| Summary: | 碩士 === 台北醫學院 === 保健營養學系 === 86 === Shift work affects workers'' health due to the change in eating, sleeping
and living patterns. Recent studies indicated that shift work was associated w
ithincreased risk of cardiovascular disease(CVD) of male workers, but less stu
diesinvestigated on female worker. The present study was aimed at comparing da
y,evening and night fixed shiftt female workers with respect to dietary patter
ns and physiological status. The investigation was conducted in Jan. 1996
in two electronic plants in Taiwan.The 145 shift workers worked a fixed three-
shift schedule(day shift,7:00-15:00; evening shift, 15:00-23:00; night shift,
23:00-7:00). A ques-tionnaire was disrtibuted to understand eating habit, nutr
itional knowledge,sleep quality, psychological health and work stress. The fas
ting venous blood was also collected to detect the concentration of plasma tot
al cholesterol(TC), hight-density lipoprotein (HDL-C) cholesterol, low-density
li-poprotein (LDL-C) cholesterol, triglyceride, vitamin A,C,E and activity of
anti-oxidant enzymes (Glutathione peroxidase, Superoxide dismutase). From
questionnaire showed that evening shift workers had the worst eating habit a
bout fat and obtained the lowest scores of nutritional knowledge than other tw
o groups. The estimated cholesterol, curde fiber, vitamin A and C intakeamong
the three groups was no difference by food frequency method. Among all subject
s, we found the strong correlation between work stress, sleep quality and psyc
hological health. The study also indicated that night shift worker had signifi
-cantly higher blood pressure than day and evening shift workers. TC/HDL-C and
LDL-C/HDL-C ratios of the evening and night shift workers were significantlyh
igher than those of day workers, even if TC and LDL-C level in normal range.Th
e concentration of plasma vitamin A,C,E and activity of antioxidant enzymes we
re no difference among the three groups. In conclution, the disturbance of die
tary pattern, sleep quality and abnormal blood pressure, plasma TC/HDL-C and L
DL-C/HDL-C ratios were found in shiftworkers, especially evening and night fix
ed shift workers, howere, no effect on psychological health and anti-oxidative
status were found.
