RESUMEN
Long COVID (LC) occurs after at least 10% of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections, yet its etiology remains poorly understood. We used 'omic" assays and serology to deeply characterize the global and SARS-CoV-2-specific immunity in the blood of individuals with clear LC and non-LC clinical trajectories, 8 months postinfection. We found that LC individuals exhibited systemic inflammation and immune dysregulation. This was evidenced by global differences in T cell subset distribution implying ongoing immune responses, as well as by sex-specific perturbations in cytolytic subsets. LC individuals displayed increased frequencies of CD4+ T cells poised to migrate to inflamed tissues and exhausted SARS-CoV-2-specific CD8+ T cells, higher levels of SARS-CoV-2 antibodies and a mis-coordination between their SARS-CoV-2-specific T and B cell responses. Our analysis suggested an improper crosstalk between the cellular and humoral adaptive immunity in LC, which can lead to immune dysregulation, inflammation and clinical symptoms associated with this debilitating condition.

Climate change is having an adverse effect on the environment especially in sub-Sahara Africa, where capacity for natural resource management such as water is very low. The scope of the effect on land use types have to be estimated to inform proper remedy. A combined estimation of transpiration and evaporation from plants and soil is critical to determine annual water requirement for different land use. Evapotranspiration (ET) is a major component in the world hydrological cycle, and understanding its spatial dimensions is critical in evaluating the effects it has on regional land use. A measure of this component is challenging due to variation in rainfall and environmental changes. The mapping evapotranspiration with high resolution and internalized calibration (METRIC) method is employed to create evapotranspiration map for land use, using remotely sensed data by satellite, processed, and analyzed in ArcGIS. Normalized difference vegetation index (NDVI) was related to the availability of water for vegetation on different land use, and the results indicate a high evapotranspiration for vegetated land use with high NDVI than land use with low NDVI.

BACKGROUND: Sex composition of living children within the context of "sex preference" and its association with various reproductive health outcomes has been extensively studied in South and South East Asia. Although sex preference has been observed in sub-Saharan Africa, there is paucity of research on sex composition of living children and its association with reproductive health behaviours and outcomes, particularly in a matrilineal inheritance system. The purpose of the study was to explore the existence of sex preference in a matrilineal inheritance system. Specifically, the study sought to better understand the issues by examining the sex composition of living children and how it is associated with reproductive outcomes such as pregnancy intendedness and intention to use postpartum family planning among women in a matrilineal area of Ghana. METHODS: This was a cross sectional study conducted at four selected health facilities in the Mfantseman municipality of the Central Region of Ghana. Out of the 1914 pregnant women attending antenatal clinic selected using total enumeration, from 2nd January to 30th April 2012, 1091 with living children and complete socio-demographic data were recruited for this study. Descriptive, chi square and multivariate logistic regression analyses were conducted. RESULTS: The mean age of the 1091 respondents in this study was 28.2 ± 6.0 years with mean gestational age of 26.7 ± 6.6 weeks. Whilst 78% of the women had at least a son, 71% had at least a daughter, with those having only sons exceeding those with only daughters by 6.3%. Also, majority of the women with more sons than daughters did not intend their current pregnancies. These observations, coupled with a sex ratio of 109 males to 100 females, inferred the existence of son preference. The levels of unintended pregnancy and intention to use postpartum family planning were high (70% and 78% respectively). There was an association between sex composition of living children and unintended pregnancy but no association between sex composition of living children and intention to use postpartum family planning. Women with only sons were 50% less likely to have unintended pregnancies compared to those with equal number of sons and daughters [AOR 0.5, 95% CI (0.3-0.8)]. Similarly, women over 30 years were 80% less likely to have unintended pregnancies compared to those 15-19 years [AOR 0.2, 95% CI (0.1-0.6)]. The women with parity of 5 or more and resident in Anomabo were more likely to have unintended pregnancy compared to those with parity of up to two [AOR 3.8, 95% CI (1.7-8.59)] and those resident in Saltpond [AOR 1.8, 95%CI (1.1-2.8), respectively. In addition, the women resident in Anomabo were more likely to have intention to use postpartum family planning compared to those in Saltpond [AOR 1.8, 95% CI (1.0-3.3)]. CONCLUSION: There was persistence of more sons than daughters born in a predominantly matrilineal inheritance system and sex composition of living children had significant association with pregnancy intendedness but not with intention to use postpartum family planning.

