RESUMEN
BACKGROUND: In Europe, physical activity levels tend to be lower in ethnic minority groups than the general population. Interventions and policies based on research examining isolated determinants of physical activity have had limited success in increasing physical activity levels. This study used systems dynamics theory and the capability approach theoretical framework to develop a conceptual model of how individual characteristics, institutional and physical environments and the migration context may interact to promote or hinder physical activity in ethnic minority groups living in Europe. METHODS: A systematic update of Langøien et al.'s 2017 review of the determinants of physical activity in ethnic minority groups living in Europe was conducted. Our target population included individuals of all ages who reported a familial migration background from any low- and middle-income countries or belonging to minority indigenous population in Europe. Outcomes pertaining to non-work related physical activity of light, moderate or vigorous intensity performed in any setting were included. Included studies provided an evidence base from which to derive the causal loop diagrams comprising our conceptual model. Sub-system causal loop diagrams were interpreted in co-author review sessions to explicate non-linear system mechanisms, such as reinforcing and balancing feedback loops. RESULTS: Forty-one studies were identified, of which the majority was qualitative. The conceptual model consisted of 4 causal loop diagrams relating to psychosocial constructs; sociocultural constructs; health and health communication and social and material resources, in interaction with environmental/migration context. Four hypothetical mechanisms were identified, e.g. hypothesizing that participation in organised activities leads to increased self-efficacy, thereby enabling further participation. CONCLUSIONS: This study contributes an evidence-based conceptual systems model which elucidates how low levels of physical activity in ethnic minority groups in Europe could be supported by reinforcing and balancing mechanisms involving factors relating to physical and institutional environments, migration context and individuals. A pluralistic approach to literature review, integrating complexity methods such as CLDs into more conventional systematic literature review, supports novel insights into how factors could interact to support persistently low levels of activity, moving beyond the identification of potential relationships between isolated factors to indicating the ways in which these relationships are sustained and could be modified by intervention or policy.

Background: Move for Life (MFL) is a theory-informed intervention that was developed to augment established physical activity (PA) programmes and enable inactive adults aged 50 years and older to be more active. This study examined the feasibility of MFL and sought to provide evidence of its potential for improving PA and associated health outcomes. Methods: A 3-arm cluster randomised feasibility trial compared MFL intervention, usual provision (UP) and control (CON) groups at baseline (T0), post-intervention (T1, at 8, 10 or 12- weeks) and 6-month follow up (T2). We used purposive sampling strategies to recruit participants according to characteristics of interest. Feasibility outcomes assessed recruitment, fidelity, adherence, retention and data completion rates based on pre-set criteria. Primary outcomes were accelerometer-based moderate-to-vigorous intensity PA (MVPA) and self-reported compliance with physical activity guidelines (PAGL). Secondary outcomes included light intensity PA (LiPA), standing time, sedentary time, body composition (adiposity), physical function and psychological well-being. We used linear mixed models (continuous outcomes) or generalized estimated equations (categorical outcomes) to estimate group differences over time in the study outcomes. Results: Progression criteria for feasibility outcomes were met, and 733 individuals were recruited. Considering a 6-month period (T0-T2), while self-reported compliance with PAGL increased in MFL relative to UP and CON and in UP relative to CON, standing time decreased in MFL relative to CON and sedentary time increased in the latter compared to UP. Waist circumference decreased in MFL relative to UP and CON. MFL outperformed UP in the Timed Up and Go Test while MFL and UP increased the distance covered in the Six-Minute Walk Test compared to CON. Psychological well-being increased in MFL relative to CON (all p < 0.05). Conclusion: Findings show that MFL is feasible, while data are promising with regards to the potential of improving community PA programmes for adults aged 50 or more years.

