RESUMO
ObjectiveTo explore the influence of excessive weight gain during pregnancy in pre-pregnancy overweight and obese women on pregnancy outcomes and neonatal conditions, and to provide scientific evidence for formulating weight management strategies before and during pregnancy and prevent adverse pregnancy outcomes. MethodsClinical data of 2 172 parturients collected from a community in Huangpu District from 2017 to 2021 were retrospectively analyzed, and they were divided into pre-pregnancy overweight and obesity group (n=530), normal pre-pregnancy weight group(n=937), and underweight pre-pregnancy group(n=705) according to maternal precursor body mass index (BMI). Based on their weight gain during pregnancy,the parturient were divided into moderate gestational weight gain (MGWG) group and excessive gestational weight gain (EGWG) group. Meanwhile, the pregnancy and neonatal outcomes such as postpartum hemorrhage, puerperal infection, placental abruption, premature rupture of membranes, mode of delivery, premature birth, stillbirth, fetal distress, admission to the intensive care unit (ICU), macrosomia, and Apgar score, were recorded. Then the differences in pregnancy and neonatal outcomes between groups were compared. The effects of pre-pregnancy BMI and gestational weight gain on pregnancy outcomes and neonatal conditions was retrospectively analyzed. ResultsThe pre-pregnancy overweight and obese group had higher proportions of placental abruption, premature rupture of membranes, cesarean section, premature birth, fetal distress, and macrosomia compared to the normal pre-pregnancy weight group and the underweight pre-pregnancy group, with Apgar scores lower than the normal pre-pregnancy weight group and the underweight pre-pregnancy group (all P<0.05). The EGWG group had higher proportions of postpartum hemorrhage, placental abruption, premature rupture of membranes, cesarean section, premature birth, fetal distress, admission to the ICU, and macrosomia than the MGWG group (all P<0.05). In the pre-pregnancy overweight and obese group, the EGWG group had higher proportions of placental abruption, premature rupture of membranes, premature birth, fetal distress, admission to the ICU, and macrosomia than the MGWG group, with lower Apgar scores than the MGWG group (all P<0.05). In the normal pre-pregnancy weight group, the EGWG group had higher proportions of placental abruption, premature rupture of membranes, premature birth, fetal distress, admission to the ICU, and macrosomia than the MGWG group (all P<0.05). In the pre-pregnancy overweight and obese group, the EGWG group had higher proportions of premature rupture of membranes, cesarean section, premature birth, fetal distress, and macrosomia than the EGWG group in the normal pre-pregnancy weight group(all P<0.05). Logistic regression analysis showed that EGWG in pre-pregnancy overweight and obese women was a risk factor for placental abruption (OR=2.971, 95%CI: 1.098‒8.042), premature rupture of membranes (OR=4.662, 95%CI: 2.798‒7.770), cesarean delivery (OR=1.375,95%CI: 1.260‒2.541), premature birth (OR=4.249, 95%CI: 2.384‒7.573), fetal distress (OR=3.238, 95%CI: 1.589‒6.598), admission to the ICU (OR=3.010, 95%CI: 1.265‒7.164), and macrosomia (OR=5.437, 95%CI: 3.392‒8.716) (all P<0.05). ConclusionExcessive gestational weight gain in pre-pregnancy overweight and obese women is a risk factors for placental abruption, premature rupture of membranes, cesarean section, premature birth, fetal distress, admission to the ICU, and macrosomia.
RESUMO
Objective:To compare the accuracy of 11 ultrasound parameters prediction formulas for fetal body mass,and to explore the effect of gestational weight gain(GWG)on the accuracy of ultrasound prediction of fetal body mass.Methods:A total of 502 single and full-term postpartum women who gave birth from August 2020 to December 2020 at Jinshan Hospital,Fudan University were collected.The gestational weight gain,fetal ultrasound measurement indicators within 7 days before delivery,and newborn birth weight were calculated and analyzed.The accuracy of multiple ultrasound prediction formulas were calculated and analyzed.According to the criteria for weight gain during pregnancy,the reasonable weight gain during pregnancy was 12.5-18.0 kg for singleton pregnancies with pre-pregnancy(body mass index)BMI<18.5 kg/m2,11.5-16.0 kg for those with BMI 18.5-24.9 kg/m2,7.0-11.5 kg for those with BMI 25.0-29.9 kg/m2,and 5.0-9.0 kg for those with BMI≥30.0 kg/m2.The cases were divided into the group with insufficient GWG(125 cases),the normal group(202 cases),and the group with too much GWG(175 cases)to analyze the effect of different GWG on the accuracy of ultrasound pre-diction of fetal body mass.Results:Among the 11 ultrasound parameter formulas for predicting fetal body mass,the HadlockⅢformula predicted fetal body mass with an absolute error of 186.64±149.28 g and a relative error of(5.52±4.18)%,which was the smallest error among 11 prediction formulas,with a statistically significant difference(P<0.05).The absolute and relative error compliance rates were 72.31%,86.25%,respectively,both of which were the highest,and the difference was statistically significant(P<0.05).When the HadlockⅢformula was used to predict birth weight in the insufficient GWG group,the normal group,and the group with too much GWG,the absolute errors were 190.23±136.69 g,148.12±99.39 g,228.54±189.57 g,and the relative errors were(5.95±4.25)%,(4.40±2.78)%,(6.49±5.09)%,respectively,and the differences were statistically significant(P<0.05).Conclusions:The accuracy of Hadlock Ⅲ formula in predicting fetal body mass is better than that of other formulas,but its accuracy can be affected by GWG,and it is necessary to consider multiple as-pects when estimating fetal body mass in clinical practice.
