[Children of immigration: effects of their presence on the demographic situation in selected employment countries].

The author examines the impact of migrant workers in Europe on such demographic developments as declining fertility, population decrease, and demographic aging. Official government and U.N. data are used to contrast age distributions of migrant and native populations in selected receiving countries in Europe. "In his analysis of the impact of second-generation migrants on demographic development in the principal European employment countries, the author shows that in all of these countries the foreign population improves the age distribution of the population as a whole by way of reinforcing the weight of the younger age groups in relation to the older groups. The ageing of the national populations...is thus countered by the presence of second-generation migrants." (summary in ENG)

Technological change and the demographic transition model--India, a case study.

The concept of the demographic transition is re-examined in the context of India with particular reference to the demographic impact of technological change. In particular, the author examines whether "the demographic effects of a developing capitalist economy are due to (a) the extent of capitalist transformation of an economy; and (b) the nature and level of imported technological change."

Effects of consanguinity on pre-reproductive mortality: does demographic transition matter?

The aim of this study was to investigate whether there is an increase on premature deaths due to genetically determined factors at the beginning of a demographic transition. We also analyzed the effects of parental consanguinity on offspring mortality from an epidemiological viewpoint, using parish records for family reconstitution in a Basque population (1800-1990). Among the offspring of unrelated parents, 13.1% died before their first year of life (infant mortality), and 22.8% died before the age of 16 (pre-reproductive mortality). Significant increases in both infant (23.6%) and pre-reproductive (38.5%) deaths were found among the progeny of first cousins or closer relatives, 1C (F > or = 0.0625). The corresponding relative risks of mortality were 1.79 (95% confidence limits: 1.37-2.28) and 1.68 (1.38-2.01), respectively. Estimates of the population attributable risks indicate that 4% of pre-reproductive mortality is ascribable to consanguineous unions, although kinships other than 1C produced only slight increases in offspring mortality. Evidence on the relationship between the demographic transition and the increase in premature deaths due to genetic factors was obtained through a principal component analysis (95.1% of variance accounted for). During the initial stages of the demographic transition, the population experienced substantial elevations in mean family size, natural increase of the population, frequency of close consanguineous matings (1C), and death rate due to congenital anomalies and perinatal diseases. These findings are of interest for the health services of many developing societies in Asia, Africa, and Latin America, which are nowadays immersed in the demographic transition process.

Clinical and demographic determinants of heart rate variability in patients post myocardial infarction: insights from the cardiac arrhythmia suppression trial (CAST).

BACKGROUND: Clinical and demographic determinants of heart rate variability (HRV), an almost universal predictor of increased mortality, have not been systematically investigated in patients post myocardial infarction (MI). HYPOTHESIS: The study was undertaken to evaluate the relationship between pretreatment clinical and demographic variables and HRV in the Cardiac Arrhythmia Suppression Trial (CAST). METHODS: CAST patients were post MI and had > or =6 ventricular premature complexes/h on pretreatment recording. Patients in this substudy (n = 769) had usable pretreatment and suppression tapes and were successfully randomized on the first antiarrhythmic treatment. Tapes were rescanned; only time domain HRV was reported because many tapes lacked the calibrated timing signal needed for accurate frequency domain analysis. Independent predictors of HRV were determined by stepwise selection. RESULTS: Coronary artery bypass graft surgery (CABG) after the qualifying MI was the strongest determinant of HRV. The markedly decreased HRV associated with CABG was not associated with increased mortality. Ejection fraction and diabetes were also independent predictors of HRV. Other predictors for some indices of HRV included beta-blocker use, gender, time from MI to Holter, history of CABG before the qualifying MI, and systolic blood pressure. Decreased HRV did not predict mortality for the entire group. For patients without CABG or diabetes, decreased standard deviation of all NN intervals (SDANN) predicted mortality. Clinical and demographic factors accounted for 31% of the variance in the average of normal-to-normal intervals (AVGNN) and 13-26% of the variance in other HRV indices. CONCLUSIONS: Heart rate variability post MI is largely independent of clinical and demographic factors. Antecedent CABG dramatically reduces HRV. Recognition of this is necessary to prevent misclassification of risk in patients post infarct.

