Abstract
BACKGROUND Childhood obesity represents a public health crisis in the United States. Thus, focusing on early childhood is crucial to modify the consequences associated with obesity. The Food and Fitness Initiative (FFI) is a community-based wellness program implemented in Northeast Iowa since 2009. FFI focuses on healthy eating and physical activity. Our aim is to describe the impact on body mass index (BMI) after implementing FFI in a Northeast Iowa Community Action Head Start (HS) population. METHODS Retrospective BMI data was collected from all children attending 14 HS sites from 2012 to 2018. Children with BMI measurements during July to December of the first year in HS were included in the study. Follow-up data the second year in HS was obtained. Overweight and obesity prevalence, as well as, BMI changes between year 1 and 2 in HS were analyzed. RESULTS Data from 1013 children were collected, 850 (84%) had qualifying BMI measurements during their first year in HS and 352 of those children (41%) had follow-up data in their second year. There was a decrease in BMI between years 1 and 2 in HS that approached statistical significance (t = 1.83, P = .07, d = .10). There were no statistically significant changes in the percent of overweight (Wald χ2 = .50, P = .48) or obese (Wald χ2 = 1.71, P = .19) children between the first and second year. CONCLUSION The FFI wellness program can be feasibly integrated into the HS curriculum and shows promising short-term results in improving BMI, but not to a statistically significant level when evaluated over 1 year.

Abstract
This project examines the Northeast Iowa Food and Fitness Initiative, a policy-, community-, and school-based effort to slow children's body mass index (BMI) growth over 6 years. Kindergarteners (K) to fifth graders (5) from 10 different school districts participated (N = 4101). Students with 0 to 1 years of initiative exposure showed greater growth in BMI compared with children who had 2 to 6 years of exposure, resulting in K-5 BMI savings of 1.5 points (6 lb) for median-height boys and girls. Results suggest that changes to policies, communities, and schools may provide effective obesity reduction in children.

Abstract
BACKGROUND Breastfeeding is associated with lower rates of obesity; in addition, it is also associated with later introduction of beverages and foods; however, this has not been well studied among Hispanics. The objective was to assess breastfeeding practices and timing of introduction of beverages and solid foods in a sample of Hispanic infants and their association with weight status. SUBJECT AND METHODS Cross-sectional study in 296 caregivers of infants and toddlers 0-24 months of age participants of a WIC clinic in Puerto Rico. Participants completed several questionnaires and anthropometrics were taken in infants and toddlers. Statistical analysis included correlations, comparison between groups and logistic regression. RESULTS A total of 189 participants older than 6 months completed the study. Most infants were breastfed immediately after birth (63.5 %), at the hospital (80.0 %), and at least once (92.3 %) but only 31 % were exclusively breastfed. Median duration of any breastfeeding was 5.0 months and exclusive breastfeeding was 0 months. Excessive weight was found in 22.8 %. Breastfeeding duration was positively associated with caregiver's educational level and age of introduction of water, formula, juice and cow's milk (p < 0.05). Exclusively breastfed infants were introduced water and formula at a later age compared to non-exclusively breastfed and never breastfed infants (p < 0.01). No significant associations were found between breastfeeding practices and duration or age of introduction of beverages and foods with weight status, even after adjusting for potential confounders. CONCLUSIONS Breastfeeding duration was in general low. Water, formula and juice were introduced later in breastfed infants compared to non-exclusively breastfed or never breastfed infants. Breastfeeding practices or timing of introduction of beverages and solid foods were not significantly associated with weight status. Strategies to support mothers on continuing breastfeeding beyond the hospital and for longer periods are needed among WIC participants to benefit of the protective effect on childhood obesity.

Abstract
OBJECTIVE This study assessed the prevalence and consistency of high values of weight, height, and BMI considered to be biologically implausible (BIV) using cut points proposed by WHO among 8.8 million low-income children (13.7 million observations). METHODS Cross-sectional and longitudinal analyses were performed among 2- to 4-year-olds who were examined from 2008 through 2011. RESULTS Overall, 2.7% of the body size measurements were classified as BIVs; 95% of these BIVs were very high. Among the subset of children (3.6 million) examined more than once, most of those who initially had a high weight or BMI BIV also had a high BIV at the second examination; odds ratios were >250. Based on several alternative classifications of BIVs, the current cut points likely underestimate the prevalence of obesity by about 1%. CONCLUSIONS Many of the extremely high values of body size currently flagged as BIVs are unlikely to be errors. Increasing the z-score cut points or using a percentage of the maximum values in the National Health and Nutrition Examination Survey, could improve the balance between removing probable errors and retaining those that are likely correct.

