Physical activity, sports participation and exercise-related constraints in adult women with primary hypothyroidism treated with thyroid hormone replacement therapy.

Awareness of physical activity (PA) constraints in patients with primary hypothyroidism on thyroid hormone replacement therapy (THR) is important. Hence, this cross-sectional matched case-control study aimed to determine PA and sports participation (SP) in patients with hypothyroidism on THR in comparison to control subjects. Accordingly, survey questions were selected from the National Survey on Injuries and Physical Activity in the Netherlands (IPAN), supplemented with questions related to self-reported clinical characteristics and exercise-related constraints (ERC) of patients. In total, 1,724 female patients (mean age 53.0 years ±11.6) and 1,802 controls (mean age 52.6 ± 13.2) were included. Compared to controls, patients were less likely to comply with the moderate-intensity PA guideline (OR 0.70; 95% CI: 0.611-0.803), although patients were more actively participating in sports (OR 1.40; 95% CI: 1.156-1.706). Two-thirds of patients reported that hypothyroidism was limiting their PA performance. These limitations were more pronounced in patients with autoimmune thyroiditis (AIT) than in patients with hypothyroidism from other aetiology (OR 1.93; 95% CI: 1.518-2.457), representing disease-specific exercise intolerance. In order to establish effective intervention programmes to encourage regular PA in hypothyroid patients on THR with exercise intolerance, further research is warranted to better understand PA barriers.

The training and support needs of 22 programme directors of community-based childhood obesity interventions based on the EPODE approach: an online survey across programmes in 18 countries.

BACKGROUND: Tackling childhood obesity is complex and requires a community-based approach implemented in multiple environments. It is known from literature that knowledgeable and skilled professionals are essential to implement such an approach successfully. The aim of the present study was to assess the need for training and support among a global network of programme directors implementing a Community-Based Childhood Obesity Intervention (CBCOI) based on the EPODE approach, in order to assist them in optimising the implementation process. METHODS: An online survey was sent to 40 programme directors representing programmes implementing a CBCOI based on the EPODE approach. The survey consisted of statements on a 5-point Likert scale and multiple-choice questions about attitude towards and usefulness of training and support, and preferences for some predefined training types and training topics. In total, 22 programme directors responded to the survey (55% response rate). Data were analysed using descriptive statistics to describe the need for support in order to improve successful implementation. RESULTS: Respondents strongly agreed that continually updating skills and learning how to make their programmes more effective and sustainable at the start and during the implementation was important. On-site training was preferred most at the commencement of a programme, while a 2-day training course was most valued during implementation. Monitoring, measuring and programme evaluation was identified as the most valuable training topic. CONCLUSIONS: The results indicate a continuing and significant need for support and training among programme directors implementing a CBCOI. The findings give directions regarding topics and types of training and support in order to improve the implementation process.

Economic burden of physical activity-related injuries in Dutch children aged 10-12.

BACKGROUND: Injuries in children occur most often in physical activity-related activities. A lot of these injuries result in direct and indirect costs. A detailed overview of the economic burden of those injuries in children is lacking. METHOD: A prospective study was conducted with 996 children in Dutch primary schools to describe the economic burden of injuries that occur during organised sports, leisure time and physical education (PE) class activities. Injuries were continuously monitored by PE teachers during the school year 2006-2007. An injury was recorded if it occurred during PE class, leisure time or organised sports activity and caused the child to at least stop the current activity. If an injury was recorded, parents received a cost diary to report the direct and indirect costs of the child's injury. Costs were collected from a societal perspective. RESULTS: During one school year, a total of 119 injuries were reported by 104 children. The mean total costs as a result of an injury were €188 ± 317. The mean direct costs as a result of an injury were much higher than the mean indirect costs (€131 ± 213 and €57 ± 159, respectively). The highest costs were found for upper extremity and leisure time injuries. CONCLUSION: Physical activity-related injuries are common in children and result in medical costs. Injuries that lead to the highest costs are those that occur during leisure time activities and upper extremity injuries. Intervention programmes for children to prevent upper extremity injuries and leisure time activity injuries may reduce direct (ie, healthcare) and indirect costs. TRIAL REGISTRATION: ISRCTN78846684.

Process evaluation of a school based physical activity related injury prevention programme using the RE-AIM framework.

BACKGROUND: In general, only information regarding the effectiveness of an intervention programme is ever published. However, in recent years evaluating the translatability and feasibility of an intervention programme has become more important. Therefore, this paper presents the results of the evaluation of the iPlay programme aimed at preventing physical activity related injuries in primary school children. METHODS: The iPlay programme targeted injuries gained through physical activity, and consisted of a teacher's manual, informative newsletters and posters, a website, and set exercises to be carried out during physical education (PE) classes. In order to evaluate the iPlay programme for translatability and feasibility, teachers, children and parents who participated in the iPlay programme filled out a questionnaire. The objective of this study is to describe the results of the process-evaluation of the iPlay programme based on the five dimensions of the RE-AIM framework. RESULTS: The results showed that the participation rate of the children was 100% (reach). Nine percent of the schools who were invited to take part were willing to participate in the study (adoption rate). Teachers stated that they implemented the different elements of the programme partly as intended (implementation). The percentage of children and parents who followed the programme was less than expected. In addition, 52% of the teachers indicated that the current iPlay programme could become standard practice in their teaching routine (maintenance). CONCLUSION: The iPlay programme is a first start in the prevention of physical activity related injuries in children, but further improvements need to be made to the programme on the basis of this process evaluation.

Trends in Neuromotor Fitness in 10-to-12-Year-Old Dutch Children: A Comparison Between 2006 and 2015/2017.

