Remote physical activity intervention to promote physical activity and health in adolescent girls (the HERizon project): a multi-arm, pilot randomised trial.

BACKGROUND: Engaging in physical activity (PA) during adolescence is beneficial for health and positive development. However, most adolescent girls have low PA levels, and there is a need for interventions outside of school hours. This pilot randomised controlled trial aimed to explore the preliminary effectiveness of three different remote PA interventions in increasing adolescent girls' moderate-to- vigorous PA (MVPA), fitness and psychosocial outcomes. METHODS: Girls living in the UK or Ireland, aged between 13 and 16 years old, who wished to increase their activity levels, were eligible for the study. Using a random number generator, participants (n = 153; 14.8y ± 1.4) were randomised into one of three 12-week intervention groups (i) PA programme, (ii) Behaviour change support, or (iii) Combined PA programme and Behaviour change support, or (iv) a Comparison group. Outcome measures included accelerometer and self-reported PA, physical fitness (cardiorespiratory fitness; 20 m shuttle run, muscular endurance; push up, muscular strength; long jump), and psychosocial assessments (perceived competence; body appreciation; self-esteem; behavioural regulation). Linear mixed models were used to analyse differences between each intervention arm and the comparison group immediately postintervention (12 weeks) and at follow up (3-months post-intervention), while adjusting for potential confounders. RESULTS: Participation in the PA programme group was associated with higher perceived competence (0.6, 95% CI 0.1 to 1.2), identified regulation (0.7, 95% CI 0.2 to 1.1) and intrinsic motivation (0.9, 95% CI 0.2 to 1.6) at post-intervention. Participation in the Behaviour change group was associated with higher perceived competence at post-intervention (0.6, 95% CI 0.1 to 1.2), and higher push-up scores at the 3-month follow-up (4.0, 95% CI 0.0 to 7.0). Participation in the Combined group was also associated with higher perceived competence at post-intervention (0.8, 95% CI 0.2 to 1.4), and higher push-up scores at the 3-month follow-up (5.0, 95% CI 1.0 to 8.0). No other significant differences were found between the intervention arms and the comparison group. CONCLUSION: Results suggest perceived competence increased across all intervention arms, while the PA programme group enhanced autonomous motivation in the short term. Intervention arms with behaviour change support appear most promising in improving muscular endurance. However, a larger scale trial is needed for a better understanding of between-group differences and the impact of intervention arms on MVPA and fitness, given the small sample size and short-term follow-up.

Differential Associations of Total and Context-Specific Sedentary Time with Depressive Symptoms Among Adolescents: Results from Ireland's CSPPA Study.

BACKGROUND: Higher levels of sedentary behaviour (SB) and screen-time are associated with greater symptoms of depression in adolescents, but the effect of the type and context of SB and screen-time remains underexplored. As part of a nationally-representative observational study, the current cross-sectional study examined associations between SB, screen-time and depressive symptoms among 422 adolescents (13.5 ± 0.92 years; 125 female) in the Republic of Ireland. METHOD: Participants completed the Quick Inventory of Depressive Symptomatology and self-reported weekly SB, categorised into mentally-active screen-time (e.g., computer use for fun), mentally-passive screen-time (e.g., television viewing) and mentally-active non-screen-based SB (e.g., reading). Mann-Whitney U tests and Kruskal-Wallis H tests examined differences in screen-time and depressive symptoms by relevant covariates. Linear regression quantified crude and adjusted associations between total SB and mentally-active and mentally-passive screen-time and SB, and depressive symptoms. RESULTS: Crude and adjusted linear regressions showed total SB was significantly, positively associated with depressive symptoms (unadjusted: ß = 0.27, p = 0.002, adjusted: ß = 0.27, p = 0.002). When type and context were examined in the same model, only mentally-active screen-time was positively associated with depressive symptoms (unadjusted: ß = 0.37, p = 0.009, adjusted: ß = 0.39, p = 0.007). CONCLUSION: Differential associations between total SB and mentally-active screen-time and SB, versus mentally-passive screen-time, and depressive symptoms among Irish adolescents were observed. Findings highlight the importance of investigating the context and type of SB and screen-time in adolescents.

Co-design of a school-based physical activity intervention for adolescent females in a disadvantaged community: insights from the Girls Active Project (GAP).

