We investigated the longitudinal associations between sports participation patterns in youth and physical activity (PA) in adulthood. PA was self-reported triannually between ages 9–18 (n = 2550, 52% females) and measured by accelerometers in mid-adulthood (n = 1002, 61% females, aged 48 ± 4 years). Three latent classes of youth sports participation emerged for both genders: 1) "organized sports" (persistent high PA with regular sports club activities), 2) "unorganized sports" (persistent high PA without sports club activities and 3) "low activity" (low PA with decreasing sports involvement). These groups comprised 29%, 34% and 37% of males, and 23%, 27% and 50% of females, respectively. Youth "organized sports" was associated with higher adult PA in both males (+1166 steps/day, p = 0.012) and females (+15 min/day moderate-to-vigorous PA [MVPA], +1064 steps/day, +1066 leisure-time steps/day; p ≤ 0.005) compared to "low activity". In males, youth "organized sports" was associated with higher adult PA (+1103 steps/day, −26 min/day sedentary time and +133 counts/minute higher total PA, p ≤ 0.039) compared to "unorganized sports". In females, "unorganized sports" in youth was related to higher adult PA (+10 min/day MVPA, p = 0.034) when compared to "low activity". Sustained participation in youth organized sports, and for females, also in unorganized sports, is positively linked with adult PA. [ABSTRACT FROM AUTHOR]

Abstract Background It is a common belief that most sports clubs and organisations are primarily focused on elite sports while placing less emphasis on the promotion of health-enhancing physical activity (HEPA). However, there is a lack of evidence on this topic in the scientific literature. Therefore, the aim of this study was to determine the level and correlates of the commitment of sports organisations in Europe to HEPA promotion. Methods Representatives of 536 sports organisations from 36 European countries responded to our survey. A multiple regression analysis was conducted with the commitment of sports organisation to HEPA promotion (0 [“not at all”] – 10 [“most highly”]) as the outcome variable and organisation type (“national sport association” reference group [ref], “European sports federation”, “national umbrella sports organisation”, “national Olympic committee”, “national sport-for-all organisation”), headquarters in a European Union member state (“no” [ref], “yes”), region of Europe (“Western” [ref], “Central and Eastern”, “Northern”, “Southern”), commitment to elite sports (“low” [ref], “medium”, “high”), and awareness of Sports Club for Health (SCforH) guidelines (“no” [ref], “yes”) as explanatory variables. Results Approximately 75.2% (95% confidence interval [CI]: 71.5, 78.8) of sports organisations were highly committed to elite sports. Only 28.2% (95% CI: 24.4, 32.0) of sports organisations reported a high commitment to HEPA promotion. A higher commitment to HEPA promotion was associated with the national Olympic committees (β = 1.48 [95% CI: 0.41, 2.55], p = 0.007), national sport-for-all organisations (β = 1.68 [95% CI: 0.74, 2.62], p

The study was undertaken to explore the experiences of older adults and service providers in a settings-based health promotion initiative in a football club. We conducted semi-structured interviews with 10 older adults attending an 'Extra Time Hub' (ETH) and two staff delivering the initiative. Our reflexive thematic analysis generated six themes. Findings revealed the brand of the sports club attracted some to join the ETH, but through partnerships with local agencies, the initiative was also successful in widening participation beyond older adults with an interest in football. Participants perceived that the ETH was beneficial for their mental health, helped them develop social connections, and promoted positive physical activity experiences. Moreover, the variety of pleasures derived from participation were also discussed. Our findings also illustrate the central role of staff in older adults' experiences of this form of health promotion. Overall, this study contributes to understandings of settings-based health promotion activities in sports clubs, and also demonstrates the potential for sports clubs to widen engagement with the local community through health promotion for older adults.

Methods: Representatives of 536 sports organisations from 36 European countries responded to our survey. A multiple regression analysis was conducted with the commitment of sports organisation to HEPA promotion (0 ["not at all"] – 10 ["most highly"]) as the outcome variable and organisation type ("national sport association" reference group [ref], "European sports federation", "national umbrella sports organisation", "national Olympic committee", "national sport-for-all organisation"), headquarters in a European Union member state ("no" [ref], "yes"), region of Europe ("Western" [ref], "Central and Eastern", "Northern", "Southern"), commitment to elite sports ("low" [ref], "medium", "high"), and awareness of Sports Club for Health (SCforH) guidelines ("no" [ref], "yes") as explanatory variables. Results: Approximately 75.2% (95% confidence interval [CI]: 71.5, 78.8) of sports organisations were highly committed to elite sports. Only 28.2% (95% CI: 24.4, 32.0) of sports organisations reported a high commitment to HEPA promotion.

