Abstract/OtherAbstract:
BACKGROUND/OBJECTIVES:It has been postulated that a higher dairy consumption may affect blood pressure regulation. The aim of this study was to examine the association between dairy consumption and blood pressure in mid-childhood.SUBJECTS/METHODS:Subjects (n=335) were participants of a birth cohort at high risk of asthma with information on diet at 18 months and blood pressure at 8 years. Multivariate analyses were used to assess the association of dairy consumption (serves) and micronutrient intakes (mg). In a subgroup of children (n=201), dietary intake was also measured at approximately 9 years.RESULTS:Children in the highest quintile of dairy consumption at 18 months had lower systolic blood pressure (SBP) and diastolic blood pressure (DBP) at 8 years (2.5 mm Hg, P=0.046 and 1.9 mm Hg, P=0.047, respectively) than those in the lowest quintiles. SBP was lowest among children in the highest quintiles of calcium, magnesium and potassium intakes. Significant negative linear trends were observed between SBP and intakes of dairy serves, calcium, magnesium and potassium. Furthermore, SBP and DBP were lowest in the group of children that consumed at least two dairy serves at both 18 months and the follow-up dietary data collection at 9 years, compared with all other children (SBP 98.7 vs 101.0 mm Hg, P=0.07; and DBP 56.5 vs 59.3 mm Hg, P=0.006, respectively).CONCLUSION:These results are consistent with a protective effect of dairy consumption in childhood on blood pressure at age 8 years.European Journal of Clinical Nutrition advance online publication, 11 January 2012; doi:10.1038/ejcn.2011.218.
