Achievement goal orientations have a significant impact on students' self-regulation and development. An individual's achievement goal orientations may change at some critical stages. The sample of this study came from a survey of college students conducted in China for four consecutive years. The study used a growth mixture model to identify the longitudinal trajectories of achievement goal orientations during the college years, constructed a logistic regression model to analyze the related factors of students in different classes, and further examined the effects on academic performance. The results indicate that the longitudinal trajectories of all the 2 × 2 achievement goal orientations can be divided into decreasing class and increasing class. Taking the increasing class as the reference, extroversion, high BMI, high sleep duration, and major are related factors of students in the decreasing class of performance-approach goals. Extroversion and father's education level are associated with students in the decreasing class of mastery-avoidance goals. Extroversion, high sleep duration, father's education level, family economic status, and family social status correlate with students in the decreasing class of mastery-approach goals. In addition, there are significant differences in the academic performance of students in different trajectory classes.

Purpose: The study aimed to test the overall changes of health-related fitness (HRF) in minority Chinese college students and to examine HRF differences in gender, race, and year in college. Method: Participants (n = 1320) were minority college students with more than two-thirds females (ie 76.1%), and Hui, Tibetan, and Mongolia consisted of 13.8%, 13.8%, and 11.2%, respectively. Student HRF was tracked for four years. Data were analyzed using multilevel latent growth curve modeling. Results: Muscular strength and endurance were the weakest component in minority college students' HRF, while body mass index was within the category of "excellent". Males outperformed female on all components of HRF. Conclusions: It is suggested that interventions concerning minority females' HRF and muscular strength and endurance for both genders be constructed and tested.

Eight percent of adolescent girls were found to be engaged in problematic social media use. Problematic social media use is associated with serious physical and mental consequences. This study aimed to explore the effects of thin-ideal internalization on problematic social media use and the role of selfie-related behaviors and friendship quality. We recruited 903 Chinese adolescent girls with an average age of 13.73 years (ranging from 11 to 16 years) recruited to complete the self-report questionnaire, which contained four measures. Results revealed a moderated mediation model. Girls who had internalized thin-ideal images were more vulnerable to social media's addictive properties, constantly engaged in selfie-related behaviors, and developed subsequent problematic social media use. However, for adolescent girls, high friendship quality buffered against developing problematic social media use, despite selfie-related behaviors. The study provides suggestions to reduce problematic social media use among adolescents to promote their physical and mental health.

The outbreak of the COVID-19 pandemic has caused increasing concern over health care, part of which involves the role of nutrition. In this study, a nutrition educational board game, featuring quantitative computation, was designed to help students acquire nutrition knowledge and improve dietary behaviors. A group of 22 students in grade 7 of a middle school in Beijing were selected as the participants. A single-group pre- and post-test quasi-experimental design was adopted. Knowledge-Attitude-Practice (KAP) questionnaires and interviews were used to investigate students' changes in dietary knowledge, attitude, and behavior. The influence of gender and body mass index (BMI) on the teaching effectiveness was also explored. The results showed that some dimensions of knowledge, attitude, and behavior significantly increased in the students. Their changes in behavior were mainly related to some aspects that were easier to adjust. In addition, the study also found that females and students with abnormal BMI were more likely to be influenced by the educational game to make positive changes in attitude and behavior.

Objectives: To characterize the health behaviors and outcomes of first-year international students (FYIS) studying in the U.S. Participants and methods: Three different cohorts of FYIS from a large midwestern university in the U.S. completed three laboratory visits between August and March. The study began in 2017 and ended in March 2020. Anthropometrics, acculturative stress, eating behaviors, sleep, physical activity, and eating habits were assessed. Results: Fifty-four students completed the study. Females had a significant increase in percent body fat (p = 0.036) and a decrease in sleep quality (p = 0.006) at the final visit vs. baseline, and uncontrolled (p = 0.006) and emotional (p < 0.001) eating behaviors were higher. FYIS who gained more than the median 1.2 kg over the study period experienced higher acculturative stress (p = 0.004) and a decline in sleep quality (p = 0.003). Conclusion: Reducing acculturative stress and improving sleep quality should be explored as interventions to protect against undesirable changes in adiposity among FYIS.

Purpose: This review systematically analyzed BID among young women of developing nations after these women's consumption of Western media. We explored changes in women's exposure to Western media alongside changes in body image dissatisfaction and eating disorders. Reoccurring themes of internalization across populations of women are discussed. Method: Multiple databases were used in our search for relevant research which included information on body image dissatisfaction, eating disorders, Western media, and the experiences of young women. Ultimately, given the extant research and specific interests of the current study, body image dissatisfaction was explored within the following ten nations: Turkey, India, China, South Africa, Belize, Zimbabwe, Malaysia, Iran, Oman, and Fiji. Results: Many of the identified research studies included "secondary and post-secondary students as their sample." Results lend further support for the association between Western media and body image dissatisfaction and eating disorders across cultures and developing nations. Internalizing thin ideals into a woman's current cultural beauty schema, her amount of exposure, and her socioeconomic status emerged as important predictors of body image dissatisfaction. Implications for Research and Practice: Results of the current study suggest that young women of developing nations may associate the thin ideals portrayed in Western media with financial success. This association warrants further exploration and could inform more culturally sensitive interventions. An attempt to understand the importance of cultural differences and similarities would be a progressive step in identifying appropriate mechanisms on which interventions might act to prevent internalizing harmful aspects of the beauty ideals presented in Western media.

Guided by the Transtheoretical Model (Prochaska & DiClemente, 1982), this study investigated the differences of physical activity levels and correlates (i.e., self-efficacy, decisional balance, process of change) across different stages of change levels among Chinese college students. The relationships between students' physical activity correlates and physical activity behavior was also examined. The participants were 887 college students (365 males; M[subscript age] = 20.51, SD = ± 1.67) recruited from four universities in south and south-canter China. Participants completed a battery of established questionnaires assessing their physical activity correlates (self-efficacy, decisional balance, process of change) and 1-week physical activity levels. Results suggested that Chinese college students in the high stage of change group reported significantly higher physical activity levels and correlates than those in the low stage of change group. Pearson correlation analyses suggested that students' self-efficacy was moderately related to other correlates and physical activity behavior. Yet, decisional balance and process of change were only modestly associated with physical activity levels for both groups. Regression analyses further revealed students' self-efficacy emerged as the only significant contributor of their daily PA levels across the two groups. However, decision balance and process of change failed to predict physical activity levels. The implications for practice and direction of future research were discussed.

The study aimed to explore Chinese university administrators' physical activity (PA) levels and its relationships to self-rated health and body mass index (BMI). A pre-validated survey was used to collect the data. In total, 443 participants took part in the study. The percentages of participants meeting the recommended PA and BMI were calculated. MANOVA was performed to analyze the PA differences in age and gender, and BMI and self-rated health, respectively. It was found that 75.2% of the participants did not meet the recommended PA and 43.8% of them were overweight and/or obese. Self-rated health was a significant factor influencing their light PA only. No gender differences in PA were found, however. The data from the study suggested that there was an urgent need to promote healthy lifestyles among Chinese university administrators by increasing their PA levels and reducing the prevalence of weight problems.

