Abstract
BACKGROUND Maternal obesity and rapid infant weight gain have been associated with increased risk of obesity in childhood. Breastfeeding is suggested to be protective against childhood obesity, but no previous study has addressed the potential benefit of breastfeeding as a preventive method of childhood obesity amongst obese women. The primary aim of this study was to assess the relationship between mode of feeding and body composition, growth and eating behaviours in 6-month-old infants of obese women who participated in UPBEAT; a multi-centre randomised controlled trial comparing a lifestyle intervention of diet and physical activity to standard care during pregnancy. METHODS Three hundred and fifty-three mother and infant pairs attended a 6-months postpartum follow-up visit, during which they completed the Baby-Eating Behaviour Questionnaire, a parent-reported psychometric measure of appetite traits. Measures of infant body composition were also undertaken. As there was no effect of the antenatal intervention on infant feeding and appetite the study was treated as a cohort. Using regression analyses, we examined relationships between: 1) mode of feeding and body composition and growth; 2) mode of feeding and eating behaviour and 3) eating behaviour and body composition. RESULTS Formula fed infants of obese women in comparison to those exclusively breastfed, demonstrated higher weight z-scores (mean difference 0.26; 95% confidence interval 0.01 to 0.52), higher rate of weight gain (0.04; 0.00 to 0.07) and greater catch-up growth (2.48; 1.31 to 4.71). There was also a lower enjoyment of food (p = 0.002) amongst formula fed infants, following adjustment for confounders. Independent of the mode of feeding, a measure of infant appetite was associated with sum of skinfold thicknesses (β 0.66; 95% CI 0.12 to 1.21), calculated body fat percentage (0.83; 0.15 to 1.52), weight z-scores (0.21; 0.06 to 0.36) and catch-up growth (odds ratio 1.98; 1.21 to 3.21). CONCLUSIONS In obese women, exclusive breastfeeding was protective against increasing weight z-scores and trajectories of weight gain in their 6-month old infants. Measures of general appetite in early infancy were associated with measures of adiposity, weight and catch up growth independent of cord blood leptin concentrations and mode of early feeding.

Abstract
PURPOSE To investigate the effects of a low- versus high-intensity aerobic training on biomarkers of inflammation and endothelial dysfunction in adolescents with obesity. METHODS Sixty-two adolescents with obesity [age = 15 (14) y, body mass index = 34.87 (4.22) kg·m-2] were randomized to receive either a high-intensity training (HIT, n = 31) or a low-intensity training (LIT, n = 31) for 24 weeks. All participants also received nutritional, psychological, and clinical counseling. Leptin, total and subtype leukocyte counts, tumor necrosis factor-alpha, interleukin-6, myeloperoxidase, soluble intercellular adhesion molecule-1, and soluble vascular cell adhesion molecule-1 were obtained at baseline and after 24 weeks. RESULTS HIT reduced neutrophils [from 4.4 (1.9) to 3.6 (1.3) µL-1 × 103; P = .01] and monocytes [from 7.2 (2.5) to 5.2 (1.8) µL-1 × 102; P < .01], but LIT increased neutrophils [from 4.5 (1.7) to 5.2 (3.3) µL-1 × 103; P = .01]. Although tumor necrosis factor-alpha increased in LIT [from 13.3 (7.5) to 17.7 (10.8) pg·mL-1; P = .01], it decreased in HIT [from 12.4 (7.5) to 11.3 (6.2) pg·mL-1; P = .01]. No changes in leukocyte counts, soluble intercellular adhesion molecule-1, soluble vascular cell adhesion molecule-1, and homeostasis assessment model for insulin resistance were observed. CONCLUSIONS Both HIT and LIT improved the inflammatory profile. The study, however, indicated that the number of biomarkers and the magnitude of changes were higher in the HIT compared with LIT.

PloS one. 2018;(12):e0209787
Abstract
INTRODUCTION The obesity rate in preschool children in the United States (US) is 13.9%, while even higher rates are associated with racial and ethnic minorities and children from low-income families. These prevalence patterns underscore the need to identify effective childhood obesity prevention programs. METHOD A scoping review was conducted following Arksey and O'Malley's framework to provide an overview of the types, effectiveness and cost-effectiveness of obesity prevention interventions and policies in children up to 6 years old. Inclusion criteria were studies at least 6-months duration; included a weight-based outcome, conducted in the US, English publications from January 2001 to February 2018. Exclusions: studies in overweight/obese children and obesity treatments, no comparator group. Evidence was characterized across the early life course and multiple-levels of influence. RESULTS From the 2,180 records identified, 34 met the inclusion criteria. Less than half of the interventions initiated during pregnancy, infancy or preschool reported a significant improvement in a weight-based outcome. All interventions included strategies to influence individual- or interpersonal-level health behaviors, yet few removed obstacles in the healthcare system, physical/built environment, or sociocultural environment. The majority (78%) of the interventions occurred during preschool years, with 63% conducted in early childcare education settings serving low-income families. The health impact of the state-wide and national policies on children under age 6 years remains unclear. There was considerable uncertainty around estimates of the health and economic impacts of obesity prevention interventions and policies. CONCLUSION There is a need to intensify early childhood obesity preventive efforts during critical periods of health development in the US. Future studies should estimate the feasibility, program effectiveness, and cost of implementing multilevel obesity prevention interventions and policies. Addressing these research gaps will provide stakeholders with the scientific evidence necessary to facilitate funding and policy decisions to decrease the prevalence of early childhood obesity.

