Objective

To examine the association between the use of community-based social assistance programs (CB-SAPs) and the reduction of household food insecurity among de novo food-aid seekers in Quebec, Canada.

Study design

Prospective Cohort Study.

Methods

A longitudinal observational study was conducted using a sample of 915 newly registered food-aid seekers in Quebec's food banks from The Pathways cohort study (2018–2020). The outcome was any reduction in the severity of Household Food Insecurity. Exposures included three CB-SAPS:1) using food donations, 2) using food-management related CB-SAPs (other than food donations), and 3) using CB-SAPs unrelated to food. We used Longitudinal Targeted Maximum Likelihood Estimation (LTMLE) to estimate the Relative Risk (RR) and LTMLE for working Marginal Structural Models to estimate Average Additive Treatment Effects (ATE) of the relationship between the use of CB-SAPs and Household Food Insecurity.

Results

The use of CB-SAPs showed a trend towards reduction of Household Food Insecurity. Compared to households using exclusively food banks at baseline, households with multiple-food-acquisition (Multiple AFS) health-promoting practices were more likely to reduce (in the relative scale) Household Food Insecurity by using: food donations (RR: 1.30; 95 %CI:1.01, 1.60); food-management related CB-SAPs (RR: 1.28; 95 %CI:1.03, 1.58); and CB-SAPs unrelated to food (RR: 1.33; 95 %CI:1.03, 1.62). Multiple AFS showed a reduction in the Household Food Insecurity (absolute) scale, especially among food-management related CB-SAPs users (ATE: −0.24; 95 %CI: 0.43, −0.04).

Conclusions

CB-SAPs use contributes to reducing Household Food Insecurity. This contribution varies depending on the food-acquisition health-promoting practices of food-aid seeker households.
目的研究加拿大魁北克省新寻求粮食援助的人使用社区社会援助计划（CB-SAPs）与减少家庭粮食不安全之间的关系。研究设计前瞻性队列研究。方法对魁北克食品银行915名新登记的食品援助寻求者进行纵向观察研究，样本来自Pathways队列研究（2018-2020）。结果是家庭粮食不安全的严重程度有所减轻。暴露包括三种CB-SAPS:1)使用食品捐赠，2)使用与食品管理相关的CB-SAPS（食品捐赠除外），以及3)使用与食品无关的CB-SAPS。我们使用纵向目标最大似然估计（LTMLE）来估计相对风险（RR），并使用LTMLE进行边际结构模型来估计cb - sap使用与家庭粮食不安全之间关系的平均加性处理效应（ATE）。结果cb - sap的使用呈现出减少家庭粮食不安全的趋势。与仅在基线时使用食物银行的家庭相比，采用多种食物获取（Multiple AFS）健康促进做法的家庭更有可能（在相对规模上）通过以下方式减少家庭粮食不安全：食物捐赠（相对危险度：1.30；95%可信区间：1.01,1.60）；与食品管理相关的cb - sap (RR: 1.28; 95% CI:1.03, 1.58)；与食物无关的cb - sap （RR: 1.33; 95% CI:1.03, 1.62）。多个AFS显示家庭粮食不安全（绝对）规模减少，特别是在与食品管理相关的cb - sap用户中（ATE: - 0.24; 95% CI: 0.43, - 0.04）。结论scb - saps的使用有助于减少家庭粮食不安全。这一贡献因寻求粮食援助的家庭获取粮食的促进健康做法而异。

