The effect of knowledge enhancement and Non Khaen life design on body mass index among working-age groups aged 22–59 years in Sang Tho Noi Subdistrict, Hua Taphan District, Amnat Charoen Province

Abstract

Objective: The purpose of this study was to compare the effects of knowledge-enhancing programs and designing the Non Khaen life design within group and between group (experimental group and comparison group).

Materials and Methods: This research was a two-group Quasi-Experimental study. The sample size was calculated by the formula for comparing two populations independent of each other: 37 people each. Then a simple random sampling was performed. Data were collected using a questionnaire with a reliability of 0.902. The data were analyzed by descriptive and inferential statistics (Independent-Sample T-Test).

Results: The results showed that the two groups of samples were similar in that they were male, with an average age of 49 years and a monthly income of between 5,000 and 9,999 baht, without underlying disease. No current illness and exercise for a long time. After the experiment found that the mean body mass index before and after joining the program was significantly different in the experimental group, p=0.016. There was no statistically significant difference. The health literacy of the experimental group before and after participating in the program was mostly at the interaction level of 54.05% and 62.16%, respectively, which increased from before participating in the activity by 8.11%. The basic level and dietary and exercise behaviors of the experimental group were significantly different (p<0.01), while those of the control group were not significantly different.

Conclusion: All relevant agencies should be aware of the importance of body mass index. To reduce the problem of those who are overweight and those who are sick with chronic non-communicable diseases. And can use the research results to develop various programs to suit people who want to reduce their body mass index.
