Having a system to measure food consumption is important to establish whether individual nutritional needs are being met in order to act quickly and to minimize the risk of undernutrition. Here, we tested a smartphone-based food consumption assessment system named FoodIntech. FoodIntech, which is based on AI using deep neural networks (DNN), automatically recognizes food items and dishes and calculates food leftovers using an image-based approach, i.e., it does not require human intervention to assess food consumption. This method uses one-input and one-output images by means of the detection and synchronization of a QRcode located on the meal tray. The DNN are then used to process the images and implement food detection, segmentation and recognition. Overall, 22,544 situations analyzed from 149 dishes were used to test the reliability of this method. The reliability of the AI results, based on the central intra-class correlation coefficient values, appeared to be excellent for 39% of the dishes (n = 58 dishes) and good for 19% (n = 28). The implementation of this method is an effective way to improve the recognition of dishes and it is possible, with a sufficient number of photos, to extend the capabilities of the tool to new dishes and foods.

Background: There are several methods for measuring edema of the hand. While the volumetric techniques, finger circumference measurement, and figure-of-eight techniques have undergone extensive psychometric testing, alternative methods of measuring hand size, such as circumferential finger size determination using a ring gauge (ring gauge method; RGM) and tape measurement of hand girth taken along the distal palmar crease (metacarpal head tape measure method; MHTM), have not. This study's aim is to examine the reliability and validity of the RGM and the MHTM. Methods: In this cross-sectional study, two examiners measured 22 hands in 22 patients with hand edema using the RGM and the MHTM 3 times each to determine intra- and inter-tester reliability. The validity of each method was established using the finger circumference measurement and figure-of-eight method, respectively. Results: The intra-class correlation coefficient (ICC) obtained for intra-tester reliability was 0.99–0.98 for both methods. ICCs for inter-tester reliability were 0.97–0.98 for the RGM and 0.98 for the MHTM. Pearson product-moment correlation values between the RGM and finger circumference measurement were 0.92–0.96, while those between the MHTM and figure-of-eight method were 0.84–0.90. Conclusions: The RGM and the MHTM are reliable and valid evaluation tools for the assessment of hand size.

Purpose: Study the repeatability of the evaluation of the perception of dyspnea using an inspiratory resistive loading system in healthy subjects. Methods: We designed a cross sectional study conducted in individuals aged 18 years and older. Perception of dyspnea was assessed using an inspiratory resistive load system. Dyspnea was assessed during ventilation at rest and at increasing resistive loads (0.6, 6.7, 15, 25, 46.7, 67, 78 and returning to 0.6 cm H2O/L/s). After breathing in at each level of resistive load for two minutes, the subject rated the dyspnea using the Borg scale. Subjects were tested twice (intervals from 2 to 7 days). Results: Testing included 16 Caucasian individuals (8 male and 8 female, mean age: 36 years). The median scores for dyspnea rating in the first test were 0 at resting ventilation and 0, 2, 3, 4, 5, 7, 7 and 1 point, respectively, with increasing loads. The median scores in the second test were 0 at resting and 0, 0, 2, 2, 3, 4, 4 and 0.5 points, respectively. The intra-class correlation coefficient was 0.57, 0.80, 0.74, 0.80, 0.83, 0.86, 0.91, and 0.92 for each resistive load, respectively. In a generalized linear model analysis, there was a statistically significant difference between the levels of resistive loads (p<0.001) and between tests (p=0.003). Dyspnea scores were significantly lower in the second test. Conclusion: The agreement between the two tests of the perception of dyspnea was only moderate and dyspnea scores were lower in the second test. These findings suggest a learning effect or an effect that could be at least partly attributed to desensitization of dyspnea sensation in the brain.

