Investigating the relationship between spousal violence against women and total fertility rate in Afghanistan.

BACKGROUND: spousal violence against women (SVAW) is a common form of violence that occurs within the family context, with spouses being the main perpetrators. Afghanistan has one of the highest rates of SVAW in the world, and its impact on reproductive health and fertility is not well understood. This study aims to investigate the extent to which SVAW influences the total fertility rate (TFR) of Afghan women. METHODS: In this study, a regression model of discrete-time survival models was used to calculate the total fertility rate (TFR), parity progression ratio (PPRs), and average closed birth intervals (CBI) between two children. The method used in this study has its roots in the works of Griffin Finney (1983) and was further developed by Redford et al. (2010). The study population utilized the 2015 Afghanistan Demographic and Health Survey, and sample weights were used to ensure accurate estimates for the population of Afghanistan as a whole. RESULTS: The study found that women in Afghanistan who have experienced SV are more likely to progress to the next parity, start childbearing faster, and continue to do so. Women who have not experienced SV tend to progress to higher parities at a slower pace during their initial reproductive years. The study also suggests that women with spousal violence (SV) experience may have slightly higher fertility rates and shorter birth intervals for certain birth orders, although the differences between the two groups are generally small. Specifically, the total fertility rate (TFR) for women who experienced SV was 6.9, while the TFR for women who did not experience SV was 6.2. CONCLUSIONS: These results provide valuable information for policymakers and public health professionals in developing effective policies and programs to address SVAW and improve maternal and child health outcomes in Afghanistan.

Birth Spacing and Parents' Physical and Mental Health: An Analysis Using Individual and Sibling Fixed Effects.

An extensive literature has examined the relationship between birth spacing and subsequent health outcomes for parents, particularly for mothers. However, this research has drawn almost exclusively on observational research designs, and almost all studies have been limited to adjusting for observable factors that could confound the relationship between birth spacing and health outcomes. In this study, we use Norwegian register data to examine the relationship between birth spacing and the number of general practitioner consultations for mothers' and fathers' physical and mental health concerns immediately after childbirth (1-5 and 6-11 months after childbirth), in the medium term (5-6 years after childbearing), and in the long term (10-11 years after childbearing). To examine short-term health outcomes, we estimate individual fixed-effects models: we hold constant factors that could influence parents' birth spacing behavior and their health, comparing health outcomes after different births to the same parent. We apply sibling fixed effects in our analysis of medium- and long-term outcomes, holding constant mothers' and fathers' family backgrounds. The results from our analyses that do not apply individual or sibling fixed effects are consistent with much of the previous literature: shorter and longer birth intervals are associated with worse health outcomes than birth intervals of approximately 2-3 years. Estimates from individual fixed-effects models suggest that particularly short intervals have a modest negative effect on maternal mental health in the short term, with more ambiguous evidence that particularly short or long intervals might modestly influence short-, medium-, and long-term physical health outcomes. Overall, these results are consistent with small to negligible effects of birth spacing behavior on (non-pregnancy-related) parental health outcomes.

Association of the second birth mode of delivery and interval with maternal pelvic floor changes: a prospective cohort study.

BACKGROUND: This study aimed to explore the association of the second birth delivery mode and interval with maternal pelvic floor changes. METHODS: This prospective cohort study included women who had a first delivery and were in weeks 36-41 of a subsequent pregnancy at Panzhihua Central Hospital between July 2017 and June 2018. The primary outcomes of the study were the hiatus area at 6 months postpartum and bladder neck (mm) at rest and during a maximum Valsalva maneuver. RESULTS: There were 112 women with vaginal delivery and 182 with Cesarean section. The hiatus area and hiatus circumference decreased at all time points (all P < 0.001). The women with Cesarean section had a smaller hiatus area and circumference (P < 0.001 and P < 0.001). The hiatus diameters decreased with time in both groups (all P < 0.001) and were smaller after Cesarean section (both P < 0.001). The bladder neck at maximum Valsalva increased with time (all P < 0.001) without significant differences between the two groups. Finally, the proportion of patients with POP-Q stage 0/I increased with time in both groups (all P < 0.001), with the proportions being higher in the Cesarean group (P = 0.002). The birth interval was negatively correlated with the hiatus area (B=-0.17, 95%CI: -0.25, -0.08, P < 0.001) and positively correlated with the bladder neck at rest (B = 0.22, 95%CI: 0.08, 0.35, P = 0.001) and at maximum Valsalva (B = 0.85, 95%CI: 0.65, 1.05, P < 0.001). CONCLUSIONS: In conclusion, the mode of delivery at the second birth could influence the hiatus area and circumference and bladder neck size. The birth interval was negatively correlated with the hiatus area and positively correlated with the bladder neck at rest and at maximum Valsalva.

