Reconstruction of Indian life tables for 1901-1981 and projections for 1981-2001.

"An attempt has been made to reconstruct life tables for India from 1901-11 to 1971-81 and to project for the decades 1981-91 and 1991-2001 by adopting a Brass relational model. The earlier actuarial life tables seem to have been based on a British model of sex differentials in mortality leading to higher life expectancies for females--not in tune with Indian experience. Consistency has been attained in this study by taking recourse to mortality patterns obtained from the Sample Registration System."

Analysis and projection of national and regional mortality for countries of the European Economic Area.

"Three scenarios of future mortality trends are presented for all countries of the European Economic Area. The high scenario assumes a considerable decline in mortality rates. Consequently life expectancy at birth will continue to increase at about the same rate as during the last decades.... In the low scenario only a small decline in death rates is assumed. This scenario assumes that there will be no convergence between countries. Moreover the current differences between male and female mortality are assumed to persist."

Preliminary experiment with computerized anamnesis in gynecology and reproductive health.

The Hospital of the Faculty of Medical Sciences of the State University of Campinas is implementing an Integrated Health Care Programme, whose objectives are early detection of risk factors of several diseases and the evaluation of the patient's reproductive health at the moment of the first visit to the Hospital. The initial results of this program encouraged us to try to apply it all to our own clientele. The present lack of material resources and qualified manpower leads us to concentrate all our attention on the patient's immediate complaints. This situation indicated to us that the only way to implement the program should be by means of a computerized questionnaire able to detect diseases and risk factors early. This paper presents the preliminary results of the application of computerized questionnaires to evaluate health risks. The authors conclude: The application of a computerized questionnaire met with very favorable reception by the clientele; In some segments of the population, the questionnaire can be answered by the patients in direct interaction with the computer; Programmes which evaluate risk factors need to be carefully revised before being put to use; The system operates on a relatively low cost basis, which could bring undeniable benefits to primary health care.

Tobacco and occupation as risk factors in bladder cancer: a case-control study in southern Belgium.

A pilot case-control study on bladder cancer, with population-based controls matched for each of 74 cases, has been conducted in two industrial areas of Southern Belgium in order to analyze the influence of tobacco use and occupation. Observed bladder cancer risk for smokers is more than 5 times higher than that for non-smokers, and the risk for people having an a priori hazardous occupation is about 3.5 times higher than that of other subjects. A dose-response relationship was found for tobacco exposure and duration of employment. It seems that the risk is increased in a log-linear way by these variables. Population attributable risks show that in 20 cases of bladder cancer, 17 could be explained by the two factors combined. This study also reveals an increased risk for metal workers, truck and engine drivers, coal-miners, and rubber and coal-tar workers. The risk for metal workers is specially high in the case of turners, metal fitters, blacksmiths, stokers and workers exposed to hot metal.

A statistical approach to monitor ongoing intervention for control of lymphatic filariasis.

Lymphatic filariasis is a major public health problem, affecting 120 million people in 73 countries. One-third of the infected people infected with lymphatic filariasis live in India. Newer tools and control strategies have encouraged the hope of its elimination. One of the components in the elimination strategy is treating the entire population with a single dose of DEC annually to reduce microfilaraemia load. In India, the programme of drug distribution on a community-wide basis was taken up in 1997 on pliot scale in 13 districts within the existing public health system network. In developing epidemiologic approach to monitor and evaluate the success of ongoing intervention the utility of Lot Quality Assurance Sampling techniques for corrective measures by the programme managers is presented and discussed in this paper.

Coeliac disease in the year 2000: exploring the iceberg.

