Hepatitis B vaccine birth dose coverage among hepatitis B-exposed and hepatitis B-unexposed infants: evidence from the Healthy Beginning Initiative program in Benue State, Nigeria.

Introduction: Nigeria offers universal hepatitis B birth-dose vaccine (HepB-BD) for the prevention and control of hepatitis B (HepB). While prior studies suggest low coverage of HepB-BD in Nigeria, there is a paucity of evidence on the association between the uptake of HepB-BD and maternal HepB status. This study aimed to determine HepB-BD coverage and the associated factors among infants of HepB-positive and -negative women in Nigeria. Methods: the study was a secondary analysis of data from the Healthy Beginning Initiative program conducted between June 2016 and October 2018 in Benue State, Nigeria. The analysis was restricted to data from a cohort of 6269 mothers who had HepB screening during pregnancy and completed the HepB infant immunization question in the post-delivery survey. The association between the coverage of HepB-BD and maternal HepB status, sociodemographic characteristics, and obstetric factors were determined using crude and adjusted relative risks. Results: about 10% of the women tested HepB positive. The coverage of HepB-BD was 64% (63.2% among infants of HepB-positive mothers and 63.8% among HepB-negative mothers). The likelihood of infants of HepB-positive mothers receiving HepB-BD was not significantly different from infants of HepB-negative mothers (aRR=0.97, 95%CI= 0.92-1.04). Among HepB-positive mothers, infants of mothers younger than 20 years (aRR=1.49, 95%CI=1.03-2.16) or those who received antenatal care (aRR=1.41, 95%CI=1.16-1.71) were more likely to receive HepB-BD, while mothers with no previous pregnancies (aRR=0.73, 95%CI=0.59-0.91) were less likely to receive HepB-BD. Among HepB-negative mothers, infants of less-educated mothers were less likely to receive HepB-BD (aRR=0.96, 95%CI=0.92-0.99), whereas infants of mothers who received antenatal care (aRR=1.23, 95%CI=1.16-1.31) or had an institutional delivery were more likely (aRR=1.29, 95%CI=1.23-1.36) to receive HepB-BD. Conclusion: our findings highlight the need to improve HepB-BD uptake, particularly among HepB-exposed infants who are at risk of perinatal transmission of HepB.

Physical Activity and Outdoor Leisure Time Physical Exercise: A Population Study of Correlates and Hindrances in a Resource-Constrained African Setting.

PURPOSE: The study evaluated the burden of physical inactivity, its correlates, and the self-reported hindrances to outdoor leisure-time physical exercises in Enugu Nigeria. It also evaluated the prevalence of leisure-time outdoor physical exercise and its correlates in Enugu Nigeria. PATIENT AND METHODS: This is a cross-sectional household survey involving 6628 individuals aged 20 to 60 years from 2848 households in Enugu Nigeria. Binary logistic regression and multinomial regression analyses were carried out as appropriate. Estimates were weighted to account for the actual population distribution of important sociodemographic variables and reported with the 95% confidence interval. RESULTS: The burden of physical inactivity was 32.68% (95% CI: 31.24-34.12%). Urban dwellers were less likely to be physically active than rural dwellers (AOR = 0.477; 95% CI = 0.410-0.555). For each year increase in age, the odds of being physically active decreases by a factor of 0.993 (AOR = 0.993; 95% CI= 0.988-0.998). Gender, income level and education did not predict physical inactivity. Physical inactivity significantly increases the odds of being obese by a factor of 1.428 (AOR: 1.428; 95% CI: 1.190-1.714). Only 6.45% (95% CI: 5.82%-7.09%) participants reported at least once a week outdoor leisure-time physical exercise. The major barriers include lack of time and lack of interest in outdoor leisure-time physical exercise. CONCLUSION: The burden of physical inactivity is high, while the level of outdoor physical exercise is low in Enugu, Nigeria. Urban dwelling and increasing age are risk factors for physical inactivity. Living in urban areas, being less than 40 years of age, having a university education, and a high personal income are factors that positively drive outdoor leisure-time physical exercises. Policies that will promote awareness of the health benefits of physical activity and outdoor physical exercise are needed if Nigeria is to achieve the global mandate of reducing physical inactivity by 10% in the year 2025.

