Psychometric properties and measurement invariance across gender of the Italian version of the tempest self-regulation questionnaire for eating adapted for young adults. Front Psychol 2022; 13:941784. [PMID: 36059739 PMCID: PMC9435586 DOI: 10.3389/fpsyg.2022.941784] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2022] [Accepted: 07/12/2022] [Indexed: 12/12/2022] Open
Abstract
The prevalence of overweight and obesity in young adults has increased dramatically in recent decades. The unhealthy eating habits that develop at this time can often lead to negative health consequences in the future. It is therefore important to learn about self-regulation and self-control strategies and help young adults to have healthy eating behaviours. This study aims to present an Italian version of the Tempest Self-Regulation Questionnaire for Eating (TESQ-E) adapted for young adults. The instrument assesses self-regulation and self-control strategies to counteract the desire and temptation to eat unhealthy food and to choose healthy foods. A total of 645 students (271 males and 374 females with an average age of 24.82 and SD = 4.34) took part in the study. The results of the confirmatory factor analysis supported the six first-order factors model concerning specific self-regulation strategies and a higher-order structure of the TESQ-E [χ2 (152) = 336.480, p < 0.001; CFI = 0.95; RMSEA = 0.04; SRMR = 0.04]: three correlated second-order factors (addressing the temptation directly, addressing the psychological meaning of temptation, and addressing the goal directly) and one-third-order factor (self-regulatory competence). The results also confirmed the strong measurement invariance of the TESQ-E across gender. To have reliable comparisons across males and females, the latent mean differences tests were performed on the six specific self-regulation strategies. The analysis showed that females appear to prefer strategies that directly address the goal by expressing explicit intentions or plans to eat in a healthy way. Convergence validity was tested through correlations with Eating-Self-Efficacy Brief Scale (ESEBS), Emotional Eating Scale (EES), Scale of Attitudes towards Healthy Eating (SAHE), and Body Mass Index (BMI). In conclusion, the TESQ-E appears to be a psychometrically sound questionnaire that can be effectively used with young adults to measure self-regulation strategies in eating in order to plan personalised interventions for the prevention and control of the metabolic syndrome, and to reduce a wide range of diet-related diseases.

Abstract
In Ghana, the management of hypertension in primary health care is a cost-effective way of addressing premature deaths from vascular disorders that include hypertension. There is little or no evidence of large-scale studies on the prevalence, risk, and knowledge/awareness of hypertension in students aged 12-22 years in Ghana. In a cross-sectional study, blood pressure, anthropometric indices, and knowledge/awareness assessment of students at second-cycle schools were recorded from 2018 to 2020 in three regions of Ghana. Multistage cluster sampling was used in selecting regions and the schools. Prevalence of prehypertension and hypertension was categorized by the Joint National Committee 7, where appropriate, chi-square, scatter plots, and correlations were used in showing associations. A total of 3165 students comprising 1776 (56.1%) females and 1389 (43.9%) males participated in this study within three regions of Ghana. The minimum age was 12 years and the maximum age was 22 years. The mean age was 17.21 with standard deviation (SD: 1.59) years. A 95% confidence interval was set for estimations and a P value < 0.05 was set as significant. The prevalence rate of overall hypertension was 19.91% and elevated (prehypertension) was 26.07%. Risk indicators such as weight, BMI, waist circumference, physical activity, and form of the diet were positively correlated with hypertension. Among Ghanaian students currently in second-cycle educational institutions, 19.91% were hypertensive and 26.07% were prehypertensive. This may indicate a probable high prevalence of hypertension in the future adult population if measures are not taken to curb the associated risks.

Assessment of urinary podocalyxin as a marker of glomerular injury in obesity-related kidney disease in children and adolescents with obesity compared to urinary albumin creatinine ratio. Clin Obes 2021; 11:e12452. [PMID: 33797164 DOI: 10.1111/cob.12452] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/01/2020] [Revised: 02/28/2021] [Accepted: 03/18/2021] [Indexed: 11/29/2022]
Abstract
Obesity increases the risk of chronic kidney disease in children. Our aim was to assess urinary podocalyxin (PCX) in children and adolescents with obesity as a potential marker of obesity-related kidney disease (ORKD). The current case-control study included 128 children with obesity compared to 60 non-obese age and sex matched controls. Study population were subjected to full history taking as well as thorough physical examination. Urine samples for albumin creatinine ratio (uACR) and PCX were collected from the study population as well as blood samples for assessment of serum creatinine and fasting lipid profile. A statistically significant difference was found between cases and controls regarding urinary PCX (P < .001) and uACR (P = .021). A statistically significant positive correlation was found between uACR and weight SD score (SDS), body mass index SDS, waist circumference, estimated glomerular filtration rate, triglycerides (TG) as well as urinary PCX, whilst urinary PCX correlated significantly with obesity duration and uACR. Cases with microalbuminuria had a statistically significant higher waist circumference, waist-hip ratio, fat percentage, TG and urinary PCX compared to those with normal uACR (P = .042, .034, .05, .018 and .036 respectively). Urinary PCX showed 83.3% sensitivity and 74% specificity in detection of albuminuria. Urinary PCX was increased significantly in children with obesity making it a potential sensitive marker of ORKD in children.

