• Description:
  Objective:
  
  This study sought to describe and compare study type, research design and translation phase of published research in nutrition and dietetic journals in 1998 and 2018.
  
  Design:
  
  This was a repeat cross-sectional bibliographic analysis of Nutrition and Dietetics research. All eligible studies in the top eight Nutrition and Dietetics indexed journals in 1998 and 2018 were included. Two independent reviewers coded each study for research design (study type and study design) and translation phase (T0-T4) of the research using seminal texts in the field.

  Results:
  
  The number of publications (1998 n=1030, 2018 n=1016) has not changed over time but the research type, design and translation phases have. The proportion of intervention studies in 1998 (43.8%) was significantly higher than 2018 (19.4%). In 2018, more reviews (46.9% vs 15.6% in 1998) and less randomised trials (14.3% vs 37.8% in 1998) were published. In regards to translation phase, there was a higher proportion of T2-T4 research in 2018 (18.3% vs 3.8% in 1998); however, the proportion of T3/T4 research was still low (<3%). Our sensitivity analysis with the four journals that remained the same across the two time periods found no changes in the research type, design and translation phases across time.
  
  Conclusions:
  
  There was a reduction in intervention and T0 publications, alongside higher publication of clinical study designs over time; however, published T3/T4 research in Nutrition and Dietetics is low. A greater focus on publishing interventions and dissemination and implementation may be needed.
