Discussion: Targeting is making trade-offs

Predicting potential to benefit from an iron intervention: a randomized controlled trial of double-fortified salt in female Indian tea pluckers

OBJECTIVE

The present study examines characteristics of those who benefited from a dietary Fe intervention comprised of salt double-fortified with iodine and Fe (DFS).

DESIGN

Data from a randomized controlled trial were analysed to identify predictors of improved Fe status and resolution of Fe deficiency (serum ferritin (sFt) < 12 μg/l) and low body Fe (body Fe (BI) < 0·0 mg/kg) using non-parametric estimations and binomial regression models.

SETTING

A tea estate in West Bengal, India.

PARTICIPANTS

Female tea pluckers, aged 18-55 years.

RESULTS

Consuming DFS significantly (P = 0·01) predicted resolution of Fe deficiency (relative risk (RR) = 2·31) and of low BI (RR = 2·78) compared with consuming iodized salt. Baseline sFt (β = -0·32 (se 0·03), P < 0·001) and treatment group (β = 0·13 (se 0·03), P < 0·001) significantly predicted change in sFt. The interaction of baseline BI with treatment group (β = -0·11 (se 0·06), P = 0·08) predicted the change in BI. DFS did not significantly predict change in Hb and marginally predicted resolution of anaemia (Hb < 120 g/l).

CONCLUSIONS

Baseline Fe status, as assessed by sFt and BI, and consumption of DFS predict change in Fe status and resolution of Fe deficiency and low BI. Anaemia prevalence and Hb level, although simple and inexpensive to measure, may not be adequate to predict resolution of Fe deficiency in response to an intervention of DFS in similar populations with high prevalence of Fe deficiency and multiple nutritional causes of anaemia. These findings will guide appropriate targeting of future interventions.

Epidemiological assessment of food aid in the Bosnian conflict, 1994-97

Surveys in emergency settings are important for the accountability of food aid. Four household surveys conducted between 1994 and 1997 measured the performance of the Bosnia food aid programme, covering a random sample of clusters in Bosnia and Herzegovina and the Republica Srpska. The team calculated coverage, exclusion and inclusion errors, programme misses, and under-supply. Despite intended universal coverage from 1994-96, 15, 19, and 31 per cent, respectively, did not receive food across the three-year time frame. Households categorised as vulnerable were somewhat more likely to receive food. Programme misses were rare, whereas under-supply fell from 30 per cent in 1994 to four per cent in 1997, as the availability of other food increased. Extrapolation suggested that 61 per cent of the food distributed did not reach households. The programme introduced priority categories for targeting in 1997, yet nearly one-half of the highest priority households did not receive food. Incomplete coverage and weak targeting were related to political constraints.

Discrepancies in households and other stakeholders viewpoints on the food security experience: a gap to address

This paper reports results from a case study on household food insecurity needs and the interventions that address them. It aimed at comparing households' perceptions on food insecurity experience and vulnerability to those of other stakeholders: community workers, programme managers and representatives from donor agencies. Semi-structured interviews with 55 households and 59 other stakeholders were conducted. Content analysis was performed, using a framework encompassing food sufficiency, characterization of household food insecurity and vulnerability of households to food insecurity. Overall, the results draw attention to a gap between households and the other stakeholders, where the later do not seem always able to assess the realities of food-insecure households. Other areas of divergences include: characteristics of food insecurity, relative importance of various risk factors related to food insecurity and the effectiveness of the community assistance to enhance the households' ability to face food insecurity. These divergent perceptions may jeopardize the implementation of sustainable solutions to food insecurity. Training of stakeholders for a better assessment of households' experience and needs, and systematic evaluation of interventions, appear urgent and highly relevant for an adequate response to households' needs. Collaboration between all stakeholders should lead to knowledge sharing and advocacy for policies dedicated to poverty reduction.

Targeting of home-delivered meals programs to older adults in the United States

The Home-Delivered Meals Program (HDM) is an essential component of home-and community-based services available through the National Aging Service Network in the United States. It has the potential to help delay institutionalization and stem rising health care costs for older Americans; little is known, however, about the targeting practices used for HDM. A nationally representative telephone survey of state and local program providers showed that a variety of outreach measures were being employed, but challenges such as inadequate resources, waiting lists, rural delivery, and misconceptions about the program require resolution to ensure optimal service outcomes.
