ABSTRACT: To investigate the effect of a two-component intervention to change hospital practice with regard to the timing of umbilical cord clamping.
A pre-/post-study design was used to measure the effect of a two-component intervention on mean time to clamp the umbilical cord. The study took place at Hospital Iquitos "César Garayar García" in Iquitos, Peru. A total of 224 women were recruited from the hospital labor room: 112 pre-intervention, from 18 May-3 June 2009, and 112 post-intervention, from 6-20 July 2009. The intervention consisted of 1) a "best practice" three-day training workshop on birthing, and 2) a hospital directive. All deliveries were observed and the time between delivery of the first shoulder and clamping of the umbilical cord was measured with a digital stopwatch.
The mean time between delivery and cord clamping before the intervention was 56.8 seconds (95% confidence interval [CI]: 51.0, 62.7). This increased to 169.8 seconds (95% CI: 153.8, 185.8) following the intervention. The difference in mean time to clamp remained significant in multivariate analyses (β adjusted = 113.2 seconds, 95% CI: 96.6, 129.9).
Hospital policy and practice can be successfully changed from early to delayed umbilical cord clamping using a simple, two-component intervention.

ABSTRACT: Growth faltering and nutritional deficiencies continue to be highly prevalent in infants and young children (IYC) living in low- and middle-income (LAMI) countries. There is increasing recognition that feeding behaviors and styles, particularly responsive feeding (RF), could influence acceptance of food and dietary intake and thus the growth of IYC. This paper presents the evolution of RF research and the strength of the evidence for RF on child undernutrition in LAMI countries. Multiple approaches were used to identify studies, including keyword searches in many databases, hand searches of retrieved articles, and consultation with experts in the field. Articles were included if they contained a RF exposure and child undernutrition outcome. In total, we identified 21 studies: 15 on child growth, 4 on dietary intake, 3 on disease, and 8 on eating behaviors. Most studies were conducted among children <36 mo of age and were published in the last 10 y. Cross-study comparisons were difficult due to multiple definitions of RF. One-half of the studies were observational with cross-sectional designs and few interventions were designed to isolate the effect of RF on child undernutrition. Overall, few studies have demonstrated a positive association between RF and child undernutrition, although there is promising evidence that positive caregiver verbalizations during feeding increase child acceptance of food. Recommendations for future research include consensus on the definition and measurement of RF, longitudinal studies that begin early in infancy, and randomized controlled trials that isolate the effect of RF on child undernutrition.

ABSTRACT: Prophylactic human papillomavirus (HPV) vaccines provide promise as a key component of future cervical cancer prevention programs in the Latin America and the Caribbean region. The successful introduction and acceptance of these vaccines will depend on a range of factors including awareness of cervical cancer as a problem, affordability of the vaccine, political will, competition with other vaccines, feasibility of vaccine delivery and acceptability of the vaccine among the range of groups who will influence uptake. While existing data about acceptability from Latin America and the Caribbean is scarce, it is clear that health policymakers, providers and the general public lack knowledge about HPV and cervical cancer. Furthermore, they would value more local epidemiologic data related to cervical cancer. Price is currently a major barrier to vaccine acceptability and a priority for advocacy. More research is required in Latin America and the Caribbean to determine what messages and strategies will work in these communities.

ABSTRACT: Process evaluation was used to examine the implementation of a randomized, controlled trial of an education intervention that improved infant growth in Trujillo, Peru. Health personnel delivered the multi-component intervention as part of usual care in the government health centers. Quantitative and qualitative methods were used to examine process indicators, which included the extent of delivery (dose), fidelity to intervention protocol, barriers to implementation and context. Results demonstrated that most intervention components were delivered at a level of 50-90% of expectations. Fidelity to intervention protocol, where measured, was lower (28-70% of expectations). However, when compared with existing nutrition education, as represented by the control centers, significant improvements were demonstrated. This included both improved delivery of existing educational activities as well as delivery of new intervention components to strengthen overall nutrition education. Barriers to, and facilitators of, implementation were explored with health personnel and helped to explain results. This study demonstrates the importance of examining actual versus planned implementation in order to improve our understanding of how interventions succeed. The information gained from this study will inform future evaluation designs, and lead to the development and implementation of more effective intervention programs for child health.

ABSTRACT: This article reports impact and cost results from a health facility-based nutrition education programme targeting children less than 2 years of age in Trujillo, Peru. Key elements of the programme included participative complementary feeding demonstrations, growth monitoring sessions and an accreditation process. Data were collected from six intervention and six control health facilities to measure utilization and costs associated with the intervention. To calculate the unit costs of services, these costs are allocated using activity-based costing. To measure the effects of the intervention, 338 children were followed through household surveys at regular intervals from birth until the age of 18 months. The intervention had a clear positive impact both on the use of nutrition-related services and on children's growth outcomes. Children in the intervention areas made 17.6 visits to health facilities in the first 18 months of life, compared with 14.1 visits for children in the control areas (P < 0.001). This pattern holds true for all socioeconomic groups. The intervention prevented 11.1 cases of stunting per 100 children. In multivariate logistic regression analysis, children in the intervention were 0.33 times as likely to be stunted as the controls (P = 0.002). The marginal cost of the intervention - including external costs, training, health education materials and extra travel and equipment - is 6.12 US dollars per child reached and 55.16 US dollars per case of stunting prevented. The estimated marginal cost of the intervention per death averted is 1952 US dollars.

