Impact of New Zealand teenagers' fertility intentions on childbearing.

Abstract

Objective: To assess the impact of age 15 fertility intentions on childbearing outcomes three decades later.

Background: Evidence is mixed about the implications of teenage fertility intentions on later childbearing. Taking a prospective life course approach to assessing intentions and outcomes may help clarify these mixed findings.

Method: A general population birth cohort (born 1972/73) was asked about their fertility intentions at age 15 and 775 of this sample (384 women, 391 men) provided data on their childbearing between ages 15 and 45.

Results: At age 15, almost all of the sample indicated they would like to have children in the future (93%). Most (79%) reported having had a biological child by they time they were 45; but those who professed to not wanting children as teenagers were significantly less likely to have had a child three decades later.

Conclusion: Fertility intentions during adolescence are probably influenced by social, political and economic norms and may influence later childbearing decisions. This may be particularly true for those whose intentions counter established norms around childbearing.

Implications: A life course framework is useful for examining the relationship between hypothetical fertility intentions and outcomes.
