All-cause excess mortality among end-stage renal disease (ESRD) patients during the COVID-19 pandemic in Thailand: a cross-sectional study from a national-level claims database.

OBJECTIVES: COVID-19 infection increased nephrology-related risks and mortality rate among end-stage renal disease (ESRD) patients. The pandemic also disrupted essential healthcare services. We aim to explore all-cause excess mortality among ESRD patients who were members of the Universal Coverage Scheme (UCS), the largest public health insurance scheme in Thailand covering citizens who are not employed in the formal sector, including children and older persons. DESIGN: A cross-sectional study. SETTING: We retrieved the dataset from the UCS claims database-electronic health records used for processing healthcare expense claims from medical facilities of all UCS members. This database links mortality outcome to civil registration. We employed the WHO's excess mortality methodology using pre-pandemic data to estimate expected deaths during the pandemic period (March 2020 to August 2022). PARTICIPANTS: This study included ESRD patients from across Thailand, covered by the UCS. PRIMARY OUTCOME MEASURE: Excess deaths are the difference between predicted and reported deaths. RESULTS: Over a 30-month period of the pandemic, the total number of all-cause excess deaths among ESRD patients was 4966 (male 1284; female 3682). The excess death per 100 000 ESRD patients was 3601 (male 2012; female 4969). The relative excess death was 5.7% of expected deaths (95% CI 1.7%, 10.0%). The excess deaths were highly concentrated among patients aged 65 and older. CONCLUSION: ESRD patients are significantly more vulnerable to pandemic-related mortality than the general population. Health systems' capacity to contain the pandemic at varying virulence and maintain essential health services for ESRD patients might be related to the size of excess deaths at different periods. The observed excess deaths highlight the importance of established strategies to reduce all-cause mortality such as rapid vaccine rollout for ESRD patients and sustaining dialysis and other essential services for older patients and other high-risk groups.

Utilisation of and factors associated with non-COVID-19 healthcare services in public facilities amongst cross-border migrants in Thailand, 2019-2022.

BACKGROUND: It is believed that the COVID-19 pandemic might disrupt routine healthcare services. A vulnerable group such as cross-border migrants is of critical concern if the pandemic affects their service utilisation. In this study, we aim to explore the impact of COVID-19 and other related factors on non-COVID-19 service amongst cross-border migrants in Thailand. METHODS: We conducted an ecological time-series cross-sectional analysis using secondary data from 2019 to 2022, focusing on insured and non-insured migrants in a unit of a provincial monthly quarter. We obtained data on registered migrants from the Ministry of Labour and inpatient visits from the Ministry of Public Health (MOPH). Our analysis involved descriptive statistics and a random-effects negative binomial regression, considering variables such as COVID-19 cases, number of hospital beds, registered regions, and COVID-19 waves. We assessed inpatient utilisation number and rate as our primary outcomes. RESULTS: The admission numbers for insured and non-insured migrants in all regions increased 1.3-2.1 times after 2019 despite a decrease in the numbers of registered migrants. The utilisation of services for selected communicable and non-communicable diseases and obstetric conditions remained consistent throughout 2019-2022. The admission numbers and rates were not associated with an increase in COVID-19 incidence cases but significantly enlarged as time passed by compared to the pre-COVID-19 period (44.5-77.0% for insured migrants and 15.0-26.4% for non-insured migrants). Greater Bangkok saw the lowest admission rate amongst insured migrants, reflected by the incidence rate ratio of 5.7-27.5 relative to other regions. CONCLUSION: The admission numbers and rates for non-COVID-19 healthcare services remained stable regardless of COVID-19 incidence. The later pandemic waves (Delta and Omicron variants) were related to an increase in admission numbers and rates, possibly due to disruptions in outpatient care, leading to more severe cases seeking hospitalisation. Lower admission rates in Greater Bangkok may be linked to the fragmentation of the primary care network in major cities and the disintegration of service utilisation data between private facilities and the MOPH. Future research should explore migrant healthcare-seeking behaviour at an individual level, using both quantitative and qualitative methods for deeper insights.

