Prevalence of different variations of non-consented care during the childbirth process in Mexico by geographical regions: comparing ENDIREH survey data from 2016 to 2021

INTRODUCTION

Non-consented care, a form of obstetric violence involving the lack of informed consent for procedures, is a common but little-understood phenomenon in the global public health arena. The aim of this secondary analysis was to measure the prevalence and assess change over time of non-consented care during childbirth in Mexico in 2016 and 2021, as well as to examine the association of sociodemographic, pregnancy-, and childbirth-factors with this type of violence.

METHODS

We measured the prevalence of non-consented care and three of its variations, forced sterilization or contraception, forced cesarean section, and forced consent on paperwork, during childbirth in Mexico for 2016 (N = 24,036) and 2021 (N = 19,322) using data from Mexico's cross-sectional National Survey on the Dynamics of Household Relationships (ENDIREH). Weighted data were stratified by geographical regions. We performed adjusted logistic regression analyses to explore associations.

RESULTS

The national prevalence of non-consented care and one of its variations, pressure to get a contraceptive method, increased from 2016 to 2021. A decrease in the prevalence was observed for forced contraception or sterilization without knowledge, forcing women to sign paperwork, and non-consented cesarean sections nationally and in most regions. Women between the ages of 26 and 35 years, married, cohabiting with partner, living in urban settings, who do not identify as Indigenous, and who received prenatal services or gave birth at the Mexican Institute of Social Security (IMSS) facilities experienced a higher prevalence of non-consented care. Being 26 years of age and older, living in a rural setting, experiencing stillbirths in the last five years, having a vaginal delivery, receiving prenatal services at IMSS, or delivering at a private facility were significantly associated with higher odds of reporting non-consented care.

CONCLUSION

While a decrease in most of the variations of non-consented care was found, the overall prevalence of non-consented care and, in one of its variations, pressure to get contraceptives, increased at a national and regional level. Our findings suggest the need to enforce current laws and strengthen health systems, paying special attention to the geographical regions and populations that have experienced higher reported cases of this structural problem.

Using Responsive Feedback in Scaling a Gender Norms-Shifting Adolescent Sexual and Reproductive Health Intervention in the Democratic Republic of Congo

PROGRAM DESCRIPTION

Growing Up GREAT! (GUG) is a sexual and reproductive health (SRH) program for adolescents aged 10-14 years in Kinshasa, Democratic Republic of the Congo (DRC). The multilevel program takes an ecological approach to foster community examination of gender inequitable norms and to increase adolescents' SRH knowledge, skills, and gender-equitable attitudes. GUG design, piloting, and scale-up were informed by a theory of change and responsive feedback mechanisms (RFMs) during piloting and scale-up.

RESPONSIVE FEEDBACK MECHANISMS

The program engaged stakeholders via quarterly learning meetings to review monitoring data, evaluation results, and practice-based knowledge and to subsequently identify challenges and develop solutions. The program commissioned rapid research on specific intervention elements to improve implementation and documented scale-up learnings using the World Health Organization/ExpandNet framework.

ACHIEVEMENTS

RFMs used in the pilot period allowed the program to address community concerns by intensifying orientation activities with parents and schools, shifting the calendar of activities to increase male engagement, and increasing facilitator training length to improve facilitation quality. Using RFMs during scale-up prompted further adaptations for program sustainability, including recommendations for task-shifting from NGO facilitators to community health workers.

CONCLUSION

GUG used RFMs from pilot through scale-up to foster a learning culture among local partners, implementers at headquarters, and global research partners. Using responsive feedback (RF) enabled timely response to the evolving implementation context, resulting in strategic program adaptations that fostered increased community support of the project. Other successes due, at least in part, to this RF approach include incorporation of the program into DRC's national adolescent health strategy, and rapid response to the COVID-19 pandemic in educational strategies for program beneficiaries.

Adolescent alcohol use: use of social network analysis and cross-classified multilevel modeling to examine peer group, school, and neighborhood-level influences

Background: Neighborhood-, school-, and peer-contexts play an important role in adolescent alcohol use behaviors. Methodological advances permit simultaneous modeling of these contexts to understand their relative and joint importance. Few empirical studies include these contexts, and studies that do typically: examine each context separately; include contexts for the sole purpose of accounting for clustering in the data; or do not disaggregate by sex.Objectives: This study takes an eco-epidemiologic approach to examine the role of socio-contextual contributions to variance in adolescent alcohol use. The primary parameters of interest are therefore variance rather than beta parameters (i.e. random rather than fixed effects). Sex-stratified models are also used to understand how each context may matter differently for male and female adolescents.Method: Data come from the National Longitudinal Study of Adolescent to Adult Health (n = 8,534 females, n = 8,102 males). We conduct social network analysis and traditional and cross-classified multilevel models (CCMM) in the full and sex-disaggregated samples.Results: In final CCMM, peer groups, schools, and neighborhoods contributed 10.5%, 10.8%, and 0.4%, respectively, to total variation in adolescent alcohol use. Results do not differ widely by gender.Conclusions: Peer groups and schools emerge as more salient contributing contexts relative to neighborhoods in adolescent alcohol use for males and females. These findings have both methodological and practical implications. Multilevel modeling can model contexts simultaneously to prevent the overestimation of variance in youth alcohol use explained by each context. Primary prevention strategies addressing youth alcohol use should focus on schools and peer networks.

