- Objective: To compare, specifically by age group, proxy-reported food group estimates obtained from the food frequency section of the Children's Eating Habits questionnaire (CEHQ-FFQ) against the estimates of two non-consecutive 24h dietary recalls (24-HDR). Design: Estimates of food group intakes assessed via the forty-three-food-group CEHQ-FFQ were compared with those obtained by a computerized 24-HDR. Agreement on frequencies of intakes (equal to the number of portions per recall period) between the two instruments was examined using crude and de-attenuated Pearson's correlation coefficients, cross-classification analyses, weighted kappa statistics (kappa(w)) and Bland-Altman analysis. Setting: Kindergartens/schools from eight European countries participating in the IDEFICS (Identification and prevention of Dietary- and lifestyle-induced health EFfects In Children and infantS) Study cross-sectional survey (2007-2008). Subjects: Children aged 2-9 years (n 2508, 50.4% boys). Results: The CEHQ-FFQ provided higher intake estimates for most of the food groups than the 24-HDR. De-attenuated Pearson correlation coefficients ranged from 0.01 (sweetened fruit) to 0.48 (sweetened milk) in children aged 2-<6 years (mean = 0.25) and from 0.01 (milled cereal) to 0.44 (water) in children aged 6-9 years (mean = 0.23). An average of 32 % and 31 % of food group intakes were assigned to the same quartile in younger and older children, respectively, and classification into extreme opposite quartiles was <= 12 % for all food groups in both age groups. Mean kappa(w) was 0.20 for 2-<6-year-olds and 0.17 for 6-9-year-olds. Conclusions: The strength of association estimates assessed by the CEHQ-FFQ and the 24-HDR varied by food group and by age group. Observed level of agreement and CEHQ-FFQ ability to rank children according to intakes of food groups were considered to be low.

- Objective: We explored the use of feedback in interactive web-based questionnaires for collecting data on lifestyle factors in epidemiological studies.Design: Here we report from a cohort study on lifestyle factors and upper respiratory tract infections among 1805 men and women. We introduced interactivity in the form of personalized feedback and feedback on a group level regarding dietary intake, physical activity and incidence of infections in web- based questionnaires as incentives for the respondents to continue answering questions and stay in the study.Setting: The study was performed in Sweden.Subjects: All participants were randomly selected from the population registry.Results: Personalized feedback was offered in the baseline questionnaire and feedback on a group level in the five follow-up questionnaires. In total, 88 % of the participants actively chose to get personalized feedback at least once in the baseline questionnaire. The follow-up questionnaires were sent by email and the overall compliance at each follow-up was 83–84 %, despite only one reminder. In total, 74 % completed all five follow-ups. However, the compliance was higher among those who chose feedback in the baseline questionnaire compared with those who did not choose feedback.Conclusions: The results show that it is possible to use feedback in web ques- tionnaires and that it has the potential to increase compliance. The majority of the participants actively chose to take part in the personalized feedback in the baseline questionnaire and future research should focus on improving the design of the feedback, which may ultimately result in even higher compliance in research studies.

- Objective: Measurement errors in dietary data lead to attenuated estimates of associations between dietary exposures and health outcomes. The present study aimed to compare and evaluate different approaches of handling implausible reports by exemplary analysis of the association between dietary intakes (total energy, soft drinks, fruits/vegetables) and overweight/obesity in children. Design: Cross-sectional multicentre study. Setting: Kindergartens/schools from eight European countries participating in the IDEFICS Study. Subjects: Children (n 5357) aged 2-9 years who provided one 24 h dietary recall and complete covariate information. Results: The 24 h recalls were classified into three reporting groups according to adapted Goldberg cut-offs: under-report, plausible report or over-report. In the basic logistic multilevel model (adjusted for age and sex, including study centre as random effect), the dietary exposures showed no significant association with overweight/obesity (energy intake: OR=0.996 (95% CI 0.983, 1.010); soft drinks: OR=0.999 (95% CI 0.986, 1.013)) and revealed even a positive association for fruits/vegetables (OR=1.009 (95% CI 1.001, 1.018)). When adding the reporting group (dummy variables) and a propensity score for misreporting as adjustment terms, associations became significant for energy intake as well as soft drinks (energy: OR=1.074 (95% CI 1.053, 1.096); soft drinks: OR=1.015 (95% CI 1.000, 1.031)) and the association between fruits/vegetables and overweight/obesity pointed to the reverse direction compared with the basic model (OR=0.993 (95% CI 0.984, 1.002)). Conclusions: Associations between dietary exposures and health outcomes are strongly affected or even masked by measurement errors. In the present analysis consideration of the reporting group and inclusion of a propensity score for misreporting turned out to be useful tools to counteract attenuation of effect estimates.

