Impact of community health interventions on maternal and child health indicators in the upper east region of Ghana.

BACKGROUND: This paper reports on results of a health system strengthening implementation research initiative conducted the Upper East Region of northern Ghana. Transformative interventions to accelerate and strengthen the health delivery were implemented that included empowering community leaders and members to actively participate in health delivery, strengthening the referral systems through the provision of community transport systems, providing basic medical equipment to community clinics, and improving the skills of critical health staff through training. METHODS: A mixed method design was used to evaluate the impact of the interventions. A quantitative evaluation employed a flexible research design to test the effects of various component activities of the project. To assess impact, a pre-versus-post randomized cluster survey design was used. Qualitative research was conducted with focus group data and individual in depth interviews to gauge the views of various stakeholders associated with the implementation process. RESULTS: After intervention, significant improvements in key maternal and child health indicators such as antenatal and postnatal care coverage were observed and increases in the proportion of deliveries occurring in health facilities and assisted by skilled health personnel relative to pre-intervention conditions. There was also increased uptake of oral rehydration salts (ORS) for treatment of childhood diarrhoea, as well as marked reductions in the incidence of upper respiratory infections (URI). CONCLUSIONS: A pre-and post-evaluation of impact suggests that the programme had a strong positive impact on the functioning of primary health care. Findings are consistent with the proposition that the coverage and content of the Ghana Community-based Health Planning and Services programme was improved by program interventions and induced discernable changes in key indicators of health system performance.

Children born during the hunger season are at a higher risk of severe acute malnutrition: Findings from a Guinea Sahelian ecological zone in Northern Ghana.

Heightened food insecurity in the hunger season increases the risk of severe acute malnutrition (SAM) in childhood. This study examined the association of season of birth with SAM in a Guinean Sahelian ecological zone. We analyzed routine health and sociodemographic surveillance data from the Navrongo Health and Socio-demographic Surveillance System collected between 2011 and 2018. January-June, the period of highest food insecurity, was defined as the hunger season. We defined moderate acute malnutrition as child mid-upper arm circumference (MUAC) between 115 mm and 135 mm and SAM as MAUC ≤ 115 mm. We used adjusted logistic regression to quantify the association between the season of birth and SAM in children aged 6-35 months. From the 29,452 children studied, 24% had moderate acute malnutrition. Overall, 1.4% had SAM, with a higher prevalence (1.8%) in the hunger season of birth. Compared with those born October-December, adjusted odds ratios (aOR) and 95% confidence interval (95% CI) for SAM were increased for children born in the hunger season: January-March (1.77 [1.31-2.39]) and April-June (1.92 [1.44-2.56]). Low birth weight, age at an assessment of nutritional status, and ethno-linguistic group were also significantly associated with SAM in adjusted analyses. Our study established that being born in the hunger season is associated with a higher risk of severe acute malnutrition. The result implies improvement in the food supply to pregnant and lactating mothers through sustainable agriculture or food system change targeting the hunger season may reduce the burden of severe acute malnutrition.

The impact of indoor residual spraying on Plasmodium falciparum microsatellite variation in an area of high seasonal malaria transmission in Ghana, West Africa.

Here, we report the first population genetic study to examine the impact of indoor residual spraying (IRS) on Plasmodium falciparum in humans. This study was conducted in an area of high seasonal malaria transmission in Bongo District, Ghana. IRS was implemented during the dry season (November-May) in three consecutive years between 2013 and 2015 to reduce transmission and attempt to bottleneck the parasite population in humans towards lower diversity with greater linkage disequilibrium. The study was done against a background of widespread use of long-lasting insecticidal nets, typical for contemporary malaria control in West Africa. Microsatellite genotyping with 10 loci was used to construct 392 P. falciparum multilocus infection haplotypes collected from two age-stratified cross-sectional surveys at the end of the wet seasons pre- and post-IRS. Three-rounds of IRS, under operational conditions, led to a >90% reduction in transmission intensity and a 35.7% reduction in the P. falciparum prevalence (p < .001). Despite these declines, population genetic analysis of the infection haplotypes revealed no dramatic changes with only a slight, but significant increase in genetic diversity (He : pre-IRS = 0.79 vs. post-IRS = 0.81, p = .048). Reduced relatedness of the parasite population (p < .001) was observed post-IRS, probably due to decreased opportunities for outcrossing. Spatiotemporal genetic differentiation between the pre- and post-IRS surveys (D = 0.0329 [95% CI: 0.0209 - 0.0473], p = .034) was identified. These data provide a genetic explanation for the resilience of P. falciparum to short-term IRS programmes in high-transmission settings in sub-Saharan Africa.

