Abstract
Introduction Background: infants receiving full breastfeeding (FBF) regulate their appetites differently from those receiving human milk substitutes (HMS). In addition, early exposure to the dietary cholesterol in human milk could lead to better cholesterol regulation in later stages of life. Therefore, the purpose was to compare lipid profiles in 4-month-old infants and to correlate lipid profile with anthropometric indicators and appetite-regulating hormones according to the type of feeding. Methods: this was a cross-sectional and correlational study, which included 145 mother-infant dyads according to the type of feeding; 64 received FBF, 47 partial breastfeeding (PBF), and 34 HMS. The complete lipid profile, total ghrelin, leptin, peptide YY, and glucagon-like peptide type 1 were measured. Z-scores for weight/age, length/age, weight/length, triceps (TSF) and subscapular folds (SSF) and body mass index for age were also obtained. Results: there were significant differences in triglycerides and LDL cholesterol according to the type of feeding. In the HMS group, an inverse relationship was observed between ghrelin and triglycerides (p = 0.038), ghrelin and total cholesterol (TC) (p = 0.026), and peptide YY and HDL cholesterol (p = 0.017). In the PBF group, a direct relationship was observed between length/age (z) and triglycerides (p = 0.001) and between subscapular folds and TC (p = 0.049). In infants receiving HMS, a direct correlation was observed between weight/age (z) and TC (p = 0.045) and between length/age (z) and LDL cholesterol (p = 0.010). Conclusion: these findings show a relationship between growth, energy reserve, lipid profile, and modulation of appetite-regulating hormones according to the type of feeding they received.

Abstract
Cardiovascular diseases (CVD) may be manifested from a very early age. Genetic and environmental (epigenetic) factors interact to affect development and give rise to an abnormal phenotypical expression of genetic information, although not eliciting changes in the nucleotide sequence of DNA. It has been scientifically proven that increased oxidative stress (OS) caused by disease (overweight, obesity, diabetes), nutritional imbalances, unhealthy lifestyles (smoking, alcohol, substance abuse) in the mother during pregnancy may induce placental dysfunction, intrauterine growth restriction, prematurity, low birth weight, postnatal adiposity rebound, metabolic alterations and consequent onset of traditional cardiovascular risk factors. OS represents the cornerstone in the onset of atherosclerosis and manifestation of CVD following an extended asymptomatic period. OS activates platelets and monocytes eliciting the release of pro-inflammatory, pro-atherogenic and pro-oxidising substances resulting in endothelial dysfunction, decrease in flow-mediated arterial dilatation and increase in carotid intima-media thickness. The prevention of CVD is defined as primordial (aimed at preventing risk factors development), primary (aimed at early identification and treatment of risk factors), secondary (aimed at reducing risk of future events in patients who have already manifested a cardiovascular event), and tertiary (aimed at limiting the complex outcome of disease). Atherosclerosis prevention should be implemented as early as possible. Appropriate screening should be carried out to identify children at high risk who are apparently healthy and implement measures including dietary and lifestyle changes, addition of nutritional supplements and, lastly, pharmacological treatment if risk profiles fail to normalise. Reinstating endothelial function during the reversible stage of atherosclerosis is crucial.

Abstract
Cholesterol is one of the functional nutrients in human milk, which is indispensable for infant growth. In this study, the concentration of cholesterol and desmosterol in human milk from four Asian countries (n = 578), including Korea, China, Vietnam, and Pakistan, were investigated. The average cholesterol concentrations of Korea and China were similar ranging between 90.2-91.6 mg/L, but those from Vietnam and Pakistan were higher at 113.8 and 175.7 mg/L, respectively. The relative standard deviations were 31-36%, except for Pakistan (51%), showing a broad distribution of 48 to 612 mg/L. Desmosterol concentrations were similar, ranging between 11.2 and 12.8 mg/L except for Pakistan, which was lower than other countries at 9.4 mg/L. In addition, the cholesterol and desmosterol concentrations during the lactation periods were not significantly different in all four Asian countries. Mothers' BMI did not significantly impact the cholesterol and desmosterol concentration in maternal milk within the same country.

Nutr Res Pract 2020; 15:367-381. [PMID: 34093977 PMCID: PMC8155227 DOI: 10.4162/nrp.2021.15.3.367] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2020] [Revised: 07/02/2020] [Accepted: 08/25/2020] [Indexed: 01/04/2023] Open
Abstract
BACKGROUND/OBJECTIVES This study aimed to establish a mother and child cohort in the Chinese population, and investigate human breastmilk (HBM) composition and its relationship with maternal body mass index (BMI) and infant growth during the first 3 mon of life. SUBJECTS/METHODS A total of 101 Chinese mother and infant pairs were included in this prospective cohort. Alterations in the milk macronutrients of Chinese mothers at 1 mon (T1), 2 mon (T2), and 3 mon (T3) lactation were analyzed. HBM fatty acid (FA) profiles were measured by gas chromatography (GC), and HBM proteomic profiling was achieved by matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry (MS). RESULTS During the first 3 mon of lactation (P < 0.05), significant decreases were determined in the levels of total energy, fat, protein, and osteopontin (OPN), as well as ratios of long-chain saturated FA (including C16:0, C22:0 and C24:0), monounsaturated FA (including C16:1), and n-6 poly unsaturated FA (PUFA) (including C20:3n-6 and C20:4n-6, and n-6/n-3). Conversely, butyrate, C6:0 and n-3 PUFA C18:3n-3 (α-linolenic acid, ALA) were significantly increased during the first 3 mon (P < 0.05). HBM proteomic analyses distinguished compositional protein differences over time (P = 0.001). Personalized mother-infant analyses demonstrated that HBM from high BMI mothers presented increased total energy, fat, protein and OPN, and increased content of n-6 PUFA (including C18:3n-6, C20:3n-6 and n-6/n-3 ratio) as compared with low BMI mothers (P < 0.05). Furthermore, BMI of the mothers positively correlated with the head circumference (HC) of infants as well as the specific n-6 PUFA C20:3n-6 over the 3 time points examined. Infant HC was negatively associated with C18:0. CONCLUSION This study provides additional evidence to the Chinese HBM database, and further knowledge of FA function. It also helps to establish future maternal strategies that support the healthy growth and development of Chinese infants.

