Optimisticself-assessments of unhealthy diets are associated with positive indicators of health and health behaviours inDanish adults.. Poster session presented at 11th Nordic Nutrition Conference 2016 , Gothenburg, Sweden.Optimistic self-assessments of unhealthy diets are associated with positive indicators of health and health behaviours in Danish adults Background and aim Optimistic self-assessments of unhealthy diets have been suggested as a potential barrier to the promotion of healthier eating practices. The aim of this study was to examine the extent to which Danish adults with unhealthy diets assess the healthiness of their diets optimistically and to examine socio-demographic, health and behaviour characteristics associated with this optimistic self-assessment.  Methods • Cross sectional analysis including 3014 adults (18-75 y) (M:1464, W:1550) • Data derived from The Danish National Survey of Diet and Physical Activity 2011-2013 (seven-days pre-coded food diaries, structured face-to-face interviews, anthropometric measures) • A diet index on saturated fat, added sugar, fruits and vegetables, fish and wholegrain was applied to divide individuals into tertiles of healthy, somewhat healthy and unhealthy diets • Estimated diet quality was compared with individuals’ self-assessed diet healthiness (to a high degree healthy, to some degree healthy and not healthy)  • Optimistic self-assessment was defined as being among the lowest tertile ‘unhealthy diets’ and assessing own diets as healthy to a high degree (highly optimistic) and to some degree (somewhat optimistic) • Logistic regression models were used to examine characteristics associated with optimistic self-assessments of unhealthy diets         Figure 1. Classification of self-assessments of unhealthy diets Results Among individuals with unhealthy diets, 13 % assessed their diets as healthy to a high degree, 42 % to some degree and 45 % were realistic about their unhealthy diets. Optimistic self-assessments of unhealthy diets were associated with increasing age, excellent self-rated health, normal weight and a moderate physical activity level.  Table 1. Factors significantly associated with optimistic self-assessments among adults with unhealthy dietsa (diet index score <3.01) (outcome variable: highly optimistic vs. realistic) (Total N=3014, active n=497)                a Included factors: gender, age, education, income, weight status, abdominal weight status, self-reported high cholesterol, self-rated health, slimming diet, self-assessed leisure time physical activity, smoking habits. Age and education were kept in the model b Tested using logistic regression (P<0.05) c 1 % was underweight (BMI <18.5)  Conclusions A considerable percentage of Danish adults with unhealthy diets were optimistic about the healthiness of their diets. This tendency was more likely among older adults and adults with positive indicators of health and health behaviours. In the promotion of dietary health, it is important to acknowledge differences in dietary health assessments among lay people and nutrition professionals. Possible reasons for optimistic self-assessments should be further explored.    :  Sørensen MR1, Matthiessen J1, Holm L2, Knudsen VK1, Andersen EW3, Tetens I1 1 National Food Institute, Technical University of Denmark 2 Department of Food and Resource Economics, University of Copenhagen  3 Department of Applied Mathematics and Computer Science, Technical University of Denmark  National Food Institute, Technical University of Denmark Correspondence to: Mette Rosenlund Sørensen mers@food.dtu.dk OR 95% CI P-valueb Age   18-24 25-44 45-64 65-75  0.05 0.14 1.00 2.84  0.02-0.15 0.07-0.27  1.42-5.69 <0.001 <0.001 <0.001  0.003 Self-rated health  Excellent Very good Good Fair/poor  1.00 0.36 0.34 0.56   0.19-0.69 0.17-0.65 0.24-1.30 0.004  0.002 0.001 0.177 Weight status  Normal weightc (BMI <25) Overweight (BMI 25 - <30) Obese (BMI ≥30)  1.00 0.40 0.11   0.23-0.71 0.05-0.24 <0.001  0.002 <0.001 Physical activity, leisure time  Vigorous  Moderate Light Sedentary  0.49 1.00 0.48 0.36  0.14-1.78  0.27-0.85 0.15-0.83 0.037 0.281  0.011 0.017 Self-assessed diet healthiness To a high degree healthy To some degree healthy Not healthy  Estimated diet index score, lowest tertile  Highly  optimistic self-assessment   Somewhat optimistic self-assessment  Realistic self-assessment  Colourbox.dk