Evaluation of pilot implementation of seasonal malaria chemoprevention on morbidity in young children in Northern Sahelian Ghana.

BACKGROUND: In Sahelian Africa, the risk of malaria increases with the arrival of the rains, particularly in young children. Following successful trials, the World Health Organization (WHO) recommended the use of seasonal malaria chemoprevention (SMC) in areas with seasonal peak in malaria cases. This study evaluated the pilot implementation of SMC in Northern Ghana. METHODS: Fourteen communities each serving as clusters were selected randomly from Lawra District of Upper West Region as intervention area and West Mamprusi District in the Northern Region as the non-intervention area. The intervention was undertaken by the National Malaria Control Programme in collaboration with regional health directorates using sulfadoxine-pyrimethamine plus amodiaquine and standard WHO protocols. Before and after surveys for malaria parasitaemia and haemoglobin levels as well as monitoring for malaria morbidity and mortality were undertaken. RESULTS: At the end of the intervention, participant retention was 92.9% (697/731) and 89.5% (634/708) in the intervention and the non-intervention areas, respectively. The proportion of children with asexual parasites reduced by 19% (p = 0.000) in the intervention and increased by 12% (p = 0.000) in the non-intervention area. Incidence rates of severe malaria were 10 and 20 per 1000 person-years follow up in the intervention and comparison areas, respectively with P.E of 45% (p = 0.62). For mild malaria, it was 220 and 170 per 1000 person-years in intervention and comparison area, respectively with PE of - 25% (p = 0.31). The proportion of children with anaemia defined as Hb< 11.0 g/dl reduced from 14.2% (52.8-38.6%) in the intervention area as compared to an increase of 8.1% (54.5% to 62.6) the non-intervention arm, Mean Hb reduced by 0. 24 g/dl (p = 0.000) in the non-intervention area and increased of 0.39 g/dl (p = 000) in the intervention area. CONCLUSIONS: The feasibility and effectiveness of SMC introduction in Northern Ghana was demonstrated as evidenced by high study retention, reduction in malaria parasitaemia and anaemia during the wet season.

Nasopharyngeal carriage of Streptococcus pneumoniae among healthy children in Kassena-Nankana districts of Northern Ghana.

BACKGROUND: Pneumococcal vaccine immunizations may be responsible for alterations in serotype epidemiology within a region. This study investigated the pneumococcal carriage prevalence and the impact of the 13-valent pneumococcal conjugate vaccine (PCV-13) on circulating serotypes among healthy children in Northern Ghana. METHODS: This was a cross sectional study conducted in the Kassena-Nankana districts of Northern Ghana from November to December during the dry season of 2018. Nasopharyngeal swabs collected from 193 participants were cultured per standard microbiological protocols and pneumococcal isolates were serotyped using the latex agglutination technique and the capsular Quellung reaction test. We examined for any association between the demographic characteristics of study participants and pneumococcal carriage using chi-square test and logistic regression. RESULTS: Of the 193 participants that were enrolled the mean age was 8.6 years and 54.4% were females. The carriage rate among the participants was 32.6% (63/193), and twenty different serotypes were identified. These included both vaccine serotypes (VT), 35% (7/20) and non-vaccine serotypes (NVT), 65% (13/20). The predominant serotypes (34 and 11A), both of which were NVT, accounted for a prevalence of 12.8%. PCV-13 covered only 35% of serotypes identified whiles 40% of serotypes are covered by PPV 23. CONCLUSION: Post-vaccination carriage of S. pneumoniae is high and is dominated by non-vaccine serotypes. There is therefore a need for the conduct of invasive pneumococcal disease surveillance (IPD) to find out if the high non-vaccine serotype carriage translates to disease. And in addition, a review of the currently used PCV-13 vaccine in the country would be considered relevant.