Background: Limited research has examined health and fitness indicators among individuals with different categories of intellectual disabilities (ID). The purpose of this brief report was to examine differences in health and physical fitness indicators among individuals with different levels of ID. Method: Individuals (n = 203) with mild, moderate, and severe ID completed a health and fitness screening. The health screening included blood pressure and lung capacity. Fitness measures were body composition, balance, and strength. We conducted multivariate analysis of covariance (MANCOVA) to examine level differences, controlling for age and gender. Results: Individuals with severe ID had significantly lower lung capacity than those with moderate ID, who had lower than those with mild ID. Individuals with mild ID had significantly higher handgrip strength than those with moderate ID, who had higher strength than those with severe ID. Conclusions: Lung capacity and handgrip strength are sensitive health and physical fitness risk markers for ID levels in China.

The purpose of this study was to investigate the exercise intensity and the physical fitness effect of shuttlecock playing. 18 normal body weight college students voluntarily participated in this study. They were randomly assigned to shuttlecock playing (SCP) and control groups. The SCP underwent a 15-week shuttlecock-playing program, but the control group did not receive any special exercise activities. The program was arranged as follows: SCP underwent 4 sessions/week, 3 sets/session, 10 min/set, and rest 5 min between set. The results indicated that systolic pressure, abdominal skinfold, continuing work time, and hip joint flexibility of SCP were significantly improved after 12-week training. It has been concluded that a 15-week shuttlecock-playing program could remarkably promote the physical fitness for college students in body characteristics, body flexibility, and aerobic fitness but not muscular strength in lower limbs.

Purpose: Previous studies indicated a positive association between physical education (PE) and mathematics achievement (MA). This study explored how PE curriculum implementation relates to MA using data from the China National Assessment of Education Quality (CNAEQ) in 2015, including Mathematics (CNAEQ-MA 2015) as well as Physical Education & Health (CNAEQ-PEH 2015). Method: This study included 22,619 students (48.7% girls) age 13.96 ± 0.64 yr. from the national sample of Grade 8 students from CNAEQ. During 2015, MA and cardiorespiratory fitness (CF) were assessed. PE curriculum implementation, personal hygiene, eating habits, PE interest, mathematics interest, and self-confidence were collected via a self-report student survey. Personal hygiene and eating habits were combined to create the latent variable, healthy lifestyle (HL). Structural equation modeling was applied to examine the associations. Socioeconomic status, school location, Body Mass Index (BMI), and sex were all controlled. Results: PE curriculum implementation had an indirect, positive association with MA through CF, HL-mathematics interest, and HL-mathematics self-confidence. Together, the model explained 27.8% of the variance in MA. Conclusion: PE curriculum implementation may benefit mathematics education, and this link is mainly through HL, CF, mathematics interest, and self-confidence.

Purpose: Physical education (PE) in school provides opportunities for physical activity (PA) engagement and reportedly results in improved health-related fitness. This study explored the underlying correlations between PE and activity-related healthy lifestyle practices with current level of cardiorespiratory fitness. Methods: A total of 13,138 students age 14 (boys = 7,094, 54.0%) in Grade 8 from the China National Assessment of Educational Quality - Physical Education & Health 2015 were included in this study. Two independent structural equation modeling (SEM) analyses were conducted to obtained sex-specific results. Data included the results of the 15-m progressive aerobic cardiovascular endurance run (PACER) and questionnaire data regarding PE curriculum implementation, learning and practice, perceived support from PE teachers, PE facilities, PE equipment, activity-related healthy lifestyle practices, habitual physical fitness, appropriate method of physical fitness, and breakfast eating habits. Structural equation modeling was applied to examine the associations between variables, controlling for socioeconomic status, the location of schools, and Body Mass Index. Results: There was a statistically significant relationship between cardiorespiratory fitness and activity-related healthy lifestyle practices, which was somewhat positively impacted by skill learning and practice and perceived support from PE teachers. Together, the boy's model explained 21.8% of the variance in cardiorespiratory fitness, whereas the girl's model explained 15.9%. Conclusions: A well-organized PE program is related to students' activity-related healthy lifestyle practices, and consequently provides an improvement to cardiorespiratory fitness.

Purpose: This study examined the prevalence of different weight status and the relationships between weight status and physical fitness among Chinese children and youth. Methods: Participants were 107,206 Grade 4 children and 70,213 Grade 8 youth from the China National Assessment of Educational Quality -- Physical Education & Health in 2015 (CNAEQ-PEH 2015). Using World Health Organization (WHO) and US Centers for Disease Control and Prevention (CDC) criteria, weight status was divided into four groups (underweight, normal weight, overweight, and obese) according to Body Mass Index (BMI). The differences of physical fitness performances (15-m progressive aerobic cardiovascular endurance run [PACER], standing long jump, and 50-m sprint) among four weight status groups were compared. Data were analyzed using descriptive statistics, MANCOVA, and Cohen's d. Results: The prevalence of weight status varied by criteria (e.g., for Grade 4 boys, the prevalence of underweight by WHO and CDC were 5.9% and 10.5%; overweight were 14.5% and 11.4%, respectively). Compared with the normal weight group, the selected physical fitness performances in the overweight and obese groups were worse (p < 0.001) with small to large effect sizes. Conclusion: The prevalence of underweight and overweight/obese was relatively high among Chinese children and youth. The prevalence of underweight, overweight, and obesity varied slightly depending on the criteria used for evaluating BMI. The overweight/obese participants tended to perform poorer in selected physical fitness tests. The performance disparities between the normal weight group and overweight/obese groups were larger in Grade 4 than in Grade 8 and among boys than among girls.

The present study aimed to examine the relationship between emotional intelligence (EI), social anxiety, and eating disorder risk as well as the effects of several demographic variables on social anxiety and eating disorder risk among adolescents in China. Seven hundred eighty-four senior high school students in China were sampled to participate in the survey, completing the measures of body mass index, Eating Attitudes Test (EAT-26), Wong and Law Emotional Intelligence Scale, and Liebowitz Social Anxiety Scale. Descriptive statistics, analysis of variance, and hierarchical regression with bootstrapping approach were used to examine the relationships between the studied variables. Adolescents' EI negatively influenced their social anxiety and eating disorder risk; meanwhile, their social anxiety acted as a partial mediator between their EI and eating disorder risk. In addition, gender, grade, and body size all had main effects on social anxiety and eating disorder risk, and there were interaction effects both between gender and grade, and between gender and body size. These findings advance our comprehending of the formation mechanism of EDs and should be helpful to conduct effective, targeted intervention on EDs among adolescents.

