Breastfeeding and maternal weight changes during 24 months post‐partum: a cohort study

The relationship between breastfeeding and the loss of weight gained during pregnancy remains unclear. This study aimed to investigate the association between breastfeeding and maternal weight changes during 24 months post‐partum. We studied a dynamic cohort comprising 315 women living in two cities in the state of Bahia, Brazil. The outcome variable was change in the post‐partum weight; the exposure variable was the duration and intensity of breastfeeding. Demographic, socio‐economic, environmental, reproductive and lifestyle factors were integrated in the analysis as covariates. The data were analysed using multiple linear regression and linear mixed‐effects models. The average cumulative weight loss at 6 months post‐partum was 2.561 kg (SD 4.585), increasing at 12 months (3.066 kg; SD 5.098) and decreasing at 18 months (1.993 kg; SD 5.340), being 1.353 kg (SD, 5.574) at 24 months post‐partum. After adjustment, the data indicated that for every 1‐point increase in breastfeeding score, the estimated average post‐partum weight loss observed was 0.191 kg at 6 months (P = 0.03), 0.090 kg at 12 months (P = 0.043), 0.123 kg at 18 months (P < 0.001) and 0.077 kg at 24 months (P = 0.001). Based on these results, we concluded that despite the low expressiveness, the intensity and duration of breastfeeding was associated with post‐partum weight loss at all stages of the study during the 24‐month follow‐up.     

Recruiting and retaining postpartum women from areas of social disadvantage in a weight‐loss trial – an assessment of strategies employed in the WeighWell feasibility study

Little is known about the response of post‐partum women from deprived backgrounds to weight management interventions, however behavioural intervention trials in disadvantaged communities are often characterised by recruitment difficulties. Recruitment and retention is key to the robust conduct of an effective trial, and exploratory work is essential prior to a definitive randomised controlled trial. This paper describes strategies used to recruit to the WeighWell feasibility study, which aimed to recruit 60 overweight or obese post‐partum women living in areas of deprivation to a trial of a weight‐loss intervention. Recruitment strategies included the following: (1) distribution of posters and ‘business cards’; (2) newspaper advertisements; (3) visits to community groups; and (4) personalised letters of invitation sent via the National Health Service (NHS). Potential participants were screened for eligibility following response to a Freephone number. Body mass index was calculated using self‐reported body weight and height. Over 6 months, 142 women responded of whom 65 (46%) met the eligibility criteria. The most effective methods for recruiting eligible women and those who went on to complete the study (n = 36) were visits to community groups (37% and 42%, respectively), personalised letters (26% and 17%, respectively) and posters and ‘business cards’ (22% and 31%, respectively). These results emphasise the need to utilise a range of strategies beyond traditional NHS settings. Current approaches might be enhanced by sending personal contact letters via their General Practitioner to women identified as eligible at post‐natal discharge. Under‐reporting of body weight by self‐report suggests that a threshold lower than 25 kg/m² should be utilised for screening purposes.     

Prospective associations of breastfeeding and smoking cessation among low‐income pregnant women

Although low‐income pregnant women have high rates of smoking and low rates of breastfeeding, few studies have examined prospective associations between these risk factors in community samples. Doing so may help improve breast‐feeding support programs in this population. We used a secondary analysis of 247 low‐income pregnant smokers in Memphis, Tennessee, who were interviewed up to 4 times (twice during pregnancy and twice through 6 months postpartum). Smoking cessation during prepartum and postpartum was defined as a self‐report of not smoking for ≥1 week and an expired carbon monoxide level of <10 ppm. Multivariable logistic regression analyses were used to determine whether intent to breastfeed was associated with smoking cessation and whether smoking cessation was associated with actual breastfeeding. Models were adjusted for sociodemographic, pregnancy‐related, and smoking‐related confounders. Thirty‐nine percent of participants intended to breastfeed, and 38% did so. Women who intended to breastfeed were 2 times more likely to quit smoking prepartum (adjusted OR = 1.99, 95% CI [1.06, 3.74]), but not postpartum (adjusted OR = 1.27, 95% CI [0.57, 2.84]). Quitting smoking at baseline and during pregnancy was associated with subsequent breastfeeding (adjusted OR 2.27, 95% CI [1.05, 4.94] and adjusted OR = 2.49, 95% CI [1.21, 5.11]). Low‐income women who intended to breastfeed were more likely to quit smoking during pregnancy and those who quit smoking at baseline and prepartum were more likely to breastfeed. Simultaneously supporting breastfeeding and smoking cessation may be very useful to change these important health behaviours among this high‐risk population.     

