Determinants of knowledge and attitudes about sugar and the association of knowledge and attitudes with sugar intake among adults: A systematic review

14 / 11 / 18

Finding:

A number of factors influence attitudes and knowledge about sugar but overall the evidence is weak in this field.

Summary:

A systematic review was conducted to identify factors influencing adults’ knowledge and attitudes about sugar, and to determine if there is an association between knowledge and attitudes about sugar and sugar intake. Of 3287 studies, only 22 met review objectives. Factors identified that influenced attitudes and knowledge about sugar were: individual liking of sugary food; interpersonal (attitudes of peers); and environmental factors (media, health professional and food labelling). The authors concluded the quality of the studies included was weak and application of the Knowledge-Attitude-Behaviour model for understanding sugar intake is limited.