ABSTRACT: Process evaluation was used to explain the success of a randomized, controlled trial of an educational intervention to improve the feeding behaviors of caregivers and the nutritional status of infants in Trujillo, Peru. Health personnel delivered a multicomponent intervention within the environment of usual care at government health centers. We created a model of the expected intervention pathway to successful outcomes. Process data were then collected on health center implementation of the intervention and caregiver reception to it. Using multivariate models, we found that variables of health center implementation, caregiver exposure, and caregiver message recall were all significant determinants in the pathway leading to improved feeding behaviors. These outcomes were consistent with our original intervention model. Further support for our model arose from the differences in caregiver reception between intervention and control centers. Process data allowed us to characterize the pathway through which an effective nutrition intervention operated. This study underscores the importance of including process evaluation, which will lead to the development and implementation of more effective nutrition interventions.

ABSTRACT: Formative research was conducted with 26 women and 16 adolescent girls to develop an education intervention through community kitchens (CK) in Lima, to increase their dietary iron intake and improve their iron status. A combination of qualitative research methods was used to explore perceptions about foods, nutrition, health, anemia and body image. The women recognized that there was a close association among eating well, "alimentarse bien", their health and prevention and treatment of anemia. They perceived that the nutritive value of a meal is determined primarily by its content of "nutritious" foods and by its being "balanced". Using this information the conceptual model of the education intervention was developed. The vulnerability of women to anemia was presented with the relationship between anemia and diet as the central focus. Feasible ways of achieving a nutritious diet were introduced to the community kitchens through promoting local heme iron sources and the consumption of beans with a vitamin C source. Animal source foods were amongst those considered to be nutritious and were "best buys" for iron content. CK searched for ways of assuring accessibility to these foods. The use of animal source foods in the community kitchen menus increased during the intervention.

ABSTRACT: Malnutrition is the underlying cause of half of child mortality. Many programmes attempt to remedy this issue but there is a lack of evidence on effective ways to decrease child malnutrition.
We did a cluster-randomised trial of an educational intervention in a poor periurban area (ie, shanty town) of Peru. Guided by formative research, the intervention aimed to enhance the quality and coverage of existing nutrition education and to introduce an accreditation system in six government health facilities compared with six control facilities. The primary outcome measure was growth that was measured by weight, length, and Z scores for weight-for-age and length-for-age at age 18 months. Main secondary outcomes were the percentage of children receiving recommended feeding practices and the 24-h dietary intake of energy, iron, and zinc from complementary food at ages 6, 9, 12, and 18 months. Analysis was by intention to treat.
We enrolled a birth cohort of 187 infants from the catchment areas of intervention centres and 190 from control areas. Caregivers in intervention areas were more likely to report receiving nutrition advice from the health service than were caregivers in control health facilities (16 [52%] of 31 vs 9 [24%] of 37, p=0.02). At 6 months more babies in intervention areas were fed nutrient-dense thick foods at lunch (a recommended complementary feeding practice) than were controls (48 [31%] of 157 vs 29 [20%] of 147; difference between groups 19 [11%], p=0.03). Fewer children in intervention areas failed to meet dietary requirements for energy (8 months: 30 [18%] of 170 vs 45 [27%] of 167, p=0.04; 12 months: 64 [38%] of 168 vs 82 [49%] of 167, p=0.043), iron (8 months: 155 [91%] of 170 vs 161 [96%] of 167, 9 months: 152 [93%] of 163 vs 165 [99%] of 166, p=0.047), and zinc (9 months: 125 [77%] of 163 vs 145 [87%] of 166, p=0.012) than did controls. Children in control areas were more likely to have stunted growth (ie, length for age less than 2 SD below the reference population median) at 18 months than children in intervention groups (26 [16%] of 165 vs 8 [5%] of 171; adjusted odds ratio 3.04 [95% CI 1.21-7.64]). Adjusted mean changes in weight gain, length gain, and Z scores were all significantly better in the intervention area than in the control area.
Improvement of nutrition education delivered through health services can decrease the prevalence of stunted growth in childhood in areas where access to food is not a limiting factor.

ABSTRACT: To understand the sociocultural environment, health systems' capacities, and policy processes related to cervical cancer and HPV vaccines in order to inform HPV vaccine introduction.
Mixed-method formative research using qualitative and quantitative data collection techniques. Participants included girls, parents, community leaders, health and education officials, and policymakers.
Respondents, including policymakers, generally supported HPV vaccine introduction, due partly to appreciation for the benefits of vaccination and the desire to prevent cancer. Community-level concerns regarding safety and quality of services will need to be addressed. The immunization system in Peru is strong and has capacity for including the HPV vaccine.
Formative research provides key insights to help shape an effective program for HPV vaccine introduction.
