Falls Among The Elderly: Risk Factors In A Population-based Study.

The aim of the present study was to identify factors associated with the occurrence of falls among elderly adults in a population-based study (ISACamp 2008). A population-based cross-sectional study was carried out with two-stage cluster sampling. The sample was composed of 1,520 elderly adults living in the urban area of the city of Campinas, São Paulo, Brazil. The occurrence of falls was analyzed based on reports of the main accident occurred in the previous 12 months. Data on socioeconomic/demographic factors and adverse health conditions were tested for possible associations with the outcome. Prevalence ratios (PR) were estimated and adjusted for gender and age using the Poisson multiple regression analysis. Falls were more frequent, after adjustment for gender and age, among female elderly participants (PR = 2.39; 95% confidence interval (95% CI) 1.47 - 3.87), elderly adults (80 years old and older) (PR = 2.50; 95% CI 1.61 - 3.88), widowed (PR = 1.74; 95% CI 1.04 - 2.89) and among elderly adults who had rheumatism/arthritis/arthrosis (PR = 1.58; 95% CI 1.00 - 2.48), osteoporosis (PR = 1.71; 95% CI 1.18 - 2.49), asthma/bronchitis/emphysema (PR = 1,73; 95% CI 1.09 - 2.74), headache (PR = 1.59; 95% CI 1.07 - 2.38), mental common disorder (PR = 1.72; 95% CI 1.12 - 2.64), dizziness (PR = 2.82; 95% CI 1.98 - 4.02), insomnia (PR = 1.75; 95% CI 1.16 - 2.65), use of multiple medications (five or more) (PR = 2.50; 95% CI 1.12 - 5.56) and use of cane/walker (PR = 2.16; 95% CI 1.19 - 3,93). The present study shows segments of the elderly population who are more prone to falls through the identification of factors associated with this outcome. The findings can contribute to the planning of public health policies and programs addressed to the prevention of falls.

Variables Associated With The Performance Of Centers For Dental Specialties In Brazil.

The aim of this study was to evaluate the performance of the Centers for Dental Specialties (CDS) in the country and associations with sociodemographic indicators of the municipalities, structural variables of services and primary health care organization in the years 2004-2009. The study used secondary data from procedures performed in the CDS to the specialties of periodontics, endodontics, surgery and primary care. Bivariate analysis by χ2 test was used to test the association between the dependent variable (performance of the CDS) with the independents. Then, Poisson regression analysis was performed. With regard to the overall achievement of targets, it was observed that the majority of CDS (69.25%) performance was considered poor/regular. The independent factors associated with poor/regular performance of CDS were: municipalities belonging to the Northeast, South and Southeast regions, with lower Human Development Index (HDI), lower population density, and reduced time to deployment. HDI and population density are important for the performance of the CDS in Brazil. Similarly, the peculiarities related to less populated areas as well as regional location and time of service implementation CDS should be taken into account in the planning of these services.

Equity Of Access To Pap Smears: Population-based Study In Campinas, São Paulo, Brazil.

To determine the prevalence of the Papanicolaou exam among women aged 20 to 59 years in the city of Campinas (state of São Paulo, Brazil) and to analyze associations between this test and affiliation to private health insurance plans as well as socioeconomic/demographic variables and health-related behavior. To do so, a population-based, cross-sectional study was carried out. Statistical analyses took the study design into account. Despite the significant socioeconomic differences between women with and without private health plans, no differences between these groups were found regarding having been submitted to the Papanicolaou test. In fact no differences were found as to socioeconomic and health variables analyzed. Among all variables analyzed, only marital status was significantly associated with having undergone the test. The Brazilian public health system accounted for 55.7% of the exams. The present findings indicate social equity in the city of Campinas regarding the preventive exam for cervical cancer in the age group studied.

Burnout Syndrome In Nursing Assistants Of A Public Hospital In The State Of São Paulo.

The burnout syndrome is a psychosocial phenomenon that arises as a response to chronic interpersonal stressors present at work. There are many aspects that make nursing assistants vulnerable to chronic stress situations that may lead to burnout, highlighting the low degree of autonomy in the healthcare staff and spending more in direct contact with patients. To assess the prevalence of the burnout syndrome in nursing assistants in a public hospital, as well as its association with socio-demographic and professional variables. A socio-demographic and professional questionnaire and the Maslach Burnout Inventory (MBI-SS) were applied to 534 nursing assistants. The prevalence of burnout syndrome among nursing assistants was 5.9%. High emotional exhaustion was observed in 23.6%, 21.9% showed high depersonalization, and 29.9% low professional achievement. It was found statistically significant associations between emotional exhaustion, job sector and marital status; depersonalization, having children and health problems; low professional achievement and job sector and number of jobs. There was association between job satisfaction and the three dimensions. Professionals working in the health area must pay intense and extended attention to people who are dependent upon others. The intimate contact of the nursing assistants with hard-to-handle patients, as well as being afraid to make mistakes in healthcare are additional chronic stress factors and burnout syndrome cases related in this study.

