Understanding psychosocial determinants of malaria behaviours in low-transmission settings: a scoping review

BACKGROUND

Recent estimates show progress toward malaria elimination is slowing in many settings, underscoring the need for tailored approaches to fight the disease. In addition to essential structural changes, human behaviour plays an important role in elimination. Engagement in malaria behaviours depends in part on psychosocial determinants such as knowledge, perceived risk, and community norms. Understanding the state of research on psychosocial determinants in low malaria transmission settings is important to augment social and behaviour change practice. This review synthesizes research on psychosocial factors and malaria behaviours in low-transmission settings.

METHODS

A systematic search of peer-reviewed literature and supplemental manual search of grey literature was conducted using key terms and eligibility criteria defined a priori. Publications from 2000-2020 in the English language were identified, screened, and analysed using inductive methods to determine the relationship between the measured psychosocial factors and malaria behaviours.

RESULTS

Screening of 961 publications yielded 96 for inclusion. Nineteen articles collected data among subpopulations that are at increased risk of malaria exposure in low-transmission settings. Purposive and cluster randomized sampling were common sampling approaches. Quantitative, qualitative, and mixed-methods study designs were used. Knowledge, attitudes, and perceived risk were commonly measured psychosocial factors. Perceived response-efficacy, perceived self-efficacy, and community norms were rarely measured. Results indicate positive associations between malaria knowledge and attitudes, and preventive and care-seeking behaviour. Studies generally report high rates of correct knowledge, although it is comparatively lower among studies of high-risk groups. There does not appear to be sufficient extant evidence to determine the relationship between other psychosocial variables and behaviour.

CONCLUSIONS

The review highlights the need to deploy more consistent, comprehensive measures of psychosocial factors and the importance of reaching subpopulations at higher risk of transmission in low transmission contexts. Malaria-related knowledge is generally high, even in settings of low transmission. Programmes and research should work to better understand the psychosocial factors that have been positively associated with prevention and care-seeking behaviours, such as norms, perceived response efficacy, perceived self-efficacy, and interpersonal communication. These factors are not necessarily distinct from that which research has shown are important in settings of high malaria transmission. However, the importance of each factor and application to malaria behaviour change programming in low-transmission settings is an area in need of further research. Existing instruments and approaches are available to support more systematic collection of psychosocial determinants and improved sampling approaches and should be applied more widely. Finally, while human behaviour is critical, health systems strengthening, and structural interventions are essential to achieve malaria elimination goals.

Malaria-Related Psychosocial Factors, Past Antenatal Care-Seeking Behaviors, and Future Antenatal Care-Seeking Intentions by Maternal Age in Malawi and Democratic Republic of the Congo

Young women in sub-Saharan Africa are a group at increased risk for malaria in pregnancy. Early antenatal care (ANC) seeking makes it more likely that women will receive the recommended doses of intermittent preventive treatment of malaria in pregnancy. This study used data from national Malaria Behavior Surveys conducted in Malawi and the Democratic Republic of the Congo (DRC) in 2021 to explore the association between intention to attend ANC in the first trimester for a future pregnancy (early ANC intention) and psychosocial factors among women aged 15-49 years. Eight psychosocial factors related to ANC and based on the ideation model were included, including knowledge, attitudes, and self-efficacy. The study used multivariable logistic regression models controlling for demographic characteristics to evaluate associations between early ANC intention and the individual ideational factors and the composite measure. Analysis included 2,148 women aged 15-49 years (Malawi: 827, DRC: 1,321). Antenatal care ideation was lower among young (aged 15-20 years) than among older (aged 21-49 years) women in Malawi. Young mothers with higher ANC ideation were more likely to intend to attend ANC early in their next pregnancy in both countries. Specific ideational factors associated with intention to attend ANC early varied by country and included positive attitudes, knowledge of ANC, and positive self-efficacy. In Malawi and the DRC, youth-friendly social and behavior change interventions to increase ANC-related ideation could increase future early ANC attendance among young women to improve malaria and birth outcomes.

Ideational factors associated with consistent use of insecticide-treated nets: a multi-country, multilevel analysis

BACKGROUND

Malaria remains a major cause of morbidity and mortality in sub-Saharan Africa. Using insecticide-treated nets (ITNs) every night, year-round is critical to maximize protection against malaria. This study describes sociodemographic, psychosocial, and household factors associated with consistent ITN use in Cameroon, Côte d'Ivoire and Sierra Leone.

METHODS

Cross-sectional household surveys employed similar sampling procedures, data collection tools, and methods in three countries. The survey sample was nationally representative in Côte d'Ivoire, representative of the North and Far North regions in Cameroon, and representative of Bo and Port Loko districts in Sierra Leone. Analysis used multilevel logistic regression and sociodemographic, ideational, and household independent variables among households with at least one ITN to identify correlates of consistent ITN use, defined as sleeping under an ITN every night the preceding week.

FINDINGS

Consistent ITN use in Côte d'Ivoire was 65.4%, 72.6% in Cameroon, and 77.1% in Sierra Leone. While several sociodemographic and ideational variables were correlated with consistent ITN use, these varied across countries. Multilevel logistic regression results showed perceived self-efficacy to use ITNs and positive attitudes towards ITN use were variables associated with consistent use in all three countries. The perception of ITN use as a community norm was positively linked with consistent use in Cameroon and Côte d'Ivoire but was not significant in Sierra Leone. Perceived vulnerability to malaria was positively linked with consistent use in Cameroon and Sierra Leone but negatively correlated with the outcome in Côte d'Ivoire. Household net sufficiency was strongly and positively associated with consistent use in all three countries. Finally, the findings revealed strong clustering at the household and enumeration area (EA) levels, suggesting similarities in net use among respondents of the same EA and in the same household.

CONCLUSIONS

There are similarities and differences in the variables associated with consistent ITN use across the three countries and several ideational variables are significant. The findings suggest that a social and behaviour change strategy based on the ideation model is relevant for increasing consistent ITN use and can inform specific strategies for each context. Finally, ensuring household net sufficiency is essential.

Ideational factors associated with net care behaviour: a multi-country analysis

Background

Malaria is endemic to sub-Saharan African countries. Mass and routine distribution, promotion, and use of ITNs are critical components of malaria prevention programmes. Correct and consistent use of insecticide-treated mosquito nets (ITN) is an effective strategy for malaria prevention. To extend bed-net lifespan, the World Health Organization recommends folding or tying up ITNs when they are not in use. This study analyses factors associated with net care practices in three African countries.

Methods

Researchers collected household data nationwide in Côte d’Ivoire, from the North and Far North regions of Cameroon, and from Port Loko and Bo districts in Sierra Leone, between 2018 and 2019. The dependent variable was respondents reporting that they fold or tie up their nets. The study adjusted for selected sociodemographic, ideational (psychosocial), and household variables using multilevel models. The analysis was limited to women of reproductive age and their male spouses/partners from households with at least one ITN: 2,940 respondents in Cameroon, 6,105 in Côte d’Ivoire, and 2,730 in Sierra Leone.

Results

Among respondents, 50.2% in Cameroon, 52.0% in Côte d’Ivoire and 75.6% in Sierra Leone reported folding or tying up their net when it was not in use. In all three countries, the data showed significant clustering at both household and community levels, indicating the influence of factors operating at these levels on net-care behaviour. The odds of reporting the behaviour varied significantly by geographic unit in each country. Consistent use of nets was strongly correlated with net-care behaviour. Furthermore, five ideational variables were positively associated with the outcome behaviour in all three countries: positive attitude towards net care, perceived susceptibility for malaria, response-efficacy of ITNs, perceived self-efficacy for net use, and the perception that net use was a community norm. Additional significant ideational variables included positive attitudes towards net use (Cameroon and Côte d’Ivoire), perceived severity of malaria (Côte d’Ivoire), and interpersonal communication about malaria (Côte d’Ivoire).

Conclusions

The study identified ideational variables associated with recommended net-care practice. Programme efforts designed to promote net-care practices and extend average lifespan of ITNs may be more effective if they emphasize positive attitudes towards net care, perceived susceptibility of malaria infection, response-efficacy of ITNs, perceived self-efficacy for net use, and promote net-care behaviour as a positive community norm.

The role of ideation on the effect of an SBC intervention on consistent bed net use among caregivers of children under 5 years in Nigeria: a multilevel mediation analysis

Background

Malaria remains a significant public health challenge in Nigeria. Consistent bed net use (sleeping under a treated net every night) has been identified as a key malaria prevention behavior. This paper explores the relationship between mass media social and behavior change interventions, psychosocial factors, and consistent bed net use.

Methods

Data is from the endline survey of a USAID-funded social and behavior change communication campaign conducted from 2012 to 2017 across five states in Nigeria. The outcome measure was consistent bed net use, and the mediator variable was a composite measure called ideation from a set of psychosocial factors believed to influence bed net use. The independent variable was recall of malaria specific media messages. Multilevel mediation analysis explored if recall of malaria specific media messages had any effect on bed net related ideation and if this ideation had any effect on consistent net use.

