Abstract

This research aims to describe and compare the association of the environment with health, biological rhythms, diet and lifestyle among daytime and night workers residing in rural and urban areas. This project is a result of collaboration between the Federal University of Acre and the University of São Paulo, in which the focus is on the rubber tappers of Chico Mendes Extractive Reserve located in Xapuri- Acre. In addition to the rubber tappers, in the present research, three other groups living in different environments will participate in the study: daytime workers residing in the urban area of Chico Mendes Extractive Reserve, Xapuri-AC; daytime workers residing in the urban area of São Paulo-SP, and night workers also residing in the urban area of São Paulo-SP. Sociodemographic and lifestyle data of 160 participants (n=40 in each group) will be collected through questionnaires. Anthropometric measurements will be done as well. In addition, participants will respond to a 24-hour food recall for three consecutive days, and will be collected samples of blood and saliva for evaluation of biochemical indicators (fasting glucose, fasting insulin, triglycerides, total cholesterol and fractions and melatonin). Conventional descriptive statistics (with position and dispersion measures) will be run using the software Statistical Package for Social Sciences 19.0 for Windows. To obtain dietary standards, a factor analysis by principal component analysis will be carried out, having food groups previously defined as variables. Inferential statistical analyzes will be performed using Stata 13 software, considering a significance level of 5% (p <0.05). (AU)
