The challenges and potential solutions of achieving meaningful consent amongst research participants in northern Thailand: a qualitative study

BACKGROUND

Achieving meaningful consent can be challenging, particularly in contexts of diminished literacy, yet is a vital part of participant protection in global health research.

METHOD

We explored the challenges and potential solutions of achieving meaningful consent through a qualitative study in a predominantly hill tribe ethnic minority population in northern Thailand, a culturally distinctive population with low literacy. Semi-structured interviews were conducted with 37 respondents who had participated in scrub typhus clinical research, their family members, researchers and other key informants. A thematic analysis was conducted.

RESULTS

Our analysis identified four interrelated themes surrounding participants' ability to give consent: varying degrees of research understanding, limitations of using informal translators, issues impacting decisions to join research, and voluntariness of consent. Suggestions for achieving more meaningful consent included the use of formal translators and community engagement with research populations.

CONCLUSIONS

Participant's agency in decision making to join research should be supported, but research information needs to be communicated to potential participants in a way that they can understand. We found that improved understanding about the study and its potential benefits and harms goes beyond literacy or translation and requires attention to social and cultural factors.

Prevalence of and factors associated with scrub typhus exposure among the hill tribe population living in high incidence areas in Thailand: a cross-sectional study

BACKGROUND

Scrub typhus is a significant tropical disease, occurring in rural settings and therefore usually afflicting remote agricultural populations who have lower socioeconomic status and limited access to medical care. A large proportion of the hill tribe people in Thailand are financially poor, have limited education, and do not have adequate health care access. This study aimed to estimate the prevalence of and determine factors associated with scrub typhus exposure among the hill tribe population living in high-incidence areas in northern Thailand.

METHODS

A cross-sectional study design was used to gather information from hill tribe people aged 18 years and over living in ten hill tribe villages in Mae Fah Luang, Chiang Rai Province, Thailand. Participants who met the inclusion criteria were invited to participate in the study. A validated questionnaire was used as the research instrument, and 5 mL blood samples were taken. Orientia tsutsugamushi IgM and IgG antibodies were detected by enzyme-linked immunosorbent assay (ELISA) and then confirmed by immunofluorescence assay (IFA). Logistic regression was used to detect associations between variables at a significance level of α = 0.05.

RESULTS

A total of 485 hill tribe people participated in the study; 57.1% were female, 29.9% were over 60 years of age, 46.4% were from the Akha tribe, and 74.2% had never attended school. The overall prevalence of scrub typhus exposure was 48.0%. In the multivariate model, five variables were found to be associated with scrub typhus exposure. Participants aged over 60 years had a 4.31-fold increased risk (95% CI = 1.73-10.72) of scrub typhus exposure compared to those who were younger than 30 years. Those who were illiterate had a 3.46-fold increased risk (95% CI = 1.93-6.21) of scrub typhus exposure than those who had at least a primary education level. Participants from the Akha tribe had a 2.20-fold increased risk (95% CI = 1.31-3.72) of scrub typhus exposure than those from the Lahu tribe. Subjects who had a history of cutting grass had a 1.85-fold increased risk (95% CI = 1.20-2.84) of scrub typhus exposure. Those who never wore gloves for farming had a 2.12-fold increased risk (95% CI = 1.28-3.49) of scrub typhus exposure than those who wore gloves daily.

CONCLUSIONS

There is a high prevalence of scrub typhus exposure among the hill tribe in Thailand. Effective public health interventions to promote scrub typhus awareness and prevention are urgently needed in these populations.

Women oppressed in the daily lives and cultural practices of the akha people, Thailand: how can the situation change?

BACKGROUND

Gender equality is one of the most concerning issues globally. Females lacking equality could lead to several impacts, including health and economic impacts. Gender equality is often present in some minorities, such as the Akha hill tribe people who live in remote areas and have poor educational and economic statuses. This study aimed to understand the patterns and forms of women's oppression through their norms and cultures.

METHODS

A qualitative method was used to elicit information from participants in twelve group discussions. The participants were Pha Mee and Ulau Akha people living in six selected villages along the border of Thailand and Myanmar. Twenty-two main questions were used as a guide in the discussions, which were grouped by gender and conducted by a same-gender moderator. The findings were extracted and formed according to a thematic approach.

