The burden of suboptimal breastfeeding in Mexico: Maternal health outcomes and costs

Associations Between Breastfeeding, Maternal Emotional Availability, and Infant-Mother Attachment: The Role of Coparenting

BACKGROUND

Breastfeeding is a parenting practice that combines close intimate contact with the opportunity to be sensitive and responsive to the infant, and may have direct and indirect relations with infant attachment. However, researchers have produced inconsistent findings, suggesting there may be other mechanisms involved. Coparenting may play a significant role, as it has been consistently associated with mother-infant relationships.

RESEARCH AIMS

The aims of this study were to examine: (1) whether breastfeeding would be directly associated with infant-mother attachment; (2) whether this association was also indirect, through mothers' quality of caregiving; and (3) whether partners' coparenting support moderates breastfeeding's indirect association with attachment.

METHODS

This was a prospective, longitudinal study that drew data from a larger NIH-funded study on sleep and family relationships (R01HD052809). Mothers reported on their feeding practices and coparenting relationships. Independent observations were used to assess mothers' emotional availability toward infants. A separate team of observers assessed infant-mother attachment.

RESULTS

Exclusive breastfeeding during the first 6 months, and longer duration of any breastfeeding across the 1st year, were directly associated with more secure infant-mother attachment. These associations were also indirect, through maternal emotional availability. Coparenting was a significant moderator, such that the influence of longer breastfeeding duration on improved emotional availability, and, in turn, on more secure attachment, was significant only for mothers who perceived coparenting quality to be low.

CONCLUSION

Findings highlighted the importance of breastfeeding on both the quality of mothering and infant attachment, but also emphasized that coparenting support may be particularly important for mothers who are unable to breastfeed.

Breastfeeding is associated with the intelligence of school-age children in Mexico

Breastfeeding has been consistently associated with higher intelligence since childhood. However, this relation could be confounded due to maternal selection bias. We estimated the association between predominant breastfeeding and intelligence in school-age children considering potential selection bias and we simulated the intelligence gap reduction between low versus higher socioeconomic status children by increasing breastfeeding. We analysed predominant breastfeeding practices (breastmilk and water-based liquids) of children 0-3 years included in the Mexican Family Life Survey (MxFLS-1). Intelligence was estimated as the z-score of the abbreviated Raven score, measured at 6-12 years in the MxFLS-2 or MxFLS-3. We predicted breastfeeding duration among children with censored data with a Poisson model. We used the Heckman selection model to assess the association between breastfeeding and intelligence, correcting for selection bias and stratified by socioeconomic status. Results show after controlling for selection bias, a 1-month increase in predominant breastfeeding duration was associated with a 0.02 SD increase in the Raven z-score (p < 0.05). The children who were predominantly breastfed for 4-6 months versus <1 month had 0.16 SD higher Raven z-score (p < 0.05). No associations were found using multiple linear regression models. Among low socioeconomic status children, increasing predominantly breastfeeding duration to 6 months would increase their mean Raven z-score from -0.14 to -0.07 SD and reduce by 12.5% the intelligence gap with high socioeconomic status children. In conclusion, predominant breastfeeding duration was significantly associated with childhood intelligence after controlling for maternal selection bias. Increased breastfeeding duration may reduce poverty-driven intelligence inequities.

Sociodemographic and Personal Predictors of Exclusive Breastfeeding in Pregnant Mexican Women Using Public Health Services

Exclusive breastfeeding (EBF) is a cost-effective healthy behavior for the mother–child dyad. Globally, rates of EBF are low. Little research has been conducted on the joint role of modifiable and nonmodifiable variables in pregnant women’s decision-making. The aim was to develop and test a model that used personal and sociodemographic factors to predict whether pregnant women who use public healthcare services plan to breastfeed. In a nonprobabilistic sample of 728 pregnant Mexican women, self-efficacy, the planned behavior theory constructs, and the intention to breastfeed (BFI) were measured. A total 60% of the sample was randomly chosen to develop a predictive multivariate logistic regression model. The model was validated in the remaining 40%. Women in the highest tertiles of attitudes and self-efficacy had fourfold increased chances of having a high BFI (OR 4.2, 95% CI [2.4, 7.4]). Working was associated with a decreased intention to exclusively breastfeed (OR 0.61, 95% CI [0.37, 0.98]). The model predicted BFI with a sensitivity of 38.3% and specificity of 82.2%. While personal variables predict the BFI, working decreases women’s chances of breastfeeding. The results can be utilized to develop primary prevention strategies to help mothers who use public health services to breastfeed.

