Physical Activity at Different Life Stages and Its Consequence on the Initial Immunization and Inflammatory Response Against COVID-19. J Phys Act Health 2024; 21:717-725. [PMID: 38663845 DOI: 10.1123/jpah.2023-0370] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2023] [Revised: 02/16/2024] [Accepted: 03/08/2024] [Indexed: 06/25/2024]
Abstract
BACKGROUND To evaluate the influence of previous physical activity (PA) during childhood, adolescence, and current PA practice on the production of antibodies and inflammatory response between the first and second doses of the COVID-19 vaccine. METHODS Fifty-nine men and 56 women were evaluated before the first vaccine, and 12 weeks later, blood samples were taken to quantify production of anti-severe acute respiratory syndrome coronavirus-2 immunoglobulin G antibodies and cytokines. Previous PA during childhood and adolescence was self-referred, and current PA was assessed using the International Physical Activity Questionnaire. RESULTS A positive and significant association was observed only between PA practice during adolescence and an increase in antibody production in adulthood (β = 2012.077, 95% confidence interval, 257.7953-3766.358, P = .025). Individuals who practiced PA during adolescence showed higher production of antibodies between the first and second vaccine dose compared to nonpractitioners (P = .025) and those that accumulated ≥150 minutes per week of current moderate-vigorous PA (MVPA), and presented higher antibody production in relation to who did <150 minutes per week of MVPA (P = .046). Individuals that were practitioners during childhood produced higher G-CSF (P = .047), and those that accumulated ≥150 minutes per week of current MVPA demonstrated lower IP-10 levels (P = .033). However, PA practitioners during adolescence presented higher G-CSF (P = .025), IL-17 (P = .038), IL-1RA (P = .005), IL-1β (P = .020), and IL-2 (P = .026) levels. CONCLUSION Our results suggest that adults that accumulated at least 150 minutes of MVPA per week or practiced PA during adolescence developed an improved immune and inflammatory response against COVID-19 vaccination.

Abstract
Childhood obesity is a growing concern worldwide, with significant implications for public health. Of particular interest is its association with the early onset of type 2 diabetes mellitus in children. Exploring this relationship and identifying contributing factors may help strengthen understanding of this complex relationship. Factors such as family history, gender, and sedentary lifestyle, and poor dietary habits, insulin resistance in adipose tissue have been identified as significant contributors to early-onset type 2 diabetes. The rising prevalence of childhood obesity and its association with diabetes necessitates early interventions to mitigate this concerning trend and ensure a lasting impact on public health. This scoping review aims to investigate the relationship between childhood obesity and early-onset type 2 diabetes mellitus while also exploring other contributing factors. We employed a standardized framework for reviews to analyze relevant literature published in English between 2000 and 2021. Only primary research, systematic reviews, and meta-analyses addressing the association between childhood obesity and early-onset type 2 diabetes mellitus were included. The review adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) format. Out of the 3614 articles assessed, 17 were ultimately incorporated into this scoping review as they met the inclusion criteria. The majority of the literature primarily represented North American studies, with no inclusion of studies from South America. The findings from these studies have highlighted several factors contributing to type 2 diabetes mellitus development. Most of the studies associated obesity development with hypertension and unfavorable lipid profiles. It is important to acknowledge that these findings are derived from the available literature and may not encompass the entirety of research on childhood obesity and early-onset type 2 diabetes mellitus. Furthermore, the limited regional diversity in the selected studies may restrict the generalizability of these findings to other geographic regions. Additional research involving diverse populations is imperative for a comprehensive understanding of the link between childhood obesity and early-onset type 2 diabetes mellitus. Insulin resistance in adipose tissue among obese individuals contributes to the transition from obesity to type 2 diabetes mellitus. Notably, this transition occurs at approximately half the duration in obese youths compared to obese adults, where it typically takes around a decade. The increasing prevalence of childhood obesity and diabetes mellitus in high-income, low-income, and middle-income countries necessitate collective efforts to reduce the increasing rates of early-onset type 2 diabetes in children. This scoping review, therefore, seeks to underscore the importance of early interventions with regard to ensuring a lasting impact capable of extending into adulthood.

Sleep duration and timing are prospectively linked with insulin resistance during late adolescence. Obesity (Silver Spring) 2023; 31:912-922. [PMID: 36847394 PMCID: PMC10033442 DOI: 10.1002/oby.23680] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/12/2022] [Revised: 11/29/2022] [Accepted: 11/29/2022] [Indexed: 03/01/2023]
Abstract
OBJECTIVE The aim of this study was to evaluate whether short sleep duration or later sleep timing is a risk factor for insulin resistance (IR) in late adolescence. METHODS Mexico City adolescents enrolled in a longitudinal birth cohort (ELEMENT) took part in two study visits during peri-puberty that occurred approximately 2 years apart. IR was assessed with serum glucose and insulin. Four groups were defined using puberty-specific cut points: no IR over the follow-up period, transition from normal to IR, transition from IR to normal, and IR at both time points. Baseline sleep assessments were measured with 7-day wrist actigraphy. Multinomial logistic regression models were used to evaluate associations between sleep duration and timing with homeostatic model assessment of insulin resistance categories, adjusting for age, sex, and baseline pubertal status. RESULTS Adolescents who were ≥ 1 hour below the sleep duration recommendations-for-age were 2.74 times more likely to develop IR (95% CI: 1.0-7.4). Similarly, adolescents who were in the latest category of sleep midpoint (>4:33 a.m.) were more likely than those with earliest midpoints (1 a.m.-3 a.m.) to develop IR (odds ratio = 2.63, 95% CI: 1.0-6.7). Changes in adiposity over follow-up did not mediate sleep and IR. CONCLUSIONS Insufficient sleep duration and late sleep timing were associated with development of IR over a 2-year period in late adolescence.

