Enhancing diversity in public health scholarship: the role of publication mentorship

This Supplement, a collaboration between Health Systems Global (HSG) and the Alliance for Health Policy and Systems Research (AHPSR) and Health Policy and Planning (HPP), is the product of a six-month publication mentorship programme aimed at supporting early-career women conducting Health Policy and Systems Research (HPSR) in lowand middle-income countries (LMICs) (AHPSR, 2019). The mentorship programme guided mentees—selected based on a motivation letter and draft abstract—in preparing a high-quality manuscript for a peer-reviewed journal. Topics for submitted papers were restricted to themes identified for the Sixth Global Symposium on Health Systems Research on ‘Re-imagining health systems for better health and social justice’ (HSR, 2020). This editorial will discuss the role of programmes such as publication mentorship in mitigating structural barriers in the career advancement of women, racial and ethnic minorities and others experiencing discrimination and bias. It will also highlight the social justice and equity-oriented themes that connect the papers included in the special issue, demonstrating the importance of amplifying voices that are often underrepresented in scholarship and leadership.


Introduction
This Supplement, a collaboration between Health Systems Global (HSG) and the Alliance for Health Policy and Systems Research (AHPSR) and Health Policy and Planning (HPP), is the product of a six-month publication mentorship programme aimed at supporting early-career women conducting Health Policy and Systems Research (HPSR) in low-and middle-income countries (LMICs) (AHPSR, 2019). The mentorship programme guided mentees-selected based on a motivation letter and draft abstract-in preparing a high-quality manuscript for a peer-reviewed journal. Topics for submitted papers were restricted to themes identified for the Sixth Global Symposium on Health Systems Research on 'Re-imagining health systems for better health and social justice' (HSR, 2020). This editorial will discuss the role of programmes such as publication mentorship in mitigating structural barriers in the career advancement of women, racial and ethnic minorities and others experiencing discrimination and bias. It will also highlight the social justice and equity-oriented themes that connect the papers included in the special issue, demonstrating the importance of amplifying voices that are often underrepresented in scholarship and leadership.

Women in academia
It is well-documented that gender, race, ethnicity, socioeconomic status and other combinations of social identities impede women's progress in the health workforce and restrict access to corridors of power (Hankivsky et al., 2014;Newman et al., 2017;Clark et al., 2018;Moyer et al., 2018;George et al., 2019;WHO, 2019;Yount et al., 2020). For example, while women represent 53% of the world's bachelor's and master's degree graduates and 43% of PhD graduates, they represent only 28% of researchers in all fields, suggesting a high rate of attrition in the academic workforce, limiting diversity of perspective and thus scholarship (Tiedeu et al., 2019).
Women's progress in academic medicine and public health is often impeded by structural barriers and gendered institutions (Edmunds et al., 2016;Howe-Walsh and Turnbull, 2016;Stavroula et al., 2017;Yousaf and Schmiede, 2017;Cameron et al., 2019). Some of the key barriers include gendered stereotypes and bias, imbalanced family and care-taking roles, lack of mentorship and poor organizational support (Edmunds et al., 2016;Corneille et al., 2019;Shreffler et al., 2019). Institutions have begun to implement practices aimed at improving the recruitment, promotion and retention of women and others facing structural barriers. These include institution-wide training in unconscious bias, career development support, childcare services, availability of culturally responsive mentorship, networking opportunities, diversity practices in recruitment and promotion committees and others (Carr et al., 2017).
In academia, high-impact publications continue to serve as a benchmark of productivity, expertise and success. Therefore, gender disparities in the number of publications, especially amongst earlyand mid-career researchers, contribute to inequalities in academic placements and promotions (Mueller et al., 2016;Cooper et al., 2019). This is observable in the rates of assistant versus full professorships across gender and race categories, with fewer women holding full professorships as compared with men, and minority women underrepresented at all levels (Patel et al., 2018). An intersectional lens-accounting for interactions across gender, race, ethnicity, disability and other social identities-is required to improve measures designed to empower those facing structural barriers.

Mentorship as part of the solution
Culturally responsive mentorship is a powerful tool in strengthening capacity and enhancing social capital (Sopher et al., 2015;Campos, 2016;Bertrand Jones et al., 2020). It is important to note that mentorship is not a flawless panacea. For example, without formal and informal structures to ensure equity in mentorship programmes, mentorship roles-seen as 'nurturing'-tend to fall disproportionately to women (Campos, 2016). Furthermore, mentoring relationships are strengthened when connected to wider networks creating cultural shifts in homogenous institutions (DeCastro et al., 2013). Mentorship must be viewed as a two-way relationship whereby the perspectives and experiences of the mentee are treated with respect, leading to meaningful dialogue and debate around culturally responsive tools, approaches and methods in conducting and disseminating

Increasing diversity of thought in scholarship
HPSR is a dynamic field focused on strengthening resilient health systems, addressing systemic barriers, enhancing social justice and leaving no one behind. Therefore, all measures that diversify the field and amplify underrepresented voices can help to enrich its scholarship with new perspectives, approaches and methods. In their commentary on 'Supporting early-career mentorship for women in HPSR: a vital input to building the field', Kwamie and Jalaghonia expand on the significance of mentorship for HPSR and provide insight based on lessons learned from the Alliance-HSG publication mentorship programme. They reflect on positive outcomes from the programme, such as professional development opportunities for both mentors and mentees, as well as limitations, such as short timelines and language barriers. The papers included in this special issue include a wide range of equity-oriented topics affecting health system performance and outcomes. These include intersectoral and systemic barriers and facilitators affecting individual-level behaviours, health system structures affecting equity in service delivery, as well as institutions and policies inhibiting representation and inclusion.

Barriers and facilitators affecting individual behaviours
Tran et al. identify links between poor reproductive health outcomes and Intimate Partner Violence (IPV) in Bangladesh, highlighting the role of education and food security in mitigating these outcomes. Luhumyo et al. examine IPV prevalence in Western Kenya and its links to prematurity as a perinatal outcome among survivors, also highlighting the role of education and formal employment. Nanyonga et al. examine barriers and facilitators for nurses in leadership, demonstrating the importance of organizational culture in enhancing nurses' ability to lead and engage in policy decisions. Faith et al. assess utilization of inactivated polio vaccination among caregivers with children in Uganda, identifying a need for social mobilization and outreach to improve vaccination coverage.
Health system structures affecting equitable service delivery

Conclusion
The papers featured in this special issue are a product of collaboration and mentoring relationships between early-career researchers and those established in HPSR, and the editorial team at HPP. The range of topics and contexts they cover demonstrates the value of diversity in research and scholarship.
The COVID-19 pandemic has further highlighted disparities in research output experienced by women (Malisch et al., 2020). This is in part due to the unintended consequences of public health measures implemented worldwide, leading to exacerbated disparities in gender roles and caregiving obligations, compounded by the lack of social support systems. Academic institutions, donors and journals all have a role to play in addressing these inequities and enriching global scholarship through creating more inclusive academic and research spaces.
