Abstract
OBJECTIVES Infant formulas provide more protein than breast milk. High protein intakes, as well as maternal obesity, are risk factors for later obesity. The present study tested whether a formula with lower protein content slows weight gain of infants of overweight mothers (body mass index [BMI] >25 kg/m). METHODS In a randomized double-blind study infants of overweight mothers received from 3 months an experimental (EXPL) formula with 1.65 g of protein/100 kcal (62.8 kcal/100 mL) and containing probiotics, or a control (CTRL) formula with 2.7 g of protein/100 kcal (65.6 kcal/100 mL). Breast-fed infants were studied concurrently. Primary assessment was between 3 and 6 months, although formulas were fed until 12 months. Biomarkers of protein metabolism (blood urea nitrogen, insulin growth factor-1, insulinogenic amino acids) were measured. RESULTS Infants fed the low-protein EXPL formula gained less weight between 3 and 6 months (-1.77 g/day, P=0.024) than infants fed the CTRL formula. In the subgroup of infants of mothers with BMI>30 kg/m the difference was -4.21 g/day (P=0.017). Weight (P=0.011) and BMI (P=0.027) of EXPL infants remained lower than that of CTRL infants until 2 years but were similar to that of breast-fed infants. Blood urea nitrogen, insulin growth factor-1, and insulinogenic amino acids at 6 months were significantly lower in EXPL compared with CTRL. CONCLUSIONS A low-protein formula with probiotics slowed weight gain between 3 and 6 months in infants of overweight mothers. Weight gain and biomarkers were more like those of breast-fed infants.

Effects of body size and change in body size from infancy through childhood on body mass index in adulthood. Int J Obes (Lond) 2014; 38:1305-11. [PMID: 24942870 DOI: 10.1038/ijo.2014.108] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/10/2014] [Revised: 05/19/2014] [Accepted: 06/10/2014] [Indexed: 11/09/2022]
Abstract
BACKGROUND Weight and weight gain throughout infancy are related to later obesity, but whether the strength of the associations varies during the infancy period is uncertain. AIMS Our aims were to identify the period of infancy when change in body weight has the strongest association with adult body mass index (BMI) and also the extent to which these associations during infancy are mediated through childhood BMI. METHODS The Copenhagen Perinatal Cohort, in which participants were followed from birth through 42 years of age, provided information on weight at 12 months and BMI at 42 years for 1633 individuals. Information on weight at birth, 2 weeks, 1, 2, 3, 4 and 6 months was retrieved from health visitors' records and information on BMI at ages 7 and 13 years from school health records. The associations of infant weight and weight gain standard deviation scores (SDS) with adult BMI-SDS were analyzed using multiple linear regression and path analysis. RESULTS Higher-weight-SDS at all ages from birth to an age 12 months were associated with higher-BMI-SDS at 42 years (regression coefficients 0.08-0.12). Infant weight gain-SDS was associated with greater BMI-SDS at 42 years only between birth and 3 months (0.09, 95% confidence intervals (CI) 0.04, 0.15) driven by an association between 2 and 3 months (0.12, 95% CI: 0.04, 0.20). The latter was partly mediated through later BMI in the path analysis. Infant weight gain-SDS between 3 and 12 months was not associated with greater BMI-SDS at 42 years. CONCLUSIONS Faster weight gain during only the first 3 months of infancy was associated with increased adult BMI, although not in a consistent monthly pattern. Adult BMI is more sensitive to high weight gain during early infancy than late infancy, but not specifically to the first month of life.

Abstract
Growth acceleration or catch-up growth (CUG) in early infancy is a plausible risk factor for later obesity and cardiovascular disease. We postulate that this risk may be mediated by an adverse programming of body composition by CUG in early infancy. The study was aimed at evaluating the association between the pattern of gain in weight and length of term low birth weight (LBW) infants from birth to 6 months, with fat mass percent (FM%) at 6 months. Term healthy singleton LBW infants were enrolled. Baby’s weight and length z-scores were measured at birth and three follow-up visits. Body composition was measured by dual-energy absorptiometry at last visit. A total of 54 babies (28 boys) were enrolled. The mean birth weight and gestation were 2175±180 g and 37.6±0.6 weeks. Follow-up visits were at 1.4±0.0, 3.0±0.3 and 7.2±0.8 months. The proportion of babies who showed CUG [increase in weight for age z-score (∆WAZ)>0.67] from birth to 1.4, 3.0 and 7.2 months was 29.6, 26.4 and 48.5%, respectively. The mean FM% at 7.2 months was 16.6±7.8%. Infants with greater ∆WAZ from birth to 3 and 7.2 months had significantly greater FM% at 7.2 months after adjusting for current age, size and gender. Infants with early CUG (<1.4 months) had higher FM% than infants with no CUG. We conclude that earlier and greater increment in WAZ is positively associated with FM%.

Abstract
UNLABELLED What is already known about this subject Samoan adults are recognized for their particularly high body mass index and prevalent obesity. While Polynesians are understudied, in other populations infancy is a critical period in the development of obesity. Breastfeeding has been shown to attenuate obesity risk. What this study adds Samoan infants show remarkably rapid gain in weight but not length in early infancy resulting in a prevalence of overweight and obesity far higher than has been previously reported elsewhere. Breastfeeding is associated with slower weight gain in infancy suggesting that its protective benefits for obesity risk are generalizable outside of European-derived populations. BACKGROUND Samoans are recognized for their particularly high body mass index and prevalent adult obesity but infants are understudied. OBJECTIVE To examine the prevalence of overweight and obesity and determine the contribution of feeding mode to obesogenic growth trajectories in American Samoan infants. METHODS Data were extracted from the well baby records of 795 (n = 417 male) Samoan infants aged 0-15 months. Mixed-effects growth models were used to produce individual weight and length curves. Further mixed-effects models were fitted with feeding mode (breastfed, formula- or mixed-fed) as a single observation at age 4 (±2) months. Weight and length values were converted to z-scores according to the Centers for Disease Control 2000 reference. RESULTS At 15 months, 23.3% of boys and 16.7% of girls were obese (weight-for-length > 95th percentile). Feeding mode had a significant effect on weight and length trajectories. Formula-fed infants gained weight and length faster than breastfed infants. Formula-fed boys were significantly more likely to be obese at 15 months (38.6%) than breastfed boys (23.4%), χ(2) = 8.4, P < 0.01, odds ratio = 2.05, 95% confidence interval (1.04, 4.05). CONCLUSION Obesity in American Samoans is not confined to adults. Obesity prevention efforts should be targeted at early life and promotion of breastfeeding may be a suitable intervention target.

