Abstract
Estimates of food consumption and macronutrient intake were obtained f rom a randomly selected population sample (2%) of 1015 adolescents age d 12 and 15 years in Northern Ireland during the 1990/1991 school gear . Dietary intake was assessed by diet history with photographic album to estimate portion size. Reported median energy intakes were 11.0 and 13.1 MJ/d for boys aged 12 and 15 years respectively and 9.2 and 9.1 MJ/d for girls of these ages. Protein, carbohydrate and total sugars i ntakes as a percentage of total energy varied little between the age a nd sex groups and were approximately 11, 49 and 20% respectively of da ily total energy intakes. Median dietary fibre intakes were approximat ely 20 and 24 g/d for boys aged 12 and 15 years respectively and 18 an d 19 g/d for girls of these ages. Major food sources of energy (as a p ercentage of total energy intakes) were bread and cereals (15-18%), ca kes and biscuits (12-14%), chips and crisps (13-14%), dairy products ( 9-11%), meat and meat products (9-11%) and confectionery (9%). Fruit a nd vegetable intakes were low at about 2.5% and 1.5% respectively of t otal energy intakes. Median fat intakes were high at 39% of total dail y energy intakes. Major food sources of fat as a percentage of total f at intakes were from the food groupings: chips and crisps (16-19%), me at and meat products (14-17%), fats and oils (14-16%), cakes and biscu its (13-16%) and dairy products (12-15%). Median intakes of saturated fatty acids were also high at approximately 15% of daily total energy intake while intakes of monounsaturated fatty acids averaged 12% of da ily total energy intake. Median polyunsaturated fatty acid (PUFA) inta kes were low, comprising 5.2 and 5.5% of daily total energy intake for boys aged 12 and 15 years respectively and were lower than the PUFA i ntakes (5.9 and 6.3% of daily total energy intake) for girls of these ages. About 1.3% for boys and 1.4% for girls of daily total energy int ake was in the form of n-3 PUFA. Ca and Mg intakes were adequate for b oth sexes. Based on these results, some concern about the dietary habi ts and related health consequences in Northern Ireland adolescents app ears justified.