RESULTS

A total of 72 Akha from six villages were invited to participate in the study: 29 males and 43 females. The average age was 47.7 years, 69.4% were married, 63.8% were Buddhist, 47.2% had never attended a school, and 47.2% worked in the agricultural sector. Several forms of Akha women's oppression were identified: oppression through daily life, religious rituals, son preference, novels and cradle songs, naming ceremonies, and work performances. Many factors acted as unorthodox patterns to relieve the oppression of Akha women: religious conversion, educational impact, exposure to people from outside villages, and social and economic roles. Oppressed Akha women moved through four layers: individual, family, community, and external culture and modernization. The combination of culture and globalization was a key factor in gender inequity through these four layers to balance the pressures to oppress and resist.

CONCLUSIONS

Akha women have lived under the power of men for several years, and these men have built up common features to control women in their society. Improving gender inequity is important for moving to a better stage of health, quality of life, and social roles, which will increase the power of all people to improve their society in the future.

Epidemiology of and Factors Associated with Prehypertension Among Hill Tribe Adults Aged 30-59 Years in Thailand: A Cross-Sectional Study

The study aimed to estimate the prevalence of and to determine the factors associated with prehypertension among the hill tribe aged 30-59 years. A cross-sectional study was conducted to collect data using a validated questionnaire and 5 mL blood specimens among six main hill tribe people living in 30 villages. Logistic regression was used to assess the associations between variables at a significance level of α = 0.05. A total of 1,076 individuals were recruited into the study: 67.3% were females, and 22.6% were aged 30-39 years. The overall prevalence was 67.8%. Six variables were found to be associated with prehypertension: being female; had family members ≤ 4 people; being members of Lahu, Hmong, Yao, Karen, and Lisu; had family debt; had overweight; and had a high total cholesterol. The implementation focused on encouraging active physical activity to reduce prehypertension is serious concerned and introduced.

Influences and patterns of intimate partner violence among married Akha and Lahu women in northern Thailand

BACKGROUND

Intimate partner violence (IPV) is a major global public health problem. Women are the principal victims of IPV, and some special populations have been particularly impacted. The Akha and Lahu women are vulnerable populations for IPV due to the modernization and changes of their culture and norms. This study aimed to understand premarriage factors related to IPV, including associated factors, influencers, patterns and impacts, in Akha and Lahu women in Thailand.

METHODS

A qualitative method was used to gather information among Akha and Lahu women who had experienced IPV in the previous year and were fluent in Thai. Women who had experienced IPV in the previous year and lived in the border area of Thailand and Myanmar were invited to provide information. A thematic analysis was used to extract information from the participants and develop findings.

RESULTS

A total of fifty-two married women were recruited into the study: 46.2% were Akha and 53.8% were Lahu. Those married Akha and Lahu women younger than 39 years found their partner through social media, had conditions before getting married, had high self-confidence, and tended to marry people from different tribes. While those aged 40 years and over met their husbands in village activities, were highly compliant with the norms of their culture, and married men from the same tribe. Three factors were detected as associated factors of IPV: cultural differences between partners from different tribes, substance use, and personality. Differences in age between partners, living in poor family economic status, and poor education were also detected as influencers of IPV. Four patterns of IPV were observed among Akha and Lahu married women: neglect, emotional abuse, verbal abuse, and physical abuse. Several patterns of the impacts were presented: children were neglected, especially in the preparation of daily food, having stress, having poor family relationships, and having children with unsuccessful lives in terms of education and getting a good job. Almost all married Akha and Lahu women had no particular expectations in their lives.

CONCLUSION

Akha and Lahu women face IPV problems with several key influences and impacts. Effective implementations are required to monitor and reduce the problem in the Akha and Lahu families, especially where the women are younger than 40 years old and married to men from different tribes.

Components of stigma and its impact on maternal and child health service and outcomes: perspective of Akha hill tribe women in Thailand

BACKGROUND

Maternal and child health (MCH) is crucial to the well-being of mothers and children. Stigma regarding access to MCH services is a major challenge, especially for hill tribe people in Thailand. The study aimed to understand the components of stigma and its impact on MCH service and outcomes including experiences and expectations to address the stigma in perspective of Akha hill tribe women in Thailand.

