Do inferences about mortality rates and disparities vary by source of mortality information?

The Roles of Adolescent Occupational Expectations and Preparation in Adult Suicide and Drug Poisoning Deaths within a Shifting Labor Market

Research suggests that economic declines contribute to mortality risks from suicide and drug poisoning, but how the economy impacts individuals' risks of these deaths has been challenging to specify. Building on recent theoretical advances, we investigate how adolescent occupational expectations and preparation contribute to suicide and drug poisoning deaths in a shifting economy. We use High School and Beyond data linked to adult mortality records for men that were exposed to a decline in labor market share and wages in predominantly blue-collar occupations during early adulthood. We find that adolescent men who expected these occupations had increased risks of suicide and drug poisoning death as adults net of educational and occupational attainment in early adulthood. Family background and occupational preparation are risk factors for death by drug poisoning but not suicide. Our findings improve our understanding of how labor market uncertainty shapes individuals' vulnerability to suicide and drug poisoning death.

Can administrative health data be used to estimate population level birth and child mortality estimates? A comparison of India's Health Information Management System data with nationally representative survey data

•

HMIS covers a large proportion of births, but a smaller fraction of child deaths compared to estimates from surveys.

•

Birth and death coverage in HMIS, while incomplete, has been improving nationally and for many states.

•

States that have improved HMIS reporting, should be studied for replicating best practices.

•

HMIS can provide signals for real time policy decisions, if used with due consideration of its limitations.

•

Including patient socioeconomic and demographic traits in HMIS, could further bolster its utility in population health.

Association of Job Expectations Among High School Students With Early Death During Adulthood

Importance

Deaths from self-injury are increasing. Understanding the sources of risk is important for prevention and treatment.

Objective

To estimate the risks of suicide and drug poisoning deaths among adult men whose adolescent occupational expectations were not met in adulthood.

Design, Setting, and Participants

This cohort study included a sample of men interviewed as part of the High School and Beyond study, a nationally representative study of US high school sophomores and seniors in 1980, who were interviewed every 2 years through 1986; those who were sophomores in 1980 were reinterviewed in 1992. Men who survived to 1992 and reported occupational expectations were included in the present study. Death records prior to 2018 were linked to mortality databases and released in 2019. Data analysis was conducted from May to October 2020.

Exposure

Occupational expectations.

Main Outcomes and Measures

Survival or death by suicide, drug poisoning, chronic liver disease, heart disease, cancer, or some other cause, categorized from International Classification of Diseases, Ninth Revision and Tenth Revision codes. Competing risk Fine-Gray survival models regressed cause of death on adolescent occupational expectations and covariates.

Results

The 11 680 men in the High School and Beyond cohort study had a median (interquartile range) age of 29 (28-30) years in 1992, when the analysis of their future mortality began. Most men survived until 2015 (11 060 [weighted percentage, 95.0%]). Reported causes of death were suicide (60 [weighted percentage, 0.5%]), drug poisoning (40 [weighted percentage, 0.4%]), chronic liver disease (20 [weighted percentage, 0.2%]), heart disease (130 [weighted percentage, 1.0%]), cancer (100 [weighted percentage, 1.0%]), and other (280 [weighted percentage, 2.0%]). Subhazard ratios for death by suicide and drug poisoning were 2.91 (95% CI, 1.07-7.88; P = .04) and 2.62 (95% CI, 1.15-5.94; P = .02) times higher, respectively, among those who in 1980 expected to hold a subbaccalaureate occupation that later declined in labor market share compared with those with professional occupational expectations. The actual job held by men did not attenuate the hazards of deaths from suicide and drug poisoning.

Conclusions and Relevance

In this cohort study, men whose occupational expectations were not met because of labor market declines were at a higher risk of death from suicide or drug poisoning than men with different occupational expectations. Interventions to mitigate labor market changes should account for individuals' expectational ideals.

Vital Status Ascertainment for a Historic Diverse Cohort of U.S. Women

BACKGROUND

Studies linking large pregnancy cohorts with mortality data can address critical questions about long-term implications of gravid health, yet relevant US data are scant. We examined the feasibility of linking the Collaborative Perinatal Project, a large multiracial U.S. cohort study of pregnant women (n = 48,197; 1959-1966), to death records.

METHODS

We abstracted essential National Death Index (NDI) (1979-2016) (n = 46,428). We performed a linkage to the Social Security Administration Death Master File through 2016 (n = 46,450). Genealogists manually searched vital status in 2016 for a random sample of women (n = 1,249). We conducted agreement analyses for women with abstracted data among the three sources. As proof of concept, we calculated adjusted associations between mortality and smoking and other sociodemographic factors using Cox proportional hazards regression.

RESULTS

We successfully abstracted identifying information for most of the cohort (97%). National Death Index identified the greatest proportion of participants deceased (35%), followed by genealogists (31%) and Death Master File (23%). Estimates of agreement (κ [95% confidence interval]) between National Death Index and Death Master File were lower (0.52 [0.51, 0.53]) than for National Death Index and genealogist (0.66 [0.61, 0.70]). As expected, compared with nonsmokers, smoking ≥1 pack per day was associated with elevated mortality for all vital sources and was strongest for National Death Index.

CONCLUSIONS

Linking this historic cohort with mortality records was feasible and agreed reasonably on vital status when compared with other data sources. Such linkage enables future examination of pregnancy conditions in relation to mortality in a diverse U.S. cohort.

