“…In the present study inadequate help with clinical difficulties was associated with increased BMI. Thus, although we found no direct correlation between BMI and PA, as would be expected 40) a specific component of instrumental social support 41) relevant to the physician's work environment was significantly associated with these two LRCRF. In the OSI lack of social support is incorporated into the conflict aspect.…”

. Participants completed the physician-specific version of the Occupational Stress Index (OSI). Self-reported data concerning LRCRF and working conditions were cross-validated with medical records, as well as with worksite measurements and expert observations. A total of 35 (31.3%) of the physicians were current smokers and 10 (8.9%) were heavy smokers (>20 cigarettes/day); 23 (20.5%) had a body mass index (BMI) of 28 or more, and 11 (9.8%) were obese (BMI≥30). Only 27 (24.1%) regularly engaged in recreational physical activity (PA). Slightly over 5% consumed alcohol daily. Altogether 15 (13.4%) had a low lifestyle-related cancer risk profile (not a current smoker, BMI<28, regular recreational PA and no daily alcohol consumption). Total OSI and several OSI aspects, particularly threat avoidance alone or in combination, showed significant multivariate associations with LRCRF, as did individual OSI elements. The latter included long work hours, restricted problem-solving strategy, insufficient help with clinical difficulties and supervisory responsibility (obesity and/or sedentariness) and problems hampering patient care (smoking). There is an urgent need to lower the LRCRF among female physicians in Field Studythis high risk region. Our findings suggest that diminishing the work stressor burden should be considered when developing intervention strategies aimed at these risk factors. (J Occup Health 2007; 49: 61-71)

“…Additionally, the degree to which social support influences physical activity may vary by age, where in comparison to young females, greater influence of social support on physical activity has been found in middle to older aged females (DeBourdeaudhuij & Sallis, 2002). In general, higher levels of social support from family and friends are identified as important determinants of physical activity behavior among women, older adults, and overweight populations (Blanchard et al, 2005;Booth et al, 2000;Castro et al, 1999;Eyler et al, 1999). Interestingly, social support is also associated with frequency, intensity, and duration of activity (Eyler et al, 1999), and it may be especially important for MVPA performed in the leisure domain (Sternfeld, Ainsworth, & Queensberry, 1999).…”

“…However, understanding physical activity may alleviate her symptoms or eventually give her more energy may support her self-efficacy expectations. In addition to the five sources of selfefficacy information, recent investigations established a link between the perceived social and physical environment with self-efficacy (Blanchard et al, 2005;Cerin et al, 2008).…”

Osteoporosis (OP) is a disease characterized by low bone mass and structural breakdown of the skeleton. The disease may be prevented through weight-bearing, moderate to vigorous physical activity (MVPA), which is important for peri-and postmenopausal women who are at great risk for OP. However, most women do not participate in activity according to guidelines, which can negatively impact bone health.A better understanding of multi-dimensional factors that influence MVPA may help inform physical activity interventions aiming for OP prevention. The purpose of this study was to utilize social cognitive theory (SCT) to understand the associations between social cognitive factors and MVPA among peri-and postmenopausal women.Eighty-seven peri-and postmenopausal women (aged 43 to 65) completed this cross-sectional study. Participants completed demographic, health, calcium, and SCT questionnaires. SCT variables assessed included task self-efficacy (SE T ) and barrier selfefficacy (SE B ), perceived social support from friends (SS FR ) and family (SS FA ), and perceived access to facilities (AC F ) and home equipment (AC H ). Participants wore an NL-1000 pedometer for one week to assess total steps per day and minutes spent in MVPA. Past year MVPA, past week leisure MVPA, and past week occupational/ transport MVPA were assessed with the Modifiable Activity Questionnaire.Stepwise regression analysis was used to identify the direct relationships between cognitive variables and each of the physical activity outcome measures. Moderationmediation analysis was conducted to determine if significant interaction effects or confounding effects existed between social cognitive variables and each physical activity ii Finally, I would like to acknowledge the many women who gave of their time to participate in this study. In addition, I would like to acknowledge, the University of Iowa STAR Registry for allowing me access to registry participants, the National Osteoporosis Foundation for donating the brochures that were given to the participants, and Dr. JanetSchlechte and De Frei for allowing me to borrow the Sahara Heel Ultrasound. The valuable contribution of time and resources on the part all of these individuals were fundamental to this project.iii ABSTRACT Osteoporosis (OP) is a disease characterized by low bone mass and structural breakdown of the skeleton.

“…Relationships with others have a strong influence on behavior as these relationships provide models for change, controls and constraints to behavior, access to information, and a sense of meaning that can help make healthy lifestyle changes (diet and physical activity) more attainable (Blanchard et al, 2005). Having people who are supportive in one's life is critical to initiating and maintaining the process of behavior change.…”

“…It is estimated that children and adolescents who spend 2 or more hours a day doing sedentary activity have an increased risk of high cholesterol, diabetes, poor fitness, and being overweight in adulthood (Hancox et al, 2004 ). Being overweight further exacerbates the aforementioned risk factors and decreases the likelihood that the person will engage in physical activity (Blanchard et al, 2005).…”

A computer based approach to improve the dietary and physical activity patterns of a diverse group of adolescents

Professor Michele Ciccazzo, Major ProfessorDiet and physical activity patterns have been implicated as major factors in the increasing prevalence of childhood and adolescent obesity. It is estimated that between 16 and 33 percent of children and adolescents in the United States are overweight (CDC, 2000). Moreover, the CDC estimates that less than 50% of adolescents are physically active on a regular basis (CDC, 2003). Interventions must be focused to modify these behaviors. Facilitating the understanding of proper nutrition and need for physical activity among adolescents is the first step in preventing overweight and obesity and delaying the development of chronic diseases later in life (Dwyer, 2000). The purpose of this study was to compare the outcomes of students receiving one of two forms of education (both emphasizing diet and physical activity), to determine whether a computer based intervention (CBI) program using an interactive, animated CD-ROM would elicit a greater behavior change in comparison to a traditional didactic intervention (TDI) program. A convenience sample of 254 high school students aged 14-19 participated in the 6-month program. A pre-test post-test design was used, with follow-up measures taken at three months post-intervention.v No change was noted in total fat, saturated fat, fruit/vegetables, or fiber intake for any of the groups. There was also no change in perceived self-efficacy or perceived social support. Results did, however, indicate an increase in nutrition knowledge for both intervention groups (p<0.001). In addition, the CBI group demonstrated more positive and sustained behavior changes throughout the course of the study. These changes included a decrease in BMI (ppre/post<0.001, Ppost/follow-up<0.001), number of meals skipped (ppre/post<0.001), and soda consumption (ppre/post=0.003, Ppost/follow-up=0.03) and an increase in nutrition knowledge (ppretpost<0.001, Ppretronow-up<0.001), physical activity (ppretpost<0.05, Ppre/follow-up <0. 0 1 ), frequency of label reading (ppre/follow-up <0. 0 1) and in dairy consumption (ppre/post=0.03). The TDI group did show positive gains in some areas post intervention, however a return to baseline behavior was shown at follow-up. Findings of this study suggest that compared to traditional didactic teaching, computer-based nutrition and health education has greater potential to elicit change in knowledge and behavior as well as promote maintenance of the behavior change over time.
