RESUMO

Folate, vitamin D and iodine are key micronutrients in pregnancy, with deficiency associated with poor maternal and infant outcomes. For folate and vitamin D especially, deficiency is more common amongst women with obesity and recommended intakes and guidance on supplementation varies worldwide. The present study aims to investigate dietary and supplementary intakes of these micronutrients amongst a population of pregnant women with obesity in the United Kingdom, alongside key maternal demographic characteristics. Expectant women (n = 75) with a body mass index ≥ 30 kg/m2 at first antenatal appointment were recruited at 12 weeks gestation. Participants were asked about their supplement use preconception and during trimester one in a baseline questionnaire which also asked about demographic characteristics. Women also completed a four day diet diary from which dietary and supplemental intakes of micronutrients intakes were estimated. Folic acid was taken by 96% of women at any point in trimester 1, whilst only 26% of women took the higher 5 mg dose recommended for women with obesity in the UK. For vitamin D and iodine, 56% and 44% of women met the UK RNI, respectively. Maternal age was positively associated with taking supplements of any kind and the 5 mg folic acid supplement, whilst parity was inversely associated with both outcomes. This study strengthens the rationale for further work to be done raising awareness of the need for women with obesity to supplement both with a higher dose of folic acid and vitamin D and to be aware of the role of iodine during pregnancy.

RESUMO

A diet high in dietary fibre (DF) is thought to help reduce cholesterol levels, may control blood glucose levels and reduces gut transit time. However, people often fail to consume the recommended quantity of DF. The aim of this study was to supplement two types of bread with some novel functional food ingredients; waxy wheat flour (WF), inulin (IN) and guar gum (GG) to develop products rich in DF. Response surface methodology (RSM) was employed to study the effect of DF on two different breads. Breads were assessed using Cryo-SEM for its microstructure pattern, and physical attributes (pita; springiness, chewiness and hardness, Tandoori; hardness and elasticity). The results showed that, for pita bread, the outcome showed that IN and GG alone significantly increased hardness and chewiness and decreased springiness. WF addition only decreased springiness. GG linearly increased pita height and volume, but it quadratically increased weight loss. Moreover, IN increased volume and height in a quadratic way. Regarding Tandoori bread, IN reduced bread toughness, but showed no effect on extensibility. WF alone increased volume and diameter. The microstructure also showed that the novel ingredients modified starch gelatinisation and gluten-starch matrix in both pita and Tandoori breads differently. Therefore, the influence of the three functional ingredients alone and in combinations influenced quality parameters dissimilarly.

RESUMO

Maternal dietary micronutrients and omega-3 fatty acids support development of the fetal and neonatal immune system. Whether supplementation is similarly beneficial for the mother during gestation has received limited attention. A scoping review of human trials was conducted looking for evidence of biochemical, genomic, and clinical effects of supplementation on the maternal immune system. The authors explored the literature on PubMed, Cochrane Library, and Web of Science databases from 2010 to the present day using PRISMA-ScR methodology. Full-length human trials in English were searched for using general terms and vitamin A, B12, C, D, and E; choline; iodine; iron; selenium; zinc; and docosahexaenoic/eicosapentaenoic acid. Of 1391 unique articles, 36 were eligible for inclusion. Diverse biochemical and epigenomic effects of supplementation were identified that may influence innate and adaptive immunity. Possible clinical benefits were encountered in malaria, HIV infections, anemia, Type 1 diabetes mellitus, and preventing preterm delivery. Only limited publications were identified that directly explored maternal immunity in pregnancy and the effects of micronutrients. None provided a holistic perspective. It is concluded that supplementation may influence biochemical aspects of the maternal immune response and some clinical outcomes, but the evidence from this review is not sufficient to justify changes to current guidelines.

