In this narrative review, we summarized evidence from peer-reviewed articles, published before February 2024, that investigated lifestyle behaviors among children (≤12 years) and adolescents (13-18 years) representing different geographic descents. These behaviors included dietary patterns, screen time, physical activity, smoking, alcohol consumption, oral hygiene, unsafe sex, and sleep duration and quality. We documented the significant impacts of parental, school, and sociodemographic factors on the adoption of numerous lifestyle behaviors in this age category. Several health consequences could be attributed to unhealthy lifestyle behaviors during childhood and adolescence. For example, poor dietary habits can lead to a higher risk of obesity and cardiovascular disease. Physical inactivity contributes to the development of musculoskeletal and psychological disorders. Excessive screen time is associated with visual acuity problems, poor sleep, and psychological and behavioral problems. Tobacco use poses a significant risk for severe respiratory and cardiovascular diseases. Risky sexual behaviors are related to sexually transmitted infections and exposure to violence. Short sleep duration is associated with a lack of physical fitness and poor cognitive function. However, potential interventions, such as school-based health programs, community outreach initiatives, and national health policies and regulations, can improve lifestyle behaviors among children and adolescents.

Objective: To investigate the association between intrahepatic cholestasis of pregnancy (ICP) and the risk of gestational diabetes mellitus (GDM) and preeclampsia via meta-analysis. Methods: Pooled odds ratio (OR) and confidence interval (CI) of GDM and preeclampsia for women with ICP were calculated using the fixed- or random-effects model. Results: Women with ICP were more likely to have GDM (pooled OR = 2.19, 95% CI: 1.58, 3.03, I² = 88.25%) and preeclampsia (pooled OR = 2.58, 95% CI: 2.37, 2.81, I² = 0%) than women without ICP. Conclusion: The present study supports the concept that ICP is associated with the risk of GDM and preeclampsia.

Aims The enormous spread of the Novel Corona Virus Disease (COVID-19) represents a challenge to dermatological practice. Accumulating evidence has suggested a possible role of teledermatology in facing this challenge. In this article, we aimed to give a general overview of teledermatology in terms of models of practice, modes of delivery, advantages, limitations, ethical considerations, and legislative challenges as well as discussing, using examples from literature, how dermatological practice can benefit from teledermatology during the time of the COVID-19 pandemic. Discussion and conclusion Teledermatology could be an accessible, accurate, and cost-effective substitute for conventional face-to-face dermatological consultations during the COVID-19 pandemic. However, teledermatology practice needs updated legislation and guidelines. More efforts should be done to encourage dermatologists, especially in underserved communities, to provide teledermatology services. Ethical issues and data security related to teledermatology have to be considered.
