Explaining Vegetable Consumption among Young Adults: An Application of the Theory of Planned Behaviour.

Although fruit and vegetable consumption is highly recommended for a healthy and balanced daily diet, several European countries do not meet these recommendations. In Italy, only 45% of young people are consuming at least one portion of vegetables per day. Therefore, this paper aims to understand the main determinants of vegetables consumption among young adults to suggest possible intervention strategies. A cross-sectional study was conducted on a samples of Italian students (n = 751), using the theory of planned behaviour (TPB) as a conceptual framework. A structural equation model (SEM) was developed to test the TPB predictors for vegetable consumption, and the role of background factors (socio-demographic and personal characteristics) in improving the TPB model’s explaining power. Overall, 81% and 68%, respectively, of intentions and behaviour variance is explained by the TPB model. Socio-demographic and personal characteristics were found to influence intentions and behaviour indirectly by their effects on the theory’s more proximal determinants. Interventions should be targeted to improve perceived behavioural control (PBC), attitudes and subjective norms that significantly affect intentions. Tailored interventions for male students, enrolled in courses other than food science, and doing less physical activity may have a larger effect on behavioural change.

Consumer attitude towards sustainable-labelled wine: an exploratory approach.

Purpose – This paper aims to investigate, using an exploratory approach, how environmental values and beliefs about sustainable labelling shape consumer attitude towards sustainable wine. Design/methodology/approach – Data were collected with an online survey from 495 Italian wine drinkers in 2013. The survey was advertised through websites, blogs, social networks and emails. Based on background research and literature review, ten hypotheses were tested. Then a structural equation model was constructed using latent variables to test the causal links specified in the model. Findings – The results show that attitude towards sustainable-labelled wine is shaped by both environmental and quality beliefs about sustainable wine, while it is not affected by the economic dimension of sustainability. In addition, age appears to have a slight effect on attitude because young consumers seem to be more interested in sustainability aspects of food products than older people are. Practical implications – The paper sugge...

Factors driving sustainable choice: the case of wine

Purpose – The purpose of this paper is twofold: first, to explore the concept of consumers’ perception of sustainable wine and second, to investigate different clusters based on three factors identified (belief about environmental protection, beliefs about sustainable wine certification and attitude towards sustainable-labelled wine) and willingness to pay (WTP). Then, socio-demographic characteristics have been considered to assess whether group’s composition differ considerably. Design/methodology/approach – After preliminary literature review and qualitative analysis through focus groups, data were collected with a web-based questionnaire from 495 Italian wine drinkers. Factor analysis and cluster analysis were carried out using SPSS (21.0) statistical software packages. Findings – The cluster analysis based on the three factors identified confirms the presence of different segments of consumers. Four groups were identified and named: Well-disposed; Not interested; Skeptical; Adverse. Cluster analysis ...

A stakeholder engagement approach for identifying future research directions in the evaluation of current and emerging applications of GMOs

The yield of several commodity crops is provided in large part by genetically modified crops in North and South America. However, reservations exist in Europe due to possible negative effects on human health or environment. This paper aims to analyse the current research priorities identified in EU countries and to engage European stakeholders into the formulation of future common research needs regarding the effects of the possible adoption of commercially available and forthcoming genetically modified organisms (GMOs) in the areas of socio-economics, human and animal health, and environment. Additionally, it aims to identify the requirements for sharing available research capacities and existing infrastructures. First a mapping exercise of existing research activities in Europe was performed. A questionnaire was developed on a web-based platform and submitted to national focal points to collect information from EU Member States. Information was collected from 320 research projects conducted in the last 10 years in Europe. To refine results of the surveys, twenty invited experts and stakeholders from the public funding agencies of different EU Member States participated in an international workshop. This paper reports the main findings of these activities.
