Description of Variation in Age of Onset of Functional Limitations of Native Hawaiian and Pacific Islanders Compared to Other Racial and Ethnic Groups

Analysis of eligibility criteria in Alzheimer's and related dementias clinical trials

Overly restrictive clinical trial eligibility criteria can reduce generalizability, slow enrollment, and disproportionately exclude historically underrepresented populations. The eligibility criteria for 196 Alzheimer's Disease and Related Dementias (AD/ADRD) trials funded by the National Institute on Aging were analyzed to identify common criteria and their potential to disproportionately exclude participants by race/ethnicity. The trials were categorized by type (48 Phase I/II pharmacological, 7 Phase III/IV pharmacological, 128 non-pharmacological, 7 diagnostic, and 6 neuropsychiatric) and target population (51 AD/ADRD, 58 Mild Cognitive Impairment, 25 at-risk, and 62 cognitively normal). Eligibility criteria were coded into the following categories: Medical, Neurologic, Psychiatric, and Procedural. A literature search was conducted to describe the prevalence of disparities for eligibility criteria for African Americans/Black (AA/B), Hispanic/Latino (H/L), American Indian/Alaska Native (AI/AN) and Native Hawaiian/Pacific Islander (NH/PI) populations. The trials had a median of 15 criteria. The most frequent criterion were age cutoffs (87% of trials), specified neurologic (65%), and psychiatric disorders (61%). Underrepresented groups could be disproportionately excluded by 16 eligibility categories; 42% of trials specified English-speakers only in their criteria. Most trials (82%) contain poorly operationalized criteria (i.e., criteria not well defined that can have multiple interpretations/means of implementation) and criteria that may reduce racial/ethnic enrollment diversity.

Association Between Physical Activity and Physical Function in a Marshallese Population with Type 2 Diabetes

Physical activity can delay functional decline in people with type 2 diabetes (T2D), but these associations have not been studied within a sample of Native Hawaiian or Pacific Islander adults with T2D. Using data from a randomized control trial in which 218 Marshallese adults with T2D participated in a 10-week diabetes self-management education intervention, this study tested our hypothesis that physical activity would predict physical function when controlling for time and other variables. Levels of physical activity were positively associated with levels of physical function, even after controlling for time and other covariates. These findings provide a more robust understanding of the relationship between physical activity and physical function in a sample of minority adults with T2D. Future studies should further explore levels of physical activity needed to maintain and improve physical function so that culturally appropriate physical activity interventions can be developed.

Daily Moderate-to-Vigorous Activity of Native Hawaiians and Pacific Islanders and Seven Asian Subgroups by Types of Activities, American Time Use Survey, 2010-2019

The study used the American Time Use Survey data from 2010 to 2019 to compare the daily moderate-to-vigorous activity of Native Hawaiians and Pacific Islanders (NHPI) and seven Asian ethnic subgroups. Adults aged 24 years and older were included. The study analyzed activities from sports and recreation, household activities, and all activities carried out during the day. Outcomes were determined by the completion of 30 min or more of moderate-to-vigorous activity and the type of activity carried out in the day. Significant ethnic differences were observed for sports and recreation but not for household activities and not for all activities carried out during the day. Of the ethnic populations, NHPI were the least active, and Asian Indians and Chinese were the most active. A majority achieved 30 min or more of moderate-to-vigorous activity during the day from all their activities. Physical activity from household activities exceeded physical activity from sports and recreation. The most physically active group was adults over the age of 65 years, perhaps reflecting more time to exercise or greater concerns about their health. For sports and recreation, exercising with someone doubled the minutes of moderate-to-vigorous activity. The results emphasize the importance of activities performed around the household in addition to sports and recreation and the benefit of exercising with someone. Ethnic populations may be receptive to interventions that emphasize activities they are performing in their daily lives.

Associations between physical activity and functional limitations in Native Hawaiian and Pacific Islander middle-aged and older adults in the United States

OBJECTIVES

Physical activity (PA) can help individuals maintain physical function and independence. The association between PA and functional limitations (FL) has not been explored in the Native Hawaiian and Pacific Islander (NHPI) population. The purpose of this study was to examine relationships between PA and FL among NHPI adults (age ≥ 45 years) living in the United States.

DESIGN

Cross-sectional data from the 2014 NHPI-National Health Interview Survey (N = 628) was used to create three constructs of FL based on responses from the Functioning and Disability Survey Module: needing equipment/assistance, having difficulty walking, and having difficulty with performing self-care and other fine motor activities. We used 2-stage least squares regression to examine the relationship between PA and FL of NHPI adults while accounting for the potential endogeneity of PA to FL.

RESULTS

Compared to NHPI adults who met the guideline for recommended levels of aerobic and strengthening PA, those who met only the strengthening guideline experienced less difficulty in two FL constructs (use of medical equipment/assistance and difficulty walking). Those who met the aerobic guideline reported even less difficulties in all three FL constructs. NHPI adults who met both the aerobic and strengthening guidelines experienced the least difficulties in all three FL constructs compared to those who met neither PA guidelines.

CONCLUSIONS

PA is associated with function in this adult NHPI population. Aerobic guidelines alone may be more beneficial than meeting the strengthening guideline alone; however, meeting both the aerobic and strengthening guidelines is most protective against FL.
