Exposure to Lead of Boatyard Workers in Southern Thailand: Chamnong THANAPOP, et al. Epidemiology Unit, Faculty of Medicine, Prince of Songkla University, Thailand-Lead oxide is used extensively in the construction and repair of wooden boats in Thailand, but the behaviors of boatyard workers that could place them at risk of contamination have not previously been documented. Baseline data on practices and behaviors of boatyard workers and on the level of worker and workplace contamination with lead were therefore collected. Fifty workers in two boatyards participated in this study. Lead exposure of workers was assessed by determining airborne and blood lead levels. A questionnaire was administered to collect information on work history, suspected exogenous lead sources, personal behavior and knowledge about lead. Evidence obtained by the study indicated that safety behavior and personal hygiene were poor-workers used no mask, gloves or hood, wore open sandals, smoked, drank, chewed and ate during work and did not wash their hands before drinking or eating. Some workers had lunch in the working area. The mean personal airborne lead of caulkers (36.4 µg/m 3 ) was higher than that of carpenters (8.3 µg/m 3 ). Forty-eight percent of all workers and 67% of caulkers had a blood lead level (BLL) exceeding 40 µg/dl. Multiple linear regression indicated that blood lead levels of workers were significantly related to job and education level, with significant differences between boatyards. In addition, the potential for "takehome" contamination was high; none of the workers took a shower or changed their clothes prior to going home. These results indicate a problem of lead exposure of sufficient magnitude to be a public health concern. (J Occup Health 2007; 49: 345-352)

Surface-wipe lead loading was measured at various locations in the homes of 31 boat-caulkers and 31 location-matched controls to identify factors associated with household lead contamination. Data were obtained by observation checklist and questionnaire. Lead loading was significantly higher in caulkers’ than in control households. Median lead loadings (in µg/ft2) of various locations in caulkers’ homes were windowsill, 43.9; exterior entrance, 9.5; interior entrance, 21.1; living room floor, 9.8; and bedroom floors 15.6. Corresponding levels in control homes were all less than 0.2 µg/ft2. Regression modeling indicated that lead loading was higher in caulkers’ homes that were closer to a boatyard, in which the caulker had a longer duration of boatyard work, and in which there were no children aged under 6 years resident. Exterior and interior entrance and living room floors had lower lead loading than windowsills. However, bedroom floors had significantly higher lead loading, similar to windowsills.

Background Thai society is becoming an ageing society. Independent older persons need to be able to continue to work after retirement. The Work Ability Index (WAI) is an assessment tool for improving the health and work environment of the older workers. The objective of this study is to explore work ability and its related factors among older workers in formal and informal sectors in southern Thailand. Methods This cross-sectional study with multistage sampling focused on 324 Thai older workers, aged between 45 and 70 years, working in Nakhon Si Thammarat province. Data on sociodemographic status, health history, and work-related factor questionnaires were collected, including anthropometric measures and the WAI instrument between March and September 2019. Descriptive and logistic regression analyses were used to examine associations. Results The participants were predominantly general labourers (23.8%) and female (70.7%). Nearly half of them had noncommunicable chronic diseases (NCDs) (48.2%) and were obese (more than 60%). Approximately 60% (59.9%) engaged in safe working practices. The participants sometimes received occupational health services (51.9%) and frequently accessed health promotion services (78.1%). There was a significant difference in the total average WAI score of the formal and informal workers: 40.6 (S.D. = 4.6) and 37.5 (S.D. = 5.0), respectively. The multivariate analysis showed that workers aged 55 years and older (adj. OR = 1.45; 95% CI [1.21, 1.74]), those with NCDs (adj. OR = 2.85; 95% CI [1.69, 4.80]), and those who were exposed to unsafe working practices (adj. OR = 2.11; 95% CI [1.26, 3.55]) had a higher risk of a poor to moderate WAI. Conclusions Most of the older workers had good to excellent work ability. Older age and the presence of NCDs were negatively associated with good to excellent work ability. Safe working practices improved older workers’ work ability. Integrated occupational health protections and health promotion programmes for older informal workers should be provided by community health services to improve work ability.

Tuberculosis (TB) prevention in prisons remains a problem that requires advocacy and partnership action. A correctional officer (CO) is responsible for enforcing the rules and maintaining routines at a prison and has the authority to support TB prevention under the limitations of health manpower in prisons. The objective of this cross-sectional study was to determine the health literacy (HL) and practices of TB prevention and their association among Thailand’s COs. A total of 208 COs participated using a random sampling method. A self-administered questionnaire on HL and TB prevention practices was used for data collection. Descriptive statistics, Pearson’s chi-square test, and binary logistic regression were used for the association analysis. The majority of the participants were male (71.2%), married (60.1%), had a bachelor’s degree (60.6%), and had never been trained in TB prevention (90.9%). In total, 63.0% had adequate HL, whereas 78.4% had good practices, and this corresponded with personal prevention (75.5%) and work prevention (74.6%). Significant associations were identified for education, and communication, decision-making, and self-management skills (p < 0.05). The probability (adjusted odds ratio [95% CI]) of good practices was higher among participants with adequate communication skills (7.92 [2.15–29.24]), adequate decision-making skills (6.00 [1.86–19.36]), bachelors’ degree or higher-level education (3.25 [1.12–9.39]), and adequate self-management skills (2.95 [1.08–8.11]). The study findings show that most of the COs have adequate HL which is associated with good practices in TB prevention. Prisons should support HL development among COs for partnership and sustainable TB prevention under the constraint of health personnel.

Purpose Thailands’ informal workers are faced with job insecurity and poor working conditions. Good health status can promote lifelong working and increase quality of life. This study analyzed factors associated with the health status of the community informal workers. Methods A cross-sectional study was conducted with 390 informal workers aged 15 to 59 years in Thasala district, Nakhon Si Thammarat, southern Thailand. A multi-stage sampling method using proportional to size selection was employed in various types of informal workers. The interviews on self-reported health status, health behaviors, occupational hazards, healthcare utilization, occupational health and safety (OHS) access are reported as descriptive. The multivariate association was explored using the simple logistic regression. Findings The results revealed that 80.77% of the participants had good health, 57.44% had healthy behavior, 76.41% had safe work practices, 22.05% had moderate to high exposed of occupational hazards, and 56.41% had the low OHS access. Safe work practices, moderate to high OHS access, low exposed to occupational hazards, and low income were more likely to produce good health status, which yielded the adj. OR 2.57, 1.86, 0.39, and 0.48, respectively. Conclusions The community informal workers health status was associated by income, work practices, occupational hazards, and OHS access. To strengthening the informal workers’ health, the OHS program should be managed intensively by the primary care services, especially the OHS risk management.
