Validation of questionnaires to estimate adherence to the Mediterranean diet and life habits in older individuals in Southern Spain.

The aim of the present study was to determine the nutritional behaviour of an elderly urban population in Southern Spain, estimating their degree of adherence to the Mediterranean. DIET DESIGN: A population-based cross-sectional nutritional survey, recruiting a representative sample of elderly inhabitants. The study sample comprised 260 people. The mean age was 73.60 yrs for the men and 72.25 yrs for the women. Around 70% lived with their family. The questionnaires used were first validated by using the Bland-Altman plot and the Wilcoxon test for paired samples. The degree of adherence to the Mediterranean Diet was around 50%, similar to findings in other Mediterranean populations. We highlight the mean consumption of milk and milk products (300-317 g/day) and of fruit/vegetables (250 g/day), which are slightly below recommendations. Our study subjects were all autonomous in their movements and were physically independent: 80% reported that they performed some type of physical activity. In this study, both adherence to the Mediterranean Diet and physical activity were considered as components of a healthy life. In summary, a majority of this elderly population was slightly overweight, considered themselves to be in good health.

Prevalence of psychiatric and physical morbidity in an urban geriatric population

Background:With a rapidly increasing population of older aged people, epidemiological data regarding the prevalence of mental and physical illnesses are urgently required for proper health planning. However, there is a scarcity of such data from India.Aims:To study the frequency and pattern of psychiatric morbidity present and the association of physical illness with psychiatric morbidity in an elderly urban population.Settings and Design:Cross-sectional, epidemiological study.Materials and Methods:All the consenting elderly persons in a municipal ward division (n=202) were enrolled after surveying a total adult population of 7239 people. A door to door survey was undertaken where the participants were interviewed and physically examined. General Health Questionnaire-12, Mini Mental State Examination, CAGE Questionnaire and Geriatric Depression Scale were used in the interview apart from consulting the available documents. Other family members were also interviewed to verify the information.Statistical Analysis:Chi-square test with Yates correction.Results:Psychiatric illnesses were detected in 26.7% while physical illnesses were present in 69.8% of the population surveyed. Predominant psychiatric diagnoses were depressive disorders, dementia, generalized anxiety disorder, alcohol dependence and bipolar disorder. The most common physical illness was visual impairment, followed by cardiovascular disease, rheumatic illnesses, pulmonary illnesses, hearing impairment, genitourinary diseases and neurological disorders. Presence of dementia was associated with increased age, single/widowed/separated status, nuclear family, economic dependence, low education, cardiovascular disorders, rheumatic disorders and neurological disorders. Depression was associated with female sex, single/widowed/separated status, staying in nuclear families, economic dependence on others and co-morbid physical illnesses, specifically cardiovascular disorders and visual impairment.Conclusions:This study presented a higher rate of dementia and old age depression. The interesting association with several sociodemographic factors as well as physical illnesses may have important implications for health planning.

Morbidity and Physical Functioning in Old Age: Differences According to Living Area

To describe differences in morbidity and functional status according to living area. Community-based survey. A community-based prospective cohort, the Kungsholmen-Nordanstig Project. Adults aged 75 and older living in an urban area of central Stockholm (n=1,222) and in the rural community of Nordanstig in northern Sweden (n=919). Physicians clinically examined all participants using the same standardized protocols in both living areas; trained nurses directly assessed disability. Cardiovascular disease was the most common disorder in both living areas (39.9% in the urban area and 45.2% in the rural area). There were great area differences in the prevalence of stroke (7.4% and 14.0%), diabetes mellitus 6.3% and 16.1%), and Parkinson's disease (1.0% and 3.7%). It was more common to have two or more diseases than no diseases in the rural area than in the urban area (odds ratio=1.9, 95% confidence interval=1.4-2.4). Significant living area differences (urban vs rural) in population attributable risk (PAR) was found for disability due to stroke (5.6 vs 32.2), diabetes mellitus (1.2 vs 6.1), fractures (1.4 vs 10.7), and hearing impairment (8.7 vs 22.0). Differences were found in disability, morbidity, and disease patterns according to living area. The rural elderly population was more disabled and had more diseases than the urban elderly population, despite being slightly younger than the urban cohort. There were significant area differences in the PAR of how specific chronic conditions influenced the risk of disability.

