OBJECTIVE: COVID‐19 has changed diet and food shopping behaviors, but a lack of disaggregated data by racial and ethnic subgroup makes it challenging to identify whether specific populations are experiencing greater challenges in safely securing an adequate food supply and engaging in healthy eating behaviors during the pandemic. Thus, the objective of this study was to measure such changes among Asian–American (AA) adults, overall and by ethnic subgroup. METHODS: Using a nationally derived nonprobability sample, 3084 AA adults were recruited, including 1737 East Asian, 570 South Asian, 587 Southeast Asian, and 124 multiethnic Asian adults. Participants completed an online survey with questions related to sociodemographics, health status, and diet and food shopping behaviors, including questions related to COVID‐19. Logistic and linear regression were used to compare differences in survey responses by Asian ethnic subgroup. RESULTS: Compared to other AA subgroups, a higher percentage of Asian Indian (17%), Filipino (13%), Vietnamese (12%), and Korean (11%) adults reported no longer getting food resources they were receiving before COVID‐19 (e.g., mobile meals, food pantry items). The percentage of Filipino (8%) and Vietnamese (7%) adults who reported not having enough money to buy food they need was also higher than other AA subgroups. And a higher percentage of Asian Indian adults (7%) reported not having a way to get to the food store since COVID‐19 than other AA subgroups. CONCLUSIONS: Previous work has not included disaggregated data, which may mask important disparities in food access and food insecurity among people hit hardest by COVID‐19, such as Filipino, Vietnamese, and Asian Indian households.

There are stark racial and ethnic disparities in the social consequences and health impact of COVID-19 across the United States, with important differences between racial/ethnic groups. Several reports, for example, indicate an increase in incidents of discrimination among Asian-American (AA) adults, which may contribute to anxieties about leaving home, including trips to the grocery store. 1 Emerging data from several geographic locations also suggest a higher case fatality rate among AAs compared to other racial/ethnic groups. 2 The higher case fatality rate may be due to limited healthcare access; lower willingness to be tested; late presentation at the hospital when symptoms are already severe; and increased background prevalence of risk factors for severe illness such as diabetes and hypertension in specific Asian subgroups (e.g., Filipinos, South Asians). 3 AA adults also make up a large share of essential workers, including healthcare and food retail occupations, 4-6 which may put them at higher risk of infection. While published case rates are low, the true burden of COVID-19 in the AA population may be underestimated due to race/ethnicity mischaracterization and a lack of data disaggregated by Asian ethnic subgroup. 7 There is also growing evidence to suggest that COVID-19 has disrupted food shopping patterns and diet behaviors, potentially due to reduced store hours, food item shortages, and fear of infection. 8 Results from a nationally representative survey indicate that, although Asian households were not significantly more food insecure than White households in late April, 2020, Asian households were more likely to be afraid to go out to buy food, and were more likely to face transportation issues when purchasing food. 9 Unfortunately, the researchers were not able to stratify results by Asian ethnic subgroup, which may have masked important heterogeneity in responses among AA adults.

Understanding heterogeneity in changes in food shopping and diet behaviors among AA adults during the COVID-19 pandemic is an important step towards understanding drivers of recent obesity trends. Recent research from the United Kingdom, for example, suggests that the COVID-19 crisis (April-May 2020) may have contributed to a decline in weight-gain protective behaviors (e.g., snacking frequency) and experiencing barriers to weight management, 10 especially among obese participants and those with a high level of stress. 11 Although AAs have a historically low prevalence of obesity relative to other racial and ethnic groups, 12 evidence from local and national studies indicate that obesity has been increasing among AA adults, and is of particular public health concern for specific subgroups such as Filipinos and Asian Indians. 3 Moreover, anthropomorphic differences (i.e., high percent body fat, low muscle mass) in Asian populations have led to the broad consensus that current definitions of overweight and obesity likely underestimate the true burden of the metabolic effects of obesity in AA. [13] [14] [15] Previous work suggests that food insecurity is linked to obesity via irregular eating patterns, including periods of under-consumption of nutrient-rich foods when resources are insufficient and overconsumption of low-cost, calorie-dense foods when resources are sufficient. 16 This is concerning because food insecurity is high and participation in the Supplemental Nutrition Assistance Program (SNAP) is low in specific AA subgroups (e.g., Vietnamese households). 17 The lack of disaggregated data on AA ethnicity makes it challenging to identify whether specific subgroups are experiencing greater challenges in safely securing an adequate food supply and engaging in healthy eating behaviors during the pandemic. Though previous research has reported on changes in weight-gain related behaviors in the general population, 10, 11 no previous work has examined how COVID-19 has changed diet and food shopping behaviors of AAs using disaggregated data. Therefore, the objective of this study was to measure such changes among AAs, overall and by ethnic subgroup. It was hypothesized that Southeast Asian adults would be less likely than East Asian adults to have sufficient resources (e.g., money, food assistance benefits) for safely acquiring an adequate supply of food; and South Asian adults would report buying healthier food to prepare for the pandemic.

