Abstract

Background

Consumption of fruits and vegetables reduces the risk of obesity, diabetes, cancer, cardiovascular mortality and all-cause mortality. The study assessed the pattern of intake and the factors that influence daily intake of commonly available fruits and vegetables in economically disadvantaged South African communities.

Methods

This is a cross-sectional study nested on an ongoing longitudinal study in South Africa. Two communities (a rural and urban) of low socio-economic status were purposely selected from two of the nine provinces. A sample of 535 participants aged 30–75 years was randomly selected from the longitudinal cohort of 1220; 411 (78%) women. Data were collected using validated food frequency and structured interviewer-administered questionnaires. Descriptive and multivariate regression analysis were undertaken.

Results

A higher proportion of participants in the urban township compared to their rural community counterparts had purchased fruits (93% vs. 51%) and vegetables (62% vs. 56%) either daily or weekly. Only 37.8% of the participants consumed at least two portions of commonly available fruits and vegetables daily, with no differences in the two communities. Daily/weekly purchase of sugar sweetened beverages (SSBs) was associated with daily intake of fruits and vegetables (p = 0.014). Controlling for age and gender, analysis showed that those who spent R1000 (USD71.4) and more on groceries monthly compared to those who spent less, and those who travelled with a personal vehicle to purchase groceries (compared to those who took public transport) were respectively 1.6 times (AOR, 95% CI: 1.05–2.44; p = 0.030) and 2.1 times (AOR, 95% CI: 1.06–4.09; p = 0.003) more likely to consume at least two or more portions of fruits and vegetables daily. Those who purchased SSBs daily or weekly were less likely (AOR, 95% CI: 0.54, 0.36–0.81, p = 0.007) to consume two or more portions of fruits and vegetables daily. The average household monthly income was very low (only 2.6% of households earned R5000 (US$357.1); and education level, attitude towards fruits and vegetables and owning a refrigerator had no significant association with fruits and vegetable daily intake.

Conclusion

These findings indicate that affordability and frequency of purchase of sugary drinks can influence daily intake of fruits and vegetables in resource-limited communities.
