     of the Nutritim Study 
     
     cmducted by Professors

     The study deals with 
     
     Sd‘lOOl 1111011 and nutriticn 
     
     education as influences 
     
     on adolescent food 
     
    
   
   
    
     behaviour. The  
     
    
   
   
    
     phase was carried out in 
     
     January and February of 
     
     1976 in six jmior high 
     
     schools in the province. 
     
    

    
     Students carpleted a 
     
     series of questimnaires 
     
     cn personal and family 
     
     backgromd, nutritim 
     
     knowledge and attitudes, 
     
     food preferences and feed 
     
     intake during the school 
     
     day. Of the 938 students 
     
     surveyed, 45 per cent were

     were in Grade 9. 'Ihe 
     
     median age was 14 years. 
     
     'Jhere were slightly more 
     
     males than females.

     and the other receiving 
     
     the sane nutrition 
     
     education unit in 
     
     combination with a sdioo 
     
     lunch program. ' - 'Ihe " 
     
     nutrition education program 
     
     emphasized consrmption of 
     
     milk, fruits and 
     
     vegetables as these were 
     
     the problem areas 
     
     identified by a 
     
     preliminary study ccn- 
     
     ducted in 1975. 
     
    
   
   
    
     'Ihe study investigated 
     
     the adequacy of the 
     
     dietary intake of, the 
     
     students during the sd'iool 
     
     day. Analysis of the food 
     
     intakesrevealed that the 
     
     intake of calories, calciun 
     
     iron and vitamin C were 
     
     low. Approximately cne- 
     
     third of the students had 
     
     caloric intakes in the 
     
     inadequate category, "(less 
     
     than the two-thirds of the 
     
     recommended anomts for 
     
     this age group.) Fifty- 
     
     eight percent of the males 
     
     and forty-seven percent of 
     
     the females had calcium 
     
     intakes in the saneg 
     
     category. ' 
     
    

    
     A dietary deficit of iron 
     
     in females was apparent:
