Fatores socioeconômicos, clínicos e nutricionais no ganho de peso interdialítico em usuários de hemodiálise / Factores socioeconómicos, clínicos y nutricionales en el aumento de peso interdialítico en usuarios de hemodiálisis / Socioeconomic, clinical and nutritional factors on interdialytic weight gain in haemodialysis users

Resumo Objetivo Avaliar os fatores associados ao ganho de peso interdialítico em usuários de serviços de hemodiálise em uma Região Metropolitana do Brasil. Métodos Estudo epidemiológico transversal envolvendo 1.024 indivíduos com doença renal crônica em hemodiálise no Brasil. O ganho de peso interdialítico foi avaliado pelo percentual de ganho de peso entre uma sessão de hemodiálise e outra. As variáveis incluídas na análise de regressão logística binária foram selecionadas considerando p< 0,10 no teste bivariado. Resultados Demonstramos que ter mais anos de estudo (OR=0,537;IC 95% = 0,310-0,931; p=0,027) e sobrepeso (OR=0,661;IC 95% = 0,461-0,948; p=0,024) ou obesidade ( OR=0,387;IC 95% = 0,246-0,608; p=<0,001) reduziu as chances de os usuários apresentarem alto ganho de peso interdialítico. Usuários sem trabalho remunerado (OR=2,025; IC 95% = 1,218-3,365; p=0,007) e que não adotavam medidas para reduzir o sal (OR=1,694; IC 95% = 1,085-2,645; p=0,020) tiveram maiores chances de ganho de peso interdialítico. Conclusão Os resultados apontam para associação entre o aumento do ganho de peso interdialítico e a ausência de trabalho remunerado e a não adoção de medidas para reduzir a ingestão de sal na dieta. Portanto, o conhecimento sobre esses fatores associados pode ser uma alternativa importante para o direcionamento individualizado dessa população.

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.

Effect of Moringa olifera leaves on growth and gut microbiota of Nile tilapia (Oreochromis niloticus) / Efeito das folhas da Moringa olifera no crescimento e na microbiota intestinal da tilápia do Nilo (Oreochromis niloticus)

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.

Resumo O estudo foi conduzido para avaliar o efeito da Moringa olifera no crescimento e saúde intestinal da tilápia (Oreochromis niloticus). A ração com 30% de proteína bruta foi preparada como dieta experimental com 4%, 8% e 10% de suplementação de folhas de M. olifera, respectivamente. A dieta controle foi desprovida de folhas de M. olifera. O ensaio de alimentação de 10 semanas foi realizado em 60 peixes em aquários. O peixe pesava 3% do peso corporal duas vezes ao dia. A dieta com alto nível de inclusão de folhas de M. olifera aumentou significativamente a taxa de crescimento, taxa de sobrevivência (SR), taxa de crescimento de sobrevivência (SGR) e eficiência de conversão alimentar (FCE) em todos os grupos de tratamento em comparação com o grupo de controle. 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.

Impact of anthro-metabolic indices and gestational weight gain on maternal and neonatal outcomes: a prospective observational study

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.

Sintomas depressivos, ansiedade e os sintomas estressantes durante a gravidez afetam o ganho de peso gestacional? / Do depressive symptoms, anxiety and stressful symptoms during pregnancy affect gestational weight gain?

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.

Racial discrimination predicts the increase in body weight and BMI in Black individuals from ELSA-Brasil cohort / Discriminação racial prediz o aumento do peso corporal e do IMC em indivíduos pretos da coorte ELSA-Brasil

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.

Clinical Profile and Quality of Life of Incident Hemodialysis Patients

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.

Study to evaluate the relation between weight gain in infants and occurrence of retinopathy of prematurity

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.

Parental body mass index and maternal gestational weight gain associations with offspring body composition in young women from the Nutritionists' Health Study

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.