Abstract
Maternal lifestyle during pregnancy, as well as early nutrition and the environment infants are raised in, are considered relevant factors for the prevention of childhood obesity. Several models are available for the prediction of childhood overweight and obesity, yet most have not been externally validated. Moreover, the factors considered in the models differ among studies as the outcomes manifest after birth and depend on maturation processes that vary between individuals. The current Review examines and interprets data on the early determinants of childhood obesity to provide relevant strategies for daily clinical work. We evaluate a selection of prenatal and postnatal factors associated with child adiposity. Actions to be considered for preventing childhood obesity include the promotion of healthy maternal nutrition and weight status at reproductive age and during pregnancy, as well as careful monitoring of infant growth to detect early excessive weight gain. Paediatricians and other health-care professionals should provide scientifically validated, individual nutritional advice to families to counteract excessive adiposity in children. Based on systematic reviews, original papers and scientific reports, we provide information to help with setting up public health strategies to prevent overweight and obesity in childhood.

Abstract
BACKGROUND As part of efforts to prevent childhood overweight and obesity, we need to understand the relationship between total fat intake and body fatness in generally healthy children. OBJECTIVES To assess the effects and associations of total fat intake on measures of weight and body fatness in children and young people not aiming to lose weight. SEARCH METHODS For this update we revised the previous search strategy and ran it over all years in the Cochrane Library, MEDLINE (Ovid), MEDLINE (PubMed), and Embase (Ovid) (current to 23 May 2017). No language and publication status limits were applied. We searched the World Health Organization International Clinical Trials Registry Platform and ClinicalTrials.gov for ongoing and unpublished studies (5 June 2017). SELECTION CRITERIA We included randomised controlled trials (RCTs) in children aged 24 months to 18 years, with or without risk factors for cardiovascular disease, randomised to a lower fat (30% or less of total energy (TE)) versus usual or moderate-fat diet (greater than 30%TE), without the intention to reduce weight, and assessed a measure of weight or body fatness after at least six months. We included prospective cohort studies if they related baseline total fat intake to weight or body fatness at least 12 months later. DATA COLLECTION AND ANALYSIS We extracted data on participants, interventions or exposures, controls and outcomes, and trial or cohort quality characteristics, as well as data on potential effect modifiers, and assessed risk of bias for all included studies. We extracted body weight and blood lipid levels outcomes at six months, six to 12 months, one to two years, two to five years and more than five years for RCTs; and for cohort studies, at baseline to one year, one to two years, two to five years, five to 10 years and more than 10 years. We planned to perform random-effects meta-analyses with relevant subgrouping, and sensitivity and funnel plot analyses where data allowed. MAIN RESULTS We included 24 studies comprising three parallel-group RCTs (n = 1054 randomised) and 21 prospective analytical cohort studies (about 25,059 children completed). Twenty-three studies were conducted in high-income countries. No meta-analyses were possible, since only one RCT reported the same outcome at each time point range for all outcomes, and cohort studies were too heterogeneous to combine.Effects of dietary counselling to reduce total fat intake from RCTsTwo studies recruited children aged between 4 and 11 years and a third recruited children aged 12 to 13 years. Interventions were combinations of individual and group counselling, and education sessions in clinics, schools and homes, delivered by dieticians, nutritionists, behaviourists or trained, supervised teachers. Concerns about imprecision and poor reporting limited our confidence in our findings. In addition, the inclusion of hypercholesteraemic children in two trials raised concerns about applicability.One study of dietary counselling to lower total fat intake found that the intervention may make little or no difference to weight compared with usual diet at 12 months (mean difference (MD) -0.50 kg, 95% confidence interval (CI) -1.78 to 0.78; n = 620; low-quality evidence) and at three years (MD -0.60 kg, 95% CI -2.39 to 1.19; n = 612; low-quality evidence). Education delivered as a classroom curriculum probably decreased BMI in children at 17 months (MD -1.5 kg/m2, 95% CI -2.45 to -0.55; 1 RCT; n = 191; moderate-quality evidence). The effects were smaller at longer term follow-up (five years: MD 0 kg/m2, 95% CI -0.63 to 0.63; n = 541; seven years; MD -0.10 kg/m2, 95% CI -0.75 to 0.55; n = 576; low-quality evidence).Dietary counselling probably slightly reduced total cholesterol at 12 months compared to controls (MD -0.15 mmol/L, 95% CI -0.24 to -0.06; 1 RCT; n = 618; moderate-quality evidence), but may make little or no difference over longer time periods. Dietary counselling probably slightly decreased low-density lipoprotein (LDL) cholesterol at 12 months (MD -0.12 mmol/L, 95% CI -0.20 to -0.04; 1 RCT; n = 618, moderate-quality evidence) and at five years (MD -0.09, 95% CI -0.17 to -0.01; 1 RCT; n = 623; moderate-quality evidence), compared to controls. Dietary counselling probably made little or no difference to HDL-C at 12 months (MD -0.03 mmol/L, 95% CI -0.08 to 0.02; 1 RCT; n = 618; moderate-quality evidence), and at five years (MD -0.01 mmol/L, 95% CI -0.06 to 0.04; 1 RCT; n = 522; moderate-quality evidence). Likewise, counselling probably made little or no difference to triglycerides in children at 12 months (MD -0.01 mmol/L, 95% CI -0.08 to 0.06; 1 RCT; n = 618; moderate-quality evidence). Lower versus usual or modified fat intake may make little or no difference to height at seven years (MD -0.60 cm, 95% CI -2.06 to 0.86; 1 RCT; n = 577; low-quality evidence).Associations between total fat intake, weight and body fatness from cohort studiesOver half the cohort analyses that reported on primary outcomes suggested that as total fat intake increases, body fatness measures may move in the same direction. However, heterogeneous methods and reporting across cohort studies, and predominantly very low-quality evidence, made it difficult to draw firm conclusions and true relationships may be substantially different. AUTHORS' CONCLUSIONS We were unable to reach firm conclusions. Limited evidence from three trials that randomised children to dietary counselling or education to lower total fat intake (30% or less TE) versus usual or modified fat intake, but with no intention to reduce weight, showed small reductions in body mass index, total- and LDL-cholesterol at some time points with lower fat intake compared to controls. There were no consistent effects on weight, high-density lipoprotein (HDL) cholesterol or height. Associations in cohort studies that related total fat intake to later measures of body fatness in children were inconsistent and the quality of this evidence was mostly very low. Most studies were conducted in high-income countries, and may not be applicable in low- and middle-income settings. High-quality, longer-term studies are needed, that include low- and middle-income settings to look at both possible benefits and harms.

