Research
(A.) Spousal support in Maternity care; focus on labour and delivery process; determinants and deterrents
{A Grant award received from to the Research and Ethics Committee (Bowen University Research Grant; BURG 2023), Bowen University, Iwo, Osun State.}
Globally, women in labor and delivery undergo enduring experiences of painful discomfort, fear, anxiety and tensions. In a bid to ameliorate these experiences, several studies have been conducted to establish the relationship between companionship by either medical personnel or spouses. These studies have shown that practices of professional support caregivers in labor known as “doula” when available and employed effectively to support women in labor produce an ameliorative effect on parturient pain. For purposes of this review, labour support is interpreted as a continuous non-medical care of a parturient woman. It includes physical comforting such as touching, massaging, bathing and emotional support such as companion, reassurance, encouragement, etc., These supports are either done by the medical personnel, family members, spouse or a hired hand (doula).
In different parts of the world, more especially in developed countries such as UK and Denmark, spousal participation is common practice during labour and delivery with about 95% attendance. Studies conducted in these developed countries shows that women who had continuous spousal labour support are reassured, comforted and emotionally encouraged to overcome pain associated with labour and delivery. Furthermore, a similar review has shown that women with continuous support by spouses also experience shorter labours, reduced need for oxytocin, anesthesia, analgesia, instrumental deliveries and decreased by 50% their chances of being admitted to a cesarean section.
Contrarily, in low-income countries like Nigeria, which is known to be a patriarchal male dominated society where pregnancy and child birth is regarded as exclusively women’s affairs, spousal participation in labour and delivery remains acutely low. Men traditionally do not accompany their wives for antenatal care and are mostly absent in the labour room during delivery, leaving their support roles to relatives and midwives. Thus, a question that readily comes to mind is what percentage of Nigerian spouses participate in labour and delivery? In an effort to resolve this question and bearing in mind that the extent of participation of spouses in labour and delivery in Nigeria in debatable, this narrative review will examine existing and accessible research literatures in relation to spousal participation in labour and delivery in Nigeria.
Equally, there are enormous benefits from psychosocial support especially when spouses are involved in their wives labour and delivery. Such benefits include emotional comfort, improved family communication and bonding, pain relief without analgesia and positive birth experience. Even though these benefits accrue from the participation of spouses in labor and delivery, it has not yet found its place in the Nigerian maternal health-care system. There is no gainsaying the fact that educational, social, religious and cultural factors have been seen to influence the participation of spouses in labour and delivery. On the other hand, education is seen as a very significant factor in determining spousal participation in delivery as an evident in the finding that most men that accompany their wives to the hospital in Nigeria are educated and are well-informed about the birth processes. This contrasts with the findings that uneducated spouses that constitute the higher percentage of spouses in Nigeria do not accompany their wives but hold the belief that they only have financial obligation towards childbirth. Nevertheless, education regardless of level attained, religious and cultural beliefs are held in very high esteem in Nigeria and persistently remain the most influential factors inhibiting spousal participation in labour and delivery.
There are beliefs that spousal presence will delay the labor process, causing more harm than good. Apparently, this belief is a myth that has been handed down from generations. Guided by this myth and coupled with the perception of wives that the presence of their spouses is not necessary or needed during labor, husbands refrain from participating in childbirth. Akin to this, a study conducted in the Northern part of Nigeria showed that male respondent held on to their cultural and religious beliefs that they had no role in labour and delivery since their religion and culture forbids a male presence during childbirth and their wives also share the same beliefs and views.
Aim and Objective
The aim of this research is to explore the extent of spousal participation in labour and delivery in Nigeria. To determine the determinants and the deterrents responsible for the current situation and to proffer possible solutions and provide recommendations that would encourage, promote, strengthen and institutionalize spousal participation in labour and delivery in Nigeria.
Materials and Methods:
A mixed research design is being used for this study. This will involve qualitative and quantitative analysis. The outcome variable will be the spousal attendance and eventual satisfaction enjoyed by patient as a result. The independent variables will be the patients and spousal social demographics factors (age, education, employment status, ethnicity, marital status, and religion)
Sample size will be calculated using fishers formular. N=Z2pq/d2
A previous study on spousal support in maternity care revealed a prevalence of 15%.
Participants and their husbands will be approached by the researcher requesting their participation in the study. Those who accept to participate will be given the study fact sheets and verbal explanations were also provided for clarity. Informed consent will be obtained through the signing of a short consent form by all participants and full confidentiality maintained. In addition, participants will be allowed to withdraw from the study at anytime.
Statistical analysis will be performed using SPSS 22. Differences in continuous variables will be analyzed with Student’s t-test for Normally distributed data and the Mann–Whitney U tests for skewed data. Differences in discontinuous variables will be analyzed by chi-square or Fisher’s exact test as appropriate. Relative risk(RR) with 95% confidence interval (CI) will be calculated for selected outcome parameters
Presently, ethical approval has been obtained and questionnaires are being administered for the conduct of the study.
