The objective of this study was to determine the impact of two nudge interventions on customers’ produce purchases at a rural Canadian grocery store. A pre- and post-intervention observational study design was used. Sales data were gathered before and after the staggered implementation of two nudge-based interventions to encourage produce purchases: grocery cart dividers to encourage shoppers to fill one-third of their cart with produce and grocery cart plaques with information about how many fruits and vegetables were typically purchased in the store. The proportion of total sales accounted for by produce was compared between baseline and implementation of the first intervention (Phase 1), between implementation of the first intervention and the addition of the second intervention (Phase 2), and between baseline and post-implementation of both interventions together. There was a 5% relative increase (0.5% absolute increase) in produce spending between baseline and post-implementation of both interventions (10.3% to 10.8%, p < 0.001, 95% CI 0.2%, 0.7%). Intervention phase-specific produce spending showed no significant change in the percentage of produce spending from baseline to Phase 1 of the intervention, and an 8% relative increase (0.8% absolute increase) in the percentage of produce spending from Phase 1 to Phase 2 of the intervention (10.3% to 11.1%, p < 0.001, 95% CI 0.5, 1.1%). Simple, low-cost nudge interventions were effective at increasing the proportion of total grocery spend on produce. This study also demonstrated that partnerships with local businesses can promote healthier food choices in rural communities in Canada.
Background Despite being a well-accepted part of paediatric care, little is known about the benefits or potential harms of routine growth monitoring (RGM) from a parent’s perspective. Objective To explore parental experiences with RGM. Methods Literature searches were performed on Google Scholar, psycINFO, CINAHL, and PubMed. Included studies were published after 2000 and described parental comprehension, preferences, attitudes toward, and/or behaviour change related to RGM. Results Of 24 reviewed studies, four themes were identified: reliance on growth monitoring, understanding, influence on feeding and behaviour, and response to obesity-related classification. RGM was familiar but not strongly preferred to identify a child’s weight status. Parental understanding of RGM was poor, particularly among parents with low socioeconomic status. A common belief was that heavier babies were healthier, while smaller babies should prompt concern. Parents may be anxious and change behaviour in response to RGM, such as by halting breastfeeding, supplementing, or restricting their child’s diet. Parents frequently discounted RGM information when their child was identified as overweight, and expressed concerns about self-esteem and eating disorders. Conclusion This scoping review identifies that although RGM is familiar and sometimes reassuring to parents, increased consideration should be given to potential harms from parental perspectives when conducting growth monitoring.
Background: Infancy appears to be a critical period for establishing a person's weight set point. It remains unclear which interventions during infancy may be most effective in preventing later obesity and which ones are most acceptable to parents. The aim of this study was to examine the attitudes of parents of children aged 2 years and under toward different obesity prevention messages and their preferences with regard to these messages. Methods: Using a qualitative research design, we conducted semistructured interviews followed by a focus group. Parents of children under 2 years of age were purposively recruited from 2 communities in British Columbia, Canada, and asked for their opinions about various health promotion messages relating to obesity prevention. A theoretical thematic analysis was used to analyze the data. Results: Thirty-three parents participated in the study. Participants reported that many of the current recommendations (no screen time, no sugary beverages) are unrealistic, unclear and inconsistent, making them difficult to follow and causing parents to feel guilty; they had a more positive response to the feeding roles message. Parents noted the importance of starting education early and targeting the broader community. Interpretation: Several important and interesting themes were identified in this study, which increases our understanding of parents' attitudes toward and preferences for the messages presented. Obesity prevention information for today's busy parents needs to be realistic, supportive and timely.
