Benefits of chest wall mobilization on respiratory efficiency and functional exercise capacity in people with severe chronic obstructive pulmonary disease (COPD): A randomized controlled trial.

BACKGROUND: Coexistence of chest wall hypomobility and lung hyperinflation compromises respiratory muscle function and respiratory efficiency in people with severe chronic obstructive pulmonary disease (COPD). This study aimed to investigate the effect of chest wall mobilization on functional exercise capacity, respiratory muscle activity and respiratory muscle tissue oxygen saturation for people with severe COPD. METHODS: Thirty male adults (age: 75 ± 6) diagnosed with severe COPD completed a 6-week programme (twice/week) according to intervention randomization (chest wall mobilization group, CWMG, n = 15; control group, CG, n = 15). Both groups received standardized education and walking exercise, while CWMG also received chest wall and thoracic spine mobilization. Electromyography of the essential and accessory respiratory muscles and tissue oxygen saturation of the intercostal muscle (StO2, measured by near-infrared spectroscopy) during incremental cycle exercise test were measured and compared between the two groups at pre-programme, post-programme and 3-month follow-up. RESULTS: Patients in CWMG demonstrated a significant increase in exercise tolerance from <3 METS to 4-6 METS (p = 0.000) after intervention. A significant decrease in activity of scalene, sternocleidomastoids and intercostal muscle during exercise test (p < 0.01) was found in CWMG, as compared to CG. A significant decrease in StO2 (p < 0.05) and greater decline in the slope of oxygenation dissociation (p = 0.000) were seen in CWMG during exercise test. These positive results were maintained at 3-month follow-up in CWMG. CONCLUSION: Improvements in exercise tolerance, respiratory muscle efficiency and oxygenation extraction ability in CWMG suggest a potential clinical benefit of integrating chest wall and thoracic spine mobilization for rehabilitation of people with severe COPD.

Missed opportunities for family planning counselling among postpartum women in eleven counties in Kenya.

BACKGROUND: Mothers may access medical facilities for their babies and miss opportunities to access family planning (FP) services. This study was undertaken to describe missed opportunities for FP among women within the extended (0-11 months) postpartum period from counties participating in Performance Monitoring and Accountability 2020 (PMA2020) surveys. DESIGN AND SETTING: This study analysed cross-sectional household survey data from 11 counties in Kenya between 2014 and 2018. PMA2020 uses questions extracted from the Demographic and Health survey (DHS) and DHS definitions were used. Multivariable logistic regression was used for inferential statistics with p-value of < 0.05 considered to be significant. PARTICIPANTS: Women aged 15-49 years from the households visited. PRIMARY OUTCOME MEASURE: Missed opportunity for family planning/contraceptives (FP/C) counselling. RESULTS: Of the 34,832 women aged 15-49 years interviewed, 10.9% (3803) and 10.8% (3746) were in the period 0-11 months and 12-23 months postpartum respectively, of whom, 38.8 and 39.6% respectively had their previous pregnancy unintended. Overall, 50.4% of women 0-23 months postpartum had missed opportunities for FP/C counselling. Among women who had contact with health care at the facility, 39.2% of women 0-11 months and 44.7% of women 12-23 months had missed opportunities for FP/C counselling. Less than half of the women 0-11 months postpartum (46.5%) and 64.5% of women 12 - 23 months postpartum were using highly efficacious methods. About 27 and 18% of the women 0-11 months and 12 - 23 months postpartum respectively had unmet need for FP/C. Multivariable analysis showed that being low parity and being from the low wealth quintile significantly increased the odds of missed opportunities for FP/C counselling among women in the extended postpartum period, p < 0.05. CONCLUSIONS: A large proportion of women have missed opportunities for FP/C counselling within 2 years postpartum. Programs should address these missed opportunities.

Is Client Reporting on Contraceptive Use Always Accurate? Measuring Consistency and Change with a Multicountry Study.

