Caesarean section is a crucial surgical intervention in obstetric care [1]-[3]. While it can prevent complications associated with vaginal delivery, it remains a major procedure carrying risks for both mother and newborn [3]-[7]. Among factors influencing surgical outcomes, anxiety—whether as a personality trait or an acute preoperative reaction—plays a significant role [1]-[3][5]-[8]. Preoperative anxiety is a transient emotional state characterized by tension and apprehension, particularly common in obstetric procedures compared to general surgery [9]-[13]. This public health concern shows considerable global variation, with reported prevalence rates ranging from 11% to 92.6% across different regions and contexts [8][10][11][14]-[17].

Studies have documented rates of 23.2% in Thailand, 55% - 63.54% in India, 67% in England, 62% - 72.7% in Pakistan, 51.81%-70.6% in Nepal, and 40.6% in Sri Lanka [10]. In Africa, preoperative anxiety prevalence remains high, reaching 57.1% among women undergoing elective obstetric and gynecological surgeries in Ethiopia, 41.0% for elective caesarean sections in Sudan, and 51% - 90% in Nigeria [10][18][19].

Research has identified several factors associated with preoperative anxiety in caesarean sections, including fear of postoperative pain, concerns about mortality, family-related worries, and insufficient information about anesthesia and surgical procedures [1][8]-[10][20]-[22]. Other contributing factors include surgery type (emergency vs. elective), previous anesthesia and surgical experiences, social support quality, and socioeconomic status [5][10][11][14][19][21].

The clinical significance of preoperative anxiety lies in its adverse effects on both maternal and neonatal outcomes [1][7][10][17][22]-[24]. Maternal complications may include hypertension, impaired wound healing, and inadequate pain management often leading to analgesic overuse [8][21][23]. For newborns, maternal preoperative anxiety associates with low birth weight, respiratory distress, and increased risk of future mental health disorders [1][7][17][20][25].

Despite extensive global research on preoperative anxiety in caesarean sections, knowledge gaps persist regarding its prevalence and associated factors in resource-limited countries like Cameroon. This study therefore aimed to assess the prevalence and identify factors associated with preoperative anxiety among women undergoing caesarean section in three hospitals in Yaounde, Cameroon.

Of 205 initially enrolled participants, 46 were excluded due to incomplete questionnaires, yielding a final sample of 159 participants for analysis.

Sociodemographic characteristics (Table 1) showed that most participants were aged ≤30 years (66.0%), single (43.4%), and had secondary (50.3%) or university education (43.4%). Employment distribution included private sector (30.8%), public sector (23.9%), students (24.5%), and unemployed (20.7%). Most were tenants (82.3%).

Table 1. Sociodemographic profile of participants.

Clinical profile (Table 2) revealed a preoperative anxiety prevalence of 86.8% (n = 138). Emergency caesarean sections accounted for 69.2% of procedures, and 31.5% of participants had a history of obstetric complications.

Table 2. Clinical profile.

Factors associated with preoperative anxiety (Table 3) identified several significant predictors through multivariate analysis. Age ≤30 years, student status, current obstetric complications, financial concerns, fear of complications, and fear of death increased anxiety risk. History of caesarean section and cohabiting marital status showed protective effects. Adequate procedural information and spousal involvement were significant protective factors.

This study reveals a high prevalence of preoperative anxiety (86.8%) among women undergoing caesarean section in Yaounde, Cameroon, consistent with rates reported in Nigeria (90%) but higher than findings from Thailand (23.2%) and England (67%) [18][19]. This elevated prevalence likely reflects the convergence of multiple risk factors in our study context.

Younger age (≤30 years) associated with higher anxiety, aligning with findings from Indonesia [18] and possibly reflecting greater emotional maturity and coping capacity with increasing age [5][6][8][9][13][18]. Socioeconomic factors significantly contributed to anxiety, with only 54.7% of participants having stable employment and 67.3% reporting financial concerns—particularly relevant in Cameroon’s evolving universal health coverage context [1][11]. The predominance of emergency caesarean sections (69.2%) due to obstetric complications represents another significant factor, consistent with studies showing higher anxiety risk in emergency versus elective procedures [1][11]. Moreover, inadequate patient-provider communication emerged as a critical concern, with only 20.8% of participants receiving sufficient procedural information and 34.6% reporting satisfactory communication with physicians. These findings mirror Ethiopian data, where 64.3% of patients received inadequate perioperative information [10]. This study also showed that patients’ high need for information about anesthesia and surgery was strongly associated with preoperative anxiety (OR = 4.68).

Other identified protective factors included complicated obstetric history, negative previous caesarean experiences, and fears of complications or death—align with existing literature [11][21][22]. This could be explained by the fact that familiarity with the procedure could enhance preparedness. Interestingly, while spousal involvement showed protective effects, general family support did not reach statistical significance, contrasting with studies from Spain and Indonesia [3][5][26].

This study has some limitations. Its cross-sectional design precludes causal inference. Potential selection bias may exist, and the timing of anxiety assessment immediately before surgery might inflate state anxiety measures.

This study demonstrates a high prevalence of preoperative anxiety among women undergoing caesarean section in Yaounde. Key modifiable factors include socioeconomic stability, spousal involvement, and quality patient-provider communication. These findings highlight the need for targeted interventions, particularly in emergency surgical contexts. Future research should focus on developing and evaluating context-appropriate strategies to reduce preoperative anxiety in resource-limited settings such as developing structured preoperative counseling programs or patient information leaflets that directly address patients specific fears with regards to surgery.
