Background/Objectives: Unintended pregnancy is linked to an increased risk of subsequent unintended pregnancies, but its impact on contraceptive use and intention remains vastly understudied. This study assessed whether unintended pregnancy independently influences women's stages of behavior change for contraceptive use and the effectiveness of their chosen contraceptive methods. Methods: Using pooled data from three cross-sectional surveys of the Performance Monitoring and Accountability 2020 project in Nigeria, we analyzed responses from 8014 non-pregnant women aged 15-49 years nested within 892 communities. Multilevel multinomial logistic regression accounted for compositional and contextual factors. Results: Women with a mistimed pregnancy had higher odds of being in the contemplation stage of behavior change compared to those with an intended pregnancy (adjusted odds ratio [aOR] = 1.59, 95% confidence interval [CI] = 1.13-2.22), with a similar but non-significant trend for unwanted pregnancies (aOR = 1.46, 95% CI = 0.91-2.34). Mistimed and unwanted pregnancies were also linked to higher odds of being in the action stage (aOR = 2.17 and 1.85, respectively). Regarding contraceptive effectiveness, women with a mistimed pregnancy were more likely to use moderately effective methods (aOR = 1.47, 95% CI = 1.02-2.12) and highly effective methods (aOR = 2.45, 95% CI = 1.41-4.26). Unwanted pregnancies showed even stronger associations with highly effective methods (aOR = 4.03, 95% CI = 1.18-13.74). Community-level variability significantly influenced outcomes. Conclusions: Together, these findings underscore the importance of person-centered approaches and public health interventions tailored to stages of contraceptive behavior change, targeting both women and communities at high risk of unintended pregnancy.

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches

Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...

Regression Toward the Mean

Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...

Birth Control Methods01:22

Birth Control Methods

Vasectomy is a surgical form of male sterilization that involves severing and sealing the vasa deferentia, preventing sperm from mixing with semen during ejaculation. Because a vasectomy does not impact the testes' ability to produce testosterone, hormone levels, libido, and sexual function generally remain unchanged. While vasectomy is highly effective in preventing pregnancy, with a success rate near 99.85%, rare cases of recanalization (spontaneous reconnection) can occur. Although...

Observational Studies

Observational studies are a type of analytical study where researchers observe events without any interventions. In other words, the researcher does not influence the response variable or the experiment's outcome.
There are three types of observational studies – Prospective, retrospective, and cross-sectional.
Prospective Study
Prospective studies, also known as longitudinal or cohort studies, are carried out by collecting future data from groups sharing similar characteristics. One...

Longitudinal Research

Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...
