Higher church attendance predicts lower fear of falling in older Mexican-Americans.

Several studies have shown that involvement in religious activity appears to benefit health. To estimate the association between church attendance and fear of falling, we used a sample of 1341 non-institutionalized Mexican-Americans aged 70 and over from the third wave (1998-1999) of the Hispanic Established Population for the Epidemiological Study of the Elderly, followed until 2000-2001. Baseline potential predictors of fear of falling were church attendance, socio-demographics, history of falls, summary measure of lower body performance (tandem balance, eight-foot walk, and repeated chair stands), functional status, depressive symptoms, cognitive status, and medical conditions. Fear of falling at the two-year follow-up was measured as no fear, somewhat afraid, fairly afraid, and very afraid. Chi-square statistic and multiple logistic regression analysis were used to estimate associations between the outcome and the potential predictors. Multiple logistic regression analysis showed that frequent church attendance was an independent predictor of lower fear of falling (odds ratio = 0.73, 95% confidence interval 0.58-0.92, P = 0.008) two years later. Other independent predictors of fear of falling were female gender, poorer objective lower body performance, history of falls, arthritis, hypertension, and urinary incontinence. Frequent church attendance is associated with decreased fear of falling in older Mexican-Americans.

Common infections in older adults.

Infectious diseases account for one third of all deaths in people 65 years and older. Early detection is more difficult in the elderly because the typical signs and symptoms, such as fever and leukocytosis, are frequently absent. A change in mental status or decline in function may be the only presenting problem in an older patient with an infection. An estimated 90 percent of deaths resulting from pneumonia occur in people 65 years and older. Mortality resulting from influenza also occurs primarily in the elderly. Urinary tract infections are the most common cause of bacteremia in older adults. Asymptomatic bacteriuria occurs frequently in the elderly; however, antibiotic treatment does not appear to be efficacious. The recent rise of antibiotic-resistant bacteria (e.g., methicillin-resistant Staphylococcus aureus and vancomycin-resistant enterococcus) is a particular problem in the elderly because they are exposed to infections at higher rates in hospital and institutional settings. Treatment of colonization and active infection is problematic; strict adherence to hygiene practices is necessary to prevent the spread of resistant organisms.

Ethnic differences in mini-mental state examination (MMSE) scores: where you live makes a difference.

OBJECTIVES: To examine differences in correlates of the Mini-Mental State Examination (MMSE) in a population-based sample of older Mexican Americans and European Americans and to provide empirical validation of the MMSE as an indicator of cognitive impairment in survey research in older Mexican Americans by comparing MMSE classification against performance on timed tasks with varying levels of cognitive demand. DESIGN: A population-based cross-sectional study. SETTING: Trained bilingual staff administered the MMSE as part of the San Antonio Longitudinal Study of Aging (SALSA) home-based assessment battery. PARTICIPANTS: 827 community-dwelling Mexican Americans and European Americans, 65 and older, residing in three socioeconomically and culturally distinct neighborhoods (barrio, transitional, suburban). MEASUREMENTS: The MMSE was compared against a variety of demographic, biomedical, and sociocultural variables ascertained by self-report and against performance-based measures of functional tasks representing varying levels of cognitive demand (Structured Assessment of Independent Living Skills (SAILS) subscales for food manipulation and money management). RESULTS: Mexican Americans were 2.2 times more likely than European Americans to have MMSE scores <24. Multiple logistic regression analysis revealed that neighborhood was an independent predictor of low MMSE scores in Mexican Americans, with the relationship between ethnic group and MMSE explained by neighborhood. After adjusting for neighborhood type, no differences were noted between Mexican Americans and European Americans. Independent of other factors examined, low education was associated with low MMSE scores in both Mexican Americans and European Americans. Mexican Americans with MMSE scores <24 took significantly longer to complete four out of five performance-based food manipulation tasks and all three money management tasks. CONCLUSIONS: Neighborhood type was a predictor of cognitive impairment. Education affected MMSE scores similarly in both ethnic groups. MMSE scores <24, indicative of cognitive impairment, were uniformly associated with functional impairment in both the Mexican Americans and European Americans. Among older Mexican Americans, MMSE-classified cognitive impairment was significantly associated with poorer performance on timed tasks with varying levels of cognitive demand independent of other correlates. A similar pattern of association was observed in European Americans. Thus, the MMSE appears to be a valid indicator of cognitive impairment in survey research in both older Mexican Americans and European Americans.

