Enablers and barriers to preconception dietary behaviours: a mixed method study with women of reproductive age.
Article in BMC women's health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundA healthy diet before conception (preconception) diet is associated with enhanced maternal health, improved cardiometabolic outcomes, reduced risk of pregnancy complications, and effective weight management. Yet, women of reproductive age frequently exhibit suboptimal dietary behaviours before conception. We aimed to examine the enablers and barriers associated with women's adherence to healthy preconception dietary behaviours.
methodsUsing sequential explanatory mixed methods, an online cross-sectional quantitative survey was followed by online qualitative interviews with women of reproductive age (18-45 years). Survey measures included the Healthy Eating Quiz (HEQ), and a pilot-tested new measure, the Preconception Diet Enablers and Barriers Scale (PDEBS) to evaluate barriers and enablers to diet. Linear regression analysed the relationship between Australian Recommended Food Score (ARFS) and barriers/enablers. Qualitative interviews were conducted to understand the reasons behind women's (non)engagement in healthy dietary habits. A weaving approach, use of joint-display, and the Capability Opportunity Motivation Behaviour (COM-B) model were used to integrate and present the data.
resultsSeven hundred and eighty-eight non-pregnant women (mean [M] age 32.08 years, SD = 7.31) residing in Australia, India, and the US completed the survey. Qualitative interviews (M duration = 30 min) were conducted with 13 women based in Australia. Women's capability to maintain a healthy preconception diet was influenced by their level of knowledge and awareness of its significance. Opportunities for a healthy preconception diet were shaped by social support, time availability, financial resources, and accessibility. Additionally, motivation to adhere to a healthful preconception diet was influenced by beliefs regarding its potential outcomes, alignment with personal goals, and emotional state.
conclusionOur findings advance understanding of the determinants influencing preconception dietary behaviours and provide valuable insights for designing effective interventions to promote healthy preconception dietary habits. By addressing the identified enablers and barriers comprehensively, policymakers, healthcare professionals, and researchers can work together to support women in adopting and maintaining healthy preconception dietary behaviours, ultimately improving maternal and child health outcomes.
