RESUMO

Background: Childhood food insecurity can persist among low socioeconomic areas in high-income countries. Universal Free School Meal (UFSM) programs are designed to respond to this pressing issue. This study aimed to conduct a multi-year evaluation of the DIATROFI Program's impact on household food insecurity in Greece. Methods: This study utilized data from 18,716 students (618 kindergarten to high schools), from low socioeconomic areas participating in the school-level UFSM Program DIATROFI between 2012 and 2019. Parents of students completed annual baseline and follow-up paper-based self-completed questionnaires. The primary outcome was household food insecurity, measured using the Food Security Survey Module (FSSM) at both questionnaires, and evaluated through mixed linear and logistic regression models with repeated measurements. Findings: Students' median age was 9 years old (Interquartile range (IQR): 6.5, 12.0), 51.6% (n = 9658) were girls, and 82.2% (n = 15,382) lived in low/medium socioeconomic affluence households. Households with food insecurity reduced from 51.5% (n = 9630) to 47.6% (n = 8901) after one school year. Food insecurity score declined steadily for four years of consecutive participation, compared to baseline score (one-year b:-0.26; 95% Confidence Interval (CI):-0.30, -0.22, and four-year -1.28; -1.53, -1.03). The likelihood of retaining food insecure status reduced from 17% after one-year participation (Odds Ratio (OR): 0.83; 95% CI: 0.79, 0.87) to 36% after four-year participation (0.64; 0.49, 0.82). The Program's impact on household food insecurity alleviation was greater among households with low parental education and low socioeconomic affluence. Interpretation: The DIATROFI Program effectively improved household food security during and after the Greek socioeconomic crisis. School-level UFSM programs targeting underprivileged students can improve household food insecurity, with a more pronounced effect with increased years of participation, and among economically disadvantaged households. Funding: The DIATROFI Program was funded through various national and private organizations, including national prefecture authorities, Greek payment authorities, philanthropic/charitable organizations, and private companies.

RESUMO

OBJECTIVES: Online consultation scheduling is increasingly common in health services across various countries. This paper reviews articles published in the past five years and reflects on the risks and benefits of this practice, linking it to a recent Portuguese pilot project. METHODS: A search for articles from Web of Science and Scopus published since 2018 was conducted using the terms "online scheduling," "online booking," and "consultations." This search was completed in the last week of 2023. RESULTS: Out of 64 articles retrieved, 26 were relevant to the topic. These articles were reviewed, and their main findings, along with those from other relevant sources, were discussed. CONCLUSIONS: Several limitations of online consultations were identified, encompassing ethical, clinical, and economic aspects. While these consultations tend to be less expensive, their accessibility varies based on factors such as the users' age, whether they reside in rural or urban areas, and the technological capabilities of different countries, indicating that access disparities may continue to widen. Confidentiality concerns also arise, varying by medical specialty, along with issues related to payment. Overall, however, both users and health professionals view the advent of online consultation booking positively. In conclusion, despite the risks identified, online consultation booking has the potential to enhance user access to health services, provided that usage limitations and technological disparities are addressed. Research production has not kept pace with rapid technological advancements.