- Objective: To examine the association of breakfast consumption with objectively measured and self-reported physical activity, sedentary time and physical fitness.Design: The HELENA (Healthy Lifestyle in Europe by Nutrition in Adolescence) Cross-Sectional Study. Breakfast consumption was assessed by two non-consecutive 24 h recalls and by a 'Food Choices and Preferences' questionnaire. Physical activity, sedentary time and physical fitness components (cardiorespiratory fitness, muscular fitness and speed/agility) were measured and self-reported. Socio-economic status was assessed by questionnaire. Setting: Ten European cities. Subjects: Adolescents (n 2148; aged 12.5-17.5 years). Results: Breakfast consumption was not associated with measured or self-reported physical activity. However, 24 h recall breakfast consumption was related to measured sedentary time in males and females; although results were not confirmed when using other methods to assess breakfast patterns or sedentary time. Breakfast consumption was not related to muscular fitness and speed/agility in males and females. However, male breakfast consumers had higher cardiorespiratory fitness compared with occasional breakfast consumers and breakfast skippers, while no differences were observed in females. Overall, results were consistent using different methods to assess breakfast consumption or cardiorespiratory fitness (all P <= 0.005). In addition, both male and female breakfast skippers (assessed by 24 h recall) were less likely to have high measured cardiorespiratory fitness compared with breakfast consumers (OR = 0.33; 95% CI 0.18, 0.59 and OR = 0.56; 95 % CI 0.32, 0.98, respectively). Results persisted across methods. Conclusions: Skipping breakfast does not seem to be related to physical activity, sedentary time or muscular fitness and speed/agility as physical fitness components in European adolescents; yet it is associated with both measured and self-reported cardiorespiratory fitness, which extends previous findings.

- Objective: The Nordic countries have published joint dietary recommendations, the Nordic Nutrition Recommendations (NNR), since 1980. We evaluated adherence to the NNR as a measure of a healthy diet and its potential association with self-reported upper respiratory tract infection (URTI). Design: A prospective, population-based study with a follow-up period of 4 months. Dietary intake was assessed using a semi-quantitative FFQ with ninety-six items, along with other lifestyle factors, at baseline. URTI was assessed every three weeks. A Poisson regression model was used to control for age, sex and other confounding factors. Setting: A middle-sized county in northern Sweden. Subjects: Swedish men and women (n 1509) aged 20-60 years. Results: The NNR include recommendations on macronutrient proportions, physical activity and intake of micronutrients, sodium, fibre and alcohol. We found that overall adherence to the NNR was moderately good. In addition, we found that high adherence to the NNR (>5.5 adherence points) was not associated with a lower risk of URTI (incidence rate ratio (IRR) 0.89, 95% CI 0.73, 1.08) compared with low adherence (<4.5 adherence points). When investigating individual components of the NNR, only high physical activity was associated with lower URTI risk (IRR=0.82, 95% CI 0.69, 0.97) whereas none of the dietary components were associated with risk of URTI. Conclusions: Overall adherence to the NNR was moderately good. Overall adherence to the NNR was not associated with URTI risk in our study. However, when investigating individual components of the NNR, we found that high physical activity was associated with lower URTI risk.

- Objective To estimate the contribution of television (TV) food advertising to the prevalence of obesity among 6–11-year-old children in Australia, Great Britain (England and Scotland only), Italy, The Netherlands, Sweden and the United States. Design Data from contemporary representative studies on the prevalence of childhood obesity and on TV food advertising exposure in the above countries were entered into a mathematical simulation model. Two different effect estimators were used to calculate the reduction in prevalence of overweight and obesity in the absence of TV food advertising in each country; one based on literature and one based on experts’ estimates. Setting Six- to eleven-year-old children in six Western countries. Results Estimates of the average exposure of children to TV food advertising range from 1·8 min/d in The Netherlands to 11·5 min/d in the United States. Its contribution to the prevalence of childhood obesity is estimated at 16 %–40 % in the United States, 10 %–28 % in Australia and Italy and 4 %–18 % in Great Britain, Sweden and The Netherlands. Conclusions The contribution of TV advertising of foods and drinks to the prevalence of childhood obesity differs distinctly by country and is likely to be significant in some countries.
