BackgroundHand, foot and mouth disease (HFMD) is a major communicable disease in children ≤6 years old, particularly in several countries in the Asia-Pacific Region, including Thailand. HFMD impacts public health and the economy, especially in northern Thailand.MethodsA prospective cohort study was conducted to estimate the incidence rate and to identify the serotype and clinical features of HFMD among children in northern Thailand. A validated questionnaire and throat swab were used for data collection. Polymerase chain reaction (PCR) was used to detect human enterovirus and identify its serotypes. Participants were recruited from 14 hospitals in two provinces in northern Thailand, specifically, Chiang Rai and Pha Yao Province, between January 1, 2016, and December 31, 2016. Chi-square or Fisher’s exact test was used to detect the associations of signs and symptoms with HFMD serotype. Logistic regression was used to detect the associations of variables with a positive enterovirus at alpha = 0.05.ResultIn total, 612 children aged ≤6 years from Chiang Rai and Pha Yao Province who were diagnosed with HFMD by a throat swab were recruited for the analysis. Approximately half of the cohort was male (57.2%), 57.5% was aged < 2 years, and 57.5% lived in rural areas. The incidence rate was 279.72/100,000 person-years in Chiang Rai Province and 321.24 per 100,000 person-years in Pha Yao Province. Additionally, 42.5% of children were positive for human enterovirus; among these children, 56.1% were positive for enterovirus-A (EV-A), 17.7% were positive for coxsackievirus (CV), and 26.2% were positive for other human RNA enteroviruses. During the study period, 21 distinct outbreaks of HFMD were recognized. Four to five patients (total 92 patients) were selected from each outbreak for identifying its serotype; enterovirus-A71 (EV-A71) was detected in 34.8% of HFMD cases, coxsackievirus-A16 (CV-A16) in 26.1%, coxsackivirus-A6 (CV-A6) in 15.2%, coxsackievirus-A10 (CV-A10) in 10.9%, coxsackievirus-A4 (CV-A4) in 2.2%, coxsackievirus-B2 (CV-B2) in 2.2%, human rhinovirus in 2.2%, and unknown serotype in 6.4%. Multivariable analysis demonstrated that a history of breastfeeding for ≤6 months was associated with a higher chance of enterovirus infection than a history of breastfeeding > 6 months, and children who had mother who worked as farmers, daily wage employees, and unprofessional skilled jobs had a greater chance of enterovirus infection than those who had unemployed mothers. Coxsackievirus-infected children had a higher rate of rashes on the buttocks, knee, and elbow and fever but a lower rate of lethargy and malaise than EV-A71-infected children.ConclusionsEV-A71 is a major cause of HFMD in children < 6 years old in northern Thailand, but rash, fever, and mouth ulcers are mostly found in participants with coxsackievirus infection. Breastfeeding should be promoted during early childhood for at least 6 months to prevent HFMD particularly those mother who are working in unprofessional skill jobs.Electronic supplementary materialT...
