<html> تدابير تكوين الجسم دقيقة حاسمة لتقييم النمو في مرحلة الطفولة في الدراسات البحثية بشكل صحيح. الباحثون يقبل على نطاق واسع DXA كوسيلة معيار الذهب، والعديد انتقاد التدابير الجسم البشري اليدوي بأنها غير دقيقة وغير دقيقة. ومع ذلك، هذا التحليل من تقنيات القياسات البشرية...

تبقى زيادة الوزن والسمنة في مستويات وبائية، مع ما يقرب من ثلث الأطفال الولايات المتحدة وثلثي البالغين وجود زيادة الوزن أو السمنة، وفقا ل2011 - 2012 وتقدر 2. زيادة الوزن، والسمنة، والدهون الزائدة في الجسم تمنح خطر أكبر من النتائج cardiometabolic السلبية، بما في ذلك مرض السكري من النوع 2 وأمراض القلب والأوعية الدموية، فضلا عن غيرها من النتائج الصحية البدنية والنفسية السلبية، بما في ذلك الربو والاكتئاب 3، 4، 5، 6. معظم الدراسات التي تدرس الارتباط بين السمنة والنتائج الصحية في وقت لاحق للحياة تفترض قياسات دقيقة من الوزن والطول / الارتفاع. وتشمل فئات من وضع الوزن لدى البالغين والأطفال ناقصي الوزن (مؤشر كتلة الجسم (BMI) &lt;18.0 كغ / م 2 للكبار و&lt;الموافق 5 العمر الجنس محددة المئوية للأطفال)، أي<html> الوزن rmal (BMI 18.0 إلى &lt;25.0 كغ / م 2 للكبار و 5 عشر إلى &lt;85 المئين الخامس للأطفال)، زيادة الوزن (مؤشر كتلة الجسم 25.0 إلى &lt;30.0 كغ / م 2 للبالغين و 85 مارس إلى &lt;95 المئين الخامس للأطفال) ، والسمنة (BMI ≥ 30 كغ / م 2 للكبار و≥ 95 المئين الخامس للأطفال). يمكن حتى أخطاء القياس طفيفة تؤثر هذه التصنيفات، وخاصة في الأطفال الذين الأخطاء التي تظهر صغيرة على نطاق المطلق يمكن أن يمثل خطأ كبير بالنسبة لحجم الطفل 7. على سبيل المثال، في دراسة مسبقة للأطفال دون سن 2 سنة من العمر، ومقارنات بين طول تقاس طريقة الورق والقلم السريرية التقليدية مع راقد طريقة طول متن أشار إلى أن طريقة الورق والقلم بالغت بشكل منتظم طول بمتوسط 1.3 (1.5) سم - خطأ أن يؤدي إلى الخطأ في التصنيف كبير 7. الحمار = &quot;jove_content&quot;&gt; استخدام مؤشر كتلة الجسم لتقدير السمنة يوفر مزايا عديدة للبحث، بما في ذلك انخفاض تكلفة المعدات وعبء الحد الأدنى من الطول وقياس الوزن، وكذلك فرصة للاستفادة من تقرير المصير والتدابير السريرية. ولكن، حتى مع القياس الدقيق للالطول والوزن، لا يعكس التباين في مؤشر كتلة الجسم بالضرورة الاختلاف في السمنة، منذ BMI تضم كلا الهزيل والدهون كتلة 1. وبالتالي، الأساليب التي تقيس مباشرة السمنة هي مهمة لفهم العلاقات مع النتائج الصحية أيضا. طرق معيار الذهب من السمنة وقياس مكونات الجسم تعتمد عموما على الطرق التكنولوجية، بما في ذلك تخطيط التحجم تشريد الهواء (ADP)، الهيدروستاتيكي وزنها، والتصوير بالرنين المغناطيسي (MRI)، والتصوير المقطعي (CT)، وكذلك قياس امتصاص مزدوج الأشعة السينية (DXA ) 8، 9، 10. في حين أن هذهطرق توفر بعض التدابير الأكثر دقة لتكوين الجسم، وكثير منهم ليسوا العملي في الدراسات البحثية للأطفال، وخاصة تلك التي هي في الميدان. على سبيل المثال، الهيدروستاتيكي