Exposure to oil pollution and maternal outcomes: The Niger Delta prospective cohort study.

BACKGROUND: Maternal exposure to oil pollution is an important public health concern. However, there is a dearth of literature on the effects of maternal exposure to oil pollution on maternal outcomes in the Niger Delta region of Nigeria. This study was therefore designed to determine the effect of maternal exposure to oil pollution on maternal outcomes in the Niger Delta region of Nigeria. METHODS: Prospective cohort study design involving 1720 pregnant women followed from pregnancy to delivery was conducted. The participants were 18-45 years old at a gestational age of less than 17 weeks, who attended randomly selected health facilities in the areas with high exposure and low exposure to oil pollution in the Niger Delta, Nigeria. Data were collected using an interviewer-administered questionnaire and review of medical records from April 2018 to April 2019. Multivariate log-binomial model was used to examine the effect of maternal exposure to oil pollution on the risk of adverse maternal outcomes adjusting for sociodemographic, maternal and lifestyle characteristics. RESULTS: A total of 1418 women completed the follow-up and were included in the analysis. Women in high exposure areas had a higher incidence of premature rupture of membrane (PROM), caesarean section (CS) and postpartum haemorrhage (PPH) compared to women in areas with low exposure to oil pollution. After adjusting for cofounders, women in high exposure areas also had a higher risk of PROM (ARR = 1.96; 95% CI: 1.24-3.10) and PPH (ARR = 2.12; 95% CI: 1.28-3.36) in Model I-III when compared to women in areas with low exposure to oil pollution. However, pregnancy-induced hypertension and CS had no association with maternal exposure area status to oil pollution. CONCLUSION: Women in high exposure areas are at a higher risk of PROM and PPH. This calls for policies and intervention toward reducing maternal exposure to oil pollution in the Niger Delta region of Nigeria.

Intimate partner violence among pregnant women attending antenatal care services in the rural Gambia.

BACKGROUND: Intimate partner violence (IPV) refers to any behavior by either a current or ex-intimate partner or would-be rejected lover that causes physical, sexual, or psychological harm. It is the most common form of violence in women's lives. According to a World Health Organization report, about 1 in 3 women worldwide experience at least one form of IPV from an intimate partner at some point in her life. In the Gambia, about 62% of pregnant women experience at least one form of violence from an intimate partner. IPV has severe physical and mental health consequences on a woman ranging from minor bodily injury to death. It also increases the risk of low birth weight, premature delivery, and neonatal death. METHODS: A health facility-based cross-sectional study design was carried out to assess the magnitude and factors associated with intimate partner violence among pregnant women seeking antenatal care in the rural Gambia. The study enrolled 373 pregnant women, and a multi-stage sampling technique was used to select the respondents. An interviewer-administered structured questionnaire was used to obtain information from the study participants. The collected data were analyzed using SPSS Ver.22. Bivariate and multivariate logistic regression were used to determine the association between dependent and independent variables. Odds ratio with 95% confidence interval (CI) was computed to determine the presence and strength of associated factors with IPV. RESULT: The study reveals that the prevalence of IPV in The Gambia is 67%, with psychological violence (43%) being the most common form of IPV reported by the respondents. The multivariate logistic regression result reveals that being aged 35 years or older [AOR 5.1(95% CI 1.5-17.8)], the experience of parents quarreling during childhood [AOR 1.7(95% CI 1.0-2.75)], and having cigarette smoking partners [AOR 2.3 (95% CI 1.10-4.6)] were significantly associated with IPV during pregnancy. CONCLUSION: This study has demonstrated that all forms of IPV in rural Gambia are frequent. Women older than 35 years, had experienced parents quarreling, had a partner who smoked, and a partner who fight with others were more likely report IPV compared to other pregnant women in the study. We recommend that IPV screening should be included as an integral part of routine antenatal care services in The Gambia. Community-based interventions that include indigenous leaders, religious leaders, and other key stakeholders are crucial to create awareness on all forms of IPV and address the risk factors found to influence the occurrence of IPV in rural Gambia.

Miscarriage, stillbirth, and infant death in an oil-polluted region of the Niger Delta, Nigeria: A retrospective cohort study.

