Abstract
Abstract
Background
Insufficient physical activity (PA) is a risk factor for obesity and non-communicable diseases and seems more prevalent among socioeconomically disadvantaged (SED) adults. Recreational walking (RW) is an important type of leisure time PA which can be done for free and without specific equipment or facilities. Environmental factors influencing PA may be particularly important for SED adults who are more reliant on their direct environment. The objectively measured environment is not always congruent with the perception of residents, and this may differ by socioeconomic group. This study aims to identify the local environmental factors important for RW as perceived by SED adults.
Methods
This study is part of the CIVISANO project. Purposeful convenience sampling was used to recruit 38 SED adults (25-65 y/o) in two Flemish semi-urban municipalities. Individual walk-along interviews have been performed in the participants’ neighborhood. 20 participants joined the focus group discussion (n = 4) that were intended for member checking, to categorize identified environmental factors and to identify local actions to promote recreational walking. MaxQDA was used for content analysis.
Results
The way the environment is perceived by SED adults plays an important role in their RW behavior. Results demonstrate the interrelation of different environmental types (physical, sociocultural, economic, political and information) and sizes (micro, meso, macro). Improving communication and knowledge transfer, stimulation of physical, sociocultural, and economic accessibility, and promotion of physical and social safety are identified most important action points for the local government to facilitate RW.
Conclusions
Our findings indicate that the perceived local environment can play an important role in promoting RW among SED adults. Future studies should investigate if changes in these environments and in residents’ perception lead to changes in RW behavior of SED adults.

Abstract
Abstract
Background
Health inequalities partially remain due to differences in diet between socioeconomic groups. Examining the association between socio-ecological factors and the diet of socioeconomically disadvantaged (SED) individuals can enhance the development of interventions to decrease health inequalities.
Methods
In total, 278 SED adults residing in two Flemish municipalities completed a survey addressing sociodemographics, diet, health and their perceptions of the food environment. The objective food environment was examined by assessing food retailer information in street network-based buffers of 500m and 1000m around participants’ addresses. Linear regression was used to test assumptions.
Results
Individual factors such as poor subjective health (OR0.58;CI 0.34-0.97), food insecurity (OR0.60;CI 0.38-0.94) and living alone (OR0.86;CI 0.75-0.98) were negatively associated with healthy dietary habits such as daily fruit and vegetable (FV) consumption. Positive perceptions on the availability of FV were positively associated (OR1.09;CI 1.02-1.17) with daily FV consumption. Objective food environmental factors showed a stronger association with unhealthy dietary habits. A greater amount of retailers within 1000m walking distance was negatively associated with fast-food (OR0.96;CI 0.94-0.99) and sugar-sweetened beverages (SSB) consumption (OR0.93; CI 0.88-0.98). More supermarkets within 500m distance was negatively associated (OR0.77;CI 0.58-0.97) with SSB consumption, while more convenience stores within a 1000m distance was positively associated (OR1.48;CI 1.17-1.88) with SSB consumption.
Conclusions
Our findings suggest that factors associated with the diet of SED adults differ according to food and drink items. Interventions focused on this population should take these differences into account.