RESUMO

Introduction: Despite substantial investment in improving healthcare among adolescents in low- and middle-income countries, barriers to access and utilization of services persist, especially to sexual and reproductive health (SRH) services. In response to adolescents' health service needs due to their vulnerability, interventions aimed at improving access and utilization of sexual and reproductive health services have been implemented in specific regions of Zambia. To highlight progress in the access and the overall delivery of services in Zambia, in the wake of a system-level funding mechanism, this paper aims to understand the accessibility, availability, acceptability and quality (AAAQ) of health services provided to young people. Materials and methods: In a qualitative case study, 48 discussions- 32 individual interviews with stakeholders and 16 focus group discussions, consisting of 128 male and female adolescents were conducted in six districts from Eastern, Southern and Muchinga provinces of Zambia. Interviews were audio-recorded, recordings transcribed verbatim, and transcripts were analysed using deductive thematic analysis, using the AAAQ framework and Atun's framework on integration, as a guide to reporting the findings. Results: We found that adolescents knew of and had access to common commodities and services- male condoms, health education and HIV counselling and testing. However, availability was affected by access-related barriers such as frequent stock-outs and insufficiently trained healthcare providers. In addition, accessibility was more restricted during the COVID-19 pandemic lockdown and compounded by the low acceptability of SRH service among adolescents across all contexts. This led to the use of alternatives such as herbal medicine and maintained common myths and misconceptions. The overall quality was marred by the lack of dedicated spaces for adolescent health services and the lack of information, education and communication (IEC) materials in some spaces. Conclusion: While it was noted that some services were available for adolescents in all the study sites, numerous barriers inhibited access to these services and had an impact on the quality-of-service provision. With the added restriction to SRH service asses for young people, due to the low acceptability of adolescent SRH service use, the overall integration of adolescent SRH interventions into routine service provision was low and can be improved by targeting contextual barriers and maintaining best practices.

RESUMO

BACKGROUND: The Oncotype DX Genomic Prostate Score (ODX-GPS) is a gene expression assay that predicts disease aggressiveness. The objective of this study was to identify sociodemographic and regional factors associated with ODX-GPS uptake. METHODS: Data from Surveillance Epidemiology and End Results registries on men with localized prostate cancer with a Gleason score of 3 + 3 or 3 + 4, PSA ≤20 ng/mL, and stage T1c to T2c disease from 2013 through 2017 were linked with ODX-GPS data. Census-tract level neighborhood socioeconomic status (nSES) quintiles were constructed using a composite socioeconomic score. Multivariable logistic regression was used to estimate the associations of ODX-GPS uptake with age at diagnosis, race and ethnicity, nSES, geographic region, insurance type, and marital status, accounting for National Comprehensive Cancer Network risk group, year of diagnosis, and clustering by census tract. RESULTS: Among 111,434 eligible men, 5.5% had ODX-GPS test uptake. Of these, 78.3% were non-Hispanic White, 9.6% were Black, 6.7% were Hispanic, and 3.6% were Asian American. Black men had the lowest odds of ODX-GPS uptake (odds ratio, 0.70; 95% confidence interval [CI], 0.63-0.76). Those in the highest versus lowest quintile of nSES were 1.64 times more likely (95% CI, 1.38-2.94) to have ODX-GPS uptake. The odds of ODX-GPS uptake were statistically significantly higher among men residing in the Northeast, West, and Midwest compared to the South. CONCLUSIONS: Disparities in ODX-GPS uptake by race, ethnicity, nSES, and geographical region were identified. Concerted efforts should be made to ensure that this clinical test is equitably available.

RESUMO

BACKGROUND: People with developmental disabilities make important contributions to research. However, inaccessible research ethics trainings present a barrier to them taking on some research roles. OBJECTIVES: We developed a social-behavioral research ethics training that leads to certification tailored to the accessibility needs and roles of community research partners with developmental disabilities. METHODS: We collaborated with diverse partners (people with developmental disabilities, a disability service provider, health researchers, human research participant protections experts) to develop the research ethics training. To identify potential training content, we conducted a rapid scoping review of ethical, legal, and social issues in social-behavioral research with adults with developmental disabilities and reviewed national research ethics curricula. Through discussions and a modified Delphi process, we worked with partners to identify content to teach; partners also provided guidance on accessibility. RESULTS: The training and rapid scoping reviews and input from partners resulted in 93 potential educational content elements to include. After completing the modified Delphi process, partners recommended inclusion of 83 of these content elements in the educational training and provided input on depth and approach to teaching this content. Research Ethics for All is a freely available training that includes 5 units, delivered via didactic and active learning, and assessment activities to verify understanding. Research Ethics for All should be facilitated by an experienced researcher. CONCLUSIONS: Research Ethics for All includes foundational social-behavioral research ethics content designed to support community research partners with developmental disabilities to take on new research responsibilities.