Results

Respondents included in this study were on average aged 31 years, mostly married or cohabiting (97.5%) and female 75%. Four in 10 (39.7%) respondents were able to recall malaria specific messages. Respondents with low, moderate and high recall were 23, 32 and 80% more likely to have a higher ideational score in the emotional domain compared to those not able to recall. Respondents were more likely to have higher ideational scores in the cognitive domain if they had low (AOR = 1.26, 95% CI 1.15–1.38), moderate (AOR = 1.16, 95% CI 1.00–1.34) or high recall (AOR = 1.55, 95% CI 1.16–2.06), respectively compared to those with no recall. Similarly, respondents with low (AOR = 1.03, 95% CI .99–1.08), moderate (AOR = 1.15, 95% CI 1.08–1.23) and high (AOR = 1.15, 95% CI 1.01–1.30) recall were more likely to have a higher ideational score in the social domain compared to those with no recall. After adjusting for recall of media messages and other potential covariates, all three ideational domains also had a significant positive effect on consistent bed net use. For every unit increase in ideational score, the likelihood of reporting consistent bed net use increased by 5 to 10%. There was a significant indirect effect of recalling malaria specific messages on consistent bed net use through each of the ideational domains.

Conclusion

Access to a bed net is a critical first step in the process of bed net utilization. However, psychosocial factors e.g., emotional, cognitive, and social domains of ideation also play a major role in bed net use. Mass media SBC interventions could potentially influence bed net related ideation and consequently improve net use behavior. Future Social and behavior change interventions should employ approaches that improve these domains of ideation within their audiences in order to increase bed net utilization.

Death registration in Nigeria: a systematic literature review of its performance and challenges

Background

Death registration provides an opportunity for the legal documentation of death of persons. Documentation of deaths has several implications including its use in the recovery of inheritance and insurance benefits. It is also an important input for construction of life tables which are crucial for national planning. However, the registration of deaths is poor in several countries including Nigeria.

Objective

This paper describes the performance of death registration in Nigeria and factors that may affect its performance.

Methods

We conducted a systematic literature review of death registration completeness in Nigeria to identify, characterize issues as well as challenges associated with realizing completeness in death registration.

Results

Only 13.5% of deaths in Nigeria were registered in 2007 which regressed to 10% in 2017. There was no data reported for Nigeria in the World Health Organization database between 2008 and 2017. The country scored less than 0.1 (out of a maximum of 1) on the Vital Statistics Performance Index. There are multiple institutions with parallel constitutional and legal responsibilities for death registration in Nigeria including the National Population Commission, National Identity Management Commission and Local Government Authorities, which may be contributing to its overall poor performance.

Conclusions

We offer proposals to substantially improve death registration completeness in Nigeria including the streamlining and merger of the National Population Commission and the National Identity Management Commission into one commission, the revision of the legal mandate of the new agency to mainly coordination and establishment of standards. We recommend that Local Government authorities maintain the local registries given their proximity to households. This arrangement will be enhanced by increased utilization of information and communications technology in Civil Registration and Vital Statistics processes that ensure records are properly archived.

Correlation of textile 'resistance to damage' scores with actual physical survival of long-lasting insecticidal nets in the field

BACKGROUND

Attempts have been made to link procurement of long-lasting insecticidal nets (LLIN) not only to the price but also the expected performance of the product. However, to date it has not been possible to identify a specific textile characteristic that predicts physical durability in the field. The recently developed resistance to damage (RD) score could provide such a metric. This study uses pooled data from durability monitoring to explore the usefulness of the RD methodology.

METHODS

Data from standardized, 3-year, prospective LLIN durability monitoring for six LLIN brands in 10 locations and four countries involving 4672 campaign LLIN were linked to the RD scores of the respective LLIN brands. The RD score is a single quantitative metric based on a suite of standardized textile tests which in turn build on the mechanisms of damage to a mosquito net. Potential RD values range from 0 to 100 where 100 represents optimal resistance to expected day-to-day stress during reasonable net use. Survival analysis was set so that risk of failure only started when nets were first hung. Cox regression was applied to explore RD effects on physical survival adjusting for known net use environment variables.

RESULTS

In a bivariate analysis RD scores showed a linear relationship with physical integrity suggesting that the proportion of LLIN with moderate damage decreased by 3%-points for each 10-point increase of the RD score (p = 0.02, R2 = 0.65). Full adjustment for net care and handling behaviours as well as other relevant determinants and the country of study showed that increasing RD score by 10 points resulted in a 36% reduction of risk of failure to survive in serviceable condition (p < 0.0001). LLINs with RD scores above 50 had an additional useful life of 7 months.

CONCLUSIONS

This study provides proof of principle that the RD metric can predict physical durability of LLIN products in the field and could be used to assess new products and guide manufacturers in creating improved products. However, additional validation from other field data, particularly for next generation LLIN, will be required before the RD score can be included in procurement decisions for LLINs.

Variation of physical durability between LLIN products and net use environments: summary of findings from four African countries

Background

Physical durability of long-lasting-insecticidal nets (LLIN) is an important aspect of the effectiveness of LLIN as a malaria prevention tool, but there is limited data on performance across locations and products. This secondary analysis of data from the VectorWorks project from 10 sites in four African countries involving six LLIN brands provides such data.

Methods

A total of 4672 campaign nets from 1976 households were recruited into prospective cohort studies 2–6 months after distribution through campaigns and followed for 3 years in Mozambique, Nigeria, DRC and Zanzibar, Tanzania. LLIN products included two 100 denier polyester LLIN (DawaPlus^® 2.0, PermaNet^® 2.0) distributed in five sites and four 150 denier polyethylene LLIN (Royal Sentry^®, MAGNet^®, DuraNet©, Olyset™ Net) distributed in five sites. Primary outcome was LLIN survival in serviceable condition and median survival in years. Net use environment and net care variables were collected during four household surveys. Determinants of physical durability were explored by survival analysis and Cox regression models with risk of failure starting with the first hanging of the net.

Results

Definite outcomes for physical durability were obtained for 75% of study nets. After 31 to 37 months survival in serviceable condition varied between sites by 63 percentage-points, from 17 to 80%. Median survival varied by 3.7 years, from 1.6 to 5.3 years. Similar magnitude of variation was seen for polyethylene and polyester LLIN and for the same brand. Cox regression showed increasing net care attitude in combination with exposure to net related messages to be the strongest explanatory variable of survival. However, differences between countries also remained significant. In contrast, no difference was seen for LLIN material types.

Conclusions

Variation in net use environment and net care is the main reason for differences in the physical durability of LLIN products in different locations. While some of these factors have been identified to work across countries, other factors remain poorly defined and further investigation is needed in this area. Grouping LLIN brands by similar textile characteristics, such as material or yarn strength, is insufficient to distinguish LLIN product performance suggesting a more differentiated, composite metric is needed.

Trends in handwashing behaviours for COVID-19 prevention: Longitudinal evidence from online surveys in 10 sub-Saharan African countries

Handwashing is essential for respiratory virus prevention, but uptake of handwashing in the context of the SARS-CoV-2 pandemic remains under-explored. This study examines trends in and determinants of handwashing practices for COVID-19 prevention in 10 countries in West, East, and Southern Africa. Data are derived from an online global Facebook survey assessing COVID-19 knowledge, attitudes, and practices, fielded in July (Round 1) and November 2020 (Round 2). Adults ≥18 years (N = 29,964) were asked if they practiced handwashing with soap and water in the past week to prevent COVID-19. Design-corrected F-statistics compared knowledge and practice of handwashing, at country and regional levels, between survey rounds. A country-level fixed-effects logistic regression model then identified socio-demographic and ideational correlates of handwashing at Round 2. Most participants were >30 years-old, men, post-secondary educated, and urban residents. Between survey rounds, handwashing prevalence declined significantly across regions and in each country, from a 14% decline (Δ84%-70%) in Tanzania to a 3% decline (Δ92%-89%) in South Africa. Handwashing was higher among participants aged >30 years (Adjusted Odds Ratio [aOR] = 1.25, 95% confidence interval [95%CI]: 1.15-1.35) and with post-secondary education (aOR = 1.62, 95%CI: 1.49-1.77) but lower among men (aOR = 0.71, 95%CI: 0.64-0.78). Ideational factors associated with handwashing included perceived effectiveness of handwashing (aOR = 2.17, 95%CI: 2.00-2.36), knowing someone diagnosed with COVID-19 (aOR = 1.28, 95%CI: 1.18-1.40), and perceived importance of personal action for COVID-19 prevention (aOR = 2.93; 95%CI: 2.60-3.31). Adjusting for socio-demographic and ideational factors, country-level marginal probabilities of handwashing ranged from 67% in Tanzania to 91% in South Africa in Round 2. COVID-19 prevention messages should stress the importance of handwashing, coupled with mask use and physical distancing, for mitigating respiratory disease transmission. Behaviour change communications should be sensitive to resource heterogeneities in African countries, which shape opportunities for sustainable handwashing behaviours.