وزنها يتطلب أن الأفراد أن يغطس في الماء تماما. معدات ADP لديها، حتى وقت قريب، كانت متاحة فقط لقياس الرضع يصل إلى 8 كجم أو الأطفال والبالغين الذين تزيد أعمارهم عن 6 سنوات، ولكن ليس الأطفال الصغار أو الأطفال في سن ما قبل المدرسة. الأشعة المقطعية تنبعث كمية كبيرة من الإشعاع مقارنة مع التقنيات الأخرى، واكتساب الوقت الطويل للتصوير بالرنين المغناطيسي يجعل من غير العملي للعديد من الدراسات 8. DXA تنبعث حول 1/500 جرعة الاشعاع من الاشعة المقطعية، تقريبا أي ما يعادل يوم واحد من إشعاع الخلفية الطبيعية 11، مما يجعلها خيارا جذابا للدراسات الأبحاث التي تصيب الأطفال. كل من هذه الطرق، ومع ذلك، هي مكلفة لشراء ولا يوجد اي المحمولة، مما يجعلها غير ممكنة لدراسات ميدانية مع صندوق محدودجي. تحليل المعاوقة الكهربائية البيولوجية (BIA)، الذي يقيس مقاومة للإشارة الكهربائية الدقيقة التي يتم إرسالها عبر الجسم لتقدير تكوين الجسم، يمكن أن يكون أقل تكلفة وأكثر المحمولة، ولكن الافتراضات التي يقوم عليها حساب الدهون في الجسم ولا تنطبق على الأطفال الصغار 10. وعلى النقيض من هذه التدابير القائمة على التكنولوجيا، وتدابير الجسم البشري اليدوي لا يمكن أن يؤديها من قبل مراقب تدريب في معظم البيئات الميدانية وبتكلفة أقل بكثير المعدات. ويشمل القياسات الجسمية اليدوي قياسات الطول والوزن ومحيطه، وسمك طبقات الجلد 8. من المزايا الأخرى من القياسات الجسمية اليدوي هي أنه لا ينطوي على أي التعرض للإشعاع غير ضرورية، ويمكن للموظفين المهرة الحصول عليها بكفاءة. ومع ذلك، فإن الاهتمام المشترك حول القياسات البشرية اليدوي هو أنها قد تكون على حد سواء غير دقيقة وغير دقيق 12. الحصول على معلومات دقيقة والعلاقات العامةقياسات ecise ممكنة مع إجراءات موحدة والتدريب الكافي، والاهتمام الكافي لإجراءات (QC) مراقبة الجودة. وقد وضعت فريق المشروع فيفا بروتوكول التدريب القياسات الجسمية اليدوي الذي يمكن أن يحقق ذات جودة عالية، والتدابير استنساخه من مكانه، محيطه، وسمك طبقات الجلد. على مدى أكثر من عقد من الزمان، وقد طبقنا هذا التدريب وبروتوكول مراقبة الجودة للأمهات والأطفال في مشروع فيفا، لفيف دراسة طولية، قبل الولادة (13). موظفي المشروع فيفا جمع التدابير القياسات البشرية على الأطفال أثناء الزيارات عند الولادة (0-3 أيام)، ومع كل من الأم والطفل في النقاط الزمنية التالية: الطفولة (4،9 حتي 10،6 أشهر)، في مرحلة الطفولة المبكرة (2،8-6،3 سنوات)، منتصف -childhood (6،6 حتي 10،9 سنة)، وفي سن المراهقة في وقت مبكر (11،5-16،5 سنوات) 13. وتصف هذه الورقة بروتوكول قمنا بتطوير وصقل لقياس الطول والوزن وسمك ثنية الجلد (ثلاثية الرؤوس وsubscapulع skinfolds)، ومحيطات الجسم (الخصر، والورك، ومحيطات منتصف العضد [مقياس محيط العضد]) في مشروع فيفا. نحن أيضا وصف كيف أننا قمنا بتقييم دليل على حد سواء دقة قياس الجسم البشري عن طريق الخطأ الفني للقياس (تيم) الحسابات ودقة في مقارنة لقياسات DXA القياسية الذهب.