Abstract
BACKGROUND The WHO cutoffs to classify biologically implausible values (BIVs) for weight, height, and weight-for-height in children and adolescents are widely used in data cleaning. OBJECTIVES We assess 1) the prevalence of these BIVs, 2) whether they were consistent with information on waist circumference, arm circumference, and leg lengths, and 3) the effect of their exclusion on the estimated prevalence of obesity in 2- to 19-y-olds in the NHANES, which is a study in which extreme values were verified when recorded. DESIGN We conducted cross-sectional analyses in 26,480 children and adolescents in the NHANES from 1999-2000 through 2011-2012. RESULTS The overall prevalence for a BIV for any body-size measure was 0.9% (n = 277), and almost all BIVs were due to extremely high, rather than low, values. Of 186 subjects who had a high BIV for weight or body mass index (BMI), all but one subject had both arm and waist circumferences that were greater than the sex- and age-specific 95th percentiles; 75% of subjects had circumferences greater than the 99th percentile. Of 63 subjects with a high height BIV, 75% of them had a leg length that was greater than the 95th percentile. The exclusion of children and adolescents with a BIV reduced the overall prevalence of obesity by ∼0.5 percentage points and by 1.7% in non-Hispanic blacks. CONCLUSIONS Most of the extremely high values of weight, height, and BMI flagged as BIVs in the NHANES are very likely correct. The increase of z score cutoffs or the use of an alternative method to detect possible errors could improve the balance between removing incorrect values and retaining extremely high, but accurate, values in other data sets.

Abstract
As more epidemiologic data on childhood obesity become available, researchers are faced with decisions regarding how to determine biologically implausible values (BIVs) in height, weight, and body mass index. The purpose of the current study was 1) to track how often large, epidemiologic studies address BIVs, 2) to review BIV identification methods, and 3) to apply those methods to a large data set of youth to determine the effects on obesity and BIV prevalence estimates. Studies with large samples of anthropometric data (n > 1,000) were reviewed to track whether and how BIVs were defined. Identified methods were then applied to a longitudinal sample of 13,662 students (65% African American, 52% male) in 55 urban, low-income schools that enroll students from kindergarten through eighth grade (ages 5-13 years) in Philadelphia, Pennsylvania, during 2011-2012. Using measured weight and height at baseline and 1-year follow-up, we compared descriptive statistics, weight status prevalence, and BIV prevalence estimates. Eleven different BIV methods were identified. When these methods were applied to a large data set, severe obesity and BIV prevalence ranged from 7.2% to 8.6% and from 0.04% to 1.68%, respectively. Approximately 41% of large epidemiologic studies did not address BIV identification, and existing identification methods varied considerably. Increased standardization of the identification and treatment of BIVs may aid in the comparability of study results and accurate monitoring of obesity trends.

Abstract
The prevalence of obesity in the Hispanic preschool population remains elevated, particularly among children in low income families below the poverty level. Obesity leads to the early onset of metabolic syndrome and Type 2 diabetes. The Head Start population of Texas is largely comprised of this high risk group. Their physical activity level is suboptimal in part due to lack of available outside play areas and time spent watching television and playing sedentary video games. Dietary intake is frequently high in sugar sweetened beverages and low in vegetables. The group is frequently bilingual with limited vocabulary and has not learned to read. Preserving their Mexican American culture is a concern. This article describes the development and assessment of a group of bilingual interactive video interventions to improve age appropriate physical activity while providing basic nutrition education focusing on increasing vegetable and water intake and decreasing sugar sweetened beverages. Suggestions for development and assessment of content were provided by focus groups of Head Start teachers, managers and dietitians in the Texas counties of Bastrop, Hidalgo and McLennon. A demonstration of the videos was conducted in Bastrop County. Teachers, students and managers felt that the videos provided excellent information, improved exercise participation and engaged the children.

