El déficit de vitamina B12 y ácido fólico en la población mayor de 65 años: estudio descriptivo

Introduction

The aim of this study is to establish the prevalence of vitamin B12 and folic acid deficiency in the population of 65 years and over in semi-urban and rural area, as well as investigating the risk factors, and the determining factors of this deficiency in this population and its relationship with the prevalence of concomitant cardiovascular and cognitive diseases.

Materials and methods

A cross-sectrionall study conducted in the Geriatrics Outpatients in the period between 2008 and 2010. Demographic, clinical and laboratory were collected at 3 different times.A bivariate analysis was performed with lack of vitamin B12 and folic acid, as the outcome variables.

Results

Vitamin B12 defieciency was found in 16.5% of the sample, and no folic acid deficiency. A strong association was found with vitamin B12 deficiency and cardiac and cerebrovascular diseases, vascular risk factors and drugs administered in prevention of cardiac events and ischaemic stroke.

Conclusions

There was a higher prevalence of vitamin B12 deficiency in the elderly population in the catchment area of Medina del Campo compared to that found in the literature, but not so with the isolated deficiency of folic acid.     

Presencia y representación de las personas mayores en la publicidad televisiva: el caso español

Introduction

The demographic shift towards aging population generates a series of socioeconomic and cultural changes that are beginning to transform the role and public image of older people. The elderly have become one of the market segments with a greater future. This fact has attracted little scientific interest in the field of advertising communication and for this reason there is little research that is actually looking into this Spain. This research examines the use that is made of the image of the elderly in the television advertising in Spain, looking at the differences between the advertisement dedicated to the targeting people over 65, and those that are not directed at the elderly, but use older people in their content as actors or main characters in the advertisement.

Material and methods

A content analysis study was conducted on a sample of 2,065 spots obtained from prime time slots (from 20:30 to 22:30 p.m.) from the five major Spanish television channels (TVE 1, La 2, Tele 5, Antena 3 and Cuatro). Two independent judges coded all the advertisements. The reliability coefficient between judges was 0.91.

Results and conclusions

In general, older people, particularly women, are not very often shown in Spanish advertising. Their presence is much stronger and visible in campaigns which aim their communication strategy at different age groups. In those cases, advertising presents the elderly with a stereotyped, self-interested and traditional image.     

Impacto del apoyo familiar en la presencia de quejas depresivas en personas mayores de Santiago de Chile

Introduction

Epidemiological changes can have an effect on social and, and in particular, family ties, which are important elements in the mental health of older people. The objective of this study was to evaluate the impact of family support on depressive disorders in older people of the community.

Material and methods

Face to face interviews were conducted on a representative sample of adults 60 years and older, living in urban area of Santiago de Chile. The information on depressive disorders was related to family composition, emotional and instrumental support, presence of conflict, health self-perception, functionality and self-efficiency. Data were analyzed using logistic regression models.

Results

From a total of 394 participants, 62% females, mean age 74 years (SD=8.1), 16% felt depressed almost every day. Depressive disorders were significantly associated in regression models with impaired self-perception of health and efficacy, lower instrumental support, and with the presence of conflict. The variable that most contributed to the model was self-rated poor health, increasing the odds of depressive disorders by 3.2.

Conclusions

Poor perception of health was the main determining factor for depressive complaints in older people, followed by lower family support, specifically instrumental support, and the presence of conflict. This information can help future programs in order to improve the quality of life in older people.     

Adaptación y validación de la versión española de la escala de evaluación de dolor en personas con demencia avanzada: PAINAD-Sp

Introduction

Pain in elderly people is considered a major concern in nursing home facilities affecting between 49% and 83% of the residents. Progression of Alzheimer's Disease causes more communication difficulties in patients with advanced dementia and therefore more problems to understand even the most simple pain evaluation scales. Identification and implementation of appropriate pain management strategies depends on an adequate pain assessment.

Material and methods

The main objective of the study was to validate the Spanish version of the PAINAD Scale (PAINAD-Sp) and to assess its applicability in Spanish Geriatric Nursing Homes. The 20 patients diagnosed with severe dementia from a Geriatric Centre in Spain were observed by five observers with different professional profiles for 5 minutes to each participant, and PAINAD-Sp Scale was administered simultaneously to a Visual Analogical Scale-VAS. Three different observational conditions were established: resting condition, during presumably pleasant activity and during presumable painful activity.