Supporting maternal and child nutrition: views from community members in rural Northern Ghana.

OBJECTIVE: Despite efforts to improve maternal and child nutrition, undernutrition remains a major public health challenge in Ghana. The current study explored community perceptions of undernutrition and context-specific interventions that could improve maternal and child nutrition in rural Northern Ghana. DESIGN: This exploratory qualitative study used ten focus group discussions to gather primary data. The discussions were recorded, transcribed and coded into themes using Nvivo 12 software to aid thematic analysis. SETTING: The study was conducted in rural Kassena-Nankana Districts of Northern Ghana. STUDY PARTICIPANTS: Thirty-three men and fifty-one women aged 18-50 years were randomly selected from the community. RESULTS: Most participants reported poverty, lack of irrigated agricultural land and poor harvests as the main barriers to optimal nutrition. To improve maternal and child nutrition, study participants suggested that the construction of dams at the community level would facilitate all year round farming including rearing of animals. Participants perceived that the provision of agricultural materials such as high yield seedlings, pesticides and fertiliser would help boost agricultural productivity. They also recommended community-based nutrition education by trained health volunteers, focused on types of locally produced foods and appropriate ways to prepare them to help improve maternal and child nutrition. CONCLUSION: Drawing on these findings and existing literature, we argue that supporting community initiated nutrition interventions such as improved irrigation for dry season farming, provision of agricultural inputs and community education could improve maternal and child nutrition.

Evolution of Antimalarial Drug Resistance Markers in the Reservoir of Plasmodium falciparum Infections in the Upper East Region of Ghana.

BACKGROUND: The majority of Plasmodium falciparum infections, constituting the reservoir in all ages, are asymptomatic in high-transmission settings in Africa. The role of this reservoir in the evolution and spread of drug resistance was explored. METHODS: Population genetic analyses of the key drug resistance-mediating polymorphisms were analyzed in a cross-sectional survey of asymptomatic P. falciparum infections across all ages in Bongo District, Ghana. RESULTS: Seven years after the policy change to artemisinin-based combination therapies in 2005, the pfcrt K76 and pfmdr1 N86 wild-type alleles have nearly reached fixation and have expanded via soft selective sweeps on multiple genetic backgrounds. By constructing the pfcrt-pfmdr1-pfdhfr-pfdhps multilocus haplotypes, we found that the alleles at these loci were in linkage equilibrium and that multidrug-resistant parasites have not expanded in this reservoir. For pfk13, 32 nonsynonymous mutations were identified; however, none were associated with artemisinin-based combination therapy resistance. CONCLUSIONS: The prevalence and selection of alleles/haplotypes by antimalarials were similar to that observed among clinical cases in Ghana, indicating that they do not represent 2 subpopulations with respect to these markers. Thus, the P. falciparum reservoir in all ages can contribute to the maintenance and spread of antimalarial resistance.

Machine learning approaches classify clinical malaria outcomes based on haematological parameters.

BACKGROUND: Malaria is still a major global health burden, with more than 3.2 billion people in 91 countries remaining at risk of the disease. Accurately distinguishing malaria from other diseases, especially uncomplicated malaria (UM) from non-malarial infections (nMI), remains a challenge. Furthermore, the success of rapid diagnostic tests (RDTs) is threatened by Pfhrp2/3 deletions and decreased sensitivity at low parasitaemia. Analysis of haematological indices can be used to support the identification of possible malaria cases for further diagnosis, especially in travellers returning from endemic areas. As a new application for precision medicine, we aimed to evaluate machine learning (ML) approaches that can accurately classify nMI, UM, and severe malaria (SM) using haematological parameters. METHODS: We obtained haematological data from 2,207 participants collected in Ghana: nMI (n = 978), SM (n = 526), and UM (n = 703). Six different ML approaches were tested, to select the best approach. An artificial neural network (ANN) with three hidden layers was used for multi-classification of UM, SM, and uMI. Binary classifiers were developed to further identify the parameters that can distinguish UM or SM from nMI. Local interpretable model-agnostic explanations (LIME) were used to explain the binary classifiers. RESULTS: The multi-classification model had greater than 85% training and testing accuracy to distinguish clinical malaria from nMI. To distinguish UM from nMI, our approach identified platelet counts, red blood cell (RBC) counts, lymphocyte counts, and percentages as the top classifiers of UM with 0.801 test accuracy (AUC = 0.866 and F1 score = 0.747). To distinguish SM from nMI, the classifier had a test accuracy of 0.96 (AUC = 0.983 and F1 score = 0.944) with mean platelet volume and mean cell volume being the unique classifiers of SM. Random forest was used to confirm the classifications, and it showed that platelet and RBC counts were the major classifiers of UM, regardless of possible confounders such as patient age and sampling location. CONCLUSION: The study provides proof of concept methods that classify UM and SM from nMI, showing that the ML approach is a feasible tool for clinical decision support. In the future, ML approaches could be incorporated into clinical decision-support algorithms for the diagnosis of acute febrile illness and monitoring response to acute SM treatment particularly in endemic settings.