Influence of maternal and socioeconomic factors on breast milk fatty acid composition in urban,low‐income families

The lipid composition of breast milk may have a significant impact on early infant growth and cognitive development. Comprehensive breast milk data is lacking from low‐income populations in the Indian subcontinent impeding assessment of deficiencies and limiting development of maternal nutritional interventions. A single breast milk specimen was collected within 6 weeks postpartum from two low‐income maternal cohorts of exclusively breastfed infants, from Dhaka, Bangladesh (n = 683) and Kolkata, India (n = 372) and assayed for percentage composition of 26 fatty acids. Mature milk (>15 days) in Dhaka (n = 99) compared to Kolkata (n = 372) was higher in total saturated fatty acid (SFA; mean 48% vs. 44%) and disproportionately lower in ω3‐polyunsaturated fatty acid (PUFA), hence the ω6‐ and ω3‐PUFA ratio in Dhaka were almost double the value in Kolkata. In both sites, after adjusting for days of lactation, increased maternal education was associated with decreased SFA and PUFA, and increasing birth order or total pregnancies was associated with decreasing ω6‐PUFA or ω3‐PUFA by a factor of 0.95 for each birth and pregnancy. In Dhaka, household prosperity was associated with decreased SFA and PUFA and increased ω6‐ and ω3‐PUFA. Maternal height was associated with increased SFA and PUFA in Kolkata (1% increase per 1 cm), but body mass index showed no independent association with either ratio in either cohort. In summary, the socioeconomic factors of maternal education and household prosperity were associated with breast milk composition, although prosperity may only be important in higher cost of living communities. Associated maternal biological factors were height and infant birth order, but not adiposity. Further study is needed to elucidate the underlying mechanisms of these effects.     

Severe maternal morbidity and breastfeeding outcomes in the early post‐natal period: a prospective cohort study from one English maternity unit

Previous research has identified potential issues of establishing and maintaining breastfeeding among women who experience severe maternal morbidity associated with pregnancy and birth, but evidence in the UK maternity population was scarce. We explored the association between severe maternal morbidity and breastfeeding outcomes (uptake and prevalence of partial and exclusive breastfeeding) at 6 to 8 weeks post‐partum in a UK sample. Data on breastfeeding outcomes were obtained from a large cohort study of women who gave birth in one maternity unit in England to assess the impact of women's experiences of severe maternal morbidity (defined as major obstetric haemorrhage, severe hypertensive disorder or high dependency unit/intensive care unit admission) on their post‐natal health and other important outcomes including infant feeding. Results indicated that among women who responded (n = 1824, response rate = 53%), there were no statistically significant differences in breastfeeding outcomes between women who did or did not experience severe morbidity, except for women with severe hypertensive disorder who were less likely to breastfeed either partially or exclusively at 6 to 8 weeks post‐partum. Rather, breastfeeding outcomes were related to multi‐dimensional factors including sociodemographic (age, ethnicity, living arrangement), other pregnancy outcomes (neonatal intensive care unit admission, mode of birth, women's perceived control during birth) and post‐natal psychological factors (depressive symptoms). Women who experience severe maternal morbidity can be reassured that establishing successful breastfeeding can be achieved. More studies are required to understand what support is best for women who have complex health/social needs to establish breastfeeding.     

