Kanjanaphorn Theekhaphorn, Apawan Nookong, Arunrat Srichantaranit — Wed, 28 Aug 2024 00:00:00 +0700

This descriptive comparative study aimed to compare the knowledge of metabolic syndrome in school-aged children and their parents, children’s food consumption behavior, exercise and activity behavior and parental support between children with normal nutritional status and children at-risk of metabolic syndrome. The samples were students aged 10 - 12 years studying in grades 4 - 6 and their parents in Chainat province, divided into normal nutritional group (N = 124) and at-risk group (N = 62). Research instruments included 1) personal information questionnaire, 2) knowledge of metabolic syndrome questionnaire, 3) food consumption behavior questionnaire, and 4) exercise and activity behavior questionnaires for children. The content validity index was 1 and the intraclass correlation coefficient was 0.99, Cronbach’s alpha coefficient were 0.81 and 0.83, respectively. The knowledge of metabolic syndrome questionnaire and parental support questionnaire were used for parents with content validity index of 1 and Cronbach's alpha coefficients of 0.90 and 0.96, respectively. Data were analyzed using descriptive statistics, independent t-test and Mann-Whitney U test. The results indicated that there were no significant differences of knowledge of metabolic syndrome of children and their parents, food consumption behavior and parental support between children with normal nutritional status and children at-risk of metabolic syndrome (z = - 0.400, p > .05, z = - 0.218, p > .05, z = - 0.026, p > .05, t = 0.369, p > .05 respectively). They had significant differences in exercise behavior and physical activities (t = 2.860, p < .05). At-risk children had lower average scores of exercise behaviors and physical activities than children with normal nutritional status. This study therefore suggests that parents, teachers and school administrators should support children to have appropriate exercise and physical activities in order to reduce the risk of metabolic syndrome in school-aged children.

The purpose of this descriptive cross-sectional research was to identify the predictors of COVID-19 surveillance operations of Bangkok Public Health Volunteers (PHVs) by applying the conceptual framework of PRECEDE-PROCEED Model. Three hundred seventy-three Bangkok PHVs, aged 18 and over, were randomly selected using multistage random sampling. A rating scale was used for collecting data from 9-part self-administered questionnaires. The content validity index ranged from 0.93 to 1. The reliability of the questionnaires ranged between 0.72 and 0.92. Data were analyzed using Statistical Package for the Social Sciences including descriptive statistics, Pearson's product-moment correlation coefficient and stepwise multiple regression analysis, with the level of significance equal to .05.
The findings showed that 80.16% of COVID-19 surveillance operations of Bangkok PHVs were at a moderate level. The predicting factors of the COVID-19 surveillance operations of Bangkok PHVs included perceived self-efficacy, occupation, social support, materials and equipment accessibility, prevention policies, age, education, perceived susceptibility, and marital status. These predictors together explained 81.9% of the variance in COVID-19 surveillance operations. Recommendation from this study is that, public health volunteers who work in Bangkok should be periodically prepared in terms of knowledge and skills to enhance their self-confidence in infectious disease surveillance practices in case of future outbreaks. The awareness of policy, materials and equipment support, social support, and perceived self-efficacy should be increased for further effective surveillance operations among people with communicable diseases.

The Roles of Lifeguards in Mitigating Drowning Incidents in Thailand

Chanin Pokabarl — Wed, 28 Aug 2024 00:00:00 +0700

Drowning is a major cause of unintentional death globally, posing significant public health implications that greatly impact economies and societies. According to the World Health Organization (2014), an estimated 91% of drowning incidents occur in countries with low to middle incomes levels. In Thailand, data shows that children under 15 years old have a mortality rate from drowning ranging from 5 to 8.6 per 100,000 population.
The International Life Saving Federation has identified several noteworthy risk factors, which includes the following: lack of knowledge, understanding, and negligence towards potential threats, as well as insufficient information and unrestricted access to hazardous areas, lack of survival skills when facing emergency situations, lack of supervision and vigilance, and other risk factors that may occur simultaneously.
Therefore, in areas with high risk of drowning incidents, it is crucial to have the presence of skilled personnel who can promptly assess risks and provide assistance. Additionally, drowning statistics in the area should be collected to utilize the data for planning prevention measures and reducing potential risks in the future.

Hyperbaric Oxygen Therapy for Treatment of Malayan Pit Viper Bite Patients at Somdej Pranangchaosirikit Hospital

Pichayen Silpsrikul, Terasak Mahamongkol — Wed, 28 Aug 2024 00:00:00 +0700

Malayan pit viper is a snake that can be found in every region of Thailand. Its venom affects the blood coagulation system and local complication at the bite site. Although the chance of death is found to be low, most of the patients often show local complication. The main complication are compartment syndrome and tissue necrosis. In cases that the patient has severe symptoms, surgical treatment is required and many patients become disabled. Somdej Pranangchaosirikit hospital has used hyperbaric oxygen therapy to prevent and treat local complication in patients bitten by Malayan pit viper to reduce disability from local complication. From the data collection in 33 patients from May 2013 - May 2018, it was found that HBO₂T could reduce compartment syndrome and extensive tissue necrosis, as well as reduce the incidence of fasciotomy and debridement, thereby contributing to a reduction in the incidence of Malayan pit viper bite morbidity. There should be clear indications for selecting patients for HBO₂T. However, further randomized control trial study is still needed.