Ninety-four gifted children and 200 nongifted children (aged 9 to 13 years old) were involved in the present study. Their self-concept was assessed by the Revised Song-Hattie Self-Concept Inventory (Zhou & He, 1996). Academic self-concepts pertaining to abilities, school achievements, and grade concepts and nonacademic self-concepts pertaining to family, peers, body, and self-confidence concepts, as well as self-concept in general, were considered in the present study. The findings indicated that the development of self-concept in gifted children was different from that of nongifted children. Specifically, the self-concept scores in general of nongifted children increased from 11 to 13 years old, while those of gifted children decreased for the same age period. Both academic and nonacademic self-concepts are discussed in the present study. (Contains 2 tables.)

Purpose: The purpose of this study was to conduct a systematic review of classroom-based physical activity interventions that integrate academic content and assess the effectiveness of the interventions on physical activity, learning, facilitators of learning, and health outcomes. Method: Six electronic databases (ERIC, PubMed, Google Scholar, Science Direct, Cochrane Library, and EMBASE) and reference lists were searched for English-language articles, published January 1990 through March 2015, reporting classroom-based interventions that deliberately taught academic content using physically active teaching methods for at least 1 week duration, with physical activity, health, learning, or facilitators-of-learning outcomes. Two authors reviewed full-text articles. Data were extracted onto an Excel spreadsheet, and authors were contacted to confirm accuracy of the information presented. Results: Fifteen studies met the inclusion criteria. Six studies reporting on physical activity levels were found to have medium-to-large effect sizes. All 4 studies reporting learning outcomes showed positive effects of intervention lessons. Teachers and students were pleased with the programs, and enhanced on-task behavior was identified (n = 3). Positive effects were also reported on students' body mass index levels (n = 3). Conclusions: Physically active academic lessons increase physical activity levels and may benefit learning and health outcomes. Both students and teachers positively received and enjoyed these teaching methods. These findings emphasize the need for such interventions to contribute toward public health policy.

This article reviews the results of a school-based self-management intervention for Chinese obese children at risk for metabolic syndrome. Twenty-eight Chinese obese children (M age?=?10 years) and their parents participated in the study. Metabolic syndrome risk factors were measured pre- and post-intervention. The risk factors included Body Mass Index, waist circumstance, systolic blood pressure, diastolic blood pressure, triglycerides, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, High-sensitivity C-reactive Protein, fasting plasma glucose, and fasting blood insulin. After 6 months of school-based self-management intervention, all risk factors with the exception of triglycerides and fasting plasma glucose changed significantly in the healthful direction (p?

Objective: To identify levels of moderate-intensity physical activity (MPA) and vigorous-intensity physical activity (VPA) in a representative sample of college students in six East Asian economies and examine their relationship with weight, alcohol consumption and cigarette smoking. Design: Cross-sectional survey. Setting: College students recruited from 21 different colleges in six East Asian economies. Method: Self-reported physical activity, weight, height, alcohol consumption, and smoking were assessed using already-validated instruments. Multiple logistic regression models of MPA and VPA were separately performed for each economy, controlling for age, gender, living area before college, military experience, paid employment, and religion. All the analyses were performed using SAS 9.2 with clustering effects accounted for. Results: Being a heavy drinker increased the odds of engaging in VPA in five economies (adjusted odds ratio [AOR] = 1.56 to 2.65). Cigarette smoking was not associated with MPA in any economy and was only associated with VPA in China (AOR = 1.54) and Taiwan (AOR = 1.48), indicating that smokers are more likely to engage in VPA than non-smokers. Conclusions: The relationship between college students' VPA and alcohol consumption and between MPA and cigarette smoking is similar across the East Asian economies, whereas the relationship between VPA and smoking varies substantially.

Purpose: The purpose of this study was to objectively assess levels of physical activity (PA) and sedentary behavior (SB) of Chinese city children and youth aged 9 to 17 years old using accelerometers and to examine their differences by gender, age, grade, and weight status. Method: The PA and SB of 2,163 students in 4th grade through 11th grade ("M"[subscript age] = 160.87 ± 27.00 months [13.41 ± 2.25 years], 50.21% boys) from 11 cities in China were measured by accelerometers. The amount of time spent in SB, light PA, moderate PA, vigorous PA, and moderate-to-vigorous PA (MVPA) was computed based on cutoff points developed specifically for the Chinese children and youth. The participants were classified into normal-weight, overweight, and obese groups based on their body mass index (BMI). Paired-sample "t" tests were conducted to examine the differences in PA and SB between weekdays and weekend days. Multivariate analysis of variance was used to test the differences in PA and SB variables by gender, age, grade, and weight status, respectively. Results: Chinese city children and youth spent an average of 28.26 ± 17.66 min/day in MVPA and 521.50 ± 110.02 min/day in SB. Only 9.4% of boys and 1.9% of girls met the recommendation of 60 min/day of MVPA. Chinese city children and youth were more active during weekdays than during weekend days, and boys were more active than girls; older children and youth spent more daily time in MVPA, but also spent more time being sedentary. No differences in PA and SB were found across different BMI categories. Conclusion: The findings warn of the insufficiency of PA and the excess of SB in Chinese city children and youth.

Despite the recent and rapid worldwide rise in body mass index (BMI), little empirical research outside the developed world has systematically considered the role of cohorts in inaugurating emergent biomorphic disparities. This study integrates aspects of the life course perspective (attention to age- and cohort-level influences) with fundamental cause theory to investigate how BMI differences have unfurled in the Chinese population. We analyze growth-curve models of adults in the China Health and Nutrition Survey. The results indicate that more recent cohorts have higher levels of BMI and, among women, experience a steeper rate of age-related BMI growth. Moreover, biomorphic change has unfolded in complex ways related to social conditions across successive cohorts. The most pronounced changes are observed among women, who demonstrate an emerging disparity in BMI levels on the basis of education and urban versus rural residence.

Students' different perceptions of task values influence their learning experience and achievement in physical education. Framed using the subjective task value construct, this study was conducted to determine the extent to which male and female Chinese middle schoolers with different body sizes differed in their perception of the task values. A second goal of the study was to identify the extent to which the task values along with gender and body size predicted students' performance on knowledge and physical skill tests. Data from a random sample of students (N = 860) from eight Chinese middle schools revealed that the boys appreciated intrinsic (p = 0.001) and utility values (p = 02); both boys and girls, however, equally appreciated the attainment value (p = 0.73). The boys performed better in physical skill tests than the girls (p = 0.001), whereas the girls scored higher in knowledge tests than the boys (p = 0.04). Regression analyses revealed that gender is the only predictor for performance on both knowledge and skill tests. Utility value and body size were predictors for skill, not for knowledge. These findings indicate that Chinese middle school boys and girls differed in valuing and achieving in physical education. The findings imply that Chinese boys need to strengthen cognitive learning and girls need to strengthen psychomotor skill development in physical education. (Contains 6 tables.)

