Abstract
IntroductionDespite the health benefits of breastfeeding for both the mother and the child, early cessation of breastfeeding remains a public health problem in South Africa, attributed to contextual barriers and facilitators. Within the context of Mpumalanga province, which is characterized by low breastfeeding rates and high infant mortality rates in children under 5 years, we explored the facilitators and barriers to breastfeeding among mothers attending the three primary health facilities in Ermelo.MethodsUsing a semi-structured interview guide suggested by the socio-ecological model, three focus group discussions and 12 in-depth interviews were conducted among mothers selected using a purposive sampling. Transcripts from audiotaped and transcribed verbatim interviews were assessed through thematic analysis using NVivo version 10.ResultsMothers were aged between 18 and 42 years and from poor sociodemographic backgrounds. At the individual level, mothers valued breastfeeding facilitated by their commitment, maintaining it, eating healthy foods, and having sufficient breast milk. However, returning to work, insufficient breast milk, misconceptions about breastfeeding, and interference with social life were the barriers for mothers to breastfeed continuously. At the interpersonal level, the family was identified as the main form of support to breastfeeding mothers; however, family interference was also identified as a barrier. At the community level, mothers shared some family beliefs and practices but were still split between societal and cultural norms and traditional beliefs as facilitators or barriers to breastfeeding. At the organizational level, most mothers valued the support provided by healthcare workers on childcare and techniques for breastfeeding at the health facilities. They did however articulate concerns on the miscommunication some healthcare workers offered regarding breastfeeding, which negatively influenced their infant feeding practices.DiscussionIntervention efforts should focus on behaviour change to educate and equip mothers to overcome the barriers that are within their control. Such interventions should further focus on family-centered education and strengthening the proficiency of healthcare workers on advising breastfeeding mothers.

Abstract
OBJECTIVE In many countries, the provision of water in the early months of a baby's life jeopardises exclusive breast-feeding (EBF). Using a behavioural theory, this study assessed the impact of a behaviour change intervention on mothers' intention to act and, in turn, on the water provision in addition to breast milk to their infants under 6 months of age (IU6M) in two regions of Guinea. DESIGN A quasi-experimental design. Data on individual and environmental factors of the theoretical framework, sociodemographic and outcomes were collected using validated questionnaires before and after the intervention. The outcomes examined were the intention to provide water to IU6M, the provision of water and EBF. Path analyses were performed to investigate pathways by which psychosocial and environmental factors influenced the water provision in addition to breast milk. SETTING Four health centres were assigned randomly to each study's arm (one control/CG and one intervention group/IG per region). PARTICIPANTS The sample included 300 mothers of IU6M: 150 per group. RESULTS In IG, the proportion of mothers providing water decreased from 61 % to 29 % before and after the intervention (P < 0·001), while no difference was observed in CG (P = 0·097). The EBF rate increased in IG (from 24·0 % to 53·8 %, P < 0·001) as opposed to CG (36·7 % to 45·9 %, P = 0·107). An association (P < 0·001) between the intention and the behaviour was observed in both groups. CONCLUSIONS An intervention developed using a sound framework reduces the provision of water among IU6M and improves EBF.

Abstract
BACKGROUND Children need good nutrition to develop proper immune mechanisms and psychosocial maturity, but malnutrition can affect their ability to realize this. Apart from the national demographic and health survey, which is carried out every 5 years, there have not been enough documented studies on child breastfeeding and weaning practices of caregivers in the Volta Region. We, therefore, examined child breastfeeding and weaning practices of mothers in the Volta Region of Ghana. METHODS A sub-national survey method was adopted and a semi-structured questionnaire was used to collect data from 396 mothers and their children. Descriptive and inferential statistics comprising frequency, percentage, chi-square, and logistic regression were employed in analysing the data. We defined exclusive breastfeeding as given only breast milk to an infant from a mother or a wet nurse for six months of life except drops or syrups consisting of vitamins, minerals, supplements, or medicines on medical advice, and prolonged breastfeeding as breastfeeding up to 24 months of age. RESULTS The prevalence of exclusive breastfeeding (EBF) was 43.7%. Mothers constituting 61.1% started breastfeeding within an hour of giving birth. In addition to breast milk, 5.1% gave fluids to their children on the first day of birth. About 66.4% started complementary feeding at 6 months, 22.0% breastfed for 24 months or beyond, while 40.4% fed their children on-demand. Child's age (AOR: 0.23, 95% CI:0.12-0.43, p<0.0001), prolonged breastfeeding (AOR: 0.41, 95%CI: 0.12-0.87, p = 0.001), mother's religion (AOR: 3.92, 95%CI: 1.23-12.61, p = 0.021), feeding practices counselled on (AOR: 1.72, 95%CI: 1.96-3.09, p = 0.023), mother ever heard about EBF (AOR: 0.43, 95%CI: 1.45-2.41, p = 0.039), child being fed from the bottle with a nipple (AOR: 1.53, 95%CI: 1.94-2.48, p = 0.003), and age at which complementary feeding was started (AOR: 17.43, 95%CI: 3.47-87.55, p = 0.008) were statistically associated with EBF. CONCLUSION Breastfeeding education has been ongoing for decades, yet there are still gaps in the breastfeeding practices of mothers. To accelerate progress towards attainment of the sustainable development goal 3 of ensuring healthy lives and promoting well-being for all at all ages by the year 2030, we recommend innovative policies that include extensive public education to improve upon the breastfeeding and weaning practices of mothers.

