Association between maternal weight gain during pregnancy and child's body mass index at preschool age.

BACKGROUND: Recent studies reported that prepregnancy body mass index (BMI) and weight gain during pregnancy affect birth weight and contribute to childhood obesity. However, no such data are available in Korea. PURPOSE: This study gathered data on weight gain during pregnancy and its impact on birth weight and childhood obesity in Korea. METHODS: We reviewed 1,753 singleton full-term babies born at CHA Bundang Medical Center in 2014-2016. We first review each maternal and baby factor based on prepregnancy BMI (underweight, normal, overweight/obese) and then divided them into low, normal, and excess gestational weight gain (GWG) groups based on the American Institute of Medicine (IOM) guidelines. We reviewed the characteristics of each group and analyzed the association between maternal GWG based on IOM guidelines and child BMI after 6 years. RESULTS: The maternal prepregnancy BMI group showed a significant difference in birth weight and child BMI at 6 years. As the prepregnancy BMI increased, the birth weight and BMI at 6 years also increased (P<0.001). Mean birth weight and child BMI at 6 years differed significantly among the GWG groups. Furthermore, excess postpartum weight gain increased the risk of childhood overweight and obesity (odds ratio, 2.21; 95% confidence interval, 1.40-3.49). CONCLUSION: Excess weight gain during pregnancy should be avoided due to its short- and long-term association with childhood obesity. Owing to the high prevalence of excess GWG and childhood obesity, excess weight gain during pregnancy can have significant public health implications.

Weight retention 12 months postpartum: association with sociodemographic, gestational and puerperal factors / Retenção de peso 12 meses pós-parto: associação com fatores sociodemográficos, gestacionais e puerperais

Abstract Objectives: to investigate the association between sociodemographic, gestational/puerperal factors and postpartum weight retention (PPWR) after 12 months in Brazilian women at a university hospital. Methods: prospective cohort with puerperal women recruited at the maternity ward of a university hospital in a Brazilian metropolis. At baseline (n=260), sociodemographic and anthropometric information on the mother-child binomial and data related to the gestational period were collected. Maternal dietary patterns were measured using a food frequency questionnaire and subsequently determined by Principal Component Analysis. Results: 75 women, with a mean age of 28.4 years (CI95%= 27.0-29.7), 25.3% with excessive PPPR, with an average of 3.6 kg (CI95%= 1.7) continued in the follow-up. -5.4). Higher gestational weight gain (GWG) (ß= 0.36; CI95%= 0.18-0.70) and lower maternal age (ß= -0.41; CI95%= -0.92--0.22) were PRPP predictors (p=0.001) (adjusted for per capita income, parity, type of delivery, number of prenatal visits, baby's birth weight, breastfeeding and physical activity). Conclusion: there was a high occurrence of excessive PPPR, favored by higher GPG and lower maternal age. This highlights the importance of monitoring women's health during the reproductive period, with guidance on ways of life (diet and physical activity), to favor better outcomes for mother-child.

Resumo Objetivos: investigar a associação entre fatores sociodemográficos, gestacionais/puerperais com a retenção de peso pós-parto (RPPP) após 12 meses em mulheres brasileiras em hospital universitário. Métodos: coorte prospectiva com puérperas recrutadas na maternidade do hospital universitário de uma metrópole brasileira. Na linha de base (n=260) foram coletadas informações sociodemográficas, antropométricas do binômio mãe-filho e dados relativos ao período gestacional. O padrão alimentar materno foi mensurado por meio do questionário de frequência alimentar e posteriormente determinado pela Análise de Componentes Principais. A RPPP foi classificada como risco para obesidade se ≥7,5Kg. Resultados: 75 mulheres continuaram no seguimento, com média de 28,4 anos de idade (IC95%= 27,0−29,7), 25,3% com RPPP excessiva, sendo em média 3,6 Kg (IC95%= 1,7−5,4). Maior ganho de peso gestacional (GPG) (β= 0,36; IC95%= 0,18-0,70) e menor idade materna (β= −0,41; IC95%= −0,92--0,22) foram preditores da RPPP (p≥0,001) (ajustado pela renda per capita, paridade, tipo de parto, número de consultas pré-natal, peso ao nascer do bebê, aleitamento materno e atividade física). Conclusão: evidenciou-se elevada ocorrência de RPPP excessiva, favorecida pelo maior GPG e menor idade materna. Aponta-se assim a importância do monitoramento da saúde da mulher durante o período reprodutivo, com orientações sobre modos de vida (alimentação e atividade física), para favorecer melhores desfechos para mãe-filho.

