RESUMO
INTRODUCTION: Lysinuric protein intolerance (LPI), a rare autosomal recessive transport disorder of cationic amino acids lysine, arginine and ornithine, affects intestines, lungs, liver and kidneys. LPI patients may display potentially life-threatening bleeding events, which are poorly understood. AIMS: To characterize alterations in haemostatic and fibrinolytic variables associated with LPI. METHODS: We enrolled 15 adult patients (8 female) and assessed the clinical ISTH/SSC-BAT bleeding score (BS). A variety of metabolic and coagulation assays, including fibrin generation test derivatives, clotting time (CT) and clot lysis time (CLT), thromboelastometry (ROTEM), and PFA-100 and Calibrated Automated Thrombogram (CAT), were used. RESULTS: All patients had mild-to-moderate renal insufficiency, and moderate bleeding tendency (BS 4) without spontaneous bleeds. Mild anaemia and thrombocytopenia occurred. Traditional clotting times were normal, but in contrast, CT in fibrin generation test, and especially ROTEM FIBTEM was abnormal. The patients showed impaired primary haemostasis in PFA, irrespective of normal von Willebrand factor activity, but together with lowered fibrinogen and FXIII. Thrombin generation (TG) was reduced in vitro, according to CAT-derived endogenous thrombin potential, but in vivo TG was enhanced in the form of circulating prothrombin fragment 1 and 2 values. Very high D-dimer and plasmin-α2-antiplasmin (PAP) complex levels coincided with shortened CLT in vitro. CONCLUSIONS: Defective primary haemostasis, coagulopathy, fibrin abnormality (FIBTEM, CT and CLT), low TG in vitro and clearly augmented fibrinolysis (PAP and D-dimer) in vivo were all detected in LPI. Altered fibrin generation and hyperfibrinolysis were associated with the metabolic and renal defect, suggesting a pathogenetic link in LPI.

BACKGROUND: Clinical recommendations to limit gestational weight gain (GWG) imply high GWG is causally related to adverse outcomes in mother or offspring, but GWG is the sum of several inter-related complex phenotypes (maternal fat deposition and vascular expansion, placenta, amniotic fluid and fetal growth). Understanding the genetic contribution to GWG could help clarify the potential effect of its different components on maternal and offspring health. Here we explore the genetic contribution to total, early and late GWG. PARTICIPANTS AND METHODS: A genome-wide association study was used to identify maternal and fetal variants contributing to GWG in up to 10 543 mothers and 16 317 offspring of European origin, with replication in 10 660 mothers and 7561 offspring. Additional analyses determined the proportion of variability in GWG from maternal and fetal common genetic variants and the overlap of established genome-wide significant variants for phenotypes relevant to GWG (for example, maternal body mass index (BMI) and glucose, birth weight). RESULTS: Approximately 20% of the variability in GWG was tagged by common maternal genetic variants, and the fetal genome made a surprisingly minor contribution to explain variation in GWG. Variants near the pregnancy-specific beta-1 glycoprotein 5 (PSG5) gene reached genome-wide significance (P=1.71 × 10-8) for total GWG in the offspring genome, but did not replicate. Some established variants associated with increased BMI, fasting glucose and type 2 diabetes were associated with lower early, and higher later GWG. Maternal variants related to higher systolic blood pressure were related to lower late GWG. Established maternal and fetal birth weight variants were largely unrelated to GWG. CONCLUSIONS: We found a modest contribution of maternal common variants to GWG and some overlap of maternal BMI, glucose and type 2 diabetes variants with GWG. These findings suggest that associations between GWG and later offspring/maternal outcomes may be due to the relationship of maternal BMI and diabetes with GWG.