RESUMO
【Objective】 To understand the prevalence of overweight/obesity among school-age children in Pudong New Area of Shanghai, and to explore the influence of gestational weight gain and pre-pregnancy body mass index (BMI) on weight status of school-age children. 【Methods】 From November to December 2020,a stratified cluster sampling method was adopted to select first-grade students from 13 primary schools in Pudong New Area of Shanghai.After matching with the birth monitoring database, 755 students with complete birth information were selected as the study subjects.The relevant information of mothers before and during pregnancy was retrospectively collected, and the effects of pregnancy weight gain combined with pre-pregnancy BMI on overweight/obesity in school-age children were analyzed. 【Results】 1) The prevalence rates of overweight and obesity of first-grade children were 15.89% and 18.41%, respectively.2) Maternal excessive weight gain during pregnancy (OR=1.678) and overweight/obesity before pregnancy (OR=2.315,2.412) were risk factors for overweight/obesity of the offspring at school age(P<0.05).3) For mothers who were underweight before pregnancy, excessive weight gain during pregnancy was associated with overweight/obesity in school-age children in their offspring (OR=7.436, 95%CI: 1.489 - 37.143,P<0.05).4) Excessive weight gain during pregnancy combined with overweight/obesity before pregnancy significantly increased the risk of overweight/obesity in offspring (OR=3.606, 95%CI: 2.030 - 6.405, P<0.05). Mothers who gained a moderate amount of weight during pregnancy and were emaciated before pregnancy had a significantly lower risk of overweight/obesity in their school-age children (OR=0.217, 95%CI: 0.049 - 0.967, P<0.05). 【Conclusion】 Excessive weight gain during pregnancy increases the risk of overweight/obesity in school-age children in their offspring, strengthening pregnancy health education and perinatal care to help pregnant women maintain appropriate weight gain during pregnancy may be an important and novel strategy to prevent childhood obesity.
RESUMO
ObjectiveTo construct a quantitative prediction model of three indicators(moisture absorption rate, film thickness and coating weight gain) during the coating process of Vitamin C Yinqiao tablets(VCYT) by near-infrared spectroscopy(NIRS), and to realize the endpoint judgment. MethodReal-time NIRS data of 4 batches of VCYT during the coating process were collected by diffuse reflection method. The coating method employed was the rolling coating method, and the samples were obtained at the spray stage from the coater's sampling port every 10 minutes, and 57 batches of samples(about 1 800 tablets) were collected at various coating times, the tablets were embedded in molten paraffin, cut longitudinally, and observed by stereomicroscope. The film thickness, with a target value of 38 μm, was then measured using Motic Images Advanced 3.2 software. Furthermore, the mositure absorption rate of samples, aiming for a target value of 3%, was determined in accordance with guiding principles for drug hygroscopicity testing in the 2020 edition of Chinese Pharmacopoeia, and 3 samples were randomly selected from each batch(10 tablets per batch), and the coating weight gain was calculated(target value of 4%). Partial least squares regression(PLSR) was used to construct a quantitative model of the 3 coating indicators, and the predicted values of the coating indicators were smoothed using the moving average method and used to determine the coating endpoints. ResultThe prediction determination coefficients(Rp2) for moisture absorption rate, film thickness and coating weight gain were 0.933 4, 0.932 6 and 0.965 9, the root mean square errors of prediction(RMSEP) were 0.163 5%, 1.870 9 μm and 0.240 3%, the relative percent deviations(RPD) were 3.711 0, 2.760 7 and 5.415 8, respectively. The results of the external validation set demonstrated that the real-time predicted values obtained by the models exhibited the same trend as the measured values, and the coating endpoint could be accurately predicted(with a prediction error of less than 7.32 min and a relative error of less than 5.63%). ConclusionThe established NIRS model exhibits excellent predictive performance and can be used for quality control of VCYT during the coating process.
