Overweight and Obese Pet Owners: Respondent and Pet Characteristics in the Rural Midwestern United States

The obesity epidemic has impacted both people and pets in the rural Midwestern United States (MWUS). Tailoring health advice to the socio-demographic characteristics and dietary patterns of owners and their pets can help promote adherence to health behavior changes for owners and foster health improvements for both owners and pets. The authors completed this cross-sectional study in the rural MWUS with the objective of describing health-related characteristics of non-over-weight/obese versus overweight/obese [NOO vs. OO] cat and dog owners and their pets. The primary aim was to detect differences that could inform health recommendations. For both cat and dog owners, dietary and lifestyle profiles differed between those who were non-overweight/obese and those who were overweight/obese. NOO dog owners trended toward fewer health problems, took fewer medications (p < 0.02), took more supplements (p < 0.03), and ate less fast food (p < 0.03) and more fish (p < 0.001) than OO owners. Dogs owned by NOO owners had more owner-initiated activity (M ± SD: 44.6 ± 63.0 vs. 27.2 ± 26.4 min/d) and were on more supplements (p < 0.003). NOO cat owners were younger (p < 0.03), had fewer health problems (p < 0.04), took fewer medications (p < 0.04), engaged in more exercise (p < 0.02), and ate less fast food (p < 0.03) than OO cat owners. The only significant difference between cats of NOO vs. OO owners was their predominant gender: 57% vs. 74% female (p < 0.01). These findings have implications for marketing, education, and health care for both owners and pets. Further investigation of the relationship between pet ownership and health is warranted.     

The Protective Association between Pet Ownership and Depression among Street-involved Youth: A Cross-sectional Study

Street-involved youth represent a particularly vulnerable subsection of the homeless population and are at increased risk of health problems, substance abuse, and depression. Qualitative research has demon- strated that animal companions help homeless youth cope with loneliness, are motivators for positive change, such as decreasing drug or alcohol use, provide unconditional love without judgement, and improve youths’ sense of health. To quantitatively investigate the association between depression and pet ownership among street-involved youth, a cross-sectional study was per- formed with a convenience sample of 189 street-involved youths who were surveyed in four cities in Ontario, Canada, 89 of whom were pet owners and 100 of whom were not. Logistic regression modelling found pet ownership to be negatively associated with depression in the study population (controlling for gender, regular use of drugs, and time since youth left home), with the odds of being depressed three times greater for youths who did not own pets. While pet ownership among street-involved youth has many liabilities, includ- ing impairing youths’ ability to access shelter, services, and housing and employment opportunities, companion animals may offer both physical and psychosocial benefits that youth have difficult attaining. This finding highlights the importance of increased awareness among youth service providers of the potential impacts of pet ownership for street-involved youth.     

Pet Ownership,Other Domestic Relationships,and Satisfaction with Life among Seniors: Results from a Canadian National Survey

ABSTRACT

Given unprecedented aging in the global population along with the physical and psychological challenges associated with aging, it is important to identify ways to protect and promote quality of life for seniors. Previous research has suggested that pet ownership may confer a variety of health and social benefits among seniors. The purpose of this analysis was to determine whether pet ownership was associated with satisfaction with life among Canadian seniors. Quantitative data were obtained from the Canadian Community Health Survey—Healthy Aging, a nationally representative survey of Canadians ≥ 45 years of age conducted between December 2008 and November 2009. Analyses were restricted to a subsample of 11,973 individuals ≥ 65 years of age, and multiple logistic regression was used to model the relationship between pet ownership and satisfaction with life while controlling for sociodemographic factors. The final model was stratified to detect interaction. Pet ownership was negatively correlated with satisfaction with life in the sample as a whole (AOR = 0.79, 95% CI = 0.72–0.87) and among those who were married, in common-law relationships, and/or lived with others, while no association was found among those who were widowed, single, or living alone. Among those who were both divorced and living alone, pet ownership demonstrated the potential for being associated with greater satisfaction with life (AOR = 1.24, 95% CI = 0.89–1.73). Overall, this analysis showed that the relationship between seniors and their pets is complex. Whether pet ownership correlates with satisfaction with life appears to depend on the presence and nature of other domestic relationships.     

