Breastfeeding in the pandemic: A qualitative analysis of breastfeeding experiences among mothers from Canada and the United Kingdom

BACKGROUND

Previous research shows that the COVID-19 pandemic resulted in both barriers and facilitators to breastfeeding. However, little research has looked specifically at first-time mothers' experiences of breastfeeding during the pandemic or compared experiences of mothers living in different countries.

AIM

This research explores mothers' breastfeeding experiences to describe how the COVID-19 pandemic has affected breastfeeding journeys in Canada and the United Kingdom.

METHODS

Ten semi-structured online interviews were undertaken with first-time mothers who breastfed their baby at least once during the COVID-19 pandemic and are living in Canada or the United Kingdom. Interview transcripts were coded inductively using thematic analysis.

FINDINGS

One overarching theme (all on mother) and four sub-themes were identified: 1) accessing and advocating for health care, 2) social support, 3) becoming a mother in isolation, and 4) breastfeeding baby. Similar themes were constructed for both countries.

DISCUSSION

Mothers reported that diminished health care and social support created challenges in their breastfeeding journey. Many mothers reported receiving virtual breastfeeding support, which was largely experienced as unhelpful. Some mothers reported fewer distractions from visitors and more one-on-one time with their infant, which helped them to establish breastfeeding and a strong mother-infant bond.

CONCLUSION

In both Canada and the United Kingdom, new mothers need consistent, reliable health care and social support when breastfeeding. This study supports the need to protect breastfeeding support in the midst of a global emergency and beyond to ensure positive breastfeeding experiences for both mother and baby.

Breastfeeding self-efficacy predicts breastmilk feeding in preterm infants at discharge from the neonatal intensive care unit

AIM

To examine the association between breastfeeding self-efficacy (BSE) and breastmilk feeding at discharge from the neonatal intensive care unit among mothers of preterm infants.

DESIGN

Secondary analysis of the Family Integrated Care (FICare) cluster randomized controlled trial.

METHODS

Data from 221 mothers of preterm infants who participated in the standard care group of the trial were analysed. BSE at admission was assessed using the modified Breastfeeding Self-Efficacy Scale-Short Form (BSES-SF). Breastmilk feeding was assessed using 24 hr maternal recall at discharge.

RESULTS

Mothers who were exclusively breastmilk feeing their infants at discharge had statistically significantly higher mean BSES-SF scores at admission (68.4, SD = 13.7) than those providing a combination of breastmilk and formula or only formula (59.6, SD = 14.7; p < .001). Multivariable logistic regression showed that higher BSE at admission, maternal birth in Canada, and absence of diabetes were statistically significant predictors of exclusive breastmilk feeding at discharge.

The international Perinatal Outcomes in the Pandemic (iPOP) study: protocol

Preterm birth is the leading cause of infant death worldwide, but the causes of preterm birth are largely unknown. During the early COVID-19 lockdowns, dramatic reductions in preterm birth were reported; however, these trends may be offset by increases in stillbirth rates. It is important to study these trends globally as the pandemic continues, and to understand the underlying cause(s). Lockdowns have dramatically impacted maternal workload, access to healthcare, hygiene practices, and air pollution - all of which could impact perinatal outcomes and might affect pregnant women differently in different regions of the world.

In the international Perinatal Outcomes in the Pandemic (iPOP) Study, we will seize the unique opportunity offered by the COVID-19 pandemic to answer urgent questions about perinatal health. In the first two study phases, we will use population-based aggregate data and standardized outcome definitions to: 1) Determine rates of preterm birth, low birth weight, and stillbirth and describe changes during lockdowns; and assess if these changes are consistent globally, or differ by region and income setting, 2) Determine if the magnitude of changes in adverse perinatal outcomes during lockdown are modified by regional differences in COVID-19 infection rates, lockdown stringency, adherence to lockdown measures, air quality, or other social and economic markers, obtained from publicly available datasets. We will undertake an interrupted time series analysis covering births from January 2015 through July 2020.

