Postmenopausal hormone replacement therapy use by older Mexican-American women.

OBJECTIVES: To determine the prevalence of current hormone replacement therapy (HRT) use and describe its correlates among community-dwelling, Mexican-American women aged 67 and older. DESIGN: A population-based survey of older Mexican-Americans conducted in 1995/1996. SETTING: Five Southwestern states: Texas, New Mexico, California, Arizona, and Colorado. PARTICIPANTS: An area probability sample of 1,424 noninstitutionalized Mexican-American women aged 67 and older (mean age = 75.1) completed the survey instrument via a 90-minute in-home interview, which included examination and recording of all medications taken. MEASUREMENTS: Current use of HRT. RESULTS: In this sample of older Mexican-American women, 4.7% were current users of HRT. Controlling for sociodemographic characteristics (age, marital status, living arrangements, years of education, income, language of interview), current HRT use is significantly related to years of education (per each year) (odds ratio (OR) = 1.13; 95% confidence interval (CI) = 1.05-1.20), having had a hysterectomy (OR = 4.37; 95% CI 2.50-7.64), a diagnosis of osteoporosis (OR = 3.40, 95% CI = 1.58-7.33), age at menopause (per each year) (OR = 1.07; 95% CI = 1.03-1.12), ever having a mammogram (OR = 3.72; 95% CI = 1.66-8.37), ever having a Pap test/pelvic examination (OR = 2.11; 95% CI = 1.08-4.12), having spoken with a pharmacist within the past year regarding health conditions (OR = 1.96; 95% CI = 1.06-3.65), and having Medicare plus private insurance (OR = 2.13; 95% CI = 1.14-3.97). CONCLUSION: The prevalence of HRT use is lower than that reported in the older non-Hispanic white female population. In general, these findings indicate that access to and utilization of the traditional U.S. health care system are indicators of HRT use.

Chronic rheumatologic symptoms in a tri-ethnic sample of men and women aged 75 and older.

BACKGROUND: The high prevalence of musculoskeletal symptoms in elderly persons tends to obscure the recognition of specific medical conditions. The purpose of this study is to describe the prevalence of chronic rheumatologic symptoms and the associated measures of health status in an older population. METHODS: This is a cross-sectional study of 507 noninstitutionalized tri-ethnic men and women aged 75 and older living in Galveston County, Texas. A home interview collected data on demographics, chronic medical conditions, cognition, depression, and functional status. Site, severity, and duration of rheumatologic symptoms such as morning stiffness, body tenderness, and body aching in the past month were also collected. RESULTS: There was a high prevalence of nonspecific rheumatologic symptoms such as morning stiffness (32% in the shoulder girdle, 31% in the hip girdle), tenderness to touch (9%), and generalized body aching (11%) in the study population. Twenty-one percent of the subjects reported either bilateral shoulder or hip girdle stiffness or tenderness lasting more than 30 minutes almost every day or every day or generalized body aching most of the time during the past month. Age-, gender-, and ethnicity-adjusted multivariate analyses showed that more than three self-reported chronic medical conditions, poor or fair self-reported health, impairment in instrumental activities of daily living (IADL), and the presence of depressive or anxiety symptoms were associated with the presence of these chronic rheumatologic symptoms. CONCLUSION: Chronic rheumatologic symptoms are common in people aged 75 and older. Such symptoms are markers for underlying poor health and for anxiety and depression among older subjects.

Changes in the smoking behavior of elderly Mexican Americans in the Southwest from 1982-1984 to 1993-1994.

