he association of total and abdominal obesity with Health-Related Quality of Life in a sample of Greek healthy adults

Background: in the Greek population, the association between obesity and Health-Related Quality of Life (HRQoL) has not been examined so far. Thus, the purpose of the present study is to explore obesity-related predictors of HRQoL in a sample of Greek healthy adults. Methods: a cross-sectional design was used. The sample consisted of three hundred twenty seven healthy men (N=105) and women (N=222), between the ages of 30 and 50 years (mean age=39.57 ± 6.68) who lived in Athens. Body mass index (BMI), waist to hip ratio (WHR), and body fat (BF) were assessed. HRQoL was evaluated using the short-form 36 (SF-36) health survey, which consists of eight subscales and two health factors (physical and psychological health). Socio-demographic variables and health-related behaviours were assessed by questionnaires. Separate hierarchical regression analyses were conducted to examine the associations between BMI, WHR, BF and SF-36 health survey subscales and factors. Results: socio-demographic and health-related variables were moderately associated with the HRQoL subscales and factors. Furthermore, after controlling the socio-demographic variables and health-related behaviours, (a) BMI negatively predicted the physical functioning, physical role, bodily pain, and social functioning subscales, as well as the physical health factor and (b) WHR and BF negatively predicted the physical functioning subscale. However, the obesity indexes did not predict other psychological health subscales. Conclusions: the results indicated negative associations of BMI, WHR, BF with physical functioning and health in a sample of Greek healthy adults. Such data relating total and abdominal obesity to HRQoL, as assessed by BMI, WHR, and BF, have not been reported until now in the literature. One limitation of this study was that the sample size was relatively small and the results could not be generalized to the entire Greek population

CRITERION, CONSTRUCT AND FACTORIAL VALIDITY OF THE GREEK VERSION OF THE INTERNATIONAL PHYSICAL ACTIVITY QUESTIONNAIRE-SHORT FORM (IPAQ-SF)

The current study investigated the validity of the Greek version of the International Physical Activity Questionnaire-short form (IPAQ-SF, seven days recall period, Craig et al., 2003). Specifically, criterion and construct validity were examined in a sample of 120 adults (M ± SD = 30.52 ± 14.87 years). In addition, factorial validity and internal consistency were examined in a second sample of 726 physically active adults (M ± SD = 38.80 ± 13.64 years). Further, associations were examined among the IPAQ-SF, exercise self-efficacy, body mass index and various socio-demographic variables. The statistical analyses indicated: (a) acceptable validity coefficients and factorial validity of the IPAQ, (b) acceptable internal consistency, (c) higher physical activity values in men compared to women and in athletes compared to non-athletes, (d) positive correlations between physical activity levels, exercise self-efficacy and past physical activity and (e) negative correlations among physical activity, age, number of children and body mass index. The Greek version of the IPAQ-SF was valid and therefore, could be useful for assessing physical activity.  Article visualizations

THINKING GLOBALLY AND ACTING LOCALLY: THE POWER OF PLAY AND GAMES

The European Commission has long acknowledged the important role of sport and physical education in promoting public health, a healthy lifestyle and social well-being, together with socio-cultural integration, namely social inclusion in and through sport, as we had all pointed out in the project description. One need also reiterate here—in order to contribute to the brainstorming of our upcoming meeting in Zaragoza—that a great number of studies have shown, not only the health benefits, but the social importance of physical activity and sport, specifically the social capital of sport: sport agency and volunteerism, i.e. the sport potential in promoting social inclusion and reducing or eliminating social, ethnic and gender prejudices (Kamberidou 2012, 2011; Hall 2012; Hardin & Greer 2009). Gender equality, essential from a human rights perspective [...] (see attached article: discussion and proposals

Neighborhood environment, physical activity, and quality of life in adults: Intermediary effects of personal and psychosocial factors

