The objective of this paper is to perform a dietary pattern analysis of Nepali women of childbearing age.
The study extracted data from 2994 non-pregnant women between 15 to 49 years of age (mean age 27 years) from an ongoing nationally representative, multi-year household panel survey performed in 21 districts of Nepal (between 2013-14). Using a food frequency questionnaire (FFQ), women were asked about what they ate and how often they consumed an individual food in the last 24 hours and within a 7-day period. Principal Component Analysis (PCA) was done to generate dietary patterns by computing coefficients for each of the 49 food items listed in the FFQ.
The top four components generated by PCA explained 20% of the variation in the dietary data. Of these, Components 1 and 2 each explained more than 6 % of variation while components 3 and 4 each explained 3% of variation. Component 1 included oil, diverse animal source foods (ASF) and wheat. Vegetable oil was the main source of fat while goat and eggs were protein sources. Component 1 had Vitamin A rich fruits and dark green leafy vegetables. Component 2 included rice, potato, noodles and snack foods (such as puffed rice, beaten rice, biscuits, popcorn) as sources of carbohydrates, vegetable oil as a source of fat and lentils as a source of plant based protein. Vegetables included okra and gourd, and fruits included apples and mangoes. Component 3 included a pattern with a predominant amount of grains (rice, wheat, millet), milk, and ASFs. Component 4 included lentils, ASFs, cauliflower and cabbage.
PCA analysis of dietary data on non-pregnant women in Nepal yielded four major dietary patterns. Pattern 1 was termed as a nutrient and energy dense diet pattern. Pattern 2 was primarily energy dense and was termed as a traditional Nepali diet pattern. Pattern 3 and 4 were primarily energy dense. Study participants who followed the dietary pattern 1 were more likely to meet the dietary requirements than those in pattern 2. Future research should focus on quantitatively assessing diets of Nepali women to ascertain the identified dietary patterns.
