Introduction: Spinocerebellar ataxia type 2 (SCA2) is a neurodegenerative and inherited disorder. No study has been conducted to characterize nutritional intake in Cuban SCA2 patients. Objective: To test the reproducibility and reliability of the 24-hour dietary recall method for the assessment of nutritional intake in Cuban patients with SCA2, as well as to obtain a preliminary characterization of nutritional intake in these patients. Material and Methods: A cross-sectional test-retest study was conducted on 35 SCA2 patients. The 24-hour dietary recall questionnaire in the CERES+ system was used. Results: Highly significant correlations between the first and second measurements were obtained for energy and nutrients intake, and according to food groups. Intraclass correlation coefficients higher than 0.75 were obtained for energy and most of the nutrients and according to food groups. Significant differences were obtained between male and female patients in terms of proteins, carbohydrates, cobalamin, iron, sodium, and zinc intake. An increase in sodium intake and a decrease in folic acid and copper intake were obtained. SCA2 patients showed increased sodium intake, and decreased folic acid and copper intake relative to nutritional intake recommendations for the Cuban population. Conclusions: The 24-hour recall dietary questionnaire is reproducible and reliable for the assessment of nutritional intake in SCA2 patients. Preliminary characterization of nutritional intake in SCA2 patients was obtained(AU)

Study On the Validity Of Instant Photography Method For Dietary Assessment In Undergraduate College Students

Background A healthy diet in a college student life is critical to ensure their normal growth, study anddevelopment.Aim In order to accurately assess the dietary pattern of college students and guide it, our study aims to evaluatethe validity of instant photography as an alternative dietary assessment method in college students.Methods Nine participants were enrolled and given a presentation on dietary assessment methods, includingweighing, 24-hour recall, and instant photography. The participants took pictures of their foods from three anglesbefore and after eating for constant seven days, foods weighing was completed by others. Then, the participantsrecalled the foods’ weights after 24 hours. Two trained observers estimated food weight from the digital images(n = 285) gathered at the end of the study with the aid of Chinese food atlas reference.Results Instant photograph showed significant correlation with weighing method on food weights of grains,tubers, vegetables, fruits, meat and eggs (all P ≤ 0.01). 24-hour method had similar correlation with weighingmethod on food weights except fruits. Compared with 24-hour recall, instant photograph displayedunderestimation on weights of grains, tubers, vegetables, and meat. However, instant photograph had moreaccurate estimations on weights of fruits and egg. Furthermore, compared with nutrients data from weighingmethod, both instant photography and 24-hour recall methods showed promising estimations on the amounts ofenergy, protein, fat, carbohydrate, vitamin A, vitamin C, vitamin E, calcium, iron and zinc (all P < 0.001). Comparedwith 24-hour recall, instant photograph displayed underestimation on the amounts of energy, protein, fat,carbohydrate, vitamin A, vitamin C, vitamin E, zinc. However, instant photograph had a more accurate estimationon calcium.

Accuracy of 24-hour Diet Recalls for Estimating Energy Intake in Elderly Men using the Doubly Labeled Water Method / 대한지역사회영양학회지

OBJECTIVES: This study assessed the accuracy of the 24-hour diet recall method for estimating the energy intake of elderly men using the doubly labeled water as a reference method. METHODS: Seventeen subjects (mean age 72.5 ± 3.9 years), who maintained the same body weight during the two weeks study period, were included in this study. Three 24-hour diet recalls (two weekdays and one weekend) were obtained over a 14 day period to estimate the mean energy intake. The total energy expenditure was measured over the same 14 days using the doubly labeled water method. The total energy intake and total energy expenditure were compared by paired t-test. RESULTS: The total energy intake from the 24-hour diet recalls method was 2536.7 ± 350.6 kcal/day, and the total energy expenditure from the doubly labeled water method was 2659.8 ± 306.8 kcal/day. The total energy intake was slightly under-reported by −123.2 ± 260.8 kcal/day (−4.4%). On the other hand, no significant difference was observed between the total energy intake and total energy expenditure of the subjects (p=0.069). The percentage of accurate predictions was 64.7%. The correlation between the total energy intake and total energy expenditure was statistically significant (r=0.697, p < 0.005). CONCLUSIONS: The present study supports the use of the 24-hour diet recall method to estimate the mean energy intake in elderly men group. More studies are needed to assess the validity of 24-hour diet recall method in other population groups, including elderly women, adults and children.