Reproductive Interconception Care Among Women Recently Pregnant and Homeless: A Qualitative Analysis.

Reproductive interconception care provided at maternal postpartum visits may help reduce unintended pregnancies and elongate birth intervals for women experiencing homelessness. To improve interconception care uptake, this qualitative study aimed to identify barriers and facilitators to reproductive interconception care from the perspectives of women who were recently pregnant and homeless. A semi-structured interview guide and demographic survey were developed based on epidemiological findings, Information-Motivation-Behavioral Skill framework components, and a review by community health workers for content validity. After conducting 12 interviews with women recently pregnant and homeless in a local continuum of care in 2022, audio-recorded interviews were transcribed, iteratively coded using a priori and emerging codes, and thematically analyzed. Key themes were identified to determine implications and next steps to improving reproductive interconception care uptake. Interrelated themes focused on information (e.g., knowledge and misconceptions about pregnancy, birth intervals, contraception), motivation (e.g., attitudes about interconception care experiences, perinatal social influences), behavioral skills (e.g., objective ability to obtain interconception care and perceived self-efficacy related to attending maternal postpartum visits and increasing birth intervals), and macro-level factors (e.g., obtaining housing, contextualizing socioeconomic factors, navigating COVID-19). The findings suggest the need for flexible, streamlined, and personalized interconception care delivery that acknowledges pressing housing and relationship considerations and supports women's autonomy. Improvements to reproductive interconception care may reduce future unintended pregnancies, increase birth intervals, and improve birth outcomes among women experiencing homelessness.

Homelessness in the Perinatal Period and Associations With Reproductive Interconception Care: 2016-2019 Pregnancy Risk Assessment Monitoring System.

OBJECTIVES: Women experiencing homelessness have higher rates of unintended pregnancy than stably housed women and may benefit from reproductive interconception care. How reproductive interconception care differs between women who did and did not experience perinatal homelessness is not known. We estimated prevalence ratios of reproductive interconception behaviors among US women experiencing homelessness during the perinatal period. METHODS: We used data from the 2016-2019 Pregnancy Risk Assessment Monitoring System to calculate the prevalence of 5 reproductive interconception care outcomes: attending a maternal postpartum checkup, participating in a conversation with a health care provider about birth intervals, receiving family planning counseling, obtaining a prescription for short-acting contraception, and having a long-acting reversible contraceptive inserted. We used complex survey weights, stratified by perinatal homelessness, and converted adjusted logistic regression odds ratios between housing status and outcome variables to adjusted prevalence ratios (aPRs) and 95% CIs. RESULTS: Among participants, approximately 2.4% (weighted percentage; unweighted 2953 of 100 706) experienced homelessness sometime in the 12 months before their children were born; the majority were non-Hispanic (83.2%) and White (69.4%), were not married (82.2%), and had public health insurance (56.8%). Perinatal homelessness was significantly associated with a lower prevalence of attending a postpartum maternal visit (aPR = 0.90; 95% CI, 0.87-0.94) and a higher prevalence of having a conversation about birth intervals with their health care providers (aPR = 1.13; 95% CI, 1.03-1.21). CONCLUSIONS: Findings suggest that improving attendance at postpartum visits and evaluating birth interval conversations may strengthen interconception care practices while contextualizing social determinants such as housing stability. Improving uptake of postpartum visits may reduce unintended pregnancy, short birth intervals, and adverse birth outcomes in future pregnancies among women experiencing homelessness.

Life history impacts on infancy and the evolution of human social cognition.