Prognostic impact of demographic factors and clinical features on the mode of death in high-risk patients after myocardial infarction--a combined analysis from multicenter trials.

BACKGROUND: Contemporary information is lacking on the effect of demographic features and clinical features on the specific mode of mortality after myocardial infarction (MI) in the thrombolytic era. HYPOTHESIS: The aims of this study were (1) to examine the risk and trend of a different mode of mortality (i.e., all-cause, arrhythmic, and nonarrhythmic cardiac mortality) in high-risk patients post MI with reduced left ventricular ejection fraction (LVEF) or ventricular arrhythmias; and (2) to assess the predictive value of demographic and clinical variables in the prediction of specific modes of death in high-risk patients post MI in the thrombolytic era. METHODS: In all, 3,431 patients receiving placebo (2,700 men, median age 64 +/- 11 years) from the EMIAT, CAMIAT, SWORD, TRACE, and DIAMOND-MI studies, with LVEF < 40% or ventricular arrhythmia were pooled. Risk factors for mortality among patients surviving > or = 45 days after MI up to 2 years were examined using Cox regression. Short-term survival (from onset of MI to Day 44 after MI) was also examined for TRACE and DIAMOND-MI, in which patients were recruited within 2 weeks of MI. RESULTS: After adjustment for treatment and study effects, age, previous MI/angina, increased heart rate, and higher New York Heart Association functional class increased the risk of all-cause, arrhythmic, and cardiac mortality. Male gender, history of hypertension, low baseline systolic blood pressure, and Q wave were predictive of all-cause and arrhythmic mortality, whereas diabetes was only predictive of all-cause mortality. Smoking habit and atrial fibrillation had no prognostic value. Similar parameters were also predictive of short-term mortality, but not identical. CONCLUSIONS: Our study has shown that in high-risk patients post MI, who have been preselected using LVEF or frequent ventricular premature beats, demographic and clinical features are powerful predictors of mortality in the thrombolytic era. We propose that demographic and clinical factors should be considered when designing risk stratification or survival studies, or when identifying high-risk patients for prophylactic implantable cardiodefibrillator therapy.

Do personal and societal preferences differ by socio-demographic group?

For equity, preferences used in cost-effectiveness analyses (CEAs) should yield similar values for different groups with similar health states. We used data from the US 2000 Medical Expenditure Panel Survey, including socio-demographics, EQ-5D Index and EQ Visual Analog Scale (EQ VAS) scores, to examine whether EQ-5D Index (representing community preferences) and EQ VAS (representing personal preferences) scores differed systematically by socio-demographic group. Differences between EQ-5D Index and EQ VAS scores by socio-demographic group were small and mostly not statistically significant. These preliminary findings suggest that using the EQ-5D Index in CEAs may not contribute to socio-demographic inequities.

Consequences for hospitals resulting from demographic, social and morbidity changes: a European perspective.

The last 40 years has been a time of rapid demographic, social and economic change in most countries of the world. In Europe, the ageing of the population, a decrease in household size, and the reduced importance of parasitic and infectious diseases along with an increase in chronic and degenerative diseases are some of the most notable results of industrialization, urbanization and medical progress. These developments lead to changing demands not only for the services of hospitals but upon the health care system at large. Most recently, and in addition, these changes have had to be faced under resource constraints resulting from decreased economic growth. This article focuses on the similarities and differences within and across the health care systems of European countries, and on their efforts to respond to the changes which have taken place and are likely to continue in the near future. In so doing, it relates the various demographic, social and economic changes taking place in these countries to the structural changes noticeable in the hospital sector. The results obtained by statistical analyses of empirical evidence lead us to conclude that demographic and social variables may better explain the differences in hospital use within a given country over longer stretches of time than across countries at a given point in time. In the latter case, economic variables--differences in gross domestic product (GDP) per capita--serve as major explanations of the cross-country differences found. Changes in demographic, social and morbidity factors are also mirrored in the relative importance of hospital departments, at a given point in time and also in changes over time. Major changes have taken place within the health care systems. Hospitals are losing ground to other forms of health care: for instance, to institutions providing pre-hospital and post-hospital treatment. The need for more caring patterns of service, rather than for more curing, accounts for yet another overall trend. Hospitals have started to respond to this need by offering more 'semi-stationary' and part-time health care facilities. These developments go hand in hand with the establishment of closer relations between hospitals and other facilities within the health care system, and with improved non-stationary health care services.

