Résumé
Background For the last 22 years the prevalence of obesity increased from 14.9% to 26.9%. Taking control of the obesity epidemic is one of the major Public Health UK problems. Low quality diet leads to obesity, nutrient deficiency and development conditions such as CVD and type 2 diabetes. Balanced diet may improves short term health and helps to achieve and maintain a healthy weight. Lots of Public Health initiatives were developed to provide people with general knowledge about balanced diet and to improve food attitudes and overall health literacy. However, it is still hard to evaluate how efficient these programs are at present. Aims This study is aimed to evaluate the level of awareness of the UK population about the most recent Public Health UK recommendations related to the diet and lifestyle and to assess the relationship between the nutrition knowledge and the actual dietary behaviour . Methods The cross-sectional study based on quantitative data collection and analysis was conducted to evaluate the relationship between nutrition knowledge score, dietary behavior and dietary intake. The new nutrition knowledge questionnaire was designed based on existed validated GNKQ. Nutrition knowledge questionnaire was used to evaluate the nutritional knowledge score of UK adults. A 24-hour recall was also conducted for each participant. Dietplan 7 was used to convert 24HR dietary data to the nutrient content. Population 50 members of the general UK public were recruited on the volunteering basis via their places of living or work across the London boroughs to represented studied general UK population. All participants completed the nutrition knowledge questionnaire. 94% (n=47) of participants additionally provided their personal details and completed 24HR. 47 participants, the mean age 34 years (s.d.=7) were almost equal proportions of 24 male and 23 female. Mean population BMI=23.3 (s.d.=3.3) and 25% (n=12) of the population were classified as overweight or obese. Results Nutrition knowledge score correlates with the age groups (18-24; 25-34; 35-44; 45-54 years) (p=0.04, r = 0.32) and those who had (n=8) and did not have (n=42) nutrition qualification (p < 0.01, r = 0.53). 87% of the studied population didn't reach their EAR for energy intake. Mean energy intake below the EAR level on 34% in male and on 21% in female populations. Dietary nutrient intake of the population was close to the latest NDNS UK data. No correlation between nutrition knowledge score and certain food or nutrient intake found (n=47, p > 0.05), except weak negative correlation between sugar knowledge score and free sugars intake (p = 0.04, r= - 0.3). 81% of the population (n=38) aware of ‘5-a-day’ recommendation but only 22% of them achieved it (n=8). 64% (n=30) of the studied population aware of vitamin D supplementation requirements but only 30% (n=9) of these people are taking it. 85% of the population (n=33) are using front package labels and would prefer organic products to conventional. Those participants who had nutrition related qualifications (n=5) consumed 30% less Fat, 31% less Saturated Fat and 31% less salt than average study population (n=42). Conclusion Descriptive data of chosen group is different from the average UK population. Larger population groups with different backgrounds, the unified assessing mechanism and score system are desirable to overcome systematic bias and difficulty in finding the connection between nutrition knowledge and food choice.
