Kim J, Hwang IW, Park JH, Kim Y, Lee JM. Effects of COVID-19 outbreak on Korean adolescents: Impact of altered economic perception on physical activity, sedentary behavior, and stress levels in an age-, gender-, and BMI-matched study. PLoS One 2023; 18:e0294270. [PMID: 37956137 PMCID: PMC10642811 DOI: 10.1371/journal.pone.0294270] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2023] [Accepted: 10/27/2023] [Indexed: 11/15/2023] Open
Abstract
The current study is to examine the disparities in physical activity (PA), sedentary behavior (SB), and stress levels in Korean adolescents concerning changes in their perception of family economic status (ES) during COVID-19. Among a total of 6144 Korean adolescents aged 12 to 18, the participants were categorized into two groups based on their responses regarding changes in their family ES due to COVID-19: Declined ES (n = 3072) and Non-changed ES (n = 3072), with matching in terms of age, gender, and BMI. All variables were assessed using the 16th year (2020) of the Korean Youth Risk Behavior Survey. Statistical analyses were conducted using the SPSS 26.0 version, employing independent t-tests to examine anthropometrics' differences and multinominal logistic regression to predict the impact of perception of family ES on PA, SB, and stress while comparing the two groups. The significance level was set at α = 0.05. Adolescents in the Declined ES group were 1.2 times more likely to engage in MVPA for less than 420 mins/wk (OR = 1.16, p = 0.039), 1.7 times more likely to meet recommended muscular strength activities (i.e., ≥ 3 days/wk) (OR = 1.70, p < 0.001), 37% less likely to not meet recommended recreational sitting time (i.e., ≥ 840 mins/wk) (OR = 0.63, p < 0.01), and were 2.1 times more likely to experience very severe stress level than the Non-changed ES group (p < 0.001). These results shed light on the importance of promoting mental health care in adolescents, regardless of PA levels, for their well-being during potential future pandemics. Understanding the impact of perceived ES changes on health behaviors can inform targeted interventions and support strategies to improve the mental health outcomes of adolescents during challenging times.

Abstract
Exercise is one of the most commonly reported symptom triggers for people with asthma. However, a growing body of evidence indicates that regular exercise and physical activity are associated with improved clinical and patient reported outcomes. In this article, we summarise and consolidate recent original studies evaluating exercise and physical activity profiles in people with asthma and provide an up-to-date perspective concerning the role of exercise training and physical activity promotion in the context of asthma management. To conclude, we identify key unmet needs and provide directions for future research.

Mol Med Rep 2022; 25:74. [PMID: 35014685 PMCID: PMC8778652 DOI: 10.3892/mmr.2022.12590] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2021] [Accepted: 12/20/2021] [Indexed: 11/16/2022] Open
Abstract
Dexmedetomidine (DEX) suppresses inflammatory responses and protects against organ injury. The aim of the present study was to investigate the effect of DEX on airway hyperresponsiveness (AHR) and allergic airway inflammation, as well as its underlying mechanism of action in a murine model of ovalbumin (OVA)-induced asthma. A total of 30 female BALB/c mice were divided into 6 groups (n=5 mice/group): Control, OVA, OVA + DEX (20, 30 or 50 µg/kg) and OVA + TAK-242 [a toll-like receptor 4 (TLR4) inhibitor]. The mice were intraperitoneally injected with 20, 30 or 50 µg/kg DEX 1 h before OVA challenge. AHR to inhaled methacholine (Mch) was measured, and the mice were sacrificed 24 h after the last challenge. AHR following Mch inhalation was measured using the FlexiVent apparatus. Hematoxylin and eosin, periodic acid-Schiff and Wright-Giemsa staining was performed to evaluate inflammatory cell infiltration in the lung tissue. The levels of IL-4, IL-5 and IL-13 in the bronchoalveolar lavage fluid were analyzed using ELISA, and their mRNA expression levels in the lung tissue were examined using reverse transcription-quantitative PCR. The protein expression of TLR4, NF-κB and phosphorylated (p)NF-κB in the lung tissue was also detected using immunohistochemistry. In the murine OVA-induced asthma model, DEX decreased AHR following Mch inhalation and reduced the infiltration of inflammatory cells. IL-4, IL-5 and IL-13 levels in the bronchoalveolar lavage fluid were significantly lower following DEX treatment. Furthermore, DEX treatment inhibited the expression of TLR4, NF-κB and p-NF-κB in the lung tissue and exhibited a similar effect to TAK-242 treatment. In conclusion, DEX may attenuate AHR and allergic airway inflammation by inhibiting the TLR4/NF-κB pathway. These results suggested that DEX may represent a potential anti-inflammatory agent for the treatment and management of patients with asthma.