It is now generally believed that subclinical coeliac disease is common in the general population. We have undertaken screening for this disorder in a school district in central Italy. Screening was divided into three levels: first, IgG and IgA antigliadin antibody (AGA) assay on capillary blood obtained by finger prick; second, AGA plus IgA anti-endomysium antibody (AEA) test and measurement of serum immunoglobulins in venous blood; and third, intestinal biopsy. 3351 students (66% of the eligible population) aged 11-15 years attended first-level screening. 71 (2%) were recalled because of AGA positivity; 18 of these satisfied second-level criteria and underwent intestinal biopsy. Coeliac disease was diagnosed in 11 subjects, most of whom had no serious symptoms. Selective IgA deficiency was found in 4 subjects, 1 of whom also had coeliac disease. The prevalence of subclinical coeliac disease in the study group was 3.28 per 1000. Coeliac disease screening is feasible and involves only slight discomfort to the general population. Such screening can detect large numbers of cases of coeliac disease, which can be treated with a gluten-free diet. Many subclinical cases of coeliac disease would not be detected by screening only a selected group of at-risk patients.

Using the premarital examination for population-based surveillance for HIV in China: a pilot study.

All couples attending the premarital examination at four selected sites in Zhejiang and Yunnan provinces in China were included in this study. Blood from 9952 individuals was tested for HIV-1 using a gelatin particle agglutination technique. There were no HIV-positive individuals in Zhejiang. In Yunnan, 28 of 3742 individuals were positive, a prevalence of 0.75%. The premarital examination should be used for voluntary counselling and testing and anonymous surveillance for HIV in high prevalence areas.

[From minimal household units to household projections: an application to Canadian data].

"The headship rate method for household projections has been criticised for its silence concerning household composition, while alternative models have yet to resolve how to estimate households from the distribution of individuals by household status projected by their models. By combining an indicator of household composition with an indicator of headship, the method proposed here attempts to remedy these problems. The application to Canadian households could be viewed as an adaptation of the headship rate method, but would ideally serve as the second step of a model more representative of the household formation process."

Potential labor force supply and replacement in Mexico and the states of the Mexican Cession and Texas: 1980-2000.

"The purpose of this article is to carry forward the examination of potential labor force supply and replacement of men in Mexico into the 1980-1990 and 1990-2000 decades so that the possible future course of international migration between that country and the United States may be better anticipated. In addition, to provide a degree of developmental perspective, trends in potential labor force supply and replacement in Mexico since 1930-40 are presented." As a contrast, "ratios of potential labor force supply and replacement in the southwestern United States--the states of the Mexican Cession and Texas, which were formerly part of Mexico--also are shown for the 1980-1990 and 1990-2000 intervals." The results suggest that "in Mexico, the projected number of males entering the labor force ages will be about 48 percent larger in the 1980s than in the 1970s.... Fertility declined significantly in Mexico in the 1970s, and therefore the number of new entrants to the labor force ages in the 1990s will decline...." The implications for international migration between Mexico and the United States are considered.

[Life-style and demographic behavior: an application of latent class analysis].

"The aim of this study is to construct a lifestyle typology which is relevant for demographic behaviour. The concept lifestyle is defined as attitudes towards marriage, family, parenthood and the labour force participation of women. The lifestyle indicators available in the 1988 Netherlands Fertility Survey are used to construct a typology by means of latent-class-models.... The lifestyle typology can be used in two ways for projection purposes. Firstly, it can be as an explanatory variable in models for demographic behaviour. This application is demonstrated with a discrete-time hazard model for first births....Secondly, it can be used to identify innovators with respect to demographic behaviour and to quantify alternative hypotheses about the number of followers. This is demonstrated by calculating the future proportion of childlessness." (SUMMARY IN ENG)

Exposure to toxic waste sites: an investigative approach.

Improper dumping and storage of hazardous substances and whether these practices produce significant human exposure and health effects are growing concerns. A sequential approach has been used by the Centers for Disease Control and the Agency for Toxic Substances and Disease Registry in investigating potential exposure to and health effects resulting from environmental contamination with materials such as heavy metals, volatile organic compounds, and pesticide residues at sites throughout the United States. The strategy consists of four phases: site evaluation, pilot studies of exposure or health effects, analytic epidemiology studies, and public health surveillance. This approach offers a logical, phased strategy to use limited personnel and financial resources of local, State, national, or global health agency jurisdictions optimally in evaluating populations potentially exposed to hazardous materials in waste sites. Primarily, this approach is most helpful in identifying sites for etiologic studies and providing investigative leads to direct and focus these studies. The results of such studies provide information needed for making risk-management decisions to mitigate or eliminate human exposures and for developing interventions to prevent or minimize health problems resulting from exposures that already have occurred.

