Sex and gender reporting in global health: new editorial policies

Integrating sex and gender into biomedical research requires policy and culture change

Most biomedical, health and care research does not adequately account for sex and gender dimensions of health and illness. Overlooking and disregarding the influence of sex and gender in research reduces scientific rigour and reproducibility, which leads to less effective treatments and worse health outcomes for all, particularly women and sex and gender diverse people. Historically, there has been minimal sex and gender policy innovation in UK medical research. To address this, stakeholders from across the UK research sector have been collaborating since spring 2023 to co-design a sex and gender policy framework to be implemented by research funders, as part of the MESSAGE (Medical Science Sex and Gender Equity) project. In the first Policy Lab, held in London in May 2023, 50 participants, including representatives from funding organisations, medical journals, regulators, clinicians, academics and people with lived experience, identified two key priorities for future action: 1) A whole system approach to policy change, and 2) Technical capacity-building and wider culture change efforts. In pursuing these priorities and collaborating cross-sectorally, UK stakeholders are engaged in an internationally innovative approach aimed at realising sustainable and impactful sex and gender policy change. Drawing on MESSAGE Policy Lab discussions, we set out key actions needed for the UK research sector to embed meaningful accounting for sex and gender as a new norm for research practice.

Protected characteristics reported in pulmonary rehabilitation: a scoping review

BACKGROUND

An individual's characteristics are reported to influence access, completion and outcomes of pulmonary rehabilitation and may contribute to health inequalities. Many countries have policies to promote equity among individuals' characteristics, including the UK Equality Act 2010 which lists nine protected characteristics (age, disability, gender reassignment, marriage and civil partnership, pregnancy and maternity, race, religion or belief, sex and sexual orientation).

OBJECTIVES

To describe the extent to which UK Equality Act 2010 protected characteristics have been collected and reported in UK studies and audits of pulmonary rehabilitation.

METHODS

A scoping review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping Reviews guidelines was conducted using five databases. UK studies and audits collecting data on pulmonary rehabilitation from 1 October 2010 (date of Equality Act 2010 inception) were eligible. The protected characteristics collected and how they were reported were extracted.

RESULTS

Out of 45 included studies and audits (41 studies and four audits), 98% (k=44) reported age. Sex was reported in 40% (k=18), and 20% (k=9) reported gender with only male and female categories. Half (50%, k=2) of audits reported gender with male, female and transgender categories. Race was reported through ethnicity in 2% (k=1) of studies and 75% (k=3) of audits. No studies or audits explicitly reported disability, but all reported measures indicating disease severity (e.g. forced expiratory volume in 1 s % predicted: 67%, k=30). No studies or audits reported marriage and civil partnership, pregnancy and maternity, religion or belief or sexual orientation.

CONCLUSIONS

Protected characteristics are not commonly reported or are inconsistently reported in UK pulmonary rehabilitation studies and audits. Without reporting these characteristics, health inequalities in pulmonary rehabilitation will remain unclear.

A roadmap for sex- and gender-disaggregated health research

Sex and gender are fundamental aspects of health and wellbeing. Yet many research studies fail to consider sex or gender differences, and even when they do this is often limited to merely cataloguing such differences in the makeup of study populations. The evidence on sex and gender differences is thus incomplete in most areas of medicine. This article presents a roadmap for the systematic conduct of sex- and gender-disaggregated health research. We distinguish three phases: the exploration of sex and gender differences in disease risk, presentation, diagnosis, treatment, and outcomes; explaining any found differences by revealing the underlying mechanisms; and translation of the implications of such differences to policy and practice. For each phase, we provide critical methodological considerations and practical examples are provided, taken primarily from the field of cardiovascular disease. We also discuss key overarching themes and terminology that are at the essence of any study evaluating the relevance of sex and gender in health. Here, we limit ourselves to binary sex and gender in order to produce a coherent, succinct narrative. Further disaggregation by sex and gender separately and which recognises intersex, non-binary, and gender-diverse identities, as well as other aspects of intersectionality, can build on this basic minimum level of disaggregation. We envision that uptake of this roadmap, together with wider policy and educational activities, will aid researchers to systematically explore and explain relevant sex and gender differences in health and will aid educators, clinicians, and policymakers to translate the outcomes of research in the most effective and meaningful way, for the benefit of all.

Foregrounding women and household dynamics to inform Article 17: a qualitative description analysis of tobacco farming households in Mozambique

PURPOSE

This paper examines the intrahousehold dynamics between women and men present in tobacco farming households in Mozambique. Attention to the experiences and realities of the smallholder farmers is crucial for understanding approaches to alternative livelihoods. Intrahousehold dynamics can provide important insights into how these households and their members view tobacco production and engage with the political economy of tobacco farming, how they make decisions, and the rationale and values behind these decisions.

METHODS

Data were collected through single-gender focus group discussions (n=8) with 108 participants (men=57, women=51). Analysis was informed by a qualitative description methodology. This research presents a gender-based analysis examining the perspectives, roles, decision-making processes and desires of female and male tobacco farmers in four key tobacco-growing districts in Mozambique.

