Planting seeds of change: reconceptualizing what people eat as eating practices and patterns

Lifestyle Medicine in Medical Education: Maximizing Impact

The relationship between lifestyle behaviors and common chronic conditions is well established. Lifestyle medicine (LM) interventions to modify health behaviors can dramatically improve the health of individuals and populations. There is an urgent need to meaningfully integrate LM into medical curricula horizontally across the medical domains and vertically in each year of school and training. Including LM content in medical and health professional curricula and training programs has been challenging. Barriers to LM integration include lack of awareness and prioritization of LM, limited time in the curricula, and too few LM-trained faculty to teach and role model the practice of LM. This limits the ability of health care professionals to provide effective LM and precludes the wide-reaching benefits of LM from being fully realized. Early innovators developed novel tools and resources aligned with current evidence for introducing LM into didactic and experiential learning. This review aimed to examine the educational efforts in each LM pillar for undergraduate and graduate medical education. A PubMed-based literature review was undertaken using the following search terms: lifestyle medicine, education, medical school, residency, and healthcare professionals. We map the LM competencies to the core competency domains of the Accreditation Council for Graduate Medical Education. We highlight opportunities to train faculty, residents, and students. Moreover, we identify available evidence-based resources. This article serves as a "call to action" to incorporate LM across the spectrum of medical education curricula and training.

Ultra-processed food consumption in UK adolescents: distribution, trends, and sociodemographic correlates using the National Diet and Nutrition Survey 2008/09 to 2018/19

PURPOSE

We quantified levels of ultra-processed food (UPF) consumption and investigated consumption patterns in a representative sample of UK adolescents.

METHODS

We used data from 4-day food diaries from adolescents in the UK National Diet and Nutrition Survey (NDNS) (2008/09-2018/19). UPF were identified using the NOVA classification. We estimated the percentage of Total Energy Intake (%TEI) and the absolute weight (grams). Linear regression models quantified differences in UPF consumption across survey years and its association with participant's individual characteristics. This was an analysis of the repeated cross-sectional data from the UK NDNS Rolling Programme waves 1-11 (2008/09-2018/19). A total of 2991 adolescents (11-18y) with complete information on dietary intake were included.

RESULTS

Mean UPF consumption was 861 (SD 442) g/d and this accounted for 65.9% (SD 13.4%) of TEI. Between 2008 and 2019, mean UPF consumption decreased from 996 to 776 g/d [ - 211 (95%CI  - 302;  - 120)] and from 67.7% to 62.8% of TEI [ - 4.8% (95%CI  - 8.1;  - 1.5)]. Higher %TEI was consumed by adolescents with lower socioeconomic status; white ethnicity and living in England North. A higher weight of UPF consumption (g/d) was associated with being male, white, age 18y, having parents with routine or manual occupation, living in England North, and living with obesity.

CONCLUSION

Average energy intake from UPF has decreased over a decade in UK adolescents. We observed a social and regional patterning of UPF consumption, with higher consumption among adolescents from lower socioeconomic backgrounds, from a white ethnicity and living in England North. Our findings suggest inequalities associated with UPF intake and factors that might lie beyond individual choice.

Children's descriptions of their involvement within everyday food practices

BACKGROUND

The way in which children interact with food has a profound impact on their health and wellbeing. However, most research, strategy and policy where food is the focus are derived from adult perspectives. There is limited understanding of children's perspectives of the nature of their everyday food practices, and their level of involvement and influence. This work garnered children's (8-12 years old) descriptions of, and involvement in, their everyday food practices.

METHODS

Forty-two children from 28 families from across Brisbane (Australia) participated in qualitative creative draw-and-tell interviews and 20 of these children (from 15 families) also completed Photovoice data collection. Data were abductively analysed through a social practice theory lens.

RESULTS

Children reported engaging in food planning, acquisition, preparation, consumption and tidy-up practices, to varying degrees of 'less involved', 'in partnership with adults or other children' or 'independently'. This was influenced largely by the willingness of adults to relinquish control and children's desire to participate, as well as other contextual factors. Children were more independent in consumption practices, as well as packing lunchboxes and preparing food spaces (as preparation practices). Partnerships were established more so within food acquisition and preparation practices, with less involvement described within planning and tidy-up practices.

