Change in behavioral exercise program-associated self-regulation enhances self-regulation-induced eating improvements across levels of obesity severity

Architects of behavioral weight-loss programs require improved understandings of psychosocial correlates of healthy eating behaviors to improve overwhelmingly poor outcomes. Exercise might benefit eating changes through a transfer of self-regulatory skill improvements. However, related research is minimal, and degrees of obesity might influence the utilization and efficacy of self-regulatory processes. Women of Class 1 obesity (body mass index [BMI] = 30–34.9 kg/m²; n = 53), Class 2 obesity (BMI = 35–39.9 kg/m²; n = 41), and Class 3 obesity (BMI ≥ 40 kg/m²; n = 53) enrolled in a community-based cognitive-behavioral weight-management program were assessed over 6 months on changes in exercise, self-regulation for both exercise and eating, and the consumption of fruits/vegetables and sweets. Within-group improvements were all significant, with the greater self-regulation changes consistent with lower degrees of obesity. Within serial multiple mediation analyses, the hypothesized path from exercise change→self-regulation for exercise change→self-regulation for eating change→eating behavior change was supported in both the prediction of changes in fruit/vegetable intake and sweets consumption. However, the direct effect of increased exercise on improved eating was not significant. BMI score or obesity class did not significantly moderate embedded relationships among variables. Findings suggested weight-loss programs incorporate supported exercise, and dedicate high proportions of their curricula to the development of self-regulatory skills.     

Testosterone deficiency in male heart failure patients and its effect on endothelial progenitor cells

Background: Endothelial progenitor cells (EPCs) are thought to contribute to reendothelialization and neoangiogenesis. Since it is known that EPCs express a testosterone receptor, we wanted to assess the prevalence of testosterone deficiency in patients with CHF and its impact on circulating EPCs. Methods: 137 male patients with chronic heart failure (CHF) were included (age 61?±?13 years; BMI 29?±?5?kg/m²; New York Heart Association classification (NYHA) I: n = 47, NYHA II: n = 51, NYHA III: n = 39). Numbers of different populations of circulating EPCs were quantified using flow cytometry. Levels of free testosterone and EPC-regulating cytokines were determined using ELISA. Results: The prevalence of testosterone deficiency in our University CHF clinic was 39%. However, there was no difference between patients with and without testosterone deficiency regarding their levels of EPCs. Testosterone levels were inversely correlated with age (R² = ?0.32, p = 0.001) and NYHA status (R² = 0.28, p = 0.001) and correlated with cardiorespiratory capacity (R² = 0.26, p = 0.03). Conclusion: Testosterone deficiency is frequent in male patients with CHF but does not appear to impact the regenerative EPCs.     

Assessing Overweight,Obesity, Diet,and Physical Activity in College Students

Abstract

The authors surveyed 738 college students aged 18 to 27 years to assess overweight, obesity, dietary habits, and physical activity. They used BMI (body mass index) > 25 kg/m² or BMI > 85th percentile and BMI > 30 kg/m¹ or BMI > 95th percentile to estimate overweight and obesity in those aged < 19 years. To define overweight and obesity in those > 20 years, they used BMI > 25 kg/m² and > 30 kg/m². They found overweight rates of 21.6% using BMI directly and 16.2% using BMI percentile and obesity rates of 4.9% using BMI directly and 4.2% using BMI percentile. More than 69% of the participants reported < 5 servings of fruits and vegetables per day and more than 67% reported < 20 g of fiber per day; participants reported physical activity on fewer than 3 d/wk. Most college students are not meeting dietary and physical activity guidelines, suggesting the need for prevention interventions and increased understanding of overweight in college students.     

