Dog ownership, dog walking, and children's and parents' physical activity

Australian children's physical activity and screen time while in grandparental care

OBJECTIVE

The objective of this study was to explore Australian children's engagement in physical activity and screen time while being cared for by their grandparents.

METHOD

Grandparents (N = 1,190) providing ≥3 hours of weekly care to a grandchild aged 3-14 years completed an online survey assessing their grandchildren's movement behaviours while in their care. Descriptive statistics were computed for frequency of engagement in unstructured and structured physical activities, minutes spent playing outdoors, and minutes spent engaged in screen time. Regression analyses were conducted to assess socio-demographic predictors of movement behaviours.

RESULTS

Playing in the yard was the most common form of physical activity in which grandchildren reportedly participated (77% 'usually' or 'always'), followed by playing with toys/equipment (62%). Few (14-36%) frequently engaged in active transport. Children spent an average of 181 minutes per week engaged in screen-based activities.

CONCLUSIONS

There is an opportunity to improve children's movement behaviours while in grandparental care. Communicating to grandparents their importance in supporting an active lifestyle is warranted.

IMPLICATIONS FOR PUBLIC HEALTH

Findings highlight the importance of creating environments that facilitate play-based, outdoor activities. Ensuring children have access to play equipment while in the care of grandparents and improving access to and quality of neighbourhood parks may assist with activity promotion.

Longitudinal effects of dog ownership, dog acquisition, and dog loss on children's movement behaviours: findings from the PLAYCE cohort study

INTRODUCTION

Regular physical activity is important for children's physical and mental health, yet many children do not achieve recommended amounts of physical activity. Dog ownership has been associated with increased physical activity in children, however, there have been no longitudinal studies examining this relationship. This study used data from the Play Spaces and Environments for Children's Physical Activity (PLAYCE) cohort study to examine the longitudinal effects of dog ownership status on children's movement behaviours.

METHODS

Change in dog ownership from preschool (wave 1, age 2-5) to fulltime school (wave 2, age 5-7) was used as a natural experiment with four distinct dog ownership groups: continuing non-dog owners (n = 307), continuing dog owners (n = 204), dog acquired (n = 58), and dog loss (n = 31; total n = 600). Daily movement behaviours, including physical activity, sedentary time, sleep, and screen time, were measured using accelerometry and parent-report surveys. Differences between groups over time and by sex were tested using linear mixed effects regression models.

RESULTS

Girls who acquired a dog increased their light intensity activities and games by 52.0 min/day (95%CI 7.9, 96.0) and girls who lost a dog decreased their light intensity activities and games by 62.1 min/day (95%CI -119.3, -4.9) compared to no change among non-dog owners. Girls and boys who acquired a dog increased their unstructured physical activity by 6.8 (95%CI 3.2, 10.3) and 7.1 (95%CI 3.9, 10.3) occasions/week, compared to no changes among non-dog owners. Girls and boys who lost a dog reduced their unstructured physical activity by 10.2 (95%CI -15.0, -5.3) and 7.7 (95%CI -12.0, -3.5) occasions/week. Girls who lost a dog decreased their total physical activity by 46.3 min/day (95%CI -107.5, 14.8) compared to no change among non-dog owners. Continuing dog ownership was typically not associated with movement behaviours. Dog ownership group was not associated with changes in sleep and had mixed associations with screen time.

CONCLUSION

The positive influence of dog ownership on children's physical activity begins in early childhood and differs by child sex. Further research should examine the specific contributions dog-facilitated physical activity makes to children's overall physical activity, including the intensity and duration of dog walking and play.

Changes in walking practice and associated factors during the coronavirus disease 2019 pandemic

The coronavirus disease 2019 (COVID-19) pandemic has induced many lifestyle changes, with reductions in healthy activities, including walking. The aim of this cross-sectional study was to identify strategies to maintain good health during a pandemic. Demographics, walking habits, health behaviors, health status, recognition of social capital, and changes in walking practice of 800 residents were evaluated using a structured questionnaire. Among the participants, 73.9%, 15.8%, and 10.4% reported no change, a decrease, and an increase in walking practice, respectively. Individuals in their 50 s and 60 s showed 6.388- and 5.054-times greater increases in walking, respectively, than did those aged 19-29 years. Walking increased more among high-income people than among low-income people. Additionally, walking practice increased in people participating in social gatherings, those with pets that needed walks, those with a COVID-19 history, those who considered walking as both a habitual and leisure activity, those with nearly no stress, and those satisfied with their safety, the natural environment, and public transportation; other health behaviors or conditions were not related to an increase in walking practice. To maintain good health during a pandemic, walking practice should be promoted in people in their 20 s and low-income groups. Moreover, people should be encouraged to attend meetings, including online interaction, and safe walking routes should be created within the community. Walking should be encouraged as a method of relieving stress, and the benefits of walking for recovery after an infectious disease should be emphasized. Furthermore, the direct effects of walking should be studied.

Are children and dogs best friends? A scoping review to explore the positive and negative effects of child-dog interactions

Personal wellbeing is greatly influenced by our childhood and adolescence, and the relationships formed during those phases of our development. The human-dog bond represents a significant relationship that started thousands of years ago. There is a higher prevalence of dog ownership around the world, especially in households including children. This has resulted in a growing number of researchers studying our interactions with dogs and an expanding evidence base from the exploration of child-dog interactions. We review the potential effects of child-dog interactions on the physical, mental, and social wellbeing of both species. A search of the SCOPUS database identified documents published between January 1980 and April 2022. Filtering for key inclusion criteria, duplicate removals, and inspecting the references of these documents for additional sources, we reviewed a total of 393 documents, 88% of which were scientific articles. We were able to define the numerous ways in which children and dogs interact, be it neutral (e.g., sharing a common area), positive (e.g., petting), or negative (e.g., biting). Then, we found evidence for an association between childhood interaction with dogs and an array of benefits such as increased physical activities, a reduction of stress, and the development of empathy. Nonetheless, several detrimental outcomes have also been identified for both humans and dogs. Children are the most at-risk population regarding dog bites and dog-borne zoonoses, which may lead to injuries/illness, a subsequent fear of dogs, or even death. Moreover, pet bereavement is generally inevitable when living with a canine companion and should not be trivialized. With a canine focus, children sometimes take part in caretaking behaviors toward them, such as feeding or going for walks. These represent opportunities for dogs to relieve themselves outside, but also to exercise and socialize. By contrast, a lack of physical activity can lead to the onset of obesity in both dogs and children. Dogs may present greater levels of stress when in the presence of children. Finally, the welfare of assistance, therapy, and free-roaming dogs who may interact with children remains underexplored. Overall, it appears that the benefits of child-dog interactions outweigh the risks for children but not for dogs; determination of the effects on both species, positive as well as negative, still requires further development. We call for longitudinal studies and cross-cultural research in the future to better understand the impact of child-dog interactions. Our review is important for people in and outside of the scientific community, to pediatricians, veterinarians, and current or future dog owners seeking to extend their knowledge, and to inform future research of scientists studying dogs and human-animal interactions.

Benefits and Conflicts: A Systematic Review of Dog Park Design and Management Strategies

Simple Summary

Dog parks contribute physical and social benefits for both canines and their owners, especially during and since the COVID-19 pandemic. However, dogs in public places can create various conflicts. Growing numbers of scholars have explored strategies for effective park design and management. This systematic study synthesizes and analyze the benefits, conflicts, and strategies for the design and management of dog parks according to the PRISMA guidelines. Based on the summary of conflicts between canines, humans, and their environment, we present design and management guidance for dog parks to effectively mitigate these conflicts while enhancing the benefits of off-leash areas. While this study promotes a sustainable and healthy coexistence of canines and residents of built environments through appropriate design and management strategies, several research and practice gaps have been identified from the results, such as the dearth of experimental evidence and limitations of the physical benefits of dog parks. These research gaps provide opportunities for experts to address in future.

