A study of the relationship between health awareness,
lifestyle behaviour and food label usage in Gauteng
Introduction
The World Health Organization (WHO) advocates that consumers
should adopt healthier lifestyle behaviour, and has put international
strategies in place that promote healthier eating patterns, in support
of a healthier lifestyle.
1,2
In March 2010, South Africa published the
first phase of its new food-labelling legislation to reinforce this. The
legislation intends to create better health awareness, and subsequent
improved lifestyle behaviour among South African consumers.
3,4
A healthy lifestyle is defined as “orientation toward the prevention
of health problems, and the maximisation of personal well-being”.
5
USA consumers, who followed a healthy lifestyle, were found to
average a higher consumption of fruit and vegetables, were largely
female, had a higher level of education, and were predominantly
older than consumers who adhered to an unhealthy lifestyle.
6
Most
of these indicators contribute towards Kraft and Goodell’s idea of
“wellness-orientated” consumers who accept responsibility for their
own health through their daily lifestyle practices, including food-
purchasing choices.
7,8
Unhealthy food choices have been blamed partially for the worldwide
increase in obesity.
9
The Medical Research Council’s technical report
on chronic diseases of lifestyle in South Africa, conducted between
1995-2005, indicated that there was a high prevalence of obesity
in South Africa, with nearly 56% of women, and 29% of men, being
either overweight, or obese.
10
These figures suggest that if healthy
food choices and improved lifestyle behaviour are not promoted at
an early age, obesity will become an even greater concern in the
future. International food companies, blamed for the unhealthy food
choices that consumers make, are being forced to address better
nutrition by developing healthy product lines to improve the quality
of food offered to consumers.

Food labelling in South Africa also has a purpose to inform and
indirectly assist the consumer in making healthier food choices
Abstract
Background: The objectives of the study were to determine whether consumers who read food labels, were also more aware of health and
lifestyle issues, in terms of nutrition and other health-related lifestyle behaviours, and whether there was a relationship between food-label
reading, health awareness and lifestyle behaviour. A quantitative descriptive (survey) design was selected to investigate the relationship
between food-label reading on the one hand, and health awareness and lifestyle behavior on the other.
Method: A two-stage, stratified-proportionate and systematic sampling strategy was applied to select a sample of 357 Gauteng respondents
to complete a telephonic questionnaire. Respondents who were most likely to read food label information were selected. Food label information
is prescribed by comprehensive label legislation. Data report on respondents’ label-reading habits, attitudes towards health awareness,
lifestyle behaviour and biographic data. Nonparametric analysis, scale reliability tests, analysis of variance (ANOVA) and Bonferroni multiple
comparisons of means tests were used to analyse the results.
Results: Results indicate that the two-thirds of respondents who, to some extent read nutritional information on food labels, were concerned
about their personal health, were interested in health-related information, and followed a healthy lifestyle, such as regularly eating fresh fruit
and vegetables, cutting back on alcohol, and other positive lifestyle behaviours. They were unsure about how their own knowledge of nutrition,
and their understanding of nutrition information on food labels, compared with that of other consumers.
Conclusion: A relationship was found between patterns of reading food labels, health awareness and lifestyle behaviour. People who often
read food labels were more health-conscious, and maintained a healthier lifestyle.