BACKGROUND: Genetic determinants have an impact on adult weight but the association between genetic determinants and weight at young age is still poorly understood. OBJECTIVE: The objective of this study was to examine the association between genetic risk scores and early growth from birth to 2 years of age. METHODS: Genetic risk scores of 83 adiposity-related or obesity-related single nucleotide polymorphisms (SNPs) (genetic risk score [GRS]83) were calculated for 1278 children. Specific phenotype score for 16 weight-related SNPs (weightGRS) was calculated. Anthropometric data were obtained at birth, 13 months and 2 years of age. RESULTS: The GRS83 was associated with weight at 13 months (ß = 0.080, P = 0.015) and 2 years (ß = 0.080, P = 0.017) of age and with weight gain from birth to 13 months (ß = 0.069, P = 0.036) and to 2 years of age (ß = 0.074, P = 0.028). At 2 years of age, the GRS83 was also associated with weight for height (ß = 0.065, P = 0.046), weight-for-height standard deviation score (SDS) (ß = 0.074, P = 0.022) and body mass index SDS (ß = 0.068, P = 0.045). WeightGRS was associated with higher body weight at 13 months (ß = 0.081, P = 0.014) and 2 years of age (ß = 0.086, P = 0.011). The genetic effect on weight varied from 0.69 to 1.89 kg at 2 years of age according to number of risk alleles. Children with high genetic risk for adiposity were heavier than children with low genetic risk at 2 years of age (12.8 vs. 13.4 kg, P = 0.017). CONCLUSION: The GRS 83 revealed increased genetic risk for higher weight in children already at 13 months and 2 years of age, which may result in increased obesity risk later in life.

OBJECTIVES: The aim was to study the impact of dietary intervention on the properties of paraffin-stimulated saliva, and on dental caries. STUDY DESIGN: At 7 months of age 1062 infants (540 intervention; 522 controls) started in the prospective, randomized Special Turku Intervention Project (STRIP) aimed at restricting the child's saturated fat and cholesterol intake to prevent atherosclerosis of adult age (www.clinicaltrials.gov NCT 00223600). At 3 years of age, every fifth child was invited to an oral sub-study, and 148 (78 boys) children attended. At 6, 9, 12 and 16 years of age 135, 127, 114 and 88 children were restudied, respectively. Dietary intakes of carbohydrates, protein, saturated fat, calcium, phosphate, and fibre were regularly recorded using 4-day food records. Height and weight were regularly monitored. Paraffin-stimulated saliva samples were collected at 6, 9, 12 and 16 years of age, and analyzed for flow rate, buffer capacity, calcium, phosphate and proteins. Dental health was recorded and expressed as d3mft/D3MFT, and as time of caries onset. RESULTS: Dietary intakes of calcium, phosphate and fibre, and salivary flow rate increased with time in both groups (p<0.001, GLM for repeated measures). Fibre intake and salivary flow rate were higher in the intervention than in the control group (p=0.042 and p=0.0394, respectively, GLM for repeated measures). There were no correlations between dietary intakes and salivary concentrations of calcium or phosphate. Children who did not have caries experience (d3mft/D3MFT=0) during the entire follow-up had higher salivary calcium than those who had caries already at 3 years of age. The association between salivary calcium and caries onset was significant up to 12 years of age. Toothbrushing frequency was statistically significantly associated with caries-onset at ages 6 (gamma statistic 0.457, p=0.046) and 12 years (gamma statistic 0.473, p=0.019). CONCLUSIONS: The current long-term dietary intervention increased children's paraffin-stimulated salivary flow rate. The concentration of salivary calcium was directly correlated to dental health. Higher salivary flow rate in the intervention group is believed to be due to higher fibre intake in the intervention group.

OBJECTIVES: We examined how maternal overweight impacts full breastfeeding (BF), total duration of BF and the age of introduction of complementary foods (CFs) and whether these have effect on children's growth from 0 to 2 years. SUBJECTS/METHODS: From 1797 families participating in the STEPS Study, 848 children had data on BF and anthropometric data at 13 months and 2 years of age and were included in this study. Data on BF and CFs were collected using a self-administered follow-up diary. Information regarding maternal weight, height, pregnancy and delivery were received from maternity clinics and the National Longitudinal Census Files. The children's weight and length/height were recorded during the study visits at 13 months and 2 years. RESULTS: Overweight women breastfed fully (2.2 vs 2.8 months, P<0.0001) and totally (7.4 vs 9.0 months, P<0.0001) for a shorter time and introduced CFs earlier (4.1 vs 4.3 months, P=0.02) than normal weight women. Children of overweight women were heavier and had a higher body mass index at 2 years than children of normal weight women. At 2 years of age 30% of boys and 17% of girls were overweight or obese. However, children's obesity risk was not increased by maternal overweight (odds ratio (OR) 1.04, P=0.12). Longer duration of full BF (OR 0.86, P=0.04) and partial BF (OR 0.91, P=0.02) and delayed introduction of CFs (OR 0.69, P=0.03) were protective against obesity. CONCLUSIONS: Our study suggests that women who were overweight or obese before pregnancy breastfed for a shorter time and introduced CFs earlier than normal weight women, which may further impact children's growth.