We included prospective analytical cohort studies in these children if they related baseline total fat intake to weight or body fatness at least 12 months later. We duplicated inclusion decisions and resolved disagreement by discussion with other authors. DATA COLLECTION AND ANALYSIS We extracted data on participants, interventions or exposures, controls and outcomes, and trial or cohort quality characteristics, as well as data on potential effect modifiers, and assessed risk of bias for all included studies. We extracted outcome data using the following time point ranges, when available: RCTs: baseline to six months, six to 12 months, one to two years, two to five years and more than five years; cohort studies: baseline to one year, one to two years, two to five years, five to 10 years and more than 10 years.

In addition, the inclusion of hypercholesteraemic children in two trials raised concerns about applicability. Lower versus usual or modified total fat intake may have made little or no difference to weight over a six- to twelve month period (mean difference (MD) -0.50 kg, 95% confidence interval (CI) -1.78 to 0.78; 1 RCT; n = 620; low-quality evidence), nor a two- to five-year period (MD -0.60 kg, 95% CI -2.39 to 1.19; 1 RCT; n = 612; low-quality evidence). Compared to controls, lower total fat intake (30% or less TE) probably decreased BMI in children over a one- to two-year period (MD -1.5 kg/m2, 95% CI -2.45 to -0.55; 1 RCT; n = 191; moderate-quality evidence), with no other differences evident across the other time points (two to five years: MD 0.00 kg/m2, 95% CI -0.63 to 0.63; 1 RCT; n = 541; greater than five years; MD -0.10 kg/m2, 95% CI -0.75 to 0.55; 1 RCT; n = 576; low-quality evidence). Lower fat intake probably slightly reduced total cholesterol over six to 12 months compared to controls (MD -0.15 mmol/L, 95% CI -0.24 to -0.06; 1 RCT; n = 618; moderate-quality evidence), but may make little or no difference over longer time periods.

However, lower total fat intake probably made little or no difference to HDL-C over a six- to 12-month period (MD -0.03 mmol/L, 95% CI -0.08 to 0.02; 1 RCT; n = 618; moderate-quality evidence), nor a two- to five-year period (MD -0.01 mmol/L, 95% CI -0.06 to 0.04; 1 RCT; n = 522; moderate-quality evidence). Likewise, lower total fat intake probably made little or no difference to triglycerides in children over a six- to 12-month period (MD -0.01 mmol/L, 95% CI -0.08 to 0.06; 1 RCT; n = 618; moderate-quality evidence). Lower versus usual or modified fat intake may make little or no difference to height over more than five years (MD -0.60 cm, 95% CI -2.06 to 0.86; 1 RCT; n = 577; low-quality evidence).Over half the cohort analyses that reported on primary outcomes suggested that as total fat intake increases, body fatness measures may move in the same direction. However, heterogeneous methods and reporting across cohort studies, and predominantly very low-quality evidence, made it difficult to draw firm conclusions and true relationships may be substantially different. AUTHORS' CONCLUSIONS We were unable to reach firm conclusions. Limited evidence from three trials that randomised children to a lower total fat intake (30% or less TE) versus usual or modified fat intake, but with no intention to reduce weight, showed small reductions in body mass index, total- and LDL-cholesterol at some time points with lower fat intake compared to controls, and no consistent differences in effects on weight, high-density lipoprotein (HDL) cholesterol or height. Associations in cohort studies that related total fat intake to later measures of body fatness in children were inconsistent and the quality of this evidence was mostly very low. Twenty-three out of 24 included studies were conducted in high-income countries, and may not be applicable in low- and middle-income settings. High-quality, longer-term studies are needed, that include low- and middle-income settings and look at both possible benefits and risks.

