Perturbações do comportamento alimentar em adolescentes e estilos de vida, sua relação com a percepção do auto-conceito e imagem corporal

Tendo como ponto de partida, o quadro conceptual esboçado a partir dos estudos revistos, procuramos nesta investigação analisar as perturbações do comportamento alimentar em adolescentes/estilos de vida, sua relação com a percepção do auto-conceito e imagem corporal. A amostra foi constituída por 405 alunos (232 do género feminino e 173 do género masculino) do ensino secundário (11º e 12º anos), com idades compreendidas entre os 15 e os 20 anos. Os participantes preencheram um questionário, dividido em 3 partes: sócio-demográfico/estilos de vida, escala sobre a percepção da imagem corporal – Relationship Between Body Image Percent Body Fat Among College Male Varsity Athletes and Non-athletes (Huddy, D. C.; Nieman, D. C. e Johnson, R. L. 1993 ) e escala da percepção do auto-conceito – The self-perception profile for college (Newman & Harter 1986). Neste estudo tivemos como principal objectivo, analisar as perturbações do comportamento alimentar/Índice de Massa Corporal a partir do impacto das variáveis psicológicas como: percepção do auto-conceito, imagem corporal, ambiente familiar, estilos de vida, numa amostra de adolescentes. A determinação do IMC mostra que a maioria dos adolescentes apresenta peso normal (71%). Apenas 14,3% apresentam excesso de peso, 3,2% tem obesidade moderada, 0,7%, obesidade grave e 0,5% obesidade mórbida. A avaliação baseada nas correlações entre as variáveis e entre as variáveis e as sub-escalas, revelaram que os adolescentes do género masculino apresentam uma média mais elevada a nível da percepção do auto-conceito do que o género feminino. Também uma percepção mais desfavorável do auto-conceito, está associada a um elevado índice de massa corporal. O grau de satisfação com o ambiente familiar revela uma mais favorável percepção do auto-conceito. Quanto à relação da percepção que os adolescentes têm relativamente ao auto-conceito e comportamentos afectos aos estilos de vida, há a ressaltar, que uma maior actividade física, está associada, a uma percepção menos favorável do auto-conceito. Os resultados evidenciam uma ausência de relações significativas entre a imagem corporal, o género e a idade. Também no nosso estudo não foi confirmada a hipótese de que a imagem corporal está correlacionada com o IMC. Em relação aos hábitos alimentares e IMC não foi possível comprovar esta hipótese, mas permitiu-nos conhecer alguns comportamentos alimentares.

Self-esteem mediates the relationship between connectedness to nature and body appreciation in women, but not men

Connectedness to nature (i.e., an affective and experiential connection to nature) is known to have a positive effect on psychological well-being, but its specific associations with body image have not been fully examined. To attend to this oversight, we conducted a preliminary investigation of associations between connectedness to nature and body appreciation. A total of 380 British adults completed measures of connectedness to nature, body appreciation, and self-esteem. Bivariate correlations revealed significant positive associations between all variables in women. In men, body appreciation was significantly correlated with self-esteem, but not connectedness to nature. Mediation analysis showed that, in women, self-esteem fully mediated the relationship between connectedness to nature and body appreciation. In men, body appreciation was significantly associated with self-esteem, but not connectedness to nature. These results point to a potential route for improving body image among women through connectedness to nature and self-esteem, but further research is necessary.

Translation and Psychometric Evaluation of a Standard Chinese Version of the Body Appreciation Scale-2

The present study examined the factorial and construct validity of a Standard Chinese translation of the Body Appreciation Scale (BAS-2; Tylka & Wood-Barcalow, 2015b). Participants were 191 women and 154 men from mainland China who were resident in Hong Kong at the time of recruitment. Results of confirmatory factor analysis indicated that the one-dimensional model of the BAS-2, in which all 10 items loaded onto the same factor, had adequate fit and was invariant across sex. Body appreciation scores had good internal consistency and were significantly correlated with self-esteem and life satisfaction, and, in women, with weight discrepancy and body mass index. There were no significant differences in body appreciation scores between women and men. The present findings suggest that the Standard Chinese translation of the BAS-2 has the same one-dimensional factor structure as its parent scale and may facilitate cross-cultural studies of positive body image.

