RESUMO

BACKGROUND: Weight retention between pregnancies is associated with increased risk of perinatal complications, but it is unclear whether there is an association with offspring weight status. This study aimed to determine whether maternal interpregnancy weight change is associated with offspring overweight/obesity, controlling for confounding variables. SUBJECTS/METHODS: Routinely collected linked data from perinatal and child datasets, in Flanders, Belgium were used. Women having their first and second live births between 2009-2018 were included. The association between maternal interpregnancy weight change and overweight/obesity in the second child at 2 years was examined by logistical regression models. RESULTS: A total of 33,172 women were included. 52.7% (n = 17478) had a stable interpregnancy BMI, 24.1% (n = 8024) and 8.5% (n = 2821) had moderate and substantial BMI increases respectively. At 2 years, 91.6% (n = 30383) of the second offspring had a healthy weight, 0.6% (n = 210), 7.0% (n = 2312) and 0.8% (n = 267) were in the underweight, overweight and obesity BMI categories respectively. Multivariate analysis showed no statistical evidence that maternal interpregnancy BMI change is independently associated with overweight/obesity in the second child. The strongest independent factors were the first child (sibling) being in the obesity category at 2 years (odds ratio [OR] 7.2, [95% CI, 5.49-9.45] and being born Large for Gestational Age (LGA) (2.13 [1.92-2.37]). The following variables were also independently associated with the outcome measure: maternal African origin (1.90 [1.59-2.26]), maternal obesity at start of first pregnancy (1.33 [1.16-1.53]), excessive gestational weight gain in the second pregnancy (1.15 [1.04-1.28]), being born after a < 1-year interpregnancy time interval (1.17 [1.05-1.30]) and not being exclusively breastfed at 12 weeks old (1.29 [1.10-1.52]). CONCLUSION: Sibling obesity and being born LGA were most strongly independently associated with overweight/obesity at 2 years. This supports the need for family interventions and to address risk factors for development of LGA infants. There was no independent association with interpregnancy weight gain, contrary to what was hypothesised.

RESUMO

BACKGROUND: The Manual of dietetic practice ('Manual') is the core textbook for qualified and student dietitians. A survey was conducted to explore views on the scope, content and presentation of the Manual to inform the forthcoming edition. METHODS: The survey comprised of questions on demographics, structure, content, access (print/digital), missing topics, strengths and weaknesses. It was distributed to members of the British Dietetic Association (BDA) and other relevant groups in August 2022. Responses are presented as frequencies and free text as themes. RESULTS: Of 1179 responses, 91% were from professionals, of whom 72% were registered dietitians with a mean of 12.7 years (range: 1-44) in practice: 60% worked in the United Kingdom with 52% based in a clinical setting. The printed version was preferred: 59% professionals, 60% students, 94% professionals and 88% students were satisfied with the structure; however, 26% professionals and 22% students identified content that was lacking or outdated, including mental health and sustainability. The strengths were its comprehensive coverage and respected contributing authors. Weaknesses included the cost, size, lack of visual aids and currency. Professionals indicated the seventh edition should focus on more practical information required for clinical practice, whereas students wanted more emphasis on summarised information and visual formats. CONCLUSIONS: The survey proved a valuable method to engage with the readership to ensure the next edition reflected their requirements. Although nearly all respondents were satisfied with the scope and content, the results highlighted those topics lacking and/or outdated. Results also showed that the next edition should focus on practical information required for clinical practice, with more summarised and visual formats.