From a large school-based sample (N = 3,084), 49 Mainland Chinese adolescents (31 girls, 18 boys) who endorsed all DSM-IV criteria for bulimia nervosa (BN) or sub-threshold BN and 49 matched controls (31 girls, 18 boys) completed measures of demographics and sociocultural experiences related to body image. Compared to less symptomatic peers, those in the BN group reported higher levels of appearance pressure from their network of close relationships and mass media, appearance comparisons and conversations, and fear of negative appearance evaluation. A hierarchical logistic regression analysis based seven predictors resulted in the correct identification of 82.7% of respondents, including 83.7% of the BN group and 81.7% of controls. Responses on sociocultural measures, especially those reflecting appearance pressure, added to the classification rate, after controlling for body mass index and household socioeconomic status. When repeated within each sex, classification accuracy was 90.3% for girls and 86.1% for boys. This study establishes clear links between sociocultural influences and BN among urban adolescent girls and boys living in the People's Republic of China.

Weight and body image concerns are prevalent among adolescents across cultures and pose significant threats to well-being, yet there is a paucity of longitudinal research on samples living in non-Western and developing countries. This prospective study assessed the extent to which select sociocultural, psychological, and biological risk factors contributed to changes in weight esteem among adolescent girls and boys living in the People's Republic of China. Students (181 boys, 320 girls) from middle schools and high schools in Southwest China completed measures of demographics; weight esteem; thin female and lean, muscular male appearance ideals; positive and negative affect; and appearance-based social pressure, teasing, and comparison. Subsequently, weight esteem was reassessed 18 months later. Girls having stronger preferences for thin ideals, a high body mass index, and more negative affect at Time 1 were more likely to experience losses of weight esteem at follow-up. Among boys, high baseline levels of appearance pressure contributed to later reductions in weight esteem--an effect that was also moderated by age. For both sexes, appearance social comparisons also contributed to weight esteem changes in univariate analyses, albeit these effects were attenuated within multivariate prediction models. In sum, this study highlights how specific experiences implicated previously in research on body dissatisfaction in Western samples are also salient in understanding changes in weight esteem for adolescent girls and boys in rapidly developing China.

The height, weight and BMI of children with autism was investigated and analyzed to find the physical status of children with autism in China. Three hundred and eighty boys and 49 girls diagnosed with autistic disorder participated. Their parents were interviewed with a questionnaire about general information, and children were evaluated with Childhood Autism Rating Scale, and height and weight were measured. Children with autism had high level height, weight and BMI; the rate of height greater than or equal to P[subscript 75] was less in 6-11 years old group than that in 2-5 years old group in boys and all children. The prevalence of at-risk-for or being overweight was 31.8% and 17.0% in 2-5 years old group, were 37.9% and 21.8% in 6-11 years old group. At-risk-for-overweight/overweight of children with autism had no relationship with their core symptoms, the older age was the only predictor for lower height and at-risk-for-overweight. Prevalence of at-risk-for-overweight and overweight in children with autism was high. Children's height level decreased, and being at-risk-for-overweight increased with age. (Contains 4 tables.)

This 18-month prospective study investigated factors that contributed to changes in eating disorder symptoms among adolescents living in the People's Republic of China. Five hundred forty-one Chinese middle school and high school students (182 boys, 359 girls) completed measures of eating disorder symptoms; body dissatisfaction; appearance ideal endorsements; negative affect; and appearance-based social pressure, teasing, and comparison. For girls, baseline levels of negative affect, preference for a thin appearance ideal, and fatness concern made unique contributions to reported eating disturbances at the 18-month follow-up. For boys, baseline body mass index and fatness concerns were the only significant univariate predictors of changes in eating pathology. (Contains 5 tables.)

Childhood obesity is increasingly prevalent in Western and non-Western societies. The authors related multiple dimensions of physical self-concept to body composition for 763 Chinese children aged 8 to 15 and compared the results with Western research. Compared with Western research, gender differences favoring boys were generally much smaller for physical self-concept and body image. Objective and subjective indexes of body fat were negatively related to many components of physical self-concept, but--in contrast to Western research--were unrelated to global self-esteem and slightly positively related to health self-concept. In support of discrepancy theory, actual-ideal discrepancies in body image were related to physical self-concept. However, consistent with the Chinese cultural value of moderation, and in contrast to Western results, being too thin relative to personal ideals was almost as detrimental as being too fat. The results reflect stronger Chinese cultural values of moderation and acceptance of obesity than in Western culture and have implications for social and educational policy in China.

We compared health status, anthropometric and psychological development of 123 children adopted before 18 months of age from China, East Asia (Vietnam, Taiwan, Thailand, South Korea, Cambodia), and Eastern Europe (mostly Russia). Data were collected close to the time of arrival, and 3 and 6 months later. Anthropometric measures included weight, height, and head circumference percentiles, and weight/height and height/age ratios (indices of acute and chronic malnutrition, respectively). We assessed cognitive (MDI) and motor (PDI) developments with the Bayley Scales of Infant Development (Bayley, 1993). At time of arrival, children presented physical, cognitive, and motor delays, as well as health problems. Growth parameters improved with time, but differently among the groups. East Asian children, in a better physical state at time of arrival, changed less than the others did across time. Children adopted from Russia globally had lower MDI than the others, while children adopted from East Asia had the highest PDI. Hierarchical linear modelling indicated that initial MDI was related to height/age ratio (index of chronic malnutrition), while its change over time was related to age at time of arrival. PDI was also related to height/age ratio, as well as to presence/absence of neurological signs at time of arrival. Infants with a higher risk index had lower MDI and PDI initial scores.

This study examined the adult body shape preferences of 6- and 10-year-olds from the United States, Mainland China, and Turkey. Findings indicated that even the youngest children preferred thin, male and female figures and least preferred the very obese figures. Heavier female figures were chosen by Turkish children more than by other children. Anecdotal evidence revealed that Chinese children thought that the extremely obese figures did not exist.

