Women brothel workers and occupational health risks.
(57/715)
STUDY OBJECTIVES: This study examined working conditions, reported morbidity, symptoms of post-traumatic stress disorder (PTSD) and depression and their relation to an index of occupational health risk among women working in brothels in Israel. DESIGN: Personal structured interviews with a scale of occupational risk that included seven self report items reflecting past and present morbidity and symptoms. PARTICIPANTS AND SETTING: A purposive sample of 55 women in three cities in Israel, between the ages of 18-38. MAIN RESULTS: Most (82%) women were trafficked into Israel to work illegally in prostitution, effectively deriving them of access to discretionary health care. A third of the sample (32%) had a high score (between 3 to 6) on the index of occupational risk factors. A high score was not related to recent physician or gynaecological visits and was more common among illegal workers than those with residence status. A set of regression analyses showed that the most significant predictors of reporting a high level of occupational risk symptoms were starting sex work at an early age, the number of hours worked in a day, a history of suicide attempts and PTSD symptoms. CONCLUSIONS: High occupational risk was found to be unrelated to recent physician or gynaecological visits, indicating that these visits were most probably controlled by the brothel owners and not by medical need as perceived by the women themselves. Furthermore, occupational risk factors were associated with some of the working and background conditions reported by women brothel workers. There is an urgent need for medical care for this high risk group. (+info)
The intergenerational effects of fetal programming: non-genomic mechanisms for the inheritance of low birth weight and cardiovascular risk.
(58/715)
Many epidemiological studies in diverse populations have demonstrated a link between low birth weight and subsequent disease. This evidence has given rise to the fetal origins hypothesis, which suggests that exposure of the fetus to an adverse environment in utero leads to permanent programming of tIssue function and a risk of cardiovascular disease. An alternative hypothesis is that low birth weight and adult cardiovascular disease are independent features of a genetic predisposition to cardiovascular disease. This review describes evidence that the programming phenomenon may not be limited to the first generation offspring. Results of human and animal studies identify intergenerational programmed effects on both birth weight and cardiovascular disease. This may represent a mechanism for the non-genetic inheritance of a predisposition to low birth weight and adverse cardiovascular risk across a number of generations. (+info)
Bone mineral status in immigrant Indo-Asian women.
(59/715)
BACKGROUND: Indo-Asian immigrants are known to be at high risk of metabolic bone disease, but the prevalence of osteoporosis in this population is unknown. AIM: To compare the bone mineral at the lumbar spine and femoral neck of Indo-Asian immigrant women with that of age-matched Caucasian women. DESIGN: Retrospective analysis. METHODS: Women of Indo-Asian origin referred for bone density scans in the last five years were identified. The skeletal status of each was compared with an age-matched Caucasian control for bone mineral content (BMC), bone mineral density (BMD) and bone mineral apparent density (BMAD) at the lumbar spine and femoral neck, and hip axis length was measured. RESULTS: At the lumbar spine, Indo-Asians had a significantly lower BMD than Caucasians (0.834 vs. 0.913, p = 0.008), but there was no significant difference when BMAD values were calculated (0.123 vs. 0.122). At the femoral neck, there was no difference in BMD (0.728 vs. 0.712, p = 0.5), and BMAD values were significantly higher among Indo-Asians than Caucasians (0.393 vs. 0.319, p = 0.022). Hip axis length was significantly shorter among Indo-Asian women (10.3 vs. 10.7, p = 0.009). DISCUSSION: Although Indo-Asian women appear to have lower spinal BMD than Caucasians, these differences disappear when BMAD values are calculated. While BMD is an areal density, not taking into account the 'depth' of the bone, BMAD is an estimation of volumetric density. Hence lower BMD values in Asians may be a size-related artefact. Longitudinal studies may be required to evaluate the use of BMD as a marker for fracture risk in this population. (+info)
Vlax Roma history: what do coalescent-based methods tell us?
