Longitudinal patterns of companion animals in families with children during the COVID-19 pandemic: Findings from the Adolescent Brain Cognitive Development (ABCD) Study®.

Pet acquisition purportedly increased during the COVID-19 pandemic with individuals acquiring pets during periods of social isolation. Families with children experienced unique challenges during the COVID-19 pandemic, balancing childcare, remote schooling, and other needs and therefore patterns of pet acquisition and loss may differ from the broader population. The goal of this study was to understand patterns of pet ownership within families with adolescents during the pandemic to help identify areas for improved support and programmatic recommendations. Using self-reported survey data from a sample of 7,590 American adolescents from the Adolescent Brain Cognitive Development (ABCD) Study® COVID Survey, we found no evidence for large-scale changes in pet acquisition or relinquishment during the first year of the pandemic for families with adolescents in the U.S. Future research should explore the effects of pet acquisition and pet loss on families with adolescents and what resources are needed to support pet ownership during stressors such as the COVID-19 pandemic.

Longitudinal Associations Between Pet Relationship Quality and Socio-Emotional Functioning in Early Adolescence.

Adolescence is a key developmental period for socio-emotional skills, and companion animal relationships may be one potential source of emotional support and resilience during this time. This study used longitudinal data from 940 pet-owning adolescents, collected over four time points, from youth in the Northeastern United States. We assessed whether pet relationship quality (indexed by relationship satisfaction, companionship, and emotional disclosure) predicted trajectories of loneliness, social anxiety, and depression. Results indicated that high satisfaction with a pet relationship was associated with more favorable trajectories, but companionship (i.e., regarding frequency of interacting with the pet) was not related significantly to socio-emotional functioning. High levels of disclosure to a pet were linked with less favorable trajectories for loneliness and depression, but not related to social anxiety. These results suggest that a pet relationship can, in some cases, be associated positively with socio-emotional development, but that there is significant complexity in these associations. Families, educators, and practitioners should take a nuanced approach to understanding individual adolescent-pet relationships as a contextual asset for specific youth.

Competitive Foods' Nutritional Quality and Compliance with Smart Snacks Standards: An Analysis of a National Sample of U.S. Middle and High Schools.

Snacks and beverages are often sold in addition to meals in U.S. schools ("competitive foods"), but their current nutritional quality and compliance with national Smart Snacks standards are unknown. This study assessed competitive foods in a national sample of 90 middle and high schools. Differences in compliance by school characteristics were measured using mixed methods analysis of variance. Overall, 80% of the schools in the sample sold competitive foods; but they were less commonly available in schools with universal free school meal (UFSM) policies. A total of 840 unique products were documented and, on average, 75% were compliant with Smart Snacks standards. A total of 56% aligned with recommended added sugar limits (<10% of calories); and 340 unique products (40%) aligned with both sugar and Smart Snacks standards. Approximately one-fifth of competitive foods contained synthetic dyes, and 31% of beverages contained artificial sweeteners. Smart Snacks standards compliance was greater when competitive foods were overseen by food service departments, in comparison with others (e.g., principals, student organizations, or outside vendors [77% vs. 59% compliance; p = 0.003]). Therefore, district wellness policies should consider requiring food service departments to oversee competitive foods. Federal and state policies should limit added sugars, artificial sweeteners, and synthetic dyes. This appears to be highly feasible, given the substantial number of products that meet these criteria. UFSM policies should also be considered to support healthier school meal environments more broadly.

Companion animals and the relationship between peer victimization and emotion regulation in youth.

