Analysis of the dietary diversity status of agricultural households in the Nkomazi Local Municipality, South Africa

Abstract

BackgroundDietary diversity is a good alternative measure of the nutritional adequacy and food security. The present study assessed the household dietary diversity status and its determinants among agricultural households in the Nkomazi Local Municipality, South Africa.MethodsOut of 543 households in the study area that were supported by the Phezukomkhono Mlimi programme during the 2018/19 production season, only 355 met the inclusion criteria and consented to participate in this study. The data were analysed using descriptive statistics, computation of the Household Dietary Diversity Score (HDDS) and the ordered logit regression model.ResultsMost of the respondents were elderly (56.10%) and females (59.44%). Most had low levels of education (43.66%) and low farm income (96.34%). In addition, most (65.35%) had large households. The majority (49.86%) of the households in the study area had a HDDS of 4.40, while the median HDDS in the study area was 3.90. Over the recall period, the majority of households consumed cereals (100%) and vegetable (78.31%) food types. Households headed by respondents with no formal education had lower odds (OR = 0.20; 95% CI 0.06–0.61) of having a higher dietary diversity compared to those headed by heads who had attained tertiary education. Households with income ≤ R3000.00 had lower odds (OR = 0.51; 95% CI 0.31–0.85) of having a higher dietary diversity as compared to those with income > R3000.00. Households with 1–5 members had higher odds (OR = 10.41; 95% CI 1.05–103.20) of having a higher dietary diversity as compared to larger households. With every unit increase in the age of the household head, the odds of the household of having a higher dietary diversity increased by 1.03 (OR = 1.03; 95% CI 1.01–1.05).ConclusionSince cereals and vegetables dominated the diets of the respondents, findings of this study highlight the need for improved access to sources of protein among the respondents. Therefore, there is a need for programmes to educate respondents on the dangers of inadequate nutrition (lacking in protein). Strategies that enhance farm income and the level of education among respondents should be prioritised because of their potential to boost Household Dietary Diversity (HDD) in the study area. Collaborations between different stakeholders, such as nutritionists, extension workers and researchers, should be encouraged so as to develop a holistic approach to improving the HDD in the study area.