The iPOP Study will involve at least 121 researchers in 37 countries, including obstetricians, neonatologists, epidemiologists, public health researchers, environmental scientists, and policymakers. We will leverage the most disruptive and widespread “natural experiment” of our lifetime to make rapid discoveries about preterm birth. Whether the COVID-19 pandemic is worsening or unexpectedly improving perinatal outcomes, our research will provide critical new information to shape prenatal care strategies throughout (and well beyond) the pandemic.

Breastfeeding and the origins of health: Interdisciplinary perspectives and priorities

Breastfeeding and human milk (HM) are critically important to maternal, infant and population health. This paper summarizes the proceedings of a workshop that convened a multidisciplinary panel of researchers to identify key priorities and anticipated breakthroughs in breastfeeding and HM research, discuss perceived barriers and challenges to achieving these breakthroughs and propose a constructive action plan to maximize the impact of future research in this field. Priority research areas identified were as follows: (1) addressing low breastfeeding rates and inequities using mixed methods, community partnerships and implementation science approaches; (2) improving awareness of evidence-based benefits, challenges and complexities of breastfeeding and HM among health practitioners and the public; (3) identifying differential impacts of alternative modes of HM feeding including expressed/pumped milk, donor milk and shared milk; and (4) developing a mechanistic understanding of the health effects of breastfeeding and the contributors to HM composition and variability. Key barriers and challenges included (1) overcoming methodological limitations of epidemiological breastfeeding research and mechanistic HM research; (2) counteracting 'breastfeeding denialism' arising from negative personal breastfeeding experiences; (3) distinguishing and aligning research and advocacy efforts; and (4) managing real and perceived conflicts of interest. To advance research on breastfeeding and HM and maximize the reach and impact of this research, larger investments are needed, interdisciplinary collaboration is essential, and the scientific community must engage families and other stakeholders in research planning and knowledge translation.

Does breastfeeding self-efficacy theory apply to mothers of moderate and late preterm infants? A qualitative exploration

BACKGROUND

Breastmilk feeding reduces morbidities and improves outcomes related to prematurity. However, breastmilk feeding rates in preterm infants are substantially lower than those in term infants. Breastfeeding self-efficacy theory is a social change theory, which is predictive of exclusive breastmilk feeding at 2 months postpartum in mothers of full-term infants. However, this theory has not been well explored in mothers of moderate and late preterm infants.

AIMS AND OBJECTIVES

To explore maternal experiences with feeding moderate (32^0/7 - 33^6/7  weeks' gestational age) and late preterm infants (34^0/7 - 36^6/7  weeks' GA) in neonatal intensive care units and assess applicability of breastfeeding self-efficacy theory.

METHODS

We conducted a qualitative descriptive exploration of maternal experiences with infant feeding in neonatal intensive care units. Using purposive, maximum variation sampling, we selected mothers of preterm infants born at 32^0/7 - 34^6/7  weeks, who experienced high mean differences in their BSE scores between admission and discharge. Fourteen mothers participated in semi-structured telephone interviews. Data were examined using thematic analysis. To explore and describe breastfeeding self-efficacy within the context of neonatal intensive care units, we super-imposed the four sources of information from breastfeeding self-efficacy theory onto the defined themes.

RESULTS

Three main themes emerged: (a) institutional influences, (b) relationship with the pump and (c) establishing breastfeeding, with an emphasis on the importance of direct breastfeeding at discharge. Overlaying the four sources of information from breastfeeding self-efficacy highlighted the presence of three sources of information: verbal persuasion, performance accomplishment and physiologic/affective responses. Vicarious experience was not identified in maternal experiences with infant feeding.

CONCLUSION

Our findings indicate that breastfeeding self-efficacy is an applicable theory for mothers of preterm infants.

