Project Details


Migrant farmworkers, especially female farmworkers, have been one of the
most underserved and understudied occupational populations in the United
States. The physically demanding and exerting tasks, as well as
potential environmental contamination, climatic extremes and unsanitary
conditions in the field, may well increase the risk for migrant female
farmworkers to develop health problems. The primary objectives of the proposed interview-based cross-sectional
survey is to study the effect of farmworker activities and exposures on
the reproductive health of women (aged 18-45) living in California
farmworker communities. The prevalences of reproductive health problems
and prevalence of post-natal problems between women who work as
farmworkers, as compared to those who do not, in relationship to any
specific occupational farmworker activities, will be determined and
compared. The investigators propose to undertake this study in two stages: a pilot
study and a full-scale study. In the pilot study an estimated 100-150
women, from randomly chosen households, from a selected and enumerated
farmworker community in one of the agricultural regions of California,
will be given a pretested questionnaire, as well as a limited physical
examination and blood and urine samples will be collected and analysed.
The purpose of the pilot study is to determine the feasibility of
implementing the study and to refine sample selection and data collection
methods. The pilot study will be completed in an 18-month period. The
full- scale study will be carried out, starting in 1993, in 4-5
communities representative of specific agricultural activities in
California farming regions will be selected, enumerated, and all women
aged 18-45 will be interviewed in person. In both studies farmworking
women will be considered "exposed", while women staying at home or are
working in other than farmlabor will be considered "unexposed" and will
serve as the comparison group. In the data analysis, relative risk will be estimated for menstrual cycle
irregularities, spontaneous abortions, premature deliveries, and abnormal
post-natal development of infants, while also controlling for potential
confounders such as age, weight, parity, smoking, past medical history,
access to and use of medical care, and nutrition. Funding for a two-year
period is requested to conduct the pilot study and to assess and refine
it for the implementation of the full-scale study.
