[Effect of parents on the tobacco use of their children].

A survey carried out in autumn 1978 in a Paris state secondary school (2266 pupils) enabled us to study the precocity and prevalence of smoking habits in boys and girls aged 14.9 years on average, according to their parents' smoking habits and attitudes. The proportions of smokers were 21.8% in boys and 31.2% in girls. These proportions were lower if parents forbade smoking and higher if they allowed it, or simply advised their children against it. The proportion of smokers and precocity of smoking increased with parents' smoking habits. This result was confirmed by a stepping-up discriminant analysis. We also found that the influence of peers entailed a greater precocity in smoking and that those who smoked to assume a countenance smoked a greater number of cigarettes.

[Resistance of the Koch bacillus to antibacillary agents in the Department of the Lower Rhine].

The aim of this work was to study drug resistance of M. tuberculosis to Streptomycin (SM), Isoniazid (INH), Ethambutol (EMB) and Rifampicin (RMP) in the department of the Bas-Rhin from 1971 to 1978. On 2,995 original culture plates which were positive, 1,561 antibiograms were performed at the C.E.R.P. The proportion of those tested has increased over the years from 27.8% in 1971 to 80.6% in 1978 because of the increasing number of laboratories participating in the study. The research is based on 1,511 cultures of M. tuberculosis and the population was split into two groups: 1,386 untreated subjects or treated for less than 15 days (primary resistance) and 125 subjects who had already been treated (acquired resistance). Over all the years, primary resistance to at least one drug was 6.9%. Primary resistance to SM was 3.0%, to INH 2.2% and to both 1.4% (the levels of primary resistance to EMB and RMP were practically nil). Acquired resistance to at least one of these antibiotics was 16.0% with the same order as for primary resistance: resistance to SM alone = 7.2%, to INH alone 4.0% and both together 2.4%. The proportions were greater than for primary resistance but concerned fewer subjects as only 8% of the population had been previously treated. There were no cases of primary or acquired resistance to Rifampicin alone.

Prevalence of respiratory symptoms in Parisian teenagers according to smoking habits.

The relationship between respiratory symptoms and smoking habits, according to sex, was studied in 2266 teenagers attending secondary school in Paris. Among smokers, the prevalence of usual cough or phlegm, or both, was higher in girls than in boys, whereas such was not the case among non-smokers. That prevalence, as well as the proportion of people with wheezing, were more closely associated with the total number of cigarettes ever smoked by girls than by boys. Moreover, there was a weak but significant association between the total number of cigarettes smoked and respiratory function--FEV1/Ht3 in girls only.

[The results of educational anti-smoking measures at the primary school level (author's transl)].

A retrospective study was made from a self-administered questionnaire distributed to 4,166 pupils aged 15 to 18, attending "Bas-Rhin" high schools, in Spring, 1979. The results demonstrate the relative effectiveness of educational anti-smoking measures when information is given to specific age groups. Information given at the primary school level results in a proportionately and significantly lower number of smokers; there was also a tendency both to smoke fewer cigarettes per day, and to choose brands having lower tar and nicotine levels. These pupils also left a greater portion of the cigarette unsmoked, i.e. they left longer cigarette butts. In addition, the number of pupils who had never smoked was greater in those groups who received information at the primary school level; and the number of ex-smokers (those who had given up smoking for at least one year) was also greater. The results emphasize the effectiveness and importance of public health measures carried out in young children.

[Factors related to a population's behaviour towards x-ray screening of tuberculosis (author's transl)].

A study on the behaviour of a population towards a preventive measure (X-ray screening of tuberculosis) was carried out in 6,176 adults (average age 55), offered screening by the Mobile X-ray Screening Department of "D.D.A.S.S.", from February to June 1979, 68.6 per cent of them completed and returned the self-administered postal questionnaire. The following factors were related to people's behaviour: age, occupation, educational level, the fact of being invited for the second or third time and of not being vaccinated by B.C.G. According to the results of this survey no personal motivation related to the knowledge and the fear of the disease seems to guide people in their response to the measure offered.

Smoking in teenagers: some psychological aspects.

A large survey was carried out by means of a self-administered questionnaire to the 30,000 teenagers attending school in a French "département" (Bas-Rhin) during spring 1976. This survey revealed some psychological factors about smoking in teenagers as they relate to school and family environment; 30.3% of the subjects were smokers. This proportion was higher in boys than in girls, and increased with age. Statistical analysis showed a greater number of smokers in non-mixed schools, in schools where adults were admitted or where regulations did not forbid smoking, as well as among boarders. We also found a greater number of smokers when the family smoked, when the parents lived outside the "départment" or belonged to the lower social classes.

Asbestos risk among full-time workers in an electricity-generating power station.

