Where does physical activity fit into preschool postpandemic? A qualitative exploration with parents, teachers and administrators

ObjectivesDuring the preschool years, children depend on adult caregivers to provide opportunities for physical activity (PA). Research has focused on measuring PA in preschool, as well as barriers and facilitators...

KIJANI App to Promote Physical Activity in Children and Adolescents: Protocol for a Mixed Method Evaluation.

The prevalence of physical inactivity among children and adolescents is alarmingly high despite the well-documented and comprehensive benefits of regular physical activity (PA). Therefore, PA promotion should start early in childhood and adolescence. Although reducing recreational screen time in children and adolescents is an urgent concern, digital approaches have the potential to make activity promotion attractive and age appropriate for the target group. KIJANI is a mobile app approach to promote PA in children and adolescents via gamification and augmented reality. This study protocol aims to describe the KIJANI intervention in detail, as well as the evaluation approach. KIJANI is based on the concept that virtual coins can be earned through PA, for example, in the form of a collected step count. With these coins, in turn, blocks can be bought, which can be used to create virtual buildings and integrate them into the player's real-world environment via augmented reality. PA of users is detected via accelerometers integrated into the smartphones. KIJANI can be played at predefined play locations that were comprehensively identified as safe, child-friendly, and attractive for PA by the target group in a partner project. The evaluation process will be divided into 2 different stages. The phase-I evaluation will be a mixed methods approach with one-on-one semistructured interviews and questionnaires to evaluate the user experience and receive feedback from the target group. After the implementation of results and feedback from the target group, the phase-II evaluation will proceed in the form of a 2-arm randomized controlled trial, in which the effectiveness of KIJANI will be assessed via objectively measured PA as well as questionnaires. The study received ethical approval from the ethical board of the Technical University of Munich. Participants for the phase-I evaluation are currently being recruited. The study will help to determine the efficacy, applicability, and user experience of a gamified activity promotion application in children and adolescents. Overall, digital health approaches provide easy and wide reachability at low cost and are age appropriate and attractive for the target group of adolescents. Strategies have to be developed to apply digital health approaches in the best possible way for activity promotion. DERR1-10.2196/55156.

Factors associated with out-of-school physical activity among Chinese children and adolescents: A stratified cross-sectional study

ObjectiveThis observational study examined the factors associated with the physical activity (PA) of children and adolescents outside of school within the framework of Problem Behavior Theory (PBT). MethodsThis cross-sectional study obtained data from 6528 children and adolescents aged 6–16 years recruited from ten schools in Shanghai, China. The questionnaire measured out-of-school PA and PBT-based correlates. A series of multiple linear regressions were used to explore the factors influencing children and adolescents' out-of-school PA separately. Structural equation modeling (SEM) was used to explore the association between the three systems of PBT and out-of-school PA. ResultsHigher intrinsic motivation is positively associated with increased PA for children (b = 1.038, 95%CI: 0.897–1.180) and adolescents (b = 1.207, 95%CI: 0.890–1.524). Greater frequency of parental involvement in PA correlates with elevated PA for both children (b = 2.859, 95%CI: 2.147–3.572) and adolescents (b = 2.147, 95%CI: 0.311–3.983). In children, increased use of community exercise areas or facilities (b = 1.705, 95%CI: 0.234–3.176) and higher recreational screen time (b = 9.732, 95%CI: 5.614–13.850) are associated with higher PA. The SEM showed that factors of the personality system had a significant direct effect on out-of-school PA among children and adolescents, and factors of the behavior system also had a significant effect on children. ConclusionsOur findings suggest that the personality system, particularly intrinsic motivation, is important in promoting out-of-school PA in children and adolescents. For children, modifiable health behaviors in the behavior system can similarly influence PA.

Sports participation in childhood and adolescence and physical activity intensity in adulthood.

