- Abstract
Objectives: To compare long term outcomes of a randomised controlled trial of anti-smoking education in pregnancy and to examine the same outcomes according to maternal pregnancy smoking behaviour., Design: Follow up of the population included in the randomised controlled trial nine years later and of ex-smokers and non-smokers within the same hospital population., Setting: A maternity hospital in Birmingham with follow up of children in schools and mothers at home., Population: 1218 smokers recruited to the trial; also 191 ex-smokers at booking and 414 non-smokers throughout pregnancy., Methods: Children were assessed individually by psychologists in schools, and mothers interviewed at home to obtain additional information relevant to cognitive development and growth. Information on smoking during pregnancy was obtained from mothers and obstetric data from computerised case-notes, both recorded immediately following delivery., Main Outcome Measures: Height, weight, IQ and neurological soft signs at 9.4 years., Results: Differences in birthweight and length between the intervention and control groups were confirmed but no intervention-control differences were found at age 9.4 for weight, height, IQ or neurological soft signs. Differences were found for height and IQ according to mothers pregnancy smoking behaviour, but smoking did not remain an independent predictor after taking account of confounding factors. Alternative classifications of smoking behaviour, taking account of the gestation at stopping and mean cigarette consumption throughout pregnancy likewise showed no effect., Conclusions: The well established early hazards of smoking during pregnancy seem to be resolved by later childhood, with no evidence of direct long term effects on growth or cognitive functioning.

- Abstract
Parental smoking data have been abstracted from the interview records of the case-control study that first indicated that pregnancy radiographs are a cause of childhood cancer (Oxford Survey of Childhood Cancers, deaths from 1953 to 1955). Reported smoking habits for the parents of 1549 children who died from cancer were compared with similar information for the parents of 1549 healthy controls (matched pairs analysis). There was a statistically significant positive trend between paternal daily consumption of tobacco and the risk of childhood cancer (P< 0.001). This association could not be explained by maternal smoking, social class, paternal or maternal age at the birth of the survey child, sibship position or obstetric radiography. About 15% of all childhood cancers in this series could be attributable to paternal smoking.

- Abstract
Reported consumptions of alcohol and tobacco for the parents of 1641 children who died with cancer in England and Wales during the period 1977 to 1981 were compared with similar information for the parents of 1641 control subjects. Consumption of alcohol by fathers was not associated with an increased risk of childhood cancer (relative risk (RR)) = 1.05; 95% confidence interval (CI): 0.86 to 1.28), but for daily consumption of cigarettes was not shown to be associated with an increased risk and consumption of alcohol was associated with a relatively low cancer risk (RR = 0.82; 95% CI: 0.70 to 0.96). Relations between maternal consumption of cigarettes and birth weights suggested that the smoking data were equally reliable for case patients and control subjects.

- Abstract
Objective: To quantify the risks of urothelial cancer associated with smoking cigarettes., Subjects and Methods: Histories were taken from 989 patients diagnosed with urothelial cancer, 2059 electoral register controls and 1599 General Practitioner controls. Histories of patients and controls were compared by means of logistic regression., Results: Statistically significant trends were observed for the risk of urothelial cancer to increase with estimated lifetime consumption of cigarettes. Among ex-smokers, risks reduced with time since quitting, and ex-smokers who quit 20 or more years ago experienced risks similar to lifelong non-smokers. Type of cigarette was not an important predictor of risk. The two control series provided estimates of 45% and 33% respectively for the percentage of cancers in the series attributable to cigarette smoking., Conclusion: Cigarette smoking is the single most important cause of urothelial cancer, but stopping smoking leads quickly to reductions in risk.

TUMORS in children ,SMOKING - Abstract
Parental smoking data have been re-abstracted from the interview records of the Inter-Regional Epidemiological Study of Childhood Cancer (IRESCC) to test further the hypothesis that paternal cigarette smoking is a risk factor for the generality of childhood cancer. Reported cigarette smoking habits for the parents of 555 children diagnosed with cancer in the period 1980-1983 were compared, in two separate matched pairs analyses, with similar information for the parents of 555 children selected from GP lists (GP controls) and for the parents of 555 hospitalized children (hospital controls). When cases were compared with GP controls there was a statistically significant positive trend (P = 0.02) between the risk of childhood cancer and paternal daily consumption of cigarettes before the pregnancy; there was no significant trend for maternal smoking habit. When cases were compared with hospital controls there was a statistically significant negative trend (P < 0.001) between the risk of childhood cancer and maternal daily consumption of cigarettes before the pregnancy; there was no significant trend for paternal smoking habit. Neither of the significant trends could be explained by adjustment for socioeconomic grouping, ethnic origin or parental age at the birth of the child, or by simultaneous analysis of parental smoking habits. Relations between maternal consumption of cigarettes and birth weights suggested that (maternal) smoking data were equally reliable for case and control subjects, although comparisons with national data suggested that the hospital control parents were unusually heavy smokers. These findings give some support for the hypothesis that paternal cigarette smoking is a potential risk factor for the generality of childhood cancers. [ABSTRACT FROM AUTHOR]

Percentage fetal haemoglobins (% HbF) were measured in 7081 newborns at the University Hospital, Nottingham, between 1990 and 1992 to assess the effects of a range of factors, and to determine if there was an association between % HbF at birth and risk of SIDS (sudden infant death syndrome). Data from the obstetric clinical records were analysed by multiple linear regression to establish the major determinants of % HbF. New findings were the identification of maternal smoking, twin pregnancy, ethnic origin, and season of birth as significant determinants. Alcohol use, drug and vitamin intake, and duration of labour were not found to be important. The previously reported correlations between % HbF and sex, gestational age, and birthweight were confirmed, and the relative effects quantified. Overall, the major determinants of an increase in % HbF in neonates are similar to the known antenatal risk factors for sudden infant death syndrome (SIDS). [ABSTRACT FROM AUTHOR]