Abstract

Dog ownership and dog walking brings various health benefits for urban dwellers, especially since the COVID-19 pandemic, but trigger a number of controversies. Dog parks have become increasingly significant public resources in the pandemic to support these benefits while facing intense conflicts. To develop effective dog parks in urban settings, growing numbers of scholars have provided insights into the design and management strategies for addressing the benefits and conflicts. The objective of this study is to synthesize and analyze various aspects of dog park design and management and to assess identified strategies for enhancing their benefits while mitigating their drawbacks. Following the PRISMA guidelines, a systematic study was conducted to synthesize the benefits, conflicts, and management strategies of dog parks, supported by Citespace. Benefits and conflicts in dog park design and management have been synthesized and organized according to their frequency of presence and the statistical results. We analyzed and assessed existing design and management strategies. Through this systematic study, we discovered the need obtain o po experimental evidence on effective dog park design and management to enhance their benefits while mitigating their sources of conflict and limitations in the intensity of park visitors’ physical activity in off-leash areas. Guidelines for the design and management strategies for effective dog parks were made to enhance their benefits while alleviating conflicts in the future development of sustainable dog parks that promote healthy relationships between canines and residents in urban built environments.

Is Dog Owner Obesity a Risk Factor for Canine Obesity? A "One-Health" Study on Human-Animal Interaction in a Region with a High Prevalence of Obesity

Obesity in humans is a growing global problem and is one of the greatest public health challenges we face today. Most researchers agree that, as in humans, the incidence in the companion animal population is also increasing. The aim of this study was to evaluate the risk factors contributing to canine obesity in a region with a high rate of human obesity (Canary Islands, Spain), co-occurrence of obesogenic risk factors, and a canine population with a high percentage of unneutered dogs. We have focused on owner risk factors that promote obesity in humans, such as weight, lifestyle, nutritional habits, and low physical activity, among others. Thus, the human-animal interaction relationship that contributes to human obesity and influences canine obesity has been studied. A multicentre cross-sectional analytical study of 198 pairs of dogs from urban households and their owners was used. A multivariable logistic regression study was completed to analyse owner characteristics variables associated with canine obesity. This transdisciplinary study was conducted with physicians and veterinarians using a "One Health" approach. Our results suggest that, in a region of high obesogenic risk, obese/overweight dogs are primarily female, older than 6 years, and neutered. Being an overweight dog owner was found to be the most important factor in the occurrence of obesity in dogs. Owners of overweight dogs were mainly females, older than 40 years, who did not engage in any physical activity. A strong correlation has been found between dog owners with low levels of education and obesity in their dogs. We suggest that veterinarians should develop and design strategies to encourage pet owners to engage in physical activity with their dogs for the benefit of both.

A mobile health intervention to encourage physical activity in children: a randomised controlled trial

BACKGROUND

Despite immense benefits of physical activity on health and developmental outcomes, few children achieve recommended daily levels of physical activity. Given more than half of families with children own a dog, we investigated the effect of a mobile health (mHealth) intervention to encourage dog-facilitated physical activity through increased family dog walking and children's active play with their dog.

METHODS

The PLAYCE PAWS study was a three-armed randomised pilot trial conducted in Perth, Western Australia. Children aged 5-10 years with a family dog were randomised to 4 weeks of either 1) SMS-only intervention, 2) 'SMS + pedometer' intervention or 3) 'usual care' control. The mHealth intervention involved SMS messages to parents; the 'SMS + pedometer' group also received a dog pedometer and personalised dog steps diary. Parent-reported measures were collected at baseline, 1- and 3-months post intervention. The primary outcome was weekly frequency of family dog walking and dog play; secondary outcomes were child attachment to the dog and feasibility of the intervention.

RESULTS

A total of 150 children were randomised in staggered blocks to SMS-only (n = 50), 'SMS + pedometer' (n = 50) or usual care (n = 50). No differences were observed in family dog walking and dog play at 1-month. SMS-only children (OR 2.6, 95% CI 1.17, 5.83, P = 0.019) and all intervention children (OR 1.97, 95% CI 1.01, 3.86, P = 0.048) were more likely to increase total dog-facilitated physical activity (sum of family dog walking and dog play responses) at 3-months. The positive associations with total dog-facilitated physical activity disappeared (all P > 0.05) after adjusting for socio-demographic factors.

CONCLUSIONS

The PLAYCE PAWS mHealth intervention did not significantly affect dog-facilitated physical activity in children. Given high levels of dog ownership in the community, SMS prompts could be a low-cost intervention to encourage more physical activity in children. Further research is needed to understand how increased interaction with the family dog impacts on children's overall physical activity and other health and development outcomes.

Social-Ecological Correlates of Children’s Independent Mobility: A Systematic Review

Children’s independent mobility (IM) is associated with a range of benefits and understanding the factors that influence IM can support creation of effective interventions. The review (Prospero CRD42016042174) systematically summarized the available literature for social-ecological correlates of children’s IM in school-aged children and youth (aged 5–17 years). In this case, 53 studies were included and evaluated six individual, 15 interpersonal, 12 social environment, and 19 built environment- level variables. Most studies originated from Australia (n = 15) and Canada (n = 8) with most published in 2011 or later (n = 48). Variables that were consistently (positively and/or negatively) associated with children’s IM were age, ethnicity/race, child’s perceived competence, ownership of a house/access to house keys, having siblings, parents’ attitude toward IM and perception of child’s confidence, children’s interest in environment and activities, parents’ concern around traffic, housing/residential density, length of residency in one’s home, distance to destinations, and proximity to green space. Given the inter-related social-ecological correlates identified, intervention to promote children’s IM will likely need a multi-level and multi-sectoral approach. However, focus areas of building children’s skills and confidence, helping parents gain confidence in their children’s abilities, assuaging parental traffic concerns, and building environments with shorter distances to destinations of interest for children should be prioritized.

Parents' and Children's (6-12 Years Old) Physical Activity Association: A Systematic Review from 2001 to 2020

Worldwide, studies reveal that a significant proportion of adults and children do not meet the recommended guidelines for physical activity (PA). Therefore, it is crucial that proxy determinants for child physical activity enhancement could be identified. Parents have been considered to have a key role in child adherence to physical activity. Thus, this systematic review aimed to identify association between parents’ and children’s PA. The search of scientific papers was conducted from 31 October 2020 until 31 January 2021, on the Web of Science, Scopus, Psycinfo, SportDiscus, and Pubmed databases. The PRISMA protocol was used. Findings indicate a consistent association between parents’ and children’s (6–12 years old) PA. Despite the imbalance of the number of assessed fathers and mothers with the latter clearly overrepresented, a trend towards the same gender dyads on PA significant and positive association (father/son, mother/daughter) was evidenced. Results support the relevant importance of parents’ PA as role modeling (either explicitly or implicitly) for children’s PA. Besides, results revealed the importance of promoting PA in family for the enhancement of children’s PA. Moreover, and given the positive impact of exerting PA with the children on children’s PA, parents should spend more time practicing PA with their children, especially on MVPA and meeting the recommended guidelines for PA. Future studies should highlight the role of mediator variables on this interaction process, extending the knowledge on the contribution of other factors to the requested enhancement of children adherence to PA practice.