BACKGROUND: Globally, adolescents' physical activity (PA) participation rates are low, particularly among lower socioeconomic groups, with females consistently the least active. The aim of this study was to co-design, with adolescent females, a school-based PA intervention in a single-sex, females-only designated disadvantaged post-primary school in Ireland. This involved using the Behaviour Change Wheel (BCW) and Public and Patient Involvement (PPI). This paper outlines the novel methodological approach taken. METHODS: The three stages 1) understand the behaviour, 2) identify intervention options, and 3) identify content and implementation options of the BCW guide is described. A student PPI Youth Advisory Group (YAG) (n = 8, aged 15-17) was established. Mixed-methods were used with students (n = 287, aged 12-18) and teachers (n = 7) to capture current self-reported PA levels and to identify factors influencing adolescent females' PA behaviour in their school setting. The intervention options, content and implementation options were identified through discussion groups with the YAG. The Template for Intervention Description and Replication (TIDieR) checklist was used to specify details of the intervention. RESULTS: Just 1.4% of the students in this sample reported meeting the recommended PA guidelines. Students identified having more 'time' as the strongest predictor to becoming more active in school (Mean = 4.01, 95% CI 3.91 to 4.12). Social influences, environmental context and resources, behavioural regulation, beliefs about capabilities, goals, and reinforcement emerged from the qualitative data as factors influencing PA behaviour at school. The BCW co-design process resulted in the identification of seven intervention functions, four policy categories and 21 Behaviour Change Techniques. The Girls Active Project (GAP) intervention, a peer-led, after-school PA programme was proposed. CONCLUSIONS: This paper describes how the BCW, a comprehensive, evidence-based, theory-driven framework was used in combination with PPI to co-design a school-based intervention aimed to increase adolescent females' PA levels. This approach could be replicated in other settings to develop targeted behavioural interventions in populations with specific demographic characteristics.

Are all domains created equal? An exploration of stakeholder views on the concept of physical literacy.

BACKGROUND: Developing physical literacy at population levels provides a transformative appeal for those working in sport, health, education, recreation and physical activity settings. Interdisciplinary approaches to development of policy in this area is recommended. The purpose of this study was to gather empirical data from key stakeholders working with young people in areas related to physical literacy across the Republic of Ireland and Northern Ireland, to capture their current understanding and awareness of the physical literacy to help inform the development of the first all-island consensus statement for physical literacy. METHODS: A total of 1,241 participants (52% male), from a range of stakeholder groups (health, physical activity, sport, recreation and education) completed a researcher developed physical literacy questionnaire. A one-way MANOVA was carried out to investigate differences across stakeholder grouping in terms of perceived importance of three domains of physical literacy. Overlap of independent confidence intervals was analysed to determine importance of the physical literacy domains within stakeholder grouping. RESULTS: A majority (63%) of respondents indicated they were aware of an existing definition of physical literacy, but this varied by stakeholder group (e.g. 86% for higher education, versus 47% of coaches). Participants working in higher education (69%), or working as physical education specialists (67%), were more likely to rate themselves as experts or near experts in physical literacy, while coaches, education generalists, and decision makers were more likely rate themselves as having no expertise (9%, 12% and 12% respectively). Non-specialist teachers and physical education teachers rated the importance of all domains of physical literacy significantly higher than decision makers, and significantly higher than coaches in the cognitive and affective domains. All stakeholders significantly rated the importance of the physical/psychomotor domain of physical literacy higher than the affective or cognitive domains of physical literacy. CONCLUSIONS: Differences observed across stakeholder groups underline the importance of developing a shared vision for physical literacy, and the need to clarify and gain consensus on a definition of the term and its domains. Engaging and understanding the voice of stakeholders is critical in ensuring the relevance, ownership of and commitment to physical literacy statement operationalisation.

A pragmatic evaluation of the primary school Be Active After-School Activity Programme (Be Active ASAP).