The consistency of self-reported contraceptive use over short periods of time is important for understanding measurement reliability. We assess the consistency of and change in contraceptive use using longitudinal data from 9,390 urban female clients interviewed in DR Congo, India, Kenya, Niger, Nigeria, and Burkina Faso. Clients were interviewed in-person at a health facility and four to six months later by phone. We compared reports of contraceptive use at baseline with recall of baseline contraceptive use at follow-up. Agreement between these measures ranged from 59.1 percent in DR Congo to 84.4 percent in India. Change in both contraceptive method type (sterilization, long-acting, short-acting, nonuse) and use status (user, nonuser, discontinuer, adopter, switcher) was assessed comparing baseline to follow-up reports and retrospective versus current reports within the follow-up survey. More change in use was observed with panel reporting than within the cross section. The percent agreement between the two scenarios of change ranged from 64.8 percent in DR Congo to 84.5 percent in India, with cross-site variation. Consistently reported change in use status was highest for nonusers, followed by users, discontinuers, adopters, and switchers. Inconsistency in self-reported contraceptive use, even over four to six months, was nontrivial, indicating that studying measurement reliability of contraceptive use remains important.

A Panel Study of Fertility Preferences and Contraceptive Dynamics in the Presence of Competing Pregnancy Risks in Uganda.

Although many studies have examined the influence of women's fertility preferences on subsequent fertility behavior and the role of contraceptive use intentions on unmet need, very few have explored their concurrent effects on contraceptive use dynamics. This study examines the independent concurrent effects of women's fertility preferences and contraceptive intentions on subsequent adoption and discontinuation, treating pregnancy as a competing risk factor that may alter contraceptive need. The data are derived from a 2018 follow-up survey of a 2014 national sample of 3,800 Ugandan female respondents of childbearing age. The survey included a contraceptive calendar that recorded pregnancy, birth, and contraceptive event episodes, including reasons for discontinuation. We use competing risk regression to estimate the effect of fertility preferences and contraceptive intentions on the cumulative incidence function of contraceptive behaviors, accounting for intervening pregnancy, female background covariates, loss to follow-up, and complex survey design. We find that women's contraceptive intentions significantly increase the rate of contraceptive adoption. After having adopted, women's contraceptive intentions have been realized and do not prolong use. The risk of discontinuation among women who adopted after baseline was significantly higher than for those using at baseline, irrespective of their initial intentions. The effectiveness of the type of contraceptive method chosen significantly lowered discontinuation risk. Fertility preferences were not significantly associated with either time to adoption or discontinuation. The pace of the fertility transition in this sub-Saharan African setting is likely being shaped by reproductive regulation through the intentional use of contraception that enables spacing births.

A sexual and reproductive empowerment framework to explore volitional sex in sub-Saharan Africa.

Volitional sex is central to the sexual health and well-being of women and girls globally. To date, few studies have examined women's empowerment and its application to sexual health outcomes, including volitional sex. The aim of this study was to explore the relevance of a sexual and reproductive empowerment framework to volitional sex across four geographically and culturally diverse contexts in sub-Saharan Africa. Qualitative data were collected between July and August 2017 in four sites: Ethiopia, Nigeria (Anambra and Kano states) and Uganda. A total of 352 women aged 15-49 and 88 men aged 18 and older were interviewed through 120 in-depth interviews and 38 focus group discussions (n = 440 total participants). Results describe the substantial barriers restraining women's sexual choices, particularly norms that stigmatise women's requests for sex, even within marriage. Results further highlight women's internal sexual motivations, particularly related to the enjoyment of sex and the role of sex in strengthening partner relationships. Future empowerment research and measurement should focus not only on sexual constraints, but also integrate internal motivations, in order to fully understand the factors that shape women's sexual health outcomes.

"You better use the safer one leave this one": the role of health providers in women's pursuit of their preferred family planning methods.

