The role of Optimistic Bias in safe food handling behaviours in the food service sector

This study evaluates the influences on food handlers' intention to conduct safe handling behaviours in food service settings in Brazil and the United Kingdom, focusing on Optimistic bias (OB). Although OB has been identified in food handlers in other studies, this is the first study evaluating the role of OB in determining behavioural intention. Three hundred participants, from the United Kingdom (n = 150) and Brazil (n = 150), completed a Theory of Planned Behaviour - based questionnaire, including additional questions about OB. For Brazilian food handlers, Attitude had a significant influence on Behavioural Intention followed by Subjective Norm, while Perceived Behavioural Control and OB did not significantly influence Behavioural Intention. For the United Kingdom, Perceived Behavioural Control had the largest influence, followed by Attitude, and then OB. Results suggest that cultural differences may influence predictors of behavioural intention, and that OB can contribute to predicting engagement in safe handling behaviours. Results contribute to a better understanding of the influences on food safety related behaviours.

Developing a Model of Organic Food Choice Behavior

We investigated the purchase intentions of consumers with respect to organic food and identified the determinants of the relationship between intended and realized purchase behavior. We conducted 2 surveys with South Korean consumers and developed a new organic food choice behavior model that reflects the relationship determinants. The factors affecting intention to purchase were evaluated using a survey based on the theory of planned behavior. Realized purchases were established through follow-up interviews with a subset (n = 20) of the participants who had completed the original survey. The key influences on intention to purchase were, in descending order, consumer past experience, attitude, the subjective norm, trust, and perceived behavioral control. The determinants of actual purchase behavior were unexpected circumstances, living circumstances, and price.

Food hygiene training in small to medium-sized care settings

Adoption of safe food handling practices is essential to effectively manage food safety. This study explores the impact of basic or foundation level food hygiene training on the attitudes and intentions of food handlers in care settings, using questionnaires based on the Theory of Planned Behaviour. Interviews were also conducted with food handlers and their managers to ascertain beliefs about the efficacy of, perceived barriers to, and relevance of food hygiene training. Most food handlers had undertaken formal food hygiene training; however, many who had not yet received training were preparing food, including high risk foods. Appropriate pre-training support and on-going supervision appeared to be lacking, thus limiting the effectiveness of training. Findings showed Subjective Norm to be the most significant influence on food handlers' intention to perform safe food handling practices, irrespective of training status, emphasising the role of important others in determining desirable behaviours.

Gap analysis of patient meal service perceptions

The provision of food and drinks to patients remains a largely unexplored, multidimensional phenomenon. In an attempt to ameliorate this lack of understanding, a survey utilising a modified SERVQUAL instrument measured on a seven-point Likert scale was carried out on-site at four NHS acute trusts for the purpose of assessing the perceptions and expectations of meal attributes and their importance in determining patient satisfaction. The results of factor analysis found three dimensions: food properties, interpersonal service, and environmental presentation, with a high reliability (Cronbach's alpha from 0.9191 to 0.7836). Path analysis further established sophisticated causal relations with patient satisfaction. The food dimension was found to be the best predictor of patient satisfaction among the three dimensions, while the interpersonal service dimension was not found to have any correlation with satisfaction. Bridging the gaps that exist between perceptions and expectations can improve the quality of meal services for the purpose of maximising patient satisfaction and ultimately aiding in patient recovery.

Food provision and the nutritional implications of food choices made by young adult males, in a young offenders' institution

The nutritional adequacy of diets provided by a prison was assessed by analysis of the kitchen menu for 1 week of a 4-week cycle. Dietary intakes were determined using a predefined 7-day diet diary in which prisoners indicated what they had eaten, and how much. A total of 159 prisoners took part in the study. The food provided by the prison kitchen was broadly in line with current dietary recommendations. Vitamin content exceeded recommendations, with the exception of niacin in the vegetarian menu (12.6 mg compared with the reference nutrient intake of 16.8 mg). Selenium content was low in all menus, but particularly in the vegetarian menu in 1997 where it equalled the lower reference nutrient intake (LRNI) (39.5 microg). Food choices made by prisoners resulted in a wide variation in dietary intakes. Fat intake (as a proportion of energy) exceeded the recommended 35% in 82% of diets in 1996, and 64% of diets in 1997. In 1996, 34% of prisoners had intakes above 40% energy as fat. High fat intakes were largely the result of consuming items from the prison shop. Vitamin D intakes were low (3.4 and 3.3 microg in 1996 and 1997, respectively) compared with the recommendation (10 microg) for those with limited exposure to sunlight. Intakes of a number of minerals fell below recommendations, with some prisoners barely meeting the LRNI. This was particularly notable for selenium where 35% of prisoners in 1996, and 60% of prisoners in 1997 had intakes below the LRNI.

Influence of supplementary vitamins, minerals and essential fatty acids on the antisocial behaviour of young adult prisoners. Randomised, placebo-controlled trial

BACKGROUND

There is evidence that offenders consume diets lacking in essential nutrients and this could adversely affect their behaviour.

AIMS

To test empirically if physiologically adequate intakes of vitamins, minerals and essential fatty acids cause a reduction in antisocial behaviour.

METHOD

Experimental, double-blind, placebo-controlled, randomised trial of nutritional supplements on 231 young adult prisoners, comparing disciplinary offences before and during supplementation.

RESULTS

Compared with placebos, those receiving the active capsules committed an average of 26.3% (95% CI 8.3-44.33%) fewer offences (P=0.03, two-tailed). Compared to baseline, the effect on those taking active supplements for a minimum of 2 weeks (n=172) was an average 35.1% (95% CI 16.3-53.9%) reduction of offences (P<0.001, two-tailed), whereas placebos remained within standard error.

CONCLUSIONS

Antisocial behaviour in prisons, including violence, are reduced by vitamins, minerals and essential fatty acids with similar implications for those eating poor diets in the community.

An analysis of catering options within NHS acute hospitals

Reforms of the NHS's healthcare structure have placed additional pressure on all aspects of hospital management. Evaluation of the effects of these reforms is difficult without more information on current conditions. Hospital catering in acute care trusts has little contemporary background research available. With this in mind, a survey of all the acute care NHS trusts within the eight regions in England was undertaken to investigate the hospital meal service process. A mailed questionnaire asked for the meal production system, food service method and food delivery personnel used by each trust, and a copy of a weekly menu. Results, from an 80.7 per cent response rate, indicate that most trusts use batch cooking to prepare their meals, and plated meal service to deliver the food to the wards. Almost 75 per cent of the trusts use nurses, at least in part, to serve food. English foodstuffs dominate the menus. Most of the trusts have moved towards meeting the goals set by the Patients' Charter and other NHS recommendations.
