Abstract: Using panel data from Ethiopia covering 1994–1997, we estimate the impact of prime age adult mortality on household composition, household expenditures and dietary diversity. We employed propensity score matching with a difference-in-difference estimator to control for endogeneity of mortality to the outcomes of interest. Households losing a productive adult did not replenish the lost labor, regardless of economic status, sex or status of the deceased adult. With the exception of non-poor households, adult mortality resulted in increased dependency ratios, but did not adversely affect households’ expenditure patterns (total, food and non-food expenditures) regardless of the sex and position of the deceased and the economic status of the households. Although food expenditures were protected, a decline in dietary diversity, especially among the poorest households, reflected increased nutrition insecurity associated with adult mortality.

With the efficacy of antiretroviral therapy, people living with HIV (PLWH) are surviving longer and improving their health related quality of life (HRQol) has become an important long-term HIV treatment and management indicator. HRQol has been associated with various factors, including food insecurity (FI). The objective of this prospective study was to examine the association between FI and dietary diversity (HDDS) and HRQol among PLWH in Accra, Ghana. We recruited 152 PLWH from the HIV clinics of six district hospitals Accra, Ghana and utilized a prospective cohort study design with data collection at baseline, three and six months after recruitment for this study. Participants completed questionnaires measuring HRQol, FI and HDDS. Repeated measures ANOVA was used to analyze the associations between FI and HRQol as well as HDDS and HRQol separately and then together. Being food secure [0.035 (95% CI = 0.005, 0.065)] and having a high dietary diversity score [0.029 (95% CI = 0.004, 0.053)] were independently associated with an improvement in quality of life scores over time after adjusting for other covariates and each other. Interventions to improve dietary diversity and food security among PLWH have the potential to improve nutritional status as well as HRQol. [ABSTRACT FROM AUTHOR]

Objective: To explore the effect of seasonality on fruit and vegetable availability and prices across three outlet types (farmers' markets, roadside stands and conventional supermarkets).Design: Cross-sectional survey of geographically clustered supermarkets, farmers' markets and roadside stands. Enumerators recorded the availability and lowest price for eleven fruits and eighteen vegetables in each season of 2011.Setting: Price data were collected at retail outlets located in central and eastern North Carolina.Subjects: The sample consisted of thirty-three supermarkets, thirty-four farmers' markets and twenty-three roadside stands.Results: Outside the local harvest season, the availability of many fruits and vegetables was substantially lower at farmers' markets and roadside stands compared with supermarkets. Given sufficient availability, some items were significantly cheaper (P<0·05) at direct retail outlets in the peak season (e.g. cantaloupe cost 36·0 % less at roadside stands than supermarkets), while others were significantly more expensive (e.g. carrots cost 137·9 % more at farmers' markets than supermarkets). Although small samples limited statistical power in many non-peak comparisons, these results also showed some differences by item: two-thirds of fruits were cheaper at one or both direct outlets in the spring and autumn, whereas five of eighteen vegetables cost more at direct retail year-round.Conclusions: Commonly consumed fruits and vegetables were more widely available at supermarkets in central and eastern North Carolina than at direct retail outlets, in each season. Contingent on item availability, price competitiveness of the direct retail outlets varied by fruit and vegetable. For many items, the outlets compete on price in more than one season.

Objective: To compare the impact on child diet and growth of a multisectoral community intervention v. nutrition education and livestock management training alone.Design: Longitudinal community-based randomized trial involving three groups of villages assigned to receive: (i) Full Package community development activities, delivered via women's groups; (ii) livestock training and nutrition education alone (Partial Package); or (iii) no intervention (Control). Household surveys, child growth monitoring, child and household diet quality measures (diet diversity (DD), animal-source food (ASF) consumption) were collected at five visits over 36 months. Mixed-effect linear regression and Poisson models used survey round, treatment group and group-by-round interaction to predict outcomes of interest, adjusted for household- and child-specific characteristics.Setting: Banke, Nepal.Participants: Households (n 974) with children aged 1-60 months (n 1333).Results: Children in Full Package households had better endline anthropometry (weight-for-age, weight-for-height, mid-upper-arm-circumference Z-scores), DD, and more consumption of ASF, after adjusting for household- and child-specific characteristics. By endline, compared with Partial Package or Control groups, Full Package households demonstrated preferential child feeding practices and had significantly more improvement in household wealth and hygiene habits.Conclusions: In this longitudinal study, a comprehensive multisectoral intervention was more successful in improving key growth indicators as well as diet quality in young children. Provision of training in livestock management and nutrition education alone had limited effect on these outcomes. Although more time-consuming and costly to administer, incorporating nutrition training with community social capital development was associated with better child growth and nutrition outcomes than isolated training programmes alone.

This paper compares a qualitative and a quantitative (Rasch) method of item assessment for developing the content of a food insecurity scale for Bangladesh. Data are derived from the Bangladesh Food Insecurity Measurement and Validation Study, in which researchers collected 2 rounds of ethnographic information and 3 rounds of conventional household survey data between 2001 and 2003. The qualitative method of scale development relied on content experts and respondents themselves to evaluate household food insecurity items generated through ethnographic research. The quantitative method applied the Rasch model to assess the fit of the same items using representative survey data. The Rasch model was then used to test for differential item functioning (DIF) across diverse demographic and geographic subgroups. The qualitative assessment flagged and discarded 10 items, leaving 13. The Rasch assessment of infit and outfit flagged 3 items, and the Rasch DIF test discarded another 10 items, leaving a total of 10 items in the Rasch-derived scale. The 2 scales contained 8 of the same items. The qualitatively and quantitatively derived scales were highly correlated (r = 0.96, P < 0.01), and the 2 methods located 90% of households in the same food insecurity tercile. This convergence lends added confidence to the use of either scale for identifying food-insecure households in different regions of Bangladesh. Multiple methods should continue to be applied in a systematic and transparent way to lend additional credence to the results when they converge and to pinpoint directions for further clarification where they do not.
