    Relationship between knowledge, risk perceptions and socio-demographic factors and tuberculosis diagnosis in Ntcheu District in Malawi.
    (2012) Chizimba, Robert Mnthenga
    Aim of the study: The main aim of this study was to determine socio-demographic characteristics associated with being diagnosed with TB by a health care worker among adult males and females aged between18-49 years in Ntcheu district, Malawi. Method: This was a descriptive and analytical cross-sectional study. A total of 121 adult women and men were sampled using a three-stage simple sampling technique. The 2008 Population and Housing Census enumeration areas (EAs) were used as a sampling frame. The first stage involved simple sampling of two Traditional Authorities (TAs) out of nine (9). Stage two involved selection of ten villages in each sampled TA. The third level of sampling was a selection of six households from each selected village where the first dwelling was also sampled. A structured questionnaire was developed in English and translated into Chichewa. The questionnaire was administered by a trained interviewer at each respondent’s household. Three research assistants were employed to collect data. Results The awareness of TB was universal with every participant reporting that they had heard about TB. Of the 121 participants, more than half were male (53.7%; n=65).The median age of the respondents was 28 years (range 18-49 years) and approximately a third of the respondents (34.4%; n=31) had 1-2 children. The study found that higher education (p=0.01), higher ownership of household assets (p=0.01), higher average monthly household income (p=0.02) and higher socio-economic status of the respondents (p=0.01) were significantly associated with higher knowledge of causes of TB. It was found that education was also associated with knowledge of the transmission of TB (P=0.01). The lower the level of education the lower the knowledge level on the correct modes of TB transmission. There was also an association between knowledge of symptoms of TB and occupation (p=0.05). It was found that farmers were less likely to know symptoms of the disease compared to other forms of occupation namely: business persons, those participants who were employed and those not employed. The study found that women had significantly lower risk perceptions of the disease (p=0.01). No association was found between socio-economic and cultural factors of the respondent and self-reported TB diagnosis. Conclusion The findings of this study show that a comprehensive health promotion programme is required in order to address significant gaps on knowledge of causes of TB, transmission, symptoms and risk perceptions and other related socio-economic and cultural factors in Ntcheu district.
