A Family’s Knowledge and Attitudes Toward the Prevention of Pulmonary Tuberculosis in Tasikmalaya City, Indonesia, in 2023: A Cross-sectional Study

Background: Disease prevention is an important component of health care. Knowledge and attitudes are supportive factors in implementing healthy behaviour for tuberculosis (TB) prevention. This study aims to identify the relationship between the level of knowledge and family attitudes in preventing pulmonary TB. Methods: This cross-sectional study employed a quantitative analytical design. The study sample comprised a family of TB patients obtained with the total sampling technique (82 respondents). The study instrument was valid and reliable, with favourable Cronbach α values for knowledge (0.961) and attitudes (0.976). Data analysis in the study used univariate (category with cut-off point for all variables), bivariate (Chi-square) and multivariate analysis (logistic regression). The study was conducted at the Tamansari Public Health Center in Tasikmalaya City, Indonesia. Results: A total of 82 samples participated in this study. The results showed that the majority of respondents have good knowledge (63.4%), positive attitudes (62.2%) and good prevention strategies (67.1%). Based on the results of statistical tests using the chi-square, there was a significant association between family knowledge of TB prevention (P=0.012) and family attitudes toward TB prevention (P=0.020). The most dominant factor influencing TB prevention was knowledge (odds ratio (OR)=3.333) compared with attitudes. Conclusion: Knowledge becomes a dominant factor compared to attitudes among TB patients. A family with good knowledge can support better information relating to the disease of TB patients during treatment and may increase self-care adherence.
