Background: Asian Americans are one of the fastest growing minority populations in the United States. With increases in the older adult population too, there needs to be research dedicated to their health. Past studies have shown that social isolation and loneliness predict greater physical, mental, and cognitive decline. This literature review was conducted to address this emerging need to understand the scope of research focused on social isolation and Asian American older adults. Methods: The PRISMA guidelines were used to guide this review. Four interdisciplinary databases searched were: PubMed, CINAHL, PsychINFO, and AgeLine. Search terms included variations on the words social isolation, loneliness, Asian Americans, and older adults. The date of the last search was July 6th, 2016. Articles were reviewed based on 5 eligibility criteria: (1) topic relevance, (2) study participants > 60 years of age, (3) Asian immigrants as main participants, (4) conducted in a Western country, and (5) published in the English language. The remaining studies were assessed on eight categories: ethnic group, health topic, geographic location, subject population, recruitment site, study design, outcomes accessed, and outcomes measures. Results: The search yielded 203 articles from the four databases. 49 articles were removed as duplicates. The 154 remaining studies were reviewed based on their abstract and 34 met the eligibility criteria and underwent full text review. Existing research has focused primarily on immigrant Chinese and Korean older adult populations located in major gateway cities (ex: Los Angeles, New York City). Studies were largely observational studies that were conducted using small community-based samples which makes generalizability difficult. There were zero interventional studies. Conclusions: There are critical gaps in the literature on social isolation in Asian immigrant populations. Future studies should prioritize health promotion intervention research and focus on diverse understudied Asian subgroups (e.g. South Asians, Cambodians, Filipinos). Potential pitfalls of this literature review include: accessing only four major databases, limiting searches to after 1995, and studies were conducted throughout countries with different healthcare systems

We used the Racial and Ethnic Approaches to Community Health Across the US (REACH US) Risk Factor Survey from 2009 through 2012 to examine the association between body mass index (BMI, calculated as kg/m2) and 3 cardiovascular disease risk factors among Chinese Americans in New York City. We used traditional BMI cut points and cut points modified for the Asian population. Compared with normal/underweight Chinese American adults (BMI <23.0), obese Chinese American adults (BMI >/=27.5) had significantly higher odds of having each risk factor in fully adjusted logistic regression models: diabetes (odds ratio [OR], 4.2; 95% confidence interval [CI], 2.8-6.2), high blood pressure (OR, 5.5; 95% CI, 3.9-7.7), and high cholesterol (OR, 1.7; 95% CI, 1.2-2.4). Regression results were similar across BMI definitions, suggesting that both BMI categorizations should be considered in CVD research among Chinese Americans.

INTRODUCTION: Neighborhood factors are increasingly recognized as determinants of health. Neighborhood social cohesion may be associated with physical activity, but previous studies examined data aggregated across racial/ethnic groups. We assessed whether neighborhood social cohesion was associated with physical activity in a nationally representative data set and explored the role of race/ethnicity. METHODS: We combined National Health Interview Survey data from 2013 and 2014 (n = 64,754) and constructed a neighborhood social cohesion score by summing responses to 4 questions. The outcome of meeting aerobic physical activity guidelines was defined as 150 or more minutes per week of moderate activity or 75 or more minutes of vigorous activity. Multivariable models regressing physical activity on neighborhood social cohesion were adjusted for demographic factors; interaction analyses assessed effect modification by race/ethnicity. RESULTS: In adjusted analyses, a 1-unit increase in the neighborhood social cohesion score was associated with higher odds of meeting physical activity guidelines (odds ratio [OR], 1.04; 95% confidence interval [CI], 1.03-1.05). Neighborhood social cohesion and physical activity were associated among non-Hispanic white adults (OR, 1.30; 95% CI, 1.20-1.42) and Hispanic adults (OR, 1.18; 95% CI, 1.03-1.34]) but not among non-Hispanic black or Asian American adults (Chinese, Filipino, and Asian Indians). CONCLUSION: Neighborhood social cohesion was associated with meeting physical activity guidelines in a nationally representative sample; this association may be most meaningful for non-Hispanic white and Hispanic populations. Additional studies are needed to identify neighborhood factors that help non-Hispanic black and Asian Americans to meet physical activity guidelines.