RESUMO

BACKGROUND: The number of children with obesity has increased in Saudi Arabia, which is a significant public health concern. Early diagnosis of childhood obesity and screening of the prevalence is needed using a simple in situ method. This study aims to generate statistical equations to predict body fat percentage (BF%) for Saudi children by employing machine learning technology and to establish gender and age-specific body fat reference range. METHODS: Data was combined from two cross-sectional studies conducted in Saudi Arabia for 1,292 boys and girls aged 8-12 years. Body fat was measured in both studies using bio-electrical impedance analysis devices. Height and weight were measured and body mass index was calculated and classified according to CDC 2,000 charts. A total of 603 girls and 374 boys were randomly selected for the learning phase, and 153 girls and 93 boys were employed in the validation set. Analyses of different machine learning methods showed that an accurate, sensitive model could be created. Two regression models were trained and fitted with the construction samples and validated. Gradient boosting algorithm was employed to achieve a better estimation and produce the equations, then the root means squared error (RMSE) equation was performed to decrease the error. Body fat reference ranges were derived for children aged 8-12 years. RESULTS: For the gradient boosting models, the predicted fat percentage values were more aligned with the true value than those in regression models. Gradient boosting achieved better performance than the regression equation as it combined multiple simple models into a single composite model to take advantage of that weak classifier. The developed predictive model archived RMSE of 3.12 for girls and 2.48 boys. BF% and Fat mass index charts were presented in which cut-offs for 5th, 75th and 95th centiles are used to define 'under-fat', 'normal', 'overfat' and 'subject with obesity'. CONCLUSION: Machine learning models could represent a significant advancement for investigators studying adiposity-related issues in children. These models and newly developed centile charts could be useful tools for the estimation and classification of BF%.

RESUMO

BACKGROUND: It is widely acknowledged that maternal obesity and excessive gestational weight gain (GWG) are associated with increased risk of fetal macrosomia and recent studies have suggested a role for the timing and composition of GWG. AIMS: To examine the effect of the rate of change in GWG and maternal upper-body subcutaneous fat on neonatal anthropometric outcomes in a pilot observational study amongst women with obesity. STUDY DESIGN: Expectant women with a body mass index (BMI) > 30 kg/m2 at first antenatal appointment were recruited at 12 weeks gestation. Maternal height, weight and skinfold thickness (SFT) measurements were collected at baseline and repeated at 28 and 36 weeks gestation. Following delivery, World Health Organisation (WHO)-UK infant birthweight z-scores were calculated, and infant anthropometric measurements were obtained. RESULTS: The sum of upper body SFT measurements increased in mid-pregnancy (0.08 ± 0.71 mm/week) and decreased in late pregnancy (-0.04 ± 1.17 mm/week). After adjustment for maternal age, BMI and parity, mid- but not late- pregnancy GWG was positively associated with infant birthweight z-score (p<0.05), while mid- but not late-pregnancy changes in the sum of SFT were inversely associated with infant birthweight z-score (p<0.01). CONCLUSIONS: The present study suggests that mid- rather than late-pregnancy changes in weight and upper-body subcutaneous fat are associated with infant birthweight. Further research is required in larger, more diverse populations to explore whether pregnancy interventions aiming to improve maternal and offspring health can be personalised beyond BMI and GWG.

RESUMO

Fruit consumption is recommended as part of a healthy diet. However, consumption of fruit in the form of juice is positively associated with type 2 diabetes risk, possibly due to resulting hyperglycemia. In a recent study, fruit juice prepared by nutrient extraction, a process that retains the fiber component, was shown to elicit a favorable glycemic index (GI), compared to eating the fruit whole, in healthy weight adults. The current study expanded on this to include individuals with obesity, and assessed whether the nutrient extraction of seeded fruits reduced GI in a higher disease risk group. Nutrient extraction was shown to significantly lower GI, compared to eating fruit whole, in subjects with obesity (raspberry/mango: 25.43 ± 18.20 vs. 44.85 ± 20.18, p = 0.034 and passion fruit/mango (26.30 ± 25.72 vs. 42.56 ± 20.64, p = 0.044). Similar results were found in those of a healthy weight. In summary, the current study indicates that the nutrient-extraction of raspberries and passionfruit mixed with mango lowers the GI, not only in healthy weight individuals, but also in those with obesity, and supports further investigation into the potential for nutrient extraction to enable increased fruit intake without causing a high glycemic response.