New-onset incontinence and markers of frailty: data from the Hispanic Established Populations for Epidemiologic Studies of the Elderly.

BACKGROUND: Urinary incontinence in older adults has many distinct etiologies and is associated with lower self-reported health. However, it is unclear whether the new onset of urinary incontinence marks newly emergent frailty. METHODS: Using a longitudinal population-based survey of older Mexican Americans (N = 2660) across five south-western states, this study compared the strength of association between markers of physical frailty such as activities of daily living (ADLs), instrumental activities of daily living (IADLs), and performance (timed walk, timed chair rise, and tandem balance) with baseline incontinence (prevalent disease) and new-onset incontinence (incident disease). RESULTS: We found that 14.1% of the participants (n = 329) were incontinent at baseline (prevalent cases) and 11.6% (n = 208) were newly incontinent 2 years later (incident cases). Controlling for other covariates, prevalent incontinence was only associated with a 60% increased risk of having difficulty walking 8 ft. Incident incontinence was associated with a twofold increased risk of impairment in ADLs and IADLs, and poor performance on all three physical measures. CONCLUSIONS: Incident incontinence is associated with an increased risk of more global functional impairment. Thus, incident disease may be an important early marker for signaling the onset of frailty among persons who become incontinent after the age of 65 years.

The use of herbal medicine by older Mexican Americans.

BACKGROUND: Little is known about use of herbal medicines by older Mexican Americans. The objective of this study was to determine the characteristics among older Mexican Americans that correlate with use of herbal medicines. METHODS: We administered a cross-sectional regional sample survey, the 1993-1994 Hispanic Established Populations for the Epidemiologic Study of the Elderly of Mexican Americans, by in-home interviews of noninstitutionalized older Mexican Americans age 65 and over living in Texas, New Mexico, Colorado, Arizona, and California. RESULTS: The use of herbal medicine in the 2 weeks prior to the interview was reported by 9.8% of the sample. Chamomile and mint were the two most commonly used herbs. Users of herbal medicines were more likely to be women, born in Mexico, over age 75, living alone, and experiencing some financial strain. Having arthritis, urinary incontinence, asthma, and hip fracture were also associated with an elevated use of herbal medicines, whereas heart attacks were not. We found that herbal medicine use was substantially higher among individuals reporting any disability in activities of daily living, poor self-reported health, and depressive symptoms. Herbal medicine use was associated with the use of over-the-counter medications but not with prescription medications. Herbal medicine use was particularly high among respondents who had over 24 physician visits during the year prior to interview. CONCLUSIONS: Herbal medication use is common among older Mexican Americans, particularly among those with chronic medical conditions, those who experience financial strain, and those who are very frequent users of formal health care services.

Prevalence, incidence, and risk factors associated with hip fractures in community-dwelling older Mexican Americans: results of the Hispanic EPESE study. Establish Population for the Epidemiologic Study for the Elderly.

OBJECTIVES: To determine the rates and risk factors associated with hip fractures in the community-dwelling older Mexican-American population. DESIGN: A prospective survey of a regional probability sample of older Mexican Americans aged 65 and over. SETTING: The 1993-1996 Hispanic Established Population for the Epidemiologic Study of the Elderly (H-EPESE), a probability sample of noninstitutionalized Mexican Americans, aged 65 and over, living in the Southwestern states of Texas, New Mexico, Colorado, Arizona, and California. PARTICIPANTS: In 1993-1994 and in 1995-1996, 2895 persons, aged 65 and over, considered Mexican American, were selected at baseline as a weighted probability sample. Sample weights were used to extrapolate to the estimated 498,176 older Mexican Americans residing in the Southwest US. MEASUREMENTS: Self-reported hip fracture and functional measures by in home interviews. RESULTS: Hip fracture prevalence was 4.0% at baseline. The overall incidence of hip fractures for women was 9.1 fractures/1000 person-years. The incidence rate for men was 4.8 fractures/1000 person-years. Extrapolation from these data to the entire older Mexican American population indicated that approximately 5162 new fractures occurred in the population during the 2 year study period. In women, hip fractures were associated independently with advanced age, not being married/living alone, having had a stroke, limitations with activities of daily living and instrumental activities of daily living. In men, only the latter limitations were associated independently with hip fracture. CONCLUSIONS: This study indicates that older Mexican American people may have hip fracture incidence rates that place them at highest risk among the Hispanic subgroups. In light of a sparse literature on this population, the fracture estimates derived from this work contributes to our understanding of the true fracture estimates in this population. Based on the extrapolated population rates, hip fracture in this population is a significant public health problem. Adequate preventive measures need to be implemented in this growing US population.

