    Eating out of home (OH) is nutritionally important in some developing countries. This study identifies the factors associated with eating OH in Vietnamese adolescents. Data were obtained from a cross-sectional cluster survey of 502 adolescents in rural and urban areas in Vietnam. Factors associated with eating OH were recorded with a Likert scale and analysed using factor analysis. Data on eating OH was collected using a frequency questionnaire and a 1-day 24h recall. A first pattern 'Convenience' incorporated preparation time, price, variety, taste, proximity and social aspects as items associated with eating OH. A second pattern 'Nutritional and food safety concerned' reflects concerns with regard to hygiene, fat and salt content of the food prepared OH. Adolescents characterised by the convenience pattern were more likely (OR=1.51, P<0.001) to eat OH more frequently. The highest tertile of the Nutritional and food safety concerned pattern was less likely (OR=0.61, P=0.03) to eat OH compared to lower tertiles. Both patterns were not associated with the % energy from eating OH per day. Convenience and to a lesser extent Nutritional and food safety concerns are significant factors associated with the frequency of eating OH in Vietnamese adolescents.