OBJECTIVE: To determine the association between oil pollution and miscarriage, stillbirth, and infant death in the Niger Delta region of Nigeria. METHODS: A retrospective cohort study was undertaken of pregnant women (aged 18-45 years) who attended selected health facilities in regions with high and low exposure to oil pollution from May 14, 2018, to September 27, 2018. A multistage sampling technique was used to randomly select a representative of women with high and low exposure to oil pollution. An interviewer-administered questionnaire was used for data collection. Bivariate and multivariable logistic regression analyses were employed to adjust for confounding factors of miscarriage, stillbirth, and infant death. RESULTS: In total, 1564 pregnant women were included in the study. Women with high exposure to oil pollution were more likely to experience stillbirth (odds ratio [OR] 1.806; 95% confidence interval [CI] 1.177-2.770) and infant death (OR 2.162; 95% CI 1.409-3.317). However, after adjusting for potential confounders, only infant death was associated with high exposure (adjusted OR 1.843; 95% CI 1.146-2.962). No association was found between miscarriage and high exposure to oil pollution. CONCLUSION: Women with high exposure to oil pollution are at higher risk of infant death.

Perception Determinants of Women and Healthcare Providers on the Effects of Oil Pollution on Maternal and Newborn Outcomes in the Niger Delta, Nigeria.

PURPOSE: This qualitative study examined the perception determinants of women and their local healthcare providers on exposure to oil pollution and its adverse effects on maternal and newborn outcomes in selected communities with history of oil spillage and gas flaring in the Niger Delta region of Nigeria. PARTICIPANTS AND METHODS: Thirty-nine participants were used in this study, which included community women leaders (n=2), women of reproductive ages (n=32) and healthcare providers (n= 3 female nurses and 2 male doctors) in the selected communities in the Niger Delta region of Nigeria. The participants were chosen through purposive sampling. Focus group discussions (FGDs) and in-depth interviews (IDIs) were conducted among the participants and recorded in line with research protocols. The recordings of the FGDs and IDIs were transcribed, coded and analysed using Nvivo 10. RESULTS: Four major themes emerged relating to the perception determinants of women and healthcare workers on the effects of oil pollution on maternal and newborn outcomes. The first theme relates to the fact that personal experiences influence risk perception. The second theme associated perception with cultural norms, values and practices. The third theme shows that perception is influenced by the level of environmental threat or hazard, while the fourth theme borders around the influence of hospital-related factors on risk perception. CONCLUSION: The study strongly suggested that both women and local healthcare providers perceived that oil pollution could have adverse effects on maternal and newborn outcomes. However, their perceptions were influenced by the cultural beliefs of the people, individual experiences, environmental and hospital-related factors. We believe that increasing awareness on the importance of attending antenatal care during pregnancy, making hospital charges affordable for pregnant women, and general environment conduciveness will improve maternal and newborn health in communities affected by oil pollution in the Niger Delta region.

Breast Cancer Knowledge Assessment of Health Workers in Ibadan, Southwest Nigeria.

PURPOSE: Breast cancer is the most common cancer among women, and in low- to middle-income countries late-stage diagnosis contributes to significant mortality. Previous research at the University College Hospital, a tertiary hospital in Ibadan, Nigeria, on social factors contributing to late diagnosis revealed that many patients received inappropriate initial treatment. METHODS: The level of breast cancer knowledge among health practitioners at various levels of the health system was assessed. We developed a tool tailored to local needs to assess knowledge of symptoms, risk factors, treatments, and cultural beliefs. The recruitment included doctors, nurses, and pharmacists in public hospitals, physicians and pharmacists in private practice, nurses and health care workers from primary health care centers, community birth attendants, and students in a health care field from state schools. RESULTS: A total of 1,061 questionnaires were distributed, and 725 providers responded (68%). Seventy-eight percent were female, and > 90% were Yoruba, the dominant local ethnic group. The majority were Christian, and 18% were Muslim. Median knowledge score was 31 out of 56, and the differences in scores between health care worker types were statistically significant (P < .001). Nearly 60% of the participants believed breast cancer is always deadly. More than 40% of participants believed that keeping money in the bra causes breast cancer, and approximately 10% believed that breast cancer is caused by a spiritual attack. CONCLUSION: Our questionnaire revealed that, even at the tertiary care level, significant gaps in knowledge exist, and knowledge of breast cancer is unacceptably low at the level of community providers. In addition to efforts aimed at strengthening health systems, greater knowledge among community health care workers has the potential to reduce delays in diagnosis for Nigerian patients with breast cancer.

A longitudinal study of the prevalence and characteristics of breast disorders detected by clinical breast examination during pregnancy and six months postpartum in Ibadan, Southwestern Nigeria.