The period after school represents an opportunity to engage children in physical activity (PA) programmes in schools. The purpose of this study was to evaluate the effect of an afterschool programme, delivered in schools, on children's participation in and attitudes to PA. Ten schools took part in this non-randomized controlled trial (five experimental and five control schools). Experimental schools participated in an after-school programme delivered by teachers and parents for 50 min per week. Outcome measures included device-measured PA, self-report youth PA behaviour and parental perceptions of the school environment. Measurements took place at baseline, and mean follow-up was at 10 weeks. Data were collected from 196 participants, with a mean age of 8.1 ± 0.8 years. Mean daily minutes of moderate-to-vigorous physical activity (MVPA) for the entire sample at baseline was 69.9 ± 23.3. While both groups presented a decline in MVPA levels, there was a significant difference in the change from baseline to follow-up (P = 0.043) of min/day MVPA between the control group (-13.2 ± 23.9) and the experimental group (-0.9 ± 25.2). This programme may help maintain MVPA levels, with children exposed to the intervention experiencing a significantly lower decline in MVPA than their control counterparts.

TGMD-3 short version: Evidence of validity and associations with sex in Irish children.

This study examined the internal structure and evidence of validity of the Test of Gross Motor Development 3rd edition (TGMD-3) in primary school aged children. Participants (n = 1608, 47% girls, age range 5-11 years, mean age 9.2 ± 2.04) were recruited from Irish schools across twelve counties (56% rural, 44% urban). The TGMD-3 was used to measure FMS proficiency (Ulrich, 2020). A two-factor model (13 skills) was used and confirmatory indexes were calculated. The Bayesian criteria and the Composite Reliability were employed to evaluate alternative models. Relationships between the final model proposed with age, sex and BMI were calculated using a network analysis. Mplus 8.0 and Rstudio were used. A two-factor model (locomotion and object control) with adequate values (> 0.30) for the seven skills (gallop, hop, jump, two-hand strike, bounce, catch, overhand throw) presented excellent indexes. The skills with the highest indicator of strength centrality in the network were bounce and catch for both boys and girls and hop for boys and horizontal jump for girls. This study evidences the validity and reliability of the internal structure of the TGMD-3 and demonstrates that a short version of the TGMD-3, comprising seven skills is a valid measure of FMS in this population.

Understanding disadvantaged adolescents' perception of health literacy through a systematic development of peer vignettes.

BACKGROUND: Adolescence represents a crucial phase of life where health behaviours, attitudes and social determinants can have lasting impacts on health quality across the life course. Unhealthy behaviour in young people is generally more common in low socioeconomic groups. Nevertheless, all adolescents should have a fair opportunity to attain their full health potential. Health literacy is positioned as a potential mediating factor to improve health, but research regarding health literacy in adolescents and socially disadvantaged populations is limited. As part of Phase one of the Ophelia (OPtimising HEalth LIterAcy) framework, The purpose of this study was to explore the perceptions of socially disadvantaged Irish adolescents in relation to health literacy and related behaviours, and utilise this data to develop relevant vignettes. METHODS: A convergent mixed method design was used to co-create the vignettes. Questionnaires were completed by 962 adolescents (males n = 553, females n = 409, Mean age = 13.97 ± 0.96 years) from five participating disadvantaged schools in Leinster, Ireland. Focus groups were also conducted in each school (n = 31). Results were synthesised using cluster and thematic analysis, to develop nine vignettes that represented typical male and female subgroups across the schools with varying health literacy profiles. These vignettes were then validated through triangular consensus with students, teachers, and researchers. DISCUSSION: The co-creation process was a participatory methodology which promoted the engagement and autonomy of the young people involved in the project. The vignettes themselves provide an authentic and tangible description of the health issues and health literacy profiles of adolescents in this context. Application of these vignettes in workshops involving students and teachers, will enable meaningful engagement in the discussion of health literacy and health-related behaviours in Irish young people, and the potential co-designing of strategies to address health literacy in youth. CONCLUSION: As guided by the Ophelia framework, the use of authentic, interactive and participatory research methods, such as the co-creation of vignettes, is particularly important in groups that are underserved by traditional research methods. The approach used in this study could be adapted to other contexts to represent and understand stakeholders' perceptions of health, with a view to explore, and ultimately improve, health literacy.

School-based interventions modestly increase physical activity and cardiorespiratory fitness but are least effective for youth who need them most: an individual participant pooled analysis of 20 controlled trials.

