Universal salt iodization (USI) is the main global strategy to eliminate iodine deficiency. Regulation of USI programs often omits salt used in processed foods, despite their increasing contribution to salt intake. In West Africa, bouillon seasoning is a widely consumed source of salt and is therefore relevant to USI effectiveness.

Many nutrient biomarkers are altered by inflammation. We calculated adjustment factors for retinol and ferritin by using meta-analyses of studies containing the respective biomarker and 2 acute phase proteins in serum, C-reactive protein (CRP), and α1-acid glycoprotein (AGP). With the use of CRP and AGP we identified 4 groups in each study: reference (CRP ≤5 mg/L, AGP ≤1 g/L), incubation (CRP >5 mg/L, AGP ≤1 g/L), early convalescence (CRP >5 mg/L, AGP >1 g/L), and late convalescence (CRP ≤5 mg/L, AGP >1 g/L).

Anaemia is prevalent in South East Asia and Fe deficiency (ID) is considered to be the main cause, but the role of subclinical inflammation in the aetiology is uncertain. In the present study, we determined the influence of inflammation on the biomarkers of Fe status in women and children, and herein, we discuss the proportion of anaemia associated with ID. As part of the 2006 Lao People's Democratic Republic (The Lao PDR) National Nutrition Survey, blood collected from 482 young children and 816 non-pregnant women was analysed.

A study was carried out to determine whether thiamine deficiency in northeast Thailand is linked with parasitic infection. We assessed the thiamine status and tested for parasitic infections in 231 children between 6 and 12 years of age in Nam Phong District of Khon Kaen Province, Thailand. Thiamine deficiency [thiamine pyrophosphate effect (TPPE) > 20%] and parasitic infections (mostly Strongyloides stercoralis) were identified in 16 and 45% of the children, respectively.