Environmental factors associated with excessive gestational weight gain: a meta-analysis and systematic review / Fatores ambientais associados ao ganho de peso gestacional excessivo: uma meta-análise e revisão sistemática

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 O objetivo é examinar sistematicamente as evidências científicas que associam fatores ambientais (meio ambiente, meio ambiente social, planejamento ambiental e distribuição espacial da população) com o excessivo ganho de peso gestacional. Trata-se de uma revisão sistemática e meta-análise realizada seguindo os passos recomendados pelo Preferred Reporting Items for Systematic Reviews and Meta-Analyzes. Os estudos de incluídos basearam-se nos seguintes critérios PECO: P-gestantes, E-fatores ambientais, O-ganho de peso gestacional. O procedimento de pesquisa foi conduzido nas bases de dados EMBASE, Web of Science, Cinahl, LILACS e MEDLINE (PubMed). A relação entre os fatores socioeconômicos da microrregião de residência e o ganho de peso gestacional foi evidenciada pela ligação entre a residência em bairros de alta pobreza e o ganho de peso gestacional inadequado. Este estudo revelou a maior prevalência de ganho de peso gestacional excessivo em gestantes que vivem em áreas urbanas. Fatores ambientais da área de residência das gestantes implicados no ganho de peso gestacional excessivo. As descobertas desse estudo podem, portanto, contribuir para o desenvolvimento de políticas públicas para evitar o ganho de peso gestacional inadequado.

Weight gain in patients starting Dolutegravir-based ART according to baseline CD4 count after 48 weeks of follow up

ABSTRACT Background: Excessive weight gain is a current concern among People Living with HIV (PLHIV) starting ART. Objectives: To evaluate the weight gain after 48-weeks of ART in naive patients, according with baseline CD4 count. Methods: PLHIV starting 3TC + TDF + DTG with at least 48-weeks of follow up in two AIDS referral centers were stratified by baseline CD4 count (lower or higher than 200 cells/mm3). Data on CD4 count, HIV viral load, weight/Body Mass Index (BMI), lipids and glucose levels were collected at baseline, 24 and 48 weeks of treatment. For analysis purpose, patients were categorized according to their BMI progression. Results: A total of 270 patients were included in the study. Mean CD4 count were 78.3 ± 61.7 and 536.7 ± 273 cells/mm3 for low and high CD4 count groups, respectively (p < 0.001). Baseline BMI was significantly lower in low CD4 group (21.7 vs. 23.6 Kg/m2, p < 0.001). Patients in low CD4 group gained more weight than those in high CD4 group (11.2 ± 8.5 kg vs. 2.2 ± 4.2 Kg, p = 0.004). Overall weight gain was higher in women, regardless group (13.1 ± 7.9 Kg vs. 1.4 ± 3.6 Kg for women and men, respectively, p < 0.001). The proportion of overweight/obesity significantly increased in low CD4 group. Viral suppression rate was high for both groups. At week 48 the overall proportion of overweight/obesity was like that reported for the Brazilian population. Conclusions: Weight gain in the present study indicates a "return to health" phenomenon. Excessive weight gain was more frequent in women.

Depressive and eating disorders in patients post-bariatric surgery with weight regain: a descriptive observational study / Transtorno depressivo e alimentar em pacientes pós-bariátricos cirurgia bariátrica com reganho de peso: um estudo observacional descritivo

ABSTRACT BACKGROUND: Although bariatric surgery is today's gold standard treatment for obesity, weight regain affects the success rate of the procedure. Recent studies have identified psychiatric and neurological factors as possible causes. AIMS: The aim of this study was to evaluate the influence of psychiatric diseases on the outcome and long-term success of bariatric surgeries and find a weight regain threshold that has an acceptable sensibility to mental health-related issues to be used in research and clinical studies. METHODS: This is a observational study of bariatric patients submitted to Roux-en-Y bypass or sleeve gastrectomy, with a postoperative time of 2-10 years to access weight regain, depression, and binge-eating disorder. RESULTS: Of 217 patients studied, 163 were women and 54 were men, with an average postoperative time of 5.2±2.6 years. Weight regain was experienced in 35% of the patients, binge-eating disorder in 24.9%, and depression in 24%. The greater weight before surgery, body mass index (BMI), percentage increase to maximum weight loss, and time postoperatively all have a significant positive correlation with weight regain (p=0.045, p=0.026, p<0.001, and p<0.001, respectively). A significant association between binge-eating disorder, depression, and anxiety with weight regain (p=0.004, p=0.008, and p=0.001, respectively) was found. CONCLUSIONS: The significant weight regain rates with significant impact on psychiatric disorders highlight the need for continuous postoperative monitoring focused on the psychiatric aspects of obesity to aid surgeries' long-term success.