Adherence to recommendations on lipid‐based nutrient supplement and iron and folic acid tablet consumption among pregnant and lactating women participating in a community health programme in northwest Bangladesh

Limited knowledge exists on sustained adherence to small‐quantity lipid‐based nutrient supplements for pregnant and lactating women (LNS‐PL) and how this compares with that of other prenatal supplements. To address these gaps, a random subsample of women (n = 360) during pregnancy, early (6‐ to 12‐week post‐partum) and late (12‐ to 24‐week post‐partum) lactation, from an ongoing effectiveness trial in Bangladesh, was selected for in‐home interviews about LNS‐PL or iron/folic acid (IFA) use and preferences. Prevalence of high adherence (≥70% of the recommendation) based on self‐reported supplement consumption was 67%, 68% and 81% among LNS‐PL recipients during pregnancy, early and late lactation, and was 87% and 71% among IFA recipients during pregnancy and early lactation, respectively (P = 0.044). Programmatic factors (e.g. distribution and visits by programme staff) were consistently statistically significantly associated with reported high adherence. Among LNS‐PL recipients, high overall supplement acceptability score [odds ratio (OR): 8.62; 95% confidence interval (CI) 3.53, 20.83] and use of reminder techniques (OR: 4.41; 95%CI 1.65, 11.76) were positively associated, and reported vomiting at enrollment was negatively associated (OR: 0.34; 95%CI 0.14, 0.80), with reported high adherence. Selected women (n = 16) and key informants (n = 18) participated in in‐depth interviews about perceptions and acceptability of LNS‐PL. Women perceived benefits of taking LNS‐PL, but some faced barriers to consumption including aversion to odour and taste during pregnancy, forgetfulness and disruptions in supply. To achieve high adherence, results from this study suggest that maternal supplementation programmes should focus on programmatic barriers and consider incorporating reminder techniques. Organoleptic acceptability of LNS‐PL, particularly during pregnancy, may also need to be addressed.     

The effect of balanced protein energy supplementation in undernourished pregnant women and child physical growth in low‐ and middle‐income countries: a systematic review and meta‐analysis

The beneficial effect of balanced protein energy supplementation during pregnancy on subsequent child growth is unclear and may depend upon the mother entering pregnancy adequately nourished or undernourished. Systematic reviews to‐date have included studies from high‐, middle‐ and low‐income countries. However, the effect of balanced protein energy supplementation should not be generalised. This review assesses the effect of balanced protein energy supplementation in undernourished pregnant women from low‐ and middle‐income countries on child growth. A systematic review of articles published in English (1970–2015) was conducted via MEDLINE, Scopus, the Cochrane Register and hand searching. Only peer‐reviewed experimental studies analysing the effects of balanced protein energy supplementation in undernourished pregnant women from low‐ and middle‐income countries with measures of physical growth as the primary outcome were included. Two reviewers independently assessed full‐text articles against inclusion criteria. Validity of eligible studies was ascertained using the Quality Assessment Tool for Quantitative Studies (EPHPP QAT). In total, seven studies met the inclusion criteria. All studies reported on birthweight, five on birth length, three on birth head circumference, and one on longer‐term growth. Standardised mean differences were calculated using a random‐effects meta‐analysis. Balanced protein energy supplementation significantly improved birthweight (seven randomised controlled trials, n = 2367; d = 0.20, 95% confidence interval, 0.03–0.38, P = 0.02). No significant benefit was observed on birth length or birth head circumference. Impact of intervention could not be determined for longer‐term physical growth due to limited evidence. Additional research is required in low‐ and middle‐income countries to identify impacts on longer‐term infant growth.     

