RESUMO
Background: Unintended pregnancy is a global public health issue with significant adverse effects which include health and economic consequences. Globally, there were 121 million unintended pregnancies annually between 2015 and 2019 among women of reproductive age between 15 and 49 mainly due to the non-uptake of modern contraceptives, harmful norms, stigma and lack of sexual and reproductive health care and information. Methods: We extracted information from the Nigeria Demographic Health Survey conducted in 2008, 2013, and 2018 to assess the trends and factors associated with unintended pregnancies among women of reproductive-aged 15-49. The descriptive summaries were presented using percentages and binomial logistic regressions for the inferential analysis. All analyses were computed using Stata 15.0 at a 5% level of significance and accounted for the complex survey nature as well as the population size. Results: The study included a total of 63,040 women of reproductive age. The prevalence of unintended pregnancy was highest among adolescents aged 15-19 years (15.1%, 95% CI: 13.9-16.5) and decreased with increasing age. The pooled adjusted model revealed that women had 11% lower odds of reporting unintended pregnancies in 2013 compared to 2008. Adolescent girls (aOR 2.48; 95%CI: 2.14-2.89) and young adults (aOR 1.86; 95%CI: 1.69-2.04) have higher odds of reporting unintended pregnancies compared to older women. Also, unmarried women had 9.8 times higher odds of reporting unintended pregnancies compared to ever-married women. Conclusions: The findings from this study highlight the need for further family planning educational programs and initiatives that support the uptake of effective contraceptive methods to reduce the likelihood of unintended pregnancy and improve women's sexual and reproductive health while considering regional variations within the country to ensure tailored interventions that address specific needs within each region.
RESUMO
BACKGROUND: Iodine deficiency is the most common cause of thyroid disease, and in its severe form can result in cretinism; the impairment of the brain development of a child. Pregnant and breastfeeding women's daily iodine requirement is elevated due to physiological changes in iodine metabolism, requiring up to double the iodine intake of other women. Although Nigeria was the first African country to be declared iodine sufficient in 2007, recent evidence has shown that only about seven in ten households consume salt with adequate iodine content (≥ 15 ppm), with variation across states. The study aimed to assess the Individual- and household-, community- and state-level factors associated with inadequate iodised salt consumption among pregnant women and breastfeeding mothers in Nigeria. METHODS: This study utilised the Multiple Indicator Cluster Survey to assess factors associated with inadequate iodised salt consumption among 4911 pregnant women and breastfeeding mothers in Nigeria. The descriptive analysis was presented using frequencies and percentages. The prevalence of adequate and inadequate iodised salt consumption with their 95% confidence interval were computed. Several multi-level mixed effect log-binomial logistic regressions were used to explore the factors associated with inadequate iodised salt consumption. The Loglikelihood, Akaike Information Criterion and Bayesian Information Criterion were used to assess the goodness of fit of the models. All analyses were adjusted for the complex survey design and analysed using Stata 15.0 at p < 0.05. RESULTS: The prevalence of inadequate iodised salt consumption among pregnant and breastfeeding mothers was 35.2% (95% CI: 33.1-37.5). Inadequate consumption of iodised salt was highest among pregnant and breastfeeding women aged 45-49 years (48.2%; 95%CI: 37.8-58.8), as well as those with non-formal education (52.7%; 95%CI: 47.7-57.6) and no education (34.6%; 95%CI: 31.3-38.1). Our findings revealed that pregnant and breastfeeding women living in the poorer, middle, richer and richest quintiles were 32%, 47%, 35% and 62% less likely to consume salt with inadequate iodine compared to those in the poorest households. Those with non-formal education were 1.8 times (95%CI: 1.36-2.42) more likely to consume salt with deficient iodine than those without education. Pregnant and breastfeeding mothers residing in moderately and most deprived communities were 3.5 (95%CI: 2.57-4.73) and 4.7 times (95%CI: 3.38-6.55) more likely to consume salt with inadequate iodine than those from least deprived communities. Women in the Northwestern region and those from the Southwestern region were 4.0 and 3.5 times, respectively, more likely to consume salt with inadequate iodine compared to pregnant and breastfeeding women residing in the North-Central region. CONCLUSIONS: The study has shown that inadequate consumption of iodised salt dominates among older pregnant and breastfeeding women. Also, women with non-formal education have higher prospects of consuming salt with lesser iodine. There is a need to enhance women's economic opportunities and empowerment as well as sensitisation on their nutritional requirements during pregnancy and breastfeeding. Both formal and non-formal educational initiatives on nutrition are extremely important and should be prioritised by the Nigerian government in its efforts to encourage the consumption of iodised salt among pregnant and lactating mothers. Additionally, health promotion interventions that seek to advocate iodised salt intake must be prioritised by the actors in the health sector.

