The immunization status of Texas children aged 3 to 24 months: results of the 1994 Texas immunization survey.

Texas has no routine system to determine current immunization levels in preschoolers. To determine the current immunization status of Texas children younger than 2 years, the Texas Department of Health commissioned a household survey in 1994. The survey included 4552 in-person interviews with parents or legal guardians of children aged 3 to 24 months. Results showed a statewide up-to-date immunization level of 55%. The younger the children, the more likely they were to be up-to-date. Differences were marked among groups based on geography, race/ethnicity, and use of public assistance. Hispanic children, children enrolled in the Women, Infants, and Children program, and children living in border communities had higher levels of immunizations. Immunization levels were below the statewide average for African-Americans, children on Aid to Families with Dependent Children, and children on Medicaid. Children with no health insurance and children with private insurance had equivalent immunization levels. Although progress appears to have been made in getting children immunized according to recommended schedules, much work remains to be done to reach our state and national goals and to protect our youngest from outbreaks of vaccine-preventable diseases.

The emerging Hispanic population: a foundation for cancer prevention and control.

Although making up only 9% of the U.S. population and concentrated in urban areas of a few states, Hispanics are found throughout the country and represent a mix of historical and cultural backgrounds. This diverse group cuts across racial and ethnic lines, with origins in various countries of Europe and North, Central, and South America. The Hispanic population has several distinguishing demographic characteristics, including its rapid growth rate, relative youth, and low educational and socioeconomic levels. However, considerable differences exist among Hispanic groups, particularly in median age, household size, education, and family income. The majority of Hispanics face barriers to health care access, including a lack of health insurance coverage, underrepresentation in health care fields, and cultural and language differences. These distinct demographic characteristics and barriers have a direct impact on the risk of cancer in Hispanics and on the development of prevention and control strategies. The purpose of this review is to examine the demographic and socioeconomic characteristics of Hispanics and issues of access to health care among this population within the context of cancer prevention and control.

Comparing acculturation scales and their relationship to cancer screening among older Mexican-American women.

BACKGROUND: Hispanic women in the United States are less likely to participate in breast and cervical cancer screening than women of other racial and ethnic groups. To plan appropriate interventions requires an understanding of the barriers to participation, including those of acculturation and assimilation. Few studies have examined the effects of acculturation and assimilation on the cancer-screening behavior of Mexican-American women. PURPOSE: Because of the extensive use of the Cuellar acculturation scale and the more recent use of the Hazuda scale, we explore the utility of these two measures to predict Pap smear and mammography screening. Using a population-based sample of Mexican-American women aged 40 years and older, we compare the two scales with each other and describe their relationship to sociodemographic factors and to participation in cancer screening. METHODS: The data are from baseline surveys in El Paso and Houston, Tex., conducted before the implementation of community interventions to improve Pap smear and mammography screening in low-income Mexican-American women. Study subjects were 923 randomly selected Mexican-American women aged 40 years and older living in 16 El Paso census tracts and seven Houston census tracts. Personal interviews solicited information on age, martial and employment status, household annual income and size, education, health insurance coverage, Pap smear and mammogram history, and a series of acculturation dimensions. Acculturation was measured using the abbreviated version of the Cuellar scale developed for the Hispanic Health and Nutrition Examination Survey, 1982-1984, and the Hazuda scale developed for the San Antonio Heart Study. The eight-item Cuellar acculturation scale assessed the extent to which Spanish and English were spoken, preferred, read, and written; the ethnic identification of the respondent and her parents; and generational status in the United States. The Hazuda scale assessed the following dimensions of acculturation: adult proficiency in English, adult pattern of English versus Spanish language usage, value placed on preserving Mexican cultural origin, attitude toward traditional family structure and sex-role organization, and adult interaction with members of mainstream society. RESULTS: The Cuellar scale was highly correlated with Hazuda's two language dimension. The Hazuda scale dimensions, Mexican cultural values and traditional family attitudes, correlated the least with Cuellar's scale. All the acculturation dimensions, Cuellar's and Hazuda's, were strongly associated with education and health insurance coverage. With the use of multiple logistic regression to adjust for education, health insurance, and other variables, English proficiency was a predictor of both a recent Pap smear and a recent mammogram. No other language-based acculturation dimension was associated with a recent screening with adjustment for education, health insurance, and other variables. However, in controlling for these factors, we found that a woman's attitude toward traditional family structure was related inversely to mammogram screening. That is, women who held the strongest traditional Mexican family attitudes were more likely to participate in mammography screening. CONCLUSION: This study shows the importance of separating the effects of acculturation on cancer screening from those due to social and economic conditions. Results suggest that the Hazuda scale provides a more multidimensional approach than the Cuellar scale and is a superior measure of the acculturation process. Traditional Mexican family attitudes positively influence mammogram-screening behavior, and this finding has implications for cancer control interventions in this population.

Effect of social networks on cancer-screening behavior of older Mexican-American women.