METHODS

A phenomenological qualitative approach was used to gather information from Akha women who had attended MCH service one year prior and had an experience with stigma. A validated question guide was used in the study. The interview was conducted in private and confidential rooms in the Akha hill tribe villages between June and September 2021. A thematic analysis was used to extract the major and minor themes and develop the findings.

RESULTS

A total of 61 Akha postdelivery participants were recruited to provide information; the average age was 28.9 years, 32.8% had no Thai ID card, and 93.4% were married. Language, traditional clothing, poverty, and name were identified as drivers of stigma, while health care providers' background, gender differences between clients and health care providers, and knowledge gaps facilitated the stigma. Being a member of a hill tribe acted as the stigma marker. Stigma manifestation was presented in the forms of verbal or physical abuse, refusal to provide treatment, and intentional disclosure of personal information to the public. Accepting the situation with no better option, defending oneself to receive better care and services, and using a private care service were experiences in addressing the stigma. Gender matching, active MCH service, mobile emergency clinics, and appropriate, permanent medical equipment in health care facilities located in their villages were the expectations.

CONCLUSION

Akha women face a variety of stigmas in access to MCH services, with substantial impacts on health outcomes, especially the rate of services in women and child health. Creating laws to prevent the occurrence of any forms of stigma and implementing gender matching in MCH services should be considered.

Quality of sources of drinking water and health among the hill tribe people of northern Thailand

Poor-quality drinking water can cause numerous health problems, particularly for people who are living with poor economic conditions, have a low educational status and have limited access to safe drinking water, such as the hill tribe people in Thailand. This study aimed to assess the quality of different sources of natural drinking water from the hill tribe villages in northern Thailand. Seventy-two drinking water samples from the hill tribe villages were collected and tested for biological, chemical and physical qualities, which were compared with the standard parameter values for safe drinking water according to the World Health Organization. Total coliform bacteria and fecal coliform bacteria, which represented the biological parameters, were detected in all samples. The physical parameters, which consisted of turbidity (36.1%), iron content (5.5%), color (2.7%) and pH (2.7%), exceeded the standard indications. However, the hazard quotient and hazard index values were less than 1. The hill tribe people are facing the problem of poor-quality drinking water, particularly in terms of biological and physical parameters that exceed the standard values. An effective program for improving access to safe water for the hill tribe people should be developed and implemented immediately.

Vaccine serocoverage under the expanded program on immunization among hill tribe children in Thailand: A cross-sectional study

BACKGROUND

Expanded programs on immunization (EPIs) are country-specific vaccine programs designed and implemented to prevent childhood diseases globally, including in Thailand. Hill tribe children in Thailand live in remote areas with underdeveloped education systems and low economic status. This study aimed to assess serocoverage under the EPI and access to vaccination clinics.

METHODS

A cross-sectional study was performed to assess serocoverage after childhood vaccination among hill tribe children who lived in 34 selected villages in Chiang Rai Province, Thailand. A validated questionnaire was administered, and 3-mL blood specimens were collected. Antibodies against hepatitis B surface antigen (anti-HBs), hepatitis B core antigen (anti-HBc), measles, Japanese encephalitis virus (JEV), and tetanus were detected. Chi-square tests were performed to detect the different proportion of patients with antibodies with different characteristics.

RESULTS

Half of the hill tribe children aged 1-18 years did not have medical evidence (logbook) of immunization. More than 98.0% of the children who had medical evidence received the recommended immunizations. Only half of the children had anti-HBs (51.1%), and 22.3% had antibodies against JEV. The majority were found to be positive for antibodies against measles (83.3%) and tetanus (91.4%). Sex (p-value = 0.028), tribe (p-value < 0.001), age (p-value < 0.001), and parents' monthly income (p-value = 0.008) were associated with a lack of medical evidence.

CONCLUSIONS

Existing immunization programs for hill tribe children in Thailand should be urgently evaluated and monitored for effectiveness.

