Methodology: We prepared a cross-sectional study in one of educational
hospitals (Fatemieh's Hospital) in Hamadan city in the west of Iran. Two hundred
women were included in this study. Weight and body mass index was
measured in pre-pregnancy state and again at 6 months postpartum. Effective
factors in postpartum weight loss were assessed. The questionnaire included
age, education, employment, parity, doing exercise, type of delivery, newborn
weight and BMI at 6 months after delivery.
Results: Mean age of study participants was 23.3±5.21 years and mean parity
was 1.62±0.7. The overall average BMI was 24.2±3.3 before pregnancy and
25.5±3.4 six months after delivery. Pregnant women had an increase in weight
of 12.1±3.5 kg and mean weight loss was 6.2 ± 2.9 kg at six months postpartum.
Multiple regression analysis revealed that age was having p value 0.001, parity
(p value 0.005), height (p value 0.01), gestational weight gain (p value 0.001),
pre pregnancy BMI (p value 0.001), type of delivery (p value 0.03) and exercise
(p value 0.04).
Conclusion: Parameters such as age, parity, exercise, type of delivery, height
and gestational weigh gain were significantly associated with postpartum