BACKGROUND: Universal access to quality sexual and reproductive health (SRH) services is pivotal to ensuring gender equality. In high-income countries, patient-provider interactions have been shown to shape women's decisions about contraception, with poor exchanges decreasing method uptake and satisfaction. While significant progress has been made to increase women's access to SRH services, in low- and middle-income countries, little is known about the quality of family planning patient-provider interactions. The primary objective of this analysis was to explore the role of health care providers in women's family planning decision-making in Ethiopia. METHODS: From July to August 2017, 10 focus group discussions (n = 80) and 30 in-depth interviews were conducted with women aged 15-49 and men aged 18+ recruited via purposive sampling from urban and rural sites in Ethiopia. Semi-structured interview guides explored women's and girls' empowerment in SRH surrounding sex, childbearing, and contraception. All interviews were conducted in Amharic, audio-recorded, and transcribed verbatim into English. Inductive thematic analysis was used to analyze data. Eleven codes specific to provider services for family planning were reviewed and matrixes creates for synthesis. RESULTS: Three primary themes emerged: the role of providers in women's awareness of and demand for family planning services; selection and uptake of contraceptive methods; and discontinuation and switching of contraceptive methods. Results indicate that health extension workers were central to women's awareness of family planning, and health providers' endorsements were instrumental in decisions to adopt methods. The majority of respondents described positive interactions with providers and appreciated thorough counseling when considering using or switching methods. Some women, however, described health providers directing them toward long-acting methods by communicating inaccurate information or emphasizing disadvantages of short-acting methods. A few women described provider reluctance or resistance to switching methods, especially from implants. CONCLUSIONS: Women shared many narratives about the central roles health providers played in their awareness and decision-making for family planning. Those narratives also included provider bias against women's preferred methods. Further research and program assessments are needed to ascertain the extent to which these biases hinder women's decision-making autonomy in using contraception.

Covert use of contraception in three sub-Saharan African countries: a qualitative exploration of motivations and challenges.

BACKGROUND: The balance between increasing men's participation in family planning and rights-based initiatives favoring women's empowerment is highlighted with the issue of covert use of contraception. While covert use has been documented in low- and middle-income countries as a way for women to obtain contraception in light of partner opposition, little is known about women's decision-making processes, actions, and potential consequences of discreet contraceptive use. We aimed to understand women's choices to use contraception covertly and the challenges they faced in concealing their use across three sub-Saharan African countries. METHODS: Women aged 15-49 and their male partners were purposively sampled from urban and rural sites in Ethiopia, Northern and Southern Nigeria, and Uganda for 120 in-depth interviews and 38 focus group discussions. Semi-structured interviews explored women's and girls' empowerment surrounding sex, childbearing, and contraception. Interviews were conducted in local languages, audio-recorded, and transcribed verbatim into English. Inductive thematic analysis was used to analyze data; covert use codes were reviewed and matrices were created based on themes and sub-themes. RESULTS: Findings comprised three thematic areas: the practice of covert contraceptive use and reasons for using covertly; challenges for women who use contraception covertly; and consequences of disclosure or being discovered. While some women initiated using contraception covertly due to tensions within relationships or to keep peace within the home due to known partner opposition, others did not consider family planning to be a male responsibility. Though covert use was commonly discussed, it was also socially sanctioned, and portrayed as an act of female disobedience that questioned the social order of patriarchy. Further challenges of using covertly included lack of financial and social support, and suspicions surrounding delayed fertility and contraceptive-related side effects. Repercussions comprised increased suspicion, threats, or violence, though some women reported improved couple communication with disclosure. CONCLUSIONS: Results indicate that while covert use of contraception is common, continued covert use is challenging, especially when side effects manifest. Covert use may further suggest women taking independent action, symbolizing some level of empowerment. Results underscore the importance of disentangling unique reasons for covert use and the severity of repercussions of disclosure.

Effect of community health workers' visits on uptake of modern contraception among rural women of reproductive age in Nigeria.

