Food Consumed

The aim of this study is to characterize the relationship between food consumption and socio-demographic characteristics in several groups of individuals. This is achieved by capturing the quantity of food purchased in categories on a microeconomic level. The empirical analysis is approached through the estimation of (a) expanded generalized linear models, (b) quantile regression models, (c) quadratic almost ideal demand system models and (d) Deaton’s (1988) approach. The results reveal that the composition of a household has a significant impact on the quantity of food consumed. In addition, price and income elasticities are estimated, confirming that the majority of food items are inelastic with respect to price and income except for meat. These findings can be used as a basis for considering food policy implications while evaluating the potential gains from applying specific policies.

The study aims to describe trends in food consumption away from home in Brazil from 2002-2003 to 2008-2009 and to analyze the influence of income on this behavior. The authors used data collected by the Household Budget Surveys conducted by the Brazilian Institute of Geography and Statistics (IBGE) in 2002-2003 and 2008-2009. The information analyzed in this study involves records of food and beverage purchases for consumption away from home. Trends in eating away from home were estimated for the total population and according to demographic and economic strata. The association between the share of food consumed away from home and income was studied using regression models to estimate income elasticity coefficients. The share of eating away from home increased 25% during the period, reaching 28% of total spending on food. Each 10% increase in mean per capita income leads to a 3.5% increase in the share of food consumed away from home. This suggests that income growth will result in future increases in the share of eating away from home.

ObjectiveHelicobacter pyloriinfection is a major cause of several cancers such as gastric, pancreatic and lung. The relationship betweenH. pyloriand tumour markers continues to remain unclear. The primary goal of this study is to clarify the associations betweenH. pyloriinfection and six tumour markers (ie, carcinoembryonic antigen (CEA), cancer antigen (CA) 153, CA199, CA724, CA125 and alpha-fetoprotein (AFP)). The secondary goal is to provide understanding for further research aboutH. pyloriinfection and gastrointestinal cancer.DesignObservational retrospective study.SettingThe study was performed in Beijing, China, where enrolled subjects had all passed health examinations during the period of 2012–2016. Subjects were categorised intoH. pylori(+) andH. pylori(–) group according to their infection status and the measured six biomarkers. We used logistic regression models and generalised linear models to explore the associations betweenH. pyloriinfection and six tumour markers (ie, CEA, CA153, CA199, CA724, CA125 and AFP).ParticipantsA total of 14 689 subjects were included and 6493 (44.2%) subjects were infected byH. pylori. The subjects had a mean age (1SD) of 45 (18) years. There were 4530 (31.0%) female subjects.ResultsAfter adjusting for the confounding factors, infections withH. pyloriwere found to be significantly associated with abnormal ratios in CEA, AFP and CA724 ofH. pylori(+) toH. pylori(–) groups. Significant positive correlation was found betweenH. pyloriinfection and CEA values (adjusted β=0.056; 95% CI 0.005 to 0.107; p=0.033).ConclusionsIn this observational retrospective study, we observed theH. pyloriinfections in a Chinese population and found higher CEA level inH. pylori-infected subjects and abnormal ratios in CEA, AFP and CA724 in infected subjects to uninfected subjects. These findings may provide a basis for future exploration withH. pyloriand tumour markers.

The nutrition transition in China has proceeded to the extent that the food -consumption behaviour of low-income and high-income groups is different. Failure to consider these differences could lead to inappropriate assumptions about some basic food policy issues. This analysis was undertaken using a sample of adults 1850 years old from the 1991 China Health and Nutrition Survey. Low-income families have a greater propensity to increase or decrease fat and calorie intakes than high-income families. This difference has important, policy implications and shows why it should be considered in making decisions regarding consumption behaviour. Selecting the appropriate income switching or cut-off point is central to capturing this structural difference.

AbstractThis paper conducts a meta-analysis of price and income elasticities for wine and distilled spirits, which correct for outliers and publication bias. The sample of wine elasticities is obtained from 104 primary studies, and the sample of spirits elasticities is obtained from 111 primary studies. Robust weighted-means and meta-regressions are reported that correct for outliers, heterogeneity, heteroskedasticity, dependence, and publication bias. Compared to unweighted averages previously reported in the literature, the analysis yields less-elastic demands for both price and income. Average price elasticities obtained using cumulative meta-analysis are −0.45 for wine and −0.55 for spirits. Average income elasticities are 1.0 for both beverages. Bias due to publication selectivity is important. Country-level differences also are noted for both wine and spirits. Policy implications are discussed for pricing and taxation of alcohol beverages.

Economists pay considerable attention to the influential factors on the economic growth in the framework of the growth models. In the same direction, the relationship between inflation and economic growth in Iran has been investigated during 1978-2008. First, an adjusted model has been designed based on (Barro) model and then the relationship between inflation and economic growth has been estimated using both ARDL and rolling linear regression models. The results derived from the both estimated models showed that the effect of inflation on economic growth is negative and Significance.

Using a sample of 3,041 incarcerated men and women, this study examines the impact of being incarcerated for a sex offense and individuals’ in-prison experiences on their concerns about reentry into society. Bivariate analyses suggest that being incarcerated for a sex offense is related to greater concerns about housing and fewer concerns about recidivism compared with individuals incarcerated for nonsex offenses. A sex offense conviction is also associated with weaker social bonds, greater relational difficulties, and greater fear of victimization while incarcerated. Multiple regression models indicate that, after controlling for in-prison experiences, being incarcerated for a sex offense increases reentry concerns related to employment and housing, though may reduce them for recidivism. In-prison experiences mediate the relationship between being incarcerated for a sex offense and reentry concerns. Policy implications of these findings are discussed.

Transitioning agri-food systems towards increased sustainability and resilience requires that attention be paid to sustainable food consumption policies. Policy-making processes often require the engagement and acceptance of key stakeholders. This study analyses stakeholders’ solutions for creating sustainable agri-food systems, through interviews with a broad range of stakeholders including food value chain actors, non-governmental organizations, governmental institutions, research institutions and academic experts. The study draws on 38 in-depth, semi-structured interviews conducted in four European countries: France, Iceland, Italy and the UK, as well as three interviews with high-level EU experts. The interviewees’ solutions were analysed according to a five-category typology of policy tools, encompassing direct activity regulations, and market-based, knowledge-based, governance and strategic policy tools. Most of the identified solutions were located in the strategic tools category, reflecting shared recognition of the need to integrate food policy to achieve long-term goals. Emerging solutions—those which were most commonly identified among the different national contexts—were then used to derive empirically-grounded and more universally applicable recommendations for the advancement of sustainable food consumption policies.
