Abstract

Background: Lung cancer remains a major global public health problem and is one of the leading causes of cancer-related mortality, particularly among the elderly who are more vulnerable due to age-related physiological decline and prolonged exposure to risk factors such as smoking and environmental pollutants. Despite ongoing preventive efforts, limited knowledge and awareness regarding lung cancer prevention among older adults continue to hinder effective control strategies. This study aimed to determine the effect of booklet-based health education on the level of knowledge regarding lung cancer prevention among the elderly. Methods: This study employed a quantitative pre-experimental design using a one-group pretest–posttest approach. The study was conducted in the working area of UPTD Puskesmas I East Denpasar, Bali, Indonesia. The sample consisted of 103 elderly individuals selected through purposive sampling. Primary data were collected using a structured questionnaire measuring knowledge levels, while secondary data included respondent characteristics. Data were analyzed using descriptive statistics and the Wilcoxon signed-rank test. Results: The results showed that prior to the intervention, the majority of respondents had poor knowledge (59.2%), which decreased to 9.7% after the intervention. Conversely, the proportion of respondents with good knowledge increased from 11.7% to 47.6%. The mean knowledge score also increased from 49.26 to 74.39, with a statistically significant difference (p = 0.001). Conclusions: In conclusion, booklet-based health education was associated with a significant improvement in knowledge regarding lung cancer prevention among the elderly. This intervention can be considered a practical and effective strategy for enhancing health literacy in community settings.

Abstract

Background: Nutritional habits, hygiene practices, and lifestyle attitudes are recognized as important decisive factors of health and academic performance among university students. However, available literature from developing countries, particularly Bangladesh, remains limited. This study aimed to evaluate the relationship between nutritional awareness, hygiene practices, lifestyle factors, and their effects on health outcomes and academic concentration among tertiary-level students in Chattogram City, Bangladesh. Methods: A cross-sectional study was conducted among 93 tertiary-level students selected through convenience sampling. Data were collected using a structured questionnaire covering demographic characteristics, dietary habits, hygiene practices, lifestyle factors, and academic performance indicators. Composite scores for hygiene and nutrition were generated by converting ordinal variables into numerical scales. Descriptive statistics (mean ± standard deviation) were calculated, followed by correlation analysis and multiple linear regression to assess associations between independent variables and outcomes like academic concentration and grade point average (GPA). Results: The mean age of participants was 20.51 ± 1.74 years. The average sleep duration, screen time, GPA, and academic concentration scores were 6.66 ± 0.91 hours, 5.39 ± 2.17 hours, 3.41 ± 0.42, and 6.58 ± 1.60, respectively. Correlation analysis showed weak relationships among variables, with sleep duration showing a weak positive association with academic concentration (r = 0.14) and GPA (r = 0.08), while screen time revealed a weak negative correlation with GPA (r = -0.07). Regression analysis pointed out that none of the examined factors were statistically significant (p > 0.05). Conclusions:The findings suggest that individual lifestyle, nutritional, and hygiene factors have limited independent influence on academic performance and concentration among students. Academic success cannot be explained by some specific lifestyle variables in isolation, but rather through complex interactions among multiple determinants.  Future studies with larger sample sizes and longitudinal designs are recommended to better understand these relationships.
