Global prevalence of digital addiction in general population: A systematic review and meta-analysis.

The present meta-analytic review aimed to synthesize the global prevalence characteristics of digital addiction in the general population. We searched PubMed, Embase, Cochrane Library, and PsycINFO for studies reporting prevalence of various subtypes of digital addiction published before October 31, 2021. Studies were eligible if they were published in peer-reviewed journals, used a validated tool to assess digital addiction, and passed the qualify assessment. In total, 498 articles with 507 studies were included in systematic review, and the meta-analysis included 495 articles with 504 studies covering 2,123,762 individuals from 64 countries. Global pooled prevalence estimates were 26.99% (95% CI, 22.73-31.73) for smartphone addiction, 17.42% (95% CI, 12.42-23.89) for social media addiction, 14.22% (95% CI, 12.90-15.65) for Internet addiction, 8.23% (95% CI, 5.75-11.66) for cybersex addiction, and 6.04% (95% CI, 4.80-7.57) for game addiction. Higher prevalence of digital addiction was found in Eastern Mediterranean region and low/lower-middle income countries. Males had higher risk for Internet and game addiction. An increasing trend of digital addiction during the past two decades was found, which dramatically worsened during COVID-19 pandemic. This study provides the first and comprehensive estimation for the global prevalence of multiple subtypes of digital addiction, which varied between regions, economic levels, time periods of publication, genders, and assessment scales.

Internet Addiction Increases in the General Population During COVID-19: Evidence From China.

BACKGROUND AND OBJECTIVES: COVID-19-related quarantine and stress have likely escalated the crisis of Internet addiction. This study aimed to determine the impact of the COVID-19 pandemic on Internet use and related risk factors among the general public in China. METHODS: A large-sample cross-sectional online survey was conducted from March 24 to April 30, 2020, in China, and 20,472 participants completed the survey. We investigated the prevalence and severity of Internet addiction based on the Internet Addiction Test (IAT), and explored the risk factors related to increases in time spent on Internet use and severity of Internet addiction, as well as severe Internet addiction. RESULTS: The overall prevalence of Internet addiction was 36.7% among the general population during the pandemic, and that of severe Internet addiction was 2.8%, according to IAT scores. Time spent on recreational Internet use had significantly increased during the pandemic, and almost half of participants reported increases in the severity of Internet addiction. Risk factors for increases in time spent on Internet use and severity of Internet addiction and severe Internet addiction included having fewer social supporters, perceiving pressure and impact on mental health status due to COVID-19, and being over-engaged in playing videogames. DISCUSSION AND CONCLUSIONS: The COVID-19 pandemic adversely impacted Internet use and increased the prevalence and severity of Internet addiction among the general population in China, especially in vulnerable populations. SCIENTIFIC SIGNIFICANCE: This study provides evidence for policymakers to refine public health policies to control the pandemic and make efforts to provide population-specific prevention and interventions for people at risk of developing Internet addiction.

Clinical features of neonatal listeriosis in Taiwan: A hospital-based study.

BACKGROUND: Neonatal listeriosis is a major cause of mortality in newborn; however, there is limited information about this disease in Taiwan. The aim of our study was to identify the outcome determinants, clinical features, and incidence of pregnancy-associated listeriosis, which includes both neonatal and maternal listeriosis. METHODS: We retrospectively analyzed the medical records of neonatal and maternal patients with pregnancy-associated listeriosis at two hospitals in Taiwan from January 2000 to December 2018. Listeriosis was indicated by positive Listeria monocytogenes culture. RESULTS: Our study examined 18 neonates and 19 mothers. The neonatal and fetal death rate was 24%. All five cases of fetal losses or neonatal deaths occurred before 29 weeks of gestational age. The annual incidence of confirmed neonatal listeriosis increased significantly from 0.94/10,000 neonatal inpatients in 2000-2011 to 5.45/10,000 neonatal inpatients in 2012-2018 (p = 0.026). Clinical presentations of neonatal listeriosis included respiratory distress (85%), leukocytosis or leukopenia (77%), bandemia (69%), thrombocytopenia (77%), hypocalcemia (100%) and elevated C-reactive protein (CRP) levels (92%). Lower gestation correlated with a higher fatality rate (p = 0.002). Among the maternal cases investigated, 67% had a diagnosis of listeriosis, and 72% presented with fever. However, only 21% of the 19 mothers received complete antepartum ampicillin treatment. CONCLUSIONS: The incidence of neonatal listeriosis is increasing, especially in preterm neonates. Maternal listeriosis should be adequately treated with appropriate empirical antibiotics.

Risk factor analysis and molecular epidemiology of respiratory adenovirus infections among children in northern Taiwan, 2009-2013.

BACKGROUND/PURPOSE: Respiratory infections caused by human adenoviruses (HAdV) are worldwide, and have significantly increased recently in Taiwan. This study aimed to clarify the molecular epidemiology and risk factors of HAdV severe infections and pneumonia among Taiwanese children. METHODS: Patients with HAdV infections and hospitalized in a medical center between 2009 and 2013 were divided into severe or nonsevere HAdV infections based on whether or not they received intensive care. HAdV pneumonia was identified for comparison. The HAdV genotype was determined by sequencing the partial hexon and fiber genes. The nucleotide sequences were compared by phylogenetic analysis. RESULTS: The 176 patients (97 boys, 79 girls) had a median age of 3.7 years. The HAdV infections circulated year-round. HAdV B3 (54.5%) was the most common genotype, followed by HAdV C2 (21%), HAdV E4 (8%), and HAdV B7 (6.8%). Thirty-two patients needed intensive care. In multivariate analysis, the risk factors for severe HAdV infections were underlying neurologic diseases [odds ratio (OR): 164.9; p < 0.001], prematurity (OR: 10.9; p = 0.042), and HAdV B7 (OR: 39.5; p = 0.011). Twenty-nine patients had HAdV pneumonia. Patients with underlying neurologic diseases (OR 76.8; p < 0.001), airway anomaly (OR 15.1; p = 0.033), chronic lung diseases (OR 12.5; p = 0.047), weight < 3rd percentile (OR 5.5; p = 0.027), and HAdV B7 (OR 4.2; p = 0.002) had higher incidences of pneumonia. Four with underlying neurologic diseases died of acute respiratory distress syndrome. CONCLUSION: HAdV infections circulate all year-round. HAdV B7 is strongly related to severe infections and pneumonia. Underlying neurologic diseases and prematurity are risk factors for severe HAdV infections.
