A correlation study of nutrition and factors influencing food choices among construction workers

Abstract: Nutrition is known to be linked with worker health and safety (H&S) performance. Literature suggests that construction workers have poor nutrition and this adversely affects their health, wellbeing and safety on construction sites. Strategies to improve their nutrition warrant considerable attention. This paper aims to identify significant relationships between factors influencing nutrition and the food choices of construction workers. Empirical data for the correlational study were collected through a field questionnaire survey on site construction workers in the Gauteng Province of South Africa. Principal components analysis and Pearson‘s correlation analysis were conducted. Findings revealed that food context, nutritional knowledge, resources and personal ideas and systems were significantly associated with choice of foods. By highlighting the factors which are correlated with nutritional choices amongst construction workers, the study provides valuable evidence which will allow for the development and implementation of efficient and successful intervention programs geared towards improving construction workers' nutrition and thus site safety performance