Beliefs Underlying Dog Owners' Health Care Behaviors: Results from a Large,Self-Selected,Internet Sample

ABSTRACT

Various behaviors must be performed by owners to promote good health for their dogs. The aim in this study was to use the results of an online survey, completed by 1,016 self-selected, Australian dog owners, to investigate relationships between demographic factors, beliefs, dog–owner relationship variables, and the performance of health-promoting behaviors. Specific behaviors examined included the provision of annual vaccinations and health checkups by a veterinarian, regular grooming and exercise, and the provision of a nutritionally balanced diet. Reported compliance was high in the self-selected sample, ranging between 77.8% for annual vaccinations and 98.8% for the provision of a nutritious diet. Regression analyses revealed that all of the behaviors we measured could be predicted from beliefs relating to health care practices and dog–owner relationship variables independently of demographic factors. The extent of dog and owner interactions, as well as the extent to which owners perceived important others to be supportive of the behaviors, emerged as particularly important variables. These statistically robust findings have implications for campaigns encouraging pet health promotion by owners.     

Examining Differences between Homebound Older Adult Pet Owners and Non-pet Owners in Depression,Systemic Inflammation,and Executive Function

Homebound older adults are prone to depression, which is linked to systemic inflammation that promotes executive function decline. A companion animal may reduce the negative biobehavioral processes asso- ciated with depression, inflammation, and reduced executive function in homebound older adults. The primary aim of this study was to examine dif- ferences between homebound older adult pet owners and non-pet owners in depression, salivary C-reactive protein (CRP), and executive function. The secondary aim was to determine if the level of attachment to pets was as- sociated with depression, salivary CRP, and executive function. The study was cross-sectional and investigated homebound older adult pet owners and non-pet owners (n = 88) using psychometrically reliable and valid instru- ments (Geriatric Depression Scale Short Form and CLOX 1). Salivary CRP was assessed with immunoassay. Level of attachment to pets was measured using a Likert scale (0–10). Mean age for the total sample was 75 years (SD = 9). Forty-eight (55%) participants owned pets (56% dogs, 25% cats, 4% other pets, 15% both cats and dogs). Pet owners reported a high level of attachment to pets (Median = 10). Pet owners had significantly higher ex- ecutive function than non-pet owners (t = –2.07; p = 0.04) but there were no significant differences in executive function between cat owners and dog owners (t = 1.53; p = 0.14). Pet owners and non-pet owners were similar in depression (t = –1.80, p = 0.08) and salivary CRP levels (t = 0.27, p = 0.79). Level of attachment to pets was significantly and positively correlated with executive function (r = 0.30; p = 0.04) but was not significantly correlated with depression (r = 0.04, p = 0.77) or salivary CRP (r = –0.04, p = 0.80). Compared with non-pet owners, pet owners had better executive function but similar depression and salivary CRP levels. Reasons for these findings are unclear. Significant positive correlation be- tween pet attachment and executive function suggests further investigation in this area. Future studies with larger samples and a longitudinal design are needed to investigate the biobehavioral changes over time in relation to pet ownership, level of attachment to pets, and executive func- tion in homebound older adults.     

Pets and Happiness: Examining the Association between Pet Ownership and Wellbeing

Are pets associated with happiness in their owners? Some research has demonstrated positive connections between pets and the physical health of their owners, and more recently, research has shown the beneficial effects of pets on the negative aspects of mental health as well. However, much less research has focused on the relation between pets and the positive aspects of mental health, such as happiness. In the current study, 263 American adults completed an online survey using Amazon Mechanical Turk. Results indicate that pet owners were more satisfied with their lives than non-owners, but did not differ on other wellbeing measures, personality measures, emotion regulation, or need satisfaction. Dog owners scored higher on all aspects of wellbeing compared with cat owners, and differed on a number of other measures, including the Big Five personality traits, emotion regulation strategies, and need satisfaction. The relationship between type of pet owned and wellbeing was mediated by the Big Five personality traits (extraversion, agreeableness, and neuroticism, specifically), emotion regulation strategy, and need satisfaction. In addition, self-identified “dog people,” relative to “cat people,” showed similar patterns to those of dog owners, but the effects were often smaller and non-significant. Although there may not be many differences between those who own pets and those who do not, clearly owning a dog is associated with beneficial outcomes. Implications and future directions are discussed.     