Racial Disparity in Dental Care during Pregnancy: An Analysis of the Pregnancy Risk Assessment Monitoring System from 2012 to 2015

Black women are less likely to visit dentists during pregnancy than White women when controlling for other socio-demographic variables. Using PRAMS data from 2012 to 2015, we examine the impact of perceived benefits of oral health and dental coverage on Black and White rates of utilizing dental care during pregnancy. Among 61,943 women of ages 20 and older with a recent history of birth in 31 states and New York City, Black women were significantly less likely to visit dentists for cleaning compared with White women. Compared with White women without dental coverage, Black women without dental coverage had more than 30% lower odds of visiting dentists. Analysis of the subpopulation of 1,737 women from five states that implemented additional oral health questions showed that Black women were significantly more likely to have difficulty in finding dentists than White women when controlling for other socio-demographic variables.

Monitoring the durability of the long-lasting insecticidal nets MAGNet and Royal Sentry in three ecological zones of Mozambique

Background

Malaria prevention with long-lasting insecticidal nets (LLINs) has seen a tremendous scale-up in sub-Saharan Africa in the last decade. To sustain this success, it is important to understand how long LLINs remain in the households and continue to protect net users, which is termed durability. This information is needed to decide the appropriate timing of LLIN distribution and also to identify product(s) that may be underperforming relative to expectations. Following guidance from the U.S. President’s Malaria Initiative, durability monitoring of polyethylene 150-denier LLIN (Royal Sentry^® and MAGNet^®) distributed during a 2017 mass campaign in Mozambique was implemented in three ecologically different sites: Inhambane, Tete, and Nampula.

Methods

This was a prospective cohort study in which representative samples of households from each district were recruited at baseline, 1 to 6 months after the mass campaign. All campaign LLINs in these households were labelled and followed up over a period of 36 months. The primary outcome was the “proportion of LLINs surviving in serviceable condition” based on attrition and integrity measures and the median survival in years. The outcome for insecticidal durability was determined by bio-assay from subsamples of campaign LLINs.

Results

A total of 998 households (98% of target) and 1998 campaign LLIN (85% of target) were included in the study. Definite outcomes could be determined for 80% of the cohort LLIN in Inhambane, 45% in Tete, and 72% in Nampula. The highest all-cause attrition was seen in Nampula with 74% followed by Inhambane at 56% and Tete at 50%. Overall, only 2% of campaign LLINs were used for other purposes. Estimated survival in serviceable condition of campaign LLINs after 36 months was 57% in Inhambane, 43% in Tete, and 33% in Nampula, corresponding to median survival of 3.0, 2.8, and 2.4 years, respectively. Factors that were associated with better survival were exposure to social and behavioural change communication, a positive net care attitude, and folding up the net during the day. Larger household size negatively impacted survival. Insecticidal performance was optimal up to 24 months follow-up, but declined at 36 months when only 3% of samples showed optimal effectiveness in Inhambane, 11% in Tete and 29% in Nampula. However, 96% of LLIN still had minimal effectiveness at 36 months.

Conclusions

Differences in median survival could be attributed at least in part to household environment and net care and repair behaviours. This means that in two of the three sites the assumption of a three-year cycle of campaign distributions holds, while in the Nampula site either continuous distribution channels could be expanded or more intense or targeted social and behaviour change activities to encourage net care and retention could be considered.

Comparing the durability of the long-lasting insecticidal nets DawaPlus® 2.0 and DuraNet© in northwest Democratic Republic of Congo

Background

Anecdotal reports from DRC suggest that long-lasting insecticidal nets (LLIN) distributed through mass campaigns in DRC may not last the expected average three years. To provide the National Malaria Control Programme with evidence on physical and insecticidal durability of nets distributed during the 2016 mass campaign, two brands of LLIN, DawaPlus^® 2.0 and DuraNet©, were monitored in neighbouring and similar health zones in Sud Ubangi and Mongala Provinces.

Methods

This was a prospective cohort study of representative samples of households from two health zones recruited at baseline, 2 months after the mass campaign. All campaign nets in these households were labelled, and followed up over a period of 31 months. Primary outcome was the “proportion of nets surviving in serviceable condition” based on attrition and integrity measures and the median survival in years. The outcome for insecticidal durability was determined by bio-assay from subsamples of campaign nets.

Results

A total of 754 campaign nets (109% of target) from 240 households were included in the study. Definite outcomes could be determined for 67% of the cohort nets in Sud Ubangi and 74% in Mongala. After 31 months all-cause attrition was 57% in Sud Ubangi and 76% in Mongala (p = 0.005) and attrition due to wear and tear was 26% in Sud Ubangi and 48% in Mongala (p = 0.0009). Survival in serviceable condition at the last survey was 37% in Sud Ubangi and 17% in Mongala (p = 0.003). Estimated median survival was 1.6 years for the DawaPlus^® 2.0 in Mongala (95% CI 1.3–1.9) and 2.2 years for the DuraNet in Sud Ubangi (95% CI 2.0–2.4). Multivariable Cox proportionate hazard models suggest that the difference between sites was mainly attributable to the LLIN brand. Insecticidal effectiveness was optimal for DuraNet©, but significantly dropped after 24 months for DawaPlus^® 2.0.

Conclusions

In the environment of northwest DRC the polyethylene LLIN DuraNet© performed significantly better than the polyester LLIN DawaPlus^® 2.0, but both were below a three-year median survival. Improvement of net care behaviours should be able to improve physical durability.

Monitoring the durability of the long-lasting insecticidal nets Olyset® and PermaNet® 2.0 in similar use environments in Zanzibar

BACKGROUND

Malaria transmission in Zanzibar has dramatically reduced in recent years but vector control interventions such as long-lasting insecticidal nets (LLIN) must continue to reach malaria elimination. To achieve this, the Zanzibar Malaria Elimination Programme needs actionable evidence of the durability of the LLIN brands distributed. This study compared physical and insecticidal durability of two LLIN brands: Olyset® and PermaNet© 2.0 in two similar districts on the islands of Unguja and Pemba.

METHODS

This was a prospective cohort study of representative samples of households from two districts, recruited at baseline 4 months after the mass campaign. All campaign nets in these households were labelled and followed up over a period of 33 months. Primary outcome was the "proportion of nets surviving in serviceable condition" based on attrition and integrity measures and the median survival in years. The outcome for insecticidal durability was determined by bio-assay from sub-samples of campaign nets.

RESULTS

A total of 834 campaign nets (121% of target) from 299 households were included in the study. Definite outcomes could be determined for 86% of the cohort nets in Unguja (PermaNet® 2.0) and 89% in Pemba (Olyset®). After 33 months, physical survival in serviceable condition was 55% in Unguja and 51% in Pemba. Estimated median survival was lower in Pemba at all time points with 2.3-2.7 years compared to 3.1-3.3 yeas in Unguja. Multivariable Cox proportionate hazard models confirmed the difference between brands (p < 0.0001) and identified household net-care attitude (p = 0.007) and folding of hanging nets during the day (p < 0.0001) as significant determinants, in addition to exclusive use of nets by adults (p = 0.03) and use only over a finished bedframe (p = 0.01). Optimal insecticidal effectiveness was 80% or higher for both brands at all time points when both cone bio-assays and tunnel tests were applied.

CONCLUSIONS

After 3 years of follow-up, Olyset® LLIN showed significantly lower physical survival compared to PermaNet® 2.0 LLIN even after adjusting for other variables of net-use environment and net handling. This suggests that the differences were driven by the textile characteristics of the LLIN brands.

Monitoring the physical and insecticidal durability of the long-lasting insecticidal net DawaPlus® 2.0 in three States in Nigeria

Background

Following guidance from the US President’s Malaria Initiative, durability monitoring of DawaPlus^® 2.0 brand of long-lasting insecticidal net (LLIN) distributed during the 2015/16 mass campaign was set up in three ecologically different states: Zamfara, Ebonyi and Oyo.

Methods

This was a prospective cohort study of representative samples of households from each location, recruited at baseline, 1 to 6 months after the mass campaign. All campaign nets in the households were labelled and followed up over a period of 36 months in Zamfara and Ebonyi and 24 months in Oyo. Primary outcome was the “proportion of nets surviving in serviceable condition” based on attrition and integrity measures and the median survival in years. The outcome for insecticidal durability was determined by bio-assay from sub-samples of campaign nets.

Results

A total of 439 households (98% of target) and 1096 campaign nets (106%) were included in the study. Definite outcomes could be determined for 92% of the cohort nets in Zamfara, 88% in Ebonyi and 75% in Oyo. All-cause attrition was highest in Oyo with 47% no longer present after 24 months, 53% in Ebonyi and 28% in Zamfara after 36 months. Overall only 1% of all campaign nets were used for other purposes. Estimated survival in serviceable condition of the campaign nets was 80% in Zamfara, 55% in Ebonyi (36 months follow-up) and 75% in Oyo (24 months follow-up) corresponding to median survival of 5.3, 3.3, 3.2 years, respectively. Factors associated with better survival were exposure to social messaging combined with a positive net-care attitude and only adult users. Failing to fold the net when hanging and having children under 5 years of age in the household negatively impacted net survival. Insecticidal effectiveness testing at final survey showed knock-down rates of 50–69%, but 24-h mortality above 95% resulting in 100% optimal performance in Ebonyi and Oyo and 97% in Zamfara.