RESUMO

BACKGROUND: Hyperemesis gravidarum (HG) is severe pregnancy sickness, often leading to dehydration, weight loss and electrolyte disturbances. Little is known about nutritional intake and its consequences in those affected. The aim of this study was to explore the first trimester nutritional intake and clinical characteristics in those with severe sickness. METHOD: Recruitment was via the social media accounts of national pregnancy charities. The eligibility criteria were as follows: between 6 and 11 weeks pregnant, age ≥18 years and residing in the UK. Participants completed a self-report online questionnaire including the Pregnancy Unique Quantification of Emesis 24 (PUQE24) score and a 3-day online diet diary. Groups were compared by PUQE24 categories. Nutritional intakes were compared to dietary reference values. RESULTS: One hundred sixty-six participants took part in the study: 36 categorised with mild, 109 with moderate and 21 with severe symptoms at a median gestation of 8.1 (interquartile range [IQR] 3) weeks. Those in the severe category had significantly higher weight loss (3.0 kg, IQR 3.5) than the mild category (0.0 kg, IQR 0.9). In those who completed the diet diary (n = 70), intakes of energy, carbohydrate, protein, fat, fibre, calcium, iron, zinc, thiamine, riboflavin, folate and vitamin C were all significantly lower in the severe category (p < 0.05). The severe group consumed only 39.5% and 41.6% of energy and protein needs, respectively, and were more likely to stop taking micronutrient supplements (p < 0.05). CONCLUSION: Nutritional and supplement intake in those with severe pregnancy sickness was poor; however, intake across all participants was suboptimal. Future research should investigate how to improve nutritional intake across all categories of pregnancy sickness.

RESUMO

BACKGROUND: Endometriosis is a common condition causing chronic pain, fatigue and gut symptoms. Research suggests that dietary changes may improve symptoms; however, evidence is lacking. The present study aimed to investigate the nutritional practices and needs of individuals with endometriosis (IWE) and the management of endometriosis by dietitians in the UK, focusing on gut symptoms. METHODS: Two online questionnaires were distributed via social media: a survey of dietitians working with IWE and functional gut symptoms and a survey of IWE. RESULTS: All respondents to the dietitian survey (n = 21) used the low fermentable oligosaccharides disaccharides monosaccharides and polyols (FODMAP) diet in IWE, with the majority 69.3% (n = 14), reporting positive adherence and patient benefit. Dietitians recommended more training (85.7%, n = 18) and resources (81%, n = 17) for IWE. Of those who completed the IWE questionnaire (n = 1385), 38.5% (n = 533) had coexisting irritable bowel syndrome. Only 24.1% (n = 330) had satisfactory relief of gut symptoms. The most common symptoms were tiredness, bloating and abdominal pain, experienced by 85.5% (n = 1163), 75.3% (n = 1025) and 67.3% (n = 917), respectively. Some 52.2% (n = 723) had tried dietary modifications to relieve their gut symptoms; 36.7% (n = 500) ate a restricted diet at present; 13.5% (n = 184) experienced recent unintentional weight loss and 29.8% (n = 407) a decreased appetite Some 13.2% (n = 183) had seen a dietitian regarding their gut symptoms. Of those who had not seen a dietitian, 57.7% (n = 693) would find it useful to. CONCLUSIONS: Gut symptoms and dietary restriction are very common in IWE; however, dietetic input is not. More research on the role of nutrition and dietetics in the management of endometriosis is recommended.

RESUMO

The COVID-19 lockdown had a series of intended and unintended consequences, including reduced infections and changes in activities and behaviours. Some of these changes may have been beneficial to perinatal outcomes; however, other factors such as reduced access to face-to-face healthcare may have contributed negatively to antenatal care. The aim of this audit was to evaluate neonatal admissions in the South-West of England during the COVID-19 pandemic in 2020 and the previous two years 2018-2019. Anonymised birth and neonatal admission rates from January to December 2020 was obtained and compared to data from 2018 to 2019. The results demonstrate a decreasing in neonatal unit admissions between 2018 and 2020, 9.48% of live births in 2018 (95% CI 9.17, 9.80) to 8.89% (95% CI 8.65, 9.13) in 2020 (p = 0.002).Conclusion: There were no significant differences across gestational groups. It is unclear without nationwide data whether our observed trends, decreased neonatal admissions over the past 3 years, are generalisable and related to the COVID-19 pandemic. Future research exploring the impact of lockdowns on behaviour change during pregnancy and support services is warranted to understand the implications of pandemics on pregnancy and preterm birth. What is Known: • The COVID-19 lockdown had a series of intended and unintended consequences; some of which may have been beneficial to perinatal outcomes. • Research suggests that preterm births have not significantly changed overall, but they have decreased in high-income countries. What is New: • In our audit, analysing retrospective data of regional birth and neonatal admission from the South-West of England, we observed a decrease in live birth rates between 2018 and 2020. • A reduction in neonatal unit admissions was observed from 2018 to 2020 with no significant differences across gestational groups. The reduction from 2019 to 2020 was smaller than that from 2018 to 2019 implying that the COVID-19 pandemic in 2020 was not necessarily implicated.

