Purpose This study aims to determine the pedagogical and socio-emotional impacts of school closures caused by the COVID-19 pandemic in Guinea.
Design/methodology/approach A descriptive, survey-based methodology was used to collect quantitative and qualitative data directly from parents and caregivers. Between February 24 and March 13, 2022, data was gathered from a study population comprising 2,955 adults residing in five communes and five prefectures of Guinea.
Findings Half of all respondents stated that school closures had no particular impact on children in their household, and 42% stated that no intentional pedagogical activities took place during school closures. Approximately 15% of respondents stated that children experienced boredom, loneliness, sadness, depression, stress and anxiety during the school closures.
Originality/value The study underscores the significance of school closure readiness and interactive learning while revealing limited emotional impact on children. The findings, while specific to Guinea, provide a foundational understanding, highlighting the complexity of pandemic effects on education and the need for adaptive strategies in vulnerable regions.
BACKGROUND: The death of children under-five years is one of the critical issues in public health and improving child survival continues to be a matter of urgent concern. In this paper, we assessed the proximate and socio-economics determinants of child mortality in Guinea. METHODS: Using the 2018 Guinea Demographic and Health Survey (GDHS), we extracted demographic and mortality data of 4,400 children under-five years. Both descriptive and multivariable logistic regression analyses were conducted. RESULTS: Under-five mortality was 111 deaths per 1,000 live births in Guinea. The likelihood of death was higher among children born to mothers who belong to other religions compared to Christians (aOR = 2.86, 95% CI: 1.10-7.41), smaller than average children compared to larger than average children (aOR = 1.97, 95% CI: 1.28-3.04) and those whose mothers had no postnatal check-up visits after delivery (aOR = 1.72, 95% CI: 1.13-2.63). Conversely, the odds of death in children with 2-3 birth rank & >2 years of birth interval compared to ≥4 birth rank and ≤2 years of birth interval were low (aOR = 0.53, 95% CI: 0.34-0.83). CONCLUSION: We found that household/individual-level socioeconomic and proximate factors predict under-five mortality in Guinea. With just about a decade left to the 2030 deadline of the Sustainable Development Goals (SDGs), concerted efforts across all key stakeholders, including government and development partners, need to be geared towards implementing interventions that target these predictors.

AbstractUtilization of antenatal care (ANC) services, as part of reproductive health care, presents a lifesaving chance for health promotion and the early diagnosis and treatment of illnesses throughout pregnancy. This study examines the factors associated with the number and timing of ANC visits among married women in Cameroon using data from the 2018 Cameroon Demographic and Health Survey. The outcome variables were number of ANC visits, categorized as <8 visits or ≥8 visits, and the timing of first ANC visit, categorized as ≤3 months (early) or >3 months (late) (as per the new 2016 WHO recommendations). Descriptive statistics and binary logistic regression were used to analyse the data. Crude odds ratios (cOR) and adjusted odds ratios (aOR) and p-values with significance at <0.05 were used to interpret the results. The proportions of women who had ≥8 ANC visits and first ANC visit at ≤3 months gestation were 6.3% and 35.6% respectively. Women aged 35–39 at childbirth (aOR=3.99, 95% CI=1.30–12.23), middle wealth quintile women (aOR=3.22, 95% CI=1.01–10.27), women whose husbands had secondary (aOR=7.00, 95% CI=2.26–21.71) or higher (aOR=16.93, 95% CI=4.91–58.34) education were more likely to have ≥8 ANC visits. Early timing of first ANC visit was low among women with birth order 3–4 (aOR=0.63, 95% CI=0.46–0.85). Conversely, the likelihood of having early ANC visits was high among women whose pregnancies were intended (aOR=1.32, 95% CI=1.01–1.74), the richest women (aOR=3.89, 95% CI=2.30–6.57) and women whose husbands had secondary (aOR=2.41, 95% CI=1.70–3.64) or higher (aOR=3.12, 95% CI=2.40–7.46) education. The study highlights that age at childbirth, wealth, husband's educational attainment, birth order and pregnancy intention could influence the utilization of ANC services among married women in Cameroon. Hence, to improve attendance and early initiation of ANC, interventions should be targeted at empowering women financially and removing all financial barriers associated with accessing ANC, improving ANC education among women and encouraging male involvement in ANC education.