Characteristics of distance education interventions and related outcomes in primary school children during COVID-19 pandemic: A systematic review.

The COVID-19 pandemic containment measures such as school closures remarkably disrupt the educational system, from in-person learning to remote or distance education with different interventions. This study aimed to identify the characteristics of interventions in remote or distance education during the COVID-19 pandemic and evaluate the outcomes of each intervention. A systematic review was conducted between October 2021 and May 2022 using four databases. Finally, 22 studies met the eligibility criteria and were included for data analysis. Most of the interventions were synchronous student-centered approaches followed by asynchronous student-centered approaches and mixed-learning through online channels such as desktop- and web-based modality. Remote or distance education is effective in academic development in any learning approach while having mixed effects in student attitudes and perceptions. Academic-related behaviors were most engaged by students in synchronous student-centered approaches. Finally, difficulties or burdens, and mental health or social interaction were similar for all learning approaches in technological problems and support systems from families and teachers. Synchronous student-centered approaches should be the main method of education, but other approaches can be used to complement based on the students' needs. Finally, educational infrastructure and support from teachers and parents are also necessary in remote or distance education. Further studies are needed to focus on primary school students, especially in low-income regions, and apply a randomized study design.

Patterns and correlates of physical activity and sedentary behavior among Bangkok residents: A cross-sectional study.

BACKGROUND: Physical inactivity and sedentary behavior are significant risk factors for various non-communicable diseases. Bangkok, Thailand's capital, is one of the fastest-growing metropolitans in Southeast Asia. Few studies have investigated the epidemiology of physical activity and sedentary behavior among Bangkok residents. This study aims to investigate the prevalence of combined physical activity and sedentary behavior patterns among Bangkok residents and examine relationships between participants' characteristics and the combined movement patterns. METHODS: We analyzed data from the nationally representative 2021 Health Behavior Survey conducted by the Thailand National Statistical Office. The Global Physical Activity Questionnaire was used to assess physical activity and sedentary behavior. 'Sufficiently active' was defined as meeting the World Health Organization's guidelines for aerobic physical activity (≥150 minutes of moderate-to-vigorous physical activity per week). 'Low sedentary time' was defined as sitting for ≤7 hours per day. Participants were categorized into one of four movement patterns: highly active/low sedentary, highly active/highly sedentary, low active/low sedentary, and low active/highly sedentary. Multinomial logistic regression was used to identify the factors associated with each group of four movement patterns. RESULTS: Among the 3,137 individuals included in the study, the majority were categorized as highly active/highly sedentary (64.8%), followed by highly active/low sedentary (17.9%) and low active/highly sedentary (14.3%). Only a few (3.0%) of participants were categorized as being low active/low sedentary. Compared to males, female participants had a significantly higher likelihood of belonging to the highly active/low sedentary (AOR = 1.69, 95%CI: 1.25, 2.28) or highly active/highly sedentary (AOR = 1.51, 95%CI: 1.19, 1.93) group, rather than the low active/high sedentary group. Compared to unemployed/retired participants, those in labor-intensive occupations had a significantly higher likelihood of being in the highly active/low sedentary group (AOR = 1.89, 95%CI: 1.22, 2.94). Compared to participants with no chronic physical conditions, participants who reported multimorbidity had a significantly lower likelihood of being in the highly active/low sedentary group (AOR = 0.60, 95%CI: 0.37, 0.98). CONCLUSION: This study provides valuable insights into the patterns of physical activity and sedentary behavior among residents of Bangkok using up-to-date data. The majority belonged to the highly active/highly sedentary group, followed by the highly active/low sedentary group. Correlates such as sex, occupation, and chronic conditions were associated with these patterns. Targeted interventions in recreational activities, workplaces, and urban areas, including screen time control measures, movement breaks and improved built environments, are crucial in reducing sedentary behavior and promoting physical activity.