RESUMO

Hyperemesis gravidarum (HG) is a condition at the extreme end of the pregnancy sickness spectrum, estimated to affect 1-2 % of pregnant women. This narrative review provides an overview of the current literature concerning the nutritional implications and management of HG. HG can persist throughout pregnancy, causing malnutrition, dehydration, electrolyte imbalance and unintended weight loss, requiring hospital admission in most cases. In addition to its negative effect on maternal, physical and psychological wellbeing, HG can negatively impact fetal growth and may have adverse consequences on the health of the offspring. HG care and research have been hampered in the past due to stigma, inconsistent diagnostic criteria, mismanagement and lack of investment. Little is known about the nutritional intake of women with HG and whether poor intake at critical stages of pregnancy is associated with perinatal outcomes. Effective treatment requires a combination of medical interventions, lifestyle changes, dietary changes, supportive care and patient education. There is, however, limited evidence-based research on the effectiveness of dietary approaches. Enteral tube feeding and parenteral nutrition are generally reserved for the most intractable cases, where other treatment modalities have failed. Wernicke encephalopathy is a rare but very serious and avoidable consequence of unmanaged HG. A recent priority-setting exercise involving patients, clinicians and researchers highlighted the importance of nutrition research to all. Future research should focus on these priorities to better understand the nutritional implications of HG. Ultimately improved recognition and management of malnutrition in HG is required to prevent complications and optimise nutritional care.

RESUMO

BACKGROUND: Associations have been shown between concurrent assessment of dietary intake of advanced glycation end products (AGEs) and childhood allergic outcomes. We examined the association between maternal AGEs intake and development of offspring asthma, wheeze, atopic dermatitis, allergic rhinitis and food allergies, and sought to determine whether the intake of AGEs was associated with cord sera cytokines/chemokines. METHODS: Pregnant women ≥16 years were recruited in the Healthy Start study, a prospective pre-birth cohort from Colorado (N = 1410). The analysis included 962 dyads with adequate diet (≥2 recalls) and allergy outcome details. AGEs intake was estimated for each mother by matching intakes reported using 24-h dietary recalls during pregnancy to a reference database of commonly consumed foods' AGEs values. Child diagnoses of asthma and allergies up to 8 years were obtained from electronic medical records. Cord sera cytokines and chemokines were analysed in a subset (N = 462) of children. RESULTS: The median [IQR] AGEs intake for the overall sample was 11,919 kU/day [8293, 16,573]. Unadjusted analysis showed a positive association between maternal AGEs intake in pregnancy and rhinitis up to 8 years of age (HR = 1.03; 95% CI: 1.01, 1.06), but the association was attenuated and no longer significant in adjusted models (HR = 1.01; 95% CI: 0.98, 1.04). Both adjusted and unadjusted models showed no associations between AGEs intake in pregnancy and any of the other outcomes (p > .05). There were no significant associations between any cytokine or chemokine measured and AGEs intake or any of the outcomes studied (p > .05). CONCLUSION: The study showed that maternal AGEs intake was not associated with offspring asthma and allergy outcomes. AGEs exposure during pregnancy may not have the same impact on child development as postnatal exposure.

