Objective: The aim of this study is to evaluate the role of mothers' democratic, authoritarian, permissive, and overprotective parenting styles in childhood obesity and mothers' perception of their children's body weight. Method: The research was cross-sectional in design, and a total of 94 children aged between two and six years were included, together with their mothers. Mothers were administered the Parental Attitude Scale, and children's Body Mass Index (BMI) was classified using age- gender-specific tables of the International Obesity Task Force (IOTF). The effect of mothers' parental attitudes on their children's BMI groups was evaluated. However, mothers matched their child's appearance to the appearance they thought corresponded to the age and gender-specific weight plot and mothers' weight perceptions were evaluated. Results: The prevalence of overweight-obesity among children was found to be 19.2%. There wasn’t statistically difference between democratic, authoritarian, overprotective and permissive parenting styles and BMI categories of children (p=0.819, p=0.878, p=0.319, p=0.494). The mothers of overweight-obese children perceived their children as significantly overweight compared to other children (p
