    Background Majority of patients with cervical cancer in the low- and middle-income countries experience long diagnostic and pre-treatment intervals. This study sought to determine the factors associated with the diagnostic and pre-treatment intervals among patients with cervical cancer. Methods This was a cross-sectional study conducted at the Uganda Cancer Institute (UCI) during October 2019 to January 2020. Patients aged ≥ 18 years with histological diagnosis of cervical cancer were consecutively sampled. Data were collected using a pre-tested semi-structured questionnaire and a data abstraction form. Diagnostic intervals, defined as the time between first visit of a patient to a primary healthcare provider to time of getting confirmed diagnosis, of ≤ 3 months was defined as early & >3 months as late. Pre-treatment intervals, which is the time from histological diagnosis to starting cancer chemo-radiotherapy of ≤ 1 month was defined as early and > 1 month as late. Data were analysed using STATA version 14.0. We used modified Poisson regression models with robust variance to determine socio-demographic and clinical factors associated with the intervals. Results The mean age of the participants was 50.0 ± 11.7 years. The median diagnostic and pre-treatment intervals were 3.1 (IQR: 1.4–8.2) months and 2.4 (IQR: 1.2–4.1) months respectively. Half of the participants, 49.6% (200/403) were diagnosed early; one in 5 patients, 20.1% (81/403) promptly (within one month) initiated cancer chemo radiotherapy. Participants more likely to be diagnosed early included those referred from district hospitals (level 5) (aPR = 2.29; 95%CI: 1.60–3.26) and with squamous cell carcinomas (aPR = 1.55; 95%CI: 1.07–2.23). Participants more likely to be diagnosed late included those who first discussed their symptoms with relatives, (aPR = 0.77; 95%CI: (0.60–0.98), had > 2 pre-referral visits (aPR = 0.75; 95%CI (0.61–0.92), and had advanced stage (stages 3 or 4) (aPR = 0.68; 95%CI: 0.55–0.85). Participants more likely to initiate cancer chemo-radiotherapy early included older patients (≥ 60 years) (aPR = 2.44; 95%CI: 1.18–5.03). Patients likely to start treatment late were those who had ≥2 pre-referral visits (aPR = 0.63; 95%CI: 0.41–0.98) and those that took 3 - 6 months with symptoms before seeking healthcare (aPR = 0.52;95%CI: 0.29 - 0.95). Conclusion Interventions to promote prompt health-seeking and early diagnosis of cervical cancer need to target primary healthcare facilities and aim to enhance capacity of primary healthcare professionals to promptly initiate diagnostic investigations. Patients aged < 60 years require targeted interventions to promote prompt initiation of chemo-radiation therapy.

    Background Cervical cancer screening program in Uganda is opportunistic and focuses mainly on women aged 25–49 years. Female sex workers (FSWs) are at increased risk of developing invasive cervical cancer. There is limited data regarding the uptake and acceptability of cervical cancer screening among FSWs in Uganda. This study aimed at identifying factors associated with uptake and acceptability of cervical cancer screening among FSWs in Eastern Uganda. Methods This was a cross-sectional study conducted among 423 FSWs aged 18–49 years attending care at six health facilities serving Key Populations (FSWs, Men who have sex with men, transgender people, people who inject drugs and people in prisons) in the Teso sub-region. Data was collected using structured investigator administered questionnaire and analyzed using Stata statistical software version 15.0 (Stata Corp, Texas, USA). The primary outcome was uptake of cervical cancer screening measured as the proportion of female sex workers who have ever been screened for cervical cancer. Chi-square test was used to compare the differences in uptake of cervical cancer screening by HIV status. Modified Poisson regres sion model with a robust variance estimator was used to determine association between the outcome variables and selected independent variables including demographic charac teristics. Prevalence ratios (PR) with accompanying 95% confidence intervals have been reported. Statistical significance was considered at two-sided p-values ≤ 0.05. Results The mean age of the participants was 28.1 (±SD = 6.6) years. The self-reported HIV prevalence was 21.5% (n = 91). There were 138 (32.6%) participants who had ever been screened for cervical cancer (uptake), while 397 (93.9%) were willing to be screened (acceptability). There was a significant difference in cervical cancer screening