Atividade física no lazer e transtornos mentais comuns entre idosos residentes em um município do nordeste do Brasil

OBJETIVO: Analisar a associação entre atividade física no lazer e a prevalência de transtornos mentais comuns entre idosos. MÉTODOS: Estudo transversal com amostra constituída de 562 indivíduos residentes no município de Feira de Santana, 69,6% do sexo feminino e 30,4% do sexo masculino, com média de idade de 68,93 ± 7,05 anos. Foi utilizado um formulário com informações sociodemográficas, doenças referidas, triagem para transtornos mentais comuns (TMC) utilizando o Self-Reporting Questionnaire (SRQ-20). Participação em atividade física no lazer foi avaliada segundo autopercepção do tipo e da intensidade da atividade (leve, moderada ou pesada). Para análise estatística, foi utilizada a técnica de regressão logística, com o cálculo das razões de prevalência, intervalo de confiança (95%) e nível de significância p < 0,05. RESULTADOS: Dentre os indivíduos estudados, 18,3% foram classificados como ativos no lazer. A prevalência de TMC foi de 32,1%, sendo menor entre os indivíduos ativos no lazer (RP = 0,49; IC = 0,29-0,84), após ajuste por faixa etária e renda. CONCLUSÃO: Há elevada proporção de inativos no lazer, e essa condição está associada à maior prevalência de TMC. Sugere-se que ações direcionadas à saúde mental priorizem programas que favoreçam o incentivo à prática de atividade física entre os idosos residentes no município, tendo em vista a contribuição desse comportamento no tratamento e na prevenção de morbidades psíquicas.

Prevalência e fatores associados aos transtornos mentais comuns em residentes médicos e da área multiprofissional

OBJETIVO: Determinar a prevalência de transtornos mentais comuns (TMC) e sua associação a fatores sociodemográficos e profissionais em residentes de medicina, enfermagem, nutrição e saúde coletiva da cidade do Recife (PE). MÉTODOS: Estudo transversal foi conduzido, em 2007, envolvendo uma amostra aleatória de 178 residentes que responderam a questões sociodemográficas e sobre a formação profissional e ao Self-Reporting Questionnaire (SRQ-20). Calcularam-se as prevalências de TMC e estimaram-se as razões de prevalência (RP) e os intervalos de confiança. RESULTADOS: A prevalência total dos TMC foi de 51,1% e não se observou associação aos fatores sociodemográficos. A prevalência do evento foi 39% maior nos médicos que nos não médicos (p = 0,049) e 46% maior em residentes médicos das especialidades cirúrgicas que entre os de enfermagem, nutrição e saúde coletiva (p = 0,048). Cinco das queixas do SRQ-20 foram mais frequentes no sexo feminino (p < 0,05). CONCLUSÃO: Os dados demonstram a elevada magnitude dos TMC nessa população, principalmente nos residentes médicos, e servem para educadores e gestores de serviços de saúde no sentido de viabilizar estratégias para prevenir e recuperar a qualidade de vida dos residentes.

Barcoding human physical activity to assess chronic pain conditions.

BACKGROUND: Modern theories define chronic pain as a multidimensional experience - the result of complex interplay between physiological and psychological factors with significant impact on patients' physical, emotional and social functioning. The development of reliable assessment tools capable of capturing the multidimensional impact of chronic pain has challenged the medical community for decades. A number of validated tools are currently used in clinical practice however they all rely on self-reporting and are therefore inherently subjective. In this study we show that a comprehensive analysis of physical activity (PA) under real life conditions may capture behavioral aspects that may reflect physical and emotional functioning.¦METHODOLOGY: PA was monitored during five consecutive days in 60 chronic pain patients and 15 pain-free healthy subjects. To analyze the various aspects of pain-related activity behaviors we defined the concept of PA 'barcoding'. The main idea was to combine different features of PA (type, intensity, duration) to define various PA states. The temporal sequence of different states was visualized as a 'barcode' which indicated that significant information about daily activity can be contained in the amount and variety of PA states, and in the temporal structure of sequence. This information was quantified using complementary measures such as structural complexity metrics (information and sample entropy, Lempel-Ziv complexity), time spent in PA states, and two composite scores, which integrate all measures. The reliability of these measures to characterize chronic pain conditions was assessed by comparing groups of subjects with clinically different pain intensity.¦CONCLUSION: The defined measures of PA showed good discriminative features. The results suggest that significant information about pain-related functional limitations is captured by the structural complexity of PA barcodes, which decreases when the intensity of pain increases. We conclude that a comprehensive analysis of daily-life PA can provide an objective appraisal of the intensity of pain.

