Physical activity and motor skill outcomes of a 10-week intervention for children with intellectual and developmental disabilities ages 4–13: A pilot study

BackgroundChildren with intellectual and developmental disabilities (IDD) often experience increased barriers to engaging in physical activity (PA) which can stem from lack of gross motor function (GMF) development. Intervening on GMF at an early age can create better opportunities for children with IDD to engage in regular PA. In turn, increased PA can improve health outcomes and increase social skills.ObjectiveThe primary objective of this pilot study was to explore the effectiveness of a community-based GMF-focused PA intervention for improving overall motor skills and PA for children with IDD.MethodsAll study participants (n = 24) engaged in 10 weeks of programming for 1 h each week. A convenience sample was utilized.ResultsResults indicated no statistically significant changes pre to post for motor skill scores. However, a visual analysis of mean changes showed a consistent pattern of increased scores from pre to post on most skills. Additionally, we found that a change in participant locomotor skills significantly predicted change in Moderate to Vigorous Physical Activity (MVPA), F (1,11) = 5.16, Adj R² = .26, p = .04.ConclusionsThese results suggest individualized attention on GMF may help to increase motor skills for children with IDD. This study adds to the small but growing amount of research examining the efficacy of community based adapted PA interventions. Further, study results should support continued exploration of effective approaches to address the motor delays experienced by children with IDD.     

Mental health and socioeconomic status impact adherence to youth activity and dietary programs: a meta-analysis

PurposeSubstantial efforts have gone into reducing the physiological and psychological harm of obesity in youth, but few studies have reviewed the factors contributing to adherence to pediatric weight management programs. The attrition rates to programs offering multiple components to address BMI improvement and healthy lifestyle change among youth are quite high. The purpose of this study is to review the literature for factors contributing to adherence to these programs among children and youth with obesity and determine pooled effect of these factors.MethodsA systematic literature search and meta-analysis was conducted through the PubMed database on pediatric weight management interventions offering at least physical activity and dietary support for obese youth aged 10–17 years, where variables contributing to adherence were reported. Only those studies achieving a threshold of methodological rigour were included.ResultsAltogether, seven studies were included in the analysis. There was a pooled RR of lower socioeconomic status on non-adherence of 1.34 [95% confidence intervals 1.19–1.52] and poorer mental health on non-adherence of 1.12 [95% confidence intervals 1.08–1.17].ConclusionIt is important to address barriers related to lower socioeconomic status in pediatric weight management programs to increase adherence. Further, addressing supports for those with poorer mental health can reduce the risk of non-adherence in multi-disciplinary programs targeting youth with obesity.     

渐进式心脏运动康复护理对冠心病经皮冠状动脉介入术后患者心功能的影响

目的探讨冠心病经皮冠状动脉介入术(PCI)治疗患者,在术后早期进行渐进式心脏运动康复护理干预对患者心功能的影响。方法选择2017-2018年营口市中心医院收治的冠心病并行PCI患者120例,随机分为对照组和干预组各60例。对照组进行常规护理,干预组在对照组基础上在术后进行6个月的渐进式心脏运动康复护理干预,对比干预后两组心功能改善情况。结果两组干预后射血分数(LVEF)均提高,干预前后组内及干预后组间比较差异均有统计学意义(P<0.05)。两组术前LVEF<50%者,干预后LVEF均增加,组内干预前后LVEF相比差异有统计学意义(PC0.05),组间干预后LVEF相比差异无统计学意义(P>0.05)。两组术前LVEF为50%?60%者,组内干预前后及组间干预后LVEF差异均有统计学意义(P<0.05)。两组术前LVEF>60%者,干预前后组内和组间LVEF相比,差异均无统计学意义(P>0.05)。结论渐进式心脏运动康复护理干预能够改善冠心病行PCI治疗患者术后的心脏泵血能力,但是这种效果受患者术前LVEF水平的影响。