Empathic Differences in Adults as a Function of Childhood and Adult Pet Ownership and Pet Type

ABSTRACT

Prompted by interesting but ambiguous findings that empathic differences in children may relate to pet preference and ownership, we extended the issue to an adult population. We investigated empathic-type responses in adults who lived with cats and/or dogs in childhood (Child-Pet) and currently (Adult-Pet), using the Interpersonal Reactivity Index (IRI), the Empathy Quotient (EQ), and the Animal Attitude Scale (AAS). Multivariate analyses of covariance, with Sex as the covariate (MANCOVA), revealed differences on the AAS, the IRI-Personal Distress scale, and the EQ-Social Skills factor. For the Child-Pet data, the Dog-Only and the Both (dog and cat) groups, compared with those in the Neither (no dog or cat) group, scored lower on the IRI-Personal Distress scale and higher on the EQ-Social Skills factor. On the AAS, all three pet groups (Dog-Only, Cat-Only, and Both) had higher ratings than the Neither group. For Adult-Pet data, the analyses revealed the Dog-Only group was lower on Personal Distress than the Neither group, and higher on Social Skills than the Neither group and the Cat-Only group. On the AAS, the Neither group was lower than all three pet-owning groups, like the childhood data, but strikingly, adults with both dogs and cats were higher on the AAS. The findings support research linking companion animals with empathic development. They warrant the continued exploration of the nature of empathic development (i.e., nature vs. nurture) and contribute to the increasing research field exploring the value of companion animals.     

Sociodemographics of Pet Ownership among Adolescents in Great Britain: Findings from the HBSC Study in England,Scotland, and Wales

The aim of this study was to assess the prevalence of pet ownership among adolescents in Great Britain and identify any sociodemographic differences between pet owners and non-pet owners. A total of 14,328 11-to 15-year-old adolescents from England, Scotland, and Wales were included in the analysis. Results revealed 15-year-old adolescents were significantly more likely than 11-year-old adolescents to own dogs (OR = 1.146, p < 0.001) but less likely to own fish, reptiles, or amphibians (OR = 0.629, p < 0.001), and small mammals (OR = 0.630, p < 0.001). Thirteen-year-olds were significantly more likely than 11-year-olds to own dogs (OR = 1.240, p = 0.021) and birds (OR = 1.299, p = 0.010), but significantly less likely to own fish, reptiles, or amphibians (OR = 0.795, p < 0.001). No gender differences were found. White adolescents were more likely than non-white adolescents to own all pet types. Those living in single-parent families were significantly more likely than those living with two parents to own dogs (OR = 1.186, p = 0.013) and cats (OR = 1.319, p < 0.001). Furthermore, those who reported living in stepfamilies were also more likely to own cats (OR = 1.428, p < 0.001). Adolescents with siblings were more likely to own cats (OR = 1.391, p = 0.001), fish, reptiles, or amphibians (OR = 1.220, p = 0.037) than adolescents without siblings. Adolescents with employed parents (both or one) were significantly more likely than those with unemployed parents to own dogs (OR = 1.414, p = 0.002) and birds (OR = 1.523, p = 0.018). Adolescents from high-affluence families were less likely than adolescents from low-affluence families to own dogs (OR = 0.888, p = 0.037), small mammals (OR = 0.832, p = 0.005), and birds (OR = 0.801, p = 0.046). Furthermore, family affluence differences were found in different pet types. Differences in all pet types and siblings were also found in a proxy measure of attachment to pets. This study provides evidence that pet ownership is related to several sociodemographic factors. These are relevant to take into account when performing HAI studies on adolescents.     

