Abstract
Background Given the rapid development during the early years (0-4 years), an understanding of the health implications of physical activity is needed. The purpose of this systematic review was to examine the relationships between objectively and subjectively measured physical activity and health indicators in the early years. Methods Electronic databases were originally searched in April, 2016. Included studies needed to be peer-reviewed, written in English or French, and meet a priori study criteria. The population was apparently healthy children aged 1 month to 59.99 months/4.99 years. The intervention/exposure was objectively and subjectively measured physical activity. The comparator was various volumes, durations, frequencies, patterns, types, and intensities of physical activity. The outcomes were health indicators ranked as critical (adiposity, motor development, psychosocial health, cognitive development, fitness) and important (bone and skeletal health, cardiometabolic health, and risks/harm). The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) framework was used to assess the quality of evidence for each health indicator by each study design. Results Ninety-six studies representing 71,291 unique participants from 36 countries were included. Physical activity interventions were consistently (>60% of studies) associated with improved motor and cognitive development, and psychosocial and cardiometabolic health. Across observational studies, physical activity was consistently associated with favourable motor development, fitness, and bone and skeletal health. For intensity, light- and moderate-intensity physical activity were not consistently associated with any health indicators, whereas moderate- to vigorous-intensity, vigorous-intensity, and total physical activity were consistently favourably associated with multiple health indicators. Across study designs, consistent favourable associations with health indicators were observed for a variety of types of physical activity, including active play, aerobic, dance, prone position (infants; ≤1 year), and structured/organized. Apart from ≥30 min/day of the prone position for infants, the most favourable frequency and duration of physical activity was unclear. However, more physical activity appeared better for health. Evidence ranged from “very low” to “high” quality. Conclusions Specific types of physical activity, total physical activity, and physical activity of at least moderate- to vigorous-intensity were consistently favourably associated with multiple health indicators. The majority of evidence was in preschool-aged children (3-4 years). Findings will inform evidence-based guidelines.

Abstract
Objective To determine whether gestational weight gain (GWG) was associated with increased odds of childhood overweight after accounting for pre-pregnancy BMI. Methods In a prospective cohort study based on a premarital and perinatal health care system in China, data of 100 612 mother-child pairs were obtained. The main exposure was GWG as both a continuous and categorical variable. The outcome measure was overweight, defined by age- and sex-specific cutoff values for body mass index (BMI) in children aged 3–6 years. Results A 1-kg increase in maternal GWG was associated with an increase of 0.009 (95% confidence interval [CI]: 0.007–0.010, P < 0.001) in children’s mean BMI; in the subgroup of pre-pregnancy overweight/obese mothers, the increase in children’s BMI was 0.028 (95% CI, 0.017–0.039, P < 0.001). Excessive GWG played an important role in childhood overweight when adequate GWG was used as the reference, with an odds ratio (OR) of 1.21 (95% CI, 1.12–1.29). The risk was highest (OR 2.22; 95% CI, 1.79–2.76) in the children of mothers who were overweight/obese before pregnancy and gained excessive weight during pregnancy. Conclusions Greater maternal GWG was associated with greater offspring BMI, and the risk of overweight was doubled in children whose mothers were overweight/obese before pregnancy and gained excessive weight during pregnancy. As a result, maintenance of appropriate weight gain during pregnancy and prophylaxis of maternal overweight/obesity before pregnancy should be a strategy for preventing childhood overweight/obesity.

Abstract
BACKGROUND Accurate early assessment and targeted intervention with problematic parent/child feeding dynamics is critical for the prevention and treatment of child obesity. The division of responsibility in feeding (sDOR), articulated by the Satter Feeding Dynamics Model (fdSatter), has been demonstrated clinically as an effective approach to reduce child feeding problems, including those leading to obesity. Lack of a tested instrument to examine adherence to fdSatter stimulated initial construction of the Satter Feeding Dynamics Inventory (fdSI). The aim of this project was to refine the item pool to establish translational validity, making the fdSI suitable for advanced psychometric analysis. METHODS Cognitive interviews (n = 80) with caregivers of varied socioeconomic strata informed revisions that demonstrated face and content validity. fdSI responses were mapped to interviews using an iterative, multi-phase thematic approach to provide an instrument ready for construct validation. RESULTS fdSI development required five interview phases over 32 months: Foundational; Refinement; Transitional; Assurance; and Launching. Each phase was associated with item reduction and revision. Thirteen items were removed from the 38-item Foundational phase and seven were revised in the Refinement phase. Revisions, deletions, and additions prompted by Transitional and Assurance phase interviews resulted in the 15-item Launching phase fdSI. Only one Foundational phase item was carried through all development phases, emphasizing the need to test for item comprehension and interpretation before psychometric analyses. CONCLUSIONS Psychometric studies of item pools without encrypted meanings will facilitate progress toward a tool that accurately detects adherence to sDOR. Ability to measure sDOR will facilitate focus on feeding behaviors associated with reduced risk of childhood obesity.