CONCLUSIONS

The findings add new knowledge and depth and breadth to that already obtained from parents, teachers and adult researchers, highlighting the importance of privileging children's voices when investigating their food experiences. This work may be used to guide adults to invite and support children to be involved in food practices that they report being less involved in, as well as inform how best to work with and include children in future research and food and nutrition strategies and policies.

Primary-school-aged children inspire their peers and families to eat more vegetables in the KiiDSAY project: a qualitative descriptive study

BACKGROUND

While vegetable intakes in Australia remain sub-optimal across all age groups, children are rarely consulted about their ideas on how to increase consumption. Qualitative research involving children provides an opportunity to consider their views. The aim of the Kids initiative inspires Dietary Success in Adults and Youth (KiiDSAY) project was to explore the views of school-aged children, who had participated in a school-based nutrition education program, about inspiring their peers and families to eat more vegetables.

METHODS

A total of 26 children (15 boys) aged 10-12 years from four primary schools in New South Wales, Australia, participated in seven focus group interviews. Purposeful sampling was used to recruit participants. The study involved open-ended semi-structured questions conducted via Zoom that were audio-recorded, transcribed verbatim and analysed using thematic analysis with deductive and inductive coding in NVivo.

RESULTS

Four major themes emerged: (i) taste; (ii) family environment; (iii) healthy eating; and (iv) change makers; with subthemes that were embedded within Social Cognitive Theory and Ecological Model of Health Behaviour theoretical frameworks.

CONCLUSIONS

Children's inputs hold great potential for informing future interventions, particularly when designing or refining school-based nutrition programs. Children offered suggestions on how to inspire increased vegetable consumption among their peers and families that could be taken into consideration for future research and practice. These included: cooking activities in the home and school settings using recipes that creatively hide/mask/enhance the flavour of vegetables, involving positive role models and supportive school environments. Additionally, children recommended a sequential approach to the delivery of recipes starting from fruit-based and transitioning to vegetable-based recipes. Given the challenges faced in increasing children's vegetable consumption, particular focus on future research in this area is warranted.

Do 20-minute neighbourhoods moderate associations between work and commute hours with food consumption?

OBJECTIVE

To examine associations between work and commute hours with food consumption and test whether neighbourhood type (20-minute neighbourhood (20MN)/non-20MN) moderate associations.

DESIGN

Cross-sectional analysis of the Places and Locations for Activity and Nutrition study (ProjectPLAN). Exposures were work hours (not working (0 h), working up to full-time (1-38 h/week), working overtime (> 38 h/week)), and among those employed, combined weekly work and commute hours (continuous). Outcomes were usual consumption of fruit, vegetables, takeaway food, snacks and soft drinks, and number of discretionary food types (takeaway, snacks and soft drinks) consumed weekly. Generalised linear models were fitted to examine associations between each exposure and outcome. The moderating role of neighbourhood type was examined through interaction terms between each exposure and neighbourhood type (20MN/non-20MN).

SETTING

Melbourne and Adelaide, Australia, 2018-2019.

PARTICIPANTS

Adults ≥ 18 years old (n 769).

RESULTS

Although all confidence intervals contained the null, overall, patterns suggested non-workers and overtime workers have less healthy food behaviours than up-to-full-time workers. Among those employed, analysis of continuous work and commute hours data suggested longer work and commute hours were positively associated with takeaway consumption (OR = 1·014, 95 % CI 0·999, 1·030, P-value = 0·066). Patterns of better behaviours were observed across most outcomes for those in 20MN than non-20MN. However, differences in associations between work and commute hours with food consumption across neighbourhood type were negligible.

CONCLUSIONS

Longer work and commute hours may induce poorer food behaviours. There was weak evidence to suggest 20MN moderate associations between work and commute hours with food consumption, although behaviours appeared healthier for those in 20MN.