The aim of the present study was to analyze the association between sports participation in childhood and adolescence and the practice of physical activity at different intensities in adulthood, and to verify if some sports participation characteristics such as number of sports; type of sport (individual, collective or a combination of both) and total estimated sports participation time are associated with the different physical activity intensities in adulthood. This is a cross-sectional study. This study included 129 young adults of both sexes aged 18-25 years. Sports participation in childhood (7-10 years) and adolescence (11-17 years) was retrospectively estimated through specific questionnaire. Light, moderate, vigorous and moderate to vigorous intensity physical activity was objectively estimated by accelerometers. To verify the association between SP in childhood and adolescence and BP intensities in adults, multiple linear regression was adopted, with 5% significance. Analyses showed that, in females, sports participation in childhood (β = 0.315; R2 = 0.14; P = 0.020) and persistence in sports participation (β = 0.364; R2 = 0.18; P = 0.007) were positive predictors of vigorous physical activity in adulthood. In addition, the comparison according to the specificities of the sport practice, indicated that participation in two or more sports in childhood, one sport and collective sports in adolescence and at least one year of sports participation throughout childhood and adolescence were associated with longer time in vigorous physical activity intensity and MVPA (minutes/day) in adult females (P < 0.05). It could be concluded that sports participation indicators in childhood and adolescence were considered predictors of vigorous physical activity in adult females. In addition, number of sports, type of sport and practice time in childhood and adolescence seem to predict vigorous and moderate to vigorous levels of physical activity for adult females.

Exploring Physical Activity in Children and Adolescents with Disabilities: A Bibliometric Review of Current Status, Guidelines, Perceived Barriers, and Facilitators and Future Directions.

Physical activity contributes to both physiological and psychosocial benefits for children and adolescents with disabilities. However, the prevalence of physical inactivity is notably higher among disabled young people compared to their healthy peers. Despite this, there is a lack of constructed knowledge structure, evolutionary path, research hotspots, and frontiers in studies related to physical activity in young people with disabilities. The literature related to the research of physical activity in children and adolescents with disabilities was retrieved from the core collection of the Web of Science. The annual publication numbers and the timing, frequency, and centrality of the co-occurrence network with respect to journals, countries, institutions, authors, references, and keywords were analyzed. Additionally, clustering analysis and burst analysis were performed on the references and keywords. All analyses were conducted using CiteSpace. A total of 1308 related articles were included. The knowledge structure of research on the physical activity of disabled children and adolescents, including annual publication numbers, influencing journals, countries, institutions, authors, references, and keywords along with their respective collaborative networks, has been constructed. Furthermore, the research foundation, current hot topics, and research frontiers have been identified by analyzing references and keywords. Current research hotspots include interventions, therapies, and programs aimed at enhancing specific skills, as well as addressing the satisfaction of competence to improve motivation and the effectiveness of physical activity. There is also a focus on the development of scales for quantitative studies. Future directions may be toward personalized interventions or programs to enhance physical activity levels among youth with disabilities.

The cross-sectional association of parental psychosocial status with children's Body Mass Index z-score and the mediating role of children's energy balance behaviors - the ABCD Study.

Investigate the cross-sectional association between the psychosocial status of mothers and fathers and the BMI z-scores of their 10 to 12-year-old children. Explore whether this association is mediated by children's diet, physical activity, screen time and sleep. Analyze the moderating effect of the educational levels of both the mother and father on the association. In a cross-sectional study design, children's height and weight were measured following a standardized protocol. Parents completed the validated Depression Anxiety and Stress questionnaire, while diet quality, sports participation, time spent in bed and screen time were assessed through child-report using previously validated questions. The data for this study were obtained from the Amsterdam Born Children and their Development study, involving children aged 10 to 12 years and both of their parents (N = 1315). The majority, 80%, of the parents were highly educated and born in the Netherlands, and 68% of the children had a healthy BMI. Maternal or paternal psychosocial status was not significantly associated with children's BMI z-score (maternal β -0.0037; 95% CI: -0.008 to 0.0007, paternal β 0.0028; 95% CI: -0.007 to 0.002). Screen time mediated the association between paternal psychosocial status and children's BMI z-score (β = 0.010, 95% CI: 0.002; 0.020). Children's diet, physical activity, and sleep did not mediate the association between paternal psychosocial status and children's BMI z-score. Parental educational level was not a moderator. This research is unique in including four energy balance behaviors and including both mothers and fathers' psychosocial status. Children withfathers experiencing poorer psychosocial status engaged in more screen time which partly explained their higher BMI z-score.

Physical Activity and Sports for Children With Juvenile Idiopathic Arthritis

Juvenile idiopathic arthritis (JIA) is the most common rheumatic disease of childhood, presenting clinically as inflammatory arthritis in children younger than 16 years. To date, while evidence supports physical activity for children with JIA, there is limited evidence on the recommended approach to physical activity and sports participation in this population, and no single structured therapeutic exercise program has been established as best practice. This review article presents what is known on the management of physical activity in children with JIA, including recommendations from the pediatric rheumatology and rehabilitation literature, where available, for sports participation, structured therapeutic exercise programs, and return to activity.