Health screening in older women.

Health screening is an important aspect of health promotion and disease prevention in women over 65 years of age. Screening efforts should address conditions that cause significant morbidity and mortality in this age group. In addition to screening for cardiovascular disease, cerebrovascular disease and cancer, primary care physicians should identify risk factors unique to an aging population. These factors include hearing and vision loss, dysmobility or functional impairment, osteoporosis, cognitive and affective disorders, urinary incontinence and domestic violence. Although screening for many conditions cannot be proved to merit an "A" recommendation (indicating conclusive proof of benefit), special attention to these factors can decrease morbidity and improve quality of life in aging women.

The influence of noncognitive factors on the Mini-Mental State Examination in older Mexican-Americans: findings from the Hispanic EPESE. Established Population for the Epidemiologic Study of the Elderly.

Mini-Mental State Examination data from the Hispanic Established Population for the Epidemiologic Study of the Elderly baseline survey, a population-based study of community-dwelling Mexican Americans aged 65 and older, were used to examine the relationship between cognitive impairment, sociodemographics, and health-related characteristics. The rate of cognitive impairment found in this group of older Mexican Americans, using the conventional cut point of 23/24 on the MMSE, was 36.7%. Using a more conservative cut point of 17/18 indicated an overall rate of severe cognitive impairment of 6.7%. Rates of impairment varied significantly with age, education, literacy, marital status, language of interview, and immigrant status and were associated with high and moderate levels of depressive symptoms, and history of stroke. Importantly, although education was strongly related to poor cognitive performance, it was not a significant predictor of severe cognitive impairment. Multivariate analyses further indicated that as a screen for cognitive impairment in older Mexican Americans, the MMSE is strongly influenced by these noncognitive factors. Scores may reflect test bias, secondary to cultural differences or the level of education in this population.

Changes in blood pressure and risk factors for cardiovascular disease among older Mexican-Americans from 1982-1984 to 1993-1994.

OBJECTIVE: To determine the 10-year changes in blood pressure and cardiovascular risk factors among older Mexican-Americans. DESIGN: Comparative analyses of the Hispanic Health and Nutrition Examination Survey (HHANES) and the Hispanic EPESE (Established Populations for Epidemiologic Studies of the Elderly). Both of these were population-based studies using a multistage stratified probability sampling design of noninstitutionalized persons. SETTING: Five US states in the southwest: Arizona, California, Colorado, New Mexico, and Texas. PARTICIPANTS: A total of 216 Mexican-Americans aged 65 to 74 from the 1982-1984 HHANES and 3050 Mexican-Americans aged 65+ from the 1993-1994 Hispanic EPESE. MEASUREMENTS: Mean systolic and diastolic blood pressure; cigarette smoking; high levels of alcohol use; body mass index and obesity; self-reported heart attack, stroke, and diabetes; hypertension. RESULTS: Among 65- to 74-year-old Mexican-Americans, there was a decrease over time in the percent of those who smoked cigarettes from 27.60% to 13.96% and a decrease in mean systolic blood pressure level. The percent of subjects categorized as obese or severely obese increased significantly, as did the prevalence of diagnosed diabetes, increasing from 20.06% in 1982-1984 to 29.82% in 1993-1994. Mean diastolic blood pressure increased from 77.15 mm Hg in 1982-1984 to 81.21 mm Hg in 1993-1994. CONCLUSIONS: Our findings suggest major changes in cardiovascular risk factors between 1982-1984 and 1993-1994 among older Mexican-Americans.

Diagnostic approach to the confused elderly patient.