RESUMO
Abstract The study was conducted to evaluate the effect of Moringa olifera on the growth and gut health of Tilapia (Oreochromis niloticus). The feed having 30% crude protein was prepared as an experimental diet with 4%, 8% and 10% M. olifera leaf supplementation, respectively. The control diet was devoid of M. olifera leaves. The 10 weeks feeding trial was carried out on 60 fish in aquaria. Fish was fed @ 3% of body weight twice a day. Diet with the high level of inclusion of M. olifera leaves significantly increased the growth rate, Survival Rate (SR), Specific Growth Rate (SGR) and Feed Conversion Efficiency (FCE) in all treatment groups compared to the control group. Similarly, Feed Conversion Ratio (FCR) gradually decreased and found highly-significant. To check the gut health of the Tilapia, random samples were selected and dissected. Nutrient agar was used as culture media to check the growth of bacteria. Pour Plate Method was used for viable colonies count by colony counter. Through staining method, the different bacteria such as Escherichia coli, Salmonella, Shigella and Pseudomonas aeruginosa were identify abundantly in the intestine of control diet fish but less number present in treatment diets groups. These results showed that M. olifera leaves up to 10% of dietary protein can be used for Nile tilapia for significant growth and healthy gut microbiota of fish.

Da mesma forma, a taxa de conversão de alimentação (FCR) diminuiu gradualmente e foi considerada altamente significativa. Para verificar a saúde intestinal da tilápia, amostras aleatórias foram selecionadas e dissecadas. O ágar nutriente foi usado como meio de cultura para verificar o crescimento das bactérias. O método da placa de Verter foi usado para a contagem de colônias viáveis por contador de colônias. Através do método de coloração, diferentes como Escherichia coli, Salmonella, Shigella e Pseudomonas aeruginosa foram identificados abundantemente no intestino de peixes da dieta controle, mas em menor número nos grupos de dieta de tratamento. Esses resultados mostraram que M. olifera deixa até 10% da proteína dietética e pode ser usado para tilápia do Nilo para um crescimento significativo e microbiota intestinal saudável de peixes.

Abstract Objectives The study aimed to evaluate the factors associated with interdialytic weight gain in users of haemodialysis services in a metropolitan region of Brazil. Methods This is an cross-sectional epidemiological study with 1,024 individuals with chronic kidney disease on haemodialysis in Brazil. Interdialytic weight gain was evaluated by the percentage weight gain between one haemodialysis session and another. The variables included in the binary logistic regression analysis were selected by considering p< 0.10 in the bivariate test. Results We demonstrated that having more years of study (OR=0.537;CI 95% = 0.310-0.931; p=0.027) and be overweight (OR=0.661;CI 95% = 0.461-0.948; p=0.024) or obese (OR=0.387;CI 95% = 0.246-0.608; p=<0.001) reduced the chances of users having high interdialytic weight gain. Those who did not have paid work (OR=2.025;CI 95% = 1.218-3.365; p=0.007) and not adopting measures to reduce salt increased (OR=1.694;CI 95% = 1.085-2.645; p=0.020) increased the chances of interdialytic weight. Conclusion The results point to an association between the increase in interdialytic weight gain and the absence of paid work and the non-adoption of measures to reduce salt intake in the diet. Therefore, the need for knowledge about these associated factors can be an important alternative for the individual targeting of this population.

ABSTRACT BACKGROUND: Weight retention during the post-partum period is associated with excessive weight gain. OBJECTIVES: To investigate factors associated with maternal weight retention at six months post-partum (PPWR). DESIGN AND SETTING: A prospective cohort study was conducted with 127 women monitored using prenatal services. METHODS: The outcome variable was represented by post-partum maternal weight retention and calculated as the difference between the mother's weight at sixth month post-partum and her pregestational weight. RESULTS: The mean age of the pregnant women was 26.7 ± 5.25 years old, and the post-partum maternal weight retention was 46.5%. The proximal determinants showed a direct association with PPWR after adjusting for the distal and intermediate variables: excessive gestational weight gain (odds ratio [OR]:3.34; confidence interval [CI]:1.16-9.59), greater adhesion to dietary intake pattern 2 (composed of red meats and derivatives, eggs, industrialized foods, and coffee) (OR:2.70; CI:1.16-6.32), and the absence of exclusive maternal breastfeeding in the first month (OR:3.40; CI:1.27-9.12), as well as primiparity (OR:2.36; CI:1.00-5.55), an intermediate determinant. Insufficient weight gain in pregnancy was inversely associated with the outcome (OR:0.35; CI:0.31-0.93). CONCLUSIONS: Among the hierarchical determinants, proximal factors were interrelated with maternal weight retention, indicating that excessive total weight gain, an inadequate dietary intake pattern, and the absence of exclusive maternal breastfeeding in the first month of life work as dampeners of the return to pre-gestational weight. Prepartum and post-partum care interventions can contribute to reducing excess weight in women.
