Physical Activity for Young Children: A Quantitative Study of Child Care Providers’ Knowledge, Attitudes, and Health Promotion Practices

Many preschool children fail to achieve the National Association for Sport and Physical Education physical activity recommendations placing themselves at increased risk of overweight and its associated health consequences. The early learning and care system is well positioned to intervene. Yet few child obesity prevention efforts have focused on systematically integrating physical activity into early learning and care. A pre/post design examined the association between changes in physical activity practices and providers’ beliefs regarding their role in supporting children’s physical activity. Survey and observational data from 43 sites participating in the Encouraging Healthy Activity and Nutrition in Child Care Environments pilot project were analyzed. Statistically significant increases were found in providers’ perceptions of role salience and the need for adult leadership to increase children’s physical activity. Significant improvements in indoor child care physical activity practices, physical education, and family communication occurred. A binary logistic regression indicated that changes in adult leadership and role salience were significantly associated with changes in physical activity practices. Understanding and modifying child care providers’ beliefs regarding their role in children’s physical activity is a critical component for the successful implementation of obesity prevention initiatives designed to increase child activity levels.

Peer Influence and Physical Activity Behavior in Young Children: An Experimental Study

There is evidence that the presence of a friend increases physical activity behavior in school-aged children (≥ 8 years old) and in young adolescents. Little is known about the developmental trajectory of the effects of peer influences on children's physical activity. Therefore, we sought to test the effect of the presence versus absence of a friend on physical activity in young children (≤ 6 years old). Physical activity was assessed, via accelerometery, in 3- to 6-year-old children, during 2 social conditions: alone and in the presence of a friend. During each condition, children were taken to a gymnasium and had free access to physical and sedentary activities for 30 minutes. In one condition children were tested alone (solo play), whereas in the other they were tested in the presence of a friend who had access to the same activities. Children exhibited 54% greater (P < .02) average accelerometer counts during the friend condition (mean = 2629, SD = 1080 or 5.7 METs) than during the solo play condition (mean = 1707, SD = 1009 or 4.5 METs). The presence of a friend contributes to increased physical activity behavior in young children.

Physical Activity and Blood Pressure in Primary School Children

High blood pressure (BP) is becoming increasingly common during childhood. Regular physical activity (PA) reduces BP in adults, but limited studies have reported inconsistent results among children. The aim of this study is to examine, for the first time, the cross-sectional and longitudinal associations between BP and objectively measured PA in young children of predominantly South Asian background. Data from the Birmingham healthy Eating and Active lifestyle for CHildren Study were analyzed. Five hundred seventy-four children, aged 5 to 7 years, underwent a series of measures at baseline and were followed up 2 years later. PA was objectively measured using accelerometry and converted to counts per minute (total PA, cpm), and time spent in moderate-vigorous PA (minutes per day). BP was measured by trained staff using standard protocols. Data were available for 512 children at baseline (mean age 6.5 years, range 5.4–7.8 years), and 427 of these children were followed up. Baseline total PA was inversely associated with diastolic BP at both baseline (adjusted regression coefficient: −0.75 mm Hg [95% CI −1.33 to −0.18] per 20 cpm) and follow-up (−0.74 mm Hg [95% CI −1.40 to −0.08]). All associations remained unchanged after further adjustment for weight status. This study strengthens evidence of a causal association between higher PA and lower BP in children as young as 5, independent of weight status. The results provide support for development of interventions to increase PA in young children.

Early childhood predictors of toddlers' physical activity: longitudinal findings from the Melbourne InFANT Program.