Strengthening maternal nutrition counselling during routine health services: a gap analysis to guide country programmes.

OBJECTIVE: The WHO recommends counselling on healthy eating, weight gain, and physical activity during antenatal care (ANC) and postnatal care (PNC), yet advice and information are often not tailored to women's nutritional needs and contexts. The purpose of the gap analysis was to identify key elements related to the provision of maternal nutrition counselling during routine health contacts and provide programme considerations to strengthen quality service delivery. DESIGN: A search of PubMed, Cochrane Library, CINAHL Plus and Scopus databases was conducted to retrieve studies from January 2010 to December 2021. Using inclusion criteria, quantitative, qualitative and mixed methods studies were included in the final gap analysis. SETTING: Low-, middle- and high-income country contexts. PARTICIPANTS: Following application of gap analysis criteria, thirty-seven articles from sixteen countries were included in the analysis. RESULTS: Gaps in delivery of maternal nutrition counselling include provider capacity building, frequency, content and delivery platforms. Globally, counselling on appropriate weight gain during pregnancy is often not delivered with the desired content nor quality, while targeted counselling to overweight and obese women was provided in several high-income country contexts. Delivery of maternal nutrition counselling through multiple delivery platforms demonstrated improvements in maternal diet and/or weight gain during pregnancy. CONCLUSIONS: Strengthening the integration of maternal nutrition counselling into pre- and in-service curricula, routine health provider training, supportive supervision and provider mentoring is needed. Future efforts may consider generating global and regional weight gain guidelines and incorporating maternal nutrition counselling indicators as part of quality-of-care ANC/PNC standards and routine health systems.

Plasma concentrations of leptin at mid-pregnancy are associated with gestational weight gain among pregnant women in Tanzania: a prospective cohort study.

BACKGROUND: Gestational weight gain (GWG) has critical implications for maternal and child health. Inflammation and angiogenesis are implicated in various aspects of maternal metabolism that may play a role in gestational weight gain. The associations of inflammatory, angiogenic, and metabolic pathways with GWG are yet to be elucidated. This study evaluated associations between a panel of inflammatory, angiogenic, and metabolic proteins measured in mid-pregnancy and gestational weight gain. METHODS: Pregnant women were enrolled from Dar es Salaam, Tanzania, between 2001 and 2004. The participants were enrolled at mid-pregnancy (12 to 27 weeks of gestation) and followed up until delivery. This analysis focused on a cohort of 1002 women who were primigravid, had singleton live births, had longitudinal measures of gestational weight, and whose mid-pregnancy plasma samples underwent analysis for 18 proteins. RESULTS: Higher plasma concentrations of leptin (mean difference in GWG percent adequacy comparing highest with lowest quartiles: 10.24; 95% CI 3.31, 17.16; p-trend = 0.003) and chitinase-3-like protein-1 (CH3L1) (mean difference in GWG percent adequacy comparing highest with lowest quartiles: 7.02; 95% CI 0.31, 13.72; p-trend = 0.007) were associated with greater GWG in a dose-response pattern. Higher leptin concentrations were associated with a lower risk of inadequate GWG (risk ratio comparing highest with lowest quartiles: 0.77; 95% CI 0.65, 0.91; p-trend = 0.001) and a higher risk of excessive GWG (risk ratio comparing highest with lowest quartiles: 1.57; 95% CI 1.03, 2.39; p-trend = 0.03). Higher CH3L1 concentrations were associated with a higher risk of excessive GWG (p-trend = 0.007). The associations of leptin and CH3L1 with inadequate GWG were stronger during the second than the third trimester. The other 16 proteins examined were not significantly associated with GWG. CONCLUSIONS: Mid-pregnancy plasma leptin concentrations may be associated with GWG and have clinical predictive utility in identifying women at a higher risk of inadequate or excessive gestational weight gain.

Características maternas asociadas al diagnóstico de macrosomía fetal en un hospital III-1 de la capital de Perú / Maternal Characteristics Associated With The Fetal Macrosomy Diagnosis In A Hospital III-1 Of The Capital Of Peru