Association Between Lifestyle Behaviors and Hypertension Among Hill Tribe Adults in Thailand: a Cross-Sectional Study

BACKGROUND

Hypertension (HT) is a serious problem in the adult population, particularly among individuals who are living in poor economic conditions and have a low education level. This study aimed to determine the associations between lifestyle and HT among adult hill tribe populations in Thailand.

METHODS

A cross-sectional study was conducted to gather information on several risk behaviors related to HT among the hill tribe population aged 30 years and older by using a validated questionnaire and 5 mL blood specimens. The study was conducted in 30 selected hill tribe villages in Chiang Rai Province, Northern Thailand. Logistic regression was used to detect the associations.

RESULTS

A total of 2552 participants participated in the project; 65.9% were female, 72.4% were aged 40-69 years, and 54.2% were Buddhist. The overall prevalence of HT was 33.7%. After controlling for all potential confounding variables, two variables were found to be associated with HT: participants who used moderate (AOR=1.57; 95% CI=1.03-3.76) and high amounts (AOR=1.59; 95% CI=1.05-3.78) of oil for cooking had greater odds of having HT than those who used small amounts. Those who had low (AOR=1.45; 95% CI=1.13-1.88), moderate (AOR=2.68; 95% CI=1.80-8.78), and high (AOR=1.61; 95% CI=1.36-7.26) levels of depression had greater odds of having HT than those who were not depressed.

CONCLUSIONS

Effective public health programs that focus on reducing the use of daily oil for cooking and decreasing the prevalence of depression in hill tribe people are urgently needed.

Experiences and expectations regarding COVID-19 prevention and control measures among the hill tribe population of northern Thailand: a qualitative study

Background

COVID-19 has been a major human threat for a year. A large number of people have been infected and killed globally, including hill tribe people living in remote and border areas between Thailand and Myanmar. Different expectations of and experiences with the implemented disease prevention and control measures by local, national and international organizations have been widely reported. This study aimed to understand the experiences and expectations regarding the disease prevention and control measures that were implemented among hill tribe people in Thailand.

Methods

Qualitative data were collected from participants aged 20 and older who belonged to the hill tribes living on the border of northern Thailand and Myanmar. A semistructured questionnaire was used to guide interviews. Information was extracted for thematic analysis by the NVivo program.

Results

Fifty-seven participants (36 female, 21 male) were interviewed; 27 participants were Thai Yai, 14 participants were Yunnan Chinese, 8 participants were Akha, and 8 participants were from other tribes. The average age was 45.8 years (min = 20 years, max = 90 years). Thirty participants had never attended school, and the other 27 participants had received education at different levels, from primary school to higher education. Forty participants were unemployed, 13 worked as agriculturists, and the other 4 were attending school. Both positive experiences, such as improving personal hygiene practices, maintaining close contact and increasing relationships among family members and demonstrating the leadership of the villager leaders, and negative experiences, including interruption of social interactions, family financial problems, poor access to medical care services, and invisible people to the government, were found. Different expectations were observed regarding organizations at the local, national, and international levels. Expectations at the local level included villagers and community leaders taking action to strongly contribute to prevention and control measures and to prevent unscreened people from entering the village. Obtaining accurate information about the disease and being financially supported were expectations at the national level, while closing borders to protect cases from overflowing into their villages was an international-level expectation.

Conclusion

Although hill tribes reside in very remote rural areas, they experience both positive and negative effects of the disease prevention and control measures implemented by organizations. Their expectations are formally and informally voiced to policy makers at the local, national and international levels.

Antibiotic resistance among the Lahu hill tribe people, northern Thailand: a cross-sectional study

BACKGROUND

Antibiotic resistance is often reported and great concerned as one of public health problems especially people living with poverty in developing countries including Thailand. The hill tribe people is defined as vulnerable population for antibiotic resistance in Thailand due to poor economic and education status particularly the Lahu people who is the second greatest group of the hill tribe people in Thailand. The study aimed to estimate the prevalence, factors associated with, and typing major species of bacteria with antibiotic drugs resistance among the Lahu hill tribe people in northern Thailand.

METHODS

A cross-sectional study was conducted to gather the information from the participants. A validated questionnaire was used for data collection. Participants who presented an illness related to infectious diseases were eligible to participate the study and were asked to obtain specific specimen; sputum, urine or stool. Antibiotic susceptibility was tested by Kirbey Bauer's disc diffusion test. Chi-square and logistic regression were used to detect the associations between variables at the significant level of α = 0.05.