Pilot Testing a Cognitive-Behavioral Protocol on Psychosocial Predictors of Exercise,Nutrition, Weight,and Body Satisfaction Changes in a College-Level Health-Related Fitness Course

Abstract

Objective: Small-scale pilot testing of supplementing a required college health-related fitness course with a cognitive-behavioral exercise-support protocol (The Coach Approach). Participants: Three classes were randomly assigned to Usual processes (n = 32), Coach Approach–supplemented: Mid-size Groups (n = 32), and Coach Approach–supplemented: Small Groups (n = 34) conditions. Methods: Repeated-measures analyses of variance (ANOVAs) assessed overall and between-class changes in the behavioral/physiological factors of exercise, fruit/vegetable intake, and body mass index (BMI); and the psychosocial factors of self-regulation, exercise self-efficacy, mood, and body satisfaction. Dependent t tests evaluated within-class changes. Multiple regression analyses tested prediction of exercise by changes in self-regulation, self-efficacy, and mood. Results: Significant improvements in self-regulation and fruit/vegetable intake were found in all classes. The Coach Approach–supplemented classes demonstrated significant increases in exercise. Significant improvements in BMI, self-efficacy, and body satisfaction were found in only The Coach Approach–supplemented: Small Groups class. Psychosocial changes predicted increased exercise. Self-regulation was the strongest contributor. Conclusions: Overall, results were positive and warrant more comprehensive testing.     

Effects of Pilates method in physical fitness on older adults. A systematic review

Pilates method is employed for physical and mental conditioning. Elderly people could be benefited from a patterned and regulated conditioning work based on Pilates method. We performed a systematic review to assess the evidence on the effects of Pilates method in physical fitness on older adults. Our search included the following databases: MEDLINE-PubMed, Scopus and CINAHL Plus with Full Text via EBSCO and SPORTDiscus databases (up to April 2014). A summary of the results was performed using a best evidence synthesis and was reported according to the systematic review method proposed by Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) statement. The Physiotherapy Evidence Database (PEDro) scale was used to assess the methodology quality of selected studies. Seventeen experimental studies were included in this review. Fourteen were randomized controlled trials (RCT) and three clinical controlled trials (CCT). Quality scores according to PEDro indicate low quality of the included studies (range 1–6, mean 3.8?±?1.2). The most studied components related to physical fitness were neuromotor fitness (n?=?11), muscle strength (n?=?8), cardiorespiratory endurance (n?=?4), body composition (n?=?4) and flexibility (n?=?4). Results indicate that Pilates method seems to present positive effects in neuromotor fitness, especially in static and dynamic balance. Related to the other components of physical fitness (cardiorespiratory endurance, muscle strength, body composition and flexibility), contradictory results were observed. The Pilates method indicates to be an appropriate exercise modality in order to improve balance on older adults. Nevertheless, more intervention research is needed to build a solid knowledge base about the health benefits of Pilates method on older people, especially regarding the other components of physical fitness.     

Assessing overweight, obesity, diet, and physical activity in college students

The authors surveyed 738 college students aged 18 to 27 years to assess overweight, obesity, dietary habits, and physical activity. They used BMI (body mass index) > or = 25 kg/m2 or BMI > or = 85th percentile and BMI > or = 30 kg/m2 or BMI > or = 95th percentile to estimate overweight and obesity in those aged < or = 19 years. To define overweight and obesity in those > or = 20 years, they used BMI > or = 25 kg/m2 and > or = 30 kg/m2. They found overweight rates of 21.6% using BMI directly and 16.2% using BMI percentile and obesity rates of 4.9% using BMI directly and 4.2% using BMI percentile. More than 69% of the participants reported < 5 servings of fruits and vegetables per day and more than 67% reported < 20 g of fiber per day; participants reported physical activity on fewer than 3 d/wk. Most college students are not meeting dietary and physical activity guidelines, suggesting the need for prevention interventions and increased understanding of overweight in college students.     