Conclusions

Results confirm the strong influence of net-use environment and behavioural factors in the physical survival of the same LLIN brand, which can increase the time until 50% of nets are no longer serviceable by up to 2 years.

Bringing fear into focus: The intersections of HIV and masculine gender norms in Côte d'Ivoire

This qualitative research study explored the role of masculinity in men's engagement in the HIV care continuum in Côte d'Ivoire. The researchers conducted 73 in-depth interviews and 28 focus group discussions with 227 Ivoirian men between November and December 2016 across three urban sites. Participants in the study expressed that fear was the primary barrier to HIV testing and treatment. These men described five value domains-health, sexuality, work and financial success, family, and social status. Men saw HIV as a direct threat to their agency and strength with respect to each of these value domains, thus shedding light on their reluctance to discover their HIV status through HIV testing. With this data, the researchers created the Masculine Values Framework, a descriptive framework of masculine values that can be applied to better understand the behavior men exhibit in Côte d'Ivoire in the face of HIV. The Masculine Values Framework offers practical guidance for developing gender-sensitive HIV-focused social and behavior change programming in Côte d'Ivoire and similar contexts to reach the UNAIDS 90-90-90 targets.

"You Take Medications, You Live Normally": The Role of Antiretroviral Therapy in Mitigating Men's Perceived Threats of HIV in Côte d'Ivoire

Men diagnosed with HIV face gender-related barriers to initiating and adhering to antiretroviral therapy (ART). This qualitative study (73 in-depth interviews; 28 focus group discussions), conducted with men in three urban sites in Côte d'Ivoire in 2016, examined perceptions of ART, including benefits and challenges, to explore how ART mitigates HIV's threats to men's sexuality, economic success, family roles, social status, and health. Participants perceived that adhering to ART would reduce risk of transmitting HIV to others, minimize job loss and lost productivity, and help maintain men's roles as decision makers and providers. ART adherence was thought to help reduce the threat of HIV-related stigma, despite concerns about unintentional disclosure. While ART was perceived to improve health directly, it restricted men's schedules. Side effects were also a major challenge. Social and behavior change approaches building on these insights may improve male engagement across the HIV care continuum.

Efficacy of a Digital Health Tool on Contraceptive Ideation and Use in Nigeria: Results of a Cluster-Randomized Control Trial

A mobile digital health tool piloted in Kaduna City, Nigeria, was efficacious in promoting positive contraceptive attitudes and encouraging women to adopt a modern contraceptive method, thus showing potential for reducing unmet need in Nigeria.

Background:

Contraceptive prevalence in Nigeria remains among the lowest in the world, which substantially contributes to the country's high maternal and child mortality. Mobile phone technology penetration has increased considerably in Nigeria, opening opportunities for programs to use this medium for reaching their intended audience with health-protective information.

Methods:

In 2017, the Health Communication Capacity Collaborative conducted a cluster-randomized control trial in Kaduna City to assess the efficacy of the digital health tool Smart Client on ideational and behavioral variables related to family planning. Twelve wards in the city were randomly assigned to intervention (6 wards) and control (6 wards) arms of the study. A total of 565 women aged 18–35 years were randomly selected from study wards and consented to participate in the study. At recruitment, the women completed a baseline survey. The women in the intervention group were registered to receive 1 welcome call, 13 program calls, and 3 quiz calls on their mobile phones. Each of the program calls had several segments, including introduction, drama episode, and friend-to-friend chat. The last quiz call included evaluation questions. Women in the control arm received no intervention. The efficacy of the intervention was assessed using both per-protocol and intent-to-treat differences-in-differences techniques.

Results:

The intervention and control arms were equivalent in terms of key sociodemographic characteristics, with the exception of religion. Attrition was a major challenge in the study. On average, participants receiving the intervention listened to 7.2 drama episodes but only 2.6 personal stories and 1.1 sample dialogues. The results of both per-protocol and intent-to-treat analyses show that the intervention was efficacious in improving relevant ideational and behavioral outcomes. For example, the intent-to-treat results show that the intervention increased women's perceived level of confidence to discuss family planning with a provider by 27.7 percentage points and modern contraceptive prevalence by 14.8 percentage points.

Conclusion:

This efficacy assessment showed that using an interactive voice response-based digital tool that includes drama is a viable option for promoting positive ideation about family planning and increasing contraceptive use in Nigeria. Significant lessons learned from this efficacy trial include informing participants at the time of recruitment of what the opening segment of the calls will sound like to avoid the calls being mistaken for telemarketing calls and intensive testing prior to scale-up to avoid potential attrition due to technical issues.

Men's perceptions of HIV care engagement at the facility- and provider-levels: Experiences in Cote d'Ivoire

Men in sub-Saharan Africa have lower rates of HIV testing and are less likely to initiate treatment compared to women. Service delivery dimensions are a key factor in facilitating engagement along the HIV treatment continuum for men and women, yet male specific overall perceptions of the service delivery environment have received little attention in West Africa. This study draws on qualitative data collected in Côte d’Ivoire to explore provider-level and structural factors affecting men’s engagement in HIV testing and treatment through interviews and focus group discussions conducted with health workers and men living with HIV (some on ART) or whose HIV status was unknown. Factors influencing decisions to test or initiate treatment were considered in terms of perceived benefits and costs. Men described costs at the interpersonal (client-provider) level, such as unwanted disclosure or stigma, which were weighed against the potential for social support and clinical guidance. Likewise, fear of unwanted disclosure operated at the facility level, as the layout of facilities sometimes grouped clients living with HIV together. Notably, the benefits men described from engaging in HIV testing and care all operated at the interpersonal level and none at the facility level. In light of the fact that provider- and facility-level factors influenced the perceptions and experiences of men along the treatment continuum, we offer recommendations to reduce barriers to testing and engagement in care related to service delivery.

Healthcare provider interaction and other predictors of long-acting reversible contraception adoption among women in Nigeria

OBJECTIVE

To test the association between healthcare provider communication and adoption of long-acting reversible contraception (LARC) among women in Nigeria.

METHODS

The present cross-sectional observational secondary analysis included women aged 18-49 who were interviewed between June 1 and July 31, 2014, at selected family planning sites in Ibadan and Kaduna, Nigeria. A multivariate generalized estimating equation was utilized to assess the predictors of LARC adoption.

RESULTS

597 women were interviewed, and the study showed that each unit increase on the GATHER index-a self-reported measure of interaction with the provider-was significantly associated with a 16% increased likelihood (adjusted odds ratio [AOR] 1.16, 95% confidence interval [CI] 1.03-1.32) of adopting LARCs. Joint decision making with a partner (AOR 1.51, 95% CI 1.0-2.20), desire to have children in the next 2 years (AOR 0.36, 95% CI 0.18-0.74), whether or not a pregnancy in the next 6 months would be a problem (AOR 1.69, 95% CI 1.16-2.46), and LARC use in the past (AOR 4.15, 95% CI 1.19-14.50) were associated with LARC uptake.

CONCLUSION

Improved patient-provider communication involving patient preferences, information about all methods of contraception, and planned follow-up could play a central role in increasing the demand for, and uptake of, LARCs.

Role of Religious Leaders in Promoting Contraceptive Use in Nigeria: Evidence From the Nigerian Urban Reproductive Health Initiative

Exposure to family planning messages from religious leaders was significantly associated with higher modern contraceptive use, after accounting for background characteristics and other variables such as myths and misconceptions. Engaging religious leaders to support positive social norms is an important strategy to improving voluntary contraceptive use in Nigeria.

Background:

Despite the many supply- and demand-side interventions aimed at increasing contraceptive uptake, the modern contraceptive prevalence rate in Nigeria has remained very low (9.8%). Religion is an important part of the sociocultural fabric of many communities. As such, religious leaders have the power to inhibit or facilitate effective adoption of contraceptive methods to support family health. We assess the association of exposure to religious leaders' tailored scriptural family planning messages with contraceptive use in Nigeria.

Methods:

This cross-sectional study used data from a Measurement, Learning and Evaluation Project survey conducted in 2015 in 4 Nigerian states—Federal Capital Territory, Kaduna, Kwara, and Oyo. The final study sample was restricted to 9,725 non-pregnant women aged 15 to 49 years. Data analysis included descriptive statistics and binary logistic regression analysis to explore significant relationships between current use of a modern contraceptive method, exposure to family planning messages from religious leaders, and selected background characteristics.

Results:

About 2 in 5 women reported being exposed to family planning messages from religious leaders in the past year. Bivariate results revealed a higher uptake of modern contraceptives among women with high exposure to different NURHI interventions (35.5%) compared with respondents in the low or medium exposure categories (14.5% and 24.5%, respectively). The multivariable analysis revealed significantly higher contraceptive uptake among women who had exposure to family planning messages from religious leaders relative to those with no exposure (odds ratio=1.70; 95% confidence interval, 1.54 to 1.87; P<.001). This association remained significant after adjustment for background characteristics and other selected variables.