FINDINGS

Throughout this paper, women are found to hold leverage and influence in tobacco farming households, and this leverage is in part gained via the necessity of women's unpaid labour in achieving profitability in tobacco farming. Both women and men are also found to strongly desire and pursue the well-being of the household.

CONCLUSION

Women hold agency within tobacco-growing households and participate in decision-making processes regarding tobacco agriculture. Women should be included in future tobacco control policies and programmes pertaining to Article 17.

Sex and gender in infection and immunity: addressing the bottlenecks from basic science to public health and clinical applications

Although sex and gender are recognized as major determinants of health and immunity, their role is rarely considered in clinical practice and public health. We identified six bottlenecks preventing the inclusion of sex and gender considerations from basic science to clinical practice, precision medicine and public health policies. (i) A terminology-related bottleneck, linked to the definitions of sex and gender themselves, and the lack of consensus on how to evaluate gender. (ii) A data-related bottleneck, due to gaps in sex-disaggregated data, data on trans/non-binary people and gender identity. (iii) A translational bottleneck, limited by animal models and the underrepresentation of gender minorities in biomedical studies. (iv) A statistical bottleneck, with inappropriate statistical analyses and results interpretation. (v) An ethical bottleneck posed by the underrepresentation of pregnant people and gender minorities in clinical studies. (vi) A structural bottleneck, as systemic bias and discriminations affect not only academic research but also decision makers. We specify guidelines for researchers, scientific journals, funding agencies and academic institutions to address these bottlenecks. Following such guidelines will support the development of more efficient and equitable care strategies for all.

Gender and urban-rural influences on antibiotic purchasing and prescription use in retail drug shops: a one health study

INTRODUCTION

Few studies have reported antibiotic purchases from retail drug shops in relation to gender in low and middle-income countries (LMICs). Using a One Health approach, we aimed to examine gender dimensions of antibiotic purchases for humans and animals and use of prescriptions in retail drug shops in Bangladesh.

METHODS

We conducted customer observations in 20 drug shops in one rural and one urban area. Customer gender, antibiotic purchases, and prescription use were recorded during a four-hour observation (2 sessions of 2 hours) in each shop. We included drug shops selling human medicine (n = 15); animal medicine (n = 3), and shops selling both human and animal medicine (n = 2).

RESULTS

Of 582 observations, 31.6% of drug shop customers were women. Women comprised almost half of customers (47.1%) in urban drug shops but only 17.2% of customers in rural drug shops (p < 0.001). Antibiotic purchases were more common in urban than rural shops (21.6% versus 12.2% of all transactions, p = 0.003). Only a quarter (26.0%) of customers who purchased antibiotics used a prescription. Prescription use for antibiotics was more likely among women than men (odds ratio (OR) = 4.04, 95% CI 1.55, 10.55) and more likely among urban compared to rural customers (OR = 4.31 95% CI 1.34, 13.84). After adjusting for urban-rural locality, women remained more likely to use a prescription than men (adjusted OR = 3.38, 95% CI 1.26, 9.09) but this was in part due to antibiotics bought by men for animals without prescription. Customers in drug shops selling animal medicine had the lowest use of prescriptions for antibiotics (4.8% of antibiotic purchases).

CONCLUSION

This study found that nearly three-quarters of all antibiotics sold were without prescription, including antibiotics on the list of critically important antimicrobials for human medicine. Men attending drug shops were more likely to purchase antibiotics without a prescription compared to women, while women customers were underrepresented in rural drug shops. Antibiotic stewardship initiatives in the community need to consider gender and urban-rural dimensions of drug shop uptake and prescription use for antibiotics in both human and animal medicine. Such initiatives could strengthen National Action Plans.

Disparities in COVID-19 Impacts on Work Hours and Career Satisfaction by Gender and Race among Scientists in the US: An Online Survey Study

The impact of the COVID-19 pandemic on work–life balance may be unequal between female and male scientists. Further information is needed regarding whether the working conditions and career satisfaction for women and racialized scientists are disproportionately affected by the pandemic. This online survey collected data from 1171 scientists in science, technology, engineering, mathematics (STEM), and medicine (STEMM), public health, or other areas of science/engineering working in the US to examine potential disparities in changes in work hours and career satisfaction by gender and race/ethnicity. A significantly higher percentage of women reported increased work hours compared to men. Women, especially racialized women, experienced disproportionately higher increases in teaching and service than the other groups, which contributed to the increased total work hours for women. Satisfaction with the current career progress was lowest for racialized women compared to their counterparts. Our results indicate that the pandemic has inequitably affected allocation of workloads and career satisfaction by gender and race in scientific fields. Institutions of higher education and other research organizations should acknowledge the gender/race differences in science before and during the pandemic to better support the career development and achievement of all scientists, especially women and even more so racialized women.