RESUMO

BACKGROUND: Breast milk is the feed of choice for premature infants, although its nutritional composition is not always sufficient to meet their raised nutritional requirements. The addition of a multi-nutrient breast milk fortifier (BMF) to breastmilk is recommended; however, international guidelines on the use of BMF are inconsistent. The present study aimed to explore the use of BMF in preterm infants by paediatric dietitians in the UK. METHODS: A questionnaire was designed and sent to members of the British Dietetic Association neonatal specialist group (n = 100) using a secure online platform. Descriptive statistics were calculated. RESULTS: Forty dietitians completed the survey, all of whom used BMF. Local hospital BMF guidelines were available to 77.5% (n = 31). The most commonly used criteria for commencing BMF were: tolerating a feed volume of 150 mL kg-1  day-1 (72.5%, n = 29), a gestational age <34 weeks (67.5%, n = 27) and a birth weight <1500 g (60%, n = 24). The primary contraindication for the use of BMF was necrotising enterocolitis (NEC). The majority of respondents used standard fortification, with individualised fortification available to only 12.5% (n = 5). The most common indicators for discontinuing BMF were on discharge home (67.5%, n = 27), satisfactory growth (65%, n = 26) or feeding directly from the breast (62.5%, n = 25). CONCLUSIONS: Although BMF is used more proactively in UK neonatal units than previously, variation in practice remains. Individualised fortification is very uncommon and caution remains regarding risk of NEC. The development of national guidelines on the use of BMF would help to standardise nutritional care in neonatal units.

RESUMO

To fully understand the role of diet diversity on allergy outcomes and to set standards for conducting research in this field, the European Academy of Allergy and Clinical Immunology Task Force on Diet and Immunomodulation has systematically explored the association between diet diversity and allergy outcomes. In addition, a detailed narrative review of information on diet quality and diet patterns as they pertain to allergic outcomes is presented. Overall, we recommend that infants of any risk category for allergic disease should have a diverse diet, given no evidence of harm and some potential association of benefit in the prevention of particular allergic outcomes. In order to harmonize methods for future data collection and reporting, the task force members propose relevant definitions and important factors for consideration, when measuring diet diversity in the context of allergy. Consensus was achieved on practice points through the Delphi method. It is hoped that the definitions and considerations described herein will also enable better comparison of future studies and improve mechanistic studies and pathway analysis to understand how diet diversity modulates allergic outcomes.

RESUMO

RATIONALE: Allergic diseases are an increasing public health concern, and early life environment is critical to immune development. Maternal diet during pregnancy has been linked to offspring allergy risk. In turn, maternal diet is a potentially modifiable factor, which could be targeted as an allergy prevention strategy. In this systematic review, we focused on non-allergen-specific modifying factors of the maternal diet in pregnancy on allergy outcomes in their offspring. METHODS: We undertook a systematic review of studies investigating the association between maternal diet during pregnancy and allergic outcomes (asthma/wheeze, hay fever/allergic rhinitis/seasonal allergies, eczema/atopic dermatitis (AD), food allergies, and allergic sensitization) in offspring. Studies evaluating the effect of food allergen intake were excluded. We searched three bibliographic databases (MEDLINE, EMBASE, and Web of Science) through February 26, 2019. Evidence was critically appraised using modified versions of the Cochrane Collaboration Risk of Bias tool for intervention trials and the National Institute for Clinical Excellence methodological checklist for cohort and case-control studies and meta-analysis performed from RCTs. RESULTS: We identified 95 papers: 17 RCTs and 78 observational (case-control, cross-sectional, and cohort) studies. Observational studies varied in design and dietary intakes and often had contradictory findings. Based on our meta-analysis, RCTs showed that vitamin D supplementation (OR: 0.72; 95% CI: 0.56-0.92) is associated with a reduced risk of wheeze/asthma. A positive trend for omega-3 fatty acids was observed for asthma/wheeze, but this did not reach statistical significance (OR: 0.70; 95% CI: 0.45-1.08). Omega-3 supplementation was also associated with a non-significant decreased risk of allergic rhinitis (OR: 0.76; 95% CI: 0.56-1.04). Neither vitamin D nor omega-3 fatty acids were associated with an altered risk of AD or food allergy. CONCLUSIONS: Prenatal supplementation with vitamin D may have beneficial effects for prevention of asthma. Additional nutritional factors seem to be required for modulating the risk of skin and gastrointestinal outcomes. We found no consistent evidence regarding other dietary factors, perhaps due to differences in study design and host features that were not considered. While confirmatory studies are required, there is also a need for performing RCTs beyond single nutrients/foods.

