Circulating Irisin in Healthy, Young Individuals: Day-Night Rhythm, Effects of Food Intake and Exercise, and Associations With Gender, Physical Activity, Diet, and Body Composition

To examine the hypothesis that physiologic regulation of short-term food intake (FI) in boys is affected by the interaction between physiological and environmental factors, four studies were conducted. The primary objectives were as follows: (i) to compare the effect of glucose and whey-protein (50 g) preloads on satiety and FI as affected by time to the next meal and body composition in normal weight (NW) and obese (OB) boys; (ii) to examine the role of short-duration physical activity on subjective appetite and to identify the role of and associations between fitness and FI at a pizza lunch 30 min after glucose and whey-protein drinks in NW boys; (iii) to determine the effect of television viewing (TVV) on FI of boys at a meal and its effect on caloric compensation at the test meal after a premeal glucose drink; and (iv) to determine the reproducibility of short-term FI and subjective appetite after a glucose preload, ventilation threshold (VT), and body composition assessed by bioelectrical impedance analysis (BIA). Obese boys responded less than NW boys to whey protein, with time (30 vs. 60 min) to the next meal the response decreasing to glucose but increasing to protein. Subjective appetite was increased by short-duration physical activity and FI following glucose and whey-protein preloads was positively associated with VT in boys. TVV while eating a meal contributed to increased energy intake by delaying normal mealtime satiation and reducing satiety signals from previously consumed foods. Short-term FI after a glucose preload, subjective appetite after glucose and physical activity, VT, and body composition assessed by BIA were reproducible in boys. In conclusion, physiologic regulation of short-term FI in boys was affected by the interaction between physiological and environmental factors. Macronutrient source, body weight and composition, time to the next meal, short-duration physical activity and fitness, and TVV at mealtime impacted on FI regulation in boys.

Inborn Errors

Children with inborn errors of intermediary metabolism (IEiM) must follow special diets that restrict their intake of essential nutrients and may compromise normal growth and development. We evaluated body composition, bone mineral density, physical activity, and food intake in IEiM patients undergoing dietary treatment. IEiM patients (n = 99) aged 5–19 years and healthy age- and sex-matched controls (n = 98) were recruited and underwent dual-energy X-ray absorptiometry to evaluate anthropometric characteristics and body composition. Data on food intake and physical activity were also collected using validated questionnaires. The height z-score was significantly lower in IEiM patients than controls (−0.28 vs. 0.15; p = 0.008), particularly in those with carbohydrate and amino acid metabolism disorders. Significant differences in adiposity were observed between patients and controls for the waist circumference z-score (−0.08 vs. −0.58; p = 0.005), but not the body mass index z-score (0.56 vs. 0.42; p = 0.279). IEiM patients had a significantly lower total bone mineral density (BMD) than controls (0.89 vs. 1.6; p = 0.001) and a higher risk of osteopenia (z-score < −2, 33.3% vs. 20.4%) and osteoporosis (z-score < −2.5, 7.1% vs. 0%), but none presented fractures. There was a significant positive correlation between natural protein intake and BMD. Our results indicate that patients with IEiM undergoing dietary treatment, especially those with amino acid and carbohydrate metabolism disorders, present alterations in body composition, including a reduced height, a tendency towards overweight and obesity, and a reduced BMD.

Bone Status

Achieving a high bone mass during childhood and adolescence is important for the prevention of osteoporosis in later life. Herein, the purpose was to assess the relationship of various lifestyle factors and bone outcomes in school children. In 248 girls (13.4 ± 1.9 years, BMI: 20.2 ± 4.8 kg m−2) and 231 boys (13.6 ± 1.7 years, BMI: 19.3 ± 3.3 kg m−2), bone mass (stiffness index, SI; calcaneal quantitative ultrasonometry), body composition (bioelectrical impedance analysis), food intake (food frequency questionnaire), and physical activity level (PAL; standardized questionnaire) were assessed. The individual food intake of eight food groups was related to the German recommendations (Bone Healthy Eating Index, BoneHEI; 0–100 points). Relationships between SI and lifestyle factors (Spearman´s rank correlation) and the influence of the factors on the variance of SI (multiple linear regression) were tested (α = 0.05). SI correlated with age, BMI, absolute fat-free mass, relative fat mass, PAL, and puberty category score in both girls and boys (r = 0.18–0.56, p < 0.01), but not with BoneHEI (p > 0.05). Age, absolute fat-free mass, sex, and PAL explained 35% of the variance of SI (p < 0.0001): SI = −0.60 + 2.97∙age (years) + 0.65∙fat-free mass (kg) + 6.21∙sex (0 = male, 1 = female) + 17.55∙PAL. Besides age and sex, PAL and fat-free mass are important factors relating to bone health. School children should perform regular physical activity to improve their bone status.