Confusion in the elderly patient is usually a symptom of delirium or dementia, but it may also occur in major depression and psychoses. Until another cause is identified, the confused patient should be assumed to have delirium, which is often reversible with treatment of the underlying disorder. Causes of delirium include metabolic disorders, infections and medications. Thyroid dysfunction, vitamin deficiencies and normal-pressure hydrocephalus are some potentially reversible causes of dementia. Major irreversible causes include Alzheimer's disease, central nervous system damage and human immunodeficiency virus infection. All but the rarest causes of confusion can usually be identified based on the complete history, medication review, physical examination, mental status evaluation and laboratory evaluation with longitudinal reevaluation.

Dementia in older minority populations. Issues of prevalence, diagnosis, and treatment.

Dementia continues to be a major disease that affects older Americans. It has been estimated that up to 25% of all community-dwelling elderly individuals in the United States suffer from signs or symptoms of dementia. Little, however, has been written on dementia as it relates to older minority populations. The purpose of this article is to discuss the prevalence of dementia in elderly minority populations, describe some of the unique issues related to the diagnosis and treatment of dementia in these populations, and make recommendations aimed toward improving the quality of life for elderly minority individuals with dementia.

Undertreatment of hypertension in older Mexican Americans.

OBJECTIVE: To identify the prevalence of hypertension and factors associated with nontreatment and poor control of hypertension in Mexican Americans aged 65 years and older. DESIGN: A population-based survey of older Mexican Americans conducted in 1993-1994. SETTING: Subjects residing in five Southwestern states: Texas, New Mexico, Colorado, Arizona, and California. PARTICIPANTS: An area probability sample of 3050 noninstitutionalized Mexican American men and women aged 65 and older took part in a 90-minute in-home interview, which included review of all medications taken and two sitting blood pressure measurements. OUTCOME MEASURES: Measured were previous diagnoses of hypertension, current medication for hypertension, and current blood pressure RESULTS: Sixty-one percent of older Mexican-Americans were hypertensive, and 51% of those with hypertension were taking antihypertensive medications. Only 25% of hypertensive subjects (18% of males and 30% of females) were in good blood pressure control (i.e., systolic blood pressure < 140 mm Hg and diastolic blood pressure < 90 mm Hg). In multivariate analyses, factors associated with increased likelihood of treatment included female gender (OR = 1.9), history of heart disease (OR = 2.4), possessing a regular source of health care (OR = 2.7), and having seen a physician two or more times in the previous year (OR = 3.8). These were also independent predictors of good blood pressure control. CONCLUSION: Nontreatment of hypertension is still a major public health concern in older Mexican Americans. We estimate that adequate blood pressure control in this population would prevent approximately 30,000 adverse cardiovascular events over 10 years, affecting approximately 6% of the entire Mexican American older population.

Correlates of prescription and over-the-counter medication usage among older Mexican Americans: the Hispanic EPESE study. Established Population for the Epidemiologic Study of the Elderly.

OBJECTIVES: To determine the prevalence rates of prescription and over-the-counter (OTC) medication usage among community-dwelling older Mexican Americans. DESIGN: Cross-sectional survey of a regional probability sample of older Mexican Americans. SETTING: The 1992-1997 Hispanic Established Population for the Epidemiologic Study of the Elderly (H-EPESE), a probability sample of noninstitutionalized Mexican Americans, age 65 and over, living in the five Southwestern states of Texas, New Mexico, Colorado, Arizona, and California. PARTICIPANTS: 2899 persons, age 65 and over, considered Mexican American, using appropriate weighting procedures to produce regional estimates. OUTCOME MEASURES: Use of prescription and OTC medication within the last 2 weeks before the survey confirmed by in-home review of medication containers. RESULTS: Medication users consumed a mean of 2.9 prescription and 1.3 OTC medications. Over half (58.9%, n = 1,798) of the participants used at least one prescribed medication, and 31.3% (n = 847) used at least one OTC medication within the 2 weeks before their participation in the study. Factors associated with both prescription and OTC medication usage were self-perceived health and number of co-morbid conditions. Factors associated only with prescription medication usage included female gender, alcohol usage, ADL dependency, and presence of additional insurance. Structural assimilation was associated only with OTC medication usage. CONCLUSIONS: These data show lower prevalence rates of prescription medication usage among Mexican American older men and lower rates of OTC medication usage in older Mexican Americans of both genders than previously reported in other ethnic groups. This may reflect differences in time and geographic location of the Hispanic EPESE relative to other EPESE studies, ethnic differences in access to care as reflected by insurance in addition to Medicare, ethnic differences in survival, especially among males, or ethnic differences in medication preferences.

