Resumo: BACKGROUND: It is well known that obesity is one of the most Public Health’s concerns especially among children. Recent data reports that childhood obesity in Portugal increased in the last years, representing nowadays 32.1% of overweight and 14.5% of obesity (1). Family, as the primary children source of social learning, habits and behaviors’ influence and exposure have shown a basic determinant to food and physical activity children’ choices (2,3,4). The role of family and parental factors in childhood obesity suggests that single-parent, no siblings and small family size are associated with larger increases in BMI (2,3,5,6). Family provides social and interpersonal support that is instrumental in shaping and maintaining eating and physical activity behaviors, community-based health programmes focus also on family educational policies and strategies have been developed in some European Countries, showing relevant impact on health patterns and a decrease on childhood obesity prevalence’s (7,8). METHODS: This study is framed from a longitudinal municipal project (MUNSI), which included 3173 children (6-9 years old) from 167 public schools conducted on five municipalities (Viana do Castelo, Fundão, Oeiras, Seixal and Montijo). Childhood nutritional status was assessed by anthropometric parameters (weight and height) considering the CDC growthcharts criteria percentiles of BMI. Children’s food habits, socioeconomic condition and parent’s level education were collected by a family questionnaire. The Odds Ratio was calculated with a 95% Confidence Intervals. RESULTS: Prevalence of childhood overweight (BMI≥P85) was 32.1%, and 14.3% for obesity (BMI≥P95). According to family characteristics the data showed that a small family size is associated with larger increases in BMI (OR=1.6; 95%CI: 1.1-2.3). It was also observed that having a lower level of education, a lower socioprofessional status and a household income of less than €1500 were risk factors statistically significant (p <0.05) for the development of childhood obesity, with an inversely association with the prevalence of childhood obesity. CONCLUSION: The data have shown that obesity was not independent from parent's socioeconomic and educative level, where these two conditions seem to be more likely to develop childhood Overweight. This knowledge identifies additional childhood obesity causes that could be useful as effective interventions at local level in order to reverse the obesity trends in Portuguese children and promote a future healthy life style.
