A search in Medline and Embase identified 51 articles reporting association of spontaneous abortion (SA), preterm delivery (PTD) or small-for-gestational-age (SGA) infant with exposure to occupational lifting. A global validity score was assigned to each study and six potential sources of bias were considered in sensitivity analyses. For each exposure\u2013outcome combination, a summary risk estimate (RE) was obtained from all studies and from a subset of studies with high validity score, this latter summary RE was selected as a final result. Statistical heterogeneity was measured with I\n                    <jats:sup>2<\/jats:sup>\n                    and Q tests and the possibility of a publication bias was also assessed. For each meta-analysis, the strength of evidence was established from explicit criteria. Heavy (or \u226510\u2009kg) loads often (or \u226510x\/day) lifted were associated with increased risks of SA (summary RE=1.31, 95% CI 1.17 to 1.47) and PTD (summary RE=1.24, 95%\u2009CI 1.07 to 1.43), with good strength of evidence. No association was identified with SGA, nor with lower exposure levels and SA or PTD. These results are reassuring for lower levels of exposure; however, observed associations can guide health professionals\u2019 recommendations aimed at the prevention of SA and PTD for pregnant women who frequently lift (or \u226510x\/day) heavy (or \u226510\u2009kg) loads at work.\n                  <\/jats:p>\n                  <jats:p>R\u00e9sum\u00e9<\/jats:p>","DOI":"10.1136\/oemed-2019-106334","type":"journal-article","created":{"date-parts":[[2020,3,17]],"date-time":"2020-03-17T17:19:38Z","timestamp":1584465578000},"page":"496-505","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":35,"title":["Occupational lifting and adverse pregnancy outcome: a systematic review and meta-analysis"],"prefix":"10.1136","volume":"77","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8279-2835","authenticated-orcid":false,"given":"Agathe","family":"Croteau","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2020,3,17]]},"reference":[{"key":"2024110804401995000_77.7.496.1","unstructured":"Statistique Canada (SC), Enqu\u00eate sur la population active, 2018, adapt\u00e9 par l\u2019Institut de la statistique du Qu\u00e9bec (ISQ) .