RESUMO

BACKGROUND/OBJECTIVES: Short sleep duration has been linked to maternal hyperglycaemia following a 1-h 50 g oral glucose tolerance test (OGTT) in observational studies conducted primarily in the USA. Our objective was to examine the relationship between objectively measured sleep duration and plasma glucose values following the 2-h 75 g OGTT routinely used in the UK amongst women with obesity. METHODS: Sleep and OGTT data were available for 49 pregnant women who wore wrist actigraphs for at least two nights, and took a 2-h 75 g OGTT at the end of their second trimester. Multivariable regression was used to evaluate associations between sleep duration and OGTT results. RESULTS: Higher 2-h plasma glucose values were significantly associated with shorter sleep duration and higher maternal age and BMI, with no association observed between wake after sleep onset (WASO) and 2-h plasma glucose values. No associations were observed between fasting plasma glucose values and any sleep parameters. CONCLUSIONS: We found that shorter sleep duration, as measured using actigraphy, is associated with higher 2-h plasma glucose values following a 2-h 75 g OGTT in the UK. These findings are in keeping with those observed elsewhere in the world, employing alternative OGTT protocols. Future studies should investigate sleep extension as a potential candidate for inclusion in future RCTs aiming to improve glucose tolerance and prevent GDM amongst those at risk.

RESUMO

Substituting sugar-sweetened for artificially sweetened beverages may reduce energy intakes. This study aims to ascertain the acute glycaemic effects of the NNS aspartame and acesulfame-K in UK diet-cola (DC). Ten healthy participants attended the laboratory fasted on three occasions. Individuals drank (1) 25 g glucose in 125 mL water + 236 mL water, (2) 25 g glucose in 125 mL water with 236 mL DC and (3) 236 mL sucrose-sweetened cola with 125 mL water. Blood (glucose) was measured pre-test and every 15 minutes over a 120-minute period using portable glucometers. The glucose-control and glucose + DC elicited similar blood glucose rises above pre-prandial levels. Sucrose-sweetened cola showed a non-significant lower rise in postprandial glycaemia, exhibiting the lowest glycaemic index (GI) (77.0 ± 9.1). GI of glucose (100.0 ± 15.2) and glucose + DC (104.3 ± 8.5) was similar and a one-way repeated-measures ANOVA showed no significant differences in glycaemic response between test drinks (F(2,29) = 1.68, p > .05). Results demonstrate the glycaemic inactivity of non-nutritive sweeteners.

RESUMO

To deliver a patient-centred service, emergency departments (EDs) must be efficient, effective and meet the needs of the local population. This article describes a service redesign of unscheduled care in a hospital in Wales, which followed the principles of prudent healthcare to improve patient experiences. Extending the roles of nurse specialist practitioners was a major component of the redesign. Six working groups were established to guide the process, one of which was responsible for working cooperatively with the local community, which was concerned about perceived 'downgrading' of the ED. The service redesign was completed in 2016 and evaluation shows the target for patients being seen in under four hours improved from 88% to 96%, significantly more acute medical admission patients were discharged in less than 24 hours, and patient satisfaction increased overall.

RESUMO

BACKGROUND: Obesity rates in Saudi Arabia are amongst the highest in the world. It is known that teenage girls are less active than teenage boys, but less is known about the diet and activity patterns in younger girls. Therefore this study sought to investigate dietary intake and daily physical activity in girls aged 8-11 years old in Saudi Arabia. METHODS: This was a cross- sectional observational study conducted in seven schools across the city of Makkah. A total of 266 girls had anthropometric measurements taken including height, weight, waist circumference and body fat estimations. Dietary assessment using a 4 day unweighed diet diary was undertaken in 136 of these participants, and 134 agreed to monitor their physical activity for the 4 days using an accelerometer. After exclusion for under-reporting, 109 remained in the dietary analysis and 78 in the physical activity analyses. Differences in means between BMI groups were determined using one-way ANOVA with post hoc Tukey test. Multivariable linear regression analysis was performed to look at the effect of multiple variables on body weight. RESULTS: A total of 30% of participants were classified obese or overweight. There was a significant difference in the mean daily energy intake between the BMI groups with the obese group having the highest energy, fat, carbohydrate and protein intake (obese group: 2677 ± 804 kcal/d; healthy weight group: 1806 ± 403 kcal/d, p < 0.001), but the percentage contribution of the macronutrients to energy intake remained the same across the BMI groups. There were no differences in number of steps taken per day or time spent in moderate to vigorous intensity exercise according to BMI category. Most of the girls did not meet daily physical activity guidelines (5969 to 6773 steps per day and 18.5 - 22.5 mins per day of moderate to vigorous activity). Multiple linear regression showed that energy intake positively predicted body weight (Beta = 0.279, p =0 .001), whereas, total energy expenditure per kg of body weight and family income had a significant negative influence on body weight (Beta = -0.661, p < 0.001; -0.131, p = 0.028 respectively). CONCLUSIONS: The results of this cross sectional analysis suggest that obesity in girls aged 8-11 years is linked to excessive energy intake from all macronutrients and the majority of girls in all weight categories are inactive. Research should be conducted to further investigate causal relationships in longitudinal studies and develop interventions to promote dietary change and activity that is culturally acceptable for girls in Saudi Arabia.