Greater longevity, slower maturation and shorter birth intervals are life history features that distinguish humans from the other living members of our hominid family, the great apes. Theory and evidence synthesized here suggest the evolution of those features can explain both our bigger brains and our cooperative sociality. I rely on Sarah Hrdy's hypothesis that survival challenges for ancestral infants propelled the evolution of distinctly human socioemotional appetites and Barbara Finlay and colleagues' findings that mammalian brain size is determined by developmental duration. Similar responsiveness to varying developmental contexts in chimpanzee and human one-year-olds suggests similar infant responsiveness in our nearest common ancestor. Those ancestral infants likely began to acquire solid food while still nursing and fed themselves at weaning as chimpanzees and other great apes do now. When human ancestors colonized habitats lacking foods that infants could handle, dependents' survival became contingent on subsidies. Competition to engage subsidizers selected for capacities and tendencies to enlist and maintain social connections during the early wiring of expanding infant brains with lifelong consequences that Hrdy labeled "emotionally modern" social cognition.

Estimates of life history parameters in a high latitude, arid-country vervet monkey population.

We present data on life history parameters from a long-term study of vervet monkeys in the Eastern Cape, South Africa. Estimates are presented of age at first conception for females and age at natal dispersal for males, along with the probability of survival to adulthood for infants born during the study, female reproductive life-span, reproductive output (including lifetime reproductive success for a subset of females), and inter-birth interval (IBI) duration. We also assess the effect of maternal age and infant survival on length of IBI. We then go on to compare life history parameters for our population with those from two East African populations in Kenya (Amboseli and Laikipia). We find there is broad consensus across the three populations, although mean infant survival was considerably lower for the two East African sites. Such comparisons must be made cautiously, however, as local ecology across the duration of the studies obviously has an impact on the estimates obtained. With this caveat in place, we consider that the concordance between values is sufficient to enable the values reported here to be used in comparative studies of primate life history, although data from habitats with higher rainfall and lower levels of seasonality are needed, and the results presented here should not be seen as canonical.

The influence of birth outcomes and pregnancy complications on interpregnancy interval: a quantile regression analysis.

PURPOSE: To ascertain whether adverse pregnancy outcomes at first pregnancy influence subsequent interpregnancy intervals (IPIs) and whether the size of this effect varies with IPI distribution METHODS: We included 251,892 mothers who gave birth to their first two singletons in Western Australia, from 1980 to 2015. Using quantile regression, we investigated whether gestational diabetes, hypertension, or preeclampsia in the first pregnancy influenced IPI to subsequent pregnancy and whether effects were consistent across the IPI distribution. We considered intervals at the 25th centile of the distribution as 'short' and the 75th centile as 'long'. RESULTS: The average IPI was 26.6 mo. It was 0.56 mo (95% CI: 0.25-0.88 mo) and 1.12 mo (95% CI: 0.56 - 1.68 mo) longer after preeclampsia, and gestational hypertension respectively. There was insufficient evidence to suggest that the association between previous pregnancy complications and IPI differed by the extent of the interval. However, associations with marital status, race/ethnicity and stillbirth contributed to either shortening or prolonging IPIs differently across the distribution of IPI. CONCLUSION: Mothers with preeclampsia and gestational hypertension had slightly longer subsequent IPIs than mothers whose pregnancies were not complicated by these conditions. However, the extent of the delay was small (<2 mo).

Association between interpregnancy interval and pregnancy complications in multiparas / 中华围产医学杂志