(B.) The Prevalence of Gastro-esophageal Reflux Disease [GERD] Among Pregnant Women: A multi-center study
Most pregnant women have symptoms of gastroesophageal reflux disease (GERD), especially heartburn, at some point. These symptoms may start at any time during a pregnancy. And they often get worse throughout the pregnancy. Heartburn is common when you are pregnant. That’s because hormones cause the digestive system to slow down. The muscles that push food down the esophagus also move more slowly when you are pregnant. And as the uterus grows, it pushes on the stomach. This can sometimes force stomach acid up into the esophagus.
The prevalence of GERD among the pregnant women was 14.5% while that among the nonpregnant group was 9.7% and Pregnancy has a significant association with GERD, independent of the other risk factors. Another study on non pregnant adults found the prevalence of GERD to be 9.3% .
Prevalence of gastroesophageal reflux (GER) increases during pregnancy, due to several factors like decreased lower esophageal sphincter pressure, increased intra-abdominal pressure secondary to the enlarged gravid uterus and alteration in gastrointestinal transit.Most of the time, symptoms of heartburn improve after the baby is born.
Aim
To study the prevalence of gastroesophageal reflux amongst pregnant women. To identify the possible predisposing factors of GER in pregnancy.
Specific Objectives
To determine:
1. The prevalence of gastroesophageal reflux amongst pregnant women in the study area
2. The association between gestational age and symptoms of GER in pregnancy
3. The possible predisposing factors of GER in pregnancy.
Presently, ethical approval has been obtained and questionnaires are being administered for the conduct of the study.
(C.) Association between Helicobacter Pylori and Anaemia in Pregnancy.
Nearly 25 % of the world’s population suffers from anaemia, with pregnant women and children of pre-school age being the most affected. Worldwide, approximately 41% of women in sub-Saharan Africa, 23% in Latin America, 49% in Southeast Asia, and 60% in the Indian subcontinent of Asia are anaemic. Iron deficiency (ID) is the most common nutritional deficiency in the world and results in impairment of immune, cognitive and reproductive functions, as well as decreased work performance. Iron deficiency anemia (IDA) affects more than a billion people worldwide and contributes to up to 40% of maternal deaths in the developing countries.
Anaemia is defined as a condition in which the number of red blood cells (and consequently their oxygen carrying capacity) is insufficient to meet the body’s physiologic needs. Anemia in pregnancy is a condition of public health importance with a worldwide prevalence of 41.8%. It is seen in both the developed and developing countries. In America and Europe, the prevalence rates are 24.1% and 25.1%, respectively. In Africa, however, a prevalence of 48.1% was reported by the World Health Organization (WHO). Anaemia is estimated to wholly account for 20% of maternal death and partly contribute to 50% or more of all maternal deaths worldwide. IDA which is the most common cause of anaemia in pregnancy is responsible for 115,000 maternal deaths per year. Anaemia in developing countries has multifactorial aetiology which includes ID due to dependence on predominantly plant-based diets, from which adequate iron cannot be absorbed, hookworm infestation, malaria and other infections.
Helicobacter pylori (H. pylori) infection affects approximately half of the world population and it is more prevalent in developing countries. During the past decades, several reports indicated a correlation between H. pylori infection and various extragastric disorders including iron deficiency anaemia. Muhsen et al recommended the investigation of H. pylori infection as a potential factor that might play a role in the occurrence of anaemia in children and pregnant women. Furthermore, eradication of H. pylori infection has been recommended for patients with unexplained IDA. These recommendations are based on several studies that found a relationship between H. pylori and IDA. In a systematic review and meta-analysis of 12 case reports and series, 19 observational epidemiologic studies and six interventional trials, the prevalence of IDA in H. pylori-infected subjects was found to be higher than in uninfected ones. Several IDA mechanisms have been hypothesized in H. pylori infection, some of which are decreased mucosal iron absorption capacity due to low gastric pH, reduction of stomach vitamin C levels, bacterium-host competition for dietary iron supply, lactoferrin mediated iron sequestration by gastric H. pylori, increased hepatocytes hepcidin release in response to IL-6 production associated with H. pylori gastritis.
Justification
Few studies, if any, have sought to assess the relationship between H. pylori infection and IDA among pregnant women in Nigeria. Anaemia in pregnancy is a major public health challenge in sub-Saharan Africa contributing significantly to maternal and child morbidity and mortality. The prevalence of H. pylori infection in sub-Saharan Africa is reported to be high. Since H. pylori infection is treatable, the demonstration of its causative role in IDA amongst pregnant women will have important social-economic implications.
Aim
To assess the relationship between H. pylori infection and the occurrence of anaemia in pregnant women
Specific Objectives
To determine:
1. The prevalence of H. pylori infection among pregnant women in the study area
2. The association between H. pylori infection and the ocurrence of anaemia in pregnancy
3. The prevalence of anaemia among pregnant women in the study population.
Presently, ethical approval has been obtained and questionnaires are being administered for the conduct of the study.
(D.) The knowledge and willingness of postpartum mothers to perform genital cutting on their newborn females in Bowen University Teaching Hospital, Ogbomoso.
