Abstract
Increased fruit and vegetable consumption early in life may lead to life-long intake of fruits and vegetables, which in turn may be beneficial for weight control and other health outcomes in later life. Although health officials worldwide recommend delaying solid foods until 6 months of age, younger infants often receive solid food, which may affect later obesity rates. The timing of introduction to solid foods is important both nutritionally and developmentally and may affect acceptance of foods both in infancy and later in life. Infants can clearly discriminate the flavors of different fruits and vegetables. Repeated flavor experiences promote the willingness to eat a variety of foods: infants will consume more of foods that have a familiar flavor and are more accepting of novel flavors if they have experience with flavor variety. Many flavors that the mother either ingests or inhales are transmitted to her milk and/or amniotic fluid. Mothers can help the transition from a diet exclusively of milk or formula to a mixed diet by providing the infant familiar flavors in both milk or formula and solid foods. Exposure to a variety of flavors during and between meals appears to facilitate acceptance of novel foods. Providing novelty in the context of a familiar food might prove to be an optimal combination to progressively accustom infants to a diversity of novel foods. When repeatedly exposing infants to flavors of some vegetables that have bitter tastes, mothers should focus not on infants' facial expressions but on their willingness to eat the food and should continue to provide repeated opportunities to taste the food. Introducing children repeatedly to individual as well as a variety of fruits and vegetables, both within and between meals, might help them be more accepting of fruits and vegetables, which is difficult to enhance beyond toddlerhood.

McCrory C, Layte R. Breastfeeding and risk of overweight and obesity at nine-years of age. Soc Sci Med 2012; 75:323-30. [PMID: 22560796 DOI: 10.1016/j.socscimed.2012.02.048] [Citation(s) in RCA: 57] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2011] [Revised: 11/21/2011] [Accepted: 02/27/2012] [Indexed: 10/28/2022]
Abstract
Whether breastfeeding is protective against the development of childhood overweight and obesity remains the subject of considerable debate. Although a number of meta-analyses and syntheses of the literature have concluded that the greater preponderance of evidence indicates that breastfeeding reduces the risk of obesity, these findings are by no means conclusive. The present study used data from the Growing Up in Ireland study to examine the relationship between retrospectively recalled breastfeeding data and contemporaneously measured weight status for 7798 children at nine-years of age controlling for a wide range of variables including; socio-demographic factors, the child's own lifestyle-related behaviours, and parental BMI. The results of the multivariable analysis indicated that being breastfed for between 13 and 25 weeks was associated with a 38 percent (p < 0.05) reduction in the risk of obesity at nine-years of age, while being breastfed for 26 weeks or more was associated with a 51 percent (p < 0.01) reduction in the risk of obesity at nine-years of age. Moreover, results pointed towards a dose-response patterning in the data for those breastfed in excess of 4 weeks. Possible mechanisms conveying this health benefit include slower patterns of growth among breastfed children, which it is believed, are largely attributable to differences in the composition of human breast milk compared with synthesised formula. The suggestion that the choice of infant feeding method has important implications for health and development is tantalising as it identifies a modifiable health behaviour that is amenable to intervention in primary health care settings and has the potential to improve the health of the population.

Abstract
Background. While rapid early weight gain are common in children who become obese later in life, so is growth faltering in the first 3 months of life. Objective. We seek to determine what relationship weight gain in the first six months of age, separated into two 3-month periods, have with the BMI of children ages 4 to 6 years in an inner-city community. Subjects. A convenience sample cohort of 154 children attending an inner-city clinic. Methods. Consecutive charts were reviewed retrospectively. Age, gender, birth weight and weight change in the first and second 3 months of life were introduced as fixed factors using mixed linear models with BMI in years 4 to 6 as the dependent variable. Results. Weight change quartile in the first 3 months of life did not predict of BMI in years 4 to 6; however, weight changes quartiles during months 4 to 6 were significant predictors for subsequent overweight. Conclusion. The data presented herein suggest that, for this specific population, weight gain can be promoted when it is most essential. It is necessary, however, to identify intermediary variables that could affect outcomes in this and other communities.

Abstract
To determine how characteristics of pregnancy, birth, and early infancy are related to offspring obesity at three critical developmental periods. Mothers were followed through pregnancy and 10-15 years after. Offspring data were obtained through medical record review. Maternal and offspring characteristics were examined to predict obesity in childhood (ages 4-5 years), adolescence (ages 9-14 years), and early adulthood (ages 19-20 years). The original cohort included 802 children born to 795 women. Children who were twins, who had died, or whose mothers had died were excluded (n=25). Medical records of 68.5% of the remaining 777 children documented a height and weight at childhood, adolescence, or early adulthood. Relative risks (RRs) to predict obesity at early adulthood were 12.3 for childhood and 45.1 at adolescence. RRs were also significant to predict obesity at early adulthood between the mother's obesity at prepregnancy (RR=6.4), 4-5 years postpregnancy (RR=6.3), and 10-15 years postpregnancy (RR=6.2). Excluding these variables from the multivariate models and adjusting by gender, birth insurance, and mother's marital status at delivery, the best model to predict obesity at childhood included birth weight, weight gain in infancy, and delivery type. At adolescence, it included maternal pregnancy smoking status, gestational weight gain, and weight gain in infancy, and in early adulthood, included maternal pregnancy smoking status, gestational weight gain, and birth weight. Maternal pregnancy smoking status, gestational weight gain, and weight gain in infancy have long-term effects on offspring. Maternal obesity is the strongest predictor of obesity at all times studied.

Abstract
INTRODUCTION Higher protein intake during the first year of life is associated with increased weight gain velocity and body mass index (BMI). However, the relationship of protein intake and weight gain velocity with body composition is unclear. OBJECTIVE To assess if the increases in weight gain velocity and BMI induced by protein intake early in life are related to an increase in fat or fat-free mass. MATERIALS AND METHODS In all, 41 infants randomized at birth to a higher or lower protein content formula (HP=17 and LP=24, respectively) and 25 breastfed infants were included. Anthropometric measures were assessed at baseline, 6, 12 and 24 months, and fat-free mass (FFM) and fat mass (FM) were assessed by isotope dilution at 6 months. RESULTS Weight gain velocity (g per month) during the first 6 months of life was significantly higher among HP infants (807.8 (±93.8) vs 724.2 (±110.0) (P=0.015)). Weight gain velocity strongly correlated with FM z-score (r=0.564, P<0.001) but showed no association with FFM z-scores. FFM showed no association with BMI. Nevertheless, FM strongly correlated with BMI at 6, 12 and 24 months (r=0.475, P<0.001; r=0.332, P=0.007 and r=0.247, P=0.051, respectively). FFM and FM z-scores did not differ significantly between HP and LP infants (0.32±1.75 vs -0.31±1.17 and 0.54±2.81 vs -0.02±1.65, respectively). CONCLUSION Our findings support the hypothesis that higher protein intakes early in life are associated with faster weight gain and in turn to higher adiposity. This mechanism could be a determinant factor for later obesity risk.

