Abstract: Background: Neonatal tetanus (NNT) is a deadly vaccine preventable disease and one of the most underreported diseases in the developing countries seen in the newborn within the first 28 days of life. NNT remains one of the leading causes of deaths among neonates in the developing countries with about 130,000 neonatal deaths recorded in 2004. Despite the global success recorded in the NNT elimination strategy, Nigeria remains among the 25 remaining countries that record NNT cases. Study Design: Retrospective study Methods: This quantitative cross-sectional study involved mothers who gave birth to children with NNT within their first 28 days of life. The study used secondary data collected between January 2008 and December 2013 from northeast region of Nigeria. Results: The results revealed that 58% had male children (n =182) and the remaining 42% had female children (n = 130). The predominance of the male neonates could partly be as a result of the socio-cultural preference given to the male child in Nigerian. Conclusion: There is the need for parents to promptly seek urgent medical attention for all suspected NNT cases irrespective of the gender of the child to reduce neonatal mortality rates.

1. Introduction

Although efforts put in place by international agencies and government of countries towards improving the health of children across the globe has yielded positive results, arguably this is more in the developed countries than the developing countries. With an estimated 10 million annual deaths of children under the age of 5 years across the globe, it is sad to note that 4 million of these deaths occur within the first 28 days of life of these children, and in the developing countries1,2,3,16,17,18. Thus, the burden is more on the developing countries due to the enormous challenges with high infant and neonatal death rates.

Studies show that Neonatal tetanus (NNT) is still one of the most underreported deadly vaccine preventable diseases that is commonly seen in the developing countries. In spite the increased commitment from governments of countries that have NNT, it is estimated that only 5% of cases reports to the heath services especially within the under-developed countries4,5,6,16,17,18.

As a result of this unacceptable high neonatal mortality rates, during the World Health Assembly of 1989 and the World Summit for Children in 1990, that the WHO, UNICEF and other partner agencies developed a strategic NNT elimination framework with the initial target date in 19954,5,16,17,18. The NNT elimination framework targets less than 1 NNT case per 1,000 live births per annum in every district of every country across the globe. The components of the framework include strengthening of routine immunization of all pregnant women with the tetanus toxoid (TT), immunization of women with 3 doses of tetanus toxoid vaccine during their childbearing age more especially those living in high-risk areas, hygienic delivery of the newborn, and improved NNT surveillance4,5,6,19. As a result of failure of several countries to meet with the deadline, the target date for the global NNT elimination was revised to 20155,6,16,17,18.

In spite the fact that this strategic plan has yielded remarkable improvement in NNT across the globe evidenced by a 93% reduction in cases, statistics shows that as at December 2013 there are still 25 countries that fail short of meeting with the NNT elimination goals. Notably, Nigeria, with all its vast human and capital resources is among the 25 remaining countries with unacceptably high prevalence of NNT5,16,17,18.

The study was conducted in the northeast region of Nigeria; this sub-region comprises of six provinces: Adamawa, Bauchi, Borno, Gombe, Taraba, and Yobe. As shown in the Demographic and Health Survey of 2008, the northeast region has an interesting health statistics: total fertility rate of 7.2 (national 5.7), women age 15-19 who are mothers 39% (national 23%), women who gave birth in the last 5 years and received antenatal care from a skilled provider 43% (national 58%), Births assisted by a skilled provider 16% (national 39%), Births delivered in a health facility 13% (national 35%), Children 12–23 months fully immunized 8% (national 23%), Children 12–23 months with no immunizations 33 (national 29%), Literate women age 15–49/men age 15–49, stands at 23/54 (national 54/77%), and those with no education women age 15–49/men age 15–49, stands at 68/45 (national 36/19%)8.

2. Methodology

The study is a cross-sectional quantitative study and retrospective in nature. The secondary data used is the NNT dataset that was collected from 2008 – 2013. The sample size of the participants was 312 mothers who gave birth to NNT babies. As compared with the southern region of Nigeria, the northeast region is less densely populated. With Islam and Christianity as the two dominant religions, the rural dwellers in the region are mostly farmers and often with large-scale production of crops and livestock. In comparison with other regions in Nigeria, the northeast region has poorer economic indices and worse health outcomes7,8.