Transformative Lifestyle Change: key to sustainable weight loss among women in a post‐partum diet and exercise intervention

The increase in overweight and obesity among women is a growing concern, and reproduction is associated with persistent weight gain. We have shown that dietary behavioural modification treatment, with or without exercise, results in weight loss and maintenance of weight loss. The aim of this study was to provide an explanatory model of how overweight and obese women achieve weight loss during, and after, participating in a post‐partum diet and/or exercise intervention. Using Grounded Theory, we performed and analysed 29 interviews with 21 women in a 12‐week Swedish post‐partum lifestyle intervention with a 9‐month follow‐up. Interviews were made after the intervention and at the 9‐month follow‐up. To overcome initial barriers to weight loss, the women needed a ‘Catalytic Interaction’ (CI) from the care provider. It depended on individualised, concrete, specific and useful information, and an emotional bond through joint commitment, trust and accountability. Weight loss was underpinned by gradual introduction of conventional health behaviours. However, the implementation depended on the experience of the core category process ‘Transformative Lifestyle Change’ (TLC). This developed through a transformative process of reciprocal changes in cognitions, emotions, body, environment, behaviours and perceived self. Women accomplishing the stages of the TLC process were successful in weight loss, in contrast to those who did not. The TLC process, dependent on initiation through CI, led to implementation and integration of recognised health behaviours, resulting in sustainable weight loss. The TLC model, including the CI construct and definition of barriers, facilitators and strategies provides an explanatory model of this process.     

Effect of a low glycaemic index diet in gestational diabetes mellitus on post‐natal outcomes after 3 months of birth: a pilot follow‐up study

A low glycaemic index (LGI) diet during pregnancy complicated by gestational diabetes mellitus (GDM) may offer benefits to the mother and infant pair beyond those during pregnancy. We aimed to investigate the effect of an LGI diet during pregnancy complicated with GDM on early post‐natal outcomes. Fifty‐eight women (age: 23–41 years; mean ± SD pre‐pregnancy body mass index: 24.5 ± 5.6 kg m^?2) who had GDM and followed either an LGI diet (n = 33) or a conventional high‐fibre diet (HF; n = 25) during pregnancy had a 75‐g oral glucose tolerance test and blood lipid tests at 3 months post‐partum. Anthropometric assessments were conducted for 55 mother–infant pairs. The glycaemic index of the antenatal diets differed modestly (mean ± SD: 46.8 ± 5.4 vs. 52.4 ± 4.4; P < 0.001), but there were no significant differences in any of the post‐natal outcomes. In conclusion, an LGI diet during pregnancy complicated by GDM has outcomes similar to those of a conventional healthy diet. Adequately powered studies should explore the potential beneficial effects of LGI diet on risk factors for chronic disease.     

Effectiveness of breastfeeding interventions delivered to fathers in low‐ and middle‐income countries: A systematic review

Adequate support for lactating mothers is crucial to improve the rates of early initiation, exclusive, and continued breastfeeding. Maternal breastfeeding intention and ongoing breastfeeding duration are strongly predicted by their partners' breastfeeding beliefs. Partner support has a significant effect on improving rates of any and exclusive breastfeeding, when compared with professional support, particularly in low‐income populations. This systematic review investigates the effectiveness of breastfeeding interventions targeting fathers in low‐ and middle‐income countries (LMIC). A systematic literature search was undertaken on Medline (EBSCOhost), PsycInfo, CINAHL, and Scopus databases and via manual searching. Inclusion criteria were experimental or quasiexperimental designs targeting fathers from LMIC, which measured either breastfeeding initiation, breastfeeding exclusivity, or duration of breastfeeding as the main outcomes. No time restriction was put in place, and all articles were published in English. The quality of selected papers was assessed using the Joanna Briggs Institute tool. A total of 8 articles were included from 6 interventions: 2 quasiexperimental and 4 randomized control trials. All interventions involved breastfeeding education targeting fathers; 2 were given only to fathers, and 4 delivered to both fathers and mothers. Among these interventions, 2 measured both early initiation and exclusive breastfeeding; one exclusive breastfeeding only; one exclusive breastfeeding, knowledge, and attitudes; one exclusive breastfeeding and knowledge; and one breastfeeding, continued breastfeeding, and awareness. Across all interventions, breastfeeding education showed significant improvement in breastfeeding outcomes in the intervention compared with the control groups. In summary, breastfeeding education interventions targeting fathers in LMIC are effective in improving early initiation of breastfeeding, exclusive breastfeeding, and continued breastfeeding. Thus, breastfeeding promotion should consider the education and involvement of fathers in the intervention.     