OBJECTIVES: The aim of this work was to examine changes in the smoking behavior of elderly Mexican Americans in the southwestern United States from the early 1980s to the early 1990s. METHODS: Data from the 1993-1994 Hispanic EPESE study (n = 2,809) on persons ages 65 to 74 and 75 to 84 residing in the five southwestern states were compared with data from the 1982-1984 Hispanic HANES study (n = 753, persons ages 55 to 74), which included a Mexican American sample from the same five southwestern states. RESULTS: Rates of current smoking in 1993-1994 for persons ages 65 to 74 were approximately half the rates for persons of the same age a decade earlier. Smoking rates for persons ages 75 to 84 in 1993-1994 were significantly lower than rates for persons ages 65 to 74 a decade earlier. Finally, rates for persons ages 65 to 74 in 1993-1994 were significantly lower than those for persons ages 55 to 64 in 1982-1984. CONCLUSIONS: Although some of the declines in smoking in recent years represent aging effects (including declines due to greater mortality among smokers), the much lower rates for same-age people (65 to 74) over the 10-year period are more significant in that they represent cohort differences. It appears that the broader public health message that is causing the general population to quit smoking is reaching the elderly Mexican American population of the Southwest.

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.

The prevalence and health burden of self-reported diabetes in older Mexican Americans: findings from the Hispanic established populations for epidemiologic studies of the elderly.

OBJECTIVES: The prevalence and health burden of self-reported adult-onset diabetes mellitus were examined in older Mexican Americans. METHODS: Data from the Hispanic Established Populations for Epidemiologic Studies of the Elderly were used to assess the prevalence of self-reported diabetes and its association with other chronic conditions, disability, sensory impairments, health behaviors, and health service use in 3050 community-dwelling Mexican Americans 65 years and older. RESULTS: The prevalence of self-reported diabetes in this sample was 22%, and there were high rates of obesity, diabetes-related complications, and diabetic medication use. Myocardial infarction, stroke, hypertension, angina, and cancer were significantly more common in diabetics than in nondiabetics, as were high levels of depressive symptoms, low perceived health status, disability, incontinence, vision impairment, and health service use. Many of the rate differences found in this sample of older Mexican Americans were higher than those reported among other groups of older adults. CONCLUSIONS: Our findings indicate that the prevalence and health burden of diabetes are greater in older Mexican Americans than in older non-Hispanic Whites and African Americans, particularly among elderly men.

The effect of medical conditions on the functional limitations of Mexican-American elderly.

We examined the relationship of self-reported functional status to common medical conditions using a probability sample of 3050 noninstitutionalized Mexican-American men and women aged 65 or older and residing in the Southwestern United States (Arizona, California, Colorado, New Mexico, and Texas). All subjects were interviewed in person (n = 2,873) or by proxy (n = 177) in their homes during late 1993 and early 1994. The questionnaire obtained information on self-reported functional status and prevalence of arthritis, cancer, diabetes, stroke, heart attack, and hip fracture. The prevalence of medical conditions ranged from 4.1% for hip fracture to 40.8% for arthritis. Prevalence of impairments in seven activities of daily living ranged from 5.4% for eating to 11.7% for bathing, while 25.1% could not walk up and down stairs, and 28.9% could not walk a half mile without help. In multiple logistic regression analyses, previous diagnoses of stroke and hip fracture were most predictive of functional limitations, though all conditions examined (arthritis, cancer, diabetes, stroke, heart attack, and hip fracture) were independently associated with increased odds of impairment in some activities of daily living. In general, the odds for functional impairment associated with specific medical conditions were higher than those previously published for non-Hispanic white populations. The fact that Mexican-American elderly who live in the community and who have medical conditions, especially stroke and hip fracture, are at high risk for functional impairment probably reflects the low rate of institutionalization in this population and has implications for the provision of community-based long-term care services for Mexican-American elderly.

Religious attendance and psychological well-being in Mexican Americans: a panel analysis of three-generations data.

This study examined the effects of religious attendance on three dimensions of psychological well-being using panel data from a three-generations study of Mexican Americans from Texas (N = 624). Well-being dimensions included life satisfaction (the 13-item LSIA), and respective seven- and four-item depressed and positive affect subscales of the CES-D. Two-wave path analyses revealed a cross-sectional association between religious attendance and life satisfaction in the two oldest generations, and a salutary longitudinal effect of religious attendance on subsequent depressed affect in the youngest generation. Findings for life satisfaction and depressed affect withstood controlling for health and five sociodemographic correlates of religious attendance and well-being.

