Abstract
Eating behavior and physical activity behavior are under the control of certain cognitive patterns. 6600 adults and 4400 children/adolescents (8-18 years) were tested with the Obesity Diagnostics and Evaluation System (AD-EVA). Potentially significant gender differences will be detailed for the entire juvenile cohort, the subgroup of obese children/adolescents as compared to the adult cohort in this article.Among all the subscales tested, obese girls primarily showed significantly higher values of (preclinical) eating disorders than boys. These data are relevant for both prevention and health promotion.No significant differences were found in regard to sports motivation. This warrants facilitation of physical activity for both genders. Further, a male predilection for "Snacks" and "High-fat food" that could be found in the total representative study group, could not be verified in the subgroup of obese girls and boys, thus suggesting a similarily unhealthy eating behavior in both genders of juvenility.

Total antioxidant capacity and oxidative stress after a 10-week dietary intervention program in obese children. Eur J Pediatr 2014; 173:609-16. [PMID: 24310523 DOI: 10.1007/s00431-013-2229-7] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/23/2013] [Revised: 11/15/2013] [Accepted: 11/26/2013] [Indexed: 12/25/2022]
Abstract
UNLABELLED Dietary and serum total antioxidant capacity (TAC) are considered appropriate tools for investigating the potential health effects of dietary antioxidants consumed in mixed diets. The aim was to analyze the impact of a dietary intervention on macronutrient intakes and to evaluate the improvement on oxidative status after weight loss (WL) by measuring dietary and serum TAC, and urinary F2-isoprostane levels as markers of oxidative stress. Forty-four overweight/obese children (mean age 11.5 years) were enrolled to undergo a 10-week WL program. They were dichotomized at the median of body mass index-standard deviation score (BMI-SDS) change, as high (HR) and low responders (LR) after intervention. Subjects were prescribed with a fixed full-day meal diet, calculated according to their basal metabolic rate and physical activity levels. A validated food-frequency questionnaire was used to retrospectively calculate TAC and daily nutrient intake. The HR subjects were able to reduce anthropometric indices and to improve lipid and glucose profile. They also significantly diminished fat intake (p = 0.013). Moreover, baseline serum TAC values did significantly predict the reduction in urinary F2 isoprostane (B = -0.236 (-0.393 to -0.078); p = 0.014) in the HR group after the WL program. Notably, changes in dietary TAC after the treatment were associated with a decrease in body weight after the 10-week intervention (B = -2.815 (-5.313 to -0.318), p = 0.029) in the HR group. The -ΔSerumTAC/ΔDietaryTAC and the -ΔF2Isoprostane/ΔDietaryTAC ratios revealed that the relationships between oxidative markers and antioxidants dietary intake were more favorable in the HR than in the LR group. CONCLUSION Our study showed that a 10-week WL program was able to reduce adiposity indices in obese children. Moreover, after the intervention changes in dietary TAC and WL were significantly associated. Our result suggests that specific food with a high TAC content (such as fruits, vegetables, and legumes) could be recommended to improve WL.

Changes in the serum metabolite profile in obese children with weight loss. Eur J Nutr 2014; 54:173-81.

Abstract
PURPOSE Childhood obesity is an increasing problem and is accompanied by metabolic disturbances. Recently, we have identified 14 serum metabolites by a metabolomics approach (FIA-MS/MS), which showed altered concentrations in obese children as compared to normal-weight children. Obese children demonstrated higher concentrations of two acylcarnitines and lower levels of three amino acids, six acyl-alkyl phosphatidylcholines, and three lysophosphatidylcholines. The aim of this study was to analyze whether these alterations normalize in weight loss. METHODS We analyzed the changes of these 14 metabolites by the same metabolic kit as in our previous study in serum samples of 80 obese children with substantial weight loss (BMI-SDS reduction >0.5) and in 80 obese children with stable weight status all participating in a 1-year lifestyle intervention. RESULTS In the children without weight change, no significant changes of metabolite concentrations could be observed. In children with substantial weight loss, glutamine, methionine, the lysophosphatidylcholines LPCaC18:1, LPCaC18:2, and LPCa20:4, as well as the acyl-alkyl phosphatidylcholine PCaeC36:2 increased significantly, while the acylcarnitines C12:1 and C16:1, proline, PCaeC34:1, PCaeC34:2, PCaeC34:3, PCaeC36:3, and PCaeC38:2 did not change significantly. CONCLUSIONS The changes of glutamine, methionine, LPCaC18:1, LPCaC18:2, LPCa20:4, and PCaeC36:2 seem to be related to the changes of dieting or exercise habits in lifestyle intervention or to be a consequence of overweight since they normalized in weight loss. Further studies should substantiate our findings.