Background:Pedometer is the most convenient and economical objective tool which is progressively being used to assess physical activity in adolescents. The purpose of this study was to describe the overall and gender stratified physical activity levels and to determine minimal no. of reliable days for collecting pedometer data among Pakistani adolescents. Methods:Descriptive cross-sectional study was conducted in four schools of Karachi during 2017. A total of 265 adolescents (age 13-16 years) wore unsealed Ymax Digi Walker SW-200 pedometer for a duration of 7 days including both weekends and weekdays. Data were analyzed using SPSS version 21. Independent t test and ANOVA were used for gender based stratified physical activity levels whereas, Cronbach’s alpha and Intra class correlation coefficient (ICC) were used to ascertain the reliability of pedometer data. Results:The average recorded step counts per day were 10,010 (SD: ± 4926). However, boys took 12,513 (SD: ± 5365) steps / day than girls 7,809 (SD: ± 3168) and higher steps were recorded from Thursday to Saturday. The reliability of pedometer monitoring increases with increase in number of days. The maximum pedometer reliability ? = 0.91 was observed for 7 days. Conclusion:This study concludes that adolescents are more physical active, with slightly higher reported activity among boys compared to girls. It also proposes that at least 7 days pedometer data should be collected for the reliable estimation of adolescent’s physical activity. The resulting data provides key information regarding pedometer-determined physical activity which may be useful for formulating strategies and other interventions to increase level of adolescents physical activity.

The aim of this study was to evaluate the psychometric properties of the Brazilian version of Sense of Coherence scale (SOC-13) in schoolchildren. This is a cross-sectional study that included eight to fourteen years-old schoolchildren. The Cronbach's alpha coefficient for SOC-13 measurement presented questionable results (0.63) and the Intra-Class Correlation Coefficient of 0.70 was statistically significant between different time points (p<0.01). Regarding the construct validity, significant values were observed between the SOC-13 components scores and the overall scale score. In the Confirmatory Factorial Analysis, the latent variable was related, through the standard factorial loads, to the other items of the questionnaire. We can conclude that the Brazilian version of SOC-13 showed adequate psychometric properties in a school-age population.

Background: A force platform must have validity and reliability for optimal use. The objective of this study was to analyze the validity and the reliability of the Satel 40 Hz stabilometric force platform. Methods: A study of instrumental validity and reliability, involving a cross-sectional correlational and comparative analysis was performed. To determine the validity, four certified weights located on three axes were used and the ability of the stabilometric force platform to detect changes in the position of the different axes was observed. A test–retest was performed to analyze the reliability. Forty-two symptom-free volunteers participated in the study. Assessments were taken in a standing static position and in a dynamic position, with the eyes open and closed. Three measurements were taken and the intra-class correlation coefficient (ICC) was calculated. Results: The validity increased as the weight increased for all the variables measured in the stabilometric parameters (p < 0.05). The reliability was shown to be good to excellent for the two visual conditions. The positional variables obtained a higher ICC. The variable with the best ICC was the Y mean in OE (ICC 0.874 and a p < 0.001). All the values showed an increase in a dynamic situation. Conclusion: The findings support the reliability and validity of the Satel 40 Hz stabilometric force platform. The platform could be recommended to evaluate static and dynamic standing balance in healthy adult individuals. Guidelines for treatment and the level of quality of stabilometry could be obtained from its use.

IntroductionUltrasound imaging (USI) is useful to evaluate structures of the foot to guide treatment, but the reliability of USI technique needs to be clarified. The goal of the study was to evaluate the intra- and inter-examiner reliability of USI image capture, and measurement of the cross-sectional area (CSA) and thickness of the flexor hallucis longus (FHL) for experienced and novice examinersMaterial and methodsFHL images were captured for 20 healthy adults. Reliability of image capture was evaluated between images repeated at 10-min interval for an experienced and a novice examiner. Reliability of image-based measurements was evaluated for one experienced and one novice rater, using all images. The intra-class correlation coefficient (ICC) and the standard error of measurement (SEM) were calculatedResultsIntra-examiner reliability of image capture for the FHL muscle examined by USI was excellent for both thickness (ICC3,1, 0.944–0.976; SEM, 6.8%–10.0%) and CSA (ICC3,1, 0.954–0.979; SEM, 10.8%–16.5%), with no effect of examiner experience. Reliability was also excellent for measurement of thickness (ICC3,1, 0.954–0.972; SEM, 1.2%–9.6%) and CSA (ICC3,1, 0.961–0.986; SEM, 9.2%–14.1%), with no effects of experience.ConclusionsReliability of image capture and image-based measurements developed by USI of CSA and thickness for the FHL muscle in healthy individuals was excellent, independent of the examiner experience.