UNLABELLED: Studies on children's carbohydrate intake, especially fibre intake, and its associations with later health are rare. The current recommendations for fibre intake in children are based on average assumptions and data extrapolated from intakes in adults. Generally, increase in whole-grain consumption and decrease in sucrose intake are considered healthy. Due to fibre's high bulk volume however, excessive dietary fibre has been feared to decrease energy density have effects on growth, at least in developing countries and in children consuming very restricted diets. Furthermore, it has been speculated that if fats are reduced from the diet, it may become high in sucrose. In STRIP study, which is a long-term, randomized controlled trial designed to decrease the exposure of children to known risk factors of atherosclerosis, carbohydrate intakes have been investigated in detail in children aged 13 months to 9 years. The intervention was successful in decreasing saturated fat intake and cholesterol concentrations throughout childhood and adolescence. The study results also show that a higher than average fibre intake does not displace energy or disturb growth in children and that children with high fibre intake have better dietary quality than those with low fibre intake. Dietary fibre intake associated with lower serum total cholesterol concentrations whereas increases in total carbohydrate, sucrose and fructose intakes associated with increases in serum triglyceride concentrations. In conclusion, from the point of view of CHD risk factor prevention, efforts aiming at increasing the fibre intake while restricting that of refined sugar seem justified in the child population in developed countries.

This study investigated salivary cholesterol of children from 6 to 16 years of age in response to dietary intervention. One thousand sixty-two infants started in the prospective, randomized project. At 3 years of age, every fifth child was invited into the study (n=178). Of these, 148 enrolled, and 86 completed the oral sub-study at 16 years of age. The intervention aimed at restricting the child's saturated fat and cholesterol intake. Control children received no special recommendations. Every third year, paraffin-stimulated saliva samples (10.0 mL) were collected for cholesterol assays. Nutrient intakes and serum total cholesterol concentrations were regularly followed up by means of 4-day food records and blood samples. Intake of saturated fatty acids (SAFA) was lower in the intervention than in the control group (p<0.001). Salivary cholesterol concentration increased from 1.9 (±1.1) µmol/L at 6 years of age to 16.0 (±9.0) µmol/L at 16 years of age. The increase was smaller in the intervention than in the control group (p<0.001). The ratios of salivary to serum cholesterol concentrations tended to be higher in boys than in girls (p=0.07). Thus, dietary intervention was reflected in children's salivary cholesterol values more sensitively than in serum cholesterol values. (clinicaltrials.gov NCT00223600).

The 9th Unilever Nutrition Symposium entitled 'Essential fats for future health', held on 26-27 May 2010, aimed to review the dietary recommendations for essential fatty acids (EFA); discuss the scientific evidence for the roles of EFA in cognition, immune function and cardiovascular health; and to identify opportunities for joint efforts by industry, academia, governmental and non-governmental organizations to effectively improve health behaviour. This paper summarizes the main conclusions of the presentations given at the symposium. Linoleic acid (LA) and α-linolenic acid (ALA) are EFA that cannot by synthesized by the human body. Docosahexaenoic acid (DHA) is considered as conditionally essential because of its limited formation from ALA in the human body and its critical role in early normal retinal and brain development and, jointly with eicosapentaenoic acid (EPA), in prevention of cardiovascular disease (CVD). Some evidence for possible beneficial roles of n-3 fatty acids for immune function and adult cognitive function is emerging. A higher consumption of polyunsaturated fatty acids (PUFA; >10%E), including LA, ALA and at least 250-500 mg per day of EPA+DHA, is recommended for prevention of coronary heart disease (CHD). Two dietary interventions suggest that EFA may affect CVD risk factors in children similarly as in adults. To ensure an adequate EFA intake of the population, including children, public health authorities should develop clear messages based on current science; ensure availability of healthy, palatable foods; and collaborate with scientists, the food industry, schools, hospitals, health-care providers and communities to encourage consumers to make healthy choices.