Resettled and unsettled: Syrian refugees and the intersection of race and legal status in the United States

ABSTRACT

In this article, I examine how the intersection of legal status and racialization shapes immigrant’s sense of security; or of legal and interpersonal safety. I draw on an ethnography of Syrian refugees who hold a permanent legal status, and who entered the United States in 2015, as Donald Trump was launching his campaign, amplifying anti-Muslim and anti-refugee sentiment. Following refugee experiences from their arrival, through the issuance of the first executive order banning travel in January 2017, I show how this group, racialized as Muslim and Arab, was categorized as a threat to national security. I also capture the uneven way they came to recognize their racialization. While a permanent legal status is likely a necessary condition for feeling a sense of security in the United States, I argue that it is an insufficient one. I show that Syrian refugees’ racialization attenuated their sense of security despite their legal status.     

Social jetlag and depression status: Results obtained from the Netherlands Study of Depression and Anxiety

Social jetlag, the misalignment between the internal clock and the socially required timing of activities, is highly prevalent, especially in people with an evening chronotype and is hypothesized to be related to the link between the evening chronotype and major depressive disorder. Although social jetlag has been linked to depressive symptoms in non-clinical samples, it has never been studied in patients with major depressive disorder (MDD). This study is aimed to study social jetlag in patients with major depressive disorder and healthy controls, and to further examine the link between social jetlag and depressive symptomatology. Patients with a diagnosis of MDD (n = 1084) and healthy controls (n = 385), assessed in a clinical interview, were selected from the Netherlands Study of Depression and Anxiety. Social jetlag was derived from the Munich Chronotype Questionnaire, by calculating the absolute difference between the midsleep on free days and midsleep on work days. Depression severity was measured with the Inventory of Depressive Symptomatology. It was found that patients with MDD did not show more social jetlag compared to healthy controls, neither in a model without medication use (β = 0.06, 95% CI: ?0.03–0.15, p = 0.17) nor in a model where medication use is accounted for. There was no direct association between the amount of social jetlag and depressive symptoms, neither in the full sample, nor in the patient group or the healthy control group. This first study on social jetlag in a clinical sample showed no differences in social jetlag between patients with MDD and healthy controls.     

Association of tryptophan hydroxylase gene polymorphism with depression, anxiety and comorbid depression and anxiety in a population-based sample of postpartum Taiwanese women

Depression and anxiety disorders often coexist clinically and both are known to have a genetic basis, but the mode of inheritance is too complicated to be determined so far. Serotonin is the biogenic amine neurotransmitter most commonly associated with depression and anxiety. Since tryptophan hydroxylase (TPH1) is the rate-limiting enzyme in serotonin biosynthesis, its role in the pathophysiology of these psychiatric diseases has been intensively studied. In this study, we examined whether polymorphism of the TPH1 gene is related to the etiology of major depression, anxiety and comorbid depression and anxiety. Five single nucleoside polymorphisms of the TPH1 gene were studied in a population-based sample of postpartum Taiwanese women consisting of 120 subjects with depression or/and anxiety and 86 matched normal controls. A significant difference (P = 0.0107) in genotype frequency for the T27224C polymorphism was found between the comorbid and normal groups, and risk analysis showed that the C allele conferred a strong protective effect (odds ratio = 0.27; 95% confident interval = 0.11-0.7). Three-allele haplotypes involving T27224C polymorphism were constructed and haplotype associations between particular haplotype combinations and various diseases identified. However, the associations were weak and the overall haplotype frequency profiles in all groups were similar. The results suggest that depression, anxiety, and comorbid depression and anxiety disorders may have related etiologies. In addition, this study suggests that the TPH1 gene might play a role in the pathogenesis of these closely related disorders.     