Alimentação e saúde : uma abordagem epidemiológica de estudantes universitários

Resumo: A alimentação e o estado nutricional são factores determinantes do estado de saúde e sabe-se hoje que os mecanismos da patogénese de várias doenças crónicas não-transmissíveis podem ocorrer no início da idade adulta. A alimentação é influenciada por uma multiplicidade de factores, entre os quais se contam a importância atribuída à alimentação, o peso e imagem corporal e a percepção dos riscos associados à escolha de alimentos. Esta investigação teve como objectivos analisar, em estudantes universitários até aos 30 anos de idade, o estado nutricional, a importância atribuída a alimentação, as percepções do peso e da imagem corporal e a percepção do risco de doença relacionada com a alimentação. Os objectivos foram cumpridos através de dois desenhos de estudo distintos: estudo descritivo transversal e estudo de caso-controlo. Avaliou-se o peso, altura e os perímetros da cintura e da anca e construiu-se um questionário de auto-preenchimento para recolher a restante informação. Encontraram-se valores para a prevalência de obesidade e excesso de peso de, respectivamente, 6,5% e 24,3% e concluiu-se que existe uma percepção incorrecta do peso e da imagem corporal, mais frequente entre os indivíduos obesos. Os obesos também consideram a alimentação menos importante que os indivíduos normoponderais. A análise da percepção dos riscos revela que os inquiridos consideram que factores como a obesidade e a inactividade física são menos prejudiciais para a saúde do que factores como as alterações climáticas ou as radiações de telefones móveis. Verificaram-se também diferenças entre sexos nos parâmetros estudados: relativamente às mulheres, os homens sobrestimam mais frequentemente o peso e a imagem corporal, consideram a alimentação menos importante, julgam-se em menor risco de doença e classificam os factores de risco estudados como menos prejudiciais. Conclui-se que as estratégias de educação alimentar e de promoção da saúde devem considerar as diferenças registadas entre sexos e a importância atribuída à alimentação e as percepções do risco, do peso e da imagem corporal. Abstract: Nutrition and nutritional status are health determinants and it’s accepted that the mechanisms for the pathogenesis of several chronic non-communicable diseases can occur in early adult age. Nutrition is influenced by a large number of factors, including the value placed on food, weight and body image and the risk perception associated with food choice. Consequently, the analysis of the factors that can influence food behaviour and food choice in young adults can be useful for the control and prevention of nutrition related disease. The objectives of this research were to analyse, in college students up to 30 years of age, nutritional status, value placed on nutrition, weight and body image perceptions and the risk perception of nutrition related disease. Two study designs were used: cross-sectional and case-control. Weight, height and waist and hip circumference were measured and a questionnaire was built to collect the remaining information. Prevalences of 6,5% for obesity and 24,3% for excess weight were found, along with the existence of biased weight and body image perceptions, more frequent in obese subjects. Obese subjects also placed less value on nutrition than non-obese. Risk perception analysis shows that risk factors like obesity and physical inactivity are considered less hazardous than risk factors like climate changes and mobile phone radiation. Men, comparatively to women, overestimated more frequently their weight and body image, placed less value in nutrition, considered themselves less disease susceptible and classified the risk factors studied as less hazardous. The conclusions of this study show that nutrition education and health promotion strategies should consider the gender related differences reported and, also, the value placed on nutrition and weigh, body image and risk perceptions.

Early processing in the human lateral occipital complex is highly responsive to illusory contours but not to salient regions.

Human electrophysiological studies support a model whereby sensitivity to so-called illusory contour stimuli is first seen within the lateral occipital complex. A challenge to this model posits that the lateral occipital complex is a general site for crude region-based segmentation, based on findings of equivalent hemodynamic activations in the lateral occipital complex to illusory contour and so-called salient region stimuli, a stimulus class that lacks the classic bounding contours of illusory contours. Using high-density electrical mapping of visual evoked potentials, we show that early lateral occipital cortex activity is substantially stronger to illusory contour than to salient region stimuli, whereas later lateral occipital complex activity is stronger to salient region than to illusory contour stimuli. Our results suggest that equivalent hemodynamic activity to illusory contour and salient region stimuli probably reflects temporally integrated responses, a result of the poor temporal resolution of hemodynamic imaging. The temporal precision of visual evoked potentials is critical for establishing viable models of completion processes and visual scene analysis. We propose that crude spatial segmentation analyses, which are insensitive to illusory contours, occur first within dorsal visual regions, not the lateral occipital complex, and that initial illusory contour sensitivity is a function of the lateral occipital complex.