Impacts of the COVID-19 pandemic on scientists' productivity in science, technology, engineering, mathematics (STEM), and medicine fields

While studies suggested adverse impacts of COVID-19 on scientific outputs and work routines for scientists, more evidence is required to understand detailed obstacles challenging scientists' work and productivity during the pandemic, including how different people are affected (e.g., by gender). This online survey-based thematic analysis investigated how the pandemic affected scientists' perception of scientific and academic productivity in the science, technology, engineering, and mathematics (STEM) and medicine fields. The analysis examined if inequitable changes in duties and responsibilities for caregiving for children, family, and/or households exist between scientists who are mothers compared to scientists who are fathers or non-parents. The survey collected data from 2548 survey responses in six languages across 132 countries. Results indicate that many scientists suffered from delays and restrictions on research activities and administrations due to the lockdown of institutions, as well as increased workloads from adapting to online teaching environment. Caregiving responsibility for children and family increased, which compromised time for academic efforts, especially due to the temporary shutdown of social supports. Higher percentages of female parent participants than male parent participants expressed such increased burdens indicating unequal divisions of caregiving between women and men. A range of physical and mental health issues was identified mainly due to overworking and isolation. Despite numerous obstacles, some participants reported advantages during the pandemic including the efficiency of online teaching, increased funding for COVID-related research, application of alternative research methodologies, and fluidity of the workday from not commuting. Findings imply the need for rapid institutional support to aid various academic activities and diminish gender inequity in career development among academicians, highlighting how crisis can exacerbate existing inequalities.

Gender perspective in COVID-19. SESPAS Report 2022

We failed to adequately launch a gender transformative response to COVID-19 pandemic, data by sex on a variety of indicators for most countries are hard to find. Some symptoms reported as common of COVID-19 infection, are more prominent in men, while others are more prominent in women, one cannot with certainty exclude that some of the differences observed could be due to gender bias in the management of cases in health services. The gender implications of the pandemic reach wide and far. Inequalities can be further aggravated as sex and gender intersect with other axes of inequality. The SAGER guidelines exemplify an effort to improve reporting of sex and gender dimensions and encouraging researchers to integrate these aspects in the research design. these observations and emerging evidence about the persistent gender-blind approach to COVID-19 is a wake-up call to change course. National Gender Equality Institutions can be central in ensuring gender matters are considered in government responses. COVID-19 pandemic is an opportunity to reverse the trend and take action to apply an intersectional feminist approach to global health that enables a just and equal world where everyone's health and wellbeing matter.

Differences in self-perception of productivity and mental health among the STEMM-field scientists during the COVID-19 pandemic by sex and status as a parent: A survey in six languages

The COVID-19 pandemic has caused unprecedented challenges for working conditions for scientists, but little is known for how the associations of these challenges with scientists' mental health and productivity differ by sex and status as a parent. This online survey study in six languages collected data from 4,494 scientists in Science, Technology, Engineering, Mathematics, and Medicine fields across 132 countries during October-December 2021. We compared the type of challenges for work, changes in work hours, and perception in productivity during the pandemic by sex and status as a parent (children <18 years living at home). Regression analyses analyzed the impacts of changed working conditions and work-life factors on productivity and mental health. We found that the percentage of participants with increased work hours was the highest in female participants, especially without children. Disproportionately higher increases in work hours were found for teaching and administration in women than men and for research/fundraising in non-parent participants than parent participants (p-value<0.001). Female participants were more concerned about the negative impacts of the pandemic on publications and long-term career progress, and less satisfied with their career progress than their male counterparts. There were differences in the type of institutional actions for the pandemic across study regions. The identified obstacles for work and home-life factors were associated with higher risks of experiencing depression, anxiety, and stress. Decision makers should consider the gender differences in the pandemic's adverse impacts on productivity in establishing equitable actions for career progress for scientists during pandemics.

Non-fatal injuries among boys and girls presenting to Red Cross War Memorial Children’s Hospital, Cape Town

Background. In South Africa (SA), road traffic injuries, homicides and burns are the leading causes of injury-related deaths among children. Injury-related deaths are well documented for SA, but this is not the case for non-fatal injuries.Objectives. To describe the non-fatal injuries sustained among children aged 0 - 13 years, to identify any significant sex differences by age group, cause of injury, admission status and injury severity. Methods. The trauma unit database from 1997 to 2016 at Red Cross War Memorial Children’s Hospital, Cape Town, was utilised for this analysis. The prevalence of injuries and the boy/girl ratios with 95% confidence intervals (CIs) were reported.Results. Analysis indicated significant differences by sex for individual injury causes (transport, assault, burns, falls and other injuries), age group, injury severity and admission status. Moderately severe injuries were largely caused by burns, while severe injuries were mostly transport related. Boys had significantly higher proportions of all injury causes. The boy/girl ratio was lowest for assault (1:18), where significantly more girls aged 1 - 3 and 4 - 6 years were injured. Rape/sexual assault was 5.5 times higher for girls, with a significantly higher proportion of moderate-severity injuries (87%; 95% CI 84.7 - 89.4). Conclusion. The study findings call for a more targeted prevention response for boy and girl children. Interventions should be targeted at the prevention of burns, traffic collisions and interpersonal violence, in particular sexual assaults against girls.