Toxocara infection and diminished lung function in a nationally representative sample from the United States population

The relevance of parasitic infection for the increasing incidence of asthma is a topic of considerable debate. Large population-based studies examining the association between helminth infection and specific measures of lung function in humans are lacking. This report sought to examine this association by exploring the differences in forced expiratory volume in 1 s (FEV₁) among participants with and without infection with Toxocara spp. using data from the Third National Health and Nutrition Examination Survey, undertaken by the United States Department of Health and Human Services, during 1988-1994. The results showed a significant association between diminished lung function and previous infection with Toxocara spp. Those with antibody evidence of Toxocara infection displayed FEV₁ that was 105.3 mL less than those without previous infection. This relationship persisted while controlling for age, sex, education level, BMI, smoking status, ethnicity, immigration, rural residence and dog ownership (fully-adjusted difference = 73 mL). These findings suggest diminished lung function in the presence of Toxocara infection and illustrate the urgent need for longitudinal data to more clearly define the immunological relationship with helminth infection and its potential influence on lung function.     

Inbreeding depression and outbreeding depression in Digitalis purpurea: optimal outcrossing distance in a tetraploid

An optimal crossing distance exists within plant populations if inbreeding and outbreeding depression operate simultaneously. In a population of tetraploid Digitalis purpurea, maternal plants were pollinated with donors at four distances: 0 (self-pollination), 1, 6 and 30 m. Lifetime fitness of F1 progeny was investigated in greenhouse experiments, and significant inbreeding and outbreeding depression were detected at five vs. three life history traits. Inbreeding depression increased at later life stages, whereas outbreeding depression was relatively constant. The existence of within-population outbreeding depression suggests substantial genetic structuring at moderate distances in D. purpurea, and corroborates recent findings of significant outbreeding depression in F1 progeny in polyploids. The moderate inbreeding depression found in this predominately outcrossing population supports the notion that effects of inbreeding are less severe in polyploids than in diploids.     

The pattern of physical comorbidity and the psychosocial determinants of depression: a prospective cohort study on a representative sample of family practice attendees in Slovenia

Objectives This study aims to present the patterns of physical comorbidity in depressed patients and factors strongly associated with depression in a representative sample of Slovenian family practice attendees.Methods Medical data was obtained for 911 general practice attendees. Of them, 221 (24.3%) were diagnosed as depressed. The depressive states of the subjects were evaluated using the Composite International Diagnostic Interview (CIDI). Physical comorbidity was assessed with a questionnaire covering the most common health problems in the Slovenian adult population. Several psycho-social factors were also analysed.Results Those variables significantly related to ICD depression were included in multivariate binary logistic regression analysis, adjusted by age, gender and education. The calculation included the chi-square, odds ratio (OR) with confidence interval (95% CI) and P-value. A P-value < 0.05 was marked as statistically significant.Conclusions There was no significant difference in the number of concurrent chronic diseases in depressed and non-depressed subjects. The risk of depression was increased by the presence of several concomitant factors. The burden of somatic co-morbidity was shown to be smaller than the impact of psychosocial determinants, which also acted as protective factors: the feeling of safety at home and the absence of problems in intimate relationships. The abuse of alcohol and drugs by a family member and current poor financial situation were strongly associated with depression. The impact of concurrent incontinence and chronic bowel disease was also important, though somewhat weaker.     

Increased risk of COVID‐19 infection and mortality in people with mental disorders: analysis from electronic health records in the United States