Factors impacting physical activity among post-treatment pediatric cancer survivors with overweight and obesity.

Pediatric cancer survivors (PCS) with overweight and obesity are at risk for various secondary chronic diseases. Although previous research has found physical activity (PA) as beneficial after treatment, the PA levels are low among PCS, highlighting the need for lifestyle interventions targeting PA. A secondary analysis of preliminary baseline data from a multi-site trial, NOURISH-T + , a healthy lifestyle intervention for PCS with overweight and obesity, and their caregivers, was conducted to assess factors related to PCS PA (i.e., moderate to vigorous intensity PA, MVPA). Kendall's Tau-b was used to assess correlations between PCS MVPA, health and treatment-related factors, and caregivers' sedentary behavior and MVPA. Wilcoxon Signed Ranks Test was used to assess the differences between PCS and caregiver sedentary behavior and MVPA. A multiple linear regression analysis was performed to determine predictors of PCS MVPA. Seventy-three PCS-caregiver dyads were included in this analysis (N = 146). Many of the PCS were female, diagnosed with Acute Lymphoblastic Leukemia, stage 1, with a mean body mass index (BMI) percentile of 94.4 ± 4.7. Caregivers were female and parents to the PCS. Significant correlations were found between PCS MVPA, time since treatment, PCS weight change since COVID, caregiver sedentary behavior and MVPA. Significant differences were observed between PCS and caregiver sedentary behavior and MVPA. Household income, radiation treatment, and caregiver MVPA were significant predictors of PCS MVPA. Conclusions: Demographics, cancer treatment type, and caregiver role modeling are important factors to consider when developing future lifestyle interventions for PCS. (NCT04656496, registered 12-07-2020). • Parents/caregivers are presumed to be a potential influence on their children's physical activity What is new: • Parents/caregivers' moderate-to-vigorous physical activity is the strongest predictor of their children's (pediatric cancer survivors') physical activity.

The Odds of Meeting Physical Activity Guidelines in Children Receiving School-Based Fitness Testing Awards: NHANES 2013–2016

Fitness testing and awards have been used in physical education classrooms for over 50 years. While their initial intention was to promote physical activity engagement, analyses show they are not achieving their goal. This article highlights fitness testing awards and the need to re-evaluate how they can help meet the physical activity guidelines for children ages 5 to 15 years. A cross-sectional secondary data analysis was employed using data from the 2013-2016 National Health and Nutrition Examination Survey (N = 3973). Analysis results showed that receiving fitness awards is not associated with children meeting physical activity guidelines. It is thus important for physical education teachers and school administrators to adopt and implement process-based fitness testing awards (e.g., giving awards for an individual's fitness-behavior goal achievement or improvement) along with performance-based fitness awards to enhance children's physical activity levels.

Physical activity advice for children and young people

Unfortunately, only 47.2% of children and young people in the UK are currently meeting the chief medical officer’s physical activity guidelines of 60 minutes daily, with 30.1% of children doing less than 30 minutes daily. Reduced physical activity in children is a significant contributor to childhood obesity, a growing paediatric pandemic with 1-in-3 children overweight or obese by the time they leave primary school. The long-term health implications of this and the additional burden on health services are already widely apparent. It is important for GPs and primary care staff to understand the current UK recommendations and evidence on childhood physical activity to empower their support of early engagement of children with measures to improve levels of physical activity. An understanding of childhood obesity is also important. At the other end of the spectrum elite children’s sport is becoming increasingly competitive and injuries in developing children can lead to lifelong complications and injury recurrence. It is, therefore, important to understand how much and what types of exercise and training are safe in the paediatric population.

