Aims: To evaluate the effectiveness of web‐based mobile health interventions on paediatric patients and their parents in the day surgery context, where the primary outcome was children's pre‐operative anxiety and secondary outcomes were postoperative pain and parents’ anxiety and satisfaction with entire course of the day surgery.Design: A systematic review and meta‐analysis of randomized controlled trials.Data Sources: CENTRAL, CINAHL, Scopus, Ovid MEDLINE, and Web of Science were systematically searched without time limits (up to December 2018).Review Methods: Studies were appraised using the Cochrane risk of bias tool. A random effect meta‐analysis of children's pre‐operative anxiety was performed.Results: Eight studies with a total of 722 patients were included in the analysis. The effectiveness of web‐based mobile health interventions, including age‐appropriate videos, web‐based game apps, and educational preparation games made for the hospital environment, was examined in pre‐operative settings. A meta‐analysis (N = 560 children) based on six studies found a statistically significant reduction in pre‐operative anxiety measured by the Modified Yale Pre‐operative Anxiety Scale with a moderate effect size. Three studies reported parental satisfaction.Conclusion: Web‐based mobile health interventions can reduce children's pre‐operative anxiety and increase parental satisfaction. Web‐based mobile health interventions could be considered as non‐pharmacological distraction tools for children in nursing. There is not enough evidence regarding the effectiveness of reducing children's postoperative pain and parental anxiety using similar interventions.Impact: Web‐based mobile health interventions reduce children´s pre‐operative anxiety and could therefore be considered as non‐pharmacological distraction tools for children in nursing.

Breastfeeding attitudes are known to influence infant feeding but little information exists on the prenatal breastfeeding attitudes of parents. The purpose of this study was to describe Finnish parents' prenatal breastfeeding attitudes and their relationships with demographic characteristics.