Abstract
The nationwide epidemic of pediatric obesity is more prevalent among Hispanic children than white children. Recent literature suggests that obesity has early origins, leading scholars to call for interventions in pregnancy and infancy. However, there is little theoretical or empirical research to guide the development of early prevention programs for Hispanics. The present study seeks to identify risk factors for early childhood obesity among a low-income, predominately Hispanic sample. Data were gathered to inform the design of a primary care childhood obesity prevention program targeting pregnancy through age 12 months. Baseline data were gathered on 153 women attending the clinic for prenatal care or for their child's 2, 6 or 12 month well-check. All women completed surveys on diet, exercise, social support, food security, stress, infant feeding practices, health, and demographics. For women with children (n = 66), survey data were matched with medical records data on infant weight. Results reveal that 55 % of women in the sample had an infant profiling in the 85th percentile or higher, confirming the need for an early childhood obesity intervention. While mothers exhibited several potential risk factors for childhood obesity (e.g. fast food consumption), only maternal consumption of sweets and sugar-sweetened beverages, stress, and SNAP (food stamp receipt) were associated with infant overweight. Findings further reveal that stress and SNAP relate to child overweight, in part, through mothers' sugar-sweetened beverage consumption. Results suggest that obesity prevention efforts must address specific individual choices as well as the external environment that shapes these consumption patterns.

Abstract
Introduction Interventions that make extensive use of theory tend to have larger effects on behaviour. The Intervention Mapping (IM) framework incorporates theory into intervention design, implementation and evaluation, and was applied to the development of a community-based childhood obesity prevention intervention for a multi-ethnic population. Methods IM was applied as follows: 1) Needs assessment of the community and culture; consideration of evidence-base, policy and practice; 2) Identification of desired outcomes and change objectives following identification of barriers to behaviour change mapped alongside psychological determinants (e.g. knowledge, self-efficacy, intention); 3) Selection of theory-based methods and practical applications to address barriers to behaviour change (e.g., strategies for responsive feeding); 4) Design of the intervention by developing evidence-based interactive activities and resources (e.g., visual aids to show babies stomach size). The activities were integrated into an existing parenting programme; 5) Adoption and implementation: parenting practitioners were trained by healthcare professionals to deliver the programme within Children Centres. Results HAPPY (Healthy and Active Parenting Programme for Early Years) is aimed at overweight and obese pregnant women (BMI > 25); consists of 12 × 2.5 hr. sessions (6 ante-natal from 24 weeks; 6 postnatal up to 9 months); it addresses mother’s diet and physical activity, breast or bottle feeding, infant diet and parental feeding practices, and infant physical activity. Conclusion We have demonstrated that IM is a feasible and helpful method for providing an evidence based and theoretical structure to a complex health behaviour change intervention. The next stage will be to assess the impact of the intervention on behaviour change and clinical factors associated with childhood obesity. The HAPPY programme is currently being tested as part of a randomised controlled feasibility trial.

Abstract
Maternal undernutrition increases the risk of type 2 diabetes and metabolic syndrome later in life, particularly upon postnatal exposure to a high-energy diet. However, dysfunctions of, for example, the glucose-insulin axis are not readily detectable by conventional tests early in life, making it difficult to identify individuals at risk. Thus, other methods are required. We hypothesised that prenatally undernourished individuals (but not postnatally overnourished ones) are adapted to a life with limited food availability, which would be evident under conditions reflecting starvation, stress and short-term abundance of food. In this study, twin-pregnant sheep were fed diets meeting 100% (NORM) or 50% (LOW) of energy and protein requirements during the last trimester. Twin offspring were fed either a normal moderate (CONV) diet or a high-carbohydrate-high-fat (HCHF) diet from 3 days to 6 months of age (approximately puberty) and the same moderate diet thereafter until 2 years of age (young adulthood; only females), resulting in four groups: NORM-CONV, LOW-CONV, NORM-HCHF and LOW-HCHF. At the age of 6 months and 2 years respectively, they were subjected to fasting and propionate (nutrient abundance) and adrenalin challenges. At 6 months of age, postnatal HCHF diet exposure caused metabolic alterations, reflecting hypertriglyceridaemia and altered pancreatic β-cell secretion. Irrespective of postnatal diet, prenatal undernutrition was found to be associated with unexpected endocrine responses of leptin, IGF1 and cortisol during fasting (lack of or the opposite response compared with the controls) in 2-year-old adults. In conclusion, a HCHF diet interfered with β-cell function, whereas maternal undernutrition did not lead to any changes in the LOW offspring, except to abnormal hormone responses, suggesting that fetal programming interferes with hypothalamic integration of important endocrine axis.

Abstract
OBJECTIVE To test whether weight and the weight gain rate during different age periods are associated with being overweight/obese at 10 years of age. METHODS A nested case-control study was performed in a clinical historic cohort that was selected based on medical records from the Albert Einstein Hospital Social Program in São Paulo, Brazil. A sample of 378 eutrophic and overweight/obese children was analyzed. RESULTS After adjusting for birth weight and gestational age, the likelihood of being overweight/obese at 10 years of age was 4.04-fold greater when progressing from one quartile of weight gain to the immediately superior quartile in the first semester of life and 3.24-fold greater when this occurred from 2-5 years of age. A one-quartile change in weight gain in the first semester was associated with a 0.5 z-score increase in BMI at age 10. A robust independent effect of weight at age 5 confirmed that earlier weight gain was an important predictor. CONCLUSIONS The amount of weight gain during the first 6 months of life and between 2 and 5 years of age and weight at age 5 were important predictors of overweight/obesity at 10 years of age.

