Abstract
Type 2 diabetes is a growing public health problem globally, nationally, and locally in Nong Bua Subdistrict, Phu Ruea District, Loei Province, where pre-diabetes among working-age adults has risen sharply, while studies applying all six pillars of lifestyle medicine in rural communities remain limited.
To evaluate the effects of a lifestyle medicine-based behavior modification program on fasting plasma glucose (FPG), diabetes knowledge, self-efficacy, and preventive behaviors among pre-diabetic working-age adults.
A quasi-experimental two-group pretest-posttest study enrolled 40 pre-diabetic adults aged 35–59 years, allocated to an experimental (n = 20) and a control group (n = 20) by village-level cluster allocation (not individual randomization). The experimental group received a 20-week six-pillar program; the control group received usual care. Data were analyzed using descriptive statistics, paired t-test, and independent t-test, with Shapiro-Wilk normality testing and Cohen's d effect sizes.
Post-intervention, the experimental group's knowledge rose from 11.25 to 17.45,
self-efficacy from 62.35 to 98.75, preventive behavior from 74.25 to 128.45, and FPG fell from 112.45 to 98.35 mg/dL. After the intervention the experimental group scored significantly higher than the control group on all measures and had significantly lower FPG (p < .001).
In total, 85.0% returned to normal FPG.
The program appears to improve knowledge, self-efficacy, preventive behavior, and FPG. Given the small sample and quasi-experimental design, findings should be interpreted cautiously and confirmed in larger studies before scale-up.
