TL;DR
Researchers adapted a digital dietary recall tool for South Asia, enabling detailed dietary assessments across diverse populations.
Contribution
The adaptation of Intake24 with a region-specific food database for South Asia, enabling large-scale dietary assessment.
Findings
The South Asia Intake24 database included 2283 food items with good regional coverage.
Median recall completion time was 13 minutes, with 99% of recalls including more than 8 food items.
Energy intake varied by age and sex, with younger and male participants reporting higher intake.
Abstract
South Asia’s diverse food supply, food preparations, and eating behaviors require dietary instruments that reflect the consumption patterns of South Asians to enable context specific dietary assessment. Such instruments are not readily available for detailed dietary assessment at scale in South Asia. We describe the adaptation, implementation, and performance evaluation of Intake24, an open-source digital 24-h dietary recall tool, for dietary assessment in South Asia. We adapted Intake24 for dietary assessment in the South Asia Biobank (SAB), a large population-based study in Bangladesh, India, Pakistan, and Sri Lanka. Intake24 adaptation encompassed the development of a South Asian food database with commonly consumed foods, linked with corresponding portion sizes, food probes, and nutrient information. Trained interviewers conducted the 24-h recalls. Performance of Intake24 was…