Abstract
OBJECTIVE To assess the feasibility of engaging stressed, low-income parents with obesity in a novel mindfulness-based parent stress intervention aimed at decreasing the risk of early childhood obesity. STUDY DESIGN An 8-week mindfulness-based parent stress group intervention (parenting mindfully for health) plus nutrition and physical activity counseling (PMH+N) was developed for parents with obesity aimed at preventing obesity in their at-risk 2- to 5-year-old children. PMH+N was compared with a control group intervention (C+N), and improvement in parenting was assessed before and after the intervention using the laboratory-based toy wait task (TWT). In addition, nutrition, physical activity, and stress were assessed using a multimethod approach. RESULTS After establishing feasibility in 20 parent-child dyads (phase 1), 42 dyads were randomized to PMH+N vs C+N (phase 2). Compared with the C+N group, the PMH+N group demonstrated significantly better group attendance (P < .015), greater improvement in parental involvement (P < .05), and decreased parental emotional eating rating (P < .011). Furthermore, C+N, but not PMH+N, was associated with significant increases in child body mass index percentile during treatment (P < .03) when accounting for the TWT before and after changes in parenting scores. CONCLUSIONS These findings suggest that a mindfulness-based parent stress intervention to decrease childhood obesity risk is feasible, requires further testing of therapeutic mechanisms in larger samples, and may be a potential way to attenuate the risk of childhood obesity.

BMC public health. 2018;(1):669
Abstract
BACKGROUND Childhood obesity is a public health issue negatively affecting children's physical and psychosocial health. Mothers are children's primary caregivers, thus key players in childhood obesity prevention. Studies have indicated that mothers underestimate their children's weight. If mothers are unaware of their children's weight problem, they are less likely to participate in activities preventing and treating excess weight. The "Healthy Change" intervention is designed to change maternal perception of child's weight (MPCW) through peer-led group health education in childcare settings. METHODS/DESIGN The "Healthy Change" is a multicenter two-arm randomized trial in four centers. Three centers are in Mexican States (Nuevo Leon, Tamaulipas, and Zacatecas). The fourth center is in San Antonio, Texas, USA. A total of 360 mother-child pairs (90 pairs per center) are to be randomly and evenly allocated to either the intervention or the control group. Intervention group will receive four-session group obesity prevention education. Control group will receive a four-session personal and food hygiene education. The education is delivered by trained peer-mother promotoras. Data will be collected using questionnaires and focus groups. The primary outcome is a change in proportion of mothers with accurate MPCW. Secondary outcomes include change in maternal feeding styles and practices, maternal self-efficacy and actions for managing child excessive weight gain. McNemar's Test will be used to test the primary outcome. The GLM Univariate procedure will be used to determine intervention effects on secondary outcomes. The models will include the secondary outcome measures as the dependent variables, treatment condition (intervention/control) as the fixed factor, and confounding factors (e.g., mother's education, children's gender and age) as covariates. Sub-analyses will be performed to compare intervention effects on primary and secondary outcomes between the samples from Mexico and Texas, USA. Qualitative data will be analyzed through analysis of inductive content. A combined coding model will be developed and used to code transcripts using the NVivo software. DISCUSSION Healthy Change intervention could help change MPCW, an initial step for obesity prevention among preschoolers. This study presents a first of its kind intervention available in Spanish and English targeting Mexican and Mexican-American mothers in Mexico and USA. TRIAL REGISTRATION ISRCTN12281648.

