The main objective of the study is to assess the growth and expansion of public health(PH)research works by Bangladeshi authors from various perspectives such as quantum of growth,patterns of collaboration, and productivity of authorship, among others. The present research uses a scientometric technique to examine secondary literature. Between 2000 and 2015, 871literature by Bangladeshi writers and 3,71,389 literature by worldwide authors on PH were retrieved from the Scopus database and evaluated using quantitative indicators to study growth and development from various perspectives. The highest growth in terms of the number of publications has been observed in the year 2015(133) and the lowest in 2001(10). The PR(Percent of Growth Rate) shows that 2001 was the deepest decreasing year(-38%) whereas 2002was the most increasing year(90%). During the study, RGR(Relative Growth Rate) values of Bangladeshi contributions to PH literature varied from 0.16 to 0.55, with an average of 0.27. The CC(Collaborative Coefficient) value indicates that during the research period, there was a substantial amount of collaboration among the authors. At the same time, the PPA(Productivity Per Author) value(0.31) denotes that throughout the era, each Bangladeshi author produced less than half of a publication per year. The mean Activity Index(AI) during 2000-2015 was 89.14,which reflects lower activity than the world’s average in PH literature. It was also observed that research productivity in public health of Bangladesh follows Lotka’s inverse rule of author production. According to the findings, there is a strong link between public health research output in emerging and developed nations. 展开更多