Self-Reported Anxiety and Depression among Parents of Primary School Children during the COVID-19 Pandemic in Thailand, 2022.

One significant concern during the COVID-19 pandemic is parents' mental health, which may consequently affect children's health and well-being. The objective of this study is to investigate generalized anxiety and depression in parents of primary-school-aged children and identify risk factors for mental health problems. A cross-sectional survey comprising 701 parents of primary school children in five of Thailand's major provinces was carried out from January to March 2022. Generalized anxiety and depression levels were assessed using the GAD-7 and PHQ-9. Logistic regression was performed to determine the effects of independent variables on anxiety and depression. Results showed that the prevalence of generalized anxiety and depression was 42.7% and 28.5%, respectively, among Thai parents. Three strong associative factors included: (1) having a youngest child with mental health problems; (2) not assisting their children every day; and (3) drinking alcohol. These findings show that the parents must deal with several difficulties when trying to maintain work and parenting duties while being confined at home during emergency situations. The government should provide sufficient assistance to parents who lack skills in handling children with emotional and behavioral problems. Meanwhile, health promotion to reduce alcohol consumption should continue to be an area of focus.

Perceived Barriers of Accessing Healthcare among Migrant Workers in Thailand during the Coronavirus Disease 2019 (COVID-19) Pandemic: A Qualitative Study.

The outbreak of Coronavirus Disease 2019 (COVID-19) has threatened health and well-being in all populations. This impact is also deepening structural inequalities for migrant workers in Thailand. Due to their vulnerability and limited opportunity to access health services, they have greater risks in many health aspects compared to other populations. This qualitative study sought to examine the key health concerns and barriers during the COVID-19 pandemic on healthcare access among migrant workers in Thailand through the lens of policymakers, healthcare professionals, experts on migrant health, and migrant workers. We conducted 17 semi-structured in-depth interviews of stakeholders from health and non-health sectors in Thailand from July to October 2021. The interviews were transcribed and analyzed using both deductive and inductive thematic approaches. Thematic coding was applied. The results showed that financial constraints were a major barrier for healthcare access among migrant workers. These included affordability of healthcare and difficulty accessing funds (migrant health insurance). Structural barriers included some health facilities opening for emergency cases only. Insufficient healthcare resources were profound during the peak of positive cases. Cognitive barriers included negative attitudes and diverse understanding of healthcare rights. Language and communication barriers, and a lack of information also played an important role. Conclusion, our study highlights healthcare access barriers to migrant workers in Thailand during the COVID-19 pandemic. Recommendations for future resolution of these barriers were also proposed.

Psychosocial Problems Among Primary School Children in Thailand During the COVID-19 Pandemic, 2022.

Background: During the COVID-19 pandemic, primary school children are particularly vulnerable as restriction measures have caused a huge impact on their health and well-being. This study aims to assess the prevalence of mental health among primary school children in Thailand during the COVID-19 pandemic and identify factors associated with psychosocial problems. Methods: A survey was conducted among 701 Thai parents of primary school children from January to March 2022 - when teaching modalities between onsite and online learning were alternated. Parents were requested to assess the mental health of their youngest child at primary school age level. Psychosocial problems were measured by the Strengths and Difficulties Questionnaire (SDQ) with a total score of 40, based on 4 domains (emotion, behavior, hyperactivity, and relationship). Independent variables included (1) parental/household factors, (2) children characteristics, and (3) online learning-related issues. The dependent variable was the prevalence of children with a total score of 14-40, which indicates at risk and/or having mental health problems. The analysis was performed using logistic regression model. Results: Thai parents reported that 41.1% of children had psychosocial problems. Children in a single-parent family (adjusted odds ratio [AOR] = 1.7; 95% confidence interval (CI) = 1.1-2.8), male children (AOR = 1.7, 95% CI = 1.2-2.4), and children who did not receive adequate assistance for online learning from their parents (AOR = 2.1, 95% CI = 1.1-4.0) significantly faced greater odds of mental health problems. Conclusion: The prevalence of Thai primary school children confronting psychosocial difficulties during the COVID-19 pandemic increased, with significant concern. Public health interventions that aim to protect the mental health of primary school children during the pandemic should be introduced and targeted male children and those living with a single parent. Social support that facilitates online learning for children whose parents have limited capacity in supporting them should be implemented.