Conclusion:

Interventions that engage clerics of different faiths as change agents for shaping norms and informing behaviors about family planning and contraceptive use are crucial for increasing contraceptive uptake in Nigeria.

Factors associated with caregivers' consistency of use of bed nets in Nigeria: a multilevel multinomial analysis of survey data

Background

Malaria remains endemic in Nigeria despite programmes and policies put in place toward malaria elimination. Long-lasting insecticidal nets have been documented to offer protection from malaria by preventing mosquito bites. While many studies have examined the factors associated with the use of bed nets in Nigeria and across Africa, little information is available on the factors associated with consistency of use of bed nets.

Methods

The data for this study were derived from a household survey conducted in three states in Nigeria (Akwa Ibom, Kebbi and Nasarawa) between July and September 2015 by the Health Communication Capacity Collaborative, a 5-year cooperative agreement supported by the United States Agency for International Development and the US President’s Malaria initiative and led by the Johns Hopkins Center for Communication Programs. The analysis was limited to a total of 3884 men and women selected from 2863 households with at least one bed net. Multilevel multinomial logistic regression was used to assess the factors associated with consistency of use of bed nets.

Results

The findings revealed 43.2% of the respondents use bed nets every night, while 38.4% use bed nets most nights. The factors associated with using a bed net every night rather than rarely or never using a bed net included sociodemographic and household variables (age, gender, religion, household size, net density, and household wealth), ideational variables (perceptions about severity, susceptibility, self-efficacy to use nets, and response-efficacy of bed net; awareness of place of purchase; willingness to pay for bed nets; attitudes towards net use; and descriptive norm about nets), and state of residence. The three study states differ significantly in terms of most of the independent variables included in the estimated model.

Conclusions

The study recommends that efforts designed to promote consistent use of bed nets should be state-specific and include strategies targeting ideational variables. Furthermore, given the significance of unmeasured heterogeneity at the cluster level, strategies to engage and mobilize the community, such as community dialogue, home visits and engaging community leadership, are relevant.

High-Risk Advanced Maternal Age and High Parity Pregnancy: Tackling a Neglected Need Through Formative Research and Action

Harmful social norms and lack of knowledge contribute to risky pregnancies in older and high-parity women in low- and middle-income countries. A social and behavior change communication resource combining technical guidance with tangible client and provider materials was designed to address and prevent such pregnancies in Niger and Togo.

Pregnancy among women of advanced maternal age (those 35 years or older) or among women of high parity (those having had 5 or more births) is linked to maternal and infant mortality. Yet little is known about the drivers of these pregnancies as they are often neglected in existing family planning and reproductive health programs. To better understand the context in which advanced maternal age and high parity pregnancies occur and the acceptability of discussing associated pregnancy risks, the Health Communication Capacity Collaborative (HC3) conducted formative qualitative research between January and March 2015 on the perception and determinants of such pregnancies in rural and urban areas of Niger and Togo. We supplemented this research with secondary analyses of data from Demographic and Health Surveys and a 2014 Niger survey. Our formative research showed that urban Togolese participants demonstrated more knowledge about advanced maternal age and high parity pregnancy risks than did participants in Niger as a whole. We found that such pregnancies were generally seen as part of reproductive norms in situations where fertility rates remain exceptionally high, especially in Niger. Social, gender, and religious norms, including competition between co-wives, also drove women into high parity and advanced maternal age situations, particularly in Niger, highlighting the need to bring men and community and religious leaders into family planning conversations to increase acceptance. The study also provided important insights needed to address these high-risk pregnancies through culturally appropriate health communication interventions. A main insight was that providers often had incomplete information about advanced maternal age and high parity pregnancies and lacked communication skills, protocols, and tools to appropriately discuss such pregnancy risks with clients. HC3 used these and additional findings to create an Implementation Kit (I-Kit) for family planning and maternal and child health program managers with guidance and tangible tools to address advanced maternal age and high parity pregnancy through social and behavior change communication. The I-Kit includes health communication materials to engage women, men, decision makers, communities, health care providers, journalists, and others. In 2016 and 2017, one organization each in Niger and Togo piloted the I-Kit, integrated selected I-Kit tools into their unique programs, and documented their experiences. Both organizations credited the I-Kit with expanding the scope of their programs to now address advanced maternal age and high parity pregnancy and provided concrete suggestions for adapting the materials according to activity and intended audience.

The effects of nutritional supplementation on body mass index and CD4 count among adult people living with HIV AIDS on antiretroviral treatment in Conakry, Guinea

Whereas the HIV prevalence in Guinea is among the lowest in Africa, many PLHIV in Guinea are malnourished. This study assessed the effect of a nutritional supplementation program on body mass index and CD4 count among adult PLHIV on ART. Study participants were PLHIV who came for consultation in the study sites between May and July 2016. The data came from two sources: retrospectively from participants' medical records and interviews at the time of recruitment into the study. About six months before they were recruited into the study, some of the PLHIV started to receive a monthly nutritional supplementation consisting of Corn-Soy Blend and oil. Analytic methods included bivariate and multivariable methods. The intervention increased the mean BMI by 7.4% and the average current CD4 count by 4.7% compared to nonintervention (P<0.001). Programs in low resource settings should consider nutrition assistance as part of a comprehensive strategy to ensure optimal metabolic and immunological functions among PLHIV.

Correlates of social behavior change communication on care-seeking behaviors for children with fever: an analysis of malaria household survey data from Liberia

Background

In 2010, malaria was responsible for an estimated 41% of deaths among children under the age of five years in Liberia. The same year, the Rebuilding Basic Health Services Project launched “Healthy Baby, Happy Mother,” a social and behavior change communication campaign. The campaign encouraged caregivers to take children under the age of five years to a health facility as soon as children developed fever. This study investigated correlates of two case management outcomes: care-seeking for children under five with fever during the past two weeks and administration of an artemisinin-based combination therapy (ACT) the same or next day as fever onset.

Methods

Data from a 2014 cross-sectional household survey from four counties was used to investigate correlates of two case management outcomes. Using multilevel analysis, the association between these outcomes and a caregiver’s recall of the campaign, her sociodemographic characteristics, and unmeasured characteristics of the community she lived in was investigated.

Results

Caregivers living in Grand Kru County were less likely (OR = 0.21, 95% CI 0.073, 0.632) to take a child to a health facility than those in Bong County. Caregiver recall of the campaign was positively associated with the odds that a child received an ACT promptly (OR 3.62, 95% CI 1.398–9.372), but not with the odds of a caregiver taking a child in their care to a health facility. While unmeasured community-level factors accounted for 19.0% of the variation in the odds that a caregiver’s child was brought to a health facility, they did not play a role in the odds of prompt ACT treatment.

Conclusions

Recalling the “Healthy Mother, Happy Baby” campaign was positively associated with the odds that children received ACT promptly, even in the absence of other malaria prevention and treatment messaging. While caregiver exposure was not associated with care-seeking during the two weeks before interview, prompt care-seeking likely preceded prompt receipt of ACT since most ACT came from health facilities. Unmeasured community-level factors, such as distance from the health facility, may play a role in determining the odds that a caregiver takes a child to a health facility.

Associations between malaria-related ideational factors and care-seeking behavior for fever among children under five in Mali, Nigeria, and Madagascar

Malaria remains one of the leading causes of morbidity and mortality among children under five years old in many low- and middle-income countries. In this study, we examined how malaria-related ideational factors may influence care-seeking behavior among female caregivers of children under five with fever. Data came from population-based surveys conducted in 2014–2015 by U.S. Agency for International Development-funded surveys in Madagascar, Mali, and Nigeria. The outcome of interest was whether a child under five with fever within two weeks prior to the survey was brought to a formal health facility for care. Results show a wide variation in care-seeking practices for children under five with fever across countries. Seeking care for febrile children under five in the formal health sector is far from a norm in the study countries. Important ideational factors associated with care-seeking behavior included caregivers’ perceived social norms regarding treatment of fever among children under five in Nigeria and Madagascar, and caregiver’s knowledge of the cause of malaria in Mali. Findings indicate that messages aimed to increase malaria-related knowledge should be tailored to the specific country, and that interventions designed to influence social norms about care-seeking are likely to result in increased care-seeking behavior for fever in children under five.

Factors affecting the achievement of fertility intentions in urban Nigeria: analysis of longitudinal data

BACKGROUND

Maternal mortality ratio in Nigeria is among the highest in the world with an estimated 160 women dying every day of complications related to pregnancy and childbirth. In addition to appropriate management of complications related to pregnancy and childbirth, preventing unwanted pregnancies is an effective way to reduce maternal deaths. Identifying potentially modifiable factors associated with the achievement of fertility intentions is critical for developing behavior change interventions that will contribute to reducing maternal mortality.

METHODS

The data analyzed came from a longitudinal design with data collected in 2010/2011 and 2014 from the same group of women of reproductive age in six Nigerian cities. The data were collected as part of efforts to evaluate the effects of the Nigerian Urban Reproductive Health Initiative (NURHI). A total of 10,672 women were interviewed at the two points in time but the analyses in this manuscript were limited to 1921 in-union women who reported that they desired no more children at baseline in 2010/2011. The principal analytic method was multivariable regression adjusted for clustering at the enumeration area level. The analysis controlled for socio-demographic and household variables, ideational characteristics, and contraceptive use at baseline.