Abstract
OBJECTIVE To test whether weight and the weight gain rate during different age periods are associated with being overweight/obese at 10 years of age. METHODS A nested case-control study was performed in a clinical historic cohort that was selected based on medical records from the Albert Einstein Hospital Social Program in São Paulo, Brazil. A sample of 378 eutrophic and overweight/obese children was analyzed. RESULTS After adjusting for birth weight and gestational age, the likelihood of being overweight/obese at 10 years of age was 4.04-fold greater when progressing from one quartile of weight gain to the immediately superior quartile in the first semester of life and 3.24-fold greater when this occurred from 2-5 years of age. A one-quartile change in weight gain in the first semester was associated with a 0.5 z-score increase in BMI at age 10. A robust independent effect of weight at age 5 confirmed that earlier weight gain was an important predictor. CONCLUSIONS The amount of weight gain during the first 6 months of life and between 2 and 5 years of age and weight at age 5 were important predictors of overweight/obesity at 10 years of age.

Abstract
BACKGROUND Obesity is increasing in Bahrain and there is lack of information on the energy and macronutrient intake of children. The objective of this research was to study the energy and macronutrient intake as well as food frequency pattern of Bahraini school children. METHODS This is a cross-sectional descriptive study conducted on Bahraini school boys and girls aged 6-18 years from all the 11 populated regions of the country. Data on food intake consisted of a 24-hour dietary recall and was obtained by interviewing a sub-sample of the study population. Information was also obtained through a self-administered questionnaire for the entire sample on the weekly frequency of food items that were grouped into 7 categories based on similarity of nutrient profiles. Dietary analysis was performed using the Nutritionist 5 (First Data Bank Version 1.6 1998). RESULTS While the average energy intake of students was close to the Estimated Average Requirements of the UK Reference standards, protein intake substantially exceeded the Reference Nutrient Intake values as did daily sugar consumption. Dietary fiber fell short of the Dietary Recommended Values (UK) and 36%-50% students exceeded the Energy % limits for total fat, saturated fat and cholesterol. The Polyunsaturated: Saturated fat ratio remained at an unacceptable level of 0.6 for girls and boys. While sweets, snacks and regular soda drinks were popular, milk, fruits and vegetables were not commonly consumed. CONCLUSIONS High sugar consumption, low intake of dietary fiber and high energy % of saturated fat and dietary cholesterol by many Bahraini children, is likely to increase their risk of obesity and cardiovascular diseases in later life. Nutrition education programs in schools should emphasize the importance of healthy balanced diets for growth and health maintenance of children as well as dietary prevention of diseases.

Abstract
OBJECTIVES The aim of this study was to describe developed methods for repeated longitudinal assessment of feeding habits and nutrient intakes of children in a multicenter trial in different European countries and to assess feasibility. PATIENTS AND METHODS Nutrient intake and dietary habits of formula-fed and breast-fed infants were assessed in 5 European countries (Belgium, Germany, Italy, Poland, and Spain). Prospective age-adapted 3-day weighed food records were used from birth to 2 years of age (1, 2, 3, 4, 5, 6, 7, 8, 9, 12, 18, and 24 months). Standard operating procedures were developed to check each day's food record for quality. Dietitians were trained by using standardized food records. Data entry and nutrient analyses were performed with a dedicated software developed for this project. RESULTS Of 1368 study participants, at least one 3-day food record was available; of 25,367 1-day food records, data on quality could be evaluated. Overall, between 81% and 97% (depending on the country) of the food records had been completed with high accuracy. The implementation of solid foods and regular family foods decreased the recording quality significantly during the 2-year time course (P < 0.001). The standardized training shows coefficients of variation up to a maximum of about 41%, indicating differences in data entry. CONCLUSIONS The experiences gathered indicate that collecting dietary and behavioral data in a large number of infants from different cultures is a challenging but feasible task in which permanent supervision and training is vital. However, we conclude that the established methodology is suitable to obtain valuable results on current infant nutrition practice in Europe.

Dietary intakes and food sources of fat and fatty acids in Guatemalan schoolchildren: a cross-sectional study. Nutr J 2010; 9:20.