Real-life versus package insert: a post-marketing study on adverse-event rates of the virosomal hepatitis A vaccine Epaxal® in healthy travellers.

There are various methods to collect adverse events (AEs) in clinical trials. The methods how AEs are collected in vaccine trials is of special interest: solicited reporting can lead to over-reporting events that have little or no biological relationship to the vaccine. We assessed the rate of AEs listed in the package insert for the virosomal hepatitis A vaccine Epaxal(®), comparing data collected by solicited or unsolicited self-reporting. In an open, multi-centre post-marketing study, 2675 healthy travellers received single doses of vaccine administered intramuscularly. AEs were recorded based on solicited and unsolicited questioning during a four-day period after vaccination. A total of 2541 questionnaires could be evaluated (95.0% return rate). Solicited self-reporting resulted in significantly higher (p<0.0001) rates of subjects with AEs than unsolicited reporting, both at baseline (18.9% solicited versus 2.1% unsolicited systemic AEs) and following immunization (29.6% versus 19.3% local AEs; 33.8% versus 18.2% systemic AEs). This could indicate that actual reporting rates of AEs with Epaxal(®) may be substantially lower than described in the package insert. The distribution of AEs differed significantly between the applied methods of collecting AEs. The most common AEs listed in the package insert were reported almost exclusively with solicited questioning. The reporting of local AEs was more likely than that of systemic AEs to be influenced by subjects' sex, age and study centre. Women reported higher rates of AEs than men. The results highlight the need for detailing the methods how vaccine tolerability was reported and assessed.

Agravos à saúde, hipertensão arterial e predisposição ao estresse em motoristas de caminhão

O estudo investigou agravos à saúde que predispõem ao estresse com o uso do Self Reporting Questionnaire (SRQ-20) que avalia possíveis transtornos mentais comuns não psicóticos e identificar a associação com a hipertensão arterial. A amostra foi de 258 motoristas profissionais de transporte de cargas em uma rodovia brasileira (37,5±10,0 anos), 55% ingeriam bebidas alcoólicas, 37% com hipertensão arterial e 57% referiram já ter usado remédios para manter estado de alerta. Os motoristas referiram sentirem-se nervosos, tensos ou preocupados (56%), dormirem mal (47%), dores de cabeça (37%), terem dificuldade de tomar decisões (38%) e dificuldade de pensar com clareza (20%). Obteve-se como resultados que 33% eram portadores de possíveis transtornos mentais comuns e houve associação (p<0,05) com referência de cansaço, diminuição da concentração, considerar-se nervoso ou estressado, ter problemas pessoais ou no trabalho e transportar carga de horário. Não houve associação com hipertensão arterial. Conclui-se que foi expressiva a presença de prováveis transtornos mentais comuns provavelmente decorrentes das condições estressantes de trabalho.

Work-related stress according to the demand-control model and minor psychic disorders in nursing workers

This was a cross-sectional study that aimed to assess the association between work-related stress according to the Demand-Control Model, and the occurrence of Minor Psychic Disorder (MPD) in nursing workers. The participants were 335 professionals, out of which 245 were nursing technicians, aged predominantly between 20 and 40 years. Data were collected using the Job Stress Scale and the Self-Reporting Questionnaire-20. The analysis was performed using descriptive and analytical statistics. The prevalence of suspected MPD was 20.6%. Workers classified in the quadrants active job and high strain of the Demand-Control Model presented higher potential for developing MPD compared with those classified in the quadrant low strain. In conclusion, stress affects the mental health of workers and the aspects related to high psychological demands and high control still require further insight in order to understand their influence on the disease processes of nursing workers.

