Pilot study of dietary influences on mammographic density in pre- and postmenopausal Hispanic and non-Hispanic white women.

Objective: The extent to which modifiable dietary factors may account for some of the variability demonstrated in mammographic density across ethnic groups is unknown. The purpose of this study was to provide pilot data describing the relationship between dietary variables and mammographic density in pre- and postmenopausal Hispanic and non-Hispanic white (NHW) women (N=238) ranging in age from 41 to 50 years (premenopausal only) or 56 to 70 years (postmenopausal only).

Design: Using a cross-sectional design, computer-assisted density assessments were performed on mammograms of both breasts and averaged for analysis.

Population and parity levels of Aedes aegypti collected in Tucson.

Oviposition traps were used to follow changes in the population of Aedes aegypti (L.) (Diptera:Culicidae) in a seven-block area in midtown region of Tucson, Arizona. About 20,000 eggs were collected over a period from 1 June to 14 October 2000.
