Oysters represent an excellent source of major nutrients, especially proteins, vitamins and minerals. The consumption of oysters in Australia has not grown enough to match to their increased availability. This study is designed to provide information for the oyster industry to better attract more consumers to eat oysters. Six antecedent variables affecting the consumer choice of oysters: quality, safety, labelling, presentation, psychological aspects and preferred values for packaging and price, were identified by principal component factor analysis. A logistic regression approach predicts the consumer choice of oysters using these six factors and the demographic factors in the binary choice model. The outcome of the modelling predicts that the consumer choice of ‘dine in or out’ for oysters is significantly linked to age, gender, residence, labelling and preferred values, while the frequency of eating oysters annually is significantly influenced by the factors of age and preferred values. The oyster promotions such as nutritional marketing of oysters that have low cholesterol, cooking shows and special activities that target specific subsections of the consumer market are recommended in the study.

Oysters, one of the most popular shellfish, constitute an important food commodity in Australia. With the rapid growth of production, Australian oyster suppliers have realized the need for a better understanding of oyster consumption patterns to maximize economic returns. This study examines oyster consumer demographics and attitudes towards oysters, which in turn identify antecedent variables influencing consumer choice of oysters. Relevant antecedent variables such as quality, safety, labelling and preferred values were identified by factor analysis. A logistic regression analysis predicts consumer choice of oysters using those antecedent variables and the demographic factors. We recommend factors to be considered in the marketing of oysters.

To test the validity of using international standards as references for the assessment of nutritional status, investigations have been carried out on pre-school aged children selected from three distinct ecological environments in Papua New Guinea. Field work included anthropometric measurements (weight, height, triceps skin-fold, mid-upper-arm circumference, mid-upper-arm muscle circumference), together with pathological and clinical assessments (intestinal helminths, diarrhoea, splenomegaly, PEM signs). The findings indicate that any deviation below standard weight, height, and arm circumference is associated with greater prevalence of disease. International standards are therefore appropriate for preschool aged children in Papua New Guinea and by inference in other developing countries.
