Men are increasingly turning to dermatologists and plastic surgeons to request procedures that correct or enhance physical features. With the advent of this emerging new patient population, alterations in preexisting aesthetic techniques, gender-specific uses of existing devices and overall approaches need to be revisited and adapted to obtain results that are suitable for the male patient. Recently, body contouring has become one of the most sought out procedures by men. Although the majority of clinical studies involving body contouring esthetics are performed with female patients, gains from such studies can be extrapolated to men. Body contouring can be broadly classified as non-invasive or invasive, depending on the modality used. Non-invasive contouring is most frequently performed with devices that target subcutaneous adipose with focused electrical or thermal energy, including low-level laser, cryolipolysis, ultrasonography, and radiofrequency. Invasive body contouring modalities useful for male body contouring include liposuction, pectoral and abdominal wall etching, jawline fillers, synthetic deoxycholic acid injections, and solid silicone implants. The purpose of this review is to bring attention to the unique aspects, strategies, and modalities used in aesthetic body contouring for the male patient.

Research examining the impact on adolescent boys of exposure to muscular, athletic, idealised male images has been limited. This research had two aims (i) to investigate the mean effect on state body satisfaction and mood of exposure to idealised male images in adolescent boys, and, (ii) to identify individual attributes that predicted change in state body satisfaction, depression and anxiety following image exposure. One hundred and six boys (mean age=15.6 years) completed a self-report questionnaire on body image attitudes and psychological status. One week later, participants were divided into two groups, one that viewed idealised male images (experimental condition) while the other viewed non-figure advertising images (control condition). Three body satisfaction Visual Analogue Scale (VAS), and a depression and anxiety VAS were completed immediately prior to and following image exposure. In the experimental compared to control condition, there were no significant changes on Want Toned Body, Want to Change Body Shape, Depression and Anxiety VAS following image exposure. However, there was a significant improvement in Like Body Shape VAS. In the experimental group, high internalisation of the muscular, athletic ideal predicted more negative response to viewing images on the body image and Depression VAS. Prior body dissatisfaction significantly predicted negative response to Body Shape Liking and Anxiety VAS. While on average, adolescent boys in this research were not negatively affected by exposure to idealised male images, reaction to exposure is dependent on individual attributes.

Full Text Available Background The study of male body image has increased substantially, but there are few assessment tools available for this population. The Male Body Dissatisfaction Scale (MBDS has been widely used among students to research body image disturbances and eating disorders. However, the psychometric properties of this instrument have not been tested in the Brazilian context.Objectives To explore the psychometric properties (convergent validity, internal consistency, test-retest reliability and factor structure of the Brazilian version of the MBDS.Methods Two-hundred sixty-four undergraduate students were evaluated. Pearson’s correlation was used to test the convergent validity of the MBDS and the Drive for Muscularity Scale, the Swansea Muscularity Attitudes Questionnaire, the Rosenberg Self-Esteem Scale, the Beck Depression Inventory, the Eating Attitudes Test-26, and the Commitment to Exercise Scale. Test-retest reliability was evaluated using t-tests for repeated measures and by calculating the coefficient of intraclass correlation. Exploratory factor analysis was conducted, and Cronbach’s α coefficients were determined. A significance level of 5% was adopted.Results The MBDS had an adequate factor structure, with two factors explaining 52.67% of the total variance. It showed excellent internal consistency (Cronbach’s α between 0.90 and 0.92, a high intraclass correlation coefficient (0.81, and convergent validity with the drive for muscularity, the psychological commitment to exercise, low self-esteem, and eating disorder risk behaviour measures.Discussion The MBDS appears to be a valid and reliable tool for evaluating Brazilian male body image dissatisfaction.

Full Text Available Objective: To identify disordered eating behaviors and body image dissatisfaction, as well as their relationship to body fat (BF, among male athletes in high risk sports for eating disorders. Methods: One hundred and fifty-six male athletes were divided into the following categories: weight-class sports, sports where leanness improves performance, and sports with aesthetic ideals. BF was assessed and three questionnaires were used: the Eating Attitudes Test; the Bulimic Investigatory Test, Edinburgh; the Body Shape Questionnaire. Results: Disordered eating behaviors and body image dissatisfaction were found in 43 (27.6% and 23 athletes (14.7%, respectively, and an association was detected between the two variables (p < 0.001. Athletes with and without disordered eating behaviors did not differ in %BF (11.0±5.2% and 9.8±4.0%, respectively; p = 0.106. However, athletes with body image dissatisfaction had higher %BF than those who were satisfied (12.6±5.9% and 9.7±3.9%, respectively; p = 0.034. There were no differences in BF, frequency of disordered eating behaviors, and body image dissatisfaction between sports categories. Conclusion: Nearly one-quarter of athletes showed disordered eating behaviors, which was associated with body image dissatisfaction. Athletes with higher %BF were more likely to be dissatisfied with body image. There was no difference in eating behavior and body image between athletes from different sports categories.

It is well documented that anti-fat attitudes influence the interactions individuals have with overweight people. However, testing attitudes through self-report measures is challenging. In the present study, we explore the use of a haptic virtual reality environment to physically interact with overweight virtual human (VH). We verify the hypothesis that duration and strength of virtual touch vary according to the characteristics of VH in ways similar to those encountered from interaction with real people in anti-fat attitude studies. A group of 61 participants were randomly assigned to one of the experimental conditions involving giving a virtual hug to a female or a male VH of either normal or overweight. We found significant associations between body image satisfaction and anti-fat attitudes and sex differences on these measures. We also found a significant interaction effect of the sex of the participants, sex of the VH, and the body size of the VH. Female participants hugged longer the overweight female VH than overweight male VH. Male participants hugged longer the normal-weight VH than the overweight VH. We conclude that virtual touch is a promising method of measuring attitudes, emotion and social interactions.

This study examined preferences for masculinity across faces, bodies, and personality traits in 462 homosexual and bisexual men in China. The impact of sexual self-labels (tops, bottoms, and versatiles) and attitude toward male masculinity on preferences for masculinity were also examined. Participants were asked to select the seven most desirable personality traits for a romantic partner from a list of 32 traits of gender roles. A series of 10 masculinized and feminized dimorphic images of male faces and bodies were then presented to participants, who were required to identify their preferred image. The results indicated that participants preferred more masculine faces, bodies, and personality traits. Significant differences in preferences for masculinity were found between tops, bottoms, and versatiles, with both bottoms and versatiles preferring more masculine faces, bodies, and personality traits than did tops. In addition, preferences for masculinity across faces, bodies, and traits showed a significant positive correlation with each other for all sexual self-labels, indicating a consistent preference for masculinity. Attitude toward male masculinity was significantly correlated with facial, body, and trait preferences; individuals with more rigid attitudes toward male masculinity (low acceptance of femininity in males) preferred more masculine characters. These results indicate a consistent preference for masculinity between both physical features (faces and bodies) and personality traits (instrumentality) that may be affected by observer perception.

Background: The recent and rapidly popularized social phenomenon of selfie taking has been showing an increasing trend. It is thus imperative to assess the knowledge, attitude, and perception of the groups toward this phenomenon. Selfie taking is associated with younger age groups and hence, we aimed to explore the attitudes toward selfie taking and its relation toward body image and narcissism in medical college students. Methodology: This was cross-sectional study and had two groups with Group A comprising 92 first year medical students and Group B including 103 postgraduate (PG) medical students from various specialties. They were interviewed in a single session using the scale of attitude toward selfie-taking questionnaire, Body Image Acceptance and Action Questionnaire (BIAAQ), and the narcissistic personality inventory. Scores obtained were computed using basic descriptive statistics and t-test where appropriate. Results: A strong positive favorable trend toward selfie taking was noticed among both groups (A = 56.5%, B = 45.6%). There was no difference in attitude between the two groups, or difference in the gender between those clicking their own selfies regularly within each group. BIAAQ reflected a significant difference among male subjects of the two groups with PG students was more concerned about body image (P = 0.001), whereas female subjects of both groups showed no such difference. The narcissism traits also showed a significant difference, only when males of both groups were compared again in favor of PG medical students (P = 0.022). Conclusion: This study revealed that selfie-taking is popular among medical students both in their undergraduate and PG period. Further research in diverse clinical and nonclinical populations is warranted to explore the relation between this phenomenon and body image acceptance or narcissistic traits. PMID:29403124

This study examined the body composition, nutritional knowledge, behaviors, attitudes, and educational needs of senior schoolboy rugby players in Ireland. Participants included 203 male rugby players age 15-18 yr competing at Senior School's Cup level in Leinster, Ireland. Estimation of body composition included measurement of height, weight, and percentage body fat (PBF; using bioelectrical impedance analysis, Tanita BC-418). Nutritional knowledge, behaviors, attitudes, and education needs were assessed by questionnaire. The range of PBF was 5.1-25.3%. Sixty-eight percent of the players in this study had a healthy PBF (10-20%), 32 (22%) were classified as underweight (benefit from appropriate nutritional education.

The purpose of this study was to assess (a) similarities in self-reported bar-aggression-related attitudes and behaviors among members of young male groups recruited on their way to bars and (b) group-level variables associated with individual members' self-reported likelihood of perpetrating physical bar aggression in the past year, controlling for individual attitudes. Young, male, natural drinking groups recruited on their way to a bar district Thursday, Friday, and Saturday nights (n = 167, 53 groups) completed an online survey that measured whether they had perpetrated physical aggression at a bar in the past year and constructs associated with bar aggression, including attitudes toward male bar aggression and frequency of heavy episodic drinking in the past year. Intraclass correlations and chi-square tests demonstrated significant within-group similarity on bar-aggression-related attitudes and behaviors (ps bar aggression were significantly associated with individuals' likelihood of perpetrating physical bar aggression, controlling for individual attitudes (p bar aggression was nonsignificant in the full model. This study suggests that the most important group influence on young men's bar aggression is the attitudes of other group members. These attitudes were associated with group members' likelihood of engaging in bar aggression over and above individuals' own attitudes. A better understanding of how group attitudes and behavior affect the behavior of individual group members is needed to inform aggression-prevention programming.

Many young men continue to disregard the importance of contraception and family planning in South Africa. The fact that even university students also do not take contraception and family planning seriously poses a serious threat to their own health and well-being. This paper aims at investigating the attitudes of male students towards contraception and the promotion of female students' sexual health rights and well-being at the University of Venda. Quantitative research method is used to determine how attitudes of 60 male students towards contraception can jeopardise the health and well-being of both male and female students. This study reveals that the majority of 60 male students at the University of Venda have a negative attitude towards contraceptives. As a result, male students at the University of Venda are not keen on using contraceptives. Male students' negative attitude and lack of interest in contraceptives and family planning also limit progress in achieving the Millennium Development Goals on primary health care, especially with regard to sexual and reproductive health and well-being of female students at the University of Venda. The fact that more than half of the male students interviewed did not take contraception and family planning seriously poses a serious threat to health and well-being of students, including violation of female students' sexual and reproductive health rights in South Africa. This calls for radical health promotion and sexual and reproductive rights programmes which should specifically target male students at the University of Venda.

Furnham, Adrian; Badmin, Nicola; Sneade, Ian

2002-11-01

Two hundred and thirty-five adolescents completed a questionnaire on the subject of eating attitudes, self-esteem, reasons for exercise, and their ideal versus current body size and shape. As predicted, boys were as likely to want to be heavier as lighter, whereas very few girls desired to be heavier. Only girls associated body dissatisfaction with the concept of self-esteem. Male self-esteem was not affected by body dissatisfaction. Specific reasons for exercise were found to correlate with low self-esteem and disordered eating, regardless of sex. The results are discussed in relation to burgeoning published research in this area.

Do depression, self-esteem, body-esteem, and eating attitudes vary by BMI among African American adolescents?

2013-11-01

To examine how psychosocial factors vary by body weight and gender among African-American adolescents. A community sample of 235 low-income, predominantly African-American adolescents completed measures of depression, self-esteem, body-esteem, and eating attitudes. Measured weight and height were converted to body mass index (kg/m(2)) age and gender-adjusted z-scores. Data were analyzed using 2-factor multivariate analysis of variance. Obese youths had significantly worse scores on all psychosocial domains than normal weight youths, with no differences between overweight and normal weight youths. Obese youths had significantly worse scores than overweight youths on body-esteem and self-esteem. Female adolescents had significantly worse scores than males on depressed mood, body-esteem, and eating attitudes. Among a community sample of predominantly African-American adolescents, obesity, not overweight, was associated with poor psychosocial health. Findings suggest that overweight may be perceived as normative, and that weight-related programs consider adolescents' psychosocial functioning.

Many wrestlers engage in chronic dieting and rapid "weight cutting" throughout the year to compete in a category below their natural weight. Such weight-management practices have a negative influence on their health and nutritional status, so the National Wrestling Coaches Association implemented a new weight-management program for high school wrestlers in 2006. The purpose of this study was to determine whether seasonal changes in weight, body fat, and eating attitudes occur among high school wrestlers after the implementation of the new weight-management rule. Fifteen high school wrestlers participated in the study. Their weight, body composition, and eating attitudes were measured preseason, in-season, and off-season. Body fat was assessed using dual-energy X-ray absorptiometry. Attitudes toward dieting, food, and body weight were assessed using the Eating Attitude Test (EAT). No significant changes in body fat were detected from preseason to off-season. Weight increased from preseason to in-season (p < .05) and off-season (p < .05). Although the EAT score did not change significantly from preseason to off-season, 60% reported "thinking about burning up calories when exercising" during preseason, and only 40% felt that way during the season (p < .05) and 47% during, off-season (p < .05). The wrestlers experienced a significant weight gain from preseason to off-season with no significant changes in body fat. Their eating attitudes did not change significantly from preseason to off-season in this study, but further research using a large sample of high school wrestlers is warranted to confirm these findings.

1977-01-01

Male attitudes toward family planning education were assessed through a study of 720 men in Santiago and 240 men in a nearby rural area of Chile. Interviews were conducted by male students at the University of Chile School of Public Health. A large majority of the men were using or planned to use contraception in the future. There was a near consensus that adults should be informed regarding family planning. More than a majority of the respondents favored provision of contraceptive information for unmarried women, but most did not approve of premarital sexual activity for females. Most respondents favored the teaching of sex education in schools "according to the age of the children." Younger and higher class males tended to hold the most liberal attitudes.

The scope of this study was to analyze the relationship between the internalization of body image and depressive symptoms with restrictive eating habits among young males. Three hundred and eighty-three male adolescents, aged between twelve and seventeen, took part in this survey. The "Overall Internalization" and "Athletic Internalization" sub-scales taken from the Sociocultural Attitudes Towards Appearance Questionnaire-3 (SATAQ-3) were used to evaluate the internalization of body images. The Major Depression Inventory (MDI) was used to evaluate depressive symptoms. The "Diet" sub-scale from the Eating Attitudes Test (EAT-26) was used to evaluate restrictive eating habits. The logistic regression findings indicated 2.01 times greater chances of youngsters with a high level of overall internalization adopting restrictive eating habits (Wald = 6.16; p = 0.01) when compared with those with low levels. On the other hand, the regression model found no significant association between "Athletic Internalization" (Wald = 1.16; p = 0.23) and depressive symptoms (Wald = 0.81; p = 0.35) with eating restrictions. The findings made it possible to conclude that only overall internalization was related to eating restrictions among young males.

The growing commercial value of the male body: a longitudinal survey of advertising in women's magazines.

2001-01-01

With the advances of feminism, men have gradually relinquished their once-exclusive 'masculine' roles as fighters and breadwinners. In response to this change, the male body may have gained in relative importance as one of the few surviving marks of masculinity. We hypothesized that these trends might be quantified by using a commercial measure such as advertising. We examined the proportion of exposed male and female bodies portrayed in advertisements between 1958 and 1998 in two leading American women's magazines. In both magazines, the proportion of undressed women in the advertisements has changed little over the last 40 years, whereas the proportion of undressed men has increased dramatically, especially since the early 1980s. Trends in commercial advertising offer tentative support for the hypothesis that the male body is increasing in importance as a mark of masculinity--at least as judged from the actions of advertisers seeking to influence women's attitudes.

This study examined the role of media body comparison as a mediator of the relationships between psychological factors and sociocultural pressures to be thin and body dissatisfaction in both females and males. Participants were 1,386 females (mean age = 19.37 years) and 1,130 males (mean age = 19.46) from diverse backgrounds who completed a self-report questionnaire. Path analysis was used to test a cross-sectional model in which media body comparison mediated the impact of self-esteem, depressive mood, parent dieting environment, friend dieting, TV exposure, magazine message exposure, weight teasing and body mass index (BMI) on body dissatisfaction. In females, media body comparison partially or fully mediated relationships between self-esteem, depressive mood, friend dieting, magazine message exposure and BMI, and body dissatisfaction. In males, media body comparison was not a significant predictor of body dissatisfaction. This research particularly highlights the need to further examine processes that are involved in the development of body dissatisfaction in males.

Sneaker Males Affect Fighter Male Body Size and Sexual Size Dimorphism in Salmon.

Weir, Laura K; Kindsvater, Holly K; Young, Kyle A; Reynolds, John D

2016-08-01

Large male body size is typically favored by directional sexual selection through competition for mates. However, alternative male life-history phenotypes, such as "sneakers," should decrease the strength of sexual selection acting on body size of large "fighter" males. We tested this prediction with salmon species; in southern populations, where sneakers are common, fighter males should be smaller than in northern populations, where sneakers are rare, leading to geographical clines in sexual size dimorphism (SSD). Consistent with our prediction, fighter male body size and SSD (fighter male∶female size) increase with latitude in species with sneaker males (Atlantic salmon Salmo salar and masu salmon Oncorhynchus masou) but not in species without sneakers (chum salmon Oncorhynchus keta and pink salmon Oncorhynchus gorbuscha). This is the first evidence that sneaker males affect SSD across populations and species, and it suggests that alternative male mating strategies may shape the evolution of body size.

Orbit-attitude coupled motion around small bodies: Sun-synchronous orbits with Sun-tracking attitude motion

Science.gov (United States)

Kikuchi, Shota; Howell, Kathleen C.; Tsuda, Yuichi; Kawaguchi, Jun'ichiro

2017-11-01

The motion of a spacecraft in proximity to a small body is significantly perturbed due to its irregular gravity field and solar radiation pressure. In such a strongly perturbed environment, the coupling effect of the orbital and attitude motions exerts a large influence that cannot be neglected. However, natural orbit-attitude coupled dynamics around small bodies that are stationary in both orbital and attitude motions have yet to be observed. The present study therefore investigates natural coupled motion that involves both a Sun-synchronous orbit and Sun-tracking attitude motion. This orbit-attitude coupled motion enables a spacecraft to maintain its orbital geometry and attitude state with respect to the Sun without requiring active control. Therefore, the proposed method can reduce the use of an orbit and attitude control system. This paper first presents analytical conditions to achieve Sun-synchronous orbits and Sun-tracking attitude motion. These analytical solutions are then numerically propagated based on non-linear coupled orbit-attitude equations of motion. Consequently, the possibility of implementing Sun-synchronous orbits with Sun-tracking attitude motion is demonstrated.

Attitudes Toward Gender, Work, and Family among Female and Male Scientists in Germany and the United States

Science.gov (United States)

Hanson, Sandra L.; Fuchs, Stefan; Aisenbrey, Silke; Kravets, Natalyia

This research used a comparative approach and an elite framework to look at attitudes toward gender, work, and family among male and female scientists. The data came from the 1994 International Social Survey Program module measuring family and changing gender roles in (the former) East Germany, West Germany, and the United States. Research questions focused on the variation between the three samples in male scientists' attitudes regarding gender, work, and family; women's representation in science occupations; and the relation between the two. Another major concern was the extent to which female scientists express attitudes regarding gender, work, and family that resemble those of male scientists and the implications of these processes for increasing women's access to science. As predicted, male scientists in East Germany tended to have the most progressive attitudes (especially those regarding gender and work), East German women had the greatest access to science occupations, and there were virtually no sex differences in attitudes of East German scientists. West German male scientists were the most traditional on attitudes regarding gender and work, and U. S. male scientists tended to be the most traditional on attitudes regarding family. The attitudes of female scientists in West Germany and the United States reflected this larger trend, but there were sex differences within countries, with female scientists being more progressive than male scientists. Thus, the findings suggest that women s representation in science is related to the attitudes of male scientists regarding gender, work, and family. And although female scientists often hold quite similar attitudes as male scientists, there is considerable cross-country variation in how progressive the attitudes are and how similar men's and women's attitudes are. Implications for women's access to elite science occupations are discussed.

To describe the knowledge, attitudes, and practices of young adults toward body piercing. An anonymous 30-item survey was given to 103 undergraduate students at the campus health service of a large urban university. The questionnaire collected data on students' perceptions regarding the social acceptability of body piercing, their experiences with and attitudes toward this form of body art, and their knowledge of associated health risks. One hundred (97%) out of the 103 surveys distributed had sufficient data for analysis. Fifty-six percent of participants (age range, 17 to 25 years) reported having a body piercing at one time. Participants with a piercing were more likely to have a tattoo (OR, 4.13; 95% CI, 1.10-15.56; P=.04). The majority of participants (65 [78%]) reported "liking" body piercing on others, though a smaller percentage (45 [52%]) reported "liking" it on themselves (z=3.58, Part is acceptable on others, they feel it is less acceptable on themselves. Study participants displayed a high level of awareness regarding the potential health risks of body art, and, in fact, overestimate those risks. Implications for patient education are addressed.

Wat, Heidi; Wu, Douglas C; Goldman, Mitchel P

2018-01-01

Noninvasive body contouring is an attractive therapeutic modality to enhance the ideal male physique. Men place higher value on enhancing a well-defined, strong, masculine jawline and developing a V-shaped taper through the upper body. An understanding of the body contour men strive for allows the treating physician to focus on areas that are of most concern to men, thus enhancing patient experience and satisfaction.

The present study was designed to investigate orthorexia nervosa, or the phenomenon of being preoccupied with consuming healthy food. Specific aims were to explore relationships between orthorexia features and attitudes towards body image, fitness and health in normal weight female and male university students with high levels of healthy food preoccupation, i.e. orthorexia nervosa. Participants were 327 female (N = 283) and male (N = 44) students aged 18 to 25 years. All participants completed the Polish adaptation of the 15-item questionnaire assessing orthorexia eating behaviours (the ORTHO-15) and the Multidimensional Body-Self Relations Questionnaire (the MBSRQ). Relationships between scores on the ORTHO-15 and MBSRQ were explored in the 213 students who had high levels of preoccupation with a healthy food intake (68.55% women and 43.18% men, respectively). There were no statistically significant differences in the levels of orthorexia behaviours between females and males. In female students with orthorexia nervosa, preoccupation with consuming healthy food was significantly correlated with the MBSRQ subscale scores for overweight preoccupation, appearance orientation, fitness orientation, health orientation, body areas satisfaction and appearance evaluation. Conversely, in male students with orthorexia nervosa there were no correlations between orthorexic behaviours and the MBSRQ subscales. In female students with orthorexia nervosa multivariable linear regression analysis found high body areas (parts) satisfaction, low fitness orientation, low overweight preoccupation and low appearance orientation were independent predictors of greater fixation on eating healthy food. In male students, we found that aspects of body image were not associated with preoccupation with healthy eating. A strong preoccupation with healthy and proper food was not associated with an unhealthy body-self relationship among Polish female student with orthorexia nervosa.

Often overlooked explanations for the varied obesity rates across ethno-cultural groups include differences in attitudes toward excess weight, with certain populations assumed to have larger ideal body sizes (IBS). Past studies found ethnic and gender difference in IBS across and within different groups. This study examined the effects of ethnicity and gender, and their interaction, in accounting for differences in IBS and attitudes toward those ideals. Multiple regression analyses were used to better understand the effects of ethnicity and gender in accounting for differences in perceived IBS according to ethnic-specific and Western ideals and attitudes in 1,124 people of Native Hawaiian, Filipino, Japanese, and White ancestry. The analyses controlled for socio-demographics, body mass index, health-related behaviors, and psychosocial variables. The results indicated that Native Hawaiians selected larger ethnic IBS, Filipinos selected smaller ethnic IBS, and Native Hawaiians selected slightly smaller Western IBS than other ethnic groups. Overall, males selected larger IBS compared to females. Interaction analyses indicated that the relationship between ethnic IBS and attitude toward that IBS varied as a function of ethnicity, such that Native Hawaiians who selected a larger ethnic IBS held less favorable attitudes toward that IBS. The discrepancy between Native Hawaiians' selection of larger ethnic IBS as ideal and their less positive attitude toward that selection warrants more investigation. However, it does suggest that Native Hawaiians, on a personal level, do not prefer larger body sizes, which contradicts their perceptions of social norms. These findings have important implications for obesity interventions among Native Hawaiians. PMID:25157324

The aim of the study was to examine the prevalence and relationships between disordered eating, menstrual irregularity, musculoskeletal injuries and psychological characteristics in 24 judo athletes (12 females and 12 males) and 31 controls (14 females and 17 males). All these parameters were assessed by a health/medical, dieting and menstrual history questionnaire, the Eating Attitudes Test (EAT-26), the Multidimensional perfectionism scale, the Rosenberg Self-esteem, the Body esteem scale, and the Profile of Mood States. Body mass index (BMI) was also computed. Twenty-five percent of female athletes would be "at risk" of EDs (EAT-26 > 20) and 0 % in the other sample groups. Bone injuries sustained over the judo athlete career were reported by 25 % of females and 33.3 % of males, while 35.7 % of the female controls reported bone injuries. The total frequency of menstrual dysfunction among judo athletes was 58.3 %, while 7.1 % of female controls reported oligoamenorrhea. Regression analyses showed that BE-Weight Satisfaction and BMI contributed to 54.6 % and 17 % of the variance, respectively, in the prediction of log-transformed Global EAT scores among female judo athletes. These data indicate that while the prevalence of clinical eating disorders is low in judo athletes, many are "at risk" for an eating disorder, which places them at an increased risk for menstrual irregularity and bone injuries. This study also highlights the relevance of body esteem to eating disorder symptoms.

This study examined American attitudes toward transsexual and gay male parenting, compared to straight parenting. After reporting levels of transphobia, participants read a vignette regarding a couple seeking child adoption. Individuals high in transphobia perceived nontraditional couples as more emotionally unstable than straight couples and were less willing to grant custody of a child to the nontraditional couples vs. the straight couples. In addition, the transsexual couple faced more prejudice and discrimination than the gay male couple. Implications of these findings are discussed.

Full Text Available Background Drug abuse is a major problem in the communities and has many harmful effects on human body. Objectives The current study aimed to compare the efficacy of matrix method on anxiety and attitude of male crack abusers referred to addiction treatment centers in Tonkabon, Iran, in 2014. Patients and Methods The current semi -experimental study included 1,000 males referred to addiction treatment centers in Tonkabon with crack abuse history in 2014. Based on Morgan sample volume formula, 278 males with anxiety and higher attitude to drug abuse were randomly selected from 1,000 males referred to addiction treatment centers in Tonkabon. Then, 30 subjects were reselected out of them and equally assigned into two groups of experimental and control, 15 subjects in each group. The experimental group received 24 sessions of 30 - 60 minutes matrix treatment method in group, but the control group received no training. At the end of training period the post-test was carried out. The research findings confirmed the efficacy of matrix method on anxiety and attitude to crack abuse among those referring to the addition treatment center. Results The single covariance analysis of ANCOVA indicated that the value of Eta about 72% of variance of anxiety variable and about 76% of variance of drug abuse variable are taken in to account for variable of group. The intervention was effective in reducing anxiety and attitude to crack in males. Evaluating the adjusted mean showed the effectiveness of matrix method on anxiety and attitude to crack abuse in males. Conclusions The research result showed that matrix method affected the reduction of methamphetamine and attitude to crack abuse in males referred to the addition treatment center.

This study was carried out among undergraduate students in Universiti Malaysia Sarawak with the objective of examining gender differences in body mass index (BMI), body weight perception, eating attitudes and weightloss strategies. Subjects consisted of 600 undergraduates (300 males and 300 females) recruited from the various faculties between September 2008 until mid-November 2008. The Original Figure Rating Scale: Body Weight Perception, Body Shape Questionnaire (BSQ) and Eating Attitudes Test-26 (EAT-26) were used as assessment tools. Overall, 52.8% of students had normal BMI, with approximately an equal number of both sexes. More males than females were overweight (33.7%), while more females were underweight (25.3%). Males were more likely to perceive themselves as overweight, and fail to see themselves as underweight. More than half of the females preferred their ideal figure to be underweight, whereas about 30% males chose an overweight figure as their ideal model. Females were generally more concerned about body weight, body shape and eating than males. They diet more frequently, had self-induced vomiting, and used laxatives and exercise as their weight-loss strategies. Issues pertaining to body weight perception, eating attitudes and weight-loss strategies exist with differences among male and female undergraduates. Thus, in order to correct misperceptions among young adults, a more tailored intervention programme and more in-depth studies into the various factors involved are required.

Babusa, B; Túry, F

2012-03-01

Muscle dysmorphia (MD) has been described as a male body image disorder, characterized by a pathological preoccupation with muscle size. The aim of the study was to examine the MD features, eating disorder characteristics and body attitudes in non-competitive male bodybuilders in a Hungarian sample. Sixty male bodybuilders and 60 undergraduate university students completed the self-report questionnaires of the Muscle Appearance Satisfaction Scale, the Body Attitude Test and the Eating Disorders Inventory. MD was associated with current bodybuilding activity, higher ideal body weight and eating disorder characteristics. Moreover, current selfreported steroid users displayed higher tendency for MD symptoms than self-reported steroid non-users. Results emphasize the relationship between MD symptoms, eating disorder characteristics and steroid use. MD and body image related concerns among men could be a wide-spread phenomena also in the Central-Eastern European region.

Female perception of male body odor.

Olfaction is one of the most crucial forms of communication among nonhuman animals. Historically, olfaction has been perceived as being of limited importance for humans, but recent research has documented that not only do humans have sensitive olfactory abilities, but also odors have the potential to influence our physiology and behavior. This chapter reviews research on olfactory communication among humans, focusing on the effects of male bodily odors on female physiology and behavior. The process of body odor production and the detection of olfactory signals are reviewed, focusing on potential sex differences in these abilities. The effects of male body odors on female physiological and behavioral effects of body odors are considered. Finally, with specific regard to female mate choice, evidence regarding the influence of the major histocompatibility complex and fluctuating asymmetry on male olfactory cues is reviewed.

To examine the effects of women's subjective definitions of wife abuse and of their general attitudes to acceptance of male dominance on the occurrence of domestic violence. A case-control survey was conducted in the public health center of Babol University of Medical Sciences from November 2002 to October 2003. The Abuse Assessment Screen Form was used to identify partner violence, and the Abuse Definition Form and Abuse Attitude Form were applied to measure how the women defined wife abuse and their attitudes to male dominance. Women with positive attitudes to male dominance had experienced more physical and emotional abuse than those with negative attitudes toward male dominance (p family income were important risk factors for domestic violence, the strongest predictor of physical abuse was a positive attitude to male dominance. A positive attitude of women to male dominance increases the acceptance and frequency of partner violence. This finding shows the need to raise the educational levels of women and raise their awareness of their rights. This could convert an attitude of male dominance to equality of men and women.

Full Text Available This study aims to examine the associations between BMI, disordered eating attitude, body dissatisfaction in female adolescents, and descriptive attributes assigned to silhouettes of varying sizes in male and female adolescents, aged 11 to 15, in rural South Africa. Height and weight were measured to determine BMI. Age and sex-specific cut-offs for underweight and overweight/obesity were determined using the International Obesity Task Force cut-offs. Body image satisfaction using Feel-Ideal Discrepancy (FID scores, Eating Attitudes Test-26 (EAT-26, and perceptual female silhouettes were collected through self-administered questionnaires in 385 adolescents from the Agincourt Health and Socio-Demographic Surveillance System (HSDSS. Participants self-reported their Tanner pubertal stage and were classified as early pubertal ( 2. Mid to post pubertal boys and girls were significantly heavier, taller, and had higher BMI values than their early pubertal counterparts (all p<0.001. The prevalence of overweight and obesity was higher in the girls than the boys in both pubertal stages. The majority (83.5% of the girls demonstrated body dissatisfaction (a desire to be thinner or fatter. The girls who wanted to be fatter had a significantly higher BMI than the girls who wanted to be thinner (p<0.001. There were no differences in EAT-26 scores between pubertal groups, within the same sex, and between boys and girls within the two pubertal groups. The majority of the boys and the girls in both pubertal groups perceived the underweight silhouettes to be "unhappy" and "weak" and the majority of girls in both pubertal groups perceived the normal silhouettes to be the "best". These findings suggest a need for policy intervention that will address a healthy body size among South African adolescents.

The body teaching male: its variations and (in conformities

Full Text Available In this text we attempt to map from a dialogue with authors such as Deleuze, Guattari and Nietzsche the process of change-shift-multiplication of the male body teaching, aesthetic sensibilities and bodily assemblages that inspire pedagogical meetings. The body-teaching-male and its variations (in conformities will be taken like a registration plan and vehicle of emotional and vibratory forces which pass by and turn him on territorialisation, deterritorialization and reterritorialization movement. So, we question the pedagogical meeting place as a possible device mechanic, pointing to the idea that the assemblages produced from this place operate in the creation of body experiences that move the male body from the places consecrated by the standard approach to the male-body-marginal, replete with becoming and organized: body without organs.

