Pesticide-related mental health issues in Thailand, an upper-middle-income country, are not well known. This study aimed to investigate the association between the history of occupational exposure to pesticides and the mental health of Thai farmers. A cross-sectional study was carried out in the areas around Chiang Mai, a large city in Northern Thailand, between June 2020 and January 2021. A total of 6974 farmers from six districts were interviewed to determine whether they regularly experienced symptoms related to mental health by the Self-Reporting Questionnaire (SRQ-20) as well as their lifetime history of agricultural pesticide exposure from 31 active ingredients and five functional categories: insecticides, herbicides, fungicides, rodenticides, and molluscicides. The cut-off of 6 was used to evaluate probable mental disorder. Most of the farmers under investigation were men (53.8%), with a mean age of 55.2 (11.7) years, and were involved mainly in the planting of rice, fruit, and vegetables. About 86.7% reported having used pesticides on their crops at some point in their lives—mostly glyphosate, paraquat, 2,4-D, methomyl, and carbofuran. All functional groups, as well as pesticide classes like organochlorines, organophosphates, and carbamates, were significantly associated with a higher risk of probable mental disorder based on exposure duration, frequency, personal protective equipment usage, and hygienic behavior. In a model with multiple pesticides, there was an association between mental disorder and exposure to endosulfan (AOR = 2.27, 95%CI = 1.26–4.08) and methyl parathion (AOR = 2.26, 95%CI = 1.26–4.06). Having previously reported pesticide poisoning symptoms was related to mental disorder (AOR = 7.97, 95%CI = 5.16–12.31), the findings provided evidence of pesticide exposure posing a risk to farmers’ mental health, particularly long-term and high-intensity exposure.

Hypertension is becoming increasingly prevalent among the elderly. Family caregivers play an important role in caring for elderly people and empowering them to care for themselves. This study’s goal was to see how social support training for family caregivers affected changes in hypertension, total cholesterol, and high-density lipoprotein (HDL), and how such support led to the prevention of hypertension behaviors among the elderly in rural areas. This was a quasi-experimental study with 268 elderly people at risk of hypertension and their caregivers. Sixty seven pairs of elderly people and their caregivers were assigned to the intervention and control groups. Baseline data were collected in November 2020. The intervention group received the Social Support Family Caregiver Training Program (SSFCTP), while the control group received a regular program from the local health authority. The activity lasted 12 weeks, with home visits and telephone check-ups along the way, and data collection took place after the program ended. The final data were collected three months after the end of the intervention. An analysis of repeated measures ANOVA showed the overall effect of the SSFCTP on knowledge, self-efficacy, health care behaviors, and blood pressure among elderly people during three different time periods (p<0.05). Furthermore, the intervention program had a time-dependent effect on knowledge, blood pressure, and total cholesterol levels (p<0.05). In terms of caregiver outcomes, there was an overall difference among the degrees of knowledge, self-efficacy, and behaviors toward health care displayed by elderly hypertensive patients during the three different time periods (p<0.05). The average knowledge and self-efficacy of the participants improved after the intervention. As a result, better self-care behaviors and lower blood pressure and total cholesterol levels were observed among the elderly participants after the intervention. The programs emphasized the importance of caregivers’ roles in providing social support, boosting confidence, and encouraging participation in caring, monitoring, and assisting the elderly in controlling blood pressure and other health issues.

Background: Informal caregivers play an important role in caring for patients with chronic conditions. Little is known about the quality of life among caregivers of patients with chronic illnesses in Thailand. The purpose of this study was to investigate the relationships among knowledge and behaviors toward health care for elderly patients with hypertension, and the quality of life among informal caregivers. Methods: A total of 402 informal caregivers for their elderly co-habitants suffering from hypertension were randomly selected to participate in this cross-sectional study. Data collection was performed in rural areas of Phayao province, located in the northern part of Thailand. Self-administered questionnaires were employed, which covered knowledge and behaviors toward health care for elderly patients with hypertension, and the Thai version of the World Health Organization Quality of Life Brief Version (WHOQOL-BREF) questionnaire. Results: The scores of knowledge and behaviors toward health care for elderly patients with hypertension, and the quality of life were at low and fair levels. In the multivariable linear regression model, the results showed that four variables – age, caregiver’s relationship to the patient, knowledge, and behaviors toward health care for elderly patients with hypertension – were significantly related to quality of life among caregivers (p < 0.05). Conclusion: Knowledge and behaviors toward health care for hypertensive patients influence the quality of life among informal caregivers. The caregivers in rural communities should be encouraged to become educated on the stages of hypertension, preparation for taking care of the elderly with high blood pressure, and effective behavioral care for patients, in order to improve the quality of life of both caregiver and patient. In addition, health care providers should have clear guidelines for development of the health care system to enhance the potential care and quality of life among informal caregivers.