Physicians' ratings of health in middle and old age: a cautionary note.

Physicians' global assessments traditionally have been considered to be relatively objective estimates of older people's health against which self-ratings of health and other self-reported measures are compared. Using data on middle-aged and older Mexican Americans from the Hispanic Health and Nutrition Examination Survey, it is suggested that the subjective component of physicians' assessments can create problems with validity, especially when a small number of physicians perform the assessments, as was the case in this study. It is recommended that researchers should not always assume that physicians' assessments represent an objective "gold standard" for validating self-reported measures of health.

Acculturation and hypertension in Mexican Americans.

In this analysis, we employ data from the Hispanic Health and Nutrition Examination Survey to examine the association between level of acculturation into the larger society and rates of hypertension in Mexican Americans. Analyses conducted separately by gender in three broad age groups (ages 20 to 39, 40 to 59, and 60 to 74 years) fail to indicate a linear effect of acculturation on hypertension after controlling for age, education, marital status, employment, smoking, alcohol consumption, and body mass index. A nonlinear hypothesis was subsequently examined and found partial support among middle-aged men. Other things equal, middle-aged men at the middle of the acculturation continuum have significantly higher rates of hypertension than persons at the low end of the continuum. Lower rates are also observed among men at the high end of the acculturation continuum, but these rates are not significantly lower than those among men in the middle acculturation group when other variables are controlled. These findings for middle-aged men support an "acculturative stress" model that suggests that stress is higher at the middle of the acculturation continuum. Research on the influence of acculturation on health outcomes should go beyond simply examining linear effects to investigate the viability of nonlinear effects.

Predictors of smoking among Mexican-Americans: findings from the Hispanic HANES.

BACKGROUND: This report presents findings from the Hispanic HANES on patterns and predictors of smoking in the Mexican-American subsample. Data are drawn from men and women ages 20-74 years who were administered the Adult Sample Person Questionnaire (N = 3,464). METHODS: Four smoking variables (current, ever, former, and daily consumption) are analyzed in relation to sociodemographic measures, including gender, age, marital status, employment status, occupational prestige, income, acculturation, co-workers' smoking, and presence of others in the home who smoke. All analyses were conducted separately for young, middle-age, and older age groups and for males and females. Multiple logistic and multiple regression analyses were performed, controlling for sociodemographic factors, to identify predictors of smoking. RESULTS: The most important factors found to be associated with smoking were the presence of other smokers in the immediate social environment (home and workplace) and the degree of acculturation (particularly among women). Associations with age, income, and marital status were inconsistent across age and gender groups. With minor exceptions, education, employment, and occupational prestige were unrelated to smoking. CONCLUSIONS: These findings support interventions on the basis of age categories, differential acculturation, and social influence, but overall the findings are more striking for their similarity to predictors of smoking in the general population than for their differences.

Hearing loss and hearing aid use in Hispanic adults: results from the Hispanic Health and Nutrition Examination Survey.

Data from the Hispanic Health and Nutrition Examination Survey were employed to investigate the prevalence of hearing loss and hearing aid use in Mexican-American, Cuban-American, and Puerto Rican adults. Hearing loss was 6 to 14 times more prevalent in older (ages 54 to 74) vs younger (ages 20 through 34) subjects. Cuban Americans and Mexican Americans tended to have a similar prevalence of hearing loss, whereas Puerto Ricans had markedly lower rates. Mexican-American men had higher rates of hearing loss than Mexican-American women. The prevalence of hearing aid use among hearing-impaired individuals ranged from 2% to 11%. Implications for future research are discussed.

Health care utilization barriers among Mexican Americans: evidence from HHANES 1982-84.

