OBJECTIVES/SPECIFIC AIMS: The majority of obese adults do not become obese until adulthood. Although adults spend the equivalent of a 40-hour work week in front of the television (TV), there are mixed data on whether the sedentary behavior of TV viewing is linked with weight gain during adulthood. The purpose of this study was to examine the associations among sedentary behavior, measured as TV viewing and TV in the bedroom, with eating behavior, eating attitudes and cravings, fat gain, and blood pressure in healthy young adults over a 2-year period. METHODS/STUDY POPULATION: The sample included 73 healthy, nonobese adults (56% women, 80% white) who were 26.8±4.5 years of age with a body mass index of 22.9±2.4 kg/m2. Participants completed clinic visits at baseline and 2-years later (Year 2) which assessed weight, height, blood pressure, waist circumference, and total body fat measured by dual energy X-ray absorptiometry. A food frequency questionnaire was used to estimate dietary intake, and the eating inventory was used to assess dietary restraint, disinhibition, and hunger. At baseline, participants self-reported TV habits including number of hours/week of watching TV (including cable, VCR, DVD) and presence of a TV in the bedroom. For the analysis, participants were stratified by quartiles of TV viewing time. T tests were used to examine the association between TV viewing and bedroom TV. Linear regression models were used to examine the association between TV viewing and each anthropometric and body composition measure and change over the 2-year period, as well as with the dietary constructs. Models controlled for age, sex, and baseline body fat. Separate models were used to investigate the associations between bedroom TV and the same dependent variables. RESULTS/ANTICIPATED RESULTS: Participants reported an average of 13.3±10.8 hours/week of TV viewing, with 33.3% reporting a TV in the bedroom. There were no differences in age, sex, or race among the quartiles of TV viewing or between those who did and did not have a bedroom TV. Adults with a bedroom TV did not differ in hours/week of TV viewing compared with those without a bedroom TV. Amount of TV viewing was associated with higher systolic blood pressure at baseline (p=0.05) but with no other anthropometric or body composition indices nor with change in body composition over the 2-year period. Adults with a bedroom TV reported higher craving for sweets at baseline (p=0.03). Amount of TV viewing was related to lower consumption of vegetables (p=0.04) and fruit or fruit juice (p=0.03) at Year 2, but there was no association with total calorie consumption. TV viewing and bedroom TV were not related to dietary restraint, disinhibition, or hunger at either time point. DISCUSSION/SIGNIFICANCE OF IMPACT: Adults who watched more TV consumed fewer fruits and vegetables, and those with a TV in the bedroom reported higher craving for sweets. Though there were no observed relationships between TV habits and body composition change, the associations with cravings and food consumption warrant further exploration. Querying young adults’ TV and media use habits in clinical settings may alert physicians to those at risk of developing poor dietary habits.

(1) Background: The preoccupation with the increasing appearance of eating disorders (ED) in athletes continues to grow, especially in athletes who practice team sports. ED severely affects the eating habits of the athletes, who tend to use unhealthy approaches to control their body weight. The development of nutritional education and early interventions by training staff is essential, and these factors are widely perceived as beneficial in sports medicine. This study evaluates the frequency at which beach handball (BH) players develop ED, also comparing the differences by sex and age (junior: adolescents vs. senior: young adults). In addition, the relation between body composition variables and ED was studied. (2) Methods: A descriptive and cross-sectional study was carried out in 69 top elite handball players (36 males and 33 females) from the Spanish National BH Team; who were separated by age (junior: adolescents and senior: young adults). The athletes completed the Eating Attitudes Test in its 26 item version (EAT-26). (3) Results: The prevalence of ED indicated that 11% of females had a high possibility of developing an ED, and 3% of males. Regarding the EAT-26 total score and subscales, no significant differences were found between female and male participants, or between the junior and senior categories. The correlations showed an association between body composition, in terms of body mass index, and the EAT-26 total score in both males and females. In the case of males, the correlation was negative. (4) Conclusions: Although there are no significant differences between sex or categories, it has been found that elite athletes are a population that is at high risk of developing ED.