BACKGROUND: Cervical cancer is a very common disease among women in Ghana and in the world as a whole. However, there is a dearth of information on the mechanisms cervical cancer patients adopt to cope with the condition in Ghana. This study sought to explore the strategies adopted by cervical cancer patients in rural Ghana to cope with the disease. METHODS: In-depth interviews were conducted to collect qualitative data from cervical cancer patients in a health facility in the Volta Region of Ghana. Data processing was done using the R software package for Qualitative Data Analysis (RQDA) and a thematic approach was used to analyse and present the results. RESULTS: The results show that cervical cancer patients adopted personal and psychological strategies such as sexual abstinence, personal hygiene, and disease denial to cope with the condition. Respondents also described social, financial and non-material support services they received from family members and the church as critical resources, which helped them to manage the conditions of the disease. Respondents also reported that faith healing, herbal and orthodox medicines helped them to manage the symptoms of the disease. CONCLUSIONS: Cervical cancer patients used a variety of coping strategies to manage the disease. Yet, it will be essential for interventions to focus on strengthening knowledge about the disease. This study underscores the need for financial, social and material support as well as an encouragement of the use of health services among cervical cancer patients.

Due to a number of biological, social, developmental, and behavioural factors young people are disproportionately affected by STIs including HIV and AIDS. Using the Health Belief Model, the study investigated factors influencing perception of risk of HIV among adolescents living in an urban slum in Ghana. Data were obtained from 902 adolescents, aged 10-19 years living in Kwesimintsim Zongo, an urban slum in the Western region of Ghana. A multi-staged sampling technique was used to select the respondents and both bivariate and multivariate analyses were carried out to examine the factors influencing perception of risk of HIV among adolescents. Adolescents' perception of risk of HIV was generally low and was predicted by age, ethnicity, membership of social groups and exposure to the print media. The low risk perception might cause adolescents to engage in behaviours, which are likely to endanger their health in general, and reproductive health in particular. Considering the effects of HIV and AIDS on young people, it is imperative to put in place campaigns that would help to increase their perceived risks of HIV. Factors that affect adolescents' perception of risks should be taken into consideration in designing HIV and AIDS campaigns to ensure positive behavioural change.
RESUMEN
This study uses three key anthropometric measures of nutritional status among children (stunting, wasting and underweight) to explore the dual effects of household composition and dependency on nutritional outcomes of under-five children in Ghana. The objective is to examine changes in household living arrangements of under-five children to explore the interaction of dependency and nucleation on child health outcomes. The concept of nucleation refers to the changing structure and composition of household living arrangements, from highly extended with its associated socioeconomic system of production and reproduction, social behaviour and values, towards single-family households - especially the nuclear family, containing a husband and wife and their children alone. A negative relationship between levels of dependency, as measured by the number of children in the household, and child health outcomes is premised on the grounds that high dependency depletes resources, both tangible and intangible, to the disadvantage of young children. Data were drawn from the last four rounds of the Ghana Demographic and Health Surveys (GDHSs), from 1993 to 2008, for the first objective - to explore changes in household composition. For the second objective, the study used data from the 2008 GDHS. The results show that, over time, households in Ghana have been changing towards nucleation. The main finding is that in households with the same number of dependent children, in nucleated households children under age 5 have better health outcomes compared with children under age 5 in non-nucleated households. The results also indicate that the effect of dependency on child health outcomes is mediated by household nucleation and wealth status and that, as such, high levels of dependency do not necessarily translate into negative health outcomes for children under age 5, based on anthropometric measures.

