Characteristics of Under- and Over-Reporters of Energy Intake among Young Japanese Women
Journal of Nutritional Science and Vitaminology, 2012
Evidence on factors associated with misreporting of energy intake is limited, particularly in non-Western populations. We examined the characteristics of under-and over-reporters of energy intake in young Japanese women. Subjects were 3,956 female Japanese dietetic students aged 18-20 y (mean body mass index: 20.9 kg/m 2). Energy intake was assessed using a comprehensive self-administered diet history questionnaire. Estimated energy requirement was calculated based on self-reported information on age, body height and weight, and physical activity with the use of an equation from the US Dietary Reference Intakes. Under-, acceptable, and over-reporters of energy intake were identifi ed based on the ratio of energy intake to estimated energy requirement, according to whether the individual's ratio was below, within, or above the 95% confi dence limits of the expected ratio of 1.0 (Ͻ0.70, 0.70-1.30, and Ͼ1.30, respectively). Risk of being an under-or over-reporter of energy intake compared to an acceptable reporter was analyzed using multiple logistic regression. The percentage of under-, acceptable, and over-reporters of energy intake was 18.4, 73.1, and 8.4%, respectively. Under-reporting was associated with overweight or obesity, perception that one's own weight was too heavy or light, lower dietary consciousness, active lifestyle, living without family, and living in a city (compared with a metropolitan area). Over-reporting was associated with sedentary lifestyle only. This study of lean young Japanese women showed that energy intake misreporting, particularly under-reporting, was common and differential among populations. Particularly, perceived weight status was associated with under-reporting of energy intake, independent of actual weight status.

The influence of age and body mass index on relative accuracy of energy intake among Japanese adults
Public Health Nutrition, 2006
ObjectiveTo examine relationships between the ratio of energy intake to basal metabolic rate (EI/BMR) and age and body mass index (BMI) among Japanese adults.DesignEnergy intake was assessed by 4-day semi-weighed diet records in each of four seasons (16 days in total). The EI/BMR ratio was calculated from reported energy intake and estimated basal metabolic rate as an indicator of reporting accuracy.SettingResidents in three areas in Japan, namely Osaka (urban), Nagano (rural inland) and Tottori (rural coastal).SubjectsOne hundred and eighty-three healthy Japanese men and women aged ≥30 years.ResultsThe oldest age group (≥60 years) had higher EI/BMR values than the youngest age group (30–39 years) in both sexes (1.74 vs. 1.37 for men; 1.65 vs. 1.43 for women). In multiple regression analyses, age correlated positively (partial correlation coefficient, β = 0.012, P < 0.001 for men; β = 0.011, P < 0.001 for women) and BMI correlated negatively (β = −0.031, P < 0.001 for men; ...

Background: This paper investigated the relationship between body mass index (BMI) and total energy intake as well as intake of three major nutrients in representative Japanese populations enrolled in the National Nutrition Surveys of Japan in 1980 and 1990. Methods: A total of 10 422 participants (4585 men and 5837 women) and 8342 participants (3488 men and 4854 women) aged 30 or older from 300 randomly selected districts participated in the National Survey of Circulatory Disorders and the National Nutrition Survey in Japan in 1980 and 1990, respectively. The nutrition surveys were performed with weighing record method for three consecutive days to each household. Individually estimated total energy intake and intakes of three major nutrients (carbohydrate, protein, and fat) were compared by the categories of BMI and by 10-year age groups. Results: In men, total energy intake (kcal/day), intakes of three major nutrients (g/day) and energy intake ratio from protein and fat (%) increased as BMI increased in each age group, whereas energy intake ratio from carbohydrate (%) decreased. In women, total energy intake, intakes of three major nutrients, and energy intake ratio from protein increased as BMI increased. Energy intake ratio from carbohydrate and fat decreased as BMI increased in women in 1990. When participants were categorized into quartiles according to total energy intake in each sex group, BMI increased as total energy intake increased in men in both 1980 and 1990. Conclusions: A positive relationship was observed between body mass index and total energy intake in Japanese men. The relationship was weaker in Japanese women.

The associations of dietary energy density with dietary intake and obesity have been largely unexplored in non-Western populations. The present cross-sectional study examined the associations using data from the 2012 National Health and Nutrition Survey, Japan. Dietary intake was assessed using a 1-d semi-weighed dietary record in 15 618 Japanese adults aged ≥20 years. Mean dietary energy density (calculated on the basis of foods only) was 5·98 (sd 1·20) kJ/g in men and 5·72 (sd 1·16) kJ/g in women. Dietary energy density was positively associated with intakes of bread, noodles (only men), meat, fats and oils, and sugar and confectionery but inversely with intakes of white rice (only men), potatoes, pulses, vegetables, fruits, and fish and shellfish. For nutrient intake, dietary energy density was positively associated with total fat and SFA but inversely associated with all other nutrients examined such as protein, carbohydrate, alcohol (only women), dietary fibre, and several vita...

To determine the association between geriatric disorders and dietary intake, validation of a food frequency questionnaire (FFQ) for elderly individuals is needed. We compared energy and nutrient intakes derived from dietary records (DR) and FFQ in an elderly population and compared the data against results from middle-aged individuals (30–68 years) from a previous study. Current participants included 65 women and 78 men (65–88 years) who completed FFQ and 7-day DR in a subpopulation of the Kyoto-Kameoka study. Our FFQ was created for middle-aged individuals. To validate the FFQ, we investigated equivalent precision by comparing the correlation coefficients between the present and previous study. Median correlations for energy and nutrient intake between the DR and FFQ in the current and previous studies were 0.24 and 0.30 (p = 0.329) in women and 0.24 and 0.28 (p = 0.399) in men, respectively. The median ratio of FFQ to DR for these intakes were also similar. The accuracy and precis...

