  • Objective To investigate relations between milk consumption and lactose intolerance (LI) in adults and to explore the effect of milk consumption on lactase activity.Methods Total of 182 subjects aged 20-70 years were recruited and interviewed by questionnaires,and their accumulative cow's milk intake (AMI) was calculated.LI was evaluated by hydrogen breath test (HBT).Results A negative correlation was found between AMI and severity of observed LI symptom (r=-0.2884; P<0.05).Binary logistic regression analysis showed a negative correlation between LI and duration and frequency of milk consumption (OR,0.317 and 0.465,respectively; both P<0.05) and a positive correlation between LI and amount of milk consumed per sitting (OR,6.337; P<0.05).Conclusion LI is related to various milk consumption behaviors.Most Chinese adults with LI may tolerate moderate milk consumption <160 mL.
