Maternal and child social support and food availability in relation to child growth in four low- and middle-income countries.

Previous studies showed positive associations between specific types of social capital and child nutritional status. Our study examined whether improved food availability mediates the impact of maternal and child social support on child nutritional status in four low- and middle-income countries. We used data from the Young Lives cohort study, comprising 1,000 children aged 8 and 12 in Vietnam and Ethiopia, 1008 in India, and 714 in Peru. The outcome variables were the z-scores for height for age and body mass index (HAZ and BAZ, respectively). The causal mediation analysis framework was used. In Peru, above-median values of maternal social support and receiving child financial support were positively associated with HAZ at age 12. The level of maternal financial support was positively associated with BAZ among 12-year-old children in India. Peru was the only country where a positive association was found between food availability and maternal financial support among children aged 12. However, food availability did not mediate the effect of maternal financial support on HAZ at age 12. Strengthening social support to improve child nutritional status, especially by improving food availability, may not be a sufficient intervention in resource-poor settings because sources of support may lack sufficient food resources to share. However, more comprehensive measurements of social support and food security are necessary to better understand the mechanism of social support and child nutritional status.

Evaluating patient-reported outcome measures in Peru: a cross-sectional study of satisfaction and net promoter score using the 2016 EnSuSalud survey.

BACKGROUND: Patient-reported measures attempt to quantify the value health services provide to users. Satisfaction is a common summative measure, but often has limited utility in identifying poor quality care. We compared satisfaction and the net promoter score (NPS), which was developed to help businesses quantify consumer sentiment, in a nationally representative survey in Peru. We aimed to compare NPS and satisfaction as individual ratings of care, assess the relationship of patient-reported experience ratings to these outcome measures and consider the utility of these measures as indicators of facility performance based on reliability within facilities and capacity to discriminate between facilities. METHODS: We analysed the 2016 National Survey on User Satisfaction of Health Services, a cross-sectional outpatient exit survey. We assessed ratings by patient characteristics and compared the distributions of satisfaction and NPS categories. We tested the association of patient-reported experience measures with each outcome using multilevel ordinal logistic regression. We used intraclass correlation (ICC) from these models to predict minimum sample for reliable assessment and compared patient-reported experience measures in facilities with average satisfaction but below or above average NPS. RESULTS: 13 434 individuals rated services at 184 facilities. Satisfaction (74% satisfied) and NPS (17% reported at least 9 out of 10) were largely concordant within individuals but weakly correlated (0.37). Ratings varied by individual factors such as age and visit purpose. Most domains of patient-reported experience were associated with both outcomes. Adjusted ICC was higher for NPS (0.26 vs 0.11), requiring a minimum of 7 (vs 20) respondents for adequate reliability. Within the 70% of facilities classified as average based on satisfaction, NPS-based classification revealed systematic differences in patient-reported experience measures. CONCLUSION: While satisfaction and NPS were broadly similar at an individual level, this evidence suggests NPS may be useful for benchmarking facility performance as part of national efforts in Peru and throughout Latin America to identify deficits in health service quality.

Associations between maternal social capital and infant birth weight in three developing countries: a cross-sectional multilevel analysis of Young Lives data.

OBJECTIVE: To explore how three indicators of social capital (ie, group membership, social support and cognitive social capital and specific types within each type) are associated with infant birth weight. STUDY DESIGN AND SETTINGS: Cross-sectional analyses of the first wave of Young Lives Survey data collected in 2002 from India (Andhra Pradesh state), Peru and Vietnam. PARTICIPANTS: 807 mothers in India, 1528 mothers in Peru and 1706 mothers in Vietnam. OUTCOMES MEASURE: Infant birth weight was measured in grams. Participation in specific groups, receipt of social support from specific groups or individuals and perceptions of their community were measured for social capital indicators. Two-level random intercept linear regression models were fit separately by country (first level: individual and second level: community). RESULTS: Maternal group membership displayed a consistent positive association with infant birth weight across the three countries. There was no relationship with maternal cognitive social capital. Membership in a women's group was associated with infant birth weight consistently in all three countries (b=119.6, 95% CI 21.7 to 217.4 in India, b=133.4, 95% CI 40.9 to 225.9 in Peru, b=60.6, 95% CI 0.5 to 120.6 in Vietnam). However, membership in a political group in Peru was inversely associated with infant birth weight (b=-276.1, 95% CI -465.7 to -86.5). CONCLUSION: Although a higher level of social capital is associated with higher infant birth weight, specific types of social capital may have different associations with infant birth weight depending on the social, political or cultural specificity of the country. These results pave the way for additional research on the mechanisms through which social capital influences birth weight outcomes in each country.
