The epidemiology of physical disability among elderly in Kota Bharu, Kelantan
Globally, the decline in fertility and mortality as well as improvement in life
expectancy ·were said to be responsible for the aging population by the year 2020. In
Malaysia, the elderly population was 1.2 million or 5. 9% of the 20 million total population
in the country in 1995. This number was projected to increase to 11.3% by the year 2020.
Elderly population are prone to get physical disability as well as chronic medical illnesses.
This is a cross-sectional study to determine the prevalence of physical disability and its
associated risk factors among elderly, aged 60 years and above. A total of 270 participants
were taken randomly under 3 health clinics under Kota Bharu oper~tional !areas by using
multistage sampling. Guided- questionnaire were administered and the subjects were asked
to go to clinics or community centre on the appointed date for physical e~amination and
blood taking for fasting blood sugar and total cholesterol. Physical disability was measured
by activities of daily,living ( ADLs) and instrumental's activities of ~aily living ( IADLs).
ADLs is comprise of bathing, dressing, going to toilet, transferring from bed or chair,
continence, and feeding. Whereas IADLs encotnpass the following domestic function :
using the telephone, using transportation, shopping, cooking, house-keeping, taking
medication and budgeting. The IADLs methods offer indicators of" applied " problem that
extend the disability theme of ADLs scales to include some elements of handicap concept.Physical disability was defined as the inability to accomplish one or more ADLs or IADLs.Separate multiple logistic regression was used to determine the risk factors for both
physical disabilities. The prevalence of physical disabilities in ADLs and IADLs were
10.7% ( 95% CI: 7, 14) and 34.8% ( 95% CI: 29, 41) respectively. Significant risk
factors of ADLs were age (OR=2.669, 95%CI: 1.1 07, 6.643), hearing impairment (OR=
. 2.539, 95%CI: 1.034,6.233), diastolic blood pressure (OR= 3.803, 95%CI:1.249, 11.578),
and total cholesterol (OR= 1.535, 95%CI: 1.071, 2.200).Wherea~ for IADL were age
(OR=2.391, 95%CI: 1.185,4.827), income (OR= 0.219, 95%CI:0.078, 0.615),diastolic
blood pressure (OR=2.023, 95°/oCI: 1.038,3.941 ), marital status (OR=2.378,
95%CI:1.227,4.609 ) and obesity (OR=4.679,95%CI:l.544, 14.182). There was a strong
significant association between ADLs and IADLs (OR=9.012, 95%CI:3.400, 23.887). The
prevalence of physical disability for ADLs and IADLs were 10.7% and 34.8% respectively
and it was similar with others studies. These findings also suggested that certain sociodemographic
characteristics ( i.e age, income & marital status ), life-style behavior
( obesity) and medical illnesses (hearing impainnent, total blood cholesterol and high
diastolic blood pressure) were significant risk factors of physical' disability in elderly.
Physical disability in ADLs was a strong predictor for physical disability· in IADL. The
majority of predictors of physical disability that were identified by this study are
potentially subject to modification either by treatment, life-style change or special device.
Public health efforts to reduce prevalence of all these factors in both sexes should continue
A review dengue incidence in Kota Bharu, Kelantan from year 1998-2003
Dengue is the most common and widespread arthropod borne arboviral infection in the world today. It is estimated that there are at least 100 million cases of dengue fever (DF) annually and 500,000 cases of dengue hemorrhagic fever (DHF) which require hospitalization. In Malaysia, it has become one of the major public health problems. The incidence rate of clinically diagnosed DF and DHF reported is showing an upward trend from 8.5 cases/l00,000 populations in 1988 to 88.6 cases/100, 000 populations in 2003. The objective of this analysis was to describe the incidence of dengue fever and dengue hemorrhagic fever in Kota Bharu, Kelantan from year 1998-2003. A total of 4716 dengue cases were notified involving 4476 (94.9%) DF and 240 (5.1%) DHF, which was increasing by years. The highest incidence was in January (701 or 14.9%) while the lowest was in May (188 or 4.0%). Forty percent of cases (n=1890) were in the 15-29 years old group. Majorities were Malays (4062 or 86.1%) and 2602 or 55.2% were male. A total of 4477 cases (95%) were local cases and 4289 or 91% came from urban area. For priority areas, 3772 (80%) were from priority 1. More than half of cases have positive serology result. The mean values for age, temperature, systolic and diastolic blood pressure (BP) were 27.8 + 15.4 years, 37.9 + 0.9 degree Celcius, 115 + 15.2mmHg and 73 + 11.1mmHg respectively. The mean value for time interval befween onset of symptoms and diagnosis, onset of symptoms and notification and time of diagnosis to notification were 5.1 + 2.3, 5.9 + 2.5 and 0.8 + 1.1 days respectively. All symptoms occurred in more than 96% of cases and fever was the commonest (99.7%). The incidence of dengue in Kota Bharu is comparable to that of in Malaysia. The increase in the number of cases needs to be addressed promptly with effective surveillance, prevention and control programs
