Adolescents' Behaviors, Fitness, and Knowledge Related to Active Living before and during the COVID-19 Pandemic: A Repeated Cross-Sectional Analysis

Knowledge, Attitude, and Practice Toward Pelvic Floor Dysfunction Among Postpartum and Postmenopausal Women: A Cross-sectional Study

INTRODUCTION AND HYPOTHESIS

This research sought to explore the knowledge, attitude, and practice (KAP) toward pelvic floor dysfunction (PFD) among postpartum and postmenopausal women.

METHODS

This cross-sectional study was performed among postpartum and postmenopausal women between May and August 2023. Demographic data, along with KAP scores, were collected using a self-designed questionnaire-based approach.

RESULTS

Six hundred seventy-seven valid questionnaires were collected and analyzed, with 206 (30.43%) participants aged under 30 years old. The mean scores of knowledge, attitude, and practice dimension were 7.1 ± 2.42 (range 0-9), 33.42 ± 4.75 (range 8-40), and 24.69 ± 6.68 (range 7-35). Proactive practice was independently associated with knowledge scores (OR 1.150, 95%CI 1.059-1.249, P = 0.001), attitude scores (OR 1.125, 95%CI 1.081-1.171, P < 0.001), age 30 years or older (OR 2.326, 95%CI 1.555-3.481, P < 0.001), and being in a postpartum state (OR 0.542, 95%CI 0.325-0.903, P = 0.019). The structured equation model revealed that knowledge exerted a strong positive direct effect on attitude (β = 0.634, P < 0.001), attitude had a significant direct effect on practice (β = 0.681, P < 0.001), and knowledge also markedly influenced practice (β = 0.907, P < 0.001).

CONCLUSION

Postpartum and postmenopausal women demonstrated adequate knowledge, positive attitudes, and proactive practices regarding PFD. It emphasizes the significance of tailored education, a holistic approach, and behavioral interventions to improve clinical practice in pelvic floor health.

Effects of school closure on lifestyle behaviours and health outcomes in children during the COVID-19 pandemic in Chile: A time-matched analysis

BACKGROUND

The COVID-19 pandemic led to school closures, potentially impairing children's behaviours and health. We aimed to explore the effects of school closure on lifestyle behaviours (dietary habits, physical activity) and health outcomes (adiposity, fitness, self-esteem, self-concept) in children.

METHODS

We measured 247 children before school closure (October-November 2019) and after school reopening (October-November 2021) (COVID-19 group). To distinguish the changes due to school closure from changes due to growth, we included 655 age-matched children with cross-sectional measurements in October-November 2019 (control group). The response of this group (i.e., differences between children with 2 years of difference) was considered the expected response to growth. Two-way ANOVA was used to test age-by-group interactions, indicating an effect of school closure.

RESULTS

In 7-to-9-year-old children, the COVID-19 group had larger-than-expected decreases in physical activity (by 0.4 points), resulting in higher physical inactivity prevalence (by 19 percent points) at 9 years. This was accompanied by larger-than-expected increases in fat percentage (by 6.1 percent point). In 8-to-10-year-old children, the COVID-19 group had higher physical inactivity prevalence at 10 years (by 20 percent points). This was accompanied by larger-than-expected increases in fat percentage (by 8.3 percent points), z-score BMI (by 0.90 units), and waist circumference (by 6.1 cm). In 9-to-11-year-old children, the COVID-19 group had larger-than-expected decreases in physical activity (by 0.3 points) and increases in self-concept (by 0.2 points). The response in dietary habits, fitness, or self-esteem was not different between groups.

CONCLUSION

Overall, school closure negatively impacted physical activity and adiposity, particularly in the youngest children.

The effects of COVID-19 on the Physical Activity and Recreational Screen Time among Chinese children and adolescents

Background

The lack of Physical Activity (PA) and prolonged Recreational Screen Time (RST) among children and adolescents has been exacerbated during the COVID-19 pandemic, causing this issue to escalate into a crucial public health concern. This study aims to investigate the trends in PA and RST among Chinese children and adolescents from 2019 to 2022, thereby analyzing the short-term and long-term effects of the pandemic on PA and RST among Chinese children and adolescents.

Methods

A nationally representative sample of Chinese primary, middle, and high school students was surveyed annually between September and December from 2019 to 2022 using a consistent set of questionnaires. Trends in PA and RST across different school levels, genders, areas (urban/rural), and regions (north/south) were analyzed using Segmented Linear Regression.

Results

From 2019 to 2022, the PA and RST of children and adolescents displayed an inverted U-shaped trend, initially increasing and subsequently declining. Specifically, from 2019 to 2021, the PA of children and adolescents significantly increased but dramatically declined from 2021 to 2022. This trend in PA is more pronounced among primary, male, urban, and northern children and adolescent. The RST of children and adolescents increased from 2019 to 2020 but significantly decreased from 2020 to 2022. This trend in RST is more pronounced among primary, urban, and southern children and adolescent.

Conclusions

This research unveils the effects of the pandemic on PA and RST in children and adolescents, suggesting short-term beneficial and long-term adverse effects on PA and short-term adverse and long-term beneficial effects on RST. These findings provide a foundation for formulating policies related to children and adolescents' PA and RST during the pandemic.