Association between obesity and abnormal Papanicolau(Pap) smear cytology results in a resource-poor Nigerian setting.

BACKGROUND: Though obesity is associated with some malignancies, its association with cervical cancer is still inconclusive. This study was aimed at determining if there was an association between obesity and cervical epithelial cell abnormalities (CEA). METHODS: This was a cross-sectional comparative study of obese and non-obese women at the Cervical Cancer Screening Clinic, University of Nigeria Teaching Hospital (UNTH), Enugu between January, 2012 and June, 2013. The participants whose body mass index (BMI) were ≥ 30 kg/m2 were classified as obese (200 women) while those whose BMI were < 30 kg/m2 were classified as non-obese (200 women) and the two groups were consecutively recruited at the ratio of 1:1. Pap smear cytology, random blood sugar (RBS) and human immune-deficiency virus (HIV) screening was done for all the participants. Data was analyzed with SPSS version 20. Categorical variables were analyzed using McNemar's test and Chi-squared test. Logistic regression analysis was used to determine the influence of socio-demographic characteristics on cervical epithelial cell abnormalities. The level of significance was set at ≤0.05. RESULTS: Among the obese women, 152(76%) had negative for intra-epithelial lesion or malignancy (NILM) while 48(24%) had cervical epithelial cell abnormalities (CEA). Also 182(91%) non-obese women had NILM while the remaining 18(9%) had CEA. The prevalence of CEA among all the study participants was 16.5%. There was an association between obesity and CEA[OR (95%CI) = 1.353(1.013-1.812); P-value = 0.04].CEA were significantly more common among women who were 40 years and above and single/separated women as well as widows (P-value = < 0.05). CONCLUSION: There was an association between obesity and CEA. This underscores the need for a positive behavioural change among women in order to stem the tide of this public health problem.

Prevalence and sociodemographic determinants of adult obesity: a large representative household survey in a resource-constrained African setting with double burden of undernutrition and overnutrition.

BACKGROUND: The obesity epidemic has continued to spread across the globe involving even poor nations of the world. METHOD: Household population survey of adults aged 20-60 years. Multistage stratified cluster randomised sampling involving both urban and rural statewide representative population samples. Anthropometric measurements were taken using standard methods. Prevalences were weighted and multinomial regression analyses were done. RESULTS: A total of 6628 individuals from 2843 households were surveyed. The weighted overall prevalence for underweight was 9.1% (95% CI 8.1 to 10.1), 65.1% (95% CI 63.6 to 66.6) for normal weight, 19.0% (95% CI 17.8 to 20.3) for overweight and 6.8% (95% CI 6.0 to 7.5) for obese. Men were less likely to be overweight (adjusted OR (AOR) 0.79; 95% CI 0.68 to 0.92) and obese (AOR 0.24; 95% CI 0.19 to 0.31) than women. Urban residents were more likely to be overweight (AOR 1.42; 95% CI 1.18 to 1.71) and obese (AOR 2.09; 95% CI 1.58 to 2.76) than rural residents. Each additional 1-year increase in age increased the risk of overweight by 1.012 (AOR 1.012; 95% CI 1.005 to 1.018) and that of obesity by 1.03 (AOR 1.03; 95% CI 1.02 to 1.04). The low-income class was less likely to be overweight (AOR 0.694; 95% CI 0.507 to 0.951) and obese (AOR 0.44; 95% CI 0.28 to 0.67). CONCLUSION: The prevalence of obesity and overweight in Enugu Nigeria is high and fast approaching that of underweight. Women, urban dwellers, older adults and high-income earners are at higher risk for obesity and overweight. The study provides robust information for public health policies towards the prevention of obesity in Nigeria.

Association of Intrauterine Device (IUD) and Cervical Neoplasia - A Study in a Poor Nigerian Population.