Objective:To explore the influence of interpregnancy interval (IPI) on pregnancy complications in multiparas.Methods:This was a retrospective cohort study involving 7 669 singleton parturients who delivered at ≥28 gestational weeks in the Affiliated Hospital of Southwest Medical University between December 2015 and December 2020 and had given birth in the third trimester before. Clinical data were collected, including the baseline characteristics, pregnancy complications, gestational weeks at delivery, and neonatal birth weight. According to the IPI, these women were divided into five groups: <12 months ( n=350), 12-<24 months ( n=945), 24-<60 months ( n=2 544), 60-<120 months ( n=2 478), and ≥120 months ( n=1 352). Based on the recommendation of the World Health Organization, pregnant women with an IPI of 24-<60 months were the control group. A multivariate logistic model was used to adjust for confounders and calculate the risks of pregnancy complications, including gestational diabetes mellitus (GDM) and hypertensive disorders of pregnancy (HDP). The influences of maternal age and previous delivery mode on the associations between IPI and maternal complications were analyzed. Analysis of variance (ANOVA), Chi-square test, and Cochran-Mantel-Haenszel Chi-square test were used for statistical analysis. Results:Compared with the control group, the incidence of GDM and HDP increased in the 60-<120 months group ( OR=1.23, 95% CI: 1.01-1.48 and OR=1.47, 95% CI: 1.13-1.92) and ≥120 months group ( OR=1.37, 95% CI:1.07-1.78 and OR=1.92, 95% CI: 1.39-2.64); the risks of uterine rupture/postpartum hemorrhage and placental abruption increased in the <12 months group ( OR=1.54, 95% CI: 1.01-2.34) and 12-<24 months group ( OR=2.38 95% CI: 1.13-5.02), respectively. In the 60-<120 months group, the risk of GDM increased only in non-elderly women (adjusted OR=1.71, 95% CI: 1.36-2.14), so did the risks of GDM and HDP in the ≥120 months group (adjusted OR=3.11, 95% CI: 2.10-4.62 and adjusted OR=1.81, 95% CI: 1.12-2.91). Among women who had undergone a previous cesarean section, the risk of GDM increased in the ≥120 months group (adjusted OR=1.35, 95% CI: 1.00-1.81). In the 60-<120 months group and ≥120 months group, the risk of HDP increased in postpartum women (adjusted OR=1.79, 95% CI: 1.08-2.95 and adjusted OR=3.32, 95% CI: 1.91-5.77). Conclusion:IPI≥60 months is a risk factor for GDM and HDP, and the associations between IPI and maternal complications are influenced by maternal age.

Effect of birth interval on maternal and infant outcomes in patients with gestational diabetes mellitus / 中华围产医学杂志

Objective:To investigate the effects of birth intervals on maternal and infant outcomes in pregnant women with gestational diabetes mellitus (GDM).Methods:This retrospective study recruited 445 pregnant women with GDM who received prenatal examinations and delivered in Peking University First Hospital-Ningxia Women Children's Hospital from January 2020 to December 2021. Based on the birth interval classification standard recommended by WHO and the American College of Obstetricians and Gynecologists, these subjects were divided into three groups: shorter group (<18 months, n=69), normal group (18-59 months, n=213) and longer group (≥60 months, n=163). Analysis of variance, Chi-square test, and multivariate logistic regression model were used for statistical analysis. Results:There were statistically significant differences in the maternal age at this and previous pregnancy [(30.6±4.1), (30.8±3.8) vs (32.7±3.7) years; (22.7±2.4), (26.3±2.9) vs (29.9±4.1) years] and the incidence of oligohydramnios [10.1% (7/69), 1.9% (4/213) vs 3.1% (5/163)] and preterm birth [14.5% (10/69), 5.2% (11/213) vs 1.8% (3/163)] between the shorter, normal, and longer groups (all P<0.05). After adjusting for confounding factors in the present pregnancy, the risks of oligohydramnios, preterm birth, and low birth weight increased in the shorter group [ OR (95% CI): 4.73 (1.75-12.85), 5.54 (1.37-22.42) and 9.54 (3.05-29.82), all P<0.05] and so did the risk of postpartum hemorrhage in the longer group [ OR (95% CI): 4.45 (1.72-11.49), P<0.05]. Conclusions:Both longer and shorter birth intervals can affect maternal and infant outcomes of GDM patients. Postpartum healthcare should be strengthened for GDM patients who desire more children to help them maintain an appropriate birth interval, thus promoting maternal and infant health.

Interpregnancy Interval and Birth Outcomes: A Propensity Matching Study in the California Population.

INTRODUCTION: Previous studies that used traditional multivariable and sibling matched analyses to investigate interpregnancy interval (IPI) and birth outcomes have reached mixed conclusions about a minimum recommended IPI, raising concerns about confounding. Our objective was to isolate the contribution of interpregnancy interval to the risk for adverse birth outcomes using propensity score matching. METHODS: For this retrospective cohort study, data were drawn from a California Department of Health Care Access and Information database with linked vital records and hospital discharge records (2007-2012). We compared short IPIs of < 6, 6-11, and 12-17 months to a referent IPI of 18-23 months using 1:1 exact propensity score matching on 13 maternal sociodemographic and clinical factors. We used logistic regression to calculate the odds of preterm birth, early-term birth, and small for gestational age (SGA). RESULTS: Of 144,733 women, 73.6% had IPIs < 18 months, 5.5% delivered preterm, 27.0% delivered early-term, and 6.0% had SGA infants. In the propensity matched sample (n = 83,788), odds of preterm birth were increased among women with IPI < 6 and 6-11 months (OR 1.89, 95% CI 1.71-2.0; OR 1.22, 95% CI 1.13-1.31, respectively) and not with IPI 12-17 months (OR 1.01, 95% CI 0.94-1.09); a similar pattern emerged for early-term birth. The odds of SGA were slightly elevated only for intervals < 6 months (OR 1.10, 95% CI 1.00-1.20, p < .05). DISCUSSION: This study demonstrates a dose response association between short IPI and adverse birth outcomes, with no increased risk beyond 12 months. Findings suggest that longer IPI recommendations may be overly proscriptive.

