Both a strength and limitation of the current study was full consideration of Asian-American and American-Indian participants as distinct race/ethnicity groups. Because of smaller population sizes, epidemiological studies typically focus on White, Black, and Hispanic groups, and include smaller numbers of members from other groups (i.e. Asian American, Native American, Native Hawaiian, other Pacific-Islanders). These individuals of are often pooled (i.e. ‘other’ race/ethnicity) or omitted from reports (Johnston et al. 2016). For these reasons, it is difficult to place specific findings within the context of previous studies. Although the current study included a sizable number of American Indian (N: 499) and Asian American (N: 1781) participants, the available sample was still small in comparison with other groups (N: 7037–19 194), limiting statistical power and our ability to comment conclusively on non-significant associations observed specifically among American-Indian and Asian- American participants, especially when analyses were further stratified by gender (i.e., comparable ORs but larger confidence intervals). Future studies would benefit from larger minority recruitment and examination of subpopulations within race/ethnic groups, including those who identify with more than one race/ethnic group.