Abstract
INTRODUCTION New York City Article 47 regulations, implemented in 2007, require licensed child care centers to improve the nutrition, physical activity, and television-viewing behaviors of enrolled children. To supplement an evaluation of the Article 47 regulations, we conducted an exploratory ecologic study to examine changes in childhood obesity prevalence among low-income preschool children enrolled in the Nutrition Program for Women, Infants, and Children (WIC) in New York City neighborhoods with or without a district public health office. We conducted the study 3 years before (from 2004 through 2006) and after (from 2008 through 2010) the implementation of the regulations in 2007. METHODS We used an ecologic, time-trend analysis to compare 3-year cumulative obesity prevalence among WIC-enrolled preschool children during 2004 to 2006 and 2008 to 2010. Outcome data were obtained from the New York State component of the Centers for Disease Control and Prevention's Pediatric Nutrition Surveillance System. RESULTS Early childhood obesity prevalence declined in all study neighborhoods from 2004-2006 to 2008-2010. The greatest decline occurred in Manhattan high-risk neighborhoods where obesity prevalence decreased from 18.6% in 2004-2006 to 15.3% in 2008-2010. The results showed a narrowing of the gap in obesity prevalence between high-risk and low-risk neighborhoods in Manhattan and the Bronx, but not in Brooklyn. CONCLUSION The reductions in early childhood obesity prevalence in some high-risk and low-risk neighborhoods in New York City suggest that progress was made in reducing health disparities during the years just before and after implementation of the 2007 regulations. Future research should consider the built environment and markers of differential exposure to known interventions and policies related to childhood obesity prevention.

Abstract
BACKGROUND National WIC (the Special Supplemental Nutrition Program for Women, Infants, and Children) data indicate a decrease in obesity prevalence among most low-income preschool-aged children. Though racial/ethnic disparities exist, studies examining obesity trends among various racial/ethnic groups are lacking. The aims of this study were to identify racial/ethnic disparities in obesity among low-income preschool children in Oklahoma and describe trends in obesity prevalence among four major racial/ethnic groups. METHODS Subjects included 218,486 children 2-4 years of age who participated in WIC in Oklahoma from 2005 to 2010. Logistic regression was performed to identify disparities and trends in obesity among American Indian, Hispanic, White, and African American children. RESULTS Racial/ethnic disparities in obesity were evident, with prevalence highest in Hispanics and lowest in African Americans. Obesity increased among girls for all racial/ethnic groups from 2005 to 2010 (odds ratio [OR], 1.02; 95% confidence interval [CI], 1.01, 1.03). Among boys, obesity increased in African Americans (OR, 1.04; 95% CI, 1.01, 1.07), but remained stable in other racial/ethnic groups. CONCLUSIONS In Oklahoma, in contrast to recent national studies, obesity is increasing among certain groups of low-income preschool children. These findings suggest geographic diversity in obesity and that state-specific obesity surveillance is important to help target interventions to those at highest risk.

Abstract
BACKGROUND Visceral adiposity index (VAI) is a novel gender-specific index based on waist circumference (WC), BMI, and lipid parameters. Although VAI does not actually estimate visceral adiposity, it accurately reflects visceral fat function and insulin resistance. This index has not been studied in children thus far. This study aims to fill this gap. METHODS In a cohort of Saudi children and adolescents, anthropometric measurements and metabolic/hormonal profile were obtained. RESULTS A total of 543 subjects, 292 of whom were boys, were included (mean age: 11.9 ± 3.3 y; BMI: 19.8 ± 5.6 kg/m(2)). In all subjects, VAI was inferior to BMI and WC regarding its correlations with adiponectin, leptin, insulin resistance (homeostasis model of assessment-insulin resistance (HOMA-IR)), C-reactive protein (CRP) level, and systolic blood pressure, but it exhibited a stronger association with glucose in boys (r = 0.23; P < 0.01). In stepwise multivariate analyses, only BMI was consistent as an independent predictor of adiponectin, leptin, HOMA-IR, and CRP. VAI was the only index independently associated with glucose. CONCLUSION Although VAI is related to glucose in children, it seems to be inferior to BMI in terms of association with insulin resistance, adipokines, and subclinical inflammation. Until specific studies can be performed in children, VAI should be extrapolated with caution in this age range.

