Pregnancy and infertility in orthopedics: A review of the current state.

BACKGROUND: Orthopedic surgery continues to have one of the lowest rates of female trainees among all medical specialties in the United States. Barriers to pursuing a surgical residency include the challenges of family planning and work-life balance during training. METHODS: A systematic literature search of articles published between June 2012 and December 2022 in the MEDLINE, EMBASE, and Cochrane databases was performed in January 2023 according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis). Studies were included if they evaluated pregnancy and peripartum experience and/or outcomes amongst orthopedic surgeons or trainees. RESULTS: Eighteen studies were included. Up to 67.3% of female orthopedic surgeons and trainees and 38.7% of their male counterparts delayed childbearing during residency. The most reported reasons for this delay included career choice as an orthopedic surgeon, residency training, and reputational concerns among faculty or co-residents. Infertility ranged from 17.0% to 30.4% in female orthopedic surgeons and up to 31.2% suffered obstetric complications. Assisted Reproductive Technology (ART) resulted in 12.4%-56.3% of successful pregnancies. Maternity and paternity leaves ranged from 1 to 11 weeks for trainees with more negative attitudes associated with maternal leave. CONCLUSIONS: Female orthopedic trainees and attending delay childbearing, experience higher rates of obstetric complications, and more stigma associated with pregnancy compared to their male colleagues. Program and institutional policies regarding maternity and paternity leave are variable across programs, and therefore, attention should be directed toward standardizing policies.

The Impacts of New York State's Paid Family Leave Policy on Parents' Sleep and Exercise.

OBJECTIVES: To assess changes in young parents' health behaviors following implementation of New York State's Paid Family Leave Program (NYSPFL). METHODS: We used synthetic control (N = 117,552) and difference-in-differences (N = 18,973) models with data from the nationally representative Behavioral Risk Factor Surveillance System (BRFSS) from 2011 to 2019 to provide individual-level estimates of the effects of NYSPFL on self-reported exercise in the past month and average daily sleep of adults aged 21-30 years living with one or more children under 18 years of age in New York and comparison states. RESULTS: Synthetic control model results indicate that the NYSPFL increased the likelihood of exercise in the past month among mothers, single parents, and low-income parents by 6.3-10.3% points (pp), whereas fathers showed a decrease in exercise (7.8 pp). Fathers, single parents, and those with two or more children showed increases in daily sleep between 14 and 21 min per day. CONCLUSIONS FOR PRACTICE: State paid family and medical leave laws may provide benefits for health behaviors among young parents with children under 18, particularly those in low-income and single-parent households.

[How to manage parental leave as a self-employed physician?] / Comment gérer un congé parental comme médecin indépendant ?

Under Swiss law, the maternity leave (14 weeks) and paternity leave (2 weeks) allowance, for self-employed individuals as well, shall be 80% of salary, to a maximum of 220 CHF a day, i.e. 6600 CHF a month. This amount is generally insufficient to cover the fixed expenses of the Swiss self-employed physician, which are 19'400 CHF per month on average, and only partly reducible during the leave. The use of personal savings excepted, the obvious solution is replacement, which is already implemented in many other countries, but still poorly developed in Switzerland. A project of an internet platform to centralize supply and demand at federal level is under development.

Selon la loi suisse, le montant de l'allocation parentale, également pour les indépendants (maternité : 14 semaines ; paternité : 2 semaines) correspond à 80 % du salaire, et est d'au maximum 220.- CHF par jour, soit 6600.- CHF par mois. Ce montant est généralement insuffisant pour couvrir les charges des médecins indépendants suisses, qui sont en moyenne de 19 400.- CHF par mois, et seulement partiellement réductibles durant le congé. Hormis le recours aux économies personnelles, la solution qui s'impose est celle du remplacement, déjà fonctionnel dans bien d'autres pays, et encore peu développé en Suisse. Un projet de plateforme de remplacement pour centraliser l'offre et la demande au niveau fédéral est en cours de développement.

Global parental leave in surgical careers: differences according to gender, geographical regions and surgical career stages.