RESUMO

The prevalence of allergic diseases such as allergic rhinitis, asthma, food allergy, and atopic dermatitis has increased dramatically during the last decades, which is associated with altered environmental exposures and lifestyle practices. The purpose of this review was to highlight the potential role for dietary fatty acids, in the prevention and management of these disorders. In addition to their nutritive value, fatty acids have important immunoregulatory effects. Fatty acid-associated biological mechanisms, human epidemiology, and intervention studies are summarized in this review. The influence of genetics and the microbiome on fatty acid metabolism is also discussed. Despite critical gaps in our current knowledge, it is increasingly apparent that dietary intake of fatty acids may influence the development of inflammatory and tolerogenic immune responses. However, the lack of standardized formats (ie, food versus supplement) and standardized doses, and frequently a lack of prestudy serum fatty acid level assessments in clinical studies significantly limit our ability to compare allergy outcomes across studies and to provide clear recommendations at this time. Future studies must address these limitations and individualized medical approaches should consider the inclusion of specific dietary factors for the prevention and management of asthma, food allergy, and atopic dermatitis.

RESUMO

BACKGROUND: Cows 'milk protein allergy (CMPA) is the most common food allergy in infants in the United Kingdom. Infants with CMPA who are not exclusively breastfed require a substitute hypoallergenic formula, which are perceived as having a poor palatability. This study compares the palatability of different extensively hydrolysed formulas (EHFs) and explores healthcare professional (HCP) expectations of how palatability impacts infants and their families. METHODS: Healthcare professional with experience of CMPA were recruited to take part in a home palatability test of four EHFs [Aptamil Pepti 1, Nutricia Ltd. (EHF W1); Althera, Nestle Health Science (EHF W2); Similac Alimentum, Abbott (EHF C1); Nutramigen LGG 1, Mead Johnson (EHF C2)] using a blind taste procedure. A randomised, complete block design was used to minimise order and carry-over biases. Participants completed a questionnaire about the impact of formula palatability on infants and their families. RESULTS: A total of 100 HCPs took part (51 dietitians and 49 general practitioners). Overall, whey-based lactose-containing EHFs were ranked the most palatable: EHF W1 by 77% of participants and EHF W2 by 20%. EHF W1 was liked significantly more (P < 0.0001) than the other formulas. The vast majority of participants agreed that better palatability would result in an increased chance of non-rejection (96%), more content families (92%) and decreased healthcare costs (90%). CONCLUSION: Amongst HCPs who manage infants with CMPA, whey-based lactose-containing EHFs were ranked the most palatable. HCPs expected that good palatability would result in better acceptance, more content infants and families, alongside decreased wastage and healthcare costs.

RESUMO

As the prevalence of allergic disease dramatically rises worldwide, prevention strategies are increasingly being considered. Given the potential modulatory effect of nutritional factors on disease, altering maternal diet during pregnancy and/or lactation has been considered in preventing allergic disease in offspring. Although there are a number of observational studies that have examined possible associations between maternal diet and allergic outcomes in offspring, interventional trials are limited. Furthermore, there is a paucity of studies that have prospectively studied maternal dietary intake as well as measuring maternal and infant biologic samples (blood, urine, breast milk) and their relation to allergic outcomes in infants. There is also a particular need to define terminology such as 'fruit and vegetables intake', 'healthy diet', and 'diet diversity' in order to make studies comparable. In this review, we discuss current evidence of maternal dietary factors during pregnancy and/or lactation that may play a role in the offspring developing allergic disease, including factors such as overall dietary intake patterns, specific whole food consumption (fish, fruit and vegetables, and common allergic foods), and individual immunomodulatory nutrient intakes. Additionally, we discuss the limitations of previous studies and propose improvements to study design for future investigation.