Understanding the role of the state in dietary public health policymaking: a critical scoping review

Despite evidence that dietary population health interventions are effective and widely accepted, they remain the topic of intense debate centring on the appropriate role of the state. This review sought to identify how the role of the state in intervening in individuals' food practices is conceptualized across a wide range of literatures. We searched 10 databases and 4 journals for texts that debated dietary population health interventions designed to affect individuals' health-affecting food practices. Two co-authors independently screened these texts for eligibility relative to inclusion and exclusion criteria. Thirty-five texts formed our final corpus. Through critical reflexive thematic analysis (TA), we generated 6 themes and 2 subthemes concerning choice, responsibility for health, balancing benefits and burdens of intervention, the use of evidence, fairness, and the legitimacy of the state's actions. Our analysis found that narratives that aim to prevent effective regulation are entrenched in academic literatures. Discourses that emphasized liberty and personal responsibility framed poor health as the result of 'lifestyle choices'. Utilitarian, cost-benefit rationales pervaded arguments about how to best balance the benefits and burdens of state intervention. Claims about fairness and freedom were used to evoke powerful common meanings, and evidence was used politically to bolster interests, particularly those of the food industry. This review identifies and critically analyses key arguments for and against population dietary public health policies. Our findings should motivate public health researchers and practitioners to avoid unreflexively embracing framings that draw on the languages and logics of free market economics.

Integrating coordination of food purchasing into activity space-based food environment research: Toward a household perspective

Despite the advances in person-based approaches to studying food environments, most studies using these approaches have relied on individual-centered activity space measures and largely ignored cohabiting household members who play crucial roles in shaping an individual's food access, food behaviors, and diet. This can be problematic for completely capturing food environments relevant to an individual and add uncertainties to explorations of how individuals' food environments relate to their food behaviors. This viewpoint discusses the need for, and implications of, considering household members when measuring food access and disentangling the behavioral pathways connecting the food environment to diet. Ultimately, a conceptual framework and potential questions are proposed to integrate household members into food environment research.

Do food-related capabilities, opportunities and motivations of adolescents mediate the association between socioeconomic position in adolescence and diet quality in early adulthood?

BACKGROUND

Socio-economic position (SEP) in adolescence may influence diet quality over the life course. However, knowledge of whether individual and environmental determinants of diet quality mediate the longitudinal association between SEP and diet quality is limited. This study examined whether and to what extent food-related capabilities, opportunities and motivations of adolescents mediated the longitudinal association between SEP in adolescence and diet quality in early adulthood overall and by sex.

METHODS

Longitudinal data (annual surveys) from 774 adolescents (16.9 years at baseline; 76% female) from ProjectADAPT (T1 (baseline), T2, T3) were used. SEP in adolescence (T1) was operationalized as highest level of parental education and area-level disadvantage (based on postcode). The Capabilities, Opportunities and Motivations for Behaviour (COM-B) model was used as a framework to inform the analysis. Determinants in adolescence (T2) included food-related activities and skills (Capability), home availability of fruit and vegetables (Opportunity) and self-efficacy (Motivation). Diet quality in early adulthood (T3) was calculated using a modified version of the Australian Dietary Guidelines Index based on brief dietary questions on intake of foods from eight food groups. Structural equation modelling was used to estimate the mediating effects of adolescents' COM-B in associations between adolescent SEP and diet quality in early adulthood overall and by sex. Standardized beta coefficients (β) and robust 95% confidence intervals (CI) were generated, adjusted for confounders (T1 age, sex, diet quality, whether still at school, and living at home) and clustering by school.

RESULTS

There was evidence of an indirect effect of area-level disadvantage on diet quality via Opportunity (β: 0.021; 95% CI: 0.003 to 0.038), but limited evidence for parental education (β: 0.018; 95% CI: -0.003 to 0.039). Opportunity mediated 60.9% of the association between area-level disadvantage and diet quality. There was no evidence of an indirect effect via Capability or Motivation for either area-level disadvantage or parental education, or in males and females separately.

CONCLUSIONS

Using the COM-B model, the home availability of fruit and vegetables (Opportunity) of adolescents explained a large proportion of the association between area-level disadvantage in adolescence and diet quality in early adulthood. Interventions to address poor diet quality among adolescents with a lower SEP should prioritize environmental determinants of diet quality.