Using a nationally derived nonprobability sample, 3084 AA adults were recruited from June 9 to 15, 2020. Dynata, an online surveying company that recruits volunteer research participants through their online panels, other online communities, social networks, and Web sites, 18 was used to recruit the sample. Dynata applies a 3-stage randomization process to match participants with surveys they are likely to be eligible for and complete, with proprietary quality control procedures to ensure participants do not take the same survey twice. To reduce selection bias associated with the topic of the survey, invitations did not include specific details of the survey. Participants who completed the survey received points that can be redeemed for various incentives, including cash, lotteries, or donations to charity.

Potential participants completed an online consent, followed by a brief pre-screening questionnaire. Eligibility criteria included identifying as Asian, being age 18 years and older, and English literacy. The survey was completed on either a personal computer, laptop, tablet, or mobile phone. Open REDCap, an online survey platform, was used to create and distribute the survey. 19 The survey was designed to assess sociodemographics, health status, food shopping behaviors, and changes in behaviors due to COVID-19.

Sociodemographic and food insecurity questions were derived from the 2017-2018 National Health and Nutrition Examination Survey. 20 The survey included 10 self-reported health outcome items from the Patient Reported Outcomes Measurement Information System and a single-item, self-reported question of diet quality. 21, 22 A 10-item version of the Marin Short Acculturation Scale was also included in the survey, which yields a total acculturation score ranging from 10 to 50. 23 To be consistent with similar research studies, questions regarding changes in food shopping behaviors were derived from a COVID-19 food survey implemented by nutrition and public health experts at the University of Tennessee, Knoxville. 8 The sample was recruited to approximately match the distribution of gender and age of Asian adults residing in the U.S. 24 Duplicate responses (n = 37) and implausible skip patterns (n = 29) were dropped. The final sample included 1737 East Asian, 570 South Asian, 587 Southeast Asian, and 124 multiethnic Asian (n = 3018) adults ( 

Descriptive analysis was performed on the total sample, as well as by business. Compared to East Asian adults, however, Southeast Asian adults were more likely to report a decrease in work hours (9%; p = 0.01), and job loss was highest among Vietnamese adults (11%; Table 3 ).

Approximately 11% of respondents reported there were food resources they were receiving before COVID-19 that they are now not getting, with a higher percentage among Korean, Asian Indian, Filipino, and Vietnamese adults (Table 3) . Participation in SNAP was also higher among these subgroups; and Filipino and Vietnamese adults were more likely to report not having enough money to buy the food they need. Compared to East Asian adults, a higher percentage of South Asian adults reported not having a way to get to the food store since COVID-19 than other groups (p < 0.001), including Asian Indian adults; and a higher percentage of South Asian adults reported not going to the food store in the last week (p < 0.001). In addition, a higher percentage of Korean, Asian Indian, and Filipino adults reported that the store only had a little of what they needed.

A lower percentage of East Asian adults reported buying more fruits, vegetables, fish/seafood, and beans/legumes to prepare for COVID-19 (Table 3) on collecting disaggregated data, which enabled us to identify differences by Asian ethnic subgroups. In contrast, previous surveys, including industry data, 27, 28 have not collected or reported disaggregated data, which may mask important disparities in food access and food insecurity, and thus key differences in obesity risk, among groups hit hardest by the COVID-19 pandemic, such as Filipino, Vietnamese, and Asian Indian communities. Thus, future research should collect and report survey responses by racial and ethnic subgroups, especially Asian ethnic subgroups, which often are lumped together or classified as "other" or "multi-ethnic."