RESUMO

Nutritional intake during infancy is a critical aspect of child development and health that is of significant public health concern. Although there is extensive research on breast-feeding and timing of solid food introduction, there is less evidence on types of solid foods fed to infants, specifically commercially prepared infant foods. The consumption of commercially prepared infant foods is very prevalent in many developed countries, exceeding the consumption of homemade foods in some situations. Although these food products may have practical advantages, there are concerns about their nutritional composition, sweet taste, bioavailability of micronutrients, diversity of ingredients and long-term health effects. The extent that the manufacturing, fortification and promotion of these products are regulated by legislation varies between countries and regions. The aim of the present narrative review is to investigate, appraise and summarise these aspects. Overall there are very few studies directly comparing homemade and commercial infant foods and a lack of longitudinal studies to draw firm conclusions on whether commercial infant foods are mostly beneficial or unfavourable to infant health.

RESUMO

BACKGROUND: Dietary variety is defined as the number of different foods or food groups consumed over a given reference period, the consensus being that dietary variety and dietary quality are positively correlated. Recently there has been considerable interest in the association between infant dietary variety and atopic disease. METHODS: This was a cross-sectional study of 8- to 27-month-old children from the Isle of Wight, UK, including two groups: a group of children consuming a cows' milk exclusion (CME) diet and a control group of children consuming an unrestricted diet. Parents completed a validated food frequency questionnaire, from which dietary variety and consumption of food groups were calculated. Growth measurements were recorded. RESULTS: A total of 126 participants of mean age 13.0 months were recruited. In addition to the expected differences in dairy and soya consumption, the CME group consumed sweet foods 1.6 times less frequently, non-water drinks seven times less frequently (p < 0.05) and ready-made baby foods 15 times more frequently (p < 0.01) than the control group. Overall dietary variety was significantly lower in the CME group (p < 0.01) as was variety of meat and sweet foods consumed. There was a greater concern with healthy eating in the CME group (p < 0.05). CONCLUSIONS: Children consuming an exclusion diet for cows' milk allergy have an overall less varied diet, including a less varied consumption of meat and sweet foods. Efforts should be made to ensure exclusion diets are as varied as possible to optimize nutritional intake.

RESUMO

BACKGROUND: The aim of this study was to explore the natural history of peanut allergy in childhood in two birth cohorts from the same geographical region in the South of England. METHODS: The FAIR birth cohort was established on the Isle of Wight (UK) between 2001 and 2002 (n = 969). Children were followed up prospectively, skin prick tested (SPT) to peanut allergens at 1, 2, 3 and 10 years and food challenges performed. The Isle of Wight (IOW) birth cohort was established in 1989 (n = 1456). SPTs were performed at 1, 2, 4 and 10 years. Peanut allergy was based on positive SPT and a good clinical history. RESULTS: In the FAIR cohort, the prevalence of sensitization to peanut was 0.4%, 2.0%, 2.0% and 2.4% at 1, 2, 3 and 10 years, respectively. At 10 years of age, 12 of 828 (1.5%) children were diagnosed with peanut allergy. One child (8%) outgrew her peanut allergy between 3 and 10 years and two children (15%) presented with new onset peanut allergy. Over the first 10 years of life, 13 of 934 (1.4%) children were diagnosed with peanut allergy. In the IOW cohort, 6 of 1034 (0.58%) were diagnosed with peanut allergy at 10 years. We found no significant differences between the FAIR and the IOW birth cohort for any of the time points studied. CONCLUSION: Peanut allergy appears to be stable over the first 10 years of life in our cohorts. There was no significant difference in peanut sensitization or clinical peanut allergy between 1989 and 2001.

