The main health effects can be classified as either physical (trauma, respiratory diseases, etc.) or psychological (depression, anxiety, nightmares, neurosis, etc.). Popocatépetl, the most famous active volcano in Mexico, lies on the borders of the States of Mexico, Puebla and Morelos. In 1993, seismic activity intensified, as did as the emission of fumaroles, followed in December 1994 by moderate tremors and strong emissions of gases and ash. In 1996, a number of seismic events led to an unexpected explosion. A daily emission of 8,000 to 15,000 tonnes of sulfur dioxide has been measured. Popocatépetl is located in a densely populated region of Mexico. A complex network to monitor the volcano using sophisticated equipment has been set up, including visual surveillance, seismic, geochemical and geodesic monitoring. An early warning system (SINAPROC/CENAPRED) has been developed to keep the population permanently informed. The warning system uses colour codes: green for normal, yellow for alert, and red for warning and evacuation. An emergency plan has been prepared, including evacuation and preparation for medical centres and hospitals in the region, as well as intense public information campaigns.</p>","PeriodicalId":76824,"journal":{"name":"World health statistics quarterly.

Our results eliminate the hypothesis that inhalation intake of radioactive aerosols was a considerable pathway of exposure for staff at the Chernobyl nuclear power plant. It would conceivably lead to a nonuniform dose distribution in the body. Under that condition, actual equivalent doses in some organs, e.g., in lungs and in the wall of the lower large intestine are much higher than the actual effective dose. Therefore it is impossible to correctly assess the health risk for certain cohorts of the Chernobyl accident witnesses if the inhalation pathway is neglected. In that case not only the actual effective dose, but the actual equivalent doses too play a role in radiological measurement, when evaluating the hazard for less-exposed accident witnesses. That conclusion is of great importance to radiation protection policy, the planning of epidemiological studies and the carrying out of medical remedial actions for the different cohorts of accident witnesses. The findings should be taken into consideration in planning protective measures and in assessing health effects following the Chernobyl accident.</p>","PeriodicalId":76824,"journal":{"name":"World health statistics quarterly.

Mortality in this cohort has been under study since 1950. Deaths are routinely identified through the family registry system and ascertainment is virtually complete. Cancer incidence data for the LSS cohort are also available from the Hiroshima and Nagasaki population-based tumour registry established in 1958. The central finding of the LSS is an increase in cancer risk. Besides the well-known increase in leukaemia, increases in solid cancer such as cancers of the lung, breast, stomach and thyroid have also been demonstrated. Radiation-induced leukaemia occurred 2 to 3 years after exposure, reached its peak within 6 to 8 years after the bombing, and has since declined steadily. However, this has not been true of solid cancer. Radiation-induced solid cancer begins to appear at later ages than such cancer is normally prone to develop, and continues to increase proportionally with the increase in mortality or incidence in the control group as it ages. Survivors who were exposed in the first or second decade of life have just entered the cancer-prone age and have so far exhibited a high relative risk in association with radiation dose. Whether the elevated risk will continue or will fail with time is not yet clear. It is important to continue long-term follow-up of this cohort to document the changes with time since exposure. Beyond cancer risk, increased risk of non-cancer mortality is also suggested, although it is not conclusive.</p>","PeriodicalId":76824,"journal":{"name":"World health statistics quarterly.

{"title":"An epidemiological perspective on environmental health indicators.","authors":"H Pastides","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>There is a great amount of ongoing discussion about the need to develop new ways to assess and monitor a population's disease susceptibility to environmental factors. The ultimate goal in developing these tools, called environmental health indicators, is to increase the public health community's capacity for implementing interventions to prevent disease. Much of the discussion focuses on the requirement that the indicators be relatively easy and quick to apply. However, in the rush to find useful existing indicators, or to develop new ones, there is the danger that certain other important attributes of the indicator may be overlooked. These include: (a) whether the indicator truly represents an underlying causal relationship between an environmental exposure and a health consequence; and (b) whether the proposed indicator is a reasonably valid estimate of the underlying causal factor. This article provides a framework for relating environmental health indicators to the methods of epidemiology including some guidance for selecting and evaluating the appropriateness of proposed environmental health indicators. Examples are given which demonstrate how environmental health indicators can lead to a biased interpretation of underlying associations between environmental factors and the potential for disease when they are improperly conceived. These problems can be avoided by employing routine epidemiological concepts and methods as indicators are developed and evaluated.</p>","PeriodicalId":76824,"journal":{"name":"World health statistics quarterly.

Almost three quarters of all maternal deaths were directly related to obstetrical complications during pregnancy or childbirth. Many of these deaths could probably have been avoided, if appropriate obstetric care had been available. The level of attention to problems related to maternity and childbirth needs to be raised at all responsible levels of the health service system. This must start at the health facility where attending nurses and midwives should be oriented towards pregnancy-related problems and early detection of high-risk women, with appropriate supervisory support.

A decision was taken in 1988 to start a project of pilot interventions in the organization of maternal health services and access for obstetric emergencies. A control and pilot area were chosen in order to test the validity of the interventions. The reduction in maternal mortality from the main complications (postpartum haemorrhage and eclampsia) was impressive and no more maternal deaths were registered in the pilot area with reference to these causes. The overall maternal mortality ratio per 100,000 live births dropped by more than 75% in the pilot area throughout the three-year implementation period. It was therefore shown that the synergistic effect of additional training of medical workers and traditional birth attendants, improved health education, the provision of easier access to emergency care services, the establishment of obstetric rescue teams at the county level, generally improved MCH services, and strengthened management capacity for high risk pregnancies were the most appropriate interventions to lower maternal mortality.</p>","PeriodicalId":76824,"journal":{"name":"World health statistics quarterly.
