This study examined the influence of gender and region on object control (OC) and locomotor skill development. Participants were 275 midwestern African American and 194 southwestern Hispanic preschool children who were disadvantaged. All were evaluated on the Test of Gross Motor Development-2 (Ulrich, 2000). Two, 2 Gender (girls, boys) x 2 Region (midwest, southwest) analyses of variance were conducted on OC and locomotor percentile rank. Both midwestern and southwestern preschoolers were developmentally delayed in locomotor and OC skills (< 30th percentile). There was a significant difference for gender (p < .0001) and Gender x Region interaction (p = .02) for OC skills. Boys outperformed girls in the midwestern and southwestern regions. For locomotor skills, there was a significant difference for region (p < .001), with midwestern preschoolers having better locomotor skills.

The number of obese children in the US remains high, which is problematic due to the mental, physical, and academic effects of obesity on child health. Data indicate that school-age children, particularly underserved children, experience unhealthy gains in BMI at a rate nearly twice as fast during the summer months. Few efforts have been directed at implementing evidence-based programming to prevent excess weight gain during the summer recess. Camp NERF is an 8-week, multi-component (nutrition, physical activity, and mental health), theory-based program for underserved school-age children in grades Kindergarten - 5th coupled with the USDA Summer Food Service Program. Twelve eligible elementary school sites will be randomized to one of the three programming groups: 1) Active Control (non-nutrition, physical activity, or mental health); 2) Standard Care (nutrition and physical activity); or 3) Enhanced Care (nutrition, physical activity, and mental health) programming. Anthropometric, behavioral, and psychosocial data will be collected from child-caregiver dyads pre- and post-intervention. Site-specific characteristics and process evaluation measures will also be collected. This is the first, evidence-based intervention to address the issue of weight gain during the summer months among underserved, school-aged children. Results from this study will provide researchers, practitioners, and public health professionals with insight on evidence-based programming to aid in childhood obesity prevention during this particular window of risk.

Early childhood is a crucial time for children to develop their fundamental motor skills (FMS), serving as a foundation for engagement in lifelong physical activity (PA). With increasing concerns over the declining levels of PA and motor competence (MC), the aim of this study was to explore the predictors of PA in children in a play-based curriculum. A secondary purpose was to explore levels of PA and MC during the school day. The final aim was to explore whether there were sex differences. Children (N = 94; Mage = 68.96 months, SD = 8.25) in five classes from four different schools in Wales were tested on the TGMD-2, standing long jump, and MABC-2. Levels of PA were measured using ActiGraph GT3X-BT accelerometers, and 85 children met the wear time criteria. Object control (OC) skills, standing long jump, and age significantly predicted the percentage of time spent performing sedentary behaviours F(10,73) = 3.026, p = 0.003, $R^2$ = 0.29 (adj $R^2$ = 0.20) and time spent on MVPA F(10,73) = 3.597, p < 0.001, $R^2$ = 0.33 (adj $R^2$ = 0.24). Children spent an average of 48.7% of the school day performing sedentary behaviours and 9.1% performing moderate to vigorous physical activity (MVPA) and did not achieve 60 min of MVPA. The MABC revealed that 67% were below the 15th percentile. Girls spent more time than boys performing sedentary behaviours (p = 0.014), and boys spent more time than girls on MVPA (p = 0.004). Boys outperformed girls at OC skills (p < 0.001), while girls outperformed boys at locomotor skills (p < 0.001). These findings reinforce the pivotal role teachers and parents play in providing opportunities for children to be PA. OC skills and jump were positively associated with PA, emphasising the importance of developing FMS in early childhood. There were also sex disparities for both PA and MC, along with low levels of MC, highlighting the need for investing in comprehensive programmes and initiatives that prioritise the development of FMS during early childhood.

The MiniMovers (MM) APP combines motor development theory with creativity expertise and has been designed to provide parents with developmentally appropriate activities to support children’s motor skills. This study investigates how MiniMovers activities enabled parents to support their children’s physical development. Families participated in an 8-week MM programme of activities from the MM APP (Mini, Mighty and Mega levels), with pre- and post-intervention data collected using multiple tools (e.g., motion capture system, force plate, eye-tracking glasses, and videos). Mixed research methods were applied among children (N = 8; aged 21–79 months) and their parents, providing quantitative analysis on children’s performance (running, throwing, jumping, kicking, balancing and catching), as well as qualitative analysis on parents’ attitude and behaviour (two-weekly feedback surveys and interviews). Lab-based measures showed significant improvements in run time, underarm throwing distance, and horizontal jump distance. Test of Gross Motor Development-3 showed a significant gain in running, underarm and overarm throwing, horizontal jump and kicking. Further, developmental stages indicated significant improvements in running, kicking and catching. Parents reported increased enjoyment and knowledge, children’s enjoyment, independence and confidence. This pilot study provides support for the research and development of the MM App and suggests more research into the use of APPs to support home activities among families with young children.

The most efficacious childhood obesity prevention interventions have involved caregivers directly or indirectly. Due to the high reliance on technology, research examining technological intervention approaches is warranted, particularly during the summer when parents may be more difficult to engage and the risk for excess weight gain among children is high. The feasibility and acceptability of a multi-component childhood obesity prevention intervention incorporating a caregiver component utilizing technology-based approaches—texting and social media—was explored. This was an internal pilot of the Camp Nutrition Education Recreation and Fitness (NERF) study, a group RCT for school-age children coupled to the USDA Summer Food Service Program. Feasibility and acceptability of the technology caregiver engagement component were assessed via process outcomes (participation rates) and in-depth interviews. Participants (n = 37) were 91.9% female, 91.8% Black, 58.7% low-income, and 75.0% overweight/obese. Participation rates in texting and social media were 62.2% and < 3%, respectively. Themes emerged from the in-depth interviews were texting provides connection; desire more involvement with program; fear social media privacy intrusion. Results will be used to inform changes to technology-based caregiver engagement strategies to be tested in future interventions. Clinical Trials, NCT02908230 /09-19-2016. Registered 20 September 2016
