IP Innovative Publication Pvt. Ltd., 2017
Objective: To study body mass index in pregnant women, to correlate body mass index in pregnancy with obstetrics outcome and to correlate body mass index in pregnancy with perinatal outcome. Materials and Method: Women attending antenatal OPD for antenatal check up at SSMC, Tumkur from January 2015 to June 2016 will be included after informed written consent. The above were placed in standard BMI categories and their obstetric outcomes and perinatal outcome variables were evaluated. Results: Increased rate of LSCS was associated with high BMI group 41.67% (n=20) when compared to normal 16.67 % (n=6) p=0.013, Significant. Increased rate of Hypothyroid was associated with high BMI group 12.5 % (n=6) when compared to normal 2.77% (n=1) p=0.109, significant. Increased rate of GDM was associated with high BMI group 20.83%(n=10) when compared to normal 8.34%(n=3)p=0.058, significant. Increased rate of GHTN was associated with high BMI group 20.83% (n=10) when compared to normal 8.34% (n=3) p=0.058, significant. Increased rate of in NICU admission was associated with underweight group 37.5% (n=6) when compared to normal 8.34% (n=3)p=0.000214, significant. Increased rate of anaemia was associated with underweight group 56.25% (n=10) when compared to normal 27.77% (n=10) p=0.04, significant. Conclusion: Body Mass Index plays a significant role in adverse pregnancy outcome. High BMI is associated with increased incidence of hypothyroid, gestational diabetes mellitus, gestational hypertension, instrumental delivery, caesarean delivery. There is significant association of underweight BMI with anaemia, low birth weight.
Effect of body mass index on fetal outcome in pregnancy
Indian Journal of Obstetrics and Gynecology Research, 2021
Maternal body mass index during pregnancy is one of the important parameter which gives us the clue regarding fetal complications. The objectives of this study were to study distribution of antenatal patients in underweight, normal, overweight (and obese) categories according to booking BMI, to examine the association of BMI with perinatal outcomes in singleton pregnancies. This prospective Study was conducted over a period of 1 year from July 2019 to June 2020 on antenatal women attending O.P.D in the Department of Obstetrics and Gynecology in LLRM Medical College. The enrolled patients were divided into three equal groups(n=50) according to their BMI. In all the groups perinatal outcome was assessed. The mean baby birth weight for whole study group was 2.807 kg with standard deviation of 0.44. Birth weight found to be related to maternal BMI and mother with low BMI have babies with low birth weight and vice versa.14% of babies born to mothers belonging to underweight BMI group req...
Body Mass Index Changes during Pregnancy and Perinatal Outcomes - A Cross-Sectional Study
Revista Brasileira de Ginecologia e Obstetrícia / RBGO Gynecology and Obstetrics
Objective To evaluate the relation between changes the body mass index (BMI) percentile, reflected in the Atalah curve, and perinatal outcomes. Methods A cross-sectional study with 1,279 women was performed. Data regarding gestational weight, sociodemographic characteristics and perinatal outcomes were collected through medical charts, prenatal card and interviews in the postpartum period. Women could be classified according to the Atalah curve in the following categories: low weight, adequate weight, overweight, and obese. The BMI was calculated at the first and at the last prenatal care visits, and these values were compared. Results An increase in the BMI category according to the Atalah classification occurred in 19.9% of pregnant women, and an increase of 3.4, 5.8 and 6.4 points of BMI were found for women respectively classified in the adequate weight, overweight and obese categories at the first prenatal visit. Women with high school education presented a lower chance of incr...

In the last few decades the prevalence of overweight and obesity has reached epidemic levels worldwide affecting over 2.1 billion people, including a large proportion of women of childbearing age. An adverse intrauterine environment resulting from conditions such as maternal obesity or gestational diabetes, can have long-term negative effect on the child's health later in life. This study focuses on maternal pre-pregnancy BMIs and their association with biochemical profile in pregnancy, delivery mode and size of neonates in the Croatian Islands’ Birth cohort Study (CRIBS). A total of 301 mother-child dyads were included in this study. The classification of the pre-pregnancy nutritional status followed WHO BMI cut-offs. Blood samples of women were taken in the second trimester of pregnancy and analysed for fasting blood glucose level, urates, creatinine, uric acid, total protein, bilirubin, triglycerides, total cholesterol, HDL and LDL cholesterol, potassium, sodium, aspartate tr...

Introduction: Maternal nutrition plays an important role in maternal and fetal outcomes. The low maternal BMI or Obesity are both associated with adverse outcomes. Objectives: To evaluate the impact of the maternal body mass index on the pregnancy outcome and neonatal outcomes. Materials and Methods: This is a prospective cohort study in which a total of 200 patients meeting the inclusion criteria were enrolled in the study after informed consent of which 100 patients enrolled after 18 weeks of gestation had a low BMI and 100 patients with a higher BMI than normal. Results: Pregnant females having low BMI as baseline had more risk of IUGR, fetal distress and low birth weight in newborns while those having high maternal BMI had more incidence of PIH in mothers, oigohydramnios, increased birth weight, increased risk of LSCS and NICU admisisions and delayed maternal wound healing. Conclusion: The health of women, throughout their childbearing ages, should be addressed, to improve their obstetrical and perinatal outcomes. Also, the high risk groups should be managed at tertiary centres.

