Brief Summary

The study was designed as a descriptive cross-sectional survey conducted between February and October 2022. Senior management officials were targeted because of their role in workplace policy and oversight. The sample was drawn from companies registered under the Zambia Chamber of Commerce and Industry (ZACCI), focusing on those with known silica dust exposure. Each company was asked to provide one or two senior officials to participate. A total of 118 individuals completed the survey. Data collection was carried out using a self-administered electronic questionnaire developed in line with WHO recommendations for TB KAP surveys. The questionnaire contained 28 mandatory closed-ended questions: 7 on knowledge, 8 on attitudes, and 13 on practices (with 5 practice questions excluded from scoring as they were programmatic). Responses were validated by three medical doctors, and scoring was based on correct answers. Knowledge, attitude, and practice scores were categorized into "poor" or "good" using mean or median cutoffs depending on distribution. Logistic regression was applied to explore associations between participant characteristics and KAP outcomes.

Study Population

The sample population was drawn from the Zambia Chamber of Commerce and Industry (ZACCI), an umbrella organization representing businesses across all sectors. ZACCI advocates for workplace legislation and a conducive business environment. Companies known to produce silica dust were identified under categories including mining, construction, cement manufacturing, brick and tile manufacturing, and glass and ceramic manufacturing. The sampling frame included 1 mining company, 73 construction companies, 1 cement company, 9 brick/tile companies, and 10 glass/ceramic companies. Each company was asked to nominate at least one senior official to complete the questionnaire, with a maximum of two responses per company. This ensured representation across industries while maintaining focus on individuals with policy-making authority.