Maternal factors associated with interbirth intervals in Australia: Results from a population-based longitudinal study.

BACKGROUND AND OBJECTIVE: Short and long intervals between successive births are associated with adverse birth outcomes, especially in low-income and middle-income countries, yet the birth intervals in high-income countries remain relatively understudied. The aim was to examine maternal factors associated with birth intervals in Australia. METHODS: The sample comprised 6130 participants in the Australian Longitudinal Study on Women's Health who were born in 1973-1978, had two or more births, and responded to regular surveys between 1996 and 2018. Interbirth interval (IBI) was defined as the time between successive live births. Maternal factors were examined using accelerated failure time models. RESULTS: For women with only two births (n = 3802), the median time to the second birth was 34.0 months (IQR 23.1, 46.2) with shorter IBI associated with higher socioeconomic status (eg, university education (31.9 months), less income stress (31.1)), and longer IBI associated with age over 35 (39.7), fair/poor health (43.0), untreated fertility problems (45.5), miscarriage (39.4), or abortion (41.0). For women with three or more births (n = 2328), the median times to the second and third births were 31.2 months (19.9, 42.1) and 36.5 months (25.3, 50.1), respectively; some factors were consistent between the first IBI and second IBI (eg, university education and being married were associated with shorter IBI), whereas income stress was associated with longer first IBI but not with second IBI. CONCLUSIONS: Understanding maternal factors associated with birth intervals in a high-income country like Australia may enable more nuanced tailoring of guidelines for prepregnancy care.

Impact of interpregnancy interval on long-term childhood neoplasm of the offspring.

BACKGROUND: The possible impact of interpregnancy interval (IPI) on perinatal outcomes has long been studied, however, a definition of the optimal interval is still not clear. Both short and long IPIs have been associated with obstetrical syndromes and short and long-term complications. In this study, we sought to explore the impact of IPI on the hazard for neoplasm of the offspring, thus contribute to the present literature in determining the preferred birth spacing. OBJECTIVE: We aim to investigate the association between short and long IPIs and the hazard for childhood neoplasm of the offspring. METHODS: A population-based retrospective cohort analysis comparing offspring neoplasm hazard following three different IPIs. Exposure was defined as short (<6 months), or long (>60 months) IPIs, whereas intermediate IPI (6 months - 60 months) served as the comparison group. The study included singleton live births in a tertiary regional hospital between 1991 and 2014. Offspring were followed for 18 years, and all hospitalization records for neoplasm diagnoses were collected. Kaplan-Meier survival curves were used for the cumulative incidence of neoplasm morbidity, and Cox proportional hazards models were used to control for confounders. RESULTS: During the study period, 144,397 deliveries met the inclusion criteria. Of those, 18,947 (13.1%) occurred in women with short IPI, 114,012 (79%) in women with intermediate IPI, and 11,438 (7.9%) in women with long IPI. 61 benign neoplasms and 80 malignant neoplasms were registered in offspring born after long IPI. The total percentage of neoplasm were the highest in the long IPI group versus the intermediate and short IPI groups (malignant - 0.7%, 0.6%, 0.5% respectively, benign - 0.5%, 0.4%, 0.3% respectively). Controlling for maternal age, diabetes mellitus, preterm delivery, birth weight, smoking, cesarean section, and fertility treatments, long IPI was found to be independently associated with high hazard for long-term pediatric neoplasm related hospitalizations (adjusted HR 1.39, 95% CI 1.09, 1.77). Short IPI may be associated to decreased hazard for childhood neoplasms (adjusted HR 0.74, 95% Cl 0.59, 0.92). CONCLUSIONS: Long IPI is associated with a high hazard for childhood neoplasms, compared with intermediate and short IPIs. Short IPI may be associated with decreased hazard for childhood neoplasms.