¿Consejería para la madre lactante o para la técnica de lactancia materna?

Introducción. En Colombia, pese a la implementación de iniciativas como la consejería en lactancia materna (CLM), las tasas de lactancia materna exclusiva (LME) son bajas. Objetivo. Comprender la experiencia de un grupo de madres lactantes respecto a la consejería en lactancia materna exclusiva (CLME) recibida en Instituciones Amigas de la Mujer y la Infancia (IAMI) en Bogotá D.C., Colombia. Materiales y métodos. Investigación cualitativa con enfoque fenomenológico. Se aplicaron entrevistas a profundidad a 19 madres lactantes que recibieron CLME en 3 IAMI entre agosto de 2016 y enero de 2017. Las unidades de significado (US) se identificaron mediante un análisis comprensivo realizado en el programa N-Vivo versión 10 y basado en la lectura de las transcripciones textuales de las entrevistas y la identificación de estructuras esenciales en los relatos relacionadas con la experiencia que tuvieron durante la CLME en tres momentos (gestación, parto/posparto inmediato y puerperio). Resultados. La edad promedio fue de 23 años. Solo el 37% lactó exclusivamente hasta los 4 meses. Se identificaron 9 US. Durante la gestación y el posparto inmediato las madres recibieron indicaciones sobre como lactar, pero no recibieron CLME por parte del personal de salud. En el puerperio, la familia y la red de apoyo de las madres les brindaron ayuda y acompañamiento respecto a la lactancia materna. Conclusión. Es posible que en el país no se estén cumpliendo las disposiciones legales sobre la CLM e iniciativas como las IAMI, ya que se evidencian dificultades para su correcta realización, por lo que es necesario plantear y desarrollar estrategias efectivas para la formación de consejeros en lactancia materna entre el personal de salud.

Perceived insufficient milk among primiparous, fully breastfeeding women: Is infant crying important?

Breastfeeding mothers often report perceived insufficient milk (PIM) believing their infant is crying too much, which leads to introducing formula and the early abandonment of breastfeeding. We sought to determine if infant crying was associated with reported PIM (yes/no) and number of problems associated with lactation (lactation problem score [LPS] 6-point Likert scale) before formula introduction. Primiparous breastfeeding mothers were recruited at birth and visited at 1, 2 and 4 weeks. Among those fully breastfeeding at 1 week (N = 230), infant crying variables based on maternal reports were not associated with PIM at 1 week, but LPS was. However, a mother's expectation that her infant would cry more than other infants was associated with increased odds of reporting PIM at 2 and 4 weeks, as were delayed onset of lactation and previous LPS. At 1 week, crying variables (frequency, difficulty in soothing) were associated with LPS along with percent weight change. Delayed onset of lactation, infant care style, number of breastfeeds and previous LPS were longitudinally associated with change in LPS from 1 to 2 weeks and 2 to 4 weeks. Our data suggest that reported infant crying is associated with PIM and LPS in the first 4 weeks of life. Guidance on what to expect in crying behaviour and the impact of infant care style may be beneficial in reducing PIM and LPS in the first month.