Changing patterns of coronary heart disease in the hunter region of New South Wales, Australia

A population-based observational study of men acid women aged 35-69 years in the Hunter Region of New South Wales, Australia, was conducted to assess the impact. of risk-factor modification and increased drug therapy on the trends in major coronary events and case fatality. From 1985 to 1993, there were 3006 coronary deaths and 6450 nonfatal major coronary events. Rates of death and nonfatal myocardial infarction declined, but there was an increase in hospital admissions for prolonged chess pain. Reductions in cigarette smoking, diastolic blood pressure, total cholesterol, and increased use of aspirin can fully explain the 3.3% (95% confidence interval [CI] 2.4, 4.2) average annual reduction in rates of major coronary events for men and the 4.1% (95% CI 2.7, 5.5) reduction for women. In contrast, increased use of aspirin, beta-blockers, fibrinolytic therapy, and angiotensin-converting enzyme inhibitors explain less than hall of the 8.9% (95% CI 5.9, 11.8) and 6.9% (95% CI 2.7, 10.9) average annual reduction in case fatality in hospital for men and women, respectively. These trends suggest a decline in severity of coronary heart disease consistent with reductions in risk-factor levels and improved acute medical treatment. J CLIN EPIDEMIOL 52;8:761-771, 1999.

Marijuana Smoking and the Risk of Head and Neck Cancer: Pooled Analysis in the INHANCE Consortium

Background: Marijuana contains carcinogens similar to tobacco smoke and has been suggested by relatively small studies to increase the risk of head and neck cancer (HNC). Because tobacco is a major risk factor for HNC, large studies with substantial numbers of never tobacco users could help to clarify whether marijuana smoking is independently associated with HNC risk. Methods: We pooled self-reported interview data on marijuana smoking and known HNC risk factors on 4,029 HNC cases and 5,015 controls from five case-control studies within the INHANCE Consortium. Subanalyses were conducted among never tobacco users (493 cases and 1,813 controls) and among individuals who did not consume alcohol or smoke tobacco (237 cases and 887 controls). Results: The risk of HNC was not elevated by ever marijuana smoking [odds ratio (OR), 0.88; 95% confidence intervals (95% Cl), 0.67-1.16], and there was no increasing risk associated with increasing frequency, duration, or cumulative consumption of marijuana smoking. An increased risk of HNC associated with marijuana use was not detected among never tobacco users (OR, 0.93; 95% Cl, 0.63-1.37; three studies) nor among individuals who did not drink alcohol and smoke tobacco (OR, 1.06; 95% Cl, 0.47-2.38; two studies). Conclusion: Our results are consistent with the notion that infrequent marijuana smoking does not confer a risk of these malignancies. Nonetheless, because the prevalence of frequent marijuana smoking was low in most of the contributing studies, we could not rule out a moderately increased risk, particularly among subgroups without exposure to tobacco and alcohol.

Interaction between Tobacco and Alcohol Use and the Risk of Head and Neck Cancer: Pooled Analysis in the International Head and Neck Cancer Epidemiology Consortium

Background: The magnitude of risk conferred by the interaction between tobacco and alcohol use on the risk of head and neck cancers is not clear because studies have used various methods to quantify the excess head and neck cancer burden. Methods: We analyzed individual-level pooled data from 17 European and American case-control studies (11,221 cases and 16,168 controls) participating in the International Head and Neck Cancer Epidemiology consortium. We estimated the multiplicative interaction parameter (psi) and population attributable risks (PAR). Results: A greater than multiplicative joint effect between ever tobacco and alcohol use was observed for head and neck cancer risk (psi = 2.15; 95% confidence interval, 1.53-3.04). The PAR for tobacco or alcohol was 72% (95% confidence interval, 61-79%) for head and neck cancer, of which 4% was due to alcohol alone, 33% was due to tobacco alone, and 35% was due to tobacco and alcohol combined. The total PAR differed by subsite (64% for oral cavity cancer, 72% for pharyngeal cancer, 89% for laryngeal cancer), by sex (74% for men, 57% for women), by age (33% for cases < 45 years, 73% for cases > 60 years), and by region (84% in Europe, 51% in North America, 83% in Latin America). Conclusions: Our results confirm that the joint effect between tobacco and alcohol use is greater than multiplicative on head and neck cancer risk. However, a substantial proportion of head and neck cancers cannot be attributed to tobacco or alcohol use, particularly for oral cavity cancer and for head and neck cancer among women and among young-onset cases.

