Introducing nutritional principles of preventive cardiology to the care of young children may improve permanently adherence to a low-saturated-fat, low-cholesterol diet later in life. This approach has not been readily adapted because of worries of the possible effects of such a diet on the growth and development of children. In the STRIP baby project, 1062 infants were randomized at 7 months of age into an intervention group (n = 540) or a control group (n = 522). The counselling of the intervention children aimed at a fat intake of 30% of energy after the age of 1 year and to a 1:1:1 ratio in saturated:monounsaturated:polyunsaturated fat intake. Dietary intake, growth and serum lipid concentrations were monitored in the children regularly through the first years of life. The intake of total fat, saturated fat and cholesterol were lower and the intake of polyunsaturated fat and the ratio of polyunsaturated to saturated fat (P/S) in the diet were higher in the intervention children than in the controls. During the first 3 years of the trial, the serum cholesterol concentration was 3-6% lower in the intervention children than in the controls (95% CI for the mean difference between groups from -0.27 to-0.12 mmol/L). No differences in the growth of the children were observed between the groups. We conclude that repeated individualized counselling aiming at reduced consumption of saturated fat combined with regular follow-up is effective and does not restrict the growth of children.

The effects of dietary intervention, sex, and apolipoprotein E phenotype on tracking of serum lipid values in young children have remained poorly characterized. We investigated these associations in 1062 infants who were randomized into control and intervention groups (n=522 and n=540, respectively) at age 7 months; the intervention group received counseling aimed at maintaining a low-saturated fat, low-cholesterol diet. In 519 children in the control (n=254) and intervention (n=265) groups, serum lipid values were studied annually between 13 months and 5 years of age. In all children, tracking was strongest for the ratio of high density lipoprotein (HDL) cholesterol to total cholesterol; when a 13-month-old child belonged to the lowest quartile of the distribution, the odds ratio for belonging to the same quartile at older ages was 39.0 (95% CI 23.1 to 66.0). Dietary intervention did not influence the tracking of serum lipids. Tracking of HDL cholesterol was stronger in the boys than in the girls ( P =0.018). Tracking of non-HDL cholesterol and apolipoprotein B in the children with phenotypes E2/3 or E3/3 was stronger than that in the other children ( P =0.031 and P =0.014, respectively). In conclusion, the apolipoprotein E phenotype strongly influences tracking of non-HDL cholesterol and apolipoprotein B values in early childhood, whereas dietary intervention had no effect on tracking of any of the lipids. A child’s sex influenced tracking only of HDL cholesterol, with boys showing stronger tracking.

Objectives: To evaluate the effects of diet, serum cholesterol concentrations, and apolipoprotein E phenotype on neurodevelopment of 5-year-old children. Study design: Prospective, 4.4-year cohort study in 496 children. Fat-modified diet was introduced to intervention families of 7-month-old infants. Control children consumed an unrestricted diet. Nutrient intakes, serum cholesterol, and neurodevelopment were studied. The groups were combined in univariate and stepwise multivariate logistic regression analyses. Results: In 13-month-old boys (girls), energy intake was 996 (938) kcal, fat intake 26.6 (26.4) percent of energy (E%), and protein intake 17.2 (17.4) E%. In 5-year-old boys (girls), the intakes were 1484 (1364) kcal, 32.1 (31.9) E%, and 15.5 (15.9) E%, respectively. The intakes of total fat and saturated fat and serum cholesterol were not associated with neurodevelopment. In boys, high intake of protein at 5 years, high intakes of protein at 4 years and cholesterol at 2 years, and high intake of polyunsaturated fatty acids at 3 years predicted favorable outcomes in the tests of speech and language skills, gross motor function and perception, and visual motor skills, respectively. Apolipoprotein E phenotype did not influence the test performance. Conclusions: Moderate restriction of dietary fat has no unfavorable effects on neurodevelopment in early childhood. However, the quality of fat and the relative intake of protein may influence neurodevelopment of the boys. (J Pediatr 2002;140:328-33)

