Abstract
INTRODUCTION: Under-reporting of energy intake is a common cause of bias in nutritional studies. This study was aimed at examining the extent of under-reporting of energy intake and its related characteristics among respondents in MANS 2003 and MANS 2014. METHODS: The present study analysed energy intakes of 9,624 adults aged 18-59 years old from the Malaysian Adult Nutrition survey in year 2014 (2,890 respondents) and 2003 (6,734 respondents) using a single 24-hour diet recall. Basal metabolic rates were calculated from the age- and gender-specific equations of Schofield. Under-reporting was defined as an energy intake: BMR ratio <1.2 as proposed by Goldberg. RESULTS: Under-reporting has increased significantly (p<0.001) from 53% in 2003 to 61% in 2014. In both surveys, under-reporting increased with higher BMI and older age-group. It was higher among women than men, lowest among those with primary schooling or below, and those living in Peninsular Malaysia. It was higher among rural respondents in 2014 but higher among urban respondents in 2003. Intake of energy and micronutrients increased when under reporters were excluded. CONCLUSION: Under-reporting was prevalent in both the nationwide MANS, and is associated with BMI, age, gender, education level, strata and location. It is important to take this into account when assessing dietary intake in population-based studies.