Sex and gender disparities in patients with advanced gastroesophageal adenocarcinoma: data from the AGAMENON-SEOM registry

Background

Recommendations for research articles include the use of the term sex when reporting biological factors and gender for identities or psychosocial or cultural factors. There is an increasing awareness of incorporating the effect of sex and gender on cancer outcomes. Thus, these types of analyses for advanced gastroesophageal adenocarcinoma are relevant.

Patients and methods

Patients with advanced gastroesophageal adenocarcinoma from the Spanish AGAMENON-SEOM registry treated with first-line combination chemotherapy were selected. Epidemiology, characteristics of the disease, treatment selection, and results were examined according to sex.

Results

This analysis included 3274 advanced gastroesophageal adenocarcinoma patients treated with combination chemotherapy between 2008 and 2021: 2313 (70.7%) men and 961 (29.3%) women. Tumors in females were more frequently HER2-negative (67.8% versus 60.8%; P < 0.0001), grade 3 (45.4% versus 36.8%; P < 0.001), diffuse (43.3% versus 26.5%; P < 0.0001), and signet ring cell histology (40.5 versus 23.9%; P < 0.0001). Peritoneal spread was more common in women (58.6% versus 38.9%; P < 0.0001), while liver burden was lower (58.9% versus 71.1%; P < 0.0001). There were no significant differences in treatment recommendation. Treatment doses, density, and duration were comparable between sexes. Women experienced more diarrhea (46% versus 37%; P < 0.0001), neutropenia (51% versus 43%; P < 0.0001), and anemia (62% versus 57%; P < 0.0001). After a median 59.6-month follow-up [95% confidence interval (CI) 54.5-70.8], there were no statistically significant differences between the sexes in progression-free survival [6.21 months (95% CI 5.8-6.5 months) versus 6.08 months (95% CI 5.8-6.3 months); log-rank test, χ² = 0.1, 1 df, P = 0.8] or in overall survival [10.6 months (95% CI 9.8-11.1 months) versus 10.9 months (95% CI 10.4-11.4 months); log-rank test: χ² = 0.6, 1 df, P = 0.5].

Conclusion

This sex analysis of patients with advanced gastroesophageal adenocarcinoma from the AGAMENON-SEOM registry receiving first-line polychemotherapy found no differences in survival. Although women had worse prognostic histopathology, metastatic disease pattern, and greater toxicity, treatment allocation and compliance were equivalent.

•

Sex and gender are determinants of health inequalities and may affect treatments, tolerability, and therapeutic outcomes.

•

According to sex, subtle biological and clinical differences exist in advanced gastroesophageal adenocarcinoma.

•

Women with advanced gastroesophageal adenocarcinoma experience greater toxicity with therapeutic results comparable with men.

•

Stratification and analysis by sex in studies of gastroesophageal adenocarcinoma should be considered.

An Evaluation of Sex- and Gender-Based Analyses in Oncology Clinical Trials

BACKGROUND

The objective of this study was to evaluate whether sex- and gender-based analyses and proper sex- and gender-terminology were used in oncology trials leading to regulatory drug approval.

METHODS

The Food and Drug Administration (FDA) Hematology/Oncology Approvals and Safety Notifications page was used to identify all anti-cancer therapies that received FDA approval between 2012 and 2019. The trials used to support FDA-drug approval were collected along with all available supplemental tables and study protocols. Documents were reviewed to determine if there was a plan to analyze results according to sex and gender and to determine if consistent sex and gender terminology were used.

RESULTS

128 randomized-controlled trials were identified corresponding to a cancer medicine which received FDA-approval. No study specified how sex and gender were collected or analyzed. No study reported any information on the gender of participants. Sex and gender terminology was used inconsistently at least once in 76% (97/128) of studies. Among the 102 trials for non-sex-specific cancer sites, 89% (91/102) presented disaggregated survival outcome data by sex. No study presented disaggregated toxicity data by sex or gender.

CONCLUSION

The majority of pivotal clinical trials in oncology fail to account for the important distinction between sex and gender and conflate sex and gender terminology. More rigor in designing clinical trials to include sex and gender based analyses and more care in using sex and gender terms in the cancer literature is needed. These efforts are essential to improve the reproducibility, generalizability, and inclusiveness of cancer research.

Gender expression is associated with selection of uterine preservation or hysterectomy for pelvic organ prolapse surgery: Novel methodology for sex- and gender-based analysis in gynecologic research

OBJECTIVE

To explore whether patient characteristics were associated with gender expression, and to further determine impact of gender expression on patient selection of hysterectomy or uterine-preservation in pelvic organ prolapse (POP) surgery.

METHODS

Within a prospective cohort, a self-reported gender expression tool classified patients as expressing gender polar (i.e., reporting only feminine traits) or non-polar gender scores (i.e., reporting feminine and masculine traits). Multivariate modeling explored associations of gender expression with traditional socio-demographic variables, and with selection of hysterectomy or uterine-preserving surgery. Descriptive statistics of socio-demographic variables were reported by frequency, proportion and mean (SD).

