Characteristics of dropouts in longitudinal research on aging: a study of Mexican Americans and Anglos.

The characteristics of dropouts in a four-year longitudinal study of Mexican Americans and Anglos aged 60 years and over are investigated. Dropouts are found to be significantly older, to be less healthy, to view themselves as older, and to be less active than persons remaining in the study. Subgroups of dropouts differ from each other; deceased persons and those who could not be located were found to be generally less advantaged than restudied persons, while refusers were found to be advantaged. Implications for longitudinal studies on aging are discussed.

Epidemiology of self-reported past heavy drinking in Hispanic adults.

OBJECTIVES: Self-reports of past heavy drinking correlate with the current drinking practices and with risk of mortality in non-Hispanic males. The prevalence of past heavy drinking has not been reported in Hispanic populations. METHODS: Using data from the Hispanic Health and Nutrition Examination Survey (HHANES) we (1) report on the prevalence, duration and severity of past heavy drinking in three Hispanic groups, (2) compare the current alcohol consumption patterns among past heavy drinkers and those who do not report a history of past heavy drinking and (3) compare the risk factor profiles and health indicators in these two groups. RESULTS: The prevalence of past heavy drinking among Mexican American and Puerto Rican males ranged from 28-35% while the rates for Cuban American males ranged from 7-16%. The rates for Hispanic women were much lower (1-8%). The average years of past heavy drinking ranged from 2.3-14.9 years, while the alcohol consumption during the past heavy drinking period ranged from 24.4-44.0 drinks per week. Past heavy drinkers tended to consume more alcohol at present than did never heavy drinkers with the greatest differences found for Mexican American females. Comparisons of the risk factors and health indicators by drinking status revealed a higher prevalence of smoking among past heavy drinkers (50-60%) versus never heavy drinkers (34-43%). Past heavy drinking Mexican American females also reported significantly more chronic conditions and depressive symptoms than did never heavy drinkers. CONCLUSIONS: Prevalence rates of past heavy drinking among Mexican American and Puerto Rican males are approximately three times higher than rates reported for non-Hispanic male populations.

A test of the psychosocial vulnerability and health behavior models of hostility: results from an 11-year follow-up study of Mexican Americans.

Previous research has shown that interpersonal conflict and depression are cross-sectionally associated with hostility. Our objective was to determine whether hostility is longitudinally predictive of interpersonal distress and depression and to replicate previous research that suggests that hostility is a risk factor for other health behaviors (e.g., smoking and excessive alcohol use) and psychosocial health problems. We use data from the youngest generation of a three-generation, 11-year follow-up study of Mexican Americans, that represent 251 Mexican Americans between the ages of 18 and 42 years. Our indicator of hostility was the irritability subscale from the Buss-Durkee Hostility Inventory. After statistically controlling for marital status, language acculturation, education, age, and sex, irritability was found to predict subsequent heavy drinking, somatic symptoms associated with depression, psychosomatic symptoms, infectious disease, divorce, marital separation, ending a serious nonmarital relationship, not being married at the follow-up, and more negative feelings associated with divorce, marital separation, and ending a serious relationship. Our research supports theory and research suggesting that hostility is predictive of physical symptoms, poor health habits, and interpersonal conflict.

The association between emotional well-being and the incidence of stroke in older adults.

OBJECTIVE: Individuals with high levels of depressive symptoms have an increased risk of many illnesses, including stroke. Measures of depressive symptoms include questions about the presence of negative affect, such as sadness, as well as the absence of positive affect, such as happiness and optimism. We assessed whether positive or negative affect, or both, predicted risk of stroke. METHODS: Data were from a 6-year prospective cohort study of a population-based sample of 2478 older whites and blacks from five counties in North Carolina who reported no history of stroke at the baseline interview. Baseline, in-person interviews were conducted to gather information on sociodemographic, psychosocial, and health-related characteristics of subjects. Thereafter interviews were conducted annually for 6 years. RESULTS: Increasing scores on the modified version of the Center for Epidemiological Studies Depression Scale (CES-D) were significantly associated with stroke incidence for the overall sample (relative risk [RR] = 1.04 for each one-point increase, 95% confidence interval [CI] = 1.01-1.09) over the 6-year follow-up period after adjusting for sociodemographic characteristics, blood pressure, body mass index, smoking status, and selected chronic diseases. Positive affect score demonstrated a strong inverse association with stroke incidence (RR = 0.74, 95% CI = 0.62-0.88). CONCLUSIONS: Increasing scores on the modified CES-D are related to an increased risk of stroke, whereas high levels of positive affect seem to protect against stroke in older adults.

