BACKGROUND: Physical activity and nutrition interventions are the most important ways to prevent gestational diabetes. The purpose of the study was to determine the effect of healthy lifestyle intervention to promote preventive behaviors of gestational diabetes in the rural woman of Shoush city. MATERIALS AND METHODS: In an experimental study, 60 pregnant women were selected using simple random sampling and allocate into intervention group (n = 30) and nutrition program. The study was conducted from September to June 2018. The data were collected in baseline and 1 month and 3 months of follow-up phase and were analyzed using Chi-square test, repeated-measure test, and generalized linear model (GLM). The α = 0.05 was considered as significance. RESULTS: The mean age in the intervention and control group was 25.9 ± 5.6 and 27.2 ± 5.9, respectively. The GLM test showed a significant increase in the physical activity level and the mean of nutrition behaviors within the intervention group over time (P = 0.013). Further, based on the results of repeated-measure test, the mean of weekly MET-minute was increased in the intervention group in comparison to the control group at 1 month and 3 months of follow-up (P < 0.001). DISCUSSION AND CONCLUSION: The lifestyle interventions are appropriate programs to the reduction of the risk of development of gestational diabetes in pregnant women.

Background. Pre-diabetes is one of the most widespread epidemics in the world. Pre-diabetics are the most susceptible to diabetes. The prevalence of prediabetes status is higher than that of diabetes. Lifestyle modification at this stage may delay the onset of type 2 diabetes for ten years. The present study aims at determining the Dezful pre-diabetic women's experiences of diabetic preventive eating behaviors. Methods. The present study employed a directed qualitative content analysis (DQlCA) conducted in Dezful in 2020. The experiences of 41 pre-diabetic women aged 30-65 years and 9 health care providers (physicians, nutritionists, public health experts) were explained using the in-depth interviewing technique on the factors affecting diabetes preventive behaviors, including nutritional behaviors and physical activities, based on the constructions of the PEN-3 model. The participants were selected from Dezful health centers. Analysis of the qualitative data was done via a directed qualitative content analysis (DQlCA). Data validity was estimated by assessing acceptability, reliability, adaptability, and transferability. Results: the most appropriate and accessible way to promote diabetes prevention behaviors in pre-diabet-ics is to hold training classes with a health promotion approach implemented by health care providers. Conclusion. Pre-diabetic women have a variety of beliefs and habits influenced by awareness, food culture, and temporal and spatial constraints. By identifying the positive and negative beliefs affecting diet, researchers who want to promote the nutritional behavior of pre-diabetic women should correct and eliminate negative and inhibitory beliefs by targeting these beliefs, emphasizing positive and motivating beliefs. They also should use the mentioned points in their educational interventions. (Clin Diabetol 2021; 10