Abstract
OBJECTIVES We tested the hypothesis that early enrollment in the Special Supplemental Nutrition Program for Women, Infants and Children (WIC) is associated with a reduced risk of rapid infant weight gain (RIWG). METHODS We used a longitudinal cohort of mother-infant pairs (n = 157,590) enrolled in WIC in New York State from 2008 to 2009 and estimated the odds of RIWG, defined as a 12-month change in weight-for-age z score of more than .67, comparing infants of mothers enrolled during the first, second, or third trimester of pregnancy with those who delayed enrollment until the postpartum period. RESULTS After adjusting for potential confounders, the odds of RIWG (odds ratio [OR] = 0.76; 95% confidence interval [CI] = 0.74, 0.79) were significantly lower for infants of women enrolling during the first trimester versus postpartum. Birth weight-for-gestational-age z score (OR = 0.33; 95% CI = 0.32, 0.33) attenuated the estimate of prenatal versus postpartum enrollment (OR = 0.92; 95% CI = 0.88, 0.95; first-trimester enrollees). CONCLUSIONS The results demonstrate that prenatal WIC participation is associated with reduced risk of RIWG between birth and age 1 year. Improved birth weight for gestational age may be the mechanism through which early prenatal WIC enrollment protects against RIWG.

Abstract
BACKGROUND The prevalence of obesity among U.S. preschoolers has doubled in recent decades. Childhood obesity increases the risk for adult obesity and is associated with negative health consequences. Trends in the state-specific prevalence of obesity among low-income U.S. preschool children have not been examined since 2008. State-specific obesity prevalence surveillance helps determine the need for and impact of state and local obesity prevention strategies. METHODS Measured weight and height data from approximately 11.6 million low-income children aged 2-4 years from 40 states, the District of Columbia, and two U.S. territories who participated in the Pediatric Nutrition Surveillance System during 2008-2011 were used to estimate state obesity prevalence. Obesity was defined as having an age- and sex-specific body mass index ≥95th percentile, according to the 2000 CDC growth charts. Logistic regression models adjusted for age, sex, and race/ethnicity were used to examine trends in the state-specific obesity prevalence. RESULTS During 2008-2011, statistically significant downward trends in obesity prevalence were observed in 18 states and the U.S. Virgin Islands. Florida, Georgia, Missouri, New Jersey, South Dakota, and the U.S. Virgin Islands had the largest absolute decreases in obesity prevalence, each with a decrease of ≥1 percentage point. Twenty states and Puerto Rico experienced no significant change, and obesity prevalence increased significantly in three states. CONCLUSIONS AND IMPLICATIONS FOR PUBLIC HEALTH PRACTICE: Small but significant declines in obesity among low-income preschoolers were observed in 19 of 43 states/territories examined. Continued prevention efforts are needed to sustain and expand the implementation and evaluation of population-level interventions to prevent childhood obesity.

Abstract
OBJECTIVE This study assessed the impact of revisions to the USDA Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) food packages on nutritional behavior and obesity in children 0- to 4-years-old participating in the New York State (NYS) WIC program. In January 2009, NYS was the first to implement these revisions, which added fruits, vegetables, and whole grains and replaced whole milk with low(1%)-/nonfat milk for children 2- to 4-year-old. DESIGN AND METHODS In this cross-sectional study, >3.5 million administrative records in the NYS WIC Statewide Information System (WICSIS) were analyzed at 6-month intervals from July to December 2008 (pre-implementation) through July to December 2011. Behavioral data in WICSIS were obtained from parent interview by WIC staff at mandatory certification and recertification visits. RESULTS Comparing July to December in 2008 and 2011, increases were observed in breastfeeding initiation (72.2-77.5%); delaying introduction of solid foods until after 4 months of age (90.1-93.8%); daily fruit (87.0-91.6%), vegetable (78.1-80.8%), and whole grain consumption (59.0-64.4%) by children aged 1-4 years; and switches from whole milk to low-/nonfat milk by children aged 2-4 years (66.4-69.4%). In 1-year-old children, the proportion ≥95th percentile weight-for-recumbent length decreased from 15.1 to 14.2%; the proportion of children 2- to 4-year-old with body mass index (BMI) ≥95th percentile decreased from 14.6 to 14.2%. CONCLUSIONS These findings demonstrate that positive changes in dietary intake and reductions in obesity followed implementation of the USDA-mandated cost-neutral revisions to the WIC food package for the hundreds of thousands of young children participating in the NYS WIC program.