Which Aspects of Education Matter for Early Adult Mortality? Evidence from the High School and Beyond Cohort

What dimensions of education matter for people's chances of surviving young adulthood? Do cognitive skills, non-cognitive skills, course taking patterns, and school social contexts matter for young adult mortality, even net of educational attainment? We analyze data from High School & Beyond-a nationally representative cohort of ~25,000 high school students first interviewed in 1980. Many dimensions of education are associated with young adult mortality, and high school students' math course taking retain their associations with mortality net of educational attainment. Our work draws on theories and measures from sociological and educational research and enriches public health, economic, and demographic research on educational gradients in mortality that has almost exclusively relied on ideas of human capital accumulation and measures of degree attainment. Our findings also call on social and education researchers to engage together in research on the life-long consequences of educational processes, school structures, and inequalities in opportunities to learn.

Performance of the Meta-Analysis Global Group in Chronic Heart Failure Score in Black Patients Compared With Whites

BACKGROUND

Risk stratification is critical in heart failure (HF) and the Meta-Analysis Global Group in Chronic HF (MAGGIC) score is a validated tool derived from ~40,000 patients. However, few of these patients self-identified as black, raising uncertainty regarding performance in blacks with HF.

METHODS AND RESULTS

This study analyzed a racially diverse group of 4046 patients (1646 black and 2400 white) from a single center from 2007 to 2015. Baseline characteristics were collected to tabulate MAGGIC score and test its discrimination and calibration within race groups. The primary end point was all-cause mortality. Death was detected using system records and the social security death master file. Discrimination was tested using Cox models of MAGGIC score stratified by race, and combined analysis including MAGGIC, race, and MAGGIC×race. Calibration was assessed using linear regression models and plots of observed versus predicted data. Overall, 901 (21%) patients died during 1-year follow-up. MAGGIC score discrimination was similar in both race groups in terms of C statistic (0.707±0.027 versus 0.725±0.014, for black versus white; P=0.556) and the hazard ratio (HR) per MAGGIC point was 1.12 in black patients (95% CI, 1.10-1.14) and 1.13 in white patients (95% CI, 1.12-1.14). Race was a significant correlate of survival, with better survival in black patients compared with white (HR, 0.66; 95% CI, 0.56-0.78), but the interaction of MAGGIC×race was not significant (β=-0.013; P=0.16), and adding race to the model did not improve discrimination (C statistic for MAGGIC versus MAGGIC+race, 0.721 versus 0.722; P=0.79). In calibration testing, the slope was not significantly different from 1 in either group, but the groups differed from each other, and it was closer to unity among black patients (0.94 versus 1.4; P=0.004).

CONCLUSIONS

These data support the use of the MAGGIC score to risk stratify black patients with HF.

Washington State abdominal aortic aneurysm-related mortality shows a steady decline between 1996 and 2016

OBJECTIVE

Management of abdominal aortic aneurysms (AAA) has undergone considerable advances over the last two decades. Our aim was to evaluate AAA-related mortality trends in Washington State over a 21-year period and to assess variation in AAA-related mortality by sex, race, and county over the same time period. We hypothesized that a significant decrease in AAA-related mortality in Washington State would be noted.

METHODS

Death certificate records were obtained from the Washington State Department of Health from 1996 to 2016. Records in which AAA was listed as an underlying or associated cause of death were selected for analysis. Age-standardized mortality rates for each year were calculated using the 2016 Washington State population as the standard. Mortality trends were compared by sex and race using linear regression. County-specific age-standardized ruptured AAA (rAAA) mortality rates were compared using a Kruskal-Wallis test.

RESULTS

Of the 1,014,039 deaths occurring in Washington State during the study period, 4438 (0.4%) had AAA listed as an underlying or associated cause of death (66.1% male; 94.8% white; mean age at death, 79.4 ± 9.3 years). In 64.1% of the cases, AAA was listed as the underlying cause of death. AAA-related mortality rates decreased by 62.1% over the 21 years from 5.8 to 2.2 deaths per 100,000. Notably, there was a statistically significant decrease in rAAA-related mortality rates (from 3.2 to 0.95 per 100,000, a decrease of 0.12 deaths/100,000/year; 95% confidence interval, 0.11-0.14; r² = 0.95). Men had a significantly steeper decrease in age-standardized AAA-related mortality rates with a 55% decrease (from 6.5 to 3.0 per 100,000) vs a 41% decrease (2.4 to 1.4 per 100,000) among women. Men were younger at the time of death than women (78.1 ± 9.4 years vs 81.9 ± 8.6 years, respectively; P < .001). Individuals who were white had a significantly steeper decrease in age-standardized AAA-related mortality rates with a 53% decrease (from 5.3 to 2.5 per 100,000) compared with a 13% decrease among individuals who were nonwhite (from 1.5 to 1.3 per 100,000). Age-standardized rAAA-related mortality rates varied by county (P < .001).

CONCLUSIONS

Age-standardized AAA-related mortality rate has decreased in Washington State between 1996 and 2016, with a notable decrease in the rAAA-related mortality rate. The decrease in AAA-related mortality rates varied by sex and race. Additionally, rAAA-related mortality rates differed between counties. These observations are a first step toward regional population assessments. Future work to understand the sources of variation can influence public health interventions on a state level.