Balancing Quality, Intensity and Scalability: Results of a Multi-level Sexual and Reproductive Health Intervention for Very Young Adolescents in Kinshasa

PURPOSE

In addition to the rapid physical and cognitive transformations very young adolescents (VYAs) experience between ages 10-14, gender and social norms internalized during this period have long-term implications as adolescents become sexually active. This age presents critical opportunities for early intervention to promote gender-equitable attitudes and norms for improved adolescent health.

METHODS

In Kinshasa, DRC, Growing Up GREAT! implemented a scalable approach to engage in- and out-of-school VYAs, caregivers, schools, and communities. A quasi-experimental study evaluated the outcomes of sexual and reproductive health (SRH) knowledge, assets and agency, and gender-equitable attitudes and behaviors among VYA participants. Ongoing monitoring and qualitative studies provided insights into implementation challenges and contextual factors.

RESULTS

Results show significant improvement in SRH knowledge and assets such as caregiver connectedness, communication, and body satisfaction among the intervention group. The intervention was also associated with significant improvements in gender-equitable attitudes related to adolescents' household responsibilities and decreased teasing and bullying. Intervention effects on awareness of SRH services, body satisfaction, chore-sharing, and bullying were stronger for out-of-school and younger VYAs, suggesting the intervention's potential to increase positive outcomes among vulnerable adolescents. The intervention did not shift key gender norm perceptions assessed. Implementation research suggests design decisions made to increase the intervention's scalability necessitated reductions in training and program dosing that may have affected results.

DISCUSSION

Results affirm the potential of early intervention to increase SRH knowledge, assets and gender-equitable behaviors. They also highlight the need for more evidence on effective program approaches and segmentation for shifting VYA and SRH norms.

The Impacts of Two Gender-Transformative Interventions on Early Adolescent Gender Norms Perceptions: A Difference-in-Difference Analysis

PURPOSE

Inequitable gender norms are widespread and can be harmful to the wellbeing of adolescents. This study estimates the effects of two gender-transformative interventions, Semangat Dunia Remaja or Teen Aspirations (SETARA) and Growing Up Great! (GUG!), on gender norms perceptions and attitudes among very young adolescents in poor urban settings in Bandar Lampung, Semarang, Denpasar (Indonesia), and Kinshasa (Democratic Republic of the Congo).

METHODS

The study draws from the longitudinal Global Early Adolescent Study, using a quasi-experimental design to evaluate the interventions. Data collection took place between 2017 and 2020. Our analytical samples included 2,159 adolescents in Kinshasa and 3,335 in Indonesia. We conducted a difference-in-difference analysis using generalized estimation equations and generalized linear models, after stratification by site and sex.

RESULTS

The interventions shifted a range of gender perceptions, although effects varied by program, city, and sex. SETARA shifted gender-normative perceptions related to traits, roles, and relations, while GUG! effects were more concentrated on attitudes toward chore sharing. SETARA was most effective in Semarang and Denpasar, but not in Bandar Lampung. In addition, both interventions were more consistently effective for girls than boys.

DISCUSSION

Gender-transformative interventions can effectively promote gender equality in early adolescence, but effects are program-specific and context-specific. Our findings emphasize the importance of defined theories of change and consistent implementation in gender-transformative intervention.

Understanding How Gender Transformative Interventions Affect Adolescent Sexuality: A Cross-Cultural Perspective

PURPOSE

Early adolescence is a critical period for developing healthy sexual and reproductive health (SRH) knowledge, attitudes, and behaviors. However, a gap exists in interventions targeting very young adolescents that encompass the multilevel influences impacting healthy sexuality. This examination of two SRH programs in Indonesia and the Democratic Republic of Congo will elucidate facilitators and barriers to improving young adolescent sexuality.

METHODS

The Growing Up Great! (GUG) intervention in the Democratic Republic of Congo and Semangat Dunia Remaja or Teen Aspirations intervention in three districts in Indonesia were evaluated using the Global Early Adolescent Study survey. Adolescents were interviewed in 2017 and one year later in Kinshasa (n = 2,519). In Indonesia, baseline in 2018 was follow-up in 2020 in Bandar Lampung (n = 948), Denpasar (n = 1,156), and Semarang (n = 1,231). Outcomes included SRH knowledge and communication, awareness of SRH services, and attitudes about sexuality. Analysis followed a difference-in-difference approach to compare changes in each outcome over time between interventions and controls.