Abstract
Abstract
Background
The prevalence of obesity worldwide has been steadily increasing. This has generated an uptake in research determining the cause of obesity. One of the primary drivers that have been identified is the “obesogenic environment', which is an environment that contains features that increase excess weight in individuals or populations. Obesogenic environments are unevenly distributed with socio-economically disadvantaged neighbourhoods being more affected.
Methods
This survey is part of the CIVISANO (‘Community-based participatory research to tackle the disparities in health-enhancing lifestyle within the municipality environment') project, which will be conducted in two municipalities. Respondents will be socio-economically disadvantaged adults between 25- and 65-years old. To gain information on individual characteristics and perceptions of the obesogenic environment, residents will be invited to complete a survey. Since it is known that socio-economically disadvantaged respondents are difficult to reach a non-random active recruitment approach will be applied. The following variables are included in the survey: sociodemographic information, subjective health and anthropometrics, dietary habits, food security and physical activity. Items from the SPOTLIGHT project survey and NEMS-P survey were added to assess respondent's perceptions of features of the obesogenic environment. Additional variables on individual characteristics were based on items from the Belgian National Health Interview Survey of 2019.
Results
Through the survey, we expect to gain insight into the perceptions of socio-economically disadvantaged adults on obesogenic features of their local environment. Initial results from the survey will be available in the upcoming months.
Conclusions
The construction of instruments to assess the context-specific features, which can be compared with objective measurements, can increase our knowledge of contextual determinants of the obesogenic environment.
Key messages
The first Flemish survey that focuses on perceptions of socio-economically disadvantaged adults on obesogenic features of their local environment in the municipal context. Gaining a better understanding of the local obesogenic environment creates an opportunity to promote and strengthen the development of effective local interventions to build healthier environments.

Abstract
Abstract
Background
Adolescents' sleep behavior has deteriorated over the last decades. However, little research has been conducted into possible psychosocial factors related to this behavior, which is an important prerequisite to develop effective sleep behavior interventions. In addition, previous research showed that actively involving adolescents in the development of interventions increases the chance of effectivity and sustainability. This study examined psychosocial factors related to sleep behavior in adolescents and investigated adolescents' willingness to participate in the development of a sleep behavior intervention.
Methods
Nine focus group interviews were conducted with seventy-two students (63,9% girls, 14.8 (±1.0) years) using a standardized interview guide. Interviews were audio-recorded and thematic content analysis was performed using Nvivo 11.
Results
Adolescents had adequate knowledge of sleep hygiene and short-term consequences of sleep deficiency, but limited knowledge of sleep norms and long-term consequences. Positive attitudes towards sleep were outweighed by positive attitudes towards other behaviours such as screen time. Leisure activities, smartphones, television, schoolwork, early school time and worrying were mentioned as barriers for healthy sleep. Adolescents showed low self-efficacy towards changing their sleep behaviors and perceived a negative social norm towards sleep. Although some adolescents indicated parental rules to have a positive influence on their sleep, others indicated these sometimes provoked frustration. Finally, adolescents emphasized the importance of their participation in the development of a sleep behavior intervention at school, although adult guiding would be needed.
Conclusions
Future interventions promoting heathy sleep in adolescents could focus on psychosocial factors such as knowledge, attitudes, barriers, self-efficacy and social perceived norm and could involve adolescents in intervention development.
Key messages
Future interventions promoting heathy sleep in adolescents should in addition to knowledge, also focus on psychosocial factors such as attitudes, self-efficacy and perceived social norms. Adolescents emphasize the importance of their participation in the development of a sleep behavior intervention. This approach could be worth trying in future research.

