To evaluate the performance of Ghana’s environmental surveillance (ES) system for poliovirus (PV) detection from 2018 to 2022 using standardised indicators developed by the WHO and the US Centers for Disease Control and Prevention.
A retrospective performance evaluation using 10 key indicators benchmarked against global targets for PV surveillance.
Seven regions across Ghana, participating in the national ES programme implemented under the Global Polio Eradication Initiative.
Wastewater sampling was conducted at designated ES sites, supported by field collection teams and laboratory personnel responsible for sample acquisition, processing and reporting of PV detection results.
Detection rates of PV and non-polio enteroviruses (NPEVs), timeliness of sample collection and reporting, data quality and system stability.
A total of 738 wastewater samples were collected. The system demonstrated high sensitivity, detecting circulating vaccine-derived PV type 2 in 51 (6.9%) of samples, Sabin PV types 1 and 3 in 61 (9.5%) and 114 (17.8%), respectively, and NPEVs in 491 (66.5%) of samples. Over 80% of samples met the recommended 21-day collection-to-reporting time frame. Data quality exceeded the ≥80% threshold, and workflows remained stable throughout the evaluation period.
Ghana’s ES system for PV was found to be flexible, stable and effective in generating high-quality data for early detection and public health response. These findings underscore the system’s critical role in supporting polio eradication efforts and highlight its potential as a model for surveillance in similar settings.
There is a global rise in the burden of childhood obesity, increasing the risk of early onset adult obesity. Most developing countries face the double burden of malnutrition; overnutrition as overweight/obesity and undernutrition.
To determine the current burden and determinants of childhood thinness, overweight and obesity using national survey data.
Data from a cross-sectional survey conducted in 2022 were used.
Data from the seventh Demographic Health Survey conducted in Ghana were used.
The participants included 4417 children ≤59 months.
The seventh Ghana Demographic Health Survey in 2022 employed a two-stage stratified cluster sampling design, selecting 618 clusters to create a nationally representative sample. Weight and height were measured using the SECA 874U scale and Shorrboard, respectively. Children’s heights were measured recumbent (24 months). Multivariate logistic regression was used to assess the relationship between thinness and obesity, as well as the independent factors.
The outcome variable was obesity, determined by a WHZ of >+2SD.
The weighted prevalence of overweight/obesity and thinness in children under 5 years is 9.9% and 5.2%, respectively. Children who were overweight or obese had a mean age of 23.11 months, those who were thin or severely thin had a lower mean age of 21.02 months, and those with normal nutritional status were relatively older, with a mean age of 28.41 months. The Upper West, Northeast and Northern regions had the lowest densities of obesity. In the multivariate logistic regression model, children residing in Ashanti, Oti, Northern, North East and Upper East regions had significantly reduced odds of being obese compared with those in the Ahafo region. The average haemoglobin for those overweight/obese was 10.8 g/dL, and 10.7 g/dL for those who were normal and marginally reduced, 10.5 g/dL for those who were thin.
Regional disparities, maternal nutritional status, socioeconomic conditions and unsafe water sources were significant determinants of child nutrition outcomes. These findings call for targeted, multipronged interventions that integrate maternal-child nutrition, safe water, sanitation and regional context.
This study aimed to examine the contextual barriers that may hinder the implementation of multiple family group therapy (MFGT) in Ghana’s Lower Manya Krobo District.
An exploratory, descriptive, qualitative study employing focus group discussions and in-depth interviews.
Atua Government Hospital in the Lower Manya Krobo District. Data were collected between February and March 2025.
12 young people living with HIV (YPLHIV; aged 12–22 years), 13 caregivers and five healthcare professionals were selected via purposive sampling.
Four major themes emerged: (1) resource and logistic constraints, including transportation challenges, programme sustainability concerns and inadequate physical facilities; (2) stigma and confidentiality concerns, encompassing public identification fears and community stigma; (3) implementation challenges, involving attendance reliability and organisational instability; and (4) participation barriers, including group setting anxiety and delayed HIV status disclosure. These barriers spanned multiple domains of the Consolidated Framework for Implementation Research (CFIR), highlighting the complex, multi-level nature of implementation challenges.
Successful implementation of MFGT for YPLHIV in Ghana requires addressing interrelated barriers across multiple ecological levels simultaneously. These findings largely underscore the importance of exploring the local context for potential barriers to inform the adaptation of evidence-based interventions to accommodate ecological concerns.
To evaluate how insurance influences the risk of a dementia diagnosis among a large, diverse cohort of US civilian adults with traumatic brain injury (TBI) over a 22-year period.
This is a retrospective cohort study involving individuals diagnosed with TBI.
The study used the Merative MarketScan Research Database, specifically drawing from the Commercial Claims and Encounters, Medicare Supplemental and Medicaid databases, from 2000 to 2022 in the USA. These databases provide comprehensive insights into healthcare services received by enrollees, including inpatient and outpatient services, outpatient prescription claims, clinical utilisation records and healthcare expenditures.
267 473 adults aged 55 and older who were diagnosed with a TBI between 1 January 2000 and 31 December 2022. Individuals with unknown TBI severity and dementia claims 2 years preceding TBI were excluded. TBI and dementia diagnoses were identified using International Classification of Disease 9th and 10th editions codes from inpatient and outpatient admission records.
None.
We compared the incidence of all-cause dementia across different insurance types to assess potential disparities in diagnosis following TBI. Cox proportional hazards models, with age as the time scale, were used to study the association between insurance type and dementia diagnosis following a TBI. Models were adjusted for key demographic variables, medical comorbidities and psychiatric conditions to account for potential confounding.
Of the 267 473 individuals with TBI, 12.7% were diagnosed with dementia over a mean follow-up period of 40 months (SD of 42 months). Dementia incidence differed significantly by insurance type, with 18.2% for Medicaid recipients, 17.3% for Medicare beneficiaries and only 2.3% among individuals with commercial insurance. The adjusted HR for dementia was notably higher among individuals enrolled on Medicaid (HR 2.9, 95% CI: 2.8 to 3.1) and Medicare (HR 2.1, 95% CI: 2.0 to 2.2), when compared with those with commercial insurance.
Individuals with TBI covered by Medicaid and Medicare are significantly more likely to be diagnosed with dementia, with a 2.9-fold and 2.1-fold increase risk, respectively, compared with those with commercial insurance. Addressing insurance-related disparities in dementia diagnosis is crucial for building a more equitable healthcare system. It is essential that individuals with TBI cases, regardless of their insurance type, have access to comprehensive care and preventive interventions to achieve the best possible long-term outcomes.