Aims: Insulin resistance (IR) is an important risk factor for obesity and cardiometabolic diseases, and our previous findings have demonstrated that visceral fat area to skeletal muscle mass ratio (VSR) is significantly and positively associated with the risk of cardiometabolic diseases. Hence, this study aimed to investigate the relationship between VSR and multiorgan IR, provide a new approach to improve body composition, and set the basis for VSR to increase the incidence of cardiometabolic diseases. Materials and Methods: The study included 398 patients who underwent anthropometric and biochemical measurements, and body composition assessment. Spearman correlation analysis was used to investigate the correlation between VSR and homeostatic model assessment for insulin resistance (HOMA‐IR) as well as multiorgan IR, including homeostasis model assessment adiponectin (HOMA‐AD), adipose tissue insulin resistance (ADIPO‐IR), and hepatic insulin sensitivity (HISI). The new model that incorporated into the present study is made up of easily measured biochemical indicators and is used to predict IR. Logistic regression was used to analyze the odds ratio (OR) of VSR on the risk of multiorgan IR. The predictive value of VSR for HOMA‐IR and new model was evaluated using the receiver operating characteristic (ROC) curve. Results: VSR was significantly associated with HOMA‐IR, HOMA‐AD, ADIPO‐IR, 1/HISI, and new model (p < 0.001). With the increase of VSR, the OR increased significantly for HOMA‐IR and new model (p < 0.001). Then, multiorgan IR indicators were quantified, compared to the lowest quartile group, and increased VSR exacerbated the risk of IR in the highest quartile (ptrend < 0.001). The area under the curve for predicting IR using VSR for HOMA‐IR and new model was 0.88 for men, 0.85 for women and 0.73 for men, 0.76 for women, respectively. Conclusions: There was significant correlation between VSR and multiorgan IR, and the risk of multiorgan IR increased with increasing VSR. Trial Registration: Clinical Trial Registry identifier: ChiCTR2100044305. [ABSTRACT FROM AUTHOR]

Introduction: Handgrip strength and the 5‐time chair‐stand test are the two important muscle strength measures run through the whole sarcopenia diagnosis algorithm. There is a lack of evidence to confirm which muscle strength measures have a higher detection rate of sarcopenia among Chinese older adults, which is a challenge for community workers to choose the muscle strength measures and to identify more sarcopenia in clinical practice. Objective: We aimed to investigate the prevalence and diagnostic agreement of sarcopenia based on handgrip strength and the 5‐time chair‐stand test among Chinese community‐dwelling older adults. Methods: This cross‐sectional study sampled 1027 community‐dwelling older adults from Hunan, China. We used handgrip strength and the 5‐time chair‐stand test to assess participants' muscle strength and used gait speed and bioimpedance analysis (BIA) to assess physical performance and skeletal muscle mass, respectively. The kappa values of the agreement test were used to evaluate the agreement of handgrip strength and 5‐time chair‐stand tests in the assessment of sarcopenia. Results: A total of 1027 participants were included in this analysis including 337 males and 690 females with an average age of 70.35 ± 7.24 years. The prevalence of possible sarcopenia, confirmed sarcopenia and severe sarcopenia based on handgrip strength was 50.8%, 20.3% and 14.5% respectively, while the corresponding prevalence for using the 5‐time chair‐stand test was 27.6%, 10.8% and 10.9%. The kappa value of the consistency test between handgrip strength and 5‐time chair‐stand test in the assessment of possible sarcopenia, confirmed and severe sarcopenia was 0.26, 0.51 and 0.62, respectively (p < 0.001 for all). Conclusions: The prevalence of possible sarcopenia, confirmed sarcopenia and severe sarcopenia based on handgrip strength was significantly higher than that of the 5‐time chair‐stand test. We recommend handgrip strength as the preferred method of muscle strength measurement for Chinese community‐dwelling older adults and use 5‐time chair‐stand tests when handgrip strength is not available. Implications for Practice: The findings provide information and suggestions to healthcare providers for choosing the muscle strength measures to detect more sarcopenia in clinical practice. Compared with the 5‐time chair‐stand test, handgrip strength has a better performance to identify sarcopenia in Chinese community‐dwelling older adults. [ABSTRACT FROM AUTHOR]

Background: Obesity and sarcopenia are both viewed as pathological body composition issues and indicators of compromised nutritional status. The aim of this study was to evaluate the effects of sarcopenic obesity on short- and long-term clinical outcomes. Methods: The clinical data of patients who underwent radical gastrectomy between 2013 and 2019 were prospectively collected. Sarcopenia is defined by European Working Group on Sarcopenia in Older People (EWGSOP2) and obesity is defined by the body mass index (BMI). To identify the independent predictors of postoperative complications and overall survival, we performed univariate and multivariate logistic and Cox regression analyses. Results: In a total of 508 cases, 372 (73.2%) cases were diagnosed with non-sarcopenia, 112 (22.0%) with non-obese sarcopenia, and 24 (4.7%) with sarcopenic obesity. In the multivariate logistic regression, both of non-obese sarcopenia (OR = 2.305, 95% CI = 1.444–3.679, P < 0.001) and sarcopenic obesity (OR = 2.589, 95% CI = 1.088–6.156, P = 0.031) were independent risk factors for postoperative complications. In the multivariate Cox analysis, only non-obese sarcopenia (HR = 2.614, 95% CI = 1.882–3.631, P < 0.001) was independent risk factor for overall survival. Conclusions: Sarcopenic obesity serves as an independent risk factor for postoperative complications, but not for overall survival. [ABSTRACT FROM AUTHOR]

BACKGROUND: Evidence suggested that abiotic airborne exposures may be associated with changes in body composition. However, more evidence is needed to identify key pollutants linked to adverse health effects and their underlying biomolecular mechanisms, particularly in sensitive older adults. OBJECTIVES: Our research aimed to systematically assess the relationship between abiotic airborne exposures and changes in body composition among healthy older adults, as well as the potential mediating mechanisms through the serum lipidome. METHODS: From September 2018 to January 2019, we conducted a monthly survey among 76 healthy adults (60–69 years old) in the China Biomarkers of Air Pollutant Exposure (BAPE) study, measuring their personal exposures to 632 abiotic airborne pollutions using MicroPEM and the Fresh Air wristband, 18 body composition indicators from the InBody 770 device, and lipidomics from venous blood samples. We used an exposome-wide association study (ExWAS) and deletion/substitution/addition (DSA) model to unravel complex associations between exposure to contaminant mixtures and body composition, a Bayesian kernel machine regression (BKMR) model to assess the overall effect of key exposures on body composition, and mediation analysis to identify lipid intermediators. RESULTS: The ExWAS and DSA model identified that 2,4,5-T methyl ester (2,4,5-TME), 9,10-Anthracenedione (ATQ), 4b,8-dimethyl-2-isopropylphenanthrene, and 4b,5,6,7,8,8a,9,10-octahydro-(DMIP) were associated with increased body fat mass (BFM), fat mass indicators (FMI), percent body fat (PBF), and visceral fat area (VFA) in healthy older adults [Bonferroni-Hochberg false discovery rate (FDRBH)<0.05]. The BKMR model demonstrated a positive correlation between contaminants (anthracene, ATQ, copaene, di-epi-a-cedrene, and DMIP) with VFA. Mediation analysis revealed that phosphatidylcholine [PC, PC(16:1e/18:1), PC(16:2e/18:0)] and sphingolipid [SM, SM(d18:2/24:1)] mediated a significant portion, ranging from 12.27% to 26.03% (푝-value <0.05), of the observed increase in VFA. DISCUSSION: Based on the evidence from multiple model results, ATQ and DMIP were statistically significantly associated with the increased VFA levels of healthy older adults, potentially regulated through lipid intermediators. These findings may have important implications for identifying potentially harmful environmental chemicals and developing targeted strategies for the control and prevention of chronic diseases in the future, particularly as the global population is rapidly aging.

