program to reduce sugar consumption, self-efficacy theory, social support, overweight women


           This quasi-experimental research was aimed to study the effects of a program to reduce sugar consumption by applying the self-efficacy theory with social support. The samples were 75 overweight women who had body mass index (BMI) ³ 23 kg/m2 but not higher than 30 kg/m2 and aged between 30 to 59 years old. Thirty-seven of them were separated into the experimental group and thirty-eight women were put into the comparison group. The experiment took 11 weeks. The data collection was done before and after the experimentation on the 1st and 12th weeks by using the questionnaire. The questionnaire was tested by content validity and found to be reliable using Cronbach's alpha coefficient. The data analysis was done by using descriptive statistics such as frequency, percentage, mean, and standard deviation. The difference was tested by computing the chi-square test, paired t-test, and independent t-test.

            The results showed that after the experimentation, the experimental group had a significantly higher level of knowledge about sugar consumption, perceived self-efficacy to reduce sugar consumption, and outcome expectation of reducing sugar consumption than before the experimentation. The experimental group also had significantly better/more appropriate knowledge in reducing sugar consumption behaviors than before the experimentation and the comparison group. Besides, significantly different body weight was found between the two groups. The average decreased body weight of the experimental group was found to be .40 kilograms compared to the increased body weight of .90 kilograms of the comparison group. Thus, this sugar consumption reduction program can be applied to the people in the areas that are in the responsibility of the Public Health Service Center of Bangkok Metropolis or health-promoting hospitals with similar contexts.