RESULTS

Both interventions improved pregnancy and HIV knowledge, while Semangat Dunia Remaja or Teen Aspirations also improved SRH communication. Results differed by site in Indonesia, with Semarang, the site that adhered most closely to intervention design, observed the most improvements. Differential effects were also seen by gender, especially in Kinshasa where girls advanced in SRH communication and knowledge but not boys. Girls in Semarang shifted normative SRH attitudes, and boys in Denpasar improved knowledge.

DISCUSSION

Interventions targeting very young adolescents can improve SRH knowledge, communication, and attitudes, though impact depends on context and implementation. Future programs should incorporate the community and environment influencing adolescent experiences with sexuality.

Do gender-equitable attitudes translate to gender-equitable chore-sharing behavior? A sex-stratified longitudinal analysis among adolescents in Kinshasa

Unpaid care work is disproportionately performed by women and girls, negatively impacting their ability to engage in educational, social, and economic opportunities. Despite calls to address these inequities, empirical evidence on interventions designed to shift gender attitudes is limited, especially within adolescent populations. To address this gap, we used longitudinal data to conduct difference-in-difference and logistic regression models to examine the impact of a norms-shifting intervention in Kinshasa on adolescent gender-equitable chore-sharing attitudes. As compared to controls, intervention participants were 2.3 times (p <0.001) more likely to hold gender-equitable attitudes towards chore-sharing at end line. Using baseline attitudes to predict end line behavior, we find that, as compared to adolescents with gender-inequitable attitudes, boys and girls who espoused equitable gender attitudes were 1.9 times (p <0.001) and 1.5 times (p=0.005), respectively, more likely to report gender-equitable chore-sharing behavior. Norms-shifting interventions should be prioritized among very young adolescents as a strategy to shift gender-inequitable attitudes.

Understanding the Roles of Sport and Alcohol Use in Adolescence on Physical and Sexual Intimate Partner Violence Perpetration in Young Adulthood: Findings From a Sex-Stratified Multilevel Analysis

Adolescent peer groups shape beliefs that dictate behavioral norms, including intimate partner violence (IPV) perpetration behaviors, with lasting influence into adulthood. This study examines the role of sport engagement and alcohol use in adolescence on perpetration of physical and sexual IPV in young adulthood. A secondary data analysis was conducted with data from 3411 male and 4318 female participants in the National Longitudinal Study of Adolescent to Adult Health study. Sports and other school activity participation, as well as alcohol use, were measured in middle and high school students. Intimate partner violence perpetration was measured six years later with items from the revised Conflict Tactics Scales. Sex-stratified logistic cross-classified multilevel analyses indicate that, for males, participation in football in adolescence was associated with higher odds of IPV perpetration in young adulthood (aOR:1.26, p = .01). For males and females, non-engagement in any school activities in adolescence was associated with higher odds of IPV perpetration in young adulthood (male aOR: 1.52, p < .01; female aOR: 1.19, p = .04). Alcohol use in adolescence was also associated with higher odds of IPV perpetration in young adulthood for both males and females, even when low level drinking (1-2 drinks in the past 12 months) was reported (male aOR: 1.40, p < .01; female aOR: 1.38, p < .01). Random-effect estimates indicate small but significant contributions of adolescent peer, school, and neighborhood contexts on IPV perpetration in young adulthood for both boys and girls. These findings highlight that football engagement among boys, and alcohol use among boys and girls, are linked to longer-term risk for IPV perpetration, but engagement in other sports and school activities appear to serve as protective factors. These findings, taken with those regarding social context effects, suggest that positive social environment and networks in adolescence, inclusive of those offered in some sports, can be useful platforms for IPV prevention efforts.

Prevention of Sexual Violence in sport: A Socioecological Review

Sexual violence in sport is prevalent and represents a serious public health concern. The social-ecological model for health promotion has been used successfully as a framework to identify individual-to-policy level factors aimed at health promotion or disease prevention. The purpose of this review was to examine both published and non-published (publicly available) SVP efforts conducted within the context of sport and make recommendations for future practice. Grey literature search methods were utilized to conduct a review of publicly available documents. This included (a) a comprehensive Google search using unique search terms that would identify SVP efforts within sport settings and (b) a review of the publicly accessible websites identified in the previous step. Following the grey literature search, and using the SVP practices identified in step one, we conducted a supplementary literature search using scientific publication search engines to identify whether the SVP practices identified in step one had associated peer-reviewed publications. Finally, we assessed various characteristics of each SVP practice including the target population, age range of intended participants, and whether the SVP had associated peer review publications. This led to the identification of 35 unique SVP practices: 25 (71%) SVP practices were assigned to the Intrapersonal level, 6 (17%) were assigned to the Interpersonal level, 9 (26%) were assigned to the Organizational level, 3 (9%) were assigned to the Community, and 2 (6%) were assigned to the Policy level. This review uncovered several important findings including a lack of multi-level SVP practices within sport, a lack of SVP practices that target children, minimal programming aimed at specifically preventing perpetration, the need to elevate policy level action, and a lack of peer-reviewed literature. Ultimately findings suggest that sport organizations ought to prioritize sexual violence prevention using national organizations for guidance.

