Abstract
Background
Health literacy (HL) plays a key role in explaining health disparities. School nurses provide health related expert knowledge and skills within the school setting. A positive effect on the HL of children but also their teachers and parents is assumed and supported by some research but gaps persist in the available data.
Methods
As part of a pilot school nursing project, which placed school nurses in 28 public schools in two German states, all teachers, parents and students (11+ years) attending the schools were invited to participate in a 2017 baseline (T0) and 2018 follow-up (T1) survey. Adult HL was measured using the HLS-EU-Q16 and child HL with the HLSAC. Bi- and multivariate analyses were carried out.
Results
Comparing T0 and T1, HL scores improved in all populations. In East Germany (Brandenburg), the percentage of teachers with problematic or inadequate HL decreased from 56.6 (N = 173) to 51.5 (N = 173) and among parents from 45.7 (N = 1719) to 43.2 (N = 1080). In West Germany (Hessen), the percentage of teachers with problematic or inadequate HL also decreased, from 43.7 (N = 201) to 42.2 (N = 263), and among parents from 42.2 (N = 2013) to 34.9 (N = 1251). The percentage of children that scored in the moderate or high HL brackets increased from 77.9 (N = 898) to 82.2 (N = 736) in Brandenburg and from 84.9 (N = 1379) to 86.5 (N = 1487) in Hessen. There were strong statistical relationships between child/parental HL and child health behaviors in all datasets. The T0 and T1 comparison showed some improvements over time.
The presence of school nurses in public schools seemed to increase health awareness, thus contributing to a “healthy school.” After a short period (18 months) and despite a rather nonspecific spectrum of interventions, the HL of all relevant target groups improved. Further research is needed to quantify the relative contribution of the school nurses to improvements in HL, for example, by implementing a HL curriculum in a controlled setting.
Key messages
The presence of a school nurse seemed to increase health awareness contributing to a “healthy school.” After 18 months of intervention, the health literacy of children, parents and teachers improved.
