Analyzed using Evidence Intelligence™

Text Messaging Program Shows Little Effect on Diabetes Risk Factors

Key finding

7/57 (12%) intervention and 6/56 (11%) control participants met the primary outcome (relative risk, 1.08; 95%CI, 0.63–1.85; p = 0.79).

This study evaluated a text messaging-based lifestyle support program for women with gestational diabetes. Results showed no significant differences in key health outcomes compared to a control group.

Plain-language summary

What this paper says

A plain-language read of the study's main message and where it applies.

Study focus

Clinical relevance

Understanding the effectiveness of lifestyle interventions for women with gestational diabetes is crucial, as these programs aim to improve health outcomes for both mothers and their infants. The lack of significant findings suggests that alternative approaches may be needed to support this population effectively.

Keep in mind

Small sample sizes may limit the power of the study. No significant differences were found in key health outcomes. The generalizability of findings may be restricted to similar populations.

Main Effects

12% of intervention participants met the healthy lifestyle outcome compared to 11% in the control group (RR 1.08, p = 0.79).

30% of intervention participants achieved weight goals versus 19% in the control group (RR 1.54, p = 0.17).

47% of intervention participants met physical activity goals compared to 63% in the control group (RR 0.72, p = 0.08).

Evidence Suggest

No significant improvement in healthy lifestyle outcomes (RR 1.08, p = 0.79).
Weight goal achievement was higher in the intervention group but not statistically significant (RR 1.54, p = 0.17).
Physical activity goal achievement was lower in the intervention group (RR 0.72, p = 0.08).

Who this applies to

Women diagnosed with gestational diabetes.
Participants in lifestyle intervention studies.

Keep in Mind

Results may not apply to all demographics of women with gestational diabetes.
Further research is needed to explore more effective interventions.
The study's findings may not reflect long-term outcomes beyond the intervention period.

Between the Lines
