ABSTRACT

A high prevalence of depression has been detected among individuals from the hill tribes in Thailand. However, there are no proper interventions to address this problem. Using a community-based participatory research (CBPR) design, the study team developed a model of depression care for this population. The study involved 45 people in the model development and 65 people in the model testing, who were patients, family members, village health volunteers (VHVs), community and religious leaders, healthcare personnel, NGOs, and local administrative staff. The model development was divided into three phases: understanding the current situation of depression and care, model development, and evaluation of its effectiveness using psychological and relevant outcomes. Questionnaires, observations, focus groups, and in-depth interviews were used for data collection, and content analysis was employed for qualitative data. The Wilcoxon signed-rank test was used to analyze changes in VHVs' knowledge and skills before and after training. The resulting model, "SMILE," consists of stakeholders' readiness (S), external and internal motivations (M), interpersonal relationship (I), life and community assets (L), and empowerment (E). VHVs underwent training on the model, and after training, their knowledge increased significantly from 3.50 ± 1.14 to 8.28 ± 0.81 (p < 0.001). Moreover, their basic counselling and depression screening skills showed improvement from 3.39 ± 1.23 to 7.64 ± 3.76 (p < 0.001). The developed model can be applied to other hill tribe communities in Northern Thailand to improve depression care.

ABSTRACT

BACKGROUND: Even though, there is a particularly high prevalence of depression among individuals from the hill tribes in northern Thailand, they are unable to receive appropriate intervention due to cultural, transportation, communication, and legal barriers. Using community-based participatory research (CBPR), a depression care model was developed for the hill tribe population. The effectiveness of this model was examined using questionnaires, observations, focus groups, and in-depth interviews. METHODS: Participants include people with depression (n = 17) who were chosen based on their mild to moderately severe depression scores on the Patient Health Questionnaire 9-item (PHQ-9 scores of 5-19) and their caregivers (n = 5). The in-depth interview was conducted to distinguish the selected participants into two groups. The first group, the self-help group program, consisted of 12 participants endorsing negative thoughts about themselves and inappropriate problems solving. The second group, the family camp program, had ten participants, including five patients with family-related issues and their family members. Subjects separately participated in either the self-help or the family groups over three weeks. They completed the PHQ-9 at the beginning and end of the intervention. Questionnaires, observations, focus groups, and in-depth interviews were used to evaluate the effectiveness of the model. Content analysis was used to examine the qualitative data. Wilcoxon signed-rank test was used to analyze the changes in the severity of depression before and after participation in the intervention. RESULTS: The depression scores on the PHQ-9 of 12 participants improved significantly (11.92 ± 1.08 vs. 3.08 ± 0.51; p = 0.002) following participation in the self-help group. Increased self-esteem and improved interpersonal relationships were reported by participants in the self-help group program during interviews. There was no significant difference in the depression scores of 10 participating in the family camp program (6.00 ± 3.83 to 5.30 ± 3.56; p = 0.161). CONCLUSION: A model for depression care was tested in a hill tribe community, and its effectiveness was clearly observed. The developed model can be applied to other hill tribe communities in northern Thailand to improve depression care.

ABSTRACT

BACKGROUND: Domestic violence is one of the largest silent problems in the world. Women, children, and elderly individuals often fall victims to family members who use alcohol. However, there is lack of scientific evidence on alcohol consumption and domestic violence among Lahu hill tribe families. OBJECTIVES: The objective of this study was to investigate the prevalence of family violence, violence against women, and alcohol-related harm to children and elderly individuals and to determine the correlations between alcohol consumption and family violence among Lahu tribe families in northern Thailand. METHOD: A cross-sectional study was applied to collect data from participants living in 10 randomly selected villages from the list of Lahu villages in Chiang Rai Province, Thailand. A validated questionnaire and the Alcohol Use Disorders Identification Test were used to collect information from the participants in private and confidential rooms at a community hall between March and August 2019. Data were described and tested for correlation at the significance levels of α = 0.05 and 0.01. FINDINGS: A total of 350 of 719 recruited Lahu families participated in the study (response rate = 48.7%). Among female participants, 22.3% reported history of sexual harassment and 4.1% had been forced to have sex. Children and elderly individuals reported several experiences with people who had used alcohol in the past year; 6.4% had been left to live alone, 5.0% experienced financial neglect, and 1.8% had been neglected while sick. In a correlation analysis, it was found that age (r = -0.02, p value < 0.009), education (r = 0.15, p value < 0.047), marital status (r = 0.25, p value < 0.001), and religion (r = 0.20, p value < 0.008) were significantly correlated with verbal arguments among family members. Experience of sexual harassment was correlated with the presence of a drinker in the family (r = 0.22, p value < 0.001). CONCLUSION: Government and relevant agencies should cooperate to reduce the consumption of alcohol among Lahu men. Moreover, a specific training program to personally improve one's skill in responding to domestic violence among children, women, and elderly individuals should also be developed and implemented in Lahu communities.