Abstract
OBJECTIVE The objective of this study was to determine the evolution of obesity status (OS) in a longitudinal cohort of low birth weight preterm (LBWPT) infants to an age of 8 years, and to determine whether rapid weight gain in the first year of life independently predicts 8-year OS. STUDY DESIGN In total, 985 infants (birth weight ≤2500 g, gestation age ≤37 weeks) were recruited from the nursery in an eight-site intervention research program and were evaluated at an age of 3, 5, 6.5 and 8 years. Weight and height were measured by standard protocol at each visit and body mass index was calculated. Obesity status is ≥95% for age and sex. Multiple logistic analyses were performed on 8-year OS with predictor variables including infant race, gender, small for gestational age status, birth weight category, neonatal health index, treatment group and first-year weight gain; maternal education and weight status before conception; and HOME Inventory. RESULT Overall, 2.3% were OS at an age of 3 years, 6.1% at an age of 5 years, 7.7% at age 6.5 years and 8.7% at an age 8 years. OS varied by birth weight category at each visit. The infants born ≤1500 g had the lowest prevalence of OS at each age. In the logistic regression, maternal race (Hispanic) (adjusted odds ratio=2.8, confidence interval=1.2 to 6.8), maternal obese status (adjusted odds ratio 3.4, confidence interval=1.5 to 7.8) and first-year weight gain (adjusted odds ratio=2.7, confidence interval=1.9 to 3.9), significantly predicted 8-year OS. CONCLUSION OS is common in LBWPT infants during childhood, and prevalence varies by birth weight category. High weight gain in the first year of life is an important predictor of the development of OS in LBWPT children.

Abstract
To assess the predictive ability of infant weight gain on subsequent obesity we performed a meta-analysis of individual-level data on 47,661 participants from 10 cohort studies from the UK, France, Finland, Sweden, the US and Seychelles. For each individual, weight SD scores at birth and age 1 year were calculated using the same external reference (British 1990). Childhood obesity was defined by International Obesity Task Force criteria. Each +1 unit increase in weight SD scores between 0 and 1 year conferred a twofold higher risk of childhood obesity (odds ratio = 1.97 [95% confidence interval (CI) 1.83, 2.12]), and a 23% higher risk of adult obesity (odds ratio = 1.23 [1.16, 1.30]), adjusted for sex, age and birthweight. There was little heterogeneity between studies. A risk score for childhood obesity comprising weight gain 0-1 year, mother's body mass index, birthweight and sex was generated in a random 50% selection of individuals from general population cohorts with available information (n = 8236); this score showed moderate predictive ability in the remaining 50% sample (area under receiving operating curve = 77% [95% CI 74, 80%]). A separate risk score for childhood overweight showed similar predictive ability (area under receiving operating curve = 76% [73, 79%]). In conclusion, infant weight gain showed a consistent positive association with subsequent obesity. A risk score combining birthweight and infant weight gain (or simply infant weight), together with mother's body mass index and sex may allow early stratification of infants at risk of childhood obesity.

Abstract
OBJECTIVES Increased understanding of the risk factors for childhood obesity has raised the possibility of identifying infants who are at risk of becoming overweight or obese, enabling early intervention for infants at high risk. This paper considers the known risk factors, describes statistical work aimed at identifying risk, and considers the ethical and practical issues of such a development. STUDY DESIGN AND METHODS An overview of the published evidence for risk factors in the early development of overweight and obesity, and a statistical assessment of the practicality of developing a simple obesity risk assessment tool (ORT) for use in the primary care setting. RESULTS Analysis of data from two currently available UK birth cohort studies suggests that an ORT based on these data does not provide acceptable levels of specificity and sensitivity for use in a primary care setting. CONCLUSION Further development of an ORT using additional data and enhanced statistical analysis may lead to a practical tool. However the practical, ethical and legal issues involved in its use, and the public health policy considerations that follow must be resolved.

Abstract
Childhood obesity is a profoundly complex problem and serves as an example of a biospsychosocial issue. Scientific inquiry has provided incredible insight into the complex etiology of weight gain but must be viewed as an interaction between a human's propensity to conserve calories for survival in a world with an abundance of it. This article provides a brief overview divided between biological (nature) and psychosocial and behavioral (nurture) factors.

Abstract
Sub-optimal nutrition during pregnancy has been shown to have long-term effects on the health of offspring in both humans and animals. The most common outcomes of such programming are hypertension, obesity, dyslipidaemia and insulin resistance. This spectrum of disorders, collectively known as metabolic syndrome, appears to be the consequence of nutritional insult during early development, irrespective of the nutritional stress experienced. For example, diets low in protein diet, high in fat, or deficient in iron are all associated with programming of cardiovascular and metabolic disorders when fed during rat pregnancy. In this paper, we hypothesise that the nutritional stresses act on genes or gene pathways common to all of the insults. We have termed these genes and/or gene pathways the “gatekeepers” and hence developed the “gatekeeper hypothesis”. In this paper, we examine the background to the hypothesis and postulate some possible mechanisms or pathways that may constitute programming gatekeepers.

Abstract
Alterations of the intrauterine and neonatal environment may predispose for disorders and diseases throughout later life (perinatal programming). Especially, hormones and nutrients are dose-dependent organizers of the developing organism. Studies in offspring of diabetic mothers (ODM) have paradigmatically contributed to the perception of this developmental principle and our understanding of causal mechanisms. Fetal and neonatal hyperinsulinism in consequence of materno-fetal hyperglycaemia is the pathognomic feature in ODM. Epidemiological, clinical, as well as experimental data indicate that both insulin and glucose, when occurring in elevated concentrations during perinatal life, may epigenetically program a predisposition for obesity and diabetes later on. Similar may occur due to pre- and neonatal overfeeding. From a clinical point of view, avoidance of materno-fetal overnutrition, universal diabetes screening in all pregnant women and adequate therapy of all forms of diabetes during pregnancy, as well as avoidance of neonatal overfeeding are therefore recommended. These measures might serve as causal approaches of a genuine prevention to the benefit of long-term offspring health.