BACKGROUND: There is a lack of information regarding the provision of parental leave for surgical careers. This survey study aims to evaluate the experience of maternity/paternity leave and views on work-life balance globally. METHODS: A 55-item online survey in 24 languages was distributed via social media as per CHERRIES guideline from February to March 2020. It explored parental leave entitlements, attitude towards leave taking, financial impact, time spent with children and compatibility of parenthood with surgical career. RESULTS: Of the 1393 (male : female, 514 : 829) respondents from 65 countries, there were 479 medical students, 349 surgical trainees and 513 consultants. Consultants had less than the recommended duration of maternity leave (43.8 versus 29.1 per cent), no paid maternity (8.3 versus 3.2 per cent) or paternity leave (19.3 versus 11.0 per cent) compared with trainees. Females were less likely to have children than males (36.8 versus 45.6 per cent, P = 0.010) and were more often told surgery is incompatible with parenthood (80.2 versus 59.5 per cent, P < 0.001). Males spent less than 20 per cent of their salary on childcare and fewer than 30 hours/week with their children. More than half (59.2 per cent) of medical students did not believe a surgical career allowed work-life balance. CONCLUSION: Surgeons across the globe had inadequate parental leave. Significant gender disparity was seen in multiple aspects.

Workplace Leave and Breastfeeding Duration Among Postpartum Women, 2016-2018.

Objectives. To examine associations of workplace leave length with breastfeeding initiation and continuation at 1, 2, and 3 months. Methods. We analyzed 2016 to 2018 data for 10 sites in the United States from the Pregnancy Risk Assessment Monitoring System, a site-specific, population-based surveillance system that samples women with a recent live birth 2 to 6 months after birth. Using multivariable logistic regression, we examined associations of leave length (< 3 vs ≥ 3 months) with breastfeeding outcomes. Results. Among 12 301 postpartum women who planned to or had returned to the job they had during pregnancy, 42.1% reported taking unpaid leave, 37.5% reported paid leave, 18.2% reported both unpaid and paid leave, and 2.2% reported no leave. Approximately two thirds (66.2%) of women reported taking less than 3 months of leave. Although 91.2% of women initiated breastfeeding, 81.2%, 72.1%, and 65.3% of women continued breastfeeding at 1, 2, and 3 months, respectively. Shorter leave length (< 3 months), whether paid or unpaid, was associated with lower prevalence of breastfeeding at 2 and 3 months compared with 3 or more months of leave. Conclusions. Women with less than 3 months of leave reported shorter breastfeeding duration than did women with 3 or more months of leave.

The financing need of equitable provision of paid maternal leave in the informal sector in Indonesia: a comparison of estimation methods.

BACKGROUND: Providing an enabling environment for breastfeeding is hampered by the inequitable implementation of paid maternity leave, primarily due to perceived or actual financial costs. To estimate the real cost of paid maternity leave requires using reliable methods. We compared methods utilized in two recent studies in Indonesia. Study A estimated the financial need of providing paid maternity leave in the formal sector with a 10-year forecast at 21% coverage of eligible mothers, while study B estimated similar costs for the informal sector at 100% coverage annually. Results are critical for guiding future application of either method to inform paid maternity leave policies. METHODS: We compared number of covered mothers working informally, total annual cost, and cost per mother. We modified some parameters used in study A (method A) to be similar to study B (method B) for comparison, namely the period of estimate (annual), coverage (100%), estimate of women potentially breastfeeding, exchange rate, female labor force participation rate, the percentage of women working in the informal sector, and adding administration cost. RESULTS: The methods differ in determining the number of mothers working in the informal sector who gave birth, the minimum wage as unit cost, and administrative cost. Both studies estimated the cost at various lengths of leave period. Method A requires more macro (e.g. national/regional) level data, while method B involves (e.g. individual) micro level data. We compared the results of method A with method B, respectively: 1) number of covered mothers working informally were 1,425,589 vs. 1,147,204; 2) total annual costs including administrative costs were US$650,230,167 vs. US$633,942,726, and; 3) cost/mother was US$456 vs US$553. CONCLUSION: Certain flexibilities can be applied to both methods, namely using parameters specific to respective regions (e.g. provincial level parameters), flexible period of analysis, and the use of administrative cost. In a setting where micro data is scarce and not easily accessible, method A provides a feasible approach, while method B will be most appropriate if suitable micro data is available. Future comparison studies in other settings are needed to provide further evidence on the strengths and weaknesses of both methods.

Gender equality and sick leave among first-time parents in Sweden.

