Parasitic infections in Kuwait: A study based on Primary Care Centers
and Methods: A
cross- sectional sampling survey was conducted in five health regions of
Kuwait, from December 2001 to August 2002, for all age groups.
Four primary health care clinics were selected randomly
from each health
region. One thousand questionnaires were distributed, and 912 completed
questionnaires were received from the patients, who presented with
gastroenteritis symptoms. The questionnaire included personal
information with socio-demographic
results of stool examination.
total of 912 participants in the study, comprised of 607 (66.6%) males and
305 (33.4%) females. 354 (38.8%) were Kuwaitis. Based on stool examination,
255 (28%) subjects were found to be positive for different types of
parasitic infections. There was no significant difference in the
prevalence of parasitic infection among gender and nationality, but was
significantly higher among children (p<0.001). Infection was
significantly higher (p<0.001) among people with education up to
intermediate or none, as well as, those with low or middle class income
(p<016) and also among the unmarried patients. The highest prevalence
of parasitic infection was found in Al-Jahra and Al-Ahmadi health
regions, about 48%, and the least in
capital health region 15.8%.The most
common type of parasite found was Enterobius vermicularis, 27.1% and was
significantly higher (74.6%) among children (p<0.001). The E.
histolytica and E.Coli
was significantly higher among adults.
study showed that the parasitic infections were more prevalent
among population with low
socio-economic conditions. Hence, efforts are
needed to increase prevention programmes and also to improve such conditions
in the regions with high prevalence.
prevalence, Enterobius vermicularis, Entamoeba histolytica,
objective of this study was to determine the prevalence of different
types of parasitic infections among patients attending primary health
care clinics in Kuwait,
and its prevalence in relation to various socio-demographic factors and variations
in different health regions.
SUBJECTS AND METHODS
cross-sectional sampling survey was conducted in five health regions, during
an eight- month period, from December 2001 to August
2002. Four primary
health care centers were selected randomly from each health region.
One thousand questionnaires were distributed, of which 912 were completed from patients who attended the clinic for gastrointestinal symptoms including abdominal pain, diarrhea, perianal itching and anemia .Since the majority of individuals from the developing countries generally may not present with any of gastrointestinal symptoms, thus the carriers have been excluded .The questionnaire included information on age, gender, nationality, marital status, level of education and family income, results of stool examination and type of parasitic infection. All stool specimens of 912 patients were submitted for routine Stool examination. All specimens were examined by the direct fecal smear with saline or Lugolís iodine, formalin-ether concentration method (4) replacing ether with ethyl acetate and trichrome staining method which is the Wheatley modification of Gomoris's trichrome stain (5).
The patientís age groups were divided into children (from 0 to 12 years) and adults (more than 12 years). The data was transferred to the Statistical Package for Social Sciences (SPSS) software (PC version 11.0) for statistical analysis. Chi-square or Fisherís exact test was used to establish any associations between the variables and infection or to test the proportions. A probability level of p ≤0.05 was considered significant.
