Abstract (English)

Dietary habits are important precursors of childhood obesity. Youths’ dietary habits may be constrained by the experience of deprivation due to social (e.g., family purchasing power) and physical (e.g., availability of fast food outlets in low-income neighborhoods) factors limiting dietary choices. This study considers whether a Yitzhaki-based index of ego-centered relative neighborhood deprivation explains dietary outcomes (i.e., reported healthful and unhealthful food consumption), adjusting for absolute deprivation. The Yitzhaki index takes into account the total incomes to which a youth is deprived in relation to a meaningful reference group, and the youth’s position in the cumulative income distribution of this meaningful reference group. The study also considers whether the impact of deprivation on dietary outcomes is moderated by the experience of symptoms of depression. There was some indication that reported healthful food consumption was highest for youth who experienced low absolute deprivation (p-<=-0.01) and low symptoms of depression (p-<=-0.01), but high relative deprivation (p-<=-0.001). These youth therefore appear to benefit from being both "better-off", and living among "better-off" individuals. The results for reported unhealthful food consumption were less robust. The results may therefore suggest that youth who are not detrimentally impacted by their relative deprivation, and who have the financial means to access healthful foods, have improved dietary outcomes. The findings suggest that while absolute deprivation plays a key role in explaining healthful food consumption, additional insights can be gleaned from considering youths' relative deprivation and indicators of their well-being.
