    C H Withey, Olia Papacosta et al.ARTICLEJournal of Epidemiology and…1992Cited by: 1References: 1

    STUDY OBJECTIVE--The aim was to investigate the effect on respiratory health of male middle tar smokers changing the tar and nicotine levels of the cigarettes they smoke for a six month period. DESIGN--This was a randomised controlled trial. Middle tar smokers were randomly allocated to smoke one of three different types of cigarette (low tar, middle nicotine; middle tar, middle nicotine; and low tar, low nicotine) in place of their usual cigaret…

  • Repeatability of a questionnaire to assess respiratory symptoms in smokers

    C H Withey, C E Price et al.ARTICLEJournal of Epidemiology and…1988References: 3

    To evaluate the repeatability of a questionnaire designed to assess change in respiratory symptoms 90 smokers were interviewed on two occasions. The questionnaire included questions from the Medical Research Council questionnaire on respiratory symptoms, questions on acute chest illness and cough and phlegm production in the preceding two weeks, a modification of Field's card system for estimating frequency of cough, and an objective assessment o…

  • The Hawthorne effect in the measurement of adolescent smoking

    Michael Murray, A V Swan et al.ARTICLEJournal of Epidemiology and…1988Cited by: 2References: 2

    It is possible that the process of repeatedly measuring the smoking behaviour of adolescents may very well affect that behaviour. This paper reports a test for the extent of such a "Hawthorne" effect in a longitudinal survey of smoking by English adolescents. The self-reported smoking behaviour of 15-16 year olds who attended schools which had participated in the study for five years was compared with that of 15-16 year olds who attended other sc…

  • Relation between parents' and children's smoking behaviour and attitudes

    Michael Murray, S Kiryluk et al.ARTICLEJournal of Epidemiology and…1985Cited by: 8References: 7

    In the MRC/Derbyshire Smoking Study, a cohort of about 6000 adolescents was surveyed annually about their smoking behaviour, attitudes, and other issues from when they entered secondary school at 11-12 until 15-16 years and then again at 18-19 years. Their parents answered a similar questionnaire when their children were aged 11-12 and 15-16 years. In this paper we report the findings of an investigation focussed on the relation between parents' …

  • School characteristics and adolescent smoking. Results from the MRC/Derbyshire Smoking Study 1974-8 and from a follow up in 1981

    Michael Murray, S Kiryluk et al.ARTICLEJournal of Epidemiology and…1984Cited by: 4References: 7

    In the MRC/Derbyshire Smoking Study a cohort of about 6000 adolescents was surveyed annually from 1974 when they entered secondary school aged 11-12 years until 1978 when they reached 15-16 years. In 1981 after the adolescents had left school they were again surveyed by post. Each year from 1974 to 1978 and again in 1981 they answered a questionnaire on their smoking behaviour and other issues. Information on the schools attended by these adolesc…

  • Long term effect of a school based antismoking programme

    Michael Murray, A V Swan et al.ARTICLEJournal of Epidemiology and…1984Cited by: 2References: 2

    In the winters of 1977-8 and 1978-9 about 400 children in seven junior schools in northern England were taught the "My Body" health education programme. In the springs of 1980 and of 1982 these children, and an age matched control group, answered a questionnaire about their smoking behaviour, knowledge, and attitudes. Comparison of the two groups suggested that the programme had had a positive effect on the boys but a negligible, or even negative…

  • Respiratory illness in British schoolchildren and atmospheric smoke and sulphur dioxide 1973-7. I

    R J Melia, Ruth Melia et al.ARTICLEJournal of Epidemiology and…1981Cited by: 1References: 3

    The relation between respiratory illness and atmospheric smoke and sulphur dioxide (SO2) was investigated from 1973 to 1977 in children aged 6 to 11 from a random sample of 28 areas in England and Scotland. Cross-sectional results are presented for 1975, and results from other years briefly summarised. In 1975 there were 19 areas with data on pollution and in these areas the sample included 5787 children of white ethnic origin of whom 4116 (71%) …
