title: Process evaluation of the Los Angeles Unified School District Nutrition Network.
abstract: BACKGROUND
  This study evaluated the Los Angeles Unified School District Nutrition Network, a large multicomponent nutrition and physical activity program in an ethnically diverse school district, launched in 2000.
  
  
  METHODS
  We calculated descriptive statistics and performed hierarchical logistic regression on school-level demographic and implementation data.
  
  
  RESULTS
  Thirty-six percent of eligible schools participated in 2001, and 79% of participating schools reapplied the following year. Elementary schools and schools that applied for grant money were more likely to re-apply. Produce sampling was the most frequently cited program highlight, and making purchases with program grant money was the most frequently cited challenge.
  
  
  CONCLUSIONS
  Our findings suggest that schools serving students of low socioeconomic status and diverse ethnicities can be recruited into a large program to promote healthy dietary choices and physical activity, especially elementary schools. Effectiveness and institutionalization of the program might be positively affected by fostering local ownership, allowing school personnel who apply for the grant to tailor the program to their individual schools.
