  • Redesigning humanitarian health interventions

    Open AccessAugustus Osborne, Ahmed VandyARTICLEGlobal Public Health2026

    The current humanitarian health model frequently, though not universally, establishes temporary parallel systems that undermine local public health infrastructure through brain drain, bypassing local supply chains, and creating data silos, ultimately leaving systems vulnerable post-aid withdrawal. This tendency is most pronounced in sudden-onset disasters and high-visibility emergencies, yet even in protracted crises where humanitarian actors wor…

    BACKGROUND: The postpartum period is a critical window for addressing women's contraceptive needs.

This scoping review mapped the existing lit…

  • Utilizing longitudinal studies to address adolescent pregnancy in sub-Saharan Africa

    Open AccessAugustus Osborne, Bright Opoku AhinkorahARTICLEReproductive Health2026

    Adolescent pregnancy is a notable public health issue in sub-Saharan Africa. While nationally representative cross-sectional data such as the Demographic and Health Surveys (DHS) have offered valuable data to examine the burden of adolescent pregnancy, they do not fully capture the nature of this phenomenon. Longitudinal studies, by contrast, can provide insights into the factors influencing adolescent pregnancy, its impact, and the effectiveness…

    Tuberculosis (TB) remains a major global public health problem, with majority of the cases occurring in low- and middle-income countries (LMICs). Despite its growing burden, cross-country evidence on inequalities in financial burden among affected families is limited. This study aims to assess catastrophic costs and related inequalities across 19 LMICs. The study employed a cross-country analysis of 19 national TB Patient Cost Surveys data extrac…

This study analyses longitudinal trends in condom use, a key HIV prevention service and the associated socioeconomic inequalities among men in Sierra Leone to assess whether access and use are b…

  • Strengthening women’s leadership in health systems through innovation and intersectionality

    Open AccessAugustus Osborne, Morie VandiARTICLEInternational Journal for Equity…2026

    Women comprise most of the global health and care workforce, yet they remain underrepresented in leadership across health systems, including in ministries of health, hospitals, academic institutions, humanitarian agencies, and health financing bodies. This imbalance is not only a matter of fairness; it shapes whose expertise is recognised, which priorities are funded, and how health systems respond to inequity, crisis, and exclusion. The problem …

  • Inequalities in total fertility rate in Sierra Leone, 2008–2019

    Open AccessAugustus Osborne, Umaru Sesay et al.ARTICLEBMC Public Health2025

    The results indicate substantial socioeconomic and geographical disparities in total fertility rate among women in Sierra Leone that require targeted policy interventions. The persistent and widening economic gap between women in the richest and poorest quintiles suggests that poverty reduction strategies and economic empowerment programs for low-income women need strengthening. While the decreasing educational inequality is encouraging, the cont…

  • Bridging the gap

    Open AccessRegina Mamidy Yillah, Rajeeb Kumar Sah et al.ARTICLEBMC Public Health2025

    The findings underscore the need for safe, inclusive, and culturally sensitive comprehensive sexuality education in Sierra Leone.

  • Trends and inequalities of minimum dietary diversity among children aged 6–23 months in Sierra Leone, 2013–2019

    Open AccessAugustus Osborne, Camilla Bangura et al.ARTICLEBMC Public Health2025

    While the trend in minimum dietary diversity among children aged 6-23 months has shown an encouraging increase between 2013 and 2019, the proportion in 2019 indicates that further efforts are needed to improve minimum dietary diversity. Decreasing inequalities related to economic status, place of residence, and sex is promising, reflecting the country's progress toward achieving universal health coverage by 2030.