The power of women's and men's Social Networks to catalyse normative and behavioural change: evaluation of an intervention addressing Unmet need for Family Planning in Benin

Background

In Benin, despite good knowledge and availability, modern contraceptive prevalence remains relatively low, and the unmet need for family planning is relatively high. This is partly due to insufficient attention to socio-normative barriers that influence need and method use. Applying social network theory, Tékponon Jikuagou (TJ) aims to reduce socio-normative barriers preventing modern contraceptive use in rural Benin. After community identification, TJ trains influential network actors who encourage critical dialogue about unmet need, family planning, gender, and other social norms within their networks, complemented by radio and services linkages. This paper evaluates TJ's effectiveness and how intervention components affect intermediate and primary FP outcomes.

Methods

We report findings from pre/post-intervention cross-sectional research with a comparison group conducted at baseline with 1,043 women and 1,030 men, and 14 months later at endline with 1,046 women and 1,045 men. Using sex-stratified models, we assessed balance across intervention and comparison groups on background characteristics using Pearson's chi-square tests of independence; performed bivariate tests of independence to assess differences between baseline to endline on intermediate outcomes and primary FP outcomes; used logistic regression to examine the effect of intervention components on intermediate and primary FP outcomes.

Results

Statistically significant improvements in primary outcomes: women's intentions to use modern contraception, achieve met need, and reduce perceived met need. The fourth primary outcome, actual use, showed substantial gains, although not statistically significant. Men's achievement of met FP need and reduced perceived met need were also statistically significant. Assessing intermediate outcomes at individual, couple, normative-network levels, TJ led to statistically significant increases in couple and network communication on fertility desires and family planning use and self-efficacy and confidence to access services. Both women and men showed significant shifts in the acceptability of discussing FP in public. Results for other indicators of norms change were inconsistent.

Conclusions

An easy-to-implement, short-duration, gender-equitable social network intervention with a limited set of network actors, TJ effectively decreases social and normative barriers preventing women and men from seeking and using FP services. Results support the broader use of innovative social and behaviour change strategies that diffuse family planning ideas through social networks, diminish normative and communication barriers, and catalyse modern family planning use.

Supplementary Information

The online version contains supplementary material available at 10.1186/s12889-022-12681-4.

In many places with relatively low family planning use, insufficient program attention is paid to socio-normative barriers that influence need and method use. TJ catalyses women and men's social networks to spread new ideas and break communication and other social barriers that prevent women and men with unmet needs – people who wish to space their next birth but are not using effective family planning methods - from acting on their desires. A rigorous evaluation of the approach in rural Benin showed after only 14 months, TJ led to statistically significant improvements in intention to use contraception and met need. While showing substantial gains, women's use of contraception was not statistically significant.

TJ increased women's and men's partner and network communication on fertility desires and family planning use and individual self-efficacy and confidence to act on intentions to address unmet need. The network influence on family planning use was equally significant. TJ led to new ideas within communities/social networks, including the perception that one's social networks approve of FP. Women and men who report that their network approves of FP were significantly more likely to discuss method use with their partners and seek services. TJ led to new perceptions that one's networks support FP.

TJ represents an underused strategy for social and behaviour change. The social network approach encourages addressing the often-neglected social factors that stop women and men from acting on their desires to space births and use modern family planning methods.

Fostering gender equality and reproductive and sexual health among adolescents: results from a quasi-experimental study in Northern Uganda

OBJECTIVE

To assess the impact of the Gender Roles, Equality and Transformations (GREAT) intervention: a narrative-based, resource-light, life-stage tailored intervention package designed to promote gender-equitable attitudes and behaviours, and improve sexual and reproductive health (SRH) and gender-based violence (GBV) outcomes among adolescents and their communities.

DESIGN

Repeated cross-sectional evaluation study, using propensity score matching combined with difference-in-difference estimation.

SETTING

Two postconflict communities in Lira and Amuru districts in Northern Uganda.

PARTICIPANTS

Male and female unmarried adolescents (10-14 years, 15-19 years), married adolescents (15-19 years) and adults (over the age of 19 years) were selected using a stratified, two-stage cluster sample of primary and secondary schools and households (baseline: n=2464, endline: n=2449).