The global prevalence of single-person households is rapidly increasing. However, emerging evidence indicates that individuals living alone are at greater risk of experiencing depressive symptoms. Therefore, this study aims to investigate the mediating roles of dietary quality and eating companionship in the relationship between household type and depressive symptoms. Data from the 2016, 2018, and 2020 Korean National Health and Nutrition Examination Survey were analyzed, comprising 13,357 participants aged ≥20 years. Depressive symptoms were measured using the Patient Health Questionnaire-9 (PHQ-9), dietary quality with the Korean Healthy Eating Index, and eating companionship through the frequency of eating alone. Logistic regression and causal mediation analyses were performed, adjusting for demographic and socioeconomic variables. Sampling weights were applied to ensure national representativeness. Individuals in single-person households exhibited significantly higher odds of experiencing mild-to-severe (PHQ-9 ≥5) and moderate-to-severe (PHQ-9 ≥10) depressive symptoms compared with those in multi-person households across all age groups. Lower dietary quality and a higher frequency of eating alone were significantly associated with increased depressive symptoms. Causal mediation analysis indicated that dietary quality accounted for 8.4 % and 10.7 % of the associations with mild-to-severe and moderate-to-severe depressive symptoms, respectively, while the frequency of eating alone mediated 30.3 % and 38.5 % of these associations. Poor dietary quality and frequent solitary eating mediate the association between living alone and depressive symptoms. Public health interventions that encourage healthier eating habits and promote shared mealtimes may help alleviate depressive symptoms among the increasing population of individuals living alone.
全球单身家庭的流行正在迅速增加。然而，越来越多的证据表明，独居者出现抑郁症状的风险更大。因此，本研究旨在探讨饮食质量和饮食陪伴在家庭类型与抑郁症状关系中的中介作用。分析了2016年、2018年和2020年韩国国民健康与营养调查的数据，其中包括13357名年龄≥20岁的参与者。通过患者健康问卷-9 （PHQ-9）、韩国健康饮食指数的饮食质量和单独用餐频率的饮食陪伴来测量抑郁症状。进行了逻辑回归和因果中介分析，调整了人口统计和社会经济变量。采用加权抽样，以保证全国代表性。在所有年龄组中，与多人家庭相比，单人家庭的个体出现轻至重度（PHQ-9≥5）和中度至重度（PHQ-9≥10）抑郁症状的几率显著高于多人家庭。较低的饮食质量和较高的单独进食频率与抑郁症状的增加显著相关。因果中介分析表明，饮食质量分别占轻度至重度和中度至重度抑郁症状关联的8.4%和10.7%，而单独进食的频率分别占30.3%和38.5%。不良的饮食质量和频繁的单独进食介导了独居和抑郁症状之间的关联。鼓励健康饮食习惯和促进共享用餐时间的公共卫生干预措施可能有助于减轻越来越多的独居者的抑郁症状。

Background

Most caregiver health studies rely on observational data and traditional regression methods, which fail to account for time-varying confounding, limiting causal inference. This analysis uses inverse probability weighting (IPW) to appropriately account for time-varying confounding in caregiving-depression relationship.

Methods

Using seven waves (2004–2019) of the Survey of Health, Ageing and Retirement in Europe, we estimated the effect of caregiving on probable depression (having 4+ symptoms) comparing daily and some caregiving to no caregiving. We accounted for censoring and potential measured confounding by time-fixed covariates (gender, number of children, country, and education) and time-varying covariates (age, employment, marital status, income, physical limitations, psychiatric medication, receiving help, previous caregiving, and previous depression) using IPCW and IPTW. The product of the two weights was applied to a marginal structural model to obtain the causal estimand on the prevalence difference scale. Confidence intervals were derived from bootstrapping.

Results

Among 36 346 participants and 67 800 person-waves, compared to no caregiving in the last year, daily caregiving was associated with a 6.7 percentage point (95 % CI: 4.8 %, 8.6 %) increase in the prevalence of probable depression, after accounting for time-fixed and time-varying covariates. Some caregiving was not associated with probable depression (PD = 0.5, 95 % CI = −0.8 %, 1.8 %).