Results

Cronbach's alpha ranged between 0.467 and 0.827 (average 0.692), and rose if Breathing item was deleted. Inter-rater reliability ranged between 0.587 and 0.956. Correlation between PAINAD-Sp Scale total measures and VAS was statistically significant (P<.05) in all measures and ranged from 0.517 to 0.868.

Conclusions

Findings in the study showed that the scale is useful to measure pain in non communicative patients suffering from dementia. The scale maintains good levels of reliability for different healthcare professionals even when they have little training.     

Fragilidad como predictor de episodios adversos en estudios epidemiológicos: revisión de la literatura

Several epidemiological studies have analyzed the association between frailty status and adverse geriatric health outcomes, with there being a clear relationship being demonstrated in mortality, disability, mobility loss, institutionalization and falls. However, different studies have evaluated different number of these adverse events, with different criteria, and with different follow-up periods. As a result of this relationship, the objective of geriatric medicine must not only be the prevention, diagnosis and treatment of diseases based on multidisciplinary team work and use of geriatric units according to functional status of patients, but the detection, prevention and treatment of frailty. Frailty must be considered as a pre-disability state that can be prevented and treated to delay its progression towards disability, institutionalization, and death. The characterization of frailty status can also help other medical specialties to stratify the risk of adverse health outcomes in oncology treatments, surgical interventions, or diagnostic procedures.     

Problemas de seguridad relacionados con la aplicación de dispositivos de restricción física en personas mayores

The use of physical restraint devices on frail elderly could have significant negative consequences on their health. Apart from complications due to prolonged immobility, the use of this procedure is associated with other serious adverse effects which occur when a person is restricted in a position which carries a risk of asphyxiation. The devices most implicated in these incidents are bedrails, vests and restraining belts. Physical restraint could also be associated as much with the sudden death of patients, due to the stress that it causes, as with injuries from falling. This article presents the recommendations which experts, manufacturers and institutions dealing with the quality of health care have issued for the safest use of this procedure. It stresses the need for better training of professionals, as well as the importance of investigating the factors which can lead to accidents with the aim of preventing them.     

Desarrollo de un instrumento de registro de implicación/engagement en la actividad para la observación sistemática de personas mayores con deterioro cognitivo

Introduction

As the level of cognitive impairment in people with dementia increases, it seems that the interventions aimed at this group do not obtain the expected results. Thus, it is clear that there is a need to develop specific assessment tools. One of the important aspects in people with dementia is the engagement, involvement in task and activities. Engagement is considered a quality of life and quality of care indicator. The aim of the study is to develop an Engagement recording tool for mapping people with dementia, and to obtain reliability measures.

Method

The present paper aims to present the current development of engagement behaviours. The pilot study had a sample of 19 people distributed into two groups, which were observed in order to obtain inter-rater reliability measurements using the percentage of inter-rater agreement.

Results

An observational mapping instrument was developed that achieved a high inter-rater reliability.

Conclusion

The Engagement recording tool makes it possible to gather promising results on the effects of the interventions for people with severe dementia. On the other hand, these results point to the possibilities of more specific tools to assess the different interventions which aim is to improve quality of life and quality of care in people with dementia.     

Delirium en centros residenciales para personas mayores. Estudio de la prevalencia y los factores asociados

Objectives

To study the prevalence of delirium in the residential environment and to analyse the associated clinical, functional and mental factors.

Material and methods

A cross-sectional epidemic study was conducted on a population of elderly persons institutionalised in 2011 in 6 nursing homes in Asturias. Socio-demographic, clinical, functional (Barthel Index [BI]) and mental (Mini-Mental State Examination [MMSE]) variables were collected. Delirium was defined by the Confusion Assessment Method.

Results

A total of 505 elderly were included in the study (age 83.30 ± 7.33 years, with 67.70% women), and scores on the MMSE of 17.19 ± 10.35 and a BI score of 55.11 ± 35.82. The prevalence of delirium was 11.70%. On examining the risk of delirium among the studied variables, there was statistical significance when considering: BI, MMSE, dementia, pressure ulcers, or urinary catheter, and the prescribing of clomethiazole, ACTH-I or trazodone. In the analysis of the variables in the logistic regression with BI, diagnosis of dementia, the prescribing of clomethiazole or trazodone, in the equation, there was a statistical significance associated with delirium.

Conclusions

The prevalence of delirium in a residential environment in our study population was 11.7%. The results show that BI, diagnosis of dementia, and prescribing of clomethiazole or trazodone were associated with risk of delirium in institutionalised patients.     

