Food security, Food consumption, San Tome and Principe, Consumption pattern, Sub-saharan Africa, Latent Class Models


The aim of this article is two-fold: (1) firstly, we intend to conduct a very quickly comparative analysis in Africa, in the food security issue, and (2) secondly, to uncover the pattern on San Tome and Principe population consumption. In order to do this we used data collected from questionnaires in 1996, 2002 and 2010 and Latent Class Models for data analysis. As results, (1) concerning comparative analysis we find two clusters, thus finding that African countries are heterogeneous, considering food security issue, and (2) as for San Tome and Principe inhabitants consumption, we concluded that eating habits experienced a great change between 1996 and 2008 in terms of frequency of consumption of food products including meat. This change was influenced by the increases registered in socioeconomic factors such as marital status, status in employment, education level and income.

In this study we demonstrate that the basic food products at the three districts that we scrutinize are banana, matabala and breadfruit (local production) and rice (imported and donated). The consumption of local produce (or domestic production) is higher in rural districts. In short, considering the available data on food availability we concluded that the nutritional situation of the country has been experiencing improvements since the year 1996.