ABSTRACT

BACKGROUND: Depression is globally recognized as a major mental health problem in all age categories, particularly among those living in poor economic conditions and with low levels of education, including the hill tribe people in northern Thailand. METHODS: This cross-sectional study aimed to estimate the prevalence of depression and determine the factors associated with depression in the hill tribe population aged 40 and over in northern Thailand. Hill tribe people who lived in the selected villages and met the inclusion criteria were invited to participate in the study. A validated questionnaire and the Patient Health Questionnaire-9 (PHQ-9) were used for data collection. An interview was conducted in a private and confidential room in the selected villages between January and April 2019. Logistic regression was used to determine the factors associated with depression at a significance level of α = 0.05. RESULTS: A total of 601 participants were recruited into the study. More than half (64.23%) were women, 46.76% were Akha, 61.90% were aged 40-59 years, and 76.37% were married. Half of the participants were Christian (57.07%) and had no monthly income (51.25%), and 85% were illiterate. The overall prevalence of depression was 39.10%: 75.74% had mild depression, 17.88% had moderate depression, and 6.38% had severe depression. In the multivariate model, three variables were found to be associated with depression: being female, having a history of substance abuse, and experiencing stress six months prior. Compared to men, women were 2.09 times (95% CI 1.30-3.35) more likely to have depression. Those who had a history of substance abuse were more likely to have depression than those who did not have a history of substance abuse (AOR = 1.97; 95% CI 1.25-3.10). Those who had a history of stress in the prior 6 months were more likely to have depression than those who did not (AOR = 6.43; 95% CI 4.20-9.85). CONCLUSION: Public health screening programs to identify depression in the hill tribe population are urgently needed, particularly for women, those who have abused psychoactive substances, and those who have experienced stress.

ABSTRACT

BACKGROUND: Domestic violence significantly affects physical and mental health, particularly among children, women, and the elderly. Living in certain family environments could lead to victimization by domestic violence, especially among families with a poor socioeconomic status, such as the Lahu hill tribe people in Thailand. This study aimed to estimate the prevalence of and determine the factors associated with domestic violence among Lahu children, women, and the elderly. METHODS: A cross-sectional study was conducted of participants who belonged to the Lahu hill tribe and lived in 20 selected villages in Chiang Rai Province, Thailand. A validated questionnaire was used to collect personal information and information regarding experiences related to domestic violence in the past year from children (aged 5-15 years), women (aged 16-59 years), and the elderly (aged 60 years and over). A binary logistic regression was used to detect associations between the variables. RESULTS: A total of 646 participants were recruited into the study, specifically, 98 children aged 5-15 years, 430 women aged 16-59 years, and 118 elderly people. Children who smoked (AOR = 8.70; 95%CI = 1.27-59.45) had greater odds of experiencing domestic violence than children who did not smoke. Women who had a role as a family member (AOR = 1.59; 95%CI = 1.02-2.50), used alcohol (AOR = 3.36; 95%CI = 2.27-4.99), lived in a family with financial problems (AOR = 4.01; 95%CI = 2.52-7.66), and lived with a family member who uses alcohol (AOR = 2.87; 95%CI = 2.20-5.63) had greater odds of suffering domestic violence than women who did not share these characteristics. The elderly who used alcohol (AOR = 3.25, 95%CI = 1.08-9.81), lived with a family member who uses alcohol (AOR = 3.31; 95%CI = 1.26-7.34), or lived in a family with financial problems in the past year (AOR = 2.16; 95%CI = 1.16-8.77) had greater odds of facing domestic violence than the elderly who did not have these characteristics. CONCLUSION: Family financial problems and substance use are associated with domestic violence in Lahu families in Thailand. Health interventions to reduce the use of substances, including training programs to respond to domestic violence, should be promoted for Lahu children, women, and the elderly.