Adapting a nurse-led primary care initiative to cardiovascular disease control in Ghana: a qualitative study.

BACKGROUND: Cardiovascular Disease (CVD) is a growing cause of morbidity and mortality in Ghana, where rural primary health care is provided mainly by the Community-based Health Planning and Services (CHPS) initiative. CHPS locates nurses in community-level clinics for basic curative and preventive health services and provides home and outreach services. But CHPS currently lacks capacity to screen for or treat CVD and its risk factors. METHODS: In two rural districts, we conducted in-depth interviews with 21 nurses and 10 nurse supervisors to identify factors constraining or facilitating CVD screening and treatment. Audio recordings were transcribed, coded for content, and analyzed for key themes. RESULTS: Respondents emphasized three themes: community demand for CVD care; community access to CVD care; and provider capacity to render CVD care. Nurses and supervisors noted that community members were often unaware of CVD, despite high reported prevalence of risk factors. Community members were unable to travel for care or afford treatment once diagnosed. Nurses lacked relevant training and medications for treating conditions such as hypertension. Respondents recognized the importance of CVD care, expressed interest in acquiring further training, and emphasized the need to improve ancillary support for primary care operations. CONCLUSIONS: CHPS staff expressed multiple constraints to CVD care, but also cited actions to address them: CVD-focused training, provision of essential equipment and pharmaceuticals, community education campaigns, and referral and outreach transportation equipment. Results attest to the need for trial of these interventions to assess their impact on CVD risk factors such as hypertension, depression, and alcohol abuse.

Prevalence and adverse obstetric outcomes of female genital mutilation among women in rural Northern Ghana.

BACKGROUND: Female genital mutilation (FGM) is commonly practiced in sub-Saharan Africa and results in adverse pregnancy outcomes among affected women. This paper assessed the prevalence and effects of FGM on pregnancy outcomes in a rural Ghanaian setting. METHODS: We analyzed 9306 delivery records between 2003 and 2013 from the Navrongo War Memorial Hospital. Multivariable logistic regression analyses were used to determine the effects of FGM on pregnancy outcomes such as stillbirth, birth weight, postpartum haemorrhage, caesarean and instrumental delivery. We also assessed differences in the duration of stay in the hospital by FGM status. RESULTS: A greater proportion of mothers with FGM (24.7%) were older than 35 years compared with those without FGM (7.6%). FGM declined progressively from 28.4% in 2003 to 0.6% in 2013. Mothers with FGM were nearly twice as likely to have caesarean delivery (adjusted odds ratios = 1.85 with 95%CI [1.72, 1.99]) and stillbirths (1.60 [1.21, 2.11]) compared with those without. Similarly, they had a 4-fold increased risk of post-partum haemorrhage (4.69 [3.74, 5.88]) and more than 2-fold risk lacerations/episiotomy (2.57 [1.86, 3.21]) during delivery. Average duration of stay in the hospital was higher for mothers with FGM from 2003 to 2007. CONCLUSIONS: Despite significant decline in prevalence of FGM, adverse obstetric outcomes are still high among affected women. Increased public health education of circumcised women on these outcomes would help improve institutional deliveries and heighten awareness and prompt clinical decisions among healthcare workers. Further scale-up of community level interventions are required to completely eliminate FGM.

Male involvement in maternal health: perspectives of opinion leaders.

