Abstract: We surveyed 135 randomly selected members of an urban YMCA facility in Massachusetts to examine self-reported (1) physical activity, (2) dietary behaviors, (3) body mass index, and (4) correlates of behavior change among short-term (i.e., one year or less) and long-term (i.e., more than one year) members. Chi-square tests were used to assess bivariate associations between variables, and multivariate linear regression models were fit to examine correlates of health behaviors and weight status.Eighty-nine percent of short-term and 94% of long-term members reported meeting current physical activity recommendations. Only 24% of short-term and 19% of long-term members met fruit and vegetable consumption recommendations, however, and more than half were overweight or obese. Length of membership was not significantly related to weight status, dietary behaviors, or physical activity. Most respondents were interested in changing health behaviors, in the preparation stage of change, and had high levels of self-efficacy to change behaviors. Short-term members had less education (p = 0.02), lower household incomes (p = 0.02), and were less likely to identify as white (p = 0.005) than long-term members. In multivariate models, females had lower BMI than males (p = 0.003) and reported less physical activity (p = 0.008). Physical activity was also inversely associated with age (p = 0.0004) and education (p = 0.02).Rates of overweight/obesity and fruit and vegetable consumption suggested that there is a need for a weight control intervention among members of an urban community YMCA. Membership in such a community wellness facility alone might not be sufficient to help members maintain a healthy weight. The data indicate that YMCA members are interested in making changes in their dietary and physical activity behaviors. Targeting newer YMCA members might be an effective way of reaching underserved populations. These data will help inform the development of a weight control intervent

Abstract: With the rapid development of online community, it is a challenge for many community operators to retain existing users. By integrating perceived investment and perceived benefit that user achieves through online community usage, we propose a research model to investigate the determinants of perceived irreplaceability of online community users. Based on the data collected from 336 users of online community, we empirically test the proposed model. The results of structural equation modeling analysis indicate that personalization, learning and hedonic value jointly determine online users’ perceived irreplaceability.
Dynamics of Perceived Support and Work Attitudes: The Case of Fitness Club Employees
Human Resource Management Research , 2012, DOI: 10.5923/j.hrmr.20120201.02
Abstract: One of the significant sources of competitive advantage for an organization is its human capital. Focusing on human capital, the purpose of the study was to examine the impact of perceived support available at work place on organizational commitment, and the impact of organizational commitment on work effort and intention to leave. In addition, the moderating effects of motivation on the relationship between perceived support and organizational commitment was investigated. Confirmatory factor analysis, structure equation modeling, and regression analysis were carried out to test the hypothesized relationships in the data provided by 202 fitness club employees across the United States. The results showed that perceived support explained 79% of the variance in organizational commitment, and organizational commitment significantly and positively influenced work effort (16%) and negatively influenced intention to leave the organization (61%). Further, intrinsic motivation was found to moderate the relationship between perceived support and affective commitment to the organization. The results of the study significantly contribute to the body of knowledge and provide meaningful managerial implications.

Abstract: Information and communication technology (ICT) is indeed an important tool to expose the rural community to development. Realizing the importance of ICT, a number of high impact ICT programs and projects have been introduced by the government. However, do the rural community especially their leaders which are the Village Development and Security Committee members (JKKK) use ICT? And more importantly do they perceive ICT as useful in their daily activities and tasks? This question brings us to the main objective of this paper which is to know the factors that influence the perceived usefulness towards ICT usage among the JKKK members in Peninsular Malaysia. Besides, this paper intends to investigate the level of perceived usefulness towards ICT usage among JKKK members and to reveal the most significant contributors for perceived usefulness towards ICT usage. This is a quantitative study whereby data were gathered using a questionnaire. Based on the multi stage random sampling, a total of 240 JKKK members have been selected as the respondents. Based on the analyses done, it can be concluded that respondents studied do have a high level of perceived usefulness towards ICT usage. All of the four factors studied have a positive and significant relationship towards ICT usage. Attitude was identified as the most significant contributor for perceived usefulness towards ICT usage while the four predictor variables explain about 60.0% of the variance/variation in perceived usefulness towards ICT usage.

Abstract: digital ecosystems, or it-ecosystems (ites), are composed of multiple and independent entities such as individuals, organizations, services, software, and applications. together, these elements create a number of new independent systems that operate and communicate with their own infrastructure (man to machine; machine to machine; person to person), sharing one or several missions. a better understanding of how ites and their interconnected components create benefits and added value for different types of consumers is of particular importance to the establishment of digital environments and to managing their resources. considering different components of perceived trust in ites, we rely in this paper on a multi-dimensional framework of trust effects that includes system-centric as well as user-centric determinants of trust. based on our conceptual model, we develop two sets of propositions. the first ones address technological drivers of trust in ites, whereas the second set of propositions considers individual as well as social drivers of trust. the model and propositions are discussed with reference to preliminary empirical results as well as to future research steps and business implications.

Abstract: The purpose of this study was to assess the anthropometric determinants of hypokinetic fitness status of sedentary women. The total of two hundred (200) participants was randomly drawn participated in the study. Three variables were examined to reveal the fitness status of selected women. Thus, the f-value of bloodpressures, body mass index and percentage body fat were 3.144, .797; .737; and 1.823 respectively. It was therefore discovered that anthropometric parameters such as blood pressures, BMI [weight and height], percentage body fat are strong determinants in the assessment of fitness status and the risks of developing hypokinetic diseases among women. It clearly observed that mortality rate is on theincrease from diseases associated with sedentary living. Therefore, it has become necessary for Nigerians especially the women folks to recognize the dividends of living a healthy and physically active life.

