The negative association between the growth mindset and mental health problems suggests that prevention and intervention programs to improve mental health by targeting mindset may have potential clinical value. However, research on the longitudinal effect of mindset on adolescent mental health and its underlying mechanisms is lacking. Using a three-wave longitudinal design, we obtained data from a diverse sample of Chinese adolescents (n = 2543). Longitudinal multiple mediation models were constructed to examine the effects of the growth mindset on levels of anxiety and depression two years later. In addition, the mediating effects of smartphone use for entertainment and problematic smartphone use (PSU) were examined. After controlling for various covariates and the autoregressive effects of mental health problems, the growth mindset had significant negative effects on anxiety (β = -0.053, p = 0.004) and depression (β = -0.074, p < 0.001). Smartphone use had a significant mediating role in the effect of mindset on anxiety (β = -0.016, p < 0.001) and depression (β = -0.016, p < 0.001). The growth mindset has long-lasting positive effects on adolescent mental health. Smartphone use for entertainment and PSU mediate the effect of mindset on adolescent mental health.Health guidelines suggest that caregivers provide preschoolers with opportunities to be physically active for 3 h per day (roughly 15 min per waking hour), but because children are not continuously active, it is unclear what amount of time is needed to reach this goal. This naturalistic study enrolled 67 children (M = 4.5 years, 46% female) who wore accelerometers to measure their activity during indoor and outdoor free -play (N = 315,061 s). An hour of indoor play was insufficient for most children to reach 15 min of physical activity. When outside, most children reached 15 min of physical activity after slightly more than 30 min. Children engaged in outdoor activity sporadically (1.7 starts/stops per minute). Most physical activity occurred in bouts shorter than 20 s. Indoor free-play does not, on its own, provide sufficient opportunity for preschoolers to engage in physical activity consistent with health guidelines. As a result, outdoor play for at least 30 min at a time has a key role in meeting these guidelines.Sport participation provides a direct means to attain health-enhancing physical activity; however, sport participation declines during adolescence, and over 85% of adolescent females fail to meet the recommended 60 min of moderate-vigorous physical activity daily. Given the importance of overcoming barriers to sport and increasing equity in women's sports, the purpose of this systematic review was to identify factors associated with sport participation among adolescent girls and operationalize those factors into theoretical constructs to guide future research. Six databases were systematically searched, and 36 records were included for review. Factors impacting girls' sport participation were categorized as personal, peer, family, socioeconomic, environmental, or other factors. Of these categories, personal factors, including self perceptions and desirable personal outcomes related to sport, were most frequently associated with sport participation. Most research on girls' sport participation lacks theoretical framework, so to aid future studies, this review categorized important participatory factors into the constructs of the theory of planned behavior. Future research would benefit from theory-driven prospective approaches to make clear and consistent predictions about factors impacting sport participation, as well as mixed-method approaches aimed to provide more robust understanding of girls' experiences with and perceptions of factors impacting their participation in sports.
The COVID-19 pandemic has brought a new threat to child health and safety. Some studies suggest that social isolation and economic stress have exacerbated child abuse and neglect, whereas other studies argue that orders to stay at home are likely to promote parent-child relationships during this stressful time. Due to a lack of prospective studies including before-during-after lockdown assessments, the impacts of lockdown measures on child maltreatment are unclear.
This study retrospectively investigated child maltreatment of 2821 Chinese children and adolescents from 12 to 18 (female, 59%) before, during and after lockdown, and identified risk factors. Potential predictors including socio-economic and individual mental health status were collected.
During Chinese lockdown, children and adolescents reported that the proportions of decrease (range 18-47.5%) in emotional abuse and neglect, physical abuse and neglect, sexual abuse, and witnessing domestic violence were greater than that of increase (range 5.1-9.1%). Compared with before lockdown (1.6%), the prevalence of sexual abuse significantly increased 8 months (2.9%) after the lifting of lockdown (
= 0.002). Being male, suffering from depression, state anhedonia, and experiencing psychotic symptoms at baseline were associated with increased sexual abuse after lockdown.
The impact of lockdown on child maltreatment was beneficial in the short-term but detrimental in the long-term in China.

