Abstract: Abstract Objectives Assessments of health-related quality of life outcomes associated with preterm birth provide valuable complementary data to the objective biomedical assessments that have traditionally been reported. The objective of this study was to perform a systematic review and meta-analysis of health utility values associated with preterm birth generated using preference-based approaches to health-related quality of life measurement. Methods Systematic searches of MEDLINE, Web of Science, EconLit, EMBASE, CINAHL, PsycINFO, the Cochrane Library and SCOPUS were performed, covering the literature from inception of the search engines to 26 June 2018. Studies reporting health utility values estimated using either direct or indirect utility elicitation methods and published in the English language were included. Central descriptive statistics and measures of variability surrounding health utility values for each study and control group, and differences between comparator groups, are reported for each included article. The effect of preterm birth on health utility values was estimated using a hierarchical linear model in a linear mixed-effects meta-regression. Results Of 2139 unique articles retrieved, 20 articles met the inclusion criteria. All but one study used the Health Utilities Index (HUI) Mark 2 (HUI2) or Mark 3 (HUI3) measures as their primary health utility assessment method. All studies reporting health utility values for individuals born preterm or at low birthweight and a control group of individuals born at full term or normal birthweight reported lower utility values in the study groups, regardless of age at assessment, respondent type or valuation method. The meta-regression revealed that preterm birth was associated with a mean utility decrement of 0.066 (95% confidence interval [CI] 0.035–0.098; p