BackgroundAlcohol use impacts several dimensions, including physical health, mental health, families, and social interactions. This study aimed to estimate the prevalence and to determine the factors associated with alcohol use among Akha and Lahu hill tribe youths in Chiang Rai, Thailand.MethodsAn analytic cross-sectional design was applied to obtain key data on these associations. The study sample was Akha and Lahu hill tribe youths aged 15-24 years who lived in 30 selected hill tribe villages. A questionnaire was developed from an in-depth interview and group discussion and tested for validation and reliability before use. Descriptive statistics were used to demonstrate the general characteristics, and Chi-square test and logistic regression were used to detect associations between variables at α=0.05.ResultsA total of 737 subjects were recruited into the study, of whom 50.0% were Lahu. The average age was 17.9 years, 80.7% were single, 71.1% were Christian, 65.9% graduated secondary school, and 65.7% had their major source of income from their parents. Overall, 17.3% smoked and 45.0% drank alcohol. Among the drinkers, 79.8% drank beer, 61.5% started drinking at an age of 15-19 years, 86.8% had drank for < 5 years, 42.5% were persuaded to drink by their peers, 20.2% suffered an accident after alcohol use, and 17.2% had experienced unsafe sex after drinking alcohol. In the multiple logistic regression, six variables were associated with alcohol use among the Akha and Lahu youths. Males had greater odds of alcohol use than females (ORadj = 3.50, 95% CI = 2.24-5.47). Buddhists had greater odds of alcohol use than Christians (ORadj = 1.88, 95% CI = 1.17-3.04). Participants who were unemployed, employed, and in other categories of occupation had greater odds of alcohol use than those who were students (ORadj = 2.20, 95% CI = 1.23-3.92; ORadj = 6.89, 95% CI = 3.38-13.89; and ORadj = 2.96, 95% CI = 1.01-8.59, respectively). Participants whose fathers were daily wage workers had greater odds of alcohol use (ORadj = 2.89; 95% CI = 1.23-6.79) than those whose parents worked in agriculture, and those whose fathers used alcohol had greater odds of alcohol use than those whose fathers did not use alcohol (ORadj = 2.17, 95% CI = 1.40-3.35). Finally, those who had 6-10 and ≥ 11 close friends living in the same village who used alcohol had greater odds of alcohol use (ORadj = 8.51, 95% CI = 3.10-23.3; and ORadj = 3.84, 95% CI = 1.15-12.77, respectively).ConclusionTo reduce the initiation of alcohol use among Akha and Lahu youths, public health intervention programs should focus on males who are not attending school and should be implemented for both their family members and peers.
Background Methamphetamine use not only impacts health and the economy but also causes social impairment, particularly among the poorly educated and underprivileged young populations among the hill tribes in northern Thailand. Youths are the most vulnerable population for methamphetamine use due to various factors, including parenting styles, childhood exposure, and location of the village. This qualitative approach aimed to investigate the perceived factors influencing the initiation of methamphetamine use among the Akha and Lahu youths in northern Thailand. Methods A qualitative approach was used to elicit the information from key informants of Akha and Lahu youths who lived in villages in Chiang Rai province. A sixteen-question guideline was developed and examined for quality by three experts in the field and piloted before use. In-depth interviews were conducted among 19 Akha and 22 Lahu youths, serving as key informants from four villages, in a private and confidential room in their villages between June and August 2018. Each interview lasted approximately an hour. A thematic analysis was performed to evaluate the information. Results In total, 41 participants (19 Akha and 22 Lahu) from 4 villages participated in the study. According to the context and content obtained, four major perceived factors (low self-esteem, family member use, positive expectation regarding methamphetamine use, and availability), and five supportive factors (social norm perception, school dropout, family level problems, poor economic, and no Thai citizenship) were found to contribute to the initiation of methamphetamine use among the Akha and Lahu youths in northern Thailand. Conclusions Akha and Lahu youths are initiating methamphetamine use due to several factors, including living in a poor family and in a remote area. All relevant government agencies with a mission to prevent and protect against methamphetamine use should consider the perceived factors influencing the initiation of methamphetamine use in these populations in order to develop a powerful program to stop methamphetamine use.