Muscle dysmorphia or vigorexia is a disorder in which a person becomes obsessed with the idea that he or she is not muscular enough. To assess physical exercise, eating behaviors and the presence of muscle dysmorphia among weightlifters and medical students. Cross sectional evaluation of 88 male weightlifters aged 27 ± 7 years and 84 male medical students aged 22 ± 1 year was made. Eating behaviors were evaluated using the Eating Attitudes Test (EAT-40) and the Eating Disorders Inventory (EDI). The perception of body image was assessed using the Graduate Hannover Scale (GHS). Prevalence of muscle dysmorphia among weightlifters was 13.6%. Both groups did not differ in body dissatisfaction. Interest in appearance among weightlifters was significantly higher than in students and ranged significantly higher in EAT-40 and EDI (p < 0.001). Other sports were practiced with the same frequency by weightlifters and students. Weightlifters expended more time than students exercising to improve their appearance (p < 0.005). Forty two percent of weightlifters with muscle dysmorphia displayed abuse of anabolics and 67% used other substances to improve their performance (p < 0.005). The presence of muscle dysmorphia among weightlifters was confirmed. They were dissatisfied with their body image and more concerned with their physical appearance than those without muscle dysmorphia and/or students. Their anabolic abuse rate was high. Our findings were similar to those reported in the international literature.

Motives underlying sport and exercise involvement have recently been hypothesized as potential factors influencing the positive association between sports/exercises involvement and disturbed eating attitudes and behaviours (DEAB) among adolescents. Nevertheless, very few studies have examined this hypothesis or the moderating role of gender, context of practice, performance levels and sport type on these relationships. In this study, these questions were addressed among 168 male and 167 female French adolescents involved in various types, contexts and performance levels of sport and exercise. Participants were asked to indicate their main motives for involvement in sport practice and to self-report DEAB (generic DEAB, vomiting-purging behaviours, and eating-related control) on a French adaptation of the Eating Attitudes Test-26. The results shared positive associations between body-related sport and exercise motives and most of the DEAB subscales. Furthermore, they show that the relationship between body-related sport and exercise motives and Vomiting-Purging Behaviours differs according to involvement in individual and competitive sports and exercises.

We examined the potential moderating effects of appearance investment, body image disturbance, and situational body image dysphoria on the drive for muscularity attitude-behaviour relationship. Participants (339 British college men, M(AGE)=20.00 years, SD=2.59) completed drive for muscularity attitude and behaviour, appearance investment, body image disturbance, and situational body image dysphoria measures. Results indicated higher levels of appearance investment, body image disturbance, and situational body image dysphoria were associated with increases in the drive for muscularity attitude's relationship with physique-enhancing behavioural engagement. Results help extend recent research that has moved beyond identifying correlates to examining ways that groups of variables interact to predict drive for muscularity behavioural engagement and may contribute to theory development.

Authoritarianism has resurfaced as a research topic in political psychology, as it appears relevant to explain current political trends. Authoritarian attitudes have been consistently linked to feelings of disgust, an emotion that is thought to have evolved to protect the organism from contamination. We hypothesized that body odour disgust sensitivity (BODS) might be associated with authoritarianism, as chemo-signalling is a primitive system for regulating interpersonal contact and disease avoidance, which are key features also in authoritarianism. We used well-validated scales for measuring BODS, authoritarianism and related constructs. Across two studies, we found that BODS is positively related to authoritarianism. In a third study, we showed a positive association between BODS scores and support for Donald Trump, who, at the time of data collection, was a presidential candidate with an agenda described as resonating with authoritarian attitudes. Authoritarianism fully explained the positive association between BODS and support for Donald Trump. Our findings highlight body odour disgust as a new and promising domain in political psychology research. Authoritarianism and BODS might be part of the same disease avoidance framework, and our results contribute to the growing evidence that contemporary social attitudes might be rooted in basic sensory functions.

Due to the importance of the distorted body experience in eating disorder diagnosis and treatment, we wanted to explore body attitudes of patients with eating disorders before and after 5 months of intensive specialized outpatient day treatment. We assessed 193 patients diagnosed with Anorexia Nervosa (AN), Bulimia Nervosa (BN) and Eating Disorder Not Otherwise Specified (EDNOS) using the Body Attitude Test (BAT), Body Mass Index (BMI), Eating Disorder Evaluation Scale (EDES) and Symptom Checklist 90 (SCL-90). Eating disorder subtypes differed in BMI, total body attitudes and negative appreciation of body size at intake, but not at termination of treatment. Following treatment, all patient groups reported large improvements in eating disorder pathology and all but the AN-Restrictive (AN-R) group, reported large improvements in overall psychological functioning. The AN patients demonstrated significant improvement in BMI, however the Anorexia Nervosa purging (AN-P) and Anorexia Nervosa restrictive (AN-R) subtypes differed in their changes in body attitudes. AN-R patients indicated no significant improvement in body attitudes. AN-P patients improved in total body attitudes, except one subscale. Patients with Bulimia Nervosa non-purging (BN-NP) subtype, Bulimia Nervosa purging (BN-P) subtype and EDNOS demonstrated similar improvements in total body attitudes (BAT). Body attitudes provide important insights into differences between eating disorder diagnostic categories and their treatment responsiveness.

The current study examined body satisfaction and the value of body size among adolescents in Australia, Fiji, Malaysia, Tonga, Tongans in New Zealand, China, Chile and Greece. In total, 2489 adolescent females and 2152 males participated in the study. The results demonstrated that males were more satisfied with their body than females. Males generally had a lower BMI than females, except for males in China and Malaysia. Attitudes towards large bodies for males and females varied by cultural group. These results demonstrate the strong cultural similarities in body satisfaction, but the differences that occur in relation to a large body.

Motivational processes associated with unhealthy body change attitudes and behaviours.

Science.gov (United States)

Mussap, Alexander J

2007-08-01

The relationship between approach-avoidance motivational processes and unhealthy body change attitudes and behaviours was investigated. Self-reported sensitivity to rewards (SR) and sensitivity to punishments (SP) were measured for a convenience sample of 130 women, aged 18 to 40 years, along with measures of disordered eating symptomatology and exercise dependence. Together, SR and SP significantly predicted variance in drive for thinness (21%), bulimia (17%), and obligatory exercise (7%). These relationships were partly mediated by internalization of the thin ideal, body comparison, and subjective importance of achieving one's 'ideal' body and of avoiding one's 'worst possible' body. Interestingly, body dissatisfaction partly mediated the relationships involving SP but not SR. The results suggest that an underlying sensitivity to punishments, but not rewards, can manifest as a 'fear of fatness'. Both of these motivational traits can increase the salience of self evaluations, and thus indirectly contribute to unhealthy body change attitudes and behaviours.

Full Text Available Background: Adolescent smoking relates to numerous risk factors, of which beliefs and attitudes toward smoking may play a role. The study aimed to investigate the association between beliefs and attitudes and the risk of adolescent smoking. Materials and Methods: In a school-based cross-sectional study, 3,400 students were recruited from 34 intermediate and secondary schools in Madinah City, Al Madinah Region, Saudi Arabia. Data about sociodemographics, smoking-related factors, and beliefs and attitudes toward smoking were collected using a valid and reliable self-administered questionnaire. Prevalence of smoking was estimated and the studied beliefs and attitudes were compared by smoking status and sex using appropriate statistical analyses including multivariate logistic regression. Results: Of the 3,322 respondents, 33.02% (38.9% males and 26.4% females were current smokers. Beliefs and attitudes toward smoking significantly differed between smokers and nonsmokers in the studied male and female students. The adjusted risk of smoking was significantly increased among female adolescents who believed that male smokers were more attractive [odds ratio (OR = 2.2; 95% confidence interval (CI = 1.6-2.9] and among male smokers who believed that female smokers are more attractive (OR = 1.7; 95% CI = 1.2-2.2. The risk was also increased among all adolescents who believed that smoking lent comfort in social gatherings. Belief that smoking is harmful, however, was negatively associated with the risk of smoking, particularly among females (OR = 0.55; 95% CI = 0.35-0.91. Conclusions: The study revealed a considerable high prevalence of smoking among male and female adolescents. Addressing the beliefs and knowledge about smoking during childhood is crucial in any antismoking program.

Changes in eating attitudes, body esteem and weight control behaviours during adolescence in a South African cohort.

Directory of Open Access Journals (Sweden)

Tabither M Gitau

Full Text Available Failure to consume an adequate diet or over consumption during adolescence can disrupt normal growth and development, resulting in undesirable weight change. This leads to an increase in unhealthy weight control practices related to eating and exercise among both adolescent girls and boys to meet the societal 'ideal' body shape. This study therefore aims to examine the longitudinal changes in eating attitudes, body-esteem and weight control behaviours among adolescents between 13 and 17 years; and, to describe perceptions around body shape at age 17 years. A total of 1435 urban South African black and mixed ancestry boys and girls, who had data at both age 13 and 17 years from the Birth to Twenty cohort were included. Data were collected through self-administered questionnaires on eating attitudes (EAT-26, body esteem and weight control behaviours for either weight loss or muscle gain attempts. Height and weight were measured at both time points and BMI was calculated. Black females had a higher BMI (p<0.001 and an increased risk of developing eating disorders as well as significant increase in the prevalence of weight loss practices between the ages 13 and 17 years. At age 17 years both Mixed ancestry adolescents had lower body-esteem compared to black adolescents. The prevalence of possible eating disorders was 11% and 13.1% in early and late adolescents respectively. Males and females shared similar opinions on normal silhouettes being the 'best', 'getting respect' and being the 'happiest', while the obese silhouette was associated with the 'worst' and the 'unhappiest', and the underweight silhouette with the "weakest". Black females had a higher BMI and an increased risk of developing eating disorders. Adolescent females engaged more in weight loss practices whereas, males in muscle gain practices indicating that Western norms of thinness as the ideal are becoming more common in South Africa.

The aim of this study was to highlight the prevalence of disordered eating attitudes among male adolescents in the United Arab Emirates (UAE). A multistage stratified sampling method was used to select 731 male students aged 15-18 years from five Emirates of the UAE. The Eating Attitudes Test (EAT-26) was used to determine the prevalence of disordered eating attitudes in students. The findings revealed that the proportion of disordered eating attitudes in the UAE was relatively high compared with many developing and developed countries and ranged from 33.1% to 49.1%. Moreover, students living in the Emirates of Dubai and Al-Fujairah have double the risk of having disordered eating attitudes compared with students living in the other Emirates. The results suggest the need for screening adolescents for eating disorders, as well as for increased awareness and understanding of eating disorders and their associated risk factors in all male adolescents in the UAE. © 2014 Wiley Periodicals, Inc.

Authoritarianism has resurfaced as a research topic in political psychology, as it appears relevant to explain current political trends. Authoritarian attitudes have been consistently linked to feelings of disgust, an emotion that is thought to have evolved to protect the organism from contamination. We hypothesized that body odour disgust sensitivity (BODS) might be associated with authoritarianism, as chemo-signalling is a primitive system for regulating interpersonal contact and disease avoidance, which are key features also in authoritarianism. We used well-validated scales for measuring BODS, authoritarianism and related constructs. Across two studies, we found that BODS is positively related to authoritarianism. In a third study, we showed a positive association between BODS scores and support for Donald Trump, who, at the time of data collection, was a presidential candidate with an agenda described as resonating with authoritarian attitudes. Authoritarianism fully explained the positive association between BODS and support for Donald Trump. Our findings highlight body odour disgust as a new and promising domain in political psychology research. Authoritarianism and BODS might be part of the same disease avoidance framework, and our results contribute to the growing evidence that contemporary social attitudes might be rooted in basic sensory functions.

Full Text Available Este trabajo analiza la cambiante representación del cuerpo masculino en las obras del alemán Rainer Werner Fassbinder y el español Pedro Almodóvar. Tanto Alemania como España han tenido experiencia con regímenes altamente conservadores y fascistas que obligaron a sus ciudadanos a seguir determinados tipos de conducta en los espacios públicos y privados. Una vez que estos regímenes finalizaron, los ideales para el cuerpo masculino fueron removidos y actitudes más liberales hacia el cuerpo, sexualidad y la representación de ello fueron permitidas. Este artículo trabaja sobre cómo las películas de Fassbinder y Almodóvar representaron exitosamente el rol cambiante del cuerpo masculino.__________________ABSTRACT:This paper investigates the changing representation of the male body in the films of Germany’s Rainer Werner Fassbinder and Spain’s Pedro Almodóvar. Germany and Spain each experienced highly conservative (fascist regimes that outlined proper behavior for all citizens in both the public and private realms. Once these conservative regimes ended, ideals for the male body had been removed and more liberal attitudes towards the body, sexuality, and representation were allowed. This paper investigates how the films of Fassbinder and Almodóvar successfully portray the changing role of the male body in their films.

Impacts of exposure to images of ideal bodies on male body dissatisfaction: a review.

Science.gov (United States)

Blond, Anna

2008-09-01

Research suggests that young men's body dissatisfaction increases when they see images of attractive muscular men. This article provides the first extensive review of experimental studies exposing men to advertisements or commercials featuring idealized male bodies. Impacts on body dissatisfaction were evaluated by calculating and analyzing effect sizes from 15 studies. The effect sizes indicate that exposure to images of idealized male bodies has a small but statistically significant negative impact on men's body dissatisfaction. Three studies suggest that young men who are dissatisfied with their bodies are at increased risk for negative self-evaluations when exposed to idealized images. Two studies suggest that men who are satisfied with their bodies may be protected against negative impacts from seeing such images.

False consensus effect for attitudes related to body shape in normal weight women concerned with body shape.

Muller, S L; Williamson, D A; Martin, C K

2002-06-01

This study investigated the presence of the False Consensus Effect (FCE) with body and shape-related attitudes in 30 normal weight women who scored high or low on a measure of concern with body shape. The participants were asked to rate depressive, positive, neutral, and body shape self-statements for relevance to self and to others. They also estimated the percentage of individuals that would agree with each attitudinal statement. Women with high body shape concerns rated themselves and others as significantly more likely to agree with the statements expressing such concerns than those with low concerns. They also believed that a significantly higher percentage of others would favor those attitudes. This pattern of findings is supportive of the presence of a FCE in normal weight women preoccupied with body shape and size.

Mechanistic and "natural" body metaphors and their effects on attitudes to hormonal contraception.

2012-01-01

A small, self-selected convenience sample of male and female contraceptive users in the United Kingdom (n = 34) were interviewed between 2006 and 2008 concerning their feelings about the body and their contraceptive attitudes and experiences. The interviewees were a sub-sample of respondents (n = 188) who completed a paper-based questionnaire on similar topics, who were recruited through a poster placed in a family planning clinic, web-based advertisements on workplace and university websites, and through direct approaches to social groups. The bodily metaphors used when discussing contraception were analyzed using an interpretative phenomenological analytical approach facilitated by Atlas.ti software. The dominant bodily metaphor was mechanistic (i.e.,"body as machine"). A subordinate but influential bodily metaphor was the "natural" body, which had connotations of connection to nature and a quasi-sacred bodily order. Interviewees drew upon this "natural" metaphorical image in the context of discussing their anxieties about hormonal contraception. Drawing upon a "natural," non-mechanistic body image in the context of contraceptive decision-making contributed to reluctance to use a hormonal form of contraception. This research suggests that clinicians could improve communication and advice about contraception by recognizing that some users may draw upon non-mechanistic body imagery.

Teasing, acculturation, and cultural conflict: psychosocial correlates of body image and eating attitudes among South Asian women.

Reddy, Sheethal D; Crowther, Janis H

2007-01-01

The current study examined sociocultural correlates of body dissatisfaction and maladaptive eating attitudes among 74 South Asian American women. Participants completed measures assessing three forms of teasing--general appearance, weight/shape, and ethnic--as well as thin-ideal internalization, acculturation, cultural conflict, body dissatisfaction, and maladaptive eating attitudes. Results indicated that all three types of teasing and cultural conflict were significantly related to body dissatisfaction and maladaptive eating attitudes. Cultural conflict was found to mediate the relationship between ethnic teasing and body dissatisfaction. Neither thin-ideal internalization nor acculturation was significantly associated with either body dissatisfaction or maladaptive eating attitudes. However, body dissatisfaction was found to mediate the relationship between weight/shape teasing and maladaptive eating attitudes. Implications of these findings and possible future directions for research on South Asian American women are discussed. (c) 2007 APA, all rights reserved.

A Numerical Approach to Determine Attitude Dynamics of Floating Bodies with Irregular Configurations

2014-07-01

Full Text Available This study acquires the attitude dynamics of floating bodies with irregular configurations using an effective computational model, which has been validated theoretically and verified by experiments. By comparison a correlation formula was described to predict inclinations for the floating slender body imitating an excise torpedo. Thereafter a computational model was developed to account for bodies with attitudes in more general situations. For demonstration, a submersible was simulated to reveal that the inclinations vary abruptly around certain longitudinal locations of center of gravity. The property variations during water ingress assumption were presented. Similar to the virtue tank, an innovative concept of building the numerical data base for a specific floating body has been proposed, by which the position of its center of gravity can be obtained by interpolation from attitude data in tables as determined by the present computational model.

Male Role Endorsement Explains Negative Attitudes Toward Lesbians and Gay Men Among Students in Mexico More Than in Germany.

2015-01-01

Anti-gay attitudes vary across cultures because the larger social context plays a role in attitude formation. Psychological correlates of these attitudes have been investigated in the United States and Europe. Endorsement of traditional gender roles has emerged from that research as a central correlate, next to religiosity and personal contact with lesbians/gay men. In a cross-sectional study, we tested whether these correlates are relevant in Mexico, characterized as an androcentric culture in which both gender-role traditionalism and religiosity are high, using a college-age student sample (N = 63). Because we relied on self-reports, the motivation to appear nonprejudiced was also assessed. We found typical gender differences in attitudes toward gay men. In bivariate tests, anti-gay attitudes were related to male role endorsement, contact with lesbians/gay men, and religiosity. In a multivariate analysis, variance in attitudes was explained by male role endorsement; personal contact or religiosity did not explain additional variance. In a German comparison sample (N = 112), male role endorsement played a smaller role. Variance in anti-gay attitudes in the German sample was also related to personal contact, religiosity, and the motivation to appear nonprejudiced. We discuss the centrality of (male) gender-role endorsement in cultures with high gender-role traditionalism.

Male sexual dysfunction is a prevalent and distressing condition, which may be exacerbated by the sufferer's perceptions of masculinity and normative sexual behavior. This study sought to investigate the effect of social context on males' beliefs regarding sexual behavior. The research examined the effect of male role modeling and masculine cues on males' dysfunctional sexual beliefs, sexual attitudes, and self-perceptions of sexual functioning. A sample of 140 male participants, with a mean age of 29 years, was exposed to pictorial and verbal cues that presented different versions of male behavior across three conditions. Results indicated that males exposed to models and cues of traditional masculinity showed significantly increased levels of dysfunctional sexual beliefs and traditional sexual attitudes relative to males exposed to models of modern masculinity. Results also indicated that males exposed to traditional masculine stimuli reported lower levels of sexual inhibition due to fear of performance failure than males exposed to models of modern masculinity. The potential role of social context is discussed in the development and maintenance of male sexual dysfunction and its implications for treatment.

The study investigated the relation between body image and eating attitudes among adolescent girls in Hong Kong. A sample of 358 senior secondary school girls completed the measures assessing body-part satisfaction and behaviors associated with eating. Analysis indicated that even though only 4.8% of the girls were overweight, 85.16% desired to weigh less. These Chinese teenage girls were concerned about their weight, and the desire for slimness was widespread. Correlations indicated that higher Body Mass Index was associated with lower satisfaction with weight. Lower scores on weight satisfaction were associated with higher scores on attitudes of dieting and food preoccupation.

Full Text Available Objective: Sociocultural emphasis and increased interest in physical attractiveness and current attitudes body structure have increased body image dissatisfaction among women. The prevalence of body image dissatisfaction is linked with various psychological disorders and disturbances such as low self-esteem, depression and other disorders. The present study investigated the short program aerobic exercise effects on body image among women. Materials & Methods: In this interventional and quasi experimental study, 82 females among 150 women (18-45 years old referred to Enghelab and Gol sports clubs in Tehran were selected by convenient and simple sampling based on inclusive and exclusive criteria and randomly divided into two intervention and control groups. They did not participate in any exercise in last 3 months and also they did not have any physical disease and meet criteria for deficit of body image attitudes. Data collection was done by using demographic and Multidimensional Body Self-Relation Questionnaire. The intervention group participated in aerobic exercise program. These sessions lasted 3 hours per week for 4 weeks. Data were analyzed by Chi–Square, Paired T and Independent T tests. Results: There were significant differences between two groups after intervention in sub items of body image including: self-appearance evaluation (P<0.001, self-appearance orientation (P<0.001, health orientation (P=0.003, illness orientation (P=0.002, but their fitness evaluation (P=0.141, self-fitness orientation (P=0.888, health evaluation (P=0.072, self-body satisfaction (P=0.082, overweight preoccupations (P=0.167 and self-assesed weight (P=0.156 did not change clearly. Conclusion: Short periods of aerobic exercise can effectively promote body image attitudes among women, and exercise can be used as a method of treatment in occupational therapy of the disorder.

Low level of polyandry constrains phenotypic plasticity of male body size in mites.

Directory of Open Access Journals (Sweden)

Peter Schausberger

Full Text Available Polyandry, i.e. females mating with multiple males, is more common than previously anticipated and potentially provides both direct and indirect fitness benefits to females. The level of polyandry (defined by the lifetime number of male mates of a female is an important determinant of the occurrence and intensity of sexual selection acting on male phenotypes. While the forces of sexual selection acting on phenotypic male traits such as body size are relatively well understood, sexual selection acting on phenotypic plasticity of these traits is unexplored. We tackled this issue by scrutinizing the link between polyandry and phenotypic plasticity of male body size in two sympatric plant-inhabiting predatory mite species, Phytoseiulus persimilis and Neoseiulus californicus. These two species are similar in life history, ecological niche requirements, mating behavior, polygyny and female body size plasticity but strikingly differ in the level of both polyandry and phenotypic plasticity of male body size (both lower in P. persimilis. We hypothesized that deviations from standard body size, i.e. the size achieved under favorable conditions, incur higher costs for males in the less polyandrous P. persimilis. To test our hypotheses, we conducted two experiments on (i the effects of male body size on spermatophore transfer in singly mating females and (ii the effects of mate sequence (switching the order of standard-sized and small males on mating behavior and paternity success in doubly mating females. In P. persimilis but not N. californicus, small males transferred fewer but larger spermatophores to the females; in both species, females re-mated more likely with standard-sized following small than small following standard-sized males; in P. persimilis, first standard-sized males sired a higher proportion of offspring produced after re-mating by the female than first small males, whereas in N. californicus the paternity success of small and standard

Simple Summary We surveyed university students in 11 Eurasian countries for their attitudes to animals, using an internet-based questionnaire to which 1,902 female and 1,530 male student responded from 102 universities. Across countries female students had greater concern for animal welfare and rights than males, but especially so in more gender empowered countries. One contributing factor appeared to be the greater association of females than males with pets, and a possible outcome was greater female avoidance of meat consumption, especially red meat. Abstract Previous research has demonstrated that in households where the male partner is more dominant, there is convergence in male and female attitudes towards animals, whereas if the female partner is empowered they exhibit greater empathy towards animals than the male partner. We tested this theory of ‘female empowered empathy’ internationally in a survey of female and male students' attitudes towards use of animals, conducted in 11 Eurasian countries: China, Czech Republic, Great Britain, Iran, Ireland, South Korea, Macedonia, Norway, Serbia, Spain and Sweden. Gender empowerment was estimated for each country using the Gender Empowerment Measure designed by the United Nations. The survey was administered via the internet in universities within countries, and 1,902 female and 1,530 male student responses from 102 universities were received. Respondents rated the acceptability of 43 major concerns about human use of animals, and the importance of 13 world social issues, including animal protection, environmental protection and sustainable development. Females had greater concern for animal welfare and rights than males. There was a positive correlation between the Gender Empowerment Measure and the ratio of female to male concern for animal welfare and rights, but not for other world issues. Thus in countries where females were more empowered, principally Sweden, Norway and Great Britain, females had much

It is unknown whether body size and body shape parameters can be predictors for estimating whole body fat-free mass (FFM) in male athletes. This study aimed to investigate whether body size and shape variables can be predictors for FFM in male athletes. Using a whole-body dual-energy X-ray absorptiometry scanner, whole body fat mass (FM) and FFM were determined in 132 male athletes and 14 sedentary males. The sample was divided into two groups: validation (N = 98) and cross-validation (N = 48) groups. Body height (BH), body mass (BM), and waist circumference at immediately above the iliac crest (W) were measured. BM-to-W and W-to-BH ratios were calculated as indices of body shapes. Stepwise multiple regression analysis revealed that BM/W and W/BH were selected as explainable variables for predicting FFM. The equation developed in the validation group was FFM (kg) = 0.883 × BM/W (kg/m) + 43.674 × W/BH (cm/cm)– 41.480 [R2 = 0.900, SEE (%SEE) = 2.3 kg (3.8%)], which was validated in the cross-validation group. Thus, the current results demonstrate that an equation using BM/W and W/BH as independent variables is applicable for predicting FFM in male athletes. PMID:29346452

History, etymology, and fallacy: attitudes toward male masturbation in the ancient Western world.

This article examines the attitudes toward male masturbation in the ancient western world. More specifically, this work deals with ancient Egypt, Greece, and Rome. By comparing each epoch and geographic region, intolerance of autoerotic activity can be seen. Although there is a pattern of intolerance, the act of masturbation is always viewed provisionally. In addition, by examining these three periods of history not only can attitudes be scrutinized, but also it can be seen quite clearly that there was no golden age of sexuality: The attitude of accepted and encouraged unlimited and varied sexual practices does not exist in the ancient western world. As in many other cultures in various stages of history, procreative sexuality is the dominating theme. Thus, current attitudes of sex are derived from, and still survive due to the influence of, ancient western civilization.

In 2012 in China, 52.9% of men were reported to smoke while only 2.4% of women smoked. This study explored the smoking-related Knowledge, Attitudes and Practices (KAP) among young adult male smokers. A cross-sectional study was conducted in four municipal areas of Chongqing using a questionnaire administered to 536 natives young male smokers aged 18-45 years old. The total score of smoking cognition, the total score of smoking attitude and the total score of positive behavior to quit smoking was significantly different among the three groups by education. Besides, 30.97% of male smokers never seriously thought about quitting smoking. Logistic regression analysis found smoking-related knowledge, attitudes, behaviors and sociodemographic factors affect having smoking cessation idea. But no statistically significant correlation was observed between smoking cognition and positive behavior to quit smoking in a sample of higher education. No statistically significant correlation was observed between smoking cognition and positive behavior to quit smoking (Pearson correlation coefficient = 0.03012, p = 0.6811), and also no statistically significant correlation was observed between smoking cognition and positive behavior to quit smoking (Pearson correlation coefficient = 0.08869, p = 0.2364) in the sample of higher education young adult males Young adult males with higher education have a better knowledge of smoking hazards and a more positive attitude toward smoking, however, this knowledge and attitude do not necessarily translate into health behavioral outcomes such as not smoking. Overall the present findings indicate that no statistically significant correlation between the education level and quitting smoking idea exists among young adult male smokers in China. This survey gives a snapshot of the impact of education on smoking-related KAP among young adults male smokers.

We assessed U.S. physicians' attitudes and perceptions regarding potential human papillomavirus (HPV) vaccination of males. We surveyed a random sample of 2,714 pediatricians and family practitioners identified in administrative claims of a U.S. health plan as HPV vaccinators of females; 595 pediatricians and 499 family practitioners participated. Most physicians would recommend HPV vaccination to males aged 11-12 (63.9%), 13-18 (93.4%), and 19-26 (92.7%) years. Physicians agreed that males should be vaccinated to prevent them from getting genital and anal warts (52.9% strongly and 36.0% somewhat) and to protect females from cervical cancer (75.3% strongly and 20.8% somewhat). Physicians agreed that an HPV vaccine recommendation for males would increase opportunities to discuss sexual health with adolescent male patients (58.7% strongly, 35.3% somewhat). Most did not strongly agree (15.4% strongly, 45.4% somewhat) that parents of adolescent male patients would be interested in HPV vaccination for males, that a gender-neutral HPV vaccine recommendation would increase acceptance by adolescent females and their parents (19.6% strongly, 42.0% somewhat), or that a gender-neutral recommendation would improve current female vaccination rates (10.4% strongly, 26.0% somewhat). Physicians who currently vaccinate females against HPV supported the concept of vaccinating males for its benefits for both sexes. They agreed that a gender-neutral HPV vaccination recommendation would be appropriate with regard to public health and believed that it would increase opportunities for sexual health discussions, but were less sure that such a recommendation would change patient or parental attitudes toward HPV vaccination or improve current HPV vaccination efforts.

Male body image in Taiwan versus the West: Yanggang Zhiqi meets the Adonis complex.

Science.gov (United States)

Yang, Chi-Fu Jeffrey; Gray, Peter; Pope, Harrison G

2005-02-01

Body image disorders appear to be more prevalent in Western than non-Western men. Previous studies by the authors have shown that young Western men display unrealistic body ideals and that Western advertising seems to place an increasing value on the male body. The authors hypothesized that Taiwanese men would exhibit less dissatisfaction with their bodies than Western men and that Taiwanese advertising would place less value on the male body than Western media. The authors administered a computerized test of body image to 55 heterosexual men in Taiwan and compared the results to those previously obtained in an identical study in the United States and Europe. Second, they counted the number of undressed male and female models in American versus Taiwanese women's magazine advertisements. In the body image study, the Taiwanese men exhibited significantly less body dissatisfaction than their Western counterparts. In the magazine study, American magazine advertisements portrayed undressed Western men frequently, but Taiwanese magazines portrayed undressed Asian men rarely. Taiwan appears less preoccupied with male body image than Western societies. This difference may reflect 1) Western traditions emphasizing muscularity and fitness as a measure of masculinity, 2) increasing exposure of Western men to muscular male bodies in media images, and 3) greater decline in traditional male roles in the West, leading to greater emphasis on the body as a measure of masculinity. These factors may explain why body dysmorphic disorder and anabolic steroid abuse are more serious problems in the West than in Taiwan.

Body image during pregnancy: an evaluation of the suitability of the body attitudes questionnaire

Full Text Available Abstract Background Available data suggest that body dissatisfaction is common during pregnancy and may even be a precursor to post-natal depression. However, in order to accurately identify at-risk women, it is essential to first establish that body image measures function appropriately in pregnant populations. Our study examines the suitability of the Body Attitudes Questionnaire (BAQ for measuring body dissatisfaction among pregnant women by comparing the psychometric functioning of the BAQ: (1 across key phases of pregnancy, and (2 between pregnant and non-pregnant women. Methods A total of 176 pregnant women from Melbourne, Victoria filled out a questionnaire battery containing demographic questions and the Body Attitudes Questionnaire at 16, 24, and 32 weeks during pregnancy. A comparison group of 148 non-pregnant women also completed the questionnaire battery at Time 1. Evaluations of the psychometric properties of the BAQ consisted of a series of measurement invariance tests conducted within a structural equation modelling framework. Results Although the internal consistency and factorial validity of the subscales of the BAQ were established across time and also in comparisons between pregnant and non-pregnant women, measurement invariance tests showed non-invariant item intercepts across pregnancy and also in comparison with the non-pregnant subgroup. Inspection of modification indices revealed a complex, non-uniform pattern of differences in item intercepts across groups. Conclusions Collectively, our findings suggest that comparisons of body dissatisfaction between pregnant and non-pregnant women (at least based on the BAQ are likely to be conflated by differential measurement biases that serve to undermine attempts to accurately assess level of body dissatisfaction. Researchers should be cautious in assessments of body dissatisfaction among pregnant women until a suitable measure has been established for use in this population. Given

Given recent assertions suggesting that gender role endorsement may be relevant in the divergence of male body image concerns, this study examined the self-reported gender role endorsement in opposing dimensional extremes of male body image disorders, namely, muscle dysmorphia and anorexia nervosa. This study further examined the relationship between gender role endorsement and eating disordered and muscle dysmorphia disorder pathology. Participants were 21 male muscle dysmorphia patients, 24 male anorexia nervosa patients, and 30 male gym-using controls from Australia, the United Kingdom, and the United States. All participants completed multidimensional measures of masculinity and femininity, and measures of eating disorder and muscle dysmorphia symptomatology. Patients with muscle dysmorphia reported significantly elevated adherence to masculine (but not feminine) norms relative to control gym-using men and men with anorexia nervosa, whereas patients with anorexia nervosa exhibited elevated feminine (but not masculine) gender role endorsement relative to control gym-using men and men with muscle dysmorphia. Masculine and feminine gender role endorsement appear to be associated with the divergence of body image concerns towards muscularity and thinness-oriented ideals respectively.

Tales of healthy men: male reproductive bodies in biomedicine from 'Lebensborn' to sperm banks.

Kampf, Antje

2013-01-01

Using the example of 'sperm tales', borne out of the biomedical technologies that went hand in hand with the establishment of the 'science of man' (andrology), the article engages with the epistemic evolution of interrelated biomedical theories and concepts of what constitutes a 'healthy' reproductive male body. The article asks: how has the normative ideal male body been either perpetuated or interrogated through these tales of male reproduction at the interface between scientific and medical technologies? And how were changes to the normalization of male bodies central to clinical practices and cultural understandings of health and illness? With many aspects of the medical history of male reproduction in the 20th century still unexplored, this article will focus on the growing intervention of biomedicine to 'treat' male infertility by way of the classification, standardization and normalization of male corporeality, focusing in particular on the representation and construction of men and the male body, as reflected in medical science and practice from the second half of the 20th century onwards in Germany. The article analyses the rise in importance of sperm in biomedical investigation, including a consideration of the construction of infertility as the defining force behind concepts of 'healthy men', and examines the related conceptualization of male reproductive bodies at the crossroad between 'healthy' and 'normal'. It is argued that the ideal of male reproduction as being inherently healthy has lost ground. By the late 20th century, male bodies have become vulnerable, at least as represented in medical science and technology.

