Estimated rate of weight change per year by multi-level regression model. Data were collected from 1995 to 1999 from Nigeria, Jamaica and the United States (US). Only individuals who have all three weight determinations are included (completers).
* Sample size. † Δ weight = weight change in kilograms per year. ‡SE = standard error.