Background: The prevalence of HIV among young people aged 15-19 years in Nigeria is estimated as 3.5%, the highest among West and Central African countries. Comprehensive knowledge of HIV is associated with increased awareness of preventive interventions and a reduction in the spread of HIV. Therefore, this article seeks to assess and determine the associated factors of comprehensive HIV knowledge among youths in Nigeria. Methods: The study used the 2018 Nigerian Demographic Health Survey, a cross-sectional survey that employed a two-stage cluster sampling method. Comprehensive knowledge of HIV was assessed based on five questions. The data were analysed separately for men and women aged 15-24 years. A multivariable log-binomial regression model was used to determine factors associated with comprehensive HIV knowledge. All analysis was performed using Stata 15.0 and adjusted for weighting, clustering and stratification. Results: A total of 15,267 women and 4019 men aged 15-24 years were included in this study. The prevalence of comprehensive knowledge of HIV was higher among women than among men (42.6% versus 33.7%; p < 0.001) and lower among younger ages 15-17 years compared with other ages. The findings revealed that age, ethnicity, wealth, education and exposure to mass media were statistically significant factors associated with comprehensive knowledge of HIV. In addition, religion, place of residence, phone ownership, internet use, currently working and having initiated sex were significant factors among women and modern contraceptive use among men. Conclusion: Key findings from this study imply that public health programmes in Nigeria should focus on providing information on HIV/AIDS using different approaches, including comprehensive sex education as well as health promotion and education strategies in the formal and informal sectors. Because media exposure is a common and cost-effective way of public health promotion and education in modern times, emphasis could also be placed on using this channel to reach the target population.
RESUMO
Background: Teen pregnancy and childbearing are common in Nigeria, and understanding the complexities, such as sociodemographics and economic factors including sexual and reproductive health knowledge and awareness among adolescents over time can trigger innovative approaches and interventions. This study intends to capture the patterns and associated factors of teen motherhood among sexually active adolescents (15-19 years) between 2008 and 2018. Methods: The study data was extracted from 2008, 2013, and 2018 Nigeria Demographic and Health Surveys. Descriptive analysis was presented using frequencies and percentages; multivariable analysis was conducted using log-binomial logistic regression at a p-value <0.05. All analyses were performed using Stata 15.0, weighted and adjusted for the complex survey design and population size. Results: The prevalence of teen motherhood increased between the three successive survey waves (50.9% vs. 52.4% vs. 55.2%) from 2008, 2013, and 2018. Although, the pooled adjusted analysis revealed no significant change over the 10-year period. Knowledge of modern contraceptive methods, primary education, non-Catholic Christians, residing in the South-South region, and those currently or formerly married were associated with increased risk of teen motherhood. There was an inverse relationship between teen motherhood and wealth status; lower wealth status was associated with high adolescent pregnancy and childbearing. Conclusion: This study revealed an increase in the proportion of teen pregnancy and childbearing in Nigeria. Notably, there exist variations across age groups, geographic location, educational level, religious belief, marital and economic status. Interventions that ensure comprehensive sexuality education, girl child education, and economic empowerment especially for school dropouts are advocated to reduce teen motherhood.
