BACKGROUND: Underweight is still prevalent in developing countries like India. Prepregnancy body
mass index (BMI) is used as the standard against which the measurements are made in pregnancy.
AIM: To study the association between early pregnancy BMI and feto‑maternal outcome among
nulliparous women
METHODOLOGY: This is a prospective observational study, with a sample size of 294. The antenatal
patients were categorized into four categories of BMI according to the WHO classification, and
pregnancy outcomes were compared. Data were analyzed using SPSS Software Version 17.0.
Statistical tools used were percentages and mean, and categorical variables were analyzed by
Chi‑square statistics.
RESULTS: 48.94% of the patients enrolled in the study had normal early pregnancy BMI, and 44.22%
and 6.8% were underweight and overweight, respectively. Obese women who gained more weight
were at a higher risk of preterm delivery, cesarean section, and more time required for resumption
of normal routine. Underweight women were at higher risk of postterm delivery, low birth weight,
and increased hospital stay.
CONCLUSION: Adverse maternal and fetal outcomes are seen more commonly with the extremes
of BMI.
