As imagens do envelhecimento e as práticas idadistas em Cuidados de Saúde Primários: implicações na actividade física dos idosos

RESUMO: O envelhecimento demográfico tem vindo a aumentar em todo o mundo. Porém, constata-se que os últimos anos de vida são, frequentemente, acompanhados de situações de incapacidade que poderiam ter sido prevenidas. Apesar da importância da actividade física na saúde, verifica-se que uma grande proporção de idosos são sedentários, aumentando o risco de incapacidade. Os profissionais de saúde podem ser influenciados por imagens negativas relativas ao envelhecimento. Tal pode conduzir a práticas de discriminação, com repercussão na forma como os idosos se vêem a si próprios e, consequentemente, no seu comportamento na prática de actividade física. Este estudo tem como objectivo analisar o modo como as imagens do envelhecimento e dos idosos, bem como as práticas idadistas percebidas pelos idosos no contacto com profissionais de saúde influenciam a sua prática de actividade física. Realizou-se um estudo qualitativo, com recurso à entrevista semi-estruturada e de associação livre das palavras, sendo entrevistados 18 utentes que recorreram a um Centro de Saúde. Pelos resultados, constatou-se que uma parte considerável dos participantes (n=8) mencionou que a forma como são vistos pelos profissionais de saúde e como estes lidam consigo influencia a sua prática de actividade física. A imagem mais referida como favorecendo esta prática foi o facto de se considerarem pessoas com vontade de viver. Como principal prática favorecedora identificou-se o aconselhamento/educação para a saúde. A imagem mais mencionada como dificultando a actividade física foi a de os idosos serem deprimidos/tristes/aborrecidos e rabugentos/teimosos. As práticas mais identificadas como dificultando a actividade física foram: o desinteresse face aos problemas de saúde; o não encaminhamento para intervenções adequadas às necessidades; a indicação de que o problema de saúde é devido à idade, não o sendo; a postura autoritária em que só o profissional decide a opção terapêutica; e a verbalização de que o utente já tem muita idade para realizar uma actividade. Conclui-se que as imagens negativas do envelhecimento e dos idosos bem como a existência de práticas idadistas por parte dos profissionais de saúde, condicionam de forma negativa a prática de actividade física nos idosos.---------------ABSTRACT: The aging population has been increasing around the world. However, it appears that the last years of life are often accompanied by situations of disability, which could have been prevented. Despite the importance of physical activity on health, it appears that a large proportion of elderly people are sedentary, increasing the risk of disability. Health professionals may be influenced by negative images related to aging and that may lead to discriminatory practices with repercussion in how older people see themselves and thus their behavior as related to physical activity. This study aims to examine how the images concerning aging and older people, as well as ageist practices perceived by older people in contact with health professionals, do influence their physical activity. A qualitative study was conducted using a semi-structured interview and techniques of free word association. Eighteen primary care elderly users were interviewed. A considerable proportion of the sample (n=8) mentioned that the way health professionals see them and deal with them influences their level of physical activity. The image that most favoured this practice was that people are willing to live. Counseling/health education was identified as the main favouring practice. The image which was most often mentioned as hindering physical activity was that of elderly as being depressed, sad or bored, and grumpy or stubborn.The practices most often identified as hindering physical activity were: lack of interest regarding health problems; non-referral to appropriate intervention needs; indicating that the health problem is due to age, not being the case; authoritarian professional attitudes regarding who decides the treatment options; verbalization that the user is already to old to perform an activity. This study concludes that the negative images of aging and older people as well the existence of ageist practices by health professionals negatively affect the practice of physical activity in the elderly.

Sudden cardiac arrest associated with early repolarization.