Association of alcohol control policies with adolescent alcohol consumption and with social inequality in adolescent alcohol consumption: A multilevel study in 33 countries and regions. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2020; 84:102854. [PMID: 32717703 PMCID: PMC7762782 DOI: 10.1016/j.drugpo.2020.102854] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2020] [Revised: 06/28/2020] [Accepted: 07/03/2020] [Indexed: 10/26/2022]
Abstract
Background Previous research found inconsistent associations between alcohol control policies and socioeconomic inequality with adolescent drinking outcomes. This study expands the focus beyond individual associations to examine whether a combination of policies is related to socioeconomic inequality in adolescent drinking outcomes and whether this relationship varies across survey years. Methods Multilevel modelling of 4 waves of repeat cross-sectional survey data (2001/02, 2005/06, 2009/10, and 2013/14) from the Health Behaviour in School-aged Children (HBSC) study was carried out. The sample was composed of 671,084 adolescents (51% girls) aged 11, 13, and 15 (mean age=13.58; SD=1.65) from 33 European and North American countries/regions. The dependent variables were lifetime alcohol consumption, weekly alcohol consumption, and lifetime drunkenness. Independent variables were of three types: individual-level variables (age, sex, Family Affluence Scale, and the Perceived Family Wealth), time-level variable (survey year), and context-level variables (minimum legal drinking age, physical availability, advertising restrictions, a total alcohol policy index, and affordability of alcohol). Results The total alcohol policy index showed a negative relationship with both lifetime and weekly consumption. Higher affordability of alcohol was related to higher lifetime and weekly consumption and higher lifetime drunkenness. Family Affluence Scale was positively related to all three alcohol measures and Perceived Family Wealth was negatively related to lifetime drunkenness, with these associations increasing across survey years. The total alcohol policy index buffered the associations of Family Affluence Scale and Perceived Family Wealth with adolescent drinking outcomes. Conclusion A combination of alcohol control policies is more effective in reducing adolescent drinking outcomes than single policy measures. Reducing the affordability of alcohol stood out as the most successful single measure. Socioeconomic inequalities (i.e. higher alcohol consumption and drunkenness in adolescents with higher family affluence and higher drunkenness in adolescents perceiving their families to be poor) have persisted and even increased across survey years. A combined alcohol control policy can help in tackling them.

Abstract
Abstract
Background
culture is believed to have an important impact on health and health inequalities and this may vary between countries. Empirical data are however scarce, especially in adolescent populations. We examined the impact of cultural values (emancipatory values index) on cross-national variations in adolescent health, health inequalities and evolutions in these inequalities.
Methods
individual-level data from 21 countries participating in the 2002/2006/2010/2014 waves of the Health Behaviour in School-aged Children (HBSC) study were combined with country-level data from the World Values Longitudinal Dataset (n = 416777). Multilevel linear and logistic regression analyses were performed accounting for the hierarchical data structure (individual, country-year and country level).
Results
cultural value differences between countries were weakly related to adolescents’ health and health behaviour but had a profound impact on the magnitude of inequalities. In countries characterised by a high level of emancipatory values, material (family affluence-based) inequalities in both health and health behaviours tended to be lower whereas non-material (occupational social class-based) inequalities tended to be higher, in particular for health behaviours. Preliminary results also indicated that cultural value differences between countries may play a significant role in the evolution of adolescent health inequalities.
Conclusions
our findings suggest that between-countries’ cultural value differences may partly explain cross-national variations in adolescents’ health inequalities and in the evolution of these inequalities. By identifying cultural value differences in health, health inequalities and evolutions in health inequalities, this study helps informing policies better to tackle these inequalities.
Key messages
Cultural value differences between countries have a profound impact on the magnitude of inequalities in adolescents’ health and health behaviours and on the evolution of these inequalities. Identifying cultural value differences in adolescents’ health, health inequalities and evolutions in these inequalities is necessary to inform policies better to tackle these inequalities.

Abstract
BACKGROUND Regular physical activity (PA), a high level of fitness and a high diet quality are positively associated with health. However, information about stability of fitness components and diet quality indices is limited. This study aimed to evaluate stability of those parameters. METHODS This study includes 652 adults (men=57.56 (10.28) years; women=55.90 (8.34) years at follow-up) who participated in 2002-2004 and returned for follow-up at the Policy Research Centre Leuven in 2012-2014. Minutes sport per day and Physical activity level (PAL) were calculated from the Flemish Physical Activity Computerized Questionnaire. Cardiorespiratory fitness (CRF), morphological fitness (MORF; body mass index and waist circumference) and metabolic fitness (METF) (blood cholesterol and triglycerides) were used as fitness components. Diet quality indices (Healthy Eating Index-2010 (HEI), Diet Quality Index (DQI), Mediterranean Diet Score (MDS)) were calculated from a diet record. Tracking coefficients were calculated using Pearson/Spearman correlation coefficients (rPearson) and intra-class correlation coefficients (rICC). RESULTS In both men (rPearson&ICC=0.51) and women (rPearson=0.62 and rICC=0.60) PAL showed good stability, while minutes sport remained stable in women (rPearson&ICC=0.57) but less in men (rPearson&ICC=0.45). Most fitness components remained stable (r⩾0.50) except some METF components in women. In general the diet quality indices and their components were unstable (r<0.50). CONCLUSIONS PAL and the majority of the fitness components remained stable, while diet quality was unstable over 10 years. For unstable parameters such as diet quality measurements are needed at both time points in prospective research.