Aims: To examine gender equality in the family and sick leave among first-time parents. Methods: Heterosexuals who became first-time parents between 2002 and 2009 (N = 223,332) were identified in national registers. Gender equality in the family was evaluated by parental insurance and income from gainful employment representing the domestic and work spheres respectively and was defined as each parent contributing 40-60% of the family total. The risk of a new medically certified sick-leave spell (>14 days) was evaluated by hazard ratio (HR) using the Cox proportional hazard regression, adjusted for demographic and socioeconomic factors. Results: Gender equality was associated with an increased risk of sick leave compared with traditional roles where women had the main responsibility in the domestic sphere and men in the work sphere (HR 1.30 in women and 1.19 in men). In addition, situations with one partner exposed to double burden or untraditional settings were associated with an increased risk. Conclusions: Equal sharing or taking the lion's share of paid work and domestic responsibilities were associated with an increased risk of sick leave among first-time parents in Sweden. Family-friendly policies are important for facilitating the life of dual earner families, but do not fully counteract the work-life demands of first-time parents.

Precarious working conditions and psychosocial work stress act as a risk factor for symptoms of postpartum depression during maternity leave: results from a longitudinal cohort study.

BACKGROUND: The majority of Western women work during their reproductive years, but past research has often neglected the influence of work-related factors on postpartum mental health. Especially postpartum depression (PPD) is an enormous psychological burden for mothers. Therefore, this study aims to investigate the prospective impact of precarious working conditions and psychosocial work stress during pregnancy (such as work-privacy conflict and effort-reward imbalance at the job) on symptoms of maternal PPD. METHODS: In the prospective-longitudinal cohort study DREAM (DResdner Studie zu Elternschaft, Arbeit und Mentaler Gesundheit), N = 587 employed women were questioned about their work during pregnancy and their mental health 8 weeks after delivery. RESULTS: Multiple regression analyses revealed that work-privacy conflict, low reward at work, and precarious working conditions significantly predicted symptoms of PPD, even when controlling for lifetime depression, anxiety, education, parity, and age. CONCLUSION: Our results indicate that psychosocial work stress and precarious working conditions have important implications for maternal peripartum mental health. They might act as prospective risk factors for PPD during the period of maternal leave. Hence, future research should focus on preventative measures targeting work life.

Disparities in the usage of maternity leave according to occupation, race/ethnicity, and education.

BACKGROUND: Unlike almost all other countries, the United States does not mandate paid maternity leave for mothers. Lack of access to maternity leave may be a risk factor for adverse maternal and child health outcomes. This study sought to assess disparities in the usage of maternity leave according to maternal occupation, race/ethnicity, and education, and to explore the relationships between these factors. METHODS: We used data from the Pregnancy Risk Assessment Monitoring System from the years 2016 and 2017. We calculated the prevalence of usage of maternity leave and paid maternity leave according to the mother's age, race/ethnicity, education, state, and occupation. We constructed regression models to explore the bivariate and mutually adjusted associations between these factors and usage of maternal leave. RESULTS: Usage of maternity leave and paid maternity leave were estimated at 89.3% and 49.0%, respectively. Usage of paid maternity leave was lower in younger mothers, in Black and Hispanic mothers, and in mothers with fewer years of education. Workers in several occupations, including building and grounds cleaning and maintenance, personal care, and food preparation and serving, used maternity leave at rates significantly lower than the average of all workers. Adjustment for education and occupation reduced, but did not obviate, racial/ethnic differentials in usage of paid maternity leave. CONCLUSIONS: There are substantial differentials in usage of maternity leave. Further research could examine whether these differences contribute to disparities in maternal and child health outcomes.

Cash support vs. tax incentives: The differential impact of policy interventions on third births in contemporary Hungary.

Following steep falls in birth rates in Central and Eastern European countries during the economic and institutional restructuring of the early 1990s, governments made substantial efforts to stop or at least reduce the fertility decline. In Hungary, parents with three or more children could benefit from specific new policy measures: the flat-rate child-rearing support paid from the youngest child's third to eighth birthdays (signalling recognition of stay-at-home motherhood) and a redesigned and upgraded tax relief system. However, the success of these policy measures, if any, is difficult to detect in aggregate statistics. Analysing data from the Hungarian Generations and Gender Survey, we rely on event history methods to examine the policies' effects on third birth risks, especially among different socio-economic groups. The results indicate that while the child-rearing support increased third birth risks among the least educated, the generous tax relief had a similar effect for parents with tertiary education.