Abstract
BACKGROUND The long chain polyunsaturated fatty acids (LCPUFA) docosahexaenoic acid (DHA) and arachidonic acid (AA) are considered essential for maturation of the developing brain, retina and other organs in newborn infants. Standard infant milk formulae are not supplemented with LCPUFA; they contain only alpha-linolenic acid and linoleic acid, from which formula-fed infants must synthesise their own DHA and AA, respectively. Over the past few years, some manufacturers have added LCPUFA to formula milk and have marketed these products as providing an advantage for the overall development of full-term infants. OBJECTIVES To assess whether supplementation of formula milk with LCPUFA is both safe and beneficial for full-term infants, while focusing on effects on visual function, neurodevelopment and physical growth. SEARCH METHODS Two review authors independently searched the Cochrane Central Register of Controlled Trials (CENTRAL; December 2016), MEDLINE (Ovid, 1966 to December 2016), Embase (Ovid, 1980 to December 2016), the Cumulative Index to Nursing and Allied Health Literature (CINAHL; 1980 to December 2016) and abstracts of the Pediatric Academic Societies (2000 to 2016). We applied no language restrictions. SELECTION CRITERIA We reviewed all randomised controlled trials (RCTs) evaluating effects of LCPUFA supplemented versus non-supplemented formula milk on visual function, neurodevelopment and physical growth. We did not include trials reporting only biochemical outcomes. DATA COLLECTION AND ANALYSIS Two review authors extracted data independently. We assessed risk of bias of included studies using the guidelines of the Cochrane Neonatal Review Group. When appropriate, we conducted meta-analysis to determine a pooled estimate of effect. MAIN RESULTS We identified 31 RCTs and included 15 of these in the review (N = 1889).Nine studies assessed visual acuity, six of which used visual evoked potentials (VEP), two Teller cards and one both. Four studies reported beneficial effects, and the remaining five did not. Meta-analysis of three RCTs showed significant benefit for sweep VEP acuity at 12 months (log of the minimum angle of resolution (logMAR)) (mean difference (MD) -0.15, 95% confidence interval (CI) -0.17 to -0.13; I2 = 0; three trials; N = 244), but meta-analysis of three other RCTs showed no benefit for visual acuity measured with Teller cards at 12 months (cycles/degree) (MD -0.01, 95% CI -0.12 to 0.11; I2 = 0; three trials; N = 256). GRADE analysis for the outcome of visual acuity indicated that the overall quality of evidence was low.Eleven studies measured neurodevelopmental outcomes at or before two years. Nine studies used Bayley Scales of Infant Development, version II (BSID-II), and only two of these studies reported beneficial effects. Meta-analysis revealed no significant differences between LCPUFA and placebo groups in BSID Mental Developmental Index (MDI) scores at 18 months (MD 0.06, 95% CI -2.01 to 2.14; I2 = 75%; four trials; N = 661) and no significant differences in BSID Psychomotor Development Index (PDI) scores at 18 months (MD 0.69, 95% CI -0.78 to 2.16; I2 = 61%; four trials; N = 661). Results showed no significant differences between the two groups in BSID-II scores at one year and two years of age. One study reported better novelty preference measured by the Fagan Infant Test at nine months. Another study reported better problem solving at 10 months. One study used the Brunet and Lezine test to assess the developmental quotient and found no beneficial effects. Follow-up of some infants in different studies at three, six and nine years of age revealed no beneficial effects of supplementation. GRADE analysis of these outcomes indicated that the overall quality of evidence was low.Thirteen studies measured physical growth; none found beneficial or harmful effects of supplementation. Meta-analysis of five RCTs showed that the supplemented group had lower weight (z scores) at one year of age (MD -0.23, 95% CI -0.40 to -0.06; I2 = 83%; N = 521) and that the two groups showed no significant differences with respect to length and head circumference (z scores). Meta-analysis at 18 months and at two years revealed no significant differences between the two groups with respect to weight (kg), length (cm) and head circumference (cm). GRADE analysis of these outcomes indicated that the overall quality of evidence was low. AUTHORS' CONCLUSIONS Most of the included RCTs reported no beneficial effects or harms of LCPUFA supplementation on neurodevelopmental outcomes of formula-fed full-term infants and no consistent beneficial effects on visual acuity. Routine supplementation of full-term infant milk formula with LCPUFA cannot be recommended at this time.

