Eating location is associated with the nutritional quality of the diet in Norwegian adults.

OBJECTIVE

To study the association between dinner eating location and the nutritional quality of the specific dinner meal and the whole-day dietary intake and to compare the diets of those consuming ≥25% of energy out of home and at school/work (SOH; substantial out-of-home eaters) with those consuming <25% of energy out (NSOH; non-substantial out-of-home eaters).

DESIGN

Cross-sectional dietary survey using two non-consecutive 24 h recalls. Recorded eating locations were at home, other private households, work/school, restaurant/cafeteria/fast-food outlet and travel/meeting.

SETTING

Nationwide, Norway (2010-2011).

SUBJECTS

Adults aged 18-70 years (n 1746).

RESULTS

Dinners at restaurants and other private households were higher in energy than home dinners (P < 0.01). Restaurant dinners contained less fibre (g/MJ; P < 0.01) and had a higher percentage of alcohol consumers (P < 0.05), while dinners at other private households had a higher percentage of energy from sugar (P < 0.001) and a higher percentage of consumers of sugar-sweetened beverages (P < 0.05) than home dinners. Most differences between dinners consumed at different eating locations were also observed in dietary intakes for the whole day. SOH-eaters had a higher energy intake (P < 0.01), a higher percentage of energy from sugar (P < 0.01) and a lower fibre intake (P < 0.01) than NSOH-eaters. The percentages of consumers of alcohol and sugar-sweetened beverages were higher (P < 0.01) among SOH-eaters.

CONCLUSIONS

Dinner eating location was significantly associated with the nutritional quality of the diet, both for the specific dinner meal and for whole-day intake. Our data generally point to healthier dinners being consumed at home. SOH-eaters had a less favourable dietary intake than NSOH-eaters.
