Low sleeping energy expenditure (SleepEE) in early pregnancy is associated with insulin resistance and low triiodothyronine (T3) concentrations.
For obese pregnant women, a lower-than-expected metabolic rate is linked to higher insulin resistance and lower thyroid hormone (T3) levels. This suggests that metabolic health issues may drive lower energy expenditure, contributing to weight gain risk.

Low SleepEE was associated with insulin resistance and low triiodothyronine concentrations (both P < 0.01).
Why this rating
Statistically significant associations found in a well-measured cohort.

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
