AB0969 GAINED WEIGHT DURING PREGNANCY AND LOW BACK PAIN: IS IT REALLY ASSOCIATED?

Background: Back pain is known to be a common complaint during pregnancy explained by gained weight in this period. Besides, the incidence of low back pain (LBP) in postpartum has also been quoted to be non-negligible even after delivery. Objectives: The aim of our study was to assess if the development of LBP during the post-partum period was correlated to gained weight after delivery. Methods: In this prospective study, we assessed a survey of 60 women under the age of 35 for back pain symptoms during the postpartum period from day 1 to 18 months. A structured questionnaire using Google form was used. Data from this survey were then correlated with gained weight and pregnancy outcome, as well as women’s history of LBP. Results: We interviewed 60 women during their post-partum period. The mean age was 27,9 years old [24, 35 years]. Women were on average at 9 months of post-partum [1, 18 months]. The median height was 1,6 meters [1,54-1,74m]. The median weight at the moment of the study was 63,2 kilograms [48-80kg]. Before pregnancy, body mass index was 23,5 Kg/m2 [17-34 Kg/m2]. The total gained weight at the end of pregnancy was 14 kg [12-29 kg]. Only 20% gained more than 15kg. LBP was experienced in 35% of cases with a mean delay of 3,2 months post-partum [1-8 months]. The prevalence of persistent LBP was noted in 26% of cases. However, no correlation was found between LBP and gained weight (p=0,07). Sixty five percent reported one or more significant episodes of back pain during their pregnancy. Significantly, more patients suffering from pain in pregnancy had history of previous back pain episodes when not pregnant (p<0,001), as well as during previous pregnancies (p<0,001). Conclusion: No correlation was found between gained weight and occurrence of LBP. The main factors associated with the development of back pain were previous episodes of back pain while non-pregnant or pregnant. Disclosure of Interests: None declared