Optimal interpregnancy interval in autism spectrum disorder: A multi-national study of a modifiable risk factor.

It is biologically plausible that risk of autism spectrum disorder (ASD) is elevated by both short and long interpregnancy intervals (IPI). We conducted a retrospective cohort study of singleton, non-nulliparous live births, 1998-2007 in Denmark, Finland, and Sweden (N = 925,523 births). Optimal IPI was defined as the IPI at which minimum risk was observed. Generalized additive models were used to estimate relative risks (RR) of ASD and 95% Confidence Intervals (CI). Population impact fractions (PIF) for ASD were estimated under scenarios for shifts in the IPI distribution. We observed that the association between ASD (N = 9302) and IPI was U-shaped for all countries. ASD risk was lowest (optimal IPI) at 35 months for all countries combined, and at 30, 33, and 39 months in Denmark, Finland, and Sweden, respectively. Fully adjusted RRs at IPIs of 6, 12, and 60 months were 1.41 (95% CI: 1.08, 1.85), 1.26 (95% CI: 1.02, 1.56), and 1.24 (95% CI: 0.98, 1.58) compared to an IPI of 35 months. Under the most conservative scenario PIFs ranged from 5% (95% CI: 1%-8%) in Denmark to 9% (95% CI: 6%-12%) in Sweden. The minimum ASD risk followed IPIs of 30-39 months across three countries. These results reflect both direct IPI effects and other, closely related social and biological pathways. If our results reflect biologically causal effects, increasing optimal IPIs and reducing their indications, such as unintended pregnancy and delayed age at first pregnancy has the potential to prevent a salient proportion of ASD cases. LAY SUMMARY: Waiting 35 months to conceive again after giving birth resulted in the least risk of autism. Shorter and longer intervals resulted in risks that were up to 50% and 85% higher, respectively. About 5% to 9% of autism cases might be avoided by optimizing birth spacing.

Association between interpregnancy interval and hypertensive disorders of pregnancy: Effect modification by maternal age.

BACKGROUND: Short and long interpregnancy intervals (IPI) are associated with increased risk of hypertensive disorders of pregnancy, yet whether this association is modified by maternal age remains unclear. OBJECTIVES: To examine if the association between IPI and hypertensive disorders of pregnancy varies by maternal age at birth prior to IPI. METHODS: We conducted a population-based cohort study of all mothers who had their first two (n = 169 896) consecutive births in Western Australia (WA) between 1980 and 2015. We estimated the risk of preeclampsia and gestational hypertension for 6 to 60 months of IPI according to maternal age at birth prior to IPI (<20 years, 20-24, 25-29, 30-34 and ≥35 years). We modelled IPI using restricted cubic splines and reported adjusted relative risk (RRs) with 95% CI at 6, 12, 24, 36, 48 and 60 months, with 18 months as reference. RESULTS: The risk of preeclampsia was increased at longer IPIs (60 months) compared to 18 months for mothers 35 years or older (RR 2.19, 95% confidence interval (CI) 1.14, 4.18) and to a lesser extent for mothers 30- to 34 years old (RR 1.43, 95% CI 1.10, 1.84). Compared to 18 months, the risk of preeclampsia was lower at 12 months of IPI for mothers younger than 20 years (RR 0.74, 95% CI 0.57, 0.96), but not for mothers 35 years or older (RR 0.62, 95% CI 0.36, 1.07). There was insufficient evidence for increased risk of hypertensive disorders of pregnancy at shorter IPIs of <18 months for mothers of all ages. CONCLUSIONS: Our findings challenge the "one size fits all" recommendation for an optimal IPI, and a more tailored approach to family planning counselling may be required to improve health.

Community views on short birth interval in Northern Uganda: a participatory grounded theory.

