RESUMEN
Children obesity is a serious public health issue. This study aimed to investigate physical/sedentary activities of first-year primary schools children in Modena, and their association with overweight/obesity and dietary habits of children and family characteristics to identify the risk factors for unhealthy lifestyles. Child physical/sedentary activities were gathered through an anonymous questionnaire administered to parents, as well as family characteristics and weight/height of child and parents. Logistic regression models, eventually adjusted for parents' sociodemographic characteristics, were used to analyze data. Questionnaires were delivered by 660 families (74.2%), of which 72 without anthropometric data were excluded. Three out of four children spent in physical activities less than 7 h/week, while 63.9% dedicated to sedentary activities two or more hours/day. From multivariate analysis, the habit significantly affecting children's overweight/obesity was spending time on tablets/Personal Computers/mobile phones/videogames. Higher parental education level resulted in a protective factor for implementing unhealthy lifestyles in terms of time dedicated to physical/sedentary activities. Our results suggest the need of interventions to increase time for physical activity and to promote a responsible use of digital media involving the entire families to reach all parents regardless of their education and nationality with a possible relapse on other family members.

Over the last four decades, childhood overweight/obesity has dramatically increased, becoming a significant public health concern. The main aims of this study were to investigate the prevalence of overweight/obesity among first-year primary schools children in Modena and to identify the associated risk factors. Data were collected on the socio-demographic characteristics of family and weight, height, dietary habits and sedentary behaviours of the children, and on the parents' perception of their child's weight status, through an anonymous questionnaire administered to parents. The questionnaires were delivered by 660 out of 890 (74.2%) families, and after excluding those without anthropometric data, 588 children were included in the study. The prevalence of overweight/obesity among the children was 25.2%, significantly lower in children born to parents with a high education, and higher among children born to foreign parents and overweight/obese mothers. The multivariable analysis showed that the children most likely to become overweight/obese were those who skipped breakfast (OR 2.3, 95%CI 1.3-4.2) and/or mid-morning snacks (OR 3.2, 95%CI 1.5-6.5). Breakfast consumption was positively associated with higher parental education levels, whereas skipping mid-morning snacks is more frequent among children born to foreign parents and overweight/obese mothers. Moreover, 84.7% of the parents of overweight/obese children underestimated their child's weight status. One in four 6-7 year-old children is already overweight or obese. Childhood overweight/obesity is significantly associated with unhealthy lifestyles and family lifestyle. It is therefore essential to implement public health intervention programs aimed at both parents and children, in order to promote healthy lifestyles in early childhood.