A matched survey of 55 full-time workers probably exposed to asbestos in an electricity-generating power station (exposed group) and of 53 unexposed workers in an automobile plant has been conducted. The asbestos risk in the power station was confirmed by the presence of airborne fibers in the range 0.1--6000 X 10(-9) g/m3 in the air sampled during the survey period and by the presence of FB in the sputa of 32.7% of the workers. The following parameters were significantly related to asbestos exposure in the study group: FB in the sputa, localized rectitude of the diaphragm, pleural thickening, pleural calcification, and the chest pain. Moreover, for all persons studied, gastrointestinal symptoms and recent hoarsening of the voice were significantly related to the number of FB in the sputa.

[A self-administered questionnaire applied to 30,000 teen-agers. Assessment of this method of data collection (author's transl)].

In the French "département" of "Bas-Rhin", about 30,000 teen-agers filled in a self-administered questionnaire about respiratory symptoms, in spring 1976. The assessment of this method of data collection shows a very high response rate (99,7 p. cent). If we consider as incomplete all the questionnaires having at least one unanswered question concerning respiratory symptoms or smoking, 55,8 p. cent of them were incomplete, but for most questions non-response rate was lower than 4 p. cent. The consistency of answers was very satisfactory (mean inconsistency rate: 0,39 p. cent) and the likelihood of answers was proved.

[Respiratory symptoms in school-age children, in 7 areas of France].

A study of respiratory symptoms in 6918 schoolchildren aged 6-10 years was carried out in 1975, in 7 French areas having different pollution levels. The proportion of children with respiratory symptoms (cough and/or wheezing), dyspnoea, colds and colds "going to the chest" was higher in Paris than in the other areas. The frequency was related to age, allergy and some socio-economic factors. After adjustment for these factors the difference in the respiratory symptoms between those in Paris and elsewhere was still statistically significant. According to 1974 average pollution data, air was more polluted in Paris than in the other areas, particularly for black smoke.

Silica exposure and chronic airflow limitation in pottery workers.

We assessed the relationship between exposure to silica dust and chronic airflow limitation in an epidemiological survey conducted among pottery workers and controls who were of the same socioeconomic status (average age: 35 y; 78% males). Data were collected by questionnaire for respiratory symptoms, allergy, respiratory history, smoking habits, and occupation. Lung function was measured with a computer-equipped Gauthier spirometer. We excluded subjects with silicosis or doubtful chest x-ray, and two exposure levels were defined. No differences were observed between exposed subjects and controls with respect to respiratory conditions. Mean pulmonary function values for men and women were significantly lower, after adjustment for age, height, and smoking habits, in even indirectly exposed pottery workers, compared with controls. These results suggest that exposure to silica dust is a risk factor for chronic airflow limitation and is independent of radiographic changes.

[Can an improvement in pulmonary function be demonstrated in children under 10 years sent to winter sport classes?].

The purpose of this research was to appreciate the benefit of a Winter sport class for young children. The study was carried out, in the Northern suburb of Paris, among girls and boys, aged 8.4 on average. Among them, 91 went to the mountains and 65 (controls) stayed in town. A spirometry and a flow-volume curve were measured: before starting, on coming back home and 2 years later. The parents filled in questionnaires about children's respiratory symptoms and history. Morphometric data were recorded. Reference values of this population were obtained by taking height into account. No difference in respiratory symptoms and history was observed between the groups at the beginning of the survey. However, the children who went to the mountains had lower age, weight and height than the others. Nevertheless, 2 years later, these children had a more important increase of F.E.F.1 and F.E.F.25-75. They had also a more important increase of their flows.

[Evaluation of the frequency of asthma among the adolescents attending school in the Bas-Rhin (author's transl)].

The frequency of asthma in a population including all the adolescents attending school in the department of Bas-Rhin (29 138) in May and June 1976, is 4,1%. This rate is 4,9% in boys and 3,4% in girls. The frequency of asthma is higher in urban areas (5,0%) than in rural areas (3,8%). Asthma is related to respiratory symptoms and is related to more school absenteeism (26%) than in non asthmatics (13,7%). These findings are confirmed by the data given in other medical surveys.

[Chronic cough in schoolchildren from the Bordeaux area. Results on 15000 adolescents].

A large epidemiological survey carried out in the spring of 1981 among the teenagers attending school in Bordeaux and its surroundings enabled us to study the relationship between the history of broncho-pulmonary diseases in childhood and infancy and chronic cough in teenagers. The population consisted of 15,247 pupils (average age, 16.5 years). There were 47% boys. Data collection was carried out by means of self-administered questionnaires filled out in class. Besides socio-demographic information and questions about smoking habits, the pupils answered questions concerning present respiratory symptoms and history of bronchopulmonary diseases before 2 years of age and between ages 2 and 6. A chronic cough was present in 4.3% of the pupils. This proportion was significantly higher in girls, older pupils, smokers, those belonging to lower social classes and asthmatics. The relationships between history of bronchopulmonary diseases during childhood and infancy and present chronic cough were highly significant and remained so after adjustments for confounding factors. This relationship existed also in the sub-population of non-asthmatic pupils.