Conclusions

Our results support existing findings that high levels of caregiving may increase the prevalence of probable depression, while lower levels of caregiving do not. Accurate documentation of the relationship between caregiving and health outcomes is foundational in creating evidence-based policies to support healthy aging.
大多数护理人员健康研究依赖于观察数据和传统的回归方法，这些方法无法解释时变混杂，限制了因果推断。本分析使用逆概率加权（IPW），以适当地说明时变的混杂在照顾抑郁的关系。方法利用欧洲健康、老龄化和退休调查的七波（2004-2019），通过比较每天和一些护理与不护理，估计护理对可能的抑郁症（有4+症状）的影响。我们使用IPCW和IPTW，通过时间固定的协变量（性别、子女数量、国家和教育）和时间变化的协变量（年龄、就业、婚姻状况、收入、身体限制、精神药物、接受帮助、以前的照顾和以前的抑郁症）来解释审查和潜在的测量混淆。将这两个权重的乘积应用于一个边际结构模型，得到患病率差异尺度上的因果估计。置信区间由自举推导而来。结果在36346名参与者和67800名患者中，与去年没有护理相比，在考虑了时间固定和时变协变量后，每天护理与可能的抑郁症患病率增加6.7个百分点（95% CI: 4.8%, 8.6%）相关。一些护理与可能的抑郁无关（PD = 0.5, 95% CI = - 0.8%, 1.8%）。结论高水平的照顾可能增加抑郁症的患病率，而低水平的照顾不会增加抑郁症的患病率。准确记录护理与健康结果之间的关系，是制定支持健康老龄化的循证政策的基础。

Tobacco consumption during pregnancy poses significant risks to maternal and neonatal health. In 2011, Mexico implemented a large nationwide increase in tobacco excise taxes. Because the policy was applied uniformly across the country and detailed smoking data are limited, identifying causal effects is particularly challenging. Using comprehensive vital statistics records on all singleton live births in Mexico, we apply a regression discontinuity in time design to evaluate the short-term impact of a 250% increase in the excise tax on tobacco products on newborn health outcomes. Our findings provide evidence of moderate short-term increases in birth weight after the tax hike. Although the effects diminish over time and show sensitivity to model specification, they may indicate potential long-term public health benefits. This study provides new evidence on the effects of nationwide tobacco tax increases on birth outcomes in middle-income countries.
怀孕期间吸烟对孕产妇和新生儿健康构成重大风险。2011年，墨西哥在全国范围内大幅提高了烟草消费税。由于该政策在全国范围内统一实施，详细的吸烟数据有限，因此确定因果关系尤其具有挑战性。利用墨西哥所有单胎活产的综合生命统计记录，我们采用时间设计中的回归不连续来评估烟草制品消费税增加250%对新生儿健康结果的短期影响。我们的研究结果提供了增税后出生体重短期适度增加的证据。虽然影响随着时间的推移而减弱，并且对模型规格表现出敏感性，但它们可能表明潜在的长期公共健康益处。这项研究为中等收入国家全国范围内增加烟草税对出生结果的影响提供了新的证据。