Incidence of necrotizing enterocolitis in very‐low‐birth‐weight infants related to the use of Lactobacillus GG

Background: One of the five level III neonatal intensive care units (NICU) in Finland has used prophylactic Lactobacillus GG (LGG) for very‐low‐birth‐weight (VLBW) infants since 1997. Aim: To examine retrospectively the incidence of necrotizing enterocolitis (NEC) in all five university hospital NICUs in Finland in relation to the use of LGG during the years each unit has belonged to the Vermont Oxford Network (VON). Methods: The incidence of NEC was analysed from the national database and from the VON databases separately in all five level III NICUs and additionally in three groups according to the probiotic practice in the hospitals: prophylactic LGG group, probiotics ‘on demand’ group and no probiotics group. Results: The incidence of NEC was 4.6% vs. 3.3% vs. 1.8% in the prophylactic LGG group, the probiotics ‘on demand’ group and the no probiotics group, respectively; p = 0.0090, chi‐square. LGG had no influence on the clinical course of NEC. Conclusions: The results of this retrospective report failed to show that LGG prophylaxis protects VLBW infants from the occurrence of NEC, in contrast to previously published results. Our results call for more research regarding effective ways to administer probiotics, including data on appropriate bacteria, strain, dose and timing of administration to achieve clinically robust effects.     

SIOP PODC: Recommendations for supportive care of children with cancer in a low‐income setting

These supportive care recommendations were prepared to guide doctors who practice in areas with significantly limited resources but who have sufficient infrastructure and training to treat children with cancer with curative intent. The success of any cancer treatment regimen depends largely on the availability and quality of supportive care and this also determines the intensity of treatment that can be delivered. We present practical recommendations on how to prevent infections, general nursing care, management of febrile neutropenia, nutritional assessment and support, treatment of co‐infections and the social support to help prevent failure to complete treatment in resource poor settings.

Addressing barriers to maternal nutrition in low‐ and middle‐income countries: A review of the evidence and programme implications

Adequate maternal nutrition during the “first 1,000 days” window is critical from conception through the first 6 months of life to improve nutritional status and reduce the risk of poor birth outcomes, such as low birthweight and preterm birth. Unfortunately, many programmes have targeted implementation and monitoring of nutrition interventions to infants and young children, rather than to women during pregnancy or post‐partum. A literature review was conducted to identify barriers to food choice and consumption during pregnancy and lactation and to examine how low‐ and middle‐income countries have addressed maternal nutrition in programmes. A literature review of peer‐reviewed and grey literature was conducted, and titles and abstracts reviewed by authors. Twenty‐three studies were included in this review. Barriers to adequate nutrition during pregnancy included cultural beliefs related to knowledge of quantity of food to eat during pregnancy, amount of weight to gain during pregnancy, and “eating down” during pregnancy for fear of delivering a large baby. Foods considered inappropriate for consumption during pregnancy or lactation contributed to food restriction. Drivers of food choice were influenced by food aversions, economic constraints, and household food availability. Counselling on maternal diet and weight gain during pregnancy was seldom carried out. Programming to support healthy maternal diet and gestational weight gain during pregnancy is scant. Tailored, culturally resonant nutrition education and counselling on diet during pregnancy and lactation and weight gain during pregnancy, as well as monitoring of progress in maternal nutrition, are areas of needed attention.     