Residual antimalarials in malaria patients from Tanzania--implications on drug efficacy assessment and spread of parasite resistance.

Repeated antimalarial treatment for febrile episodes and self-treatment are common in malaria-endemic areas. The intake of antimalarials prior to participating in an in vivo study may alter treatment outcome and affect the interpretation of both efficacy and safety outcomes. We report the findings from baseline plasma sampling of malaria patients prior to inclusion into an in vivo study in Tanzania and discuss the implications of residual concentrations of antimalarials in this setting. In an in vivo study conducted in a rural area of Tanzania in 2008, baseline plasma samples from patients reporting no antimalarial intake within the last 28 days were screened for the presence of 14 antimalarials (parent drugs or metabolites) using liquid chromatography-tandem mass spectrometry. Among the 148 patients enrolled, 110 (74.3%) had at least one antimalarial in their plasma: 80 (54.1%) had lumefantrine above the lower limit of calibration (LLC = 4 ng/mL), 7 (4.7%) desbutyl-lumefantrine (4 ng/mL), 77 (52.0%) sulfadoxine (0.5 ng/mL), 15 (10.1%) pyrimethamine (0.5 ng/mL), 16 (10.8%) quinine (2.5 ng/mL) and none chloroquine (2.5 ng/mL). The proportion of patients with detectable antimalarial drug levels prior to enrollment into the study is worrying. Indeed artemether-lumefantrine was supposed to be available only at government health facilities. Although sulfadoxine-pyrimethamine is only recommended for intermittent preventive treatment in pregnancy (IPTp), it was still widely used in public and private health facilities and sold in drug shops. Self-reporting of previous drug intake is unreliable and thus screening for the presence of antimalarial drug levels should be considered in future in vivo studies to allow for accurate assessment of treatment outcome. Furthermore, persisting sub-therapeutic drug levels of antimalarials in a population could promote the spread of drug resistance. The knowledge on drug pressure in a given population is important to monitor standard treatment policy implementation.

Daily smoking as a marker of weight control practices among female adolescents

Purpose: There is evidence indicating that adolescent females smoke as a way to control weight. The aim of our research is to assess whether daily smoking is a marker for weight control practices among adolescent females. Methods: Data were drawn from the 2002 Swiss Multicenter Adolescent Survey on Health (SMASH02) data base, a survey including 7,548 [3,838 females] in-school adolescents aged 16-20 years in Switzerland. Among females self-reporting BMI (N _ 3,761), two groups were drawn: daily smokers (DS, N _ 1,273) included all those smoking at least 1 cigarette/day and never smokers (NS, N _ 1,888) included all those having never smoked. Former (N _ 177) and occasional (N _ 423) smokers were not included. Groups were compared on weight control practices (being on a diet, self-induced vomiting, use of doctor-prescribed or over-the-counter appetite suppressors) controlling for possible confounding variables (age, BMI, feeling fat, body image, use of other substances, depression, sport practice, academic track and perceived advanced puberty). Analyses were performed with STATA 9. Bivariate analyses are presented as point-prevalence and multivariate analysis (using logistic regression) are presented as adjusted odds ratio (AOR) and [95% confidence interval]. Results: In the bivariate analysis, DS females were significantly more likely (p _ 0.001) than NS to be on a diet (DS: 33.2%, NS: 22.2%), to self-induce vomiting (DS: 9.0%, NS: 3.3%), and to use doctor prescribed (DS: 2.3%, NS: 0.9%) or over-the-counter (DS: 3.2%, NS: 1.2%) appetite suppressors. In the multivariate analysis, DS females were more likely than NS to be on a diet (AOR: 1.40 [1.17/1.68]), to self-induce vomiting (AOR: 2.07 [1.45/2.97]), and to use doctor-prescribed appetite suppressors (AOR: 1.99 [1.00/ 3.96]). Conclusions: Weight control practices are more frequent among female daily smokers than among never smokers. This finding seems to confirm cigarette smoking as a way to control weight among adolescent females. Health professionals should inquire adolescent female smokers about weight control practices, and this association must be kept in mind when discussing tobacco cessation options with adolescent females. Sources of Support: The SMASH02 survey was funded by the Swiss Federal Office of Public Health and the participating cantons.

