A bibliographic review of sustainability research output and investment in 10 leading public health journals across three time periods.

Long-term delivery, or sustainability, of evidence-based interventions is necessary for public health benefits to be realised. However, sustainment of effective interventions is poor. Understanding the evidence-base and identifying potential gaps is necessary to inform where future research efforts are most warranted. We undertook a repeat cross-sectional bibliographic review of research published in 10 public health journals across three time periods (2010, 2015 and 2020/2021). Studies were eligible if they were a data-based study or review article. Studies were assessed as to whether they focused on sustainability. The percentage of public health research studies assessing sustainability overall and by the three time periods was calculated. The association between time period and the proportion of sustainability articles was assessed using logistic regression. Descriptive statistics were used to summarise study characteristics overall and by time period. 10,588 data-based articles were identified, of which 1.3 % (n = 136) focused on sustainability. There was a statistically significant association between time period and the proportion of sustainability research, with a slight increase across the three time periods: 0.3 % (95 % CI: 0.1 %, 0.7 %) in 2010, 1.4 % (95 % CI: 1.0 %, 1.9 %) in 2015 and 1.6 % (95 % CI: 1.3 %, 1.9 %) in 2020/2021. Most research was descriptive/epidemiological (n = 69, 51 %), few focused on measurement (n = 2, 1.5 %) and none on cost effectiveness. Only one intervention study assessed the effect of specific sustainability strategies. This bibliographic review highlights the need for more public health research on sustainability, particularly in the areas of measurement, sustainability interventions, and cost effectiveness.
