RESUMO
Impaired fetal growth and preterm birth are the leading causes of neonatal and infant mortality worldwide and there is a growing scientific literature suggesting that environmental exposures during pregnancy may play a causal role in these outcomes. Our purpose was to assess the environmental exposure of the Fetal Growth Longitudinal Study (FGLS) participants in the multinational INTERGROWTH-21(st) Project. First, we developed a tool that could be used internationally to screen pregnant women for such exposures and administered it in eight countries on a subsample (n = 987) of the FGLS participants. The FGLS is a study of fetal growth among healthy pregnant women living in relatively affluent areas, at low risk of adverse pregnancy outcomes and environmental exposures. We confirmed that most women were not exposed to major environmental hazards that could affect pregnancy outcomes according to the protocol's entry criteria. However, the instrument was able to identify some women that reported various environmental concerns in their homes such as peeling paint, high residential density (>1 person per room), presence of rodents or cockroaches (hence the use of pesticides), noise pollution and safety concerns. This screening tool was therefore useful for the purposes of the project and can be used to ascertain environmental exposures in studies in which the primary aim is not focused on environmental exposures. The instrument can be used to identify subpopulations for more in-depth assessment, (e.g. environmental and biological laboratory markers) to pinpoint areas requiring education, intervention or policy change.

We investigated the practice of some of health-compromising behaviours among Omani adolescents and their correlates in a nationally representative secondary school-based sample of 1670 boys and 1675 girls. The mean age of the sample was 17.13 (SD 1.35) years. Through a self-administrated questionnaire the adolescents were asked about 6 risky behaviours: current smoking, ever use of alcohol, succumbing to peer pressure to take illicit drugs, driving without a licence, speeding while driving and being involved in a physical fight in the month prior to the survey. Demographic and psychosocial variables related to their risk behaviours were also assessed. The results indicated that 4.6 % were current smokers, 4.3% had drunk alcohol and 4.6% had taken drugs. About 20% had been involved in a physical fight in the month prior to the survey, 33.4% drove without a licence and 33.9% liked to speed. Male sex and low self-esteem were the strongest predictors of risky behaviour.

We examined the knowledge, attitudes and practices of Omani adolescents with regard to reproductive health in a nationally representative secondary school-based sample of 1670 boys and 1675 girls. Through a self-administrated questionnaire the adolescents were asked about puberty, marriage, birth spacing and AIDS and sexually transmitted infections. Only half of the sample knew the changes at puberty of their own sex, while even fewer knew the changes in the opposite sex. Girls were inclined significantly towards later age of marriage than boys. The mean number of children desired by the sample was 4.9. About two-thirds of the adolescents had a positive attitude toward modern contraceptive methods and intended to use them in the future. Knowledge of fertility period was poor as was knowledge of AIDS and sexually transmitted infections. There was a high rate of approval (80%) of female genital cutting by both sexes.