The effects of COVID-19 on the Physical Activity and Recreational Screen Time among Chinese children and adolescents

BackgroundThe lack of Physical Activity (PA) and prolonged Recreational Screen Time (RST) among children and adolescents has been exacerbated during the COVID-19 pandemic, causing this issue to escalate into a crucial public health concern. This study aims to investigate the trends in PA and RST among Chinese children and adolescents from 2019 to 2022, thereby analyzing the short-term and long-term effects of the pandemic on PA and RST among Chinese children and adolescents. MethodsA nationally representative sample of Chinese primary, middle, and high school students was surveyed annually between September and December from 2019 to 2022 using a consistent set of questionnaires. Trends in PA and RST across different school levels, genders, areas (urban/rural), and regions (north/south) were analyzed using Segmented Linear Regression. ResultsFrom 2019 to 2022, the PA and RST of children and adolescents displayed an inverted U-shaped trend, initially increasing and subsequently declining. Specifically, from 2019 to 2021, the PA of children and adolescents significantly increased but dramatically declined from 2021 to 2022. This trend in PA is more pronounced among primary, male, urban, and northern children and adolescent. The RST of children and adolescents increased from 2019 to 2020 but significantly decreased from 2020 to 2022. This trend in RST is more pronounced among primary, urban, and southern children and adolescent. ConclusionsThis research unveils the effects of the pandemic on PA and RST in children and adolescents, suggesting short-term beneficial and long-term adverse effects on PA and short-term adverse and long-term beneficial effects on RST. These findings provide a foundation for formulating policies related to children and adolescents' PA and RST during the pandemic.

Longitudinal Associations Between Physical Activity and Depressive Symptoms in Chinese Children: Evidence from the Tongji Mental Health Cohort Study.

We aimed to examine the associations between depressive symptoms and physical activity parameters (e.g., intensity, frequency, and duration) among Chinese school-aged children. Participants in this study were extracted from the Tongji Mental Health Cohort Study. The baseline survey was conducted in June 2020 involving 2588 school-aged children from two primary schools in Hubei Province, China. A total of 2435 children were followed up successfully in December 2020. The Children's Depression Inventory Short Form (CDI-S) was applied to evaluate depressive symptoms among school-aged children. The Physical Activity Rating Scale-3 (PARS-3) was adopted to estimate children's physical activity parameters including the intensity, frequency, and duration. Generalized estimation equation models were used to explore the longitudinal associations between physical activity and depressive symptoms among school-aged children. Engaging in moderate levels of physical activity (OR, 0.800; 95%CI, 0.692-0.924) or high levels of physical activity (OR, 0.808; 95%CI, 0.689-0.947) in the baseline survey was associated with a reduced risk of developing depressive symptoms in the follow-up survey compared with children engaging in low levels of physical activity. Stratified analyses revealed that the associations between physical activity and depressive symptoms exhibited a significant correlation among boys and children in the older age group (11-12years). Our findings showed that engaging in physical activity more than once a week, with each session lasting 20min or longer, was related to significant reductions in depressive symptoms by 43.8% and 22.3%, respectively. Self-reported physical activity is positively associated with improved mental health among Chinese school-aged children, especially when considering parameters such as frequency and duration. The association between vigorous-intensity physical activity and depressive symptoms in children should be cautiously interpreted. Future research should continue to explore the effects of vigorous-intensity physical activity on depressive symptoms in children.

Assessment of the Physical Activity of Children with Asthma Bronchiale.

Physical activity is an especially important part of everyday life for children with chronic diseases. The aim of the study was to show whether asthma is a barrier to physical activity in our society. The correlations between the severity of the disease, body mass index, and physical activity were analyzed, and parents' opinions on whether children should participate in active sports were assessed. Physical activity of children with asthma was analyzed by questionnaires; 93 parents and their 93 children were involved in the survey. The age of children was 12.6 ± 3.5 years (mean ± SD), 69.9% were boys, 30.1% were girls. A total of 93.4% of the respondents participated in a physical education program and 56.5% also attended sporting activities on a regular basis. In terms of disease severity, 61.2% of the children had mild asthma, 37.6% moderate, and 1.2% severe, and 6.5% of the respondents also stated that their children's illness had been consistently or frequently limiting their performance concerning their school or home duties over the past four weeks. Of the parents surveyed, 12% felt that physical activity was not appropriate in the context of this disease. We concluded that fear of the consequences of physical activity depends largely on education, which should involve parents, teachers, and coaches.

Associations among COVID-19 Family Stress, Family Functioning, and Child Health-Related Quality of Life through Lifestyle Behaviors in Children.

