“…REE and minute ventilation were measured with a computerized, open circuit ventilation system (Metavine-N; Vine, Tokyo, Japan) and associated software (Meta Data Viewer, Vine) as previously reported [3][4][5] . All patients came to the measurement session after an overnight fast (8 p.m. to 8 a.m.).…”

Objective: This study examined the basal metabolic rate in patients with twin pregnancies and compared the results with those of singleton pregnancies and non-pregnant women. Methods: In 15 non-pregnant women, 14 patients with twin and 25 patients with singleton pregnancies, the resting energy expenditure was measured using an open-circuit ventilatory system during the third trimester of pregnancy. Results: The averaged resting energy expenditure in patients with twin pregnancy was 1,636 ± 174 kcal/day, significantly higher than that in patients with singleton pregnancy (1,456 ± 158 kcal/day; p < 0.05). Both of these levels are significantly higher than those in non-pregnant women (1,228 ± 132 kcal/day; p < 0.05). Conclusion: Our results indicate that the estimated increased metabolic demands in patients during the third trimester of twin pregnancy are about 10% higher than those in women with singleton pregnancy. A prospective clinical study concerning nutrition counseling is needed.

“…HG has been described as a form of prolonged starvation, 25,38 with several researchers comparing the malnutrition experienced by women with HG to the malnutrition experienced by pregnant women during famines. 39,40 In terms of weight, there was a median change from pre-pregnancy weight to current weight of −1.17 kg (IQR 3.48), which equated to a decrease of 1.89% (IQR 4.8%).…”

BackgroundHyperemesis 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.MethodRecruitment 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.ResultsOne 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).ConclusionNutritional 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.