Abstract
OBJECTIVE To describe the perspective and strategies of family child care providers (FCCPs) to reduce children's suboptimal weight trajectories. DESIGN In-person, in-depth interviews with FCCPs. SETTING Family child care homes. PARTICIPANTS Seventeen FCCPs caring for children 6 weeks to 9 years old; 94% caring for children paying with a state subsidy. PHENOMENON OF INTEREST Strategies of FCCP to reduce children's suboptimal weight trajectories. ANALYSIS Constant comparative method of qualitative data analysis. RESULTS Family child care providers described 3 core strategies: (1) improving children's behavior, (2) engaging and educating parents, and (3) leveraging influences external to their relationship with parents to effect positive change and to avoid parental conflict. These strategies were framed within their knowledge of child development, parental communication, and community services. CONCLUSIONS AND IMPLICATIONS The findings suggest that FCCPs' role in obesity prevention may be framed within knowledge that may be commonly expected of a child care provider. Partnerships between public health policy makers and FCCP may reduce obesigenic environments by employing training and resources that link obesity prevention and child care provider expertise.

Abstract
Background Childhood obesity increases the risk of obesity in adulthood and is associated with cardiovascular disease risk factors. Our aim was to assess the early life risk factors associated with overweight and obesity among preschool children. Methods In this case–control study, from the 1087 preschool children measured, age, sex and ethnicity matched 71 cases and 71 controls were recruited. Cases and controls were defined according to the WHO 2006 growth standards. The birth and growth characteristics were extracted from the child health development records. Infant feeding practices and maternal factors were obtained from the mother. Rapid weight gain was defined as an increase in weight-for-age Z score (WHO standards) above 0.67 SD from birth to 2 years. The magnitude and significant difference in mean values of the variables associated with overweight and obesity were evaluated using logistic regressions and paired t-test, respectively. Results Cases had significantly shorter duration (months) of breastfeeding (19.4, 24.6, p = 0.003), and smaller duration (months) of exclusive breastfeeding (3.7, 5.1, p = 0.001) compared to controls. Rapid weight gain (OR = 6.3, 95% CI = 2.04–19.49), first born status (OR = 3.6, 95% CI = 1.17-10.91) and pre-pregnancy obesity (OR = 4.0, 95% CI = 1.46-10.76) were positively associated with overweight and obesity. Breastfeeding more than 2 years (OR = 0.2, 95% CI = 0.06-0.57) was negatively associated with overweight and obesity. Conclusion Rapid weight gain within first two years, first–born status and pre-pregnancy obesity of the mother contributed for preschool obesity. Our results suggest that intervention may be indicated earlier in infancy and during the toddler and preschool years to tackle the increasing prevalence of obesity.

Abstract
BACKGROUND Appropriate nutrition during childhood is important for preventing future development of lifestyle-related diseases. The effect of feeding choice on infant growth in Japan is not known. METHODS Data from 204 healthy schoolchildren (age, 6-9 years) were obtained retrospectively from their parents by questionnaires. Breast-fed (BF) and formula-fed (FF) groups were defined as those fed only breast milk or formula milk at 4 months of age, respectively. There were 71 children (M/F, 31/40) in BF and 30 (M/F, 19/11) in FF. Anthropometric data at birth, and at 1, 4, 7, 10, 18, and 36 months of age in male and female infants were compared between the groups. RESULTS In male infants, height was significantly lower at 4 months, bodyweight was lower from 4 to 18 months, and body mass index (BMI) was lower from 10 to 36 months in BF than in FF. The standard deviation scores (SDS) for height, weight and BMI had a similar pattern. No significant differences were observed for these variables for female infants in BF compared with FF. Multiple regression analysis showed that birthweight, mother's pre-pregnancy weight, and infant feeding choice were significant factors associated with weight-SDS at 18 and 36 months. Feeding choice was the only factor associated with BMI-SDS at 18 months. CONCLUSIONS Infant feeding choice had a gender-associated effect on growth during infancy. When evaluating infant growth, not only birthweight and mother's pre-pregnancy weight, but also infant feeding choice and gender should be considered.

Abstract
OBJECTIVE To systematically examine infant size and growth, according to the 2006 WHO infant growth standards, as risk factors for overweight status in young adulthood in a historical cohort. Specifically, to assess: Whether accounting for length (weight-for-length) provides a different picture of risk than weight-for-age, intervals of rapid growth in both weight-for-age and weight-for-length metrics, and what particular target ages for infant size and intervals of rapid growth associate most strongly with overweight as a young adult. PATIENTS/METHODS Data analysis of 422 appropriate for gestational age white singleton infants enrolled in the Fels Longitudinal Study. Odds ratios (OR) for overweight and obesity in young adulthood (age 20-29) were calculated using logistic regression models for the metrics at each target age (0, 1, 3, 6, 9, 12, 18, 24 months) comparing ≥85(th) v. <85(th) percentile, as well as rapid growth (Δ≥0.67 Z-score) through target age intervals. Models accounted for both maternal and paternal BMI. RESULTS Infants ≥85(th) percentile of weight-for-age at each target age (except 3 months) had a greater odds of being overweight as a young adult. After accounting for length (weight-for-length) this association was limited to 12, and 18 months. Rapid weight-for-age growth was infrequently associated with overweight as a young adult. Rapid weight-for-length growth from 0 to 24 months, 1 to 6, 9, 12, 18, and 24 months and from 3 to 9, 12, 18, and 24 months was strongly associated with overweight status as a young adult. CONCLUSIONS The WHO weight-for-length metric associates differently with risk of being overweight as a young adult compared to weight-for-age. Intervals of rapid weight-for-length growth ranging from months (0-24), (1-12, 18, and 24) and (3-9, and 12) displayed the largest OR for being overweight as a young adult.

