Abstract

|
The purpose of this paper is to determine the percentage of body fat by measurement of skin-jold thickness of the triceps and the subscapular area and to investigate the relationship between the daily energy intake and expenditure among obese
women
and
nonobese women based on the jpercentage of body fat and age.
@ES The survey included 422 females in Cheju.
@EN 1) The age distribution of the 422 females surveyed was : 26.8% were in their 20's, 20.6% in their 30's, 21.3% in their 40's, 19.0% n their 50's, and 12.3% were above 60 years of age. The 422 females consisted of 78% housewives, 12.8% college
student and 9.2% single working women.
2) The average height and weight of the surveyed women were respectively 159.0±4.2cm and 56.0±7.2kg, the percentage of body fat of the surveyed women 24.8±9.8%, and the BMI of those surveyed was 22.7±2.7. If higher than 30% body fat was
defined as
being obese, 15.6% of the surveyed women were assessed to be obese.
3) total daily food consumption and energy intake of the group of women aged 60 and older was significantly small. Food consumption and nutrient intake of obese women was greater than that of the nonobese group. but not significant. Carbohydrate
intake
of the obese group in their 40's was significantly higher than the nonobese group. total food consumption, energy and carbohydrate intake of the obese group in their 50's was significantly higher than the nonobese group. Vegetable intake of the
obese
group in their 60's and older was significantly higher than the nonobese group.
4) The total tme of physiological activity of women aged 60 and older was significantly higher than for the other age groups and the total work time was significantly lower, The total work time of women in their 20's was not lower than the other
groups. Consideering the low energy expenditure of physical activity for women in their 20's, they appeared to have light activity,. However, there was not a significant difference in the physical activity time among middle aged women group (from
30 to
50). The entire energy expenditure of the obese group was greater than the nonobese group. However, the energy expenditure per body weight in the obese group was significantly less than that of the nonbese group in terms of the basal metabolic
rate
in
consideration of the fat free mass.
5) There was a positive correaltion between the percentage of body fat and the factors of age, sleeping time, total time of physiological activity, housework time, time spent watching TV, energy expenditure, energy intake, carbohydrate and
cereal
consumption. On the other hand, the percentage of body fat was negatively correlated with energy expenditure per body weight based on the basal metabolic rate in consideration of the fat free mass.
