EVIDENT Smartphone App, a New Method for the Dietary Record: Comparison With a Food Frequency Questionnaire (Preprint)

BACKGROUND More alternatives are needed for recording people’s normal diet in different populations, especially adults or the elderly, as part of the investigation into the effects of nutrition on health. OBJECTIVE The aim of this study was to compare the estimated values of energy intake, macro- and micronutrient, and alcohol consumption gathered using the EVIDENT II smartphone app against the data estimated with a food frequency questionnaire (FFQ) in an adult population aged 18 to 70 years. METHODS We included 362 individuals (mean age 52 years, SD 12; 214/362, 59.1% women) who were part of the EVIDENT II study. The participants registered their food intake using the EVIDENT app during a period of 3 months and through an FFQ. Both methods estimate the average nutritional composition, including energy intake, macro- and micronutrients, and alcohol. Through the app, the values of the first week of food recording, the first month, and the entire 3-month period were estimated. The FFQ gathers data regarding the food intake of the year before the moment of interview. RESULTS The intraclass correlation for the estimation of energy intake with the FFQ and the app shows significant results, with the highest values returned when analyzing the app’s data for the full 3-month period (.304, 95% CI 0.144-0.434; P<.001). For this period, the correlation coefficient for energy intake is .233 (P<.001). The highest value corresponds to alcohol consumption and the lowest to the intake of polyunsaturated fatty acids (r=.676 and r=.155; P<.001), respectively. The estimation of daily intake of energy, macronutrients, and alcohol presents higher values in the FFQ compared with the EVIDENT app data. Considering the values recorded during the 3-month period, the FFQ for energy intake estimation (Kcal) was higher than that of the app (a difference of 408.7, 95% CI 322.7-494.8; P<.001). The same is true for the other macronutrients, with the exception g/day of saturated fatty acids (.4, 95% CI −1.2 to 2.0; P=.62). CONCLUSIONS The EVIDENT app is significantly correlated to FFQ in the estimation of energy intake, macro- and micronutrients, and alcohol consumption. This correlation increases with longer app recording periods. The EVIDENT app can be a good alternative for recording food intake in the context of longitudinal or intervention studies.

Longitudinal Changes

1. Longitudinal changes in nutritional habits were studied in Dutch adolescents from 12 to 17 years of age (131 girls and 102 boys). The dietary differences on schooldays and weekend days are reported.2. In girls only small changes in nutritional habits were seen as they grew older. In boys there was a gradual increase in food intake with age.3. Overall, higher nutrient intakes could be seen on weekend days. The energy intake on weekend days was consistently higher for girls and boys in all age-groups. The proportional intakes of fat and sugar were rather high, especially on weekend days. The alcohol consumption increased with age for girls as well as boys, and was for some individuals extremely high (boys) on weekend days.4. The observed levels of intake compared with the recommendations showed a rather low intake of polyunsaturated fatty acids, polysaccharides and iron.

The Mediterranean

Background: The cardioprotective effects of the Mediterranean diet have been well established in epidemiological studies. More recently, it has been shown to improve the cardiometabolic risk profile and endothelial function, as well as reduce markers of vascular inflammation, independent of weight loss. Since cardiovascular disease is the second cause of death in the Canadian and North American populations, randomized clinical trials evaluating the efficacy of the Mediterranean diet in high-risk primary and secondary prevention are warranted. In order to conduct such studies, validated dietary assessment methods specific to population and food habits are needed. Therefore, the aim of our study was to assess the reproducibility and the relative validity of a quantitative food frequency questionnaire (FFQ) to be used in clinical trials at the Montreal Heart Institute’s Prevention Center. Methods: Fifty (50) participants (54% (27 of 50) women) aged 19 to 86 years with and without coronary disease were recruited, and randomized in 3 groups in a crossover design where the sequence of administration of questionnaires differed in each group. The FFQ includes 157 food items and was designed to measure food intake over one month. It was administered twice 3 to 5 weeks apart to assess reproducibility and was compared to a 12-day dietary record carried out over a 1-month period to assess validity. Participants were asked not to modify their diet for the duration of the study. FFQs were self-administered and reviewed by a registered dietician. All questionnaires were analyzed using The Food Processor software. Results: Reproducibility (n = 49) assessed by the intraclass correlation coefficient (ICC) revealed good (ICC > 0.5) to very good (ICC > 0.7) correlations for energy and all nutrients (except vitamin A) with ICCs ranging from 0.48 (95% confidence interval (CI), 0.23 to 0.67) for vitamin A to 0.91 (95% CI, 0.85 to 0.95) for alcohol (mean 0.68). Preliminary results for validity (n = 15) revealed very good significant correlations for EPA, DHA, selenium and alcohol and good significant correlation for energy, total fat, saturated fatty acids, monounsaturated fatty acids, oleic acid, linolenic acid, trans fat, vitamin B3, vitamin D, iron and magnesium. Conclusions: Our FFQ demonstrates good to very good reproducibility. Furthermore, the FFQ appears valid for evaluating adherence to a Mediterranean diet, notably because it provides very good estimates of marine omega-3 fatty acid (EPA, DHA) intake. These results support the eventual use of our FFQ in clinical trials on the Mediterranean diet. Complete sample analysis will be available in March 2014.