Abstract
Obesity has now emerged as 1 of the most serious public health problems facing American Indian (AI) children and adolescents. However, little is known about what factors contribute to the early development of obesity in AI children. This study explored the relationships between maternal prepregnancy BMI, feeding practices, and growth in AI infants. The findings of this study highlight the need for nurse midwives and pediatric nurse practitioners to increase AI mothers' awareness about their feeding practices, exclusive breastfeeding, and timing for solid food introduction.

Abstract
Concerns about the increasing rates of obesity in developing countries have led many policy makers to question the impacts of maternal and early child nutrition on risk of later obesity. The purposes of the review are to summarise the studies on the associations between nutrition during pregnancy and infant feeding practices with later obesity from childhood through adulthood and to identify potential ways for preventing obesity in developing countries. As few studies were identified in developing countries, key studies in developed countries were included in the review. Poor prenatal dietary intakes of energy, protein and micronutrients were shown to be associated with increased risk of adult obesity in offspring. Female offspring seem to be more vulnerable than male offspring when their mothers receive insufficient energy during pregnancy. By influencing birthweight, optimal prenatal nutrition might reduce the risk of obesity in adults. While normal birthweights (2500-3999 g) were associated with higher body mass index (BMI) as adults, they generally were associated with higher fat-free mass and lower fat mass compared with low birthweights (<2500 g). Low birthweight was associated with higher risk of metabolic syndrome and central obesity in adults. Breastfeeding and timely introduction of complementary foods were shown to protect against obesity later in life in observational studies. High-protein intake during early childhood however was associated with higher body fat mass and obesity in adulthood. In developed countries, increased weight gain during the first 2 years of life was associated with a higher BMI in adulthood. However, recent studies in developing countries showed that higher BMI was more related to greater lean body mass than fat mass. It appears that increased length at 2 years of age was positively associated with height, weight and fat-free mass, and was only weakly associated with fat mass. The protective associations between breastfeeding and obesity may differ in developing countries compared to developed countries because many studies in developed countries used formula feeding as a control. Future research on the relationship between breastfeeding, timely introduction of complementary feeding or rapid weight gain and obesity are warranted in developing countries. The focus of interventions to reduce risk of obesity in later life in developing countries could include: improving maternal nutritional status during pregnancy to reduce low birthweight; enhancing breastfeeding (including durations of exclusive and total breastfeeding); timely introduction of high-quality complementary foods (containing micronutrients and essential fats) but not excessive in protein; further evidence is needed to understand the extent of weight gain and length gain during early childhood are related to body composition in later life.

Abstract
UNLABELLED Excess weight gain during both pre- and postnatal life increases risk for obesity in later life. Although a number of gestational and early life contributors to this effect have been identified, there is a dearth of research to examine whether gestational factors and weight gain velocity in infancy exert independent effects on subsequent body composition and fat distribution. OBJECTIVE To test the hypothesis that birth weight, as a proxy of prenatal weight gain, and rate of weight gain before 6 months would be associated with total and truncal adiposity at 12 months of age. DESIGN AND METHODS Healthy, term infants (N = 47) were enrolled in the study and rate of weight gain (g/day) was assessed at 0-3 months, 3-6 months, and 6-12 months. RESULTS Total and regional body composition were measured by dual-energy X-ray absorptiometry (DXA) at 12 months. Stepwise linear regression modeling indicated that lean mass at 12 months, after adjusting for child length, was predicted by rate of weight gain during each discrete period of infancy (P < 0.05), and by maternal pre-pregnancy BMI (P < 0.05). Total fat mass at 12 months was predicted by rate of weight gain during each discrete period (P < 0.01), and by older maternal age at delivery (P < 0.05). Trunk fat mass at 12 months, after adjusting for leg fat mass, was predicted by rate of weight gain from 0-3 months and 3-6 months (P < 0.05). CONCLUSION Results suggest that growth during early infancy may be a critical predictor of subsequent body composition and truncal fat distribution.

Abstract
The adoption of health behaviors characterized by minimal energy expenditure and overconsumption of energy has led to cardiometabolic risk factors in pregnancy, childhood, and youth, all of which increase the prevalence of cardiovascular disease in adulthood. The propensity to develop abdominal obesity and cardiometabolic risk factors appears to disproportionally affect non-white ethnic groups. While the majority of observational research has been conducted in populations of European origin, studies in non-white ethnic groups across the life-course are underway and there is evidence that unique ethnic-specific differences exist. This review will focus on the life-course determinants of obesity and its related cardio-metabolic risk factors among diverse ethnic groups including people of Afro-Caribbean origin, South Asian, East Asian, and indigenous ancestry.

Abstract
OBJETIVO: Avaliar se a mudança no escore Z do índice de massa corpórea por idade >0,67 no primeiro ano de vida se associou ao excesso de peso na idade pré-escolar. MÉTODOS: Estudo de coorte aninhado a ensaio de campo randomizado realizado na cidade de São Leopoldo, no Rio Grande do Sul. Foram coletados dados de peso e estatura das crianças ao nascimento, dos seis aos oito meses e dos 12 aos 16 meses. Aos três e aos quatro anos, além destes dados aferiu-se a circunferência da cintura. Calculou-se o ganho de peso pela diferença no escore Z do índice de massa corpórea/idade dos 12 até os 16 meses em relação ao índice de massa corpórea/idade ao nascimento, adotando-se ponto de corte >0,67 para ganho de peso excessivo. A relação cintura/estatura foi realizada, considerando-se excesso de adiposidade central se valores >0,5. Utilizou-se a análise multivariada para o teste da associação entre os desfechos e as variáveis independentes. RESULTADOS: A prevalência do ganho de peso excessivo no primeiro ano de vida foi de 29,5% de um total de 338 crianças. Após ajuste para as variáveis sexo, grupo, peso ao nascer, tempo de aleitamento materno exclusivo e índice de massa corpórea da mãe, a mudança no escore Z >0,67 do nascimento até os 12 a 16 meses apresentou-se como fator de risco para o excesso de peso (RR 2,81; IC95% 1,53-5,16) e elevada relação cintura/altura na idade pré-escolar (RR 2,10; IC95% 1,19-3,72). CONCLUSÕES: O ganho de peso excessivo no primeiro ano de vida está associado ao excesso de peso e à elevada adiposidade abdominal na idade pré-escolar.