Abstract
BACKGROUND Pre-pregnancy obesity is a well-recognized risk factor for gestational diabetes mellitus (GDM). There is a continuity of obesity from childhood to adolescence and then adulthood. However, it is unknown whether early childhood obesity predicts GDM. METHODS We investigated the prospective association of childhood triceps skinfold thickness and body mass index (BMI) with GDM risk among women from the Mater-University of Queensland Study of Pregnancy (MUSP), a multigenerational cohort study. A multiple logistic regression model was applied to estimate the odds of experiencing GDM by childhood skinfold thickness and BMI. RESULTS Out of 552 women in the study for whom data were available on triceps skinfold thickness and BMI at average age 5 (range 3-7) years old, 52 (9.42%) developed GDM by average age 30 (range 28-33) years. We found that the risk of developing GDM was greater among women who had greater skinfold thickness but not greater BMI at age 5 years. Women who were classified as overweight or obese based on skinfold thickness at age 5 years had an increased odds ratio of GDM compared to women who had normal skinfold thickness. This association remained significant after adjustment for the potential confounders (OR 2.74; 95% confidence interval=1.28-5.86). CONCLUSION The risk of developing GDM was associated with higher skinfold thickness at age 5 years.

Abstract
OBJECTIVE Higher body-mass index (BMI) and lower birth weight (BW) are associated with elevated risk of diabetes in adulthood, but the extent to which they compose two distinct pathways is unclear. METHODS We used data from the National Longitudinal Study of Adolescent to Adult Health, a cohort of adolescents (1994-1995) followed for 14 years over four waves into adulthood (n = 13,413). Sex-stratified path analysis was used to examine pathways from BW [kg; linear (BW) and quadratic (BW2)] to latent trajectories in BMI from adolescence to adulthood to prevalent diabetes or prediabetes (pre/diabetes) in adulthood, adjusting for sociodemographic characteristics. RESULTS Two pathways from BW to pre/diabetes were characterized: one from higher BW to elevated BMI and pre/diabetes and a second from lower BW, independent of BMI. In the BMI-independent pathway, greater BW was associated with marginally lower odds of pre/diabetes in women, but not men. Girls born at lower and higher BW exhibited elevated BMI in adolescence [coeff (95% CI): BW: -2.1 (-4.1, -0.05); BW2: 0.43 (0.09, 0.76)]; higher BW predicted marginally faster BMI gain and higher adolescent BMI and faster BMI gain were associated with pre/diabetes [coeff (95% CI): BMI intercept: 0.09 (0.06, 0.11); BMI slope: 0.11 (0.07, 0.15)]. In boys, BW was weakly associated with BMI intercept and slope; BMI slope, but not BMI intercept, was positively associated with pre/diabetes [coeff (95% CI): 0.29 (0.19, 0.39)]. CONCLUSIONS Findings suggest that in girls, slowing BMI gain is critical for diabetes prevention, yet it may not address distinct pathology stemming from early life.

Abstract
OBJECTIVE To test the hypotheses that an innovative skills-based behavioral family clinic and home-based intervention (LAUNCH) would reduce body mass index z score (BMIz) compared with motivational interviewing and to standard care in preschool-aged children with obesity. STUDY DESIGN Randomized controlled trial with children between the ages of 2 and 5 years above the 95th percentile for body mass index for age and sex recruited from 27 pediatrician offices across 10 recruitment cycles between March 12, 2012 and June 8, 2015. Children were randomized to LAUNCH (an 18-session clinic and home-based behavioral intervention), motivational interviewing (delivered at the same frequency as LAUNCH), or standard care (no formal intervention). Weight and height were measured by assessors blinded to participant assignment. The primary outcome, BMIz at month 6 after adjusting for baseline BMIz, was tested separately comparing LAUNCH with motivational interviewing and LAUNCH with standard care using regression-based analysis of covariance models. RESULTS A total of 151 of the 167 children randomized met intent-to-treat criteria and 92% completed the study. Children were 76% White and 57% female, with an average age of 55 months and BMI percentile of 98.57, with no demographic differences between the groups. LAUNCH participants demonstrated a significantly greater decrease in BMIz (mean = -0.32, SD = ±0.33) compared with motivational interviewing (mean = -0.05, SD = ±0.27), P < .001, ω2 = 0.74 and compared with standard care (mean = -0.13, SD = ±0.31), P < .004, ω2 = 0.75. CONCLUSIONS In preschool-age children, an intensive 6-month behavioral skills-based intervention is necessary to reduce obesity. TRIAL REGISTRATION Clinicaltrials.gov NCT01546727.

Abstract
Difficulties with executive functioning may underlie both overweight and loss of control (LOC) eating behavior across the age spectrum, but there is a relative paucity of research in children with both conditions. This study aimed to characterize general executive functioning among children with overweight and LOC eating as compared to their overweight and normal-weight peers. Participants were 75 racially diverse children (58.7% female; 81.3% African-American), aged 9-12y (M age = 10.5 ± 1.1), of whom 26 were overweight/obese and endorsed LOC eating (OW-LOC), 34 were overweight controls (OW-CON), and 15 were normal-weight controls (NW-CON). All children completed interview-based measures of eating pathology, and behavioral measures of executive functioning. Parents reported on behavioral facets of children's executive functioning. Groups were compared across parent-report measures and behavioral tasks using analyses of covariance (ANCOVAs) and multivariate analyses of covariance (MANCOVAs) which adjusted for general intellectual functioning. Significant group differences were revealed on a behavioral measure of planning, the Tower of London task [F (5,65) = 3.52; p = 0.007], and a behavioral measure of working memory, the List Sorting task [F (2,71) = 6.45; p = 0.003]. Post-hoc tests revealed that OW-LOC and OW-CON performed worse than NW-CON on the Tower of London, with relative decrements in accuracy rather than performance time. Further, OW-LOC performed worse than both OW-CON and NW-CON on the List Sorting task. Overweight with or without concomitant LOC eating in children may characterize a unique pattern of executive dysfunction. Interventions for eating- and weight-related problems in youth should address underlying deficits in planning and working memory.

