Subjective responses to meals are altered by shortened sleep time and anxiety state, but this effect has been poorly studied in shift workers – who act as a typical model concerning sleep restriction and present high levels of anxiety. The objective of this study was to compare subjective perceptions of meals and the levels of anxiety in the same subjects after working night shifts and after taking...
The burden of weight gain disproportionally affects young adults. Understanding the underlying behavioural mechanisms of change in mHealth nutrition and physical activity interventions designed for young adults is important for enhancing and translating effective interventions.First, we hypothesised that knowledge, self-efficacy and stage-of-change for nutrition and physical activity behaviours would...
Little is known about caregiver attitudes and perceptions towards snacking by toddlers and preschool children outside of the U.S. This qualitative study examined caregiver attitudes and perceptions towards the provision of both foods and beverages in-between meals, along with what constitutes a snack, or snacking occasion, amongst Swiss caregivers.This qualitative study used in-depth interviews (n = 17)...
Orthorexia nervosa is described as an exaggerated fixation on healthy food. It is unclear whether students in health-oriented academic programs, highly focused on physical exercise, are more prone to develop orthorexia nervosa than students in other educational areas. The aim was to compare health status, physical activity, and frequency of orthorexia nervosa between university students enrolled in...
A healthy diet plays a key role in preventing obesity and non-communicable diseases such as type 2 diabetes. This is true for all age groups, including young adults. While unhealthy eating habits among young adults, in particular university students, have been identified in former studies, this group has been neglected in existing health promotion strategies. Our aim was to explore baseline dietary...
By the time they reach retirement, individuals are typically highly experienced in sourcing food products and they have strong familiarity with food retailing environments. To investigate the ongoing role of food shopping in later life, the present study explored seniors' attitudes to food shopping and their food-selection behaviours through the lens of their broader lifestyles. The aim was to provide...
Current population-based methods for assessing dietary intake, including food frequency questionnaires, food diaries, and 24-h dietary recall, are limited in their ability to objectively measure food intake. Digital photography has been identified as a promising addition to these techniques but has rarely been assessed in self-serve settings. We utilized digital photography to examine university students'...
Reluctance to try novel foods (food neophobia) prevents toddlers from accepting healthy foods such as fish and vegetables, which are important for child development and health. Eating habits established between ages 2 and 3 years normally track into adulthood and are therefore highly influential; even so, there are few studies addressing food neophobia in this age group. This cross-sectional study...
There has been a decline in the consumption of potatoes in developed countries worldwide due to many factors including the introduction of new foods and meal trends. In turn, this shift in eating patterns has dramatically affected the Australian potato industry which represents the largest horticulture contributor to gross food revenue. Many factors may influence consumers' food preferences, including...
Parenting style influences a child's overall diet quality and establishes food preferences. Parenting style and “food rules” for children differ by eating at home or away from home. Eating meals away from home is increasing despite associations with consumption of unhealthy foods and higher weight status. The objective of the current study was to compare parenting practices and decision-making at...
The study of food choice, one of the most complex human traits, requires an integrated approach that takes into account environmental, socio-cultural and biological diversity. We recruited 183 volunteers from four geo-linguistic groups and highly diversified in terms of both genetic background and food habits from whom we collected genotypes and phenotypes tightly linked to taste perception. We confirmed...
Media exposure affects health, including obesity risk. Children's movies often contain food placements—frequently unhealthy foods. However, it is not known if these cues influence children's food choices or consumption after viewing. We explored whether children's snack choices or consumption differs based on: 1) recent exposure to movies with high versus low product placement of unhealthy foods;...
Social inequalities in diet are attributed to sociocultural determinants, economic constraints, and unequal access to healthy food. Fruits and vegetables are lacking in the diets of disadvantaged populations.The objective was to test the hypothesis that, in poor neighborhoods, community gardeners will have larger supply of healthy food, especially fruit and vegetables, than non-gardeners. We examined...
There is limited evidence on how diet changes over the transition from primary to secondary school. In this study we investigated changes in diet from age 10 (2007) to age 14 years (2011) and the contribution of school-time consumption and school lunch choice to such changes.The 351 participants with dietary data (4 day food record) available at baseline (age 10 years) and follow-up (age 14 years)...
This study aims to aid in the development of more effective healthy eating intervention strategies for pregnant women by understanding the relationship between healthy eating intention and actual eating behaviour. Specifically, the study explored whether Theory of Planned Behaviour (TPB) constructs [attitude, subjective-norm, perceived-behavioural-control (PBC)] and additional psychosocial variables...
Research investigating the effects of dietary behaviours on children's academic achievement has predominately focused on breakfast consumption. The aim of this study was to conduct secondary analysis to examine associations between a range of dietary behaviours and children's academic achievement.Data on five dietary variables (fruit intake; vegetable intake; consumption of takeaway; sugar sweetened...
Hispanic families are at elevated risk for certain diet related illnesses including obesity and diabetes. Brighter Bites is a 16-week school-based program that delivers produce and nutrition education to high-need areas. The purpose of this study was to explore the adoption of Brighter Bites healthy eating strategies in low-income Spanish-speaking families as well as barriers to the sustainability...
The term “food literacy” describes the idea of proficiency in food related skills and knowledge. This prevalent term is broadly applied, although its core elements vary from initiative to initiative. In light of its ubiquitous use—but varying definitions—this article establishes the scope of food literacy research by identifying all articles that define ‘food literacy’, analysing its key conceptualizations,...
Crunch&Sip is an Australian school-based initiative designed to increase the consumption of fruit, vegetables, and water among primary school children. To address the significant deficiencies in children's vegetable intake, the present study aimed to examine the responsiveness of parents (the main providers of food for Crunch&Sip) to a modified version of the program that focuses primarily...
This study examines trends in the prevalence of price promotions among packaged food and beverage purchases, differences in prevalence by household race/ethnicity or income, and the association between price promotions and the nutritional profile of purchases.This cross-sectional study utilizes a dataset of 90 million purchases from 38,744 (2008) to 45,042 (2012) US households in 2008–2012. Chi-square...