RESUMO
INTRODUCTION: Anaemia remains a major public health concern, particularly, in sub-Saharan Africa (SSA), where it is one of the causes of maternal death. The most common cause of maternal anaemia is iron deficiency or malnutrition. This study examined the prevalence of and risk factors for anaemia among women that participated in the Nigerian Demographic Health Survey. METHOD: We used data of 14,454 women that participated in the 2018 Nigeria Demographic and Health Survey (NDHS). We extracted information such as demographic, social and housing, dietary characteristics and haemoglobin concentration. The descriptive statistic results, prevalence and 95% confidence interval (CIs) of anaemia with the selected respondents background characteristics were presented. The Poisson regression model with robust variance was used to assess the risk of anaemia among women of reproductive age. All analyses were weighted and adjusted for the complex survey design. Statistical significance was interpreted at p value < 0.05. RESULTS: Maternal status, body mass index, education, residence, religion, ethnicity, region and type of cooking fuel were all important determinants of anaemia. The prevalence of anaemia was high among pregnant women (61.8%; 95% CI: 58.5-65.0), adolescents (60.4%; 95% CI: 58.1-62.6), underweight women (62.6%; 95% CI: 59.5-65.5), women who had no formal education (64.1%; 95% CI: 62.2-66.0) and those who belonged to the poorest wealth quintile (65.8%; 95% CI: 63.1-68.4). Similarly, anaemia was high among women residing in rural areas (61.5%; 95% CI: 60.0-63.0), Muslims (59.9%; 95% CI: 58.1-61.6) and women with six or more children (62.1%; 95% CI: 60.0-64.1). The risk of anaemia were 2% less likely among women who took minimum adequate diet compared to those who do not. CONCLUSION: To date, this is the largest data on maternal anaemia in Nigeria. The study highlighted the high burden of maternal anaemia in the country and different risk factors (medical and social) that are associated with this medical condition among women of reproductive age. We recommend future longitudinal studies to test hypothesis in order to assess whether there is any causal relationship between identified risk factors and anaemia in this group of women.

BACKGROUND: Female Genital Mutilation (FGM) is believed to have a negative effect on sexual and reproductive health but the evidence from nationally representative sample in high-burdened countries like Nigeria is scarce. This study explored the association between FGM and sexual behaviour in a nationally representative sample of Nigerian women. METHODS: A secondary data analysis was conducted using the Nigeria Demographic Health Survey conducted in 2013 and 2018 among women aged 15-49 years. The descriptive summaries of respondent characteristics by marital status were presented using frequencies and percentages. The proportion and 95% Confidence Interval (CI) of circumcision by sexual behaviour characteristics were computed. A multivariable log-binomial logistic regression was used to determine the association between sexual behaviour and female circumcision while adjusting for other covariates. All analyses were performed using Stata 15.1 (StataCorp, College Station, TX, USA) at the 0.05 level of significance. RESULTS: The proportion of circumcised women was 38.6% among those who were ever-married and 32.4% among those unmarried. There were no statistically significant relationship between circumcision status and sexual behaviour among women who were unmarried. However, circumcised women who were ever married had 18% higher risk of having contracted sexually transmitted disease in the last 12 months preceeding the survey and 10% higher risk of engaging in pre-marital sex compared to ever married women who were uncircumcised after adjusting for other covariates. However, the risk of having multiple sexual partners in the last 12 month among uncircumcised ever married women was lower (aRR = 0.80; 95% CI: 0.66-0.97) in the adjusted model. CONCLUSION: Circumcision is not associated with positive sexual behavioural outcomes including delay in sexual debut, virginity and marital fidelity, although there exists some perception behind increasing FGM in Nigeria including prevention of premarital sex and ensuring marital fidelity. While we strongly discourage FGM in all its form, we assert the need for alternative health promoting community measures to address these inherent sexual perceptions toward eliminating FGM and improving sexual and reproductive health across population groups.