Abstract
BACKGROUND As the snacking pattern of European adolescents is of great concern, effective interventions are necessary. Till now health promotion efforts in children and adolescents have had only limited success in changing adolescents' eating patterns and anthropometrics. Therefore, the present study proposes an innovative approach to influence dietary behaviors in youth based on new insights on effective behavior change strategies and attractive intervention channels to engage adolescents. This article describes the rationale, the development, and evaluation design of the 'Snack Track School' app. The aim of the app is to improve the snacking patterns of Flemish 14- to 16-year olds. METHODS The development of the app was informed by the systematic, stepwise, iterative, and collaborative principles of the Intervention Mapping protocol. A four week mHealth intervention was developed based on the dual-system model with behavioral change strategies targeting both the reflective (i.e., active learning, advance organizers, mere exposure, goal-setting, monitoring, and feedback) and automatic processes (i.e., rewards and positive reinforcement). This intervention will be evaluated via a controlled pre-post design in Flemish schools among 1400 adolescents. DISCUSSION When this intervention including strategies focused on both the reflective and automatic pathway proves to be effective, it will offer a new scientifically-based vision, guidelines and practical tools for public health and health promotion (i.e., incorporation of learning theories in intervention programs).

Abstract
Regular cycling for transport is an important potential contributor to daily physical activity among adults. Characteristics of the physical environment are likely to influence cycling for transport. The current study investigated associations between perceived physical environmental neighbourhood factors and adults' cycling for transport across five urban regions across Europe, and whether such associations were moderated by age, gender, education and urban region. A total of 4,612 adults from five European regions provided information about their transport-related cycling and their neighbourhood physical environmental perceptions in an online survey. Hurdle models adjusted for the clustering within neighbourhoods were performed to estimate associations between perceived physical environmental neighbourhood factors and odds of engaging in cycling for transport and minutes of cycling for transport per week. Inhabitants of neighbourhoods that were perceived to be polluted, having better street connectivity, having lower traffic speed levels and being less pleasant to walk or cycle in had higher levels of cycling for transport. Moderation analyses revealed only one interaction effect by gender. This study indicates that cycling for transport is associated with a number of perceived physical environmental neighbourhood factors across five urban regions across Europe. Our results indicated that the majority of the outcomes identified were valid for all subgroups of age, gender, education and across regions in the countries included in the study.

Abstract
AIM This study aimed to assess convergent validity of International Physical Activity Questionnaire (IPAQ) interview (long form, last seven days), and to examine differences in reported physical activity and sedentary time between the self-administered and interview versions of the long IPAQ (last seven days); and whether these differences depend on gender, age, educational level and weight status. METHODS In total, 542 Belgian adults (45.3% male, 43.8±12.1 years) completed the IPAQ self-administered version. Data of these adults were compared with data of 542 adults (45.2% male, 43.5±12.3 years) who completed the IPAQ interview version and wore an accelerometer for seven consecutive days. Samples were matched on gender, age, education, neighborhood characteristics and time of data collection. RESULTS Convergent validity of the IPAQ interview version was moderate for total physical activity (Spearman ρ=0.37, P<0.001) and high for sedentary time (Spearman ρ=0.67; P<0.001). Bland-Altman plots showed that systematic and proportional biases were present for total physical activity; for sedentary time only systematic bias was present. Adults who completed the self-administered IPAQ reported higher means for most types of physical activity and less sedentary time than those who completed the IPAQ interview version. Differences between the two IPAQ versions were larger in males, lower-educated, older and overweight/obese adults. CONCLUSION Convergent validity of assessing total physical activity using IPAQ interview was similar to previous studies examining validity of the IPAQ, but stronger results were found for sedentary time. In general, and especially in males, lower-educated, older and overweight/obese adults, the use of the IPAQ interview version assessed by trained researchers, should be recommended to collect self-reported data on physical activity and sedentary time.

