Severe maternal morbidity among U.S.- and foreign-born Asian and Pacific Islander women in California.
Ontology highlight
ABSTRACT: Purpose
The purpose of the study was to examine the risk of severe maternal morbidity (SMM)-a composite of serious, potentially life-threatening conditions related to childbirth-among subgroups of nulliparous women with Asian and Pacific Islander race/ethnicity.Methods
This study used linked hospital discharge and vital record data California to identify nulliparous Asian and Pacific Islander women from 1997 to 2012 (n = 453,525). We examined the risk of SMM for 15 Asian and Pacific Islander subgroups and compared the risk between U.S.- and foreign-born women.Results
The risk of SMM was higher among Pacific Islander women than that among Asian women (148 and 127 cases per 10,000 births, respectively). Among Asian women, the risk of SMM ranged from 94 (Korean) to 165 (Filipina) cases per 10,000 births, and among Pacific Islander women, the risk ranged from 125 (Hawaiian) to 162 (Other). With the exception of Korean and Filipina women, relative risks of SMM for U.S.- versus foreign-born Asian and Pacific Islander women were similar.Conclusions
Differences in the risk of SMM exist between subgroups of the Asian and Pacific Islander community. These differences should be considered when conducting research on racial and ethnic differences of SMM and when counseling Asian and Pacific Islander women regarding their risk of SMM.

Project description:BackgroundAsian Americans (AA) are the fastest growing ethnic group in the United States with high proportions of immigrants. Nativity is important as cancer risk factors vary by country. We sought to understand differences in cancer mortality among AAs by nativity (foreign-born vs. U.S.-born).MethodsNinety-eight thousand eight hundred and twenty-six AA (Asian Indian, Chinese, Filipino, Japanese, Korean, Vietnamese) decedents with cancer-related deaths from U.S. death certificates (2008-2017) were analyzed. Thirteen cancers that contribute significantly to Asian-American cancer mortality were selected and categorized by etiology: tobacco-related, screen-detected, diet-/obesity-related, and infection-related. Ten-year age-adjusted mortality rates [AAMR; 95% confidence interval (CI); per 100,00] and standardized mortality ratios (SMR; 95% CI) using foreign-born as the reference group were calculated.ResultsOverall, foreign-born AAs had higher mortality rates than U.S.-born. Japanese U.S.-born males had the highest tobacco-related mortality rates [foreign-born AAMR: 43.02 (38.72, 47.31); U.S.-born AAMR: 55.38 (53.05, 57.72)]. Screen-detected death rates were higher for foreign-born than U.S.-born, except for among Japanese males [SMR 1.28 (1.21-1.35)]. Diet-/obesity-related AAMRs were higher among females than males and highest among foreign-born females. Foreign-born males and females had higher infection-related AAMRs than U.S.-born; the highest rates were foreign-born males-Korean [AAMR 41.54 (39.54, 43.53)] and Vietnamese [AAMR 41.39 (39.68, 43.09)].ConclusionsWe observed substantial heterogeneity in mortality rates across AA groups and by nativity. Contrary to the Healthy Immigrant Effect, most foreign-born Asians were dying at higher rates than U.S.-born AAs.ImpactDisaggregated analysis of AA cancers, targeted and culturally tailored cancer screening, and treatments for infections among foreign-born Asians is critical for cancer prevention efforts.

Project description:OBJECTIVES: We report cancer incidence, mortality, and stage distributions among Asians and Pacific Islanders (API) residing in the U.S. and note health disparities, using the cancer experience of the non-Hispanic white population as the referent group. New databases added to publicly available SEER*Stat software will enable public health researchers to further investigate cancer patterns among API groups. METHODS: Cancer diagnoses among API groups occurring from 1 January 1998 to 31 December 2002 were included from 14 Surveillance, Epidemiology, and End Results (SEER) Program state and regional population-based cancer registries covering 54% of the U.S. API population. Cancer deaths were included from the seven states that report death information for detailed API groups and which cover over 68% of the total U.S. API population. Using detailed racial/ethnic population data from the 2000 decennial census, we produced incidence rates centered on the census year for Asian Indians/Pakistanis, Chinese, Filipinos, Guamanians, Native Hawaiians, Japanese, Kampucheans, Koreans, Laotians, Samoans, Tongans, and Vietnamese. State vital records offices do not report API deaths separately for Kampucheans, Laotians, Pakistanis, and Tongans, so mortality rates were analyzed only for the remaining API groups. RESULTS: Overall cancer incidence rates for the API groups tended be lower than overall rates for non-Hispanic whites, with the exception of Native Hawaiian women (All cancers rate = 488.5 per 100,000 vs. 448.5 for non-Hispanic white women). Among the API groups, overall cancer incidence and death rates were highest for Native Hawaiian and Samoan men and women due to high rates for cancers of the prostate, lung, and colorectum among Native Hawaiian men; cancers of the prostate, lung, liver, and stomach among Samoan men; and cancers of the breast and lung among Native Hawaiian and Samoan women. Incidence and death rates for cancers of the liver, stomach, and nasopharynx were notably high in several of the API groups and exceeded rates generally seen for non-Hispanic white men and women. Incidence rates were lowest among Asian Indian/Pakistani and Guamanian men and women and Kampuchean women. Asian Indian and Guamanian men and women also had the lowest cancer death rates. Selected API groups had less favorable distributions of stage at diagnosis for certain cancers than non-Hispanic whites. CONCLUSIONS: Possible disparities in cancer incidence or mortality between specific API groups in our study and non-Hispanic whites (referent group) were identified for several cancers. Unfavorable patterns of stage at diagnosis for cancers of the colon and rectum, breast, cervix uteri, and prostate suggest a need for cancer control interventions in selected groups. The observed variation in cancer patterns among API groups indicates the importance of monitoring these groups separately, as these patterns may provide etiologic clues that could be investigated by analytic epidemiological studies.