Peer victimization can negatively impact emotion regulation in youth and is associated with harmful mental health outcomes. One protective factor against the impacts of peer victimization is a strong attachment to family and positive peer relationships. Given that pets are commonly seen as family members and that youth report turning to their pet for emotional comfort, companion animals could provide an avenue of support for youth experiencing victimization. A geographically diverse sample of 5725 adolescents in the United States from the Adolescent Brain Cognitive Development (ABCD) Study® was used to explore whether the relationship between peer victimization and emotion regulation was moderated by whether a pet lives in the home. Having a pet in the home did not moderate the relationship between peer victimization and emotion regulation; however, mean-level differences were present across types of household pet (i.e., youth with no pets, youth with at least one dog, and youth with non-dog pets). Participants who did not live with a companion animal showed higher levels of both maladaptive emotion regulation (expressive suppression) and adaptive emotion regulation (cognitive reappraisal), suggesting that having a pet might lower overall emotion regulation pathways regardless of adaptive directionality. Relational victimization was a significant predictor of expressive suppression regardless of whether there was a pet in the home, although overt victimization was not a predictor of either kind of emotion regulation. This research demonstrates the complex nature of human-animal relationships and suggests more research is needed to understand the nuanced relationship between pets, peer victimization, and emotion regulation.

Companion animals and profiles of peer social behavior in adolescence.

INTRODUCTION: Relationships with companion animals have been associated with higher levels of prosocial behavior and lower levels of socioemotional difficulties for children and adolescents. Companion animals may be supportive of developing prosocial behavior in youth through practice with positive social interactions and the development of empathy and reciprocity skills. The goal of this study was to use a person-centered approach to investigate if living with a pet (including pet species) is associated with profiles of adolescent peer social behaviors (i.e., prosocial, aggressive), and size of their peer network. METHODS: This study used data from the Adolescent Brain Cognitive Development (ABCD) Study®, a large, nationally representative data set of American adolescents. RESULTS: In a cross-sectional sample of 5218 adolescents, we found that youth clustered into four different distinct profiles of peer social behavior. Female youth living with dogs were less likely to be in the High Aggression profile as compared to youth without pets or youth with other types of pets. However, having a pet was not associated with whether youth were in the profiles characterized by prosocial behaviors or size of peer network. CONCLUSIONS: Overall, future research should explore how gender intersects with companion animal interactions-both in terms of frequency of interactions as well as relationship quality/emotional attachment-as well as examine these relationships over time to assess causality.

Default mode network functional connectivity strength in utero and the association with fetal subcortical development.

The default mode network is essential for higher-order cognitive processes and is composed of an extensive network of functional and structural connections. Early in fetal life, the default mode network shows strong connectivity with other functional networks; however, the association with structural development is not well understood. In this study, resting-state functional magnetic resonance imaging and anatomical images were acquired in 30 pregnant women with singleton pregnancies. Participants completed 1 or 2 MR imaging sessions, on average 3 weeks apart (43 data sets), between 28- and 39-weeks postconceptional ages. Subcortical volumes were automatically segmented. Activation time courses from resting-state functional magnetic resonance imaging were extracted from the default mode network, medial temporal lobe network, and thalamocortical network. Generalized estimating equations were used to examine the association between functional connectivity strength between default mode network-medial temporal lobe, default mode network-thalamocortical network, and subcortical volumes, respectively. Increased functional connectivity strength in the default mode network-medial temporal lobe network was associated with smaller right hippocampal, left thalamic, and right caudate nucleus volumes, but larger volumes of the left caudate. Increased functional connectivity strength in the default mode network-thalamocortical network was associated with smaller left thalamic volumes. The strong associations seen among the default mode network functional connectivity networks and regionally specific subcortical volume development indicate the emergence of short-range connectivity in the third trimester.

Changes in Adults' Eating Behaviors During the Initial Months of the COVID-19 Pandemic: A Narrative Review.

Factors such as regulations and health concerns shifted daily habits, including eating behaviors, during the early months of the coronavirus disease 2019 (COVID-19) pandemic. This comprehensive narrative review synthesizes research on eating behavior changes during the early months of the pandemic (February to June 2020), including changes in amount, rate, and timing of food consumption, types and healthfulness of foods consumed, the occurrence of other specified eating behaviors (eg, restrained eating or binging), and reasons for eating (eg, stress or cravings), among adults. A literature search using three EBSCOhost databases and Google Scholar was conducted to identify relevant articles made available in 2020. A total of 71 articles representing 250,715 individuals from more than 30 countries were reviewed. Findings show eating behaviors changed little during the early COVID-19 pandemic for most participants. Among those whose eating behaviors changed, increases in both intake and frequency of eating meals and snacks were more common than decreases. Findings on timing of eating and healthfulness of food consumed showed mixed results. However, when changes occurred in the type of food consumed, increases were more common for snacks, homemade pastries, white bread/pasta, legumes, and fruits/vegetables; decreases were more common for meats, seafood/fish, frozen foods, fast food, dark breads/grains, and dark leafy green vegetables. During the pandemic, binging, uncontrolled eating, and overeating increased, meal skipping decreased, and restrictive eating had mixed findings. Changes in factors such as emotions and mood (eg, depression), cravings, and environmental factors (eg, food insecurity) were related to changes in eating behaviors. Findings can inform clinical practitioners in efforts to mitigate disruptions to normal, healthy eating patterns among adults both in and outside of global health catastrophes.