A Method for Manipulating Blood Glucose and Measuring Resulting Changes in Cognitive Accessibility of Target Stimuli

Much research in social psychology has investigated the impact of bodily energy need on cognition and decision-making. As such, blood glucose, the body's primary energy source, has been of special interest to researchers for years. Fluctuations in blood glucose have been linked to a variety of changes in cognitive and behavioral processes, such as self-control, political attitudes, and eating behavior. To help meet growing interest in the links between bodily energy need and these processes, this manuscript offers a simple methodology to experimentally manipulate blood glucose using a fasting procedure followed by administration of a sugar-sweetened, unsweetened, or artificially-sweetened beverage. This is followed by presentation of a method for measuring resulting changes in implicit cognition using a lexical decision-task. In this task, participants are asked to identify whether strings of letters are words or non-words and response latencies are recorded. Sample results from a recent publication are presented as an example of the applications for the experimental manipulation of blood glucose and the lexical decision task measures.

The authors introduce a method for manipulating blood glucose and measuring resulting changes in cognitive accessibility of target words using a lexical decision task.

Measuring Cardiac Autonomic Nervous System (ANS) Activity in Children

The autonomic nervous system (ANS) controls mainly automatic bodily functions that are engaged in homeostasis, like heart rate, digestion, respiratory rate, salivation, perspiration and renal function. The ANS has two main branches: the sympathetic nervous system, preparing the human body for action in times of danger and stress, and the parasympathetic nervous system, which regulates the resting state of the body.
ANS activity can be measured invasively, for instance by radiotracer techniques or microelectrode recording from superficial nerves, or it can be measured non-invasively by using changes in an organ's response as a proxy for changes in ANS activity, for instance of the sweat glands or the heart. Invasive measurements have the highest validity but are very poorly feasible in large scale samples where non-invasive measures are the preferred approach. Autonomic effects on the heart can be reliably quantified by the recording of the electrocardiogram (ECG) in combination with the impedance cardiogram (ICG), which reflects the changes in thorax impedance in response to respiration and the ejection of blood from the ventricle into the aorta. From the respiration and ECG signals, respiratory sinus arrhythmia can be extracted as a measure of cardiac parasympathetic control. From the ECG and the left ventricular ejection signals, the preejection period can be extracted as a measure of cardiac sympathetic control. ECG and ICG recording is mostly done in laboratory settings. However, having the subjects report to a laboratory greatly reduces ecological validity, is not always doable in large scale epidemiological studies, and can be intimidating for young children. An ambulatory device for ECG and ICG simultaneously resolves these three problems.
Here, we present a study design for a minimally invasive and rapid assessment of cardiac autonomic control in children, using a validated ambulatory device 1-5, the VU University Ambulatory Monitoring System (VU-AMS, Amsterdam, the Netherlands,<a href="http://www.vu-ams.nl" target="_blank"> www.vu-ams.nl</a>).

Measuring Cardiac Autonomic Nervous System ANS Activity in Children

Measurement of autonomic nervous system activity usually confines the researcher and participant to the laboratory, which may provide an intimidating environment to children. The VU University Ambulatory Monitoring System (VU-AMS) device can record cardiac autonomic control in any setting. The VU-AMS proved very amenable to testing in children.

Sample Preparation to Bioinformatics Analysis of DNA Methylation: Association Strategy for Obesity and Related Trait Studies

Obesity is directly connected to lifestyle and has been associated with DNA methylation changes that may cause alterations in the adipogenesis and lipid storage processes contributing to the development of the disease. We demonstrate a complete protocol from selection to epigenetic data analysis of patients with and without obesity. All steps from the protocol were tested and validated in a pilot study. 32 women participated in the study, in which 15 individuals were classified with obesity according to Body Mass Index (BMI) (45.1 &#177; 5.4 kg/m2); and 17 individuals were classified without obesity according to BMI (22.6 &#177; 1.8 kg/m2). In the group with obesity, 564 CpG sites related to fat mass were identified by linear regression analysis. The CpG sites were in the promoter regions. The differential analysis found 470 CpGs hypomethylated and 94 hypermethylated sites in individuals with obesity. The most hypomethylated enriched pathwayswere in the RUNX, WNT signaling, and response to hypoxia. The hypermethylated pathways were related to insulin secretion, glucagon signaling, and Ca2+. We conclude that the protocol effectively identified DNA methylation patterns and trait-related DNA methylation. These patterns could be associated with altered gene expression, affecting adipogenesis and lipid storage. Our results confirmed that an obesogenic lifestyle could promote epigenetic changes in human DNA.