Risk-taking behaviours in adolescent boys and girls : sexuality and dietary health

This study examined adolescents' reported sexual and dietary health-risk behaviours and perceptions. Specifically, this study analyzed the data of 600 students (300 male~ 300 female) in grades 9, I 1, and OAC (mean, standard deviation). The mean age of the students in the sample is 16 with a standard deviation of 1.6. The study was a secondary analysis ofthe first-year data of a 3-year longitudinal study conducted by Youth Lifestyle Choices-Community University Research Alliance (YLC-CURA) on adolescents. To explore sexuality and dietary health, this study purposefully selected sections of the survey that represented sex and dieting behaviours of adolescents. Separate gender and age data analyses revealed different patterns among the variables. Specifically., findings revealed that adolescents who engaged in recent sexual activities were more likely to have a relatively more positive body image perception and were relatively more likely to engage in disordered eating. Across both genders and 3 age levels, adolescents reported that despite their unhealthy dietary habits they felt that dieting was not a high-risk behaviour. Results were discussed in terms of educational implication for sexual health programs.

Bullying in physical education : its prevalence & impact on the intention to continue secondary school physical education

The purpose of this study was to determine the prevalence of bullying in physical education and its influence on students' intention to participate in the class in the future. Additionally, the study researched the relationship between bullying and body image as well as bullying and physical competency in physical education. A survey was utilized that collected both quantitative and qualitative data about students' experiences in physical education. Two-hundred and thirty-four grade 10 students (144 female and 90 male) from 8 different secondary schools participated in the study. Data analyses were completed using the Statistical Package for the Social Sciences (SPSS) version 16.0. Results showed thaLapproximately 18.3% of respondents had .experienced physical bullying in physical education; 23.7% had experienced verbal bullying; and 20.4% experienced social bullying. Furthermore, those who experienced frequent bullying in physical education did not intend on taking the class in the future. The relationship between body image and bullying was not found to be significant. However, physical competence was found to significantly predict bullying in physical education. These results show how prevalent bullying is in physical education classes and how it negatively impacts future participation in the class.

Exploring Body-Related Experiences among Individuals with Spinal Cord Injury

Using modified constructivist grounded theory, the purpose of the present study was to explore body-related experiences, specifically body image, in people with spinal cord injury. A total of nine participants (five women, four men) who had a broad range of body image experiences (from very negative to very positive) were interviewed. Most participants explained experiencing a fluctuating body image that varied from day-to-day. Negative body image experiences were represented by appearance, weight concerns, and function with all body image experiences encompassed by self-presentational concerns and tactics (an unanticipated finding). Positive body image was represented by acceptance, appreciation and gratitude of the body. Interestingly, negative body image experiences were not found to be represented by the opposite of positive body image experiences as they were each distinct. These findings have direct implications for medical professionals in hospital and rehabilitation settings to understand the importance of body image after spinal cord injury.

Transition nutritionnelle et double fardeau de la malnutrition chez des adultes de Ouagadougou au Burkina Faso (Afrique de l’Ouest)