Breast milk composition and infant nutrient intakes during the first 12 months of life. Eur J Clin Nutr 2015; 70:250-6. [PMID: 26419197 DOI: 10.1038/ejcn.2015.162] [Citation(s) in RCA: 131] [Impact Index Per Article: 14.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2015] [Revised: 07/20/2015] [Accepted: 07/23/2015] [Indexed: 01/12/2023]
Abstract
BACKGROUND/OBJECTIVES The objective of this study was to quantify human milk supply and intake of breastfed infants up to age 12 months. In addition, human milk composition was quantified per energetic macronutrient and fatty-acid composition in a subsample of lactating mothers. SUBJECTS/METHODS One hundred and seventy-four Italian breastfed children were followed using test-weighing and 3-day food protocols from birth to age 12 months. From a subsample of 30 mothers breast milk samples were collected at child ages one (T1), two (T2), three (T3) and six (T6) months, and were analyzed for the amount of protein, digestible carbohydrates, total lipids and fatty-acid composition. RESULTS One hundred and forty-two (82%) filled in at least one 3-day food protocol within the first 12 months of life and complied with test-weighing of all milk feeds. The number of valid food protocols declined from 126 infants at 1 month to 77 at 12 months of age. Only galactose, non-protein nitrogen and protein decreased significantly from age 1 to age 6 months of lactation. Maternal body mass index and age affected fatty-acid levels in human milk. Median human milk intake decreased from 625 ml at T1, over 724 ml at T3 to 477 ml/day at T6. Average energy and %energy from protein intake per day increased from 419 kcal (s.d. 99) and 8.4% (1.0) at T1, respectively, to 860 kcal (145) and 16.1% (2.6) at T12. CONCLUSIONS These data provide a reference range of nutrient intakes in breastfed infants and may provide guidance for defining optimal nutrient intakes for infants that cannot be fully breastfed.

Abstract
OBJECTIVE To compare the lipid profile of exclusively breastfed and mixed-fed, term, appropriate for gestation age infants from 6 mo to 1 y of age. METHODS This prospective comparative study included one hundred ninety nine consecutive term healthy infants; 105 on exclusive breastfeeding (EBF) and 94 receiving mixed feeding (MF). These children were recruited at 6 mo of age and followed till 1 y of age. Serum lipid levels of babies were determined at recruitment (6 mo), 9 mo and 1 y of age. Statistical analysis was carried out using SPSS software. RESULTS The mean total cholesterol (TC) at 6 mo in exclusively breastfed group (156.38 ± 50.42 mg/dl) was significantly higher than mixed fed group (139.5 ± 37.59 mg/dl). At 9 mo, high density lipoprotein cholesterol (HDL-C) and triglycerides (TG) levels were significantly different in EBF group than MF group. The lipid profile of both group of babies was comparable at 1 y of age. The HDL-C: LDL-C ratio was significantly different between the two groups (higher in breastfed group) at 1 y. CONCLUSIONS The present study highlights differential lipid profile of exclusively breastfed infants and mixed fed infants.

Abstract
BACKGROUND Lipoprotein subfractions in infants may predict the risk of cardiovascular disease factors in children. OBJECTIVE To examine the relationships between lipid and nonlipid factors and lipoprotein subfractions in infants at birth and follow-up (FU) and in their parents. METHODS Prospective study in a community-based hospital of 103 families ascertained through a pregnant mother at 36 weeks gestation or older. Of 103 infants studied at birth, 85 were sampled at FU at 2-3 months of age, along with 76 fathers. Lipids, lipoproteins, and their subclasses were determined by nuclear magnetic resonance spectroscopy. Correlations of lipid-related parameters were calculated using Spearman rank correlations. RESULTS Female gender in infants and use of formula only were the only nonlipid variables associated with lipoprotein subfractions. LDL parameters were significantly correlated between infants at birth and FU. The largest high-density lipoprotein subfraction, H5C, was the only lipid variable significantly associated between mothers and infants at birth. Paternal low-density lipoprotein size was significantly correlated with that of infants at FU but not at birth. In each of the four groups, markedly inverse interrelationships were found between H5C and small LDL particles. At birth and at FU, apoC-I was strongly related with H5C but not TG. Conversely, apoC-I in the parents was strongly related with TG but not H5C. CONCLUSION Significant relationships were found between lipoprotein subfractions within infants at birth and FU and their parents. ApoC-I and H5C levels very early in life may affect the development of dyslipidemia and obesity in childhood.

Abstract
The aim of this review is to evaluate the effects of omega-3 long chain polyunsaturated fatty acids (n-3 LCPUFA) supplementation in pregnant and lactating women and infants during postnatal life, on the visual acuity, psychomotor development, mental performance and growth of infants and children. Eighteen publications (11 sets of randomized control clinical trial [RCTs]) assessed the effects of the n-3 LCPUFA supplementation duringpregnancyon neurodevelopment and growth, in the same subjects at different time points; 4 publications (2 data sets from RCTs) addressed physiological responses to n-3 LCPUFA supplementation duringpregnancy & lactationand 5 publications (3 data sets from RCTs) exclusively duringlactation. Some of these studies showed beneficial effects of docosahexaenoic acid (DHA) supplementation during pregnancy and/or lactation especially on visual acuity outcomes and some on long-term neurodevelopment; a few, showed positive effects on growth. There were also 15 RCTs involving term infants who received infant formula supplemented with DHA, which met our selection criteria. Many of these studies claimed a beneficial effect of such supplementation on visual, neural, or developmental outcomes and no effects on growth. Although new well designed and conducted studies are being published, evidence from RCTs does not demonstrate still a clear and consistent benefit of n-3 LCPUFA supplementation during pregnancy and/or lactation on term infants growth, neurodevelopment and visual acuity. These results should be interpreted with caution due to methodological limitations of the included studies.

