Project description:Student evaluation of teaching (SET) is widely used to assess teaching effectiveness in higher education and can significantly influence professors' career outcomes. Although earlier evidence suggests SET may suffer from biases due to the gender of professors, there is a lack of large-scale examination to understand how and why gender disparities occur in SET. This study aims to address this gap in SET by analyzing approximately 9 million SET reviews from RateMyProfessors.com under the theoretical frameworks of role congruity theory and shifting standards theory. Our multiple linear regression analysis of the SET numerical ratings confirms that women professors are generally rated lower than men in many fields. Using the Dunning log-likelihood test, we show that words used in student comments vary by the gender of professors. We then use BERTopic to extract the most frequent topics from one- and five-star reviews. Our regression analysis based on the topics reveals that the probabilities of specific topics appearing in SET comments are significantly associated with professors' genders, which aligns with gender role expectations. Furtherly, sentiment analysis indicates that women professors' comments are more positively or negatively polarized than men's across most extracted topics, suggesting students' evaluative standards are subject to professors' gender. These findings contextualize the gender gap in SET ratings and caution the usage of SET in related decision-making to avoid potential systematic biases towards women professors.

Project description:Obesity during adolescence is associated with cardiovascular mortality in adulthood. The adverse obesity-related cardiometabolic risk profile is already observed in adolescence. We aimed to examine possible gender differences in cardiometabolic risk factors and lifestyle behaviors among adolescents with severe obesity, hypothesizing that boys would have both a higher prevalence of the metabolic syndrome as well as less healthy lifestyle behaviors than girls.Cross-sectional study of treatment-seeking adolescents with severe obesity who attended the Morbid Obesity Centre at Vestfold Hospital Trust and who were consecutively enrolled in the Vestfold Register of Obese Children between September 2009 and September 2015. A total of 313 adolescents aged 12 to 18 years were recruited, whereof 268 subjects (49% boys) completed a food and activity frequency questionnaire and were included in the analysis.Mean (SD) age, BMI and BMI SDS were 15 (1.6) years, 38.6 (5.9) kg/m2 and 3.5 (0.6). Levels of LDL cholesterol, fasting insulin and glucose and diastolic blood pressure (DBP) did not differ between genders. Compared to girls, boys had significantly higher triglycerides (p =?0.037) and systolic blood pressure (SBP) (p =?0.003), as well as lower HDL cholesterol (p =?0.002). The metabolic syndrome was present in 27% of the boys and 19% of the girls (p =?0.140), and the prevalence of high DBP, dyslipidemia and dysglycemia also did not differ significantly between genders. The prevalence of high SBP was higher in boys than in girls (19% vs. 9%, p =?0.021). Gender was associated with a number of lifestyle habits, as a larger proportions of boys had higher screen time (p =?0.032), more regular breakfast eating (p =?0.023), higher intake of sugar sweetened soda (p =?0.036), and lower intake of vegetables than girls (p =?0.011). By contrast, physical activity level and intake of fruit and berries did not differ between genders.Male treatment-seeking adolescents with severe obesity had a more unfavorable set of metabolic and behavioral risk factors for cardiovascular disease than girls. Our results indicate that lifestyle behavioral markers should be thoroughly assessed in both genders, and possible gender-related differences in risk profile should be taken into account in future treatment programs.

Project description:This study investigated the associations between traditional gender roles (TGRs) and substance use among early adolescents in Mexico's largest cities. The sample of seventh grade students (n = 4,932) attended 26 public schools in Mexico City, Guadalajara, or Monterrey in 2014. Outcomes included recent alcohol, binge drinking, cigarette and marijuana use, and lifetime poly-substance use; substance-use intentions, norms, attitudes, and expectancies; and substance-use exposure (peer use, offers) and resistance (refusal confidence, refusal skills, and decision-making skills). A TGR scale assessed endorsement of a polarized gender division of family labor and power. As hypothesized, among males, TGRs were consistently associated with poorer outcomes, and this association was usually stronger for males than for females. In contrast, among females there was no evidence that TGRs were associated with desirable outcomes. Contrary to expectations, TGRs predicted poorer outcomes for both females and males, and to equivalent degrees, for binge drinking, cigarette use, positive substance-use expectancies, and friends' approval of substance use, and they predicted poorer outcomes for females but not for males on parental disapproval of substance use and drug-resistance skills. Interpretations highlight the persisting aspects of TGRs in the family and conflicting messages for females as Mexico undergoes changes in its gender order.