Abstract
PURPOSE Early growth patterns have been associated with subsequent obesity risk. However, findings from middle-income populations suggest that early infant growth may benefit lean mass and height rather than adiposity. We tested the hypothesis that rapid weight or length gain in different growth periods would be associated with size and body composition in adolescence, in a prospective birth cohort from southern Brazil. METHODS Body composition was assessed in 425 adolescents (52.2% male) at 14 years. Exposures were birth weight z-score and conditional growth in weight or length for the periods 0-6, 6-12 and 12-48 months. Differences in anthropometric and body composition outcomes between tertiles of growth in each period were tested by one-way analysis of variance. RESULTS Size at birth and conditional weight and length at 6 months were associated with later height. The effect of infant weight gain on lean mass was greater for males than females, and effect on fat mass greater for females than males. By early childhood, rapid weight gain generated relatively similar effects on both tissue masses in both sexes. Rapid length gain had stronger effects on outcomes in males than females at each time point, and benefited lean mass more than adiposity. All effects were substantially attenuated after adjusting for current height. Early weight gain was more important than length gain at influencing body composition outcomes in adolescence. CONCLUSIONS Rapid infant weight and length gains were primarily associated with larger size in adolescence rather than increased adiposity. From one year onwards, associations between rapid weight gain and fat and lean masses remained after adjustment for height.

Abstract
Currently, about 10% of infants have a weight for length greater than the 95th percentile for their age and sex, which puts them at risk for obesity as they grow. In a pilot obesity prevention study, primiparous mothers and their newborn infants were randomly assigned to a control group or a Soothe/Sleep intervention. Previously, it has been demonstrated that this intervention contributed to lower weight-for-length percentiles at 1 year; the aim of the present study was to examine infant behavior diary data collected during the intervention. Markov modeling was used to characterize infants' patterns of behavioral transitions at ages 3 and 16 weeks. Results showed that heavier mothers were more likely to follow their infants' fussing/crying episodes with a feeding. The intervention increased infants' likelihood of transitioning from a fussing/crying state to an awake/calm state. A shorter latency to feed in response to fussing/crying was associated with a higher subsequent weight status. This study provides preliminary evidence that infants' transitions out of fussing/crying are characterized by inter-individual differences, are modifiable, and are linked to weight outcomes, suggesting that they may be promising targets for early behavioral obesity interventions, and highlighting the methodology used in this study as an appropriate and innovative tool to assess the impact of such interventions.

Abstract
BACKGROUND Overweight is among the major challenging health risk factors. It has been claimed that birth weight, being a critical indicator of prenatal developmental conditions, is related to long-term overweight risk. In order to check this important assumption of developmental and preventive medicine, we performed a systematic review and comprehensive meta-analysis. METHODS AND FINDINGS Relevant studies published up to January 2011 that investigated the relation between birth weight and later risk of overweight were identified through literature searches using MEDLINE and EMBASE. For meta-analysis, 66 studies from 26 countries and five continents were identified to be eligible, including 643,902 persons aged 1 to 75 years. We constructed random-effects and fixed-effects models, performed subgroup-analyses, influence-analyses, assessed heterogeneity and publication bias, performed meta-regression analysis as well as analysis of confounder adjusted data. Meta-regression revealed a linear positive relationship between birth weight and later overweight risk (p<0.001). Low birth weight (<2,500 g) was found to be followed by a decreased risk of overweight (odds ratio (OR) =0.67; 95% confidence interval (CI) 0.59-0.76). High birth weight (>4,000 g) was associated with increased risk of overweight (OR=1.66; 95% CI 1.55-1.77). Results did not change significantly by using normal birth weight (2,500-4,000 g) as reference category (OR=0.73, 95% CI 0.63-0.84, and OR=1.60, 95% CI 1.45-1.77, respectively). Subgroup- and influence-analyses revealed no indication for bias/confounding. Adjusted estimates indicate a doubling of long-term overweight risk in high as compared to normal birth weight subjects (OR=1.96, 95% CI 1.43-2.67). CONCLUSIONS Findings demonstrate that low birth weight is followed by a decreased long-term risk of overweight, while high birth weight predisposes for later overweight. Preventing in-utero overnutrition, e.g., by avoiding maternal overnutrition, overweight and/or diabetes during pregnancy, might therefore be a promising strategy of genuine overweight prevention, globally.

Abstract
OBJECTIVES To investigate the critical period for overweight development during early childhood by examining growth trajectory and related sex differences. METHODS Using piecewise linear mixed models and logistic regression, we examined the effect of growth trajectory at different periods on overweight at age 4-5 by sex among 13,6 971 regularly followed children (mean: 12.2 times) during 2000-2005 in south China. RESULTS The high-body mass index (BMI) group (>top tertile of BMI Z score at age of 4-5 years) had faster growth rates of BMI, BMI Z score, weight and height than the low-BMI group in the first 3 months of life. Boys were more likely to be overweight [odds ratio (OR) = 2.0, 95% confidence interval: 1.5-2.7] than girls; the male high-BMI group had higher growth rates during the first 3 months than girls with high-BMI, independently of environmental factors. Those fast grown (in the upper tertile of growth rates in BMI and BMI Z score) in periods 0-3 months had relatively higher OR of at risk of overweight at age of 4-5 years than those in other periods. CONCLUSIONS Overweight risk develops during the first 3 months of life. Boys have an earlier peak in growth than girls, which may help explain why overweight is more prevalent in boys in China.