RESUMO INTRODUÇÃO: Embora a cirurgia bariátrica atualmente é considerada o tratamento padrão ouro para a obesidade, o reganho de peso afeta a taxa de sucesso do procedimento. Estudos recentes identificaram fatores psiquiátricos e neurológicos como possíveis causas. OBJETIVOS: Avaliar a influência de transtornos psiquiátricos no resultado a longo prazo das cirurgias bariátricas; testar a sensibilidade e correlação das fórmulas de reganho de peso e de seus respectivos pontos de corte para questões relacionadas à saúde mental. MÉTODOS: Estudo observacional de pacientes pós bariátricos submetidos à by-pass em Y de Roux ou gastrectomia vertical com pós-operatório de 2 a10 anos avaliados quanto a reganho de peso, depressão e transtorno da compulsão alimentar. RESULTADOS: Foram avaliados 217 pacientes, 163 mulheres e 54 homens com pós-operatório de 5,2±2,6 anos. O reganho de peso foi registrado em 35% dos pacientes, o transtorno da compulsão alimentar (TCA) foi encontrado em 24,9% e depressão em 24%. O ganho de peso pré-operatório, o índice de massa corporea (IMC), o aumento percentual para perda máxima de peso e tempo de pós-operatório, apresentaram correlação positiva significativa com o reganho de peso (p=0,045), (p=0,026), (<0,001), (<0,001). Foi encontrada associação significativa entre TCA, depressão e ansiedade com reganho de peso (p=0,004), (p=0,008) e (p=0,001). CONCLUSÕES: As taxas significativas de reganho de peso associado ao impacto dos transtornos psiquiátricos reforçam a necessidade de acompanhamento pós-operatório contínuo focado nos aspectos psiquiátricos da obesidade, para sucesso do tratamento cirúrgico em longo prazo.

Intimate partner physical violence and inadequate weight gain in pregnancy / Violência física entre parceiros íntimos e ganho de peso inadequado durante a gestação

Abstract Objectives: to evaluate the association between intimate partner physical violence (IPPV) and inadequate gestational weight gain (GWG). Methods: cross-sectional study composed of 554 women who attended four Basic Health Units in the city of Rio de Janeiro between 2005 and 2009. The GWG was calculated through the difference between the final weight of pregnancy and pre-gestational weight. For the measurement of IPPV, the Portuguese version of the Conflict Tactics Scales (CTS-1) was used. Data analysis was based on multinomial logistic regression models, estimating odds ratios and respective 95% confidence intervals for associations between the variables of interest. Results: the prevalence of minor and severe IPPV was 31.6% and 16.3%, respectively. Almost two-thirds of the women had insufficient or excessive GWG. After adjusting the model, it was observed that the presence of IPPV increased by 1.66 (CI95%=1.05-2.64) times the chances of insufficient GWG, compared to couples who did not experience this type of violence. Concerning the excessive GWG, the associations with IPPV were not statistically significant. Conclusion: women who experience IPPV in their relationships are more likely to have insufficient GWG during pregnancy. From this perspective, prenatal care becomes an essential service for screening domestic violence and its possible repercussions.

Resumo Objetivos: avaliar a associação entre violência física entre parceiros íntimos (VFPI) e o ganho de peso gestacional (GPG) inadequado. Métodos: estudo seccional composto por 554 mulheres que compareceram a quatro Unidades Básicas de Saúde do município do Rio de Janeiro, entre 2005 e 2009. O GPG foi calculado através da diferença entre o peso final da gestação e o peso pré-gestacional. Para a mensuração da VFPI foi utilizada a versão em português da Conflict Tactics Scales (CTS-1). A análise dos dados se baseou em modelos de regressão logística multinomial, estimando-se razões de chance e respectivos intervalos de 95% de confiança para as associações entre as variáveis de interesse. Resultados: a prevalência de VFPI menor e grave foi 31,6% e 16,3%, respectivamente. Quase dois terços das mulheres apresentaram GPG insuficiente ou excessivo. Após o ajuste do modelo, observou-se que a presença de VFPI aumentou em 1,66 (IC95%=1,05-2,64) vezes as chances de GPG insuficiente, em comparação aos casais que não vivenciaram este tipo de violência. Em relação ao GPG excessivo as associações com VFPI não foram estatisticamente significantes. Conclusões: mulheres que vivenciam a VFPI têm maiores chances de apresentarem GPG insuficiente. Nessa perspectiva, o pré-natal passa a ser um serviço fundamental para o rastreamento de violência doméstica e suas possíveis repercussões.

