Trend analysis of tuberculosis incidence in Nepal during 1996-2003
Abstract:
A descriptive study was conducted to describe the ongoing pattern and trend of TB incidence in Nepal during 1996-2003, regarding person, place, and time. The study was conducted using secondary sources of information obtained from regular TB surveillance data collected during 1996-2003. Compared with the expected incidence rate during this period, the epidemiological situation of tuberculosis in Nepal was a major public health problem. The overall trend of tuberculosis incidence rate in Nepal was decreasing per year by an amount 0.81/100,000. The sex ratio for the incidence rate of new pulmonary positive TB cases was equal to 2:1. The trend of incidence rate of pulmonary positive TB showed that males had a more steadily increasing rate than females. Sex ratio of age specific incidence rate for the pulmonary positive TB was almost similar to the age group 0-14, with the highest ratio for the age group 55-64 years old. Considering types of TB, the reporting ratio of males and females for extra pulmonary and standard chemotherapy cases were the same, while the highest was found among re-treatment cases. The reported incidence rate of pulmonary and extra pulmonary tuberculosis cases was almost 6.2:1. Different incidence rate was reported in different seasons during this period. The standardized incident rate showed that the highest incidence rate was reported from the regions of CDR followed by MWDR, WDR, EDR and FWDR with ratios equal to 1.6:1.2:1.3:1.4:1 respectively. A high incidence rate was reported from flat (Terai) ecological zones followed by hilly and mountainous ecological zones with ratio equal
to 3.1:2.07:1. The resources should be allocated according to the burden of TB, considering person, place, and time. TB health education priority should be given to females and productive age groups of both sex. The community mobilization of people and the TB patients living in flat and hilly ecological zones should be of higher priority than the people living in a mountainous ecological zone. Awareness for the protective behavior for TB has to be proposed during the summer season followed by rainy and winter seasons, focusing on CDR followed by MWDR, FWDR, WDR and EDR.
