As the accessibility-enhanced multimedia informational education reduced patient anxiety and improved satisfaction with the information and materials received, it can be adapted to complement patient education in future regular cardiac care.

This is a preliminary study design aimed at creating a program for reducing children's ETS exposure at home. Further research to produce evidence supporting the application of the parent-child interactive program in primary schools is suggested. The theoretical basis of the intervention design can serve as a reference for nursing education and the design of health education programs.

Inheritance of a major susceptibility gene for breast cancer has been primarily investigated in families with early-onset disease. However, familial clustering of late-onset breast cancer is well documented, and genetic factors may also be relevant. In the Iowa Women's Health Study, we evaluated evidence for a major gene after allowing for measured environmental risk factors. Two hundred sixty-five incident breast cancer probands were identified from a prospective cohort study of 41,837 women aged 55 to 69 years at baseline in 1986. A pedigree development form was mailed to the probands to ascertain all first-degree female relatives. A questionnaire and body measurement protocol were mailed to identified living relatives or surrogates. Segregation analyses were conducted on a total of 1,145 women in 251 families using regressive models as implemented in S.A.G.E. Mendelian codominant inheritance of an allele that produced an earlier-age-at-onset provided the best fit to the data. Incorporation of measured environmental risk factors as covariates yielded no significant improvements in the likelihoods. Approximately 50% of this population could be expected to carry a late-onset breast cancer susceptibility gene, and 23% of the population is susceptible because of the environment in which they live. Homozygous gene carriers are predicted to have a mean age-at-onset of 48 years, over 20 years earlier than heterozygotes; few cases would be expected among non-gene carriers. In conclusion, the transmission pattern of late-onset breast cancer may be determined by a common susceptibility gene.

Parental smoking is the major source of children’s secondhand smoke exposure and is influenced by parents’ perception of children’s exposure. However, the factors associated with these perceptions remain unclear. The objective of this study was to examine factors associated with parents’ perceptions about parental smoking in the presence of children and its consequences. We conducted a cross-sectional study on parents’ perceptions of parental smoking and measured their evaluations of its consequences using a self-report questionnaire. Other variables include socio-demographic characteristics and smoking-related experience. Results show that parents’ gender, education level, occupational type, smoking status, and agreement on a home smoking ban independently predict parents’ evaluation of the consequences of parental smoking in the presence of children. Parents’ gender, education level, annual family income, smoking status, agreement on a home smoking ban, and evaluation of the consequences of parental smoking independently predicted parents’ perceptions. Findings indicated that a specific group expressed greater acceptance of parental smoking and was less aware of its risks. Motivating parents to create a smoke-free home and increasing awareness of the adverse consequences of parental smoking is beneficial in reinforcing attitudes opposed to parental smoking.