Effects of socio-demographic variables on health-related quality of life determined by the quality of life index--German version.

STUDY OBJECTIVE: The purpose of this study was to determine subjective health-related quality of life (HRQoL) in a sample of the Austrian population over 14 years of age in order to evaluate the effect of socio-demographic variables on HRQoL. DESIGN/SETTING: HRQoL was determined by means of the quality of life index-German version (QLI-Ge). The influence of socio-demographic variables on HRQoL was assessed by statistical analysis using the Kruskal-Wallis test and an analysis of variance. PARTICIPANTS: A random-quota procedure was used to get balanced representation from regions and demographic groups of the Austrian population. The sample consisted of 1049 participants, 493 men and 556 women. MAIN RESULTS: Age was found to influence the QLI-Ge total score (index score) and most individual items, with increasing age resulting in a decrease in HRQoL. Differences between the sexes were observed in three dimensions: males scored higher in 'physical well-being', 'psychological well-being' and 'occupational functioning'. Marital status impacted most items with married persons showing better values than divorced persons or singles. Profession had only a minor effect on HRQoL, the level of education showed no influence at all. CONCLUSIONS: The socio-demographic variables age, sex and objective living conditions had a major influence on subjectively rated HRQoL, whereas profession and education were found to play a minor role in this context. It is recommended that in the interpretation of studies assessing HRQoL the above-mentioned objective factors be considered. This will be of particular importance when determining the effect of a pharmacotherapy on HRQoL in patients.

Exploring the utility of demographic data and vaccination history data in the deduplication of immunization registry patient records.

Duplicate patient records pose a major problem for many immunization registries, as well as for many electronic patient record systems. This paper reports two complementary studies exploring the deduplication of immunization registry records. One study explores the utility of different demographic data elements, singly and in combination, to assist in the deduplication process. The second study explores how clinical patient data (vaccination history data) might assist in this process. To assess the utility of demographic data elements, data were used from three registries after duplicates had been identified. A computer program, IMM/Scan, was written to count the number of true-positive (TP) matches and false-positive (FP) matches found when using different Boolean combinations of demographic data elements. In this study, a strategy of "ORing high value ANDed pairs of data elements" appeared to be most powerful. To assess the utility of vaccination history data, record pairs were drawn from 440,000 patient records. Two metrics on patient history were tested: (1) the number of identical doses shared by two records, and (2) the number of "extra" doses in the combined history of two records. In this study, sample findings include: (1) for pairs of nonduplicate records, 93% had no identical doses and 90.6% had "extra" doses, and (2) for pairs of duplicate records, 83.8% had one or more identical doses and 82% contained no "extra" doses. These studies demonstrate potentially useful approaches to using demographic data and patient history data to assist the automated deduplication of immunization patient records.

Behaviors of treated hypertensive patients and patient demographic characteristics.

The relationships between self-reported hypertension-related patient behaviors and patient demographic characteristics were examined in a sample of 2,044 patients being treated for hypertension in 111 primary care medical practices. The patient behaviors of sodium intake, weight, alcohol, exercise, relaxation and adherence to medication regimen could be predicted to some extent by patient demographic characteristics. Whether patients recalled receiving advice from their physicians about these behaviors could also be predicted by patient demographic characteristics. Patients demographically similar to physicians, i.e., male, younger, more educated and White, reported receiving more advice from their physicians. Patients with behavioral problems who received relatively less advice from their physicians included: less educated younger patients whose sodium intake was relatively high; younger and less educated over-weight women; overweight Black patients; and older women who exercised less than average.

[Plato: forerunner of demographic thinking?].

Since Malthus, several commentators have noted quantitative considerations in Plato's work, regarding him as a forerunner of demographic thinking. But how to explain several demographic contradictions between the Laws and the Republic? This paper brings out the consistency of Plato's thought, which cannot be demonstrated at a purely demographic level. His fascination for mathematics and the influence of the Pythagorean school should 1st be taken into account. However, the City, as an ideal concept and as a concrete social organization is the key to Plato's thought. Confronted with a basic problem of political philosophy, that of [power and justice, Plato proposed to restore the harmony between the City as a political body and the individual citizens. Hence policy measures which we regard unduly as eugenic and demographic, are in fact based on a conception of man quite different from ours.