Associations between Pet Care Responsibility, Companion Animal Interactions, and Family Relationships during COVID-19.

For families with children during the COVID-19 pandemic, it is crucial to explore how both youth and parents view their roles with regard to the shared caretaking of pets. While most human-animal interaction studies examine adult or early childhood samples, our focus was on adolescent development. We present findings from a U.S. based mixed-method study of adolescent surveys and parent interviews regarding pet care responsibility. As part of an ongoing longitudinal study, we analyzed survey data from 567 pet-owning adolescents and a subset of 356 dog owning adolescents aged 10-17 as well as 31 in-depth interviews with parents of adolescents from the same study. Higher reported pet caretaking responsibilities was significantly associated with a preference for spending time with pets when stressed and improved family relationships during the COVID-19 pandemic for both pet owners and dog owners. For dog owners only, increased levels of responsibility for the pet was significantly associated with a higher likelihood of identifying as a pet owner. Qualitative findings showcase the range of parental expectations and adolescent initiative around pet caretaking. Our study highlights the continued importance of pet companionship during the adolescent years as they develop their identities as responsible pet owners.

Semi-automatic segmentation of the fetal brain from magnetic resonance imaging.

Background: Volumetric measurements of fetal brain maturation in the third trimester of pregnancy are key predictors of developmental outcomes. Improved understanding of fetal brain development trajectories may aid in identifying and clinically managing at-risk fetuses. Currently, fetal brain structures in magnetic resonance images (MRI) are often manually segmented, which requires both time and expertise. To facilitate the targeting and measurement of brain structures in the fetus, we compared the results of five segmentation methods applied to fetal brain MRI data to gold-standard manual tracings. Methods: Adult women with singleton pregnancies (n = 21), of whom five were scanned twice, approximately 3 weeks apart, were recruited [26 total datasets, median gestational age (GA) = 34.8, IQR = 30.9-36.6]. T2-weighted single-shot fast spin echo images of the fetal brain were acquired on 1.5T and 3T MRI scanners. Images were first combined into a single 3D anatomical volume. Next, a trained tracer manually segmented the thalamus, cerebellum, and total cerebral volumes. The manual segmentations were compared with five automatic methods of segmentation available within Advanced Normalization Tools (ANTs) and FMRIB's Linear Image Registration Tool (FLIRT) toolboxes. The manual and automatic labels were compared using Dice similarity coefficients (DSCs). The DSC values were compared using Friedman's test for repeated measures. Results: Comparing cerebellum and thalamus masks against the manually segmented masks, the median DSC values for ANTs and FLIRT were 0.72 [interquartile range (IQR) = 0.6-0.8] and 0.54 (IQR = 0.4-0.6), respectively. A Friedman's test indicated that the ANTs registration methods, primarily nonlinear methods, performed better than FLIRT (p < 0.001). Conclusion: Deformable registration methods provided the most accurate results relative to manual segmentation. Overall, this semi-automatic subcortical segmentation method provides reliable performance to segment subcortical volumes in fetal MR images. This method reduces the costs of manual segmentation, facilitating the measurement of typical and atypical fetal brain development.

Companion Animals and Adolescent Stress and Adaptive Coping During the COVID-19 Pandemic.

