Abstract/OtherAbstract:
OBJECTIVE: While socio-economically disadvantaged adolescents tend to have poor dietary intakes, some manage to eat healthily. Understanding how some disadvantaged adolescents restrict high-energy foods and beverages may inform initiatives promoting healthier diets among this population. The present investigation aimed to: (i) identify disadvantaged adolescents' high-energy food and beverage intakes; and (ii) explore cross-sectional and longitudinal associations between intrapersonal, social and environmental factors and disadvantaged adolescents' high-energy food intakes. DESIGN: Longitudinal online surveys were completed at baseline (2004-2005) and follow-up (2006-2007), each comprising a thirty-eight-item FFQ and questions examining intrapersonal, social and environmental factors. SETTING: Thirty-seven secondary schools in metropolitan and non-metropolitan Victoria, Australia. SUBJECTS: Of 1938 adolescents aged 12-15 years participating at both time points, 529 disadvantaged adolescents (whose mothers had low education levels) were included in the present investigation. RESULTS: At baseline and follow-up, respectively 32 % and 39 % of adolescents consumed high-energy foods less frequently (≤2 high-energy food meals/week); 61 % and 65 % consumed high-energy beverages less frequently (≤1 time/d). More girls than boys had less frequent high-energy food intakes, and baseline consumption frequency predicted consumption frequency at follow-up. Adolescents with less frequent consumption of high-energy foods and beverages seldom ate fast food for main meals, reported reduced availability of high-energy foods at home and were frequently served vegetables at dinner. CONCLUSIONS: Nutrition promotion initiatives could help improve disadvantaged adolescents' eating behaviours by promoting adolescents and their families to replace high-energy meals with nutritious home-prepared meals and decrease home availability of high-energy foods in place of more nutritious foods.