RESULTS

177 participants completed the gender score questionnaire. Overall, the sample had a more feminine gender expression with the majority of respondents classified as gender polar (67.23%, n = 119). Participants with non-polar gender scores were 2.53 times (95% 1.05-6.09) more likely to choose uterine preservation versus hysterectomy-based surgery. Gender polarity was weakly associated with age, but no other sociodemographic variables.

CONCLUSION

Gender expression is not tightly associated with socio-demographic variables, and is thus a novel measurement in gynecologic research. Gender polarity appears to be associated with choice to undergo hysterectomy. Further research is required to understand this relationship and implications in clinical outcomes.

Using genderize.io to infer the gender of first names: how to improve the accuracy of the inference

Objective

We recently showed that genderize.io is not a sufficiently powerful gender detection tool due to a large number of nonclassifications. In the present study, we aimed to assess whether the accuracy of inference by genderize.io can be improved by manipulating the first names in the database.

Methods

We used a database containing the first names, surnames, and gender of 6,131 physicians practicing in a multicultural country (Switzerland). We uploaded the original CSV file (file #1), the file obtained after removing all diacritic marks, such as accents and cedilla (file #2), and the file obtained after removing all diacritic marks and retaining only the first term of the compound first names (file #3). For each file, we computed three performance metrics: proportion of misclassifications (errorCodedWithoutNA), proportion of nonclassifications (naCoded), and proportion of misclassifications and nonclassifications (errorCoded).

Results

naCoded, which was high for file #1 (16.4%), was reduced after data manipulation (file #2: 11.7%, file #3: 0.4%). As the increase in the number of misclassifications was small, the overall performance of genderize.io (i.e., errorCoded) improved, especially for file #3 (file #1: 17.7%, file #2: 13.0%, and file #3: 2.3%).

Conclusions

A relatively simple manipulation of the data improved the accuracy of gender inference by genderize.io. We recommend using genderize.io only with files that were modified in this way.

Systematic Review of Sex and Gender Effects in Traumatic Brain Injury: Equity in Clinical and Functional Outcomes

Background: Although traumatic brain injury (TBI) is a leading cause of death and disability in male and female patients worldwide, little is known about the effect of sex and gender on TBI outcomes.

Objectives: This systematic review summarizes the evidence on the effect of sex and gender on core TBI outcomes.

Methods: All English-language studies from six literature databases that addressed core outcomes in adults with TBI and included sex or gender, TBI severity, and age in their analyses were considered eligible. Two reviewers extracted data, and two reviewers assessed study quality using tools recommended by the National Institutes of Health. The results were sorted according to time post-injury, injury severity, gender equity ranking of the study's country of origin, and outcomes studied. The results from the included studies were grouped based on the approach taken in reporting their respective findings.

Results and Limitations: Of 172 articles assessed, 58 studies were selected, comprising 1, 265, 955 participants with TBI (67% male across all studies) of all injury severities. All studies were conducted in countries with a very high or high human development index, while the Gender Inequality Index (GII) varied. While the heterogeneity across studies limited any meaningful conclusions with respect to the role of sex and gender, we did observe that as gender equality ranking improved, differences between male and female participants in outcomes would diminish. Inclusion of social equity parameters in the studies was limited.

Conclusions and Implications: The non-uniform findings observed bring forth the need to develop and use a comprehensive and consistent methodology in the study of sex and gender post-TBI, incorporating social equity parameters to uncover the potential social underpinnings of gender effects on health and functional outcomes.

Long-term costs and cost-effectiveness of adjunctive corticosteroids for patients with septic shock in New Zealand

OBJECTIVE

The aim of the study was to determine whether adjunctive hydrocortisone reduced healthcare expenditure and was cost-effective compared with placebo in New Zealand patients in the Adjunctive Glucocorticoid Therapy in Patients with Septic Shock (ADRENAL) trial.

DESIGN

This is a health economic analysis using data linkage to New Zealand Ministry of Health databases to determine resource use, costs, and cost-effectiveness for a 24-month period.

SETTING

The study was conducted in New Zealand.

PARTICIPANTS AND INTERVENTION

Patients with septic shock were randomised to receive a 7-day continuous infusion of 200 mg of hydrocortisone or placebo in the ADRENAL trial.

MAIN OUTCOME MEASURES

Healthcare expenditure was associated with all hospital admissions, emergency department presentations, outpatient visits, and pharmacy expenditure. Effectiveness outcomes included mortality at 6 months and 24 months and quality of life at 6 months. Cost-effectiveness outcomes were assessed with reference to quality-adjusted life years gained at 6 months and life years gained at 24 months.