RESULTS

About two thirds of the women who desired no more children at baseline have neither had any children nor were pregnant at endline. The strongest predictors of the achievement of fertility intentions include parity, age, religion, residence, spousal communication about family size, perceived severity of another pregnancy, and spousal agreement about family size.

CONCLUSION

A comprehensive strategy to help women avoid unwanted pregnancies should include efforts to increase women's understanding about effective ways to prevent unplanned pregnancies and strengthen self-efficacy for contraceptive use. Promoting spousal communication about reproductive issues, engaging men, promoting smaller family sizes and changing pronatalist attitudes should also be part of such a strategy.

Association of Mass Media Communication with Contraceptive Use in Sub-Saharan Africa: A Meta-Analysis of Demographic and Health Surveys

Literature abounds with evidence on the effectiveness of individual mass media interventions on contraceptive use and other health behaviors. There have been, however, very few studies summarizing effect sizes of mass media health communication campaigns in sub-Saharan Africa. In this study, we used meta-analytic techniques to pool data from 47 demographic and health surveys conducted between 2005 and 2015 in 31 sub-Saharan African countries and estimate the prevalence of exposure to family planning-related mass media communication. We also estimated the average effect size of exposure to mass media communication after adjusting for endogeneity. We performed meta-regression to assess the moderating role of selected variables on effect size. On average, 44% of women in sub-Saharan Africa were exposed to family planning-related mass media interventions in the year preceding the survey. Overall, exposure was associated with an effect size equivalent to an odds ratio of 1.93. More recent surveys demonstrated smaller effect sizes than earlier ones, while the effects were larger in lower contraceptive prevalence settings than in higher prevalence ones. The findings have implications for designing communication programs, setting expectations about communication impact, and guiding decisions about sample size estimation for mass media evaluation studies.

Gender-Based Violence following Social Media Acquaintance in Nigeria

In Nigeria, the growth in mobile phone use has provided the opportunity for increased access to the internet, and through this, the social media. The social media in turn offers tremendous communication benefits but also results in some undesirable consequences. One of such is the experience of Gender-Based Violence (GBV). Internet searches using Google Search and Google Scholar in addition to information available to the authors from news media is reported in this study. Five cases were selected for reporting. All cases selected had first contact with their perpetrator(s) on Facebook. The perpetrators were usually men, older than the victims (24-34 years for perpetrators compared with 17-25 years for the victims). The victims experienced physical, psychological, sexual and economic violence from their aggressors. One case resulted in the death of the victim, while two required hospitalization following severe trauma. Three of the victims were raped, while rape was attempted for the other two cases. GBV associated with acquaintances made on social media channels is emerging as a new social problem in Nigeria. Interventions to educate female social media users about this potential danger are urgently necessary.

Correlates of Intra-Household ITN Use in Liberia: A Multilevel Analysis of Household Survey Data

Malaria is a major cause of morbidity and mortality in Liberia. At the same time, insecticide-treated net (ITN) ownership and use remain low. Access is a key determinant of ITN use but it is not the only one; prior studies have identified factors that affect the use of ITNs in households with at least one ITN. These factors operate at the individual, household, and community levels. However, studies have generally not assessed the psychosocial or ideational determinants of ITN use. Using 2014 household survey data, this manuscript examines the socio-demographic, ideational, household, and community factors associated with household member use of ITNs in Liberia. Multilevel modeling was used to assess fixed effects at the individual, household, and community levels, and random effects at the household and cluster levels. The data showed significant residual clustering at the household level, indicating that there were unmeasured factors operating at this level that are associated with ITN use. The association of age with ITN use was moderated by sex such that men, older children, and teenagers were less likely to sleep under an ITN compared to women and children under five years old. Female caregivers' perceived severity of malaria, perceived self-efficacy to detect a complicated case of malaria, and exposure to the "Take Cover" communication campaign were positively associated with ITN use by members of her household. The association with household size was negative, while the relationship with the number of ITNs was positive. Programs should seek to achieve universal coverage (that is, one ITN for every two household members) and promote the notion that everyone needs to sleep under an ITN every night. Programs should also seek to strengthen perceived severity of malaria and educate intended audience groups on the signs of malaria complications. Given the significance of residual clustering at the household level, interventions that engage men as heads of household and key decision-makers are relevant.

Factors associated with HIV infection among sexually experienced adolescents in Africa: a pooled data analysis

The article examines the factors associated with HIV status among adolescents aged 15-19 years in 13 African countries: Côte d'Ivoire, Democratic Republic of Congo, Guinea, Kenya, Liberia, Mali, Malawi, Rwanda, Sierra Leone, Swaziland, Tanzania, Zambia and Zimbabwe. The data were derived from demographic and health surveys or AIDS indicator surveys conducted between 2004 and 2009. The levels of HIV prevalence among adolescents varied considerably across the countries. There was significantly higher HIV prevalence among female adolescents as compared with their male counterparts. For male adolescents, circumcision was the only variable significantly associated with HIV status. Nonetheless, the data suggest that the association between male circumcision and HIV status may be exaggerated. Indeed, regional-level random effects became insignificant once male circumcision was introduced into the estimated models, indicating a strong correlation between unmeasured regional-level factors and male circumcision. For female adolescents, multiple sexual partnerships, time elapsed since sexual debut, marital status, household wealth, and the regional prevalence of male circumcision were strongly and positively associated with HIV status. Moreover, for female adolescents there appear to be significant unmeasured variables operating at the regional level which influence the levels of HIV infection. The implications of the findings for HIV-prevention programming, policy and research are discussed.

Factors associated with contraceptive ideation among urban men in Nigeria

OBJECTIVE

To determine factors influencing the readiness of urban Nigerian men to adopt contraceptive methods.

METHODS

The data were derived from a cross-sectional household survey conducted in Ibadan and Kaduna between September and November 2012. The sample included 2358 men from both cities. An ideation framework was constructed and a multilevel analysis performed to identify factors associated with positive thinking about contraception.

RESULTS

Correlates of ideation operated at the individual, household, and community levels. There is considerable cluster-level variability in ideation score. The key correlates included exposure to family planning promotion campaigns, education, age, religion, marital status, and community norms. Compared with no education, high education is associated with an approximately 6.7-point increase in ideation score (P<0.001). Men with a high level of NURHI program exposure had an average ideation score that was about 3.4 points higher than for their peers with no exposure (P<0.001). The ideation score for Muslims was lower by approximately 1.7 points, on average, than for Christians (P<0.001).

CONCLUSION

A comprehensive strategy of communication and behavior change activities surrounding contraceptive use should be tailored to meet the needs of specific groups of men. Community-level interventions designed to mobilize community members and change social norms that hinder the spread of ideational characteristics that favor contraceptive use should be part of this comprehensive strategy.

The correlates of safe sex practices among Rwandan youth: a positive deviance approach

This paper presents the results of a 2001 sample survey and uses an ideation model to identify the factors affecting primary sexual abstinence and condom use among Rwandan youth. The findings showed that urban residence and age negatively influence primary sexual abstinence and positively affect condom use. Living within the same household as the father tends to protect girls from early sexual experimentation but has no noticeable effect on boys. Moslems are considerably less likely than Christians to report primary sexual abstinence. The use of alcohol tends to be negatively associated with sexual abstinence. The ideational factors that are significant for primary sexual abstinence are perceptions about the sexual behaviours of peers, perceived self-efficacy to refuse sex with someone truly loved, perceived self-efficacy to refuse sex with someone known for more than three months, self-esteem and attitudes toward premarital sex. As for condom use, the ideational variables with significant independent effects on the behavior are: discussion of HIV/AIDS with sexual partner, and to a lesser extent, the perceived self-efficacy to use condoms, and discussion of condom use with the sex partner. The programmatic and policy implications of the results are discussed.

Women's education level, antenatal visits and the quality of skilled antenatal care: a study of three African countries

Many pregnant women in Africa who access professional antenatal care do not receive all the WHO-recommended components of care. Using Demographic and Health Survey (DHS) data from Kenya, Malawi and Nigeria, this study assesses the relationship of education level with the quality of antenatal care received and highlights how the number of antenatal visits mediates this relationship. The results show that a large proportion of the effect of education level on quality of care is direct, while only a small portion is mediated through the number of antenatal visits. Efforts to improve pregnancy outcomes for under-privileged women should focus on removing structural barriers to access, strengthening the technical and interpersonal skills of providers, and addressing providers' biases and discriminatory practices towards these women. Such efforts should also seek to empower underprivileged women to insist on quality antenatal care by explaining what to expect during an antenatal visit.

The use of mediation analysis to assess the effects of a behaviour change communication strategy on bed net ideation and household universal coverage in Tanzania

BACKGROUND

SBCC campaigns are designed to act on cognitive, social and emotional factors at the individual or community level. The combination of these factors, referred to as 'ideation', play a role in determining behaviour by reinforcing and confirming decisions about a particular health topic. This study introduces ideation theory and mediation analysis as a way to evaluate the impact of a malaria SBCC campaign in Tanzania, to determine whether exposure to a communication programme influenced universal coverage through mediating ideational variables.