Abstract
Childhood overweight is a multifactorial health problem influenced by several factors. The interaction of behaviours such as physical activity, sedentary behaviour and eating behaviour determines whether or not a positive energy balance or weight gain is experienced. Knowing the correlates of these behaviours in 4- to 6-year-old children is of major interest for intervention development. According to the systematic literature search, attending a rural preschool was positively associated with physical activity. Gender, age and socioeconomic status were not associated with physical activity, while an indeterminate result was found for ethnicity. Gender and ethnicity were not associated with sedentary behaviour and indeterminate results were found for age and socioeconomic status. Preschoolers were more physically active as well as sedentary on weekdays. Watching television was associated with a higher consumption of snacks and sweet beverages. Strategies aiming to influence energy balance-related behaviours in preschoolers should target both boys and girls and all ethnic groups from low as well as high social status. During the week, there should be a focus on decreasing sedentary behaviour and in the weekend on increasing physical activity. Focusing on television viewing and the consumption of snacks and sweet beverages could/should also be a strategy.

Abstract
The purpose of this study was to investigate the benefits of a pedometer and a cognitive-behavioural group intervention for promoting physical activity (PA) in type 2 diabetes patients. We recruited 41 participants and randomized them into an intervention group (IG) (n=20) and a control group (CG) (n = 21). The intervention consisted of five sessions within 12 weeks, a booster session after 22 weeks and a pedometer. Primary outcome was PA assessed by accelerometer (minutes per day) and pedometer (steps per day). Secondary outcomes were weight, body mass index, blood pressure, haemoglobin A1c and total cholesterol. After 12 weeks, the IG increased with more than 2000 steps day(-1) compared with the CG, whereas sedentary behaviour decreased more than 1 hour day(-1) in the IG and showed no change in the CG. There was no intervention effect on the accelerometer-based PA nor on health measurements. After 1 year, the increase in steps per day remained significant in the IG, but sedentary activity increased again to baseline levels. This pilot study showed that the combination of a 12-week cognitive-behavioural intervention and a pedometer has a significant short-term impact on daily steps and sedentary behaviour but that the effects on total PA and long-term effects were limited.

Abstract
OBJECTIVE To determine if perceptions of the social and physical environment are associated with active transport and leisure-time sports among Belgian youth and to investigate if this relationship is moderated by self-efficacy. METHODS In February-May 2008, 1445 adolescents (17.4+/-0.6 yrs) were recruited in 20 randomly selected Belgian schools. Physical activity, psychosocial, and environmental factors were assessed using validated questionnaires. Moderated multilevel regression analysis was used to examine the association between physical activity and possible correlates. RESULTS Social environmental variables (modeling and social support) were positively associated with active transportation and leisure-time sports (p<0.05). Higher land use mix diversity, higher street connectivity, more attractive environments, better access to recreational facilities, and higher emotional satisfaction with the neighborhood were associated with more active transportation (p<0.05). Higher perceived safety from traffic, better access to recreational facilities, more physical activity equipment at home, and fewer electronic devices in the bedroom were associated with more leisure-time sports (p<0.05). Lower perceived safety and poorer access to (recreational) facilities were only associated with lower active transport among youth with lower self-efficacy (p<0.05). CONCLUSION Creating more supportive environments could have the potential to affect the physical activity levels of Belgian adolescents with both high and low self-efficacy.