Background Methamphetamine (MA) is a commonly used substance among youths, particularly those who are living in poor economic conditions with low levels of education and who have had bad childhood experiences. The Akha and Lahu hill tribe youths living on the Thailand-Myanmar-Laos border are identified as the group most vulnerable to MA use in Thailand. The study aimed to estimate the prevalence of MA use and determine its associations with childhood experiences among Akha and Lahu youths aged 15-24 years in northern Thailand. Methods A cross-sectional study was performed. Validated and sealed questionnaires were used to gather information from participants after obtaining the informed consent form. Questionnaires were completed by participants and their parents at home. Logistic regression was used to identify the associations between variables at the α = 0.05 level. Results A total of 710 participants participated in the study: 54.2% were Akha, 52.5% were females, 50.6% were aged 15-17 years, and 11.4% did not have Thai identification card (ID) cards. The overall prevalence of MA use at least once among Akha and Lahu youths was 14.5%. After controlling for all potential confounding factors, 8 variables were found to be associated with MA use. Males had a greater chance of MA use than females (AOR = 4.75; 95% CI = 2.27-9.95). Participants aged 21-24 years had a greater chance of MA use than those aged 15-17 years (AOR = 2.51; 95% CI = 1.11-5.71). Those who had a family member who used MA had a greater chance of MA use than those who did not (AOR = 5.04; 95% CI =
Background Triglycerides are lipids in the human body that are produced from the consumption of daily food and drink. However, elevated serum triglycerides, also known as hypertriglyceridemia (HTG), are key biomarkers indicating an unhealthy status and increased risks of cardiovascular diseases (CVDs) and pancreatitis. Different groups of people have different patterns and styles of cooking and different patterns of consumption, such as hill tribe people, who have their own unique culture and cooking practices. This study aimed to estimate the prevalence of and determine the factors associated with HTG among the hill tribe population in Thailand. Method A cross-sectional study was performed. Data and a-5 mL blood sample were collected from participants who were members of one of the six main hill tribes in Thailand: Akah, Lahu, Hmong, Yao, Karen, and Lisu. People who lived in 30 selected hill tribe villages and aged 30 years over were asked to participate the study. Pearson correlation and logistic regression were used to detect the correlations and determine the associations between variables, respectively, at a significant level of α = 0.05. Results A total of 2552 participants participated this study; 65.9% were females, 72.35% were aged 40–69 years, 76.7% had no education, 48.7% worked in the agricultural section, and 71.2% had an annual income of less than 50,000 baht/family. Regarding the triglyceride level, 41.7% of participants had elevated levels of serum triglyceride or HTG; 16.4% had a borderline high level, and 25.3% had a high level. After controlling for all potential confounder factors, three variables were found to be associated with elevated serum triglycerides. Those who were members of the Lahu and Hmong tribes were 1.62 times (95%CI = 1.25–2.01) and 1.63 times (95%CI = 1.23–2.16) more likely to have elevated serum triglycerides than those who were members of the Akha tribe, respectively. Those who used a high quantity of cooking oil for daily cooking were 0.73 times less likely to have an abnormal level of triglycerides than those who used a low quantity of cooking oil for daily cooking (95%CI = 0.58–0.91), and those who had a waist circumference indicating obesity were 1.28 times more likely to have an abnormal level of triglycerides than those who had a normal waist circumference (95%CI = 1.08–1.52). Conclusion Public health programs that focus on encouraging people to have regular exercise to reduce their body weight, particularly in some tribes, such as Lahu and Hmong, should be implemented.
Background: Depression is a silent health problem that can lead to severe and sometimes fatal outcomes if individuals are not diagnosed and treated properly; this is particularly true in populations with limited education, low economic status and several barriers to accessing health services, such as the hill tribe people in Thailand. Methods: This cross-sectional study aimed to explore the prevalence of and factors associated with depression among hill tribe individuals aged 30 years and over. A validated questionnaire and the Patient Health Questionnaire-9 (PHQ-9) were used for data collection in an interview format in a private and confidential room.Logistic regression was used to detect the associations of variables with depression at a significance level of α ¼ 0.05. Results: A total of 2,552 participants were recruited for the analysis; 65.9% were females, 79.9% were married, 35.8% were aged 50 years and over, and 54.2% were Buddhist. The majority were uneducated (76.7%), were agriculturalists (48.4%), and had a low family income (71.2%). The overall prevalence of depression was 12.0%. In the multivariate analysis, eight variables were found to be significantly associated with depression among hill tribe adults aged 30 years and over in Thailand. Being female, 50 years or older, married, and Christian; living with a relative; smoking; using opium; and having moderate and high stress levels were associated with depression. Conclusion:Effective public health interventions should be considered to reduce the burden of depression in the hill tribe population by focusing on individuals who are female, 50 years or older, married, Christian, and stressed and those who abuse substances.