Level of physical activity and anthropometric characteristics in old age—results from a national health survey

Advanced age is associated with degenerative changes in body composition. There is evidence suggesting that changes may vary upon differences in lifestyle, environment, or gender. Physical activity engagement is considered an important component of lifestyle definition. There are suggestions that engaging in physical activity might alleviate degenerative body compositional changes. The objective is to assess the relationship between adherence to recommended guidelines of physical activity and anthropometric parameters in Israeli older adults. Anthropometric measures, including height, weight, and waist circumference, were taken, and BMI was calculated, from a random sample of 1,663 elderly adults (799 men and 864 women), aged 74.31 (±6.05) years old. Participants reported their physical activity habits and, based on official guidelines recommendations, they were divided into sufficiently active, insufficiently active, and inactive groups. One-way ANOVA (level of physical activity) for both genders was conducted for each anthropometric variable. In both genders, an association between level of physical activity and weight, waist circumference, and BMI was found, with lower values among the sufficiently active. In addition, a relationship between level of physical activity and height was indicated among women, implying that the more active women were taller than the less active. In addition to the already known health benefits of physical activity in old age, it is possible that adherence to recommended guidelines of physical activity is associated with favorable anthropometric characteristics.     

Moderators of the Relationship Between Physical Activity and Alcohol Consumption in College Students

Abstract

Objective: Among college students, several studies have found a positive relationship between physical activity and alcohol use. The current study tested gender, Greek status, and ethnicity as potential moderators of the physical activity-alcohol use relationship. Participants: Participants were college freshmen (n = 310) endorsing alcohol/drug use. Methods: Students completed questionnaires assessing a number of health behaviors. Results: Results indicated that gender and Greek status were significant moderators of the relationship between physical activity and alcohol consumption. There was a positive relationship between physical activity and alcohol use for men and Greeks, but not for females and non-Greeks. Conclusions: These findings suggest that exercise does not serve as a protective factor for any of the subgroups of college students studied and is positively associated with drinking among college students who are men and/or involved with the Greek system.     

Predictors of late adolescent delinquency: The protective role of after-school activities in low-income families

Research suggests an important link between maternal welfare and employment, lack of after-school care, and a child's propensity to engage in increased levels of delinquency. Indeed, with welfare reform, many disadvantaged families, typically single-mother households, face increased pressures to move off of welfare and into employment or risk losing their benefits, which decreases the mother's ability to provide adequate after-school care and supervision. Using longitudinal data from Welfare, Children, and Families: A Three-City Study, this study assessed how changes in maternal welfare and employment status, as well as participation in after-school activities influence rates of adolescents' delinquency 4 years later. Results show that early and increased participation in after-school activities served as a protective factor against late adolescent delinquency during a mother's transition off of welfare. Youth who increased their after-school activity participation from early to late adolescence had lower rates of delinquency at wave 3. Policy implications are discussed.     

The effect of three different exercise training modalities on cognitive and physical function in a healthy older population

Background

Older adults are encouraged to participate in regular physical activity to counter the age-related declines in physical and cognitive health. Literature on the effect of different exercise training modalities (aerobic vs resistance) on these health-related outcomes is not only sparse, but results are inconsistent. In general, it is believed that exercise has a positive effect on executive cognitive function, possibly because of the physiological adaptations through increases in fitness. Indications are that high-intensity interval training is a potent stimulus to improve cardiovascular fitness, even in older adults; however, its effect on cognitive function has not been studied before.Therefore, the purpose of this study was to compare the effects of resistance training, high-intensity aerobic interval training and moderate continuous aerobic training on the cognitive and physical functioning of healthy older adults.

Methods

Sixty-seven inactive individuals (55 to 75 years) were randomly assigned to a resistance training (RT) group (n = 22), high-intensity aerobic interval training (HIIT) group (n = 13), moderate continuous aerobic training (MCT) group (n = 13) and a control (CON) group (n = 19) for a period of 16 weeks. Cognitive function was assessed with a Stroop task and physical function with the Timed-Up-and-Go (TUG) and submaximal Bruce treadmill tests.