Tv Viewing

Background: Sedentary behaviors (SB) are activities associated with prolonged time periods of sitting, reclining, or laying down during waking hours. While the relation between SB and physical activity is complex, the common consensus is that SB is not the absence of physical activity and consists of its own determinants posing distinct health outcomes. These behaviors are of significant public health importance as the majority of Americans spend much of their days in SB and due to the increased risks of morbidity and mortality associated with SB. Adverse health outcomes associated with SB include cardiovascular disease, obesity, metabolic syndrome, hypertension and mortality. Television-viewing time and total sitting time have both been used widely to assess time spent in SB and therefore we hypothesize that TV-viewing time and total hours sitting will have high concordance and can be used interchangeably to represent sedentary behaviors. Methods: Using a sample (n = 2858) from the Images of a Healthy Worksite study, a group-randomized control trial involving nutrition and physical activity, the current study assessed how two different tools measured time spent in SB. Tertiles were created based upon the distribution of hours sitting and hours spent TV-vewing. Weighted Kappa statistics were used to measure concordance between hours of TV-viewing and total hours of time spent sitting for the entire sample and for subgroup analyses. Results: Weighted Kappa statistics for tertiles of hours sitting and tv hours were 0.0046, indicating little agreement on the television and the sitting items. Kappa w statistics for BMI categories also showed poor agreement (obese Kappa w = 0.02, overweight Kappa w = 0.002, and healthy subjects Kappa w = 0.006. The Kappa w statistics for males and females were -0.006 and 0.02, respectively. Kappa w statistics for the intervention group (Kappa w = 0.007) and for the control group (Kappa w = 0.0005) also showed little agreement. Conclusions: These results suggest that although commonly used, using television viewing time and total time spent sitting as interchangeable markers of SB, is not a valid assumption. We propose that total time spent sitting and hours spent television-viewing represent different domains within the construct of sedentary behavior. It is important for future researchers to use measures of sedentary behavior that capture the numerous domains involved in measuring SB to allow for the most sensitive measurement of this high-risk behavior.

Introduction: Pericardial adipose tissue (PAT), an ectopic adipose depot surrounding the coronary arteries, is a pathogenic risk factor for cardiometabolic disease; however, the association of sedentary behavior with PAT is poorly understood. We examined the longitudinal association of 10-year change in TV viewing with concurrent change in PAT. Hypothesis: Increased h/day of TV viewing over 10 years are associated with larger mean increases in PAT during the same 10-year period. Methods: Middle-aged adults (N=1659, mean age=40.4, 912 females, 733 blacks) from the Coronary Artery Risk Development in Young Adults (CARDIA) Study at the exam years 15 (2000-2001) and 25 (2010-2011) were included. Both TV viewing (h/day) and the volume of PAT (mL) were measured at Years 15 and 25 using the CARDIA physical activity questionnaire and computed tomography, respectively. Covariates measured at year 15 included PAT, sociodemographic factors, cardiovascular disease risk factors, diet quality, TV viewing, moderate-to-vigorous intensity physical activity (MVPA), inflammatory cytokines, and waist circumference. Multivariable linear regression was used to estimate 10-year change in PAT across increasing tertiles (≤ -1, > -1 to < 1, ≥ 1 h/day) of 10-year changes in TV viewing. Results: On average, TV viewing and PAT increased between the two exam years by 0.2 h/day (8.7% increase, mean: 2.3 → 2.5 h/day) and 11.8 mL (25.9% increase, mean: 45.6 → 57.4 mL), respectively (all p < 0.01). In the fully adjusted model including MVPA and other major confounders, the highest tertile of 10-year change in TV viewing was associated with greater change in PAT (β = 2.97 mL, p < 0.01) when compared with the lowest tertile (see Figure 1 ), while mean PAT change was intermediate in the middle tertile. Conclusions: A greater 10-year increase in TV viewing is associated with a greater concurrent increase in PAT, independent of MVPA and other important confounders. Reducing TV viewing time may be associated with less PAT accumulation with age.