Abstract
A 20-d-old boy was referred to our department because of hyperthyrotropinemia at neonatal mass screening and
diagnosed with neonatal transient hyperthyrotropinemia. A follow-up examination when the patient was 5 mo old
revealed severe hypercholesterolemia. Familial hypercholesterolemia was first suspected because of the
patient’s significantly high levels of total and low-density lipoprotein cholesterol. The parent’s serum lipid
profiles were examined and found to be normal. He was completely breast-fed until 6 mo of age. Breast milk was
still the main source of food for a period following weaning. At 14 mo old, the patient was weaned completely
from breast milk, and his serum cholesterol levels decreased dramatically. According to the normal lipid
profiles of the patient’s parents and the spontaneous normalization of serum cholesterol levels after complete
weaning from breast milk, breast-feeding was suggested to be responsible for his transient severe
hypercholesterolemia. It is well documented that breast-fed infants have higher serum cholesterol levels than
formula-fed infants. However, there is no reported case with severe hypercholesterolemia equivalent to or
higher than the levels observed in the case of familial hypercholesterolemia. Although the exact mechanism is
unknown, it is necessary to consider that a small number of cases develop severe hypercholesterolemia related
to breast-feeding.

Abstract
This paper considers the body of observational evidence examining the association of being breast-fed to cardiovascular risk factors and outcomes in later life, and whether any potentially advantageous findings are causal. Early cardiovascular consequences/correlates of breast-feeding, compared to being formula fed, include markedly higher levels of total blood cholesterol, lower levels of pre-prandial blood glucose and insulin and lower levels of adiposity. However, a key issue is whether these early differences at a period of rapid development programme/influence cardiovascular risk factors and outcomes in later life. Evidence of long-term effects of early feeding, largely from observational studies, has shown that those breast-fed have lower levels of blood total cholesterol, lower risk of type-2 diabetes and marginally lower levels of adiposity and blood pressure in adult life. There is no strong evidence to suggest effects of early feeding on adult levels of blood glucose, blood insulin and CHD outcomes, although further data are needed. However, the influence of confounding factors, such as maternal body size, maternal smoking and socio-demographic factors, and exclusivity of early feeding on these potentially beneficial associations needs to be considered before inferring any causal effects. Moreover, fewer studies have examined whether duration of exclusive breast-feeding has a graded influence on these risk factors and outcomes; such data would help further in deciding upon causal associations. While strong observational evidence suggests nutritional programming of adult cholesterol levels, associations with other markers of cardiometabolic risk and their consequences in later life need to be confirmed in well-conducted observational and experimental studies.

Abstract
OBJECTIVES To compare the lipid profiles of exclusively breastfed and mixed-fed term healthy infants in the first 6 months of life. DESIGN Prospective comparative study. SETTING Study was carried out in a tertiary care hospital. SUBJECTS Four hundred consecutive term healthy infants, 200 on exclusive breastfeeding (group 1) and 200 receiving mixed feeding (group 2) were recruited at 14 weeks of age. At 6 months, 149 and 150 mother-infant pairs were followed up in groups 1 and 2, respectively. METHODS Anthropometric measures of the mother and baby were recorded. Serum lipid levels of the mother and babies were determined at 14 weeks. Babies were followed up till 6 months and their lipid levels were determined again at 6 months. Statistical analysis was carried out using SPSS. RESULTS Two groups were comparable in birth weight and maternal characteristics (P>0.05). Weight and head circumference were significantly more in the breastfed group at 14 weeks as well as at 6 months (P<0.001). Mean total cholesterol (TC) was 205.27+/-47.31 and 176.55+/-32.01 mg/dl in groups 1 and 2, respectively at 14 weeks (CI=20.77-36.66, P<0.001). At 6 months TC was 192.79+/-40.52 and 161.05+/-22.53 mg/dl in the two groups (CI=24.26-39.22, P<0.001). Change in total cholesterol from 14 weeks to 6 months was also significant in both groups (P<0.001). Low-density lipoprotein cholesterol (LDL-C) and triglycerides were significantly higher in the breastfed groups at 14 weeks and 6 months. The high-density lipoprotein cholesterol (HDL-C)/LDL-C significantly improved at 6 months in exclusively breastfed group (P=0.045). A positive correlation was found only at 14 weeks between mother's TC and baby's TC (r=0.332), mother's LDL-C with baby's LDL-C (r=0.223) in mixed fed group. CONCLUSION Breastfed babies have significantly higher TC and LDL-C compared to mixed fed babies in the first 6 months of life with improving HDL-C/LDL-C ratio at 6 months. SPONSORSHIP None.