BACKGROUND: Early repolarization is a common electrocardiographic finding that is generally considered to be benign. Its potential to cause cardiac arrhythmias has been hypothesized from experimental studies, but it is not known whether there is a clinical association with sudden cardiac arrest. METHODS: We reviewed data from 206 case subjects at 22 centers who were resuscitated after cardiac arrest due to idiopathic ventricular fibrillation and assessed the prevalence of electrocardiographic early repolarization. The latter was defined as an elevation of the QRS-ST junction of at least 0.1 mV from baseline in the inferior or lateral lead, manifested as QRS slurring or notching. The control group comprised 412 subjects without heart disease who were matched for age, sex, race, and level of physical activity. Follow-up data that included the results of monitoring with an implantable defibrillator were obtained for all case subjects. RESULTS: Early repolarization was more frequent in case subjects with idiopathic ventricular fibrillation than in control subjects (31% vs. 5%, P<0.001). Among case subjects, those with early repolarization were more likely to be male and to have a history of syncope or sudden cardiac arrest during sleep than those without early repolarization. In eight subjects, the origin of ectopy that initiated ventricular arrhythmias was mapped to sites concordant with the localization of repolarization abnormalities. During a mean (+/-SD) follow-up of 61+/-50 months, defibrillator monitoring showed a higher incidence of recurrent ventricular fibrillation in case subjects with a repolarization abnormality than in those without such an abnormality (hazard ratio, 2.1; 95% confidence interval, 1.2 to 3.5; P=0.008). CONCLUSIONS: Among patients with a history of idiopathic ventricular fibrillation, there is an increased prevalence of early repolarization.

Influencia de la temperatura en la ingesta de pacientes hospitalizados.

BACKGROUND AND OBJECTIVES Prevalence of hyponutrition in hospitalized patients is very high and it has been shown to be an important prognostic factor. Most of admitted patients depend on hospital food to cover their nutritional demands being important to assess the factors influencing their intake, which may be modified in order to improve it and prevent the consequences of inadequate feeding. In previous works, it has been shown that one of the worst scored characteristics of dishes was the temperature. The aim of this study was to assess the influence of temperature on patient's satisfaction and amount eaten depending on whether the food was served in isothermal trolleys keeping proper food temperature or not. MATERIAL AND METHODS We carried out satisfaction surveys to hospitalized patients having regular diets, served with or without isothermal trolleys. The following data were gathered: age, gender, weight, number of visits, mobility, autonomy, amount of orally taken medication, intake of out-of-hospital foods, qualification of food temperature, presentation and smokiness, amount of food eaten, and reasons for not eating all the content of the tray. RESULTS Of the 363 surveys, 134 (37.96%) were done to patients with isothermal trays and 229 (62.04%) to patients without them. Sixty percent of the patients referred having eaten less than the normal amount within the last week, the most frequent reason being decreased appetite. During lunch and dinner, 69.3% and 67.7%, respectively, ate half or less of the tray content, the main reasons being as follows: lack of appetite (42% at lunch time and 40% at dinner), do not like the food (24.3 and 26.2%) or taste (15.3 and 16.8%). Other less common reasons were the odor, the amount of food, having nausea or vomiting, fatigue, and lack of autonomy. There were no significant differences in the amount eaten by gender, weight, number of visits, amount of medication, and level of physical activity. The food temperature was classified as adequate by 62% of the patients, the presentation by 95%, and smokiness by 85%. When comparing the patients served with or without isothermal trays, there were no differences with regards to baseline characteristics analyzed that might have had an influence on amount eaten. Ninety percent of the patients with isothermal trolley rated the food temperature as good, as compared with 57.2% of the patients with conventional trolley, the difference being statistically significant (P = 0.000). Besides, there were differences in the amount of food eaten between patients with and without isothermal trolley, so that 41% and 27.7% ate all the tray content, respectively, difference being statistically significant (P = 0.007). There were no differences in smokiness or presentation rating. CONCLUSIONS Most of the patients (60%) had decreased appetite during hospital admission. The percentage of hospitalized patients rating the food temperature as being good is higher among patients served with isothermal trolleys. The amount of food eaten by the patients served with isothermal trolleys is significantly higher that in those without them.

Free-living energy expenditure assessed by two different methods in rural Gambian men.

