Social transmission and the spread of modern contraception in rural Ethiopia.

ABSTRACT: Socio-economic development has proven to be insufficient to explain the time and pace of the human demographic transition. Shifts to low fertility norms have thus been thought to result from social diffusion, yet to date, micro-level studies are limited and are often unable to disentangle the effect of social transmission from that of extrinsic factors. We used data which included the first ever use of modern contraception among a population of over 900 women in four villages in rural Ethiopia, where contraceptive prevalence is still low (<20%). We investigated whether the time of adoption of modern contraception is predicted by (i) the proportion of ever-users/non ever-users within both women and their husbands' friendships networks and (ii) the geographic distance to contraceptive ever-users. Using a model comparison approach, we found that individual socio-demographic characteristics (e.g. parity, education) and a religious norm are the most likely explanatory factors of temporal and spatial patterns of contraceptive uptake, while the role of person-to-person contact through either friendship or spatial networks remains marginal. Our study has broad implications for understanding the processes that initiate transitions to low fertility and the uptake of birth control technologies in the developing world.

Project description:BackgroundContraceptive use is the best and most cost-effective strategy to reduce feto-maternal adverse effects of short birth intervals. More than two-thirds of women in developing countries who do not want to conceive are not using contraception methods. Although there were various primary studies in different parts of the country, there is no nationally representative evidence on postpartum modern contraception utilization and its determinants in Ethiopia.ObjectiveThis review was aimed to determine the best available pieces of evidence to pool the magnitude of postpartum modern contraception utilization and find out its determinants.MethodsPublished studies were extensively searched by using electronic databases and unpublished studies were identified from the digital library. All observational studies conducted on the magnitude of postpartum modern contraception utilization and its determinants in Ethiopia were included. Data were extracted on the Microsoft Excel spreadsheet and analyzed using STATA 14.1 version. A random-effects model was used to estimate the pooled magnitude of postpartum modern contraception utilization with a 95% confidence interval (CI). Inverse variance (I2) was used to identify the presence of heterogeneity and forest plot was used to estimate the pooled magnitude of postpartum contraception utilization. The presence of publication bias was assessed by funnel plots and Egger's statistical tests. Sub-group analysis was computed to minimize underlying heterogeneity.FindingsIn this review, 19 primary studies were included. The pooled magnitude of postpartum modern contraception utilization in Ethiopia was 45.79% (95%CI 36.45%, 55.13%). The review found that having more than four Antenatal care visits(ANC), having postnatal care visit (PNC), having a formal education, history of family planning use, history of counseling on family planning, and having greater than four alive children as significant determinants of postpartum modern contraception utilization.ConclusionThe magnitude of postpartum modern contraception utilization in Ethiopia was low. ANC visit, PNC visit, maternal educational status, history of previous family planning use, counseling on family planning, and number of alive children were found to be significant determinants of postpartum modern contraception utilization. Therefore, strengthening focused ANC and PNC services to encourage women in utilizing modern contraception during the postnatal period is needed.

Project description:ObjectivesNew Mexico is a large rural state with high rates of unintended pregnancy and limited access to contraception. In 2017, the New Mexico Pharmacist Prescriptive Authority Act was amended to allow pharmacists to prescribe hormonal contraception. We explored pharmacist perspectives on prescribing hormonal contraceptives, including perceived barriers and facilitators to implementation in rural New Mexico and opinions on over-the-counter (OTC) access, and prescribing and inserting subdermal contraceptive implants.MethodsThis qualitative study recruited rural pharmacists using contact information from the New Mexico Board of Pharmacy and at a state-level pharmacist conference. We conducted semistructured telephone interviews with pharmacists focusing on benefits and concerns about prescribing hormonal contraception, resources required, perspectives on OTC access, and interest in prescribing and placing contraceptive implants. Deidentified transcribed interviews were analyzed by 2 independent coders for emerging themes.ResultsFrom November 2017 to January 2018, we recruited 25 rural pharmacists and conducted 21 interviews. The majority of participants were male (71%), aged over 60 years (43%), and in practice for over 20 years (52%). Interviewees were mostly positive about prescribing hormonal contraception citing community benefits. The top 3 perceived barriers were training needs, reimbursement, and liability. The top 3 facilitators were the availability of private areas within pharmacies, pharmacists' role as knowledgeable health care team members, and pharmacist accessibility without appointments. Most pharmacists did not support OTC access to hormonal contraception, and over half were interested in certification to prescribe and place subdermal contraceptive implants.ConclusionNew Mexico pharmacists identified community benefits of pharmacy access to hormonal contraception and were interested in training. Several barriers must be addressed to realize the potential of this practice expansion.

Project description:BackgroundQuality surveillance data used to build tuberculosis (TB) transmission models are frequently unavailable and may overlook community intrinsic dynamics that impact TB transmission. Social network analysis (SNA) generates data on hyperlocal social-demographic structures that contribute to disease transmission.MethodsWe collected social contact data in five villages and built SNA-informed village-specific stochastic TB transmission models in remote Madagascar. A name-generator approach was used to elicit individual contact networks. Recruitment included confirmed TB patients, followed by snowball sampling of named contacts. Egocentric network data were aggregated into village-level networks. Network- and individual-level characteristics determining contact formation and structure were identified by fitting an exponential random graph model (ERGM), which formed the basis of the contact structure and model dynamics. Models were calibrated and used to evaluate WHO-recommended interventions and community resiliency to foreign TB introduction.ResultsInter- and intra-village SNA showed variable degrees of interconnectivity, with transitivity (individual clustering) values of 0.16, 0.29, and 0.43. Active case finding and treatment yielded 67%-79% reduction in active TB disease prevalence and a 75% reduction in TB mortality in all village networks. Following hypothetical TB elimination and without specific interventions, networks A and B showed resilience to both active and latent TB reintroduction, while Network C, the village network with the highest transitivity, lacked resiliency to reintroduction and generated a TB prevalence of 2% and a TB mortality rate of 7.3% after introduction of one new contagious infection post hypothetical elimination.ConclusionIn remote Madagascar, SNA-informed models suggest that WHO-recommended interventions reduce TB disease (active TB) prevalence and mortality while TB infection (latent TB) burden remains high. Communities' resiliency to TB introduction decreases as their interconnectivity increases. "Top down" population level TB models would most likely miss this difference between small communities. SNA bridges large-scale population-based and hyper focused community-level TB modeling.