Conclusion: From our findings, it seems that most sports organisations are primarily focused on elite sports. Coordinated actions at the European Union and national levels are needed to improve the promotion of HEPA through sports organisations. In this endeavour, it may be useful to consider national Olympic committees, national sport-for-all organisations, and relevant sports organisations in Central and Eastern Europe as role models and to raise the awareness of SCforH guidelines.

Background: The contribution of sports related factors to predicting long-term physical activity (PA) are unclear. The purpose of this study is to examine tracking of PA during key transition periods in youth and to determine the longitudinal associations between sports club participation and PA. Methods: Participants (n = 873, baseline age 10 to 18 years) completed self-report surveys in 2009 and 2014 that included the PACE+ PA tool and sports club participation questions. Spearman correlations assessed PA tracking. ANCOVA analyses examined predictors (sports participation at baseline) of PA (follow-up), adjusting for (a) age and sex; and (b) age, sex, and baseline PA. Results: Tracking of PA was weak-to-moderate (ρ = .16 to .47). Greater sports participation frequency at baseline significantly predicted PA at follow-up (P < .01). Involvement in club sports at an elite level had a medium-to-large effect on PA levels 5 years later [d = .75 adjusting for (a); d = .60 adjusting for (b)]. Conclusion: PA should be promoted in youth as tracking coefficients suggest it can, to an extent, continue into later life. The standard achieved in sport has a role in predicting later PA. PA promotion strategies should include frequent, high quality opportunities for sports participation. [ABSTRACT FROM AUTHOR]

Background: Little is known about the relationship between physical activity and health-related quality of life (HRQOL) in adolescents. The purpose of this study was 1) to quantify the predictive power of greater physical activity on higher HRQOL in adolescents and 2) to analyze whether the prediction is better for the sports club setting than for the leisure time setting. Methods: Within the framework of the German Health Interview and Examination Survey for Children and Adolescents and the "Motorik-Modul," 1828 German adolescents aged 11-17 years completed a questionnaire concerning the amount of weekly physical activity at school, in sports clubs, and during leisure time. The KINDL-R questionnaire was used to assess HRQOL. Linear and multiple regression analyses were used to analyze the effects of physical activity on HRQOL. Results: In regression analyses controlling for sociostructural variables, greater general physical activity was a significant predictor of higher HRQOL (P < .001). While greater physical activity in sports clubs significantly predicted higher HRQOL, greater physical activity during leisure time predicted higher HRQOL only to a certain level. Overall, the level of explained variance was low. Conclusions: Being physically active especially in sports clubs is positively linked to higher HRQOL of adolescents. [ABSTRACT FROM AUTHOR]

Background: Lifestyle interventions to prevent paediatric obesity often target family and peer settings; their success is likely to depend on the influence that peers and families exert on children's lifestyle behaviors at different developmental stages. Objective: First, to determine whether children's lifestyle behavior more closely resembles their peers' or siblings' behaviors. Secondly, to investigate longitudinally whether children's behavioral change is predicted by that of their peers or their siblings as they grow older. Methods: The European prospective IDEFICS/I.Family cohort (baseline survey: 2007/2008, first follow-up: 2009/2010, and second follow-up: 2013/2014) aims at investigating risk factors for overweight and related behaviors during childhood and adolescence. The present investigation includes 2694 observations of children and their siblings aged 2 to 18 years. Peers were defined as same-sex, same-age children in the same community and identified from the full cohort. The longitudinal analysis (mean follow-up time: 3.7 years) includes 525 sibling pairs. Children's lifestyle behaviors including fast food consumption (frequency/week), screen time (hours/week) and sports club participation (hours/week) were assessed by questionnaire. Data were analyzed using multilevel linear models. Results: Children's lifestyle behavior was associated with the respective behavior of their peers and sibling for all 3 behaviors. For fast food consumption, the peer resemblance was more than 6-fold higher than the sibling resemblance and the peer resemblance surpassed the sibling resemblance by the age of 9–10 years. The similarities with peers for fast food consumption and screen time steadily increased, while the similarities with siblings steadily decreased with increasing age of the children (Pinteraction < 0.001). In contrast, the relative importance of peers and siblings on sports club duration did not vary by the age of the children. Longitudinal results showed that children's changes in fast food consumption were more strongly associated with those in their peer group than their sibling, in particular if the age gap between siblings was large. Conclusion: In conclusion, our results support the implementation of multi-setting interventions for improving lifestyle behaviors in children. Our findings might also guide future intervention studies in the choice of timing and setting in which interventions are likely to be most effective. From the ages of 9–10 years onwards, family- or home-based interventions targeting children's fast food intake and screen time behavior may become less effective than school- or community-based interventions aimed at peer groups.