RESUMO
SUMMARY OBJECTIVE: The aim of this study was to examine the relationship of anthro-metabolic indices on maternal and neonatal outcomes. METHODS: This prospective observational study was conducted on healthy mother-baby pairs between January 1, 2023 and July 1, 2023. Detailed sociodemographic information was collected through an interview with the mother. Clinical, biochemical, obstetric, fetal, and neonatal outcomes were abstracted from hospital medical records. Anthropometric measurements were obtained from the examination of mother-baby pairs. RESULTS: A total of 336 healthy mothers-children pairs were included. Mothers of newborn ≥4000 g had higher gestational age (p=0.003), body mass index (p=0.003), gestational weight gain (p=0.016), waist circumferences (p=0.002), and hip circumferences (p=0.001). gestational weight gain was associated with the mode of delivery (p=0.023). waist-to-hip ratio (p=0.005), gestational weight gain (p=0.013), and a body shape ındex (p<0.001) were associated with longer length of hospital stay. Age (p<0.001) and inter-pregnancy interval (p=0.004) were higher in pre-pregnancy underweight/obese mothers. Receiver operating characteristic analysis revealed that maternal waist circumferences (AUC: 0.708, p=0.005), maternal weight (AUC: 0.690, p=0.010), and hip circumferences (AUC: 0.680, p=0.015) were sufficient to predict macrosomia (p<0.05). CONCLUSION: The study demonstrated a significant association between gestational weight gain and cesarean delivery, prolonged hospital stay, and macrosomia. It was also found that maternal body mass index, waist circumferences, and hip circumferences during pregnancy were associated with macrosomia. On the contrary, no significant relationship was found between maternal anthro-metabolic characteristics and maternal-fetal and birth outcomes.
RESUMO
Resumo O objetivo deste artigo é estimar os efeitos dos sintomas de transtornos mentais na gravidez (sintomas depressivos, ansiedade e estresse) no ganho de peso gestacional. Estudo longitudinal, realizado com dados da Coorte de nascimento BRISA, iniciada em 2010 em São Luís, Maranhão. O ganho de peso gestacional foi classificado de acordo com Institute of Medicine. A variável independente foi um construto (variável latente) nomeado de sintomas de transtornos mentais, englobando as variáveis sintomas depressivos, a ansiedade e os sintomas estressantes (todas de forma contínua). Utilizou-se modelagem de equações estruturais, a fim de investigar a associação entre a saúde mental e ganho de peso. Em relação a associação entre sintomas de transtornos mentais e ganho de peso na gestação, não se encontrou efeito total (CP=0,043; p=0,377). Em relação aos efeitos indiretos, também não se encontrou efeito através dos comportamentos de risco (CP=0,03; p=0,368) e através da atividade física (CP=0,00; p=0,974). Finalmente os dados não evidenciaram efeito direto dos sintomas de transtornos mentais durante a gravidez como o ganho de peso gestacional (CP=0,050; p=0,404). O ganho de peso gestacional não apresentou efeito direto, indireto e total nos sintomas de transtornos mentais de gestantes.
Abstract The scope of this article is to estimate the effects of symptoms of mental disorders during pregnancy (depressive symptoms, anxiety and stress) on gestational weight gain (kg). It is a longitudinal study, carried out with data from the BRISA Birth Cohort, which was launched in 2010 in São Luís, Maranhão. Gestational weight gain was classified according to the Institute of Medicine. The independent variable was a construct (latent variable) referred to as symptoms of mental disorders, made up of the depressive symptoms, anxiety and stressful symptoms variables (all on an ongoing basis). Structural equation modeling was used to investigate the association between mental health and weight gain. Regarding the association between symptoms of mental disorders and weight gain during pregnancy, no total effect was found (PC=0.043; p=0.377). Regarding indirect effects, no effect was found either through risk behaviors (PC=0.03; p=0.368) or through physical activity (PC=0.00; p=0.974). Finally, the data did not show a direct effect of symptoms of mental disorders during pregnancy such as gestational weight gain (PC=0.050; p=0.404). Gestational weight gain had no direct, indirect or total effect on symptoms of mental disorders in pregnant women.