A Sex-Specific Association between a 15q25 Variant and Upper Aerodigestive Tract Cancers

Background: Sequence variants located at 15q25 have been associated with lung cancer and propensity to smoke. We recently reported an association between rs16969968 and risk of upper aerodigestive tract (UADT) cancers (oral cavity, oropharynx, hypopharynx, larynx, and esophagus) in women (OR = 1.24, P = 0.003) with little effect in men (OR = 1.04, P = 0.35). Methods: In a coordinated genotyping study within the International Head and Neck Cancer Epidemiology (INHANCE) consortium, we have sought to replicate these findings in an additional 4,604 cases and 6,239 controls from 10 independent UADT cancer case-control studies. Results: rs16969968 was again associated with UADT cancers in women (OR = 1.21, 95% CI = 1.08-1.36, P = 0.001) and a similar lack of observed effect in men [OR = 1.02, 95% CI = 0.95-1.09, P = 0.66; P-heterogeneity (P(het)) = 0.01]. In a pooled analysis of the original and current studies, totaling 8,572 UADT cancer cases and 11,558 controls, the association was observed among females (OR = 1.22, 95% CI = 1.12-1.34, P = 7 x 10(-6)) but not males (OR = 1.02, 95% CI = 0.97-1.08, P = 0.35; P(het) = 6 x 10(-4)). There was little evidence for a sex difference in the association between this variant and cigarettes smoked per day, with male and female rs16969968 variant carriers smoking approximately the same amount more in the 11,991 ever smokers in the pooled analysis of the 14 studies (P(het) = 0.86). Conclusions: This study has confirmed a sex difference in the association between the 15q25 variant rs16969968 and UADT cancers. Impact: Further research is warranted to elucidate the mechanisms underlying these observations. Cancer Epidemiol Biomarkers Prev; 20(4); 658-64. (C) 2011 AACR.

Estado nutricional e estilo de vida em vegetarianos e onívoros, Grande Vitória-ES

Objetivo: Descrever e analisar o estado nutricional e aspectos do estilo de vida de vegetarianos e onívoros residentes na Grande Vitória/ES, na faixa etária de 35 a 64 anos de idade. Material E Métodos: Trata-se de estudo observacional híbrido de casos prevalentes com avaliação retrospectiva da exposição. Os grupos de expostos (134) e não expostos à dieta onívora típica ocidental (67) foram determinados no início da investigação. Foram coletados dados antropométricos, bioquímicos, de atividade física e alimentação através de questionário e 3 recordatórios de 24 horas e diagnosticados sobrepeso, Razão Cintura Quadril (RCQ) inadequada e hipercolesterolemia. Colesterol total e frações, triglicerídeos, ácido úrico, sódio e potássio urinários foram comparados entre os grupos, através do teste t de Student. Foi usado o teste qui-quadrado para comparar proporções, com =0,05. Resultados: Foram encontradas diferenças significativas em relação à ocupação. Duração da atividade física e tempo assistindo televisão e/ou utilizando computador foram maiores entre os onívoros. Os vegetarianos relataram práticas alimentares mais saudáveis e menor consumo de lipídios, proteínas e sódio. Os onívoros apresentaram maior risco de sobrepeso, RCQ inadequada e hipercolesterolemia (valores de P<0,0001). HDL-colesterol não foi diferente nos grupos. Conclusão: Os vegetarianos apresentaram perfil nutricional mais adequado e menor risco para os agravos crônicos estudados, apesar de pequena diferença no padrão de atividade física regular entre os grupos estudados.