Abstract
Childhood obesity rates have reached epidemic proportions. Excessive weight gain in infancy is associated with persistence of elevated weight status and later obesity. In this review, we make the case that weight gain in the first 6 mo is especially predictive of later obesity risk due to the metabolic programming that can occur early postpartum. The current state of knowledge regarding the biological determinants of excess infant weight gain is reviewed, with particular focus on infant feeding choice. Potential mechanisms by which different feeding approaches may program the metabolic profile of the infant, causing the link between early weight gain and later obesity are proposed. These mechanisms are likely highly complex and involve synergistic interactions between endocrine effects and factors that alter the inflammatory and oxidative stress status of the infant. Gaps in current knowledge are highlighted. These include a lack of data describing 1) what type of infant body fat distribution may impart risk and 2) how maternal metabolic dysfunction (obesity and/or diabetes) may affect milk composition and exert downstream effects on infant metabolism. Improved understanding and management of these early postnatal determinants of childhood obesity may have great impact on reducing its prevalence.

Abstract
AIM To determine a possible relationship between migraine and body mass index. METHODS Migraine shows a wide spectrum of comorbidities, including cardiocerebral, vascular, psychiatric, metabolic, neurological as well as other pathologies. Recent researches suggest that obesity was significantly correlated with migraine frequency and disability in children, as well as in adult population studies. We reviewed data from the literature to clarify this possible relationship. RESULTS Translational and basic science research shows multiple areas of overlap between migraine pathophysiology and the central and peripheral pathways regulating feeding. Specifically, neurotransmittors such as serotonin, peptides such as orexin, and adipocytokines such as adiponectin and leptin have been suggested to have roles in both feeding and migraine. A relationship between migraine and body mass index exists, and therefore, interventions to modify body mass index may provide a useful treatment model for investigating whether modest weight loss reduces headache frequency and severity in obese migraineurs. CONCLUSION The effect of obesity and weight change on headache outcomes may have important implications for clinical care.

Abstract
Diet in early infancy has an impact on early growth and the formation of flavour preferences, as well as on later life health outcomes. Although breast milk is the preferred source of nutrition during infancy, more than half of American infants receive infant formula by the age of 4 months. As a group, formula-fed infants weigh more by the age of one year and have a greater risk for later obesity than breastfed infants. However, a recent randomized study found that, when compared to breastfed infants, infants fed an extensively hydrolysed protein formula (ePHF) had more normative weight gain velocity than infants fed cow's milk formula (CMF). Therefore, grouping all formula-fed infants together with respect to certain health outcomes such as obesity may not be appropriate. Scientific evidence also suggests that there are sensitive periods for flavour learning. Infants become familiar with and learn to accept the flavours they experience through their mother's amniotic fluid and breast milk as well as formula. These early experiences influence flavour preferences of children that may affect food choices and therefore later life health. Further research on the influence of early diet on growth, flavour preferences, and food choices is imperative.

Abstract
The consequences of fetal growth retardation remain unclear, in part because they appear to vary between industrialized and developing countries. Data on body composition offer a new opportunity to investigate this issue, and may be of particular value in addressing the controversial role of nutrition in infancy, which has been proposed by some to boost survival, and by others to increase long-term risk of chronic diseases. The uncertainty regarding the effects of post-natal nutrition is presenting challenges to nutritional policy as many countries undergo the nutrition transition, whereby the nutritional status of individuals may shift within the life-course. A theoretical model, building on the thrifty phenotype hypothesis, is presented to clarify how body composition data can address this dilemma. Measurements of body composition can now be obtained in infants and children using several different technologies, indicating that large-scale studies can now be conducted to investigate objectively the association between early growth patterns and later health.

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.

Abstract
The purpose of this review was to evaluate factors in early childhood (≤5 years of age) that are the most significant predictors of the development of obesity in adulthood. Factors of interest included exposures/insults in the prenatal period, infancy and early childhood, as well as other socio-demographic variables such as socioeconomic status (SES) or birth place that could impact all three time periods. An extensive electronic and systematic search initially resulted in 8,880 citations, after duplicates were removed. Specific inclusion and exclusion criteria were set, and following two screening processes, 135 studies were retained for detailed abstraction and analysis. A total of 42 variables were associated with obesity in adulthood; however, of these, only seven variables may be considered as potential early markers of obesity based on the reported associations. Possible early markers of obesity included maternal smoking and maternal weight gain during pregnancy. Probable early markers of obesity included maternal body mass index, childhood growth patterns (early rapid growth and early adiposity rebound), childhood obesity and father's employment (a proxy measure for SES in many studies). Health promotion programmes/agencies should consider these factors as reasonable targets to reduce the risk of adult obesity.

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
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
The concept that environmental stimuli imparted on a developing organism have the potential to affect both its short- and long-term developmental profiles is intuitively appealing and, more importantly, supported by a growing body of experimental and observational evidence. A number of groups have posited model hypotheses in tandem with experimental data, linking extrinsic factors to the development of a host of human diseases. Here, we review the evolution of 'the developmental origins of health and disease' as a concept and discuss recent advances in the association of specific stimuli to obesity, an epidemic cause of human morbidity and mortality.