Abstract
The early years represent a critical period for promoting physical activity. However, the amount of physical activity needed for healthy growth and development is not clear. Using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) framework, we aimed to present the best available evidence to determine the relationship between physical activity and measures of adiposity, bone and skeletal health, motor skill development, psychosocial health, cognitive development, and cardiometabolic health indicators in infants (1 month – 1 year), toddlers (1.1–3.0 years), and preschoolers (3.1–4.9 years). Online databases, personal libraries, and government documents were searched for relevant studies. Twenty-two articles, representing 18 unique studies and 12 742 enrolled participants, met inclusion criteria. The health indicators of interest were adiposity (n = 11), bone and skeletal health (n = 2), motor development (n = 4), psychosocial health (n = 3), cognitive development (n = 1), and cardiometabolic health indicators (n = 3); these indicators were pre-specified by an expert panel. Five unique studies involved infants, 2 involved toddlers, and 11 involved preschoolers. In infants, there was low- to moderate-quality evidence to suggest that increased or higher physical activity was positively associated with improved measures of adiposity, motor skill development, and cognitive development. In toddlers, there was moderate-quality evidence to suggest that increased or higher physical activity was positively associated with bone and skeletal health. In preschoolers, there was low- to high-quality evidence on the relationship between increased or higher physical activity and improved measures of adiposity, motor skill development, psychosocial health, and cardiometabolic health indicators. There was no serious inconsistency in any of the studies reviewed. This evidence can help to inform public health guidelines. (PROSPERO registration: CRD42011001243)

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
Insufficient sleep may lead to adverse health effects, influencing body weight. This study quantified the prevalence of short sleep and the association between sleep duration and overweight in a sample of suburban students. Cross-sectional study was conducted in 2004, involving 529 students from Bay High School, Bay Village, OH, USA, using self-administered questionnaires assessing lifestyle and sleep behaviors. Students with a body mass index Z Score >85th percentile for sex and age were deemed overweight. Ninety percent of students reported average sleep time less than 8 h on school nights, with 19% reported less than 6 h of sleep per night. Twenty percent of the sample were overweight. Overweight was significantly associated with the male gender, increased caffeine consumption, and short sleep duration. Compared with students sleeping >8 h, the age and gender-adjusted odds ratio of overweight was 8.53 (95% CI: 2.26, 32.14) for those with <5 h sleep (P = 0.0036); 2.79 (1.03, 7.55) for those with 5-6 h sleep; 2.81 (1.14, 6.91) for those with 6-7 h sleep; and 1.29 (0.52, 3.26) for those with 7-8 h sleep. Short sleep duration was common and associated with overweight with evidence of a "dose-response" relationship. These results confirm a high prevalence of short sleep among suburban high school students and provide additional support suggesting significant association between short sleeping hours and overweight.

Abstract
BACKGROUND Despite the high prevalence of overweight among Hispanic children in the United States, definitive predictors of weight gain have not been identified in this population. OBJECTIVE The study objective was to test sociodemographic, metabolic, and behavioral predictors of 1-y weight gains in a large cohort of Hispanic children studied longitudinally. DESIGN Subjects (n = 879) were siblings from 319 Hispanic families enrolled in the Viva la Familia Study. Families were required to have at least one overweight child aged 4-19 y. One-year changes in weight and body composition by dual-energy X-ray absorptiometry were measured. Data were from parental interviews, birth certificates, multiple-pass 24-h dietary recalls, 3-d accelerometry, 24-h respiration calorimetry, measurements of eating in the absence of hunger, and measurement of fasting blood biochemistry indexes by radioimmunoassay. Generalized estimating equations and principal component analysis were applied. RESULTS Weight gain increased with age (P = 0.001), peaking at approximately 10 y of age in girls and approximately 11 y of age in boys. Mean (+/-SD) weight gain was significantly higher in overweight (7.5 +/- 3.7 kg/y) than in nonoverweight (4.4 +/- 2.4 kg/y) children and in boys than in girls. When adjusted for age, age squared, sex, and Tanner stage, the final model indicated a child's body mass index (BMI; kg/m2) status, maternal BMI, energy expenditure (total energy expenditure, basal metabolic rate, and sleeping metabolic rate), and fasting blood biochemistry indexes (total triiodothyronine, insulin, leptin, and ghrelin) as independent, positive predictors of weight gain (P = 0.01-0.001). CONCLUSION Knowledge of the metabolic and behavioral predictors of weight gain in Hispanic children will inform prevention and treatment efforts to address this serious public health problem in the United States.