RESUMO

Good nutrition in the early years of life is essential, yet the diets of many pre-school children in the UK are known to be poor. Understanding the decisions parents make when feeding young children is very important in determining what type and nature of interventional support may be developed to promote good nutrition. The aim of this study was to explore using qualitative methods, parental perceptions of feeding their children in order to inform the development of a nutrition intervention. Focus groups (n = 33) and individual interviews (n = 6) were undertaken with parents, most of whom were attending children's centres in two deprived populations from one urban (Islington, north London) and one rural (Cornwall) location in England. Accounts of feeding pre-school children were primarily concerned with dealing with the practicalities of modern life, in particular the cost of food and the need to manage on a restricted household budget. Time pressures, a lack of perceived knowledge and confidence in preparing food and managing conflict over food choices between family members were also strong themes. Parents commonly reported differences between how they would like to feed their children and the reality of what they were able to do in their circumstances. These findings suggest that the poor eating habits of many pre-school children may be less a case of parental ignorance but rather the product of a range of coping strategies. Designing an intervention, which helps parents to build their confidence and self-efficacy, may enable them to make positive changes to their children's diets.

RESUMO

Good nutrition in the early years of life is vitally important for a child's development, growth and health. Children's diets in the United Kingdom are known to be poor, particularly among socially disadvantaged groups, and there is a need for timely and appropriate interventions that support parents to improve the diets of young children. The Medical Research Council has highlighted the importance of conducting developmental and exploratory research prior to undertaking full-scale trials to evaluate complex interventions, but have provided very limited detailed guidance on the conduct of these initial phases of research. This paper describes the initial developmental stage and the conduct of an exploratory randomised controlled trial undertaken to determine the feasibility and acceptability of a family-centred early years' nutrition intervention. Choosing Healthy Eating when Really Young (CHERRY) is a programme for families with children aged 18 months to 5 years, delivered in children's centres in one urban (Islington) and one rural (Cornwall) location in the United Kingdom. In the development stage, a mixed-methods approach was used to investigate the nature of the problem and options for support. A detailed review of the evidence informed the theoretical basis of the study and the creation of a logic model. In the feasibility and pilot testing stage of the exploratory trial, 16 children's centres, with a sample of 394 families were recruited onto the study. We hope that the methodology, which we present in this paper, will inform and assist other researchers in conducting community-based, exploratory nutrition research in early years settings.

RESUMO

In order to develop successful interventions to improve children's diets, the factors influencing food choice need to be understood. Parental food involvement - the level of importance of food in a person's life - may be one of many important factors. The aim of this study was to determine whether parental food involvement is associated with parents' and children's diet quality. As part of an intervention study, 394 parents with children aged between 18 months and 5 years were recruited from children's centres in Cornwall and Islington, UK. Questionnaires were used to collect data on socio-demographic characteristics, parents' diets, and attitudes towards food including food involvement. Children's diets were assessed using the multiple pass 24 h recall method. Parents reported low intakes of fruits and vegetables and high intakes of sugary items for themselves and their young children. Parental food involvement was strongly correlated with consumption of fruits and vegetables (amount and diversity) for both parents and children. Correlations with consumption of sugary drinks and snacks/foods were not significant. These findings indicate that parental food involvement may influence consumption of fruits and vegetables, more so than sugary items. Further research is needed to investigate how parental food involvement could mediate dietary changes.

