According to Krejcie and Morgan’s54 method, the number of
subjects (n) in the study was calculated. Allowing for 10% of dropouts, the
calculated sample size required for this study was 62 for the case group and 62
for the control group (N = 124). The expected effect size is 0.50 since this
would provide the maximum sample size. A total of 124 mothers consisting of 62
mothers of malnourished children (case) and 62 mothers of well-nourished
children (control) were chosen using a simple random sampling method from the
list of children provided, who registered at the government health clinics in
Kuala Langat district, Selangor, Malaysia. The child’s age, gender and
residential area in the case group were matched with the child in the control
group. Anthropometric measurements such as current body weight, height,
mid-upper arm circumference (MUAC) and head circumference (HC) of children were
measured. The anthropometric status of the children was categorized based on the
World Health Organization (WHO)55 growth chart and
classification.