RESUMO
Abstract We investigated whether racial discrimination accelerates the weight and Body Mass Index (BMI) gain in Blacks and Browns participants of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) in four years of follow-up. We compared body weight and BMI between the 1st (2008-2010) and 2nd visit (2012-2014) of 5,983 Blacks and Browns participants. Exposure to racial discrimination and covariates (age, sex, education, and research center) were obtained at the 1st visit. Linear mixed effects models stratified by race/skin color were used. Report of racial discrimination was more frequent among Blacks (32.1%) than Browns (6.3%). During the follow-up period, Blacks and Browns gained an average of 1.4kg and 1.2kg, respectively. This increase was greater among those who reported discrimination when compared to those who did not, both in Blacks (2.1kg vs.1.0kg, p < 0.001) and Browns (1.9kg vs. 1.1kg, p < 0.05). The results of the interaction between racial discrimination and time showed that Blacks, but not Browns, who reported racial discrimination had greater weight and BMI gains between visits. Our results suggest that reducing racial discrimination would contribute to prevent and/or control obesity increase in the country.
Resumo Investigou-se se a discriminação racial acelera o ganho de peso corporal e o Índice de Massa Corporal (IMC) em pretos e pardos participantes do Estudo Longitudinal de Saúde do Adulto (ELSA-Brasil) em quatro anos de seguimento. Comparou-se o peso corporal e o IMC entre a 1ª (2008-2010) e a 2ª visita (2012-2014) de 5.983 participantes pretos e pardos. A exposição à discriminação racial e às covariáveis (idade, sexo, escolaridade e centro de pesquisa) foram obtidas na 1ª visita. Foram utilizados modelos lineares de efeitos mistos estratificados por raça/cor da pele. O relato de discriminação racial foi mais frequente entre pretos (32,1%) do que em pardos (6,3%). Durante o período de acompanhamento, pretos e pardos ganharam uma média de 1,4kg e 1,2kg, respectivamente. Esse aumento foi maior entre os que relataram discriminação, quando comparados aos que não relataram, tanto em pretos (2,1 kg vs. 1,0 kg, p < 0,001) quanto em pardos (1,9kg vs. 1,1kg, p < 0,05). Após ajustes, os pretos, mas não os pardos, que relataram discriminação racial apresentaram maiores ganhos de peso e IMC entre as visitas. Nossos resultados sugerem que a redução da discriminação racial pode contribuir para prevenir e/ou controlar o aumento da obesidade no país.
RESUMO
Hemodialysis is the most commonly used treatment modality for end stage renal disease. A 6 months observational study was conducted in the Dialysis unit of Kasturba Hospital, Manipal to study the clinical profile, quality of life with the help of KDQoL SF 36 questionnaire and factors affecting quality of life of hemodialysis patients. A total of 45 participants were included who initiated dialysis in the year 2018 and 2019 and were receiving dialysis in our hospital. Out of 45 participant 77.8% were males and 22.2% were females, the mean age was 55.29 (11.29) years. 23 patient-initiated dialysis in the year 2018 22 patients-initiated dialysis in the year 2019. The prevalence of hypertension, diabetes mellitus and cardiovascular diseases in this population were found to be 95.2%, 35.6% and 8.9% respectively. The mean scores of the sub scales were analyzed with the help of scoring manual and descriptive statistics. In the result it was found the hemoglobin, intradialytic weight gain were found to be positively correlated with the Physical component summary (PCS) and Mental component summary (MCS). Effects of kidney disease was found to be very strongly and positively correlated with dialysis vintage. In the result of the study due to its smaller population we cannot determine more factors which were affecting the Quality of life scores.
RESUMO
Purpose: Retinopathy of prematurity (ROP) is a leading cause of childhood blindness. Capturing serial daily postnatal weight gain can act as an innovative, low?cost method of risk stratification. We aim to study the relation between weight gain in infants and occurrence of ROP. Methods: The prospective, observational study was conducted on 62 infants. ROP screening was done based on the Rashtriya Bal Swasthya Karyakram (RBSK) criteria. Infants were classified into no ROP (n = 28), mild ROP (n = 8), and treatable ROP (n = 26) groups. Average daily postnatal weight gain was measured and its relation to development of ROP was studied. All statistical calculations were done using Statistical Package for the Social Sciences (SPSS) 21 version (SPSS Inc., Chicago, IL, USA) statistical program for Microsoft Windows. Results: Mean rate of weight gain in no ROP group, mild ROP group, and treatable ROP group was 33.12, 27.19, and 15.31 g/day, respectively (P = 0.001). Mean gestational age and birth weight in treatable group (n = 26) were 31.38 weeks and 1572.31 g, respectively. Receiver operating curve analysis revealed a cutoff of 29.33 g/day for ROP and 21.91 g/day for severe ROP. Conclusion: We concluded that, babies with poor weight gain of below 29.33 g/day are at high risk for ROP and babies with wight gain of 21.91 g/day are at high risk for severe ROP. These babies should be followed meticulously. So, the rate of weight gain of a preterm can help us to prioritize babies.