Patterns of Physical Activity and Sedentary Behavior During the COVID-19 Pandemic in the Thai 2021 National Health Survey.

BACKGROUND: Understanding patterns of physical activity and sedentary behavior is essential, but evidence from low- and middle-income countries remains limited. This study aimed to investigate the prevalence of physical activity and sedentary behavior in the Thai population; their sociodemographic correlates; and the contribution of specific domains to total physical activity. METHODS: We analyzed data from the 2021 Health Behavior Survey, a nationally representative survey, conducted by the Thailand National Statistical Office during the COVID-19 pandemic. Physical activity and sedentary behavior were assessed using the Global Physical Activity Questionnaire. "Sufficiently active" was defined according to the World Health Organization guidelines. "Highly sedentary" was defined as sitting ≥7 hours per day. The contribution of work, transport, and recreational physical activity was determined as the proportion of total physical activity. Multivariable logistic regression was conducted to determine the correlates of being sufficiently active and being highly sedentary. RESULTS: Of the total study population (N = 78,717), 71.9% were sufficiently active, whereas 75.8% were highly sedentary. Females, having a labor-intensive work, and living in Bangkok had a higher likelihood of being sufficiently active. Those with higher education and income levels, and living in Bangkok and the Central region had a greater likelihood of being highly sedentary. The work domain contributed the highest proportion toward physical activity (82.1%), followed by the recreation (10.0%) and transport domains (7.9%). CONCLUSIONS: Policies should focus on promoting transport and recreational physical activity and activity that can break up sedentary behavior among adults because when countries become technologically advanced, physical activity at work declines.

Learning from pandemic responses: Informing a resilient and equitable health system recovery in Thailand.

This article is part of the Research Topic 'Health Systems Recovery in the Context of COVID-19 and Protracted Conflict'. The third quarter of 2022 saw COVID-19 cases and deaths in Thailand reduced significantly, and high levels of COVID-19 vaccine coverage. COVID-19 was declared an "endemic" disease, and economic activities resumed. This paper reviews pre-pandemic health systems capacity and identifies pandemic response strengths, weaknesses and lessons that guided resilient and equitable health system recovery. Robust health systems and adaptive strategies drive an effective pandemic response. To support health system recovery Thailand should (1) minimize vulnerability and extend universal health coverage to include migrant workers and dependents; (2) sustain provincial primary healthcare (PHC) capacity and strengthen PHC in greater Bangkok; (3) leverage information technology for telemedicine and teleconsultation; (4) enhance and extend case and event-based surveillance of notifiable diseases, and for public health threats, including pathogens with pandemic potential in wildlife and domesticated animals. This requires policy and financial commitment across successive governments, adequate numbers of committed and competent health workforce at all levels supported by over a million village health volunteers, strong social capital and community resilience. A strengthened global health architecture and international collaboration also have critical roles in establishing local capacities to develop and manufacture pandemic response products through transfer of technology and know-how. Countries should engage in the ongoing Inter-government Negotiating Body to ensure a legally binding instrument to safeguard the world from catastrophic impacts of future pandemics.

Cost-Effectiveness Analysis of COVID-19 Vaccine Booster Dose in the Thai Setting during the Period of Omicron Variant Predominance.

