Although many epidemiological studies have examined the association of dietary glycaemic index (GI) and glycaemic load (GL) with health outcomes, information on the reproducibility and relative validity of these variables estimated from dietary questionnaires is extremely limited. We examined the reproducibility and relative validity of dietary GI and GL assessed with a self-administered diet-history questionnaire (DHQ) in adult Japanese. A total of ninety-two Japanese women and ninety-two Japanese men aged 31–76 years completed the DHQ (assessing diet during the preceding month) and 4 d dietary records (DR) in each season over a 1-year period (DHQ1–4 and DR1–4, respectively) and the DHQ at 1 year after completing DHQ1 (DHQ5). We used intraclass correlations between DHQ1 and DHQ5 to assess reproducibility, and Pearson correlations between the mean of DR1–4 and mean of DHQ1–4 and between the mean of DR1–4 and DHQ1 to assess relative validity. Reproducibility correlations for dietary GI and GL were 0·57 and 0·69 among women and 0·65 and 0·58 among men, respectively. Validity correlations for dietary GI and GL assessed by DHQ1–4 were 0·72 and 0·66 among women and 0·65 and 0·71 among men, respectively. Corresponding correlations for DHQ1 were 0·53 and 0·58 among women and 0·57 and 0·60 among men, respectively. White rice was the major contributor to GI and GL in both methods (49–64 %). These data indicate reasonable reproducibility and relative validity of dietary GI and GL assessed by a DHQ for Japanese adults, whose dietary GI and GL are primarily determined by the GI of white rice.

Findings on dietary glycaemic index (GI) and glycaemic load (GL) as risk factors for type 2 diabetes have been controversial. We examined the associations of dietary GI and GL and the associations of substitution of lower-GI carbohydrates for higher-GI carbohydrates with diabetes risk in a cohort of Finnish men. The cohort consisted of 25 943 male smokers aged 50–69 years. Diet was assessed, at baseline, using a validated diet history questionnaire. During a 12-year follow-up, 1098 incident diabetes cases were identified from a national register. Cox proportional hazard modelling was used to estimate the risk of diabetes, and multivariate nutrient density models were used to examine the effects of substitution of different carbohydrates. Dietary GI and GL were not associated with diabetes risk; multivariate relative risk (RR) for highest v. lowest quintile for GI was 0·87 (95 % CI 0·71, 1·07) and for GL 0·88 (95 % CI 0·65, 1·17). Substitution of medium-GI carbohydrates for high-GI carbohydrates was inversely associated with diabetes risk (multivariate RR for highest v. lowest quintile 0·75, 95 % CI 0·59, 0·96), but substitution of low-GI carbohydrates for medium- or high-GI carbohydrates was not associated with the risk. In conclusion, dietary GI and GL were not associated with diabetes risk, and substitutions of lower-GI carbohydrates for higher-GI carbohydrates were not consistently associated with a lower diabetes risk. The associations of dietary GI and GL with diabetes risk should be interpreted by considering nutritional correlates, as foods may have different properties that affect risk.

AbstractObjectiveDietary questionnaires for assessing dietary intakes among populations of individuals aged 80 years or older (the very old) are very limited. We examined the relative validity of forty-three nutrients and twenty-seven food groups estimated by a brief-type self-administered diet history questionnaire (BDHQ) targeting very old Japanese, using semi-weighed dietary records (DR) as a reference.DesignBetween June and August 2012 and between June 2015 and February 2016, a three-day non-consecutive DR (at two-week intervals) and a BDHQ were completed.SettingTokyo, the capital prefecture of Japan.SubjectsEighty very old Japanese (thirty-six men and forty-four women) aged 82–94 years.ResultsThe median intakes of 40–70 % of the crude and energy-adjusted nutrients estimated by the BDHQ were significantly different from those estimated by the DR. The median Spearman’s correlation coefficient of nutrient intakes between the BDHQ and the DR was 0·39–0·46. About half (48–56 %) of the food groups were significantly different in terms of the median intakes estimated by the BDHQ and the DR in crude and energy-adjusted values. The median Spearman’s correlation coefficient between the BDHQ and the DR was 0·45–0·48.ConclusionsAcceptable Spearman’s correlations (≥0·3) were obtained for many dietary intakes among the very old Japanese population. The BDHQ is a good candidate for epidemiological studies among very old Japanese, although, for some nutrients and food groups, the difficulty of estimating accurate median intakes is one of the limitations for the tool. Further efforts to enhance the validity of the BDHQ for very old populations are needed.