INTRODUCTION: Intrauterine Device (IUD) is a contraceptive method used by women of reproductive age group. However, there are conflicting reports on the association between IUD and cervical neoplasia. These controversies may further hamper the poor uptake of modern contraception in Nigeria. AIM: This study was therefore aimed at evaluating the association between IUD and cervical neoplasia. MATERIALS AND METHODS: This was a case control study in which Pap smear results of 156 participants on IUD were compared with those of 156 non-users of modern contraception. The participants who were found to have abnormal cervical smear cytology results were further subjected to colposcopy. Biopsy specimens for histology were collected from the participants with obvious cervical lesions or those with suspicious lesions on colposcopy. The results were analysed with descriptive and inferential statistics at 95% level of confidence. RESULTS: Seven (4.5%) and 2(1.3%) of participants using IUD had Cervical Intraepithelial Neoplasia (CIN) 1 and CIN 2 respectively. Also, 5(3.2%) and 1(0.6%) of non-users of modern contraception had CIN 1 and CIN 2 respectively. The prevalence of cervical neoplasia among all the participants was 4.8%. Although, the proportion of women who had CIN was more among participants using IUD than non-users of modern contraception, the difference was not statistically significant. CONCLUSION: There was no significant association between IUD and cervical neoplasia in this study.

Is there any association between hormonal contraceptives and cervical neoplasia in a poor Nigerian setting?

BACKGROUND: The association between hormonal contraception and cervical cancer is controversial. These controversies may hamper the uptake of hormonal contraceptives. OBJECTIVE: To determine the association between hormonal contraceptives and cervical neoplasia. MATERIALS AND METHODS: This was a case-control study in which Pap-smear results of 156 participants on hormonal contraceptives were compared with those of 156 participants on no form of modern contraception. Modern contraception is defined as the use of such contraceptives as condoms, pills, injectables, intrauterine devices, implants, and female or male sterilization. Those found to have abnormal cervical smear cytology results were subjected further to colposcopy. Biopsy specimens for histology were collected from the participants with obvious cervical lesions or those with suspicious lesions on colposcopy. The results were analyzed with descriptive and inferential statistics at a 95% level of confidence. RESULTS: A total of 71 (45.5%), 60 (38.5%), and 25 (16.0%) of the participants on hormonal contraceptives were using oral contraceptives, injectable contraceptives, and implants, respectively. Cervical neoplasia was significantly more common among participants who were ≥35 years old (6% versus 1%, P<0.0001), rural dwellers (6% versus 3.5%, P<0.0001), unmarried (7.6% versus 3.5%, P<0.0001), unemployed (6.8% versus 3.5%, P<0.0001), less educated (6% versus 3.8%, P<0.0001), and had high parity (6.8% versus 3.6%, P<0.0001). There was no statistical significant difference in cervical neoplasia between the two groups of participants (7 [4.5%] versus 6 [3.8%], P=1.0). CONCLUSION: There was no association between hormonal contraceptives and cervical neoplasia in this study.

Oral versus vaginal misoprostol for induction of labor in Enugu, Nigeria: a randomized controlled trial.

OBJECTIVE: The study aimed at comparing the effectiveness and maternal satisfaction of oral misoprostol with vaginal misoprostol for induction of labor at term. MATERIALS AND METHODS: A randomized controlled trial of 140 term pregnant women at the University of Nigeria Teaching Hospital Enugu, Nigeria, was conducted from April 2011 to May 2012. The women were equally randomized into two groups (A and B) to receive oral and vaginal misoprostol, respectively. RESULTS: The vaginal route reduced the mean induction-vaginal delivery interval by four-and-half hours (20.7 ± 12.1 vs. 16.2 ± 10.4; mean difference: 4.50, 95% CI 0.63-0.82; p = 0.02). Furthermore, the mean dose of misoprostol required to achieve induction of labor and the mean duration of oxytocin augmentation when indicated were significantly less in the vaginal group than in the oral group (2.5 ± 1.3 vs. 2.0 ± 1.1; mean difference: 0.50, 95% CI 0.10-0.90; p = 0.02 and 4.6 ± 3.2 vs. 3.4 ± 3.1; mean difference: 1.20, 95% CI 0.15-0.23; p = 0.03 respectively). However, neonatal complications and maternal satisfaction were similar between the two groups. CONCLUSION: Both routes of administration are effective in the induction of labor at term and have comparable maternal satisfaction. However, the vaginal route has the added advantage of shorter induction-delivery interval among others, and thus should be highly considered when induction of labor is indicated at term.

