Abstract Objectives To investigate whether breastfeeding duration during infancy was related to body composition in adolescence. Methods The analytic sample comprised 536 Mexico City adolescents enrolled in an ongoing cohort study. Breastfeeding duration was estimated based on mother's report of when she started and stopped breastfeeding, assessed during follow up visits at 1, 3, 6, and 12 months postpartum. Trained health professionals conducted the anthropometric assessment of weight, height, waist circumference, and triceps, suprailiac, and subscapular skinfold thicknesses. Bioelectrical impedance was used to derive the fat, muscle, lean and trunk fat masses and percentages. Sex-specific linear regression was performed with body composition measures as outcomes and breastfeeding duration in months as a continuous exposure, accounting for age, maternal education, maternal smoking during pregnancy, maternal parity, birth weight, and length, length of gestation, and adolescent maturation status. Results The median (IQR) age was 14.62 (3.90) years, and 51.49% were females. Mean (SD) Body Mass Index Z-score was 0.58 (1.19) for females and 0.42 (1.29) for males. Breastfeeding duration ranged from 0 to 34 months with a median duration of 6.50 (9.00) and 7.00 (8.00) months in females and males, respectively. In males, there was a statistically significant positive association between duration of breastfeeding and skeletal muscle and lean mass in crude models (β = 0.19 [95% CI 0.07, 0.30] and β = 0.29 [95% CI 0.11, 0.46], respectively. Nonetheless, these associations were attenuated and no longer statistically significant when age and other covariates were included in the linear model (for muscle mass β = 0.02 [95% CI - 0.06, 0.10]) and lean mass β = 0.03 [95% CI - 0.09, 0.15]). There were no associations between breastfeeding duration and other body composition outcomes either in crude or adjusted sex-specific models. Conclusions After accounting for potential confounders, there was no evidence of a relationship between breastfeeding duration and adolescent body composition. Age was a crucial confounder, as younger adolescents in the cohort had shorter breastfeeding duration and lower skeletal and lean mass. Funding Sources NIH/NIEHS and EPA.

AbstractCraniopharyngioma is a histologically benign brain malformation with a fundamental role in satiety modulation, causing obesity in up to 52% of patients.To evaluate cardiovascular risk factors, body composition, resting energy expenditure (REE), and energy intake in craniopharyngioma patients and to compare the data with those from children with multifactorial obesity.All obese children and adolescents who underwent craniopharyngioma resection and a control group of children with multifactorial obesity in follow-up between May 2012 and April 2013.Anthropometric measurements, bioelectrical impedance, indirect calorimetry, energy intake, homeostatic model assessment insulin resistance (HOMA-IR), and dyslipidemia were evaluated.Twenty-three patients with craniopharyngioma and 43 controls were included. Children with craniopharyngioma-related obesity had a lower fat-free mass percentage (62.4 vs. 67.5; p=0.01) and a higher fat mass percentage (37.5 vs. 32.5; p=0.01) compared to those with multifactorial obesity. A positive association was found between %REE and %fat-free mass in subjects with multifactorial obesity (68±1% in normal REE vs. 62.6±1% in low REE; p=0.04), but not in craniopharyngioma patients (62±2.7 in normal REE vs. 61.2±1.8% in low REE; p=0.8). No differences were found in metabolic involvement or energy intake.REE was lower in craniopharyngioma patients compared to children with multifactorial obesity regardless of the amount of fat-free mass, suggesting that other factors may be responsible for the lower REE.

