AbstractObjectiveTo find diets optimised on nutrition and environmental impact close to the current Dutch diet and to identify the most effective and acceptable options for mitigating environmental impact.DesignLinear programming was used to optimise diets of Dutch men and women aged 9–69 years, divided into ten age–gender groups. The analysis included nutrient composition, a metric for popularity and life cycle assessments of 207 food products. Greenhouse gas emissions, fossil energy use and land occupation were used to calculate a weighted score for the overall environmental impact. Optimised diets were solutions that minimised changes to the current diet while satisfying all nutritional constraints, with stepwise reductions in environmental impact.SettingThe Netherlands.SubjectsDutch children and adults aged 9–69 years.ResultsMeat was always reduced. Vegetable, fruit and dairy contents remained similar, while bread, fatty fish and legumes increased. The extent of changes depended on age and gender. Beverages were not heavily reduced. Nutrients critical for the outcome were α-linoleic acid, retinol, Ca, Na, Se, dietary fibre, SFA, thiamin and Fe (women of childbearing age). Total protein, essential amino acids and carbohydrates were not critical.ConclusionsReducing meat is the most effective option for lowering the environmental impact of diets in all age–gender groups. Reducing alcoholic and non-alcoholic beverages is another option. Leaving out fish and dairy products are not. The differences in nutritional requirements related to age and gender have a significant effect on the composition of the optimised diets.

This chapter describes how American bloggers and Chinese bloggers from similar age and gender groups represent themselves and their identities linguistically in their blogs and explores whether and to what extent the differences in terms of the blogging language and culture affect these representations. The author adopts a corpus-based approach and focuses on the description and the comparison of the orthographic features and semantic domain preference as revealed in the blog entries. By conducting a cross-linguistic and cross-cultural comparison between American bloggers and Chinese bloggers, the author finds that bloggers’ linguistic practice is closely related to their developmental stage of life, their gender, and the cultural environment they are immersed in. Meanwhile, bloggers’ linguistic practice is also constrained by the internal system of the language they use for blogging.

The purpose of this chapter is to analyze the physical aerobic work in terms of the metabolic expenditure and compare it with the recommended boundaries of energy found in literature, proposing an alternative to the potential work overload through a compensatory equation introduced in the standard time of the workstation. To support the study, information considering the estimated metabolic expenditure in workers was applied to a novel procedure to reduce the metabolic demand of the task according to age and gender. Results of the study indicated that women older than 30 years exceeded the energy limits from moderate to very heavy load activities, and men older than 40 years exceeded the energy limits in heavy and very heavy workloads. The proposal of compensatory equation statistically reduced the energy loads below the recommended limits of energy. The aerobic workload is a sensitive factor for age and gender groups and can be potential risks for developing cardiovascular diseases as well as some musculoskeletal disorders.

Purpose The purpose of this paper is to analyse consumer buying behaviour in the Japanese rice wine, also known as sake market. Design/methodology/approach The study applies a novel qualitative and quantitative analytical methodology to an off-license channel in Japan. The methodology involves the use of anchoring-and-adjustment theory and simulation to a large set of point of sale data. The selection of the brands used for the study are more than 230 brands and more than 150 sake breweries. Findings Age and gender are important factors determining recurrent patterns of purchasing behaviour. Small size packaging, e.g. one cup, has the highest volume in sales, for example, convenience shopping, but it depends on exogenous factors, e.g. summer season or festive events. Research limitations/implications Limitations are related with the lack of specific personal data from consumers that impedes to test behavioural attitudes driving loyalty to brands. Anchoring-and-adjustment theory can be a valid approach to evaluate large longitudinal data sets of purchasing behaviour. Practical implications Results indicate that fragmented markets tend to over-expand the assortment affecting volume stability. However, this dynamics is difficult to avoid when all participants are engaged in this behaviour and the market is strongly segmented by age and gender. Originality/value The paper contributes to the body of knowledge of buyer behaviour in relation to purchasing and consumption for other types of wine. It is the first application in alcoholic beverages of anchor-and-adjustment theory.

The present study examined the effect of warning labels in alcohol advertising on the perception of risk for alcohol consumption. Under incidental conditions, subjects from two age groups, young (M = 13.6 years) and older (M = 23.3 years), examined a collection of magazine ads. Three of the ads in the booklet were for alcoholic beverages and these were either accompanied by a warning or the warning was absent. When present, the warnings were manipulated by the orthogonal combination of text voice (2nd vs. 3rd person) and pictorial (presence vs. absence) in a between-subjects design. A fifth condition served as the no-warning control. After examining the magazine ads, subjects answered a questionnaire which assessed several dimensions related to the ads: number and type of ads, attractiveness of the ads, and number and type of warnings in the ads. Examination of the questions dealing with the risk of alcohol consumption indicated that adolescents rated their own risk lower than the risk to adolescents in general, but that this bias in risk ratings was not evident when warnings were present. There were also several other age and gender effects. While no individual warning manipulation was found to be consistently superior to another, the results suggest that warnings can be effective in producing proper estimations of risk in different age populations.

AbstractObjectiveTo assess the relative validity and repeatability of a sixty-four-item FFQ for estimating dietary intake of Zn and its absorption modifiers in Saudi adults. In addition, we used the FFQ to investigate the effect of age and gender on these intakes.DesignTo assess validity, all participants completed the FFQ (FFQ1) and a 3 d food record. After 1 month, the FFQ was administered for a second time (FFQ2) to assess repeatability.SettingJeddah, Saudi Arabia.SubjectsOne hundred males and females aged 20–30 years and 60–70 years participated.ResultsMean intakes of Zn and protein from FFQ1 were significantly higher than those from the food record while there were no detectable differences between tools for measurement of phytic acid intake. Estimated intakes of Zn, protein and phytate by both approaches were strongly correlated (P<0·001). Bland–Altman analysis showed for protein that the difference in intake as measured by the two methods was similar across the range of intakes while for Zn and phytic acid, the difference increased with increasing mean intake. Zn and protein intakes from FFQ1 and FFQ2 were highly correlated (r>0·68,P<0·001) but were significantly lower at the second measurement (FFQ2). Older adults consumed less Zn and protein compared with young adults. Intakes of all dietary components were lower in females than in males.ConclusionsThe FFQ developed and tested in the current study demonstrated reasonable relative validity and high repeatability and was capable of detecting differences in intakes between age and gender groups.