This paper assessed the effect of visits by Community Health Workers (CHW) in the prior 12 months on modern contraceptive use at the time of the survey using a national sample of women residing in rural communities in Nigeria. Cross-sectional data from 5072 rural women ages 15-49 years interviewed in the PMA2020 Survey in 6 states in Nigeria in 2018 were used. Descriptive analysis and generalized linear models were conducted in Stata 15.1 and average marginal effects calculated. Overall prevalence of modern contraceptive use was 14.8% (95% CI: 12.7%, 17.3%), varying from 2.1% in Kano to 22.7% in Nasarawa. Ten percent of women reported that they were visited by a community health worker in the 12-month period preceding the survey, ranging from 2.9% in Kano to 14.6% in Nasarawa. Women visited by a CHW had 50% higher odds of reporting modern contraceptive use, and these visits raised the probability of modern contraceptive use by an average of 6.4 percentage points overall. Local governments in rural Nigeria should invest in training, deploying and supervising CHWs in the provision of modern contraception through home visits to women who may otherwise have limited access to improve use.

Subnational estimation of modern contraceptive prevalence in five sub-Saharan African countries: a Bayesian hierarchical approach.

BACKGROUND: Global monitoring efforts have relied on national estimates of modern contraceptive prevalence rate (mCPR) for many low-income countries. However, most contraceptive delivery programs are implemented by health departments at lower administrative levels, reflecting a persisting gap between the availability of and need for subnational mCPR estimates. METHODS: Using woman-level data from multiple semi-annual national survey rounds conducted between 2013 and 2016 in five sub-Saharan African countries (Burkina Faso, Ethiopia, Ghana, Kenya, and Uganda) by the Performance, Monitoring and Accountability 2020 project, we propose a Bayesian Hierarchical Model with a standard set of covariates and temporally correlated random effects to estimate the level and trend of mCPR for first level administrative divisions in each country. RESULTS: There is considerable narrowing of the uncertainty interval (UI) around the model-based estimates, compared to the estimates directly based on the survey data. We find substantial variations in the estimated subnational mCPRs. Uganda, for example, shows a gain in mCPR of 6.4% (95% UI: 4.5-8.3) based on model estimates of 20.9% (19.6-22.2) in mid-2014 and 27.3% (26.0-28.8) in mid-2016, with change across 10 regions ranging from - 0.6 points in Karamoja to 9.4 points in Central 2 region. The lower bound of the UIs of the change over four rounds was above 0 in 6 regions. Similar upward trends are observed for most regions in the other four countries, and there is noticeable within-country geographic variation. CONCLUSIONS: Reliable subnational estimates of mCPR empower health departments in evidence-based policy making. Despite nationally increasing mCPRs, regional disparities exist within countries suggesting uneven contraceptive access. Raising investments in disadvantaged areas may be warranted to increase equity in access to modern contraceptive methods.

Understanding the meaning of marital relationship quality among couples in peri-urban Ethiopia.

This study explores the meaning of marital relationship quality (MRQ) among couples in peri-urban Ethiopia. We examined the factor structure of MRQ by assessing the reliability and validity of four validated Western scales capturing domains of trust, commitment, satisfaction and communication through exploratory factor analysis. Although most of the items of the original Western scales were relevant for the study population, the domains did not mirror the original Western scales and varied by gender. Interestingly, while the domains of commitment and trust followed the Western scales and were very similar across gender, the third domain, which we labelled conflict differed by gender. For women, items from the constructive communication scale seemed relevant, indicating an interest in resolving conflicts, whereas for men, items from the satisfaction scale appeared more important, indicating a desire to avoid or reduce conflict in their relationships. Our study highlights the usefulness of adapting existing validated scales in a new context after assessing their psychometric properties. Such applications provide opportunities for broadening understanding of fundamental MRQ domains that may universally be shared cross-culturally.

Maternal Risk Exposure and Adult Daughters' Health, Schooling, and Employment: A Constructed Cohort Analysis of 50 Developing Countries.

This study analyzes the relationships between maternal risk factors present at the time of daughters' births-namely, young mother, high parity, and short preceding birth interval-and their subsequent adult developmental, reproductive, and socioeconomic outcomes. Pseudo-cohorts are constructed using female respondent data from 189 cross-sectional rounds of Demographic and Health Surveys conducted in 50 developing countries between 1986 and 2013. Generalized linear models are estimated to test the relationships and calculate cohort-level outcome proportions with the systematic elimination of the three maternal risk factors. The simulation exercise for the full sample of 2,546 pseudo-cohorts shows that the combined elimination of risk exposures is associated with lower mean proportions of adult daughters experiencing child mortality, having a small infant at birth, and having a low body mass index. Among sub-Saharan African cohorts, the estimated changes are larger, particularly for years of schooling. The pseudo-cohort approach can enable longitudinal testing of life course hypotheses using large-scale, standardized, repeated cross-sectional data and with considerable resource efficiency.