Introduction: Causes of obesity, a leading risk factor for chronic disease morbidity/mortality, are multi-faceted and encompass behavioral and psychological factors. Understanding eating behavior can help target behavioral obesity interventions. The aim of this cross-sectional study was to examine cognitive restraint (CR), uncontrolled eating (UE) and emotional eating (EE) behaviors and body composition in a sample of Chilean young adults. Methods: Using data from 429 participants of the Santiago Longitudinal Study (mean age 22.5±0.4 years), evaluated from 2016-2017, linear and logistic regression models assessed the independent associations between three eating behavior dimensions, using the Three Factor Eating Questionnaire (1-4 range per dimension), and BMI, % body fat (measured by dual-energy x-ray absorptiometry), and central obesity, accounting for demographic covariates, stratified by sex. Results: The sample was 51% female and had a mean BMI of 26.9±6.1. Mean % body fat was 30.5±7.6 in males and 41.8±6.9 in females. CR and EE eating behaviors were associated with body composition measures as shown in the Table 1. CR was related to a 2.4 (95% CI 1.2, 4.8) and 2.5 (95% CI 1.4, 4.5), respectively, greater odds of being an obese male (>25% body fat) and obese female (>37% body fat). The EE dimension was also significantly associated with percent body fat in both sexes. The greatest effect size in the linear regression models was observed for central obesity. For every point increase in CR, waist circumference increased by 5.1 cm (95% CI 2.1-8.1) and 4.1 cm (95% CI 1.5-6.7) in males and females, respectively. EE was positively associated with central obesity in females. Conclusions: In this sample of Chilean young adults, CR and EE eating behavior dimensions were associated with obesity, central obesity and% body fat. The UE dimension was not associated with body composition. Understanding the dynamics of and interplay of eating behaviors and body composition can provide evidence for future effective interventions.

We assessed changes in body composition in 41 young adults who engaged in various exercise and/or training programs on ad libitum diets. Most of those who gained weight sustained an increase in lean body mass (LBM), and most of those who lost weight lost LBM as well as fat. The change in LBM was directly related to the change in weight, with a regression slope of 0.500. An analysis of published data confirms these findings and, in concert with our data, provides the additional information that the magnitude of the change in body composition in exercising individuals is influenced by body fat content, just as it is for nonexercising individuals.

Context: Professional football linemen are at risk for sleep-disordered breathing (SDB) compared with other types of athletes. It is currently unknown whether college football linemen display a similar risk profile. Objective: (1) To determine for the first time whether college football linemen show risk for SDB and (2) test the hypothesis that SDB risk is higher in college football linemen compared with an athletic comparison group. Design: Descriptive laboratory study. Setting: The Health Risk Assessment Laboratory. Participants: Male football linemen (n = 21) and track (n = 19) Division I athletes between the ages of 18 and 22 years. Interventions: Participants completed the Multivariable Apnea Prediction Index and Epworth Sleepiness Scale surveys, validated measures of symptoms of sleep apnea and daytime sleepiness, respectively. Neck and waist circumferences, blood pressure, Modified Mallampati Index (MMPI), and tonsil size were determined, followed by body composition assessment using dual-energy X-ray absorptiometry. Main Outcome Measures: Scores from surveys, anthropometric data, MMPI, and body composition. Results: Survey data demonstrated a deficiency in sleep quality and efficiency, coinciding with increased self-reported symptoms of apnea (Multivariable Apnea Prediction Index = 0.78) in college linemen relative to track athletes. Neck circumference (44.36 cm), waist circumference (107.07 cm), body mass index (35.87 kg/m2), and percent body fat (29.20%), all of which exceeded the clinical predictors of risk for obstructive sleep apnea, were significantly greater in linemen compared with track athletes. Multivariable Apnea Prediction variables were significantly correlated with MMPI, neck circumference, percent body fat, body mass index, and systolic blood pressure (r ≥ .31, P < .05), indicating that college football linemen are at increased risk for SDB. Conclusions: Risk factors for SDB recognized in professional football linemen are also present at the college level. Screening may minimize present or future risk for SDB, as well as the downstream risk of SDB-associated metabolic and cardiovascular disease.