RESUMO

BACKGROUND: Online food delivery services (OFDS) enable individuals to conveniently access foods from any deliverable location. The increased accessibility to foods may have implications on the consumption of healthful or unhealthful foods. Concerningly, previous research suggests that OFDS offer an abundance of energy-dense and nutrient-poor foods, which are heavily promoted through deals or discounts. OBJECTIVE: In this paper, we describe the development of the DIGIFOOD dashboard to monitor the digitalization of local food environments in New South Wales, Australia, resulting from the proliferation of OFDS. METHODS: Together with a team of data scientists, we designed a purpose-built dashboard using Microsoft Power BI. The development process involved three main stages: (1) data acquisition of food outlets via web scraping, (2) data cleaning and processing, and (3) visualization of food outlets on the dashboard. We also describe the categorization process of food outlets to characterize the healthfulness of local, online, and hybrid food environments. These categories included takeaway franchises, independent takeaways, independent restaurants and cafes, supermarkets or groceries, bakeries, alcohol retailers, convenience stores, and sandwich or salad shops. RESULTS: To date, the DIGIFOOD dashboard has mapped 36,967 unique local food outlets (locally accessible and scraped from Google Maps) and 16,158 unique online food outlets (accessible online and scraped from Uber Eats) across New South Wales, Australia. In 2023, the market-leading OFDS operated in 1061 unique suburbs or localities in New South Wales. The Sydney-Parramatta region, a major urban area in New South Wales accounting for 28 postcodes, recorded the highest number of online food outlets (n=4221). In contrast, the Far West and Orana region, a rural area in New South Wales with only 2 postcodes, recorded the lowest number of food outlets accessible online (n=7). Urban areas appeared to have the greatest increase in total food outlets accessible via online food delivery. In both local and online food environments, it was evident that independent restaurants and cafes comprised the largest proportion of food outlets at 47.2% (17,437/36,967) and 51.8% (8369/16,158), respectively. However, compared to local food environments, the online food environment has relatively more takeaway franchises (2734/16,158, 16.9% compared to 3273/36,967, 8.9%) and independent takeaway outlets (2416/16,158, 14.9% compared to 4026/36,967, 10.9%). CONCLUSIONS: The DIGIFOOD dashboard leverages the current rich data landscape to display and contrast the availability and healthfulness of food outlets that are locally accessible versus accessible online. The DIGIFOOD dashboard can be a useful monitoring tool for the evolving digital food environment at a regional scale and has the potential to be scaled up at a national level. Future iterations of the dashboard, including data from additional prominent OFDS, can be used by policy makers to identify high-priority areas with limited access to healthful foods both online and locally.

RESUMO

OBJECTIVE: This study examined patient and healthcare provider (HCP) perspectives on the impact of unmet social needs on healthcare barriers for patients with vasculitis. METHODS: Two surveys were developed to gather perspectives from patients with vasculitis, and HCPs specializing in vasculitis care. The patient survey also included a 20-question social needs assessment. The data were analyzed using descriptive statistics. RESULTS: One hundred patients and 31 HCPs completed the surveys between September 2022 and June 2023. Fifty-six percent of patients reported unmet social needs, with poor social and mental health (30%) being the most common. Sixty-three percent of patients with vasculitis perceived unmet social need(s) as barriers to healthcare access. Financial insecurity (30%), poor mental health (29%), and poor health knowledge (25%) were the most common barriers identified. Overall, HCPs perceived SDOH have a greater impact on healthcare access than the patients surveyed. Most patients (82%) and HCPs (90%) believed rheumatologists should help in the management of SDOH, specifically health knowledge and mental health. Few HCPs (10%) felt well-positioned to address patients' mental health. Suggested interventions that address social needs and improve healthcare access included referrals to community-based resources, providing educational materials, and virtual visits. CONCLUSION: Through patient and HCP perspectives, the impact of SDOH on healthcare access for patients with vasculitis was explored. Understanding the positive experiences and challenges faced by patients is crucial for developing targeted interventions to enhance healthcare access. These findings underscore the importance of ongoing efforts to improve the healthcare experience for patients with vasculitis. Key Points • The impact of unmet social needs on healthcare access for patients with vasculitis, illustrates the complex relationship between SDOH and healthcare outcomes. • Unmet social needs among patients with vasculitis, included poor social and mental health, financial and food insecurity, and a lack of health literacy, which may exacerbate challenges leading to poor health outcomes. • The differences in perspectives between patients and healthcare providers regarding the impact of certain SDOH on healthcare access, necessitates the importance of co-production in the development of interventions to improve healthcare delivery. • The importance of patient-centered care and tailored solutions was highlighted by the need for various interventions to address social needs and improve healthcare access, such as referrals to community-based resources, educational materials, and interprofessional collaboration.