Aims: Insufficient physical activity (PA) is one of the largest public health challenges of our time and requires a multisectoral public-health response. PA recommendations state that all children and adolescents should accumulate at least 60 minutes of moderate-to-vigorous PA (MVPA) daily and carry out vigorous PA (VPA) three times weekly. While participation in sports club activities is known to enhance the probability of reaching the recommended overall PA level, less is known about the contribution of sports club participation to VPA, and few cross-national comparisons have been carried out. The purpose of this paper is to study whether participation in sports club activities is associated with meeting the overall PA and VPA recommendations among children and adolescents across six European countries, namely Belgium (Flanders), Czech Republic, Finland, France, Ireland and Sweden. Methods: Analyses were carried out on existing self-reported national data sets using descriptive statistics and logistic regression. Results: Results indicate that approximately two-thirds of children and adolescents take part in sports club activities in the given countries. Sports club participants were more likely to meet the overall PA recommendations (OR 2.4–6.4) and VPA recommendation (OR 2.8–5.0) than non-participants. Conclusions: The extent to which overall PA and/or VPA is gained through sports club participation versus other settings needs to be further studied. Nonetheless, it can be argued that sports clubs have an important position in PA promotion for younger populations. [ABSTRACT FROM AUTHOR]

Aims: The aim of this research was to compare the levels of perceived health literacy among adolescents who do or do not participate in sports club activities. Organized sport club activities reach a high proportion of adolescents, and have the potential to contribute to the development of their health literacy. Methods: The cross-sectional data on health literacy among school children in Finland (aged 13 and 15, n=3852) were measured, as a part of the Health Behaviour in School-Aged Children (HBSC) study, using the Health Literacy for School-aged Children (HLSAC) instrument. Sports club participation and its association with health literacy were examined in relation to age, gender, family affluence, school achievement, and physical activity. The statistical analyses included cross-tabulation and the multilevel mixed-effects logistic regression analyses. Results: Perceived health literacy was higher among adolescents who participated in sports club activities. This conclusion was valid for boys and girls, for both age groups, among those who were physically active 6–7 days a week, had at least moderate school achievement, and those who belonged to the middle or high affluence families. From the health literacy perspective, participation in sports club activities was especially beneficial for those having low or moderate school achievement level. Conclusions: The sports club setting may work towards equalizing health literacy differences related to school achievement. However, the clubs should ensure that access is available to as many adolescents as possible; by this means they may spread beneficial influences, supporting the development of health literacy among broader population groups.

Background: The sports club is seen as a new relevant setting to promote health-enhancing physical activity (HEPA) among inactive population groups. Little is known about the effectiveness of strategies and activities implemented in the sports club setting on increasing HEPA levels. This study investigated the effects of Start2Bike, a six-week training program for inactive adults and adult novice cyclers, on HEPA levels of participants in the Netherlands.Methods: To measure physical activity, the Short QUestionnaire to ASsess Health-enhancing physical activity was used (SQUASH). Start2Bike participants were measured at baseline, six weeks and six months. A matched control group was measured at baseline and six months. The main outcome measure was whether participants met the Dutch Norm for Health-enhancing Physical Activity (DNHPA: 30 min of moderate-intensity activity on five days a week); Fit-norm (20 min of vigorous-intensity activity on three days a week); and Combi-norm (meeting the DNHPA and/or Fit-norm). Other outcome measures included: total minutes of physical activity per week; and minutes of physical activity per week per domain and intensity category. Statistical analyses consisted of McNemar tests and paired t-tests (within-group changes); and multiple logistic and linear regression analyses (between-group changes).Results: In the Start2Bike group, compliance with Dutch physical activity norms increased significantly, both after six weeks and six months. Control group members did not alter their physical activity behavior. Between-group analyses showed that participants in the Start2Bike group were more likely to meet the Fit-norm at the six-month measurement compared to the control group (odds ratio = 2.5; 95% confidence interval (CI) = 1.1-5.8, p = 0.03). This was due to the Start2Bike participants spending on average 193 min/week more in vigorous-intensity activities (b = 193; 95% CI = 94-293, p < 0.001) and 130 min/week more in sports activities (b = 130; 95% CI = 82-178, p < 0.001) than control group members.Conclusions: Start2Bike positively influences HEPA levels of participants by increasing participation in sport. A relatively short sporting program, offered by a sports club, can be used to encourage less active people to engage in and continue sport at HEPA levels. Overall, sport can contribute to health through increased HEPA and the sports club can serve as a setting to stimulate this. [ABSTRACT FROM AUTHOR]

