Title: Randomised Double-blind Placebo-controlled Trial to Evaluate the Impact of Vitamin A on Maternal Mortality in Ghana
Brief Summary: Main objectives: To evaluate the impact of weekly vitamin A supplementation (VAS) to women of reproductive age (15-45 years) on maternal mortality in rural Ghana, and to compare this with the impact on overall mortality.

Hypotheses:

1. Weekly supplementation with vitamin A (7000 µg retinol equivalent \[RE\]) to reproductive age women will reduce maternal deaths by 33%.
2. This impact will be achieved by reductions in both pregnancy-related and non-pregnancy-related deaths.
3. There will be a reduction in non-maternal deaths, similar in size to that in maternal non-pregnancy related deaths.

Outcome measures: Maternal mortality rate, and overall mortality rate. Deaths will be identified through monthly demographic surveillance, and classified as maternal (pregnancy-related, non-pregnancy-related) or non-maternal using verbal autopsies.