Abstract
AIM To assess time trends in overweight and obesity prevalence among 5-6-year-old children of Bordeaux city (France) over seven school years from 2004-2005 to 2010-2011. METHODS For each year, all 5-6-year-old children from 63 of the 69 schools of Bordeaux were included: 2005, 2100, 2010, 1952, 2040, 2017 and 2111 subjects, respectively. Weight and height were collected by school doctors, and weight status was defined according to the age- and sex-specific body mass index cut-off points of the International Obesity Task Force (IOTF) for obesity and to the French age- and gender-specific child cut-off (close to the IOTF cut-off) for overweight including obesity. RESULTS From 2004-2005 to 2010-2011, an overall decrease was observed in overweight including obesity (from 8.9% to 5.2%, p < 0.001) and obesity prevalences (from 2.8% to 1.4%, p = 0.046). Similar results were observed in non-low socio-economic status (SES) areas (p < 0.001), whereas the prevalence did not vary significantly in low-SES areas (p > 0.05). CONCLUSION Overweight prevalence has decreased between 2004 and 2011 in 5-6-year-old children from Bordeaux. However, the gap between low and non-low-SES areas has persisted during these years.

Abstract
OBJECTIVE This pilot study tested the feasibility of Family-Based Hip-Hop to Health, a school-based obesity prevention intervention for 3-5-year-old Latino children and their parents, and estimated its effectiveness in producing smaller average changes in BMI at 1-year follow-up. DESIGN AND METHODS Four Head Start preschools administered through the Chicago Public Schools were randomly assigned to receive a Family-Based Intervention (FBI) or a General Health Intervention (GHI). RESULTS Parents signed consent forms for 147 of the 157 children enrolled. Both the school-based and family-based components of the intervention were feasible, but attendance for the parent intervention sessions was low. Contrary to expectations, a downtrend in BMI Z-score was observed in both the intervention and control groups. CONCLUSIONS While the data reflect a downward trend in obesity among these young Hispanic children, obesity rates remained higher at 1-year follow-up (15%) than those reported by the National Health and Nutrition Examination Survey (2009-2010) for 2-5-year-old children (12.1%). Developing evidence-based strategies for obesity prevention among Hispanic families remains a challenge.

Abstract
Recent studies have reported evidence of a leveling and decline in childhood obesity prevalence in New York and California. However, some areas of the United States continue to experience increases in the prevalence of childhood obesity. To assess differences and changes over time in early childhood obesity in the two most populous cities in the United States, obesity prevalence among low-income, preschool-aged children enrolled in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) in New York City (NYC) was compared with obesity prevalence among WIC-enrolled children in Los Angeles County (LAC) during 2003-2011. In NYC, from 2003 to 2011, obesity prevalence decreased among blacks, whites, and Hispanics, but increased among Asians. In LAC, obesity prevalence decreased among Asians and increased and then decreased among blacks and Hispanics from 2003 to 2011. Hispanic WIC-enrolled children had the greatest prevalence of obesity for all years in both areas. In 2011, the obesity prevalence among Hispanics in NYC was 19.1%, compared with 21.7% in LAC. Comparisons of obesity prevalence data among cities and states might suggest interventions and policies to help reverse childhood obesity increases in some populations.