A Prospective Study

Abstract Objectives Maternal diet during pregnancy has been associated with offspring adipokine levels related to insulin resistance and hyperlipidemia during infancy. However, whether this relationship persists into adolescence is unknown. We examined the association between maternal prenatal diet patterns with adolescent leptin and adiponectin levels a Mexico City cohort. Methods Data from 379 mother-adolescent dyads from the Mexico City ELEMENT cohort were analyzed. Diet patterns were derived from principal component analysis of food frequency questionnaire data collected during pregnancy trimesters. Adolescent serum leptin and adiponectin were measured at ages 10–17. Information on maternal covariates was measured during pregnancy. Multiple linear regression was used to examine overall and sex-stratified associations between quartiles of diet patterns with leptin and adiponectin, adjusting for maternal marital status, education, and parity. Results Three maternal diet patterns were identified: Prudent Diet (PD), high in fish and vegetables, the High Meat & Fat Diet (HMFD), high in pork and processed meats, and the Transitioning Diet (TD), high in corn tortillas and sugar beverages. At follow-up, the mean (SD) of leptin and adiponectin were 24.3 (18.2) ng/ml and 11.7 (3.9) ng/ml. A significant positive association was demonstrated between first trimester TD scores and adipokines in girls. In a multivariate-adjusted model, compared to girls in the lowest quartile (Q1) of the TD pattern, the highest quartile of the TD pattern (Q4) had 10.39 ng/mL higher leptin (95% CI: 3.1, 17.6; p for trend = 0.0024). In addition, compared to girls in the lowest quartile (Q1) of the TD pattern, those in the third quartile (Q3) of the TD pattern had 1.86 ng/mL lower adiponectin (95% CI: −3.5, −0.2; p for trend = 0.168). Associations were mostly consistent across all trimesters. Conclusions During pregnancy, a Transitioning Diet pattern was positively associated with leptin and non-monotonically inversely associated with adiponectin in females. Findings suggest maternal diet patterns during pregnancy may influence offspring leptin and adiponectin levels in adolescent girls. Funding Sources Funded by grant P01ES022844.

The present study aimed to check if there is an association between fitness performance variables and to analyze the variation of fitness levels between playing positions university soccer players. Twenty university soccer players were selected (20.95 ± 1.84 years; 71.60 ± 11.65 kg; 176.85 ± 7.28 m) divided into defenders, midfielders and attackers. Body composition was assessed in a cross-sectional analysis that correlated fat mass, lean mass and fat-free mass by DXA with the physical capacity tests. The main results of the present study revealed that both 10-m and 20-m accelerations had moderate-to-large correlations with agility tests across the playing positions, however these accelerations were largely inversely correlated with YoYo intermittent recovery test in defenders and largely positively in midfielders. The agility test was moderately correlated with YoYo intermittent recovery test across the different playing positions. In conclusion, there the acceleration and the agility had a positive association with the different positions of the soccer players.

Abstract Objective: To identify factors associated with breastfeeding initiation and continuation in Canadian-born and non-Canadian-born women. Design: Prospective cohort of mothers and infants born from 2008–2012: the CHILD Cohort Study. Setting: General community setting in four Canadian provinces. Participants: 3455 pregnant women from Vancouver, Edmonton, Winnipeg, and Toronto between 2008 and 2012. Results: Of 3010 participants included in this study, the majority were Canadian-born (75.5%). Breastfeeding initiation rates were high in both non-Canadian-born (95.5%) and Canadian-born participants (92.7%). The median breastfeeding duration was 10 months in Canadian-born participants and 11 months in non-Canadian-born participants. Among Canadian-born participants, factors associated with breastfeeding initiation and continuation were older maternal age, higher maternal education, living with their partner, and recruitment site. Rooming-in during the hospital stay was also associated with higher rates of breastfeeding initiation, but not continuation at 6-months postpartum. Factors associated with non-initiation of breastfeeding and cessation at 6-months postpartum were maternal smoking, living with a current smoker, cesarean birth, and early-term birth. Among non-Canadian-born participants, maternal smoking during pregnancy was associated with lower odds of breastfeeding initiation, and lower odds of breastfeeding continuation at 6 months, and older maternal age and recruitment site were associated with breastfeeding continuation at 6 months. Conclusions: Although Canadian-born and non-Canadian-born women in the CHILD cohort have similar breastfeeding initiation rates, breastfeeding initiation and continuation are more strongly associated with sociodemographic characteristics in Canadian-born participants. Recruitment site was strongly associated with breastfeeding continuation in both groups and may indicate geographic disparities in breastfeeding rates nationally.