Birth-to-childhood tracking of linear growth and weight gain in the MINA-Brazil Study / Autocorrelação do crescimento linear e ganho de peso do nascimento à infância no Estudo MINA-Brasil

ABSTRACT OBJECTIVE: To investigate birth-to-childhood tracking of linear growth and weight gain across the distribution of length/height and weight for age z-scores and according to household wealth. METHODS: Data from 614 children from the MINA-Brazil Study with repeated anthropometric measurements at birth and up to age five years were used. Z-scores were calculated for length/height (HAZ) and weight (WAZ) according to international standards. Birth-to-childhood tracking was separately estimated using quantile regression models for HAZ and WAZ, extracting coefficients and 95% confidence intervals (95%CI) at the 25th, 50th, and 75th quantiles. In a subgroup analysis, we estimated tracking between birth and age two years, and between ages two and five years. To investigate disparities in tracking, interaction terms between household wealth indexes (at birth and age five years) and newborn size z-scores were included in the models. RESULTS: Tracking coefficients were significant and had similar magnitude across the distribution of anthropometric indices at age five years (HAZ, 50th quantile: 0.23, 95%CI: 0.11 to 0.35; WAZ, 50th quantile: 0.31, 95%CI: 0.19 to 0.43). Greater tracking was observed between ages two and five years, with coefficients above 0.82. Significantly higher tracking of linear growth was observed among children from wealthier households, both at birth, at the lower bounds of HAZ distribution (25th quantile: 0.30, 95%CI: 0.13 to 0.56), and during childhood, in the entire HAZ distribution at five years. For weight gain, stronger tracking was observed at the upper bounds of WAZ distribution at age five years among children from wealthier households at birth (75th quantile: 0.59, 95%CI: 0.35 to 0.83) and during childhood (75th quantile: 0.54, 95%CI: 0.15 to 0.93). CONCLUSION: There was significant tracking of HAZ and WAZ since birth, with indication of substantial stability of nutritional status between ages two and five years. Differential tracking according to household wealth should be considered for planning early interventions for preventing malnutrition.

RESUMO OBJETIVO: Investigar a autocorrelação do crescimento linear e ganho de peso do nascimento até a infância considerando a distribuição de escores z de comprimento/estatura e peso por idade e de acordo com a riqueza domiciliar. MÉTODOS: Foram utilizados dados de 614 crianças do Estudo MINA-Brasil com medições antropométricas realizadas do nascimento até os cinco anos de idade. Escores z foram calculados para comprimento/estatura (HAZ) e peso (WAZ) seguindo padrões internacionais. A autocorrelação ou estabilidade da adequação do estado nutricional do nascimento à infância foi estimada por meio de modelos de regressão quantílica para HAZ e WAZ, separadamente, extraindo-se coeficientes e intervalos de confiança de 95% (IC95%) nos quantis 25, 50 e 75. Em uma análise de subgrupo, estimou-se a autocorrelação entre o nascimento até os dois anos de idade, e entre dois e cinco anos de idade. Para investigar disparidades na autocorrelação, termos de interação entre índices de riqueza familiar (ao nascer e aos cinco anos de idade) e escores z de tamanho do recém-nascido foram incluídos nos modelos. RESULTADOS: Os coeficientes de autocorrelação foram significantes e tiveram magnitude semelhante ao longo da distribuição dos índices antropométricos aos cinco anos de idade (HAZ, quantil 50: 0,23, IC95%: 0,11 a 0,35; WAZ, quantil 50: 0,31, IC95%: 0,19 a 0,43). Maior estabilidade do estado nutricional foi observada entre dois e cinco anos, com coeficientes acima de 0,82. Autocorrelação significantemente maior do crescimento linear foi observada entre as crianças de domicílios mais ricos, tanto ao nascer, nos limites inferiores da distribuição HAZ (quantil 25: 0,30, IC95%: 0,13 a 0,56) e durante a infância, em toda a distribuição HAZ aos cinco anos. Para o ganho de peso, observou-se uma autocorrelação mais forte nos limites superiores da distribuição do WAZ aos cinco anos de idade entre as crianças de domicílios mais ricos ao nascer (quantil 75: 0,59, IC95%: 0,35 a 0,83) e durante a infância (quantil 75: 0,54, IC95%: 0,15 a 0,93). CONCLUSÃO: Houve autocorrelação significante de HAZ e WAZ desde o nascimento, com indicação de substancial estabilidade do estado nutricional entre os dois e cinco anos de idade. A autocorrelação diferencial de acordo com a riqueza domiciliar deve ser considerada para o planejamento de intervenções precoces para prevenir a má nutrição.