Transitoriness in cancer patients: a cross-sectional survey of lung and gastrointestinal cancer patients.

Despite earlier diagnosis and advancements in treatment, cancer remains a leading cause of death in the world (13% of all deaths according to the World Health Organization) among men and women. Cancer accounts for approximately 20% of the deaths in the USA every year. Here, we report the findings from a cross-sectional survey of psychosocial factors in lung and gastrointestinal cancer patients. The aim of the study was to explore the associations among transitoriness, uncertainty, and locus of control (LOC) with quality of life. Transitoriness is defined as a person's confrontation with life's finitude due to a cancer diagnosis. A total of 126 patients with lung or gastrointestinal cancer completed eight self-reporting questionnaires addressing demographics, spiritual perspective, symptom burden, transitoriness, uncertainty, LOC, and quality of life. Transitoriness, uncertainty, and LOC were significantly associated with one another (r = 0.3267, p = 0.0002/r = 0.1994, p = 0.0252, respectively). LOC/belief in chance has a significant inverse relationship with patients' quality of life (r = -0.2505, p = 0.0047). Transitoriness, uncertainty, and LOC were found to have a significant inverse relationship with patients' quality of life (transitoriness state: r = -0.5363, p = 0.0000/trait: r = -0.4629, p = 0.0000/uncertainty: r = -0.4929, p = 0.0000/internal LOC: r = 0.1759, p = 0.0489/chance LOC: r = -0.2505, p = 0.0047). Transitoriness, uncertainty, and LOC are important concepts as they adversely influence patients' quality of life. Incorporating this finding into the care of cancer patients may provide them with the support they need to cope with treatment and maintenance of a positive quality of life.

Transtornos psiquiátricos menores e procura por cuidados em estudantes de Medicina

A carreira médica pode desencadear alterações patológicas na saúde mental, que podem ter início já na graduação. O objetivo deste estudo foi identificar a prevalência de Transtornos Psiquiátricos Menores (TPMe) e a procura por ajuda em estudantes de um curso de Medicina. Trata-se de um estudo transversal, com uma população de 343 estudantes da primeira à quarta série, maiores de 18 anos. Foram realizadas entrevistas, em salas de aula, por meio de dois questionários estruturados, o Self Reporting Questionnaire (SRQ-20) e outro elaborado pelos autores. Análises descritiva, univariada, bivariada e estatística foram utilizadas mediante o programa Microsoft Excel. Os resultados evidenciaram que, entre os acadêmicos com TPMe, 41,6% (a maioria) moravam sozinhos e 75% eram mulheres. Entre os acometidos, 59,2% não conheciam qualquer programa e apenas 9,1% procuraram ajuda. O uso de medicamento foi duas vezes mais prevalente em mulheres com TPMe do que em homens, sendo antidepressivos e ansiolíticos os mais usados. A prevalência de 26,1% de TPMe nos alunos, associada a baixa procura por cuidados e a relatos de automedicação, demonstra a inefetividade dos atuais programas de apoio.

Transtornos mentais menores entre estudantes de medicina

OBJETIVO: O objetivo do estudo foi estimar a prevalência de Transtornos Mentais Menores (TMM) entre os estudantes do curso de Medicina da Universidade Federal da Paraíba (UFPB) e avaliar possíveis correlações entre TMM e fatores de risco. MÉTODOS: Estudo transversal realizado de abril a agosto de 2012 com 384 alunos do curso de Medicina. O questionário utilizado foi autoaplicável e anônimo. Foram coletados dados sociodemográficos e a rede de apoio social. Para o rastreamento de TMM, utilizou-se o Self-Reporting Questionnaire (SRQ-20). RESULTADOS: A prevalência total de TMM encontrada foi de 33,6%, que esteve independentemente associada ao período do curso (p < 0,001; 9,7% a 63,3%), à idade (p < 0,05; 25% a 42,6%), a não seguir uma religião (p < 0,05; 44,8%). CONCLUSÃO: Os dados demonstram elevada prevalência de TMM nessa população e a importância de subsidiar ações para prevenção e cuidado com a saúde mental dos estudantes de Medicina, melhorando sua qualidade de vida.