Objectives: This study aims to describe the differences in body composition among different body parts of the elderly in the community and its relationship with sarcopenia. Methods: Elderly people aged ≥65 underwent bioelectric impedance analysis testing and were categorized into a sarcopenia group, possible sarcopenia group, and control group. The characteristics of body composition indicators in different parts and their relationship with different stages of sarcopenia were analyzed. Results: The sarcopenia group illustrated the lowest values of FFM, FFM%, BFM, BFM%, ICW, and limb PhA, along with higher ECW/TBW in the trunk and left leg compared to the control group. The possible sarcopenia group showed lower FFM% in limbs and trunk, and higher BFM% compared to the control group. Gender differences in elderly body composition were observed, with an increase in BFM% in various body parts posing a risk factor for possible sarcopenia in elderly males, whereas an increase in BFM% except in the left arm was a protective factor for sarcopenia in elderly females. Conclusion: The body composition of the elderly in the community varied significantly in different stages of sarcopenia and genders, which correlated with sarcopenia. [ABSTRACT FROM AUTHOR]

China's population of older individuals reached 264.02 million in 2020, an increase of 5.44% from 2010. This study explores how participation in serious leisure sports, which have enduring benefits for older adults, contributes to active aging. In-depth interviews were conducted with 15 older participants aged 60–78 years who had participated in a leisure sport activity for 1 year or longer. A thematic analysis was conducted, and four themes emerged: body improvements, positive emotions, optimistic life attitudes, and social interactions. Older adults who participate in serious leisure sports are empowered via practice and learning opportunities to engage with their aging bodies, pursue psychological benefits, and jointly maintain leisure groups. The findings of this study contribute to our understanding of the "rights-based" approach to active aging and allow us to identify serious leisure sports as an active way for older adults to improve their quality of life.

BACKGROUND The association of different body components, including lean mass and body fat, with the risk of death in acute coronary syndrome (ACS) patients are unclear. METHODS We enrolled adults diagnosed with ACS at our center between January 2011 and December 2012 and obtained follow-up outcomes via telephone questionnaires. We used restricted cubic splines (RCS) with the Cox proportional hazards model to analyze the associations between body mass index (BMI), predicted lean mass index (LMI), predicted body fat percentage (BF), and the value of LMI/BF with 10-year mortality. We also examined the secondary outcome of death during hospitalization. RESULTS During the maximum 10-year follow-up of 1398 patients, 331 deaths (23.6%) occurred, and a U-shaped relationship was found between BMI and death risk (Pnonlinearity = 0.03). After adjusting for age and history of diabetes, the overweight group (24 ≤ BMI < 28 kg/m²) had the lowest mortality (HR = 0.53, 95% CI: 0.29-0.99). Predicted LMI and LMI/BF had an inverse linear relationship with a 10-year death risk (Pnonlinearity = 0.24 and Pnonlinearity = 0.38, respectively), while an increase in BF was associated with increased mortality (Pnonlinearity = 0.64). During hospitalization, 31 deaths (2.2%) were recorded, and the associations of the indicators with in-hospital mortality were consistent with the long-term outcome analyses. CONCLUSION Our study provides new insight into the “obesity paradox” in ACS patients, highlighting the importance of considering body composition heterogeneity. Predicted LMI and BF may serve as useful tools for assessing nutritional status and predicting the prognosis of ACS, based on their linear associations with all-cause mortality.

BACKGROUND: In adults with type 2 diabetes (T2DM), sarcopenia and obesity are two common body composition issues. OBJECTIVE: We investigated the associated influencing factors of muscle mass loss in obese adults with T2DM, to provide a theoretical basis for the prevention of sarcopenic obesity in patients with T2DM. METHODS: We recruited 315 participants in this study. The participants underwent body composition assessment and clinical information was collected. Dual-energy X-ray absorptiometry was used to verify the accuracy of the body composition data. Based on their body fat percentage, 189 patients with T2DM were classified as obese. Patients with T2DM and obesity were grouped into the muscle mass loss group and non-muscle mass loss group based on gender. We collected demographic and clinical information about patients with T2DM who were obese, including their age, gender, body mass index (BMI), appendicular skeletal muscle index (ASMI), and body fat percentage (PBF). RESULTS: Among the participants who were obese and had T2DM, 56.61% (107/189) experienced muscle mass loss, with a detection rate of 43.42% (33/76) among females and 65.49% (74/113) among males. Body mass index, fat index, Android fat, Gynoid fat, limb fat, trunk fat, and total body bone mineral content were all lower in the muscle mass loss group compared to the non-muscle mass loss group, regardless of gender (all P < 0.001). Muscle mass loss in obese adults with T2DM was affected by BMI, body fat index, and limb fat. CONCLUSION: Muscle mass loss is more prevalent in adults with T2DM and a high PBF. Body mass index, body fat index, and limb fat are the protective factors of muscle mass loss in adult patients with T2DM and obesity. [ABSTRACT FROM AUTHOR]

Liaoning cashmere goat (LCG) is one of the excellent cashmere goat breeds in China. Because of its larger size, better cashmere, and better cashmere production performance, people pay special attention to it. This article mainly studied the relationship between SNP loci of LIPE gene and ITGB4 gene and milk production, cashmere production and body measurement traits of LCGs. We further identified potential SNP loci by PCR-Seq polymorphism detection and gene sequence comparison of LIPE and ITGB4 genes. Further, we use SPSS and SHEsis software to analyze their relationship to production performance. The consequence indicated that CC genotype of LIPE gene T16409C locus was dominant genotype in milk production and cashmere production, while CT genotype of LIPE gene T16409C locus was dominant in body size. The CT genotype of C168T locus of ITGB4 gene is the dominant genotype of body type and cashmere production, while the dominant genotype of milk production is TT genotype. Through joint analysis, in haploid combinations, H1H2:CCCT is the dominant haplotype combination in cashmere fineness. H3H4:TTCT is a dominant haplotype combination of milk production traits and body measurement traits. These dominant genotypes can provide a reliable basis for the study of production performance of LCG. [ABSTRACT FROM AUTHOR]

