Effect of body mass index on maternal outcome in pregnancy

Background: Maternal body mass index during pregnancy is one of the important parameter which gives us the clue regarding maternal 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 obstetric outcomes in singleton pregnancies.Methods: This prospective Study was conducted over a period of 1 year from July 2019 to June 2020 on antenatal women attending OPD 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 obstetric outcome was assessed.Results: In normal BMI group 12% patients had preterm vaginal delivery. While In group of underweight patients 32% patients landed up in preterm delivery which has three times higher incidence. In overweight group 48% patients had caesarean section, while in normal BMI group it is only18% patients i.e. 3 times higher caesarean rate in high BMI group. 10% of patients belonging to normal BMI group needed induction of labor while 26% of patients in overweight group required induction .Thus incidence of induction of labor is more than double in overweight group. While only 16% patients had PPH in normal BMI group, 44% patients had PPH in overweight group i.e. three times higher. The frequency of preeclampsia was 22% in the overweight category and <1% in the normal group.Conclusions: Higher prevalence of complications to the mother when BMI is not in the recommended normal range.

Middle Eastern Population

Objective: To test the value of mid-pregnancy maternal body mass index (BMI) and weight gain in the second half of pregnancy in predicting pregnancy outcomes among Middle Eastern population where pre-gravid BMI was not available. Methods: Retrospective analysis of the obstetric outcomes of 290 women with singleton pregnancies who were categorized into underweight (UW), normal weight (NW), overweight (OW) and obese (OB) according to the BMI at 24-28 weeks of gestation and compared with recommended pre-gravid values by Institute of Medicine (2009). Results: The results showed that the gestational diabetes rate was significantly lower among the UW (2.4%) compared with the NW (8.8%, p<0.05), the OW (14.3%, p=0.006), and OB (20.5%, 0.001). The risk of having macrosomia was eight times higher among OW compared with NW women. The C-section rate was lowest among the UW group but there was no significant difference in terms C-section and low birth weight between groups. The obstetric outcomes among women whose weight gain was above the 90th and below the tenth centiles were not different. Conclusion: The prediction of obstetric outcomes by mid-pregnancy BMI is comparable to pre-gravid BMI. The results are encouraging, and further larger studies are needed to confirm the applicability

The Difference

Introduction: Blood group antigens and body mass index of human are gaining importance for many diseases. Some attempts were reported to find any relationship between BMI and Blood groups with some contradictions. The possible association between BMI and blood groups of Nepalese and Indian medical students is yet to be established. Methods: Blood groups, ABO and Rh systems and body mass index (BMI) of participants, medical students of Nepalese and Indian origin were determined and analyzed statistically. Results: The distribution frequencies of 10.56%, 17.08%, 3.06%, and 20.28% females and 9.03%, 16.39%, 3.61% and 20.0% males of both the countries were present in A, B, AB and O blood groups, respectively. Rh-negative participants were predominantly present in O blood group. The observed frequencies of participants with different BMI group were distributed as 56.11%, 24.72%, 10.69% and 8.47% in Normal, Overweight, Underweight and Obese groups, respectively. Underweight participants were prevalent in O group and in females. The difference between the distribution of Nepalese females and males with Normal BMI was found significant in A and O. A distribution pattern of B>O>A>AB was observed for Overweight group. The occurrence of Obese is few folds higher among Indian participants than Nepalese and prevalent in males. Obese participants were found more associated with B and O blood group. Conclusions: Participants with A were more prevalent among Nepalese in respect to Indian. Rh-negative participants were distributed as 1.67% and 5.0% in Nepalese and Indians, respectively and predominantly present in O (4.44%) and are more prevalent in Indian males. In Normal BMI Nepalese were significantly more as compared to Indians. In the Underweight group females were significantly more prevalent as compared to males and found maximally associated with O blood group and most of them are Nepalese. In Overweight group males were more than females. Participants with obesity were mostly present in B and O blood group and most of them are Indian.
