Qualidade dos dados antropométricos de crianças menores de cinco anos em sistemas de informação no estado de São Paulo, Brasil / The quality of the anthropometric data on children under five years of age in information systems in the State of São Paulo, Brazil

Resumo O objetivo foi analisar a qualidade dos dados antropométricos de crianças menores de cinco anos em dois sistemas de informação no estado de São Paulo. A amostra compreendeu 2.117.108 crianças do Sistema de Vigilância Alimentar e Nutricional (Sisvan) e 748.551 do Projeto Estadual do Leite (Vivaleite). Inicialmente, avaliamos a frequência de valores faltantes e fora do espectro do equipamento, e calculamos o índice de preferência de dígito para peso. Após calcular os índices de altura para idade (A-I), peso para idade (P-I) e índice de massa corporal para idade (IMC-I), identificamos os valores biologicamente implausíveis (VBI) e calculamos o desvio-padrão (DP). Para cada município, calculamos a média e o DP de A-I, P-I e IMC-I; e plotamos os valores de DP em função da média. A preferência de dígito no peso foi maior em crianças de 24 a 59 meses no Sisvan. A frequência de VBI para A-I (SISVAN 2,56%; Vivaleite 0,98%) foi maior do que para P-I (Sisvan 2,10%; Vivaleite 0,18%). Para o índice A-I as variações entre os municípios foram mais acentuadas no Vivaleite do que no Sisvan. A variável altura apresentou baixa confiabilidade nos dois sistemas. A variável peso apresentou qualidade satisfatória no Vivaleite e insatisfatória no Sisvan.

Abstract This paper involves the analysis of the quality of anthropometric data on children under five years of age in two information systems in the State of São Paulo. The sample included 2,117,108 children from the Food and Nutrition Surveillance System (SISVAN), and 748,551 from the State Milk Project (VIVALEITE). Initially, we evaluated the frequency of missing values and others outside the equipment spectrum and calculated the digit-to-weight preference index. After calculating height-for-age (HAZ), weight-for-age (WAZ), and body mass index-for-age (BAZ), we flagged the biologically implausible values (BIV) and calculated the standard deviation (SD). For each municipality, we calculated the mean and the SD of HAZ, WAZ, and BAZ; and plotted the SD values as a function of the mean. The digit-to-weight preference index was greater among children aged between 24 and 59 months in SISVAN. The frequency of BIV for HAZ (SISVAN 2.56%; VIVALEITE 0.98%) was higher than for WAZ (SISVAN 2.10%; VIVALEITE 0.18%). For HAZ, variations among municipalities were more pronounced in VIVALEITE than in SISVAN. The height variable presents low reliability in both systems. The weight variable reveals satisfactory quality in VIVALEITE and unsatisfactory quality in SISVAN.

Portuguese version of the Short-Form Condom Attitude Scale and psychometric properties among undergraduate students / Versão em português da Short-Form Condom Attitude Scale e propriedades psicométricas entre estudantes universitários

Abstract The condom use can be influenced by psychological and sociocultural aspects, which can be modulated by individual's attitudes. The aim was to propose a Brazilian Portuguese version of the Short-Form Condom Attitude Scale (Short-Form CAS), describing all procedures of translation, transcultural adaptation, and psychometric properties evaluation when applied to undergraduate students. A cross sectional study was conducted among students enrolled at University of São Paulo (USP), Campus Ribeirão Preto (n = 491; 61.2% female; average age: 22 years; standard deviation: four years). Confirmatory factor analysis was performed. A one-factor model with seven items exhibited good factorial validity and reliability, suggesting to be a better factorial solution of the Short-Form CAS in the sample. Few studies have been carried out on the behavioral factors associated with condom use in key populations, which can be exacerbated by a lack of appropriate scales. Therefore, the main contribution of the present study was to propose a simplified and transculturally adapted version of the Short-form CAS with some psychometric properties verified. Since the use of condoms is a component of the study of sexual risk behavior, this scale might be an option to be applied in various Brazilian population segments for this purpose.