Abstract
Background. Hypertension (HTN) is the second main source of outpatient morbidity in Ghana, and the understanding of a disease is necessary for its prevention and management. Language and communication are contributing factors to HTN in Ghana. No studies have been conducted to assess knowledge/awareness of HTN (in the context of its understanding) among students in Ghana. Following a local name for HTN in Ghana, researchers interviewed students through a focus group to assess their understanding/perception (meaning, cause, and prevention) of the disease. Available literature has concerned itself with clients' knowledge of their condition (diagnosis) rather than their comprehension of the true nature of what HTN is. The objective of this study is to assess the knowledge/awareness of HTN in the context of its understanding of the meaning, perception, causes, and prevention of hypertension among students of Ghana's Senior High School (Second Cycle). Semistructured interviews with the use of the theme lists were employed. Focus group conversations and interviews were held in the local Akan (Twi) language, which was later translated, interpreted, and analyzed. Overall, 25 second-cycle students participated. 60% were between 15 and 17 years, 24% were ≥18 years, and 16% were <15 years of age. Males were 44% and females were 56%. Students gave diverse perceptions of their knowledge of HTN. The local language's translation of HTN has influenced and affected its meaning/understanding among some, thus affecting their perception of causes and prevention.

Abstract
AIM This study aimed to investigate the association between carotid intima-media changes that play a part in the atherosclerotic process in childhood obesity and fibrin monomers as an important indicator of fibrin plaque. METHODS This is a cross-sectional study of obese children and non-obese healthy control subjects. Height, weight, body mass index, waist/hip ratio, systolic/diastolic blood pressures were recorded, in addition, biochemistry, haemogram, fibrin monomers and d-dimer were measured in both groups. Right and left common carotid intima-media thicknesses were measured by ultrasonography and mean carotid intima-media thickness was calculated. RESULTS Obese children (n = 89, 46.1% girls, median age: 12.6 ± 2.3 years) and healthy control group (n = 40, 52.5% girls, median age: 13.2 ± 2.2 years) were comparable in terms of gender, age and puberty stage. Mean carotid intima-media thickness was higher in obese children than the healthy control group (P = .002). There was no difference between the two groups in terms of fibrin monomers and d-dimer levels. In obese children, there was a weak negative correlation between mean carotid intima-media thickness and fibrin monomers (P = .030, r = -0.233). CONCLUSION In obese children, mean carotid intima-media thickness was determined higher, as an early indicator of atherosclerosis. We want to emphasise that obese children are at risk for cardiovascular disease and should be evaluated in terms of atherosclerosis. This study investigates the relation between increased carotid intima-media thickness and fibrin monomers, in children, the first time in Literature.

Abstract
IMPORTANCE Antibiotic exposures in early life may affect weight by altering gut microbiota, potentially increasing the likelihood of childhood obesity. OBJECTIVE To examine whether repeated antibiotic exposure by age 48 months is associated with higher body mass index (BMI) at age 54 months. DESIGN, SETTING, AND PARTICIPANTS This research was undertaken within a prospective cohort study in New Zealand (Growing Up in New Zealand) that recruited 6853 children antenatally during 2009 to 2010. At the 54-month follow-up, 5734 of 6156 children (93%) had their weight and height measured. Community pharmacy antibiotic dispensing data were obtained from the New Zealand Pharmaceutical Collection database for children whose parents consented to external data linkage. The analytic sample comprised singletons with 54-month weight and height measurements, community antibiotic dispensing and birth weight data, gestational age greater than 27 weeks, and no congenital anomalies. Data analysis took place from 2017 to 2018. EXPOSURES Antibiotic exposure (yes or no), the number of dispensings, age at first exposure, and timing (age) of exposures between birth and age 48 months. MAIN OUTCOMES AND MEASURES World Health Organization BMI-for-age z scores; and International Obesity Task Force overweight and obesity cutoff points that pass through adult BMI values of 25 and 30. RESULTS Of the 5128 singletons (2622 [51%] male; mean [SD] birth weight of 3527 [542] g), 4886 (95%) had an antibiotic prescription by age 48 months and 437 (9%) had obesity at age 54 months. Adjusted mean (SE) BMI-for-age z scores increased significantly with the number of antibiotic dispensings for 4 to 6, 7 to 9, and more than 9 dispensings (unexposed, 0.87 [0.09]; 1-3 exposures, 0.92 [0.06] [P = .57]; 4-6 exposures, 1.06 [0.06] [P = .02]; 7-9 exposures, 1.06 [0.06] [P = .02]; >9 exposures, 1.08 [0.05] [P = .01]). Additionally, receiving more than 9 dispensings was associated with greater likelihood of obesity compared with no exposure (adjusted odds ratio, 2.41; 95% CI, 1.07-5.41). Children whose exposure began in the first year of life had a higher adjusted mean (SD) BMI-for-age z score than those not exposed (1.06 [0.05] vs 0.89 [0.09]; P = .03), whereas those whose exposure commenced after the first year of life did not (1.02 [0.06] vs 0.89 [0.09]; P = .10). CONCLUSIONS AND RELEVANCE In this study, repeated antibiotic exposure in early childhood was associated with higher mean BMI-for-age z score and an increased likelihood of obesity. Future research could examine whether interventions such as antibiotic stewardship programs, which are designed to reduce overprescribing of antibiotics, also reduce early childhood obesity.

