Kassem, N.O., Lee, J.W., Modeste, N.N. Johnston, P.K.. "Understanding reduced-fat milk consumption among female adolescents using the the theory of planned behavior.." J Ped Neonat 2.2 (2005): 1-10. ( 1/2005 )
Calcium is an essential dietary nutrient and a major constituent of bone mieral. Adolescents need to be in positive calcium balance to meet skeletal demands. However, studies have shown that their calcium intake s well below the Recommended dietary Allowance (RDA), and even farther below the latest Dietary Reference Intake(DRI) recommendations.
This study identified factors that influence reduced-fat milk consumption among 710 female students, aged 13-18 years, attending north Los Angeles County public high schools. Participants completed a group-administered theory of planned behavior based questionnaire.
The majority of the participants, 89.6%, reported that they currently drink some kind of milk. Of those who reported that they drink milk, 64.3% reported that they currently drink reduced-fat milk or skim milk. Attitude, subjective norm and perceived behavioral control were each significant predictors of intention to drink reduced-fat milk and together explained 66% of its variance. The strongest predictor was attitude, followed by perceivd behavioral control and subjective norm. Taste and possible health benefits were the primary predictors of attitude: parents' opinions predicted subjective norm; and availability of reduced-fat milk at home, school and in vending machines prediceted perceived control.
This study findings suggest points of intervention in increasing reduced-fat milk consumption among female adolescents.