PRIMARY OUTCOME MEASURES

Inequitable gender attitudes and behaviours; GBV; and SRH knowledge and behaviours.

RESULTS

Statistically significant intervention effects were seen across all three outcomes-gender equity, GBV and SRH-among older and newly married adolescents and adults. Among older adolescents, intervention effects include shifts on: inequitable gender attitudes scale score: -4.2 points ((95% CI -7.1 to -1.4), p<0.05); Inequitable household roles scale score: -11.8 ((95% CI -15.6to -7.9), p<0.05); Inequitable attitudes towards GBV scale: -1.9 ((95% CI -5.0 to -0.2), p<0.05); per cent of boys who sexually assaulted a girl in past 3 months: -7.7 ((95% CI -13.1 to -2.3), p<0.05); inequitable SRH attitudes scale: -10.1 ((95% CI -12.9 to -7.3), p<0.05). Among married adolescents, intervention effects include shifts on: Inequitable household roles scale score: -6.5 ((95% CI -10.8 to -2.2), p<0.05); inequitable attitudes towards GBV scale: -4.7 ((95% CI -9.8 to -0.3), p<0.05); per cent who reacted violently to their partner: -15.7 ((95% CI -27.1 to -4.4), p<0.05); inequitable SRH attitudes scale: -12.9 ((95% CI -17.3 to -8.5), p<0.05).

CONCLUSION

The GREAT intervention model demonstrates the promise of a resource-light, life-stage tailored programme that employs culturally appropriate, participatory and narrative-based techniques to advance gender equity and adolescent health. This type of programming contributes towards reductions in GBV and improved adolescent SRH outcomes.

Relationship between adolescent friendship networks and contraceptive use and unintended pregnancies in early adulthood in the United States

OBJECTIVE

To examine the relationship between reproductive attitude of friends during adolescence, and unintended pregnancy outcomes and contraceptive non-use during early adulthood.

STUDY DESIGN

We used longitudinal data from the National Longitudinal Study of Adolescent to Adult Health (n=1866). Adolescent friendship network structures were constructed from the first wave of data to assess reproductive attitudes of friends, measured via three sub-scales: attitude towards contraceptive use, attitude towards sex in adolescence, and attitude towards pregnancy in adolescence. We then used multi-level logistic regression to examine the relationship of friends' reproductive attitudes in adolescence with unintended pregnancy and contraceptive non-use in adulthood.

RESULTS

Around one-third of the sample experienced at least one unintended pregnancy, and 12% reported contraceptive non-use. Being friends with individuals who are not accepting of adolescent pregnancy reduced the likelihood of an unintended pregnancy in young adulthood (Adjusted Odds Ratios [aOR]: 0.79; 95% CI: 0.67-0.94); this association varied by sex, being significant only for females (aOR:0.75; 95% CI: 0.58 - 0.96). Additionally, friends' acceptability of adolescent sex increased the odds of contraceptive use in later life. Individuals with friends who held negative attitude toward contraceptive use during adolescence were more likely to be non-users in later life (aOR:1.37; 95% CI: 1.03-1.81).

CONCLUSIONS

Our results suggest a relationship between adolescent social networks and reproductive health outcomes in young adulthood, highlighting the importance of friendship networks for young individuals' reproductive well-being.

IMPLICATIONS

Attitudes held by adolescent friends regarding contraceptive use, adolescent sex, and adolescent pregnancy have significant, and distinct associations with an individuals' later-life reproductive health outcomes. Future research should consider evaluation of social network-based sexual and reproductive health interventions aimed at adolescents.

Freedom of Movement and Adolescent Sexual Violence in India

This study assesses associations between freedom of movement and sexual violence, both in marriage and outside of marriage, among a representative sample of adolescents in India. We analyzed data from girls aged 15 to 19 years (n = 9,593) taken from India's nationally representative National Family Health Survey 2015-2016. We defined freedom of movement using three items on whether girls could go unaccompanied to specified locations; we summated responses and categorized them as restricted, or unrestricted. We used multivariable regression to assess associations between restricted movement and nonmarital violence, and with marital sexual violence among ever-married girls. Results show that only 2% of girls reported nonmarital sexual violence, among married and unmarried girls; 6% of married girls reported marital sexual violence. Most girls (78%) reported some restriction in movement. Restricted movement was negatively associated with nonmarital sexual violence (adjusted odds ratio [AOR] = 0.52, 95% confidence interval [CI] = [0.31, 0.87], p = .01) but positively associated with marital sexual violence (AOR = 3.87, 95% CI = [1.82, 8.25], p < .001). Further analyses highlight that the observed association with nonmarital sexual violence was specific to urban and not rural girls. These findings reveal that approximately one in 30 adolescent girls in India has been a victim of sexual violence. Restricted movement is associated with lower risk for nonmarital sexual violence for urban adolescent girls, possibly due to lower exposure opportunity. Married girls with restricted movement have higher odds of marital sexual violence, possibly because these are both forms of control used by abusive husbands. Freedom of movement is a human right that should not place girls at greater risk for nonmarital violence or be used as a means of control by abusive spouses. Social change is needed to secure girls' safety in India.