AIM: The aim of this study was to evaluate the impact of individualised dietary and lifestyle counselling, primarily aimed to decrease serum low-density lipoprotein cholesterol, on the clustering of overweight-related cardiometabolic risk factors in children. DESIGN AND PARTICIPANTS: The 7-month-old study children were randomized either to counselling (n = 540) or control group (n = 522). MAIN OUTCOME MEASURES: The 5- to 15-year-old participants who fulfilled the international criteria were classified as overweight. Being in the highest [lowest for high-density lipoprotein (HDL) cholesterol] age- and gender-specific quintile of body mass index (BMI), blood pressure, serum triglycerides, HDL cholesterol or glucose was considered a risk factor. A cluster was defined as having high BMI and > or = 2 other risk factors. RESULTS: The counselling did not reduce the prevalence of overweight in 5- to 15-year-old participants. From age 7 onwards, the proportion of children with > or = 2 risk factors was lower in the intervention than in the control group (p = 0.005). At the age of 15 years, 13.0% of girls and 10.8% of boys in the intervention group and 17.5% of girls and 18.8% of boys in the control group had the risk factor cluster (p = 0.046 for main effect of the study group). Having even one risk factor at the age of 5 years predicted the clustering of risk factors at the age of 15 years (OR: 3.8, p < 0.001). CONCLUSION: Repeated, individualized dietary and lifestyle counselling may reduce the clustering of overweight-related cardiometabolic risk factors in adolescents even though the counselling is not intense enough to prevent overweight.

Lysinuric protein intolerance (LPI) is a rare autosomal recessive disorder characterized by defective transport of cationic amino acids. Poor intestinal absorption and increased renal loss of arginine, ornithine and lysine lead to low plasma concentrations of these amino acids and, subsequently, to impaired urea cycle function. The patients therefore have decreased nitrogen tolerance, which may lead to hyperammonaemia after ingestion of normal amounts of dietary protein. As a protective mechanism, most patients develop strong aversion to protein-rich foods early in life. Oral supplementation with citrulline, which is absorbed normally and metabolized to arginine and ornithine, improves protein tolerance to some extent, as do sodium benzoate and sodium phenylbutyrate also used by some patients. Despite effective prevention of hyperammonaemia, the patients still consume a very restricted diet, which may be deficient in energy, essential amino acids and some vitamins and minerals. To investigate the potential nutritional problems of patients with lysinuric protein intolerance, 77 three- to four-day food records of 28 Finnish LPI patients aged 1.5-61 years were analysed. The data suggest that the patients are clearly at risk for many nutritional deficiencies, which may contribute to their symptoms. Their diet is highly deficient in calcium, vitamin D, iron and zinc. Individualized nutritional supplementation accompanied by regular monitoring of dietary intake is therefore an essential part of the treatment of LPI.