Abstract
The aim of the paper was to compare the growth of rural Croatian infants with 2000 Centers for Disease Control and Prevention (CDC) growth standards and to evaluate the potential preventive influence of breastfeeding on the development of obesity in infancy. Two hundred three infant-mother pairs from Baranja, an Eastern region of Croatia, were enrolled into this study. Retrospective evaluation of infants' medical charts was used to obtain anthropometric data recorded at the birth, 1, 3, 6, 9 and 12 months of age. Infant feeding mode was self-reported by mothers. Breastfed infants gained the least weight of all observed groups. Up to 6 months of age, formula fed infants had the highest weight gain and after 6 months of age, mixed milk fed infants had the highest weight gain. At 12 months of age, 6.4% of all study infants and 7.6% of mixed milk fed infants were at risk of overweight, while the same risk for the group of breastfed infants was 4%. Most of the study infants achieved higher values of body mass and length than the child growth standards. Exclusively breastfed infants, in comparison with other study groups (formula fed infants, mixed milk fed infants and cow's milk fed infants), had lower weight-for-length z-scores during the first year, which suggests that breastfeeding may have a preventive impact on obesity development.

Abstract
Obesity is increasing around the globe. While adult lifestyle factors undoubtedly contribute to the incidence of obesity and its attendant disorders, mounting evidence suggests that programming of obesity may occur following under- and over-nutrition during development. As hypothalamic control of appetite and energy expenditure is set early in life and can be perturbed by certain exposures such as undernutrition and altered metabolic and hormonal signals, in utero exposure to altered maternal nutrition and inadequate nutrition during early postnatal life may contribute to programming of obesity in offspring. Data from animal studies indicate both intrauterine and postnatal environments are critical determinants of the development of pathways regulating energy homeostasis. This review summarizes recent evidence of the impact of maternal nutrition as well as postnatal nutrition of the offspring on subsequent obesity and disease risk of the offspring. While much of the experimental work reviewed here was conducted in the rodent, these observations provide useful insights into avenues for future research into developing preventive measures to curb the obesity epidemic.

Abstract
To examine how urban parents' perceptions of healthy infant size and growth relate to objective weight-for-length percentiles of their children, parents of 222 (69% minority) 6- to 27-month-old infants were surveyed. In all, 41% of parents said growth charts had never been explained to them, and 31% were not confident they understood the meaning of chart percentiles. A total of 20% of parents preferred their child weigh ≥75th percentile, and these children had higher mean weight-for-length percentiles than their peers (P = .05). Similarly, 37% of parents agreed that "a chubby baby is a healthy baby," and these children had higher mean weight-for-length percentiles than others in the cohort ( P = .02). Additionally, 58% of parents ranked a growth curve with consistent growth at the 10th percentile as the "least healthy" of 6 infant growth curves. Growth charts are not consistently explained to or understood by urban parents, and many prefer early life growth patterns associated with later obesity.

Abstract
Excess weight in early life is believed to increase susceptibility to obesity, and in support of such theory, excess weight and fast weight gain in early childhood have been related to overweight later in life. The aim of this study was to review the literature on body size and growth in 0- to 4-year-old children and the association with body size at age 5-13 years. In total, 43 observational studies on body size and/or growth were included, of which 24 studies had been published in 2005 or later. Twenty-one studies considered body size at baseline, and 31 studies considered growth which all included assessment of weight gain. Eight (38%) studies on body size, and 15 (48%) on weight gain were evaluated as high-quality studies. Our results support conclusions in previous reviews of a positive association between body size and weight gain in early childhood, and subsequent body size. Body size at 5-6 months of age and later and weight gain at 0-2 years of age were consistently positively associated with high subsequent body size. Results in this review were mainly based on studies from developed Western countries, but seven studies from developing countries showed similar results to those from developed countries.

Abstract
Childhood obesity has reached epidemic proportions. Many of these children have risk factors for later disease, including cardiovascular disease. For optimal cardiovascular health, health care professionals must be able to identify children and youth at risk and provide appropriate support as needed. The present article reviews the current medical literature on obesity and cardiovascular disease risk factors in the paediatric population, the long-term cardiovascular consequences of childhood obesity and the importance of early life. Recommendations promoting optimal cardiovascular health in all children and youth are discussed.

Overnutrition during the perinatal period has been associated with susceptibility to obesity and related comorbidities. We examined the effects of postnatal early overnutrition on the development of juvenile obesity and the associated renal pathophysiological changes. Three or 10 pups per mother from rat pup litters were assigned to either the overnutrition or control groups during the first 21 days of life. The effects of overfeeding were measured at 28 days. The smaller male litter pups were heavier than the controls between 4 and 28 days after birth (P<.05). By 28 days of age, the kidney weight per body weight ratio decreased in the small litter group (P<.05). Circulating leptin levels increased in the small litter rats (P<.05). Overnutrition had no effect on renal cell proliferation, apoptosis, macrophages and glomerulosclerosis. In the immunoblots and immunohistochemistry, renin and angiotensin II type (AT) 2 receptor expression increased in the overfed rats (P<.05). By contrast, the plasminogen activator inhibitor (PAI)-1 and matrix metalloproteinase (MMP)-9 expression decreased in the overnutrition group (P<.05). The AT 1 receptor, tissue inhibitor of MMP-1, monocyte chemoattractant protein-1, tumor necrosis factor-α, osteopontin and adiponectin expression was not changed. Our data showed that postnatal early overfeeding led to hyperleptinemia, juvenile obesity and the acquired reset of renal maturation. Up-regulation of renin and AT2 and down-regulation of PAI-1 and MMP-9 might contribute to abnormal programming of renal growth in rats exposed to postnatal early overnutrition.

Preventing childhood obesity during infancy in UK primary care: a mixed-methods study of HCPs' knowledge, beliefs and practice. BMC FAMILY PRACTICE 2011; 12:54.