Prevalencia de quedas de idosos em situacao de fragilidade

OBJETIVO: Analisar a prevalência de quedas em idosos frágeis, suas consequências e fatores demográficos associados. MÉTODOS: Estudo epidemiológico e transversal com amostra probabilística de 240 idosos em Ribeirão Preto, SP. A coleta de dados foi realizada no período de novembro de 2010 a fevereiro de 2011. Foi aplicado questionário que incluiu dados sociodemográficos, avaliação de quedas e a Escala de Fragilidade de Edmonton. Foram realizadas análises uni e bivariada. RESULTADOS: A média de idade foi de 73,5 (dp=:8,4) anos, maior no sexo feminino; 25% dos entrevistados tinham idade ≥ 80 anos; 11,3% apresentaram fragilidade moderada e 9,6% fragilidade severa. A prevalência de quedas no idoso frágil foi de 38,6%, maior no sexo feminino e nos idosos mais jovens (60 a 79 anos); 26,8% sofreram de uma a duas quedas, 27,1% ocorreram no dormitório, 84,7% caíram da própria altura, 55,9% apresentaram alteração do equilíbrio, 54,2% sofreram escoriações e 78% apresentaram medo de sofrer nova queda; houve maior chance de queda no idoso frágil 1,973 (1,094;3,556) quando comparado ao não frágil. CONCLUSÕES: É necessária a abordagem da saúde do idoso frágil, principalmente quanto ao risco de quedas, maior investimento nas estratégias de prevenção dessas síndromes e na formação de recursos humanos preparados para melhor atender essa população.

Classe social: conceitos e esquemas operacionais em pesquisa em saude

Discute-se a utilização do conceito de classe em pesquisas em saúde, as diferentes abordagens sociológicas de estratificação social e de estrutura de classes, o potencial explicativo do conceito em estudos de determinação social e desigualdades em saúde, os modelos de operacionalização elaborados para uso em pesquisas sociológicas, demográficas ou de saúde e os limites e possibilidades desses modelos. Foram destacados quatro modelos de operacionalização: de Singer para estudo da distribuição de renda no Brasil, adaptado por Barros para uso em pesquisas epidemiológicas; de Bronfman & Tuirán para o censo demográfico mexicano, adaptado por Lombardi et al para pesquisas epidemiológicas; de Goldthorpe para estudos socioeconômicos ingleses, adaptado pela Sociedade Espanhola de Epidemiologia; e o modelo de Wright para pesquisa em sociologia e ciência política, também usado em inquéritos populacionais em saúde. Em conclusão, conceitualmente cada um dos modelos apresentados é coerente com a concepção teórica que os embasam, mas não há como optar por qualquer deles, descartando os demais.

Fatores associados aos sintomas depressivos em idosos: estudo EpiFloripa

OBJETIVO Analisar a prevalência e fatores associados a sintomas depressivos em idosos. MÉTODOS Estudo epidemiológico transversal e de base domiciliar (inquérito EpiFloripa Idoso) com 1.656 idosos, realizado por conglomerados em dois estágios, setores censitários e domicílios, em Florianópolis, SC. A prevalência de sintomas depressivos (desfecho) foi obtida por meio da Geriatric Depression Scale (GDS-15), e testadas associações segundo variáveis sociodemográficas, de saúde, comportamentais e sociais. Foram calculadas razões de prevalências brutas e ajustadas com intervalo de 95% de confiança por regressão de Poisson. RESULTADOS A prevalência de sintomas depressivos foi de 23,9% (IC95% 21,84;26,01). Os fatores de risco associados no modelo final foram: escolaridade de cinco a oito anos (RP = 1,50; IC95% 1,08; 2,08), um a quatro anos (RP = 1,62; IC95% 1,18; 2,23) e nenhum ano de estudo (RP = 2,11; IC95% 1,46;3,05); situação econômica pior quando comparada com a que tinha aos 50 anos (RP = 1,33; IC95% 1,02;1,74); déficit cognitivo (RP = 1,45; IC95% 1,21;1,75); percepção de saúde regular (RP = 1,95; IC95% 1,47;2,60) e ruim (RP = 2,64; IC95% 1,82;3,83); dependência funcional (RP = 1,83; IC95% 1,43; 2,33); e dor crônica (RP = 1,35; IC95% 1,10;1,67). Grupo etário de 70 a 79 anos (RP = 0,77; IC95% 0,64;0,93); atividade física de lazer (RP = 0,75; IC95% 0,59;0,94); participação em grupos de convivência ou religiosos (RP = 0,80; IC95% 0,64;0,99); e ter relação sexual (RP = 0,70; IC95% 0,53;0,94) mostraram-se fatores protetores ao aparecimento dos sintomas depressivos. CONCLUSÕES Situação clínica adversa, desvantagem socioeconômica e pouca atividade social e sexual mostraram-se associadas aos sintomas depressivos em idosos.