The COVID-19 pandemic has resulted in significant social disruptions for youth caused by lockdowns, school closures, and a lack of in-person social interactions. Companion animals are prevalent in US households and may provide a source of emotional support and motivation for youth to engage in adaptive coping behaviors during social challenges. The goals of this study were to assess if dog owners, non-dog pet owners, and non-pet owners differed in stress levels, positive affect, and use of adaptive coping strategies such as increased time outdoors, regular walking, and healthy behaviors. This study used data collected during the COVID-19 pandemic from the Adolescent Brain Cognitive DevelopmentSM (ABCD) Study, a large, nationally representative dataset of American youth. In a cross-sectional sample of 6,069 adolescents, there were significant, but small, relationships between owning a non-dog pet and lower levels of positive affect, and both dog owners and non-dog pet owners reported higher perceived stress compared with non-pet owners. Dog ownership was associated with higher odds of using healthy coping strategies compared with non-pet owners, but this relationship was not significant when controlling for demographic variables. Dog owners reported higher odds of having a walking routine and spending time outdoors compared with non-pet owners. Overall, the results suggest no buffering effect of pet ownership on youth mental wellbeing, but dog ownership is associated with some healthy coping behaviors linked to walking.

Amygdala subnuclei volumes, functional connectivity, and social-emotional outcomes in children born very preterm.

Children born very preterm can demonstrate social-cognitive impairments, which may result from limbic system dysfunction. Altered development of the subnuclei of the amygdala, stress-sensitive regions involved in emotional processing, may be key predictors of social-skill development. In a prospective cohort study, 7-year-old children born very preterm underwent neurodevelopmental testing and brain MRI. The Child Behavioral Checklist was used to assess social-emotional outcomes. Subnuclei volumes were extracted automatically from structural scans (n = 69) and functional connectivity (n = 66) was examined. General Linear Models were employed to examine the relationships between amygdala subnuclei volumes and functional connectivity values and social-emotional outcomes. Sex was a significant predictor of all social-emotional outcomes (P < 0.05), with boys having poorer social-emotional outcomes. Smaller right basal nuclei volumes (B = -0.043, P = 0.014), smaller right cortical volumes (B = -0.242, P = 0.02) and larger right central nuclei volumes (B = 0.85, P = 0.049) were associated with increased social problems. Decreased connectivity strength between thalamic and amygdala networks and smaller right basal volumes were significant predictors of greater social problems (both, P < 0.05), effects which were stronger in girls (P = 0.025). Dysregulated maturation of the amygdala subnuclei, along with altered connectivity strength in stress-sensitive regions, may reflect stress-induced dysfunction and can be predictive of social-emotional outcomes.

Evaluating the impact of community interventions on childhood obesity in populations living in low-income households in Los Angeles: A simulation study.

BACKGROUND: The complex multifactorial nature of childhood obesity makes community interventions difficult to evaluate using traditional approaches; innovative methods are needed. OBJECTIVE: To evaluate the impact of various interventions targeting childhood obesity-related behaviours, and classified as using a micro-level (e.g., home visitation programs) or macro-level (e.g., business practices) strategy, on obesity among children enrolled in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC). METHODS: We simulated a population of 1500 children enrolled in WIC, with specific diet, physical activity, breastfeeding behaviours and body mass index z-scores (BMIz), following them from age 2 to 5 years. RESULTS: Combined interventions targeting breastfeeding appeared to be moderately effective, reducing BMIz by 0.03 (95% CI -005, -0.01). Two strategy-specific interventions, home visitation programs and business practices targeting obesity-related behaviours, appeared to be moderately effective at reducing BMIz by 0.04 (95% CI -0.06, -0.02) and 0.02 (95% CI -0.04, 0.00), respectively. Contrary to expectation, combining all micro and macro interventions appeared to have no impact or moderately increased the proportion of obesity/overweight among children. CONCLUSION: Interventions targeting breastfeeding behaviour were most effective when both micro and macro strategies were implemented. Interventions targeting obesity-related behaviours in general were effective for two strategies, home visitation and business practices.

From Regulating Emotions to Less Lonely Screen Time: Parents' Qualitative Perspectives of the Benefits and Challenges of Adolescent Pet Companionship.