RESUMO

Program development and evaluation that promote health equity are driven by community-based participatory research and led by people from select communities to adhere to the principles of diversity, equity, inclusion, and accessibility (DEIA). This process is enriched when these communities represent intersections within DEIA, such as, for example, Korean American women with depression. Research shows that culture-specific adaptations of services are significantly more effective for these communities than is the standard of care for the broader population. However, cultural specificity decreases generalizability of findings and scalability of interventions. Decisions about intersectionality are affected by implications for science as well as real-world benefits for individuals participating in this process.

RESUMO

We have developed a novel method for genomic footprinting of transcription factors (TFs) that detects potential gene regulatory relationships from DNase-seq data at the nucleotide level. We introduce an assay termed cross-link (XL)-DNase-seq, designed to capture chromatin interactions of dynamic TFs. A mild cross-linking step in XL-DNase-seq improves the detection of DNase-based footprints of dynamic TFs. The footprint strengths and detectability depend on an optimal cross-linking procedure. This method may help extract novel gene regulatory circuits involving previously undetectable TFs. The XL-DNase-seq method is illustrated here for activated mouse macrophage-like cells, which share several features with inflammatory macrophages.

RESUMO

BACKGROUND: China's family planning policies have experienced stages of one-child policy, partial two-child policy, and universal two-child policy. However, the impact of these policy shifts on the spatial accessibility to maternal and child health (MCH) services for women and children remains uncertain. This study aimed to evaluate the spatiotemporal trends and geographic disparities in spatial accessibility to MCH services in the context of two-child polices. METHODS: This study was conducted in Nanning prefecture, China, from 2013 to 2019. Data on the transportation networks, MCH institutes, the annual number of newborns, and the annual number of pregnant women in Nanning prefecture were collected. Gaussian two-step floating catchment area (Ga2SFCA) method was employed to measure the spatial accessibility to MCH services at county, township, and village levels. Temporal trends in spatial accessibility were analyzed using Joinpoint regression analysis. Geographic disparities in spatial accessibility were identified using geographic information system (GIS) mapping techniques. RESULTS: Overall, the spatial accessibility to MCH services showed an upward trend from 2013 to 2019 at county, town, and village levels, with the average annual percent change (AAPC) being 5.04, 4.73, and 5.39, respectively. Specifically, the spatial accessibility experienced a slight downward trend during the period of partial two-child policy for both parents only children (i.e., 2013-2014), a slight upward trend during the period of partial two-child policy for either parent only child (i.e., 2014-2016) and the early stages of universal two-child policy (i.e., 2016-2018), and a large upward trend in the later stages of universal two-child policy (i.e., 2018-2019). Spatial accessibility to MCH services gradually decreased from central urban areas to surrounding rural areas. Regions with low spatial accessibility were predominantly located in remote rural areas. CONCLUSION: With the gradual opening of the two-child policies, the spatial accessibility to MCH services for women and children has generally improved. However, significant geographic disparities have persisted throughout the stages of the two-child policies. Comprehensive measures should be considered to improve equity in MCH services for women and children.