Abstract
OBJECTIVE: To determine the prevalence of overweight and obesity in Algerian adolescents and investigate the associated cardiometabolic complications. METHODS: The study was conducted in the city of Constantine (Algeria). The population included 1100 schooled adolescent, aged 12–18 years, randomly selected. All had anthropometric measurements, and 989 had blood tests. The BMI was calculated and the prevalence of overweight and obesity was determined using the International Obesity Task Force reference values. RESULTS: 179 (16.3%) adolescents were overweight including 74 boys (13.8%) and 105 girls (18.6%), 51 (4.6%) adolescents were obese including 25 (4.6%) boys vs 26 (4.6%) girls (p = 0.09). Overweight and obese adolescents had higher systolic blood pressure/diastolic blood pressure (p = 0.001/p < 0.0001) and abnormal blood lipid levels. Furthermore, the HOMA index was higher in overweight and obese adolescents (p < 0.0001). CONCLUSION: These findings show a high prevalence of overweight and obesity in a population of Algerian adolescents leading to significant cardiometabolic abnormalities.

Longer duration of obesity is associated with a reduction in urinary angiotensinogen in prepubertal children. Pediatr Nephrol 2017; 32:1411-1422. [PMID: 28337615 DOI: 10.1007/s00467-017-3639-y] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/29/2016] [Revised: 02/27/2017] [Accepted: 02/27/2017] [Indexed: 12/13/2022]
Abstract
BACKGROUND We aimed to study the impact of obesity on urinary excretion of angiotensinogen (U-AGT) in prepubertal children, focusing on the duration of obesity and gender. Also, we aimed to evaluate whether plasma angiotensinogen (P-AGT) and hydrogen peroxide (H2O2) play a role in the putative association. METHODS Cross-sectional evaluation of 305 children aged 8-9 years (160 normal weight, 86 overweight, and 59 obese). Anthropometric measurements and 24-h ambulatory blood pressure monitoring were performed. Angiotensinogen (AGT) was determined by a commercial enzyme-linked immunosorbent assay (ELISA) kit and H2O2 by a microplate fluorometric assay. RESULTS U-AGT and P-AGT levels were similar across body mass index (BMI) groups and between sexes. However, boys who were overweight/obese since the age of 4 years presented lower levels of U-AGT compared with those of normal weight at the same age. In children who were overweight/obese since the age of 4, urinary H2O2 decreased with P-AGT. CONCLUSIONS A higher duration of obesity was associated with decreased U-AGT in boys, thus reflecting decreased intrarenal activity of the renin-angiotensin system. Also, children with a longer duration of obesity showed an inverse association between urinary H2O2 and P-AGT. Future studies should address whether these results reflect an early compensatory mechanism to limit obesity-triggered renal dysfunction.