BACKGROUND: Unintended pregnancies may carry serious consequences for women and their families, including the possibility of unsafe abortion, delayed prenatal care, poor maternal mental health and poor child health outcomes. Although between 1993 and 2008, unintended births decreased from 42% to 37% in Ghana, the rate of decline is low, whilst levels are still very high. This raises the need to understand factors associated with unintended pregnancies, especially among women in rural settings where the rates and risks are highest to help improve maternal health. METHOD: We collected data from 1,914 pregnant women attending antenatal clinic between January 2012 and April 2012 in four health facilities in the Mfantseman Municipal of the Central Region of Ghana. We used bivariate and multivariate logistic regression analyses to explore how socio-demographic characteristics, past reproductive health experiences, partner characteristics and relations, awareness and past experience with contraceptives, influenced the status of women's current pregnancy (whether intended or unintended). RESULTS: The mean age of the 1,914 respondents in this study was 25.6 ± 6.5 years. Seventy percent (70%) said the pregnancies they were carrying were unintended. The odds of carrying unintended pregnancy among women with five or more children were higher than those with one to two children [AOR 6.06, 95% CI (3.24-11.38) versus AOR 1.48, 95% CI (1.14-1.93)]. Women with other marital arrangements showed significantly higher odds of carrying unintended pregnancy compared to those married by ordinance (Muslim or Christian wedding). Women not living with their partners exhibited increased odds of having unintended pregnancies compared to women who lived with their partners (AOR 1.72, 95% CI: 1.28 - 2.30). Awareness of traditional methods of family planning (withdrawal and rhythm) was associated with lower odds of having unintended pregnancy compared to non-awareness (AOR 0.66, 95% CI (0.49-0.89). CONCLUSIONS: In this study, important risk factors associated with unintended pregnancies were: parity, living arrangements with partner, marriage by ordinance and awareness of traditional, non-pharmacological contraceptive methods. Family planning interventions targeting different groups of women, especially during the postpartum period, would be essential to reduce rates of unintended pregnancies and promote positive health outcomes.

Adults constitute gatekeepers on adolescent sexual and reproductive health (ASRH). This qualitative paper discusses the views of adults on ASRH problems and challenges based on 60 in-depth interviews conducted among adults in Ghana in 2005. Adults were purposively selected based on their roles as parents, teachers, health care providers and community leaders. The major ASRH problems mentioned were teenage pregnancy and HIV/AIDS. The results indicated a number of challenges confronting ASRH promotion including resistance from parents, attitudes of adolescents, communication gap between adults and adolescents and attitudes of health care providers. Among health workers three broad categories were identified: those who were helpful, judgmental and dictators. Some adults supported services for young people while others did not. Some served as mediators and assisted to 'solve' ASRH problems, which occurred in their communities. It is argued that exploring the views of adults about their fears and concerns will contribute to the development of strategies and programmes which will help to improve ASRH.