The selection criteria for is that eligible participants are mothers of child bearing age from the six provinces who gave birth to newborn children that died within the first 28 days of life as a result of symptoms inline with the standard NNT case definition or as diagnosed by a clinician as NNT.

This research work obtained ethical approval for the use of the NNT dataset from the zonal office of the National Primary Health Care Development Agency. The NNT data was collected from eligible participants in the northeast region using a standard tool. Informed of consent of the participants was obtained from the local authorities and the husbands of these women prior administering the questionnaire. The participants were well informed in the local language that they understood on the purpose of administering the questionnaire. The information obtained was securely kept in the official database, and restricting data access except to authorize persons.

The instrument used for collecting data from the respondents has on its various columns the following: the first column for capturing demographic information of the NNT child, as well as that of the parents. Other columns are tailored to obtain information on the mother’s vaccination history, birth of an infant, initial clinical history, treatment, action taken in the form of response, and final classification of the case. To ensure that the outcome is valid and generalizable, quality of the items was sought with content validity. The content of the instrument clearly measures what it was expected to measure; thus validity and reliability of the measurement instrument was well tested9,10.

3. Results

The authors used Statistical Package for the Social Sciences (SPSS) version 22 to code and tabulate the scores collected from the survey. The summary of values, where applicable, includes the mean, central tendency, variance, and standard deviation. Both inferential and descriptive statistics were used to draw conclusions from the sample.

As shown in Table 1, the data collected from a sample of 312 mothers from the northeast region of Nigeria revealed that 58% (182/312) of the participants had male children (n =182) and the remaining 42% (130/312) had female children (n = 130). Furthermore, 8% (25/312) were from Adamawa province (n = 25), 20% (62/312) were from Bauchi province (n = 62), 28% (86/312) were from Borno (n = 86), 17% (53/312) were from Gombe province (n = 53), 18% (55/312) were from Taraba province (n = 55), and the remaining 10% (31/312) were from Yobe province (n = 31). Additionally, Table 2 shows that highest number of neonates who had NNT [26% (80/306)] was in 2010, whereas fewer neonates had NNT [9% (27/306)] in 2013.

From the sample of 312 participants, two said they had a child without NNT (n = 2), and five did not respond to NNT status (nmissing = 5). The two NNT babies were both males with different backgrounds. That is, case #157 was born in 2008 in the Borno province and the mother did not receive antenatal care, nor was she attended by a TBA; whereas, case #260 was born in 2009 in the Taraba province, had received antenatal care, and had the umbilical cord treated. Demographic statistics of the two participants with non-NNT babies and those that did not respond to NNT status were displayed in Table 3.

4. Discussion

The authors used Statistical Package for the Social Sciences (SPSS) 22 to analyze the data. Descriptive statistics and exploratory analysis for the differences in frequency between the variables was conducted.

The result of this study shows that there were more male neonates with neonatal tetanus as compared with female neonates. The predominance of the male neonates among reported NNT cases is in agreement with other previous studies11-15. While outright reason for the dominance of male neonates with NNT in this study could not be ascertained, the disparity between the reported cases could partly be as a result of the socio-cultural preference given to the male child in the Nigerian community, which makes parents seek medical attention for the male child promptly as against the female child15.

In a related study in India, it was observed that the excess female neonatal mortality recorded is as a result of sex-selective prenatal care in maternal tetanus vaccination. The study added that mothers attend ANCs to get vaccinated with the TT more often when the baby in-utero is a boy as compared to a girl20.

Although significant achievement has been made in the current global fight against maternal and neonatal tetanus (MNT), much needs to be done in the developing countries such as Nigeria. Considering the deadly nature of NNT even in the best of centres, there is need for policy makers and stakeholders to increase awareness of the parents about the disease and educate them on the need to promptly seek urgent medical attention for all suspected NNT irrespective of the gender of the child. This would help meet up with the MDG goals to improve the health indicators by reducing mortality rates in the under fives.