Cette étude s’inscrit dans le cadre du projet « Pôle francophone africain sur le Double Fardeau Nutritionnel » (DFN) du laboratoire TRANSNUT, centre collaborateur OMS sur la transition nutritionnelle du Département de Nutrition de l’Université de Montréal, en collaboration avec ses partenaires au Burkina Faso, à savoir l’Institut de Recherche en Sciences de la Santé (IRSS) et l’Institut Supérieur des Sciences de la Population (ISSP). Elle est l’une des premières à s’intéresser au double fardeau de la malnutrition en Afrique francophone. Cette étude avait pour objectif de démontrer l’existence du double fardeau de la malnutrition parmi les adultes de Ouagadougou au Burkina Faso, d’en donner l’ampleur et d’identifier ses liens avec les facteurs du mode de vie. Plus spécifiquement, elle visait à décrire les carences nutritionnelles, les facteurs de risque cardiométabolique (FRCM), et la typologie du double fardeau de la malnutrition; examiner les caractéristiques du mode de vie des adultes et leurs liens avec le double fardeau de la malnutrition selon les conditions économique, et enfin d’examiner l’association entre inflammation subclinique, les carences nutritionnelles et les FRCM selon les facteurs du mode de vie. Ces objectifs faisaient suite à nos principales hypothèses qui stipulaient que : parmi les adultes de Ouagadougou, le phénotype de double fardeau de la malnutrition le plus fréquemment observé est l’association de surpoids/obésité avec une ou plusieurs carences nutritionnelles, surtout chez les femmes, puis qu’une alimentation de piètre qualité, en lien avec de mauvaises conditions socioéconomiques et de vie est associée tant aux FRCM qu’aux carences nutritionnelles, contribuant ainsi au double fardeau de malnutrition, et enfin qu’un état d’inflammation subclinique joue un rôle de médiateur entre le mode de vie et aussi bien les carences nutritionnelles que les FRCM. Afin de répondre à ces objectifs, une étude transversale descriptive et analytique a été conduite auprès d’un échantillon aléatoire de 330 adultes âgés de 25 à 60 ans recrutés au sein de l’Observatoire de Population de Ouagadougou, situé à la partie nord de la ville. Cet échantillon a été subdivisé en terciles du score de possessions matérielles, proxy du statut socioéconomique, avec 110 personnes respectivement dans chaque strate de niveau socioéconomique bas, moyen et élevé. Chaque participant a fourni des données sociodémographiques, anthropométriques, cliniques et comportementales; il a aussi fourni un échantillon de sang. Les principales variables de l’étude étaient les suivantes : l’âge, les conditions socioéconomiques (insécurité alimentaire, éducation et proxy du revenu), le mode de vie (les apports alimentaires et la qualité de l’alimentation, l’activité physique, la consommation d’alcool et de tabac, la perception de l’image corporelle, le stress psychosocial); l’inflammation subclinique; les FRCM [surpoids/obésité, tension artérielle élevée (TAE) ou hypertension artérielle (HTA), hyperglycémie, dyslipidémie et insulino-résistance]; les carences nutritionnelles (maigreur, anémie, carence en fer et en vitamine A). Des phénotypes de double fardeau de la malnutrition ont été identifiés en combinant FRCM et carences nutritionnelles. Les résultats ont montré une prévalence élevée de surpoids/obésité, d’obésité abdominale, d’hypertension artérielle, d’hyperglycémie, de résistance à l’insuline et du taux de lipoprotéine de haute densité (HDL-C) bas, respectivement de 24,2 %, 12,5 %, 21,9 %, 22,3 %, 25,1 % et 30,0 %. En utilisant les seuils plus sensibles de la Fédération Internationale du Diabète (FID), l’obésité abdominale, la tension artérielle élevée (TAE), l’hyperglycémie était respectivement de 23,5 %; 36,1 % et 34,5 %. Des carences nutritionnelles étaient également présentes, l’anémie, la carence en fer et en vitamine A, ainsi que la maigreur atteignant respectivement 25,5 %, 15,4 %, 12,7 % et 9,7 % de la population étudiée. Les femmes étaient significativement plus touchées que les hommes autant par les FRCM que par les carences nutritionnelles. Le double fardeau de la malnutrition touchait 23,5 % des personnes et même 25,8 % avec les seuils de la FID pour l’obésité abdominale, la TAE, et l’hyperglycémie. Les deux principaux phénotypes observés étaient : l’association de « surpoids/obésité avec au moins une carence en micronutriment », touchant 7,8 % (11,8 % ♀ vs. 3,4 % ♂) des personnes et l’association d’au moins un FRCM autre que le surpoids/obésité avec au moins une carence en micronutriment, qui touchait 9.0 % (12,4 % ♀ vs. 5,4 % ♂) des personnes. La prévalence de ces phénotypes était plus élevée en utilisant les seuils de la FID plutôt que les seuils de l’OMS. Près de 72,9 % des personnes ou 81,2 % (seuils de la FID) avaient au moins un FRCM. Nous avons identifié à partir de l’analyse typologique, deux schémas alimentaires; « urbain » et « traditionnel », dans cette étude. Les carences nutritionnelles étaient davantage associées au schéma alimentaire « traditionnel », alors que les FRCM se retrouvaient dans les deux schémas alimentaires. Le schéma « urbain » regroupait significativement plus d’hommes et de personnes de niveau socioéconomique élevé, alors que les personnes de niveau socioéconomique bas et les femmes étaient proportionnellement plus nombreuses dans le schéma « traditionnel ». Le temps dévolu aux activités sédentaires était significativement plus important que celui consacré aux activités d’intensité modérée à vigoureuse. L’activité physique était inversement associée à l’indice de masse corporelle (IMC), au tour de taille (TT), à la masse grasse corporelle, à la tension artérielle systolique (TAS) et diastolique (TAD), à la triglycéridémie et au taux de lipoprotéine de faible densité (LDL-C). L’IMC et le TT augmentaient en outre avec le temps de sédentarité. Ainsi, le double fardeau de malnutrition était associé au statut socioéconomique bas, au sexe féminin et à la sédentarité. Nous avons aussi trouvé que 39,4 % des personnes avaient une inflammation subclinique qui était associée de façon indépendante et positive à la ferritinémie, à l’IMC, au TT et à la masse grasse corporelle, et négativement au HDL-C. L’exploration du stress psychosocial et de l’image corporelle a révélé une association entre le stress psychosocial, l’HTA et une perception positive de l’embonpoint. Les personnes ayant peut-être accusé un retard de croissance à l’enfance (d’après l’indice de Cormic) étaient significativement plus touchées par le surpoids/obésité, l’obésité abdominale et la résistance à l’insuline. Ces résultats nous ont permis d’atteindre nos objectifs, mais aussi de vérifier nos hypothèses de recherche. Comme on peut le constater, les FRCM sont une réalité à Ouagadougou, qui se compliquent par leur coexistence avec des carences en micronutriments dont la prévalence est tout aussi importante. Une transition nutritionnelle est en cours dans cette ville et contribue au bouleversement des comportements alimentaires et du style de vie favorisant l’émergence de ce double fardeau, dans un contexte où le passé nutritionnel de la population offre des conditions idéales pour un niveau de risque particulièrement élevé pour ces FRCM. Cependant, l’évolution de cette prévalence pourrait être inversée ou tout au moins ralentie si des actions étaient entreprises dès maintenant.

