title: Adverse pregnancy outcomes in rural Maharashtra, India (2008-09): a retrospective cohort study.
abstract: BACKGROUND
  The study was carried out to record adverse pregnancy outcomes and to obtain information about sex ratio at birth in rural especially tribal areas in the State of Maharashtra, India. Although the tribal population is considered vulnerable to innumerable adversities, regretfully information about pregnancy wastage among them is not available. About 10% population of the state is tribal. The study of sex ratio at birth was planned as the overall sex ratio and child sex ratio had declined in the state.
  
  
  METHODS
  The cohort of antenatal cases registered in rural areas of Maharashtra in the calendar year 2008 was followed up to study the pregnancy outcomes. A retrospective study was carried out from October 2009 to August 2010. The outcomes of all the registered antenatal cases were recorded by the Auxiliary Nurse Midwives. The summary sheets were obtained by Block Medical Officers. The data was entered at the block level by trained data entry operators in specially designed web-based software. Adverse pregnancy outcome was categorized in two groups abortions and stillbirths.
  
  
  RESULTS
  About 1.1 million registered pregnancies were followed up. In the state 5.34% registered pregnancies ended in abortions. In tribal PHCs the relative risk of spontaneous abortion and induced abortion was 0.91 and 0.38 respectively. It was also revealed that about 1.55% pregnancies culminated in stillbirth. The relative risk of stillbirths in tribal PHCs was 1.33. The sex ratio at birth in the state was 850. The ratio was 883 in the tribal PHCs. Correlation was observed between sex ratio at birth and induced abortion rate.
  
  
  CONCLUSIONS
  The study indicates that women from tribal PHCs are exposed to higher risk of adverse pregnancy outcome in the form of stillbirths. In non-tribal areas high induced abortion rate and poor sex ratio at birth is observed. These two indicators are correlated. The correlation may be explained by the unscrupulous practice of sex selective abortion.
