Abstract

Lactose intolerance (LI), a risk factor for low bone mineral density (BMD), is the most common type of carbohydrate intolerance, which predominantly affects Southeast Asian populations. However, data on the prevalence of LI and its association with BMD among Malaysian adults are still lacking as not much research has been done on this matter. Thus, the aims of this study are to determine the prevalence of LI and to evaluate its association with BMD among students of Universiti Kebangsaan Malaysia. A total of 100 Malay students (50 males and 50 females) with mean age of 23.9 ± 4.7 years old and body mass index of 24.5 ± 5.8 kg/m2 were selected to involve in this preliminary study. After an overnight fast, subjects were asked to perform hydrogen breath test (HBT) and lactose tolerance test (LTT) after an intake of 300 ml lactose drink (50g lactose). HBT measurements were recorded at every 30 minutes intervals while LTT results were recorded at fasting and 30 minutes after lactose consumption. Visual analogue scales were used to measure gastrointestinal symptoms. BMD was measured at calcaneus bone using quantitative ultrasound and expressed as T-score. A consistent rise by >20 ppm for HBT and failure of blood sugar to rise by >1.10 mmol/L above basal level were considered as abnormal HBT and LTT. Lactose malabsorption (LM) is defined by abnormal HBT and LTT whilst LI is characterized by having abnormal HBT, LTT and gastrointestinal symptoms. The result showed that 86% male and 90% female subjects exhaled breath hydrogen >20 ppm but there was no significant difference (p>0.05) between them. LTT results showed that 86% male subjects failed to rise their blood sugar level >1.10 mmol/L compared to 60% in female subjects. Both male and female subjects had high percentage occurrence of gastrointestinal symptom (82 % and 80% respectively) although no significant difference (p>0.05) was demonstrated. The prevalence of LI and LM among all subjects was 77% and 18% respectively but no significant difference (p>0.05) between genders. In contrast, only 5% of the subjects were lactose tolerance. Male subjects were found to have significantly higher (p<0.05) T-score (1.32 ± 1.52) compared to female subjects (0.75 ± 1.22). However, no significant (p=0.264) association between LI and BMD was shown in this study. To conclude, LI does not directly influence BMD. However, reduce calcium intake from milk and milk products due to avoidance of LI could lead to reduce BMD and osteoporosis in the long term. Therefore, corrective measures should be taken to encourage Malaysian population to increase the intake of milk and milk products.