Effects of excessive weight gain during pregnancy on offspring health: a review / 预防医学

@#Excessive gestational weight gain has already become a global clinical and public health problem that seriously affects maternal health. Excessive gestational weight gain not only increases the cesarean section rate and induces adverse pregnant outcomes, but also affects offspring development and health. This article reviews the effects of excessive weight gain during pregnancy on offspring health and its underlying mechanisms. Excessive gestational weight gain may increase the risk of obesity, cardiovascular diseases, infectious diseases of the respiratory tract, diabetes, polycystic ovary syndrome, mental or psychological illness among offspring, and the pathophysiological mechanisms include inflammatory response, intestinal flora dysbiosis and epigenetics theory. However, further studies are required to validate these hypotheses and to evaluate the effect of excessive weight gain at different gestational stages on offspring health, so as to provide insights into reasonable management of weight gain during pregnancy and improvements of offspring health.

Weekly gestational weight gain in women with obesity and its association with risk of macrosomia / 中华围产医学杂志

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.

Association of pre-pregnancy body mass index and gestational weight gain with macrosomia / 中华健康管理学杂志

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.

Factors affecting excessive weight gain during pregnancy / 预防医学

Objective@#To investigate the current prevalence of excessive weight gain during pregnancy among pregnant and lying-in women in Xining City and to identify the influencing factors, so as to provide insights into reasonable weight control during pregnancy.@*Methods@#The pregnant and lying-in women who were registered and delivered in the Red Cross Hospital of Qinghai Province, the Affiliated Hospital of Qinghai University and the First People's Hospital of Xining City from August 2021 to July 2022 were enrolled. Women's demographics, health status during pregnancy, diet, sleep and exercise were collected through prenatal testing data and questionnaires. Excessive weight gain during pregnancy was identified according to "Weight monitoring and evaluation during pregnancy of Chinese Women" (T/CNSS 009-2021), and the factors affecting excessive weight gain during pregnancy were identified using a multivariable logistic regression model.@*Results@#A total of 902 questionnaires were allocated and 882 valid questionnaires were recovered, with an effective recovery rate of 97.78%. The pregnant and lying-in women had a mean age of (29.06±4.16) years, mean pregestational body mass index of (20.44±2.20) kg/m2 and mean gestational weight gain of (14.17±3.11) kg, and there were 447 primiparas (50.68%) and 360 women with excessive weight gain during pregnancy (40.82%). Multivariable logistic regression analysis identified an educational level of senior high school/technical secondary school (OR=1.400, 95%CI: 1.037-1.889), annual household income of >200 000 Yuan (OR=2.385, 95%CI: 1.924-2.956), a family history of diabetes (OR=1.475, 95%CI: 1.180-1.844), pregestational overweight/obesity (OR=4.079, 95%CI: 2.471-6.734), gestational hypertension (OR=2.061, 95%CI: 1.027-4.136), anxiety (OR=1.315, 95%CI: 1.139-1.518) and preference for sour foods (OR=1.715, 95%CI: 1.237-2.376) as risk factors for excessive weight gain during pregnancy, and early pregnancy reaction as a protective factor (OR=0.636, 95%CI: 0.546-0.742).@*Conclusions @#The prevalence of excessive weight gain during pregnancy was high in Xining City, and educational level, annual household income, family history of diabetes, pregestational body mass index, pregnant complications and dietary habits are factors affecting excessive weight gain during pregnancy.

Impacts of pre-pregnancy body mass index, gestational diabetes mellitus and gestational weight gain on perinatal outcomes and mode of delivery / 中国新生儿科杂志

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.