BACKGROUND: Previous studies have determined that Hispanic women and, in particular, Mexican-American women have the lowest rates of cancer screening of any race and ethnic group in the United States. In the development of cancer control strategies for this population, little attention has been given to factors that encourage Mexican-American women to seek cancer preventive care. Recent studies suggest that social networks can have a positive influence on cancer-screening participation. PURPOSE: We determined the extent to which differences in social networks account for variations in breast and cervical cancer-screening practices among low-income Mexican-American women. METHODS: The data analyzed in this study were obtained from a baseline survey of knowledge, attitudes, and cancer-screening practices conducted prior to implementation of community interventions designed to improve Pap smear and mammography screening in low-income Mexican-American women 40 years old and older living along the U.S.-Mexican border in El Paso County, Texas. A random selection of 1300 households served as a sampling frame to identify Mexican-American women 40 years old and older for personal interviews. Of the 549 households identified as having at least one eligible female, 450 women completed the personal interviews that provided the data for this study. Personal interviews solicited information on age, income, marital status, place of birth, education, health insurance coverage, Pap smear- and mammogram-screening practices, and six questions relating to social network. A social network score was assigned to each woman by summation of the following six variables: number of confidants, number of close friends, number of close relatives, frequency of contact with these close friends or relatives per month, church membership, and church attendance. Women were grouped into three linear strata of social network (low, medium, high) based on tertiles of the scores. Cancer-screening history was also ascertained during the interview. RESULTS: The 2-year prevalence of Pap smear and mammography use increased with social network. For each gain in social network level (low, medium, high), adjusted for sociodemographic factors, the odds ratio for Pap smear use was 1.33 (95% confidence interval = 1.02-1.73); it was 1.40 (95% confidence interval = 1.02-1.93) for mammogram use. Of the six social network components, the number of close friends was the most important predictor of mammography (P = .002) and Pap smear (P = .025) screening. CONCLUSION: Social networks appear to be an important determinant of cancer-screening behavior among low-income, older Mexican-American women.

Pap smear and mammogram screening in Mexican-American women: the effects of acculturation.

OBJECTIVES: For Mexican Americans, acculturation is a multidimensional process of adopting attitudes, values, and behavior from the non-Hispanic White culture. This study examines the effects of different dimensions of acculturation on the cancer screening behavior of Mexican-American women. METHODS: Subjects were 450 randomly selected Mexican-American women age 40 years and older living in El Paso, Texas. Personal interviews solicited information on age, income, education, health insurance, Pap smear and mammogram use, and acculturation. Acculturation was measured with five scales that assessed English proficiency, English use, value placed on culture, traditional family attitudes, and social interaction. RESULTS: The 2-year prevalence of Pap smear and mammogram screening increased with each gain in acculturation on English proficiency and use. These associations disappeared when adjusted for age, income, insurance, and education. After adjusting for sociodemographic factors and other acculturation dimensions, a strong traditional Mexican attitude toward family was positively related to mammography use. CONCLUSIONS: Taking advantage of the positive influence of Hispanic familism on cancer screening behavior may increase the effectiveness of cancer control interventions in Mexican Americans.

Oral mucosa pigment changes in heavy drinkers and smokers.

The preliminary observation that heavy drinking and smoking produced oral mucosal changes consisting of splotchy areas of depigmentation surrounded by hyperpigmentation was tested. The study population was comprised of 52 patients from an alcohol detoxification ward, who were compared with 54 patients from psychiatric inpatient and day hospital services. Structured interviewing was developed for both samples of patients who met either diagnostic criteria for alcohol abuse or dependence, or criteria for alcoholism on the Short Form of the Michigan Alcohol Screening Test, and were identified as nonsmokers or as those who smoked one to three or more packs of cigarettes a day. Photographs of the inner surface of the lips, oral mucosa, and gingivae independently were rated for severity of oral pigment change by two raters blind to a patient's alcohol or smoking history. This study demonstrates that reported observable oral pigment changes identify patients who are heavy smokers and drinkers, and may be a useful diagnostic sign.

Data-based interventions for cancer control in Texas.

The percentage of excess mortality based on the ratio of the race-ethnic-sex-specific regional rate to the state rate was used to identify regions with differing risks of lung, breast, and cervical cancer. Mortality maps show wide variation in mortality risks for these cancers not only by race and ethnicity but also by geographic region. Cancer-staging information from the State Cancer Registry indicated that excess mortality for breast and cervical cancers in black and Mexican-American women results largely from the later detection of these cancers. Together with geographic mapping of data on cancer mortality, data on the prevalence of tobacco use and on the use of Papanicolaou's tests and mammograms can be used to select and direct interventions to specific regions and to the highest risk populations. Evaluation of routinely collected cancer data, particularly in state health departments, is a primary step in implementing programs to control and prevent cancer in Texas.

Paternal occupation and anencephaly.

It has been suggested that paternal occupational exposures to pesticides and solvents increase the risk of neural tube defects in offspring. With the use of Texas livebirth, fetal death, and linked livebirth-death records, the authors conducted a population-based case-control study among 1981-1986 Texas births to examine the association between paternal occupation and anencephalic births. Fathers employed in occupations associated with solvent exposure were more likely to have offspring with anencephaly (odds ratio (OR) = 2.53), with painters having the highest risk (OR = 3.43). A lesser association was found for fathers employed in occupations involving pesticide exposure (OR = 1.28). Further studies are indicated to clarify these associations.