Resumo O uso de preservativos pode ser influenciado por aspectos psicológicos e socioculturais, que podem ser modulados por atitudes individuais. O objetivo foi propor uma versão em português brasileiro da Short-Form Condom Attitude Scale (Short-Form CAS), descrevendo os procedimentos de tradução, adaptação transcultural e avaliação das propriedades psicométricas em uma amostra de universitários. Trata-se de estudo transversal com estudantes matriculados na Universidade de São Paulo (USP), Campus Ribeirão Preto (n = 491; 61,2% feminino; média de idade: 22 anos; desvio-padrão: quatro anos). Foi realizada análise fatorial confirmatória. O modelo unifatorial com sete itens apresentou boa validade fatorial e confiabilidade, sugerindo ser a melhor solução fatorial para a Short-Form CAS. Há poucos estudos sobre os fatores comportamentais associados ao uso de preservativos em populações-chave, o que pode ser influenciado pela falta de instrumentos. A principal contribuição deste estudo foi propor uma versão simples e adaptada transculturalmente da Short-Form CAS com algumas propriedades psicométricas verificadas. Uma vez que o uso de preservativos é um componente do comportamento sexual de risco, a escala se apresenta como uma nova opção para futuros estudos na população brasileira.

Evaluación de la consistencia interna y dimensionalidad de la Escala de Capital Social Cognitivo en adultos colombianos

Introducción: durante las últimas dos décadas, el concepto de capital social se ha utilizado con creciente frecuencia en las ciencias de la salud debido a las relaciones directas e indirectas entre el capital social y la salud física y mental de las poblaciones. Por tanto, es necesario construir un instrumento para cuantificar este concepto con seguridad y confiabilidad. Objetivo: analizar la consistencia interna y dimensionalidad de una escala de siete ítems para medir el capital social en adultos de la población general de Colombia. Metodología: se realizó un estudio de validación en línea, que incluyó una muestra de 700 adultos de entre 18 y 76 años, el 68 % eran mujeres. Los participantes completaron una escala de siete ítems llamada Escala de Capital Social Cognitivo (ECSC). El alfa de Cronbach y el omega de McDonald se calcularon para probar la consistencia interna. Se realizaron análisis factoriales exploratorios y confirmatorios para explorar la dimensionalidad de la ECSC. Resultados: la ECSC presentó una consistencia interna baja (alfa de Cronbach de 0,56 y omega de McDonald de 0,59) y pobre dimensionalidad. Seguidamente, se probó una versión de cinco ítems (ECSC-5). La ECSC-5 mostró una alta consistencia interna (alfa de Cronbach de 0,79 y omega de McDonald de 0,80) y una estructura unidimensional con indicadores de bondad de ajuste aceptables. Discusión: la ECSC-5 presenta alta consistencia interna y una estructura unidimensional para medir el capital cognitivo social en adultos colombianos. Se recomienda la ECSC-5 para la medición del capital social en la población general colombiana. Futuras investigaciones deben corroborar estos hallazgos en aplicaciones de lápiz y papel y explorar otros indicadores de confiabilidad y validez.

Introduction: During the last two decades, the concept of social capital has been used increasingly frequently in health sciences due to the direct and indirect relationships between social capital and populations' physical and mental health. Therefore, it is necessary to build an instrument to quantify this concept confidently and reliably. Objective: The study aimed to internal consistency and dimensionality of a seven-item scale to measure social capital in Colombia's general population of adults. Methods: An online validation study included a sample of 700 adults aged between 18 and 76 years; 68% were females. Participants completed a seven-item scale called the Cognitive Social Capital Scale (CSCS). Cronbach's alpha and McDonald's omega were computed to test internal consistency. The authors explore the internal consistency and dimensionality of the CSCS. Results: The CSCS presented a low internal consistency (Cronbach's alpha of 0.56 and McDonald's omega of 0.59) and poor dimensionality. Then, the researchers tested a five-item version (CSCS-5). The CSCS-5 showed high internal consistency (Cronbach's alpha of 0.79 and McDonald's omega of 0.80) and a one-dimension structure with acceptable goodness-of-fit indicators. Discussion: The CSCS-5 presents high internal consistency and a one-dimensional structure to measure cognitive capital social in the Colombian sample. Authors can recommend measuring social capital in the general Colombian population. Further research should corroborate this pencil and paper application findings and explore other reliability and validity indicators.