A systematic review of qualitative research on barriers and facilitators to exclusive breastfeeding practice in sub-Saharan African countries. Int Breastfeed J 2021; 16:44. [PMID: 34090461 PMCID: PMC8178897 DOI: 10.1186/s13006-021-00380-6] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/17/2020] [Accepted: 04/04/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Studies reporting factors associated with exclusive breastfeeding are mostly quantitative. No study has performed a systematic qualitative summary to document the recurring constraints and facilitators to exclusive breastfeeding in sub-Saharan African countries from breastfeeding mothers' perspective. This study systematically reviews the literature reporting barriers and facilitators to exclusive breastfeeding from the breastfeeding mothers' perspective in sub-Saharan Africa to develop an educational intervention to optimize exclusive breastfeeding. METHODS A systematic literature review of qualitative studies such as phenomenological studies, followed by a risk of bias and methodological assessment of the included studies' quality using the Critical Appraisal Skills Programme (CASP) tool was conducted. MEDLINE and Google Scholar were searched from January 1990 to October 2019 to retrieve studies of breastfeeding mothers who had infants aged between 0 and 12 months. Two authors independently carried out the review process and resolved disagreements through consensus. We analyzed the data thematically. RESULTS After reviewing 92 studies, 20 studies involving 836 participants from 11 countries were eligible. Of the 72 studies excluded, 39 were not conducted in sub-Saharan Africa, and 33 included other participants such as fathers. Three themes emerged as barriers to exclusive breastfeeding (EBF) and five additional themes were identified with facilitators of maternal-infant factors being the most significant in both cases. Maternal employment and knowledge of the benefits of EBF were the most common maternal-infant factors that served as a barrier and a facilitator, respectively. The study's limitations were that the review involved only primary research among breastfeeding mothers living in sub-Saharan Africa and excluded studies not available in the English language. The information synthesized from this review could be used to develop communication strategies employed during individual and group patient education in the hospitals to improve breastfeeding mothers' understanding, acceptance, and practice of exclusive breastfeeding. This review was prospectively registered with the International Prospective Register of Systematic Reviews (PROSPERO), registration number CRD42020133761. CONCLUSIONS This review found that maternal-infant factors have the most significant influence over the practice of exclusive breastfeeding. Therefore, interventions targeted towards maternal-infant factors will improve and optimize exclusive breastfeeding significantly and, ultimately, improve maternal-child health outcomes.

Abstract
Developing countries grapple with poor maternal health outcomes, and the Niger Delta is no exception. Discourses in the Niger Delta have been dominated by oil resource, with suboptimal attention paid to health outcomes in the region. This study investigated barriers to utilization of maternal health care services in the Okrika local government area of Rivers State, Nigeria. Data were sourced through focus group discussions organized for 21 health care professionals and 24 mothers residing in the area. Analysis was done thematically, relying on relevant qualitative analytical tools. Poor income, ignorance, absence of social support, religion and culture, and health care system inefficiencies were the barriers associated with utilization of maternal health care services. It was clear that maternal health outcomes and the state of health care generally in the Niger Delta do not reflect the enormous resources generated from oil that is plentiful in the region. Results point to an evident need for social work expertise to mitigate these barriers in view of improving health outcomes in the region.