BACKGROUND Maternal overweight/obesity causes many complications during pregnancy and delivery. It can also increase neonatal and infant morbidity and mortality. BMI is an important measure of under/overweight. This observational study examines the correlation between maternal Body Mass Index (BMI) with maternal outcome in women. MATERIALS AND METHODS This study was conducted at Department of Obstetrics and Gynaecology, Government Medical College, Kottayam, Kerala, for a period of one year. A sample of 300 pregnant women with intrauterine pregnancy of gestational age <12 weeks at first visit was taken for this study with an age between 18 and 35 years with singleton pregnancy. BMI of these women were calculated and they were classified into two categories (BMI <23 kg/m 2 and BMI ≥23 kg/m 2). The Chi-square test was done to find the association of BMI and various maternal outcomes. RESULTS In the sample of 300 pregnant women, 39% were having BMI <23 kg/m 2 and 61% were having BMI ≥23 kg/m 2. Pregnant women with BMI ≥23 kg/m 2 were found to have significantly increased risk of developing gestational hypertension, gestational diabetes and macrosomia. We found that a significantly increased need of induction and increased risk of developing intrapartum and postpartum complications in those with BMI ≥23 kg/m 2. Our study also found out that an increased incidence of elective as well as emergency caesareans and increased risk of neonatal complications in women whose BMI ≥23 kg/m 2. CONCLUSION Adverse maternal and perinatal outcomes are significantly related to extremes of BMI categories and least complications were seen in normal BMI group. Therefore, it is ideal to reduce the body weight to an optimal level so that the complications, which are attributed to overweight and obesity can be reduced. We recommended future research on the association of BMI and maternal outcomes involving large samples comparable to those done in developed countries.
Second Trimester Body Mass Index (BMI) as a Predictor of Adverse Maternal and Perinatal Outcome
Obstetrics & Gynecology International Journal, 2016
Objective: This study was undertaken to evaluate whether BMI estimation in the second trimester is predictive of adverse maternal and neonatal outcomes and whether it can be used as a clinically relevant screening tool. Design & Setting: This retrospective study was conducted at a tertiary care teaching hospital from May 2012 to April 2015. Population: Low risk women with singleton pregnancies who had presented to the hospital for the first time in their second trimester of pregnancy were recruited. Methods: BMI was calculated and all patients were followed up and outcomes noted. Nomogram was prepared for the study population. BMI less than 5 th centile was taken as 'underweight' and BMI more than 95 th centile as 'obese'. Main outcome measures: Maternal outcomes included gestational hypertension and preeclampsia, gestational diabetes, preterm delivery, caesarean delivery and postpartum haemorrhage. Results: There was a significant increase in gestational hypertension, preeclampsia, gestational diabetes, large for gestational age neonate in women with BMI above the 95 th centile. Low birth weight were common in women with BMI < 5 th centile. Conclusion: The present study highlights that both ends of the spectrum of BMI are correlated with adverse outcomes in pregnant women. Hence it is important to record maternal height and weight even when they present in the second trimester. This simple parameter which does not need any specialised equipment can easily triage women. Significance: Many women present to the healthcare providers in second trimester. The availability of pre-pregnancy or first trimester BMI cannot be totally relied upon. Thus we may miss out on an important predictor of pregnancy outcome. This study was undertaken to evaluate whether BMI estimation in the second trimester is predictive of adverse maternal and neonatal outcomes and whether it can be used as a clinically relevant screening tool.

Background Maternal body mass index (BMI) below or above the reference interval (18.5–24.9 kg/m2) is associated with adverse pregnancy outcomes. Whether BMI exerts an effect within the reference interval is unclear. Therefore, we assessed the association between adverse pregnancy outcomes and BMI, in particular within the reference interval, in a general unselected pregnant population. Methods Data was extracted from a prospective population-based multicentre cohort (Risk Estimation for PrEgnancy Complications to provide Tailored care (RESPECT) study) conducted between December 2012 to January 2014. BMI was studied in categories (I: <18.5, II: 18.5–19.9, III: 20.0–22.9, IV: 23.0–24.9, V: 25.0–27.4, VI: 27.5–29.9, VII: >30.0 kg/m2) and as a continuous variable within the reference interval. Adverse pregnancy outcomes were defined as composite endpoints for maternal, neonatal or any pregnancy complication, and for adverse pregnancy outcomes individually. Linear trends were asses...
