Co-design and content validity of the movement measurement in the early years (MoveMEY) tool for assessing movement behaviour of pre-school aged children

Abstract Background Movement behaviours (physical activity, sedentary behaviour, and sleep) are important for pre-school children’s health and development. Currently, no tools with appropriate content validity exist that concurrently capture these movement behaviours in young children. The aim of this study was to co-design and assess the content validity of a novel tool to concurrently measure movement behaviours in pre-school aged children (aged 3–4 years). Methods We followed four distinct steps to develop and assess the content validity of Movement Measurement in the Early Years (MoveMEY): (1) We conducted an extensive literature search, to identify pre-existing proxy measurement tools (questionnaires and diaries) to inform the design of a novel tool, which aimed to effectively capture movement behaviour guidelines of pre-school aged children. (2) We facilitated focus group discussions with parents and carers of pre-school aged children (n = 11) and (3) a qualitative survey with free text responses was completed by topic relevant researchers (n = 6), to co-design the measurement tool. (4) We assessed the content validity of the developed tool, MoveMEY, through interviews with parents of pre-school aged children (n = 12) following piloting of the tool. Results We developed an initial version of MoveMEY based on the format of an existing questionnaire and by mapping the content of questions to the guidelines. Co-design of MoveMEY resulted in changes to the format (e.g. short questionnaire to a seven-day diary) and content (e.g. inclusion of ‘general information’ questions on illness, disabilities and sleep disturbances; question on screen time before bed). Content validity assessment demonstrated that the items of MoveMEY were relevant and comprehensive for the assessment of children’s movement behaviours. MoveMEY was felt to be comprehensible, however, parental suggestions were implemented to finalise and improve MoveMEY (e.g. adding examples to questions aiming to detect moderate to vigorous physical activity). Conclusion MoveMEY is the first co-designed measurement tool that has relevance for assessing the movement behaviour guidelines of pre-school aged children. Parent/carer and topic relevant researcher involvement throughout the development process resulted in a seven-day daily reported activity diary that is comprehensive of children’s movement behaviours and comprehensible to parents and carers

Children's experiences of care on walking and cycling journeys between home and school in Healthy New Towns: Reframing active school travel

The Healthy New Town programme in England set out to ‘put health into place’ by supporting the design and construction of healthy places to live, including by creating safe environments for active travel. To explore the impact of this approach, this study examined how children and their families experienced school journeys in two contrasting Healthy New Towns in England, one an affluent new town in the early stages of construction and the other more economically deprived and established. We undertook photo-elicitation and go-along interviews with 24 children aged 7-12 years and semi-structured interviews with 17 caregivers. We found that experiences of care were important for children's school travel. In the ‘deprived’ town, opportunities for children to care and to be cared for were enjoyed, facilitated by routes with limited traffic, pockets of ‘nature’, and possibilities to encounter meaningful others. For families living in a town under construction, the need to negotiate unfinished travel infrastructure, and a sense of being ‘in limbo’, was experienced as an absence of care by planners and developers. Interventions to promote children's active travel should consider the role of care-full planning in facilitating walking and cycling journeys

A systematic review of the validity, reliability, and feasibility of measurement tools used to assess the physical activity and sedentary behaviour of pre-school aged children

Physical activity (PA) and sedentary behaviour (SB) of pre-school aged children are associated with important health and developmental outcomes. Accurate measurement of these behaviours in young children is critical for research and practice in this area. The aim of this review was to examine the validity, reliability, and feasibility of measurement tools used to assess PA and SB of pre-school aged children. Searches of electronic databases, and manual searching, were conducted to identify articles that examined the measurement properties (validity, reliability or feasibility) of measurement tools used to examine PA and/or SB of pre-school aged children (3–7 years old). Following screening, data were extracted and risk of bias assessment completed on all included articles. A total of 69 articles, describing 75 individual studies were included. Studies assessed measurement tools for PA (n = 27), SB (n = 5), and both PA and SB (n = 43). Outcome measures of PA and SB differed between studies (e.g. moderate to vigorous activity, step count, posture allocation). Most studies examined the measurement properties of one measurement tool only (n = 65). Measurement tools examined included: calorimetry, direct observation, combined heart rate and accelerometry, heart rate monitors, accelerometers, pedometers, and proxy report (parent, carer or teacher reported) measures (questionnaires or diaries). Studies most frequently assessed the validity (criterion and convergent) (n = 65), face and content validity (n = 2), test-retest reliability (n = 10) and intra-instrument reliability (n = 1) of the measurement tools. Feasibility data was abstracted from 41 studies. Multiple measurement tools used to measure PA and SB in pre-school aged children showed some degree of validity, reliability and feasibility, but often for different purposes. Accelerometers, including the Actigraph (in particular GT3X versions), Actical, ActivPAL and Fitbit (Flex and Zip), and proxy reported measurement tools used in combination may be useful for a range of outcome measures, to measure intensity alongside contextual information

Phylogeny and taxonomy of root-inhabiting Cryptosporiopsis species, and C. rhizophila sp. nov., a fungus inhabiting roots of several Ericaceae

Three Cryptosporiopsis species have thus far been isolated from roots of woody plants. A fourth species, which was recently isolated from roots of Calluna vulgaris, Erica tetralix, Vaccinium vitis-idaea, and V. myrtillus in The Netherlands, is described here as new. Sporulation on the natural substratum has not been observed and the morphological description of this fungus is therefore based on characters expressed on oatmeal and malt extract agars. The phenotypic characters indicated a close relationship with the other root-inhabiting species of Cryptosporiopsis and species of the associated teleomorph genus Pezicula. This relationship was confirmed by phylogenetic analyses using sequence data of the 5.8S nuclear rDNA and flanking internal transcribed spacers. In order to facilitate recognition of this possibly under-recognized category of root inhabitants, a key to the root-inhabiting Cryptosporiopsis species based on characters in vitro is given