OBJECTIVES: To determine if subpopulations of students benefit equally from school-based physical activity interventions in terms of cardiorespiratory fitness and physical activity. To examine if physical activity intensity mediates improvements in cardiorespiratory fitness. DESIGN: Pooled analysis of individual participant data from controlled trials that assessed the impact of school-based physical activity interventions on cardiorespiratory fitness and device-measured physical activity. PARTICIPANTS: Data for 6621 children and adolescents aged 4-18 years from 20 trials were included. MAIN OUTCOME MEASURES: Peak oxygen consumption (VO2Peak mL/kg/min) and minutes of moderate and vigorous physical activity. RESULTS: Interventions modestly improved students' cardiorespiratory fitness by 0.47 mL/kg/min (95% CI 0.33 to 0.61), but the effects were not distributed equally across subpopulations. Girls and older students benefited less than boys and younger students, respectively. Students with lower levels of initial fitness, and those with higher levels of baseline physical activity benefitted more than those who were initially fitter and less active, respectively. Interventions had a modest positive effect on physical activity with approximately one additional minute per day of both moderate and vigorous physical activity. Changes in vigorous, but not moderate intensity, physical activity explained a small amount (~5%) of the intervention effect on cardiorespiratory fitness. CONCLUSIONS: Future interventions should include targeted strategies to address the needs of girls and older students. Interventions may also be improved by promoting more vigorous intensity physical activity. Interventions could mitigate declining youth cardiorespiratory fitness, increase physical activity and promote cardiovascular health if they can be delivered equitably and their effects sustained at the population level.

Clusters of Adolescent Physical Activity Tracker Patterns and Their Associations With Physical Activity Behaviors in Finland and Ireland: Cross-Sectional Study.

BACKGROUND: Physical activity trackers (PATs) such as apps and wearable devices (eg, sports watches, heart rate monitors) are increasingly being used by young adolescents. Despite the potential of PATs to help monitor and improve moderate-to-vigorous physical activity (MVPA) behaviors, there is a lack of research that confirms an association between PAT ownership or use and physical activity behaviors at the population level. OBJECTIVE: The purpose of this study was to examine the ownership and use of PATs in youth and their associations with physical activity behaviors, including daily MVPA, sports club membership, and active travel, in 2 nationally representative samples of young adolescent males and females in Finland and Ireland. METHODS: Comparable data were gathered in the 2018 Finnish School-aged Physical Activity (F-SPA 2018, n=3311) and the 2018 Irish Children's Sport Participation and Physical Activity (CSPPA 2018, n=4797) studies. A cluster analysis was performed to obtain the patterns of PAT ownership and usage by adolescents (age, 11-15 years). Four similar clusters were identified across Finnish and Irish adolescents: (1) no PATs, (2) PAT owners, (3) app users, and (4) wearable device users. Adjusted binary logistic regression analyses were used to evaluate how PAT clusters were associated with physical activity behaviors, including daily MVPA, membership of sports clubs, and active travel, after stratification by gender. RESULTS: The proportion of app ownership among Finnish adolescents (2038/3311, 61.6%) was almost double that of their Irish counterparts (1738/4797, 36.2%). Despite these differences, the clustering patterns of PATs were similar between the 2 countries. App users were more likely to take part in daily MVPA (males, odds ratio [OR] 1.27, 95% CI 1.04-1.55; females, OR 1.49, 95% CI 1.20-1.85) and be members of sports clubs (males, OR 1.37, 95% CI 1.15-1.62; females, OR 1.25, 95% CI 1.07-1.50) compared to the no PATs cluster, after adjusting for country, age, family affluence, and disabilities. These associations, after the same adjustments, were even stronger for wearable device users to participate in daily MVPA (males, OR 1.83, 95% CI 1.49-2.23; females, OR 2.25, 95% CI 1.80-2.82) and be members of sports clubs (males, OR 1.88, 95% CI 1.55-2.88; females, OR 2.07, 95% CI 1.71-2.52). Significant associations were observed between male users of wearable devices and taking part in active travel behavior (OR 1.39, 95% CI 1.04-1.86). CONCLUSIONS: Although Finnish adolescents report more ownership of PATs than Irish adolescents, the patterns of use and ownership remain similar among the cohorts. The findings of our study show that physical activity behaviors were positively associated with wearable device users and app users. These findings were similar between males and females. Given the cross-sectional nature of this data, the relationship between using apps or wearable devices and enhancing physical activity behaviors requires further investigation.

