), followed by the West (13.8), South (10.6), and Midwest (5.7). Tuberculosis, reported for 6% of Asians and Pacific Islanders, was higher among foreign-born than among U.S.-born Asians and Pacific Islanders (8% and 4%, respectively). Between 1982 and 1996, AIDS incidence among MSM increased and peaked in 1994. Among heterosexual contacts and injection drug users, incidence has increased but remained low. CONCLUSIONS: The AIDS epidemic among Asians and Pacific Islanders in the United States has primarily affected MSM and is concentrated in a few states where most Asians and Pacific Islanders reside. Prevention activities should include consideration of cultural diversity and an understanding of cultural norms regarding sexuality. Additional information on risk behaviors and seroprevalence among Asian and Pacific Islander MSM is needed to better guide prevention planning.     

Challenges in Identifying Native Hawaiians and Pacific Islanders in Population-Based Cancer Registries in the U.S.

Lack of disaggregated data for Native Hawaiians and Pacific Islanders (NHPIs) in the U.S. has resulted in severe gaps in understanding health disparities and unique health needs of NHPIs. Telephone interviews were conducted with 272 cancer patients identified by a population-based cancer registry. The self-reported NHPIs status was compared with that identified by the registry. Sensitivity, Specificity, Positive Predictive Value (PPV), and Negative Predictive Value (NPV) were calculated. Alternative NHPIs identification methods were explored. The registry had acceptable sensitivity (89%), specificity (96%) and NPV (99%), but low PPV (62%) in identifying NHPIs. Using additional information on surname and birthplace from the registry improved the identification of NHPIs, but either increased the false positive or decreased the counts of true NHPIs cases. Improved data collection methods and practices in identifying NHPIs in population-based cancer registries are needed and caution in interpreting cancer data for NHPIs is warranted.     

Food Security Status of Native Hawaiians and Pacific Islanders in the US: Analysis of a National Survey

ObjectiveTo document food insecurity prevalence among a nationally representative sample of Native Hawaiian and Pacific Islander (NHPI) adults and compare differences in food security status across races/ethnicities in the US.MethodsUsing 2014 National Health Interview Survey and 2014 NHPI–National Health Interview Survey data, food insecurity among the NHPI population is described and food security status across racial/ethnic groups is compared using Rao-Scott chi-square and multinomial logistic regression.ResultsFood insecurity prevalence was 20.5% among NHPI adults, and NHPI had significantly higher odds of experiencing low and very low food security than white individuals. Food insecurity among Hispanic individuals, black people, and other races/ethnicities was also significantly higher than that among white people. Significant variation in food security status was observed by race/ethnicity (P < .001).Conclusions and ImplicationsThis study provides documentation of food insecurity prevalence among NHPI adults and will inform chronic disease and nutrition research and programs conducted with NHPI communities in the US.     

Physical activity and ethnic differences in hypertension prevalence in the United States

BACKGROUND: In the United States, non-Hispanic blacks have higher rates of hypertension than other ethnic groups. In addition, they have higher rates of physical inactivity, a behavior linked to high blood pressure. We examined associations between ethnicity, leisure-time physical activity (LTPA), and hypertension prevalence in a representative sample of U.S. adults. METHODS: Using data on 16,246 adults in the third National Health and Nutrition Examination Survey, hypertension prevalence was determined for non-Hispanic white, non-Hispanic black, and Mexican Americans at various levels of LTPA (none, 0.1-4.9 bouts/week at any intensity, 5+ bouts/week of moderate-to-vigorous activity). Logistic regression was used to examine relationships between hypertension prevalence, race, LTPA, and other variables. RESULTS: Hypertension prevalence was significantly less in the most active group, compared with their sedentary peers (odds ratio = 0.73, CI 0.59 to 0.90). Blacks had an odds ratio for hypertension of 1.77 (CI 1.49 to 2.10) compared with non-Hispanic whites, after adjusting for gender, age, income, LTPA, smoking, BMI, salt intake, rural/urban dwelling, and alcohol intake. Mexican Americans had an adjusted odds ratio of 0.75 (CI 0.62 to 0.89), relative to non-Hispanic whites. CONCLUSION: Ethnicity and LTPA are both associated with hypertension prevalence after controlling for each other, as well as other confounders. Thus, race and physical activity are important independent contributors to hypertension prevalence.     