Adult dyslipidemias may reveal familial and, therefore, offspring dyslipidemias. We evaluated the prevalences of the adult-offspring dyslipidemias in 441 general population families composed of both parents and one 5-year-old child. Family members were classified using the 90th or 10th percentiles for hypercholesterolemia (IIA), hypertriglyceridemia (IV), combined hyperlipidemia (IIB), and low high density lipoprotein cholesterol concentration without hyperlipidemia (hypoHDL). In familial combined hyperlipidemia (FCHL), the IIB-phenotype was in one generation and one of the three hyperlipidemias in the other generation. Finally, the parental dyslipidemia phenotypes and elevated lipids (>80th percentile) that reveal offspring dyslipidemia were selected by stepwise logistic regression. Either the IIA-, IV- or hypoHDL phenotype was found in both generations in 2.8, 2.0 and 1.4% of the families, respectively. FCHL was seen in 1.8% of the families, which confirms the earlier views. The predictive values of the elevated parental cholesterol, type IV or hypoHDL parents to find type IIA, IV and hypoHDL children were low for systematic screening: 16, 13 and 15%, respectively. However, 44% of the children of IIB parents expressed hyperlipidemia (odds ratio 4.7, P=0.006). The IIB phenotype of the parent is a good predictor of the child's hyperlipidemia, and when encountered, it indicates that the lipids of the child should be studied. This would be as important as selective screening of familial hypercholesterolemia.

Plant sterol supplementation reduces serum cholesterol concentration but may increase serum plant sterol concentrations, especially in children. We determined whether natural dietary plant sterols derived mainly from vegetable oil or margarine in early childhood affect serum concentrations of plant sterols (campesterol and sitosterol) and cholesterol precursor sterols (Delta-8 cholestenol, desmosterol, and lathosterol), reflecting endogenous cholesterol synthesis. We measured the serum sterol concentrations using gas liquid chromatography in 20 healthy 13-mo-old intervention children in a randomized, prospective study designed to decrease exposure of the children to known environmental atherosclerosis risk factors and in 20 control children. The diet of the intervention children was rich in plant sterols due to replacement of milk fat with vegetable fat, whereas the diet of the control children contained only small amounts of plant sterols. The intervention children consumed twice as much plant sterols as the control children (P < 0.001). Their serum concentrations of campesterol and sitosterol were 75% and 44% higher, respectively, than those in the control children (P < 0.001 for both), but serum cholesterol precursor sterol concentrations did not differ between the two groups. We conclude that doubling dietary plant sterol intake almost doubles serum plant sterol concentrations in 13-mo-old children, but has no effect on endogenous cholesterol synthesis. Relative intestinal absorption of natural plant sterols from the diet in early childhood is similar to that in adults.

Background —We showed previously that repeated dietary counseling during the first 3 years of life reduces the concentration of serum nonfasting cholesterol. We have now extended the study to children 5 years of age and analyzed fasting blood samples, enabling LDL cholesterol calculations for the first time. Methods and Results —Families of 7-month-old infants (n=1062) were randomized to a control group (n=522) or an intervention group (n=540) that received individualized dietary counseling with the aims of a fat intake of 30% to 35% of daily energy, a saturated/monounsaturated/polyunsaturated fatty acid ratio of 1:1:1, and a cholesterol intake of P P =0.052). Five-year-old intervention boys had 9% lower mean serum LDL cholesterol concentrations than the control boys ( P =0.0002; 95% CI, −0.39 to −0.12 mmol/L), whereas no difference was observed in girls. In both sexes, serum triglyceride concentrations were similar in the 2 groups. Conclusions —The restriction of saturated fat and cholesterol intake by repeated, individualized dietary counseling since infancy resulted in lower serum total and LDL cholesterol concentrations at 5 years of age. However, the effect was significant only in boys.

Objective: To investigate cholesterol-lowering efficacy and safety of plant stanol ester margarine in healthy 6-year-old children already consuming a low-saturated-fat, low-cholesterol diet. Study design: Eighty-one intervention children from the STRIP project, a randomized prospective trial aimed at reducing exposure of young children to the known environmental atherosclerosis risk factors, were recruited to this double-blind crossover study at 6 years of age. In randomized order the families were advised to replace daily 20 g of the child’s dietary fat intake with plant stanol ester margarine or control margarine for 3 months. The washout period lasted 6 weeks. Statistical analysis was performed according to intention-to-treat principle with analysis of variance for crossover design. Results: The mean daily plant stanol ester margarine consumption was 18.2 g (1.5 g plant stanol). The well-tolerated plant stanol ester margarine reduced serum total and low-density lipoprotein cholesterol concentrations by 5.4% and 7.5%, respectively ( P =.0001 for both). The serum high-density lipoprotein cholesterol and triglyceride concentrations and α-tocopherol to low-density lipoprotein cholesterol ratio remained unchanged. The serum β-carotene to low-density lipoprotein cholesterol ratio decreased by 19% ( P =.003). Conclusion: Plant stanol ester margarine significantly diminishes serum total and low-density lipoprotein cholesterol concentration without adverse clinical effects in healthy children who already consume a low-saturated-fat, low-cholesterol diet but decreases the serum β-carotene to low-density lipoprotein cholesterol ratio.(J Pediatr 2000;136:503-10)