Community engagement for health system resilience: evidence from Liberia's Ebola epidemic

The importance of community engagement (CE) for health system resilience is established in theoretical and empirical literature. The practical dimensions of how to operationalize theory and implement its principles have been less explored, especially within low-resource crisis settings. It is therefore unclear how CE is drawn upon and how, if at all, it facilitates health system resilience in times of health system crises. To address this critical gap, we adapt and apply existing theoretical CE frameworks to analyse qualitative data from 92 in-depth interviews and 16 focus group discussions collected with health system stakeholders in Liberia in the aftermath of the 2014-15 Ebola outbreak. Health system stakeholders indicated that CE was a crucial contributing factor in addressing the Ebola epidemic in Liberia. Multiple forms of CE were used during the outbreak; however, only some forms were perceived as meaningful, such as the formation of community-based surveillance teams. To achieve meaningful CE, participants recommended that communities be treated as active participants in-as opposed to passive recipients of-health response efforts and that communication platforms for CE be established ahead of a crisis. Participant responses highlight that meaningful CE led to improved communication with and increased trust in health authorities and programming. This facilitated health system response efforts, leading to a fortuitous cycle of increased trust, improved communication and continued meaningful CE-all necessary conditions for health system resilience. This study refines our understanding of CE and demonstrates the ways in which meaningful CE and trust work together in mutually reinforcing and beneficial ways. These findings provide empirical evidence on which to base policies and programmes aimed at improving health system resilience in low-resource settings to more effectively respond to health system crises.

Cross-classified multilevel models (CCMM) in health research: A systematic review of published empirical studies and recommendations for best practices

Recognizing that health outcomes are influenced by and occur within multiple social and physical contexts, researchers have used multilevel modeling techniques for decades to analyze hierarchical or nested data. Cross-Classified Multilevel Models (CCMM) are a statistical technique proposed in the 1990s that extend standard multilevel modeling and enable the simultaneous analysis of non-nested multilevel data. Though use of CCMM in empirical health studies has become increasingly popular, there has not yet been a review summarizing how CCMM are used in the health literature. To address this gap, we performed a scoping review of empirical health studies using CCMM to: (a) evaluate the extent to which this statistical approach has been adopted; (b) assess the rationale and procedures for using CCMM; and (c) provide concrete recommendations for the future use of CCMM. We identified 118 CCMM papers published in English-language literature between 1994 and 2018. Our results reveal a steady growth in empirical health studies using CCMM to address a wide variety of health outcomes in clustered non-hierarchical data. Health researchers use CCMM primarily for five reasons: (1) to statistically account for non-independence in clustered data structures; out of substantive interest in the variance explained by (2) concurrent contexts, (3) contexts over time, and (4) age-period-cohort effects; and (5) to apply CCMM alongside other techniques within a joint model. We conclude by proposing a set of recommendations for use of CCMM with the aim of improved clarity and standardization of reporting in future research using this statistical approach.

Time from COVID-19 shutdown, gender-based violence exposure, and mental health outcomes among a state representative sample of California residents

BACKGROUND

There is increasing evidence of the negative impact of the COVID-19 pandemic and resultant shutdowns on mental health. This issue may be of particular concern to those affected by intimate partner violence (IPV) and sexual violence.

METHODS

We conducted a cross-sectional analysis using data from a California state-representative online survey conducted in the two weeks following the state stay-at-home order, enacted March 19, 2020 (unweighted N = 2081). We conducted a series of multivariate multinomial logistic regressions to assess the associations between a) time since stay-at-home order and b) partner and sexual violence exposure ever with our outcomes of interest: depression and/or anxiety symptoms in the past two weeks. Covariates included demographics and social support.

FINDINGS

Nearly one in five (19•7%) respondents reported moderate or severe mental health symptoms in the past two weeks; 15•5% had a history of IPV and 10•1% had a history of sexual violence. In models adjusting for gender, partner and sexual violence history, and other demographics, time was significantly associated with greater mental health symptom severity, as were IPV and sexual violence. When we additionally adjusted for current social support, effects of time were lost and effects related to violence were slightly attenuated.

INTERPRETATION

Time under shutdown is associated with higher odds of depression and anxiety symptoms, and may be worse for those with a history of IPV. However, those with greater social support appear to have better capacity to withstand the mental health impacts of the pandemic. Social support programs, inclusive of those available virtually, may offer an important opportunity to help address increased mental health concerns we are seeing under the pandemic.

