Smartphone addiction has become a growing public health concern among adolescents. Excessive smartphone use has been associated with physical inactivity, mental health problems, and unhealthy lifestyle behaviors that may contribute to abnormal body mass index (BMI). This study aimed to examine the association between physical activity level, body mass index, and smartphone addiction among adolescents. A cross-sectional study was conducted among 102 adolescents, 15–17 years old in Surakarta, Indonesia. Data were collected using a structured questionnaire including demographic characteristics, the Smartphone Addiction Scale–Short Version (SAS-SV), and the International Physical Activity Questionnaire (IPAQ). BMI was calculated based on measured height and weight. The prevalence of smartphone addiction was 52.9%. Most participants had normal BMI (52.0%), while 28.4% were obese. Low physical activity levels were observed in 42.2% of respondents. Chi-square analysis indicated a borderline association between physical activity level and smartphone addiction (p = 0.054), suggesting a tendency for lower physical activity to be associated with higher smartphone addiction. No significant association was found between BMI and smartphone addiction (p = 0.084), nor between physical activity level and BMI (p = 0.359). Smartphone addiction was highly prevalent among adolescents. Although physical activity showed a potential association with smartphone addiction, BMI was not significantly correlation to either smartphone addiction or physical activity. These findings showed that the importance of promoting regular physical activity as part of preventive strategies against smartphone addiction among adolescents.