Abstract
UNLABELLED In a systematic review, we identified 21 separate studies with data on the association between rapid infancy weight gain, up to age 2 y, and subsequent obesity risk. Uniformly all studies reported significant positive associations. We transformed the reported effect sizes to a standard infancy weight gain exposure, and found that further differences in study design accounted for much of the variation in risk. An accompanying paper by Melinda Yeung reminds us that there are benefits of postnatal catch-up growth in certain populations, and suggests that genetic and nutritional factors could moderate the unhealthy translation of rapid infancy weight gain to visceral fat and insulin resistance. Further evidence is needed, and we will need to rigorously test the benefits and risks of any interventions. However, the concept of "healthy" rapid catch-up infancy growth is an attractive prospect. CONCLUSION Rapid infancy weight gain is consistently associated with increased subsequent obesity risk, but the predictive ability of different weight gain cut-offs needs to be tested.

Abstract
OBJECTIVES To compare the prevalence of overweight among young children of different ethnic backgrounds and describe the age pattern of overweight in early childhood. METHODS Cross-sectional study of 21,911 children, 12 to 59 months old, participating in the Hawaii Special Supplemental Nutrition Program for Women, Infants, and Children in 1997-1998. They were grouped in eight ethnic categories. For 1-year-olds we defined overweight as weight-for-age at the 95th percentile or more and underweight as weight-for-age at less than the 10th percentile. For 2- to 4-year-olds overweight was defined as body mass index (BMI) at the 95th percentile or more, underweight as BMI less than 10th percentile, tall stature as height-for-age at the 95th percentile or more, and short stature as height-for-age at less than the 10th percentile. The National Center for Health Statistics 2000 growth charts were the reference values. The analysis included bivariate and multivariate methods. RESULTS Large differences were found among ethnic groups. Among 1-year-olds, Samoans were the heaviest (17.5% overweight) and Filipinos the lightest (30.2% underweight). Among 2- to 4-year-olds, Samoans were the heaviest (27.0% overweight) and the tallest (16.9% tall), whereas Asians were the lightest (12.2% underweight), and Filipinos the shortest (19.0% short). Hawaiians and Asians also had a high percentage of short children (13.6% and 12.2%, respectively). Prevalence of overweight in all 2- to 4-year-olds was more than the expected 5%, especially for Samoans, Filipinos, Hawaiians, and Asians. At age 2 to 4 years, overweight was almost twice as prevalent as at age 1. Multivariate analysis showed that ethnicity (Samoan) had the strongest independent association with weight-for-age percentile, BMI, and overweight in the two age groups, followed by birth weight. CONCLUSIONS This is the first study of overweight among children of Asian and Pacific Island backgrounds in Hawaii. It identified important characteristics of growth and will be helpful in the design of appropriate activities to prevent overweight.

Abstract
BACKGROUND The aim of the present study was to elucidate both environmental and behavioral factors that influence body mass index (BMI, kg/m2) among Japanese children from ages 3-6. METHODS In 1992 (at age 3) and 1995 (at age 6), 8170 6-year-old children (4176 boys and 3994 girls) were surveyed using a questionnaire on both body build (height and weight) and lifestyle. The correlation between BMI for 3-year-olds and for 6-year-olds were analyzed. From the temporal changes of body build between age 3 and 6 years, we categorized children into four groups: group 1, normal at both age 3 years and 6 years (normal/normal); group 2, overweight at age 3 years and normal at age 6 years (overweight/normal); group 3, normal at age 3 years and overweight at age 6 years (normal/overweight); and group 4, overweight at both age 3 years and 6 years (overweight/overweight). The authors compared the four groups with each other according to sex, concerning frequencies of children who matched the categories of environmental and behavioral factors. Each factor was tested using the chi2 test. Overweight children were defined as those whose BMI value was age-sex specific in the 90th percentile or more. RESULTS A significant correlation was found between body builds for children aged 3 and 6 years in both genders (boys, r = 0.559, P < 0.01; girls, r = 0.584, P < 0.01). Significant factors associated with overweight children were diet (eating rice, green tea, eggs, meat, but less breads and juice), rapid eating, short sleep duration, early bedtime, long periods of television viewing, avoidance of physical activity, and frequent bowel movement. DISCUSSION Temporal changes in BMI from age 3 years to 6 years are significantly associated with both environmental and behavioral factors at age 6 years. The results of this study may be useful for health promotion programs designed to prevent obesity during the early stages of childhood.