Barriers and motivators for preschoolers playing and walking with their dog: Results from qualitative research

ISSUES ADDRESSED

A large proportion of preschoolers do not meet the recommended three hours of daily physical activity. A potential source of daily physical activity could be that provided via the family dog. This qualitative study aimed to explore the barriers and motivators to preschoolers playing with their dog and participating in family dog walks.

METHODS

Twelve in-depth interviews were conducted with parents of preschoolers who owned a dog. A semistructured interview guide was used, and transcripts were analysed thematically.

RESULTS

Factors influencing preschoolers playing with their dog and participating in family dog walks included parents' level of attachment to their dog, parental history of dog ownership, parent modelling of safe dog play, type of play the family dog enjoys and proximity to dog- and child-friendly destinations. Other factors such as the size, level of socialisation and perceived exercise requirements of the dog, physical environment factors such as backyard size and individual factors such as time and existing commitments were also reported.

CONCLUSIONS

A number of dog, individual and physical environment specific factors should be considered when promoting preschooler physical activity through dog walking and play. SO WHAT?: A large proportion of preschoolers do not meet the recommended three hours of daily physical activity. In Australia, 43% of Australian households with children aged four to five own a dog. Dog-facilitated physical activity through family dog walks and active play could be an effective strategy for increasing preschooler physical activity.

The relationship between dog ownership, dog play, family dog walking, and pre-schooler social-emotional development: findings from the PLAYCE observational study

BACKGROUND

Regular physical activity provides children with health and developmental benefits. This study investigated if active play and walking with the family dog was associated with better social-emotional development in young children.

METHODS

We surveyed 1646 parents to ascertain if families with pre-schoolers owned a dog, and the frequency per week their child went on family dog walks or actively played with their dog. The parent-report version of the Strengths and Difficulties Questionnaire (SDQ) was used to measure children's social-emotional development.

RESULTS

Children from dog-owning households had reduced likelihood of conduct problems (odds ratio (OR) = 0.70; 95% confidence interval (CI): 0.54, 0.90), peer problems (OR = 0.60; 95% CI: 0.46, 0.79), and total difficulties (OR = 0.77; 95% CI: 0.59, 0.99) and increased likelihood of prosocial behavior (OR = 1.34; 95% CI: 1.06, 1.68) compared with children without a dog. Within dog-owning households, family dog walking at least once/week (OR = 1.45; 95% CI: 1.02, 2.08) and active play with the family dog three or more times/week (OR = 1.74; 95% CI: 1.16, 2.59) increased the likelihood of prosocial behaviors. Family dog walking at least once/week also reduced the likelihood of total difficulties (OR = 0.64; 95% CI: 0.42, 0.96).

CONCLUSIONS

Our findings highlight the possible physical activity and social-emotional developmental benefits of family dog ownership for pre-schoolers, and that these benefits may present in early childhood.

IMPACT

Young children from dog-owning families had lower peer problems and conduct problems, and higher prosocial behaviors than children from non-dog-owning families. Children of dog-owning families who walked or played with their dog more often also had better prosocial behaviors. Positive social-emotional development was associated with dog ownership, family dog walking, and dog play in young children. Highlights that the social-emotional benefits of owning a dog may begin early in childhood. Due to the high level of pet ownership in households with children, these findings suggest having a dog and interacting with it through play and walking may be important mechanisms for facilitating young children's social-emotional development.

A study protocol for a randomised controlled trial to evaluate the effectiveness of a dog-facilitated physical activity minimal intervention on young children's physical activity, health and development: the PLAYCE PAWS trial

BACKGROUND

Pet ownership brings many health benefits to individuals. In children developmental benefits can extend to improved self-esteem, better social competence and decreased loneliness. The majority of households with children own a dog, however only a small proportion of children gain the benefits of dog ownership through dog walking and play. There are few intervention studies investigating the impact of dog-facilitated physical activity in children. The PLAYCE PAWS study aims to test a minimal-contact intervention through the use of mobile health ("mhealth") strategies, i.e. text (SMS) messages, to parents to encourage their children to walk and play with their dog more, and evaluate the impact on children's overall physical activity and development.

METHODS/DESIGN

The PLAYCE PAWS intervention study will target parents in dog-owning families with children aged 5 to 8 years in Perth, Western Australia. Approximately 150 dog-owning parents and children will be randomly allocated into either one of two intervention groups or a 'usual care' control group. The first intervention group will receive SMS messages over 4 weeks to encourage and prompt parents to undertake dog walking and dog play with their child. The second intervention group will receive the same text messages, plus a dog pedometer and personalised 'dog steps' diary for their child to complete. Parent-reported outcome measures include changes in children's dog walking and play, overall physical activity, socio-emotional development, self-regulation, self-esteem, empathy, and level of attachment to their dog.

DISCUSSION

The PLAYCE PAWS study appears to be the first to examine the effectiveness of a low-cost, mhealth intervention for increasing young children's physical activity through dog walking and play. Given the high prevalence of dogs as family pets, this study presents a valuable opportunity to investigate if mHealth interventions encourage children to walk and play with their dog more, and if there are any associated impact on children's overall physical activity and socio-emotional well-being. If effective, a larger trial or program could be implemented at low-cost and with wide reach in the community.

Dog ownership and adults' objectively-assessed sedentary behaviour and physical activity

Evidence suggests a positive effect of dog ownership on physical activity. However, most previous studies used self-reported physical activity measures. Additionally, it is unknown whether owning a dog is associated with adults’ sedentary behaviour, an emerging health risk factor. In this study, physical activity and sedentary behaviour were objectively collected between 2013 and 2015 from 693 residents (aged 40–64 years) living in Japan using accelerometer devices. Multivariable linear regression models were used, adjusted for several covariates. The means of total sedentary time and the number of long (≥ 30 min) sedentary bouts were 26.29 min/day (95% CI − 47.85, − 4.72) and 0.41 times/day (95% CI − 0.72, − 0.10) lower for those who owned a dog compared to those not owning a dog, respectively. Compared with non-owners, dog-owners had significantly higher means of the number of sedentary breaks (95% CI 0.14, 1.22), and light-intensity physical activity (95% CI 1.31, 37.51). No significant differences in duration of long (≥ 30 min) sedentary bouts, moderate, vigorous, and moderate-to-vigorous-intensity physical activity were observed between dog-owners and non-owners. A novel finding of this study is that owning a dog was associated with several types of adults’ sedentary behaviours but not medium-to-high-intensity physical activities. These findings provide new insights for dog-based behavioural health interventions on the benefits of dog ownership for reducing sedentary behaviour.

The Concerns, Difficulties, and Stressors of Caring for Pets during COVID-19: Results from a Large Survey of U.S. Pet Owners

Pets may be a positive presence for their owners during the Coronavirus Disease 2019 (COVID-19) pandemic. However, it is pertinent to identify the hardships associated with pet ownership. We conducted a large-scale survey of U.S. pet owners (n = 2254) in spring and summer 2020 to assess the ways that relationships with pets impacted life during COVID-19. We used thematic analysis to analyze 3671 open-ended responses to three prompts. Reported concerns fell into three major categories: (1) pet-focused (meeting needs of pets; procuring supplies; accessing veterinary care; new and emerging behavioral issues; fate of the pet if owner becomes ill; general safety and well-being), (2) human-focused (issues with working from home; well-being and mental health; balancing responsibilities), and (3) household-focused (disease spread; economic issues). Quantitative analyses showed that the owner's strength of attachment to their pet, economic resources, and relationship status were associated with the types of concerns expressed. Results from this study indicate that pet owners experienced unique hardships related to changes in everyday life from the COVID-19 pandemic. These hardships should be considered alongside the potential benefits found in other studies in order to manage pet owner expectations, prevent pet relinquishment, and more fully understand multifaceted human-companion animal relationships.

