The belief that contraceptive use causes infertility has been documented across sub-Saharan Africa, but its quantitative association with actual contraceptive use has not been examined. We collected and analyzed sociocentric network data covering 74 percent of the population in two villages in rural Kenya. We asked respondents to nominate people from their village (their network), and then we matched their network (alters) to the individual participant (ego) to understand how their beliefs and behaviors differ. We asked about contraceptive use and level of agreement with a statement about contraceptive use causing infertility. We calculated the average nominated network contraceptive use score and the average nominated network belief score. Holding the individual belief that contraceptive use causes infertility was associated with lower odds of using contraceptive (AOR = 0.82, p = < 0.01); however, when one's own nominated network connections held this belief, the odds of using contraceptive were even lower (AOR = 0.75, p <0.01). Our findings show that this belief is associated with lower odds of contraceptive use and highlights the role that other people in one's network play in reinforcing it. Sexual and reproductive health programs should address this misperception at the individual and social network level.

In less egalitarian countries such as Pakistan, reproductive behaviors are gendered, with couples often disagreeing about their fertility goals. However, the dramatic changes in women's empowerment and messaging around reproductive behaviors in Pakistan in recent years may have affected how women's own characteristics and their concordance with their spouse on fertility goals are linked to contraception. Using matched couple data from two cycles of the Pakistan Demographic Health Survey (1990-1991 and 2017-2018), this paper examines the relative influence of husbands' and wives' fertility preferences, as well as women's education, on contraceptive use using linear probability models. Disagreement between couples declined modestly, by about four percentage points, over time. When disagreement about future fertility intentions occurs, wife's fertility preferences are more strongly related to contraceptive behavior, and this association has not changed over time. Although contraceptive use is positively associated with education, the link between women's education and contraceptive use has weakened over time due to increased use among uneducated women. Pakistani women's own fertility preferences are reflected in their contraceptive behavior, and contraceptive use is increasing among all women, even less educated women. Diffusion processes are likely at play, though more work is needed to identify these processes and potential barriers to contraceptive use.

Between 2016 and 2018, we observe in Uruguay a steep decline of almost 20 percent in the number of total births, leading to the collapse of the adolescent fertility rate after decades of relative stagnation. We estimate the quantitative contribution on birth rates, especially teen births, of a policy of expanded availability of subdermal contraceptive implants. We exploit the expansion schedule of a large-scale policy of free-of-charge access to subdermal implants in the country's public health system through an event study to capture causal effects. We use detailed birth administrative records for the past 20 years. We document an average reduction of 3 percent in the birth rate in public health facilities across the two years after the policy was implemented in each department. These reductions were notably higher among teens and first births. Although changes in women's fertility decisions are a multicausal phenomenon, we claim that the expanded availability of subdermal contraceptive implants accounted for one-third of the teen and young women's birth collapse.

The global family planning community has made significant progress towards enabling 120 million more women and girls to use contraceptives by 2020, though we enter the decade ahead with a long road yet to travel. While investment in strong health systems and supply chains is still needed, the supply-driven approach dominant in family planning fails to address the individual, relational, and social barriers faced by women and couples in achieving their reproductive intentions and desired family size. Overcoming these barriers will require a better understanding of behavioral drivers and the social environment in which family planning decisions are made, and an increased investment in the proven, yet underutilized, approach of social and behavior change (SBC). We make the case that a more intentional focus on the science of human behavior in family planning can help advance the achievement of global, regional, and national goals while also calling for strategic and sustained investment that reflects the critical importance and proven impact of SBC approaches.

Infertility and unintended pregnancy are dual burdens in Malawi, where 41% of pregnancies are unintended and approximately 20% of people report infertility. Although preventing unintended pregnancy has been a focus in public health, infertility has rarely been explored as a factor that may be associated with contraceptive use. Using cross-sectional survey data (2017-2018; N = 749), we report on the prevalence of and sociodemographic characteristics associated with infertility and certainty of becoming pregnant among women in Malawi. We conducted multivariable logistic regressions examining the relationship between infertility, certainty of becoming pregnant, and contraceptive use. Approximately 16% of women experienced infertility, and three-quarters (78%) were certain they could become pregnant within one year. Women who experienced infertility had lower odds of contraceptive use than women who did not (Adjusted Odds Ratio [AOR]: 0.56; 95% Conficence Interval [CI]: 0.39-0.83). Women who said there was "no chance" or they were "unlikely" to become pregnant also had lower odds of contraceptive use compared to women who were certain they would become pregnant (AOR: 0.30; 95% CI: 0.10-0.92). Our findings indicate that experiences and perceptions surrounding fertility are associated with contraceptive use, underscoring their importance in understanding how people manage their fertility to reach their reproductive goals.