OBJECTIVE: To assess total free-living energy expenditure (EE) in Gambian farmers with two independent methods, and to determine the most realistic free-living EE and physical activity in order to establish energy requirements for rural populations in developing countries. DESIGN: In this cross-sectional study two methods were applied at the same time. SETTING: Three rural villages and Dunn Nutrition Centre Keneba, MRC, The Gambia. SUBJECTS: Eight healthy, male subjects were recruited from three rural Gambian villages in the sub-Sahelian area (age: 25 +/- 4y; weight: 61.2 +/- 10.1 kg; height: 169.5 +/- 6.5 cm, body mass index: 21.2 +/- 2.5 kg/m2). INTERVENTION: We assessed free-living EE with two inconspicuous and independent methods: the first one used doubly labeled water (DLW) (2H2 18O) over a period of 12 days, whereas the second one was based on continuous heart rate (HR) measurements on two to three days using individual regression lines (HR vs EE) established by indirect calorimetry in a respiration chamber. Isotopic dilution of deuterium (2H2O) was also used to assess total body water and hence fat-free mass (FFM). RESULTS: EE assessed by DLW was found to be 3880 +/- 994 kcal/day (16.2 +/- 4.2 MJ/day). Expressed per unit body weight the EE averaged 64.2 +/- 9.3 kcal/kg/d (269 +/- 38 kJ/kg/d). These results were consistent with the EE results assessed by HR: 3847 +/- 605 kcal/d (16.1 +/- 2.5 MJ/d) or 63.4 +/- 8.2 kcal/kg/d (265 +/- 34kJ/kg/d). Physical activity index, expressed as a multiple of basal metabolic rate (BMR), averaged 2.40 +/- 0.41 (DLW) or 2.40 +/- 0.28 (HR). CONCLUSIONS: These findings suggest an extremely high level of physical activity in Gambian men during intense agricultural work (wet season). This contrasts with the relative food shortage, previously reported during the harvesting period. We conclude that the assessment of EE during the agricultural season in non-industrialized countries needs further investigations in order to obtain information on the energy requirement of these populations. For this purpose the use of the DLW and HR methods have been shown to be useful and complementary.

Adherence to statin treatment and associated factors in female users from the Unified Health System (SUS)

Objective: To identify the adherence rate of a statin treatment and possible related factors in female users from the Unified Health System. Method: Seventy-one women were evaluated (64.2 ± 11.0 years) regarding the socio-economic level, comorbidities, current medications, level of physical activity, self-report of muscular pain, adherence to the medical prescription, body composition and biochemical profile. The data were analyzed as frequencies, Chi-Squared test, and Mann Whitney test (p<0.05). Results: 15.5% of women did not adhere to the medical prescription for the statin treatment, whose had less comorbidities (p=0.01), consumed less quantities of medications (p=0.00), and tended to be younger (p=0.06). Those patients also presented higher values of lipid profile (CT: p=0.01; LDL-c: p=0.02). Musculoskeletal complains were not associated to the adherence rate to the medication. Conclusion: The associated factors to adherence of dyslipidemic women to statin medical prescription were age, quantity of comorbidities and quantity of current medication.


Esport extraescolar i la utilització de les TIC i els jocs electrònics modifiquen la força de prensió de la mà?