Pregnancy and parental leave among plastic surgery residents in Canada: a nationwide survey of attitudes and experiences.

SUMMARY: Small surgical residency programs like plastic surgery can be challenging environments to accommodate parental leave. This study aimed to report the experiences, attitudes and perceived support of Canadian plastic surgery residents, recent graduates and staff surgeons with respect to pregnancy and parenting during training. Residents and staff surgeons were invited via email to participate in an online survey. The results presented here explore experiences of pregnancy and parental leave of current plastic surgery residents and staff surgeons. Residents' and staff surgeons' perceptions of program director support, policies, negative comments and the impact of parental leave on the workload of others were also explored. Although the findings suggest that there may be improvements in the support of program directors, there continues to be a negative attitude in surgical culture toward pregnancy during residency. The perceived confusion of respondents with respect to programspecific policies emphasizes the need for open conversations and standardization of parental leave.

Parental Leave, Lactation, and Childcare Policies at Top US Schools of Public Health.

OBJECTIVES: To describe policies related to parental leave, breastfeeding, and childcare for faculty and staff at top schools of public health in the United States. METHODS: We identified the top 25 schools of public health from the US News and World Report rankings. We reviewed each institutional Web site to identify publicly available policies as of July 2018. RESULTS: For birth mothers, 80% (20/25) of the schools provided paid childbearing leave to faculty (mean = 8.2 weeks), and 48% (12/25) provided paid childbearing leave for staff (mean = 5.0 weeks). For nonbirth parents, 68% (17/25) provided paid parental leave for faculty and 52% (13/25) for staff (range = 1-15 weeks). We found that 64% (16/25) of the schools had publicly available lactation policies, and 72% (18/25) of the schools had at least 1 university-run on-campus childcare center. CONCLUSIONS: The majority of top US schools of public health provide paid leave to faculty birth mothers. However, most schools fall short of the 14 weeks recommended by the American Public Health Association.

Access to Paid Parental Leave for Academic Surgeons.

BACKGROUND: Parental leave is linked to health benefits for both child and parent. It is unclear whether surgeons at academic centers have access to paid parental leave. The aim of this study was to determine parental leave policies at the top academic medical centers in the United States to identify trends among institutions. METHODS: The top academic medical centers were identified (US News & World Report 2016). Institutional websites were reviewed, or human resource departments were contacted to determine parental leave policies. "Paid leave" was defined as leave without the mandated use of personal time off. Institutions were categorized based on geographical region, funding, and ranking to determine trends regarding availability and duration of paid parental leave. RESULTS: Among the top 91 ranked medical schools, 48 (53%) offer paid parental leave. Availability of a paid leave policy differed based on private versus public institutions (70% versus 38%, P < 0.01) and on medical center ranking (top third = 77%; middle third = 53%; and bottom third = 29%; P < 0.01) but not based on region (P = 0.06). Private institutions were more likely to offer longer paid leaves (>6 wk) than public institutions (67% versus 33%; P = 0.02). No difference in paid leave duration was noted based on region (P = 0.60) or rank (P = 0.81). CONCLUSIONS: Approximately, 50% of top academic medical centers offer paid parental leave. Private institutions are more likely to offer paid leave and leave of longer duration. There is considerable variability in access to paid parenteral leave for academic surgeons.

Fellowship or Family? A Comparison of Residency Leave Policies With the Family and Medical Leave Act.

BACKGROUND: In 1993, the Family and Medical Leave Act (FMLA) mandated 12 weeks of unpaid, job-protected leave. The current impact of taking 12 weeks of leave during residency has not been evaluated. METHODS: We examined the 2018 Accreditation Council for Graduate Medical Education (n = 24) specialty leave policies to determine the impact of 6- and 12-week leave on residency training, board eligibility, and fellowship training. We compared our findings with a 2006 study. RESULTS: In 2018, five (21%) specialties had policy language regarding parental leave during residency, and four (16%) had language regarding medical leave. Median leave allowed was 4 weeks (IQR 4-6). Six specialties (25%) decreased the number of weeks allowed for leave from 2006 to 2018. In 2006, a 6-week leave would cause a 1-year delay in board eligibility in six specialties; in 2018, it would not cause delayed board eligibility in any specialty. In 2018, a 12-week (FMLA) leave would extend training by a median of 6 weeks (mean 4.1, range 0-8), would delay board eligibility by 6-12 months in three programs (mean 2.25, range 0-12), and would delay fellowship training by at least 1 year in 17 specialties (71%). The impact of a 12-week leave was similar between medical and surgical specialties. CONCLUSIONS: While leave policies have improved since 2006, most specialties allow for 6 weeks of leave, less than half of what is mandated by the FMLA. Moreover, a 12-week, FMLA-mandated leave would cause significant delays in board certification and entry into fellowship for most residency programs.