BACKGROUND: Current literature reports a gap between development of effective interventions to promote physical activity and the systematic uptake into real-world settings. Factors relating to implementation and scale-up of physical activity interventions have been examined, however the perspectives of multiple stakeholders from different domains are not well researched. The purpose of this study was to examine the perceived factors related to physical activity intervention implementation and scale-up in different domains from different stakeholders on the island of Ireland. METHODS: Practitioners, researchers, funders and policy makers in Ireland were invited to take part in a semi-structured interview exploring factors related to the implementation and scale-up of eleven different physical activity interventions. A thematic analysis was conducted to identify factors related to the implementation and scale-up of the included interventions. The data collection and analysis were guided by the Consolidated Framework for Implementation Research. RESULTS: Thirty-eight participants took part in the interviews which identified factors related to 1) intervention planning and practical considerations; 2) organisational structures, staffing and resources related to delivery; 3) reflection, evaluation and updating of the intervention; and 4) practical consideration related to scale-up. Furthermore, participants referred to the ongoing commitment, engagement, and support needed throughout the implementation process. CONCLUSIONS: Future research and practice needs to consider how different factors are experienced at different implementation stages and by the different stakeholder groups involved. The findings highlight multiple inter-related factors that influence the implementation and scale-up of physical activity interventions, but also identifies many strategies that can be utilised to aid future successes.

BACKGROUND: The 'MED-WELL' programme is a combined exercise and educational intervention designed to promote well-being among medical students and educate students about prescribing exercise as medicine in clinical practice. Due to COVID-19 public health restrictions of social distancing the 'MED-WELL' programme was offered online instead of in-person in 2021. The aim of this study is to compare the experiences of participants in the 'MED-WELL' programme online to those that previously participated in the same programme in-person to understand the student experience and optimize programme delivery. METHODS: Purposive sampling was used to recruit 20 participants to a qualitative study using semi-structured interviews. Ten study participants took part in the 'MED-WELL' programme when it was offered in-person, and the other ten study participants took part in the programme when it was offered online. All interviews were audio-recorded and transcribed using Microsoft Teams. A combined inductive and deductive approach was used for analysis. An inductive thematic analysis was utilized to categorize data into higher order codes, themes, and overarching themes. The theory of online learning provided the theoretical framework for a deductive approach. RESULTS: Analysis of the data produced five overarching themes: 'student-student', 'student-teacher', 'student-content', 'student-environment', and 'effects of a pandemic'. The first four themes detail distinct types of interaction that participants had with various entities of the 'MED-WELL' programme and the effects that these interactions had on participant experiences. 'Effects of a pandemic' refers to the context of delivering the 'MED-WELL' programme online during a pandemic and how this mode of delivery influenced participants and the programme. CONCLUSIONS: Optimizing the 'MED-WELL' programme relies on an understanding of how participants interact with different entities of the programme and are motivated to attend and engage. Participants tended to favour an in-person mode of delivery, however certain advantages of delivering the programme online were also identified. The findings from this study can be used to inform similar experiential and educational exercise interventions, and may help plan for potential future restrictions on in-person educational and exercise-based programmes.

AIM: This study compared accelerometer-measured physical activity (PA) patterns in adolescents living in diverse urban and rural areas of Otago, New Zealand. METHOD: Participants (n=377; age: 14.9±1.4 years; 66.8% female; 23 schools) completed an online school travel survey, anthropometry and seven-day PA accelerometer assessment. Participants resided in large (n=237), medium (n=45) and small (n=44) urban areas or rural settings (n=51). RESULTS: Overall, participants participated in 54.4±21.0 minutes of moderate-to-vigorous physical activity (MVPA) daily and 35.0% met PA guidelines (school day vs weekend day: 40.8% vs 26.0%; p<0.001) with no difference across geographical settings. A greater proportion of males (43.2% vs 31.9%; p=0.016), school sport participants (70.1% vs 54.0%; p=0.005) and active-transport-to-school users (40.2% vs 26.1%) met PA guidelines compared to their counterparts. Compared to rural adolescents, those from large urban areas accumulated more MVPA during the school commute time (before school: 8.3±6.7 vs 5.3±3.8 minutes, p<0.001; after school: 10.1±6.0 vs 7.7±4.3 min, p=0.003), but overall spent more time sedentary (584.9±84.7 vs 527.8±88.2 minutes/day; p<0.001). CONCLUSION: PA in Otago adolescents is low, with significant differences by gender, sport participation, mode of travel to school and geographical setting. Increased PA should be encouraged in both urban and rural adolescents.

