Race and ethnicity are consequential constructs when it comes to exposure to air pollution. Persistent environmental racial/ethnic inequalities call for attention to identifying the factors that maintain them. We examined associations between racial residential segregation and racial/ethnic inequalities in exposure to three types of air pollutants. Using data from the Panel Study of Income Dynamics (1990-2011), the U.S. Census (1990-2010), and the Environmental Protection Agency, we tested the independent and joint contributions of race/ethnicity and metropolitan-level residential segregation on individual levels of exposure to air pollution nationwide. We found that racial and ethnic minorities were exposed to significantly higher levels of air pollution compared to Whites. The difference between minorities and Whites in exposure to all three types of air pollution was most pronounced in metropolitan areas with high levels of residential segregation. The environmental inequities observed in this study call for public health and policy initiatives to ameliorate the sources of racial/ethnic gaps in pollution exposure. Given the links between the physical environment and health, addressing such uneven environmental burdens may be a promising way to improve population health and decrease racial/ethnic inequalities therein.

Since the outbreak of COVID-19, Asians in the US have experienced a spike of racism. The goal of this paper is to examine the association between racial discrimination amid COVID-19 pandemic and depressive symptoms among Asian subgroups and to test whether communications about the incident with various sources moderate this relationship. Data come from an online survey conducted among 245 Asian Americans. Multiple linear regression analyses were conducted. COVID-19 racial discrimination was positively associated with depressive symptoms, and this association did not vary between Chinese Americans and other Asian subgroups. Communications with a spouse/partner buffered the mental burden of racial discrimination. Those who shared their experience in online ethnic communities displayed stronger depressive symptoms than who did not. These results suggest the potential benefit of communication with a spouse/partner in mitigating the mental burden of discrimination and call for more online mental health support for Asians.

The present study tests whether and how racial/ethnic identity moderates the psychological burden associated with racial discrimination. The theoretical concept of identity-relevant stressors suggests that racial discrimination will be associated with stronger psychological burden for people who put more values on their racial/ethnic backgrounds (i.e., racial/ethnic identity as an exacerbator). Conversely, racial/ethnic identity may be a protective resource to buffer any negative mental health consequences of racial discrimination (i.e., racial/ethnic identity as a buffer). We adjudicate these two competing hypotheses, while also examining whether the moderating effect of racial/ethnic identity varies by race/ethnicity or nativity. The data are from the 2013 National Epidemiologic Survey on Alcohol and Related Conditions-III. Our findings reveal a race/ethnicity-dependent pattern: High racial/ethnic identity functions as an exacerbator for Whites, American Indians/Alaska Natives, and Latinxs, but moderate racial/ethnic identity functions as a buffer for Asians and Blacks in handling racial discrimination. In addition, the moderating effect of racial/ethnic identity is more pronounced among the U.S.-born than the foreign-born. The present study contributes to the knowledge base by showing that racial/ethnic identity does not universally protect—nor does it universally exacerbate—the psychiatric burden of racial discrimination. Rather, whether it mitigates or intensifies the mental burden of racial discrimination depends on its level and race/ethnicity.

Ambient air pollution is a well-known risk factor of various asthma-related outcomes, however, past research has often focused on acute exacerbations rather than asthma development. This study draws on a population-based, multigenerational panel dataset from the United States to assess the association of childhood asthma risk with census block-level, annual-average air pollution exposure measured during the prenatal and early postnatal periods, as well as effect modification by neighborhood poverty. Findings suggest that early-life exposures to nitrogen dioxide (NO2), a marker of traffic-related pollution, and fine particulate matter (PM2.5), a mixture of industrial and other pollutants, are positively associated with subsequent childhood asthma diagnosis (OR = 1.25, 95% CI = 1.10–1.41 and OR = 1.25, 95% CI = 1.06–1.46, respectively, per interquartile range (IQR) increase in each pollutant (NO2 IQR = 8.51 ppb and PM2.5 IQR = 4.43 µ/m3)). These effects are modified by early-life neighborhood poverty exposure, with no or weaker effects in moderate- and low- (versus high-) poverty areas. This work underscores the importance of a holistic, developmental approach to elucidating the interplay of social and environmental contexts that may create conditions for racial-ethnic and socioeconomic disparities in childhood asthma risk.

Objectives: This study investigates whether and how racial discrimination is associated with ethnic-racial socialization in the family and how distinct aspects of ethnic-racial socialization influence children's ethnic and American identity among Filipino American and Korean American families. Method: The data are obtained from the Midwest Longitudinal Study of Asian American Families Project (N ϭ 1,580; 379 Filipino American youths and 377 parents, and 410 Korean American youths and 414 parents; M age of youths ϭ 15.01). Using the bootstrapping and maximum likelihood with missing values approaches, we conducted path analyses to test the hypothesized associations concurrently and longitudinally for each ethnic group. Results: Youth-reported racial discrimination was directly associated with weaker American identity, both concurrently and longitudinally. In concurrent models, racial discrimination experienced by both youth and parents was positively associated with youth-reported preparation for bias, which in turn was linked with stronger ethnic identity among Filipinos, whereas no indirect pathways reached statistical significance among Koreans. In longitudinal models, parent-reported discrimination was linked with higher levels of promotion of mistrust among both groups, which predicted weaker ethnic identity among Filipino youth but stronger American identity among Korean youth. Conclusions: The present study highlights how exposure to racial discrimination may have a lasting influence in cultural identity development among Asian Americans and possibly through ethnic-racial socialization in the family, which might have been shaped by such experiences. Our results also underscore the importance of considering the experiences of both children and parents in studies of discrimination and ethnic-racial socialization. Public Significance StatementUsing intergenerational and longitudinal data, the present study investigates the indirect links between racial discrimination and youth cultural identities via ethnic-racial socialization among Filipino American and Korean American youth and their families. Parental promotion of mistrust, which is related to parents' experience of racial discrimination, longitudinally pushes Filipino American youth away from their ethnic identity and pushes Korean American youth toward stronger American identity. Parental preparation of bias, which is associated with youths' experience of racial discrimination, is cross-sectionally associated with stronger ethnic identity among Filipino American youth.