AbstractThere is increasing evidence that women with the ability to exercise control over their sexual and reproductive lives have greater access to prompt prevention and treatment of maternal health disorders, resulting in a concomitant reduction in maternal morbidity and mortality. This study assessed the association between indices of women's empowerment and utilization of skilled antenatal, intrapartum and postnatal maternity care in two rural Local Government Areas in Edo State, Nigeria. Data were taken from a household survey conducted in July and August 2017, and the study sample comprised 1245 ever-married women currently in a union who had given birth in the 5 years preceding the survey. A Gender Roles Framework guided the selection of independent women's empowerment variables. Using hierarchical logistic regression, the likelihood of receiving all three levels of skilled maternal health care service (antenatal, intrapartum and postnatal) by women's empowerment variables, grouped into resource, decision-making and influencer domains following the model of Anderson and Neuman, was assessed. Of the resource domain variables, respondent's education and respondent's participation in payment for their own health care positively predicted their use of all three levels of skilled maternal care, whereas their ownership of land negatively predicted this. Two decision-making domain variables were significantly associated with respondent's use of all three levels of service: those who made decisions alone about major household purchases were twice as likely to use all three levels of services than when decisions were made by their partners or others, while respondent making decisions alone about what food to cook each day was a negative predictor. Of the influencer variables, religion and a large spousal education gap were strong positive factors, whereas living in a consensual union rather than being legally married was a negative factor. Although health system factors are important, interventions geared towards changing gender norms that constrain women's empowerment are critical to achieving maternal health-related development goals in Nigeria. A composite strategy that targets all women's empowerment indices is recommended, as Nigeria strives towards achieving SDG-3.
OBJECTIVE: The objective of this study was to determine the effectiveness of a set of multifaceted interventions designed to increase the access of rural women to antenatal, intrapartum, postpartum and childhood immunisation services offered in primary healthcare facilities. DESIGN: The study was a separate sample pretest–post-test quasi-experimental research. SETTING: The research was conducted in 20 communities and primary health centres in Esan South East and Etsako East Local Government Areas in Edo State in southern Nigeria PARTICIPANTS: Randomly selected sample of ever married women aged 15–45 years. INTERVENTIONS: Seven community-led interventions implemented over 27 months, consisting of a community health fund, engagement of transport owners on emergency transport of pregnant women to primary health centres with the use of rapid short message service (SMS), drug revolving fund, community education, advocacy, retraining of health workers and provision of basic equipment. PRIMARY AND SECONDARY OUTCOME MEASURES: The outcome measures included the number of women who used the primary health centres for skilled pregnancy care and immunisation of children aged 0–23 months. RESULTS: After adjusting for clustering and confounding variables, the odds of using the project primary healthcare centres for the four outcomes were significantly higher at endline compared with baseline: antenatal care (OR 3.87, CI 2.84 to 5.26 p<0.001), delivery care (OR 3.88, CI 2.86 to 5.26), postnatal care (OR 3.66, CI 2.58 to 5.18) and childhood immunisation (OR 2.87, CI 1.90 to 4.33). However, a few women still reported that the cost of services and gender-related issues were reasons for non-use after the intervention. CONCLUSION: We conclude that community-led interventions that address the specific concerns of women related to the bottlenecks they experience in accessing care in primary health centres are effective in increasing demand for skilled pregnancy and childcare in rural Nigeria.
Background: Owing to the severe repercussions associated with female genital mutilation (FGM) and its illicit status in many countries, the WHO, human rights organisations and governments of most sub-Saharan African countries have garnered concerted efforts to end the practice. This study examined the socioeconomic and demographic factors associated with FGM among women and their daughters in sub-Saharan Africa (SSA). Methods: We used pooled data from current Demographic and Health Surveys (DHS) conducted between January 1, 2010 and December 31, 2018 in 12 countries in SSA. In this study, two different samples were considered. The first sample was made up of women aged 15–49 who responded to questions on whether they had undergone FGM. The second sample was made up of women aged 15–49 who had at least one daughter and responded to questions on whether their daughter(s) had undergone FGM. Both bivariate and multivariable analyses were performed using STATA version 13.0. Results: The results showed that FGM among women and their daughters are significantly associated with household wealth index, with women in the richest wealth quintile (AOR, 0.51 CI 0.48–0.55) and their daughters (AOR, 0.64 CI 0.59–0.70) less likely to undergo FGM compared to those in the poorest wealth quintile. Across education, the odds of women and their daughters undergoing FGM decreased with increasing level of education as women with higher level of education had the lowest propensity of undergoing FGM (AOR, 0.62 CI 0.57–0.68) as well as their daughters (AOR, 0.32 CI 0.24–0.38). FGM among women and their daughters increased with age, with women aged 45–49 (AOR = 1.85, CI 1.73–1.99) and their daughters (AOR = 12.61, CI 10.86–14.64) more likely to undergo FGM. Whiles women in rural areas were less likely to undergo FGM (AOR = 0.81, CI 0.78–0.84), their daughters were more likely to undergo FGM (AOR = 1.09, CI 1.03–1.15). Married women (AOR = 1.67, CI 1.59–1.75) and their daughters (AOR = 8.24, CI 6.88–9.87) had the highest odds of undergoing ...
