Abstract

Work output is driven by energy supply from the food we eat. Manual workers are some of the most active people in our society and their ability to balance energy consumption and expenditure is crucial, especially for work productivity and nutritional health. However, studies on energy requirement for work productivity are limited. The objective of this study was to determine the correlation between the choice of the main carbohydrate staple and preference ranking by Very Active Manual Workers (VAMW) in Nairobi. Questionnaires were administered to 322 respondents categorized into three groups: VAMW, and moderately active civil servants (CS) and university students (US). Respondents were asked to state their main carbohydrate staple and rank six commonly consumed carbohydrate foods from most preferred to the least preferred. Ugali was ranked first with a mean rank value of 1.134 ± 0.492, followed by chapati with a mean rank of 2.588 ± 0.976, and the third was rice with a mean rank of 3.247 ± 1.242. Irish potato came fourth with a mean rank value of 4.299 ± 0.970, and bananas had a mean rank value of 4.588 ± 1.068. The “others” mixed category was least preferred, ranked sixth with a mean rank value of 5.165 ± 1.297, 95% confidence level. Analysis of Variance suggested a significant difference in preference ranking for different carbohydrate staples by the VAMW, F (0.05, 5,576), P < .0001. The pairwise comparison of mean ranks indicated a significant difference between the rank means of all pairs, but there was no significant difference between mean ranks of rice versus chapati, and Irish potatoes versus bananas. Correlation analysis revealed a very weak correlation between the preference ranking and occupation (activity level), r value 0.109 for all respondents, and r value 0.024 for VAMW. There was a moderate correlation between the main carbohydrate staple and preference ranking of all groups combined, r value 0.562; but r value 0.516 for VAMW; 0.598 for US; and 0.595 for CS. Regression analysis indicated the main staple was a good predictor of the preference ranking, 32.4%, F (6,303) = 24.167, p < .000. The hypothesis tested was that there is no correlation between the main carbohydrate staple and preference ranking by VAMW. Approximately 29.7% of the variation in the preference ranking was predicted by the main staple of VAMW compared to for 32.4% for all respondents combined. Only 29.7% of the variation in the preference ranking by VAMW was predicted by the main staple, suggesting other factors contribute to variation in preference ranking by VAMW.
