ABSTRACT There is good evidence that lactational amenorrhea (LAM) is an effective method of fertility regulation during the first 6 months postpartum, provided no other food is given to the baby and the mother remains amenorrheic. However, although breast-feeding is strongly promoted in many maternity hospitals that also run postpartum family planning programs, LAM is rarely included among the contraceptive options being offered. This paper presents the results of an operational study which compared the prevalence of contraceptive use and the cumulative pregnancy rate at 12-months postpartum among 350 women observed before and 348 women studied after introducing LAM as an alternative contraceptive option offered to women following delivery at the Instituto Materno Infantil de Pernambuco (IMIP), in Recife, Brazil. The percentage of women not using any contraceptive method was significantly lower (p<0.0001) after the intervention (7.4%) than before (17.7%). This difference remained statistically significant after controlling for age, number of living children, marital status and years of schooling. The proportion pregnant one year postpartum was also significantly lower (p<0.0001) after the introduction of LAM (7.4%) than before (14.3%), but the difference was no longer significant after controlling for the same variables. It is concluded that LAM is a useful addition to family planning postpartum programs.

    ABSTRACT: OBJECTIVES: to assess the effect of lactation introduction and amenorrhea as a contraceptive method on child health in a post-delivery program. METHODS: operational survey assessing total and exclusive breast feeding and some health indicators of children up to one year old, before and after the LAM program as a method offered to women after delivery in addition to education on breast feeding and family planning. Six hundred and ninety eight women who had their prenatal care in the Institution were broken into two groups: Group A receiving assistance before and B receiving assistance following the program. Statistical analysis used the Chi-Square test, survival analysis and Cox's logistic regression. RESULTS: Group A had 85.6% of morbid episodes up to 12 months and Group B 71.2%. The number of hospital admissions more than doubled for children in Group A. Weight and height of the children at twelve months old and accumulated rates of total breast feeding were significantly higher in Group B. CONCLUSIONS: this educational program is associated to better child health results and can be used in other institutions for its beneficial impact on child healthcare.

    ABSTRACT: Globally, unmet need for postpartum family planning remains high, while immunization services are among the most wide-reaching and equitable interventions. Given overlapping time frames, integrating these services provides an opportunity to leverage existing health visits to offer women more comprehensive services. From March through November 2012, Liberia's government, with support from the Maternal and Child Health Integrated Program (MCHIP), piloted an integrated family planning and immunization model at 10 health facilities in Bong and Lofa counties. Vaccinators provided mothers bringing infants for routine immunization with targeted family planning and immunization messages and same-day referrals to co-located family planning services. In February 2013, we compared service statistics for family planning and immunization during the pilot against the previous year's statistics. We also conducted in-depth interviews with service providers and other personnel and focus group discussions with clients. Results showed that referral acceptance across the facilities varied from 10% to 45% per month, on average. Over 80% of referral acceptors completed the family planning visit that day, of whom over 90% accepted a contraceptive method that day. The total number of new contraceptive users at participating facilities increased by 73% in Bong and by 90% in Lofa. Women referred from immunization who accepted family planning that day accounted for 44% and 34% of total new contraceptive users in Bong and Lofa, respectively. In Lofa, pilot sites administered 35% more Penta 1 and 21% more Penta 3 doses during the pilot period compared with the same period of the previous year, while Penta 1 and Penta 3 administration decreased in non-pilot facilities. In Bong, there was little difference in the number of Penta 1 and Penta 3 doses administered between pilot and non-pilot facilities. In both counties, Penta 1 to Penta 3 dropout rates increased at pilot sites but not in non-pilot facilities, possibly due to higher than average background dropout rates at pilot sites prior to the intervention in Lofa and the disproportionate effect of data from 1 large facility in Bong. The project provided considerable basic support to assess this proof of concept. However, results suggest that introducing a simple model that is minimally disruptive to existing immunization service delivery can facilitate integration. The model is currently being scaled-up to other counties in Liberia, which could potentially contribute to increased postpartum contraceptive uptake, leading to longer birth intervals and improved health outcomes for children and mothers. © Cooper et al.

    ABSTRACT: The past decade has witnessed increasing global attention and political support for maternal, newborn and child health. Despite this increased attention, actual progress has been slow and sporadic: coverage of key maternal and newborn health interventions remains low and there are wide disparities in access to care, within and across countries. Strategies for improving maternal and newborn health are closely linked, and can be delivered most effectively through a continuum of care approach. While these interventions are largely known, there is little information on which interventions have a positive health impact for both women and newborns. This supplement identifies the interventions during the preconception, pregnancy, intrapartum and postnatal periods found to have a positive, synergistic effect on maternal and neonatal outcomes. These interventions are then grouped into packages of care for delivery at the community, health center or hospital levels.
