2000 Stories: Victorian Intergenerational Health Cohort Study
Synopsis
2000 Stories is comprised of the Victorian Adolescent Health Cohort Study (VAHCS) and the nested intergenerational study, Victorian Intergenerational Health Cohort Study (VIHCS).
The VIHCS, launched in 2006, is one of the first prospective multi-generational studies in the world to look at how a parent’s (VAHCS participant) lifestyle, health and behaviour before pregnancy (including the teenage years), as well as during and after pregnancy, might influence their child’s health and development. It is one of the first longitudinal studies of childhood psychosocial development to be embedded within an existing longitudinal study of parent development and aims understand the processes that might influence many aspects of health and wellbeing across generations.

| Study focus | In the past fifty years we have seen unprecedented changes in the pattern of transition from reproductive maturity (at puberty) to first parenthood. The average gap between reproductive maturity at puberty and first childbirth in Australian women is now almost 2 decades. This widening gap coincides with changes in young adult lifestyles, health problems and behavioural risks that have relevance, not only for an individual’s later life health, but for the start to life that she/he may give to offspring. This study explores the extent to which risks that emerge in these transition years of adolescence and young adulthood may predict pregnancy risks, birth outcomes, postnatal maternal mental health and maternal child attachment in the first year of life. The study has now been extended to further follow up offspring in childhood, allowing us to examine the extent to which preconception predictors may predict child and parental outcomes at age 8 |
| Sampling frame | The sample frame comprised all active members of the Victorian Adolescent Health Cohort (VAHCS) who reported having a child between the recruitment phase (2006 and 2014). 1635 active study members were contacted at six-monthly intervals during the recruitment phase, via email, telephone and text message. Study members were invited to participate if they or their partner was pregnant or had a child born in the past 12 months. |
| Year commenced | 2006 |
| Commencement sample | The commencement sample comprises all infants for whom one or more interviews were completed during the recruitment phase (Waves 1-3), totalling 1026 children born to 662 parents |
| Annual attrition rate | N/A (the three perinatal waves completed to date form the recruitment phase) |
| Intergenerational? | This nested intergenerational study is embedded within VAHCS (The Victorian Adolescent Health Cohort Study) |
| Imaging | No |
| Linkage | Yes, linkage to (at least one) administrative dataset completed |
| Biosamples? | No |
| Ethics approvals or requirements? | All parents provided informed consent. Before data collection, we provided the participants with details of the content of the assessment and we obtained verbal consent before assessment completion. The data collection protocols were approved by the Human Research Ethics Committee of the Royal Children’s Hospital (Victoria, Australia) |
