Maternal tobacco smoking and childhood obesity in South Africa: A cohort study.

Background: Tobacco use and obesity are major public health problems and part of the leading causes of preventable disease and death worldwide. The prevalence of overweight children has escalated over the years; making the weight gain in children a critical issue for health professionals and academics alike. This study examines the association between maternal tobacco use and body weight abnormalities among South African children.

Closer together or farther apart: are there club convergence in ecological footprint?

This study empirically tests whether there is evidence of convergence in ecological footprint among 189 countries for the period 1990-2017. Using the novel log (t) regression model that accommodates likely transitional heterogeneity in the panel, the results provide evidence for the divergence of ecological footprint (EF) for the world sample. A similar empirical outcome was obtained for sub-Saharan Africa (SSA), Europe and Central Asia (ECA), East Asia and Pacific (EAP), Latin America and the Caribbean (LAC), and Middle East and North Africa (MENA).

Spatial impact of foreign direct investment on ecological footprint in Africa.

This study examines the spatial impact of FDI on ecological footprint of 31 African countries. In achieving this, the study uses the Driscoll-Kraay (1998) random effect model, fixed-effect instrumental variable regression, and the spatial Durbin model. There are three main important findings from this empirical study.