(60/715)
Three coalescent-based methods allowed us to infer some aspects of the history of three Bulgarian Gypsies populations belonging to the Vlax linguistic group: the Lom, Rudari and Kalderas. We used several kinds of genetic markers: HV1 sequences of the maternally inherited mitochondrial genome and microsatellites of the paternally inherited Y chromosome and of the biparentally inherited chromosome 8. This allowed us to infer several parameters for men and women: the splitting order of the populations and the ages of the splitting events, the growth rate in each population and the migration rates between populations. Altogether, they enabled us to infer a demographic scenario that could explain the genetic diversity of Vlax Roma: recent splits occurring after the arrival in Europe, asymmetric migration flows especially for males and unequal growth rates. This represents a considerable contribution to the Vlax Roma history in comparison with the inferences from classical population genetics. (+info)
Introduced Plasmodium vivax malaria in a Bolivian community at an elevation of 2,300 meters.
(61/715)
Tuntunani, Bolivia, a community of 199 persons situated at an elevation of 2,300 meters, experienced its first malaria outbreak in 1998. Blood smears from 63 of 183 symptomatic residents were examined, and 52 showed Plasmodium vivax. An investigation two years later indicated that the epidemic resulted from introduced transmission, since persons of all ages and both sexes were infected, and there had been no travel to low-lying endemic areas in the five months preceding the epidemic. Treatment became available only two months into the epidemic, at which time 58% of the people had been ill for three weeks or longer. This outbreak demonstrates the vulnerability of highland populations with poor access to health care to introduced malaria. (+info)
Factors affecting interstate use of inpatient care by Medicare beneficiaries.
(62/715)
This article examines the extent to which interstate inflow and outflow of patients affects their observed use of Medicare Part A inpatient care. Interstate patient flow can bias utilization rates and may be due to seasonal migration, interstate inpatient care market areas, or purposive seeking of specialized/high-quality care. Examination of state level patient flow data drawn from 1987 Medicare discharge indicate that most interstate patient flow occurs between adjacent states probably as an outgrowth of interstate markets. Regression analyses of patient flow data suggest that while seasonal migration is an important determinant of patient flow, its importance is secondary to that of indicators of the availability of specialized services. These findings suggest research questions that may be best answered in detailed analyses of inpatient utilization in interstate market areas and seasonal migration. (+info)
Prevention of HIV infection among migrant population groups in Northeast Brazil.
(63/715)
HIV infection is spreading among the poor, women, and migrant communities in the interior of Northeast Brazil. The research focused on different configurations, beliefs, representations, and forms of social organization of behavior thought to be associated with the population's capacity to efficiently follow AIDS prevention measures. Participants located in neighborhoods known for having large migrant populations were identified by Family Health Program Workers in Fortaleza and Teresina. The study adopted a qualitative methodology. Several belief-system concepts and values, as well as the social organization of sexuality revealed in the study, represent obstacles both to AIDS prevention and condom use. Hunger, lack of prospects, and fear are associated with a social situation of poverty, exclusion, prejudice, and total absence of basic human rights. When examined together, these elements define different configurations in the migrants' increased vulnerability to HIV/AIDS. The groups' increased vulnerability relates to the socioeconomic complexity that must be considered in HIV/AIDS control and prevention programs. (+info)
Epidemiology of malaria in a hypoendemic Brazilian Amazon migrant population: a cohort study.
(64/715)
The present study describes aspects of the epidemiology of malaria in a migrant population living in a hypoendemic area in Brazil using an open cohort study design. Rural settlement residents in Leonislandia, Peixoto de Azevedo, Mato Grosso, Brazil were followed from September 1996 to April 1997. At baseline, an interview and malaria diagnoses were carried out and spleen size was measured. Incident cases were detected through follow-up visits and laboratory records. Cox regression was used to assess risk factors for time to malaria onset. Eighty percent (n = 414) of the study population (n = 521) contributed follow-up data. Overall, malaria prevalence during any study visit ranged from 0.3% to 5.4% and the malaria incidence rate (IR) was 4.49 (95% confidence interval = 3.66, 5.46) per 100 person-months. The IR of Plasmodium vivax malaria was approximately four times higher than the IR for P. falciparum malaria during follow-up. Among individuals who had had malaria during his or her lifetime, 14.03% reported hospitalization (median duration = 3 days) and 70.1% reported days of work lost (median duration = 4 days for P. falciparum malaria and 3 days for P. vivax malaria) related to the last malaria episode. No important risk factor was associated with the malaria IR. The fact that neither work-related factors nor age was associated with the risk of malaria indicates that indoor/peri-domiciliary transmission by the local vector is more important or as important as workplace-related transmission.