Project description:BackgroundAsian American and Native Hawaiian/Pacific Islanders (AANHPI) are the fastest growing minority in the United States. Cancer is the leading cause of death for AANHPIs, despite relatively lower cancer morbidity and mortality. Their recent demographic growth facilitates a detailed identification of AANHPI populations with higher cancer risk.MethodsAge-adjusted, sex-stratified, site-specific cancer mortality rates from California for 2012 to 2017 were computed for AANHPI groups: Chinese, Filipino, South Asian, Vietnamese, Korean, Japanese, Southeast Asian (i.e., Cambodian, Hmong, Laotian, Thai), and Native Hawaiian and Other Pacific Islander (NHOPI). Regression-derived mortality rate ratios (MRR) were used to compare each AANHPI group to non-Hispanic whites (NHW).ResultsAANHPI men and women (total 40,740 deaths) had lower all-sites-combined cancer mortality rates (128.3 and 92.4 per 100,000, respectively) than NHWs (185.3 and 140.6) but higher mortality for nasopharynx, stomach, and liver cancers. Among AANHPIs, both NHOPIs and Southeast Asians had the highest overall rates including for colorectal, lung (men only), and cervical cancers; South Asians had the lowest. NHOPI women had 41% higher overall mortality than NHWs (MRR = 1.41; 95% CI, 1.25-1.58), including for breast (MRR = 1.33; 95% CI, 1.08-1.65) and markedly higher for endometrial cancer (MRR = 3.34; 95% CI, 2.53-4.42).ConclusionsAANHPI populations present with considerable heterogeneous cancer mortality patterns. Heightened mortality for infection, obesity, and tobacco-related cancers in Southeast Asians and NHOPI populations highlight the need for differentiated priorities and public health interventions among specific AANHPI populations.ImpactNot all AANHPIs have favorable cancer profiles. It is imperative to expand the focus on the currently understudied populations that bear a disproportionate cancer burden.

Project description:Gentrification, a racialized and profit-driven process in which historically disinvested neighborhoods experience an influx of development that contributes to the improvement of physical amenities, increasing housing costs, and the dispossession and displacement of existing communities, may influence the risk of severe maternal morbidity (SMM). Leveraging a racially diverse population-based sample of all live hospital births in California between 2006 and 2017, we examined associations between neighborhood-level gentrification and SMM. SMM was defined as having one of 21 procedures and diagnoses, as described in the SMM index developed by Centers for Disease Control and Prevention. We compared three gentrification measures to determine which operationalization best captures aspects of gentrification most salient to SMM: Freeman, Landis 3-D, and Urban Displacement Project Gentrification and Displacement Typology. Descriptive analysis assessed bivariate associations between gentrification and birthing people's characteristics. Overall and race and ethnicity-stratified mixed-effects logistic models assessed associations between gentrification and SMM, adjusting for individual sociodemographic and pregnancy factors while accounting for clustering by census tract. The study sample included 5,256,905 births, with 72,718 cases of SMM (1.4%). The percentage of individuals living in a gentrifying neighborhood ranged from 5.7% to 11.7% across exposure assessment methods. Net of individual and pregnancy-related factors, neighborhood-level gentrification, as measured by the Freeman method, was protective against SMM (OR = 0.89, 95% CI: 0.86-0.93); in comparison, gentrification, as measured by the Gentrification and Displacement Typology, was associated with greater risk of SMM (OR = 1.18, 95% CI: 1.14-1.23). These associations were significant among non-Hispanic White, non-Hispanic Black, and Hispanic individuals. Findings demonstrate that gentrification plays a role in shaping the risk of SMM among birthing people in California. Differences in how gentrification is conceptualized and measured, such as an emphasis on housing affordability compared to a broader characterization of gentrification's multiple aspects, may explain the heterogeneity in the directions of observed associations.