Nutrition and behavior change: a review of recent literature

PURPOSE OF REVIEW

The current article will highlight recent trends and novel approaches to behavior change strategies in nutrition. Physicians, nurses, and other healthcare professionals play key roles in counseling patients on lifestyle change, which is critical for patients with chronic conditions. Nutrition science continues to advance, and new approaches to behavior change are needed for successful implementation at the individual and population level.

RECENT FINDINGS

The solutions to obstacles around healthful eating patterns are varied, population-dependent, and require a multipronged approach. One area of focus is the language around behavior change, ensuring it is clear and emphasizes its multifactorial nature. For young adults, the careful use of video games and social media may be essential. For older adults, altering food consistency and ensuring proper nutrient intake are crucial factors. Vulnerable populations remain susceptible to malnutrition and need special attention. Despite significant advances in managing and treating diseases, there are still gaps in nutrition counseling and behavior change efforts.

SUMMARY

Every age and stage of life needs a focus on healthful foods, and nutrition counseling at each stage has its unique nuances. Careful attention to the language of change and the phrasing used in counseling is vital for educating, connecting with, and empowering patients to change. Changing healthcare operations and provider behavior around nutrition counseling is a part of the solution to the worldwide problem of unhealthy eating patterns and practices.

Validity of a Market Basket Assessment Tool for Use in Supplemental Nutrition Assistance Program Education Healthy Retail Initiatives

OBJECTIVE

To assess the validity of the Market Basket Analysis Tool (MBAT) for food environment quality within various retail environments compared to the Nutrition Environment Measures Survey in Stores (NEMS-S).

METHODS

In-store assessments using the MBAT and the NEMS-S on the same day in a given store were conducted in grocery stores, corner stores, pharmacies, and dollar stores in a metropolis, and urban and rural counties across 4 states: Louisiana, Mississippi, North Carolina, and Virginia. Descriptive statistics, correlations, and ANOVAs were used to assess store location, store type differences, and MBAT and NEMS-S scores.

RESULTS

Market Basket Analysis Tool and NEMS-S data were collected from 114 stores. Market Basket Analysis Tool and NEMS-S total and all individual component scores were significantly correlated (r = 0.84, P ≤ 0.0001; r range, 0.51-0.88; P ≤ 0.0001).

CONCLUSIONS AND IMPLICATIONS

The MBAT offers a methodology to measure the food retail environment focusing on the availability of healthful food items with a reduced training time and streamlined data collection compared with the NEMS-S. Future work can assess the completion time of the MBAT compared with the NEMS-S and the ability of the MBAT to detect changes in food environment quality post healthy food retail interventions.

A need for multi-sector and multi-pronged solutions to address the many barriers inhibiting change from unhealthy food environments in publicly funded recreation facilities: a mixed-method study

Public recreation facilities are preferred gathering places for families to participate in physical, social, intellectual, and creative pursuits, and the importance of food environments in these facilities is gaining recognition. Evidence from other Canadian jurisdictions describes such food environments as unsupportive of health, which contradicts national recreation priorities to have healthy choices as the easy choices. This study aimed to characterize food environments in a convenient sample of Saskatchewan public recreation facilities. A convergent/parallel mixed methods study design used quantitative methods to determine the healthfulness of concession stands and vending machines and qualitative methods to examine barriers and facilitators to healthy eating at facilitates. Results found that 5% of concession main dishes were defined as healthy and packaged foods/beverages in concession stands and vending machines were defined as Offer Most Often 6% and 8% of the time, respectively, according to Saskatchewan Nutrition Standards. Reported barriers to healthy eating were more than twice as prevalent as facilitators. To align with population health recommendations in Saskatchewan, food environments in public recreation facilities require immediate attention. Results and recommendations can be used to build collective action to address the problem and as a benchmark to measure change. Novelty Bullets • Only 5% of concession main dishes were defined as healthy. • Only 6% of packaged foods and beverages in concessions, and 8% in vending, were defined as Offer Most Often. • Reported barriers to healthy eating were more than twice as prevalent as facilitators, resulting in a current state that is difficult to change.