BACKGROUND: Breast disorders cause great anxiety for women especially when they occur in pregnancy because breast cancer is the most common cause of cancer related deaths in women. Majority of the disorders are Benign Breast Diseases (BBD) with various degrees of associated breast cancer risks. With increasing breast cancer awareness in Nigeria, we sought to determine the prevalence and characteristics of breast disorders among a cohort of pregnant women. METHODS: A longitudinal study of 1248 pregnant women recruited in their first trimester- till 26 weeks gestational age consecutively from selected antenatal clinics (ANCs), in Ibadan, Southwest Nigeria. A pretested interviewer- administered questionnaire was used to collect information at recruitment. Clinical Breast Examination (CBE) using MammaCare® technique was performed at recruitment and follow up visits at third trimester, six weeks postpartum and six months postpartum. Women with breast disorders were referred for Breast Ultrasound Scan (BUS) and those with Breast Imaging Reporting and Data System (BIRADS) ≥4 had ultrasound guided biopsy. Statistical analysis was performed using Stata version 14. RESULTS: Mean age of participants was 29.7 ± 5.2 years and mean gestational age at recruitment was 20.4 ± 4.4 weeks. Seventy-two participants (5.8%) had a past history of BBD and 345 (27.6%) were primigravidae. Overall, breast disorder was detected among 223 (17.9%) participants and 149 (11.9%) had it detected at baseline. Findings from the CBE showed that 208 (69.6%) of 299 breast disorders signs found were palpable lumps or thickenings in the breast, 28 (9.4%) were persistent pain, and 63 (21.1%) were abscesses, infection and mastitis. Twenty out of 127 (15.7%) participants who had BUS performed were classified as BIRADS ≥3. Lesions found by BUS were reactive lymph nodes (42.5%), prominent ducts (27.1%), fibroadenoma (9.6%), breast cysts (3.8%) and fibrocystic changes (2.5%). No malignant pathology was found on ultrasound guided biopsy. CONCLUSIONS: Breast lump is a major breast disorder among pregnant women attending antenatal clinics in Ibadan. Routine clinical breast examination and follow up of pregnant women found with breast disorders could facilitate early detection of pregnancy associated breast cancer in low resource settings.

Inherited Breast Cancer in Nigerian Women.

PURPOSE: Among Nigerian women, breast cancer is diagnosed at later stages, is more frequently triple-negative disease, and is far more frequently fatal than in Europe or the United States. We evaluated the contribution of an inherited predisposition to breast cancer in this population. PATIENTS AND METHODS: Cases were 1,136 women with invasive breast cancer (mean age at diagnosis, 47.5 ± 11.5 years) ascertained in Ibadan, Nigeria. Patients were selected regardless of age at diagnosis, family history, or prior genetic testing. Controls were 997 women without cancer (mean age at interview, 47.0 ± 12.4 years) from the same communities. BROCA panel sequencing was used to identify loss-of-function mutations in known and candidate breast cancer genes. RESULTS: Of 577 patients with information on tumor stage, 86.1% (497) were diagnosed at stage III (241) or IV (256). Of 290 patients with information on tumor hormone receptor status and human epidermal growth factor receptor 2, 45.9% (133) had triple-negative breast cancer. Among all cases, 14.7% (167 of 1,136) carried a loss-of-function mutation in a breast cancer gene: 7.0% in BRCA1, 4.1% in BRCA2, 1.0% in PALB2, 0.4% in TP53, and 2.1% in any of 10 other genes. Odds ratios were 23.4 (95% CI, 7.4 to 73.9) for BRCA1 and 10.3 (95% CI, 3.7 to 28.5) for BRCA2. Risks were also significantly associated with PALB2 (11 cases, zero controls; P = .002) and TP53 (five cases, zero controls; P = .036). Compared with other patients, BRCA1 mutation carriers were younger ( P < .001) and more likely to have triple-negative breast cancer ( P = .028). CONCLUSION: Among Nigerian women, one in eight cases of invasive breast cancer is a result of inherited mutations in BRCA1, BRCA2, PALB2, or TP53, and breast cancer risks associated with these genes are extremely high. Given limited resources, prevention and early detection services should be especially focused on these highest-risk women.

Social barriers to diagnosis and treatment of breast cancer in patients presenting at a teaching hospital in Ibadan, Nigeria.

Globally, breast cancer is the most frequent malignancy in women, and stage at diagnosis is a key determinant of outcome. In low- to middle-income countries, including Nigeria, advanced stage diagnosis and delayed treatment represent a significant problem. That social barriers contribute to delay has been noted in previous research; however, few specific factors have been studied. Using semi-structured interviews, this study identifies social barriers to diagnosis and treatment for patients who presented at University College Hospital Ibadan, Nigeria. Transcripts from the interviews were coded and analysed thematically. Thirty-one patients and five physicians were interviewed. The median age of patients was 51 (range: 28 to above 80), 83% were Christian and 17% were Muslim. Preliminary analysis showed that delays in diagnosis reflected a lack of education as well as the utilisation of non-physician medical services such as pharmacists. Delays in treatment were often due to fear of unanticipated surgery and cost. The majority of women did not know the cause of their breast cancer, but some believed it was caused by a spiritual affliction. This study suggests that further education and awareness of breast cancer for both patients and providers is needed in order to increase early stage diagnosis.

