ObjectivesWe aimed to identify the core elements of centredness in healthcare literature. Our overall research question is: How has centredness been represented within the health literature published between 1990 and 2019?MethodsA scoping review across five databases (Medline (Ovid), PsycINFO, CINAHL, Embase (Ovid) and Scopus; August 2019) to identify all peer-reviewed literature published since 1990 that focused on the concept of centredness in any healthcare discipline or setting. Screening occurred in duplicate by a multidisciplinary, multinational team. The team met regularly to iteratively develop and refine a coding template that was used in analysis and discuss the interpretations of centredness reported in the literature.ResultsA total of 23 006 title and abstracts, and 499 full-text articles were screened. A total of 159 articles were included in the review. Most articles were from the USA, and nursing was the disciplinary perspective most represented. We identified nine elements of centredness: Sharing power; Sharing responsibility; Therapeutic relationship/bond/alliance; Patient as a person; Biopsychosocial; Provider as a person; Co-ordinated care; Access; Continuity of care. There was little variation in the concept of centredness no matter the preceding word (eg, patient-/person-/client-), healthcare setting or disciplinary lens. Improving health outcomes was the most common justification for pursuing centredness as a concept, and respect was the predominant driving value of the research efforts. The patient perspective was rarely included in the papers (15% of papers).ConclusionsCentredness is consistently conceptualised, regardless of the preceding word, disciplinary lens or nation of origin. Further research should focus on centring the patient perspective and prioritise research that considers more diverse cultural perspectives.

Introduction: Healthy preconception and antenatal diet and physical activity behaviors may optimize maternal and offspring outcomes. These behaviors are thought to be linked to pregnancy intentions. The aim of this study was to conduct a systematic review and meta-analysis to determine the association between women's pregnancy intentions and diet or physical activity behaviors in the preconception and antenatal periods. Methods: MEDLINE Complete, PsycINFO, CINAHL Complete, Global Health, Embase, and INFORMIT: Health Subset were searched in September 2018 for studies that evaluated relationships between pregnancy intentions and dietary and physical activity behaviors. Risk of bias was assessed, and random effects meta-analyses were conducted for dietary (food groups; energy and macronutrients; diet quality; and caffeine, iodine, and folate intake) and physical activity outcomes. Results: Of 2623 screened records, 19 eligible studies were identified. The overall risk of bias was moderate to high. Twelve studies measured diet and physical activity behaviors during preconception, 5 during pregnancy, and 2 across both periods. Eleven studies measured pregnancy intention retrospectively, and 8 prospectively measured pregnancy intention. The number of studies available for meta-analyses of individual dietary and physical activity outcomes ranged from 2 to 5. Pregnancy intentions were not associated with preconception fruit, vegetable, or caffeine intake or physical activity. Antenatally, women with intended pregnancies were more likely to report healthier diets, lower caffeine intake, and higher physical activity. Insufficient studies were available to conduct subgroup comparisons for prospective or retrospective assessment. Discussion: Pregnancy intentions were not associated with preconception diet or physical activity behaviors. In contrast, antenatally, women with intended pregnancies demonstrated better diet and physical activity behaviors. Given the small number of studies available for meta-analyses, further research is needed to consolidate our findings. Meanwhile, health professionals can assess women's pregnancy intentions during preconception and pregnancy and encourage a healthy lifestyle.

Background: Postpartum weight retention is a significant contributor to obesity in women, adverse perinatal events in subsequent pregnancies, and chronic disease risk. Health literacy is known to impact health behaviors. The study aimed to identify the health literacy domains utilized in postpartum weight management interventions and to determine their impact on weight, diet and physical activity in postpartum women. Methods: We searched MEDLINE, CINAHL, EMBASE, PSYCINFO, and EBM databases. We included random control trials of lifestyle intervention in postpartum women (within two years post-delivery) published up to 3 May 2019. Subgroup analyses were performed to determine the effect of health literacy domains on outcomes. Results: Out of 5000 studies, 33 studies (n = 3905) were included in the systematic review and meta-analysis. The health literacy domain self-care (skills and knowledge) was associated with a significant reduction in body weight (mean difference (MD) −2.46 kg; 95% confidence interval (CI) from −3.65 to −1.27) and increase in physical activity (standardized mean difference (SMD) 0.61; 95% CI 0.20 to 1.02). No other health literacy domain was associated with significant outcomes in weight, energy intake, or physical activity. Conclusions: Health literacy skills such as knowledge of self-care are effective in improving weight and in increasing physical activity in postpartum women. The efficacy of other health domains was not supported.
