The positive correlation between parent and child blood lipids is established, as is the association between body mass index (BMI) and blood lipids. However, the relative importance of each has not been examined.

PURPOSE: The purpose of this descriptive research project was to determine if blood lipids for African American (AA) girls were more highly correlated with maternal blood lipids or with the child's BMI.

METHODS: Blood was drawn from apparently healthy, 12–14-hr fasted AA mothers and daughters (n = 44 and 66, respectively) and heights and weights were measured. Data were blocked by BMI for normal weight (BMI > 25), overweight (BMI 25-29.99), and obesity (BMI > 30) and ANOVA tests run to determine differences in blood lipids between the groups. Correlations were run between all variables, divided into mother's vs daughter's, and correlation tests were run between mother and daughter TC, LDL and HDL.

RESULTS: The child's blood lipids were significantly correlated with maternal blood lipids (LDL r = .40, p < 0.01; HDL r = .20, p < 0.05; TC r = .32, p < 0.01). Daughters' LDL and TC were not significantly correlated with their own BMI however daughter's HDL was negatively correlated with daughter's BMI (r = .36 p < 0.01). There was not a significant difference for blood lipids between BMI groups (normal weight, overweight, and obesity).

CONCLUSION: A child's blood lipids are positively correlated with the mother's blood lipids and HDL is negatively correlated with BMI.