BACKGROUND: Twenty years after acknowledging the importance of joint responsibilities and male participation in maternal health programs, most health care systems in low income countries continue to face challenges in involving men. We explored the reasons for men's resistance to the adoption of a more proactive role in pregnancy care and their enduring influence in the decision making process during emergencies. METHODS: Ten focus group discussions were held with opinion leaders (chiefs, elders, assemblymen, leaders of women groups) and 16 in-depth interviews were conducted with healthcare workers (District Directors of Health, Medical Assistants in-charge of health centres, and district Public Health Nurses and Midwives). The interviews and discussions were audio recorded, transcribed into English and imported into NVivo 10 for content analysis. RESULTS: As heads of the family, men control resources, consult soothsayers to determine the health seeking or treatment for pregnant women, and serve as the final authority on where and when pregnant women should seek medical care. Beyond that, they have no expectation of any further role during antenatal care and therefore find it unnecessary to attend clinics with their partners. There were conflicting views about whether men needed to provide any extra support to their pregnant partners within the home. Health workers generally agreed that men provided little or no support to their partners. Although health workers had facilitated the formation of father support groups, there was little evidence of any impact on antenatal support. CONCLUSIONS: In patriarchal settings, the role of men can be complex and social and cultural traditions may conflict with public health recommendations. Initiatives to promote male involvement should focus on young men and use chiefs and opinion leaders as advocates to re-orient men towards more proactive involvement in ensuring the health of their partners.

The risk of malaria in Ghanaian infants born to women managed in pregnancy with intermittent screening and treatment for malaria or intermittent preventive treatment with sulfadoxine/pyrimethamine.

BACKGROUND: Several studies have reported an association between malaria infection of the placenta and the risk of malaria in young children in the first year of life, but it is not known if this is causal, or influenced by malaria control measures during pregnancy. This paper compares the incidence of malaria in infants born to mothers who received either intermittent preventive treatment with sulfadoxine/pyrimethamine (IPTp-SP) or screening with a rapid diagnostic test and treatment with artemether-lumefantrine (ISTp-AL) during their pregnancy. METHODS: From July 2011 to April 2013, 988 infants of women enrolled in a trial of IPTp-SP versus ISTp-AL in the Kassena-Nankana districts of northern Ghana were followed to determine the risk of clinical malaria during early life, and their risk of parasitaemia and anaemia at 6 and 12 months of age. In addition, the incidence of clinical malaria in infants whose mothers had malaria infection of the placenta was compared with that in infants born to women free of placental malaria. RESULTS: The incidence of clinical malaria was 0.237 and 0.211 episodes per child year in infants whose mothers had received ISTp-AL or IPTp-SP, respectively. The adjusted incidence rate ratio and the adjusted rate difference were 0.94 (95% CI 0.68, 1.33) and 0.029 (95% CI -0.053, 0.110) cases per child year at risk respectively. The incidence of clinical malaria was similar in infants born to women with placental malaria (0.195 episodes per child year) and in infants of women without placental malaria (0.224 episodes per child year) (rate ratio = 0.86 [95% CI 0.54, 1.37]). CONCLUSION: Infants born to women managed with ISTp-AL during pregnancy were not at greatly increased risk of malaria compared with infants born to women who had received IPTp-SP. The incidence of malaria in infants was similar whether or not their mother had had placental malaria.

A qualitative analysis of the effect of a community-based primary health care programme on reproductive preferences and contraceptive use among the Kassena-Nankana of northern Ghana.