BackgroundYoung children are at risk of not meeting physical activity recommendations. Identifying factors from the first year of life which influence toddlers’ physical activity levels may help to develop targeted intervention strategies. The purpose of this study was to examine early childhood predictors of toddlers’ physical activity across the domains of maternal beliefs and behaviours, infant behaviours and the home environment.MethodsData from 206 toddlers (53% male) participating in the Melbourne InFANT Program were collected in 2008–2010 and analysed in 2012. Mothers completed a survey of physical activity predictors when their child was 4- (T1) and 9- months old (T2). Physical activity was assessed by ActiGraph GT1M accelerometers at 19- months (T3) of age.ResultsOne infant behaviour at T1 and one maternal belief and two infant behaviours at T2 showed associations with physical activity at T3 and were included in multivariate analyses. After adjusting for the age at which the child started walking and maternal education, the time spent with babies of a similar age at 4-months (β = 0.06, 95% CI [0.02, 0.10]) and the time spent being physically active with their mother at 9-months (β = 0.06, 95% CI [0.01, 0.12]) predicted children’s physical activity at 19-months of age.ConclusionsPromotion of peer-interactions and maternal-child co-participation in physical activity could serve as a health promotion strategy to increase physical activity in young children. Future research is required to identify other early life predictors not assessed in this study and to examine whether these factors predict physical activity in later life stages.

Comparison of Measures of Physical Performance Among Young Children Who Are Healthy Weight, Overweight, or Obese

To determine the differences in gait, balance, muscle strength, and physical activity in young children who are healthy weight (HW), overweight (OW), or obese. Participants (n = 70; 5-9 years) were classified according to their body mass index as OW/obese (n = 29) or HW (n = 41). Data were collected on gait parameters, 1-leg stance test (OLST), handgrip strength, vertical jump (VJ) height, and physical activity. An independent t test, Mann-Whitney U test, analysis of covariance (ANCOVA), and regression analyses were carried out. Being OW/obese resulted in a significantly increased base of support while walking (P < .05), decreased OLST performance (P < .05), and decreased VJ height (P < .01) compared with peers of HW. These findings suggest that in young children, being OW/obese may lead to an increased base of support while walking, decreased balance, and decreased leg explosive strength.

Comparison of activity levels measured by a wrist worn accelerometer and direct observation in young children

Introduction: Motion sensors are mechanical and electronic devices, which detect the body movement and provide an estimate of physical activity in children and adults. However, they need to be validated against criterion methods such as direct observation. The purpose of this study was to validate a wrist worn accelerometer to quantify the physical activity of children, by comparison to direct observation using the Children’s Activity Rating Scale (CARS). Materials and Methods: Data were recorded from 42 children, aged 3 - 5 years (22 boys and 20 girls), of whom each was observed each minute for 2 hours using Children’s Activity Rating Scale (CARS) while they wore the Actiwatch. Results: The CARS score and activity counts from the accelerometer were averaged over 1- to 10-minute periods across all individuals. There was a significant positive correlation between the mean CARS scores and the mean Actiwatch counts over simultaneous 1- to 10-minute periods ranging from r = 0.41 to r = 0.63 (P tween the predicted and the observed CARS scores in the validation sample. Given the data from the Actiwatch (averaged over a 5-minute epoch), the equivalent CARS score could be calculated with a 95% confidence level of plus or minus 0.74 CARS units. Conclusion: These data suggest that the Actiwatch (a wrist worn accelerometer) is a valid tool for assessing levels of physical activity in young children.

Association Between Hypothesized Parental Influences and Preschool Children's Physical Activity Behavior

Background: To date, most research investigating the influence of parents on children's physical activity behavior has been conducted among school-aged children. As a result, we have a limited understanding of the mechanisms through which parents can influence their young children's physical activity behavior. The purpose of this study was to examine the influence of various hypothesized parental influence variables on children's physical activity behaviors. Methods: An on-line survey assessing various hypothesized parental influences and an estimate of the amount of time their child engaged in physical activity behavior was completed by 176 parents. Results: Parents who perceived physical activity to be important for their child, had confidence in providing support for their child's physical activity, had good physical activity experiences as a child, and had high perceptions of their child's physical ability were more likely to employ activity-facilitating parenting practices and behaviors that were associated with their preschool children's physical activity behaviors. Discussion and Translation to Health Education Practice: Parenting practices and behaviors (e.g., parental support for children's activity behaviors) may play an important role in preschool children's physical activity behaviors. Future prospective studies are needed to confirm the findings of the present study.

