Introduction Given rising rates of breast cancer in parts of Asia, immigrant Asian American women in the United States may have higher rates of breast cancer than previously anticipated. This study examined breast cancer risk among Asian American women by nativity and percentage of life lived in the United States, accounting for established breast cancer risk factors. Methods We analyzed a breast cancer case-control data set of Asian American women living in the San Francisco Bay Area; this data set included 132 cases of women with breast cancer selected from a Surveillance, Epidemiology, and End Results cancer registry and 438 Asian American women without diagnosed breast cancer matched to cases by age and country of origin. We used logistic regression to compare 3 Asian American groups: US-born, immigrants who lived 50% or more of their life in the United States, and immigrants who lived less than 50% of their life in the United States. Results In the minimally adjusted and fully adjusted models, both groups of immigrant Asian American women had higher risk of breast cancer than US-born Asian American women. In the fully adjusted model, compared with US-born Asian American women, immigrant Asian American women who lived more than 50% of their life in United States were on average 3 times as likely (odds ratio = 3.00; 95% confidence interval, 1.56–5.75) and immigrants who lived less than 50% of their life in United States were on average 2.46 times as likely (odds ratio = 2.46; 95% confidence interval, 1.21–4.99) to have breast cancer. We found no difference in fully adjusted odds ratios of having breast cancer between the 2 immigrant groups. Conclusion This study provides preliminary evidence that breast cancer risk among immigrant Asian American women may be higher than among their US-born counterparts.

Asian American children and adolescents are an under-investigated subpopulation in obesity research. This study aimed to identify specific profiles of Asian subgroups at high risk of adolescent overweight with special attention to Asian ethnicity, socioeconomic status (SES), and their interaction. Multiple logistic regression models were fitted using a sample of 1533 Asian American adolescents ages 12–17 from the 2007–2012 California Health Interview Survey (CHIS). In addition to Asian ethnicity and socioeconomic status (assessed by family income and parental education level), age, gender, nativity, and two lifestyle variables, fast food consumption and physical activity, were also controlled for in these models. Key predictors of overweight in Asian American adolescents included certain Asian ethnicities (Southeast Asian, Filipino, and mixed ethnicities), low family income (< 300% of the Federal Poverty Level), and being male. Multiplicative interaction terms between low family income and two ethnicities, Southeast Asian and Vietnamese that had the lowest SES among Asian ethnic groups, were significantly associated with greatly elevated odds of being overweight (ORs = 12.90 and 6.67, respectively). These findings suggest that high risk of overweight in Asian American adolescents associated with low family incomes may be further elevated for those in low-income ethnic groups. Future research might investigate ethnic-group SES as a meaningful indicator of community-level socioeconomic disparities that influence the health of Asian Americans.

In the USA, cancer is the leading cause of death for Asian Americans and Pacific Islanders (AAPIs), but little is known about the unmet needs of AAPI cancer survivors, especially from a national perspective. Using a community-based participatory research approach, we partnered with the Asian and Pacific Islander National Cancer Survivors Network and the Asian American Cancer Support Network to design and conduct a cross-sectional survey to understand the unmet needs of a national sample of AAPI cancer survivors. We assessed unmet needs in 10 domains: day-to-day activities, financial expenses, emotional concerns, medical treatment, cancer information, home care, nutrition, physical concerns, family relationships, and spirituality. We also assessed self-reported measures related to quality of life. This national sample of AAPI cancer survivors included people from 14 states and two territories who had been diagnosed with a broad range of cancers, including cancer of the breast, ovary/uterus/cervix, prostate, blood, and other sites. Over 80 % reported at least one unmet need. Participants reported an average of 8.4 unmet needs, spanning an average of 3.9 domains. Most commonly reported were unmet needs pertaining to physical concerns (66 %), day-to-day activities (52 %), and emotional concerns (52 %). This is the first report of unmet needs in a national sample of AAPI cancer survivors with a range of different cancer types. It describes the areas of greatest need and points to the importance of devoting more resources to identifying and addressing unmet needs for the underserved population of AAPI cancer survivors.

A multimode approach using targeted recruitment strategies is an effective and feasible alternative to using a single recruitment method in identifying a representative, diverse control sample for population-based studies.