RESULTS

A total of 240 participants were recruited into the study. The majority had urinary tract infection (67.9%) with two major pathogenic species of the infection; Escherichia coli (12.8%), and Enterobacter cloacae (8.0%). The prevalence of antibiotic resistance was 16.0%. Escherichia coli and Klebsiella pneumoniae species were found to have multidrug resistance that was greater than that of other species, while ampicillin was found to have the greatest drug resistance. It was found that those who had poor knowledge of antibiotic use had a 2.56-fold greater chance (95% CI = 1.09-5.32) of having antibiotic resistance than did those who had good knowledge of antibiotic use, and those who had poor antibiotic use behaviors had a 1.79-fold greater chance (95% CI = 1.06-4.80) of having antibiotic resistance than did those who had good antibiotic use behaviors.

CONCLUSION

Effective public health interventions are urgently needed to reduce antibiotic drug resistance among the Lahu people by improving their knowledge and skills regarding the proper use of antibiotics and eventually minimizing antibiotic resistance. Moreover, health care professionals should strictly follow the standard guideline to prescribe antibiotics.

Factors associated with hypertriglyceridemia among the hill tribe people aged 30 years and over, Thailand: a cross-sectional study

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.

Factors associated with elevated low-density lipoprotein cholesterol levels among hill tribe people aged 30 years and over in Thailand: a cross-sectional study

Background

Low-density lipoprotein cholesterol (LDL-C) is one of the most important types of cholesterol and has an impact on health. Certain lifestyle and dietary habits in different populations may leads to increased levels of LDL-C, particularly among those with poor education and economic statuses, such as hill tribe people in Thailand. This study aimed to estimate the prevalence of and determine the factors associated with high LDL-C levels among hill tribe people in northern Thailand.

Methods

A cross-sectional study was performed to gather information from six main hill tribe populations: Akha, Lahu, Hmong, Yao, Karen, and Lisu. Individuals who were aged over 30 years and living in 30 selected hill tribe villages were invited to participate in the study. A validated questionnaire and 5-mL blood specimens were used to obtain data. Correlation analyses, chi-square tests, t-tests, and logistic regression were used to detect correlations and associations.

Results

A total of 2552 participants were recruited into the study; 65.9% were females, and 64.1% were aged younger than 60 years old. Approximately 69.6% of participants had abnormal LDL-C levels; 33.6% had above-optimal levels, 24.3% had borderline high levels, 8.0% had high levels, and 3.7% had very high levels. A total of 17.4% of participants had low high-density lipoprotein cholesterol (HDL-C) and high LDL-C levels, while 14.9% had high triglyceride and LDL-C levels. After controlling for sex, age, religion, education, annual family income, and marital status in the multivariate model, three variables were found to be associated with high LDL-C levels: occupation, the amount of lard used in daily cooking, and glycated hemoglobin (HbA1c). Those who were working as agriculturalists had a 1.34-fold greater chance of having abnormal LDL-C than traders and others (95% CI = 1.09–1.34). Those who used moderate and high quantities of lard in their daily cooking had a 1.45-fold (95% CI = 1.15–1.82) and 1.31-fold (95% CI = 1.04–1.68) greater likelihood of having abnormal LDL-C levels than those who used low quantities, respectively. Those who had abnormal HbA1c levels were less likely to develop abnormal LDL-C levels than those who had normal HbA1c levels (AOR = 0.69, 95% CI = 0.51–92).

Conclusions

Effective public health programs that do not conflict with the cultures of hill tribes are urgently needed, particularly programs encouraging the use of small quantities of lard for daily cooking practices.

Pulmonary function and factors associated with current smoking among the hill tribe populations in northern Thailand: a cross-sectional study

Background

Smoking is considered one of the major poor health behaviors leading to several health problems. Individuals with a poor education and economic status are vulnerable to smoking, particularly the hill tribe people in Thailand. This study aimed to estimate the prevalence of current smoking, assess pulmonary function, and identify factors associated with current smoking among individuals aged 20 years and older of the hill tribes in northern Thailand.

