Abstract
Background: Impaired fasting glucose level has been associated with increased
incidence of Type 2 Diabetes mellitus, and diabetes is becoming a major public
health problem in developing countries. The objective of the study was to deter-
mine the prevalence and correlates for impaired fasting glucose level/diabetes in
Kaoma and Kasama rural districts of Zambia.
Methods and Findings: A cross sectional study using modifed World Health
Organization (WHO) global non communicable diseases (NCD) surveillance initiative
NCD STEPwise approach was used in the study. Proportions were compared using
the Yates’ corrected Chi-square test, and a result yielding a p value of less than 5%
was considered statistically signifcant. Bivariate and multivariate logistic regression
analyses were conducted. Factors that were statistically signifcantly associated with
the outcome in bivariate analyses were considered in a multivariate logistic regres-
sion analysis using a backward variable selection method. Odds ratios (OR) and
their 95% confdence intervals (CI) have been reported. Totals of 895 participants
from Kaoma and 1198 from Kasama took part in the surveys. Overall, 4.1% of
the participants in Kaoma and 1.8% of the participants in Kasama (p=0.004) had
impaired fasting glucose level/diabetes, with no signifcant differences between
sex in both districts. Respondents who were aged less than 45 years were less
likely to have impaired glucose level/diabetes compared to those who were aged
45 years or older (OR=0.56, 95% CI [0.39, 0.81] in Kaoma and OR=0.55, 95% CI
[0.33, 0.89] in Kasama).
Conclusions: Prevalence of impaired fasting glucose level/diabetes may have been
underestimated because impaired glucose test was not conducted. The prevalence
of impaired fasting glucose level/diabetes varied between the two rural districts stu-
died. Impaired fasting glucose level/diabetes was associated with age. Interventions
to control diabetes should be district specifc and targeted at younger age groups
in order to curtail the prevalence of diabetes in older age groups.