Project description:BackgroundBeing bullied online is associated with being bullied in school. However, links between online bullying and violence-related experiences are minimally understood. We evaluated potential disparities in these associations to illuminate opportunities to reduce school-based violence.MethodsWe used five cohorts of Youth Risk Behavior Survey national cross-sectional data (2011-2019, Ntotal = 73 074). We used survey-weighted logistic and multinomial models to examine links between online bullying and five school-based violence-related experiences: offline bullying, weapon carrying, avoiding school due to feeling unsafe, being threatened/injured with a weapon, and physical fighting. We examined interactions by sex, race/ethnicity, and sexual identity.ResultsBeing bullied online was positively associated with all offline violence-related behaviors. Groups with stronger associations between online bullying and physical fighting, including boys, adolescents whose sexual identity was gay/lesbian or unsure, and many adolescents of color (Black, Hispanic/Latino, and Asian/Pacific Islander adolescents), had stronger associations between online bullying and either weapon carrying or avoiding school.ConclusionsOnline bullying is not an isolated harmful experience; many marginalized adolescents who experience online bullying are more likely to be targeted in school, feel unsafe, get in fights, and carry weapons. Reduction of online bullying should be prioritized as part of a comprehensive school-based violence prevention strategy.

Project description:PurposeSexual and gender minority (SGM) adolescents are more likely to become victims of bullying and harassment than heterosexual, cisgender adolescents, but little is known about the contextual details of these victimization experiences. This study aims to examine by whom and where adolescents are bullied or harassed, to whom adolescents report such victimization, and whether these experiences differ between SGM and heterosexual, cisgender adolescents.MethodsParticipants in this nationally representative study were 29,879 students (mean age = 14.1) from 136 Dutch middle/high schools across grades 7-12 (14.5% sexual minority, 2.7% gender minority) who completed a survey about their school-based experiences.ResultsPerpetrators of victimization of SGM students were more often teachers and school staff compared with heterosexual, cisgender adolescents. Furthermore, SGM students experienced victimization in private locations (in the rest- or changing rooms/parking lots, at home), more often than heterosexual, cisgender students. Finally, SGM students felt less safe than their heterosexual, cisgender peers to report these experiences to teachers or parents, and were more likely to report their experiences to the police or the school janitor. SGM students who reported victimization experiences were less likely to receive support: the problems were less often acted on and persisted more often than those of heterosexual, cisgender students.ConclusionsSGM adolescents are not only victimized more often, but also by different perpetrators (teachers, other school staff) and in more private places. Their victimization is also less likely to be recognized or acted on by those responsible for adolescent's safety: teachers or parents.

Project description:Research has demonstrated that adolescents of the digital age engage in developmental tasks by interacting with others in both online and offline environments. However, no studies have investigated how adolescents develop their identity, a crucial developmental task, by engaging in online and offline prosocial behaviors. To address this research gap, we examined the role of online and offline prosocial behavior in identity development during adolescence using variable- and person-centered approaches. The participants were 608 individuals in early adolescence (50.2% girls; age range = 12-13 years, Mage = 12.75 years, SD = 0.43) and 594 individuals in middle adolescence (50.3% girls; age range = 15-16 years, Mage = 15.79 years, SD = 0.41) in Japan. They completed questionnaires to measure identity development, online and offline prosocial behavior, and demographic characteristics. The results from the variable-centered approach (i.e., identity dimensions) revealed that both online and offline prosocial behaviors were positively related to commitments and proactive explorations in early and middle adolescence. The findings from the person-centered approach (i.e., identity statuses) demonstrated that early and middle adolescents with higher levels of online prosocial behavior were more likely to show searching moratorium than all other identity statuses, whereas those with higher levels of offline prosocial behavior were more likely to show achievement than troubled diffusion, carefree diffusion, and undifferentiated. Consistent with both variable- and person-centered approaches, these findings highlight that online prosocial behavior can be a new resource for identity development in adolescence. Moreover, the results suggest that online prosocial behaviors lead to identity status in the process of maturing identity and that offline prosocial behavior is necessary to become more mature identity status. Regarding practical implications, educating adolescents on digital media literacy, including supportive behavior in online environments, is crucial to gradually exploring their identity. In addition, for adolescents to develop more mature identity, adults should create in-person environments in which they participate in offline prosocial behavior. The limitations of our findings with respect to the online and offline prosocial behavior scale items are discussed.

Project description:BackgroundLifestyle-related diseases, including diabetes, cardiovascular disease, and some cancers represent the greatest global health threat. Greater insight into health needs and beliefs, using broad community samples, is vital to reduce the burden of chronic disease. This study aimed to investigate gender, age, screening practices, health beliefs, and perceived future health needs for healthy ageing.MethodsRandom probability sampling using self-completion surveys in 1456 adults residing in Australia.ResultsScreening behaviors were associated with gender and age. Men and women >51 years were more likely (27%) to have screening health checks than those <50 years (2%). Factors nominated to influence health were lifestyle (92%), relationships (82%), and environment (80%). Women were more likely to nominate preparedness to have an annual health check, willingness to seek advice from their medical practitioner and to attend education sessions. Numerous health fears were associated with ageing, however participants were more likely to have a financial (72%) rather than a health plan (42%). More women and participants >51 years wanted information regarding illness prevention than men or those aged <30 years.ConclusionAge and gender are associated with health related behaviors. Optimal health is perceived as a priority, yet often this perception is not translated into preventative action. These findings will inform future research and policy makers as we strive towards a healthier ageing society and the prevention of chronic disease.