Impact of the REFRESH randomised controlled trial on the physical activity behaviours of mothers with young children

Introduction: Lifestyle factors relating to unhealthy diets and lack of physical activity have been implicated in excessive weight gain during pregnancy, interpregnancy weight gain, weight retention 12 months postpartum and long-term weight retention among women. Physical inactivity and unhealthy diets are among the modifiable risk factors that are associated with the major chronic diseases and are the risk factors which explain the vast majority of chronic disease deaths in the world. The aim of this abstract is to demonstrate the impact of REminder for Food Relaxation Exercise and Support for Health (REFRESH), a community based randomised controlled trial on mothers with young children's physical activity behaviours.

Multidimensional correlates of preschool children's physical activity*

Introduction: Physical activity is important for young children's health yet compliance with recommendations is low. Identifying factors associated with young children's physical activity is necessary to inform development of future interventions and public health programs. This study sought to identify multidimensional correlates of preschool children's physical activity.

Parent awareness of young children's physical activity

ObjectiveParents who overestimate their child's physical activity (PA) level may not encourage their children to increase their PA. We assessed parental awareness of child PA, and investigated potential correlates of overestimation. MethodChild PA (accelerometer) and parent-classified child PA [‘active’ ≥60min/day vs. ‘inactive’ <60min/day moderate and vigorous PA (MVPA)] were measured over 7days [n=329, 44% male, 39% Latino; mean (SD) 9.1 (0.7)years] in an obesity prevention study in San Diego (Project MOVE). Agreement between date-matched objective MVPA and parent-classified child PA was assessed; % days parental overestimation was the outcome variable. Associations between parental overestimation and potential correlates were investigated using three-level mixed‐effects linear regression. ResultsChildren met the PA guidelines on 43% of days. Parents overestimated their children's PA on 75% of days when children were inactive. Most parents (80%) overestimated their child's PA on ≥1 measurement day. Parental support for child PA (transport, encouragement and participation with child) (p<0.01) was positively associated with higher overestimation. Parents of girls showed more overestimation than parents of boys (p=0.04). ConclusionMost parents incorrectly classified their child as active when their child was inactive. Strategies addressing parental overestimation may be important in PA promotion.

Weight status and gender-related differences in motor skills and in child care - based physical activity in young children

BackgroundOver the last decades, a decline in motor skills and in physical activity and an increase in obesity has been observed in children. However, there is a lack of data in young children. We tested if differences in motor skills and in physical activity according to weight or gender were already present in 2- to 4-year-old children.MethodsFifty-eight child care centers in the French part of Switzerland were randomly selected for the Youp'là bouge study. Motor skills were assessed by an obstacle course including 5 motor skills, derived from the Zurich Neuromotor Assessment test. Physical activity was measured with accelerometers (GT1M, Actigraph, Florida, USA) using age-adapted cut-offs. Weight status was assessed using the International Obesity Task Force criteria (healthy weight vs overweight) for body mass index (BMI).ResultsOf the 529 children (49% girls, 3.4 ± 0.6 years, BMI 16.2 ± 1.2 kg/m2), 13% were overweight. There were no significant weight status-related differences in the single skills of the obstacle course, but there was a trend (p = 0.059) for a lower performance of overweight children in the overall motor skills score. No significant weight status-related differences in child care-based physical activity were observed. No gender-related differences were found in the overall motor skills score, but boys performed better than girls in 2 of the 5 motor skills (p ≤ 0.04). Total physical activity as well as time spent in moderate-vigorous and in vigorous activity during child care were 12-25% higher and sedentary activity 5% lower in boys compared to girls (all p < 0.01).ConclusionsAt this early age, there were no significant weight status- or gender-related differences in global motor skills. However, in accordance to data in older children, child care-based physical activity was higher in boys compared to girls. These results are important to consider when establishing physical activity recommendations or targeting health promotion interventions in young children.

Daily physical activity in young children and their parents: A descriptive study.

