This research focuses on a more fundamental reason for this relationship: psychological consequences of the experience of scarcity resulting from a low income. Hence, there may be other explanations for why having a low income contributes to unhealthy eating.
Dijkstra et al., 2018 Lee, Kane, Ramsey, Good, & Dick, 2016). However, research focused on the role of food prices and perceived affordability of healthy foods in diet quality of different income groups has shown inconsistent findings (e.g. A dominant explanation is that a low income induces a selection of less expensive unhealthy, high energy‐dense foods. Moreover, lower incomes are associated with higher obesity rates (Schoenborn, Adams, & Barnes, 2002) in both developed and developing countries (James, Leach, Kalamara, & Shayeghi, 2001).
It has been well established that diet quality differs over income groups: people with low income have more unhealthy diets (Drewnowski & Specter, 2004 Ricciuto & Tarasuk, 2007). Trade‐off task (scarcity manipulation) as used in Study 3 and 4, presented is the “no‐scarcity extra” condition, translated from Dutch to Englishĭiet‐related diseases such as obesity, diabetes, and heart disease are approaching epidemic levels in many parts of the world (Deitel, 2003 Fardet & Boirie, 2014 Wagner & Brath, 2012). Trade‐off task (scarcity manipulation) as used in Study 2, presented is the scarcity condition, translated from Dutch to English Trade‐off task (scarcity manipulation) as used in Study 1, presented is the scarcity condition, translated from Dutch to English Results of t‐tests comparing the two conditions on scarcity related states in Study 4 Means, SDs, and Correlations of the Variables under Study in Study 4 ( N = 122) Post hoc results (Dunnett's tests) comparing both no‐scarcity conditions with the scarcity condition on scarcity related states in Study 3 Results of t‐tests comparing the two conditions on scarcity related states in Study 2 Means, SDs, and Correlations of the Variables under Study in Study 2 (N = 95) Results of t‐tests comparing the two conditions on scarcity related states in Study 1 Study 1– Measurements of states related to scarcity
