Influence of Maternal Birth Status on Her Offspring: a Systematic Review and Meta-Analyses

Résumé
parity and LBW/PT/SGA.The study quality was assessed for biases in sample selection, exposure assessment, confounder adjustment, analyses, outcome assessment and attrition.Meta-analyses were performed using the random effect model.Unadjusted odds ratio (OR), weighted mean difference and 95% confidence intervals (CI) were calculated.The MOOSE statement criteria were followed.RESULTS: Forty studies were included.Most of them had moderate risk of bias due to failure to adjust for confounding factors.The results are presented in the table.Primiparity was associated with a reduction in birth weight (WMD 282g, 95% CI 79, 486g).CONCLUSIONS: Primiparity is associated with a significantly increased risk of LBW/SGA birth; however, the impact of confounding factors can not be underscored.BW was significantly lower in primipara mothers (an effect size similar to smoking in pregnancy).GM and GGM were not associated with LBW/PT.7 iNflueNce of MaterNal Birth status oN her offsPriNG: a systeMatic reVieW aNd Meta-aNalyses *Ps shah, V shah Knowledge synthesis Group, toronto, ontario BACKGROUND: Maternal low birth weight (LBW), preterm (PT) and/ or small for gestational age (SGA) status has been suggested as a precursor for infants being born LBW, PT or SGA.Exact mechanism by which intergenerational factors affect BW and GA are unknown; however, genetic modifiers and maternal environmental or constitutional factors are suspected to play a role.OBJECTIVE: To systematically review the risks for mothers who were LBW/ PT/SGA of having an infant being born LBW/PT/SGA.DESIGN/METHODS: Medline, Embase, CINAHL and bibliographies of identified articles were searched for English language studies of mother-infant pair being LBW, PT or SGA.Data were extracted by two authors independently and discrepancies were resolved by consensus.Study quality was assessed for biases in sample selection, exposure and outcome assessment, confounder adjustment, attrition, and analyses.When appropriate, the results were meta-analyzed and odds ratio (OR) and 95% confidence interval (CI) were calculated.MOOSE criteria were followed for meta-analyses.RESULTS: Twenty two studies from various sources (single center, regional or national databases) were included.The studies had low or moderate risk of bias.The results according to maternal LBW/preterm/SGA status for infants LBW/preterm/SGA status are reported in the Table.CONCLUSIONS: Maternal LBW/PT/SGA status was associated with an increased risk of LBW/PT/SGA status in the index child.Further research in the causation and prevention of this intergenerational association is needed.

Prédiction machine sur la base complète
Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