Despite a total prohibition on the practice of female genital mutilation (FGM), young girls continue to be victims in some African countries. There is a paucity of data on the effect of FGM practice in two generations in Africa. This study assessed the current practice of daughters' FGM among women living in 14 FGM-prone countries in Africa as a proxy to assess the future burden of FGM in the continent. We used Demographic and Health Surveys data collected between 2010 and 2018 from 14 African countries. We analyzed information on 93,063 women-daughter pair (Level 1) from 8,396 communities (Level 2) from the 14 countries (Level 3). We fitted hierarchical multivariable binomial logistic regression models using the MLWin 3.03 module in Stata version 16 at p<0.05. The overall prevalence of FGM among mothers and their daughters was 60.0% and 21.7%, respectively, corresponding to 63.8% reduction in the mother-daughter ratio of FGM. The prevalence of FGM among daughters in Togo and Tanzania were less than one per cent, 48.6% in Guinea, with the highest prevalence of 78.3% found in Mali. The percentage reduction in mother-daughter FGM ratio was highest in Tanzania (96.7%) and Togo (94.2%), compared with 10.0% in Niger, 15.0% in Nigeria and 15.9% in Mali. Prevalence of daughters' FGM among women with and without FGM was 34.0% and 3.1% respectively. The risk of mothers having FGM for their daughters was significantly associated with maternal age, educational status, religion, household wealth quintiles, place of residence, community unemployment and community poverty. The country and community where the women lived explained about 57% and 42% of the total variation in FGM procurement for daughters. Procurement of FGM for the daughters of the present generation of mothers in Africa is common, mainly, among those from low social, poorer, rural and less educated women. We advocate for more context-specific studies to fully assess the role of each of the identified risk factors and design sustainable intervention towards the elimination of FGM in Africa.

BACKGROUND: In November 2016, the WHO four-visit focused antenatal care (FANC) model adopted in sub-Saharan Africa (SSA) was reverted to eight contacts or more as a response to reducing the global perinatal and maternal deaths and in achieving the sustainable development goal (SDG) 3. Women's empowerment, which connote the social standing, position and the ability of women to make life decisions and choices has been associated with the maternal health seeking behaviour and outcomes. This study examined the association between women's empowerment and the WHO ANC model of eight visits or more, and early first antenatal visit among pregnant women. In addition, we explored the association between women's empowerment and the WHO FANC model to allow for comparison for countries that have not adopted the recent WHO ANC model. METHODS: The most recent (2018) Demographic and Health Survey (DHS) datasets conducted in SSA were used for analyses. We used all available indicators of women's empowerment captured in the DHS. The 30 variables on women's empowerment were classified into eight components using exploratory factor analysis. We fitted separate ordinal logistic regression to assess association between antenatal care utilization (number of visits and time of first antenatal visit) and women empowerment factors while adjusting for other covariates. Analysis was performed with STATA 15.0 and adjusted for complex survey design, p-value< 0.05 were used for interpretation of results. RESULTS: The proportion of women who attended eight or more ANC visits were 1.4, 2.7 and 3.5% in Zambia, Guinea and Mali, respectively. Zambia had the lowest prevalence of 8 or more ANC visits also had the highest prevalence of at least 4 visits (63.8%) and early first ANC visit (38.2%), while Nigeria with the highest prevalence of women with at least 8 visits (17.7%) had the lowest prevalence (17.6%) of women that attended ANC visit in their first trimester. Women's empowerment was associated with more ANC visits and attending first ANC visit in the first trimester. However, these association with the women empowerment components varied significantly across the four SSA countries. CONCLUSION: This study highlights the significant impact of women's empowerment as a key factor for improving maternal health outcomes in SSA. It is imperative that government and development partners invest more on empowerment of women as part of strategic intervention to improve maternal health outcomes.