Aim: To evaluate a two-year longitudinal development of health-related fitness, anthropometry and body composition status amongst adolescents in Tlokwe Municipality, Potchefstroom, South Africa.Setting: A total of 283 high-school learners (111 boys and 172 girls) of ages 14 and 15 years who were part of the ongoing Physical Activity and Health Longitudinal Study (PAHLS) participated in the study. For the purpose of the present study, data collected for 2011 and 2012 for anthropometric, body composition and health-related physical fitness were used.Results: Body mass index (BMI) classification of boys and girls for 2011 and 2012 showed that 24.3% of them were underweight compared with 21% in 2012. In 2011, 50% of boys and girls had normal bodyweight compared with 52% in 2012, whilst 25.5% of the total group of participants were overweight compared with 27% in 2012. Both boys and girls showed significant increases of 5.9% in body fat (BF) and 3.2 kg in body weight over two years’ measurements, respectively. Regarding health-related fitness (i.e BAH), boys showed an increase of 14.8 seconds whilst girls gained 9.6 seconds. Significant decreases were found for sit-ups in both boys and girls. A significant VO2max increase of 2.9 mL/kg/min. was found in boys over the time period. A non-significant decrease of -0.5 mL/kg/min. was observed in girls. Regression coefficients showed that changes in BMI were inversely associated with those in health-related physical fitness. The changes in percentage BF were negatively associated with standing broad jump (SBJ), bent arm hang (BAH) and VO2 max in both boys and girls. A low significant positive association was found between changes in waist-to-height ratio (WHtR) and SBJ in both genders, whilst inverse low associations were found between WHtR and BAH in girls and for VO2max in both genders.Conclusion: Changes in BMI, %BF and WHtR were negatively associated with strength and running performances in the participating children. The relative increase in overweight, especially in girls, negatively affected their endurance running and static strength performances. The health implications of the observed findings are discussed and recommendations offered for physical activity intervention in school physical education (PE) programmes.

Paternal Obesity

Abstract Objectives Emerging evidence suggests that paternal obesity plays a significant role on offspring health. Our previous work in rodents showed that high fat diet (HFD) induced paternal obesity reduced offspring glucose tolerance. It has also been reported that paternal obesity can initiate metabolic disturbance in subsequent generations. Therefore, we designed a novel micronutrient supplement to ameliorate the transgenerational effects of paternal obesity. Methods Founder (F0) male Sprague Dawley rats (3 weeks, 12 per group) were weaned on control (CD) or HFD or diets containing micronutrient supplement (CS; HS), after which they were mated with CD fed females at 19 weeks of age. Twelve F1 offspring from each litter across the four diet groups were weaned on day 21 onto CD, generating four F1 groups. After 14 weeks on CD, they were mated with CD fed females. Male F2 siblings were fed CD or HFD from day 21. After 6 weeks on diet, they underwent EchoMRI (See attached study design). Results HFD increased adiposity (CD: 12.3%, HFD: 18.6%) in F0 which was normalized by supplementation (HS: 11.7%). Though no paternal effect on adiposity was found in F1 males across the four groups, supplementing F0 had significant impact on F2 body composition (fat mass, fat and lean percentage) without influencing body weight and lean mass after 6 weeks on diet. In F2, post weaning HFD significantly increased fat mass in rats from CD and HFD fed founders (CH vs CC P = 0.0001; HH vs HC P = 0.009) but this effect was significantly reduced by F0 supplementation irrespective of F0 diets (CSH vs CH P = 0.017; and HSH vs HH P = 0.04) [3-way ANOVA][See attached table]. Moreover, lean percentage was decreased by post weaning HFD in rats from both non-supplemented F0 diet groups but interestingly this effect was significantly reduced only in rats sired by supplemented CD fed F0 (CSH > CH; P = 0.04). Conclusions Supplementing CD fed grandfathers ameliorated the deleterious effect of HFD, decreasing fat deposition and increasing lean percentage whereas supplementing HFD fed F0 reduced only fat deposition without affecting lean mass of male grand offspring. Therefore, our designed supplement could eventually reduce the transgenerational effect of paternal obesity.

