Low dietary diversity and its influencing factors among a San group in Namibia

Research output: Contribution to journalArticleScientificpeer-review

Abstract

Objective

Although the San in Namibia have been targeted by intensive development efforts, there is little knowledge available about San diet quality and nutritional status. The objective of this study is therefore to estimate and quantify the dietary diversity of a San group, and to investigate how socioeconomic characteristics affect dietary diversity. The dietary data (n = 200) for this cross-sectional study were collected as a part of a larger doctoral research investigating food environment, food choices, and dietary changes of the Khwe San in Bwabwata National Park East.

Results

The mean dietary diversity score (DDS) of the participants was 2.44 out of 10, with only two people having a DDS of 5. 87.5% of participants consumed only from 2 or 3 different food groups, mainly grains/roots and dark green leafy vegetables. DDS significantly correlated only with the level of education and with age. Due to their collinearity, the group with no education had the lowest DDS, but also belonged to the oldest age group. The overall dietary diversity of the Khwe is extremely low, indicating severe nutritional inadequacy. The small differences in DDS among the socioeconomic groups indicate the importance of other determining factors, such as cultural and food environmental characteristics.