Abstract: Objective: The aim of this study was to investigate the associations among measured physical fitness, perceived fitness, intention towards future physical activity and self-reported physical activity through junior high school years. Methods: Study participants included 122 Finnish students who were 13 years old during Grade 7. The sample was comprised of 80 girls and 42 boys from 3 junior high schools (Grades 7-9). During the autumn semester of Grade 7, students completed fitness tests and a questionnaire analyzing self-perception of their physical fitness. The questionnaire delivered at Grade 8 included intention towards future physical activity. At Grade 9 students’ self-reported physical activity levels. Results: Structural Equation Modelling revealed an indirect path from physical fitness to self-reported physical activity via perceived physical fitness and intention towards future physical activity. The model also demonstrated a correlation between perceived physical fitness and physical activity. Squared multiple correlations revealed that perceived physical fitness explained 33 % of the actual physical fitness. Conclusions: The results of this study highlight the role of physical and cognitive variables in the process of adoption of physical activity in adolescence.

Abstract: Background and Aim: Demographic, physical, social and psychological factors make breastfeeding and its maintenance complex. Despite extensive breastfeeding promotion programs, no progress has been achieved. As breastfeeding is a phenomenon embedded in culture and folk perceptions, identification of its key determinants is essential when designing policies and implementing programs. Materials and Methods: In this qualitative study, data were collected from 35 health professionals through a 4-day group interview using a structured questionnaire (open-end questions). The participants were purposefully recruited from among the health professionals attending a 4-day breastfeeding promotion workshop. Results: The determinants of breastfeeding were categorized into 2 main domains, namely, peoples perception of breastfeeding phenomenon and approaches employed in its promotion. The former domain was described by beliefs, demographic characteristics, social variables, and indigenous theories, and the later by practice in the cultural and social context, policies, interactions and practical skills. Conclusion: From the participants perspective, misperceptions of people can determine the degree of success or failure of a breastfeeding promotion program. Our findings confirm that peoples perceptions are deeply influenced by their demographic characteristics, folk theories and social variables. As regards the breastfeeding promotion domain, the barriers are social-cultural factors rooted in the local beliefs and folk theories. The participants listed the breastfeeding promotion determinants as lactation policies and health providers performance related to their skill in effective communication with mothers. Our findings also indicate that wrong beliefs, maternal and child diseases, caesarian section, and mothers employment were believed to be deterrents in promoting breastfeeding in the community and that pediatricians, obstetricians and other health professionals can play key roles in the field. Based on our findings, we can further conclude that the phenomenon of breastfeeding and its maintenance are deep-rooted in social structure and cultural diversity. When designing and implementing breastfeeding promotion programs, local variables and determinants should be taken into consideration.

Abstract: Introduction. Inequalities in health are evident in the whole world and present an important and consistent public health issue. The highest contribution to the inequality in heath is attributable to the demographic and socioeconomic determinants of health. Objective. The aim of this study was to analyze the association between the demographic (gender, age, marital status and type of settlement) and socioeconomic determinants of health (education and Wealth Index), and self-perceived health. Methods. In the study the data from 2006 National Health Survey of the population of Serbia were used. The interview involved 14,522 adults aged ≥20 years. The association between the demographic and socioeconomic determinants of health as independent variables, and self-perceived health as dependent variable were examined using bivariate and multivariate logistic regression analyses. The minimum level of significance was p<0.05. Results. According to our study, the elderly and females significantly more often perceived their health as poor. Respondents living in rural settings were less likely to perceive their health as poor compared to those living in urban settings (odds ratio was 0.82 in males and 0.75 in females). Males with low education were three times more likely to perceive their health as poor (odds ratio was 3.46) in relation to males with high education. This association was more pronounced in females (odds ratio was 5.37). The same pattern was observed for Wealth Index. Conclusion. This study showed that demographic and socioeconomic inequalities in self-perceived health are present in Serbia. Comprehensive public health policies and interventions for reducing these inequalities are urgently needed with the primarily focus on the most disadvantaged socioeconomic groups.

Abstract: Aims Abnormal physiological stress reactivity is increasingly investigated as a vulnerability marker for various physical and psychological health problems. However, studies are inconsistent in taking into account potential covariates that may influence the developing stress system. We systematically tested determinants (individual, developmental, environmental and substance use-related) of physiological and perceived physiological stress reactivity. We also examined the relation between physiological and perceived physiological stress reactivity. Method In a stratified sample of 363 children (7–12 years) and 344 adolescents (13–20 years) from the general population, we examined cortisol, heart rate, respiratory sinus arrhythmia and perceived physiological stress reactivity to a psychosocial stress procedure. Results Using multivariate linear regression models, we found that individual, developmental, environmental and substance use-related factors were related to each of the stress response indices. These determinant factors were different for each of the stress reactivity indices, and different in children versus adolescents. Perceived physiological stress reactivity predicted cortisol reactivity in adolescents only. All other relations between perceived physiological and physiological stress reactivity were not significant. Conclusions As physiological stress variables are often examined as vulnerability markers for the development of health problems, we maintain that it is essential that future studies take into consideration factors that may account for found relations. Our study provides an overview and indication of which variables should be considered in the investigation of the relation between physiological stress indices and illness.