The present study describes the workflow to manage DNA methylation data obtained by microarray technologies. The protocol demonstrates steps from sample preparation to data analysis. All procedures are described in detail, and the video shows the significant steps.

Physical Activity Measurement in Children Accepting Table Tennis Training

An increasing body of evidence now shows that the majority of children in China experience lower levels of physical activity (PA) than the recommended guideline. Table tennis is a compound and technically difficult game that is popular in China; undertaking table tennis training in clubs can help children to elevate their levels of PA. Given that children cannot complete self-evaluated questionnaires themselves and caregiver-based observations are not suitable for children, we hypothesized that an actigraphy-based method can be an objective method to measure PA. In the present study, we describe a procedure that can be used to evaluate PA levels using an actigraphic device and software. Furthermore, since hip-worn devices are known to reduce compliance, we attempted to assess the agreement between hip-worn and wrist-worn device data. Collectively, our results indicate that these devices are suitable for measuring PA and leisure time physical activity (LTPA) levels. Together with subjective questionnaires, both hip-worn and wrist-worn devices are highly suitable for evaluating PA in Chinese children undergoing table tennis training in clubs.

This study proposes an accelerometer-based method to objectively measure physical activity (PA) and leisure time physical activity (LTPA) in Chinese children accepting table tennis training in clubs.

Scanning Skeletal Remains for Bone Mineral Density in Forensic Contexts

The purpose of this paper is to introduce a promising, novel method to aid in the assessment of bone quality in forensically relevant skeletal remains. BMD is an important component of bone&#39;s nutritional status and in skeletal remains of both juveniles and adults, and it can provide information about bone quality. For adults remains, it can provide information on pathological conditions or when bone insufficiency may have occurred. In juveniles, it provides a useful metric to elucidate cases of fatal starvation or neglect, which are generally difficult to identify. This paper provides a protocol for the anatomical orientation and analysis of skeletal remains for scanning via dual-energy X-ray absorptiometry (DXA). Three case studies are presented to illustrate when DXA scans can be informative to the forensic practitioner. The first case study presents an individual with observed longitudinal fractures in the weight bearing bones and DXA is used to assess bone insufficiency. BMD is found to be normal suggesting another etiology for the fracture pattern present. The second case study employed DXA to investigate suspected chronic malnutrition. The BMD results are consistent with results from long bone lengths and suggest the juvenile had suffered from chronic malnutrition. The final case study provides an example where fatal starvation in a fourteen-month infant is suspected, which supports autopsy findings of fatal starvation. DXA scans showed low bone mineral density for chronological age and is substantiated by traditional assessments of infant health. However, when dealing with skeletal remains taphonomic alterations should be considered before applying this method.

Bone mineral density (BMD) is an important factor in understanding nutritional intake. For human skeletal remains, it is a useful metric to assess quality of life in both juveniles and adults, particularly in fatal starvation and neglect cases. This paper provides guidelines for scanning human skeletal remains for forensic purposes.

'Boden Food Plate': Novel Interactive Web-based Method for the Assessment of Dietary Intake

Different methods can be used in research to assess dietary intake, many of which are still paper-based. Written estimated food diaries are often utilized in clinical trials, despite being a burden for both study participants and researchers. This method requires participant literacy, it is time consuming, labor intensive, and can easily lead to under-reporting. With advancements in technology, there is a growing interest in electronic diaries that automate the dietary assessment process. These are focused on improving accuracy, reducing both time and cost and providing users with a visual and more enjoyable experience. The methodology presented here aimed to validate the &#39;Boden Food Plate&#39;, a novel web-based platform for self-recording of food and drink items, compared to a traditional estimated food diary. The application was also rated on a satisfaction scale by study participants using a paper-based questionnaire. Sixty-seven participants completed the dietary measures on both the three-day electronic and paper food diaries. For the analysis, only dietary data completed at both study time points (baseline and week six) was utilized. Despite small mean differences between dietary data collection methods, Bland Altman analysis showed fairly wide 95% limits of agreement between the electronic platform and the written estimated food diary and there were few cases which did not fall within the 95% confidence intervals. Overall, participants found the electronic food diary to be more fun than the paper method and as easy to use as hard copy diaries. The new platform has potential as a self-recording tool for the collection of dietary data, particularly when utilized in clinical trial settings. However, further validation studies are needed to improve the validity of this novel electronic dietary data collection tool.

