Abstract Background To investigate the associations between adiposity and attained height over a 2-year period in healthy adolescents. Methods One thousand and seventeen adolescents aged 12–18 years participated in this cohort study; 893 (87.8%) were reevaluated 1 year later (T2) and 734 (72.2%) subjects 2 years later (T3). Body fat and anthropometry were measured according to standardized procedures. Socioeconomic status, pubertal stage and lifestyles determinants were gathered and used as confounders. Prospective associations between adiposity and height were examined using generalized linear models. Results Greater adiposity at T1 was significantly associated with a lower attained height over time, when adjusting for confounders, which varied between 0.03 and 1 cm in T2 and 0.1 and 1 cm in T3. Conclusions Excess of adiposity in early adolescence may exert an effect on attained height in late adolescence. This study supports future lifestyles intervention studies aiming at preventing overweight and obesity and improving attained height.

ObjectivesIn the present study, we examined the relation between socioeconomic status (SES) and the physiological distribution of iron-related blood parameters.DesignThis is a cross-sectional analysis of longitudinal population-based cohort study.SettingBased on a sample of healthy participants from a German research centre, various blood parameters and values of clinical examinations and questionnaires were collected.ParticipantsA total of 1206 healthy volunteers aged 2.5 to 19 years, one child per family randomly selected, were included.Primary and secondary outcome measuresAssociations between the SES of children by Winkler-Stolzenberg Index (WSI) and its dimensions (income, education, occupation) and iron-related blood parameters (haemoglobin, ferritin and transferrin) were analysed by linear regression analyses. Gender and pubertal stage were included as covariables. Additionally, associations between SES of children by WSI and physical activity (side-to-side jumps, push-ups) as well as body mass index (BMI) were analysed by linear regression analyses.ResultsChildren with high WSI or family income showed significantly increased z-scores for haemoglobin (P=0.046; P<0.001). Children with increased WSI or family income showed significantly lower z-scores for transferrin (P<0.001). There was a significant correlation between haemoglobin and gender (P<0.001) and between transferrin and pubertal stage (P=0.024). Furthermore, physical activity was positively correlated and BMI was negatively correlated with WSI (P<0.001).DiscussionOur data show an association between SES and the distribution of iron-dependent parameters. Lower SES is correlated with lower values for haemoglobin and higher values for transferrin. Furthermore, we demonstrate that physical activity and BMI are associated with SES. Whereas higher SES is correlated with higher values for physical activity and lower BMI. Our parameters are standardised as z-scores with the advantages that the results are comparable across different age groups and present physiological courses.Trial registration numberNCT02550236; Results.

ABSTRACTOBJECTIVES: To assess the eating habits and physical activity of adolescents enrolled in two public schools in the city of Ribeirão Preto (SP). METHODS: A case-control study was conducted to analyze the eating habits and practice of physical activity of a group of overweight adolescents and of a eutrophic control group matched for sex and age. The International Physical Activity Questionnaire (IPAQ short version) and a semi-quantitative food frequency questionnaire were applied and a 3-day food record was obtained. The nutritive value of the foods consumed was calculated with the Virtual Nutri® software. Body fat was estimated using the equations of Slaughter et al. Data were analyzed statistically by ANOVA and by the Fisher exact test. RESULTS: Fifty-one (44.7%) overweight and 63 (55.2%) eutrophic adolescents were studied. Mean BMI was 29.5 for the overweight group and 21.0 for the eutrophic group, and percent body fat was 49.4 and 29.1, respectively (p<0.01-ANOVA). The daily calorie intake of the eutrophic adolescents consisted of 56.7% carbohydrates, 15.4% proteins and 27.9% lipids and the intake of the overweight group was 52.7%, 17.1% and 30.2%, respectively. In the eutrophic group, 28.6% were considered to be very active and 60.3% active and in the overweight group these values were 23.5% and 70.6%, respectively.CONCLUSIONS: Information about the eating and physical activity habits of adolescents is of fundamental importance for subsidizing individual and community actions. Although adolescents report apparently adequate physical activity and calorie consumption, health professional should be aware of the high rates of overweight and obesity detected in this age range.