Validación de cuestionarios para la medición de variables en salud: conceptos fundamentales / Validation of questionnaires for the measurement of health variables: fundamental concepts

Dentro de la práctica clínica, así como en la salud poblacional, es habitual utilizar cuestionarios que permiten evaluar condiciones o variables que no son directamente observables. No obstante, la construcción y validación de estos instrumentos o cuestionarios suele ser poco conocida. El objetivo de esta revisión narrativa es sintetizar de manera general el proceso de construcción y validación de estos cuestionarios, para así tener una mejor comprensión de este proceso, de los aspectos que se evalúan y de la mejor forma de utilizarlos. La validación de cuestionarios corresponde a un proceso de análisis de este, cuya finalidad es medir una variable latente o constructo, así como sus dimensiones, las que no pueden ser observadas directamente. Una variable latente puede ser inferida a través de un conjunto de atributos específicos que forman parte de ella, como los ítems de un cuestionario y que sí son observables. En este artículo se abordan de manera teórica los conceptos fundamentales de validación de cuestionarios o test, variables latentes o constructos, estudio de la confiabilidad y de la validez, así como los factores que afectan a estas dos últimas características, a través de una revisión narrativa. En el texto, se presentan ejemplos sobre estos conceptos.

In clinical practice and population health, it is common to use questionnaires to assess conditions or variables that are not directly observable. However, the construction and validation of these instruments or questionnaires are often poorly understood. This narrative review aims to summarize in a general way the process of construction and validation of these questionnaires in order to have a better understanding of this process, the aspects that are evaluated, and the best way to use them. The validation of questionnaires corresponds to a process of analysis of the questionnaire, aiming to measure a latent variable and its dimensions, which cannot be observed directly. A latent variable can be inferred through a set of specific attributes that are part of it, such as the items of a questionnaire, which are observable. Through a narrative review, this article addresses the fundamental concepts of questionnaire or test validation, latent variables or constructs, reliability and validity studies, and the factors that theoretically affect the latter two characteristics. Examples of these concepts are presented in the text.

Reliability of Pod Shape Diagram from Caloric Test in Vertigo Patients / 听力学及言语疾病杂志

Objective To understand the reliability of caloric test results through the analysis of the pod shape dia-gram types of caloric test and to provide a more accurate and reliable basis for vestibular system function evaluation.Meth-ods The results of caloric test in 528 patients from July 2021 to May 2022 in vertigo diagnosis and treatment center were analyzed.According to pod pattern and unilateral weakness(UW),the patients were divided into five groups:cold and warm test symmetrical group,left and right side asymmetry group,single value significant abnormal group,bilateral hypo-plasia group and pod morphology unable to be classified group.Unreliable data can be identified by comparing,explaining,and summarizing the results of UW of different groups,so as to reduce the interference of unreliable data to clinical diagno-sis and treatment.Results Cold and warm test symmetric group(n=439)included patients with symmetry of bilateral vestibular function(n=273)and decreased vestibular function of one side(n=166).Left and right symmetrical groups in-eluded pationts with bilateral symmetric vestibular function(n=11)and unilateral reduction(n=13).Single value signifi-cant abnormal group showed cases with unilateral vestibular function reduction(n=25)and bilateral symmetric vestibular function(n=11).Bilateral hypolasion group showed cases with bilateral symmetric vestibular function(n=25)and unilat-eral reduction(n=9).Pod morphology unclassified group(n=5)suggested varions interference factors.Conduson When the function of the peripheral vestibular is symmetrical and normal,we should be alert to the existence of temperature effect,and should consider the inspection of the perfusion apparatus and the calibration of the irrigation temperature.When the function of the peripheral vestibular shows unilateral weakness,repeating the irrigation is recommended when the single value of the caloric test significantly increases or decreases.If there is no change,repeating the irrigation at the same tem-perature in the other ear or even repeating the whole caloric test are recommended.The UW value could not truly reflect the state of peripheral vestibular function when the caoric test produces bilateral weakness.Therefore,water irrigation could be used to make a correct judgment based on the medical history and other auxiliary examinations.It is of great significance to judge the effectiveness of caloric test comprehensively by combining the morphology of pod diagram with UW value.