The &#39;Boden Food Plate&#39; is an electronic food diary designed to be an interactive and fun method to collect dietary intake using visual depictions. The purpose of this study was to validate the web-based application against a traditional three-day estimated food diary method.

Quantified Assessment of Infant's Gross Motor Abilities Using a Multisensor Wearable

Developing objective and quantitative methods of early gross motor assessment is essential to better understand neurodevelopment and to support early therapeutic interventions. Here, we&#160;present&#160;a method to quantify gross motor performance using a multisensor wearable, MAIJU (Motility Assessment of Infants with a JUmpsuit), which offers an automated, scalable,&#160;quantitative, and objective assessment using&#160;a fully automated cloud-based pipeline. This wearable suit is equipped with four movement sensors that record synchronized data to a mobile phone utilizing a low-energy Bluetooth connection. An offline analysis in the cloud server generates fully analyzed results within minutes for each recording. These results include a graphical report of the recording session and a detailed result matrix that gives second-by-second classifications for posture, movement, infant carrying, and free playtime. Our recent results show the virtue of such&#160;quantified motor assessment&#160;providing&#160;a potentially&#160;effective method for distinguishing variations in the infant&#39;s gross motor development.

This paper outlines the assessment of infants' gross motor performance with a multisensor wearable and its fully automated deep learning-based analysis pipeline. The method quantifies the posture and movement patterns of infants from lying supine until they master walking independently.

Impact of Underweight Status on Retinal and Choroidal Thickness

Determining Gender-Based Differences in Retinal and Choroidal Thickness in Underweight Individuals via Swept-Source Optical Coherence Tomography

Despite improvements in reducing hunger in recent years, undernutrition remains a global public health problem. This study utilizes the swept-source optical coherence tomography (SS-OCT) technique to assess changes in retinal and choroidal thickness in underweight subjects. Ophthalmic examinations were conducted on all adults participating in this cross-sectional research. Depending on their body mass index (BMI), the participants were divided into two groups: the underweight group and the normal group. The study included the right eyes of the underweight adults and an equal number of age- and gender-matched normal-weight subjects. The retinal thickness showed no significant difference between the underweight and normal groups (P &gt; 0.05 for all). In males, the retina of the center and inner ring in the underweight group was significantly thinner than that in the normal group, while no such results were found in females. The choroid in the underweight group was significantly thinner compared to that in the normal group (all P &lt; 0.05). Being underweight may affect choroidal thickness in both males and females. In comparison with underweight females, underweight males may experience more retinal damage. These findings contribute to a better understanding of the pathogenesis underlying specific ocular diseases in malnourished individuals.

Here, swept-source optical coherence tomography (SS-OCT) is used to compare retinal and choroidal thickness in adults with and without malnutrition, contributing to a better understanding of the pathogenesis of ocular diseases in malnourished individuals.

Clinical Anthropometrics and Body Composition from 3-Dimensional Optical Imaging

The body size and composition assessment is commonly included in the routine management of healthy athletes as well as of different types of patients to personalize the training or rehabilitation strategy. The digital anthropometric analyses described in the following protocol can be performed with recently introduced systems. These new tools and approaches have the potential to be widely used in clinical settings because they are very simple to operate and enable the rapid collection of accurate and reproducible data. One system consists of a rotating platform with a weight measurement plate, three infrared cameras, and a tablet built into a tower, while the other system consists of a tablet mounted on a holder. After image capture, the software of both systems generates a de-identified three-dimensional humanoid avatar with associated anthropometric and body composition variables. The measurement procedures are simple: a subject can be tested in a few minutes and a comprehensive report (including the three-dimensional scan and body size, shape, and composition measurements) is automatically generated.
