  • SummaryAlthough considerable research is being conducted with a view to improve outcomes for pregnant women with obesity and their babies, much of this research is compromised by the quality of outcome reporting. Our aim is to determine how outcomes have been reported and measured in obesity in pregnancy studies, as a first step towards developing a core outcome set to standardize outcome reporting in future trials. We conducted a systematic review of clinical trials and systematic reviews on obesity in pregnancy in accordance with the Preferred Reporting in Systematic Reviews and Meta‐analyses guidelines. We searched Medline, Embase, controlled register of trials, World Health Organization International Clinical Trials Registry, and Google Scholar, for relevant studies and extracted study characteristics, outcome reporting and measurement. Reporting quality was assessed using previously published criteria. Outcomes were grouped using a published taxonomy and variations in outcome reporting and measurement were descriptively presented. Seventy included studies yielded a total of 135 outcomes. Foetal/neonatal outcomes were not reported in 53.3% of studies where an intervention could have implications to both, mother and baby. Reported outcomes were mostly physiological/clinical (74.8%), with very limited representation of outcomes related to mortality/survival (5.2%), life impact (7.4%), adverse events (5.9%) and resource utilization (6.7%).