STRIP (the Special Turku coronary Risk factor Intervention Project) is an ongoing intervention trial which aims at a permanent reduction in the intake of saturated fat and cholesterol starting in childhood. A total of 75 intervention and 63 control children was studied consecutively at the ages of 7 and 13 mo, and 2, 3 and 5 y to evaluate the influence of such intervention on serum cholesterol ester (CE) fatty acid composition, a widely used biomarker of fatty acid intake. Analysis of 4-d food records showed that total intake of fat and of saturated fat increased with age in both groups of children but was constantly lower in intervention than in control children, e.g. at the age of 5 y the mean intakes of total fat and of saturated fatty acids were 31.1 E% and 33.9 E% and 12.1 E% and 14.6E% in intervention and control children, respectively (p = 0.009 and 0.0001, respectively). Serum CE fatty acid compositions did not differ between the 2 groups at any age; the mean proportion of CE linoleic acid was 52.4% and 52.0% in 5-y-old intervention and control children, respectively. Correlation analysis showed, however, that the percentage of linoleic acid and of polyunsaturated fatty acids in CE reflected well the respective dietary intakes (r= 0.36; p = 0.0001 for both coefficients). In conclusion, CE fatty acid composition did not differ between the intervention and control groups, whereas CE linoleic and total polyunsaturated fatty acids reflected well the differences in their intakes at the individual level.

The purpose of this study was to examine patterns of physical activity (PA) during a single weekend to ascertain possible relationships between PA and anthropometry, fundamental motor skills, and CHD risk factors among 105 normal male and female children, aged 3–4 years. The children played, when awake, on the average for 14 hr, 16 min indoors and for 5 hr, 12 min outdoors of which low activity playing accounted about 4 hr. Notable gender differences were observed in the intensity of PA but not in fundamental motor skills and CHD risk factors. The results suggest that physical activity is weakly related to fundamental motor skills and CHD risk factors at an early age. The association between PA and body size was modified by gender (p = .024): The girls who played indoors a lot were heavier than the others, and the boys who played much more outdoors were heavier in relation to other boys. The associations between PA and motor skills as well as PA and CHD risk factors were also highly gender-dependent: The boys benefited from interacting with parents, while the girls benefited from independence. The most influential factors seemed to be the amount of playing outdoors, the amount of high level play activities, as well as interaction with parents.

Context: The important role of neuropeptide Y (NPY) in the regulation of food intake and energy balance has been firmly documented in rodents, but human data are sparse. The recently identified functional Leu7Pro polymorphism in the signal peptide region of the prepro-NPY is a useful tool for the investigation of the role of NPY in men. Pro7 substitution has been associated with the following: plasma NPY concentration, the risk factors of cardiovascular disease, birth weight of children, serum triglyceride concentration, and the function of vascular endothelium. Objective: The objective of this study was to analyze the connection between Leu7Pro polymorphism and relative weight, nutrient intakes, and serum lipids in early childhood. We closely followed 647 healthy Finnish children participating in the Special Turku Risk Factor Intervention Project through their first 9 yr of life. Results: Leu7Pro polymorphism showed no relation to intakes of energy, macronutrients, or the relative weight in either gender. However, Pro7 substitution was associated with serum triglyceride concentration in boys at the ages of 5, 7, and 9 yr. Conclusion: The functional Leu7Pro polymorphism is not likely to be involved in the regulation of adiposity or major nutrient preferences in childhood. In boys, the Pro7 variant may have impact on serum triglyceride concentration.

Objective. We studied whether the serum leptin concentration at age 2 years predicts changes in relative body weight by age 8 and whether the serum leptin concentration is associated with intake of energy and nutrients at age 5.Methods. A total of 156 8-year-old participants of the Special Turku Coronary Risk Factor Intervention Project were chosen to represent children whose relative weight decreased, was stable, or increased during the preceding 6 years. Their serum leptin concentrations were measured in samples collected when they were 2 years. Serum leptin was also measured in 100 5-year-old children in the Special Turku Coronary Risk Factor Intervention Project whose energy and nutrient intakes were analyzed using 4-day food records.Results. The boys whose relative weight decreased (n = 25), was stable (n = 28), or increased (n = 26) between 2 and 8 years of age had similar serum leptin concentrations at the age of 2 years. The girls whose relative weight decreased (n = 27) had higher serum leptin concentrations at 2 years than the girls whose relative weight remained stable (n = 26) but only when the leptin values were not adjusted for body mass index. The serum leptin concentration was higher in 5-year-old girls than in 5-year-old boys even when adjusted for body mass index. Serum leptin correlated with relative weight in girls and boys (r = 0.65 and r = 0.45, respectively). Serum leptin concentration adjusted for relative weight correlated poorly with intakes of energy, fat, saturated fat, carbohydrates, sucrose, and protein.Conclusions. Serum leptin concentrations at age 2 poorly predicted changes in relative body weight during the following 6 years and poorly reflected the intake of energy or major nutrients at age 5.