Group psychological therapy in obstetric fistula care: a complementary recipe for the accompanying mental ill health morbidities?

The objective of this study is to determine the impact of group psychological therapy (GPT) on the mental health of obstetric fistula patients. It was a comparative pre and post intervention design. All patients had GPT prior to surgery and mental health assessment conducted before and after surgical repair. There was a significant reduction in proportion of those with severe mental health status after surgery. Specifically, the proportion of those with depression score of 4 and above reduced from 71.7% to 43.4%, and those with score of less than 4 increased from 28.3 to 56.6 percent. There was a significant reduction in those with very low self-esteem from 65.0% to 18.3%. Suicidal ideation reduced generally; severe (15.0 to 0%), moderate (16.7 to 5.0%) and mild (25.0 to 21.7%) and those without increased (43.3 to 73.3%). In conclusion, GPT is a useful adjunct to OF care as it improves their overall mental health status.

Bilateral double ureters with bladder neck diverticulum in a nigerian woman masquerading as an obstetric fistula.

A 43-year-old woman presented with 20-year history of leakage of urine per vaginam. She had one failed repair attempt. Pelvic examination with dye test showed leakage of clear urine suggestive of ureterovaginal fistula. The preoperative intravenous urogram revealed duplex ureter and cystoscopy showed normally cited ureteric orifices with two other ectopic ureteric openings and bladder diverticula. The definitive surgery performed was ureteric reimplantation (ureteroneocystostomy) of the two distal ureteric to 2 cm superiolateral to the two normal orifices and diverticuloplasty. There was resolution of urinary incontinence after surgery. Three months after surgery, she had urodynamic testing done (cystometry), which showed 220 mLs with no signs of instability or leakage during filling phase but leaked on coughing at maximal bladder capacity. This is to showcase some diagnostic dilemma that could arise with obstetric fistula, which is generally diagnosed by clinical assessment.

Theories of urinary incontinence causation: aetiological descriptions by sub-Saharan African women.

OBJECTIVE: To describe the perceived causes of urinary incontinence (UI) and factors associated with awareness of causes of UI among women in the community. STUDY DESIGN: Secondary analysis of data extracted from the Ibadan Urinary Incontinence Household Survey (IUIHS), a multi-stage community survey conducted among 5001 women in Nigeria. RESULTS: The mean age was 34.8 years (SD=14.2). The majority had at least secondary education and were currently married. Within this population, 13% had ever leaked urine. On their perception of possible aetiological factors of UI, 20.5% mentioned pelvic floor or bladder-related causes such as stress incontinence triggers and bladder problems; 14.6% mentioned uncontrollable factors such as medical comorbidity, age and prior surgery; 8.8% attributed the cause to being female; and 6.8% mentioned sex-related factors. Multiple logistic regression analysis revealed significantly lower odds of awareness of the aetiology of urinary incontinence among women aged less than 30 years, those with lower level of education, rural women, those with five or more children and women without history of urine leakage. CONCLUSIONS: The study shows a low level of awareness of possible cause of UI amongst women surveyed. We recommend health education and mobilization of women on the right aetiological factors of UI.

Pattern of mental ill health morbidities following hysterectomy for benign gynaecological disorders among Nigerian women.

OBJECTIVE: to compare the pre and post hysterectomy mental ill health (MIH) status and also, to determine whether there is any association with the surgical indication. METHODOLOGY: An observational study, conducted among women scheduled for hysterectomy at the University College Hospital, Ibadan from January till June 2005. The MIH morbidities were assessed using a validated general health questionnaire (GHQ) before and after the surgery by trained research assistant. The score of 4 and above was used as the cut off. Cross tabulations were performed to detect any association and also to compare pre and post hysterectomy mental health status. The level of statistical significance was set at P < 0.05. RESULTS: Of the 50 women recruited, 45 participated in the study. The age range of the participants was 35 to 63 years with a mean of 48.6 (SD = 0.6) years. Anxiety related disorder was present in 20 (44.4%), and depression in 3 (6.7%) before hysterectomy. Post surgery, there was significant increase in those with anxiety by 6.8% and a reduction in the proportion of depressive illness by 2.3%. Uterine fibroid as a preoperative diagnosis, had significant association among those with anxiety related disorder (68.4%) and depression (10.5%). CONCLUSION: This study suggests that mental ill health may complicates hysterectomy for benign uterine pathology among Nigerian women, and that anxiety related disorders increases after operation with the highest proportion in those with clinical diagnosis of Uterine Fibroid. We recommend adequate preoperative counseling using properly trained psychologists when affordable to minimize these morbidities.
