Social determinants of delivery mode in Jiangsu, China

Factors associated with urinary retention after vaginal delivery under intraspinal anesthesia: a path analysis model

INTRODUCTION AND HYPOTHESIS

Women who have intraspinal anesthesia for delivery are more likely to experience postpartum urinary retention (PUR), which, if not recognized and treated promptly, can result in long-term urinary dysfunction. Many factors influencing PUR have been proposed, but no study has been conducted to investigate the relationship between them. This study is aimed at determining the influencing factors of PUR and to explore the relationship between them.

METHODS

A prospective, cross-sectional survey using self-made questionnaires was conducted among 372 puerperae in a Grade A hospital in Guangzhou, China, from April to September 2022. SPSS25.0 and AMOS24.0 were used for data analysis, and a path analysis model was established to determine the relationship between the influencing factors.

RESULTS

The incidence of PUR was 49.85%. Residence, the level of postpartum pain, and the change of postnatal urination position had a direct effect on PUR. Episiotomy and analgesic duration have both direct and indirect effects on PUR. Forceps delivery, perineal edema and oxytocin had an indirect effect on PUR. Variables could influence the occurrence of PUR by mediating the analgesic duration, episiotomy, postpartum pain level, and postnatal urination position changes.

CONCLUSIONS

This study provides an empirical model to illustrate the relationship between PUR and related factors in women who delivered under intraspinal anesthesia. In future management, more attention should be paid to women who live in cities, have higher levels of postpartum pain, longer analgesic duration, higher grade of perineal edema, and received episiotomy, forceps delivery, and oxytocin during labor.

The prevalence, associated factors, and impact of urinary incontinence in pregnant and postpartum women in Nanjing, China: A cross-sectional study

Objective

Urinary incontinence (UI) is highly prevalent in antenatal and postnatal women while the prevalence of UI varied largely from 3.84% to 38.65%. This study was to assess the prevalence of UI, the associated factors, and the impact of UI on daily life in pregnant and postpartum women in Nanjing, China.

Methods

The prevalence of UI and the impact of UI on life were assessed by the validated Chinese version of International Consultation on Incontinence Questionnaire-urinary incontinence-short form and the validated Chinese version of urinary incontinence quality of life. The associated factors were estimated by using logistic regression analysis.

Results

UI affected 37.80% of pregnant women and 16.41% of postpartum women of the study population. Among the pregnant participants, the prevalence rates of stress UI, urge UI, and mixed UI were 25.77%, 4.47%, and 7.10%, respectively. Among the postpartum women, the prevalence rates of stress UI, urge UI, and mixed UI were 11.15%, 1.92%, and 2.69%, respectively. In both pregnant women and postpartum women, vaginal delivery had significantly increased the odds of reporting UI (p=0.007, p=0.003, respectively). The impact of UI on daily life was significantly greater in postpartum women compared to pregnant women especially in social embarrassment (p=0.000).

Conclusion

The prevalence rates of UI were high in pregnant women in Nanjing, China. Vaginal delivery significantly increased odds of reporting UI. UI has a great impact on pregnant and postpartum women's life, especially in social embarrassment.

Outcomes and risk factors for failed trial of labor after cesarean delivery (TOLAC) in women with one previous cesarean section: a Chinese population-based study

Objective

To evaluate the outcomes and risk factors for trial of labor after cesarean delivery (TOLAC) failure in patients in China.

Methods

Consecutive patients who had a previous cesarean delivery (CD) and attempted TOLAC were included from 2014 to 2020. Patients who successfully delivered were classified into the TOLAC success group. Patients who attempted TOLAC but had a repeat CD due to medical issues were classified into the TOLAC failure group. Multiple logistic regression analyses were performed to examine the risk factors for TOLAC failure.

Results

In total, 720 women who had a previous CD and attempted TOLAC were identified and included. The success rate of TOLAC was 84.2%(606/720). Seven patients were diagnosed with uterine rupture, none of whom underwent hysterectomy. Multiple logistic regression analysis showed that the induction of labor (OR = 2.843, 95% CI: 1.571–5.145, P < 0.001) was positively associated with TOLAC failure, but the thickness of the lower uterine segment (LUS) (OR = 0.215, 95% CI: 0.103–0.448, P < 0.001) was negatively associated with TOLAC failure.

Conclusions

This study suggested that TOLAC was effective in decreasing CD rates in the Chinese population. The induction of labor was positively associated with TOLAC failure, but the thickness of the LUS was negatively associated with TOLAC failure. Our findings need to be confirmed in larger samples with patients of different ethnicities.

Hukou-based rural-urban disparities in maternal health service utilization and delivery modes in two Chinese cities in Guangdong Province

BACKGROUND

Most existing research on rural-urban health inequalities focuses on disparities in service access and health outcomes based on region. This paper examines rural-urban disparities in maternal healthcare utilization and delivery modes based on household registration (hukou) status to understand the role of state institutions in producing healthcare disparities in China.

METHODS

Utilizing administrative data from the Public Maternal Health Insurance scheme, we analyzed 54,733 live births in City A (2015-2019) and 25,849 live births in City B (2018-2019) in Guangdong Province in China. We constructed regression models using hukou status (rural versus urban) as the explanatory variable.

RESULTS

While there is no statistically significant difference in rural and urban mothers' probability of obtaining the minimum recommended number of prenatal care checkups in City A (OR = 0.990 [0.950, 1.032]), mothers with rural hukou status have a lower probability of obtaining the minimum recommended number of visits in City B than their counterparts with urban hukou (OR = 0.781 [0.740, 0.825]). The probability of delivering in tertiary hospital is lower among mothers with rural hukou than among those with urban hukou in both cities (City A: OR = 0.734 [0.701, 0.769]; City B: OR = 0.336 [0.319, 0.354]). Mothers with rural hukou are more likely to have a Cesarean section than those with urban hukou in both cities (City A: OR = 1.065 [1.027, 1.104]; City B: OR = 1.127 [1.069, 1.189]). Compared with mothers with urban hukou, mothers with rural hukou incurred 4 % (95 % CI [-0.046, -0.033]) and 9.4 % (95 % CI [-0.120, -0.068]) less in total medical costs for those who delivered via Cesarean section and 7.8 % (95 % CI [-0.085, -0.071]) and 19.9 % (95 % CI [-0.221, -0.177]) less for those who delivered via natural delivery in City A and City B, respectively.

CONCLUSIONS

Rural hukou status is associated with younger age, no difference or lower probability of having a minimum number of prenatal checkups, higher likelihood of delivering in nontertiary hospitals, increased Cesarean delivery rates, and lower medical cost for delivery in these two Chinese cities. Evaluating how hukou status influences maternal healthcare in Chinese cities is important for devising targeted public policies to promote more equitable maternal health services.