CONTEXT: Recent data indicate a marked increase in the prevalence of obesity among school-aged children. Thus, efficacious programmes that prevent overweight development in children are urgently needed. OBJECTIVE: To evaluate the impact of repeatedly given, individualised dietary and lifestyle counselling on the prevalence of overweight during the first 10 years of life. DESIGN AND PARTICIPANTS: This study was a part of the Special Turku Coronary Risk Factor Intervention Project for Children (STRIP), which is a prospective, randomised trial aimed at reducing the exposure of the intervention children to the known risk factors of atherosclerosis. At the child's age of 7 months, 1062 children were assigned to an intervention group (n=540) or to a control group (n=522). The intervention children received individualised counselling focused on healthy diet and physical activity biannually. Height and weight of the children were measured at least once a year. MAIN OUTCOME MEASURE: Prevalence of overweight and obesity among the intervention and control children by sex and age. Children were classified as overweight or obese if their weight for height was >20% or > or =40% above the mean weight for height of healthy Finnish children, respectively. RESULTS: After the age of 2 years, there were continuously fewer overweight girls in the intervention group than in the control group. At the age of 10 years, 10.2% of the intervention girls and 18.8% of the control girls were overweight (P=0.0439), whereas 11.6% of the intervention boys and 12.1% of the control boys were overweight (P approximately 1.00). Only three children in the intervention group were obese at some age point, whereas 14 control children were classified as obese at some age point. CONCLUSION: Individualised dietary and lifestyle counselling given twice a year since infancy decreases prevalence of overweight in school-aged girls even without any primary energy restrictions.

The dental health of children in western countries has improved without a concomitant decrease in the mean sucrose consumption. Our aim was to analyse the association of long-term sucrose consumption with dental health in children representing the highest (n = 33, 18 boys) and the lowest 5 percentiles (n = 33, 21 boys) of sucrose intake, in a study where food consumption was prospectively recorded from infancy to 10 years of age. The sum of decayed, missing and filled teeth in the primary (dmft) and permanent (DMFT) teeth was assessed. Children's sucrose intake in the high intake group was constantly higher than in their counterparts (p < 0.001), and already exceeded 10% of energy intake (E %) at 2 years of age. The mean +/- SD of the dmft + DMFT scores was higher in the high than in the low sucrose intake group (3.9 +/- 3.9 and 1.9 +/- 2.5, respectively; p = 0.032). We conclude that a persistently high sucrose intake increases the risk of dental caries in children.

OBJECTIVE: To assess the impact of nutrition counselling given to 7.5- to 9-y-old children and their parents on children's nutrition knowledge and nutrient intakes. DESIGN AND SUBJECTS: The study children are participants in a prospective, randomised STRIP study (Special Turku Coronary Risk Factor Intervention Project for Children), whose aim was to decrease the intakes of saturated fat and cholesterol while increasing the intake of unsaturated fat in the intervention children from the age of 7 months onwards. Nutrition counselling was given only to the parents until the child's age of 7 y. Nutrition knowledge and nutrient intakes (total energy, total fat, saturated fat, unsaturated fat and sodium) were studied in a time-restricted cohort of 47, 7-y-old intervention and 51 control children. Thereafter, nutrition counselling was given both to the children and parents. Children's nutrition knowledge and nutrient intakes were measured again at the age of 9 y. RESULTS: Biannual nutrition counselling given to the intervention children and the parents maintained the differences in saturated fatty acid intake attained during the intervention given to the parents alone (11.5 vs 13.3 E% (percent of energy intake), at the age of 7 y, P<0.01; 11.1 vs 13.4 E% at the age of 9 y, respectively; P<0.01). The intervention children used more polyunsaturated fatty acids at the age of 9 y than the control children (5.7 vs 5.1 E%, P=0.05). At 7 y, the intervention and control children had similar nutrition knowledge scores (total knowledge score 12.9 vs 12.0, respectively, P=0.13). After 1.5 y of nutrition intervention, at 9 y, the intervention children's nutrition knowledge was higher than that of the controls (total nutrition score 16.5 vs 13.2, respectively, P<0.001) and the ability to explain the reasons for their picture choices in the nutrition knowledge test had increased. CONCLUSION: This study showed that only a relatively short period of counselling with low input is needed to increase in children's nutrition knowledge and ability to explain nutrition-related subjects if advice has first been given to the parents and if the parents have received reinforcement and concrete help with parent-child communication after their children have been involved in the counselling. The differences attained in nutrient intake could also be maintained.