Dog Walkers’ Views of Urban Biodiversity across Five European Cities

Contact with nature makes people feel better, live healthier and act more environmentally-friendly. We hypothesized that dog walking, an omnipresent people–nature interaction in cities, translates to a more positive view of urban nature and, subsequently, to more support for conservation initiatives. Insights into such positive side-effects of dog walking are relevant for dog-related urban policies that often focus on negative impacts of dogs (e.g., health risks, disturbance of wildlife). Based on a field survey in five European cities (N = 3717), we analyzed if people who walked dogs regularly valued four urban ecosystem types (park meadows, wastelands, streetscapes, forests), and the plant species diversity within, differently from other people. Opposite to our hypothesis, participants from both groups valued urban ecosystems and their biodiversity very similarly across the cities. Thus, our study does not confirm that regular dog walkers value natural elements more than other people. It thus remains an important challenge for urban planners to balance services and disservices of dog walking in urban greenspaces.

Dog-walking in dense compact areas: The role of neighbourhood built environment

There is a dearth of evidence about how high-density living may influence dog-walking behaviour. We examined associations between neighbourhood built environment attributes and dog-ownership and dog-walking behaviour in Japan. Data from 1058 participants were used. The dog-ownership was 18.8%. All neighbourhood built attributes (excluding availability of parks) were negatively associated with dog-ownership. Among dog-owners, these same attributes were positively associated with any dog-walking in a usual week and with achieving 150-min per week of physical activity through dog-walking alone. These findings provided evidence on the importance of neighbourhood built environment attributes on dog-ownership and dog-walking behaviour in dense and compact areas. The urban design and public health implication of these findings is that the built environment attributes in high-density living areas may have different impacts on dog-ownership and dog-walking: while living in a walkable neighbourhood may not be conducive to dog-ownership, it may support dog-walking in such areas. Programs targeting dog-owners in high-density areas might be needed to encourage them to walk their dogs more. If successful, these programs could contribute to higher physical activity levels among dog-owners.

Improving medication adherence in the pediatric population using integrated care of companion animals

Medication non-adherence occurs in more than half of children with chronic conditions. Unfortunately, most strategies for improving adherence have had limited success in the pediatric population highlighting the need for novel interventions that establish healthy self-management habits for children and adolescents. In this paper we discuss innovative strategies to improve adherence by embedding a medical regimen within a pet care routine, thereby capitalizing on the benefits of a structured habit while providing opportunities for development of autonomy in children and fostering collaborative parent interactions.

Subjectively and Objectively Assessed Behavioral, Social, and Physical Environmental Correlates of Sedentary Behavior in Preschoolers

OBJECTIVE

To investigate associations between preschoolers' objective leisure-time sedentary behavior and a comprehensive set of subjective and objective potential correlates of sedentary behavior across the behavioral, social, and physical environmental domains on both the family and community level.

STUDY DESIGN

In 3- to 6-year-old preschoolers (n = 738) from 52 preschools in Southern Germany, leisure time spent in sedentary behavior was assessed by accelerometry in 2008-2009. Family- and community-level potential correlates of sedentary behavior from different domains (behavioral, social, and physical environmental) were subjectively (ie, by parent-proxy report) and objectively (ie, by routine administrative data) assessed.

RESULTS

None of the objective social and physical environmental correlates showed associations with sedentary behavior. Leisure-time sedentary behavior decreased with greater levels of moderate-to-vigorous physical activity (both weekends and weekday afternoons), participation in organized sports, parental leisure-time physical activity, as well as greater parental traffic safety perceptions (weekends only).

CONCLUSIONS

Targeting multiple health behaviors at the same time (ie, physical activity and sedentary behavior) and focusing on the entire family (ie, preschoolers, parents, and potentially older siblings) might be useful opportunities to reduce sedentary behaviors in preschoolers.

Expectations for dog ownership: Perceived physical, mental and psychosocial health consequences among prospective adopters

Dog ownership is popular worldwide, with most human-dog dyads forming successful attachment bonds. However, millions of dogs are surrendered to animal shelters annually, possibly due to mismatches between owner expectations and the realities of dog ownership. The aim of the current study was to explore the benefits and challenges people expect from dog ownership and how these expectations vary with previous ownership history. An Australian-wide sample of 3465 prospective adopters completed a self-administered online questionnaire about the physical, mental and psychosocial health benefits and challenges they associated with dog ownership. Among the potential benefits, respondents expected increased walking (89%), happiness (89%) and companionship (61%) and decreased stress (74%) and loneliness (61%). Among the challenges, they expected increased responsibility (64%) and dog training (62%). Ownership history influenced respondents’ expectations, with previous/current dog owners having consistently greater odds of expecting benefits and reduced odds of expecting challenges than non-owners. A possible explanation is that previous/current dog owners’ exhibit bias when considering dog ownership by selectively recalling positive experiences from previous ownership. Our findings support the need for education of prospective dog owners to ensure their expectations align with the reality of ownership, based on current scientific evidence.

The association between dog ownership or dog walking and fitness or weight status in childhood

BACKGROUND

Health benefits of dog walking are established in adults: dog owners are on average more physically active, and those walking their dogs regularly have lower weight status than those who do not. However, there has been little research on children.

OBJECTIVES

This study aimed to examine the association between dog ownership or dog walking and childhood fitness or weight status.

METHODS

A survey of pet ownership and involvement in dog walking was combined with fitness and weight status measurements of 1021 9 to 10-year-old children in the Liverpool SportsLinx study.

RESULTS

We found little evidence to support that children who live with, or walk with, dogs are any fitter or less likely to be obese than those who do not.

CONCLUSIONS

This is an important finding, as it suggests that the activity that children currently do with dogs is not sufficient enough to impact weight status or fitness.

The Influence of Family Dog Ownership and Parental Perceived Built Environment Measures on Children's Physical Activity within the Washington, DC Area

Sedentary behavior and physical inactivity are significant contributors to youth obesity in the United States. Neighborhood dog walking is an outlet for physical activity (PA). Therefore, understanding the relationship between built environment, dog ownership, and youth PA is essential. This study examined the influence of dog ownership and parental built environment perceptions on children’s PA in the Washington, D.C. area. In 2014, questionnaires were mailed to 2000 parents to assess family dog ownership; children’s outdoor dog walking or playing; and parental perceived built environment measures. Chi-square analyses examined differences in parental perceived built environment measures between children with and without family dogs. The sample included 144 children (50% female; average-age 9.7 years; 56.3% White; 23.7% African-American; 10.4% Asian-American; 29.9% owned dog). Only 13% and 5.6% of the children walked or played outdoors with the dog daily, respectively. A significantly greater proportion (p-value < 0.05) of parents who owned dogs recognized and observed some home built environment measures (e.g., traffic speed on most streets is 30 mph or less) that were PA -promoting for their children. Findings suggest that dog ownership may provide more positive parental perceptions of the neighborhood built environment, which supports children’s outdoor PA through dog walking and playing.

Subjectively and objectively assessed social and physical environmental correlates of preschoolers' accelerometer-based physical activity

BACKGROUND

Overweight and low levels of physical activity (PA) in preschoolers are major public health concerns. However, to date only few studies have investigated subjective and objective correlates of PA across different socioecological domains in preschoolers. We therefore simultaneously investigate associations between preschoolers' objectively measured leisure-time PA and a comprehensive set of subjective and objective potential PA correlates across the behavioral, social and physical environmental domains on both family- and community-level.