The COVID-19 pandemic has resulted in lasting effects on children, necessitating a thorough understanding of its impact for effective recovery planning. This study investigated the associations among COVID-19 family stress, family functioning, children's lifestyle behaviors (i.e., healthy food intake, unhealthy food intake, physical activity, and screen time), and their health-related quality of life (HRQOL). Data from a 2022 survey of parents with children aged 5 to 12 (mean age of boys: 8.36, mean age of girls: 7.76) in the United States through the online Prolific platform were analyzed using path analysis and gender-based multi-group analysis. The results showed an inverse relationship between family stressors and functioning (β = -0.39, p < 0.05). COVID-19 family stress was negatively related to child physical HRQOL (β = -0.20, p < 0.05) but not psychosocial HRQOL. Family functioning showed a positive relation with child healthy food intake (β = 0.26, p < 0.05) and a negative relation with unhealthy diet consumption (β = -0.27, p < 0.05), while no significant associations were found with child physical activity and screen time. Family functioning was indirectly associated with both types of HRQOL through the child's eating patterns. These relationships were more pronounced for girls. The findings point to a complex interplay between family stress and functioning, dietary habits, and the HRQOL of children during the COVID-19 pandemic, particularly concerning girls' food intake and well-being.

Promoting public playgrounds usage and children's physical activity with sports activities: A quasi-experimental study

This study aimed to evaluate the children's usage and their physical activity levels at playgrounds with (N = 4) and without (N = 4) organized sports activities, following a quasi-experimental study design. Direct observations were used to assess the playground usage and estimate the playground users' age category, sex, and physical activity intensity level. The results indicated that playgrounds with sports activities were associated with 53% more users at the time of the activities. However, this increase was only seen in boys. Furthermore, playgrounds with sport activities were not associated with different physical activity levels in children as compared to children on regular playgrounds.

Is there an association between proficiency in fundamental movement skills and mderate-to-vigorous physical activity in childhood on weekdays and weekends? The REACT project.

The present study probes into the association between children's fundamental movement skills (FMS) and moderate-to-vigorous physical activity (MVPA) during weekdays and weekends. This cross-sectional sample included 1014 children aged 6-10 years from the REACT project. Physical activity was assessed with accelerometry, and five FMS (stationary dribble, kick, catch, overhand throw, and underhand roll) were assessed with the digital platform Meu Educativo®. Three groups were formed based on the frequency of FMS that each child mastered: group 1 (wizard level in four or five FMS); group 2 (wizard level in two or three FMS); and group 3 (wizard level in at most one skill). Multilevel models were used to analyze the data treating children (level-1) nested within schools (level-2). Compared to group 1, groups 2 (-12.9 ± 2.3 min day-1) and 3 (-23.9 ± 2.4 min day-1) were less physically active during weekdays and weekends (group 2: -14.7 ± 2.7 min day-1 and group 3: -22.4 ± 2.9 min day-1), independent of age and sex. There was a decline in MVPA during the weekend. Further, on average, boys were more active than girls, and with increasing age, children were less active. On average, children with higher FMS levels are generally more physically active than their peers with lower FMS levels. Even though MVPA tends to decline on weekends, FMS proficiency is a significant factor in maintaining 60 min of MVPA on weekends.

Association between Screen Time and Sociodemographic Factors, Physical Activity, and BMI among Children in Six European Countries (Feel4Diabetes): A Cross-Sectional Study.

Screen time among children in most European countries is notably high and is influenced by various sociodemographic and other factors. Our study aimed to explore the associations between parents' sociodemographic characteristics, socioeconomic status, body mass index (BMI), physical activity, risk status for type 2 diabetes, and their children's BMI, physical activity, and screen time. The data were sourced from the 2016 Feel4Diabetes study, involving 12,280 parents and 12,211 children aged 6-9 years (average age 8.21 years) in a cross-sectional study design. We used a logistic regression model to identify potential factors associated with children's screen time. The results showed that mothers with tertiary education (OR = 0.64; 95%CI = 0.49-0.82; p < 0.001), the middle age group (45-54 years) (OR = 0.81 95%CI = 0.66-0.98; p = 0.033), and families with higher incomes (middle-OR = 0.85; 95%CI = 0.75-0.97; p = 0.014; high-OR = 0.8; 95%CI = 0.69-0.93; p = 0.003) were associated with a decreased chance of children spending more than 2 h/day in front of the screen. In contrast, maternal overweight/obesity (OR = 1.15; 95%CI = 1.03-1.29; p = 0.013) and lower physical activity in children were linked to an increased likelihood of more than 2 h of screen time per day. Our findings suggest that targeted interventions should be developed to mitigate excessive screen time, particularly focusing on low-income families and mothers with low educational levels.