Abstract
BACKGROUND Obesity is defined as an abnormal or excessive accumulation of body fat and it is currently one of the most concerning public health issues, as it is related to a wide range of serious diseases and disorders. The study of the causes of obesity is multifactorial, and its diagnosis requires specific methods. Its management is complex, and it is crucial that it is handled appropriately, and its primary focus should be on prevention through lifestyle changes.The objectives of this study are to determine the prevalence of overweight/obesity in adolescents of both genders, aged 10 to 12 years, from different geographical environments (rural and urban), as well as to identify the underlying risk factors related to the respective obesity rates, namely: family environment, eating habits, and physical exercise. METHODS An observational, cross-sectional study in a sample of 129 adolescents aged 10 to 12 years was conducted. Participants of both genders from rural and urban environments were included in this study. A questionnaire was completed on eating habits and physical activity, focusing on the number of daily meals, meal composition, and sedentary lifestyle habits. An anthropometric assessment was also performed, including weight, height, skinfolds, waist circumference, arm circumference, and percentage of lean mass and body fat, using bioelectrical impedance analysis. RESULTS In the rural environment, the obesity rate was 16.9%, with 26.8% being either overweight or obese; whereas in the urban environment, these rates were respectively 16.7% and 33.4%. Living in a rural environment was not an independent predictor of being overweight or obesity, p = 0.581, or for increased percentage of body fat, p = 0.790. In contrast, being 12 years old, eating high-calorie foods four times a week or less, and having at least one obese parent were predictors of being overweight or obesity. Being 12 years old was also a predictor of gaining moderate to high body fat. CONCLUSIONS Adolescents' residence in a rural or urban environment does not affect the occurrence of being overweight, obesity or high body fat. Paternal obesity was an important predictor of obesity in children. Obese fathers tended to serve higher calorie meals to their children.

Abstract
BACKGROUND Childhood obesity is one of the important risk factors for early atherosclerosis. We aimed to evaluate the effect of obesity on abdominal aortic intima media thickness (aaIMT) in children. METHODS We consecutively recruited 60 obese and 28 healthy children from the outpatient clinic of pediatrics. In all patients, BMI, waist circumference (WC) and hip circumference (HC) were measured, and fasting serum lipid profile, plasma glucose and plasma insulin were studied. Homeostasis model assessment-estimated insulin resistance (HOMA-IR) was calculated for the obese group. All children underwent ultrasonography to evaluate hepatosteatosis and to measure aaIMT. RESULTS There was a significant difference between the groups in terms of aaIMT, insulin, glucose, HOMA-IR, total cholesterol, low-density lipoprotein, triglyceride and hepatosteatosis. aaIMT was 1.12 ± 0.25 and 0.61 ± 0.18 mm in the obese and nonobese groups, respectively (p < 0.001). In the obese group, there was a positive correlation between aaIMT and WC, WC/height ratio, BMI, HC and hepatosteatosis (p < 0.05 for all), with the highest significance for WC. CONCLUSIONS This study showed that aaIMT was significantly higher in obese children than in nonobese children, and that WC was a strong predictor for aaIMT. Early detection of an increased aaIMT in obese children may guide the follow-up of these patients in terms of developing atherosclerosis and its complications.

Abstract
BACKGROUND AND OBJECTIVE The high prevalence of obesity in the pediatric age groups draws attention to lifestyle factors including diet and physical activity. Data on obesity in adolescents and their snacking behavior are conflicting. This study aimed to assess the association of snacking behavior and obesity among female adolescents in Isfahan, Iran. SUBJECTS AND DESIGN This cross-sectional study was carried out on 265 female Isfahanian students who were chosen by systematic cluster random sampling. Dietary intake was assessed using a validated self-administered semiquantitative food frequency questionnaire that included 53 food items. Snacking behavior was defined by healthy snack score in combination with the frequency of snack intake. RESULTS Individuals who consumed more healthy snacks and those with snacking frequency of 4 times a day or more had significantly lower weight, body mass index (BMI), and waist circumference (p < 0.001). Decreased consumption of healthy snacks was significantly associated with a greater chance of being overweight, generally obese, and abdominally obese among adolescents (odds ratio [OR] = 1.98; 95% confidence interval [CI], 1.00-3.14, ptrend = 0.04 and OR = 2.10; 95% CI, 1.01-3.13, ptrend = 0.04, respectively). Frequency of snack intake was inversely related to overweight, general obesity, and abdominal obesity (OR = 3.23; 95% CI, 1.73-5.61, ptrend = 0.03 and OR = 1.84; 95% CI, 1.05-3.20, ptrend = 0.04, respectively). Healthy snack score in combination with frequency of snacking showed that those in the lowest tertile of snacking who consumed snacks less than 4 times/day had the highest risk of obesity compared to other categories (OR = 2.09, 95% CI, 1.11-3.20, p < 0.001). CONCLUSION More frequent consumption of healthy snacks is associated with decreased prevalence of overweight, general obesity, and abdominal obesity in adolescents. Further studies, in particular of a prospective nature, are required to examine this association in other populations.