Population-based indicators of the coverage of key elements of high-quality family planning services are tracked via household surveys with female respondents, yet little work has been done to establish their validity. We take advantage of existing data sets from Cambodia and Kenya to compare women's responses at exit interviews following a health facility visit against the observations of a trained third-party observer during the visit. The results, which treat the observations as the reference standard, show that indicators that measure contraceptive methods received are accurately reported while indicators of whether the woman received her preferred method and whether information was "discussed" or "explained" during counseling are less reliably reported. Studies designed explicitly to assess the validity of family planning questions in household surveys, especially questions in large survey programs critical for monitoring demographic trends and programmatic coverage, are needed.

Previous research on sex ratio at birth (SRB) in India has largely relied on macro-analysis of census data that do not contain the breadth of factors needed to explain patterns in SRB. Additionally, no previous research has examined the differentiation of factors associated with SRB across birth orders, a key determinant in societies affected by son preference. This study aims to fill these gaps using micro-data related to 553,461 births occurring between 2005 and 2016 collected as part of the 2015-2016 National Family Health Survey. Analyses used multivariable logistic regressions stratified by birth order to examine associations with SRB at the national level. The SRB at birth order 1 was outside the biological normal limit, and generally increased with birth order. First births in households with wealth in the middle and richest quintiles, with mothers who desired a higher ideal number of sons than daughters, and in lower fertility communities had a higher probability of being male. Most SRB correlates were visible at birth orders 3 or higher. Programs and policies designed to address India's male-skewed SRB must consider the diverse factors that influence SRB, particularly for higher order births.

Despite improvements in family planning (FP) knowledge and services in West Africa, unmet need for FP continues to grow. Many programs apply a demographically and biologically driven definition of unmet need, overlooking the complex social environment in which fertility and FP decisions are made. This longitudinal, qualitative cohort study captures the changing nature of FP need, attitudes and behaviors, taking into account life context to inform understanding of the complex behavior change process. Purposively sampled, 25 women and 25 men participated in three rounds of in-depth interviews over 18 months. Analyses used a social network influence lens. Findings suggest alignment of six foundational building blocks operating at individual, couple, services, and social levels is essential to meet FP need. If one block is weak, a person may not achieve met need. Women and men commonly follow five pathways as they seek to fulfill their FP need. Some pathways achieve met need (determined users, quick converters), some do not (side effect avoiders), and some do not lead to consistent FP outcomes (male-priority decision makers, gender-egalitarian decision makers). Findings clarify the role of social determinants of FP and offer insight into program approaches informed by user typologies and return on program investments.

Financial barriers may restrict women's ability to use their preferred contraceptive methods, especially long-acting reversible contraceptives (LARC). Providing free access to a broad contraceptive method mix, including both LARC and short-acting reversible contraceptives (SARC), may increase contraceptive use, meet women's various fertility needs, and increase their agency in contraceptive decisions. Linking facility and individual data from eight countries in sub-Saharan Africa, we use a propensity score approach combined with machine learning techniques to examine how free access to a broad contraceptive method mix affects women's contraceptive choice. Free access to both LARC and SARC was associated with an increase of 3.2 percentage points (95 percent confidence interval: 0.006, 0.058) in the likelihood of contraceptive use, driven by greater use of SARC. Among contraceptive users, free access did not prompt women to switch to LARC and had no effect on contraceptive decision-making. The price effects were larger among older and more educated women, but free access was associated with lower contraceptive use among adolescents. While free access to contraceptives is associated with a modest increase in contraceptive use for some women, removing user fees alone does not address all barriers women face, especially for the most vulnerable groups of women.