Breastfeeding practices in Mexico: Results from the National Demographic Dynamic Survey 2006-2018

Although actions have been taken to improve breastfeeding in Mexico, trends over the last decade and their associated factors have not been analysed. We estimated trends in breastfeeding practices at the national, rural/urban, and regional level indigenous ethnicity and socio-economic level, and their associated factors using the National Demographic Dynamics Survey (2006, 2009, 2014 and 2018). We assessed breastfeeding indicators of women with children <24 months according to The World Health Organization recommendations. Logistic regressions models of pooled data were used to estimate trends and associations with biological and sociodemographic characteristics. Between 2006 and 2018, the prevalence of ever breastfed increased from 91.8% to 94.2% (p < 0.001), whereas early initiation of breastfeeding increased from 40.8% to 59.7% (p < 0.001), with similar increments by urban/rural level. Between 2009 and 2018, the prevalence of exclusive breastfeeding in children <6 months increased from 13.0% to 20.7% (p < 0.001). The largest increase was seen in Mexico City, in nonindigenous women and those with a high socio-economic status, whereas indigenous women and those from the South had the lowest or no improvements. Breastfeeding education during pregnancy [odds ratio (OR) 1.3; 95% confidence interval (CI) 1.1-1.5] was positively associated with exclusive breastfeeding, whereas being employed (OR 0.8; 95% CI 0.6-0.9) was negatively associated. Breastfeeding practices improved but are still far from recommendations. Implementing strategies like breastfeeding counselling and programmes and policies that promote and support breastfeeding for poor, indigenous, single and working mothers should be a priority for the government to ensure that all children have the best start in life.

Persistent Malnutrition and Associated Factors among Children under Five Years Attending Primary Health Care Facilities in Limpopo Province, South Africa

Despite years of interventions intended to reduce child malnutrition in South Africa, its negative effects, stunting in particular, persist mainly among children under five years old living in under-resourced regions. A cross-sectional study was conducted to determine the prevalence of malnutrition and associated factors among 404 children under age five attending childcare services with their mothers in selected healthcare facilities of Limpopo Province, South Africa. Anthropometry, socio-demographics and obstetric history were collected. Height-for-age, weight-for-age and body mass index-for-age Z-scores were used to determine stunting, underweight and thinness among children, respectively. Logistic regression analyses were performed to generate the factors associated with malnutrition. Stunting (45.3%) was the prevalent form of malnutrition among children under age five, affecting boys (51.7%) more than girls (38.8%) and children aged 12–23 months (62.4%) more than those <11 months old (40.1%), in addition to the overall prevalence of underweight (29.0%) and thinness (12.6%). Boys had increased odds of stunting (adjusted odds ratio, AOR = 2.07, 95% CI: 1.26–3.41, p = 0.004) and underweight (AOR = 2.17, 95% CI: 1.32–3.57, p = 0.002) than girls. Children aged 12–23 months were more likely to be stunted (AOR = 4.79, 95% CI: 2.36–9.75, p ≤ 0.0001) than children aged ≤11 months. Delayed introduction of solid foods increased the odds of stunting (AOR = 5.77, 95% CI: 2.63–12.64, p ≤ 0.0001) and underweight (AOR = 2.05, 95% CI: 1.08–3.89, p = 0.028). Children with normal birth weight were less likely to be thin (AOR = 0.42, 95% CI: 0.19–0.92, p = 0.029) and underweight (AOR = 0.34, 95% CI: 0.17–0.68, p = 0.003) than children who had low birth weight. Children whose mothers had obtained secondary school education (AOR = 0.39, 95% CI: 0.16–0.97, p = 0.044), and Grade 12 or post-Grade 12 education (AOR = 0.32, 95% CI: 0.12–0.83, p = 0.020) were less likely to be stunted than were children of mothers who had only primary school education. Suboptimal complementary feeding predisposed children to stunting and underweight. National nutrition programs should be context-specific to improve the introduction of complementary foods among children, especially in the remote and poor areas.

Improving Breastfeeding by Empowering Mothers in Vietnam: A Randomised Controlled Trial of a Mobile App