METHODS

A household survey in three districts where community change agents (CCAs) were active was conducted to collect information on ITN use, number of ITNs in the household, and perceptions about ITN use and ownership. Variables relating to attitudes and beliefs were combined to make 'net ideation'. Using an ideational framework, a mediation analysis was conducted to see the impact exposure to a CCA only, mass media and community (M & C) messaging only, or exposure to both, had on household universal coverage, through the mediating variable net ideation.

RESULTS

All three levels of exposure (CCA, M & C messaging, or exposure to both) were significantly associated with increased net ideation (CCA: 0.283, 95% CI: 0.136-0.429, p-value: <0.001; M & C: 0.128, 95% CI: 0.032-0.334, p-value: 0.018; both: 0.376, 95% CI: 0.170-0.580, p-value: <0.001). Net ideation also significantly increased the odds of having universal coverage (CCAOR: 1.265, 95% CI: 1.118-1.433, p-value: <0.001; M & COR: 1.264, 95% CI: 1.117-1.432, p-value: <0.001, bothOR: 1.260, 95% CI: 1.114-1.428, p-value: <0.001). There were no significant direct effects between any exposure and universal coverage when controlling for net ideation.

CONCLUSIONS

The results of this study indicate that mediation analysis is an applicable new tool to assess SBCC campaigns. Ideation as a mediator of the effects of communication exposure on household universal coverage has implications for designing SBCC to support both mass and continuous distribution efforts, since both heavily rely on consumer participation to obtain and maintain ITNs. Such systems can be strengthened by SBCC programming, generating demand through improving social norms about net ownership and use, perceived benefits of nets, and other behavioural constructs.

Using behavior change communication to lead a comprehensive family planning program: the Nigerian Urban Reproductive Health Initiative

Greater exposure to a comprehensive family planning program in urban Nigeria that emphasized demand generation and communication theory was associated with improved ideation among women (their beliefs, ideas, and feelings about family planning), and more positive ideation was associated with greater contraceptive use, especially among the poor. Improving providers' knowledge, attitudes, and skills was also key. By the end of the observation period, outreach through mobile service delivery contributed nearly one-half of the project clinics' family planning services.

Background:

The Nigerian Urban Reproductive Health Initiative (NURHI), a 6-year comprehensive family planning program (2009–2015) in 4 cities, intentionally applies communication theories to all program elements, not just the demand generation ones, relying mainly on a theory called ideation—the concept that contraceptive use is influenced by people's beliefs, ideas, and feelings and that changing these ideational factors can change people's behavior.

Program Description:

The project used multiple communication channels to foster dialogue about family planning, increase social approval for it, and improve accurate knowledge about contraceptives. Mobile service delivery was started in the third year to improve access to clinical methods in slums.

Methods:

Data from representative baseline (2010–11) and midterm (2012) surveys of women of reproductive age in the project cities were analyzed. We also used propensity score matching to create a statistically equivalent control group of women not exposed to project activities, and we examined service delivery data from NURHI-supported clinics (January 2011–May 2013) to determine the contribution of mobile services to total family planning services.

Results:

Three years into the initiative, analysis of longitudinal data shows that use of modern contraceptives has increased in each city, varying from 2.3 to 15.5 percentage points, and that the observed increases were predicted by exposure to NURHI activities. Of note is that modern method use increased substantially among the poorest wealth quintiles in project cities, on average, by 8.4 percentage points. The more project activities women were exposed to, the greater their contraceptive use. For example, among women not using a modern method at baseline, contraceptive prevalence among those with no exposure by midterm was 19.1% vs. 43.4% among those with high exposure. Project exposure had a positive dose-response relationship with ideation, as did ideation and contraceptive use. By the end of the observation period, mobile services were contributing nearly 50% of total family planning services provided through NURHI-supported clinics. Propensity score matching found that the increase in contraceptive use in the 4 cities attributable to project exposure was 9.9 percentage points. Intention to use family planning in the next 12 months also increased by 7.5 to 10.2 percentage points across the 4 cities.

Conclusion:

Demand-led family planning programs, in which demand generation is the driving force behind the design rather than the conventional, service delivery-oriented approach, may be more suitable in places where expressed demand for contraceptives is low.

Determinants of concurrent sexual partnerships within stable relationships: a qualitative study in Tanzania

OBJECTIVE

Concurrent sexual partnerships (CP) have been identified as a potential driver in the HIV epidemic in southern Africa, making it essential to understand motivating factors for engagement in CP. We aimed to assess community attitudes and beliefs about relationship factors that influence men and women in stable relationships to engage in CP in Tanzania. Social exchange theory was used for interpreting the data.

DESIGN

Qualitative study with focus group discussions (FGDs).

SETTING

Semiurban/rural communities in four regions across Tanzania (Dar es Salaam, Shinyanga, Iringa and Mbeya).

PARTICIPANTS

120 women aged 17-45 years and 111 men aged 18-49 years from four study areas participated in 32 FGDs.

OUTCOME MEASURES

FGD participants were asked the following questions about CP: definitions and types, motivations and justifications for engaging or not engaging, cultural factors, gender and socialisation, and local resources and efforts available for addressing CP. Our analysis focused specifically on beliefs about how relationship factors influence engagement in CP.

RESULTS

Dissatisfaction with a stable relationship was believed to be a contributing factor for engagement in CP for both men and women. Participants more commonly reported financial dissatisfaction as a contributing factor for women engaging in CP within stable relationships, whereas emotional and sexual dissatisfaction were reported as contributing factors for men and women. Furthermore, participants described how potential outside partners are often evaluated based on what they are able to offer compared with stable partners.

CONCLUSIONS

Efforts to reach men and women in stable relationships with HIV prevention messages must consider the various dimensions of motivation for engaging in CP, including relationship dynamics.

Descriptive and injunctive norms related to concurrent sexual partnerships in Malawi: implications for HIV prevention research and programming

Concurrent sexual partnerships are hypothesized to be a contributing factor to Malawi's HIV epidemic. As social norms influence health behavior and have been found to influence sexual behavior, the purpose of this study was to explore two types of norms, descriptive and injunctive norms, toward concurrent sexual partnerships in Malawi. Data from 40 focus group discussions and 20 in-depth interviews conducted in five districts in Malawi, which included 318 participants aged 18-55 years, were analyzed. Participants perceived that concurrent sexual partnerships were extremely common, and believed that very few individuals in their communities were not in concurrent sexual partnerships. However, participants perceived that others in their communities heavily disapproved of concurrent sexual partnerships outside of polygamy, as polygamy was viewed as an acceptable type of partnership because it was conducted in the open. Participants asserted that there were no traditional practices that promoted concurrent sexual partnerships, and perceived that those that engaged in the behavior were for the most part stigmatized by community members. Further research is needed to obtain a thorough understanding of the way in which the perceived actions and beliefs of peers influence the beliefs, feelings and actions of individuals to strengthen HIV programming efforts in the region.

Predictors of parent-child communication among a nationally representative sample in Nigeria

This study explores what constructs are associated with parent-adolescent communication about AIDS/sexually transmitted infections (STIs) and sexual relationships in Nigeria. The analyses use data from the 2007 National HIV/AIDS and Reproductive Health Survey on 2593 men and women who had at least one child over the age of 12 years. The respondents were classified as low, medium, or high communicators. Low communicators were parents who did not talk to their child about either AIDS/STIs or sexual relationships. Medium communicators were parents who discussed only one topic with at least one child. High communicators were parents who discussed both topics with at least one child. Logistic regression was used to compare high communicators with low/medium communicators. There are commonalities and differences among men and women in the factors associated with parent-adolescent communication. Age, religion, and knowing where to obtain information about HIV/AIDS were associated with the extent of communication, regardless of the parent's gender. Perceived social support was an important correlate for fathers, while knowledge of female STI symptoms showed a significant association only for mothers. Programmatic and communication implications of the findings include addressing men and women differently, developing strategies to specifically reach younger parents and Muslims, and increasing general awareness of HIV/AIDS information resources. Further research is needed to understand the context, content, and timing of parent-adolescent conversations about AIDS/STIs and sexual relationships and how these factors affect the sexual behaviors of adolescents.

Community perspectives on parental influence on engagement in multiple concurrent sexual partnerships among youth in Tanzania: implications for HIV prevention programming

Although concurrent sexual partnerships (CPs) have been hypothesized to be an important risk factor for HIV in sub-Saharan Africa, the social and cultural factors that encourage CPs are not well understood. This study explored the community's perspectives on the role that parents can play in influencing their children's decision to engage in CPs. We conducted 16 in-depth interviews, 32 focus group discussions, and 16 key informant interviews with 280 adult participants in Tanzania. Data were coded; findings and conclusions were developed based on themes that emerged from coding. Three parental influences on CPs emerged: parent-child communication about sex, both silent and explicit encouragement of CPs, and parental behavior modeling. Parents are typically either too busy or too "embarrassed" to talk with their children about sex and CPs. The information parents do give is often confusing, fear-based, inadequate, and/or only focused on daughters. Parents themselves also encourage CPs through complicity of silence when their daughters come home with extra cash or consumer goods. In some cases, parents overtly encourage their children, particularly daughters, to practice CPs due to the promise of money from wealthy partners. Finally, when parents engage in CPs, the children themselves learn to behave similarly. These results suggest that parents can influence their children's decision to engage in CPs. HIV prevention interventions should address this by promoting parent-child communication about sexuality; associated disease risks and gender-equitable relationships; promoting positive parental role modeling; and educating parents on the implications of encouragement of CPs in their children.

