20 June 2018 ABSTRACT A structured weight
management programme at a workplace
may help in reducing the prevalence of overweight and obesity.
Therefore, this intervention study was to determine the effectiveness
of weight loss programmes including
face-to-face, online and control group at workplace among employees
who are overweight and obese. A total of 108 overweight and obese
adults were recruited and randomly divided into three groups (face-to-face
group (FT),
n=38; online group (OG), n=31; control group
(CG),
n=39). In the FT group, the participants took part
in health talks, interactive activities and counselling; the OG group
was given access to an online weight management program and the
CG group
was provided with educational booklets on weight loss. All information
given was related to nutrition, physical activity and motivation
to reduce weight. Body weight, body mass index (BMI), waist circumference (WC),
body fat percentage, dietary intake, fasting lipid profile and
glucose levels were assessed at baseline and 4 months. The FT group
showed greater reduction in body weight (-5.80 kg) compared to
OG (-1.12
kg) and CG (-1.82 kg). Significant interaction effects were found
for BMI, WC, fasting serum triglycerides, HDL-cholesterol
and total cholesterol/HDL-cholesterol ratio (all p<0.05),
with the FT group showing the biggest improvements, compared to the
other groups. The face-to-face weight management program offered
in the workplace showed to be the most effective at improving
anthropometric profile, fasting serum triglycerides, HDL-C, total cholesterol/HDL-C
ratio, and dietary intake among overweight and obese employees. Keywords: Intervention;

pengurusan berat
badan berstruktur di tempat kerja boleh
membantu dalam
mengurangkan berat badan berlebihan dan obesiti. Oleh itu, kajian intervensi adalah untuk menentukan keberkesanan program penurunan berat badan iaitu
bersemuka, atas
talian dan kumpulan
kawalan di tempat
kerja dalam kalangan
kakitangan yang berlebihan
berat badan dan
obes. Seramai
108 kakitangan yang berlebihan berat badan dan
obes telah
direkrut dan dibahagikan
secara rawak
kepada tiga kumpulan
(kumpulan bersemuka
(FT),
n=38; kumpulan atas
talian (OG), n=31; kumpulan kawalan (CG),
n=39). Subjek
kumpulan bersemuka diberikan ceramah kesihatan, aktiviti interaktif dan kaunseling; kumpulan OG
diberi akses untuk
satu program pengurusan
berat badan atas
talian dan
kumpulan CG disediakan
buku kecil
yang mengandungi maklumat mengenai penurunan berat badan. Semua maklumat yang diberikan adalah berkaitan dengan pemakanan, aktiviti fizikal dan motivasi untuk
menurunkan berat
badan. Penilaian berat badan, indeks
jisim tubuh
(BMI),
ukur lilitan
pinggang (WC), peratus
lemak badan,
pengambilan makanan, profil lipid dan aras glukosa darah
berpuasa dilakukan
pada peringkat dasar dan 4 bulan.
Kumpulan FT menunjukkan penurunan berat badan tertinggi (-5.80 kg) berbanding OG (-1.12 kg) dan CG (-1.82 kg). Selain
daripada berat
badan, didapati terdapat kesan interaksi yang signifikan bagi BMI, WC,
trigliserida, kolesterol-HDL,
dan nisbah
kolesterol/kolesterol-HDL
(p<0.05), dengan
kumpulan FT
menunjukkan penambahbaikan lebih tinggi berbanding
kumpulan yang lain. Program
pengurusan berat badan bersemuka yang ditawarkan di tempat kerja adalah yang paling berkesan dalam meningkatkan profil antropometrik, trigliserida, HDL-C,
nisbah kolesterol/HDL-C
dan pengambilan
makanan dalam kalangan
kakitangan berlebihan
berat badan dan
obes. Kata kunci: Intervensi;