Young people with disabilities participate in sports to a lesser extent than other adolescents. That physical activity has positive effects on young people are understood. Sports clubs are identified as potential environments for physical activity. The reasons why young people with disabilities participate to a lower extent in organized sport is complex and barriers can be deriving from many different levels. However, barriers have been studied more than what can facilitate participation in organized sport. There for the aim of this study is to increase the understanding of how sports clubs include children and adolescents with disabilities in their activities. The results of this systematic search are presented using the three research questions: What are the characteristics of the sports clubs that include young people with disabilities?; How are the young people with disabilities included in sports clubs' activities?; and finally Why are young people with disabilities included in the sports activities?. A vision must be to go from adapting physical activity for disabled persons to adapting physical activity for all people, because the diversity of people's reasons for doing sports, their differing backgrounds and their uniqueness all demand it. This will result in more people doing sports for longer in life. [ABSTRACT FROM AUTHOR]

Background: Many students leave compulsory school without being qualified to apply for national upper secondary school programmes. Despite efforts, the number of unqualified students in Sweden has increased. Grades from compulsory school have direct implications for students' educational futures and the requirement to qualify for an upper secondary school programme is at least the grade G (pass), in the subjects Swedisb/Swedish as a second language, Mathematics, and English. Earlier research shows that the amount of physical activity, students' motor skills, and grades in Physical Education can have an impact on school achievements, but no study has examined the relationships of these factors in this particular group of students. Purpose: The aim was to study relationships between physical activity and school performance among Swedish compulsory school students who fail to achieve sufficient grades to move on to upper secondary school (about one in five students in the city of Malmö). Method: The population consisted of389 students of which 76% (147 male, and 146 female) participated in a web inquiry. For statistical analyses of the responses, the Statistical Package for the Social Sciences program was used. Non-parametric tests (Chi-squared, Kruskal-Wallis, and Mann-Whitney) were used to study differences between groups, and Spearman's rank correlation and Pearson's product moment correlation were used for correlation analyses. Findings: The results show that less than 50% were physically active in the school subject physical education and health (PEH), and 14% never participated. Forty-five per cent were never physically active during their spare time. Twenty-nine per cent failed to reach the goals in PEFL Nine per cent (14% of boys, and 4% of girls), received the highest grade in PEH: pass with special distinction. Significant correlations were found between the level of physical activity and grade in PEH, as well as between physical activity and total grades. Grades in PEH correlated with grades in Swedish, Mathematics, and English. Students who responded that they skipped lessons once a week or more, had significantly lower grades in PEH and in total than students who never or less often skipped school lessons. Students who had good self-esteem (n = 162) were significantly more physically active than those who had low self-esteem (n = 32). Their answers to the question, 'How physically active were you during school year nine?' showed that they moved and became breathless and sweaty more than students who had lower self-esteem. They also did sports/ exercise significantly more both in and outside of sports clubs. Conclusion: The findings of the relatively low levels of physical activity and the significant correlation between physical activity and school performance indicate the importance of examining how schools can improve students' self-esteem and motivation to be physically active and participate in PEH and other lessons.

This paper explores the efficacy and value of sports clubs as a setting for health promotion. Sports clubs for children and adolescents are the primary focus of the paper, and the aims are two-fold. Aims: Firstly, the paper aims to review the basis for and elements of the health promoting sports club (HPSC) concept. Secondly, the aim is to overview the international evolution of the HPSC concept and its usefulness in the research. The settings-based health promotion approach forms the basis for the HPSC concept and it is introduced first. Thereafter, both obligating and prospecting factors, to justify the importance for sports clubs to address health promotion, are expressed. Major prospecting factors relate to the facts that sports club activities reach a lot of children and adolescents, and that its educational nature is informal due to voluntary participation. The paper also presents multilevel structure of sports clubs, as well as the determinants affecting the settings-based work. The research concerning health promotion in sports-related settings is evolving worldwide, and Nordic countries are in the front line of this new-wave of settings-based health promotion. Indeed, it has been claimed that, for the settings approach to assimilate to current societal challenges, there is a need to widen the reach of the approach to non-traditional, non-institutional settings, like sports clubs.