Abstract
AbstractObjectiveThe aim of the present study was to examine the mediation effects of changes in psychosocial determinants of physical activity (attitude, social support, self-efficacy, perceived benefits and barriers) on changes in physical activity.DesignOne-year intervention study with baseline and 1-year post measures of physical activity habits and psychosocial correlates.SettingFifteen middle schools.SubjectsBoys and girls (n = 2840) aged 11–15 years completed the validated questionnaires during class hours.ResultsThe product-of-coefficients test was used to asses the mediating effects. Self-efficacy for physical activity at school was found to be the only significant mediator of physical activity change. Specifically, self-efficacy for physical activity at school partly mediated the effect of the intervention on total and school-related physical activity change in the intervention group with parental support (P < 0.05). None of the other potential mediators, attitudes, social support, perceived benefits and perceived barriers, seemed to have had a positive effect. Even a suppressor effect was found for attitudes. Given that the effects of self-efficacy and attitudes were of opposite direction, the total mediated/suppressed effects of the intervention were not statistically significant.ConclusionsPositive changes in total and school-related physical activity in adolescents could be partly explained by increases in self-efficacy for physical activity at school through a physical activity intervention in middle schools with parental support. However, the suppressor effect of attitudes decreased this effect. As this is one of the first true mediation analyses in this age group, further research is needed to replicate the importance of these mediators.

Abstract
AIM Some studies found lower levels of physical activity and fitness in overweight children, compared to normal weight children, while others have failed to observe any difference. Therefore, the purpose of the present study was to reinvestigate the differences in physical activity and running capacity between overweight and normal weight children. METHODS A random sample of 121 males and 101 females, 11 to 13 years old, was selected. Children were divided into overweight/fat and normal weight/fat groups based on measures of body mass index and percentage of body fat. Physical activity level was assessed by accelerometers and a Physical Activity Questionnaire. Running capacity was measured by the Cooper Test. RESULTS Accelerometer data revealed that overweight/fat children were less moderate to vigorous physically active when compared to normal weight/fat children. They also performed worse on the running capacity test (P<0.001). Overweight children reported to be less active in leisure time (P<0.05) compared to normal weight children. Overfat girls reported to participate less in sports activities compared to normal fat girls (P<0.05). CONCLUSION The present study found clear differences in physical activity and running capacity between overweight/fat and normal weight/fat 11- to 13-year olds. A major strength of the present study is that similar results were shown based on different estimates of overweight and activity in a relatively large sample of children.

Abstract
OBJECTIVE The present study aimed at investigating the influence of food availability, rules and television viewing habits on eating behaviours in adolescents. DESIGN Cross-sectional study. SETTING Four randomly selected middle schools. SUBJECTS A sample of 534 seventh and eighth graders. INTERVENTIONS Validated questionnaires were used to measure the family environment and fat, soft drink and fruit consumption. Hierarchical regression analyses on fat, soft drink and fruit consumption, with demographic and psychosocial variables entered as the first and environmental factors as the second block were conducted in boys and girls. RESULTS Boys with more unhealthy products available at home consumed more fat (P< or =0.001, 95% CI: 8.2-29.4) and more soft drinks (P< or =0.01, 95% CI: 0.2-1.4). Boys who reported better television viewing habits ate more fruit (P< or =0.001, 95% CI: -1.7 to -0.5). Girls who reported better television viewing habits consumed less fat (P< or =0.01, 95% CI: 1.4-9.0) and more fruit (P< or =0.05, 95% CI: -1.0 to -0.1). Girls who reported higher availability of healthy products at home (P< or =0.05, 95% CI: 0.3-3.1) and more food rules (P< or =0.001, 95% CI: -1.8 to -0.5), consumed more fruit. Environmental factors were poor predictors of soft drink consumption among girls. CONCLUSION Availability of (un)healthy food products, family food rules and TV viewing habits were related to one or more eating behaviours in boys or girls. Although home environmental factors can play an important role in influencing adolescents' eating behaviours, these factors were generally less predictive than demographic and psychosocial variables.