Full Text Available The aim of the present research is to present a 16-segmental biomechanical model of the Bulgarian male to determine the mass-inertial characteristics of the body of the Bulgarian male based on parameters available in the literature and its 3D generation within SolidWorks software. The motivation of the research is to support mainly sport, rehabilitation, wearable robots and furniture design users. The proposed CAD model of the human body of men is verified against the analytical results from our previous investigation, as well as through comparison with data available in the provided references. In this paper we model two basic human body positions: standing position and sitting with thighs elevated. The comparison performed between our model results and data reported in literature gives us confidence that this model can be reliably used to calculate the mass-inertial characteristics of male body at any postures of the body that is of interest. Therefore, our model can be used to obtain data for positions which the human body has to take in everyday live, in sport, leisure, including space exploration, for investigating criminology cases – body fall, car crash, etc. The model is suitable for performing computer simulation in robotics, medicine, sport and other areas.

A number of different psychological factors have been implicated in the multifactorial aetiology of disordered eating (DE) attitudes and behaviours; however, the possible role of emotional intelligence in DE symptomatology has not been thoroughly investigated in the past. The present study aimed to explore the possible differences in emotional intelligence, body image and anxiety levels in young females with DE attitudes and healthy controls. A total of 92 Greek female university students, 18-30 years old, were recruited. Subjects completed the following questionnaires: the Eating Attitudes Test (EAT-26), the Multidimensional Body-Self Questionnaire (MBRSQ), the State-Trait Anxiety Inventory (STAI) and the BarOn Emotional Intelligence Questionnaire (BarOn EQ-I). The EAT-26 revealed that 23% of the subjects presented DE attitudes. Women in the DE attitudes group had lower levels of Emotional Intelligence (EI) in comparison to the control group, particularly in factors such as emotional self-awareness (P emotional intelligence, such as emotional self-awareness and interpersonal relationships, which is an important finding in terms of the prevention and management of DE, and warrants further investigation.

2017-01-01

This study aimed to better understand the relationship between religiosity and anti-homosexual attitudes in Italy by examining the mediation effects of male role endorsement and homosexual stereotyping. A sample of 5,522 Italian residents (age range = 18-74) was drawn from a cross-sectional national representative survey carried out in 2011. Measures included general religiosity, male role endorsement, homosexual stereotyping, social acceptance of homosexuality, and homosexual rights endorsement. Structural equation modeling was used to test the mediational effects of male role endorsement and homosexual stereotyping on the relationship between general religiosity and attitudes toward lesbians and gay men. Results showed that both male role endorsement and homosexual stereotyping partially mediated the relationship. In a model where religiosity and both mediators positively explained anti-homosexual attitudes, male role endorsement was the strongest mediator. Endorsement of gender role beliefs and homosexual stereotyping may thus exacerbate the connection between religiosity and anti-homosexual attitudes among Italians.

This study investigated how dissatisfaction with particular aspects of the body was associated with overall body dissatisfaction among male adolescents in Western and Asian cultures. One hundred and six Malaysian Malays, 55 Malaysian Chinese, 195 Chinese from China, and 45 non-Asian Australians aged 12 to 19 years completed a questionnaire assessing dissatisfaction with their overall body and dissatisfaction with varying aspects of their body. Dissatisfaction with the face, height, and hair was positively correlated with overall body dissatisfaction among Malaysian Malays after body mass index, age and dissatisfaction with body areas typically included in measures (weight/shape, upper, middle, and lower body, and muscles) had been controlled for. Dissatisfaction with the face was positively correlated with overall body dissatisfaction among Malaysian Chinese. These findings demonstrate the differences in body focus for males from different cultures and the importance of using assessment measures that address all possible areas of body focus. © The Author(s) 2014.

Full Text Available We investigated body image in St. Kitts, a Caribbean island where tourism, international media, and relatively high levels of body fat are common. Participants were men and women recruited from St. Kitts (n = 39 and, for comparison, U.S. samples from universities (n = 618 and the Internet (n = 438. Participants were shown computer generated images varying in apparent body fat level and muscularity or breast size and they indicated their body type preferences and attitudes. Overall, there were only modest differences in body type preferences between St. Kitts and the Internet sample, with the St. Kitts participants being somewhat more likely to value heavier women. Notably, however, men and women from St. Kitts were more likely to idealize smaller breasts than participants in the U.S. samples. Attitudes regarding muscularity were generally similar across samples. This study provides one of the few investigations of body preferences in the Caribbean.

Galioto, Rachel; Crowther, Janis H

2013-09-01

This research examined the effects of appearance-based comparisons to muscular and slender idealized male bodies and the contribution of internalization and social comparison to change in body dissatisfaction. Participants were 111 male undergraduates who completed measures of body dissatisfaction, internalization, and social comparison and viewed images of either muscular or slender men in advertisements or product-only advertisements. Results indicated that exposure to both muscular and slender images was associated with an increase in body dissatisfaction, with no significant differences in the change in body dissatisfaction between the two image conditions. Internalization and trait social comparison were each associated with an increase in body dissatisfaction; however, upward social comparison was only a significant predictor of a change in body dissatisfaction for the males who viewed muscular images. These results highlight the impact of slender models on young men's body dissatisfaction and support the examination of media literacy interventions with this population.

A role for the adult fat body in Drosophila male courtship behavior.

Directory of Open Access Journals (Sweden)

Anna A Lazareva

2007-01-01

Full Text Available Mating behavior in Drosophila depends critically on the sexual identity of specific regions in the brain, but several studies have identified courtship genes that express products only outside the nervous system. Although these genes are each active in a variety of non-neuronal cell types, they are all prominently expressed in the adult fat body, suggesting an important role for this tissue in behavior. To test its role in male courtship, fat body was feminized using the highly specific Larval serum protein promoter. We report here that the specific feminization of this tissue strongly reduces the competence of males to perform courtship. This effect is limited to the fat body of sexually mature adults as the feminization of larval fat body that normally persists in young adults does not affect mating. We propose that feminization of fat body affects the synthesis of male-specific secreted circulating proteins that influence the central nervous system. In support of this idea, we demonstrate that Takeout, a protein known to influence mating, is present in the hemolymph of adult males but not females and acts as a secreted protein.

Some research suggests adorning the body with tattoos or piercing jewelry is normative. Survey data were gathered from 450 undergraduates (72% female; 80% Euro-American; 63% freshmen and sophomores). Correlations between an index of respondents' religious belief and practice and their attitudes toward individuals who had more body piercings were weak if piercings were 7 or more, including piercings of the nipples and genitals. As religiosity is a carrier of normative behavior, individuals who have body piercings may be viewed as behaving within cultural norms.

The aim of the present study was to examine the disordered eating attitudes and sociocultural body ideals internalization among university athletes (N.=98), exercisers (N.=125) and sedentary (N.=81) undergraduate female students. The mean age (SD) of the sample was 20.17 (2.00). The students completed Eating Attitude Test - 26, Body Areas Satisfaction subscale of the Multidimensional Body-Self Relations Questionnaire, Body Shame subscale from the Objectified Body Consciousness Scale, Rosenberg Self- Esteem Scale, Appearance subscale from the Motives for Physical Activity Measure--Revised, reported their physical activity and fluid manipulation-related behaviour. We observed no significant differences in disordered eating, body dissatisfaction, self-esteem and fluid manipulation-related behaviour among athletes, exercisers and sedentary female students. Body shame predicted disordered eating in all groups of women. Students high in body shame reported higher levels of disordered eating, body dissatisfaction, appearance-related exercise motives, fluid manipulation-related behaviour and lower self-esteem, regardless of their physical activity level. The results show that internalization of the sociocultural body standards provide a mechanism through which different physical activity levels are associated with negative eating and physical activity-related outcomes in college-aged women.

Canalization of body size matters for lifetime reproductive success of male predatory mites (Acari: Phytoseiidae).

Science.gov (United States)

Walzer, Andreas; Schausberger, Peter

2014-04-01

The adaptive canalization hypothesis predicts that highly fitness-relevant traits are canalized via past selection, resulting in low phenotypic plasticity and high robustness to environmental stress. Accordingly, we hypothesized that the level of phenotypic plasticity of male body size of the predatory mites Phytoseiulus persimilis (low plasticity) and Neoseiulus californicus (high plasticity) reflects the effects of body size variation on fitness, especially male lifetime reproductive success (LRS). We first generated small and standard-sized males of P. persimilis and N. californicus by rearing them to adulthood under limited and ample prey supply, respectively. Then, adult small and standard-sized males were provided with surplus virgin females throughout life to assess their mating and reproductive traits. Small male body size did not affect male longevity or the number of fertilized females but reduced male LRS of P. persimilis but not N. californicus . Proximately, the lower LRS of small than standard-sized P. persimilis males correlated with shorter mating durations, probably decreasing the amount of transferred sperm. Ultimately, we suggest that male body size is more strongly canalized in P. persimilis than N. californicus because deviation from standard body size has larger detrimental fitness effects in P. persimilis than N. californicus .

School-based athletic programs remain an important context for violence prevention efforts although a better understanding of how gender attitudes and abuse perpetration differ among athletes is needed. We analyzed baseline survey data from the "Coaching Boys into Men" study-a school-based cluster-randomized trial in 16 high schools in Northern California. We describe relationships among gender-inequitable attitudes, sport type, and recent adolescent relationship abuse perpetration among a sample of male athletes (n = 1,648). Gender-inequitable attitudes (adjusted odds ratio (AOR), 3.26; 95% confidence interval (CI), 2.56, 4.15), participation in both high school football and basketball (AOR, 2.08; 95% CI, 1.37, 3.18), and participation in football only (AOR, 1.50; 95% CI, 1.02, 2.22) emerged as independently associated with recent ARA perpetration. Findings warrant targeted violence prevention efforts among male high school athletes that incorporate discussions of gender attitudes and healthy relationships, especially among sports teams at greater risk of adolescent relationship abuse perpetration.

Little, Anthony C; Jones, Benedict C; Burriss, Robert P

2007-05-01

In human females cyclic shifts in preference have been documented for odour and physical and behavioral male traits. Women prefer the smell of dominant males, more masculine male faces and men behaving more dominantly when at peak fertility than at other times in their menstrual cycle. Here we examine variation in preferences for body sexual dimorphism. Across two studies, both between- and within-participant, we show that women prefer greater masculinity in male bodies at times when their fertility is likely highest, in the follicular phase of their cycle. Shifts were seen when rating for a short-term but not when rating for a long-term relationship. In line with studies showing similar effects for facial sexual dimorphism, we also show that women prefer greater masculinity when they think themselves attractive than when they think themselves less attractive. These results indicate that women's preferences for sexual dimorphism in male bodies follow a similar pattern as found for sexual dimorphism and dominance in other domains and such differences in preference may serve a similar function. Cyclic preferences could influence women to select partners when most likely to become pregnant that possess traits that may be most likely to maximize their offspring's quality via attraction to masculinity or serve to help acquire investment via attraction to femininity.

The Sex Determination Gene transformer Regulates Male-Female Differences in Drosophila Body Size.

Rideout, Elizabeth J; Narsaiya, Marcus S; Grewal, Savraj S

Almost all animals show sex differences in body size. For example, in Drosophila, females are larger than males. Although Drosophila is widely used as a model to study growth, the mechanisms underlying this male-female difference in size remain unclear. Here, we describe a novel role for the sex determination gene transformer (tra) in promoting female body growth. Normally, Tra is expressed only in females. We find that loss of Tra in female larvae decreases body size, while ectopic Tra expression in males increases body size. Although we find that Tra exerts autonomous effects on cell size, we also discovered that Tra expression in the fat body augments female body size in a non cell-autonomous manner. These effects of Tra do not require its only known targets doublesex and fruitless. Instead, Tra expression in the female fat body promotes growth by stimulating the secretion of insulin-like peptides from insulin producing cells in the brain. Our data suggest a model of sex-specific growth in which body size is regulated by a previously unrecognized branch of the sex determination pathway, and identify Tra as a novel link between sex and the conserved insulin signaling pathway.

Interdependent effects of male and female body size plasticity on mating behaviour of predatory mites.

Walzer, Andreas; Schausberger, Peter

2015-02-01

The adaptive canalization hypothesis predicts that traits with low phenotypic plasticity are more fitness relevant, because they have been canalized via strong past selection, than traits with high phenotypic plasticity. Based on differing male body size plasticities of the predatory mites Phytoseiulus persimilis (low plasticity) and Neoseiulus californicus (high plasticity), we accordingly hypothesized that small male body size entails higher costs in female choice and male-male competition in P. persimilis than N. californicus . Males of both species are highly polygynous but females differ in the level of polyandry (low level in P. persimilis ; medium level in N. californicus ). We videotaped the mating interactions in triplets of either P. persimilis or N. californicus , consisting of a virgin female (small or standard-sized) and a small and a standard-sized male. Mating by both small and standard-sized P. persimilis females was biased towards standard-sized males, resulting from the interplay between female preference for standard-sized males and the inferiority of small males in male-male competition. In contrast, mating by N. californicus females was equally balanced between small and standard-sized males. Small N. californicus males were more aggressive ('Napoleon complex') in male-male competition, reducing the likelihood of encounter between the standard-sized male and the female, and thus counterbalancing female preference for standard-sized males. Our results support the hypothesis that male body size is more important to fitness in the low-level polyandrous P. persimilis than in the medium-level polyandrous N. californicus and provide a key example of the implications of sexually selected body size plasticity on mating behaviour.

Male attitude about masturbation may influence early diagnosis and treatment of infertility and may be of particular burden in developing countries. We sought to explore attitude about masturbating and examine comfort/discomfort with masturbating and sexual history, pregnancy history and sperm quality in men investigating fertility potential. The study consisted of 83 male volunteers, 23-61 years, attending a fertility management unit in Kingston, Jamaica. Comfort with masturbation was assessed by a self-administered questionnaire. Participants also completed the unit's standard intake form for infertility investigations and produced a semen sample. T-tests, Mann-Whitney U-test and chi-square were used to compare differences in comfort level with outcome variables. We found 59% were comfortable masturbating although requiring external stimulation to produce a sample (48%); 6% (n = 5) failed to produce a sample after repeated attempts. A higher percentage of men uncomfortable with masturbating reported sexual problems (P masturbating comfort. Producing a sample by masturbation is standard for many assisted conception treatments. As comfort with masturbating may influence delay in infertility investigations and fertility outcome, efforts to improve men's comfort level with semen production should be considered in pre-treatment fertility counselling. © 2015 Blackwell Verlag GmbH.

The primary aim of this study was to investigate the relationship between gender role orientation and eating disorder attitudes and behaviors and body dissatisfaction in a sample of homosexuals, heterosexuals, and transsexuals. We screened 132 homosexuals, 178 heterosexuals (both male and female), and 15 MtF transsexuals by means of an ad hoc socio-demographic schedule; the Eating Disorders Inventory-2 and Symptom Checklist; the Body Uneasiness Test and the Bem Sex Role Inventory. Differences between homosexual, heterosexual, and transsexual participants emerged, but those data seem to be best explained by the constructs of femininity and masculinity than by the biological gender. The empirical evidence of a positive correlation between femininity and eating problems, and the negative correlation between masculinity and eating problems, is full of implications. Eating disorders appear to be diseases of femininity; masculinity seems to be a protective factor, independently by the biological gender.

2002-06-01

Multi-body spacecraft attitude and configuration control formulations based on the use of collaborative control theory are considered. The control formulations are based on two-player, nonzero-sum, differential game theory applied using a Nash strategy. It is desired that the control laws allow different components of the multi-body system to perform different tasks. For example, it may be desired that one body points toward a fixed star while another body in the system slews to track another satellite. Although similar to the linear quadratic regulator formulation, the collaborative control formulation contains a number of additional design parameters because the problem is formulated as two control problems coupled together. The use of the freedom of the partitioning of the total problem into two coupled control problems and the selection of the elements of the cross-coupling matrices are specific problems addressed in this paper. Examples are used to show that significant improvement in performance, as measured by realistic criteria, of collaborative control over conventional linear quadratic regulator control can be achieved by using proposed design guidelines.

The effects of cold stress on exercise performance and fatigue have been thoroughly investigated only in males, and thus the general understanding of these effects relates only to males. The aim of this study was to determine whether whole-body cooling has different effects on performance during fatiguing exercise in males and females. Thirty-two subjects (18 males and 14 females) were exposed to acute cold stress by intermittent immersion in 14°C water until their rectal temperature reached 35.5°C or for a maximum of 170 min. Thermal responses and motor performance were monitored before and after whole-body cooling. Whole-body cooling decreased rectal, muscle and mean skin temperatures in all subjects (pCold stress decreased the fatigue index (FI) of a sustained 2-min maximal voluntary contraction (MVC) only in males (pbody cooling-induced decrease in the FI of a sustained MVC in males but not in females) supports the view of sex effects on performance during fatiguing exercise after whole-body cooling.

The population of the study is consisted of Burdur province and high schools located in the selected district and the sample group consists of students studying at the 9th, 10th, 11th, 12th grade in these schools. The data have been obtained from the written sources and by using survey methods. The attitude scale of physical education and sports classes for secondary school students developed by Güllü and Güçlü (2007 has been used. Questionnaires have been applied to the sample group by being consulted with one to one by sampling method. 950 individuals in total, 522 women and 428 men, have answered to the questionnaire. The data obtained have been transferred to a computer for statistical process and as statistical procedures, frequency (% and Independent samples t- test, to determine the difference between variables, have been applied. In the detection of differences, reviews have been made by being adopting the significance level of 0.05 in compliance with the answer distributions given to each question and the averages. Results: According to the obtained data; according to the responses of the surveyed high school students studying in average, their attitudes are positive to physical education and sports lessons; it is seen that there is a significant relationship in the significance level of 0,05 in comparative statistical procedures (p <0.05 . Conclusion: As a result; we can say that students' attitudes towards physical education and sports classes participated in the survey are positive, but male students have more positive attitudes than female students.

Field and laboratory studies were conducted to examine the effects of nest availability and body size on changes in male mating tactics from sneaking to nest-holding in the dusky frillgoby Bathygobius fuscus. In the field, the body size of nest-holding males decreased from early to mid-breeding season, suggesting the possibility of a change in the tactics of sneaker males to nest-holding. Many sneaker males did not use vacant spawning nests even when size-matched nests were available, but they continued to reproduce as sneakers. Similarly, in aquarium experiments with available vacant nests, some sneaker males became nest-holders irrespective of their body size, but some did not. These results showed that nest availability is not a limiting factor for changes in tactics by sneaker males in this species. Because tactic-unchanged sneaker males were co-housed with larger nest-holding males in the tanks, the body size of nearby nest-holding males may have affected the decision to change tactics for sneaker males. Moreover, smaller individuals among tactic-changed males tended to spend more time until spawning, probably because they had relatively larger costs and smaller benefits of reproduction as nest-holding males compared to larger males. © 2012 The Authors.

To explore male students' attitudes towards menstruation. Menstruation is a biological event that is often surrounded by secrecy and social stigma that causes anxiety amongst many young girls. A key element of this is the attitudes of young males towards this reproductive health issue. However, the literature around what young males think and feel about menstruation is limited. Qualitative. A sample of 27 male students aged between 10-12 years participated in five focus groups. Data were then subject to a thematic analysis. Five themes emerged from the data analysis that reflected the boys' feelings, experiences and attitudes towards menstruation: 'A silent topic', 'An unimportant issue', 'Errant information about menstruation'. In addition, according to their experience, participants gradually came to see menstruation from the 'menstrual stereotype' viewpoint. In their social life, they made choices that resulted in gradually regulating their behaviour that affected their 'relationships with girls'. Young boys have misguided knowledge about menstruation and this helps to perpetuate the stigma surrounding this element of reproductive health. Boys also express a desire to learn more but are often restricted in this by home and school. School nurses are the best placed professionals to address this issue. Menstrual education with boys should take a greater prominence than it often does in sexual health education in schools. Such inclusion will provide boys with a balanced and accurate knowledge base and therefore help towards reducing the social stigma around menstruation that is often experienced by young girls. © 2011 Blackwell Publishing Ltd.

Body size correlates with fertilization success but not gonad size in grass goby territorial males.

Directory of Open Access Journals (Sweden)

Jose Martin Pujolar

Full Text Available In fish species with alternative male mating tactics, sperm competition typically occurs when small males that are unsuccessful in direct contests steal fertilization opportunities from large dominant males. In the grass goby Zosterisessor ophiocephalus, large territorial males defend and court females from nest sites, while small sneaker males obtain matings by sneaking into nests. Parentage assignment of 688 eggs from 8 different nests sampled in the 2003-2004 breeding season revealed a high level of sperm competition. Fertilization success of territorial males was very high but in all nests sneakers also contributed to the progeny. In territorial males, fertilization success correlated positively with male body size. Gonadal investment was explored in a sample of 126 grass gobies collected during the period 1995-1996 in the same area (61 territorial males and 65 sneakers. Correlation between body weight and testis weight was positive and significant for sneaker males, while correlation was virtually equal to zero in territorial males. That body size in territorial males is correlated with fertilization success but not gonad size suggests that males allocate much more energy into growth and relatively little into sperm production once the needed size to become territorial is attained. The increased paternity of larger territorial males might be due to a more effective defense of the nest in comparison with smaller territorial males.

The central role of males in female reproductive health issues in patriarchal societies makes them an important group in the eradication of female genital mutilation/cutting (FGM/C). To determine knowledge about and attitudes to FGM/C among male adolescents, and their preparedness to protect their future daughters from it. A cross-sectional survey among male adolescent students in Ilorin, Nigeria. Participants completed a self-administered questionnaire after consent had been obtained from them or their parents. Statistical analysis was with SPSS version 20.0 (IBM, USA). A p-value of <0.05 was taken as significant. Of 1 536 male adolescents (mean age 15.09 (standard deviation 1.84) years, range 14 - 19), 1 184 (77.1%) were aware of FGM/C, 514 (33.5%) supported female circumcision, 362 (23.6%) would circumcise their future daughters, 420 (27.3%) were of the opinion that FGM/C had benefits, mostly as a necessity for womanhood (109, 7.1%), and 627 (40.8%) perceived it as wickedness against females; 546 (35.5%) were aware of efforts to eradicate FGM/C, and 42.2% recommended education as the most important intervention to achieve this. Education and involvement in advocacy may transform male adolescents into agents for eradication of FGM/C.

Masculine body ideologies as a non-gynocentric framework for the psychological study of the male body.

Rosenmann, Amir; Kaplan, Danny

2014-09-01

Psychological research of the body disproportionately centers on body-appearance concerns. Grounded in women's experience of objectification, it neglects much of men's bodily experience. To address this we introduce Masculine Body Ideologies (MBI), a set of belief systems that prescribe how men should engage with their bodies. Three MBI ideal-types are identified and situated within broader masculinity ideologies: unattended, functional body ideology associated with traditional masculinity rooted in modern industrial society; metrosexual body ideology associated with post-industrial, consumer masculinity and reemploying signifiers of body functionality to form an objectified body esthetics; and holistic body ideology emphasizing inner-harmony, authenticity and expressivity, manifesting post-industrial trends of self-aware masculinity. As a normative framework, MBI underscores how similar body practices may be motivated by different body concerns associated with alternative body ideologies. This framework can clarify conceptual and empirical inconsistencies in studies of male body-appearance concerns and inform emerging research and mental-health considerations.

Grossbard, Joel R; Lee, Christine M; Neighbors, Clayton; Larimer, Mary E

2009-02-01

Body dissatisfaction in females, and to a lesser extent males, is associated with low self-esteem, depression, and eating disorders. This research examined gender as a moderator of the association between contingent self-esteem and body image concerns, including weight and muscularity. Participants included 359 (59.1% female) heavy drinking first-year U.S. undergraduate students who completed a survey assessing health-related risk behaviors. Hierarchical multiple regression was used to examine relations among gender, contingent self-esteem, and body image. Females reported higher levels of contingent self-esteem and greater concerns about their weight, although males reported a greater drive for muscularity. The relationship between contingent self-esteem and weight concerns was stronger among females, and for males, greater contingent self-esteem was associated with a greater drive for muscularity.

Full Text Available Background: Adverse cardiovascular events have been reported in body builders taking anabolic steroids. Adverse effects of AAS on endothelial function can initiate atherosclerosis. This study evaluates endothelial function in body builders using AAS, compared with non-steroids using athletes as controls. Methods: We recruited 30 nonsmoking male body builders taking AAS, 14 in build up phase, 8 in work out phase, and 8 in post steroid phase, and 30 nonsmoking male athletes who denied ever using steroids. Serum lipids and fasting plasma glucose were measured to exclude dyslipidemia and diabetes. Brachial artery diameter was measured by ultrasound at rest, after cuff inflation, and after sublingual glyceriltrinitrate (GTN to determine flow mediated dilation (FMD, nitro mediated dilation (NMD and ratio of FMD to NMD (index of endothelial function. Result: Use of AAS was associated with higher body mass index (BMI and low density lipoprotein–cholesterol (LDL-C. Mean ratio of flow mediated dilatation after cuff deflation to post GTN dilatation of brachial artery (index of endothelial function in body builders taking AAS was significantly lower than control group (0.96(0.05 versus 1(0.08; p=0.03. After adjusting BMI, age and weight, no significant difference was seen in index of endothelial function between two groups (p=0 .21. Conclusion: Our study indicates that taking AAS in body builders doesn’t have direct effect on endothelial function. Future study with bigger sample size and measurement of AAS metabolites is recommended. Key words: endothelium, lipids, anabolic steroids, body builders

Sociocultural influences on eating attitudes and behaviors, body image, and psychological functioning: a comparison of African-American, Asian-American, and Caucasian college women.

Eating attitudes and behaviors, body image, and psychological functioning were evaluated in 98 female college students: 36 African-Americans, 34 Asian-Americans, and 28 Caucasians. African-Americans had significantly higher body mass index than either Asian-American or Caucasians. In contrast, Caucasians reported greater levels of disordered eating and dieting behaviors and attitudes and greater body dissatisfaction than did Asian-Americans and African-Americans who differed little on these measures. The nature of variability in these eating behaviors and attitudes and body image was also examined within each of the three groups. A generally consistent pattern emerged within each racial group: low self-esteem and high public self-consciousness were associated with greater levels of problematic eating behaviors and attitudes and body dissatisfaction. A history of being teased about weight and size was associated with problematic eating behaviors and attitudes and body dissatisfaction in African-Americans and Caucasians but not in Asian-Americans. The findings suggest that there exist important racial differences on various aspects of eating, dieting, and body image in college women. Contrary to hypothesis, the degree of acculturation and assimilation within the African-American and Asian-American groups was unrelated to variability in these domains.

The purpose of this study was to evaluate body composition and body image (perception and satisfaction) in a group of young elite soccer players and to compare the data with those of a control group (age and BMI matched). Participants were 56 volunteer males whose mean age and BMI were 19.6 (SD 1.3) years and 23.3 (SD 1.1) kg/m2, respectively. Results showed that soccer players have a higher lean mass and lower fat mass than controls. Moreover, body perception (difference between current and actual image) was more accurate in controls than in soccer players, and the results suggest a tendency for soccer players to aspire to have more muscle mass and body fat. Soccer players perceived an ideal image with significantly higher body-fat percentage than their current and actual images. There were no body-dissatisfaction differences between groups, however. Although the results are necessarily limited by the small sample size, the findings should be of interest to coaches of young elite soccer teams.

Change my body, change my mind: the effects of illusory ownership of an outgroup hand on implicit attitudes toward that outgroup.

The effect of multisensory-induced changes on body-ownership and self-awareness using bodily illusions has been well established. More recently, experimental manipulation of bodily illusions have been combined with social cognition tasks to investigate whether changes in body-ownership can in turn change the way we perceive others. For example, experiencing ownership over a dark-skin rubber hand reduces implicit bias against dark-skin groups. Several studies have also shown that processing of skin color and facial features play an important role in judgements of racial typicality and racial categorization independently and in an additive manner. The present study aimed at examining whether using multisensory stimulation to induce feelings of body-ownership over a dark-skin rubber hand would lead to an increase in positive attitudes toward black faces. We here show, that the induced ownership of a body-part of a different skin color affected the participants' implicit attitudes when processing facial features, in addition to the processing of skin color shown previously. Furthermore, when the levels of pre-existing attitudes toward black people were taken into account, the effect of the rubber hand illusion on the post-stimulation implicit attitudes was only significant for those participants who had a negative initial attitude toward black people, with no significant effects found for those who had positive initial attitudes toward black people. Taken together, our findings corroborate the hypothesis that the representation of the self and its relation to others, as given to us by body-related multisensory processing, is critical in maintaining but also in changing social attitudes.

Full Text Available The study investigated the relationship between body image dissatisfaction, nutritional status, and eating attitudes in adolescents from a small town of the interior of São Paulo State. A total of 278 adolescents (106 boys and 172 girls aged between 15 and 18 years had completed measures of body image dissatisfaction through the Figure Rating Scale and eating attitudes by the Eating Attitudes Test (EAT-26 and had their weight and height measured. Girls related more dissatisfaction and abnormal eating behavior than boys and, in both genders the abnormal eating attitudes tend to increase with increasing dissatisfaction. Moreover, dissatisfaction was higher between those individuals classified as overweight and obesity. These results demonstrated that body image dissatisfaction and inappropriate eating behaviors afflict boys and girls even from small cities in developing countries, highlighting the need to undertake epidemiological studies to early recognition of populations at risk of developing eating disorders.

The aim of the present study was to examine the relationship between celebrity worship and body image within the theoretical perspective of intense para-social relationships with celebrities. Correlation and multiple regression analyses were used to examine the relationships between celebrity worship and body image. Three samples, 229 (102 males and 127 females) adolescents, 183 (88 males and 95 females) full-time university undergraduate students, and 289 (126 males and 163 females) adults were administered an amended version of the Celebrity Attitude Scale, the Attention to Body Shape Scale, and the Body Shape Questionnaire-Revised. Significant relationships were found between attitudes toward celebrities and body image only among female adolescents. Multiple regression analyses suggested that Intense-personal celebrity worship accounted for unique variance in scores in body image. Findings suggest that in female adolescents, there is an interaction between Intense-personal celebrity worship and body image between the ages of 14 and 16 years, and some tentative evidence has been found to suggest that this relationship disappears at the onset of adulthood, 17 to 20 years. Results are consistent with those authors who stress the importance of the formation of para-social relationships with media figures, and suggest that para-social relationships with celebrities perceived as having a good body shape may lead to a poor body image in female adolescents.

Full Text Available Certain patologies are accepted as characterized with relevant certain cognitive distortions. Eating Disorders and Obssessive Compulsive Disorders (OCD are related in terms of comorbidite, existence of similar distortions and intrusive thoughts. Distorted cognitions related with body shape and weight are associated with eating disorders and the distorted cognition which was conceptualised as thought shape fusion is accepted as a version of thought action fusion which is commonly seen at OCD. Because of its practical and theoretical relevance the aim of the present study is investigation of the relationship of eating attitudes of individuals with thought shape fusion cognitive distortion and gender and body mass index (BMI. Participants are 73 university students with age range 18-28 (58 male. Eating Attitudes Test (EAT and Thought Shape Fusion Scale (TSFS have been used for data collection. A positive correlation was found between TSFS and EAT (r= 0.53, p=0.01 and TSFS and BMI (r=0,34, p=0,01. According to stepwise regression analysis primary predictor of TSFS scores are EAT scores; %28 of the variance of the TSFS was explained by EAT scores and when BMI and gender variables are added the explained variance is %47. Women differed with significantly higher means in terms of EAT scores. Groups were formed according to pathology cut point of EAT scale (≥30 and the group above the cut point differed with significantly higher TSFS mean scores. Results of the present study seems parallel with the claims which associates eating disorders with distorted cognitions which are expressions of intrusive thoughts similar to OCD and associated with characteristics of eating disorders as overrating of food, body weight and shape. Findings are evaluated as having practical and theoretical significance. It is hoped that after supported with future studies the findings of the present study will be useful by adding to the existing knowledge in the field which

Medical male circumcision (MMC) is a key strategy in the South African HIV infection prevention package. Women may have a potentially powerful role in supporting such a strategy. Circumcision is not a traditional part of Zulu society, and Zulu women may have limited knowledge and ambivalent or negative attitudes towards MMC. This study employs quantitative data to expand insight into rural Zulu women's knowledge of and attitudes towards MMC, and is important as women could potentially yield a powerful positive or negative influence over the decisions of their partners and sons. A hospital-based antenatal clinic in rural KwaZulu-Natal. Participants were 590 pregnant, mostly isiZulu-speaking women. Data on their knowledge of and attitude towards MMC were collected using a questionnaire and were analysed descriptively. The majority of the women supported MMC; however, knowledge of the potential benefits was generally poor. Most would encourage their partners and sons to undergo MMC. The preferred place for the procedure was a hospital. Zulu participants supported MMC and would support their partners and children being circumcised. Knowledge around potential benefits was worryingly poor, and further research into disseminating information is essential. The findings highlight the need for an expanded campaign of health education for women, and innovative means are suggested to enhance information accessibility. Reasons for preferring that MMC be carried out in hospital need to be explored further.

Cadaveric dissection remains an important part of undergraduate medical education in anatomy. In a concerted effort to rise the number of doctors in practice in Ireland the amount of medical school placements has been increased steadily since 1995. This poses a problem as the number of cadavers has remained unchanged despite an overall increase in the population Ireland over the last twenty years. The medical profession plays a central part in raising public awareness of living and post-mortem organ donation. Previous studies have examined the attitudes of medical students to whole body donation, however to our knowledge this is the first study that evaluates the attitudes of medical professionals. We assess the opinions of junior and senior doctors at the time of their dissection experience and in their current practice. We show that their attitudes have changed as their clinical experience grows.