Abstract
BACKGROUND Consumption of healthy diets that contribute with adequate amounts of fat and fatty acids is needed for children. Among Guatemalan children, there is little information about fat intakes. Therefore, the present study sought to assess intakes of dietary fats and examine food sources of those fats in Guatemalan children. METHODS The study subjects consisted of a convenience sample of 449 third- and fourth-grade schoolchildren (8-10 y), attending public or private schools in Quetzaltenango City, Guatemala. Dietary data was obtained by means of a single pictorial 24-h record. RESULTS The percentages of total energy (%E) from total fat, saturated fat (SFA) and monounsaturated fat (MUFA) reached 29%E for total fat and 10%E for each SFA and MUFA, without gender differences. %E from fats in high vs. low-socio economic status (SES) children were significantly higher for boys, but not for girls, for total fat (p = 0.002) and SFA (p < 0.001). Large proportions of the children had low levels of intakes of some fatty acids (FA), particularly for n-3 FA, with >97% of all groups consuming less than 1%E from this fats. Fried eggs, sweet rolls, whole milk and cheese were main sources of total fat and, SFA. Whole milk and sweet bread were important sources of n-3 FA for high- and low-SES boys and girls, respectively. Fried plantain was the main source of n-3 FA for girls in the high-SES group. Fried fish, seafood soup, and shrimp, consumed only by boys in low amounts, were sources of eicosapentaenoic (EPA) and docosahexaenoic (DHA) acids, which may explain the low intakes of these nutrients. CONCLUSIONS alpha-linolenic acid, EPA and DHA were the most limiting fatty acids in diets of Guatemalan schoolchildren, which could be partially explained by the low consumption of sources of these nutrients, particularly fish and seafood (for EPA and DHA). This population will benefit from a higher consumption of culturally acceptable foods that are rich in these limiting nutrients.

Abstract
OBJECTIVES Little is known about the practice of introducing complementary feeding across Europe. We aim at describing times of solid introduction in healthy infants in 5 European countries. MATERIALS AND METHODS Between October 2002 and June 2004, 1678 healthy term infants were either breast-fed (BF) for at least 4 months (n = 588) or study formula-fed (FF) (n = 1090) with different protein contents. Three-day-weighed food protocols were obtained at ages 1, 2, 3, 4, 5, 6, 7, 8, 9, and 12 completed months. RESULTS Solids were introduced earlier in FF infants (median 19 weeks, interquartile range 17-21) than BF infants (median 21 weeks, interquartile range 19-24). Some 37.2% of FF infants and 17.2% of BF infants received solid foods at 4 completed months, which is earlier than recommended in Europe. Solids had been introduced at 7 completed months in 99.3% of FF infants and 97.7% of BF infants, respectively. Belgium had the highest percentage of solids feeding in FF infants at 3 (15.8%) and 4 (55.6%) completed months, and in BF infants at 4 (43%) and 5 (84.8%) completed months. Multiple regression showed low maternal age, low education level, and maternal smoking to predictors an early introduction of solids at 3 and 4 completed months. CONCLUSIONS Complementary feeding is introduced earlier than recommended in a sizeable number of infants, particularly among FF infants. Country- and population-specific approaches to adequately inform parents should be explored.

Abstract
OBJECTIVES To investigate infant feeding and breast-feeding practices during the first 9 months of life in Bavaria, Germany, in relation to recommendations and to identify factors associated with early feeding of semisolid food. MATERIALS AND METHODS Data from 3103 infants throughout Bavaria, Germany, were collected in a prospective cohort study. Questionnaires were administered at the age of 6 days, and 2, 4, 6, and 9 months. RESULTS There was a considerable variety concerning the time when complementary feeding was introduced. Only 16.4% of the infants ate solid/semisolid food before the age of 5 months. Most of the infants received as their first solid food a mash of vegetable, meat, and potato. Compared to national guidelines fluids were introduced early. More than 37% of the breast-fed infants received additional fluids/formula. The strongest risk factor associated with complementary feeding before the fifth month was breast-feeding duration of less than 4 months (any breast-feeding) with an odds ratio of 8.57 (95% confidence interval 6.16-11.94). Other factors were low level of education, young age of the mother, smoking habit of the mother, and mother not being born in Germany. CONCLUSIONS Further improvements in nutrition of infants may be achieved in 2 ways: promotion of breast-feeding according to current recommendations and better counselling on the correct timing of introduction of semisolid food-especially for parents of not- or short-time breast-fed babies and focused on young mothers with low levels of education.

Abstract
This position paper on complementary feeding summarizes evidence for health effects of complementary foods. It focuses on healthy infants in Europe. After reviewing current knowledge and practices, we have formulated these conclusions: Exclusive or full breast-feeding for about 6 months is a desirable goal. Complementary feeding (ie, solid foods and liquids other than breast milk or infant formula and follow-on formula) should not be introduced before 17 weeks and not later than 26 weeks. There is no convincing scientific evidence that avoidance or delayed introduction of potentially allergenic foods, such as fish and eggs, reduces allergies, either in infants considered at increased risk for the development of allergy or in those not considered to be at increased risk. During the complementary feeding period, >90% of the iron requirements of a breast-fed infant must be met by complementary foods, which should provide sufficient bioavailable iron. Cow's milk is a poor source of iron and should not be used as the main drink before 12 months, although small volumes may be added to complementary foods. It is prudent to avoid both early (<4 months) and late (>or=7 months) introduction of gluten, and to introduce gluten gradually while the infant is still breast-fed, inasmuch as this may reduce the risk of celiac disease, type 1 diabetes mellitus, and wheat allergy. Infants and young children receiving a vegetarian diet should receive a sufficient amount ( approximately 500 mL) of breast milk or formula and dairy products. Infants and young children should not be fed a vegan diet.