BACKGROUND: About 31 million children in sub-Saharan Africa (SSA) suffer from immunisation preventable diseases yearly and more than half a million children die because of lack of access to immunisation. Immunisation coverage has stagnated at 72% in SSA over the past 6 years. Due to evidence that full immunisation of children may be determined by place of residence, this study aimed at investigating the rural-urban differential in full childhood immunisation in SSA. METHODS: The data used for this study consisted of 26 241 children pooled from 23 Demographic and Health Surveys conducted between 2010 and 2018 in SSA. We performed a Poisson regression analysis with robust Standard Errors (SEs) to determine the factors associated with full immunisation status for rural and urban children. Likewise, a multivariate decomposition analysis for non-linear response model was used to examine the contribution of the covariates to the observed rural and urban differential in full childhood immunisation. All analyses were performed using Stata software V.15.0 and associations with a p<0.05 were considered statistically significant. RESULTS: More than half of children in urban settings were fully immunised (52.8%) while 59.3% of rural residents were not fully immunised. In all, 76.5% of rural-urban variation in full immunisation was attributable to differences in child and maternal characteristics. Household wealth was an important component contributing to the rural-urban gap. Specifically, richest wealth status substantially accounted for immunisation disparity (35.7%). First and sixth birth orders contributed 7.3% and 14.9%, respectively, towards the disparity while 7.9% of the disparity was attributable to distance to health facility. CONCLUSION: This study has emphasised the rural-urban disparity in childhood immunisation, with children in the urban settings more likely to complete immunisation. Subregional, national and community-level interventions to obviate this disparity should target children in rural settings, those from poor households and women who have difficulties in accessing healthcare facilities due to distance.

INTRODUCTION: Involuntary leakage of urine and or stool per vaginam (vaginal fistula) after childbirth remains a public health challenge in Africa and South East Asia. To the best of our knowledge, there is no previous national data that examined the awareness of vaginal fistula among women in Nigeria. AIM: To determine the prevalence of awareness of urinary/faecal incontinence due to vaginal fistula, and the associated risk factors among women with no previous experience of incontinence. METHODS: We used a cross-sectional study, the 2018 Nigerian Demographic Health Survey, to analyse awareness of vaginal fistula among women with no previous leakage of urine or stool. The primary outcome was childbirth experience, and other variables were demographics, access to information and reproductive or sexual history. The descriptive, univariate and multivariable models were presented. RESULTS: Of 26 585 women interviewed, 50 (0.2%) who had experienced fistula were excluded from the risk factor analysis. The mean age of women with childbirth experience was 32.8±8.6 years, while that of women without childbirth experience was 20.3±6.2 years. The prevalence of vaginal fistula awareness was 52.0%. Factors associated with the awareness include the following: childbirth experience (adjusted OR (AOR)=1.14; 95% CI, 1.01 to 1.30); age of 20-24 years (AOR=1.36; 95% CI, 1.18 to 1.56) and older; currently working (AOR=1.35; 95% CI, 1.22 to 1.49) and ownership of a mobile phone (AOR=1.16; 95% CI, 1.05 to 1.27). Other associated factors include the following: having at least secondary education; wealth quintiles, ethnicity, regional location, religion, access to radio, newspaper and internet; age up to 17 years at first sex; history of previous termination of pregnancy and use of contraception. CONCLUSION: A significant number of young women with no childbirth experience had low level of awareness. We recommend vaginal fistula awareness programmes that will target women at risk of vaginal fistula and the inclusion of other useful questions to improve the quality of information in future surveys.

BACKGROUND: Use of insecticide-treated net (ITN) has been identified by the World Health Organization as an effective approach for malaria prevention. The government of Uganda has instituted measures to enhance ITN supply over the past decade, however, the country ranks third towards the global malaria burden. As a result, this study investigated how individual, community and region level factors affect ITN use among women of reproductive age in Uganda. METHODS: The 2018-2019 Malaria Indicator Survey of Uganda involving 7798 women aged 15-49 was utilized. The descriptive summaries of ITN use were analysed by individual, community and region level factors. Based on the hierarchical nature of the data, four distinct binomial multilevel logistic regression models were fitted using the MLwiN 3.05 module in Stata. The parameters were estimated using the Markov Chain Monte Carlo (MCMC) estimation procedure and Bayesian Deviance Information Criterion was used to identify the model with a better fit. RESULTS: The proportion of women who use ITN was 78.2% (n = 6097). Poor household wealth status [aOR = 1.66, Crl = 1.55-1.80], knowing that sleeping under ITN prevents malaria [aOR = 1.11, Crl = 1.05-1.24] and that destroying mosquito breeding sites can prevent malaria [aOR = 1.85, Crl = 1.75-1.98] were associated with higher odds of ITN use. ITN use attributable to regional and community level random effects was 39.1% and 45.2%, respectively. CONCLUSION: The study has illustrated that ITN policies and interventions in Uganda need to be sensitive to community and region level factors that affect usage. Also, strategies to enhance women's knowledge on malaria prevention is indispensable in improving ITN use.

