Is there a relationship between product attributes, nutrition labels and excess weight? Evidence from an Italian region
No full textThis paper explores the association between Body Mass Index and a set of variables concerning consumer interest toward nutritional information, quality and marketing characteristics of food products. Socio-demographic and life-style aspects are also examined to profile excess weight consumers. The survey was conducted in a region of northern Italy, and the sample analysed is composed of 908 consumers. An Ordinal Regression Model was used in which the dependent variable is discrete and ordered and is expressed in terms of BMI ordinal categories. The analysis revealed that people with excess weight display a high level of interest in nutrition claims, namely, short and immediately recognised messages. Conversely, obese individuals assign less importance to marketing attributes (price, brand, and flavour) compared with normal weight consumers. Socio-demographic and life-style characteristics affect the rate of obesity, highlighting that the most vulnerable segments of population are more susceptible to excess weight problems

Economic factors affecting obesity : an application in Italy
No full textThe World Health Organisation has stated that obesity is spreading around the world like a “global epidemic”. In 2004 the percentage of obese people in the Italian population was 9%, but the trend is increasing in recent years. Focussing on this country, the purpose of the paper is to analyse the socio-economic variables affecting obesity by means of a survey conducted in a consumer sample.
Our analysis is based on a survey conducted in Italy, and the sample was composed of 999 consumers. We used a binary logit model and the dependent variable is body mass index (BMI), expressed in a dichotomic way (seriously overweight and obese, value 1, and normal weight, value 0). The results show that the condition of the seriously overweight and obese increases with age, especially in people over 65 of age. Also gender is correlated with the pathology: being seriously overweight and obese is far more likely for men than for women. An inverse relation was shown between obesity and education, and between obesity and the level of food knowledge. The results highlight that disadvantaged social categories are more susceptible to the problem of overweight and obesity. A policy implication of the analysis, to limit the spread of obesity, could lie in programs aimed at improving health and food awareness and focused on these minority groups
Time spent for food information search and obesity : North-South dualism in Italy
No full textIn industrialized countries, the last 40 years has seen a marked change in the average level of per capita calorie intake, which has led to increased growth in overweight and obesity rates. There are many reasons to encourage public intervention aimed at facing the problems associated with excess body weight, and to promote healthy dietary habits. Among the public policies set out to reduce obesity rates, an important role is played by information measures. The purpose of this work is to analyse for the consumers the importance of food information in the allocation of free time, and to investigate the variables that affect the search for information. Following Drichoutis et al. (2008) we developed a conceptual framework through variables that affect the time spent searching for information. The study was conducted through an empirical analysis, and the sample consisted of 300 Italian consumers, 150 resident in Lombardy (northern Italy), and 150 in Apulia (southern Italy). The interviews were conducted in small shops, supermarkets and hypermarkets. For small shops we selected greengrocers, butcher's shops and shops selling dairy products. The data were analysed through OLS regression and ordinal regression models. The study, for the south sample, showed a relationship between the consumer willingness to devote time to information search and work flexibility, information stock, nutritional knowledge. In the case of northern sample, another variable that affects the time allocated for information search is BM

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