Parental Upbringing, Nutritional Status, and Physical Activity in Preschoolers

Introduction: In Mexico the prevalence of childhood obesity has experienced an alarming increase; it was reported that 9.7% of children under 5 years of age were suffering from overweight or obesity. This situation was exacerbated in the northern region of the country with a prevalence of 13.2%. Within this context, Parenting Style has been identified as a determinant factor in children's eating behavior, directly influencing their Body Mass Index. Aim: To understand the relationship between Parenting Styles (General and by type of Parenting Style), Body Mass Index, and Physical Activity of preschoolers. Methodology: A cross-sectional, descriptive, and correlational study involved 664 individuals, comprising 332 mother/child dyads, aged between 3 and 5 years. Variables were measured using the Parenting Styles and Dimensions Questionnaire (PSDQ) and the Physical Activity Questionnaire for Parents of Preschool Children, with descriptive and correlational statistics being conducted. Results: A positive and significant correlation was found between the Democratic Parenteral Parenting Style with the minutes that preschoolers dedicated to performing mild physical activities (rs = .136, p&lt;0.05) and moderate physical activities (rs = .172, p&lt;0.01). ). Permissive and authoritarian parenting styles did not show significant relationships with minutes of physical activity. Discussion: Despite the lack of correlation between the general Parenting Style and BMI, this finding underscores the complexity of factors shaping children's physical activity, suggesting the need for multifaceted strategies that include parental education, improvements in infrastructure, and public policies to promote a healthy lifestyle among children.

Caregiver perceptions of child heath behaviors and weight during treatment for acute lymphoblastic leukemia.

Changes in health behaviors and weight are common during the early phases of pediatric acute lymphoblastic leukemia treatment, and may negatively impact treatment tolerability.. Given that ALL is most prevalent in children, caregivers play an essential role in shaping health behaviors during treatment. This study presents a qualitative analysis of semi-structured interviews with caregivers of youth in the early phases of ALL treatment. Caregivers (N=17, 95% female) of a child (M age=6.76years) diagnosed with ALL and on treatment for less than 1year (M=8.7months since diagnosis) completed a semi-structured interview about perceptions of their child's nutrition, physical activity, sedentary time, and weight during ALL treatment. Thematic analysis followed Braun and Clark's six-step framework (2006). Two coders established reliability (alpha=.88) and used a multi-pass coding system to extract themes. Caregivers' concerns around their child's weight during ALL treatment primarily centered around avoiding malnutrition. Weight gain during treatment was less of a concern and often viewed as protective. Caregivers reported encouraging their child to eat palatable, calorie-dense foods to mitigate risk for weight loss. Caregivers also expressed concern that children were less active and more sedentary due to treatment-related pain. Caregivers discussed health behaviors during treatment as being child-directed, rather than parent- or provider-directed. Future interventions may consider strategies to engage in joint parent-child decisions and caregiver education around risks of excessive weight gain during treatment. Interventions should include anticipatory guidance and aim to support parents in developing skills to support their child's health behaviors during treatment.

A Longitudinal Examination of Direct and Indirect Influences of Parental Behaviors on Child Physical Activity

AbstractMany children do not realize the physical health, mental health, cognitive, and academic benefits of physical activity because they are insufficiently active. Effectively promoting physical activity in children requires understanding the determinants of physical activity. Parent physical activity and support for physical activity have emerged as central influences, but few studies have applied longitudinal designs and device-based measures of child physical activity. The purposes of this cohort study were to examine direct associations between parent physical activity and child physical activity, parent physical activity and parent support for physical activity, and parent support and child physical activity; and to examine indirect associations between parent physical activity and child physical activity, mediated through parent support behaviors. We used structural equation modeling with panel analysis to examine direct and indirect influences of parent physical activity and support on 7th grade children’s physical activity, adjusted for 5th grade levels. Parent surveys were administered at the 5th grade time-point. Parent physical activity indirectly affected child physical activity, mediated through the parent support behavior of providing transportation for physical activity. Parent physical activity was also directly related to four parent support behaviors. Increasing parent support for child physical activity, and possibly parent physical activity, may be effective approaches to increasing child physical activity.