Diseño y validación de las escalas de evaluación del impacto psicológico de sucesos vitales pasados: el papel del pensamiento rumiativo y el crecimiento personal

Introduction

Older people's emotional distress is often related to rumination processes focused on past vital events occurred during their lives. The specific coping strategies displayed to face those events may contribute to explain older adults’ current well-being: they can perceive that they have obtained personal growth after those events and/or they can show a tendency to have intrusive thoughts about those events. This paper describes the development and analysis of the psychometric properties of the Scales for the Assessment of the Psychological Impact of Past Life Events (SAPIPLE): the past life events-occurrence scale (LE-O), ruminative thought scale (LE-R) and personal growth scale (LE-PG).

Material and methods

Participants were 393 community dwelling elderly (mean age=71.5 years old; SD=6.9). In addition to the SAPIPLE scales, depressive symptomatology, anxiety, psychological well-being, life satisfaction, physical function and vitality have been assessed.

Results

The inter-rater agreement's analysis suggests the presence of two factors in the LE-O: positive and negative vital events. Confirmatory Factor Analysis (CFA) supported this two-dimensional structure for both the LE-R and the LE-PG. Good internal consistency indexes have been obtained for each scale and subscale, as well as good criterion and concurrent validity indexes.

Conclusions

Both ruminative thoughts about past life events and personal growth following those events are related to older adults’ current well-being. The SAPIPLE presents good psychometric properties that justify its use for elderly people.     

La evaluación de la calidad de vida en personas con demencia

Quality of life (QoL) is one of the most important outcome variables in the study of the efficacy of interventions with people with dementia. However, its assessment is difficult 1) because it is a complex construct for which there is no unified theoretical or conceptual approach, and 2) because of the inherent difficulties in the cognitive impairments of the people under study. In this work different methods and instruments to this end are reviewed, and related findings are discussed. It is important to take into account the subjective view of the assessed person, as assessments done by proxies tend to underestimate QoL. In spite of the need for further development in this field, it is concluded that the instrument of choice is the QOL-AD, as it is change-sensitive, it correlates with health measurements, it is translated into several languages and it can be administered to people with low MMSE scores.     

Prevención primaria del ictus en el anciano: evidencias actuales en el tratamiento de la hipertensión arterial

After age, arterial hypertension (AHT) is the most significant risk factor associated with stroke, and accounts for more than 25% of all strokes. The prevalence of AHT in the elderly in Spain is approximately 70%, which means that there are more than 5 million people over 65 years-old with hypertension in our country. There are currently numerous trials and meta-analyses that demonstrate that antihypertensive treatment clearly reduces the risk of stroke in elderly, and very elderly (≥80 years) subjects. However there are many areas of uncertainty such as, for example, when to start antihypertensive treatment, to what level should the blood pressure be lowered, or what is the best antihypertensive in the prevention of stroke in this population. In this article we present a review of the current evidence in the prevention of stroke in the elderly patient by means of treatment of the AHT.     

Déficit de vitamina D en una cohorte de mayores de 65 años: prevalencia y asociación con factores sociodemográficos y de salud

Introduction

Vitamin D deficiency is common in the elderly, especially among institutionalized and/or hip fracture patients. However, there are few population studies on the prevalence of this deficiency in the general population over 64 years in our environment. The aim of this study was to determine the prevalence of vitamin D deficiency in an urban population cohort of over 64 years, and analyze its relationship with sociodemographic, climatic, and health factors.

Material and methods

Cross-sectional study from «Peñagrande cohort», a population-based cohort consisting of people over 64 years. We determined 25-hydroxyvitamin D levels, and recorded sociodemographic data (age, sex, marital status, education, socioeconomic status), season of measurement and health variables (comorbidity, obesity, malnutrition, renal failure, cognitive impairment, vitamin D supplements, and disability).

Results

A total of 468 individuals with a mean age of 76.0 years (SD: 7.7) were included, of which 53.4% were women. The mean value of vitamin D was 20.3 ± 11.7 ng/mL. The large majority (86.3%, 95% CI: 83.0-89.5) had a vitamin insufficiency (≤ 30 ng/ml), and 35.2% (95% CI: 30.8-39.7) showed severe vitamin deficiency (≤ 15 ng/ml). Vitamin insufficiency increases linearly with age (OR 1.06; 95% CI: 1.01-1.11), and was associated with low socioeconomic status (OR 3.29; 95% CI: 1.55-6.95). Severe vitamin D deficiency increases with age (OR 1.06; 95% CI: 1.02-1.09), female gender (OR 1.80; 95% CI: 1.18-2.75) and with cognitive impairment (OR 1.71; 95% CI: 1.04-2.83).