Hidden obese people" have a high body fat percentage (BFP) despite having a normal BMI (18.5 <BMI ≦ 25.0 BFP ≧30) due to an excessive accumulation of visceral fat, which increases their risk of lifestyle-related diseases. We aimed to identify factors that contribute to hidden obesity among Japanese female students at the Nutritionist Training Facility University using their anthropomorphic measurements, lifestyle characteristics and nutritional intake. Characteristics of participants with hidden obesity physique (18.5 <BMI ≦ 25.0 and BFP >30%) (n = 160) and standard physique (18.5 <BMI ≦ 25.0 and BFP <30%) (n = 376) were compared using Student's t-test or Welch's t-test. The participants with hidden obesity physique have lower intake of energy (p = 0.044) and fat (p = 0.036) and a higher intake of carbohydrates (p = 0.023), cereals (p = 0.009) and sugary beverages (p = 0.020). This study suggests that a reduction in carbohydrate-dense foods is effective in preventing hidden obesity.

Calculation of intake of nutrients We computed the average daily consumption of energy and selected nutrients using information from the FFQ and lifestyle questionnaire, including consumption of alcohol. According to the regression analysis, selected nutrients were adopted as dependent parameters and foods/food groups consumed, intake frequency, portion size (in grams) from our database, 5, 8 or typical/standard values from the literature, nutrient contents per 100 grams of foods/food groups listed in the respective composition tables or of the model recipes were assumed to be independent variables. 9-13 With the WDRs, we calculated mean daily intakes of selected nutrients by multiplying the consumption of foods/food groups (in grams) and nutrient contents per 100 grams of foods as listed in the composition tables or model recipes. Validation First, we compared mean daily intakes of energy and 26 selected nutrients gauged with the FFQ against those with the 3d-WDRs. Differences in means and ratios were computed with the FFQ vs. 3d-WDRs values, and examined by t-test using Excel ® and the SPSS ®-10.0 software package. Second, we calculated crude Pearson's correlation coefficients (CCs), log-transformed Pearson's CCs, log-transformed and energy-adjusted Pearson's CCs, and de-attenuated, log-transformed and energy-adjusted Pearson's CCs between intakes of selected nutrients based on the FFQ and 3d-WDRs. Energy adjustment was executed using regression models. 14 De-attenuated Pearson's CCs were computed by partitioning within-and inter-individual variations by one way of analysis of variance according to the formula described elsewhere. 3, 15-17 Crude Spearman's rank CCs and energy-adjusted Spearman's rank CCs were also calculated. 18,19 Statistical significance was verified with the 95% confidence interval. Third, after categorizing daily intakes of nutrients quantified with the FFQ and 3d-WDRs into quartiles, we computed percentages of exact agreement, agreement within adjacent categories, and disagreement. Ethical issues Our study protocol was reviewed and approved by the Internal Review Board at Nagoya City University Graduate School of Medical Sciences. Written informed consent was obtained from each participant. Profile of study subjects The mean ages standard deviations (SDs) (minimum-maximum) were 51.7 years 8.9 (30-68) for males, and 49.6 years 8.8 (30-68) for females. The values for height, weight and body mass index (kg/m 2) were 169.6 cm 6.

ObjectiveLittle is known about the relationship of monetary diet costs to dietary intake and obesity, particularly in non-Western populations. This study examined monetary cost of dietary energy in relation to diet quality and body mass index (BMI) among young Japanese women.DesignDietary intake was assessed by a validated, self-administered, diet history questionnaire. Diet costs were estimated using retail food prices. Monetary cost of dietary energy (Japanese yen 1000 kcal−1) was then calculated. BMI was computed from self-reported body weight and height.SubjectsA total of 3931 female Japanese dietetic students aged 18–20 years.ResultsMonetary cost of dietary energy was positively associated with intakes of fruits, vegetables, fish and shellfish, and pulses; however, higher monetary cost of dietary energy was also associated with higher consumption of fat and oil, meat and energy-containing beverages, and lower consumption of cereals (rice, bread and noodles) (all P for trend <...

Desire for weight change and level of dietary consciousness may severely bias reported food intake in dietary surveys. We evaluated to what degree under-and overreporting of energy intake (EI) was related to lifestyle, sociodemographic variables, and attitudes about body weight and diet in a nationwide dietary survey. Data were gathered by a self-administered quantitative food-frequency questionnaire distributed to a representative sample of men and women aged 16-79 y in Norway, of whom 3144 subjects (63%) responded. Reported EI was related to estimated basal metabolic rate (BMR) based on self-reported body weight, age, and sex. An EI:BMR < 1.35 was considered to represent underreporting and an EI:BMR ≥ 2.4 as overreporting of EI. Fewer men than women underreported EI (38% compared with 45%). The fraction of overreporters did not differ significantly between sexes (7% of the men compared with 5% of the women). A large proportion of underreporters was obese (9%) and wanted to reduce their weight (41%). Few overreporters were obese and 12% wanted to increase their weight. Underreporters consumed fewer foods rich in fat and sugar than did the other subjects. Multiple regression analysis showed that desire for weight change and physical activity score were significantly correlated with both EI and EI:BMR when adjusted for sociodemographic and lifestyle variables. Our findings indicated that attitudes about one's own body weight influenced reported EI. These attitudes are important in the interpretation of dietary data because many of the subjects (> 30%) wanted to change their body weight. Am J Clin Nutr 1998;68:266-74.