RESULTS

Of 3800 patients in the ADRENAL trial, 419 (11.0%) were eligible, and 405 (96.7% of those eligible) were included. The mean total costs per patient over 24 months were $143,627 ± 100,890 and $143,772 ± 97,117 for the hydrocortisone and placebo groups, respectively (p = 0.99). Intensive care unit costs for the index admission were $50,492 and $62,288 per patient for the hydrocortisone and placebo groups, respectively (p = 0.09). The mean number of quality-adjusted life years gained at 6 months and mean number of life years gained at 24 months was not significantly different by treatment group, and the probability of hydrocortisone being cost-effective was 55% at 24 months.

CONCLUSIONS

In New Zealand, adjunctive hydrocortisone did not reduce total healthcare expenditure or improve outcomes compared with placebo in patients with septic shock.

Performance of gender detection tools: a comparative study of name-to-gender inference services

Objective:

To evaluate the performance of gender detection tools that allow the uploading of files (e.g., Excel or CSV files) containing first names, are usable by researchers without advanced computer skills, and are at least partially free of charge.

Methods:

The study was conducted using four physician datasets (total number of physicians: 6,131; 50.3% female) from Switzerland, a multilingual country. Four gender detection tools met the inclusion criteria: three partially free (Gender API, NamSor, and genderize.io) and one completely free (Wiki-Gendersort). For each tool, we recorded the number of correct classifications (i.e., correct gender assigned to a name), misclassifications (i.e., wrong gender assigned to a name), and nonclassifications (i.e., no gender assigned). We computed three metrics: the proportion of misclassifications excluding nonclassifications (errorCodedWithoutNA), the proportion of nonclassifications (naCoded), and the proportion of misclassifications and nonclassifications (errorCoded).

Results:

The proportion of misclassifications was low for all four gender detection tools (errorCodedWithoutNA between 1.5 and 2.2%). By contrast, the proportion of unrecognized names (naCoded) varied: 0% for NamSor, 0.3% for Gender API, 4.5% for Wiki-Gendersort, and 16.4% for genderize.io. Using errorCoded, which penalizes both types of error equally, we obtained the following results: Gender API 1.8%, NamSor 2.0%, Wiki-Gendersort 6.6%, and genderize.io 17.7%.

Conclusions:

Gender API and NamSor were the most accurate tools. Genderize.io led to a high number of nonclassifications. Wiki-Gendersort may be a good compromise for researchers wishing to use a completely free tool. Other studies would be useful to evaluate the performance of these tools in other populations (e.g., Asian).

The gender and geography of publishing: a review of sex/gender reporting and author representation in leading general medical and global health journals

Introduction

Diverse gender and geographical representation matters in research. We aimed to review medical and global health journals’ sex/gender reporting, and the gender and geography of authorship.

Methods

542 research and non-research articles from 14 selected journals were reviewed using a retrospective survey design. Paper screening and systematic data extraction was conducted with descriptive statistics and regression analyses calculated from the coded data. Outcome measures were journal characteristics, the extent to which published articles met sex/gender reporting guidelines, plus author gender and location of their affiliated institution.

Results

Five of the fourteen journals explicitly encourage sex/gender analysis in their author instructions, but this did not lead to increased sex/gender reporting beyond the gender of study participants (OR=3.69; p=0.000 (CI 1.79 to 7.60)). Just over half of research articles presented some level of sex/gender analysis, while 40% mentioned sex/gender in their discussion. Articles with women first and last authors were 2.4 times more likely to discuss sex/gender than articles with men in those positions (p=0.035 (CI 1.062 to 5.348)). First and last authors from high-income countries (HICs) were 19 times as prevalent as authors from low-income countries; and women from low-income and middle-income countries were at a disadvantage in terms of the impact factor of the journals they published in.

Conclusion

Global health and medical research fails to consistently apply a sex/gender lens and remains largely the preserve of authors in HIC. Collaborative partnerships and funding support are needed to promote gender-sensitive research and dismantle historical power dynamics in authorship.

A scoping review of female drowning: an underexplored issue in five high-income countries

BACKGROUND

Drowning is a significant public health issue, with females accounting for one third of global drowning deaths. The rate of female drowning has not decreased within high-income countries and presentations to hospital have increased. This scoping review aimed to explore adult female unintentional drowning, including risk factors, clinical treatment and outcomes of females hospitalised for drowning.

METHODS

A systematic search of the literature following the PRISMA-ScR framework was undertaken. The databases OVID MEDLINE, Embase, CINAHL, OVID Emcare, Web of Science, Informit and Scopus were accessed. Study locations of focus were Australia, Canada, New Zealand, the United Kingdom, and the United States. Studies from January 2003 to April 2019 were included. The quality of evidence of included studies was assessed using GRADE guidelines.

RESULTS

The final search results included 14 studies from Australia (n = 4), Canada (n = 1), New Zealand (n = 1), United States (n = 6), United Kingdom (n = 1), and one study reporting data from both Australia and United States. Nine studies reported risk factors for female drowning including age, with the proportion of female drowning incidence increasing with age. Although females are now engaging in risk-taking behaviours associated with drowning that are similar to males, such as consuming alcohol and swimming in unsafe locations, their exposure to risky situations and ways they assess risk, differ. Females are more likely to drown from accidental entry into water, such as in a vehicle during a flood or fall into water. This review found no evidence on the clinical treatment provided to females in hospital after a drowning incident, and only a small number of studies reported the clinical outcomes of females, with inconsistent results (some studies reported better and some no difference in clinical outcomes among females).

