The effect of sedentary behavior during pregnancy on premature rupture of membrane in women above 35 years old.

Background: Sedentary life is now considered among the main health risks globally among general population and pregnant women. Premature rupture of membranes is a serious pregnancy condition that is a main cause of newborn morbidity and death globally. There is very limited data about the effect of sedentary behavior during pregnancy on premature rupture of membranes.

Aim and objectives: The current study set out to evaluate the impact of sedentary behavior during pregnancy on premature rupture of the membranes in women older than 35.

Setting and methods: A cohort prospective study was done on 90 pregnant women at Kasr Al-Ainy Hospitals. Participants were met three times (once per trimester). Routine labs and examinations were done and physical activities and sedentary behavior were assessed using prenatal physical activity questionnaire at each visit then pregnant women were followed up till rupture of membranes happened.

Results: A statistically significant difference was observed in the kind and intensity of physical activity among pregnant individuals at the first, second, and third trimesters. Women who experienced premature rupture of membranes demonstrated significantly lower levels of physical activity (household or caregiving, occupational, and low physical activities) and they also showed signs of a more sedentary lifestyle.

Conclusion: Sedentary behavior during pregnancy had great effect on premature rupture of membranes in women above 35 years old. Sedentary participants were twice as likely to develop premature rupture of membranes in contrast to individuals who don't engage in sedentary behavior.
