Financial strain and sleep problems in the United Kingdom
Financial strain is a well-established risk factor for poor sleep, yet few studies have examined whether this association varies by race-ethnicity, particularly using longitudinal data. This study investigates the relationship between financial strain and multiple dimensions of sleep, including sleep quality, sleep disturbance, daytime dysfunction, sleep latency, and sleep medication use, across White, Black, Mixed, Asian, and Other racial-ethnic…
Worrying about future finances and sleep problems
BACKGROUND: This study provides the first longitudinal evidence on whether anticipatory financial strain, defined as worrying about one's future finances, is associated with loneliness and sleep problems, whether loneliness mediates the association between anticipatory financial strain and sleep problems, and whether these relationships vary by gender. METHODS: Using Waves 10 and 13 of the United Kingdom Household Longitudinal Study, correspondin…
Disability and life satisfaction
While there is growing interest in the association between disability and diminished life satisfaction, few studies have examined the mechanisms that moderate or mediate this relationship. Informed by the stress process model, this study investigates the moderating and mediating roles of perceived community belonging in the association between different types of disability and life satisfaction. Data were drawn from the 2017–2018 Canadian Communi…
Food Insecurity and Suicidal Ideation
Unpacking the Association Between Food Insecurity and Mental Health Disorders Among Older Adults
ObjectivesPrevious research shows a negative correlation between food insecurity and mental health, but limited exploration exists among older adults. This study examines this association in Canadian adults aged 65 and older, focusing on the mediating roles of perceived life stress and community belonging, and the moderating role of gender.MethodsCross-sectional data from the 2017-2018 Canadian Community Health Survey ( n = 28,044) were analyzed …
The Moderating Role of Perceived Community Belonging in the Association between Food Insecurity and Health and Well-Being
While extensive research has established a link between food insecurity and adverse health and well-being outcomes, less attention has been given to factors that may moderate this relationship. This study examines whether a strong sense of community belonging can buffer the impact of food insecurity on mood and anxiety disorders, poor self-rated mental and general health, and low life satisfaction. Data were drawn from the 2017-2018 Canadian Comm…
Racial/ethnic Variations in the Association Between Financial Strain and Well-Being
Financial strain is a major social stressor that adversely affects well-being, yet few studies have comprehensively examined whether its association differs by race/ethnicity. This study investigates whether the relationship between financial strain and two key outcomes—mental health and life satisfaction—varies across racial/ethnic groups using longitudinal data. Drawing on 13 waves of the United Kingdom Household Longitudinal Survey (UKHLS), sp…
Food Insecurity and Mental Health
Extensive research has demonstrated the negative impact of food insecurity on mental health; however, the mediating and moderating mechanisms underlying this relationship remain underexplored. Using data from the 2022 National Health Interview Survey ( N = 25,703), this study investigates whether sleep problems mediate the relationship between food insecurity and mental health outcomes—specifically depressive and anxiety symptoms—and whether mari…
The Intersection of Weight Status and Weight Perception in Predicting Health-Related Quality of Life (HRQoL) Among Chinese Adolescents
Food insecurity and its association with multiple health outcomes among Indigenous peoples in Canada
The results underscore the detrimental effects of food insecurity on the health of Indigenous peoples in Canada and suggest that culture-based resources, particularly cultural group belonging, play a crucial role in mitigating health disparities
What Happens at Home Does Not Stay at Home
Food Insecurity and Health
Existing research has established the detrimental effects of food insecurity on health. However, understanding of the social conditions that may moderate this relationship remains limited. To address this gap, the study investigates two questions: First, does marital status moderate the association between food insecurity and self-rated health? Second, if such moderation exists, does its impact vary based on gender? Data from the 2017-2018 Canadi…
Exploring the mediating effects of academic performance and self-esteem on the influence of sleep quality on internalizing and externalizing problems among Chinese adolescents
This study examines the associations between sleep quality and internalizing and externalizing problems among Chinese adolescents and investigates whether academic performance and self-esteem function as mediators. Data were obtained from the 2018 wave of the China Family Panel Studies (CFPS), comprising a sample of 1,016 Chinese adolescents aged between 10 and 15 years. We employed multiple mediation models, using Hayes’ PROCESS macro, for data …

Work-to-Family Conflict and Children's Problems with School, Friends, and Health
What is the relationship between work-to-family conflict (WFC) and children's problems with school, friends, and health? And does that association depend on household economic conditions and couple relationship quality? Using four waves of longitudinal data from the Canadian Work, Stress, and Heath Study (2011-2017), the present study finds that-overall-both fathers' and mothers' levels of WFC are associated with elevated levels of children's pro…
Integrating the Eigendecomposition Approach and k-Means Clustering for Inferring Building Functions with Location-Based Social Media Data
Understanding the relationship between human activity patterns and urban spatial structure planning is one of the core research topics in urban planning. Since a building is the basic spatial unit of the urban spatial structure, identifying building function types, according to human activities, is essential but challenging. This study presented a novel approach that integrated the eigendecomposition method and k-means clustering for inferring bu…
Financial Strain and Psychological Distress
Analyzing three waves of the Canadian Work Stress and Health Study with cross-lagged models, we asked: (1) How do two distinct directions of strain in the work-family interface—work-to-family conflict and family-to-work conflict—mediate the relationship between financial strain and psychological distress? and (2) Is reverse causality a possibility in these dynamics? Our results indicate that work-to-family conflict at Wave 2 mediates the relation…

Economic Insecurity among Gay and Bisexual Men
Although a sizeable body of research has examined the labor market outcomes for sexual minority men, suggesting that gay and bisexual men earn less than their heterosexual counterparts, fewer studies have addressed whether any apparent earnings disadvantages for sexual minority men extend to economic insecurity more broadly. Using 1991–2016 U.S. General Social Survey (GSS) data, we examine three measures of economic insecurity—household income, p…