Women's fertility desires and contraceptive behavior in three peri-urban communities in sub Saharan Africa.

BACKGROUND: Fertility desires and contraceptive behavior often change over time. This study examined the influence of change in fertility desires on change in modern contraceptive use over time in three peri-urban communities in sub-Saharan Africa. METHODS: This multi-site study includes baseline and follow up data from 3 sites in the Family Health and Wealth Study. Following a census in each site, a probability sample of at least 500 households was obtained. Generalized linear models were employed. RESULTS: Modern contraceptive use increased in Ipetumodu, Nigeria (29.4% to 36.7%), but declined slightly in Sebeta, Ethiopia (66.9% to 61.3%) and Asawase, Ghana (12.6% to 10.8%). Across sites, at baseline and follow up, women who wanted no more children reported more contraceptive use, compared with those who wanted more children, and were more likely to shift to being contraceptive users in Ipetumodu [aOR(95% CI):1.55 (1.07,2.26)]. CONCLUSIONS: Women's fertility desires influenced their contraceptive behavior, although there were cross-site differences. Changing contraceptive demand and program factors will be important to enable peri-urban women to frame and act on their fertility desires.

Access to Contraceptives in Countries With Restrictive Abortion Laws: The Case of Brazil.

We aimed to determine whether current contraceptive use is affected by a history of abortion for women from a country with abortion-restricted laws. This is an analysis of 2006 Brazil Demographic and Health Survey. Nonpregnant women whose first pregnancy occurred in the previous 5 years were selected for this study (n = 2,181). We used propensity score matching to compare current contraceptive use among women with induced or spontaneous abortion and women with no abortion. We found differences in the use, but women with a history of abortion did not report more effective contraceptive than women with no abortion, as we expected.

Contraceptive use following spontaneous and induced abortion and its association with family planning services in primary health care: results from a Brazilian longitudinal study.

BACKGROUND: Although it is well known that post-abortion contraceptive use is high when family planning services are provided following spontaneous or induced abortions, this relationship remains unclear in Brazil and similar settings with restrictive abortion laws. Our study aims to assess whether contraceptive use is associated with access to family planning services in the six-month period post-abortion, in a setting where laws towards abortion are highly restrictive. METHODS: This prospective cohort study recruited 147 women hospitalized for emergency treatment following spontaneous or induced abortion in Brazil. These women were then followed up for six months (761 observations). Women responded to monthly telephone interviews about contraceptive use and the utilization of family planning services (measured by the utilization of medical consultation and receipt of contraceptive counseling). Generalized Estimating Equations were used to analyze the effect of family planning services and other covariates on contraceptive use over the six-month period post-abortion. RESULTS: Women who reported utilization of both medical consultation and contraceptive counseling in the same month had higher odds of reporting contraceptive use during the six-month period post-abortion, when compared with those who did not use these family planning services [adjusted aOR = 1.93, 95 % Confidence Interval: 1.13-3.30]. Accessing either service alone did not contribute to contraceptive use. Age (25-34 vs. 15-24 years) was also statistically associated with contraceptive use. Pregnancy planning status, desire to have more children and education did not contribute to contraceptive use. CONCLUSIONS: In restrictive abortion settings, family planning services offered in the six-month post-abortion period contribute to contraceptive use, if not restricted to simple counseling. Medical consultation, in the absence of contraceptive counseling, makes no difference. Immediate initiation of a contraceptive that suits women's pregnancy intention following an abortion is recommended, as well as a wide range of contraceptive methods, including long-acting reversible methods, even in restrictive abortion laws contexts.