Background The prevalence of male obesity is increasing, but men are less likely than women to attend existing weight management programmes. We have taken a novel approach to reducing perceived barriers to weight loss for men by using professional football (soccer) clubs to encourage participation in a weight management group programme, gender-sensitised in content and style of delivery. Football Fans in Training (FFIT) provides 12 weeks of weight loss, physical activity and healthy eating advice at top professional football clubs in Scotland. This pilot randomized trial explored the feasibility of using these clubs as a setting for a randomized controlled trial of 12 month weight loss following men's participation in FFIT. Methods A two-arm pilot trial at two Scottish Premier League football clubs (one large, one smaller), with 103 men (aged 35-65, body mass index (BMI) ≥27 kg/m2) individually randomized to the intervention (n=51, received the pilot programme (p-FFIT) immediately) and waitlist comparison (n=52, received p-FFIT after four months) groups. Feasibility of recruitment, randomization, data collection and retention were assessed. Objective physical measurements (weight, waist circumference, blood pressure, body composition) and questionnaires (self-reported physical activity, diet, alcohol consumption, psychological outcomes) were obtained from both groups by fieldworkers trained to standard protocols at baseline and 12 weeks, and from the intervention group at 6 and 12 months. Qualitative methods elicited men's experiences of participation in the pilot trial. Results Following a short recruitment period, the recruitment target was achieved at the large, but not smaller, club. Participants' mean age was 47.1±8.4 years; mean BMI 34.5±5.0 kg/m2. Retention through the trial was good (>80% at 12 weeks and 6 months; >75% at 12 months), and 76% attended at least 80% of available programme delivery sessions. At 12 weeks, the intervention group lost significantly more weight than the comparison group (4.6% c.f.--0.6%, p<.001) and many maintained this to 12 months (intervention group baseline-12 month weight loss: 3.5%, p<.001). There were also improvements in self-reported physical activity and diet, many sustained long term. Conclusions The results demonstrated the feasibility of trial procedures and the potential of FFIT to engage men in sustained weight loss and positive lifestyle change. They supported the conduct of a fully-powered randomized controlled trial. [ABSTRACT FROM AUTHOR]

Abstract Background This study analyses the effect of active participation in a sports club, physical activity and social networks on the development of lung cancer in patients who smoke. Our hypothesis is that study participants who lack social networks and do not actively participate in a sports club are at a greater risk for lung cancer than those who do. Methods Data for the study were taken from the Cologne Smoking Study (CoSmoS), a retrospective case-control study examining potential psychosocial risk factors for the development of lung cancer. Our sample consisted of n = 158 participants who had suffered lung cancer (diagnosis in the patient document) and n = 144 control group participants. Both groups had a history of smoking. Data on social networks were collected by asking participants whether they participated in a sports club and about the number of friends and relatives in their social environment. In addition, sociodemographic data (gender, age, education, marital status, residence and religion), physical activity and data on pack years (the cumulative number of cigarettes smoked by an individual, calculated by multiplying the number of cigarettes smoked per day by the number of years the person has smoked divided by 20) were collected to control for potential confounders. Logistic regression was used for the statistical analysis. Results The results reveal that participants who are physically active are at a lower risk of lung cancer than those who are not (adjusted OR = 0.53*; CI = 0.29-0.97). Older age and lower education seem also to be risk factors for the development of lung cancer. The extent of smoking, furthermore, measured by pack years is statistically significant. Active participation in a sports club, number of friends and relatives had no statistically significant influence on the development of the cancer. Conclusions The results of the study suggest that there is a lower risk for physically active participants to develop lung cancer. In the study sample, physical activity seemed to have a greater protective effect than participation in a sports club or social network of friends and relatives. Further studies have to investigate in more detail physical activity and other club participations.

