ABSTRACT
Background:There are some common diseases found among the students of different areas in Bangladesh which are either communicable or non-communicable. Different infectious diseases occur due to lack of hygiene practice and non-infectious diseases are developed because of many irregular daily habits all over the world. Our aim was to evaluate the habit of practicing hygiene and other daily activities to observe their impacts on the health status among the students from different regions of Chattogram in Bangladesh.Methods:With ethical approval, questionnaire forms of daily habits/activities were filled up by 750 students of different educational institutions. The data were analysed afterwards. Results:Among the population of the study 89% (n=667) students werefound to take regular bath; hand washing was regular among 32% (n=240) students, 54% (n=405) students were irregular in hand washing and the rests wash their hands rarely; on the other hand 41% (n=308) students consume street foods regularly; 38% (n=285) students wear eyeglasses due to weak sight; 23% (n=173) suffer from different skin diseases and 63% (n=473) students usually suffer from different gastro intestinal diseases.Conclusions:Our results are not so frustrating, but also not so much good as majority of the students are fond of unhealthy street foods, don’t wash hands regularly and more than half of the students suffer from GI tract diseases with other health problems. It could be recommended that some daily habits including avoiding street foods, intake of sufficient drinking water and hygiene practices should be improved more.
ABSTRACT
BACKGROUND: Since the night time work was introduced as a ‘harmful factor’ for the worker's special health examination (WSHE) in 2014, the validation of the questionnaire used for screening gastrointestinal (GI) disorder has not been conducted. The purpose of this study is to verify the validity of the questionnaire using the data of specific health screening cluster. METHODS: We used WSHE screening data for 3 years, from 2014 to 2016, in health screening cluster. The subjects who had received upper GI endoscopy in opportunistic screening and WSHE simultaneously regardless of the results of the questionnaire were selected. We tested the validity of the questionnaire using upper GI endoscopy as a gold standard. RESULTS: This study was conducted on 5,057 examinees in 2014, 8,352 examinees in 2015, and 10,587 examinees in 2016. The validity of the questionnaire for each year was as follows: sensitivity 12.3% (95% confidence interval [CI], 11.1–13.4), specificity 88.6% (95% CI, 87.2–90.1), accuracy 41.1% (95% CI, 39.8–42.5) in 2014, sensitivity 5.9% (95% CI, 5.2–6.5), specificity 93.6% (95% CI, 92.7–94.4), accuracy 38.6% (95% CI, 37.6–39.6) in 2015, sensitivity 6.0% (95% CI, 5.4–6.5), a specificity of 9.42% (95% CI, 93.4–95.0), accuracy of 34.2% (95% CI, 33.3–35.1) in 2016. In generally, questionnaire showed sensitivity of 10%, specificity of 90%, and accuracy of 40%. CONCLUSIONS: Despite the purpose of WSHEs aiming to identify target disease early, the sensitivity of the questionnaire for GI disease was too low as 10%. The reasons for this are the problem of the question itself, and the problem of ambiguous target disease. In the future, the questionnaire should be improved to meet the purpose of the WSHE, and further correction of the target disease should be made.