How to Reduce Physical Inactivity in School Context? A Systematic Review of the Concept of Body Practices

(1) Background: Physical inactivity is a recognized global problem, with schools identified by UNESCO and WHO as critical settings for intervention. Despite existing efforts, the prevalence of physical inactivity remains high. This study aims to explore the potential of the concept of body practices as a novel framework to address physical inactivity within school contexts, potentially offering an alternative to traditional intervention models. (2) Methods: This study carried out a systematic review of the concept of body practices to understand its use in the scientific literature. (3) Results: The results indicate that (a) the definition of the concept that the authors used is broad; (b) the problems they face are varied, such as the life cycle, negative emotions, gender, physical inactivity, well-being, and social problems; (c) the research methodologies are predominantly quantitative; (d) and the intervention in schools focuses on students, but not on the entire school community. (4) Conclusions: this concept has great potential for use in initiatives and/or policies that seek to address physical inactivity in the school context.

Temporal Changes in Energy-Balance Behaviors and Home Factors in Adolescents with Normal Weight and Those with Overweight or Obesity

This study aimed to examine the temporal changes in energy-balance behaviors and home factors in adolescents with normal weight and those with overweight or obesity (OWOB). Adolescents or parent proxies completed survey assessments two to four years before (T0; n = 82 ), ≤ six months before (T1; n = 68 ), and ≤ three months after the COVID-19 pandemic outbreak (T2; n = 82 ), to capture energy-balance behaviors (i.e., physical activity [PA], screen time, sleep) and home factors (i.e., food environment, food worry, parent support for PA). At T0 and T1 (before pandemic), participants visited our laboratory for anthropometric measurements. At T2, parent proxies also completed a survey to report the COVID-19 pandemic exposure and impact. The participating families experienced moderate levels of pandemic exposure and impact, although exposure was higher in the OWOB group F 1,78 = 5.50 , p < . 05 . Repeated-measure multivariate analyses of covariance (RM-MACOVAs) did not show significant time by weight status interaction effects (p > 0.05 ; adjusted for race and sex). However, the models detected significant time (T0 vs. T2) by race (White vs. non-White) interaction effect λ 7,66 = 0.81 , p < 0.05 , with greater increase in food worry F 1,72 = 4.36 , p < . 05 but less increase in screen time F 1,72 = 4.54 , p < . 05 among the non-White group. Graphical visualization depicted some favorable change patterns in adolescents with normal weight (vs. those with OWOB) for certain behaviors and home factors (e.g., number of days per week ≥ 60 mins PA, food worry). These findings suggest that the COVID-19 pandemic exerted greater adverse effects on adolescents with OWOB and specifically on screen time and food worry among non-White adolescents.

How Can Physical Inactivity in Girls Be Explained? A Socioecological Study in Public, Subsidized, and Private Schools

In the last few years, the World Health Organization has highlighted that physical inactivity is a global issue affecting women to a greater extent than men. Faced with this, different nation states have developed public policies to reduce physical inactivity at school; however, the biomedical and individualistic models used have generated widespread criticism, as figures remain the same. In the context of failed interventions on increasing levels of physical activity, this study utilizes a socioecological model to analyze and understand how physical inactivity is reproduced in girls in the Chilean education system. A qualitative study was implemented, as it allows a focus on the entailed meanings, context, and processes. Active semi-structured interviews were conducted with 40 groups comprising headmasters, teachers, non-teachers, students, and families. The results show that physical inactivity is linked to factors that go beyond the individualistic model; that is, consideration must include intrapersonal, interpersonal, organizational, community, and public policy dimensions. Furthermore, gender stereotypes gain relevance in physical education classes, in addition to friendships and family, teaching, and administrative work, access to safe play areas, use of spaces, and widespread cultural factors associated with men and women. This study concludes that the assessed gender differences should be approached from a pedagogical perspective beyond common sense, further reporting that the individualized explanation for physical inactivity is irrelevant to answer why women are more inactive than men.

Change in physical fitness due to the COVID-19 pandemic lockdown in French adolescents: a comparison between two independent large samples from Diagnoform battery

Numerous studies reported a significant decline in physical activity level in adolescents as a result of the COVID-19 lockdown. Physical fitness is recognized as a powerful marker of health in youth. The aim of this study was to evaluate the impact of the COVID-19 pandemic lockdown on health-related physical fitness in French adolescents. Two cross-sectional studies were performed comparing two different groups of French adolescents, before (sample 1) and after the first lockdown (sample 2). A total of 1231 adolescents (aged to 16.5 ± 1.5 years) participated in the two cross-sectional studies. Complete data for physical fitness and anthropometrics data were obtained. Adolescents from sample 2 showed lower physical fitness levels compared to adolescents from sample 1. Regarding physical fitness for boys and girls, physical fitness levels were significantly lower in both sex between adolescents from the sample 1 and adolescents from the sample 2, except for cardiorespiratory fitness and flexibility for boys and girls, respectively. The physical fitness global score was also significantly lower between adolescents from the sample 1 and 2 for boys (-9.8%, p < 0.01) and girls (-16.2%; p < 0.01), respectively. Overall, the higher difference was found for performance in the speed body displacement test (-30%). A difference of 12.8% and 25% was observed for boys and girls, respectively.   Conclusion: COVID-19 pandemic lockdown had a negative impact on physical fitness in French youth. This study highlights the need to develop, in a near future, prevention programmes in order to improve the physical fitness in youth. What is Known: • COVID-19 pandemic deeply impacted lifestyle habits. A worrying decrease of physical activity, associated to a dramatic increase of time spent in sedentary behaviors was found in many coutries. What is New: • Our study bring first data on the health-related physical fitness consequences due to lockdown in French adolescents. Our study demonstrate the negative impact of COVID-19 pandemic lockdown on health-related physical fitness in French adolescents.
