RESUMO

The close relationship between obesity and the occurrence of chronic non-communicable diseases and the epidemic degree of its expansion makes this, amongst the public health problems, one of the most serious in the world. The main goal of this study was to estimate the spatial distribution of weight excess in adults in the South District of Campinas-SP. This is a population-based cross-sectional study with adults, selected through random sampling in two stages. In this study, it was characterized demographic variables in terms of housing and sanitation, nutritional status, food habits and lifestyle. Considering the ordinal nature of scales used to Body Mass Index (BMI) it was adjusted an Ordinal Logistic Regression model, known as Proportional Odds, having as the dependent variable the three levels of nutritional status (normal weight=1, overweight=2, obesity=3) and as predictive, variables selected in simple logistics settings. For the spatial distribution of weight excess, and to examine whether the increase in BMI occurs homogeneously in the territory, we make use of Geographic Information System (GIS) and spatial statistics. The results indicated the age, poor living conditions, quality of food and sedentary leisure time as aspects positively associated with increased BMI. It was possible to map the spatial distribution of weight excess in adults and to identify which aspects positively associated with increased BMI are distributed heterogeneously in the area