The role of health and non-health-related factors in repeat emergency department visits in an elderly urban population

IntroductionPatients aged 65 years or older account for a growing proportion of emergency department (ED) repeat attendances. This study aimed to identify health and non-health factors associated with repeat ED...

The Utility of Ambulatory Electrocardiographic Monitoring for Detecting Silent Arrhythmias and Clarifying Symptom Mechanism in an Elderly Urban Population with Heart Failure and Hypertension: Clinical Implications

Background: Atrial and ventriclar tachyarrhythmias, as well as bradyarrhythmias, in the elderly with heart failure (HF) and/or hypertension (HTN) have been well documented. However, the frequency of these arrhythmias, whether silent or symptomatic, and their association with subsequent cardiac events has not been well defi ned in patients 65 years or older with HF and other cardiovascular risk factors. Objective: To assess the value of 2 weeks of remote, transtelephonic cardiac monitoring for detecting arrhythmias in an elderly, urban population living with HF. Methods: Fi" y-four patients with a history of systolic HF and/or HTN were consented and enrolled. All wore an auto triggered cardiac loop monitor for 2 weeks that captures EKG data and both silent and symptomatic arrhythmias were recorded. Results: Mean age was 73 ± 6 years with 59% of subjects were females, 74% Hispanic, 22% black, and 4% white/other. All patients had HF and 94% had HTN. From the cardiac monitoring, 72% demonstrated ectopic atrial and ventricular activity, and 1 paroxysmal episode of atrial fi brillation was documented. In addition, 3 subjects had signifi cant non-sustained ventricular tachycardia, and 4 individuals had severe bradycardia recorded on cardiac monitoring. These 7 individuals underwent placement of an implantable cardioverter defi brillator (ICD) or pacemaker based on the documented arrhythmias which may have otherwise gone undetected. Conclusions: A substantial proportion of patients exhibited cardiac arrhythmias. Future morbidity was prevented because of the detection of arrhythmias on monitoring that led to specifi c therapies such as pacemaker or ICD implantation which otherwise may not have been implemented.

Feasibility and reliability of the elderly version of the Camberwell Assessment of Needs (CANE): results from the São Paulo Ageing & Health Study

We set out to assess the feasibility, reliability and convergent validity of the Camberwell Assessment of Needs for the Elderly Scale in older residents of a Brazilian urban elderly population of low socioeconomic status. We identified 32 older users of community health services from a population-based catchment area survey. We administered the Brazilian version of the Camberwell Assessment of Needs for the Elderly Scale to the older person and to an informal caregiver, and tape-recorded the assessments. Interviewers made a rating. Tape-recordings were independently co-rated. Items contributing to older person and caregiver reports of needs and unmet needs had a high internal consistency. Inter-rater reliability was excellent for all needs, and fair to good for unmet needs. Older person and caregiver's reports, and interviewer ratings were highly mutually consistent. Convergent validity was supported by associations, as hypothesized, between needs and disability, and needs and dementia. The Brazilian version of the Camberwell Assessment of Needs for the Elderly Scale is a feasible, reliable and, to the extent assessed, valid assessment of unmet needs in a disadvantaged low and middle income countries setting. Its practical utility as a clinical tool remains to be assessed.

Prevalence of Dementia and Its Subtypes in an Elderly Urban Korean Population: Results from the Korean Longitudinal Study on Health and Aging (KLoSHA)