Breastfeeding Rates and Programs in Europe: A Survey of 11 National Breastfeeding Committees and Representatives.

INTRODUCTION: Among the world's regions, the WHO European Region has the lowest rates of exclusive breastfeeding at the age of 6 months with approximately 25%. Low rates and early cessation of breastfeeding have important adverse health consequences for women, infants, and young children. Protecting, promoting, and supporting breastfeeding are a public health priority. OBJECTIVES: National breastfeeding data and monitoring systems among selected European countries and the WHO European Region are compared. Mechanisms for the support, protection, and promotion of breastfeeding are reviewed and successes and challenges in implementation of national programs are presented. METHODS: National representatives of national breastfeeding committees and initiatives in 11 European countries, including Belgium, Croatia, Denmark, Germany, Ireland, Italy, The Netherlands, Norway, Spain, Sweden, and Switzerland, participated in a standardized survey. Results are evaluated and compared in a narrative review. RESULTS: Variation exists in Europe on breastfeeding rates; methodology for data collection; and mechanisms for support, protection, and promotion of breastfeeding. Directly after birth, between 56% and 98% of infants in all countries were reported to receive any human milk, and at 6 months 38% to 71% and 13% to 39% of infants to be breastfed or exclusively breastfed, respectively. National plans addressing breastfeeding promotion, protection, and support exist in 6 of the 11 countries. CONCLUSIONS: National governments should commit to evidence-based breastfeeding monitoring and promotion activities, including financial and political support, to improve breastfeeding rates in the Europe. Renewed efforts for collaboration between countries in Europe, including a sustainable platform for information exchange, are needed.

Maternal work and exclusive breastfeeding in Mansoura, Egypt.

BACKGROUND: Working mothers face unique barriers to breastfeeding, despite the compelling evidence of its benefits. The aim of this study was to describe exclusive breastfeeding (EBF) rate of working mothers and associated factors. METHODS: Cross-sectional study was carried out in Mansoura District, Egypt from 1 July to 31 December 2017 among working mothers attending health care facilities for vaccinating their infants aged 6 months. Data were collected using a questionnaire covering sociodemographic and occupational data; breastfeeding supportive workplace facilities; antenatal and natal care; infant's data; and EBF practice. RESULTS: EBF rate was 14.1%. Independent predictors were being still on work leave, return to work 4 months after childbirth, working as farmer/manual worker and in trades and business, and being self/family employed. CONCLUSIONS: EBF rate is low among working mothers. There is a need to extend maternity leave and provide promoting workplace facilities.

Work ability and work functioning: measuring change in individuals recently returned to work.

PURPOSE: To assess: (1) whether work ability and work-functioning instruments can detect relevant changes in their respective parameters following a return to work (RTW) and (2) what proportion of those returning to work show changes in their work ability and work functioning. METHODS: A total of 1073 workers who returned to work after at least 2 weeks of sick leave were invited to fill out three questionnaires in the first 8 weeks after RTW. These consisted of an appraisal of general, physical, and mental/emotional work ability (scores 0-10) and a work-functioning questionnaire (scores 0-100). Minimal Important Change (MIC) was defined to determine the proportion of people, whose scores had changed at weeks 5 and 8 following RTW. The Smallest Detectable Change (SDC) was determined to put the MIC in perspective of measurement error. RESULTS: Of all participants, 235 were eligible for the analysis. All MIC values were below the SDC and thus not suitable for use. The SDC for work ability was 2.2 and 19.9 for work functioning. In the first 5 weeks after RTW, 10-15% showed a relevant, measurable improvement in work ability, and work functioning based on the SDC margins. CONCLUSIONS: Both instruments were unable to identify change after RTW adequately. We can conclude that 10-15% of individuals showed improvement in work ability and work functioning in the first 5 weeks after RTW when SDC is used.