Abstract
AIM The aim of the study was to document long term trends in oral antidiabetic drug (OAD) use among children and adolescents in the Netherlands. METHODS A population-based cohort study was conducted using the Dutch PHARMO Database Network. All patients younger than 20 years old with at least one OAD dispensing were identified. Age-adjusted and age-specific incidence (1999-2011) and prevalence (1998-2011) rates of OAD use were calculated. Trends over time were assessed using joinpoint regression software. A subset of PHARMO Database Network (including community pharmacy dispensing records linked to general practitioner data (OPD-GP database)) was used to assess indications for OADs. RESULTS In 2011, the overall age-adjusted incidence and prevalence rates of OAD use were 20.7/100 000 (95% CI 19.2, 22.1) person-years (PY) and 53.8/100 000 (95% CI 51.5, 56.1) persons, respectively. The average annual percentage change (AAPC) in the overall age-adjusted incidence rates from 1999 to 2011 was 18.9% (95% CI 4.5, 35.2). The incidence and prevalence rates of OAD use were higher among females and older age categories. The increases in rates of OAD use were mainly driven by metformin. For only 50% of the 98 patients in the OPD-GP database, indications for OAD prescriptions were reported with type 1 diabetes (n = 20), type 2 diabetes (n = 16), and overweight/obesity (n = 10). CONCLUSIONS Incidence and prevalence rates of OAD use in children and adolescents substantially increased in the Netherlands, especially among older age categories (10-14 and 15-19 years) and females. The main indications for use of OADs were type 1 and 2 diabetes and overweight/obesity.

Abstract
OBJECTIVE Physicians' awareness about pediatric health problems is very important in health system. This has not been investigated in Iran as yet. Therefore this study was conducted to characterize the knowledge of the Iranian physicians which has direct association with health status of children. METHODS One hundred and four physicians, mainly pediatric specialists (58.6%) working in the state hospitals (45.1%) were enrolled. They filled a valid and reliable questionnaire, containing 26 questions about basic and important pediatric issues before and after an educational pediatric program (EPP). Findings : Thirty nine (37.5%) physicians answered correctly more than 2/3 of all questions (passed the examination) before EPP, which increased to 42.3% after EEP. Subgroup analysis showed that the total scores of general practitioners (P=0.007) was significantly increased after the EPP. Moreover, physicians with shorter practicing time (P=0.006) and those with shorter time past graduation (P=0.01) had a significant improvement in their total scores after the program. The best scores of educational issues were documented in growth and development (16.0%; P=0.04), followed by dermatology (9.2%, P=0.04), urology (9.1%; P=0.04), and asthma and allergy (9.0%, P=0.04). CONCLUSION This study revealed that there are gaps in the knowledge of professionals about the pediatric issues.

Abstract
Nutrition during adolescence influences long-term health outcomes. Consumption of fish has many health benefits, yet few studies have investigated associations between fish intake and nutrient intake and lifestyle factors in adolescents. A cross-sectional study utilizing 24-hour dietary recalls obtained by in-person interviews investigated relationships between fish intake and demographic characteristics, nutrient intake, and lifestyle factors among adolescents (mean age = 15.5 years). Height, weight, and self-administered survey data were collected from 839 high school students who took part in the 2000-2004 Hawaii Nutrition Education Needs Assessment survey. About 8.5% of the students consumed fish, based on estimated EPA (eicosapentaenoic acid) + DHA (docosahexaenoic acid) intakes. Adolescents who consumed fish had higher intake of protein, water, B vitamins, magnesium, selenium, and zinc but consumed more calories, fat, saturated fat, and sodium. Considering the school health program's potential to reach adolescents, more intensive school-based interventions can be directed to promote safe fish consumption and to encourage other positive lifestyle behaviors.

Abstract
BACKGROUND Childhood obesity gives rise to health complications including impaired musculoskeletal development that associates with increased risk of fractures. Prevention and treatment programs should focus on nutrition education, increasing physical activity (PA), reducing sedentary behaviours, and should monitor bone mass as a component of body composition. To ensure lifestyle changes are sustained in the home environment, programs need to be family-centered. To date, no study has reported on a family-centered lifestyle intervention for obese children that aims to not only ameliorate adiposity, but also support increases in bone and lean muscle mass. Furthermore, it is unknown if programs of such nature can also favorably change eating and activity behaviors. The aim of this study is to determine the effects of a 1 y family-centered lifestyle intervention, focused on both nutrient dense foods including increased intakes of milk and alternatives, plus total and weight-bearing PA, on body composition and bone mass in overweight or obese children. METHODS/DESIGN The study design is a randomized controlled trial for overweight or obese children (6-8 y). Participants are randomized to control, standard treatment (StTx) or modified treatment (ModTx). This study is family-centred and includes individualized counselling sessions on nutrition, PA and sedentary behaviors occurring 4 weeks after baseline for 5 months, then at the end of month 8. The control group receives counselling at the end of the study. All groups are measured at baseline and every 3 months for the primary outcome of changes in body mass index Z-scores. At each visit blood is drawn and children complete a researcher-administered behavior questionnaire and muscle function testing. Changes from baseline to 12 months in body fat (% and mass), waist circumference, lean body mass, bone (mineral content, mineral density, size and volumetric density), dietary intake, self-reported PA and sedentary behaviour are examined. DISCUSSION This family-centered theory-based study permits for biochemical and physiological assessments. This trial will assess the effectiveness of the intervention at changing lifestyle behaviours by decreasing adiposity while enhancing lean and bone mass. If successful, the intervention proposed offers new insights for the management or treatment of childhood obesity. TRIAL REGISTRATION ClinicalTrials.gov, NCT01290016.

