13. Sguassero 2012: details of interventions (as reported in systematic review).

Review ID	Sguassero 2012
Types of interventions considered	Supplementary feeding was defined as the provision of extra food to children or families beyond the normal rations of their home diets. The intervention had to be community based in that young children could consume the supplementary food at home, at a supervised feeding centre or at other places adapted for this purpose such as healthcare centres and crèches. Supplementary feeding could comprise: meals (local or imported foods) drinks (juices or milk) snacks (including both food and milk snacks)
Details regarding the interventions	Multi‐mixture Intervention: multi‐mixture 10 g/day comprising (per 100 g preparation) 47.5% wheat flour; 47.5% cornmeal; 4% melon seed powder, sesame, gourd and peanut; 0.5% cassava leaf powder and 0.5% eggshells (energy = 390 kcal (per 100 g), ashes = 2.7 g, lipids = 5.2 g, proteins = 11.7 g, CHO = 74.2 g, fibres = 6.2 g, iron = 8 mg, calcium = 357 mg, magnesium = 235 mg, potassium = 677 mg, phosphorus = 570 mg, sodium = 7 mg) Control: cassava flour 5 g similar to mixture in colour and thickness of grains (energy (centesimal composition) = 336.8 calories, CHO = 81.1 g, proteins = 2.2 g, lipids = 0.05 g, calcium = 21 mg, phosphorus = 105 mg and 0.8 mg iron per 100 g preparation) Duration: 2 months Multi‐mixture Intervention: 2 tablespoons of multi‐mixture comprising 80% wheat flour, 10% cassava leaf powder and 10% eggs shells during the child meals. Ingredients cooked over low heat for 5–10 minutes and then the heat was stifled for their homogenisation Control: no supplementation Duration: 10 months Yoghurt Intervention: 125 g/cup daily serving (protein = 3.8 g, calcium = 150 mg, vitamin B2 = 0.19 mg) Control: no supplementation Duration: 9 months (Monday–Friday) High‐energy protein drink Intervention: atole beverage (energy = 90.5 kcal, protein = 6.3 g/100 mL + micronutrients) Control: fresco, a low‐energy, non‐protein drink (energy = 33 kcal/100 mL + micronutrients); atole differed in name, appearance and taste Duration: on‐demand (twice a day, all week) Snacks Intervention: twice‐a‐day snacks (rice, rice flour, wheat flour, bread, cassava, potatoes, sweet potatoes, coconut milk, refined sugar, brown sugar and edible oil), given 6 days/week for 90 days (on average, energy = 400 kcal (energy content varied between 187 and 216 kcal), protein = 5 g (protein content varied between 1.8 g and 4.4 g)) Control: no food supplementation Duration: 3 months (90 days) Condensed milk + micronutrient tablet Intervention: 11 teaspoons of condensed milk (energy = 250 kcal, protein = 6 g/ration) + dissolved tablet of micronutrients Control: 11 teaspoons of skimmed milk (energy = 20 kcal, protein = 1.35 g/ration) + dissolved tablet of micronutrients Duration: 12 months (twice a day for 6 days/week) Milk‐based formula Intervention: milk‐based formula 1 kg/week (energy = 525 kcal, protein = 14 g/100 g). In addition, 0.9 kg cornmeal and skimmed‐milk powder were given to the family Control: no food supplementation Duration: 12 months Porridge Intervention: cereal‐based, precooked porridge enriched with micronutrients, which had to be mixed with boiled water for hygienic preparation (per 100 g dry porridge, energy = 410 kcal, protein = 9 g, lipids = 10 g, CHO = 67 g + micronutrients). Introduction was progressive: 25 g dry supplement in 75 mL water/meal (i.e. 103 kcal in 100 g from 4–5 months) and 50 g supplement and 135 mL water/meal (i.e. 205 kcal in 185 g from 5–7 months). No food was given for other family members Control: no supplementation Duration: 3 months