Maternity or parental leave and breastfeeding duration: Results from the ELFE cohort.

Previous studies have shown a high level of noncompliance with recommendations on breastfeeding duration, especially in France. The objective was to describe the association between breastfeeding initiation and duration and the statutory duration of postnatal maternity leave, the gap between the end of legal maternity leave and the mother's return to work, and maternal working time during the first year post-partum. Analyses were based on 8,009 infants from the French nationwide ELFE cohort. We assessed the association with breastfeeding initiation by using logistic regression and, among breastfeeding women, with categories of breastfeeding duration by using multinomial logistic regression. Among primiparous women, both postponing return to work for at least 3 weeks after statutory postnatal maternity leave (as compared with returning to work at the end of the statutory period) and working less than full-time at 1 year post-partum (as compared with full-time) were related to higher prevalence of breastfeeding initiation. Among women giving birth to their first or second child, postponing the return to work until at least 15 weeks was related to a higher prevalence of long breastfeeding duration (at least 6 months) as compared with intermediate duration (3 to <6 months). Working part-time was also positively related to breastfeeding duration. Among women giving birth to their third child or more, working characteristics were less strongly related to breastfeeding duration. These results support extending maternity leave or working time arrangements to encourage initiation and longer duration of breastfeeding.

Maternity Leave and Mothers' Long-Term Sickness Absence: Evidence From West Germany.

Exploiting unique German administrative data, we estimate the association between an expansion in maternity leave duration from two to six months in 1979 and mothers' postbirth long-term sickness absence over a period of three decades after childbirth. Adopting a difference-in-difference approach, we first assess the reform's labor market effects and, subsequently, prebirth and postbirth maternal long-term sickness absence, accounting for the potential role of the reform in mothers' selection into employment. Consistent with previous research, our estimates show that the leave extension caused mothers to significantly delay their return to work within the first year after childbirth. We then provide difference-in-difference estimates for the number and length of spells of long-term sickness absence among returned mothers. Our findings suggest that among those returned, mothers subject to the leave extension exhibit a higher incidence of long-term sickness absence compared with mothers who gave birth before the reform. This also holds true after we control for observable differences in prebirth illness histories. At the same time, we find no pronounced effects on mothers' medium-run labor market attachment following the short-run delay in return to work, which might rationalize a negative causal health effect. Breaking down the results by mothers' prebirth health status suggests that the higher incidence of long-term sickness absence among mothers subject to the reform may be explained by the fact that the reform facilitated the reentry of a negative health selection into the labor market.

Maternity leave duration and adverse pregnancy outcomes: An international country-level comparison.

AIM: Preterm birth and low birthweight (LBW) lead to infant morbidity and mortality. The causes are unknown. This study evaluates the association between duration of maternity leave and birth outcomes at country level. METHOD: We compiled data on duration of maternity leave for 180 countries of which 36 specified prenatal leave, 190 specified income, 183 specified preterm birth rates and 185 specified the LBW rate. Multivariate and seemingly unrelated regression analyses were done in STATA. RESULTS: Mean maternity leave duration was 15.4 weeks ( SD=7.7; range 4-52 weeks). One additional week of maternity leave was associated with a 0.09% lower preterm rate (95% confidence interval [CI] -0.15 to -0.04) adjusting for income and being an African country. An additional week of maternity leave was associated with a 0.14% lower rate of LBW (95% CI -0.24 to -0.05). Mean prenatal maternity leave across 36 countries was six weeks ( SD=2.7; range 2-14 weeks). One week of prenatal maternity leave was associated with a 0.07% lower preterm rate (95% CI -0.10 to 0.24) and a 0.06% lower rate of LBW (95% CI -0.14 to 0.27), but these results were not statistically significant. By adjusting for income status categories, the preterm birth rate was 1.53% higher and the LBW rate was 2.17% higher in Africa compared to the rest of the world. CONCLUSIONS: Maternity leave duration is significantly associated with birth outcomes. However, the association was not significant among 36 countries that specified prenatal maternity leave. Studies are needed to evaluate the correlation between prenatal leave and birth outcomes.
