| Introduction: There are few studies about the relationship between dairy products consumption and BMI. This study was conducted to assess the relationship between milk consumption and body mass index in a group of Tehranian adults, selected from participants of the Tehran Lipid and Glucose Study (TLGS). Material and methods: 404 subjects (202 men and 202 women) aged over 16 years were included in this study. Dietary data was collected by means of a qualitative food frequency questionnaire for one year and two 24-hour dietary recalls. Height and weight were measured according to standard protocols and BMI was calculated. Mean (±SD) of age and BMI for men and women were 36±15 and 31±13 years and 24.6±4.5 and 24.9±5.1 kg/m2, respectively. Frequency of milk consumption was 15.1±13.4 and 14.8±13.7 times per month in men and women, respectively. Subjects with a frequency of ≥30 times per month, had a lower weight (67.1±1.5 vs 75±1.1 kg for men and 59±1.6 vs 66.4±1.2 kg for women, p<0.01 for both) and BMI (22.4±0.5 vs 25.6±0.3 kg/m2 for men and 23.6±0.4 vs 26.1±0.5 kg/m2 for women, p<0.01 for both) than persons with the frequency of < 10 times per month, after adjusting the effect of age, energy, carbohydrate and fat intake. The proportion of subjects consuming milk with a frequency of <10 times per month was higher among persons with BMI ≥30 than among persons with BMI<25 (51% vs 11% for men and 52% vs 14% for women, p<0.05). In contrast, the proportion of subjects with milk consumption frequency of ≥30 times per month were higher than persons with BMI≥30 (61% vs 7% for men and 58% vs 11% for women, p<0.05). The results suggest an inverse relationship between milk consumption and body weight and body mass index. It is recommended that further studies address this issue by adjusting for the effect of physical activity. |