Results

No significant GROUP x TIME interaction was found for Stroop reaction time (P > .05). The HIIT group showed the greatest practical significant improvement in reaction time on the information processing task, i.e. Stroop Neutral (ES = 1.11). MCT group participants had very large practical significant improvements in reaction time on the executive cognitive tasks, i.e. Stroop Incongruent and Interference (ES = 1.28 and 1.31, respectively). The HIIT group showed the largest practically significant increase in measures of physical function, i.e. walking endurance (ES = 0.91) and functional mobility (ES = 0.36).

Conclusions

MCT and RT proved to be superior to HIIT for the enhancement of older individuals’ executive cognitive function; whereas HIIT were most beneficial for improvement in information processing speed. HIIT also induced the largest gains in physical function.

     

Impact of physical activity and sedentary behaviour on fall risks in older people: a systematic review and meta-analysis of observational studies

The objective of this work was to summarise and evaluate the evidence showing that physical activity is a protector factor as regards falls in older people. Relevant studies were identified through a systematic search in the MEDLINE and Cochrane Library, under the keywords of accidental fall/numerical data and risk factors, and with the bibliographies of retrieved papers. The combined odds ratio (OR) [95% confidence interval] for physical activity was 0.75 [0.64, 0.88] with moderate heterogeneity (I ²?=?33%). For fall injury, it was 0.59 [0.47, 0.74] and, for falls in general, it rose to 0.94 [0.76, 1.17] with nil heterogeneity. The combined OR for sedentary factors was 1.14 [1.10, 1.82] with moderate heterogeneity (I ²?=?36%). Regular physical activity in daily life yields significant reduction in falls in older people, especially falls with injuries.     

Age influences anthropometric and fitness-related predictors of bone mineral in men

Objective. This study assessed the influence of age on the predictors of bone mineral in men.

Methods. Middle-age (n = 41, 54 ± 4 yrs) and older (n = 40, 69 ± 5 yrs) men underwent grip and knee extensor strength tests, total body dual-energy X-ray absorptiometry with regional analyses and a graded exercise treadmill test.

Results. Bone-free lean mass (BFLM) and, to a lesser extent, fat mass (FM) were correlated with bone mineral variables in middle-age men. In older men, BFLM and, to a lesser extent, FM were related to bone mineral content (BMC) at most sites, but inconsistently to bone mineral density (BMD). Knee extensor strength related to bone mineral (BMC and BMD) at most sites in middle-age men, but none in older men. Grip strength inconsistently related to bone mineral in both groups. Aerobic capacity related to bone mineral in middle-age men, but none in older men. In multiple regression, body weight or BFLM predicted bone mineral in middle-age men (R² = 0.33–0.68) and BMC in older men (R² = 0.33–0.50). Predictors of BMD were inconsistent in older men.

Conclusions. Relationships of body composition, muscular strength and aerobic capacity to bone mineral are stronger in middle-age versus older men.     

The Influence of Consent on College Students’ Perceptions of the Quality of Sexual Intercourse at Last Event

ABSTRACT. The current study assessed consent's relation to quality of sexual intercourse. College students (n = 640) participated in a survey assessing their most recent intercourse. Hierarchical regression was conducted: alcohol consumption, relationship status, and age were entered in Step 1; the Internal and External Consent Scale factors were entered in Step 2. For women, three internal consent factors explained a significant proportion of variance in quality of intercourse beyond Step 1 (ΔR² = .17, p < .001). For men, one internal and two external consent factors were significant predictors beyond Step 1 (ΔR² = .24, p < .001). Preliminary findings suggest consent is associated with quality of intercourse.     