Background. Female adolescents are considered a risk group for cardiometabolic disease due to their lifestyle (LS). Objective. To evaluate the association between LS classes and body composition groups with cardiometabolic disease risk factors and pro- and anti-inflammatory biomarkers in female adolescents. Methods. This cross-sectional study was carried out with female adolescents aged 14 to 19 years, from Viçosa-MG, Brazil. Latent class analysis assessed LS classes. Kinanthropometric measurements were taken together with the body fat percentage (BF%), being analyzed by the Dual Energy X-ray Absorptiometry (DEXA) equipment. Blood pressure and biochemical parameters were analyzed in the Health Division of the Federal University of Viçosa. The pro- and anti-inflammatory biomarkers were analyzed using Luminex technology. Associations with biomarkers were estimated by multiple linear regression. Results. 405 female adolescents were evaluated. The majority, 82.57%, 72.90%, and 65.31%, were classified as inactive by the number of steps, with high screen and cell phone time, respectively. Furthermore, 41.55% did meet the minimum of 60 minutes of moderate-to-vigorous physical activity (MVPA) and 54.69% had high values of BF% (DEXA). The “Sedentary & Inactive LS” class together with the high levels of weight and BF% were associated with increased levels of blood pressure, lipid profile, and uric acid. It was also found that “Inactive & Sedentary LS”, high BF%, insulin resistance, and ultra-sensitive C-reactive protein were associated with the concentrations of proinflammatory biomarkers of tumor necrosis factor-α, interleukin-6, and leptin. Conclusion. We concluded that female adolescents with overweight/obese and high BF% presented higher values of anthropometric indicators, levels of blood pressure, concentration of uric acid and hs-CRP, and lower concentration of HDL. Inactive and Sedentary lifestyle of these girls, along with excess body fat, insulin resistance, and higher concentrations of hs-CRP were associated with the higher concentration proinflammatory markers.

Abstract Objectives To examine the association between meal habits (i.e., eating breakfast every day, usually ≥80% fullness at breakfast, and not eating snacks at night), body composition and the subsequent changes in mood status in young adults. Methods This is a longitudinal follow-up study based on a randomized trial (ClinicalTrials.gov Identifier: NCT03828812). Young adults were recruited based in a university campus in Taipei City, Taiwan. In total, 125 participants were recruited and 103 completed the follow-ups. Measured body composition (TANITA BC-418) and moods (Depression Anxiety Stress Scale, DASS) were assessed at baseline, the third month and 15th month from baseline. Baseline meal habits were based on the participants’ recall of their diets in the month before interview. We used mixed-effect model to test the association of baseline total body fat percentage and trunk body fat percentage and moods during follow-ups, adjusting for age, sex, baseline body mass index (BMI), food security status. Results After controlling for sex, age, BMI, and food security status at baseline, having breakfast every day at baseline was associated with 2.04 (se = 0.78, P = 0.0098) lower anxiety score and with 2.58 (se = 1.26, P = 0.0409) lower stress score at baseline. Meal habits were not associated with the subsequent changes in mood status. As for body composition, one % of trunk body fat replacing one % of non-trunk body fat at baseline was associated with 1.19 (se = 0.57, P = 0.0381) higher depression score, 1.02 (se = 0.47, P = 0.0327) higher anxiety score, 2.06 (se = 0.76, P = 0.0075) higher anxiety score at baseline. One % of non-trunk body fat percentage was associated with 2.60 (se = 1.02, P = 0.0116) lower anxiety score, as trunk body fat % is controlled. Baseline body fat composition parameters were not associated with the temporal changes in mood scores. The significance patterns were similar after adjusting for baseline physical activity level, assessed by International Physical Activity Questionnaire. Conclusions Breakfast habits and body composition, especially trunk body fat, was associated with university-based young adults’ emotional health status.
