Abstract
Natural abundances of stable nitrogen and carbon isotopes (delta N-15 and delta C-13) can vary with both dietary intake and metabolic (specifically catabolic) state. In low-income countries, weaning is a period of dietary transition from milk to plant-based foods and a high-risk period for malnutrition. We explored how diet and malnutrition impact hair delta N-15 and delta C-13 in young children by an observational, cross-sectional study in Cox's Bazar District, Bangladesh [255 children, 6-59 months with 19.6% wasted (7.1% severely) and 36% stunted (9.8% severely)]. Hair delta N-15 and delta C-13 exhibited exponential decreases with age, with the loss of one trophic level (3.3 parts per thousand and 0.8 parts per thousand, respectively) from 6 to 48 months, which we associate with the shift from exclusive breastfeeding to complete weaning. After adjustment for age and breastfeeding status, hair isotopic values were unaffected by wasting but lower in severe stunting (-0.45 parts per thousand to -0.6 parts per thousand, P < 0.01). In this population of young children, whose isotopic values in hair primarily depended on age, we failed to observe any effect of wasting, likely due to opposite, compensating effects between dietary and metabolic changes involved. In contrast, we evidenced low delta N-15 and delta C-13 values in severely stunted children that likely indicate chronic exposure to diets low in animal products.