RESUMO

BACKGROUND: Individuals with a history of cancer increasingly seek health information from online resources, including NCI-designated Cancer Center websites. Centers receive NCI designation because they provide excellent care and engage in cutting-edge research. However, the information presented on these webpages and their accessibility is unknown. An evaluation of the survivorship-focused webpages from NCI-designated Cancer Centers is needed to assess survivorship information and accessibility of these webpages. METHODS: We conducted an evaluation of the survivorship-focused webpages from 64 NCI-designated Cancer Centers. We evaluated where survivorship-focused webpages were housed, if there was a survivorship clinic or program, target audience of the webpage, how cancer survivor was defined, contact methods, and available resources. Accessibility outcomes included readability, font type, font size, color scheme, and alternative text (alt text) descriptors. An artificial intelligence (AI) audit was conducted to assess if the webpage was compliant with national accessibility guidelines. RESULTS: Most cancer centers had a survivorship-focused webpage, with 72% located on the cancer center's website and 28% on a health system website. Survivorship information available varied considerably and was often lacking in detail. Although three-quarters of webpages targeted patients only, variable definitions of cancer survivor were observed. Accessibility issues identified included inconsistent use of alt text descriptors, font size smaller than 15 points, and color schemes without adequate contrast. The average reading-level of information presented was above 12th grade. Only 9% of webpages were compliant with online accessibility guidelines; 72% semicompliant and 21% were noncompliant. CONCLUSIONS: Information presented on NCI-designated Cancer Center survivorship-focused webpages was inconsistent, often lacking, and inaccessible. NCI-designated Cancer Centers are role models for cancer research in the United States and have an obligation to provide survivorship information. Changes to content and website design are needed to provide better information for individuals seeking resources and health information relative to their cancer and care.

RESUMO

INTRODUCTION: The family plays a crucial role in shaping children's identity and understanding of gender-based roles. This study aims to explore the experiences of Iranian transgender individuals with their families' reactions to their transgender identity disclosure. METHODS: In 2018, nurse researchers conducted this qualitative study on 11 transgender individuals in Iran using a phenomenological approach, targeted and snowball sampling, and Colaizzi's seven-step method for data analysis. Rigor was ensured by adhering to Lincoln and Guba's standards. RESULTS: The study found varied reactions to transgender children among Iranian families, including abuse to avoid stigma. The study revealed two main themes, maladaptive and adaptive reactions, and identified six categories: denial of reality, mourning, coercion, deprivation, support out of necessity, and compromise of family reactions. DISCUSSION: Education and support systems may help address the cultural challenges that face families with transgender children. The findings offer insights for enhancing public awareness of the transgender community in conservative cultures.

RESUMO

Purpose: To evaluate the readability, accountability, accessibility, and source of online patient education materials for treatment of age-related macular degeneration (AMD) and to quantify public interest in Syfovre and geographic atrophy after US Food and Drug Administration (FDA) approval. Methods: Websites were classified into 4 categories by information source. Readability was assessed using 5 validated readability indices. Accountability was assessed using 4 benchmarks of the Journal of the American Medical Association (JAMA). Accessibility was evaluated using 3 established criteria. The Google Trends tool was used to evaluate temporal trends in public interest in "Syfovre" and "geographic atrophy" in the months after FDA approval. Results: Of 100 websites analyzed, 22% were written below the recommended sixth-grade reading level. The mean (±SD) grade level of analyzed articles was 9.76 ± 3.35. Websites averaged 1.40 ± 1.39 (of 4) JAMA accountability metrics. The majority of articles (67%) were from private practice/independent organizations. A significant increase in the public interest in the terms "Syfovre" and "geographic atrophy" after FDA approval was found with the Google Trends tool (P < .001). Conclusions: Patient education materials related to AMD treatment are often written at inappropriate reading levels and lack established accountability and accessibility metrics. Articles from national organizations ranked highest on accessibility metrics but were less visible on a Google search, suggesting the need for visibility-enhancing measures. Patient education materials related to the term "Syfovre" had the highest average reading level and low accountability, suggesting the need to modify resources to best address the needs of an increasingly curious public.