RESUMO

BACKGROUND: Dietary restriction during infancy may influence later eating behaviour. The aim of this study was to determine whether consuming a cows' milk exclusion (CME) diet during infancy affects eating habits in later childhood, once cows' milk has been reintroduced into the diet. METHODS: Children were recruited from two large birth cohort studies in the UK. A small number of participants were recruited from allergy clinic. Two groups were recruited: an experimental group of children who had consumed a CME diet during infancy and a control group, who had consumed an unrestricted diet during infancy. Parents and children completed questionnaires regarding eating behaviour and food preferences. RESULTS: In total, 101 children of mean age 11.5 years were recruited (28 CME and 73 controls). The CME group scored significantly higher on 'slowness of eating' and on the combined 'avoidant eating behaviour' construct (p < 0.01). The number of foods avoided and symptoms was associated with higher levels of avoidant eating behaviour (p < 0.05). The CME group rated liking for several dairy foods (butter, cream, chocolate, full fat milk and ice cream) significantly lower than the control group (p < 0.05), although there were no significant differences seen for any other category of food. CONCLUSION: This study demonstrated that consuming a CME diet during infancy has persistent and long-term effects on eating habits and food preferences. To reduce future negative eating behaviours, children's exclusion diets need to be as varied as possible and reintroduction of cows' milk products closely monitored.

RESUMO

The dual burden of malnutrition is characterised by the coexistence of undernutrition alongside overweight/obesity and diet-related noncommunicable diseases. It is a paradox which disproportionately affects women and is applicable to those who become pregnant after weight loss surgery. Obesity before and during pregnancy is associated with increased risk of adverse perinatal outcomes in both mother and child. Overall lifestyle interventions targeting weight loss in the preconception period have not proven effective, with people, and women in particular, increasingly seeking weight loss surgery. In women with severe obesity, surgery may normalise hormonal abnormalities and improve fertility. In those who become pregnant after surgery, evidence suggests a better overall obstetric outcome compared to those with severe obesity managed conservatively; however, there is heightened risk of maternal nutritional deficiencies and infants born small for gestational age. Specifically, pregnancy soon after surgery, in the catabolic phase when rapid weight loss is occurring, has the potential for poor outcomes. Lifelong micronutrient supplementation is required, and there is considerable risk of malnutrition if nutritional aftercare guidelines are not adhered to. It is therefore recommended that pregnancy is delayed until a stable weight is achieved and is supported by individualised advice from a multidisciplinary team. Further research is required to better understand how weight loss surgery affects the chances of having a healthy pregnancy and to ultimately improve nutritional management and patient care. In this review, we aim to summarise the evidence and guidance around nutrition during pregnancy after weight loss surgery.

RESUMO

Pregnancy during or soon after treatment with weight loss medication, particularly glucagon-like peptide-1 receptor agonists (GLP-1 RAs), is contraindicated due to potential teratogenicity. The aim of this scoping review is to investigate what is known about the use of weight loss medication in women of childbearing age in relation to reproductive health outcomes, focusing on the three medications licenced in the United Kingdom at the time of the search. A systematic search of studies that assessed reproductive health outcomes in women taking either orlistat, liraglutide or semaglutide was undertaken in July 2023 and updated in January 2024 across MEDLINE, Embase, CINAHL, Scopus, ClinicalTrials.gov, PROSPERO, Epistemonikos and OpenGrey. Studies focused on polycystic ovarian syndrome, diabetes or animals were excluded. Titles and abstracts were screened, and data from included articles were extracted. After removal of duplicates, 341 titles remained, of which 318 were excluded. Of the final 18 articles included, there were five interventional trials, one retrospective case-control study, six narrative reviews, two systematic reviews, three systematic review protocols and one registry protocol yet to start recruitment. All five interventional trials involved orlistat given preconceptionally, showing no improvement in live birth rate, despite improvement in reproductive hormone levels. There were no studies with primary data about GLP-1 RAs. There were no qualitative studies. There is an absence of primary data about the role of GLP-1 RAs on the reproductive health of women of childbearing age without polycystic ovarian syndrome. Future research should explore short- and long-term effects on reproductive health, pregnancy outcomes and experiences.
