Time trend in breast-feeding in the city of Rio de Janeiro, Southeastern Brazil: 1996-2006

Maternity leave and exclusive breastfeeding

OBJECTIVE

To analyze the association between maternity leave and exclusive breastfeeding and to estimate the prevalence of exclusive breastfeeding in children under six months of life.

METHODS

Cross-sectional study, with mothers of children under six months of life, attended in primary health care units with Breast Milk Collection Services in the municipality of Rio de Janeiro, Brazil, in 2013 (n = 429). We analyzed characteristics concerning: maternal sociodemographic aspects, household, prenatal care, childbirth, maternal lifestyle, the child, health care, and infant feeding. Adjusted prevalence ratios (APR) were obtained by Poisson regression with robust variance according to hierarchical approach, and we kept in the final model variables that were associated (p ≤ 0.05) with exclusive breastfeeding (outcome).

RESULTS

Among the interviewed mothers, 23.1% were on maternity leave and 17.2% were working. The prevalence of exclusive breastfeeding was 50.1%. The maternal work with maternity leave was associated with higher prevalence of the outcome (APR = 1.91; 95%CI 1.32-2.78), compared with mothers who worked without maternity leave.

CONCLUSIONS

Maternity leave has contributed to the practice of exclusive breastfeeding for children under six months of life, which indicates the importance of this benefit in protecting exclusive breastfeeding for women inserted in the formal labor market.

[Breastfeeding-Friendly Primary Care Unit Initiative and the relationship with exclusive breastfeeding]

OBJECTIVE

To analyze the prevalence of exclusive breastfeeding and the association with the Breastfeeding-Friendly Primary Care Unit Initiative.

METHODS

Cross-sectional study, whose data source were research on feeding behaviors in the first year of life conducted in the vaccination campaigns of 2003 and 2006, at the municipality of Barra Mansa, RJ, Southeastern Brazil. For the purposes of this study, infants under six months old, accounting for a total of 589 children in 2003 and 707 children in 2006, were selected. To verify the relationship between being followed-up by Breastfeeding-Friendly Primary Care Unit Initiative units and exclusive breastfeeding practice, only data from the 2006 inquiry was used. Variables that in the bivariate analysis were associated (p-value ≤ 0.20) with the outcome (exclusive breastfeeding practice) were selected for multivariate analysis. Prevalence ratios (PR) of exclusive breastfeeding were obtained by Poisson Regression with robust variance through a hierarchical model. The final model included the variables that reached p-value ≤ 0.05.

RESULTS

The prevalence of exclusive breastfeeding increased from 30.2% in 2003 to 46.7% in 2006. Multivariate analysis showed that mother's low education level reduced exclusive breastfeeding practice by 20.0% (PR = 0.798; 95%CI 0.684;0.931), cesarean delivery by 16.0% (PR = 0.838; 95%CI 0.719;0.976), and pacifier use by 41.0% (PR = 0.589; 95%CI 0.495;0.701). In the multiple analysis, each day of the infant's life reduced exclusive breastfeeding prevalence by 1.0% (PR = 0.992; 95%CI 0.991;0.994). Being followed-up by Breastfeeding-Friendly Primary Care Initiative units increased exclusive breastfeeding by 19.0% (PR = 1.193; 95%CI 1.020;1.395).

CONCLUSIONS

Breastfeeding-Friendly Primary Care Unit Initiative contributed to the practice of exclusive breastfeeding and to the advice for pregnant women and nursing mothers when implemented in the primary health care network.

Physical violence between intimate partners during pregnancy and postpartum: a prediction model for use in primary health care facilities

This article offers a simple predictive model of physical intimate partner violence (PIPV) to be used by primary health care (PHC) professionals. The sample comprised 811 mothers of children <5 months old attending PHC facilities in Rio de Janeiro, Brazil. A multinomial logit model was used. Measured by the Revised Conflict Tactics Scales, PIPV was classified in three levels (absence, at least one episode during pregnancy or postpartum, and presence in both periods). Socio-economic, demographic and life style variables were considered as potential predictors. Maternal age <20 years, an education of <8 years of schooling, raising >2 children under 5, tobacco smoking, alcohol misuse and illicit drug use by the mother and/or partner, and perception of baby's ill-health were identified as predictors of PIPV. The model-projected prevalence of PIPV for pregnancy and/or postpartum was just 10.1% in the absence of these characteristics, whereas this increased to 96.4% when all the seven characteristics were present. Child, maternal and family characteristics greatly increase the likelihood of PIPV and could be used together as screening indicators.
