Figures
- Figure 1:
Creation of the study cohort.*Restricted to urban and suburban areas in Toronto and surrounding communities (Burlington, Oakville, Mississauga, Brampton, Richmond Hill, Vaughan, Markham, Pickering, Ajax, Whitby and Oshawa). †Among women who immigrated to Canada in 1985 or later. Values in brackets reflect the no. of women who gave birth. OHIP = Ontario Health Insurance Plan.
- Figure 2:
Mean daily outdoor air temperature over the 30-day period before screening for gestational diabetes mellitus (GDM) and corresponding crude prevalence (95% confidence interval [vertical bars]) of GDM. Data are shown for pregnancies (n = 555 911) that occurred in the Greater Toronto Area in Ontario, from 2002 to 2014. Crude and age-adjusted prevalences for GDM per 1°C rise in 30-day mean temperature were highly correlated (R2 = 0.997). Coldest (blue) to moderate (green) to hottest (red) temperatures are shown on the solid line. CI = confidence interval.
- Figure 3:
Relative odds of gestational diabetes mellitus (GDM; unadjusted [black squares] and adjusted [red circles] odds ratios [95% CI]) per 10°C increase in mean daily outdoor air temperature over a 30-day period before screening for GDM. The top 2 models (green text) include all pregnancies, by the 30-day period before 27 weeks gestation and the 30-day period before the actual date of screening, adjusted for maternal age, parity, income quintile, world region and year. The middle 2 models (blue text) include only women with 2 consecutive pregnancies, adjusted for maternal age and parity for each pregnancy. The bottom model (orange text) includes only the subgroup of women with serum glucose results for the 50-g glucose challenge test, adjusted for maternal age, parity, income quintile, world region and year. CI = confidence interval, OR = odds ratio.
