The Effect of Soy Milk and Boiled Peas to Waist Circumference in Postmenopausal Women
Keywords:Soy milk, boiled peas, waist circumference, postmenopause women, estrogen
Background: A woman’s life period after 12 months from the last menstruation is called the postmenopause
period. Estrogen affects the accumulation of gluteo-femoral fat. Decreased estrogen levels cause abnormal
redistribution of fat and increase central fat. Postmenopausal women are at greater risk of central fat
accumulation. This can be detected by measurement of waist circumference. Soybeans (Glycine max) has
antioxidant and hypolipidemic effects also reduce waist circumference and waist-hip circumference ratio.
Peas (Pisum sativum) contain soluble fiber which can reduce blood lipid levels. The aim of this study was
to analyze the effect of soy milk (Glicyne max) and boiled peas (Pisum sativum) on waist circumference
in postmenopausal women. Method: This study is an experimental research with pre-post test and control
group design. The population of study is were postmenopausal women patients in Magelang, Central of
Java. The sample of study amounted to 39 postmenopausal women divided into three subject groups, one
control group, the second group given treatment 240 ml soymilk per day 4 weeks, and the third group was
given the intervention of 100 g boiled peas per days 4 weeks. Data is presented as mean (mean) and standard
deviation (SD). The mean values of the three study groups were statistically tested with the ANOVA test.
Results: The findings of the study is consumption 240 ml of soymilk per days 4 weeks in postmenopausal
women decrease waist circumference but not statistically significant. Consumption 100 g of boiled peas per
days 4 weeks in postmenopausal women decrease waist circumference statistically significant (-0,19 ± 0,38
cm, p= 0,096). Conclusion: Consumption 100 g of boiled peas per days 4 weeks in postmenopausal women
decrease waist circumference statistically significant (-0,19 ± 0,38 cm, p= 0,096).