Genetic research and the vulnerability of Native Hawaiians

Traditional research ethics are unable to provide adequate protections for human subjects involved in research--much less genetic research. New principles need to be developed to change the paradigm and put human research subjects in a more equitable relationship with their researchers. In addition, new laws should be crafted to level the playing field for human research participants. Humans can no longer look at themselves as hereditary beings, but as stewards of intra- and inter-generational genetic material in need of protection. Recommendations are provided.     

Physical activity and breast cancer risk among women in the southwestern United States

Physical activity may influence breast cancer risk through multiple mechanisms and at different periods in life. In this study we evaluate breast cancer risk associated with total and vigorous physical activity at ages 15, 30, and 50 years and the referent year prior to diagnosis/selection. Participants were non-Hispanic white (NHW) (1527 cases and 1601 control subjects) and Hispanic/American Indian (HAI) (798 cases and 924 controls) women. Both total and vigorous activity reduced risk of breast cancer in a dose-response manner. Among premenopausal women, only high total metabolic equivalent of the task (MET) hours of activity during the referent year was associated with reduced breast cancer risk in NHW women (odds ratio [OR] 0.62; 95% confidence interval [CI] 0.43, 0.91). Among postmenopausal women, physical activity had the greatest influence among women not recently exposed to hormones. Among these women, high total lifetime activity reduced risk of breast cancer for both NHW (OR 0.60; 95% CI 0.36, 1.02; p trend 0.01) and HAI women (OR 0.52; 95% CI 0.23, 1.16; p trend 0.07). Additionally, high total MET hours of activity at age 30 years (OR 0.56; 95% CI 0.37, 0.85) and at age 15 years (OR 0.57; 95% CI 0.38, 0.88) reduced breast cancer risk among postmenopausal NHW women not recently exposed to hormones. Among HAI women, more recent activity performed during the referent year and at age 50 appeared to have the greatest influence on breast cancer risk. Among postmenopausal NHW women. there was a significant interaction between physical activity and hormone replacement therapy (p value, 0.01), while among postmenopausal HAI women, physical activity interacted with body mass index (p value, 0.04). These data suggest that physical activity is important in reducing risk of breast cancer in both NHW and HAI women.     

Prenatal care among Puerto Ricans on the United States mainland

Recent public health initiatives in the USA identify the improvement of maternal and infant health outcomes among ethnic minorities as a national priority. Prenatal care is emphasized in these initiatives as a crucial intervention for reducing the risks of adverse outcomes. We investigate the barriers to prenatal care and the adequacy of prenatal care among mainland Puerto Ricans using data from a follow-back survey of a representative sample of mothers. The results show that barriers to prenatal care and the adequacy of prenatal care cannot be reduced solely to financial problems or problems associated with migration. Rather, attention to the social and the psychological circumstances surrounding the pregnancy (e.g. pregnancy wantedness) is required.     

Utilization of dental care services by Asians and native Hawaiian or other Pacific Islanders: United States, 1997-2000

OBJECTIVE: This report describes national estimates of dental care service utilization and unmet dental care needs due to cost for six Asian ethnic subgroups and the native Hawaiian or other Pacific Islander (NHOPI) population. METHODS: Combined data from the 1997-2000 National Health Interview Surveys (NHISs), conducted by the Centers for Disease Control's National Center for Health Statistics, were analyzed to produce estimates for Asians and NHOPIs aged 2 years and over. Information on dental care service utilization and unmet dental care needs due to cost was self-reported by persons aged 18 years and over. For children aged 2-17 years, the information was collected from an adult who was knowledgeable about the child's health. RESULTS: Approximately 64% of Asian and 56% NHOPI persons had visited a dentist at least once in the past year. Utilization of dental care services, however, varies significantly by ethnic subgroup. Asian Indians were most likely to have never had a dental visit and the NHOPIs were most likely to experience unmet dental care needs in the past year. Among adults, Japanese Americans (68.2%) were most likely and NHOPIs (49.3%) were least likely to have had a dental visit in the past year. Underutilization of dental care services was most prevalent among Asian adults with poor or near poor poverty status, without health insurance coverage, and who had resided in the United States for less than 5 years. Among children, NHOPIs (82.0%) were most likely and Asian Indians (60.1%) were least likely to have had a dental visit in the past year. Underutilization was most prevalent among Asian children who were not living with their parents or living with a single parent, who had no insurance coverage, who had poor or near poor poverty status, and whose parents had less than 12 years of education. CONCLUSIONS: Utilization of dental care services and unmet dental care needs due to cost vary among the Asian ethnic subgroups and the NHOPI population.