Urbanization in Sub-Saharan Africa requires vast quantities of sand to meet infrastructural demands. In Accra, Ghana, sand mining occurs predominantly on farmlands at the city's periphery. We selected three study communities to assess the effects of sand mining on agriculture using interviews with local farmers and soil analyses of mined and unmined fields. The results underscore the profound repercussions of sand mining on farmers, characterized by substantial agricultural land loss, the destruction of food crops, and the absence of compensation payments or land reclamation. The study further reveals a significant decline in soil fertility of mined fields compared to unmined fields as evidenced by reduced levels of carbon (C, by 6.3 g kg-1) and macronutrients (nitrogen (N, by 0.6 g kg-1), phosphorus (P, 12.7 mg kg-1), potassium (K, 77 mg kg-1) and magnesium (Mg, 88 mg kg-1)), and an increase in soil compaction (bulk density by 0.13 g cm-3 and penetration resistance by 0.11 MPa). Soil texture and pH were altered and sodium (Na, by 16 mg kg-1) and soil moisture (by 4%) increased. On a communal level, sand mining adversely affected water availability, road infrastructure, and the health of residents. The study fills research gaps on the effects of sand mining on agricultural productivity, soil fertility and livelihoods, emphasizing the urgent need for effective regulation, law enforcement and collaboration as well as compensation and land reclamation mechanisms to limit the adverse impacts of sand mining on ecosystem services. Further, the use of more sustainable building materials should be fostered to reduce the demand for sand in Ghana.
RESUMEN
The mechanisms of postacute medical conditions and unexplained symptoms after SARS-CoV-2 infection [Long Covid (LC)] are incompletely understood. There is growing evidence that viral persistence, immune dysregulation, and T cell dysfunction may play major roles. We performed whole-body positron emission tomography imaging in a well-characterized cohort of 24 participants at time points ranging from 27 to 910 days after acute SARS-CoV-2 infection using the radiopharmaceutical agent [18F]F-AraG, a selective tracer that allows for anatomical quantitation of activated T lymphocytes. Tracer uptake in the postacute COVID-19 group, which included those with and without continuing symptoms, was higher compared with prepandemic controls in many regions, including the brain stem, spinal cord, bone marrow, nasopharyngeal and hilar lymphoid tissue, cardiopulmonary tissues, and gut wall. T cell activation in the spinal cord and gut wall was associated with the presence of LC symptoms. In addition, tracer uptake in lung tissue was higher in those with persistent pulmonary symptoms specifically. Increased T cell activation in these tissues was also observed in many individuals without LC. Given the high [18F]F-AraG uptake detected in the gut, we obtained colorectal tissue for in situ hybridization of SARS-CoV-2 RNA and immunohistochemical studies in a subset of five participants with LC symptoms. We identified intracellular SARS-CoV-2 single-stranded spike protein-encoding RNA in rectosigmoid lamina propria tissue in all five participants and double-stranded spike protein-encoding RNA in three participants up to 676 days after initial COVID-19, suggesting that tissue viral persistence could be associated with long-term immunologic perturbations.

BACKGROUND: Uptake of postpartum family planning (PPFP) remains low in sub-Saharan Africa and very little is known about how pregnant women arrive at their decisions to adopt PPFP. This information is needed to guide the development of interventions to promote PPFP. METHODS: We conducted a survey among pregnant women attending antenatal clinics in a rural district in Ghana. We used univariate and multivariate logistic regression analysis to explore how knowledge of various family planning (FP) methods, past experience with their use and the acceptability of PPFP to male partners and close relations influenced the intention of pregnant women to adopt PPFP. RESULTS: We interviewed 1914 pregnant women in four health facilities. About 84% considered PPFP acceptable, and 70% intended to adopt a method. The most preferred methods were injectables (31.5%), exclusive breastfeeding (16.7%), and oral contraceptive pills (14.8%). Women whose first choice of PPFP method were injectables were more likely to be women who had had past experience with its use (O.R = 2.07, 95% C.I. 1.50-2.87). Acceptability of PPFP by the pregnant woman (O.R. = 3.21, 1.64-6.26), perception of partner acceptability (O.R. = 3.20, 1.94-5.48), having had prior experience with the use of injectables (O.R. = 3.72, 2.61-5.30) were the strongest predictors of the intention to adopt PPFP. Conversely women who knew about the diaphragm (O.R. = 0.59, 0.38-0.93) and those who had past experience with IUD use (O.R. = 0.13, 0.05-0.38) were less likely to want to adopt PPFP. CONCLUSIONS: Acceptability of PPFP to the pregnant woman, male partner approval, and past experience with the use of injectables are important factors in the PPFP decisions of women in this population. Antenatal and early postnatal care need to be adapted to take these factors into consideration.