Conclusion

The prevalence of vitamin D deficiency in people over 65 years of age in our community is high. It would be advisable to determine the vitamin D values in the high risk elderly in order to introduce measures of pharmacological supplementation in those with inadequate levels.     

Actualización en el manejo de la degeneración macular asociada a la edad

Age-related macular degeneration is the leading cause of legal blindness in people over 50 in developed countries. It is a multifactorial disease resulting from the interaction of genetic and environmental factors, and the age is the only worldwide admitted risk factor. The socioeconomic impact of the disease reaches enormous proportions, if we take into account the high cost of the available antiangiogenic therapy, the strict schedule of medical visits that it requires, and the impairment that it gives rise to. The response to treatment and the visual outcomes improve with early management of the retinal lesions, thus the early diagnosis of the disease in its initial phases, based on self-control with an Amsler grid and with regular ophthalmologic assessments, is essential.     

La participación de personas con demencia en las reuniones del plan de atención individualizada: impacto en el bienestar y la calidad del cuidado

Introduction

An individualised intervention plan (IIP) offers a new paradigm in the care of the elderly with dementia, with the aim of increasing their quality of life through personalisation, respect for their freedom, and their participation in the decisions that affect their lives.

Objective

To evaluate the impact of the residential home patient with dementia and their quality of care when they take part in the interdisciplinary meeting in which their care plan is decided.

Material and methods

A total of 52 elderly patients with dementia took part in the study. They were distributed into two groups, one experimental (37 residents) and another control (15 residents). The Dementia Care Mapping (DCM) tool was used to assess the well-being and quality of care of the residents. This tool was used twice, before and after the intervention.

Results

The well-being of the resident, evaluated using the DCM, was similar before and after the intervention in the experimental group. No differences were observed either on comparing the control and experimental groups. However, some indicators of carer behaviour were different before and after the intervention, and when the control and experimental group were compared.

Conclusion

The inclusion of elderly persons with dementia in their IIP meeting had a positive effect in the interaction of the staff with the residents, but not on the well-being of the resident.     

Síntomas depresivos en adultos mayores participantes de una universidad abierta a la tercera edad

Introduction

Although depressive disorders prevalence among older adults usually is less than in the younger population, the presence of significant symptoms of depression is common in elderly people. Studies show that taking part in social, educational and pleasure activities is associated with a reduction in depressive symptoms in this population. The purpose of this study was to examine the prevalence of depressive symptoms above the elderly participants of a Third Age Open University, taking the time taking part as a reference.

Material and methods

A cross-sectional design was implemented, with a participation of 95.2% (n = 140) of the total enrolled in the first trimester of 2009 in the activities of the Third Age Open University of the Schools of Arts, Sciences and Humanities of the University of São Paulo. They all answered a socio-demographic questionnaire and the Geriatric Depression Scale (GDS-15).

Results

The prevalence of depressive symptoms found was 3.57%. The statistical analysis showed a relationship between participation formore than one semester in the Third Age Open University and a lower index of depressive symptoms (p < .05).

Conclusions

Participating for longer than one academic semester is associated with less depressive symptoms, possibly being a protector factor against depression.     

Factores asociados a la polifarmacia en población anciana no institucionalizada. Análisis de la submuestra de la Encuesta Nacional de Salud 2006 para personas mayores de Castilla y León

Background

The increase in chronic and degenerative diseases in the elderly leads to increased and multiple drug usage, which in turn leads to problems associated with adverse reactions and drug interactions.

Material and methods

We analysed the subsample of the National Health Survey 2006, for adults over 65 living in Castile-León (n = 458). Using a logistic regression model and correlation analysis the variables having more influence on polypharmacy were evaluated.

Results

A total of 86% of those interviewed claimed to be taking drugs and 93.9% had a chronic illness. The most common health problems included arthrosis, arthritis or rheumatism (53.5%) and hypertension (48.3%), and most frequently used drugs were hypotensives (45%), pain medications (37.1%) and those for rheumatism (21.4%). Both the mean number of illnesses suffered and the drugs consumed are significantly higher in those who claimed to have, “or or fair health, used the health services, had impaired eyesight and hearing, dependent for personal care and domestic tasks, and mobility (P < .05). The variables associated with polypharmacy are three or more chronic diseases (OR = 18.3), regular-poor self perceived health (OR = 3.4) and females (OR = 1.9).

Conclusions

Given the magnitude of the problem it would be appropriate to include a review of the medications in health examinations of the elderly, particularly in women older than 75 years, with regular or self-perceived poor health and who have 3 or more diseases.
