ABSTRACT
The current study sought to identify characteristics that may be associated with the misreporting of food energy intake (EI) in urban South African women. A total of 198 women (61 black; 76 of mixed ancestry; 61 white) completed a quantified food frequency questionnaire; from which daily energy and macronutrient intake were calculated. Body composition (body mass index [BMI]; percentage of body fat); body image (Feel-Ideal Difference index and Body Shape questions) and socio-economic status (SES) (household density and asset index) were also measured. Food EI in relation to estimated basal metabolic rate ratio that was less than 1.05 represented under-reporting; whereas a ratio greater than 2.28 represented over-reporting. Results suggested that 26of the participants under-reported; 64adequately reported and 10over-reported. Participants who under-reported had a higher BMI (p 0.01) and higher percentage of body fat (p 0.05) than those who adequately and over-reported. The majority of under-reporters were black (38) versus 21under-reporters of mixed ancestry and 20white under-reporters (p 0.01). Eighty-three per cent of black under-reporters were obese. On the other hand; a majority (63) of overweight women of mixed ancestry and a majority (50) of white normal-weight women under-reported their food EI. Under-reporters reported a lower intake of dietary fat (p 0.01) and a higher intake of dietary protein (p 0.01) than adequate or over-reporters. Food EI reporting was not influenced by SES or body image. In conclusion; results suggest that food EI reporting is influenced by body size; and may be ethnic-specific in South African women
