“…The 14 studies included four RCTs [30,37,41,42], seven CBAs [32,38,39,43,46-48] and three ITSs [18,44,49]. Eleven of the studies were from the United States [18,32,38,40-49] with nine of these focussed on the WIC program [18,32,38,40,42-48].…”

“…These larger CBA studies were part of a National WIC evaluation in the 1980s. There were also four smaller CBA studies [32,38,43,48], involving 101–702 participants, which evaluated different aspects of the WIC program. Of the five non-WIC studies, there were three RCTs: one of supermarket price discounts for 1104 regular adult shoppers in New Zealand [30], one of subsidised fruit juice for 190 pregnant women in the UK [37] and another of a F&V subsidy for 40 overweight women in the USA [41].…”

“…The interventions included the standard WIC program [18,42,44,46-48] or enhancements to the WIC program with either an additional six months of postnatal supplements [38,43] or $US10 F&V per week [32]. The standard WIC program includes monthly food vouchers, nutrition education and healthcare referrals at WIC clinics.…”

Food subsidy programs and the health and nutritional status of disadvantaged families in high income countries: a systematic review

et al. 2012

BackgroundLess healthy diets are common in high income countries, although proportionally higher in those of low socio-economic status. Food subsidy programs are one strategy to promote healthy nutrition and to reduce socio-economic inequalities in health. This review summarises the evidence for the health and nutritional impacts of food subsidy programs among disadvantaged families from high income countries.MethodsRelevant studies reporting dietary intake or health outcomes were identified through systematic searching of electronic databases. Cochrane Public Health Group guidelines informed study selection and interpretation. A narrative synthesis was undertaken due to the limited number of studies and heterogeneity of study design and outcomes.ResultsFourteen studies were included, with most reporting on the Special Supplemental Nutrition Program for Women, Infants and Children in the USA. Food subsidy program participants, mostly pregnant or postnatal women, were shown to have 10–20% increased intake of targeted foods or nutrients. Evidence for the effectiveness of these programs for men or children was lacking. The main health outcome observed was a small but clinically relevant increase in mean birthweight (23–29g) in the two higher quality WIC studies.ConclusionsLimited high quality evidence of the impacts of food subsidy programs on the health and nutrition of adults and children in high income countries was identified. The improved intake of targeted nutrients and foods, such as fruit and vegetables, could potentially reduce the rate of non-communicable diseases in adults, if the changes in diet are sustained. Associated improvements in perinatal outcomes were limited and most evident in women who smoked during pregnancy. Thus, food subsidy programs for pregnant women and children should aim to focus on improving nutritional status in the longer term. Further prospective studies and economic analyses are needed to confirm the health benefits and justify the investment in food subsidy programs.

In this work, pyridoxine (vitamin B6) was determined by the square wave voltammetry at copper‐poly(1,8‐diaminonaphthalene)/graphene modified glassy carbon electrode. The composite electrodes were fabricated with two steps. First, poly(1,8‐diaminonaphthalene) is electrodeposited onto graphene/glassy carbon electrodes with a potential cycling technique. Then, copper ions are adsorbed onto the poly(1,8‐diaminonaphthalene)/graphene modified glassy carbon electrode due to the immersion of the polymeric modified electrode in an aqueous copper (II) solution. The characterizations of synthesized materials have shown the role of graphene in facilitating the electron transfer and the remarkably electrocatalytic ability of copper for pyridoxine oxidation on the electrode surface. In 0.1 M phosphate buffer solution (pH 7.4), the peak current of square wave voltammograms of pyridoxine increased linearly with their concentration in the ranges between 0.58 and 24.51 μM with the limit of detection of 0.3 μM. The proposed electrodes showed excellent reproducibility and stability.
