Background In recent years, smart devices have become an integral part of daily life. However, longitudinal studies, particularly those regarding the relationship between toddlers’ smart device usage and behavioral outcomes, are limited. Understanding the impact of parent–child interactions on this relationship is crucial for enhancing toddlers’ de...

Background In recent years, smart devices have become an integral part of daily life. However, longitudinal studies, particularly those regarding the relationship between toddlers’ smart device usage and behavioral outcomes, are limited. Understanding the impact of parent–child interactions on this relationship is crucial for enhancing toddlers’ de...

Background: In recent years, smart devices have become seamlessly integrated into human life. However, longitudinal studies focusing on their impact on toddlers are lacking. Accordingly, the present study examined the influence of early screen usage time and media content exposure on toddlers’ behavioral performance, along with the positive effects...

Studies have evaluated the impact of environmental exposure to neurotoxic metals on developmental delays (DDs). However, comprehensive understanding regarding the associations between parental and postnatal exposure to metal mixtures and the occurrence of DDs in offspring is limited. In this study, we assessed the relationships between parental and...

Introduction Although mobile devices are used ubiquitously, studies on their detrimental effects on preschoolers are limited. Furthermore, no study has considered shared reading and mobile device usage simultaneously. Therefore, this study examined the effects of mobile devices and shared reading on preschoolers’ development along with the effects...

Indoor air quality and home environmental characteristics are potential factors associated with the onset and exacerbation of allergic diseases. Our study examined the effects of these factors on allergic diseases (i.e., asthma, allergic rhinitis, allergic conjunctivitis, and atopic dermatitis) among preschool children. We recruited a total of 120...

Background: Although studies have reported the effects of inadequate sleep on maternal health, few have examined the relationships of maternal sleep patterns with fetal health and early childhood development. This study investigated maternal sleep duration patterns from early pregnancy to 3-years postpartum and their effects on birth outcomes and...

Abstract People spend most of their time indoors, where they may be exposed to various microorganisms and allergens. In this cross-sectional study, we investigated the relationship between indoor microbial and allergen levels and indoor and outdoor household environmental characteristics. Participants were recruited from an ongoing cohort study in...

We examined the potential mediating roles of anxiety and loneliness on the association of concurrent food insecurity (FI) and being bullied (BB) with suicidal behavior (SB) in Eswatini, a lower-middle-income country. We used data from the Global School-based Student Health Survey (GSHS; N = 3264), which employed a two-stage cluster sampling: first,...

Smokers of any age can reap substantial health benefits from quitting or reducing their smoking. E-cigarettes have been promoted as a potentially promising product for tobacco harm reduction because e-cigarettes deliver nicotine vapor without many of the hazardous chemical combustion byproducts produced by combustible cigarette smoking. However, th...

Air pollution, outdoor residential environment, indoor household characteristics, and parental mental health are potential factors associated with child development. However, few studies have simultaneously analyzed the association between the aforementioned factors and preschool child (aged 2–5 years) development. This study investigated the effec...

Background Evidence of associations between psychological symptoms and tumor necrosis factor (TNF)-α level is scant, as is evidence on sex differences in associations for children and adolescents with obesity. This study examined sex differences in associations between psychological symptoms (self-concept, anxiety, depression, anger, and disruptive...

Introduction In malaria-endemic countries, malaria during pregnancy is associated with adverse birth outcomes, including low birth weight (i.e., <2.5 kg). However, the effects of the widely promoted and recommended approaches of intermittent preventive treatment for malaria in pregnancy and insecticide-treated nets for pregnant women on low birth w...

Background Malawi is a malaria-endemic country. A national malaria communication strategy was adopted to disseminate malaria messages with the aim of improving knowledge and adoption of malaria interventions. Objective To examine the effect of maternal exposure to malaria messages and the medium through which such messages are delivered on insecti...

Background Alcohol-involved riders tend to engage in other risk-taking behaviours such as un-helmeted riding which could further increases injury severity. The combined effect of alcohol-involved and un-helmeted riding on fatal injuries is rarely investigated. This study investigated the interaction effect between blood alcohol concentration and he...

Introduction Although an array of maternal and child-centered risks have been researched, considerably less is known about the effects of paternal influences on child's birth outcomes and early development. This longitudinal study thus examined the effects of paternal influences (parental stress, partner support, childcare and nursing, and father–c...

Background: Self-medication with over-the-counter (OTC) drugs is an important public health concern, especially in the vulnerable population of pregnant women due to potential risks to both the mother and fetus. Few studies have studied how factors, such as knowledge, affect self-medication. This study investigated self-medication and its associat...

Malaria continues to be among the top causes of death in children and insecticide-treated nets (ITNs) are considered among the most effective malaria control methods. However, information on the association between universal ITN coverage and infant mortality is limited. A Cox proportional hazard model was applied to Malawi Demographic and Health Su...

Introduction This study aims to analyse the non-tax-induced price increasing strategies adopted by tobacco industry in Taiwan, a high-income country with comprehensive tobacco control policies but low tobacco taxes and a declining cigarette market. Methods Using governmental tax, price and inflation data, we analysed cigarette sales volume, afford...

Early diagnosis and treatment of childhood fever, an important sign of potentially serious infections such as malaria, is essential for controlling disease progression, and ultimately, preventing deaths. This study examined individual- and community-level factors associated with treatment-seeking behaviors and promptness in these behaviors among ca...

A growing literature indicates that electronic cigarette use increases the risk of subsequent initiation of conventional smoking among cigarette-naïve adolescents in several Western countries. This research assesses the same relationship in an Asian country, Taiwan. The Taiwan Adolescent to Adult Longitudinal Study is a school-based survey that was...

Introduction Adult smoking prevalence in Taiwan rapidly declined from 26.5% in 2005 to 20.0% in 2015. Nevertheless, future projections on smoking-attributable deaths and current per capita consumption do not paint an equally bright picture. Methods We used SimSmoke, a tobacco control simulation model to assess the impact of tax increases and other...

Background: Mental distress patterns in first-time or experienced mothers and fathers during the transition to parenthood have been inadequately studied. This longitudinal study thus investigated changes in depression, anxiety, and health-related quality of life in both parents from early pregnancy until 1 year postpartum. Parity effects were spec...

The increasing popularity of e-cigarettes, especially among adolescents, has alarmed health advocates and government officials, dominating the tobacco control narrative in the past few years. According to the Global Youth Tobacco Survey, the percentage of Taiwanese teenagers reporting use of e-cigarettes in the past 30 days rose from 2.01% (95% con...

The objective of the study was to introduce the methodology and report on cohort description of Taiwan Adolescent to Adult Longitudinal Study (TAALS). TAALS is the first nationwide longitudinal survey among Taiwan adolescents, linked with the National Health Insurance Research Database (NHIRD) to obtain complete medical records of respondents in th...