BACKGROUND:Confirming the reliability and validity of the My jump 2 application for measuring lower limb vertical stiffness may offer the possibility of it as an alternative to the Kistler three-dimensional force platform for measuring lower limb stiffness. OBJECTIVE:To verify the reliability and validity of the My Jump 2 application in measuring lower limb vertical stiffness of college students. METHODS:The drop jump data of the participants were collected through the Kistler three-dimensional force platform and the My Jump 2 application,and the vertical stiffness of the participants'lower limb vertical stiffness was calculated.The intraclass correlation coefficient was used to analyze the data measured by the My Jump 2 application and the Kistler three-dimensional force platform,attempting to verify the reliability of the My Jump 2 application.The bias and average between the two devices were drawn into a Bland-Altman diagram to verify the consistency between the two test methods.Finally,the test-retest reliability of the My Jump 2 applications at 30 cm and 40 cm was analyzed using the Cronbach's alpha(α)and coefficient of variation.Pearson product-moment correlation was used to analyze the correlation of My Jump 2 applications. RESULTS AND CONCLUSION:My Jump 2 application has high reliability and validity when measuring the vertical stiffness of the lower limb.At the same time,due to its advantages of low cost,convenient portability and field testing for large samples,it can be used as an alternative to the Kistler three-dimensional force platform to test the vertical stiffness of the lower limb in college students and similar populations.

Computer aided design of 3D dental segmentation and its application scenarios / 中国组织工程研究

BACKGROUND:Traditional 3D dental segmentation methods usually utilize predefined spatial geometric features,such as curvature and normal vectors,as the reference information for tooth segmentation. OBJECTIVE:To propose an algorithm for complex 3D dental segmentation and deeply explore the correlation between segmentation results and application scenarios. METHODS:A 3D dental segmentation algorithm based on dual stream extraction of structural features and spatial features was established,and the modular design of split flow was used to avoid feature confusion.Among them,the attention mechanism on the structural feature flow was used to capture the fine-grained semantic information required for tooth segmentation,and the Tran Net based on the spatial feature flow was used to ensure the robustness of the model to complex tooth and jaw segmentation.This algorithm verified its effectiveness and reliability based on clinical datasets including healthy dental jaws and complex dental jaws such as missing teeth,malocclusion and dentition crowding.The segmentation performance of the model was measured in terms of overall accuracy,mean intersection over union,and directional cut discrepancy. RESULTS AND CONCLUSION:The overall segmentation accuracy of this algorithm in the clinical data set is 97.08%,and the segmentation effect is superior to that of other competitive methods from the qualitative and quantitative perspectives.It is verified that the structural feature flow designed in this paper can extract more precise local details of tooth shape from coordinate and normal information by constructing an attention aggregation mechanism,and the spatial feature flow designed in this paper can ensure the robustness of the model to complex teeth such as missing teeth,dislocated teeth,and crowded dentition by constructing a transformation network(Tran Net).Therefore,this tooth segmentation algorithm is highly reliable for clinicians'practical reference.

Reliability of photogrammetry for evaluating pelvic posture in healthy individuals / 中国组织工程研究