AbstractBackgroundStudies have indicated that there is a positive and indirect relationship between physical activity (PA) and quality of life (QoL). The current study examined this relationship through a social cognitive model with consideration to the intermediary effects of exercise self-efficacy, and physical (PCS) and psychological (MCS) health. Additionally, this model was widened to include concepts from the ecological theory, and any causal associations among neighborhood environment, PA, and QoL.MethodsSix hundred and eighty-four physically active adults (39.16 ± 13.52 years, mean ± SD), living in Athens, Greece, completed a series of questionnaires measuring PA, QoL, exercise self-efficacy, PCS, MCS, neighborhood environment, and family and friend support for PA. The examined models were analyzed using structural equation modeling.ResultsThe social cognitive and ecological models proved to be of appropriate fit. Within the social cognitive model, PA positively affected QoL through the mediating effects of exercise self-efficacy, PCS, and MCS. With regards to the ecological model, neighborhood environment positively influenced QoL through the intermediary effects of family support for PA, exercise self-efficacy, PA, PCS, and MCS.ConclusionResults indicated that the most important mediators in the examined models were exercise self-efficacy and health. Further, findings demonstrated the role of neighborhood environment in enhancing PA and QoL. Future studies should be carried out applying longitudinal data for a better understanding of these associations over time

Flow experience and athletes' performance with reference to the orthogonal model of flow

The purposes of the current study were to examine (a) the differences in Flow State Scale (FSS) subscales between the 4 experiential states of the orthogonal model (apathy, anxiety, relaxation, and flow), (b) the relationship between challenge, skills, and flow experience; and (c) the relationship between flow experience and athletes' performance. Two hundred twenty athletes volunteered to participate in this study. Challenge of the game and skills of the athlete were measured before and after competition. Thirty minutes after the competition, the FSS was used to measure flow experience. In addition, subjective and objective measures of athletes' performance were assessed. Athletes in the flow and relaxation states revealed the most optimal states, whereas the athletes in the apathy state showed the least optimal state. There were positive associations between athletes' flow experience and their performance measures, indicating that positive emotional states are related to elevated levels of performance. On the other hand, there were low or no correlations between athletes' performance and reported challenge of the game, whereas skills of the athlete were moderately correlated with flow. Multipleregression analysis demonstrated significant prediction of athletes' performance based on flow experience during competition. Future research should examine the relationship between flow, athletes' performance, and additional dispositional and state variables

Children's self-efficacy and proxy efficacy for after-school physical activity

Problem: This study evaluated the psychometric properties of a scale measuring children's self-efficacy and proxy efficacy for physical activity at after-school programs and at home. Proxy efficacy was defined as children's confidence in their skills and abilities to get adults to act in their interest to provide physical activity opportunities. Methods: Children (grades 4 through 6) attending after-school programs completed a self-efficacy questionnaire relevant to their physical activity. Factorial validity was assessed with an exploratory factor analysis (n = 107) and a confirmatory factor analysis (n = 187). Next, criterion-related validity was assessed using a mixed-model analysis of covariance with school as a random effect and children level variables as fixed effects. Internal consistency reliability was assessed using Cronbach's alpha. Results: The questionnaire assessed three separate constructs: self-efficacy to be physically active (SEPA), proxy efficacy to influence parents to provide physical activity opportunities (PEPA-P), and proxy efficacy to influence after-school staff to provide physical activity opportunities (PEPA-S). Males had greater SEPA than females. Children who perceived greater physical activity opportunities during after-school time had greater SEPA, PEPA-P, and PEPA-S than children attending schools with fewer physical activity opportunities. Children attending schools with lower concentrations of racial/ethnic diversity and higher socioeconomic status (SES) had greater PEPA-P compared to children attending greater racial/ethnic diversity and low-SES schools. Conclusions: Self-efficacy for physical activity is a multicomponent construct and can be assessed in elementary-aged children using the reliable and valid instrument confirmed in the current study