Abstract
This study investigated the effect of post-treatment phone contact on weight-loss maintenance and activity behaviour in obese youngsters. In all, 20 patients who completed a weight reduction program were randomly assigned to a 5-month maintenance programme (experimental) or control condition. Following the maintenance programme, patients sent a weekly activity diary to the therapist, who in turn phoned them biweekly to discuss their activities. Body weight, stature and physical activity were measured before and after the maintenance programme. The control group showed a continuous increase in overweight after initial treatment, while the experimental group showed a steep increase during the summer holidays (no intervention), but this increase slowed down during the maintenance programme (P<0.05). Moderate-to-high intensity activities increased during the maintenance programme in the experimental group, but decreased in the control group (P<0.001). In conclusion, post-treatment phone contact appears to have the potential to be an effective maintenance strategy in obese youngsters.

Effects of distraction on treadmill running time in severely obese children and adolescents. Int J Obes (Lond) 2002; 26:1023-9. [PMID: 12119566 DOI: 10.1038/sj.ijo.0802052] [Citation(s) in RCA: 30] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/24/2001] [Revised: 02/05/2002] [Accepted: 03/15/2002] [Indexed: 11/09/2022]
Abstract
OBJECTIVE (1) To examine the effects of attentional distraction on running time in an incremental treadmill test in obese youngsters; (2) to investigate whether distraction works at the same extent at the beginning and at the end of residential treatment; and (3) to explore the underlying mechanisms of the possible distraction effects. METHODS Thirty severely obese youngsters (10 boys, 20 girls, age range 9-17) who were following a 10 month residential treatment, performed a treadmill test until exhaustion in four different sessions using a within subjects design. The two sessions at the beginning of the treatment and the two sessions at the end the treatment were counterbalanced, one with attentional distraction (music) and one without distraction. RESULTS Obese youngsters ran significantly longer during distraction. This distraction effect seemed to be larger at the beginning compared to at the end of obesity treatment. The absence of differences between the condition with music and the condition without music on perceived bodily symptoms is in line with the idea that it took longer to perceive sufficient bodily sensations to decide to stop the treadmill test in the distraction condition. This interpretation is further corroborated by the physiological data indicating a superior peak performance in the condition with distraction. CONCLUSIONS Attentional distraction has a positive effect on perseverance in obese youngsters. Further research has to show the usefulness of attentional distraction as a technique to increase exercise adoption and adherence in obesity treatment.

Differences in psychosocial determinants of physical activity in older adults participating in organised versus non-organised activities. J Sports Med Phys Fitness 2000; 40:362-72.

Abstract
BACKGROUND With the introduction of the new consensus on 30 minutes of moderate physical activity preferably on all days of the week, exercise implemented into daily activities is promoted whereas structured activity programs lose importance. Activity levels of most older people don't come up with current recommendations. Therefore strategies to enhance attendance of older adults in physical activities should be developed. Group programs may be more effective in changing exercise behaviour of older adults than non-supervised physical activity. The purpose of this study was to investigate the differences in level of activity and psychosocial determinants of physical activity between seniors involved in an exercise class and seniors not engaged in any organised physical activity. METHODS Seventy-five elderly who were currently involved in structured exercise classes and 75 elderly who did not participate in any organised physical activity during the previous year were recruited in senior citizens' centres and were asked to fill out a questionnaire. RESULTS Subjects involved in an exercise program had higher levels of activity and reported more social influences and higher self-efficacy compared to the respondents practising on an individual basis. No differences were found in perceived barriers or benefits. CONCLUSIONS Exercising in a group program gives the opportunity to accumulate some extra physical activity and positively affects the level of activity outside the program. Stimulating older adults to join a structured activity program in the company of family or friends in order to enhance supporting social influences and perceived competence could be an important intervention strategy.