Abstract
There is a paucity of detailed information about the role of childhood food patterns or on the impact of individual nutrients on adulthood cardiovascular disease (CVD). We review here the reports that have investigated these questions in the Young Finns Study with its 3596 subjects at baseline, aged 3 to 18 years. All the participants filled in a food habit questionnaire, and half of them provided a 48-hour dietary recall interview. In adulthood, cardiovascular risk factors as well as structural and functional markers of subclinical atherosclerosis were measured, i.e. carotid artery intima media thickness (IMT), and measurements of arterial elasticity and brachial artery endothelial function. Our data demonstrate that dietary patterns can already be identified in childhood. These patterns remain relatively stable over the life-course and associate with cardiovascular risk factors and vascular markers of subclinical atherosclerosis. For example, a traditional dietary pattern characterized by low intakes of fruits and vegetables was associated with elevated increased adulthood IMT especially in men, whereas a diet with a high intake of vegetables was independently associated with increased arterial elasticity in both genders. Our findings and the current literature suggest that childhood nutrition has a significant role in the progression of CVD.

Abstract
BACKGROUND Inconsistent relationships between weight and psychosocial functioning may be due to discrepancies between objective measures of weight and children's perceptions of weight. The current study compared the predictive validity of actual versus perceived weight in children to determine which is the strongest predictor of psychosocial functioning. METHODS Ninety-eight youth (ages 8-17) completed measures of perceived weight and psychosocial functioning (i.e., depressive symptoms, peer victimization, and self-esteem) while attending a well-child visit. Height and weight were obtained from the medical record and used to classify children as healthy weight, overweight, or obese. Actual and perceived weight percentiles were entered simultaneously in regression analyses predicting psychosocial functioning. RESULTS A disproportionate number of overweight (70%) and obese (40.6%) youth reported a perceived weight in the healthy range (below 85(th) BMI percentile). Perceived weight was predictive of depressive symptoms whereas actual weight was not. No relationship between weight (perceived or actual) was found for peer victimization or self-esteem. CONCLUSIONS Weight underestimation is common in children, particularly among youth who are overweight and obese. Perceived, but not actual, weight was predictive of depressive symptoms, highlighting the importance of weight perceptions among youth across the weight spectrum.

Abstract
This ancillary, descriptive correlational study examined the effect of glucose regulation, blood pressure (BP), and their combined effects on cardiac autonomic function in 128 overweight-obese 11-18-year-olds. Measures included body mass index, resting BP, fasting glucose, glucose tolerance, and cardiac autonomic function (heart rate variability, QT, and Cornell voltage). After adjusting for age and gender, multivariate analysis of covariance revealed no differences in cardiac autonomic measures based on glucose regulation (p = .319), BP (p = .286), or the interaction between glucose regulation and BP (p = .132). The additive effect of prediabetes and elevated BP did not impact cardiac autonomic function in overweight-obese youth.

Abstract
Objective.
n-3 long-chain polyunsaturated fatty acids (LCPUFAs) have shown potential to increase lipid oxidation and prevent obesity. Subjects. Seventy-eight boys aged 13–15 y with whole-body fat% of 30 ± 9% were randomly assigned to consume bread with fish oil (FO) (1.5 g n-3 LCPUFA/d) or vegetable oil for 16 weeks. All boys were counselled to improve diet and exercise habits. Results. Lifestyle counselling resulted in decreased sugar intake but did not change the physical activity level. Whole-body fat% decreased 0.7 ± 2.5% and 0.6 ± 2.2%, resting metabolic rate after the intervention was 7150 ± 1134 kJ/d versus 7150 ± 1042 kJ/d, and the respiratory quotient was 0.89 ± 0.05 versus 0.88 ± 0.05, in the FO and control group, respectively. No group differences were significant. Conclusion. FO-supplementation to slightly overweight teenage boys did not result in beneficial effects on RMR, lipid oxidation, or body composition.