Improvement in rider mobility represents an important functional gain for people with disabilities undergoing hippotherapy. However, there is no validated measuring instrument to track and document the rider's progress in riding activities. In this study, we aimed to develop and establish validity evidence for an instrument to assess hippotherapy participants’ mobility on horseback. We report on this development through the stages of: (a) content validation, (b) construct validation, (c) inter- and intra-rater reliability and (d) internal consistency analysis. We evaluated its factor structure with exploratory factor analyses, calculated values for inter- and intra-rater reliability using the intra-class correlation coefficient, and calculated its internal consistency using Cronbach's alpha. We followed recommendations by the Guidelines for Reporting Reliability and Agreement Studies. We found good inter-rater reliability (intra-class correlation coefficient – ICC = 0.991–0.999) and good intra-rater reliability (ICC = 0.997–1.0), and there was excellent internal consistency (Cronbach's α = 0.937–0.999). The instrument’s factor structure grouped its three domains into one factor. As this instrument is theoretically consistent and has been found to be appropriate and reliable for its intended use, it is now available for the measurement of horseback mobility among hippotherapy riders.

ObjectiveTo examine the effect of the consumption of ultraprocessed food on diet quality, and cardiometabolic risk (CMR) in an occupational cohort.DesignCross-sectional.SettingOccupational cohort.Participants53 163 British police force employees enrolled (2004–2012) into the Airwave Health Monitoring Study. A total of 28 forces across the UK agreed to participate. 9009 participants with available 7-day diet record data and complete co-variate data are reported in this study.Main outcome measuresA CMR and Dietary Approaches to Stop Hypertension score were treated as continuous variables and used to generate measures of cardiometabolic health and diet quality. Secondary outcome measures include percentage of energy from fat, saturated fat, carbohydrate, protein and non-milk extrinsic sugars (NMES) and fibre grams per 1000 kcal of energy intake.ResultsIn this cohort, 58.3%±11.6 of total energy intake was derived from ultraprocessed (NOVA 4) foods. Ultraprocessed food intake was negatively correlated with diet quality (r=−0.32, p<0.001), fibre (r=−0.20, p<0.001) and protein (r = −0.40, p<0.001) and positively correlated with fat (r=0.18, p<0.001), saturated fat (r=0.14, p<0.001) and nmes (r=0.10, p<0.001) intake . Multivariable analysis suggests a positive association between ultraprocessed food (NOVA 4) consumption and CMR. However, this main effect was no longer observed after adjustment for diet quality (p=0.209). Findings from mediation analysis indicate that the effect of ultraprocessed food (NOVA 4) intake on CMR is mediated by diet quality (p<0.001).ConclusionsUltraprocessed food consumption is associated with a deterioration in diet quality and positively associated with CMR, although this association is mediated by and dependent on the quality of the diet. The negative impact of ultraprocessed food consumption on diet quality needs to be addressed and controlled studies are needed to fully comprehend whether the relationship between ultraprocessed food consumption and health is independent to its relationship with poor diet quality.

AbstractBackgroundAdolescent girls are vulnerable to many problems, undernutrition being the most common. This results in growth restriction resulting in stunting, wasting, underweight and last but not the least iron-deficiency anaemia. Nutritional needs are high during puberty which later leads to complications during pregnancy and its outcomes.Materials and methodsA field based cross-sectional study was carried out to assess the nutritional status of the girls and to determine the various factors responsible for undernutrition. After clearance from the Institution Ethical Committee (IEC) and permission from Child Development Programme Officer (CDPO), the study was conducted in the anganwadi centres (AWC) of urban slums in the field practice area of the Department of Community Medicine from the 1st October 2014 to the 31st October 2016. All the adolescent girls enlisted in the seven anganwadi centres were included as study subjects with their consent. A pre-designed, pre-tested and semi-structured questionnaire was used to collect data on following sections. (a) socio-demographic profile and (b) nutritional status. Dietary intake was taken using the 24-h recall method. Anthropometry was measured and haemoglobin (Hb) was estimated. SPSS version 21 was used for descriptive and analytic statistics.ResultsAmong the 160 girls 98(61.3%), 69(43.1%), 53(33.1%) were underweight, stunted and wasted, respectively. Anaemia was present among 144(90%) of the girls.ConclusionStrict monitoring of weekly iron and folic acid supplementation (WIFS) as well as nutrition education are essential measures to solve the problem of undernutrition among adolescent girls.
