Validity and Acceptability of Image-based Food Record in Assessing Nutrient Intake among selected Malaysian Undergraduates

@#Introduction: Recognising the limitations of present dietary assessments method, recent attention had been drawn to image-based food record (IBFR) to assess dietary intake of the population. Thus, the present study aimed to compare nutrient intake assessed using IBFR with 24-hour diet recall (24DR) among nutrition and dietetics student. Method: There were 46 nutrition and dietetic undergraduates participated in the study, and information on the socio-demographic background and acceptability toward IBFR were obtained. Respondents were trained to complete one-day IBFR, and they were interviewed by researchers on the following day for their 24DR. Result: The mean age of respondents was 21.4±1.7 years old. The present study revealed that there were significantly higher protein and beta-carotene, but lower vitamin C reported by IBFR compared to 24DR. Medium to strong correlations were found between IBFR and 24DR for energy and nutrients intakes. The Bland-Altman analysis demonstrated a good level of agreement between IBFR and 24DR for energy and macronutrients (carbohydrates, protein and fat), respectively. The mean differences between IBFR and 24DR were -36 kcal for total daily energy intake, while mean differences of -12.24g, 0.79g, and 1.52g were reported for carbohydrates protein, and fat, respectively. Moderate level of agreement toward acceptability was demonstrated, and most of them (67.4%) preferred IBFR method. Conclusion: The present study revealed that IBFR showed a good level of agreement with 24DR in assessing nutrient intake. However, more extensive works should be considered to improve IBFR in assessing the energy and nutrients intake for the general population.

Usability of a smartphone food picture app for assisting 24-hour dietary recall: a pilot study

BACKGROUND/OBJECTIVES: The Recaller app was developed to help individuals record their food intakes. This pilot study evaluated the usability of this new food picture application (app), which operates on a smartphone with an embedded camera and Internet capability. SUBJECTS/METHODS: Adults aged 19 to 28 years (23 males and 22 females) were assigned to use the Recaller app on six designated, nonconsecutive days in order to capture an image of each meal and snack before and after eating. The images were automatically time-stamped and uploaded by the app to the Recaller website. A trained nutritionist administered a 24-hour dietary recall interview 1 day after food images were taken. Participants' opinions of the Recaller app and its usability were determined by a follow-up survey. As an evaluation indicator of usability, the number of images taken was analyzed and multivariate Poisson regression used to model the factors determining the number of images sent. RESULTS: A total of 3,315 food images were uploaded throughout the study period. The median number of images taken per day was nine for males and 13 for females. The survey showed that the Recaller app was easy to use, and 50% of the participants would consider using the app daily. Predictors of a higher number of images were as follows: greater interval (hours) between the first and last food images sent, weekend, and female. CONCLUSIONS: The results of this pilot study provide valuable information for understanding the usability of the Recaller smartphone food picture app as well as other similarly designed apps. This study provides a model for assisting nutrition educators in their collection of food intake information by using tools available on smartphones. This innovative approach has the potential to improve recall of foods eaten and monitoring of dietary intake in nutritional studies.

A Short Questionnaire for Assessment of Dietary Vitamin D Intake.

Aims: Dietary vitamin D intake is difficult to assess as it is irregular. In Sweden, main sourcesare oily fish, fortified dairy products and margarines. This relative validation study intends to investigate the agreement in dietary vitamin D intake between a short vitamin D questionnaire and a four day food record. Study Design: A cross sectional study design was implemented. Place and Duration of Study: Department of Internal Medicine and Clinical Nutrition, Sahlgrenska Academy, University of Gothenburg. Assessments were conducted between January 2009 and December 2012. Methodology: Ninety-five female subjects (25-40 years old) performed a short vitamin D questionnaire (VDQ), covering the consumption of four foods with high vitamin D content (oily fish, milk, margarine and yoghurt/sour milk). They also performed a food record for four consecutive days in connection to the VDQ. Results: Median (quartile 1-quartile 3) dietary vitamin D intake was 4.7 (3.6-7.4) μg/day assessed by food record and 3.4 (2.3-4.6) μg/day assessed by VDQ. The dietary intakes of vitamin D correlated significantly between methods (P=.007). The amounts of vitamin D derived from each of the four foods did not differ between methods (P>.05). Conclusion: The short VDQ, including only four foods with high vitamin D content (oily fish, milk, margarine and yoghurt/sour milk), was able to capture the majority of the dietary vitamin D intake reported in food records. This relative validation study shows that the short questionnaire is a useful tool when assessing intake of major sources of dietary vitamin D on a group level.