BACKGROUND: The WHO recommended the use of the RTS,S/AS01 malaria vaccine (RTS,S) based on a pilot evaluation in routine use in Ghana, Kenya, and Malawi. A longitudinal qualitative study was conducted to examine facilitators and barriers to uptake of a 4-dose RTS,S schedule. METHODS: A cohort of 198 caregivers of RTS,S-eligible children from communities where RTS,S was provided through the pilot were interviewed three times over a ≈22-month, 4-dose schedule. The interviews examined caregiver perceptions and behaviors. Children's vaccination history was obtained to determine dose uptake. RESULTS: 162 caregivers remained at round 3 (R3); vaccination history was available for 152/162 children. Despite early rumors/fears, the uptake of initial doses was high, driven by vaccine trust. Fears dissipated by R2, replaced with an enthusiasm for RTS,S as caregivers perceived its safety and less frequent and severe malaria. By R3, 98/152 children had received four doses; 34 three doses; 9 one or two doses; and 11 zero doses. The health system and information barriers were important across all under-dose cases. Fears about AEFIs/safety were important in zero-, one-, and two-dose cases. Competing life/livelihood demands and complacency were found in three-dose cases. Regardless of the doses received, caregivers had positive attitudes towards RTS,S by R3. CONCLUSIONS: Findings from our study will help countries newly introducing the vaccine to anticipate and preempt reasons for delayed acceptance and missed RTS,S doses.
RESUMEN
Long COVID (LC), a type of post-acute sequelae of SARS-CoV-2 infection (PASC), occurs after at least 10% of SARS-CoV-2 infections, yet its etiology remains poorly understood. Here, we used multiple "omics" assays (CyTOF, RNAseq/scRNAseq, Olink) and serology to deeply characterize both global and SARS-CoV-2-specific immunity from blood of individuals with clear LC and non-LC clinical trajectories, 8 months following infection and prior to receipt of any SARS-CoV-2 vaccine. Our analysis focused on deep phenotyping of T cells, which play important roles in immunity against SARS-CoV-2 yet may also contribute to COVID-19 pathogenesis. Our findings demonstrate that individuals with LC exhibit systemic inflammation and immune dysregulation. This is evidenced by global differences in T cell subset distribution in ways that imply ongoing immune responses, as well as by sex-specific perturbations in cytolytic subsets. Individuals with LC harbored increased frequencies of CD4+ T cells poised to migrate to inflamed tissues, and exhausted SARS-CoV-2-specific CD8+ T cells. They also harbored significantly higher levels of SARS-CoV-2 antibodies, and in contrast to non-LC individuals, exhibited a mis-coordination between their SARS-CoV-2-specific T and B cell responses. RNAseq/scRNAseq and Olink analyses similarly revealed immune dysregulatory mechanisms, along with non-immune associated perturbations, in individuals with LC. Collectively, our data suggest that proper crosstalk between the humoral and cellular arms of adaptive immunity has broken down in LC, and that this, perhaps in the context of persistent virus, leads to the immune dysregulation, inflammation, and clinical symptoms associated with this debilitating condition.
RESUMEN