ABSTRACT

BACKGROUND: Tuberculosis (TB) is a major human threat, as evidenced by the large numbers of cases and deaths, particularly in developing countries with poor economic and educational statuses. Myanmar has one of the highest TB burdens in the world, but no TB information is available for people living in the rural northeastern regions of Myanmar. The present study estimated the prevalence of TB and identified factors associated with TB infection in people living in rural communities in Shan State. METHODS: A cross-sectional study was performed to gather information from participants. People aged 18-59 years who lived in the three areas with the highest numbers of TB cases in Shan State in northeastern Myanmar were included in the study population. A simple random method was used to select the sample from the villages. A validated questionnaire was used for data collection in face-to-face interviews after obtaining signed informed consent from the selected participants. The Mantoux tuberculin skin test (TST) was administered to detect TB infection, and a result that was 10 mm or greater after 48 h was considered positive. Chi-squared tests and logistic regression were used to identify the associations between the variables at a significance level of α = 0.05. RESULTS: A total of 303 participants were recruited for the study; 64.7% were females, and the mean age was 37 years (SD = 12.5). Most participants were Burmese (25.4%), and 14.95% were Shan. Sixty-three participants (20.8%) had a positive TST. Four variables were associated with TB infection in the multivariate model. Males had a greater chance of TB infection than females (AOR = 2.51; 95% CI = 1.32-4.76). Participants who were ever married had a greater chance of TB infection than participants who were single (AOR = 3.93; 95% CI = 1.18-13.00). Participants who used wood and charcoal as their main sources of energy for cooking had a greater chance of TB infection than participants who used electricity (AOR = 4.23; 95% CI = 1.25-9.64). Participants who had a low level of TB prevention and care knowledge had a greater chance of TB infection than participants with a high level of TB prevention and care knowledge (AOR = 4.49; 95% CI = 1.88-10.72). CONCLUSIONS: Public health programs that focus on improving knowledge of TB prevention and care and avoiding the use of wood and charcoal as the primary sources of energy for cooking, particularly in males and ever-married individuals, are urgently needed.

ABSTRACT

BACKGROUND: Alcohol use has impacts on several dimensions of health, including physical health and mental health, particularly in college-age populations. Therefore, this study aimed to estimate the prevalence and to determine factors associated with alcohol use behaviors among college students in Bhutan. METHODS: A cross-sectional design was applied to collect data from the participants. A simple random method was used to select the participants from the lists of students who were attending the four selected colleges in Bhutan in the academic year of 2019. A questionnaire was developed, and validity and reliability were verified before use. Descriptive statistics were applied to describe the general characteristics of participants, while logistic regression was used to detect the associations between variables at the significance level of α = 0.05. RESULTS: A total of 432 college students were recruited into the study, of whom 62.0% were females. The average age was 20.0 years, 40.7% were the third-year students, and 79.9% lived in college dormitories. The prevalence of current drinking was 51.6% and that of binge drinking was 19.4%. After controlling for all potential confounder factors, three variables were found to be associated with current drinking: students who had low income were more likely to be current drinkers than those who had high income (AOR = 2.59, 95% CI = 1.29-5.21); students who did not use tobacco were more likely to be current drinkers than those students who used tobacco (AOR = 6.99, 95% CI = 2.90-16.81); and students who had close friends who did not use alcohol were more likely to be current drinkers than those who had close friends who used alcohol (AOR = 5.14, 95% CI = 3.04-8.69). Four factors were found to be associated with binge drinking after controlling for all possible confounder factors: students who had high income were more likely to be binge drinkers than those who had low income (AOR = 3.03, 95% CI = 1.72-5.31); students who used tobacco were more likely to be binge drinkers than those students who did not use tobacco (AOR = 2.28, 95% CI = 1.35-3.87); students whose parents used alcohol were more likely to be binge drinkers than those students whose parents did not use alcohol (AOR = 1.75, 95% CI = 1.02-3.01); and students whose close friends used alcohol were more likely to be binge drinkers than those who had close friends who did not use alcohol (AOR = 2.26, 95% CI = 1.05-4.87). CONCLUSIONS: There is a high prevalence in alcohol use among the college students in Bhutan. Effective health promotion programs should be implemented by focusing on reducing the alcohol consumption among college students.

