Key result
Breech presentation (OR 9.65), female sex (OR 4.04), firstborn status (OR 1.91), and maternal age ≥25 years (OR 1.53) were identified as significant perinatal risk factors for DDH.

What are the prevalence and perinatal risk factors for developmental dysplasia of the hip in South Australia?
Odds Ratio: 9.65
Breech presentation, female sex, firstborn status, and maternal age ≥25 years are significant risk factors for developmental dysplasia of the hip, which had a prevalence of 10.5 per 1000 births in South Australia.
YIV et al. (1997) conducted a case-control in Developmental dysplasia of the hip (DDH) (n=1,236). Perinatal risk factors (e.g., breech presentation) vs. Absence of risk factors was evaluated on Perinatal risk factors for DDH (e.g., breech presentation) (OR 9.65). Breech presentation (OR 9.65), female sex (OR 4.04), firstborn status (OR 1.91), and maternal age ≥25 years (OR 1.53) were identified as significant perinatal risk factors for DDH.