Objetivo: Identificar cuáles son las características maternas asociadas al diagnóstico de macrosomía fetal en el Hospital Sergio E. Bernales de enero a diciembre del 2018. Métodos: Se realizó un estudio de tipo observacional, analítico, retrospectivo, de casos y controles. La población estudiada fueron las gestantes con el diagnostico de macrosomía fetal atendidas en el servicio de ginecoobstetricia del Hospital Sergio E. Bernales enero a diciembre del 2018. A través de una ficha de recolección de datos, se extrajo la información de las historias clínicas, las cuales después fueron procesadas según el programa de IBM SPSS Statistics v25. Resultados: De 532 pacientes estudiados se obtuvieron 133 casos y 399 controles. La edad materna varía entre 14 y 45 años (edad media de 27,01). Se encontró asociación estadísticamente significativa entre macrosomía fetal y las siguientes variables: embarazo postérmino (OR=13,613 IC95% 2,901-63,891), diabetes gestacional (OR 5,7 IC95%2,5 -12,7), ganancia de peso excesiva (OR 1,833 IC95%1,154-2,911), sexo del recién nacido (OR 1,83 IC95%1,2-2,7) y edad de la madre (OR 1,7 IC95%1,0-2,9). Al realizar el análisis multivariado no se encontró asociación con las variables edad de la madre (P =0,228, OR 1,510 IC95%0,773- 2,950) e IMC (P=0,331, OR 0,740 IC95%0,403-1,358), por lo que se consideraron variables confusoras. Conclusión: Las características maternas asociadas al diagnóstico de macrosomía fetal son parto postérmino, diabetes gestacional, ganancia de peso excesiva y sexo del recién nacido.

Objective: To identify the maternal characteristics associated with the diagnosis of fetal macrosomia at Sergio E. Bernales Hospital from January to December 2018. Methods: An observational, analytical, retrospective, case-control study was carried out. The population studied was pregnant women with a diagnosis of fetal macrosomia treated in the gynecoobstetrics service of Sergio E. Bernales Hospital from January to December 2018. Through a data collection sheet, the information from the medical records was extracted; the data was then processed according to the IBM SPSS Statistics v25 program. Results: Of 532 patients studied, 133 cases and 399 controls were obtained. Maternal age varies between 14 and 45 years (average age of 27.01). A statistically significant association was found between fetal macrosomia and the following variables: post-term pregnancy (OR = 13,613 95% CI 2,901-63,891), gestational diabetes (OR 5.7 IC95% 2.5 -12.7), excessive weight gain (OR 1,833 95% CI 1,154-2,911), sex of the newborn (OR 1.83 95% CI 1.2-2.7) and age of the mother (OR 1.7 95% CI 1.0-2.9). When performing the multivariate analysis, no association was found with the variables age of the mother (P = 0.228, OR 1.510 95% CI 0.773-2.950) and BMI (P = 0.331, OR 0.740 95% CI 0.403-1.358), so they were considered confusing variables. Conclusion: The maternal characteristics associated with the diagnosis of fetal macrosomia are post-term delivery, gestational diabetes, excessive weight gain and sex of the newborn.

Associations of maternal gestational weight gain with the risk of offspring obesity and body mass index Z scores beyond the mean.

PURPOSE: We examined the association of meeting the 2009 Institute of Medicine gestational weight gain (GWG) guidelines with offspring obesity and body mass index Z score (BMIZ) at age six overall and by maternal weight status. METHODS: Data were from the Infant Feeding Practices Survey II Study (2005-2007) and their Year Six Follow-Up Study (2012). Logistic regression and quantile regression models were used. RESULTS: Eleven percent of children were obese. Children born to mothers who gained excessive weight during pregnancy had an increased risk of obesity as compared with those born to mothers who gained adequate weight (adjusted odds ratio: 1.67). The association was stronger among normal-weight mothers (adjusted odds ratio: 3.50). Inadequate GWG was not associated with offspring obesity overall or in subsamples by maternal prepregnancy BMI. Children born to mothers who gained excessive weight had higher BMIZ. This distributional association was more pronounced among normal-weight mothers. Children born to obese mothers who gained inadequate weight had lower BMIZ at some percentiles of the BMIZ distribution. CONCLUSIONS: Excessive GWG was associated with increased risk of offspring obesity and higher BMIZ at age six, whereas inadequate GWG was protective of high BMIZ among children born to obese mothers.

ARE THE FACTORS AFFECTING ADVERSE PREGNANCY OUTCOMES DIFFERENT IN OBESE GESTATIONAL DIABETES PREGNANT WOMEN RECEIVING DIET OR INSULIN TREATMENT?