Males (n = 11) and females (n = 11) were strength-matched via isometric mid-thigh pull testing, whereby peak force values were normalised to body mass. Subjects performed three maximal-effort countermovement jumps (CMJs) on a force platform from which a range of kinetic and kinematic variables were calculated via forward dynamics. Thereafter, differences in gross measures were examined via independent t-tests, while differences in force-, power-, velocity-, and displacement-time curves throughout the entire CMJ were analysed using statistical parametric mapping (SPM). Jump height, reactive strength index modified, propulsion mean force, propulsion impulse, and propulsion mean velocity were all greater for males (d = 1.50 to 3.07). Relative force- and velocity-time curves were greater for males at 86-93% (latter half of the concentric phase) and 85-100% (latter half of the concentric phase) of normalized movement time, respectively. Time to take-off, braking phase time, braking mean velocity and impulse, propulsion phase time and centre of mass displacement were similar between males and females (d = -0.23 to 0.97). This research demonstrates the strength of SPM to identify changes between entire force-time curves. Continued development and the use of SPM analysis could present the opportunity for a refined comparison of strength-matched male and female CMJ performance with the analysis of entire force-time curves.Metabolic syndrome (MetS) is a disease with a high prevalence that threatens the health of modern people. Patient education is essential to control MetS. This prospective study aimed to evaluate 6-month changes in health indicators following a two-day education program for patients with MetS aged 45 or older. Education about MetS, lifestyle modification, nutrition, and physical activity was provided. At 3 and 6 months after the program, participants visited for follow-up. Twenty-two patients completed the 6-month study. Waist circumference was reduced, and life quality and depression index improved in 3 and 6 months compared to pre-education. Blood pressure decreased, and anxiety index improved at three months. Nutritional knowledge was well maintained for 3 and 6 months. High-density lipoprotein-cholesterol levels increased at six months. Three out of twenty-two patients did not satisfy MetS criteria at the end of the study due to improved indicators. A two-day multidisciplinary education program positively affected health indicators in MetS patients. Participation in the program also help with life satisfaction and positive emotional condition. However, some indicators improved in 3 months, but the effect disappeared 6 months after the program.
The outbreak of the COVID-19 pandemic affected many aspects of life involving sexual functioning.
This prospective, noninterventional, observational research was performed from July 2020 to August 2020, involving a total of 644 patients. Female sexual function index (FSFI) scores of those women were compared in relation to results of our research from April 2020. Questionnaires were collected concerning socio-demographic characteristics of patients as well as the impact of the COVID-19 pandemic on their lives.
Every domain significantly decreased in the first month of the lockdown. Before the pandemic, the total FSFI was reported at 30.1 ± 4.4, while in the first month of the pandemic it was at 25.8 ± 9.7 (
< 0.001). The lowest FSFI score was reported by women who lived in average conditions. There was a statistically significant increase in the overall FSFI score in the fifth month of the pandemic (27.5 ± 6.8) when compared to the FSFI score in the first month of the pandemic (25.8 ± 9.7). The scores in arousal, lubrication, orgasm and pain were reported as higher (respectively
< 0.001,
< 0.001,
< 0.001,
< 0.05), while desire was reported lower (
< 0.001). The satisfaction score remained almost the same (
< 0.05).
Our study indicates a significant decrease in FSFI scores across all domains. There are still many questions whether the statue from the vaccinated person or convalescents affects the sense of security and, thus, increases sexual satisfaction.

With a cross-sectional design, this study investigated two possible mediating factors in the relationship between hope and depression among Chinese shadow education tutors, who confront a high turnover rate and are at high risk for depression. Altogether, 221 tutors participated in the survey, and reported their dispositional hope, perceived social support (PSS), perceived stress (PS), and depression. Results indicated that both PSS and PS mediated the relationship between hope and depression. Results also supported the hypothesized serial mediating effect. check details In other words, hope as a positive disposition may promote PSS, which can mitigate PS. The reduced PS, in turn, alleviates depression. This finding not only shed light on the independent and accumulative mediating effects of PSS and PS, but also has implications for preventive interventions among Chinese shadow education tutors experiencing the enormous pressure of instability. This serial mediation model should be confirmed by further longitudinal study.The objective of this scoping review is to determine to what extent the recommendations on perinatal care protect breastfeeding during the COVID-19 pandemic. The review follows the PRISMA ScR Extension guidelines. The research was conducted in Scopus, Medline via Pubmed, and Web of Science databases from 1 March 2020 to 31 May 2021, using 392 combinations of keywords. We searched for reviews and original papers published in English providing recommendations on delivery mode, companion during labor, the possibility of skin-to-skin contact (SSC), breastfeeding, and visitors policy. After screening, 86 out of 8416 publications qualified for data extraction. The majority of them indicated that COVID-19 infection is not a sufficient reason for a cesarean section; however, on a national level, cesarean births in severely ill patients were overrepresented. A significant number of recommendations deprived mothers of the necessary support during their labor and stay in the maternity ward. A shared decision-making model was hardly visible.
