Objectives: The Pittsburgh Influenza Prevention Project (PIPP) has previously shown that school-aged children in grades K-5 can learn hygiene-based, nonpharmaceutical interventions (NPIs) and persist in these behaviors over the duration of an influenza season. The purpose of this study was to determine whether age (as estimated by grade) plays any role in this ability., Methods: The Pittsburgh Influenza Prevention Project is a prospective, controlled, randomized trial of the effectiveness of a suite of NPIs in 10 elementary schools. The project measured adoption of NPIs by students through surveys of intervention homeroom teachers before, during, and after the influenza season and control home-room teachers after influenza season., Results: There were large, statistically significant improvements and persistence over time across all grade levels, in students' concern about influenza and their daily practice of NPIs that promote health behaviors-"wash or sanitize your hands often" and "cover your coughs and sneezes." Nonpharmaceutical interventions characterized as extinguishing unhealthy behaviors, such as "avoid touching your eyes, nose, and mouth" or "home is where you stay when you are sick," showed no reliable improvement., Conclusions: The study provides evidence that elementary school-aged children, across all grades, can understand and implement protective NPIs and maintain these activities throughout influenza season and beyond. Improvements were most prominent when teaching students to engage in health-promoting behaviors. Habitual behaviors (unconscious touching) and changing family behaviors (staying home) seem less susceptible to intervention. These results will be useful to public health policy makers and health care practitioners considering methods of infectious disease prevention in school-based settings.

Objectives: The purpose of this study was to determine to what extent school-aged children can learn hygiene-based nonpharmaceutical interventions (NPIs) and persist in these behavioral changes over the duration of an influenza season. If this can be done successfully, it may be a preferable pandemic mitigation strategy to much more disruptive strategies such as whole-scale school closure., Methods: The Pittsburgh Influenza Prevention Project (PIPP) is a prospective, controlled, randomized trial of the effectiveness of a suite of hygiene-based NPIs in controlling influenza and related illnesses in elementary schools in the City of Pittsburgh. During the 2007-08 school year, the project measured adoption of NPIs by students in five elementary schools through surveys of home-room teachers before, during, and after influenza season., Results: Results showed highly statistically significant improvement in students' daily practice of nearly all of the NPIs, including hand washing and sanitizer use and covering coughs and sneezes., Conclusions: The study provides evidence that children can learn, implement, and persist in the behaviors of a multilayered suite of NPIs over a typical flu season. These results will be useful to public health policy makers and practitioners considering methods of infectious disease prevention in school-based settings.

Objectives: Schools act as "amplifying sites" for the spread of infectious diseases, outbreaks, and pandemics. This project assessed which nonpharmaceutical interventions (NPIs) are most acceptable to parents and teachers of school children in grades K-5 to K-8 in Pittsburgh public schools., Methods: During the spring of 2007, the Pittsburgh Influenza Prevention Project surveyed 134 teachers and 151 parents representing nine elementary schools regarding attitudes toward NPIs and their usage by adults and school children during seasonal influenza outbreaks., Results: General etiquette practices such as covering coughs, handwashing, and using hand sanitizer were highly acceptable to both groups, while masks and gloves were not., Conclusions: The success of an NPI or a set of NPIs depends on both its efficacy and the feasibility of implementing it with relevant populations. If masks, gloves, and other more intrusive NPIs are to be used in community settings during a severe influenza season or pandemic, it is clear that there is significant preparatory work needed to increase acceptability on the part of the adults. Without such acceptance, it is highly unlikely that children and their supervising adults will participate.
