Stable isotopes (carbon, nitrogen, sulfur), diet, and anthropometry in urban Colombian women: Investigating socioeconomic differences

Abstract

Stable isotope values revealed a difference between SES groups that was not explained by the dietary data. The relationship between diet and stable isotope composition is complex.

Economic and demographic predictors of dietary variation and nutritional indicators in Nicaragua

“…As predicted, household wealth is a significant predictor of both δ 13 C and δ 15 N. That is, the models indicate that wealthier households eat diets that are relatively enriched in terms of carbon and nitrogen. These data are consistent with another isotopic study examining socioeconomic differences in diet in Colombia (Bender et al, ), which found that women with higher SES had more enriched δ 13 C and δ 15 N than women of lower SES. As opposed to calculating wealth from household possessions, the Bender et al study relies on categorizing wealth via the average income in the participants' neighborhoods.…”

“…Analysis of carbon and nitrogen isotopic ratios is a powerful tool for quantitatively examining diets and dietary variation within populations. In modern populations, isotopic ratios have been used to show dietary differences between sexes (Umezaki et al, ), among ages (Wilkinson, Yai, & O'brien, ), and across individuals of different socioeconomic status (SES) (Bender et al, ). We contributed to this literature through examination of isotopic heterogeneity within a single Nicaraguan population while showing that isotopic variation related both to household‐level resources and individual‐level demographic attributes.…”

“…In modern societies, nutritionists have shown differences in diet and nutrition across demographic groups, including between sexes (Christiaensen & Alderman, ; Hadley, Lindstrom, Tessema, & Belachew, ), among age groups (Lamontagne, Engle, & Zeitlin, ; Winking & Koster, ), among socioeconomic classes (Barros, Victora, Scherpbier, & Gwatkin, ), or among families with differing levels of education (Christiaensen & Alderman, ; Sakisaka et al, ). Isotopic analysis has been used to support some of these findings, particularly differences between sexes (Umezaki et al, ) and classes (Bender et al, ).…”

Evaluation of childhood nutrition by dietary survey and stable isotope analyses of hair and breath

“…Previous studies have shown that the stable isotopes of hair can be used to distinguish among Europeans with omnivorous, ovo‐lacto‐vegetarian, or vegan diets (Bol & Pflieger, ; Petzke, Boeing, Klaus, et al, ; Petzke, Boeing, & Metges, ; Petzke et al, ). However, these biomarkers have rarely been applied in large populations (Bender et al, ; Gragnani, Garavello, Silva, Nardoto, & Martinelli, ; Kusaka et al, ; Thompson et al, ; Valenzuela, Chesson, Bowen, Cerling, & Ehleringer, ; Valenzuela et al, ) or in the context of nutritional epidemiology (Bender et al, ; O'Brien, ; Petzke et al, ). While isotopic analysis of hair provides a time‐integrated dietary signal, isotopic analysis of breath CO 2 provides a measure of recent carbohydrate metabolism (O'Brien, ).…”
