The impact of dairy product consumption on nutrient adequacy and weight of Head Start mothers.Public Health Nutr. 2009 Oct; 12(10):1693-701.PH
To assess the relationship of dairy product consumption on diet quality and weight of low-income women.
Head Start centres in Texas and Alabama, USA.
Cross-sectional study. Women were divided into dairy consumption groups: < or =1, >1 to < or =2 and >2 servings/d. Nutrient intake/diet quality was determined by calculating the percentage meeting the Estimated Average Requirement, guidelines for fat and added sugar, and Mean Adequacy Ratio (MAR). Mean BMI was compared for the dairy consumption groups.
Mothers with children in Head Start; 609 African-Americans (43 %), Hispanic-Americans (32 %) and European-Americans (24 %).
Fifteen per cent of participants consumed >2 servings of dairy products and 57 % consumed < or =1 serving of dairy daily. Intakes of protein, vitamin D, riboflavin, P, Ca, K, Mg and Zn were significantly higher in those consuming >2 servings/d. Total SFA were higher and added sugars were lower in those consuming >2 servings of dairy products daily compared with those consuming < or =2 servings/d. Forty-one per cent of women consuming >2 servings of dairy daily had MAR scores under 85 compared with 94 % consuming < or =1 serving/d. Mean BMI was 30.36 kg/m2; there was no association between BMI and dairy product consumption.
Consumption of dairy products was low and was not associated with BMI in this low-income population. Higher levels of dairy product consumption were associated with higher MAR scores and improved intakes of Ca, K and Mg, which have been identified as shortfall nutrients in the diets of adults.