ObjectiveObesity tends to cluster in families reflecting both common genetics and shared lifestyle patterns within the family environment. The aim of this study was to examine whether parental lifestyle changes over time, exemplified by changes in weight and physical activity, could affect offspring weight in adolescents and if parental education level influenced the relationship.Design, setting and participantsThe population-based cohort study included 4424 parent-offspring participants from the Nord-Trøndelag Health Study, Norway. Exposition was parental change in weight and physical activity over 11 years, and outcome was offspring weight measured in z-scores of body mass index (BMI) in mixed linear models.ResultsMaternal weight reduction by 2–6 kg was significantly associated with lower offspring BMI z-scores: −0.132 (95% CI −0.259 to −0.004) in the model adjusted for education. Parental weight change displayed similar effect patterns on offspring weight regardless of parents’ education level. Further, BMI was consistently lower in families of high education compared with low education in the fully adjusted models. In mothers, reduced physical activity level over time was associated with higher BMI z-scores in offspring: 0.159 (95% CI 0.030 to 0.288). Associations between physical activity change and adolescent BMI was not moderated by parental education levels.ConclusionLifestyle changes in mothers were associated with offspring BMI; reduced weight with lower—and reduced physical activity with higher BMI. Father’s lifestyle changes, however, did not significantly affect adolescent offspring’s weight. Overall, patterns of association between parental changes and offspring’s BMI were independent of parental education levels, though adolescents with parents with high education had lower weight in general.

DOI: http://dx.doi.org/10.5007/1980-0037.2016v18n5p557 Excess body fat is associated with chronic degenerative diseases, being a global public health problem. The aim of this study was to investigate the association of obesity with sociodemographic factors, lifestyle (physical activity, dietary habits) and sexual maturation in high school students of a city in southern Brazil. This is a crosssectional study with 820 adolescents enrolled in public high schools of São José, Santa Catarina, Brazil, aged 14-17 years. Obesity was estimated by body fat percentage (BF%). BF% was calculated using the Lohman equation, which considers the sum of skinfolds (triceps and subscapularis). Cutoff points proposed by William et al. were used to classify individuals into normal weight or obese. Independent variables were sex, age, economic status, parental education, eating habits, physical activity and sexual maturation. The prevalence of obesity was 17.2%. Females (OR: 4.22; 95% CI: 2.72-6.54) and young people at post-pubertal stage of sexual maturation (OR: 1.95; 95% CI: 1.33-2.86) were more likely to have obesity. These results may help health authorities in the planning of public policies to prevent obesity.

AbstractBeing physically active is associated with fundamental health benefits and assists with the maintenance of normal weight in children. The current World Health Organizations’ recommendation is for children to accumulate 60 minutes of physical activity (PA) per day to obtain such benefits. Conversely, time spent in sedentary behaviours including watching screens (ST) are positively associated with the risk of overweight and obesity in young people. The aim of this research was to estimate PA levels and ST usage of Irish children and to examine the relationship with body fat.This analysis was based on data collected from a nationally representative sample of Irish children aged 5–12-years (n = 591, 50% female) from The National Children's Food Consumption Survey II (www.iuna.net). The Child/Youth Physical Activity Questionnaires (C-PAQ/Y-PAQ) were used to measure PA and ST in 5–8 and 9–12-year-olds respectively. Both questionnaires were self-administered, recall instruments that assessed the frequency/duration of activities participated in over the previous 7-day period. The MET minutes (metabolic cost of the activity multiplied by the duration in minutes) of the PA's were calculated per child. Percentage body fat (%BF) was measured by a Tanita BC420MA device and participants were classified into categories based on their %BF, age and gender. Independent t-tests and ANOVA (post-hoc DunnettT-3) were used to assess differences between gender and %BF category.Overall, children spent 93 mins/d being physically active with 69% meeting the > 1hr recommendation. There was a significant difference in the time spent undertaking PA between boys (99 mins/d) and girls (88 mins/d) p = 0.020. Children spent 107 mins/d watching screens with 68% meeting the < 2hr guidance. Girls spent significantly less time watching screens (89 mins/d) than boys (124 mins/d) p ≤ 0.001. Children who had a normal %BF accumulated more PA MET mins/day compared to those who were classified as obese, which was significant in the total population (p = 0.007), for boys (p ≤ 0.001), but not girls (p = 0.929).This preliminary analysis indicates that a high proportion of Irish children are meeting the PA and ST recommendations, with boys being more physically active and spending more time watching screens compared to girls. However, results should be interpreted with caution as PA and ST usage were self-reported by participants. The association between PA MET minutes and %BF suggest that advice to encourage PA participation to combat excess adiposity in Irish children is justified. Future work should examine the role of other potential determinants of obesity in this cohort.

