“…We hypothesize that the positive association between ECTC eligibility and adult overall health was likely mediated through associated reductions in poverty and financial hardship . Ample research supports this association, with reductions in poverty associated with reduced mortality, disability, heart disease, and diabetes .…”

“…Half of the total value was dispensed in monthly payments from July 15 to December 31 of 2021. These monthly payments were associated with a temporary 40–percentage point reduction in the rate of poverty in households with children . Unlike prior iterations of the Child Tax Credit, these payments were fully refundable, meaning that all low-income households were eligible to receive the full value of the credit as a direct deposit or check .…”

ImportanceThe 2021 Expanded Child Tax Credit (ECTC) provided families with children monthly payments from July 2021 to December 2021. The association of this policy with adult health is understudied.ObjectiveTo examine changes in adult self-reported health and household food security before and during ECTC monthly payments.Design, Setting, and ParticipantsThis repeated cross-sectional study used multivariable regression with a difference-in-differences estimator to assess adult health and food security for 39 479 respondents to the National Health Interview Survey (January 2019 to December 2021) before vs during monthly payments. Analyses were stratified by income to focus on low-income vs middle-income and upper-income households.ExposureEligibility for ECTC monthly payments from July 2021 to December 2021.Main Outcomes and MeasuresOverall self-reported adult health and household food security as binary outcomes (excellent or very good health vs good, fair, or poor health; food secure vs food insecure).ResultsIn this nationally representative cross-sectional study of 39 479 US adults (mean [SD] age, 41.0 [13.0] years; 7234 [21.7%] Hispanic, 321 [0.9%] non-Hispanic American Indian/Alaska Native, 2205 [5.7%] non-Hispanic Asian, 5113 [13.7%] non-Hispanic Black, and 23 704 [55.8%] White individuals), respondents were predominantly female (21 511 [52.4%]), employed (33 035 [86.7%]), and married (19 838 [55.7%]). Before disbursement of ECTC monthly payments, 7633 ECTC-eligible adults (60.1%) reported excellent or very good health, and 10 950 (87.8%) reported having food security. Among ECTC-ineligible adults, 10 778 (54.9%) reported excellent or very good health and 17 839 (89.1%) reported food security. Following disbursement of monthly payments, ECTC-eligible adults experienced a 3.0 percentage point (pp) greater adjusted increase (95% CI, 0.2-5.7) in the probability of reporting excellent or very good health compared with ECTC-ineligible adults. Additionally, ECTC-eligible adults experienced a 1.9 pp greater adjusted increase (95% CI, 0.1-3.7) in the probability of food security than ECTC-ineligible adults. In income-stratified analyses, the association between ECTC eligibility and overall health was concentrated among middle-income and upper-income households (3.7-pp increase in excellent or very good health; 95% CI, 0.5-6.9). Conversely, the association between ECTC eligibility and food security was concentrated among low-income adults (3.9-pp increase in food security; 95% CI, 0-7.9).Conclusions and RelevanceThe results of this cross-sectional study suggest that monthly ECTC payments were associated with improved adult overall health and food security. Cash transfer programs may be effective tools in improving adult health and household nutrition.

In this study, we investigate the use of representation learning techniques for solving complex problems represented as graphs. To this end, we propose a novel method for learning graph representations called Inferring Embedded Email Roles (IEER). Our method generates low-dimensional vectorized features by acquiring local structural information for each vertex in the graph. Unlike existing approaches that have focused on incorporating various graph attributes, our method takes a unique approach to improving the performance of the base framework, EMBedding Email-based Roles (EMBER). This research aims to understand the effectiveness of an embedding technique for generating graph representations and its suitability for replacing the base framework technique. We identify an embedding technique that significantly improves the performance of EMBER, resulting in a 94\% accuracy improvement using the Permutation Invariant technique, which has been shown to outperform matrix factorization techniques in capturing structural behaviors. This technique has been shown to outperform matrix factorization techniques in dealing with structural behaviors. Additionally, our method is scalable and linear concerning the number of vertices in the graph.