Abstract
BACKGROUND There is a strong rationale for intervening in early childhood to prevent obesity. Over a quarter of infants gain weight more rapidly than desirable during the first six months of life putting them at greater risk of obesity in childhood. However, little is known about UK healthcare professionals' (HCPs) approach to primary prevention. This study explored obesity-related knowledge of UK HCPs and the beliefs and current practice of general practitioners (GPs) and practice nurses in relation to identifying infants at risk of developing childhood obesity. METHOD Survey of UK HCPs (GPs, practice nurses, health visitors, nursery, community and children's nurses). HCPs (n = 116) rated their confidence in providing infant feeding advice and completed the Obesity Risk Knowledge Scale (ORK-10).Semi-structured interviews with a sub-set of 12 GPs and 6 practice nurses were audio recorded, taped and transcribed verbatim. Thematic analysis was applied using an interpretative, inductive approach. RESULTS GPs were less confident about giving advice about infant feeding than health visitors (p = 0.001) and nursery nurses (p = 0.009) but more knowledgeable about the health risks of obesity (p < 0.001) than nurses (p = 0.009). HCPs who were consulted more often about feeding were less knowledgeable about the risks associated with obesity (r = -0.34, n = 114, p < 0.001). There was no relationship between HCPs' ratings of confidence in their advice and their knowledge of the obesity risk.Six main themes emerged from the interviews: 1) Attribution of childhood obesity to family environment, 2) Infant feeding advice as the health visitor's role, 3) Professional reliance on anecdotal or experiential knowledge about infant feeding, 4) Difficulties with recognition of, or lack of concern for, infants "at risk" of becoming obese, 5) Prioritising relationship with parent over best practice in infant feeding and 6) Lack of shared understanding for dealing with early years' obesity. CONCLUSIONS Intervention is needed to improve health visitors and nursery nurses' knowledge of obesity risk and GPs and practice nurses' capacity to identify and manage infants' at risk of developing childhood obesity. GPs value strategies that maintain relationships with vulnerable families and interventions to improve their advice-giving around infant feeding need to take account of this. Further research is needed to determine optimal ways of intervening with infants at risk of obesity in primary care.

Abstract
Background Little is known about the growth of VLBW infants in South Africa. The aim of this study was to assess the growth of a cohort of VLBW infants in Johannesburg. Methods A secondary analysis of a prospective cohort was conducted on 139 VLBW infants (birth weight ≤1500 g) admitted to Charlotte Maxeke Johannesburg Academic Hospital. Growth measurements were obtained from patient files and compared with the World Health Organization Child Growth Standards (WHO-CGS) and with a previous cohort of South African VLBW infants. The sample size per analysis ranged from 11 to 81 infants. Results Comparison with the WHO-CGS showed initial poor growth followed by gradual catch up growth with mean Z scores of 0.0 at 20 months postmenstrual age for weight, -0.8 at 20 months postmenstrual age for length and 0.0 at 3 months postmenstrual age for head circumference. Growth was comparable with that of a previous cohort of South African VLBW infants in all parameters. Conclusions Initial poor growth in the study sample was followed by gradual catch up growth but with persistent deficits in length for age at 20 months postmenstrual age relative to healthy term infants.

Abstract
BACKGROUND In the Netherlands separate reference charts have been developed for native and immigrant groups to deal with differences in growth patterns in later childhood. The use of these charts, however, is complicated by methodological issues; they do not represent all large Dutch immigrant groups in separate charts despite the differences that have been suggested and the evidence of ethnic disparities in growth dates back to 1997. AIM Anthropometric measurements from a contemporary multi-ethnic cohort study were created to quantify differences in childhood growth by creating growth charts, separately for boys and girls between the ages of 0-3 years. SUBJECTS AND METHODS The infants modelled in the charts had a mother born in the Netherlands (n = 3107), Suriname (n = 225), Turkey (n = 203) and Morocco (n = 336). Charts with and without correction for country of origin of the mother were created by using the LMST method. RESULTS All models including the covariate country of origin of the mother fitted the data better (p < 0.0005), but the observed differences were small. CONCLUSION Most remarkable differences were found in the BMI and weight measurements for age charts. Especially girls from mothers born in Turkey and Morocco had an increasingly heavier weight for their age than girls from mothers born in the Netherlands.

Abstract
Objective of the study was to explore factors associated with early childhood obesity and assess whether having a foreign born mother is protective against childhood obesity. Data sources include 9 months and 4 years parent interviews and direct assessments of possessive children's weight and height (4 years) or length (9 months) from the Early Childhood Longitudinal Study-Birth Cohort. Subjects were children with anthropometric measures who lived with their mothers (n = 9,700 at 9 months and 8,200 at 4 years). Overweight is defined as a weight-for-length ratio at or above the 95th percentile at 9 months; obesity is defined as a body mass index at or above the 95th percentile at 4 years. The prevalence of overweight/obesity was 15.4% at 9 months and 18.0% at 4 years. After adjustment for potential confounders, having a foreign-born mother was not associated with the odds of overweight at 9 months or 4 years. At 9 months and 4 years, low birth weight, pre-pregnancy weight and weight gain during pregnancy were protective of overweight. In addition to these factors, at 4 years, excessive weight gain in the first 9 months was the strongest predictors for obesity. Living in a safe neighborhood and ever having breastfed were protective against obesity. Having a foreign born mother is not protective of early childhood obesity. A focus on health of women prior to conception and on women's and infants' health in the perinatal period are key to addressing childhood obesity.

Abstract
AIM To investigate the trends in the size of Finnish children in five birth cohorts from four decades. METHODS This is a retrospective longitudinal growth pattern study on children representing five birth cohorts: 1974, 1981, 1991, 1995 and 2001 from the city of Tampere and three rural municipalities. Growth data were collected from birth to 15 years of age, except in birth cohorts 1995 and 2001 until 12 and 5 years. Body mass index (BMI, kg/m²) was calculated. Pearson's chi-square test was used in analysis. RESULTS The 50th percentile of BMI at birth varied between the 1970's and 2000's (boys: p<0.001, girls: p=0.02), with increase seen in girls. The 50th BMI percentile remained unchanged in 6-month-aged boys, whereas in girls, it varied inconsistent (p=0.04). At 1 and 2 years of age, the 15th, 50th, 85th and 95th BMI percentiles decreased (p=0.26 to <0.001). The 50th BMI percentile remained fairly constant at 5 and 7 years of age. In 12- and 15-year-old boys, the 50th, 85th and 95th percentiles of BMI showed a marked increase (p=0.01 to <0.001). In 12-year-old girls, only the 85th BMI percentile increased (p=0.03). CONCLUSIONS During the last three decades, Finnish toddlers have become markedly slimmer. Concurrently, an opposite change has taken place in adolescent boys.