Abstract
CONTEXT The system of local health departments (LHDs) in the United States has the potential to advance a locally oriented public health response in obesity control and reduce geographic disparities. However, the extent to which obesity prevention programs correspond to local obesity levels is unknown. OBJECTIVE This study examines the extent to which LHDs across the United States have responded to local levels of obesity by examining the association between jurisdiction-level obesity prevalence and the existence of obesity prevention programs. DESIGN Data on LHD organizational characteristics from the Profile Study of Local Health Departments and county-level estimates of obesity from the Behavioral Risk Factor Surveillance System were analyzed (n = 2300). Since local public health systems are nested within state infrastructure, multilevel models were used to examine the relationship between county-level obesity prevalence and LHD obesity prevention programming and to assess the impact of state-level clustering. SETTING Two thousand three hundred local health department jurisdictions defined with respect to county boundaries. PARTICIPANTS Practitioners in local health departments who responded to the 2005 Profile Study of Local Health Departments. MAIN OUTCOME MEASURES Likelihood of having obesity prevention activities and association with area-level obesity prevalence. RESULTS The existence of obesity prevention activities was not associated with the prevalence of obesity in the jurisdiction. A substantial portion of the variance in LHD activities was explained by state-level clustering. CONCLUSIONS This article identified a gap in the local public health response to the obesity epidemic and underscores the importance of multilevel modeling in examining predictors of LHD performance.

Abstract
This report summarizes a conference: “Early Origins of Child Obesity: Bridging Disciplines and Phases of Development”, held in Chicago on September 30–October 1, 2010. The conference was funded in part by the National Institutes of Health and the Williams Heart Foundation, to achieve the conference objective: forging a next-step research agenda related to the early origins of childhood obesity. This research agenda was to include working with an array of factors (from genetic determinants to societal ones) along a continuum from prenatal life to age 7, with an emphasis on how the developing child deals with the challenges presented by his/her environment (prenatal, parental, nutritional, etc.). The conference offered a unique opportunity to facilitate communication and planning of future work among a variety of researchers whose work separately addresses different periods in early life. Over the span of two days, speakers addressed existing, critical research topics within each of the most-studied age ranges. On the final day, workshops fostered the discussion needed to identify the highest priority research topics related to linking varied early factor domains. These are presented for use in planning future research and research funding.

Abstract
CONTEXT The prevalence of childhood obesity increased in the 1980s and 1990s but there were no significant changes in prevalence between 1999-2000 and 2007-2008 in the United States. OBJECTIVES To present the most recent estimates of obesity prevalence in US children and adolescents for 2009-2010 and to investigate trends in obesity prevalence and body mass index (BMI) among children and adolescents between 1999-2000 and 2009-2010. DESIGN, SETTING, AND PARTICIPANTS Cross-sectional analyses of a representative sample (N = 4111) of the US child and adolescent population (birth through 19 years of age) with measured heights and weights from the National Health and Nutrition Examination Survey 2009-2010. MAIN OUTCOME MEASURES Prevalence of high weight-for-recumbent length (≥95th percentile on the growth charts) among infants and toddlers from birth to 2 years of age and obesity (BMI ≥95th percentile of the BMI-for-age growth charts) among children and adolescents aged 2 through 19 years. Analyses of trends in obesity by sex and race/ethnicity, and analyses of trends in BMI within sex-specific age groups for 6 survey periods (1999-2000, 2001-2002, 2003-2004, 2005-2006, 2007-2008, and 2009-2010) over 12 years. RESULTS In 2009-2010, 9.7% (95% CI, 7.6%-12.3%) of infants and toddlers had a high weight-for-recumbent length and 16.9% (95% CI, 15.4%-18.4%) of children and adolescents from 2 through 19 years of age were obese. There was no difference in obesity prevalence among males (P = .62) or females (P = .65) between 2007-2008 and 2009-2010. However, trend analyses over a 12-year period indicated a significant increase in obesity prevalence between 1999-2000 and 2009-2010 in males aged 2 through 19 years (odds ratio, 1.05; 95% CI, 1.01-1.10) but not in females (odds ratio, 1.02; 95% CI, 0.98-1.07) per 2-year survey cycle. There was a significant increase in BMI among adolescent males aged 12 through 19 years (P = .04) but not among any other age group or among females. CONCLUSION In 2009-2010, the prevalence of obesity in children and adolescents was 16.9%; this was not changed compared with 2007-2008.