Data from the Hispanic Health and Nutrition Examination Survey (HHANES) conducted by the National Center for Health Statistics in 1982-1984 were analyzed to document the type of barriers encountered which prevented Mexican Americans from obtaining health care, the sociodemographic subgroups most vulnerable to such barriers, and to examine the combined effects of predisposing, enabling, and need characteristics on these barriers. The findings suggest, in general, that low income groups, younger age groups, the less acculturated, those who lack health insurance coverage, those with functional limitations, and those in poorer perceived health status encounter more barriers than others, and are prevented by these barriers from obtaining health care for themselves.

Utilization of curanderos by Mexican Americans: prevalence and predictors. Findings from HHANES 1982-84.

Data from the Southwest sample of the Hispanic Health and Nutrition Examination Survey (HHANES) were analyzed to examine whether the use of a curandero or other folk medicine practitioner hindered, enhanced, or did not affect the utilization of western health care services by Mexican Americans. Findings revealed that only 4.2 percent of the HHANES sample persons between the ages of 18-74 years reported consulting a curandero, herbalista, or other folk medicine practitioner within the 12 months prior to the survey. Income, self-perceived health status, the language of the interview, and dissatisfaction with modern medical care recently received independently predicted curandero utilization (adjusted OR 2.01 and 1.66, respectively). Low income and self-perceived health status were less strongly related to curandero utilization.

Acculturation and alcohol consumption in the Mexican American population of the southwestern United States: findings from HHANES 1982-84.

Data from the Southwestern sample of the Hispanic HANES are employed to evaluate the relationship of acculturation into the larger society with alcohol consumption. As in previous work, acculturation was not found to be related to alcohol consumption of Mexican American men, but was positively related to the consumption of younger Mexican American women. Among middle-aged women, acculturation was not important. However, we found evidence that middle-aged women might be turning to alcohol in response to marital disruption and poverty. In addition, middle-aged women who are not employed are less frequent drinkers but those who drink are heavier drinkers than employed women.

Change in subjective age among the elderly: an eight-year longitudinal study.

Changes in subjective age were investigated with a sample of older Mexican Americans and Anglos over an 8-year period (1976-1984). It was found that people who changed from youthful ("young" or "middle-aged") to old ("old" or "very old") subjective ages were significantly different than persons retaining youthful subjective ages on several factors: they were chronologically older, were more likely to be Mexican Americans, and had reported declines in their self-assessed health. These were the exact same differences observed cross-sectionally which renews faith in cross-sectional data in this area. A few people reversed their subjective ages (from old to youthful) over time, but we found no evidence that they had experienced improvements in their health or social situation.

Smoking among Mexican Americans: a three-generation study.

Smoking behavior was investigated with data from a three-generation study of Mexican Americans in San Antonio, Texas. Rates of smoking among the men were found to be higher than rates for other White men obtained in previous studies, while rates for women were slightly lower than those reported for other White women. However, the percentage of light smokers was considerably higher among Mexican Americans than among other groups. There was no evidence that acculturation was a consistent predictor of greater likelihood of smoking. However, there was evidence that the smoking behavior of younger Mexican Americans, particularly the women, was associated with the smoking behavior of their parents.

Sources of helping and intergenerational solidarity: a three-generations study of Mexican Americans.

Sources of help and advice (other than one's spouse) and degree of intergenerational solidarity were investigated in a three-generation sample of Mexican Americans. It was found that elderly Mexican Americans are involved in strong helping networks with their children who rely a great deal on them for advice and help. In all three generations, there is a predominance of family as sources of support. Women are relied on for help regarding health matters and men regarding home repairs and upkeep. Help and advice regarding financial problems and personal problems fall primarily along same-sex lines. Scales measuring intergenerational solidarity, showed that all-female dyads have greater associational solidarity than all-male and cross-sex dyads. Few differences appear in affectual solidarity which was uniformly high. Finally, there appears to be minimum association and intergenerational helping between grandparents and grandchildren.