Method

A cross-sectional study was conducted to gather information from the hill tribe people living in 42 hill tribe villages. A validated questionnaire, spirometry, and pulse oximetry were used as the research tools. Face-to-face interviews were conducted to collect data from the participants in a private room after obtaining informed consent voluntarily. Chi-squared test and logistic regression were used to detect the associations between the variables at the significance level of α = 0.05.

Results

In total, 2216 participants were recruited into the study: 54.6% were women, 80.3% were aged 31–59 years, and 86.1% were married. The prevalence of smoking was 36.3%; 20.6% were current smokers (36.7% among men and 7.0% among women), and 15.7% were ever smokers. Half of the participants (50.1%) had smoked for ≤9 years, 80.1% smoked ≤10 pieces per day, 64.2% smoked traditional tobacco, 42.8% had low-to-moderate levels of knowledge of the harms of smoking, and 68.4% had low-to-moderate levels of attitudes toward the harms of smoking. Only sex was statistically significant among the different smoking behaviors (p-value< 0.001), and the participants’ pulmonary function was not significantly different. After controlling for age, sex, religion, and education, three variables were found to be associated with current smoking among the hill tribe people in Thailand: men were more likely to smoke than women (AOR = 7.52, 95% CI = 5.53–10.24); those who used amphetamines were more likely to smoke than those who did not (AOR = 2.92, 95% CI = 1.69–5.03); those who had poor attitudes toward the harms of smoking were more likely to smoke than those who had a positive attitude toward the harms of smoking (AOR = 2.47, 95% CI = 1.53–3.97).

Conclusion

Translating essential health messages into the hill tribe language and improving the channel to deliver this information to the target populations, particularly men, are crucial strategies for improving their knowledge and attitudes toward the harms of smoking and making them quit smoking.

Seroprevalence and factors associated with hepatitis B infection among the hill tribe adult population in Thailand: a cross-sectional study

Background

Hepatitis B virus (HBV) infection is one of the greatest public health burdens, particularly for people living with several barriers to access to health care services, such as the hill tribe adult population in Thailand. People aged 25 years and over who are out of the target population for HBV immunization under the national Expanded Program on Immunization (EPI) are at risk of HBV infection. The study aimed to estimate the prevalence and determine the factors associated with HBV infection among hill tribe adults aged 25 years and over living in Chiang Rai Province, Thailand.

Methods

A cross-sectional study design was used to collect information on hill tribe adults aged 25 years and over living in 36 selected hill tribe villages in Chiang Rai Province. All people living in the selected villages who met the criteria were invited to participate in the study. A validated questionnaire and a 5-mL blood specimen were used as research instruments. Hepatitis B surface antigen (HBsAg), antibody to hepatitis B surface (anti-HBs), and antibody to hepatitis B core (anti-HBc) were detected by using the Wondfo Test Kit^@, which has high sensitivity and specificity. Logistic regression was used to detect the associations between variables at the significance level of α = 0.05.

Results

A total of 1491 individuals were recruited into the analysis; 60.8% were females, 81.3% were aged between 30 and 60 years, and 86.0% were married. The majority were illiterate (54.9%), were Buddhist (55.7%), worked in agricultural sectors (87.3%), and had an annual income of less than 50,000 baht per year (72.9%). The overall prevalence of hepatitis B infection was 26.6%; 7.6% were positive for HBsAg, 19.2% were positive for anti-HBs, and 18.9% were positive for anti-HBc. In the multivariate analysis, three variables were found to be associated with hepatitis B infection: those who were in the Yao and Lisu tribes had a 1.64-fold (95% CI = 1.08–2.49) and a 1.93-fold (95% CI = 1.10–3.31) greater chance, respectively, of HBV infection than did those in the Karen tribe; those who were Christian had a 1.41-fold (95% CI = 1.06–1.87) greater chance of HBV infection than did those who were Buddhist; and those who did not use alcohol had a 1.29-fold (95% CI = 1.01–1.65) greater chance of HBV infection than did those who used alcohol.

Conclusions

It is necessary to develop and implement effective public health interventions among hill tribe adult populations who are not part of the EPI-targeted population, particularly Christians, those in the Lisu and Yao tribes, and those who do not use alcohol, to reduce the HBV infection rate, save lives and reduce medical expenses.

