Summary
This paper by Kennedy et al., published in the Journal of Nutrition in 2010, evaluates the utility of dietary diversity scores as low-cost, practical proxies for assessing micronutrient adequacy at the population level. The study likely draws on dietary recall or food frequency data to correlate diversity metrics with nutrient intake adequacy across multiple micronutrients. It contributes methodological evidence supporting the use of dietary diversity as a monitoring tool in nutrition surveillance and food security assessments, particularly in low- and middle-income country contexts.
UK applicability
This research is primarily orientated towards nutrition monitoring in resource-limited international settings, though its methodological insights on dietary diversity metrics are relevant to UK public health surveillance and dietary assessment frameworks, including efforts to monitor diet quality across socioeconomic groups.
Key measures
Dietary diversity score (DDS); probability of adequate micronutrient intake; mean adequacy ratio (MAR); food group counts
Outcomes reported
The study examined the relationship between dietary diversity scores and micronutrient adequacy, assessing whether simple diversity metrics can reliably predict the probability of adequate micronutrient intake across population groups.
