          Abstract

          Resumen Objetivo: Evaluar la prevalencia de fallo en la regulación de la fertilidad posparto y la asociación con otros factores en un municipio colombiano (2017). Método: Estudio observacional de corte transversal con 148 mujeres. Se aplicó un muestreo no aleatorio para incluir mujeres que hubieran tenido un parto en los últimos 5 años. Se calcularon la prevalencia y las razones de prevalencia. Se exploró la asociación con la prueba χ2 o la prueba exacta de Fisher bajo una significancia estadística de 0,05. Resultados: Se encontró una prevalencia de fallo de la regulación de la fertilidad posparto del 40,5%. La prevalencia se asoció con ejercer oficios del hogar, tener uno o dos hijos, no planificar o no acceder a métodos de planificación y haber tenido un embarazo con periodo intergenésico menor de 2 años (p < 0,05). Conclusiones: Es necesario implementar estrategias para identificar barreras de acceso a la planificación, impactando en el espaciamiento entre embarazos y el acceso a los servicios. Lo anterior para generar múltiples beneficios para la madre, su hijo/a, el sistema de salud y la sociedad.

          Abstract Objective: To evaluate the prevalence of regulated postpartum fertility failure and possible associated factors in a Colombian municipality (2017). Method: Cross-sectional observational study of 148 women. A non-random sampling method was used to include women who had given birth to a child in the last five years. Prevalence and prevalence ratios were calculated. Associations were examined at 0.05 statistical significance using χ2 test or Fisher’s exact test. Results: The prevalence of postpartum fertility failure was found to be 40.5%. The prevalence was associated with household work, having one or two children, not planning, or not having access to planning methods, and having a pregnancy with an interval between pregnancies of less than 2 years (p < 0.05). Conclusions: It is necessary to implement strategies to identify barriers to access to planning, which have an impact on the spacing between pregnancies and access to services. This will have multiple benefits for mother, child, health system and society.

          Effects of preceding birth intervals on neonatal, infant and under-five years mortality and nutritional status in developing countries: evidence from the demographic and health surveys.

          This paper examines the association between birth intervals and infant and child mortality and nutritional status. Repeated analysis of retrospective survey data from the Demographic and Health Surveys (DHS) program from 17 developing countries collected between 1990 and 1997 were used to examine these relationships. The key independent variable is the length of the preceding birth interval measured as the number of months between the birth of the child under study (index child) and the immediately preceding birth to the mother, if any. Both bivariate and multivariate designs were employed. Several child and mother-specific variables were used in the multivariate analyses in order to control for potential bias from confounding factors. Adjusted odds ratios were calculated to estimate relative risk. For neonatal mortality and infant mortality, the risk of dying decreases with increasing birth interval lengths up to 36 months, at which point the risk plateaus. For child mortality, the analysis indicates that the longer the birth interval, the lower the risk, even for intervals of 48 months or more. The relationship between chronic malnutrition and birth spacing is statistically significant in 6 of the 14 surveys with anthropometric data and between general malnutrition and birth spacing in 5 surveys. However, there is a clear pattern of increasing chronic and general undernutrition as the birth interval is shorter, as indicated by the averages of the adjusted odds ratios for all 14 countries. Considering both the increased risk of mortality and undernutrition for a birth earlier than 36 months and the great number of births that occur with such short intervals, the author recommends that mothers space births at least 36 months. However, the tendency for increased risk of neonatal mortality for births with intervals of 60 or more months leads the author to conclude that the optimal birth interval is between 36 and 59 months. This information can be used by health care providers to counsel women on the benefits of birth spacing.

            Effects of birth spacing on maternal, perinatal, infant, and child health: a systematic review of causal mechanisms.

            This systematic review of 58 observational studies identified hypothetical causal mechanisms explaining the effects of short and long intervals between pregnancies on maternal, perinatal, infant, and child health, and critically examined the scientific evidence for each causal mechanism hypothesized. The following hypothetical causal mechanisms for explaining the association between short intervals and adverse outcomes were identified: maternal nutritional depletion, folate depletion, cervical insufficiency, vertical transmission of infections, suboptimal lactation related to breastfeeding-pregnancy overlap, sibling competition, transmission of infectious diseases among siblings, incomplete healing of uterine scar from previous cesarean delivery, and abnormal remodeling of endometrial blood vessels. Women's physiological regression is the only hypothetical causal mechanism that has been proposed to explain the association between long intervals and adverse outcomes. We found growing evidence supporting most of these hypotheses.

              A systematic review and meta-analysis of postpartum contraceptive use among women in low- and middle-income countries

              Background Short birth intervals increase risk for adverse maternal and infant outcomes including preterm birth, low birth weight (LBW), and infant mortality. Although postpartum family planning (PPFP) is an increasingly high priority for many countries, uptake and need for PPFP varies in low- and middle-income countries (LMIC). We performed a systematic review and meta-analysis to characterize postpartum contraceptive use, and predictors and barriers to use, among postpartum women in LMIC. Methods PubMed, EMBASE, CINAHL, PsycINFO, Scopus, Web of Science, and Global Health databases were searched for articles and abstracts published between January 1997 and May 2018. Studies with data on contraceptive uptake through 12 months postpartum in low- and middle-income countries were included. We used random-effects models to compute pooled estimates and confidence intervals of modern contraceptive prevalence rates (mCPR), fertility intentions (birth spacing and birth limiting), and unmet need for contraception in the postpartum period. Results Among 669 studies identified, 90 were selected for full-text review, and 35 met inclusion criteria. The majority of studies were from East Africa, West Africa, and South Asia/South East Asia. The overall pooled mCPR during the postpartum period across all regions was 41.2% (95% CI: 15.7–69.1%), with lower pooled mCPR in West Africa (36.3%; 95% CI: 27.0–45.5%). The pooled prevalence of unmet need was 48.5% (95% CI: 19.1–78.0%) across all regions, and highest in South Asia/South East Asia (59.4, 95% CI: 53.4–65.4%). Perceptions of low pregnancy risk due to breastfeeding and postpartum amenorrhea were commonly associated with lack of contraceptive use and use of male condoms, withdrawal, and abstinence. Women who were not using contraception were also less likely to utilize maternal and child health (MCH) services and reside in urban settings, and be more likely to have a fear of method side effects and receive inadequate FP counseling. In contrast, women who received FP counseling in antenatal and/or postnatal care were more likely to use PPFP. Conclusions PPFP use is low and unmet need for contraception following pregnancy in LMIC is high. Tailored counseling approaches may help overcome misconceptions and meet heterogeneous needs for PPFP.
