Prevalence of diabetes, metabolic syndrome, hypertension and obesity have reached epidemic levels. Sri Lanka is a low-middle income country undergoing a nutritional transition. However, the weighed intake method also has its own limitations, such as higher cost, substantial subject burden and impracticality for use among a larger sample. Therefore, some developed countries have used the 7-day weighed record (7DWR) as a reference method to overcome many limitations of the dietary recalls. However, the 24 DR method has its’ own limitations, such as misreporting, recall bias and poor representation of the usual intake. Single or multiple 24-hour dietary recalls (24DR) are widely used for national level nutritional surveys. However, different methods have been used to measure dietary intake at a population level, and there is no agreement on which tool best reflects the habitual dietary intake pattern. Results obtained from 24DR method under-estimated the nutrient intakes as compared to the 7DWFR method.Īssessment of dietary intake among different populations is essential to monitor ongoing nutritional transition, and for development of appropriate interventions.
Several participants reported difficulties in using the 7DWR method and some reported an alteration in their diet pattern when this method was used. However, there was no statistically significant difference in energy percentages for macronutrients, between the two methods. Mean (SD) values for energy and major macronutrients were significantly lower for 24DR as compared to 7DWR. ResultsĪ total of 76 participants completed both 24DR and 7DWR. In addition, qualitative data were collected from 30 participants, chosen randomly, on the feasibility of the 7DWR as a dietary assessment method. The nutrients were analyzed using Nutrisurvey Software. The 24DRs were performed on a random day and the subjects were instructed to complete 7DWR from the next day onwards. One hundred adults were randomly selected from a representative sample from Sri Lanka.
The present study aims to compare the energy and nutrient intakes, estimated from 7DWR and 24-hour dietary recall (24DR), among a group of adults. The 7-day weighed food record (7DWR) method involves an individual weighing of each and every food item prior to consumption, and is considered as a reference method in many situations. Misreporting, recalling and overestimation are common problems with dietary assessment methods currently available.
