Making sense of the evidence: modelling biopsychosocial pathways to birthweight

The final chapter in Part 2 draws together the evidence from the previous two chapters with the aim of constructing a theoretically justifiable and biologically plausible model of the complex biopsychosocial pathway to birthweight. The next, and final, part of the book explores how the model might contribute to more effective programmes promoting optimum birthweight (see Chapter 7) and the research and policy implications of the model (see Chapter 8).
