Does gym use impact upon nutritional knowledge?

Purpose – The purpose of this paper is to investigate gym and non-gym users' use and understanding of nutrition labels. Design/methodology/approach – A consumer survey in the form of a questionnaire conducted in the Greater London area in February/March 2005. Subject recruitment process took place in both a gym and university setting. Frequency tables and ?2-test are used to assess relationships between variables (p=0.05). Findings – The resulting sample consisted of 187 subjects, with predominance of females and gym users. Of the subjects, 88 per cent reported to at least occasionally read nutrition labels, with higher reading rates amongst women, irrespective of gym user status. Total and saturated fats are the most often information viewed on labels, however the overall knowledge of the calorie content of fat is low, with 53 per cent of subjects responding saturated fat contains more calories per gram when compared with other types of fats. This paper does not find significant differences in the use and understanding of nutrition labels between gym and non-gym users, but highlights the publics' continued lack of understanding of nutrition labels. Originality/value – This paper is unique as it investigates whether there is any difference between gym/non-gym users' use and interpretation of use of nutrition labels. It finds gender impacted more on nutritional labels knowledge than gym user's status. This points to a gender issue and questions the quality of information available to the general public. This paper is valuable as it highlights and identifies an area that requires further research and assessment, and is therefore useful to key stakeholders responsible for public health nutrition.

The road not taken: observing a process of issue selection and model conceptualization

This article describes a case study involving information technology managers and their new programmer recruitment policy, but the primary interest is methodological. The processes of issue generation and selection and model conceptualization are described. Early use of “magnetic hexagons” allowed the generation of a range of issues, most of which would not have emerged if system dynamics elicitation techniques had been employed. With the selection of a specific issue, flow diagraming was used to conceptualize a model, computer implementation and scenario generation following naturally. Observations are made on the processes of system dynamics modeling, particularly on the need to employ general techniques of knowledge elicitation in the early stages of interventions. It is proposed that flexible approaches should be used to generate, select, and study the issues, since these reduce any biasing of the elicitation toward system dynamics problems and also allow the participants to take up the most appropriate problem- structuring approach.
