Dietary fibre (DF) and fluid intakes
have been reported elsewhere to reduce the risk
of constipation. The association of these dietary
components on Agachand’s Constipation Score (CS)
was investigated in the present study.
Methods: A total of 202 Malaysian participants
comprising 50 adolescents (aged 12.4 ± 5.3 yrs),
50 adults (aged 46.3 ± 11.3 yrs), 52 women of childbearing
age (aged 29.1 ± 9.3 yrs) and 50 elderly persons
(aged 70.0 ± 7.4 yrs) were recruited by convenience
sampling from five venues - two communities in Cheras,
one community in Klang, the IMU campus, Bukit Jalil
and a private secondary school in Klang. All participants
were interviewed with a previously-evaluated food
frequency questionnaire (FFQ) and an Agachand’s
Constipation Score (CS) Questionnaire.Results: Mean daily DF intakes were low across all
age groups with means ranging from 10.0 – 15.6g.
The percentage of subjects with daily DF intakes below
the “deficient” cut-off of 20g was alarmingly high;
80% in adolescents, 45% in adults, 85% in women of
child-bearing age and 70% in the elderly. About onefifth
or 20% of subjects in all age groups had CS values
≥15 which indicated a problem of constipation.
Mean daily total fluid consumption (TFC) ranged
from 2128 – 5490 ml in the four categories of subjects.
Overall, both daily DF intakes and TFC were negatively
associated with CS values. This inverse association was
significant for DF vs CS scores in adolescents (r = -0.500,
p = 0.001), adults (r = -0.351, p = 0.013), the elderly
(r = -0.392, p = 0.005) and all subjects combined
(r = -0.366, p=0.001). For TFC vs CS scores, the
inverse association was only significant for the elderly
(r = -0.312, p = 0.027) and all subjects combined
(r = -0.245, p = 0.001).
Conclusion: The results of this study support the role
of dietary fibre intake and TFC in reducing the risk of
constipation, as well as reinforcing previous data for low
DF intakes among the Malaysian population.