Development and User Satisfaction of a Mobile Phone Application for Image-based Dietary Assessment / 대한지역사회영양학회지

OBJECTIVES: The objective of this study was to develop mobile phone application for image-based dietary assessment and evaluate satisfaction regarding respondent's use of the mobile phone application. METHODS: We developed a mobile phone application to assess dietary intakes using 24 hour dietary recall. After initial development, application was reviewed by ten adults and revised based on their comments. We recruited 192 volunteers (92 males, 100 females) to use the mobile phone application and to respond to a satisfaction survey. Participants were instructed to use the mobile phone application with fiducial marker five centimeter in width, length and two centimeter height at each eating occasion during designated 4 days, capturing 45° angle and 90° angle images of all food and beverage items before and after consumption. After using the mobile phone application for 4 days, participants were asked to complete an online questionnaire on the satisfaction of the mobile phone app. User satisfaction items composed of 12 questions of application user interface, 8 questions of emotional response, 9 questions of eating behavior in 5 likert scale. Participants were also asked to provide additional open-ended comments on the use of mobile phone application. Statistical analysis was performed by using the SPSS 23.0 (Statistical Package for the Social Science). RESULTS: The average user interface score was 2.82 ± 1.08, which was close to the ‘normal’ response. Responses for emotion and eating behavior also were borderline to the ‘normal’. CONCLUSIONS: This study found that the mobile phone application using 24-hour recall was acceptable to be used to assess dietary intakes for several days. However, there should be a need for such technology to be user-oriented instead of researcher-oriented. Easy and cost-effective new technology is needed for estimating the amounts of food eaten automatically when the photos are taken.

Carbohydrate Intake Exhibited a Positive Association with the Risk of Metabolic Syndrome in Both Semi-Quantitative Food Frequency Questionnaires and 24-Hour Recall in Women

We compared the usual nutrient intake in both the semi-quantitative food frequency questionnaire (SQFFQ) and 24-hour recall methods and determined the association between metabolic syndrome (MetS) risk and nutrient intake calculated by both methods in Korea National Health and Nutrition Examination Survey (KNHANES; 2012–2014) data. Adjusted odds ratios for MetS were calculated according to the intake of macronutrients, measured by the 2 methods in 10,286 adults, while controlling for covariates associated with MetS. Fat and carbohydrate intake (energy percent) calculated by 24-hour recall and SQFFQ was significantly different between the MetS and non-MetS groups, particularly in women. The differences in other nutrient intakes determined by both methods were mainly non-significant. The correlation coefficients between the 2 methods were about 0.4 for most nutrients except total vitamin A and iron (Fe). Energy intake according to gender and MetS presence was similar between the 2 methods. Carbohydrate intake exhibited a positive association with the MetS risk, while fat intake showed a negative association in both methods. The association exhibited a gender interaction with carbohydrate and fat intake calculated by 24-hour recall: women exhibited a significant association. However, for the SQFFQ a gender interaction was evident only for carbohydrate intake. In diet quality index of SQFFQ the adequacy of vegetables and total fat intake was higher in the non-MetS than the MetS. In conclusion, the MetS prevalence exhibited a positive association with carbohydrate intake only in women, as assessed by 24-hour recall and SQFFQ. The SQFFQ can be used to assess the association between usual food intake and MetS risk in large population studies.