Employer-sponsored health insurance (ESI) is a primary source of health coverage for working-aged adults in the U.S. Although most larger employers offer ESI, 46% of U.S. workers are employed by small businesses, which offer ESI at less than half the rate of large businesses. We extend prior research by examining detailed racial/ethnic ownership of small businesses and trends in offering ESI throughout the rollout of the Affordable Care Act's (ACA) small business policies. We use restricted data from the Census Bureau's 2012 Survey of Business Owners and the 2014–2016 waves of the Annual Survey of Entrepreneurs. Binary logistic regression allows us to examine whether the racial/ethnic composition of the business owners is associated with offering ESI, within each of the four waves of data. Finally, we plot the fitted percentage of small businesses that offer ESI across time and racial/ethnic ownership status, while adjusting for owner and firm characteristics. The majority of small businesses do not offer ESI. Further, disparities are substantial. In 2012, just 41% of White-owned small businesses offer ESI, compared to 26% of Black-, 26% of Asian-, and 23% of Hispanic-owned small businesses. These disparities fail to improve across years when the ACA incentives were implemented. Policies that recognize and address differences in ESI among small businesses, especially among Black-, Asian-, and Hispanic-owned small businesses, could strengthen healthcare systems and access to care in communities where minority-owned small businesses and their employees are located.
雇主赞助的健康保险（ESI）是美国工作年龄成年人健康保险的主要来源。尽管大多数大雇主都提供ESI，但46%的美国工人受雇于小企业，而小企业提供ESI的比例不到大企业的一半。我们通过详细研究小企业的种族/民族所有权以及在《平价医疗法案》（ACA）小企业政策推出过程中提供ESI的趋势，扩展了先前的研究。我们使用了来自人口普查局2012年企业主调查和2014-2016年企业家年度调查的有限数据。二元逻辑回归使我们能够在四波数据中的每一波中检查企业主的种族/民族构成是否与提供ESI相关。最后，我们绘制了跨时间和种族/民族所有权状态提供ESI的小企业的拟合百分比，同时对所有者和公司特征进行了调整。大多数小企业不提供ESI。此外，差距很大。2012年，白人拥有的小企业中只有41%提供ESI服务，而黑人、亚洲人和西班牙裔拥有的小企业中这一比例分别为26%、26%和23%。这些差距在ACA激励措施实施后的几年里都没有改善。认识到并解决小型企业（尤其是黑人、亚洲人和西班牙裔拥有的小型企业）ESI差异的政策，可以加强少数族裔拥有的小型企业及其员工所在社区的医疗保健系统和获得医疗服务的机会。

Current studies suggest the intergenerational transmission of educational advantages is bidirectional over the life course. However, results from causal analysis studies do not consistently support the beneficial effect of adult children's education on aging parents' health.

Using the 2016 and 2018 China Family Panel Studies data and instrumental variable estimation, we examine the effect of adult children's education on parents' health and systematically explore its heterogeneity and underlying mechanisms.

The mechanism analyses results suggest that adult children's education may enhance parents' health through both stress-based pathways (i.e., family economic hardship) and resource-based pathways (i.e., emotional support from children, housework support from parents, and improving parents' access to the resources), but not via the analyzed health habits. Our findings suggest that promoting children's education may improve parents' health over the life course, especially at least graduating from middle school. Our findings imply that prioritizing basic education policy in less developed regions, and providing buffers for economic stressors or enhancing daily intergenerational interactions within families are important for healthy aging in developing societies.
目前的研究表明，教育优势的代际传递在一生中是双向的。然而，因果分析研究的结果并不一致地支持成年子女教育对老年父母健康的有益影响。相互矛盾的证据表明一种复杂的关系，这种关系可能是非线性的，或者只在某些情况下突出，或者可以用特定的途径来解释，但仍未被探索。利用2016年和2018年中国家庭面板研究数据和工具变量估计，我们研究了成年子女教育对父母健康的影响，并系统地探讨了其异质性和潜在机制。本研究利用两阶段最小二乘（IV/2SLS）工具变量估计发现，成年子女教育显著改善了中老年父母的健康状况，但这种影响可能是非线性的。当成年子女的受教育程度超过中学教育水平时，健康的有益代际传递可能略有减弱。成年子女受教育程度对父母健康的影响在较不发达地区、较年轻的父母以及与成年子女同住或受教育程度低于成年子女的父母中可能更为显著。机制分析结果表明，成年子女教育可以通过压力基础途径（即家庭经济困难）和资源基础途径（即儿童的情感支持、父母的家务支持和改善父母对资源的获取）增强父母的健康，但不能通过所分析的健康习惯来增强父母的健康。我们的研究结果表明，促进儿童教育可能会改善父母在整个生命过程中的健康，尤其是至少中学毕业。我们的研究结果表明，在欠发达地区优先考虑基础教育政策，为经济压力提供缓冲或加强家庭内部的日常代际互动，对于发展中社会的健康老龄化至关重要。

Background

Japan experienced a substantial decrease in suicide rates in the 2010s. During this period, the “Supporting the Self-Reliance of Persons in Need” program was initiated to target individuals struggling to meet basic needs. The program provides personalized consultations and subprograms that address the residence issues, necessities, employment needs, and household finance management problems. This study evaluates whether this program is related to the decline in Japan's suicide rates in the 2010s.