METHODS

In this cross-sectional study time spent in moderate-to-vigorous PA (MVPA) and total PA (TPA) were measured by combined accelerometry and heart rate monitoring in 735 3-6 year-old children from 52 preschools in Southern Germany. Family- and community-level potential correlates of PA from different domains (behavioral, social and physical environmental) were subjectively (i.e. by parent proxy-report) and objectively assessed. Their associations with PA on weekend days and weekday afternoons were tested by covariate-adjusted multilevel regression models.

RESULTS

While none of the objective social and physical environmental factors showed associations with PA, subjective parental traffic safety perceptions were positively associated with MVPA and TPA on weekends. Also, preschoolers' participation in organized sports was positively correlated with MVPA (on weekends) and TPA (both on weekends and weekday afternoons).

CONCLUSION

Subjective traffic safety perceptions and participation in organized sports, an indicator and a result of parental support towards PA - i.e. subjective parental perceptions of environmental factors and family-level correlates which are more proximal to preschoolers - might be more central to PA in preschool age than objectively assessed community-level environmental features which tend to be more distal correlates. If replicable, targeting parental perceptions of environmental factors and parental support for PA in preschool age might be powerful leverages for public health policy.

Pet dogs and child physical activity: the role of child-dog attachment

BACKGROUND

Dog ownership has been associated with increased physical activity in children which in turn may mitigate childhood obesity.

OBJECTIVE

To measure the association between child-dog attachment and child physical activity and screen time.

METHODS

Cross-sectional study including 370 children (ages 4-10) who had pet dogs in the home. Parents completed the DartScreen, a web-based screener, before a well-child visit. Screener domains included child body mass index (BMI), physical activity, screen time and dog-related questions. The Companion Animal Bonding Scale (CABS) was used to measure child attachment to the dog. Clinic nurses weighed and measured the children. Associations between CABS, BMI z-score, screen time and physical activity were estimated.

RESULTS

CABS was strongly associated with time spent being active with the dog (F = 22.81, p < 0.0001), but not with BMI z-score or screen time.

CONCLUSIONS

A higher level of child attachment to a pet dog is associated with increased child physical activity.

A Birth Cohort Analysis to Study Dog Walking in Adolescence Shows No Relationship with Objectively Measured Physical Activity

Physical inactivity during childhood and adolescence is a serious health concern. There are few studies of the activity undertaken by adolescents when walking with the family dog, and the effect of this on objectively measured physical activity levels. Objective measures of physical activity using accelerometers were recorded at age 11–12, 13–14, and 15–16 years in the Avon Longitudinal Study of Parents and Children (ALSPAC) (ALSPAC, UK) birth cohort during the 2000s. Family pet ownership was collected retrospectively using a questionnaire at age 18 years, for the ages 7, 11, 13, and 15 years. In addition, approximate frequency per week of walks undertaken with dogs were also reported. Multilevel, multivariable modeling was used to investigate the relationship between dog ownership and dog walking status, and physical activity outcomes. There were a total of 4,373 complete data observations for use in 2,055 children. Reported participation in dog walking tended to increase during adolescence, as did dog ownership. The majority of who own dogs reported walking them either 2–6 times/week (range 39–46%) or never (range 27–37%). A small minority (7–8%) reported walking their dog every day. Most reported never walking any other dog either (94–87%). We found no evidence for an association between dog ownership or reported dog walking, and objectively measured physical activity (counts per minute, P = 0.3, or minutes of moderate-to-vigorous physical activity, P = 0.7) during adolescence. This study provides no evidence to support a relationship between adolescent dog ownership and physical activity, and demonstrates the importance of using objective activity measures and considering dog walking rather than just dog ownership.

Effects of VA Facility Dog on Hospitalized Veterans Seen by a Palliative Care Psychologist: An Innovative Approach to Impacting Stress Indicators

The United States is home to 23 million veterans. In many instances, veterans with serious illness who seek healthcare at the VA receive care from a palliative care service. Animal-assisted intervention (AAI) is gaining attention as a therapeutic stress reducing modality; however, its effects have not been well studied in veterans receiving palliative care in an acute care setting. A crossover repeated-measures study was conducted to examine the effects of an animal-assisted intervention (AAI) in the form of a therapy dog on stress indicators in 25 veterans on the palliative care service at the VA Eastern Colorado Healthcare System in Denver, CO. Veterans had a visit from a therapy dog and the dog's handler, a clinical psychologist (experimental condition) and an unstructured visit with the clinical psychologist alone (control condition). Blood pressure, heart rate, and the salivary biomarkers cortisol, alpha-amylase, and immunoglobulin A were collected before, after, and 30-minutes after both the experimental and control conditions. Significant decreases in cortisol were found when the before time period was compared to the 30-minutes after time period for both the experimental ( p = 0.007) and control condition ( p = 0.036). A significant decrease in HR was also found when the before time period was compared to the 30-minutes after time period for both the experimental ( p = 0.0046) and control ( p = 0.0119) condition. Results of this study supported that a VA facility dog paired with a palliative care psychologist had a measurable impact on salivary cortisol levels and HR in veterans.

Understanding how dogs encourage and motivate walking: cross-sectional findings from RESIDE

Background

Many people live with dogs but not all walk with them regularly. This study examines the demographic and behavioural factors that contribute towards owners reporting having a strong sense of encouragement and motivation to walk provided by their dogs, which we call ‘the Lassie effect’.

Methods

Data was collected from 629 dog owners participating in the RESIDE cross-sectional survey in Perth, Western Australia. Multivariable logistic regression analyses of factors associated with two separate outcome survey items ‘Dog encouragement to walk’ (how often dog encouraged me to go walking in last month) and ‘Dog motivation to walk’ (Having a dog makes me walk more).

Results

Owning a larger dog; having an increased level of attachment to dog; knowing dog enjoys going for a walk; believing walking keeps dog healthy; and having high social support from family to go walking, were positively associated with both outcomes ‘dog encouragement to walk’ and ‘dog motivation to walk’. Conversely, reporting the presence of children at home; that the child is the main person who walks with the dog; and perceiving dog-specific barriers to walking with dog daily; were negatively associated with both outcomes. In addition, ‘Dog motivation to walk’ only was positively associated with a belief walking reduces barking, and negatively with owning a dog that is overweight or a dog that is too old/sick. Reporting that the spouse/partner is main person who walks with the dog was also negatively associated with ‘dog motivation to walk’, as was increased perceived access to public open spaces with dog-supportive features.

Conclusions

There are both dog and owner factors that are associated with an owner’s sense of encouragement, and motivation to walk the dog, which in turn has been found to be associated with dog waking behaviour. These factors may be targeted in future interventions to increase and maintain physical activity levels of both people and pets.

Pet Ownership and the Risk of Dying from Cardiovascular Disease Among Adults Without Major Chronic Medical Conditions

INTRODUCTION

In a recent statement, the American Heart Association stated "There are scant data on pet ownership and survival in people without established cardiovascular disease (CVD)". This study sought to fill this gap.

METHODS

We analyzed nationally representative data of 3964 adults aged ≥50 who were free from major physical illnesses. Pet ownership was assessed at baseline between 1988 and 1994. Vital status was followed through December 31st 2006.

RESULTS

With dogs being most popular pets owned by 22.0 (standard error 0.34) % of the participants, 34.6 % of the study population owned a pet. Pet ownership was associated with low rates of CVD deaths [hazard ratio (HR) = 0.69 (95 % CI 0.45-1.07)] and stroke [0.54 (0.28-1.01)] at borderline significant levels among women. These associations were adjusted for physical activity and largely attributed to having a cat rather than a dog. Among cat owners, the HR of all CVD deaths was 0.62 (0.36-1.05) and the HR of dying from stroke was 0.22 (0.07-0.68) compared with non-cat owners. The corresponding HRs among dog owners were 0.82 (0.51-1.34) and 0.76 (0.34-1.71) respectively. No similar associations were observed among men. The hazard of dying from hypertension was not associated with pet ownership for both men and women.