BACKGROUND:In clinical practice,the anterior superior iliac spine and posterior superior iliac spine are usually located by palpation,and the tilt of the pelvis is determined by visual observation method or photogrammetry.Among them,the visual observation method can only have qualitative conclusions,and its reliability is poor.The photogrammetry is not only more convenient and fast,but also can give more accurate quantitative data,which is one of the best clinical evaluation methods.However,there are no studies on the reliability of pelvic posture assessment using photogrammetry in China. OBJECTIVE:To evaluate the pelvic posture by visual observation method and photogrammetry,and to compare the reliability level of the two methods to guide clinical application. METHODS:Forty-five healthy subjects were selected and red marks were made at the bilateral anterior superior iliac spine and posterior superior iliac spine.Pelvic posture was photographed from the front,back(coronal plane),left,and right(sagittal plane).The left and right pelvic tilt angles(α,β angles)were selected from the front and back views,which represented the angle between the bilateral anterior superior iliac spine line or the bilateral posterior superior iliac spine line and the horizontal line.The anterior and posterior pelvic tilt angles(γ,θ angles)were selected from the side view,which represented the angle between the ipsilateral anterior superior iliac spine and posterior superior iliac spine line and the horizontal plane,indicating the sagittal plane pelvic tilt.Evaluation methods included visual observation method and photogrammetry.Two evaluators independently evaluated the pelvic α,β,γ,θ angles using the visual observation method first,and then recorded the pelvic α,β,γ,θ angles using the photogrammetry.After a one-month interval,the visual observation method and photogrammetry were performed again,and the pelvic α,β,γ,θ angles were recorded.The intraclass correlation coefficients were used to analyze the data obtained from the two evaluation methods and the before-and-after measurements:0.90-0.99 as an excellent correlation,0.80-0.89 as a good correlation,0.70-0.79 as a moderate correlation,and≤0.69 as a poor correlation.The standard error of measurement and the minimal detectable change with 95%confidence intervals were calculated to evaluate the inter-rater and intra-rater reliability. RESULTS AND CONCLUSION:(1)The interrater intraclass correlation coefficients of the visual observation method and photogrammetry were as follows:anterior view:0.682 and 0.718,posterior view:0.513 and 0.867,left view:0.739 and 0.960,and right view:0.756 and 0.971.The visual observation method showed poor correlation between the anterior and posterior views and moderate correlation between the left and right views,while the photogrammetry showed moderate correlation for the anterior view,good correlation for the posterior view,and excellent correlation for the left and right views.The standard error values of measurement were as follows:anterior view:3.266 and 1.625,posterior view:4.278 and 1.763,left view:5.935 and 1.787,and right view:5.723 and 1.698.The minimal detectable change values with 95%confidence intervals were as follows:anterior view:9.053 and 4.504,posterior view:11.858 and 4.887,left view:16.451 and 4.953,and right view:15.863 and 4.707.(2)The interrater intraclass correlation coefficients of the visual observation method and photogrammetry were as follows:anterior view:0.452 and 0.723,posterior view:0.483 and 0.904,left view:0.518 and 0.955,and right view:0.657 and 0.968.The visual observation method showed poor correlation in all four directions,while the photogrammetry showed moderate correlation for the anterior view and excellent correlation for the other three directions.The standard error values of measurement were as follows:anterior view:5.651 and 1.610,posterior view:4.237 and 1.523,left view:7.322 and 1.891,and right view:6.509 and 1.781.The minimal detectable change values with 95%confidence intervals were as follows:anterior view:15.664 and 4.463,posterior view:11.744 and 4.222,left view:20.296 and 5.242,and right view:18.042 and 4.937.(3)These results confirm that the sagittal and coronal plane photogrammetries have good intrarater and interrater reliability for evaluating pelvic posture,especially with the use of the photogrammetry,which has good data stability.This method is simple,fast,efficient,accurate,low-cost,and does not cause X-ray damage,and can qualitatively and quantitatively reflect the actual situation of the patient's pelvis,making it suitable for clinical use.

An empirical study on the application of leadership evaluation indicator system for managers in primary medical institutions / 中华全科医师杂志

Objective:To evaluate the reliability and validity of a questionnaire assessing the leadership qualities of primary healthcare institution managers, and to further clarify the current state of leadership development among management teams of community health service centers in Shanghai.Methods:The study was a cross-sectional survey. It was conducted from August to December 2021, and used a stratified sampling method. Using a self-developed questionnaire for primary healthcare institution managers, we surveyed 279 individuals from 10 community health service centers in Shanghai, including management teams, middle-level cadres, general practitioners, and staff from health administrative departments in their respective districts. Leadership qualities were evaluated on five dimensions: inspiration, decisiveness, control, influence, and foresight. Cronbach′s α coefficient and split half coefficient were used to analyze the reliability of the questionnaire, and confirmatory factor analysis was used to assess the structural validity of the scale.Results:The overall Cronbach′s α reliability of the questionnaire for the comprehensive management of community health service centers was 0.96, and the Spearman-Brown split-half coefficient was 0.94. The validity analysis yielded a KMO value of 0.975, the RMSEA for factor analysis was 0.085, and the adaptation indexes all met the model adaptation conditions. Of the 279 participants, 174 were female (62.4%), 257 held a mid-level or higher professional title (92.1%). The overall leadership score of the community health service center management teams was (4.43±0.59), with the dimensions ranked from highest to lowest as follows: inspiration (4.52±0.55), decisiveness (4.46±0.62), control (4.44±0.60), influence (4.42±0.63), and foresight (4.32±0.69). The foresight score was significantly lower than the other four dimensions (all P<0.05). Conclusions:The questionnaire used to assess the leadership qualities of primary healthcare institution managers is reliable and valid. The development of leadership qualities among management teams of community health service centers in Shanghai is unbalanced, with foresight being the weakest dimension.