Background/Aims: We estimated the prevalence of dementia and its major subtypes in an elderly urban Korean population. Methods: A study population of 1,118 Korean elders was randomly sampled from the residents aged 65 years or older living in Seongnam, Korea. Standardized face-to-face interviews, and neurological and physical examinations were conducted on 714 respondents. Dementia was diagnosed according to the DSM-IV diagnostic criteria, and its subtypes were determined according to the criteria of the NINCDS-ADRDA, the NINDS-AIREN, and the consensus guideline proposed by McKeith et al. [Neurology 1996;47:1113–1124]. Results: The estimated age- and gender-standardized prevalences were 6.3% for dementia (95% CI = 4.5–8.1), 4.8% for Alzheimer’s disease (AD; 95% CI = 3.3–6.4), 1.0% for vascular dementia (VD; 95% CI = 0.3–1.8), and 0.4% for dementia with Lewy bodies (DLB; 95% CI = 0.0–0.9). The prevalence of AD consistently increased with age, whereas that of VD peaked at age 75–79 years and decreased thereafter. Of the dementia patients, 72.0% were in the very mild or mild stages of the disease. Conclusions: The prevalence of dementia in a typical urban area of Korea was estimated to be 6.3%, and AD was the most prevalent subtype. DLB was less prevalent than VD among these community-dwelling Korean elders.

Knowledge, awareness, behavior (KAB) and control of hypertension among urban elderly in Western China

Objective To explore knowledge, awareness, behaviors (KAB) and control of hypertension among urban elderly population (≥ 60 years) in Xi'ning and Chengdu cities. Methods A 2-stage sampling method recruited 4141 participants sampled from 20 communities. Data collection included blood pressure measurements, using a mercury sphygmomanometer, and information about KAB and other factors through face-to-face structured questionnaire. Results The overall prevalence of hypertension (SBP ≥ 140 and/or DBP ≥ 90, and/or current treatment for hypertension) reached to 48.5%; 75.3% of hypertensive participants were aware about their disease; 32.1% in all hypertensive patients had controlled BP (BP < 140/90) and 48.2% of those treated had controlled BP. A higher proportion of hypertensive participants showed adequate knowledge on complications in comparison to knowledge about HTN risk factors. Participants with controlled BP were more knowledgeable about threshold, risk factors, and complications as a result of hypertension, had increased awareness, and took medications and BP measurements on regular basis with more inclination to follow or initiate treatment. In the logistic regression model, men (odd ratio [OR]: 1.31), good knowledge of hypertension risk factors (OR: 1.19), awareness of being hypertensive (OR: 2 * 10 9), and regular medication (OR: 1.48) were associated with controlled BP. Conclusion The control rate of hypertension was much higher in our study compared to the 2002 nation wide study and other studies performed in some developing countries. Health care providers ought to strengthen their measures by delivering appropriate knowledge to elderly patients about hypertension risk factors, raising more awareness among people about their hypertension status, and encourage more compliance towards treatment.

Life course, gender and ethnic inequalities in functional disability in a Brazilian urban elderly population

To examine life course social, gender and ethnic inequalities in ADL disability in a Brazilian urban elderly population. We used the São Paulo-SABE study (health, well-being and aging in Latin America and the Caribbean) to assess the associations between ADL disability and gender, ethnicity and life course social conditions (childhood socio-economic and health status, education, lifetime occupation, current perception of income), controlling for current physical and mental health (cognitive impairment and comorbidity). ADL disability was defined as the presence of one or more difficulties with six tasks: bathing, toileting, dressing, walking across the room, eating, and getting out of bed. Results suggest that social inequalities during the life course (hunger and poverty in early life; illiteracy, a low skilled occupation, having been a housewife; insufficient income) tend to result in disability in later life. The prevalence of ADL disability was higher among women (22.4%) than among men (14.8%). Mestizo/ Native elders reported higher prevalence of disability compared with Whites and Blacks/Mulattos. Ethnic inequalities concerning ADL disability were explained by social and health conditions, but the gender gap persisted (OR women vs men= 2.16; 95% CI 1.32-3.55). Despite their higher rate of ADL disability in old age, women appear to be more resilient than men toward poor socio-economic conditions throughout the life course. Chronic conditions were more likely to result in ADL disability among men than women (OR= 1.83; 95% CI 1.41-2.38 in women; OR= 3.42; 95% CI 2.41-4.86 in men). Decreasing social inequalities during childhood and adulthood will reduce socio-economic inequalities in disability in old age, especially among men.