The quality of life (QoL) of elderly diabetic patients may be affected by caregiver factors, but this has received little empirical support. The objective of this cross-sectional study is to determine the influence of family caregivers’ diabetes knowledge and behavior on the QoL among elderly patients with diabetes mellitus (DM). The participants included 354 elderly patients with Type 2 DM and their family caregivers, who were recruited through multistage sampling from five districts in Chiang Mai, Thailand. Face-to-face interviews with DM patients were conducted using the Thai Simplified Diabetes Knowledge Scale (T-SDKS), the Thai version of the Diabetes Self-Management Questionnaire (DSMQ) for self-care behaviors, and the Thai version of the World Health Organization Quality of Life for Older People (WHOQOL-OLD) scale. For caregivers, their diabetes knowledge was measured by T-SDKS and patient-care or supportive behaviors were developed based on DSMQ. The results showed a moderate level of QoL among elderly diabetic patients. According to simple linear regression analysis, the QoL score among elderly DM patients was positively associated with their diabetes knowledge (B = 1.25), self-care behaviors (B = 3.00), caregivers’ knowledge (B = 0.97), and supportive behavior from caregivers (B = 2.92) at a significance level of p < 0.01. In the multivariable model, patients’ self-care behaviors (B = 1.58, p = 0.001), caregivers’ knowledge (B = 0.58, p = 0.001), and patient-care behaviors (B = 1.38, p = 0.004) were significantly associated with QoL among DM patients when controlling for patient factors, including age, body mass index (BMI), education, and living arrangements, which accounted for 27.0% of the variance. This indicates that caregivers’ adequate diabetes knowledge and appropriate supportive behaviors may impact the QoL of elderly diabetic patients. Health care providers should prioritize motivating and empowering family caregivers to pay more attention to the patient for the success goal.

Pesticide-related health concerns are a global public health issue. Few studies in Thailand have explored the hematological and biochemical effects of occupational pesticide exposure. The goal of this study was to investigate the effects of pesticides on the hematology, hepatic, and renal function of Thai vegetable farmers. A cross-sectional study was carried out in Chiang Mai, northern Thailand. A total of 124 apparently healthy vegetable farmers were interviewed about their lifetime exposure to agricultural pesticides. Blood samples were collected via venipuncture to be tested for complete blood count (CBC), liver function, and kidney function. Approximately 46% of the farmers were pesticide users who reported a history of pesticide use for their crops, while 54% were non-pesticide users. In the male farmers, the activities of aspartate aminotransferase (AST), mean corpuscular hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC) were significantly higher in the pesticide users compared to the non-pesticide users, while the estimated glomerular filtration rate (eGFR), hematocrit (HCT), and red blood cells (RBC) were significantly lower (p < 0.05). In the females, the pesticide users had significantly higher levels of alanine aminotransferase (ALT), alkaline phosphatase (ALP), and MCHC than the non-pesticide users (p < 0.05). Pesticide use among Thai vegetable farmers may cause hematological alterations and increase the risk of hepatic and renal dysfunction. Some hematological and biochemical parameters may be used for monitoring to protect them from the adverse health effects of occupational exposure to pesticides.

Purpose: Diabetes patients with low health literacy often have poor health and clinical outcomes. The study aimed to assess the effectiveness of a health literacy intervention on glycemic control and renal function among Thai older adults at risk of type 2 diabetes mellitus (T2DM). Methods: A quasi-experimental study was carried out in rural areas of Phayao Province in northern Thailand. The participants were older adults with T2DM who recorded blood glucose levels ranging from 140 to 180 mg/dL and who were not receiving prescribed medication. The intervention lasted 12 weeks, and data were collected at three points: baseline, post-intervention, and at 3 months’ follow-up. The study outcomes included the measurement of fasting blood sugar (FBS), hemoglobin A1C (HbA1c), and glomerular filtration rate (eGFR) levels after the intervention. A linear mixed model and generalized estimating equations model were used to assess the intervention effect for continuous and binary outcomes, respectively. Results: From baseline to post-intervention, FBS and HbA1c decreased more in the intervention group than in the control group by 8.2 mg/dL (p < 0.001) and 0.1% (p = 0.029), respectively, whereas eGFR increased by 8.0 mL/min/1.73m2 (p < 0.001). The absolute effect of the intervention at follow-up was − 9.8 units for FBS, − 0.4 units for HbA1c, and 14.0 units for eGFR. Abnormal HbA1c level (≥ 6.5%) of the intervention group was reported as 70.3% at baseline, 31.3% at post-intervention, and 9.4% at follow-up. Compared to baseline levels, the T2DM patients who received the intervention were 0.31 times less likely to have abnormal HbA1c levels than the control subjects at follow-up (p = 0.003) who received no intervention. Conclusion: Our findings suggest that this intervention may potentially improve diabetes self-management and prevention behaviors, thereby reducing the diabetes burden in rural communities in northern Thailand.
