ABSTRACT
Increased the consumption of polyunsaturated (PUFA)
and omega-3 fatty acid may be one of the strategies to prevent morbidity and
mortality among elderly. This study aimed to identify the plasma fatty acid
profile and intake among older adults who aged successfully (SA)
as compared to the usual agers (UA). This cross-sectional
comparative study was conducted among 48 SA (mean age 66.4+4.7
years old) and 42 UA (mean age 68.4+4.8
years old). The plasma fatty acid profile was determined using gas chromatography.
Fatty acid intake was measured by using the validated Fatty Acid Omega-3 intake
food frequency questionnaire. The percentage of saturated fatty acids (SFA)
in blood plasma of UA (men 62.2+6.4%,
women 62.9+7.0%) were significantly higher (p<0.05) compared to SA (men
53.7+15.8%, women 57.1+9.5%). On the other hand, the
percentage of monounsaturated (MUFA), polyunsaturated (PUFA)
omega-3 and omega-6 fatty acids were the opposites. Fatty acids intake among SA was
higher compared to UA. SFA (SA=5.0+2.5%, UA=4.6+2.9%)
and total omega-3 (SA=0.5+0.4%, UA=0.4+0.3%)
intakes met the recommended nutrient intake (RNI).
However, mean intakes of MUFA (SA=5.3+2.4%, UA=4.7+2.7%)
and linoleic acid (LA) (SA=0.5+0.7%, UA=0.3+0.5%)
were below than the RNI. Percentages of subjects who did
not meet the RNI for omega-3 and MUFA were
44.2% and 97.7% for SA and 47.4% and 95% for UA,
respectively. SA had a higher level of plasma PUFA and MUFA,
but lower in SFA when compared to UA. MUFA and LA were more likely to be inadequate
in the diet of older adults, particularly the UA.

ABSTRAK
Meningkatkan pengambilan asid lemak politaktepu
dan asid lemak omega-3 berkemungkinan merupakan salah satu strategi
untuk mencegah morbiditi dan mortaliti dalam kalangan warga emas.
Kajian ini bertujuan untuk mengenal pasti profil asid lemak plasma
dan pengambilan asid lemak dalam kalangan warga emas penuaan berjaya
(SA)
berbanding penuaan biasa (UA). Kajian perbandingan hirisan lintang
ini dijalankan ke atas 48 orang warga emas SA (purata
umur 66.4+4.7 tahun) dan 46 orang warga emas UA (purata
umur 66.4+4.7) tahun ini. Profil asid lemak ditentukan menggunakan
kromatografi gas. Pengambilan asid lemak pula diukur menggunakan
borang soal selidik Kekerapan Pengambilan Makanan Asid Lemak Omega-3
yang telah disahkan. Peratusan asid lemak tepu (SFA) dalam plasma darah warga emas UA
(lelaki 62.2+6.4%, wanita 62.9+7.0%) adalah lebih tinggi secara
signifikan (p<0.05) berbanding SA
(lelaki 53.7+15.8%, wanita 62.9+7.0%). Manakala peratusan komposisi
asid lemak monotaktepu (MUFA), politaktepu (PUFA),
omega-3 dan omega-6 adalah sebaliknya. Pengambilan asid lemak
adalah lebih tinggi dalam kalangan SA berbanding UA.
Pengambilan SFA (SA=5.0+2.5%,
UA=4.6+2.9%)
dan omega-3 total (SA=0.5+0.4%,
UA=0.4+0.3%)
menepati Saranan Pengambilan Nutrien (RNI). Walau bagaimanapun, purata
pengambilan MUFA (SA=5.3+2.4%,
UA=4.7+2.7%)
dan asid linoleik (LA) (SA=0.5+0.7%,
UA=0.3+0.5%)
pula adalah lebih rendah berbanding RNI. Peratusan subjek yang tidak
memenuhi RNI bagi omega-3 dan MUFA pula
adalah sebanyak 44.2% dan 97.7% bagi SA manakala 47.4% dan 95% bagi
UA.
Kesimpulannya warga emas SA mempunyai tahap PUFA dan
MUFA
plasma yang tinggi, tetapi rendah tahap SFA berbanding
warga emas UA. Pengambilan MUFA dan LA adalah
tidak mencukupi dalam diet warga emas, khususnya UA.
