How is women's demand for caesarean section measured? A systematic literature review

Background Caesarean section rates are increasing worldwide, and since the 2000s, several researchers have investigated women's demand for caesarean sections. Question The aim of this article was to review and summarise published studies investigating caesarean section demand and to describe the methodologies, outcomes, country characteristics and country income levels in these studies. Methods This is a systematic review of studies published between 2000 and 2017 in French and English that quantitatively measured women's demand for caesarean sections. We carried out a systematic search using the Medline database in PubMed. Findings The search strategy identified 390 studies, 41 of which met the final inclusion criteria, representing a total sample of 3 774 458 women. We identified two different study designs, i.e., cross-sectional studies and prospective cohort studies, that are commonly used to measure social demand for caesarean sections. Two different types of outcomes were reported, i.e., the preferences of pregnant or non-pregnant women regarding the method of childbirth in the future and caesarean delivery following maternal request. No study measured demand for caesarean section during the childbirth process. All included studies were conducted in middle-(n = 24) and high-income countries (n = 17), and no study performed in a low-income country was found. Discussion Measuring caesarean section demand is challenging, and the structural violence leading to demand for caesarean section during childbirth while in the labour ward remains invisible. In addition, the caesarean section demand in low-income countries remains unclear due to the lack of studies conducted in these countries. Conclusion We recommend conducting prospective cohort studies to describe the social construction of caesarean section demand. We also recommend conducting studies in low-income countries because demand for caesarean sections in these countries is rarely investigated.