Les déterminants du comportement alimentaire de jeunes hommes gais

Introduction : Cette étude visait à explorer les déterminants des choix alimentaires de jeunes hommes gais. L’objectif secondaire était d’explorer la perception des hommes gais à l’égard du comportement alimentaire des hommes hétérosexuels. Méthode : Une méthode qualitative s’appuyant sur la prise de photographies et d’entrevues individuelles semi-dirigées a été utilisée. Résultats : Onze hommes gais de 21 à 25 ans et habitant en appartement dans la région de Montréal ont participé à l’étude. L’apparence corporelle, la santé et la nutrition sont des facteurs très influents de leur comportement alimentaire. Les hommes de la cohorte soutiennent la perception que ces facteurs n’influencent pas aussi fortement le comportement alimentaire des hommes hétérosexuels. Ils sont de grands consommateurs de cuisine hors domicile. Plusieurs d’entre eux limitent leur consommation de viande, un aliment qu’ils considèrent masculin et fortement lié aux hommes hétérosexuels. Conclusion : Le comportement alimentaire des jeunes hommes de cette cohorte est influencé par plusieurs facteurs qui ne sont habituellement pas associés aux hommes, dont l’apparence corporelle, la santé et la nutrition. Ils sont au fait de cette dichotomie en se comparant à leurs proches hétérosexuels. Si les professionnels de la santé négligent ces facteurs, ils risquent de passer à côté de leviers d’intervention efficaces.

Activité physique et insatisfaction de l'image corporelle chez un groupe d'adolescentes

Active regions for colour texture segmentation integrating region and boundary information

In this paper a colour texture segmentation method, which unifies region and boundary information, is proposed. The algorithm uses a coarse detection of the perceptual (colour and texture) edges of the image to adequately place and initialise a set of active regions. Colour texture of regions is modelled by the conjunction of non-parametric techniques of kernel density estimation (which allow to estimate the colour behaviour) and classical co-occurrence matrix based texture features. Therefore, region information is defined and accurate boundary information can be extracted to guide the segmentation process. Regions concurrently compete for the image pixels in order to segment the whole image taking both information sources into account. Furthermore, experimental results are shown which prove the performance of the proposed method

Impacto de la auto - percepción de imagen corporal en sujetos con VIH y lipoatrofia facial.