The effect of sport for LIFE: all island in children from low socio-economic status: a clustered randomized controlled trial.

BACKGROUND: School-based interventions offer the opportunity to increase physical activity, health-related quality of life (HRQOL) and nutritional behaviours, yet methodological limitations hinder current research, particularly among under-represented children from low socio-economic status (SES). The aim was to determine the effect of a 12-week physical activity programme, Sport for LIFE: All Island (SFL:AI), on physical activity levels, HRQOL, and nutritional attitudes and behaviours in children of low SES across the island of Ireland. METHODS: A 2 (groups) × 4 (data collection points) clustered randomised controlled trial was conducted comprising an intervention group who received SFL:AI for 12 weeks, and a waiting-list control condition. In total 740 children (381 boys, 359 girls) aged 8-9 years (mean = 8.7; SD = .50) from 27 schools across four regions of Ireland (Ulster, Leinster, Connacht and Munster) took part. Physical activity was measured by accelerometers, and children completed a validated questionnaire at baseline, mid (i.e. 6-weeks), post-intervention (i.e. 12 weeks) and follow-up (i.e. 3 months post-intervention). RESULTS: No significant interaction effects for the intervention were found on any of the study outcomes. Main effects were reported for physical well-being, parental relations and autonomy and financial resources, as well as sweetened beverages, environment and intake, and attitude to vegetables. However, these changes were not statistically attributable to the intervention. CONCLUSIONS: It remains unclear if school-based physical activity interventions can improve HRQOL through physical activity with children from low SES. Logistical and methodological considerations are outlined to explore the null effect of the programme, and to provide suggestions for future research and practice.

Moving Well-Being Well: Investigating the maturation of fundamental movement skill proficiency across sex in Irish children aged five to twelve.

Fundamental movement skills (FMS) are the basic building blocks of more advanced, complex movements required to participate in physical activity. This study examined FMS proficiency across the full range of Irish primary school children (n = 2098, 47% girls, age range 5-12 years). Participants were assessed using the Test of Gross Motor Development, 3rd edition (TGMD-3), Victorian Fundamental Movement skills manual, and the balance subtest from the Bruininks-Oseretsky Test of Motor Proficiency 2 (BOT-2). Independent sample t-tests and a one way between groups ANOVA with planned comparisons were used analyse sex and age differences. Mastery or near mastery of skills ranged from 16% for overhand throw, to 75.3% for run. Girls scored significantly higher than boys in the locomotor and balance subtests with the boys outperforming the girls in object control skills. Improvements in ability can be seen over time (F(8,1968) = 70.18, p < 0.001), with significant increases in FMS proficiency seen up to the age of 10, after which proficiency begins to decline. The findings demonstrate the low levels of FMS proficiency amongst Irish primary school children, the differences between sex that exist, and highlights the need for more programmes that focus on developing these FMS at an early age.

A comparison of physical activity, physical fitness levels, BMI and blood pressure of adults with intellectual disability, who do and do not take part in Special Olympics Ireland programmes: Results from the SOPHIE study.

People with an intellectual disability are less physically active, live more sedentary lives, have lower fitness levels and are more likely to be overweight or obese than the general population. No evidence exists on the impact of participation in Special Olympics Ireland (SOI) on physical activity and physical fitness levels. Adults with intellectual disabilities (16-64 years) were recruited from services and SOI clubs. Physical measures included waist circumference, height, weight, blood pressure, heart rate and 6-min walking test. Self-report questionnaires gathered data on physical activity levels. Actigraph (GT3X) accelerometers were used to gain an objective measure of physical activity. SOI participants accumulated more moderate to vigorous physical activity per day, had higher fitness levels and more positive health profile scores than those not taking part in SOI. SOI has the potential to make a positive difference to people's physical health and subsequently their overall health and well-being.

The relationship between fundamental movement skill proficiency and physical self-confidence among adolescents.