RESUMO

Background: Children with visual impairment and additional disabilities (VIAD) have difficulty accessing the visual information related to their parents' facial expressions and gestures. Similarly, it may be hard for parents to detect their children's subtle expressions. These challenges in accessibility may compromise emotional availability (EA) in parent-child interactions. The systematic use of the bodily-tactile modality for expressive and receptive communicative functions may function as a strategy to compensate for a child's lack of vision. This multiple-case study explored the effects of a bodily-tactile early intervention for three mothers and their one-year-old children with VIAD. Methods: Video data from baseline, intervention, and follow-up sessions were analyzed using a bodily-tactile coding procedure and EA Scales. Results: During the intervention, all mothers began to use a more bodily-tactile modality in early play routines and in different communicative functions. They increased their use of anticipatory cues, noticing responses, and tactile signs. Moreover, the children were more emotionally available to their mothers during the intervention and follow-up compared to the baseline. Conclusion: The results indicated that, during a short intervention, mothers could adopt a systematic use of the bodily-tactile modality in interactions with their children with VIAD. The results also suggest that, when mothers increased flexibility in communication channels, it was positively linked to their children's EA.

RESUMO

Physicians receive little dedicated training in caring for patients with disabilities. This study evaluated whether integrating disability-focused content into pre-clinical curricula improved medical student knowledge, readiness, and attitudes in caring for patients with disabilities. Readings, clinical reasoning cases, and patient panels were added to the existing pre-clinical curricula. Students self-reported increased knowledge and readiness in caring for patients with disabilities following implementation. No changes were reported in student attitudes toward patients with disabilities. Integrating disability-related training into the curricula was effective in improving students' self-reported knowledge and readiness to care for patients with disabilities. Supplementary Information: The online version contains supplementary material available at 10.1007/s40670-024-02061-5.

RESUMO

The Bacillus Calmette Guerin (BCG) vaccine has been shown to induce non-specific protection against diseases other than tuberculosis in vaccinated individuals, attributed to the induction of trained immunity. We have previously demonstrated that BCG administration induces innate immune training in mixed peripheral blood mononuclear cells and monocytes in calves. Gamma Delta (γδ) T cells are non-conventional T cells that exhibit innate and adaptive immune system features. They are in higher proportion in the peripheral blood of cattle than humans or rodents and play an essential role in bovine immune response to pathogens. In the current study, we determined if BCG administration induced innate immune training in bovine γδ T cells. A group of 16 pre-weaned Holstein calves (2-4 d age) were enrolled in the study and randomly assigned to vaccine and control groups (n=8/group). The vaccine group received two doses of 106 colony forming units (CFU) BCG Danish strain subcutaneously, separated by 2 weeks. The control group remained unvaccinated. Gamma delta T cells were purified from peripheral blood using magnetic cell sorting three weeks after receiving the 1st BCG dose. We observed functional changes in the γδ T cells from BCG-treated calves shown by increased IL-6 and TNF-α cytokine production in response to in vitro stimulation with Escherichia coli LPS and PAM3CSK4. ATAC-Seq analysis of 78,278 regions of open chromatin (peaks) revealed that γδ T cells from BCG-treated calves had an altered epigenetic status compared to cells from the control calves. Differentially accessible peaks (DAP) found near the promoters of innate immunity-related genes like Siglec14, Irf4, Ifna2, Lrrfip1, and Tnfrsf10d were 1 to 4-fold more accessible in cells from BCG-treated calves. MOTIF enrichment analysis of the sequences within DAPs, which explores transcription factor binding motifs (TFBM) upstream of regulatory elements, revealed TFBM for Eomes and IRF-5 were among the most enriched transcription factors. GO enrichment analysis of genes proximal to the DAPs showed enrichment of pathways such as regulation of IL-2 production, T-cell receptor signaling pathway, and other immune regulatory pathways. In conclusion, our study shows that subcutaneous BCG administration in pre-weaned calves can induce innate immune memory in the form of trained immunity in γδ T cells. This memory is associated with increased chromatin accessibility of innate immune response-related genes, thereby inducing a functional trained immune response evidenced by increased IL-6 and TNF-α cytokine production.