uptake between women living with HIV (WLHIV) and those who were HIV negative, 59.3% vs 26.9% respectively (P < 0.001). The significant factors associated with uptake of cervical cancer screening included living with HIV, adjusted prevalence ratio (aPR) = 1.53 (95%CI: 1.15–2.07), increasing number of biological children, aPR = 1.14 (1.06–1.24) living near a private not for profit (PNFP) facility, aPR = 2.84 (95% CI; 1.68–4.80) and availability of screening services at the nearest health facility, aPR = 1.83 (95% CI, 1.30–2.57). Factors significantly associated with acceptability of cervical cancer screening included being 40 years or older, aPR = 1.22 (95%CI: 1.01–1.47), having a family history of cervical cancer, aPR = 1.05 (1.01–1.10), and living near a PNFP facility, aPR = 1.17 (95% CI, 1.09–1.27) and having ever screened before, aPR = 0.92 (0.86–0.98). Conclusion Female sex workers living with HIV are more likely to screen for cervical cancer than the HIV negative clients. Cervical cancer screening uptake is relatively low among the female sex workers. However, majority of the FSWs are willing to be screened for cervical cancer if the services are provided in the nearby healthcare facilities. There is need to make cer vical cancer screening services available to all eligible women especially the female sex workers and integrate the services with sexual reproductive health services in general and not just HIV/ART clinics services

    Profiling the disease burden in Teso subregion during community-based medical education and research services at Soroti University: a prospective study protocol
    (Archives of Public Health, 2026-06-18) Opito Ronald; Amos Odiit; Hellen Akurut; Emmanuel Ayikobua Tiyo; Joash Okoboi; Letizia Maria Atim; Clement Munguiko; Lawrence Obado; Bonniface Oryokot; Fred Kirya; Ruth Muhindo; David Aderu; Patrick Lubogo; Stephen Econyu; Simon Icumar Omeke; Samuel Kabwigu; Amos Deogratius Mwaka
    Background: Community-based medical education and research services (COBMERS) place medical students in primary health care facilities to strengthen their skills in community health service delivery, teamwork, leadership and professional ethics within limited-resource settings. Beyond training, COBMERS enables universities to generate evidence on local disease epidemiology, transmission dynamics, and control practices, resulting in a tangible, contextualized impact on the communities. There is however limited data on disease profile in Teso subregion, with limited epidemiological research in the area. This prospective study aims to profile the disease burden in the Teso subregion through COBMERS, thereby informing community-level interventions and health policy. Methods: The study will employ convergent parallel mixed-methods design, integrating quantitative and qualitative approaches. Quantitative ARTICLE IN PRESS components will include cross-sectional surveys to determine prevalence of non-communicable diseases (NCDs), neglected tropical diseases (NTDs), and ACCEPTED MANUSCRIPT ARTICLE IN PRESS infectious diseases, complemented by prospective cohort studies to assess temporal trends. Qualitative data will be gathered through focus group discussions and key informant interviews to explore community perceptions, health system capacity, and effectiveness of preventive measures. A community-based participatory research (CBPR) approach will guide all phases, ensuring that research is co-designed with community members, health practitioners, and local authorities. Medical students, under the supervision of faculty and site mentors, will serve as primary data collectors, integrating research with their COBMERS training. Discussion: The study is expected to provide evidence on the prevalence, trends, and risk factors of major diseases in the Teso subregion, alongside community perspectives on health priorities and barriers to care. Findings will stir up debates to inform tailored interventions, strengthen primary health care, and guide policy formulation. Additionally, embedding research within COBMERS is expected to build local research capacity among site mentors and students, fostering sustainability and continued community university collaboration. This protocol therefore provides an integrated framework that combines epidemiological surveillance, community engagement, and capacity building. By leveraging COBMERS and CBPR, the study seeks to provide actionable evidence to reduce the burden of NCDs, infectious diseases, and NTDs while promoting health system resilience in ARTICLE IN PRESS Eastern Uganda.