Despite increased access to and improvements in contraceptives, unintended pregnancy continues to be a problem globally and is associated with adverse outcomes for mothers and infants. This paper seeks to unravel the mediators of intended versus unintended pregnancies among Black women living with HIV. The paper draws on survey data from a broader multi-country mixed methods study that used a community-based participatory research approach to investigate the psychosocial experiences of Black mothers living with HIV. The study participants were Black mothers living with HIV drawn through venue-based sampling from Ottawa, Canada (n = 89), Port Harcourt, Nigeria (n = 400), and Miami, Florida, United States (n = 201). We used Hierarchical Binary Logistic Regression Modelling (HBLM) to estimate the independent associations of pregnancy intention (intended versus unintended) with blocks of predictor variables (sociodemographic, sociocultural, and psychosocial predictors) at alpha level of 0.5. Specifically, 44.2%, 67.3%, and 17.7% of the women had unintended pregnancies in Ottawa, Miami, and Port Harcourt, respectively. There were important results from the HBLM. The odds of intended relative to unintended pregnancies were (i) reduced in larger households (OR = 0.56, 95% CI = 0.36/0.87), but increased with employment (OR = 7.84, 95% CI = 1.52/40.54) and HIV knowledge (OR = 3.13, 95% CI = 1.42/6.90) in Ottawa; (ii) reduced with age (OR = 0.93, 95% CI = 0.88/0.98), but increased with marriage (OR = 2.90, 95% CI = 1.43/5.88) and social support (pregnancy (OR = 3.77, 95% CI = 1.98/7.19) in Port Harcourt; (iii) reduced with social support (OR = 0.95, 95% CI = 0.91/1.00) but increased with HIV status disclosure (OR = 1.73, 95% CI = 1.01/2.97) and the influence of specific referent (OR = 1.68, 95% CI = 1.13/2.52) in Miami-FL. The incidence of unintended pregnancy is more prevalent among Black women living with HIV in the North American cities relative to the African city. Also, unique combinations of sociodemographic, sociocultural, and psychosocial factors influence pregnancy intention in each city. This implies that policy and practices to address reproductive health needs of WLHIV must consider these contextual issues.

Au Canada, au gouvernement fédéral et dans plusieurs provinces, le principe d'offre active sert à guider la prestation des services publics en français. L'Ontario se démarque, car son approche est en partie volontaire. Il importe donc d'étudier comment les services en français sont intégrés à la gouvernance des services publics au sein de la province. Cet article puise dans les données gouvernementales existantes afin de brosser un tableau de l'offre active de services en français en santé mentale. Or, les auteurs montrent que ces données sont difficiles à obtenir et parcellaires. L'article sert à souligner des défis importants pour l'offre de services en français dans le domaine de la santé mentale en Ontario.
AbstractFemale genital mutilation (FGM) is very pervasive in Africa, with significant regional variations in the prevalence of this traditional practice. This study examined the linkages between FGM and multiple sexual partnership in Mali and Sierra Leone – two African countries with a high prevalence of FGM. Data were from the 2018 Mali and 2013 Sierra Leone Demographic and Health Surveys, and the study sample comprised 4750 women from Mali and 16,614 from Sierra Leone. Multilevel logistic regression was used for the data analysis, with reported adjusted odds ratios (aOR) and associated 95% confidence intervals. In Mali, women who had not undergone FGM were less likely to have multiple sexual partners (aOR=0.60, CI=0.38–0.96) compared with those who had undergone FGM. In Sierra Leone, women who had undergone FGM (aOR=1.15, CI=1.02–1.30) were more likely to have multiple sexual partners compared with those who had not undergone FGM. Age, level of education, wealth quintile, sex of household head, community socioeconomic status, mass media exposure, and community literacy level were found to be associated with the likelihood of multiple sexual partnership among women in Mali and Sierra Leone. Comprehensive, age-group-based risk-reduction strategies, such as abstinence education and decision-making skills (assertiveness) training, are needed to reduce girls' and young women's engagement in multiple sexual partnerships. Policy interventions, such as anti-FGM legislation and initiatives like the 'Schooling for the Female Child' initiative aimed at reducing social inequality among girls and women, might help decrease FGM and the likelihood of health-compromising behaviours like multiple sexual partnership.
The African Union Bureau of Heads of State and Government endorsed the COVID-19 Vaccine Development and Access Strategy to vaccinate at least 60% of each country's population with a safe and efficacious vaccine by 2022, to achieve the population-level immunity needed to bring the pandemic under control. Using publicly available, country-level population estimates and COVID-19 vaccination data, we provide unique insights into the uptake trends of COVID-19 vaccinations in the 15 countries that comprise the Economic Community of West Africa States (ECOWAS). Based on the vaccination rates in the ECOWAS region after three months of commencing COVID-19 vaccinations, we provide a projection of the trajectory and speed of vaccination needed to achieve a COVID-19 vaccination coverage rate of at least 60% of the total ECOWAS population. After three months of the deployment of COVID-19 vaccines across the ECOWAS countries, only 0.27% of the region's total population had been fully vaccinated. If ECOWAS countries follow this trajectory, the sub-region will have less than 1.6% of the total population fully vaccinated after 18 months of vaccine deployment. Our projection shows that to achieve a COVID-19 vaccination coverage of at least 60% of the total population in the ECOWAS sub-region after 9, 12 and 18 months of vaccine deployment; the speed of vaccination must be increased to 10, 7 and 4 times the current trajectory, respectively. West African governments must deploy contextually relevant and culturally acceptable strategies for COVID-19 vaccine procurements, distributions and implementations in order to achieve reasonable coverage and save lives, sooner rather than later.