La lipoatrofia facial es uno de los efectos secundarios que con más frecuencia se presenta y afecta la calidad de vida del paciente con VIH que recibe tratamiento antiretroviral. Metodología: Estudio observacional de corte transversal que involucró 126 sujetos, a quienes se aplicó una encuesta semi-estructurada para determinar cómo percibe el paciente que la lipoatrofia facial lo afecta en áreas afectiva, social, laboral y ocupacional; evaluar la percepción de la imagen corporal; caracterizar sociodemográficamente; determinar la prevalencia de lipoatrofia facial y establecer si hay diferencias de percepción de la imagen corporal según la caracterización sociodemográfica. Resultados: La Prevalencia de lipoatrofia facial fue del 57.1%. El grado de satisfacción en cuanto a apariencia física tuvo un promedio de 5.01±2.69. El 88.7% y 80.3% de los pacientes evaluados sintieron tristeza y frustración con su apariencia respectivamente. El 53.5% y el 42.9% informaron menos oportunidades laborales y educativas. La orientación sexual reportada con mayor frecuencia fue homosexualidad. No hubo diferencias estadísticamente significativas entre el grado de satisfacción de apariencia con aspectos sociodemográficos excepto en pacientes que recibieron apoyo psicológico. Conclusión: Primer estudio en el país que evalúa el impacto de la lipoatrofia facial en pacientes con VIH y tratamiento antiretroviral. Aunque la presencia de lipoatrofia facial sobre la cotidianidad no es estadísticamente significativa, si resulta trascendental pues existen porcentajes importantes de emociones y alteraciones psicológicas que afectan directamente a estos sujetos en las áreas afectiva, social, laboral y ocupacional. Se hace necesaria la realización de más estudios que permitan obtener mayor de evidencia.

Shape complexity based on mutual information

Shape complexity has recently received attention from different fields, such as computer vision and psychology. In this paper, integral geometry and information theory tools are applied to quantify the shape complexity from two different perspectives: from the inside of the object, we evaluate its degree of structure or correlation between its surfaces (inner complexity), and from the outside, we compute its degree of interaction with the circumscribing sphere (outer complexity). Our shape complexity measures are based on the following two facts: uniformly distributed global lines crossing an object define a continuous information channel and the continuous mutual information of this channel is independent of the object discretisation and invariant to translations, rotations, and changes of scale. The measures introduced in this paper can be potentially used as shape descriptors for object recognition, image retrieval, object localisation, tumour analysis, and protein docking, among others

Imagem corporal e fatores de risco em praticantes de caminhada da cidade do Natal-RN

Body image is the figure of our bodies built in our minds and the degree of dissatisfaction is often associated with risk factors identified by anthropometric measures. The purpose of this descriptive study was to evaluate the risk factors associated to morphological and functional variables associate to the perception of auto-image in middle-aged walkers of the south zone of the city of Natal. A hundred and thirty volunteers had been evaluated in four groups in function of the gender and age group. As measurement evaluations were used an auto-image perception questionnaire proposed by Stunkart of nine silhouettes numbered for both gender was applied; a weighing machine equipped with stadiometer for the body mass (kg) and stature (m) and the body mass index (kg/m2) that was calculated with base in measures of the body weight and stature and classified according to norms of the National Institute of Health (2000) as well as the systolic and diastolic blood pressure by a electronic digital device (DIGITRONIC). A metal anthropometric tape was used for the waist to hip ratio (WHR). It was used Analyses of variance (ANOVA) one-way, post hoc of Tukey and correlation of Spearman for the nonparametric data adopting the level of ρ≤ 0,05 for rejection of the null hypothesis. The body mass index indicated high factors of risk in the consisting groups. In all the groups were registered the desire to reduce their silhouettes. The body weight shows reduced when compared with the younger group in the male group of superior age group, while in the female group the inverse one occurs. The autoimage perception is associated with the classification of the waist to hip ratio in the female gender in the age group of the 50 to the 59 years and in the classification of the body mass index of all constituted groups. Significant associations had not been found for classification of the systolic and diastolic blood pressure in relation to the auto-image 41 perception. This thesis presents relation of interdisciplinarity and its contents have application in the fields of Physical Education, Medicine, Physiotherapy and Nursing