This manuscript describes the rationale and protocol of a school-based randomized controlled trial called "Cycling and Walk to School" (PACO, by its Spanish acronym) that aims to promote cycling to and from school and physical activity (PA) in adolescents. This study will examine the effects of this intervention in cycling and active commuting to and from school (ACS), PA and several ACS-related factors based on self-determination theory (SDT) and a social-ecological model (SEM). A total of 360 adolescents attending six high schools (three experimental and three control) from three Spanish cities will participate in this randomized controlled trial. The intervention (four cycling sessions; 1-2 h per session, one session per week) will be conducted by the research staff; the control group will continue their usual activities. PA levels will be measured by accelerometers, whereas ACS and the other study variables will be self-reported using questionnaires at baseline and post-intervention. The primary outcomes will be: rates of cycling to school, ACS and PA levels. In addition, SDT-related variables and individual, interpersonal, community, and environment variables relevant to ACS will be based on SEM. The findings will provide a comprehensive understanding of the short-term effects of this school-based intervention on cycling to school behaviour, ACS and PA levels in Spanish adolescents.

BACKGROUND: Despite the well-established health benefits of physical activity (PA) for young people (aged 4-19 years), most do not meet PA guidelines. Policies that support PA in schools may be promising, but their impact on PA behavior is poorly understood. The aim of this systematic review was to ascertain the level and type of evidence reported in the international scientific literature for policies within the school setting that contribute directly or indirectly to increasing PA. METHODS: This systematic review is compliant with Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines. Six databases were searched using key concepts of policy, school, evaluation, and PA. Following title and abstract screening of 2323 studies, 25 progressed to data synthesis. Methodological quality was assessed using standardized tools, and the strength of the evidence of policy impact was described based on pre-determined codes: positive, negative, inconclusive, or untested statistically. RESULTS: Evidence emerged for 9 policy areas that had a direct or indirect effect on PA within the school setting. These were whole school PA policy, physical education, sport/extracurricular PA, classroom-based PA, active breaks/recess, physical environment, shared use agreements, active school transport, and surveillance. The bulk of the evidence was significantly positive (54%), 27% was inconclusive, 9% was significantly negative, and 11% was untested (due to rounding, some numbers add to 99% or 101%). Frequency of evidence was highest in the primary setting (41%), 34% in the secondary setting, and 24% in primary/secondary combined school settings. By policy area, frequency of evidence was highest for sport/extracurricular PA (35%), 17% for physical education, and 12% for whole school PA policy, with evidence for shared use agreements between schools and local communities rarely reported (2%). Comparing relative strength of evidence, the evidence for shared use agreements, though sparse, was 100% positive, while 60% of the evidence for whole school PA policy, 59% of the evidence for sport/extracurricular PA, 57% of the evidence for physical education, 50% of the evidence for PA in classroom, and 50% of the evidence for active breaks/recess were positive. CONCLUSION: The current evidence base supports the effectiveness of PA policy actions within the school setting but cautions against a "one-size-fits-all" approach and emphasizes the need to examine policy implementation to maximize translation into practice. Greater clarity regarding terminology, measurement, and methods for evaluation of policy interventions is needed.