Abstract
Weight and height from infancy to age 15 years was studied in the Geelong population (n = 1200 in infancy; n = 213 at adolescence), Victoria, Australia. Body mass index (BMI) increased from 3 months to 12 months and then decreased again until 80 months after which it increased to 20.5 kg/m2 at the age of 15 years. The extent of tracking of BMI in infants classified as overweight or underweight was similar and differed from that of subjects of normal weight. Only one in four of the infants classified as overweight or underweight in infancy were still in the same category in adolescence, compared with three in four of those classified as of normal weight. Socioeconomic status has an effect on weight and height status in adolescence but not on the tracking of BMI. The age at 6-7 years is a critical age for weight and height status in adolescence. It appears that weight and height in infancy have a significant relationship with body size in adolescence but only in boys.

Abstract
BACKGROUND The relationship between activity levels and body fat in children is unclear, despite a large number of studies. The issue is clouded by the wide variety of methods used to assess children's activity levels. It is important to assess whether the type of activity measure influences the fatness-activity relationship. This is a first step to uncovering the role of modifying variables such as gender, age, maturity, etc. PRIMARY OBJECTIVE This study uses meta-analytic procedures to synthesize the results of such studies and to assess whether the type of activity measure used has an effect on the strength of the relationship observed. METHODS AND PROCEDURES Fifty studies were located that satisfied the inclusion criteria. Seventy-eight per cent of the studies showed a negative relationship, 18% no relationship and 4% a positive relationship between physical activity and body fatness. Data were analysed using the meta-analytic procedures described by Rosenthal (Meta-analytic Procedures for Social Research, Sage, 1991). MAIN OUTCOMES AND RESULTS The mean effect size indicated a small to moderate, inverse relationship (r = -0.16). Mean effect sizes differed significantly (F(3,52) = 8.04, p < 0.001) according to the activity measure used: questionnaire, r = -0.14; motion counters, r = -0.18; observation, r = -0.39; heart rate (HR), r = 0.00. Observation measures elicited a significantly stronger relationship with body fat than did questionnaire or heart rate measures (p < 0.05). However, there was no significant difference between the effect sizes elicited by observation and motion counters. Correlational analyses revealed no effect of age group or gender on the strength of the relationship between fatness and activity. CONCLUSIONS This meta-analysis suggests there is a small to moderate relationship between body fat and activity in children. It is important to note, however, that the size of the relationship depends on the activity measure used. It is therefore recommended that direct measures of movement, such as observation or motion counter methods, are used to assess the relationship of activity levels with health.

Abstract
Obesity is a risk factor for life-style-related diseases, and is based on three factors: genetic, environmental, and life-style. In adults, it is difficult to achieve and maintain normal body weight, so it is more effective to intervene from infancy to establish weight control. Legally required health checkups in infants of 18 and 36 months present important opportunities for obesity prevention. We consider genetic analysis to be a very important factor for obesity prevention in infancy. However, since health checkups don't involve the collection of blood, genetic analysis is considered difficult. In this study, we attempted the typing of beta3 adrenergic receptor gene polymorphism as a genetic factor from non-invasively obtained samples, buccal mucosa, hair and cerumen in 96 infants at their 18- and 36-month health checkups. Sampling buccal mucosa, hair and cerumen instead of blood caused almost no anxiety to the child or parent, so 94.1% cooperation with sampling was obtained. From buccal mucosa, about 76% of the samples could be used for the typing of polymorphism (81% by enzyme method, 59% by kit method). From hair, about 44% of the samples permitted typing of polymorphism, but from cerumen only about 4% of the samples could be used. Results from buccal mucosa and hair typed about 90% of infant polymorphism. These results suggest that this method would be practical at periodic health checkups, and would probably be applicable to mass screenings for genetic factor analysis for other diseases.

