The influence of family attitudes and behaviours regarding nutrition and exercise has been highlighted as a pivotal determinant in promoting healthier choices among children. This study aims to explore the relationship between family nutrition and physical activity practices and children's attitudes toward physical activity. Methods A descriptive cross-sectional study was conducted with 633 children and their parents from a tertiary hospital in eastern Turkey. Data were collected using three tools: (1) a sociodemographic form, (2) the Family Nutrition and Physical Activity Screening Scale (FNPASS), and (3) the Youth Physical Activity Attitude Scale in Children and Young People. Data were analysed using SPSS software and statistical analyses included Pearson correlation, linear regression, and ANOVA to explore associations and group differences. Results Family nutrition and physical activity practices significantly predicted children's physical activity attitudes. Physical activity positive attitudes (mean score: 3.74 +/- 0.88) correlated strongly with healthier family practices (FNPASS mean: 52.44 +/- 7.65; r = 0.648, p < 0.01), while physical activity negative attitudes (mean: 2.46 +/- 0.92) showed inverse relationships (r = -0.596, p < 0.01). Higher parental education, urban residency, and income levels were associated with more physical activity positive attitudes (p < 0.001). Underweight children had higher positive attitude scores than overweight/obese peers (p < 0.001). Conclusion Family environments significantly influence children's physical activity attitudes, with socioeconomic factors acting as key modifiers. This study demonstrates that family nutrition and physical activity practices significantly influence children's attitudes toward physical activity. Healthier family habits correlated with more positive attitudes in children, particularly among families with higher parental education and urban residency. Public health initiatives should focus on educating parents about healthy practices while ensuring equitable access to physical activity opportunities for children.en10.1186/s12889-025-24230-winfo:eu-repo/semantics/openAccessFamilyChildrenNutritionActivityFamily NutritionPhysical ActivityHealth BehavioursArticle2-s2.0-105014609830