Maternal reasons for non-immunisation and partial immunisation in northern Nigeria

AIM

To compare maternal reasons for non-immunisation and for partial immunisation in northern Nigeria, and determine the link between specific reasons and future intentions to immunise.

METHODS

Responses to open-ended questions collected through a 2007 questionnaire survey were individually coded for key words using the regexm command in Stata (StataCorp, College Station, TX, USA). Simple percentages are used to analyse the differences in reasons for non-immunisation and partial immunisation. Logistic regression serves to assess the relationship between specific reasons for non-immunisation and future intentions to immunise.

RESULTS

The reasons for non-immunisation generally differ from those advanced for partial immunisation. In general, reasons for non-immunisation have to do with ideational and normative factors. In contrast, supply-side factors are the reasons most often advanced for partial immunisation, although lack of knowledge also plays a strong role. Some reasons for non-immunisation are more compatible with future intention to immunise than others.

CONCLUSIONS

Efforts to promote the uptake of immunisation need to address both demand- and supply-side factors. Increasing knowledge about immunisation, changing negative attitudes about immunisation, debunking myths and rumours about immunisation, and addressing religious, ethnic and political bases for resistance to immunisation are necessary to encourage parents to initiate child immunisation. To promote timely completion of immunisation schedule, programmes will need to improve vaccine supply, strengthen provider's capacity for quality service and increase community knowledge about immunisation.

Determinants of use of maternal health services in Nigeria--looking beyond individual and household factors

BACKGROUND

Utilization of maternal health services is associated with improved maternal and neonatal health outcomes. Considering global and national interests in the Millennium Development Goal and Nigeria's high level of maternal mortality, understanding the factors affecting maternal health use is crucial. Studies on the use of maternal care services have largely overlooked community and other contextual factors. This study examined the determinants of maternal services utilization in Nigeria, with a focus on individual, household, community and state-level factors.

METHODS

Data from the 2005 National HIV/AIDS and Reproductive Health Survey - an interviewer-administered nationally representative survey - were analyzed to identify individual, household and community factors that were significantly associated with utilization of maternal care services among 2148 women who had a baby during the five years preceding the survey. In view of the nested nature of the data, we used multilevel analytic methods and assessed state-level random effects.

RESULTS

Approximately three-fifths (60.3%) of the mothers used antenatal services at least once during their most recent pregnancy, while 43.5% had skilled attendants at delivery and 41.2% received postnatal care. There are commonalities and differences in the predictors of the three indicators of maternal health service utilization. Education is the only individual-level variable that is consistently a significant predictor of service utilization, while socio-economic level is a consistent significant predictor at the household level. At the community level, urban residence and community media saturation are consistently strong predictors. In contrast, some factors are significant in predicting one or more of the indicators of use but not for all. These inconsistent predictors include some individual level variables (the woman's age at the birth of the last child, ethnicity, the notion of ideal family size, and approval of family planning), a community-level variable (prevalence of the small family norm in the community), and a state-level variable (ratio of PHC to the population).

CONCLUSION

Factors influencing maternal health services utilization operate at various levels - individual, household, community and state. Depending on the indicator of maternal health services, the relevant determinants vary. Effective interventions to promote maternal health service utilization should target the underlying individual, household, community and policy-level factors. The interventions should reflect the relative roles of the various underlying factors.

Factors predicting BCG immunization status in northern Nigeria: a behavioral-ecological perspective

This study examines the predictors of Bacille Calmette-Guérin (BCG) immunization status among infants in northern Nigeria using a behavioral-ecological model. The findings show only 37.3 percent of the children had received BCG vaccine, and reveal that BCG immunization status in northern Nigeria is influenced by multiple layers of factors, including child's characteristics, parental or household factors, community characteristics, vaccine supply and the policy environment. At the child's level, place of birth and ownership of an immunization card are the two most significant predictors. The parental and household predictors of BCG immunization status include maternal use of antenatal care, maternal knowledge about immunization, maternal exposure to child health information, social influence and paternal approval of immunization. Both the regularity of vaccine supply to the health facility and the state of residence are associated independently with BCG immunization status. These findings stress the need for interventions at multiple levels in order to increase BCG immunization status.

The effects of a communication program on contraceptive ideation and use among young women in northern Nigeria

This study assesses the effects of a communication campaign designed to encourage young people in northern Nigeria to use modern family planning methods to avoid unwanted pregnancies. The analyses are based on a sample of 819 sexually experienced women. Using multivariate probit regression, we attempt to correct for possible endogeneity among campaign exposure, contraceptive ideation, and contraceptive use. Our analysis reveals that the direct effect of campaign exposure on the probability of contraceptive use is only marginally significant, but the effect of exposure on contraceptive ideation is robust, as is the effect of contraceptive ideation on contraceptive use. The findings demonstrate not only the success of the program but also the relevance of incorporating ideation into analytic models assessing the effects of communication campaigns.

Determinants of the uptake of the full dose of diphtheria-pertussis-tetanus vaccines (DPT3) in Northern Nigeria: a multilevel analysis

OBJECTIVES

Health behaviors are influenced by an array of factors at the individual, household, community and societal levels. This paper examines the relative contribution of child's characteristics, mother's attributes, household profiles and community factors on the probability that a child will receive the full series of diphtheria-pertussis-tetanus vaccines (DPT3) as a proxy for full immunization.

METHODS

We used data from a 2004 household survey conducted in three northern Nigeria states: Borno, Kano and Yobe. We estimated multilevel models with fixed effects specified at the individual, household and community levels, and random effects at the community level.

RESULTS

Overall, only 16.0% of the children aged 12-35 months had received DPT3. The data show that a significant amount of the variation in DPT3 uptake occurs at the community level. The most significant predictors of the uptake of DPT3 are found at multiple levels and include child's place of birth, presence of an immunization card, mother's ideation, mother's decision-making power and perceived social approval of immunization. The data further show that significant community-level variations in immunization uptake remain even after individual and household factors have been considered.

CONCLUSIONS

The data reveal that childhood immunization is influenced by norms and unmeasured factors at the community level in addition to factors operating at the level of the individual child and the household. Strategies for improving the uptake of immunization should include culturally appropriate interventions that target multiple levels of influences. Improving parental attitudes towards immunization without addressing the issue of community norms is not likely to yield significant results.

Readiness for HIV testing among young people in northern Nigeria: the roles of social norm and perceived stigma

This study examined the predictors of readiness for HIV testing among young people in northern Nigeria, paying special attention to the role of stigma. Stigma is measured at two levels: individual and community (social norm). There are commonalities and differences in the correlates of readiness among men and women. For men and women, knowledge about HIV prevention, knowledge about a source for VCT, discussion about condom use for HIV prevention and perceived risk are strong predictors. Knowledge that an apparently healthy person can be HIV-infected is only significant for women. Perceived stigma is a significant predictor for both men and women although the specific dimension of note differs between the sexes. Social norm is strongly and directly associated with readiness among men but has no apparent influence among women. For both sexes, social norm appears to have strong mediating influence on the relationship between personal perceived stigma and readiness. The results strongly suggest that to eliminate HIV-related stigma, it is not enough to target individual cognitive processes; strategic efforts should target social structures in order to change negative social norms.

Impact of a communication programme on female genital cutting in eastern Nigeria

OBJECTIVES

This study describes a female genital cutting (FGC) elimination communication programme in Enugu State and assesses its impact in changing relevant knowledge, attitudes and behavioural intentions.

METHODS

The FGC programme combined a community mobilization component with targeted advocacy and mass media activities. Data for assessing the impact of the programme derived from baseline and follow-up surveys in three intervention local government areas (LGA) in Enugu State and three comparison LGAs in Ebonyi State. An ideation model of behaviour change guided the analyses of the impact of the programme on personal advocacy for FGC, perceived self-efficacy to refuse pressure to perform FGC, perceived social support for FGC discontinuation, perceived benefits of FGC, perceived health complications of FGC and intention not to perform FGC on daughters. The analytical methods include comparing change in pertinent outcome variables from baseline to follow-up in the two study states and using logistic regression on follow-up data for the intervention state to assess the link between programme exposure and the relevant outcome indicators.

RESULTS

The data show that while the pertinent ideational factors and the intention not to perform FGC either worsened or remained stagnant in Ebonyi State, they improved significantly in Enugu State. The logistic regression results show that programme exposure is associated with the expected improvements in all the pertinent indicators.

CONCLUSION

The multimedia communication programme has been effective in changing FGC-related attitudes and promoting the intention not to perform FGC.