BACKGROUND: In 2000, Ghana launched the Community-based Health Planning and Services (CHPS) initiative to improve access to health and family planning services. This initiative was based in part on research, known as the Navrongo Project, conducted in the Kassena-Nankana district (KND) between 1994 to 2003 which demonstrated significant impact on fertility and child mortality. This paper examines current contraceptive perceptions in communities that were exposed to the Project's service models over the 1994 to 2003 period, and the post-experimental policies of the CHPS era. METHODS: Qualitative study was conducted in the KND of Ghana from June to September, 2012, by convening 8 male and 8 female FGD panels as well as 8 in-depth interviews of community leaders. Data collection was stratified by original experimental cell of the Navrongo Project to permit appraisal of social effects of contrasting experimental conditions. Inductive content analysis was performed with QSR Nvivo 10 to identify predominant themes. RESULTS: While findings show that exposure to community-based services was associated with enhanced approval of birth spacing and limitation, this view is grounded in perceptions that childhood survival has improved. Nonetheless, concerns were expressed about contraceptive side effects, prominently permanent sterility. Strategies for male outreach and community engagement originally introduced during the Navrongo Project have not been sustained with CHPS scale-up. The apparent atrophy of attention to the needs of men may explain the resistance of some males to the notion of female reproductive autonomy and the practice of some women to adopt contraception in secret. Despite this apparent programmatic dearth of male engagement, there is evidence to suggest that social impact of the original male engagement strategy persists in communities where male mobilization was combined with doorstep provision of family planning care during the Navrongo Project. CONCLUSION: Community-based services fostered attitudinal change towards family planning in a traditional sub-Saharan African setting. Sustained exposure to primary health care that have improved the survival of children has made the use of contraception more acceptable. Efforts should be embedded in primary health care programmes that address concerns about child survival while also consigning sustained priority to the information needs of men.

Evidence-based training and mentorship combined with enhanced outcomes surveillance to address the leading causes of neonatal mortality at the district hospital level in Ghana.

OBJECTIVE: To evaluate the impact of a district hospital intervention focused on enhancing healthcare provider capacity to address leading causes of neonatal death: birth asphyxia, infection and prematurity. METHODS: The neonatal quality improvement initiative was launched at two intervention referral district hospitals in Ghana. Local Health and Demographic Surveillance Systems were enlisted to enhance recording of neonatal and infant deaths in the community and at the facility. After baseline site assessments, a team of local paediatric experts conducted three clinical trainings on-site at each intervention hospital. Assessments were conducted to evaluate participant knowledge before and after participation in training modules. Monthly mentorship visits provided additional training to support the adoption of essential early neonatal care practices. RESULTS: In the first year of implementation, the initiative provided focused clinical training to 278 participants. A comparison of pre- and post-training test results demonstrates significant improvement in provider knowledge (73% vs. 89% correct, P < 0.001), with even greater improvement among trainees receiving recurrent refresher training (86% vs. 94% correct, P < 0.001). Participant feedback following training revealed enthusiasm about the programme and improved confidence. CONCLUSIONS: Locally led initiatives that invest directly in healthcare provider education and health systems strengthening represent a promising avenue for reducing neonatal morbidity and mortality. The NQI initiative demonstrates the positive impact of a district hospital intervention that combines on-site training, mentorship and enhanced demographic surveillance.

Efficacy and safety of a combination of azithromycin and chloroquine for the treatment of uncomplicated Plasmodium falciparum malaria in two multi-country randomised clinical trials in African adults.

BACKGROUND: Given increasing rates of resistance to existing therapy, new options for treatment and prophylaxis of malaria are needed. METHODS: Two randomised, comparative, non-inferiority studies were conducted in Africa, one double-blinded and one open-label. Adults with fever, a positive peripheral blood smear, and a positive rapid diagnostic test for Plasmodium falciparum were randomised in both studies to either azithromycin (AZ) 1,000 mg plus chloroquine (CQ) 600-mg base (AZCQ 1,000 mg) once daily for three days or mefloquine hydrochloride (MQ) 1,250 mg (split dose). In the first study, an additional regimen of AZ 500 mg plus CQ 600-mg base (AZCQ 500 mg) once daily for three days was included. All study participants were hospitalised until three consecutive daily blood smears were negative for asexual P. falciparum parasitaemia. Study participants were evaluated weekly for 42 days, with Day 28 polymerase chain reaction (PCR)-corrected parasitological clearance rate as primary endpoint. RESULTS: A total of 467 subjects were randomised in the two studies. At 28 days' follow-up, PCR-corrected parasitological clearance rates in the per protocol population in the first study were 101/103 (98%) with AZCQ 1,000 mg compared with 102/103 (99%) with MQ (95% confidence interval [CI]: -5.2, 3.3). The AZCQ 500-mg regimen was stopped during an interim study review (six [86%] clearance of seven evaluable; two lost to follow-up). In the second study, clearance rates were similar: AZCQ 1,000 mg 107/107 (100%) vs MQ 111/112 (99%; 95% CI: -1.8, 3.6). Among the participating countries, in vitro CQ resistance based on pfcrt mutation frequency in the baseline isolates across both studies ranged from 20.8% (Zambia) to 96.1% (Uganda). Serious adverse events (AEs; all causality) were observed more frequently with MQ compared with AZCQ (four vs one, respectively), though discontinuations for AEs were similar (four vs three, respectively). Common AEs in the AZ-containing arms included pruritus, vomiting, dizziness, and headache. CONCLUSIONS: Among adults with symptomatic uncomplicated falciparum malaria in Africa, the combination of AZ 1,000 mg and CQ 600-mg base once daily for three days resulted in Day 28 PCR-corrected parasitological clearance rates of ≥98% and was non-inferior to treatment with MQ. AZCQ was well tolerated. TRIAL REGISTRATION: ClinicalTrials.gov identifiers NCT00082576 and NCT00367653.

