Multigenerational inequalities of opportunity in health outcomes.

This paper studies multigenerational health transmission mechanisms in Australian panel data. Using inequality-of-opportunity (IOP) models, we demonstrate that grandparental socioeconomic status (SES) is an important determinant of personal health, even after controlling for health and SES at the parental level. Our findings hold over a range of health/biomarkers of individuals' physical and mental well-being and appear to be especially sensitive to educational outcomes on the father's side. Since ingrained socioeconomic (dis)advantages that persist over multiple generations may be indicative of social class, our results suggest that subtle attitudinal and behavioural characteristics associated with this variable may be a key factor driving health disparities.

The Medical Outcome Study Social Support Survey (MOS-SSS): A psychometric systematic review.

AIMS: To evaluate and synthesize psychometric properties of the MOS-SSS and to identify quality versions of MOS-SSS for use in future research and practice. DESIGN: A psychometric systematic review. DATA SOURCES: Articles about the translation, adaptation, or validation of the MOS-SSS in Medline, PubMed, CINAHL, and Web of Science and their reference lists published before 11 November 2022. REVIEW METHODS: The review followed the Consensus Standards for the Selection of Health Measurement Instruments guidelines. RESULTS: The review included 35 articles. Eleven versions of MOS-SSS (3, 4, 5, 6, 8, 12, 13, 16, 18, 19, and 22 items) have been validated in various populations and 13 languages. Of 14 studies developing a translated version of MOS-SSS, four studies performed both an experts' evaluation of content validity and a face validity test; two studies reported translation evaluation in the form of a content validity index. Of 35 studies, six performed both exploratory factor analysis and confirmatory factor analysis for structural validity; hypotheses and measurements for construct validity testings were often not clearly stated; two examined criterion validity; and four assessed cross-cultural validity. Internal consistency reliabilities were commonly examined by calculating Cronbach's alpha and reported satisfactory. Five studies analysed test-retest reliabilities using intra correlation coefficient. Methodological concerns exist. CONCLUSION: The English 19-item, Farsi Persian 19-item, and Vietnamese 19-item versions are recommended for future use in research and practice. Italian 19-item and Malaysian 13-item versions are not recommended to be used in future research and practice. All other versions considered in this review have potential use in future research and practice. Proper procedures for developing a translated version of MOS-SSS and validating the scale are recommended. IMPACT: The review identified quality versions of MOS-SSS to measure social support in future research and practice. The study also indicated methodological issues in current validation studies. Application of the study findings and recommendations can be useful to improve outcome measurement quality and maximize the efficiency of resource use in future research and practice. NO PATIENT OR PUBLIC CONTRIBUTION: This systematic review synthesized the evidence from previous research and did not involve any human participation.

The intergenerational effects of socioeconomic inequality on unhealthy bodyweight.

We study the effects of inherited socioeconomic characteristics on markers of unhealthy bodyweight. Taking Australian microdata from 2007 to 2013, we show that approximately 4% of the variation in outcomes is determined by factors beyond an individual's control, such as their race, gender, and social class. Paternal socioeconomic status is the primary explanatory factor, with those born to more affluent fathers slightly less likely to be overweight in adulthood. Decompositions reveal that only 20%-25% of this effect is attributable to advantaged families exhibiting better health behaviors, which implies that unobserved factors also play an important role. Since diseases associated with unhealthy weight place a major strain on public healthcare systems, our results have implications for the provision of treatment when resources are constrained.

Value for Money of CAR-T Cell Therapy for Patients with Diffuse Large B-cell Lymphoma in China: Evidence from a Cost-Effectiveness Analysis.

OBJECTIVE: This research assesses the cost effectiveness of Axicabtagene ciloleucel (Axi-cel), Tisagenlecleucel (Tis-cel), Relmacabtagene autoleucel (Rel-cel) and Lisocabtagene maraleucel (Lis-cel) against standard of care (SOC) for patients with diffuse large B-cell lymphoma (DLBCL) in the first-line setting (1L), second-line setting (2L) and third-line or later setting (3L+). METHODS: Markov modelling based on a flexible survival model was adopted to evaluate four chimeric antigen receptor T-cell (CAR-T) therapies compared with SOC for patients with diffuse large B-cell lymphoma (DLBCL). The clinical inputs and utility values of the model were derived from the most recent clinical trials and the health care costs from a Chinese provincial clinical center. Costs and quality-adjusted life years (QALYs) were used to derive incremental cost-effectiveness ratios (ICERs) from the Chinese health care system perspective. RESULTS: The ICER of Axi-cel (1L) versus SOC was approximately Chinese Yuan (CNY) 2,125,311 per QALY. The ICER for Axi-cel (2L), Tis-cel (2L) and Liso-cel (2L)) versus SOC in transplant-eligible patients were approximately CNY363,977, CNY32,066,781 and CNY347,746 per quality-adjusted life year (QALY), respectively. The ICER for Liso-cel (2L) versus SOC in transplant-ineligible patients was approximately CNY1,233,972 per QALY. The ICERs for Axi-cel (3L+), Tis-cel (3L+), Rel-cel (3L+) and Liso-cel (3L+) versus SOC were approximately CNY346,009, CNY654,344, CNY280,964 and CNY436,858 per QALY, respectively. In the scenario analysis using mixture cure models, the long-term survival benefit for CAR-T and SOC groups was found higher, and only Rel-cel (3L+) was found to be cost effective. CONCLUSION: Our results demonstrated that CAR-T treatments are not cost effective in any-line settings for DLBCL patients at the WHO-recommended willingness-to-pay threshold (CNY257,241 per QALY) in the base-case analysis. Price reduction of CAR-T therapies is the main approach for lowering ICERs and ensuring that the drug costs are proportional to patient health benefits.

Air pollution and health outcomes: Evidence from Black Saturday Bushfires in Australia.

This paper presents new evidence of the causal effect of air pollution on Australian health outcomes, using the Black Saturday bushfires (BSB) in 2009 as a natural experiment. This event was one of the largest bushfires in Australian history and emitted approximately four million tonnes of CO2 into the atmosphere. We use data from the Household Income and Labour Dynamic Australia (HILDA) panel and compare the health status of individuals who were living in affected and unaffected regions before and after the event. Using a triple differences procedure, we further examine whether a difference in vulnerability to bushfire smoke exists comparing people living in urban or regional areas. We find that ambient air pollution had significant negative effects on health and that the magnitudes were actually larger for individuals residing in urban areas.