Prevalence of and factors associated with depression among hill tribe individuals aged 30 years and over in Thailand

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 = 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.

Sexual behaviors and seroprevalence of HIV, HBV, and HCV among hill tribe youths of Northern Thailand

Background

Sexual behaviors reflect the degree of exposure to human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV), especially in people in sexually active stages, such as youths. Hill tribe people have their own cultures, beliefs and lifestyles related to their behaviors, including sexual behaviors, which may lead to HIV, HBV, and HCV infections, especially among youths. The study aimed to examine sexual behaviors and assess the seroprevalence of HIV, HBV, and HCV among hill tribe youths.

Methods

A cross-sectional study was conducted. The participants were recruited from 60 randomly selected hill tribe villages in Chiang Rai Province, Thailand. A validated questionnaire and 5 mL blood specimens were used to collect data. Data were collected by a self-reporting method. Rapid immunochromatographic tests were used to detect hepatitis B surface antibody (anti-HBs), hepatitis B surface antigen (HBsAg), hepatitis C antibody (anti-HCV), and human immunodeficiency virus antibody-I and- II (anti-HIV-1 and -2). Chi-square and Fisher’s exact test were used to detect the associations between variables.

Results

A total of 1325 participants were recruited for the analysis. The majority were females (60.5%) and aged 15–17 years (58.9%). A total of 14.5% smoked, 22.4% drank alcohol, 14.2% were tattooed, and 61.4% had their ears pierced. Among the 30.3% who had sexual experience, 42.0% experienced one-night stands, 26.9% had sexual contact with a prostitute within 1 year prior to the study, 18.9% used alcohol prior to having sexual intercourse, and 15.7% had been tested for HIV/AIDS previously. Among males, 11.5% were males who had sex with males (MSM), and 4.6% were bisexual. Among females, 83.0% were females who had sex with males, and 5.0% were females who had sex with females. Different sexes and tribes were found to have significantly different risk behaviors and sexual behaviors, such as overall males having a greater proportion of sexual experience than females, and Lahu, Akha and Hmong had a higher proportion of sexual experience, having sexual experience with one-night stands, and having sexual experience with a prostitute 1 year prior to the study than others. Among the 836 obtained blood samples, none were positive for anti-HIV-I and -II, 6.4% were positive for anti-HBs, 1.9% were positive for HBsAg, and 0.2% were positive for anti-HCV.

Conclusion

Hill tribe youths in Thailand are at risk of STIs such as HBV and HCV infections according to their risk behaviors and sexual behaviors, which differ between sexes and tribes. Effective behavioral interventions should be promoted among hill tribe youths to minimize the risk for these diseases in the future.

Perceived factors influencing the initiation of methamphetamine use among Akha and Lahu youths: a qualitative approach

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.

Food Consumption and Accessibility in Hill Tribe and Urban Women, Chiang Rai Province, Northern Thailand

This analytical cross-sectional study aimed to examine the associations between setting and food consumption and accessibility in two districts of Chiang Rai province, northern Thailand. 128 women (65 in hill tribe setting and 63 in urban setting) were surveyed using an interviewer-administered questionnaire. Traditional and mobile markets were well utilized in both settings, in spite of the growth of multinational retailers. Consumption of ready-to-eat food and home-grown/reared or wild foods was associated with socioeconomic status. Fewer hill tribe women had eaten ready-to-eat food, although some reported fairly regular consumption. Consumption of home-grown/reared or wild foods was more evident in the hill tribe group, showing their continued utilization of traditional food resources.

Seroprevalence and factors associated with hepatitis B virus infection among the hill tribe youths, northern Thailand

Background

Hepatitis B virus (HBV) infection is a major viral infection, particularly in people living in the Western Pacific region, including the hill tribe people living in northern Thailand. This study aimed to estimate the prevalence of HBV infection and to detect the factors associated with HBV infection among hill tribe youths in Thailand.