White Matter Connectivity

Extended breastfeeding through infancy confers benefits on neurocognitive performance and intelligence tests, though few have examined the biological basis of these effects. To investigate correlations with breastfeeding, we examined the major white matter tracts in 4–8 year-old children using diffusion tensor imaging and volumetric measurements of the corpus callosum. We found a significant correlation between the duration of infant breastfeeding and fractional anisotropy scores in left-lateralized white matter tracts, including the left superior longitudinal fasciculus and left angular bundle, which is indicative of greater intrahemispheric connectivity. However, in contrast to expectations from earlier studies, no correlations were observed with corpus callosum size, and thus no correlations were observed when using such measures of global interhemispheric white matter connectivity development. These findings suggest a complex but significant positive association between breastfeeding duration and white matter connectivity, including in pathways known to be functionally relevant for reading and language development.

Abstract Background/Aims  Body composition changes are associated with changes in bone mineral density (BMD). Composite measures of body compartments, such as weight and body mass index (BMI) have a positive association with BMD. The aim was to study average percent fat from dual energy X-ray absorptiometry (DEXA) as a potentially useful clinical measurement. Methods  BMD data in grams/cenitmetre2 was collected from DEXA scans after referral from secondary care to the Royal Lancaster Infirmary from 2004-2010. BMD data related to the left and right hip (the neck, Ward’s area, trochanter, and total hip), and the spine (L1-L4) was measured. Data was collected longitudinally, and BMD in g/cm2 was modelled at the regions of the hip and spine using mixed effects linear models. Average percent fat and weight (kg) were used as explanatory variables, whilst adjusting for age at scan, gender, and other risk factors such as FRAX risk factors. Results  7910 patients (88% female) were included, all with average percent fat and weight measurements. The results of the models (Table 1) all have a P value<0.05. Average percent fat had a significant negative association at all regions of the left and right hip, but a significant positive association at the spine. Weight showed a significant positive association with BMD at the hip and spine.

Increased adiposity is also linked to sarcopenia, and further body compositional changes. However, the potential negative effects of increased adiposity at the abdomen and spine are potentially overridden by the increased biomechanical loading generated by the increased adiposity, highlighted by weight’s positive association with BMD at the spine. The average percent fat results are not mirrored with weight at the hip. This highlights that composite measures are not specific enough to measure changes in body composition compartments, and their resulting change in risk related to BMD. Disclosure  C. Thurston: None.

Body composition (lean mass, fat content) was assessed in 32 women aged 21 to 78 by measuring the thickness of subcutaneous fat in 4 typical sites and urinary excretion of creatinine, and estimating whole-body bioelectrical impedance (BI) by tetrapolar analyzer attached to personal computer. Results of BI measurements better correlated with body composition values assessed from the thickness of subcutaneous fat (particularly so in subjects aged under 50 and with Broca’s index from 0 to +19%). Hence, BI assessment may be used to evaluate body composition in patients with various endocrine diseases before the treatment and to monitor its efficacy in some diseases.

Abstract Reduction of lean mass is a primary body composition change associated with aging. Because many factors contribute to lean mass reduction, the problem has been given various names depending on the proposed cause, such as “age-related sarcopenia,” “dynapenia,” “myopenia,” “sarcopenic obesity,” or simply “sarcopenia.” There is currently no consensus on how to best diagnose the reduction of lean mass and its consequences on health. We propose that simple body composition methods can be used to indirectly evaluate sarcopenia, provided that those techniques are validated against the “quality of lean” criterion that associates muscle mass and metabolic function with the components of fat-free mass. Promising field methods include the use of stable isotopes for the evaluation of water compartments and new approaches to bioelectrical impedance analysis, which is also associated with the monitoring of water homeostasis.