The etiologic mechanisms of post-acute medical morbidities and unexplained symptoms (Long COVID) following SARS-CoV-2 infection are incompletely understood. There is growing evidence that viral persistence and immune dysregulation may play a major role. We performed whole-body positron emission tomography (PET) imaging in a cohort of 24 participants at time points ranging from 27 to 910 days following acute SARS-CoV-2 infection using a novel radiopharmaceutical agent, [18F]F-AraG, a highly selective tracer that allows for anatomical quantitation of activated T lymphocytes. Tracer uptake in the post-acute COVID group, which included those with and without Long COVID symptoms, was significantly higher compared to pre-pandemic controls in many anatomical regions, including the brain stem, spinal cord, bone marrow, nasopharyngeal and hilar lymphoid tissue, cardiopulmonary tissues, and gut wall. Although T cell activation tended to be higher in participants imaged closer to the time of the acute illness, tracer uptake was increased in participants imaged up to 2.5 years following SARS-CoV-2 infection. We observed that T cell activation in spinal cord and gut wall was associated with the presence of Long COVID symptoms. In addition, tracer uptake in lung tissue was higher in those with persistent pulmonary symptoms. Notably, increased T cell activation in these tissues was also observed in many individuals without Long COVID. Given the high [18F]F-AraG uptake detected in the gut, we obtained colorectal tissue for in situ hybridization SARS-CoV-2 RNA and immunohistochemical studies in a subset of participants with Long COVID symptoms. We identified cellular SARS-CoV-2 RNA in rectosigmoid lamina propria tissue in all these participants, ranging from 158 to 676 days following initial COVID-19 illness, suggesting that tissue viral persistence could be associated with long-term immunological perturbations.
RESUMEN
INTRODUCTION: Local health departments (LHDs) vary in their capacity to perform public health services by the size of population they serve. Little is known about the extent of emerging primary prevention activities at small LHDs. The objectives of this study were to describe various diabetes-related patient care and primary prevention services offered by small LHDs (those serving a population of less than 150,000) and explore factors associated with the diversity of these services. METHODS: During 2009 through 2010, we interviewed directors of a nationally representative sample of small LHDs by telephone to obtain information about staff structure, diabetes services, and partnerships. We obtained data for demographic characteristics and health status of the population from secondary sources. We analyzed the number of patient care services and primary prevention programs through multivariate regression analyses. RESULTS: Fifty-eight small LHDs completed the survey, a response rate of 81%. Most (n = 47) had at least 1 diabetes-related patient care service; referral to diabetes specialists was the most frequently identified service (n = 44). Nearly half of small LHDs also engaged in obesity prevention for adults (n = 26) or children (n = 26), but only 7 had a diabetes prevention program. Diversity of patient care services was positively associated with the proportion of the population that was rural, time commitment of a certified diabetes educator, and total staff size. Diversity of primary prevention programs was positively associated with intensity of collaboration with the state diabetes program and total staff size and inversely associated with the proportion of racial/ethnic minorities in the jurisdiction. CONCLUSION: Most small LHDs function as a link to local diabetes care services. Staff capacity, collaboration with the state health department, and local population factors appear to influence the diversity of diabetes-related services at small LHDs.