Methods

The first analysis employs a difference-in-differences approach, using the monthly suicide rates in 815 cities across Japan from 2009 to 2015. Policy exposure refers to the period after pilot programs were introduced in cities between 2013 and 2015. The second analysis examines whether the number of subprograms application counts is associated with the suicide rates by fiscal year.

Results

The introduction of self-reliance support in cities is related to a monthly reduction of 0.066 and 0.041 in suicide rates among men and women, respectively. The associations are found among the population under 60 years, particularly strong for males and the middle-aged. The second analysis suggests that the employment training program shows the strongest association with lower suicide rates. An additional employment training application per 100,000 population is associated with a 0.256 reduction for males and 0.169 for females in the annual suicide rates.

Conclusions

The introduction of self-reliance support is associated with reduced suicide rates, mainly among males and the middle-aged. The employment training subprogram demonstrates the strongest association with lower suicide rates.
日本在2010年代经历了自杀率的大幅下降。在此期间，启动了“支持有需要的人自力更生”计划，以满足基本需求的个人为目标。该方案提供个性化咨询和子方案，解决居住问题、必需品、就业需求和家庭财务管理问题。这项研究评估了这个项目是否与2010年代日本自杀率的下降有关。第一个分析采用了差异中的差异方法，使用了2009年至2015年日本815个城市的月度自杀率。政策曝光指的是2013年至2015年在城市引入试点项目后的一段时间。第二项分析考察了子项目申请数量是否与财政年度的自杀率有关。结果在城市引入自力更生支持与男性和女性自杀率每月分别下降0.066和0.041有关。这些关联在60岁以下的人群中发现，尤其是男性和中年人。第二项分析表明，就业培训计划与较低的自杀率之间的联系最为密切。每10万人中增加一份就业培训申请，每年的自杀率男性降低0.256，女性降低0.169。结论自力更生支持的引入与自杀率的降低有关，主要发生在男性和中年人之间。就业培训子项目显示出与较低自杀率的最强关联。

Background

The COVID-19 pandemic has significantly affected the mental health of young adults, particularly those facing socioeconomic hardship. Although psychological distress appears to be declining in the general population post-pandemic, vulnerable subgroups remain at elevated risk. Network analysis offers a transdiagnostic approach to understanding the dynamic interplay of depressive and anxiety symptoms over time.

Methods

We conducted a repeated cross-sectional study among socioeconomically disadvantaged young adults in 2020 (T1) and 2024–2025 (T2). Depressive and anxiety symptoms were assessed using the PHQ-9 and GAD-7. Symptom networks were estimated using Gaussian Graphical Models with EBICglasso. The Network Comparison Test (NCT) evaluated changes in network structure and symptom centrality. Clustering analysis was performed to explore the reorganization of symptom groupings over time.

Results

Mean scores increased significantly between T1 (n = 960) and T2 (n = 380) for both depression (PHQ-9: 9.43 to 11.35, p < 0.001) and anxiety (GAD-7: 6.3 to 8.14, p < 0.001). Suicidal ideation nearly doubled (25.9 %–42.9 %, p < 0.001). Network analysis revealed stronger interconnections between depressive and anxiety symptoms at T2. Anxiety symptoms (particularly GAD3, GAD2, and GAD1) became more central, while suicidal ideation shifted from a depression-specific cluster to one integrating anxiety symptoms. Clustering analysis supported a progressive integration of depressive and anxiety domains.