Presently, the internet plays a big role in daily life, especially for adolescents. In this age group, they are more concerned about their face and body shape. Despite the numerous studies on the effect traditional media has on body image, very few have focused on the effect of newer forms of media (e.g. online media). And almost none have looked at the relationship between time spent online and body image. To study the associations between time spent on the internet, body image satisfaction and eating behaviors of students grades 7 to 12 in the Thai educational system. The sample group included 620 students, who were selected using simple random sampling from 6 secondary schools in Bangkok. Data were collected using the Media and Internet use behavior questionnaires, The Body-Esteem Scale for Adolescents and Adults: Thai version (BESAA), Drive for Muscularity Scale (DMS: males only), The Rosenberg Self-Esteem Scale: Thai version, Eating Attitude Test-26: Thai version (EAT-26) and the eating behaviors at risk of obesity questionnaire. Mean (sd) age of the sample was 15.7 (1.9) years, 246 participants (39.7%) were male and 374 (60.3%) were female. Using the internet and social networks for content related to body image and eating behaviors, was negatively associated with body image satisfaction but positively associated with inappropriate eating attitudes/behaviors, binging, purging, use of laxatives/diuretics and drive for muscularity with respect to behaviors and attitudes, and was associated with eating behaviors that carried a risk for obesity. Time spent on internet, especially engaged in activities related to self-image, and eating attitudes and behaviors, were associated with a decrease in body image satisfaction and problematic eating behaviors.

This study sought to examine the effects of media images on men's attitudes toward their body appearance. A group of college men viewed advertisements showing muscular men, whereas a control group viewed neutral advertisements. Immediately thereafter, participants performed a computerized test of body image perception while unaware of the hypotheses being tested in the study. The students exposed to the muscular images showed a significantly greater discrepancy between their own perceived muscularity and the level of muscularity that they ideally wanted to have. These findings suggest that media images, even in a brief presentation, can affect men's views of their bodies. Copyright 2002 by Wiley Periodicals, Inc.

One efficacious strategy to help prevent HIV is oral pre-exposure prophylaxis (PrEP), a daily regimen of antiretroviral treatment taken by HIV-negative individuals. Two of the recommendations of Centers for Disease Control and Prevention (CDC) guidelines for PrEP pertain to being in a relationship (i.e., male couples). Despite the recognition of how primary partners in male couples' relationships shape HIV risk and CDC's PrEP guidelines, there is a paucity of data that examine HIV-negative male couples' attitudes toward PrEP use and using PrEP with a sexual agreement. A sexual agreement is an explicit agreement made between two individuals about what sex and other related behaviors may occur within and outside of their relationship. In this qualitative study, we examine HIV-negative male couples' attitudes toward PrEP use and whether they thought PrEP could be integrated into a sexual agreement. Data for this study are drawn from couple-level interviews conducted in 2014 with 29 HIV-negative male couples who had a sexual agreement and were from Atlanta or Detroit. Both passive (e.g., flyers) and active (e.g., targeted Facebook advertisements) recruitment methods were used; the sample was stratified by agreement type. Thematic analysis was applied to identify the following themes regarding HIV-negative male couples' attitudes toward PrEP use: (1) PrEP and condom use; (2) concerns about PrEP (e.g., effectiveness, side effects, and promoting sexually risky behavior); and (3) accessibility of PrEP. Some thought PrEP could be a part of couples' agreement because it could help reduce sexual anxiety and sexual risk, and would help keep the couple safe. Others described PrEP use with an agreement as something for "others". Some were also concerned that incorporating PrEP could usurp the need for a sexual agreement in a couples' relationship. These themes highlight the need to improve informational messaging and promotion efforts about PrEP among HIV-negative male couples

Testicular cancer incidence rates are increasing worldwide making it the most common malignancy in males aged 15 to 45 years. Without a known way to prevent the disease health professionals must promote awareness and early detection. A literature review identified a scarcity of information regarding awareness and knowledge of, and attitudes toward, testicular cancer and testicular self-examination among men in Northern Ireland. This study aimed to establish baseline data for Northern Ireland using a convenience sample of 150 men, aged 18 to 45 years. The sample was recruited from across the country and so represents a range of education and area deprivation levels. An online survey was used to collect data. Results showed that while 39% of respondents correctly identified the age group at highest risk for testicular cancer, only 17% of respondents had ever heard of a testicular self-examination. Analysis revealed knowledge, awareness, and attitudes differed by age groups and area deprivation quintiles. It is recommended that health promoters in Northern Ireland and elsewhere use these findings to tailor health promotion initiatives to engage men and raise testicular cancer and self-examination awareness.

Interest on Large Space Structures (LSS), orbiting in strategic and possibly long-term stable locations, is nowadays increasing in the space community. LSS can serve as strategic outpost to support a variety of manned and unmanned mission, or may carry scientific payloads for astronomical observations. The paper focuses on analysing LSS in the Earth-Moon system, exploring dynamical structures that are available within a multi-body gravitational environment. Coupling between attitude and orbital dynamics is investigated, with particular interest on the gravity gradient torque exerted by the two massive attractors. First, natural periodic orbit-attitude solutions are obtained; a LSS that exploits such solutions would benefit of a naturally periodic body rotation synchronous with the orbital motion, easing the effort of the attitude control system to satisfy pointing requirements. Then, the solar radiation pressure is introduced into the fully coupled dynamical model and its effects investigated, discovering novel periodic attitude solutions. Benefits of periodic behaviours that incorporate solar radiation pressure are discussed, and analysed via the variation of some parameters (e.g reflection/absorption coefficients, position of the centre of pressure). As a final step to refine the current perturbed orbit-attitude model, a structure flexibility is also superimposed to a reference orbit-attitude rigid body motion via a simple, yet effective model. The coupling of structural vibrations and attitude motion is preliminarily explored, and allows identification of possible challenges, that may be faced to position a LSS in a periodic orbit within the Earth-Moon system.

The present study examined the impact of thin-ideal media exposure on Chinese women's drive for thinness, attitudes towards body shape, and eating attitude. Women were assigned to one of two video conditions, which portrayed the thin-ideal (experimental) or was neutral (control group), in terms of content. A total of 83 young women from Hong Kong (N = 38) and Shanghai (N = 45), aged between 18 and 25 years (M age  = 22.7) participated in the study. A significant interaction was observed between the experimental video condition and location. Hong Kong women in the experimental group experienced greater levels of body dissatisfaction than Shanghai women exposed to the same condition. Exposure to thin-ideal media produced an increase in drive for thinness, body dissatisfaction and problematic eating attitudes regardless of location, with a greater immediate impact shown in Hong Kong women.

Full Text Available Abstract Introduction Self-inflicted foreign bodies in the male urethra and urinary bladder are an emergency that urologists may rarely have to face. A case of an electrical wire inserted in the male urethra and coiled in the bladder is presented. Case presentation A 53-year-old male presented with the inability to void and bloody urethral discharge after having introduced an electrical wire in his urethra for masturbation 3 hours earlier. He had made several unsuccessful attempts to remove it. Conclusion The variety of these objects may be impressive and removal of the foreign body may be quite challenging requiring imagination and high-level surgical skills., In this case an electrical wire was used and the diagnostic as well as the therapeutic steps for its removal are presented.

(Relocating (Identity With(in Politicized (Representation of Fe/Male Body in Kamala Das’ Poetry

Sharmin Sultana

2016-04-01

Full Text Available This paper is going to argue that the selected poems of renowned Indian poet Kamala Das are inclined to relocate both feminine and masculine identity through the politicized representation of body.  Kamala Das’ representation of body in her poems has always been viewed as a medium of re-historicizing the pain, sufferings, and psychological trauma that a woman goes through in a patriarchal society.  Though apparently female body seems to be submissive under patriarchal dominance but this paper reveals how female body in Das’ poems acts as a powerful agent over the male body. The objective of this paper is to analyze and evaluate kamala Das’ representation of body to understand the gender reality in a patriarchal society, to question the existing discourse of sexed/gendered identity, to find a new way of viewing to both female and male body. Echoing Beauvoir, Judith Butler and Hall, this paper is going to analyze how Kamala Das represents body as an important factor in her poems to fight back the normative concept of identity based on patriarchal sex and/or gender stereotypes. Keywords: identity, body, sex/gender, performativity, representation

Alternative mating tactics in males of various taxa are associated with body color, body size, and social status. Chameleons are known for their ability to change body color following immediate environmental or social stimuli. In this study, we examined whether the differential appearance of male common chameleon during the breeding season is indeed an expression of alternative mating tactics. We documented body color of males and used computer vision techniques to classify images of individuals into discrete color patterns associated with seasons, individual characteristics, and social contexts. Our findings revealed no differences in body color and color patterns among males during the non-breeding season. However, during the breeding season males appeared in several color displays, which reflected body size, social status, and behavioral patterns. Furthermore, smaller and younger males resembled the appearance of small females. Consequently, we suggest that long-term color change in males during the breeding season reflects male alternative mating tactics. Upon encounter with a receptive female, males rapidly alter their appearance to that of a specific brief courtship display, which reflects their social status. The females, however, copulated indiscriminately in respect to male color patterns. Thus, we suggest that the differential color patterns displayed by males during the breeding season are largely aimed at inter-male signaling. PMID:27409771

This study was conducted to determine the frequency of anabolic-androgenic steroids consumption in male students studying at the university and their awareness, attitude, and role of sports activities; the present descriptive study was conducted on 271 volunteers in 2008. The data collected by self-report questionnaires was analyzed by descriptive inferential statistics. The prevalence of consumption was 3.3%, and it was significantly higher in those with a history of bodybuilding or athletic performance. The overall awareness rate was low, and the attitude was too optimistic. It seems that unawareness, incorrect attitude, and history of athletic performance increases the risk of consumption.

Penis size interacts with body shape and height to influence male attractiveness.

Compelling evidence from many animal taxa indicates that male genitalia are often under postcopulatory sexual selection for characteristics that increase a male's relative fertilization success. There could, however, also be direct precopulatory female mate choice based on male genital traits. Before clothing, the nonretractable human penis would have been conspicuous to potential mates. This observation has generated suggestions that human penis size partly evolved because of female choice. Here we show, based upon female assessment of digitally projected life-size, computer-generated images, that penis size interacts with body shape and height to determine male sexual attractiveness. Positive linear selection was detected for penis size, but the marginal increase in attractiveness eventually declined with greater penis size (i.e., quadratic selection). Penis size had a stronger effect on attractiveness in taller men than in shorter men. There was a similar increase in the positive effect of penis size on attractiveness with a more masculine body shape (i.e., greater shoulder-to-hip ratio). Surprisingly, larger penis size and greater height had almost equivalent positive effects on male attractiveness. Our results support the hypothesis that female mate choice could have driven the evolution of larger penises in humans. More broadly, our results show that precopulatory sexual selection can play a role in the evolution of genital traits.

Interventions have been carried out to improve the reproductive health and status of women in Turkey. However, these efforts are limited due to lack of male involvement. Lifestyle risks such as partner violence need to be evaluated in terms of any effects on the use of contraception. Data collected from interviews of married women and their husbands for the 1998 Turkish Demographic and Health Survey and 1971 husbands were included in the study. The percentage of husbands who were against partner violence was 20.4%. However, 22 (0.9%) husbands had an attitude toward the use of violence against their wives. The frequency of contraceptive use was increased from the group of men who had unfavorable attitudes towards violence to the group of men who had favorable attitudes. A similar trend was found in the percentages of condom use for men, with multiple factors influencing contraceptive use. The study suggests that further investigations are needed for couple-related issues to improve the status of women in the community and to empower women for sexual health.

To explore the beliefs and attitudes towards menstruation of Chinese undergraduates in Hong Kong and to compare those of (1) male and female undergraduates with those of (2) undergraduates studying health-related vs. nonhealth-related programmes. Menstruation is typically viewed as a forbidden topic or a troublesome experience. These negative beliefs and attitudes result from existing myths and taboos associated with cultural factors and health education levels. A cross-sectional survey was conducted in all universities in Hong Kong. Undergraduates were invited through convenience sampling to complete a questionnaire assessing their attitudes and beliefs towards menstruation. A questionnaire on 'beliefs about and attitudes towards menstruation' was adopted. Questionnaires were self-administered by the respondents. A total of 450 questionnaires were distributed, and a response rate of 96.6% was obtained; 416 completed questionnaires were collected and analysed. Many Chinese undergraduates agreed that menstruation is annoying, causes disability, involves prescription and proscription and is not pleasant. When comparing the beliefs and attitudes towards menstruation of Chinese male undergraduates with those of female undergraduates, females tended to disagree that menstruation should be maintained secret, but tended to agree that it was annoying. When comparing the beliefs and attitudes towards menstruation of Chinese undergraduates studying health-related programmes with those under nonhealth-related programmes, the latter group exhibited a higher level of belief in prescription and proscription for menstruation than the former group. Chinese undergraduates in Hong Kong were influenced by the traditional Chinese culture and social environment, resulting in negative attitudes towards menstruation. This study recommends that sex education, especially reproductive health education, be extended to tertiary education. This study provides relevant information on planning

Marathon performance in relation to body fat percentage and training indices in recreational male runners.

Science.gov (United States)

Tanda, Giovanni; Knechtle, Beat

2013-01-01

The purpose of this study was to investigate the effect of anthropometric characteristics and training indices on marathon race times in recreational male marathoners. Training and anthropometric characteristics were collected for a large cohort of recreational male runners (n = 126) participating in the Basel marathon in Switzerland between 2010 and 2011. Among the parameters investigated, marathon performance time was found to be affected by mean running speed and the mean weekly distance run during the training period prior to the race and by body fat percentage. The effect of body fat percentage became significant as it exceeded a certain limiting value; for a relatively low body fat percentage, marathon performance time correlated only with training indices. Marathon race time may be predicted (r = 0.81) for recreational male runners by the following equation: marathon race time (minutes) = 11.03 + 98.46 exp(-0.0053 mean weekly training distance [km/week]) + 0.387 mean training pace (sec/km) + 0.1 exp(0.23 body fat percentage [%]). The marathon race time results were valid over a range of 165-266 minutes.

Recent studies have shown that personal best marathon time is a strong predictor of race time in male ultramarathoners. We aimed to determine variables predictive of marathon race time in recreational male marathoners by using the same characteristics of anthropometry and training as used for ultramarathoners. Anthropometric and training characteristics of 126 recreational male marathoners were bivariately and multivariately related to marathon race times. After multivariate regression, running speed of the training units (β = -0.52, P marathon race times. Marathon race time for recreational male runners may be estimated to some extent by using the following equation (r (2) = 0.44): race time ( minutes) = 326.3 + 2.394 × (percent body fat, %) - 12.06 × (speed in training, km/hours). Running speed during training sessions correlated with prerace percent body fat (r = 0.33, P = 0.0002). The model including anthropometric and training variables explained 44% of the variance of marathon race times, whereas running speed during training sessions alone explained 40%. Thus, training speed was more predictive of marathon performance times than anthropometric characteristics. The present results suggest that low body fat and running speed during training close to race pace (about 11 km/hour) are two key factors for a fast marathon race time in recreational male marathoner runners.

Associations between body morphology, mating success and mate preferences among Slovak males and females.

Prokop, Pavol; Fedor, Peter

2013-01-01

Human body morphology is thought to be correlated with sexual behaviour and sociosexuality (defined as an increased willingness to engage in sex without commitment) influences the perception of certain cues of physical attractiveness. Based on a sample of Slovak university students, we investigated relationships between 1) male and female mating success and reported body morphology (body mass index, BMI and waist-to-hip ratio, WHR) and 2) mate preference characteristics and mating success. Both males and females reported a similar number of long-term sexual partners and frequency of engaging in extra-pair copulation (EPC). The mating success of both sexes was positively mediated by self-perceived attractiveness. However, female BMI was inversely associated with mating success whereas increasing BMI was positively associated with male mating success (the total number of lifetime sexual partners) as well as with the likelihood of engaging in EPC. Unrestricted sociosexuality positively correlated with direct and indirect benefits from mating and negatively with the religious/political background of a potential mate and with the desire for a home/ children. These results confirm the hypothesis that human body morphology is associated with sexual behaviour and that cues of direct/indirect benefits in a potential mate positively correlate with sociosexuality.

Full Text Available Background: Medical male circumcision (MMC is a key strategy in the South African HIV infection prevention package. Women may have a potentially powerful role in supporting such a strategy. Circumcision is not a traditional part of Zulu society, and Zulu women may have limited knowledge and ambivalent or negative attitudes towards MMC. Aim: This study employs quantitative data to expand insight into rural Zulu women’s knowledge of and attitudes towards MMC, and is important as women could potentially yield a powerful positive or negative influence over the decisions of their partners and sons. Setting: A hospital-based antenatal clinic in rural KwaZulu-Natal. Methods: Participants were 590 pregnant, mostly isiZulu-speaking women. Data on their knowledge of and attitude towards MMC were collected using a questionnaire and were analysed descriptively. Results: The majority of the women supported MMC; however, knowledge of the potential benefits was generally poor. Most would encourage their partners and sons to undergo MMC. The preferred place for the procedure was a hospital. Conclusion: Zulu participants supported MMC and would support their partners and children being circumcised. Knowledge around potential benefits was worryingly poor, and further research into disseminating information is essential. The findings highlight the need for an expanded campaign of health education for women, and innovative means are suggested to enhance information accessibility. Reasons for preferring that MMC be carried out in hospital need to be explored further.

Recent interest in male-based sterile insect technique (SIT) and incompatible insect technique (IIT) to control Aedes aegypti and Aedes albopictus populations has revealed the need for an economical, rapid diagnostic tool for determining dispersion and mating success of sterilized males in the wild. Previous reports from other insects indicated rhodamine B, a thiol-reactive fluorescent dye, administered via sugar-feeding can be used to stain the body tissue and seminal fluid of insects. Here, we report on the adaptation of this technique for male Ae. aegypti to allow for rapid assessment of competitiveness (mating success) during field releases. Marking was achieved by feeding males on 0.1, 0.2, 0.4 or 0.8% rhodamine B (w/v) in 50% honey solutions during free flight. All concentrations produced >95% transfer to females and successful body marking after 4 days of feeding, with 0.4 and 0.8% solutions producing the longest-lasting body marking. Importantly, rhodamine B marking had no effect on male mating competitiveness and proof-of-principle field releases demonstrated successful transfer of marked seminal fluid to females under field conditions and recapture of marked males. These results reveal rhodamine B to be a potentially useful evaluation method for male-based SIT/IIT control strategies as well as a viable body marking technique for male-based mark-release-recapture experiments without the negative side-effects of traditional marking methods. As a standalone method for use in mating competitiveness assays, rhodamine B marking is less expensive than PCR (e.g. paternity analysis) and stable isotope semen labelling methods and less time-consuming than female fertility assays used to assess competitiveness of sterilised males.

The purposes of this research were (1) to explore gender differences in the evaluation of physical attractiveness stimuli developed to represent commonly occurring real builds, (2) to identify observers' concepts of physical attractiveness ideals promoted by the media, and (3) to begin cross-validation of these stimuli as representations of observers' concepts of ideal physical attractiveness for male and female builds. Responses included (1) open-ended descriptions of ideal male and ideal female build, (2) ratings of relative attractiveness of 12 male and 15 female stimuli, (3) selections of stimulus types which best represented ideal builds, and (4) selections of stimulus types perceived to be promoted by the media. Analysis showed strong cross-validation among modes of response. Ideal male build included average/balanced type (small and medium), lean/broad-shouldered type (large), and muscular bulk type (medium). Ideal female body build included average/balanced type (small and medium) and lean/broad-shouldered type (small and medium). Gender differences were in emphasis only. Women emphasized lean/broad-shouldered and average/balanced male types. Men emphasized the muscular bulk male type. Body types perceived to be media-promoted highlighted stereotypic male muscularity and female leanness.

Full Text Available The purpose of this cross-sectional observational study was to identify ethnic differences in body composition and obesity-related risk factors between Chinese and white males living in China. 115 Chinese and 114 white male pilots aged 28-63 years were recruited. Fasting body weight, height and blood pressure were measured following standard procedures. Whole-body and segmental body composition were measured using an 8-contact electrode bioimpedance analysis (BIA system. Fasting serum glucose, fasting plasma total cholesterol (TC, high-density lipoprotein (HDL cholesterol, and triglycerides (TG were assessed using automatic biochemistry analyzer. After adjusting for age and body mass index (BMI, Chinese males had significantly higher percentage of body fat (PBF both with respect to whole body (Chinese: 23.7%±0.2% vs. Whites: 22.4%±0.2% and the trunk area (Chinese: 25.0%±0.3% vs. Whites: 23.2%±0.3% compared to their white counterparts. At all BMIs, Chinese males had significantly higher fasting glucose levels (Chinese: 5.7±1.0 mmol/L vs. Whites: 5.2±1.0 mmol/L but lower high-density lipoprotein levels (Chinese: 0.8±1.0 mmol/L vs. Whites: 1.0±1.0 mmol/L than white males. In addition, a marginally significantly higher diastolic blood pressure was found among Chinese men than that among white men (Chinese: 80±1.0 mmHg vs. Whites: 77±1.0 mmHg. Chinese males had more body fat and a greater degree of central fat deposition pattern than that seen in white males in the present study. Furthermore, data on blood pressure, fasting glucose and blood lipids suggest that Chinese men may be more prone to obesity-related risk factors than white men.

Studies of the body size and proportions of athletes have a long history. Comparisons of athletes within specific sports across time, though not extensive, indicate both positive and negative trends. To evaluate secular variation in heights and weights of male youth soccer players reported in studies between 1978 and 2015. Reported mean ages, heights, and weights of male soccer players 9-18 years of age were extracted from the literature and grouped into two intervals: 1978-99 and 2000-15. A third-order polynomial was fitted to the mean heights and weights across the age range for each interval, while the Preece-Baines model 1 was fitted to the grand means of mean heights and mean weights within each chronological year to estimate ages at peak height velocity and peak weight velocity for each time interval. Third-order polynomials applied to all data points and estimates based on the Preece-Baines model applied to grand means for each age group provided similar fits. Both indicated secular changes in body size between the two intervals. Secular increases in height and weight between 1978-99 and 2000-15 were especially apparent between 13 and 16 years of age, but estimated ages at peak height velocity (13.01 and 12.91 years) and peak weight velocity (13.86 and 13.77 years) did not differ between the time intervals. Although the body size of youth soccer players increased between 1978-99 and 2000-15, estimated ages at peak height velocity and peak weight velocity did not change. The increase in height and weight likely reflected improved health and nutritional conditions, in addition to the selectivity of soccer reflected in systematic selection and retention of players advanced in maturity status, and exclusion of late maturing players beginning at about 12-13 years of age. Enhanced training programs aimed at the development of strength and power are probably an additional factor contributing to secular increases in body weight.

Full Text Available Racial disparities in health among African American men in the United States are extensive. In contrast to their White counterparts, African American men have more illnesses and die younger. African American men have colorectal cancer (CRC incidence and mortality rates 25% and 50% higher, respectively, than White men. Due to CRC’s younger age at presentation and high incidence among African American men, CRC screening is warranted at the age of 45 rather than 50, but little is known about younger African American men’s views of CRC screening. Employing survey design, the purpose of the study was to describe the male role norms, knowledge, attitudes, perceived subjective norms, and perceived barriers associated with screening for CRC among a non-random sample of 157 young adult African American men (ages 19-45. Sixty-seven percent of the study sample received a passing knowledge score (85% or better, yet no significant differences were found among the three educational levels (i.e., low, medium, high. More negative attitudes towards CRC screening correlated with the participants’ strong perceptions of barriers, but no extremely negative or positive male role norms and perceived subjective norms were found. The factors significantly associated with attitudes were family history of cancer (unsure, work status, and perceived barriers. Findings from this study provide a solid basis for developing structured health education interventions that address the salient factors shaping young adult African American men's view of CRC and early detection screening behaviors.

Full Text Available Objective: To determine the prevalence, and associated factors of atypical eating attitudes and behaviors in Thai medical students. Methods: A cross-sectional survey examined the eating abnormalities in Thai medical students, conducted in 2014. Research assistants collected data by using; self-reported questionnaires using The Eating Attitudes Test-26 (EAT-26 Thai Version. The statistical analysis used R-program for qualitative variables and logistic regression was applied to determine the correlation and P-value. Results: 141 Thai, medical students (15.9% were reported to have atypical attitudes towards eating, and displayed abnormal eating behaviors. There was no statistically significant correlation of attitude towards eating, and their current eating behaviors according to the medical students’ gender, year of studying and Grade Point Average. However, their eating attitudes and behaviors were, associated with Body Mass index. Normal weight (BMI 18.5- 23.49 and overweight (BMI 23.5-39.9 groups could increase by 2.2 (95% CI =1.2, 4.3 and 2.3 (95% CI=1.1, 4.8 times risk depending on atypical eating attitudes and abnormal eating behaviors respectively, when compared with the underweight group (BMI<18.5. Conclusion: There was no correlated difference in concerns to the Thai medical student’s abnormal eating habits, with gender, years of their study and Grade Point Average. Only normal to over-weight BMI were associated. Overweight male, medical students significantly represented more atypical attitudes towards eating and behaviors than other groups in this population. These results may reveal the changing trends of eating attitudes and behaviors due to the current ideal body image of being more muscular. However, prospective studies are still needed.

Full Text Available Abstract: After performing searches in the main scientific articles database, no specific psychometric scale was found that analyzes body dissatisfaction and body checking to athletes. The aim of the study was to analyze the psychometric properties of the Dissatisfaction and Body Checking in Sports Scale (DBCS - male and female versions - in Brazilian athletes. The researchers built the DBCS. Participants were 1,197 athletes. The exploratory factor analysis showed a factor structure that explained more than 40% of the variance in both versions of the DBCS. The results showed a statistically significant relationship between the DBCS - male and female versions - and questionnaires used for concurrent validity (p .05. The findings indicated difference in DBCS scores according to body fat (p = .01. The results showed a positive relationship between DBCS and Eating Attitudes Test scores (p = .001. It was concluded that the DBCS - male and female versions - demonstrated satisfactory concurrent, discriminant, predictive validity and reproducibility.

Regulation of Caenorhabditis elegans body size and male tail development by the novel gene lon-8

2007-03-01

Full Text Available Abstract Background In C. elegans and other nematode species, body size is determined by the composition of the extracellular cuticle as well as by the nuclear DNA content of the underlying hypodermis. Mutants that are defective in these processes can exhibit either a short or a long body size phenotype. Several mutations that give a long body size (Lon phenotype have been characterized and found to be regulated by the DBL-1/TGF-β pathway, that controls post-embryonic growth and male tail development. Results Here we characterize a novel gene affecting body size. lon-8 encodes a secreted product of the hypodermis that is highly conserved in Rhabditid nematodes. lon-8 regulates larval elongation as well as male tail development. In both processes, lon-8 appears to function independently of the Sma/Mab pathway. Rather, lon-8 genetically interacts with dpy-11 and dpy-18, which encode cuticle collagen modifying enzymes. Conclusion The novel gene lon-8 encodes a secreted product of the hypodermis that controls body size and male ray morphology in C. elegans. lon-8 genetically interacts with enzymes that affect the composition of the cuticle.

The current study aimed to (a) determine the rates of symptoms of muscle dysmorphia (MD), body dysmorphic disorder (BDD), and eating disorder; (b) determine the relationships among symptoms of MD, BDD, and eating disorders; and (c) provide a comprehensive comparison of symptoms of MD, BDD, and eating disorders in a nonclinical population of adult male weightlifters in Australia. The participants (N = 648, mean age = 29.5 years, SD = 10.1) participated in an online survey, consisting of Muscle Appearance Satisfaction Scale, the Body Dysmorphic Disorder Questionnaire, and the Eating Attitude Test-26. Results indicated that 110 participants (17%) were at risk of having MD, 69 participants (10.6%) were at risk of having BDD, and 219 participants (33.8%) were at risk of having an eating disorder. Furthermore, 36 participants (5.6%) were found at risk of having both MD and BDD, and 60 participants (9.3%) were at risk of having both MD and an eating disorder. Significant correlations and associations were found between symptoms of MD and BDD, and symptoms of MD and eating disorders. Support was provided for the comorbidity of, and symptomatic similarities between, symptoms of MD and BDD, and symptoms of MD and eating disorders. This may reflect a shared pathogenesis between symptoms of MD, BDD, and eating disorders. Strength and conditioning professionals, exercise scientists, athletic trainers, and personal trainers should be aware that adult males who are working out with weights (i.e., free weights or machines) may be at increased risk of having MD, BDD, and eating disorders.

Attitudes to body weight, weight gain and eating behavior in pregnancy.

The eating behavior and attitudes to body weight of 100 healthy women were studied 3 days after the birth of their first child. During pregnancy women 'watch their weight' and use a range of methods of weight control which include cigarette smoking and inducing vomiting. During pregnancy 41 women reported weight control problems and 20 women considered their weight and eating problems to be greater than at any previous time. Picking was the most common unwanted behavior. Binge eating was experienced by 44 women, nine of whom reported it to be a 'severe' problem. Although women were ambivalent about being weighed at each antenatal visit, 81 recommended weighing once each month. The women held differing opinions on the effects of breastfeeding on body weight and on the need for nutritional supplements during pregnancy. Women reporting 'disordered eating' were more likely to have antenatal complications and give birth to low birthweight babies. The results suggest good obstetric care should include a history of the woman's eating behavior and body weight.

Body mass changes during ultra-endurance performances have been described for running, cycling and for swimming in a heated pool. The present field study of 20 male and 11 female open-water swimmers investigated the changes in body composition and hydration status during an ultra-endurance event. Body mass, both estimated fat mass and skeletal muscle mass, haematocrit, plasma sodium concentration ([Na+]) and urine specific gravity were determined. Energy intake, energy expenditure and fluid intake were estimated. Males experienced significant reductions in body mass (-0.5 %) and skeletal muscle mass (-1.1 %) (P 0.05). Changes in percent body fat, fat mass, and fat-free mass were heterogeneous and did not reach statistical significance (P > 0.05) between gender groups. Fluid intake relative to plasma volume was higher in females than in males during the ultra-endurance event. Compared to males, females' average increase in haematocrit was 3.3 percentage points (pp) higher, urine specific gravity decrease 0.1 pp smaller, and plasma [Na+] 1.3 pp higher. The observed patterns of fluid intake, changes in plasma volume, urine specific gravity, and plasma [Na+] suggest that, particularly in females, a combination of fluid shift from blood vessels to interstitial tissue, facilitated by skeletal muscle damage, as well as exercise-associated hyponatremia had occurred. To summarise, changes in body composition and hydration status are different in male compared to female open-water ultra-endurance swimmers.

The objective of this study was to develop a socio-sports model of disordered eating (DE) in Brazilian male athletes. Three hundred and twenty one athletes over 12 years of age from 18 different sports modalities were investigated. The Eating Attitudes Test (EAT-26) was applied to evaluate DE. The Body Shape Questionnaire (BSQ) was used to evaluate athlete dissatisfaction with body fat levels. The Muscularity Concern subscale of the Drive for Muscularity Scale (DMS) was used to evaluate athlete dissatisfaction with muscularity levels. To investigate the influence of sociocultural factors on body image, the Sociocultural Attitudes Towards Appearance Questionnaire-3 (SATAQ-3) was applied. Body fat was estimated by skinfold measurement. Demographic data were collected (competitive level and training regimen). Structural equation modelling was conducted to analyse the relationships between research variables and the factors that mediate them. The results indicated that the sociocultural factors and body fat dissatisfaction adhered to socio-sports model of DE (X(2) = 18.50, p = .001, RMSEA = .069, GFI = .97, AGFI = .91, TLI = .93). The BSQ accurately predicted the relationship between SATAQ-3 and EAT-26 (R(2) = .08, p = 0.001) scores. A direct relationship between the SATAQ-3 and EAT-26 (R(2) = .07, p = 0.01) and BSQ (R(2) = .10, p = 0.001) scores was identified. No relationship was found between structural equation model and Muscularity Concern (R(2) = .02, p = 0.14), competitive level (R(2) = .01, p = 0.19), training regimen (R(2) = .03, p = 0.11) or body fat (R(2) = .02, p = 0.14). The results suggest that sociocultural factors and body fat dissatisfaction follow the socio-sports model of DE in Brazilian male athletes. Copyright © 2015 Elsevier Ltd. All rights reserved.

Depression is a major public health concern and often goes untreated. In response to a growing body of research documenting stigma as a barrier to depression care, this study focused on examining public stigma toward potentially vulnerable subpopulations. Participants (N=241) were recruited from Amazon's Mechanical Turk and randomly assigned to provide anonymous ratings on attitudes and feelings of warmth toward pregnant women and expectant fathers experiencing depression, mothers and fathers experiencing postpartum depression, or women and men experiencing depression during nonperinatal periods. Participants reported significantly more negative attitudes about depressed men than women, and male participants reported significantly more negative attitudes than female participants toward depressed individuals. Similarly, participants felt significantly less warmth toward depressed men than women, and male participants expressed significantly less warmth than female participants toward depressed individuals. Male participants felt equally warm toward men and women who experienced depression during nonperinatal periods, whereas female participants felt significantly warmer toward women who experienced depression during nonperinatal periods compared with men. Results indicate that the public views depressed men more negatively than depressed women and that males are more likely to hold stigmatizing attitudes toward depression, suggesting the importance of reducing stigma directed toward men with depression and stigma held by men toward persons with depression. Attitudes and feelings toward depressed individuals did not consistently vary by perinatal status. These findings are an initial step in improving depression treatment engagement strategies and in identifying those who would benefit most from stigma reduction programs.

Vices, gods, and virtues: cosmology as a mediating factor in attitudes toward male homosexuality.