Influence of work hours and commute time on food practices: a longitudinal analysis of the Household, Income and Labour Dynamics in Australia Survey

OBJECTIVES

Work hours and commute time are key contributors to time scarcity, with potential detrimental implications for healthy eating. This study examined (1) associations between work and commute hours with food practices and (2) within-individual associations between changes in work and commute hours with changes in food practices.

DESIGN

Longitudinal study SETTING: Australia PARTICIPANTS: Data were from 14 807 respondents in waves 7 (2007), 9 (2009), 13 (2013) and 17 (2017) of the Household, Income and Labour Dynamics in Australia Survey. The sample for this analysis included individuals who were in paid employment in at least one of the four waves.

PRIMARY AND SECONDARY OUTCOME MEASURES

Outcomes included frequency of out-of-home food purchasing for breakfast, lunch, dinner and all three summed eating occasions, and fruit and vegetables consumption.

RESULTS

Results indicated the longer individuals spent working and commuting, the more likely they were to purchase out-of-home foods (frequency of total out-of-home food purchasing: incidence rate ratio (IRR)=1.007 (95% CI 1.007 to 1.008)), and the less they consumed fruit and vegetables, although reductions in fruit and vegetables servings were minimal (fruit: β=-0.002 (95% CI -0.003 to -0.001), vegetables: β=-0.002 (95% CI -0.003 to -0.001)). Similar results regarding associations with out-of-home food purchasing were observed when examining within-individual changes (IRR=1.006 (95% CI 1.005 to 1.007)).

CONCLUSIONS

Results suggest employment-related time demands push towards more frequent out-of-home food purchasing. In the long term, this may have negative health consequences as out-of-home foods tend to be less healthy than home-prepared foods.

Where do Dutch adults obtain their snack foods? Cross-sectional exploration of individuals' interactions with the food environment

We investigated frequency of consumption and location of obtaining snack foods and sociodemographic differences therein. Data: cross-sectional survey data (N = 1784 Dutch adults 18-65 years) on the frequency of consumption of 10 snack foods and where they obtained them. Adjusted logistic regression analyses revealed notable differences in the frequency of snack food consumption between younger and older adults and between those with low vs. high socioeconomic position (SEP). The location of obtaining snack foods also differed between sociodemographic groups with supermarkets forming an important point-of-purchase for snack foods, especially for those with low SEP and with children in their household.

A systematic review of trucking food, physical activity, and tobacco environments and tractor-trailer drivers’ related patterns and practices in the United States and Canada, 1993–2021

•

The built environment is recognized to influence health patterns and practices.

•

No review has explored trucking food, physical activity, and tobacco environments.

•

Trucking built environment science is underdeveloped and requires validated tools.

•

Future research should explore truckers’ views on built environment interventions.

•

More emphasis on the trucking built environment and health equity is warranted.

Truckers in the United States (U.S.) and Canada are at high risk for noncommunicable disease. Although trucking built environments have been highlighted for intervention, no systematic review has assessed aspects of trucking environments that may influence food, physical activity (PA), and smoking patterns/practices. The purpose of this systematic review was to characterize the state of the science on trucking food, PA, and tobacco environments and to examine truckers’ food, PA, and tobacco patterns/practices. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were used. Five databases were selected for searching in April 2020 and 2021 using key terms constructed by a librarian. Peer-reviewed research with data about U.S. and Canadian truckers’ (i.e., drivers operating 18-wheelers or tractor trailers) food, PA, and/or tobacco environments and related patterns/practices were included. Quality was assessed using the Mixed Method Appraisal Tool. Thirty-eight studies were identified. Results included data from at least 16,600 truckers and 282 trucking settings in the U.S. (n = 32) and Canada (n = 6). Most studies were classified as quantitative descriptive and of poor quality (average score 3 of 7). The few studies (n = 4) that measured trucking food and PA environments characterized trucking sites as poor. Fifteen (47%) presented data about truckers’ perceptions of food or PA environments and highlighted prominent environmental barriers. Truckers’ food, PA, and smoking patterns and practices suggested poor diet quality, sedentary practices, and a high prevalence of smoking. The science of trucking food, PA, and tobacco environments is underdeveloped and requires much more focus using validated measures.
