"If there is no water, we cannot feed our children": The far-reaching consequences of water insecurity on infant feeding practices and infant health across 16 low- and middle-income countries.

OBJECTIVES: Infant feeding plays a critical role in child health and development. Few studies to date have examined the link between household water insecurity and infant feeding, and none in a cross-cultural context. Therefore, we examined the perceived impact of household water insecurity in four domains: breastfeeding, non-breastmilk feeding, caregiver capabilities, and infant health. Our research was conducted as part of the Household Water Insecurity Experiences (HWISE) study. METHODS: We interviewed respondents from 19 sites in 16 low- and middle-income countries (N = 3303) about the link between water insecurity and infant feeding. We then thematically analyzed their open-ended textual responses. In each of the four domains (breastfeeding, non-breastmilk feeding, caregiver capabilities, infant health), we inductively identified cross-cultural metathemes. We analyzed the distribution of themes across sites quantitatively and qualitatively. RESULTS: Water was perceived to directly affect breastfeeding and non-breastmilk feeding via numerous pathways, including timing and frequency of feeding, unclean foods, and reduced dietary diversity. Water was perceived to indirectly affect infant feeding through caregiver capabilities by increasing time demands, exacerbating disease, undernutrition, and mortality, and requiring greater efficacy of caregivers. Respondents made connections between water challenges and infant health, for example, increased risk of infectious diseases, undernutrition, and mortality. CONCLUSIONS: These findings suggest that water presents many, and sometimes unexpected, challenges to infant feeding. By systematically investigating biocultural pathways by which water impacts infant and young child feeding, it will be possible to understand if, and how, water security can be leveraged to improve child nutrition and health.

U.S. Breastfeeding Outcomes at the Intersection: Differences in Duration Among Racial and Ethnic Groups With Varying Educational Attainment in a Nationally Representative Sample.

BACKGROUND: As breastfeeding rates in the United States increase, barriers persist for Black, Latine, and low-socioeconomic status household dyads when compared to White and high-socioeconomic status household dyads. Previous breastfeeding disparities research has almost exclusively considered the influence of race, ethnicity, and socioeconomic status separately, although these attributes are not randomly distributed across the population. RESEARCH AIM: To identify breastfeeding duration patterns by race/ethnicity and educational attainment in a nationally representative U.S. National Immunization Survey sample. METHOD: We conducted a cross-sectional, secondary analysis of the U.S. Centers for Disease Control and Prevention's 2020 National Immunization Survey-Child public-use data. To examine breastfeeding and exclusive breastfeeding durations at the intersection of race/ethnicity and educational attainment, we created a 12-item, cross-classified variable using three educational attainment groups and four race/ethnicity groups. We used linear regressions to test these associations. RESULTS: In all, 83% of the sample breastfed. Mean durations of breastfeeding were 7.5 (SE = 1.95) months and exclusive breastfeeding duration was 4.9 (SE = 0.87) months. In adjusted models, multi-race/other high-educational attainment participants had the longest breastfeeding duration by almost 3 weeks (ß: 19.53, 95% CI [5.27, 33.79]), and Black low-educational attainment participants exclusively breastfed for 1 month less than White high-educational attainment participants (ß:-30.23, 95% CI [-40.87, -19.58]). CONCLUSIONS: Examining race/ethnicity and educational attainment together provides an intersectional understanding of breastfeeding outcomes and can inform targeted, culturally appropriate interventions.

Perinatal depressive symptoms and breastfeeding behaviors: A systematic literature review and biosocial research agenda.

BACKGROUND: Breastfeeding is recommended to improve maternal and infant health globally. Depression has been posited to negatively impact breastfeeding, although potential causal and bidirectional pathways between these two phenomena have not been sufficiently characterized. We therefore conducted a systematic review to critically evaluate available evidence on the relationship between perinatal depressive symptoms and breastfeeding behaviors; to identify knowledge gaps and propose a biosocial research agenda to advance our understanding of this topic. METHODS: A systematic search strategy was applied across seven databases. Data were extracted and aggregated using the matrix method to provide a narrative synthesis of findings. RESULTS: Thirty-eight studies from 20 countries spanning 1988 through 2018 fit the inclusion criteria. In general, methods across studies were heterogeneous. Fourteen different tools were used to measure perinatal depressive symptoms. Nearly half the studies did not provide breastfeeding definitions. No studies from low-income countries met inclusion criteria. More than half (63%) of studies demonstrated a negative association between depressive symptoms across the perinatal period and less exclusive breastfeeding and/or shorter breastfeeding durations. LIMITATIONS: Heterogeneity in study design, definitions, assessment tools, and measurement time points limited the comparability of study findings. Causality cannot be assessed. CONCLUSIONS: Available evidence suggests perinatal depressive symptoms negatively associated with breastfeeding exclusivity and duration, which can lead to suboptimal infant nutrition and detrimental impacts on maternal mental and physical health. To better understand this relationship, we propose including consistent operationalization and assessment of depression and breastfeeding globally and concurrent repeated measures of key biological and social factors.