Increased vaccine tolerability and protection via NF-κB modulation

Improving adjuvant responses is a promising pathway to develop vaccines against some pathogens (e.g., HIV or dengue). One challenge in adjuvant development is modulating the inflammatory response, which can cause excess side effects, while maintaining immune activation and protection. No approved adjuvants yet have the capability to independently modulate inflammation and protection. Here, we demonstrate a method to limit inflammation while retaining and often increasing the protective responses. To accomplish this goal, we combined a partial selective nuclear factor kappa B (NF-kB) inhibitor with several current adjuvants. The resulting vaccines reduce systemic inflammation and boost protective responses. In an influenza challenge model, we demonstrate that this approach enhances protection. This method was tested across a broad range of adjuvants and antigens. We anticipate these studies will lead to an alternative approach to vaccine formulation design that may prove broadly applicable to a wide range of adjuvants and vaccines.

Social normative and social network factors associated with adolescent pregnancy: a cross-sectional study of 176 villages in rural Honduras

Background

Adolescent pregnancy and childbirth are common throughout Central America. While gendered beliefs promoting motherhood are a known risk factor, their association with adolescent childbirth within the social networks of Central American communities is unknown.

Methods

This was a cross-sectional study looking at adolescent childbirth amongst women ages 15-20 years (N = 2990) in rural Honduras, using reproductive health data on all individuals ≥15 years of age (N = 24 937 of 31 300 population) including social network contacts, all of whom were interviewed as part of the study. The outcome, adolescent childbirth, was defined as having had a child < age 20 years. Predictors included whether a woman’s social contact had an adolescent childbirth and the social contact’s reported perception of community support for adolescent childbirth.

Results

While girls who identified a father in the village as a social contact had a lower likelihood of adolescent childbirth regardless of whether or not they reported being in a partnership, this finding did not hold for girls who identified mothers. There was an association between a social contact’s report of norms supporting adolescent childbirth and a girl’s risk of adolescent childbirth; however, village-level aggregate norms attenuated that relationship. Independent significant associations were found between a girl’s risk of adolescent childbirth and both a social contact’s adolescent childbirth and the village proportion of women who had had an adolescent childbirth. The association between social contacts’ adolescent childbirth and a girl’s risk of adolescent childbirth across relationships was more robust for stronger relationships and when the social contact was closer in age to the girl.

Conclusions

If, as this evidence suggests, a strong driver of adolescent childbirth is the frequency of the occurrence of adolescent childbirth both within the greater community and within a girl’s proximal social network, the challenge for intervention strategies is to encourage norms that prevent adolescent childbirth without stigmatising those who have had an adolescent childbirth. Programmatic efforts to counter prevailing norms that limit a woman’s role to motherhood, and that support and encourage strong norms for girls’ education may play an important role in addressing this situation.

How are the domains of women's inclusion, justice, and security associated with maternal and infant mortality across countries? Insights from the Women, Peace, and Security Index

Women's autonomy and empowerment in their homes, communities, and societies at large have been shown, through many direct and indirect pathways, to be associated with maternal and infant health. A novel global measure—the Women, Peace, and Security (WPS) Index—that bridges insights from gender and development indices with those from peace and security has recently been developed to capture the constructs of women's inclusion, justice, and security, using indicators and targets in the Sustainable Development Goals. This paper adds to the growing literature about the importance of gender inequality to key mortality outcomes for women and children by investigating the associations between nations' WPS Index scores and maternal mortality ratios and infant mortality rates. We use a range of international databases to obtain country-level data from 144 nations on health, demographic, income, and gender equality indicators. The aim is to highlight the role of women's inclusion, justice, and security in explaining national rates of maternal and infant mortality. Fully adjusted Poisson regression models indicate that a one point (0.01) increase on the WPS Index score is associated with a 2.0% reduction in the number of maternal deaths and a 2.3% reduction in the number of infant deaths. For a country such as Sierra Leone, with a maternal mortality ratio of 1360 maternal deaths per 100,000 live births, a one point improvement in the WPS Index would correspond to a maternal mortality ratio of 1,332, or 28 fewer deaths per 100,000 births. These associations are ecological and apply to the average level of mortality at the country level rather than the likelihood or risk faced at the individual level. Although we cannot claim causality for the observed relations in the cross-country regressions, the findings and recurring patterns are both suggestive and encouraging about the potential contributions of women's inclusion, justice, and security to maternal and infant mortality.

•

The Women, Peace, and Security (WPS) Index is a novel composite index, developed in 2019.

•

The index measures women’s inclusion (economic, political, social); justice; and security (at home and in society).

•

Using data from 144 nations, we find a significant relationship between the WPS Index and maternal and infant mortality.

•

The inclusion and security aspects of the WPS Index are especially significant.