CONTEXT: We aimed to examine the factors affecting adverse gestational outcome in gestational diabetes (GDM) patients, who were grouped as obese and normal- weight, having only-diet, or insulin treatments. SUBJECTS AND METHODS: The study included 373 patients, treated with diet or insulin. These patients were sub-grouped as obese and non-obese, and examined retrospectively. The variables affecting adverse gestational outcome in obese GDM patients having dietary and/ or insulin treatments were detected with multiple regression analysis. RESULTS: The weight gained during pregnancy in the GDM group having insulin treatment was more than the one in only-diet treated GDM group (p=0.004). Pre-pregnancy body mass index, the weight gained during pregnancy, hemoglobin A1C levels in the second and third trimesters, caesarian rates were higher in the insulin-treated obese patients than in the other groups (p<0.001). The odds ratio for fasting blood glucose level in insulin-treated obese GDM group was 1.081 (95% CI =1.004 - 1.163) (p=0.039); and it was 0.982 (95% CI =0.924 - 1.002) (p=0.048) for the weight gained during pregnancy, in only-diet treated obese GDM patients. CONCLUSION: The control of weight gained during pregnancy, and of fasting blood glucose levels in obese patients having GDM, is important to decrease adverse gestational outcome.

[Nutritional Status of Japanese Women of Childbearing Age and the Ideal Weight Range for Pregnancy].

According to the recent 2015 Nutrition Survey, the prevalence of being underweight (Body Mass Index, BMI <18.5 kg/m2) among women in their 20s is 22.3%. Women of childbearing age tend to have a lower intake of protein and their total energy intake is lower than the requirements established by the 2015 Dietary Reference Intakes for Japanese. There is a growing body of evidence showing that underweight women tend to bear small babies and that these babies have an increased risk of diabetes or cancer in their adulthood. In order to prevent Japanese women from bearing small babies, the literature has suggested that women of childbearing age should be encouraged to remain at a normal weight before pregnancy. For optimal weight gain during pregnancy, existing guidelines recommend different ranges of weight gain based on prepregnancy BMI. Owing to the absence of official GWG recommendations in Asian countries, including China and Taiwan, the US Institute of Medicine (IOM) guidelines are generally followed. However, Asian women are smaller and experience lower weight gains; therefore, excessive weight gain may lead to harmful events including macrosomia, preterm birth, preeclampsia, gestational diabetes, pregnancy-induced hypertension, and short- and long-term postpartum weight retention. Thus, an accurate GWG range should be determined for Asian women. We introduce one epidemiological study in which the optimal weight gain range was investigated by analyzing receiver-operating characteristic curves together with potential research ideas in this field with the aim of encouraging young researchers to solve this public health problem affecting mothers and children.

Program considerations for integration of nutrition and family planning: Beliefs around maternal diet and breastfeeding within the context of the nutrition transition in Egypt.

In Egypt, rising maternal overweight and obesity is consistent with the transition to westernized diets and a growing reliance on energy-dense, low nutrient foods. Although the first 1,000 days of life are the focus of many programmes designed to prevent many forms of malnutrition, little attention has been paid to maternal dietary practices and weight gain during pregnancy. This study used in-depth interviews with pregnant women (N = 40), lactating women (N = 40), and nonlactating women (N = 40) to gain an understanding of behaviours, perceptions, and cultural beliefs in relation to maternal dietary intake during pregnancy, lactation, and nonlactation; weight gain during pregnancy; birth spacing; and family planning. Study findings reveal that food choice was driven by affordability, favoured foods, or foods considered appropriate for a specific life stage (pregnant, lactating, and nonlactating). Knowledge of weight gain during pregnancy is limited, especially with regards to excessive weight gain during pregnancy. Diet is often modified during lactation to support breast milk production, and a normal diet resumed when breastfeeding ceases. Within the context of breastfeeding, the lactational amenorrhea method provides an opportunity to improve exclusive breastfeeding practices, maternal diet during lactation, and the transition to other family planning methods by 6 months postpartum. Health care providers should discuss limiting maternal consumption of low nutrient foods such as junk foods, soda, and teas during pregnancy and postpartum. Dietary counselling should accompany information on appropriate weight gain during pregnancy and exercise to prevent excessive weight gain, in the context of the nutrition transition.

Higher adherence to Mediterranean diet prior to pregnancy is associated with decreased risk for deviation from the maternal recommended gestational weight gain.

The present retrospective study was conducted on 1482 women in order to evaluate whether their pre-pregnancy adherence to the Mediterranean diet may affect maternal gestational weight gain (GWG). For this purpose, the study population was classified according to the Institute of Medicine (IOM) recommendations concerning GWG. Pre-pregnancy adherence to the Mediterranean diet was assessed with 11 food patterns groups based on their contribution in the Mediterranean diet pyramid. Women with high adherence to the Mediterranean diet were more frequently characterised by GWG inside the IOM recommendations. In multivariate analysis, women with low Mediterranean diet adherence were almost twice at risk in presenting deflection from recommended GWG regardless of various confounding factors. These findings suggested that high pre-pregnancy adherence to the Mediterranean diet may be associated with reduced risk for GWG outside the IOM recommendations. However, larger prospective studies are strongly recommended in order for more precise conclusions to be drawn.

