Background

The rates of breastfeeding worldwide are slowly improving since 1996. Europe is still trailing behind the global breastfeeding incidence and prevalence rates. Thus, breastfeeding promotion, protection, prolongation and support have become an important challenge as breastfeeding sharply decreases in the first six months of life.

Objectives

The aim of this project is to determine, assess and identify the real impact of breastfeeding support networks in Murcia (Spain).

Methods

After searching unsuccessfully for a validated questionnaire, a specific one was developed and validated for measuring the impact of formal and informal support networks through five dimensions: satisfaction, consultation, experience, problems and support. The questionnaire was provided to 500 mothers with experience in breastfeeding, who brought their children to baby paediatricians between 2 June and 27 November 2014. Upon completion of the survey and fieldwork, a detailed statistical analysis was conducted.

Results

The degree of satisfaction perceived by the users of the services of support breastfeeding networks is remarkable. In addition, mothers who clarified their doubts and discussed their problems with health professionals and/or breastfeeding support networks were more likely to breastfeed for a longer duration compared to those who did not (p = 0.005). Furthermore, mothers who sought support in breastfeeding are more likely to breastfeed for more than 6 months (p < 0.0005).

Conclusion

Based on this information, we conclude that breastfeeding support networks have a positive influence in the duration of a women’s decision to breastfeed.  相似文献

If voters vote strategically, is it useful to offer them the possibility of expressing nuanced opinions, or would they always overstate the intensity of their preferences? For additive voting rules, say that a ballot is extremal if it is neither abstention-like nor can be expressed as a mixture of the available ballots. We give a sufficient condition for strategic equivalence: if two rules share the same set of extremal ballots (up to an homothetic transformation), they are strategically equivalent in large elections. This condition is also necessary for the strategic equivalence of positional rules. These results do not hold for small electorates.  相似文献

There is a gap in the Marriage and Family Therapy literature regarding clients', therapists', and family judges' theories of change in relational therapy for family violence. We conducted in-depth interviews with eleven court-referred families, their therapists, and two family judges in Bogota, Colombia. Interviews focused on their expectations of therapy outcomes, their understanding of change, and their evaluation of individual and relational therapy outcomes. We followed a grounded theory approach to data analysis. Analyses showed that therapists, family judges, and clients hold different expectations and theories regarding therapeutic change. Findings are discussed based on existing research on clients' and therapists' ideas about change. Implications for future research and practice are presented.  相似文献

This study of 114 workers in the hydrocarbon industry was conducted to identify the relationship between stress and musculoskeletal discomfort, and to view the roles played by such factors as age, schooling, obesity, workplace and job seniority. All factors except seniority were found to affect the presence of musculoskeletal discomfort in some area of the body.  相似文献

The paper describes the application of a simulation based ergonomic evaluation. Within a pilot project, the algorithms of the screening method of the European Assembly Worksheet were transferred into an existing digital human model. Movement data was recorded with an especially developed hybrid Motion Capturing system. A prototype of the system was built and is currently being tested at the Volkswagen Group. First results showed the feasibility of the simulation based ergonomic evaluation with Motion Capturing.  相似文献

This article details one teacher preparation course centering Latin American Testimonio narratives of struggle/survival amid structural oppression for use in secondary curriculum. As our class of predominantly Latina/o students and two Latina instructors engaged Testimonio pedagogy, we fashioned a hopeful alternative to our own experiences of intergenerational oppression. While research indicates that the experiences and histories of pre-service Teachers of Color lend pedagogical strength and critical consciousness to teacher education, three Latina pre-service students highlight the ways in which Testimonio became more than a pedagogical approach. Testimonio’s collectivity, resistance, hope, and assertions of voice and dignity moved through them not as educators first but as (great-grand)daughters of oppressed though still-resilient People(s). Testimonio emboldened these Latina pre-service educators to recognize and validate their own inherited multiliteracies, (re)claim their connectedness to land, and articulate their visions for more equitable schooling. This work advances research into the essentiality of engaging race and ethnicity in K-12 and teacher education curriculum and pedagogy.  相似文献