This study aims to assess fundamental movement skill (FMS) proficiency, physical self-confidence levels, and the relationship between these variables and gender differences among adolescents. Three hundred and ninety five adolescents aged 13.78 years (SD = ±1.2) from 20 schools were involved in this study. The Test of Gross Motor Development-2nd Edition (TGMD), TGMD-2 and Victorian Skills Manual were used to assess 15 FMS. Participants' physical self-confidence was also assessed using a valid skill-specific scale. A significant correlation was observed between FMS proficiency and physical self-confidence for females only (r = 0.305, P < 0.001). Males rated themselves as having significantly higher physical self-confidence levels than females (P = 0.001). Males scored significantly higher than females in FMS proficiency (P < 0.05), and the lowest physical self-confidence group were significantly less proficient at FMS than the medium (P < 0.001) and high physical self-confidence groups (P < 0.05). This information not only highlights those in need of assistance to develop their FMS but will also facilitate in the development of an intervention which aims to improve physical self-confidence and FMS proficiency.

An examination of the nutritional intake and anthropometric status of individuals with intellectual disabilities: Results from the SOPHIE study.

The prevalence of obesity appears greater in people with intellectual disabilities than those in the general population. This study aimed to examine the nutritional intake and anthropometric status of individuals with intellectual disabilities. Participants aged 16-64 years were recruited from intellectual disability service provider organizations ( n = 131). Data were collected using questionnaires; 4-day food dairies and weight, height and waist circumference measurements. Participants' mean body mass index (BMI) was 29.4 kg/m2 ± 6.1, 2.4% were underweight, 22.6% were normal weight, 28.2% were overweight and 46.8% were obese. Having a diagnosis of Down syndrome ( p = 0.03) was associated with increasing BMI. Increasing waist circumference was associated with increasing severity of ID ( p = 0.04). The mean-reported energy intake was 1890 kcal/day. Mean energy intakes from sugar, fat and saturated fat were above recommendations and few participants met micronutrient recommended daily amounts. This study highlights the alarming prevalence of overweight and obesity and poor diet quality of individuals with intellectual disabilities.

The relationship between adolescents' physical activity, fundamental movement skills and weight status.

The aim of this study was to determine if a potential relationship among physical activity (PA), fundamental movement skills and weight status exists amongst early adolescent youth. Participants were a sample of 85 students; 54 boys (mean age = 12.94 ± 0.33 years) and 31 girls (mean age = 12.75 ± 0.43 years). Data gathered during physical education class included PA (accelerometry), fundamental movement skills and anthropometric measurements. Standard multiple regression revealed that PA and total fundamental movement skill proficiency scores explained 16.5% (P < 0.001) of the variance in the prediction of body mass index. Chi-square tests for independence further indicated that compared with overweight or obese adolescents, a significantly higher proportion of adolescents classified as normal weight achieved mastery/near-mastery in fundamental movement skills. Results from the current investigation indicate that weight status is an important correlate of fundamental movement skill proficiency during adolescence. Aligned with most recent research, school- and community-based programmes that include developmentally structured learning experiences delivered by specialists can significantly improve fundamental movement skill proficiency in youth.

People with intellectual disability and their families' perspectives of Special Olympics Ireland: Qualitative findings from the SOPHIE study.

Previous research has highlighted that while involvement in Special Olympics can have benefits for athletes and their families, there can also be many barriers to participation. This qualitative study, which was part of a large mixed-method study, examined the experiences and perspectives of people with intellectual disability, their families and staff who work with them, about Special Olympics Ireland (SOI). A total of 47 participants (15 athletes, 6 non-athletes, 18 family members and 8 staff members) participated in focus group and individual interviews. Supplemental data, gathered as part of the larger study extracted from open-ended survey questions completed by 97 family members also informed this element. Findings revealed four main themes: impact of participation on athletes, impact of involvement on families, barriers to participation and how to enhance participation rates. Involvement in Special Olympics impacted positively on the quality of life of athletes and families. Enhanced availability of user-friendly information and service accessibility were important drivers identified for enhancing participation rates in Special Olympics.

Validity of a two-item physical activity questionnaire for assessing attainment of physical activity guidelines in youth.