Addressing barriers to maternal nutrition in low- and middle-income countries: A review of the evidence and programme implications.

Adequate maternal nutrition during the "first 1,000 days" window is critical from conception through the first 6 months of life to improve nutritional status and reduce the risk of poor birth outcomes, such as low birthweight and preterm birth. Unfortunately, many programmes have targeted implementation and monitoring of nutrition interventions to infants and young children, rather than to women during pregnancy or post-partum. A literature review was conducted to identify barriers to food choice and consumption during pregnancy and lactation and to examine how low- and middle-income countries have addressed maternal nutrition in programmes. A literature review of peer-reviewed and grey literature was conducted, and titles and abstracts reviewed by authors. Twenty-three studies were included in this review. Barriers to adequate nutrition during pregnancy included cultural beliefs related to knowledge of quantity of food to eat during pregnancy, amount of weight to gain during pregnancy, and "eating down" during pregnancy for fear of delivering a large baby. Foods considered inappropriate for consumption during pregnancy or lactation contributed to food restriction. Drivers of food choice were influenced by food aversions, economic constraints, and household food availability. Counselling on maternal diet and weight gain during pregnancy was seldom carried out. Programming to support healthy maternal diet and gestational weight gain during pregnancy is scant. Tailored, culturally resonant nutrition education and counselling on diet during pregnancy and lactation and weight gain during pregnancy, as well as monitoring of progress in maternal nutrition, are areas of needed attention.

Caracterización clínica de lactantes menores de un año, con excesiva ganancia de peso durante la alimentación con leche materna / Clinical features of infants younger than one year with excessive weight gain while being breast fed

Introducción: La lactancia materna es recomendada como fuente de alimentación optima para los primeros meses de vida. En nuestro Servicio hemos recibido un grupo particular de niños alimentados con lactancia materna exclusiva, que muestran aumento excesivo de peso desde el primer semestre de vida. Objetivo: describir las características clínicas de un grupo de lactantes menores de un año, con aumento excesivo de peso y alimentación con lactancia materna. Población y métodos: estudio observacional, prospectivo y longitudinal. Incluimos todos los niños menores de un año derivados al servicio de Nutrición entre 2003 y 2015, con lactancia materna exclusiva durante los primeros 6 meses, persistencia de la misma al momento de la evaluación y peso- edad mayor a 2 desvíos estándar (DS). Describimos características clínicas y de laboratorio de los lactantes y sus madres, así como el patrón alimentario que pudiera explicar esta inusual ganancia de peso. Resultados: incluimos 73 lactantes, 63% niñas. El 64% tenía peso-talla mayor a 2DS a los 3 meses de vida y el 100% a los 6 meses. No se pudo establecer patrón hambresaciedad. El 44% de las madres aumentó más de 18 kilogramos durante el embarazo. Las niñas nacidas de las madres que habían aumentado más de 18 Kg fueron significativamente más grandes al nacer. En el 14% de los lactantes se encontró alguna enfermedad de base. De toda la muestra, el 75% presentó anemia y el 14.5% hipotiroidismo. Conclusiones: describimos un grupo de lactantes con aumento excesivo de peso desde los primeros 3 meses de vida que se mantiene durante toda la etapa de lactancia materna. Diferentes factores como relación madre-hijo, patrón alimentario, composición de la leche humana, predisposición genética; podrían haber contribuido con este patrón de crecimiento.(AU)

Introduction: Maternal breastfeeding is recommended as the best source of nutrition in the first months of life. At our Department we have seen a group of exclusively breastfed children who showed excessive weight since the first semester of life. Objective: To describe the clinical features of a group of infants under one year of age with excessive weight gain while being breast-fed. Population and methods: A prospective, longitudinal, observational study was conducted. We included all infants under one year of age who were referred to the Department of Nutrition between 2003 and 2015, who were exclusively breastfed during the first 6 months of life and were still being breastfed at the moment of the evaluation, and who had a weight-for-age of more than 2 standard deviation (SD). We describe the clinical and laboratory features of the infants and their mothers, as well as feeding patterns that may explain this unusual weight gain. Results: We included 73 infants, 63% girls. Overall, 64% had a weight-for-height greater than 2 SD at 3 months of life and 100% at 6 months of life. No hunger-satiety pattern could be established. Of the mothers, 44% gained more than 18 kg during the pregnancy. The girls born from mothers who had increased more than 18 Kg were significantly larger at birth. In 14% of the infants, an underlying disease was found. Of all the infants in the sample, 75% had anemia and 14.5% hypothyroidism. Conclusions: We describe a group of infants with excessive weight gain in the first 3 months of life which was maintained throughout the maternal breastfeeding period. Different factors, such as the motherchild relationship, feeding pattern, human milk composition, and genetic predisposition may have contributed to this particular growth pattern. (AU)

Participant Characteristics in the Kumamoto University Regional Center of Japan Environment and Children's Study (JECS): Association of Pregnancy Outcomes with Pregestational Maternal Body Mass Index and Maternal Weight Gain during Pregnancy.