RESUMO

A questionnaire was designed to obtain information about factors affecting vitamin D status in Middle Eastern people living in the UK. A total of 242 questionnaires were returned out of 350 distributed. A total of 85% of the sample was estimated to have a low vitamin D intake (< 5 µg/d). Other risk factors for vitamin D insufficiency included covering skin from sunlight (62% men and 84% women); low use of vitamin D containing supplements (18.5%) and being overweight or obese (49% men and 44% women). Vitamin D intake was lowest in the Kurdish ethnic group (2.18 µg/d) and in those with primary (1.83 µg/d) and secondary school (2.14 µg/d) level education compared to higher education (3.0-3.59 µg/d). Vitamin D intake was highest in those aged 40-49 years (4.0 µg/d), those born in the Levant (4.29 µg/d), and in those who were obese (3.60 µg/d).

RESUMO

OBJECTIVE: The present study explored parents' requirements for healthy eating support prior to the development of a tailored intervention. DESIGN: A cross-sectional study of parents attending children's centres. SETTING: Children's centres in Cornwall (rural south-west England) and Islington (urban London borough). SUBJECTS: A total of 261 parents (94.2% female) of pre-school children (aged 2­5 years) completed a questionnaire on factors influencing food choice, and preferences for and views on healthy eating support. RESULTS: Parents reported that health, taste, freshness and quality were the most important factors influencing their food choices for their pre-school children. The importance of individual factors varied according to level of educational attainment. Over a third (38 %) of parents said they wanted more advice on healthy eating for children. Less educated parents showed the greatest interest in learning more about several aspects: what a 'healthy diet' means, how to prepare and cook healthy food, how to understand food labels, budgeting for food, examples of healthy food and snacks for children, appropriate portion sizes for children and ways to encourage children to eat well. CONCLUSIONS: There was demand for healthy eating support among parents of pre-school children, especially those who are less educated, in one rural and one urban area of England

RESUMO

Poor nutrient intake during pregnancy can adversely affect both infant and maternal health. The aim was to investigate the efficacy of multiple-micronutrient supplementation during pregnancy in a socially deprived population in the developed world. We conducted a randomised, double-blind, placebo-controlled trial of multiple-micronutrient supplementation including 20 mg Fe and 400 microg folic acid, from the first trimester of pregnancy in 402 mothers, in East London, UK. Nutrient status was measured at recruitment, and at 26 and 34 weeks of gestation. Infants were weighed at birth. At recruitment the prevalence of anaemia was 13 %, vitamin D insufficiency 72 %, thiamin deficiency 12 % and folate deficiency 5 %, with no differences between groups. Only 39 % of women completed the study; rates of non-compliance were similar in both groups. Intention-to-treat analysis showed that participants receiving treatment had higher mean Hb at 26 weeks of gestation (110 (sd 10) v.108 (sd 10) g/l; P = 0.041) and 34 weeks of gestation (113 (sd 12) v.109 (sd 10) g/l; P = 0.003) and packed cell volume concentrations at 26 weeks of gestation (0.330 (sd 0.025) v. 0.323 (sd 0.026) l/l; P = 0.011) and 34 weeks of gestation (0.338 (sd 0.029) v. 0.330 (sd 0.028) l/l; P = 0.014) compared with controls. Analysis of compliant women showed supplemented women had higher median concentrations of serum ferritin, erythrocyte folate and 25-hydroxyvitamin D later in gestation than controls. In the compliant subset (n 149), placebo mothers had more small-for-gestational age (SGA) infants (eight SGA v. thirteen; P = 0.042) than treatment mothers. Baseline micronutrient deficiencies were common; the multiple-micronutrient supplement was well-tolerated and improved nutrient status. Multiple-micronutrient supplements from early pregnancy may be beneficial and larger studies are required to assess impact on birth outcomes and infant development.