Pilot study of home-based delivery of HIV testing and counseling and contraceptive services to couples in Malawi.

BACKGROUND: HIV counseling and testing for couples is an important component of HIV prevention strategies, particularly in Sub Saharan Africa. The purpose of this pilot study is to estimate the uptake of couple HIV counseling and testing (CHCT) and couple family planning (CFP) services in a single home visit in peri-urban Malawi and to assess related factors. METHODS: This study involved offering CHCT and CFP services to couples in their homes; 180 couples were sampled from households in a peri-urban area of Blantyre. Baseline data were collected from both partners and follow-up data were collected one week later. A pair of male and female counselors approached each partner separately about HIV testing and counseling and contraceptive services and then, if both consented, CHCT and CFP services (pills, condoms and referrals for other methods) were given. Bivariate and multivariate logistic regression analyses were done to examine the relationship between individual partner characteristics and acceptance of the services. Selected behaviors reported pre- and post-intervention, particularly couple reports on contraceptive use and condom use at last sex, were also tested for differences. RESULTS: 89% of couples accepted at least one of the services (58% CHCT-only, 29% CHCT + CFP, 2% CFP-only). Among women, prior testing experience (p < 0.05), parity (p < 0.01), and emotional closeness to partner (p < 0.01) had significant bivariate associations with acceptance of at least one service. Reported condom use at last sex increased from 6% to 25% among couples receiving any intervention. First-ever HIV testing was delivered to 25 women and 69 men, resulting, respectively, in 4 and 11 newly detected infections. CONCLUSIONS: Home-based CHCT and CFP were very successful in this pilot study with high proportions of previously untested husbands and wives accepting CHCT and there were virtually no negative outcomes within one week. This study supports the need for further research and testing of home- and couple-based approaches to expand access to HCT and contraceptive services to prevent the undesired consequences of sexually transmitted infection and unintended pregnancy via unprotected sex.

Discussions of adolescent sexuality in news media coverage of the HPV vaccine.

Given the sexually transmitted nature of human papillomavirus (HPV), some worry the HPV vaccine will create a false sense of security and promote adolescent sexual activity. Media coverage of vaccines can influence social norms, parental attitudes, and vaccine acceptance; in this paper we examine U.S. news media messages related to sexuality and HPV vaccination. Drawing on a structured analysis of 447 articles published during 2005-2009, we qualitatively analyzed a purposive sample of 49 articles discussing adolescent health behaviors related to HPV vaccination. Commonly, articles discussed vaccination in the context of abstinence-only versus comprehensive sexual health education; cited research findings to support vaccination or sex education; argued against connecting vaccination to promiscuous behavior; but included fear-inducing messages. Media messages concerning health behaviors related to HPV vaccination tended to support government and parental involvement in sex education, and dismiss concerns linking vaccination to sexual activity, while also presenting the vaccine as lifesaving.

Family and peer support matter for precoital and coital behaviors among adolescents in Lima.

We analyzed the association between sub-scales developed with adolescents and the outcomes of precoital behaviors and vaginal sex in Lima, Peru. Adolescent participants in key informant sessions operationalized concepts identified during qualitative concept mapping into several sub-scales. Face and content validity testing and pilot application with respondent debriefing were used to refine the sub-scales. Three hundred 15-17 year olds were surveyed about the sub-scales, socio-demographics and sexual behaviors. Exploratory factor analysis confirmed six sub-scales, self-image, goals and decision-making, family education, parental rules/control, school support and peer support, which we regressed on the outcomes. Twice as many males as females reported more than three precoital behaviors and vaginal sex. Higher peer support reduced the likelihood of vaginal sex and precoital behaviors and higher family education reduced precoital behaviors. Results affirm the importance of including adolescents in the entire research process and of sex education with family- and peer-based strategies.

Trends in and Correlates of Short-Acting Contraceptive Stock-Outs: Multicountry Analysis of Performance Monitoring for Action Agile Platform Data.