AbstractObjectiveAlthough dietary pattern approaches derived from dietary assessment questionnaires are widely used, only a few studies in Western countries have reported the validity of this approach. We examined the relative validity of dietary patterns derived from a self-administered diet history questionnaire (DHQ) among Japanese adults.DesignThe DHQ, assessing diet during the preceding month, and 4 d dietary records (DR) were collected in each season over one year. To derive dietary patterns, 145 food items in the DHQ and 1259 in the DR were classified into thirty-three predefined food groups, and entered into a factor analysis.SettingThree areas in Japan; Osaka (urban), Nagano (rural inland) and Tottori (rural coastal).SubjectsA total of ninety-two Japanese women and ninety-two Japanese men aged 31–76 years.ResultsWe identified three dietary patterns (‘healthy’, ‘Western’ and ‘Japanese traditional’) in women and two (‘healthy’ and ‘Western’) in men, which showed a relatively similar direction and magnitude of factor loadings of food groups across the first and mean of four DHQ (DHQ1 and mDHQ, respectively) and 16 d DR. The Pearson correlation coefficients between DHQ1 and 16 d DR for the healthy, Western and Japanese traditional patterns in women were 0·57, 0·36 and 0·44, and for the healthy and Western patterns in men were 0·62 and 0·56, respectively. When mDHQ was examined, the correlation coefficients improved for women (0·45–0·69).ConclusionsDietary patterns derived from the DHQ could be used for epidemiological studies as surrogates of those derived from DR.

We examined the reproducibility and relative validity of two measures of overall diet quality, the Healthy Eating Index-2015 (HEI-2015) and Nutrient-Rich Food Index 9.3 (NRF9.3), as estimated by well-established self-administered dietary assessment questionnaires for the Japanese, namely the comprehensive diet history questionnaire (DHQ) and the brief diet history questionnaire (BDHQ). Diet was assessed separately by two DHQs and two BDHQs at a 1-year interval and by 16-day weighed dietary records (DRs) in 121 women and 121 men aged 31–81 years. HEI-2015 and NRF9.3 were calculated from each method. The reproducibility correlation for the two questionnaires (intraclass correlation) ranged from 0.53 (HEI-2015 from BDHQ in men) to 0.77 (NRF9.3 from BDHQ in women). The validity correlation between the first questionnaires and DR (Pearson correlation) ranged from 0.37 (NRF9.3 from BDHQ in men) to 0.61 (NRF9.3 from DHQ and BDHQ in women). Bland–Altman plots showed poor agreement between the DHQ or BDHQ and DR, as well as the presence of weak proportional bias. Overall, these data indicate reasonable reproducibility and ranking ability of the DHQ and BDHQ for assessing the HEI-2015 and NRF9.3 and support their usefulness in future epidemiological research on the overall effects of Japanese diets on various health outcomes.

AbstractObjectiveTo compare the relative validity of food group intakes derived from a comprehensive self-administered diet history questionnaire (DHQ) and a brief-type DHQ (BDHQ) developed for the assessment of Japanese diets during the previous month using semi-weighed dietary records (DR) as a reference method.DesignBetween November 2002 and September 2003, a 4 d DR (covering four non-consecutive days), a DHQ (150-item semi-quantitative questionnaire) and a BDHQ (fifty-eight-item fixed-portion-type questionnaire) were completed four times (once per season) at 3-month intervals.SettingThree areas in Japan: Osaka, Nagano and Tottori.SubjectsNinety-two Japanese women aged 31–69 years and ninety-two Japanese men aged 32–76 years.ResultsMedian food group intakes were estimated well for approximately half of the food groups. No statistically significant differences were noted between a 16 d DR and the first DHQ (DHQ1) or between the DR and the first BDHQ (BDHQ1) in fifteen (44 %) and fifteen (52 %) food items for women and in fourteen (41 %) and sixteen (55 %) food items for men, respectively, indicating that both questionnaires estimated median values reasonably well. Median Spearman's correlation coefficients with the DR were 0·43 (range: −0·09 to 0·77) for DHQ1 and 0·44 (range: 0·14 to 0·82) for BDHQ1 in women, with respective values of 0·44 (range: 0·08 to 0·87) and 0·48 (range: 0·22 to 0·83) in men, indicating reasonable ranking ability. Similar results were observed for mean values of the four DHQ and BDHQ.ConclusionsIn terms of food intake estimates, both the DHQ and the BDHQ showed reasonable validity.

Culinary herbs and spices contribute bioactives to the diet, which act to reduce systemic inflammation and associated disease. Investigating the health effects of herb/spice consumption is hampered, however, by a scarcity of dietary assessment tools designed to collect herb/spice data. The objective of this study was to determine the relative validity of an online 28-item herb/spices intake questionnaire (HSQ). In randomized order, 62 volunteers residing in Idaho, USA, completed the online Diet History Questionnaire III + the HSQ followed one week later by one of two comparative methods: 7-day food records or three telephone-administered 24-h dietary recalls. Relative validity of the HSQ was tested two ways: (1) by comparing herb/spice intakes between the HSQ and comparator, and (2) by determining the correlation between herb/spice data and Healthy Eating Index 2015 score. The HSQ and both comparators identified black pepper, cinnamon and garlic powder as the three most commonly used herbs/spices. The HSQ captured significantly higher measures of the number and amount of herbs/spices consumed than the comparators. The number of herbs/spices consumed was significantly directly correlated with diet quality for the HSQ. These results support the ability of the HSQ to record general herb/spice use, yet suggest that further validation testing is needed.