Apolipoprotein E ɛ4, Alzheimer's Disease, and Cognitive Performance in Elderly Mexican Mestizos

To determine the relationship between apolipoprotein E (APOE) epsilon4 and Alzheimer's disease (AD) in the Mexican Mestizo population, as well as its effects on the cognitive profile of AD and elderly Mestizos without dementia. Cross-sectional analysis of a cohort study. Evaluations were conducted at the geriatrics clinic of an academic medical hospital in Mexico City. Forty-nine elderly subjects with AD and 141 controls selected from a representative sample of Mexican Mestizos aged 65 to 96 who participated in the Prevalence Survey of Dementia in the Mexico City Elderly Population cohort. All subjects underwent APOE genotypification and a comprehensive clinical and neuropsychological evaluation. There were no significant differences in epsilon3 and epsilon4 frequencies between the subjects with and without AD and a tendency toward higher epsilon4 and lower epsilon3 allele frequencies in subjects aged 75 and older. No association was found between APOE epsilon4 and the presence of AD. The age-, sex-, and education-adjusted risk for AD associated with at least one epsilon4 allele was 1.01 (95% confidence interval=0.45-2.23). Performance on a long-term visual memory test was significantly worse in APOE epsilon4 carriers than in APOE epsilon3 carriers only in the group with AD. APOE epsilon4 did not increase the risk for AD in this Mexican Mestizo elderly urban population sample, although the presence of this allele seems to modify its clinical expression.

Is the dementia rate increasing in Beijing? Prevalence and incidence of dementia 10 years later in an urban elderly population

To examine the time trend of dementia morbidity over the past decade in Beijing, China. In 1997, 1593 community-dwelling elderly aged 60+ years were examined and followed-up over 2-years to identify incident dementia. A similar cohort study of dementia conducted in the same district 10 years prior was used as historical comparison to examine the time trend of dementia incidence. Forty prevalent dementia cases were identified at the initial examination for a prevalence of 2.51% (95% CI: 1.74-3.28) and 25 incident cases were identified at the follow-up visit for an incidence of 0.90% (0.55-1.25) among residents aged 60+ years. Alzheimer's dementia (AD) was the most common type of dementia in both prevalent and incident cases. The prevalence and incidence rates of dementia in Beijing were slightly higher than those 10 years ago, which was partly because of population aging. AD became the most common subtype of dementia.

Prevalence and Risk Factors Associated With Obesity in the Elderly in Barbados

This article's objective is to examine the epidemiology of obesity in the urban elderly population of Barbados. A random sample of adults >/= 60 years underwent comprehensive interviews and measurement of their weight, height, and waist circumference (WC). Outcomes of interest were obesity (body mass index [BMI] > 30 kg/m2), high-risk WC (men >/= 102 cm; women >/= 88 cm), and high risk of disease comorbidity (from BMI and WC criteria). Total, 1,508 persons participated (80% response). Women had higher rates of obesity (31% vs. 11.9%), high-risk WC (61.9% vs. 13.9%), and disease co-morbidity risk (51.1% vs. 17.5%) compared to men. Multivariate regression confirmed female gender as an independent predictor of outcomes (p < 0.001). Other predictors were less consistent: self-reported fair/poor health status and eating two (vs. three) meals daily were associated with obesity, whereas semiprofessional occupation and unmarried status predicted high-risk WC. Obesity is highly prevalent among elderly Barbadians. Public health interventions must target this group, particularly women.

Socio-economic health differences among the elderly population in Krakow, Poland

To assess whether socio-economic health differences persist into old age in Poland and if there are SES-related differences in health by age group and gender. 528 randomly chosen, not institutionalized elderly people aged 65-85 living in Krakow were interviewed about their socio-economic status (occupation, education, income, house ownership), health status (self-rated health) and quality of life (Cantril's ladder). People with higher level of education and higher occupational status reported significantly better health and better quality of life compared to people who were not as well off. Income level and house ownership had a significant influence on the quality of life of elderly people. In addition, some findings indicate differences in the patterning of health inequalities across particular age and gender groups. There are socio-economic differences in health and quality of life among the urban elderly population in Poland which are unfavourable for lower social strata.