Abstract
Eliminating racial/ethnic disparities in health and health care is a national priority, and obesity is a prime target. During the last 30 y in the United States, the prevalence of obesity among children has dramatically increased, sparing no age group. Obesity in childhood is associated with adverse cardio-metabolic outcomes such as hypertension, hyperlipidemia, and type II diabetes and with other long-term adverse outcomes, including both physical and psychosocial consequences. By the preschool years, racial/ethnic disparities in obesity prevalence are already present, suggesting that disparities in childhood obesity prevalence have their origins in the earliest stages of life. Several risk factors during pregnancy are associated with increased risk of offspring obesity, including excessive maternal gestational weight gain, gestational diabetes, smoking during pregnancy, antenatal depression, and biological stress. During infancy and early childhood, rapid infant weight gain, infant feeding practices, sleep duration, child's diet, physical activity, and sedentary practices are associated with the development of obesity. Studies have found substantial racial/ethnic differences in many of these early life risk factors for childhood obesity. It is possible that racial/ethnic differences in early life risk factors for obesity might contribute to the high prevalence of obesity among minority preschool-age children and beyond. Understanding these differences may help inform the design of clinical and public health interventions and policies to reduce the prevalence of childhood obesity and eliminate disparities among racial/ethnic minority 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
The stability of eating patterns from infancy through childhood is largely unknown. This study identified subgroups of children based on emergent eating patterns from ages 1 to 3 years and examined differences between groups in demographic, anthropometric and temperamental variables. We conducted secondary analyses of 262 boys and 225 girls from the Colorado Adoption Project. Three eating styles (Reactivity to Food, Predictable Appetite, Distractibility at Mealtime) and five temperaments were assessed at ages 1 and 3 years. Weight and height (length) were assessed on children and mothers. Correlations examined the stability of eating patterns, cluster analysis identified subgroups of emergent eating styles, and analysis of variance identified variables differentiating the derived subgroups. Eating styles were moderately stable over time, although all increased on average. Four subgroups were identified: Diet Expanding and Preference Establishing Eaters (37%), Emerging Reactive Tendency Eaters (23%), Emerging Food-Indifferent and Non-Fussy Eaters (31%), and Emerging High-Reactive and Fussy Eaters (9%). The subgroups differed in year 1 Wt/L and Reaction to Food, and year 1-to-3 changes in Emotionality and Reaction to Food. Four emergent eating patterns were identified. How these subgroups of children differ in later weight and health trajectories warrants research.

Abstract
Birth weight has been inversely associated with later blood pressure. Firstborns tend to have lower birth weight than their later-born peers, but the long-term consequences remain unclear. The study objective was to investigate differences between firstborn and later-born individuals in early growth patterns, body composition, and blood pressure in Brazilian adolescents. The authors studied 453 adolescents aged 13.3 years from the prospective 1993 Pelotas Birth Cohort. Anthropometry, blood pressure, physical activity by accelerometry, and body composition by deuterium were measured. Firstborns (n = 143) had significantly lower birth weight than later borns (n = 310). At 4 years, firstborns had significantly greater weight and height, indicating a substantial overshoot in catch-up growth. In adolescence, firstborns had significantly greater height and blood pressure and a lower activity level. The difference in systolic blood pressure could be attributed to variability in early growth and that in diastolic blood pressure to reduced physical activity. The magnitude of increased blood pressure is clinically significant; hence, birth order is an important developmental predictor of cardiovascular risk in this population. Firstborns may be more sensitive to environmental factors that promote catch-up growth, and this information could potentially be used in nutritional management to prevent catch-up “overshoot.”

Abstract
Reference %fat and total fat-free mass data is necessary for evaluating growth in infants. We aimed to develop longitudinal %fat and total fat-free mass data in infants from birth to 6 months of age. An observational, multicenter, prospective cohort study was conducted with assessments at birth, 1 week, 2 weeks, 1, 2, 3, 4, 5, and 6 months of age. Subjects were exclusively breast-fed and were enrolled at three centers. Whole-body composition (i.e., % fat and total fat-free mass) were assessed using air-displacement plethysmography (ADP) (PEA POD; Life Measurement, Concord, CA). Maternal prepregnancy BMI, gestational weight gain, and infant anthropometric data were collected. A total of 160 infants (boys = 84) were assessed from birth to 4 months of age. Mean birth weight was 3.46 ± 0.39 kg % fat and fat-free mass significantly increased from birth to 4 months of age (P < 0.0001). Gender-specific %fat and total fat-free mass curves for infants from birth to 4 months of age were created. This study will be beneficial to health-care professionals in evaluating normal growth and nutritional patterns in the first months of life.

Abstract
OBJECTIVE Rapid economic development and subsequent changes in lifestyle and disease burdens ('health transition') is associated with increasing prevalence of obesity among both adults and children. However, because of continued infectious diseases and undernutrition during the early stages of transition, monitoring childhood obesity has not been prioritized in many countries and the scope of the problem is unknown. Therefore we sought to characterize patterns of childhood overweight and obesity in an early transitional area, the South Pacific archipelago of Vanuatu. DESIGN We completed an anthropometric survey among children from three islands with varying levels of economic development, from rural areas (where adult obesity prevalence is low) to urban areas (where adult obesity prevalence is high). SETTING The islands of Ambae (rural), Aneityum (rural with tourism) and Efate (urban). SUBJECTS Boys and girls (n 513) aged 6-17 years. RESULTS Height-, weight- and BMI-for-age did not vary among islands, and prevalence of overweight/obesity based on BMI was low. However, girls from Aneityum - a rural island where the tourism industry increased rapidly after malaria eradication - had increased central adiposity compared with girls from the other islands. This is contrary to adult patterns, which indicate higher obesity prevalence in urban areas. Multiple factors might contribute, including stunting, biological responses after malaria control, sleeping patterns, diet and physical activity levels. CONCLUSIONS Measures of central adiposity highlight an emerging obesity risk among girls in Vanuatu. The data highlight the synergistic relationship among infectious diseases, undernutrition and obesity during the early stages of health transition.

