Effect of educational intervention on the knowledge, attitude and practice of breast self-examination among female students at a private university in Southern Nigeria

INTRODUCTION

In Nigeria, breast cancer (BC), a disorder marked by the unchecked growth of breast cells, has been the commonest cancer among women in Nigeria. Breast self-examination (BSE) is one of the suggested methods for screening for the early diagnosis of breast cancer. However, studies have reported inadequate knowledge, negative attitudes and poor practices of BSE among undergraduate female students. The study was designed as an interventional study to examine the effect of educational intervention on knowledge, attitude and practice of breast self-examination among female students in a private university in southern Nigeria.

METHODS

This pretest posttest design study was carried out on 103 students of Novena University at baseline in 2022, which were chosen through the use of simple random sampling. A validated questionnaire with components on demographics, knowledge, attitude, and BSE practice was used to gather the data. After that, the students participated in three hourly sessions of an educational intervention for two weeks. A month later, the students' data were once again collected, and SPSS 20 software was used to evaluate the results using the mean, paired t test, and logistic regression at the P < 0.05 level of significance.

RESULTS

The mean age of the respondents was 22.37 ± 1.92 years. Only 53 (51.3%) were aware of BSE. The mean knowledge, attitude and practice of BSE at pretest significantly increased at posttest after the educational intervention (1.58 ± 1.48 vs. 4.31 ± 1.15, 2.37 ± 1.27 vs. 4.80 ± 0.49 and 1.97 ± 0.09 vs. 5.81 ± 3.26, respectively). Furthermore, age and family history of BC were predictors of knowledge (OR = 4.00 95% CI = 0.29-41.99, OR = 141, 95% CI = 0.15-13.18), attitude (OR = 2.39, 95% CI = 0.28-12.32, OR = 1.15, 95% CI = 0.24-8.34) and practice of BSE (OR = 2.66, 95% CI = 0.38-18.41, OR = 1.44, 95% CI = 0.24-8.34) respectively.

CONCLUSION

The findings showed that using an educational intervention strategy will improve the knowledge, attitude and practice of BSE among undergraduate students.

Age at last birth and risk of developing breast cancer: a meta-analysis

OBJECTIVES

Results from epidemiologic studies on age at last birth (ALB) and the risk of developing breast cancer were inconsistent. Therefore, we conducted this meta-analysis to evaluate the association between ALB and the risk of developing breast cancer quantitatively.

METHODS

Relevant articles published up to May 2019 were identified by searching systematically in PubMed, Web of Science, China National Knowledge Infrastructure, and Wan Fang Med Online. Pooled relative risks (RRs) with 95% confidence intervals (CIs) were calculated using a random-effects model. Dose-response relationship was assessed by restricted cubic spline model.

RESULTS

Fourteen studies with 132 133 cases and 1 314 005 participants were eligible for this meta-analysis. The pooled RR (95% CI) of breast cancer for the highest vs. the lowest stratification of ALB was 1.22 (1.04-1.42). In the subgroup analysis, significant positive associations were also found in studies conducted in Europe (RR: 1.21, 95% CI: 1.06-1.38), studies with results adjusted for parity (RR: 1.26, 95% CI: 1.04-1.54), and studies with results adjusted for age at first birth (RR: 1.37, 95% CI: 1.08-1.74). The results of the dose-response analysis indicated that the departure from linearity was NS between ALB and the risk of breast cancer (Pnonlinearity = 0.711), but the linear associations were NS.

CONCLUSION

This meta-analysis suggested that ALB was positively associated with the risk of breast cancer. The risk of developing breast cancer increased gradually with the ALB for women. Our findings may have implications for family planning.

Educational Intervention on Breast Self-Examination Behavior in Women Referred to Health Centers: Application of Health Belief Model

Introduction and aims:

Screening can play a major role in reducing deaths associated with cancer. Breast self-examination (BSE) is a cheap, non-complicated and non-invasive method for breast cancer screening. This study aimed to examine the effects of an educational intervention based on the health belief model (HBM) on BSE behavior in women referred to health centers in Fasa, Iran.

Methods:

This quasi-experimental study was conducted on 92 women, divided into an experimental and a control group. Data were collected using a validated questionnaire covering demographic characteristics, knowledge, HBM constructs and breast self-examination performance. An educational program was performed in five sessions through group discussion with questions and answers and training videos for participants in the experimental group. Questionnaires were filled before and three months after the intervention in the two groups. Data were analyzed with SPSS-22 software for descriptive and analytical statistics.

Results:

The results of this study showed that the mean scores for knowledge, HBM constructs and self-examination behavior in the experimental group were elevated compared to the control group after the intervention (P<0.001).

Conclusions:

Education based on the HBM is effective in promoting breast self-examination behavior. Thus development and implementation of training programs based on the model are proposed for officers involved in education and health promotion in Iran.
