Nutrient intakes and cholesterol values of the parents in a prospective randomized child-targeted coronary heart disease risk factor intervention trial--the STRIP project.
OBJECTIVE
To analyze food consumption, nutrient intakes and serum cholesterol concentrations of the parents in a child-targeted CHD intervention trial, during which the age of children increased from 7 months to 5 y.


METHODS
The children were randomized to an intervention group (n = 540) or a control group (n = 522) at six months of age. The intervention families were counseled at 3-6 month intervals to reduce their child's intake of saturated fat and cholesterol. Dietary issues were discussed with the control families only briefly. The parents' food consumption was analyzed by 24 h dietary recall at the child's age of 7 and 13 months and at 2, 3, 4, and 5 y. Nutrient intakes were calculated using the Micro-Nutrica program.


RESULTS
The mothers and fathers of the intervention children used less butter, more margarine and more skim milk than those of the control children (P < 0.001 for all measurements). After the onset of counseling, the intervention mothers consumed continuously less fat (1.4 E% less at the child's age of 5 y), less saturated fat (1.5 E% less at the child's age of 5 y) and more polyunsaturated fat (0.5 E% more at the child's age of 5 y) than the control mothers (P = 0.008, P < 0.001 and P < 0.001 for trend, respectively). After the child's age of 13 months the intervention fathers also had a continuously lower fat intake (2.4 E% less at the child's age of 5 y) and consumed less saturated fat (1.5 E% less at the child's age of 5 y) than the control fathers (P < 0.001 for trend for both measurements). The serum cholesterol concentration of the intervention mothers was consistently lower than that of the control mothers during the intervention (at child's age of 5 y 4.86 and 5.09 mmol/L, respectively; P for trend = 0.03), while the values of the intervention and control fathers showed no differences.


CONCLUSIONS
Continuous dietary intervention begun in infancy and focused on modification of the child's diet according to the current principles of preventive cardiology, was accompanied by a moderate decrease in the intake of total and saturated fat in the parents, but serum cholesterol concentration diminished consistently only in the mothers of the intervention children.
