Trial of an intervention to reduce passive smoking in infancy.
We tested a health education intervention program to reduce passive smoking in infancy. The aim was to develop an instrument for study of tobacco smoke exposure and childhood respiratory illness. One hundred and eighty-four women who had smoked during pregnancy were allocated by month of delivery to an intervention group, to a minimal contact group, or to a follow-up only comparison group. Exposure to smoke was assessed 3 months later by questionnaire and by measurement of cotinine in samples of maternal and infant urine. There was a reduction in maternal smoking associated with contact with research staff, but this was not statistically significant. There were no differences between the groups in the exposure of infants to tobacco smoke. Reasons for this finding may include the timing of the intervention, the heterogeneity of the target group, and the manner in which information was presented on health risks caused by parental smoking.

Physical activity preferences, preferred sources of assistance, and perceived barriers to increased activity among physically inactive Australians.
BACKGROUND: Participation in regular moderate or vigorous physical activity substantially reduces risk for all-cause and cardiovascular-disease mortality and confers other health benefits. Efforts to decrease the population prevalence of inactivity will have a greater impact if they are tailored to the needs and preferences of the community. METHODS: In the Pilot Survey of the Fitness of Australians, a questionnaire was administered to a randomly selected sample of 2,298 adults and included questions on the preferred sources of assistance or support to become physically active, preferred activities, and barriers to regular participation. The responses of those who were identified as insufficiently physically active (n = 1,232; 53.6%) were examined for men and women separately and for those aged 18 to 39, 40 to 59, and 60 to 78 years. RESULTS: The most-preferred activity was walking (38 and 68% of the youngest and oldest age groups, respectively). The most frequently cited barriers to more-regular participation in the youngest age group were insufficient time, lack of motivation and child care responsibilities. Among those aged 60 to 78 years, injury or poor health were the most frequently cited barriers to activity. The most-preferred source of advice or assistance changed with age: more than 50% of the oldest age group wanted advice from a health professional (compared with 22% of the youngest group) and the opportunity to exercise with a group was the most preferred source of support for the youngest age group. CONCLUSIONS: The physical activity-related attributes of men and women and of younger and older age groups described in this study may be used to provide more relevant and appealing options for those who might otherwise be missed by "one-size-fits-all" physical activity promotion strategies.

Can psychiatric and chemical dependency treatment units be smoke free?
The feasibility and appropriateness of establishing smoke-free psychiatric and chemical dependency treatment units are topics of recent interest. This paper reviews the literature on the implementation of smoke-free policies in psychiatric and chemical dependency treatment units. Several issues are addressed including (a) the concerns raised by treatment staff regarding the implementation of a smoke-free policy, (b) the effects of involuntary smoking cessation or reduction on the treatment and/or recovery of patients, (c) the utilization of smoking cessation interventions by patients and staff, and (d) the effects of a smoke-free environment on the smoking behavior of patients and staff. It is concluded that a smoke-free environment is a reasonable and achievable goal in these settings. However, the implementation of a smoke-free policy in chemical dependency treatment units has met with several more problems than those observed in psychiatric settings. Recommendations for further clinical research and program implementation are offered.

Inactive Australian college students' preferred activities, sources of assistance, and motivators.
a cross-sectional survey was sent to students at four college campuses to assess self-reported physical activity, sources of assistance to exercise, and motivators for regular activity . The study focused on 864 (40%) of 2148 students surveyed who were classified as inactive. Attributes of inactive male and female college students differed by gender. such differences may be used in tailoring health promotion interventions to increase physical activity.

Promoting reduced smoking rates in the context of workplace smoking bans.
A randomized study was conducted in 41 workplaces to determine the potential of self-help and group-based programs to encourage reduced smoking in workplaces that have implemented smoking bans. The trial had limited success in recruiting smokers, attrition was an important limitation, and the study outcomes were modest. The authors conclude that more research is needed on effective strategies that help smokers minimize smoking at work.