Why southeastern Nigerian women who are aware of cervical cancer screening do not go for cervical cancer screening.

OBJECTIVE: This study aimed to evaluate reasons behind nonuptake of cervical cancer screening by women who are aware of cervical cancer screening in southeast Nigeria. METHOD: Women attending gynecologic clinics of 3 health institutions in Enugu, Nigeria, were interviewed by means of a questionnaire to determine those who were aware of cervical cancer screening. The biodemographic characteristics and level of knowledge of cervical cancer screening of women who underwent a previous screen were compared with those of women who did not undergo a previous screen. Reasons for nonuptake of cervical cancer screening as well as potential reasons for undertaking cervical cancer screening were also extracted. RESULTS: A total of 3712 women were interviewed. Of these respondents, 2048 (55.2%) were aware of cervical cancer screening.Only 19.0% of those who were aware of cervical cancer screening underwent a previous screen. Level of knowledge of cervical cancer prevention, university education, and age had a significant impact on the uptake of cervical cancer screening. Poor health-seeking behavior and fear of violation of privacy are the major reasons for nonuptake of cervical cancer screening. Potential reasons for uptake of cervical cancer screening include development of symptoms, adequate educative information, and physician's recommendation. CONCLUSIONS: Women in southern Nigeria do not go for cervical cancer screening because of poor understanding of cervical cancer prevention, feeling of violation of the privacy of their genitals, and poor health-seeking behavior. There is a need to modify current policy approaches to cervical cancer prevention in Nigeria. Policies that will address the privacy violation fears and poor health-seeking behavior of the Nigerian woman as well improve the level of educative information on cervical cancer prevention need to be evolved.

Women's opinions and experiences with induction of labor and cesarean delivery on request in south eastern Nigeria.

OBJECTIVE: To assess the opinions and experiences of women regarding induction of labor and cesarean delivery on request in south eastern Nigeria. METHOD: Women were interviewed using questionnaires on their awareness of their right to request labor induction and/or a cesarean delivery, and of their experience and opinion of the procedures. RESULTS: Of the 15.1% of the respondents who knew they could request a cesarean delivery, 2.4% had requested one; and of the 56.3% who knew they could request labor induction, 6.9% had requested one. Only 5.3% and 11.3% of the respondents who would chose the former or the latter procedure, respectively, said that they would insist on receiving it. Fear of their physicians' negative attitude regarding the procedures, and/or abandonment of care, ranked highest among their reasons for not insisting. CONCLUSION: In south eastern Nigeria few women are aware of their right to a cesarean delivery on request and the rate of refusal to perform such deliveries is high among physicians; more women are aware of their right to receive induction of labor on request and the acceptance rate is higher among physicians; and most women are unwilling to insist that their physician respect their choice.

Implications of incorrect determination of fetal sex by ultrasound.

OBJECTIVE: To assess the experiences of women following incorrect determination of fetal sex by ultrasound. METHOD: A 3-year prospective cohort study of 102 women with discordance between fetal sex determined by ultrasound scan and birth sex. Participants were interviewed using 2 structured pretested questionnaires. The first questionnaire was undertaken within 24 h of delivery. The women were followed up with a second questionnaire 6-9 months later. In-depth interviews were also carried out at this time. RESULTS: Women who had received an incorrect determination of fetal sex by ultrasound experienced marital conflicts, domestic violence, negative perceptions of ultrasound, and a desire for reversal of tubal ligation. CONCLUSION: Incorrect determination of fetal sex by ultrasound has implications that can affect the mental and psychological health of the mother and the upbringing of the newborn.