Evaluation of common mental disorders in women with polycystic ovary syndrome and its relationship with body mass index

PURPOSE: To evaluate the prevalence of common mental disorders in women diagnosed with polycystic ovary syndrome as compared with paired controls without this syndrome. METHODS: Cross-sectional study with a Control Group examining women between the ages of 18 and 30 who did not use antidepressants and who sought the Gynecology Service of the researched sites. For every woman diagnosed with the polycystic ovary syndrome, another with the same age, educational status and presence or absence of sexual partners was sought without this diagnosis. In total, 166 patients agreed to participate, consisting of 95 diagnosed with polycystic ovary syndrome and 71 in the Control Group. The diagnosis of polycystic ovary syndrome was made by the presence of two from three criteria: oligomenorrhea or amenorrhea, clinical or biochemical hyperandrogenism and polycystic ovaries on transvaginal ultrasound, following exclusion of patients with Cushing's syndrome, congenital adrenal hyperplasia, and androgen-secreting tumors. Weight and height were measured to calculate the body mass index. The Self-Reporting Questionnaire, which evaluated 20 items, was used as an indicator of common mental disorders. A χ² analysis stratified by the category of body mass index was used to compare the prevalence of common mental disorders, between the groups of women with and without the polycystic ovary syndrome. RESULTS: There were no significant differences in age, education, presence of sexual partners, ethnicity, socioeconomic status, use of psychiatric medication, and search for consultation in mental health between the studied groups. The prevalence of obese women with indications of common mental disorders was significantly higher in women with polycystic ovary syndrome than in the Control Group. In the group with healthy body mass index, the incidence of common mental disorders was statistically significant different between women with polycystic ovary syndrome and normal controls (p=0.008). CONCLUSIONS: Women with diagnosis of this disease have an almost three-fold increased likelihood of common mental disorders as compared with those without polycystic ovary syndrome. Although obesity is often observed in polycystic ovary syndrome, even women with a healthy body mass index have an increased risk of psychiatric comorbidity.

Chance of psychiatric morbidity amongst recently diagnosed cancer outpatients attending a chemotherapy unit

The prevalent rate of psychiatry morbidity amongst patients with cancer reported in various studies ranges from 5 to 50%, a variation that can be attributed to differences in sample size, the disease itself and treatment factors. The objectives of the present study were to determine the frequency of psychiatric morbidity amongst recently diagnosed cancer outpatients and try to identify which factors might be related to further psychological distress. Two hundred and eleven (70.9%) female patients and 87 (29.1%) male patients from the chemotherapy unit of the Cancer Hospital A.C. Camargo (São Paulo) completed a questionnaire that featured data on demographic, medical and treatment details. The Self Reporting Questionnaire (SRQ-20) was administered to the patients to determine their personal psychiatric morbidity. Seventy-two patients (25.8%) scored > or = 8 in the SRQ-20, the cut-off point for a patient to be considered a psychiatric case. When the low and high scoring groups were compared no differences were detected regarding age, marital status, tumor site, sex, or previous treatment. Nonetheless, patients in the lowest social class and those who were bedridden less than 50% of the time had a significantly higher probability of being a psychiatric case. Regarding help-seeking behavior in situations in which they had doubts or were frightened, about 64% of the total sample did not seek any type of support and did not talk to anyone. This frequency of psychiatric morbidity agrees with data from the cancer literature. According to many investigators, the early detection of a comorbid psychiatric disorder is crucial to relieve a patient's suffering.