Factors associated with suicidal ideation in an elderly urban Japanese population: A community‐based, cross‐sectional study

The objective of the present study was to evaluate the association between suicidal ideation and potentially related factors in an elderly urban Japanese population. This was a community-based, cross-sectional study. Urban community residents aged 70 years or more were interviewed regarding suicidal ideation and sociodemographic and health-related variables. Subjects with depressive symptoms underwent further evaluation by psychiatrists using criteria of the Diagnostic and Statistical Manual of Mental Disorders, 4th edition. Associations were evaluated using univariate and multivariate logistic regression analyses. Of the 1145 eligible participants, 52 (4.5%) reported thoughts of suicide. Of 143 subjects with depressive symptoms (Geriatric Depression Scale, 14+), 22 (15.4%) reported suicidal ideation over a 2-week period. After controlling for depressive symptoms, lack of social support and impaired instrumental activities of daily living were significantly associated with thoughts of suicide. After controlling for the potentially associated factors detected in the univariate analysis, depressive symptoms were strongly associated with thoughts of suicide. In the elderly with depressive symptoms, mental disorders, including depressive and alcohol-related disorders, were significantly associated with suicidal ideation over a 2-week period. In the urban community setting, screening for lack of social support, impaired instrumental activities of daily living, and depressive symptoms, followed by diagnostic evaluation for mental disorders, particularly for depressive syndromes and alcohol-related disorders, may provide a practical and effective means of identifying elders at high risk of suicide.

Prevalence of dizziness and vertigo in an urban elderly population

The prevalence of balance symptoms (vertigo, dizziness, and dysequilibrium) was investigated in an epidemiological study of elderly people, the longitudinal and cross-sectional gerontological and geriatric population study from Göteborg, Sweden (H70). Three different age cohorts were studied, one at age 70, one at age 75 and one at ages 79, 82, 85, 88 and 90 years. Altogether 2011 participants answered the questionnaire at 3197 occasions. The overall prevalence of balance problems at age 70 was 36% (women) and 29% (men). Balance symptoms were more common among women than men, and increased with increasing age. At ages 88-90 years the corresponding values were 51-45%. The most common symptom was poor balance/general unsteadiness (11-41%). Rotatory symptoms occurred in 2-17%. Other types of symptoms were less common. Precipitating factors were rising from supine to sitting position in 17-40%. Balance symptoms in a side position were uncommon, but occurred more often when tilting the head backwards (up to 14%). Signs that possibly could indicate neurological involvement were uncommon. Falls in conjuncture to dizziness, vertigo and similar symptoms occurred in 7-15%, in about equal proportions indoors as outdoors.

Health-related quality of life among urban, rural, and island community elderly in Taiwan.

There are published norms of the 36-item short form of the Medical Outcomes Study Questionnaire (SF-36) for many countries, but few such studies have been conducted in Taiwan. The purpose of this study was to provide the norms for the SF-36 health status measure in urban, rural, and remote island community elderly populations, and to explore the relation between demographic or characteristic factors and the SF-36. A structured questionnaire was used for door-to-door data collection in this survey of an urban, a rural, and a remote population (Shihpai, Yuli, and Kinmen, respectively, in Taiwan). Interviewers also collected information on subjects' demographics, medical history, use of health services, and health-related quality of life using the SF-36. A total of 6503 subjects who were at least 65 years of age were invited, and 4424 (73.1%) participated in the survey. The urban norms were significantly higher than the rural norms in seven scales of the SF-36 and significantly higher than the remote island norms in 4 scales, including physical functioning (84.6 vs 77.1), role limitations due to physical problems (77.8 vs 70.2), general health perceptions (70.5 vs 65.5), and role limitations due to emotional problems (90.6 vs 85.2). Remote island norms were significantly higher than urban and rural norms in vitality and mental health scales. In the multivariate analyses, women had significantly poorer scores in all scales of the SF-36 than men (p < 0.05), except for social functioning. Higher education was significantly associated with increased scores in all scales, except for vitality/energy and mental health scales. Scores of all scales were significantly reduced according to the number of chronic diseases a subject had. The need for domestic services and utilization of inpatient and outpatient health services were associated with lower scales (p < 0.05). There were significant differences between urban, rural, and remote island elderly populations in most scales of the SF-36. The urban elderly population had the greatest health-related quality of life on most scales, particularly on the physical health scales. The remote island elderly population had the highest scores on the vitality and mental health scales, whereas the rural elderly population had the poorest health-related quality of life, particularly rural women.