Abstract
Several Canadian professional organizations recently recommended that the growth of preterm infants be monitored using the World Health Organization Growth Standards (WHO-GS) after hospital discharge. The WHO-GS are a prescriptive set of growth charts that describe how term infants should grow under ideal environmental conditions. Whether preterm infants following this pattern of growth have better outcomes than infants that do not has yet to be evaluated. Our aim was to determine whether the pattern of growth of very low birth weight (VLBW) infants during the first 2 years, assessed using the WHO-GS or the traditional Centers for Disease Control and Prevention reference growth charts (CDC-RGC), is associated with neurodevelopment. Pattern of weight, length, and head circumference gain of appropriate-for-gestation VLBW preterm infants (n = 289) from birth to 18–24 months corrected age was classified, using the WHO-GS and CDC-RGC, as sustained (change in Z-score ≤1 SD), decelerated (decline >1 SD), or accelerated (incline >1 SD). Development was assessed using the Bayley Scales of Infant and Toddler Development (BSID)-III at 18–24 months corrected age. Using the WHO-GS, children with a decelerated pattern of weight gain had lower cognitive (10 points), language (6 points), and motor (4 points) scores than infants with sustained weight gain (p < 0.05), even after adjustment for morbidities. No association was found using the CDC-RGC. In conclusion, a decelerated pattern of weight gain, determined with the WHO-GS, but not the CDC-GRC, is associated with poorer neurodevelopment scores on the BSID-III than a pattern of sustained growth.

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
The scientific study of obesity has been dominated throughout the twentieth century by the concept of energy balance. This conceptual approach, based on fundamental thermodynamic principles, states that energy cannot be destroyed, and can only be gained, lost or stored by an organism. Its application in obesity research has emphasised excessive appetite (gluttony), or insufficient physical activity (sloth), as the primary determinants of excess weight gain, reflected in current guidelines for obesity prevention and treatment. This model cannot explain why weight accumulates persistently rather than reaching a plateau, and underplays the effect of variability in dietary constituents on energy and intermediary metabolism. An alternative model emphasises the capacity of fructose and fructose-derived sweeteners (sucrose, high-fructose corn syrup) to perturb cellular metabolism via modification of the adenosine monophosphate (AMP)/adenosine triphosphate (ATP) ratio, activation of AMP kinase and compensatory mechanisms, which favour adipose tissue accretion and increased appetite while depressing physical activity. This conceptual model implicates chronic hyperinsulinaemia in the presence of a paradoxical state of 'cellular starvation' as a key driver of the metabolic modifications inducing chronic weight gain. We combine evidence from in vitro and in vivo experiments to formulate a perspective on obesity aetiology that emphasises metabolic flexibility and dietary composition rather than energy balance. Using this model, we question the direction of causation of reported associations between obesity and sleep duration or childhood growth. Our perspective generates new hypotheses, which can be tested to improve our understanding of the current obesity epidemic, and to identify novel strategies for prevention or treatment.

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.

Abstract
PURPOSE To specifically examine infant feeding practices in a sample of young mothers. STUDY DESIGN AND METHODS A cross-sectional, descriptive/exploratory design with author-developed measures was used to assess maternal demographics, and knowledge of and practices related to infant (6-12 months of age) feeding. RESULTS Numerous inappropriate feeding practices were identified in this sample of predominately low-income, African American young mothers (n = 67). More than half (52%) of the mothers had a BMI ≥ 25, with 27% having a BMI ≥ 30. Most mothers attempted to breastfeed (53%), but only 25% breastfed beyond 6 months. Inappropriate food choices for infants (such as french fries), practices such as putting cereal in their babies' bottles (82%), and starting solid foods before 6 months of age (64%) were reported. In this study, a shift from a balanced diet including adequate fruits and vegetables toward less nutrient-dense foods occurred when infants were approximately 7 to 9 months of age. CLINICAL IMPLICATIONS Most mothers in this study were overweight themselves, and had initiated less than optimal feeding practices in their young children. Given the identified relationship between a mother's diet and her infant's diet over time, it is clear that nurses should consider developing interventions to both promote early healthy infant feeding practices and assist young mothers to improve their nutrition simultaneously. Nurses can also target grandmothers and other family members who provide infant care in attempting to improve family nutrition.

Impact of birth weight and early infant weight gain on insulin resistance and associated cardiovascular risk factors in adolescence. PLoS One 2011; 6:e20595. [PMID: 21655104 PMCID: PMC3107215 DOI: 10.1371/journal.pone.0020595] [Citation(s) in RCA: 107] [Impact Index Per Article: 8.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2011] [Accepted: 05/05/2011] [Indexed: 02/06/2023] Open
Abstract
Background Low birth weight followed by accelerated weight gain during early childhood has been associated with adverse metabolic and cardiovascular outcomes later in life. The aim of this study was to examine the impact of early infant weight gain on glucose metabolism and cardiovascular risk factors in adolescence and to study if the effect differed between adolescents born small for gestational age (SGA) vs. appropriate for gestational age (AGA). Methodology/Principal Findings Data from 30 SGA and 57 AGA healthy young Danish adolescents were analysed. They had a mean age of 17.6 years and all were born at term. Data on early infant weight gain from birth to three months as well as from birth to one year were available in the majority of subjects. In adolescence, glucose metabolism was assessed by a simplified intravenous glucose tolerance test and body composition was assessed by dual-energy X-ray absorptiometry. Blood pressures as well as plasma concentrations of triglycerides and cholesterol were measured. Early infant weight gain from birth to three months was positively associated with the fasting insulin concentration, HOMA-IR, basal lipid levels and systolic blood pressure at 17 years. There was a differential effect of postnatal weight gain on HOMA-IR in AGA and SGA participants (P for interaction = 0.03). No significant associations were seen between postnatal weight gain and body composition or parameters of glucose metabolism assessed by the simplified intravenous glucose tolerance test. In subgroup analysis, all associations with early infant weight gain were absent in the AGA group, but the associations with basal insulin and HOMA-IR were still present in the SGA group. Conclusion This study suggests that accelerated growth during the first three months of life may confer an increased risk of later metabolic disturbances – particularly of glucose metabolism – in individuals born SGA.