[Perspectives of liver transplantation in Chile].

After an initial experience with 4 patients who received orthotopic liver transplant (OLT) we analyze the perspectives of establishing liver transplantation programs in Chile. An estimated 100 adult and pediatric patients require OLT a year and no more than 3 centers are required to deal with this and acquire experience with the procedure. A national organization for organ procurement is essential, given the marked difficulties in obtaining cadaver organs at present. Each procedure has an estimated cost of $5 million with 2 more millions in the first year. Thus a program for 15 patients a year may cost $ 100 million, personnel expenses not included.

Primary liver cancer death and occupation in Texas.

A death certificate case-control study of primary liver cancer and occupation was conducted to determine if the high risk of liver cancer in Mexican-Americans can be explained by farmworker exposures to pesticides. The association of liver cancer with the petroleum and chemical industry and with other potentially high-risk occupations was also examined. For the years 1969 to 1980, 1,742 deaths from primary liver cancer were identified for Texas males. Controls were randomly selected from other causes of deaths among males excluding all neoplasms, liver and gallbladder diseases, infectious hepatitis, and alcoholism, and were frequency matched to cases by age, race, ethnicity, and year of death. Risk for farmworkers based on age, race, and ethnicity-adjusted odds ratios (ORs) was not excessive (OR = 1.4, 95% confidence limits [C.L.] 0.8-2.2) but was larger than the risk for farmers (OR = 1.0, 95% C.L. 0.8-1.2). Excess risk in the petroleum and chemical manufacturing industries was confined to oil refinery workers (OR = 2.0, 95% C.L. 1.1-3.5). Other occupations with twofold risk or greater were plumbers and pipefitters (OR = 2.0, 95% C.L. 1.0-3.8), butchers and meat cutters (OR = 2.6, 95% C.L. 1.1-6.6), textile workers (OR = 3.1, 95% C.L. 1.2-7.8), cooks (OR = 2.2, 95% C.L. 1.1-4.5), and longshoremen (OR = 2.2, 95% C.L. 0.6-7.4).

Epidemiology of anencephaly in Texas, 1981-1986.

The incidence of anencephalic births among Texas residents for the period 1981 through 1986 is described. The annual incidence of this birth defect varied from 3.8 to 4.3 cases per 10,000 total births (live births and stillbirths). The highest mean annual incidence was found in East Texas and South Texas. Within all ethnic and racial groups studied, females had higher rates of anencephaly than males, and Spanish-surnamed residents had the highest incidence of this defect, with 5.0 cases per 10,000 live births. Mothers with three or more previous live births or a history of stillbirths were more likely to have anencephalic offspring than were those without these documented histories. Differences in the incidence of anencephalic births between Spanish-surnamed and non-Spanish-surnamed whites were not explained by differences in parity.

Postmenopausal estrogen use and mortality. Results from a prospective study in a defined, homogeneous community.

The authors studied the association between postmenopausal estrogen use and mortality from cardiovascular disease, coronary heart disease, cancer, and all causes in a cohort of 1,868 women aged 50-79 years residing in a planned community. After 12 years, the age-adjusted all-cause mortality rate was lower in the 734 postmenopausal estrogen users (14.9/100 women) compared with the 1,134 nonusers (21.5/100 women) (relative risk (RR) = 0.69, 95% confidence interval (Cl) 0.55-0.87). After adjustment for age, systolic blood pressure, social class, fasting plasma cholesterol, fasting plasma glucose, Quetelet index (weight (lbs)/height (in)2 x 100), and cigarette smoking by the Cox model, the relative risk increased to 0.79 (95% Cl 0.62-1.01). Because a postmenopausal estrogen-smoking interaction term was significant (p = 0.025), separate Cox models were run for never, past, and current smokers. In never and current smokers, estrogen was protective for all-cause mortality, with relative risks of 0.67 (95% Cl 0.45-0.99) and 0.62 (95% Cl 0.39-0.98), respectively. However, past smokers were not protected by postmenopausal estrogen use (RR = 1.32, 95% Cl 0.84-2.08). Cause-specific models revealed differences in the association of postmenopausal estrogen use with cardiovascular disease mortality and coronary heart disease mortality that were dependent on smoking status. Postmenopausal estrogen use was strongly protective in current smokers but was associated with increased risk in past smokers. As expected, cancer mortality was increased in smokers. The confidence intervals for the relative risk estimate of postmenopausal estrogen use for cancer mortality in each smoking category included one. Finally, a separate analysis of subsequent three-year mortality in women surviving the first nine years of follow-up revealed reduced death rates only for women using estrogen at both baseline and nine years of follow-up, suggesting both a conservative bias in our data introduced by the large reduction in postmenopausal estrogen use during the study period and the possibility of a stronger protective effect for recent postmenopausal estrogen use.