Project description:ObjectiveTo assess the prevalence and risk of severe maternal morbidity among delivery hospitalization for stillbirth compared with live birth deliveries.MethodsUsing data from the Office of Statewide Health Planning and Development in California, we performed a population-based cross-sectional study of 6,459,842 deliveries between 1999 and 2011. We identified severe maternal morbidity using an algorithm comprising diagnoses and procedures developed by the Centers for Disease Control and Prevention and used log-binomial regression models to examine the relative risk (RR) of severe maternal morbidity for stillbirth compared with live birth deliveries, adjusting for maternal demographic, medical, and obstetric characteristics. We also examined severe maternal morbidity prevalence by cause of fetal death among stillbirth deliveries.ResultsThe prevalence of severe maternal morbidity for stillbirth and live birth was 578 and 99 cases per 10,000 deliveries, respectively. After adjusting for maternal demographic, medical, and obstetric characteristics, the risk of severe maternal morbidity among stillbirth deliveries was more than fourfold higher (adjusted RR 4.77; 95% CI 4.53-5.02) compared with live birth deliveries. The severe maternal morbidity prevalence was highest among stillbirths caused by hypertensive disorders and placental conditions (24 and 19 cases/100 deliveries, respectively), and lowest among stillbirths caused by fetal malformations or genetic abnormalities (1 case per 100 deliveries).ConclusionWomen who have stillbirths are at substantially higher risk for severe maternal morbidity than women who have live births, regardless of cause of fetal death. The prevalence of severe maternal morbidity varies by cause of fetal death.

Project description:IntroductionRacism is a critical social determinant of health because it can have a direct impact on health and well-being, as well as infiltrate systems, policies, and practices. Few studies have explored the similarities and differences of experiences with racism and health between different minoritized groups. The objective of this paper is to examine how racism influences life experiences from the perspectives of Asian & Pacific Islander, Black, Latina, and Middle Eastern women.MethodsEleven online racially/ethnically homogeneous focus groups with a total of 52 participants were conducted in the U.S., with representation from the North, South, and West coast. The online focus groups were recorded, transcribed, and two were translated into English (from Vietnamese and Spanish). The data was coded through NVivo and analyzed through a series of team meetings to establish themes.ResultsParticipants reported experiences of racism and discrimination, including physical and verbal personal attacks. They shared the role of microaggressions in their daily life, along with the ubiquitous anti-Black sentiment discussed in every group. Our participants discussed the complexities of intersectionality in their experience of discrimination, specifically regarding immigration status, language spoken, and gender. Participants also reported the role of direct racism and vicarious racism (e.g., the experiences with racism of friends or family, awareness of racist incidents via the news) in affecting their mental health. Some effects were fear, stress, anxiety, depression, and self-censoring. For participants in the Black and Latina focus groups, mental health stressors often manifested into physical issues.DiscussionUnderstanding the nuances in experiences across racial/ethnic groups is beneficial in identifying potential interventions to prevent and address racism and its negative health impacts.

Project description:ObjectiveTo compare frequencies of risk factors and pregnancy outcomes in ethnic groups versus the combined total of Asian American, Native Hawaiian, and Pacific Islander (AANHPI) populations.MethodsUsing linked birth and fetal death certificate and maternal hospital discharge data (California 2007-2018), we estimated frequencies of 15 clinical and sociodemographic exposures and 11 pregnancy outcomes. Variability across 15 AANHPI groups was compared using a heat map and compared to frequencies for the total group (n = 904,232).ResultsAANHPI groups varied significantly from each other and the combined total regarding indicators of social disadvantage (e.g., range for high school-level educational or less: 6.4% Korean-55.8% Samoan) and sociodemographic factors (e.g., maternal age <20 years: 0.2% Chinese-8.8% Guamanian) that are related to adverse pregnancy outcomes. Perinatal outcomes varied significantly (e.g., severe maternal morbidity: 1.2% Korean-1.9% Filipino). No single group consistently had risk factors or outcome prevalence at the extremes, i.e., no group was consistently better or worse off across examined factors.ConclusionsSubstantial variability in perinatal risk factors and outcomes exists across AANHPI groups. Aggregation into "AANHPI" is not appropriate for outcome reporting.