Facteurs environnementaux et symptômes des troubles oculaires et cutanés chez les enfants de moins de cinq ans : cas des zones de l’Observatoire de population de Ouagadougou

Les risques liés à l’environnement immédiat, notamment le manque d’accès à l’eau potable, à l’assainissement, à un logement décent et à un milieu de vie sain constituent un des facteurs à l’origine de la mauvaise santé des enfants de moins de cinq ans dans les pays en développement. Les objectifs principaux poursuivis dans cette recherche sont de mesurer l’influence de ces risques de l’environnement immédiat sur la prévalence des symptômes des troubles oculaires et celle des symptômes des troubles cutanés chez les enfants de moins de cinq ans à Ouagadougou et de rechercher les autres déterminants sous-jacents de la prévalence de ces symptômes dans cette ville. Nous utilisons les données de l’enquête réalisée en février 2010 sur l’état de santé et le comportement sanitaire associé aux maladies et symptômes récents et les données sur les événements démographiques et sur les conditions de vie des ménages collectées en mai 2009 durant le round 1 de l’enquête ménage. L’échantillon de l’étude est constitué de 950 enfants issus de 736 ménages sélectionnés aléatoirement dans cinq quartiers périphériques de la ville de Ouagadougou. Nous avons recouru à l’analyse descriptive fondée sur les tableaux croisés et les tests du chi-2, et à l’analyse de la régression logistique multivariée ayant permis d’étudier les risques relatifs de la survenue desdits symptômes. L’analyse descriptive montre que certaines variables de l’environnement immédiat, en l’occurrence le mode d’évacuation des ordures ménagères, le type de toilette utilisé le plus souvent par la plupart des membres du ménage et le type de quartier de résidence, sont associés à la prévalence des troubles oculaires. Mais une analyse approfondie à l’aide de la régression logistique multivariée n’a confirmé que l’effet du type de quartier de résidence. Concernant la prévalence des symptômes des troubles cutanés, en analyse bi-variée, les variables de l’environnement immédiat qui y sont associées sont la nature du sol intérieur et le mode d’évacuation des eaux usées. L’analyse multivariée semble confirmer les effets de ces variables. Nous avons relevé quelques limites des données utilisées, notamment la faible taille de l’échantillon, la non-confirmation par voie médicale des données sanitaires et le caractère transversal desdites données. Toutefois, les résultats trouvés pourront être utiles aux planificateurs et décideurs qui ont la charge de la gestion de l’espace urbain dans le but de mieux concevoir de nouvelles politiques urbaines mettant l’accent sur la restructuration des quartiers précaires afin de mieux combattre les maladies évitables. En conclusion, en tenant compte des limites relevées, il serait utile de procéder à d’autres investigations afin de tirer des conclusions moins sujettes à débat du point de vue méthodologique.

L’association entre la marche utilitaire et le diabète : une étude transversale des adultes montréalais

Contexte: Le diabète de type 2 est un problème de santé publique important. La pratique régulière de l’activité physique contribue à la prévention de cette maladie chronique. Toutefois, peu de recherches portent sur l’association entre l’activité physique de transport, notamment la marche utilitaire, et le diabète. Objectif : L’objectif de cette étude est d’examiner l’association entre la présence d’un diagnostic de diabète de type 2 et les pratiques de marche utilitaire dans un échantillon transversal. Méthode : Cette étude est une analyse secondaire de données provenant d’un projet de recherche sur l’implantation d’un système de vélos libre-service. 7012 adultes ont été recrutés par téléphone au printemps 2009, à l’automne 2009 et à l’automne 2010. La marche utilitaire a été mesurée en utilisant des questions adaptées du International Physical Activity Questionnaire (IPAQ). L’association entre la marche utilitaire et le diabète auto-rapporté a été examinée au moyen d’analyses de régression logistique multivariées. L’influence des variables socio- démographiques, du niveau d’activité physique autre et de l’indice de masse corporelle a été contrôlée. Des analyses de sensibilité ont aussi été faites, utilisant un seuil différent pour le temps de marche utilitaire. Résultats : Dans le modèle final, la marche utilitaire est associée à une prévalence du diabète plus faible (RC=0,721; IC 95% : 0,547-0,950). Conclusion: La pratique de la marche utilitaire est associée à une prévalence plus faible de diabète auto-rapporté. La promotion de ce type d’activité physique aurait sa place dans la prévention du diabète dans une perspective de santé publique.
