Little empirical research exists about what motivates birth mode preferences, and even less about this topic in Latin America, where obstetric interventions and caesareans are some of the highest worldwide.
To identify factors associated with caesarean preference among Chilean men and women who plan to have children and to inform childbirth education and informed consent procedures.
An online cross-sectional survey measuring attitudes toward birth was administered to graduate students at a large public university in Chile. Eligible students were under the age of 40 and had no children but intended to have children. Logistic regression modelling was used to determine which sociodemographic factors, knowledge and beliefs were associated with caesarean preference.
Among eligible students, 730 responded and 664 provided complete answers to the variables of interest. Respondents had a mean age of 28.8; 38% were male and 62% female. Positive attitude toward technological intervention (Odds Ratio 7.4, 95% Confidence Interval 3.9-14.0), high risk perception of vaginal birth (Odds Ratio 1.8, 95% Confidence Interval 1.1-2.8), family history of caesarean (Odds Ratio 1.9, 95% Confidence Interval 1.0-3.8) and high fear of birth (Odds Ratio 3.7, 95% Confidence Interval 2.0-6.8) were associated with caesarean preference.
Preference for caesarean birth was highly associated with positive attitudes toward technological intervention and may be related to a lack of knowledge about the realities of caesarean and vaginal birth.
Patient-centered education on the relative benefits and risks of birth modes has the potential to influence preferences toward vaginal birth.
关于促使人们偏好某种分娩方式的因素，实证研究较少，而在全球剖宫产率最高的拉美地区，这方面的研究就更少了。
确定智利计划生育的男性和女性选择剖宫产的相关因素，并为分娩教育和知情同意程序提供信息。
对智利一所大型公立大学的研究生进行了一项关于分娩态度的在线横断面调查。符合条件的学生年龄在 40 岁以下，没有孩子，但计划要孩子。使用逻辑回归模型确定社会人口因素、知识和信念与剖宫产偏好的关联。
在符合条件的学生中，有 730 人回应，664 人完整回答了感兴趣的变量。受访者的平均年龄为 28.8 岁；38%为男性，62%为女性。对技术干预持积极态度（优势比 7.4，95%置信区间 3.9-14.0）、对阴道分娩风险感知高（优势比 1.8，95%置信区间 1.1-2.8）、有剖宫产家族史（优势比 1.9，95%置信区间 1.0-3.8）和对分娩的高度恐惧（优势比 3.7，95%置信区间 2.0-6.8）与剖宫产偏好相关。
对剖宫产的偏好与对技术干预的积极态度高度相关，这可能与对剖宫产和阴道分娩的实际情况缺乏了解有关。
以患者为中心的关于分娩方式相对益处和风险的教育有可能影响对阴道分娩的偏好。