Abstract
BACKGROUND The increasing incidence of childhood obesity in Asia could be a reflection of early life programming in which environmental/nutritional challenges during pregnancy and first two years of life (the so-called first 1000 days) influence later health. OBJECTIVE OF NARRATIVE REVIEW To assess differences/similarities of anthropometric measures in early life and their influences on metabolic health risk in later life among children in Asia. METHODS Literature search for publication in English using selected key words from Medline (PubMed), Scopus, Science Direct and Google Scholar published from 1994 to October 2014. Some comparisons with Caucasian setting were made when relevant. RESULTS From 152 publications selected for this narrative review, differences in foetal growth and birth weight were deducted between Asian and Caucasian children. Infants in India and Hong Kong had increased fat mass at birth and early infancy as compared to those from other parts of the world. Pre- and during pregnancy conditions influenced birth weight; feeding practices and gender influenced post-natal growth and body composition development. High and low birth weights followed by rapid postnatal growth were linked to increased risks of obesity, insulin resistance and high blood pressure in later life. CONCLUSION Foetal and postnatal growth trajectories are different between countries within and outside Asia. Extremes in birth weight followed by rapid postnatal growth were linked to increased risks of metabolic health of children in this region. As there is limited evidence in Asia, it is important to conduct thorough investigations by using longitudinal studies on early life programming.

The Impact of Acculturation Level on Weight Status and Weight Outcomes in Hispanic Children. J Racial Ethn Health Disparities 2015; 3:582-589. [PMID: 27294753 DOI: 10.1007/s40615-015-0177-9] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2015] [Revised: 10/13/2015] [Accepted: 10/15/2015] [Indexed: 10/22/2022]
Abstract
BACKGROUND Previous studies revealed that higher levels of acculturation are related to obesity in Hispanic adults. Conflicting findings exist regarding this relationship in children, and little is known about the impact of acculturation on children's success in pediatric weight management programs. The purposes of the study were to (1) examine the relationship between acculturation and overweight/obese weight status and (2) determine the impact of acculturation on the changes in weight status among overweight/obese children 12 and 24 months after having participated in a weight management intervention. METHODS This is a secondary analysis of aggregated data from three randomized control trials that occurred between 2005 and 2009. Height, weight, and level of acculturation using the Child Short Scale for Hispanics (C-SASH) were measured in a sample of Hispanic children (n = 559). Logistic regression models were used to study phase 1 (n = 559) and phase 2 (n = 142), controlling for child and family characteristics. RESULTS Children reporting high levels of acculturation had a 52 % lower odds of being overweight or obese. Among overweight/obese children who participated in the intervention, high levels of acculturation demonstrated greater reductions in standardized body mass index (zBMI) at 24 months. CONCLUSIONS The results of this study indicate a need to tailor weight management programs for Hispanic children who have lower levels of acculturation.

Abstract
OBJECTIVE Executive functioning and excess weight have been associated in cross-sectional and prospective studies, but mechanisms explaining this relationship are unclear. The current study aimed to further explore the longitudinal relationship between executive functioning and changes in body weight and to determine whether binge eating behaviors mediate this relationship. METHODS Community-based girls (N = 2450) were assessed by using the behavioral measure of planning, Mazes subtest, and a parent-report measure of impulsivity at age 10; a self-report measure of binge eating at ages 10, 12, and 14; and investigator-measured BMI annually between ages 10 and 16. Regression and bootstrapping analyses explored the relations among age 10 impulsivity and planning, age 12 and age 14 binge eating frequency, and age 10 to 16 BMI changes. RESULTS Age 10 impulsivity and planning each independently predicted age 10 to 16 BMI changes, after accounting for demographics, verbal comprehension, and BMI at age 10 (Ps < .001). Binge eating tendencies at age 12 mediated the relation between age 10 impulsivity and age 10 to 16 BMI changes, after controlling for demographics, verbal comprehension, binge eating frequency, and BMI at age 10 (indirect effect estimate = 0.0007; 95% confidence interval = 0.0001-0.0020). CONCLUSIONS Results support the hypothesis that poorer executive functioning predicts weight gain from middle childhood through adolescence in girls, and that this effect may be partially explained by binge-eating behaviors in early adolescence.

Sanders RH, Han A, Baker JS, Cobley S. Childhood obesity and its physical and psychological co-morbidities: a systematic review of Australian children and adolescents. Eur J Pediatr 2015; 174:715-46. [PMID: 25922141 DOI: 10.1007/s00431-015-2551-3] [Citation(s) in RCA: 154] [Impact Index Per Article: 17.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/13/2015] [Revised: 04/14/2015] [Accepted: 04/16/2015] [Indexed: 12/11/2022]
Abstract
UNLABELLED Australia is predicted to have the highest overweight/obesity rate in the world by 2022 outranking the USA and UK. The purpose of this systematic review was to evaluate the associations between childhood obesity and physical and psychological health co-morbidities. Therefore, a systematic literature search was conducted from six databases (2004-2014). Studies were included if they investigated obesity-related co-morbidities with participants residing in Australia aged 0-18 years. Forty-seven studies fulfilled selection criteria. Evidence suggests that overweight/obese Australian children and adolescents, compared to normal-weight peers, had more cardio-metabolic risk factors and higher risk factors of non-alcohol fatty liver disease and were experiencing more negative psychological outcomes (depression, low self-esteem and lower scores of health-related quality of life). Many other health consequences have either not been investigated in Australia, or as frequently as in other countries. CONCLUSIONS Given Australia's current overweight/obesity prevalence and trajectory, Australia-based studies are needed to identify the suspected co-morbidities, understand the range of individual, social and environmental mechanisms driving obesity, and help identify policies, interventions and strategies that will change the future trajectory and 'disease burden' both in Australia and internationally. WHAT IS KNOWN • Trend analyses have shown that obesity prevalence in Australia is increasing and will outrank UK and the USA by 2022. • Every third Australian child/adolescent between 5 and 19 years old is predicted to be classified as overweight or obese by 2025. • Childhood obesity is associated with multiple immediate physical and psychological health co-morbidities as well as co-morbidities in adulthood. These have often been identified and examined individually. What is New: • This paper presents a holistic picture of childhood obesity and the associated multiple co-morbidities in Australia. • The extensive health-related outcomes from childhood obesity and those requiring further research are identified. • The findings of this paper will influence the development of local/regional, state and national strategies to change Australia's future trajectory.