Polyphenol Intake

Abstract We examine the validity and reproducibility of a food frequency questionnaire (FFQ) in a subsample of participants in the Japan Public Health Center-based Prospective Cohort Study using a database of polyphenol-containing foods commonly consumed in the Japanese population. Participants of the validation study were recruited from two different cohorts. In Cohort I, 215 participants completed a 28-d dietary record (DR) and the FFQ, and in Cohort II, 350 participants completed DRs and the FFQ. The total polyphenol intake estimated from the 28-d DR and FFQ were log-transformed and adjusted for energy intake by the residual method. Spearman correlation coefficients (CCs) between estimates from the FFQ and 28-d DR as well as two FFQs administered at a 1-year interval were computed. Median intakes of dietary polyphenols calculated from the DRs were 1172 mg/d for men and 1024 mg/d for women in Cohort I, and 1061 mg/d for men and 942 mg/d for women in Cohort II. The de-attenuated CCs for polyphenol intake between the DR and FFQ were 0⋅47 for men and 0⋅37 for women in Cohort I and 0⋅44 for men and 0⋅50 for women in Cohort II. Non-alcoholic beverages were the main contributor to total polyphenol intake in both men and women, accounting for 50 % of total polyphenol intake regardless of cohort and gender, followed by alcoholic beverages and seasoning and spices in men, and seasoning and spices, fruits and other vegetables in women. The present study showed that this FFQ had moderate validity and reproducibility and is suitable for use in future epidemiological studies.

Abstract Background The dietary nutritional status of the lactating mothers is related to maternal health and has a significant impact on the growth and development of infants through the secretion of breast milk. The food frequency questionnaire (FFQ) is the most cost-effective dietary assessment method that can help obtain information on the usual dietary pattern of participants. Until now, the FFQs have been used for different populations in China, but there are few FFQs available for the lactating mothers. We aimed to develop a semi-quantitative, 156-item FFQ for the Chinese lactating mothers, and evaluate its reproducibility and relative validity. Methods A total of 112 lactating mothers completed two FFQs and one 3-d dietary record (3DR). The first FFQ (FFQ1) was conducted during postpartum at 60–65 days and the second FFQ (FFQ2) during subsequent follow-up at 5 weeks. The 3DR was completed with portion sizes assessed using photographs taken by the respondent before and after eating (instant photography) 1 week after FFQ1. Results For reproducibility, the Spearman’s correlation coefficients for food ranged from 0.34 to 0.68, and for nutrients from 0.25 to 0.61. Meanwhile, the intra-class correlation coefficients for food ranged from 0.48 to 0.87, and for nutrients from 0.27 to 0.70. For relative validity, the Spearman’s correlation coefficients for food ranged from 0.32 to 0.56, and for nutrients from 0.23 to 0.72. The energy-adjusted coefficients for food ranged from 0.26 to 0.55, and for nutrients from 0.22 to 0.47. Moreover, the de-attenuation coefficients for food ranged from 0.34 to 0.67, and for nutrients from 0.28 to 0.77. The Bland-Altman plots also showed reasonably acceptable agreement between the two methods. Conclusions This FFQ is a reasonably reproducible and a relative valid tool for assessing dietary intake of the Chinese lactating mothers.
