To identify school community readiness to adopt a school-based adolescent nutrition intervention.

Cross-sectional study: mixed-methods design. The community readiness model was used to guide instrument development and qualitative analysis. Quantitative data are presented using descriptive statistics. Each statement was rated on a seven-point Likert scale, thereby producing scores between 1 (strongly disagree) and 7 (strongly agree).

Ten of the twenty current public secondary schools in Bogor, Indonesia.

Ninety teachers and ten school principals.

Eating behaviour problem awareness was present among all participants; awareness of efforts to improve eating habits was also present, but these efforts were perceived as having low efficacy; support from the City Education Authority and Health Authority was present, but the support type did not match the perceived needs; nutrition education had not been implemented across the entire school community due to competing priorities; existing nutrition policies did not provide concrete scenarios and clear guidelines for nutrition-friendly schools; the availability and accessibility of healthy foods at schools were considered to be key factors in improved adolescent nutrition; positive attitudes existed among respondents towards the implementation of various nutrition programmes, and the median and mode were seven in all types of school-based intervention.

The school community readiness level regarding school-based adolescent nutrition interventions is currently in the action phase, implying that community leaders have begun organising efforts to address issues in adolescent nutrition and are aware of their consequences. Future support should be directed towards improving existing efforts and offering concrete ideas and clear policy guidelines for implementation.