A Study on Application of Food Photographs for Estimating Individuals' Dietary Intake / 대한지역사회영양학회지

This study was performed to investigate the validity of food photographs for estimating individuals' dietary intakes and compare it with other dietary assessment methods. Subjects were 7 professors, 2 researchers, 12 dietitian and 16 graduate students majoring in food and nutrition. Among the subjects, 20 subjects had research experiences in the dietary intake survey more than one year while 17 had not. Each subject estimated 50 food portions displayed in computer monitor by comparing with standard food photographs, which were weighed portions of 28 foods from typical Korean diet. No significant differences between the estimated value and the weighed value of 17 (34%) food portions were shown in research-experienced group and those of 14 (28%) food portions were shown in no-researchexperienced group. 24-hour recall was the most frequently-used method for dietary assessment followed by in the order of food frequency questionnaire, dietary record, diet history and weighing method. After estimating food portions by photographs, 30 subjects (81%) were willing to use the method for dietary assessment because of its convenience and easy communication between researcher and subject. This study suggests that digital photography method would be a useful and convenient new instrument for estimating individuals' dietary intake. However, it is necessary to create standard database for food portions and carry out systematic education for food estimation in order to apply this method in the fields.

Analysis of Foods and Nutrients Intake Obtained at the Final Probing Step in 24-hour Recall Method

This study was conducted to examine the usefulness of adding final probing step (step3) in dietary assessment by 24-hour recall method among Korean adults. One-hundred fifty five adults (37 males and 118 females) above 30 years of age who visited hospitals for health examination were recruited at three hospitals in Korea. One day dietary intake was obtained using 24-hour recall method from each subject. Dietary interview was conducted in 3 steps, (1) quick list of foods eaten during the previous day, (2) detailed information of all the foods eaten, (3) the final probing for any items forgotten. Items added at the step3 were identified and contributions of energy and nutrient intakes were calculated. The average duration of interview was 10.5 min, and time spent for each step was 4.12 minute for step 1, 5.62 minute for step 2, and 38 second for step 3. The average number of dishes reported by the subjects added at the step 3 was 2.2. (Males = 2.6, Females = 1.6) Frequently reported dishes in the step 3 were Beverage, Tea, alcohol (37.1%) and Fruits (31.8%). From mean total energy intake of 1,589 kcal (Men = 1,846 kcal, Women = 1,509 kcal), 179 kcal (11.3%) was added at the step 3. In the step 3, nutrient intakes increased significantly except retinol in total subjects and except retinol and cholesterol in males but all nutrients increased significantly in females. The final probing step can add significant information on intakes of foods and many nutrients with only about 38 seconds of interview time. Confirmation of the results with larger samples of different age groups is needed.

Effect of Nutritional Education and Exercise Intervention on Reducing and Maintaining Weight in Obese Women / 대한지역사회영양학회지

This study was performed to investigate the effectiveness of nutritional education and exercise intervention on reduction and maintenance of weight. The subjects were 24 obese women whose body mass index (BMI) was over 25 kg/m(2). Nutritional education was performed once a week and swimming was done three times a week throughout this 12 week program. The subjects were recalled 1 month after the program was complete. Nutrient intakes were assessed by 24 hour recall method. Also food habits, dietary behaviors and nutritional knowledge were investigated by self-administered questionnaires before and after the weight control program and one month after completing the program. Height, weight, body composition and blood levels were measured before and after the weight control program and one month after completing the program. During the 12 weeks of the weight control program, body weight significantly decreased from an average of 69.7 kg to 65.8 kg and to 65.1kg after one month (p < 0.05). Body fat and BMI also significantly decreased (p < 0.01). Cholesterol and blood sugar levels decreased after 12 weeks and increased one month after completing the program. After taking nutritional education, the nutritional knowledge scores increased. Calcium intake significantly increased after completing the education and one month after completing the program (p < 0.01). Iron intake significantly decreased from an average of 12.1 g to 11.3 g after completing the program and increased to 15.5 g one month after completing the progrom (p < 0.001). We concluded that our nutritional education and exercise program was effective for reducing and maintaining weight.