RESUMO
ABSTRACT Objective: Intrauterine environment can induce fetal metabolic programming that predisposes to adiposity-related chronic diseases in its lifespan. We examined the associations of parental nutritional status and gestational weight gain with offspring body composition in early adulthood. Materials and methods: This is cross-sectional analysis of female participants of the NutriHS who were submitted to questionnaires, clinical examinations and body composition assessed by DXA. Association of pre-conception parental BMI and maternal gestational weight gain (exposures) with body composition measurements (outcomes) were analyzed using multiple linear models adjusted for Directed Acyclic Graphs-based covariables (maternal and paternal educational level, maternal age, and tobacco, alcohol and/or drugs use). The sample included 124 women (median 28 (24-31) years) with a mean BMI of 25.4 ± 4.7 kg/m2. Results: No association between previous paternal BMI and offspring's body composition was detected. In the fully adjusted linear regression model, maternal BMI was associated with offspring's total lean mass (β = 0.66, p = 0.001), appendicular skeletal muscle mass index (ASMI) (β = 0.11, p = 0.003) and fat mass index (FMI) (β = 0.03, p = 0.039). Gestational weight gain was associated with increased offspring's BMI (OR 1.12 [95% CI 1.02-1.20], p = 0.01). The linear regression model adjusted for maternal age and maternal and paternal education levels showed associations of gestational weight gain with offspring's ASMI (β = 0.42, p = 0.046), FMI (β = 0.22, p = 0.005) and android-to-gynoid fat ratio (β = 0.09, p = 0.035). Conclusion: Our findings suggest that preconception maternal BMI could influence lean mass and general adiposity of young adult female offspring and that gestational weight gain could be useful for predicting centrally distributed adiposity.
RESUMO
Abstract The aim is, systematically examine the scientific evidences that associated environmental factors (environment, social environment, environmental planning and spatial population distribution) with the excessive gestational weight gain. A meta-analysis and systematic review carried out as per the Cochrane Handbook recommendations and following the steps recommended by the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes. The inclusion studies were done with the following PECO criteria: P-pregnant women, E-environmental factors, O-weight gain. The search procedure was conducted on the databases EMBASE, Web of Science, Cinahl, LILACS and MEDLINE (PubMed). The relationship between the socioeconomic factors of the micro-region of residence and gestational weight gain was evidenced by the linkage between residing in high-poverty neighborhoods and inadequate gestational weight gain. This study revealed the higher prevalence of excessive gestational weight gain in pregnant women those lives in urban areas. Environmental factors of the pregnant women's residence area implicated in the excessive gestational weight gain. Our findings can therefore contribute to the development of public policies to prevent inadequate gestational weight gain.

RESUMO
Objective The transcriptome sequencing results of brain tissues of olanzapine-treated mice were analyzed to screen out differentially-expressed genes and explore potential targets of atypical antipsychotics leading to body weight gain.Methods Twenty female C57BL/6 mice were randomly divided into control group (Ctrl) and Olanzapine administration group (Olz), which were given saline and Olanzapine solution by gavage, respectively. The whole brain tissues were collected 8 weeks later for Transcriptome sequencing (RNA-Seq). The possible targets of olanzapine-induced body weight gain were identified by the Gene Ontology (GO) functional annotation analysis, the Kyoto Encyclopedia of Genes and Gnomes (KEGG) pathway enrichment analysis, and protein-protein interaction (PPI) network analysis. Differential expression levels of mRNAs were further verified by real-time quantitative fluorescence PCR (RT-qPCR).Results Compared with Ctrl group, 591 differentially expressed genes were screened in Olz group, including 251 up-regulated genes and 340 down-regulated genes. GO analysis showed that differential genes were widely involved in transcriptional process, among which the expression of genes related to the regulation of digestive system and cold-induced thermogenesis were significantly enriched. KEGG analysis showed that differential genes were widely involved in the interaction between neuroactive ligands and receptors, and the differential genes were significantly enriched in oxytocin signaling, fat digestion and absorption, and cholesterol metabolism pathways. RT-qPCR were performed to verify the expression levels of genes enriched in feeding regulation, gastric kinesis, thermogenesis, fat metabolism and other processes (Oxt, Trpv1, Adipoq, Phox2b, Abcg5, Mogat2, Dbh, Plac8 and Neurog1) as well as hub genes in PPI network (Fos, Dusp1 and Egr2), and the results were consistent with the trend of RNA-Seq.Conclusion Olanzapine administration resulted in changes in central feeding regulation, gastrointestinal motility, thermogenesis and other physiological processes in mice, which might be involved in body weight gain induced by olanzapine.