PURPOSE: The purpose of this study was to identify participant characteristics in the Kumamoto University Regional Center of the Japan Environment and Children's Study (K-JECS) and to investigate the association of pregnancy outcomes with pregestational maternal body mass index (BMI) and maternal weight gain during pregnancy (MWG). METHODS: The subjects were women with singleton birth, who had been recruited by the K-JECS, and were registered in the data systems for the first and second questionnaires and transcripts of medical records. The subjects were categorized by BMI with further classification by MWG. The chi-squared test and one-way analysis of variance were performed to determine the correlations of BMI and MWG with perinatal outcomes. Logistic regression analysis was performed to examine perinatal outcome risks. RESULTS: The subject characteristics were similar to the trends observed in the Japanese general population. The odds ratio for natural delivery was low in the overweight groups (OW) and normal weight groups (NW) with excessive weight gain. On the other hand, the risk of cesarean section was high in the OW, and risk of induced or accelerated delivery was high in the NW with excessive weight gain. The risks of preterm birth and LBW were high in the insufficient weight gain groups regardless of BMI. The risks of pregnancy-induced hypertension and gestational diabetes were high in the OW.

Association of maternal pre-pregnancy weight, weight gain during pregnancy, and smoking with small-for-gestational-age infants in Japan.

AIM: The aim of this study was to evaluate the associations of maternal pre-pregnancy body mass index (BMI), weight gain during pregnancy, and smoking, with small-for-gestational-age (SGA) births among Japanese women. MATERIALS AND METHODS: Subjects were pregnant women who gave birth to single, term infants (37-42 weeks) at a clinic and hospital in the Nagasaki area between 2012 and 2013. To examine associations with SGA, 49 underweight (BMI<18.5 kg/m(2)) and 579 normal-weight (18.5 ≤ BMI<25.0 kg/m(2)) Japanese women with either appropriate-for-gestational-age or SGA infants were selected and analyzed. RESULTS: The prevalence of SGA infants was 6.8%. Seven percent of women were current smokers. Prevalence of pre-pregnancy underweight and gestational weight gain less than recommendation were 20.8% and 16.7%, respectively. Multivariate logistic regression was performed to assess factors affecting SGA infants in the pregnant women. After adjusting for covariates, the amount of maternal weight gain below recommendation (odds ratio (OR), 2.72; 95% confidence interval (CI), 1.37-5.39) and maternal smoking status (OR, 2.80; 95% CI, 1.14-6.91) were significantly and independently associated with SGA births. Pre-pregnancy maternal weight status showed a borderline association (OR, 1.91; 95% CI, 0.96-3.83, p=0.067). CONCLUSION: To prevent SGA births, education regarding the adequate nutrition and the adverse effect of maternal smoking is important for the women of reproductive age.

[Prevention of shoulder dystocia risk factors before delivery]. / Prévention des facteurs de risque de la dystocie des épaules avant l'accouchement.

OBJECTIVE: To determine whether it is possible to prevent the occurrence of risk factors for shoulder dystocia before or during pregnancy. METHODS: The PubMed database, the Cochrane Library and the recommendations from the French and foreign obstetrical societies or colleges have been consulted. Studied measures were exercise before or during pregnancy, dietary management, and gestational diabetes management in obese and non-obese patients. RESULTS: No study has proven that the correction of these risk factors (except gestational diabetes) would reduce the risk of shoulder dystocia. In the general population, physical exercise is recommended either before or during pregnancy to reduce the risk of gestational diabetes (physical activity before pregnancy) (grade B), fetal macrosomia (grade C) or maternal weight gain during pregnancy (grade C). No dietary regimen is recommended to reduce these issues (grade B). In overweight or obese (body mass index [BMI]>25), physical activity coupled with dietary management is recommended (grade A) because it reduces fetal macrosomia (EL1). In addition, it allows a modest reduction in maternal weight gain during pregnancy (EL2), but did have an effect on the occurrence of gestational diabetes (EL1). In case of gestational diabetes, diabetes care is recommended (diabetic diet, glucose monitoring, insulin if needed) (grade A) as it reduces the risk of macrosomia and shoulder dystocia (EL1). The recommended weight gain during pregnancy is 11.5 kg to 16 kg for normal BMI patients (grade B). Obese patients should be aware of the importance of controlling their weight gain during pregnancy (professional consensus). It is recommended that patients regain their pre-conception weight, and ideally a BMI between 18 and 25 kg/m(2), 6 months postpartum (grade B) to reduce the risk of gestational diabetes and macrosomia in a subsequent pregnancy (EL2). CONCLUSION: Physical activity is recommended before and during pregnancy to reduce the occurrence of risk factors for shoulder dystocia. In obese patients, physical activity should be coupled with dietary measures to reduce fetal macrosomia and weight gain during pregnancy.