Little is known about physical activity (PA) in young children and about the relationship between their PA and that of their parents. The main purpose of the present study (Y-Be-Active) was to examine the daily PA levels of young children and their parents, and to explore the relationship between children's and parents' PA. Fifty-four children (mean age 4.3 years) and their parents (54 mothers, mean age 35.8 years; 50 fathers, mean age 38.2 years) wore accelerometers for three weekdays and two weekend days. Parents also completed questionnaires on family sociodemographics and PA habits. Children spent most of their time in light PA. Almost all children attained 30 min of daily moderate-to-vigorous PA (MVPA), and most boys and girls attained 60 min of daily MVPA on weekdays. Only 60% of fathers and approximately one-half of mothers attained 30 min of daily MVPA on weekdays and weekend days. Children's and fathers' PA were correlated on weekends. Few parents (20% to 30%) participated regularly in organised PA with their child. Fathers' involvement in PA with their children was associated with higher MVPA in children. Many young children and parents did not meet current Canadian recommendations for daily PA. Parental involvement in PA with their young children, particularly the involvement of fathers, appeared to promote higher levels of MVPA in young children.

Existing policies, regulation, legislation and ongoing health promotion activities related to physical activity and nutrition in pre‐primary education settings: an overview

Obesity prevention efforts for school-aged children and adolescents are increasing in number. However, little has been done to address the problem in the preschool age. To address this age group, an evidence-based preschool programme on physical activity (PA) and nutrition is developed within the ToyBox project. Environmental influencing factors such as policies and competitive health promotion activities could inhibit or induce a successful health promotion programme. This paper describes an overview of existing policies, legislation and/or regulations and health promotion activities in the preschool setting. data were gathered on policies and activities aiming to improve healthy eating and PA of young children (age group 4-6 years) in Belgium-Flanders, Bulgaria, Germany, Greece, Poland and Spain. A limited number of influencing policies, regulations and/or legislation exists; agenda setting of health promotion and policy evaluations in all relevant policy areas was lacking. Also, health promotion activities in preschool the setting did not exist in all six European countries and high-quality preschool-based health interventions existed in three of the six ToyBox countries.

Physical activity guidelines for preschoolers: a call for research to inform public health policy

There are many challenges in developing evidence-based physical activity guidelines for preschoolers that can ensure health benefits for children. Guidelines for the preschool years have recently been developed in several countries, but there are notable inconsistencies in the amount of physical activity regarded as sufficient for this age group. Given the currently high prevalence of childhood obesity, there is an urgent need for evidence-based studies to inform the development of community-targeted programs to ensure healthy levels of physical activity in young children. Our article outlines the global recommendations for physical activity for children ≤ 5years of age. We identify gaps in the literature and suggest recommendations for future research and public health policy.

The Relationship Between Motor Proficiency and Pedometer-Determined Physical Activity in Young Children

The aim of this study was to examine the relationship between motor proficiency and pedometer-determined physical activity in 5-6 year-old children. Participants (n = 232) were randomly recruited and assessed from 30 kindergartens in Northern Greece. Two trained researchers administered the measurements for the assessment of children's motor proficiency by using the BOTMP-SF. Physical activity was assessed by OMRON pedometers. Significant relationships between BOTMP-SF standard score and steps (S), aerobic walking time (AWT) and aerobic steps (AS), (p < .05) were found. When motor proficiency was divided into quartiles to assess the distribution of the relationship between motor proficiency and pedometer-derived variables, significant associations were found for AWT, S and AS (p < .001). Young children with high levels of motor proficiency were more active in contrast to their peers with lower motor proficiency. The findings add to the growing body of literature that considers motor skills/abilities as important elements of physical activity participation. ( S-steps per day; AS-aerobic steps per day; AWT-aerobic walking time (minutes·day(-1)); BOTMP-SF-Bruininks-Oseretsky Test of Motor Proficiency-Short Form (standard score)).