Socio-economic and demographic determinants of under-five mortality in rural northern Ghana.

BACKGROUND: In spite of global decline in under-five mortality, the goal of achieving MDG 4 still remains largely unattained in low and middle income countries as the year 2015 closes-in. To accelerate the pace of mortality decline, proven interventions with high impact need to be implemented to help achieve the goal of drastically reducing childhood mortality. This paper explores the association between socio-economic and demographic factors and under-five mortality in an impoverished region in rural northern Ghana. METHODS: We used survey data on 3975 women aged 15-49 who have ever given birth. First, chi-square test was used to test the association of social, economic and demographic characteristics of mothers with the experience of under-five death. Subsequently, we ran a logistic regression model to estimate the relative association of factors that influence childhood mortality after excluding variables that were not significant at the bivariate level. RESULTS: Factors that significantly predict under-five mortality included mothers' educational level, presence of co-wives, age and marital status. Mothers who have achieved primary or junior high school education were 45% less likely to experience under-five death than mothers with no formal education at all (OR = 0.55, p < 0.001). Monogamous women were 22% less likely to experience under-five deaths than mothers in polygamous marriages (OR = 0.78, p = 0.01). Similarly, mothers who were between the ages of 35 and 49 were about eleven times more likely to experience under-five deaths than those below the age of 20 years (OR = 11.44, p < 0.001). Also, women who were married had a 27% less likelihood (OR = 0.73, p = 0.01) of experiencing an under-five death than those who were single, divorced or widowed. CONCLUSION: Taken independently, maternal education, age, marital status and presence of co-wives are associated with childhood mortality. The relationship of these indicators with women's autonomy, health seeking behavior, and other factors that affect child survival merit further investigation so that interventions could be designed to foster reductions in child mortality by considering the needs and welfare of women including the need for female education, autonomy and socioeconomic well-being.

Early life ambient air pollution, household fuel use, and under-5 mortality in Ghana.

INTRODUCTION: Environmental exposures, such as ambient air pollution and household fuel use affect health and under-5 mortality (U5M) but there is a paucity of data in the Global South. This study examined early-life exposure to ambient particulate matter with a diameter of 2.5 µm or less (PM2.5), alongside household characteristics (including self-reported household fuel use), and their relationship with U5M in the Navrongo Health and Demographic Surveillance Site (HDSS) in northern Ghana. METHODS: We employed Satellite-based spatiotemporal models to estimate the annual average PM2.5 concentrations with the Navrongo HDSS area (1998 to 2016). Early-life exposure levels were determined by pollution estimates at birth year. Socio-demographic and household data, including cooking fuel, were gathered during routine surveillance. Cox proportional hazards models were applied to assess the link between early-life PM2.5 exposure and U5M, accounting for child, maternal, and household factors. FINDINGS: We retrospectively studied 48,352 children born between 2007 and 2017, with 1872 recorded deaths, primarily due to malaria, sepsis, and acute respiratory infection. Mean early-life PM2.5 was 39.3 µg/m3, and no significant association with U5M was observed. However, Children from households using "unclean" cooking fuels (wood, charcoal, dung, and agricultural waste) faced a 73 % higher risk of death compared to those using clean fuels (adjusted HR = 1.73; 95 % CI: 1.29, 2.33). Being born female or to mothers aged 20-34 years were linked to increased survival probabilities. INTERPRETATION: The use of "unclean" cooking fuel in the Navrongo HDSS was associated with under-5 mortality, highlighting the need to improve indoor air quality by introducing cleaner fuels.