ABSTRACT

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 = 1.66-15.32). Those who had been physically assaulted by a family member while aged 0-5 years had a greater chance of MA use than those who had not (AOR = 2.29; 95% CI = 1.02-5.12). Those who had been physically assaulted by a family member while aged 6-14 years had a greater chance of MA use than those who had not (AOR = 3.15; 95% CI = 1.32-7.54). Those who had a close friend who used alcohol had a greater chance of MA use than those who did not (AOR = 2.24; 95% CI = 1.24-4.72). Those who had a highly confident personality had a greater chance of MA use than those who did not (AOR = 2.35; 95% CI = 1.17-4.69), and those who smoked had a greater chance of MA use than those who did not (AOR = 8.27; 95% CI = 4.42-15.46). CONCLUSIONS: All relevant government and nongovernment agencies together with the Ministry of Public Health Thailand should address MA use among Akha and Lahu youths by properly developing a community health intervention that lowers risk of MA use by addressing family relationships, male youth behaviors, and focused on those individuals with a highly confident personality.

ABSTRACT

BACKGROUND: Alcohol 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. METHODS: An 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. RESULTS: A 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). CONCLUSION: To 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.

ABSTRACT

In developing countries family caregivers are an important community-based resource who provide care for physically disabled adults. Substantial caregiving commitment is known to adversely affect caregiver health and thereby their capacity to provide ongoing care. This systematic review focused on support interventions for caregivers using Thailand as an example. From 1964 to 2011 international and Thai electronic databases and relevant grey literature were searched. Six English papers and 34 Thai papers published between 1990 and 2010 were found. The Critical Appraisal Skills Programme (CASP) tool was modified to appraise methodological quality. All nurse-led interventions mainly focused on improving caregiving capacity; nearly half considered caregiver health. Only 15 interventions were community-based. Despite variable research quality all studies showed benefits for caregivers, care recipients, and healthcare services. In developing countries without healthy caregivers physically disabled adults would not receive care. There is an urgent need for further investment in community-based research to develop effective interventions designed to promote caregiver health and help them maintain their role.

ABSTRACT

The purpose of this study was to develop and test the psychometric properties of the Mental Health Assessment Tool for Older Thai Adults (MHAT-T), a 32-item self-report questionnaire. Development of the MHAT-T was based on an exploratory sequential mixed methods design, where the results of the first method (qualitative) were used to develop the mental health assessment tool for older Thai adults. The initial questionnaire was composed of 100 items and carried out among 1,266 older Thai adults (aged 60 years and over), including Buddhists, Muslims, and Catholics in the northeastern, northern, central, and southern Thailand, and the Bangkok Metropolitan Area. The exploratory factor analysis, with an acceptable factor structure model, yielded 32 items aligned with five factors: family attachment, mental quality, community dignity and support, mental status, mental capacity. The preliminary psychometric properties demonstrated the internal consistency of the MHAT-T was at a high range of 0.76 to 0.87 and acceptable for a new instrument. The MHAT-T had an excellent content validity index score of 0.99. Test-retest reliability at two weeks was fair (0.54 to 1.00, p>0.001). A score of 92 of 106 points was classified as normal mental health. The MHAT-T served adequately as a newly captured construct and should be offered as a tool for assessing mental health among older Thai adults in the community.

ABSTRACT

Several researchers have investigated the impact of menopause on American and European women. Yet there is little research that has focused on the meaning of this experience in other cultural and ethnic groups. In Thailand, although there is research concerning the physical symptomotology associated with the postmenopausal period, scant data exists on psychological stress among this cohort. Exercise is important for both stress reduction and health promotion. However, no clear consensus has been reached, suggesting the need for exploration of the relationship between exercise and psychological stress. Our purpose of this study was to examine the effects of exercise on stress in Thai postmenopausal women. A one-group pretest posttest design was utilized. Data were collected on 102 Thai postmenopausal women. The findings suggest that an exercise program may be a safe, simple, and cost beneficial intervention.