Science.gov (United States)

Hoffman, R J

Using historical and anthropological evidence, the article examines the relationship of the polytheistic and monotheistic cosmologies and attitudes toward sexuality, in particular, male homosexuality. The polytheistic cosmology included the ideas of the continuity of creation, the generative forces of the universe as a whole, and gender blurring in the realm of the supernatural. In the monotheistic cosmology the godhead (Yahweh) is unborn and does not father any generations, the universe is desexualized, and the conception of gender is rigidified. The author concludes that polytheism created the conditions for a wide variety of sexual expression and sex-role behavior and did not preclude any particular form of sexual activity. In contradistinction, the monotheistic cosmology was highly restrictive of permissible male and female behavior and sexual expression and conduct. Consequently, polytheism was able to embrace the crossing of gender lines and homosexual relationships while monotheism was incapable of making these accommodations.

Female masturbation in adolescence and the development of the relationship to the body.

Science.gov (United States)

Laufer, M E

1982-01-01

The significance of the role played by masturbation in the female is examined from a developmental point of view in order to question the assumption, often made, that female masturbation has the same normal significance as masturbation for the male. In order to do so, the difference between attitudes to male and female masturbation is defined as a difference in attitude to the use of the hand for masturbatory activity and is related to the observation that it is that activity that female children give up post-oedipally and again in post-puberty. The unconscious meaning of the hand, as identified with the mother's active handling of the child's body, is examined to show that masturbation is needed by the child to internalize a positive narcissistic cathexis of the body as well as a means of separating from the mother's body. The continued use of the hand during adolescence and adulthood by the girl or woman is then seen as a defensive means of maintaining a positive relationship to her own sexual body once the girl's body has become identified with that of her mother. The failure of this defence when used by the girl as a means to maintain a positive relationship to her own sexual body is seen as leading to the unconsciously determined need to attack her body, as can be observed clinically in those adolescents who physically attack their body.

To elicit information about parents' knowledge, attitudes, and acceptability toward HPV infection and vaccination of male adolescents in Italy; to identify subgroups of this population who exhibit poor knowledge about prevention of HPV infection and reveal negative attitudes toward HPV vaccination in relation to their male sons. Data were collected via self-administered anonymous questionnaire from 1021 parents of males aged 10 to 14 y who were recruited from a random sample of public secondary schools in the South of Italy. Three-quarters (72.6%) reported that the vaccine is a preventive measure for HPV infection and 55.8% that condom use reduces the risk of HPV infection. A high education level, abundant sources of information about HPV infection received from physicians, and knowledge about HPV infection were factors significantly associated with high level of knowledge about preventive measures for HPV infection. 71% revealed their intentions to vaccinate their sons, and this intention was significantly associated with perceived benefits both for HPV vaccination for girls and for childhood recommended vaccinations as well as a need for additional information about HPV vaccination. 53.7% of the eligible parents reported that their daughters had been vaccinated against HPV. Results of the study suggest that the risk of acquiring HPV infection and HPV-related diseases is sorely underestimated. Knowledge on the benefits of adolescents' HPV vaccination in cancer prevention in both sexes should be improved to maximize uptake of HPV vaccination.

Fat is sexy for females but not males: the influence of body reserves on reproduction in snakes (Vipera aspis).

Aubret, Fabien; Bonnet, Xavier; Shine, Richard; Lourdais, Olivier

Reproduction is energetically expensive for both sexes, but the magnitude of expenditure and its relationship to reproductive success differ fundamentally between males and females. Males allocate relatively little to gamete production and, thus, can reproduce successfully with only minor energy investment. In contrast, females of many species experience high fecundity-independent costs of reproduction (such as migration to nesting sites), so they need to amass substantial energy reserves before initiating reproductive activity. Thus, we expect that the relationship between energy reserves and the intensity of reproductive behavior involves a threshold effect in females, but a gradual (or no) effect in males. We tested this prediction using captive vipers (Vipera aspis), dividing both males and females into groups of high versus low body condition. Snakes from each group were placed together and observed for reproductive behavior; sex-steroid levels were also measured. As predicted, females in below-average body condition had very low estradiol levels and did not show sexual receptivity, whereas males of all body condition indices had significant testosterone levels and displayed active courtship. Testosterone levels and courtship intensity increased gradually (i.e., no step function) with body condition in males, but high estradiol levels and sexual receptivity were seen only in females with body reserves above a critical threshold.

Full Text Available Gender roles defined as the patterns of behavior which are approved by society and culture. In other words gender role is the way men and women doing to recognition as feminine and masculine and culture, and society accepted and encourage those behaviors as appropriate behavior for men and women. Present study aimed to study gender role attitude using Islamic gender role attitude scale. A sample of 400 male and female students at public universities including Allameh-Tabataba'i University, Tehran University and the University of Kurdistan was drawn. Respondents were selected using random sampling method and data were collected with questionnaire. Results revealed that there were no traditional gender role attitude among students and all the respondents have professional and liberal attitude toward gender roles. There were significant gender differences between male and female in gender role attitude so that female students have more liberal attitude. In terms of ethnicity there were gender differences in Fars and Lur attitude, so that male have professional and female have liberal attitude. Among Kurdish respondents, male and female have liberal attitude while among Turkish, both male and female have traditional-professional attitude.

Attitude embodiment effects occur when the position or movement of a person's physical body changes the way the person evaluates an object. The present research investigated whether attitude embodiment effects depend more on biomechanical factors or on inferential cues to causal agency. Experiments 1 and 2 showed that actual movements of the physical body are not necessary to create attitude embodiment effects when inferential cues imply agency for another person's physical movements. Experiment 3 showed that actual movements of the physical body are not sufficient to create attitude embodiment effects when inferential cues imply nonagency for those movements. In all 3 experiments, inferential cues to agency played a more important role in attitude embodiment effects than did actual agency, suggesting that theories of embodiment and attitude embodiment need to consider inferential cues to agency alongside biomechanical mechanisms.

Male songbird indicates body size with low-pitched advertising songs.

Body size is a key sexually selected trait in many animal species. If size imposes a physical limit on the production of loud low-frequency sounds, then low-pitched vocalisations could act as reliable signals of body size. However, the central prediction of this hypothesis--that the pitch of vocalisations decreases with size among competing individuals--has limited support in songbirds. One reason could be that only the lowest-frequency components of vocalisations are constrained, and this may go unnoticed when vocal ranges are large. Additionally, the constraint may only be apparent in contexts when individuals are indeed advertising their size. Here we explicitly consider signal diversity and performance limits to demonstrate that body size limits song frequency in an advertising context in a songbird. We show that in purple-crowned fairy-wrens, Malurus coronatus coronatus, larger males sing lower-pitched low-frequency advertising songs. The lower frequency bound of all advertising song types also has a significant negative relationship with body size. However, the average frequency of all their advertising songs is unrelated to body size. This comparison of different approaches to the analysis demonstrates how a negative relationship between body size and song frequency can be obscured by failing to consider signal design and the concept of performance limits. Since these considerations will be important in any complex communication system, our results imply that body size constraints on low-frequency vocalisations could be more widespread than is currently recognised.

Effective implementation requires thathealthcare providers should believe in the procedure’s efficacy and should possess a positiveattitude. A study was undertaken amongst pharmacy and nursing students with differentobjectives.Objectives: To ascertain students’ knowledge, attitudes and perceptions regarding malecircumcision and (HIV prevention.Method: A descriptive cross-sectional study using anonymous questionnaires was undertakenamongst 4th year pharmacy and nursing students studying at a university in KwaZulu-Natal,after obtaining their consent. Data were captured and analysed using SPSS version 15.Results: A response rate of 83.18% and a mean knowledge score of 66.43% with relativelypositive attitudes (62.7 were obtained; 85.4% of the respondents felt that promoting malecircumcision is appropriate, with all Muslim students (n < 11 supporting the promotion ofmale circumcision. Even though all Muslim students supported male circumcision, only 3students were willing to perform the procedure if adequately trained (p < 0.03. The majorityof the female students were unwilling to perform the procedure (p < 0.005. A third of therespondents indicated that male circumcision would both undermine existing protectivebehaviours and strategies as well as increase riskier sexual behaviour. Over 54% of therespondents believed that the South African Health System would be able to cope with themassive male circumcision drive. The majority of the respondents favoured the procedure tobe done at birth. Pain was cited as the most important reason for not wanting to be circumcised.Conclusion: Pharmacy and nursing students have a moderate knowledge of male circumcisionand HIV prevention with relatively positive attitudes. The majority felt that promoting malecircumcision is appropriate and should be encouraged.

Body dissatisfaction is particularly prevalent during adolescence and has recently been linked to stress in females and males. However, prospective studies are needed to better understand the relationship between stress and body dissatisfaction. The present study investigates the direction of this association and the mediating role of self-esteem and body image importance. A sample of 298 adolescent females and males in Grades 7 to 10 (ages 12 to 17 years) were surveyed at two time points over a one-year period. Hierarchical regression analyses revealed that stress significantly predicted body dissatisfaction one year later. Furthermore, a multiple mediation analysis controlling for gender revealed a significant indirect effect in both cross-sectional and longitudinal models, indicating that stress predicts reductions in self-esteem and increases in body importance, which in turn predict body dissatisfaction. These findings suggest that stress, self-esteem, and body importance should be included in programmes aimed at improving body dissatisfaction. Copyright © 2013 Elsevier Ltd. All rights reserved.

SCFA are produced in the gut by bacterial fermentation of undigested carbohydrates. Activation of the Gαi-protein-coupled receptor GPR41 by SCFA in β-cells and sympathetic ganglia inhibits insulin secretion and increases sympathetic outflow, respectively. A possible role in stimulating leptin secretion by adipocytes is disputed. In the present study, we investigated energy balance and glucose homoeostasis in GPR41 knockout mice fed on a standard low-fat or a high-fat diet. When fed on the low-fat diet, body fat mass was raised and glucose tolerance was impaired in male but not female knockout mice compared to wild-type mice. Soleus muscle and heart weights were reduced in the male mice, but total body lean mass was unchanged. When fed on the high-fat diet, body fat mass was raised in male but not female GPR41 knockout mice, but by no more in the males than when they were fed on the low-fat diet. Body lean mass and energy expenditure were reduced in male mice but not in female knockout mice. These results suggest that the absence of GPR41 increases body fat content in male mice. Gut-derived SCFA may raise energy expenditure and help to protect against obesity by activating GPR41.

The effects of a 9-week lower-body plyometric training program on bone mass, bone markers and physical fitness was examined in 51 early pubertal male basketball players divided randomly into a plyometric group (PG: 25 participants) and a control group (CG: 26 participants). Areal bone mineral density (aBMD), bone mineral content (BMC), and bone area (BA) in the whole body, L2-L4 vertebrae, and in total hip, serum levels of osteocalcin (Oc) and C-terminal telopeptide fragment of Type I collagen (CTx), jump, sprint and power abilities were assessed at baseline and 9 weeks. Group comparisons were done by independent student's t-test between means and analyses of (ANOVA) and covariance (ANCOVA), adjusting for baseline values. PG experienced a significant increase in Oc (p BMC and BA in any measured site, except in whole body BMC of the PG. A positive correlation was observed between percentage increase (Δ%) of physical fitness and those of (Oc) for the PG. In summary, biweekly sessions of lower body plyometric training program were successful for improving whole body BMC, bone formation marker (Oc) and physical fitness in early pubertal male basketball players.

Full Text Available Background Adolescents’ perception of their weight is a strong factor in shaping dietary habits and weight control and management. Among non-overweight and overweight adolescents, both overestimation and underestimation of weight status are associated with harmful effects. This study aimed to examine the relationship between perceived weight and attitude toward eating disorders among adolescent girls living in Karaj, Iran. Materials and Methods Involving a two-stage random sampling, this cross-sectional study was conducted on a total of 537 high school girls 14-18 years of age living in Karaj. The Eating Attitudes Test (EAT-26 was employed to screen for attitude toward eating disorders. Also, anthropometric measurements (weight and height, perceived and the ideal weights of the participants were assessed.  Results The average age of girls participating in the study was 16.12±1.20. According to the results, 70% of girls had normal body mass index. It was found that the ideal weight of 55% of the girls in the normal body mass index group fell under the lower than normal boundary. Moreover, the prevalence of eating disorders was estimated to be 23.6%. The attitude toward eating disorder was significantly correlated with body mass index of participants and their self-concept (P

Full Text Available The objective of the present study was to evaluate the supply of a specific-male diet on rooster body weight, hatchability, and fertility. Two diets were supplied during the egg production period: treatment 1, diet formulated for females and containing, in average, 2,830 kcal ME/kg and 15% CP; and treatment 2, diet specifically formulated for male broiler breeders, containing 2,750 kcal ME/kg and 13.5% CP. In the experiment, 26 flocks, with approximately 7,000 females and 840 males each, belonging to the same broiler breeder commercial strain, were distributed into 26 houses (1200m² on the same farm, and submitted to the same management practices. Body weight was evaluated in 13 flocks per treatment and for five weeks (45, 50, 55, 60, 65, and hatchability and fertility in four incubation lots per treatment and for the same weeks. Data were evaluated by the analysis of mixed models for repeated measurements, using the PROC MIXED of SAS 9.3 (SAS Institute Inc., Cary, NC, USA, and means were compared by the test of Tukey-Kramer at 5% significance level. The specific-male diet allowed body weight control during all analyzed weeks and promoted high hatchability and egg fertility. The increase in the number of chicks hatched demonstrates the economic viability of feeding a specific diet for male broiler breeders.

Little is known about how middle-aged and older men are affected by idealized depictions of male singers in music television. A total of 116 males completed pre- and post-test measures of body satisfaction, mood, and social comparison and viewed 5 minutes of clips containing scenery, muscular- or average-looking singers. Negative effects were restricted to young men who viewed the muscular clips. The younger men also reported more comparison while viewing the muscular and average-looking singers compared to the middle-aged and older men. These findings suggest that younger (but not middle-aged or older) men are particularly susceptible to idealized depictions of the male appearance.

Healthcare providers' attitudes toward sexual minorities influence patient comfort and outcomes. This study characterized medical student attitudes toward gay men, focusing on behavior, personhood, gay civil rights, and male toughness. A cross-sectional web-based anonymous survey was sent to medical students enrolled at the University of California, Davis (N = 371) with a response rate of 68%. Few respondents expressed negative attitudes toward gay men or would deny them civil rights. More negative responses were seen with respect to aspects of intimate behavior and homosexuality as a natural form of sexual expression. Men and students younger than 25 years old were more likely to endorse negative attitudes toward behavior as well as more traditional views on male toughness. We show that an important minority of students express discomfort with the behavior of gay men and hold to a narrow construction of male identity. These findings suggest that competency training must move beyond conceptual discussions and address attitudes toward behaviors through new pedagogical approaches.

Full Text Available Anthropologists recognized the tallness of nations in the Dinaric Alps long time ago (Popovic et al, 2013. As the modern Montenegrins fall partly into the Dinaric racial classification (Bjelica et al., 2012, the purpose of this study was to examine the body height in Montenegrin male adolescents from central region as well as the relationship between arm span as an alternative to estimating the body height, which would vary from region to region in Montenegro. Method: Our investigation analyses 548 male adolescents from the central region in Montenegro. The anthropometric measurements were taken according to the protocol of the International Society for the Advancement of Kinanthropometry (ISAK. Means and standard deviations regarding the anthropometric measurements were obtained. A comparison of means of body heights and arm spans within this gender group were carried out using a t-test. The relationships between body height and arm span were determined using simple correlation coefficients and their 95% confidence interval. Then a linear regression analysis was performed to examine the extent to which the arm span can reliably predict body height. Results: The results displayed that male Central-Montenegrins are 183.66±6.93 cm tall and have an arm span of 184.99±8.30cm. Discussion: Compared to other studies, the results of this study have shown that this gender made Central-Macedonians the tall population, taller than general male population in Montenegro (Bjelica et al., 2012. On the other hand, expectably, the arm span reliably predicts body height in this gender. However, the estimation equations which have been obtained in Central-Montenegrins are, different alike in general population, since arm span was closer to body heights (1.33±1.37 centimetres, more than in general population (Bjelica et al., 2012. This confirms the necessity for developing separate height models for each region in Montenegro.

This investigation aimed to study the effects of aflatoxins B 1 +G 1 mixture mainly on total body water (TBW) and on total body solids (TBS) of male albino rats. Some blood components and some reproductive characteristic were also taken into consideration. Two groups, each of 8 male rats were fed the same ration. Rats of one group had been individually ingested daily with a dose of 22 μg B 1 plus 22 μg G 1 for 15 successive weeks. The obtained results showed that aflatoxin administration caused: 1- A decrease in final body weight (FBW), TBW (P<0.01) and TBS (P<0.05). 2- A decrease in serum total proteins (P<0.01), albumin (P<0.05), globulin (P<0.05), glucose (P<0.05) and increase in serum cholesterol, GOT and GPT (P<0.05) activities. 3- A decrease in each of the number of effective matings of males and delivery percentages of females mated with treated males.1 tab

Determining the information content of vocal signals and understanding morphological modifications of vocal anatomy are key steps towards revealing the selection pressures acting on a given species' vocal communication system. Here, we used a combination of acoustic and anatomical data to investigate whether male koala bellows provide reliable information on the caller's body size, and to confirm whether male koalas have a permanently descended larynx. Our results indicate that the spectral prominences of male koala bellows are formants (vocal tract resonances), and show that larger males have lower formant spacing. In contrast, no relationship between body size and the fundamental frequency was found. Anatomical investigations revealed that male koalas have a permanently descended larynx: the first example of this in a marsupial. Furthermore, we found a deeply anchored sternothyroid muscle that could allow male koalas to retract their larynx into the thorax. While this would explain the low formant spacing of the exhalation and initial inhalation phases of male bellows, further research will be required to reveal the anatomical basis for the formant spacing of the later inhalation phases, which is predictive of vocal tract lengths of around 50 cm (nearly the length of an adult koala's body). Taken together, these findings show that the formant spacing of male koala bellows has the potential to provide receivers with reliable information on the caller's body size, and reveal that vocal adaptations allowing callers to exaggerate (or maximise) the acoustic impression of their size have evolved independently in marsupials and placental mammals.

College students are in transition from adolescence to adulthood, and it has been reported that they show poor dietary habits. This study was conducted to compare body image perception, nutrition knowledge, dietary attitudes, dietary habits, and health-related lifestyles between Korean college students (KCS) and Mongolian college students (MCS). Subjects were 314 KCS and 280 MCS. The data includes results of self-administered questionnaires; statistical analysis was performed using the SPSS 23.0 program. With regards to body image perception, KCS perceived themselves to be fatter on current body image than ideal body image compared to MCS; 64.0% of KCS and 34.6% of MCS desired to be thinner. Total score of nutrition knowledge in KCS (17.0) was significantly higher compared to MCS (8.4) ( P correlation with dietary attitudes in MCS ( P mobile phone usage ( P < 0.001), compared to MCS. This study suggests that development of nutrition education program which is effective and proper is required to improve healthy dietary habits among college students of both countries. Essential contents should include acquirement of nutrition knowledge and a motivation for its application to actual life for KCS, and improvement of healthy dietary habits for MCS.

Despite investigations into the rapid increase in eating disorders across diverse ethnic groups, conclusions concerning ethnicity and eating disorders are contradictory. The objective of the present study was to investigate eating attitudes in ethnic Japanese and Caucasian adolescents in Brazil. The influence of body mass index (BMI), menarche and social-affective relationships on the development of eating disorders was also assessed. Questionnaires evaluating the incidence of eating disorders and the influence of social-affective relationships were applied to 544 Japanese-Brazilian and Caucasian adolescent girls: 10 to 11-year-old Japanese-Brazilian (n = 122) and Caucasian (n = 176) pre-menarcheal adolescents, and 16 to 17-year-old Japanese-Brazilian (n = 71) and Caucasian (n = 175) post-menarcheal adolescents. Caucasian girls obtained higher scores on the Eating Attitudes Test (EAT-26), showed greater body image dissatisfaction, dieted more often and had more diet models introduced by their mothers and peers than the Japanese-Brazilian girls. CONCLUSION The Caucasian adolescents overall appeared to be more sensitive to aesthetic and social pressures regarding body image than the Japanese adolescents. The high incidence of EAT-26 scores above 20 in the Caucasian pre-menarcheal group indicates that individual body image concerns are developing at an earlier age. Multiple logistic regression revealed several associations between mother-teen interactions and the development of abnormal eating attitudes.

The use of peer physical examination (PPE) in early clinical skills has been studied amongst medical students. The majority of students are comfortable with using peer physical examination, when sensitive areas are excluded. Students' attitudes are related to their personal characteristics: gender, age, religious faith, and ethnicity. There is no data on nursing students' attitudes to peer physical examination. Identify and explore: Dual cohort, cross-sectional, anonymous survey. Three-year undergraduate nursing programme, skills centre and service clinical learning. All first and third year nursing students were asked to complete a modified Examining Fellow Students questionnaire at the end of 2008. The questionnaire asked students to indicate which of 12 body areas they would not be willing to examine/have examined by a peer of the same/opposite gender. This study also asked students which of the 12 body areas they felt uncomfortable examining on patients. The response rate was 76% (128/168). The students were predominantly female (93% female; 7% male). Most students were comfortable with examining non-sensitive body regions of peers (78.2%-100% willing) and patients (92.3-100% willing). Male gender was significantly associated with willingness to examine and be examined by peers (p=0.001); Asian students were significantly less willing to engage in peer physical examination with opposite gender (pexamining patients of either gender (pexamination shows similarities and differences to other studies. Student characteristics were not related to patient examination attitudes. Copyright © 2012 Elsevier Ltd. All rights reserved.

Obesity is now common and this may have altered visual perceptions of what constitutes a 'normal' and therefore healthy weight. The present study examined cross-cultural differences in male and female participants' ability to visually identify the weight status of photographed Caucasian males. Five hundred and fifty three male and female young adults from the US (high obesity prevalence), UK and Sweden (lower obesity prevalence) participated in an online study. Participants judged the weight status of a series of photographed healthy weight, overweight and obese (class I) Caucasian males and rated the extent to which they believed each male should consider losing weight. There was a strong tendency for both male and female participants to underestimate the weight status of the photographed overweight and obese males. Photographed males were frequently perceived as being of healthier weight than they actually were. Some modest cross-cultural differences were also observed; US participants were worse at recognising obesity than UK participants (p cross-cultural differences were observed for perceptions or attitudes towards the photographed healthy weight or overweight males. The weight status of overweight and obese (class I) Caucasian males is underestimated when judged by males and females using visual information alone. This study provides initial evidence of modest cross-cultural differences in attitudes toward, and the ability to recognise, obesity in Caucasian males.

The relationship between help-seeking attitudes and masculine norms among monozygotic male twins discordant for sexual orientation.

In general, heterosexual men are less favorable to asking for help compared to women and gay men. This can be problematic if a man avoids professional help when he is experiencing significant psychological distress. Yet, it is unclear to what degree such attitudes among men are due to innate differences or social environments. Studying twins provides one avenue for teasing apart these relationships. We recruited 38 pairs of monozygotic male twins (Mage = 35.87 years, SD = 9.52) raised together and who were discordant for sexual orientation. They completed measures of psychological distress (Symptom Checklist-90-Revised), positive attitudes toward psychological help-seeking behavior, and emphasis with fulfilling traditional masculine norms. Contrary to predictions, the heterosexual twins expressed more symptoms of specific distress-hostility (r = .30), paranoid ideation (r = .26), and psychoticism (r = .24)-than their gay cotwins. As predicted, heterosexual men were less favorable to seeking help (r = .25) and expressed greater emphasis on masculine norms (r = .26) than their cotwins. Within each group of men, unique aspects of masculine norms were significantly related to attitudes toward psychological help-seeking behavior. The findings lend credence to the hypothesis that social environments influence attitudes and behaviors that are stereotypically masculine and potentially detrimental to men's health.

A computed torque method based attitude control with optimal force distribution for articulated body mobile robots

International Nuclear Information System (INIS)

Fukushima, Edwardo F.; Hirose, Shigeo

2000-01-01

This paper introduces an attitude control scheme based in optimal force distribution using quadratic programming which minimizes joint energy consumption. This method shares similarities with force distribution for multifingered hands, multiple coordinated manipulators and legged walking robots. In particular, an attitude control scheme was introduced inside the force distribution problem, and successfully implemented for control of the articulated body mobile robot KR-II. This is an actual mobile robot composed of cylindrical segments linked in series by prismatic joints and has a long snake-like appearance. These prismatic joints are force controlled so that each segment's vertical motion can automatically follow the terrain irregularities. An attitude control is necessary because this system acts like a system of wheeled inverted pendulum carts connected in series, being unstable by nature. The validity and effectiveness of the proposed method is verified by computer simulation and experiments with the robot KR-II. (author)

Although aesthetic procedures are known to have a higher impact on women, men are becoming more inclined toward such procedures since the last decade. To determine the reason behind the increase in demand for male aesthetic procedures and to learn about the expectations and inquietude related to body contouring surgery, a prospective questionnaire study was conducted on 200 Turkish males from January 1, 2011-May 31, 2012. Demographic information, previous aesthetic procedures and thoughts on body contouring procedures with given reasons were questioned. The results of the study showed that 53 % of all participants considered undergoing body contouring surgery with the given reason that they believed their current body structure required it. For those who did not consider contouring operations, 92.5 % said they felt that they did not need such a procedure. The results of the statistical analysis showed that BMI was a significant factor in the decision making process for wanting to undergo body contouring procedures. The results of the study showed that men's consideration for aesthetic operations depends mainly on necessity and that the most considered region was the abdominal zone in regard to contouring. We can conclude that men are becoming more interested in body contouring operations and therefore different surgical procedures should be refined and re-defined according to the expectations of this new patient group.

The estimated energy requirement is important for adequate nutritional management in athletes. The energy requirement can be estimated from the basal metabolic rate (BMR). However, there is little data regarding the BMR of Japanese athletes. This study measured the BMR and body composition of 81 elite Japanese male athletes in different sports categories: endurance (E), strength, power and sprint (S) and ball game (B). The factors influencing the BMR were also investigated. The BMR and body composition were measured by indirect calorimetry and an air-displacement plentysmograph device (the BOD POD), respectively. The BMR per lean body mass (LBM) differed significantly among the three groups. The BMR was significantly correlated with the body weight (BW) and LBM in all groups. A multiple-regression analysis showed that the LBM was the most powerful predictor in the E and S groups, whereas the BW was the most powerful predictor in the B group. The BW appears to become an important predictor as the BW of athletes increases. Additionally, height was the second explanatory variable in the S and B groups, thus suggesting that height needs to be considered for the BMR in these groups. Therefore, the BMR in elite athletes needs to be estimated according to their body composition.

2016-01-01

The purpose of this study was to examine the predictive influence that internalization of society and media messages has on body dissatisfaction, as well as the prediction influence that body dissatisfaction has on disordered eating behaviors, such as preoccupation with weight, dieting, and eating restraint. A total of 324 participants completed the demographic questionnaire, the Multidimensional Body Self Relations Questionnaire (Cash, 2001 ), the Sociocultural Attitudes Towards Appearance Questionnaire (Heinberg, Thompson, & Stormer, 1995 ) for women, and the Sociocultural Attitudes Towards Appearance Questionnaire-Revised-Male-Version (Cusumano & Thompson, 1997 ) for men, and the locus of control (Rotter, 1966 ). The results of this study found that high internalization leads to body dissatisfaction, in turn, leading to disordered eating behaviors, such as preoccupation with weight, dieting, and eating restraint. This study proposes the implementation of media literacy and education programs that teach college women and men, girls and boys, to think more critically about the media.

2009-01-01

The aim of this research is twofold: 1) to determine attitudes of high school students toward addictive substances; and 2) to determine students' attitudes toward addictive substances in terms of some variables including gender, grade, and perceived parental attitudes. To this end, Addictive Substances Attitudes Scale and Parental Attitudes Scale were given to a sample of 745 high school students (F = 330, M = 415) chosen by purposive sampling method. Results showed that compared to the males, females had more negative attitudes toward addictive substances. And compared to students from the upper grades, students from lower grades had more negative attitudes toward addictive substances. It is also found that students' attitudes toward addictive substances correlate with perceived parental attitudes. The correlation is low and positive for perceived democratic parental attitudes (r = .29), negative and low for perceived authoritarian parental attitudes (r = -.27).

Griffiths, Scott; Angus, Douglas; Murray, Stuart B; Touyz, Stephen

2014-03-01

Research on emotional functioning, body dissatisfaction, and disordered eating in males is predominated by studies of negative affect and emotion regulation. Other aspects of emotional functioning, namely emotion recognition and attentional biases toward emotional stimuli, have received little empirical attention. The present study investigated the unique associations between different aspects of men's emotional functioning and their disordered eating attitudes, muscularity dissatisfaction, and body fat dissatisfaction. Results from 132 male undergraduates showed that muscularity dissatisfaction was uniquely associated with both emotion regulation difficulties and an attentional bias toward rejecting faces. Body fat dissatisfaction was not uniquely associated with any aspect of emotional functioning. Disordered eating was uniquely associated with emotion regulation difficulties. Collectively, the results indicate differences in the patterns of associations between men's emotional functioning and their body dissatisfaction and disordered eating. Copyright © 2013 Elsevier Ltd.

The results displayed that male Southern-Montenegrins are 182.53±7.53 cm tall and have an arm span of 184.55±9.03 cm. Compared to other studies, the results of this study have shown that this gender made Southern- Montenegrins the tall population, taller than most of nation around the Europe. On the other hand, expectably, the arm span reliably predicts body height in this gender. However, the estimation equations which have been obtained in Southern-Montenegrins are, different alike in general population, since arm span was closer to body heights (2.03±1.50 cm, more than in general population. Hence, this study also confirms the necessity for developing separate height models for each region in Montenegro.

Knowing and, if necessary, altering competitive athletes' real attitudes towards the use of banned performance-enhancing substances is an important goal of worldwide doping prevention efforts. However athletes will not always be willing to reporting their real opinions. Reaction time-based attitude tests help conceal the ultimate goal of measurement from the participant and impede strategic answering. This study investigated how well a reaction time-based attitude test discriminated between athletes who were doping and those who were not. We investigated whether athletes whose urine samples were positive for at least one banned substance (dopers) evaluated doping more favorably than clean athletes (non-dopers). We approached a group of 61 male competitive bodybuilders and collected urine samples for biochemical testing. The pictorial doping Brief Implicit Association Test (BIAT) was used for attitude measurement. This test quantifies the difference in response latencies (in milliseconds) to stimuli representing related concepts (i.e. doping-dislike/like-[health food]). Prohibited substances were found in 43% of all tested urine samples. Dopers had more lenient attitudes to doping than non-dopers (Hedges's g = -0.76). D-scores greater than -0.57 (CI95 = -0.72 to -0.46) might be indicative of a rather lenient attitude to doping. In urine samples evidence of administration of combinations of substances, complementary administration of substances to treat side effects and use of stimulants to promote loss of body fat was common. This study demonstrates that athletes' attitudes to doping can be assessed indirectly with a reaction time-based test, and that their attitudes are related to their behavior. Although bodybuilders may be more willing to reveal their attitude to doping than other athletes, these results still provide evidence that the pictorial doping BIAT may be useful in athletes from other sports, perhaps as a complementary measure in evaluations of

Inter-professional collaboration between physicians and nurses, within and between cultures, can help contain cost and insure better patient outcomes. Attitude toward such collaboration is a function of the roles prescribed in the culture that guide professional behavior. The purpose of the study was to test three research hypotheses concerning attitudes toward physician-nurse collaboration across genders, disciplines, and cultures. The Jefferson Scale of Attitudes Toward Physician-Nurse Collaboration was administered to 639 physicians and nurses in the United States (n = 267) and Mexico (n = 372). Attitude scores were compared by gender (men, women), discipline (physicians, nurses), and culture (United States, Mexico) by using a three-way factorial analysis of variance design. Findings confirmed the first research hypothesis by demonstrating that both physicians and nurses in the United States would express more positive attitudes toward physician-nurse collaboration than their counterparts in Mexico. The second research hypothesis, positing that nurses as compared to physicians in both countries would express more positive attitudes toward physician-nurse collaboration, was also supported. The third research hypothesis that female physicians would express more positive attitudes toward physician-nurse collaboration than their male counterparts was not confirmed. Collaborative education for medical and nursing students, particularly in cultures with a hierarchical model of inter-professional relationship, is needed to promote positive attitudes toward complementary roles of physicians and nurses. Faculty preparation for collaboration is necessary in such cultures before implementing collaborative education.

2015-09-01

The purpose of this study was to examine relationships among bodybuilding dependence, muscle satisfaction, body image-related quality of life and body image-related coping strategies, and test the hypothesis that muscle dysmorphia characteristics may predict quality of life via coping strategies. Participants (294 males, Mage=20.5 years, SD=3.1) participated in a cross-sectional survey. Participants completed questionnaires assessing muscle satisfaction, bodybuilding dependence, body image-related quality of life and body image-related coping. Quality of life was correlated positively with muscle satisfaction and bodybuilding dependence but negatively with body image coping (P<0.05). Body image coping was correlated positively with bodybuilding dependence and negatively with muscle satisfaction (P<0.05). Mediation analysis found that bodybuilding dependence and muscle satisfaction predicted quality of life both directly and indirectly via body image coping strategies (as evidenced by the bias corrected and accelerated bootstrapped confidence intervals). These results provide preliminary evidence regarding the ways that muscularity concerns might influence body image-related quality of life. Copyright © 2014 Sports Medicine Australia.

