Impact of school staff health on work productivity in secondary schools in Massachusetts.

Background: Healthy, productive employees are an integral part of school health programs. There have been few assessments of work productivity among secondary school staff. This study describes the frequency of 3 common health risk factors--obesity, depressive symptoms, and smoking--and their impact on work productivity in secondary school employees.

Healthy homes: in-home environmental asthma intervention in a diverse urban community.

Objectives: We evaluated health outcomes associated with in-home interventions in low-income urban households with children with asthma.

Methods: A comprehensive health and environmental assessment and subsequent intervention were completed in 116 households with 170 enrolled children with asthma. Home health workers provided household safety, asthma prevention education, and targeted environmental intervention to decrease asthma triggers and improve household safety.

Measurements of heart motion using accelerometers.

We have used acceleration sensors to monitor the heart motion during surgery. A three-axis accelerometer was made from two commercially available two-axis sensors, and was used to measure the heart motion in anesthetized pigs. The heart moves due to both respiration and heart beating.

Biographical, trait, and behavioral-sampling predictions of performance in a stressful life setting.

Biographical, trait, and behavioral-sampling predictors, when combined, yield a substantially and significantly larger prediction of performance, R = .72, in a natural setting than any of these approaches achieve separately (Rs, respectively, of .64, .
