Second Stage Labour Duration and Pelvic Floor Outcomes in Primiparous Women, 200 Subjects

A prospective study of 200 primiparous women delivering macrosomic foetuses, stratified by second-stage labour duration and assessed at six weeks postpartum. The dataset includes ultrasound measurements of pelvic floor structures, pelvic floor muscle strength and function assessments, and records of stress urinary incontinence and pelvic organ prolapse incidence. The data was published by Jiaxi Jin on figshare under a CC-BY-4.0 license.

Use Cases

• Analyze the association between prolonged second-stage labour and pelvic organ prolapse incidence based on recorded POP occurrences.
• Model the relationship between labour duration and pelvic floor muscle strength based on Oxford scale and vaginal pressure test results.
• Investigate the correlation between pushing time and levator ani hiatus dimensions based on transperineal ultrasound measurements.
• Train classifiers to predict postpartum pelvic floor dysfunction risk based on labour duration and infant macrosomia status.

Strengths

• Dataset includes detailed clinical measurements from 200 subjects, providing a substantial sample size for analysis.
• Contains multiple, specific outcome measures: pelvic floor muscle strength (Oxford scale), vaginal pressure (class I/II fibres), levator hiatus area, and incidence rates of SUI and POP.
• Data is stratified into three clear comparison groups based on second-stage labour duration (Group A: ≥3h, Group B: 2-3h, Group C: <2h).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect temporal or demographic bias inherent to a single prospective study.
