Exploring the role of positive body image in healthy orthorexia and orthorexia nervosa: A gender comparison

Current scholarship on orthorexia nervosa remains undecided about the role of body image in this novel eating disorder. This study aimed to explore the role of positive body image in differentiating between healthy orthorexia and orthorexia nervosa and assess how this might differ for men and women. A total of 814 participants (67.1% women; age M = 40.30, SD = 14.50) completed the Teruel Orthorexia scale, as well as measures of embodiment, intuitive eating, body appreciation and functionality appreciation. A cluster analysis revealed four distinct profiles characterized by high healthy orthorexia and low orthorexia nervosa; low healthy orthorexia and low orthorexia nervosa; low healthy orthorexia and high orthorexia nervosa; and high healthy orthorexia and high orthorexia nervosa. A MANOVA identified significant differences for positive body image between these four clusters, as well as that there were no significant differences between men and women for healthy orthorexia and orthorexia nervosa, despite men scoring significantly higher than women on all measures of positive body image. Cluster × gender interaction effects were found for intuitive eating, functionality appreciation, body appreciation and experience of embodiment. These findings indicate that the role of positive body image in healthy orthorexia and orthorexia nervosa may differ for men and women, making these relationships worthy of further exploration.

Gender Disparity in Breast Cancer: A Veteran Population-Based Comparison

BACKGROUND

Male breast cancer (MBC) comprises <1% of all cancers and continues to rise. Because of rarity, there is paucity in the literature; therefore, management of MBC is generalized from female breast cancer (FBC).

METHODS

Data from 152 VA Medical Centers were used to analyze the database of Veteran patient with breast cancer diagnosed between 1998 and 2016 using biostatistical software (SAS 9.3). Our primary objective is to compare patient's demographics, breast cancer characteristics, and outcomes for male and female Veterans.

FINDING

In total, 8864 patients' records were reviewed;1528 MBC were compared with 7336 FBC with a mean follow up time of 5.5 years (SD 4.17). The mean age at diagnosis was 68.6 years and 57.3 years for MBC and FBC, respectively (P < .0001). Higher numbers of MBC patients (95%) were >50 years of age compared to FBC patients (72%). More MBC patients (16.8 vs. 9.1% and 9 vs. 4%) presented with higher disease stage (III and IV, respectively). Estrogen receptor-positive tumors were more common in MBC (59 versus 52%). Hormonal treatment was received by 27% of MBC versus 19% FBC; chemotherapy 21.3% versus 41.5% and radiation 23.5% versus 60.9%. Forty-two percent MBC and 20% FBC Veterans died during study. Male patients had higher death rate 1.285 (95% CI: 1.150, 1.434, P < .0001) compared to females after adjusting data for age, race, stage, and grade.

INTERPRETATION

To the best of our knowledge, this is the largest comparison series of MBC and FBC to date in the Veterans population. The higher mortality rate in MBC patients may be due to late presentation, higher stage at the time of diagnosis and/or tumor biology. Veteran's exposures to hazardous materials during their military deployments as an additional factor for worse prognosis need further investigation.

Gender differences in externalizing and internalizing problems in Singaporean children and adolescents with attention-deficit/hyperactivity disorder

BACKGROUND

Studies on gender differences in attention-deficit/hyperactivity disorder (ADHD) comorbidities in the Asian populations have been limited and previous studies have shown inconclusive findings. Singapore is a city-state country in Southeast Asia with a population of 5.7 million. This study examined gender differences in internalizing and externalizing problems in Singaporean children and adolescents with ADHD. The plausible social factors underlying the gender differences were discussed.

METHODS

A total of 773 participants (aged 6 to 18, 88% males) newly diagnosed with ADHD were recruited from the largest public child and adolescent psychiatric center in Singapore. Their internalizing and externalizing problems were assessed using the Child Behavioral Checklist and Teacher's Report Form by parents and teachers respectively. Demographics and relevant social factors were collected using parent questionnaires.

RESULTS

Females with ADHD were reported to have less delinquent and aggressive behavior but more depressive symptoms than their male counterparts, similar to findings in the Western literature. Gender remained a significant predictor of externalizing problem after controlling for other factors. Lower socioeconomic status and parental use of physical punishment were significant predictors of both internalizing and externalizing problems.

CONCLUSIONS

Gender differences in ADHD comorbidities do exist in the Asian clinical population. The lack of externalizing symptoms in females with ADHD has made timely referral and diagnosis challenging. More research is needed in understanding the gender differences in ADHD and the biopsychosocial mechanism underlying the differences in order to improve the detection of ADHD in females.

A gender-based comparison of academic rank and scholarly productivity in academic neurological surgery

The number of women pursuing training opportunities in neurological surgery has increased, although they are still underrepresented at senior positions relative to junior academic ranks. Research productivity is an important component of the academic advancement process. We sought to use the h-index, a bibliometric previously analyzed among neurological surgeons, to evaluate whether there are gender differences in academic rank and research productivity among academic neurological surgeons. The h-index was calculated for 1052 academic neurological surgeons from 84 institutions, and organized by gender and academic rank. Overall men had statistically higher research productivity (mean 13.3) than their female colleagues (mean 9.5), as measured by the h-index, in the overall sample (p<0.0007). When separating by academic rank, there were no statistical differences (p>0.05) in h-index at the assistant professor (mean 7.2 male, 6.3 female), associate professor (11.2 male, 10.8 female), and professor (20.0 male, 18.0 female) levels based on gender. There was insufficient data to determine significance at the chairperson rank, as there was only one female chairperson. Although overall gender differences in scholarly productivity were detected, these differences did not reach statistical significance upon controlling for academic rank. Women were grossly underrepresented at the level of chairpersons in this sample of 1052 academic neurological surgeons, likely a result of the low proportion of females in this specialty. Future studies may be needed to investigate gender-specific research trends for neurosurgical residents, a cohort that in recent years has seen increased representation by women.
