Abstract

Associations between an unhealthy diet and overweight and the presence of asthma are reported. The aims of this study were to assess whether the intake of nutrients and food items in adolescents with asthma differs from that of healthy adolescents, whether the intake was in accordance with the Nordic Nutrition Recommendations (NNR) or whether possible relationships were confounded by body composition. A four-day-validated 18-page pre-coded food diary was completed by 169 13- to 14-year-old adolescents, 93 with asthma and 76 healthy control subjects, in addition to clinical assessment, anthropometric measurements, lung function and skin prick tests. Neither intake of added sugar, snacks nor saturated fat was associated with asthma. All groups had an intake of saturated fat and added sugars exceeding the NNR, while the intake of fruits and vegetables, fibre and vitamin D was lower than recommended. The intake of folate, calcium, magnesium and iron was lower than recommended for girls with asthma and healthy girls. The intake of vitamin C was satisfactory for all groups. Body composition did not influence eating habits, and the prevalence of overweight was similar in the two groups. The dietary intake among Norwegian adolescents in general had a potential for improvement. As girls have a lower energy intake than boys, they have a larger demand of quality of the diet. Additional dietary research in adolescents with asthma is recommended.