CONCLUSION

Adult females are a group vulnerable to drowning, that have lacked attention. There was no single study found which focused solely on female drowning. There is a need for further research to explore female risk factors, the clinical treatment and outcomes of females hospitalised for drowning. This will not only save the lives of females, but also contribute to an overall reduction in drowning.

The cost-effectiveness of adjunctive corticosteroids for patients with septic shock

OBJECTIVE

To determine whether hydrocortisone is a cost-effective treatment for patients with septic shock.

DESIGN

Data linkage-based cost-effectiveness analysis.

SETTING

New South Wales and Queensland intensive care units.

PARTICIPANTS AND INTERVENTION

Patients with septic shock randomly assigned to treatment with hydrocortisone or placebo in the Adjunctive Glucocorticoid Therapy in Patients with Septic Shock (ADRENAL) trial.

MAIN OUTCOME MEASURES

Health-related quality of life at 6 months using the EuroQoL 5-dimension 5-level questionnaire. Data on hospital resource use and costs were obtained by linking the ADRENAL dataset to government administrative health databases. Clinical outcomes included mortality, health-related quality of life, and quality-adjusted life-years gained; economic outcomes included hospital resource use, costs and cost-effectiveness from the health care payer perspective. We also assessed cost-effectiveness by sex. To increase the precision of cost-effectiveness estimates, we conducted unrestricted bootstrapping.

RESULTS

Of 3800 patients in the ADRENAL trial, 1772 (46.6%) were eligible and 1513 (85.4% of those eligible) were included. There was no difference between hydrocortisone or placebo groups in regards to mortality (218/742 [29.4%] v 227/759 [29.9%]; HR, 0.93; 95% CI, 0.78-1.12; P = 0.47), mean number of QALYs gained (0.10 ± 0.09 v 0.10 ± 0.09; P = 0.52), or total hospital costs (A$73 515 ± 61 376 v A$69 748 ± 61 793; mean difference, A$3767; 95% CI, -A$2891 to A$10 425; P = 0.27). The incremental cost of hydrocortisone was A$1 254 078 per quality-adjusted life-year gained. In females, hydrocortisone was cost-effective in 46.2% of bootstrapped replications and in males it was cost-effective in 2.7% of bootstrapped replications.

CONCLUSIONS

Adjunctive hydrocortisone did not significantly affect longer term mortality, health-related quality of life, health care resource use or costs, and is unlikely to be cost-effective.

Gender, women, and the future of tobacco control

Purpose

This paper aims to provide a gendered analysis of the WHO Framework Convention on Tobacco Control (FCTC) benchmarked upon the global commitments to women’s health and well-being in the UN Convention on the Elimination of All Forms of Discrimination against Women (CEDAW) and the Beijing Declaration and Platform for Action. It reviews evidence of the global consequences of neglecting women’s tobacco use and health, as well as analyzes persistent issues related to sex and gender that compromise the efficacy of tobacco control and science. Actionable recommendations are made to the Conference of the Parties to the FCTC and other key stakeholders.

Design/methodology/approach

This paper draws upon empirical studies, literature reviews and global health data at the varying intersections of gender, sex, tobacco and global health.

Findings

The global tobacco control framework and its implementation by state governments have been largely gender blind to date with dire health and economic consequences, including inequitable positive outcomes for men compared to women, and an increase in women’s smoking with associated morbidity and mortality. Gender equitable progress in combatting the tobacco epidemic will not be possible without resolving the gender bias, stigmatization, sexism and lack of intersectionality that plague tobacco control policy, research and interventions for cessation and harm reduction.

Originality/value

This paper provides an updated global overview of current trends in women’s tobacco use and comprehensively details the persistent structural barriers in tobacco control and science that limit their capacity to effectively analyze and address tobacco use and its impact on women.

Sex-Related Differences in the Effects of Sports-Related Concussion: A Review

Sports-related concussion is a serious health challenge, and females are at higher risk of sustaining a sports-related concussion compared to males. Although there are many studies that investigate outcomes following concussion, females remain an understudied population, despite representing a large proportion of the organized sports community. In this review, we provide a summary of studies that investigate sex-related differences in outcome following sports-related concussion. Moreover, we provide an introduction to the methods used to study sex-related differences after sports-related concussion, including common clinical and cognitive measures, neuroimaging techniques, as well as biomarkers. A literature search inclusive of articles published to March 2020 was performed using PubMed. The studies were reviewed and discussed with regard to the methods used. Findings from these studies remain mixed with regard to the effect of sex on clinical symptoms, concussion-related alterations in brain structure and function, and recovery trajectories. Nonetheless, there is initial evidence to suggest that sex-related differences following concussion are important to consider in efforts to develop objective biomarkers for the diagnosis and prognosis of concussion. Additional studies on this topic are, however, clearly needed to improve our understanding of sex-related differences following concussion, as well as to understand their neurobiological underpinnings. Such studies will help pave the way toward more personalized clinical management and treatment of sports-related concussion.

