Indian Journal of Public Health. 2005 Oct-Dec; 49(4): 248-9http://imsear.searo.who.int/handle/123456789/109978A retrospective cohort study was undertaken among 100 women workers of 35-40 years of age to elicit the risk of spontaneous abortion. Comparison was made with a matched control group of 100 non-working women. Employed women were found at increased risk of spontaneous abortion than the control group. The difference was found statistically significant at p < 0.05, Odds ratio being 1.50 and AR% being 33.14. According to gravidity also, abortion was found to be significantly raised in working women after their joining service for first 3rd - 4th gravida. The risk then fell, to raise again for 8th or more gravida.engAbortion, Spontaneous --etiologyAdultCohort StudiesEmploymentFemaleGravidityHumansMiddle AgedPhysical ExertionPregnancyRetrospective StudiesWomen, WorkingJournal Article
