ISOLATION, INTEGRATION, AND ETHNIC BOUNDARIES IN RURAL GUATEMALA

We investigate two perspectives about the effects of reduced discrimination and greater social and economic opportunities on ethnic identity in rural areas of contemporary Guatemala. Our analysis contrasts the effects of new opportunities in Indigenous communities on language use and dress, using data from the 1995 Encuesta Guatemalteca de Salud Familiar (EGSF). While the use of both dress and language has changed substantially in recent years, language use has changed considerably more than dress. We conclude that, in this context, economic opportunities have not necessarily diminished ethnic solidarity, but may have instead reshaped it.     

The age at first birth and timing of the second in Costa Rica and Guatemala

This paper explores the relationship between the age at first birth and the timing of subsequent fertility in Costa Rica and in four rural villages and two urban areas of Guatemala. The results indicate that, for Costa Rica, the age at first birth is significantly related to the tempo of subsequent births, and that this association, at least for the interval to second birth, remains significant when socio-economic factors and marital status at the time of first birth are held constant. While the results suggest that the age at first birth is related to timing of the second in the Guatemalan sample as well, the association is weaker and less consistent than in Costa Rica.     

Family and neighborhood sources of socioeconomic inequality in children’s achievement

We examined family and neighborhood sources of socioeconomic inequality in children’s reading and mathematics achievement using data from the 2000–2001 Los Angeles Family and Neighborhood Survey. To describe inequality in achievement scores, we used Gini coefficients and concentration indices and multilevel regression models. We found no inequality in children’s achievement by family income when other variables in the model were held constant. Mother’s reading scores and average neighborhood levels of income accounted for the largest proportion of inequality in children’s achievement. Neighborhood economic status appears to be strongly associated with children’s skills acquisition.     

Calculation of life tables from survey data: A technical note

Life table calculations from survey data are frequently based on events for which exact dates are not available. When these dates are coded in monthly form (e.g., century months), estimates should take into account the fact that the first duration interval—the interval which captures events occurring in the first month of exposure—is half the length of all remaining intervals. Although failure to do so has a trivial effect on many demographic calculations, estimates which are based on events which occur with high frequency in the first few months of exposure can be substantially biased. Estimates offecundability for four countries in the World Fertility Survey are used to illustrate this bias.     

The Consequences of Migration to the United States for Short-Term Changes in the Health of Mexican Immigrants

Although many studies have attempted to examine the consequences of Mexico-U.S. migration for Mexican immigrants’ health, few have had adequate data to generate the appropriate comparisons. In this article, we use data from two waves of the Mexican Family Life Survey (MxFLS) to compare the health of current migrants from Mexico with those of earlier migrants and nonmigrants. Because the longitudinal data permit us to examine short-term changes in health status subsequent to the baseline survey for current migrants and for Mexican residents, as well as to control for the potential health selectivity of migrants, the results provide a clearer picture of the consequences of immigration for Mexican migrant health than have previous studies. Our findings demonstrate that current migrants are more likely to experience recent changes in health status—both improvements and declines—than either earlier migrants or nonmigrants. The net effect, however, is a decline in health for current migrants: compared with never migrants, the health of current migrants is much more likely to have declined in the year or two since migration and not significantly more likely to have improved. Thus, it appears that the migration process itself and/or the experiences of the immediate post-migration period detrimentally affect Mexican immigrants’ health.     

Employment status, psychiatric disability and quality of life: comparison of men and women with schizophrenia in Malaysia

This study explores the association between employment opportunities, psychiatric disability and quality of life of male and female patients with schizophrenia. The data were collected from 100 male and 100 female patients and their primary caregivers through personal interviews. The Disability Assessment Schedule and the Quality of Life Interview were used to collect the data. The results of the present study indicate that a large number of both the men and women were unemployed, although they suffered from only mild psychotic symptoms and had no or only minimum psychiatric disability. However, in almost all areas and levels of psychiatric disability, a significantly higher number of men than women were employed. However, the subjective Quality of Life of the employed men was significantly lower than that of the unemployed. Keeping in mind these two results, the present study argues that there is minimal community recognition in Malaysia for the employment potential of people with schizophrenia. The study also argues that policy makers must legislate to create more appropriate workplaces for the mentally ill. People with schizophrenia are entitled to just and fair treatment, and workplaces should be made attractive to them.     