RESUMO

OBJECTIVE: To evaluate the effectiveness of a computer-generated tailored intervention leaflet compared with a generic leaflet aimed at increasing brown bread, wholegrain cereal, fruit and vegetable intakes in adolescent girls. DESIGN: Clustered randomised controlled trial. Dietary intake was assessed via three 24 h dietary recalls. SETTING: Eight secondary schools in areas of low income and/or high ethnic diversity, five in London and three in the West Midlands, UK. SUBJECTS: Girls aged 12-16 years participated (n 823) and were randomised by school class to receive either the tailored intervention (n 406) or a generic leaflet (n 417). RESULTS: At follow-up 637 (77 %) participants completed both baseline and follow-up dietary recalls. The tailored intervention leaflet had a statistically significant effect on brown bread intake (increasing from 0.39 to 0.51 servings/d) with a smaller but significant increase in the control group also (increasing from 0.28 to 0.35 servings/d). The intervention group achieved 0.05 more servings of brown bread daily than the control group (P < 0.05), which is equivalent to 0.35 servings/week. For the other foods there were no significant effects of the tailored intervention. CONCLUSIONS: The intervention group consumed approximately 0.35 more servings of brown bread weekly than the control group from baseline. Although this change between groups was statistically significant the magnitude was small. Evaluation of the intervention was disappointing but the tailored leaflet was received more positively in some respects than the control leaflet. More needs to be done to increase motivation to change dietary intake in adolescent girls.

RESUMO

We have previously found high rates of poor iron and folate status in women who had delivered a low birthweight baby (LBW) in an ethnically diverse inner-city area of the UK. However, little was known of the nutritional status in the local general obstetric population. We therefore investigated biochemical measures of nutritional status in the first trimester of the first pregnancy. Routine blood samples collected at the antenatal booking clinic were analysed for haemoglobin (Hb), serum ferritin, red cell folate (RCF) (n = 100) and erythrocyte transketolase activation coefficient (ETKAC) for thiamin status (n = 90). We found 9% of women in our sample had a low Hb level, 10% had a low serum ferritin and only one had a low RCF. This is a substantially lower number of women with biochemical deficiencies than we found previously in women three months after delivering a LBW baby. However, 34% had low thiamin status. Thiamin status was negatively correlated with gestational age at birth (r = -0.407, p < 0.001). Differences in nutritional status were observed between ethnic and socio-economic groups. Hb levels differed between ethnic (p = 0.001) and socio-economic groups (p = 0.02), with Africans and women in manual occupations/unwaged having the lowest Hb levels. RCF levels also differed between groups (p < 0.001) with Caucasians and those in non-manual occupations having highest levels. ETKAC also differed between ethnic groups (p = 0.008) with Africans having the highest level indicating a poorer status. The study highlights the need to improve nutrition particularly in ethnic minorities and low income groups who are most at risk of adverse birth outcomes such as LBW.

RESUMO

The aim of this study was to assess the effect of coarse wheat bran on specific bowel function parameters and symptoms in patients with irritable bowel syndrome (IBS). A longitudinal, prospective, randomised, placebo-controlled trial was undertaken. The duration of treatment was eight to 12 weeks and this consisted of 10-20 g/day of coarse wheat bran or a low fibre placebo taken in addition to the normal diet. Twenty-eight outpatients fulfilling the Rome criteria for constipation-predominant IBS were recruited to the trial (14 in the treatment group; 14 in the placebo group). Twelve people completed the trial in the treatment group and ten in the placebo group. The main outcome measures included changes in symptoms recorded in a diary, changes in objective measurements of bowel function and subjective overall feelings of improvement. The bran group significantly increased their non-starch polysaccharide (NSP) intake over that of the placebo group (p < 0.05). Mean stool wet weight increased significantly more in the bran group than in the placebo group (p < 0.05), but other bowel function measurements and all recorded symptoms were not different. Many patients reported changes in bowel habit that were not reflected in the objective measurements. The addition of coarse wheat bran to the diet increased NSP ingestion and stool wet weight in this group of IBS patients, but no evidence was obtained that such treatment was of benefit to these patients, other than a placebo effect on symptoms.

RESUMO

Subarachnoid haemorrhage affects up to 9,000 people a year in the UK (Lindsay and Bone 1997) and is a devastating condition. Although many patients make a good physical recovery, some are left with cognitive and perceptual deficits. Early rehabilitation and support is essential, and caring for these patients and their families is a major challenge for nurses.