The Thai government implemented COVID-19 booster vaccines to prevent morbidity and mortality during the spreading of the Omicron variant. However, little is known about which types of vaccine should be invested in as the booster dose for the Thai population. This study aims to investigate the most cost-effective COVID-19 vaccine for a booster shot as empirical evidence for Thai policymakers. This study applied a stochastic simulation based on a compartmental susceptible-exposed-infectious-recovered model and included system dynamics in the model. We evaluated three scenarios: (1) No booster, (2) A viral vector vaccine as the booster dose, (3) An mRNA vaccine as the booster dose. The incremental cost-effectiveness ratio (ICER) was calculated based on provider perspectives. We found the number of cases in scenarios with viral vector and mRNA booster doses to be lower than in the non-booster group. Likewise, the number of deaths in the viral vector and the mRNA booster scenarios was threefold lower than in the no-booster scenario. Moreover, the estimated grand cost for the no-booster scenario was over 100 billion baht, while viral vector and mRNA scenario costs were 70 and 64.7 billion baht, respectively. ICER shows that viral vector and mRNA scenarios are more cost-effective than the no-booster scenario. Viral vector booster shot appeared to be slightly more cost-effective than mRNA booster shot in terms of death aversion. However, being boosted by an mRNA vaccine seemed slightly more cost-effective than a viral vector vaccine concerning case aversion. In conclusion, policies to promote COVID-19 booster shots in the Thai population by either mRNA or viral vector vaccines are likely to be worthwhile for both economic and public health reasons.

Real-World Effectiveness of COVID-19 Vaccines against Severe Outcomes during the Period of Omicron Predominance in Thailand: A Test-Negative Nationwide Case-Control Study.

Due to the widespread Omicron variant of SARS-CoV-2 in Thailand, the effectiveness of COVID-19 vaccines has become a major issue. The primary objective of this study is to examine the real-world effectiveness of COVID-19 vaccines based on secondary data acquired under normal circumstances in a real-world setting, to protect against treatment with invasive ventilation of pneumonia during January to April 2022, a period when Omicron was predominant. We conducted a nationwide test-negative case-control study. The case and control were matched with a ratio of 1:4 in terms of age, date of specimen collection, and hospital collection specimen and the odds ratio was calculated using conditional logistic regression. Overall, there was neither a distinction between mix-and-match regimens and homologous mRNA regimens against severe symptoms, nor was there a decline of the protective effect over the study period. The third and fourth dose boosters with ChAdOx1 nCoV-19 or mRNA vaccines provided high levels of protection against severe outcomes, approximately 87% to 100%, whereas two doses provided a moderate degree (70%). Thus, this study concludes that current national vaccine strategies provide favourable protective benefits against the Omicron variant. All Thais should receive at least two doses, while high-risk or vulnerable groups should be administered at least three doses.

Family Health among Families with Primary School Children during the COVID Pandemic in Thailand, 2022.

Despite evidence suggesting that the COVID pandemic has negatively affected the mental health and well-being of school aged children and parents, there are limited studies describing the state of family well-being. This study aimed to use the family health lens to assess the well-being of Thai families with primary school children and to identify its associated factors. A cross-sectional survey was conducted during January and March 2022, a period of school closure when onsite education was replaced by online education from time to time. The family health scale (FHS) questionnaire survey was carried out among 701 parents of Thai families with primary school children. The questionnaire comprised 10 questions regarding family belief, health, relationships, financial security, and housing environment. Independent variables included: (1) parental/household factors; (2) online learning related issues; (3) children's mental health; and (4) parents' health behaviors. Multinomial logistic regression was undertaken. Results showed that half of Thai families (54.6%) reported having moderate health status. Factors that were associated with lower levels of family health, such as poor or moderate levels, included families with a child that had mental health problems (adjusted odd ratio (AOR) = 5.0 [95% CI = 2.6-9.5] for poor v. excellent, and AOR = 2.7 [95% CI = 1.9-4.0] for moderate v. excellent), single parents (AOR = 2.5 [95% CI = 1.2-5.2] for poor v. excellent), a higher number (≥3) of children (AOR = 2.1 [95% CI = 1.0-4.0] for moderate v. excellent), and smoking parents (AOR = 6.5 [95% CI =1.2-34.8] for poor v. excellent). During health emergencies, health policy for providing adequate assistance to single parents, especially those that have a child with mental health problems, is of utmost importance. The design of health promotion activities and interventions should be targeted not only at single families, but also families with higher numbers of children and parents who smoke at home.