RELEVANCE TO CLINICAL PRACTICE

Healthcare providers need to be aware of the influence that institutional culture and policies may have on maternal breastfeeding self-efficacy and breastfeeding outcomes.

Breastfeeding self-efficacy and breastmilk feeding for moderate and late preterm infants in the Family Integrated Care trial: a mixed methods protocol

BACKGROUND

Breastmilk is the ideal nutrition for preterm infants. Yet, breastmilk feeding rates among preterm infants are substantially lower than those of full-term infants. Barriers incurred through hospital care practices as well as the physical environment of the neonatal intensive care unit (NICU) can result in physical and emotional separation of infants from their parents, posing a substantial risk to establishing and maintaining breastfeeding. Additionally, current practitioner-focused care provision in the NICU can result in decreased breastfeeding self-efficacy (BSE), which is predictive of breastfeeding rates in mothers of preterm infants at 6 weeks postpartum.

METHODS

Family Integrated Care (FICare) integrates and supports parents to actively participate in the care of their infant while in the NICU. Nested within the broader FICare trial, we will conduct an explanatory sequential mixed methods study to investigate if FICare improves maternal BSE and rates of breastmilk feeding in moderate and late preterm infants at discharge from the NICU. In phase 1, we will calculate the mean difference between admission and discharge BSE scores for the intervention group. Mothers who score in the top and bottom 20th percentile of change scores will be invited to participate in a semi-structured telephone interview exploring maternal experiences with infant feeding in the NICU. We will conduct inductive thematic analysis to identify and describe the facilitators and barriers of FICare on maternal feeding experiences. Once data saturation is achieved and themes have been established, phase 2 will revisit the quantitative data to determine whether FICare was impactful on BSE and breastmilk feeding rates. Findings from the qualitative and quantitative phases will be integrated to determine how infant feeding experiences on FICare units work to improve or detract from maternal BSE and rates of breastmilk feeding.

DISCUSSION

FICare may help to improve maternal BSE and rates of breastmilk feeding in moderate and late preterm infants. Improved breastmilk feeding outcomes can have a substantial impact on overall infant health, developmental outcomes, and maternal-infant bonding and will help to improve long-term health outcomes for moderate and late preterm infants.

Interventions to Improve Breastfeeding Self-Efficacy and Resultant Breastfeeding Rates: A Systematic Review and Meta-Analysis

BACKGROUND

Maternal breastfeeding self-efficacy (BSE) is reflective of a mother's confidence in breastfeeding and is a modifiable factor that may improve breastfeeding rates. Breastfeeding self-efficacy theory purports that women with higher BSE will have better breastfeeding outcomes. Research aim: The aim of this systematic review was to explore the theoretical link between BSE and breastfeeding outcomes by investigating (a) if interventions to improve BSE were successful and (b) if improvements in BSE resulted in improved breastfeeding rates.

METHODS

The authors performed a systematic search of 10 databases for studies that investigated the effect of interventions for mothers of full-term infants on BSE and breastfeeding rates. They used an inverse-variance, random-effects meta-analysis.

RESULTS

Of 1,366 titles and abstracts identified, 58 full-text articles were screened and 11 met the study criteria. Compared with mothers in control groups, mothers in intervention groups had significantly higher BSE, scoring 4.86 points higher, 95% confidence interval [3.11, 6.61], at 2 months postpartum. Mothers in the intervention groups were 1.56 and 1.66 times more likely to be breastfeeding at 1 month and 2 months postpartum, respectively. Interventions that were implemented in the postpartum period, used combined delivery settings, or were informed by BSE theory had the greatest influence on breastfeeding outcomes. Meta-regression indicated that for each 1-point increase in the mean BSE score between the intervention and control groups, the odds of exclusive breastfeeding increased by 10% in the intervention group.

CONCLUSION

Breastfeeding self-efficacy is a modifiable factor that practitioners can target to improve breastfeeding rates in mothers of full-term infants.

