Higher blood pressure in adults with less education. Some explanations from INTERSALT.

An inverse association between social class and disease has frequently been reported; education, an indicator of social class, was negatively related to blood pressure in several studies. Reasons are not clear. INTERSALT, an international study on electrolytes and blood pressure, obtained data on years of education for 10,079 adults in 52 centers in 32 countries. Data presented here are for 47 centers, omitting five where the population in the sample had no education or no differences in educational level. Regression coefficients were calculated for the education-blood pressure association in each center. An inverse association was found for men in 28 centers and for women in 38. Center coefficients were combined to give a studywide estimate of that association. When adjusted only for age, systolic pressure in men was 1.3 mm Hg higher for 10 fewer years of education (p less than 0.05) and for women 4.5 mm Hg higher (p less than 0.001). However, when adjusted also for five lifestyle factors (24-hour sodium and potassium excretion, body mass index, alcohol intake, and smoking), these estimates were reduced by about one half, and the inverse association was no longer significant for men. Similar findings were obtained for diastolic pressure. Those with less education had on average higher sodium excretion, lower potassium excretion, greater body mass, and higher alcohol intake, all factors tending to increase blood pressure. Improvement of these factors, which help explain the differences in blood pressure related to years of education, has the potential to reduce the blood pressure disadvantage associated with lower socioeconomic status.

[Acute accidental poisoning with hospital disinfectant. 45 cases of which 13 with fatal outcome].

Airsane HP 800 is a disinfectant widely used in hospitals as a powder to be diluted in water. It mainly contains a mixture of quaternary ammonium compounds. Forty five cases of acute accidental poisoning with this product have been reported to the Paris Poison Centre. All the victims were mentally disturbed patients: 2 were young adults hospitalized in psychiatric units and the other 43 were old people hospitalized for senile dementia. All ingested the solid preparation which was left in their room by hospital workers who did not know it was dangerous. Corrosive burns of the mouth, pharynx, oesophagus and sometimes of the respiratory tract were produced in most patients. Thirteen of them died. All were old persons. Ten had inhalation pneumonitis and died of acute respiratory distress one hour to twelve days after taking the powder. Progressive deterioration was responsible for the death of the other three between the 19th and 40th days. These severe accidental poisonings could easily be prevented by a better information of hospital workers, and by storing the disinfectant and preparing the solution beyond the reach of patients.

Recruitment methods and differences in early, late and non-respondents in the first MONICA-Catalonia population survey.

The early response rate in the first MONICA-Catalonia population survey was 52.7% and the final response rate was 73.8%. The intensity of recruitment effort in this survey led to a considerable increase in response rate (20%), with the extra cost per late respondent being relatively low ($13.9). Added recruitment effort was most effective in the youngest age group, 25-34 years. It was also more effective among women living in urban areas than among those from rural areas. In men, early respondents had a higher proportion of smokers than late respondents, and in women, early respondents had higher systolic and diastolic blood pressure levels and were more aware of their history of high blood pressure than late respondents. Non-respondents were less educated than respondents in both sexes, and this was more marked in women. No differences were found in the proportion of smokers between respondents and non-respondents. Respondents were more aware of their high blood pressure history than non-respondents. The recruitment costs and distribution of non-response components are given.

Coronary heart disease mortality trends and related factors in Spain.

Coronary heart disease (CHD) mortality rate in Spain is relatively low, but showed an annual increase of 6.2% for men and of 4.2% for women between 1968 and 1977. There are marked differences in CHD mortality rate between regions. Although there is little data available on the prevalence and trends of CHD risk factors, these data seem to suggest a relatively high level of the main risk factors and a tendency toward adverse development. Socioeconomic and sociocultural changes due to a fast industrial development followed by an economic crisis with high rates of unemployment may produce an unpredictable change in CHD trends in the next years.

Spirometric reference values from a Mediterranean population.

Maximal expiratory flow-volume (MEFV) curves were measured in 1044 healthy nonsmoking volunteers living in the Barcelona area, as part of a larger interhospital project to obtain reference values of pulmonary function tests. Forced vital capacity (FVC), one-second forced expiratory volume (FEV1), FEV1/FVC, %, forced maximal mid-expiratory flow (FEF25-75%), peak expiratory flow rate (PEF) and maximal expiratory flow at 50 and 75% of FVC (MEF50% and MEF25% respectively) were obtained and expressed at BTPS conditions. Techniques and equipments followed both the recommendations of the American Thoracic Society (ATS) and of the European Community for Coal and Steel (ECCS). Prediction equations for age 20 through 70 were calculated for both sexes from a final sample composed of 870 adult subjects, 443 males and 427 females. Simple linear equations using height, age and body weight predicted all spirometric variables as well as more complex equations except MEF25%. Logarithmic equations were proposed for MEF25% to correct for the heteroscedasticity shown in a simple linear model. To our knowledge, this study provides reliable spirometric equations from a large urban Mediterranean sample which were lacking so far in the literature.