Project description:BackgroundPublic engagement in the research of environmental epidemiological problems is becoming an important measure to empower citizens to identify the local environmental and health problems and to explain different environmental exposures affect estimates for males and females. This HORIZON2020 CitieS-Health Kaunas Pilot study examines the relationship between urban built and social environment, health behaviors, and health in men and women.MethodsThis cross-sectional study included 1086 18-74-year-old participants residing in 11 districts of Kaunas city, Lithuania. Using GIS, we measured traffic flow, noise, NO2, PM2.5, PM10, and greenness NDVI for the participants' home addresses, determined participants' perceptions of environmental quality, linked this information with personal sociodemographic data, and used multivariate logistic regression to assess the associations with health issues (physician-diagnosed chronic disease and self-rated general health) in men and women.ResultsMen and women similar rated the quality of the neighborhood environment, except for air pollution and satisfaction with the public transport in the district. The traffic-related health associations were stronger for women than for men. The prevalence of poor health increased with the increasing age of men and women, yet no significant differences between gender health risks were found in the total sample. Perceived air pollution, irregular visits to green space, and chronic diseases were consistently associated with poor health risks in men and women, yet part-time jobs and low income had a higher impact on women's poor health.ConclusionsQuality of the built neighborhood, air pollution, irregular visits to the green space, and chronic disease had a joint effect on the magnitude of the prevalence of poor health in men and women. Our results suggest that decreasing air pollution and improving the urban built neighborhood supporting citizens' physical activity in green spaces, might reduce health risks for all.

Project description:BackgroundsMore males than females play video games and develop problems with gaming. However, little is known regarding how males and females who game on the Internet may differ with respect to neural responses to gaming cues. Behavioral and functional magnetic resonance imaging (fMRI) data were recorded from 40 female and 68 male Internet gamers. This study included three components including participation in a pre-gaming cue-craving task, 30 min of online gaming and a post-gaming cue-elicited-craving task. Group differences were examined at pre-gaming, post-gaming and post- vs pre-gaming times. Correlations between brain responses and behavioral performance were calculated. : Gaming-related cues elicited higher cravings in male vs female subjects. Prior to gaming, males demonstrated greater activations in the striatum, orbitofrontal cortex (OFC), inferior frontal cortex and bilateral declive. Following gaming, male subjects demonstrated greater activations in the medial frontal gyrus and bilateral middle temporal gyri. In a post-pre comparison, male subjects demonstrated greater thalamic activation than did female subjects. Short-term gaming elicited in males vs females more craving-related activations to gaming cues. These results suggest neural mechanisms for why males may be more vulnerable than females in developing Internet gaming disorder.

Project description:BackgroundIn sub-Saharan Africa HIV transmission is a major challenge in adolescents, especially among girls and those living in urban settings. Major international efforts have aimed at reducing sexual transmission of HIV. This analysis aims to assess the trends in HIV prevalence by gender in adolescents, as well as urban-rural disparities.MethodsHIV prevalence data at ages 15-19 years were obtained for 31 countries with a national survey since 2010 and for 23 countries with one survey circa 2005 and a recent survey circa 2015. Country medians and average annual rates of changes were used to summarize the trends for two subregions in sub-Saharan Africa, Eastern and Southern Africa and West and Central Africa, which largely correspond with higher and lower HIV prevalence countries. Data on HIV incidence at ages 15-24 and prevalence at 5-9 and 10-14 years were reviewed from 11 recent national surveys. Trends in urban-rural disparities in HIV prevalence and selected indicators of sexual and HIV testing behaviours were assessed for females and males 15-24 years, using the same surveys.ResultsHIV prevalence among girls 15-19 years declined in eastern and Southern Africa from 5.7 to 2.6% during 2005-2015 (country median), corresponding with an average annual rate of reduction of 6.5% per year. Among boys, the median HIV prevalence declined from 2.1 to 1.2%. Changes were also observed in West and Central Africa where median HIV prevalence among girls decreased from 0.7 to 0.4% (average annual rate of reduction 5.9%), but not for boys (0.3%). Girl-boy differences at 10-14 years were small with a country median HIV of 1.0% and 1.3%, respectively. Urban females and males 15-24 had at least 1.5 times higher HIV prevalence than their rural counterparts in both subregions, and since the urban-rural declines were similar, the gaps persisted during 2005-2015.ConclusionsHIV prevalence among adolescents declined in almost all countries during the last decade, in both urban and rural settings. The urban-rural gap persisted and HIV transmission to girls, but not boys, is still a major challenge in Eastern and Southern African countries.
