Reference Design, Subjects (n) Population Intervention/Method Primary Outcome Main Results
Chen et al. [15] Prospective study, n = 13,475 Women from the Nurses’ Health Study II, 24–44 years, who reported having at least one singleton pregnancy lasting 6 months or more. Semiquantitative FFQ Gestational diabetes mellitus Intake of sugar-sweetened cola (≥5 servings/week) was positively associated with the risk of GDM (RR = 1.22; 95% CI 1.01–1.47). No significant association between SSB intake and “diet” beverages was found with the risk of GMD.
Gamba et al. [16] Cross-sectional study from NHANES survey, n = 1154 Pregnant women that completed dietary data AHEI-P to measure diet quality
24-h dietary recalls
Diet quality and total energy intake Every 12 oz. of SSBs consumed was associated with a 2.3 lower AHEI-P score (95% CI 1.6–2.9) and the consumption of 124 more calories.
Mijatovic-Vukas et al. [17] Meta-analysis, 40 studies, n = 30,871 Women with available diet or PA data during pre-pregnancy/early pregnancy Different dietary patterns or PA Gestational diabetes mellitus Higher SSB intake was associated with higher risk of GDM (RR ≥ 5 week = 1.23; 95% CI 1.05–1.45, p-value = 0.005).
The strongest association was observed for sugar sweetened cola (RR high vs. low intake = 1.29; 95% CI 1.07–1.55) but not for non-cola SSB (RR high vs. low = 0.99; 95% CI 0.78–1.25).
Wattar et al. [18] Multicenter, RCT, n = 1252
Meta-analysis, 2 RCT, n = 2397 women