Distribution of Physicians to Public Health Facilities and Factors Contributing to New Medical Graduates Serving in Public Facilities, 2016-2020, Thailand.

Background: In Thailand, the shortage and maldistribution of physicians in the public sector is a critical public health problem. The aims of this study are to describe the retention situation of new physicians and to determine factors associated with new physicians' decision to serve in public facilities. Methods: Data of new physicians from the Human Resource Office of the Permanent Secretary System (HROPS) were analysed in order to describe the retention situation of new physicians. A retrospective cohort study was conducted to determine factors associated with new physicians' decision to remain in public service. The data were collected between Oct 2021 and Jan 2022. Cox regression was performed. Results: According to the HROPS database, most new physicians remained in hospitals affiliated to the Office of the Permanent Secretary (OPS) of the Ministry of Public Health (MOPH) (83.5%). Among the physicians resigning from MOPH hospitals, 80.6% resigned due to career factors. From a retrospective cohort study, physicians in the special recruitment track had the lowest incidence rate of resigning. In terms of satisfaction, most physicians were least satisfied with salary levels and workload. The majority of physicians felt satisfied with being close to their families. The Cox regression revealed that physicians graduating from private medical schools or from abroad had a higher risk of leaving public facilities. Conclusion: To lessen the burden of physician shortage and maldistribution, the proportion of students recruited in the special track should be enhanced. High workload and inappropriate income should be addressed. Allocating new physicians to work in their hometown is recommended.

Risk Communication Distributed among Migrant Workers during the COVID-19 Crisis in Thailand: Analysis on Structural and Networking Gaps.

Language and cultural barriers among migrant workers hamper access to health risk information. This study aims to explore health risk communication structure and processes and identify the communication network of migrant workers during the COVID-19 pandemic in Thailand. This study used a parallel mixed-methods design combined with in-depth interviews and questionnaires for social network analysis from November 2020 to June 2021 in the headquarter district of Samut Sakhon, Ranong, and Phuket provinces. We conducted purposive sampling of representatives from public and non-public organisations and local communities. Thirty-six key informants participated in in-depth interviews, and fifty-six respondents completed the questionnaire for social network analysis. Although health risk communication included various activities, there was no formal governing body responsible for health risk communication among migrants, and monitoring and evaluation of communication process were not well-implemented. The health risk communication network was centralised, especially in the rural area; however, migrant health volunteers (MHVs) and local media were key sources of information for most migrants in communities. Overall, a governing body led by the government with intersectional collaboration and a health risk communication process should be promoted while considering migrants' characteristics and concerns. The health risk communication network should identify key communicators such as MHVs and local media. This can be an effective strategy to fill the gap of information dependency.

Forecasted Trends of the New COVID-19 Epidemic Due to the Omicron Variant in Thailand, 2022.

Thailand is among many countries severely affected by COVID-19 since the beginning of the global pandemic. Thus, a deliberate planning of health care resource allocation against health care demand in light of the new SARS-CoV-2 variant, Omicron, is crucial. This study aims to forecast the trends in COVID-19 cases and deaths from the Omicron variant in Thailand. We used a compartmental susceptible-exposed-infectious-recovered model combined with a system dynamics model. We developed four scenarios with differing values of the reproduction number (R) and vaccination rates. In the most pessimistic scenario (R = 7.5 and base vaccination rate), the number of incident cases reached a peak of 49,523 (95% CI: 20,599 to 99,362) by day 73, and the peak daily deaths grew to 270 by day 50. The predicted cumulative cases and deaths at the end of the wave were approximately 3.7 million and 22,000, respectively. In the most optimistic assumption (R = 4.5 and speedy vaccination rate), the peak incident cases was about one third the cases in the pessimistic assumption (15,650, 95% CI: 12,688 to 17,603). In the coming months, Thailand may face a new wave of the COVID-19 epidemic due to the Omicron variant. The case toll due to the Omicron wave is likely to outnumber the earlier Delta wave, but the death toll is proportionately lower. Vaccination campaigns for the booster dose should be expedited to prevent severe illnesses and deaths in the population.

