The messages from this month's summaries are hugely important from the international perspective.
Modern research in the epidemiological field would have been unthinkable last century because the long-term data would not have been available and the resources to capture it unaffordable. Massive financial and human investment in nutritional studies, plus the technology to interpret the information, are leading to global conclusions.
The macro- and micro-nutrition of mothers and children up to two years of age are clearly shown to determine long-term outcomes, while longitudinal studies of oral contraceptive (OC) use forty years ago are now affecting old women's health.
Concepts such as disability-adjusted life-years (DALYs) and intra-uterine settings are just the start as mega- and meta-analysis drive our views to include new confounding variables in our assessments in Obstetrics and Gynaecology. The positive news about OCs must surely eventually lead to their wider and easier availability which will breach so many existing hindrances to women's health.