Abstract Background The main objective of this study was to investigate the interaction effect of school socioeconomic composition (SEC) and adolescent socioeconomic status (SES) in the prevalence of overweight and obesity among a representative sample of French adolescents of the third most populous département of France. Methods 1038 adolescents agreed to participate (response rate: 91.4%). They self-reported anthropomorphic variables, SES, school lunch and physical activity. The body mass index was divided into six categories according to the Center for Disease Control. Multivariable binary logistic regressions analysis without and with interaction term were performed on overweight or obesity. Models fit was compared using the Aikaike Information Criterion. Odds-ratios (OR) and their 95% accelerated-bootstrap confidence interval (95%BCa CI) were computed to estimate overweight or obesity risk. Results 8.9% of the adolescents were overweight. 3.4% were obese. No school-SEC effect was observed among low-SES adolescents. Medium-SES adolescents were at greater risk in low-SEC (OR = 10.75, 95%BCa CI = 2.67–64.57) and medium-SEC (OR = 5.08, 95%BCa CI = 1.55–24.84) compared with high-SEC schools. High-SES adolescents in low-SEC schools were at greater risk compared with those in medium-SEC (OR = 5.94, 95%BCa CI = 1.94–17.29) and high-SEC schools (OR = 4.99, 95%BCa CI = 1.71–13.14). A social gradient was observed in medium-SEC (ORlow/high = 2.79, 95%BCa CI = 1.22–7.41) and high-SEC (ORlow/medium = 6.86, 95%BCa CI = 1.06–5.22*106) schools. Conclusions Physical activity and lunch at and outside school help to understand these differences. Implications for obesity prevention initiatives are discussed.

Abstract Background Adherence to a traditional Mediterranean diet has been associated with lower mortality and cardiovascular disease risk. The relative importance of diet compared to other lifestyle factors and effects of dietary patterns over time remains unknown. Methods We used the parametric G-formula to account for time-dependent confounding, in order to assess the relative importance of diet compared to other lifestyle factors and effects of dietary patterns over time. We included healthy Melbourne Collaborative Cohort Study participants attending a visit during 1995–1999. Questionnaires assessed diet and physical activity at each of three study waves. Deaths were identified by linkage to national registries. We estimated mortality risk over approximately 14 years (1995–2011). Results Of 22,213 participants, 2163 (9.7%) died during 13.6 years median follow-up. Sustained high physical activity and adherence to a Mediterranean-style diet resulted in an estimated reduction in all-cause mortality of 1.82 per 100 people (95% confidence interval (CI): 0.03, 3.6). The population attributable fraction was 13% (95% CI: 4, 23%) for sustained high physical activity, 7% (95% CI: − 3, 17%) for sustained adherence to a Mediterranean-style diet and 18% (95% CI: 0, 36%) for their combination. Conclusions A small reduction in mortality may be achieved by sustained elevated physical activity levels in healthy middle-aged adults, but there may be comparatively little gain from increasing adherence to a Mediterranean-style diet.

The purpose of this study was to develop a multivariate model with cross-sectional data that defined the decline in VO2max over time, and cross-validate the model with longitudinal data. The cross-sectional sample consisted of 1,608 healthy men who ranged in age from 25 to 70 years. VO2max was directly measured during a maximum Bruce treadmill stress test. Regression analysis showed that the cross-sectional age and VO2max relationship was linear, r = 0.45 and the age decline in VO2max was 0.48 ml/kg/min/year. Multiple regression developed the multivariate model from age, percent body fat (%fat), self-report physical activity (SR-PA), and the interaction of SR-PA and %fat (R = 0.793). Accounting for the variance in percent body fat and exercise habits decreased the influence of age on the decline of VO2max to just −0.27 ml/kg/min/year. This showed that much of decline in maximal physical working capacity was due to physical activity level and percent body fat, not aging. The multivariate equation was applied to the data of the longitudinal sample of 156 men who had been tested twice (Mean AgeΔ = 3.1 ± 1.2 years). The correlation between the measured and estimated change in VO2max over time (ΔVO2max) was 0.75. The results of the study showed that changes in body composition and exercise habits had more of an influence on changes in maximal physical working capacity than aging. The developed model provides a useful way to quantify the changes in physical working capacity with aging.