Real-World Effectiveness of Mix-and-Match Vaccine Regimens against SARS-CoV-2 Delta Variant in Thailand: A Nationwide Test-Negative Matched Case-Control Study.

The objective of this study is to explore the real-world effectiveness of various vaccine regimens to tackle the epidemic of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Delta variant in Thailand during September-December 2021. We applied a test-negative case control study, using nationwide records of people tested for SARS-CoV-2. Each case was matched with two controls with respect to age, detection date, and specimen collection site. A conditional logistic regression was performed. Results were presented in the form vaccine effectiveness (VE) and 95% confidence interval. A total of 1,460,458 observations were analyzed. Overall, the two-dose heterologous prime-boost, ChAdOx1 + BNT162b2 and CoronaVac + BNT162b2, manifested the largest protection level (79.9% (74.0-84.5%) and 74.7% (62.8-82.8%)) and remained stable over the whole study course. The three-dose schedules (CoronaVac + CoronaVac + ChAdOx1, and CoronaVac + CoronaVac + BNT162b2) expressed very high degree of VE estimate (above 80.0% at any time interval). Concerning severe infection, almost all regimens displayed very high VE estimate. For the two-dose schedules, heterologous prime-boost regimens seemed to have slightly better protection for severe infection relative to homologous regimens. Campaigns to expedite the rollout of third-dose booster shot should be carried out. Heterologous prime-boost regimens should be considered as an option to enhance protection for the entire population.

Thailand Achievement of SDG Indicator 4.2.1 on Early Child Development: An Analysis of the 2019 Multiple Indicator Cluster Survey.

The early years of a child's life are the foundation for their future capability development. Poor health, hunger, poverty, low parental education, lack of parental interaction, high screen time, and poor housing environment hamper their development. There is little evidence of a link between early child development (ECD) and sociodemographic factors in Thailand. In response to monitoring the achievement of SDG target 4.2.1 (the proportion of young children who are developmentally on track in health, learning and psychosocial well-being) as required by all UN Member States, this study analyses the prevalence of appropriate levels of ECD and its correlates of Thai children aged 3 to 4 years. A cross-sectional study of the 6th Multiple Indicator Cluster Survey (MICS) data in 2019 conducted by the National Statistical Office was employed. Face-to-face interviews with mothers and/or legal guardians were conducted. A total of 5787 children aged 3 to 4 were enrolled in this study. The majority of participants, approximately 92.3%, had achieved an appropriate level of ECD index, defined as children who were developmentally on track in at least three out of these four domains: cognitive, physical, social, and learning. Multivariate logistic regression showed that girls had a higher appropriate development index than boys (Adjusted Odds Ratio [AOR] = 1.56, 95% Confidence Interval [95% CI] 1.28-1.90; children living in the 5th wealth quintile had a higher appropriate index than those in a less well-off family the first wealth quintile (AOR = 2.92, 95% CI: 1.86-4.58. Univariate logistic regression showed children living with parents achieving post-secondary education had a significantly greater appropriate index than children living with parents completing secondary education or below (Crude OR = 1.95, 95% CI 1.47-2.58); children who had appropriate parental interactions of more than four out of six interactions, had a significantly higher chance of having an appropriate index than less than four interactions (Crude OR = 1.52, 95% CI 1.14-2.04). Multi-sectoral policies to support child development in low socio-economic households should be strengthened. In addition, family and community should promote parental interactions through reading and playing with young children. Future studies which directly measure ECD in conjunction with regular monitoring through MICS are recommended.