Abstract
A chronic mismatch of caregiver responsiveness to infant-feeding cues, such as feeding when the infant is not hungry, is hypothesized to have a role in the development of overweight by impairing an infant's response to internal states of hunger and satiation. Although this concept of mismatch or discordance has long been acknowledged in scholarly writings, a systematic assessment of the evidence supporting the role of discordant responsiveness during infant feeding in the early origins of overweight is lacking. This review was undertaken to assess evidence for this hypothesized relationship between discordant responsiveness in feeding and overweight in infancy and toddlerhood, framed within the larger social-environmental context of the infant-caregiver dyad. A systematic method was used to extract articles from three databases of the medical, psychology and nursing fields. The quality of evidence collected was assessed using Oxford University Centre for Evidence Based Medicine's level of evidence and through a narrative review. The systematic search resulted in only nine original research studies, which met a priori inclusion/exclusion criteria. Several studies provide support for the conceptual model, but most were cross-sectional or lower quality prospective studies. The need for consistent definitions, improved measures and longitudinal work is discussed. In conclusion, this review reveals preliminary support for the proposed role of discordant responsiveness in infant/child overweight and at the same time highlights the need for rigorous investigation of responsive feeding interactions in the first years of life.

Abstract
OBJECTIVE To examine the association between timing of introduction of solid foods during infancy and obesity at 3 years of age. METHODS We studied 847 children in Project Viva, a prospective pre-birth cohort study. The primary outcome was obesity at 3 years of age (BMI for age and gender ≥ 95th percentile). The primary exposure was the timing of introduction of solid foods, categorized as <4, 4 to 5, and ≥ 6 months. We ran separate logistic regression models for infants who were breastfed for at least 4 months ("breastfed") and infants who were never breastfed or stopped breastfeeding before the age of four months ("formula-fed"), adjusting for child and maternal characteristics, which included change in weight-for-age z score from 0 to 4 months-a marker of early infant growth. RESULTS In the first 4 months of life, 568 infants (67%) were breastfed and 279 (32%) were formula-fed. At age 3 years, 75 children (9%) were obese. Among breastfed infants, the timing of solid food introduction was not associated with odds of obesity (odds ratio: 1.1 [95% confidence interval: 0.3-4.4]). Among formula-fed infants, introduction of solid foods before 4 months was associated with a sixfold increase in odds of obesity at age 3 years; the association was not explained by rapid early growth (odds ratio after adjustment: 6.3 [95% confidence interval: 2.3-6.9]). CONCLUSIONS Among formula-fed infants or infants weaned before the age of 4 months, introduction of solid foods before the age of 4 months was associated with increased odds of obesity at age 3 years.

Abstract
OBJECTIVE To evaluate whether breastfeeding attenuates increased childhood adiposity associated with exposure to diabetes in utero. RESEARCH DESIGN AND METHODS Retrospective cohort study of 89 children exposed to diabetes in utero and 379 unexposed youth with measured BMI, waist circumference, skinfolds, visceral (VAT) and subcutaneous (SAT) abdominal fat. A measure of breast milk-months was derived from maternal self-report and used to categorize breastfeeding status as low (<6) and adequate (≥ 6 breast milk-months). Multiple linear regression was used to model the relationship between exposure to diabetes in utero and offspring adiposity outcomes among youth stratified according to breastfeeding status. RESULTS Adequate (vs. low) breastfeeding status was associated with significantly lower BMI, waist circumference, SAT, and VAT at ages 6-13 years. Among youth in the low breastfeeding category, exposure to diabetes in utero was associated with a 1.7 kg/m(2) higher BMI (P = 0.03), 5.8 cm higher waist circumference (P = 0.008), 6.1 cm(2) higher VAT (P = 0.06), 44.6 cm(2) higher SAT (P = 0.03), and 0.11 higher ratio of subscapular-to-triceps skinfold ratio (P = 0.008). Among those with adequate breastfeeding in infancy, the effect of prenatal exposure to diabetes on childhood adiposity outcomes was not significant. CONCLUSIONS Adequate breastfeeding protects against childhood adiposity and reduces the increased adiposity levels associated with exposure to diabetes in utero. These data provide support for mothers with diabetes during pregnancy to breastfeed their infants in order to reduce the risk of childhood obesity.

Abstract
OBJECTIVES The purpose of this study was to examine the associations of current body weight and body mass index (BMI) at age three and birth weight in developing chronic respiratory illness in childhood and identify possible interaction underlying its mechanism. METHODS The study was carried out with 422 children who were enrolled in a hospital-based birth cohort. Birth related anthropometric data were collected at birth. At age 3 years, the presence of respiratory symptoms was evaluated by using the Korean version of core questionnaire for wheezing and asthma from the International Study of Asthma and Allergies in Childhood (ISAAC). Physical examination was carried out to measure the child's weight and height. RESULTS Children in the lowest birth weight tertile (aOR = 3.97, 95% CI = 0.94-16.68) or highest BMI tertile (aOR = 3.68, 95% CI = 1.24-10.95) at three years of age were at an increased risk of chronic respiratory illness. Children who were initially in the lowest birth weight tertile but now belong in the highest weight tertile had higher risk of chronic respiratory illness compared to those who had remained in the middle tertile (OR=16.35, 95% CI=1.66-160.57). CONCLUSIONS Children with lower birth weight or higher BMI were at an increased risk of chronic respiratory illness. In addition, children who were initially in the lowest birth weight tertile but are now in the highest weight tertile had higher risk of chronic respiratory illness compared to those who remained in the middle tertile.

Abstract
More than 20% of US children between ages 2 and 5 years are overweight suggesting efforts to prevent obesity must begin earlier. This study tested the independent and combined effects of two behavioral interventions delivered to parents, designed to promote healthy infant growth in the first year. Mother-newborn dyads intending to breastfeed were recruited from a maternity ward. With a 2 × 2 design, 160 dyads were randomized into one of four treatment cells to receive both, one, or no interventions delivered at two nurse home visits. The first intervention ("Soothe/Sleep") instructed parents on discriminating between hunger and other sources of infant distress. Soothing strategies were taught to minimize feeding for non-hunger-related fussiness and to prolong sleep duration, particularly at night. The second intervention ("Introduction of Solids") taught parents about hunger and satiety cues, the timing for the introduction of solid foods, and how to overcome infants' initial rejection of healthy foods through repeated exposure. A total of 110 mother-infant dyads completed the year-long study. At 1 year, infants who received both interventions had lower weight-for-length percentiles (P = 0.009). Participants receiving both interventions had a mean weight-for-length in the 33rd percentile; in contrast, those in other study groups were higher first intervention only--50th percentile; second intervention only--56th percentile; control group--50th percentile).This suggests that multicomponent behavioral interventions may have potential for long-term obesity prevention (ClinicalTrials.gov number, NCT00359242).