BACKGROUND: Short birth interval is associated with adverse perinatal, maternal, and infant outcomes, although evidence on actionable factors underlying short birth interval remains limited. We explored women and community views on short birth intervals to inform potential solutions to promote a culturally safe child spacing in Northern Uganda. METHODS: Gendered fuzzy cognitive mapping sessions (n = 21), focus group discussions (n = 12), and an administered survey questionnaire (n = 255) generated evidence on short birth intervals. Deliberative dialogues with women, their communities, and service providers suggested locally relevant actions promote culturally safe child spacing. RESULTS: Women, men, and youth have clear understandings of the benefits of adequate child spacing. This knowledge is difficult to translate into practice as women are disempowered to exercise child spacing. Women who use contraceptives without their husbands' consent risk losing financial and social assets and are likely to be subject to intra-partner violence. Women were not comfortable with available contraceptive methods and reported experiencing well-recognized side effects. They reported anxiety about the impact of contraception on the health of their future children. This fear was fed by rumors in their communities about the effects of contraceptives on congenital diseases. The women and their communities suggested a home-based sensitization program focused on improving marital relationships (spousal communication, mutual understanding, male support, intra-partner violence) and knowledge and side-effects management of contraceptives. CONCLUSIONS: The economic context, gender power dynamics, inequality, gender bias in land tenure and ownership regulations, and the limited contraceptive supply reduce women's capacity to practice child spacing.

The evidence on what increases birth spacing remains limited. This study explored community views on influences on short birth interval to promote a culturally safe child spacing in Northern Uganda. A participatory research process began by collating perspectives of causes of short birth intervals through fuzzy cognitive mapping. Focus group discussions clarified concepts emerging from the fuzzy cognitive mapping exercise. Fieldworkers administered a household survey to quantify reproductive health outcomes. In deliberative dialogue sessions involving women and their communities, shared and discussed these results and suggested potential actions to promote culturally safe child spacing. Women, men, and youth showed clear understandings of the benefits of adequate child spacing. This knowledge is difficult to translate into practice, however, as women feel they are unable to exercise child spacing. Women who use contraceptives without their husbands' consent risk losing financial and social resources and are likely to face intra-partner violence. Women were not comfortable with contraceptive methods and reported experiencing side effects. The deliberative dialogues suggested a home-based sensitization program focused on improving marital relationships (spousal communication, mutual understanding, male support, intra-partner violence) and knowledge and side-effects management of contraceptives.

Pre-Pregnancy Intimate Partner Violence and Short Interbirth Interval: The Role of Insurance Status.

Short interbirth interval (IBI) has serious adverse health consequences, yet has an estimated prevalence of 35% in the United States. Similarly, intimate partner violence (IPV) around time of pregnancy, experienced by approximately 5% of women, is associated with increased risk of poor pregnancy outcomes. IPV might compromise women's decision-making, contributing to unintended pregnancy and short IBI. This study examines the relationship between pre-pregnancy IPV and short IBI, and whether insurance status moderates this relationship among multiparous women who responded to the 2009-2011 Pregnancy Risk Assessment Monitoring System survey (N = 13,675). Pre-pregnancy IPV (yes; no), insurance status (Private insurance; Medicaid/public insurance; no insurance), and short IBI (yes; no) were examined. Insurance status was identified as an effect modifier (p = .03), and maternal age, maternal and paternal education, marital status, and drinking alcohol were identified as potential confounders. Multiple logistic regression analysis stratified by insurance status provided adjusted odds ratios (aOR) with corresponding 95% confidence intervals (CI). Overall, 4.6% of women reported IPV before pregnancy, and 48% had a short IBI. When stratified by insurance status, the odds of short IBI was about 3 times higher among women with no insurance and women on Medicaid/public insurance who reported IPV compared to women who did not report IPV (aOR = 3.36, 95% CI = [1.02, 8.02], and aOR = 2.50, 95% CI = [1.04, 5.92], respectively). There was no observed significant difference in the likelihood of short IBI by experience of IPV among privately insured women. Findings from this study strengthen the evidence that women who experience IPV before pregnancy are significantly more likely to have short IBI compared to women who do not experience pre-pregnancy IPV. Furthermore, the odds of short IBI is highest among women experiencing pre-pregnancy IPV who are uninsured or on Medicaid/public insurance.

Factors influencing women's decisions about pregnancy spacing: Findings from a focus group discussion study.