Hypertension knowledge, attitudes and perceptions among adults in the Navrongo Health and Demographic Surveillance Site: a mixed methods analysis.

BACKGROUND: This study assessed knowledge, behaviors, and perceptions towards hypertension following community dissemination on cardiovascular disease (CVD) risk within the Navrongo Health and Demographic Surveillance Site in Northern Ghana. METHODS: A cross-sectional mixed methods study was conducted among middle aged men and women following education on CVD and their risk factors. Knowledge and attitudes of participants regarding hypertension were measured in 310 participants using a survey tool and the resultant data was analyzed with descriptive statistics. Focus group discussions (FDG) were used to assess perceptions of 40 study participants on their lived experiences with hypertension. Recorded interviews were transcribed verbatim and coded into themes using Nvivo 12 software before thematic analysis. RESULTS: Of the 310 surveyed participants, 54% were women and the mean age was 50 ± 6 years. The results showed that 84% of participants had heard about hypertension, 70% knew it was an increase in blood pressure and could be caused by excess salt intake, poor diet and physical inactivity. About 22.3% of participants were aware of the had hypertension. In terms of management, majority of the participants were aware that hypertension could be treated with antihypertensive medication and that untreated or uncontrolled hypertension could result in adverse health consequences. Few participants had ever had their blood pressure measured and did not access screening or healthcare care services and rather perceived the health system as inadequate to screen, and manage hypertension. CONCLUSION: Though, knowledge on hypertension was high, awareness of hypertension status and access to screening and healthcare services was low. Community beliefs and perceptions strongly influence treatment, and control of hypertension. Effective sustained community dissemination efforts addressing misperceptions could improve hypertension treatment and control.

Exploring infant and young child-feeding practices among mothers of well-nourished children in northern Ghana: An INPreP substudy.

This study investigated infant and young child-feeding (IYCF) practices among mothers of well-nourished children in northern Ghana. This was a qualitative study where in-depth individual interviews were conducted with participants. The interviews were audio recorded, transcribed, and QSR Nvivo software version 11 was used to organize the data before thematic analysis. It was observed that mothers of well-nourished children were likely to adhere to breastfeeding guidelines and also practice appropriate complementary feeding. Furthermore, these mothers mostly had some form of support from their husbands and mother-in-laws in feeding their infants. While adoption and adherence to appropriate IYCF practices contribute to improved nutrition outcomes in children, social support systems are needed to sustain the practice.

Seroepidemiological and parasitological evaluation of the heterogeneity of malaria infection in the Gambia.

BACKGROUND: As countries make progress in malaria control, transmission may be reduced to such an extent that few cases occur, and identification of the remaining foci of transmission may require a combination of surveillance tools. The study explored the usefulness of parasite prevalence, seroprevalence and model-estimated seroconversion rates for detecting local differences in malaria transmission in a West African country. METHODS: Age-stratified cross-sectional surveys were conducted during the wet season in 2008 and the following dry season in 2009 in The Gambia. In each season, 20 village communities were sampled from six diverse areas throughout the country. A total of 7,586 participants were surveyed, 51% (3,870) during the wet season. Parasites were detected by thick film slide microscopy, and anti-MSP1-19 antibodies were detected by ELISA using eluted dried blood from filter papers. RESULTS: Overall parasite prevalence was 12.4% in the wet season and 2.2% in the dry season, with village-specific parasite prevalence ranging from 1.4 to 45.9% in the wet season and from 0.0 to 13.2% in the dry season. Prevalence was highest in the eastern part of the country. Serological indices also varied between villages, indicating local heterogeneity in transmission, and there was a high correlation between wet and dry season estimates across the villages. The overall prevalence of anti-MSP119 antibodies was similar in the wet (19.5%) and in the dry (19.6%) seasons. CONCLUSION: The study illustrates the utility of measuring both parasite prevalence and serological indices for monitoring local variation in malaria transmission, which are more informative than single measures as control intensifies and malaria declines. Measurements of seropositivity have the logistical advantage of being relative stable seasonally so that sampling at any time of year may be conducted.