Despite calls in the literature, little is known about how dimensions of a social and task nature relate to each other in school and out-of-school learning environments. This study explored whether interpersonal and task dimensions of the youth sport environment, as perceived by young people, are related, and, if so, how they are related. We used data from 310 adolescent sport participants from eastern Canada (Mage = 14.69 ± 1.60 years; 54.8% girls). Participants completed comprehensive assessments of interpersonal dimensions of the sport environment and the characteristics of learning activities they do in practices. We used canonical correlation analysis to examine the multivariate shared relationship between the variable sets. The relationship was largely captured by the first three functions in the canonical model. The first two functions revealed areas of intersection between perceptions of interpersonal and practice-based activity factors in the form of supports and challenges for the learning and development process in sport. Accounting for the participants' age, the third function displayed characteristics consistent with recent descriptions of complex environments in youth sport. The findings suggest that adolescents' perceptions of interpersonal- and task-related features of sport are interdependent, and highlight the relevance of including variables assessing both factors in studies that attempt to characterize and understand learning environments in sport and other achievement domains. Findings also afford new insights into whether dimensions of a social and task nature are complementary, and inadequacies in one dimension can be attenuated by strengths in another or not.

BACKGROUND: Medical School programme workloads challenge the physical and mental health of students particularly in compressed graduate entry programmes. There is evidence that physical activity (PA) can improve holistic care and help maintain wellness among medical students. We tested the feasibility of introducing an exercise programme to the medical school curriculum which would educate and promote health and well-being among its students. METHODS: This study was conducted in a single graduate entry medical school at the University of Limerick (UL). The 'MED-WELL' programme was a six-week programme of 1 hour-long weekly sessions, each involving a different type of PA (45 min). These sessions were prefaced by an interactive lecture about how to incorporate exercise theory into daily medical practice (15 min). The study was conducted in a single graduate entry medical school at UL and involved year one and year two graduate entry medical students. Three parameters were used to test feasibility: 1. Recruitment and retention of participants, 2. Acceptability of the programme and 3. Efficacy in terms of health and well-being. The latter was assessed by administering questionnaires pre and post the intervention. The questionnaires used the following validated measurement scales: EQ-VAS; WHO-5 Well-Being Index; 3-item Loneliness Scale; Social Support Measure 3-item scale. Free text boxes also encouraged participants to discuss the merits of the programme. RESULTS: In total, 26% (74/286 students) participated in the programme. Of those who participated, 69 students (93%) attended one or more sessions of the programme and completed questionnaires at baseline and at follow-up. Significant improvements were seen in scores after the programme in the WHO-5 Well-Being Index which increased from 63.2 (95%CI: 48-78.4) to 67.5 (95%CI: 55.1-79.9); (P < 0.01), the sleep scale which increased from 3.1 (95%CI: 2.2-4.0) to 3.5 (95%CI: 2.5-4.5); (P < 0.001), and the loneliness scale which decreased from 4.1 (95%CI: 2.7-5.5) to 3.5 (95%CI: 2.5-4.5); (P < 0.005). Students level of PA during a typical week also increased from 3.7 (95%CI: 2.1-5.4) to 4.0 (95%CI, 3.5-4.5); (P < 0.05). CONCLUSION: This study has shown it is feasible to deliver this programme in a medical school's curriculum. The programme seems to be of benefit and is acceptable to students. Well-designed randomised controlled trials are needed to measure outcomes, durability of effect, and cost effectiveness.