L'objectiu del nostre estudi va ser conèixer si l'esport extraescolar i el temps dedicat setmanalment a les tecnologies de la informació i la comunicació (TIC) i jocs electrònics, tenen influència en el desenvolupament de la força de prensió de la mà i avantbraç en nens entre els 14 i 16 anys. Es va realitzar un estudi observacional de disseny transversal. La població objecte d'estudi van ser 39 nens de segon cicle de l'ESO. L'activitat física extraescolar i el temps dedicat setmanalment a les TIC i als jocs electrònics es van recollir mitjançant qüestionaris. Es va utilitzar el test d'handgrip per a la valoració de la força màxima voluntària de la mà i avantbraç del costat dominant. L'edat i la força de la mà dominant estan associades de forma estadísticament significativa, la força màxima voluntària (F=5,86; p=0,006) i el valor mig de la força sostinguda per sobre del 60% (F=4,5; p=0,02). A l'analitzar el grau d'activitat física (Kcal/setmana) respecte a la força màxima voluntària (r= 0,07; p= 0,716) i força sostinguda per sobre del 60% (r= 0,30; p= 0,09) observem una associació feble positiva i no estadísticament significativa. Si analitzem les hores setmanes TIC en relació a la força màxima voluntària observem una associació molt feble i no estadísticament significativa. La força de prensió de la mà en escolars està relacionada de forma positiva i estadísticament significativa amb l'edat i el pes corporal. No es relaciona amb el nivell d'activitat física i les hores dedicades a les TIC.

The daily energy expenditure in stable chronic obstructive pulmonary disease.

Resting energy expenditure is frequently increased in chronic obstructive pulmonary disease (COPD), but it is unknown if this hypermetabolism holds true over 24 h. The aim of this study was to measure the actual 24-h energy expenditure (24-h EE) in patients with stable COPD. Energy expenditure was measured by indirect calorimetry, using a metabolic chamber for 24-h EE and a canopy for basal metabolic rate (BMR). Physical activity was detected in the chamber by a radar system, and its duration was quantified. Two groups matched for age and height were studied: 16 male ambulatory patients with stable COPD and 12 male normal subjects. Body weight was 92 +/- 12% of ideal body weight in the group with COPD and 108 +/- 11% in the control group (p = 0.01). BMR was 120 +/- 7% of predicted in the group with COPD and 108 +/- 12% in the control group (p < 0.01). However, 24-h EE was similar in the two groups, amounting to 1,935 +/- 259 kcal in patients with COPD and 2,046 +/- 253 kcal in the control group (NS). This corresponded to 145% and 137% of predicted BMR, and to 121% and 126% of measured BMR in patients with COPD and the control group, respectively (NS). Patients were allowed to pursue their usual treatment within the chamber, and a positive correlation existed between 24-h EE and the daily dose of inhaled beta 2-agonists (p < 0.03). During daytime, physical activity was lower in patients with COPD. This study shows that patients with stable COPD are characterized by a normal daily energy expenditure in controlled conditions in spite of an increased basal metabolic rate. They appear to save energy by reducing their spontaneous level of physical activity.

Étude de l’impact d’un programme d’activité physique (Amazone) auprès de femmes en traitement pour un cancer du sein

Le cancer du sein est la forme de cancer la plus souvent diagnostiquée chez les femmes. Elles doivent vivre avec des séquelles qui nuisent à leur qualité de vie. Plusieurs études ont montré les bienfaits de l’activité physique (AP) sur les composantes physiques et psychologiques des patientes. Toutefois, elles réduisent souvent leur pratique d'AP suite aux traitements en raison de la détérioration de leur condition physique. Or, le maintien à long terme de la pratique d’AP est essentiel pour en conserver les bénéfices. La première section du mémoire présente une recension des écrits sur les bienfaits de l’AP auprès des femmes atteintes d'un cancer du sein et la seconde rend compte d'une étude expérimentale ayant pour objectif d'évaluer l’impact d’un programme d’AP sur le sentiment d’efficacité personnel et sur le plaisir associé à la pratique d'AP. Une enquête de suivi a été menée trois mois après la fin du programme afin d’évaluer le maintien à long terme de la pratique d'AP. L'étude a été réalisée auprès de 18 patientes en cours de traitement. Le groupe expérimental a suivi un programme supervisé d’AP combiné à des séances de counseling sur une période de 16 semaines. Le groupe témoin avait la possibilité de suivre un programme de yoga. Nos résultats indiquent une amélioration statistiquement significative des trois composantes mesurées, soit le sentiment d'efficacité personnelle, le plaisir à faire de l'AP et le maintien de la pratique après la participation au programme.
