Interventions aimed at encouraging parents to talk to their children about sex should enhance parents' understanding of the stages of children's sexual development and focus on the parents of young children. In addition, interventions should support parents in a range of strategies that complement discussions about sex.

Proportional hazards models are used to test hypotheses about the effect of women’s prior childbearing on the probability of having a birth in remarriage and to analyze the effects of other factors. Results indicate that the number of children at the time of remarriage has no effect on childbearing probabilities, but the age of the youngest child has a significant effect. These findings support the view that having a child is important to confirm the marriage, but that individual and family life course factors also affect the decision to have a child in a remarriage.

Research and interventions concerning parent-child communication about sex should not neglect the role of fathers. However, some fathers may need support to overcome barriers to effective communication, especially with their daughters.

BackgroundIn the United States, nearly half of high school students are sexually active, and adolescents experience high rates of unintended pregnancy and sexually transmitted diseases. Parents can have an important influence on their children's sexual behaviour, but many parents do not talk with their children about sexual topics. Research has shown significant differences in parent-child communication about sexual topics depending on the gender of both the parent and the child. Little is known, however, about the reasons for these gender differences. The purpose of this paper is to describe how factors associated with parent-child communication about sexual topics differ by gender.MethodsData are from a nationwide online survey with 829 fathers and 1,113 mothers of children aged 10 to 14. For each of the four gender groups (fathers of sons, fathers of daughters, mothers of sons, mothers of daughters), we calculated the distribution of responses to questions assessing (1) parent-child communication about sex-related topics, and (2) factors associated with that communication. We used chi-square tests to determine whether the distributions differed and the false discovery rate control to reduce the likelihood of type I errors.ResultsWith both sons and daughters, fathers communicated less about sexual topics than mothers did. Fathers also had lower levels of many characteristics that facilitate communication about sex (e.g., lower self-efficacy and lower expectations that talking to their children about sex would have positive outcomes). Compared with parents of sons, parents of daughters (both mothers and fathers) talked more about sexual topics, were more concerned about potential harmful consequences of sexual activity, and were more disapproving of their child having sex at an early age.ConclusionsUsing a large national sample, this study confirms findings from previous studies showing gender differences in parent-child communication about sexual topics and identifies gender differences in factors that may influence parent-child communication about sexual topics. Interventions designed to support parent-child communication about sexual topics should emphasize to both mothers and fathers the importance of talking to sons as well as daughters. Fathers need particular support to overcome the barriers to communication they encounter.