Objective: To evaluate the efficacy of aerobic training, resistance training combined with external diaphragm pacing in patients with chronic obstructive pulmonary disease. Design: Randomized controlled trial. Setting: The Fourth Rehabilitation Hospital of Shanghai, China. Participants: 82 (67.0 ± 6.5 years, 59.8% male) patients with stable chronic obstructive pulmonary disease were randomized to intervention group 1 (n = 27), intervention group 2 (n = 28), and control group (n = 27). Intervention: Intervention group 1 received aerobic and resistance training, while intervention group 2 received additional external diaphragm pacing. Control group received aerobic training only. Main measures: 1-year follow-up of physical activity, body composition, respiratory function and diaphragm function. Results: Intervention groups 1 and 2 showed statistically improvements in the difference value compared with control group in terms of 6-min walk distance (−95.28 ± 20.09 and −101.92 ± 34.91 vs −63.58 ± 23.38), forced expiratory volume in 1 s (−0.042 ± 0.027 and −0.130 ± 0.050 vs −0.005 ± 0.068), fat-free mass (−2.11 ± 3.74 and −3.82 ± 3.74vs 0.28 ± 1.49) and chronic obstructive pulmonary disease assessment test value (2.16 ± 0.85 and 2.38 ± 1.02 vs 1.50 ± 0.93). Intervention group 2 showed significant difference in arterial oxygen pressure (−4.46 ± 3.22 vs −1.92 ± 3.45), diaphragm excursion during deep breaths (−0.82 ± 0.74 vs −0.38 ± 0.29), and diaphragm thickness fraction (−8.77 ± 3.22 vs −4.88 ± 2.69) compared with control group. Conclusion: The combination of aerobic training, resistance training, and external diaphragm pacing obtained significant improvements in physical activity, respiratory function, body composition, arterial oxygen pressure, and diaphragm function in patients with chronic obstructive pulmonary disease.

Objective: To identify the prevalence of obesity, sarcopenia, sarcopenic obesity in end-stage knee osteoarthritis (KOA) patients and analyze influences of obesity and sarcopenia in the progression of KOA. Methods: A cross-sectional study was carried out among end-stage KOA patients who consecutively admitted to Orthopedic Department for TKA. We suppose that the level of decreased physical activities would be influenced by unilateral or bilateral KOA. Patient information, albumin, hemoglobin, pace, step frequency, number of comorbid conditions were collected. Bioelectrical impedance analyzer was used to analyze body composition. Obesity, sarcopenia, sarcopenic obesity rate were analyzed with accepted diagnosis criteria. Correlations between body mass index (BMI) or age and fat mass (FM), appendicular skeletal muscle mass (ASM) were analyzed. Results: 138 patients (male 30, female 108) in southwest of China including 67 patients with unilateral KOA and 71 patients with bilateral KOA were analyzed. No statistic difference was found in mean albumin, prealbumin and hematocrystallin, body composition values and number of comorbid conditions. We found that BMI was positively correlated with FM (Male: R2 = 0.7177, p < 0.0001, Female: R2 = 0.8898, p < 0.0001), ASM (Male: R2 = 0.2640, p = 0.0037, Female: R2 = 0.2102, p < 0.0001), FM index (FMI) (Male: R2 = 0.6778, p < 0.0001, Female: R2 = 0.8801, p < 0.0001), and ASM index (ASMI) (Male: R2 = 0.3600, p = 0.0005, Female: R2 = 0.4208, p < 0.0001) in end-stage KOA patients. However, age was not obviously correlated with FM or FMI (Male: FM, R2 = 0.006911, p = 0.3924; FMI, R2 = 0.7554, p = 0.0009196; Female: FM, R2 = 0.001548, p = 0.8412; FMI, R2 = 0.002776, p = 0.7822). And slightly negatively correlated with ASM (Male: R2 = 0.05613, p = 0.0136, Female: R2 = 0.01327, p = 0.5433) and ASMI (Male: R2 = 0.02982, p = 0.3615; Female: R2 = 0.03696, p = 0.0462). The prevalence of obesity, sarcopenia and obesity sarcopenia differs according to different diagnosis criteria. No difference in the occurrence rate of obesity was found between bilateral KOA and unilateral KOA patients, and occurrence rates of sarcopenia and sarcopenic obesity were statistically higher in bilateral KOA than that in unilateral KOA patients. Conclusions: Obesity, sarcopenia and sarcopenic obesity are highly prevalent in end-stage KOA patients, sarcopenic obesity are more prevalent in bilateral KOA patients than that in unilateral KOA patients.

Increasing daily physical activity (PA) is a practical way to decrease the risk of cardiometabolic diseases, while the studies on exercise intensity remain limited. The purpose of the present study was to compare the effects of increasing light PA (LPA) or moderate-to-vigorous PA (MVPA) for 12 weeks on cardiometabolic markers in Chinese adults with obesity. Fifty-three adults were randomly assigned to the 1) control group, 2) LPA group, and 3) MVPA group in free-living settings. The intervention effects on body composition, cardiorespiratory fitness, and cardiometabolic biomarkers were analysed using a generalized estimated equation model adjusted for baseline values and potential confounders. Compared with the control group, the MVPA group showed improvements in body composition, lipids, C-peptide, monocyte chemoattractant protein-1 (MCP-1), interleukin-8, leptin, and E-selectin. A favourable change in triglycerides and E-selectin were observed in the LPA group when compared to the control group. Lastly, improvements in waist circumference, C-reactive protein, and MCP-1 were observed in the MVPA group when compared to those in the LPA group. Although increasing both LPA and MVPA improved certain cardiometabolic biomarkers, the latter may have more benefits. These findings imply that MVPA may reduce cardiometabolic disease risk more effectively than LPA, especially in Chinese adults with obesity. [ABSTRACT FROM AUTHOR]

Background: Metabolic syndrome (Mets) is considered a global epidemic of the 21st century, predisposing to cardiometabolic diseases. This study aims to describe and compare the body composition profiles between metabolic healthy (MH) and metabolic unhealthy (MU) phenotype in normal and obesity population in China, and to explore the predictive ability of body composition indices to distinguish MU by generating machine learning algorithms. Methods: A cross-sectional study was conducted and the subjects who came to the hospital to receive a health examination were enrolled. Body composition was assessed using bioelectrical impedance analyser. A model generator with a gradient-boosting tree algorithm (LightGBM) combined with the SHapley Additive exPlanations method was adapted to train and interpret the model. Receiver-operating characteristic curves were used to analyze the predictive value. Results: We found the significant difference in body composition parameters between the metabolic healthy normal weight (MHNW), metabolic healthy obesity (MHO), metabolic unhealthy normal weight (MUNW) and metabolic unhealthy obesity (MUO) individuals, especially among the MHNW, MUNW and MUO phenotype. MHNW phenotype had significantly lower whole fat mass (FM), trunk FM and trunk free fat mass (FFM), and had significantly lower visceral fat areas compared to MUNW and MUO phenotype, respectively. The bioimpedance phase angle, waist-hip ratio (WHR) and free fat mass index (FFMI) were found to be remarkably lower in MHNW than in MUNW and MUO groups, and lower in MHO than in MUO group. For predictive analysis, the LightGBM-based model identified 32 status-predicting features for MUNW with MHNW group as the reference, MUO with MHO as the reference and MUO with MHNW as the reference, achieved high discriminative power, with area under the curve (AUC) values of 0.842 [0.658, 1.000] for MUNW vs. MHNW, 0.746 [0.599, 0.893] for MUO vs. MHO and 0.968 [0.968, 1.000] for MUO and MHNW, respectively. A 2-variable model was developed for more practical clinical applications. WHR > 0.92 and FFMI > 18.5 kg/m² predict the increased risk of MU. Conclusion: Body composition measurement and validation of this model could be a valuable approach for the earlymanagement and prevention ofMU, whether in obese or normal population.