OBJECTIVES: Very short interpregnancy intervals are associated with negative health outcomes for mothers and children, and pregnancies with very short interpregnancy intervals are more likely to be unintended than pregnancies that are more widely spaced. The objective of this study was to improve understanding of women's motivations regarding pregnancy spacing. METHODS: In 2017, we conducted 8 focus group discussions with 49 English- and Spanish-speaking postpartum women in central North Carolina. The groups explored participants' preferences for birth spacing and factors that influenced their decisions. We recorded, transcribed, and coded the discussions and analyzed these data for core themes. RESULTS: Participants' ideas about when and whether to have more children were fluid-some had specific ideas during pregnancy or after delivery that changed over time; others had no definite plans. The primary reason for close birth spacing was to promote their children's having a closer relationship. Reasons for wider spacing included recovery from the previous pregnancy, challenges related to having 2 babies concurrently, and desire to wait for more favorable life circumstances. Participants did not mention health risks to children of short interpregnancy intervals and said that no health care providers discussed these risks with them. They had mixed perspectives about whether this information would influence their own child-spacing preferences but agreed that it should be shared with women to promote informed decision-making. CONCLUSION: This study adds to limited research regarding the factors that women consider when determining pregnancy spacing. Better understanding of women's motivations can help inform counseling to help women achieve their desired pregnancy spacing.

Fertility intentions and recent births among US abortion patients.

OBJECTIVE: To examine fertility intentions among abortion patients and the potential of abortion for avoiding short birth intervals. STUDY DESIGN: We used national data from a sample of more than 8000 individuals obtaining abortions in the United States in 2014. We created a measure of fertility intentions based on prior births and responses to an item asking about future childbearing expectations. We identify respondents who reported having a birth in the last 12 months as at risk of a short birth interval. We used simple logistic regression to assess for differences in these measures according to key demographic variables. RESULTS: Most commonly, 39% of patients intended to have (more) children, with similar proportions wanting to delay a first birth (20%) or postpone a second or higher order birth (19%). Some 31% of abortion patients had completed childbearing; they had one or more prior births and did not want to have any more children. Similar proportions of respondents were not sure if they wanted to have children (16%) or did not want to have any children (15%). Among abortion patients who had children, 14% had had a birth in the prior year. We estimate that as many as 77,800 short birth intervals were averted in 2014 because individuals had access to abortion. CONCLUSIONS: These findings support the view that abortion allows individuals to plan and space their births according to their reproductive life plans and intentions. IMPLICATIONS: Access to abortion may help thousands of individuals in the United States avoid short birth intervals, potentially leading to improvements in maternal and child health.

Effect of birth spacing on the pelvic floor type Ⅰ and type Ⅱ fiber muscle strength of postpartum women with parities of two in different delivery modes / 中华妇产科杂志

Objective:To speculate the effect of birth spacing on the pelvic floor type Ⅰ and Ⅱ fiber muscle strength of postpartum women with parities of two in different delivery modes.Methods:Totally 2 361 parturients who were investigated in Xuzhou Central Hospital from June 2016 to December 2020 were included in the questionnaire, clinical examination and pelvic floor surface electromyography assessment. According to the interval years between two parities and the pelvic floor typeⅠ and Ⅱ fiber muscle strength under different modes of delivery, curve fitting function equation was performed using curve regression method. The accuracy of the equation was verified by the receiver operating characteristic curve and the maximum area under the curve, and calculating the relative error rate.Results:A total of 2 357 parturients were included in the study and were divided into 4 groups based on delivery modes, women with both normal vaginal delivery were assigned to group A (589 cases); women with a first vaginal delivery and a second cesarean section were assigned to group B (480 cases); women with both cesarean deliveries were assigned to group C (1 273 cases); women with a first cesarean section and a second vaginal delivery were assigned to group D (15 cases). All of the curve fitting results were quadratic curves, and the appropriate interval years were selected when the muscle strength of type Ⅰ muscle fibers was>35 μV and that of type Ⅱ muscle fibers was>40 μV: 6-8 years in the group A, 5-10 years in the group B, and 1-11 years in the group C. The peak values of the quadratic curve were as follows: 7-8 years in the group A, 7-8 years in the group B, and 6 years in the group C. The maximum area under the curve of the function equations were all>0.6 (all P<0.05), the average relative error rate was 4.909%. Conclusions:The pelvic floor function of postpartum women with parities of two increases firstly and then decreases over time, showing a quadratic curve shape. In order to protect the pelvic floor function, the appropriate interval of birth spacing is 6-8 years.
