Objective:  This study aimed to determine the prevalence of food insecurity among schoolchildren living in urban and rural areas of Picos, Piauí associated with the socioeconomic profile of families and their food intake and nutritional status.    Methods:  Study participants were families with children aged 7-10 years enrolled in municipal schools, totaling 342 families/schoolchildren. The study was conducted at school facilities through interviews with mothers - or guardians - using a questionnaire based on the Brazilian Food Insecurity Scale and socioeconomic variables and food frequency questionnaire. The nutritional status of children was assessed using the following indexes: weight/age, height/age and body mass index/age.    Results:  The prevalence of food insecurity was high and similar for rural and urban areas, 84.3% and 83.3%, respectively. In general, lower income and consumption of untreated water was associated with greater frequency of food insecurity (p≤0.01). In urban areas, higher percentage of food insecurity was associated to lower educational levels (p≤0.05). Dietary intake and nutritional status of schoolchildren were not associated with food insecurity condition of families.    Conclusion:  The percentage of families at food insecurity, as well as the food consumption and nutritional status of schoolchildren were similar between urban and rural areas, characterized as a homogeneous population in terms of socioeconomic conditions
