OBJECTIVES: Culturally appropriate dietary assessments are lacking in many low-income countries including Nepal. Here we examined the reproducibility and validity of a dietary screener which was translated and adapted to assess diet quality among pregnant Nepalese women. METHODS: A pilot cohort of singleton pregnant women (N = 101; age 25.9 ± 4.1 years) was recruited from a tertiary, periurban hospital in Nepal. An adapted Nepali version of the PrimeScreen questionnaire, assessing weekly consumption frequency of 12 healthy and 9 unhealthy food groups, was administered twice and a month apart in both the 2(nd) and 3(rd) trimester. Up to four inconsecutive 24-hr dietary recalls (24-HDRs) were also completed each trimester and utilized as the reference method for validation. For each trimester, data from multiple 24-HDRs were averaged across days, and items were grouped to match the classification and the three weekly consumption categories (0–1, 2–3 or 4 + servings/week) of the 21 food groups represented on the PrimeScreen. Gwet's agreement coefficients (AC1) were used to evaluate the reproducibility and validity of the adapted PrimeScreen against the 24-HDRs in both 2(nd) and 3(rd) trimester. RESULTS: In the 2(nd) trimester, the adapted PrimeScreen demonstrated good to excellent reproducibility (AC1 > 0.6) for majority of the food groups; the reproducibility was moderate for eggs (AC1 = 0.4), and poor (AC1 80%) between the PrimeScreen and 24-HDR for 80% of the food groups in both 2(nd) and 3(rd) trimester. CONCLUSIONS: The adapted PrimeScreen questionnaire appears to be a reliable and valid instrument for assessing the dietary intake of most food groups among pregnant women in Nepal.