Understanding trends in contraceptive stock-outs, as well as their structural and demand-side correlates, is critical for policymakers and program managers to identify strategies to further anticipate, reduce, and prevent stock-outs. We analyzed trends as well as supply- and demand-side correlates of short-acting contraceptive method stock-outs by using data from multiple rounds of Performance Monitoring for Action Agile surveys. These data longitudinally measured contraceptive availability over 2 years (between November 2017 and January 2020) across 2,134 public and private service delivery points (SDPs) from urban areas of 5 countries (Burkina Faso, Democratic Republic of the Congo [DRC], India, Kenya, and Nigeria). For each country, we analyzed the trends and used multilevel mixed-effect logistic regression to model the odds of short-acting contraceptive stock-outs, adjusting for key structural and demand-side factors of the SDPs. Stock-outs in short-acting contraceptive methods were common in health facilities and varied markedly, ranging from as low as 2.9% (95% confidence interval [CI]=1.7%, 5.1%) in India to 51.0% (95% CIs=46.8%, 56.0%) in Kenya. During the observation period, stock-out rates decreased by 28% in the SDP samples in India (aOR=0.72, P<.001) and 8% in Nigeria (aOR=0.92, P<.001) but increased by 15% in DRC (aOR=1.15; P=036) and 5% in Kenya (aOR=1.05, P=003) with each round of data collection. Correlates of stock-out rates included the facility managerial authority (private versus public), whether the facility was rated high quality, whether the facility was at an advanced tier, and whether there was high demand for short-acting contraceptives. In conclusion, stock-outs of short-acting contraceptives are still common in many settings. Measuring and monitoring contraceptive stock-outs is crucial for identifying and addressing issues related to the availability and supply of short-acting contraceptives.

Maternal deaths averted by contraceptive use: an analysis of 172 countries.

BACKGROUND: Family planning is one of the four pillars of the Safe Motherhood Initiative to reduce maternal death in developing countries. We aimed to estimate the effect of contraceptive use on maternal mortality and the expected reduction in maternal mortality if the unmet need for contraception were met, at country, regional, and world levels. METHOD: We extracted relevant data from the Maternal Mortality Estimation Inter-Agency Group (MMEIG) database, the UN World Contraceptive Use 2010 database, and the UN World Population Prospects 2010 database, and applied a counterfactual modelling approach (model I), replicating the MMEIG (WHO) maternal mortality estimation method, to estimate maternal deaths averted by contraceptive use in 172 countries. We used a second model (model II) to make the same estimate for 167 countries and to estimate the effect of satisfying unmet need for contraception. We did sensitivity analyses and compared agreement between the models. FINDINGS: We estimate, using model I, that 342,203 women died of maternal causes in 2008, but that contraceptive use averted 272,040 (uncertainty interval 127,937-407,134) maternal deaths (44% reduction), so without contraceptive use, the number of maternal deaths would have been 1·8 times higher than the 2008 total. Satisfying unmet need for contraception could prevent another 104,000 maternal deaths per year (29% reduction). INTERPRETATION: Numbers of unwanted pregnancies and unmet contraceptive need are still high in many developing countries. We provide evidence that use of contraception is a substantial and effective primary prevention strategy to reduce maternal mortality in developing countries. FUNDING: Bill and Melinda Gates Foundation.

Contraception and health.

Increasing contraceptive use in developing countries has cut the number of maternal deaths by 40% over the past 20 years, merely by reducing the number of unintended pregnancies. By preventing high-risk pregnancies, especially in women of high parities, and those that would have ended in unsafe abortion, increased contraceptive use has reduced the maternal mortality ratio--the risk of maternal death per 100,000 livebirths--by about 26% in little more than a decade. A further 30% of maternal deaths could be avoided by fulfilment of unmet need for contraception. The benefits of modern contraceptives to women's health, including non-contraceptive benefits of specific methods, outweigh the risks. Contraception can also improve perinatal outcomes and child survival, mainly by lengthening interpregnancy intervals. In developing countries, the risk of prematurity and low birthweight doubles when conception occurs within 6 months of a previous birth, and children born within 2 years of an elder sibling are 60% more likely to die in infancy than are those born more than 2 years after their sibling.