Abstract
BackgroundThe preschool years are considered critical for establishing healthy lifestyle behaviours such as physical activity. Levels of physical activity track through childhood into adulthood and establishing habitual physical activity early in life is therefore vital. Time spent outdoors is associated with greater physical activity and playground interventions have been shown to increase physical activity in school-aged children. There are few preschool, playground-based interventions and these have given inconclusive results. A report published by the UK’s Chief Medical Officer (CMO) highlighted the need for new interventions to promote movement in the early years (0–5 years).ObjectivesThis study aimed to undertake a pilot cluster randomised controlled trial (RCT) of an outdoor playground-based physical activity intervention for parents and their children aged from 18 months to 4 years (Preschoolers in the Playground or PiP) and to assess the feasibility of conducting a full-scale cluster RCT.DesignThe study was a two-armed pilot cluster RCT with economic and qualitative evaluations. Participants were randomised on a 1 : 1 basis to the PiP intervention (n = 83) or usual practice (control;n = 81).SettingBradford, West Yorkshire, UK.ParticipantsChildren aged from 18 months to 4 years.InterventionThe PiP intervention is grounded in behavioural theory (social cognitive theory) and is in accordance with CMO guidance for physical activity in the early years. It is informed by existing literature and data collected from focus groups with parents. The intervention was delivered in primary school playgrounds. Six 30-minute PiP sessions per week were available for 30 weeks; families were encouraged to come to three a week. The 10-week initiation phase was facilitated by a member of school staff and the maintenance phase was unsupervised.Main outcome measuresRecruitment and retention of schools and families to the trial were the main outcome measures. The acceptability of trial procedures and the intervention, the feasibility of collecting health outcome data and the fidelity of the implementation of the intervention were also evaluated. A preliminary assessment of cost-effectiveness and a sample size calculation for a full trial were conducted.ResultsIn total, 37% of schools and 48% of parents approached agreed to take part. Levels of retention were good at 10 and 52 weeks’ follow-up (82.3% and 83.5% respectively). Both the trial procedures and the intervention were acceptable. However, attendance was low during the autumn and winter/spring initiation phases but somewhat better in the summer initiation phase. Attendance was poor throughout all maintenance phases. The accelerometry protocol for measuring physical activity requires modification. The fidelity of intervention implementation was good (81% adherence). The intervention was borderline cost-effective. A sample size of 600 children from 38 schools is required for a full trial.ConclusionA full RCT of the PiP intervention is feasible. The PiP intervention requires some modification, for example running the intervention during the summer term only, but was found to be acceptable to schools and families.Trial registrationCurrent Controlled Trials ISRCTN54165860.FundingThis project was funded by the NIHR Public Health Research programme and will be published in full inPublic Health Research; Vol. 3, No. 5.

Abstract
OBJECTIVE To examine seasonal variation in weight gain across elementary school (kindergarten-5th grade) among children who are healthy weight, overweight, or obese and from different racial and ethnic groups. METHODS The sample included 7,599 ethnically diverse students ages 5-7 years at baseline (Caucasian: 21.1%, Black: 36.2%, Hispanic: 26.0%, Asian 16.7%). Heights and weights were measured by school nurses at the beginning and end of each school year from kindergarten through the beginning of 5th grade. RESULTS Beginning the summer after 1st grade, all children demonstrated a pattern of standardized BMI (zBMI) increases during the summer (0.04 to 0.09) and zBMI decreases across the school years (-0.06 to 0.00; P<0.0001). Hispanic children and children who were overweight and obese exhibited this pattern in kindergarten while children of other ethnicities and with a healthy weight did not (P<0.0001). CONCLUSIONS Beginning the summer after 1st grade, a consistent pattern of relative weight gain during the summer months (Δ in BMI percentile=1.04) and weight loss during the school year (Δ in BMI percentile=-0.34) emerged. This pattern appeared earlier for children who were overweight, obese, or Hispanic. These findings suggest a need to better understand the causes of the problematic increases in weight during the summer.

Abstract
OBJECTIVE To assess the implications of obstructive sleep apnea (OSA) burden among Indian children. METHODS MonteCarlo simulations were performed in order to estimate the number of OSA related obesity cases among Indian children (1-14 y of age) and the number of cases of stroke, coronary heart disease (CHD) and type 2 diabetes, considered as main adverse outcomes of OSA related childhood obesity, according to untreated and treated [adenotonsillectomy (AT) alone and AT associated to continuous positive airway pressure (CPAP)] pediatric OSA. Data used to perform MonteCarlo simulations were derived from a review about current literature exploring OSA related obesity. RESULTS The analysis on the number of adverse outcomes according to treated and untreated obesity related to OSA showed that treatments reduce the number of obesity cases, resulting in a great reduction of the amount of stroke, CHD and type 2 diabetes cases. However, the cost for treating adverse outcome was higher in patients treated for obesity related to OSA compared to those not receiving any treatment. CONCLUSIONS The reduction in the number of adverse outcomes due to treatment of obesity related OSA implicates the urgent need for public health policies in providing screening for OSA among children population: an early detection and a consequently prompt reaction to pediatric OSA could improve the burden of OSA related obesity.