The impact of caesarean section on breastfeeding initiation, duration and difficulties in the first four months postpartum

Background

The caesarean section (c-section) rate in Canada is 27.1 %, well above the 5–15 % of deliveries suggested by the World Health Organization in 2009. Emergency and planned c-sections may adversely affect breastfeeding initiation, milk supply and infant breastfeeding receptivity compared to vaginal deliveries. Our study examined mode of delivery and breastfeeding initiation, duration, and difficulties reported by mothers at 4 months postpartum.

Methods

The All Our Babies study is a prospective pregnancy cohort in Calgary, Alberta, that began in 2008. Participants completed questionnaires at <25 and 34–36 weeks gestation and approximately 4 months postpartum. Demographic, mental health, lifestyle, and health services data were obtained. Women giving birth to singleton infants were included (n = 3021). Breastfeeding rates and difficulties according to mode of birth (vaginal, planned c-section and emergency c-section) were compared using cross-tabulations and chi-square tests. A multivariable logistic regression model was created to examine the association between mode of birth on breastfeeding duration to 12 weeks postpartum.

Results

More women who delivered by planned c-section had no intention to breastfeed or did not initiate breastfeeding (7.4 % and 4.3 % respectively), when compared to women with vaginal births (3.4 % and 1.8 %, respectively) and emergency c-section (2.7 % and 2.5 %, respectively). Women who delivered by emergency c-section were found to have a higher proportion of breastfeeding difficulties (41 %), and used more resources before (67 %) and after (58 %) leaving the hospital, when compared to vaginal delivery (29 %, 40 %, and 52 %, respectively) or planned c-sections (33 %, 49 %, and 41 %, respectively). Women who delivered with a planned c-section were more likely (OR = 1.61; 95 % CI: 1.14, 2.26; p = 0.014) to discontinue breastfeeding before 12 weeks postpartum compared to those who delivered vaginally, controlling for income, education, parity, preterm birth, maternal physical and mental health, ethnicity and breastfeeding difficulties.

Conclusions

We found that when controlling for socio-demographic and labor and delivery characteristics, planned c-section is associated with early breastfeeding cessation. Anticipatory guidance around breastfeeding could be provided to women considering a planned c-section. As well, additional supportive care could be made available to lactating women with emergency c-sections, within the first 24 hours post birth and throughout the early postpartum period.

Efficacy and kinetics of extradural ropivacaine: comparison with bupivacaine

Ninety-one patients were allocated randomly to three groups to receive 1% ropivacaine 10 ml, 0.5% ropivacaine 20 ml or 0.5% bupivacaine 20 ml extradurally. Intermittent sensory (pinprick) and motor (Bromage scale) assessments of the block produced were recorded, with an assessment of the quality of the block and the requirement for supplementary analgesia. There was little difference between the groups in frequency, onset, duration or spread of sensory block. However, the motor block produced by 0.5% ropivacaine was less intense and of shorter duration than that with bupivacaine. The block produced by the smaller volume of ropivacaine was less reliable clinically than the larger, more dilute, solution and more anaesthetic supplements were required in that group. Cardiovascular changes were similar in all three groups. The peak plasma concentration of ropivacaine was significantly greater and T1/2 significantly shorter than those of bupivacaine, although no patient showed any features of systemic toxicity. The systemic kinetics of ropivacaine were not influenced significantly by varying the concentration or volume administered.

Complications of tracheotomy

A patient underwent elective tracheotomy before resection of the floor of the mouth. After operation, several life-threatening complications arose from this tracheotomy, including surgical emphysema of the tracheal mucosa which has not been described previously.

Comparison of extradural and intravenous diamorphine as a supplement to extradural bupivacaine

The influence of route of administration (extradural as compared with intravenous) of diamorphine 0.5 mg/hour as a supplement to extradural bupivacaine (0.125% at 15 ml/hour) was investigated in two groups of 20 patients who underwent major abdominal gynaecological surgery. Significantly more patients in the intravenous group withdrew because of inadequate analgesia (p less than 0.05). Those in the extradural group were significantly more drowsy throughout the study (p less than 0.01), but no major side effects were encountered.

