Abstract

This research is on prevalence of reported lactose intolerance and calcium intake among young adults in University Malaysia Sabah students, aged 19-29. A total of 529 of respondents were involved in this research. The objective of this research is to find out the prevalence of self-reported and diagnosed lactose intolerance among University Malaysia Sabah students. It also aims to determine the frequency and types of foods and drinks that are sources of calcium in the diet of self-reported lactose and diagnosed intolerance as compared to those who are lactose tolerant and to estimate the level of calcium intake in the diet of respondents using 3 days food diary in order to determine its adequacy as compared to the Recommended Nutrient Intakes (RNI) for Malaysia 2005 for calcium. This research employed a questionnaire, Food Frequency Questionnaire (FFQ) and 3-days food diary. To analyze the calcium intake of the respondents and the relationship of two variables, program SPSS software version 12.0 was used. Results showed that 33 (6.27%) of respondents reported themselves as being lactose intolerant. The FFQ showed a difference in intake of milk and milk product intake lactose intolerant and lactose tolerant respondents. Moreover, ice-cream was the highest consumption that is sources of calcium in the diet of self-reported lactose and diagnoses intolerance. The Mann-Whitney U test showed a significant difference in average daily calcium intake between lactose tolerant (555.44±.61.52mg/day) and lactose intolerant (510.94±.81.40mg/day) male respondents. Results also showed significant difference in average daily calcium intake among lactose tolerant female respondents (538.04±,62.19 mg/day) and lactose intolerant female respondents (474.52±.81.40 mg/day) (Z=0.00). However, no relationship was found between lactoseintolerance/ lactose tolerance and achieving the RNI for calcium (X2=0.148, p=0.701). As a conclusion, there is minority of students in University Malaysia Sabah reported themselves as being lactose intolerant.
