Poor nutrition or insufficient physical activity (PA) are risk factors for obesity and chronic diseases. This 2019 cross-sectional study from the school health survey examined the dietary and PA behaviors of Chinese adolescents. A total of 12,860 adolescents aged 11–18 participated through multistage and stratified cluster random sampling. A questionnaire collected data on weight, PA, sedentary lifestyle, and eating habits. Unhealthy behaviors were identified and summed up for each behavior. Participants were then classified into high and low amounts of risk behaviors. Weight status was defined using Body Mass Index (BMI) cutoff points for Chinese individuals aged 6–18. Multinomial logistic regression was used to assess effects of lifestyle behaviors on weight status. The prevalence of overweight and obesity was 22.3% among all participants (30.6% in boys, 13.2% in girls). Females engaged in more risk physical activities (4.12 vs. 3.80, p < 0.05), while males engaged in more risk dietary activities (2.20 vs. 2.02, p < 0.05). Higher number of risk dietary, PA, and sedentary behaviors were all significantly correlated with higher BMI (dietary: r = 0.064; PA: r = 0.099; sedentary: r = 0.161; p < 0.001 for all) and body weight (dietary: r = 0.124; PA: r = 0.128; sedentary: r = 0.222; p < 0.001 for all). Risk sedentary behaviors was a significant risk factor for overweight/obesity (Adjusted Odds Ratio AOR = 1.30, 95% Confidence Interval CI 1.11–1.52). Obesity and unhealthy lifestyle behaviors remain a concern among Chinese adolescents. These results provide an update on the factors contributing to overweight/obesity among adolescents and call for efforts to address obesity among adolescents.

Epidemiological Characteristics

ObjectivesThis study aimed to investigate the epidemiological characteristics and preliminarily explore possible risk factors of physical activity-related injury (PARI) occurrences among Chinese university students via a multicentre mixed survey.DesignCross-sectional study.ParticipantsA total of 4758 undergraduates graded 1–3 in nine universities in three Chinese cities were enrolled via cluster random sampling and completed the self-administered online questionnaires during March and April 2017.Main outcome measuresPARI in the past 12 months.ResultsOf the 4758 participants, 1081 sustained PARI in the past 12 months, with an overall PARI incidence rate of 22.7% (27.3% (367/1343) in males and 20.9%(714/3415) in females). Around one-quarter of the injured (26.4%) suffered from PARI over at least three episodes. More than half of the injured subjects experienced physical activity (PA) absenteeism and sought medical attention. All PA indicators were significantly and positively associated with PARI, with a frequency of sports and leisure-time vigorous-intensity PA (VPA) participation being the strongest (adjusted OR: 1.079, 95% CI: 1.018 to 1.144). Moreover, males (OR=1.199), Shantou students (OR=4.239), year 1 students (OR=1.287), university and other sports team members (OR=1.717–2.360) and those with insufficient sleep time (OR=1.262–1.333) were also at a higher risk of PARI.ConclusionsPARI is prevalent among university students in China. The frequency of sports and leisure-time VPA participation was most strongly associated with PARI among all PA indicators. These data can inform future programmes for injury intervention among university students. Safety issues should also be emphasised when promoting PA among the public to reduce PARI.

Abstract Objectives Evidence that sedentary behaviors were correlated with unhealthy diet and physical activity were mostly among children and adolescents, but still limited for adults. The aim of this study was to examine the associations between screen-based leisure-time sedentary behaviors (LTSB) including television time and computer time with unhealthy dietary behaviors, and leisure-time physical activity (LTPA) among Chinese adults. Methods Participants (n = 10,108, aged 18–59 years) from a recent cross-sectional study of CHNS (China Health and Nutrition Survey) conducted in 2015 were analyzed. Time spent in LTSB and LTPA were collected from questionnaire. Unhealthy dietary behaviors were collected from three consecutive 24-hour food recalls and the food frequency method. Multivariable logistic regression models were produced to study the odds ratios for unhealthy dietary behaviors and LTPA as the function of the quintile of LTSB. Results Versus the lowest quartile, the OR(95%CI) of the highest quintile of computer time for insufficient vegetable intake (&lt; 300 g/d) was 1.4(1.0,2.0) for male and 1.5(1.1,2.2) for female; the OR(95%CI) for excessive snack intake (≥1 time/day) was 1.6(1.0,2.3) for male and 1.7(1.3,2.4) for female; the OR(95%CI) for excessive western fast food intake (≥1 time/week) was 2.4(1.2,4.4) for male and 2.7(1.4,4.9) for female. The OR(95%CI) of the highest quintile of television time for no LTPA group (0 Mets.h/w) was 1.8(1.3,2.6) for male and 1.5(1.1,2.0) for female; the OR(95%CI) for sufficient LTPA group (≥8 Mets.h/w) was 0.5(0.4,0.8) for male and 0.7(0.5,0.9) for female. The OR(95%CI) of the highest quintile of computer time for no LTPA group (0 Mets.h/w) was 0.4(0.3,0.6) for male and 0.5(0.4,0.7) for female; the OR(95%CI) for sufficient LTPA (≥8 Mets.h/w) group was 2.4(1.7,3.3) for male and was 2.1(1.5,2.9) for female. Conclusions LTSB were associated with unhealthy dietary behaviors and mixed LTPA among Chinese adults. The patterns of “Television time-less LTPA” and “Computer time-unhealthy diet-more LTPA” for Chinese adults were principal associations. Our findings suggest the need for different behavior preventive intervention on different types of screen-based LTSB among Chinese adults. Funding Sources The survey received funding from NIH and from Ministry of Finance of the People's Republic of China.

Introduction: Less is known about the effects of the different domains of sedentary behaviors on healthy weight in young children. This cross-sectional study examined the association between sedentary screen time (SST), non-screen-based sedentary time (NSST), and overweight (and obesity) in Chinese preschoolers.Methods: Data were collected from the Physical Activity and Health in Tianjin Chinese Children study (PATH-CC), involving healthy children 3–6 years old and their families. Children's overweight status was classified according to the international (IOTF) childhood BMI cut-offs. SST and NSST were reported in minutes/day by parents using the leisure-time sedentary behaviors questionnaire. Logistic regression models adjusted by sex, age, socioeconomic status, outdoor play, and sleep duration were used.Results: In a total of 971 children (55.4% boys), 11.8% were overweight. Generally, children spent 1 h/day in SST and 1 h/day in NSST. Multiple models showed that children who spent more time in SST were more likely to be overweight [OR and 95% CI: 1.22 (1.03–1.45)]. No correlation between time spent on NSST and children with overweight was found (P &gt; 0.05).Conclusions: This study indicated that children who spent more time in SST were more likely to be overweight, but a null correlation between NSST and overweight was found. Longitudinal studies designed to identify associations between exposures to screen media and changes in metabolic parameters during a child's early years are needed.

The Mean

This report on overweight is based on a cross-sectional study in Skaraborg County, Sweden, in 1977. Mean values of Body Mass Index (BMI) are higher in this county than in other areas studied in Sweden and abroad. In correlation analysis the strongest association was found between overweight and hypertension. This is of particular interest since other studies have shown that Skaraborg county, has one of Sweden's highest proportions of treated hypertensives and also higher mortality during the 1970s in hypertension and obesity related diseases. The BMI varied between the municipalities of the county. Overweight was most common in the agricultural municipalities. The mean value of the BMI was higher among workers and persons with less formal education. This is contradictory to earlier Swedish studies with regard to men but not women. Physically demanding jobs accounted for more overweight individuals whereas high physical activity during leisure time was correlated with low body weight.