Abstract
BACKGROUND The n-3 and n-6 fatty acids linolenic acid and linoleic acid are precursors of the n-3 and n-6 long chain fatty acids (LCPUFA). Infant formula has historically only contained the precursor fatty acids. Controversy exists over whether LCPUFA are also essential nutrients in infancy. Over the last few years, some manufacturers have added LCPUFA to formulae and marketed them as providing an advantage for the development of term infants. OBJECTIVES To assess whether supplementation of formula with LCPUFA is safe and of benefit to term infants. SEARCH STRATEGY Eligible studies were identified by searching MEDLINE (March 2007), EMBASE 1980 - 2007, Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, Issue 1, 2007) and CINAHL (December 1982 - March 2007). Abstracts of the Society for Pediatric Research were hand searched from 1980 to 2006 inclusive. Reference lists of published narrative and systematic reviews were also reviewed. No language restrictions were applied. SELECTION CRITERIA All randomised and quasi randomised trials comparing LCPUFA supplemented formula milk vs. non-supplemented formula milk and with clinical endpoints were reviewed. DATA COLLECTION AND ANALYSIS Methodological quality of eligible studies was assessed according to allocation concealment, blinding of intervention, blinding of outcome assessment and completeness of follow up. Data were sought regarding effects on visual acuity, neurodevelopmental outcomes and physical growth. When appropriate, meta-analysis was conducted to provide a pooled estimate of effect. Continuous data were analysed using weighted mean difference (WMD). There were no categorical outcomes in this review. MAIN RESULTS Twenty randomised studies were identified. Fourteen were included (n = 1719) and six excluded. Eleven included studies were of good quality. The main outcomes assessed were visual acuity, neurodevelopmental and physical growth. Visual acuity was measured at various stages throughout the first three years of life by nine studies. Visual evoked potential was used to assess visual acuity in five studies. The remaining four used Teller visual acuity cards. The results were inconsistent. Three studies reported beneficial effect of LCPUFA supplementation on visual acuity while the remaining six did not. Neurodevelopmental outcome was measured at different ages throughout the first two years by eleven studies. Bayley scales of infant development (BSID) was used in eight studies. Only one showed beneficial effect of LCPUFA supplementation on BSID scales. Pooled meta-analysis of the data also did not show any statistically significant benefit of LCPUFA supplementation on either mental or psychomotor developmental index of BSID. One study reported better novelty preference measured by Fagan Infant test at nine months in supplemented infants compared with controls. Another study reported better problem solving at 10 months with supplementation. One study used Brunet and Lezine developmental test to assess the developmental quotient and did not find beneficial effects of LCPUFA supplementation. Physical growth was measured at various ages throughout first three years of life by twelve studies. Some studies reported the actual measurements while some reported the rate of growth over a time period. Some studies z scores. Irrespective of the type of LCPUFA supplementation, duration of supplementation and method of assessment, none of the individual studies found beneficial or harmful effects of LCPUFA supplementation. Meta-analysis of relevant studies also did not show any effect of LCPUFA supplementation on growth of term infants. AUTHORS' CONCLUSIONS The results of most of the well conducted RCTS have not shown beneficial effects of LCPUFA supplementation of formula milk on the physical, visual and neurodevelopmental outcomes of infants born at term. Only one group of researchers have shown some beneficial effects on VEP acuity. Two groups of researchers have shown some beneficial effect on mental development. Routine supplementation of milk formula with LCPUFA to improve the physical, neurodevelopmental or visual outcomes of infants born at term can not be recommended based on the current evidence. Further research is needed to see if the beneficial effects demonstrated by Dallas 2005 trial of Birch et al can be replicated in different settings.

Abstract
BACKGROUND Evidence from observational studies has suggested that breastfeeding may reduce the prevalence of obesity in later life. OBJECTIVE The objective was to examine whether initial breastfeeding is related to lower mean body mass index (BMI; in kg/m(2)) throughout life. DESIGN The study was a systematic review of published studies investigating the association between infant feeding and a measure of obesity or adiposity in later life, which was supplemented with data from unpublished sources. Analyses were based on the mean differences in BMI between those subjects who were initially breastfed and those who were formula-fed (expressed as breastfed minus bottle-fed), which were pooled by using fixed-effects models throughout. RESULTS From 70 eligible studies, 36 mean differences in BMI (from 355 301 subjects) between those breastfed and those formula-fed (reported as exclusive feeding in 20 studies) were obtained. Breastfeeding was associated with a slightly lower mean BMI than was formula feeding (-0.04; 95% CI: -0.05, -0.02). The mean difference in BMIs appeared larger in 15 small studies of <1000 subjects (-0.19; 95% CI: -0.31, -0.08) and smaller in larger studies of >or=1000 subjects (-0.03; 95% CI: -0.05, -0.02). An Egger test was statistically significant (P = 0.002). Adjustment for socioeconomic status, maternal smoking in pregnancy, and maternal BMI in 11 studies abolished the effect (-0.10; 95% CI: -0.14, -0.06 before adjustment; -0.01; 95% CI: -0.05, 0.03 after adjustment). CONCLUSIONS Mean BMI is lower among breastfed subjects. However, the difference is small and is likely to be strongly influenced by publication bias and confounding factors. Promotion of breastfeeding, although important for other reasons, is not likely to reduce mean BMI.

Abstract
BACKGROUND The endogenous cholesterol fractional synthesis rate (FSR) is related inversely to infant dietary cholesterol at 4 months of age; however, it remains to be established whether this effect is permanent, possibly contributing to later hypercholesterolemia. OBJECTIVE To determine whether levels of dietary cholesterol in infancy induced changes in FSR and plasma lipid levels that persisted at 18 months. METHODS A prospective clinical trial was conducted with 47 infants, from their first week of life until 18 months of age, who received human milk (HM) until weaned (n = 15) or were randomized to receive modified cow's milk formula (MCF) with added cholesterol (n = 15) or cow's milk formula (CF) (n = 17) for 12 months. Cholesterol contents of HM, MCF, and CF were 120, 80, and 40 mg/L, respectively. FSR and plasma lipid levels were measured at 4 and 18 months. RESULTS At 4 months, total cholesterol and low-density lipoprotein cholesterol levels were higher for infants fed HM and MCF, compared with CF. High-density lipoprotein cholesterol levels were higher in the MCF group than in the HM and CF groups. FSR in the HM group (0.034 +/- 0.005 pools per day) was lower than that in the CF group (0.052 +/- 0.005 pools per day). There was no difference between the HM and MCF (0.047 +/- 0.005 pools per day) groups or between the MCF and CF groups. At 18 months, there were no differences in FSRs or plasma lipid profiles between the groups. CONCLUSION Although cholesterol intake before weaning affects FSRs and plasma lipid profiles at 4 months, these differences do not persist after weaning to an unrestricted diet at 18 months. This provides additional evidence that there is no imprinting of FSR in infancy with differing dietary levels of cholesterol.