Adolescence is a prime developmental period to explore human-pet relationships, particularly given that teens are often relying less on their families, and more on other attachment figures such as peers and pets. However, most research on pet companionship is conducted with adults and young children. Moreover, lived experiences around having pets in households with adolescents are underexplored, particularly from parents' perspectives. This qualitative interview study of 31 parents/guardians in the Northeast U.S. explored perceptions of the benefits and challenges of having pets for their adolescent's well-being as well as how adolescents affected their pet's well-being. Our three main themes for perceived benefits of pets included social (e.g., reducing anxiety), physical (e.g., screen time companionship), and emotional (e.g., regulation of difficult emotions such as anger, loneliness). Challenges to adolescent well-being included such social topics as family tension around unevenly shared responsibilities, physical themes such as problematic animal behaviors, and emotional themes related to grieving the passing of pets. We offer a developmental systems approach to understanding pets within adolescent families, noting future directions for developing family interventions to improve pet-adolescent interactions given the demands of child and pet upbringing during adolescence.

Financial fragility and demographic factors predict pet owners' perceptions of access to veterinary care in the United States.

OBJECTIVE: Access to veterinary care is critical for pet, human, and community health. However, inequities in how easily pet owners can access veterinary care may exacerbate health disparities in vulnerable populations. This research analyzed pet owners' perceptions of access to veterinary care in order to understand how demographic characteristics and financial fragility predict perceived access to veterinary services. SAMPLE: This study utilized survey data (n = 750) from a larger cross-sectional survey of adults in the US conducted by the Tufts University Equity Research Group. PROCEDURES: Survey data were collected in May and June of 2020 from a nationally representative group of pet owners via an online panel. Descriptive statistics, ANOVAs, and a sequential linear regression model were conducted in order to predict perceived access to veterinary care. RESULTS: Results of a sequential linear regression model indicated that race or ethnicity, education, and financial fragility significantly predicted perceived ease of access to veterinary care (F[7,617] = 19.80; P < .001). Additionally, financial fragility was prevalent among most pet owners of almost all income brackets, highlighting the need for more research into the cost burden of veterinary care. CLINICAL RELEVANCE: Future studies should focus on diverse sampling strategies that capture the experiences of minority pet owners in order to further understand issues of access in veterinary medicine.

Restaurant dining during the COVID-19 pandemic among adults with low-income in the United States.

The COVID-19 pandemic caused widespread non-essential business closures in the U.S., which may have disproportionately impacted food consumption in lower-income communities, in part due to reduced access to healthy and affordable foods, as well as occupations that may have required working outside the home. The aims of this study were to examine restaurant dining behaviors (including drive-through, takeout, and delivery) at fast-food and non-fast-food (i.e., fast casual and full-service ['other']) restaurants and the impact on diet quality among racially/ethnically diverse low-income adults during the early months of the pandemic. Participants completed an online survey using CloudResearch regarding restaurant dining behaviors in the past week (during June 2020) and during a typical week prior to the pandemic. Diet quality was measured using the Prime Diet Quality Score (PDQS). Surveys from 1,756 low-income adults (incomes <250% of the Federal Poverty Level) were analyzed using chi-squared tests to examine differences in demographic characteristics among those dining at restaurants during the pandemic, as well as to examine differences in dining frequency compared with prior to COVID-19. Negative binomial regressions were used to examine the mean frequency of eating food from fast-food and other restaurants, adjusted for socio-demographic characteristics. This study found reductions in fast-food and other restaurant dining compared with prior to COVID-19, although overall restaurant consumption remained high with over half of participants reporting fast-food consumption in the week prior (average consumption of twice per week). Greater fast-food consumption was associated with poorer diet quality. In conclusion, while fast-food consumption was slightly lower during the pandemic, the overall high levels observed among socioeconomically disadvantaged adults remains concerning, highlighting the continued need for initiatives and policies to encourage greater access to and consumption of affordable and healthier foods.

Family Dog Ownership and Youth Physical Activity Levels: A Scoping Review.