This review covers two ongoing studies in Finland: the Cardiovascular Risk in Young Finns study, which started in 1978, and the Special Turku Coronary Risk Factor Intervention Project for Children (STRIP), which started in 1989. In the cross-sectional Cardiovascular Risk in Young Finns study, cardiovascular risk factors were first assessed in 1980 in 3596 children and adolescents covering ages between 3 and 18 y at 3-y intervals. The latest follow-up examination was performed in 2001, when risk factors and early markers of atherosclerosis in carotid and brachial arteries were examined in 2264 subjects from the original cohorts, now covering ages from 24 to 39 y. The results clearly show that an individual's coronary heart disease (CHD) risk factor profile is regulated by early lifestyle-related factors and that exposure to risk factors in childhood induces changes in arteries that contribute to the development of atherosclerosis in adulthood. In the STRIP study, 1062 infants were randomized into an intervention group (n = 540; low-saturated-fat, low-cholesterol diet) or a control group (n = 522) at 7 mo of age. Fat, saturated fat and cholesterol intakes have been lower, while the polyunsaturated to saturated fat ratio has been higher in the intervention children than in the control children throughout the ongoing trial. During the first 7 y of life, serum cholesterol concentration was 0.2-0.3 mmol/l lower in the intervention boys than in the control boys, but the difference was negligible in girls. Neurological development of the intervention children at age 5 y was at least as good as that of the control children. Counselling had no effect on children's growth.

Most of the counselling in health care targeted at child nutrition is delivered via the parents, but little is known about the effects of such counselling on the nutrition knowledge and dietary habits of the parents. In the Special Turku Coronary Risk Factor Intervention Project for Children (STRIP), we studied how 6.5 years of child-targeted nutrition counselling affected the knowledge, attitudes and dietary habits of the parent mainly responsible for food purchase and preparation. We used a questionnaire and a 24-h recall interview in a time-restricted cohort of 98 families belonging to the intervention group and 89 families belonging to the control group in the STRIP project. After controlling for background variables, the intervention parents had better knowledge than the control parents of causal relationships between food choices and coronary heart disease and of the nutritional composition of foods. Knowledge of nutrition concepts did not differ between the two groups. The quality of fat was better in the diet of the intervention parents, they consumed less salt and they also had more knowledge concerning these subjects compared to the control parents (higher behavioural capability scores). The behavioural capability scores of the total group correlated poorly with their nutrient intakes. Thus, child-targeted nutrition intervention delivered to the parents increased parental nutrition knowledge and improved the quality of the parents' diet. However, as nutrition knowledge of the parents correlated poorly with their nutrient intakes, other factors than knowledge appear to influence parental dietary decisions.

The present study tested the hypothesis that reduced arterial elasticity seen in hypertension is related to increased oxidation of LDL. Fifteen men with borderline hypertension (BHT), with blood pressure values classified as high normal (systolic blood pressure 130-140 mmHg or diastolic blood pressure 85-89 mmHg) were included. The control group comprised 22 men with normal blood pressure values (<135/80 mmHg) matched for age, body size and LDL-cholesterol level. Distensibility of aorta was measured using magnetic resonance imaging, and distensibility of the common carotid artery using ultrasound. Baseline LDL diene conjugation was used as a marker for ox-LDL. Aortic and carotid distensibilities were lower in the BHT men than in controls (1.4 +/- 0.6 vs. 1.9 +/- 0.6%/10 mmHg, p<0.05 for aortic distensibility; 2.9 +/- 0.9 vs. 3.6 +/- 0.6%/10 mmHg, p<0.05 for carotid distensibility). Ox-LDL was significantly higher in the BHT men than in controls (44 +/-15 vs. 28 +/- 8 micromol/L, p<0.01). In univariate analysis, ox-LDL associated with aortic distensibility (r=-0.43, p<0.05). In multivariate analysis, the differences in distensibilities between the groups disappeared when the values were adjusted for ox-LDL. These data show decreased arterial elasticity and increased LDL oxidation in young men with borderline hypertension, and suggest that oxidative modification of LDL particles may play a pathophysiological role in the development of reduced arterial distensibility in hypertension.

