Funded PhD Opportunity

Investigating the key drivers of food portion size among children; challenges and opportunities in an obesogenic environment .

Subject: Biomedical Sciences


Summary

The predisposition to overeat in response to large portion sizes (PS) appears to be a ubiquitous phenomenon and occurs irrespective of age.  Several observational and experimental studies show that from as early as 1 year, children eat greater amounts when presented with larger food portions (1-2), even though at this young age, food intake is reported to occur primarily in response to hunger and satiety cues (3). There is a general paucity of research into the key drivers that influence portion control in children. The supervisory team have shown that parents of children aged 3y and under may not consider the impact of larger than appropriate food PS on weight status in their children, or appreciate the potential influence of early portion control on future eating behaviour (4).

The proposed PhD will investigate this aspect further, and gain parental opinions in regard to food PS representative of a broader age range of children. The ‘Eatwell Guide’ (5), provides recommendations about the types and proportions of each key food group to consume daily. However, with the exception of the fruit and vegetable food group, there are no PS recommendations available in the UK guidance. Various PS guides from non-governmental organisations (NGOs) and the food industry exist; however, these tend to communicate inconsistent and sometimes conflicting advice, which facilitates confusion among consumers (6).

Recent safefood funded research conducted by the supervisory team has identified a strong consumer preference and acceptance of ‘visual’ portion size estimation aids to estimate appropriate PS (7). Understanding the practical implications of the use of simple and visual portion size tools may facilitate the control of energy intake. The proposed PhD will add to this growing evidence base by including an examination of the implications of using practical portion size tools in the home setting (e.g a 200 ml disposable cup).

The main objectives of the proposed PhD research will be met using a range of research methods to: (a)systematically review and evaluate the literature and other relevant sources of information to determine the impact and influencers of typical food PS reported among children and adolescents (b)examine typical PS patterns of commonly consumed foods in a representative cohort of both Irish and UK children using national survey data (c)evaluate (both qualitatively and quantitatively) a suitable 200-ml prototype reusable cup, alongside other portion control aids (such as plates/teaspoons) to assist adults and children in managing portion control in the home setting on the Island of Ireland.

This work will form part of a safefood supported project recently awarded to the supervisory team (‘Portion control tools; do they work in practice?’ Ref: 01-2018) (d)investigate parental knowledge, attitudes and behaviour regarding food portion sizes for children from aged 3-12 years (this aspect will extend the previous data collected in parents of children aged<3y (4))

The PhD researcher appointed to the project will be given every opportunity to maximize personal and professional development by participating in relevant workshops, specialist skills sessions, relevant online courses, PhD researcher initiatives and personal development activities organised by the Doctoral College. In addition, the PhD researcher will be expected and strongly encouraged to prepare and present their research findings when appropriate at national and international conferences of relevance e.g. those organised by the Nutrition Society and the Association for Obesity.