Abstract
PURPOSE This study evaluated 24-month outcomes of a school-based intensive lifestyle weight management program targeting overweight Mexican-American adolescents. METHODS We recruited a total of 71 adolescents (32 males; 45.1%) between the ages of 10 and 14 years, at or above the 85th percentile for body mass index (BMI). Participants were randomized to a 6-month instructor-led intervention (ILI) or a self-help (SH) program. Both interventions were aimed at modifying eating and physical activity behaviors using behavior modification strategies. We assessed changes in participants' standardized BMI and BMI percentile at baseline, 1, and 2 years. RESULTS Repeated-measures analyses showed that ILI participants showed significantly greater decreases in standardized BMI at 1 and 2 years (F = 8.58, p < .01; and F = 9.27, p < .01, respectively) compared with SH controls. Similar results were found for changes in BMI and BMI percentile. At 2 years, the ILI condition decreased their average BMI percentile by 3.9 percentile points, compared to an increase of 1.6 percentile points in the SH condition. CONCLUSIONS A school-based intervention resulted in improved weight outcomes in overweight Mexican-American adolescents and results were maintained over 2 years.

Abstract
Few studies have simultaneously evaluated multiple levels of influence on whether children walk to school. A large cohort of 4338 subjects from 10 communities was used to identify the determinants of walking through (1) a one-level logistic regression model for individual-level variables and (2) a two-level mixed regression model for individual and school-level variables. Walking rates were positively associated with home-to-school proximity, greater age, and living in neighborhoods characterized by lower traffic density. Greater land use mix around the home was, however, associated with lower rates of walking. Rates of walking to school were also higher amongst recipients of the Free and Reduced Price Meals Program and attendees of schools with higher percentage of English language learners. Designing schools in the same neighborhood as residential districts should be an essential urban planning strategy to reduce walking distance to school. Policy interventions are needed to encourage children from higher socioeconomic status families to participate in active travel to school and to develop walking infrastructures and other measures that protect disadvantaged children.

Abstract
Previous studies show that in many pre-modern and traditional populations the presence of a grandmother correlates with increased child survival rates, maybe as a result of improved child nutrition. Grandmaternal investment aimed at improving grandchildren's nutritional status in subsistence societies may have different outcomes in contemporary affluent societies. Using the British Millennium Cohort Study I investigate the association between maternal and paternal grandmothers' childcare and early years overweight in the UK. Results show that children who were cared for mainly by their grandmothers between the ages of 9 months and 3 years were more likely overweight at age 3 than children who were cared for by their parents. My results are in line with Pearce, Abbas, Ferguson, Graham, and Law (2010) , although they did not distinguish grandmothers by lineage. Grandmothers may influence children's nutritional status in contemporary societies, but as with many evolved behavioral strategies the outcome may be no longer beneficial.

Abstract
Providing effective treatment within a diverse population is complex and difficult. Issues such as a limited amount of time that can be spent with patients and the need to make decisions based on limited information can lead to information processing errors that have a detrimental impact on treatment outcomes. Cognitive biases (e.g., confirmation bias) may further compound this issue by making it less likely that a health care provider will make adjustments to treatment plans. Steps to minimize the potential for cognitive biases are discussed.

Abstract
The objective of this study was to evaluate the evidence on whether childhood obesity is a risk factor for adult disease, independent of adult body mass index (BMI). Ovid MEDLINE (1948-May 2011), EMBASE (1980-2011 week 18) and the Cochrane Library (1990-2011) were searched for published studies of BMI from directly measured weight and height in childhood (2-19 years) and disease outcomes in adulthood. Data were synthesized in a narrative fashion. Thirty-nine studies (n 181-1.1 million) were included in the review. There was evidence for associations between childhood BMI and type 2 diabetes, hypertension and coronary heart disease. Few studies examined associations independent of adult BMI; these showed that effect sizes were attenuated after adjustment for adult BMI in standard regression analyses. Although there is a consistent body of evidence for associations between childhood BMI and cardiovascular outcomes, there is a lack of evidence for effects independent of adult BMI. Studies have attempted to examine independent effects using standard adjustment for adult BMI, which is subject to over-adjustment and problems with interpretation. Studies that use more robust designs and analytical techniques are needed to establish whether childhood obesity is an independent risk factor for adult disease.

Altered glucose homeostasis and hepatic function in obese mice deficient for both kinin receptor genes. PLoS One 2012; 7:e40573.

Abstract
The Kallikrein-Kinin System (KKS) has been implicated in several aspects of metabolism, including the regulation of glucose homeostasis and adiposity. Kinins and des-Arg-kinins are the major effectors of this system and promote their effects by binding to two different receptors, the kinin B2 and B1 receptors, respectively. To understand the influence of the KKS on the pathophysiology of obesity and type 2 diabetes (T2DM), we generated an animal model deficient for both kinin receptor genes and leptin (obB1B2KO). Six-month-old obB1B2KO mice showed increased blood glucose levels. Isolated islets of the transgenic animals were more responsive to glucose stimulation releasing greater amounts of insulin, mainly in 3-month-old mice, which was corroborated by elevated serum C-peptide concentrations. Furthermore, they presented hepatomegaly, pronounced steatosis, and increased levels of circulating transaminases. This mouse also demonstrated exacerbated gluconeogenesis during the pyruvate challenge test. The hepatic abnormalities were accompanied by changes in the gene expression of factors linked to glucose and lipid metabolisms in the liver. Thus, we conclude that kinin receptors are important for modulation of insulin secretion and for the preservation of normal glucose levels and hepatic functions in obese mice, suggesting a protective role of the KKS regarding complications associated with obesity and T2DM.