The alkalinisation of bupivacaine for intercostal nerve blockade

A double-blind randomised study was performed to investigate the effect of pH adjustment of bupivacaine, with adrenaline 1:200,000, on the duration of block and pain relief after intercostal nerve blockade following thoracotomy. One group (n = 10) received bupivacaine with adrenaline 1:200,000 (pH = 4.1) and the other (n = 10) received alkalinised bupivacaine with adrenaline 1:200,000 (pH = 6.9). There was no significant difference in block duration (mean 23.9 and 26.4 hours respectively) visual analogue pain scores or morphine usage. Patients were more likely to have a block during the first 12 hours if they received alkalinised bupivacaine (p less than 0.01, Chi-squared test). A progressive regression of block, not previously described, was observed, explicable by means of spread of local anaesthesia to adjacent intercostal nerves. Alkalinisation of bupivacaine with adrenaline for intercostal nerve blockade has little clinical benefit.

A comparison of the CNS effects of enprofylline and theophylline in healthy subjects assessed by performance testing and subjective measures

1. The effects of intravenous infusions of enprofylline, theophylline, and placebo on subjective ratings and on psychological test performance were studied in a double-blind crossover experiment in 12 healthy subjects who abstained from caffeine throughout the experimental procedures. 2. Mean plasma concentrations of enprofylline were: mean 2.9 mg l-1 (range 1.9-3.4). Those for theophylline were: mean 12.1 mg l-1 (range 9.0-14.4). 3. Performance on the auditory vigilance task showed a significant improvement with theophylline compared with both enprofylline and placebo. The correct detection rates (out of 90) were 50.3, 43.4 and 39.1 respectively. A similar effect was seen with finger tapping rates: 404, 394 and 390 taps min-1 respectively. Other measures showed no significant effects, although choice reaction time showed a trend towards faster responses with theophylline. 4. Subjective ratings showed that subjects were significantly more alert with theophylline than with enprofylline. Subjects reported themselves as significantly more dizzy and ill with both active drugs compared with placebo. 5. These results suggest that emprofylline largely lacks the CNS stimulant effects of theophylline, but that the incidence of other unwanted effects of the drugs may be similar.

Alkalinisation of prilocaine for intravenous regional anaesthesia

Ten volunteers underwent intravenous regional anaesthesia on two separate occasions using 40 ml prilocaine 0.5% to which was added 5 ml of either saline 0.9% or sodium bicarbonate 8.4%. Addition of sodium bicarbonate decreased the time of onset of loss of sharp touch and temperature sensations and of motor power. Time to full recovery of the arm was slower with the alkalinized solution and nine of the subjects preferred this block. The addition of sodium bicarbonate to prilocaine for intravenous regional anaesthesia may be clinically useful.

Plasma high-density lipoprotein cholesterol and socioeconomic status. The Lipid Research Clinics Program Prevalence Study

The relationship between high-density lipoprotein (HDL) cholesterol and educational level was examined in 2182 white females and 2368 white males ages 20-59 years in nine North American populations surveyed by the Lipid Research Clinics Program. Mean HDL cholesterol values were positively associated with reported educational achievement. Among females of all ages and males ages 20-39 years, a gradient of HDL cholesterol levels from lowest to highest educational stratum was found. A similar trend of lower magnitude was noted among older males. The positive association between educational and HDL cholesterol levels was statistically significant in both sexes (p < 0.002) and was consistent for each of the study populations. Differences in mean HDL cholesterol between educational strata were in part explained statistically by education-related differences in body mass, alcohol consumption, cigarette smoking, age and, in women, gonadal hormone use. These findings indicate that socioeconomic status and lifestyle, as measured by level of educational achievement, are associated with HDL cholesterol concentrations in adult populations.