RESUMO
Objective:To study the impacts of pre-pregnancy body mass index (BMI), gestational diabetes mellitus (GDM) and gestational weight gain (GWG) on perinatal outcomes and mode of delivery.Methods:From November 2016 to December 2017, single-pregnancy women in early pregnancy (<13 weeks) regularly checked-up at our hospital were enrolled in this prospective cohort study and followed up until delivery. They were assigned into four groups according to pre-pregnancy BMI: obese group (≥28.0 kg/m 2), overweight group(24.0-<28.0 kg/m 2), normal group (18.5-<24.0 kg/m 2) and underweight group(<18.5 kg/m 2). A 75-g oral glucose tolerance test was performed at 24-28 weeks of pregnancy to screen for GDM. The optimal GWG was 11.0-16.0 kg for underweight group, 8.0-14.0 kg for normal group, 7.0-11.0 kg for overweight group and 5.0-9.0 kg for obesity group. The effects of pre-pregnancy BMI, GDM and GWG on perinatal outcomes and delivery mode were evaluated using multivariate logistic regression methods. Results:A total of 802 pregnant women were included. The incidences of pre-pregnancy overweight and obesity were 21.8% and 8.9%, respectively. The incidence of GDM was 14.1%. 57.2% of the participants experienced excessive GWG. The incidences of macrosomia, low birth weight and premature birth were 7.1%, 2.7% and 2.2%, respectively. The incidence of Cesarean delivery (C-section) was 37.7%. Pre-pregnancy obesity [adjusted odds ratio ( AOR)=4.355, 95% confidence interval ( CI) 1.900-9.980] and excessive GWG ( AOR=3.799, 95% CI 1.796-8.034) were independent risk factors for macrosomia. Excessive GWG was a protective factor for low birth weight ( AOR=0.279, 95% CI 0.084-0.928) and inadequate GWG was a risk factor for low birth weight ( AOR=10.954, 95% CI 3.594-33.382) and premature birth ( AOR=8.796, 95% CI 2.628-29.438). Compared with the normal group, overweight group had an increased risk of C-section ( AOR=1.817, 95% CI 1.119-2.949). Compared with pregnant women without pre-pregnancy overweight/obesity, GDM nor excessive GWG, any combination of two of the above-mentioned three factors increased the risks of macrosomia ( AOR=3.908, 95% CI 1.630-9.370) and C-section ( AOR=2.269, 95% CI 1.325-3.886). The risks of macrosomia and C-section were the highest when all three factors existed. Conclusions:Pre-pregnancy obesity and excessive GWG are independent risk factors for macrosomia and pre-pregnancy overweight is a risk factor of C-section. Exposure to any two of the three factors (pre-pregnancy overweight/obesity, GDM and excessive GWG) increases risks of macrosomia and C-section and the highest risk is observed when all three factors are present.
RESUMO
Objective:To analyze the association of pre-pregnancy body mass index (BMI) and gestational weight gain with macrosomia.Methods:In this retrospective cohort study, data of all puerperae and newborns in the Obstetrics Center of Peking Union Medical College Hospital from July 2020 to June 2021 were collected, including basic maternal information, pregnancy complications and neonatal conditions. A total of 2 422 pregnant women with full-term singleton live birth and their newborns were included in the analysis. The incidence of macrosomia (≥4 000 g) was calculated according to the birth weight of the newborns. Logistic regression and heat map were used to analyze the associations of pre-pregnancy BMI and gestational weight gain with macrosomia.Results:The incidence of macrosomia was 4.00% (97/2 422) in full-term singleton live birth newborns. Pre-pregnancy body weight, pre-pregnancy BMI, pre-pregnancy overweight/obesity rate, pre-delivery body weight, total weight gain during pregnancy, mean weekly weight gain during pregnancy, the proportion of excessive weight gain during pregnancy, duration of pregnancy, and the proportion of primiparity and education level of junior college or below were all significantly higher in the puerperae of the macrosomia group than those in the non-macrosomia group [(63.87±8.27) vs (58.14±7.86) kg, (23.33±2.97) vs (21.60±2.72) kg/m2, 35.1% vs 17.3%, (77.48±9.11) vs (70.02±8.79) kg, (13.61±4.56) vs (11.88±4.40) kg, (0.34±0.11) vs (0.30±0.11) kg, 58.8% vs 31.1%, (280.47±7.79) vs (276.14±7.83) d, 34.1% vs 23.7%, 18.6% vs 7.5%] (all P<0.05). Pre-pregnancy BMI ( OR=1.227, 95% CI: 1.145-1.314), mean weekly weight gain during the whole pregnancy ( OR=33.453, 95% CI: 5.172-217.947), duration of pregnancy ( OR=1.083, 95% CI: 1.055-1.112), primiparity ( OR=1.969, 95% CI: 1.232-3.101) and education level of junior college or below ( OR=2.525, 95% CI: 1.325-4.668) were all positively associated with occurrence of macrosomia (all P<0.05). The incidence of macrosomia increased with the pre-pregnancy body mass index and mean weekly weight gain during the whole pregnancy. Conclusions:High pre-pregnancy BMI and mean weekly weight gain during the whole pregnancy are associated with the increased risk of macrosomia. Appropriate weight management during pregnancy may help to reduce the incidence of adverse pregnancy outcomes.