Abstract
BACKGROUND Recent evidence suggests that the effects of certain food additives may be synergistic or additive. Aspartame (ASP) and Monosodium Glutamate (MSG) are ubiquitous food additives with a common moiety: both contain acidic amino acids which can act as neurotransmitters, interacting with NMDA receptors concentrated in areas of the Central Nervous System regulating energy expenditure and conservation. MSG has been shown to promote a neuroendocrine dysfunction when large quantities are administered to mammals during the neonatal period. ASP is a low-calorie dipeptide sweetener found in a wide variety of diet beverages and foods. However, recent reports suggest that ASP may promote weight gain and hyperglycemia in a zebrafish nutritional model. METHODS We investigated the effects of ASP, MSG or a combination of both on glucose and insulin homeostasis, weight change and adiposity, in C57BL/6 J mice chronically exposed to these food additives commencing in-utero, compared to an additive-free diet. Pearson correlation analysis was used to investigate the associations between body characteristics and variables in glucose and insulin homeostasis. RESULTS ASP alone (50 mg/Kgbw/day) caused an increase in fasting blood glucose of 1.6-fold, together with reduced insulin sensitivity during an Insulin Tolerance Test (ITT) P < 0.05. Conversely MSG alone decreased blood triglyceride and total cholesterol (T-CHOL) levels. The combination of MSG (120 mg/Kgbw/day) and ASP elevated body weight, and caused a further increase in fasting blood glucose of 2.3-fold compared to Controls (prediabetic levels); together with evidence of insulin resistance during the ITT (P < 0.05). T-CHOL levels were reduced in both ASP-containing diets in both genders. Further analysis showed a strong correlation between body weight at 6 weeks, and body weight and fasting blood glucose levels at 17 weeks, suggesting that early body weight may be a predictor of glucose homeostasis in later life. CONCLUSIONS Aspartame exposure may promote hyperglycemia and insulin intolerance. MSG may interact with aspartame to further impair glucose homeostasis. This is the first study to ascertain the hyperglycemic effects of chronic exposure to a combination of these commonly consumed food additives; however these observations are limited to a C57BL/6 J mouse model. Caution should be applied in extrapolating these findings to other species.

Abstract
Rapidly changing dietary practices and a sedentary lifestyle have led to increasing prevalence of childhood obesity (5-19 yr) in developing countries recently: 41.8% in Mexico, 22.1% in Brazil, 22.0% in India, and 19.3% in Argentina. Moreover, secular trends indicate increasing prevalence rates in these countries: 4.1 to 13.9% in Brazil during 1974-1997, 12.2 to 15.6% in Thailand during 1991-1993, and 9.8 to 11.7% in India during 2006-2009. Important determinants of childhood obesity include high socioeconomic status, residence in metropolitan cities, female gender, unawareness and false beliefs about nutrition, marketing by transnational food companies, increasing academic stress, and poor facilities for physical activity. Childhood obesity has been associated with type 2 diabetes mellitus, the early-onset metabolic syndrome, subclinical inflammation, dyslipidemia, coronary artery diseases, and adulthood obesity. Therapeutic lifestyle changes and maintenance of regular physical activity through parental initiative and social support interventions are the most important strategies in managing childhood obesity. Also, high-risk screening and effective health educational programs are urgently needed in developing countries.

Abstract
BACKGROUND Available evidence indicates that the use of antipsychotics, especially second-generation antipsychotics (SGAs), for children with mental health disorders has increased dramatically. Given the demonstrated metabolic and neurological adverse effects seen in adult patients on these medications, detailed evaluation of the risk for these adverse effects in children is appropriate. OBJECTIVE The aim of the study was to assess the evidence for specific metabolic and neurological adverse effects associated with the use of SGAs in children. DATA SOURCES MEDLINE (1996-May 2010) and EMBASE (1996-May 2010) databases were searched using highly sensitive search strategies for clinical trials in a paediatric population (children up to age 18 years). STUDY SELECTION We included any double-blind, randomized controlled trial (RCT) of SGA medications conducted specifically in a paediatric population for the treatment of a mental health disorder. This included the medications risperidone, olanzapine, quetiapine, aripiprazole, clozapine, ziprasidone and paliperidone. The primary outcomes assessed for this review were metabolic and neurological adverse effects, as measured using physical examination manoeuvres, rating scales or laboratory tests. A total of 35 RCTs were included in the analysis, but not all studies had data that could be used in the meta-analysis. DATA EXTRACTION Abstracts retrieved from the searches were reviewed independently by two different reviewers for potential relevant articles. Full-text articles were then read in detail independently by two different reviewers to see if inclusion criteria were fulfilled. Data were extracted independently by two review authors from included studies and entered onto pre-designed summary forms. Clinical trials were evaluated for methodological quality using quality criteria developed by the US Preventive Services Task Force. Based on the fulfilment of quality criteria, studies were rated as good, fair or poor. DATA SYNTHESIS Meta-analysis was performed on the data for synthesis, and was carried out for commonly reported outcomes for each medication individually, in comparison with placebo or another drug. Odds ratios (ORs) with 95% confidence intervals for binary outcomes were used. For continuous outcomes, mean differences were used to analyze the data. Meta-analysis revealed that mean weight gain compared with placebo was highest for olanzapine at 3.47 kg (95% CI 2.94, 3.99) followed by risperidone at 1.72 kg (95% CI 1.17, 2.26), quetiapine at 1.41 kg (95% CI 1.10, 1.81) and aripiprazole at 0.85 kg (95% CI 0.58, 1.13). Olanzapine and clozapine treatment were associated with the highest rate of metabolic laboratory abnormalities in cholesterol and triglycerides. Prolactin elevation occurred with risperidone and olanzapine therapy. Higher odds of extrapyramidal symptoms compared with placebo were seen in children treated with risperidone (OR 3.55; 95% CI 2.04, 5.48) and aripiprazole (OR 3.70; 95% CI 2.37, 5.77). Elevated rates of extrapyramidal symptoms were also experienced with olanzapine use. CONCLUSIONS There is good evidence to support the existence of both metabolic and neurological adverse effects in children treated with these medications. Proper attention and vigilance to potential metabolic and neurological adverse effects is necessary, and should be considered part of the standard of care.