Methods

A cross-sectional study was conducted to estimate the prevalence and determine the factors associated with HBV infection among hill tribe youths living in northern Thailand. A validated questionnaire and 5 mL blood sample were used for data collection. The Wondfo Diagnostic Kit®, the Wondfo One Step HBsAg Serum/Plasma Test®, and the Wondfo One Step HBsAg Serum/Plasma Test® were used for anti-HBsAg, HBsAg, and total anti-HBc detections, respectively. Logistic regression was used to detect associations between variables with an α = 0.05 significance level.

Results

A total of 836 participants were included in the study; 62.7% were female, 58.9% were aged 15–17 years, 58.7% were Buddhist, 78.4% graduated high school, and 89.1% had no income. The majority were Akha (30.0%), Yao (16.3%), and Hmong (15.8%); 13.2% smoked, 21.5% used alcohol, 13.3% had tattoos, 3.9% experienced drug injection from illegal practitioners, and 35.7% had no history of HBV immunization. The prevalence of HBsAg was 3.0%; anti-HBs, 10.2%; and total anti-HBc, 8.1%. In the multivariate analysis, four variables were found to be significantly associated with HBV infection among the hill tribe youths: age, tribe, work experience, and number of partners. Those aged 18–20 years and 21–24 years had 2.13 times (95%CI = 1.35–3.29) and 2.39 times (95%CI = 1.05–3.90) greater odds of HBV infection, respectively, than those aged 15–17 years. Akha, Lahu, and Hmong youths had 3.12 times (95%CI = 1.07–9.12), 3.71 times (95%CI = 1.21–11.41), and 3.84 times (95%CI = 1.26–11.69) greater odds of HBV infection, respectively, than Lisu youths. Those who had experience working outside of the village had a 1.77 times (95%CI = 1.18–2.98) greater chance of HBV infection than those who did not have experience working outside of the village, and those who had ≥2 partners had a 2.66 times (95%CI = 1.96–3.87) greater chance of HBV infection than those who had no partner.

Conclusions

Effective HBV prevention programs should be promoted in Akha, Lahu, and Hmong youth populations, particularly to those who have sexual partners, work outside of the village and are aged 18–24 years.

Prevalence and factors associated with type 2 diabetes mellitus and hypertension among the hill tribe elderly populations in northern Thailand

BACKGROUND

Type 2 diabetes mellitus (T2DM) and hypertension (HT) are major noncommunicable health problems in both developing and developed countries, including Thailand. Each year, a large amount of money is budgeted for treatment and care. Hill tribe people are a marginalized population in Thailand, and members of its elderly population are vulnerable to health problems due to language barriers, lifestyles, and daily dietary intake.

METHODS

An analytic cross-sectional study was conducted to estimate the prevalence of T2DM and HT and to assess the factors associated with T2DM and HT. The study populations were hill tribe elderly adults aged ≥  60 years living in Chiang Rai Province, Thailand. A simple random method was used to select the targeted hill tribe villages and participants into the study. A validated questionnaire, physical examination form, and 5-mL blood specimen were used as research instruments. Fasting plasma glucose and blood pressure were examined and used as outcome measurements. Chi-square tests and logistic regression were used for detecting the associations between variables at the significance level alpha=0.05.

RESULTS

In total, 793 participants participated in the study; 49.6% were male, and 51.7% were aged 60-69 years. A total of 71.5% were Buddhist, 93.8% were uneducated, 62.9% were unemployed, and 89 % earned an income of < 5,000 baht/month. The overall prevalence of T2DM and HT was 16.8% and 45.5%, respectively. Approximately 9.0% individuals had comorbidity of T2DM and HT. Members of the Lahu, Yao, Karen, and Lisu tribes had a greater odds of developing T2DM than did those of the Akha tribe. Being overweight, having a parental history of T2DM, and having high cholesterol were associated with T2DM development. In contrast, those who engaged in highly physical activities and exercise had lower odds of developing T2DM than did those who did not. Regarding HT, being female, having a high dietary salt intake, being overweight, and having a parental history of HT were associated with HT development among the hill tribe elderly populations.

CONCLUSIONS

The prevalence of T2DH and HT among the hill tribe elderly populations is higher than that among the general Thai population. Public health interventions should focus on encouraging physical activity and reducing personal weight, dietary salt intake, and greasy food consumption among the hill tribe elderly.