CONCLUSIONS

Owning a cat rather than a dog was significantly associated with a reduced hazard of dying from CVD events, in particular, stroke. The protection pets confer may not be from physical activities, but possibly due to personality of the pet owners or stress-relieving effects of animal companionship.

Does pet-keeping modify the association of delivery mode with offspring body size?

Caesarean-section (CS) delivery increases risk of childhood obesity, and is associated with a distinct early-life gut microbiome, which may contribute to obesity. Household pets may alter human gut microbiome composition. We examined if pet-keeping modified the association of CS with obesity at age 2 years in 639 Wayne County Health, Environment, Allergy and Asthma Longitudinal Study birth cohort participants. Pet-keeping was defined as having a dog or cat (indoors ≥1 h/day) at child age 2 years. We used logistic regression to test for an interaction between CS and pet-keeping with obesity (BMI ≥ 95th percentile) at age 2 years, adjusted for maternal obesity. A total of 328 (51.3 %) children were male; 367 (57.4 %) were African American; 228 (35.7 %) were born by CS; and 55 (8.6 %) were obese. After adjusting for maternal obesity, CS-born children had a non-significant (P = 0.25) but elevated 1.4 (95 % CI 0.8, 2.5) higher odds of obesity compared to those born vaginally. There was evidence of effect modification between current pet-keeping and delivery mode with obesity at age 2 years (interaction P = 0.054). Compared to children born vaginally without a pet currently in the home, children born via CS without a pet currently in the home had a statistically significant (P = 0.043) higher odds (odds ratio 2.00; 95 % CI 1.02, 3.93) of being obese at age 2 years. Pets modified the CS-BMI relationship; whether the underlying mechanism is through effects on environmental or gut microbiome requires specific investigation.

Dog ownership status and self-assessed health, life-style and habitual physical activity in chronic hemodialysis patients

Introduction The Statement from the American Heart Association has emphasized a need for novel strategies that can reduce the risk of cardiovascular disease (CVD). Taking a dog for a walk forces its owner to take physical activity. Several studies have explored the relationship between pet ownership and CVD and most reported benefits. This issue has not been investigated in dialysis patients. The aim of the study was to analyze the influence of pet ownership on health and physical activity in hemodialysis patients. Methods 270 chronic hemodialysis patients (172 male, 98 female, mean age 62.7 ± 14.0 years, hemodialysis vintage 4 ± 5 years) took part in the survey focused on their general health and physical activity. Findings Two hundred nineteen (81%) patients were mobile. One hundred sixteen participants had dog at home (43%). An additional physical activity was reported by 46 dog owners (40%) compared with 34 (23%) of nonowners (P = 0.002). Patients who often go for a walk were more often pet owners 49 (57%) than nonowners (n = 37, 43%; P = 0.004). Pet owners were younger (58.3 ± 13.6 vs. 66 ± 13.5 years). Body mass index (BMI) was similar. Patients with BMI from upper tertile (>27.5 kg/m(2) ) and from lower (<23.9) were more often dog owners than from the middle (52.9%, 43.7%, and 31.4%). Dog owners were on dialysis for longer time (5.0 ± 6.5 vs. 3.5 ± 3.7 years; P = 0.02). Discussion Dog ownership appears to positively influence the level of physical activity. Age but not time on dialysis seems to be the most important factor that influences a decision to own a pet and undertake physical activity.

Dog walking among adolescents: Correlates and contribution to physical activity

PURPOSE

To assess the association of dog walking with adolescents' moderate-to-vigorous physical activity (MVPA) and body mass index (BMI), and identify correlates of dog walking.

METHODS/DESIGN

Participants were 12-17year-olds (n=925) from the Baltimore, MD and Seattle, WA regions. Differences in accelerometer-assessed minutes/day of MVPA and self-reported BMI (percentile) were compared among adolescents (1) without a dog (n=441) and those with a dog who (2) did (≥1days/week, n=300) or (3) did not (n=184) walk it. Correlates of (1) dog walking (any vs. none) among adolescents with dogs (n=484), and (2) days/week of dog walking among dog walkers (n=300) were investigated. Potential correlates included: demographic, psychosocial, home environment, perceived neighborhood environment, and objective neighborhood environment factors.

RESULTS

52% of adolescents lived in a household with a dog, and 62% of those reported dog walking ≥1day/week. Dog walkers had 4-5 more minutes/day of MVPA than non-dog-walkers and non-dog-owners. BMI was not associated with dog walking or ownership. Among households with dogs, adolescents who lived in objectively walkable neighborhoods were 12% more likely to walk their dog than those in less walkable neighborhoods. Among dog walkers, having a multi-family home, college-educated parent, lower perceived traffic safety, higher street connectivity and less mixed use were related to more days/week of dog walking.

CONCLUSIONS

Dog walkers had 7-8% more minutes/day of MVPA than non-dog walkers, and correlates of dog walking were found at multiple levels of influence. Results suggest multilevel interventions that include both environmental and psychosocial components to increase dog walking should be evaluated.

Pet Dogs and Children's Health: Opportunities for Chronic Disease Prevention?

Introduction

Positive associations between having a pet dog and adult health outcomes have been documented; however, little evidence exists regarding the benefits of pet dogs for young children. This study investigates the hypothesis that pet dogs are positively associated with healthy weight and mental health among children.

Methods

This cross-sectional study accrued a consecutive sample of children over 18 months in a pediatric primary care setting. The study enrolled 643 children (mean age, 6.7 years); 96% were white, 45% were female, 56% were privately insured, and 58% had pet dogs in the home. Before an annual visit, parents of children aged 4 to 10 years completed the DartScreen, a comprehensive Web-based health risk screener administered using an electronic tablet. The screener domains were child body mass index (BMI), physical activity, screen time, mental health, and pet-related questions.

Results

Children with and children without pet dogs did not differ in BMI (P = .80), screen time of 2 hours or less (P = 0.99), or physical activity (P = .07). A lower percentage of children with dogs (12%) met the clinical cut-off value of Screen for Child Anxiety and Related Disorders (SCARED-5) of 3 or more, compared with children without dogs (21%, P = .002). The mean SCARED-5 score was lower among children with dogs (1.13) compared with children without dogs (1.40; P = .01). This relationship was retained in multivariate analysis after controlling for several covariates.

Conclusions

Having a pet dog in the home was associated with a decreased probability of childhood anxiety. Future studies need to establish whether this relationship is causal and, if so, how pet dogs alleviate childhood anxiety.

Not Just “A Walking the Dog”: Dog Walking and Pet Play and Their Association with Recommended Physical Activity among Adolescents

Purpose.

To examine the role of pet play and dog walking in children's and adolescents' leisure time, and the relationship between these activities and physical activity.

Design.

The study design was observational.

Setting.

The study setting was metropolitan Perth and nonmetropolitan regions in Western Australia.

Subjects.

The study included 1097 primary school (mean age, 10.1 years; SD, 1.6 years) and 657 secondary school (mean age, 14.0 years; SD, 1.3 years) students.

Measures.

Validated measures of total physical activity, dog walking, and pet play activity (prevalence and time) were calculated.

Analysis.

Generalized linear models tested for differences between proportions, while adjusting for socioeconomic status, age, and school-level clustering.

Results.

Approximately one third of primary school and one quarter of secondary school students reported that they walked the dog at least once in the last week. Pet play was the most common play activity for primary and secondary school girls, and the second and third most popular play activity for secondary and primary school boys, respectively. Secondary school students who walked the dog or played with pets spent an average of 1 hour per week on each activity, and they were significantly more likely (p < .005) to meet national physical activity recommendations than secondary school students not reporting these activities.