Long-term low-dose dehydroepiandrosterone replacement therapy in aging males with partial androgen deficiency

Dehydroepiandrosterone (DHEA) and dehydroepiandrosterone sulfate (DHEAS) age-related withdrawal is very likely to be involved in the aging process and the onset of age-related diseases, giving rise to the question of whether preventing or compensating the decline of these steroids may have endocrine and clinical benefits. The aim of the present trial was to evaluate the endocrine, neuroendocrine and clinical consequences of a long-term (1 year), low-dose (25?mg/day) replacement therapy in a group of aging men who presented the clinical characteristics of partial androgen deficiency (PADAM). Circulating DHEA, DHEAS, androstenedione, total testosterone and free testosterone, dihydrotestosterone (DHT), progesterone, 17-hydroxyprogesterone, allopregnanolone, estrone, estradiol, sex hormone binding globulin (SHBG), cortisol, follicle stimulating hormone (FSH), luteinizing hormone (LH), growth hormone (GH) and insulin-like growth factor 1 (IGF-1) levels were evaluated monthly to assess the endocrine effects of the therapy, while β-endorphin values were used as a marker of the neuroendocrine effects. A Kupperman questionnaire was performed to evaluate the subjective symptoms before and after treatment.

The results showed a great modification of the endocrine profile; with the exception of cortisol levels, which remained unchanged, DHEA, DHEAS, androstenedione, total and free testosterone, DHT, progesterone, 17-hydroxyprogesterone, estrone, estradiol, GH, IGF-1 and β-endorphin levels increased significantly with respect to baseline values, while FSH, LH and SHBG levels showed a significant decrease. The Kupperman score indicated a progressive improvement in mood, fatigue and joint pain.

In conclusion, the present study demonstrates that 25?mg/day of DHEA is able to cause significant changes in the hormonal profile and clinical symptoms and can counteract the age-related decline of endocrine and neuroendocrine functions. Restoring DHEA levels to young adult values seems to benefit the age-related decline in physiological functions but, however promising, placebo-controlled trials are required to confirm these preliminary results.     

Ethnicity,Language, and Economic Well‐being in Rural Guatemala

Abstract We examine ethnic differences in objective and perceived economic well‐being in rural Guatemala. The evidence shows that long‐standing ethnic differentials in objective indicators of household economic well‐being actually widened between 1988 and 1995, a period characterized by rapid economic growth rates. We examine the effects of a major determinant of household economic well‐being in rural Guatemala, educational attainment, in accounting for ethnic and language differentials in household consumption. Our results show that returns to education appear to be substantially lower for indigenous households, especially indigenous households where the head of household does not speak Spanish. Ethnic differentials in perceived economic well‐being do not strictly parallel differences in objective indicators of well‐being. Indigenous women with any education are more likely to report relative economic deprivation than are non‐indigenous women, or ladinas, controlling for objective measures of household wealth.     

Voluntary childlessness: A review of the evidence and implications

This paper reviews evidence on the incidence, correlates, and implications of voluntary childlessness in the United States. Overall, the evidence points toward the increasing prevalence of this phenomenon, with some analysts projecting that as much as 30 percent of recent cohorts of American women will remain permanently childless. These high rates are shown to be similar in magnitude to rates of childlessness projected for recent cohorts of women in several European countries with fertility patterns comparable to those of the United States. Explanations for the increasing prevalence of childlessness are also considered. The second half of this paper examines existing evidence on the correlates of voluntary childlessness. In this connection, special attention is paid to education, area of residence, labor force status, income, and geographic mobility. This section also explores the implications of increasing childlessness and selected ways to redistribute the cost of children.
