Protocol for the development of the WHO gestational weight gain charts.

ABSTRACT:

Introduction

Gestational weight gain (GWG) is an important indicator of maternal nutrition to be monitored during pregnancy. However, there is no evidence-based tool that can be used to monitor it across all geographic locations and pre-pregnancy body mass index (BMI) categories.

This protocol describes all the steps that will be used to accomplish the development of these GWG charts.

Methods and analysis

This project will involve the analysis of individual participant data (researcher-collected or administrative). To identify eligible datasets with GWG data, a literature review will be cond