Development of the Early Activity Scale for Endurance for Children With Cerebral Palsy

The Early Activity Scale for Endurance (EASE) was developed as a clinically feasible measure of endurance for physical activity in young children with cerebral palsy (CP). Validity and reliability were evaluated. Participants included 414 children with CP and 106 without CP. Parents completed the EASE, an 11-item self-report measure. For construct validity, EASE scores were compared by Gross Motor Function Classification System levels (0 assigned for children without CP), age, and gender. In subgroups, convergent validity with the 6-minute walk test and test-retest reliability with a second EASE were evaluated. EASE scores differed significantly by Gross Motor Function Classification System, but not by age or gender. The EASE correlated moderately (rs = 0.57) with the 6-minute walk test. Test-retest reliability was high, intraclass correlation (2,1) = 0.95. The EASE has acceptable psychometrics for use in practice and research to estimate endurance for physical activity in young children with CP.

Physical activity in young children: a systematic review of parental influences

The primary aim of this review was to identify and evaluate the strength of associations of the key parental factors measured in studies examining early childhood physical activity (PA). A systematic review of the literature, using databases PsychINFO, Medline, Academic Search Complete, PSYCHinfo, and CINHAL, published between January 1986 and March 2011 was conducted; 20 papers were relevant for the current review. While 12 parenting variables were identified, only 5 of these had been investigated sufficiently to provide conclusive findings. There were inconsistencies in the findings involving the social learning variable parental enjoyment and variables involving parental behaviours such as maternal depression and self-efficacy, and rules for sedentary behaviour, and parental perceptions, which included perceived importance of PA, fear of safety, and perception of child's motor competence. Given these inconsistencies, a meta-analysis was conducted to determine whether the method of measuring PA (objective or subjective) influenced the strength of associations between the parental factors and young children's PA. There was no difference in the strength of associations in the studies that used objective or subjective measurement (via parent self-report). Further investigation is needed to clarify and understand the specific parental influences and behaviours that are associated with PA in young children. In particular, longitudinal research is needed to better understand how parental influences and PA levels of children during the formative preschool and early elementary school years are associated.

Objective Measurement of Habitual Sedentary Behavior in Pre-School Children: Comparison of Activpal With Actigraph Monitors

The Actigraph is well established for measurement of both physical activity and sedentary behavior in children. The activPAL is being used increasingly in children, though with no published evidence on its use in free-living children to date. The present study compared the two monitors in preschool children. Children (n 23) wore both monitors simultaneously during waking hours for 5.6d and 10h/d. Daily mean percentage of time sedentary (nontranslocation of the trunk) was 74.6 (SD 6.8) for the Actigraph and 78.9 (SD 4.3) for activPAL. Daily mean percentage of time physically active (light intensity physical activity plus MVPA) was 25.4 (SD 6.8) for the Actigraph and 21.1 (SD 4.3) for the activPAL. Bland-Altman tests and paired t tests suggested small but statistically significant differences between the two monitors. Actigraph and activPAL estimates of sedentary behavior and physical activity in young children are similar at a group level.

Using interviews and peer pairs to better understand how school environments affect young children's playground physical activity levels: a qualitative study

School break times provide a daily opportunity for children to be active; however, research indicates this time is underutilized. Reasons for low children's playground activity levels have primarily focused on physical barriers. This research aimed to contribute to physical environmental findings affecting children's playground physical activity levels by identifying additional variables through the interview process. Thirteen public schools were included in the sample (total 2946 children). Physical activity and environmental data were collected over 3 days. Environmental variables were manually assessed at each of the 13 schools. Observational data were used to determine which three schools were the most and least active. The principal, three teachers and 20 students in Grades 4-6 from these six schools (four lower and two average socioeconomic status) were invited to participate in the interview process. Student interviews involved the paired interview technique. The main themes generated from the school interviews included the effect of non-fixed equipment (including balls), playground markings, playground aesthetics, activity preference, clothing, the amount of break time available for play, teacher playground involvement, gender, bullying, school policies, student confidence in break-time activity and fundamental movement skills. The effect of bullying on playground physical activity levels was concerning.