Campus Walkability,Pedometer-Determined Steps,and Moderate-to-Vigorous Physical Activity: A Comparison of 2 University Campuses

Objective and Participants: At 2 Arizona State University (ASU) campuses, the authors measured student activity and distance walked on campus, as well as student-reported walkability around the student union. Methods: Students from ASU-Polytechnic (n = 20, 33% male) and ASU-Tempe (n = 20, 60% male) recorded distance walked on campus and wore physical activity monitors for 5 days. Results: Polytechnic students spent an average of 36.9 minutes in moderate-to-vigorous physical activity each week; Tempe students spent 69.5 minutes (p < .001). At Polytechnic, students walked an average of 7,674 steps per weekday; at Tempe, 11,294 steps (p = .003). Female students at Polytechnic walked an average of 1.3 km/d; at Tempe, 4.3 km/d (p < .001). At Polytechnic, men walked an average of 1.4 km/d; at Tempe, 3.1 km/d (p = .03). Tempe students rated campus walk-ability as very good, whereas Polytechnic students rated it fair (p < .001). Conclusions: Students at both campuses met activity recommendations; noted differences may be attributed to the built environment's contribution to walkability.     

Stages of Change Among Ethnically Diverse College Students

Abstract

The authors applied the stage-of-change construct in the transtheoretical model to examine the distribution of Asian (n = 869), African American (n = 373), White (n = 1322), and Hispanic (n = 535) American undergraduate students across the 5 stages of change for exercise. Stage of change varied as a function of ethnicity. Higher percentages of minorities were in the precontemplation and contemplation stages. The likelihood of being in these stages was from 43% to 82% greater for minorities than for White students. Also examined were the congruency between stage of change and self-reported levels of physical activity. Half of the sedentary students and 15.6% of the active students were misclassified by the stage-of-change procedure. Misclassification rates were higher for minority women (27.8%) than for White women (17.8%) and for Asian students (24.6%) compared with all others (20.6%). The results of this study have implications for the design of physical activity interventions based on stage of change.     

Risk in childhood family environments and loneliness in college students: Implications for health

Abstract

Objective: To investigate associations between risk in family environments and health-relevant outcomes in college and the role of loneliness. Participants: College students at a state university (N?=?360). Methods: We utilized linear regression to examine relationships between risk in family environments and loneliness, perceived stress, affect, and self-rated health. We tested for indirect effects of risk in family environments on outcomes through loneliness Results: Analyses showed that risk in family environments associated with loneliness (β?=?0.12 t[358]?=?2.22, p = .03, R² change = .02), perceived social stress (β?=?0.20, t[357]?=?3.88, p?<?0.001, R² change = .04), negative and positive affect (β?=?2.44, t[357]?=?3.95, p < .001, R² change = .04), and (β = –0.18 t[357]= –3.44, p = .001, R² change = .03 respectively), and self-rated health (β?=?0.19, t[359]?=?4.57, p < .001, R² change = .10). Significant indirect effects were observed for risk in early family on all outcomes through loneliness. Conclusion: These findings provide initial evidence that risk in childhood family environments may negatively affect health by increasing loneliness in college students.     

A Report on Student Health Services

Abstract

Objective: Stress impacts college students, faculty, and staff alike. Although meditation has been found to decrease stress, it is an underutilized strategy. This study used the Reasoned Action Approach (RAA) to identify beliefs underlying university constituents’ decision to meditate. Participants: N = 96 students, faculty, and staff at a large midwestern university during spring 2012. Methods: A survey measured the RAA global constructs and elicited the beliefs underlying intention to meditate. Thematic and frequency analyses and multiple regression were performed. Results: Quantitative analyses showed that intention to meditate was significantly predicted (R² = .632) by attitude, perceived norm, and perceived behavioral control. Qualitative analyses revealed advantages (eg, reduced stress; feeling calmer), disadvantages (eg, takes time; will not work), and facilitating circumstances (eg, having more time; having quiet space) of meditating. Conclusions: Results of this theory-based research suggest how college health professionals can encourage meditation practice through individual, interpersonal, and environmental interventions.     

