Objective: To examine the relationship between the intensity of physical activity of pregnant women with preterm birth and to know the relationship between types of physical activity of pregnant women with preterm birth. Methods: This research was a case-control study that was conducted at Dr. Cipto Magunkusumo Hospital and Karawang Hospital in January 2017 to June 2017 with KPAS questionnaire which was divided into two groups, preterm birth and term birth. The sample size was 127 subjects for each group. The analysis was done by multivariate analysis of the etiologic concept. Results: In term birth, the most frequent physical activity intensities were: moderate intensity (64.6%, n = 82), light intensity (22%, n = 28), and vigorous intensity (13.4%, n = 17). In preterm birth, the most frequent physical activity intensities were: light intensity (40.1%, n = 51), vigorous intensity (33.9%, n = 43), and moderate intensity (26%, n = 33). Adjusted OR of preterm birth in light intensity versus moderate intensity was OR 5.32 (95% CI, 2.80-10.13; p = < 0.001). While adjusted OR of preterm birth in vigorous intensity compared with moderate intensity was OR 6.29 (95% CI, 3.2813.46; p = < 0.001). Work and sport have a significant association with preterm birth with OR 3.19 (95% CI, 1.62 6.28; p = 0.001) and OR 1.85 (95% CI,1.11 3.09; p= 0.017). Occupational conditions are also associated with preterm birth, including: weight lifting with OR 5.16 (95% CI, 1.10-24.08, p = 0.021), walking with OR 3.57 (95% CI, 1.61-7.92, p = 0.001), sitting with OR 2.79 (95% CI, 1.23-6.31, p = 0.011), and standing with OR 3.04 (95% CI, 1.40-6.59; p = 0.003). Conclusion: There is a significant relationship between the intensity of physical activity and type of physical activity in pregnant women with preterm birth.