Abstract
BACKGROUND Childhood obesity has reached epidemic levels. Children obesity predisposes them to risk of cardiac disease in adulthood. Environmental factors, lifestyle preferences, and cultural environment play pivotal roles in the rising prevalence of obesity worldwide. Furthermore, family life style has a great influence on children obesity. This study aimed to determine the effect of family-oriented weight reduction program on the children's anthropometric measurements. METHODS This was a non-pharmacological clinical trial study which was performed on 4-18 years old children attending outpatient clinics of Isfahan Endocrine and Metabolism. Anthropometric measurements were recorded for all the participants. Children took part in one educational session in which they were taught about ways and benefits of having a regular physical activity each day and also benefits of having healthy nutrition. All the participants took part in every 4 months one-hour educational sessions and their anthropometrics were measured. RESULTS Fifty eight single-mother families participated in this study. Fourteen single-father families started the intervention but did not follow it to the end. Children's body mass index (BMI) z-score decreased significantly after the study. Children waist circumference (WC) and hip circumference (HC) significantly increased. Mothers WC and waist to hip ratio (WHR) increased significantly. Regression test showed that mother BMI was an independent factor (B = 0.307; P < 0.021). The effect of the pattern of children's BMI changed across a one-year period. CONCLUSION Our study showed significant effect of repetitive family life style education on children's BMI z-score changes. Family, as the first place for children behavior formation, must be regarded as one of the best place to tackle childhood obesity.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is becoming as an important health problem in the pediatric age group. In addition to the well-documented role of obesity on the fatty changes in liver, there is a growing body of evidence about the role of environmental factors, such as smoking and air pollution, in NAFLD. Given that excess body fat and exposure to air pollutants is accompanied by systemic low-grade inflammation, oxidative stress, as well as alterations in insulin/insulin-like growth factor and insulin resistance, all of which are etiological factors related to NAFLD, an escalating trend in the incidence of pediatric NAFLD can be expected in the near future. This review focuses on the current knowledge regarding the epidemiology, diagnosis and pathogenesis of pediatric NAFLD. The review also highlights the importance of studying the underlying mechanisms of pediatric NAFLD and the need for broadening efforts in prevention and control of the main risk factors. The two main universal risk factors for N LD, obesity and air pollution, have broad adverse health effects, and reducing their prevalence will help abate the serious health problems associated with pediatric NAFLD.

Abstract
The objective of this study was to analyse interventions for the prevention of overweight and obesity in children under 5 years of age. We carried out a systematic review focusing exclusively on randomized controlled trials (RCTs). Data sources include Medline, Cochrane Library, EMBASE, CINHAL, PsychInfo and Web of Science. Data were extracted from seventeen articles describing seven RCTs identified through electronic search, screening of references in systematic reviews, own files and contact with authors. RCTs were assessed with the Jadad scale. Four trials were carried out in preschool settings, one with an exclusive educational component, two with an exclusive physical activity component and one with both. Two trials were family-based, with education and counselling for parents and children. The remaining trial was carried out in maternity hospitals, with a training intervention on breastfeeding. None of the interventions had an effect in preventing overweight and obesity. The failure to show an effect may be due to the choice of outcomes, the quality of the RCTs, the suboptimal implementation of the interventions, the lack of focus on social and environmental determinants. More rigorous research is needed on interventions and on social and environmental factors that could impact on lifestyle.

Abstract
Childhood obesity is a major worldwide health problem. Intervention programs to ameliorate the rate of obesity have been designed and implemented; yet the epidemic has no end near in sight. AMP-activated protein kinase (AMPK) has become one of the most important key elements in energy control, appetite regulation, myogenesis, adipocyte differentiation, and cellular stress management. Obesity is a multifactorial disease, which has a very strong genetic component, especially epigenetic factors. The intrauterine milieu has a determinant impact on adult life, since the measures taken for survival are kept throughout life thanks to epigenetic modification. Nutrigenomics studies the influence of certain food molecules on the metabolome profile, raising the question of an individualized obesity therapy according to metabolic (and probably) genetic features. Metformin, an insulin sensitizing agent, its known to lower insulin resistance and enhance metabolic profile, with an additional weight reduction capacity, via activation of AMPK. Exercise is coadjutant for lifestyle modifications, which also activates AMPK in several ways contributing to glucose and fat oxidation. The following review examines AMPK's role in obesity, applying its use as a tool for childhood and adolescent obesity.