A randomized,double-blind,placebo-controlled trial of testosterone gel on body composition and health-related quality-of-life in men with hypogonadal to low-normal levels of serum testosterone and symptoms of androgen deficiency over 6 months with 12 months open-label follow-up

Introduction: The clinical significance of low to low-normal testosterone (T) levels in men remains debated. Aim: To analyze the effects of raising serum T on lean body mass (LBM), fat mass (FM), total body mass, and health-related quality-of-life (HRQoL). Methods: Randomized, double-blind, placebo-controlled study. Men, aged 50–80 years, with serum total T<15 nmol/L and bioavailable T < 6.68 nmol/L, and a Aging Males’ Symptoms (AMS) total score >36, received 6 months treatment with transdermal 1% T gel (5–7.5?mg/day; n =183) or placebo gel (n =179), followed by 12 months open-label with T in all. Results: After 6 months, LBM increased in T- treated patients by 1.28?±?0.15?kg (mean ± SE) and FM decreased by 1.16?±?0.16?kg, with minor changes with placebo (LBM +0.02?±?0.10?kg and FM ?0.14?±?0.12?kg; all p < 0.001, T group vs. placebo). Changes were largely similar across subgroups of age, baseline total testosterone, and baseline BMI. Total HRQoL improved compared with placebo (p < 0.05, T group vs. placebo). Conclusions: Six months 1% T gel improved body composition and HRQoL in symptomatic men with low to low-normal T, with further improvements over the following 12 months.     

Body Size and Sexual Behavior in a Community-Based Sample of Women

ABSTRACT. Women's body size is closely related to their social and sexual experiences. Clinical research has found that women's lifetime sexual behaviors may vary based on body mass index (BMI). Objectives: This study examined the relationship between BMI and recent solo and partnered sexual repertoire in a community-based, non-clinical sample of women. Methods: Two hundred thirty-eight sexually active women completed an online survey measuring age, sexual relationship status, BMI, gender of sexual partners, and engagement in sexual behaviors in the previous 4 weeks. Logistic regression analyses were conducted to determine whether BMI predicted engagement in behaviors after controlling for age and sexual relationship variables. Results: Participant age ranged from 18 to 56 years (M = 30.4, SD = 7.8). Participants were predominantly in exclusive sexual relationships (62.9%, n = 146) with men (82.8%, n = 197). Mean BMI for the sample was 29.33 (SD = 9.28). Participation in self-masturbation, masturbating a partner, performing oral sex on a partner, receiving oral sex from a partner, and penile–vaginal intercourse were not predicted by BMI after controlling for age and partner variables. Conclusions: BMI did not impact sexual repertoire during the previous 4 weeks, with the exception of an increased odds ratio for penile–anal intercourse (OR = 1.06; 95% CI [1.02, 1.10]). Researchers and practitioners working with women should not assume limitations on women's sexual repertoires because of larger body size.     

Does the medium matter? A meta-analysis on using social media vs. traditional media in crisis communication

There has been a growing body of crisis communication research that treats social media as a critical variable, which might alter how people perceive and react to crisis communication messages. The meta-analysis of 8 studies (k = 22, n = 3209, combined n = 9703) compared the impact of social media vs. traditional media in crisis communication. Five studies (n = 1896) contained 8 relevant effect sizes on crisis responsibility, representing 3294 individuals. Seven studies (n = 3185) contained 14 relevant effect sizes on persuasiveness, representing 6409 individuals. Compared to traditional media, using social media significantly lessened consumers’ perceived crisis responsibility (r = -.134, 95 % CI -.212– -.054, p = .001). There was no significant difference between using traditional media and social media in crisis communication on persuasiveness (r = -.039, 95 % CI -.114– .035, p = .30). The moderator analysis indicated that for both crisis responsibility and persuasiveness, the effect size was more noticeable when an organization communicates with college students vs. non-student publics. The ability of social media in dampening crisis responsibility was more pronounced for fictitious organizations compared to real organizations. Compared to traditional media, social media was significantly more negative for preventable crisis, the influence was weak for accidental crisis. Theoretical and practical implications are discussed, as well as directions for future research.