High serum cholesterol concentration is one of the key risk factors in development of atherosclerosis, which may begin early in life and later progress to symptomatic coronary heart disease. In adults, apoE polymorphism strongly influences cholesterol metabolism, as subjects with apoE 3/4 or 4/4 (collectively called apoE4) phenotype absorb cholesterol effectively and thus also have higher cholesterol absorption-reflecting plant sterol concentrations in serum than subjects with other apoE phenotypes. Because of the inverse correlation of absorption and synthesis of cholesterol, concentrations of cholesterol synthesis-reflecting serum cholesterol precursor sterols are lower in subjects with apoE4 than in subjects with other phenotypes. To analyze whether apoE phenotype affects cholesterol absorption and synthesis in early childhood, we measured serum plant sterol (campesterol and sitosterol) and cholesterol precursor sterol (desmosterol and lathosterol) concentrations in healthy 13-month old children using gas-liquid chromatography. The 36 study children were participants in a randomized prospective trial (the Special Turku Coronary Risk Factor Intervention Project) aimed at decreasing exposure of the children to environmental atherosclerosis risk factors. The 16 apoE4 children had 30% to 50% higher cholesterol-adjusted campesterol and sitosterol concentrations in serum than the 20 apoE 3/3 children (p = 0.002 and p = 0.02, respectively). The concentrations of cholesterol precursor sterols in serum did not differ between the two groups of children. We conclude that the young apoE4 children may absorb cholesterol and plant sterols more effectively than the children with apoE 3/3 phenotype without compensatory reduction in endogenous synthesis of cholesterol.

To evaluate the effect of dietary low-saturated fat, low-cholesterol intervention on fat intake and fatty acid compositions in serum cholesterol ester (CE), phospholipid (PL) and triglyceride (TG) fractions in five-year-old children.The STRIP project is a prospective, randomised intervention project in which 1062 seven-month-old infants were recruited from the well-baby clinics. 764 children participated in the 5-year follow-up; 202 of them were randomly selected for this study. Diet was assessed with 4-d dietary records. Serum CE, PL and TG fatty acid compositions were analysed with gas-liquid chromatography.Saturated fat intake of intervention children (mean (confidence interval)) (girls 11.9 (11.2-12.6) % of energy intake (E%); boys 12.5 (11.9-13.1)) was lower than that of the control children (girls 14.4 (13.7-15.2) E%; boys 15.0 (14.3-15. 8) E%) (P=0.0001 for the difference between intervention and control groups). The intake of unsaturated fat differed only slightly. Dietary ratios of polyunsaturated to saturated fatty acids (PS ratios) of the intervention and control diets were 0.44 and 0.33, respectively (P=0.0001). Furthermore, serum cholesterol concentrations of the intervention and control children differed (4. 28 (4.13-4.43) mmol/L vs 4.49 (4.35-4.63) mmol/L; P=0.04). Relative proportion of saturated fatty acids in serum TG was lower (34.9% vs 36.3%; P=0.04) and that of n-6 polyunsaturated fatty acids higher (13.9% vs 12.4%; P=0.0004) in the intervention than in the control children, whereas serum CE and PL fatty acid compositions of intervention and control groups were closely similar. However, intake of linoleic acid correlated better with serum linoleic acid relative content in the CE fraction (r=0.36; P=0.0001) than in the PL (r=0.27; P=0.0002) or in the TG (r=0.23; P=0.0016) fraction.Intervention resulted in decreased intake of saturated fatty acids and lowered serum total and LDL cholesterol concentrations. Of serum lipid fractions, TG fatty acid composition was the most sensitive and parallelled the findings in dietary food records.

At age 5 years, 496 children still living in the city of Turku were available to participate in neurodevelopmental testing.InterventionParticipants were randomly assigned to receive individualized counseling aimed at limiting the child's fat intake to 30% to 35% of daily energy, with a saturated:monounsaturated:polyunsaturated fatty acid ratio of 1:1:1 and a cholesterol intake of less than 200 mg/d (n = 540) or usual health education (control group, n = 522).Main Outcome MeasuresNutrient intake, serum lipid concentrations, and neurological development at 5 years, among children in the intervention vs control groups.ResultsAbsolute and relative intakes of fat, saturated fatty acids, and cholesterol among children in the intervention group were markedly less than the respective values of control children. Mean (SD) percentages of daily energy at age 5 years for the intervention vs control groups were as follows: for total fat, 30.6% (4.5%) vs 33.4% (4.4%) (P