Abstract
Obesity is a major public health problem affecting adults and children in both developed and developing countries. This condition often leads to metabolic syndrome, which increases the risk of cardiovascular disease. A large number of studies have been carried out to understand the pathogenesis of cardiovascular dysfunction in obese patients. Endothelial dysfunction plays a key role in the progression of atherosclerosis and the development of coronary artery disease, hypertension and congestive heart failure. Noninvasive methods in the field of cardiovascular imaging, such as measuring intima-media thickness, flow-mediated dilatation, tissue Doppler, and strain, and strain rate, constitute new tools for the early detection of cardiac and vascular dysfunction. These techniques will certainly enable a better evaluation of initial cardiovascular injury and allow the correct, timely management of obese patients. The present review summarizes the main aspects of cardiovascular dysfunction in obesity and discusses the application of recent noninvasive imaging methods for the early detection of cardiovascular alterations.

Abstract
OBJECTIVE To investigate the relationships of cardiorespiratory fitness (CRF) and physical activity (PA) with the risk of overweight/obesity in Chinese schoolchildren. METHODS A total of 1795 children aged 8-13 years at baseline were followed-up for 18 months from 2006 to 2008 in Guangzhou, China. Children were categorized as "normal weight", "overweight", and "obese" using Chinese obesity cut-off points. Data on self-reported PA were obtained. CRF was determined by the 20-meter multistage fitness test, and the sex-specific median values were set as the cut-off points for the classification of high and low CRF. RESULTS Significantly higher CRF was found in children with normal weight (from 6.55 to 8.65 ml/kg/min) or physically active children (from 0.42 to 1.22 ml/kg/min) compared with the reference group. CRF was inversely associated with the kg/m(2) change in BMI during the follow-up period (β=-0.63 kg/m(2) and -0.64 kg/m(2) for boys and girls, respectively, both p<0.001). Significant association of baseline CRF with overweight/obesity was found in boys (odds ratio (OR) 8.71; 95% confidence interval (CI) 2.59-29.26, p<0.001), whereas the association was marginally insignificant in girls (OR 6.87; 95% CI 0.96-49.09, p=0.055). CONCLUSIONS The results showed a strong negative association between CRF levels and children's BMI and weight gain.

It was detected that 2.2% of the population in the study was obese; 2.1% of males and 2.3% of females. While the prevalence of obesity was extremely low before 9 ages and after 15, it reached to high values at puberty and just before pubertal period in boys. The prevalence of overweight was higher in girls and reached to peak point at pubertal ages. Generally, the prevalence of obesity and overweight was slightly higher in girls than in boys, although the boys were more obese in prepubertal ages. CONCLUSION Overweight and obesity are concerns for children and adolescents in low socio-economic status regions as well.

Abstract
Hypertension is a global problem, affecting both developed and developing nations. In addition to being a major cause of morbidity and mortality, hypertension places a heavy burden on health care systems, families, and society as a whole. Despite evidence of an increasing prevalence of hypertension among youth, the consequences of early onset are poorly established and often overlooked. Childhood hypertension is often asymptomatic and easily missed, even by health professionals. Target organ damage is detectable in children and adolescents, however, and hypertension continues into adulthood. Additional strategies to improve cardiovascular health among children and adolescents are needed, including methods to achieve healthy lifestyles at home and in school, improved systems for diagnosis, and research on mechanisms and timing of interventions. The burden of hypertension in the young will continue to grow unless it is given the attention it deserves by policy makers, health care providers, schools, parents, and society. This report aims to increase awareness of the problem of hypertension in childhood. Recent reports on prevalence and target organ injury are discussed and health policy initiatives to improve blood pressure control are proposed.

[PMID: 20633586 DOI: 10.1016/j.appet.2010.07.005] [Citation(s) in RCA: 47] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2009] [Revised: 06/24/2010] [Accepted: 07/05/2010] [Indexed: 01/28/2023]
Abstract
There is a critical need to identify risk factors that make parents more likely to restrict their child's food intake. Child weight and ethnicity, parent weight, parent body dissatisfaction, and parent concern of child weight were examined as correlates of parent use of restrictive feeding practices in a diverse sample of 191 youth (ages 7-17). Participants attending a pediatric outpatient visit completed the Child Feeding Questionnaire (parent feeding practices and beliefs), the Figure Rating Scale (body dissatisfaction) and a demographic form. Parent BMI and child degree of overweight were calculated. Parent use of restrictive feeding practices was positively associated with parent BMI and was moderated by parent body dissatisfaction. Parent concern of child weight mediated the relationship between increasing child degree of overweight and parent use of restrictive feeding practices. There were no differences by child gender or ethnicity in parent use of restrictive feeding practices. These preliminary findings highlight the importance of assessing for underlying parent motivations for utilizing restrictive feeding practices and may help to identify and intervene with families at-risk for engaging in counterproductive weight control strategies. Continued identification of correlates of parent use of restrictive feeding practices is needed across child development and among individuals from diverse backgrounds.