RESUMO

AIM: To evaluate the methodological quality of studies that analysed the relationship between accessibility to emergency services and infant mortality. METHODS: A systematic review with meta-analysis, registered on the international prospective register of systematic reviews (PROSPERO) platform under code CRD42021279854. Medline/Pubmed, Embase, SciElo, Lilacs, Scopus and web of science electronic databases were searched between November 2021 and May 2024, without language or publication time restriction. We included observational studies that compared the infant mortality outcome with the different distances travelled or travel time to health services in a paediatric emergency. Thus, we excluded studies with primary outcomes present in the pre- and perinatal periods, as well as distances or travel time to obstetric emergency units. We used the grade to assess the methodological quality of the studies and the Newcastle-Ottawa scale for the risk of bias, in addition to performing a meta-analysis. RESULTS: The evidence quality on infant mortality was moderate for four studies and low for three studies. The meta-analysis showed that children who travelled more than 5 km to the emergency service had a 28% increase in the chance of dying (P = 0.002), as well as those travelling for more than 40 min increased by 45% (P < 0.001). CONCLUSIONS: There was a relationship between the increase in geographic accessibility distance and travel time with the increase in infant mortality. However, the studies still showed moderate to low methodological quality.

RESUMO

OBJECTIVE: This meta-analysis aimed to estimate the national prevalence of postpartum depression (PPD) in Uganda and identify predictors in both pre-COVID-19 and post-COVID-19 eras. DESIGN: Used a systematic review and meta-analysis methodology. DATA SOURCES: Reviewed papers were sourced from Medline/PubMed, PsycINFO, CINAHL/EBSCOhost, Google Scholar, ScienceDirect and African Journals Online. ELIGIBILITY CRITERIA FOR SELECTED STUDIES: The review encompassed observational studies published on PPD in Uganda from 1 January 2000 to 30 November 2023. RESULTS: 11 studies (involving 7564 participants) published from 1 January 2000 to 30 November 2023 were reviewed. The pooled prevalence of PPD in Uganda was 29% (95% CI 21% to 37%, I2=98.32%). Subgroup analysis indicated a similar prevalence before (29%, 95% CI 20% to 39%) and during (28%, 95% CI 22% to 32%) the COVID-19 period. Special groups exhibited a higher prevalence (32%, 95% CI 16% to 47%) than general postpartum women (28%, 95% CI 19% to 37%). Factors associated with PPD included poor social support (OR 1.19, 95% CI 1.17 to 1.22, I2=96.8%), maternal illness (OR 1.22, 95% CI 1.19 to 1.26, I2=96.9%), poor socioeconomic status (OR 1.43, 95% CI 1.40 to 1.46, I2=99.5%) and undergoing caesarean section (OR 1.15, 95% CI 1.12 to 1.17, I2=80.6%). Surprisingly, there was a marginal decrease in PPD during the COVID-19 period. Subgroup analysis highlighted a higher prevalence among mothers with HIV. CONCLUSION: This study underscores the significant prevalence of PPD in Uganda, with sociodemographic factors increasing risk. Despite a slight decrease during the COVID-19 period, the importance of prioritising maternal mental health is emphasised, considering sociodemographic factors and pandemic challenges, to improve maternal and child health outcomes and overall well-being.