Gender differences in physical activity and sedentary behaviour in adults with intellectual disabilities: A systematic review and meta-analysis

BACKGROUND

Adults with intellectual disabilities are reported to be highly inactive, with research required to understand contributory factors. This systematic review aimed to investigate gender differences in physical activity (PA) and sedentary behaviour (SB) in adults with intellectual disabilities.

METHODS

This systematic review was reported in accordance with PRISMA guidelines. Seven databases were searched up to, and including, January 2018. Screening identified papers that assessed gender-specific PA and/or SB outcomes in adults with intellectual disabilities. Data were synthesized using a narrative synthesis and random effects model meta-analyses.

RESULTS

Twenty-six papers were included; 25 measured PA, and eight assessed SB. Women with intellectual disabilities were least active with a significant overall effect of gender identified. For SB, no consistent gender differences were found.

CONCLUSIONS

Reflecting the general population, men with intellectual disabilities were most active. Intellectual disability research should consider the role of gender to inform future interventions targeting inactivity.

Gender-related differences in care-seeking behaviour for newborns: a systematic review of the evidence in South Asia

Introduction

Data indicate substantial excess mortality among female neonates in South Asia compared with males. We reviewed evidence on sex and gender differences in care-seeking behaviour for neonates as a driver for this.

Methods

We conducted a systematic review of literature published between January 1st, 1996 and August 31st, 2016 in Pubmed, Embase, Eldis and Imsear databases, supplemented by grey literature searches. We included observational and experimental studies, and reviews. Two research team members independently screened titles, abstracts and then full texts for inclusion, with disagreements resolved by consensus. Study quality was assessed using National Institute for Health and Care Excellence (NICE) checklists and summary judgements given using Grading of Recommendations Assessment, Development and Evaluation (GRADE) criteria. Data were extracted into Microsoft Excel.

Results

Of 614 studies initially identified, 17 studies were included. Low quality evidence across several South Asian countries suggests that care-seeking rates for female neonates are lower than males, especially in households with older female children. Parents are more likely to pay more, and seek care from providers perceived as higher quality, for males than females. Evidence on drivers of these care-seeking behaviours is limited. Care-seeking rates are suboptimal, ranging from 20% to 76% across male and female neonates.

Conclusion

Higher mortality observed among female neonates in South Asia may be partly explained by differences in care-seeking behaviour, though good quality evidence on drivers for this is lacking. Further research is needed, but policy interventions to improve awareness of causes of neonatal mortality, and work with households with predominantly female children may yield population health benefits. The social, economic and cultural norms that give greater value and preference to boys over girls must also be challenged through the creation of legislation and policy that support greater gender equality, as well as context-specific strategies in partnership with local influencers to change these practices.

Trends in recruitment of women and reporting of sex differences in large-scale published randomized controlled trials in stroke

Background

Understanding of sex differences, especially in terms of the influence of sex on therapeutic interventions, can lead to improved treatment and management for all.

Aim

We examined temporal and regional trends in female participation and the reporting of sex differences in stroke randomized controlled trials.

Methods

Randomized controlled trials from 1990 to 2018 were identified from ClinicalTrials.gov, using keywords “stroke” and “cerebrovascular accidents.” Studies were selected if they enrolled ≥100 participants, included both sexes and were published trials (identified using PubMed, Google Scholar, and Scopus).

Results

Of 1700 stroke randomized controlled trials identified, 277 were published and eligible for analysis. Overall, these randomized controlled trials enrolled only 40% females, and in the past 10 years, this percentage barely changed, peaking at 41% in 2008–2009 and 2012–2013. North American randomized controlled trials recruited the most women, at 43%, and Asia the lowest, at 40%. Among the 277 randomized controlled trials, 101 (36%) reported results according to sex, of which 91 (33%) were pre-specified analyses. The increasing trend in the number of studies reporting sex-differentiated results from 2008 to 2018 merely paralleled the increase in the number of papers published during the same time period. North American randomized controlled trials most often reported sex-specific results (42%), and Australia and Europe least often (31%).

Conclusion

Little progress has been made in the inclusion of females and the reporting of sex in stroke randomized controlled trials. This highlights the need for key stakeholders, such as funders and journal editors, to provide clear guidance and effective implementation strategies to researchers in the scientific reporting of sex.

Oxidative Stress as Cause, Consequence, or Biomarker of Altered Female Reproduction and Development in the Space Environment

Oxidative stress has been implicated in the pathophysiology of numerous terrestrial disease processes and associated with morbidity following spaceflight. Furthermore, oxidative stress has long been considered a causative agent in adverse reproductive outcomes. The purpose of this review is to summarize the pathogenesis of oxidative stress caused by cosmic radiation and microgravity, review the relationship between oxidative stress and reproductive outcomes in females, and explore what role spaceflight-induced oxidative damage may have on female reproductive and developmental outcomes.