CONTEXT: Socioeconomically disadvantaged adults have lower engagement in leisure-time physical activity than those who are more affluent. Identification of correlates of physical activity can inform the design of effective interventions. The aim of this systematic review was to identify consistent correlates of unspecified physical activity and leisure-time physical activity among socioeconomically disadvantaged adults. EVIDENCE ACQUISITION: PubMed and Scopus were searched up to May 2018, and titles/abstracts and full texts were screened against eligibility criteria. Methodologic quality was assessed, and correlates were synthesized from July to September 2018. EVIDENCE SYNTHESIS: Seventy-three studies were selected for synthesis; 48 examined unspecified physical activity and 31 examined leisure-time physical activity (6 examined both). Self-rated health, functional capacity, and physical activity self-efficacy were consistently, positively associated with unspecified physical activity. Mental health status and perceived benefits and enjoyment of physical activity were consistently, positively associated with leisure-time physical activity. Most studies were cross-sectional and used validated self-report measures of physical activity; few reported response rates >50%. CONCLUSIONS: Few factors were consistently associated with either unspecified physical activity or leisure-time physical activity. Based on available evidence, strategies to increase physical activity should consider the needs of, and focus on, those with poor self-rated health and functional capacity and should use strategies to improve physical activity self-efficacy. Strategies to increase leisure-time physical activity should focus on simultaneously addressing leisure-time physical activity and mental health concerns and improving perceptions of physical activity benefits and enjoyment. It is recommended that future studies focus on leisure-time physical activity, focus on men, use longitudinal design, examine variables related to behavioral attributes and skills, and carefully consider and plan recruitment strategies.

BACKGROUND: During a 24-h day, each given period is spent in either sedentary behaviour, sleeping, light physical activity (LPA), or moderate-to-vigorous physical activity (MVPA). In epidemiological research most studies have traditionally analysed the associations of these behaviours in isolation from each other; that is, without taking into account the displacement of time spent in the remaining behaviours. In recent years, there has been a growing interest in exploring how all the behaviours across the energy expenditure spectrum influence health outcomes. A statistical model used to investigate these associations is termed an isotemporal substitution model (ISM). Considering the increasing number of ISM-based studies conducted in all age groups, the present paper aimed to: (i) review and summarise findings from studies that employed ISM in sleep, sedentary behaviour, and physical activity research; (ii) appraise the methodological quality of the studies; and (iii) suggest future research directions in this area. METHODS: A systematic search of ten databases was performed. The Newcastle-Ottawa scale was used to assess the methodological quality of the included studies. RESULTS: Fifty-six studies met the inclusion criteria, all being of moderate or high methodological quality. Associations were reported for exchanged time varying from one minute to 120 min/day across the studies, with 30 min/day being the most common amount of time reallocated. In total, three different ISM methodologies were used. The most commonly studied health outcomes in relation to isotemporal substitutions were mortality, general health, mental health, adiposity, fitness, and cardiometabolic biomarkers. It seems that reallocations of sedentary time to LPA or MVPA are associated with significant reduction in mortality risk. Current evidence appears to consistently suggest that reductions in mortality risk are greater when time spent sedentary is replaced with higher intensities of physical activity. For adiposity, it seems that reallocating sedentary time to physical activity may be associated with reduced body mass index, body fat percentage, and waist circumference in all age groups, with the magnitude of associations being greater for higher intensities of physical activity. While there is a relatively large body of evidence reporting beneficial associations between the reallocation of time from sedentary behaviour to LPA or MVPA and cardiometabolic biomarkers among adults, there is a lack of studies among children, adolescents, and older adults. Although some studies investigated general health, mental health, and fitness outcomes, further investigation of these topics is warranted. In general, it seems that the strongest association with health outcomes is observed when time is reallocated from sedentary behaviour to MVPA. Most studies did not account for sleep time, which is a major limitation of the current evidence. CONCLUSIONS: The current evidence indicates that time reallocation between sleep, sedentary behaviour, LPA, and MVPA may be associated with a number of health outcomes. Future studies should employ longitudinal designs, take into account all movement behaviours, and examine a wider range of health, psychological, social, economic, and environmental outcomes.