Abstract
Childhood adiposity is increasingly recognized as a significant predictor of cardiometabolic risks in later life. The aim of this study was to investigate factors associated with longitudinal changes in weight during childhood and the development of metabolic disease risk factors. Four hundred twenty-four children from DaQing city, China, were recruited at 5 y old and followed up for 5 y. Birth weight, television (TV) viewing time at 5 y old, blood pressure, anthropometric measurements, fasting plasma insulin (FI), and triglycerides (TG) levels were measured at 5 and 10 y old. Both birth weight and TV viewing time at 5 y old significantly correlated with percentage of ideal weight for height (WFH) at 5 y old (WFH5; p = 0.0032 and p = 0.01), but only TV time was significantly correlated with WFH at 10 y old (WFH10; p < 0.0001). Blood pressures, FI, homeostasis model assessment for insulin resistance (HOMA-IR), and TG at 10 y old were significantly greater in those children who had greater change in WFH from 5 to 10 y old (ΔWFH). We concluded that TV viewing time was the stronger determinant of later childhood adiposity. A greater ΔWFH was associated with increased cardiometabolic risk factors at 10 y old.

Abstract
OBJECTIVE Metformin can decrease adiposity and ameliorate obesity-related comorbid conditions, including abnormalities in glucose homeostasis in adolescents, but there are few data evaluating the efficacy of metformin among younger children. Our objective was to determine whether metformin treatment causes weight loss and improves obesity-related comorbidities in obese children, who are insulin-resistant. RESEARCH DESIGN AND METHODS This study was a randomized double-blind placebo-controlled trial consisting of 100 severely obese (mean BMI 34.6 ± 6.6 kg/m(2)) insulin-resistant children aged 6-12 years, randomized to 1,000 mg metformin (n = 53) or placebo (n = 47) twice daily for 6 months, followed by open-label metformin treatment for 6 months. All children and their parents participated in a monthly dietitian-administered weight-reduction program. RESULTS Eighty-five percent completed the 6-month randomized phase. Children prescribed metformin had significantly greater decreases in BMI (difference -1.09 kg/m(2), CI -1.87 to -0.31, P = 0.006), body weight (difference -3.38 kg, CI -5.2 to -1.57, P < 0.001), BMI Z score (difference between metformin and placebo groups -0.07, CI -0.12 to -0.01, P = 0.02), and fat mass (difference -1.40 kg, CI -2.74 to -0.06, P = 0.04). Fasting plasma glucose (P = 0.007) and homeostasis model assessment (HOMA) insulin resistance index (P = 0.006) also improved more in metformin-treated children than in placebo-treated children. Gastrointestinal symptoms were significantly more prevalent in metformin-treated children, which limited maximal tolerated dosage in 17%. During the 6-month open-label phase, children treated previously with placebo decreased their BMI Z score; those treated continuously with metformin did not significantly change BMI Z score further. CONCLUSIONS Metformin had modest but favorable effects on body weight, body composition, and glucose homeostasis in obese insulin-resistant children participating in a low-intensity weight-reduction program.

Abstract
OBJECTIVE The purpose of this study was to assess which knowledge deficits and dietary habits in an urban pediatric emergency department (ED) population are risk factors for obesity. METHODS This cross-sectional study in an urban pediatric ED used a modified version of the Diet and Health Knowledge Survey, an in-person interview questionnaire, to collect data on demographics, dietary knowledge, and practices. All patients aged 2 to 17 years were enrolled in the study over a 4-month period. Subjects were excluded if they were in extremis, pregnant, incarcerated, institutionalized, considered an emancipated minor, or consumed only a modified consistency diet. RESULTS One hundred seventy-nine subjects were enrolled in this study. Based on body mass index, the prevalence of obesity in our study population was 24%. Parents with obese children answered a mean of 62.9% (95% confidence interval, 60.4%-65.5%) of knowledge questions correctly, whereas all others scored 60.3% (95% confidence interval, 58.3%-62.3%) correctly. Based on the univariate analysis, 10 predictors met inclusion criteria into logistic regression analysis: screen time (P = 0.03), race (P = 0.08), sex (P = 0.04), parental education (P = 0.08), parental estimation that child is overweight (P < 0.0001), parental estimation that child is underweight (P = 0.003), trimming fat from meat (P = 0.06), soft-drink consumption (P = 0.03), exercise (P = 0.07), and chip consumption (P = 0.04). In a multivariate analysis, only male sex, regularly trimming fat from meat, and parental assessment of obesity were independently associated with obesity. CONCLUSIONS Knowledge deficiencies regarding healthy nutrition among parents in an urban pediatric ED population were not significantly associated with having obese children; however, specific habits were. Emergency physicians may provide a valuable role in identification and brief behavioral intervention in high-risk populations during the current epidemic of childhood obesity.

Abstract
OBJECTIVE In adults, higher fasting plasma glucose (FPG) levels, even within the normoglycemic range, are associated with increased diabetes risk. This investigation tested the hypothesis that beta-cell function relative to insulin sensitivity decreases with increasing FPG in youth. RESEARCH DESIGN AND METHODS A total of 223 youth with FPG <126 mg/dl underwent evaluation of first- and second-phase insulin secretion during a 2-h hyperglycemic (approximately 225 mg/dl) clamp, insulin sensitivity during a 3-h hyperinsulinemic-euglycemic clamp, body composition, and abdominal adiposity with dual-energy X-ray absorptiometry and computed tomographic scan. beta-Cell function relative to insulin sensitivity was calculated as the product of first-phase insulin and insulin sensitivity, i.e., glucose disposition index (GDI). The subjects were divided into three FPG categories: <or=90, >90-<100, and >or=100-<126 mg/dl. RESULTS GDI decreased significantly across the three categories as FPG increased (1,086 +/- 192 vs. 814 +/- 67 and 454 +/- 57 mg/kg/min, P = 0.002). This decline remained significant after adjustment for race, sex, BMI, and percent body fat or visceral fat. Within each FPG category, GDI declined with increasing BMI percentiles. CONCLUSIONS The impairment in beta-cell function relative to insulin sensitivity is apparent even within the nondiabetic FPG range in children. At the current cutoff of 100 mg/dl for impaired fasting glucose (IFG), there is an approximately 49% decline in the GDI independent of obesity and race. This observation may reflect a heightened risk of beta-cell dysfunction and progression to diabetes in these children. Considering the near doubling of IFG prevalence among youth between National Health and Nutrition Examination Survey 1999-2000 and 2005-2006, our findings have important public health implications.

