NOISE EXPOSURE AS A DETERMINANT OF ISCHAEMIC HEART DISEASE.

Objective

TO ASSESS THE LONG TERM EFFECTS OF DAILY NOISE EXPOSURES ON THE MORBIDITY FROM ISCHAEMIC HEART DISEASES IN POPULATIONS OF MALES AROUND CARDIFF (WALES).

IN 1981, THE M R C INITIATED A LONGITUDINAL EPIDEMIOLOGICAL SURVEY TO ENQUIRE UPON THE DIFFERENCES IN THE CONCURRENCE OF ISCHAEMIC HEART DISEASE (IHD) IN WELSCH POPULATIONS OF MALES, ABOVE 45 YEARS, LIVING CLOSE TO CARDIFF.
TWO GROUP OF ABOUT 2,500 MALES EACH, ONE AROUND CAERPHILLY IN WHICH THE OCCURENCE OF IHD WAS KNOW TO BE HIGH, AND ANOTHER ONE WITH NORMAL IHD OCCURENCE, PASSED DETAILED MEDICAL EXAMINATIONS AND THEU WERE CHECKED FOR MANY FACTORS SUCH AS DIET, DRINKING AN SMOKING HABITS, LIVING CONDITIONS, EMPLOYMENT, SOCIAL CLASSES.
ALSO NOISE LEVELS IN THE SURROUNDINGS OF HOUSES AND DWELLINGS WERE RECORDED TO DETERMINE THE NOISES EXPOSURES OF THESE POPULATIONS.

CORRELATIONS BETWEEN NOISE LEVELS IN THE ENVIRONMENT AND SYSTOLIC BLOOD PRESSURE OR BLOOD CHOLESTEROL CONCENTRATIONS WERE OBSERVED.
FOR THE NEXT FOUR YEARS, THE EPIDEMIOLOGICAL SURVEY CONTINUES FOR COMPLETING THE INDIVIDUAL NOISE EXPOSURES DURING DAY, EVENING AND NIGHT TIME, FOR PERFORMING OTHER MEDICAL AND BIOLOGICAL EXAMINATIONS FOR RECORDING THE OCCURANCE OF IHD IN ORDER TO DETERMINE HOW THE NOISE DOSE INTERACTS WITH OTHER FACTORS ON THE MORBIDITY DUE TO ISCHAEMIC HEART DISEASES.