Abstract
Background Nigeria is one of the ten countries globally that account for 62% of under- and unvaccinated children worldwide. Despite several governmental and non-governmental agencies’ interventions, Nigeria has yet to achieve significant gains in childhood immunization coverage. This study identifies intrapersonal, interpersonal, organizational, community, and policy-level factors that influence childhood immunization uptake from various stakeholders’ perspectives using the Socioecological Model (SEM). Methods Using the Socioecological Model as a guiding framework, we conducted ten focus group sessions with mothers/caregivers and community leaders residing in Lagos state and nine semi-structured interviews with healthcare workers who provide routine immunization services in Lagos state primary healthcare facilities. We performed a qualitative analysis of focus groups and semi-structured interviews using deductive coding methods. Results The study sample included 44 mothers/caregivers and 24 community leaders residing in Lagos State, Nigeria, and 19 healthcare workers (routine immunization focal persons) working in the primary healthcare setting in Lagos state. Study participants discussed factors at each level of the SEM that influence childhood immunization uptake, including intrapersonal (caregivers’ immunization knowledge, caregivers’ welfare and love of child/ren), interpersonal (role of individual relationships and social networks), organizational (geographical and financial access to health facilities, health facilities attributes, staff coverage, and healthcare worker attributes), community (community outreaches and community resources), and policy-level (free immunization services and provision of child immunization cards). Several factors were intertwined, such as healthcare workers’ education of caregivers on immunization and caregivers’ knowledge of vaccination. Conclusions The reciprocity of the findings across the Socioecological Model levels emphasizes the importance of developing multi-pronged interventions that operate at multiple levels of the SEM. Our results can inform the design of culturally appropriate and effective interventions to address Nigeria’s suboptimal immunization coverage.

Abstract
PURPOSE Although exclusive breastfeeding (EBF) is known to have positive consequences for mothers and infants, EBF rate in Nigeria is <25%. This study investigated if social factors were stronger predictors of EBF than bio-medical factors in the metropolitan areas of Lagos and Taraba States. Social factors included mother's education, infant sex, place of birth, and nature of mother's employment, while bio-medical factors included nature of birth (whether vaginal or caesarean section), problems with breast/nipple, breast milk insufficiency, and mother's age. DESIGN AND METHODS The study adopted a cross-sectional survey design and mixed method of data collection. From the two states, 500 mothers with babies between 7 and 12 months of age completed a structured questionnaire. Twenty respondents from each state were interviewed using an in-depth interview guide. RESULTS Education (β = 1.743; p < 0.001), infant sex (β = -0.454; p < 0.05), and place of delivery (β = -1.552; p < 0.001) were significant social predictors. Breast milk insufficiency (β = -1.851; p < 0.001) and mother's age (β = 0.064; p < 0.001) were significant bio-medical predictors. When all the eight factors were considered, only two of the three social factors, namely, education and infants' sex, remained significant, while three bio-medical factors, namely, breast milk insufficiency, mother's age, and nature of delivery, were significant. CONCLUSIONS Social and bio-medical factors co-determine the practice of EBF and must not be considered dichotomous. PRACTICAL IMPLICATIONS Interventions to encourage EBF among Nigerian mothers must focus on education regarding its benefits and correction of misconceptions that breast milk alone is insufficient as an infant's diet.

Abstract
Background Chinese mothers of preterm infants often face obstacles to breastfeeding and commonly experience prolonged maternal-infant separation when their high-risk infants are hospitalized in a Neonatal Intensive Care Unit (NICU). This separation hinders mother-infant attachment and the establishment of breastfeeding. Currently, little is known about Chinese mothers’ experiences breastfeeding their preterm infants, or their support needs. The aim of this study was to develop an understanding of mothers’ experiences breastfeeding a hospitalized preterm infant and the support needed to establish a milk supply during the period separation from their infants. Methods A qualitative descriptive study was conducted in Beijing in 2017. A total of 11 Chinese mothers were individually interviewed while separated from their infants. The interviews were audio-recorded and transcribed verbatim. A thematic analysis involving a seven-step protocol identified key themes. Results Mothers of preterm infants reported physically and mentally challenging breastfeeding experiences during the period they were separated from their babies. They viewed expressing breast milk as integral to their maternal role, even though some found expressing breastmilk exhausting. With little professional support available, the mothers depended upon nonprofessionals to establish breastfeeding. Conclusions The study identified the difficulties mothers experienced establishing a milk supply while separated from their preterm infants, and the importance of access to health professional support.