Conclusion.

Given the significant proportion of young people who frequently engage in dog walking and pet play, and the high level of pet ownership in many Western countries, promotion of these activities to support young people's health is warranted.

Physical activity in adolescents with an orthopaedic limitation: a review of the literature

Nine out of 10 adolescents fail to achieve the Healthy People 2020 recommended levels of aerobic and muscle-strengthening physical activity(J. E. Fulton et al., 2011).Whereas all adolescents constitute a vulnerable population because of their minimal physical activity, those with an orthopaedic limitation, such as slipped capitol femoral epiphyses, are at greater risk despite sharing characteristics with the general adolescent population such as normal cognition and independent ambulation. Twenty articles are reviewed describing components of effective physical activity interventions for adolescents aged 10-19 and their applicability to the target population of those with an orthopaedic limitation. Although physical activity interventions for adolescents with an orthopaedic limitation receive limited discussion in the literature, physical capability, belief in ability, and nontraditional activities, including dog-walking, are identified as behavioral facilitators.

Barriers and facilitators to dog walking in New England

Dog walking may increase physical activity among dogs and their owners. Understanding barriers and facilitators to walking the dog is critical to developing interventions to increase dog walking. This study aimed to confirm previously identified barriers and facilitators of dog walking, and to identify unique factors that may be relevant to dog walking in cities with variable weather. This mixed methods study used focus groups to identify barriers and facilitators associated with dog walking and a survey to examine which factors were associated with dog walking. Focus group participants described barriers, such as lack of time, weather, lack of places to walk and the dog's bad behaviour. Facilitators included enjoyment, dog walking norms (defined as the participant's perception of how much the veterinarian, other dog owners, and their family think they should walk the dog), and socialisation opportunities. A hierarchical regression analysis of survey data revealed that the participant's perception of dog walking norms was associated with increased frequency and duration of dog walking, while weather, work and family commitment barriers were associated with a reduced frequency and duration of dog walking. Family, community and veterinarian dog walking norms, inclement weather, and lack of time due to work obligations emerged as important correlates of dog walking. Interventions that aim to increase physical activity by encouraging dog walking may benefit from incorporating strategies that address facilitators (family support) and barriers (time and weather) to walking the dog.

Dog walking is associated with more outdoor play and independent mobility for children

OBJECTIVE

Dog ownership is positively associated with children's physical activity. It is plausible that dog-facilitated activity rather than dog ownership per se encourages children's physical activity behaviors. We examined relationships between dog walking and children's physical activity, and outdoor play and independent mobility.

METHOD

Cross-sectional survey data from the 2007 Perth (Western Australia) TRavel, Environment, and Kids (TREK) project were analyzed for 727 10-12 year olds with a family dog. Weekly minutes of overall physical activity and walking, local walking and outdoor play were collected from children and parents. Children's weekly pedometer steps were measured. Independent mobility was determined by active independent travel to 15 local destinations.

RESULTS

Overall, 55% of children walked their dog. After adjustment, more dog walkers than non-dog walkers walked in the neighborhood (75% vs. 47%), played in the street (60% vs. 45%) and played in the yard (91% vs. 84%) (all p ≤ 0.05). Dog walkers were more independently mobile than non-dog walkers (p ≤ 0.001). Dog walking status was not associated with overall physical activity, walking, or pedometer steps (p>0.05).

CONCLUSIONS

Dog-facilitated play and physical activity can be an effective strategy for increasing children's physical activity. Dog walking may provide a readily accessible and safe option for improving levels of independent mobility.

How might we increase physical activity through dog walking?: A comprehensive review of dog walking correlates

BACKGROUND

Physical inactivity and sedentary behaviour are major threats to population health. A considerable proportion of people own dogs, and there is good evidence that dog ownership is associated with higher levels of physical activity. However not all owners walk their dogs regularly. This paper comprehensively reviews the evidence for correlates of dog walking so that effective interventions may be designed to increase the physical activity of dog owners.

METHODS

Published findings from 1990-2012 in both the human and veterinary literature were collated and reviewed for evidence of factors associated with objective and self-reported measures of dog walking behaviour, or reported perceptions about dog walking. Study designs included cross-sectional observational, trials and qualitative interviews.

RESULTS

There is good evidence that the strength of the dog-owner relationship, through a sense of obligation to walk the dog, and the perceived support and motivation a dog provides for walking, is strongly associated with increased walking. The perceived exercise requirements of the dog may also be a modifiable point for intervention. In addition, access to suitable walking areas with dog supportive features that fulfil dog needs such as off-leash exercise, and that also encourage human social interaction, may be incentivising.

CONCLUSION

Current evidence suggests that dog walking may be most effectively encouraged through targeting the dog-owner relationship and by providing dog-supportive physical environments. More research is required to investigate the influence of individual owner and dog factors on 'intention' to walk the dog as well as the influence of human social interaction whilst walking a dog. The effects of policy and cultural practices relating to dog ownership and walking should also be investigated. Future studies must be of a higher quality methodological design, including accounting for the effects of confounding between variables, and longitudinal designs and testing of interventions in a controlled design in order to infer causality.

Children, parents and pets exercising together (CPET): exploratory randomised controlled trial

BACKGROUND

Levels of physical activity (PA) in UK children are much lower than recommended and novel approaches to its promotion are needed. The Children, Parents and Pets Exercising Together (CPET) study is the first exploratory randomised controlled trial (RCT) to develop and evaluate an intervention aimed at dog-based PA promotion in families. CPET aimed to assess the feasibility, acceptability and potential efficacy of a theory-driven, family-based, dog walking intervention for 9-11 year olds.

METHODS

Twenty-eight families were allocated randomly to either receive a 10-week dog based PA intervention or to a control group. Families in the intervention group were motivated and supported to increase the frequency, intensity and duration of dog walking using a number of behaviour change techniques. Parents in the intervention group were asked to complete a short study exit questionnaire. In addition, focus groups with parents and children in the intervention group, and with key stakeholders were undertaken. The primary outcome measure was 10 week change in total volume of PA using the mean accelerometer count per minute (cpm). Intervention and control groups were compared using analysis of covariance. Analysis was performed on an intention to treat basis.

RESULTS

Twenty five families were retained at follow up (89%) and 97% of all outcome data were collected at baseline and follow up. Thirteen of 14 (93%) intervention group parents available at follow up completed the study exit questionnaire and noted that study outcome measures were acceptable. There was a mean difference in child total volume of PA of 27 cpm (95% CI -70, 123) and -3 cpm (95% CI -60, 54) for intervention and control group children, respectively. This was not statistically significant. Approximately 21% of dog walking time for parents and 39% of dog walking time for children was moderate-vigorous PA.

CONCLUSIONS

The acceptability of the CPET intervention and outcome measures was high. Using pet dogs as the agent of lifestyle change in PA interventions in children and their parents is both feasible and acceptable, but did not result in a significant increase in child PA in this exploratory trial.

Understanding the relationship between dog ownership and children's physical activity and sedentary behaviour

BACKGROUND

Dog ownership is a catalyst for physical activity in adults. Given 50-70% of Australian households with children have a dog, dog-facilitated physical activity may be an effective way to increase physical activity and decrease child obesity.

OBJECTIVE

We hypothesized that children with a family dog walk more, are more physically active and are more likely to achieve recommended levels of weekly physical activity compared with children who do not have a dog.

METHOD

Cross-sectional data from the Western Australian TRravel, Environment, and Kids project (TREK) were analyzed for 1218 children aged 10-12 years. Individual and environment factors, child physical activity, walking, screen use, sedentary behaviour and dog ownership status was collected from child and parent questionnaires. Children's height and weight were measured.