Global Physical Activity Questionnaire

Abstract Previous studies consistently showed a key role for omega-3 fatty acids in decreasing fat mass (FM) in animal models. Also, increased omega-3 stimulates fat loss in individuals who experience obesity, diabetes and metabolic syndrome. However, it is not known whether omega-3 supplementation make similar effects in healthy individuals with low FM. This study aimed to investigate the effects of omega-3 on changes in body composition, food intake, and lipid proﬁle in healthy athletes. In this double-blind placebo-controlled RCT, 36 healthy athletes were allocated into omega-3 or placebo groups. Physical activity (global physical activity questionnaire), dietary intake (24-h food recall), anthropometric status, and lipid proﬁle were measured at baseline and after 3-weeks. 35 volunteers completed the trial. The weight did not signiﬁcantly change at the end of the study. Body fat% decreased signiﬁcantly at the end of the study in the omega-3 group (p=0.003), but intergroup differences were not signiﬁcant (p=0.77). FM decreased and fat free mass (FFM) increased in omega-3 groups (p<0.05). HDL-C increased (omega-3 group p=0.001; placebo group p=0.01; after adjustment for baseline values p=0.78). Also, in the omega-3 group, energy intake (p=0.0007) and protein intake (p=0.04) increased after intervention, but after baseline adjustments they were not significant. In conclusion, 3-week omega-3 supplementation seems to be not effective in decreased FM, increased HDL-C, and energy and protein intakes in athletes. Further studies are recommended to determine the effect of different doses of omega-3 on adipose tissue and blood lipids in athletes with low FM. Clinical Trial Registration The present study was prospectively registered at the Iranian Registry of Clinical Studies on December 19, 2019 (ID: 20190625044008N1).

The Relationship

Most of the mothers are very attentitve to changes in body composition, especially postpartum weight loss. One of the factors believed to facilitate the weight loss and body fat loss in postpartum mothers is breastfeeding. Factor that affect the relationship between breastfeeding with maternal postpartum body composition are food intake and physical activity. The aim of this study is to analyze the change in body composition between the mother who give exclusive breastfeeding for 6 months and the mother who don’t and also attempts to analyze the effect of breastfeeding duration to the change in body composition and the factor affecting it.This study used the panel study with longitudinal approach. 32 respondents observed for 6 months. Fat mass measurement data are collected using skinfold caliper and breastfeeding status, food intake and physical actiuvity data are collected using interview. The relationship between breastfeeding with the change in body composition is analyzed using t-test analysis. T-test analysis are also used to test the effect of food intake and physical activity to breastfeeding. Regression analysis are used to analyze the effect of food intake and physical activity to body composition.According to the result of statistical analysis, there is no significance effect of breastfeeding for 6 months to the change in maternal postpartum body composition (fat mass and free fat mass) (p = 0.743; p = 0.771) and also no significance effect of food intake and physical activity to the relation between breastfeeding with the change in body composition. There is a significance effect of breastfeeding for 4 months to the change in the body composition (p = 0.046). The average fat mass change in mother who give exclusive breastfeed is higher than the one who don’t.From 32 respondents in this study, only 4 mothers can successfully give exclusive breastfeed for 6 months. The average fat mass change in mother who give exclusive breastfeed is higher than the one who don’t. There is no significance effect of breastfeeding for 6 months to the change in maternal postpartum body composition (fat mass and free fat mass). There is a significance effect of breastfeeding for 4 months to the change in maternal postpartum body composition.Keywords: Breastfeeding, body composition, maternal postpartum