Our aim was to assess the validity of the brief-type self-administered diet history questionnaire (BDHQ15y) to estimate the protein intake in 248 Japanese secondary school students (mean age = 14.2 years), using urinary biomarkers as references. Participants provided three samples of overnight urine for measurement of urea nitrogen and creatinine levels, underwent anthropometric measurements, and answered the questionnaires. Additionally, 58 students provided 24-h urine specimens. A significant correlation was observed between excretion of urea nitrogen in overnight and 24-h urine specimens (ρ = 0.527; p < 0.001), with biases ≤5.8%. The mean daily protein intake estimated from urinary biomarkers was 76.4 ± 20.4 g/d in males and 65.4 ± 16.9 g/d in females, and the mean protein intake estimated from the BDHQ15y (PRTbdhq) was 89.3 ± 33.7 g/d in males and 79.6 ± 24.6 g/d in females. Crude and energy-adjusted coefficients of correlation between PRTbdhq and protein intake estimated from urinary biomarkers were 0.205 (p = 0.001; 0.247 for males and 0.124 for females), and 0.204 (p = 0.001; 0.302 for males and 0.109 for females), respectively. The BDHQ15y is a low-cost tool to assess protein intake of a large population, instead of a weakness of overestimation.

Background: According to recent national health surveys (2010-2013), diabetes mellitus (DM) is more prevalent in East Asian populations (11.6% in China, 11.3% in Japan) compared with Western populations (4.5% in UK and 8.3% in US), even though body weight and body mass index (BMI) are much lower in East Asian populations (mean ≈ 22-23 kg/m2 in China/Japan vs. ≈ 27-28 kg/m2 in UK/US, WHO 2008 report). Consumption of total available carbohydrate (CHO) (%kcal) in Eastern countries is higher than in Western countries. The patterns of CHO intake, dietary glycaemic Index (GI)/glycaemic Load (GL), may be important in accounting for these differences and their metabolic effects. Data on GI/GL of Asian foods are, however, limited. Objectives: To develop systematic methodology for assigning GI values to East Asian foods, and to identify East Asian foods contributing most to total GL, using data from the International Collaborative Study on Macro-/Micronutrients and Blood Pressure (INTERMAP). Methods: The INTERMAP Study is a cross-sectional epidemiologic investigation with standardized quality-controlled methods; it accrued four in-depth 24-hour dietary recalls, 2 timed 24-hour urine collections, 8 BP measurements and questionnaire data. National and International GI databases were used to develop a standardized algorithm for assigning GI values to the INTERMAP data on East Asian foods. “GL contribution of a food”, defined as the GI value of this food multiplied by total amount of available CHO contained in this food as consumed on average by all participants, was used to estimate total influence of each food on blood glucose, including absolute levels and relative percentages. Results: GI values of total of 2,928 East Asian individual food codes (2,030 Japanese food codes and 898 Chinese food codes) were assigned using this newly developed algorithm. Foods assigned with GI>0 using this algorithm contributed 92% (Japan) and 98% (China) of total CHO intake per day. Among Japanese foods, high GI foods were sweet red bean paste (Monaka, GI=91), rice cookie (GI=91), and rice cracker (GI=91). Among Chinese foods, high GI foods were flour and flour products (e.g., Mantou, steamed bread, fried dough sticks, and noodles, GI=88) and glutinous rice (GI=87). Foods contributing most to GL in Japan were white rice (54%), white bread (5%), sugar, syrup and preserves (3%); for Chinese foods: flour and flour products (25%), white rice (21%), and baked products (10%). Conclusion: With the algorithm we developed, it was feasible to assign GI values to East Asian foods. The composition of top GL contributors is different between China and Japan.

Abstract Food frequency questionnaires, the primary method of dietary assessment in large-scale nutritional epidemiologic studies, preclude an informed evaluation of the timing of dietary intake and meal-specific dietary intake. In this study, we developed the Meal-based Diet History Questionnaire (MDHQ), a self-administered questionnaire designed for estimating food and nutrient intakes for each meal type separately. The development was done based on a 16-day dietary record obtained from 242 Japanese adults. The MDHQ consisted of the three different parts, with a total of 196 items. Part 1 of the MDHQ asks about consumption frequency of generic food groups (n 24) for each meal type: breakfast, morning snack, lunch, afternoon snack, dinner, and night snack. Part 2 of the MDHQ asks about relative consumption frequency of sub-food groups within one of the generic food groups which are asked in Part 1. Combining information derived from Parts 1 and 2 enables to increase the number of foods we can estimate efficiently but within a limited number of questions. Part 3 of the MDHQ asks about general eating behaviors, which are intended to use in a variety of ways during dietary intake calculation. A series of calculation algorithms for food groups, energy, and nutrients were also prepared. Given that the MDHQ was empirically developed based on comprehensive information on actual food consumption, this innovative tool may be promising for future epidemiological research on meal patterns and time of day of dietary intake, or chrono-nutrition research. A rigorous evaluation of validity of the MDHQ is warranted.