BACKGROUND: As physical activity is important for health and well-being, it is essential to monitor population prevalence of physical activity. Surveillance is dependent on the use of valid and reliable measurement tools. The PACE+ questionnaire is used globally in youth and has acceptable reliability; however it has not been validated in a European sample. The purpose of this study is to validate this instrument in a sample of 10-18 year old Irish youth. METHODS: Participants (n = 419, 45.7 % male) completed the PACE+ two-item questionnaire and were asked to wear an Actigraph accelerometer for eight consecutive days. Freedson cut-points were used to estimate moderate to vigorous physical activity from accelerometer counts. Analyses compared self-report and accelerometry data in participants with (1) ≥5 and (2) seven valid accelerometer days. Calculations were performed for the whole sample, and were stratified by sex and school level (primary; post-primary). RESULTS: Spearman correlations between self-reported physical activity levels and accelerometry derived minutes of moderate-to-vigorous physical activity per day were small (r = 0.27; seven valid days) to moderate (r = 0.34; ≥5 valid days). Higher correlations were found in older participants (post-primary r = 0.39; primary r = 0.24) and females (r = 0.39; males r = 0.27) using ≥5 valid days. The agreement level was high (68-96 %). The accuracy of classifying those not meeting the guidelines (specificity) was moderate to high (59-100 %). CONCLUSIONS: The PACE+ self-report instrument has acceptable validity for assessing non-achievement of the adolescent physical activity recommendations. The validity is higher in females and increases with age. The continued use of the tool is recommended and will allow for comparability between studies, tracking of physical activity over time including trends in youth population prevalence.

Youth-Physical Activity Towards Health: evidence and background to the development of the Y-PATH physical activity intervention for adolescents.

BACKGROUND: Despite known benefits of regular physical activity for health and well-being, many studies suggest that levels of physical activity in young people are low, and decline dramatically during adolescence. The purpose of the current research was to gather data on adolescent youth in order to inform the development of a targeted physical activity intervention. METHODS: Cross-sectional data on physical activity levels (using self report and accelerometry), psychological correlates of physical activity, anthropometic characteristics, and the fundamental movement skill proficiency of 256 youth (53% male, 12.40 ± 0.51 years) were collected. A subsample (n = 59) participated in focus group interviews to explore their perceptions of health and identify barriers and motivators to participation in physical activity. RESULTS: Findings indicate that the majority of youth (67%) were not accumulating the minimum 60 minutes of physical activity recommended daily for health, and that 99.5% did not achieve the fundamental movement skill proficiency expected for their age. Body mass index data showed that 25% of youth were classified as overweight or obese. Self-efficacy and physical activity attitude scores were significantly different (p < 0.05) between low, moderate and high active participants. Active and inactive youth reported differences in their perceived understanding of health and their barriers to physical activity participation, with active youth relating nutrition, exercise, energy and sports with the definition of 'being healthy', and inactive youth attributing primarily nutritional concepts to 'being healthy'. CONCLUSIONS: Data show a need for targeting low levels of physical activity in youth through addressing poor health related activity knowledge and low fundamental movement skill proficiency. The Y-PATH intervention was developed in accordance with the present study findings; details of the intervention format are presented.

Investigating physical activity levels in adults who are blind and vision impaired.

BACKGROUND: It is well established that meeting physical activity (PA) guidelines has a range of physical and mental health benefits. For people who are blind and vision impaired (BVI) there may be additional benefits in terms of social inclusion and the prevention of sight deterioration. OBJECTIVE: This study aimed to quantify PA levels, barriers to and motivators for PA in adults who are BVI. METHODS: PA levels, perceived barriers to, and motivators for PA were measured via questionnaire of 310 self-identifying BVI adults (n = 310 mean age = 29.77 ± 11.37, 55.8% male). RESULTS: PA levels were low, with 21.7% meeting PA guidelines. Median PA levels were not statistically significantly different between different age groups. There was no significant difference between genders, though mean days of PA for males was 0.382 days lower than for females. There was a significant difference between PA levels between the "no vision" (B1) and "useful vision" (B3) groups (p = 0.027), and the "no vision" (B1) and the "low vision" (B2) groups (p = 0.003). Transport (54.8%) and lack of access to enjoyable activities (47.0%) were the most commonly cited barriers, while "to relax" (36.4%) and "to have fun" (35.6%) were most commonly cited as very important motivators. CONCLUSIONS: This study provides a valuable insight into the low levels of PA that persist amongst adults with BVI. Future research should seek to gain a deeper understanding of the PA barriers, motivators and facilitators in this cohort.