Abstract
BACKGROUND Pedometry methods for collecting data in young populations are advancing, but it is unclear how many days of data are enough for population monitoring. METHODS Using random-digit dialing, 11,669 5- to 19-yr-olds were recruited into the Canadian Physical Activity Levels among Youth study and mailed a data collection package. Pedometers were worn for 7 d, and steps counts were logged daily. Reactivity was assessed by examining estimates from the pattern of pedometer data across days (arranged from first day of collection to last) using a repeated-measures ANOVA. Intraclass correlations (ICC) were computed for the first day and consecutive additional days (compared with the criterion estimate based on the whole week) to determine the minimal number of days required to achieve a reliability ICC of 0.70, 0.80, and 0.90. RESULTS Most children (990%) wore the pedometer for 7 d. Mean steps per day differed across consecutive days (F = 52.7, P = 0.000); however, no difference occurred between the first and the second day of monitoring. Furthermore, no difference was observed between the first and either the third or the fourth day when monitoring commenced on a Monday or a Tuesday. Therefore, there was no clear evidence of reactivity. The first day provided a good representation of steps per day relative to the whole week in terms of both reliability (ICC = 0.79) and validity (relative absolute percent error [APE] =2.5%), and these improved with additional days (2 d, ICC > 0.85; > or = 3 d, ICC > 0.90; and > or = 3 d, APE < 1%). CONCLUSIONS The Canadian Physical Activity Levels among Youth demonstrates the feasibility of national surveillance of physical activity using pedometers.Two days are sufficient to determine steps per day, and a single day appears defensible in terms of population monitoring if minimal standards for reliability are acceptable.

Abstract
UNLABELLED Increased rates of obesity among youth in the last several decades have led to the emergence of several health problems. Declining physical activity is also contributing to this trend. OBJECTIVE To evaluate the dietary habits and physical activity in youth. METHODS 177 Greek students participated in the present study. Interviews were performed using a structured questionnaire. RESULTS Of the participants, 80.2% were normal weight individuals, 18.6% were overweight, and 1.2% was obese. Of the normal weight participants, 72.5% ate breakfast on a daily basis, and 45.5% of the overweight individuals ate breakfast irregularly. Among the respondents, 88% underlined the impact of life style on their nutritional status, 17% actually exercised or played sports > 20 minutes per day, 20.3% reported asthma, and 83.3% with asthma were overweight. CONCLUSIONS A substantial proportion of young people engaged in health risk behaviors associated with obesity, diabetes, and asthma. Adoption of healthy lifestyles could prevent the risk for chronic disease.

Abstract
BACKGROUND Physical activity is assumed to reduce excessive fatness in children. This study examined whether the benefits of early childhood moderate-to-vigorous physical activity (MVPA) on fatness are sustained throughout childhood. METHODS MVPA minutes per day (min/d) and fat mass (kilograms; kg) were measured using accelerometry and dual-energy x-ray absorptiometry in 333 children aged 5, 8, and 11 years who were participating in the Iowa Bone Development Study. Mixed regression models were used to test whether MVPA at age 5 years had an effect on fat mass at age 8 years and age 11 years, after adjustment for concurrent height, weight, age, maturity, and MVPA. The analysis was repeated to control for fat mass at age 5 years. Using mixed-model least-squares means, adjusted means of fat mass at age 8 years and age 11 years were compared between the highest and lowest quartiles of MVPA at age 5 years. Data were collected between 1998 and 2006 and analyzed in 2008. RESULTS For boys and girls, MVPA at age 5 years was a predictor of adjusted fat mass at age 8 years and age 11 years (p<0.05). In girls, the effect of MVPA at age 5 years was not significant when fat mass at age 5 years was included. Boys and girls in the highest quartile of MVPA at age 5 years had a lower fat mass at age 8 years and age 11 years than children in the lowest MVPA quartile at age 5 years (p<0.05; mean difference 0.85 kg at age 8 years and 1.55 kg at age 11 years). CONCLUSIONS Some effects of early-childhood MVPA on fatness appear to persist throughout childhood. Results indicate the potential importance of increasing MVPA in young children as a strategy to reduce later fat gains.
