Total body water by BIA in children and young adults with normal and excessive weight.

ABSTRACT:

Background

Estimation of total body water (TBW) is essential for clinical care.

Objective

Evaluation of changes in TBW by bioelectrical impedance analysis (BIA) in children and young adults with excessive weight.

Design

Data was collected in individuals aged 3-21 years with normal (n = 202) or excessive body weight (n = 133). The BIA results from individuals with normal weight were compared with two previously published studies in children by isotope dilution methods.

Results

Individuals with excessive weight had a higher mean TBW (27.87 L, SE 0.368) for height and age as compared to individuals with normal weight (23.95 L, SE 0.298), P<0.001. However, individuals with excessive weight had lower mean TBW (24.93 L, SE 0.37) for weight and body surface area (BSA) as compared to individuals with normal weight (26.94 L, SE 0.287), P<0.001. Comparison with two previously published studies showed no significant differences in mean TBW with one ((p = 1.00) but a significant difference with another study (p = 0.001).

Conclusions

Individuals with excessive weight had 16.5% higher mean TBW for height and age and 7.4% lower TBW for weight and BSA as compared to normal weight individuals. Our study validates the feasibility of data collection in pediatric outpatient setting by BIA.

Project description:BackgroundDuring the COVID-19 pandemic, physical inactivity and sedentary behaviors (i.e., longer sitting time and excessive gaming) increased because governments across the globe adopted stringent mitigation strategies such as social distancing and lockdowns to curb the spread of the virus. Excessive gaming was one of the coping mechanisms used to deal with the pressure associated with the pandemic. Moreover, perceived weight stigma (PWS) and weight status became more salient concerns among young adults during the COVID-19 pandemic. The current study sought to investigate the relationship between time spent sitting, excessive gaming, weight status, and PWS of Taiwanese Young adults. Additionally, weight status and PWS were examined as mediators between both sedentary behaviors.MethodsThis cross-sectional study involved 600 participants who were recruited through Taiwan universities. All participants completed a demographic questionnaire (including weight and height) and self-report measures including the International Physical Activity Questionnaire short form (IPAQ-SF), the Perceived Weight Stigma Scale (PWSS), and the Internet Gaming Disorder Scale-short form (IGDS9-SF). PROCESS model was performed to test the potential mediation roles of weight status and PWS. Moreover, we categorized participants into two groups based on the sitting-time item in the IPAQ-SF: students whose sitting time was less than 8 h daily, and those more than 8 h daily.ResultsThe group that had less than 8 h had significantly higher PWS and IGDS9-SF scores than the other group. Sitting time was negatively associated with weight status, PWS, and IGDS9-SF. Additionally, we found a significantly direct effect between time spent sitting and excessive gaming. Both weight status and PWS were significant mediators in the association between time spent sitting and excessive gaming.Conclusions: The present study demonstrated important negative correlates of excessive sedentary behaviors. Prevention efforts should focus on promoting physical activity and providing information to decrease sedentary behavior among university students.

Project description:BackgroundVery low birth weight (VLBW; <1500 g) infants have increased adiposity and metabolic disease risk in adulthood. Limited evidence suggests low-quality childhood diets are a predisposing risk factor. Despite this, to our knowledge no study has yet examined associations between diet quality and body composition in VLBW individuals.ObjectiveThe objective of this study was to determine associations between Healthy Eating Index-2010 (HEI-2010) scores and consumption of fruits/vegetables, added sugars, and macronutrients with body composition in 5.5-y-old children born VLBW. We hypothesized HEI-2010 scores were inversely associated with adiposity.MethodsThis cohort study leveraged the 5.5-y follow-up to the Donor Milk for Improved Neurodevelopmental Outcomes randomized controlled trial. From June 2016 to July 2018, participants attended a follow-up visit at The Hospital for Sick Children, Canada, or were visited in their home. All 316 surviving infants from the trial were eligible, and the caregivers of 158 children (50%; 53% male) consented to follow-up. Diet quality (HEI-2010) and usual intake of fruits/vegetables, added sugars, and macronutrients were determined from two 24-h dietary recalls (ASA24). Linear regressions evaluated associations of diet with BMI (kg/m2) and waist circumference z-scores, total fat, fat-free mass (air displacement plethysmography), and skinfolds.ResultsMean ± SD age at follow-up was 5.7 ± 0.2 y, birth weight was 1013 ± 264 g, and gestational age was 27.9 ± 2.5 wk. Dietary data and BMI z-scores were available for all children; 123 completed air displacement plethysmography. HEI-2010 score was 58.2 ± 12.4 out of 100, and 27% of children had poor quality diets (scores ≤50). HEI-2010 scores were inversely associated with BMI z-score, but only in children with obese mothers. A 10-point increase in HEI-2010 score was associated with reduced BMI (β: -0.5 SD; 95% CI: -0.7, -0.2) and subscapular (-0.3 SD; 95% CI: -0.6, -0.06) z-scores.ConclusionsImproving diet quality in children born VLBW with obese mothers may be an important strategy to prevent excess adiposity. This trial was registered at clinicaltrials.gov as Optimizing Mothers' Milk for Preterm Infants (OptiMoM) Program of Research: Study 1-Impact of Donor Milk at Kindergarten, NCT02759809.
