Resumen

Introduction: Inadequate attendance at prenatal care (PNC) is a public health issue that affects maternal and perinatal outcomes. Objective: To identify and compare the factors associated with inadequate PNC attendance during the first and second trimesters of pregnancy in women receiving care at the Instituto Nacional Materno Perinatal (INMP) in Lima, Peru. Methods: An analytical cross-sectional study was conducted on 256 pregnant women with more than 26 weeks and 6 days of gestation who received care at the INMP. Adequate PNC was defined, according to the World Health Organization (WHO), as at least one visit before 13 weeks for the first trimester, and at least two visits between 13 and 26 weeks and 6 days for the second trimester. Structured surveys and a review of PNC records were conducted. Adjusted Poisson regression was applied to estimate prevalence ratios (PR) and 95% confidence intervals (95% CI), considering a p-value < 0.05 as statistically significant. Results: In the first trimester, being single (aPR=1.55; p=0.004), having a lower educational level (aPR=1.77; p=0.019), and receiving care from midwives (aPR=2.00; p<0.001) were associated with higher prevalence of inadequate attendance, while having a high-risk pregnancy was associated with lower prevalence (aPR=0.55; p<0.001). In the second trimester, higher prevalence persisted among single women (aPR=1.95; p=0.059) and those with lower education (aPR=2.19; p=0.026), as well as among women with three or more children (aPR=2.69; p=0.001). Conclusion: Factors associated with inadequate PNC attendance vary between trimesters, highlighting the need for targeted strategies to improve PNC coverage and adherence.