Female Genital Mutilation or Cutting (FGM) and its medicalisation remain a challenge in sub-Sahara African (SSA). Early identification of at-risk women might help in instituting focused counselling against FGM medicalisation. We hypothesised that the risk of medicalised FGM by girls/women is associated with socioeconomic status (SES) their household belongs. We used 2010-2019 Demographic and Health surveys data from 13 countries in SSA. We analysed information on 214,707 women (Level 1) nested within 7299 neighbourhoods (Level 2) from the 13 countries (Level 3). We fitted 5 multivariable binomial multilevel logistic regression models using the MLWin 3.03 module in Stata. The estimation algorithms adopted was the first order marginal quasi-likelihood linearisation using the iterative generalised least squares. The odds of FGM medicalisation increased with the wealth status of the household of the woman, with 29%, 45%- and 75%-times higher odds in the middle, richer and richest household wealth quintiles, respectively than those from the poorest households (p < 0.05). The more educated a woman and the better a woman's community SES was, the higher her odds of reporting medicalisation of FGM. Rural community was associated with higher odds of medicalised FGM than urban settings. Medicalised FGM is common among women from a high socioeconomic, educational background and rural settings of SSA. We recommend a culturally sensitive policy that will discourage perpetuation of FGM, particularly by healthcare providers. Future studies should focus on identifying drivers of FGM among the high social class families in the society in SSA.
RESUMO
PURPOSE: Poor knowledge regarding cervical cancer in at-risk populations directly affects health-seeking behavior and is associated with high mortality among women with cervical cancer. This study aims to evaluate the knowledge of women regarding the causes, risk factors, and prevention strategies of cervical cancer. METHODS: A multistage cross-sectional study of 1,002 women of reproductive age (18-49 years) in Ibadan was conducted. Knowledge of cervical cancer risk causes and prevention strategies was assessed using 13 and 9 question items, respectively. The knowledge score was graded as 0 (no knowledge), 1-4 (poor knowledge), or ≥ 5 (good knowledge). The proportional or partial proportional odds model was used to fit 3 models using the forward stepwise selection. All analysis was performed using Stata 15.0 (Stata Corp, College Station, TX). RESULTS: The median age of participants was 29 years (interquartile range [IQR], 23-35 years). The median knowledge scores of participants on causes and prevention strategies of cervical cancer were 3 (IQR, 0-4) and 3 (IQR, 0-5), respectively. The assessment of knowledge on causes and prevention strategies for cervical cancer revealed that having multiple sexual partners and no previous opportunity for counseling on cervical cancer screening were factors associated with lower odds of knowledge. CONCLUSION: The knowledge of women about the risk factors, causes, and prevention strategies of cervical cancer was poor. It is worrisome that poor knowledge was common among women with potential demographic risk factors for cervical cancer. We recommend innovative community mobilization to improve women's knowledge of the risk factors associated with cervical cancer and prevention strategies.

OBJECTIVE: Fertility is a count data usually rightly skewed and exhibiting large number of zeros than the distributional assumption of the generalized linear models (GLMs). This study examined the robustness of zero-augmented models over GLMs to fit fertility data across regions in Nigeria. The 2013 Nigeria Demographic and Health Survey data were used. The fertility models fitted included: Poisson, negative binomial, zero-inflated Poisson, zero-inflated negative binomial, hurdle Poisson and hurdle negative binomial. Akaike Information Criteria (AIC) and Bayesian Information Criteria (BIC) were used to identify the model with best fit (α = 0.05). RESULTS: The percentage of zero count in the fertility responses were 21.3, 23.9, 31.1, 30.7, 37.6 and 42.4 in North West, North East, North Central, South West, South South and South East regions respectively. In all the six regions in Nigeria, the zero-augmented models were better than the generalized linear models except for North Central. Extensively, the zero-augmented negative binomial based models were of better fit than their Poisson based counterparts; or in rare cases maybe indistinguishable. However, specific family of zero-augmented model is recommended for each region in Nigeria.