Probiotics for the prevention of necrotising enterocolitis in very low‐birth‐weight infants: a meta‐analysis and systematic review

We performed an updated meta‐analysis incorporating the results of recent randomised controlled trials (RCTs) to measure the effectiveness of probiotic supplementation in preventing necrotising enterocolitis (NEC) and death in very low‐birth‐weight (VLBW) infants, and to investigate any differences in efficacy by probiotic agent. Using meta‐regression analysis, we assessed the contribution of other measured variables on the overall effect size and between‐study variability. Conclusion: Overall, probiotics lead to significant reductions in NEC incidence and mortality in VLBW infants. Differences in probiotic agents and the influence of prenatal steroids and feeding regimens may explain the differences in outcomes between studies.     

A qualitative study exploring midwives' perceptions and knowledge of maternal obesity: Reflecting on their experiences of providing healthy eating and weight management advice to pregnant women

Midwives are responsible for providing advice regarding the complex issues of healthy eating and weight management during pregnancy. This study utilised an inductive data‐driven thematic approach in order to determine midwives' perceptions, knowledge, and experiences of providing healthy eating and weight management advice to pregnant women. Semistructured interviews with 17 midwives were transcribed verbatim and data subjected to thematic analysis. The findings offer insight into the challenges facing midwives in their role trying to promote healthy eating and appropriate weight management to pregnant women. Three core themes were identified: (a) “If they eat healthily it will bring their weight down”: Midwives Misunderstood; (b) “I don't think we are experienced enough”: Midwives Lack Resources and Expertise; and (c) “BMI of 32 wouldn't bother me”: Midwives Normalised Obesity. The midwives recognised the importance of providing healthy eating advice to pregnant women and the health risks associated with poor diet and obesity. However, they reported the normalisation of obesity in pregnant women and suggested that this, together with their high workload and lack of expertise, explained the reasons why systematic advice was not in standard antenatal care. In addition, the current lack of UK clinical guidance, and thus, possibly lack of clinical leadership are also preventing delivery of tailored advice. Implementation literature on understanding the barriers to optimal health care delivery and informing clinical practice through research evidence needs to be further investigated in this field. This study has recommendations for policy makers, commissioners, service providers, and midwives.     

A case–control study to examine the association between breastfeeding during late pregnancy and risk of a small‐for‐gestational‐age birth in Lima,Peru

Excessive demands on maternal nutritional status may be a risk factor for poor birth outcomes. This study examined the association between breastfeeding during late pregnancy (≥28 weeks) and the risk of having a small‐for‐gestational‐age (SGA) newborn, using a matched case–control design (78 SGA cases: birthweight <10th percentile for gestational age; 150 non‐SGA controls: 50th percentile <birthweight <90th percentile for gestational age). Between March 2006 and April 2007, project midwives visited daily three government hospitals in Lima, Peru and identified cases and matched controls based on hospital, gestational age, and inter‐gestational period. Mothers were interviewed and clinical chart extractions were completed. Factors associated with risk of SGA were assessed by their adjusted odds ratios (aOR) from conditional logistic regression. Exposure to an overlap of breastfeeding during late pregnancy was not associated with an increased risk of having a SGA newborn [aOR = 0.58, 95% confidence interval (CI): 0.10–3.30]. However, increased risk was associated with having a previous low‐birthweight birth (aOR = 6.53; 95% CI: 1.43–29.70) and a low intake of animal source foods (<25th percentile; aOR = 2.26; 95% CI: 1.01–5.04), and tended to be associated with being short (<150 cm; aOR = 2.05; 95% CI: 0.92–4.54). This study found no evidence to support the hypothesis that breastfeeding during late pregnancy increases the risk for SGA; however, studies with greater statistical power are needed to definitively examine this possible association and clarify whether there are other risks to the new baby, the toddler and the pregnant woman.
