Obstructive sleep apnea (OSA) is a condition that has been proven to have significant effects on the human body. This study is a pilot study in our State that will seek to identify the prevalence of OSA in pregnancy in New Mexico.


One hundred women in our rural outreach perinatal clinics were given the Berlin questionnaire in order to determine how many of them have symptoms of OSA. Maternal demographics including age, weight, height, and gestational age were analyzed. T tests were used for continuous variables, chi-square for dichotomous variables, and logistic regression analysis to assess for correlation.


Eighty four patients successfully completed the questionnaire. Sixteen questionnaires were not completed or were missing vital information. The mean age was 30.49 years, the mean height was 1.61 m (SD 0.06 m), the mean weight was 81.51 kg (SD 20.05), and the mean body mass index (BMI) was 31.44 (SD 8.18). In our sample, 26 women (30.9%) had a positive OSA screen. Unexpectedly, there was no correlation between the number of positive screening questions and BMI, (correlation coefficient, r=0.29), or between maternal age and BMI (r=0.10).


In a high risk pregnancy clinics in New Mexico, around 30% of obese, pregnant women had symptoms consistent with OSA at around 20 weeks of gestation. This study provides researchers cause to further investigate the prevalence of OSA in pregnancy in New Mexico and, subsequently, its impact on the mother and fetus.
