Abstract
PURPOSE: To compare intakes of dietary iron and enhancers and inhibitors of iron absorption between overweight/obese (OW/OB) adolescents and their normal weight (NW) peers, and between parental education levels stratified by weight status. METHODS: This was a comparative cross-sectional study of adolescents (n 121 OW/OB and n 102 NW) aged 12-14 years, attending a secondary school in Nonthaburi province, Thailand. Socio-demographic data were obtained from participants' parents using a questionnaire. Participants recorded their intakes for 3 non-consecutive days, using a prospective food record. RESULTS: Compared with NW adolescents, OW/OB adolescents consumed more total protein and animal protein after adjustment for energy intake (both p = 0.047). OW/OB adolescents whose mothers were less educated consumed more total iron and available iron after adjustment for energy intake, compared with their OW/OB peers whose mothers were more educated (p = 0.045 and p = 0.040). NW adolescents with more highly educated mothers had higher absolute and energy-adjusted fibre intakes (both p = 0.047). However, NW adolescents of mothers with a high-intermediate level of education consumed less calcium, after adjustment for energy intake (p = 0.028). CONCLUSIONS: OW/OB adolescents with less educated mothers had higher energy-adjusted intakes of iron and available iron. Dietary differences in OW/OB adolescents relative to maternal education, and other socioeconomic indicators, should be explored in a nationally representative data set.
