Relatively fewer valid Godin scores were returned by those who left school aged < 15 years ( 36.5 % ) than aged 18 and over ( 50.5 % ) , manual workers ( 39.5 % ) than non-manual ( 49.5 % ) and those with an elevated cholesterol ( > 5 mmol ) ( 34.7 % ) than those with a lower cholesterol ( 44.4 % ) but multivariate analysis identified that only school leaving age ( p = 0.047 ) was of statistical significance.Relatively fewer valid DINE scores were returned by manual than non-manual workers ( fibre : 80.8 % v 86.8 % ; fat : 71.2 % v 80.0 % ) , smokers ( fibre : 72.6 % v 84.7 % ; fat : 67.5 % v 76.9 % ) , patients with diabetes ( fibre : 75.9 % v 82.9 % ; fat : 66.9 % v 75.8 % ) and those with cholesterol > 5 mmol ( fat : 68.2 % v 76.2 % ) but multivariate analysis showed statistical significance only for smoking ( fibre : p = 0.013 ; fat : p = 0.045 ) , diabetes ( fibre : p = 0.039 ; fat : p = 0.047 ) , and cholesterol ( fat : p = 0.039 ) .