Linking the global positioning system (GPS) to a personal digital assistant (PDA) to support tuberculosis control in South Africa: a pilot study.

BACKGROUND: Tuberculosis (TB) is the leading clinical manifestation of HIV infection and caseloads continue to increase in high HIV prevalence settings. TB treatment is prolonged and treatment interruption has serious individual and public health consequences. We assessed the feasibility of using a handheld computing device programmed with customised software and linked to a GPS receiver, to assist TB control programmes to trace patients who interrupt treatment in areas without useful street maps. In this proof of concept study, we compared the time taken to re-find a home comparing given residential addresses with a customised personalised digital assistant linked to a global positioning system (PDA/GPS) device. Additionally, we assessed the feasibility of using aerial photographs to locate homes. RESULTS: The study took place in two communities in Greater Johannesburg, South Africa: Wheillers Farm, a relatively sparsely populated informal settlement, and a portion of Alexandra, an urban township with densely populated informal settlements. Ten participants in each community were asked to locate their homes on aerial photographs. Nine from Wheillers Farm and six from Alexandra were able to identify their homes. The total time taken by a research assistant, unfamiliar with the area, to locate 10 homes in each community using the given addresses was compared with the total time taken by a community volunteer with half an hour of training to locate the same homes using the device. Time taken to locate the ten households was reduced by 20% and 50% in each community respectively using the PDA/GPS device. CONCLUSION: In this pilot study we show that it is feasible to use a simple PDA/GPS device to locate the homes of patients. We found that in densely populated informal settlements, GPS technology is more accurate than aerial photos in identifying homes and more efficient than addresses provided by participants. Research assessing issues of, confidentiality and cost effectiveness would have to be undertaken before implementing PDA/GPS - based technology for this application. However, this PDA/GPS device could be used to reduce part of the burden on TB control programs.

Chinese herbal medicines used in pregnancy: a population-based survey in Taiwan.

PURPOSE: To explore the use (prevalence and related factors) of Chinese herbal medicines used by pregnant women. METHODS: We used multistage stratified systematic sampling to recruit 2048 postpartum women from the Taiwan national birth register between November and December 2003. Subjects underwent a home interview 6 months after their deliveries. A structured questionnaire was successfully applied to 87% of the sampled population. RESULTS: At least one Chinese herbal medicine was used during pregnancy by 24.1% of the interviewed subjects. Pregnant women with threatened abortion appeared to use more Chinese herbal medicines than other pregnant women. CONCLUSION: Chinese herbal medicines are frequently used by pregnant women in Taiwan and are very frequently used by those with a threatened abortion.

The global epidemiology of the HIV/AIDS pandemic and its projected demographic impact in Africa.

The global epidemiology of HIV/AIDS has evolved to the point that the pandemic now predominantly affects heterosexuals, especially in developing countries. This article summarizes the status of the HIV/AIDS pandemic as of the early 1990s; provides estimates and short-term projections of AIDS mortality in a hypothetical country of sub-Saharan Africa; projects the potential demographic impact of AIDS in a hypothetical sub-Saharan country; and describes the major problems associated with modelling the long-term demographic impact of this pandemic. Estimated AIDS cases and deaths up to 1992 were extrapolated from public health surveillance data and through use of the WHO model. Estimates of HIV seroprevalence were based on available HIV serological data. For developed countries, HIV estimates developed by national experts and/or national AIDS programmes were used, and for developing countries estimates by regional experts were used or were prepared by WHO. For the first half of the 1990s, projections of AIDS cases and deaths were derived from the WHO model; beyond the mid-1990s, the potential effects of AIDS on selected demographic indicators were derived from a demographic projection model developed by the World Bank. Although estimates and long-term projections cannot be made with great precision, the general dimensions of the HIV/AIDS pandemic have been more clearly delineated now at the start of its second decade. Epidemiological data indicate that in industrialized countries, where extensive spread of HIV began in the late 1970s or early 1980s, the majority of HIV infections occurred during the first half of the 1980s.(ABSTRACT TRUNCATED AT 250 WORDS)

Emergency medical services during the siege of Sarajevo, Bosnia and Herzegovina: a preliminary report.