Gender Perspectives on Social Norms Surrounding Teen Pregnancy: A Thematic Analysis of Social Media Data

BACKGROUND

Social concern with teen pregnancy emerged in the 1970s, and today's popular and professional health literature continues to draw on social norms that view teen pregnancy as a problem-for the teen mother, her baby, and society. It is unclear, however, how adolescents directly affected by teen pregnancy draw upon social norms against teen pregnancy in their own lives, whether the norms operate differently for girls and boys, and how these social norms affect pregnant or parenting adolescents.

OBJECTIVE

This research aims to examine whether and how US adolescents use, interpret, and experience social norms against teen pregnancy.

METHODS

Online ethnographic methods were used for the analysis of peer-to-peer exchanges from an online social network site designed for adolescents. Data were collected between March 2010 and February 2015 (n=1662). Thematic analysis was conducted using NVivo software.

RESULTS

American adolescents in this online platform draw on dominant social norms against teen pregnancy to provide rationales for why pregnancy in adolescence is wrong or should be avoided. Rationales range from potential socioeconomic harms to life-course rationales that view adolescence as a special, carefree period in life. Despite joint contributions from males and females to a pregnancy, it is primarily females who report pregnancy-related concerns, including experiences of bullying, social isolation, and fear.

CONCLUSIONS

Peer exchange in this online forum indicates that American adolescents reproduce prevailing US social norms of viewing teen pregnancy as a social problem. These norms intersect with the norms of age, gender, and female sexuality. Female adolescents who transgress these norms experience bullying, shame, and stigma. Health professionals must ensure that strategies designed to prevent unintended adolescent pregnancy do not simultaneously create hardship and stigma in the lives of young women who are pregnant and parent their children.

Adolescent Sexual Initiation: A Cross-Classified Multilevel Analysis of Peer Group-, School-, and Neighborhood-Level Influences

PURPOSE

This study examines the simultaneous roles of neighborhood, school, and peer group contexts on variation in age of U.S. adolescent sexual initiation (coitarche). All three contexts have been shown to be important determinants of adolescent sexual and reproductive health outcomes but are typically examined separately, leaving a large gap in our understanding of their relative and joint importance. Furthermore, little is known about whether these contexts matter differently for boys and girls.

METHODS

Using sociocentric network data from the National Longitudinal Study of Adolescent to Adult Health, we combine gender-stratified analyses, social network community detection (to identify teens' social cliques), and cross-classified multilevel modeling to simultaneously analyze gender, neighborhood, school, and peer group effects. These results are compared against results from traditional multilevel models (MLMs), which analyze the contexts individually.

RESULTS

Evaluated separately in MLM, peer groups accounted for 6.79% of the total variation in coitarche, schools for 3.56%, and neighborhoods for 4.11%. Under simultaneous cross-classified multilevel modeling analysis, a different story emerges: peer groups and schools accounted for 3.66% and 3.19% of the total variation in coitarche, respectively, whereas neighborhood explained only 1.16% of the total variation. Stratified analyses indicate that gender modifies these associations.

CONCLUSIONS

Results demonstrate that omitting any one of these contexts may lead to an overestimation of the importance of contexts included in models. When modeled simultaneously with neighborhoods, our findings suggest that peer groups and schools are meaningful contributing contexts to the variance in sexual initiation, and that these contexts matter differently for boys and girls.

Head Start Staff Reactions to a Novel Tobacco Intervention: A Qualitative Analysis

OBJECTIVES

As tobacco use becomes increasingly concentrated in communities of low socio-economic position (SEP), scalable cessation interventions are needed. Head Start programs offer one setting in which a family-focused intervention can be implemented in low SEP communities. We assessed the experiences of Head Start (HS) staff who received training in a pilot motivational interviewing (MI) tobacco intervention, to improve future feasibility.

METHODS

Focus group interviews were conducted with HS staff to assess their reactions to MI training and their use of MI in their work with families. Transcripts were analyzed using thematic analysis and a 4-step approach informed by grounded theory.

RESULTS

HS staff reported advantages of MI beyond its use as a tobacco intervention, despite systematic barriers to broad implementation. Facilitators of MI use included enhanced engagement with families, and opportunities for professional development. Barriers to MI use included limited institutional support and low priority for a tobacco intervention among families with pressing social and financial concerns.

CONCLUSIONS

HS Staff voiced support for broader training in MI interventions in HS programs. System-wide standards to ensure adequate training and support for an MI tobacco intervention were identified as priorities.

Self-efficacy of children and adolescents: a meta-analysis

The current study analyzed empirical work examining the relationship of self-efficacy to subsequent behavior in children under the age of 16. Applying meta-analytic techniques to 26 studies (N = 1692) published in the psychological literature between 1977 and 1989 resulted in a mean effect size (r) of .334 across studies.