Physical and psychosocial consequences of stroke in elderly Mexican Americans.

OBJECTIVE: The current study examines the psychosocial and physical predictors and consequences of stroke among elderly non-institutionalized Mexican Americans. DESIGN: A cross-sectional cohort study design was used. SETTING: The sampling frame included the Southwestern United States (Arizona, California, Colorado, New Mexico and Texas) where subjects were interviewed in their homes. PARTICIPANTS: A probability sample consisted of 3,050 Mexican Americans aged 65 or older. MAIN OUTCOME MEASURE: The main outcome measure was self-report of being diagnosed by a physician as having a stroke that required hospitalization. RESULTS: Those who ever had a stroke (N=159) were less likely to be able to perform activities of daily living than persons who never had a stroke (N=2,869). Rates of disability and prevalence of stroke appear to be higher in elderly Mexican Americans than in the general elderly population. Greater education and language acculturation were risk factors for having a stroke. CONCLUSIONS: The finding that Mexican Americans who are less acculturated are more healthy suggests that acculturation may increase morbidity and, potentially, mortality from stroke.

Patterns of prescription drug utilization in elder Mexican Americans: results from the Hispanic EPESE Study. Established Population for the Epidemiologic Study of the Elderly.

The objective of this study was to determine the patterns of prescription medication usage among community-dwelling Mexican-American elders. This was a cross-sectional survey of a regional probability sample of 2,895 community-dwelling Mexican Americans, aged 65 and over. Of the sample, 58.1% used at least one prescribed medication within the two weeks prior to their participation in the study. Women were significantly more likely than men to use analgesics, non-steroidal anti-inflammatory agents, prescription nutritional supplements, and other central nervous system and endocrine medications. Subjects aged 75 and over were more likely to use cardiovascular medications, nutritional supplements, ophthalmic preparations and antihistamines, while those in the age groups 65-69 and 70-74 were more likely to use hypoglycemic and endocrine medications. Interestingly, there was a significantly decreased usage of hypoglycemic medications in the older age group (aged 75 and over) as compared with the younger age groups (65-69 and 69-74). This may indicate that Mexican American elders are dying at younger ages from complications related to diabetes mellitus and are not alive to use hypoglycemic medications at ages 75 and over. Also, men used more hypoglycemic medication than women (77% vs 70%). There was no relationship between use of medication and severity of diabetic illness.

The health of Hispanics in the southwestern United States: an epidemiologic paradox.

Recent reports in the literature on the health status of southwestern Hispanics, most of whom are Mexican Americans, are reviewed critically. The review is organized into the following sections: infant mortality, mortality at other ages, cardiovascular diseases, cancer, diabetes, other diseases, interview data on physical health, and mental health. Despite methodological limitations of much of the research, it can be concluded with some certainty that the health status of Hispanics in the Southwest is much more similar to the health status of other whites than that of blacks although socioeconomically, the status of Hispanics is closer to that of blacks. This observation is supported by evidence on such key health indicators as infant mortality, life-expectancy, mortality from cardiovascular diseases, mortality from major types of cancer, and measures of functional health. On other health indicators, such as diabetes and infectious and parasitic diseases, Hispanics appear to be clearly disadvantaged relative to other whites. Factors explaining the relative advantages or disadvantages of Hispanics include cultural practices, family supports, selective migration, diet, and genetic heritage. The recently completed Hispanic Health and Nutrition Examination Survey will go a long way to provide answers to many questions regarding the health of Hispanics in the Southwest or elsewhere.

Mortality among minority populations: a review of recent patterns and trends.

The mortality experiences of blacks, Native Americans, and Hispanics are reviewed. Evidence recently made available shows the Hispanic experience to be only slightly less favorable than the Anglo (other white) experience, suggesting remarkable progress in recent years. Native Americans have also made remarkable progress in recent years, especially in reducing infant mortality. Blacks have shown less improvement than the other two groups. Reasons for these trends, for differences among the groups in mortality rates and life expectancy, and for patterns of mortality by cause are discussed.