Children with a low level of neuromotor fitness are less skilled to participate in sports activities. Moreover, lower levels of neuromotor fitness are related to adiposity, lower cardiovascular health, and poor self-esteem in children. The aim of this paper was to determine neuromotor fitness in 10-12-year-old Dutch children over a 10-year period. Test scores measured in 2015/2017 (N = 533 in 2015, N = 941 in 2017) were compared with scores of same-aged children measured in 2006 (N = 1986). Neuromotor fitness was assessed using the MOPER fitness test battery, including speed and agility, strength, flexibility, and coordination and upper-limb speed. Data were analyzed using multilevel linear regression models and tobit regression analyses in case of skewed distributions with an excess of zeros. Analyses were stratified by age and gender, and adjusted for level of urbanization. Children in 2015/2017 performed significantly worse on speed and agility (ß = 0.8 to 1.1 s), significantly better on coordination/upper-limb speed (ß = -1.0 to -0.6 s), and-except for 12-year-old girls-significantly worse on flexibility vs. children in 2006 (ß = -3.4 to -1.8 cm). Additionally, upper-body strength was significantly worse among 10-year olds (ß = -3.2 to -2.5 s) while leg strength was significantly worse among 11-year-olds in 2015/2017 vs. 2006 (ß = -1.8 to -1.7 cm). Trunk strength was worse among 11- and 12-year old boys (ß = 1.1 to 1.2 s). In line with a previously observed downward trend in neuromotor fitness among children (1980-2006), we found worse scores on speed and agility, and flexibility in 2015/2017 vs. 2006, stressing the need for interventions aimed at improving neuromotor fitness in order to promote physical activity and future health.

Design of the iPlay study: systematic development of a physical activity injury prevention programme for primary school children.

Health benefits of physical activity in children are well known. However, a drawback is the risk of physical activity-related injuries. Children are at particular risk for these injuries, because of a high level of exposure. Because of the high prevalence of physical activity injuries and the negative short- and long-term consequences, prevention of these injuries in children is important. This article describes how we systematically developed a school-based physical activity injury prevention programme using the intervention mapping (IM) protocol. IM describes a process for developing theory- and evidence-based health promotion programmes. The development can be described in six steps: (i) perform a needs assessment; (ii) identify programme and performance objectives; (iii) select methods and strategies; (iv) develop programme; (v) adopt and implement; and (vi) evaluate. First, the results of the needs assessment showed the injury problem in children and the different risk factors for physical activity injuries. Based on the results of the needs assessment the main focus of the injury prevention programme was described. Second, the overall programme objective of the injury prevention programme was defined as reducing the incidence of lower extremity physical activity injuries. Third, theoretical methods and practical strategies were selected to accomplish a decrease in injury incidence. The theoretical methods used were active learning, providing cues and scenario-based risk information, and active processing of information. The practical strategy of the injury prevention programme was an 8-month course about injury prevention to be used in physical education classes in primary schools. Fourth, programme materials that were used in the injury prevention programme were developed, including newsletters for children and parents, posters, exercises to improve motor fitness, and an information website. Fifth, an implementation plan was designed in order to ensure that the prevention programme would be implemented, adopted and sustained over time. Finally, an evaluation plan was designed. The injury prevention programme is being evaluated in a cluster randomized controlled trial with more than 2200 children from 40 primary schools throughout the Netherlands. The IM process is a useful process for developing an injury prevention programme. Based on the steps of the IM we developed an 8-month injury prevention programme to be used in physical education classes of primary schools.

Effectiveness of a school-based physical activity injury prevention program: a cluster randomized controlled trial.

OBJECTIVE: To study the effects of a school-based injury prevention program on physical activity injury incidence and severity. DESIGN: Cluster randomized controlled trial performed from January 1, 2006, through July 31, 2007. SETTING: Forty Dutch primary schools. PARTICIPANTS: A total of 2210 children (aged 10-12 years). INTERVENTION: Schools were randomized to receive either the regular curriculum or an intervention program that targeted physical activity injuries. OUTCOME MEASURES: Incidence and severity of physical activity injuries per 1000 hours of physical activity participation. RESULTS: A total of 100 injuries in the intervention group and 104 injuries in the control group were registered. Nonresponse at baseline or follow-up was minimal (8.7%). The Cox regression analyses adjusted for clustering showed a small nonsignificant intervention effect on total (HR, 0.81; 95% confidence interval [CI], 0.41-1.59), sports club (0.69; 0.28-1.68), and leisure time injuries (0.75; 0.36-1.55). However, physical activity appeared to be an effect modifier. In those who were less physically active, the intervention had a larger effect. The intervention reduced the total and leisure time injury incidence (HR, 0.47; 95% CI, 0.21-1.06; and 0.43; 0.16-1.14; respectively). Sports club injury incidence was significantly reduced (HR, 0.23; 95% CI, 0.07-0.75). CONCLUSION: We found a substantial and relevant reduction in physical activity injuries, especially in children in the low active group, because of the intervention. This school-based injury prevention program is promising, but future large-scale research is needed.

Acute physical activity and sports injuries in children.

An increase in the physical activity of individuals has many health benefits, but a drawback of an increase in physical activity is the risk of related injuries. To reduce the short- and long-term effects in terms of social and economic consequences, prevention of physical activity injuries is an important challenge. A sequence of prevention model has been proposed that aims to prevent physical activity injuries in different steps. The model includes (i) identification of the problem in terms of incidence and severity of physical activity injuries, (ii) identification of the risk factors and injury mechanisms that play a role in the occurrence of physical activity injuries, (iii) introduction of measures that are likely to reduce the future risk and (or) severity of physical activity injuries, and (iv) evaluation of the effectiveness of the measures by conducting a randomized controlled trial (RCT). This review describes what is currently known about all of the various aspects of the sequence of prevention in children (steps i-iv).