Crecimiento pre y postnatal asociados a sobrepeso corporal en escolares de Bayamo / Pre and postnatal growth as related to overweight among Bayamo school-age children

OBJETIVO: identificar la asociación entre factores prenatales y relacionados con el primer año de vida y su influencia en el sobrepeso corporal de edades ulteriores. MÉTODOS: se realizó un estudio observacional, retrospectivo, analítico, de casos y controles en el municipio Bayamo con 200 escolares con sobrepeso corporal y 200 niños normales de 6-11 años de edad, de la misma zona de residencia, nacidos de madres con similar edad gestacional de 37-42 semanas, homogéneos en edad y sexo y con historia de no afecciones de salud. En el análisis estadístico se estimó el riesgo asociado como Odd Ratio. RESULTADOS: se mostró una fuerte asociación entre el sobrepeso corporal en la edad escolar y la ganancia de peso excesiva en los primeros 4 meses de vida, bajo peso, reducida longitud supina y circunferencia cefálica en el momento del nacimiento y hábito de fumar, insuficiente ganancia de peso corporal, bajo IMC y enfermedades de la madre durante el embarazo. CONCLUSIONES: estos factores deben ser considerados en la prevención de la obesidad infantil. La ganancia de peso acelerada en los primeros meses de vida de niños nacidos con afectación del crecimiento fetal debe ser prevenida.

OBJECTIVE: describe the relationship between prenatal factors and those occurring during the first year of life, and determine their influence on overweight in later stages. METHODS: an analytical observational retrospective case-control study was conducted in the municipality of Bayamo with 200 overweight school-age children and 200 normal children aged 6-11 years from the same area of residence, born to mothers with similar gestational age of 37-42 weeks, homogeneous as to age and sex, and with a history of good health. The statistical analysis included estimation of the associated risk as odd ratio. RESULTS: a strong association was found between overweight at school age and the following factors: excessive weight gain during the first 4 months of life, low weight, reduced supine length and head circumference at birth, smoking, insufficient weight gain, low BMI and maternal diseases during pregnancy. CONCLUSIONS: these factors should be borne in mind in the prevention of child obesity. Rapid weight gain during the first months of life should be prevented among children born with fetal growth disorders.

Aplicación de las referencias nacionales para la evaluación antropométrica de las embarazadas en la vigilancia nutricional en Cuba / Implementation of national references for the anthropometry assessment of pregnants in the nutritional surveillance in Cuba

Introducción: la vigilancia del estado nutricional materno se lleva a cabo en Cuba desde el año 1979, pero nunca se había podido disponer de referencias propias del país para gestantes. Objetivos: comparar el estado nutricional de las embarazadas utilizando las referencia cubanas y las del Instituto de Medicina de los Estados Unidos de Norteamérica (IOM) 1990. Métodos: usando como información base los sitios centinelas para la vigilancia nutricional materna se valoró siguiendo los puntos de corte del IOM 1990 y de las referencias nacionales, el estado nutricional de las embarazadas y se obtuvo la comparación entre el índice de masa corporal (IMC) a la captación, la ganancia de peso durante la gestación según el estado nutricional inicial y la edad de las embarazadas según ambas referencias. Resultados: se pudo comprobar que existe una disminución del porcentaje de embarazadas con bajo peso al inicio de la gestación al utilizar las normas cubanas, la ganancia de peso ideal según el estado nutricional inicial es relativamente baja con el uso de ambas normas, las tablas cubanas diagnostican con más frecuencia el sobrepeso y la obesidad que las del Instituto de Medicina de los Estados Unidos de Norteamérica (IOM), las embarazadas menores de 15 años son las que presentan una mayor proporción de ganancia de peso inferior a la ideal. Se demuestra la importancia del uso de referencias propias. Conclusiones: los datos de la vigilancia del estado nutricional materno son mejor interpretados según las tablas cubanas por ser obtenidas de la misma población