Competition between adult males for limited resources such as food and receptive females is shaped by the male pattern of pituitary growth hormone (GH) secretion that determines body size and the production of urinary pheromones involved in male-to-male aggression. In the brain, dopamine (DA) provides incentive salience to stimuli that predict the availability of food and sexual partners. Although the importance of the GH axis and central DA neurotransmission in social dominance and fitness is clearly appreciated, the two systems have always been studied unconnectedly. Here we conducted a cell-specific genetic dissection study in conditional mutant mice that selectively lack DA D2 receptors (D2R) from pituitary lactotropes (lacDrd2KO) or neurons (neuroDrd2KO). Whereas lacDrd2KO mice developed a normal GH axis, neuroDrd2KO mice displayed fewer somatotropes; reduced hypothalamic Ghrh expression, pituitary GH content, and serum IGF-I levels; and exhibited reduced body size and weight. As a consequence of a GH axis deficit, neuroDrd2KO adult males excreted low levels of major urinary proteins and their urine failed to promote aggression and territorial behavior in control male challengers, in contrast to the urine taken from control adult males. These findings reveal that central D2Rs mediate a neuroendocrine-exocrine cascade that controls the maturation of the GH axis and downstream signals that are critical for fitness, social dominance, and competition between adult males.

We hypothesize that conjugated linoleic acid (CLA) may be effective in preventing the changes in total and regional body composition and increases in interleukin (IL) 6 that occur as a result of hypogonadism. Male guinea pigs (n = 40, 70- to 72-week retired breeders) were block randomized by weight into 4 groups: (1) sham surgery (SHAM)/control (CTRL) diet, (2) SHAM/conjugated linoleic acid (CLA) diet (1%), (3) orchidectomy (ORX)/CTRL diet, and (4) ORX/CLA diet. Dual-energy x-ray absorptiometry scans were performed at baseline and week 16 to assess body composition. Serum IL-6 was analyzed using an enzyme-linked immune sorbent assay. Fatty acids (FAs) from visceral and subcutaneous adipose tissue were analyzed using gas chromatography. In ORX/CTRL guinea pigs, percent total body fat increased by 6.1%, and percent lean mass decreased by 6.7% over the 16-week treatment period, whereas no changes were observed for either parameter in ORX/CLA guinea pigs. Guinea pigs fed the CLA diet gained less percent total, upper, and lower body fat than those fed the CTRL diet regardless of surgical treatment. Regional adipose tissue FA composition was reflective of dietary FAs. Serum IL-6 concentrations were not different among groups. In this study, we observed that, in male guinea pigs, hypogonadism resulted in increased fat mass and decreased lean mass. In addition, CLA was effective in reducing gains in body fat and maintaining lean mass in both hypogonadal and intact guinea pigs. Copyright © 2016 Elsevier Inc. All rights reserved.

The high prevalence and potential side effects of anabolic-androgenic steroids (AAS) misuse by athletes has made it a major public health concern. Epidemiological studies on the abuse of such drugs are mandatory for developing effective preventive drug control programs in sports community. This study aimed to investigate the prevalence of AAS abuse and their association with some psycho-socio-demographic factors in Iranian male recreational body-builders. Between March and October 2011; 906 recreational male body-builders from 103 randomly selected bodybuilding clubs in Tehran, Iran were participated in this study. Some psycho-socio- demographic factors including age, job, average family income, family size, sport experience (months), weekly duration of the sporting activity (h), purpose of participation in sporting activity, mental health as well as body image (via General Health Questionnaire and Multidimensional Body-Self Relations Questionnaire, respectively), and history of AAS use were obtained by interviews using questionnaires. Participants were all recreational male body-builders [mean age (SD): 25.7 (7.1), ranging 14-56 yr]. Self-report of AAS abuse was registered in 150 body-builders (16.6%). Among different psycho-socio-demographic factors, only family income and sport experience were inversely associated with AAS abuse. Lifetime prevalence of AAS abuse is relatively high among recreational body-builders based on their self-report. Some psycho-socio-demographic factors including family income and sport experience may influence the prevalence of AAS abuse.

Some dynamics of male chauvinism.

Science.gov (United States)

Woods, S M

1976-01-01

Male chauvinism was studied in the psychoanalytic therapy of 11 men. It refers to the maintenance of fixed beliefs and attitudes of male superiority, associated with overt or covert depreciation of women. Challenging chauvinist attitudes often results in anxiety or other symptoms. It is frequently not investigated in psychotherapy because it is ego-syntonic, parallels cultural attitudes, and because therapists often share similar bias or neurotic conflict. Chauvinism was found to represent an attempt to ward off anxiety and shame arising from one or more of four prime sources: unresolved infantile strivings and regressive wishes, hostile envy of women, oedipal anxiety, and power and dependency conflicts related to masculine self-esteem. Mothers were more important than fathers in the development of chauvinism, and resolution was sometimes associated with decompensation in wives.

Particular strategies of media advocacy can help people contest the dominant body images of fashion advertisements and reframe them to include a broader array of "normal" images. A study with an intervention group (n = 60) and a comparison group (n = 45) of undergraduate college students was conducted to investigate whether analyzing and reframing fashion advertisements changed the students' attitudes and behaviors regarding their own body images. Results from the posttest showed a significant change in beliefs among those in the intervention group but no significant change in behaviors. The comparison group showed no significant change in beliefs or behaviors. Posttest results from the women in the intervention group (n = 44) indicated a significant change in the study participants' beliefs that adult models in advertisements have an ideal body size and shape and that the participants' decisions about dieting or exercising should be based more on looks rather than on health status.

Context • Interest has been rising in the use of complementary and alternative medicine (CAM) for the promotion of health and treatment of disease. To date, the majority of CAM research has focused on exploring the demographic characteristics, attitudes, and motivations of CAM users and on the efficacy of different therapies and products. Less is known with respect to the psychological characteristics of people who use CAM. Previous research has not investigated the usefulness of integrating mind-body therapies with natural products in a combined mood intervention. Objective • The study intended to investigate attitudes toward a proposed new approach to the treatment of mood, one that integrates psychological mind-body therapies and natural nutritional products. Design • Participants completed an online survey covering demographics, personality traits, locus of control, use of CAM, attitudes toward the proposed psychonutritional approach, and mood. Setting • This study was conducted at the University of Adelaide School of Psychology (Adelaide, SA, Australia). Participants • Participants were 333 members of the Australian general public, who were recruited online via the social-media platform Facebook. The majority were women (83.2%), aged between 18 and 81 y. Outcome Measures • Measures included the Multidimensional Health Locus of Control Scale Form B, the Ten-Item Personality Inventory, and the Depression, Anxiety and Stress Scale. Results • Participants were positive about the proposed approach and were likely to try it to enhance their moods. The likeliness of use of the combined approach was significantly higher in the female participants and was associated with higher levels of the personality trait openness and an internal health locus of control, after controlling for all other variables. Conclusions • Interest exists for an intervention for mood that incorporates both psychological and nutritional approaches. Further research into the

This study investigates Italian adolescents' attitudes toward gay men and lesbians and same-sex marriage, and their beliefs about the origins of homosexuality. The sample consists of 449 subjects (226 males), aged between 14 and 21 years. The principal instruments used are: the Attitudes Toward Lesbians and Gay men (ATLG), the Modern Homonegativity Scale (MHS), and the Attitudes Toward Same-Sex Marriage (ATSM). Results suggest that males show a more negative attitude than females toward homosexuals. Furthermore data reveal that respondents with a lack of personal direct contact with gay people have less positive attitudes toward homosexual people and same-sex marriage. The data in this study suggest that homophobia could be deeply rooted in a traditional value system that refutes gender equality.

Full Text Available ABSTRACT The purpose of this study was to determine live weight and body measurements of male and female native ducks raised in different raising systems. One hundred and twenty native ducks (60 males, 60 females were used in the study. The ducks were raised in deep litter floor and cage systems. Live weight and body values were measured every two weeks, until they were 56 days old. Three-parameter logistic regression and Gompertz model were used to determine growth model of male and female ducks. Interactions of time-raising system and time-sex were statistically significant in terms of live weight. At the end of eight weeks, live weights of ducks raised in deep litter floor were higher than ducks raised in cage system. In addition, live weights of male ducks were higher than female ducks. Consequently, deep litter floor is more appropriate for live weight in native ducks. Accuracy rate of Three-parameter Logistic and Gompertz models for estimation of growth in ducks was between 0.91-0.95 and similar results were obtained from both models. The Gompertz model is appropriate for the data structure of this study because it contains fewer iterations than the Three-Parameter Logistic model.

Full Text Available This study focuses on representations of the body and religion in Nordic film. The aim is to illustrate the kinds of representations of religion and the body that can be found in contemporary Nordic films, demonstrate how these representations relate to religion, the body and film more generally, and explore what perceptions of and attitudes to the body and religion the representations suggest. The analysis begins with an introduction to religion and film studies, religion in Nordic film and the themes and films chosen for this study. After this a short overview of earlier studies dealing with the body, film, and religion is presented, before delving into the issue of the body and religion in Nordic film. The article is concluded by reflecting on the more over-arching ideas and attitudes that the material can be argued to point to and the possible changes and challenges the films express.

The moderating effect of gender role on the relationships between gender and attitudes about body and eating in a sample of Italian adolescents.

Lampis, J; Cataudella, S; Busonera, A; De Simone, S; Tommasi, M

2017-03-13

The differential prevalence of eating disorders in males and females can be explained by the impact of gender-role orientations. Inside the Italian socio-cultural context, gender socialization can be influenced by stereotypical gender beliefs, and this may contribute to the psychological distress of individuals who identify with discrepant gender roles from their biological sex. Our study explored, within the Italian context, the potential moderating effect of masculinity and femininity on the relationships between gender and attitudes about body and eating. Nine hundred and twenty Italian male and female adolescents (M = 427, F = 493; age 14-21 years) completed the Eating Disorder Inventory-2 (EDI-2) and the Bem Sex-Role Inventory (BSRI). A moderating effect of gender role on the relationship between gender and bulimia, and drive of thinness emerged. Girls with higher levels of masculinity scored higher on bulimia than did their counterparts with lower levels, and boys with higher levels of femininity scored higher on bulimia and on drive for thinness than did their counterparts with lower levels. Data did not reveal a moderating effect of gender role on the relationship between gender and body satisfaction. Our data suggest that adolescents who endorsed a gender role that is socially considered discrepant from their biological sex (girls with higher levels of masculinity and boys with higher levels of femininity) are more likely to show higher level of bulimia and drive of thinness. This suggests the need for prevention and treatment programmes for eating disorders that take into account individuals' gender-role orientation and the influence that culturally dominant gender beliefs can exert on it.

These studies examined the differences in sweet taste perception and implicit attitude toward sweet between normal-weight and overweight/obese adults; and tested the effects of soft drink consumption on sweet taste, explicit preference and implicit attitude toward sweet in normal-weight subjects. In study 1, normal-weight (n = 22) and overweight/obese (n = 11) adults were assessed for sweet taste intensity and pleasantness. Implicit attitude toward sweet was assessed by implicit association test (IAT). In study 2, normal-weight, lightly active adults (n = 12) underwent one month soft drink supplementation (≈760 ml/day). This increased their daily carbohydrate intake by 2.1 ± 0.2g/kg body weight. Sweet taste perception, explicit preference and implicit attitudes to sweet were assessed. In both studies salty taste was also assessed as a contrasting perception. Overweight/obese subjects perceived sweet and salty tastes as less intense (-23% and -19%, respectively) and reported higher IAT scores for sweet than normal-weight controls (2.1-fold). The supplementation changed sweet intensity/pleasantness ratings and it increased explicit preference (2.3-fold) for sweet in a subgroup of initial sucrose-dislikers. In conclusion, overweight/obese individuals are more implicitly attracted to sweet. One month of soft drink supplementation changed sweet taste perception of normal-weight subjects.

Eating disorders are common health issues among the adolescents. The objective of this study was to determine the prevalence of eating disorders and their relationship with body mass index, body part satisfaction and perception on body weight among urban secondary school children. It was a cross-sectional study conducted in Kuching, Sarawak. Data was collected using a self-administered questionnaire that consist of the Eating Attitude Test-26 (EAT-26), perception on body part satisfaction and body weight, and anthropometric measurement. Data was entered and analysed using SPSS version 22. A total of 329 respondents participated in this study with 59% females and 60.5% Malays. There were 14.3% of the respondents overweight and obese, with higher percentage among males (19.3%). About 18.5% of the respondents were found to be at risk of eating disorders with higher prevalence among males (19.3%). More females reported to have higher prevalence of body part dissatisfaction (46.9%) and body weight (37.6%) compared to males (40%, 28.1%). The statistical results indicated there were significant associations between EAT-26 and body mass index (BMI) (p=0.039), body part satisfaction (p=0.004), and perception of body weight (p=0.038). Eating disorders are becoming more prevalent amongst adolescents, particularly among males. As eating disorder are strongly associated with adolescent mental and physical health, intervention programme on their developmental challenges and issues for both males and females should be in place particularly in the school education syllabus.

Full Text Available To identify the differences and similarities in sexual and contraceptive knowledge, attitudes, and behavior among Latino male adolescent students living in California and Lima. Self-administered, anonymous surveys were completed by Latino male students aged 12-19 participating in California, and by male adolescent students in four high schools in Lima. Both surveys contained similar questions allowing for comparisons regarding sexual activity and contraceptive behavior. The mean age of male students were 16 and 15 years, respectively. More California males reported having engaged in sexual intercourse (69% vs 43%. The sexual debut was 13 years in both samples. More students in California were aware of their risk of pregnancy at first sexual intercourse than in Lima (82% vs 50%. One-third of the California males reported communicating with their partner about sex and contraception to be "easy" as compared to 53% of males in Lima. More students in California reported knowing a place to obtain contraceptives if they need them (85% vs 63%, having ever gotten someone pregnant (29% vs 7%, and having fathered a child (67% vs 16%.

1994-03-01

As part of a community based educational campaign to convey the risk of HIV infection and AIDS to commercial sex workers in Jakarta, over 600 male transvestites (WARIA) were questioned about their sexual behavior patterns and their knowledge and attitude towards HIV infection and AIDS. Most expressed a genuine fear about AIDS, but they stated they did not have sufficient information to determine if their risk of infection, at this time, was great enough to command a change in their sexual conduct. Among the group who felt they were not at risk for HIV infection, 40% had 8 or more different sex partners per week. Low risk receptive oral sex, thigh massage (simulated vaginal sex) and masturbation of the client were routine activities but high risk receptive anal sex without condoms was most common. Despite such high risk behavior, the WARIA community remains free of HIV infections. However, if they refuse to accept the endorsement of their peer leaders and they fail to alter their sexual behavior because of an unawareness of their risk, that status will change soon.

Background Knowing and, if necessary, altering competitive athletes’ real attitudes towards the use of banned performance-enhancing substances is an important goal of worldwide doping prevention efforts. However athletes will not always be willing to reporting their real opinions. Reaction time-based attitude tests help conceal the ultimate goal of measurement from the participant and impede strategic answering. This study investigated how well a reaction time-based attitude test discriminated between athletes who were doping and those who were not. We investigated whether athletes whose urine samples were positive for at least one banned substance (dopers) evaluated doping more favorably than clean athletes (non-dopers). Methods We approached a group of 61 male competitive bodybuilders and collected urine samples for biochemical testing. The pictorial doping Brief Implicit Association Test (BIAT) was used for attitude measurement. This test quantifies the difference in response latencies (in milliseconds) to stimuli representing related concepts (i.e. doping–dislike/like–[health food]). Results Prohibited substances were found in 43% of all tested urine samples. Dopers had more lenient attitudes to doping than non-dopers (Hedges’s g = -0.76). D-scores greater than -0.57 (CI95 = -0.72 to -0.46) might be indicative of a rather lenient attitude to doping. In urine samples evidence of administration of combinations of substances, complementary administration of substances to treat side effects and use of stimulants to promote loss of body fat was common. Conclusion This study demonstrates that athletes’ attitudes to doping can be assessed indirectly with a reaction time-based test, and that their attitudes are related to their behavior. Although bodybuilders may be more willing to reveal their attitude to doping than other athletes, these results still provide evidence that the pictorial doping BIAT may be useful in athletes from other sports

Computational phantoms are commonly used in internal radiation dosimetry to assess the amount and distribution pattern of energy deposited in various parts of the human body from different internal radiation sources. Radiation dose assessments are commonly performed on predetermined reference computational phantoms while the argument for individualized patient-specific radiation dosimetry exists. This study aims to evaluate the influence of body habitus on internal dosimetry and to quantify the uncertainties in dose estimation correlated with the use of fixed reference models. The 5-year-old IT’IS male phantom was modified to match target anthropometric parameters, including body weight, body height and sitting height/stature ratio (SSR), determined from reference databases, thus enabling the creation of 125 5-year-old habitus-dependent male phantoms with 10th, 25th, 50th, 75th and 90th percentile body morphometries. We evaluated the absorbed fractions and the mean absorbed dose to the target region per unit cumulative activity in the source region (S-values) of F-18 in 46 source regions for the generated 125 anthropomorphic 5-year-old hybrid male phantoms using the Monte Carlo N-Particle eXtended general purpose Monte Carlo transport code and calculated the absorbed dose and effective dose of five 18F-labelled radiotracers for children of various habitus. For most organs, the S-value of F-18 presents stronger statistical correlations with body weight, standing height and sitting height than BMI and SSR. The self-absorbed fraction and self-absorbed S-values of F-18 and the absorbed dose and effective dose of 18F-labelled radiotracers present with the strongest statistical correlations with body weight. For 18F-Amino acids, 18F-Brain receptor substances, 18F-FDG, 18F-L-DOPA and 18F-FBPA, the mean absolute effective dose differences between phantoms of different habitus and fixed reference models are 11.4%, 11.3%, 10.8%, 13.3% and 11.4%, respectively.

Negative attitudes of heterosexual people toward same-sex marriage relate to the degree to which they are homophobic. However, it has been understudied whether there exists a gender difference in this association. Our results indicated that homophobia was the best predictor of attitudes toward gay male and lesbian marriage, and this was equally true for both heterosexual men and women. However, the attitudinal difference between gay male and lesbian marriage was related to homophobia in men but not in women. That is, for men only, being less homophobic toward lesbians than toward gay men was associated with favoring lesbian over gay men marriage. Considering these results, the role of gender in attitudes toward same-sex marriage seems to be as an important moderator of homophobia.

Although studies have begun to shed light on medical students' attitudes towards peer physical examination (PPE), they have been conducted at single sites, and have generally not examined changes in medical students' attitudes over time. Employing both cross-sectional and longitudinal designs, the current study examines medical students' attitudes towards PPE at schools from different geographical and cultural regions and assess changes in their attitudes over their first year of medical study. Students at six schools (Peninsula, UK; Durham, UK; Auckland, New Zealand; Flinders, Australia; Sapporo, Japan and Li Ka Shing, Hong Kong) completed the Examining Fellow Students (EFS) questionnaire near the start of their academic year (T1), and students at four schools (Peninsula, Durham, Auckland and Flinders) completed the EFS for a second time, around the end of their academic year (T2). Univariate and multivariate analyses revealed a high level of acceptance for PPE of non-intimate body regions amongst medical students from all schools (greater than 83%, hips, at T1 and 94.5%, hips and upper body, at T2). At T1 and T2, students' willingness to engage in PPE was associated with their gender, ethnicity, religiosity and school. Typically, students least comfortable with PPE at T1 and T2 were female, non-white, religious and studying at Auckland. Although students' attitudes towards PPE were reasonably stable over their first year of study, and after exposure to PPE, we did find some statistically significant differences in attitudes between T1 and T2. Interestingly, attitude changes were consistently predicted by gender, even when controlling for school. While male students' attitudes towards PPE were relatively stable over time, females' attitudes were changeable. In this paper, we discuss our findings in light of existing research and theory, and discuss their implications for educational practice and further research.

Weight gain and body fat increase the risk of cardiometabolic disease. Cross-sex hormone therapy in transgender persons leads to changes in body weight and body composition, but it is unclear to what extent. We performed a meta-analysis to investigate the changes in body weight, body fat and lean body mass during cross-sex hormone therapy in transgender persons. We searched the PubMed database for eligible studies until November 2015. Ten studies reporting changes in body weight, body fat or lean mass in hormone naive transgender persons were included, examining 171 male-to-female and 354 female-to-male transgender people. Pooled effect estimates in the male-to-female group were +1.8 kg (95% CI: 0.2;3.4) for body weight, +3.0 kg (2.0;3.9) for body fat and -2.4 kg (-2.8; -2.1) for lean body mass. In the female-to-male group, body weight changed with +1.7 kg (0.7;2.7), body fat with -2.6 kg (-3.9; -1.4) and lean body mass with +3.9 kg (3.2;4.5). Cross-sex hormone therapy increases body weight in both sexes. In the male-to-female group, a gain in body fat and a decline in lean body mass are observed, while the opposite effects are seen in the female-to-male group. Possibly, these changes increase the risk of cardiometabolic disease in the male-to-female group. © 2016 Blackwell Verlag GmbH.

Overweight and obesity are associated with increased risk of chronic diseases and mortality. Exercise capacity is inversely associated with mortality risk. However, little is known on the interaction between fitness, fatness, and mortality risk in hypertensive individuals. Thus, we assessed the interaction between exercise capacity, fatness, and all-cause mortality in hypertensive males. A graded exercise test was performed in 4,183 hypertensive veterans (mean age ± s.d.; 63.3 ± 10.5 years) at the Veterans Affairs Medical Center, Washington, DC. We defined three body weight categories based on body mass index (BMI): normal weight (BMI 7.5 METs). During a median follow-up period of 7.2 years, there were 1,000 deaths. The association between exercise capacity and mortality risk was strong, inverse, and graded. For each 1-MET increase in exercise capacity the adjusted risk was 20% for normal weight, 12% for overweight, and 25% for obese (P exercise capacity is associated with lower mortality risk in hypertensive males regardless of BMI. The risk for overweight and obese but fit individuals was significantly lower when compared to normal weight but unfit. These findings suggest that in older hypertensive men, it may be healthier to be fit regardless of standard BMI category than unfit and normal weight.

Full Text Available According to Inglehart's modernisation theory, socio-economic growth leads to changes in values. Following a longer period of economic growth, a gradual change from materialistic to post-materialistic values is established. The main goal of this study, which is based on Inglehart's theory, was to assess the relationship between post-materialistic values on one side and religiousness, attitudes towards nationalism, and attitudes towards gender roles on the other among high school students in the city of Split. The research was conducted on a convenience sample of 427 high school students from Split (there were 269 female students and 158 male students with the average age of 17 years. The results indicated that the students from the sample had mixed materialistic and post-materialistic values. Statistically significant differences were found between male and female students in all measured variables. For this reason, analyses were conducted separately by gender. Using multiple regression analysis, it was established that the model with post-materialistic values as the outcome was statistically significant regardless of gender. Discriminative analysis additionally showed that the measured attitudes discriminated groups of students with different levels of post-materialistic values (most prominently, attitudes towards gender roles and religiousness among female students, and attitudes towards nationalism and gender roles among male students. The main finding of the study was that of a difference between male and female students in terms of measured religiousness and two sets of attitudes, as well as gender differences in the relationship between the measured religiousness and the measured attitudes on one side and post-materialistic values on the other. Higher post-materialistic values were associated with lower religiousness among female students and lower acceptance of nationalism among male students.

This study examined the influence of feminist attitudes on self-objectification, habitual body monitoring, and body dissatisfaction in middle age and older women. The participants were 138 European American heterosexual women ranging in age from 40 to 87 years old. Consistent with previous research, self-objectification and habitual body monitoring were positively correlated with body dissatisfaction and, self-objectification and habitual body monitoring remained stable across the lifespan. While age did not moderate the relationship between self-objectification and body dissatisfaction, age was found to moderate the relationship between habitual body monitoring and body dissatisfaction such that the relationship was smaller for older women than for middle-aged women. Interestingly, feminist attitudes were not significantly correlated with body dissatisfaction, self-objectification, or habitual body monitoring, and endorsement of feminist attitudes was not found to moderate the relationship between self-objectification or habitual body monitoring and body dissatisfaction. Potential implications for older women are discussed.

Rohwer, Sievert; Langston, Nancy; Gori, Dave

1996-10-01

We experimentally manipulated the strength of selection in the field on red-winged blackbirds (Agelaius phoeniceus) to test hypotheses about contrasting selective forces that favor either large or small males in sexually size dimorphic birds. Selander (1972) argued that sexual selection favors larger males, while survival selection eventually stabilizes male size because larger males do not survive as well as smaller males during harsh winters. Searcy (1979a) proposed instead that sexual selection may be self limiting: male size might be stabilized not by overwinter mortality, but by breeding-season sexual selection that favors smaller males. Under conditions of energetic stress, smaller males should be able to display more and thus achieve higher reproductive success. Using feeders that provisioned males or females but not both, we produced conditions that mimicked the extremes of natural conditions. We found experimental support for the hypothesis that when food is abundant, sexual selection favors larger males. But even under conditions of severe energetic stress, smaller males did not gain larger harems, as the self-limiting hypothesis predicted. Larger males were more energetically stressed than smaller males, but in ways that affected their future reproductive output rather than their current reproductive performance. Stressed males that returned had smaller wings and tails than those that did not return; among returning stressed males, relative harem sizes were inversely related to wing and tail length. Thus, male body size may be stabilized not by survival costs during the non-breeding season, nor by energetic costs during the breeding season, but by costs of future reproduction that larger males pay for their increased breeding-season effort. © 1996 The Society for the Study of Evolution.

It is known that behavioral disorders and altered food intake are linked to ballet dancers. Thus, the aim of the present study was to investigate the body composition, dietetic profile, self-perceived body image and social desirability in professional ballet dancers. This study was conducted from April to October 2010 in athletes screened for nutritional evaluation. Anthropometric, dietary, social desirability and self-perceived body image evaluation were performed to attend the aim of study. We found that ballet dancers are highly trained and eutrophic, although female dancers had higher adiposity and fat intake than male dancers. In addition, it was observed low consumption of calcium, dietary fiber, potassium, magnesium and vitamin A. Moreover, 30% of male ballet dancers have a strong desire for social acceptance. When the body image was evaluated by Body Shape Questionnaire (BSQ), was reported that 40% of the ballet female dancers have of moderate to severe alteration in body image and 20% of male dancers had slight alteration. Furthermore, the Drawings and Silhouettes Scale showed that 80% of male dancers wish to have a smaller or larger silhouette than the current self-perceived and 60% of the female dancers would like to have a silhouette lower than the self-perceive as current. Collectively, our results shown that most of the dancers were eutrophic, but female athletes have higher adiposity and present strong desire for a different shape of current. Furthermore, was found increased fat intake in female group; however, deficiencies in consumption of dietary fiber, calcium, potassium, magnesium and vitamin A were found in both gender.

Studies show a high cumulative prevalence of musculoskeletal disorders among musicians. Increased emphasis is needed on studying the effectiveness of education and prevention courses in music schools. To investigate the effects on music students of an education and prevention course on body awareness and their attitude toward health and prevention. 23 music students participated in this prospective descriptive comparative study, with 13 students taking the course and serving as a prevention education group (PG) and 10 students serving as a comparison group (CG). The course met once weekly for 2 semesters and included lectures and practical sessions. Before and after the course, participants answered a questionnaire about their level of physical activity, warm-up exercises prior to musical performance, health-promoting activities, and subjective body awareness during musical performance and during activities of daily living (ADL). Over the 9-month study period, the PG group increased, and the CG lessened, the amount of warm-up prior to music performance, showing a significant group difference after the course (p=0.036). Significant interactions were seen for subjective body awareness scores (between groups over time) during practice (p=0.026) and during ADLs (p=0.004), as the PG group had greater positive change over time. No group differences were found in students' subjective rating of body awareness during live performance. Participation in a prevention and education course may be beneficial for music students due to improved subjective body awareness and attitude toward prevention strategies.

Gender development has long term implications for education and career endeavors and family formation behaviors, but we know very little about the role of sociocultural factors in developmental and individual differences. In this study, we investigated one domain of gender development, gender role attitudes, in Mexican-American adolescents (N = 246; 51 % female), using four phases of longitudinal data across 8 years. Data were collected when adolescents averaged 12.51 years (SD = 0.58), 14.64 years (SD = 0.59), 17.72 years (SD = 0.57), and 19.60 years of age (SD = 0.66). Mothers' and fathers' gender role attitudes also were assessed in Phases 1, 3, and 4. Findings revealed that gender attitude development varied as a function of the interaction between adolescents' nativity and gender. Among Mexico-born adolescents, females exhibited significant declines in traditional attitudes from early to late adolescence, but males' attitudes were stable over time. U.S.-born females and males, in contrast, did not differ in their gender attitude trajectories. Examining the links between mothers', fathers', and adolescents' gender role attitudes revealed within-person associations between mothers' and adolescents' gender role attitudes: on occasions when mothers reported more traditional attitudes relative to their own cross-time average, adolescents also reported more traditional attitudes than usual. In addition, fathers' more traditional gender role attitudes were associated with daughters', but not sons', more traditional gender role attitudes at the between-person level. The discussion focuses on the interpretation of Mexican-American adolescents' gender role attitude development from a cultural ecological perspective.

Thirty-six adults (24 males, 12 females) were assessed for anthropometric somatotype and body image (perception and satisfaction) by a novel technique using quantitative distortion of a digital still image. Software produced random distortions in nine body regions. The participants manipulated interactive slider controls to adjust each body feature in turn, recreate their perceived image and indicate their desired image. There were no differences in perception between the sexes. However, the ideal-actual differences (i.e. satisfaction) indicated that males desired larger and females smaller features, respectively, in the chest and thighs (P sport (strength, endurance, team-sport and controls), differences were found in the perceived image size in the chest and rib regions (P < 0.01 and P < 0.05, respectively). Strength athletes perceived these areas to be smaller and the control group perceived these areas to be larger than the true values. Somatotype analysis indicated that the physique associated with minimal dissatisfaction was 2.0-5.0-3.0 for males and 3.0-2.5-3.0 for females. Cluster analysis, combining anthropometric and satisfaction data, revealed seven distinct subgroups distinguished by particular attributes of physical appearance. We conclude that the method is reliable and that body image includes sex-specific, anthropometric, perceptual and personality-related components.

Phramongkutklao College of Medicine is a military medical school and also a health promotion school. As a result, encouraging these medical students to have good attitude toward exercise is considered an important mission for the college. To study the attitudes of medical students at Phramongkutklao College of Medicine about exercise for health promotion. This survey research was carried out in 382 medical students in Academic Year 2008 using questionnaires including personal information, attitude testing and open-ended questions. Statistical analysis was conducted using descriptive analysis: percentage and mean and comparative analysis: t-test and F-test. The overall attitudes of medical students toward exercise were good. The attitudes of the medical cadets were better than those of the civilian medical students. The attitudes and also knowledge about exercise of the higher-year students were generally better than those of the lower-year ones. The attitudes of healthy medical students were higher than those of unhealthy ones. No significant difference in attitude was found between male and female students and between those with different Body Mass Indexes (BMI) and those with different in exercise duration and frequency. The overall medical students' attitudes toward exercise for health promotion in Phramongkutklao College of Medicine were good. The influencial factors were found to be status of medical students, stage of medical study and health status.

The use of unclaimed bodies for anatomical dissection has been the main method of instruction at our institution. There is however a shortage of cadavers for dissection given the increase in the number of medical schools as well as in the number of students enrolling in these schools. This shortage could be mitigated by having voluntary human body donation programs. This study aimed at assessing the attitudes of medical students and surgical residents towards body donation for anatomy learning. We conducted an online survey involving 72 first-year medical students and 41 surgical residents at University of Nairobi who had completed one year of anatomy dissection. For the medical students, this was their first dissection experience while it was the second exposure for the surgery trainees. Most of the surgical trainees (70.7%) and medical students (68.1%) were opposed to self-body donation. This was mainly due to cultural (37%) and religious (20%) barriers. Surprisingly, of those not willing to donate themselves, 67.9% (82.8% surgical trainees, 59.2% medical students) would recommend the practice to other people. Exposure to repeated dissection does not change the perceptions towards body donation. It is noteworthy that culture and religion rank high as clear barriers amongst this “highly informed” group of potential donors. PMID:27190650

Full Text Available Abstract Background Quinine is a natural molecule commonly used as a flavouring agent in tonic water. Diet supplementation with quinine leads to decreased body weight and food intake in rats. Quinine is an in vitro inhibitor of Trpm5, a cation channel expressed in taste bud cells, the gastrointestinal tract and pancreas. The objective of this work is to determine the effect of diet supplementation with quinine on body weight and body composition in male mice, to investigate its mechanism of action, and whether the effect is mediated through Trpm5. Results Compared with mice consuming AIN, a regular balanced diet, mice consuming AIN diet supplemented with 0.1% quinine gained less weight (2.89 ± 0.30 g vs 5.39 ± 0.50 g and less fat mass (2.22 ± 0.26 g vs 4.33 ± 0.43 g after 13 weeks of diet, and had lower blood glucose and plasma triglycerides. There was no difference in food intake between the mice consuming quinine supplemented diet and those consuming control diet. Trpm5 knockout mice gained less fat mass than wild-type mice. There was a trend for a diet-genotype interaction for body weight and body weight gain, with the effect of quinine less pronounced in the Trpm5 KO than in the WT background. Faecal weight, energy and lipid contents were higher in quinine fed mice compared to regular AIN fed mice and in Trpm5 KO mice compared to wild type mice. Conclusion Quinine contributes to weight control in male C57BL6 mice without affecting food intake. A partial contribution of Trpm5 to quinine dependent body weight control is suggested.

