Objective: To investigate the current status of sexual function and its influencing factors among pregnant women, so as to provide the reference for improving sexual health among pregnant women. Methods: From January to July 2025, pregnant women attending regular prenatal check-ups at Shanxi Children's Hospital (Shanxi Maternal and Child Health Hospital), were selected as study participants using a convenience sampling method. Information on sociodemographic, pregnancy-related conditions, and sexual activity during pregnancy was collected through questionnaire surveys. Sexual function status over the past four weeks was assessed using the Chinese version of the Female Sexual Function Index. A multiple linear regression model was employed to analyze the influencing factors for sexual function among pregnant women. Results: A total of 424 pregnant women were surveyed, with the majority aged 30-<35 years (211 cases, 49.76%). Among them, 72 were in the first trimester (16.98%), 200 in the second trimester (47.17%), and 152 in the third trimester (35.85%). The overall sexual function score among pregnant women was (17.85±6.46) points. Scores for the six domains, desire, arousal, lubrication, orgasm, satisfaction, and pain were (3.23±0.78) (2.21±1.20) (2.76±1.63) (2.95±1.68) (4.14±1.08) (2.56±1.96) points, respectively. Multiple linear regression analysis revealed that cohabitation with a companion (β'=0.124), stage of pregnancy (third trimester, β'=-0.360), and changes in sexual practices or positions during pregnancy (β'=0.164) were statistically associated with sexual function scores among pregnant women (all P<0.05). Conclusions Sexual function declines among pregnant women, with mean scores across all domains falling below the critical threshold. Cohabitation with a companion and appropriate adjustments in sexual practices or positions according to the stage of pregnancy may improve sexual function among pregnant women.

Objective To investigate the relationship between the insulin sensitivity and the thyroid hormone levels in the pa‐tients with type 2 diabetes mellitus(T2DM ) to provide reference for the clinical diagnosis and treatment .Methods 86 patients with T2DM were selected as the observation group and contemporaneous 72 healthy persons were selected as the control group .All pa‐tients were detected the fasting plasma glucose (FPG) ,oral glucose tolerance test postprandial 2 h blood glucose (2 h PG) and thy‐roid hormons including free tetraiodothyronine (FT4) ,free triiodothyronine (FT3) and thyroid stimulating hormone (TSH) .The insulin sensitivity index (ISI) was calculated .The relationship between the insulin sensitivity with thyroid hormone levels was ana‐lyzed .Results FT3 ,FT4 ,FT3 /FT4 ,HOMA‐IR and ISI in the observation group were (4 .82 ± 1 .13) pmol /L ,(13 .12 ± 4 .36) pmol /L 0 .39 ± 0 .08 ,2 .94 ± 0 .37 and -5 .18 ± 0 .82 respectively ,which showing statistically significant differences compared with those in the control group(P<0 .05) ,the TSH level in the observation group was (2 .51 ± 1 .03) mU /L ,the difference between the two groups was not statistically significant (P> 0 .05);HOMA‐IR and FT3 had a negative correlation (r= -0 .543 ,P=0 .000) ,HOMA‐IR and FT4 had a positive correlation (r=0 .611 ,P=0 .000) ,ISI was positively correlated with FT3 (r=0 .551 ,P=0 .001) and negatively correlated with FT 4 (r= -0 .599 ,P=0 .000) .Conclusion The thyroid hormone levels are closely corre‐lated with the insulin sensitivity ,the thyroid hormone levels may be the partial pathological causes of T 2DM pathogenesis .