Introduction: the surveillance of the maternal nutritional status is conducted in Cuba from 1979, but never has been possible to have our own references for pregnants. Objectives: to compare the nutritional status of pregnants using the Cuban references and that of the Institute of Medicine of the United States of America (IOM) 1990. Methods: using as basement information the sentinel sites for the maternal nutritional surveillance authors assessed the cut points of the IOM 1990 and of the national references of the pregnant nutritional status obtaining the comparison between the body mass index (BMI) for capture, the weight gain during pregnancy according to the initial nutritional status and the pregnant age according to both references. Results: it was possible to verify the existence of a decrease in the low weight pregnants at onset of pregnancy with the use of Cuban standards, the ideal weight gain according to the initial nutritional status is relatively low using both standards, the Cuban tables diagnose more frequently the excess weight and the obesity than that of the IOM, the pregnant aged under 15 are who have a greater ratio of weight gain lower than the ideal one. The significance of the use of own references is demonstrated. Conclusions: the data on maternal nutritional status surveillance are better interpreted according to the Cuban tables because they are obtained from the same population

Aplicación de las referencias nacionales para la evaluación antropométrica de las embarazadas en la vigilancia nutricional en Cuba / Implementation of national references for the anthropometry assessment of pregnants in the nutritional surveillance in Cuba

Introducción: la vigilancia del estado nutricional materno se lleva a cabo en Cuba desde el año 1979, pero nunca se había podido disponer de referencias propias del país para gestantes. Objetivos: comparar el estado nutricional de las embarazadas utilizando las referencia cubanas y las del Instituto de Medicina de los Estados Unidos de Norteamérica (IOM) 1990. Métodos: usando como información base los sitios centinelas para la vigilancia nutricional materna se valoró siguiendo los puntos de corte del IOM 1990 y de las referencias nacionales, el estado nutricional de las embarazadas y se obtuvo la comparación entre el índice de masa corporal (IMC) a la captación, la ganancia de peso durante la gestación según el estado nutricional inicial y la edad de las embarazadas según ambas referencias. Resultados: se pudo comprobar que existe una disminución del porcentaje de embarazadas con bajo peso al inicio de la gestación al utilizar las normas cubanas, la ganancia de peso ideal según el estado nutricional inicial es relativamente baja con el uso de ambas normas, las tablas cubanas diagnostican con más frecuencia el sobrepeso y la obesidad que las del Instituto de Medicina de los Estados Unidos de Norteamérica (IOM), las embarazadas menores de 15 años son las que presentan una mayor proporción de ganancia de peso inferior a la ideal. Se demuestra la importancia del uso de referencias propias. Conclusiones: los datos de la vigilancia del estado nutricional materno son mejor interpretados según las tablas cubanas por ser obtenidas de la misma población(AU)

Relationship between maternal weight gain and newborn's birthweight in women with normal glucose tolerance and gestational diabetes / 대한산부인과학회잡지

OBJECTIVE: The purpose of this study was to determine the independent factors that predict neonatal birthweight and find the relationship between maternal weight gain and neonatal birthweight in women with normal glucose tolerance (NGT) and gestational diabetes mellitus (GDM). METHODS: Forty-six women with GDM and one hundred fifty women with NGT were included in the study. All subjects had singleton pregnancies and no medical diseases that may affect the fetal growth and were certain of gestational age by early ultrasonography. Maternal weight at each prenatal visit was recorded and neonatal anthropometic measurement was done within 2 days of birth. RESULTS: The average rate of weight gain (kg/week) in NGT was lowest during the first trimester (0.09 +/-0.10), peaked during the second trimester (0.52+/-0.14), and slowed after 34 gestational weeks (0.46+/-0.26). In women with GDM, the average rate of weight gain was also lowest during the first trimester (0.18+/-0.23), but it was twofold higher compared with women with NGT. There was a significant decrease of the rate of weight gain after 28 gestational weeks in women with GDM. Total weight gain during pregnancy was 3.4 kg less in women with GDM. Neonatal birthweight was correlated with maternal weight gain and the rate of weight gain during 14-27 and 28-33 weeks in NGT. However, birthweight was correlated with maternal weight gain and the rate of weight gain during the first trimester and 14-27 weeks in GDM. CONCLUSION: This result suggests that the women with GDM who have greater weight gain during the first and the second trimester have a increased risk of excessive fetal growth. Thus strict glycemic control during pregnancy is needed especially in these women.