BACKGROUND: The siege of Sarajevo is a long-term, human-made, medical disaster of international significance. The delivery of emergency health care provided to the large civilian population held captive in that war zone for an extended time was studied. METHODS: In May 1993, a humanitarian and fact-finding visit to Sarajevo was conducted. Physicians, administrators, and public health officials were interviewed; epidemiological data were acquired--the resuscitation of war casualties at the two largest hospitals were observed; and local published reports and videotaped footage on the organization and delivery of prehospital and hospital care were reviewed. The videotapes also served to document war crimes. RESULTS: Daily bombardment and sniper fire directed at civilians have caused a steady stream of casualties (64,130, or an average of 119 killed or injured per day in 18 months). Eighty percent of the victims were civilian. Despite hazardous conditions from direct shelling, disruption of vital lifelines, and shortage of supplies, medicines, oxygen, and anesthetics, the physicians continue to provide at least a minimum standard of resuscitative care. Seventy percent of all war victims were transported to hospitals in private vehicles. Most casualties (93%) received some form of prehospital, basic first-aid from lay bystanders or first responders. From November 1992 to February 1993, 27,733 patients were treated in hospitals, resulting in 2,139 major surgical procedures. The primary cause of death in 71 of 273 victims was prolonged hemorrhagic, hypovolemic shock. Sixty-one percent of these victims died within 24 hours of injury. CONCLUSIONS: Continuous needs assessment of a civilian population in a war zone should be accompanied by rapid delivery of outside aid. International "peacekeeping" forces should protect hospitals and their staffs, and ensure the entry of supplies and evacuation of some patients. A public trained in life-supporting first-aid, and physicians and paramedics with experience in advanced life support may have enhanced lifesaving efforts in Sarajevo.

Trade and migration: the case of NAFTA.

"This article provides background information on NAFTA [the North American Free Trade Agreement], reviews data on its economic effects, and summarizes studies and projections of NAFTA's likely effects on Mexico-to-U.S. migration. Migration factors (demand-pull, supply-push, and networks) are examined to determine whether NAFTA's effect on economic development particularly in the border areas will accelerate or retard migration. The conclusion is that NAFTA is likely to produce a temporary migration hump, slightly raising already high migration levels in the 1990s, but reducing the volume of Mexico-to-U.S. migration that would otherwise occur over subsequent decades."

Trends in lifestyle 1986-99 in a 25- to 64-year-old population of the Northern Sweden MONICA project.

AIMS: The authors explore the time trends in lifestyle factors in the Northern Sweden MONICA population, including physical activity, intake of certain foods, coffee and alcohol consumption, smoking, and the use of smokeless tobacco. METHODS: Four health surveys during a 14-year time span were compared (1986, 1990, 1994, and 1999). The participation rate in all surveys was high. A questionnaire with similar or comparable questions about lifestyle factors was used across all health surveys. RESULTS: A large variation was demonstrated in the consumption of saturated fat in dairy products across the surveys. The use of butter on bread and of 3% fat milk clearly declined in favour of using low-fat margarine and 1-1.5% fat milk. A decline in the intake of boiled or baked potatoes together with an increase in the intake of pasta and rice was demonstrated. There were no changes in leisure-time physical activity. The proportion of the population using tobacco was unaltered. In men, smoking declined during the period but simultaneously there was an increase in the use of smokeless tobacco. The use of "boiled" or Scandinavian coffee diminished and more frequent use of alcohol was seen, especially in men. CONCLUSION: Pronounced changes were seen in food consumption with a decrease in saturated fat intake, boiled coffee, and potatoes and an increase in alcohol, rice, and pasta consumption. No clear time trends were found in physical activity or in the use of tobacco.