RESULTS

Approximately 60% of children had a family dog. Dog ownership was associated with, on average, 29 more minutes of walking and 142 more minutes of physical activity per week (P ≤ 0.01). After adjustment, children with a dog were 49% more likely to achieve the recommended level of weekly physical activity (420 min) and 32% more likely to have walked in their neighbourhood in the last week, compared with non-dog owners (P ≤ 0.05). These relationships varied by gender. Dog ownership was not associated with screen use or weight status.

CONCLUSIONS

Dog ownership was associated with walking and physical activity, but not screen use or weight status. Within dog-owning families, the promotion of walking and active play with a dog may be a strategy to increase children's physical activity.

A cross-sectional study of frequency and factors associated with dog walking in 9-10 year old children in Liverpool, UK

Background

Owning a pet dog could potentially improve child health through encouraging participation in physical activity, through dog walking. However, evidence to support this is limited and conflicting. In particular, little is known about children’s participation in dog walking and factors that may be associated with this. The objective of this study was to describe the participation of children in dog walking, including their own and those belonging to somebody else, and investigate factors associated with regular walking with their own pet dog.

Methods

Primary school children (n=1021, 9–10 years) from a deprived area of Liverpool were surveyed during a ‘fitness fun day’ as part of the SportsLinx project. The ‘Child Lifestyle and Pets’ survey included questions about pet ownership, pet attachment, and dog walking. Multivariable logistic regression models were used to investigate factors associated with walking any dog, or their own dog, several times a day or more, including level of attachment to the dog, dog type, and sociodemographic factors.

Results

Overall, 15.4% of children reported walking with any dog (their own or belonging to a friend or family member) ≥ once daily, 14.1% several times a week, 27.6% ≤ once a week, and 42.8% never. Dog owning children (37.1% of the population) more often reported dog walking ‘several times a week or more’ (OR=12.30, 95% CI=8.10-18.69, P<0.001) compared to those without a dog, but were less likely to report other walking without a dog. The majority (59.3%) of dog owning children indicated that they usually walked their dog, with 34.6% reporting that they walked their dog ≥ once daily. Attachment score was highly associated with the child reporting walking their dog (lower score=higher attachment; OR=0.93, 95% CI=0.89-0.96, P<0.001). There was no evidence that gender, ethnicity, sibling status or deprivation score was associated with dog walking. Children that reported owning Pit Bulls were more likely to report friends walking with their dog than those owning non-Pit bull types (OR=10.01, 95% CI=1.52-65.76, P=0.02, respectively).

Conclusions

Promotion of supervised walking of suitable pet dogs may be an opportunity for increasing physical activity in 9–10 year old children. The identification of stronger attachment to dogs regularly walked is similar to findings in adult studies.

Children, parents, and pets exercising together (CPET) randomised controlled trial: study rationale, design, and methods

BACKGROUND

Objectively measured physical activity is low in British children, and declines as childhood progresses. Observational studies suggest that dog-walking might be a useful approach to physical activity promotion in children and adults, but there are no published public health interventions based on dog-walking with children. The Children, Parents, and Pets Exercising Together Study aims to develop and evaluate a theory driven, generalisable, family-based, dog walking intervention for 9-11 year olds.

METHODS/DESIGN

The Children, Parents, and Pets Exercising Together Study is an exploratory, assessor-blinded, randomised controlled trial as defined in the UK MRC Framework on the development and evaluation of complex interventions in public health. The trial will follow CONSORT guidance. Approximately 40 dog-owning families will be allocated randomly in a ratio of 1.5:1 to receive a simple behavioural intervention lasting for 10 weeks or to a 'waiting list' control group. The primary outcome is change in objectively measured child physical activity using Actigraph accelerometry. Secondary outcomes in the child, included in part to shape a future more definitive randomised controlled trial, are: total time spent sedentary and patterning of sedentary behaviour (Actigraph accelerometry); body composition and bone health from dual energy x-ray absorptiometry; body weight, height and BMI; and finally, health-related quality of life using the PedsQL. Secondary outcomes in parents and dogs are: changes in body weight; changes in Actigraph accelerometry measured physical activity and sedentary behaviour. Process evaluation will consist of assessment of simultaneous child, parent, and dog accelerometry data and brief interviews with participating families.

DISCUSSION

The Children, Parents, and Pets Exercising Together trial should be the first randomised controlled study to establish and evaluate an intervention aimed at dog-based physical activity promotion in families. It should advance our understanding of whether and how to use pet dogs to promote physical activity and/or to reduce sedentary behaviour in children and adults. The trial is intended to lead to a subsequent more definitive randomised controlled trial, and the work should inform future dog-based public health interventions such as secondary prevention interventions in children or adults.

Is childhood obesity influenced by dog ownership? No cross-sectional or longitudinal evidence

OBJECTIVE

To examine whether dog ownership is associated with lower risk of childhood obesity.

METHODS

Cross-sectional study of 7,759 children at age 7 years in the Avon Longitudinal Study of Parents and Children (ALSPAC) in the UK. In addition, longitudinal analyses were conducted between age 7 and 9 years. BMI at age 7 and 9 years was calculated from clinic-measured weight and height and standardised in reference to 1990 UK data. Dog ownership data were collected by carer questionnaire at various time points.

RESULTS

After adjustment for confounding factors associated with dog ownership or obesity, there was no evidence of an association between obesity and dog ownership at 7 years OR = 1.18, 95% confidence interval = 0.88-1.59, p = 0.27), or dog ownership history. There was also no evidence for an effect of dog ownership on BMI change between 7 and 9 years, nor acquisition of a dog on the change in weight status of obese children between 7 and 9 years.

CONCLUSION

This study provides no evidence for a protective effect of dog ownership on the development of childhood obesity. Further investigation is required to determine the impact of dog ownership on physical activity in overweight and obese children.

Using formative research to develop CHANGE!: a curriculum-based physical activity promoting intervention

BACKGROUND

Low childhood physical activity levels are currently one of the most pressing public health concerns. Numerous school-based physical activity interventions have been conducted with varied success. Identifying effective child-based physical activity interventions are warranted. The purpose of this formative study was to elicit subjective views of children, their parents, and teachers about physical activity to inform the design of the CHANGE! (Children's Health, Activity, and Nutrition: Get Educated!) intervention programme.

METHODS

Semi-structured mixed-gender interviews (group and individual) were conducted in 11 primary schools, stratified by socioeconomic status, with 60 children aged 9-10 years (24 boys, 36 girls), 33 parents (4 male, 29 female) and 10 teachers (4 male, 6 female). Questions for interviews were structured around the PRECEDE stage of the PRECEDE-PROCEDE model and addressed knowledge, attitudes and beliefs towards physical activity, as well as views on barriers to participation. All data were transcribed verbatim. Pen profiles were constructed from the transcripts in a deductive manner using the Youth Physical Activity Promotion Model framework. The profiles represented analysis outcomes via a diagram of key emergent themes.

RESULTS

Analyses revealed an understanding of the relationship between physical activity and health, although some children had limited understanding of what constitutes physical activity. Views elicited by children and parents were generally consistent. Fun, enjoyment and social support were important predictors of physical activity participation, though several barriers such as lack of parental support were identified across all group interviews. The perception of family invested time was positively linked to physical activity engagement.

CONCLUSIONS

Families have a powerful and important role in promoting health-enhancing behaviours. Involvement of parents and the whole family is a strategy that could be significant to increase children's physical activity levels. Addressing various perceived barriers to such behaviours therefore, remains imperative.