Abstract
Excess weight gain in American Indian/Alaskan native (AI/AN) children is a public health concern. This study tested (1) the feasibility of delivering community-wide interventions, alone or in combination with family-based interventions, to promote breastfeeding and reduce the consumption of sugar-sweetened beverages; and (2) whether these interventions decrease Body Mass Index (BMI)-Z scores in children 18-24 months of age. Three AI/AN tribes were randomly assigned to two active interventions; a community-wide intervention alone (tribe A; n = 63 families) or community-wide intervention containing a family component (tribes B and C; n = 142 families). Tribal staff and the research team designed community-tailored interventions and trained community health workers to deliver the family intervention through home visits. Feasibility and acceptability of the intervention and BMI-Z scores at 18-24 months were compared between tribe A and tribes B & C combined using a separate sample pretest, posttest design. Eighty-six percent of enrolled families completed the study. Breastfeeding initiation and 6-month duration increased 14 and 15%, respectively, in all tribes compared to national rates for American Indians. Breastfeeding at 12 months was comparable to national data. Parents expressed confidence in their ability to curtail family consumption of sugar-sweetened beverages. Compared to a pretest sample of children of a similar age 2 years before the study begun, BMI-Z scores increased in all tribes. However, the increase was less in tribes B & C compared to tribe A (-0.75, P = 0.016). Family, plus community-wide interventions to increase breastfeeding and curtail sugar-sweetened beverages attenuate BMI rise in AI/AN toddlers more than community-wide interventions alone.

Abstract
OBJECTIVE To assess the evidence for interventions designed to prevent or reduce overweight and obesity in children younger than 2 years. DATA SOURCES MEDLINE, the Cochrane Central Register of Controlled Trials, CINAHL, Web of Science, and references from relevant articles. STUDY SELECTION Included were published studies that evaluated an intervention designed to prevent or reduce overweight or obesity in children younger than 2 years. DATA EXTRACTION Extracted from eligible studies were measured outcomes, including changes in child weight status, dietary intake, and physical activity and parental attitudes and knowledge about nutrition. Studies were assessed for scientific quality using standard criteria, with an assigned quality score ranging from 0.00 to 2.00 (0.00-0.99 is poor, 1.00-1.49 is fair, and 1.50-2.00 is good). DATA SYNTHESIS We retrieved 1557 citations; 38 articles were reviewed, and 12 articles representing 10 studies met study inclusion criteria. Eight studies used educational interventions to promote dietary behaviors, and 2 studies used a combination of nutrition education and physical activity. Study settings included home (n = 2), clinic (n = 3), classroom (n = 4), or a combination (n = 1). Intervention durations were generally less than 6 months and had modest success in affecting measures, such as dietary intake and parental attitudes and knowledge about nutrition. No intervention improved child weight status. Studies were of poor or fair quality (median quality score, 0.86; range, 0.28-1.43). CONCLUSIONS Few published studies attempted to intervene among children younger than 2 years to prevent or reduce obesity. Limited evidence suggests that interventions may improve dietary intake and parental attitudes and knowledge about nutrition for children in this age group. For clinically important and sustainable effect, future research should focus on designing rigorous interventions that target young children and their families.

Abstract
BACKGROUND In several studies, since high and low birth weights are demonstrated as associated with obesity in childhood, these values should be followed up and documented carefully. OBJECTIVE The aim of this retrospective cohort study is to demonstrate the variation on body mass index outcomes of large (LGA), small (SGA), appropriate (AGA) for gestational age infants from birth to the end of fourth year of age and the effects of breastfeeding duration on these outcomes. METHODS AND RESULTS Four hundred and seven infants were recruited in the study (304AGA, 85 LGA, 18 SGA infants). LGA was frequent in boys and SGA in girls (p = 0.001). The mothers with gestational diabetes mellitus did have LGA infants (10.0% vs. 3.3%) (p = 0.022). The SGA infants performed rapid catch-up growth in the second month while the LGA infants performed catch-down growth in the ninth month. After the first 4 months, there was no difference on the values of BMI depending on breastfeeding time, less or more than 4 months, on the basis of the AGA and LGA infants. However, the body mass index (BMI) of LGA infants breastfed more than 12 months were not different from the AGA; unless the breastfeeding ceased earlier, the means of BMI remained significantly higher until 3 years. CONCLUSION Consequently, long duration of breastfeeding might protect LGA infants from childhood obesity risk.

Abstract
PURPOSE To analyze the usefulness of the weight gain/height gain ratio from birth to two and three years of age as a predictive risk indicator of excess weight at preschool age. METHODS The weight and height/length of 409 preschool children at daycare centers were measured according to internationally recommended rules. The weight values and body mass indices of the children were transformed into a z-score per the standard method described by the World Health Organization. The Pearson correlation coefficients (rP) and the linear regressions between the anthropometric parameters and the body mass index z-scores of preschool children were statistically analyzed (alpha = 0.05). RESULTS The mean age of the study population was 3.2 years (± 0.3 years). The prevalence of excess weight was 28.8%, and the prevalence of overweight and obesity was 8.8%. The correlation coefficients between the body mass index z-scores of the preschool children and the birth weights or body mass indices at birth were low (0.09 and 0.10, respectively). There was a high correlation coefficient (rP = 0.79) between the mean monthly gain of weight and the body mass index z-score of preschool children. A higher coefficient (rP = 0.93) was observed between the ratio of the mean weight gain per height gain (g/cm) and the preschool children body mass index z-score. The coefficients and their differences were statistically significant. CONCLUSION Regardless of weight or length at birth, the mean ratio between the weight gain per g/cm of height growth from birth presented a strong correlation with the body mass index of preschool children. These results suggest that this ratio may be a good indicator of the risk of excess weight and obesity in preschool-aged children.