A Spanish version of the geriatric depression scale in Mexican-American elders.

OBJECTIVE: The purpose of this study was to establish the sensitivity of a Spanish translation of the 15-item Geriatric Depression Scale (GDS-S) in a sample of 41 elderly Mexican-American psychiatric patients with a diagnosis of depressive disorders. METHOD: Utilizing the reverse translation technique and bilingual Mexican-American psychiatrists as evaluators, patients with DSM-III-R diagnoses of affective disorder who were sequential admissions to an inpatient psychiatric unit were enrolled in the study. The GDS-S was administered by trained interviewers within 2-4 weeks of admission to 28 patients with major depressive disorder (MDD) and 13 patients with other depressive disorders (ODD). No other screening instruments for depressive symptoms were used. RESULTS: Using the original cut-scores of GDS, the sensitivity was 39% in patients with MDD and 77% in patients with ODD. When a revised cut-score of 4 and above was identified as reflective of depressive symptoms, the sensitivity improved to 75% for patients with MDD and 85% for patients with ODD. Because there were no true negatives, specificity was not determined. CONCLUSIONS: The GDS-S may have limited value in screening community-resident Mexican-American elders for depressive symptoms unless they have significant medical problems which limit their function and are associated with a dysthymic disorder. Screening instruments for depression which include neurovegetative or somatic items may be a better choice in this population.

SES and ethnic differences in perceived caregiver availability among young-old Mexican Americans and non-Hispanic whites.

Differences in perceived caregiver availability were examined among a random sample of Mexican American (MA) and non-Hispanic white (NHW) young-old residents (58-74 years old) in three socioeconomically distinct neighborhoods in San Antonio, Texas. For MAs across all three socioeconomic status (SES) groups, being female, widowed, and having more chronic illnesses were associated with a lesser likelihood of perceived caregiver availability. SES and number of children were not associated with perceived caregiver availability. Among MAs and NHWs of middle- and upper-SES, being male, married, and of upper-SES were associated with a greater likelihood of perceived caregiver availability. The number of children modified the associations of both SES and ethnic group with perceived caregiver availability.

Mortality differences between elderly Mexican Americans and non-Hispanic whites in San Antonio, Texas.

OBJECTIVE: To identify differences in causes of death between elderly Mexican Americans (MA) and non-Hispanic whites (NHW). DESIGN: Retrospective death certificate review. SUBJECTS: Elderly Mexican Americans and non-Hispanic Whites age 65 and over who died in Bexar County, Texas during 1989. MEASURES: Data obtained from chart review included age, sex, race/ethnicity, and cause of death. Age-adjusted and cause-specific mortality rates, odds ratios (OR), and 95% confidence intervals (CI) were calculated. RESULTS: Mexican Americans were at greater risk of dying in nine of the thirty causes of death examined. The mortality rates of MA subjects were higher than those of NHW from death caused by diabetes (OR = 3.19, CI = 2.27-4.49), renal failure (OR = 2.06, CI = 1.44-2.94), congestive heart failure (OR = 1.50, CI = 1.44-2.94), and multiple systemic diseases (OR = 2.59, CI = 1.89-3.57). Among the male subjects, MA had a greater risk than NHW of dying from myocardial infarction (OR = 1.83, CI = 1.15-2.90), coronary disease (OR = 1.37, CI = 1.07-1.75) and septicemia/pyuria (OR = 2.12, CI = 1.09-4.10). Among female subjects, MA had a greater likelihood of dying from cirrhosis (OR = 3.03, CI = 1.00-9.29). For only one of the causes of death was the risk lower among MA than NHW: MA female subjects had a lesser chance of dying from the chronic obstructive pulmonary disease (COPD) than NHW females (OR = 0.36, CI = 0.18-0.72). CONCLUSION: Mexican American elders have a greater risk of dying from non-insulin dependent diabetes mellitus and renal failure than their NHW counterparts. Elderly MA men have a greater risk of dying from cardiovascular disease than their NHW counterparts. Mexican American women may have a greater risk of dying from cirrhosis, but a lower risk of dying from complications of COPD. Finally, death from ill defined causes, such as multiple systemic diseases, may be a major under-acknowledged cause of death among older MA.