BACKGROUND: People from socioeconomically disadvantaged population groups are less likely to be physically active and more likely to experience adverse health outcomes than those who are less disadvantaged. In this umbrella review we examined across all age groups, (1) the effectiveness of interventions to improve physical activity among socioeconomically disadvantaged groups, (2) the characteristics of effective interventions, and (3) directions for future research. METHODS: PubMed/MEDLINE and Scopus were searched up to May 2017 to identify systematic reviews reporting physical activity interventions in socioeconomically disadvantaged populations or sub-groups. Two authors independently conducted study screening and selection, data extraction (one author, with data checked by two others) and assessment of methodological quality using the 'Assessment of Multiple Systematic Reviews' scale. Results were synthesized narratively. RESULTS: Seventeen reviews met our inclusion criteria, with only 5 (30%) reviews being assessed as high quality. Seven (41%) reviews focused on obesity prevention and an additional four focused on multiple behavioural outcomes. For pre school children, parent-focused, group-based interventions were effective in improving physical activity. For children, school-based interventions and policies were effective; few studies focused on adolescents and those that did were generally not effective; for adults, there was mixed evidence of effectiveness but characteristics such as group-based interventions and those that focused on physical activity only were associated with effectiveness. Few studies focused on older adults. Across all ages, interventions that were more intensive tended to be more effective. Most studies reported short-term, rather than longer-term, outcomes and common methodological limitations included high probability of selection bias, low response rates, and high attrition. CONCLUSIONS: Interventions can be successful at improving physical activity among children from socioeconomically disadvantaged groups, with evidence for other age groups weak or inconclusive. More high-quality studies in this population group are needed, which adopt strategies to increase recruitment rates and reduce attrition, report longer term outcomes, and provide adequate intervention details, to allow determination of the characteristics of effective interventions. We recommend that the benefits of physical activity be recognised more broadly than obesity prevention in future studies, as this may have implications for the design and appeal of interventions.

OBJECTIVES: Healthy lifestyle habits set the stage for healthy behaviors in adulthood. We examined clustering of health behaviors (physical activity [PA], screen time, fruit and vegetable [F&V] intake) and weight status in New Zealand adolescents. METHODS: Adolescents from Dunedin, New Zealand (N = 1300; 49.0% male; 15.3±1.4 years) completed a questionnaire about PA, screen time (TV/computer/video games), and F&V intake. Height and weight were measured. A 2-step cluster analysis was completed. RESULTS: Few adolescents met individual guidelines (17.9% PA, 14.2% screen time, 29.8% F&V intake) and only 2.5% met all 3 guidelines. Weight status was 3.2%/69.6%/20.5%/6.8% for underweight/healthy weight/overweight/obese. Six clusters were identified: (1) non-adherent (not meeting any guideline) adolescents with healthy weight (38.8%); (2) non-adherent with unhealthy weight (15.4%); (3) semi-adherent (meeting some guidelines) with unhealthy weight (11.8%); (4) physically active with healthy weight (13.4%); (5) low screen time with healthy weight (7.1%); and (6) healthy F&V intake with healthy weight (13.5%). CONCLUSIONS: Few adolescents met recommended health behavior guidelines; yet, two-thirds had a healthy weight. The identified clusters had distinct sociodemographic and lifestyle characteristics. Future interventions should be comprehensive and consider socioeconomic structural factors.

OBJECTIVE: To examine the effects of a school-based intervention called Sigue la Huella (Follow the Footstep) on adolescents' daily moderate-to-vigorous physical activity (MVPA). METHOD: This quasi-experimental, cohort study took place in four secondary schools in Huesca (Spain) during the 2009-2010, 2010-2011, and 2011-2012 academic years (students aged 12-15 years). Two schools were assigned to the experimental condition (n=368) and two schools to the control condition (n=314). Sigue la Huella was based on the social ecological model and self-determination theory. MVPA was measured for 7 days on 4 occasions using accelerometers. Data were analyzed with individual growth curve models. RESULTS: There was a significant difference in linear growth rate of daily MVPA between the experimental and the control group, independent of study wave, type of school (public vs. private), grade level and gender (p<0.001). Specifically, MVPA increased in the experimental group (ß=7.02, 95% confidence interval (CI)=1.27 to 12.78, p=0.017) and tended to decrease in the control group (ß=-5.26, 95% CI=-11.17 to 0.65, p<0.081). The observed increase was larger in boys than in girls (p=0.003). CONCLUSIONS: Sigue la Huella had a positive effect on adolescents' daily MVPA over three school years. Both genders benefited from the intervention, although boys to a greater extent.