Abstract
OBJECTIVES Obesity may be a possible explanation for the higher cardiovascular disease mortality in Black women compared with White women. The National Heart, Lung, and Blood Institute Growth and Health Study (NGHS) is designed to assess factors associated with the development of obesity in Black and White preadolescent girls and its effects on major cardiovascular-disease risk factors. METHODS NGHS is a 5-year cohort study of 2379 girls, aged 9 through 10 years at entry. Anthropometry, blood pressure, and maturation staging are measured annually, and blood lipids biannually. Information on education, income, and family composition is also obtained from parents. RESULTS At baseline, compared with White girls, Black girls were slightly older, biologically more mature, taller, heavier, and had higher Quetelet Indices, skinfolds, and blood pressures. Black girls had lower triglycerides and higher HDL cholesterol than White girls. Total cholesterol and LDL cholesterol were similar in the two groups. CONCLUSIONS Baseline descriptive characteristics of the NGHS cohort showed that, in subjects aged 9 and 10 years, racial differences in obesity and blood pressure were already present.

Abstract
A prospective study of a cohort of healthy infants observed from birth to 2 years of age was carried out to investigate factors influencing the development of early adiposity. Infant suckling was measured in the laboratory twice during the first month of life. Multiple regression analyses revealed that parental educational level and a measure of feeding behavior, the interval between bursts of suckling, accounted for 18% of the variance in triceps skinfold measures at 1 year of age. A lower level of education and shorter interburst interval were associated with increased adiposity. Two feeding variables, pressure of suckling and the number of reported feeds per day, accounted for 21% of the variance in skinfold thickness at 2 years of age. Fewer, but larger, feeds and a higher sucking pressure were associated with a greater degree of adiposity. It seems that a vigorous infant feeding style, consisting of sucking more rapidly, at higher pressure, with a longer suck and burst duration, and a shorter interval between bursts of sucking, is associated with higher caloric intake and greater adiposity. The early development of this feeding style suggests that it may be a genetically endowed behavior. Breast-feeding protected against early adiposity only to the age of 6 months in this cohort of infants.

Abstract
The persistence of obesity and overweight over eight years was assessed in a biracial (Black-White) cohort of 1,490 two-to 14-year-olds. Initial levels of triceps skinfold thickness (TRSF) and Rohrer index (weight/height3) were moderately predictive of subsequent levels: r = 0.54 and 0.67, respectively. However, TRSF and Rohrer index tended to track most strongly in Black females (r = 0.64 and 0.72) and less well in both White females (r = 0.45 and 0.57) and preschool children (r = 0.45 and 0.54). Based on elevated levels of TRSF or Rohrer index, children were classified as obese or overweight, respectively. Of the 222 children who were initially above the 85th percentile for TRSF, 43 per cent remained obese after eight years. Persistence of overweight was slightly greater at follow-up, with 50 per cent of initially overweight children staying above the 85th percentile for Rohrer index. Severe, initial obesity/overweight (greater than 95th percentile) and consecutively elevated levels increased the probability of remaining obese/overweight. Results indicate that moderate, juvenile-onset obesity is malleable, but that the child who is extremely obese over consecutive examinations is likely to become an obese adult.

Abstract
The hypothesis that preweaning nutrition influences adult fat cell number and adiposity was tested in baboons. Newborn baboons were fed Similac formulas with caloric densities of 40.5 kcal (underfed), 67.5 kcal (fed normally), and 94.5 kcal (overfed) per 100 g formula. From weaning (16 wk) until necropsy at 5 yr of age all baboons were fed the same diet. At necropsy, fat cell number and fat cell size in 10 fat depots were measured. Female baboons overfed as infants had markedly greater fat depot mass, primarily because of fat cell hypertrophy, than normally fed or underfed females. Overfed male baboons had a greater fat mass in 4 of 10 depots compared with males underfed or fed normally as infants. Underfeeding did not affect body weight, nor adipose mass of either sex. The results show that infant food intake does not have a major influence on the fat cell number of young adult baboons.

Abstract
Diet and growth were studied prospectively in 78 boys ages 6 months to 14 years. All boys were well nourished and not grossly obese. Pubertal development was evaluated at age 14 years, and the results correlated with diet and early growth. No nutrients were significantly correlated with the stage of pubertal development. Boys with more advanced pubic hair development (Tanner greater than 3) and longer penile length (greater than or equal to 10 cm) had been significantly heavier at ages 6 months, 2 years, and 4 years (all P less than 0.025). Muscle mass, as estimated by the cross-sectional muscle area of the upper arm, had been significantly greater in the early maturers at the same ages (P less than 0.025 in seven of nine comparisons). Although the more sexually mature boys also had been taller and had had larger skinfolds at virtually all measurements from age 6 months to 4 years, the differences were less pronounced. In this adequately nourished male population, body size in the first years of life was significantly correlated with the timing of puberty.