Research suggests that the desire to behave sexually with a partner (dyadic sexual desire) may reflect desire for intimacy whereas solitary sexual desire may reflect pleasure seeking motivations more generally. Because direct reproductive success can only be increased with a sexual partner, we tested whether dyadic sexual desire was a better predictor of women's preferences for lower pitched men's voices (a marker of relatively high reproductive success) than was solitary sexual desire. In Study 1, women (N = 95) with higher dyadic sexual desire scores on the Sexual Desire Inventory-2 preferred masculinized male voices more than did women with lower dyadic sexual desire scores. We did not find a significant relationship between women's vocal masculinity preferences and their solitary sexual desire scores. In Study 2, we tested whether the relationship between voice preferences and dyadic sexual desire scores was related to differences in sociosexual orientation. Women (N = 80) with more positive attitudes towards uncommitted sex had stronger vocal masculinity preferences regardless of whether men's attractiveness was judged for short-term or long-term relationships. Independent of the effect of sociosexual attitudes, dyadic sexual desire positively predicted women's masculinity preferences when assessing men's attractiveness for short-term but not long-term relationships. These effects were independent of women's own relationship status and hormonal contraceptive use. Our results provide further evidence that women's mate preferences may independently reflect individual differences in both sexual desire and openness to short-term relationships, potentially with the ultimate function of maximizing the fitness benefits of women's mate choices.

Full Text Available The persistence of food insecurity, malnutrition, increasing adiposity, and decreasing physical activity, heightens the need to understand relationships between body image satisfaction, eating attitudes, BMI and physical activity levels in South Africa. Females aged 18-23 years were recruited from rural (n = 509 and urban (n = 510 settings. Body image satisfaction was measured using Stunkard's silhouettes, and the 26-item Eating Attitudes questionnaire (EAT-26 was used to evaluate participants' risk of disordered eating. Minutes per week of moderate to vigorous physical activity (MVPA was assessed using the Global Physical Activity Questionnaire (GPAQ. Significant linear correlates were included in a series of regressions run separately for urban and rural participants. Structural equation modeling (SEM was used to test the relationships between variables. Urban females were more likely to be overweight and obese than rural females (p = 0.02, and had a greater desire to be thinner (p = 0.02. In both groups, being overweight or obese was positively associated with a desire to be thinner (p<0.01, and negatively associated with a desire to be fatter (p<0.01. Having a disordered eating attitude was associated with body image dissatisfaction in the urban group (β = 1.27, p<0.01, CI: 0.38; 2.16, but only with a desire to be fatter in the rural group (β = 0.63, p = 0.04, CI: 0.03; 1.23. In the SEM model, body image dissatisfaction was associated with disordered eating (β = 0.63, as well as higher MVPA participation (p<0.01. These factors were directly associated with a decreased risk of disordered eating attitude, and with a decreased desire to be thinner. Findings indicate a shift in both settings towards more Westernised ideals. Physical activity may provide a means to promote a healthy body image, while reducing the risk of disordered eating. Given the high prevalence of overweight and obesity in both rural and urban women, this study provides

We examined two hypotheses regarding the potential association of pornography use with body image-related and eating disorder-related psychopathology among sexual minority males (i.e. non-heterosexual males). Our primary hypothesis was that pornography use would be associated with males' body dissatisfaction, eating disorder symptoms, thoughts about using anabolic steroids and quality of life impairment; our secondary hypothesis was that the type of pornography, namely, professional versus amateur pornography, which contains idealised and non-idealised (i.e. regular) bodies, respectively, would moderate these associations. A sample of 2733 sexual minority males living in Australia and New Zealand completed an online survey that contained measures of pornography use, body dissatisfaction, eating disorder symptoms, thoughts about using anabolic steroids and quality of life. Almost all (98.2%) participants reported pornography use with a median use of 5.33 hours per month. Multivariate analyses revealed that increased pornography use was associated with greater dissatisfaction with muscularity, body fat and height; greater eating disorder symptoms; more frequent thoughts about using anabolic steroids; and lower quality of life. Effect sizes for these associations were uniformly small. Neither relationship status nor genital dissatisfaction was associated with pornography use. The association between pornography use and thoughts about using anabolic steroids was stronger for viewers of professional pornography than viewers of amateur pornography. The findings suggest that the use of pornography is weakly associated with body dissatisfaction and related variables and that the type of pornography (amateur vs professional) viewed may be a moderating factor in some cases. Within the limits of a cross-sectional study design, these findings may have implications for clinicians who treat individuals with eating disorders, body dysmorphic disorder, anabolic-androgenic steroid

Body dysmorphic disorder (BDD) was categorised in DSM-5 within the newly created 'obsessive-compulsive and related disorders' chapter, however this classification remains subject to debate. Confirmatory factor analysis was used to test competing models of the co-occurrence of symptoms of BDD, obsessive-compulsive disorder, unipolar depression, anxiety, and eating disorders in a community sample of adolescents, and to explore potential sex differences in these models. Self-report questionnaires assessing disorder symptoms were completed by 3149 Australian adolescents. The fit of correlated factor models was calculated separately in males and females, and measurement invariance testing compared parameters of the best-fitting model between males and females. All theoretical models of the classification of BDD had poor fit to the data. Good fit was found for a novel model where BDD symptoms formed a distinct latent factor, correlated with affective disorder and eating disorder latent factors. Metric non-invariance was found between males and females, and the majority of factor loadings differed between males and females. Correlations between some latent factors also differed by sex. Only cross-sectional data were collected, and the study did not assess a broad range of DSM-5 defined eating disorder symptoms or other disorders in the DSM-5 obsessive-compulsive and related disorders chapter. This study is the first to statistically evaluate competing models of BDD classification. The findings highlight the unique features of BDD and its associations with affective and eating disorders. Future studies examining the classification of BDD should consider developmental and sex differences in their models. Copyright © 2017. Published by Elsevier B.V.

2017-01-01

Objective . To explore, in female and male patients with medically treated, moderately advanced Parkinson's disease (PD), their knowledge and reasoning about Deep Brain Stimulation (DBS). Methods . 23 patients with PD (10 women), aged 46-70, were interviewed at a mean of 8 years after diagnosis, with open-ended questions concerning their reflections and considerations about DBS. The interviews were transcribed verbatim and analysed according to the difference and similarity technique in Grounded Theory. Results . From the patients' narratives, the core category "Processing DBS: balancing symptoms, fears and hopes" was established. The patients were knowledgeable about DBS and expressed cautious and well considered attitudes towards its outcome but did not consider themselves ill enough to undergo DBS. They were aware of its potential side-effects. They considered DBS as the last option when oral medication is no longer sufficient. There was no difference between men and women in their reasoning and attitudes towards DBS. Conclusion . This study suggests that knowledge about the pros and cons of DBS exists among PD patients and that they have a cautious attitude towards DBS. Our patients did not seem to endorse an earlier implementation of DBS, and they considered that it should be the last resort when really needed.

The mating brain: early maturing sneaker males maintain investment into the brain also under fast body growth in Atlantic salmon (Salmo salar).

It has been suggested that mating behaviours require high levels of cognitive ability. However, since investment into mating and the brain both are costly features, their relationship is likely characterized by energetic trade-offs. Empirical data on the subject remains equivocal. We investigated if early sexual maturation was associated with brain development in Atlantic salmon ( Salmo salar ), in which males can either stay in the river and sexually mature at a small size (sneaker males) or migrate to the sea and delay sexual maturation until they have grown much larger (anadromous males). Specifically, we tested how sexual maturation may induce plastic changes in brain development by rearing juveniles on either natural or ad libitum feeding levels. After their first season we compared brain size and brain region volumes across both types of male mating tactics and females. Body growth increased greatly across both male mating tactics and females during ad libitum feeding as compared to natural feeding levels. However, despite similar relative increases in body size, early maturing sneaker males maintained larger relative brain size during ad libitum feeding levels as compared to anadromous males and females. We also detected several differences in the relative size of separate brain regions across feeding treatments, sexes and mating strategies. For instance, the relative size of the cognitive centre of the brain, the telencephalon, was largest in sneaker males. Our data support that a large relative brain size is maintained in individuals that start reproduction early also during fast body growth. We propose that the cognitive demands during complex mating behaviours maintain a high level of investment into brain development in reproducing individuals.

The relationship between media exposure and antifat attitudes: the role of dysfunctional appearance beliefs.

2009-01-01

This study examined the relationship between media exposure, antifat attitudes, and body dissatisfaction, as well as the mediating effect of dysfunctional appearance beliefs. A sample of 112 women completed surveys measuring media exposure, antifat attitudes, body dissatisfaction, and dysfunctional beliefs about appearance. It was found that time spent reading fashion magazines was positively correlated with antifat attitudes and that this relationship was mediated by dysfunctional beliefs about appearance. Measures of antifat attitudes and body dissatisfaction were both found to be correlated with endorsement of dysfunctional beliefs about appearance and body mass index. Results suggest that time spent reading fashion magazines may be related to antifat attitudes through dysfunctional appearance beliefs.

The main aim of this study was to compare the thermal responses and the responses of cognitive and motor functions to intermittent cold stress between males and females. The intermittent cold stress continued until rectal temperature (TRE) reached 35.5°C or for a maximum of 170 min. Thermal response and motor and cognitive performance were monitored. During intermittent cold stress, body temperature variables decreased in all subjects (P cold strain index did not differ between sexes. Maximal voluntary contraction (MVC) decreased after intermittent cold exposure only in males (P cold stress on electrically evoked muscle properties, spinal (H-reflex), and supraspinal (V-waves) reflexes did not differ between sexes. Intermittent cold-induced cognitive perturbation of attention and memory task performance was greater in males (P whole-body cold immersion. Although no sex-specific differences were observed in muscle EMG activity, involuntary muscle properties, spinal and supraspinal reflexes, some of the sex differences observed (e.g., lower isometric MVC and greater cognitive perturbation in males) support the view of sex-specific physiological responses to core temperature decrease.

Full Text Available Haiti has the highest number of people living with HIV infection in the Caribbean/Latin America region. Medical male circumcision (MMC has been recommended to help prevent the spread of HIV. We sought to assess knowledge, attitudes, practices and beliefs about MMC among a sample of health care providers in Haiti.A convenience sample of 153 health care providers at the GHESKIO Centers in Haiti responded to an exploratory survey that collected information on several topics relevant to health providers about MMC. Descriptive statistics were calculated for the responses and multivariable logistic regression was conducted to determine opinions of health care providers about the best age to perform MMC on males. Bayesian network analysis and sensitivity analysis were done to identify the minimum level of change required to increase the acceptability of performing MMC at age less than 1 year.The sample consisted of medical doctors (31.0%, nurses (49.0%, and other health care professionals (20.0%. Approximately 76% showed willingness to offer MMC services if they received training. Seventy-six percent believed that their male patients would accept circumcision, and 59% believed infancy was the best age for MMC. More than 90% of participants said that MMC would reduce STIs. Physicians and nurses who were willing to offer MMC if provided with adequate training were 2.5 (1.15-5.71 times as likely to choose the best age to perform MMC as less than one year. Finally, if the joint probability of choosing "the best age to perform MMC" as one year or older and having the mistaken belief that "MMC prevents HIV entirely" is reduced by 63% then the probability of finding that performing MMC at less than one year acceptable to health care providers is increased by 35%.Participants demonstrated high levels of knowledge and positive attitudes towards MMC. Although this study suggests that circumcision is acceptable among certain health providers in Haiti, studies

The aim of this cross-sectional study was to investigate relationships among women's body attitudes, physical symptoms, self-esteem, depression, and sleep quality during pregnancy. Pregnant women (N=215) at 15-25 weeks gestation completed a questionnaire including four body image subscales assessing self-reported feeling fat, attractiveness, strength/fitness, and salience of weight and shape. Women reported on 29 pregnancy-related physical complaints, and completed the Beck Depression Inventory, Rosenberg Self-esteem Scale, and Pittsburgh Sleep Quality Index. In regressions, controlling for retrospective reports of body image, more frequent and intense physical symptoms were related to viewing the self as less strong/fit, and to poorer sleep quality and more depressive symptoms. In a multi-factorial model extending previous research, paths were found from sleep quality to depressive symptoms to self-esteem; self-esteem was found to be a mediator associated with lower scores on feeling fat and salience of weight and shape, and on higher perceived attractiveness.

Exploration of Dating Violence and Related Attitudes Among Adolescents and Emerging Adults.

Courtain, Audrey; Glowacz, Fabienne

Young people's romantic relationships can be marked with various forms of dating violence (DV). However, adolescents and emerging adults do not necessarily acknowledge this violence because of their attitudes toward dating violence. Our study aims to study dating violence and attitudes toward this phenomenon through two well-established questionnaires administered jointly in their entirety. Indeed, too many studies report results on some dimensions and items, neglecting the richness of available tools. The Conflict in Adolescent Dating Relationship Inventory and the Attitudes Toward Dating Violence Scale were self-administered to 1,014 participants ( M age = 18.9) attending secondary schools or a regional college. They reported the frequency of their dating violence perpetration and victimization, and their attitudes toward dating violence. Results show that relational and sexual violence perpetration rates are higher for males, physical violence perpetration rate is higher for females, and relational violence victimization is higher for males. MANCOVAs not only show the same trends for scores but also underline more frequent emotional violence perpetrated by females, physical victimization for males, and sexual victimization for females. Males show higher tolerance toward every form of dating violence; younger participants are also more tolerant. Participants are more tolerant toward male-perpetrated psychological DV than female-perpetrated ones, and more tolerant toward female-perpetrated physical and sexual DV compared with male-perpetrated physical and sexual DV. There are patterns of multiperpetration, multivictimization, bidirectionality, and multi(in)tolerance. Our paper contributes to the symmetry debate, a better understanding of the link between attitudes and violent behaviors, a further step on gendered attitudes regarding who perpetrates and who sustains.

Non-adherence was more frequent in male than in female psychiatric patients. This multi-center study in China examined the gender difference with regard to attitude towards antipsychotic medications and its associations with socio-demographic variables, insight, and psychopathology. Patients' basic socio-demographic and clinical data were collected. Psychopathology and insight were measured with the Symptom Checklist-90 (SCL-90) and the Insight and Treatment Attitudes Questionnaire (ITAQ), respectively. Their attitudes towards antipsychotic medications were assessed by two standardized questions. Nearly 39.6% (109/275) males and 31.1% (70/225) females reported negative attitudes towards antipsychotic medications. Binary logistic regression revealed that in males single marital status (OR=2.9, 95% CI=1.3-6.4), rural residence (OR=0.4, 95% CI=0.2-0.7), longer duration of schizophrenia (OR=1.0, 95% CI=1.0-1.1), knowledge of medication (OR=1.5, 95% CI=1.3-1.6) and the SCL-90 hostility subscale (OR=0.9, 95% CI=0.9-1.0) were contributors to negative attitudes. In female patients, knowledge about medications (OR=1.4, 95% CI=1.3-1.6), the SCL-90 somatization (OR=0.8, 95% CI=0.8-0.9) and anxiety (OR=1.1, 95% CI=1.0-1.2) subscales were contributors to negative attitudes. The study suggested that different psychosocial and clinical factors accounted for the negative attitude towards antipsychotic treatment in male and female patients.

In free-living animals, recent evidence indicates that innate, and acquired, immunity varies with annual variation in the demand for, and availability of, food resources. However, little is known about how animals adjust the relationships between immunity and body condition, and between innate and acquired immunity to optimize survival over winter and reproductive success during the breeding stage. Here, we measured indices of body condition (size-corrected mass [SCM], and hematocrit [Hct]), constitutive innate immunity (plasma total complement hemolysis activity [CH 50 ]) and acquired immunity (plasma immunoglobulin A [IgA]), plus heterophil/lymphocyte (H/L) ratios, in male Eurasian tree sparrows (Passer montanus) during the wintering and the breeding stages. We found that birds during the wintering stage had higher IgA levels than those from the breeding stage. Two indices of body condition were both negatively correlated with plasma CH 50 activities, and positively with IgA levels in wintering birds, but this was not the case in the breeding birds. However, there was no correlation between CH 50 activities and IgA levels in both stages. These results suggest that the relationships between body condition and immunity can vary across life-history stage, and there are no correlations between innate and acquired immunity independent of life-history stage, in male Eurasian tree sparrows. Therefore, body condition indices predict immunological state, especially during the non-breeding stage, which can be useful indicators of individual immunocompetences for understanding the variations in innate and acquired immunity in free-living animals.

Exclusive paternal care is the rarest form of parental investment in nature and theory predicts that the maintenance of this behavior depends on the balance between costs and benefits to males. Our goal was to assess costs of paternal care in the harvestman Iporangaia pustulosa, for which the benefits of this behavior in terms of egg survival have already been demonstrated. We evaluated energetic costs and mortality risks associated to paternal egg-guarding in the field. We quantified foraging activity of males and estimated how their body condition is influenced by the duration of the caring period. Additionally, we conducted a one-year capture-mark-recapture study and estimated apparent survival probabilities of caring and non-caring males to assess potential survival costs of paternal care. Our results indicate that caring males forage less frequently than non-caring individuals (males and females) and that their body condition deteriorates over the course of the caring period. Thus, males willing to guard eggs may provide to females a fitness-enhancing gift of cost-free care of their offspring. Caring males, however, did not show lower survival probabilities when compared to both non-caring males and females. Reduction in mortality risks as a result of remaining stationary, combined with the benefits of improving egg survival, may have played an important and previously unsuspected role favoring the evolution of paternal care. Moreover, males exhibiting paternal care could also provide an honest signal of their quality as offspring defenders, and thus female preference for caring males could be responsible for maintaining the trait.

Commonly used dating violence prevention programs assume that promotion of more egalitarian gender role attitudes will prevent dating violence perpetration. Empirical research examining this assumption, however, is limited and inconsistent. The current study examined the longitudinal association between gender role attitudes and physical dating violence perpetration among adolescent boys (n = 577; 14 % Black, 5 % other race/ethnicity) and examined whether injunctive (i.e., acceptance of dating violence) and descriptive (i.e., beliefs about dating violence prevalence) normative beliefs moderated the association. As expected, the findings suggest that traditional gender role attitudes at T1 were associated with increased risk for dating violence perpetration 18 months later (T2) among boys who reported high, but not low, acceptance of dating violence (injunctive normative beliefs) at T1. Descriptive norms did not moderate the effect of gender role attitudes on dating violence perpetration. The results suggest that injunctive norms and gender role attitudes work synergistically to increase risk for dating violence perpetration among boys; as such, simultaneously targeting both of these constructs may be an effective prevention approach.

2016-01-01

The present study examined Chinese university students' attitudes toward same-sex attraction and behavior, the socio-demographic correlates of these attitudes, and the potential gender differences in both tendencies and correlates. A total of 2,644 Chinese university students (49.7% male, mean age = 20.27 years) indicated generally negative attitudes toward same-sex attraction and behavior, with males reporting more negative attitudes than females. More years in university (i.e., higher grade levels), higher levels of maternal education, growing up in an urban area, and more frequent Internet use significantly predicted more positive attitudes. Gender significantly moderated one correlate: For female participants, a higher university grade was related to more positive attitudes; this correlation was not significant for male participants. The findings suggest valuable directions for related intervention practices for young people in China.

The aim of this study was to explore the differences in patterns of risk factors for body dissatisfaction and disordered eating attitudes in both female and male adolescents from Portugal and Spain. The sample included 455 adolescents aged 12-16 years (M = 13.28, SD = 0.65) from two urban areas of each country. Body mass index, self-reported self-esteem, perfectionism, internalisation of sociocultural ideals, body dissatisfaction and disordered eating attitudes were assessed. Path analyses provided partial support for a cross-cultural model of body dissatisfaction and disordered eating in Western countries due to the presence of certain differences in the patterns of relationships across sex and country. The findings suggest the importance not only of identifying cultural specificities, even in "neighbouring" countries, but also of developing a global and comprehensive preventive approach that focuses on the influence of the ideal of beauty transmitted by Western societies.

Objective. To explore, in female and male patients with medically treated, moderately advanced Parkinson's disease (PD), their knowledge and reasoning about Deep Brain Stimulation (DBS). Methods. 23 patients with PD (10 women), aged 46–70, were interviewed at a mean of 8 years after diagnosis, with open-ended questions concerning their reflections and considerations about DBS. The interviews were transcribed verbatim and analysed according to the difference and similarity technique in Grounded Theory. Results. From the patients' narratives, the core category “Processing DBS: balancing symptoms, fears and hopes” was established. The patients were knowledgeable about DBS and expressed cautious and well considered attitudes towards its outcome but did not consider themselves ill enough to undergo DBS. They were aware of its potential side-effects. They considered DBS as the last option when oral medication is no longer sufficient. There was no difference between men and women in their reasoning and attitudes towards DBS. Conclusion. This study suggests that knowledge about the pros and cons of DBS exists among PD patients and that they have a cautious attitude towards DBS. Our patients did not seem to endorse an earlier implementation of DBS, and they considered that it should be the last resort when really needed. PMID:28458943

Risk attitudes play important roles in health behavior and everyday decision making. It is unclear, however, whether these attitudes can be predicted from birth order. We investigated 200 mostly male volunteers from two distinct settings. After correcting for multiple comparisons, for the number of siblings and for confounding by gender, ordinal position predicted perception of health-related risks among participants in extreme sports (p < .01).

Falomir-Pichastor, Juan Manuel; Martínez, Carmen; Paterna, Consuelo

2010-11-01

Two hundred and twenty-six heterosexual participants (115 women and 111 men) were asked to indicate their attitude toward gender-roles, their perceived similarities with gay men, and their attitude toward gay men (i.e., sexual prejudice). As expected, male participants showed more sexual prejudice than female participants, and perceived dissimilarities were related to a greater sexual prejudice. Support for gender-roles was related to sexual prejudice for male participants, but not for female participants. More interestingly, the three-way interaction suggested that perceived similarities moderated the link between gender-roles and sexual prejudice among heterosexual men, but not among heterosexual women. Attitude in favor of traditional gender-roles was related to sexual prejudice for male participants who perceived gay men as different, but not for those who perceived gay men as similar. These findings are discussed in terms of the defensive function of men's attitude toward homosexuality as a result of threat to masculinity.

Diabetes type 2 is a world wide spread disease with a multifactorial pathogenetic evolution. Various factors like obesity, physical inactivity and poor lifestyle habits contribute to its development. The aim of this study was to verify if in young healthy sedentary male and female there is positive correlation between family history to type 2 diabetes and an increase in body weight and fat mass, or alterations in basal glycemia values. Totally183 male and 237 female healthy sedentary subjects were analysed in 2012, in Italy. They were divided in three groups: FH(+) with first degree family history, FH(++) with second degree family history and FH(-) with no family history. Anthropometrics, body composition and blood parameters were assessed. Male had the highest BMI values (Plife-style changes, such as increased physical activity and controlled quantity and quality of food intake.

The effect of boron supplementation was investigated in 19 male bodybuilders ages 20-27 years. Ten were given a 2.5-mg boron supplement while 9 were given a placebo every day for 7 weeks. Plasma total and free testosterone, plasma boron, lean body mass, and strength measurements were determined on Days 1 and 49 of the study. Plasma boron values were significantly (p bodybuilding can increase total testosterone, lean body mass, and strength in lesser trained bodybuilders, and that boron supplementation had no effect on these measures.

The Body and the Beautiful: Health, Attractiveness and Body Composition in Men's and Women's Bodies.

Directory of Open Access Journals (Sweden)

Mary-Ellen Brierley

Full Text Available The dominant evolutionary theory of physical attraction posits that attractiveness reflects physiological health, and attraction is a mechanism for identifying a healthy mate. Previous studies have found that perceptions of the healthiest body mass index (weight scaled for height; BMI for women are close to healthy BMI guidelines, while the most attractive BMI is significantly lower, possibly pointing to an influence of sociocultural factors in determining attractive BMI. However, less is known about ideal body size for men. Further, research has not addressed the role of body fat and muscle, which have distinct relationships with health and are conflated in BMI, in determining perceived health and attractiveness. Here, we hypothesised that, if attractiveness reflects physiological health, the most attractive and healthy appearing body composition should be in line with physiologically healthy body composition. Thirty female and 33 male observers were instructed to manipulate 15 female and 15 male body images in terms of their fat and muscle to optimise perceived health and, separately, attractiveness. Observers were unaware that they were manipulating the muscle and fat content of bodies. The most attractive apparent fat mass for female bodies was significantly lower than the healthiest appearing fat mass (and was lower than the physiologically healthy range, with no significant difference for muscle mass. The optimal fat and muscle mass for men's bodies was in line with the healthy range. Male observers preferred a significantly lower overall male body mass than did female observers. While the body fat and muscle associated with healthy and attractive appearance is broadly in line with physiologically healthy values, deviations from this pattern suggest that future research should examine a possible role for internalization of body ideals in influencing perceptions of attractive body composition, particularly in women.

Lunde, Carolina

2013-09-01

This study examined adolescents' attitudes of cosmetic surgery, as well as the relationships between these attitudes, body appreciation, body ideal internalization, and fashion blog reading. The sample comprised 110 (60 boys, 50 girls) late adolescents (mean age 16.9 years) from a Swedish high school. The results indicated that younger adolescents seem somewhat more accepting of cosmetic surgery. This was especially the case for boys' acceptance of social motives for obtaining cosmetic surgery (boys' M=2.3±1.55 vs. girls' M=1.7±0.89). Girls', and to a limited extent boys', internalization of the thin ideal was related to more favorable cosmetic surgery attitudes. Athletic ideal internalization and body appreciation were unrelated to these attitudes. Finally, girls who frequently read fashion blogs reported higher thin ideal internalization, and also demonstrated a slight tendency of more cosmetic surgery consideration.

The purpose of conducting this survey was to identify data on consumer attitudes towards and beliefs about physical activity, body weight and health among the 15 countries of the EU. A cross-sectional study to get a picture of the attitudes to physical activity, body weight and health in the EU. For this, it was considered important that samples be nationally representative so that inferences drawn from the data could be applied to the population in each country as well as to the EU population as a whole. Using a non-probability sampling method employing quota controls (and the national weight) we obtained large sample sizes from each country which were nationally representative in terms of the variables age, sex and regional distribution. To ensure samples were truly nationally representative a national weight was used when analysing the data using the same characteristics as those used to define quotas. When examining pooled estimates for the total EU sample a population weight was applied. In total, 15,239 subjects aged 15 years and upwards in the EU completed the survey. This article gives details on the methods used in carrying out the survey from design of the questionnaire to sample selection, questionnaire administration and analysis of the data. The methods and their limitations are discussed.

After correcting for multiple comparisons, for the number of siblings and for confounding by gender, ordinal position predicted perception of health-related risks among participants in extreme sports (p < .01). However, the direction of the effect contradicted Adlerian theory. Except for alcohol consumption, these findings extended to self-reported risk behavior. Together, the data call for a cautious stand on the impact of birth order on risk attitudes. © The Author(s) 2013.

Factors associated with sexual behavior and attitudes of never-married rural Thai youth.

Isarabhakdi, P

1999-07-01

This study examined the factors associated with sexual behavior and attitudes of never-married youth in Thailand. Data obtained from 577 never married males and 517 never married females aged 15-24 years were analyzed. Multivariate analyses using a logistic regression revealed that there was a difference in male-female sexual attitudes and behavior bearing important consequences. More than half of the Thai male adolescents were sexually active and the majority of their sexual encounters appeared to be with commercial sex workers. In contrast, the majority of young sexually active Thai female adolescents engaged in sexual acts with their boyfriends. The results suggested that although family variables had no effect on never-married youths' sexual behaviors, it had an influence in the formation of their attitudes. The factors that were most likely to affect the probability of having premarital sex were related to loosening constraints, especially parental and community control. In terms of cultural norms pertaining to sexuality in Thailand, differences in attitude and behavior between males and females can be explained by the impact of early socialization on the patterns of sexual behavior. Young women in this study expressed more nonpermissive attitudes about premarital sexuality and had much lower rates not only of sexual intercourse but also of all types of sex-related behaviors compared to their male counterparts.

Induction of myeloid leukaemia by whole-body single exposure of CBA male mice to X-rays

Major, I R [Medical Research Council, Harwell (UK). Radiobiological Research Unit

1979-12-01

A curvilinear dose response of myeloid leukaemia induction in CBA male mouse was obtained after single whole-body X-irradiation at about 3 months of age. This strain has a very low spontaneous incidence of the disease and no cases were found in the unirradiated controls. The incidence was independent of dose rate over the range used (4.2-552 rad/min). Diagnosis required histopathological examination of various body tissues, the gross anatomical changes being easily confused with other haemopoietic disorders, but a few cases were recognized in life from blood samples. Curve-fitting to various models based on theories of radiocarcinogenic mechanism is described.

Male density affects large-male advantage in the golden silk spider, Nephila clavipes

OpenAIRE

2010-01-01

Across a variety of animal taxa, the outcome of male--male contests depends on male body size; winners are usually the larger males or the males with bigger weapons. However, high male density can either increase or reverse large-male advantage because density changes the frequency and intensity of male--male interactions. In the golden orb-web spider Nephila clavipes, large males have a competitive advantage in male--male contests. However, this species shows more than 2-fold variation in ma...

Pancreatic polypeptide (PP) is released from the pancreas in response to a meal. In humans, low-circulating PP levels have been observed in obesity, and administration of pharmacological doses of PP has been shown to decrease food intake. The aim of the present study was to investigate whether low...... circulating PP is associated with weight gain in Pima Indians. Plasma PP concentrations were measured after an overnight fast and 30 min after a standardized mixed meal in 33 nondiabetic male subjects who had a follow-up visit 4.9 +/- 2.5 years later. Cross-sectionally, fasting and postprandial PP levels were...... negatively associated with body size and adiposity. Prospectively, the change in PP response to the meal was negatively associated with the change in body weight (r = -0.53, P = 0.002). In contrast, a high fasting PP level was positively associated with change in body weight (r = 0.45, P = 0...

Full Text Available Recent studies in math education focus on differences between behaviors and performances of male and female students. In this study, achievement and attitudes of middle school students to math were described in terms of gender and grade differences. The aim of this study is to determine whether any differences exist between female and male students’ attitudes and successes of middle school toward mathematics. This research was designed as a descriptive research. Students (6th, 7th, and 8th grades were registered to “Attitude Survey toward Mathematics”. This survey is consisted of two parts. In the first part, there are demographic questions. The second part is 5-Likert type survey which is intended to learn students’ attitudes toward mathematics. Secondly, in order to determine students’ achievements from mathematics, their grades and their state exam results were used. Because of the possibility of differentiation in teachers’ evaluation criteria and their objectivity on students’ successes, both students’ scores from state exam and their course grades were included to the analysis.The findings of this research indicate that attitude of the students toward mathematics and achievement scores in Mathematics have a significant difference in terms of their gender and grade levels. Female students performed more positive attitudes than male students toward Mathematics and female students had higher grades than male students.

The SB protocol elevated T (21% and C (50% concentrations with a higher T/C ratio (28% after FB training (all p ≤ 0.039. The strength changes were similar, but the body composition and hormonal results differed by protocol. Slope testing on the individual responses identified positive associations (p ≤ 0.05 between T and C concentrations and absolute 1RM strength in stronger (squat 1RM = 150.5 kg, but not weaker (squat 1RM = 117.4 kg, men. A short window of training involving FB or SB protocols can improve strength and body composition in rugby players. The similar strength gains highlight training volume as a key adaptive stimulus, although the programme structure (i.e. FB or SB did influence the body composition and hormonal outcomes. It also appears that 1RM strength is associated with individual hormonal changes and baseline strength.

Shepherd, R; Towler, G

2007-06-01

Validated questionnaires eliciting information on nutrition knowledge and attitudes, related to fat intake from meat, meat products, dairy products and fried foods, were completed by 538 subjects. There were high correlations (ranging from 0.40 to 0.77) between the sums of belief-evaluations, attitudes, intention and self-reported behaviour, with similar correlations for a subgroup of males aged 35-54 years. Nutrition knowledge, showed some statistically significant (but small) negative correlations with components of attitudes. Females had higher nutrition knowledge scores and more negative views of the foods than did males. Fat intake, measured using 3 day weighed intakes, correlated with self-reported behaviour (r = 0.55, p<0.01) in a subsample of 30 males, aged 35-54 years. Thus, nutrition knowledge seems less clearly related to consumption of these foods than are more specific beliefs and attitudes.

LRGUK-1 is required for basal body and manchette function during spermatogenesis and male fertility.

Directory of Open Access Journals (Sweden)

Yan Liu

2015-03-01

Full Text Available Male infertility affects at least 5% of reproductive age males. The most common pathology is a complex presentation of decreased sperm output and abnormal sperm shape and motility referred to as oligoasthenoteratospermia (OAT. For the majority of OAT men a precise diagnosis cannot be provided. Here we demonstrate that leucine-rich repeats and guanylate kinase-domain containing isoform 1 (LRGUK-1 is required for multiple aspects of sperm assembly, including acrosome attachment, sperm head shaping and the initiation of the axoneme growth to form the core of the sperm tail. Specifically, LRGUK-1 is required for basal body attachment to the plasma membrane, the appropriate formation of the sub-distal appendages, the extension of axoneme microtubules and for microtubule movement and organisation within the manchette. Manchette dysfunction leads to abnormal sperm head shaping. Several of these functions may be achieved in association with the LRGUK-1 binding partner HOOK2. Collectively, these data establish LRGUK-1 as a major determinant of microtubule structure within the male germ line.

GI Joe or Average Joe? The impact of average-size and muscular male fashion models on men's and women's body image and advertisement effectiveness.

Diedrichs, Phillippa C; Lee, Christina

2010-06-01

Increasing body size and shape diversity in media imagery may promote positive body image. While research has largely focused on female models and women's body image, men may also be affected by unrealistic images. We examined the impact of average-size and muscular male fashion models on men's and women's body image and perceived advertisement effectiveness. A sample of 330 men and 289 women viewed one of four advertisement conditions: no models, muscular, average-slim or average-large models. Men and women rated average-size models as equally effective in advertisements as muscular models. For men, exposure to average-size models was associated with more positive body image in comparison to viewing no models, but no difference was found in comparison to muscular models. Similar results were found for women. Internalisation of beauty ideals did not moderate these effects. These findings suggest that average-size male models can promote positive body image and appeal to consumers. 2010 Elsevier Ltd. All rights reserved.