BACKGROUND: Reduced time dedicated to physical education and free play in recent decades emphasizes the need to promote opportunities for sport participation in adolescents in order to increase physical activity levels. The purpose of this study was to examine the association of sociodemographic and biological characteristics, behavioural patterns, and school-related and sport-specific variables with time spent participating in sport. METHODS: A total of 1837 secondary school students (age: 14.6 ± 1.2 years; 50.9 % boys) from 19 of 23 schools in the Otago Region (New Zealand) completed an online sport survey and Youth Physical Activity Questionnaire in 2009. Using multilevel modeling, we examined the association of individual-, school- and sport-related variables on sport participation and the amount of time spent in sports. RESULTS: Higher rates of sport participation were associated with lower neighbourhood deprivation scores (OR (95%CI): 0.75 (0.49-1.14), 0.57 (0.38-0.86), 0.48 (0.28-0.81)), higher quintiles of physical activity (2.89 (2.10-3.96), 2.81 (1.68-4.70), 3.54 (2.24-5.57), 3.97 (1.99-7.95)), highest quintiles of screen time (1.58 (0.94-2.65), 1.99 (1.42-2.80), 2.17 (1.43-3.30), 1.88 (1.37-2.57)) and boys only school status (2.21 (1.57-3.10)). Greater amount of time spent in sports was associated with male gender (0.56 (0.43-0.74), lower neighbourhood deprivation scores (0.72 (0.59-0.93), 0.78 (0.58-1.04), 0.62 (0.39-1.00)), higher quintiles of physical activity (3.18 (2.29-4.41), 4.25 (2.91-6.20), 8.33 (5.58-12.44), 6.58 (4.07-10.64)), highest quintile of screen time (1.83 (1.31-2.56), greater availability of sports outside school (1.68 (1.22-2.32)), better sport management (2.57 (1.63-4.07)) and provision of sport courts at school (0.57 (0.40-0.81)). Conversely, obesity was associated with less time spent participating in sport (0.50 (0.31-0.80)). CONCLUSION: Results support the use of sport participation as an effective strategy to increase physical activity levels and identify target groups and areas for interventions, program design and policy development. Interventions should focus on improving accessibility to sport programs for all adolescents, providing adequate sport grounds at school, and promoting good sport management practices. Programs and policies encouraging sport participation should address in particular the needs of adolescents living in deprived neighborhoods, those attending coeducational and girls-only schools, and those who are obese.

BACKGROUND: While the importance of individual and school factors as correlates of overall youth physical activity has been demonstrated by previous research, less is known about the relationship of these factors with specific patterns of physical activity during adolescence. Thus, the purpose of this study was to examine the association of selected individual and school factors with patterns of physical activity based on a sum index of physical activity in a population-based sample of Spanish adolescents. METHODS: One thousand and eighty-four students aged 12 to 17 years completed a self-report survey once during school hours. In addition to participation in physical activity outside of school hours, the following variables were included in the analysis: gender, age, weight status, physical self-perceptions, evaluation of the school physical education experience, and type of school (public vs private). Multinomial logistic regression was used to model the associations among the variables and to calculate odd ratios (ORs) and 95% confidence intervals (CIs) for each pattern of physical activity. RESULTS: The physical self-perceptions variable was the most consistent individual correlate of physical activity across participation patterns (ORs ranging from 4.29 to 1.88, CIs ranging from 2.16-8.54 to 1.10-3.21). Regarding the school variables included in this study, both were linked with participation in physical activity, but evaluation of the physical education experience showed the most consistent associations across activity patterns (ORs 2.49-2.17, CIs 1.49-4.15 to 1.25-3.74). CONCLUSION: Physical education programs may benefit adolescents with different physical activity participation preferences regardless of important individual characteristics and broader school factors.