Trends in the percentage of women who received no prenatal care in the United States, 1980-1992: contributions of the demographic and risk effects.

OBJECTIVE: To determine if the increase in the percentage of women who received no prenatal care in the United States relative to 1980 (from 1.3% in 1980 to 2.2% in 1989 and 1.7% in 1992) was due to increasing risks of no care in subgroups of women or increasing percentages of births to women at high demographic risk of no care. METHODS: We analyzed U.S. birth certificates for the period 1980-1992. The annual adjusted odds of no prenatal care relative to 1980 were computed by logistic regression models that included year, maternal characteristics, and interactions of these characteristics with year. We also examined changes in the annual distributions of births by maternal characteristics. RESULTS: The risk of no prenatal care in most subgroups increased during the early 1980s, peaked in the late 1980s, and declined thereafter. For example, among black women, the adjusted risk of no care more than doubled from 1980 to 1989. Throughout the 1980s and into the 1990s, the percentage of births to women at high demographic risk of no care increased. This increase in the percentage of births to women at high demographic risk shows no sign of abating. CONCLUSIONS: During the 1980s, increasing risks in subgroups of women drove the increase in the crude rate of no prenatal care. Despite decreases in the risks of no care in the early 1990s, increasing percentages of births to women with high demographic risk for no care prevented a decrease in the crude rate to the 1980 level.

Interaction between the socio-demographic variables of physicians and their patients: its impact upon patient satisfaction.

An investigation of resident physician socio-demographic characteristics and how they may interact with patient socio-demographic characteristics to influence satisfaction was done. Physician characteristics of gender, age, marital and parental status, ethnic background, level of training and demonstrated cognitive skills, was compared with similar patient socio-demographics, to ascertain if a patient's preconceived images of who a physician is, rather than what a physician does will impact significantly upon patient satisfaction outcome. Results suggest that patients make these judgments separately from physician socio-demographic variables and support the belief that communication skills are a major determinant of patient satisfaction.

Psychosocial and demographic correlates of temporomandibular disorders and related symptoms: an assessment of community and clinical findings.

This study investigated the factor structure and relative prevalence of temporomandibular disorder (TMD) symptoms, in relation to demographic and psychosocial variables in a community sample. Two empirically distinct clusters of TMD symptoms were identified. Similar to reports of TMD clinic patients, more symptoms were reported by females than males and the greatest symptom prevalence was found in subjects between the ages of 30 and 49 years. Further, the number of symptoms reported was significantly and linearly related to scores on depression and repression-sensitization scales. These relationships, however, were similar for both sets of symptom composites even though one composite is clearly identifiable as the core TMD symptoms and the second composite consists of peripheral symptoms. Since the two symptom composites share some common variance, the relationship between demographic and psychosocial characteristics and the number of composite I and composite II symptoms was examined while controlling for the presence of symptoms from the other composite. When controlling for the presence of composite II symptoms, the correlations between psychosocial and demographic characteristics and composite I symptoms are small. When the presence of composite I symptoms is controlled there is little change in the magnitude of the correlations between psychosocial and demographic characteristics and composite II symptoms. It is concluded that the psychosocial profile described in clinical research is actually more characteristic of individuals with pain/dysfunction symptoms other than the classic TMD symptoms and that the relationship between core TMD symptoms (composite I) is largely spurious. It is suggested that this psychosocial profile of TMD patients may have developed through associating certain psychosocial characteristics with TMD while such characteristics are actually present in TMD clinic patients because of the covariation of the two symptom composites in individuals seeking treatment in TMD clinics.

Identification of work disability in rheumatoid arthritis: physical, radiographic and laboratory variables do not add explanatory power to demographic and functional variables.