Dietary Underreporting from the 2001 Korean National Health and Nutrition Survey

BACKGROUND: Underreporting in self-reported dietary survey is a potential source of bias in nutritional epidemiology. We assessed if dietary underreporting existed in the 2001 Korean National Health and Nutrition Survey (KNHANS) and evaluated the health related factors and nutrients associated with dietary underreporting. METHODS: The subjects were 2,552 men and 3,335 women, 18 years of age or older, with a complete 24 hour recall and physical examination data including height and weight. Basal metabolic rate (BMR) was calculated from weight and height using WHO equations. Questionnaire to assess daily physical activity and regular exercise was done. EI/BMR ratio was used to evaluate dietary underreporting. RESULTS: The mean EI/BMR ratio of Korean men and women were 1.43+/-0.56 and 1.41+/-0.57, respectively. Among the total, 20.6% of men and 22.8% of women reported their energy intake lower than their BMR. Age was negatively related with EI/BMR ratio only in women (P<0.001). Body mass index, education level, and household income were negatively and daily physical activity was positively associated with the EI/BMR ratio in both sexes. Lower EI/BMR ratio was significantly associated with lower reported fat energy density (% of energy intake) and higher reported carbohydrate and protein energy densities. The EI/BMR ratio was related negatively with nutrient energy densities of Vitamin C, Calcium, and Iron. CONCLUSION: We could confirm selective dietary underreporting in the 2001 KNHNS. Caution should be paid on the interpretation of the nutrition survey data and efforts should be exercised to reduce dietary underreporting at data collection stages.

Software for Nutritional Assessment Using a Semi-Quantitative Food Frequency Questionnaire and the 24-hour Recall Method / 대한지역사회영양학회지

The purpose of this study was to develop a computer software program for nutritional assessment using a Semi-Quantitative Food Frequency Questionnaire (SQFFQs) and the 24-hour Recall Method. The software for the SQFFQ was divided into input, output, and database. For dietary analyses, recipe and food databases were used. The recipe database included 25 items and the food database was divided into 18 food groups. The food database was composed of 19 general nutrient items, 33 fatty acids, and 18 amino acids. The software developed in this study can be summarized as follows: 1) input items related to the individual's ages information, lifestyle, biological values, and dietary habits; 2) individualized data in percent of the Korean RDA, the energy ratios of carbohydrates, proteins and fats, the ratio of animal to plant source intakes, and the distribution of food group intakes; 3) Statistical data on the individual's information, lifestyle, biological values, and dietary intakes including the frequency of intake of cooked foods, the amounts of food, and the number of food groups, and nutrients. In the 24-hour Recall Method, the input and output consisted of the individual's information and cooked dish intakes. The individual's report included the amounts of nutrient intake according to number of meal and days, in comparison to the Korean RDA, the energy ratio for carbohydrates, proteins and fats, the ratio of animal to plant source intakes, and the distribution of food group intakes. The statistical report presented the number of food groups and foods, and the nutrient intakes. To evaluate the validity of the SQFFQ, the Spearman Rank Order Correlation and kappa values were used. As a result, correlation coefficients comparing the 24-hour Recall Method appeared to be more than 0.5, except for vitamin B1, B2, niacin, and vitamin E. The kappa values for energy and carbohydrate intakes were both 0.7, and protein, fat, vitamin C, folate, Ca, and iron intakes ranged from 0.3 to 0.7.

The Analysis of the Difference between Interviewers and the Days of the Week using the 24-Hour Dietary Recall Method

The purpose of the study is to evaluate the differential effects caused by the interviewers and the days of the week using the 24-hour dietary recall method on the dietary evaluation of nutrient intakes. Thirteen subjects were interviewed by three trained interviewers on a Monday, Wednesday, and Friday. The consumption of nutrients by the subjects during each day was assessed. The average intake of nutrients was found to be sufficient except in calcium, iron, and vitamin A. there was a significant difference between the food intake on the weekdays and that o the weekend. However, the were no significant differences between the interviewers assessments on the intake of nutrients consumed by the subjects. The standardization of the portion size, interview skill and experience may be a few of the reasons explaining the elimination of the potential error created by variations among the interviewers. This study suggests that repeated 24-hour recalls during weekdays and weekends may be a better method for estimating the nutrients consumed by the subjects.