Abstract
BACKGROUND Adequate growth is an important indicator of health and well-being in infants. OBJECTIVE Our objective was to determine the effect of supplementing infant formula with long-chain polyunsaturated fatty acids (LCPUFAs) on the growth of term infants. DESIGN Using the methodology outlined by the Cochrane Collaboration, we reviewed all known randomized controlled trials that involved LCPUFA supplementation of infant formula fed to term infants. Outcome measures were weight, length, and head circumference. Original data obtained from the investigators of published trials were used. Outcomes were analyzed with fixed-effects or random-effects model meta-analyses and were reported as weighted mean differences with 95% CIs. RESULTS We identified 14 eligible trials that had data available for meta-analysis (1846 infants). Trial quality was generally high. Meta-analysis showed no significant effect of LCPUFA supplementation on infant weight, length, or head circumference at any assessment age. Similarly, subgroup analyses showed that supplementation with only n-3 LCPUFAs (no arachidonic acid) had no significant effect on infant weight, length, or head circumference. The source of LCPUFA supplementation (phospholipid or triacylglycerol) also did not significantly affect infant growth. CONCLUSION We found no evidence that LCPUFA supplementation of infant formula influences the growth of term infants in either a positive or a negative way.

Abstract
The associations of apolipoprotein B (apoB) gene polymorphisms with blood lipid levels, also accounting for apo E polymorphisms, were assessed in 82 phenylketonuric (PKU) children on diet (34 girls, 48 boys, age 4-12 years, median 8 years). Dietary and plasma biochemical assessments were performed at six-month intervals from the age of 24 months onwards. Apo B (XbaI, MspI, EcoRI restriction sites) and apo E (E2, E3, E4) gene polymorphisms were determined by restriction-enzyme analysis after DNA extraction from blood. Subgroups of apoB polymorphisms were similar for energy intake, dietary lipids and distribution of apo E polymorphisms. Children carrying XbaI X+ / X+ showed higher plasma levels of LDL cholesterol than children carrying X- / X-/+. This gene-related response to dietary habits might play a role also in non-PKU individuals fed low-fat, low-cholesterol diets.

Abstract
BACKGROUND Recent data indicate that cobalamin and folate status, including the metabolic markers methylmalonic acid (MMA) and total homocysteine (tHcy), undergo marked changes during childhood, particularly during the first year. METHODS Serum cobalamin, serum and whole-blood folate, and plasma MMA and tHcy were determined in a cross-sectional study of 700 children, ages 4 days to 19 years. RESULTS During the first 6 months, serum cobalamin was lower than and plasma MMA, tHcy, and serum folate were higher than the concentrations detected in the other age groups. In infants 6 weeks to 6 months of age, median MMA and tHcy concentrations were >0.78 and >75 micro mol/L, respectively. In older children (>6 months), serum cobalamin peaked at 3-7 years and then decreased, median plasma MMA remained low (<0.26 micro mol/L), median plasma tHcy was low (<6 micro mol/L) and increased from the age of 7 years on, and serum folate gradually decreased. Plasma MMA was inversely associated with cobalamin (r = -0.4) in both age groups, but across the whole range of cobalamin concentrations, MMA was markedly higher in infants (< or =6 months) than in older children. Plasma tHcy showed a strong negative correlation to cobalamin (r = -0.52) but not to serum folate in infants < or =6 months. In older children, tHcy showed the expected association with both cobalamin (r = -0.48) and folate (r = -0.51). CONCLUSIONS In infants 6 weeks to 6 months, concentrations of the metabolic markers MMA and tHcy were higher than in the other age groups and strongly correlated to cobalamin, whereas in older children, both makers showed correlations to cobalamin and folate concentrations documented in adults. Whether this metabolic profile in infants is explained by impaired cobalamin status, which in turn may have long-term effects on psychomotor development, remains to be addressed in intervention studies.

Abstract
OBJECTIVE To examine the influence of infant feeding method on serum total cholesterol (TC) and low-density lipoprotein (LDL) cholesterol. METHODS A cross-sectional study of 13- to 16-year-olds and a systematic review of studies (all observational) on the effects of infant feeding on cholesterol in infancy (<1 year), childhood or adolescence (1-16 years), and adulthood (> or =17 years) were conducted using random effects models. Differences are presented as breastfed-bottle-fed. A total of 1532 individuals (92% white; 55% male; mean age: 15.1 years) in 10 British towns were studied, and 37 studies with 52 observations on TC (26 in infancy, 17 in childhood or adolescence, and 9 in adulthood; corresponding figures for LDL were 7, 4, and 6) were reviewed. RESULTS Mean TC in childhood or adolescence (including the new study) was not related to infant feeding pattern (mean TC difference = 0.00; 95% confidence interval [CI]: -0.07 to 0.07 mmol/L). However, in infancy, mean TC was higher among those breastfed (mean TC difference = 0.64; 95% CI: 0.50-0.79 mmol/L), whereas in adults, mean TC was lower among those breastfed (mean TC difference = -0.18; 95% CI: -0.30 to -0.06 mmol/L). Patterns for LDL were similar to those for TC throughout. CONCLUSIONS Breastfeeding is associated with increased mean TC and LDL levels in infancy but lower levels in adulthood/adult life. These results suggest that breastfeeding may have long-term benefits for cardiovascular health and may have implications for the content of formula feed milks.