Abstract
The body mass index (BMI) is widely used as an indicator of nutritional status of individuals and groups, changes in this measure reflecting changes in living conditions. The purpose of this paper is to present long-term BMI trends of schoolchildren from Jena/Eastern Germany over 125 years. The analysis is based on 10 anthropological investigations carried out between 1880 and 2005/2006 and belongs to the longest running, continuous investigation of schoolchildren in a single community worldwide. The average BMI of the 7- to 14-year-old probands generally increases between the first investigation in 1880 and the last study in 2005/2006 by 1.8 kg/m(2) in boys and by 2.1 kg/m(2) in girls. However, this long-term increase of the BMI does not occur continuously. The trend was interrupted for example by declining average BMI values between 1932 and 1944. In contrast, the time after German reunification is characterised by a marked increase in this measure. The changes in BMI of Jena schoolchildren are also analysed in relation to energy intake in different years. There is an association between changes in energy intake and changes in BMI, which weakens after 1985. This indicates that the recent dramatic increase in the prevalence of overweight and obesity is not only due to an increased energy intake but also reflects a more inactive lifestyle of children and adolescents. The continuing change in the BMI pattern of Jena children and adolescents is discussed in regard to programmes of prevention of overweight and obesity.

Abstract
An adaptable model is presented for assessing the blood lipid concentrations of polychlorodibenzodioxins and polychlorodibenzofurans (PCDD/Fs) from dietary (breast milk, formula, milk, and other foods) and soil pathway exposures (soil ingestion and dermal contact) utilizing age-specific exposure and intake estimates for young children. The approach includes a simple one-compartment (adipose volume) toxicokinetic model that incorporates empirical data on age-dependent half-lives and bioavailability of PCDD/F congeners, child body size and intake rates, and recent data on breast milk and food dioxin levels. Users can enter site-specific soil concentration data on 2,3,7,8-chlorinated PCDD/F congeners for specific assessment of body burden changes from soil pathways in combination with background dietary exposures from birth through age 7 years. The model produces a profile of the estimated PCDD/F concentration in blood lipid (in World Health Organization 1998 dioxin toxic equivalents) versus time for a child from birth through age 7 years. The peak and time-weighted average (TWA) internal dose (defined as blood lipid dioxin toxic equivalents) for a variety of specific child exposure assumptions can then be compared to safe internal dose benchmarks for risk assessment purposes, similar to an approach taken by United States Environmental Protection Agency for assessing child lead exposures. We conclude that this adaptable toxicokinetic model can provide a more comprehensive assessment of potential health risks of PCDD/Fs to children because it integrates recent empirical findings on PCDD/F kinetics in humans and allows users to assess contributions from varied dietary and site-specific environmental exposure assumptions.

Abstract
OBJECTIVE To assess prospectively the consumption of fruit and vegetables and its' correlation to the parental consumption in boys and girls taking part in an atherosclerosis prevention study (Special Turku Coronary Risk Factor Intervention Project for Children (STRIP) study). HYPOTHESIS Nutrition counselling focused on cardiovascular health effects vegetable and fruit consumption. DESIGN A prospective, randomised, clinical trial. SUBJECTS Children were recruited to the STRIP study between 1989 and 1992. At the age of 7 months, children were randomised to the intervention (n = 540) or the control group (n = 522) and were followed up until the age of 11 years. INTERVENTION Families in the intervention group have, since randomisation, received biannual individualised dietary counselling aimed at reduction of cardiovascular risk factors, especially saturated fat intake. Food records were used to assess fruit and vegetable consumption of children and parents. RESULTS The percentage of total energy intake provided by fruit and vegetables decreased when the children grew older (P for age <0.001). The 1- to 10-year-old intervention boys consumed more vegetables (mean difference 3.18 g/day; CI 1.48-4.86; P < 0.001) and fruit (mean difference 10.1 g/day; CI 5.28-14.94; P < 0.001) than did the control. Mother's consumption correlated with the consumption of their daughters and sons, whereas father's consumption correlated only with the consumption of their sons. CONCLUSIONS Finnish children taking part in the atherosclerosis prevention study had a remarkably low fruit and vegetable consumption, which furthermore decreased with age. The children's consumption correlated with the parental consumption, except between boys and mothers. A slight intervention effect was present only among boys.