Work disability, a common problem in rheumatoid arthritis (RA), is known to be associated with demographic variables such as occupation, age, and formal education, as well as with disease duration. However, physical, radiographic and laboratory variables, which are included in the traditional "medical model" of work disability and collected routinely in the application process, have not been studied for their capacity to explain whether patients are working or receiving work disability payments. A cross-sectional database which included an extensively characterized group of patients with RA was examined to determine possible associations of demographic, functional, physical, radiographic and laboratory variables with work disability status. All these variables differed in patients who were receiving work disability payments and those who were working full time, but in multivariate analyses, work or disability status was best identified by demographic and functional variables. Physical, radiographic, and laboratory data did not add significantly to explanation of work disability status beyond the demographic and functional variables and disease duration, despite the fact that receipt of disability payments was used as the criterion for work disability status.

An assessment of the usefulness of demographic data provided by surrogate respondents in a case-control study of Parkinson's disease.

This study, based upon data from 40 non-demented Parkinson's disease cases and 101 community controls, and similar data provided by either the spouse (n = 110) or an adult child (n = 31) of each index subject, attempted to assess the usefulness of various demographic data provided by the surrogate respondents for the index subjects. The data were collected by personal interview using a structured questionnaire specifically developed for this study. Ninety-one percent of the index subjects and their surrogates provided information on the annual family income and 98% provided other demographic information. The analysis was done by three groups: the case-surrogates, the control-surrogates and the combined index subject-surrogates, and within each group by the two types of surrogates for the index subjects: the spouse vs adult child. The overall percent agreement between the index subjects and their surrogates varied from moderate for annual family income (54.1%), to good for educational level (61.6%) and to excellent for ethnic origin (82.6%), for age +/- 1 year (97.9%) and for marital status (100.0%). No significant differences in agreement were found for any of these demographic variables either between the case-surrogate group and the control-surrogate group, or between the spouse surrogates and the child surrogates. These findings suggest that spouses and adult children can provide valid information and are equally reliable informants concerning the demographic characteristics of index subjects in a case-control study of Parkinson's disease and, possibly, of other diseases.

An exploration of the demographic and social correlates of criminal behavior among adolescent males.

PURPOSE: This paper describes an investigation into the demographic and sociologic characteristics of male adolescent ages 15-18 years in a youth detention center as a result of delinquent behaviors. The intent of the study was to determine which characteristics were correlated with a high severity of criminal behaviors. METHODS: A descriptive survey research design was used with self-scored questionnaires distributed to 201 adolescent males in a youth detention center in a metropolitan southeastern city with a population of 907,000. Subgroups were created based on the severity of crime committed and whether or not the adolescent was a gang member. Chi-square and Student's t-tests were used to examine differences in the demographic and sociologic characteristics of subgroups. RESULTS: When demographic and social characteristics were assessed, adolescents who reported committing more serious crimes also reported more problem behaviors (p = .001) than those who committed less serious crimes. Adolescents who reported a higher number of arrests also reported more school, social, personal, and family problems. Those who were gang members reported more school problems, were arrested more often, and committed more serious crimes than nongang members. CONCLUSIONS: Given the current emphasis on prevention, findings from this study indicate intervention programs must be directed at a combination of demographic and sociologic risk factors. Exploration of whether gang membership might be used for constructive purposes is justified.

Demographics and macroeconomic effects in aesthetic surgery in the UK.

Media interest in aesthetic surgery is substantial and suggestions of demographic changes such as reductions in age or an increase in the number of male patients are common. In spite of this, there is no peer reviewed literature reporting demographics of a contemporary large patient cohort or of the effect of macroeconomic indicators on aesthetic surgery in the UK. In this study, computer records 13006 patients presenting between 1998 and the first quarter of 2003 at a significant aesthetic surgery centre were analysed for procedures undergone, patient age and sex. Male to female ratios for each procedure were calculated and a comparison was made between unit activity and macroeconomic indicators. The results showed that there has been no significant demographic change in the procedures studied with patient age and male to female ratio remaining constant throughout the period studied for each procedure. Comparison with macroeconomic indicators suggested increasing demand for aesthetic surgery in spite of a global recession. In conclusion, media reports of large scale demographic shifts in aesthetic surgery patients are exaggerated. The stability of unit activity in spite of falling national economic indicators suggested that some units in the UK might be relatively immune to economic vagaries. The implications for training are discussed.
