title: Nutrition promotion and dietary change at off-shore oil installations in the Norwegian sector of the North Sea.
abstract: OBJECTIVE
  This paper examines whether diet had changed at platforms in the Norwegian sector of the North Sea between 1985 and 1993 and if this was caused by nutrition promotive activities, including the use of a health handbook (HHB).
  
  
  METHODS
  The report is based on two cross-sectional surveys, one in 1985 and one in 1993, with special reference to cardiovascular risk. Standardised questionnaires, structured and open interviews were used, incorporating information on food intake and availability, and socioeconomic variables.
  
  
  METHODS
  The study population was 194 healthy men in 1985 and 336 in 1993. The mean age was 35 years in 1985 (range 18-57) and 38 (range 21-59) in 1993.
  
  
  RESULTS
  From 1985 to 1993 the mean intake of foods and nutrients changed in the same direction as recommended by the Norwegian National Nutrition Council and according to the HHB. The mean energy percentage from fat was 12% lower in 1993 than in 1985. Overall 56% of the workers said they had changed diet since 1985. Those who had changed, consumed more cereals, fruits, more low fat milk, and more fruit juice, and had lower energy percentage from fat, lower intake of dietary cholesterol, more intake of vitamin C and dietary fibre in 1993 than those who had not changed. About 70% of those who had received the HHB had changed their diet, against 50% of those who had not. The use of the HHB was inversely related to intake of energy, energy from fat, and dietary cholesterol, and positively related to vitamin C and dietary fibre.
  
  
  CONCLUSIONS
  It is concluded that the dietary changes are likely to be caused by the interventions, including the HHB.