The purpose of this study was to examine parental influences on children's participation in sport and their later physical activity The population for the study consisted of a random sample of 1881 9- to 15-year-old boys and girls who were exposed to the extensive research program called "Cardiovascular Risk in Young Thins" in 1980. They and their parents have been followed up for twelve years at three-year intervals by means of a short questionnaire concerning physical activity and other factors. The results indicated that the fathers' physical activity in 1980 was related to their children's habitual physical activity in the same year, and gave in boys and girls a significant prediction of PA! values twelve years later when the starting point was the age of 9, and also among boys from 15 years of age to 27. During the three years follow-up period, the extent of participation in sport was higher in families with active parents than in families with passive parents and single parents. The relationship of physical activity and sports participation with fathers' socioeconomic status and education was not so strong as with fathers' physical activity. [ABSTRACT FROM AUTHOR]

Background: The organized sports sector has received increased interest as a setting to stimulate physical activity among inactive target groups. To include many inactive people and to obtain population health benefits, it is important that effective sporting programs are sustained (i.e. continuation of program activities) over a long period of time. This study identified the factors influencing the long-term sustainability of these kind of sporting programs located within local sports clubs in the Netherlands. Methods: Fourteen Dutch sporting programs aimed at increasing physical activity levels of inactive population groups and funded within the National Action Plan for Sport and Exercise (NAPSE) were the focus of this study. The programs were developed by ten Dutch National Sports Federations (NSFs) and implemented by different sports clubs in the Netherlands within a three-year funded implementation period (2008–2011). This research consisted of semi-structured face-to-face interviews with the program coordinators of the NSFs (n = 14) and semi-structured telephone interviews with representatives of sports clubs that provided the programs (n = 17 continued the program, n = 11 discontinued the program) six and a half years after the funding period ended (November 2017–March 2018). A sustainability framework with five pre-specified main themes (i.e. program design, implementation, trainer/coach, organizational setting, broader community environment) guided data collection and (deductive) thematic analysis. Results: Ten of the fourteen NAPSE funded sporting programs were sustained at the level of the NSFs. Most factors facilitating (+) and impeding (−) the long-term sustainability of the programs were common to both NSFs and sports clubs, like program adaptation (+) and a lack of program financing (−). Program evaluation (+) and high program costs (−) were specific factors mentioned by NSFs, while factors related to human resources (e.g. lack of volunteers (−)) or the sports club nature (e.g. social aspect in program design (+)) applied to sports clubs. The factors were summarized in the form of a checklist. Conclusions: Key factors influencing the long-term sustainability of the sporting programs were identified. The results can be used to develop strategies to promote long-term sustainability of these kind of programs and inform funding guidelines in countries with a similar organized sports infrastructure.

Background: Health-enhancing physical activity (HEPA) promotion programs are implemented in sports clubs. The purpose of this study was to examine the characteristics of the insufficiently active participants that benefit from these programs.Methods: Data of three sporting programs, developed for insufficiently active adults, were used for this study. These sporting programs were implemented in different sports clubs in the Netherlands. Participants completed an online questionnaire at baseline and after six months (n = 458). Of this sample, 35.1% (n = 161) was insufficiently active (i.e. not meeting HEPA levels) at baseline. Accordingly, two groups were compared: participants who were insufficiently active at baseline, but increased their physical activity to HEPA levels after six months (activated group, n = 86) versus participants who were insufficiently active both at baseline and after six months (non-activated group, n = 75). Potential associated characteristics (demographic, social, sport history, physical activity) were included as independent variables in bivariate and multivariate logistic regression analyses.Results: The percentage of active participants increased significantly from baseline to six months (from 64.9 to 76.9%, p < 0.05). The bivariate logistic regression analyses showed that participants in the activated group were more likely to receive support from family members with regard to their sport participation (62.8% vs. 42.7%, p = 0.02) and spent more time in moderate-intensity physical activity (128 ± 191 min/week vs. 70 ± 106 min/week, p = 0.02) at baseline compared with participants in the non-activated group. These results were confirmed in the multivariate logistic regression analyses: when receiving support from most family members, there is a 216% increase in the odds of being in the activated group (OR = 2.155; 95% CI: 1.118-4.154, p = 0.02) and for each additional 1 min/week spent in moderate-intensity physical activity, the odds increases with 0.3% (OR = 1.003; 95% CI: 1.001-1.006, p = 0.02).Conclusions: The results suggest that HEPA sporting programs can be used to increase HEPA levels of insufficiently active people, but it seems a challenge to reach the least active ones. It is important that promotional strategies and channels are tailored to the target group. Furthermore, strategies that promote family support may enhance the impact of the programs.