Trends in maternal body mass index, health inequalities, and the impact of maternal obesity on NHS maternity services

The primary objective of the work presented in this thesis was to identify trends in maternal body mass index (BMI) over time, the demographic predictors of those women most at risk of being obese in pregnancy, health inequalities, and the impact of maternal obesity on maternity services. A mixed methodology utilised quantitative and qualitative research to address these objectives. Data were collated from 34 maternity units across England, including 619,323 deliveries between 1989 and 2007 inclusive. Analysis identified an increasing incidence of maternal obesity over time, regional differences in incidence, and significant inequalities with women residing in the highest levels of deprivation, and Black ethnic group. A systematic review was carried out including 49 studies investigating obesity and pregnancy outcomes with acute maternity resource implications. The meta-analysis found significantly increased odds of a number of outcomes, and concluded that maternal obesity had a considerable impact on maternity resources, and contributed towards a poorer prognosis for the mother and the baby during delivery and in the immediate post-partum period. Qualitative interviews and focus groups with 30 HCPs across eight NHS Trusts in the North East of England were carried out to identify barriers in implementing maternal obesity services, and to gain HCPs perspectives on what they felt was required in order to address maternal obesity effectively. The study identified the themes of ‘Service Development’, ‘Psychosocial Issues and Maternal Obesity Services’, ‘Information, Evidence, and Training’, and ‘Where to go From Here?’. Overall this programme of research has identified that maternal obesity is increasing over time and is significantly associated with health inequalities. The increase in maternal obesity has an impact on acute services, and HCPs feel that a holistic approach is required through partnership work in order to address maternal obesity effectively. This programme of research has primarily contributed to the knowledge of maternal obesity with the provision of the first national level statistics for trends in maternal obesity. The research has also provided a holistic view of the impact of obesity in pregnancy on maternity services, including the impact on resources and the issues relating to addressing the maternal obesity in clinical practice. The research has also identified aspects of service that need to be improved, and knowledge gaps in how to move services forward to effective address maternal obesity. The contribution of this research to the knowledge base is emphasised in the journal pre-publications, dissemination through UK and European, and international conference presentations, being an invited speaker at a number of conferences in the UK, and I received the 2007 Association for the Study of Obesity (ASO) Student Researcher Award for producing exemplary work in the study of obesity.EThOS - Electronic Theses Online ServiceGBUnited Kingdo

Determinants of Change in Physical Activity in Children 0-6 years of Age: A Systematic Review of Quantitative Literature.

Background Understanding the determinants of children’s health behaviours is important to develop successful behaviour-change interventions. Objective We aimed to synthesise the evidence around determinants (‘preceding predictors’) of change in physical activity (PA) in young children (0–6 years of age). Methods As part of a suite of reviews, prospective quantitative studies investigating change in physical activity in children aged 0–6 years were identified from eight databases (to October 2015): MEDLINE, Embase, CINAHL, PsycINFO, Web of Knowledge, British Nursing Index, Applied Social Sciences Index and Abstracts, and Sociological Abstracts. Determinants and direction of association were extracted, described and synthesised according to the socio-ecological model (individual, interpersonal, organisational, community, policy). Results Forty-four determinants, predominantly in the interpersonal and organisational domains, were reported across 44 papers (six prospective cohort, 38 interventional); 14 determinants were assessed in four or more papers. Parental monitoring showed a consistent positive association with change in PA; provider training was positively associated with change in children’s moderate-to-vigorous PA only. Five (sex, parental goal setting, social support, motor skill training and increased time for PA) showed no clear association. A further seven (child knowledge, parental knowledge, parental motivation, parenting skills, parental self-efficacy, curriculum materials and portable equipment) were consistently not associated with change in children’s PA. Maternal role-modelling was positively associated with change in PA in all three studies in which it was examined. Conclusions A range of studied determinants of change in young children’s PA were identified, but only parental monitoring was found to be consistently positively associated. More evidence dealing with community and policy domains from low-/middle-income countries and about lesser-explored modifiable family- and childcare-related determinants is required.

csal1 Is Controlled by a Combination of FGF and Wnt Signals in Developing Limb Buds

While some of the signaling molecules that govern establishment of the limb axis have been characterized, little is known about the downstream effector genes that interpret these signals. In Drosophila, the spalt gene is involved in cell fate determination and pattern formation in different tissues. We have cloned a chick homologue of Drosophila spalt, which we have termed csal1, and this study focuses on the regulation of csal1 expression in the limb bud. csal1 is expressed in limb buds from HH 17 to 26, in both the apical ectodermal ridge and the distal mesenchyme. Signals from the apical ridge are essential for csal1 expression, while the dorsal ectoderm is required for csal1 expression at a distance from the ridge. Our data indicate that both FGF and Wnt signals are required for the regulation of csal1 expression in the limb. Mutations in the human homologue of csal1, termed Hsal1/SALL1, result in a condition known as Townes–Brocks syndrome (TBS), which is characterized by preaxial polydactyly. The developmental expression of csal1 together with the digit phenotype in TBS patients suggests that csal1 may play a role in some aspects of distal patterning