Conclusion

Our findings suggest an evolving post-pandemic psychopathological network, with anxiety symptoms becoming increasingly central and closely linked to suicidal ideation. These results underscore the need for targeted interventions addressing both depression and anxiety, particularly among socioeconomically vulnerable young adults, to more effectively reduce suicide risk in this population.
2019冠状病毒病大流行严重影响了年轻人的心理健康，特别是那些面临社会经济困难的年轻人。虽然大流行后一般人群的心理困扰似乎有所减少，但弱势亚群体的风险仍然较高。网络分析提供了一种跨诊断的方法来理解抑郁和焦虑症状随时间的动态相互作用。方法我们在2020年（T1）和2024-2025年（T2）对社会经济条件较差的年轻人进行了重复横断面研究。使用PHQ-9和GAD-7评估抑郁和焦虑症状。使用EBICglasso的高斯图形模型估计症状网络。网络比较测试（NCT）评估网络结构和症状中心性的变化。进行聚类分析以探索症状分组随时间的重组。结果在T1 （n = 960）和T2 （n = 380）之间，抑郁（PHQ-9: 9.43 ~ 11.35, p < 0.001）和焦虑（GAD-7: 6.3 ~ 8.14, p < 0.001）的平均得分均显著升高。自杀意念几乎翻倍（25.9% - 42.9%,p < 0.001）。网络分析显示T2时抑郁和焦虑症状之间有更强的相互联系。焦虑症状（尤其是GAD3、GAD2和GAD1）变得更为中心，而自杀意念从抑郁症特异性集群转移到一个整合焦虑症状的集群。聚类分析支持抑郁和焦虑领域的渐进式整合。结论：我们的研究结果表明，大流行后的精神病理网络不断发展，焦虑症状变得越来越重要，与自杀意念密切相关。这些结果强调了针对抑郁和焦虑进行有针对性干预的必要性，特别是在社会经济脆弱的年轻人中，以更有效地降低这一人群的自杀风险。

With the increasing penetration of social networking sites into daily life, college students are engaging more frequently in body-related expressions and interactions on these platforms, referred to as social networking site body talk. Although previous studies have indicated potential links between social networking sites, body image, and health behaviors, the relationship between social networking sites body talk and physical activity, as well as the underlying mechanisms, remain unclear. Therefore, this study focuses on examining the relationship between social networking sites body talk and physical activity among college students, and tests the mediating role of upward appearance comparison and the moderating role of self-compassion. Empirical analysis was conducted on data collected from 1189 Chinese college students (604 males and 585 females). The results showed that social networking site body talk was significantly and positively associated with physical activity. Further analysis revealed that upward appearance comparison mediated the association between social networking sites body talk and physical activity. Moreover, this mediating effect was moderated by levels of self-compassion, with the mediation being more pronounced among individuals with higher self-compassion. The findings of this study enrich the literature on social media and health behaviors, and have important practical implications for designing interventions aimed at promoting physical activity among college students.
随着社交网站越来越多地渗透到日常生活中，大学生在这些平台上进行与身体相关的表达和互动的频率越来越高，被称为社交网站身体对话。虽然以前的研究已经表明社交网站、身体形象和健康行为之间存在潜在的联系，但社交网站身体谈话和身体活动之间的关系以及潜在的机制仍然不清楚。因此，本研究主要考察社交网站肢体语言与大学生体育活动的关系，并检验向上外表比较的中介作用和自我同情的调节作用。本文对1189名中国大学生（男604人，女585人）的数据进行了实证分析。结果表明，社交网站身体谈话与身体活动显著正相关。进一步的分析表明，向上的外表比较介导了社交网站、肢体语言和体育活动之间的关联。此外，这种中介效应受自我同情水平的调节，在自我同情水平高的个体中，这种中介作用更为明显。本研究的发现丰富了关于社交媒体和健康行为的文献，并对设计旨在促进大学生体育活动的干预措施具有重要的实际意义。
