Body weight and water ingestion estimates for women in two communities in the Philippines: The importance of collecting site-specific data

Abstract

In this paper, we report data on exposure factors relevant to assessing health risks of contaminant exposures to women of childbearing age (age 15–49) in two communities in the Philippines. We collected exposure factor data through an interview survey of 182 women conducted between January and May 2002 and we present distributions of self-reported body weight and water ingestion rates. A simple comparison of our results to those from large studies of US women suggests that these small subpopulations may both weigh less and consume more water than might be expected based on the extensive national US data, and it suggests that exposure analysts focused on a particular geographic area should consider the value of obtaining site-specific data to characterize exposure and risk. The lack of a comparable large study of water ingestion rates and body weights of Filipino women makes it difficult to determine whether the communities studied are typical of the population of the Philippines or represent unique subgroups. We suggest that Philippine health authorities consider the possibility of including questions about water ingestion rates in future national health or nutrition surveys.
