The smoking and dietary behaviour of lambeth schoolchildren II. the relationship between knowledge, attitudes and behaviour

As part of a study designed to examine the effect of a health education programme on 10-year-old schoolchildren, information was obtained on the children's knowledge, attitudes and behaviour concerning two health hazards, namely smoking and obesity. Cross sectional analyses showed that children who smoked were as aware of the health hazards of smoking as non-smokers but were less likely to hold anti-smoking attitudes. They were also more likely to think of themselves as “naughty” and “silly”. Conversely, children who subsequently adopted smoking were less aware of the health hazards of smoking than those who remained non-smokers. There was good evidence that obese children possessed more nutritional knowledge than the non-obese, and their attitudes to diet differed little. No relationship was demonstrated between reported energy intake and obesity, either cross sectionally or longitudinally. Relationships between knowledge and attitudes towards nutrition and the development of obesity were investigated, but there was only one significant finding, namely that boys identifying correct statements about nutrition put on less fat than other boys.