Project description:OBJECTIVE:This study assesses the performance of the North American Association of Central Cancer Registries Asian/Pacific Islander Identification Algorithm (NAPIIA) to infer Hmong ethnicity. DESIGN AND SETTING:Analyses of electronic health records (EHRs) from 1 January 2011 to 1 October 2015. The NAPIIA was applied to the EHR data, and self-reported Hmong ethnicity from a questionnaire was used as the gold standard. Sensitivity, specificity, positive (PPV) and negative predictive values (NPVs) were calculated comparing the source data ethnicity inferred by the algorithm with the self-reported ethnicity from the questionnaire. PARTICIPANTS:EHRs indicating Hmong, Chinese, Vietnamese and Korean ethnicity who met the original study inclusion criteria were analysed. RESULTS:The NAPIIA had a sensitivity of 78%, a specificity of 99.9%, a PPV of 96% and an NPV of 99%. The prevalence of Hmong population in the sample was 3.9%. CONCLUSION:The high sensitivity of the NAPIIA indicates its effectiveness in detecting Hmong ethnicity. The applicability of the NAPIIA to a multitude of Asian subgroups can advance Asian health disparity research by enabling researchers to disaggregate Asian data and unmask health challenges of different Asian subgroups.

Project description:BackgroundSevere maternal morbidity (SMM) has increased in the United States by 45% in the last decade. While the recurrence of several adverse pregnancy outcomes from one pregnancy to the next has been established, the recurrence risk of SMM is unknown.ObjectiveTo determine whether women who have SMM in a first pregnancy are at increased risk of SMM in their second pregnancy, compared to women who did not have SMM in their first pregnancy.MethodsThis is a population-based study using linked vital statistics and hospital discharge records from the Office of Statewide Health Planning and Development in California from 1997 to 2012. The study population had their first two singleton births (live births or stillbirths) in California between 1997 and 2012 (n = 1 180 357). The primary exposure was SMM during the hospitalisation at first birth, and the primary outcome was SMM during the hospitalisation at second birth. Prevalence and risk ratios of SMM at second birth were computed for women who did and did not have SMM at first birth, as well as for certain specific indicators of SMM.ResultsOf the 1 180 357 women included in this analysis, 9088 (77 per 10 000 births) experienced SMM at first birth. Among these women, the prevalence of SMM at second birth was 470 per 10 000 births, compared to 68 per 10 000 births among women without SMM at first birth. This corresponded to an unadjusted risk ratio of 6.87 (95% CI 6.23, 7.57), which did not differ substantially when adjusted for factors known to be associated with SMM (6.42, 95% CI 5.86, 7.13).ConclusionWomen experiencing SMM in their first pregnancy were at an approximately sixfold increased risk of experiencing SMM in their second pregnancy.

Project description:BackgroundMonitoring rates of severe maternal morbidity (such as eclampsia and uterine rupture) is useful to assess the quality of obstetric care, particularly in low and lower-middle-income countries (LMICs).MethodsWe undertook a systematic review characterising the proportion and causes of severe maternal morbidity in the Asia Pacific region. We searched Medline, Embase, Cochrane CENTRAL library and the World Health Organization Western Pacific Index database for studies in the Asia-Pacific reporting maternal morbidity/near miss using a predefined search strategy. We included cohort, case-control and cross-sectional studies published in English before September 2020. A meta-analysis was performed calculating the overall proportion of near miss events by sub-region, country, near miss definition, economic status, setting and cause using a random-effects model.FindingsWe identified 26,232 articles, screened 24,306 and retrieved 454 full text articles. Of these, 197 studies spanning 27 countries were included. 13 countries in the region were not represented. There were 30,183,608 pregnancies and 100,011 near misses included. The total proportion of near miss events was 4•4 (95% CI 4•3-4•5) per 1000 total births. The greatest proportion of near misses were found in the Western Pacific region (around Papua New Guinea) at 11•8 per 1000 births (95% CI 6•6-17•1; I2 96.05%). Low-income countries displayed the greatest proportion of near misses (13•4, 95% CI 6•0-20•7), followed by lower-middle income countries (11•1; 95% CI 10•4 - 11•9). High-income countries had the lowest proportion (2•2, 95% CI 2•1-2•3). Postpartum haemorrhage was the most common near miss event (5•9, 95% CI 4•5-7•2), followed by eclampsia (2•7, 95% CI 2•4 - 2•9).InterpretationThere is a high burden of severe maternal morbidity in the Asia-Pacific. LMICs are disproportionately affected. Most of the common causes are preventable. This provides an opportunity to implement targeted interventions which could have major clinical impact.