Female genital cutting is an unhealthy traditional practice inflicted on girls and women worldwide. Female genital cutting according to the World Health Organization is defined as all procedures which involve partial or total removal of the external female genitalia and/or injury to the female genital organs, whether for cultural or any other non-therapeutic reasons.
The prevalence depends on the level of education and the geographic location. Worldwide the highest prevalence is in Somalia and Djibouti.3 However, in Nigeria, FGM has the highest prevalence in the south-south (77%) (among adult women), followed by the south east (68%) and south west (65%), but practiced on a smaller scale in the northern part of the country. Nevertheless, Prevalence rates progressively decline in the younger population and 37% of circumcised women do not want female genital cutting to continue.
In Nigeria, the practice of female genital cutting has been longstanding, consequently it is seen as a fundamental violation of human rights, and has a strong association with cultural beliefs and perceptions.
Concerning the knowledge and perception of women about female genital cutting, it was observed that 61% of women who do not want the practice of female genital cutting said it was a bad and harmful tradition and 22% said it was against religion. The other reasons for not wanting the procedure included medical complications (22%), painful personal experience (10%), and the view that FGM is against the dignity of women (10%).However, there is still considerable support for the practice in areas where it is deeply rooted in local tradition.
There is need for abolition of this unhealthy practice. A multidisciplinary approach involving legislation, health care professional organizations, empowerment of the women in the society, and education of the general public at all levels with emphasis on dangers and undesirability of FGM is paramount.
Aim
The aim of this study was to ascertain the knowledge and willingness of postpartum mothers to perform genital cutting on their newborn females in Bowen University Teaching Hospital, Ogbomoso.
Objectives
To find out the level of Awareness of female genital cutting among postpartum mothers
To find out the knowledge of postpartum mothers about female genital cutting.
To find out the willingness of postpartum mothers to have genital cutting on their newborn females.
Presently, ethical approval has been obtained and questionnaires are being administered for the conduct of the study.
(E.) Pattern of Nuchal Translucency and Perinatal Outcome
Nuchal translucency (NT) has been found to be a useful prenatal diagnostic tool in screening for chromosomal abnormalities in the late first trimester of pregnancy. It was introduced into clinical practice in the 1990s, with most of the data derived from researches conducted and supervised by centres in European centres using mostly Caucasian population, while the derived values are used in all women irrespective of ethnic origin. In Nigeria, the nuchal translucency scan was introduced into clinical practice just more than a decade. The first-trimester scan was introduced initially with the aim of measuring the fetal crown-rump length to achieve accurate pregnancy dating, especially where the last menstrual period is unknown.
However, during the last few years, improvement in the resolution of ultrasonography machines has made it possible to describe the normal anatomy of the fetus and diagnose or suspect the presence of a wide range of fetal defects in the first trimester of pregnancy. The anatomical survey of a fetus in the first trimester is best done toward the end of the first trimester usually between the 11th to 14th week of gestation. An important component of the 11–13+6 week scan is measurement of fetal nuchal translucency thickness, which provides effective screening for chromosomal abnormalities, major defects of the heart and great arteries, and a wide range of skeletal dysplasia and genetic syndromes.
Nevertheless, controversies still exist on its use as a routine screening method especially in low risk population attributable to poor reproducibility of measurement, high false positive rates and poor screening sensitivity. Its major advantage however, is that it provides opportunity for an early pregnancy screening and decision about invasive procedures in high risk group. Where a termination of pregnancy is decided after evaluation, this is because it is to terminate pregnancies in the first trimester than afterwards. Other benefits includes major structural abnormalities can be ruled out at same scan session, confirmation of pregnancy, viability of pregnancy, number of fetus(es).
In view of the recent introduction of nuchal translucency in Nigeria there is paucity of data on this subject matter. Hence this research is conducted to determine the pattern and correlation between nuchal translucency measurements and pregnancy outcome in our locality.
This will be a prospective cohort study conducted at the Department of Obstetrics and Gynaecology of General Hospital, Ilorin, Kwara State. Participation will be voluntary and all involved women will complete a pre tested questionnaire with parameters like sociodemographic, obstetrics and medical history.
Inclusion Criteria
Consenting Pregnant women at 11–13+6 weeks gestation who present to antenatal booking clinic will be recruited
Exclusion criteria
Refusal to participate in the study
Pregnancies beyond 14 weeks gestational age and multiple pregnancies.
Following proper counseling and obtaining informed consent, the women will be asked if they are experiencing a full bladder or not. Those pregnant women who meet the conditions necessary to commence ultrasonography will be told to lie in supine position.
An ultrasound scan machine with 3.5–6.5 MHz curvilinear probe will be used for the conduct of this study. Proper training and calibration of the ultrasound machine use for nuchal translucency will be done by a Consultant radiologist to ensure that the results obtained are made to one decimal point and are reproducible. This ultrasound scan measurement will be done by a transabdominal route. Ultrasound scan will be done under the supervision of the Consultant Radiologist till proficiency is ensured.