Canadian journal of dietetic practice and research : a publication of Dietitians of Canada = Revue canadienne de la pratique et de la recherche en dietetique : une publication des Dietetistes du Canada. 2018;(2):86-90
Abstract
PURPOSE The Guelph Family Health Study (GFHS) pilot was designed to examine the feasibility and effectiveness of a home-based obesity prevention intervention on health behaviours and obesity risk. The objective of this analysis was to determine the effect of the 6-month intervention on preschool-aged children's dietary intakes. METHODS Families with children aged 1.5-5 years old were randomized to receive one of the following: 4 home visits with a health educator as well as tailored emails and mailed incentives (4HV; n = 19 children); 2 home visits with a health educator as well as tailored emails and mailed incentives (2HV; n = 14 children); or general health advice through emails (control; n = 12 children). Three-day food records were completed by parents for their children before and after the 6-month intervention and analyzed for 3-day average intakes of energy, nutrients, and MyPlate food groups. RESULTS After the 6-month intervention, the 4HV group had significantly higher fibre intake and the 4HV and 2HV groups had significantly higher fruit intake, both compared with the control group. CONCLUSIONS This study provides support for a home-based intervention approach to improve the diet quality of preschool-aged children.

Abstract
BACKGROUND Little is known regarding the nutritional burden in Chinese ethnic minority children. This study aimed to investigate the epidemiological characteristics of excess body weight and underweight for 26 ethnic groups. METHODS Data on 80,821 participants aged 7-18 years across 26 minorities, with completed records from a large national cross-sectional survey, were obtained from Chinese National Survey on Students' Constitution and Health (CNSSCH) in 2014. Excess body weight, underweight and their components were classified according to Chinese national BMI references. RESULTS The overall prevalence of excess body weight and underweight among ethnic groups were 12.0% and 14.5%, in which 4.4% and 4.1% of the participants were classified as obese and severe wasting, respectively. Compared with girls, boys showed a higher prevalence of underweight, severe wasting and obesity, but a lower prevalence of excess body weight (P < 0.05). Among 26 ethnic groups, Koreans had the highest prevalence of excess body weight (30.4%), while Bouyeis showed the highest prevalence of underweight (25.7%). The ethnic minority groups with high prevalence of excess body weight and underweight were more likely to show high burden of obesity and severe wasting, respectively. However, it is not the case for some groups, such as Miaos and Shuis. CONCLUSIONS A worrying dual burden of excess body weight and underweight was recognized in Chinese ethnic minority children. Since various characteristics were found among different minorities, the ethnic-specific effort is warranted to improve their nutritional status.

Abstract
Schools are a recommended place for childhood obesity prevention. Local Wellness Policies (LWPs) establish guidelines for schools to provide opportunities for students to access nutritious foods and be physically active. Little is known about the impact of LWPs, when implemented, on students' behavior and body mass index (BMI). The Wellness Champions for Change trial assesses the student-level impact of providing theory-based training and technical assistance to help schools implement LWPs. This 3-arm, cluster randomized controlled trial will take place in 30 low- or middle-income schools (15 elementary and 15 middle) in five Maryland school districts. Ten schools will receive both Wellness Champions for Change (WCC), which involves training teacher-led wellness teams, and Wellness Champions for Change-Student (WCC-S), which engages students as wellness team members. Ten schools will receive WCC only, and ten control schools will receive a delayed intervention. The RE-AIM framework will guide evaluation. Student Effectiveness measures will include BMI z-scores, self-reported diet patterns, and objectively-measured physical activity. The sample size (1080 students across 30 schools, followed for 2.5 years) will enable power (>0.8) to detect BMI z-score differences. A three-level linear mixed model that accounts for clustering will be used to assess Effectiveness. A mixed methods approach will assess school- and district-level Reach, Adoption, and Implementation. If effective, this approach will represent a sustainable, multi-level, school-based strategy to prevent childhood obesity. The evaluation framework will allow for the description of factors necessary to broadly disseminate this approach for obesity prevention on a large scale.

Abstract
BACKGROUND Picky eating is common in children. Few studies have examined predictors of picky eating, and the association of picky eating with weight status and dietary quality is inconsistent in the literature. We aimed to identify predictors of picky eating and to test the association of picky eating with child body mass index z-score (BMIz), dietary quality, and micronutrient intake. METHODS This was a cross-sectional analysis of baseline data from a randomized controlled trial to prevent obesity among 506 preschoolers attending Head Start. Parents completed questionnaires to assess picky eating and child temperament. Three 24-hour dietary recalls were collected to assess dietary intake. Multivariate regression models assessed child, parent, and family predictors of picky eating; additional models tested adjusted associations of picky eating with child BMIz, dietary quality (measured using the Healthy Eating Index-2010), and micronutrient intake. RESULTS Picky eating was predicted by male sex, older child age, and more difficult temperament but not race/ethnicity, maternal body mass index, maternal depressive symptoms, household food insecurity, or single parent home. Picky eating was not associated with child BMIz or micronutrient deficiencies; it was inversely associated with total Healthy Eating Index-2010 score and servings of whole fruit, total vegetables, greens and beans, and total protein foods. CONCLUSIONS Pediatric providers should support parents in expanding the number of healthy foods the child eats to improve dietary quality, but reassure parents that picky eating is not associated with children's weight status or micronutrient deficiencies.
