Poverty and obesity: the role of energy density and energy costs

Does social class predict diet quality

Objective To examine the self-reported importance of taste, nutrition, cost, convenience, and weight control on personal dietary choices and whether these factors vary across demographic groups, are associated with lifestyle choices related to health (termed health lifestyle), and actually predict eating behavior. Design Data are based on responses to 2 self-administered cross-sectional surveys. The main outcomes measured were consumption of fruits and vegetables, fast foods, cheese, and breakfast cereals, which were determined on the basis of responses to questions about usual and recent consumption and a food diary. Subjects/setting Respondents were a national sample of 2,967 adults. Response rates were 71% to the first survey and 77% to the second survey (which was sent to people who completed the first survey). Statistical analyses Univariate analyses were used to describe importance ratings, bivariate analyses (correlations and t tests) were used to examine demographic and lifestyle differences on importance measures, and multivariate analyses (general linear models) were used to predict lifestyle cluster membership and food consumption. Results Respondents reported that taste is the most important influence on their food choices, followed by cost. Demographic and health lifestyle differences were evident across all 5 importance measures. The importance of nutrition and the importance of weight control were predicted best by subject's membership in a particular health lifestyle cluster. When eating behaviors were examined, demographic measures and membership in a health lifestyle cluster predicted consumption of fruits and vegetables, fast foods, cheese, and breakfast cereal. The importance placed on taste, nutrition, cost, convenience, and weight control also predicted types of foods consumed. Applications Our results suggest that nutritional concerns, per se, are of less relevance to most people than taste and cost. One implication is that nutrition education programs should attempt to design and promote nutritious diets as being tasty and inexpensive. J Am Diet Assoc. 1998;98:1118-1126 .

Obesity and the food environment: dietary energy density and diet costs.

Context: It is well established in the literature that healthier diets cost more than unhealthy diets. Objective: The aim of this review was to examine the contribution of food prices and diet cost to socioeconomic inequalities in diet quality. Data Sources: A systematic literature search of the PubMed, Google Scholar, and Web of Science databases was performed. Study Selection: Publications linking food prices, dietary quality, and socioeconomic status were selected. Data Extraction: Where possible, review conclusions were illustrated using a French national database of commonly consumed foods and their mean retail prices. Data Synthesis: Foods of lower nutritional value and lower-quality diets generally cost less per calorie and tended to be selected by groups of lower socioeconomic status. A number of nutrient-dense foods were available at low cost but were not always palatable or culturally acceptable to the low-income consumer. Acceptable healthier diets were uniformly associated with higher costs. Food budgets in poverty were insufficient to ensure optimum diets. Conclusions: Socioeconomic disparities in diet quality may be explained by the higher cost of healthy diets. Identifying food patterns that are nutrient rich, affordable, and appealing should be a priority to fight social inequalities in nutrition and health.

Contribution of food prices and diet cost to socioeconomic disparities in diet quality and health: a systematic review and analysis.

OBJECTIVE: The purpose of this baseline survey was to obtain comparable data on perceived influences on food choice from EU member countries as the starting point for EU healthy eating promotion campaigns and programmes.DESIGN: A cross-sectional study in which quota-controlled, nationally-representative samples of approximately 1000 adults from each country completed a face-to-face interview-assisted questionnaire.SETTING: The survey was conducted between October 1995 and February 1996 in the 15 member states of the European Union.SUBJECTS: 14331 subjects (aged 15 y upwards) completed the questionnaire. Data were weighted by population size for each country and by sex, age and regional distribution within each member state.RESULTS: The five most important factors influencing consumers food choice were 'quality or freshness' (74%), 'price' (43%), 'taste' (38%), 'trying to eat healthy' (32%) and 'family preferences' (29%). Subjects in different categories (age, sex, education and employment status) selected different factors as having major influence on their food choice. Demographic factors seemed to have greater effects on perceived influences than culture (country): 'quality/freshness', 'price', 'trying to eat healthy', 'family preferences' seemed to be most important in women, 'taste' and 'habit' in males. Females and older and more educated subjects were more likely than other subjects to select 'trying to eat healthy' as having a major influence. 'Price' seemed most important in unemployed and retired subjects.