Concerns have been expressed that persons with a pre‐existing mental disorder may represent a population at increased risk for COVID‐19 infec­tion and with a higher likelihood of adverse outcomes of the infection, but there is no systematic research evidence in this respect. This study assessed the impact of a recent (within past year) diagnosis of a mental disorder – including attention‐deficit/hyperactivity disorder (ADHD), bipolar disorder, depression and schizophrenia – on the risk for COVID‐19 infection and related mortality and hospitalization rates. We analyzed a nation‐wide database of electronic health records of 61 million adult patients from 360 hospitals and 317,000 providers, across 50 states in the US, up to July 29, 2020. Patients with a recent diagnosis of a mental disorder had a significantly increased risk for COVID‐19 infection, an effect strongest for depression (adjusted odds ratio, AOR=7.64, 95% CI: 7.45‐7.83, p<0.001) and schizophrenia (AOR=7.34, 95% CI: 6.65‐8.10, p<0.001). Among patients with a recent diagnosis of a mental disorder, African Americans had higher odds of COVID‐19 infection than Caucasians, with the strongest ethnic disparity for depression (AOR=3.78, 95% CI: 3.58‐3.98, p<0.001). Women with mental disorders had higher odds of COVID‐19 infection than males, with the strongest gender disparity for ADHD (AOR=2.03, 95% CI: 1.73‐2.39, p<0.001). Patients with both a recent diagnosis of a mental disorder and COVID‐19 infection had a death rate of 8.5% (vs. 4.7% among COVID‐19 patients with no mental disorder, p<0.001) and a hospitalization rate of 27.4% (vs. 18.6% among COVID‐19 patients with no mental disorder, p<0.001). These findings identify individuals with a recent diagnosis of a mental disorder as being at increased risk for COVID‐19 infection, which is further exacerbated among African Americans and women, and as having a higher frequency of some adverse outcomes of the infection. This evidence highlights the need to identify and address modifiable vulnerability factors for COVID‐19 infection and to prevent delays in health care provision in this population.     

Unemployment and sleep: evidence from the United States and Europe

Using data for over 2.5 million individuals in the United States over the period 2006–2019 from the Behavioral Risk Factor Surveillance System (BRFSS) survey series we show the unemployed suffer sleep disruption. The unemployed suffer more short and long sleep than the employed and are more likely to suffer from disturbed sleep. These are especially problematic for the long-term unemployed and for the jobless who say they are unable to work. Similar findings on unemployment and poor sleep quality are found in European data. Increases in the unemployment rate raise the incidence of short sleep and lower sleep durations.     

Chronotype,depression and hippocampal volume: cross-sectional associations from the UK Biobank

Diurnal preference for evening time has been associated with increased odds for current depression and a number of indices of the disorder. In the current study, the association between chronotype and depression was explored in a population-based sample of 5360 adults aged between 40 and 70 years. Previous work has also suggested that larger hippocampal volume may be protective against depression. In an additional, exploratory analysis, hippocampal volume was compared in never-depressed early and late chronotypes (N= 3004). Definite eveningness was significantly associated with increased odds for probable lifetime depression after controlling for a number of confounding factors including neuroticism. Hippocampal volume did not differ between never-depressed early and late chronotypes. The current results extend previous work and add further weight to the argument that late chronotype represents a risk factor for depression.     

Post-partum depression: a comprehensive approach to evaluation and treatment

Post-partum depression (PPD) presents a significant disruption to the mother-infant relationship. Such disruptions are associated with risks to the neurological, socio-emotional and cognitive functioning of the developing infant. A review of this literature supports the early detection of PPD and the application of comprehensive, psychotherapeutic interventions that target the functioning of the infant, the mother and the mother-infant relationship. Ecological factors important to evaluation and avenues of intervention are emphasised. The need for further research to determine evidence-based methods of intervention is described.     

Plasma levels of nesfatin-1 as a new biomarker in depression in Asians: evidence from meta-analysis

Abstract

Objective: This study aims to review the alteration of plasma nesfatin-1 levels in patients with depression.

Methods: Under the guidance of the latest PRISMA checklist, a systematic review and meta-analysis were conducted by searching English database (PubMed, Web of Science, EMDASE) and Chinese database for relevant studies up to August, 2019. Pooled standardised mean difference (SMD) with 95% confidence intervals (CI) was calculated with the random effects model.

Results: Nine studies that reported the association between plasma levels of nesfatin-1 and the risk of depression with 567 patients and 447 control participants were included in the meta-analysis. Compared with the healthy controls, depressive patients had a higher plasma level of nesfatin-1 [SMD (95% CI):1.58(0.75, 2.41), Z?=?3.74, p for Z?<?0.001; I² = 96.8%, p for I² < 0.001]. The subgroup analyses and meta-regression failed to find the source of the heterogeneity. No evidence of publication bias was found either in Begg’s test (p?=?0.348) or the Egger’s test (p?=?0.523).

Conclusion: The present meta-analysis indicated that a higher plasma level of nesfatin-1 was associated with an increased risk of depression.