Estimativa de ingestão protéica de pacientes em hemodiálise comparação entre registro alimentar e equivalente protéico deaparecimento de nitrogênio (pna) / Estimation of protein intake of hemodialysis patients comparison between food record and protein equivalent ofnitrogen appearance (pna)

Introdução: A avaliação do consumo alimentar, particularmente da ingestão de proteínas, constitui uma ferramenta importante na prevenção, tratamento emonitoramento da desnutrição nos pacientes em hemodiálise. Para tanto, os métodos mais comumente utilizados na prática clínica são o registro alimentar eo equivalente protéico do aparecimento de nitrogênio (PNA). Objetivo: Avaliar a concordância entre o registro alimentar e o PNA para a estimativa da ingestãoprotéica nos pacientes em hemodiálise. Casuística e Métodos: Foram estudados 39 pacientes (67% homens, 46,8±14,7anos, IMC 23,5±4,6kg/m2) emtratamento hemodialítico. Os critérios de exclusão foram presença de doenças catabólicas, função renal residual e uso de glucocorticóides. O registro alimentarfoi preenchido durante três dias e o PNA foi calculado conforme recomendado pelo NKF-DOQI. Resultados: A ingestão protéica obtida pelo registro alimentarfoi menor que aquela obtida pelo PNA (56,3±23,4 vs 67,9±23,9g/dia, respectivamente; P≤0,001). Os métodos apresentaram uma boa correlação (r=0,54;P<0,001), porém uma grande variabilidade individual foi observada (-51,7 a +28,5g/dia). A ingestão protéica obtida por ambos os métodos correlacionou-sepositivamente com o IMC (registro alimentar: r=0,41 e PNA r=0,80; P<0,05). A diferença entre os métodos (registro alimentar - PNA) correlacionou-senegativamente com o IMC (r=-0,49; P<0,01). A análise por subgrupos de IMC mostrou que o registro alimentar subestimava a ingestão protéica em relação aoPNA apenas nos pacientes com IMC≥25kg/m2. A regressão linear múltipla apontou o IMC≥25kg/m2 como único fator independentemente associado àsvariações entre os métodos. [β =-16,9 (-31,1 a -2,8); P=0,02] Conclusão: O método do registro alimentar exibiu valores menores de proteínas em relação aométodo do PNA nos pacientes em hemodiálise, sendo a condição de sobrepeso/obesidade um importante determinante destas variações.

Introduction: The assessment of food consumption, particularly of protein intake, constitutes an important tool in the prevention, treatment, and monitoringof malnutrition in hemodialysis patients. Food record and protein equivalent of nitrogen appearance (PNA) are the most commonly used methods for suchpurpose in the clinical practice. Aim: To evaluate the agreement between food record and PNA for the assessment of protein intake in hemodialysis patients.Subjects and Methods: Thirty-nine hemodialysis patients (67% male, 46.8 ± 14.7 years old, BMI 23.5 ± 4.6 kg/m2) were studied. The exclusion criteriawere catabolic illnesses, residual renal function and use of glucocorticoids. Food intake was recorded 3 days and PNA was calculated as proposed by theNKF-DOQI. Results: The protein intake assessed by food record was lower than that obtained by PNA (56.3 ± 23.4 vs 67.9 ± 23.9 g/day, respectively;P≤0.001). The methods were well correlated (r=0.54; P<0.001), however, a large individual variability was observed (-51.7 to +28.5 g/day). The protein intakeobtained by both methods correlated positively with BMI (food record: r=0.41 and PNA: r=0.80; P<0.05). The difference between the methods (food record,PNA) correlated negatively with BMI (r=-0.49; P<0.001). The analysis by subgroups of BMI showed that the food record method underestimated proteinintake in relation to PNA only in patients with BMI ≥25kg/m2. The multiple linear regression analysis pointed to BMI ≥25kg/m2 as a factor independentlyassociated with variations between the methods. Conclusion: The food record method showed lower values of protein in comparison with the PNA methodin hemodialysis patients, and overweight/obesity status was an important determinant of these variations.

The Physical Development and Dietary Intake for Korean Children and Adolescents: Food and Nutrient Intake

The aim of this study was to evaluate the food and nutrient intakes in 5th to 8th grade school boys and girls. A total of 1,333 students were recruited from 1 elementary and 1 middle school, both located in Seoul. The data on food and nutrients intake were collected by 3-day food record. The food intake was calculated as the percentage of total energy intake according to 21 food subgroups. The consumption of noodles, and meat's products (including ham and sausage) groups were higher in 7th and 8th grade than 5th and 6th grade. On the other hand consumption of vegetables and milk and its products groups were lower in 7th and 8th grade. As results, calcium, riboflavin, and vitamin C intakes were lower in 7th and 8th grade students. Dietary patterns by cluster analysis resulted in 77% of subjects with traditional pattern based rice and kimchi, and 23% with modified pattern. All students regardless of grades showed high fat intake, above 20 percent energy intake from fat, and high cholesterol intakes. In conclusion, there was significant difference between 5th and 6th grade primary school students and 7th and 8th junior school students regarding food and nutrient intakes. It should be necessary to provide proper nutrient education and monitoring in order to establish good dietary profile.