Asian Americans have lower levels of physical activity (PA) compared to other racial/ethnic groups; however, there is little understanding of the social and cultural determinants of PA in this population. Few analyses describe specific PA domains (occupation-, transportation-, recreation-related), focus on one Asian subgroup, or use validated scales. The study objective was to assess the association between acculturation and activity behaviors (meeting 2008 PA guidelines, activity minutes by PA domain, sitting time) in a cross-sectional sample of urban-dwelling, Chinese American immigrants. Data were from the Chinese American Cardiovascular Health Assessment (CHA CHA) 2010-11 among participants with valid reports of PA minutes, assessed by the WHO Global Physical Activity Questionnaire (n = 1772). Acculturation was assessed using the Stephenson Multigroup Acculturation Scale, a 32-item instrument which characterizes two acculturative dimensions: ethnic society (Chinese) immersion and dominant society (American) immersion (maximum possible scores = 4). Multivariable models regressing activity behaviors on acculturation were run, adjusting for age, sex, household income, education, and age at immigration. Ethnic society immersion was high (mean = 3.64) while dominant society immersion was moderate (mean = 2.23). Higher ethnic society immersion was associated with less recreation-related PA (- 40.7 min/week); higher dominant society immersion was associated with a higher odds of meeting PA guidelines (OR: 1.66 (1.25, 2.20), p < 0.001) and more recreation-related PA (+ 36.5 min/week). Given low PA levels in Chinese adults in China, results suggest that PA for leisure may increase and become a more normative behavior among Chinese American immigrants with acculturation. Understanding acculturation level may inform strategies to increase PA in Chinese Americans.

Fifty years ago, the term model minority was coined to describe the extraordinary ability of Asian Americans to overcome hardship to succeed in American society. Less well-known is how the model minority stereotype was cultivated within the context of Black-White race relations during the second half of the 20th century, and how this stereotype, in turn, has contributed to the understanding and prioritization of health disparities experienced by Asian Americans. The objectives of this article are to define the model minority stereotype, present its controversies, and provide examples of its social and health-related consequences (ie, implications for obesity and tobacco) across multiple levels of society and institutions. A salient theme throughout the examples provided is the limitation of data presented at the aggregate level across all Asian subgroups which masks meaningful disparities. The intent is to increase the visibility of Asian Americans as a racial/ethnic minority group experiencing chronic disease health disparities and deserving of health-related resources and consideration.

PURPOSE: To explore correlates of meeting recommended physical activity (PA) goals among middle-aged and older Korean Americans at risk for diabetes mellitus (DM). DESIGN AND METHODS: PA patterns and their correlates were assessed among 292 middle-aged and older Korean Americans at risk for DM living in New York City using cross-sectional design of baseline information from a diabetes prevention intervention. PA was assessed by self-report of moderate and vigorous activity, results were stratified by age group (45-64 and 65-75 years), and bivariate analyses compared individuals performing less than sufficient PA and individuals performing sufficient PA. Logistic regression was used to calculate adjusted odds ratios predicting sufficient PA. FINDINGS: After adjusting for sex, age group, years lived in the United States, marital status, health insurance, and body mass index (BMI), sufficient PA was associated with male sex, older age, lower BMI, eating vegetables daily, and many PA-specific questions (lack of barriers, confidence, and engagement). When stratified by age group, male sex and eating vegetables daily was no longer significant among Koreans 65 to 75 years of age, and BMI was not significant for either age group. CONCLUSIONS: PA interventions targeting this population may be beneficial and should consider the roles of sex, age, physical and social environment, motivation, and self-efficacy. CLINICAL RELEVANCE: Clinical providers should understand the unique motivations for PA among Korean Americans and recognize the importance of culturally driven strategies to enable lifestyle changes and support successful aging for diverse populations.

We examined the association between years living in the United States and overweight risk among a community sample of Filipino adult immigrants living in the New York metropolitan area. We found a significant and adverse association between years living in the United States and overweight risk. Compared with Filipinos who lived in the United States less than 5 years, those who lived in the United States 10 years or longer had a higher overweight risk; this association was present only among Filipinos who migrated to New York metropolitan area at 30 years of age or younger. Studies on causal mechanisms explaining this pattern are needed.

Health information can potentially mitigate adverse health outcomes among ethnic minority populations, but little research has examined how minorities access health information. The aim of this study was to examine variations in the use of health information sources among Asian American (AA) subgroups and to identify differences in characteristics associated with the use of these sources. We analyzed data from a foreign-born community sample of 219 Asian Indians, 216 Bangladeshis, 484 Chinese, and 464 Koreans living in New York City. Results found that use of health information sources varied by AA subgroup. Print media source use, which included newspapers, magazines, and/or journals, was highest among Chinese (84%), Koreans (75%), and Bangladeshis (80%), while radio was most utilized by Chinese (48%) and Koreans (38%). Television utilization was highest among Bangladeshis (74%) and Koreans (64%). Koreans (52%) and Chinese (40%) were most likely to use the Internet to access health information. Radio use was best explained by older age and longer time lived in the United States, while print media were more utilized by older individuals. Results also highlighted differences in native-language versus non-native-language media sources for health information by subgroup. Media sources can be used as a vehicle to disseminate health information among AAs.