Breastfeeding provides benefits to the infant and mother; however, the rates of breastfeeding, particularly exclusive breastfeeding, remain below optimal levels in many Asian countries. The aim of this study is to review the benefits of breastfeeding to mothers and infants and current rates of breastfeeding in Vietnam, and to evaluate the effectiveness of a mobile application on exclusive breastfeeding among mothers in Vietnam. A two-arm, parallel triple-blinded randomised controlled trial will be conducted among 1000 mothers in Hanoi City, Vietnam, during 2020-2021. Eligible participants are pregnant women who will seek antenatal care from health facilities at 24-36 weeks of gestation and plan to deliver at two participating hospitals, own a smartphone, and carry a singleton foetus. Permuted-block randomisation method stratified by maternal age, education and parity will be used to ensure an equal number of participants in each group. A smartphone app will be developed to deliver breastfeeding and non-breastfeeding information to the intervention and control group, respectively. Data will be collected at baseline, before hospital discharge, and at 1, 4, and 6 months postpartum. This study envisages demonstrating whether a smartphone-based intervention can be effective at improving breastfeeding in Vietnam. Trials registration: ACTRN12619000531112.

Social circumstances and cultural beliefs influence maternal nutrition, breastfeeding and child feeding practices in South Africa

BACKGROUND

Maternal and child undernutrition remain prevalent in developing countries with 45 and 11% of child deaths linked to poor nutrition and suboptimal breastfeeding, respectively. This also has adverse effects on child growth and development. The study determined maternal dietary diversity, breastfeeding and, infant and young child feeding (IYCF) practices and identified reasons for such behavior in five rural communities in South Africa, in the context of cultural beliefs and social aspects.

METHODS

The study used mixed methodology technique. Questionnaires were administered to 84 households, pairing mother/caregiver and a child (0-24 months old) to obtain information on maternal dietary diversity, IYCF and breastfeeding practices. Qualitative data on breastfeeding perceptions, IYCF practices, perceived eating habits for lactating mothers and cultural beliefs related to mothers' decision on IYCF and breastfeeding practices were obtained through focus group discussions.

RESULTS

Maternal dietary diversity was very low and exclusive breastfeeding for the first 6 months of life was rarely practiced, with young children exposed to poor-quality diets lacking essential nutrients for child growth and development. Social circumstances including lack of income, dependence on food purchasing, young mothers' feelings regarding breastfeeding and cultural beliefs were the major drivers of mothers' eating habits, breastfeeding behaviour and IYCF practices. Fathers were left out in breastfeeding and IYCF decision making and young mothers were unwilling to employ indigenous knowledge when preparing food (especially traditional foods) and feeding their children.

CONCLUSION

The study provides comprehensive information for South African context that can be used as an intervention measure to fight against malnutrition in young children. Finding a balance between mothers' income, dietary diversity, cultural beliefs, breastfeeding and considering life of lactating mothers so that they won't feel burdened and isolated when breastfeeding and taking care of their children is crucial. Paternal inclusion in breastfeeding decisions and safeguarding indigenous knowledge on IYCF practices is recommended.

The burden of suboptimal breastfeeding in Mexico: Maternal health outcomes and costs

Longer duration of breastfeeding is associated with a lower risk of type 2 diabetes, breast and ovarian cancer, myocardial infarction, and hypertension diseases in women. Mexico has one of the lowest breastfeeding rates worldwide; therefore, estimating the disease and economic burden of such rates is needed to influence public policy. We considered suboptimal breastfeeding when fewer than 95% of parous women breastfeed for less than 24 months per child, according to the World Health Organization recommendations. We quantified the lifetime excess cases of maternal health outcomes, premature death, disability-adjusted life years, direct costs, and indirect costs attributable to suboptimal breastfeeding practices from Mexico in 2012. We used a static microsimulation model for a hypothetical cohort of 100,000 Mexican women to estimate the lifetime economic cost and disease burden of type 2 diabetes, breast and ovarian cancer, myocardial infarction, and hypertension in mothers, due to suboptimal breastfeeding, compared with an optimal scenario of 95% of parous women breastfeeding for 24 months. We expressed cost in 2016 USD. We used a 3% discount rate and tested in sensitivity analysis 0% and 5% discount rates. We found that the 2012 suboptimal scenario was associated with 5,344 more cases of all analysed diseases, 1,681 additional premature deaths, 66,873 disability-adjusted life years, and 561.94 million USD for direct and indirect costs over the lifetime of a cohort of 1,116 million Mexican women. Findings suggest that investments in strategies to enable more women to optimally breastfeed could result in important health and cost savings.
