BACKGROUND: Some studies have reported an inverse association between dairy product (DP) consumption and weight or fat mass loss. OBJECTIVES: The objective of our study was to assess the association between DP intake and abdominal obesity (AO) among Azorean adolescents. SUBJECTS/ METHODS: This study was a cross-sectional analysis. A total of 903 adolescents (370 boys) aged 15-16 years was evaluated. Anthropometric measurements were collected (weight, height and waist circumference (WC)) and McCarthy's cut-points were used to categorize WC. AO was defined when WC was ≥90th percentile. Adolescent food intake was assessed using a self-administered semiquantitative food frequency questionnaire and DP intake was categorized in <2 and ≥2 servings/day. Data were analyzed separately for girls and boys, and logistical regression was used to estimate the association between DPs and AO adjusting for potential confounders. RESULTS: The prevalence of AO was 54.9% (boys: 32.1% and girls: 70.7%, P<0.001). For boys and girls, DP consumption was 2.3±1.9 and 2.1±1.6 servings/day (P=0.185), respectively. In both genders, the proportion of adolescents with WC <90th percentile was higher among individuals who reported a dairy intake of <2 servings/day compared with those with an intake <2 servings/day (boys: 71% vs 65% and girls: 36% vs 24%, P<0.05). After adjustments for confounders, two or more DP servings per day were a negative predictor of AO (odds ratio, 0.217; 95% confidence interval, 0.075-0.633) only in boys. CONCLUSION: We found a protective association between DP intake and AO only in boys.
