The effect of behavioural changes via text messaging on weight loss in women with overweight and obesity

This study examined the effectiveness of short message service (SMS)-based behavioral modifications combined with nutritional education on weight loss among women with overweight and obesity. Participants were divided into a control group receiving only nutritional education and an intervention group receiving both nutritional education and daily SMS reminders for 90 days. Data collection included demographic details, health status, anthropometric measurements, and responses to the Attitude Scale for Healthy Nutrition (ASHN), the Mediterranean Diet Adherence Scale (MEDAS), and the International Physical Activity Questionnaire (IPAQ). Surveys and measurements were conducted at the start, after four weeks, and at twelve weeks. The final analysis involved 62 women, with a median age of 43 years. The intervention group had 29 participants, while the control group had 33. Results showed a significant reduction in body weight and BMI from baseline to 12 weeks. However, no significant differences in weight loss were observed between the groups. Changes in MEDAS scores varied, with an initial increase in the intervention group and a decrease in the control group. By week 12, MEDAS scores were similar in both groups. Although group differences were not statistically significant, the study highlights the potential of SMS as a motivational tool for healthy eating behaviors.