RESUMO
Objective:To explore the characteristics of weekly gestational weight gain (GWG) in women with obesity and its correlation with the risk of macrosomia.Methods:Clinical data of women with singleton pregnancy and pre-pregnancy body mass index (PPBMI) ≥28 kg/m 2 were retrospectively analyzed, from January 2014 to December 2019, in Beijing Obstetrics and Gynecology Hospital, Capital Medical University (Beijing Maternal and Child Health Care Hospital). The participants were divided into three groups based on their PPBMI: group A (28-<30 kg/m 2), group B (30-<32 kg/m 2), and group C (≥32 kg/m 2). The study compared the characteristics of GWG among the three groups, explored the correlation between the weekly weight gain during each gestational stage and the risk of macrosomia, and discussed the impacts of the GWG pattern in women with different PPBMI on the risk of macrosomia. Chi-square (or Fisher's exact), Kruskal-Wallis, and Mann-Whitney U tests were performed for statistical analysis. Multivariate logistic regression was used to analyze the impact of weekly weight gain in specific gestational stages on macrosomia. Results:(1) A total of 2 046 participants were included in the study, with 982 in group A, 588 in group B, and 476 in group C. For all of the 2 046 cases, the median PPBMI was 30.1 kg/m 2 (29.0-31.9 kg/m 2), GWG was 10.5 kg (7.3-14.0 kg), and neonatal birth weight was 3 520 g (3 215-3 816 g) with 60 (2.9%) ≥4 500 g, and the biggest baby weighed 5 580 g. Out of the births analyzed, macrosomia occurred in 318 cases (15.5%). (2) Among the three groups (A, B and C), the differences in maternal age [32.0 years (29.0-35.0 years), 32.0 years (29.0-35.0 years) and 32.0 years (29.0-34.0 years), H=6.58] and women with a history of type 2 diabetes mellitus [0.9% (9/982), 0.3% (2/588) and 1.9% (9/476), χ2=6.61] were statistically significant (all P<0.05). (3) The weekly weight gain in each group exhibited a gradual upward trend before 20-24 weeks, reached a plateau at 24-32 weeks, peaked at 32-36 weeks, and subsequently declined. The weekly weight gain of group A in the pre-pregnancy to 14 weeks [0.14 kg/week (0.00-0.25 kg/week)], 14 to 20 weeks [0.25 kg/week (0.17-0.42 kg/week)], and 20 to 24 weeks [0.38 kg/week (0.25-0.63 kg/week)] were higher than those of group B [0.07 kg/week (-0.03-0.21 kg/week), 0.25 kg/week (0.10-0.42 kg/week), and 0.38 kg/week (0.22-0.60 kg/week)], respectively ( Z value was-3.73,-2.16, and-2.01, all P<0.05). Likewise, the weekly weight gain of group B in the above three stages were all higher than those of group C [0.07 kg/week (-0.10-0.21 kg/week), 0.17 kg/week (0.05-0.33 kg/week), and 0.25 kg/week (0.08-0.50 kg/week)], respectively ( Z value was-2.55,-3.28, and-3.25, all P<0.05). (4) The risk of macrosomia increased with the weekly weight gain in specific gestational stages in different PPBMI groups. In group A, the stages correlated with increased risk were 14-20 weeks [adjusted odd ratio ( aOR)=2.669, 95% CI: 1.378-5.169] and 20-24 weeks ( aOR=1.764, 95% CI: 1.143-2.723), while the stages were 20-24 weeks ( aOR=2.149, 95% CI: 1.156-3.996) and 36 weeks until delivery ( aOR=1.888, 95% CI: 1.268-2.810) in group B, and pre-pregnancy to 14 weeks ( aOR=3.515, 95% CI: 1.158-10.665) and 14-20 weeks ( aOR=3.021, 95% CI: 1.058-8.628) in group C (all P<0.05). The risk of macrosomia increased when the weekly weight gain of both risk-related stages in group A ( aOR=2.255, 95% CI: 1.029-4.940) ≥50th percentile, and group B ( aOR=4.399, 95% CI: 1.017-19.023) ≥75th percentile, and for group C ( aOR=3.404, 95% CI: 1.004-11.543) when the weekly weight gain above 25th percentile (all P<0.05). Conclusions:Weekly GWG demonstrates an observable gradual acceleration pattern in women with obesity. Therefore, clinical attention should be directed towards monitoring fluctuations in the weekly weight gain in this population, as excessive weekly weight gain before 24 gestational weeks is associated with an elevated risk of macrosomia.