Science Anxiety, Science Attitudes, and Constructivism: A Binational Study

Bryant, Fred B.; Kastrup, Helge; Udo, Maria; Hislop, Nelda; Shefner, Rachel; Mallow, Jeffry

2013-08-01

Students' attitudes and anxieties about science were measured by responses to two self-report questionnaires. The cohorts were Danish and American students at the upper secondary- and university-levels. Relationships between and among science attitudes, science anxiety, gender, and nationality were examined. Particular attention was paid to constructivist attitudes about science. These fell into at least three broad conceptual categories: Negativity of Science Toward the Individual, Subjective Construction of Knowledge, and Inherent Bias Against Women. Multigroup confirmatory factor analyses revealed that these dimensions of constructivist attitudes were equally applicable and had the same meaning in both cultures. Gender differences in mean levels of constructivist attitudes were found; these varied across the two cultures. Constructivist beliefs were associated with science anxiety, but in different ways for females and males, and for Danes and Americans. In agreement with earlier studies, females in both the US and Danish cohorts were significantly more science anxious than males, and the gender differences for the Americans were larger than those for the Danes. Findings are discussed in terms of their implications for reducing science anxiety by changing constructivist beliefs.

Full Text Available The present study examined Chinese university students’ attitudes toward same-sex attraction and behavior, the socio-demographic correlates of these attitudes, and the potential gender differences in both tendencies and correlates. A total of 2,644 Chinese university students (49.7% male, mean age = 20.27 years indicated generally negative attitudes toward same-sex attraction and behavior, with males reporting more negative attitudes than females. More years in university (i.e., higher grade levels, higher levels of maternal education, growing up in an urban area, and more frequent Internet use significantly predicted more positive attitudes. Gender significantly moderated one correlate: For female participants, a higher university grade was related to more positive attitudes; this correlation was not significant for male participants. The findings suggest valuable directions for related intervention practices for young people in China. Key words: Chinese university students, same-sex attraction and behavior, gender differences

Full Text Available This study aimed to investigate associations among body dissatisfaction, behaviors, feelings, and beliefs related to the body - and somatotypical profile. The sample included 142 undergraduate female students (21.81 ± 3 years who underwent to assessment of Body Mass Index and somatotype, according to the World Health Organization and Heath-Carter protocols, respectively. To assess body image the following instruments were applied: Body Shape Questionnaire, Body Attitudes Questionnaire, Body Image Avoidance Questionnaire, Sociocultural Attitudes Towards Appearance Scale, Self-Subject Silhouettes To the analysis data we proceeded to multivariate analysis of variance (MANOVA one-way. As the main result, we find that body dissatisfaction, body avoidance and negative attitudes about appearance components are linked to each other and they are influenced by body profiles with mesomorphic and endomorphic predominance. We conclude that the somatotype profile can be an important predictor of changes in body image and is indicated for tracking risk groups.

From the patients’ narratives, the core category “Processing DBS: balancing symptoms, fears and hopes” was established. The patients were knowledgeable about DBS and expressed cautious and well considered attitudes towards its outcome but did not consider themselves ill enough to undergo DBS. They were aware of its potential side-effects. They considered DBS as the last option when oral medication is no longer sufficient. There was no difference between men and women in their reasoning and attitudes towards DBS. Conclusion. This study suggests that knowledge about the pros and cons of DBS exists among PD patients and that they have a cautious attitude towards DBS. Our patients did not seem to endorse an earlier implementation of DBS, and they considered that it should be the last resort when really needed.

Research has shown that negative attitudes toward lesbians and gay men are common and widespread in Western societies. However, few studies have addressed attitudes toward transgender individuals. In addition, although research has shown that homophobic harassment and bullying is highly common among adolescents, little is known about adolescent's attitudes toward sexual minorities. This study aimed to fill these gaps in knowledge, by investigating adolescents' attitudes toward transgender individuals and possible attitudinal correlates of those attitudes. Participants (N = 188; 62 males and 126 females) were recruited in high schools in Lisbon, Portugal. Age ranged from 15 to 19 years (M = 17; SD = .96). Participants completed a questionnaire booklet measuring attitudes toward transgender individuals, lesbians, and gay men, and gender role beliefs. Results revealed that attitudes toward transgender individuals were significantly correlated with all attitude measures. Specifically, it was revealed that those participants who endorsed negative attitudes toward transgender individuals were also endorsing of negative attitudes toward lesbians and gay men and tended to adhere to traditional gender roles. A significant gender effect was found with males being more negative toward sexual minorities than females, but these negative attitudes were more extreme toward gay men than toward lesbian women. Implications of these findings are discussed.

Obesity contributes to increased risk for several chronic diseases including cardiovascular disease and type 2 diabetes. Xanthohumol, a prenylated flavonoid from hops (Humulus lupulus), was tested for efficacy on biomarkers of metabolic syndrome in 4 week old Zucker fa/fa rats, a rodent model of obesity. Rats received daily oral doses of xanthohumol at 0, 1.86, 5.64, and 16.9 mg/kg BW for 6 weeks. All rats were maintained on a high fat (60% kcal) AIN-93G diet for 3 weeks to induce severe obesity followed by a normal AIN-93G (15% kcal fat) diet for the last 3 weeks of the study. Weekly food intake and body weight were recorded. Plasma cholesterol, glucose, insulin, triglyceride, and monocyte chemoattractant protein-1 (MCP-1) levels were assessed using commercial assay kits. Plasma and liver tissue levels of XN and its metabolites were determined by liquid-chromatography tandem mass spectrometry. Plasma and liver tissue levels of xanthohumol were similar between low and medium dose groups and significantly (peffect on body weight and plasma glucose levels. The highest dose group (n=6) had significantly lower plasma glucose levels compared to the control group (n=6) in male but not female rats. There was also a significant decrease in body weight for male rats in the highest dose group (16.9 mg/kg BW) compared to rats that received no xanthohumol, which was also not seen for female rats. Plasma cholesterol, insulin, triglycerides, and MCP-1 as well as food intake were not affected by treatment. The findings suggest that xanthohumol has beneficial effects on markers of metabolic syndrome. Copyright © 2012. Published by Elsevier Ltd.

In this study, we conducted a content analysis of 243 photographic images of men published on the gay male-oriented blog Queerty.com. We also analyzed 435 user-generated comments from a randomly selected 1-year sample. Focusing on images' body types, we found that the range of body types featured on the blog was quite narrow-the vast majority of images had very low levels of body fat and very high levels of muscularity. Users' body image-related comments typically endorsed and celebrated images; critiques of images were comparatively rare. Perspectives from objectification theory and social comparison theory suggest that the images and commentary found on the blog likely reinforce unhealthy body image in gay male communities.

Factors affecting aggressive behaviour of spawning migratory males towards mature male parr in masu salmon Oncorhynchus masou.

Watanabe, M; Maekawa, K

2010-07-01

This study examined whether dominant migratory males (adopting fighter tactics) of the masu salmon Oncorhynchus masou would more aggressively attack large mature male parr (adopting sneaker tactics) as large mature male parr are expected to have the potential to cause a greater decrease in fertilization success. The frequency of aggressive behaviour was not related to the body size of males, and it increased with the frequency of interactions with mature male parr. The fertilization success of mature male parr was much lower than migratory males, and no relationship was observed between fertilization success and aggressive behaviour. The low fertilization success of mature male parr, despite infrequent aggressive behaviour by migratory males, indicates that there might be little benefit for migratory males to attack mature male parr more aggressively according to their body size.

Methods & Materials: In this semi-experimental study, twenty two eligible males from the members of an elderly daycare center with more than 60 years of age were enrolled and were divided into three groups randomly, WBVT+Cr(n=7, WBVT+Pgroup (n=7, and control group (n=8. In WBVT+Cr and WBVT+P groups exercises were performed on the whole body vibration device for 10 days with 30-35 Hz intensity and 5 mm amplitude. The WBVT+Cr group consumed 20g/day Crsupplement for the first 5 days followed by 5g/days for the next 5 days of protocol. The WBVT+P group consumed dexterous. The control group neither did any exercise nor consumed any supplement during the protocol. Static balance by standing time on one leg, dynamic balance by TUG test and lower extremity performance by 30-meter walking test, sit and stand test and tandem gait test weremeasured. Paired sample t-test and one way ANOVAwere used for data analysis (α=0.05. Results: Our results showed that dynamic balance, lower body performance in 30- meter walking and tandem gait improved in experimental groups. However, ANOVA did not show any significant increase in static balance (P=0.514, dynamic balance (P=0.153, lower body performance in 30-meter walking test (P=0.339, sit and stand test (P=0.578 and tandem gait (P=0.151. Conclusion: In conclusion, it seems that WBVT plus Cr supplementation improves some of the motor fitness factors in elderly males during a short time.

Full Text Available To document knowledge and attitudes regarding sexuality and sexual practices of male adolescent high school students in Lima, Peru, a self-administered, anonymous survey was completed by 991 male adolescents aged 12-19 as part of a School-Based Sex Education Intervention model. Questions concerned sociodemographic information; family characteristics; personal activities; knowledge and attitudes regarding sexuality; sexual experience; and contraceptive use. Knowledge related to sexuality was limited. Males tended to mainly discuss sexuality with their male peers (49.8%. Attitudes towards sexual activity and condom use were largely positive, although some males expressed ambivalent feelings towards the latter. Of the sample, 43% had ever had sex; age at first sexual intercourse was 13 years. While 88% of the sample would use condoms, 74% also gave reasons for not using them. Sexual activity was related to age, ever having repeated a grade, living with only one parent or in a mixed family, activities such as going to parties, use of alcohol, tobacco, and drugs, and viewing pornographic videos or magazines. Many male adolescents were at risk of causing an unintended pregnancy or acquiring an STD.

Full Text Available Background The present research examined the mediating role of self-efficacy in the association between perceived maternal and paternal parental attitudes and health behaviours of males and females in emerging adulthood. Parental attitudes shape children’s self-esteem, positive self-image, and self-competence. This may affect their physical health and health behaviours throughout their lives. Participants and procedure A total of 147 (mean age: 19.70, SD = 0.85, 68.7% females participants took part in the study. They completed several questionnaires measuring health behaviours, perceived parental attitudes, and self-efficacy: the Inventory of Health Behaviours, the Retrospective Assessment of Parental Attitude, and the General Self-Efficacy Scale. Results We found that that female participants exhibited healthier eating habits but lower self-efficacy than male participants did. Accepting and autonomy granting maternal and paternal parental attitudes predicted a positive health attitude (of both male and female participants, preventive behaviours (of male participants, and healthy eating habits (of male participants. As predicted, emerging adults’ self-efficacy mediated the relationship between their health behaviours and perceived parental attitudes. However, the mediation patterns were different for female and male participants. Conclusions The quality of perceived parental attitudes and self-efficacy are important for health-related lifestyle choices among emerging adults. Mothers and fathers may play different roles in the formation of health behaviours.

Shmyrov, A.; Shmyrov, V.; Shymanchuk, D.

2017-10-01

This article considers the motion of a celestial body within the restricted three-body problem of the Sun-Earth system. The equations of controlled coupled attitude-orbit motion in the neighborhood of collinear libration point L1 are investigated. The translational orbital motion of a celestial body is described using Hill's equations of circular restricted three-body problem of the Sun-Earth system. Rotational orbital motion is described using Euler's dynamic equations and quaternion kinematic equation. We investigate the problem of stability of celestial body rotational orbital motion in relative equilibrium positions and stabilization of celestial body rotational orbital motion with proposed control laws in the neighborhood of collinear libration point L1. To study stabilization problem, Lyapunov function is constructed in the form of the sum of the kinetic energy and special "kinematic function" of the Rodriguez-Hamiltonian parameters. Numerical modeling of the controlled rotational motion of a celestial body at libration point L1 is carried out. The numerical characteristics of the control parameters and rotational motion are given.

Levin, James; Seymour Fowler, H.

The purpose of this study was to collect and analyze data on sexual differences in secondary school students' attitudes towards science. Attitudinal differences were also analyzed for the independent variables of science programs and grade levels. Data were collected from 988 students using a modified version of the Fennema-Sherman Mathematics Attitude Scales to represent attitudes toward science. Reliabilities of the modified science subscales were all high ( > 0.83). Multivariate analysis of variance (MANOVA) was used to analyze the data for the main and interaction effects of the independent variables of sex (male, female), grade level (10th, 11th, 12th), and science program (advanced placement, academic, general, terminal). Significant differences (p Scale, Science as a Male Domain Scale, and Teacher Scale. Although not significant, males evidenced more positive attitudes on all the remaining five subscales. Eleventh graders evidenced significantly more positive attitudes than tenth graders on all but the Effectance Motivation Scale. Students in 11th grade had more positive attitudes than 12th-grade students on all scales but Science as a Male Domain Scale; however, these differences were not significant. Tenth graders differed significantly from 12th graders on three subscales; Science Usefulness Scale, Confidence in Learning Science Scale, and Teacher Scale. Positive attitudes decreased from advanced placement to terminal programs. Academic students did not differ significantly from general students except on the Father Scale; however, they were significantly different (more positive) from the terminal students for all subscales. General students were also significantly different from terminal students except on the three subscales of Attitudes Toward Success in Science, Science as a Male Domain, and Effectance Motivation.

The "spare parts person"? Conceptions of the human body and their implications for public attitudes towards organ donation and organ sale

Science.gov (United States)

Schweda, Mark; Schicktanz, Silke

2009-01-01

Background The increasing debate on financial incentives for organ donation raises concerns about a "commodification of the human body". Philosophical-ethical stances on this development depend on assumptions concerning the body and how people think about it. In our qualitative empirical study we analyze public attitudes towards organ donation in their specific relation to conceptions of the human body in four European countries (Cyprus, Germany, the Netherlands and Sweden). This approach aims at a more context-sensitive picture of what "commodification of the body" can mean in concrete clinical decisions concerning organ donation. Results We find that moral intuitions concerning organ donation are rooted in various conceptions of the human body and its relation to the self: a) the body as a mechanical object owned by the self, b) the body as a part of a higher order embodying the self, and c) the body as a hierarchy of organs constitutive of the self. Conclusion The language of commodification is much too simple to capture what is at stake in everyday life intuitions about organ donation and organ sale. We discuss how the plurality of underlying body-self conceptions can be taken into account in the ethical debate, pointing out consequences for an anthropologically informed approach and for a liberal perspective.

Cytogenetic studies from past decades have shown that interphase cells of female cats contain a densely stained chromatin mass in their nuclei called as Barr bodies (BBs) named after the scientist Murray Barr. BBs are unique chromatin structures formed due to the condensation of the X-chromosome. Many psychopathic disorders originate from defective genes including the multiple X syndromes. Males with extra X-chromosome generally present with severe personality disorder. The present study was conducted to determine the presence of extra X-chromosome in male jail inmates through the detection of BB in peripheral blood and buccal smear. Study included 100 male subjects (fifty jail inmates and fifty controls), after obtaining the consent, peripheral blood smears (PBS) and buccal smears (BS) were prepared and stained using Leishman's and cresyl violet stain respectively. One hundred neutrophils in PBS and epithelial cells in BS were screened for detection of the BB; accumulated data were tabulated and statistically analyzed using t-test and Chi-square test. 60% of cases in PBS and 36% in BS showed positivity for the presence of BB in jail inmates as compared to 14% of cases in PBS and none in BS were positive for BB in controls. Presence of BB in male suggests increased likelihood of criminal tendencies. Further studies are to be carried out to compare the results with karyotyping.

The present study aimed to investigate the relationship between ORTO-15 score and obsessive-compulsive symptoms, disordered eating patterns and body uneasiness among female and male university students and to examine the predictive model of ORTO-15 in both groups. One hundred and twenty students participated in the present study (mean age 22.74 years, SD 7.31). The ORTO-15 test, the Maudsley Obsessive-Compulsive Questionnaire, the Eating Attitudes Test-26 and the Body Uneasiness Test were used for the present study. Our results revealed no gender differences in ORTO-15 score. Our results show, rather unexpectedly, that in female students lower scores, corresponding to greater severity, were related to less pathological body image discomfort and obsessive-compulsive signs, while in male students, lower ORTO-15 scores were related to less pathological eating patterns, as behaviors and symptoms. Further studies regarding the relationship between ON and anorexia nervosa, as well as obsessive-compulsive symptoms, are needed to better understand the causality.

Full Text Available Background: Cultural and traditional norms in the community can have an impact on gender equity. This can be reflected on attitude of both men and women towards domestic violence against women. Gender differences in knowledge and attitude of medical staff about domestic violence can affect their role dealing with battered women. Objective: The current study was formulated to compare knowledge and attitude of male and female medical staff about domestic violence against women. Methods: To achieve this aim, a sample of 1553 health care workers was interviewed out of 2516 allocated for this study with an overall response rate of 61.7%. The target population for this study was all physicians and nurses in the primary health care centers in Kuwait. Results: The results of the current study revealed that female medical primary health care workers tended to have a higher knowledge score about violence against women than male staff (72.8 + 9.8% compared with 68.6 + 10.3%. They also had a higher overall attitude score than males (59.9 + 13.7% compared with 57.8 + 22.4%. Multivariate analysis showed that gender was a significant predictor, after adjusting for other confounding factors, of the overall knowledge, attitude and outcome scores of violence against women. No significant difference was revealed between gender and the barrier domain of violence. Conclusion: Female health care workers tended to have a better knowledge score about definition of domestic violence against women than male medical staff. Females also tended to accept hitting of wives by their husbands if there was a good reason more than males. There is a need to improve both knowledge and attitude of primary health care workers about domestic violence against women.

The aim of this study was to examine the effects of perceived parental attitudes on children's discernment of cigarettes. The study sample consisted of 250 children attending grades 6, 7 and 8. Data were collected via a socio-demographic survey questionnaire, the Parental Attitude Scale (PAS) and the Decisional Balance Scale (DBS). Data analysis covered percentages, medians, one-way analysis of variance (ANOVA) and post-hoc tests using a statistical package. There were 250 participants; 117 were male, 133 were female. The mean age was 13.1 ± 0.98 for the females and 13.3 ± 0.88 for the males. A statistically significant difference was found in the children's mean scores for 'pros' subscale on the Decisional Balance Scale (DBS) according to perceived parental attitudes (F=3.172, p=0.025). There were no statistically significant differences in the DBS 'cons' subscale scores by perceived parental attitudes. It was determined that while perceived parental attitudes affect children's views on advantages of smoking, they have no effect on children's views on its disadvantages.

This study aims to examine the link between male perpetration of teen dating violence (TDV) and neighborhood violence, as well as associations with gender attitudes and perceived peer and neighborhood norms related to violence among a sample of urban adolescent boys. Participants of this cross-sectional study (N = 275) were between the ages of 14 and 20 years and recruited from urban community health centers. Crude and adjusted logistic and linear regression models were used to examine TDV perpetration in relation to (a) neighborhood violence involvement, (b) perceptions of peer violence, (c) perceptions of neighborhood violence, and (d) gender attitudes. Slightly more than one in four (28%) boys reported at least one form of TDV perpetration; among boys who have ever had sex, almost half (45%) reported at least one form of TDV perpetration. In logistic and linear regression models adjusted for demographics, boys who reported TDV perpetration were more likely to report involvement in neighborhood violence (odds ratio (OR) = 3.1; 95% confidence interval (CI) = 1.7-5.5), beliefs that their friends have perpetrated TDV (OR = 2.7; 95%CI = 1.4-5.1), perceptions of violent activity within their neighborhood (OR = 3.0; 95%CI = 1.4-6.3), and greater support of traditional gender norms (β = 3.2, p = 0.002). The findings suggest that efforts are needed to address boys' behaviors related to the perpetration of multiple forms of violence and require explicit efforts to reduce perceived norms of violence perpetration as well as problematic gender attitudes (e.g., increasing support for gender equity) across boys' life contexts.

Prevention programs for body image and eating disorders on University campuses: a review of large, controlled interventions.

Science.gov (United States)

Yager, Zali; O'Dea, Jennifer A

2008-06-01

Body dissatisfaction, dieting, eating disorders and exercise disorders are prevalent among male and female university students worldwide. Male students are also increasingly adopting health-damaging, body-image-related behaviors such as excessive weight lifting, body building and steroid abuse. Given the severity and difficulty of treating eating disorders, prevention of these problems is a recognized public health goal. Health promotion and health education programs have been conducted in the university setting since the mid 1980s, but few have achieved significant improvements in target health attitudes and behaviors. In this paper, 27 large, randomized and controlled health promotion and health education programs to improve body dissatisfaction, dieting and disordered eating and exercise behaviors of male and female college students are reviewed. In general, health education programs to improve body image and prevent eating disorders in the university setting have been limited by small sample sizes and the exclusion of male students. The majority of studies were conducted among either female undergraduate psychology students or women that were recruited using on-campus advertising. The latter reduces the ability to generalize results to the whole university population, or the general community. In addition, there has been a paucity of longitudinal studies that are methodologically sound, as only 82% (22/27) of interventions included in the review used random assignment of groups, and only 52% (n = 14) included follow-up testing. Information-based, cognitive behavioral and psycho-educational approaches have been the least effective at improving body image and eating problems among university students. Successful elements for future initiatives are identified as taking a media literacy- and dissonance-based educational approach, incorporating health education activities that build self-esteem, and using computers and the internet as a delivery medium.

Hsieh, Huey-Hong; Chang, Chia-Ming; Liu, Li-Wei; Huang, Hsiu-Chin

2018-05-11

Background : Self-rated health (SRH) is consistent with objective health status and can serve as a global measure of health status in the general population. The purpose of this study is to find the connections of dietary habits, leisure-time exercise, exercise attitude, and body mass index (BMI) to SRH among college students. Methods : The "dietary⁻exercise attitude and SRH" questionnaire was developed to investigate college students in Taiwan through the Internet. Partial least squares structural equation modeling (PLS-SEM) was used to test the relationship among them. Results : The reliability and validity were confirmed using PLS-SEM. The results found exercise habits, dietary habits, and BMI explained 26.5% of SRH. Poor dietary habits and being overweight led to bad health status (negative path coefficients to SRH). Additionally, the study found that positive exercise attitude had a positive relationship with exercise habits. Conclusions : Based on the results, college students should be well-informed of the potential threat of poor dietary habits and being overweight to health and should improve their attitude with respect to exercise so as to prevent overweight-related diseases.

Male Snakes Allocate Time and Energy according to Individual Energetic Status: Body Condition, Steroid Hormones, and Reproductive Behavior in Timber Rattlesnakes, Crotalus horridus.

Science.gov (United States)

Lind, Craig M; Beaupre, Steven J

2015-01-01

Life-history theory predicts that organisms will hedge current reproductive investment against potential costs in terms of survivorship and future fecundity. However, little is known regarding the endocrine mechanisms underlying bet-hedging strategies in free-ranging male vertebrates. We examined the relationships among individual energetic status, steroid hormones, mate search, and reproductive behavior in free-ranging male timber rattlesnakes. Snakes were monitored over four active seasons in order to test two hypotheses: (1) males adjust the amount of time and energy allocated toward reproduction according to the level of individual energy stores, and (2) observed condition-dependent reproductive allocation is associated with circulating concentrations of steroid hormones (testosterone and corticosterone) thought to regulate reproductive behaviors in vertebrates. A positive relationship between body condition and testosterone was observed in both the field and the laboratory. Male mate search effort was positively correlated with both body condition and testosterone. Body condition and testosterone concentrations were negatively related to time allocated toward foraging during the breeding season. A strong effect of year was observed in the analysis of testosterone and search effort, suggesting that multiple environmental factors impact hormone production and reproductive investment. Corticosterone was not related to any measured variable. Therefore, our results did not indicate a clear role of corticosterone in mediating observed relationships between energetic status and behavior. Observed relationships are consistent with the hypothesis that males allocate time and energy toward reproduction according to individual energetic status and that testosterone plays a role in mediating the trade-off between current reproductive investment and residual reproductive value.

Commonly used dating violence prevention programs assume that promotion of more egalitarian gender role attitudes will prevent dating violence perpetration. Empirical research examining this assumption, however, is limited and inconsistent. The current study examined the longitudinal association between gender role attitudes and physical dating violence perpetration among adolescent boys (n=577; 14% Black, 5% other race/ethnicity) and examined whether injunctive (i.e., acceptance of dating vi...

Japanese attitudes toward assisted procreation.

Shirai, Yasuko

1993-01-01

Based on the present results, the following points are suggested: First, there are significant attitudinal differences [in Japan] on new reproductive technologies between infertile couples and married laypersons; laypersons' attitudes were not so affirmative as those of infertile couples. Second, among the group of infertile couples, male respondents showed more affirmative attitudes toward assisted procreation than female respondents. Third, the main reason for approving of new reproductive technologies was that "it is a treatment for infertility," while the main reasoning of those who disapproved of them was that "it conflicts with the way of nature."

This study examines the nutritional and metabolic cue-induced modulation of the reproductive performance response of female goats to the male effect. During natural anoestrus, 48 Blanca Andaluza does were isolated from bucks for 45 days and distributed into two groups: (1) low body weight (BW)/low body condition score (BCS) animals (LL-gain group, N=18), which were fed 1.9 times their maintenance requirements; and (2) high BW/high BCS animals (HH-loss group, N=30), which were fed 0.4 times their maintenance requirements. Following isolation, oestrous activity was recorded daily by visual observation of the marks left by harness-equipped males. Weekly blood samples were taken for the determination of progesterone, glucose, insulin, non-esterified fatty acids (NEFAs) and leptin concentrations. Fecundity, fertility, prolificacy and productivity were also determined. Significantly greater ovarian and oestrous responses, and productivity, were observed in the LL-gain group compared to the HH-loss group (Preproductive performances of does subjected to the male effect in spring are poorer in those with a decreasing BW and BCS and better in those with increasing scores. This might be explained by the differences between groups in terms of their plasma insulin concentrations. The NEFA concentration was clearly modified by introduction to the males.

Luo, T Y

1996-09-01

This study, with the use of a questionnaire survey method, examined the characteristics of sexual harassment experiences and the dynamics of the attitudes toward sexual harassment among male and female workers in Taipei. An occupationally representative sample of male and female workers was recruited to participate in the survey. The findings showed that 1 in 4 workers in Taipei experienced some sort of sexual harassment in the workplace, 36% (n = 493) of the surveyed women and 13% (n = 415) of the surveyed men reported experiencing workplace sexual harassment. The most frequently reported type of sexual harassment was unwanted sexual jokes/comments, followed by unwanted deliberate body contact, and unwanted requests/pressure for a date. The major source of sexual harassment came from coworkers of the opposite sex. Majority of the alleged victims attributed their sexual harassment incident to insensitivity of the initiator. In being consistent with previous research, the study established three attitudinal models toward sexual harassment among Chinese workers: the victim-blame/trivialization model, the natural/biological explanation, and the power/manipulation model. The study found no consistent relationship between the self-rated attitudes toward sexual harassment and the self-reported sexual harassment experiences.

Sexual Selection on male cuticular hydrocarbons via male-male competition and female choice.

Traditional views of sexual selection assumed that male-male competition and female mate choice work in harmony, selecting upon the same traits in the same direction. However, we now know that this is not always the case and that these two mechanisms often impose conflicting selection on male sexual traits. Cuticular hydrocarbons (CHCs) have been shown to be linked to both social dominance and male attractiveness in several insect species. However, although several studies have estimated the strength and form of sexual selection imposed on male CHCs by female mate choice, none have established whether these chemical traits are also subject to sexual selection via male-male competition. Using a multivariate selection analysis, we estimate and compare sexual selection exerted by male-male competition and female mate choice on male CHC composition in the broad-horned flour beetle Gnatocerus cornutus. We show that male-male competition exerts strong linear selection on both overall CHC abundance and body size in males, while female mate choice exerts a mixture of linear and nonlinear selection, targeting not just the overall amount of CHCs expressed but the relative abundance of specific hydrocarbons as well. We discuss the potential implications of this antagonistic selection with regard to male reproductive success. © 2016 The Authors.

This study investigated the students’ attitude towards science and the effect of gender on students’ attitude. A total of 77 secondary school students participated in this study that were selected randomly in cluster, from various schools of Bandung, Indonesia. The attitude questionnaire consisted of 23 items related to four dimensions: enjoyment, self-confidence, value and motivation. Data collected by questionnaire were converted into interval scale using Method of Successive Interval (MSI) and further analyzed using Statistical Package for Social Science (SPSS). The use of MSI for analyzing the questionnaire data is still fairly new. Results showed that students’ positive attitude towards science was at medium level and there was no significant difference in attitude towards science between the female and male students. The study is of great significance to science teachers in order not to be gender biased when teaching science learning.

Kalman Filter for Spinning Spacecraft Attitude Estimation

Markley, F. Landis; Sedlak, Joseph E.

2008-01-01

This paper presents a Kalman filter using a seven-component attitude state vector comprising the angular momentum components in an inertial reference frame, the angular momentum components in the body frame, and a rotation angle. The relatively slow variation of these parameters makes this parameterization advantageous for spinning spacecraft attitude estimation. The filter accounts for the constraint that the magnitude of the angular momentum vector is the same in the inertial and body frames by employing a reduced six-component error state. Four variants of the filter, defined by different choices for the reduced error state, are tested against a quaternion-based filter using simulated data for the THEMIS mission. Three of these variants choose three of the components of the error state to be the infinitesimal attitude error angles, facilitating the computation of measurement sensitivity matrices and causing the usual 3x3 attitude covariance matrix to be a submatrix of the 6x6 covariance of the error state. These variants differ in their choice for the other three components of the error state. The variant employing the infinitesimal attitude error angles and the angular momentum components in an inertial reference frame as the error state shows the best combination of robustness and efficiency in the simulations. Attitude estimation results using THEMIS flight data are also presented.

A Go/No-go approach to uncovering implicit attitudes towards safe and risky driving

Self-report measures of driving-related attitudes and beliefs miss potentially important precursors of driving behaviour, namely, automatic and implicit thought processes. The present study used an adapted Go/No-go Association Task to measure implicit thought without relying on the participants......' self-reports. Implicit attitudes towards safe and risky driving were measured in 53 Danish drivers (31 female, 22 male). Further, we explored the relationship between implicit attitudes towards risky and safe driving, and self-reported driving behaviour and skills. The results suggest that implicit...... attitudes were significantly related to self-reported driving behaviour and skills for male (but not female) drivers. Pending future research with larger sample sizes, the difference between implicit attitudes towards safe versus risky driving that we observed may contribute to a greater theoretical...

The health-related behaviors and attitudes of student nurses

Science.gov (United States)

Vowell, Maribeth

Nurses are an important component of primary medical care, and patient education is a common and important role of most nurses. Patient education and positive role modeling by nurses have the potential to influence patients' life style choices and the serious diseases that may be affected by those choices. A greater understanding of the ways nurses think about their own health could help facilitate healthier choices for them and in their patients. The purpose of this inquiry was to examine the experiences, attitudes and beliefs of student nurses related to their personal health, and to investigate those experiences, attitudes and beliefs as they relate to their education, relationships, values and career choice. The purpose was achieved through phenomenological interviews with eleven senior nursing students, nine females and two males, encouraging them to provide in as much detail as possible their attitudes and values about their personal health. The interviews were tape recorded, transcribed verbatim, and phenomenologically analyzed. A thematic structure emerged such that the nursing students experiences were represented by the four interrelated themes of caring for myself/caring for others ; I control my health/my world controls my health; I have energy/I'm tired; and feeling good/looking good. The contextual grounds for the themes that emerged during the analysis were the Body and Time. This structure was presented in terms of its relationship to health education, other research and to current theory.

We examined the relationship between adolescents' perceptions of their close friends' attitudes about substance use, and their own use of cigarettes, alcohol, and marijuana. Using data from the 2010 National Survey on Drug Use and Health, a multistage area probability sample sponsored by the Substance Abuse and Mental Health Services Administration (n = 17,865), we tested the direct and moderating effects of subgroups of race and gender on perceptions of adolescents' close friends on past month substance use. Significant effects were found on peer attitudes influencing substance use for all race and gender subgroups. Close friends' attitudes of indifference were associated with increased substance use and disapproval associated with reduced use, controlling for age, income, family structure, and adolescents' own attitudes of risk of substance use. Significant moderating effects of peer attitudes on cigarette and marijuana use were found for both gender and race moderators. Conditional effects of the moderation by race were also examined for gender subgroups. The moderating effect of race on close friends' attitudes impacting cigarette and marijuana use was stronger in magnitude and significance for females compared to males. Female marijuana and cigarette use was more influenced by close friends' attitudes than males, and whites were more influenced by their close friends than Hispanics and blacks. White females are more susceptible to close friends' attitudes on cigarette use as compared to white males and youth of other races. Implications for socially oriented preventive interventions are discussed.

Teen Dating Violence in French-speaking Switzerland: Attitudes and Experiences

2015-07-01

Full Text Available Research on dating violence has tended to focus on North American college students. This study innovates with data collected in Switzerland from a sample of 132 school pupils and vocational education students aged 14 to 22 using a self-administered questionnaire. The study investigates relationships between attitudes and experiences about dating violence and the effect of gender. Biases against women were common in the sample. Females reported less endorsement of patriarchal attitudes about women’s roles, but both genders reported similar levels of disparagement of women. Participants reported high rates of physical violence perpetration (41.9 percent and victimization (48.8 percent. Pro-violence attitudes were related to psychological and physical perpetration as well as physical victimization. For female respondents, essentialist beliefs about women’s innate abilities appear more persistent than beliefs about appropriate roles. Male participants endorsed both types of gender stereotypes at high rates. Male-perpetrated violence was perceived less favorably than female-perpetrated violence. Our data suggest that general attitudes toward violence are the most consistent predictor of physical and psychological aggression within dating relationships. More attention needs to be paid to subtypes among attitudes on women and violence, which past research assumed were monolithic. This study shows the need for prevention programs to address pro-violence attitudes.