Abstract
Purpose. To estimate the prevalence of U.S. children's overweight risk and obesity at age 9 months and at age 2 years, to assess weight changes between the two periods, and to examine relationships between weight status (i.e., normal, at risk, or obese) changes and demographic variables. Design. Analyses of children's early weight trajectories and related demographic characteristics from the Early Childhood Longitudinal Study–Birth Cohort (ECLS-B) are presented. Setting. United States. Subjects. The 9-month-old (n = 8900) and 2-year-old (n = 7500) ECLS-B waves were used to generate nationally representative estimates of obese and at-risk children born in 2001. Measures. Measures included child's sex, race/ethnicity, socioeconomic status, community locale, geographic region, and weight status. Analysis. Logistic and multinomial logistic regression models were used to determine the odds of children's demographic characteristics being related to weight persistence, loss, or gain. Results. Approximately one-third of U.S. children were either at risk or obese at 9 months (31.9%) and at 2 years (34.3%). Some children were at greater risk (e.g., Hispanics and low socioeconomic status children), while others had reduced risk (e.g., females and Asian/Pacific Islanders). Additional results from two trajectory models generally corroborated patterns of status change due to weight gain. Conclusions. Between age 9 months and age 2 years, U.S. children consistently moved toward less desirable weight status. Obesity risk was not uniform across demographic subgroups, suggesting that health policy might focus on those children at greatest risk. (Am J Health Promot 2011;25[3]:190–198.)

Abstract
Background Efforts to prevent the development of overweight and obesity have increasingly focused early in the life course as we recognise that both metabolic and behavioural patterns are often established within the first few years of life. Randomised controlled trials (RCTs) of interventions are even more powerful when, with forethought, they are synthesised into an individual patient data (IPD) prospective meta-analysis (PMA). An IPD PMA is a unique research design where several trials are identified for inclusion in an analysis before any of the individual trial results become known and the data are provided for each randomised patient. This methodology minimises the publication and selection bias often associated with a retrospective meta-analysis by allowing hypotheses, analysis methods and selection criteria to be specified a priori. Methods/Design The Early Prevention of Obesity in CHildren (EPOCH) Collaboration was formed in 2009. The main objective of the EPOCH Collaboration is to determine if early intervention for childhood obesity impacts on body mass index (BMI) z scores at age 18-24 months. Additional research questions will focus on whether early intervention has an impact on children's dietary quality, TV viewing time, duration of breastfeeding and parenting styles. This protocol includes the hypotheses, inclusion criteria and outcome measures to be used in the IPD PMA. The sample size of the combined dataset at final outcome assessment (approximately 1800 infants) will allow greater precision when exploring differences in the effect of early intervention with respect to pre-specified participant- and intervention-level characteristics. Discussion Finalisation of the data collection procedures and analysis plans will be complete by the end of 2010. Data collection and analysis will occur during 2011-2012 and results should be available by 2013. Trial registration number ACTRN12610000789066

Abstract
Little is known about the association between prenatal cocaine exposure and obesity. We tested whether prenatal cocaine exposure increases the likelihood of obesity in 561 9-year-old term children from the Maternal Lifestyle Study (MLS). Overall, 21.6% of children met criterion for obesity (body mass index [BMI] ≥ 95th percentile, age and sex-specific). While there was no overall cocaine effect on obesity, multivariate logistic analysis revealed that children exposed to cocaine but not alcohol were 4 times more likely to be obese (OR 4.11, CI 2.04-9.76) than children not exposed to either drug. No increase in obesity prevalence was found in children exposed to alcohol but not cocaine (OR 1.08, CI .59-1.93) or both (OR 1.21, CI 0.66-2.22). Alcohol exposure may attenuate the effect of cocaine exposure on obesity. Increased obesity associated with cocaine but not alcohol exposure was first observed at 7 years. BMI was also elevated from 3 to 9 years in children exposed to cocaine but not alcohol, due to increasing weight but normal height. Prenatal exposure to cocaine may alter the neuroendocrine system and metabolic processes resulting in increased weight gain and childhood obesity.

Abstract
Background/Objectives: Protein concentration is lower in human milk (HM) than in infant formula. The objective of this study was to evaluate the effect of an α-lactalbumin-enriched formula with a lower protein concentration on infant growth, protein markers and biochemistries. Subjects/Methods: Healthy term formula-fed (FF) infants 5–14 days old were randomized in this controlled, double-blind trial to standard formula (SF: 14.1 g/l protein, 662 kcal/l) group (n=112) or experimental formula (EF: 12.8 g/l protein, 662 kcal/l) group (n=112) for 120 days; a HM reference group (n=112) was included. Primary outcome was weight gain (g/day) from D0 to D120. Secondary outcomes included serum albumin, plasma amino acids insulin and incidence of study events. Anthropometric measures were expressed as Z-scores using 2006 World Health Organization growth standards. Results: A total of 321 of the 336 infants (96%) who enrolled, completed the study. Mean age was 9.6 (±2.9) days; 50% were girls. Mean weight gain (g/day) did not significantly differ between SF vs EF (P=0.67) nor between EF vs HM (P=0.11); however weight gain (g/day) was significantly greater in the SF vs HM group (P=0.04). At day 120, mean weight-for-age Z-score (WAZ) and weight-for-length Z-score (WLZ) did not significantly differ between SF vs EF nor EF vs HM; however the WAZ was significantly greater in SF vs HM (P=0.025). Secondary outcomes were within normal ranges for all groups. Incidence of study events did not differ among groups. Conclusions: α-Lactalbumin-enriched formula containing12.8 g/l protein was safe and supported age-appropriate growth; weight gain with EF was intermediate between SF and HM groups and resulted in growth similar to HM-fed infants in terms of weight gain, WAZ and WLZ.

Abstract
BACKGROUND Growth acceleration as a consequence of relative overnutrition in infancy has been suggested to increase the risk of later obesity. However, few studies have investigated this association by using an experimental study design. OBJECTIVE We investigated the effect of early growth promotion on later body composition in 2 studies of infants born small for gestational age (weight <10th percentile in study 1 and <20th percentile in study 2). DESIGN We reviewed a subset of children (n = 153 of 299 in study 1 and 90 of 246 in study 2) randomly assigned at birth to receive either a control formula or a nutrient-enriched formula (which contained 28-43% more protein and 6-12% more energy than the control formula) at 5-8 y of age. Fat mass was measured by using bioelectric impedance analysis in study 1 and deuterium dilution in study 2. RESULTS Fat mass was lower in children assigned to receive the control formula than in children assigned to receive the nutrient-enriched formula in both trials [mean (95% CI) difference for fat mass after adjustment for sex: study 1: -38% (-67%, -10%), P = 0.009; study 2: -18% (-36%, -0.3%), P = 0.04]. In nonrandomized analyses, faster weight gain in infancy was associated with greater fat mass in childhood. CONCLUSIONS In 2 prospective randomized trials, we showed that a nutrient-enriched diet in infancy increased fat mass later in childhood. These experimental data support a causal link between faster early weight gain and a later risk of obesity, have important implications for the management of infants born small for gestational age, and suggest that the primary prevention of obesity could begin in infancy.