This paper analyzed five dragonfly eye beads excavated from M176 of the Hejia Cemetery in the Late Warring States period (around 3rd c. BC) by using a super depth of field 3D microscope system (OM), scanning electron microscope-energy dispersive spectrum (SEM–EDS) and Raman spectroscopy. The analytical results confirmed that all the beads were glazed pottery and the glaze material belongs to the lead-barium-silicate (PbO-BaO-SiO2) system. The color component of the glaze is Chinese Blue (BaCuSi4O10). Three beads, M176-2, M176-3, and M176-4, were formed with an inner core support and were made in the same batch. Additionally, two weathering products, CuPb4(SO4)2(OH)6 and PbCO3, were detected on the glaze layer surface. The results of scientific and technological analysis show that these beads have differences in the composition of the body and glaze, and the color composition in the glaze layer is relatively rare in previous studies. The discovery of lead-barium glazed pottery beads from the Late Warring States period in northern China provides new evidence for further exploration into the origins and evolution of early glazed pottery. The identification of weathering products formed on the beads' surface within an alkaline burial environment holds valuable implications for the study of weathering and deterioration in silicate artifacts.

The aim of this study was to examine the relationship between lean body mass (LBM) and the incidence and severity of neutropenia in patients with malignant tumors from Northern China who have received nanoparticle albumin‐bound paclitaxel. Twenty‐six patients with pathologically confirmed malignant tumors were prospectively included in this study. These 26 patients were divided into Group A (sarcopenia) and Group B (nonsarcopenia). Group A comprised 50% (13/26) of the patients, while Group B comprised the other 50% (13/26). There was no statistically significant difference between both groups in terms of body surface area (P =.052). The incidence of neutropenia in Group A was 76.9% compared to 61.5% in Group B (P =.0673). The incidence of Grade 3 and severe neutropenia was 76.9% versus 61.5% in Groups A and B, respectively (P =.645). These 26 patients were divided into Groups 1 and 2 based on the administered nab‐paclitaxel dose per kilogram of LBM, with both groups receiving a body surface area dose of 260 mg/m2. Group 1 received a nab‐paclitaxel dose of 14.19 mg/kg of LBM, whereas Group 2 received 11.37 mg/kg of LBM. In Group 1, the incidence of neutropenia was 71.4%, whereas it was 66.7% in Group 2. Grade 3 or higher neutropenia incidence was 28.6% in Group 1 versus 16.7% in Group 2. Patients with sarcopenia in northern China experienced a higher incidence of severe neutropenia after receiving nab‐paclitaxel than patients without sarcopenia. Higher drug dose intensity per unit of LBM may be a contributing factor. [ABSTRACT FROM AUTHOR]

Background: We aimed to analyze the characteristics of the body composition of children and adolescents aged 3–17 in Suzhou, China. Methods: A cross-sectional study between January 2020 and June 2022 using bioelectrical impedance was conducted to determine the fat mass (FM), fat-free mass (FFM), skeletal muscle mass, and protein and mineral contents of 24,845 children aged 3–17 who attended the Department of Child and Adolescent Healthcare, Children's Hospital of Soochow University, China. Measurement data was presented in tables as mean ± SD, and groups were compared using the independent samples t-test. Results: FM and fat-free mass increased with age in both boys and girls. The fat-free mass of girls aged 14–15 decreased after reaching a peak, and that of boys in the same age group was higher than that of the girls (p < 0.05). There were no significant differences in FM between boys and girls younger than 9- and 10-years old. The percentage body fat (PBF) and FM index of girls increased rapidly between 11 and 15 years of age (p < 0.05), and those of boys aged 11–14 were significantly lower (p < 0.05), suggesting that the increase in body mass index (BMI) was mainly contributed by muscle mass (MM) in boys. Conclusions: The body composition of children and adolescents varies according to their age and sex. A misdiagnosis of obesity made on the basis of BMI alone can be avoided if BMI is used in combination with FM index, percentage body fat, and other indexes. [ABSTRACT FROM AUTHOR]

This study aimed to assess the relationship between the body composition of children aged 3–5 years and breastfeeding status and duration. The study was conducted using data from the National Nutrition and Health Systematic Survey for children 0–17 years of age in China (CNHSC), a nationwide cross-sectional study. Breastfeeding information and potential confounders were collected using standardized questionnaires administered through face-to-face interviews. The body composition of preschool children was measured using bioelectrical impedance analysis. A multivariate linear regression model was used to assess the relationship between breastfeeding duration and body composition after adjusting for potential confounders. In total, 2,008 participants were included in the study. Of these, 89.2% were ever breastfed and the median duration of breastfeeding was 12 months (IQR 7–15 months). Among children aged 3 years, the height-for-age Z -score (HAZ) for the ever breastfed group was lower than that for never breastfed group (0.12 vs. 0.42, P = 0.043). In addition, the weight-for-age Z -score (WAZ) of the ever breastfed group was lower than that of the never breastfed group (0.31 vs. 0.65, P = 0.026), and the WAZ was lower in children aged 4 years who breastfed between 12 and 23 months than in those who never breastfed. Compared to the formula-fed children, the fat-free mass of breastfed infants was higher for children aged 3 years (12.84 kg vs. 12.52 kg, P = 0.015) and lower for those aged 4 years (14.31 kg vs. 14.64 kg, P = 0.048), but no difference was detected for children aged 5 years (16.40 kg vs. 16.42 kg, P = 0.910) after adjusting for potential confounders. No significant difference was detected in the weight-for-height Z -score (WHZ), body mass index (BMI)-for-age Z -score (BAZ), fat-free mass index, and body fat indicators in the ever breastfed and never breastfed groups and among various breastfeeding duration groups for children aged 3–5 years. No obvious associations were detected between breastfeeding duration, BMI, and fat mass indicators. Future prospective studies should explore the relationship between breastfeeding status and fat-free mass. [ABSTRACT FROM AUTHOR]

The People's Republic of China obtained at the 2020 Tokyo Olympic Games its best historical performance in the triple jump, thereby winning the silver medal. The objective of this case study was to present how evidence-based knowledge was applied to improve selected factors that may have contributed to this result. The factors included running speed, strength, muscle power, jumping technique, body composition, mental preparation, training organization, and recovery. Short training blocks, monitoring of training sessions and athlete's status, individualized tapering, use of activation sessions the day before competition, and postactivation performance enhancement strategies used in training and at the event were concepts followed during the preparation to the Games. Improved performance in field tests and power training was accompanied by positive changes in approach speed, run-up accuracy, and jumping technique, which, together with mental preparation, enabled two personal records to be set in the Olympic final. The results in the field tests were among the best ever reported and could constitute a benchmark for world-class triple jumpers. [ABSTRACT FROM AUTHOR]