Unwanted sexual experiences are most frequently examined from the woman's perspective, yet these experiences happen to men as well. Part of the reason for the paucity of studies on coerced sexual experiences among men is the difficulty in gathering information about such experiences. This study examines the prevalence of unwanted sexual experiences at sexual debut as well as ever among young men aged 12-19 years old in Burkina Faso, Ghana, Malawi and Uganda. The data come from nationally-representative surveys and in-depth interviews with approximately 50 young men in each country gathered around 2004. Between 4 and 12% of young men stated that they were 'not willing at all' at sexual debut and between 3 and 6% said that they had ever experienced unwanted sex. Narratives from in-depth interviews give insights into the context surrounding men's unwanted sexual experiences. The sometimes conflicting information provided by the respondents serve to confound rather than illuminate the contexts within which these unwanted sexual experiences occurred, demonstrating that coercion for young men looks extremely different than coercion for young women, spurring us to improve our measures of sexual coercion among men.

Gold mining has played a significant role in Ghana's economy for centuries. Regulation of this industry has varied over time and while industrial mining is prevalent in the country, the expansion of artisanal mining, or Galamsey has escalated in recent years. Many of these artisanal mines are not only harmful to human health due to the use of Mercury (Hg) in the amalgamation process, but also leave a significant footprint on terrestrial ecosystems, degrading and destroying forested ecosystems in the region. In this study, the Landsat image archive available through Google Earth Engine was used to quantify the total footprint of vegetation loss due to artisanal gold mines in Ghana from 2005 to 2019 and understand how conversion of forested regions to mining has changed over a decadal period from 2007 to 2017. A combination of machine learning and change detection algorithms were used to calculate different land cover conversions and the timing of conversion annually. Within the study area of southwestern Ghana, our results indicate that approximately 47,000 ha (⨦2218 ha) of vegetation were converted to mining at an average rate of ~2600 ha yr-1. The results indicate that a high percentage (~50%) of this mining occurred between 2014 and 2017. Around 700 ha of this mining occurred within protected areas as mapped by the World Database of Protected Areas. In addition to deforestation, increased artisanal mining activity in recent years has the potential to affect human health, access to drinking water resources and food security. This work expands upon limited research into the spatial footprint of Galamsey in Ghana, complements mapping efforts by local geographers, and will support efforts by the government of Ghana to monitor deforestation caused by artisanal mining.
RESUMEN
BACKGROUND: This study sought to explore the barriers to the uptake of cervical cancer screening and treatment in the North Tongu district of Ghana. METHODS: Twenty-five in-depth interviews were conducted, while three focus group discussions were held among respondents. The data were analysed with the R package for qualitative data analysis using a thematic analytical approach. RESULTS: Low level of knowledge about the disease and screening services, personal or psychological convictions, and cost of screening and treatment coupled with a low level of income were the barriers at the individual level. Perceived health personnel attitude, perceived lack of privacy, and misdiagnosis were the barriers at the institutional level while the sociocultural belief system of the communities about the etiology of the disease was the barrier at the community level. Inadequate education about the disease, lack of funding and access to screening facilities also constrained screening and treatment at the policy level. CONCLUSIONS: Cervical cancer screening and treatment are constrained at multiple levels in rural Ghana. This study underscores the need to address the low uptake of cervical cancer screening and treatment at the individual, community, institutional, and policy levels simultaneously.

Men have a critical role to play in reducing cervical cancer burden. Yet, there is little information on male involvement in the cervical cancer screening and treatment process in Ghana. In this study, we explore male knowledge and support during cervical cancer screening and treatment in a rural setting in Ghana. In-depth interviews and focus group discussions were conducted among a total of 41 respondents to collect qualitative data from cervical cancer patients, their male partners and other married men in the North Tongu District, Ghana. A thematic approach was used for data analysis and presentation of the results. The results show that male partners have little or no knowledge about cervical cancer. Some men provide various forms of support-financial, social, material and emotional-to their partners during the screening and treatment stages of the disease. Some men, however, abandoned their partners during the screening and treatment process of the disease. Men whose partners did not have cervical cancer said they were willing to provide financial, social, emotional and material support to their partners if they should contract the disease. Some men said they were willing to support their female partners but lacked education on the disease. This study underscores the need for cervical cancer education programmes to target Ghanaian men. The education should focus on the causes of the disease, screening and treatment methods of the disease, and, ultimately, promote spousal support during the screening and treatment processes.

Associations between water sources, socio-demographic characteristics and household drinking water quality are described in a representative sample of six coastal districts of Ghana's Central Region. Thirty-six enumeration areas (EAs) were randomly chosen from a representative survey of 90 EAs in rural, semi-urban and urban residence strata. In each EA, 24 households were randomly chosen for water quality sampling and socio-demographic interview. Escherichia coli per 100 ml H2O was quantified using the IDEXX Colilert system and multi-stage regression models estimated cross-sectional associations between water sources, sanitation and socio-demographic factors. Almost three quarters, 74%, of the households have > 2 E. coli /100 ml H2O. Tap water has significantly lower E. coli levels compared with surface or rainwater and well water had the highest levels. Households with a water closet toilet have significantly lower E. coli compared with those using pit latrines or no toilets. Household size is positively associated, and a possessions index is negatively associated, with E. coli. Variations in community and household socio-demographic and behavioural factors are key determinants of drinking water quality. These factors should be included in planning health education associated with investments in water systems.