The prevalence of symptomatic knee and distal interphalangeal joint osteoarthritis in the urban population of Antalya, Turkey

The aim of this cross-sectional study was to estimate the prevalence and risk factors of symptomatic knee and distal interphalangeal (DIP) joint osteoarthritis (OA) in the elderly (> or =50 years of age) urban population of Antalya, Turkey. According to the 1997 national census, Antalya's population was 508,840. By random cluster sampling, 655 individuals aged 50 years or more were interviewed face-to-face and subjected to structured interviews regarding knee pain, worsening pain on exertion, and the gelling phenomenon. They were also asked about performing namaz (a fundamental act of worship in Islam performed five times a day), smoking, type of residence, type of toilet, work style, and duration of walking per day. They were also questioned about swelling in DIP joints. In the case of suspicion of knee OA, the individuals were invited to the hospital for further evaluation by physical examination and direct roentgenogram. The diagnosis of knee OA was based on clinical or clinical and radiographic findings. The prevalence of symptomatic knee OA was determined as 14.8% in the population aged 50 years or over. Advanced age, female sex, namaz, and type of residence were found to be associated with knee OA. The rate of symptomatic knee OA was significantly lower in smokers and those walking more than 2 h per day. Female sex was also strongly associated with OA DIP joints. OA of DIP joints was found significantly associated with symptomatic knee OA. The latter is a major health problem in the elderly population, especially in about one fourth of women aged 50 years or over. These data suggest that advanced age, female sex, and type of residence are risk factors.

Circumstances of falls causing hip fractures in the elderly. 1998.

A prospective analysis was performed on 832 patients to determine the circumstances surrounding falls leading to hip fracture within a homogenous, elderly urban population. Special emphasis was placed on the season of year, time of day, location of fall, and other circumstances in which the fracture occurred. All patients were community dwelling, cognitively intact, previously ambulatory elderly who sustained a femoral neck or intertrochanteric fracture. Most fractures occurred at home, particularly in patients who were older, less healthy, and poorer ambulators. More than 75% of fractures resulted from a fall while the patient was standing or walking. Most falls occurred during daylight hours with a peak seen in the afternoon. No seasonal variation in the incidence of hip fractures was observed.

Cardiovascular risk factors in the elderly: the Tehran Lipid and Glucose Study.

Coronary artery disease is becoming more prevalent in developing countries, particularly in urban areas. Because the proportion of elderly individuals in the population is on the rise, this study was conducted to determine the prevalence of cardiovascular risk factors among the Tehran urban elderly population. Among 15,005 urban individuals of 3 years old and over who had been chosen in a cross-sectional phase of a longitudinal study in Tehran, there were 1,799 people aged 60 years and over. The prevalence and distribution of high blood pressure, cigarette smoking, dyslipoproteinemia, diabetes mellitus and obesity were determined in this population. Dietary intake was assessed in a subsidiary of 54 people by means of two 24 h dietary recalls. The percentage of women with two or more cardiovascular disease risk factors was significantly greater than in men (74% compared with 53%, P < 0.001). One fourth of men and 55% of women had high serum cholesterol levels (>/=240 mg/dl). The prevalence of diabetes mellitus and impaired glucose tolerance was 24% and 21% in men and 29% and 20% in women, respectively. The prevalence of obesity (body mass index >/=30 kg/m(2)) was 15% for men and 36% for women. Fifty-five per cent of men and 94% of women had high waist-to-hip ratios (>0.95 in men and >0.8 in women). The mean percentage values of energy intake derived from carbohydrate, protein and fat were 60.5 +/- 8.0, 11.5 +/- 2.0 and 27.8 +/- 8.9, respectively. The prevalence of cardiovascular risk factors among the Tehran urban elderly population is high. Some efforts should be made to reverse the recent trend towards increasing age-related mortality and morbidity rates of coronary heart disease.