Abstract
Antipsychotics are effective at suppressing tics in Tourette syndrome, but can cause side effects. At a single center, all children with Tourette syndrome requiring antipsychotics were systematically monitored for metabolic and neurologic side effects every 6 months. Seventy-three children were followed for a mean of 39.6 months. Most children were treated primarily with an atypical antipsychotic. Thirty-three of 73 children (45%) developed lipid abnormalities. Compared with population-based mean lipid values for boys, total cholesterol, low-density lipoprotein, high-density lipoprotein, and triglyceride levels were significantly higher in our male sample (P < 0.0001). Girls had significantly lower high-density lipoprotein concentrations (P = 0.0033). Thirty-six of 73 (49%) children demonstrated abnormal body mass index percentiles. The odds of having lipid abnormalities were significantly higher in children with abnormal body mass indices (odds ratio, 6.0; 95% confidence interval, 2.15-16.7; P = 0.0004). Three of 73 children developed neurologic complications. Metabolic complications of antipsychotics are common in children. These findings underscore the need to discuss benefits and risks before initiating therapy, and the importance of routinely monitoring growth and lipid profiles. Neurologic complications are uncommon, which is likely attributable to the primary use of atypical antipsychotics in this setting.

Abstract
OBJECTIVE To determine how childhood overweight, in conjunction with other life course weight characteristics, relates to the development of type 2 diabetes in adulthood. RESEARCH DESIGN AND METHODS Among 109,172 women in the Nurses' Health Study II, body fatness at ages 5, 10, and 20 years was assessed by recall using 9-level pictorial diagrams (somatotypes) representing extreme thinness (category 1) to obesity (category 9). Recalled weights at age 18 years and adulthood were used to derive BMI. Self-reported cases of type 2 diabetes were confirmed by supplementary questionnaire. RESULTS Somatotypes at ages 5 and 10 years were positively associated with diabetes risk (P(trend) < 0.0001). The adjusted relative risk (RR) of women with somatotype >or=6 (vs. 2) at age 5 years was 2.19 (95% CI 1.79-2.67) and at age 10 years was 2.57 (2.20-3.01). Increases in size by somatotype or by weight gain since age 18 were associated with increased risk. Compared with women who were never overweight at any age, women who were overweight as an adult (BMI >25 kg/m(2)) but not previously had an adjusted RR of 8.23 (7.41-9.15). The adjusted RR was 15.10 (13.21-17.26) for women who were also overweight at age 10 (somatotype >or=5) and 18 (BMI >25 kg/m(2)). Increased childhood size was not associated with risk among women who did not continue to be overweight in adulthood. CONCLUSIONS Increased body size starting from childhood is associated with a greater risk of diabetes in adulthood. However, women who become lean in adulthood do not have an increased risk.

Abstract
Background The prevalence of obesity and overweight is increasing globally. Frequently coexisting with under-nutrition in developing countries, obesity is a major contributor to chronic disease, and will become a serious healthcare burden especially in countries with a larger percentage of youthful population. 35% of the population of Saudi Arabia are under the age of 16, and adult dietary preferences are often established during early childhood years. Our objective was to examine the dietary habits in relation to body-mass-index (BMI) and waist circumference (W_C), together with exercise and sleep patterns in a cohort of male and female Saudi school children, in order to ascertain whether dietary patterns are associated with obesity phenotypes in this population. Methods 5033 boys and 4400 girls aged 10 to 19 years old participated in a designed Food Frequency Questionnaire. BMI and W_C measurements were obtained and correlated with dietary intake. Results The overall prevalence of overweight and obesity was 12.2% and 27.0% respectively, with boys having higher obesity rates than girls (P ≤ 0.001). W_C and BMI was positively correlated with sugar-sweetened carbonated beverage (SSCB) intake in boys only. The association between male BMI and SSCB consumption was significant in a multivariate regression model (P < 0.0001). SSCB intake was positively associated with poor dietary choices in both males and females. Fast food meal intake, savory snacks, iced desserts and total sugar consumption correlated with SSCB intake in both boys (r = 0.39, 0.13, 0.10 and 0.52 respectively, P < 0.001) and girls (r = 0.45, 0.23, 0.16 and 0.55 respectively, P < 0.001). Older children reported eating significantly less fruit and vegetables than younger children; and less eggs, fish and cereals. Conversely, consumption of SSCB and sugar-sweetened hot beverages were higher in older versus younger children (P < 0.001). BMI and W_C were negatively correlated with hours of night-time sleep and exercise in boys, but only with night time sleep in girls, who also showed the lowest frequency of exercise. Conclusions A higher intake of SSCB is associated with poor dietary choices. Male SSCB intake correlates with a higher W_C and BMI. Limiting exposure to SSCB could therefore have a large public health impact.

Abstract
Using a community-based participatory research approach, we explored adolescent, parent, and community stakeholder perspectives on barriers to healthy eating and physical activity, and intervention ideas to address adolescent obesity. We conducted 14 adolescent focus groups (n = 119), 8 parent focus groups (n = 63), and 28 interviews with community members (i.e., local experts knowledgeable about youth nutrition and physical activity). Participants described ecological and psychosocial barriers in neighborhoods (e.g., lack of accessible nutritious food), in schools (e.g., poor quality of physical education), at home (e.g., sedentary lifestyle), and at the individual level (e.g., lack of nutrition knowledge). Participants proposed interventions such as nutrition classes for families, addition of healthy school food options that appeal to students, and non-competitive physical education activities. Participants supported health education delivered by students. Findings demonstrate that community-based participatory research is useful for revealing potentially feasible interventions that are acceptable to community members.