In many very-low-birth-weight (VLBW) infants the ductus arteriosus fails to close spontaneously, and they subsequently develop signs and symptoms of poor tissue perfusion and heart failure. This study evalutes the results of early surgical closure of patent ductus arteriosus (PDA). We retrospectively reviewed the records of all 101 VLBW infants who weighed 1,500 g or less when their PDA was surgically ligated in Turku University Hospital between 1988 and 1998. The mean gestational age at birth was 27.2 weeks and mean birth weight 963+/-239 g. The operation was performed at 12+/-8 days of age; the infants' weight at operation was 969+/-231 g and they were tracheally extubated 11+/-14 days after the operation. The surgery-related mortality was 3% (3/101) and overall mortality 10% (10/101). We conclude that surgical closure of PDA is safe and effective in VLBW infants.

OBJECTIVE: To compare nutrition knowledge and food intake in 7-y-old intervention and control children in an atherosclerosis risk factor intervention trial after 6.5 y of nutrition counselling given to the parents. DESIGN, SUBJECTS AND METHODS: Intervention families in the Special Turku Coronary Risk Factor Intervention Project received child-oriented nutritional counselling one to three times a year since child's age of 7 months, aimed at reduced saturated fat and cholesterol intake. Children's nutrition knowledge was analysed in a time-restricted cohort of 70 seven-y-old (34 boys) intervention children and 70 control children (40 boys) with a picture identification test. For comparison, children's food intake was evaluated using scores developed for the project that reflected quality and quantity of fat and quantity of salt in children's two or three 4-day food diaries recorded between 5.5 and 7 y of age. RESULTS: Child-targeted nutrition counselling of the intervention families only slightly increased intervention children's knowledge of heart-healthy foods (42.6% vs 34.9% correct answers by the intervention and control children, P = 0.057). Only < or = 20% of the children were able to adequately justify their answers in the test. The food diaries of the intervention children comprised more foods low in saturated fat and high in unsaturated fat than those of the control children (57.1% vs 41.7% of the maximum score for low fat foods, P = 0.0001; 48.9% vs 37.7% for high unsaturated fat foods, P = 0.0009, respectively), but the intervention and control children consumed similar amounts of low-salt foods (P = 0.23). Nutrition knowledge and food use scores correlated poorly (r = -0.20-0.35). CONCLUSIONS: Child-targeted nutrition counselling repeatedly given to the parents during and after child's infancy strongly influenced food choice scores of the 5.5-7-y-old children but failed to influence children's salt intake or scores in a nutrition knowledge picture test.

BACKGROUND: Introducing nutritional and lifestyle principles to children in late infancy may permanently improve their adherence to a low-saturated fat, low-cholesterol diet, thus reducing of coronary risk factors, but worries about possible effects on growth and development have hampered such an approach. OBJECTIVE: The Special Turku Coronary Risk Factor Intervention Project for Babies (STRIP) aimed to decrease exposure to known environmental atherosclerosis risk factors in children 7-36 mo of age. DESIGN: Repeated, individualized counseling aimed at promoting a fat intake of 30% of energy and a 1:1:1 ratio of saturated to monounsaturated to polyunsaturated fat intake was provided (n = 540 intervention children; 284 boys). Nutrition was discussed superficially with the families of the control children (n = 522; 266 boys) and food intake was recorded at 3-6-mo intervals by use of 3-4-d food diaries. Serum lipids were measured at 6-12-mo intervals and growth was monitored regularly. RESULTS: Fat intake of the intervention (control) children provided 29.5% (29.4%) of energy at the age of 8 mo, 26.6% (28.5%) of energy at 13 mo, 30.5% (33.5%) of energy at 24 mo, and 31. 5% (33.5%) of energy at 36 mo. The intervention children consistently consumed less saturated fat than did the control children (P: <0.0001). Recommended intakes of other nutrients (except vitamin D and occasionally iron) were reached irrespective of the amount and type of dietary fat. Serum cholesterol, non-HDL cholesterol, and HDL-cholesterol concentrations were 3-6% lower in the intervention children than in the control children. The intervention had no effect on height, weight, or head circumference gain. Fat intake did not predict children's growth patterns. CONCLUSION: Repeated, individualized counseling in early childhood aimed at reducing consumption of saturated fat and cholesterol was effective and feasible and did not restrict growth in circumstances in which children were regularly monitored.