Abstract
OBJECTIVE Breastfeeding and infant weight change are both associated with adiposity. We examined the extent to which infant weight change mediates the association between breastfeeding and adiposity at age 3 years. METHODS We studied 884 children in a prospective cohort study. We determined breastfeeding status in the first 6 months. Our primary outcomes at 3 years were body mass index (BMI) z score and the sum of subscapular and triceps skinfold thicknesses (SS + TR); we also assessed obesity. We defined infant weight change as change in weight-for-age z score between birth and 6 months. We performed multivariable regression analyses. RESULTS At age 6 months, 25.0% of infants were fully breastfed. At age 3 years, mean (standard deviation) BMI z score was 0.45 (1.03). In linear regression analyses adjusted for mother's educational level, race/ethnicity, smoking, BMI, pregnancy weight gain and birth weight (adjusted for gestational age), the BMI z score of fully breastfed children was 0.17 (95% CI: -0.43, 0.09) units lower than never breastfed children. After additional adjustment for infant weight change, the estimate was attenuated (-0.03, 95% CI: -0.27, 0.20). Adjustment for infant weight change only modestly attenuated estimates for SS + TR (from -1.48 mm [95% CI: -2.52, -0.44] to -1.16 mm [95% CI: -2.18, -0.14]), and for the odds of being obese (from 0.21 [95% CI: 0.07, 0.68] to 0.29 [95% CI: 0.08, 1.05]). CONCLUSION Infant weight change between birth and 6 months mediates associations of breastfeeding with BMI, but only partially with indicators of child adiposity.

Abstract
The aim of this project was to collect data from focus-group participants to inform the future development of region-specific educational strategies to modify infant-feeding practices that may predispose children to obesity. Infant-feeding perceptions and practices were collected from participants of the Special Supplemental Nutrition Program for Women, Infants, and Children, through recorded focus groups, in two East Tennessee counties. Focus groups replaced the participants' required, prescheduled nutrition-education classes for participants with infants younger than 6 months of age. Twenty-nine focus groups were convened and recorded, reaching a total of 109 participants. Results of this series of focus groups indicate that the Special Supplemental Nutrition Program for Women, Infants, and Children population in rural East Tennessee was similar to populations elsewhere in terms of early solid-food introduction, frequent switching of formula, and sources of and valuation of infant-feeding advice. However, this population seemed to be different in the magnitude at which they introduce infant cereal early (primarily as an addition to the bottle). For this reason, interventions designed to reduce inappropriate infant-feeding behaviors in this population should focus on early introduction of solid food (especially infant cereal) first. In addition to these findings, a model of infant-feeding strategy development based on caregiver-orientation (framed within parenting styles) is presented and discussed.

Abstract
We sought to determine the association between small for gestational age (SGA), birth weight, and childhood obesity within preterm polysubstance exposed children. We sampled 312 preterm children with 11-year body mass index (BMI; age- and sex-specific) data from the Maternal Lifestyle Study (51% girls, 21.5% SGA, 46% prenatal cocaine, and 55% tobacco exposed). Multinomial regression analyzed the association between 11-year obesity (OBE) and overweight (OW) and SGA, birth weight, first-year growth velocity, diet, and physical activity variables. Overall, 24% were OBE (BMI for age ≥95th percentile) and 16.7% were OW (BMI ≥85th and <95th percentiles). In adjusted analyses, SGA was associated with OW (odds ratio [OR] = 3.4, confidence interval [CI] 1.5 to 7.5). Higher birth weight was associated with OBE (OR = 1.8, CI 1.3 to 2.4) and OW (OR = 1.4, CI 1.1 to 2.0). Growth velocity was associated with OBE (OR = 2.7, CI 1.8 to 4.0) and OW (OR = 1.6, CI 1.1 to 2.4). Low exercise was associated with OBE (OR = 2.1, CI 1.0 to 4.4) and OW (OR = 2.1, CI 1.0 to 4.5). There was no effect of substance exposure on obesity outcomes. Many (41%) of these high-risk preterm 11-year-olds were obese/overweight. Multiple growth-related processes may be involved in obesity risk for preterm children, including fetal programming as indicated by the SGA effect.

Abstract
As the prevalence of childhood obesity increases, researchers continue to attempt to identify factors contributing to obesity. The purpose of this study was to define the relationship between birth weight, rapid weight gain (RWG), and early childhood obesity in a low-income, inner-city minority population. In this retrospective chart review, researchers documented every medical encounter recorded in the chart from birth to 3 years for 203 3 year old minority children from low-income families living in an urban area. Based on Center for Disease Control and Prevention's growth charts and tables, z-scores at birth, 4 months, and 1 year were calculated and RWG determined. Researchers determined Body Mass Index percentiles at 3 years of age using the last available weight and height between 24 and 38 months of age. Eight percent of children were underweight, 62% were normal weight, 12% were at overweight and 18% were obese. Children who experienced RWG during the first year of life were 9.24 (CI: 3.73-22.91) as likely to become obese as those who did not experience RWG. Neither low birth weight nor being male increased the odds of becoming obese. Low birth weight predicted underweight at 24-38 months. In this high-risk population, children experiencing RWG during the first year of life have a significantly increased risk of being obese during the preschool years. Future research should identify factors leading to RWG, including specific infant feeding practices.

Abstract
OBJECTIVE To evaluate the association between adiposity at birth and in infancy with overweight at age 5 years. This study hypothesizes that adiposity at birth as approximated by body mass index (BMI) predicts childhood fatness. METHODS Anthropomorphic data from birth to 5 years were used to calculate BMI percentiles. Multiple logistic regression assessed the association between BMI percentile > or =85% at 2 weeks and BMI percentile > or =85% at 6, 12, 36, and 60 months. RESULTS Elevated BMI at age 2 weeks > or =85th percentile was associated with significant increases in risk of overweight at 6, 12, 36, and 60 months of age. Infants with a BMI at age 2 weeks > or =85th percentile had an adjusted odds ratio of 3.42 (95% confidence interval [CI] = 1.79, 6.50) and an adjusted risk ratio of 2.12 (95% CI = 1.71, 2.61) of being overweight at 60 months of age. CONCLUSIONS Adiposity at birth as approximated by BMI is a significant predictor of overweight at 5 years.