ABSTRACT: Higher youth physical activity (PA) is associated with favorable health outcomes. The PA Guidelines for Americans recommend school-aged children complete at least 60 minutes of daily PA. Only one in three children meet these guidelines. Dog walking and play are potential strategies to increase youth PA. This scoping review summarizes the existing literature on familial dog ownership and youth PA levels and identifies gaps in the literature to inform future studies. Of nine studies that compared PA levels among youth with and without dogs, 77.8% reported a positive association between dog ownership and PA. The majority of studies investigating dog ownership and youth PA are cross-sectional and suggest dog ownership is associated with increased youth PA. Longitudinal studies are needed to determine whether the relationship is causal. Interventions to increase dog-facilitated PA in youth also are needed. Future studies should examine the dog ownership-PA relationship in low-income and minority youth.

Demographic and contextual factors as moderators of the relationship between pet ownership and health.

OBJECTIVE: Companion animals are an important feature of the family system, and human-animal interaction is increasingly being recognized as an important social determinant of health. However, there is a need for more nuanced assessment of not only who owns pets, but how pet ownership is related to various health outcomes, and which sociodemographic and contextual factors moderate these associations. DESIGN: Secondary analysis of cross-sectional data collected from an online, probability-based panel to generate a nationally representative sample of adults in the United States (n = 1267). Data were analyzed using hierarchical and logistic regression models. RESULTS: Results suggested that pet owners are systematically different from non-pet owners on a number of key demographic and contextual characteristics, and these differences vary somewhat when looking at dog owners and cat owners. When controlling for individual and family-level covariates, pet ownership was not associated with overall health status or Body Mass Index, but dog ownership was associated with higher levels of physical activity. Pet ownership was associated with higher odds of having an anxiety disorder with gender moderating this relationship, but this association was not present for dog or cat owners, suggesting this relationship is limited to other types of pets. Higher odds of depression were associated with pet ownership (for both dog and cat owners), with employment status significantly moderating the relationship between dog ownership status and depression. CONCLUSIONS: These findings suggest that pet ownership is a complex and context specific phenomenon. Future research should carefully consider and control for sociodemographic predictors and use measurement and analysis approaches sensitive to the variations in human-animal relationships to fully understand how pets contribute to individual and family health and well-being.

Assessing Service-Learning in Community-Based Veterinary Medicine as a Pedagogical Approach to Promoting Student Confidence in Addressing Access to Veterinary Care.

Community-based veterinary medicine is a growing field, and veterinary students need to be able to work with clients facing complex barriers to receiving veterinary care for their pet. Many veterinary clients experience challenges accessing veterinary care due to financial limitations, transportation access, language comprehension, the ability to comply to the care plan (e.g., disabilities, physical, or mental health challenges, substance use), the ability to come to the clinic during the hours that it is open, and the ability to communicate outside of the appointment. The goal of this study was to assess student confidence levels working in accessible care before and after participating in a service-learning-based community veterinary rotation. Results show significantly higher student confidence levels for every barrier after completing the Tufts at Tech (TAT) Clinical Rotation at Cummings Veterinary School of Medicine. Additionally, 86% (n = 85) of students strongly agreed or agreed that TAT affected their thoughts about community medicine, and 77% (n = 76) strongly agreed or agreed that the rotation affected their feelings about underserved clients. Service-learning rotations in community-based veterinary medicine could be one pedagogical approach in training veterinary students to work with a diverse clientele.

Children's Perception of Animacy: Social Attributions to Moving Figures.

Adults describe abstract shapes moving in a goal-directed manner using animate terms. This study tested which variables affect school-aged children's descriptions of moving geometrical shapes. Children aged 5 to 9 years were shown displays of interacting geometrical shapes and were asked to describe them. Across participants, instructions, number of moving figures, whether a figure caught another, and complexity of the scene were manipulated. Nine-year-olds used significantly more animate phrases than 5-year-olds. Furthermore, we found an Age by Condition interaction. Five-year-olds made significantly more animate statements in the animate condition, while 7-year-olds and 9-year-olds were less affected by instructions. Scene complexity increased children's use of animate phrases. Number of agents present on the screen and whether a catch occurred did not impact children's animate attributions. Our results support the hypothesis that children, like adults, are attuned to animacy cues and describe chasing agents in animate terms.
